Objective To study the level of serum vascular endothelial growth factor(sVEGF)in advanced non-small cell lung cancer(NSCLC) and its clinical significance.Methods Serum level of VEGF was detected by ELISA method in 96 patients with advanced NSCLC.sVEGF level was analyzed after giving 2-4 cycles of cisplatin-based chemotherapy.At the same time,serum level of VEGF in 50 healthy controls was detected.Results The level of sVEGF was significantly higher in patient with lung cancer than in control group (P＜0.01).No statistical significant defference was observed between sVEGF level of stage Ⅲ and Ⅳ NSCLC patients,the patients with squamocellular lung cancer and adenocarcinoma(P＞0.05);Descended sVEGF level was found in the patients with response to chemotherapy(P＜0.05).Conclusion sVEGF can be used to evaluate chemotherapy response and diagnoses in the patients with advanced NSCLC.

Objective To investigate the effects of parecoxib pretreatment on the intrapulmonary shunt during one-lung ventilation in patients undergoing esophageal cancer resection.Methods Forty ASA Ⅰ or Ⅱ patients of both sexes,aged 25-64 yr,weighing 45-70 kg,with body height 156-178 cm,undergoing elective esophageal surgery,were randomly divided into 2 groups (n =20 each):normal saline group (group NS) and parecoxib group (group P).Parecoxib 40 mg (in normal saline 10 ml) was injected intravenously 30 min before anesthesia in group P,while the equal volume of normal saline was given instead of parecoxib in group NS.Anesthesia was induced with iv injection of propofol,fentanyl and rocuronium.Bronchial blocker was inserted after tracheal intubation and the correct position was confirmed by bronchoscopy.Anesthesia was maintained with iv infusion of propofol and remifentanil and intermittent iv boluses of atracurium.HR,MAP,SpO2 and mean airway pressure (Pmean)were determined at 5 min of two-lung ventilation,at 40 min of one-lung ventilation,and at 30 min after re-expansion of the collapsed lung (T0-2).Blood samples were taken simultaneously from jugular vein and radial artery for blood gas analysis.Intrapulmonary shunt (Qs/Qt) was calculated.Results There were no significant differences in hemodynamic parameters and Pmean between the two groups (P ＞ 0.05).PaO2 was significantly lower,while Qs/Qt was significantly higher at T1,2 than at T0 in groups NS and P (P ＜ 0.05).PaO2 was significantly higher,while Qs/Qt was significantly lower at T2 than at T1 in groups NS and P (P ＜ 0.05).Qs/Qt was significantly lower at T1,2 and PaO2 was significantly higher at T2 in group P than in group NS (P ＜ 0.05).Conclusion Parecoxib 40 mg injected intravenously at 30 min before anesthesia can reduce the intrapulmonary shunt during one lung ventilation in patients undergoing esophageal cancer resection.

Endophytic fungi which reside in the tissue of mangrove plants seem to play an important role in the discovery of new biologically active substances. During the course of screening for the antimicrobial metabolites from the endophytic fugus Penicillium sp. FJ-1 of mangrove plant Avicennia marina, a new aurone glycoside (1) was isolated by repeated column chromatography on silica gel and recrystallization methods. The structure of 1 was elucidated as (Z)-7,4'-dimethoxy-6-hydroxy-aurone-4-O-β-glucopyranoside, on the basis of spectroscopic analysis. Compound 1 exhibited antifungal activity against Candida sp., with the potency comparable to amphotericin B and much better than fluconazole. Compound 1 can also inhibit extracellular phospholipase secretion in a concentration-dependent manner.

ObjectiveTo study the effects of intermittent subglottic secretion drainage(SSD)with an endotracheal tube on incidience of ventilator- associated pneumonia(VAP). MethodsWe searched computerized databases,including Cochrane library,Pubmed,EMbase,CBM,CNKI,Wanfang and some relevant databases from initializing to March 2012,extracting data about subglottic secretion drainage(SSD)with an endotracheal tube on incidence of VAP using RCT.The data had Meta- analysis by software RevMan5,and to those data which could not be conversed or merged,they underwent descriptive analysis. ResultsWeidentifled 5 randomized clinical trials that met the inclusion criteria with a total of 683 randomized patients.In Meta- analysis,the overall risk ratio for ventilator- associated pneumonia was decreased significantly by intermittent subglottic secretion drainage with an endotracheal tube.There was no significant difference on adverse events or on hospital or intensive care unit mortality.Databases,including ICU and hospital LOS,duration of endotracheal catheterization,bacteria concentration,which were difficult to be conversed and obtained full data,they underwent a descriptive research. ConclusionsCompared with the common endotracheal tubes,the use of endotracheal tubes with subglottic secretion drainage is effective for prevention of ventilatorassociated pneumonia.But it has no effect on adverse events or on hospital or intensive care unit mortality.So large sample RCTs with multiply- center should be carried out to assess the effect of the use of SSD.

Objective To explore the effects of antisense NF-?B p65 oligodeoxynucleotides on UV-induced IL-6 secretion of keratinocytes. Methods NF-?B p65 oligodeoxynucleotides were transfected to a keratinocyte cell line, HaCaT cells, mediated by lipofectamine. The NF-?B p65 protein in the cells was measured by Western blot assay, the mRNA level of NF-?B p65 was detected by RT-PCR, and UV-induced IL-6 level was determined by ELISA pre- and post-transfection and/or UVB irradiation. Results The NF-?B p65 protein expression was significantly increased in UVB (10, 20, 30 mJ/cm2 ) irradiation groups as compared with that of the control groups (P

The community - based healthcare service is a main component of healthcare service system in China,and its development is affected by several factors including correlative ethical issues.In order to maintain a long - term and stable development of community - based healthcare service,great importance should be attached to some concerned ethical issues,such as the human - oriented service,intimacy of patients,the interests of disadvantaged group,etc.

Objective To explore the inhibitory action of antisense c-jun oligodeoxynucleotides(ODN) on matrix metalloproteinase(MMP) expression of fibroblasts induced by ultraviolet B (UVB). Methods The c-jun and c-fos protein expression induced by UVB were measured by Western blot. The mRNA expression of c-jun was determined by reverse transcriptase polymerase chain reaction (RT-PCR) after transfection with c-jun antisense ODN. The pro-MMP-1 and MMP-3 synthesis of fibroblasts was measured by ELISA after treatment with UVB and antisense c-jun ODN. Results The UVB-induced c-jun protein expression of fibroblasts increased to 1.8, 2.6, 3.3 times compared with that of non-irradiated controls,while there was no significant change in c-fos protein expression. The pro-MMP-1 and MMP-3 synthesis induced by UVB irradiation increased obviously. After transfection with different concentrations of c-jun antisense ODN, the UVB-induced c-jun mRNA expression could be significantly inhibited(P

Objective To observe MSCT and clinical features in patients of laryngocarcinoma combined with other primary carcinomas. Methods Five patients of laryngeal cancer combined with multiple primary cancer were enrolled in the study. Three paitents had long-term smoking history more than 20 years. Three paitents had various degree of radiotherapy, chemotherapy and immunotherapy. The second primary cancer located in right upper lung lobe in 2 patients of synchronous cancer and 1 patient of metachronous cancer. The others located in soft palate, uvula and the left side of zone Ⅱ and zone Ⅳ in the neck, respectively. MSCT and clinical characteristics were analyzed. Results Five patients of multiple primary cancers included 2 patients of synchronous cancer and three patients of metachronous cancer. MSCT found the appearances of malignant tumors in various parts in all 5 patients and cervical lymph nodes metastasis in 2 patients. Conclusion The possibility of prime laryngocarcinoma combined with other primary cancers should be considered when other organ malignant tumor was detected in patients with laryngeal carcinoma, especially in patients with history of long-term smoking, radiotherapy and chemotherapy and immunotherapy. Long-term following-up of cervix and other organs should be taken for the postoperative patients of laryngocarcinoma.
