Objective:To investigate the feasibility,moderate-and short-term efficacies of laparoscopic surgery in the resection of the gastric gastrointestinal stromal tumors(GIST)with the tumor diameter more than 5 cm.Methods:The clinicopathological data of 26 gastric GIST patients with the diameter more than 5 cm underwent laparoscopic complete resection were retrospectively analyzed.The postoperative recovery,complications and moderate-and short-term prognosis of the patients were observed.Results:All the patients underwent laparoscopic surgery resection without open operation.According to the location and growth types of tumors,the total gastrectomy was performed in 1 case,the approximal gastrectomy was performed in 2 cases,the distal gastrectomy was performed in 2 cases,and the gastric local resection was performed in the rest 20 cases.The mean diameter of tumors was (5.94±1.28) cm,the mean operational time was (84.23±27.02) min,and the mean blood loss was (72.38±34.24) mL.The postoperative recovery time of bowel function was (2.77±0.65)d and the mean length of postoperative hospitalization time was (7.04±2.24) d.There was 1 case of intraperitoneal hemorrhage and 1 case of anastomotic stenosis;they recovered after conservative therapy.The postoperative pathology results(according to the modified NIH standard) indicated the number of moderate-risk patients was 18(69.23%),and the number of high-risk patients was 8(30.77%).A total of 12 cases accepted the adjuvant therapy with imatinib.There was 1 case of hepatic multimetastasis,and there was no local recurrence or death in the other patients.Conclusion:The moderate-and short-term efficacies of laparoscopic surgery in the gastric GIST patients with the tumor diameter more than 5 cm is safe and feasible.

Objective To sift out the optimized electric pulse parameters for electroacupuncture treatment for lower limb myatrophy and explore the mechanism of its treatment.Method A model of lower limb myatrophy was made in 40 SD rats.The rats were then randomized to groups A (model group without electroacupuncture), B (a pulse duration of 0.5 ms and a frequency of 2 Hz), C (a pulse duration of 200 msand a frequency of 2 Hz) and D (a pulse duration of 200 ms and a frequency of 1/2/3 Hz).Points Zusanli(ST36)and Chengshan(BL57)were given electroacupuncture for four courses of treatment.Thesciaticfunction index (SFI),gastrocnemius muscle wet weight ratio (GW), gastrocnemius muscle fiber cross-sectional area ratio (GC),gastrocnemius muscle cell diameter ratio (GD)and gastrocnemius muscle cell apoptosis index (AI)were determined.Result SFI, GW and GC increased significantly and AI decreased significantly in groups C and D compared with group A (P<0.05). AI decreased significantly in groups C and D compared with group B (P<0.05). AI decreased significantly in groups D compared with group C (P<0.05). Conclusion Apulse duration of 200 ms and a frequency of 1/2/3 Hz are the optimizedelectric pulse parametersfor electroacupuncture delaying myatrophy.Its mechanism is related to inhibiting myocyte apoptosis.

Objective To evaluate the therapeutic effects and side effects of MMF on severe SLE patients compared with CTX.Method All 106 severe SLE patients were randomly allocated to 2 groups:MMF treatment group (53 patients):1 5 g/d for 3 months,1 0 g/d for following 3 months,and then 0 5~0 75 g/d;IVCTX treatment group:0 75 g/m 2 per month for 6~12 months.Prednisone was used in all patients.Clinical and laboratory parameters including SLE DAI,Hb,platelet,urine protein,albumin,SCr,aCL,ANA and anti dsDNA were observed.Results After 3 month treatment,all clinical and laboratory parameters were significantly improved in MMF group,while only partial parameters were improved in CTX group.Hb and platelet increased and urine protein and anti dsDNA decreased faster in MMF group than in CTX group.At month 6 the clinical and laboratory parameters improved significantly in both groups ( P

Objective: To investigate the expression and identification of CH50 polypeptide in bladder cancer cell line BIU-87 by gene transfection. Methods:The eukaryotic expressing vector pCH510 of polypeptide CH50 was introduced into BIU-87 cells by gene transfection Lipofectimine TM2000.The expressed product was identified by immunohistochemistry and Western blot method. The expression of the transfected gene was identified by RT-PCR. Results:The BIU-87 cells could produce CH50 polypeptide by transfection. Conclusion:When the vector of pCH510 was transfected into BIU-87 cells in vitro, the cell adhension characteristic would be changed.

The traditional denoising algorithm for ultrasound images would lost a lot of details and weak edge information when suppressing speckle noise. A new denoising algorithm of adaptive threshold based on curvelet transform is proposed in this paper. The algorithm utilizes differences of coefficients' local variance between texture and smooth region in each layer of ultrasound image to define fuzzy regions and membership functions. In the end, using the adaptive threshold that determine by the membership function to denoise the ultrasound image. The experimental text shows that the algorithm can reduce the speckle noise effectively and retain the detail information of original image at the same time, thus it can greatly enhance the performance of B ultrasound instrument.

Objective Although heart transplantation surgery has become more common,little is known about the psychological status of patients waiting for a heart transplant.Method Ninety-three patients registered for heart transplantation from March 2013 to March 2014 in a large general hospital in Shanghai were assessed by a psychiatrist using the Hamilton Depression Scale (17 items) and the Hamilton Anxiety Scale.Out of them 36 were preoperatively admitted to the Cardiac Surgery Department.The scales were assessed repeatedly at the 1st day,3rd day,7th day,10th day and so on until the operation took place.Result The mean scores of HAMD and HAMA of 93 patients in the waiting list were separately 13.11 ±3.81 and 14.20±4.57.Among them 18(19.4%) were classified as moderately depressed,31(33.3%) had moderately anxious symptoms,and 14(14.1%) had severe anxious symptoms.Thirty-six patients were preoperatively admitted to hospital.Their mean scores of HAMD and HAMA were separately 13.19-± 3.82 and 16.17 ± 4.35.Among them 7(19.4%) were classified as moderate depression at the time of admission,16 (44.4%) had moderately anxious symptoms and 9 (25.0%) had severe anxious symptoms.The scores of HAMD had significant difference (t =3.383,P =0.002) before and after admission.Paired t test was separately conducted to analyze the first assessment and the 3rd-day assessment of HAMA and HAMD total scores after admission of all the inpatients.The results showed the scores were statistically different (for HAMA,t =2.786,P =0.009; for HAMD,t =14.024,P =0.000).Repeated ANOVA was used to analyze the recipients who had three assessments.The results had statistical difference (for HAMA,F =4.568,P=0.020; for HAMD,F=5.626,P =0.034) and the difference of HAMD score at different time points had a linear trend (F =8.273,P =0.013).Conclusion After hospital admission,the depression symptoms will be significantly alleviated.When waiting for the transplant in the hospital,the anxiety symptoms alleviate slightly in three days and then aggravate significantly.The depression symptoms alleviate slightly continuously.
