The incompatibility of traditional Chinese medicines is related to the clinical medication safety, so has attracted wide attentions from the public. With the deepening of studies on the incompatibility of traditional Chinese medicines represented by 18 incompatible herbs, the incompatibility of theory traditional Chinese medicines has raised to new heights. From the origin of incompatibility theory of traditional Chinese medicines, relationship of herbs, harms of incompatible herbs and principle of prevention to toxic effects of specific incompatible medicines, the innovation and development of the traditional Chinese medicine incompatibility theory was explored. Structurally, the incompatibility of traditional Chinese medicines refers to the opposition of two herbs based on seven emotions and clinical experience. The combination of incompatible herbs may lead to human harms, especially latent harm and inefficacy of intervention medicines. The avoidance of the combination of incompatible herbs and the consideration of both symptoms and drug efficacy are the basic method to prevent adverse reactions. The recent studies have revealed five characteristics of incompatible herbs. Toxicity potentiation, toxication, efficacy reduction and inefficacy are the four manifestations of the incompatible relations. The material changes can reflect the effects of toxicity potentiation and toxication of opposite herbs. The accumulation of toxicity and metabolic changes are the basis for latent harms. The antagonistic effect of main efficacies and the coexistence of positive and negative effects are the distinctive part of the incompatibility. The connotation of incompatible herbs plays an important role in the innovation of the traditional Chinese medicine incompatibility theory.

The aim of the paper is to reveals the variations of Dendrobium officinale amino acids in different strains and parts for breeding excellent varieties, and providing scientific basis for the expanding of medicinal or edible parts. The contents of 17 amino acids in 11 strains of D. officinale were determined by hydrochloric acid hydrolysis method. The total amino acids content of leaves was from 6.76 to 7.97 g per 100 g, and the stems was from 1.61 to 2.44 g per 100 g. As the content of amino acids in leaves was significantly higher than that of stems, and the composition was close to the ideal protein standard proposed by FAO/WHO. The leaves of D. officinale had the good prospect for the development of functional foods. The 9 x 66 strain which with high yield and polysaccharide content had the highest amino acids content both in stems and leaves, indicated crossbreeding could improve the quality of varieties. Compared the amino acids content of D. officinale in two main harvest periods, the harvest time has a significant impact on amino acids content of D. officinale. This study demonstrates that the harvesting time of D. officinale stems is suitable for leaves as well, which is the period before bolssom.

The combination of Danggui and Honghua (GH) is a popular herb pair commonly used in clinic for the treatment of blood stasis syndrome in China. To evaluate the activating blood circulation and dissipating blood stasis effects of the combination of different proportions of Danggui and Honghua on acute blood stasis rats, and optimize the proportion of GH to have the best activating blood circulation and dissipating blood stasis effect. Acute blood stasis rat model was induced by subcutaneous injection of adrenaline and ice water bath. The blood stasis rats were administrated intragastrically with GH (1 : 0, 4 : 1, 2 : 1, 3 : 2, 1 : 1, 2 : 3, 1: 2, 1 : 4 and 0 : 1) extracts. The whole blood viscosity (WBV), plasma viscosity (PV), and high shear whole blood relative index (HSWBRI), low shear whole blood relative index (LSWBRI), and erythrocyte aggregation index (EAI) were tested to observe the effects of GH on hemorheology of blood stasis rats. And the maximum aggregation induced by adenosine diphosphate (ADP) was tested to observe the effect of GH on platelet aggregation index of blood stasis rats. In addition, the prothrombin time (PT), thrombin time (TT), activated partial thromboplastin time (APTT) and plasma fibrinogen (FIB) were tested to observe the effects of GH on blood coagulation function of blood stasis rats. Then principal component analysis and multi-attribute comprehensive index methods were both used to comprehensively evaluate the total activating blood circulation and dissipating blood stasis effects of GH. The results showed that the hemorheological indexes and coagulation parameters of model group both had significant differences with normal group. Compared with model group, GH (1 : 0, 4 : 1, 2: 1, 3 : 2, 1 : 1, 2 : 3, 1 : 2, 1 : 4 and 0 : 1) could improve all the blood hemorheology indexes and regulate part indexes of blood coagulation function and platelet aggregation in acute blood stasis rats. Based on principal component analysis and multi-attribute comprehensive index methods, GH 1 : 1 and GH 3 : 2 both had the best effect of blood circulation and dissipating blood stasis, and the effect of GH 1 : 1 was slightly better than GH 3 : 2. These results suggest that GH could obviously ameliorate the abnormality of hemorheology and blood coagulation function in acute blood stasis rats. The optimized proportion of GH was consistent with regulations of medicine usage that GH 1 : 1 had the highest frequency used in traditional Chinese formulae. It could provide scientific basis for more effective application of the compatibility between Danggui and Honghua in modern clinic medicine.

OBJECTIVETo evaluate the efficacy and safety of the combination therapy of tamsulosin and solifenacin for mild and moderate benign prostatic hyperplasia (BPH) with overactive bladder (OAB).

METHODSWe randomly divided 166 patients with BPH and concomitant OAB into a mild obstruction symptom group (n = 88) and a moderate obstruction symptom group (n =78), 48 of the former group treated with 0. 2 mg tamsulosin + 5 mg solifenacin and the other 40 with 0. 2 mg tamsulosin; 36 of the latter group treated with 0. 2 mg tamsulosin + 5 mg solifenacin and the other 42 with 0. 2 mg tamsulosin, all administered once daily for 12 weeks. We obtained the International Prostate Symptom Score (IPSS), urine storage period symptom score (USPSS), voiding symptom score (VSS), Qmax, residual urine volume, OAB symptom score (OABSS) and adverse reactions, and compared them among different

RESULTSAmong the patients with mild obstruction symptoms, the combination of tamsulosin and solifenacin achieved remark-groups. able improvement in IPSS, USPSS, Qmax and OABSS as compared with the baseline (P < 0.05), but made no significant difference in the residual urine volume (P > 0. 05) , while tamsulosin improved IPSS only (P < 0.05). The combination therapy exhibited an obvious superiority over tamsulosin alone in improving IPSS (9.7 micro 3.0 vs 15.8 micro 3.3), USPSS (8. 1 micro 1.7 vs 12.3 micro 3.1), Qmax ([18.6 micro 2.3] ml/s vs [14.2 micro 2.3] ml/s ), and OABSS (5.3micro 1.3 vs 9.7 micro 2.7) (P < 0.05), but there were no obvious differences in residual urine, urine routine test results and adverse events between the two therapies ( P > 0. 05). In those with moderate obstruction symptoms, the combination therapy significantly improved IPSS, VSS, Qmax and OABSS (P < 0.05) but not the residual urine (P > 0. 05) in comparison with the baseline. The tamsulosin therapy achieved obvious improvement in IPSS, VSS, Qmax, OABSS and residual urine. The combination therapy showed a better effect than tamsulosin only in OABSS (4. 8 +/-1.5 vs 6.5 +/-2.5, P < 0.05), but no significant differences from the latter in IPSS, Qmax, VSS, routine urine test results, and adverse

CONCLUSIONCombination therapy of tamsulosin and solifenacin is obviously safe and efficacious in the treatment (P > 0.05). events of both mild and moderate BPH with concomitant OAB, and it is superior to tamsulosin alone.

OBJECTIVETo evaluate the safety and therapeutic effect of high-dose daunorubicin-based (HD-DNR) chemotherapy in the treatment of acute leukemia (AL).

METHODSThe clinical data of 25 AL patients, including 14 cases for induction chemotherapy, 8 for consolidation chemotherapy and 3 for reinduction therapy, which were treated with HD- DNR (DNR dosage of 90 mg/m(2)× 3 d) between June 2010 and August 2012 in our hospital were retrospectively analyzed, the adverse reaction of chemotherapy, especially cardiac toxicity and therapeutic effect were evaluated.

RESULTSMost of the adverse reactions were mild, including cardiac toxicity, and no patient discontinued therapy because of HD-DNR related toxicities. Grade 3 or higher adverse reactions occurred only in the infection (56%) and diarrhea (12%). Withdrawal or dose reduction due to strong adverse reactions was not observed in all patients. Adverse reactions of infections (92%), lower ejection fraction(52.6%), diarrhea (48%), nausea (36%), vomiting (36%), dental ulcer (36%) and myocardial ischemia (32%) were relatively more common. The median time of neutrophil count reached to ≥ 0.5 × 10(9)/L and platelet ≥ 20 × 10(9)/L were both 21 days(ranged 9-31 and 9-38 days). Nine patients were complicated with infections before chemotherapy and 14 after chemotherapy, mainly occurred in gastrointestinal tract and respiratory system. Gastrointestinal, liver and kidney toxicity was slight. The cardiac ejection decreased in 10 cases, but only 1 reached grade 2 without clinical symptoms. Of the 14 AL patients for induction chemotherapy, 13 achieved hematological complete remission. Eight patients received HD-DNR as consolidation chemotherapy remained complete remission, while 3 refractory/relapsed patients remained non-remission.

CONCLUSIONThe adverse reaction of HD-DNR based chemotherapy for AL treatment was mild, no obvious cardiac adverse reaction occurred. The treatment dose of DNR at 90 mg/m(2) × 3 d can be safely and effectively used to treat acute leukemia.
