The conventional treatment options for advanced gastric carcinoma patients remain unsatisfactory in terms of response rate and overall survival benefit. Targeted therapy plus systemic chemotherapy now becomes a new promising therapeutic option. In this review we profiled important trials of international multicenter phase Ⅲ clinical studies in patients with advanced gastric carcinoma, including ToCA trial, EXPAND trial, LOGIC trial, AVAGAST trial, REAL3 trial, and granite-1 trial. These trials warrant the role of molecular targeted therapy in patients with advanced gastric carcinoma.

BACKGROUND:Studies have shown that cancer stem cels play an important role in tumor invasion and metastasis, but studies on the role of gastric cancer stem cels in invasion and metastasis of gastric cancer cels were rarely reported.
OBJECTIVE:To study the effect of gastric cancer stem cels CSC-G on invasion and metastasis of gastric cancer cels.
METHODS: Gastric cancer stem cels CSC-G and gastric cancer cels SGC7901 were culturedin vitro for 10 days folowed by spherical colony formation assay, western blot assay for detecting OCT4, SOX2, E-cadherin and CD44 protein expression levels in gastric cancer stem cels CSC-G and gastric cancer cels SGC7901, and Transwel assay for detecting the invasion and migration of gastric cancer stem cels and gastric cancer cels SGC7901.
RESULTS AND CONCLUSION:Gastric cancer cels SGC7901 in RPMI1640 medium presented with adherent growth and were quadrilateral or polygonal after passage; gastric cancer stem cels CSC-G in serum-free medium presented with suspension growth, and adherent gastric cancer stem cels were spindle-shaped or round. Compared with gastric cancer cels SGC7901, the protein expressions of OCT4, SOX2 and CD44, the number of cancer cel spheres and the number of trans-membrane cels were significantly increased in the gastric cancer stem cels CSC-G (P < 0.05), and the expression of E-cadherin protein was significantly decreased (P < 0.05). These findings indicate that the gastric cancer stem cels CSC-G can be successfuly cultured in vitro, and have enhanced invasion and migration compared with the gastric cancer cels SGC7901, which play an important role in gastric cancer invasion and metastasis.

Objective To investigate the effect of Kang' ai injection and Shenqifuzheng injection on liver function of patients with advanced primary liver cancer after being performed transcatheter arterial chemomembolization (TACE).Methods 120 patients with advanced primary liver cancer were randomly divided into three groups:a control group,a Kang'ai injection group,and a Shenqifuzheng injection group,with 40 patients in each group.All three groups were treated with TACE,and after TACE the control group was treated with anti-infection,inhibiting-acid,protecting-liver function and Shuganning tablets,20 ml/day.On this basis,the Kang'ai injection group was additionally injected with Kang'ai injection,40ml/day,and Shenqifuzheng injection group was additionally injected with Shenqifuzheng injection,250ml/day.All three groups were treated for 15 days.Liver function was tested and compared at the 3rd day,the 7th day and 14th day after TACE in all three groups.Results At the 14th day after TACE,ALT,AST,TBiL,and TBA of the Kang' ai group and Senqifuzheng group [(40.35 ± 10.10) μmol/L、(37.52 ± 10.57) μmol/L、(40.13 ± 8.36) μmol/L、(45.19 ± 19.65) μmol/L in Senqifuzheng group; (40.11 ±7.31) μmol/L,(34.99±9.38) μmol/L,(32.15±6.58) μmol/L,(40.75 ± 6.79) μmol/L in Kang'ai group] were greatly improved than the control group [(61.28 ± 13.38) μmol/L,(57.53 ± 13.36) μmol/L,(68.69± 7.25) μmol/L,(67.75 ± 17.88) μmol/L],with statistical significance (P＜ 0.01).Conclusion Kang'ai injiection and Shenqifuzhcng injection both can reduce liver function damage caused by TACE,thus they can be used together with TACE for treating advanced primary liver cancer.

Objective To evaluate the effect of total parenteral nutrition (TPN) on hyperemesis gravidarum (HG) and pregnancy ending.Methods 27 cases of HG were treated with TPN and 30 cases with the routine infusion to adjust water electrolyte and acid base balance for the purpose of observation of vomiting stopping,time of turning ketonic negative and pregnancy ending.Results After 3 day treatment with TPN,stopping vomiting rate was 55.6%,time of turning ketonic negative was (3.1?0.84) days and neonatal weight was (3.4?0.38) kg,which was 13.3%,(5.2? 1.06) days and (2.9?0.45) kg respectively in control group.There was significant difference between the two groups (P

(0.05). The CsA dosage and C 2 concentrations were lower in group II than in group I.Conclusion Neoral C 2 monitoring are beneficial to clinical outcomes in elderly Chinese renal transplant recipients and C 2 (concentration) is lower in elderly recipients than in young ones.

Objective To compare the efficacy and safety of Tacrolimus(FK506)and Neoral CsA in conjunction with MMF(2.0g/d)and steroid in preventing renal allograft rejection.Methods 98 cases of renal transplant recipients were randomly divided into two groups:FK506 group(n=40),receiving tacrollimus,MMF and prednison(Pred);CsA group(n=58),receiving CsA,MMFand Pred.Results The mean follow-up time in both two groups Was 12.5 months.Acute transplanted renal rejection occurred in 2 cases in FK506 group and 9 cases in CsA group respectively.The one-year person/kidney survival rate was 100%/100%in FK506 group and 100%/94.8%in CsA group respectively.The dosage of Pred in FK506 group was lower than in CsA group.12 cases in FK506 group had stopped using Pred.Hypergly cermia occurred in 7 cases in FK-506 group.Polytricosis,gingival hyperplasia and liver function disorder dominantly occurred in CsA group.Infection Was found in 9 cases of FK506 group and 11 cases of CsA group respectively.Conclusion FK506 combined with MMF could decrease the occurrence of acute trans planted renal rejection and the dosage of Pred.The good adjustment of the dose of FK506 iS helpful for re ducing the side effects and preventing rejection.

Thyroid carcinoma is the most common malignancy in the endocrine system.Most patients cannot be cured with operation alone.The concept and implementation of multidisciplinary team (MDT) in clinical oncology attributes to improved diagnosis and treatment of cancer.MDT plays an important role in diagnosis,treatment,and post operational management of thyroid carcinoma,as well as in the application of novel techniques and translational medicine.MDT can maximize the expertise of various disciplines,strengthen inter disciplinary cooperation,and provide standardized and individualized comprehensive treatment for patients with thyroid cancer.The most important benefit of MDT is that individual patient gets the most appropriate treatment decision made by a team of experts,including endocrinologists,nuclear medicine specialists,pathologists,radiologists,radiation therapists,and surgeons.This will be of great significance to improve quality of life and prognosis,at the same time,avoid over-treatment of thyroid cancer.

Objective The expression of TGF-β1 and IL-10 in the grafts of inbred mice with rejection of heart transplantation were studied and the interaction of them in the rejection of heart transplantation in inbred mice investigated.Methods Allografts were divided into 2 groups:control group (n =70),cyclosporin A-treated group (CsA group,n =70).Hearts from inbred BABL/c mice were transplanted into a cervical location in the other recipients and the survival time of the allografts was observed.The local expression of TGF-β1 and IL-10 was detected at day 1,3,7,11,14,21 by reverse transcription polymerase chain reaction(RT-PCT) respectively.Results The survival time of the allografts was (20.3 ± 1.7) days in control group,and(32.2 t 3.4) days in CsA group (P ＜ 0.01).The levels of the two cytokines expression were up-regulated in CsA group.The up-regulation of TGF-β1 was closely correlated with the survival of the grafts.Conclusion The expression and production of the two cytokines is up-regulated probably cause of administ ration of cyclosporin A,and favorite to the heart graft survival,and action of these two cytokines are probably interrelated.

Objective To study basic thyroid stimulating hormone (bTSH) levels impact on outcomes of in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) in Qinghai.Methods Totally 282 cases with IVF cycles and 93 cases with ICSI cycles were studied prospectively,according to bTSH level,patients were divided into four groups.Reproduction rate,clinical pregnancy rate,miscarriage rate and live birth rate were studied among four groups.Results (1) In 375 cases with IVF/ICSI cycles,bTSH was positively correlated with abortion rate (r=0.42,P=0.04),but live birth rate and growing rate showed negative correlations with bTSH (r=-0.42,-0.28; P=0.04,0.03).bTSH and the number of eggs,the number of fertilized eggs,the number of embryos,biochemical pregnancy rate,and clinical pregnancy rate were no significant correlation (all P＞0.05).(2) Among women at group of ≤1.7,＞1.7 and ≤2.5,＞2.5 and ≤3.5,＞3.5 mU/L,the implantation rates were 28.7％,27.3％,37.7％ and 19.2％,live birth rates were 80.9％,75.0％,82.7％,and 59.8％,abortion rates were 19.0％,15.0％,16.7％,40.1％; they all showed significant difference (all P＜0.05).Abortion rate in women with high bTSH level was higher than that of women with lower bTSH level,however implantation rate,live birth rate in women with high bTSH level were lower.Conclusion When bTSH level is ＞3.5 mU/L,the abortion rate were increased,but live birth rate,rate of implantation were decreased.
