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 evaluate the effect of free NgR-modified bone marrow stromal cell (BMSC) transplantation on axon regeneration in rats after spinal cord injury. Methods Genes encoding free NgR protein were cloned and transduced into BMSCs at passage 3 using a lentivirus vector.Indirect immunofluorescence was used to detect the expression of free NgR protein.Meanwhile a spinal cord contusion model was established in 36 adult Sprague-Dawley rats at the T10 segment.The rats were then divided randomly into an experimental group and a control group.NgR + BMSCs were transplanted into the injured site 1 week post-trauma in the experimental group.BMSCs were also transplanted at the same time into the control group.Expression of free NgR at the injury site was detected by immunohistochemical staining at 1 week post-transplantation.The functional recovery of both groups was evaluated at 4 and 6 weeks post-transplantation.Longitudinal sections of the spinal cord were studied for axon regeneration using horseradish peroxidase staining. Results Expression of free NgR was found in the cell plasma of BMSCs by indirect immunofluorescence post-transfection.Positive immunohistochemical staining for NgR was found at the transplant site in the experimental group 1 week post-transplantation.Better axon plasticity could be observed in the experimental group.The Basso-Beattie-Bresnahan scoring of the experimental group was significantly higher than that of the controls at both observation times. Conclusions Free NgR-modified BMSCs can prompt injured axons to regenerate and thus to promote the recovery of neurological function.This might provide a new strategy to treat spinal cord injury.

Wnt signaling pathway is not only closely related to tumor invasion and metastasis,such as cancer cells migration and adhesion,extracellular matrix degradation,and angiogenesis,but also plays an important role in self-renewal,proliferation and differentiation of tumor stem cells.Progress has been made in high specific genes drug development and targeted therapy against the Wnt signaling pathway.

[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 analyze the correlation betWeen clinical features at admission and recent prognostic outcome in patients With acute myocardial infarction (AMI).Methods:The data of 108 patients admitted because of primary AMI Were retrospectively analyzed.According to occurrence of major adverse cardiovascular events (MACE)or not after discharge,they Were divided into event group (n=61)and non-event group (n=47).Clinical features such as Gender,age etc.of tWo groups Were collected,analyzed and compared.After one-year folloW-up,correlations betWeen clinical feature indexes and MACE incidence Were analyzed.Results:Compared With non-event group, there Were significant increase in mean age,mean arterial pressure (MAP),left ventricular end-diastolic dimension (LVEDd),percentage of> Killip class 2,Grace score and multi-vessel coronary disease,and significant decrease in left ventricular ejection fraction (LVEF)in event group,P<0.05~<0.01. Single factor correlation analysis indi-cated that age,MAP,LVEF,percentage of > Killip class 2,Grace score and multi-vessel coronary disease rate Were correlated With MACE incidence rate (P<0.05~<0.01);multi-factor Logistic regression analysis indicated that age (OR=0.827),LVEF (OR=0.624),Grace score (OR=0.589)and multi-vessel coronary disease rate (OR=0.461)Were risk factors for MACE in AMI patients,P<0.05 all.Conclusion:Advanced age,loW left ven-tricular ejection fraction,higher Grace score and more multi-vessel coronary disease are high risk factors for recent occurrence of major adverse cardiovascular events in patients With acute myocardial infarction.

Objective To investigate the efficacy and safety of intrathecal chemotherapy combined with concurrent radiotherapy in patients with leptomeningeal metastases from solid tumors.Methods The clinical and follow-up data of 29 patients with leptomeningeal metastases from malignant solid tumor who had intrathecal chemotherapy combined with concurrent radiotherapy were retrospectively analyzed.The treatment regimen was that 12.5-15.0 mg of methotrexate intrathecal injection once a week for 8 successive weeks combined with whole brain irradiation to a total dose of 40 Gy,20 fractions or with lumbosacral spinal canal irradiation to a total dose of 50 Gy,20-25 fractions.Results Nineteen patients completed the concurrent therapy and 19 patients were dead.There were 9 patients with complete remission of symptoms,11 with obvious improved symptoms,6 with alleviated symptoms,and 3 with no relief.All of the 29 patients,were followed up for 0.4-15.0 months.The median survival was 5 months.The 6-month survival rate was 48％ (11/23),excluding 4 patients with follow-up time less than 6 months and 2 patients noncancer deaths.The main toxicities were myelosuppression,methotrexate-related mucositis,chemical nerve root injuries,chemical meningitis,chronic neurotoxicity,seizures,and radiation-related mucositis.The incidence of severe toxicity was 17％ (5/29).Conclusions Combination of intrathecal methotrexate with concurrent radiotherapy can effectively alleviate the symptoms and improve the life quality of patients.The therapy with low incidence of severe toxicity and good tolerance has the trendency to prolong the median survival.

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.
