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 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 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 examine the clinical factors associated with postoperative outcome in dementia combined with cerebral amyloid angiopathy-related intracerebral hemorrhage (CAA-ICH). Methods The clinical data of 25 surgical patients of dementia combined with CAA-ICH were retrospectively analyzed. The postoperative short-term effects and long-term effects were evaluated at the 30 d and 6 months after operation according to the modified Rankin score (MRS), and the influencing factors were analyzed. Results Among the 25 patients, eusemia was in 6 cases. Age ≥ 75 years, Glasgow coma score (GCS) ≤ 8 scores on admission, hypertension, postoperative anemia, pulmonary diseases, midline shift were the influencing factors of postoperative short-term effects (P < 0.05 or <0.01). Twenty-two patients were followed up for 6 months, and ensemia was in 9 cases. Age≥75 years, GCS ≤ 8 scores on admission, hypertension, postoperative anemia, hypoproteinemia and pulmonary diseases were the influencing factors of postoperative long-term effects (P<0.01 or<0.05). Conclusions Preoperative assessment is important for the patients of dementia combined with CAA-ICH. Age ≥ 75 years, GCS ≤ 8 socres on admission, hypertension, postoperative anemia, pulmonary diseases, midline shift are associated with poor short-term effects; age ≥ 75 years, GCS ≤ 8 scores on admission,hypertension, postoperative anemia, hypoproteinemia and pulmonary diseases are associated with poor long-term effects.

Objective To investigate the effects of the intellegent CO2 laser assisted Fisch stapedotomy with artificial stape prostheses in the treatment of otosclerosis.Methods A total of 28 patients with otosclerosis who had undergone the intellegent CO2 laser assisted Fisch stapedotomy with artificial stape prostheses were retrospectively e-valuated.The intellegent CO2 lasersare was used to vaporize stapedius tendon,posterior crus of stapes,and most importantly perforate stapes footplate.Bone and air conduction thresholds were determined at 0 .5 ,1 ,2 ,and 4 kHz preoperatively and 6 months postoperatively in all patients.Results No sustained vertigo or sensorineural hearing loss occurred postoperatively.There were no statistically significant differences between preoperative and postopera-tive average bone conduction thresholds.Preoperative and postoperative air bone gap were 30.38(23.13,39.38)dB HL,9.75(8.25,10)dB respectively and the postoperative results were significantly different from the preopera-tive.Conclusion The intellegent CO2 laser can be used safely in stapes footplate surgery and is well suited for trea-ting otosclerosis.

Objective To assess the value of combined detection of enterovirus nucleic acid and antibody in early etiological diagnosis for hand-foot-and-mouth disease ( HFMD).Methods A case-control study was conducted.A total of 1 066 cases of children clinically diagnosed with HFMD from Hangzhou Children′s Hospital were involved into the research group from January to June 2014, consisting of 401 common cases and 665 severe cases; Throat swabs and serum samples from these children underwent combined detection for EV71/CA16/EV of enterovirus nucleic acid by fluorescence quantitative RT-PCR and for EV71/CA16-IgM by ELISA.All data were analyzed with SPSS 16.0.Results The total positive rate of enterovirus nucleic acid EV71/CA16/EV by fluorescence quantitative RT-PCR in the 1 066 cases of children clinically diagnosed with HFMD was 75.52%( 805/1 066 ) ( 95%CI: 72.80%-78.05%).But the total positive rate of combined detection was 91.46%( 975/1 066 ) ( 95%CI:89%.58-93.04%).The total positive rate of combined detection is higher than that of RT-PCR test(χ2 =98.338,P=0.000).The positive rate of EV71 type of combined detection was 64.63%(689/1 066)(95%CI:61.67%-67.49%),which is 15.38%higher than that of RT-PCR test 49.25%(525/1 066)(95%CI:46.21%-52.29%)(χ2 =51.453, P=0.000).In 665 severe cases of HFMD, the total positive rate of combined detection was 96.69%(643/665)(95%CI:94.95%-97.87%), which is higher than that of RT-PCR test 79.25%(527/665)(95%CI:75.92%-82.22%)(χ2 =95.607, P =0.000).In the severe cases, the positive rate of EV71 type of combined detection was 87.52%( 582/665 ) ( 95%CI:84.71%-89.89%) , which is 18.95% higher than that of RT-PCR test 68.57%(456/665) (95%CI:64.87%-72.06%) (χ2 =69.665, P=0.000).In the fatal cases, the positive rate of EV71 type of combined detection was 95.92%(94/98) (95%CI:89.28%-98.68%).Conclusions The combined detection of enterovirus nucleic acid and specific IgM antibody can significantly increase the positive rate of HFMD, especially for severe cases.The combine detection increases both the total positive rate and EV71 positive rate.Thus it has a high potential for becoming a new guidelines for laboratory diagnosis of HFMD.
