Objective To investigate the influence of c-myc on the growth, proliferation, apoptosis,invasion and cell cycle of the gastric line HFE145. Methods The cDNA of c-myc was subcloned into a constitutive vector pcDNA3.1 followed by transfection in HFE145 by using liposome. Then stable expression clones (HFE-myc) were selected. The apoptosis and cell cycles were detected using flow cytometry. The growth and proliferation were analyzed by making cell growth curves and colony formation assay respectively. The ability of invasion were tested using cell migration assay. Results HFE-myc group grew faster than HFE145and HFE-pc. The cell counts of HFE-myc in five of seven days were more than those of others significantly (P＜0.05). There was no difference between the two control group. Cell cycle analysis showed that HFE-myc group proliferated faster, mean proportion of cells in G2-M was about 25 % and higher significantly (P ＜0.05)than those of the two control groups. Results of colony formation assay showed that the mean colony formation rate of HFE-myc was 0.27 and higher than those of the control groups(P ＜0.05). The results of cell migration assay suggested that the cell migration rate of HFE-myc was not higher significantly than those of the control groups (P ＞0.05). Conclusion c-myc can promote the growth, proliferation. It can increase the proportion of cells in division stage, so promote the division. But it have little influence on the invasion of cells.

ObjectiveThe mechanism that affects the infiltration of immune cells in pancreatic cancer has not yet been clarified. This study aims to investigate the lncRNA mRNA regulatory pathways that affect immune infiltration in pancreatic cancer.MethodsTCGA and GEO gene expression data were used to screen common differential lncRNAs. We perform survival analysis, target gene prediction, GO, KEGG enrichment analysis, immune infiltration analysis, gene set enrichment analysis (GSEA) on the selected differential lncRNAs to identify the relevant pathways of immune infiltration.ResultsThe pancreatic cancer patients with high expression of ADAMTS9 AS1 have a higher survival rate when compared to patients with low expression (P=0.010). The combined analysis of TCGA and GSE86436 revealed the difference and survival-related ADAMTS9 AS1. The functional prediction of ADAMTS9 AS1 was related to immunity. Using the TIMER database, the lncRNA affected the infiltration of immune cells in pancreatic cancer tissues. The clinical analysis was demonstrated that the ADAMTS9 AS1 was related to pathological grade. The target gene SEMA3G was screened by co-expression analysis using the IMMPORT database and TIMER database. Lastly, GSEA analysis of ADAMTS9-AS1 showed that the lncRNA was also related to tumor metabolism.ConclusionThese results indicate that ADAMTS9-AS1-SEMA3G is associated with the prognosis and immune invasion level of pancreatic cancer, which can provide a theoretical basis for subsequent genetic verification experiments and immune research.

BACKGROUNDAscorbic acid has important antioxidant properties, and may play a role in the protective effects of ischemic preconditioning on later ischemia-reperfusion. Herein, we examined the role of endogenous extracellular ascorbic acid in ischemic preconditioning in the kidney.

METHODSWe developed a solitary rabbit kidney model where animals received ischemia-reperfusion only (ischemia-reperfusion group, n = 15) or ischemic preconditioning followed by ischemia-reperfusion (ischemic preconditioning group, n = 15). Ischemia-reperfusion was induced by occluding and loosening of the renal pedicle. The process of ischemic preconditioning included 15-minute brief ischemia and 10-minute reperfusion. In vivo microdialysis coupled with online electrochemical detection was used to determine levels of endogenous extracellular ascorbic acid in both groups. The extent of tissue damage was determined in kidney sections stained with hematoxylin and eosin. Serum creatinine and urea nitrogen were also detected to assess renal function.

RESULTSDuring ischemia-reperfusion, the extracellular ascorbic acid concentration during ischemia increased rapidly to the peak level ((130.01 +/- 9.98)%), and then decreased slowly to near basal levels. Similar changes were observed during reperfusion (peak level, (126.78 +/- 18.24)%). In the ischemic preconditioning group there was a similar pattern of extracellular ascorbic acid concentration during ischemic preconditioning. However, the ascorbic acid level was significantly lower during the ischemia and early reperfusion stage compared to the ischemia-reperfusion group. Additionally, the extent of glomerular ischemic collapse, tubular dilation, tubular denudation, and loss of brush border were markedly attenuated in the ischemic preconditioning group. Levels of serum creatinine and urea nitrogen were also decreased significantly in the ischemic preconditioning group.

CONCLUSIONSIschemic preconditioning may protect renal tissue against ischemia-reperfusion injury via use of extracellular ascorbic acid. In vivo microdialysis coupled with online electrochemical detection is effective for continuous monitoring extracellular ascorbic acid in the renal cortex.

OBJECTIVETo observe clinical therapeutic effects of electroacupuncture, radiation of infrared rays plus passive exercise on movement disorders of shoulder joint after operation of fracture of surgical neck of humerous.

METHODSSixty cases were randomly divided into an acupuncture plus exercise group (n = 32) and an exercise therapy group (n = 28). The acupuncture plus exercise group were treated with electroacupuncture and infrared ray radiation at rigid soft tissue on the affected side, with adjuvant points, Xuehai (SP 10), Sanyinjiao (SP 6) and Yang-lingquan (GB 34) selected for acupuncture treatment and after the needles were withdrawn passive exercise of the shoulder joints were made. The exercise therapy group were treated by active exercise after passive exercise of shoulder joint. Therapeutic effects were observed after treatment for one month, and shoulder pain scores VAS and scores of activity of shoulder joint before and after treatment were observed.

RESULTSThe total effective rate of 84.4% in the acupuncture plus exercise group was better than 64.3% in the exercise group. Before and after treatment, the VAS scores were 5.8 +/- 0.5 and 3.1 +/- 0.3 in the acupuncture plus exercise group, and 5.7 +/- 0.5, 4.3 +/- 0.4 in the exercise therapy group, respectively, with significant decreases after treatment in the two groups (both P < 0.001), the acupuncture plus exercise group being more significantly decreased than the exercise therapy group (P < 0.001). Before and after treatment, the total scores of activity of shoulder joint were 103.38 +/- 11.10 and 193.61 +/- 10.21 in the acupuncture plus exercise group, and 103.01 +/- 10.01 and 133.45 +/- 9.81 in the exercise therapy group, respectively, with significant increases after treatment in the two groups (both P < 0. 01), the acupuncture plus exercise group being better than the exercise therapy group (P < 0.001).

CONCLUSIONElectroacupuncture, radiation of infrared rays plus passive exercise has obvious therapeutic effect on movement disorders of shoulder joint after operation of fracture of surgical neck of humerous.

OBJECTIVETo compare the clinical effect on motor impairment after elbow operation between electroacupuncture combined with rehabilitation and rehabilitation training.

METHODSFifty-three cases were randomized into an electroacupuncture combined with rehabilitation group (group A, 30 cases) and a rehabilitation group (group B, 23 cases). In group A, electroacupuncture was applied on the stiff region of the elbow and Sanjian (LI 3), Shousanli (LI 10), Hegu (LI 4), Yanglingquan (GB 34), Yinlingquan (SP 9) as adjunctive acupoints. Additionally, the passive movement was followed in the elbow joint after needles removed. In group B, the constant passive movement exercise was applied. The therapeutic effect was observed after 1.5 months of treatment. Mayo Elbow Performance Score (Mayo) and range of motion (ROM) were analyzed statistically after treatment in two groups.

RESULTSMayo score and elbow ROM were all improved significantly after treatment in two groups (all P < 0.01). Compared with group B after treatment, the total Mayo score, joint motion range and ability as well as elbow ROM were all improved much apparently in group A (all P < 0.01).

CONCLUSIONCompared with rehabilitation therapy, electroacupuncture in combination of rehabilitation training can achieve much significant effect on the motion function recovery of elbow joint after fracture operation.

Chemokines, a family of small cytokines, were initially characterized as proinflammatory chemoattractant cytokines that regulated cell trafficking and adhesion. Today, attention focuses on chemokines because evidence shows that they play a critical role in tumor initiation, promotion, and progression. CXCR7, a seven-transmembrane G-protein-coupled CXC chemokine receptor, has recently been identified as binding with high affinity to chemokines CXCL11 (I-TAC) and CXCL12 (SDF-1). In this review, we highlight the current knowledge about the role of CXCR7 in the biologic processes of cancer, including cancer growth, survival, adhesion, invasion, metastasis, angiogenesis, and progression. The use of peptides, small molecules, antibodies, or small interfering RNA to target CXCR7 shows promise as new potential avenues for the treatment of cancer.

Objective To evaluate the clinical value of low kVp with iterative reconstruction in multislice spiral computed tomography of lumber vertebrae in young soldiers. Methods Sixty young soldiers who suffered from lumbar diseases were randomly divided into a control group(120 kVp)and a test group(100 kVp),who underwent CT examination with 120 kVp tube voltage in the control group and 100 kVp tube voltage in the test group.The control group went through filtered back projection (FBP)for image reconstruction.The test group applied FBP or sinogram-affirmed iterative reconstruction(SAFIRE)based on image reconstruction requirements,and then were divided into FBP test group and SAFIRE test group.The noise and SNR (signal to noise ratio)of the images were measured in each group.Meanwhile two experienced radiologists evaluated the quality of images.CTDIvol,DLP and ED were used to measure the scan dose in each group.Mean tube current was recorded by CARE Dose 4D.The data were analyzed with SPSS.Results There were no significant difference between the objective and subjective image evaluations in SAFIRE test group and the control group (P>0.05),while there were statistical differences between FBP test group and the control group or between the two test groups(P<0.05).The radiation doses in the test groups were both lower significantly than that in the control group,and the ED values in the test groups were decreased by 43% when compared with the control group. The test groups had the tube voltages not obviously different from that in the control group (P>0.05). Conclusion The radiation dose in the lumbar multislice spiral CT examination of young soldiers is decreased significantly when the tube voltage falls to 100 kVp,the same image quality as that by conventional 120 kVp tube voltage can be obtained by combining iterative reconstruction.

Objective To report our experience with retroperitoneoscopic nephroureterectomy with excision of a bladder-cuff for renal pelvic and ureteral tumors.Methods Thirty-five patients (21 women and 14 men;mean age,67 years;age range,49 -82 years) with upper urinary tract tumors underwent retro- peritoneal laparoscopic nephrourcterectomy with excision of a bladder-cuff.Of the 35 cases,15 had pelvic tumors and 20 had ureteral tumors;19 cases had the tumors on the right side and 16 on the left.Two cases had ureteral tumors combined with bladder tumors.One case had bilateral ureteral tumors then concomitantly had bladder tumors.The needle electrode was used to circleround incise the bladder thoroughly 0.5 cm away from the ureterostoma.Three trocars in the waist were used for dissecting the kidney;and the ureter was dis- sected as far distally downward.Then an incision of 5-9 cm was created in the lower abdomen to allow dis- section of the distal ureter and bladder-cuff and intact specimen extraction.Results The operation was successful in all 35 patients.The mean operative time was 3.1 h ( range,1.5-6.0h).The mean estimated blood loss was 166 ml (range,20-1600 ml).Four cases received blood transfusion.The patient's activity re- covered in 20-32 h after operation.Postoperative pathology showed transitional cell carcinoma in 30 cases, poorly differentiated adenocareinoma in 2 (ureter),squamous cell carcinoma in 1 (ureter),leiomyosarcoma in 1 (ureter),xanthogranulomatous pyelonephritis in 1.Duodenal leakage occurred in 1 patient who had had dialysis a drainage catheter was placed on the third d after operation,and the patient died of heart failure af- ter 2 months.Postoperative vesical irrigation was performed to prevent tumor recurrence.The mean hospital stay was 11 d.During a mean follow-up of 14 months(range,1-32 months),1 patient developed pelvic me- tastasis and was alive with the tumor.The other 33 patients survived free of tumor to date.No patient had re- current transitional cell carcinoma of the bladder.Conclusions Our data demonstrate that retroperitoneo- scopic nephroureterectomy for renal pelvic and ureteral tumors has shorter incision and more rapid postopera- tive recovery compared with open surgery.Using resectoscope to resect the termination of ureter allows more complete excision of the ureter.

Objective To explore the significance of the combined strategy of oncolytic virus infection,immune effector cell supplement,and immune checkpoint blocking in the treatment of gastric cancer.Methods A tumor-bearing nude mouse model of gastric cancer was treated with recombinant oncolytic vaccinia virus carrying the CXCL9 gene of T lymphocyte chemokine and IL-7gene(VV-IL7-CXCL9)obtained in previous experiments.We established a triple-intervention group of recombinant oncolytic vaccinia virus intratumoral injection+cytotoxic T lymphocyte(CTL)+immune checkpoint blocker(PD-1 monoclonal antibody),a single-intervention group of three measures,a dual-intervention group,and a blank control group.After the intervention,tumor-growth curve method,tumor-inhibition rate method,and bioluminescence method were used to detect the tumor treatment effect.ELISA was used to detect CXCL9 and IL-7 molecule concentration in the serum and tissue homogenate of animals in each group.Results The therapeutic results of animal models showed that the tumor growth in the triple-intervention group of recombinant oncolytic poxvirus+CTL+immune checkpoint blocker(PD-1 monoclonal antibody)was significantly slower than those in the other intervention and the blank control group.Conclusion The combination of recombinant oncolytic poxvirus intratumoral injection+CTL+immune checkpoint blocker(PD-1 monoclonal antibody)exert a strong antitumor effect in intervention experiments on gastric-cancer animal models.
