Objective The aim of this study is to evaluate the safety and efficacy of partial pancreatectomy as part of primary cytoreductive surgery in advanced epithelial ovarian cancer (EOC). Methods A total of 8 patients were recruited in this study who underwent partial pancreatectomy during the primary cytoreductive surgeries for advanced EOC in Fudan University Shanghai Cancer Center from April 2009 to July 2015. Their clinicopathological characteristics, diameter of metastatic tumors, the scope of cytoreductive surgeries, residual diseases after cytoreductive surgeries, postoperative complications and survival situation were retrospective analyzed. Results (1) Clinicopathological characteristics:the median age of these patients was 58 years old(range: 39-63 years old). The median value of preoperative serum CA125 was 1 688 kU/L(range: 119-5 000 kU/L). The median diameter of metastatic tumors involved in pancreatic body or tail was 4.5 cm (range:3-10 cm). All the tumors from the 8 patients were confirmed to be high-grade serous carcinoma. Four patients were staged as International Federation of Gynecology and Obstetrics (FIGO)Ⅳ, and the other 4 patients were staged as FIGOⅢc. (2) Tumor metastases and the scope of cytoreductive surgeries:all of these 8 patients had widely disseminated ovarian cancer, with involvement of upper abdominal, middle abdominal and pelvic cavity. Each patient underwent extensive intra-abdominal cytoreductive surgeries, including hysterectomy, bilateral salpingo-oophorectomy, omentectomy, pelvic periton-ectomy, splenectomy, partial pancreatectomy. Each patient had cytoreductive surgeries of 9.6 different sites on average. Of all 8 patients who underwent partial pancreatectomy, 7 patients had pancreatic tails removed;the other 1 patient had pancreatic body and tail removed. The median volume of blood loss during surgery was 1 350 ml(range:300-3 500 ml), blood transfusion was performed in 7 patients with the median volume of 1 150 ml (range: 500-1 800 ml). (3) Residual diseases after cytoreductive surgeries: optimal cytoreduction was achieved in all patients, with microscopic residual disease in 3 patients, residual tumors diameter < 0.5 cm in 3 patients, and residual tumors diameter between 0.5 and 1 cm in 2 patients. (4) Postoperative complications: 4 patients suffered from complications including pancreatic leakage (2/8), intraperitoneal hemorrhage (1/8) and pancreatic pseudocyst accompanied by infection (1/8). These complications were treated successfully by conservative managements. (5) Survival situation: during the median follow-up duration of 17 months (ranged from 2 to 46 months), 5 patients were still alive until the end of follow-up, including 4 cases under treatment and 1 case survived 29 months without relapse after treatment. Three patients were respectively died in 5, 20 and 46 months after surgery. Conclusion There is a higher risk of postoperative complications of pancreas resection as part of primary cytoreductive surgery in advanced epithelial ovarian cancer, but the resection of pancreatic metastases and part of the pancreas is feasible and necessary.

OBJECTIVE: To observe the correlation between the expression of galectin-7 and S100A9 with the development of cervical squamous carcinoma. METHODS: Immunohistochemical SP staining was used to detect the expression of galectin-7 and S100A9 in 243 patients with cervical intraepithelial neoplasia (CIN) or cervical squamous carcinoma. The association of clinical data with galectin-7 and S100A9 expression was examined. RESULTS: The expression of galectin-7 and S100A9 in CIN and cervical squamous carcinoma was significantly different (P<0.05). The positive rates of galectin-7 in normal cervical tissues, CIN I, CIN II, CIN III, and cervical squamous carcinoma were 56.7%, 41.9%, 32.0%, 27.3%, and 25.0%, respectively. Statistic analysis found significant difference between the normal cervical tissues and cervical squamous carcinoma (P<0.0045). The positive rates of S100A9 in CIN I, CIN II, CIN III, and cervical squamous carcinoma were 80.0%, 77.4%, 48.0%, 27.3%, and 20.2%. Statistic analysis showed significant difference between the normal tissues and CIN III, the normal cervical tissues and cervical squamous carcinoma, CIN I and CIN III, CIN I and cervical squamous carcinoma, CIN II and cervical squamous carcinoma (P<0.0045). A positive correlation was found between galectin-7 and S100A9 expression in CIN and cervical squamous carcinoma (rs=0.298, P<0.001). Expressions of both galectin-7 and S100A9 in cervical squamous carcinoma were associated with the clinical stage and lymph nodes (P<0.05), but not with patient's age and degree of differentiation (P>0.05). Expression of galectin-7 was associated with the survival rate of patients with cervical squamous carcinoma (P<0.05). Univariate analysis of Cox proportional hazards regression model revealed that the FIGO stage, lymph nodes metastasis, and the expression of galectin-7 were relevant to the 5 year survival rate of patients with cervical squamous carcinoma, which was confirmed by multiple analysis of Cox proportional hazards regression model. CONCLUSION Expression of galectin-7 and S100A9 is related with cervical the tumorigenesis of carcinoma, clinical stage, and lymph nodes of cervical squamous carcinoma. Galectin-7 is probably associated with the prognosis. The long-term survival of patients with cervical carcinoma may be associated with FIGO stage, lymph node metastasis, and the expression of galectin-7.

OBJECTIVE: Distal pancreatectomy with splenectomy may be required for optimal cytoreductive surgery in patients with epithelial ovarian cancer (EOC) metastasized to splenic hilum. This study evaluates the morbidity and treatment outcomes of the uncommon procedure in the management of advanced or recurrent EOC. METHODS: This study recruited 18 patients who underwent distal pancreatectomy with splenectomy during cytoreductive surgery of EOC. Their clinicopathological characteristics and follow-up data were retrospectively analyzed. RESULTS: All tumors were confirmed as high-grade serous carcinomas. The median diameter of metastatic tumors located in splenic hilum was 3.5 cm (range, 1 to 10 cm). Optimal cytoreduction was achieved in all patients. Eight patients (44.4%) suffered from postoperative complications. The morbidity associated with distal pancreatectomy and splenectomy included pancreatic leakage (22.2%), encapsulated effusion in the left upper quadrant (11.1%), intra-abdominal infection (11.1%), pleural effusion with or without pulmonary atelectasis (11.1%), intestinal obstruction (5.6%), pneumonia (5.6%), postoperative hemorrhage (5.6%), and pancreatic pseudocyst (5.6%). There was no perioperative mortality. The majority of complications were treated successfully with conservative management. During the median follow-up duration of 25 months, nine patients experienced recurrence, and three patients died of the disease. The 2-year progression-free survival and overall survival were 40.2% and 84.8%, respectively. CONCLUSION: The inclusion of distal pancreatectomy with splenectomy as part of cytoreduction for the management of ovarian cancer was associated with high morbidity; however, the majority of complications could be managed with conservative therapy.

Asiatic acid (AA), a pentacyclic triterpene found in, displays significant anti-proliferative effects on cancer cellsalthough the underlying mechanism of this effect remains unknown. This study investigated the efficacy and mechanism of action of AA against lung cancer bothand. Using the MTT assay, AA was found to induce apoptosis in a dose- and time-dependent manner, an effect enhanced by pretreatment with an autophagy inhibitor. It also elevated expression of microtubule-associated protein 1 light chain 3 (LC3) and decreased the expression of p62. Furthermore, exposure to AA resulted in collapse of the mitochondrial membrane potential and generation of reactive oxygen species (ROS), suggesting mitochondria are the target of AA. In the mouse lung cancer xenograft model, oral administration of AA significantly inhibited tumor volume and weight accompanied by significant apoptosis of lung cancer cells. In addition, it led to a significant decrease in the expression of proliferating cell nuclear antigen (PCNA). In summary, the results show that AA significantly reduces lung cancer cell growth bothandand that the associated apoptosis is mediated through mitochondrial damage.

To test the therapeutic effect of recombinant fusion polypeptide hEGF-AWRK6 (EK) on burn infection of model mice. EK6 was expressed and purified with Escherichia coli expression system, and the Ⅱ degree burns and Pseudomonas aeruginosa infection model mouse were established. Experiment group was treated with EK (30 mg/L), and the control group was treated with PBS, gentamicin (30 mg/L), burn ointment (10 mg/L). The wound healing rate and colony count were calculated. Wound and surrounding skin were taken for HE staining and collagen western-blot analysis, and the wound pathological changes were observed after 10 days of drug delivery. The results showed that fusion peptide EK was successfully expressed and purified with significant antibacterial activities against Pseudomonas aeruginosa. Compared to the control group, the colony count (CFU) of the wound surface in EK mouse had a remarkable decrease (P<0.01) and healing rate had a significant increase in group EK6 (P<0.01). Pathological analysis result showed that compared to the control group, wound dermal cells in group EK arranged regularly, had more hair growth and a faster epithelization. These results indicated that the fusion peptide EK would be a good candidate for the drug development for the treatment of burning wounds.
