Objective To explore the influence of psycho-behavioral intervention on psychological status and quality of life in patients with gastroesophageal reflux disease (GERD). Methods 62 patients with GERD were divided into intervention group (n=30) and control group (n=32). Both groups received routine treatment, and the intervention group received psychological care applying cognitive, emotional,behavioral, social support intervention in addition. They were assessed with Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS), and Generic Quality of Life Inventory (GQOLI) before and 6 weeks after intervention. Results The scores of SAS, SDS, and GQOLI (all the dimensions and total) improved in the intervention group compared with the control group after intervention (P<0.05). Conclusion Psycho-behavioral intervention can reduce the anxiety and depression, and improve the quality of life for patients with GERD.

Objective To investigate the effect and mechanism of the icaritin on the human cronic myeloid leukemia K562 cells. Methods The K562 cells at logarithmic growth phase were divided into the control group and the icaritin group. The cells in the control group were normally treated and the cells in the icaritin group were incubated with 8 μmol/L icaritin. Methyl thiazolyl tetrazolium (MTT) method and flow cytometry were used to examine the proliferation and apoptotic changes in the two groups after incubation for 72 h, respectively. Gene expression of p85 and Akt were detected by RT-PCR. The protein changes of p85, Akt, p-p85, p-Akt cleavage-caspase-3 and caspase-3 were detected by Western blot. Results Compared with the control group, the proliferation rate of K562 cells in the icaritin group was significantly decreased (P<0.05), however the apoptotic rate of K562 cells and the expressions of p-p85, p-Akt, cleavage-caspase-3 in the icaritin group were significantly increased (all P< 0.05), but the expressions of p85 mRNA, Akt mRNA and caspase-3 protein had no difference (all P> 0.05). Conclusion Icaritin could induce the proliferation and promote the apoptosis of K562 cell, and its mechanism may be achieved through activating the PI3K-Akt signal transduction pathway.

OBJECTIVE To look into and analyze the application of antibacterial used in our hospital in order to enhance the rationality of clinical usage. METHODS We conducted the survey by means of picking out examples in numbers within a definite range,looking back at the records with regard to it from Jan 2004 to Dec 2004. RESULTS Altogether there were 5 302 medical records.The percentage of using antibacterial was 70.24%,from which 45.22-36.68% were used two kinds and 8.54% were used more than two kinds.As to the basis,preventive use taken up a large proportion,accounted for 48.93%;the main route was by intravenous injection,which added up to 74.03%.Of the antibacterials applied,the first three were penicillins;aminoglycosides;cephalosporins.The percentage for surgical application was 94.49%,from them 57.14% used 2 or more kinds for treatment of incision of type Ⅰ. CONCLUSIONS It is very necessary and urgent to supervise the management of the rational application of antibacterial.

Objective To evaluate the diagnosis and treatment of left renal vein entrapment syndrome. Methods The clinical data of 10 cases of left renal vein entrapment syndrome were retrospectively analyzed.Their mean age was 24 years (range,14-37 years).Of them 7 cases presented with non-glomerular origin hematuria;2,with orthostatic proteinuria;1 with hematuria accompanied by proteinuria.Color Doppler sonography showed that the dilated segment of the left vein was three-fold than the strictured segment in diameter,and magnetic resonance angiography (MRA) showed that the left renal vein was compressed in 9 cases. Results Stent placement across the left renal vein was performed in 7 cases.Superior mesenteric arteriectomy and replantation were performed in 3 cases.The operations were all successful.Follow-up of 1-5 years showed that the clinical symptoms were improved and urine tests were normal. Conclusions Non-glomerular hematuria or orthostatic proteinuria is frequently found in left renal vein entrapment syndrome.Left renal vein entrapment syndrome can be diagnosed by Doppler sonography,MRA and cystoscopy in the presence of hematuria or proteinuria.Generally,conservative treatment and careful follow-up are conducted in these patients.Surgical and radiologic interventional procedures are effective alternatives for those with glomerular dysfunction and complications.
