In this study, efforts were made to collect 88 traditional Chinese medicine (TCM) prescriptions for treating ADHD from public literatures, establish a medication database and conduct data mining on the efficacy, properties, tastes, meridian entries and compatibility regularity of TCMs by using frequency analysis, association rules analysis and cluster analysis. The results showed 33 herbs with a high frequency (≥ 10%). The top 12 frequently applied ADHD herbs were respectively Acori Tatarinowii Rhizome, Polygalae Radix, Prepared Rehmanniae Radix, Os Draconis, Glycyrrhizae Radix et Rhizome, Poria, Concha Ostreae, Testudinis Carapacis et Plastri, Paeoniae Alba Radix, Schisandrae Fructus Chinensis, Fructus Corni, Dioscoreae Rhizoma. The top seven types of frequently applied ADHD herbs by effect were respectively tonic herb, sedative herbs, livei-wind calming herbs, heat clearing herbs, astringent herbs, awaking herbs and damp clearing and diuresis promoting herbs. The top three properties were warm, cold and neutral, with warm as the dominance. The top three tastes were sweetness, bitterness and acridity, with sweetness as the dominance. The top three meridian entries were liver meridian, heart meridian and kidney meridian. The association rules analysis showed commonly used herbal pairs. Polygalae Radix-Acori Tatarinowii Rhizome, Concha Ostreae-Os Draconis, Prepared Rehmanniae Radix-Fructus Corni-Os Draconis. Eight highly frequent cluster prescriptions were summarized based on the cluster analysis. This study indicates that basic TCM prescriptions for treating ADHD were principally composed of tonics (nourishing liver and kidney, invigorating heart and spleen) and tranquilization, which were supplemented with herbs for calming liver, clearing heat, promoting qi-circulation, promoting blood-circulation, reducing phlegm and calming endogenous wind. The combination of multiple data mining techniques can reflect the clinical medication regularity of herbs for treating ADHD in an overall and objective manner.

BACKGROUND: Adequate preparation of donors and recipients prior to living-related donor renal transplantation, short warm and cold ischemia time for donor kidney, good histocompatibility of human leukocyte antigen match, and low postoperative rejection incidence provide feasibility for use of low-dose immunosuppressive agents after living-related donor renal transplantation. OBJECTIVE: To investigate the safety and effectiveness of low-dose calcineurin inhibitors (CNI), an immunosuppressive agent, in living-related donor renal transplantation. METHODS: A total of 38 recipients who underwent living-related donor renal transplantation at the Center of Renal Transplantation of the First Affiliated Hospital of Nanjing Medical University from January 2006 to June 2008 were randomized for treatment with mycophenolate mofetil (750 mg twice a day), prednisone, and either standard-dose CNI (n=18) or low-dose CNI (n=20) during 12 months post-transplantation. Ciclosporin A was given orally (starting dose, 6 and 4 mg/kg per day, respectively) in two divided doses to achieve the 12-hour whole blood concentration as measured by fluorescence polarization immunoassay. The starting dose of tacrolimus was 0.12 and 0.08 mg/kg per day respectively, and its whole blood concentration was measured by enzyme-multiplied immunoassay technique. After transplantation, patients were followed up. Renal function, pulmonary infection, liver dysfunction, and CNI nephrotoxicity at different time periods were compared between different regimens. RESULTS AND CONCLUSION: During 12 months post-transplantation, patient death occurred in one of 18 patients (5.6%) in the CNI standard-dose group and none of 20 patients (0%) in the CNI low-dose group. There was no significant difference in renal function and acute rejection between CNI standard-dose and CNI low-dose groups (P > 0.05). The incidence of liver dysfunction and CNI nephrotoxicity was significantly lower in the CNI low-dose group than in the CNI standard-dose group (P < 0.05). In addition, a low-dose CNI regimen helped recipients to lessen the economic burdens. These findings indicate that it is effective, safe and economical to use a low-dose CNI regimen in living-related donor renal transplantation.

″Herb-Pairs″, also known as pair drugs, refers to a prescription consisted of two relatively fixed traditional Chinese medicine, is the most basic, most simple and most common form of medication prescription in traditional Chinese medicine compound compatibility. It is not a random combination of two herbs, nor is the simple accumulation of efficacy, but the simple and delicate experience of ancient Chinese medicine practitioners. As a bridge between single drug and prescriptions, it is the embodiment of the regular and dialectical connotation. Therefore, research on Herb-Pairs has always been the most basic and most important entry point for compound compatibility studies. However, the interaction between herbs and herbs is an effect with a downside as well as benefits. The beneficial herb-herb interaction in Herb-Pairs include mutual promotion, mutual enhancement, mutual restraint between two drugs and counteract toxicity of another drug. And the harmful herb- herb interaction in Herb- Pairs includes mutual inhibition and antagonism. All of these interactions areby means of affecting the metabolism of components to play a therapeutic effect. Using the pharmacokinetic-pharmacodynamic (PK-PD) binding model, the combination of drug metabolism and pharmacodynamics can further elucidate the influence on effect caused by drug concentration and metabolism, which can help elucidate the mechanism of drug action. Consequently, in this review, the herb-herb interactions in terms of pharmacokinetic were summarized to elucidate rule of TCM compatibility.

Objective To study the effects on berberine hydrochloride on the mitochondria membrane potential and free intracellular calcium of HaCaT cells, and elucidate the mechanism of action of berberine on keratinocytes. Methods Rhodamine-123 fluorescence (very sensitive to mitochondria membrane potential) and Fluo-3/AM fluorescence (suitabe to detect free intracellular calcium in single HaCaT cell) were measured by laser scanning confocal technique. Results Fluo-3/AM fluorescence intensity of HaCaT cells was persistently increased after treating with berberine at concentrations of 5 ? 10-5M, 2.5 ? 10-5M and 1.25 ? 10-5M, and significant differences were observed as compared with the PBS control. The intensity of rhodamine-123 fluorescence in HaCaT cells was decreased immediately when exposed to berberine, with significant difference from that of the PBS control. Conclusions It is suggested that berberine could increase free intracellular calcium and decrease mitochondria membrane potential of HaCaT cells, induce overload of intracellular calcium, influence energy metabolism, and then inhibit the proliferation of keratinocytes.

OBJECTIVETo investigate the clinical effect of bridging fixation with locking plate for the Seinsheimer type V subtrochanteric femoral fracture.

METHODSFrom March 2009 to September 2014,18 cases of Seinsheimer type V subtrochanteric femoral fracture were treated by open reduction and bridging fixation with locking plate through proximal and distal approach including 16 males and 2 females with an average age of 41 years old ranging from 22 to 67 years old. Among them, 12 cases caused by traffic accident, 5 cases by falling, 1 case by heavy aboving. All cases were fresh and closed fractures. Time between injury and operation was from 4 to 9 days with an average of 6.2 days. Of them, 11 cases were fixed with reverse LISS and the other 7 cases were fixed with anatomical locking plates of proximal femur.

RESULTSThe mean time of operation was 110 min (ranged from 90 to 155 min). The mean blood loss during operation was 425 ml (ranged from 350 to 650 ml) and 16 cases got blood transfusion which was meanly 300 ml. The mean hospital time was 14 days (ranged from 12 to 18 days). The mean duration of followed up was 11.8 months (ranged from 8 to 22 months). The mean time of bone union was 6.6 months (ranged from 5 to 8 months). There was not any complication such as infection, implant failure, hip varus, external rotation deformity of low limb or fat embolism. The Sanders hip scores were 53.22 ± 6.48, the result was excellent in 12 cases and good in 6 cases at the last follow-up.

CONCLUSIONUnder the principle of biological osteosynthesis, treatment of Seinsheimer type V subtrochanteric femoral fracture with bridging locking plate fixation has such advantages as high mechanism, less interference of blood supply, stable fixation and little complication. It is a safe and idea way for the treatment of the Seinsheimer type V subtrochanteric femoral fracture.

Objective To evaluate the short-term and long-term outcomes of patients with ST-segment elevation myocardial infarction (STEMI) compared with those with non-STEMI after percutaneous coronary intervention (PCI). Method The DESIRE Ⅱ (Drug-Eluting Stent Impact on Revascularization Ⅱ) was a single-center registered retrospective study of coronary revascularization in our institution between July 2003 and September 2009.Data of demographics, clinical features and revascularization record of STEMI and non-STEMI patients from the DESIRE Ⅱ trial were analyzed. The patients were followed up in OPD or by telephone after discharge. MACCE (major adverse cardiocerebral events) including death, neo-myocardial infarction, stroke and revascularization were recorded. The clinical outcomes of patients of two types were evaluated. Results There were 6005 patients studied with a median follow-up of 566 days. A total of 1009 STEMI and non-STEMI patients were analyzed. The patients with non-STEMI ( n = 206) had higher prevalence of hypertension and history of higher frequency of myocardial infarction as well as revascularization compared with patients with STEMI ( n = 803). The patients with non-STEMI had higher ratio of treatment for multivessel disease (43.7% vs. 34.4%, P = 0.039). There were no significant differences in in-hospital mortality and long-term outcomes (one year survival rate: 96% vs. 98%)between patients with STEMI and non-STEMI. The predictors of 1-year mortality were LVEF and blood creatine.Conclusions Despite different chnical features, patients with STEMI and non-STEMI after PCI had similar both short-term and long-term outcomes.

Human rhinoviruses (HRVs) are the causative pathogens in more than half of viral upper respiratory tract infections. Currently, no antiviral agents that are active against HRVs are available for clinical use. Because only higher primates are susceptible to HRVs, the screening of new drug is most commonly based on the cell line model. In this study, isolated rabbit airway smooth muscles (ASM) tissue model has been established, and the airway responsiveness with different treatment has been examined. Relative to control tissues, the maximal constrictor (Tmax) response to ACh increased significantly 150% in ASM inoculated with HRV, and relaxation to isoproterenol has been attenuated to 63%. And the abnormal responsiveness can be inhibited in presence of pretreatment with several new compounds which have been exhibited effective anti-HRV activity on cell lines. The results demonstrate that the established ASM model will be applied to screening the anti-HRVs drugs.
