Objective To explore the causes of misdiagnose of ectopic pregnancy by retrospective analysis in our hospital cases,in order to increase the diagnose and curative level in ectopic pregnancy.Methods Clinical data of the misdiagnosis of 96 cases from the 357 patients of ectopic pregnancy in our hospital from year 1993 to 2002,including materials of histories ,symptoms signs and laboratory examinations were retrospectively analyzed.Results The misdiagnosis rate of ectopic pregnancy in our hospital was 26 9%, most of them were treated as early pregnancies, threatened abortions etc. The causes of misdiagnosis were neglectful of asking essential history, no overall physical examination and misleading by the laboratory results.Conclusions The effectively preventive measures against misdiagnosing of ectopic pregnancy were strengthen vigilance of ectopic pregnancy,familiar with the knowledge of atypical ectopic pregnancy and the essential examinations on gravida.

Objective To determine whether the anti-proliferation effect of L-arginine is due to inhibiting the expression of cyclin dependent kinase-2 (CDK2)、 CyclinE and proliferation cell nuclear antigen (PCNA) in blood vessel after balloon injury. Methods Rats were randomized into three groups: Group S (sham operation group), Group C (balloon injury control group) and Group L (balloon injury + L-arginine group). After 14 days, blood samples were collected for biochemical studies, and the thoracic aortas were harvested for immunohistochemistry. The expression of CDK2、 CyclinE and PCNA were measured by means of computer image analayzer. Results The levels of plasma nitric oxide (NO) in group C were significantly lower than those in group S. Compared with group C, the levels of plasma NO increased (P

Objective To Study the effect of splenectomy plus endoscopic varices ligation (SEVL) in the treatment of portal hypertension. Methods SEVL was carried out in 38 patients with portal hypertension from January 2000 to June 2002. The authors compared hemodynamic parameters and gastric emptying time before and after the operation. The incidence of upper gastrointestinal bleeding, the disappearance rate of esophageal varicosis, the outcomes of portal hypertensive gastropathy (PHG) and the incidence of complications were recorded at postoperative 3 weeks, 6 months, 12 and 18 months, respectively. Results Postoperatively, the free portal pressure, portal flow volume and velocity were significantly reduced in all the cases ( P 0.05). Portal thrombosis was seen in 6 cases (6/38, 15.8%). Conclusions SEVL has little influence on gastric emptying and PHG, offering a high disappearance rate of varicosis and a low incidence of complications.

Objective To evaluate the effect of endoscopic variceal ligation(EVL) combined with splenectomy for the patients with portal hypertension. Methods Thirty two cases of portal hypertension underwent EVL plus splenectomy from May 1999 to May 2002 in our department. The patients were registered and followed up in the third, sixth and twelfth months after operation respectively. Re ligations were performed in case of relapsed varices. Results Thirty one patients were followed up for ≥2 years.Of them,esophageal varices recrrented in 6.4% of patients during following-up period,but no reblecding, and no death caused by hepatic encehpalopathy or other complications.Conclusions EVL combined with splenectomy has less trauma , less postoperative complications and high eradication rate of esophageal varices, so it can be used safely in the treatment of patients with ruptured esophageal varices.

Objective To investigate the influence of pravastatin on serum matrix metalloproteinases-1(MMP-1), MMP-9 and its role in prevention of restenosis following coronary intervention. Methods Totally 62 patients after percutaneous coronary intervention (PCI) were randomly assigned to receive 10 mg/d pravastatin in 24-48 h after PCI for 6 months (n=32) or no therapy (n=30) as control. The blood samples of all patients were examined at admission and 7, 21 d after administration of pravastatin. All patients received follow-up and coronary checking within 6 months. Results TIMI 3 flow was achieved in all cases and residual stenosis was less than 20%. No severe complications were found. ①The use of pravastatin after PCI could significantly reduce serum levels of MMP-1 and MMP-9 as compared with control group (P

Objective To investigate sexual life associated with hysterectomy of young women and its related factors.Methods Data from 199 patients with hysterectomy were collected.Statistical analysis was performed between the postoperative recovery condition among them,including daily life and sex life.Results There was significant difference on sexual life quality of the patients by hysterectomy among patient age,occupation,education,postoperative time,disease and complication (P ＜ 0.05).The age of 41-50 years and 51-60 years old patients' quality of life satisfaction was significantly higher than that of age ≤40 years old patients (OR =3.8,95 ％ CI 1.36-10.66; OR =3.6,95 ％ CI 1.24-10.43).The patients of the occupation of service sectors,workers,and patients with free occupation have a decreased satisfactions compared with that of farmer patients (OR =0.46,95 ％ CI 0.12-1.75; OR =0.75,95 ％ CI 0.27-2.12; OR =0.94 95 ％ CI 0.45-1.98).There was a increasing satisfactions in administrative and the intellectuals (OR =1.11,95 ％ CI 0.34-3.62; OR =1.33,95 ％ CI 0.35-5.10).Patients with primary school educations as a reference for comparison,the quality of life of patients with associated college and above degree were increased than patients with primary school (OR =1.15,95 ％ CI 0.43-3.04),and were decreased in the patients of the high and middle school (OR =0.98,95 ％ CI 0.46-2.11; OR =0.63,95 ％ CI 0.26-1.54; OR =0.15,95 ％ CI 0.02-1.27).The quality of life satisfaction of long period patients (7-12 months,13-24 months,24 months after the operation)was significantly higher than that of short period patients with 6 months(OR =1.94,95 ％ CI 0.65-5.83; OR =6.32,95 ％ CI 2.17-18.38; OR =8.47,95 ％ CI 2.92-24.56,P ＜ 0.001).Conclusion The doctors need focus on relative knowledge education of perioperation.It is important to inform patients and their spouses to have the knowledge of female physiology,fully understanding the impact of the extent of surgery on sexual life of patients to enhance the confidence and improve the life quality of patients.

AIM: To investigate the protective effect and mechanisms of di-ao-xin-xue-kang (DK) on myocardial ischemia-reperfusion. METHODS: Models of myocardial ischemia-reperfusion were constructed with sixteen mongrel dogs. The left ventricular pressure (LVSP), the marximal/minimum rate of LVSP (?dp/dt max) and the serum aspartate aminotransferase (AST), creatine kinase (CK), lactate dehydrogenase (LDH), malondialdehyde (MDA) were determined before and 90 minutes after occlusion, 120 and 240 minutes after reperfusion, and the MDA content in myocardial cell membrane prepared at 240 minutes after reperfusion was determined. The oxygen free radical was assayed with electron spin resonace spectroscopy (ESR) technique. RESULTS: ① LVSP and ?dp/dt max in the normal saline control (NS) group decreased with the time progress of occlusion-reperfusion, and it was the same in DK group, but the levels were significantly higher than that in NS group (P

Objective To evaluate the effect and safety of combined treatment by laparoscopic cholecystectomy and subsequent ablation in patients with HCC adjacent to the gallbladder. Methods From June 2005 to June 2009,13 patients with HCC nodules( less than 3 cm) adjacent to the gallbladder were treated by ablation after laparoscopic cholecystectomy. The rate of complete necrosis as well as postoperative complications were also analyzed. Results All the patients showed complete necrosis of their tumor lesions after treatment by ablation subsequence of laparoscopic cholecystectomy. During the follow-up period( nearly 2 years), recurrent nodules appeared in other subsegments but not at the original site treated by ablation. Of note, no fatal complications were observed in all the ablation treated patients. Conclusion Combined treatment by laparoscopic cholecystectomy and subsequent PMCT was an effective and safe method for patients with small HCC which was adjacent to gallhladder.

Objective:To analyze the invasion characteristics and prognostic factors of patients with Masaoka-Koga stage Ⅲ thymoma.Methods:The tumor invasion characteristics of 179 patients who were diagnosed with Masaoka-Koga stage Ⅲ thymoma and treated in Affiliated Cancer Hospital of Zhengzhou University from January 2000 to June 2018 were analyzed retrospectively. According to the treatment methods, all patients were divided into the radical operation group ( n=94), palliative operation group ( n=39) and simple biopsy group ( n=46). The χ2 test was used to compare the classified variables, Kaplan- Meier method was utilized to calculate the cumulative survival rate, log-rank method was used for group comparison and univariate analysis, and Cox’s regression model was used for multivariate analysis. Results:Mediastinal pleural invasion (86.0%) was the most common site, followed by pericardium (50.8%), great vessel (40.8%) and lung (36.3%). The proportion of macrovascular invasion in the radical operation group was 14.9%, significantly lower than 79.5% and 60.9% in the palliative surgery group and biopsy group (both P<0.001). Multivariate analysis showed that the nature of operation ( P<0.001), age ( P=0.011), radiotherapy ( P=0.020) were the independent factors affecting overall survival (OS), while nature of operation ( P<0.001), age ( P=0.004), radiotherapy ( P=0.020), number of invasive organs ( P=0.023) and pathological type ( P=0.016) were the independent factors affecting progress-free survival (PFS). Conclusions:For patients with Masaoka-Koga stage Ⅲ thymoma, mediastinal pleura is the most common site of invasion, pericardium, lung and great vessels are also commonly invaded. The invasion of mediastinal pleura, pericardium and lung exerts slight effect on surgical resectability, whereas great vessel involvement can significantly affect surgical resectability. OS and PFS in patients undergoing radical resection are significantly better than those in patients treated with palliative resection and biopsy. Radical resection is the most important factor affecting prognosis.
