Objective To evaluate the value of 99Tcm-MDP uptake by left femoral neck for diagnosing osteopomsis.Methods A total of 58 cases (23 males,35 females,mean age:(66.15±8.45) years) with spondyloarthmpathies from May to December of 2012 were selected.Serum concentrations of type Ⅰ collagen telopeptide (sCTX-1) and bone ALP (BALP) were determined.All patients underwent dual-energy X-ray absorptiometry (DXA) to detect bone mineral density (BMD).According to the T scores,patients were divided into 2 groups:normal group (NG) (T＞-1.0) and osteoporosis group (OG) (T≤-2.5).99TcmMDP bone scan was further performed.The average radioactive ratio of the left femoral neck to the medial soft tissue of left femur (T/N) was measured.Data differences between the 2 groups were compared by twosample t test and Pearson correlation analysis.Results According to BMD,13 patients (7 males,6 females) were included in NG and 28 patients (10 males,18 females) were included in OG.The mean ages of OG and NG were significantly different ((68.82± 10.41) years vs (62.46± 11.77) years; t =3.560,P＜0.05).The BMD of left femoral neck in OG was significantly lower than that in NG ((0.67±0.08) g/cm2 vs (0.91±0.10) g/cm2 ; t=9.917,P＜0.01).Although BALP level of OG was significantly higher than that of NG ((35.92±11.58) U/L vs (22.38±6.34) U/L; t=-3.397,P＜0.05),no significant difference was observed on sCTX-1 between the 2 groups (t=-0.463,P＞0.05).T/N ratio of OG (11.63±6.22) was higher than that of NG (9.74±4.44) (t =-3.027,P＜ 0.05).There were significant correlations between the T/N ratio of the left femoral neck and the sCTX-1 and BALP concentrations (r=0.376,0.483,both P＜0.01).No correlations between the T/N ratio of the left femoral neck and age,BMI and BMD were observed (r=-2.031,-0.017,0.134,all P＞0.05).Conclusion The uptake ratio of the left femoral neck in 99Tcm-MDP bone scan could evaluate the metabolism of bone,and it is useful for the early diagnosis of osteoporosis.

Objective:To investigate the prevalence and related risk factors of diabetic retinopathy (DR) among registered residents of type 2 diabetes mellitus in Jiading Industrial Zone Community Health Service Center,Shanghai.Methods:In this cross-sectional study,diabetic retinopathy was screened among registered residents with type 2 diabetes in Jiading Industrial Zone Community Health Service Center,Shanghai.The prevalence and risk factors of DR were evaluated by combining questionnaire and clinical examination.Results:Among 776 subjects who were chosen,695 people completed the study,and the overall response rate was 89.56％.26 cases were excluded because the refractive medium was opaque and the retina could not be seen clearly.DR was detected in 91 patients (13.60％).The mean duration of diabetes in patients with DR and without DR was (9.63±6.44) years and (7.02±5.32) years (OR=1.073,95％ CI 1.036-1.111,P＜0.001),the fasting blood glucose was (8.66±2.66) mmol/L and (7.52±2.15) mmol/L (OR=1.219,95％ CI 1.119-1.328,P＜0.001),glycated hemoglobin was (7.68±1.55)％ and (6.99±1.21)％ (OR=1.495,95％ CI 1.275-1.754,P＜0.001).There was also statistically significant difference in the use of insulin between DR patients and non-DR patients (OR=4.202,95 ％ CI 2.504-7.051,P＜0.001).Conclusions:The prevalence of DR among type 2 diabetes patients is 13.6％ in Jiading Industrial Zone,Shanghai.The longer the duration of diabetes is,the higher the fasting blood glucose is,the higher the glycosylated hemoglobin is,the greater the risk of DR will be.

To explore the anti-tumor proliferation activity of human interleukin-29 (hIL-29) variant and based on bioinformatics analyzed data of hIL-29, a mutant gene hIL-29(mut33,35) was amplified by site-directed mutagenesis and megaprimer PCR. The hIL-29(mut33,35) was inserted into an eukaryotic expression plasmid pPIC9K and successfully expressed in Pichia pastoris GS115. A recombinant variant protein (rhIL-29(mut33,35)) was purified from the ferment supernatant of the engineering GS115. To observe the antineoplastic activity of the variant rhIL-29(mut33,35), a CCK-8 reagent was used to detect the anti-proliferation effect. Results show that it has strong anti-proliferation effect when acted on liver cancer cell BEL7402, colon cancer cell HCT8 and gastric cancer cell SGC7901. The inhibition ratios of the three tumor cells were (30.99 ± 1.58)%, (22.47 ± 1.37)% and (32.05 ± 2.02)%, respectively. In high dose group, the anti-proliferation effect of the rhIL-29(mut33,35) was stronger than that of wild type rhIL-29 (P < 0.01). This indicates the variant rhIL-29(mut33,35) has potential development value for medicine.

Objective To assess the value of serum amyloid A (SAA) in patients with acute asthma attack. Methods Sixty-four asthmatic patients in acute phase and 20 healthy individuals were included. The asthmatic patients were divided into bacterial infection-induced group and non-bacterial infection-induced group. Lung function test and chest X-rays test were conducted And inflammatory cell counts , serum SAA and CRP levels were measured. SAA were compared among subgroups of asthmatic patients and healthy controls and the diagnostic value of SAA to distinguish bacterial infection-induced asthma was estimated. Results SAA of both asthma subgroups were significantly higher when compared with the healthy individuals, and it was higher in bacterial infection-induced group than that in non-bacterial infection-induced group. In terms of ROC curve , AUC was 0.966 for SAA to distinguish merging bacterium infection, and the cut-off value was 36.67mg/L with sensitivity of 92.3% and specificity of 88.2%. Conclusions SAA increases in patients during acute asthma attack, and particularlymore obviously in bacterial infection-induced patients. It may be used as a reliable biomarker to distinguish merging bacterium infection during acute asthma attack.

The implementation of knowledge management (KM) in hospitals affects efficiency and outcomes of hospitals.However,few studies explored the implementation of KM in China.Twenty-two questions were designed concerning KM implementation status in over 50 hospitals.In order to understand the KM level and attitude to KM of the hospital's managers,a random sampling survey was conducted among 138 managers from 50 different scales of hospitals in 15 provinces of China.The survey showed that overall level of KM implementation in Chinese hospitals was still low and differed among different scales of hospitals (P＜0.05,or P＜0.01).In all the hospitals investigated,63.8％ did not implement KM yet,among which 46％ even had not planned for that.49.8％ of the hospitals investigated had no training program about KM ever and the main source of hospital staff to get knowledge was iuternet.It suggested that hospital managers should make much more efforts to get to know and understand theories on KM,so that hospital KM could be promoted more rapidly.

Objective To observe the survival and reproduction of Oncomelania hupensis snails and their susceptibility to schistosome in schistosomiasis non-endemic area of the Yangtze River estuary in Southern Jiangsu.Methods The soil and water from the Yangtze River estuary of Southern Jiangsu were used for the experiment.The snails reproduced in the same year were collected from the upper reaches of the Yangtze River and raised in the laboratory.The snail survival and reproduction rates and schistosome infection of the snails were observed.The soil collected from schistosomiasis endemic area was used in the control group.Results There was no significant difference between the experimental and control groups for the snail survival rates both in 6 and 12 months (X~2= 0.727 8,P > 0.05 and X~2 = 0.416 1,P > 0.05).Each female snail reproduced 67.69 eggs in average (95 % CI:24.026 0-110.097 4).The average hatchability rate of snail eggs was 83.60%,and there was no significant difference between the 2 groups (X~2= 9.131 8,P > 0.05).The schistosome infection rate of the second generation snails was 1.40% (5/356) 60 days after the infection in the laboratory.Conclusions The snails collected from the upper reaches of the Yangtze River marshland can survival and reproduce in the soil and water from schistosomiasis non-endemic area of the Yangtze River estuary of Southern Jiangsu,and the second generation of the snails can be infected with schistosome in the laboratory.

Objective To investigate the phenotype and genetic characteristics of a Chinese family with an autosomal-dominant inherited sensorineural hearing loss.Methods A Chinese pedigree associated with an autosomal-dominant inherited low-frequency sensorineural hearing loss (LFSNHL) was investigated.After obtaining informed consent from all study participants medical and audiological examination were used to rule out any syndromic hearing impairment.Five patients were tested with DPOAE and ABR,while two patients were tested with vestibular function and computed tomography scan of the temporal bone to exclude auditory neuropathy and other possible aural disorders.Twenty-one loci and twenty-three genes of DFNA screening had been done by using microsatellite markers and linkage analysis.Results Proband of the family had been diagnosed with low-frequency sensorineural hearing loss.A Chinese family BJ-L046 with non-syndromic autosomal dominant hearing loss was ascertained.Hearing impairment in the affected members in family BJ-L046 occured from 10 to 20 years of age and mainly affected the low frequencies,causing an upsloping audiogram.Higher frequencies were getting involved with increasing age,thus causing a flat-type audiogram.No positive result was found in twenty-one loci and twenty-three genes of DFNA screening.Conclusion A Chinese family with late-onset low-frequency sensorineural hearing loss was clinically studied.No positive result was found by linkage analysis,and twenty-one loci and twenty-three genes of DFNA were preliminary excluded.

Two fragments G1 and G2 of the glycoprotein G gene of bovine respiratory syncytial virus(BRSV) were selected for expression in Escherichia coli based on the analysis of glycoprotein G by DNA Star software.Then the two fragments of glycoprotein G were amplified by PCR with synthesized G gene of BRSV as the template.The amplified fragments G1 and G2 are 570bp and 308bp in length,respectively.The PCR products were cloned into pET30a vector and expressed in soluble form in E.coli after induction of cultured E.coli with IPTG.Both of the recombinant proteins G1 and G2 were purified by immobilized Ni ion affinity chromatography under native conditions.Then the purified proteins were analysed by Western blotting.The results showed that the purified recombinant protein G1 retained good antigenicity and specificity.But the purified recombinant protein G2 didn't possess biological activity.Antibodies against BRSV were detected in suspected bovine serum samples in China by using indirect ELISA and Western blotting with the purified recombinant protein G1.The purified recombinant protein G1 might be used as antigen for establishing serological methods for diagnosis of BRSV infection.And the purified recombinant protein G1 might also be used for preparing polyclonal and monoclonal antibodies for research on biological functions of glycoprotein G of BRSV.

AIM: To evaluate the clinical results of capsular tension ring (CTR) implantation in phacoemulsification for eyes with congenital lens subluxation.METHODS: This study comprised 18 patients (31 eyes) with congenital ectopia lentis.All patients received phacoemulsification with CTR and intraocular lens (IOL) implantation.Visual acuity before and after surgery were examined.IOL decentration were measured with Image-Pro Plus image processing software.The complications were also recorded preoperatively and postoperatively.RESULTS: Uncorrected vision of all eyes increased after surgery, and all cases had different degree of IOL decentration after surgery.Two eyes received CTR scleral fixation 3mo after surgery because the IOL decentration aggravated during the follow-up period.CONCLUSION: Phacoemulsification with CTR and IOL implantation is effective and safe for congenital lens subluxation.The implantation of CTR increase the stability of the capsular bag, improve the safety of surgery, and maintain the right position of IOL.CTR scleral fixation is a effective supplement for progressive cases.

OBJECTIVETo evaluate the reliability, validity, and responsiveness of traditional Chinese medicine (TCM) clinical outcomes rating scale for heart failure (HF) based on patients' report.

METHODSTCM clinical outcomes rating scale for HF (TCM-HF-PRO) were evaluated based on 340 HF patients' report from multiple centers. The completion of the investigation was recorded. Cronbach's α coefficient and split-half reliability were used for reliability analysis, and factor analysis was used to assess the construct validity of the rating scale. Pearson correlation analysis was then used for criterion validity analysis. Discriminant analysis was used to assess the responsiveness of the scale. All 340 HF patients having complete TCM-HF-PRO data were assigned to the treatment group and the control group by central randomization. The total TCM-HF-PRO scores of the two groups were compared using paired t-test to reflect the longitude responsiveness of the scale before treatment and at week 2 after treatment.

RESULTS(1) The recycling rate of the scale was 100.0%. One of them was not filled completely, which was rejected thereby. So the completion rate was 99.7%. The completion time for TCM-HF-PRO scale ranged 15 to 25 min. (2) The Cronbach's α coefficient of rating scale was 0.903, split-half reliability was 0.844 and 0.849. (3) Confirmatory factor analysis showed that 7 factors and items formed according to maximum load factor basically coincided with the construct of the rating scale, 7 factors accumulated contribution rate was 43.8%. TCM clinical outcomes rating scale for HF based on patients' report was relatively better correlated with the Minnesota living with HF questionnaire (r = 0.726, P < 0.01). (4) Discriminant analysis showed that the rating scale correctly classified more than 78.8% of case studies having confirmed initial differential diagnosis by experts. The total scale of the rating scale decreased more in the two group after treatment, with significant difference as compared with before treatment (P < 0.01.

CONCLUSIONTCM clinical outcomes rating scale for HF based on patients' report had good reliability, validity and responsiveness, hence it could be used to assess clinical efficacy for HF patients.
