However, whether constraint-induced movement therapy is more effective than conventional rehabilitation in acute or sub-acute stroke remains controversial. The aim of the present study was to identify the optimal time to start constraint-induced movement therapy after ischemic stroke and to explore the mechanisms by which constraint-induced movement therapy leads to post-stroke recovery. Sixty-four adult male Sprague-Dawley rats were randomly divided into four groups: sham-surgery group, cerebral ischemia/reperfusion group, early constraint-induced movement therapy group, and late constraint-induced movement therapy group. Rat models of left middle cerebral artery occlusion were established according to the Zea Longa line embolism method. Constraint-induced movement therapy was conducted starting on day 1 or day 14 in the early constraint-induced movement therapy and late constraint-induced movement therapy groups, respectively. To explore the effect of each intervention time on neuromotor function, behavioral function was assessed using a balance beam walking test before surgery and at 8 and 21 days after surgery. The expression levels of brain-derived neurotrophic factor, nerve growth factor and Nogo receptor were evaluated using real time-polymerase chain reaction and western blot assay to assess the effect of each intervention time. The results showed that the behavioral score was significantly lower in the early constraint-induced movement therapy group than in the cerebral ischemia/reperfusion and late constraint-induced movement therapy groups at 8 days. At 21 days, the scores had significantly decreased in the early constraint-induced movement therapy and late constraint-induced movement therapy groups. At 8 days, only mild pyknosis appeared in neurons of the ischemic penumbra in the early constraint-induced movement therapy group, which was distinctly better than in the cerebral ischemia/reperfusion group. At 21 days, only a few vacuolated cells were observed and no obvious inflammatory cells were visible in late constraint-induced movement therapy group, which was much better than at 8 days. The mRNA and protein expression levels of brain-derived neurotrophic factor and nerve growth factor were significantly higher, but expression levels of Nogo receptor were significantly lower in the early constraint-induced movement therapy group compared with the cerebral ischemia/reperfusion and late constraint-induced movement therapy groups at 8 days. The changes in expression levels at 21 days were larger but similar in both the early constraint-induced movement therapy and late constraint-induced movement therapy groups. Besides, the protein nerve growth factor level was higher in the late constraint-induced movement therapy group than in the early constraint-induced movement therapy group at 21 days. These results suggest that both early(1 day) and late(14 days) constraint-induced movement therapy induces molecular plasticity and facilitates functional recovery after ischemic stroke, as illustrated by the histology. The mechanism may be associated with downregulation of Nogo receptor expression and upregulation of brain-derived neurotrophic factor and nerve growth factor expression.展开更多

DATA SOURCES： The key words were stroke, cerebrovascular accident, constraint-induced therapy, forced use, and randomized controlled trial. The databases, including China National Knowledge Infrastructure, WanFang, Weipu Information Resources System, Chinese Biomedical Literature Database, PubMed, Med- line, Embase, the Cochrane Central Register of Controlled Trials, and the Cochrane Database of Systematic Reviews, were searched for studies on randomized controlled trials for treating acute or sub-acute stroke published before March 2016. DATA SELECTION： We retrieved relevant randomized controlled trials that compared constraint-induced movement therapy in treatment of acute or sub-acute stroke with traditional rehabilitation therapy （tradi- tional occupational therapy）. Patients were older than 18 years, had disease courses less than 6 months, and were evaluated with at least one upper extremity function scale. Study quality was evaluated, and data that met the criteria were extracted. Stata 11.0 software was used for the meta-analysis. OUTCOME MEASURES： Fugl-Meyer motor assessment of the arm, the action research-arm test, a motor activity log for amount of use and quality of movement, the Wolf motor function test, and a modified Bar- thel index. RESULTS： A total of 16 prospective randomized controlled trials （379 patients in the constraint-induced movement-therapy group and 359 in the control group） met inclusion criteria. Analysis showed significant mean differences in favor of constraint-induced movement therapy for the Fugl-Meyer motor assessment of the arm （weighted mean difference （WMD） = 10.822; 95% confidence intervals （95% CI）： 7.419-14.226）, the action research-arm test （WMD = 10.718; 95% CI： 5.704-15.733）, the motor activity log for amount of use and quality of movement （WMD = 0.812; 95% CI： 0.331-1.293） and the modified Barthel index （WMD = 10.706; 95% CI： 4.417-16.966）. CONCLUSION： Constraint-induced movement therapy may be more beneficial than traditional rehabili- tation therapy for improving upper limb function after acute or sub-acute stroke.展开更多

Methods HIV-1 tat genes derived from peripheral spleen and central basal ganglia of an AIDS patient with ADC and an AIDS patient without ADC were cloned for sequence analysis. HIV-1 tat gene sequence alignment was performed by using CLUSTAL W and the phylogentic analysis was conducted by using Neighbor-joining with MEGA4 software. All tat genes were used to construct recombinant retroviral expressing vector MSCV-IRES-GFP/tat. The MSCV-IRES-GFP/tat was cotransfected into 293T cells with pCMV-VSV-G and pUMVC vectors to assemble the recombinant retrovirus. After infection of gliomas U87 cells with equal amount of the recombinant retrovirus, TNF-α, and IL-1β concentrations in the supernatant of U87 cells were determined with ELISA. Results HIV-1 tat genes derived from peripheral spleen and central basal ganglia of the AIDS patient with ADC and the other one without ADC exhibited genetic variations. Tat variations and amino acid mutation sites existed mainly at Tat protein core functional area （38-47aa）. All Tat proteins could induce ug7 cells to produce TNF-α and IL-1β, but the level of IL-1β production was different among Tat proteins derived from the ADC patient＇s spleen, basal ganglia, and the non-ADC patient＇s spleen. The level of Tat proteins derived from the ADC patient＇s spleen, basal ganglia, and the non-ADC patient＇s spleen were obviously higher than that from the non-ADC patient＇s basal ganglia. Conclusion Tat protein core functional area （38-47aa） may serve as the key area of enhancing the secretion of IL-1β. This may be related with the neurotoxicity of HIV-1 Tat.展开更多

The contralateral uninvolved eyes were used as controls. The retinal nerve fiber layer thickness was determined by optical coherence tomography which showed that the mean retinal nerve fiber layer thickness and the retinal nerve fiber layer thickness from temporal, superior, nasal and inferior quadrants were significantly higher for all measurements in the acute stage than the corresponding normal values. In comparison, the retinal nerve fiber layer thickness from each optic disc quadrant was found to be significantly lower when measured at the resolving stages, than in the control group. Statistical analysis on the correlation between optic disc nerve fiber layer thickness and visual defects demonstrated a positive correlation in the acute stage and a negative correlation in the resolving stage. Our experimental findings indicate that optical coherence tomography is a useful diagnostic method for nonarteritic anterior ischemic optic neuropathy and can be used to evaluate the effect of treatment.展开更多

The unification and innovation of cancer pathogenesis is the key to the breakthrough of Chinese medicine. According to the related theory in Neijing, cancer in different parts of the body could be classified based on the five elements. Chinese mainland is divided into five parts： east, south, west, north and central section. Based on the annual data of China Cancer Center, we analyzed the data of 72 cancer registries covering 32 provinces and autonomous regions for consecutive 5 years. The results showed that the total incidence of the five regions in the mainland of China was statistically significant （F = 8.561, P 〈 0.01）; the east was the highest, the west was the lowest, and the south, middle and north were in the middle level. The incidence of tumors in different parts of the human body was statistically significant （F = 523.382, P 〈 0.01）. The incidence rate from high to low was lung, spleen, kidney, liver and heart. The heat is too much in China＇s eastern and the southern, and Qi is not too enough in the northwest. Five-Qi was imbalance. The pathogenesis of cancer is due to the two aspects, deficiency of five Zang-organs and abnormal seasonal climates. The viscera weakness for a long period and abnormal seasonal climates causes the body Yin and Yang disharmony, resulting in five zang organs dysfunction.展开更多

Methods: A randomized, double-blind, double-dummy, and positive paral el control ed clinical trial was conducted from October 2014 to March 2016. Total y 342 patients from 13 clinical centers were enrolled and randomly assigned(at the ratio of 1:1) to a treatment group(171 cases) and a control group(171 cases) by a random coding table. The patients in the treatment group were administered oral y with TXNG(5 g per time) combined with pinaverium bromide Tablet simulator(50 mg per time), 3 times per day. The patients in the control group were given TXNG simulator(5 g per time) combined with pinaverium bromide Tablets(50 mg per time), 3 times per day. The treatment course lasted for 6 weeks. The improvement of Irritable Bowel Syndrome Symptom Severity Score(IBS-SSS) was used to evaluate the primary outcome. Secondary outcomes included adequate relief(AR) rate, Irritable Bowel Syndrome-Quality of Life Questionnaire(IBS-QOL), Hamilton Anxiety Scale(HAMA), Hamilton Depression Scale(HAMD), and the recurrence rate at fol ow-ups. Safety indices including the adverse events(AEs) and related laboratory tests were evaluated. Results: Primary outcome: IBS-SSS at baseline, weeks 2, 4, 6 showed no statistical significance in both full analysis set(FAS) and per protocol set(PPS, P>0.05). After 6 weeks of treatment, the total effective rate of IBS-SSS scores in the treatment group(147/171, 86.0%) was higher than the control group(143/171, 83.6%) by FAS(P>0.05). In regard to secondary outcomes, after 6-week treatment, there was no significant difference in AR rate, total score of IBS-QOL, improvement of HAMD and HAMA total scores between the two groups(P>0.05). The recurrence rate at 8-week fol ow-up was 12.35%(10/18) in treatment group and 15.79%(12/76) in control group, respectivery(P>0.05). A total of 21 AEs occurred in 15 cases, of which 11 occurred in 8 cases in the treatment group and 10 AEs in 7 cases in the control group. The incidence of AEs had no statistical significance between the two goups(P>0.05). Conclusion: Tongxiening Granules could relieve the symptoms of patients with IBS-D and the treatment effect was comparable to pinaverium bromide.(No. ChiCTR-IPR-15006415)展开更多
