Objective To study the significance on dynamic changes of serum vascular endothelial growth factor( VECF) and matrix metalloproteinase 9( MMP-9) in patients with acute cerebral infarction. Methods 123 patients with acute cerebral infarction were selected as research object, and they were the observation group, and 80 healthy peoples at the same time were selected as control group. Then the serum VEGF and MMP-9 in patients with acute cerebral infarction after pathogenesis at first,third,fifth,seventh and fourteenth day were detected,and the correction between the levels and infarct size,prognosis were studied. Results The serum VECF and MMP-9 of observation group compared with those of control group,the change showed increased first and decreased afterwards,but the levels were all higher than those of control group (P ＜ 0.01). There were correction between the levels and infarct size, prognosis.The serum VEGF[(369.3 ± 108.7,476.2 ± 118.4,551.5 ± 144.5,661.7 ± 164.6,437.6 ± 123.9)ng/L]and MMP-9[(333.8±101.4,459.7±119.9,370.3 ±119.5,320.5 ± 129.1,255.4 ± 101.6)ng/L] in poor prognosis patients after pathogenesis at first,third,fifth,seventh and fourteenth day were all higher than those of good prognosis patients ( P ＜0.01). Conclusion The serum VEGF and MMP-9 in patients with acute cerebral infarction showed dynamic change,and there was close relationship between the levels and infarct size.

Microglia is the principal immune effector cell in brain. It plays some important roles in support, nutrition, protection, and repair in the physiological activities of neuron. Microglia can be quickly activated, which may proliferate after cerebral ischemia, and promote phagocytosis of macrophage. It exerts dual effects by producing neurotoxic molecules and neurotrophic factors. Therefore, to study the relationship between microglia and cerebral ischemia, give full play to its protective functions and reduce its damage will help to improve the therapeutic effects of cerebral ischemic injury.

BACKGROUND: Common complication of traditional joint replacement is hip joint dislocation and large head joint implant can effectively solve this problem. OBJECTIVE: To investigate the preliminary efficacy of large head metal-on-metal implants for patients undergoing total hip arthroplasty. DESIGN, TIME AND SETTING: Prospective cohort study. The patients were selected from Department of Joint Surgery, Xinjiang Hospital of Traditional Chinese Medicine between February 2007 and January 2008. PARTICIPANTS: A total of 65 patients (71 hips) undergoing large head metal-on-metal implantation in Xinjiang Hospital of Traditional Chinese Medicine were selected, including 21 females and 44 males with an average age of 54.6 years (ranging 19 to 77 years). Of them, there were 28 cases of necrosis of the femoral head, 24 of hip osteoarthritis, 9 of femoral neck fracture and 4 of acetabular dysplasia. METHODS: According to age, sex, cause of disease and preoperative joint function, the patients were divided into traditional prosthesis (n=30, 33 hips, metal-on-polyethylene implant) and large head M-O-M group (n=35, 38 hips, ASR/XL prosthesis, DePuy, Motech, Warsaw, IN, USA). MAIN OUTCOME MEASURES: The pre and postoperative Harris scores for the hip, range of motion, periprosthetic radiolucency, leg-length inequality and complications were recorded and compared. RESULTS: All patients were followed-up. The traditional group was followed up for 20 months (ranging 13-28 months), and the large head M-O-M group was followed up for 17 months (ranging 10-26 months). The mean Harris score was 89 points (ranging 59-98) in traditional group, and 94 points (ranging 71-100) in large head M-O-M group (P=0.014). The range of motion of hip was improved, and the large head M-O-M group (34?) was superior to traditional group (26?, P=0.004) at 6 months after surgery; the range of motion was improved 27? in traditional group and 37? in large head M-O-M group (P=0.009) over 1 year of follow up. The leg-length inequality was 4 mm (2-11 mm) in large head M-O-M group and 7 mm (5-16 mm) in traditional group (P=0.005). Both groups exhibited periprosthetic radiolucency (≤1 mm, 2 cases in traditional group and 3 cases in large head M-O-M group). One patient in the traditional group suffered dislocation. CONCLUSION: The large head M-on-M implants in total hip arthroplasty has excellent short-term effects on patients compared with traditional prosthesis. They offer the more stability and better restoration of hip articulation function and biomechanical reconstruction.

Objective To investigate the feasibility and safety of hand assisted laparoscopic total gastrectomy with D2 lymphadenectomy for advanced cardiac cancer compared with open surgery.Methods 174 patients suffering cardiac,upper,middle or whole gastric cancer operated in our department from October 2013 to October 2014 were divided into open surgery group and laparoscopic group.Perioperative parameters were compared between the two groups.Results Patients in loparoscopic group were associated with significantly less operative blood loss [(110 ± 17) ml vs.(345 ± 95) ml,t =4.95,P =0.011],and shorter postoperative hospital stay [(8.7 ± 0.6) d vs.(14.3 ± 2.1) d,t =0.26,P =0.031],but longer operative time [(295 ± 37) min vs.(215 ± 23) min,t =3.78,P =0.004],compared with that of open surgery.There was no significant difference in the numbers of lymph node dissection between the two groups.Esophagus resection length in open group was (4.0 ± 1.2) cm,and that was (4.1 ±1.0)cm in laparoscopic group (t =0.95,P =0.147).Two patients in open group had positive margins and underwent thoracoabdominal resection.There was no difference in major complications between the two groups.Conclusion Hand assisted laparoscopic total gastrectomy for advanced cardiac carcinoma is a safe,feasible,and oncologically sound procedure compared to open procedure.

Objective To evaluate the feasibility and safety of hand assisted laparoscopic total gastrectomy for gastric cancer by two different operative approaches.Methods 191 patients of proximal or gastric corpus cancer operated at our department from Jan 2015 to Dec 2017 were divided into two groups:by outer omental bursa approach group (OBA) and through inner omental bursa approach group (IBA).Operative time,estimated blood loss,number of lymph node retrieval,times of analgesic injection,time to the first flatus and postoperative hospital stay were compared between the two groups.Results Estimated blood loss,times of analgesic injection,time to the first flatus and postoperative hospital stay were not statistically different between the two groups.The operative time was significantly shorter in the IBA than the OBA.There were no significant differences in tumor size,retrieved lymph nodes,AJCC/UICC staging and resection margins between the two groups.Conclusion Hand assisted laparoscopic total gastrectomy by the outer omental bursa approach is technically feasible and safe,and allows for adequate lymphadenectomy.

Objective To prospectively investigate the value of urinary neutrophil gelatinase-associated lipocalin (NGAL) in the diagnosis of acute kidney injury (AKI) following adult cardiac surgery. Methods Twenty-nine hospitalization patients undergone cardiac surgery were enrolled in the study. Serial blood and urinary samples were collected immediately before incision and at various time intervals after surgery. The primary outcome measure was acute kidney injury, defined as a 50% increase in the level of serum creatinine (Scr) from baseline. Results Fourteen of 29 developed acute kidney injury. The diagnosis time point with Ser was at 24 (10, 48) h after cardiac surgery. By contrast, the concentration of urinary NGAL rose from a median of 3.42(1.60, 9.92) μg/L at baseline to 20.51(13.42, 50.02) μg/L at admission to ICU (P=0.006),and the median concentration of urinary NGAL in patients who developed AKI was significantly higher at admission to ICU compared with patients who did not develop AKI [20.51 (13.42, 50.02) μg/L vs 2.91 (0.72,8.61) μg/L, P=0.002]. As to urinary NGAL at admission to ICU, the area under the receiver-operating characteristic (ROC) curve was 0.824, the sensitivity was 85.7% and the specificity was 80.0% with a cutoff value of 10.95 μg/L. Significant correlation was found between urinary NGAL at admission and the levd of Scr at 24 h in ICU (r=0.545, P=0.002), as well as estimated GFR (r=-0.546,P=0.002). Conclusion Urinary NGAL concentration is significantly higher in patients developing postoperative AKI at the early time of admission to ICU, which may be a useful early biomarker of AKI after adult cardiac surgery.
