Objective To investigate the severity of cough in patients with different etiology of chronic cough and its related factors. Methods One hundred and fifty patients with chronic cough were recruited. The diagnosis of the patients was as follows: 24 cases with post nasal drip syndrome (PNDs), 26 cough variant asthma (CVA), 20 gastroesophageal reflux-induced cough (GERC), 31 eosinophilic bronchitis (EB), 30 atopic cough (AC) and 19 cough post infection (CPI). The severity of cough at daytime and night-time were scored by the doctor and the patient at the first visit. The correlation between cough score and age, gender and course duration of patients was analyzed. Results There was no significantly difference of cough score at daytime among different groups. Cough score at night in CVA group was significantly higher than that of other five groups (all P <0.01). Regression analysis showed that cough score at daytime was significantly correlated with age of patients (P < 0.05), while cough score at night was correlated significantly with gender (P < 0.01). Conclusion Cough severity at daytime in different etiology of chronic cough is similar, while that at night in patient with CVA is higher than that with other etiology.

Objective To explore the application of medical bottle opener box (authorized patent for utility model) in nurses dispensing operations of opening the plastic bottle cap. Methods Put five self-made medical bottle opener box sample into the hospital emergency department for use. The nurses were divided into control group and experimental group according to the different way of open bottle caps; both groups were 33 nurses who did not turn out of emergency department 2 years nurses for a common object of study. The control group was the 33 nurses adopting the method of unarmed open medicine plastic bottle cap from April 2013 to March 2014. The experimental group was the 33 nurses with medical bottle opener box to open medicine plastic bottle caps from March 2014 to March 2015. The method of comparing two groups was to compare the nurse hands skin wear parts and wear symptoms for opening bottle caps, and make the nurses′satisfaction survey. Results For two groups, the nurse hands skin wear parts were in right hand, index finger and thumb;the number of nurses with finger thick skin in experimental group was lower than that in control group [21.2%(7/33) vs. 78.8%(26/33)], and there was significant difference,χ2=21.87, P<0.05.The number of pain [12.1%(4/33) vs. 54.5%(18/33)] and peeling [15.2%(5/33) vs.69.7%(23/33)] in experimental group were lower than those in control group, and there were significant differences, χ2=13.36, 20.09, P < 0.05. The experimental group eliminated the blisters and scratches, avoided hand bleeding trauma. The nurses′overall satisfaction in experimental group was 93.9% (31/33), and 63.6% (21/33) in control group,and there was significant difference, χ2=9.06, P<0.05. Conclusions Nurses using medical bottle opener box when opening the medicine bottle cap can relieve and reduce occupational injury on the finger skin of nurses, improve the nurse hand skin comfort, provide convenient operation safety, it is worth promoting.

AIM: To explore the pathological features of airway inflammation in patients with eosinophilic bronchitis(EB) and compared to those with cough variant asthma(CVA).METHODS: Flexible fibre optic bronchoscopy was performed in 11 patients with EB,10 with CVA,14 with bronchial asthma and 10 normal controls.The mean thickness of the basement membrane was measured by light microscopy.Using immunohistochemical and special staining,the localization and density of inflammatory cells(eosinophils,mast cells,T lymphocytes) were detected in bronchial submucosa in EB and CVA patients.RESULTS: The mean thickness of the basement membrane was significantly increased in the subjects with EB [2.92 ?m(2.10-6.50 ?m)],CVA [5.64 ?m(3.23-8.48 ?m)] and bronchial asthma [9.08 ?m(6.61-11.99 ?m)] rather than that in the normal controls [2.08 ?m(1.62-3.40 ?m)].There were also significant differences among the three groups.The number of mast cells and eosinophils in the bronchial submucosal from subjects with EB [75 cells/mm~2(35-112 cells/mm~2),7 cells/mm~2(0-31(cells/mm~2))] was substantially decreased than those in subjects with CVA [148 cells/mm~2(34-200 cells/mm~2),114 cells/mm~2((1-768 cells/mm~2));P

The aim of this study is to investigate the effect of echinacoside (ECH) on cholinergic neurotransmitter extracellular of hippocampus and striatum and its possible mechanisms of neuro-protective effect against vascular dementia rats. In this study brain microdialysis technique combined with HPLC-IMER-ECD (high-performance liquid chromatography-immobilized enzyme reactor-electrochemical detector) was used. The bilateral common carotid arteries occluded in two times operation at 72 h interval for vascular dementia model rats were used and the successful vascular dementia model rats were examined by Morris water maze. The content of acetylcholine (ACh) and choline (Ch) of microdialysate extracellular of hippocampus and striatum was determined by HPLC-IMER-ECD and the AChE activity in the hippocampus was measured. The results showed that the success rate of vascular dementia model was 83.08% after six weeks; the results also showed that echinacoside and galantamine could increase the content of ACh and reduce the content of Ch extracellular of hippocampus and striatum significantly and the AChE activity increased significantly compared with that of the model group. The results suggested that echinacoside could promote the recovery of cholinergic neurotransmitter levels in vascular dementia rats' brain, which may be one of the mechanisms of neuro-protection.

China's prevention and control of parasitic diseases has made remarkable achievements. However,the prevalence and transmission of parasitic diseases is impacted by the complicated natural and social factors of environment ,natural disas-ters,population movements,and so on. Therefore,there are still the risks of the outbreak of emergency parasitic diseases af-fairs,which may affect the control effectiveness of parasitic diseases and endanger the social stability seriously. In this article , we aim at the analysis of typical cases of emergency parasitic disease affairs and their impacts on public health security in China in recently years,and we also elaborate the disposal characteristics of emergency parasitic disease affairs,and propose the estab-lishment of response system to emergency parasitic disease affairs in China,including the organizational structure and response flow path,and in addition,point out that,in the future,we should strengthen the system construction and measures of the re-sponse system to emergency parasitic disease affairs,so as to control the risk and harm of parasitic disease spread as much as possible and to realize the early intervention and proper disposal of emergency parasitic disease affairs.

OBJECTIVETo investigate the gene mutation frequencies and patterns of β-thalassemia (β-thal) in the minority populations of Guizhou province.

METHODSThree thousand and five hundred couples in the reproductive age were screened by using automatic hemocyte analyzer and hemoglobin autoanalyzer-variant. The diagnostic criteria for β-thal were: the mean corpuscular volume (MCV) was ≤ 82 fl, and the HbA(2) level was ≥ 3.5%. A total of 194 positive samples were detected and further identified by PCR-reverse dot blot (PCR-RDB) assay for 18 common β -thal mutations in Chinese population. Those subjects with positive phenotypes but without the 18 common β-thal mutations were subjected to DNA sequence analysis of the β-globin gene.

RESULTSOne hundred and eighty-nine samples with gene mutations were observed from the 3500 samples, with the incidence of β-thal being 5.4%. A total of 10 different β-thal mutations were identified from the 189 diagnosed samples. The five most common mutations were as the following: CD17 (43.9%), CD41-42 (38.6%), IVS-II-654(10.1%), -28 (2.6%) and CD71-72 (1.6%). In addition, a novel β-globin gene mutation (-CD53) allele was detected. One rare mutation of IntM was observed.

CONCLUSIONThe minority population in Guizhou province is of high risk of β-thal. It is recommended that more attention should be paid to detect the carriers of β-thal in the population in reproductive age by hematologic screening and common gene diagnosis in the area with high risk of β-thal.

Objective To study the compliance of forbidden depasturing livestock on the marshland with Oncomelania snails in schistosomiasis endemic areas. Methods According to 3 levels of human infection rates as > 10% ,5%-10% and <5% , 2 204 residents selected randomly from the schistosomiasis endemic villages were sampled with the stratified cluster sampling method in Hunan, Hubei, Jiangxi, Anhui, Jiangsu, Sichuan and Yunnan provinces, and investigated by questionnaire. The contents of the questionnaire included the recognition and implementation of forbidden depasturing livestock on marshland with Oncomelania snails and breeding livestock in bam. Results A total of 78.4% residents agreed forbidden depasturing livestock on marshland with snails, but 3. 7% residents disagreed it. A total of 83. 9% residents considered the relationship between breeding livestock in bam and schistosomiasis control, but 3. 1% residents thought that it was no relationship. The main reasons of depasturing livestock on marshland with Oncomelania snails were the high cost of breeding livestock in bam (36. 2% ) , unaccustomed (26.4% ) and no room for breeding livestock in bam (25.4% ). Conclusion Forbidden depasturing livestock on the marshland with Oncomelania snails should be strengthened according to the local economic, nature environment, agriculture, residents'culture degree and agriculture habit.

BACKGROUND: Airway stents has been widely used in airway stenosis and fistula, yet clinical date of airway stents in reestablishment a complex airway is insufficient. The aim of this study is to evaluate the efficacy and safety to combine the silicon stent and the metal stent in reestablishment a complex malignant airway. METHODS: Patients with non-operable complex malignant airway stenosis and fistula were recruited in this study. Silicon Y stent combined with covered metal stent (Hybrid stent) were inserted to reestablishment the airway. Clinical outcomes and complications were observed over six months. RESULTS: A total of 23 silicon Y stents and 25 covered metal stents were inserted in 23 patients. Nineteen of 23 (19/23, 82.6%) patients felt a immediately relieving of current symptoms. The mean duration of stents placement in patients was (153.43±9.14) days. The modified British Medical Research Council, Karnofsky Performance Status and Performance Status scale were improved significantly after stenting. A total of 12 patients living with stent at 6 months. Others dead of tumor progression. There were no death or immediate complications related to hybrid stenting implication. CONCLUSIONS Hybrid stenting proved to be useful and was well-tolerated in the management of complex malignant airway stenosis and fistula.
