Objective To study the diagnostic value of TCD and MRI in transient ischemic attack (TIA) of internal carotid artery system.Methods The clinic data was analyzed to contrast the relation of the clinic manifestation and the TCD and MRI results of 66 patients suffered from TIA of the internal carotid artery system.then chi-square test was adopted.Results In TIA interval, extensive hemodynamics changes were occurred in the intracranial arteries among 60 patients(90 9%), and 22 patients(33 3) presented different degrees of stricture on the corresponding symptom side, MRI test showed lacunar infarct or small infarct foci among 50 patients(75 8%), and ischemic leukoenporosis among 35 patients(53 5%). But the foci took a two-side distribution and were relatively symmetrical. No significant correlation existed between the symptom and the foci,and the positive rate of TCD did not show remarkable difference between the symptoms and the foci, and the positive ratio of TCD did not show remarkable difference whether the MRI infarct foci existed or not. Meanwhile, there were also no notable distinction between the stricture change of arteries in the corresponding symptom side with the infarct foci and that of arteries in the corresponding symptom side without the infarct foci.Conclusions TCD can find the change of arteries related in TIA of the internal carotid artery system, and can be used as routine and primary screening. While MRI may bear no special clinic significance to TIA of the internal carotid artery system, but it has localization meaning to CWS, a clinical subtype of TIA.

Aiming at the weakness of the medical graduate students' ideological and political education,we developed the new mode via investigation and surveying,allowing for the medical characteristics. We suggested that we should bring into full play the tutors and their groups function and excavate the connotation of groups’ morality education on the basis of the scientific research groups to develop the medical students' ideological and political education.

Objective To evaluate the perioperative blood loss and blood transfusion in liver transplantation patients.Methods Retrospectively selected and classified 119 patients with liver transplantation medical recordsaccording to the clinical diagnosis of age,gender.Analyzed (disease)patients' blood coagulation index 24 h before surgery,intraoperative and postoperative perioperative bleeding,and blood red blood cell suspension,frozen plasma,cold precipitation,coagulation factor injection lossplateletpheresis.Results There were no significant differences in the amount of blood loss and the amount of blood preparations duringthe perioperative period of liver transplantation according to the age and sex of patients (P＞0.05);According to the clinical diagnosis of different groups,the diagnostic group (primary liver cancer group,hepatitis B cirrhosis group and severe hepatitis group) patients with a single platelet transfusion dosewas similar (P＞0.05)withsuspended red blood cells (U) at 8.4+11.9,16.2+15.7,18.1+13.5,frozen plasma (U) at 8.2+7.1,18.1+15.6 and 18.2+ 17.9 respectively andcold precipitation (U) at 9.5+ 8.2,17.1 + 16.318.5 + 16.4 (P＜ 0.05);The diagnosis group surgery before and after immediate PT (s) were 15.6+3.8,24.6+4.1,APTT (s) were 44.3+5.8,84.9+9.2,TT (s) were 20.4 +4.5,40.1+6.2,and Fib(s) were 2.6+0.8 and 1.3+0.9 (P＜0.05);however,there was no significant difference in the 24 h PT,APTT,TT and Fib between the two groups after diagnosis (P＞0.05).Conclusion Ascientific,safe and reasonable selection of perioperative blood preparation for clinical diagnosis for different liver transplantation patients is critical to the success rate and prognosis of liver transplantation;the evaluation of coagulation indexes at each interval can help guiding the blood transfusion during liver transplantation.

In order to compare the effects of several experimental renal calcium oxalate stones formation models in rats and to find a simple and convenient model with significant effect of calcium oxalate crystals deposition in the kidney, several rat models of renal calcium oxalate stones formation were induced by some crystal-inducing drugs (CID) including ethylene glycol (EG), ammonium chloride (AC), vitamin D(3)[1alpha(OH)VitD(3), alfacalcidol], calcium gluconate, ammonium oxalate, gentamicin sulfate, L-hydroxyproline. The rats were fed with drugs given singly or unitedly. At the end of experiment, 24-h urines were collected and the serum creatinine (Cr), blood urea nitrogen (BUN), the extents of calcium oxalate crystal deposition in the renal tissue, urinary calcium and oxalate excretion were measured. The serum Cr levels in the stone-forming groups were significantly higher than those in the control group except for the group EG+L-hydroxyproline, group calcium gluconate and group oxalate. Blood BUN concentration was significantly higher in rats fed with CID than that in control group except for group EG+L-hydroxyproline and group ammonium oxalate plus calcium gluconate. In the group of rats administered with EG plus Vitamin D(3), the deposition of calcium oxalate crystal in the renal tissue and urinary calcium excretion were significantly greater than other model groups. The effect of the model induced by EG plus AC was similar to that in the group induced by EG plus Vitamin D(3). EG plus Vitamin D(3) or EG plus AC could stably and significantly induced the rat model of renal calcium oxalate stones formation.

Objective To summarize the clinical features, diagnosis and treatment of Ménétrier disease in China. Methods A systematic review of Ménétrier disease in China was performed. Four electronic databases were searched from 1993 to 2008 including CNKI and Wanfang seeking studies about pathologically performed Ménétrier disease. Results Data of 95 patients with Ménétrier disease from 62 studies was included. There were 74 males and 21 females. The mean age of onset in adults was (47.4± 5.3) years . The process of the disease was longer in male individuals that in female individals (47.5 months vs. 13.7 months, P<0.05). The main symptoms included abdominal pain (76.8%), weight loss (42.1%), anorexia (40.0%) and edema of lower extremities (36.8%), etc.Hypoproteinemia was accounted for 71.6 % and most of the patients had hypochlorhydria. The typical giant hyperplastic gastric fold was found in 88.4 % of the patients under endoscopy. The diffuse type was in predominance and mainly involved the greater curve of the stomach (55.3 %). Whereas 5.3 patients were accompanied with gastric cancer. The misdiagnostic rate of the disease was 31. 6%,which accounted for 50% in surgically treated patients. Conclusions In China, the Ménétrier disease is predominant in middle-aged males, and the process is longer in males than in females. Misdiagnosis is related to existence of weight loss and hypoproteinemia. Most of the patients with Ménétrier disease have a good prognosis even the disease process is long.

Objective：To investigate the changes of calcitonin gene-related peptide immunoreactive (CGRP-IR)nerve fibers in rat dental pulps during acute inflammation. Methods： Rat acute pulpitis model was established by silk thread ligation and the change of CGRP-IR nerve fibers was observed with immunohistochemical method.Results： In radical pulp,the CGRP-IR nerve fibers became denser and more heavily stained；in the coronal pulp,the number of CGRP-IR nerve fibers decreased,but the background staining was heavier. Conclusion： During acute inflammation,the amount of CGRP increases in dental pulps, and is released into the surronding tissue in a large scale in the coronal region.

Objective To investigate the prevalence of Helicobacter pylori (Hp) infection among health checkup population in Xiamen area during 2012-2014,and evaluate the potential predictors for Hp infection.Methods A cross-sectional study was conducted among health checkup population in the Zhongshan Hospital during 2012-2014.Potential participants completed 13C breath tests for helicobacter pylori infection.An epidemiological questionnaire was used to collect data on socio-demographic characteristics,the awareness of Hp-related information,the history of gastrointestinal diseases or symptoms,life styles and relevant data for each participant.Univariate and multivariate logistic regression analyses were performed to evaluate the associations of Hp infection with potential predictors.Results Three groups of individuals with 1 631,1 766,and 5 257 persons who underwent health checkup were screened for Hp infection,and Hp prevalence was 48.9％,49.8％,and 50.5％ during 2012-2014,respectively.No significant difference in Hp prevalence was found between both sexes.A total of 1444 acceptible questionnaires were used to evaluate the associations between Hp infection and potential predictors and Hp infection was 47.9％ among 1 444 eligible participants.In the multivariate logistic regression model,Hp infection was found to be associated significantly with having ever tested for Hp infection (OR,0.67;95％CI:0.51-0.88;P=0.004),the history of stomachache or gastrectasia (OR,2.19;95％ CI:1.73-2.78;P＜0.001),and alcohol drinking (OR,1.38;95％ CI:1.11-1.71;P=0.004).The higher the severity of Hp infection,the higher the prevalence of stomachache or gastrectasia,and smoking and alcohol drinking.However,the prevalence of smoking and alcohol drinking decreased among those with the highest severity of Hp infection.Conclusion The prevalence of Hp infection in Xiamen area was slightly lower than the national Hp prevalence among natural population,but this prevalence reached 50％.The awareness rate of Hp infection was still low.The prevalence of stomachache or gastrectasia among our study population presented positive correlation with the severity levels of Hp infection.More attention should be paid to Hp screening and treatment among those with gastrointestinal diseases or symptoms.

Objective To explore the short-term and long-term effects ofapplication of Percutaneous Transhepatic Cholangioscopic Lithotripsy on the treatment of hepatolithiasis. Methods Eighty-threecases of hepatolithiasis were treated with the PTCSL and the other 87cases were treated with the Laparoscopic exploration lithotomy.The general clinical parameters , curative effect in the near future and long-term curative effect were anlyzed. Results No significant differences were found between the two groups in the general clinical parameters (P>0.05). The operation time,intraoperative blood transfusion volume and intraoperatve blood soss in group A were significantly shorter than those in group B(P<0.05, respectively). The original calculi residual rate was 2.4%, the eventually calculi residual rate was 4.8%and the recurrent cholangitis was4.8%in the model of PTCSL (Group A). The original calculi residual rate was 18.4%, the eventually calculi residual rate was 23.0% and the recurrent cholangitis was 23.0%in the model of Laparoscopic exploration lithotomy (Group B), with significant difference between these two groups (P<0.05). The calculi recurrence rate of group A was 12.0%,the calculi recurrence rate of group B was 22.9%,withno significant difference between these two group (P>0.05). No patients died in each group. The results of complications showed thatthe incidence of residual calculi of group A was significantly lower than that of group B (P<0.01). Conclusions Compared with the model of Laparoscopic exploration lithotomy, the PTCSL was more safe, minimally invasive and effective. The short-term efficacy of the model of PTCSL was better than that of the model of Laparoscopic exploration lithotomy.
