OBJECTIVE:To promote the standardization of the packing inserts of Chinese traditional patent medicine in the writing and printing. METHODS: A total of 106 package inserts of 5 common dosage forms of Chinese traditional patent medicine analyzed in accordance with the national standard. RESULTS: Problems were found in most of the package inserts of Chinese traditional patent medicine, which manifested as chaotic ranking of essential components, non-standard stating of actions and indications, unclear stating about dosage and administration, nonobjective in the labeling of adverse drug reactions, confusion between contraindication and precautions, lacking of research document on drug interactions, pharmacology & toxicology and pharmacokinetics. CONCLUSION:The drug surveilance agency should attach importance to and tighten control on the nonstandard writing and printing of packing inserts of Chinese traditional patent medicine.

Objective Poly (ADP-ribose) polymerase (PARP) have been demonstrated to play an important role in systemic lupus erythematosus (SLE). In this study we assessed the expression of PARP on peripheral blood mononuclear cells with active or inacte SLE and tried to investigate the relationship between PARP and cell apoptosis on SLE. Methods Thirty definitive SLE patients and 10 healthy controls were enrolled. PBMC were separated from the peripheral blood samples. Western blot technique was applied to analyze the expression of PARP. Flow cytometry were applied to analyze the cell apoptosis. T test were used. Results The cell apoptosis in active patients with SLE was significantly higher than that of inactive patients with SLE and normal controls (the t values were 4.83 and 5.05 respectively, P<0.05). The level of PARP expression was significantly decreased in active patients with SLE as compared with controls and inactive patients with SLE (the t values were 7.66 and 7.07 respectively, P<0.05). At the same time, the cleavage fragment of PARP increased in active patients. Conclusion The results suggest that PARP may be involved in the pathogenesis of SLE and the expression level may be a good indicator for disease activity of SLE . Decrease of PARP may promote the occurrence and development of SLE. In addition, PARP may play a certain role in adjusting cell apoptosis in patients with SLE.

Objective To explore the expression of Akt in peripheral blood mononuclear cells (PBMCs) and its regulatory role on its downstream molecules forkhead box transcription factor O1 (FOXO1) and Bim in patients with systemic lupus erythematosus (SLE).The role of Akt/FOXO1/Bim signaling pathway on PBMCs apoptosis was clarified.Methods Sixty-three SLE patients and 23 healthy controls were enrolled.PBMC were separated from the peripheral blood specimen.Western blot technique was applied to analyze the expression of Akt,FOXO1 and Bim.Flow cytometry was applied to analyze PBMCs apoptosis.The t-test was used for statistical analysis.Results The apoptosis of PBMCs in patients with active SLE [(16.3±4.0)％] was significantly higher than that of patients with inactive SLE [(5.6 ±2.9)％] and normal controls [(5.2 ±4.2)％,t=4.83,5.05;P＜0.05].The levels of phosphorylation of Akt,FOXO1 and Bim expression was significantly decreased in patients with active SLE as compared with controls and patients with inactive SLE (P＜0.05).However,these indicators had no significant difference between the controls and patients with inactive SLE (P＞0.05).Conclusion ① The results of this study suggest that the expression level of Akt may be a good indicator for disease activity of SLE.Decrease of Akt may promote the occurrence and development of SLE.② Akt activity decline may lead to increased apoptosis of PBMCs.In this process,Akt may regulate its downstream FOXO1 and Bim phosphorylation levels which can enhance their ability to pro-apoptotic.

ObjectiveTo study the prevalence rate of post-stroke depression (PSD) of the elderly in the community and analyze risk factors of them. MethodsThe elders of the age of 60 or over were sampled as subjects from a community. Zung (SDS) was used as screening instruments and Hamilton rating scale for depression (HRSD-24) as evaluating scales. The prevalence rate of PSD was surveyed. A structured questionnaire was used and physical examination was carried out. Risk factors measured included baseline information, daily habits, and history of main diseases (hypertension, coronary heart disease, diabetes mellitus, myocardial infarction, and so on). The relationship between risk factors and PSD was analyzed.ResultsThe prevalence of PSD was 9.5%. The risk factors for PSD were life quality and age. ConclusionPost-stroke depression disturbs elder's health and rehabilitation. The prevalence rate and harm of PSD are higher than depression without stroke.

Objective To observe the effects of Qingjin Huatan Decoction on EGFR/MAPK signaling pathway of airway mucus hypersecretion rats with chronic obstructive pulmonary disease (COPD). Methods Intratracheal instillation of LPS combined with smudging method was used to establish COPD airway mucus hypersecretion rat models. Experimental rats were randomly divided into blank group, model group, Qingjin Huatan Decoction group and clarithromycin group.

Objective To systematically evaluate the efficacy of acupotomy treatment for the stenosing tenovaginitis of flexor digitorum.Methods Articles about RCTs of acupotomy treatment and local blocking for the treatment of stenosing tenovaginitis of flexor digitorum were retrieved from CBM, CNKI, VIP, Wanfang database, PubMed, Embase, and Cochrane library. And then according to the requirement of Cochrane Handbook for Systemetic Reviews 5.1.0, two reviewers independently chose tests, extracted data, had a cross check, accessed methodological qualities and finally used RevMan 5.3 software for Meta analysis. The total effective rate, cure rate and improvement rate of acupotomy treatment and local blocking in treating stenosing tenovaginitis of flexor digitorum were assessed by using odds ratio (OR).Results Totally 10 articles involving 1426 cases were included. The cure rate in acupotomy treatment group was higher than that of local blocking group [OR=13.11 (95% CI: 8.23–20.89),Z=10.83 (P<0.000 01)], funnel plot Begg’s testP=0.858, Egger’s testP=0.579; the improvement rate of local blocking rate was higher than that of acupotomy treatment group [OR=0.14 (95% CI: 0.10–0.19),Z=11.60 (P<0.000 01)], funnel plot Begg’s test P=1.000, Egger’s testP=0.926; the total effective rate of acupotomy treatment group was higher than that of local blocking group [OR=18.26 (95% CI: 9.95–33.50),Z=9.38 (P<0.000 01)], funnel plot Begg’s testP=0.592, Egger’s testP=0.936.Conclusion Acupotomy treatment for stenosing tenovaginitis of flexor digitorum is superior to local blocking injection. However, the quality of the RCTs is low, so more large-sample, multi-center, and high-quality clinical RCTs are required for further verification.

Objective To study the expression of transcription factor FOXO1 and FOXO3a on peripheral blood mononuclear cells (PBMC) in patients with active or inactive systemic lupus erythematosus (SLE) and investigate the effect of FOXO1 and FOXO3a on the clinical features of SLE. Methods Thirty SLE patients and 10 healthy controls were enrolled. PBMC were separated from the peripheral blood. Reverse transcription-polymerase chain reaction (RT-PCR) and western blot were applied to analyze the expression of FOXOI and FOXO3a. Results The level of FOXO1 expression was significantly decreased in active SLE patients compared with controls and patients with inactive SLE (P<0.05). The level of FOXO1 expression in inactive SLE patients was lower than that of the controls (P<0.05). The expression of FOXO1 mRNA was negatively correlated to SLEDAI. However, the level of FOXO3a was similar among the three groups. Conclusion The result suggests that FOXO1 may be involved in the pathogenesis of SLE and the expression level of FOXOI may be a good indicator for the disease activity of SLE.

BACKGROUND: Peripheral nerve injuries are hoped to promote the regeneration of nerve repair by elevating brain-derived neurotrophic factor (BDNF) concentration in local injury regions. OBJECTIVE: To observe the recanalization of nerve fiber and motor function in sciatic nerve injury rats following BDNF gene-modified bone marrow mesenchymal stem cells (BMSCs). DESIGN, TIME AND SETTING: The randomized, controlled animal study was performed at the Fujian Institute of Neurology from May 2007 to May 2008. MATERIALS: Femur and tibia of F344 male rats aged 2 months were sterilely harvested to prepare BMSCs. BDNF gene-modified BMSCs were prepared using constructed chronic viral vector PNL-BDNF-IRES2-EGFP. METHODS: The right sciatic nerve injury models were made using 60 adult Sprague Dawley rats. All models were randomly assigned into phosphate buffer saline (PBS) group, BMSC group and BDNF gene-modified BMSC group. 2 ?L BPS, 2 ?L BMSC solution and 2 ?L BDNF modified BMSC solution were separately transfered into injury site of each group. MAIN OUTCOME MEASURES: The retrograde horseradish peroxidase tracing was practiced to observe neural cell number in the Lumbar 4 and 5 spinal cord anterior horn at 2 and 4 weeks after microinjection. Sciatic nerve function index was used to observe rat motor function of injured limbs. Fluorescence excitation and immunohistochemistry were employed to detect BMSC survival and BDNF expression. RESULTS: Cell number was more, and nerve function recovery was better in the Lumbar 4 and 5 spinal cord anterior horn in the BDNF gene-modified BMSC group than in the PBS and BMSC groups. BMSC survival was found in the injured sites in the BMSC and BDNF gene-modified BMSC groups. BDNF expression was significantly more in the BDNF gene-modified BMSC group than in the BMSC group. CONCLUSION: BDNF gene-modified BMSCs have promotion effects on the recanalization and functional recovery of nerve fiber following peripheral nerve injury.
