Objective To evaluate the efficacy of laparoscopic operations in the treatment of ectopic pregnancy.Methods A total of 148 cases of tubal pregnancy from January 2002 to January 2005 were studied.Laparoscopic operations included 106 cases of oviduct-sparing operation(79 cases of oviduct fenestration and 27 cases of lesion clearance),37 cases of salpingectomy,and 5 cases of lesion clearance.Results The diagnosis and operation were laparoscopically completed in all the 148 cases.Persistent ectopic pregnancy occurred in 2 cases.Postoperative monitoring of serum ?-hCG levels showed the shortest recovery time to normal levels after the treatment of salpingectomy(8?1 d),and the longest one after lesion clearance (15?2 d).Regular menstruation resumed at((31?)2 d) after salpingectomy and at(43?3 d) after lesion clearance.Follow-up checkups with uterotubography in 84 cases for 1~3 months(mean,2.3 months) found a patent rate of both oviducts of 82.1%(69/84).Conclusions Laparoscopic operations is a safe and effective option in the treatment of ectopic pregnancy.

Xanthine-Xanthine oxidase ( X-XOD) added to the culture medium of cultured cardiac cells in rats may damage cell membrane. Electrophysiological findings indicated that APA, MDP, OS,Vmax, were decreased and the SDF was increased. Astragalus polysaccharide (APS) could protect the cells from being damaged by X-XOD. APS recoverted all the de-creased cardiac functional parameters in free-radical-damaged rats by X-XOD. APS had anti-free-radical damage action on the cultured my-ocardiocytes and the myocardial contractility of the isolated rat working heart.

Objective To explore the relation between clinical-pathological features,Siewert classification and prognosis of esophagogastric junction (EGJ) carcinoma,and to assess the applicability of the new edition of American Joint Committee of Cancer (AJCC) staging guideline on EGJ adenocarcinoma in China.Methods From 2002 to 2012,the clinical data,pathological features,treatment and prognosis of 218 patients with EGJ malignant tumor were retrospectively analyzed.The patients were typed according to Siewert classification criteria and each case was staged according to 7th edition of AJCC TNM staging criteria for esophagus adenocarcinoma and gastric cancer.Kaplan-Meier method and Log-rank test were performed for survival analysis.Results According to the Siewert classification,type Ⅰ was rare (nine cases,4.1％),type Ⅱ was the most common type (150 cases,68.8％) and followed by type Ⅲ (59 cases,27.1％).There was no significant difference in survival curve among the three types (P＞0.05).The survival curve was drawn according to 7th edition of AJCC TNM staging criteria for esophagus adenocarcinoma.In T staging,the prognosis of patients at T4b was better than that of patients at T4a,the prognosis of patients at ⅡB was better than that of patients at ⅡA.The survival curve of patients at Ⅲ C obviously crossed with that of patients at Ⅳ,which was not in conformity with clinical results.The survival curve was drawn according to 7th edition of AJCC staging criteria for gastric cancer.In T staging,the survival curve of patients at Tis was overlapped with that of patients at T1a.The survival rate of patients at ⅡB could not be accurately predicted by the overall staging.In general,the survival of patients with EGJ carcinoma was better predicted according to 7th edition of AJCC staging criteria for gastric cancer than 7th edition for esophagus adenocarcinoma.Conclusions Neither 7th edition of AJCC staging criteria for esophagus adenocarcinoma nor for gastric cancer could accurately predict its prognosis.In our country,EGJ malignant tumor was similar to gastric cancer and had specific clinical-pathological features.It is necessary to research and establish EGJ carcinoma staging criteria instead of applying the current staging criteria for esophagus adenocarcinoma or gastric cancer.

Objective To explore the histopathological features of 850 patients with esophageal malignant tumor in 10 years.Methods From January 2002 to January 2012, 850 patients diagnosed with esophageal malignant tumor were enrolled.Tumor location, general type, pathological type and TNM stage were retrospectively analyzed.All the data were described as case number and percentage.Results Among the 850 cases of esophageal malignant tumor, 33 lesions (3.9％) located in the neck segment of esophagus, 119 lesions (14.0％) located in the upper segment, 44 lesions (5.2 ％) located in the upper-middle segment, 409 lesions (48.1％) located in the middle segment, 123 lesions (14.5 ％) located in the middle-lower segment, 122 lesions (14.4％) located in the lower segment.Among the 724 eases clearly diagnosed as esophageal malignant tumor by general type, the most cases were ulcer type (305 cases, 42.1％), followed by medulla type (260 cases, 35.9％), fungating type (80 cases, 11.0％) and constrictive type (70 cases, 9.7％), and the least cases were intraluminal type (nine cases, 1.2％).Among the 850 cases of esophageal malignant tumor, squamous cell carcinoma (794 cases, 93.4 ％) was the most common cytological type, followed by small cell carcinoma (19 eases, 2.2％), and the least common cytological type was adenocarcinoma (seven cases, 0.8 ％).Among the 724 cases with clear TNM staging, case number of Tis, T1, T2, T3 and T4 stage was eight (1.1％), six (0.8％), 271 (37.4％), 278 (38.4％) and 161 (22.2％), respectively.Among the 122 cases of distal esophageal carcinomas (104 cases with clear TNM staging), most cases were squamous cell carcinoma (112 cases, 91.8 ％), the others cases were adenocarcinoma (three cases, 2.5 ％), small cell carcinoma (three cases, 2.5 ％), basaloid squamous cell, adenosquamous, neuroendocrine carcinomas and carcinosarcoma (one case in each type, 0.8％).Conclusions Esophageal carcinoma was mostly located in the middle segment of in which squamous cell carcinoma was predominant while adenocarcinoma was less common.Esophageal cancer located at lower segment of esophagus is with a wide range of pathological spectrum, squamous cell carcinoma was still dominant, however, esophageal adenocarcinoma is rare.

The supramolecular inclusion properties of beta-cyclodextrin (beta-CD) and resveratrol (Res) were investigated using drug-protein interaction spectroscopy method. The differences between the results of interaction spectroscopy method and the results of classical method were compared. The total energy of the stable inclusion of cyclodextrin-resveratrol was calculated by Gaussian theory calculation. The stable inclusions in the process of interaction between resveratrol/inclusion complex and bovine lactgoferrin (BLF) were studied by molecular modeling. The results showed that the interaction spectroscopy method could explain the property of the inclusion in a more sensitive manner, it also interpreted the conveying mechanism of BLF binding with inclusion complex. The molecular modeling result showed consistent results with Gaussian theory calculation; both of the two methods obtained the stable configuration of beta-CD-Res inclusion. The relevant result provided an experimental consequence for the pharmacology research of beta-cyclodextrin-resveratrol inclusion complex as well as offering a new reference to the future research of supramolecular inclusion compound.
