Objective To investigate the factors influencing compliance behavior and treatment effect of glaucoma patients, and explore evidence-based nursing on compliance behavior and treatment effect of these patients. Methods 110 subjects with glaucoma were enrolled from Tangshan Gongren hospital. The subjects were randomly divided into the experimental group and the control group with 55 patients in each. The experimental group accepted evidence- based nursing while the control group accepted traditional nursing. The percentage of compliance behavior and treatment effect were statistically analyzed. Results The percentage of compliance behavior and treatment effect of the experimental group was better than the control group. Conclusions Evidence-based nursing played an important role on compliance behavior and controlling the intraocular pressure in patients with glaucoma.

Objective　To prepare monoclonal antibody (McAb) pool against Bacteroides fragilis and Clostridium perfringens and evaluated its effect in rapid diagnosis in surgical infection. Methods　After the preparation of monoclonal antibodies against B. fragilis and C. perfringens, 191 specimens collected from infectious patients was detected with indirect immunofluorescent antibody (IFA) and enzyme labeled antibody (ELA). The results were compared with routine cultural method (CM). Results　Among the 191 specimens, 53 (27.7%), 55 (28.8%) and 25 (13.1%)strains of B. fragilis were detected with IFA, ELA and CM respectively, and for C.perfringens, 12(6.3%), 11(5.8%), and 6(3.1%) strains were found. The detectable rate of anaerobic bacteria by IFA and ELA was higher than by CM, but no difference was found between these 2. Conclusion　The self-made McAb pool against B.fagilis and C.perfringens might be a rapid, specific, sensitive and simple McAb pool for detecting B.fragilis in surgical infection and C.perfringens in wartime.

Objective To study clinical curative effect and complications of modified laparoscopic sacral colpopexy and evaluate the efficacy and safety of this procedure in treatment of pelvic organ prolapse (POP).Methods From Jan.2008 to Sept.2012,66 patients who had undergone modified laparoscopic sacral colpopexy for POP in the first affiliated hospital of Guangzhou medical university were studied retrospectively.Primary outcomes were assessed with POP quantitation (POP-Q) system that was measured before or after operation respectively to evaluate the objective cure rate and recurrence rate.Secondary outcomes were measured by the pelvic floor distress inventory short form (PFDI-20) to evaluate the subjective cure rate,as well as to evaluate the improvement of postoperative lower urinary tract symptoms.Results Sixty-three patients were followed up for 6 to 57 months,and the median follow-up time was 16 months,the overall objective cure rate was 95％ (60/63).Postoperative each indicator point was reset anatomically according to POP-Q,the overall objective cure rate was 90％ (57/63),and the total recurrence rate was 10％ (6/63).The median postoperative vaginal length was slightly shortened than preoperative length[7.5 cm versus 8.0 cm,P ＜ 0.01]; the median score of postoperative PFDI-20 was obviously improved compared to the preoperative (21 versus 75 scores,P ＜ 0.05) ; there was no statistically significant difference in POP-Q staging and questionnaire score at more than 3 years,＞ 2-≤ 3 years,＞1-≤2 years,＜0.5-1 year after operation(P ＞0.05).Among 23 patients with stress urinary incontinence (SUI) and 5 patients with mixed urinary incontinence (MUI),15 cases underwent transvaginal tension free vaginal tape-obturator (TVT-O) procedure simultaneously,13 cases did not.The cure rate of SUI was 14/15 and 10/13,respectively.Conclusions Modified laparoscopic sacral colpopexy can not only reach the anatomical replacement stage but significantly improve the postoperative quality of life with high subjective and objective cure rate and few complications.The long-term curative effect is stable.

ObjectiveTo study the distribution,location and hemodynamics of perforating branches of the ulnar artery with color Doppler flow imaging (CDFI).MethodsPerforating branches of ulnar arteries were examined in 80 healthy volunteers in both forearms using CDFI.Following parameters were detected:number,diameter,jumping-off point,course,location and peak blood velocity.All the parameters data were analyzed statistically.ResultsThree hundred and forty-five perforating branches were detected in total 160ulnar arteries.These branches were classified into three types:type Ⅰ,myocutaneous perforator (10.3 ％);type Ⅱ,septocutaneous perforator(87 ％ ) ; type Ⅲ,direct cutaneous perforator (2.7 ％ ).The most dominant branches were located in the mesial of the upper third,middle third and lower third of the forearm.There was no significant difference among all age groups and no difference in peak blood velocity between left side and right side( P ＞0.05).The peak blood velocity was higher in male than that in female.( P ＜0.05).In relaxing period,the blood flow rate was almost disappeared and the frequency spectrum showed the characteristics of single direction,lower blood velocity and higher blood resistance.ConclusionsCDFI with high resolution showed better results of distribution and location of perforating branches of the ulnar artery and a better quality evaluation of the these branches.CDFI was helpful to design the skin flap containing cutaneous perforators of ulnar artery.

Objective To analyze the genotypes of clinical varicella-zoster virus(VZV) isolates in Tibet.Methods The samples of vesicular fluid from patients with chickenpox or zoster were collected to isolate VZV in human embryonic fibroblast cells.Furtherly,the isolated VZV were identified by indirect immunofluorescence assay and the positive ones were continuely cultured in vitro to get their genome DNAs.Then,PCR and nucleotide sequencing were performed on the part of open reading frames 1,21,50,54.To confirm the genotypes of isolated virus strains,the gene sequences obtained from PCR products were compared with that in GenBank of VZV Dumas strains,and their restriction enzyme sites were analyzed via Primer 5.0.Results Ten clinical isolates of VZV were obtained from sixteen specimens,the positive isolation rate was 62.5％.Gene analysis showed that among all the ten clinical isolates of VZV in Tibet,three strains are genotype A1,four are genotype A2 and the other three are genotype J1.Conclusion The VZV genotype distribution in Tibet was tightly related to their special geographic locations.

Objective To construct a colon cancer chemotherapy-resistant cell line COLO,and study its characteristics and its relationship with tumor stem cells.Methods We constructed two 5-fluorouraci (5-FU)-resistant colon cancer cell line COLO/5-FU-1 and COLO/5-FU-2, which were resistant to 0.1 0 μmol/ml and 0.20 μmol/ml 5-FU respectively through gradiently increased drug concentration.The cha-racteristics of 5-FU-resistant cell lines were compared with parental colon cancer cell line COLO related to proli-feration,colony forming ability,migration and invasion,sphere forming ability,expression of stemness genes and cross drug-resistance.Results In the cell viability assay,4 days after regular training,the absorbancy of colon cancer 5-FU-resistant cell lines COLO/5-FU-2,COLO/5-FU-1 and parental colon cancer cell line COLO were 0.61 ±0.1 3,0.54 ±0.07 and 0.41 ±0.09 respectively,with significant difference (F =63.43,P =0.033).With the increased concentration of 5-FU,5-FU-resistant cell lines presented increasing clonality. The cloning efficiency of COLO/5-FU-2,COLO/5-FU-1 and parental colon cancer cell line COLO were (87.6 ±1 2.7)%,(65.3 ±9.7)% and (38.5 ±7.6)% respectively,with significant difference (F =33.64, P =0.01 7).In each high power field of vision,the cell numbers of migration through the basement membrane of COLO/5-FU-2,COLO/5-FU-1 and parental colon cancer cell line COLO were 482 ±39,434 ±45 and 373 ±38 respectively;and the cell numbers of invasion through the basement membrane were 1 74 ±42,1 1 2 ± 31 and 87 ±29 respectively,with significant differences (F =1 09.61 ,P =0.009;F =67.31 ,P =0.032). Compared with parental colon cancer cell line COLO,5-FU-resistant cell lines had higher expression of stem-ness genes (F =47.31 ,P =0.042).5-FU-resistant cell lines were cross-resistant to other chemotherapeutic drugs such as mitoxantrone.For example,after incubation for 96 hours,inhibition rate of mitoxantrone to parent colon cancer cell line COLO was higher significantly than COLO/5-FU-1 and COLO/5-FU-2 (0.749 ± 0.042,0.423 ±0.024,0.342 ±0.01 8),with significant difference (F =1 2.61 ,P =0.028).The micro-sphere forming rates of COLO/5-FU-2,COLO/5-FU-1 and parental colon cancer cell line COLO were (8.90 ± 0.97)%,(6.20 ±0.75)% and (3.90 ±0.32)% respectively,with significant difference (F =1 64.32,P =0.006).Conclusion Colon cancer drug-resistant cell line COLO possess tumor stem cell-like characteristics, which are enriched in cancer stem cells.

Objective To study the correlation between interleukin(IL)-21 and the recurrence of chronic hepatitis B(CHB)in hepatitis B e antigen(HBeAg)-positive patients after discontinuation of entecavir(ETV).Methods A total of 112 HBeAg-positive CHB patients treated with ETV were enrolled.Serum levels of IL-21 at week 0,12,24 and 52 after ETV discontinuation were detected.The Cox regression model was used to analyze the correlation between IL-21 and the recurrence after ETV discontinuation.The receiver operating characteristic(ROC)curve was applied to determine the predictive value of IL-21 for CHB recurrence after ETV discontinuation.The expression differences of IL-21 were compared between sustained viral response(SVR)group and viral relapse(VR)group.The t test and Chi-square test were used for statistical analysis.Results The serum levels of IL-21 in SVR group at week 0,12,24 and 52 after ETV withdrawal were(60.0 ± 10.8),(60.2 ± 14.7),(60.6 ± 19.5)and (61.2 ± 15.4)ng/L,respectively,which were all significantly higher than those in VR group(47.5 ± 10.7),(47.3 ± 12.9),(46.9 ± 12.2)and(46.4 ± 12.8)ng/L,respectively(t=6.153,4.926,4.382 and 5.515,respectively,all P< 0.01).The area under curve(AUC)was 0.811(95% CI:0.728 ~0.893,P<0.01)and the best cut-off value of serum IL-21 level was 49.8 ng/L.The recurrence rates of patients with serum IL-21 level ≥49.8 ng/L and <49.8 ng/L at time of ETV withdrawal was 25.4%(16/63)and 77.6%(38/49),respectively.The difference was statistically significant(χ2=30.027,P<0.01).The serum IL-21 level at the time of drug withdrawal(P= 0.005),serum hepatitis B surface antigen(HBsAg)level at the time of HBeAg seroconversion(P= 0.008)and age(P= 0.016)were factors associated with CHB recurrence after ETV withdrawal by multivariate Cox model analysis.The serum levels of ALT,HBV DNA,HBeAg and HBsAg in SVR group were significantly lower than those of VR group at week 12,24 and 52 after ETV withdrawal(t= -5.968,-7.691,-8.093; -3.047,-9.477,-28.900;-2.872,-10.424,-18.330;-4.633,-4.030 and -5.032,respectively;all P<0.01).Serum level of IL-21 was negatively correlated with HBsAg in SVR group after ETV withdrawal (r= -0.241,P<0.01),while positively correlated with HBsAg in VR group(r=0.286,P<0.01). Conclusions The serum IL-21 level at the time of drug withdrawal is associated with the recurrence after ETV discontinuation.IL-2l may play an important role as an immunomodulatory factor in maintaining virological responses in HBeAg-positive CHB patients after ETV withdrawal.

Hip fractures are among the most common fractures in the elderly, presenting to be a leading cause of disability and mortality. Surgical treatment is currently the main treatment method for hip fractures. The incidence of perioperative malnutrition is increased after hip fractures in the elderly due to the comorbidities, decreased basal metabolic rate, accelerated protein breakdown, weakened anabolism and surgical stress. However, malnutrition not only increases the incidence of postoperative complications, but also leads to increased mortality, indicating an important role of perioperative nursing management of nutrition for the elderly patients with hip fractures. At present, there still lacks scientific guidance and application standards on perioperative nursing management of nutrition for the elderly patients with hip fractures. Therefore, the Orthopedic Nursing Committee of Chinese Nursing Association and the Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Expert consensus on perioperative nursing management of nutrition for elderly patients with hip fractures ( version 2023) according to evidence-based medical evidences and their clinical experiences. Fourteen recommendations were made from aspects of nutrition screening, nutrition assessment, nutrition diagnosis, nutrition intervention and nutrition monitoring to provide guidance for perioperative nursing management of nutrition in elderly patients with hip fractures.

Objective: To explore the characteristics underlying Th1/Th2/Th17 expression level after entecavir (ETV) discontinuation of chronic hepatitis B (CHB) patients who were HBeAg-positive and define the role of Th1/Th2/Th17 in maintaining virological response after ETV discontinuation. Methods: We selected 112 HBeAg positive CHB patients who met the withdrawal criteria according to the guideline of prevention and treatment of chronic hepatitis B (2010 version), and we also separated them into virology sustained response (SVR) group and virological relapse (VR) group according to the recurrence in 52 weeks. We detected serum level of Th1/Th2/h17 related cytokines during 0, 12, 24 and 52 weeks follow-up to further analyze their dynamic changes and expression differences. Results: The results of the study reveals that serum levels of IFN-γ in the group of SVR were at a higher level compared with VR group during follow-up (all P<0.05). While, the serum level of IL-10 decreased in SVR group and was lower than the paired IL-10 level in VR group with significance during follow-up. In VR group, the serum level of IFN-γ decreased during the first 24 weeks after ETV withdrawal, and after then, the level rose. The serum levels of IFN-γ (Th1) in SVR patients were significantly higher than those in VR patients in the different follow-up time points after ETV discontinuation (all P<0.05). And the serum levels of IL-10 (Th2) in SVR patients were significantly lower than that in VR patients (all P<0.05). The comparison of serum levels of IL-17A (Th17) between the two groups had no significant difference (all P>0.005). Conclusions The serum level of IFN-γ in SVR group maintained a high level is conducive to maintaining virological response after ETV withdrawal and high level of IL-10 may be related to virologic relapse.
