Objective To verify the association of a disintegrin and metalloproteinase domain 33 (ADAM33) polymorphisms in childhood asthma susceptibility and severity in patients with moderate and severe asthma.Methods A total of 144 controls and 110 asthmatic patients were recruited for this hospitalbased case-control study.Two polymorphic sites (V4,T2) were genotyped using the polymerase chain reaction-restriction fragment length polymorphism method.The gene-gene interactions were analyzed with the multifactor dimensionality reduction (MDR) software.Results The allele frequencies of three SNPs (V4,T2) of ADAM33 in childhood asthma group were significantly higher than control group (P ＜ 0.01,OR =2.36 ～ 2.96,95％ CI:1.56-1.78 ～ 3.56-4.94).For the SNPs V4,GC genotype frequencies of both moderate and severe groups were significantly higher from the control group (P ＜ 0.05) ; the CC genotype frequencies in severe group were significantly higher than control group (P ＜ 0.05) ; the genotype GA of T2 locus in severe group and AA genotype frequencies in moderate group were significantly higher than control group (P ＜0.01 ～0.05) ; there were no significant differences for both allele and genotype frequencies of S2 locus between the childhood asthma and control group (P ＞ 0.05).By MDR analysis,the best interaction model was the four-factor model that the V4,T2 genotypes were the subgroup to predict asthma risk.Conclusions Our results highlight the role of ADAM33 as a susceptibility gene for childhood asthma,and the interactions among ADAM33 V4 and T2 are also associated with childhood asthma.

Objective: To understand the situation of school health staff and the allocation of health equipment in primary and secondary schools in Jinan. Methods: A questionnaire survey was conducted in CDC and public primary and secondary schools to describe the situation of the school health staff and health equipment in primary and secondary schools. Results: There were 23 school health staffs in CDC, among which 26.1% were full time. The total staffing ratio of school doctors was 13.9%, with the compliance rate of 19.8%. The total allocation rate of health care teachers was 74.7%, 92.2% of them were part time. The total staffing ratio of school doctors in boarding schools was 20.0%, with a staffing compliance rate of 12.5%. The total allocation rate of school doctors and health care teachers in boarding schools was 66.7%. 16.8% of public primary and secondary schools and 23.3% of public boarding primary and secondary schools did not have any health staffs. 27.6% of public primary and secondary schools are equipped with infirmary, 70.8% with health rooms, and 10.3% without any. The configuration of necessary equipment in infirmary and health care rooms were less than 100%. Conclusion There is a serious shortage of school health staffs and health equipment in primary and secondary schools in Jinan. Attention and investment in school health should be strengthened, and resources should be rationally allocated to ensure the health of primary and secondary school students.

Objective To evaluate the safety and efficacy of transurethral frontfiring photoselective vaporesection for the treatment of cystitis glandularis,by comparing with the transurethral bipolar plasmakinetic resection.Methods From January 2014 to July 2016,41 patients with pathologically diagnosed cystitis glandularis in our hospital,were divided into two groups,including 22 cases underwent transurethral frontfiring photoselective vaporesection(the observation group),and the other 19 cases underwent transurethral bipolar plasmakinetic resection(the control group).All patients were regularly treated with postoperative intravesical instillation chemotherapy with pirarubicin.The clinical data of two groups were statistically analyzed to compare the differences of the safety and efficacy.Results All the surgeries were performed successfully.There were no statistical significances in perioperative data,the operation time,the decreased concentration of hemoglobin(Hb)and Na+,operative related complications, indwelling catheter duration and hospitalization duration between the two groups.The first-time cure rate and the effective rate of transurethral frontfiring photoselective vaporesection showed significantly better than those of transurethral bipolar plasmakinetic resection(P<0.05 for each).Conclusion Comparing the traditional transurethral bipolar plasmakinetic resection for the treatment of cystitis glandularis,tansurethral frontfiring photoselective vaporesection with postoperative intravesical instillation chemotherapy with pirarubicin,is a safer,simpler,and more effective method,which could be a new optional method in the conditional hospitals,deserving the worthy of clinical popularization.

Objective:To evaluate the clinical effect of integrated traditional Chinese and Western medicine on common type of coronavirus disease 2019 (COVID -19) in Henan Province. Methods:A prospective single arm clinical study was performed. Patients with common type of COVID -19 admitted to seven designated hospitals for COVID -19 in Henan Province from January 25th to February 26th, 2020 were enrolled, and treated with integrated traditional Chinese and Western medicine. The negative transformation of 2019 novel coronavirus (2019 -nCoV) nucleic acid, disease outcome, hospital stay, clinical symptoms and signs scores, and chest imaging performance were observed. Results:Totally 86 cases were included in the analysis, including 48 males (55.8%), aged 43.5 (35.0, 53.3) years old, 24 patients (27.9%) with previous medical history. Fifty-eight patients were primarily diagnosed COVID -19 and 28 patients were transferred. The 2019 -nCoV nucleic acid of 86 cases (100%) turned negative, and the median time of turning negative was 10 (7, 14) days. Eighty-six cases (100%) were discharged from hospital, and none turned into the severe type; the average length of hospital stay was (13.8±5.6) days. The scores of fever, cough, chest tightness, shortness of breath, and fatigue decreased with the treatment time, and the scores of 7 days and 14 days after treatment were significantly lower than those before treatment [fever (points): 0 (0, 0), 0 (0, 0) vs. 1 (0, 1); cough (points): 1 (0, 1), 0 (0, 1) vs. 1 (0, 2); chest tightness (points): 0 (0, 0), 0 (0, 0) vs. 0 (0, 1); shortness of breath (points): 0 (0, 0), 0 (0, 0) vs. 0 (0, 1); fatigue (points): 0 (0, 1), 0 (0, 1) vs. 1 (0, 1); all P < 0.05]. The improvement rate of X ray and CT image was 42.9% (12/28) and 81.0% (64/79), respectively. Conclusions:The treatment with integrated traditional Chinese and Western medicine has good curative effect on common type of COVID -19 in 7 designated hospitals of Henan Province. It can improve the clinical symptoms, promote the absorption of pulmonary inflammation, and to some extent control the progress of disease and shorten the time of turning negative of virus nucleic acid and hospital stay.
