Objective To compare the effect of endoscopic nasobiliary drainage (ENBD) and endoscopic retrograde biliary drainage (ERBD) on intestinal mucosal barrier function of patients with obstructive jaundice in clinical practice.Methods Forty patients with significant jaundice due to obstructive disorders of biliary tract and 20 health volunteers as controls were recruited.At the baseline,serum diamine oxidase (DAO) was measured with ultraviolet spectrophotometer,while endotoxin and tumor necrosis factorα (TNF-α) were determined with endotoxin detector and enzyme-linked immunosorbent assay (ELISA)kits,respectively.Forty patients were then divided randomly into ENBD and ERBD groups (n =20 patients per group).Dynamic changes in serum DAO,endotoxin and TNF-α were observed postoperatively.Results In the patients with obstruction of biliary tract,higher serum bilirubin,γ-glutamyl transpeptidas (γ-GT),alkaline phosphatase (ALP),DAO,endotoxin,and TNF-α were found preoperatively relative to those in health control (P ＜ 0.05).After operation,ERBD and ENBD had comparable effect on improving serum bilirubin,γ-GT and ALP,while serum DAO,endotoxin and TNF-α in each group were dramatically decreased.In day 1 after operation,there was no significant difference in serum DAO,endotoxin and TNF-α between two groups.However,in day 3 and 7 after operation,serum DAO,endotoxin and TNF-α in ENBD group were significantly higher than those in ERBD group (P ＜ 0.05).Conclusions It was suggested that ERBD and ENBD have comparable effects on removing obstruction of biliary tract and draining bile.However,ERBD might have greater benefits than ENBD in improving intestinal mucosal barrier function,and thus would be more beneficial in preventing systemic inflammatory response.

Objective To explore the therapeutic efficacy and safety of endoscopic sphincterotomy joint balloon dilatation in the treatment of common bile duct calculi in order to reduce the recent and long-term complications.Methods A total of 120 cases of patients with common bile duct calculi was grouped into three groups:endoscopic sphincterotomy joint balloon dilatation,endoscopic sphincterotomy (EST),and endoscopic papillo-sphincter balloon dilatation (EPBD).The operative efficacy of three groupsand the incidence of postoperative immediate and long-term complications were observed and compared.Results No difference was found in total stone-free rate among three groups.No significant difference was found in a stone-free rate and lithotripsy rate between endoscopic sphincterotomy joint balloon dilatation and EST groups (P ＞ 0.05),however,those parameters in the former two groups were better than EPBD group (P ＜ 0.05).The incidence of postoperative bleeding in the endoscopic sphincterotomy joint balloon dilatation group is lower than EST group.The incidence of postoperative pancreatitis in the endoscopic sphincterotomy joint balloon dilatation and EST groups was lower than the EPBD group(P ＜ 0.05).For the long-term complications,the incidence of reflux cholangitis in the endoscopic sphincterotomy joint balloon dilatation group was lower than the EST group (P ＜ 0.05).The recurrence rate of postoperative bile duct calculi in the endoscopic sphincterotomy joint balloon dilatation group was lower than the EST and EPBD groups.Conclusions For the endoscopic sphincterotomy joint balloon dilatation in the treatment of common bile duct calculi,its curative effect was the same as the EST,but better than EPBD; it had a lower incidence of immediate and long-term complications than EST and EPBD.

OBJECTIVE:To observe the clinical efficacy and safety of Shuanghuanglian oral liquid combined with cefuroxime axetil in the treatment of bacterial respiratory tract infection. METHODS:184 patients with bacterial respiratory tract infection were randomly divided into test group and control group. Test group was orally given 250 mg Cefuroxime axetil tablet,twice a day+20 ml Shuanghuanglian oral liquid,3 times a day. Control group was only given Cefuroxime axetil tablet (the same dosage as test group). The treatment course for 2 groups was 2 weeks. The cough duration,body temperature recovery time and runny nose disap-pearing time before and after treatment and bacterial clearance rate in 2 groups were observed,clinical efficacy and incidence of ad-verse reactions were recorded. RESULTS:After treatment,the total effective rate in test group was significantly higher than control group,cough duration,body temperature recovery time and runny nose disappearing time were significantly shorter than control group,the differences were statistically significant(P<0.05);and there were no significant differences in the bacterial clearance rate and incidence of adverse reactions(P>0.05). CONCLUSIONS:The efficacy of Shuanghuanglian oral liquid combined with ce-furoxime axetil is superior to cefuroxime axetil alone in the treatment of bacterial respiratory infections,with similar safety.

Objective To study the relationship between serum macrophage migration inhibitory factor (MIF) levels and clinical features in the patients with colorectal cancer. Methods Enzyme-linked immunosorbent assays was used to detect the concentration of MIF in sera of 75 patients with colorectal cancer (35 case with primary colorectal cancer and 40 cases with lymphnode metastasis of colorectal cancer) and 40 healthy controls. The relationship between serum MIF levels and clinical features was analyzed. Results Serum MIF was found to be significantly elevated in the patients with colorectal cancer(mean value 31.2ng/ml) compared with healthy subjects (mean value 13.6ng/ml) (P <0. 001). The levels of MIF in colorectal cancer were significantly correlated with advanced clinical progression pathology stages (P <0. 05) and lymph node metastasis (P < 0. 05). Conclusions Increased expression level of MIF in serum may promote the pathogenesis of colorectal cancer and M1F is closely associated with the stages and lymph node metastasis of colorectal cancer.

Objective To study the effects of ultraviolet(UV)radiation disinfection on purified wecter in water dis-penser.Methods The original structure of water dispenser was modified by installing additional UV lamps.The water samples were collected from the tap of the newly modified water dispenser simulated the practical status of water supply in indoor environment under the different conditions including different intensities of UV lamps and water flow rates.The total counts of bacteria of water samples were determined based on the Sanitary Standard for Bottled Purified Drinking water(GB17324-1998).Results The total counts of bacteria of water samples collected from the tap of the newly mod-ified water dispenser were below20cfu/ml,which was lower than those of control water sample(P

OBJECTIVETo explore the feasibility and safety of dexmedetomidine combined with remifentanil for lower eyelid blepharoplasty.

METHODS50 patients undergoing lower eyelid blepharoplasty ASA I - II were randomly divided into 2 groups (25 in each group) as observation group and control group. Dexmedetomidine (0.3 microg x kg(-1) x h(-1)) and remifentanil (0.05 microg x kg(-1) x min(-1)) were used in observation group. Local anesthesia by lidocaine (1%) combined with midazolam (0.04 mg/kg) intravenous sedation were used in control group. HR, mean arterial pressure (MAP), heart rate (HR), breathing rate (RR), pulse oxygen saturation (SpO2) change were monitored and recorded before and after the administration of the drug, as well as at the beginning of operation, during the operation, at the end of the operation, and 5 minutes after the operation. Patients sedation degree was evaluated by Ramsay. Operation time, recovery time, the incidence of adverse reactions, the satisfaction of patients and doctors were also recorded.

RESULTSPatients had no obvious difference of intraoperative MAP, RR, SpO2, operation time and postoperative recovery time between the two groups (P > 0.05). Compared with control group, HR during the operation were decreased significantly [(64.2 +/- 8.2) bpm, P < 0.05] in observation group. In control group, there were 18 cases of patients with agitation, but they endured the operation anyway. In observation group, 24 cases of patients underwent operation without agitation. The satisfaction of patients and the operation doctors (96%) in observation group were markedly higher than that in control group (P < 0.05).

CONCLUSIONDexmedetomidine combined with remifentanil is practical and safe. The effect of reducing HR should be noticed.

Objective To investigate the effect of liraglutide on the expression of NF-kappa B (NF-κB), tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6) in renal tissue of insulin resistance rats. Method The rats were divided into 4 groups, control group ,high fat group ,liraglutide low dose group [100 μg/(kg· d)], liraglutide high dose group[100 μg/(kg·d)]. Detection of serum creatinine and urea nitrogen by automatic biochemical analyzer, and 24 h urine micro albumin was determined by immunoassay. The protein concentration of serum NF-κB,TNF-α and IL-6 was measured by ELISA. The expression of NF-κB,TNF-α and IL-6 mRNA in renal tissues was determined by RT-PCR. Results Compared with the control group, the serum creatinine, blood urea nitrogen,urinary protein, and the expression of NF-κB, TNF-α and IL-6 were significantly higher in high fat group, respectively (P < 0.05). The glomerular basement membrance thickening and foot process fusion were seen under electron microscope. Liraglutide high dose intervention can significantly reduce these changes. Conclusions Liraglutide can inhibit the expression of NF-κB,TNF-α and IL-6 in renal tissues of high fat induced insulin resistance rats,in a concentration dependent manner, which possibly improve renal function.

Objective To develop a fluorescence signal activatable multifunctional molecular probe with theranostics function through combining ultrasmall gold nanorods(UGNRs) with fluorescein,and to evaluate its therapeutic effect on photothermal therapy (PTT) in breast cancer cells.Methods The UGNRs were synthesized by the one-pot seedless method,then the functionalized modification of UGNRs were conducted using cysteamine.Finally,the activatable ultrasmall gold nanorods (AUGNRs) were synthesized by amide condensation of —NH2 of cysteamine and —COOH of carboxylated fluorescein CyS.The cell uptake ability and GSH-mediated imaging ability of AUGNRs were studied using breast cancer 4T1 cells.4T1 cells co-cultured with AUGNRs were irradiated with 808 nm excitation light,and the PTT effects were assessed by MTT colorimetric staining and calcein-AM/PI staining.Results The AUGNRs were synthesized successfully,which could be uptaken by 4T1 cells quickly and efficiently,and could achieve intracellular glutathione (GSH) triggered fluorescence recovery.No obvious cytotoxicity of AUGNRs to 4T1 cells was observed in the co-cultivation.Moreover,obvious PTT effects could be induced by 808 nm laser,which could effectively kill 4T1 cancer cells.Conclusion The fluorescence signals of AUGNRs can be induced by intracellular GSH,and tumor cell destruction can be achieved by 808 laser-excitated PTT effects.

Objective To study the effect of rhodiola crenulata compound on serum corticosterone and myocardial glucocorticoid receptor ( GR) in rats exposed high sustained +Gz.Methods Seventy-two healthy SD rats were randomly divided into six groups: blank control group, stress control group, +10 Gz stress group and low, medium, high dose drug group, with twelve rats in each.20 mL/kg menstruum was fed to each rat once per day for 14 days.Low, medium and high dose drug group were fed with rhodiola crenulata compound at doses of 0.75 g/kg, 1.5 g/kg and 3.0 g/kg respectively, the other three groups were fed with equal volume saline.Rats were exposed to high +Gz in 15th day.The concentration of corticosterone in the serum of each group rats was detected with ELISA. Western blot was used to detect the expressions of GR in the myocardium of each group rats .Results The content of corticosterone was significantly elevated in +10Gz stress group, while the expression of GR in the myocardium was markedly declined (P <0.01,P <0.05).However, compound preconditioning could decrease concentration of corticosterone in the serum and enhance the expression of GR in the myocardium from rats after +10 Gz exposure. The corticosterone concentration of medium and high dose drug groups was significantly lower and the level of GR expression in the myocardium was significantly higher than that of +10 Gz stress group ( P <0.05 , P <0.01 ) . Conclusion Rhodiola crenulata compound preconditioning could regulate the concentration of corticosterone in the serum and the level of GR expression in the myocardium of the rats exposed +10 Gz, which may be related with its protective effect on high sustained +Gz-induced injury of myocardium.
