Objective To investigate the safety and effectiveness of laparoscopic surgery for early ovarian cancer. Methods Selected 90 early-stage ovarian cancer patients from January 2010 to December 2014 in Zhejiang Cancer Hospital as research subjects, and randomly divided into laparoscopic surgery group and laparotomy group. Then compared the age, BMI, ovarian cancer diameter, ovarian cancer staging, blood loss, operative time, surrounding or﹣gan damage, albumin difference before and after surgery, postoperative ventilation time, postoperative hospital stay, interval of postoperative to the first chemotherapy, postoperative fever cases, follow-up time, postoperative complica﹣tions, postoperative recurrence and postoperative death in two groups. Results Blood loss and operative time of la﹣paroscopic surgery group was less than that of laparotomy group (P< 0.05). Albumin difference before and after surgery of laparoscopic surgery group was less than that of laparotomy group (P< 0.05), postoperative ventilation time and interval of postoperative to the first chemotherapy of laparoscopic surgery group was less than that of la﹣parotomy group (P< 0.05), the incidence of postoperative fever and postoperative complications of laparoscopic surgery group was less than that of laparotomy group (P< 0.05), the recurrence rate and postoperative mortality rate of laparoscopic surgery group were slightly higher than that of laparotomy group, but the difference was not statisti﹣cally significant (PP> 0.05). Conclusion Laparoscopic surgery for early-stage ovarian cancer has a relatively good safety and efficacy. Laparoscopic surgery has advantages over open surgery in improving early ovarian cancer intra﹣operative situation and postoperative situation.

Ovarian cancer is one of the highest mortality rate of gynecologic malignant tumors. Chemotherapy can improve the survival rate of the traditional ovary. In recent years, PARP [poly(ADP-ribose)polymerase]inhibitors in breast cancer susceptibility gene (breast cancer susceptibility gene, BRCA) mutations in patients with ovarian cancer can significantly improve the disease-free survival, may change the prognosis of patients with ovarian cancer. This part of PARP [poly(ADP-ribose)polymerase] inhibitors, inhibiting the repairment of DNA damage in tumor cell, causing DNA damage accumulation, eventually killing tumor cells.In breast cancer susceptibility gene 1 (breast cancer susceptibility gene1, BRCA1)/BRCA2 mutation patients with ovarian cancer, PARP inhibitors and BRCA mutation of the synthetic lethal effect provides a new direction for the development of anti-cancer drugs. Now, many highly selective and sensitive PARP inhibitors have been developed and applied in clinical trials.Although PARP inhibitor monotherapy can produce a therapeutic effect in BRCA mutation in patients with ovarian cancer, but the clinical application is still used in combination with other chemotherapy or radiotherapy. This review is focused on the recent progress in clinical trials of PARP inhibitors in combination with common chemotherapeutic agents.

OBJECTIVE: To explore the diagnostic value of brain natriuretic peptide (BNP) level in patients with sepsis of blood-stasis syndrome. METHODS: The prospective method of clinical diagnostic test and evaluation principles of diagnostic test were applied. One hundred and seventy-four patients with sepsis were divided into two groups: blood-stasis syndrome group and non blood-stasis syndrome group. The levels of serum BNP in two groups were detected. RESULTS: The level of BNP in sepsis patients was related to blood-stasis syndrome (P<0.01). BNP cut-off level was 150 ng/L, sensitivity was 85.3%, specificity was 81%, the maximum value of Youden index was 0.663, and the area under the receiver operating characteristic curve (ROC) value was (0.886+/-0.025). CONCLUSION: BNP can be used as an objective index of blood-stasis syndrome diagnosis for sepsis, and BNP with boundary value of 150 ng/L is an optimal biological index.

Objective To compare the results of locking intramedullar nail and Locking plate in treating proximal humerus fractures and discuss features of each instrument. Methods A total of 54 patients with fresh two-part surgical neck fracture of proximal humerus were divided into intramedullar nail fixation group(26 patients)and locking plate fixation group(128 patients).with no statistical difference upon age,gender and dominate hand involvement in two groups.At final follow-up,physical examination and X-ray films were used to evaluate fracture healing of shoulder ioint.In the meantime,VAS score,ASES score,Constant-Murley score,UCLA and SST questionnaire were used to evaluate the function of the shoulder in two groups. Results All fractures were healed basically within 8 weeks postoperative-ly.No infection or av&scular necrosis were fouml during follow-up.The incidence rate of complication in locking plate fixation group was higher than that in intramedullar nail fixation group.Both groups obtained satisfactory functional recovery of shoulder ioint.There was no statistieal difference in regard to active for-ward elevation,external rotation besides body,active height of internal rotation,Constant-Murley scores,and SST scores in both groups.The average ASES score and VAS score of locking plate fixation group was significantly better than those of intramedullar nail fixation group. Conclusions Both fixations can treat surgical neck fractures of proximal humerus well.Locking intramedullar nail causes less trauma to the patient while Locking plate has advantages in patients'final functional recovery.

Tumor-associated macrophages (TAMs) exist in the tumor microenvironment,and can be affected by various anticancer treatments and further affect tumor progression.Increasing evidence suggests that many of the clinical antitumor measures can play a unique and effective antitumor effect by regulating the recruitment,polarization and related pro-tumor behavior of macrophages in the tumor microenvironment.Now,tumor microenvironment immune remodeling has become a hot spot in the research of anti-tumor therapy.This paper reviews the related research progress on antitumor effects of TAMs as an therapeutic target.

Blood GSHpx activities of populations living in Keshan disease affected and non-affected areas were examined. The enzyme activities of people in affected areas were lower than that in non-affected areas. That of agricultural population is lower than that of workers and staff members living in same affected areas. The enzyme activities of patient suffering from Keshan disease were a little lower than that of other children. After oral administration of Na2SeO3 for one year, the enzyme activities of children in affected areas increased to the same level of that in non-affected areas. Significant correlation was found between selenium concentration of blood and hair and GSHpx activities.

1. Experiments were conducted to compare the blood glutathione peroxi-dase activity of rats fed low selenium diets (0.0042 and 0.0084ppm Se) mainly composed of rice, corn and soybean grown in Keshan Disease endemic areas with that of rats fed the contrast diets (0.073 and 0.074 ppm Se) composed of the same grains grown in non-endemic areas and with that of rats fed stock diets (0.307 ppm Se). The enzyme activities of the endemic grain-feeding groups were lower than that of the non-endemic grain-feeding groups, but the enzyme activities of these groups were significantly lower than that of the stock diet group. The difference of the percentage of ascorbic acid-induced oxidation of hemoglobin to methemoglobin, choleglobin and Heinz bodies in vitro in different groups were in the same trend as that of the glutathione peroxidase activity.2. When rats were fed the low selenium diets for three months supplementing with sodium selenite, both the blood selenium levels and glutathione peroxidase activities were increased to the levels of the stock diet group within 50 days.

Objective To evaluate the results of delayed proximal humeral fractures treated by open reduction and internal fixation. Methods From January 2005 to July 2008, 26 patients with delayed proximal humeral fractures were treated by open reduction and internal fixation. There were 11 males and 15 females. The patients ranged from sixteen to 22-81 years old, with an average age of 49.3 years. The interval from injury to operation ranged 22 to 510 days, with a mean of 88 months. There were two-part fractue in surgical neck in 12 cases, two part in lesser tubercles of in one case,two part in greater tubercles in seven cases, three part in greater tubercles in three cases, four part in 2 cases and the splitting fracture in the head of humerus in one ease.The range of motion, VAS for pain, ASES (American sboulder and elbow surgeon's form) score, Constant score, UCLA (University of California-Los Angels scoring system)score and SST(Sim-pie Shoulder Test) for function evaluation were all recorded. The results were evaluated according to sex,age, injury side, operation times and combined injury by ANOVA.The correlation analysis was performed between operative time and results. Results The average forward flexion was 137.3°±35.1°, average exter-nal rotation was 28.9°±24.1° and internal rotation was T_(10). The mean VAS score was 0.7±1.2, the mean Constant was 83.1±17.9, the mean UCLA was 28.9±6.0, the mean SST was 8.7. There were no difference re-gaming sex, age, injury side, operation time and combined injury, fracture type and complications groups. No correlation existed between operative time and results. Conclusion It is very hard to treat delayed proximal humeral fracture due to high complication and demanding experience. With appropriate surgical technique, satisfactory results can be expected by open reduction and internal fixation.
