OBJECTIVETo observe the therapeutic efficacy of combined therapy with ginsenosides (GS) and prednisone on systemic lupus erythematosus (SLE).

METHODSSixty patients with SLE were assigned to 2 groups randomly by a randomizing digital table, the treated group and the control group, 30 cases in each group. All patients were treated with routine administration of prednisone, but to the treated group GS Capsule (50 mg) was given additionally twice every day, while to the control group placebo capsule of equal dosage was given instead. The total clinical efficacy, and changes of systemic lupus erythematosus disease activity index (SLEDAI), erythrocyte sedimentation rate (ESR), complement 3 (C3) and anti-ds-DNA were observed after 3-month-treatment.

RESULTSThe total clinical efficacy rate was 89.28% in the treated group and 66.67% in the control group, showing a significant difference between them (P<0.05). The improvements of SLEDAI, ESR and C3 in the treated group were more significant than those in the control group (P<0.01, P<0.05).

CONCLUSIONThe combined therapy of GS and prednisone could enhance the clinical efficacy, reduce the SLEDAI and promote the recovery of laboratory indices in SLE patients.

The dynamic changes of germination percentage, germination potential, thousand-seed weight, antioxidase activity in Desmodium styracifolium seeds with different storage time were tested, and electrical conductivity, contents of soluble sugar, soluble protein, starch in seed leach liquor were also determined in order to reveal the mechanism of seed deterioration. The results as the following. (1) The germination percentage, germination potential and thousand-seed weight of D. styracifolium seeds declined, while the seed coat color darkened with the extension of storage time. (2) The activities of superoxide dismutase (SOD) and peroxidase (POD) decreased with the prolongation of storage period. The SOD activity declined fastest in 1,095-1,185 d of storage, while the POD activity declined significantly in 365-395 d of storage. (3) The electrical conductivity and the contents of soluble sugar, starch in seed leach liquor increased, while the content of soluble protein declined with the extension of storage time. (4) Correlation analysis indicated that the germination percentage, germination potential and thousand-seed weight of D. styracifolium seeds have a significantly positive correlation with SOD and POD activity, while have a significantly negative correlation with the electrical conductivity, contents of soluble sugar and starch. It can be concluded that during the storage of D. styracifolium seeds, physiological and biochemical changes including decrease in antioxidase activity, rise in electrical conductivity, degradation effluent of soluble sugar and starch, degradation of soluble protein were the main factors leading to the seed deterioration.

OBJECTIVETo study whether ginsenoside (GS) can regulate the glucocorticoid receptor (GR) in mice with ischemic liver damage, and to preliminarily observe its dose-effect relationship for providing an experimental bases in seeking a new way to relieve the damage from view of GR.

METHODSAdult male SD mouse was used to establish liver ischemia model, and different doses (100, 50, and 25 mg/kg) of GS was given via gastric infusion before modeling. The maximal GR binding capacity (Bmax) of liver and the level of GR mRNA expression in liver were dynamically determined at various time points (2 h, 6 h, 12 h and 24 h) after modeling.

RESULTSCompared with the normal control group, GR Bmax and GR mRNA expression in model rats were lower obviously (P < 0.01). As compared with the control group, GR Bmax and GR mRNA expression in model rats treated with 50 mg/kg GS significantly raised at 2 h, 6 h, 12 h (P < 0.01), while the changes in modeling rats treated with other two doses of GS were of no statistical significance.

CONCLUSIONGS in dose of 50 mg/kg can elevate the GR Bmax of liver and the level of GR mRNA expression in liver of rats with ischemic damage.

OBJECTIVETo find out the risk factors of drowning among children aged 1 and 14 in rural areas and to provide evidence for prevention and to reduce such incidents.

METHODS20 towns being selected as a cluster sampling study and screened out 133 drowning children aged 1-14 from Jan. 1, 2002 to Dec. 31, 2004 were screened. 1:2 matched case-control method was conducted. Data was analyzed with conditional univariate and multivariate logistic regression analysis.

RESULTSResults showed that falling into water took the leading type of drowning among children from the rural areas. The component of drowning displayed that boys was higher than girls. The majority occurred. during the warmer months, in summer and autumn. The places where drowning occurred was mainly at incidence site. Results from single and multiple factors analysis identified four major risk factors as: alcoholic drinking of his/her mother, lack of emergency treatment in the village, the child care-taker did not know what to do when drowning was occurring, the child usually played beside the water site. Factors preventing from drowning were: swimming training, the child caretaker keeping an eye on the child when he/she was swimming, the health condition of the caretaker and the communication with the parents.

CONCLUSIONThe risk factors of drowning among children aged 1-14 in rural areas were caused by multiple factors. Prevention and control program on drowning should be focusing on supervision, safety water, safety education and teaching swimming.

Malignant tumors are one of the leading causes of death in the world. Considerable progresses have been made on the treatment of tumors in recent decades, especially in the prevention, early diagnosis and the model changing of therapeutics. But we are still facing tough challenges, including the increasing treatment burden and limited improvement of efficacy. In China, Chinese medicine (CM) provides a powerful arsenal to fight against tumors. CM can be well applied to the onset and progression of tumors in China, bearing the characteristics of multi-target, multi-phase and multi-effect. But there are also many problems demanding urgent attention in the use of CM. Some most debated problems in this field were summarized. We should upgrade our concepts in using CM, find its position scientifically, and establish evidence of its effect by high quality clinical research.

Objective To study the influence of fluoride on the expression of osteoprotegerin(OPG) mRNA and protein in suckling rat osteoblasts. Methods Osteoblasts obtained from calvarial of suckling Wistar rats were cultured in vitro in the media supplemented with NaF at a series of doses[O(control), 1,2 and 4 mg/L groups], and OPG mRNA expression and protein were evaluated by RT-PCR and ELISA methods, respectively. Results OPG mRNA expression in suckling rat osteoblasts cultured in vitro significantly increased after exposure to NaF for 48 h and 72 h(F=333.48,808.34,P<0.05). OPG mRNA expression in suckling rat osteoblasts cultured in vitro after exposure to NaF for 48 h at different doses(0.810±0.003, 0.819±0.031 and 0.870±0.044 for 1,2 and 4 mg/L groups, respectively) compared with that of control (0.800±0.040, all P<0.05). OPG mRNA expression further increased for 72 h exposure to NaF(0.933±0.047,1.031±0.051,1.240±0.062 for 1,2 and 4 mg/L, respectively), significantly higher than that of the control (0.805±0.020,all P<0.05) and corresponding groups at 48 h. NaF doses and time exposure exhibited a significant synergistic effect on OPG mRNA expression(F=2004.16, P<0.05). NaF also enhanced OPG protein expression in suckling rat osteoblasts cultured in vitro. Significant differences were observed only in 4 mg/L group(0.228±0.014,0.277±0.048) and control(0.205±0.012,0.229±0.010) at 48 h and 72 h (P<0.05). In addition, OPG protein expression at 72 h post-exposure was higher than that at 48 h,but there was no synergistic effect between concentration and time(F=1.21,P>0.05). Conclusions The results suggested that NaF could increase OPG mRNA and protein expression in suckling rat osteoblasts with a synergistic effect between the doses and exposure time.
