Journal of Peking University(Health Sciences) 2004;0(03):-
Objective: To investigate the possible association between the allelic variation of LAPTM4B and the genetic susceptibility of lung cancer. Methods: The genotype of LAPTM4B was analyzed in 134 unrelated healthy adult individuals and 166 patients with lung cancer by utilizing polymerase chain reaction based on special primers. The genotypical distribution of LAPTM4B was analyzed by ? 2 test. Results: The allelic frequencies of the *2 were 40.1% and 28.0% in the lung cancer group and the healthy control group respectively, which was significantly different between the two groups (P 0.002). There was a significant difference in the overall genotypical distribution between the patients and the controls (P0.005). The risk of suffering from lung cancer was increased 1.91 times in the individuals of the *1/2 genotype (95%CI: 1.178-3.110) and 3.26 times in the individuals of the *2/2 genotype of LAPTM4B (95%CI:1.338-7.929) compared with the *1/2 genotype. No association was observed between the genotypical distribution of LAPTM4B and the clinical information on patients of lung cancer such as gender, age, pathological type, differentiation classification of TNM and infection of HBV. Conclusion: This study suggests that the allele *2 of LAPTM4B might be the risk factor of lung cancer, which could be associated with genetic susceptibility of lung cancer.

BACKGROUND: Diabetic cardiomyopathy is closely related to the high incident rate of diabetic heart failure. It is extremely significant to set up the successful dietetic cardiomyopathy model for the study on improving cardiac function.OBJECTIVE: To understand the influence of high blood sugar on myocardium by setting up the model of type 2 diabetes and diabetic cardiomyopathy.DESIGN: Completely randomized design, randomized and controlled study,in which, the experimental animals were taken as the objects.SETTING: Department of endocrinology of a university.METHODS: In the experiment, 99 newly born Wistar male rats were employed, randomized into experiment group (75 rats) and the control group(24 rats). In the control group, abdominal injection was done with sodium citrate buffer and the single abdominal injection was done with strptozocin(STZ)90 mg/kg in the experiment group. Ten weeks later, the glucose tolerance was assayed to determine the set-up of diabetes model. The ultrastructure of myocardium of rats was tested under electronic microscope after being sacrificed.MAIN OUTCOME MEASURES: To observer whether the myofibrillae and mitochondria of myocardiocytes alter or not in diabetic rats.RESULTS: In the experiment group, the fasting blood sugar[(8.87± 0.76)mmol/L] was slightly higher than that[ (5.88 ± 0. 45)mmol/L] in the control group, the blood sugar 2 hours after meal was remarkably higher than that in the control group and the glucose tolerance was abnormal. Under the electronic microscope, the myofibrillae presented focal degeneration and disarranged order of myofilament; mitochondria of myocardiocytes presented swelling and focal proliferation.CONCLUSION: This model is the satisfactory carrier for the study on diabetes Ⅱ and its myocardiopathy, which lays an experimental foundation for the study on cardiac function of type 2 diabetes.

By combing differe nt modelin g factors and evaluation indicators of experimental animals of polycystic o-vary syndrome (PCOS), application scope, advantages and disadvantages were analyzed among various kinds of animal models, in order to screen models of etiology and pathogenesis in traditional Chinese medicine (TCM). Through the collection of 77 Chinese literatures published since 1979, the database on PCOS of modeling factors (i.e., animal species, age, modeling reagent and dose, etc.) and evaluation indicators (i.e., ovarian morphology and hormone levels) were established, analyzed and summarized. The results showed that the experimental PCOS models established by researchers both at home and abroad included androgen method, combination method of androgen with HCG, combi-nation method of progestrone with HCG, estrogen method, aromatic cyclase inhibitor method, combination method of HCG with insulin, combination method of androgen with insulin, insulin method, and etc. The SD and Wistar rats at the age of 3-50 days were commonly used. Chemicals, such as dehydroepiandrosterone (DHEA), testosterone propi-onate, sodium prasterone sulfate, dihydrotestosterone (DHT), levonorgestrel, estradiol valerate, letrozole, insulin and HCG were chosen to build the animal models. The evaluation indicators included ovarian morphology, the total num-ber of follicles at different levels, sex hormones (E2, P, T, FSH, LH) and insulin resistance (IR) index (FINS, FPG, HOMA). It was concluded that each modeling method described above had its own advantages and disadvantages, which cannot completely simulate clinical onset process of PCOS patients. Researchers should choose appropriate reagent and evaluation index according to different purpose. DHEA, DHT slow-release, progesterone combined with HCG modeling methods are more suitable for the study of the role of IR in the pathogenesis of PCOS. Kidney-defi-ciency and dampness-phlegm is fundamental etiology and pathogenesis of obese type of PCOS. DHEA method, com-bination method of levonorgestrel with HCG, aromatic cyclase inhibitor method conformed obese type of PCOS. The evaluation indicators included body weight, sex hormones, IR index and ovarian morphology. The method of kidney-tonifying and phlegm-reducing was often used in the treatment of obese type of PCOS in the clinical practice.
