Objective To investigate the serum levels of fatty cytokines in hepatitis B patients with liver fibrosis.Methods Fifty six hepatitis B patients with liver fibrosis admitted in Wenzhou Central Hospital from April 2014 to March 2016 were recruited as case group and 65 healthy subjects as control group.Serum cytokines including omentin,leptin,adiponectin and visfatin were detected in both two groups and glutamyl endopeptidase (ALT),aspartate aminotransferase (AST) and hepatitis B virus DNA were detected in the case group.Liver biopsy was performed in the case group and histologic activity (HA) and histologic fibrosis (HF) stage were evaluated.Results The level of omentin in the case group was significantly higher than that in the control group [(358-119) vs.(305 ± 108) μg/L,t =2.236,P =0.037].Serum omentin,visceral fat hormone,leptin and adiponectin were not associated with liver function and HBV-DNA (P ＞0.05).There was no significant difference in adipocytokines levels between the low and high HA group (P ＞ 0.05).The level of omentin in high HF stage group was significantly higher than that in low HF stage group [(398 ± 130) vs.(292 ± 120) μg/L,t =2.648,P =0.009],while the other fatty cytokines did not show significantly differences between high and low HF groups (P ＞ 0.05).Conclusion Serum omentin level is elevated in hepatitis B patients with liver fibrosis and is associated with liver fibrosis severity.

Objective To assess the feasibility and effectiveness of percutaneous transluminal angioplasty (PTA)for the salvage of immature arteriovenous fistula (AVF) and to identify the incidence of arterial and venous puncture site spasm.Methods The medical records and radiological data of 88 patients with 112 interventional procedures for immature AVFs were retrospectively reviewed.Results The stenosis lesions were (2.0 ± 1.4) cm long.Technical success rate and clinical success rate were 80.4％ (78/97) and 92.8％ (90/97) for PTA via brachial artery,85.7％ (6/7) and 100％ (7/7) for PTA via vein,25％ (2/8) and 50％ (4/8) for PTA via both brachial artery and vein,respectively.Spasm of pure arterial PTA occurred in 2 patients (2.1％) and was mild and moderate.Spasm of pure venous PTA occurred in 2 patients (28.6％) and was both moderate.Spasm of combined arterial and venous PTA occurred in 3 patients (37.5％) and from being severe to completely occluded.By comparison,there were statistical differences of technical and clinical success rate (P =0.000,0.019 ; P =0.000,0.029),fistulas spasm rate was statistically significant different (P =0.000).Conclusions Endovascular therapy was effective in restoring the dysfunctional native AVFs,it was safer and more effective and with less sideeffects especially in selecting coronary balloon to treat patients without large phlebangioma and round fistulas.

Objective To summarize the experience of the nursing care of indwelling catheter thrombolysis for acute thrombosis in the arteriovenous fistula in eight hemodialysis patients.Methods After breaking thrombus through indwelling catheter,both bolus injection and micro-pump continuous infusion of urokinase was employed in eight hemodialysis patients with acute thrombosis in the arteriovenous fistula.The necessary nursing measures were carried out to assist the whole therapeutic procedure.Results All the patients could well cooperate with the procedure of indwelling catheter thrombolysis and urokinase infusion.The reopening rate of the obstructed fistula was 100%.Conclusion Indwelling catheter thrombolysis with urokinase infusion is a simple,effective and safe treatment for acute thrombosis in the arteriovenous fistula in hemodialysis patients.In order to obtain optimal results,necessary nursing measures must be carried out.

Objective To explore teaching effect of comprehensive teaching mode of PBL combined with CBL in ophthalmologic cataract clinical teaching.Methods 2008 grade clinical majors (n =80) in class 1 as experimental group were taught by comprehensive teaching mode of PBL combined with CBL while those (n =83) in class 2 as control group were taught by traditional LBL teaching mode.After the courses,the teaching effects of two methods were compared.SPSS 11.5 software was used for statistical analysis,x2 test for satisfaction survey and t-test for theoretical examination scores.The test level is α =0.05.Results There were significant differences between experimental group and control group in improving comprehensive quality and developing clinical thinking.Scores of understanding knowledge,case analysis and total scores of experimental group were higher than those of control group (all P ＜ 0.05).Conclusions Comprehensive teaching mode may improve the teaching effect of cataract clinical teaching,but it need to be explored and improved continually in practice.

Objective To explore the relationship among psychological capital,job burnout and job engagement of knowledge workers.Methods According to convenience sampling principle,727 information enterprise knowledge workers in Beijing were tested by Psychological Capital Scale,Maslach Burnout Inventory-General Survey (MBI-GS),Utrecht Work Engagement Scale(UWES),and the impact of psychological capital on job burnout and job engagement with correlation analysis and multivariate stepwise regression analysis were explored.Results The level of each dimension of the knowledge workers psychological capital (self-efficacy (4.72 ± 0.72),hope (4.62 ± 0.77),hardness (4.68 ± 0.72),optimism (4.36 ± 0.55)) were above average.The psychological capital total score and all dimensions were negatively correlated with job burnout,and positively correlated with job engagement.Stepwise multiple regression analysis showed that,after controlling three demographic statistics variables of gender,age,marital status,psychological capital could predict job burnout negatively,and predict job engagement positively; self-efficacy,hardness and optimism could significantly predict the three dimeusions of job burnout,hope could predict reduced personal accomplishment negatively;and self-efficacy could positively predict vigor,dedication and absorption,hardness could positively predict dedication and vigor.Conclusion Psychological capital can reduce the level of job burnout of knowledge workers,and improve their level of job engagement.

Objective To compare the curative effect of transforaminal lumbar interbody fusion by Wihse approach and posterior median approach in treatment of lumbar spinal canal stenosis.Methods Ninety-six patients with lumbar spinal canal stenosis were treated with transforaminal lumbar interbody fusion by Wihse approach (42 cases,Wihse group) and posterior median approach (54 cases,control group).The operation time,exposure time,exposure bleeding volume,length of incision,intraoperative bleeding volume,visual analog score (VAS) of nick at the third day after surgery,and VAS of lumbar and leg,Japanese orthopedic association (JOA) score and Roland-Morris disability questionnaire (RDQ) score at 1 year after surgery were compared between the 2 groups.Results The length of incision,exposure time,operation time,exposure bleeding volume,intraoperative bleeding volume,VAS of nick at the third day after surgery and VAS of lumbar at 1 year after surgery in Wiltse group were (5.0 ± 1.2) cm,(20.0 ± 7.6) min,(150.0 ± 8.4) min,(10.6 ±5.4) ml,(125.5 ± 10.6) ml,(4.5 ±0.6) scores and (1.0 ±0.5) scores,and in control group were (8.0 ± 1.6) cm,(35.2 ±6.8) min,(162.0 ±5.6) min,(84.5 ±7.8) ml,(186.4 ± 15.4) ml,(6.8 ± 0.5) scores and (2.5 ± 0.8) scores],there were statistical differences between the 2 groups (P ＜ 0.01).But there were no statistical differences in the VAS of leg,JOA score and RDQ score at 1 year after surgery between the 2 groups (P ＞ 0.05).Conclusion Two kinds of approach transforaminal lumbar interbody fusions all have good therapeutic effect on lumbar spinal canal stenosis,but the Wiltse approach has advantages of small incision,less intraoperative dissection,less bleeding and low incidence of postoperative lumbodynia.

Objective To treat hydrosalpinx by using interventional embolization of fallopian tube or laparoscopic salpingectomy before the performance of auxiliary reproductive technology,i.e.in vitro fertilization and embryo transplant (IVF-ET),and to compare the clinical effect,technical advantages and disadvamages between the two methods.Methods A total of 170 patients with tubal infertility who had received IVF-ET were selected,the clinical data were retrospectively analyzed.The patients were divided into three groups:(1) interventional embolization group (n=65),using interventional embolization for hydrosalpinx;(2) laparoscopic salpingectomy group (n=55),adopting laparoscopic salpingectomy for hydrosalpinx;and (3) control group (n=50):for these patients bilateral proximal fallopian tube obstruction was performed,and IVF-ET was directly carried out if the patient had no hydrosalpinx.Results No statistically significant differences in the used dosage of gonadotropin (Gn),E2 level on HCG-injection day,the number of follicles on HCG-injection day,the number of retrieved oocytes,the fertilization rate,cleavage rate,clinical pregnancy rate,abortion rate,and ectopic pregnancy rate existed between each other among the three groups (P＞0.05).The technical success rate in both interventional embolization group and laparoscopic salpingectomy group was 100％.No severe complications occurred.The interventional embolization procedure had some advantages,it could be completed at clinic room,the operation time was short,no anesthesia was needed,the medical cost was low,etc.Conclusion Interventional embolization of fallopian tube and laparoscopic resection are equally effective in treating hydrosalpinx before IVF-ET is conducted.Both methods can improve pregnancy outcome,but interventional embolization method is more simple,safe,economical and effective,which deserves to be the preferred method of treatment.

Objective To observe the effect of advanced oxidation protein products (AOPPs) on articular and synovial in a rabbit model of osteoarthritis (OA).Methods 48 male New Zealand rabbits were randomly divided into 3 groups:AOPPs group,PBS group and sham-operated group.OA model were created in AOPPs group and PBS group by anterior cruciate ligament transection and medial meniscus resection (ACLT+MMx).then intra-articular injection of 1 ml AOPPs or PBS were performed once every other day in AOPPs group and PBS group,respectively.In sham-operated group,the anterior cruciate ligament was just exposed without transection,and then the incision was sutured.All rabbits were saerificed after 4 and 8 weeks of intervention,respectively.Results The India ink seore of 4 and 8 weeks were 4.19±0.60,5.75±0.60 in AOPPs group,and 1.06±0.18,1.38±0.60 in sham-operated group,2.50±0.46、3.06±0.62 in PBS group,respectively.In addition,the differences were statistically significant among the three groups.The Mankin score of 4 and 8 weeks were 8.19±0.70,11.94±0.90 in AOPPs group,and 0.75±0.53,1.06± 0.73 in sham-operated group,4.25± 1.46、4.50±0.89 in PBS group,respectively.The differences were statistically significant among the three groups.Meanwhile,the protein expression level of matrix metalloproteinases (MMP)-3 on synovial at 4 and 8 weeks in AOPPs group were 1.006±0.080,1.098±0.088;0.065±0.006,0.053±0.011 in sham-operated group;and 0.552±0.024,0.839±0.084 in PBS group,respectively.The proteiu expression level of MMP-13 on synovial at 4 and 8 weeks in AOPPs group were 0.966±0.080,1.621 ±0.041;0.101±0.022,0.367±0.033 in sham-operated group;and 0.564±0.030,1.322±0.085 in PBS group,respectively.The differences were statistically significant among the three groups at two times.Conclusion AOPPs participate in the occurrence and development of artieular cartilage by upregulating the protein expression of MMP-3 and MMP-13 on synovial.
