Objective To assess the effect of thoracoscopic surgery under laryngeal mask anesthesia and explore the nursing strategies. Methods Thirty-five patients from April to December in 2014 undergoing video-assisted thoracoscopic surgery (VATS) were given intubation anesthesia and another thirty-five ones undergoing the same surgery in 2015 received laryngeal mask anesthesia. The two groups were compared in terms of surgery conditions, surgery complication and ambulation time. Results No significant differences were found in surgery time or blood loss between two groups (P>0.05). The postoperative waking time in the mask anesthesia group was significantly shorter than that of the intubation anesthesia group (P<0.05), and ambulation time was significantly shortened (P<0.05). The rates of throat discomfort, hoarseness and gastrointestinal reactions were significantly lower. Conclusions Laryngeal mask anesthesia used in small thoracoscopic surgery for airway management is safe and feasible. Combined with training in respiration and limb function, better analgesia and nursing, it can keep away complications related to intubation anesthesia, shorten hospital stay and accelerate postoperative rehabilitation.

The effect of siRNA-mediated Sox4 gene silencing on Wnt/β-catenin signaling pathway of human malignant melanoma cell line A375 was investigated. Two types of dsRNA targeting Sox4 were constructed and transfected into A375 cells, and untreated cells and cells transfected with scramble RNA were used as blank control and negative control respectively. The expression levels of mRNA and protein of Sox4, Wnt3a, β-catenin and Wnt/β-catenin signaling target gene Survivin were detected after real-time PCR and Western blot respectively. MTT assay was used to measure cell proliferation after Sox4 knockdown. β-catenin/TCF transcription reporter assay was used for assessing Wnt/β-catenin signaling pathway activity. Our results showed that the two types of Sox4 siRNA were transfected into A375 cells successfully. As compared with untreated cells, Sox4 siRNAs had no significant influence on Wnt3a expression, and Sox4 siRNAs led to the decrease of β-catenin at protein level. Wnt/β-catenin signaling pathway activity was inhibited significantly. As a target of Wnt/β-catenin signaling, Survivin was decreased at both mRNA and protein levels, and cell proliferation was attenuated. Our study suggests that Sox4 may play an important role in Wnt/β-catenin signaling pathway in human malignant melanoma cells by regulating β-catenin protein level, indicating that Sox4 is involved in the progression of malignant melanoma through Wnt/β-catenin signaling pathway.

Objective To study the feasibility and effect of implantation of the biliary stent for treatment of biliary obstruction.Methods A retrospective analysis of the diagnostic and therapeutic procedure was done in 131 cases of the inpatients from Apr.2006 to Feb.2007.The 131 patients with biliary obstruction underwent successfully 138 cases/times implantation of biliary stent.The results of recession of jaudince and the rate of complication were evaluated.Results All patients were implanted biliary stent successfully.The serum total bilirubin,direct bilirubin,alkaline phosphatase,?-glutamyl transpeptidase decreased obviously in three days,and the difference was remarkable.The main complication was infection of biliary tract and pancreatitis.Conclusion Implantation of biliary stent is an effective management for biliary obstruction,especially for patients who have lost the chance of operation.

Objective To explore the clinical features of renal and urinary lesions in IgG4-related disease (IgG4-RD).Methods Clinical manifestation,laboratory profiles,iconography images,pathologic findings,treatment and prognosis of 6 IgG4-RD patients with renal and urinary system involvement from Peking Union Medical College Hospital during Aug 2010 to Dec 2011 were analyzed retrospectively.Results Six patients had renal and/or urinary lesions among IgG4-RD cases diagnosed in our hospital,including 4 males and 2 women,with median age of 59 years (36 to 72 years) and median disease course of 10.5 months.All the patients presented multiple organ involvement simultaneously.Urinary system lesion varied,including renal dysfunction,abdominal pain and edema.Hyperglobulinemia,elevated serum IgG (median 23.3 g/L) and IgG4 (median 4227.0 mg/L),tubular proteinuria were found in all the 6 patients,and elevated Scr (median 237 μmol/L) in 5 cases.Kidney CT image often showed renal swelling,hydronephrosis,multiple low density focus with attenuation and kidney atrophy.Renal pathology revealed interstitial inflammatory cells infiltration comprising predominantly plasma cells and lymphocytes,with a high prevalence of IgG4-positive cells often admixed with fibrosis,which fit the features of tubulointerstitial nephritis.Patients with IgG4-RD nephropathy presented good response to glucocorticoids.After therapy,the symptoms were improved and serum IgG,IgG4 and Scr decreased.Conclusions Renal and urinary lesions of IgG4-RD are heterogeneous in clinical manifestation,and are often complicated with various organ lesions.The feature of renal histopathology is tubulointerstitial nephritis infiltrated by plasma cells and lymphocytes with positive IgG4.Glucocorticoids treatment is effective for this disease.

OBJECTIVE:To develop a detection LC-MS/MS method for global DNA methylation in medicinal plants. METH-ODS:Genomic DNA was isolated using plant DNA extraction kit,and then hydrolyzed by 88% formic acid at 140 ℃. After dried with nitrogen,extracted DNA was dissolved again with mobile phase. LC separation was performed on HILIC column with mobile phase consisted of 7 mmol/L ammonium formate-acetonitrile (gradient elution) at flow rate of 0.3 ml/min. The analysis was con-ducted by tandem MS with positive ion electrospray ionization in multiple reaction monitoring(MRM)mode. The ratio of genomic DNA methylation in 10 commonly used medicinal plants was calculated. RESULTS:The linear ranges of Cyt and 5mC were 1-500 ng/ml(r=0.999 5)and 0.2-100 ng/ml(r=0.999 6). The relative standard deviations(RSDs)of accuracy were 1.12% and 3.68%(n=6). The RSDs of intra-day precision were 2.36% and 4.02% for Cyt and 5mC,respectively (n=5). The RSDs of inter-day precision were 1.04% and 3.54% for Cyt and 5mC,respectively (n=3). The RSDs of repeatability test were 1.53% and 3.27%for Cyt and 5mC,respectively(n=6). The recoveries of Cyt and 5mC were 98.7%-102.1% and 91.2%-103.5%. The percentages of global DNA methylation in 10 medicinal plants were ranged from 17.63% to 25.18%. CONCLUSIONS:LC-MS/MS method is simple,rapid,sensitive and precise,and can be used for the detection of global DNA methylation in medicinal plants.

Objective To investigate the diagnostic value of coding gene of Sj26, Sj32 and Sj14-3-3 amplified by PCR for chronic Schistosomiasis japonica. Methods The DNA was extracted from sera of 40 patients with chronic Schistosomiasis japonica, the coding gene of Sj26, Sj32 and Sj14-3-3 was amplified by PCR and identified by 1.2% agarose gel electrophoresis. DNA from the sera of 21 patients with Clonorchiasis sinensis, 13 patients with Parogonimiasis westermani and 43 healthy donors was taken as control. Results A total of 399 bp coding gene of Sj14-3-3 was amplified successfully from sera of the patients with chronic Schistosomiasis japonica,but Sj26(676 bp) and Sj32( 1270 bp) coding gene were not obtained. Control groups were all negative. Conclusions Sj14-3-3 coding gene amplified by PCR can be used for genetic diagnosis of chronic schistosomiasis.
