Traditional Chinese ancient prescriptions have been used for treatment of liver cancer for a long history and the scientific and rational compatibility is a great wealth for modern research and development (R&D) of new drugs. The research and development of new drugs are often accompanied with a large investment, a long cycle and a high risk, especially for the anti-tumor drugs R&D which are facing more risks and lower successful rate. In this research, the regularity of compatibility of drugs was analyzed from 124 anti-hepatoma ancient prescriptions by computer program. The results can offer help to the R&D of anti-hepatoma new drugs and reduce the risk of drug screening. In addition, we surveyed 22 companies in this field from six provinces such as Beijing, Shanghai, Tianjin and so on and obtained 240 risk assessment questionaires. Then we used qualitative analysis method to interpret the greatest impacts for the risks in the process of R&D, production and sales of anti-hepatoma new drugs. The study provides a basis for anti-liver cancer drugs R&D researchers, who can take effective measures to reduce the R&D risks and improve successful rate.

Objective To examine the changes of serum total and high density lipoprotein cholesterol during whole blood incubation and to investigate the possible mechanisms responsible for the instability.Methods A method for the measurement of serum total cholesterol (TC), total free cholesterol (TFC), high density lipoprotein cholesterol (HDLC) and high density lipoprotein free cholesterol (HDLFC) by high performance liquid chromatography (HPLC) was developed. Whole blood specimens were incubated at 25℃ and 4℃ for various period of time and serum TC, TFC, HDLC and HDLFC were measured.Results The new HPLC method showed a mean within-run CV of 0.22%~0.51%. The averaged changes during the incubations ranged 0.6%~2.0% for TC and 2.0%~4.1% for HDLC.Conclusion An HPLC method has been established that is highly precise and can be used for detecting subtle cholesterol changes in biological samples. Different cholesterol exchanges or transfers between blood cells and lipoproteins exist during various incubations. Prolonged whole blood storage that causes serum TC and HDLC changes should be avoided in clinical lipid measurements.

OBJECTIVETo explore therapeutic effect and action mechanism of regulating spleen-stomach needling on diabetic nephropathy (DN).

METHODSUsing multi-centric, randomized, controlled and blind principles, 144 cases of DN were divided into an observation group and a control group according to random digital tab, 72 cases in each one. Based on regular treatment of diabetes, the regulating spleen-stomach needling was applied at Zhongwan (CV 12), Quchi (LI 11), Hegu (LI 4) and Xuehai (SP 10), etc. in the observation group while Shenshu (BL 23), Taixi (KI 3), Sanyinjiao (SP 6), Yanglingquan (GB 34), etc. were selected in the control group by reference of Acupuncture and moxibustion. The treatment was given twice a day, six days as a treatment session with interval of one day between sessions. Totally six weeks were required. Changes of clinical symptoms and signs, fast blood glucose (FBG), urinary albumin excretion rate (UAER), beta2-microglobulin (beta2-MG), monocyte chemotactic protein-1 (MCP-1), lymphocyte membrane cholesterol, propanediol (MDA), PCO, 8-hydroxydeoxy guanosine (8-OHdG), superoxide dismutase (SOD), CD3+, CD4+, CD8+, and CD4+/CD8+ were observed before and after treatment in two groups.

RESULTSAs for improving clinical symptoms and signs, total effective rate was 84.29% (59/70) in the observation group and 55.56% (40/72) in the control group, which had statistical difference between two groups (P<0.01). As for regulating glycometabolism [(6.25 +/- 0.32) mmol/L vs (8.09 +/- 0.63) mmol/L], reducing UAER [(154.43 +/- 55.14) mg/24h vs (268.91 +/- 77.65) mg/24h], restraining over-expression of MCP-1 [(137.59 +/- 36.15) pg/mL vs (166.89 +/- 42.82) pg/mL], regulating level of oxidative stress, prohibiting oxidation of protein and adjusting quantity and activity of T lymphocyte subgroup, the observation group was superior to the control group (P< 0.05, P<0.01).

CONCLUSIONThe regulating spleen-stomach needling is an effective method for treatment of DN, which cold improve glycometabolism disturbance-induced progressive kidney injury, recover glomerular filtration, reduce urinary albumin excretion rate, restrain overexpression of MCP-1, adjust level of oxidative stress, prohibit oxidation of protein, increase protectiveness of membrane, adjust quantity and activity abnormity of T lymphocyte subgroup, leading to repairing lymphocyte damage and improving immune expression to delay kidney damage.

Purpose To study the malignant transformation after treating rat oval cell line ( WB-F344 ) with chemical carcinogen N-methyl-N′-nitro-N-nitrosoguanidine ( MNNG) . Methods WB-F344 cells were cultured with MNNG for severe times. The biological characteristics of induced cells were detected through the following methods:to check proliferation activity by flow cytometry analysis, to examine malignant transformation degree of induced cells by soft agar assay and tumor formation in NOD/SCID mice, and to investi-gate the transcriptional and protein levels of hepatocellular carcinoma marker GGT, GST-P by real time-PCR. Results Oval cells in-duced by MNNG showed changes in biological characteristics and malignant molecular markers. Conclusion Hepatic oval cells model is successfully established, which can be confirmed by tumor formation in NOD/SCID mice.

Objective To observe the cost-effectiveness of using continuous subcutaneous insulin infusion (CS Ⅱ) and multi-point daily insulin injections (MDI) in controlling blood sugar in the newly hospitalized type 2 diabetes patients. Methods Retrospective analysis on 86 cases taking CS Ⅱ and 103 cases using MDI on a 'blood sugar control program' among the newly hospitalized patients with type 2 diabetes. The period for observation was 2 weeks, using cost-effectiveness analysis methods to evaluate the two treatment programs. Results After two weeks of treatment, the effectiveness in the control of blood sugar in CS Ⅱ group was similar to the MDI group, with no significant difference(P<0.05) and the adverse reactions were similar. Costs in the CS Ⅱ program (Yuan/person) was less than in the MDI program (1478.34 vs. 1620.46), with significant differences (P< 0.05). The cost-effectiveness ratios (C/E) were 15.07 in the CS Ⅱ group, and 16.34 in the MDI group, with no significant difference (P>0.05). In order to further reduce the cost of CS Ⅱ group as a reference, the incremental cost-effectiveness ratio (△C/ △E)ofthe MDI group was 129.20. Conclusion Costs-effective of the CS Ⅱ program was better than the MDI one in treating the newly hospitalized patients with type 2 diabetes, suggesting that CS Ⅱ program might be a better choice for hospitals to carry on an intensive insulin therapy program.

Currently, chemotherapy is one of the main therapy for cancer. But the traditional antitumor drugs are systemic distribution in vivo, they are difficult to achieve an effective drug concentration in the tumor tissue and don't have the ability to distinguish normal cells and tumor cells by themselves, that cause systemic toxicity easily and can not meet the clinical needs. With the research on mesoporous silica nanoparticles (MSNs) deepening, more and more attention in the drug delivery system have been payed to in recent years, because of its unique physicochemical structure characteristics, it has the effect on specific targets, directly inhibits the tumor cell growth, reduces the side effects to normal cells, tissues and organs and can be long-term medication, etc. It is expected to be excellent carriers of antitumor drugs. MSNs application in the field of cancer treatment has now become a hot research field of medicine. In this paper, the latest research about MSNs in antitumor drugs targeting delivery system from 2008 to 2015 is summarized, including the application of MSNs separately in antitumor drug targeting, passive targeting, active targeting, physical or chemical conditions response targeting and other compound targeting drug delivery system. We expect it to provide a reference to the toxicity reducing and efficacy enhancing and further development of chemical medicine, natural medicine and monomeric compound of chinese herbal medicine.
