Medical treatm...BACKGROUND Hemorrhagic chronic radiation proctitis(CRP) is a common late complication of irradiation of the pelvis and seriously impairs life quality. There is no standard treatment for hemorrhagic CRP. Medical treatment, interventional treatment, and surgery are available, but they are limited in their applications due to nondefinite efficacy or side effects. Chinese herbal medicine(CHM), as a complementary or alternative therapy, may provide another option for hemorrhagic CRP treatment.CASE SUMMARY A 51-year-old woman with cervical cancer received intensity-modulated radiation therapy and brachytherapy with a total dose of 93 Gy fifteen days after hysterectomy and bilateral adnexectomy. She received six additional cycles of chemotherapy with carboplatin and paclitaxel. Nine months after radiotherapy treatment, she mainly complained of 5-6 times diarrhea daily and bloody purulent stools for over 10 d. After colonoscopy examinations, she was diagnosed with hemorrhagic CRP with a giant ulcer. After assessment, she received CHM treatment. The specific regimen was 150 mL of modified Gegen Qinlian decoction(GQD) used as a retention enema for 1 mo, followed by replacement with oral administration of 150 mL of modified GQD three times per day for 5 mo. After the whole treatment, her diarrhea reduced to 1-2 times a day. Her rectal tenesmus and mild pain in lower abdomen disappeared. Both colonoscopy and magnetic resonance imaging confirmed its significant improvement. During treatment,there were no side effects, such as liver and renal function damage.CONCLUSION Modified GQD may be another effective and safe option for hemorrhagic CRP patients with giant ulcers.展开更多

The separation was performed on a Kromasil C18 column （250 mm×4.6 ram, 5.0 μm） by gradient elution with acetonitrile and 0.02 mol/L ammonium acetate （containing 0.3% triethylamine, and adjusted pH to 4.3 using 1% glacial acetic acid） as the mobile phase at a flow rate of 0.7 mL/min. Three different detection wavelengths （250, 280, 346 nm） were set at the maximum UV absorption wavelengths of these components. Twelve components （puerarin, daidzin, baicalin, wogonoside, liquiritin, berberine, palmatine, jatrorrhizine, glycyrrhizin, baicalein, wogonin and daidzein） were identified and determined using the developed method. All calibration curves showed good linear regression （r〉0.9995） within tested ranges. The injection precision, intra-day precisions and analysis repeatability were evaluated with the RSD values, which were no more than 0.97%, 1.69% and 1.71%, respectively. The recoveries were ranged from 97.4% to 100.2% with RSD values less than 1.87%. This readily available, low-cost and reliable HPLC-DAD method would improve the quality control of Gegen Qinlian pill.展开更多

文摘Objective:The study shows that Gegen Qinlian decoction(GGQL)is feasible in the treatment of influenza.It is explained from traditional Chinese medicine theory and modern pharmacology,and the formula is tested in vitro.The results show that Gegen Qinlian decoction has a good inhibitory effect on influenza virus.Methods:Search TCMSP database to get the components and targets of GGQL,and construct the compound target network.Then search OMIM database and Disgenet database to obtain influenza genes,and the common genes were obtained by VennDiagram.STRING database was used to construct gene function association network.Finally,David database was used to analyze GO enrichment and pathway enrichment.Results:146 ingredients and 128 targets were obtained,588 genes were obtained.46 common genes were obtained by VennDiagram,and import the common genes into the STRING database and construct the gene function association network,then the network information data was imported into Cytoscape software for topology analysis.Finally,13 enriched GO clusters and 7 enriched pathway clusters were obtained by David database,and construct the targets-GO-pathway network.Conclusion:Network pharmacology of GGQL reveal that the target and the pathway of the drug was closely related to influenza,and the results of this study have been verified with published experimental studies,which shows that GGQL has not only theoretical basis for the treatment of influenza,but also in vitro experiments support this conclusion.

文摘Gegen Qinlian Decoction is one of the commonly used classical prescriptions,which consists of fourherbs:Gegen(Puerariae Lobatae Radix),Huangqin(Scutellariae Radix),Huanglian(Coptidis Rhizoma),and Zhigancao Glycyrrhizae Radix et Rhizoma Praeparata cum Melle.The clinical application experience of Gegen Qinlian Decoction is as follows:first,according to Zhongjing Zhang's original text,heat distressing the large intestine with unresolved exterior syndrome is theoriginal meaningof Gegen Qinlian Decoction syndrome.In clinical practice,bacillary dysentery,gastrointestinal cold,etc.,belong to simultaneous exterior and interior disease,which are completely consistent with the original meaning of this prescription;second,the clinical digestive system diseases with exuberant heat of the large intestine as the core manifestation cannot be treated merely based on the exterior syndrome;third,due to the interior-exterior relationship between the lung and the large intestine and between the meridians,the use of Gegen(Puerariae Lobatae Radix),Huangqin(Scutellariae Radix),and Huanglian(Coptidis Rhizoma)can make the source of body clear,and the waste qi can be released and thepore can be easily opened,so this prescription can also be used for exogenous fever;fourth,with multidimensional comprehensive understanding of the syndrome,pathogenesis,symptoms and pharmacology,Gegen Qinlian Decoction has also been further applied to the treatment of hypertension,diabetes,etc.

文摘Background:Accumulating evidence suggests that metabolic disorders,including type 2 diabetes mellitus(T2DM),can be treated with traditional Chinese medicine formulas,such as the Gegen Qinlian decoction(GQD).This study elucidates the mechanisms by which gut microbes mediate the anti-diabetic effects of GQD.Methods:We conducted a double-blind randomized clinical trial involving 120 untreated participants with T2DM.During the 12-week intervention,anthropometric measurements and diabetic traits were recorded every 4 weeks.Fecal microbiota and serum metabolites were measured before and after the intervention using 16S rDNA sequencing,liquid chromatography-mass spectrometry,and Bio-Plex panels.Results:Anti-diabetic effects were observed in the GQD group in the human trial.Specifically,glycated hemoglobin,fasting plasma glucose,and two-hour postprandial blood glucose levels were significantly lower in the GQD group than in the placebo group.Additionally,Faecalibacterium was significantly enriched in the GQD group,and the short-chain fatty acid levels were higher and the serum inflammation-associated marker levels were lower in the GQD group compared to the placebo group.Moreover,Faecalibacterium abundance negatively correlated with the levels of serum hemoglobin,fasting plasma glucose,and pro-inflammatory cytokines.Finally,the diabetes-alleviating effect of Faecalibacterium was confirmed by oral administration of Faecalibacterium prausnitzi(DSMZ 17677)in T2DMmousemodel.Conclusions:GQD improved type 2 diabetes primarily by modulating the abundance of Faecalibacterium in the gut microbiota,alleviating metabolic disorders and the inflammatory state.

文摘In this study, a novel and simple high performance liquid chromatography with diode array detection （HPLC-DAD） method for the simultaneous qualitative and quantitative determination of 12 bioactive components in Gegen Qinlian pill was developed. The separation was performed on a Kromasil C18 column （250 mm×4.6 ram, 5.0 μm） by gradient elution with acetonitrile and 0.02 mol/L ammonium acetate （containing 0.3% triethylamine, and adjusted pH to 4.3 using 1% glacial acetic acid） as the mobile phase at a flow rate of 0.7 mL/min. Three different detection wavelengths （250, 280, 346 nm） were set at the maximum UV absorption wavelengths of these components. Twelve components （puerarin, daidzin, baicalin, wogonoside, liquiritin, berberine, palmatine, jatrorrhizine, glycyrrhizin, baicalein, wogonin and daidzein） were identified and determined using the developed method. All calibration curves showed good linear regression （r〉0.9995） within tested ranges. The injection precision, intra-day precisions and analysis repeatability were evaluated with the RSD values, which were no more than 0.97%, 1.69% and 1.71%, respectively. The recoveries were ranged from 97.4% to 100.2% with RSD values less than 1.87%. This readily available, low-cost and reliable HPLC-DAD method would improve the quality control of Gegen Qinlian pill.
