Objective To evaluate the efficacy and toxicity of weekly docetaxel and cisplatin in previously untreated patients with advanced non-small-cell lung carcinoma. Methods Between January 2002 and December 2003 ,34 patients with pathologically comfirmed advanced non-small-cell lung carcinoma who had not received treatment were enrolled. The mean age was under 66 years. The patients received intravenous infusions of docetaxel(25 mg/m2,dayl ,8,15) with dexamethasone premedication and cisplatin(25 mg/m2,dayl ,8,15) ,followed by a week of rest. The remedies which were less than 6 regimens lasted to disease progression or severe toxicity. Therapeutic effect was evaluated by CT scan every two courses . The patients were followed up for 24 months. Descriptive statistics and SPSSIO. 0 software were used to analyse the results. Results 34 patients finished 90 courses. The mean was 2. 6 courses. All patients were followed up. Two patients achieved complete responses, ten patients achieved partial responses, ten patients achieved stable disease. An objective response rate of 35. 29% (95% confidence interval 19. 25%-51. 33% )was obtained. Patients life quality was significantly improved. The median time to progression was 4. 1 months, and median overall survival was 11 months. The 1-year survival rate was 47. 06% , the 2-year survival rate was 11.76% . Toxicities were mild. Grade 3 to 4 neutropenia (11.76%), anemia (5.88%), hyponatremia (5.88%), alopecie (17.64%) and nausea/vomiting (5. 88% ) were observed. Conclusion Weekly Cisplatin plus docetaxel is an effective and well-tolerated regimen in chemo-naive patients with advanced NSCLC. Well-designed clinical trials should be conducted.

Objective To compare the 7th edition of International Union Against Cancer ( UICC) staging system with the Chinese 2008 staging system for nasopharyngeal carcinoma ( NPC) , and to provide evidence for further updating of the staging system. Methods A retrospective analysis was performed among 767 patients who were pathologically and newly diagnosed with non?metastatic NPC and treated with intensity?modulated radiotherapy from 2006 to 2012. Based on the main prognostic indices, overall survival ( OS) , locoregional failure?free survival( LFFS) local relapse?free survival ( LRFS) , and distant metastasis?free survival ( DMFS) rates, the value of T stage, N stage, and clinical stage in prognostic prediction was compared between the two staging systems. The Kaplan?Meier method was used for calculating survival rates. The log?rank test was used for survival difference analysis. The Cox model was used for multivariate prognostic analysis. Results In terms of T stage, the Chinese 2008 staging system was a significantly better predictor of the OS and LRFS rates than the 7th edition of UICC staging system. In terms of N stage, they were comparable in the prediction of the OS and DMFS rates. In terms of clinical stage, the 7th edition of UICC staging system was a significantly better predictor of the OS rate than the Chinese 2008 staging system. For the new staging system proposed based on the statistical results, the T, N, and clinical staging gave significantly better prognostic prediction. Conclusions The 7th edition of UICC staging system and the Chinese 2008 staging system for NPC have their own advantages in prognostic prediction. The new staging system proposed in this study could contribute to the updating of the current staging system for NPC.

OBJECTIVETo explore the effect of berberine on lipid metabolism disorder and lipid deposition in liver cells of non-alcoholic fatty liver disease (NAFLD) rats induced by high fat diet.

METHODSAfter one week adaptable feeding, 45 SPF level male SD rats were randomly divided into 3 groups, the normal control group, the model group, and the berberine group, 15 in each group. Except those in the normal control group, all rats were fed with high fat diet to prepare NAFLD model. As for rats in the berberine group, Berberine Hydrochloride was administered by gastrogavage. HE staining and oil red O staining were performed to identify the model after 8 weeks. Hepatocytes were isolated, and their activities and purities were tested by Typan blue staining and flow cytometry (FCM). Serum levels of TC, TG, HDL-C, and LDL-C were detected using automatic biochemical analyzer. mRNA expression levels of LXRα and FAS in liver cells were analyzed by Real-time quantitative polymerase chain reaction (PCR). Protein levels of LXRα and FAS in liver cells were examined by Western blot.

RESULTSThe NAFLD rat model was successfully established by high fat diet. The yields of purified liver cells in each rat were (6.0-7.5) x 10(8). The viability of isolated liver cells with purity over 90% (tested by FCM analysis) was higher than 95%. Compared with the normal control group,the expression of LXRα and FAS at mRNA and protein levels was higher in the model group (P < 0.01). Compared with the model group, the expression of LXRα and FAS at mRNA and protein levels was obviously down-regulated in the berberine group (P < 0.01).

CONCLUSIONSLXRα/FAS signaling pathway was one of important signaling pathways of NAFLD lipid metabolism disorders. Berberine could recover hepatocyte fatty deposits in NAFLD rats by adjusting the LXR/FAS signaling pathway of hepatocytes, which might be one of important mechanisms for fighting against NAFLD.

OBJECTIVETo investigate the expression of human epidermal growth factor receptor 2 (HER-2/neu) in hepatocellular carcinoma (HCC) patients and its clinical significance.

METHODSThe expressions of HER-2/neu were detected by SP immunohistochemistry method in 30 patients with HCC, 10 with portal cirrhosis of the liver and 10 with normal liver.

RESULTSThe positivity rate of HER-2/neu was markedly higher in HCC patients than in those with portal cirrhosis and normal liver (Chi(2)=6.482, P=0.032). The expression of HER-2/neu was closely correlated to portal cirrhosis of the liver (P=0.041), tumor invasion (P=0.028) and Edmondson grades (P=0.012). The average survival time was significant shorter in patients with HER-2/neu-positive tumor than in those with HER-2/neu-negative tumor (P=0.036).

CONCLUSIONThe expression of HER-2/neu may play a role in the invasion, metastasis and progression of HCC. The patients positive for HER-2/neu in the HCC tissues have generally poor prognosis.

Objective To explore the effectiveness and safety of intravenous metoprolol by two injection methods in treatment for patients of atrial fibrillation anti rapid ventricular rates complicated with heart failure.Methods Patients of atrial fibrillation and rapid ventricular rates complicated with heart failure were administrated regular drug therapy for their heart failure,and then they were observed for half an hour.If their ventricular rates were above 100 beats/min and blood pressure equal to or above 100/60 mm Hg (1 mm Hg=0.133 kPa),they were randomly divided into three groups,the first one administrated with metoprolol 10 mg by minipump in an hour,the second one administrated with metoprolol 5 mg in 10 minutes by direct injection,and repeated by 5 mg 10 minutes later if their heart beats were still above 100 beats/min and blood pressure equal to or above 100/60 mm Hg,and the third one administrated with normal saline as control group.As either ventricular rates were equal to or lower than 60 beats/min or blood pressure lower than 90/60 mm Hg,drug administration would be terminated.Symptoms,physical signs, heart rate,blood pressure,rale on auscultation of the chest,parameters of haemodynamics,serum levels of brain natrium peptide (BNP) and atrial natrium peptide (ANP) were observed at 0 h and 1 h after drug injection.Results Clinical symptoms and physical signs of heart failure were improved significantly,heart rates and serum levels of BNP (F=15.929,14.534,all P

Objective To evaluate the therapeutic effect of comprehensive treatments for radiation-induced lower cranial neuropathy in patients with nasopharyngeal carcinoma (NPC). Meathods Fifty NPC patients with radiation-induced lower cranial neuropathy were randomly divided into comprehensive treatment group and control group. In the former group, the 25 patients received 10 sessions of hyperbaric oxygen treatment in addition to intravenous infusion of methyprednisolone (60-80 mg, once daily for 10 consecutive days) and aceglutamide (500 mg, once daily for 28 days), with also patients in the control group were given 2 compound vitamine B tablets and 3 compound Denshen tablets three times a day for 45 days. Results The excellent effect, improvement, non-response, and exacerbation rates in the comprehensive treatment group were 24%, 72%, 4%, and 0%, as compared to the rates of 0%, 12%, 80%, and 8% in the control group, respectively. The overall response rate in the comprehensive treatment group was 96%, significantly higher than that in the control group (12%, P<0.05). In the patients receiving comprehensive treatment, exclusion of chemotherapy and shorter duration of symptoms of nerve damage were associated with better therapeutic effect (P<0.05). Conclusion Methyprednisolone, mouse nerve growth factor and hyperbaric oxygen treatment can relieve the symptoms of radiation-induced lower cranial neuropathy in NPC patients, and the therapeutic effect of the treatments is associated with chemotherapy and sustaining time of the symptoms of nerve damage, suggesting the necessity of early treatment of neurological impairment in these patinets.

Objective　To investigate the role of bacterial DNA in systemic inflammatory response syndrome (SIRS). Methods　A total of 100 mice of Kunming species were divided into ten groups: E.coli DNA (30, 20, 10, 5 and 1 mg/kg ), 30 mg/kg of CT DNA, 60Co DNA, DNased DNA, organic residue of DNA extraction and sterile water control. The last two were pre-treated with D-galactoamine (600 mg/kg intra peritoneally). Animals were administratively injected via tail vein. General physical condition and the death rate of mice were observed within 48 h. Results　①Obvious lethal effect of double strand E.coli DNA on mice were observed with a dose-effect correlation, LD50=11.51 mg/kg. ②NO difference in death rate was found in the group of 30 mg/kg E.coli DNA with or without 60Co irradiation (10/10 and 8/10,P>0.05). ③No rats died in the group of DNased DNA, organic residue of DNA extraction and calf thymic DNA (0/10). Conclusion　Bacterial DNA may play an important role in the development of SIRS.

OBJECTIVETo study the impact of an agonist anti-CD(40) monoclonal antibody 5C11 on the induction and biological characteristics of leukemic dendritic cells.

METHODSCombinations of 5C11 and different cytokines were used to induce differentiation of leukemic blasts into dendritic cells. Morphology was observed by light microscopy. Surface antigens of the induced cells were analyzed by fluorescence-activated cell sorting (FACS), the yields of dendritic cell by cell counting, the levels of IL-6 and IL-12 by ELISA, T cell proliferating activity by allo-mixed lymphocyte reaction (MLR) in vitro. Allogeneic T cells were stimulated with leukemic dendritic cells and T-cell cytotoxicity was measured by MTT assay.

RESULTSWhen cultured with combinations of 5C11 and different cytokines, the leukemic cells isolated from the patients could differentiate into dendritic cells. The morphology showed typical features of dendritic cells, which expressed high levels of CD(40), CD(80) and CD(86). In comparison with the original leukemia cells, the leukemic dendritic cells secreted less IL-6 but more IL-12 (P < 0.05). The leukemic dendritic cells were potent to stimulate the proliferation of allogeneic T cells, and the latter was able to lyse the original leukemia cells.

CONCLUSIONLeukemic blasts could be induced to differentiate into functional dendritic cells. It may be of great value in the adoptive immunologic therapy of leukemia.
