Objective To investigate the clinical characteristics on diagnosis and treatment of renal tubercu- losis.Methods Clinical data of 82 patients with renal tuberculosis were retrospectively reviewed.Results All of the 18 cases who received medication recovered completely.64 cases undergoing surgery were pathologically diagnosed to have renal tuberculosis,of which 2 cases developed ureteral stump syndrome.Conclusion Urine PCR-TB-DNA re- mained the primary diagnostic method before operation.Computed tomography(CT)and magnetic resonance urogra- phy(MRU)could be used in diagnosis of renal tuberculosis.When the non-functioning kidney was resected,per- inephrit fat and the involved ureter should be concomitantly resected as much as possible.

Objective To study the effects of manganese on the expression of caspase-3 and cytochrome-c in the spermatogenic cells of rats. Methods Forty-eight male SD rats were randomly divided into the high dose,low dose exposure groups and the control groups,16 in each,were given manganese(MnCl2?4H2O) at 15,30 mg/kg and normal saline,I.P. once a day, 5 times a week,for 6 consecutive weeks. In the 4th and 6th weekend,the testis were collected,the expression of caspase-3 and cytochrome-c in the testis was determined by immunohistochemical methods (SABC). Results The caspase-3-positive-cell rate in the spermatogenic cells of rats in the high dose and low dose exposure groups increased significantly (P

Objective To establish the method for detemining the content of ephedrine hydrochloride in Zhike Pingchuan Tangjiang by HPLC. Methods Diamonsil ODS1 C_(18) Column was used with acetonitrile -0.1% phosphoric solution (with 0.1% triehylamine) (3 : 97) as the mobile phase, the detection wavelength as 205 nm, and flow rate was 1.0 mL/min. Results The calibration curve was linear at the range of 0.12～ 0.96 ?g for ephedrine hydrochloride and linear equation was Y= 109759X+3792.8, r=0.9998. The average recovery was 98.4% and RSD was 0.87% (n =5). Conclusion This method was simple, accurate and proper, with good reproducibility. It can be used for quantitative analysis of ephedrine hydrochloride in Zhike Pingchuan Tangjiang.

Objective To quantify the changes of tongue color with the development of the disease according to the characteristics of human vision.Methods Psychological scales of tongue color perception were obtained from thc psychophysical experiments.Polynomial regression and support vector regression (SVR) were used to establish the mathematical model between the physical values and the psychological scales of tongue color.Results The psychological scales exported from the model could correspond to the visual perception of tongue color change, and SVR has higher accuracy.Conclusions The psychological scale, can not only quantitatively evaluate the tongue color in the development of the disease, but also quantify the degree of disease, to assist the doctors for disease diagnosis and treatment.

Objective To explore the possibility of anterior open reduction and internal fixation to treat the lower cervical irreducible dislocation. Methods 15 cases of lower cervical irreducible dislocation were treated by the anterior open reduction and internal fixation, 11 cases were male and 4 cases were female, 10 cases were unilateral facet locked and 5 eases were bilateral facet locked which were confirmed by the MRI and CT scan. All the cases were failed to the skull traction before operation and received anterior open reduction and plate fixation, and interver-tebral fusion. All the cases were followed up, the recovery of neurological function and the fusion rate were evaluated. Results 15 cases were completely reduction and none of them got a worse neurological function. Conclusion The treatment effect of anterior open reduction and fixation for the lower cervical irreducible dislocation were good.

Objective To explore the association between infant breastfeeding and cognition and behavior development in school age children.Methods Five hundred and eighty-one children aged 7-11 years old from two schools in Ningyang of Tai′an.Their cognition and beha-vior development during school age were assessed by Ravin's standard progressive matrices and child behavior check list(CBCL).Their feeding conditions during infant period,family environment,education level of parents,et al,were investigated with self-made inventory questionnaire.Association between infant breastfeeding types,duration of breastfeeding and cognition,behavior development were analyzed.Results The single factor analysis showed the scores of perceptual distinction,similarity,and Abstract thought in children who were only breast fed before 4 months were higher than those of controls for male children(Pa

Objective: Tuberous sclerosis complex (TSC) is a multisystem genetic disorder caused by mutations in the TSC1 and TSC2 genes, but the molecular events contributing to TSC are not well understood.However, little is known about the role of microRNAs in TSC.To explore the microRNA differential expression profile between tuberous sclerosis complex cell line TSC2-/-MEFs and normal type cell line TSC2+/+ MEFs, and to provide new clues to study the mechanism of microRNA function in tuberous sclerosis complex.Methods: TSC2-/-MEFs and TSC2+/+ MEFs cell lines were cultured in vitro, each with three samples chosen as the experimental group and the control group respectively.Total RNA was isolated using TRizol and purified with RNeasy mini kit according to manufacturer''s instructions.RNA quality and quantity were measured by using nanodrop spectrophotometer and RNA integrity was determined by gel electrophoresis.Total RNAs were extracted by TRizol, followed by RNA quantification and quality control.MicroRNA profiles were analyzed by microarray and the threshold value used to screen up-regulated more than 2-fold change or down-regulated less than 0.5-fold change compared with controls.Real-time PCR was used to validate the reliability of microarray.Cell counting kit-8 (CCK-8) assay was performed to evaluate the proliferation.Results: Fourteen microRNAs, including miR-18a-5p, miR-376c-3p, miR-136-5p, miR-467c-5p, miR-467b-5p, miR-5104, miR-3098-3p, miR-30a-3p, miR-302b-3p, miR-18a-3p, miR-19b-1-5p, miR-19a-5p, miR-20a-5p, miR-155-5p, were up-regulated, while twenty-six microRNAs, including miR-200b-3p, miR-450a-1-3p, miR-542-5p, miR-199b-5p, miR-10a-5p, miR-466c-5p, miR-450a-5p, miR-450b-5p, miR-542-3p, miR-351-5p, miR-322-3p, miR-199a-3p, miR-335-5p, miR-10b-5p, miR-351-3p, miR-155-3p, miR-497a-5p, miR-503-5p, miR-148a-3p, miR-1843a-5p, miR-199a-5p, miR-490-5p, miR-450a-2-3p, miR-322-5p, miR-214-3p, miR-450b-3p, were down-regulated in tuberous sclerosis complex cell line TSC2-/-MEFs compared with normal type cell line TSC2+/+ MEFs (P<0.05).Real-time PCR confirmed the expressions of miR-136-5p, miR-30a-3p, miR-302b-3p, miR-10b-5p, miR-148a-3p, miR-199a-5p consistent with the microarray data (P<0.05).Furthermore, the overexpression of miR-199a-5p significantly inhibited cell proli-feration (P<0.05).Conclusion: There are differences in the expression of miRNA between the tube-rous sclerosis complex cell line TSC2-/-MEFs and normal cell line TSC2+/+ MEFs.MiRNA-199a-5p plays an important role in tuberous sclerosis complex, which may be developed as an important molecular target for the treatment of tuberous sclerosis complex.
