Objective To explore the clinical value of the Luo’s fornix cup in laparoscopic total hysterectomy. Methods A total of 7 patients with indications for hysterectomy from October 2004 to February 2005 was given laparoscopic total hysterectomy. During the operation, the Luo’s fornix cup was used for the orientation and dilatation of the vaginal fornix. Then the anterior vaginal fornix was circlewise incised by using a harmonic hook to extract the Luo’s fornix cup. Afterwards the posterior fornix was opened to remove the uterus by way of the vagina. And finally the vaginal stump was closed. Results All the operations were successfully completed. The operation time was 90~250 min. With the use of the Luo’s fornix cup, the operator could easily identify the top of the vaginal fornix, and avoid the damage of important neighbouring organs. No injuries of bladder, ureter, and rectum were noted. Conclusions The Luo’s fornix cup is a rational accessory instrument in laparoscopic hysterectomy, being worthy of recommendation.

Objective:To investigate the differences between patients with small cell carcinoma of the cervix and other type of cervical cancer on clinicopathological characteristics,treatment,prognosis through the retrospective analysis,also study the prognostic factors in patients with SCCC.Methods:The patients with SCCC(63 cases,research group) and patients with Non-SCCC(60 cases,control group) such as squamous cell carcinoma and adenocarcinoma of cervix were chosen during May 2003 and June 2015 in department of obstetrics and gynecology,west China second university hospital.The clinical pathological and survival data were collected,sort out,checked and analyzed.Chi-square test or Fisher's exact probability method was used to compare the differences of clinical features between the two groups.The 5-year disease-free survival(DFS) rate and 5-year overall survival(OS) rate were generated using the Kaplan-Meier method.Univariate and multivariate analysis were applied to research the prognostic factors.Results:①The median age of the patients in research group was 40 years old,younger than control group whose median age was 44 years old (P =0.001).The rate of lymph node metastasis,parametrial infiltration,vascular involvement and positive surgical margins in research group were significantly higher than those of control group (P ＜ 0.05).There were no significantly differences between two groups in clinical symptoms,FIGO stage,therapeutic schedule.②In the survival analysis,the research group estimated 5-year overall survival (OS) rate (29.2％) and estimated 5-year disease-free survival rate (DFS)(26.6％) was significantly lower than those of the control group(82.6％,and 76.7％,respectively) P ＜ 0.05.③In the COX multivariate regression analysis,the results showed that the lymph node metastasis was the independent factor influencing overall survival rate and disease-free survival rate(HR =4.784、3.067,P ＜ 0.05).In addition,the tumor size was the independent factor influencing overall survival rate (HR =3.610,P ＜ 0.05),and advanced FIGO staging was the independent factor influencing disease-free survival rate (HR =2.793,P ＜ 0.05).Conclusions:The patients with SCCC were younger than other cervical cancer,and the clinical symptoms,cervical appearance,treatment between the two types are almost the same.However,The rate of lymph node metastasis,parametrial infiltration,vascular involvement and positive surgical margins in patients with SCCC were significantly higher than other cervical cancer,and the prognosis of the patients with SCCC was very poor.The main prognostic factors were lymph node metastasis,advanced FIGO stage and tumor size.

Background and purpose: E-cadherin (EC) is a type of glycoprotein, which could maintain epithelial polarity and cell-cell junction. It is thought to be associated with the development and progression of hepatocellular carcinoma (HCC). The study aimed to detect expression of uniting detection sEC and AFP before and after operation in patients, and to monitor recurrence of postoperative. Methods:The levels of sEC and AFP in 105 HCC patients were tested by enzyme linked immunosorbent assay (ELISA) and radioimmunoassay (RIA) before and after operation as well as in 70 healthy controls. Theirs correlation with clinical and pathological factors was analyzed. We analyzed the level of plasma sEC and AFP of 47 patients who had been suffered from the hepatocellular carcinoma operation and relapse. Results: The levels of sEC and AFP in HCC patients before operation were significantly higher than in controls, which declined significantly one week after operation. The sEC level before operation showed significant correlation with TNM staging (P<0.01), edmondson grade, the carcerous thrombi within the portal vein and the capsule of carcinoma (P<0.05), but not with age of patients or the tumor size (P>0.05). While AFP only correlation with TNM staging (P<0.05), not with others factors (P>0.05). When the recurrence was confirmed, the level of sEC was much higher significantly than the level postoperation (P<0.01). Conclusion:The levels of sEC in HCC patients before operation are closely related with prognosis and recurrence of HCC. The unites detection of sEC+AFP may be a predictive factor for recurrence of postoperation.

Objective To investigate the changes of airway resistance before and after Bronchial Diulation Test in patients with senile asthma and the effect of age on the degree of airway resistance. Methods A total of 29 (> 60 years)senile asthma patients and 21 younger(< 60 y)patients were enrolled in the study. The status of their pulmonary function was determined by MEFV(Maximum expiratory flow?volume curve)and an IOS(impulse oscillometry) system before and after Bronchial Diulation Test,The spirometric indexes such as forced vital capacity,total respiratory impedance,respiratory resistance and respiratory system reactance were collected and analyzed. Results Significant decreases of indexs were found after Bronchial Diulation Test compared with those before Bronchial Diulation Test in the study group(P<0.05,respectively). No significant difference in improvement of indexs was found between the group of patients with senile asthma(age > 60 years)and the group of healthy control(age < 60 years ). Each index of the airway resistance has a very good correlation with FEV1%,with the highest degree of relation is X5%. Conclusion The airway resistance of senile asthmatic patients was significantly improved after diuslation test and these indexes IOS would be valuable in evaluating the changes of airway resistance of senile asthma.

Endoplasmic reticulum (ER), a multifunctional organelle in eukaryotic cells, is responsible for protein synthesis and intracellular signal transduction, which dominates cell function, survival, and apoptosis. Disequilibrium of ER homeostasis may induce ER stress, which closely intertwines with tumor occurrence and progress. A few clinical-used drugs (such as anthraquinones and oxaliplatin) can mediate the immunogenic cell death of tumor cells through excessive ER stress, and sequentially stimulate anti-tumor immune responses as well as long-term immune memory. However, these drugs often exhibit poor targeting ability and extremely low ER accumulation in tumor cells, limiting their clinical efficacy. Therefore, the researches of ER-targeted delivery of these drugs will significantly benefit the efficient and precise anti-tumor immunotherapy. In this review, we introduce the relationship between ER and tumor immunity, and summarize the ER targeting strategies for anti-tumor immunotherapy in recent years. Furthermore, we discuss the problems of existing ER targeting strategies and look into its broad prospects of application.
