Recurrent spontaneous abortion (RSA) was one of the most difficult infertile diseases which was usually defined as consecutive still birth for more than three times during the first 20 weeks of gestation. Various factors and pathogeneses were thought to play a role in RSA. Recent studies had indicated that the disorders of blood vessel growth and the secondary abnormal blood perfusion may contribute to the occurrence of RSA. However, blood vessel growth was linked with the regulation of angiogenesis related factors. To provide references for the clinical prevention and treatment, the purpose of this paper was to evaluate the association between solubility vascular endothelial growth factor receptor-1(sflt-1), thrombospondin 1(TSP-1) and ovary, endometrial abnormal blood perfusion in cases of RSA.

Objectives: To investigate the affecting factors on expenditure in Medical insurant inpatients. Methods: 593 medical insurant inpatients, who were from Feb 1, 2001 to Feb 31, 2002 in Nanjing Jinling hospital, were enrolled in this study. The inpatient expenditure was analyzed from the aspect of operation or not, age, and payment mode, used the descriptive analysis and multi factor analysis on affecting factors of the total expense, self bearing expense, and self affording expense. Results: The hospitalized days, operation or not, severity of disease were important affecting factors. The self bearing expense of medical insurant inpatients was associated with hospitalized days, operation or not, and total expense. While the self affording expense of them was associated with expense of drug, hospital bunk, radiation and others. Conclusions: We can control these associated affected factors to lighten the economic weight of patients, and to reduce the ratio of individual payment.

Objective To explore the sexual life quality of females at the reproductive ages after cervix cancer operation and supply evidence for establishment of correspondindg nursing measure. Methods We investigated the frequency of sexual life and satisfaction degree of sexual life in 40 females at the reproductive ages after cervix cancer operation by face-to-face investigations using questionnaires before and 4 months after operations. Then the difference of sexual life quality before and after operation were compared and analyzed. Results The frequency of sexual life (P＜0.01,P＜0.05) and satisfaction degree of sexual life (P＜0.01,P＜0.05) were evidently decreased. The sexual life quality was lower than that before operation. Conclusion The sexual life quality could be affected by many factors such as economic conditions, culture background, sexual conceptions and the attitude of their partners.

Objective To investigate the protective effect of rhein lysinate (RHL)on the liver of the models with diabetic rats,and to provide basis for research on treatment of fatty liver in the patients with diabetes mellitus. Methods The models of diabetic rats were established by intraperitoneally injecting streptozotocin(STZ).40 rats were divided into control,model,25 mg·kg-1 RHL,and 50 mg·kg-1 RHL groups(n=10).The levels of malonaldehyde (MDA)and the activities of superoxide dismutase (SOD)and glutathione peroxidase (GSH-Px) were detected by thiobarbituric acid method, pyrogallol autoxidation method, and NADPH coupling method, respectively.The pathological changes of liver tissue were observed by hematoxylin and eosin (HE)staining;the content of fat in liver tissue was observed by Nile red staining;the expression levels of fat synthesis-related proteins were detected by Western blotting method.Results Compared with control group,the body weight of the rats in model group was decreased and the levels of blood glucose,total cholesterol(TC)and triglyceride(TG)were increased (P<0.05);the activities of SOD and GSH-Px in liver tissue were decreased (P<0.05);there were a plenty of fat vacuoles and fat accumulation in liver tissue. The signal pathway of fat synthesis-related ERK1/2-SREBP-1c was activated in model group;compared with model group,it was inhibited in 25 and 50 mg· kg-1 RHL groups (P<0.05).Compared with model group,the blood glucose,TC and TG of the rats in 25 and 50 mg ·kg-1 RHL groups were decreased (P<0.05);the activities of SOD and GSH-Px were increased (P<0.05);however the body weight had no change. Compared with model group, the fatty vacuoles and the fatty accumulation of liver tissue in 25 and 50 mg·kg-1 RHL groups were decreased. Conclusion The hepatic protection of RHL is correlated with the inhibition of oxidative stress, fat degeneration and fatty accumulation of liver tissues.

Objective: To investigate the antimicrobial resistance in and multilocus sequence typing (MLST) of Campylobacter jejuni in meat and meat products in Liaoning Province, so as to provide insights into the management of C. jejuni infection. Methods: Nine C. jejuni isolates from meat and meat products in 2020 were subjected to whole genome sequencing, and the minimum inhibitory concentration was measured with the agar dilution method. MLST of C. jejuni isolates was performed with the microbial resistance mechanism traceability reference database and analysis system. Results: Six drug-resistant C. jejuni isolates were detected, and there were four multidrug-resistant isolates. There were six C. jejuni isolates resistant to tetracycline, five isolates resistant to nalidixic acid, four isolates resistant to ciprofloxacin, two isolates resistant to florfenicol, one isolate resistant to gentamicin and one isolate resistant to streptomycin. Nine C. jejuni isolates showed sensitive to azithromycin, chloramphenicol and clindamycin. MLST identified six ST types in nine C. jejuni isolates, with ST45 and ST2274 as the predominant type, and detected one isolate with unclassified ST type. Phylogenetic analysis showed that KW028 and KW029 of ST45 type were closely related and had high homology, and KW040 and KW042 of ST2274 type were closely related with high homology, while KW007 of ST6701 type was closely related to KW040 and KW042 of ST2274 type, with only one pgm housekeeper gene in difference. Conclusions High resistance to tetracycline, nalidixic acid and ciprofloxacin was detected in nine C. jejuni isolates from meat and meat products, and ST45 and ST2274 were predominant ST types of C. jejuni.
