OBJECTIVE:To investigate the effect of shen-fu injection on toxic reaction relief in the chemotherapy for moderate to advanced non-small cell lung cancer(NSCLC).METHODS:130 patients of NSCLC were randomly divided into treatment group and control group,2 groups both received the second-generation regimen for chemotherapy,the major chemotherapeutic agents included vinorelbine,gemcitabine and paclitaxel,the treatment group was given intravenous shen-fu injection 60ml/d for continuous2weeks plus chemotherapy.RESULTS:The toxic reactions in treatment group significantly decreased compared to that in the control group(P

BACKGROUND:Recently, the effects of human umbilical cord mesenchymal stem cel s (hUCMSCs) and placenta-derived mesenchymal stem cel s (PDMSCs) on treatment of acute graft versus host disease (aGVHD) have been confirmed in some in vitro studies or animal models. But there are stil no reports comparing the therapeutic effects of these two cel types. OBJECTIVE:To compare the immunosuppressive function of hUCMSCs and PDMSCs in vitro or in a mouse aGVHD model. METHODS:(1) In vitro experiment. Human peripheral blood mononuclear cel s (PBMCs) were isolated and divided into four groups:PBMCs cultured alone, PBMCs stimulated with phytohaemagglutinin (PHA), PHA stimulated-PBMCs cocultured with hUCMSCs, PHA stimulated-PBMCs cocultured with PDMSCs. After 5 days, PBMCs proliferation and interferon-γlevel in cel supernatant were measured. (2) In vivo experiment. Fifty-seven BABL/C(H-2d) mice exposed to 8.5 Gy irradiation were randomly divided into five groups:only saline injection group, syngeneic bone marrow transplantation group, al ogeneic bone marrow transplantation group, aGVHD group, hUCMSCs treatment group, PDMSCs treatment group. The clinical aGVHD score, histopathology of skin, liver, and smal intestine, and survival time were analyzed at days 11, 14, 21 after transplantation. RESULTS AND CONCLUSION:(1) In vitro test:compared with the hUCMSCs, PDMSCs had stronger anti-inflammatory function. (2) In vivo test:The clinical scores on acute graft versus host disease were significantly lower in the hUCMSCs and PDMSCs treatment groups than that in the aGVHD group (P<0.05). The survival rates of mice were significantly increased in the hUCMSCs and PDMSCs treatment groups compared to the aGVHD group (P<0.05). Evident skin lesions were not found in al groups. Although smal intestine mucosal lesions were found in al groups, the damage level seemed similar. Notably, significant difference was found in the liver that multifocal necrosis and a large number of inflammatory cel s were seen in the aGVHD group, but less necrosis and inflammatory cel s in the hUCMSC and PDMSC treatment groups. In conclusion, hUCMSC and PDMSC are comparably effective in the treatment of aGVHD in mice.

Objective To study the prevalence situation of chronic diseases among teachers from some middle and primary schools in Chongqing City.Methods The physical examination data of 6969 teachers in 52 middle and primary schools in a district of Chongqing major city were collected.The survey data of overweight,obesity,hyperlipidemia,osteoporosis,fatty liver and hyperuricemia were statistically analyzed.Results The total morbidity rates of overweight,obesity,hyperlipidemia,osteoporosis,fatty liver and hyperuricemia were 31.3 ％,7.5 ％,35.1％,34.7 ％,22.4 ％ and 22.2 ％ respectively.The incidence rates of above diseases had difference among the age periods of ≤44 year old,＞44 ＜60 years old and ≥60 year old (P＜0.05).The incidence rate was significantly increased with age increase (P＜0.05).The incidence rate of osteoporosis in females was higher than that in males(P＜ 0.01);while the incidence rate of fatty liver and hyperuricemia in males were higher that in females (P＜0.01).Conclusion The incidence of chronic diseases among teachers in middle and primary schools is worth attention.Therefore it is necessary to carry out the health education aiming at the teacher population characteristics,strengthen their heath management and behavior intervention for increasing their health level.

Osteosarcoma is a clinically common primary malignant bone tumor.Its treatment is still not ideal because of the high de-gree of malignancy and early metastasis.Understanding the molecular mechanism and the biological characteristics of malignant os-teosarcoma,and exploring the effective treatment have become the focus of osteosarcoma research at home and abroad.A long non-coding RNA,lncRNA,is involved in the regulation of a variety of cellular functions and plays an important role in the development of osteosarcoma.Recently,lncRNA has been increasingly reported in osteosarcoma research.It has been found to affect the proliferation, invasion,and migration of osteosarcoma cells by interacting with proteins,mRNAs,and miRNAs.This article reviews the research on ln-cRNA based on recent reports regarding its role in the molecular mechanism of osteosarcoma.
