Objective To determine the prevalence and influencing factors of urinary calculi,to explore the interIrelationships between urinary stone disease and various risk and protective factors,to determine the potential implications for intervention and prevention in Changsha,and to evaluate the relative importance of each risk factor,with the objective of providing scientific guidelines for urinary calculi prevention and diagnosis. Methods A case-control study was designed,and 66,772 people were surveyed.Ultrasound examination,blood biochemistry,general physical examination,gender and age were asked in a questionnaire to determine a diagnosis of urolithiasis.By means of SPSS software a x2 tendency test and non-condition Logistic regression were conducted. Results A multivariate Logistic regression analyses was conducted.The final factors entered into the model were sex,age,profession,dietary habits,drinking habits,smoking and level of uric acid. Conclusions Hazard factors associated with urolithiasis are male gender,age,profession,dietary and drinking habits,smoking and level of uric acid.

Desmoid tumor also known as aggressive fibromatosis,are rare fibroblastic tumors which are derived from deep fascia planes or muscuofascia structures.Resectable extra-abdominal and abdominal desmoid tumor should always be treated with the aim of achieving a negative margin through wide radical resection with margins above 2 cm.Ifthis is not feasible,function-sparing surgical resection is suggested.Adjuvant radiation should be considered for patients with positive margins,recirrent tumors or unresectable diseases.Intra-abdominal desmoid tumor is common in patients with familial adenomatous polyposis.It has a high recurring rate after surgical resection and therefore a high dosage of tamoxifen and sulindac are recommended as first-line treatment.Due to the variable nature of the outcome and vague reaction to drug therapy,individualized treatments,including the wait and see policy,has been widely investigated and thought to be a promising strategy for the future.

Objective To explore the effect of microsurgery for refractory temporal lobe epilepsy . Methods A retrospective analysis was made in 102 patients with refractory temporal lobe epilepsy from January 2005 to December 2011.The patients received comprehensive preoperative localization , intraoperative frontotemporal pterional incision , and microsurgical resection of epileptogenic focus .The efficacy was evaluated according to the Engel standards .Indications such as self-care ability, learning ability, and working ability were used to evaluate the quality of life , which were recorded and compared before and after operation . Results Follow-up was accomplished in all the 102 cases for a duration of 1 year and 9 months to 7 years.There were no mortality and serious complications .The effects evaluations at 1 year after operation showed complete disappearance of symptoms ( levelⅠ) in 61 cases (59.8%), almost disappearance (level Ⅱ) in 17 cases (16.7%), symptoms improvement more than 75% (level Ⅲ) in 13 cases (12.7%),and ineffective (level Ⅳ) in 11 cases (10.8%), bearing an effective rate of 89.2% (91/102) and a good-and-excellent rate of 76.5%(78/102).At one year and nine months postoperatively , 6 patients could not take care of themselves , 32 patients obtained partial self-care, and 64 patients had complete self-care,as compared with which there were 21 patients, 67 patients, and 14 patients preoperatively, respectively, having significant differences before and after surgery (Z =-7.001, P =0.000). Statistical significances were obtained before and after operation in 67 cases of children and adolescents with learning ability ( Z=-3.747, P =0.000) and in 35 adult cases with working ability ( Z =-2.564, P =0.010). Conclusions Microsurgical treatment is an effective method for refractory temporal lobe epilepsy .Patients ’ quality of life can get significant improvement after surgery.

Objective: To compare the expression levels of FOXP3 mRNA in the peripheral blood mononuclear cells(PBMC) of hepatitis B patients and healthy persons.Methods: Real-time fluorescence relative quantitative RT-PCR was used to determine the FOXP3 mRNA levels in the PBMCs from 25 patients with chronic hepatitis B and 11 healthy subjects.Results:The FOXP3 mRNA levels were significantly higher in the hepatitis B patients than in the normal subjects(P0.05).Conclusion: The high expression of FOXP3 might be an important factor for the persistence of HBV infection.

The glucose-regulated protein78 (GRP78) is a member of the heat-shock protein 70 (HSP70) family and responsible for cellular homeostasis. GRP78 is highly expressed in various tumors. It plays an im-portant role in tumor proliferation, survival, metastasis, and drug resistance. Suppression of GRP78 in tumors could enhance cancer treatment. Inhibition of GRP78 in tumors may provide a noval approach toward cancer therapy.

Objective To evaluate the applied value of MSCT lung volumes measurement in diagnosing chronic obstructive pulmonary disease(COPD).Methods 40 patients clinically diagnosed with COPD and 26 healthy volunteers as control group underwent MSCT chest CT scanning . The relevant indicators of lung volumes were measured and calculated in comparison with the indicators of clinical lung function . The accuracy and sensitivity of every indicator of lung volumes in forecasting and screening COPD by using ROC curve method were evaluated.Results There were significant differences between the control group and the COPD group in the full expiration volume(Vex),the full inspiration volume(Vin),Vex/Vin and the ratio of the change of lung volume(P

[Objective] To observe the structure characteristics of nano decalcified bone matrix(DBM)produced by MICROS super fine mill,and to study the nano-technologies of DBM and the biocompatibility of nano-DBM as bone graft substitutes.[Methods]Improved Urist method was used to produce DBM.The pieces of DBM was pre-porphyrizated by liquid nitrogen frozen ball mill equipment.The DBM powder were further porphyrizated by MICROS super fine mill to be nano-DBM.The structure of nano-DBM was observed by electron microscope.The experiments on acute toxicity,pyrogen and hemolysis were performed according to theTechnical Evaluation Standards of Biomedical Materials and Medical Instruments promulgated by Chinese Ministry of Health.[Results]The DBM was porphyrizated to the size of 50-200 nm in diameter.No toxicity,pyrogen nor hemolysis of nano-DBM was noted.Nano-DBM exhibited excellent biocompatibility.[Conclusion]Nano-DBM produced under the conditions of low or controlled temperature,is a kind of biomaterial which is avirulent,nonirritant,nonpyrogenic,nonimmunological reaction and reveals good biocompatibility.
