Case discussion is an effective approach,which combines basic theory with clinical medicine.It can evoke students' interest and cultivate their creative thinking capacity.Moreover,it can improve teachers' general ability in teaching pathophysiolo- gy.In this article,we discuss the application of case discussion in pathophysiology teaching.

OBJECTIVE: To study the effects of electroacupuncture and diet adjusting on insulin resistance in rats with nutrition obesity, and the role of electroacupuncture and diet adjusting in the treatment of obesity. METHODS: Obesity was induced in rats by high-fat diet. Rats with nutrition obesity were randomly divided into high-fat diet (HD) group, high-fat diet plus electroacupuncture (HA) group, normal diet (ND) group and normal diet plus electroacupuncture (NA) group, with another group of SD rats as normal control (NC). After 15 days, all the rats' body weight and length were measured, the Lee's index was calculated, and the levels of total cholesterol (TC), triglycerides (TG), free fatty acid (FFA), fasting plasma glucose (FPG), fasting insulin (FINS) and tumor necrosis factor-alpha (TNF-alpha) were detected. RESULTS: Compared with the HD group, food intake, body weight and viscera fat weight of the rats with nutrition obesity in the HA group and the NA group were markedly reduced (P<0.05). The levels of blood serum TC, FFA and IR index in the NA group were obviously lower than those in the HD group (P<0.01). The levels of TNF-alpha and FINS in the NA group were lower than those in the HD group (P<0.05). CONCLUSION: Electroacupuncture plus diet adjusting can decrease the levels of serum TNF-alpha and FINS of the obesity rats, and improve the state of insulin resistance.

Objective To screen proteins binding with interferon?(IFN?)from human hepatic cDNA libraty by yeast-two hybrid technique.Methods The IFN?gene was amplified by polymerase chain reaction(PCR)and constructed into pGBKT7 vector as the bait plasmid in yeast-two hybrid system3,pGBKT7-IFN?was then transfected into yeast AH109.The transfected yeast were mated with yeast Y187 containing liver cDNA library plasmid in 2?YPDA medium.Diploid yeast was plated on synthetic dropout nutrient medium(SD/-Trp Leu-His-Ade)and synthetic dropout nutrient medium(SD/-Trp-Leu-His-Ade)containing X-?-gal for selecting.After plasmid extracting and en- zyme cutting analysis,the blue colonies were performed sequence analysis,the results were analyzed by bioinformatics.Results IFN?gene was successfully cloned and expressed in yeast cells.Thirty- four positive colonies were obtained using yeast-two hybrid technique.After sequence analysis,eight clones were found may have a binding effect with IFN protein.Conclusions IFN?genes was success- ful cloned and eight proteins that could bind with IFN?protein were also screened.

Objective To investigate the influence of preterm premature rupture of membranes (PPROM) on neurological development of preterm infants.Methods The preterm infants were classified into 2 groups( PPROM group and control group).The neonatal behavioral neurological assessment (NBNA) and CDCC of infants in two groups were measured and compared after retrieved:gestational age 40 weeks,3 months and 6 months.Results Psycho-moter developmental index(PDI) of PPROM group after retrieved gestational age 3,6 months was significantly lower than that of control group(Pa

Objective To assessed the distribution of two single nucleotide polymorphism (SNP)loci (rs2383206.rs10757278)on chromosome 9p21 in Xinjiang Uygur and Han nationality populations,and to investigate correlation and the incidence of all cases of macrovascular disease (coronary artery disease,carotid atherosclerosis and peripheral arterial disease)and analysis of risk factors.To further study the correlation between the incidence of two single nucleotide polymorphism (SNP)loci (rs2383206.rs10757278)on chromosome 9p21 in type 2 diabetes melli-tus(T2DM)of Han and Uygur ethnic and the incidence of all cases vascular disease,then to analysis the risk factors. Methods 497 adults with T2DM who were treated in the Endocrinology department in hospital from May 2012 to April 2014 were involved in this study,including 298 Uygur patients and 199 Han patients.215 non -T2DMpatients who were treated in the Cardiology department in hospital were also involved in the study,including 93 Uighur patients and 122 Han patients.Then the total 712 patients were detectedby using PCR -SNP Stream technology to analyse rs2383206.rs10757278 loci SNP genotyping.The relevant results were compared with t test,two different genotype distribution and allele frequency were compared with χ2 test,multiple factors analysis were calculated by Logisitic regression.Results The distribution of genotype with two SNP loci had no significant difference between the patients in Uygur group and Han group (rs2383206χ2 =5.570,P =0.062;rs10757278 χ2 =2.721,P =0.257 ),and there's no significant difference between the patients with macrovascular disease and non -macrovascular disease in all patients(rs2383206χ2 =0.120,P =0.950;rs10757278 χ2 =1.027,P =0.598).Logisitic regression analysis showed that the incidence of macrovascular was significantly associated with increasing age(χ2 =28.820,P =0.000)and fatty liver(χ2 =5.210,P =0.020)in Uighur group with type 2 DM.In Han group with type 2 DM,the macrovascular was significantly associated with the increase of age (χ2 =19.980,P =0.000),elevated fasting blood glucose (FPG)(χ2 =4.070,P =0.044)and poor controlled with glycosylated hemoglobin (χ2 =4.280,P =0.040). Conclusion This study found that there's no correlation between two single nucleotide polymorphisms (SNPS)loci (rs2383206.rs10757278)on chromosome 9 p21 large with macrovascular in Uygur group and Han group.Increasing age,higher FPG and poor controlled with glycosylated hemoglobin combined with fatty liver were the risk factors for macrovascular.

In this study, UPLC-MS/MS was adopted to determine the contents of five ephedrine alkaloids (Norephedrine, Norpseudoephedrine, Ephedrine, Pseudoephedrine, Methylephedrine) in plasma and urine in rats after the combined administration of Ephedrae Herba-Gypsum Fibrosum and calculate relevant pharmacokinetic parameters, in order to discuss the effect of the combined administration of Ephedrae Herba-Gypsum Fibrosum on plasma pharmacokinetics and urinary excretion characteristics. According to the results, after being combined with Gypsum, the five ephedrine alkaloids showed similar pharmacokinetic changes, such as shortened t(max), accelerated absorption rate, but reduced AUC(0-t) and V(z)/F, which may be related to the increase in urine excretion. Besides, Gypsum was added to enhance C(max) of Pseudoephedrine and prolong MRT(0-t) of Methylephedrine, so as to enhance the anti-asthmatic effect of Ephedrae Herba and resist the toxic effect of Norephedrine and Ephedrine. This study proved the scientific compatibility of Ephedrae Herba-Gypsum Fibrosum and provided a reference for studies on the prescription compatibility regularity and relevant practices.

Objective To evaluate the clinical significance of bladder saline perfusion before catheter removal in TURP patients. Methods From 2009 to 2011,140 patients received TURP were enrolled in this study.Patients were divided into perfusion group (70 cases with bladder saline perfusion before catheter removal) and control group (70 cases without perfusion). Results Comparing with the control group (33.1 ± 5.4) min,the time waiting for urination was shorter in perfusion group ( 3.7 ± 0.2 ) min ( P ＜0.05 ).The recovering time to normal urination was shorter in perfusion group (7.7 ± 1.2 ) d than in control group (11.7 ± 1.3) d (P ＜ 0.05 ) as well.In the first urine after catheter removal and first urine on the next day morning,white blood cell count of 2 groups (4.5 ± 0.1 ) vs ( 6.9 ± 3.5 ) ; ( 3.7 ± 0.2 ) vs (4.3 ±0.5) had significant differences ( P ＜ 0.05 ). Conclusion Bladder saline perfusion before catheter removal in TURP patients is simple and effective for the restoration of normal voiding.

Objective To investigate the clinical effect of IFNα combined with mannan peptide in treatment of patients with HBeAg-positive chronic hepatitis B ( CHB ). Methods Eighty HBeAg-positive CHB patients with HBV DNA quantity ranging from 10 to 10 eopies/mL were enrolled and randomized into the treatment group and the control group ( n = 40 for each ). Patients in treatment group were given daily subcutaneous injection of IFNα-2b 5,000,000 U for 52 weeks, and received mannan peptide 10 mg per intravenous injection or 2. 5 mg per intramuscular injection for a total of 2 to 3 treatment courses (12 weeks for each). The control group received only IFNα-2b treatment. Liver function, serum markers of hepatitis B, HBV DNA quantity and blood tests were performed before the treatment and at 2, 4, 8, 16, 26 and 52-week during the treatment; and the adverse effects were recorded. Results The rates for ALT normalization, negative HBsAg, negative HBeAg, HBeAg seroconversion and negative HBV DNA were 91. 8% , 17. 5% , 52. 5% , 27. 5 % and 47. 5% at 52nd week in the treatment group, while those in the control group were 80. 0% , 12. 5% , 30. 0% , 10. 0 % and 25. 0% , respectively. There were significant differences in HBeAg-negative, HBeAg-seroeonversion and HBV DNA-negative rates between two groups (χ2 = 4. 178, 4.021 and 4.381, P < 0. 05 ) , and these indexes in the treatment group were increased to 57. 5% , 30. 0% and 50. 0 respectively at 52nd week after drug withdraw. White blood cells began to be elevated at 4th week and were restored to the normal levels at 8th week in the treatment group, while the count in the control was lower than the normal value even at 52nd week of the treatment with the average of (3.45±1. 18)×109/L. Conclusion Alpha-interferon combined with mannan peptide therapy is effective for patients with HBeAg-positive CHB, which may restore the declined peripheral WBC counts induced by interferon and improve the compliance.
