Objective To investigate the effect of postoperative TSH suppression on bone mineral density (BMD) in postmenopausal women with DTC.Methods Postmenopausal women with postoperative DTC underwent thyroid residual ablation or 131I treatment for metastases at Xin Hua Hospital between September 2009 and December 2014 were enrolled and followed for 2 years.They were divided into suppressive TSH group (median TSH＜0.30 mU/L;group 1) and non-suppressive group (median TSH≥0.30 mU/L;group 2).Lumber 1-4 BMD levels (T scores) were measured by a dual energy X-ray absorptiometry bone densitometer at baseline,1 year and 2 years after treatment.All patients had calcium and vitamin D supplementation after TSH suppression.The T scores were compared with Mann-Whitney u test and Kruskal-Wallis test.Results A total of 126 patients were enrolled and followed up for 2 years,including 65 with average age (57.65±6.65) years in group 1 and 61 with average age (56.19±7.17) years in group 2.The T scores in group 1 and group 2 at baseline were-1.70(-2.30,-0.55) and-1.30(-2.10,-0.30) (z=-1.660,P＞ 0.05).The difference of T scores was significant in group 1 at baseline,1-year follow-up and 2-year follow-up (-2.25(-2.48,-0.83),-1.95(-2.70,-0.60);H=6.244,P＜0.05),but not significantly different in group 2 (H=1.102,P＞0.05).The T values were different between the 2 groups both in 1-year follow-up and 2-year follow-up (z values:-2.170,-2.160,both P＜0.05).Conclusions TSH suppression significantly increases the risk of postoperative osteoporosis.The BMD should be followed up annually in postmenopausal DTC patients.

The uhrastructure and atrial natriuretic peptide(ANP)mRNA in myocardium of streptozotocin-induced diabetic rats were studied along with the effect of rosiglitazone.It was found that the myocardial ultrastructure was demaged in diabetic rats.Rosiglitazone may ameliorate the lesion in myocardium,and lower the ANP mRNA in diabetic rats(1.14?0.05 at 6 weeks and 1.12?0.09 at 10 weeks vs 0.97?0.14,both P

Objective To investigate the clinical efficacy of Loewenstein Occupational Therapy Cognitive Assessment (LOTCA) battery for patients at the early stage of traumatic brain injury (TBI). Methods 72 patients with TBI hospitalized from January, 2013 to October, 2014 and 30 healthy controls matched gender, age and educational background were assessed with the Chinese version of LOTCA battery and Mini-Mental State Examination (MMSE) respectively. Results The score of MMSE and LOTCA were correlated (r=0.56, P<0.01). Compared with the controls, the scores of all the subtests of LOTCA decreased (P<0.01) in the patients, especially the orientation, visuomo-tor organization and thinking operation;with the more incidence of medium and serious dysfunction of all the subtests of LOTCA except perception (P<0.01), in which thinking operation was the most and attention was the least. The area under the receiver operating curve (ROC) was (0.84±0.04) in LOTCA, less than that of (0.91±0.03) in MMSE (P<0.05). Conclusion Cognition is widely impaired in patients after TBI, most involved thinking operation. LOTCA is less effective to identify cognitive dysfunction than MMSE, and can be used as an al-ternation or a supplement.

OBJECTIVETo evaluate the effectiveness of manual therapy and traction for lumbar disc herniation and analyze the current status of this kind of randomized clinical trial (RCT).

METHODSDatabase of CNKI, VIP, WANFANG, PubMed and OVID were searched. Some relevant journals were manually retrieved. A total of 2 874 literatures on manual therapy and traction for lumbar disc herniation were collected, of which 17 articles met the inclusion criteria. The Jadad score scale was used to evaluate the quality,and RevMan5.0 was used for meta-analysis of literatures.

RESULTSThe results of the meta-analysis of all trials involved were as followed:the combined effect of the effective rate was RR = 1.10, 95% CI [1.06, 1.14], the combined effect of the cure rate was RR = 1.36, 95% CI [1.21,1.52], the combined effect of the VAS was RR = 1.37, 95% CI [1.28, 1.45], the combined effect of the JOA was RR = 4.75, 95% CI [4.40, 5.09].

CONCLUSIONThe overall quality of the current RCT researches about manual therapy for lumbar disc herniation was lower,and did not support the conclusion that manual therapy was more effective than traction for lumbar disc herniation.

Objective To characterize the dimerization and the antigenicity of the ORF2 polypep-tide of hepatitis E virus (HEV, genotype 4). Methods HEV ORF2 gene was cloned from the serum of a patient with hepatitis E. The genotype was determined by sequencing. Three ORF2 polypeptides differing in size and other polypeptides with point mutations were produced in E. coli. The recombinant polypeptides were purified and analyzed by SDS-PAGE and Western blot. Results The ORF2 polypeptide containing 459-607 amino acid formed homedimer even in 8 mol/L urea. The truncated polypeptides containing amino acid 472-607 or 459-594 formed monomer only. The mutations at amino acid 562 or 595 disrupted the ho-modimer, whereas the mutations at amino acid 476 or 580 did not. Anti-HEV from hepatitis E patients only reacted with the homodimer form of the polypeptide 459-607 and did not react with monomer or tnmcated pol-ypeptides. Conclusion The amino acid 459-607 of HEV ORF2 is essential for dimerization of the ORF2 polypeptide. Residues at amino acid 562 and 595 are critical for the dimerization. The antigenicity of the polypeptide 459-607 mainly depends on its homodimer form.

Objective To compare the validity of Montreal cognitive assessment (MoCA) versus mini-mental state examination (MMSE) in screening cognition impairment in elderly patients with cranio-cerebral trauma.Methods Cognitive function in 40 elderly patients with cranio-cerebral trauma and 40 healthy elderly individuals were assessed by MoCA and MMSE.Receiver operating characteristic (ROC) curve analysis were performed to determine the optimal sensitivity and specificity of MoCA and MMSE.Results The total score and all the sub-test scores of MoCA were much lower in cranio-cerebral trauma patients than in the control group (all P＜0.05).The total score and orientation,calculation,recall,language sub scores of MMSE were significantly decreased in the elderly patients with cranio-cerebral trauma as compared with those in the controls (P＜0.05),while there were no significant differences in the immediate memory and language scores between the two groups (both P＞0.05).The area under the receiver operating characteristic curve showed that MoCA (0.92±0.03) ＞ MMSE (0.74±0.06) (Z=2.460,P＜0.01).When screening the cognition impairment in elderly patients with cranio cerebral trauma,the best cut-off scores of MoCA and MMSE were 24.5 and 27.5 respectively.Conclusions Cognition impairment is decreased in elderly patients with cranio cerebral trauma.The MoCA is superior to the MMSE as a screening instrument in detecting cognition impairment in elderly patients with cranio-cerebral trauma.

Objective To revise the Symptom Distress Scale for postoperative patients with pituitary tumor and to test its reliability and validity. Methods On the base of previous qualitative interview and literature review, Delphi consultation was performed to identify items of the Symptom Distress Scale for postoperative patients with pituitary tumor. By convenience sampling method, totally 191 patients from four first-class ternary hospitals in Jiangsu province were investigated effectively by this scale. Results A scale of 4 factors and 16 items was identified by expert interviews, item analysis, exploratory factor analysis and the four factors could explain 69.812%of the variance. The Cronbachαcoefficient of the scale was 0.920, the content validity index was 0.915, and the interrater reliability was 0.860. Conclusions Symptom Distress Scale for postoperative patients with pituitary tumor has good reliability and validity to assess the symptom distress of pituitary tumor patients after operation.
