Objective To investigate the expressions of TK1 (thymidine kinase 1) in PHC (primary hepatic carcinoma). Methods TK1 and AFP in serum of 33 cases of PHC (primary hepatic carcinoma), 38 cases of hepatic cirrhosis,36 cases of hepatitis and 35 cases of healthy people were detected by means of Western blot—enhanced chemiluminecence and electrochemiluminescence. Results The difference of TK1 level in PHC group indicated significance when compared with that in hepatic cirrhosis group , hepatitis group and control group (U value was 436.4, 352.1, 163.6, respectively, all P < 0.01). TK1 level in patients with PHC was related with differentiation (χ2 = 7.476,P < 0.05) and TNM stage (χ2 = 7.227,P < 0.05),but not with sex, age, tumor diameter, number of tumors, vascular invasion, lymph node metastasis (P > 0.05). Kaplan-Meier curve analysis revealed that PHC patients with TK1≤ 2.0 pmol/L had a significantly shortened overall survival when compared with those with TK1 > 2.0 pmol/L (χ2 = 3.954,P < 0.05). Multivariable Cox regression analysis indicated that the level of TK1 and TNM stage were the independent risk factors for patients with PHC (all P <0.05). Conclusions The detection of TK1 has a certain clinical value in the diagnosis, monitoring and evaluation of the prognosis of the PHC.

OBJECTIVETo explore the clinical application of laparoscopy in gastrointestinal abdominal emergency operation for patients over 65 years old.

METHODSClinical data of 138 cases (age>65 years) with acute abdomen undergoing laparoscopic surgery from January 2006 to June 2014 were analyzed retrospectively. Data of 170 cases treated by laparotomy during the same period were enrolled as controls.

RESULTSThe laparoscopy group and the laparotomy group showed statistically significant differences in blood loss [(107.1±47.7) ml vs. (163.6±106.5) ml, P=0.000], postoperative complications rate [2.9%(4/138) vs. 12.9%(22/170), P=0.022], hospital stay [(10.5±7.5) d vs. (16.5±9.9) d, P=0.044], postoperative ambulation time [(25.6±7.7) h vs. (33.2±5.6) h, P=0.020], and recovery time of postoperative gastrointestinal function [(36.9±9.1) h vs. (49.3±10.6) h, P=0.031]. Patients with acute appendicitis, upper digestive tract perforation and bowel obstruction in the laparoscopy group were superior to those in the laparotomy group in hospital stay, postoperative ambulation time, recovery time of postoperative gastrointestinal function and intraoperative blood loss(all P<0.01), while no significant differences in colon perforation and mesentery diseases were found in hospital stay, intraoperative blood loss and recovery time of postoperative gastrointestinal function between the two groups (all P>0.05).

CONCLUSIONSCompared with laparotomy, the laparoscopy offers the advantages of less trauma, faster recovery, shorter hospital stay, and lower postoperative complications rate for patients over 65 years with acute abdomen.

Objective To study the clinical efficacy of Bikini incision minimally invasive total hip arthroplasty on elder patients with femoral head necrosis and its effect on bleeding.Methods Seventy-six elder patients with femoral head necrosis in Sanmenxia Central Hospital from January 2015 to December 2016 were randomly divided into the study group(38 cases)and the control group(38 cases).The patients in the study group were treated with Bikini incision minimally invasive total hip arthroplasty by anterior approach,while the control group underwent total hip arthroplasty by anterolateral approach.Harris score and WOMAC score were used to evaluate the clinical function of hip joint.The operation time,length of incision,intraoperative blood loss, blood transfusion,hospitalization time,hemoglobin level at 72 h after surgery,the first ambulation time,the lower limb length discrepancy,postoperative complication were recorded and compared between two groups.Results The Harris scores at 1,2,4 months after operation in the two groups were significantly improved(P<0.05), while WOMAC scores of patients at 1,2,4 months after operation were significantly lower than those before treatment(P<0.05).However,there were no significant differences at different time between the groups(P>0.05).The hospitalization time and the first ambulation time in the study group were significantly shorter than those in the control group((6.1±2.8)d vs.(7.9±3.2)d,P=0.011;(5.3±1.5)d vs.(6.4±1.7)d,P=0.004).After 4 months of treatment,the lower limb length discrepancy in the study group was less than that of the control group((6.5 ± 2.3)mm vs.(10.4 ± 3.5)mm,P<0.01).In addition,there were no significant differences between two groups in the operation time,length of incision,complication occurrence,intraoperative blood loss and blood transfusion(P>0.05).Conclusion Treating femoral head necrosis with Bikini incision minimally invasive total hip arthroplasty can achieve favorable effectiveness,with no increase in intraoperative blood loss and rapid recovery of postoperative joint function,but further follow-up is needed.

PURPOSE: Periostin mediates critical steps in gastric cancer and is involved in various signaling pathways. However, the roles of periostin in promoting gastric cancer metastasis are not clear. The aim of this study was to investigate the relevance between periostin expression and gastric cancer progression and the role of stress-related hormones in the regulation of cancer development and progression. MATERIALS AND METHODS: Normal, cancerous and metastatic gastric tissues were collected from patients diagnosed with advanced gastric cancer. The in vivo expression of periostin was evaluated by in situ hybridization and immunofluorescent staining. Meanwhile, human gastric adenocarcinoma cell lines MKN-45 and BGC-803 were used to detect the in vitro expression of periostin by using quantitative real-time polymerase chain reaction (PCR) and western blotting. RESULTS: Periostin is expressed in the stroma of the primary gastric tumors and metastases, but not in normal gastric tissue. In addition, we observed that periostin is located mainly in pericryptal fibroblasts, but not in the tumor cells, and strongly correlated to the expression of α-smooth muscle actin (SMA). Furthermore, the distribution patterns of periostin were broader as the clinical staging of tumors progressed. We also identified a role of stress-related signaling in promoting cancer development and progression, and found that isoprenaline upregulated expression levels of periostin in gastric cancer cells. CONCLUSION: These findings suggest that the distribution pattern of periostin was broader as the clinical staging of the tumor progressed and found that isoprenaline upregulated expression levels of periostin in gastric cancer cells.
