Objective:To compare the survival of resected gastric cancer patient treated with oxaliplatin, 5-fluorouracil, and leu-covorin (FOLFOX6) with those treated with oxaliplatin and capecitabine (XELOX). Methods:A total of 147 resected gastric cancer pa-tients accepted the treatment. Among them, 99 were treated with FOLFOX6 and 48 were treated with XELOX. Adverse events and sur-vival rates of the two groups were compared. Results:Incidence of leukopenia and hepatic dysfunction in the FOLFOX6 group was sig-nificantly higher than that of the XELOX group (P<0.05), whereas hand-foot syndrome in the XELOX group was significantly higher than that of the FOLFOX6 group (P=0.016). By contrast, the incidence of other adverse events, such as anemia, thrombocytopenia, nau-sea and vomiting, diarrhea, kidney dysfunction, peripheral neurovirulence, and oral mucositis, was not significantly different (P>0.05) between the two groups. After 1, 3, and 5 years, disease-free and overall survivals between the two groups were not significantly differ-ent (P>0.05). Conclusion:The effects of FOLFOX6 and XELOX adjuvant chemotherapies on long-term survival of resected gastric cancer patients were found to have no significant difference.

Objective To evaluate the preventive effect of compound matrine injection on hepatic lesion caused by chemotherapy. Methods 178 patients after gastric and colorectal cancer resection were enrolled into three groups randomly. 56 patients in group A received MFOLFOX6 regimen treatment only, 62 patients in group B received both normal treatment and combined compound matrine injection,60 patients in group C received both normal treatment and glutathione. The change of liver function were observed. Results There was no the hepatotoxicity of Ⅲ-Ⅳ degree in all groups;the incidence of bilirubin and transaminase increasing in group B and C was significantly lower than that group A(P ＜0.05), but the incidence of ALP/GGT increasing showing no significant difference among the three groups; 72.7 % of the incidence of hepatic lesion in group A happened firstly before the seventh cycle,it was 27.3 % and 33.3 % respectively in group B and group C, the time of the emerging of hepatotoxicity in group B and C was markedly delayed than that group A (P ＜0.05); there was not significant difference between group B and group C in both bilirubin and transaminase increasing and the time of the emerging of hepatotoxicity (P ＞0.05). Conclusion Compound matrine injection can prevent and postpone the happening of hepatic lesion caused by adjuvant chemotherapy after digestive tract cancer resection, The result is equal to glutathione. Compound matrine injection also has antineoplastic effects, so the clinical superiority is more obvious.

Objective:To investigate the role of Leukotactin-1(LKN-1),CC receptor 1(CCR1)and CC receptor 3(CCR3)in the pathogenesis of hypertensive disorder complicating pregnancy(HDCP),the expressions of these factors in placentas were measured.Methods:The levels of LKN-1,CCR1 and CCR3 in placentas were measured from 32 patients with HDCP(study group)and 32 normal pregnant women(control group)by western blot(WB).The localization of these factorsin placentas were detected by immunohistochemistry(IHC).Results:LKN-1 protein expression was negative in placentas from the two groups by WB and IHC,while both CCR1 and CCR3 in the HDCP group were significantly lower than those in the control group(CCR1 0.66±0.06 vs 0.88±0.03.CCR3 0.17±0.01 vs 0.27±0.01,P<0.01).CCR1 was localized in vascular endothelial cells and stroma cells in both groups,but rare in the trophoblast layer.CCR3 was localized in vascular endothelial cells and trophoblast cells in both groups.Conclusions:There is no LKN-1expression in placentas from the two groups.Down regulation of CCR1 and CCR3 may associate with the pathogenesis of HDCP.

A model of s bacute senility state was established in mice by successive retrobulbar injectiou of 80 mg/kg D-galactose for 50 days. Concomitant oral administration of 4 g/kg and 8 g/kg gastrodia can effectively recovcr the decreased ability of the passive avoid ance reaction in the model animals.The activity of RBC SOD and the contents of hydroxyproline in the animals skin were markedly increased as well as the lipofuscin of myocardium. However, gastrodia was less effective to lower lipofuscin in liver and brain.

Objective To observe the correlation between vitamin D and liver cirrhosis classification in hepatic diabetes.Methods Thirty-eight patients with hepatic diabetes,48 patients with type 2 diabetes and 30 cases of healthy controls were collected.The level of serum 25-(OH)D3 was determined,and the Child-Pugh score was calculated.The correlation between pathogenesis and pathogenetic condition of hepatic diabetes was analyzed.Results The levels of serum 25-(OH)D3 in hepatic diabetes patients,type 2 diabetes patients and healthy controls were (38.23 ± 12.47),(63.33 ± 13.58) and (86.14 ± 16.25) μ mol/L,and there was statistical difference (P ＜ 0.05).There was negative correlation in hepatic diabetes between serum 25-(OH)D3 level and liver cirrhosis Child-Pugh score (r =-0.363,P ＜ 0.05).Conclusion Low level of vitamin D may be one of the pathogenesis of hepatic diabetes.

Objective To observe the expression of thioredoxin (Trx) and thioredoxin-interacting protein (Txnip) in the kidney of type 2 diabetic rats induced by streptozotocin and the effect of probucol treatment on thioredoxin system. Methods Thirty male SD rats were divided into control group( C, n = 10), diabetes group ( D, n =10), and probucol treated diabetic group ( P, n = 10). After eight weeks of probucol treatment, the expressions of Trx and Txnip in the kidney of three groups were measured by RT-PCR, Western blot, and immunohistochemistry. Body weight,24 h microalbuminuria( ALB), fasting plasma glucose( FPG), fasting insulin( HNS), blood urea nitrogen (BUN), creatinine (Cr), malondialdehyde ( MDA ), superoxide dismutase ( SOD ), and catalase (CAT) were determined. Results Compared with group C, Trx was markedly decreased in group P (0. 162 ±0. 008 vs 0. 239 ±0. 006, P＜0.05 ), while Txnip was significantly increased (0. 159±0.003 vs 0. 091 ±0.016, P＜0.05 ). Trx in group P was increased as compared with group D (0. 162 ±0. 008 vs 0. 108 ± 0. 013, P ＜ 0. 05 ), while Txnip was lowered (0. 159±0.003 vs 0. 236±0.009 ,P＜0.05 ). FPG, 24 h ALB, BUN, Cr,and MDA levels in group D were markedly increased as compared with group C (P＜0. 05), while the activity of SOD, CAT, and FINS levels were decreased apparently (P＜0.05). The above markers except for FPG in group P were ameliorated (P＜0. 05 ).Conclusions Probucol attenuated oxidative stress by means of partially restoring Trx function and reducing Txnip expression, and thus played a major role in renoprotection of type 2 diabetic nephropathy.

Objective: To investigate the association between self-rated health status and mortality risk, and to evaluate the predictive value of self-rated health status for mortality risk among the elderly. Methods: Based on the China Health and Retirement Longitudinal Study (CHARLS) database, data of sociodemographic information, self-rated health status and mortality of the elderly aged 60 years and older were collected from 2011 to 2018. The association between self-rated health status and mortality risk among the elderly was analyzed using a multivariable Cox proportional risk regression model. Results: Totally 4 850 individuals were included, with an median age of 65 (interquartile range, 8) years. There were 2 485 males (51.24%) and 2 365 females (48.76%). There were 877 individuals (18.08%) rated their health as good, 2 078 individuals (42.85%) as general, 1 895 individuals (39.07%) as poor. A total of 28 955 person-years were followed up, with an average follow-up of 5.97 years per person. There were 855 deaths by the end of follow-up in 2018, and the median survival time was 7 (interquartile range, 3) years. Multivariable Cox proportional risk regression analysis showed that there were interactive effects of age, sex and self-rated health status on mortality, respectively (both P<0.05). The results of gender-stratified analysis showed that there was no significant association between self-rated health status and mortality risk in old women (P>0.05). The mortality risk was higher in old men with poor self-rated health than with good self-rated health (<70 years, HR=5.382, 95%CI: 3.263-8.876; 70 to 79 years, HR=3.536, 95%CI: 1.070-11.686; ≥80 years, HR=3.043, 95%CI: 1.827-5.066). Conclusion There is an association between self-rated health status and mortality risk among the elderly, the old men with poor self-rated health had a higher mortality risk.

Objective To investigate the immunomodulatory effects of heme oxygenase-1 ( HO-1) modified rat bone marrow mesenchymal stem cells ( BM-MSCs) on lymphocytes .Methods Rat BM-MSCs were cultured and identified in vitro.HO-1 gene was transduced into BM-MSCs via recombinant adenovirus (rAdV) to construct HO-1/BM MSCs, which were then co-cultured with rat spleen lymphocytes .The cellu-lar activity of lymphocytes was detected by using MTT method .The cell cycle distributions were analyzed by propidium iodide staining and flow cytometry .ELISA was used to detect the level of cytokines in the super-natant of cultured cells .The expression of lymphocyte activation markers , CD25 and CD71, were measured by using fluorescence labeled antibodies and flow cytometry .Results Compared with the control group , the lymphocytes co-cultured with HO-1/BM MSCs showed a suppressed proliferation and cell cycle progression . HO-1/BM MSCs inhibited the secretion of IL-2, TNF-αand IFN-γ, but enhanced the secretion of IL-10 in lymphocytes.Furthermore, the expression of CD25 and CD71 were also down-regulated by HO-1/BM MSCs. Conclusion Compared with BM MSCs , HO-1/BM MSCs show higher immunosuppressive effects on lym-phocytes .

Objective To study the expression of tight junction factors in human placental tissues derived from assisted reproductive technology (ART) and natural pregnancy and its role in placental barrier.Methods Ten placental samples were collected from the women who had undergone ART treatment and 11 placenta were collected from control group.Transmission electron microscope (TEM) examination was utilized to detect the morphology of placental tight junctions.The mRNA of claudin (CLDN) 1,CLDN4,CLDN5,CLDN8,zonula occudens (ZO) 1 was detected by real-time PCR and the protein of CLDN4,CLDN8 and occludin (OCLN) were measured by western blot.Results TEM microscopy results showed that placenta samples derived both ART and control placenta had normal microscopic histological features of tight junctions,localized in the apical part of the syncytium and also between the cell-cell contacts of fetal blood vessel endothelial.The expression level of CLDN4 mRNA were 0.87 ±0.17 in ART group and 1.18 ± 0.30 in control group,respectively.The expression level of CLDN8 mRNA were 3.25 ± 2.32 in ART group and 1.08±0.41 in control group,respectively.The mRNA level of CLDN4 and CLDN8 were significantly differentially expressed in ART derived placenta when compared with control groups.The expression level of CLDN1,CLDN5,OCLN and ZO1 mRNA were 0.49 ± 0.44,0.80 ± 0.20,0.92 ± 0.18 in ART group and 1.09±0.82,1.21 ±0.78,0.80± 0.27 in control group,respectively,in which there were no significant differences between two groups.Western Blot analysis showed the protein levels of tight junctions CLDN4,CLDN8 and OCLN did not differ between groups.Conclusions Tight junction factors were expressed in human placental tissues.Tight junction derived from ATR platenta might have mild dysfunction.
