Objective: To investigate the effect of matrine (Ma) on telomerase activity and cell cycle in hepatoma cell line HepG 2 cells. Methods: TRAP ELISA method was used to determine the telomerase activity in HepG 2 cells which were treated with different concentrations of Ma. Plasmid inserted with 800 bp of the human telomerase reverse transcriptase (hTERT) promoter was transiently transfected into HepG 2 cells by lipofect. Different concentrations of Ma were added into culture media 2 h later, and the activity of the hTERT promoter was tested 48 h after transfection. In addition, the percentages of HepG 2 cells in different cell cycle were determined by the flow cytometry on the 24, 48 and 72 h respectively after adding the different concentrations of Ma. Results: The telomerase activity of HepG 2 was suppressed by Ma at the dose of 750 ?g/ml and the expression of hTERT promoter was also inhibited. The percentage of G 0/G 1 stage cells increased and the percentage of S and G 2/M stages cells decreased in both 500 ?g /ml and 750 ?g /ml groups 48 and 72 h after Ma was added. Conclusion: Ma may have inhibitory effect on hTERT promoter expression, which is related to the telomerase activity and cell cycle regulation.

Objective:To explore the independent prognostic factors of primary osteosarcoma patients under 20 years old after radical surgery, so as to predict the prognosis and survival of patients.Methods:The clinicopathological data of 1 339 patients with primary osteosarcoma diagnosed and registered in the National Cancer Institute Surveillance, epidemiology and outcome database (SEER) from 1984 to 2014 were retrospectively analyzed. Kaplan Meier method was used to calculate the survival rate of patients. Log rank test was used to evaluate the survival difference. Cox multivariate analysis was used to determine the independent prognostic factors of osteosarcoma after radical surgery factor.Results:The results of primary osteosarcoma patients undergoing radical surgery found that 34 cases (2.54%) aged 0-5 years old, 236 cases (17.63%) aged 6-10 years old, and 600 cases (44.81%) aged 11-15 years old and 469 cases (35.02%) aged 16-20 years old. The median survival time was 68 months. Among them, 757(56.53%) were male and 582(43.47%) were female. Among the 1 339 cases, 986 were white (73.64%), followed by black 230(17.18%), and 123 other races (9.18%). Multivariate analysis revealed that males ( HR=1.242; 95% CI:1.024-1.505), axial osteosarcoma ( HR=1.589; 95% CI:1.179-2.166), and regional invasion of osteosarcoma ( HR=1.470; 95% CI:1.156-1.870), distant metastasis ( HR=3.536; 95% CI:2.725-4.589) were independent risk factors for overall survival. Other types of osteosarcoma ( HR=0.471; 95% CI:0.285-0.779) were independent protective factors for overall survival. Conclusions:Based on the SEER database, this study identified independent prognostic factors for patients with primary osteosarcoma under the age of 20 who underwent radical surgery, which will help clinicians formulate individualized medical strategies and predict patients′ prognosis.

Objective: To analyze associations of MRI-lesions and clinical features with disability in patients
with multiple sclerosis (MS) in Shanghai, China. Methods: We studied patients with MS, identified
from a survey in Shanghai, whose sites of lesions in the CNS was based on the MRI examinations.
Associations between MRI-lesions, various clinical variables and the severity of disability were analyzed
with univariate and multivariate logistic regression analysis. Results: There were 210 patients in this
study. The disability of the patients with lesions confined to the spinal cord was significantly more
severe than those with lesions in the brain (p < 0.008). Current age (OR: 1.041, 95% CI: 1.007~1.077),
MS duration (OR: 1.082, 95% CI: 1.011~1.159) and MRI-lesions in the spinal cord (OR: 2.441, 95%
CI: 1.039~5.737) were significantly associated with severity of disability on multivariate logistic
regression analysis.
Conclusion: MRI-lesions in the spinal cord, older age, a longer MS duration were significantly
associated with a more severe disability in this MS study in Shanghai China.

To confirm the effect of SS-cream, which was based on the traditional Chinese Royal herb remedy including 8 oriental herb combinations, 43 out of 150 patients with premature ejaculation (PE) were selected and investigated for a double-blind clinical trial between Nov. 1993 and Feb. l994. There mean age was 41.4 years. The 28 patients complained of PE only but 15 had concurrent mild psychogenic impotence. Only 20% of their spouse was satisfied for sexual lives. The packages of SS-cream and controls such as 1.25% (LL), 5%(ML) and 10%(HL) lidocaine cream were made similarly as much as 0.2g. They were randomly divided into the 5 groups. Each patient was assigned to apply LL, ML or SS cream once a weak for 4 consecutive weeks as scheduled. A within subjects comparison of pre and post application for ejaculation time and spouse's satisfaction was investigated. The applied groups such as LL, ML and HL cream were not effective. After SS-cream application, ejaculation time was delayed upto mean 11.3min. in 40(93%) and most of them with PE only as well as PE associated with impotence were satisfied. These data suggest that SS-cream is effective in treating PE as well as PE with mild impotence.

This study investigated the effect of arctigenin (Arc) on the cell activation, cytokines expression, proliferation, and cell-cycle distribution of mouse T lymphocytes. Mouse lymphocytes were prepared from lymph node and treated with Phorbol-12-myristate-13-acetate (PMA)/Ionimycin (Ion) and/or Arc. CD69, CD25, cytokines, proliferation and cell cycle were assayed by flow cytometry. The results showed that, at concentrations of less than 1.00 micromol x L(-1), Arc expressed non-obvious cell damage to cultured lymphocytes, however, it could significantly down-regulate the expression of CD69 and CD25, as well as TNF-alpha, IFN-gamma, IL-2, IL-4, IL-6 and IL-10 on PMA/Ion stimulated lymphocytes. At the same time, Arc could also inhibit the proliferation of PMA/Ion-activated lymphocytes and exhibited lymphocyte G 0/G1 phase cycle arrest. These results suggest that Arc possesses significant anti-inflammatory effects that may be mediated through the regulation of cell activation, cytokines expression and cell proliferation.

OBJECTIVETo explore the efficacy and feasibility of dog days moxibustion plaster therapy in treatment of allergic rhinitis of different patterns/syndromes.
METHODSAllergic rhinitis of lung deficiency and invasion of cold, spleen qi deficiency and kidney yang deficiency, 56 patients for each pattern/syndrome were randomized into a plaster therapy group and a nasal spray group, 28 cases in each one. In the plaster therapy group, according to the pattern/syndrome differentiation, with literature retrieval method, 3 acupoints of high frequency utility in clinic were selected as one group in acupoint plaster therapy. For lung deficiency and invasion of cold pattern/syndrome, Feishu (BL 13), Fengmen (BL 12) and Hegu (LI 4) were selected. For spleen qi deficiency pattern/syndrome, Pishu (BL 21), Zusanli (ST 36) and Dazhui (GV 14) were selected. For kidney yang deficiency pattern/ syndrome, Shenshu (BL 23), Dingchuan (EX-B 1) and Bailao (EX-HN 15) were selected. Separately, on July 13, 2013, July 23, 2013, August 2, 2013 and August 12, 2013, the aucpoint plaster therapy was applied, 2 to 4 h (1 to 2 h for children) each time. In the nasal spray group, beclometasone dipropionate aqueous nasal spray, 2 presses one nostril each time, 2 to 3 times a day, continuously for 4 weeks. The symptom score and efficacy were compared before and after treatment in the patients of the two groups.
RESULTSThe symptom scores of 3 patterns/syndromes were all apparently improved after treatment as compared with those before treatment in the patients of the two groups (all P<0.05), and the result in the plaster therapy group was better than that of the nasal spray group (P<0.05, P<0.01). For lung deficiency and invasion of cold pattern/syndrome, the total effective rate was 87.3% (20/24) in the plaster therapy group, better than 84.6% (22/26) in the nasal spray group (P<0.05). For spleen qi deficiency pattern/syndrome, the total effective rate was 83.3% (20/24) in the plaster therapy group, obviously better than 76.9% (22/26) in the nasal spray group (P<0.05). For kidney yang deficiency pattern/syndrome, the total effective rate was 79.2% (19/24) in the plaster therapy group, better than 76.9% (22/26) in the nasal spray group (P<0.05).
CONCLUSIONThe dog days moxibustion plaster therapy achieves definite efficacy on allergic rhinitis at the acupoints selected based on the differentiation of different patterns/syndromes and the efficacy is better than beclometasone dipropionate aqueous nasal spray.
