OBJECTIVE:To evaluate therapeutic efficacy and safety of chemotherapy combined with Xiaoaiping injection in the treatment of elderly patients with advanced gastric cancer. METHODS:60 elderly patients with advanced gastric cancer were collected from our department during 2012-2014,and then divided into union group and single group with 30 cases in each group. Single group was given irinotecan(CPT-11)150 mg/m2 added into 0.9%Sodium Chloride injection,and union group was addition-ally given Xiaoaiping injection 80 ml,qd,on the basis of single group. A treatment course lasted for 14 days,and both groups re-ceived 4 courses of treatment. The tumor markers,disease single rate,progression-free survival (PFS) and the incidence of ADR were compared between 2 groups. RESULTS:After treatment,the levels of CEA,CA199 and CA242 in 2 groups were significant-ly lower than before;the union group was significantly lower than the single group,with statistical significance(P<0.05). The dis-ease single rate of union group was 70.00%,which was significantly higher than that of single group (33.33%). PFS of union group was(11.23±2.17)months,which was significantly longer that of single group [(9.36±0.84)months],with statistical signif-icance(P<0.05). The incidence of leucopenia,alanine aminotransferase elevation,diarrhea,stomatitis and hand-foot syndrome in union group was significantly lower than in single group,with statistical significance(P<0.05). CONCLUSIONS:Xiaoaiping in-jection combined with irinotecan chemotherapy for advanced gastric cancer has obvious effect with a low incidence of ADR.

Objective To discuss the application value of the Nickel-Titanium patella concentrator(NT-PC) in surgical treatment of patellar fracture.Methods A retrospective analysis was made on clinical data of 32 cases of patellar fracture treated with the NT-PC in this hospital from January 2001 to December 2003.Results Re-examination of radiography at 12 weeks after surgery showed bone union was achieved in all the cases,with a smooth patellofemoral articular surface.The patella was preserved completely in all the comminuted fracture cases.According to the Lu's criteria,excellent and good outcomes were achieved in 26 and 6 cases,respectively,the rate of excellent or good results being 100%.The NT-PC was removed at 4 months ~ 2 years(mean,14 months) postoperatively without complications.Conclusions Application of NT-PC in the treatment of patellar fracture can preserve the comminuted patella completely,facilitate the reduction and fixation of the patellofemoral articular surface,and make early postoperative motions available.It is worthy of being recommended.

In recent years, there has been a growing emphasis on use of human adipose-derived stem cells (hADSCs) for cartilage tissue engineering owing to their ability to differentiate into chondrocytes, which is mainly induced by growth factors (GFs). In general, GFs for chondrogenic induction come from the transforming growth factor beta (TGF-beta) superfamily. To date, the most commonly used GFs for chondrogenes is TGF-beta1/3. However, the response of hADSCs to GFs may differ significantly from that of human bone marrow stem cells (hBMSCs). It has been reported that bone morphogenetic protein-6 (BMP-6) treatment induced TGF-beta receptor-I expression of hADSCs. It seems that these two cell populations varied strongly in their potency to undergo chondrogenesis in the same medium conditions. Here, we provide a concise review on various GFs used in chondrogenic differentiation of hADSCs in vitro.

Objective To investigate the effect of pegylated interferon combined thymopeptideenteric-coated tablets on CXCR3, CCR6 and serum IL-2 and soluble ligand in patients with chronic hepatitis.Methods 125 patients with chronic hepatitis B patients from June 2015 to June 2016 in our hospital were selected and divided into observation group 62 cases and control group 63 cases.The observation group was treated with pegylated interferon combined thymopeptideenteric-coated tablets, and the control group was treated with thymopeptideenteric-coated tablets, the expression of T cells in patients with CXCR3 and CCR6 was detected by flow cytometry, the serum levels of interleukin-2 and soluble interleukin-2 receptorwere measured by enzyme-linked immunosorbent assay, and compared the treatment of two groups of patients.Results After treatment, the levels of IL-2 and sIL-2R in the observation groupwere (16.4 ±5.6), (9.4 ±2.1), significantly lower than that in the control group, while CXCR3 and CCR6 were (5.8 ±0.9), (5.54 ±1.2), significantly higher than the control group, the difference was statistically significant (P<0.05), the levels of HBsAg, HBeAg and HBV-DNA in the observation group were (1.5 ±0.4), (1.6 ±0.9), (1.6 ±0.3), significantly lower than those in the control group, the difference was statistically significant (P<0.05), the levels of ALT, AST, TBIL, IBIL in the observation groupwere (34.5 ±8.7), (31.4 ±6.9), (14.6 ± 6.9), (9.4 ±2.9), significantly lower than those in the control group, the difference was statistically significant (P<0.05).Conclusion Interferon combined thymopeptideenteric-coated tablets therapy for chronic hepatitis B is helpful to improve the level of chemokine receptor and inhibit the degree of inflammatory reaction.It can help to improve liver function and inhibit viral replication in patients with hepatitis B.It is better than the treatment of chronic hepatitis with thymosin alone.

Objective: To evaluate the feasibility of performing muscle-sparing thoracotomy and intercostal sutures in the treatment of upper and/or middle thoracic esophageal cancer for the purpose of tumor control and postoperative quality of life improvement.Methods: Seven patients with esophageal cancer were treated with vertical muscle-sparing thoracotomy and Mckeown esophagectomy.Detailed clinic data were summarized and analyzed with patient follow-up information.Results: Of the 7 patients,five were still alive with a 71.4% five-year survival rate.There were no deaths resulting from the operation in this group.The mean length of thoracic incision was 11 cm.The range of hospital stays was 14 to 25 days,with a mean length of 18 days.No patients complained of impaired shoulder action,and the incision pain was hardly perceived without external stimulation 1 month after operation.Conclusion: Performing the muscle-sparing thoracotomy in the treatment of early-stage esophageal cancer located in the upper and /or middle thoracic segment yields a satisfactory long-term survival rate with an improved life quality in terms of incision pain relief and shoulder function.

Aim To explore renoprotective effect of sesamin in metabolic syndrome rats.Methods Metabolic syndrome was induced by high-fat and refined-carbohydrate diet.Sesamin(120,60 and 30 mg?kg-1?d-1)and simvastatin(5 mg?kg-1?d-1)were given to the metabolic syndrome rats at 9th week,which lasted for 16 weeks.After 24 weeks,body weight,left kidney humid weight,blood sugar,blood fat,systolic blood pressure,renal function,and indexes of oxygenation and antioxygenation for renal cortex were measured.Pathological changes,collagen deposition and iNOS protein and nitrotyrosine expression of kidney were observed by HE-staining,Masson-staining and immunohistochemical method,respectively.Results Decreasein blood sugar,blood fat,blood pressure,and MDA,?OH and NO2-/NO3-in renal cortex was obviously observed in high-and middle-dosage sesamin groups;activities of T-SOD,CAT and GSH-Px in renal cortex was increased;expression of iNOS protein and nitrotyrosine in kidney was down-regulated;inflammatory cell infiltration and collagen deposition in renal glomerulus and renal interstitium were improved;glomerular sclerosis and renal interstitial fibrosis were reversed;renal function was ameliorated.Conclusion Sesamin played a role in antioxidative stress and had protective effect upon renal diseases in metabolic syndrome rats.

Objective To study basically the toxicity of Yangling surface water. Methods Research the toxicities of the water samples through seedling cultivation experiment and the micronucleus test of Vicia faba root tip cell with original wastewater, diluted by 50% and diluted by 25%. Results The results showed that the water had mutagenesis ability, meanwhile, there was a significant dose-response relationship between the amount of micronucleus and water concentration. And the results showed that Houhe pollution is the worst,then Gaogan River and Weihui River were next, and Wei River is the last. Conclusion The surface water of the investigated area has some potential adverse effects on the health of local people and land irrigation,so more attention should paid to the control and management of contamination.
