Objective To explore the effect of combination application of preoperative carbohydrate loading and sequential enteral nutrition on the recovery of postoperative patients with stomach neoplasm.Methods Ninety-eight patients with stomach neoplasm were randomly divided into three groups.Those were Group A (preoperative fasting + sequential EN,n =33),group B (preoperative carbohydrate loading + postoperative TPN,n =33) and group C (preoperative carbohydrate loading + sequential EN,n =32).Insulin sensitivity (IS) ; Nutritional indicators including pre-albumin (PA) and transferrin (TRF) ; immunity parameters including IgG,IgM and IgA were measured in blood on the day before the operation,the 1st day,4th day and 8th day after the operation.Meanwhile,anal exhaust time after the operation,incidence of complications and postoperative hospitalizing time were also observed.Results The level of IS in group C at 4th day and 8th day after operation were 35.8 ± 3.2 and 36.1 ± 3.5,higher than those in A group and B group (A group:30.7 ±3.3,33.5 ±2.9;B group:33.7 ±3.1,34.0 ±2.2),and the differences were significant((F =20.88,7.28 ;P ＜0.05).At the 4th day after the operation,the levels of PA in group B and group C were (191 ± 11.6) mg/ and (193 ± 12.7) mg/L,significantly higher than those in group A ((176 ± 14.1) mg/L;F =17.15,P ＜ 0.01).At the 8th day after the operation,the levels of PA and TRF in group C were (221.3 ±30.81) mg/L and (86 ± 0.37) g/L,significantly higher than those in group A and group B (group A:(198.0 ± 30.6) mg/L,(1.60 ± ±0.33) g/L;group B:(202.0 ±28.6) mg/L,(1.61 ±0.34) g/L;F =5.42,5.83 ;P ＜0.01).At the 8th day after the operation,the levels of IgA,IgG and IgM in the group C were (2.74 ±0.69) g/L,(14.55 ±2.57) g/ L,(1.08 ± 0.33) g/L,significantly higher than that in group A and group B (group A:(2.30 ± 0.54) g/L,(12.71 ±2.94) g/L,(0.86 ±0.31) g/L;group B:(2.29 ±0.50) g/L,(12.06 ±3.33) g/L,(0.89 ±0.27)g/L;F =6.12,6.13,4.94;P ＜ 0.05).Conclusion The combination of preoperative carbohydrate loading and sequential enteral nutrition can reduce insulin resistance,improve postoperative nutritional status,improve the recovery of immune function and intestinal function,as well as reduce the incidence of postoperative complications.

Objective To To evaluate the efficacy of Guglielmidetachable coil (GDC)F embolization in treatment of intracranial aneurysms and summarize the main points of GDC manipulation.Methods Thirty two patients were examined with digital substraction angiography (DSA) and 34 intracranial aneurysms were found, including 15 aneurysms in the anterior communication artery, 13 in the posterior communi cation artery, 2 in the middle cerebral a rtery, 1 in the anterior cerebral artery and 1 Ophthalmic artery. After wards GDC was used for embolization therapy. Results Thirty two patients with 34 aneurysms were successfully embolized with GDCs. Complete embolization achieved in 20 patients and incomplete in 12 patients; while one aneurysm ruptured during the performance, but all curedafter treatment. Vas cular spasm occurred in 2 patients, one of them had slight hemiplegia. Sixpatients with 7 aneurysms were followed up by DSA examinationl year after operation. No obvious change was observed.Conclusions Treatment of intracranial aneurysms with GDC embolization is a safe, reliable, and effective measure. Skillful techniques of the operator and correct management of complications are important factors affecting the outcome of operation. A period follow up is essential to patients with partial embolism.

Objective To evaluate the safety and feasibility of Wingspan stent for patients with symptomatic M1 stenosis of middle cerebral artery (MCA). Methods Thirty-two cases with recurrent symptomatic MCA stenosis resistant to medical therapy treated by self-expanding stent were reviewed retrospectively [average (49±19) years old, 13 women]. All patients underwent angioplasty and stenting with the Gateway balloon-Wingspan stent system. After 6 months, all patients were followed up by telephone or clinic, and advised followed up with DSA or TCD. Results Thirty-two patients were successfully stented during the first treatment session. The mean degree of stenosis reduced from (76.5±15.4)% to (19.3±9.2)%. The number of complicating subarachnoid hemorrhage was one, and occlusion occurred on one patients related to balloon angioplasty. During a follow-up of 6 months, there was no recurrence of transient ischemic attack or stroke in 32 available patients. Cerebral hemodynamics using transcranial Doppler monitoring were normal in 19 follow-up patients. Six-month angiographic follow-up was obtained in 5 patients, demonstrating good patency in 5 stenting vessels. The other patients refused to perform TCD or DSA. Conclusions Wingspan stent for symptomatic stenosis of middle cerebral artery appears to be a safe and feasible under strict control of periperformeral project. However further study is needed to evaluate the long-term effect.

Objective To discuss the application of Chaperon guiding catheter system in endovascular treatment of intracranial aneurysms. Methods A total of 20 patients with intracranial aneurysms were enrolled in this study. The patients hadⅡorⅢtype of aortic arch (n=11) or sclerotic plague at the orifice of internal carotid or vertebral artery (n = 9). Endovascular embolization of the intracranial aneurysm was carried out in all patients. By using Cordis guiding catheter system the catheter was placed into the target artery. Chaperon guiding catheter system was used during the procedure in order to determine whether the Chaperon guiding catheter could be smoothly placed into the target artery or not. Results When the Chaperon guiding catheter system was employed in the endovascular procedure, the difficulties of catheterization caused by the distortion of the aorta or by the plagues on the walls of arteries could be basically overcome. The Guiding catheter could be smoothly placed into the target arteries. Conclusion The Chaperon guiding catheter system can be successfully used in the endovascular treatment for the intracranial aneurysms, especially when the patient has tortuous aorta or there is sclerotic plague on the artery wall.

Objective To analyze the plasty of the tip framework and the nasal tip in insufficient-lining cases with auricular and septal cartilage.Methods The tip framework was formed by using septal extension graft (SEG) and columellar strut (CS) to construct the main framework of nasal tip,and then according to the size of the graft the next processes were chosen for supporting structure.When the graft size met the tip position,the caudal margin of the framework could be beyond the maximum stretch position of the lower lateral cartilage and reached or was close to the expected tip position.When the graft size was insufficient,auricular cartilage was used to hold the caudal margin of the framework to extend or to heighten the framework further.Refined plasty of nasal tip was as follows:when the end of framework was higher than or equal to the dome above 3 mm,auricular cartilage strip was used to reconstruct the dome;when less than 3 mm,multilayer onlay grafts were used to heighten the dome.Results From May 2013 to May 2015,42 cases were followed up from 6 months to 18 months.18 cases belonged to the type 1,including 13 cases using ear cartilage to reconstruct dome,5 cases using onlay graft;24 cases belonged to the type 2,including 14 cases using onlay graft and 10 cases using ear cartilage to reconstruct the dome.They all got good results.Conclusions To the insufficient lining cases,the appropriate method can be chosen to form stable tip framework according to the preoperative design and the graft size.Then onlay grafts or dome reconstruction technique is used to form the tip.Most of the insufficient-lining cases can get satisfactory results.

Objective To investigate the value of panel fluorescence in situ hybridization (panel FISH)for detection of genomic aberrations in chronic lymphocytic leukemia(CLL). Methods Five types of fluorescein-labelled DNA probes including five sequence specific probes D13S25 for 13q14. 3, RB1, p53, ATM (11 q23)and centromeric probe for chromosome (CSP12) were used to perform fluorescence in situ hybridization assays in 17 patients with CLL. Its results were compared with that obtain by conventional cytogenetic (CC)examination. Results In 17 patients with CLL, CC examination showed that only one case (1/17) was found to have chromosomal abnormality that was simultaneous trisomies 3,8 and 18, whereas panel FISH assay showed that 10 cases (10/17) were found to have genomic aberrations including deletion of D13S25 in 4 cases,deletion of ATM in 2 cases,deletion of p53 in 1 case,deletion of D13S25 combined RB1 in 1 case and 1 case with a variety of abnormalities. Conclusions Panel FISH is a useful method for detection of genomic aberration in CLL If it is combined with CC,it can obviously enhance the detection rate of chromosomal abnormalities in CLL.

BACKGROUND: Osteosarcoma is the most common type of bone tumor and generally occurs between the age of 10 to 25; moreover, in clinical practice osteosarcoma is found to occur more often in minority nationalities in Xinjiang Autonomous Region. Do its incidence and prognosis vary between nationalities at gene levelOBJECTIVE: To observe the different expressions of p53, bcl-2 and proliferative cell nucleus antigen (PCNA) gene during the development of osteosarcoma between various Xinjiang nationalities.DESIGN: Non-randomized comparative experiment taking clinical pathological specimens as subjects.SETTING: Immunohistochemical Laboratory, the Pathological Center of Xinjiang Medical University.PARTICIPANTS: Totally 52 pieces of specimen were obtained from excised osteosarcoma tissues in the Pathological Department, the First Affiliated Hospital of Xinjiang Medical University, and the Pathological Department, the First Affiliated Hospital of Shihezi University, between January 1,1984 and December 31, 2001. The 52 cases of osteosarcoma included 29cases derived from male patients and 23 from female patients; among them there were 12 cases of Kazak minority, 17 cases of Uygur minority and 23cases of Han nationality. Other 32 specimens were obtained from 32 patients with tumor-like lesions (such as osteofibrous dysplasia or fibrous dysplasia), including 7 cases of Kazak minority, 11 cases of Uygur minority,and 14 cases of Han nationality. The informed consent was obtained from the patients.METHODS: This experiment was carried out at the Immunohistochemical Laboratory, the Pathological Center of Xinjiang Medical University. LSAB method was used to detect p53, bcl-2 and PCNA expression in the two groups. The first antibody was re placed by PBS as blank control, and the available positive expression was taken as positive control. P53 protein and PCNA were observed to express in cell nucleus, appearing obvious redbrown granules with positive expression, whereas Bcl-2 protein was expressed in cytoplasm.lationship between the expression of Bcl-2, p53 and PCNA in osteosarcoma.of different nationalities: The expression of p53, bcl-2 and PCNA in Kazak minority, Uygur minority and Han nationality was not remarkable p53, bcl-2 and PCNA in osteosarcoma and bone tumor-like lesions: The expression of P53, Bcl-2 protein and PCNA in osteosarcoma was remarkably higher than that in tumor-like lesions (42.31% vs. 3.13 %, 59.62%sion of bcl-2, p53 and PCNA in osteosarcoma: There was a close correlation between bcl-2 and p53, as well as between bcl-2 and PCNA in osteosarcoma tissues (X2 =5.818 2, 4.900 0, P＜0.05).CONCLUSION: The results indicate that there was no statistical difference between various nationalities in the expression of p53, bcl-2 and PCNA, as well as osteosarcoma differentiation. Suggesting that these genes may share the common regulation during the development of osteosarcoma,which is less associated with their nationality-related hereditary background.

Objective To study the impacts of berberine on the growth, migration and radiosensitivity in human breast cancer cells.Methods MTT assay was used to evaluate cell growth.In vitro scratch migration assay was used to determine cell migration.Annexin V assay was used to detect cell apoptosis.The distribution of cell cycle was evaluated by flow cytometry assay.Colony formation assay was used to detect the influence of berberine on cell radiosensitivity. Western blot assay was employed to measure protein expression.Results Berberine inhibited cell growth and migration in two human breast cancer cell lines, MCF-7 and MDA-MB-231, in a dose-and time-dependent manner. Furthermore,berberine resulted in a cell cycle G0/G1 arrest.Compared with control,the early apoptosis in MDA-MB-231 and MCF-7 cells treated with 40 pμmol/L of berberine was as high as 86.6％ and 66.6％ (t =8.79,10.32,P ＜ 0.01 ),respectively. Berberine caused a dose-dependent increase in Bax and Caspase-3 protein expressions,but did not change Cyclin D1 protein expression,while suppressed the expressions of Cyclin B1 and Bcl-2 protein. As analyzed with multi-target click model fitting curves,the SERD0 of berberine-treated cells were 1.12 and 1.22 for MDA-MB-231 and MCF-7cells respectively at the dose D0 of X-rays.Conclusions The berberine inhibited the growth and migration of breast cancer cells via apoptosis induction and cell cycle arrest.Moreover,berberine increases cell sensitivity to X-ray irradiation.
