Objective To investigate the relation of vascular endothelial growth factor (VEGF) and angiogenesis to the progression of colorectal carcinoma (CC). Methods VEGF protein expression and microvessel density (MVD) in 102 cases of human CC were examined by use of immunohistochemical staining. MVD and VEGF expression were analysed with their relation to histological grade, depth of invasion, Dukes stage, lymph node metastasis, liver metastasis and prognosis of CC. Results MVD was significantly higher in VEGF positive CC than in VEGF negative CC ( P

ObjectiveTo determine the prognostic value of angiogenesis in non-metastatic colorectal carcinoma at the time of laparotomy.Methods Microvessel counts(MVC) of 58 specimens were investigated by immunohistological staining with a monoclonal antibody against F-Ⅷ RAg. Correlation between MVC, clinicopathologic factors, postoperative local recurrence, and liver metastasis was evaluated.Results MVC correlated positively with postoperative local recurrence(P21, the risk of liver metastasis and local recurrence significantly increased. MVC also correlated with prognosis (P

Objective To explore the effect of preemptive anti-cytomegalovirus therapy on prognosis of patients with acquired immunodeficiency syndrome (AIDS) and cytomegalovirus (CMV) viraemia.Methods A non-random prospective study of male hospitalized patients were carried out who were newly diagnosed as AIDS during July 1,2011 to June 30,2013 in the First Affiliated Hospital of China Medical University.There were 69 patients who were divided into treatment group (57 cases) and control group (12cases).The duration of anti-cytomegalovirus therapy was a week after plasma CMV-DNA becoming undetectable.Baseline age,CMV-DNA,human immunodeficiency virus (HIV)-RNA,CD4+T cells,the rate of pneumocystis carinii pneumonia (PCP) and tuberculosis were evaluated between two groups.After 12-month follow-up,CD4 + T cells,the rate of rehospitalization,CMV retinitis,and mortality were evaluated.Results There were no difference in CMV-DNA,HIV-RNA,CD4 + T cells,the rate of PCP,and tuberculosis(P > 0.05).At the end of 12 months,there were higher CD4 +T cells and lower rehospitalization rate in treatment group than control group(t =-3.850,P < 0.05;x2 =6.078,P < 0.05).CMV retinitis was not found.The mortality was not different between two groups(P >0.05).Conclusions Anticytomegalovirus therapy was beneficial to the increment of CD4 +T cells and decrement of rehospitalization,and prevention from CMV retinitis.

Objective To investigate the value of perfusion CT in the evaluation of neoadjuvant chemotherapy in locally advanced squamous cell carcinoma.Methods Sixty-seven patients with Ib2-IIb squamous cell carcinoma of the cervix underwent CT perfusion imaging before neoadjuvant chemotherapy to measure blood flow (BF),blood volume (BV),peak time (MTT),permeability sur-face (PMB),perfusion time to peak (TTP)and MIP(HU);and underwent routine enhancement CT after the two course of neoadju-vant chemotherapy treatment to measure tumor size,and evaluate the therapeutic effect.Results Among 67 patients,48 patents were effective (2 completely remission and 46 partial remission),and 1 9 patients were ineffective (1 5 stable and 4 progressed),with the overall response rate of 71.6%.The differences of PMB and BV value between effective and ineffective group were statistically significant before neoadjuvant chemotherapy (P <0.001).The BF,MTT,TTP value were no significant difference between effec-tive and ineffective group before neoadjuvant chemotherapy (P >0.05).The BV and PMB value were relatively higher in the patients with effective chemotherapy.Conclusion CT perfusion imaging could measure the BV and PMB value of the tumor before neoadju-vant chemotherapy to provide the basis for treatment selection.

Objective: To evaluate the bioavallability and bioequivalence of rabeprazole sodium enteric-coated pellets capsules. Methods:A randomized crossover design was performed in 32 healthy male volunteers. A single oral dose of 20 mg rabeprazole sodium enteric-coated pellets capsules ( test preparation) or enteric-coated shell capsules ( the reference capsules) was administrated under fed conditions. The wash period was 7 days. The blood samples were collected at different time points. The concentration of rabeprazole in plasma was determined by an LC-MS/MS method. The pharmacokinetic parameters were calculated by DAS 3. 0 software and the bio-equivalence was evaluated. Results:The maln pharmacokinetic parameters of the two formulations were shown as follows:T1/2 of (2. 20 ± 0. 83)h and(1. 951 ± 0. 515)h,Tmax of (3. 88 ± 1. 11)h and(4. 64 ± 1. 504)h,Cmax of (401. 06 ± 170. 75)ng·ml-1 and(394. 63 ± 215.64)ng·ml-1,AUC0→t of (918.42 ±427.39)ng·h·ml-1 and (994.49 ±520.73)ng·h·ml-1, and AUC0→∞ of(937.30 ± 445.13)ng·h·ml-1 and(1 011.69 ±534.77)ng·h·ml-1. The analysis showed that the maln pharmacokinetic parameters of the two formulations had no significant differences(P>0. 05) except for Tmax(P<0. 05). The relative bioavallability of rabeprazole sodium enteric-coated pellets capsules was (99. 80 ± 7. 20) %. Conclusion:Compared with the reference capsules, rabeprazole sodium enter-ic-coated pellets capsules show the property of higher dispersion degree, milder influence from food, more rapid release and absorption. The enteric-coated pellets capsules and the reference capsules are bioequivalence.

Objective To investigate the knowledge,attitude and behavior of medical staffs on foodborne diseases.Methods To investigate the knowledge,attitude and behavior of medical staffs on foodborne diseases by random sampling following the questionnaire.Results There were 332 medical workers attending the survey.The medical staffs were lack of knowledge for foodborne disease,percent of pass was 34.33%.The pass rate of attitude and behavior were 88.88% and 98.19%.The knowledge score of medical staff of top three hospital (6.49± 2.18)were lower than the community health service center(7.04±2.26) (P<0.05),but attitude and behavior score of this two staffs had not statistical differences(P>0.05).Conclusion It is necessary to help medical staff to improve the attitude of foodborne diseases,and improve the monitoring of underreporting case.
