Objective To systematically review the effectiveness and safety of transcutaneous electricalnerve stimulation (TENS) on symptomatic diabetic neuropathy (DNP). Methods Electronic databases such asPUBMED, EMBASE, Cochrane Central Register of Controlled Trials, and Chinese Biomedical Database weresearched by using such mesh and text keywords as "TENS" and "diabetic neuropathy". Randomized controlled trials(RCTs) on the effect of TENS on symptomatic diabetic neuropathy were included. Studies were selected and availa-ble data was extracted independently by two reviewers. Meta-analysis was performed using RevMan 4.2.8 software.Results Three RCTs involving 78 patients were included in this study. Compared with sham-stimulation, TENStherapy significantly reduced the score in pain (SMD -2.35, 95% CI [-4.24, -0.46 ] ) and the score in numb-ness (WMD -0.18, 95% CI [-0.32, -0.05 ] ). Subgroup analysis shows that TENS therapy was associated with a significant reduction in the score of pain in both 4-week treatment duration ( SMD - 5.37, 95% CI [ - 6.97,- 3.77 ] ) and 6-week treatment duration ( SMD - 1.01, 95% CI [ - 2.01, - 0.01 ] ), but not 12-week treatmentduration (SMD - 1.65, 95% CI [ -4.02, 0.73 ] ). Conclusion TENS therapy is a promising and safe strategyfor treatment of symptomatic diabetic neuropathy. More studies are still warranted to accumulate the evidence of theeffect of TENS therapy on DNP.

OBJECTIVETo observe the effect of Uighur medicine gu-jing-mai-si-ha tablet (GJMSHT) for treatment of premature ejaculation (PE) and to explore part of its mechanism.
METHODSThe condition of patients was scored by related questionnaire, and the intravaginal ejaculation latency time (IELT) was observed before and after GJMSHT treatment, with the blood levels of nitric oxide (NO) and prostaglandin F2alpha (PGF2alpha) detected in PE patients as well. The results were compared with those in the control group.
RESULTSAfter treatment, the scores of PE and IELT, as well as the levels of NO and PGF2alpha, all increased significantly compared to those before treatment in the treated group (P<0.01), while in the control group, all the parameters were insignificantly changed (P>0.05). Therefore, the difference of these parameters between the two groups after treatment all showed statistical significance (P<0.01).
CONCLUSIONGJMSHT could treat PE effectively, its mechanism is possibly by strengthening the coordination of the related smooth muscles through increasing the blood levels of NO and PGF2alpha, and the endurance of patients to the cavitary effect of prostatico-urethral pressure, thus postponing the arrival of urgent ejaculatory feeling.

Objective To study phylogenies, epidemiology and genetic environment of CTX-M type of ESBLs produced by Escherichia coli and Klebsiella pneumoniae isolated from nine hospitals in Guangzhou. Methods The phylogenies of CTX-M type of ESBLs were analyzed by PCR Genetic environment of CTX-M-15 encoding gene (bla_(CTX-M-15)) were investigated by conjugation test and plasmid analysis. The clonal relationship of strains producing CTX-M-15 was determined by enterobacterial repetitive intergenic consensus PCR (ERIC-PCR). Results A total of 361 ESBLs-producing isolates of Escherichia coli and Klebsiella pneumoniae were collected. 67.3% of ESBLs strains were detected to produce CTX-M-type ESBLs, and the commonest genotypes in Escherichia coli and Klebsiella pneumoniae were CTX-M-14 (35.4% and 28.3%), CTX-M-15(21.5% and 26.1%) EBIC-PCR products of all CTX-M-15-producing strains show 39 strains of Escherichia coli were classified into 27 genotypes while 43 strains of Klebsiella pneumoniae were divided into 30 genotypes. Furthermore, the genotypes of CTX-M-55, CTX-M-19, CTX-M-27, with ceftazidime-hydrelyzing activity, were detected in this study. The great majority of bla_(CTX-M-15) genes were found to locate on a 65 000 bp-conjugative plasmid, and there was no blaTEM-1, bla_(OXA-1), blaDSA-1 or aac (6')-Ib-cr gene coexisted on the plasmid, ISEcp1-like insertion sequences, relative to mobilization of bla_(CTX-M-15) gene, were detected in all bla_(CTX-M-15) positive strains, and the distances between the end of ISEcp1-like insertion sequences and the start cedon of bla_(CTX-M-15) were equal, with 48 base pairs. Conclusion CTX-M-14 is still the most common genotype of ESBLs in Guangzhou, but high prevalence of CTX-M-15 ESBLs hydrolyzing ceftazidime already appears in south China.

Many epidemiologic and clinical studies have indicated that the frequency of breast cancer was lower in parous women than in nulliparous women. Moreover, the incidence of breast cancer has been reported to be lower in women with early childbirth than in women with late childbirth. To verify the effect of childbirth and the age at first childbirth on carcinogenesis and progression of breast cancer, we induced breast cancer by 7,12-dimethylbenanthracene (DMBA) in 120 female Sprague-Dawley (SD) rats, and divided them into control or experimental (DMBA-treated) nulliparous, early childbirth, and late childbirth groups to observe the incidence, latency, and size of breast cancer. Argyrophilic nucleolar organizer regions (AgNOR) count and the expression of C-erbB-2, proliferating cell nuclear antigen (PCNA), Ki-67, and minichromosome maintenance protein 2 (MCM2) in breast cancer tissues were detected by immunohistochemistry. The breast cancer incidences were 95.0%, 16.7%, and 58.8% in the experimental nulliparous, early childbirth, and late childbirth groups, respectively (all P < 0.05). Between any two of these groups, the latency was significantly different, but tumor size was similar. AgNOR count and the expression of C-erbB-2, PCNA, Ki-67, and MCM2 were significantly higher in the experimental nulliparous group than in the experimental early or late childbirth groups (P < 0.05), but no significant differences were observed between the latter two groups. Taken together, the results suggest that childbirth, especially early childbirth, can reduce the incidence and postpone the onset of DMBA-induced breast cancer.

Objective: To observe the clinical efficacy of Jinlida (JLD) granules and Tongxinluo (TXL) capsules on type 2 diabetic kidney disease (DKD) under the guidance of vessel collateral theory. Method: A total of 120 patients with type 2 DKD, were randomly divided into 2 groups:the normal control group (60 cases) and the treatment group (60 cases). The patients in normal control group were treated with dietary control and hyperglycemia control. Based on treatment in control group, patients in treatment group were additionally treated with JLD granules (1 bag, tid), and TXL capsules (4 capsules, tid). The treatment was lasted for 12 weeks. The clinical efficacy, traditional Chinese medicine(TCM) syndrome scores were observed and compared before and after treatment. At the same time, the levels of glucose metabolism indexes including fasting blood glucose (FBG),postprandial 2 h plasma glucose (2 hPG), glycosylated hemoglobin (HbA1c) and the insulin resistance (IR); the levels of lipid metabolism indexes including total cholesterol(TC),triglyceride (TG), low-density lipoprotein cholesterol (LDL-C) and the high-density lipoprotein cholesterol (HDL-C); the levels of renal function indexes including urinary albumin excretion rate (UAER) and serum creatinine (SCr); as well as nailfold microcirculation were detected and compared. Result: ①The total effective rate was 80.0% in treatment group, significantly higher than 61.67% in the normal control group (P<0.05). ②The improvement in TCM syndrome scores of the treatment group was better than that of the control group, and the difference was statistically significant (P<0.05). ③After treatment, the treatment group showed no significant difference with the control group in glucose metabolism indexes FBG, 2 hPG and HbA1c, but HOMA-IR improvement was better than that of control group (P<0.05). Lipid metabolism indexes TG, TC and LDL-C were significantly decreased (P<0.05), and HDL-C was increased in both groups (P<0.05). The improvement of renal function indexes SCr, UAER and urine Uβ2-MG in treatment group was significantly obvious than that in the control group (P<0.05). The nailfold microcirculation results showed that the microcirculation improvement in treatment group was better than that of control group (P<0.05). Conclusion: Tongxinluo combined with Jinlida can improve the clinical symptoms of patients with type 2 diabetic nephropathy and reduce urinary trace albumin, and its mechanism may be related to lowering glucose, regulating lipid metabolism and improving microcirculation.

Objective:
To investigate the inhibitory effect of AKR1B10 inhibitor combined with sorafenib on hepatocellular carcinoma (HCC) xenograft growth.
Methods:
HepG2 xenograft model was established in nude mice. The mice were then randomly divided into four groups: control group, epalrestat monotherapy group, sorafenib monotherapy group and combination treatment group. Tumor volume, tumor weight, T/C ratio and the change in body weight of nude mice in each group were compared to evaluate the curative effect. Immunohistochemistry staining was used to detect the expression of Ki-67 in tumor tissues to evaluate the proliferation status of tumor cells. One-way analysis of variance was used to compare the differences between the groups. Student’s t-test was used to test means of two groups and chi-square test was used for multiple samples.
Results:
The differences of the grafted tumor volume before and after treatment between the control group, epalrestat group, sorafenib group and combined therapy group was 238.940 ± 39.813, 124.991 ± 84.670, -26.111 ± 11.518, and -54.072 ± 17.673(mm3), respectively, (

Objective:Aldo-keto reductase family 1 member B10 (AKR1B10) pathogenesis, early diagnosis and prognosis are closely related with hepatoma. Therefore, this study explores the effect and mechanism of AKR1B10 on cell cycle in hepatoma cells.Methods:HepG2 cells were infected with lentivirus LV-AKR1B10-shRNA or treated with epalrestat, an AKR1B10 inhibitor. The expression level of AKR1B10 was detected by Western blot assay and real-time fluorescence quantitative PCR (RT-qPCR). Decreased AKR1B10 activity was detected by reduced coenzyme II (NADPH) absorbance at 340 nm. The low expression of AKR1B10 and the effect of different concentrations of epalrestat on cell proliferation and cell cycle were detected by CCK-8 method and flow cytometry. The protein expression levels of p-rb, cyclin D1, E1, p27 in HepG2 cells were detected by Western blot. The mean of the two samples was tested using independent sample t-test.Results:AKR1B10 expression level in hepatoma cells was significantly increased compared to normal liver cells, and the relative expression level of AKR1B10 protein in HepG2 cells was 6.71 ± 1.11 ( P = 0.012). Epalrestat was significantly inhibited with the enzymatic activity of AKR1B10 in a dose-dependent manner. AKR1B10 gene in HepG2 cells was effectively silenced. HepG2 cells treated with different concentrations of epalrestat (AKR1B10 inhibitor) for 24, 48 and 72 h had inhibited cell proliferation, promoted G0/G1 cell cycle arrest, reduced the expression of p-Rb, cyclin D1, and cyclin E1 and increased the expression of cyclin dependent kinase inhibitor p27 expression. Conclusion:AKR1B10 inhibitory expression and activity can promote G0/G1 cell cycle arrest in HepG2 cells through the p27 / p-Rb pathway.
