Anthracycline-based antitumor drugs are one of the highly effective broad-spectrum anti-cancer drugs that are commonly used clinically. However, anthracyclines have the serious side effect of cumulative dose-related cardiotoxicity. Clinically, intake of myocardial protective drugs is one of the most important strategies for the safe use of anthracyclines in chemotherapy. Numerous cancer patients un-dergoing chemotherapy also require surgery, during which general anesthesia is commonly used. Various studies have shown that propofol and sevoflurane, the most commonly used general anesthetics, present a significant protective effect in myocardial ischemia-reperfusion damage. Therefore, for patients who have just undergone chemotherapy with anthracyclines, anthracycline-induced myocardial injury may occur at the acute or chronic phase of surgery. Consequently, if the effect of anesthetics on the cardiotoxicity of anthracyclines is similar to the protective effect of these drugs for myocardial ischemia-reperfusion damage, this protective effect on cardiotoxicity will have significant impact on the recovery of cardiopulmonary function of patients after surgery. Thus, further studies are needed to establish the effect of anesthetics on the cardiotoxicity of anthracyclines.

Objective To investigate effect of propofol total intravenous anesthesia and sevoflurane inhalation anesthesia on perioperative inflammatory response in patients with lung cancer.Methods Forty patients with simple resection of lung cancer were selected in our hospital.They were divided into observation group and control groups according to random sampling method (n=20).Observation group was given propofol total intravenous anesthesia while control group received sevoflurane inhalation anesthesia.The serum concentrations of MMP-9,TNF-α,IL-6 were compared at the T0 (immediately before the induction of anesthesia) , T1 (1 hour after surgery) , T2 (end of the surgery immediately) , T3 (24 hour after surgery) . Results Compared with the T0 period,the serum concentrations of MMP-9,TNF-αand IL-6 at the T1,T2,T3 periods were increased significantly in the both groups(P<0.05);the concentrations of TNF-α, IL-6 were lower significantly in observation group compared with control group (P<0.05) . Conclusion Propofol anesthesia for resection of lung cancer patients can significantly reduce the inflammatory response.

Objective To compare the synchronous primary endometrial and ovarian carcinomas with primary endometrial cancer with ovarian metastasis through analysis the general condition, clinical features, pathologic result,treatment and the prognosis of the two diseases. Methods 24 patients with synchronous primary endometrial and ovarian carcinomas and 27 patients with primary endometrial cancer with ovarian metastasis in Shanxi Cancer Hospital from January 2000 to January 2015 were collected. Results There were statistical significance among age, menopause or not, clinical symptoms, ascites, vascular tumor emboli, tumor differentiation, lymph node metastasis and the prognosis between the two groups (all P< 0.05). The patients with synchronous primary endometrial and ovarian carcinomas were younger, had pelvic mass and stomachache, less ascites, no vascular tumor emboli, well tumor differentiation, no lymph node metastasis. They had better prognosis compared with patients with primary endometrial cancer with ovarian metastasis. Conclusions Patients with synchronous primary endometrial and ovarian carcinomas are younger than patients with primary endometrial cancer with ovarian metastasis,and more early stage, the excessive treatment should be prevented. They have better prognosis compared with patients with primary endometrial cancer with ovarian metastasis.

Poly ADP-ribose polymerase(PARP)inhibitor is a targeted biological agent for the treatment of ovarian cancer, which is mainly suitable for platinum-sensitive ovarian cancer patients. However, data from clinical trials showed that PARP inhibitors have certain therapeutic effect on platinum-resistant or platinum-refractory ovarian cancer patients. It may become a new hope for treatment of ovarian cancer patients in the future.

Objective: To study the relationship of the expressions of new apoptosis-related gene (PDCD)5 and p53 in oral normal mucosa, oral leukoplakia and oral squamous cell carcinoma. Methods: The expressions of PDCD5 and p53 were observed separately in 17 samples of oral normal mucosa, 60 of oral leukoplakia, and 30 of oral squamous cell carcinoma by Immunohistochemical means. Results: PDCD5 positive rate in oral normal mucosa was 88.2%, in oral leukoplakia was 63.3%, and in oral squamous cell carcinoma was 30%. P53 positive rate in oral normal mucosa was 0, in oral leukoplakia was (31.7%), and in oral squamous cell carcinoma was 60%. There was a negative relationship between (PDCD5) SII and P53 SII in every lesion. Conclusion: It suggests that both PDCD5 and p53 could be used as molecular markers of carcinogenesis for oral epithelium.

BACKGROUND: Due to good biocompatibility, autologous bone has been considered as the optimal graft, but its source is too limited to meet the clinical requirements. In addition, the harvesting of iliac bone is associated with significant morbidity, thus searching for a substitute material of autologous bone graft is a current topic of study.OBJECTIVE: To study the biocompatibility and osteogenesis capacity of autosolidifying calcium phosphate cement (CPC) in the repair of bone defects.DESIGN, TIME AND SETTING: A self-control observation was performed among 94 patients who were admitted at the Department of Orthopedics in Yiwu Central Hospital (Yiwu, Zhejiang, China) from February 2001 to September 2004.PARTICIPANTS: Ninety-four patients with bone defects were involved in this study. The underlying cause of bone defects was fracture collapse and reduction in 63 cases, osteomyelitis in 20 cases, bone cyst in 6 cases, fibrous dysplasia in 4 cases and enchondroma in 1 case. The area of bone defects ranged from 1cm×1cm to 4cm×20cm.METHODS: CPC was the product of Shanghai Rebone Biomaterials Co., Ltd (License N0. 2005-3460304, China). CPC powder was mixed with solidifying liquid according to the ratio of 3.0g: 1mL, and the filling dose of CPC was 3-42g. There were 74 cases implanted with pure CPC, including 38 cases with thoracolumbar fracture undergoing vertebroplasty, 25 cases with fracture undergoing open repair, and 11 cases underwent focal debridement of benign bone tumor. in another 20 cases of osteomyelitis, drug-loaded CPC was implanted.MAIN OUTCOME M[EASURES: After the CPC implantation, all patients were observed according to the following indexes: allergic or toxic reaction, rash or high fever, levels of serum calcium, phosphors and alkaline phosphatase. X-ray radiography at month 12 after implantation was employed to observe the osseointegration of the implanted CPC to host bone and the degradation of CPC.RESULTS: All 94 patients were followed up for 14 months, and 76 of them for 24 months, 47 of them for 36 months, and 36 of them for 48 months. CPC developed primary solidification in human body within 30 minutes. Neither allergic or toxic reaction nor rash or high fever were found in all patients. The levels of serum calcium, phosphors and alkaline phosphatase were noted to be normal. No case companied with the itching in incision. The radiological examination showed that. the implanted CPC was directly bonded to the bone at the interface, and the bone contour at the defect sites was completely or partly restored. Degeneration and new bone were formed in some of the patients. Incision oozing light yellow fluids occurred in 9 cases, the bacterial culture was detected as negative, and all wounds healed through dressing changes. In the 20 cases implanted with drug-loaded CPC, no cases experienced recurrence of osteomyelitis and CPC degeneration was not complete.CONCLUSION: With good biocompatibility, safety and few complications, CPC is a good substitute for autologous bone graft in the repair of bone defects, and drug-loaded CPC is a selective treatment for osteomyelitis.
