Objective To explore the significances of the endoscopic diagnosis for chronic atrophic and histological assessment gastritis (CAG). Method Five hundred patients with CAG were determined by gastroscopy and the samples of gastric mucosa were examined by the pathology. Results Among 500 cases of CAG by gastroscopy, 429 cases were similar with the pathologic results and the coincidence rate of diagnosis with endoscopy and pathology was 85.8%(429/500), 370 cases had a change of atrophic gastritis in cirumjacent mucosa. Conclusion The coincidence rate of diagnosis under endoscopy and pathology is quite good in CAG.

End-tidal carbon dioxide tension or concentration monitoring is characterized with noninvasive,convenient and fast reaction,which Can be continuously monitored and dynamically displayed On electrocardiogram monitor.The technique has been extensively applied in the operation room,intensive care unit and emergency room.

Colorectal cancer is one of the most commonly seen malignant neoplasms in digestive tract.Most patients with colorectal cancer died of metastasis.The details of the metastasis-associated mechanisms are not elucidated completely.Recently,many genes that are involved in this course were detected.In this paper,the latest advances in those metastasis-associated genes and coding genes including C-myc,Ras,Her-2 ,p53,deleted in colorectal cancer gene (DDC),phosphatase and tensin homologue (PTEN),nm23 and other code genes,such as CD44,matrix metalloproteinases (MMPs) and mucins will be reviewed.

Objective To determine 1 hour plasma glucose cutoff value during OGTT to screen diabetes and IGR and its relationship with islet β cell function and insulin sensitivity. Methods 4731 subjects were recruited to perform an OGTT.The cutoff value of 1h-plasma glucose during OGTT was analyzed by receiver operating characteristic curve (ROC curve).And according to the two cutoff values,we classified all the subjects to three groups,and compared HOMA-IR,HOMA-β,insulinogenic index and shape index among groups,then analyzed its correlation with each parameter. Results According to ROC results, to diagnose type 2 diabetes mellitus,the optimal cutoff value of 1h plasma glucose during OGTT was 12.935mmol/L,with sensitivity of 81.52%,specificity of 86.94%. To diagnose impaired glucose regulation(IGR),the optimal cutoff value of 1h plasma glucose was 9.815mmol/L,with sensitivity of 74.96% and specificity of 77.86%. We classified all the subjects to three groups, and among the three groups the insulinogenic index, shape index, HOMA-IR, HOMA-β showed statistically significant difference (all P＜0.01). There was a negative correlation of OGTT-1hPG with insulinogenic index and HOMA-β(all P＜0.01) and a positive correlation of OGTT-1h PG with shape index and HOMA-IR (all P＜0.01). Conclusions To diagnose type 2 diabetes mellitus,the optimal cutoff value of 1h plasma glucose during OGTT is 12.935mmol/L.To diagnose impaired glucose regulation(IGR),the optimal cutoff value of 1h plasma glucose is 9.815mmol/L.And 1h PG can reflect the islet β-cell function and insulin resistance.

OBJECTIVE:To provide reference for the further improvement of national essential medicines system. METHODS:Taking theBull's-eyecity Chengdu as an example,based on the trading areas,the existing problems in implementing essential medicine system were analyzed by qualitative and quantitative research methods,and countermeasures were put forward. RESULTS:From the point of view of quantitative data,the first level trading areas of both proportions of medical personnel per thousand ur-ban population and numbers of primary medical and health institutions per 100 thousands population in Chengdu were the lowest. From 2010 to 2012,the outpatient and inpatients increased 1.09 million people and 0.16 million beds per day in Chengdu primary health care institutions,the largest increase in the first level trading areas,and increase and decrease in the second and third level trading areas;outpatient and inpatient drug costs fell respectively 4 yuan and 109 yuan,medicine proportion declined 6.7%,in-crease in the first level trading areas,and decreased to varying degrees in the second and third level trading areas. From the point of view of qualitative interviews,the service ability got enhancement,but still could not meet the services demand,especially the pressure in the first level trading areas near center district remains heavy;drug cost was under controlled,but the subsidies needs to be increased,the per capita drug costs in the first level trading areas remains high;the drug income and medicine proportion were inhibited,especially the significant fell in the second and third level area,but the decrease of income may restrict develop-ment. CONCLUSIONS:It is suggested that more targeted drugs are needed for meeting the services demand,more sophisticated policy are needed for improving the subsidies,and more comprehensive medical conditions are needed for ensuring institutions'de-velopment.

Objective To explore the lesion distribution pattern of poststroke pathological laughing or crying (PSPLC) by using MRI,and to discuss its pathogenesis. Methods All 24 cases selected from stroke patients who were treated in the department of neurology from May 2012 to December 2015 and had complete follow?up information after their discharge through 6 months were screened for pathological laughing and crying( PLC) . MRI characteristics of cases were analyzed retrospectively to identify lesion distribution. 28 cases with acute isolated pontine infarction who did not demonstrate PLC were enrolled as a comparison group. Lesion pattern difference between 14 cases of the pontine infarction with PLC and 28 cases of acute i?solated pontine infarction without PLC was compared. Results In these 24 cases,the highest occurrence rate of PLC was 41.67% in the second month. 15 cases had forced crying (62.5%),3 cases had forced laughing (12.5%),6 cases had pathological laughing or crying (25%). MRI studies showed lesion location in the left side were 3 cases,in the right side were 1 case,in the bilateral brain were 20 cases,in the basal ganglia were 9 cases,in the thalamus were 8 cases,in the corona radiata were 6 cases,in the semioval center were 5 cases, in the cerebral cortex were 4 cases,in the cerebellum were 4 cases and in the brain stem were 14 cases. In the cases of PLC with brain stem lesion,only 1 case was isolated pontine infarction,the other patients all combined with lesions of other parts. Compared with the pontine infarction with PLC,the isolated pontine in?farction without PLC was more likely to suffer with unilateral brain lesions(71%vs 50%),but there was no significant difference (χ2=0.844, P=0.358) . Conclusion PSFLC is not a rare complication after stroke, which is associated with multiple site of brain involvement especially pontine infarction.
