[Objective] To sum up the clinical experience of famous veteran doctor LI Rongzhen in treating the fundus oculi disease. [Methods] By learning from Professor LI Rongzhen, recording the relevant cases and analyzing the typical cases, to summarize the academic idea and the clinical experience according to the viscera syndrome differentiation and treatment characteristics, as well as list two proved cases. [Results] Professor LI Rongzhen holds that this disease is closely related with the viscera, origins from heart, involving liver, lung and kidney. In the clinical treatment, Professor LI is good at using the classical prescriptions and the therapy with syndrome differentiation with the permit addition and subtraction, according to the pattern of the fundus oculi disease, which has received the remarkable effect: patients with the deficiency of both heart and spleen of sudden blind, using the principle of nourishing qi to stop bleeding with Guipi Decoction, patients with hyper-action of liver yang, using Zhengan Xifeng Decoction to nourish yin for suppressing hyperactive yang, patients with qi stagnation and blood stasis are treated by Xuefu Zhuyu Decoction to remove stasis and stopp blood;patients with deficiency of kidney-yin of vitreous opacity, using the treatment of tonifying kidney for improving eyesight, with Six Ingredient Rehmannia Pill to nourish the liver and kidney, syndrome with the disharmony of liver and spleen, using Xiaoyao Powder to replenish vital energy ,deficiency of qi and blood, applying Bazhen Decoction to invigorate qi and blood. All of the cases verify her clinical experience. [Conclusion] While treating the fundus oculi disease, Professor LI pays attention to the relation between the eyes and the viscera, using the therapy with syndrome differentiation, with the flexible application of the ancient prescriptions and the traditional Chinese medicine, her experience in treating the fundus oculi disease is well worth learning and using.

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 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 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 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.

Objective To study the signification of p57kip2 immunostaining to distinguish molar gestations from hydropic abortions.Methods To observe the p57kip2 immunohistochemical expression in 58 cases of histological hydropic villi which were divided into complete mole(18 cases) ,partial mole(19 cases),hydropic abortion(11 cases)and undetermined hydropic abortion or molar gestations(10 cases) and in 3 normal placentas.Results Normal villi,partial mole and hydropic abortions show positive staining for p57kip2, which expressed in the nuclei of cytotrophoblast and villous mesenchyme,and complete moles show complete absence of staining in the cytotrophoblast and villous mesenchyme.According to the comparison of the diagnosis based on morphology and the one based on p57kip2 stai-ning,the later whose sensitivity is 96% (46/48) confirmed the earlier diagnosis in 58 cases studied and the later conformed to the earlier very well.Conclusion The immunohistochemical staining for p57kip2 is a valuable diagnostic mean to distinguish molar gestations from hydropic abortions and is a sensitive and specific marker for the diagnosis of complete mole.
