Objective:To analyze the death rate of asthma among Chinese people aged 0-19 years in 2018 and the trend of asthma mortality between 2008 and 2018, in order to guide the research of asthma control management and prevention strategy, and reduce the mortality of childhood asthma in China.Methods:Data from the national disease surveillance points system (DSPs) was adopted.The mortality rates of 0-19-year-old people in different age groups, genders, places of residence and geographical regions from 2008 to 2018 were calculated, and the national death toll of asthma was estimated as well.The annual percentage change (APC) and average annual percentage change (AAPC) were calculated, and the death rate of asthma among Chinese people aged 0-19 years in 2018 and change trend of asthma mortality from 2008 to 2018 were analyzed.Results:In 2018, there was no significant gender diffe-rence in asthma mortality among Chinese people aged 0-19 years among different age groups, places of residence and geographical regions(all P>0.05). From 2008 to 2018, the mortality rate of people aged 0-19 fluctuated from 0.023/100 000 to 0.046/100 000, the highest mortality rate was in 2009 and 2012, and the lowest was in 2018. It was estimated that the total number of deaths among people aged 0-19 years reached the highest in 2009 (148 cases) and the lowest in 2018 (70 cases). It is estimated that the total number of deaths among people aged 0-19 years in China from 2008 to 2018 was 1 158 cases.From 2008 to 2018, the total mortality rate of asthma in Chinese population aged 0-19 years decreased significantly (AAPC=-7.6%, 95% CI: -10.4%--4.7%). There was a significant decrease in male group(AAPC=-7.4%, 95% CI: -12.5%--2.0%), female group(AAPC=-7.5%, 95% CI: -12.7%--2.0%), 1-<5 years old group(AAPC=-11.4%, 95% CI: -17.9%--4.5%), 15-19 years old group(AAPC=-14.4%, 95% CI: -24.8%--2.6%), rural group(AAPC=-9.0%, 95% CI: -13.1%--4.8%) and central areas(AAPC=-13.1%, 95% CI: -24.0%--0.5%), with statistical significance(all P<0.05). Conclusions:The total mortality of asthma in 0-19-year old population decreased significantly from 2008 to 2018.The mortality rate of asthma in 0-19-year old people in China is at the low level around the world.

Objective To study the effect of Tongxinluo on the plasma C-reactive protein(CRP)and endothelin-1(ET-1)in acute coronary syndrome(ACS) patients.Methods 100 patients with ACS were randomly divided into conventional therapy group and treatment group(conventional therapy+Tongxinluo gelatin capsule).The changes of CRP and ET-1 in the first day,7th and 14th day were observed.Results In the treatment group,CRP and ET-1 were significantly decreased in the 7th and 14th day(P＜0.05,P＜0.01),and there was significant decrease only in the 14th day(P＜0.05)in the conventional therapy group.CRP and ET-1 levels in the treatment group were significantly different as compared with conventional thereapy group(P＜0.01).Conclusion Tongxinluo capsule may protect blood vessel endothelium through inhibiting CRP and ET-1 to decrease the inflammatory response of endangium.

Objective To investigate the clinical features of moyamoya disease complicated with Graves′disease and the efficacy of extra-and intra-cranial revascularization. Methods The clinical data of 4 patients with moyamoya disease complicated with Graves′disease were analyzed retrospectively. Among them,three were females and one was a male. Their mean age was 32 ± 7 years. After medical treatment, their thyroid function was normal. The patients were treated with superficial temporal artery-middle cerebral artery bypass grafting. Results (1) Three patients showed cerebral infarction and one showed frequent transient ischemic attack. DSA confirmed that 2 patients had unilateral moyamoya disease and 2 had bilateral moyamoya disease. Head MRI revealed brain infarcts. (2) The thyroid function was normal after drug treat-ment,the symptoms of moyamoya disease were stable in 3 cases. One patient had high metabolic symptoms, such as high fever and accelerated heart rate within one week after procedure. The patients were followedup for 6 to 18 months,one was good,3 were excellent,and there was no recurrence of Graves′disease. Postoperative head MRI revealed that the 4 patients did not have new brain infarcts. MRA showed that the arterial filling in cerebral sulci in the ischemic lesion areas was obviously improved compared with that before procedure. Retrograde filling of the ipsilateral middle cerebral artery M2-M3 segment was observed in 2 patients. Postoperative single photon emission computed tomography perfusion imaging revealed that the ischemic perfusion lesions on the operated sides were obviously improved compared with those before procedure. Conclusion When complicated with Graves′ disease,the symptoms of moyamoya disease will aggravate. It manifests as acute and chronic cerebral ischemia. After controlling the symptoms of hyperthyroidism,most cerebral ischemic symptoms can be alleviated. Superficial temporal artery-middle cerebral artery bypass grafting may establish an effective collateral circulation and improve the clinical symptoms.

Objective To explore the effect of clinical pharmacist on clinical rational use of antineoplastic drugs after participating in treatment group.Methods Retrospective research was used.According to whether there was a clinical pharmacist directly or indirectly involved in,all medical teams of the oncology department were divided into intervention group,advisory group and control group in our hospital.Intervention group was the medical team that had a specialist clinical pharmacist who could intervene irrational use of antineoplastic drug in the treatment on the spot.Advisory group was in the same area with the intervention group,and didn't have a specialist clinical pharmacist, but used to communicate with clinical pharmacist and take his medication advice,where clinical pharmacist indirectly involved in treatment.The control group was the medical group in the other area without clinical pharmacists of oncology department.The control group one and two were with the most beds among the control group.Randomly selected lung cancer,breast cancer,esophageal cancer,gastric cancer,colorectal cancer,gynecological cancer,liver/gallbladder/pancreatic cancer and other tumors patients from intervention group,advisory group,control group one and control group two,from January 2015 to December 2015,10 copies of each case,80 copies of each group.And antineoplastic drugs were commented specially.The information such as sex,age,clinical diagnosis,irrational antineoplastic drug use,adverse reaction and unexpected events and hospitalization time were recorded.Results The rate of irrational antineoplastic drug use of the intervention group (41.25%)was lower than the advisory group(80%),and was significantly lower than two control groups(147.50%,161.25%),advisory group was also lower than two control groups,but no significant differences between the two control groups(χ2 =0.193,P>0.05).Irrational chemotherapy, inappropriate usage and dosage and inappropriate indications were prominent problems in intervention group and advisory group.In addition,there were more improper solvent and contraindicated or adverse interaction problems in two control groups.Adverse events and incidence of unexpected events in intervention group (46.25%,12.50%) were significantly lower than those in two control groups[(73.75%,22.50%),(23.75%,18.75%)].Furthermore, the length of stay of intervention group patients was shortest in four groups (F=8.766,P<0.05).Conclusion By participating in the treatment group,clinical pharmacists can discover the irrational drug use and security risks in treatment,can provide medication guidance,consultation,publicity and other pharmaceutical service for specialist medical staff and patients.They will be more and more prominent in the treatment of cancer.

Objective To elucidate the effects of different modes of partial parenteral nutrition (PPN)on immunological function of T-lymphocyte in non small cell lung cancer(NSCLC)patients during chemotherapy.Methods Ninety-three patients with non-small cell lung cancer were randomly divided into three groups:the control group(30 patients),the low dose of PPN(32 patients) and the high dose of NNP(31 patients).Exactly the same chemotherapy was applied to each of three groups.During chemotherapy,three groups were supplied the same diet,the control group received conventional treatment;the low dose group and the high dose group received additional parenteral nutritional support besides diet.The low dose group was given 250 ml 9-AA daily and the high dose group was given 500 ml 9-AA daily.The T lymphocyte subsets CD3~+,CD3~++CD4~+ ,CD3~++CD8~+ and cells were detected respectively before and after chemotherapy.Results In all of the three groups,the percentage of NK cells,CD3~+ and CD3~++CD4~+ cells were decreased significantly before and after chemotherapy(all P＜0.05),In the control and low dose groups,NK cells changed more significantly after chemotherapy(P＜0.01).The percentages of CD3~+,CD3~++CD4~+,CD3~++ CD4~+/CD3~++CD8~+ of the low dose group and high dose group were higher than those of the control group before and after chemotherapy(all P＜0.05),the percentage of CD3~++CD8~+,CD3~++CD4~+/ CD3~++CD8~+ of the low dose group and hight dose group did not change notably(all P＞0.05). Conclusions The chemotherapy on patients with NSCLC will possibly cause malnutrition and immunosuppression.The benefits of giving 9-AA to NSCLC patients who were applying PPN and undergoing chemotherapy may include antagonizing immunological function aggravation,improving nutrition status and improving immunological functions of the T lymphocytes during chemotherapy.

Objective To study the mechanics of moderate and severe brain injury of pedestrians in road traffic accident by establishing the virtual model of impact occipital bone injury.Methods The clinical data were used to analyze comlnon mode and characteristics of moderate and severe brain injury of pedestrians.Then,the corresponding finite element model built by using Hypermesh software was used to to analyze the changes of intracranial pressures and compare with injury characteristics by using Ls-Dyna soft-ware. Results The conlmon injury mode of moderate and severe brain injury of pedestrians wag the con-tact impact of occiputal part,characterized by"eontrecoup injury",mainly including subdural hemorrhage,extradural hemorrhage and contusion in the opposite parts to the impact point.The simtdation resuhs showed that when the impact was at right occiputal bone.the peak value of condensing force decreased from the right occipital lobe.to the left frontal lobe,while the peak value of tension increased gradually and reached maximum at the surface of left frontal lobe. Conclusions Moderate and severe brain injury of pedestrian is commonly caused by impacting the occiputal bone in road traffic accident.The tension deformation in frontal or temporal lobes and the distribution of vessels in grey matter may be main biomeehanies leading to "contrecoup injury".
