[Summary] To investigate the association of rs2282679 A/C polymorphism in vitamin D binding protein gene with vitamin D deficiency in 1 216 participants.A standardized questionnaire was applied to collect information on alcohol consumption,smoking habits,and use of medications.Serum 25-hydroxyvitamin D [25 (OH) D] was determined by radioimmunoassay.Vitamin D binding protein genotypes were determined by SNaPshot method.1216participants included 457 women(37.6%),478 (39.3%)with vitamin D deficiency [25 (OH) D<50 nmol/L],and 386 (31.7%) overweight/obese participants.The frequencies of rs2282679 CC,AC,and AA genotypes were 8.7%,41.0%,and 50.3%,respectively.The distributions of genotypes and alleles differed significantly between participants with sufficient vitamin D and those with vitamin D deficiency (P < 0.05).There were significant differences in the serum levels of 25 (OH) D between three genotypes before and after being adjusted for covariates (P<0.01).AA had a 22% (OR =0.78,95% CI 0.65-0.93,P =0.006) lowered risk of vitamin D deficiency compared with the whole studied population.Compared with CC genotype,AA had a 36% lowered risk of vitamin D deficiency(OR =0.64,95 % CI 0.42-0.98,P =0.006),while there was no significant difference between AC and CC genotypes(OR=0.87,95% CI0.57-1.34,P=0.53).In conclusion,the vitamin D binding protein rs2282679A/C polymorphism was significantly associated with serum level of 25 (OH) D and risk of vitamin D deficiency.

Objective To investigate the value of application of magnetic resonance imaging (MRI) in diagnosis and treatment of leptomeningeal metastases from malignant solid tumors.Methods A retrospective analysis was conducted depend on the radiological data of 63 patients who had been diagnosed as leptomeningcal metastasis of malignant solid tumors.Results All patients received brain MRI examination.26 patients underwent cervical or lumbar spine MRI examination.The MRI images showed nodular enhancement in the gyri and sulci,leptomeningeal linear enhancement,dura mater thickening and enhancement,ependymal enhancement,intraventricular metastasis,intraspinal metastatic nodules,communicating hydrocephalus,subdural hydroma and negative imaging.Ncuroimages of ependymal enhancenent,intraventricular metastasis and intraspinal implantation metastasis appeared in 5,7 and 9 patients with small cell carcinoma,respectively,which were higher than that of the other pathological types (P =0.002,P =0.009,P < 0.000 1).Seizure occurred in 7 patients after intrathecal chemotherapy,of which 5 patients had pia mater linear enhancement.Among 33 patients treated with radiotherapy combined with intrathecal chemotherapy,3 patients had poor prognosis,of which 2 patients had negative imaging findings.The conditions of 25 patients were improved obviously after treatment,of which 21 patients showed different imaging remission in MRI re-examination.Conclusions The contrast MRI has an important assistant effect in diagnosis of leptomeningeal metastasis of malignant solid tumors.The MRI findings and clinical features are related with the pathological types.The pia mater linear enhancement indicates a high possibility of seizures after inthathecal chemotherapy,and it suggests that the preventive treatment should be given for such patients.MRI is not applicable to evaluate severity,prognosis and curative effect of the disease.

Objective To analyse the effect of endoscopic thoracic sympathectomy of palma-plantar hyperhidrosis. Methods Between January 2006 and January 2009,77 cases with palma-plantar hyperhidrosis were operated by thoracoscope. Fifty-two cases of palma-axillary-plantar hyperhidrosis were performed sympathectomy of T2-T4 and 25 cases of palma-plantar were performed sympathectomy of T2-T3.Bilateral procedures were completed in the same position. Results After operation palmar hyperhidrosis and armpits hyperhidrosis all were cured. Of soles, 7 cases were completely dry, 34 cases nearly dry, 32 cases unchanged and 4 cases worse. There was no significant difference in the change of plantar hyperhidrosis between sympathectomy of T2-T3 and T2-T4 (P > 0.05). Conclusions Bilateral single port for endoscopic thoracic sympathectomy produces slighter trauma and patients easily accept it. Plantar sweating can be relieved or nearly relieved in partial patients after thoracic sympathectomy. There is no difference in the effect of plantar hyperhidrosis between sympathectomy of T2-T3 and T2-T4.

Objective To analyze inducing factors of acute left heart failure(AHF) of emergency case.Methods According to different age and gender,the inducing factors of AHF of 211 patients were retrospectively analyzed.Results Infection(42.99%) was the most important inducing factors of AHF in all the four age-groups,but as for patients elder 80,the arrhythmias was also play an important part in inducing factors of AHF.The difference of inducing factors was found among the four age-groups.but the difference of inducing factors was not found between the two gender-groups. Conclusion Since the most important inducing factors of AHF of emergency case was infection,anti-infectives is important for preventing and controlling AHF.

Objective To investigate the effects of extract of Ginkgo biloba leaves EGb761 on 1-methy-l 4-phenylpyridium (MPP+)-induced injury in human neuroblastoma SH-SY5Y cells; To discuss its mechanism of action.Methods Cell culture method was used and SH-SY5Y cell damage model was induced with different concentrations of MPP+ to build Parkinson’s disease model in vitro. The experiment was divided into control group, MPP+ model group, low-, medium-, and high-dose EGb761 groups. The survival rate was determined by MTT assay, and the apoptotic rate was detected by flow cytometry according to AnnexinV apoptosis detection kit. The cell morphology was observed by inverted microscope. NO content in SH-SY5Y cells was detected by Nitric acid reduction method.Results Compared with the control group, the survival rate of SH-SY5Y cells decreased and the apoptotic rate and NO content increased in the model group (P<0.05); Compared with the model group, the survival rate of SH-SY5Y cells increased and the apoptotic rate and NO content decreased in the low-, medium- and high-dose EGb761 groups (P<0.05).Conclusion EGb761 can protect MPP+-induced SH-SY5Y cell from damage by the inhibition of the content of NO free radical.
