Objective To investigate the expressions and clinical significance of Ki-67,p53,and survivin in esophageal cancer and precancerosis.Methods The expressions of Ki-67,p53,and survivin proteins were detected by immunohistochemical staining in 40 normal esophageal mucosa,136 precancerosis (42 mild atypical hyperplasia,43 moderate atypical hyperplasia,and 51 severe atypical hyperplasia),and 68 esophageal cancer tissues.The correlation of three proteins expressed in esophageal carcinoma tissues was analyzed.Results The positive expression rate of Ki-67 was 0 (0/40)for normal epithelium,35.7％ (15/42) for mild dysplasia,51.2％ (22/43) for moderate dysplasia,74.5％ (38/51) for severe dysplasia,92.6％ (63/68) for squamous carcinoma,respectively.The positive expression rate of p53 protein was 0 (0/40) for normal epithelium,28.6％ (12/42) for mild dysplasia,46.5％ (20/43) for moderate dysplasia,52.9％ (27/51) for severe dysplasia,67.6％ (46/68) for squamous carcinoma,respectively.The positive expression rate of survivin protein was 0 (0/40) for normal epithelium,38.1％ (16/42) for mild dysplasia,55.8％ (24/43) for moderate dysplasia,64.7％ (33/51) for severe dysplasia,89.7％ (61/68) for squamous carcinoma,respectively.Rank correlation analysis showed that abnormal expressions of Ki-67,p53,and survivin were correlated significantly with the pathological grading of the lesions (r =0.637,0.454,0.590,P ＜0.01).The expressions of Ki-67,p53,and survivin were positively correlated in esophageal carcinoma (r =0.407,0.646,P ＜ 0.01).Conclusions The abnormal expressions of Ki67,p53,and survivin were associated with the processes of the esophageal canceration,and the joint detection with three parameters has important clinical value.

ObjectiveTo explore the relationship between chronic kidney disease (CKD) and cerebral small vessel disease (SVD) in elderly patients. MethodsOne hundred and fifty-two elderly male CKD patients for experimental group and 158 elderly male for control group were recruited. Demographic data and vascular risk factors were recorded. White matter lesion (WML) was semi-quantitatively assessed by cerebral magnetic resonance imaging (MRI), and lacunar infarction (LI) was also calculated. Results(1) The prevalenees of hypertentsion and diabetes mellitus were higher in elderly CKD patients than those in control group (30. 9% vs. 19.0%, 23.7%vs. 14.6%;both P～0. 05). (2) The percentages of grade 2 and grade 3 WMLs were higher in elderly CKD patients than those in control group (34.9% vs. 24.1%, 25.7% vs. 16.5%;both P<0.05). Prevalence of LI was higher in elderly CKD patients than that in control group (45.4% vs.25.3% ,X2= 13. 70, P<0. 05). The similar Resultswere also obtained except for control subjects with hypertension and diabetes mellitus. (3) The logistic regression analysis showed that age, hypertension and low glomerular filtration rate (GFR) were closely associated with SVD in elderly CKD patients. ConclusionsHypertention and diabetes mellitus are risk factors for CKD in elderly patients. SVD is associated with CKD, and age, hypertension and low GFR may be risk factors for SVD in elderly CKD patients.

Objective To assess the clinical significance of reverse trendelenburg position in preventing postoperative nausea and vomiting(PONV)in thyroid surgery.Methods 110 patients with papillary thyroid carcinoma(PTC) admitted from Feb.2013 to Mar.2014 were prospectively divided into experimental group and the control group according to whether reserve trendelenburg position was adopted.Univariate and multivariate method were used to analyze relations between PONV and surgical position,gender,age,body mass index,hypertension,surgical time,ASA classification,anesthesia,and motion sickness.Results Of the 110 cases of PTC,the incidence of PONV was 16.28％ (7/43) in the experimental group while it was 37.31％ (25/67) in the control group.The difference had statistical significance(P ＜ 0.05).Statistical analysis showed that PONV was related to patients'gender,surgical position,surgical time,and motion sickness,while only surgical position and motion sickness was the independent risk factors.Conclusion Reverse trendelenburg position surgery can help to prevent PONV and promote recovery.

Objective To investigate the characteristics of traditional Chinese medical syndrome types of fulminant and epidemic dengue fever patients admitted in Guangzhou and Xishuang banna in the year of 2013,and to ex plore the differences of etiology and pathogenesis, illness, and treatment for the patients in the two regions. Methods We collected the clinical data of 78 cases receiving integrative Chinese and western medicine from 255 patients admitted in Guangzhou Municipal Eighth People’s Hospital, and the clinical data of 39 cases receiving integrative Chinese and western medicine from 120 patients admitted in the People’s Hospital of Xishuangbanna Dai Nationality Autonomous Prefecture in the year of 2013. The traditional Chinese medical syndrome types and the syndrome scores of the total of 117 cases were investigated. The method of phenology was used for the analysis of epidemic time and epidemic region of dengue fever, and the theory of defense-qi-nutrient-blood syndrome differentiation of seasonal febrile diseases was used for the analysis of etiology and pathogenesis of dengue fever. Results ( 1) Dengue fever was epidemic in the first ten days of July and in the middle ten days of November of the year 2013 in Guangzhou region, and was epidemic in the middle ten days of August and the first ten days of October in Xishuangbanna region. The epidemicity of dengue fever in Guangzhou covered the end of summer and the whole autumn, and then disappeared before the coming of winter. In Xishuangbanna , the epidemicity of dengue fever was obvious in autumn, and disappeared in late autumn. ( 2) In the two hospitals, dengue fever patients were dominated by the syndromes of excessive heat in both Qifen and Xuefen, blood stasis blended with toxicity, excessive heat in Qifen, and lingering pathogens in order. (3) Before treatment, the scores of fever were higher in patients of Xishuangbanna hospital than those in patients of Guangzhou Eighth People’s Hospital ( P<0.01) . After treatment for 3 days, fever scores were improved in both hospitals (P<0.05 or P<0.01), but the differences between the two hospitals were insignificant (P>0.05) . After treatment for 6 days, fever disappeared in patients of both hospitals. (4) Before treatment, the scores of syndromes were higher in patients of Xishuangbanna hospital than those in patients of Guangzhou Eighth People’s Hospital ( P<0.05) . After treatment for 3 days, syndorme scores were improved in both hospitals ( P<0.01) , but the syndrome scores were higher in Xishuangbanna hospital than those in patients of Guangzhou Eighth People’s Hospital. After treatment for 6 days, syndrome scores were much improved in patients of both hospitals compared with those after treatment for 3 days (P<0.01) . Conclusion In dengue fever patients admitted in Guangzhou and Xishuangbanna region, the syndrome of excessive heat in both Qifen and Xuefen is the leading type, and then comes blood stasis blended with toxicity. The illness state of patients in Guangzhou region is milder than that of the patients in Xishuangbanna region, the time for symptom relief is about one week, and similar therapeutic effect can be achieved in the two regions .

retrospective cohort study was adopted.The clinical data of 343 patients with intermediate-stage hepatocellular carcinoma (HCC) who were admitted to the Eastern Hepatobiliary Surgery Hospital of the Second Military Medical University between February 2008 and January 2010 were collected.All the patients received the detailed medical history collection,physical examination,laboratory and imaging examinations after admission,and then hepatectomy was performed according to the results of above examinations.Research methods:(1) patients were allocated into the B1,B2 and B3/4 groups based on the Bolondi's substaging model,and the prognostic analyses among groups were conducted.(2) The related factors affecting the prognosis of patients in the B1 and B2 groups were analyzed.(3) The patients in the B1 and B2 groups were allocated into the 4 groups [patients of B1 group with negative microvascular invasion (MVI) were divided in the M1 group,patients of B1 group with positive MVI in the M2 group,patients of B2 group with negative MVI in the M3 group and patients of B2 group with positive MVI in the M4 group] according to the situations of MVI,and stratified analysis was conducted.Observation indicators:basic clinical and pathological features and survival of patients in the B1,B2 and B3/4 groups were observed.Risk factors analysis affecting the prognosis of patients and stratified analysis of MVI in the B1 and B2 groups were conducted.All the patients were followed up by outpatient examination and telephone interview up to February 2014,and the abdominal ultrasound,liver function and serum alpha-fetoprotein (AFP) tests was performed once every 3 months within 2 years postoperatively and once every 6 months after 2 years postoperatively.The continuous variables and categorical variables were respectively represented as M(Qn) and percentage.The comparisons of continuous variables and categorical variables among groups were analyzed by ANOVA or Kruskal-Wallis test and chi-square test or Fisher exact probability,respectively,and one-way ordinal categorical variables were analyzed by the Kruskal-Wallis test.The survival curve was drawn using the KaplanMeier method.The univariate analysis and multivariate analysis were done using the Log-rank test and COX regression model.Results (1) The basic clinical pathological features:of 343 patients with HCC,143,183 and 17 patients (12 in the B3 substaging and 5 in the B4 substaging) were respectively allocated into the B1,B2 and B3/4 groups.There were statistically significant differences in the age,peritoneal effusion,total bilirubin (TBil),albumin (Alb),alanine transaminase (ALT),prothrombin time (PT),platelet (PLT),alpha-fetoprotein (AFP),extent of liver resection,surgical margin ivasion,tumor diameter,number of tumor,Edmondson-Steiner grade,Up-to-7 score,Up-to-7 standard and Child-pugh score among the 3 groups (F =3.377,NA,11.245,32.616,6.884,11.564,33.100,12.902,NA,NA,239.089,10.357,x2=8.906,F =251.508,x2 =343.000,106.790,P ＜ 0.05).(2) Survival of patients:all the patients were followed up for 2.8-70.8 months with a median time of 38.7 months.The 1-,3-,5-year survival rates and median survival time in the B1,B2 and B3/4 groups were 85.8％,72.8％,52.9％ and 63.2％,47.5％,16.8％ and 45.5％,30.4％,8.4％ and 55.1 months,35.1 months,12.2 months,respectively,showing a statistically significant difference (x2 =22.800,P ＜ 0.05).(3) Risk factors analysis:the results of univariate analysis showed that the peritoneal effusion,Alb,Hb,AFP,esophagogastric varices,surgical margin invasion,tumor diameter,MVI and Edmondson-Steiner grade were related risk factors affecting the prognosis of patients with HCC after hepatectomy [HR =2.04,2.46,2.50,1.78,1.55,3.54,1.71,1.76,1.69,95％ confidence interval (CI):1.13-3.69,1.20-5.02,1.51-4.15,1.29-2.45,1.06-2.25,1.65-7.61,1.23-2.38,1.23-2.51,1.08-2.64,P＜0.05].The results of multivariate analysis showed that the Alb ＜ 35 g/L,Alb ＜ low limit of normal,tumor invading to surgical margin,tumor diameter ＞ 5 cm and positive MVI were independent risk factors affecting the overall survival of patients with HCC after hepatectomy (HR =2.82,2.16,2.93,1.48,1.53,95％ CI:1.37-5.80,1.27-3.69,1.33-6.44,1.05-2.09,1.06-2.22,P＜0.05).(4) There were 61,82,57 and 126 patients in the M1,M2,M3 and M4 groups,and M2 and M3 groups were merged into the M2/3 group because of being similar survival situations of patients.The 1-,3-,5-year survival rates and median survival time in the M1,M2/3,and M4 groups were 90.0％,83.2％,67.7％ and 68.8％,59.9％,41.6％ and 52.7％,42.1％,23.6％ and 69.0 months,49.2 months,24.9 months,respectively,with a statistically significant difference among the 3 groups(x2=20.200,P ＜ 0.05).Conclusions The Bolondi substaging model produces an optimal survival prediction for patients in intermediate stage of BCLC after hepatectomy.The patients in the B1 and B2 substaging have better long-term survival outcomes after hepatectomy.

Objective To explore the morphology,cell phenotype and cell function in dendritic cells (DCs) derived from bone marrow after treatment with Sirolimus or Sirolimus combined with sTNFRI-IgGFc gene segment transfection.Method DCs were divided into 5 groups (imDCs,mDCs,Rapa-DCs,sTNFRI-DCs and Rapa-sTNFRI-DCs) according to different interventions.The expresson of MHC-Ⅱ,CD80 and CD86 was detected by flow cytometry.T cell proliferation of the mixed lymphocyte reaction was evaluated by MTT method.The levels of IL-12,IFN-γ and sTNFRI-IgGFc were determined by ELISA.Result On the day 10,the flow cytometry showed that the expression levels of MHC-Ⅱ,CD80 and CD86 on the cell surface in Sirolimus group were significantly higher than the other groups (P＜0.05).The expression level of CD86 in Rapa-sTNFRI group was significantly lower than in imDC group (P＜0.05).MTT results demonstrated that T cell proliferation ability in Sirolimus group,sTNFRI group and Rapa-sTNFRI group were reduced as compared with mDC group (P＜0.05).The ELISA results revealed that the levels of IL-12 and INF-γ in rnDC group were significantly higher than other groups (P＜0.05).The levels of IL-12 and INF-γ in Rapa-sTNFRI group were significantly lower than other groups (P＜0.05).Conclusion Sirolimus combined with modified sTNFRI-IgGFc gene could synergistically inhibit maturation of DCs more effectively than Sirolimus or modified sTNFRI-IgGFc gene used alone.

The clinical characteristics and radiological data of 6 cases of sacral agenesis in one single family were analyzed and a literature review was performed.On magnetic resonance imaging (MRI),all of them presented with a partial absence of sacral vertebra,including associations with lumbar abnormalities (n =2) and sacral agenesis (n =2).One case presented with fourth/fifth lumbar vertebra bone fusion and fifth lumbar/first sacral vertebra bone fusion.On radiology,4 cases had concurrent scoliosis.None of them had tethered cord,diastematomyelia or meningocele.The understanding of sacral agenesis may be improved after reviewing and summarizing clinical features and radiological findings.
