OBJECTIVETo evaluate the clinical effect of arthroscopic excision of the os subfibulare in anterior-lateral ankle pain.

METHODSFrom December 2005 to Augest 2014, 16 patients suffering from pain associated with an os subfibulare in the anterior-lateral side of their ankles were reviewed. Among the patients,11 patients were male and 5 were female, with a mean age of (33.5 ± 15.6) years old. The mean maximum diameter of os subfibulare was (0.70 ± 0.26) cm. All the patients underwent excision of the osseous fragments, and had anatomic reconstruction of the anterior talofibular ligament if the anterior-lateral ankle was instable. The average follow-up period was (18.0 ± 4.5) months. To analyze the surgical outcome, American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot pain and function scales,visual analogue scale (VAS) and Tegner activity scale were assessed preoperatively and postoperatively.

RESULTSAOFAS scales were preoperative 60.15 ± 14.52 and postoperative 92.35 ± 5.73. There was a significant difference between them (t = -8.251, P = 0.000). The mean VAS score were preoperative 7.35 ± 0.46 and postoperative 2.45 ± 0.98. Statistical significance was also notable (t = 18.105, P = 0.000). Tegner score was significantly increased from preoperative 2.87 ± 1.12 to postoperative 5.78 ± 1.06 (t= -7.548, P = 0.000).

CONCLUSIONIrrespective of the size of os subfibulare, in patients with pain or instability associated with the os subfibulare, arthroscopic excision combined with reconstruction of ther anterior talofibular ligament or not was effective in restoring ankle function and eliminating pain.

Objective To learn the smoke-free environment and smoking status at or below county-level governments of Zhejiang Province, and to promote a smoke-free government.Methods By multi-stage random sampling method, 4 cities were selected in Zhejiang Province, then 4 counties were selected in 4 cities, finally12 governments were selected in 4 counties.With the methods of field observation,interview and questionnaire survey,smoke-free environment and smoking behavior , tobacco related knowledge of civil servants were investigated.Results A total of 12 governments and 405 civil servants were investigated.The smoke-free environment of 12 governments were relatively well.The total smoking rate of civil servants was 17.78%, and the highest was 26.67% in Jiande City, and the lowest were 9.00% in Zhuji City.For the civil servants ,male(26.62%), aged 50-(40.74%),divorced or widowed(40.00%),graduation of technical secondary school (33.33%),cadre of section rank(57.14%),above 20 years' work(28.81%),smoking anywhere at home(50.00%), smoking in certain areas at work(22.95%)were significantly higher.The rate of cognition on the hazards of smoking was lower among the smokers than that of non-smokers (P<0.05).The rate of agreement on MPOWER tobacco control strategies and smoking bans in public places were lower among the smokers than that of non-smokers (P<0.05).Non-conditional logistic regression analysis showed that age of 30-39(OR=9.87,95%CI:1.45-67.29),50-(OR=9.87,95%CI:1.45-67.29), smoking anywhere at home(OR=12.28,95%CI:2.95-51.18),and smoking in certain areas at home(OR=6.57,95%CI:3.07-14.08) may be the risk factors about smoking behavior.Conclusion The situation of smoking control at or below county-level governments in Zhejiang Province was good, and smoking rates has declined.But tobacco related knowledge and behavior of civil servants were relatively insufficient.Aiming at the problems found in the investigation, it is necessary to strengthen education on smoking control among civil servants, and to promote a smoke-free government.

BACKGROUNDSensitization in transplant candidates increases risk of irreversible immunologic injury of graft in the early period postoperatively. Elimination of anti-human leukocyte antigen (HLA) antibodies using protein A immunoadsorption (IA) might benefit these patients.

METHODSProtein A IA was used in 21 patients with high panel reactive antibody (PRA). The patients had IA 1 - 6 times (median 5 times) with the interval period was 2 - 5 days (median 2.5 days).

RESULTSTotal 67 IA procedures were carried out smoothly in all patients. IA treatment reduced PRA I (pre (31.4 ± 3.8)% vs. post (24.4 ± 3.4)%, P < 0.01) and II (pre (37.1 ± 4.3)% vs. post (34.1 ± 3.9)%, P < 0.01). However, PRA did not change in some patients after the treatment. The serum immunoglobulin (IgG, IgM and IgA) and complement C3, C4 level were decreased significantly. Hemoglobin and albumin levels were slightly decreased associated with IA procedures. Flu-like symptoms were observed in a few of cases during the procedure but generally mild and transient.

CONCLUSIONProtein A IA is capable to efficiently remove serum immunoglobulin and complement, reduce HLA class I and class II PRA in high sensitized transplant candidates, which is likely to benefit the kidney transplantation in these patients.

OBJECTIVETo understand allergic diseases related factors in Changzheng Town, Putuo District infants and young children.

METHODPregnant women registered in Putuo District, Changzheng Town Community Health Service Center Child Health Clinic within the period from January to December, 2008 were enrolled into this survey, a questionnaire survey. The infants were followed up from birth to 2 years of age. The mother and child survey was conducted for 746 pairs, and 684 pairs had complete data. SAS V9.1 statistical software was used for data processing and statistical analysis.

RESULTThe survey showed that prevalence of eczema, allergic rash, and wheezing was 27.9%, 18.9%, and 3.9%, respectively. Multivariate logistic regression analysis showed that allergy in either parent and addition of foods other than milk in infants before 4 months of age were risk factors for eczema; allergy in either parent was also risk factors for allergic rash. Exclusive breastfeeding from birth to 6 months of age was a protective factor for wheezing in infants. Other factors such as parental history of asthma, vitamin supplements to the mothers during pregnancy, mothers' special diet habits, calcium level of infants, etc. had no significant correlation with allergic disorders in infants.

CONCLUSIONThe risk factors for allergic disorders in infants included allergy in either parent and dietary factors of the infants themselves (prematurely adding other foods). Breastfeeding (for 0 - 6 months of age) was a protective factor for infants' wheezing.

Objective To observe the effects of Qijingmingmu decoction granule on the expression of mitogen-activated protein linase (MAPK) signal pathway in fibroblasts of conjunctivochalasis (CCH) under the stimulation of tumor necrosis factor (TNF-α) and to explore the pathogenesis and effective treatment method of CCH.Methods CCH conjunctival fibroblasts were cultured in vitro and divided into CCH group,CCH + TNF-α group and CCH + TNF-α + Qijingmingmu decoction group.CCK-8 assay was used to determine the effective concentration of Qijingmingmu decoction granule,and 10-2 mg · L-1 TNF-α was added in the cultured fibroblasts of the latter two groups,followed by interference with Qijingmingmu decoction granule for 48h.The expression of MAPK signal pathway related protein and mRNA were detected by ELISA,Western Blot and RT-PCR.Then the results were statistically analyzed.Results CCK-8 assay showed the effective concentration of Qijingmingmu decoction granule was 1.61g · L-1.And there were significant differences in the total A values (A450) of extracellular regulated protein kinase (ERK),c-jun N-terminal kinase (JNK),p38 mitogen activated protein kinase (p38 MAPK) and their phosphorylation levels among the three groups (all P ＜ 0.05).Moreover,TNF-α could significantly up-regulate the expression of ERK1/2,JNK1/2,p-JNK1/2,p38 MAPK and p-p38 MAPK in CCH fibroblasts (all P ＜0.05),while Qijingmingmu decoction down-regulated their expressions in CCK fibroblasts after TNF-α stimulation (all P ＜ 0.05).Furthermore,the total differences in p-ERK1/2,p38 MAPK and p-p38 MAPK protein were significant in the three groups (all P＜0.05);and TNF-α could significantly up-regulate the expression of p-ERK1/2,p-JNK1/2,p38 MAPK and p-p38 MAPK protein in CCH fibroblasts (all P ＜0.05),while Qijingmingmu decoction down-regulated p-ERK1/2 and p38 MAPK expressions in CCK fibroblasts after TNF-α stimulation (both P ＜ 0.05).In addition,the total differences in ERK1/2 and p38 MAPK mRNA were significant in the three groups (both P ＜ 0.05);and TNF-α could significantly up-regulate the expression of ERK1/2 and p38 MAPK mRNA in CCH fibroblasts (both P ＜ 0.05),while Qijingmingmu decoction down-regulated p38 MAPK mRNA expressions in CCK fibroblasts after TNF-α stimulation (P ＜ 0.05).Conclusion The inflammatory factor TNF-α can up-regulate the expressions of MAPK signal pathway related protein and mRNA in CCH fibroblasts,resulting in the occurrence and development of CCH,and meanwhile Qijingmingmu decoction granule can downregulate the expression of MAPK signal pathway to play the therapeutic role in CCH to some extent.

Objective To investigate the current situation of empathy and self-efficacy, and relation with perform-ance of objective structured clinical examination in residents of standardized training. Methods Questionnaire sur-veys with Jefferson scale of empathy health professionals and general self-efficacy scale were conducted among resi-dents of grade 2015 and grade 2016 from department of internal medicine of Peking Union Medical College Hospital (PUMCH). Results Totally 101 questionnaires were delivered,and 99 were collected back. The average empathy score was 111.3±1.2,with that of grade 2015 slightly higher than that of grade 2016. The empathy score from resi-dents of different degree and different sources showed no significant difference. The average self-efficacy score was 22.77±0.50. The score of residents of grade 2015 was significantly higher than that of grade 2016. The score was higher in residents with higher degree. The score of residents from PUMCH was higher than the other subgroups. The score of empathy showed no significant correlation with OSCE scores, while the score of self-efficacy of resi-dents of grade 2015 significantly positively correlated with scores of medical recording (R=0.35,P<0.05),case analyzing (R=0.31,P<0.05) and average score(R=0.33,P<0.05) of OSCE. Conclusions The empathy and self-efficacy of residents remained to be improved, and could be improved through clinical training. Psychological evaluation could be inducted into standardized resident training system,and provide helpful supplementary to OSCE with more comprehensive evaluation of residents.

OBJECTIVETo evaluate the efficacy and safety of entecavir maleate (ETV) versus ETV in Chinese patients with hepatitis B e antigen(HBeAg)-positive chronic hepatitis B(CHB).

METHODSThe patient population of this previously published randomized, double-blind, double-dummy, controlled, multicenter study was expanded by patients in the 0.5 mg/day ETV maleate group (total n = 110) and patients in the 0.5 mg/day ETV group (total n = 108). At treatment weeks 12, 24 and 48, hepatitis B virus (HBV) DNA levels were measured by the Roche Cobas Ampliprep/Cobas Taqman PCR assay. Adverse events (AE) were recorded.

RESULTSAs in the original analysis, the two treatment groups showed similar characteristics at baseline. In addition, the results for the all therapeutic effects showed identical trends to the results obtained in the original analysis, including the statistically similar effects of ETV and ETV maleate treatment-induced decreases in mean HBV DNA level at weeks 12, 24, and 48 (ETV: by 4.28, 5.00, and 5.53 log10 IU/ml vs. ETV maleate: by 4.46, 4.99, and 5.51 log10 IU/ml, respectively; all vs. baseline P more than 0.05), achievement of undetectable levels of serum HBV DNA ( less than 20 IU/ml) at week 48 (ETV: 38.18% vs. ETV maleate: 35.19%; P more than 0.05), HBeAg loss rates at week 48 (ETV: 10.91% vs. ETV maleate: 12.96%; P more than 0.05), HBeAg seroconversion rates at week 48 (ETV: 7.77% vs. ETV maleate: 10.38%; P more than 0.05), normalization of alanine aminotransferase at week 48 (ETV: 75.47% vs. ETV maleate: 82.86%; P more than 0.05), and overall incidence of AE (ETV: 18.02% vs. ETV maleate: 17.43%; P more than 0.05).

CONCLUSIONPerforming analysis of the therapeutic efficacies of entecavir maleate versus entecavir with a larger study population confirmed our original findings of similar efficacy and safety profiles for these two drugs in patients with HBeAg-positive CHB.
