Objective To investigate clinical treatment status in early hospitalized patients with acute ST-segment elevated myocardial infarction(STEMI).Methods The data of hospitalized patients with STEMI admitted between January 2001 and June 2005 were retrospectively collected and studied from medical records of the 2nd Hospital of Tianjin Medical University.Results A total of 773 cases were investigated,71.80% of the patients were male,the median age was 66.0 years,and the hospitalization duration was 11.0 days.The median duration from the onset of STEMI to the arrival in the wards was 210 min.The median initiation time of door-to-needle or door-to-balloon treatment for reperfusion therapy was 60 and 100 minutes,respectively.As to the selection of the reperfusion strategies,patients who were male,younger(age

Objective To investigate the prevalence of macula choroidal neovascularization(CNV) in high myopia patients and the associated risk factors.Methods Fifty-six outpatients(112 eyes) with high myopia were medically examined from Mar.2008 to Jun.2009.The inspection items,including A scan,B scan,diopter and optical coherence tomography(OCT),were carried out to check whether CNV existed and its growth fashion.The patients' basic status,main symptoms and the pathologic change in macula were recorded.Results The prevalence of CNV in the 56 outpatients(112 eyes) was 14.3%.Gender showed no correlation with CNV(r=-0.015,P=0.879),while age(r=0.629,P=0.000),diopter(r=0.725,P=0.000),axial length(r=0.236,P=0.013),posterior scleral staphyloma(r=0.344,P=0.000),atrophy of choroid and retina in posterior pole(r=0.421,P=0.000),lacquer crack(r=0.421,P=0.000) and Fuchs spot(r=0.519,P=0.000) were significantly correlated with the prevalence of CNV.Conclusions CNV may highly occurred in the patients with high myopia.Posterior scleral staphyloma,atrophy of choroid and retina in posterior pole,lacquer crack,Fuchs spot,age,axial length and diopter seem to be the risk factors for the occurence of CNV.

In order to investigate the dynamic changes in nitric oxide synthase (NOS) activity in organs during traumatic shock and to evaluate the effects of inhibitor of NOS and L Arginine (L Arg) on traumatic shock, rat model of traumatic shock was established, and the constitutive NOS and inducible NOS in the heart, small intestine, liver, lung , spleen were measured 0 5h, 3h, 5h after traumatic shock. Followed by intravenous injection with aminoguanidine (AG ), N G nitro L arginine methyl ester (L NAME), or L Arg, NOS were again measured, and the survival time and 24h survival rate were recorded. It was found that in normal rats cNOS was expressed in all organs, but only a weak iNOS expression in lung and liver. Half an hour after shock, cNOS was elevated in almost all organs in various degrees but there was no change in iNOS. 3h after shock, an increase in iNOS activity and a decrease in cNOS were observed. The iNOS was synthesized in large quantity 5h after shock. AG and L Arg markedly prolonged the survival time but L NAME did not in shock rats. AG inhibited the activity of iNOS but promoted the synthesis of cNOS, and both NOS were inhibited in L NAME group, but not in L Arg group. The results that iNOS was synthesized in large quantity only at later period of traumatic shock. To treat shock, the inhibitors of NOS and L Arg should be given according to the degree of shock, the dosage of drugs, and the time of administration

Objective To investigate the prevalence, clinical features and complications of gastrointestinal diverticula in Chinese people. Methods 551 patients with gastrointestinal diverticula were analyzed retrospectively. Results Among the 551 patients, 58.6% were over 60 years, and 11.6% were below 40 years. The incidence of esophageal diverticula, gastric diverticula, duodenal diverticula, jejunoileal diverticula and diverticula of the large intestine was 2.5%, 1.8%, 71.7% , 12.7% and 11.3% respectively. There were 6 and 11 patients, 9 and 6 patients, 69 and 271 patients, 1 and 24 patients, and 21 and 33 patients who were diagnosed by endoscopy and double contrast barium examination respectively. Among the 14 esophageal diverticula patients, the incidence of midesophageal diverticula (78.6%) was higher than that in pharyngoesophageal diverticula (11.2%). Among the 62 diverticula of the large intestine patients, the incidence of right side diverticula (56.5%) was higher than that of left side diverticula (38.7%). Almost esophageal diverticula and gastric diverticula were asymptomatic, while about half of the diverticula of the small and large intestine was symptomatic. The incidence of cholelithiasis and pancreatitis in patients with duodenal diverticula was 34.2% and 10.1% respectively. And the incidence of cholelithiasis and pancreatitis in descending segment was significantly higher than that in non descending segment ( P

Objective To evaluate the value of detecting chlorophyll related genes of plankton in the diagnosis of drowning. MethodsEighteen rabbits were divided randomly into three groups: death by drowning (n=10), postmortem submersion (n=6) and control (n=2). The heart blood, lung, liver, kidney and brain tissues were taken from every rabbit. After isolated plankton from tissues with percoll and extracted their DNA, the chlorophyll-related genes, including EG (EG1 and EG2) and SK (SK1 and SK2), were detected using PCR technique. Meanwhile, diatom test was also performed from lung and liver tissues by nitric acid digestion method. ResultsFor the drowning group, the specific amplification products for EG1 were detected from 9 samples in heart blood, 10 samples in lung, 9 samples in liver, 7 samples in kidney and 8 samples in brain. The products for EG2 were detected from 8 samples, 10 samples, 7 samples, 5 samples and 7 samples accordingly. There were a small number of positives in heart blood, lung and kidney with SK1 and SK2 (≤2). For the postmortem submersion group, only one case was positive from heart blood and lung tissue respectively for EG1. No amplified product was detected for EG1 and EG2 in various tissues in control group, and also no product was detected for SK1and SK2 in other groups. In addition, diatoms were detected from 9 lung and 3 liver tissues in drowning group with the nitric acid digestion, and only one sample of lung was positive in the postmortem submersion group. ConclusionThe detection rate of the chlorophyll-related gene EG with PCR method was higher than that of diatom with nitric acid digestion method in drowning victims, and it can be used as a potentially useful tool for diagnosing drowning.
