Research methods and applications progress on spectrum-effect relationships in study of traditional Chinese medicine / 中国中药杂志

The application of chemical fingerprint to evaluate the quality of traditional Chinese medicine has been widely accepted and used in many countries. However,only by analyzing the type and content of its chemical components to evaluate the quality of traditional Chinese medicines,the gold standard of quality evaluation by evaluating pharmacodynamic effects is ignored. The study of Chinese medicinal spectrum-effect relationships combining the chemical composition with the pharmacodynamic activity of traditional Chinese medicine,which can evaluate the quality of traditional Chinese medicine from more comprehensive and different angles,has been applied in many fields of traditional Chinese medicine research. This paper mainly summarizes the research methods of the Chinese medicinal spectrum-effect relationships and its application in the field of traditional Chinese medicine study,and provides reference for the research,development and application of the Chinese medicinal spectrum-effect relationships.

Factors influencing the postoperative resolution of varicocele-associated scrotal pain / 中华男科学杂志

Objective@#To investigate the factors influencing the postoperative resolution of varicocele-associated scrotal pain.@*METHODS@#Using the keywords "varicocele", "testicular pain", "scrotal pain", "painful varicocele", "ligation", and "varicocelectomy", we searched the PubMed, Embase, Cochrane Collaboration's Database, CNKI, Wanfang, and VIP Database up to October 2016 for the studies relating to surgical treatment of varicocele-associated scrotal pain. We assessed the quality of the cohort studies included using the Newcastle-Ottawa Scale and that of the randomized controlled trials included with the Cochrane Collaboration's tool. We conducted a meta-analysis using the RevMan software.@*RESULTS@#Finally 14 studies were included in this meta-analysis, of which, 2 involved the history of disease, 8 involved the nature of pain, 2 involved the intensity of pain, 9 involved the grade of varicocele, 3 involved the side of varicocele, 9 involved surgical approaches, 3 involved surgical techniques, and 4 involved postoperative recurrence. The pain resolution rate was significantly higher after subinguinal ligation than after high or inguinal ligation (RR = 0.82, 95% CI: 0.76－0.89, P <0.01; RR = 0.92, 95% CI: 0.86－0.99, P = 0.02), and so was it after microsurgery than after laparoscopic varicocelectomy (RR = 0.77, 95% CI: 0.60－0.99, P = 0.04).@*CONCLUSIONS@#Subinguinal varicocelectomy and microsurgery are more effective options than laparoscopic and high or trans-inguinal ligation of the spermatic vein for resolution of varicocele-associated scrotal pain, while the history of disease, the nature and intensity of pain, the grade and side of varicocele, or postoperative recurrence cannot be regarded as the influencing factors.

Yijingfang for the treatment of asthenospermia: A randomized controlled clinical trial / 中华男科学杂志

Objective@#To investigate the clinical therapeutic effects of Yijingfang, a Chinese medicinal liquid, on asthenospermia.@*METHODS@#We randomly divided 450 asthenospermia patients into a treatment group (n = 300) and a control group (n = 150), the former treated with Yijingfang once half a dose, bid, and the latter with Wuziyanzong Pills (9 g, bid) + L-carnitine oral liquid (10 ml, bid), both for 3 months. Before and at 1, 2, and 3 months after medication, we compared the semen volume, sperm concentration, percentages of progressively motile sperm (PMS) and total motile sperm (TMS), and semen liquefaction time between the two groups of patients.@*RESULTS@#No statistically significant difference was observed in the semen parameters between the treatment and control groups before medication (P >0.05). In comparison with the baseline, the treatment group showed significant differences at 1, 2, and 3 months after medication in sperm concentration (［35.96 ± 8.50］ vs ［49.66 ± 10.91］, ［55.21 ± 11.46］, ［74.90 ± 13.07］ ×10⁶/ml, P 0.05) or semen liquefaction time (［32.31 ± 8.15］ vs ［31.68 ± 3.14］, ［30.38 ± 3.44］, and ［30.86 ± 2.42］ min, P >0.05); the control group exhibited similar results at the three time points in sperm concentration (［36.85 ± 6.88］ vs ［40.53 ± 8.32］, ［47.51 ± 12.73］, and ［56.14 ± 11.98］ ×10⁶/ml, P 0.05) or semen liquefaction time (［30.25 ± 5.20］ vs ［29.36±4.25］, ［28.21±3.26］, and ［28.33±3.59］ min, P >0.05). There were statistically significant differences between the treatment and control groups in the increase rates of sperm concentration and TMS after medication (P 0.05).@*CONCLUSIONS@#Yijingfang is an effective drug for the treatment of asthenospermia, which can regulate the spermatogenesis, increase the percentage of PMS, and improve the total sperm motility of the patients.

Objective] To evaluate the influence of metabolic syndrome ( MS) on carotid intima-media thickness ( IMT) in essential hypertension ( EH) . [ Methods] A total of 168 young and middle-aged EH patients were divided into MS group (88 cases) and non-MS group (80 cases).Between the two groups were measured and compared IMT , body mass index ( BMI ) , waist circumference ( WC ) , systolic blood pressure ( SBP ) , diastolic blood pressure ( DBP ) , fasting plasma glucose ( FPG ) , total cholesterol (TC),triglyceride (TG),high-density lipoprotein (HDL-C),low-density lipoprotein (LDL-C) and others. [ Results] Comparison between MS group and non-MS group showed that the level of BMI , FPG, WC, TC, TG, LDL-C and IMT were higher in MS group,P all <0.05.Multiple Logistic regression analysis showed that age,SBP,FPG and LDL-C were the related factors for carotid IMT. [Conclusion] MS is associated with carotid IMT in young and middle-aged patients with EH .MS and EH may jointly participate in the process of atherosclerosis .Apart from control of blood pressure , correction of metabolic disorders is also necessary in order to prevent complication of atherosclerosis .

Effect of endothelial PAS domain protein 1 and hypoxia inducible factor 1alpha on vascular endothelial growth factor expression in human pancreatic carcinoma / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Transcription factors hypoxia inducible factor 1alpha (HIF 1alpha) and endothelial PAS domain protein 1 (EPAS1) promote the transcription of vascular endothelial growth factor (VEGF). VEGF enhances angiogenesis and vascular permeability of tumours, which promotes tumour growth and facilitates entry of cancer cells into blood circulation and metastasizing. This study examined whether HIF 1alpha and EPAS1 stimulated angiogenesis through activation of VEGF in human pancreatic carcinoma.</p><p><b>METHODS</b>Specimens from pancreatic carcinoma and healthy parts of same pancreas were taken from 60 patients. Real time quantitative reverse transcription polymerase chain reaction estimated expression of HIF 1alpha, EPAS1, and VEGF mRNAs. Western blotting and immunohistochemical, streptavidin peroxidase method assessed expression of HIF 1alpha, EPAS1, and VEGF proteins. Microvessel density (MVD) was assessed.</p><p><b>RESULTS</b>Highly significant increases in expression of EPAS1, VEGF, and MVD were found in pancreatic carcinoma tissue but not in normal pancreatic tissue: VEGF at mRNA and protein levels (t = 17.32, P = 0.0001; t = 98.41, P = 0.0001); EPAS1 protein level (t = 22.51, P = 0.0001). Expression of HIF 1alpha was similar in pancreatic carcinoma and normal pancreatic tissues at both mRNA and protein levels. Significant correlations were observed between EPAS1 and VEGF (r = 0.736, P = 0.0041), between VEGF and MVD (r = 0.858, P = 0.0001), and between EPAS1 and MVD (r = 0.641, P = 0.0003). No significant correlations were observed between HIF 1alpha and VEGF, or between HIF 1alpha and MVD. MVD and expression of EPAS1 and VEGF were significantly related with TNM staging, so was EPASI and VEGF with size of tumour.</p><p><b>CONCLUSIONS</b>EPAS1 and VEGF, but not HIF1alpha, are overexpressed in pancreatic carcinoma. The expression of EPAS1 is correlated with that of VEGF and MVD. EPAS1 may be involved in the angiogenesis of pancreatic carcinoma by upregulating the expression of VEGF. Targeting EPAS1 may be a new method of antiangiogenic tumour therapy for pancreatic carcinoma.</p>
