Objective To investigate the effects of rapamycin on p-JAK2,STAT3,p-STAT3 and PCNA in ranal tissue of IgAN rats.Methods The animal models of IgA nephropathy were devided into control group,IgAN model group,losartan group and rapamycin group.The clinical efficacy of rapamycin,and its influences on the protein and mRNA expressions of STAT3,p-STAT3,p-JAK2 and PCNA were determined by western blot,RT-PCR and immunohistochemical techniques respectively.Results The protein and mRNA expressions of p-STAT3,STAT3,p-JAK2 and PCNA were significantly increased in kidney of IgAN rats(P

OBJECTIVETo establish a general method of focal cerebral ischemia model in different varieties of mice.

METHODEach group of healthy adult KM and C57BL/6 mice were randomly divided into control group (n = 10) and MCAO group (n = 10). The mice in MCAO group were applied in the preparation of the MCAO model by intraluminal occlusion using monofilament. Twenty-four hours after operation,the neurologic function was evaluated,middle cerebral artery blood flow was monitored and the infarction volume was calculated by TTC staining, to evaluate the reliability of the model.

RESULTIn the MCAO group, the base value of the cerebral blood flow down of KM and C57BL/6 mice respectively was (81.65 ± 4.59)%, (83.68 ± 6.25)%. The neurological deficit score respectively was (2.30 ± 0.82), (2.50 ± 0.80). TTC staining can clearly show the infarction area, and relatively stable, 24 hours of the survival rate of KM and C57BL/6 mice were 100% and 80% respectively.

CONCLUSIONThe key link is the optimization and improvement of monofilament, temperature, anesthesia and so on. The modified intraluminal occlusion of MCAO using monofilament is a kind of reliable and simple method to establish experimental cerebral ischemia model in mice.

AIM: To observe the effects of puerarin on blood pressure(BP),serum lipid in a rat model of insulin resistance and the mechanism.METHODS: Adult SD rats were maintained on high-fat-sugar-salt diet for 12 weeks.Puerarin was administered to the rats from 9th week for 4 weeks by intramuscular injection.BP was measured at the end of 0,8th,12th week.The levels of serum glucose,serum lipid,fasting serum insulin and the levels of MDA,TNF-?,plasma rennin,angiotensinⅡ(AngⅡ) and the activity of SOD were measured and the insulin-sensitivity index was also calculated at the end of the experiment.RESULTS: High and middle dosage of puerarin significantly decreased blood pressure,reduced the levels of serum lipid and AngⅡ,and also increased insulin-sensitivity index.The levels of MDA and TNF-? were significantly decreased by high dosage of puerarin.The activity of SOD was increased significantly.CONCLUSIONS: Puerarin possesses the effects of decreasing the blood pressure and serum lipid in a rat model of insulin resistance,which may be concerned with the changes of rennin-angiotensin system,the levels of oxygen-derived free radicals and TNF-?.

?AIM: To study the association of the single nucleotide polymorphism ( SNP) rs1157699 in the calcitonin receptor-like receptor ( CRLR ) gene with primary angle closure ( PAC) in a Han Chinese population.?METHODS: All samples, involved 232 PAC cases and 306 controls, were obtained from an epidemiologic survey conducted in Funing, Jiangsu Province, China. Genotyping were carried out by TaqMan-MGB probe using the real time quantitative polymerase chain reaction system to study the relationship between SNP of rs1157699 in CRLR gene and PAC.?RESULTS: The prevalence of CRLRrs1157699 genotype was 67.4%, 30.0%, 2.6% for CC, CT, TT in cases, and 71.3%, 27.0%, 1.7% in controls respectively.There was no difference between the two groups in the distribution of genotype and allele frequencies of rs1157699 (P>0.05).?CONCLUSION:Our results do not support a significant role for rs1157699 in CRLR with PAC.

To study the pharmacokinetics of ~(131)I-Metuximab injection (Licartin) combined with transarterial chemoembolization (TACE) for treatment of hepatocellular carcinoma (HCC). MethodsLicartin (27.75 MBq/kg) and the mixture of anticancer drug and Lipiodol were sequentially administered with interval of 20 minutes to 15 patients with HCC via a transfemoral catheter.After the Licartin was administrated, the pharmacokinetic and biodistribution data were evaluated through venous blood samples,urine collections,and 4 γ-scintigraphies (SPECT) over 7 days. The pharmacokinetic parameters were determined from integration of the blood radioactivity-time curves using the SPSS 12.0 software. The tumor-no-tumor ratio (T/NT) was calculated by ROI. Absorbed doses in organ were estimated according to the medical internal radiation dose formalism. The biodistribution of licartin within patient's body at different time points was compared for various organs using analysis of variance for repeated measures, as well as the T/NT ratio. ResultsThe blood radioactivity-time curves followed the dynamics two-compartment model, with the major pharmacokinetic parameters including t_(1/2)α(1.96±1.65) h, and t_(1/2)α(19.07±5.91) h,and t_(1/2)β (57.09±10.92) h, and C_(max) 2.113×10~9min~(-1)·L~(-1), and AUC_(0-∞) 1.302×10~(11) h·min~(-1)·L~(-1), respectively. The accumulated urine radioactivity was 52.2% of administrated dosage during 144 h after administration. There were statistical significant difference of biodistribution of licartin and T/NT ratio between organs at different time points (F=6.583, P<0.01 and F=3.546, P<0.01). SPECT scans showed the significant accumulation of the radioconjugate in liver tumor and faint uptake in other organs for 14 days. Tumor-to-liver ratio decreased from 2.88±1.02 at 3 h to 1.64±0.40 at 168 h (n=7). Organ absorbed dose was (3.19±1.01) Gy in liver (n=12) and (0.55±0.09) Gy in red marrow (n=7). ConclusionLicartin combined with TACE for treatment of HCC is helpful to significantly accrete the radioconjugate in liver tumor, and protect normal organs from radiotoxictiy.

OBJECTIVETo evaluate a technique for repairing a large thoraco-abdominal defect after the separation of the thoraco-abdomino-conjoined twins.

METHODSA 8 cm x 5 cm thoraco-abdominal flap on each side of the trunk of the conjoined twins was designed before the separation. The flap from the A-infant was used for repairing the thoraco-abdominal defect of the B-infant while the flap from the B-infant for the defect of the A-infant.

RESULTSBoth of the defects after the separation of the conjoined twins were completely covered by the flaps. The flaps were survival very well with very good appearance.

CONCLUSIONThe above technique could be a good way for repairing the defects after the separation of the thoraco-abdominal conjoined twins.
