Objective To study the efficacy of laparscopic operation in the treatment of repeated ectopic pregnancy. Methods 42 patients with repeated ectopic pregnancy were treated by salpingotomy, salpingectomy and adhesiotomy. Results All cases were managed under laparoscopy successfully, and no complication occurred. 28 cases were followed up for ( 6～50) months after operation, and postoperative pregnancy rate was 25%(7/28). Conclusions Laparoscopic operation can be the first choice of treatment of repeated ectopic pregnancy with minimal invasion and quicker recovery.

Objective To develop a more effective method to treat proximal tubal obstruction. Methods In a total of 89 cases, there were 113 oviduct lesions diagnosed by hysterosalpingogram (HSG) and then by laparoscopy as proximal tubal obstructions. Intubations and recanalizations were performed by means of laparoscopy combined with hysteroscopy. Results Out of the 113 oviduct lesions in 89 cases, 73 (64.6%) were recanalized. In follow-up of 20 days～58 months, there were 20 cases of successful pregnancies and labours, 2 inevitable abortions and 1 ectopic pregnancy, with the rate of pregnancy 25.8% (23 of 89). Conclusions It is an effective approach to treat proximal tubal obstruction by using laparoscopy combined with hysteroscopy. It can also be used to identify the true proximal tubal obstruction from the false one.

BACKGROUND: Impaired glucose tolerance(IGT) is mainly related to genetic factors and environmental factors including excessive calorie intake and obesity. Insulin resistance(IR) plays a major role in the onset of IGT.OBJECTIVE: To investigate the relationship between erythrocyte insulinase activity(EIA) and IR in patients with IGT soas to provide theoretic basis for improving IR in patients with IGT by exercise.DESIGN: Observational and comparative study based on IGT patients as the subjects and adults with normal glucose tolerance as controls.SETTING: Department of endocrinology of a hospital affiliated to a military medical university.SUBJECTS: The study was conducted in the Department of Endocrinology of Nanfang Hospital, First Military Medical University of Chinese PLA, from January 2001 to April 2003. A total of 50 inpatients and outpatients with IGT, 26 males and 24 females aged(52 ± 7) years, were randomly selected. Inclusion criteria: those whose diagnosis met the WHO 1999 for criteria oral glucose tolerance test (OGTT) and whose heart, liver and kidney functions and blood test were within the normal range without taking any antidiabetics. Exclusion criteria: those who had liver and kidney diseases, infection, malignant tumor, coronary heart disease, cerebrovascular disorder and connective tissue disease. The patients with IGT were divided into 2 subgroups according to the presence of abnormal fasting plasma glucose (FPG).Subgroup A consisted of 20 patients (9 males and 11 females) with IGT accompanied with impaired FPG. Subgroup B was composed of 30 IGT patients (17 males and 13 females) with normal FPG. Twenty adults with normal glucose tolerance were set as control group(20 females and 10 males) with the age of(48 ± 12)years.METHODS: EIA was measured with the method of radioenzymatic assay in all subjects. Blood sugar, serum insulin and glycosylated hemoglobin were also measured, and homeostasis model analysis-insulin resistance (HOMA-IR) index was calculated for estimation of insulin sensitivity.MAIN OUTCOME MEASURES: The differences and correlation between EIA and HOMA-IR in IGT patients of each group.RESULTS: EIA, serum fasting insulin and HOMA-IR indexes of the patients with IGT were significantly higher than those of the controls ( P < 0.01 or P < 0.05) . EIA and HOMA-IR of the patients in subgroup A was significantly higher than those in subgroup B ( P < 0. 01 ). Linear regression analysis showed that EIA had significant positive correlation with serum fasting insulin, glycosylated hemoglobin and HOMA-IR indexes( r = 0.51, 0.44,0.49, P <0.01).CONCLUSION: The degradation rate of erythrocyte insulinase in patients with IGT tolerance is significantly higher than that of normal persons, and is closely related to the onset and development of insulin resistance.

Objective To study the effect of Jingyebaidu granules on treating cytomegalovirus ( CMV) infection during mid-pregnancy. Methods The sexually mature guinea pigs with no CMV infection history served as the subjects. Put the male and female ones in the same cages. Then the female ones were randomly divided into three groups during mid-pregnancy. Model control group:15 guinea pigs which were inoculated 1 mL suspension of GPCMV intraperitoneally. Jingyebaidu Medicine group:15 guinea pigs which were treated with Jingyebaidu(3. 09 mL·kg-1 ) through stomach perfusion after inoculation for 14 days. Normal control group:15 normal mid-pregnant guinea pigs. Viremia rates were examined 7 days after infection. All animals were sacrificed 20 days after infection. The placenta infection rate, pup infection rate, still-born rate were examined. Results Compared with the normal controls, the still-born rate was increased in model control group(8. 33% vs 34. 55%, P<0. 05). In comparison to the model control group, the GPCMV maternal infection rate(86. 67% vs 33. 33%), placenta infection rate (91. 67% vs 61. 22%), pup infection rate(90. 91% vs 48. 28%), still-born rate(34. 55% vs 15. 52%) were significantly decreased in the Jinyebaidu group (all P<0. 05). Conclusion Jinyebaidu granules could reduce maternal infection,pup loss, and placenta infection caused by CMV inoculation during mid-pregnancy.

Objective To investigate the effects of physical exercises on cardiac function and plasma N-terminal pro-brain natriuretic peptide (NT-proBNP) levels in hypertensive patients combined with diastolic cardiac dysfunction.MethodsA total of 66 essential hypertension patients who had abnormal left ventricular relaxation and normal systolic function were assigned to the intervention group ( n =33 ; doing physical exercises once a day,5 days a week) or control group (n =33 ).All the patients received standard treatment.At 6 months,body weight,blood pressure,heart rate,NT-proBNP,and echocardiography were measured.ResultsAt 6 months,body weight [ (68 ± 7 ) kg vs (72 ± 8 ) kg ],systolic blood pressure [ (135.4 ±5.1) mm Hg (1 mm Hg =0.133 kPa) vs (141.9 ±5.2) mm Hg ],diastolic blood pressure [ (81.1 ±4.0) mm Hg vs (84.7 ±4.6) mm Hg],New York Heart Association class (1.4 ±0.3 vs 1.8 ±0.4),NT-proBNP level [ (526 ± 126 ) ng/L vs (741 ± 189 ) ng/L] were significantly decreased in the intervention group when compared with the control group ( all P ＜ 0.05 ) although left ventricular ejection fraction (LVEF) (62.9 ±6.7 vs 59.0 ±5.6) and E/A ratio ( 1.1 ±0.3 vs 0.9 ±0.3) were significantly increased ( both P ＜ 0.05).ConclusionPhysical exercises could play a role in reduced blood pressure and body weight and improved cardiac function in hypertensive patients with diastolic cardiac dysfunction.

As a common emotional and psychogenic disorder, anxiety disorder seriously threats the human physical and mental health. Ventral tegmental area (VTA) is the canter of the mesocortical limbic circuit, with extensive bidirectional connections to forebrain areas, and plays important role in regulating reward, motivation, cognition, and disgust. Besides, VTA is involved in anxiety regulation by forming functional connections with multiple brain regions and connecting external stimulus information and feedback output behaviours. This article briefly summarizes the different cell subsets of VTA and its involvement in anxiety-related neural circuits.

Objective:To analyze the risk factors of lower extremities deep vein thrombosis after thoracoscopic surgery in elderly patients with lung cancer, establish a nomogram prediction model and conduct internal verification.Methods:A total of 183 elderly patients with lung cancer who underwent thoracoscopic radical resection in Nanchong Central Hospital from February 2018 to February 2022 were selected as the study subjects. According to the presence or absence of deep venous thrombosis of the lower extremities within one month after operation, the patients were divided into lower extremities deep venous thrombosis group ( n=61) and non-deep lower extremities venous thrombosis group ( n=122) . Univariate and multivariate analyses of deep venous thrombosis of lower extremities after thoracoscopic surgery for lung cancer in the elderly were performed, and a nomogram prediction model was constructed according to the multivariate analysis results, and the model was verified. Results:There were statistically significant differences in smoking history ( χ2=13.40, P<0.001) , preoperative chemotherapy ( χ2=8.79, P=0.003) , surgical method ( χ2=7.97, P=0.005) , operation time ( t=7.23, P<0.001) , postoperative bed rest time ( t=10.40, P<0.001) , combined with diabetes ( χ2=6.37, P=0.012) , combined with hyperlipidemia ( χ2=9.58, P=0.002) , preoperative D-dimer ( t=13.08, P<0.001) , preoperative fibrinogen ( t=5.84, P<0.001) and preoperative platelet count ( t=7.01, P<0.001) between the lower extremity deep venous thrombosis group and the non-lower extremity deep venous thrombosis group. The results of multivariate logistic regression analysis showed that preoperative chemotherapy ( OR=2.45, 95% CI: 1.05-5.71, P=0.038) , surgical method ( OR=2.55, 95% CI: 1.14-5.73, P=0.023) , postoperative bed rest time ( OR=1.50, 95% CI: 1.24-1.81, P<0.001) , combined with diabetes ( OR=3.60, 95% CI: 1.05-12.33, P=0.042) , and preoperative D-dimer ( OR=1.01, 95% CI: 1.01-1.01, P<0.001) were all independent risk factors for lower extremity deep vein thrombosis in elderly patients with lung cancer after thoracoscopic surgery. The C-index of nomogram for predicting lower extremity deep vein thrombosis-related factors was 0.86 (95% CI: 0.81-0.93) . The calibration curve showed that the model had a good correlation in predicting lower extremities deep venous thrombosis. Conclusion:Preoperative chemotherapy, surgical method, postoperative bed rest time, combined with diabetes, and postoperative D-dimer level are influence factors for lower extremity deep vein thrombosis in elderly patients with lung cancer after thoracoscopic surgery. The nomogram prediction model established in this study has high accuracy and discrimination for the prediction of lower extremity deep vein thrombosis in elderly patients with lung cancer after thoracoscopic surgery.
