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.

Recurrent anterior shoulder instability is a common problem we have to deal with in clinic. With the progress in shoulder and elbow surgery, there have appeared many new concepts about the etiology, diagnosis and treatment of this disease. About 2 decades ago, people realized the important role of glenohumeral ligaments. Now we believe that the stability of the glenohumeral joint relies heavily on the congruent articulating surfaces and surrounding soft tissues that act as static and dynamic stabilizers. Many new methods, such as MRI, physical examination under anesthesia and arthroscopy, can help us diagnose the disease accurately. Moreover, substantial progress has been made in the treatment of anterior shoulder instability. Open Bankart repair has become the golden standard for the treatment. With the advance of techniques, however, arthroscopic stabilization of anterior shoulder instability can now achieve good results comparable with those of open surgery.

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.

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 investigate and compare the biomechanical stability between anatomical and overlapping reconstruction of the greater tuberosity in cadaveric humeral head replacement model. Methods Eight pair (16) fresh-frozen shoulder cadavers were match-paired into 2 groups. Four-part fracture model was created in all cadavers. Standardized humeral head replacement procedure was carried out in all specimens, and anatomical and overlapping reconstruction of the greater tuberosity was applied to each group respectively. Custom mounting apparatus and fixation jigs were designed for designated shoulder motion. A Binocular 3D Computer Vision metrical method was employed to measure the displacement of greater tuberosity relative to the humeral diaphysis. Results When the shoulder was external rotated to neutral position, the mean displacement of greater tuberosity in anatomical reconstruction group was (1.81?1.75) mm,while the mean displacement was (3.23?2.91) mm in overlapping group. Statistical difference was found between the 2 groups. When the glenohumeral joint was elevated to 30? and 60? forward flexion, the mean displacement of greater tuberosity in anatomical group was (4.01?5.00) mm and (5.99?6.97) mm respectively, while the mean displacement was (3.02?5.27) mm and (6.97?7.00) mm respectively in overlapping group. No statistical difference was found between the 2 groups during forward flexion measurement. Conclusion In cadaveric humeral head replacement model, anatomic greater tuberosity reconstruction shows better mechanical stability compared with overlapping reconstruction during external rotation to neutral position. This result suggests that there may be some loss in mechanical stability in overlapping fixed greater tuberosity. Even though standardized postoperative rehabilitation protocol are strictly followed, evident displacement of the greater tuberosity was detected. Postpone of the postoperative rehabilitation program after humeral head replacement for a decent period of time may benefit tuberosity healing.
