Methods Rats were dosed orally and i.p. with a single dose of 14^C-deltamethrin （0.64 mg/Kg） body weight. The required dose was applied daily for 3 days. At the end of the experiment, selected organs, such as liver, kidney, fat, intestine, and blood were excised for radioassay of 14^C-content. Results Deltamethrin was almost eliminated from the body within 1-3 days. The main portion of 14^C-residues was extracted from urine （38%, 32%） and feces （20%, 24%） with a little amount remained in various organs. Conclusion The elimination and distribution of 14^C-radioactivity in rats treated orally and intraperitoneally signify that deltamethrin is bioavallable in urine and feces.展开更多

Treatment of diabetes involves diet, exercise, education and for most people, drugs. Oral antidiabetic drugs and/or insulin doses may be affected by co-administration of many drugs including aspirin. Dose adjustments may be necessary. The pain killer effect of aspirin is best known for its effects on the two cyclooxygenase enzymes (COX1 & COX2), but, recently, aspirin could specifically inhibit the protein I-kappa-β-kinase beta (IKK-beta). This kinase is used for its role in the cascade of signals that activate the nuclear factor kappa-b (NF-kappa-B) family of cellular genes which regulate inflammatory and immune responses. Now, it turns out that IKK-beta also works in another pathway to contribute to insulin resistance by interfering with insulin signaling. Objective: In view of the recent rodent data demonstrating a potentially important role of IKKβ in mediating insulin resistance and the ability of salicylates to inhibit IKKβ activity, we decided to examine the role of different doses of aspirin (low, moderate and high) in experimentally induced diabetic rats. Materials and Methods: DM in rats were induced by administration of nicotinamide (NAD), 15 min prior to the single dose of streptozotocin STZ i.p. Ninety male albino rats were used in this study. They were divided into 6 main groups. The first was served as control which receives no medications. The second group was diabetic induced rats as mentioned above. The third group was controlled by insulin after induction of D.M. Groups from the fourth to the six consist of 20 diabetic induced rats and further subdivided into rats taking either aspirin alone in different doses (low, moderate or high) or aspirin and insulin. At the end of the protocol, fasting blood sugar level (FBS), glycosylated hemoglobin (HBA1c%), total serum proteins, C-peptide, lipid profile and C-reactive proteins were measured. Result展开更多

The prognosis of PC patients treated by conventional systemic chemotherapy is poor, with a median survival of < 6 mo. However, over the past three decades, an integrated treatment strategy of cytoreductive surgery(CRS) + hyperthermic intraperitoneal chemotherapy(HIPEC) has been developed by the pioneering oncologists, with proved efficacy and safety in selected patients. Supported by several lines of clinical evidence from phases Ⅰ, Ⅱ and Ⅲ clinical trials, CRS + HIPEC has been regarded as the standard treatment for selected patients with PC in many established cancer centers worldwide. In China, an expert consensus on CRS + HIPEC has been reached by the leading surgical and medical oncologists, under the framework of the China Anti-Cancer Association. This expert consensus has summarized the progress in PC clinical studies and systematically evaluated the CRS + HIPEC procedures in China as well as across the world, so as to lay the foundation for formulating PC treatment guidelines specific to the national conditions of China.展开更多

Traditionally, PC was treated with systemic chemotherapy alone with very poor response and a median survival of less than 6 too. With the establishment of several phase Ⅱ studies, a new trend has been developed toward the use of CRS plus IPHC as a standard method for treating selected patients with PC, in whom sufficient cytoreduction could be achieved. In spite of the need for more high quality phase Ⅲ studies, there is now a consensus among many surgical oncology experts throughout the world about the use of this new treatment strategy as standard care for colorectal cancer patients with PC. This review summarizes the current status and possible progress in future.展开更多

METHODS: From August 2006 to March 2008, the laparoscopic approach was used to perform CHIPC on 16 patients with malignant ascites induced by gastric cancer or postoperative intraperitoneal seeding. Each patient underwent CHIPC three times after laparoscopeassisted perfusion catheters placing. The first session was completed in operative room under general anesthesia, 5% glucose solution was selected as perfusion liquid, and 1500 mg 5 fluorouracil (5FU) and 200 mg oxaliplatin were added in the perfusion solution. The second andthird sessions were performed in intensive care unit, 0.9% sodium chloride solution was selected as perfusion liquid, and 1500 mg 5FU was added in the perfusion solution alone. CHIPC was performed for 90 min at a velocity of 450600 mL/min and an in flow temperature of 43 ± 0.2℃.RESULTS: The intraoperative course was uneventful in all cases, and the mean operative period for laparoscopeassisted perfusion catheters placing was 80 min for each case. No postoperative deaths or complications related to laparoscopeassisted CHIPC occurred in this study. Clinically complete remission of ascites and related symptoms were achieved in 14 patients, and partial remission was achieved in 2 patients. During the followup, 13 patients died 29 mo after CHIPC, with a median survival time of 5 mo. Two patients with partial remission suffered from port site seeding and tumor metastasis,and died 2 and 3 mo after treatment. Three patients who are still alive today survived 4, 6 and 7 mo, respectively. The Karnofsky marks of patients (5090) increased significantly (P < 0.01) and the general status improved after CHIPC. Thus satisfactory clinical efficacy has been achieved in these patients treated by laparoscopic CHIPC. CONCLUSION: Laparoscopeassisted CHIPC i展开更多

The definition of advanced gastric cancer is still debated. Different stadiating systems lead to slightly different stadiation of the disease, thus leading to variations between the single countries in the treatment and outcomes. In the present review all the possibilities of treatment for advanced gastric cancer have been analyzed. Surgery, the cornerstone of treatment for advanced gastric cancer, is analyzed first, followed by an investigation of the different forms and drugs of chemotherapy and radiotherapy. New frontiers in treatment suggest the growing consideration for intraperitoneal administration of chemotherapeutics and combination of traditional drugs with new ones. Moreover, the necessity to prevent the relapse of the disease leads to the consideration of administering intraperitoneal chemotherapy earlier in the therapeutical algorithm.展开更多

The incidence of PMP is believed to be approximately 1-3 out of a million per year. Nonetheless, due to its indolent nature, it is usually discovered at an advanced stage and severely impacts quality of life. Curative treatment for PMP is complete cytoreductive surgery(CRS) with hyperthermic intraperitoneal chemotherapy(HIPEC). An extensive literature review was conducted searching EMBASE, MEDLINE, Pub Med, and Google Scholar databases for PMP in aims to delineate a clinical approach to diagnosis and treatment. Literature was limited to the years 2007-2018. We found the 5-year overall survival with CRS and HIPEC estimated to be between 23%-82% and rates of major complications as high as 24%. Therefore, it is important to appropriately stage and select patients that should undergo CRS with HIPEC. Modalities like MDCT radiological scores have been shown to have sensitivity and specificity of 94% and 81%, respectively, in being able to predict resectability and survival. Despite treatment, the disease often recurs. Tumor markers have significant potential for establishing prognosis preoperatively, and this paper will review the most recent evidence in support of them.展开更多
