Objective To study the mechanism of NS1619 on airway remodeling in asthmatic mice. Methods A total of 24 healthy female BALB/c mice were randomly divided into 3 groups:the control group, the oval albumin (OVA) group (the asthma group) and the NS1619 group (the intervention group), 8 mice in each group. Asthma group was induced with OVA, chal-lenged by continuous inhalation with 5%OVA from day 19 to 23, then changed to 3 times per week from day 24 to 55. Interven-tion group was inhaled with NS1619 (30μmol/L) before OVA. Control group was given with normal saline. The thickness of air-way smooth muscle and the area of collagen deposition in lung tissue slices were observed by HE and Masson staining, measured by a computer assisted image analysis system. The concentration ofα-smooth muscle actin (α-SMA) in cells was detected by immunohistochemistry. The expression of platelet derived grouth factor-BB, PDGF-BB (PDGF-BB) in serum was measured by immunosorbent assay. Results Compared with the asthma group, the pathologic changes of lung tissue, the thickness of airway smooth muscle and collagen deposition in the group treated with NS1619 were signiifcantly decreased (P<0.05). Compared with the asthma group, the levels ofα-SMA in cells and PDGF-BB in serum in NS1619 treated group were signiifcantly decreased (P<0.05). Conclusions NS1619 partly inhibited airway remodeling in asthmatic mice, partially by down-regulating the expres-sion level ofα-SMA and PDGF-BB.

OBJECTIVE:To study the relieving cough and eliminating phlegm effects of stemoninine combined with mogrosideⅤ on mice,and select its optimal ratio. METHODS:70 mice were selected in each experiment and randomly divided into 7 groups,namely solvent group(normal saline), codeine(15 mg/kg)or ambroxol(30 mg/kg)group(positive control),stemoni-nine group(30 mg/kg),mogroside Ⅴ group(30 mg/kg),stemoninine-mogroside Ⅴ combination group(30 mg/kg)with mass ra-tio of 2:1,1:1,1:2,ig,once a day. Ammonia-induced cough experiment(positive drug was codeine)and tracheal phenol red ex-cretion experiment(positive drug was ambroxol)were respectively conducted. Using cough latent period,cough times and volume of tracheal phenol red excretion as indexes,the antitussive and expectorant effects of drug in each group were compared. RE-SULTS:Compared with solvent group,cough latent period was obviously shortened,cough times was obviously reduced,volume of tracheal phenol red excretion was obviously increased in each administration group(P<0.05 or P<0.01). Compared with mogro-side Ⅴ group,cough latent period was obviously shortened,cough times was obviously reduced in stemoninine-mogroside Ⅴgroup with different mass ratios(P<0.05),and 2:1,1:1 groups showed the best effects. Compared with stemoninine group,vol-ume of tracheal phenol red excretion was obviously increased in stemoninine-mogroside Ⅴ group with different mass ratios (P<0.05),and 1:1,1:2 groups showed the best effects. CONCLUSIONS:The combination of temoninine and mogroside Ⅴ shows synergistic effects on relieving cough and eliminating phlegm,stemoninine-mogrosideⅤmass ratio of 2:1,1:1 can be used as pre-ferred combination of reference.

OBJECTIVE To explore the reasons of high wet package rate of the rent surgical instrument and to look for improvement method.METHODS A total of 2872 packages of hospitals in Chongqing city were investigated during the last two years.RESULTS Among 2872 rent surgical instrument packages,1064 packages were found to be damp(37.05%).CONCLUSIONS Unstandardized and too large packaging are the main reasons.After elimination of above two reasons,the damp rate will be decreased.

Objective To explore different socio-demographic and clinical characteristics for early onset patients (EOP) with psoriasis and late onset patients (LOP) with psoriasis in Chinese population and to provide scientific evidences for establishing comprehensive prevention and treatment strategy for psoriasis.Methods Cross-sectional study was performed.A total of 942 diagnosed psoriasis patients who paid a visit to outpatient clinic in a tertiary hospital in China from 12th September 2013 to 19th May 2015 was consecutively enrolled and investigated.Exploratory analysis was conducted to detect the association between disease onset age and patients features.Results Among 942 enrolled psoriasis outpatients,the average age was (40.6 ± 13.6) years with a range from 5 to 80 years.The sex ratio was 2.1 in favor of male.The most observed type of psoriasis in the present study was psoriasis vulgaris (98.3％).The average psoriasis area and severity index (PASI) for patients were 9.47 ±7.63.Comorbidity was combined in 20.2％ cases.Patients with EOP had a significantly higher likelihood of family history of disease.Compared EOP to LOP,LOP had a significantly higher likelihood of comorbidities involvement (P ＜ 0.05) and significant higher BMI index (P ＜ 0.05).Conclusions The present study supports the hypothesis that there are clinical differences between EOP and LOP in Chinese population.Both dermatologists and patients should pay more attention to psoriasis-associated features,such as family history and comorbidity diseases involvements.

OBJECTIVE: To explore the methods of the larygeal recurrent nerve dissection in different and difficult thyroid surgery, so as to minimize damage and improve the safety of the operation. METHOD: The process and methods in different laryngeal recurrent nerve dissection about 52 hospitalized patients from 2010 to 2012 were retrospectively analyzed. These cases include large nodular goiter, nodular goiter behind the sternum or located in the lower pole of the thyroid gland, thyroid cancer, tumors of parathyroid gland, etc. We studied the conditions of lesions involving the laryngeal recurrent nerve and the defensive measures to protect the nerve. RESULT: The laryngeal recurrent nerve was dissected successfully in 50 cases, except 2 cases whose laryngeal recurrent nerve were violated by thyroid cancer. CONCLUSION When we dissect the laryngeal recurrent nerves in different and difficult thyroid, the glands and tumors were mostly needed to be freed and turned inward and forward. After that, the laryngeal recurrent nerves can be dissected successfully with the markers of tracheoesophageal groove, inferior thyroid artery and/or angle under the thyroid cartilage.

Objective To investigate the relationship between cognitive function and emotional status in functional constipation patients.Methods Thirty-five functional constipation patients (the functional constipation group) and 24 healthy controls (the HCs) were enrolled in an event-related potential (ERP),behavior and electroeneephalogram study while performing an oddball auditory task.Response time,accuracy,latency and P300 amplitude were compared between the two groups.The Hamilton depression rating scale (HAMD-17),Hamilton anxiety scale (HAMA),symptom check list-90 (SCL-90) and Eysenck personality questionnaire (EPQ) were administered prior to the oddball task.Results The average HAMD-17,HAM A and SCL-90 (the somatization,obsessive-compulsive disorder,depression,anxiety and psychosis dimensions) scores of the functional constipation group differed significantly from those of the HCs.The intro-extraversion and neurosis dimensions of the EPQ were also significantly different.There was no significant difference in response time or latency between the two groups.The ERP results showed that the P300 amplitudes at the F3 and F7 sites were significantly different between the functional constipation group and the HCs.But there was no significant difference in P300 latencies at F3 or F7 between the two groups.Conclusions The findings suggest that patients with functional constipation are more susceptible to depression and anxiety,as well as somatization,obsessive-compulsive tendencies and other neurotic personality characteristics.Patients may employ psychological defense mechanisms to avoid the depression and anxiety.The ERP results imply there may be the implicit cognitive dysfunction with emotion in patients with functional constipation.

Objective:To detect the correlativity between clinical periodental indexes and C-terminal telopeptides of type I collagen (CTX)concentration in gingival crevicular fluid(GCF).Methods:77 teeth with periodontitis in 60 patients from the international Bethune peace hospital were included.The concentration of CTX in GCF was detected by enzyme-linked immunosorbent assay.The plague indexe(PL),gingival indexe(GI),probing depth(PD)and attachment loss (AL)level were recorded at clinic.The correla-tion of CTX concentration and clinic indexes was analysed by Kruskal-Wallis test using SPSS 1 1 .0 software.Results:The Spearman correlation coefficient of PL,GI,PD and AL with CTX was 0.386(P <0.01 ),0.366(P <0.05),0.382(P <0.05)and 0.31 4(P <0.05)respectively.Conclusion:PL,GI,PD and AL are positively correlated with the concentration of CTX in GCF(P <0.05).

Objective To investigate the epidemiology of drug-resistant tuberculosis (TB) in five rural counties of eastern China and analyze the biological,demographic and social risk factors.Methods Subjects of this study were all the diagnosed TB patients registered in the five study sites in Shandong Province,Jiangsu Province and Zhejiang Province during one year of 2008- 2009.Questionnaire interview was conducted in all the subjects to acquire the socio-demographic and clinical information.Sputum samples were collected for culturing and isolating of Mycobacterium tuberculosis (M.TB) strains.All the M.TB isolates were further tested for the susceptibility to first-line drugs including rifampin,isoniazid,ethambutol and strepomycin by proportion method.Mantel-Haenszel chi-square test,Fisher's exact test,ANOVA and nonconditional Logistic regression modeling were applied for data analysis.Results Among the total 380 M.TB isolates,105 were resistant to at least one of the first-line drugs.The total drug resistant TB prevalence was 27.6％.Multidrug-resistant tuberculosis (MDR-TB) was observed in 8.4％ of newly treated TB patients,whereas it was 23.3％in previously treated TB patients.After adjusted by county,gender and age of the subjects,multivariate analysis showed that previous treatment history (OR=3.900,95％CI: 1.737-8.704),tuberculosis cavity (OR - 1.987,95 ％ CI: 1.001 - 3.942) were independent factors influencing the occurrence of MDR-TB.Conclusions The prevalence of drug resistant TB in rural area of eastern China is relatively low compared with the average level in China,while it is still higher than the global average level.The present study highlights that TB patients with previous treatment history,cavitaryTB are correlated with MDR-TB,and elderly patients are at high risk of MDR-TB.
