Objective To investigate the efficacy of proton pump inhibitors (PPI) combined with flupethixol melitracen in the treatment of non-erosive gastroesophageal reflux disease (NERD) with anxiety and depression.Methods Fifty six NERD patients with anxiety and depression were evenly divided into the positive treatment group and positive control group.Thirty NERD patients without anxiety and depression were set as negative control group.Both flupethixol melitracen (20 mg per day after breakfast) and PPI esomeprazole magnesium (20 mg per day,20 minutes before breakfast) were administrated in positive treatment group.Only esomeprazole magnesium was given in positive control group and negative control group and the dosage was same as that of positive treatment group.The treatment course of three groups was eight weeks.Before and after the treatment,the symptoms of patients were scored according to gastroesophageal reflux disease questionnaire (GERDQ),Hamilton anxiety scale (HAMA),Hamilton depression scale (HAMD) and Pittsburgh sleep quality index (PSQI).Adverse effects were also observed.Variance analysis was performed for the comparison among three groups.Variance analysis or Post-hoc analysis were used for comparison between two groups.Results The differences of different score value before and after treatment of three groups were statistically significant in total score of GERD Q,score of type A,score of type C,score of HAMA,score of HAMD and PSQI (F=6.32,3.93,5.63,49.61,78.69 and 7.07,all P＜ 0.05).The differences of the score value before and after treatment of positive treatment group in total score of GERD Q,score of type A,score of type C,score of HAMA,score of HAMD and PSQI (4.24±2.05,3.16±1.46,1(0,3),9.32±3.21 and 8.88±2.92) were all higher than those of positive control group (2.38±2.22,1.68±1.33,0(0,2),3.72±2.95 and 3.84±1.97) and negative control group (2.32±2.18,2.48±1.34,0(0,1),2.36±1.25 and 2.36±0.79).And the differences were statistically significant (positive treatment group vs positive control group:Post-hoc analysis,P=0.002,0.022,0.003,0.002 and 0.002; positive treatment group vs negative control group:Post-hoc analysis,P=0.001,0.021,0.004,0.001 and 0.001).The difference of the score value before and after treatment of positive treatment group in PSQI (4 (2,6)) was higher than that of negative control group (2 (1,3),Post-hoc analysis,P=0.001).Two cases of positive treatment group had mild dizziness and the symptom relieved after three to four days.Conclusions For NERD patients with anxiety and depression,anti-depression drug flupenthixol melitracen can be used and the effect is superior to using PPI alone.

Objective: To investigate the clinical efficacy of acupuncture combined with tuina in treating patients with cervical vertigo. ＜br> Methods: According to the principle of randomization, 258 cases with cervical vertigo who met the inclusion criteria for the study were randomly divided into an observation group and a control group, with 129 cases in each. The patients in the observation group received acupuncture combined with tuina therapy, while those in the control group were just treated by the same acupuncture therapy as in the observation group. After 10-day continuous treatments, the clinical efficacies of the two groups were analyzed and compared. ＜br> Results: The total effective rate of the observation group was 100%, versus 86.0% of the control group, and the difference was significant (P＜0.05). After treatment, cervical range of motion (ROM) scores in both groups were statistically significantly different from those before treatment (allP＜0.05); in addition, there was a statistically significant difference in inter-group comparison of ROM score (P＜0.05). ＜br> Conclusion: Compared with simple acupuncture treatment, acupuncture combined with tuina therapy has a better effect in improving the ROM of cervical vertigo patients, with higher clinical efficacy.

Objective To explore the diagnostic value of 18F-FDG PET/CT delayed imaging after induced diuresis for primary bladder tumor.Methods Fourteen patients (12 males,2 females; age range 35-88 years) with pathologically confirmed primary bladder tumor (clinical stage T1.3N0M0) were retrospectively analyzed.All patients underwent standard 18F-FDG PET/CT followed by a delayed (2.5-3.0 h later)pelvic imaging post intravenous injection of 20 mg furosemide and oral intake of 600 ml water.A positivelesion was defined as the uptake of 18F-FDG greater than the urine radioactivity and negative as equaled to or less than the urine radioactivity.Diagnostic efficacy of 18F-FDG PET/CT was calculated with pathology as the gold standard.Mann-Whitney u test was used to analyze data.Results There were 12 malignant (11 urothelium carcinomas and 1 squamous cell carcinoma) and 2 benign tumors (papillary epitheliomas).On standard PET/CT imaging,3 of 12 malignant lesions showed increased metabolism of 18F-FDG and the other 9 were false negative; while the 2 benign tumors showed no abnormal 18F-FDG uptake.The sensitivity,specificity,and accuracy of 18F-FDG PET/CT were 3/12,2/2 and 5/14,respectively.Sizes of the 3 18F-FDG-avid malignant lesions were greater than those of other 9 18F-FDG-negative lesions (26,30,35 mm vs (15.6±6.3) mm; Z=-2.315,P＜0.05).The sensitivity,specificity,and accuracy of delayed pelvic imaging were 11/12,2/2,13/14,respectively.Conclusion 18F-FDG PET/CT delayed imaging after diuresis has a high diagnostic efficacy for primary bladder tumor.

Objective To explore the diagnostic value of delayed 18 F?FDG PET/CT pelvic imaging after forced diuresis in detecting male patients with locally recurrent rectal cancer. Methods Thirty?two male patients ( 32-79 years) with clinically suspicious recurrences of rectal cancer were retrospectively ana?lyzed. All patients underwent a standard 18 F?FDG PET/CT followed by a delayed pelvic imaging after 2.5 h of administration of 20 mg furosemide intravenously and extra water intake of 500 ml at least. Final diagnosis was made by pathology or clinical follow?up (>10 months ) . Diagnostic efficiency of 18 F?FDG PET/CT standard and delayed pelvic images were calculated and compared. χ2 test was used for data analysis. Re?sults A total of 25 patients were diagnosed with recurrent rectal cancer, including 10 cases with invasion of surrounding tissue, and 5 cases with metastases. Among the 7 patients without local recurrences, 2 had dis?tant metastases. The sensitivity, specificity, and accuracy of standard FDG PET/CT were 92.0%(23/25), 3/7, 81.2%(26/32), respectively. The corresponding values of the delayed imaging were 96.0%(24/25), 6/7, and 93.8%(30/32), respectively. The specificity of delayed imaging was higher than that of standard FDG PET/CT (χ2=14.333, P<0.05) , but no significant differences were found in sensitivity and accuracy between the delalyed imaging and standard FDG PET/CT (χ2=0.085 and 0.966, both P>0.05) . The urina?ry bladder activity reached or approached the background during the delayed imaging. Twenty?two malignant lesions of surrounding invasion were confirmed. The positive rate of delayed imaging was higher than that of standard FDG PET/CT:95.5%(21/22) vs 63.6%(14/22);χ2=6.400, P<0.05. Conclusions 18F?FDG PET/CT delayed pelvic imaging after diuresis and hydration is useful for eliminating the artifacts from urina?ry bladder activity, and for detecting the invasion to the rectal surrounding tissue more effectively. It could be a supplement to standard FDG PET/CT.

Objective:To explore the mechanism of the cytotoxicity of human NK cells induced by atorvastatin to colon cancer cell lines. Methods:After colon cancer cells (HCT-116,SW-480,Caco-2) were cultured with different concentrations of atorvastatin, CCK-8 assay was used to assess the effect of atorvastatin on growth of colon cancer cells. The amplification of human NK cells was induced by SCGM medium in vitro. Automatic biochemical analyzer was applied to test the cytotoxicity of NK cells to colon cancer cells which cultured with different concentration of atorvastatin. FCM was used to detect the expression rate of MICA/B on the cells. Results:(1) The cultivation of NK cells:The proportion of NK cells attained to 93. 1% from 4. 5% after cultured for 10 days. (2) The effects of atorvastatin on the growth of the colon cancer cells:After cultured with atorvastatin,the inhibition rate of HCT-116 cells was higher than that in control when the density of atorvastatin increased from 5 μmol/L to 40 μmol/L after 48 h and from 1. 25 μmol/L to 40 μmol/L after 96 h ( P<0. 05 ) . Correlation analysis showed that the concentration of atorvastatin and the growth inhibition rate of HCT-116 cells were positively correlated(r[48 h]=0. 13,r[96 h]=0. 22,P<0. 05). (3) The cytotoxicity of NK cells to colon cancer cells effected after atorvastatin: In different atorvastatin concentrations groups,the cytotoxicity of NK cells to three colon cancer cell lines was all higher than that in control ( P<0. 05 ) . The atorvastatin concentration was from 2. 5 μmol/L to 10 μmol/L for HCT-116 cells,from 5 μmol/L to 20μmol/L for SW-480 cells,and from 2. 5μmol/L to 20μmol/L for Caco-2 cells. Among the three cell lines, the cytotoxicity of NK cells to HCT116 was the highest in the same concentration. (4)NK cells by atorvastatin cutting statins 96 h,the concentration of 20 mmol/L and 40 mmol/L inhibition rate was higher than that of control group,more than other groups on NK cell growth without significant effect. ( 5 ) The impact of atorvastatin on MICA/B expression of colon cancer cells: After cultured with different concentrations of atorvastatin,the expression of MICA/B on colon cancer cells was higher than that in control(P<0. 05). The concentration was 2. 5μmol/L and 5μmol/L for HCT-116 cells,10μmol/L and 20μmol/L for SW-480 cells,and from 2. 5μmol/L to 40 μmol/L for Caco-2 cells. Conclusion:Atorvastatin could inhibit the growth of colon cancer cells (HCT-116,SW-480 and Caco-2) in a dose-dependent manner;and it could enhance the cytotoxicity of NK cells to colon cancer cells;it also could promote the expression of MICA/B of colon cancer cells,and improve the immunogenicity of colon cancer cells.

HBV can interact with alcohol in various ways to cause liver damage. Heavy drinking can accelerate the progression of chronic hepatitis B and lead to a poorer prognosis; meanwhile, it can also affect the outcome and compliance in patients receiving antiviral therapy. The epidemiology of drinking in patients with chronic hepatitis B in China remains unclear, and further studies are needed to clarify the mechanism of interaction between alcohol and HBV. Drinking management should be strengthened in patients with chronic hepatitis B in clinical practice, in order to alleviate liver injury induced by alcohol.

OBJECTIVETo study the quantity of anti-R7V in individuals infected with HIV and AIDS patients and its relation with the progression of disease.

METHODSELISA and precipitation and other methods were used to investigate the quantity of anti-R7V in asymptomatic long-term survivors and AIDS patients.

RESULTSPositive rate and quantity of anti-R7V were higher in the HIV active ones and AIDS. It showed that the quantity and positive rate of anti-R7V were rather high in dissolving test.

CONCLUSIONSIt is strong suggestion for anti-R7V to obstruct the replication of virus by interfering the connection between HIV with CCR5 or CXCR4 and so it impossible HIV entering to CD4+ T cells.
