Objective To investigate manifestations of chronic obstructive parotitis (COP) under sialoendoscope and to evaluate curative effects of duct dilatation and drug perfusion for COP. Methods Twelve patients with COP were examined by sialoendoscopy. Treatment was performed by duct dilatation and gentamycin perfusion one week later. Results There were 11 cases of sialodochitis (complicated by sialostenosis in 7 cases, including 4 cases of polyps and 2 cases of mucus embolism, and simple sialodochitis in 4 cases) and 1 case of simple sialostenosis. Follow-up for 4 weeks showed that results were excellent in 4 cases, good in 7 cases, and poor in 1 case. Conclusions Sialoendoscopic exploration with dilatation procedure and drug perfusion offers certain short-term curative effects in the management of COP.

Objective To establish the RP-HPLC method for determination of Bruchine and Strychine in Pingxiao Tablet. Methods The lichrospher C18 (4.6 mm?250 mm, 5 ?m) was Used as the stationary phase. The Mobile phase consisted of water-acetonitrile (60∶40) with 1.7 g sodium dodecylsulphate and 3.4 g KH2PO4 in 1 000 mL mixture. The Detecting wavelength was 254 nm and flow rate was 1.0 mL/min. The column temperature was 25 ℃. Result The linear ranage of Bruchine and Strychine were 0.102～0.918 ?g and 0.208 ～ 1.872 ?g respectively. The recovery rates of bruchine and strychnine were 101.07% (RSD=2.26%) and 99.29% (RSD=2.79%) respectively. Conclusion This method is realiable and accurate, the method can be applied to determination the contents of Bruchine and Strychine in Pingxiao Tablet.

Objective To reduce the rate of unscheduled nasogastric extubation for the patients in neurology department.Methods A nursing care team was set up for a thematic activity to reduce the rate of nasogastric tube unscheduled extubation.The team analysed the situations of 164 patients with nasogastric intubation in the neurology department,specifying the problems,deciding their aims and working out the strategies.Result The rate of unscheduled nasogastric extubation decreased from 19.63％ to 2.12％ and the rate of nursing omission decreased from 9.93％ to 2.59％ (P＜0.05).Conclusion The improvement activity of nursing projects can effectively reduce the rate of unscheduled nasogastric extubation and improve the quality of nursing care.

Objective To find out the weakness in the emergency nursing for burst group accidents, and then building a normative nursing program which have included framework and 4 stages. Methods Using the method of Fish-Bone Drawing to analyzed the nursing courses in 22 burst accidents within the past 4 years retrospectively. Results After using the normative nursing program, nurses have known their own working targets and responsibility, which can apply the nursing care effectively and orderly. Conclusion The application of emergency nursing program is a kind of quick and proper nursing method, which can improve the patients' prognosis effectively.

The process mechanism and current application status of boron removal in reverse osmosis(RO)desalination were introduced.The characteristic and proper application range of eachboron removal process was summarized.Also,the running conditions of two practical desalination cases were analyzed and compared.Eventually,the future of application and the research direction of boron removal process in RO desalination were prospected.

Leukotriene B₄ (LTB₄) is a proinflammatory lipid mediator that is synthesized by a number of inflammatory cells. Binding of LTB₄ to its receptor leukotriene B₄ receptor 1 (BLT1) can migrate neutrophils and macrophages to inflammatory sites through chemotaxis and up-regulation of adhesion molecules. Many researches have shown that LTB₄-BLT1 axis is related to the occurrence of autoimmune disorders and other inflammatory diseases. Receptor antagonists of LTB₄ are thus expected to be useful therapeutics for these diseases. In this review, we briefly describe the biological function of LTB₄ and summarize the preclinical and clinical developments of LTB₄ receptor antagonists.

Objective To study the association between house dust endotoxin levels and the airway responsiveness as well as allergen sensitization in adolescence in the urban and rural areas of Guangdong province.Methods Middle school students,aged 13-14,188 (male 109,female 79) from Guangzhou,129(male 70,female 59) from Conghua with positive responses,and 231 (male 125,female 106) and 307(male 145,female 162) of their respective reference students are selected from questionnaire prescreening.A detailed questionnaire,the lung function test,histamine bronchial provocation test,skin prick test and peripheral blood eosinophil count are undertaken.Seventy-six students from Guangzhou and 80 from Conghua were selected randomly for mattress dust sample collection to detect the levels of endotoxin.Results The prevalence of wheeze symptom,diagnosed asthma,nasal symptoms and allergic rhinitis of Guangzhou was significantly higher than that of Conghua (P＜0.0001),with 28.6％,27.7％,66.0％,46.4％ for Guangzhou respectively,and 5.0％,2.5％,31.0％,6.2％ for Conghua respectively.The positive rates of bronchial provocation test and skin sensitization against Dermatophagoides pteronyssinus(Der.p),D.farinae (Der.f),cat and dog allergen in the students of Guangzhou were significantly higher than that of Conghua (P＜0.0001).The positive rate of cockroach of Conghua was significantly higher than that of Guangzhou (P＜0.0001).The levels of endotoxin (amount,concentration and load) of samples from Conghua were significantly higher than that from Guangzhou (Conghua:6452 EU,10.95 EU/mg,1794 EU/m2 ;Guangzhou:1591 EU,6.45 EU/mg,508.80 EU/m2,respectively).PD20-FEV1 was correlated positively with endotoxin amount(r=0.174,P＜0.05).The diameters of the skin wheal size for Der.p and Der.f were correlated inversely with endotoxin amount and load (P＜0.001).Conclusion The prevalence of wheeze symptom,diagnosed asthma,nasal symptoms and allergic rhinitis in 13-14 year-old adolescent of Guangzhou was significantly higher than that of Conghua.Cockroach was the second major allergen of Conghua followed by house dust mite.The level of endotoxin was correlated positively with PD20-FEV1,but correlated inversely with skin sensitization to Def.p and Der.f.The study suggests that environmental endotoxin may have effect to protect children from developing allergic diseases.

Currently,three predominant subtypes of influenza virus are prevalent in pig populations worldwide:H1N1,H3N2,and H1N2.European avian-like H1N1 viruses,which were initially detected in European pig populations in 1979,have been circulating in pigs in eastern China since 2007.In this study,six influenza A viruses were isolated from 60 swine lung samples collected from January to April 2011 in eastern China.Based on whole genome sequencing,molecular characteristics of two isolates were determined.Phylogenetic analysis showed the eight genes of the two isolates were closely related to those of the avian-like H1N1 viruses circulating in pig populations,especially similar to those found in China.Four potential glycosylation sites were observed at positions 13,26,198,277 in the HA1 proteins of the two isolates.Due to the presence of a stop codon at codon 12,the isolates contained truncated PB1-F2 proteins.In this study,the isolates contained 591Q,627E and 701N in the polymerase subunit PB2,which had been shown to be determinants of virulence and host adaptation.The isolates also had a D rather than E at position 92 of the NS1,a marker of mammalian adaptation.Both isolates contained the GPKV motif at the PDZ ligand domain of the 3' end of the NS1,a characteristic marker of the European avian-like swine viruses since about 1999,which is distinct from those of avian,human and classical swine viruses.The M2 proteins of the isolates have the mutation (S31N),a characteristic marker of the European avian-like swine viruses since about 1987,which may confer resistance to amantadine and rimantadine antivirals.Our findings further emphasize the importance of surveillance on the genetic diversity of influenza A viruses in pigs,and raise more concerns about the occurrence of cross-species transmission events.
