Objective To investigate the related factors analysis of hepatitis B liver cirrhosis with secondary glucose metabolism disorders.Methods 184 patients with hepatitis B liver cirrhosis were selected as the research object and were given 75g oral glucose tolerance test( OGTI),then they were divided into three groups[ normal glucose tolerance(NGT) group,impaired glucose tolerance and impaired fasting glucose regulation impairment(IGR) group,diabetic( DM ) group ] according the results.The general information,laboratory examination and viral load of three groups were compared.Results ( 1 ) The difference of age,waist size,weight,body mass index data and hepatitis B virus load in IGR group and DM group compared with NGT group were statistically significant difference ( all P ＜0.05 ),IGR compared with DM group,all index comparative differences were not significant (all P ＞ 0.05 ).(2)As the aggravating of glucose metabolism disorder,the positive rate of HBsAg,HBeAg and former S1 antigen of NGT group,IGR group and DM group were gradually raised ( all P ＜ 0.05 ).Conclusion The body mass index and hepatitis B virus load are relatively independent risk factors of secondary glucose metabolism disorders in patients with hepatitis B liver cirrhosis,and which are positive correlation with it.However,gender,age,blood lipids are not obvious correlation with secondary glucose metabolism disorders.

Objective To investigate the correlation factors of liver injury in infectious mononucleosis(IM).Methods One hundred and seventy-five IM patients were divided into two groups:IM with liver injury(patient group,85 cases)and IM without liver injury(control group,90 cases).Single factor and multiple factor analysis were completed by unconditional Logistic regression.Results Single factor analysis results showed that there were significance differences between the two groups in age(≥6 years old),male,course of disease,severe disease(involving ≥ 2 organs),heating time,the peak temperature,white blood cell(WBC)and C reactive protein(CRP),CD4+,CD8+,CD4+/CD8+,Epstein-Barr virus(EBV)-capsid antigen(CA)-IgM antibody positive and increased erythrocyte sedimentation rate(ESR)(P＜0.05).Age(≥ 6 years old),male,course of disease,severe disease(involving ≥2 organs),heating time,the peak temperature,WBC,CRP,CD8+,EBV-CA-IgM antibody positive and increased ESR showed positive correlation with IM combined with liver injury,and CD4+,CD4+/CD8+ showed negatively correlated with IM combined with liver injury.Multiple factor analysis results showed that severe disease(involving ≥2 organs),CD8+ high levels were independent risk factors for IM combined with liver injury,and CD4+ high levels and CD4+/CD8+ high were protection factors for IM combined with liver injury(P＜0.05).Conclusions Severe disease(involving ≥2 organs),CD8+ high levels are independent risk factors for IM combined with liver injury,and CD4+ high levels and CD4+/CD8+ high are protection factors for IM combined with liver injury.Therefore,immune modulators should be used to intervene the above factors when patients are treated with antiviral drugs.

The effects of zinc on collagen synthesis and wound healing were observed in 124 rats. The animals were divided into three groups. ZD--zincdeficient, SP--pair fed with zinc supplemented and SF---ad lib withzinc supplemented, each receiving 0.07, 0.82 and 0.84 mg Zn per rat per day respectively. An 8 cm long surgical incision was made on one side of the back of each animal and 3 pieces of sponge were implanted subcutaneous^ on another side. The results showed that the rats receiving zinc supplement (SP , SF) had greater increase of body weight and higher concentration of serum zinc than the ZD rats before and after operation, Tke fibroblast counts in granular tissues of group ZD were significantly less than that of groups SP and SF from the 4th to 14th day after operation. The breaking strength of healing incision of groups S P and SF was greater than that of group ZD in the late stage of wound healing. The determination of sponge collagen indicated that groups SP and SF had stronger ability to synthesize collagen after being wounded than ZD animals. The results suggested that zinc might play an important role in wound healing, not only due to the increase of diet intake, but also due to increased fibroblast proliferation and collagen synthesis.

Objective To investigate the effect of CDH1 3'-UTR + 54C/T single nucleotide polymorphism(SNP) on expression of luciferase reporter gene and its association with susceptibility to cervical cancer. Methods The luciferase gene expression vectors containing CDH1 3'-UTR +54C/T SNP C or T allelotype were constructed. The effect of CDH1 3'-UTR + 54C/T SNP on expression of luciferase reporter gene in 293 T cells were tested by daul lucfferase reporter assay system. The CDH1 3'-UTR + 54C/ T SNP was genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis in 280 cervical cancer patients and 330 healthy controls. Results The lucfferase activity analysis showed that the relative luciferase activity (RLA) of 293T cells with C allelotype was 1.46, which was significantly lower than that of the 293 T cells with T allelotype (3.01; t=2. 94, P =0. 042). There was no significant difference in age distribution between the cervical cancer patients and the healthy controls. The genotype frequency distribution of CDH1 3 '-UTR + 54C/T SNP in healthy controls did not significantly differ from that expected by Hardy-Weinberg equilibrium (P>0.05). The C allelotype frequency of CDH1 in cervical cancer patients was 80. 7%, which was significantly higher than that in healthy controls (74. 5%;χ2 =6.59, P=0.010). The T/T, T/C and C/C genotype frequencies of cervical cancer patients and healthy controls were 4. 3%, 30. 0%, 65. 7% and 5. 8%, 39. 4%, 54. 8%, respectively, which were significandy different (χ2=7.45, P =0.024). Compared with individuals with T/T or T/C genotypa, individuals with C/C genotype had significantly higher risks of developing cervical cancer (OR = 1. 578,95%CI=1.136 -2.191). Conclusion The C allelotypa of CDH1 3'-UTR + 54C/T SNP might decrease the expression of lucfferase reporter gene and the C/C genotypa might be a potential risk for cervical cancer development.

0.05).Conclusion The serum cTnT is not useful for diagnosing the severity of anthracycline induced cardiactoxicity.

Objective: To study the effects of different niacin nutritures on behaviors of stressed rats. Methods: 100 Wistar male rats were assigned into 10 groups:control, pair-fed, nicotinamide (NAM) deficiency (ND), low-dose NAM supplement (LNS 40 mg/kg diet) and high-dose NAM supplement (HNS 500 mg/kg diet), and the corresponding restrained groups. 24 h urinary excretion of N1-methylnicotinamide (NMN), body weight changes, behaviors in the open-field test, plasma cortisol, nitric oxide(NO) and liver nitric oxide synthase(NOS) were determined. Results: Compared with the control group, restrained rats had relatively lower urinary NMN. Both ND and restrainted stress retarded the body weight gains . Rats in the control and LNS groups had relatively shorter latency time in the open-field test. Restrained rats had higher plasma cortisol and NO than those in the corresponding control group. However, rats with HNS had the lowest plasma cortisol concentrations. Dietary supplement of NAM increased liver NOS . Conclusions: Restraint stress may increase niacin depletion and appropriate NAM supplement has positive effects on stress adaptation in rats.

Objective:To study the effects of zinc deficiency on bone histomorphometric parameters of femoral distal diaphysis in rats. Methods:Thirty Wistar rats were randomly allocated into three groups:the zinc-deficient group(ZD), the control group(Cont),and the pair-fed group(ZP). After the rats had been fed for eight weeks, the histomorphometric and dynamic parameters of the rats were analysed using bone histomorphometric method. Results:The number, volume and connectivity of trabecular bone, and the mean trabecular plate density of ZD rats were significantly decreased, but their mean trabecular plate space was significantly increased. In addition, the data showed that ZD animals had significantly decreased trabecular osteoid surface, reduced velocity of bone formation as compared with Cont and ZP animals. The results showed that in ZD rats the mineral deposit rate was significantly slow, while the mineralization lag and osteoid maturation period were obviously prolonged. Conclusion: Zinc deficiency reduces velocity of bone formation and prolongs bone mineralization and destroys bone structure.

One of the core tasks assigned to clinical teachers is to enable students to accurately assign a diagnostic label.The strengths and weaknesses of different approaches to clinical reasoning will be examined using one of the core divides between various models of analytic versus non-analytic as an orienting framework.Clinical teachers should stress the importance of both forms of reasoning,thereby enabling students to marshal reasoning processes in a flexible and context-specific manner.
