Objective To establish a rat model of glioma for MRI study.Methods Fischer 344 rats were inoculated with F98 glioma cells in caudate nucleus by stereotaxic procedure.MRI scanning and pathology examination were performed to observe the tumor growth on 6,8,10,12,and 14 d, respectively,after inoculation and their survival was also analyzed.Results After inoculation,tumors were found in all rats by MRI as early as 6 days.Most of rats died on 14 d after inoculation.The volume of tumor increased as the inoculation time lengthened.The tumor volume measured by MRI was larger than actual size by autopsy,but the both correlated positively(r=0.91,P

Aim The effect of tetrandrine on TGF-?1 mRNA expression in glomerulosclerosis rat was observed. Methods The rats were randomly divided into four groups, such as the normal control group (sham operative rat), glomerulosclerosis model group,tetrandrine group and amlodipine group. The expression of TGF-?1 mRNA was analyzed by Northern blot hybridization. Results The expressions of TGF-?1 mRNA in two treating groups were much lower than untreated model group. There were no difference between these two treating groups. Conclusion Tetrandrine can decrease the expression of TGF-?1 mRNA in glomerulosclerosis rat induced by unilateral renctomy plus adriamycin.

OBJECTIVETo explore the distribution rules of proximal and distal focus of muscle meridian region in scapulohumeral periarthritis.

METHODSThree hundred and six shoulder joints of affected side were selected in 216 patients of scapulohumeral periarthritis. Under the guidance of muscle meridian theory, with the anatomical characteristics of muscle meridian focuses, the frequency and location where proximal and distal focus appeared were calculated by palpation.

RESULTSThe percentages of the frequency that the focus of muscle meridian of Hand-Yangming, Hand-Shaoyang, Hand-Taiyang, and three yin meridians of hand appeared at proximal points of shoulder joint were 25.6% (1 146/5 657), 30.9% (1 749/5 657), 19.0% (1 075/5 657), and 24.5% (1 387/5 657), respectively, the focuses of muscle meridian region were Jianyuci, Juguci, Xiaoshuoci, Naohuici, etc. The percentages of the frequency that the focus of muscle meridian region appeared at distal points of shoulder joint were 31.77% (287/905), 23.2% (210/905), 10.9% (99/905), and 34.1% (304/905), the focuses of muscle meridian were Yangxici, Shousanlici, Yangchici, etc.

CONCLUSIONThe location and frequency of proximal and distal focus of muscle meridian in scapulohumeral periarthritis are closely related with the anatomical structure and biomechanical characteristics of the shoulder joints, thus new therapy for scapulohumeral periarthritis is implied.

BACKGROUND:The traditional method of preparing tissue-engineered conduit has the defects of complex shape manufacturing and uncontrolable inner space structure, which cannot meet the requirements of some micro-catheters.
OBJECTIVE:To prepare a bionic spinal catheter and analyze its performance.
METHODS:The data model of the conduit was established using Solid Works software, and platform scan path was generated onthree-dimensionalprinter to produce the bionic spinal catheter with fibroin and colagen as raw materials. Then the water absorption, porosity, mechanical properties and celular compatibility of the conduits were detected. Next, the conduits were implanted into the subcutaneous tissue of rats and taken out at 1, 2, 3 and 4 weeks after surgery, respectively, to observe the degradation.
RESULTS AND CONCLUSION:The porosity of the conduit was (53.6±1.0)%, the water absorption was (1347±19.4)%, and the compression modulus was (0.60±0.12) MPa. The micropores distributed uniformly with different size ranging from 10 to 240 μm. Spherical or fusiform stem cels survived in the pores and densely adhered to the conduit with pseudopodia. The degradation rate ofthe conduit was 20%, 59%, 74%and 100% at 1, 2, 3 and 4 weeks after surgery, respectively. These findings indicate that the artificial bionic spinal catheter has good biocompatibility and degradability.

Objective To study the risk factors of hemorrhagic fever with renal syndrome (HFRS) in children and adolescents in Xi'an City.Methods HFRS laboratory confirmed cases aged under 16 from January 2013-December 2015 were selected,which were reported by Information System of Disease Prevention and Control of the People's Republic of China.A 1:1 matched case-control study was adopted to retrospective investigate the risk factors.Logistic regression analysis was used to analyze relationships between various factors and HFRS in single factor analysis,the influence factors in the single factor analysis with statistical significances were further analyzed in the multiple factors analysis.Results Eighty-eight matched pairs were investigated.Single factor Logistic regression analysis found that non-nuclear family [odds ratio (OR) =20.25,95％ confidence interval (CI):2.32-76.80],less hand washing frequency before meals (OR =3.67,95％CI:1.40-9.62),the river or pond around the place (OR =1.55,95％CI:1.32-2.94),sit on the hay and play (OR =1.36,95％CI:1.17-1.80),eating in the snack bar (OR =8.33,95％CI:1.78-9.47),do not spray water when sweeping the floor (OR =2.22,95％CI:1.24-4.12),living in the edge of village (OR =1.55,95％CI:1.32-2.94),and keeping pets in the home (OR =12.00,95％CI:1.12-28.84) were associated with HFRS.In multiple factors Logistic regression analysis,risk factors according to the contribution value from high to low in the order were keeping pets in the home (OR =5.40,95％CI:1.78-16.32),less hand washing frequency before meals (OR =3.96,95％CI:1.89-7.23),living in the edge of village (OR =2.42,95％CI:1.82-5.50),and the river or pond around the place (OR =2.21,95％CI:1.86-2.49).Conclusion Risk factors as keeping pets in the home,less hand washing frequency before meals,living in the edge of village,the river or pond around the place are likely risk factors of HFRS.

Objective To determine the effects of gutter oil on liver function,renal function and serum lipid metabolism in mice.Methods A total of 72 mice were averagely divided into 6 groups.Mice were gavaged with different dosages (5 μL/g,1 0 μL/g and 20 μL/g)of gutter oil or cooking oil every other day for continuing 8 weeks.The indexes of liver, kidney and serum lipid parameters were assayed.Results The moisture,acid value and peroxide value of the gutter oil exceeded the national standard.After continuing 8 weeks'intake of oils,alanine aminotransferase (ALT)of gutter oil group with a dosage of 5 μL/g,as well as aspartate aminotransferase (AST)of gutter oil group with a dosage of 1 0 μL/g significantly increased (P <0.05),compared with the cooking oil group.Serum creatinine (Scr)of the gutter oil groups with 3 dosages significantly increased compared with the control groups (P <0.05 ).Meanwhile,blood urea nitrogen (BUN)of gutter oil groups with a dosage of 5 μL/g and 1 0 μL/g were also significantly increased respectively(P <0.05). However,no significant differences were observed in triglyceride (TG)and total cholesterol (TC)among the groups. Conclusion Eight weeks'intake of gutter oil could cause the damage to liver and renal functions.
