Objective To evaluate the efficacy of tolterodine in preventing bladder spasm during the operation to BPH.Methods One hundred and twelve cases of BPH patients were randomized to two groups:56 cases in one group were prescribed tolterodine 4-5 d before operation and 3-4 d after operation (2 mg twice daily),another 56 cases did not take any anti-spasm drugs.The bladder spasm occurring or not,frequency and continuing time of bladder were evaluated and recorded.Results In the controlling group:the non bladder spasm in 12.5% (7/56),mild bladder spasm in 14.3% (8/56),severe bladder spasm in 73.3% (41/56),In the treatment group:non bladder spasm in 87.5% (49/ 56),mild bladder spasm in 8.9% (5/56),severe bladder spasm in 3.6% (2/56).There was signifi-cant difference between the 2 groups (P<0.001).Conclusion Tolterodine could alleviate bladder spasm around the operation to BPH.

Objective A meta-analysis was conducted to figure out the effects of anesthetic methods on postoperative myocardial infarction in noncardiac surgery patients.Methods We searched PubMed, Embase, Ovid, Cochrane Library, Google scholar, CNKI, Wang-fang data and VIP Database (by September 2016) to identify relevant studies that focused on the effect of intrathecal blockade on postoperative myocardial infarction and mortality in non-cardiac surgery.Meta-analysis was performed using software of RevMan 5.3.Results A total of 21 859 patients from 10 RCTs were enrolled.The meta-analysis showed that there were no differences in myocardial infarction within 7 postoperative days (OR=0.44, 95%CI 0.13-1.46, P=0.18) or 30 days (OR=1.49, 95%CI 0.89-2.49, P=0.13) and all-cause mortality (OR=1.26, 95%CI 0.84-1.88, P=0.26) between epidural anesthesia combined with general anesthesia and general anesthesia.Furthermore, there were no differences in myocardial infarction within postoperative 7 days (OR=1.14, 95%CI 0.31-4.17, P=0.84) and all-cause mortality within postoperative 30 days (OR=0.88, 95%CI 0.43-1.79, P=0.73) between spinal anesthesia alone and general anesthesia alone.Conclusion Intrathecal blockade cannot affect the incidence of myocardial infarction and mortality in high-risk cardiac patients undergoing intermediate or high-risk non-cardiac surgery.

OBJECTIVETo summarize and analyze rules for acupoint selection and prescription composition in clinical literature regarding acupuncture for polycystic ovary syndrome (PCOS).

METHODSCHKD, VIP and Wan-fang databases were retrieved. The clinical literature data included in the study was collected. The descriptive statistical analysis was conducted on the main acupoints, main meridians of main acupoints, distribution of main acupoints, application of special points and rules for acupoint composition.

RESULTSFifty-two articles were included, involving 55 main acupoints with a total frequency of 375. The most frequent acupoints of acupuncture for PCOS were Sanyinjiao (SP 6), Guanyuan (CV 4), Zigong (EX-CA 1), Zhongji (CV 3) and Qihai (CV 6). The meridians of main acupoitns were conception vessel, spleen meridian of foot-taiyin and stomach meridian of foot-yangming. The main acupoints were distributed in the lower abdomen, lower limbs and back. In the special points, the use of front-mu points, five-shu points and back-shu points was more frequent. The prescription was usually consisted of 5 to 7 acupoints, (6. 9 ± 3. 6) acupoints in average.

CONCLUSIONIn the modern treatment of acupuncture for PCOS, Sanyinjiao (SP 6), Guanyuan (CV 4), Zigong (EX-CA 1), Zhongii (CV 3) and Qihai (CV 6) are most used. With the theories of meridian and zang-fu as essential references, the acupoint selection is based on disease differentiation and meridian circulation. Additionally, the methods for selecting the adjacent points and the distant points are adopted.

Objective To explore the integrity of white matter changes in patients with vascular mild cognitive impairment (VaMCI)based Leukoaraiosis.Methods The patients which appeared white matter hyperintensities in subcortical were performed psychological testing,then 48 VaMCI patients and 18 without cognitive impairment volunteers(NC)were choosed and performed DTI scanning,to determine the white matter’s values of FA and ADC in the following bilaterally symmetrical regions of interest(ROI):entorhinal cortex lobe,hippocampal vault,anterior of corpus callosum,posterior of corpus callosum,inferior frontal lobe,superior temporal lobe and angular gyrus of occipital lobe. Then the differences of the data of DTI between two groups and the relevance between neuropsychological score and DTI’s data were analysed.Results ADC values were significantly higher of VaMCI group in the left inferior frontal lobe,left anterior of corpus callo-sum,left hippocampus vault and right angular gyrus compared with NC group(P <0.05),and in the left hippocampus ADC values and MoCA scores was negatively correlated(r=-0.34,P =0.02).There was no significant difference of FA values between groups. Conclusion The ADC values in many cognitive related areas was reduced in VaMCI patients.

Objective To evaluate the effects of limited fluid resuscitation on systemic inflammatory responses in rats with traumatic hemorrhagic shock through comparing with unlimited fluid resuscitation.Methods Sixty pathogen-free male Sprague-Dawley rats,aged 2-3 months,weighing 250-290 g,were randomly divided into 6 groups (n =10 each) using a random number table:sham operation group (group S),no fluid resuscitation group (group NF),unlimited fluid resuscitation group (group ULF),limited crystalloid fluid resuscitation group (group LR),and limited colloid fluid resuscitation groups (group LSG and group LHES).Traumatic uncontrolled hemorrhagic shock was induced by withdrawal of blood from the femoral artery at 2.5 mL/100 g over a 20-minute period,followed by tail amputation at 10 min after the end of blood withdrawal.At 10 min after the end of blood withdrawal,fluid resuscitation was performed.Lactated Ringer's solution (ULF and LR groups),4 ％ succinylated gelatin (group LSG),or 6 ％ hydroxyethyl starch 130/0.4 (group LHES) was infused intravenously.The initial infusion rate was 2 ml · kg-1 · min-1.The target MAP was maintained at 50 mm Hg in rats with limited fluid resuscitation,while at 80 mm Hg in rats with unlimited fluid resuscitation.After 60 min of fluid resuscitation,bleeding in the tail was stopped by ligation and fluid infusion was replaced with blood resuscitation.After 60 min of blood resuscitation,180 main of observation was started.At 10 min after catheterization of the femoral artery and vein (T0),10 min after the end of blood withdrawal (T1),the end of fluid resuscitation (T2),the end of blood resuscitation (T3),and the end of observation (T4),arterial blood samples were collected to measure hematocrit (Hct)and concentrations of plasma tumor necrosis factor-alpha (TNF-α),interleukin (IL)-6,and IL-10.Blood samples were collected from the femoral artery at T2 for determination of the expression of Toll-like receptor 4 (TLR4) and myeloid differentiation factor 88 (MyD88) and activity of nuclear factor-kappaB (NF-κB) in monocytes.The amount of blood loss from the tail and volume of fluid infused were also recorded.Another 120 Sprague-Dawley rats were randomly divided into 6 groups (n =20 each) and resuscitation was performed according to the method previously described.The rats were observed for 72 h survival rate.Results Compared with group S,Hct was significantly decreased,the concentrations of plasma TNF-α,IL-6,and IL-10 and activity of NF-κB were increased,and the expression of TLR4,and MyD88 in monocytes was up-regulated in the other groups (P ＜ 0.05).Compared with group NF,the concentrations of plasma TNF-α and IL-6 and NF-κB activity were significantly increased,and the concentration of plasma IL-10 and Hct were decreased,and the expression of TLR4 and MyD88 in monocytes was up-regulated in ULF,LR and LSG groups,and the concentrations of plasma TNF-α and IL-6 were significantly increased,the concentration of plasma IL-10 and Hct were decreased in group LHES (P ＜ 0.05).Compared with group ULF,the concentrations of plasma TNF-α and IL-6 and NF-κB activity were significantly decreased,the concentration of plasma IL-10 and Hct were increased,the survival rate was higher,the expression of TLR4 and MyD88 in monocytes was down-regulated,and the amount of blood loss from the tail was decreased and the volume of fluid infused was reduced in LSG,LHES and LR groups (P ＜ 0.05).Compared with group LR,the concentrations of plasma TNF-α and IL-6 and NF-κB activity were significantly decreased and the expression of TLR4 and MyD88 in monocytes was down-regulated (P ＜ 0.05),and no significant change was found in the concentration of plasma IL-10 in group LHES (P ＞ 0.05),and the volume of fluid infused was reduced and the survival rate was increased (P ＜ 0.05),and no significant change was found in the amount of blood loss from the tail in LSG and LH-ES groups (P ＞ 0.05).Conclusion Compared with unlimited fluid resuscitation,limited fluid resuscitation exerts less effect on systemic inflammatory responses in rats with traumatic hemorrhagic shock,especially when resuscitation with 6％ hydroxyethyl starch 130/0.4 is performed,and inhibition of TLR4/NF-κB signaling pathway is involved in the mechanism.

The anti-hepatitis B virus (HBV) effects and its mechanisms of the ethanol extracts of Hypericum perforatum L. (EHP) in vitro were explored. HepG2 2.2.15 cells, a stable HBV-producing cell line, were cultured as the model system to observe the anti-HBV effect. The viral antigens of cellular secretion, HBsAg and HBeAg, were determined by enzyme linked immunosorbent assay (ELISA). The quantity of HBV-DNA released in the supernatant was assayed by real-time PCR. In order to understand the mechanisms of the suppression of HBV replication, all HBV promoters (Cp, Xp, S1p, S2p and Fp) with luciferase reporter gene were transfected into HepG2 cells respectively. Then the activities of viral promoters were examined by luciferase reporter assay. It was found EHP effectively suppressed the secretion of HBsAg and HBeAg from HepG2 2.2.15 cells in a dose-dependent manner, as well as the extracellular HBV DNA. And EHP could selectively inhibit the activity of HBV promoter Fp. Our data suggest that EHP exerts anti-HBV effects via inhibition of HBV transcription, which helps to elucidate the mechanism underlying the potential therapeutic value of EHP.

This study investigated the influence of silencing TRAF6 with shRNA on lipopolysaccharide (LPS)/toll-like receptor (TLR)-4 signaling pathway in vitro. Four plasmids (pGCsi-TRAF6-shRNA1, 2, 3, 4) containing different shRNA sequences were designed and synthesized. The proliferation of RAW264.7 cells after transfected with these plasmids was measured by MTT assay. Inflammatory cellular models were established by LPS stimulation. Levels of TNF-alpha, IL-1beta and TGF-beta1 in the supernatants, mRNA expressions of TRAF6, IL-6 and COX-2, protein expression of TRAF6 and translocation of NF-kappaB were assayed by ELISA, real-time quantitative PCR and Western blotting, respectively. The results showed that the TRAF6 gene knockdown by RNAi hardly inhibited the proliferation of RAW264.7 cells within 72 h. The mRNA and protein expression of TRAF6 was lower in the TRAF6-shRNA1, 2 groups than in the TRAF6-shRNA3, 4 groups. Therefore, pGCsi-TRAF6-shRNA1, 2 were selected for the subsequent experiments. Our results still showed that pGCsi-TRAF6-shRNA1, 2 could significantly reduce the production of pro-inflammatory cytokines and mediators including TNF-alpha, IL-1beta, IL-6 and COX-2, and inhibit NF-kappaB nuclear translocation. Moreover, pGCsi-TRAF6-shRNA1, 2 could suppress the release of TGF-beta1 at the protein level. It was concluded that the recombinant plasmid pTRAF6-shRNA can, to some extent, inhibit inflammatory response stimulated by LPS at the initial phase. TRAF6 may become the potential therapeutic target of many inflammation-related diseases.

In this study, the anti-HBV effects of tea polyphenols (TP) were examined. After cells were exposed to TP for 3, 6, 9 days, amounts of HBsAg, HBeAg and HBV-DNA released into the supernatant of the cultured HepG2 2.2.15 cells were detected. TP, to some extent, inhibited the secretion of HBsAg and strongly suppressed the secretion of HBeAg in a dose-dependent (P<0.01) and time-dependent manner, with 50% maximal inhibitory concentration (IC50) value being 7.34 microg/mL on the 9th day, but the time-dependence was not significant (P=0.051). Expression of HBV-DNA in the supernatant of the cell culture also was significantly decreased in a dose-dependent fashion (P<0.01). The IC50 of TP in inhibiting HBV DNA was 2.54 microg/mL. It concluded that TP possessed potential anti-HBV effects and may be used as a treatment alternative for HBV infection.

Conclusion CALHM1, ABCA7, A2M and CLU, etc., have a certain correlation with AD, which provide theoretical basis for further research of AD genics and clinical treatment.

Genetic factors play an important role in the development of Alzheimer's disease (AD). This article mainly introduced some genes, which have been reported in recent years, predisposing to different aspects of AD. The occurrence and progress of the late onset Al-zheimer's disease (LOAD) can be better understood through further study of the susceptibility loci, especially by using the pathway analysis, and the important hub genes can be found so as to provide targets for clinical prevention, diagnosis and treatment. Due to the dispersion of genetic variant information, it needs detailed literature, online search and some bioinformatics methods to analyze the causative genes and signaling pathways related to LOAD. 3 databases were took as recourses, and they were analyzed with multi-means and multi-ways of analy-sis and data mining methods, in order to provide theoretical basis for further study and clinical treatment of AD genetics.
