Metabolic related fatty liver disease(MAFLD) is a kind of fatty liver disease caused by metabolic dysfunction closely related to insulin resistance and genetic susceptibility, also known as nonalcoholic fatty liver disease (NAFLD). Chronic hepatitis C (CHC) is a worldwide curable viral hepatitis caused by hepatitis C virus (HCV) infection.If MAFLD is combined with CHC, CHC can lead to insulin resistance, increase the oxidative stress of hepatocytes, accelerate the steatosis of hepatocytes, and affect the therapeutic effect of MAFLD.

Problem—based Learning(PBL) fit well with characteristic of military foreign medical students and the peculiarity of preventive medicine.In order to improve the self-studying and problem-solving ability of foreign students,attention should be paid to several key points to PBL,such as teaching content selection,informationization teaching tool application and teacher cultivation etc.

Recent studies show that cholecystokinin, a brain-gut peptide, also locates in lung tissues in many animals. Cholecystokinin in lung tissues participates in the modulation of the tone of the tracheae and the pulmonary vessels. It also regulates the breathing pattern as a nerve transmitter in the respiratory center. This paper discusses the location and the biological role of cholecystokinin in lung tissues and focuses on its part during lung diseases.

OBJECTIVE: To investigate the use of psychotropic substances for outpatients in our hospital.METHODS: The psychiatric substances used in the outpatients between June and December in 2006 were analyzed statistically in respect of the defined daily dose,DDDs and average daily expense etc.RESULTS: Of the total 7 286 prescriptions analyzed,the psychotropic substances prescribed totaled 12 kinds,of which,2 were typeⅠ,and 10 type Ⅱ.Estazolam,Alprazolam and Diazepam ranked at the first three places in terms of numbers of prescriptions;Estazolam,Alprazolam and Clonazepam ranked at the first three places in terms of DDDs;Zolpidem,Midazolam and Alprazolam ranked at the first three places in terms of consumption sum;Nitrazepam,Estazolam and Phenobarbital ranked at the lowest places in terms of average daily expense.CONCLUSION: Of the total psychiatric substances consumed in the outpatients of our hospital,benzodiazepines were used predominantly for their merits of low cost but proved efficacy.

Objective: To observe the changes of free amino acids (FAAs) in plasma and brain of rats during simulated sea sickness and post–adaptation. Method: Pica or kaolin consumption was used as an indicator to judge the development of sea sickness and adaptation when SD rats were stimulated by Crampton sea sickness simulator. FAAs concentrations in plasma and brain of rats were determined by high performance liquid chromatography (HPLC) after simulated sea sickness and post-adaptation. Results: After simulated sea sickness stimulation for 1 d, the levels of Cys and Ile were increased, and Gly and Pro decreased significantly in plasma. The increase of BCAA/AAA ratio was also found. In brain, the contents of Ala, Cys+Met, Tyr, His, and total amino acids were remarkably decreased. After simulated sea sickness stimulation for 21 d, no changes of FAAs were observed in plasma and brain but the ratio of Glu/ GABA was increased in brain. There were no differences of FAAs, Glu/GABA ratio and BCAA/AAA ratio in plasma and brain of tolerant and susceptible sea sickness rats. Conclusion: The levels of amino acids, especially those related to neurotransmitter synthesis, in plasma and brain were changed significantly during sea sickness.

Objective To investigate changes of oxidative stress in the hearts and their roles in diabetic cardiomyopathy of rats.Methods Thirty six rats with diabetic cardiomyopathy were induced by streptozocin(STZ),and were randomly divided into three groups:(1) normal control (NC) group,normal control rats; (2) Diabetes maintain (DM) group,diabetic rats received protamine zinc insulin (PZI) 2 ～4 U/2 days; and (3) Diabetes treatment (DT) group,diabetic rats received PZI 9 ～ 12 U/kg body weigh/day.After 12 weeks,rats were killed,and the parameters including blood glucose,glycated hemoglobin a1c (HbA1c),total cholesterol (TC),and triglyceride (TG) were measured.Maleic dialdehyde (MDA),the total antioxidant capacity of the hearts,and activities of antioxidant enzymes in hearts including total superoxide dismutase (TSOD),catalase (CAT),and glutathione peroxidase (GSH-Px) were measured by chromatometry.The pathologic changes of heart tissues were studied by hematoxylin eosin (HE),periodic acid Schiff (PAS),and nitrotyrosine (NT) staining.Results After 12 weeks,parameters including blood glucose,HbA1c,TC,and TG were increased significantly in DM group relative to NC group or DT group.The level of heart MDA was elevated obviously in the DM group [NC group (7.82 ±0.62) nmol/mgprot,DM group (12.81 ± 1.35) nmol/mgprot,and DT group (8.20 ±0.85) nmol/mgprot].The total antioxidant capacity and activities of TSOD [(235.09 ± 14.94) U/mgprot],GSH-Px [(56.59 ± 4.96) U] were decreased significantly in the DM group.The level of CAT [(13.84 ± 2.88) U/mgprot] was increased obviously in the DM group.The cardial myocyte hypertrophy,myocyte steatosis,and PAS positive material could be found in the hearts of rats in DM group with HE and PAS staining.The expression of NT was much stronger in DM group than NC or DT groups.NT was less expressed in DT group,and was almost not expressed in the NC group.Conclusions Oxidative stress could be caused by diabetes in diaetic hearts and might play an important role in the etiology of diabetic cardiomyopathy.

AIM: To elucidate the anti-inflammatory mechanism of cholecystokinin octapeptide (CCK-8). METHODS: The pulmonary interstitial macrophages (PIMs) from rats were stimulated with LPS (1 mg?L~(-1)) in the presence or absence of CCK-8 (10~(-8)-10~(-6) mol?L~(-1)) or/and CCK receptor antagonist proglumide (2 mg?L~(-1)). The expression of TNF-? mRNA was assayed by reverse transcription polymerase chain reaction (RT-PCR) at 3 h of the stimulation, and nuclear factor-?B (NF-?B) binding activity was analyzed by electrophoretic mobility shift assay (EMSA) at 1 h of stimulation. The I?B? protein level in the cytoplasma at 30 min of the stimulation was detected by Western blot. RESULTS: CCK-8, at concentrations from 10~(-8) mol?L~(-1) to 10~(-6) mol?L~(-1) obviously inhibited LPS-induced TNF-? mRNA expression and NF-?B binding activity in a dose-dependent manner. Stimulation with LPS resulted in a reduction of I?B? protein level in PIMs, which was elevated by CCK-8. The effects of CCK-8 on NF-?B activity and I?B protein level were attenuated by CCK receptor antagonist proglumide. CONCLUSION: CCK-8 inhibits LPS-induced TNF-? mRNA expression by regulating NF-?B activity in rat PIMs, which is mediated through CCK receptors and inhibition of I?B? degradation. This represents one of the anti-inflammatory mechanisms of CCK-8.
