Malnutrition is one of the most important factors for the prognosis of patients with gastric cancer,but the mechanism of malnutrition is unclear at present. These patients are at risk of nutritional deple-tion from anorexia,dysphagia,and may be associated with the presence of two or more of the following cyto-kines with metabolic activity such as TNF-α,IL-1,IL-6,interferon,leptin,nuclear factor-κB and so on, which are secreted by the host-tumor interaction. The cytokines constitute a sophisticated regulatory network. Therefore,the study of the relationship between malnutrition and related factors in patients with gastric cancer may improve the nutritional status and prognosis of these patients.

Objective To evaluate the efficacy and safety of topotecan(TPT) in the treatment of advanced epithelial ovarian carcinoma. Methods 84 patients with advanced epithelial ovarian carcinoma received TPT(1.25mg/m~2) as a 30-minute infusion daily for 1-5 days,21 days for a cycle.The efficacy was evaluated after 2 cycles of chemotherapy.Response was confirmed 4 weeks later.Results In 84 selected patients,72 were assessable for response and 84 for toxicity.The overall response was 22.2%,including 2 CR and 14 PR.The response rate for untreated and recurrent advanced epithelial ovarian carcinoma was 25.0% and 20.8%,respectively.The main side effects were neutropenia and leukopenia.WHO grade III-IV of them were 26.1% and 26.1%,respectively.The non-hemotological toxicity was mild.Conclusion TPT is effective and well-tolerated in the treatment of advanced epithelial ovarian carcinoma,especially in recurrent patients.

Objective To explore the value on the treatment of severe acute pancreatitis (SAP) by hemofiltration combined with Dan Sen and catheterizing drainage through laparoscope. Methods Thirty patients of SAP were divided into two groups. On the basis of routine treatment(supportive treatment,suppressing excrine of pancreas stilamin,trypsin inhibitor and antibiotics),hemofiltration,catheterizing drainage,stilamin and Dan Sen were added in group A,while only routine treatment were administered in group B. TNF,IL-6,IL-8,score of Balthazar CT and score of APACHEⅡ were studied in both groups. Results The value of TNF,IL-6,IL-8,score of Balthazar CT and score of APACHEⅡ in group A were significantly lower than those in group B(P

Objective To establish an abdominal-trauma-induced uncontrolled hemorrhagic shock (UHS) model, and explore the effect of staged resuscitation. Methods Indwelling catheters were inserted into left ventricle, femoral artery and femoral vein of 50 Sprague-Dawley rats, and then laparotomy was performed. 42 out of the 50 animals were subjected to vascular injury to simulate UHS by infra-renal arterial puncture with 25G needles, and the model was successfully established in 32 rats, for which the animals were divided into 3 groups: control group (n=10), with no resuscitation; hospital-resuscitation group (n=11), resuscitated in early injured stage; and staged-resuscitation group (n=11), resuscitated pre-hospital and then in-hospital. 8 out of the 50 rats, which were not subjected to vascular injury, served as sham-operated group. The mean aortic pressure (MAP), central venous pressure (CVP), serum lactic acid, alanine aminotransferase (ALT) and creatinine (Cr) were determined, and the volume of blood loss and survival time were recorded. Results The MAP decreased from 94.7mmHg to 28.9mmHg 15min after aortic injury in control group and rose slowly after continuous transfusion in staged-resuscitation group. Similar change was found in CVP. Serum lactic acid, ALT and Cr were increased in control group and hospital-resuscitation group at early injured stage, but the increase was delayed in staged-resuscitation group. The mean survival time in control group, hospital-resuscitation group and staged-resuscitation group were 76, 846 and 2480 min, respectively. The 72 h mortalities of the three groups were 100%, 72.7% and 36.4%, respectively. Conclusion Staged resuscitation which is characterized by slowly continuous transfusion at early aid stage cannot increase the blood pressure and circulating blood volume to normal level in UHS, but can reduce the level of serum lactic acid, ALT and Cr, and dose not increase the blood loss. The survival rate and mean survival time can be increased by this method.

0.05) . NNS could decrease blood viscosity and hematocrit, inhibit the aggregation of erythrocytes and platelet and increase the activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH -Px). [Conclusion] NNS has an effect on AIS, which is similar to nimodipine. Its therapeutic mechanism may be related to the relief of cerebral ischemia by improving blood rheology and cerebral blood flow and protecting brain cells from injury by eliminating free radicals.

[Objective] To explore the protective mechanism of Naoxing Nasal Spray (NNS) on ischemic cerebral injury. [Methods] Seventy Wistar rats were randomized into 7 groups: high-dose NNS group (group A), moderate-dose NNS group (group B), low-dose NNS group (group C), nimodipine group (group D), model group (group E), solvent control group (group F) and pseudo-operation group (group G). Rat models of ischemia/reperfusion were established by blocking left middle cerebral artery. Plasma levels of tumor necrosis factor a (TNF-?) and interleukin 1? (IL-1?), malondialdehyde (MDA) content, activities of superoxide dismustase (SOD), glutathione peroxidase (GSH-Px) and nitric oxide synthase (NOS) in brain homogenate were detected. [Results] NNS decreased the contents of MDA, TNF-? and IL-1?, and increased the activities of SOD, GSH-Px and NOS. [Conclusion] NNS has protective effect on ischemic cerebral injury by promoting the clearance of free radicals, inhibiting the release of inflammatory mediator and increasing the synthesis of NO and thus to reduce injury of free radicals, inhibit the local inflammatory reaction and improve cerebral blood perfusion.

Objective To evaluate the prognostic value of combining postprocedural fibrinogen with high-sensitivity C-reactive protein (hs-CRP) in first time ST elevated myocardial infarction (STEMI) patients who had underwent successful primary percutaneous coronary intervention (PCI).Methods A total of 183 consecutive patients who had their first acute STEMI attack and underwent successful primary PCI were enrolled. Fibrinogen and hs-CRP levels were measured within 12 hours after PCI. All patients were followed up for 2 years. The primary end point was death of any cause. The secondary end point was a combined end point of death, non-fatal MI, heart failure (NYHA Ⅲ~Ⅳ),myocardial ischemia confirmed by stress test and revascularization. Results Postprocedural fibrinogen level correlated with hs-CRP level linearly (r=0.452, P

Objective To study the early resuscitation with intravenous administration of liquor in uncontrolled hemorrhagic shock model by four-staged abdominal aorta injury in rats in order to settle the controversy over the issue of volume resuscitation.Method Forty Sprague-Dawley rats were canulated with catheters into the left ventricle,femoral artery and femoral vein,respectively.Animals were subjected to vaseular injury of infrarenal pierced with a 25G needle leading to uncontrolled hemorrhagic shock.After aorta injury,the models were processed into 4 stages:early injured stage,early rescue stage,delayed rescue stage and observation stage.The rescue with rapid infusion of 45 ml/kg lactated Ringer's solution in 15 minutes in the early stage and the followed rescue in the late stage;and(4)sham-rescued.The MAP,CVP,lactic acid and Hct were monitored.The volume of blood loss and the survival time of rats were recorded too.Results After aorta injury,The MAP dropped from 94.3 mmHg to 25.8 mmHg and rised quickly after early resuscitation with rapid infusion of liquor and then again fell soon,and CVP did likewise.Lactic acid was increased and reached 3-4 times of baseline at 4 h in all group except Sham-resuced group.The Hct levels decreased quickly after resuscitation with liquor in early rescue stage and delayed rescue stage.The blood loss in abdomen increased after rapid infusion of lactated Ringer's solution in early rescue stage(blood loss increased from 22.8 ml/kg to 27.7ml/kg,P＜0.05).There Was no significant difference in mortality between those groups.Conclusions Rapid volume resuscitation at early stage of abdominal aorta injured with uncontrolled hemorrhagic shock cannot increase the circulatory blood volume for maintaining stable blood pressure norminimize the elevation of blood lactic acid.On the contrary,resuscitation with rapid administration of liquor at early stage can enhance blood loss and decrease the level of Hct.The survival time and survival rate can't be increased by early rescue with rapid liquor infusion.
