Objective To observe the clinical efficacy of electroacupuncture in treating herpes zoster.Method Ninety patients with herpes zoster were randomized into treatment group 1, treatment group 2, and a control group, 30 cases in each group. Treatment group 1 was intervened by surround needling at Ashi points (deep needling, by 33 mm) plus electroacupuncture; treatment group 2 was by surround needling at Ashi points (superficial needling by 16 mm) plus electroacupuncture; the control group was by oral administration of Valacyclovir Hydrochloride tablets plus Vitamin B1. After 10-day treatment, the blister-breaking time, crust-forming time, and the time of falling-off of the crust, and Visual Analogue Scale (VAS) were observed, and the clinical efficacies were compared.Result The recovery rate and total effective rate were respectively 73.3% and 93.3% in treatment group 1, versus 46.7% and 86.7% in treatment group 2, and 33.3% and 63.3% in the control group. The recovery rate of treatment group 1 was significantly different from that of treatment group 2 and the control group (P<0.01,P<0.05). The total effective rates of treatment group 1 and 2 were both significantly different from that of the control group (P<0.01,P<0.05). The blister-breaking time, crust-forming time, and crust falling-off time of treatment group 1 were significantly different from that of treatment group 2 and the control group (P<0.01,P<0.05). The crust-forming time and falling-off time of treatment group 2 were significantly different from that of the control group (P<0.05). The VAS scores were markedly changed after the intervention in the three groups (P<0.01). After the treatment, the VAS scores of treatment group 1 and 2 were significantly different from that of the control group (P<0.01). The VAS score of treatment group 1 was markedly different from that of treatment group 2 after the treatment (P<0.05).Conclusion Electroacupuncture is an effective method in treating herpes zoster, while deep surround needling at Ashi points plus electroacupuncture can effectively inhibit the development of blisters, promote crust-forming, release the neural pain, and reduce the incidence of postherpetic neuralgia.

Objective To evaluate microdeletion of DAZ gene on the Y chromosome in patients suffering from idiopathic azoospermia or severe oligozoospermia.Methods The four sites including SY154,SY155,SY254,SY255 and SRY regions of Y chromosome in 38 cases of idiopathic azoospermia and severe oligozoospermia were detected by STS-PCR.Results Six cases of microdeletion of DAZ genes were found in 38 patiens,microdeletion rate was 15.8%.Five cases from 30 patiens suffering from idiopathic azoospermia,microdeletion rate was 16.7%.One case from 8 patients suffering from severe oligozoospermia had microdeletion.The microdeletion rate was 12.5%.Conclusions The microdeletion of DAZ gene is a major cause of idiopathic azoospermia and severe oligozoospermia leading to male infertility.Therefore,DAZ gene should be detected and PGD should be done prior to ICSI for the patients suffering from idiopathic azoospermia and severe oligozoospermia.

Objective:To observe the effect of abdominal electroacupuncture(EA)on intestinal function in patients with constipation after stroke. Methods:A total of 100 patients with post-stroke constipation were divided into an observation group and a control group by the random number table method,with 50 cases in each group.The control group was treated with oral lactulose,10 mL each time,3 times a day,for 2 consecutive weeks.The observation group was treated with additional abdominal EA at Tianshu(ST25),Fushe(SP13),and Daheng(SP15)on the basis of oral lactulose,30 min for needle retention each time,once a day,for 2 consecutive weeks.The total effective rate after treatment,constipation symptom score,the score of patient assessment of constipation quality of life scale(PAC-QOL),serum motilin(MTL)level,and the score of mini-mental state examination(MMSE)were compared between the two groups. Results:After 2 weeks of treatment,the total effective rate was 93.5%in the observation group and 76.1%in the control group,and the difference between the two groups was statistically significant(P<0.05).The constipation symptom score,PAC-QOL score,MMSE score,and MTL level changed significantly after treatment in both groups(P<0.05).After treatment,the constipation symptom score and PAC-QOL score in the observation group were lower than those in the control group,while the MMSE score and MLT level were higher than those in the control group,and the differences between the two groups were statistically significant(P<0.05). Conclusion:On the basis of oral lactulose,EA at abdominal points can significantly improve the intestinal and cognitive function of stroke patients simultaneously.

Objective:To explore the effect of adipose derived mesenchymal stem cells to regulate the differentiation of macrophage RAW264.7.Methods:First,we used RAW264.7 cells to simulate macrophage and induced them to M 1 macrophage with lipopolysaccharide ( LPS,1 μg/ml) .Then we cultured these RAW264.7 cells in culture mediums which were previously used to culture adipose derived mesenchymal stem cells to imitate the transplantation of ADMSC .Last,the mRNA relative expression of IL-10, IGF-1,Arg-1,TNF-α,FIZZ1,SPHK-1 was detected by real-time PCR.The protein expression of IL-12 p40,IL-27 Rα,IL-10 was detected by Western blot.Results:After been cultured in ADMSCCM and induced by LPS ,M1 markers (TNF-αmRNA,IL-12 p40;P<0.05) of the RAW264.7 cells declined while M2 markers (IGF-1 mRNA,IL-10 mRNA,IL-10;P<0.05) rose.Conclusion: ADMSC can secrete soluble cytokines to induce the RAW264.7 cell,which have been induced to the M1 macrophages,to differentiate towards M2 macrophages.

Objective:To investigate the effect of polypeptide N-acetylgalactosaminaminyltransferase 2 (GALNT2) on the proliferation and apoptosis of human retinal vascular endothelial cells (HRCECs) cultured in high glucose and its possible mechanism.Methods:The small hairpin RNA (shRNA) targeting GALNT2 gene was constructed to interfere with the lentiviral vector and infect HRCECs.HRCECs were divided into blank control group, model group, NC-shGALNT2 group and shGALNT2 group, which were cultured in medium containing 5.5 mmol/L glucose, 25 mmol/L glucose, shGALNT2 negative control virus 25 mmol/L glucose and shGALNT2 knockdown virus 25 mmol/L glucose for 24 hours, respectively.The relative expression of GALNT2 mRNA in the four groups was detected by real-time fluorescence quantitative PCR.The relative expression levels of GALNT2, epidermal growth factor (EGF), EGF receptor (EGFR) and phosphorylated EGFR (p-EGFR) were detected by Western blot.The proliferative values of HRCECs were detected by cell counting kit-8 method.The apoptosis rate of different groups was detected by flow cytometry. Results:The relative expression levels of GALNT2 mRNA and protein were significantly higher in model group than in blank control group, and were significantly lower in shGALNT2 group than in blank control group (all at P<0.05). The cell proliferation value was significantly lower in model group than in blank control group, and was significantly higher in shGALNT2 than in model group and NC-shGALNT2 group (all at P<0.05). The apoptosis rates of blank control group, model group, NC-shGALNT2 group and shGALNT2 group were (4.73±0.26)%, (8.66±0.25)%, (9.26±1.12)% and (5.47±0.18)%, respectively, with a significant overall difference ( F=342.921, P<0.001). The apoptosis rate was significantly higher in model group than in blank control group, and was significantly lower in shGALNT2 group than in model group and NC-shGALNT2 group (all at P<0.05). The relative expression level of EGFR protein was significantly higher and the relative expression level of p-EGFR protein was significantly lower in model group than in blank control group (all at P<0.05). The relative expression of p-EGFR protein was significantly higher in shGALNT2 group than in model group (all at P<0.05). Conclusions:Knocking down GALNT2 can improve the proliferative ability of HRCECs under high glucose culture and reduce apoptosis, which may be related to the activation of EGFR signaling pathway.
