Studies of biological feedback (BF) for the treatment of chronic prostatitis (CP) are occasionally reported have exhibited some related problems. This article presents an evaluation of the published literature on the BF treatment of CP at home and abroad in the aspects of instrument, method, application, effect, function, and mechanism. UROSTYMTM and MyoTrac are often employed and their operating paths are basically the same. NIH prostate symptom scores, urinary function, pain, sexual function, immune function, prostate fluid, and other indicators are generally used for the analysis of the effects of BF alone or in combination with other therapies on CP and its related symptoms. Either BF alone or BF combined with other therapies can promote urination, reduce pain, improve the quality of life, attenuate inflammation, improve sexual function, adjust immunity, and lessen physical and chemical stimulation. However, the relevant literature is of low quantity and quality, the reported studies are not standardized, and exploration of the action mechanisms is neglected.

OBJECTIVETo observe the effects of different therapeutic methods and the recipes of Chinese medicine (CM) on the activation of c-Jun N-terminal kinase (JNK) in Kupffer cells of rats with fatty liver disease and to explore the mechanisms of these therapeutic methods.

METHODSBy using a random number table, 98 rats were randomly divided into 7 groups: control group, model group, and 5 treatment groups, including soothing Liver (Gan) recipe group, invigorating Spleen (Pi) recipe group, dispelling dampness recipe group, promoting blood recipe group, and complex recipe group. Rats in the control group were fed with normal food and distilled water by gastric perfusion, while rats in the model group were fed with high-fat food and distilled spirits by gastric perfusion. Rats in the 5 treatment groups were fed with high-fat food and corresponding recipes by gastric perfusion. Twelve weeks later, all rats were sacrificed and liver tissues were stained for pathohistological observation. Kupffer cells were isolated from livers of rats to evaluate JNK and phospho-JNK expressions by Western blotting.

RESULTSThe grade of hepatic steatosis was higher in the model group than the control group (P<0.05). Compared with the model group, the grade of fatty degeneration in soothing Liver recipe group and invigorating Spleen recipe group were significantly ameliorated (P<0.05). Expressions of JNK and phospho-JNK in Kupffer cells were significantly higher in the model group than those in the control group (P<0.05, P<0.01). Compared with the model group, expressions of JNK in all treatment groups decreased, especially in invigorating Spleen recipe group and promoting blood recipe group (P<0.05). Compared with the model group, expressions of phospho-JNK in all treatment groups declined significantly (P<0.01), especially in soothing Live recipe group and invigorating Spleen recipe group.

CONCLUSIONSThe high expressions of JNK and phospho-JNK in Kupffer cells might play an important role in the pathogenesis of fatty liver disease in rats. The recipes of CM, especially invigorating Spleen recipe and soothing Liver recipe, might protect liver against injury by reducing the total JNK protein content and inhibiting the activation of JNK protein in Kupffer cells of fatty liver model rats, which showed beneficial effects on fatty liver disease.

OBJECTIVETo observe the effects of Nourishing yin clearing heat ([Chinese characters: see text]) Chinese herbal medicine on vascular endothelial growth factor (VEGF) in growth retardation induced by Decamethasone and observe its mechanisms.

METHODSThirty one-month-old New Zealand white rabbits were randomly divided into normal group, dexamethasone-treated group and Nourishing yin clearing heat ([Chinese characters: see text]) Chinese herbal medicine-treated group. The rabbits in dexamethasone group and Nourishing yin clearing heat ([Chinese characters: see text]) Chinese herbal medicine-treated group received dexamethasone (5 mg/kg x d). The rabbits were sacrificed at the 6th and 12th week after administration, and then rabbit tibia articular was removed. (1) Using TUNEL stain to detect apoptotic index. (2) Using immunohistochemical stain to detect the positive index of the expression of vascular endothelial growth factor (VEGF) in the epiphyseal cartilage of growth. (3) Using fluorescent quantitative PCR to detect the expression intensity of VEGF mRNA in each group.

RESULTSAt the 6th and 12th week after administration, there were significant difference in apoptotic index and cell proliferation index between dexamethasone group and normal group (P<0.01, dexamethasone group more than normal group). Immunohistochemical stain and fluorescent quantitative PCR indicated that the expression of VEGF and VEGF mRNA in dexamethasone group was significantly decreased as compared with that in normal group (P<0.01), and also obviously lower than Chinese herbal medicine-treated group (P<0.01).

CONCLUSIONVEGF has 2. an important role during the growth retardation induced by Dexamethasone. Nourishing yin clearing heat ([Chinese characters: see text]) Chinese herbal medicine can reduce the growth retardation induced by Dexamethasone through increasing the VEGF expression in growth plate chondrocytes and then increase angiogenesis.

OBJECTIVETo review the long-term clinical effect of composite transplantation of allogeneic acellular dermal matrix (ADM) and split thickness skin autograft (STSG).

METHODSNineteen patients with 34 wounds transplanted with allogeneic ADM combined with STSG who were hospitalized from March 2001 to October 2008 were enrolled as composite transplantation group (CT). Another 9 patients with 11 wounds transplanted with STSG admitted within the same time frame were enrolled as control group (C). All patients were followed up for longer than 2 years. Color, evenness, texture, contracture, sensation, and complications of transplanted skin were assessed using a modified Manchester Scar Scale (1-4 scores, the higher the score, the poorer the situation). The scar formation on skin donor sites was assessed by the Vancouver Scar Scale. Patients' degree of satisfaction and health status during the transplantation period were investigated in the form of questionnaire. The skin tissue structure of 4 patients was observed with histological method. The joint range of motion was assessed by the neutral position before and after operation and at follow-up. Data were processed with nonparametric test, chi-square test or t test.

RESULTS(1) The evenness, contracture, and texture of transplanted skin in CT group scored (1.6 ± 0.5), (1.8 ± 0.8), and (1.5 ± 0.8), respectively, which were significantly lower than those in C group [(2.0 ± 0.7), (2.2 ± 0.9), and (2.3 ± 0.7), with Z value respectively -2.058, -2.220, -2.323, P values all below 0.05]. Scores of color, sensation, and complications of transplanted skin in two groups were close to each other (with Z value respectively -0.628, -0.428, -2.520, P values all above 0.05). (2) Mild scar formation was observed in one of the skin donor sites in CT group. (3) Information as obtained from questionnaire showed no statistical difference between two groups in pinching, itching, and satisfaction degree (with χ(2) value respectively 0.187, 0.019, 2.628, P values all above 0.05). (4) Nerve fibers were seen in hand tissue 2 years after operation. ADM did not induce severe inflammatory responses in the site of grafting. (5) Eleven joints in CT group recovered or improved in function; while the other two joints required secondary surgery. Obvious contracture was observed in the two joints in C group.

CONCLUSIONSAllogeneic ADM combined with STSG transplantation prevents scar contracture and has obvious effect in improving function and appearance. There is no problem in regard to safety for its existence in either adult or children.

Objective: To analyze the effect of acupuncture versus hormone replacement therapy (HRT) for premature ovarian insufficiency (POI). Methods: China National Knowledge Infrastructure (CNKI), Wanfang Academic Journal Full-text Database (Wanfang), Chongqing VIP Database (CQVIP), China Biology Medicine Disc (CBM), Web of Science, Cochrane Library, PubMed, and Excerpta Medica Database (EMBASE) were searched up to January 31st, 2019 to identify randomized controlled trials (RCTs) evaluating the effect of acupuncture for POI. The primary outcome was the level of basal serum follicle- stimulating hormone (FSH). Secondary outcomes included serum levels of luteinizing hormone (LH), estradiol (E2) and anti-Müllerian hormone (AMH). Two authors extracted data independently and assessed the risk of bias and the methodological quality using the Cochrane's tool. Meta-analysis was conducted by RevMan version 5.3. Results: Eight eligible RCTs with a total of 496 POI patients were included in the meta-analysis. The pooled results showed that there was a significant reduction in the basal serum FSH level (MD=-5.82, 95％CI:-9.76 to -1.87, I2=82％, P=0.004) and a remarkable elevation in the basal E2 level (SMD=0.93, 95％CI: 0.34 to 1.52, I2=88％, P=0.002) in the acupuncture group when compared with the control. Subgroup analysis showed that compared with HRT, a significant decrease in the FSH level was observed in both acupuncture alone (MD=-4.53, 95％CI:-8.96 to -0.10, I2=73％, P=0.04) and acupuncture plus HRT (MD=-9.60, 95％CI:-17.60 to -1.61, I2=50％, P=0.02), while a remarkable elevation of E2 was only found in acupuncture plus HRT (SMD=1.43, 95％CI: 1.03 to 1.82, I2=0％, P<0.00001). There was no significant difference in the LH level between acupuncture and HRT (MD=-3.16, 95％CI:-9.41 to 3.10, I2=0％, P=0.32), only one trial reported AMH, and no significant difference was found between acupuncture and HRT. Conclusion: The present study indicated that acupuncture had an advantage over HRT in reducing serum FSH level and increasing serum E2 level in women with POI. However, evidence supporting the finding is limited due to the small sample size, potential methodological flaws and significant heterogeneity. Hence, this conclusion still needs to be verified by high-quality RCTs.

OBJECTIVEUsing polymerase chain reaction-reverse blot dot (PCR-RDB) technique to establish a new method for hepatitis C virus (HCV) genotyping and to study the distribution of HCV genotypes in Foshan area.

METHODSHCV primers and probes were designed in 5'-untranslated region (nt-1-nt-299) of HCV. HCV RNA in serum was isolated and purified, and its cDNA was obtained by reversed transcription. Nested PCR using biotin-labelled primers, was done. PCR products were hybridized with immobilized specific probes (genotype 1a to 3b) on Biodyne C membrane to genotype HCV by color development while adding POD and TMB. A certain judgment could be made according to the position of color reaction. The reliability of this new method was verified by sequencing. HCV RNA levels in serum were determined by real time fluorescent quantitative (FQ)-PCR. 60 FQ-PCR-positive HCV sera from Foshan area were genotyped using this assay.

RESULTSAll 60 sera could be successfully genotyped by PCR-RBD. 50 (83.3%) cases were found to be genotype 1b, 2 (3.3%) as genotype 1a and 2 (3.3%) as genotype 2a while 5 (8.0%) to be mixture of genotype 1a and 1b, and 1 (1.7%) to be mixture of genotypes 1b and 2a. No genotypes 2b, 3a and 3b were found. The results of PCR-RDB genotyping methods coincided with sequence analysis.

CONCLUSIONNewly established HCV genotyping system was proved to be sensitive, specific, precise and economic, thus suitable for clinical and epidemiologic studies. The results of HCV genotyping showed that genotype 1b was the predominant genotype in Foshan area.
