Ginsenosides, belonging to a group of saponins with triterpenoid dammarane skeleton, show a variety of pharmacological effects. Among them, some ginsenoside derivatives, which can be produced by acidic and alkaline hydrolysis, biotransformation and steamed process from the major ginsenosides in ginseng plant, perform stronger activities than the major primeval ginsenosides on inhibiting growth or metastasis of tumor, inducing apoptosis and differentiation of tumor and reversing multidrug resistance of tumor. Therefore ginsenoside derivatives are promising as antitumor active compounds and drugs. In this review, the derivatization methods, ginsenoside derivatives and their anti-tumor structure-activity relationship have been summarized for providing useful information for the research and development of novel antitumor drugs.

Objective To evaluate the effects of low dose Ethyl Carbamate (EC)on the immune function of ICR mice and to provide evidences for developing food safety standard.Methods The ICR mice were divided into four groups,and three groups were treated with 0.1 7,0.83,1 .67 mg/kg·bw EC respectively and the control group was treated with distilled water only.The immune function of ICR mice was determined by five aspects,including cellular immunity,humoral immunity,mononuclear macrophages's phagocytosis,natural killer cell activity and the organ coefficients of immune organs. Results Compared with the control group,the 1 .67 mg/kg·bw EC significantly inhibited the proliferation of spleen lymphocyte,natural killer cell activity and the hemolysis plaque -forming ability induced by ConA (P <0.05 ). Conclusion EC can cause the inhibition of normal mouse's immune function.

Primary mediastinal choriocarcinoma in male is not a very common disease,with nonspecific clinical manifestations.Gynecomastia and testicular atrophy are present in some cases.The levels of serum human chorionic gonadotropin are often significantly increased.Giant lump in the mediastinum and bilateral lungs multiple metastases can be seen on the computed tomography for lung.The diagnosis for it depends on pathological biopsy.Current treatment method is a comprehensive,consisting of chemotherapy,radiotherapy and surgery.This paper reported a case of primary mediastinal choriocarcinoma in male,who were diagnosed and treated in the Second Xiangya Hospital of Central South University.He was admitted for cough and hemoptysis,and finally diagnosed by biopsy.The prognosis is very poor.Therefore,it is important to take physical examination regularly because it can be detected and diagnosed early.

Objective To investigate the effects of long non-coding RNA FEZ family zinc finger 1 antisense RNA 1(lncRNA FEZF1-AS1)on enhancer of zeste homolog 2(EZH2)in regulation of proliferation,migration,invasion and epithelial-mesenchymal transition(EMT)of pulmonary interstitial cells and its mechanism.Methods The A549 cells human lung adenocarcinoma cell line were divided into control group and model group[model cells were induced into lung interstitial cells after being treated with transforming growth factor β1(TGF-β1)20 ng/mL for 48 h].The protein expression of E-cadherin,N-cadherin and vimentin in each group was detected by Western blot.The expression of lncRNA FEZF1-AS1 and EZH2 in the two groups was detected by RT-qPCR.Cells in the trans-fection group were divided into si NC group,lncRNA FEZF1-AS1+OE vector group and si lncRNA FEZF1-AS1+OE EZH2 group.Cell proliferation was examined by CCK-8 method,cell migration was detected by cell scratch,and cell invasion was detected by Transwell assays.The protein expression of E-cadherin,N-cadherin,vimentin and EZH2 in each group was detected by Western blot.The direct binding effect of FEZF1-AS1 and EZH2 was deter-mined by RNA immuno-precipitation(RIP).Results Compared with the control group,the protein expression level of E-cadherin in the model group was significantly decreased(P＜0.05),and the protein expression of N-cadherin and vimentin was significantly increased(P＜0.05).Compared with the control group,the expression level of lncRNA FEZF1-AS1 and EZH2 genes was significantly increased in the model group(P＜0.05).Compared with si NC group,the proliferation,migration and invasion ability of si lncRNA FEZF1-AS1+OE vector group were decreased,the ex-pression of E-cadherin protein was increased while the expression of N-cadherin,vimentin and EZH2 was decreased(P＜0.05).Compared with si lncRNA FEZF1-AS1+OE vector group,the proliferation,invasion and migration of si lncRNA FEZF1-AS1+OE EZH2 group were increased(P＜0.05).E-cadherin expression was decreased,while N-cad-herin,vimentin and EZH2 expressions were increased(P＜0.05).RIP experiment further confirmed that lncRNA FEZF1-AS1 had direct binding effect with EZH2.Conclusions LncRNA FEZF1-AS1 can promote the proliferation,invasion,metastasis and EMT process of pulmonary fibrosis cells by regulating EZH2.

OBJECTIVETo analyze the global gene expression profile of primary cultured nasopharyngeal carcinoma (NPC) cells using cDNA microarray techniques to screen new candidate genes related to the occurrence and progression of NPC.

METHODSA NPC cell line C666 and primary cultured NPC cells from biopsy specimens in 5 cases were analyzed with microarray techniques in comparison with 3 normal nasopharyngeal epithelial (NPE) biopsy specimens. Several differentially expressed genes identified from the microarray results were verified by fluorescence real-time PCR (FQ-PCR) and immunohistochemistry (IHC).

RESULTSPrimary cultured cells of both NPC and NPE were verified by cytokeratin IHC, EBER1 in situ hybridization and EBV-DNA real-time PCR. Compared with NPE cells, a total of 493 genes in at least 4/6 of the samples were identified to be differentially expressed in the primary cultured NPC cells, including 264 up-regulated and 229 down-regulated ones. Several differentially expressed genes according to the microarray results were confirmed by real-time PCR and IHC.

CONCLUSIONcDNA microarray technique provides an effective and accurate means for global gene expression profiling of primary cultured NPC cells to screen the differentially expressed genes, which may serve as an important basis for studying the mechanism, classification and diagnosis of NPC at the molecular level.

OBJECTIVETo uncover the transmission patterns of the HIV epidemic in Dehong prefecture.

METHODSThe reviewed case reports, data of sentinel surveillance, testing and special survey were analyzed by SAS 8.0 program. The transmission patterns were modeled by utilizing data including sizes of the whole population and the high risk groups, high risk behavior data from 1989 to 2007, and the population index such as sex ratio and fertility rate.

RESULTSIn 2005, case reports showed the proportion of people infected with HIV through sexual contact was 39.1%, and 46.9% in 2006. Among 1636 cases reported between January 1 to September 20, 2007, the proportion of people infected with HIV through sexual contact was 52%. From 1989 to 2007, the proportion of HIV infection among drug users was declining, while HIV infection through sexual contact was rising after standardizing the population tested/surveyed. The Asian Epidemic Model has shown that the proportions of incident HIV infections through sexual transmissions were 50.6%, 52.3% and 52.7% respectively from 2005 to 2007. Correspondingly, the proportions of incident cases by injecting drug user were 48.9%, 47.2% and 46.7% respectively during this period. Moreover, the Workbook method has shown that, among adults living with HIV in 2007, 50.3% were infected through injecting drugs and 48.4% through unsafe sexual activity.

CONCLUSIONThe rapid rise in HIV infections through injecting drug in Dehong prefecture has been initially curbed. HIV epidemic has already witnessed a change from predominantly through drug injecting-related activity to an almost equally fuelled epidemic by sexual and drug-related transmission.

Objective:To observe the effect of Jiajian Fuyuan Huoxuetang combined with electroacupuncture on neurological rehabilitation of patients with spinal cord injury, and to investigate its effect on neurotrophic and inflammatory factors. Method:One hundred and twenty patients were randomly divided into control group (59 cases) and observation group (61 cases) by random number table. Both groups’ patients got monosialotetrahexosylganglioside by intravenous drip for 6 weeks, 200-400 mg/time, 1 time/day.Rat nerve growth factor for injection by intramuscular injection for 4 weeks, 20 μg/time, 1 time/day. Patients in control group additionally got electroacupuncture treatment,and tongluo huatan capsule,3 caps/time,3 time/days. The patients in observation group additionally got Jiajian Fuyuan Huoxuetang combined with electroacupuncture, 1 dose/day. The courses of treatment were 12 weeks in two groups. Scores of degree of spinal cord neurological impairment were graded by using impairment score of American Spinal Injury Association (ASIA). Lower extremity motor ability was discussed by using the walking index of spinal cord injuryⅡ (WISCⅠ Ⅱ) and 10 minutes’ walking time (10 MWT). Before and after treatment, functions of daily life were evaluated by using Barthel index (MBI). Bladder function was also discussed, and levels of brain-derived nerve growth factor in peripheral blood (BDNF), nerve growth factor (NGF), astrogenic calcium binding protein S-100 β (S-100 β), tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) were also detected. Result:After the treatment, scores of sensory and motor in ASIA scale in observation group were all higher than those in control group (P<0.01). Score of WISCⅠ Ⅱ in observation group was higher than that in control group, and 10 MWT was shorter than that in control group (P<0.01). Times of leakage of urine, urinary incontinence volume and residual urine volume were all less than those in control group, and bladder volume was more than that in control group (P<0.01). Functions of daily life in observation group were better than those in control group (Z=1.967, P<0.05), and the levels of BDNF and NGF were higher than those in control group, while levels of S-100 β, TNF-α and IL-1β were lower than those in control group (P<0.01). Conclusion:On the basis of routine comprehensive rehabilitation therapy of western medicine, Jiajian Fuyuan Huoxuetang combined with electroacupuncture can promote the recovery of nervous function, improve sensory and motor function, improve bladder function and daily living ability, and promote the expression of neurotrophic factors and inhibit inflammatory reaction in neurological rehabilitation for the patients with spinal cord injury.
