Chinese Journal of Postgraduates of Medicine 2014;37(6):39-41
Objective To investigate the change of lung function in children with atypical asthma and different lung function index to evaluate the difference of bronchial dilation test positive rate.Methods Seventy-one cases of atypical asthma children routine monitoring lung function,underwent bronchial dilation test,the airway index changes were observed.Results Seventy-one cases of atypical asthma children with big airways function index of forced expiratory volume in first second FEV1,percentage of FEV1 to forced vital capacity (FVC) were basic normal,and the reaction of small airways function index of forced expiratory flow at 25% of FVC,forced expiratory flow at 50% of FVC,forced expiratory flow at 75% of FVC,forced expiratory flow at 25%-75% of FVC were decreased in different degrees,and mainly for medium and severe damage.FEV1 as evaluation index,the positive rate of bronchial dilation test diastolic was 47.9% (34/71),and forced expiratory flow rate at 25%-75% in FVC as evaluation index,the positive rate of bronchial dilation test was 69.0% (49/71),there was significant difference (x2 =8.086,P =0.004).Conclusions Lung function changes in atypical asthma children are mainly on small airways,and mainly for medium and severe damage,the bronchial dilation test positive rate in such children using the evaluation,forced expiratory flow rate at 25%-75% in FVC can assist FEV1,decrease the rate of misdiagnosis and missed diagnosis.

Obstructive sleep apnea (OSA)is a high incidence of potentially dangerous disease,characterized by intermittent hypoxia or hypercapnia.It is an independent risk factor for ischemic stroke.Currently a number of studies have confirmed OSA closely associated with oxidative stress.In this paper,the complex mechanisms of oxidative stress in the OSA and the occurrence of stroke will be reviewed,such as promoting atherosclerosis,damaging the mitochondria,ischemia -reperfusion injury,ischemic preconditioning.To investigate the relationship between OSA,oxidative stress and stroke from molecular mechanisms.

OBJECTIVETo investigate changes in clinicopathological features and survival of patients with gastrectomy at a single institution in China.
METHODSFrom January 1990 to December 2009, clinicopathological data of 2518 cases of gastric cancer patients who underwent surgical resection in the Sun Yat-sen University Cancer Center were analyzed retrospectively. The overall survival rate was determined using Kaplan-Meier method and log-rank test was used to determine significance. The prognosis was analyzed using univariate analysis and multivariate analysis by Cox proportional hazards model. Clinical features, pathological findings and survival differences were compared in this cohort between two consecutive periods(1990-1999 and 2000-2009).
RESULTSThe 5-year survival rates for the whole cohort and those undergoing radical resection was 48.1% and 53.7%, respectively. In the first period, the 5-year survival rate for the whole cohort and for patients undergoing radical resection was 40.1% and 45.7%. In the second period, the 5-year survival rates for whole cohort and for patients undergoing radical resection was 51.5% and 57.1%, respectively. For those who underwent radical resection, the mean number of lymph node dissection was significantly higher in the recent period (20.1±8.3 vs. 9.5±6.0, P<0.01). On multivariate analysis by means of the Cox proportional hazard model, age, location, tumor size, histological type, radical resection, lymphatic/venous invasion, depth of invasion, nodal status, number of retrieved lymph nodes, and treatment period were independent factors (P<0.05). The constitution, number of retrieved lymph nodes, and survival rate were all improved between the two intervals (P<0.05).
CONCLUSIONThe overall survival rate has gradually increased in gastric cancer patients over the past 20 years.

Objective To analyze the effects of Hual qi huang granules on children with mycoplasma pneumoniae pneumonia.Methods A randomized,multicenter parallel controlled clinical trial was carried out.A total of 3 000 cases of hospitalized children with mycoplasma pneumoniae pneumonia were selected.All of them were given treatment for mycoplasma pneumoniae pneumonia with macrolide antibiotics and symptomatic treatment.They were randomly divided into 2 groups:research group and control group.The children of research group were give oral Huai qi huang granules for three months.According to the classification of pneumonia,these two groups were divided into:lobar pneumonia research group,lobar pneumonia control group,lobular pneumonia research group,lobular pneumonia control group.The hospitalization duration of fever,length of hospital stay,the absorption area of lung inflammation and pneumonia severity sores were observed.The frequency of upper respiratory infections,bronchitis,pneumonia were observed in 3 months after discharge.Results 2 378 cases were investigated.The hospitalization duration of fever,length of hospital stay of research group were significantly shorter than that of in control group (P < 0.001).The children with lobar pneumonia,2 weeks after treatment,the absorption of consolidation of the lobar pneumonia research group is significantly better than lobar pneumonia control group (P <0.001).After two weeks treatment,the pneumonia scores of lobar pneumonia research group is lower than lobar pneumonia control group (P < 0.05).Followup of 3 months after hospital discharge,frequency of upper respiratory infection and bronchitis of research group,were significantly lower than that of control.In addition,appetite increased significantly in research group than control (P < 0.001).There are 21 cases with drug associated adverse reactions (mild diarrhea),including 12 cases of research group,9 cases of control group,and there was no statistical significance (P >0.05).Conclusion Standard treatment combined with oral Huai qi huang granules in the treatment of mycoplasma pneumoniae pneumonia,can significantly shorten hospitalization duration of fever,length of hospital stay and reduce the severity score of pneumonia.Three months oral Huai qi huang granules can significant reduce the frequency of respiratory infections and bronchitis,also can increase patients appetite,and be safe.
