Objective To detect the atherosclerotic plaque by 64-slice CT angiography and study the correlation between vulnerable plaque and progressive stroke.Methods One hundred and one patients with cerebral ischemic stroke were divided into progressive stroke group (32 cases) and non-progressive stroke group (69 cases) according to the pathogenetic condition.The stenosis degree and vulnerability of artherosclerotic plaques was recorded and analyzed.Results The percentage of severe or occlusion carotid artery stenosis in progressive stroke group was 28.1％(9/32),which was significantly increased compared with that in non-progressive stroke group [8.7％(6/69)],and there was significant difference (P =0.011).The percentage of vulnerable plaque in progressive stroke group was 75.0％ (24/32),which was significantly increased compared with that in non-progressive stroke group [42.0％ (29/69)],and there was significant difference (P =0.002).There was significant difference in the ulcer plaque between two groups among the different type of vulnerable plaques (lipid core,surface irregularities,ulcers plaque) (P =0.016).Multivariate analysis showed that diabetes mellitus (OR =3.327,95％ CI:1.211-9.145) and vulnerable plaque (OR =3.699,95％ CI:1.292-10.589) was related with progressive stroke.Conclusions Vulnerable plaque and diabetes mellitus are the independent risk factors of progressive stroke.64-slice CT angiography can clear display carotid vulnerable plaque,which is important for clinical treatment.

Caudal-related homeobox transcription factor (CDX-2) is selectively localized in the fetal and adult mu-cosal epithelial nuclei of normal small and large intestines.CDX2 plays an important role in the regulation of cell proliferation and differentiation of the intestinal epithelium. Ec-topic expression of CDX-2 in the stomach, esophagus and other hollow organs might be a cause of intestinal metaplasia and adenocarcinoma. CDX-2 is expressed in both cultured and primary gallbladder carcinoma cells, and dysplasia.CDX2 is not detected in normal gallbladder and biliary tract mucosa. Ectopic CDX2 expression is an early event in gallbladder carcinogenesis. The frequency of CDX-2 expression is significantly higher in well-differentiated type than in the moderately and poorly differentiated tumors. The present study clearly showed that MUC2 expression in intestinal differentiation was dependent on the nuclear expression of CDX-2 in intraductal papillary neoplasia of the liver (IPNL)and mucinous intrahepatic cholangiocarcinoma (ICC) in the same manner as in the gastric mucosa and Barrett s esophagus. CDX-2 may also be a key factor in gallbladder carcinogenesis with intestinal differentiation and is a useful immuno-histochemical marker of intestinal differentiation in intestinal metaplasia of the gallbladder. CDX2-dependent regulation of cell proliferation may be an important factor in defining prognosis of patients with BTC.

Caudal-type homeoboxgene transcription factor 2 is one member of the caudal- related homeobox family,is a transeription factors important in intestinal epithelial development and in the differentiation and maintenance of the intestinal phenotype.In adulthood,these two proteins are strictly confined to the gut and are predominantly expressed by the epithelium of the small intestine and colon,but not by the normal epithelium of the oesophagus and stomach.In intestinal metaplasia,caudal-type homeohoxgene transcription factor 2 upregulation can be a direct effect of injurious agents on epithelial cells and/or can be due to the inflammatory environment of EpM,exposure to acid and/or bile acids may activate caudal-type homeoboxgene transcription factor 2 expression in human esophageal epithelial cells through promoter demethylation,and ectopie caudal-type homeoboxgene transcription factor 2 expression in esophageal squamous epithelia.It has been suggested to play an important role with retinoic acid,MUC2,p63 gene,BMP4 and many other factors working together to promote the development of this process in intestinal metaplasia and cancers.

Heterotopic gastric mucosa of the upper esophagus( HGMUE)is a rare esophageal disease. It is considered as a result of immature development of esophageal mucosal epithelium in embryonic period. Most of patients have no specific symptoms. The diagnosis of HGMUE is mainly based on endoscopy and biopsy. With the development of endoscopic technique,the detection rate of HGMUE is elevated and increasing attention has been paid to this disease. This article reviewed the clinical research on HGMUE.

ObjectiveTo observe the defervesce effect of bloodletting plus puncturing and cupping treatment in treating common cold due to wind-heat.MethodSixty-two patients with fever due to external contraction were randomized into a treatment group of 30 cases and a control group of 32 cases. The control group was intervened by muscular injection of Antodin plus oral administration ofQing Kai Linggranules 3 g, three times a day; the treatment group was by cupping and bloodletting at Dazhui (GV14) and Feishu (BL13), bloodletting at Shaoshang (LU11) and Shangyang (LI1), and cupping at back in addition to the intervention given to the control group. The clinical efficacy, treatment acting time (body temperature decreased by 0.5℃) and defervesce time were observed. ResultIn the treatment group, the acting time and defervesce time were respectively (6.11±2.18)h and (27.11±10.84)h, and total effective rate was 93.4%; in the control group, the acting time and defervesce time were respectively(14.31±5.43)h and (39.14±13.45)h, and total effective rate was 84.4%, and the differences were statistically significant (P<0.05).Conclusion Acupoint bloodletting plus bloodletting-cupping method can produce a significant defervesce effect in treating common cold due to wind-heat.

The reaction conditions, the spectrophotometric characteristics, and the analytical properties of the ion-association complex of 〔I2Br〕- with the basic triarylmethane dye such as ethyl violet (EV), crystal violet (CV), and victoria blue 4R (VB4R) in the presence of polyvinyl alcohol (PVA) were studied. The results showed that the color of the solutions would change obviously when the above ion-association complexes were formed in dilute phosphoric acid solution. The molar absorptivities (ε) of different systems are between 2.6×104 and 6.2×104 L*mol-1*cm-1. The sensitivity of the ethyl violet system is the highest among them. Beer′s law is obeyed in the range of 0～1.6　mg/L　I-　for ethyl violet system, 0～1.4　mg/L for crystal violet system, and 0～0.8 mg/L I- for victoria blue 4R system, respectively. The method can be applied to direct determination of iodide in aqueous solution. The method has good selectivity. A large amounts of halide ions, some other inorganic acid group ions and amount of common metal ions don′t interfere the determination of I-. This method was used to determine I- in kelp, laver and soy bean with satisfactory results

Objective To investigate the effects of different doses of remifentanil on the renal ischemiareperfusion (I/R) injury in rats. Methods Sixty male SD rats weighing 220-250 g were randomly divided into 5 groups ( n = 12 each): sham operation group (group S), model group (group M), low, median and high doses of remifentanil groups (RL, RM and RH groups). The rats were anesthetized with intraperitoneal 5% chloral hydrate 6 ml/kg. Renal ischemia was induced by clamping the bilateral renal arteries for 45 min using an atraumatwere infused via the caudal vein 15 min before ischemia respectively and the infusion was stopped at 30 min of reperfusion, while S and M groups received equal volume of normal saline instead. Blood samples were collected from the femoral vein at 30 min and 24 h of reperfusion for measurement of serum creatinine (Cr) and blood urea nitrogen (BUN) concentrations. The rats were sacrificed at 24 h of reperfusion and the renal tissues were removed for determination of MDA content, SOD and Ca2+ -ATPase activities. Pathological changes in renal tissues were observed with light and electron microscopes. Results Compared with group S, the concentrations of serum Cr and BUN and content of MDA were significantly increased, while activities of SOD and Ca2+ -ATPase were significantly decreased in the other 4 groups ( P ＜ 0.05 or 0.01). Compared with group M, the concentrations of serum Cr and BUN and content of MDA were significantly decreased, activities of SOD and Ca2+ -ATPase were significantly increased (P ＜0.05 or 0.01) and the pathological changes were reduced in RH, RM and RL groups. The plasma BUN and Cr concentrations and MDA content were decreased gradually and SOD and Ca2+ -ATPase activities were increased gradually with the increase in the doses of remifentanil in RL, RM and RH groups ( P ＜ 0.05 or 0.01 ).Remifentanil infusion significantly attenuated the pathologic changes in a dose-dependent manner. Conclusion Remifentanil can reduce the renal I/R injury in a dose-dependent manner by inhibiting lipid peroxidation and increasing Ca2+ -ATPase activity.

Hyperthermia therapy employs artificial heat to treat malignant tumors. Hyperthermia uses a variety of physical energy to produce thermal effects in the body tissue. Hyperthermia elevates the temperature of tumor tissues to a certain degree and makes it maintained for a certain period of time to kill cancer cells and prevent normal cells from damage. Compared with other conventional therapy, hyperthermia has its special advantages and has become one of the novel comprehensive medical treatments for cancer therapy. This paper briefly reviews the action mechanism on hyperthermia against tumors and its clinical application in the treatment of gastrointestinal cancer.

Objective To prospectively study the minimally invasive hematoma stereotactic aspiration and the recovery of neurological deficits after conservative medical treatment alone, as well as the incidence of post-stroke depression (PSD) in patients with intracerebral hemorrhage, so as to investigate the effect of minimally invasive hernatorna stereotactic aspiration on the recovery of neurological deficits and the incidence of PSD. Methods Fifty-five patients with intracerebral hemorrhage received minimally invasive hematoma stereotactic aspiration (n =25) and conservative medical treatment (n = 30), respectively. The neurological deficits of the patients were assessed by the National Institutes of Health Stroke Scale (NIHSS) at admission, day 14 and 90. The decreased values (all compared to baseline score) of the NIHSS scores were calculated at day 14 and 90, respectively; the modified Rankin Scale (mRS) was used to assess the disabled degree at day 90; the 17-item Hamilton Depression Rating Scale (HAMD) was used to assess the PDS status at day 14 and 90. The correlation between PSD and the degrees of neurological deficit and disability in patients was analyzed. Results The decreased value of the NIHSS score in the stereotactic group at day 14 and 90 was significantly higher than that in the conservative treatment group (all P ＜0. 05), and the value of the mRS score was significantly lover than that in the conservative treatment group at day90 (P＜0. 05). The incidence and the total incidence of PSD in the stereotactic group at day 90 were significantly lover than those in the conservative treatment group (all P ＜0.05). There were significant positive correlation between HAMD and NIHSS scores and HAMD and mRS scores. Conclusions The recovery of neurological deficits was faster after the minimally invasive hematoma stereotactic aspiration. The degree of disability in patients was lower, and the incidence of PSD was also lower than that in the conservative treatment group. PSD was closely correlated with the degrees of neurological deficits and disability.
