RESULTS: Endothelial cell density, mean cell area,coefficient of variation in cell size, percentage hexagonality and central corneal thickness in the study population were(2969.50 ±253.93) cells/mm2,(339.23 ±29.44) μm2,(29.96 ±4.07) %,(64.58 ±9.41) % and(523.71 ±32.82) μm in Maonan and(2998.26 ±262.65) cells/mm2,(336.11±30.07) μm2,(29.89±5.03) %,(64.91±11.64) % and(524.39 ±33.15) μm in Han, respectively. No significant differences were observed in endothelial cell density,mean cell area, coefficient of variation in cell size,percentage hexagonality and central corneal thickness between Maonan and Han(P =0.615, 0.659, 0.528, 0.551,0.999). In Maonan and Han, we found age was negatively correlated with endothelial cell density and percentagehexagonality and positively correlated with mean cell area and coefficient of variation in cell size. Negative correlation was also found between central corneal thickness and age in Han, whereas no correlation was found in Maonan. CONCLUSION: There were no differences between Maonan and Han in corneal endothelial cell density and morphology and central corneal thickness.

Methods： A multi-center cohort retrospective comparative study of population among 4,895 hysterectomies （3,539 LH vs.1,356 AH） between 2007 and 2013 was involved. Operative time （OT）, estimated blood loss （EBL）, intra-operative and post-operative complications, passing flatus; days with indwelling catheter, questionnaires covering pelvic floor functions and sexual functions were assessed. Results： The EBL （174.1±157.4 vs. 263.1±183.2 cc, LH and AH groups, respectively）, passing flatus （38.7±14.1 vs. 48.1±13.2 hours）, days with indwelling catheter （1.5±0.6 vs. 2.2±0.8 days）, use of analgesics （6.5% vs. 73.1%）, intra-operative complication rate （2.4% vs. 4.1%）, post-operative complication rate （2.3 % vs. 5.7%）, post-operative constipation （12.1% vs. 24.6%）, mild and serious stress urinary incontinence （SUI） post-operative （P〈0.001; P=0.014）, and proportion of Female Sexual Functioning Index （FSFI） total score 〈26.55 post-operative （P〈0.001） of the LH group were significantly less than those of AH group. There were no significant differences in OT （106.5±34.5 vs. 106.2±40.3 min） between the two groups. Conclusions： LH is a safe and efficient operation for improving patients＇ long-term quality of life （QoL）, and LH is a cost-effectiveness procedure for treating benign gynecological disease. LH is superior to AH due to reduced EBL, reduced post-operative pain and earlier passing flatus.展开更多

文摘BACKGROUND Radiotherapy stands as a promising therapeutic modality for colorectal cancer(CRC);yet,the formidable challenge posed by radio-resistance significantly undermines its efficacy in achieving CRC remission.AIM To elucidate the role played by microRNA-298(miR-298)in CRC radio-resistance.METHODS To establish a radio-resistant CRC cell line,HT-29 cells underwent exposure to 5 gray ionizing radiation that was followed by a 7-d recovery period.The quantification of miR-298 levels within CRC cells was conducted through quantitative RT-PCR,and protein expression determination was realized through Western blotting.Cell viability was assessed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay and proliferation by clonogenic assay.Radio-induced apoptosis was discerned through flow cytometry analysis.RESULTS We observed a marked upregulation of miR-298 in radio-resistant CRC cells.MiR-298 emerged as a key determinant of cell survival following radiation exposure,as its overexpression led to a notable reduction in radiation-induced apoptosis.Intriguingly,miR-298 expression exhibited a strong correlation with CRC cell viability.Further investigation unveiled human dual-specificity tyrosine(Y)-regulated kinase 1A(DYRK1A)as miR-298’s direct target.CONCLUSION Taken together,our findings underline the role played by miR-298 in bolstering radio-resistance in CRC cells by means of DYRK1A downregulation,thereby positioning miR-298 as a promising candidate for mitigating radioresistance in CRC.
文摘BACKGROUND Avulsion fracture of the ischial tuberosity is a relatively clinically rare type of trauma that is mainly incurred by adolescents during competitive sports activities.According to previous literature,the most commonly involved sports are soccer,sprinting,and gymnastics,in descending order.Dance-induced avulsion fracture of the ischial tuberosity and ischial ramus is extremely clinically rare.CASE SUMMARY A case of a neglected avulsion fracture of the ischial tuberosity and ischial ramus was diagnosed in a young female dancer who complained of pain and restricted movement of her right hip.She stated that she had suffered the injury while performing a split leap during a dance performance 9 mo prior.Eventually,she underwent surgery and obtained satisfactory treatment results.CONCLUSION Early diagnosis of these fractures is important to ensuring early proper treatment towards a quicker recovery.For old fractures with nonunion and chronic buttock pain,surgery is a preferred therapeutic choice with good treatment outcomes.

文摘BACKGROUND Transcatheter arterial embolisation(TACE)is the primary treatment for intermediate-stage hepatocellular carcinoma(HCC)patients while some HCC cases have shown resistance to TACE.AIM To investigate the key genes and potential mechanisms correlated with TACE refractoriness in HCC.METHODS The microarray datasets of TACE-treated HCC tissues,HCC and non-HCC tissues were collected by searching multiple public databases.The respective differentially expressed genes(DEGs)were attained via limma R package.Weighted gene co-expression network analysis was employed for identifying the significant modules related to TACE non-response.TACE refractoriness-related genes were obtained by intersecting up-regulated TACE-associated and HCC-associated DEGs together with the genes in significant modules related to TACE nonresponse.The key genes expression in the above two pairs of samples was compared respectively via Wilcoxon tests and standard mean differences model.The prognostic value of the key genes was evaluated by Kaplan-Meier curve.Multivariate analysis was utilised to investigate the independent prognostic factor in key genes.Single-cell RNA(scRNA)sequencing analysis was conducted to explore the cell types in HCC.TACE refractoriness-related genes activity was calculated via AUCell packages.The CellChat R package was used for the investigation of the cell–cell communication between the identified cell types.RESULTS HCC tissues of TACE non-responders(n=66)and TACE responders(n=81),HCC(n=3941)and non-HCC(n=3443)tissues were obtained.The five key genes,DLG associated protein 5(DLGAP5),Kinesin family member 20A(KIF20A),Assembly factor for spindle microtubules(ASPM),Kinesin family member 11(KIF11)and TPX2 microtubule nucleation factor(TPX2)in TACE refractoriness-related genes,were identified.The five key genes were all up-regulated in the TACE non-responders group and the HCC group.High expression of the five key genes predicted poor prognosis in HCC.Among the key genes,TPX2 was an independent prognostic factor.Four cell types,hepatocytes,embryonic stem cells,T cells and B cells,were identified in the HCC tissues.The TACE refractoriness-related genes expressed primarily in hepatocytes and embryonic stem cells.Hepatocytes,as the providers of ligands,had the strongest interaction with embryonic stem cells that provided receptors.CONCLUSION Five key genes(DLGAP5,KIF20A,ASPM,KIF11 and TPX2)were identified as promoting refractory TACE.Hepatocytes and embryonic stem cells were likely to boost TACE refractoriness.
文摘BACKGROUND Lung cancer bone metastasis(LCBM)is a disease with a poor prognosis,high risk and large patient population.Although considerable scientific output has accumulated on LCBM,problems have emerged,such as confusing research structures.AIM To organize the research frontiers and body of knowledge of the studies on LCBM from the last 22 years according to their basic research and translation,clinical treatment,and clinical diagnosis to provide a reference for the development of new LCBM clinical and basic research.METHODS We used tools,including R,VOSviewer and CiteSpace software,to measure and visualize the keywords and other metrics of 1903 articles from the Web of Science Core Collection.We also performed enrichment and proteinprotein interaction analyses of gene expression datasets from LCBM cases worldwide.RESULTS Research on LCBM has received extensive attention from scholars worldwide over the last 20 years.Targeted therapies and immunotherapies have evolved into the mainstream basic and clinical research directions.The basic aspects of drug resistance mechanisms and parathyroid hormone-related protein may provide new ideas for mechanistic study and improvements in LCBM prognosis.The produced molecular map showed that ribosomes and focal adhesion are possible pathways that promote LCBM occurrence.CONCLUSION Novel therapies for LCBM face animal testing and drug resistance issues.Future focus should centre on advancing clinical therapies and researching drug resistance mechanisms and ribosome-related pathways.

文摘Background:This study compared the validity of the creatinine-to-cystatin C ratio(CCR),sarcopenia index(SI),and relative skeletalmuscle index(RSMI)as predictors of sarcopenia in patients with colorectal cancer(CRC)and explored their impact on the patient prognosis.Methods:We retrospectively studied patients with CRC who underwent surgical intervention at the Department of Colorectal and Anal Surgery,situatedwithin the First Affiliated Hospital of GuangxiMedical University.The investigation spanned from January 2015 to December 2017,encompassing a cohort of patients subject to surgical management forCRC during this period.Pearson’s correlation analysis was employed to evaluate the relationships between the CCR,SI,RSMI,and skeletal muscle index(SMI)and the patient prognosis.Receiver operating characteristic(ROC)curves were generated to evaluate the predictive precision of these biomarkers and ascertain the optimal cutoff values.Multivariate logistic regression analysis was conducted to pinpoint the independent factors linked with sarcopenia.Survival analyses,contingent on different surrogate markers of muscle mass and sarcopenia,were performed utilizing the Kaplan-Meier method alongside the log-rank test.Results:Weenrolled 815 patientswithCRC(522 male and 293 female patients)whowere eligible for the analysis.In accordancewith the guidelines set forth by the International Consensus on Sarcopenia,sarcopenia was diagnosed in a collective total of 503 patients.A Pearson’s correlation coefficient(r)analysis demonstrated that the CCR,SI,and RSMI were positively correlated with the SMI.In both male and female patients,the RSMI(male:r=0.400,P<0.001;female:r=0.640,P<0.001)was more strongly correlated with the SMI than with the CCR(male:r=0.203,P<0.001;female:r=0.192,P<0.001)or SI(male:r=0.335,P<0.001;female:r=0.285,P<0.001).In male patients,the areas under the ROC curves(AUC)for the CCR,SI,and RSMI were 0.596[(95%confidence interval(CI)=0.545-0.647)],0.648(95%CI=0.599-0.698),and 0.681(95%CI=0.629-0.733),respectively.In female patients,the AUC for the CCR,SI,and RSMI were 0.615(95%CI=0.551-0.680),0.660(95%CI=0.598-0.722),and 0.772(95%CI=0.719-0.825),respectively.A multivariable logistic regression analysis demonstrated that the CCR remained an influential factor for sarcopenia after correcting for confounding[odds ratio(OR)=0.993,95%CI=0.986-1.000,P=0.038].The SI and RSMI also remained influential factors for sarcopenia after correcting for confounding factors(OR=0.983,95%CI=0.972-0.994,P=0.002;and OR=0.401,95%CI=0.320-0.502,P<0.001,respectively).The groups characterized by low CCR and SI demonstrated notably reduced overall survival compared with their counterparts with high CCR and SI(P=0.007 and P=0.001,respectively),whereas the RSMI and sarcopenia did not exhibit a significant correlation with survival(P=0.608 and P=0.062,respectively).Conclusions:The CCR,SI,and RSMI all have predictive value for sarcopenia in patients with CRC.TheRSMI was a better predictor of sarcopenia than either the CCR or SI in both male and female patientswith CRC.However,the RSMI did not have any significant value for predicting the prognosis of patients with CRC.Subsequent prospective investigations are warranted to elucidate a superiormarker or amalgamation thereof,capable of accurately prognosticating sarcopenia and the overall prognosis in individuals diagnosed with CRC.Such studies should aim to meticulously evaluate a comprehensive array of potential markers,considering their individual and collective predictive value in delineating the clinical trajectory of CRC patients.By conducting rigorous prospective analyses,researchers can strive to uncover novel insights into the complex interplay between sarcopenia and CRC outcomes,thereby facilitating the development of more precise prognostic models and tailored therapeutic approaches.

文摘Background:The Asian Working Group for Cachexia(AWGC)criteria are newly proposed diagnostic standards specifically designed for Asian populations.This research focused on validating the predictive value of the AWGC criteria for assessing the prognosis and medical burden of patients with gastric cancer.Methods:Cox proportional hazards analysis was conducted to evaluate the association between cachexia and overall survival.Logistic regression analysis was used to assess whether there was an independent association between cachexia and the 90-day mortality,the length of stay and the quality of life.Harrell’s concordance index was utilized to demonstrate the discriminative ability of different diagnostic criteria for cachexia.Results:AWGC-defined cachexia was an independent risk factor for a reduced overall survival in patients(HR=1.397,95%CI=1.209–1.615,P<0.001).The predictive accuracy of the AWGC criteria was markedly superior to that of the Fearon criteria(χ2=39.025 vs 13.877).Compared with Fearon standards,the AWGC criteria offered a 2.9%enhancement in clinical benefit(0.029,95%CI=0.048–0.008,P=0.005).Logistic regression analysis showed that only AWGC-defined cachexia was an independent risk factor for 90-day mortality(OR=2.142,95%CI=1.397–3.282,P<0.001)and prolonged hospitalization(OR=1.958,95%CI=1.587–2.416,P<0.001)in patients with gastric cancer,whereas cachexia defined by the Fearon criteria was not.Patients with AWGC-defined cachexia exhibited significant reductions in physical function,role function,emotional function,cognitive function,social functioning,and overall quality-of-life scores.Conversely,cachectic patients showed higher levels of fatigue,nausea and vomiting,pain,dyspnea,sleep disturbance,appetite loss,constipation,and financial difficulties.A multivariate logistic regression showed that patients with AWGC-defined cachexia had a 126.1%increased risk of impaired quality of life(OR=2.261,95%CI=1.859–2.749,P<0.001).Conclusions:The AWGC criteria are an effective tool for predicting adverse survival outcomes,90-day mortality,a prolonged hospital stay,and poorer quality of life in patients with gastric cancer.

文摘Methylprednisolone pulse treatment is currently used fo r optic neuritis.It can speed visual recovery,but does not improve the ultimate visual outcomes.Recent studies have repo rted that miR-125 a-5 p has immunomodulatory effects on autoimmune diseases.However,it remains unclear whether miR-125 a-5 p has effects on optic neuritis.In this study,we used adeno-associated virus to overexpress or silence miR-125 a-5 p in mice.We found that silencing miR-125 a-5 p increased the latency of visual evoked potential and aggravated inflammation of the optic nerve.Ove rexpression of miR-125 a-5 p suppressed inflammation of the optic nerve,protected retinal ganglion cells,and increased the percentage of Treg cells.Our findings show that miR-125 a-5 p exhibits anti-inflammatory effects through promoting the diffe rentiation of Treg cells.

文摘Drug delivery via intra-articular(IA)injection has proved to be effective in osteoarthritis(OA)therapy,limited by the drug efficiency and short retention time of the drug delivery systems(DDSs).Herein,a series of modified cross-linked dextran(Sephadex,S0)was fabricated by respectively grafting with linear alkyl chains,branched alkyl chains or aromatic chain,and acted as DDSs after ibuprofen(Ibu)loading for OA therapy.This DDSs expressed sustained drug release,excellent anti-inflammatory and chondroprotective effects both in IL-1βinduced chondrocytes and OA joints.Specifically,the introduction of a longer hydrophobic chain,particularly an aromatic chain,distinctly improved the hydrophobicity of S0,increased Ibu loading efficiency,and further led to significantly improving OA therapeutic effects.Therefore,hydrophobic microspheres with greatly improved drug loading ratio and prolonged degradation rates show great potential to act as DDSs for OA therapy.

文摘Spine degeneration is an aging-related disease,but its molecular mechanisms remain unknown,although elevatedβ-catenin signaling has been reported to be involved in intervertebral disc degeneration.Here,we determined the role ofβ-catenin signaling in spinal degeneration and in the homeostasis of the functional spinal unit(FSU),which includes the intervertebral disc,vertebra and facet joint and is the smallest physiological motion unit of the spine.We showed that pain sensitivity in patients with spinal degeneration is highly correlated withβ-catenin protein levels.We then generated a mouse model of spinal degeneration by transgenic expression of constitutively activeβ-catenin in Col2^(+) cells.We found thatβ-catenin-TCF7 activated the transcription of CCL2,a known critical factor in osteoarthritic pain.Using a lumbar spine instability model,we showed that aβ-catenin inhibitor relieved low back pain.Our study indicates thatβ-catenin plays a critical role in maintaining spine tissue homeostasis,its abnormal upregulation leads to severe spinal degeneration,and its targeting could be an avenue to treat this condition.

文摘Background:Kinesin family member 15(KIF15)is a protein that regulates cell mitosis and plays an important role in the development and progression of several types of human cancers.However,the role of KIF15 in the development of nasopharyngeal cancer(NPC)is still unclear.Methods:The differential expression of KIF15 in NPC and para-carcinoma tissues was evaluated based on data collected from Gene Expression Omnibus(GEO)database and immunohistochemical analysis of clinical specimens collected from a patient cohort.Cell lines 5-8F and CNE-2Z were selected for the construction of KIF15‑knockdown cell models.CCK8 assay,flow cytometry,wound healing,Transwell and clone formation assays were used to detect the proliferation,apoptosis,migration,invasion and colony formation of NPC cells in vitro.A mouse xenograft model and the tail intravenous mouse distant transfer model were constructed for in vivo study.Furthermore,the potential molecular mechanisms underlying the effects of KIF15 were explored through western blot analysis,and several in vitro and in vivo functional assays were performed to explore its role in NPC.Results:The results revealed significantly higher expression of KIF15 in NPC tissues compared to para-carcinoma tissues.High levels of KIF15 expression were also associated with short overall survival(OS)and progression-free survival(PFS).Knockdown of the KIF15 gene led to a cell cycle arrest in the growth 2(G2)phase,inhibition of cell proliferation,migration,invasion,colony formation,and enhanced cell apoptosis.The in vivo murine xenograft experiments showed that down-regulation of the KIF15 gene could inhibit tumor growth and reduce the risk of liver and lung metastasis in NPC.Moreover,the evaluation of the molecular pathway showed that the mitogen-activated protein kinase/P53 pathways might be involved in the KIF15-induced regulation of NPC.Rescue assays indicated that Pifithrin-αcould counteract the pro-proliferative and pro-apoptotic effects mediated by KIF15.Conclusion:This work indicated that KIF15 overexpression accelerated the progression of NPC and promoted the development of distant metastases.Therefore,KIF15 may have an important role as a prognostic indicator and a potential drug target for the treatment of NPC.

文摘BACKGROUND Nonalcoholic fatty liver disease(NAFLD)has become the leading cause of cirrhosis and other chronic liver diseases(COCLDs).AIM To conduct a comprehensive and comparable updated analysis of the global,regional,and national burden of COCLDs due to NAFLD in 204 countries and territories from 1990 and 2019 by age,sex,and sociodemographic index.METHODS Data on COCLDs due to NAFLD were collected from the Global Burden of Diseases,Injuries,and Risk Factors Study 2019.Numbers and age-standardized prevalence,death,and disability-adjusted life years(DALYs)were estimated through a systematic analysis of modelled data from the Global Burden of Diseases,Injuries,and Risk Factors Study 2019.The estimated annual percentage change was used to determine the burden trend.RESULTS In 2019,the global age-standardized prevalence rate of COCLDs due to NAFLD was 15022.90 per 100000 population[95%uncertainty interval(UI):13493.19-16764.24],which increased by 24.51%(22.63%to 26.08%)from 1990,with an estimated annual percentage change of 0.78(95%confidence interval:0.74-0.82).In the same year,however,the age-standardized death rate and age-standardized DALYs per 100000 population were 1.66(95%UI:1.20-2.17)and 43.69(95%UI:31.28-58.38),respectively.North Africa and the Middle East had the highest prevalence rates of COCLDs due to NAFLD.The death rate increased with age up to the 95+age group for both sexes.Males had higher numbers of prevalence,death rate,and DALYs than females across all age groups before the 65-69 age group.The sociodemographic index was negatively correlated with the age-standardized DALYs.CONCLUSION Globally,the age-standardized prevalence rate has increased during the past three decades.However,the agestandardized death rate and age-standardized DALYs decreased.There is geographical variation in the burden of COCLDs due to NAFLD.It is strongly recommended to improve the data quality of COCLDs due to NAFLD across all countries and regions to facilitate better monitoring of the burden of COCLDs due to NAFLD.

文摘Background:Cardiac surgery-associated acute kidney injury(CSA-AKI)is a major complication that increases morbidity and mortality after cardiac surgery.Most established predictive models are limited to the analysis of nonlinear relationships and do not adequately consider intraoperative variables and early postoperative variables.Nonextracorporeal circulation coronary artery bypass grafting(off-pump CABG)remains the procedure of choice for most coronary surgeries,and refined CSA-AKI predictive models for off-pump CABG are notably lacking.Therefore,this study used an artificial intelligence-based machine learning approach to predict CSA-AKI from comprehensive perioperative data.Methods:In total,293 variables were analysed in the clinical data of patients undergoing off-pump CABG in the Department of Cardiac Surgery at the First Affiliated Hospital of Guangxi Medical University between 2012 and 2021.According to the KDIGO criteria,postoperative AKI was defined by an elevation of at least 50%within 7 days,or 0.3 mg/dL within 48 hours,with respect to the reference serum creatinine level.Five machine learning algorithms—a simple decision tree,random forest,support vector machine,extreme gradient boosting and gradient boosting decision tree(GBDT)—were used to construct the CSA-AKI predictive model.The performance of these models was evaluated with the area under the receiver operating characteristic curve(AUC).Shapley additive explanation(SHAP)values were used to explain the predictive model.Results:The three most influential features in the importance matrix plot were 1-day postoperative serum potassium concentration,1-day postoperative serum magnesium ion concentration,and 1-day postoperative serum creatine phos-phokinase concentration.Conclusion:GBDT exhibited the largest AUC(0.87)and can be used to predict the risk of AKI development after surgery,thus enabling clinicians to optimise treatment strategies and minimise postoperative complications.
文摘BACKGROUND In the translational therapy of giant hepatocellular carcinoma(HCC),hepatic arterial infusion chemotherapy(HAIC)combined with anti-PD-1 immunotherapy and tyrosine kinase inhibitors(TKI)after laparoscopic portal vein ligation(PVL)is extremely rare.This is a dual conversion therapy that combines surgery and oncology.Here,we report two cases of successful surgical completion after dual conversion therapy.CASE SUMMARY We report that a 54-year-old man and a 69-year-old woman were diagnosed with primary HCC combined with hepatitis B cirrhosis(case 2 also combined with fatty liver)on physical examination.Due to the insufficient residual liver volume assessed before surgery,laparoscopic right PVL was performed,followed by HAIC combined with anti-PD-1 immunotherapy and TKI.Finally,surgical resection was successfully completed,and pathology confirmed that the tumor was mostly necrotic(90%)in one case,and no live tumor tissue was found in the other case.CONCLUSION In the process of surgical transformation,our treatment plan takes into account the control and transformation of oncology at the same time,which is expected to provide more opportunities for radical hepatectomy and improve the prognosis of patients with large liver cancer.

文摘AIM: To investigate the corneal endothelial cell density and morphology and central corneal thickness in the Guangxi Maonan and Han adolescent students of China.METHODS: Noncontact specular microscope(Topcon SP3000 P, Tokyo, Japan) was performed in 133 adolescent students of Maonan nationality(M:F 54:79)and 105 adolescent students of Han nationality(M:F 50:55),5 to 20 y of age, who were randomly selected from 3schools in Huanjiang Maonan Autonomous County of Guangxi Zhuang Autonomous Region of China.Parameters studied included endothelial cell density,mean cell area, coefficient of variation in cell size,percentage hexagonality and central corneal thickness. RESULTS: Endothelial cell density, mean cell area,coefficient of variation in cell size, percentage hexagonality and central corneal thickness in the study population were(2969.50 ±253.93) cells/mm2,(339.23 ±29.44) μm2,(29.96 ±4.07) %,(64.58 ±9.41) % and(523.71 ±32.82) μm in Maonan and(2998.26 ±262.65) cells/mm2,(336.11±30.07) μm2,(29.89±5.03) %,(64.91±11.64) % and(524.39 ±33.15) μm in Han, respectively. No significant differences were observed in endothelial cell density,mean cell area, coefficient of variation in cell size,percentage hexagonality and central corneal thickness between Maonan and Han(P =0.615, 0.659, 0.528, 0.551,0.999). In Maonan and Han, we found age was negatively correlated with endothelial cell density and percentagehexagonality and positively correlated with mean cell area and coefficient of variation in cell size. Negative correlation was also found between central corneal thickness and age in Han, whereas no correlation was found in Maonan. CONCLUSION: There were no differences between Maonan and Han in corneal endothelial cell density and morphology and central corneal thickness. In these two nationalities, there were statistically significant decrease in endothelial cell density and percentage hexagonality with increasing age and statistically significant increase in cell area and coefficient of variation in cell size with increasing age. Central corneal thinned with increasing age in Han, whereas difference did not attain statistical significance in Maonan.

文摘Background： To evaluate the short-term and long-term outcomes after laparoscopic hysterectomy （LH） compared with abdominal hysterectomy （AH） in case of benign gynecological disease. Methods： A multi-center cohort retrospective comparative study of population among 4,895 hysterectomies （3,539 LH vs.1,356 AH） between 2007 and 2013 was involved. Operative time （OT）, estimated blood loss （EBL）, intra-operative and post-operative complications, passing flatus; days with indwelling catheter, questionnaires covering pelvic floor functions and sexual functions were assessed. Results： The EBL （174.1±157.4 vs. 263.1±183.2 cc, LH and AH groups, respectively）, passing flatus （38.7±14.1 vs. 48.1±13.2 hours）, days with indwelling catheter （1.5±0.6 vs. 2.2±0.8 days）, use of analgesics （6.5% vs. 73.1%）, intra-operative complication rate （2.4% vs. 4.1%）, post-operative complication rate （2.3 % vs. 5.7%）, post-operative constipation （12.1% vs. 24.6%）, mild and serious stress urinary incontinence （SUI） post-operative （P〈0.001; P=0.014）, and proportion of Female Sexual Functioning Index （FSFI） total score 〈26.55 post-operative （P〈0.001） of the LH group were significantly less than those of AH group. There were no significant differences in OT （106.5±34.5 vs. 106.2±40.3 min） between the two groups. Conclusions： LH is a safe and efficient operation for improving patients＇ long-term quality of life （QoL）, and LH is a cost-effectiveness procedure for treating benign gynecological disease. LH is superior to AH due to reduced EBL, reduced post-operative pain and earlier passing flatus.
