Objective To explore the factors related with osteoporosis in middle-aged men who accepted high education. Methods 306 men were investigated about their bone density, also their behaviors, diet, exercise and so on. Results The incidence of osteoporosis increased with the aging. The Logistic regression showed that smoking (OR=4.61) and alcohol intake (OR=1.11) were the risk factors for osteoporosis,while the milk intake (OR=0.19) and exercise (OR=0.13) were the protective factors. Conclusion The low bone mass and osteoporosis of middle-aged men accepted high education are associated with the age, smoking, alcohol or milk intake and exercise.

ObjectiveTo observe the effect of acupuncture plus language function training on the recovery of language function in patients with post-stroke aphasia.MethodNinety patients were divided into an acupuncture-rehabilitation group (intervened by acupuncture plus language function training) of 30 cases, an acupuncture group (intervened by acupuncture alone) of 30 cases, and a control group (intervened by language function training alone) of 30 cases. The Western Aphasia Battery (WAB) was adopted to evaluate the language function, and also taken as criteria for diagnosis and therapeutic efficacy. The aphasia quotient (AQ), and the 4 basic language functions including spontaneous speech, auditory comprehension, repetition and nomination were observed. ResultAfter intervention, AQ, and scores of spontaneous speech, auditory comprehension, repetition and nomination increased significantly in the three groups (P<0.05,P<0.01). there were significant differences in comparing the scores of spontaneous speech, repetition and nomination between the acupuncture-rehabilitation group and the control group (P<0.05). There were no significant differences in comparing the indexes between the acupuncture group and control group (P>0.05).ConclusionAcupuncture plus language function training can produce a positive effect on patients with post-stroke aphasia, showing therapeutic advantage in improvingspontaneous speech, repetition, and nomination.

OBJECTIVETo explore the clinical value of the neonatal hearing combined with deafness gene screening.METHODSFrom February 2014 to August 2015, 1933 newborns were included in the study. We analyzed the effects of combined screening of hearing and deafness gene.RESULTSAmong all the 1933 neonates, 71.34% (1379/1933) passed and 28.66% (554/1933) failed the initial hearing screening.The hearing impairment rate was 4.14‰ (8/1933). Genetic screening mutation rate was counted. GJB2 mutation rate was 28.97‰ (56/1933). SLC26A4 mutation rate was 13.97‰ (27/1933). GJB3 mutation rate was 6.21‰ (12/1933). Mitochondrial 12 S rRNA gene mutation rate was 1.03‰ (2/1933). 1 case of 235 delc homozygous mutation did not pass the initial hearing screening and lost to follow-up rescreening. 2 cases of 12 S rRNA 1555A>G homogeneous mutations passed early hearing screening. 8 cases of auditory handicaps were all normal.CONCLUSIONDeafness gene screening can make up for the deficiencies of the universal newborn hearing screening. Joint use of both of them should complement each other and play the biggest role.

ObjectiveTo observe the clinical efficacy of moxibustion plus acupoint autohemotherapy in treating allergic rhinitis due to lung-spleen qi deficiency.MethodTotally 120 eligible subjects were divided by using the random number table into a comprehensive group, a moxibustion group and a Western medication group. The comprehensive group was intervened by moxibustion plus acupoint autohemotherapy, the moxibustion group was by moxibustion,and the Western medication group was by Loratadine tablets. The acupoint autohemotherapy was give twice a week and the rest treatments were given once a day, 7 das a course, for 4 courses in total. A follow-up study was conducted 3 months later. The clinic efficacy was evaluated before and after intervention, as well as in the follow-up study.ResultThe three groups all achieved significant short-term efficacies after intervention, and the comprehensive group was equivalent to the moxibustion group, bothsuperior to the Western medication group(P<0.05). According to the follow-up study, the long-term efficacies of the comprehensive group and moxibustion group were both significantly higher than that of the Western medication group (P<0.01,P<0.05), and the moxibustion group was superior to the comprehensive group in comparing the long-term efficacy (P<0.01).ConclusionMoxibustion plus acupoint autohemotherapy and dry moxibustion both can produce significant short-term and long-term therapeutic efficacies in treating allergic rhinitis due to lung-spleen qi deficiency. The long-term efficacy of moxibustion is higher than that of moxibustion plus acupoint autohemotherapy in treating allergic rhinitis due to lung-spleen qi deficiency. Acupoint autohemotherapy requires strict aseptic operation, which restricts its application in family healthcare. Long-term use of moxibustion can activate yang qi, and thus plays a role in preventing diseases.

Objective To analyze and evaluate the characteristics of enzyme kinetics of CTX-M-14 type extended-spectrum β-lactamase(ESBL) with Pro167 residue substitution. Methods By molecular cloning and PCR techniques, CTX-M-14 gene was directionally cloned into plasmid pET28a( + ) from a clinical E. coli isolate and formed an expression vector to transform competent E. coli BL21 (DE3 ). Prol67 residue substitutions of P167G, P167Q, P167S and P167T were introduced to CTX-M-14 by site-directed muta-genesis based on overlap extension PCR with the former recombinant plasmid as PCR template, respectively.The wild-type CTX-M-14, recombinant CTX-M-14 protein and its variants were expressed and purified, then their steady-state kinetic parameters (Kcat, Km and Kcat/Km ) against β-lactam antibiotics were determined.Results The kinetic parameters of wild-type and recombinant CTX-M-14 had no statistically significant differences (P>0.1). The 1/Km, Kcat and Kcat/Km values of P167S variant against ceftazidime were 16-fold, 2.87-fold and 43.6-fold higher than those of recombinant CTX-M-14, respectively, and the Kcat/Km value of P167S variant against penicillin, ampicillin, cefazolin, cefuroxime, ceftriaxone, cefotaxime decreased( < 0.05). Compared with the kinetic parameters of recombinant CTX-M-14, the kinetic parameters of P167T variant against ceftazidime had no significant change, but the Kcat values of P167Q and P167G variants decreased dramatically(P<0.01). Conclusion There was no difference between the enzyme activities of wild-type and recombinant CTX-M-14. P167S variant could not only promote the enzyme affinity of CTX-M-14 to ceftazidime but also improve the conversion rate of enzyme-substrate complex in the ceftazidime hydrolysis. The comparison of the kinetic parameters of CTX-M-14 and its variants with Pro167 residue substitution showed that the increased activity of CTX-M ESBL variants against ceftazidime could not be simply explained with the enlarged cavity in active site that may be caused by the replacement of Pro167 residue by smaller amino acids.

Objective To compare the short-term efficacy of pylorus-preserving pancreaticoduodenectomy (PPPD) and standard pancreaticoduodenectomy (SPD) for the treatment of periampullary carcinoma.Methods The clinical data of 85 patients with periampullary carcinoma who were admitted to the Zhongshan Hospital of Fudan University from October 2010 to October 2012 were retrospectively analyzed.Forty-four patients who underwent PPPD were divided into the PPPD group and 41 patients who underwent SPD were divided into the SPD group.The pancreatic fistula(Grade B and above), biliary fistula, blood loss, intra-abdominal infection, delayed gastric emptying (DGE) and prognosis were analyzed.Patients were followed up by telephone interview and outpatient examination once every 3 months within postoperative 1 year and once every 6 months within postoperative 2-3 years till October 2014.Count data were analyzed using the chi-square test, measurement data with normal distribution were presented as M(Qn) and comparison was analyzed using the Mann-Whitney U test.The survival curve was drawn by the Kaplan-Meier method, and survival rate was analyzed using the Log rank test.Results The operation time was 195 minutes (180 minutes, 240 minutes) in the PPPD group and 210 minutes (180 minutes,300 minutes) in the SPD group, with a significant difference (Z =-2.090, P ＜ 0.05).The volume of intraoperative blood loss, intraoperative blood transfusion and duration of postoperative hospital stay were 200 mL(113 mL,288 mL), 0 mL(0 mL, 0 mL) and 17 days(12 days, 24 days) in the PPPD group, and 200 mL(150 mL, 325 mL),0 mL(0 mL, 400 mL) and 16 days(12 days, 30 days) in the SPD group respectively, with no significant differences between the 2 groups (Z =-1.185,-1.780,-0.533, P ＞0.05).There was no perioperative death and incidence of overall complication was 42.4％ (36/85) with pancreatic fistula, intra-abdominal infection and DGE as the top 3 common postoperative complications.The incidence of DGE was 20.5％ (9/44) in the PPPD group,which was significantly different from 4.9％ (2/41) in the SPD group (x2=4.571, P ＜ 0.05).The incidence of pancreatic fistula, biliary fistula, intra-abdominal infection, postoperative bleeding and 2 or more complications were 20.5 ％ (9/44), 2.3 ％ (1/44), 15.9％ (7/44), 4.5 ％ (2/44), 25.0％ (11/44) in the PPPD group, and 14.6％ (6/41), 4.9％ (2/41), 19.5％ (8/41), 7.3％ (3/41), 14.6％ (6/41) in the SPD group, respectively, showing no significant difference between the 2 groups (x2=0.495, 0.423, 0.295, 0.190, 1.425, P ＞ 0.05).Eighty-five patients were followed up for 6-47 months with a median time of 31 months, and postoperative overall 1-and 3-year survival rates were 95.3％ and 75.5％, respectively.The 1-and 3-year survival rates were 97.7％ and 78.9％ in the PPPD group, and 92.7％ and 71.7％ in the SPD group, respectively, with no significant difference in 3-year survival rate (x2=0.690, P ＞0.05).The 3-year overall survival rate was 80.5％ in patients without lymph node involvement (LNI) compared with 54.9％ in patients with LNI, showing a significant difference (x2=4.290, P ＜ 0.05).Conclusions Both PPPD and SPD have good short-term efficacy for periampullary carcinoma.There is no significant difference between PPPD and SPD concerning short-term survival rate of periampullary carcinoma.PPPD has shorter operation time, but has a higher postoperative DGE incidence.LNI is a significant prognostic factor for short-term survival of periampullary carcinoma.PPPD is not recommended while the lymph nodes are involved.

BackgroundIdiopathic epiretinal membranes(ERMs) is a common eye disease condition that leads to progressive decline of visual acuity. Studying the risk factors relating to this disease will shed light on its pathogenesis and allow opthalmologists to screen the affected individuals among the high-risk population and prepare for prevention and management strategies. ObjectiveThis survey was to investigate the risk factors of idiopathic ERMs in the population undergoing routine health check-ups. MethodsThe clinical data of idiopathic ERMs was obtained from the population of routine health check-ups in Peking Union Medical College Hospital from November 2009 to October 2010. The examination outcomes were compared between the individuals with and without idiopathic ERMs. The demographic and clinical factors associated with idiopathic ERMs were analyzed and assessed using univariate and multivariate logistic regression analyses. Result A total of 27 400 people were included in the survey and idiopathic ERMs were diagnosed in 76 cases. No obvious eye complaint was obtained from the idiopathic ERMs. The number of people affected with idiopathic ERMs was 12 ( 12/11 659 ) in the below 40 years group, 21 (21/4595) in the 51-60 years group and 32 (32/2544) in the over 60 years group. Hypertension, diabetes, diedyslipidemia, renal function insufficiency ,and cataract were found in 42％ ,5％ ,66％ ,6％ and 8％ of the patients, respectively. The univariate logistic regression analyses revealed that significant correlations were found between age,hypertension,hyperlipidemia and history of cataract( P＜0. 01 ). Multivariate regression models showed that the risk of idiopathic ERMs increased in age of 51-60( OR=2. 5,95％ CI:1. 2-5.4,P=0.02) and over 60 years( OR =7.3,95％ CI:3.4-15.6 ,P＜0.01 ) and patients suffering from hyperlipidemia ( OR--2. 1,95％ CI:1. 3-3.5, P＜0. 01 ). ConclusionsOver the age of 50 years and hyperlipidemia are primary risk factors of idiopathic ERM.
