Objective To achieve the software automatic updates and maintenance in the local area network which is developed based on the C/S structure. Methods Based on the existing software and hardware development platform,we use PowerBuilder to exploit and compile a program which can determine whether the software need to update automatically or not under the premise of unchanging the existing LAN software system. Results When the user terminal in the local area network runs this program,they can update it automatically whenever they need. Conclusion This method will greatly reduce the later maintenance software,upgrade works and also improve the work efficiency and accuracy.

Objective To investigate the in vivo effects of glutamine(Gln) on inflammatory cytokine release in murine peritoneal macrophages during sepsis. Methods Sixty Kunming mice were randomly divided into sham-operation group(Sham group,n=20),operation control group(Con group,n=20) and Gln-treatment group(Gln group,n=20).Sepsis was induced by cecal ligation and puncture in Gln group and Con group,and Gln(0.75 g/kg) or saline was immediately administered via single tail vein injection.Serum was collected and macrophages were harvested from peritoneal lavage at 6 h in these three groups.Intracellular and serum cytokines of tumor necrosis factor-?(TNF-?),interleukin(IL)-6 and IL-10 were detected by ELISA.The expression of TNF-? mRNA in macrophages was analyzed by RT-PCR,and the expression of heat shock protein(HSP) 72 in macrophages was evaluated by Western blotting. Results Gln group demonstrated significantly lower intracellular TNF-? and IL-6 levels than Con group(P0.05).The serum TNF-? level was significantly lower in Gln group than in Con group(P

Objective To explore the reason for remedy radical operation after endoscopic submucosal dissection (ESD) for early gastric cancer.Methods The clinical data of 26 early gastric cancer cases who received remedy radical gastrectomy after ESD between January 2012 to March 2015 in Nanjing Drum Tower Hospital were analyzed retrospectively.Results All cases were followed up and mid follow-up was 25 months.There was no death nor tumor reccurence cases during the follow-up.Three cases suffered from complications in radical surgery for gastric cancer including afferent jejunal loop obstruction,adhesive intestinal obstruction,stomach paralysis respectively,all were cured by conservative therapy.Postoperative pathology found lymph node metastasis in 3 cases.Conclusions En bloc resection and negative resection margin,as well as free lymphatic metastasis are two important factors determing the survival of early gastric cancer patients undergoing ESD treatment.

The clinical, neuroelectrophysiological, neuropathological characteristics and outcome of a case of acute sensory axonopathy are reported. The patient was a 32-year-old female. She presented with acute onset sensory abnormalities, sensory ataxia, pseudoathetosis and areflex. Lab testing showed cerebrospinal fluid albumin cytologic dissociation. Electromyography studies and sural nerve pathology were consistent with acute sensory axonopathy. Treatment including intravenous immunoglobulin and steroid therapy was provided. Her symptoms recovered slowly without relapse, so did tibial H-reflex amplitudes.

BACKGROUND:Core decompression may provide insufficient support for the subchondral bone in the treatment of early avascular necrosis of the femoral head and increase the risk of fracture and colapse. Quadratus femoris implantation cannot only provide good biological support, but also promote the revascularization at necrotic regions, thus repairing the necrosis of femoral head. OBJECTIVE: To compare the clinical effects of core decompression with bone paste implantation and core decompression with quadratus femoris implantation on early and middle-stage avascular necrosis of the femoral head. METHODS:Eighty-three patients with early avascular necrosis of the femoral head (92 hips) admitted at the Department of Orthopedics, the First Affiliated Hospital of Zhengzhou University, China, from January 2009 to January 2012 were enroled and divided into groups of core decompression with bone paste implantation (46 cases, 49 hips) and core decompression with quadratus femoris implantation (37 cases, 43 hips) that were respectively injected with bone meal and autogenous bone and osteoinductive materials. RESULTS AND CONCLUSION: Al involved patients were folowed up. After 1 year of treatment, Harris scores in the two groups were both increased (P < 0.05). But the Harris score of core decompression with bone paste implantation group was lower than that of core decompression with quadratus femoris implantation group (P < 0.05). After 3 years of treatment, X-ray scores in the core decompression with quadratus femoris implantation group were significantly higher than those in the core decompression with bone paste implantation group (P < 0.05). These findings indicate that compared with core decompression with bone paste implantation, core decompression with quadratus femoris implantation is better to prevent femoral head colapse, improve hip function and delay the process of osteonecrosis of the femoral head.

Objective:To prepare poly-L-lactic acid(PLLA)electrospun nanofibers carrying icariin(ICA)(ICA /PLLA)and to evaluate the effects of the ICA /PLLA on MC3T3-E1 cells.Methods:ICA solution was dispersed into PLLA solution,and electrospun fibers were fabricated by W/O emulsion method.The morphology of ICA /PLLA was observed by SEM.The in vitro release kinetics of ICA /PLLA was examined.The attachment of MC3T3-E1 cells on ICA /PLLA was examined by propidiumiodide(PI)labling and ob-served under fluorescent microscope.The proliferation of the cells was measured by MTT assay.The differentiation of the cells was ob-served by alkaline phosphatase (ALP)assay.Results:In vitro,ICA was effectively released from ICA /PLLA for 22 days,cells were attached well on the surface in all groups,ICA did not affect the proliferation of MC3T3-E1 cells(P >0.05),but increased the ALP activity(P <0.05)of the cells.Conclusion:ICA /PLLA can effectively control the release of ICA and promote the differentiation of MC3T3-E1 cells.

Peliosis hepatis is a rare benign hepatic vascular disease.There is the lack of specific clinical features and preoperative diagnosis.A patient with intermittent liver area pain was admitted to the Third Central Hospital of Tianjin in April 2014.The patient with space-occupying lessions of the right lobe of liver was preliminarily diagnosed as with hepatocellular tumor or vasogenic tumor by computed tomography and B ultrasound examinations and then received liver resection combined with cholecystectomy.The result of postoperative pathological examination confirmed peliosis hepatis with adenomatous hyperplasia of liver cells.The patient was followed up till October 20,2014 without recurrence.

Objective: Small-cell esophageal cancer (SCEC) is a rare malignant tumor. Radiotherapy and chemotherapy have been considered as standard treatments for limited-stage SCEC (LS-SCEC). This study aimed to analyze the comprehensive treatment and prognosis of extensive-stage SCEC (ES-SCEC). Methods: We retrospectively analyzed the clinical data of 35 Patients with ES-SCEC from the Cancer Hospital of Tianjin Medical University between January 1989 and April 2012. Results:A total of 33 patients (94.3%) participated in follow-up visits. The overall survival of the patients ranged between 0.6 and 42.4 months with a median of 9.5 months. All of the patients suffered from extensive metastasis. Among these patients, 33 manifested metastasis at diagnosis and 2 showed metastasis after surgery. One-and two-year survival rates were 27.2%(9/33) and 9.0%(3/33), respectively. Univariate and mul-tivariate analysis results revealed that the number of chemotherapy cycles (≥4) is a risk factor of OS (P=0.02) and the only indepen-dent risk factor (P=0.049). Conclusions:ES-SCEC is a malignant tumor with poor prognosis. Radiotherapy could not improve patient survival. Chemotherapy combined other therapeutic procedures could be considered as an effective treatment.

Objective To investigate the pharmacokinetics ( PK ) and pharmacodynamics ( PD ) processes of rabeprazole in inhibiting gastric acid secretion with the combined PK-PD model. Methods A total of 10 healthy volunteers were given a intravenous infusion of 20 mg rabeprazole over a 30-min period. The concentration of rabeprazole in the plasma at different time points was detected by HPLC,and the PK parameters were calculated by DAS 2. 0 software. At the same time the intragastric pH was monitored over 24 hours to fit the PD parameters with indirect inhibition model. Results The main PK parameters,t1/2,Cmax,and AUC were(60. 5±17. 3)min,(1 299. 1±201. 0)ng·mL-1,and(106. 4±26. 0)mg·min·L-1, respectively.The corresponding PD parameters,Kin,Ke,IC50 and Imax were(8.200±3.362)h-1,(1.080±0.378)h-1,(0.286± 0. 129)mg·L-1 and(6. 93± 2. 15)pH,respectively. Conclusion The PK of rabeprazole in healthy volunteers conforms to one compartment model,and the PD fits the indirect response inhibition model. The equation can effectively establish the relationship between the blood drug concentration and the effect.

Objective To compare volume-controlled ventilation (VCV) versus pressure-controlled ventilation (PCV) improved by PEEP during one-lung ventilation (OLV).Methods Fifty ASA physical status Ⅰ-Ⅲ patients,aged 25-64 yr,weighing 40-80 kg,undergoing elective thoracotomy,were randomly divided into 2 groups (n =25 each) using a random number table:VCV + PEEP group (group Ⅴ) and PCV + PEEP group (group P).Those in group Ⅴ underwent OLV initially with VCV for 20 min followed by 4cm H2O PEEP for 20 min and then PEEP was removed.Those in group P underwent OLV initially with PCV for 20 min followed by 4cm H2O PEEP for 20 min and then PEEP was removed.At the beginning of two-lung ventilation before chest opening (T1),at 20 min of OLV before PEEP (T2),and at 20 min of ventilation with PEEP (T3),arterial blood samples were collected for blood gas analysis and the peak airway pressure (Ppeak) and development of SpO2 ＜ 95 ％ from beginning of OLV to T3 were recorded.Results Compared with group P,Ppeak at T2,3 and PaO2 at T3 were significantly increased in group Ⅴ (P ＜ 0.05).Compared with the baseline value at T1,PaO2 was significantly decreased and Ppeak was increased at T2.3 in Ⅴ and P groups (P ＜ 0.05).The incidence of SpO2 ＜ 95％ was significantly decreased and PaO2 was increased at T3 than at T2 in Ⅴ and P groups (P ＜ 0.05).Conclusion 4 cm H2O PEEP can improve VCV and PCV during OLV and the improved efficacy is better for VCV in patients undergoing thoracotomy.
