The pharmacological characteristics of recipes are multi-components, multi-ways, multi-links, and multi-targets, on which the efficacy substances in recipes are worth of studying. To explore the essential substances of Chinese herbs in recipe is one of the key points for modernization of Chinese materia medica. The pharmacological effects and bioactivities inside the target tissue of lesion body are still not clear, even though there are some progress in herb serum pharmacology, recipe pharmacokinetics, and pharmacodynamics. The main effective components of recipe to pancreas in acute pancreatitis models by ig or enema were investigated by HPLC-MS method so as to establish a new hypothesis (tissue pharmacology of recipe): i.e. guided hy fundamental theory of traditional Chinese medicine to study the effect and the mechanism of recipe's essential substances on target tissues with pharmacological methods; to establish the experimental method for searching the foundation, the principle, and the direct substances of recipes which act on target tissues; to form more effective formula if possible, and to explore in a new researching field for the recipes of Chinese materia medica.

With the increasing number of complex and difficult thyroid cancer patients, the traditional medical model is difficult to solve the problem of diagnosis and treatment of patients optimally. In recent years, multidisciplinary team (MDT) model is applied clinically. For complex and difficult thyroid cancer diseases, the model can play a multidisciplinary advantage and provide more personalized and accurate diagnosis and treatment scheme for patients. The diagnosis and treatment of complex and difficult thyroid cancer involve thyroid surgery, otolaryngology, thoracic surgery, anesthesiology, endocrinology, nuclear medicine, radiotherapy, oncology, ultrasound, imaging, pathology and other disciplines. Based on the important role of MDT in diagnosis, treatment, nursing, postoperative management and clinical research of thyroid cancer, as well as the challenges and difficulties faced in implementation of MDT, the status and progress of multi-disciplinary comprehensive diagnosis and treatment of thyroid cancer will be systematically elaborated in the paper.

Objective To investigate the effectiveness and methodology of percutaneous transluminal septal myocardial ablation (PTSMA). for hypertrophic obstructive cardiomyopathy (HOCM). Methods PTSMA with Sigwart's Method were performed in 57 patients with symptomatic HOCM from September 1999 to January 2005. Improvements were made about pressure monitoring, echocardiography guiding, the ablation procedure and the evaluation criteria of the operation. Results About 0.6-9.0 mL of absolute alcohol were consumed during PTSMA in each patient with 1-5 target septal branchs ablated per case. The resting and provoked left ventricular outflow tract pressure gradient monitored by catheter was reduced over 50% compared with preoperation level in all 57 cases. Two out of four cases with ECT exam had septal myocardial radioactive absence. During the follow-up of 2 weeks to 5 years, the clinical symptoms such as syncope, diziness, angina, palpitation and dyspnea, disappeared or were relieved in 54 cases compared with preoperation status. Two cases regained the above symptoms not long after the operation. One patient showed improvement in clinical symptoms and echocardiographic examination in 6 monthes, but she died of dilated congestive cardiomyopathy at 18 monthes after PTSMA. Follow-up echocardiographic examination was completed in 43 cases at 6 monthes and in 34 cases at 12 monthes after PTSMA. Further improvement was shown on UCG compared with 2 weeks after the operation. Some patients had transient or nonsustained ventricular tachycardia and atrioventricular block. Anteroseptal myocardial infarction was observed in 4 patients and 1 of them was accompanied by inferior myocardial infarction. Conclusion Percutaneous transluminal septal myocardial ablation for hypertrophic obstructive cardiomyopathy is safe and effective. Improvements have to be made for more satisfactory results of PTSMA.

OBJECTIVETo investigate the incidence of depression and its etiological factors in patients with cryptorchidism 6-16 years after surgical treatment.
METHODSUsing Self-Rating Depression Scale and Correlation Factor Questionnaire, we investigated the incidence of depression symptoms among 70 patients with cryptorchidism 6-16 years after surgical treatment and another 70 healthy males as controls, and analyzed the related factors of depression symptoms.
RESULTSThe incidence rate of depression symptoms was 50% in the cryptorchidism patients postoperatively, extremely significantly higher than 4.3% in the control group (χ2 = 23.5, P <0.01). Multiple stepwise regression analysis showed that the main risk factors of depression symptoms were worries about natural fertility (F = 15.8992, P <0.01), dissatisfaction with scrotal appearance (F = 4.6003, P <0.05), and the status of being married (F = 4.1002, P <0.05).
CONCLUSIONSymptoms of depression often occur in cryptorchidism patients after operation, and the major etiological factors are infertility, dissatisfaction with scrotal appearance, and the status of being married.

OBJECTIVETo observe the effect of Hydroxy Safflower Yellow A (HSYA) on the expression of osteogenic markers, such as alkaline phosphatase, Cbf(alpha)l and type I collagen, and explore the mechanism of HSYA in the prevention and treatment of glucocorticoid-induced ischemic necrosis of femoral head.
METHODSFifteen healthy and adult New Zealand white rabbits were collected and weighted 0.9 to 1.3 kg. The rabbits were injected abdominally with anesthetic drugs, then received marrow cavity puncture of tibia and anterior superior iliac spine to get bone marrow blood. Rabbits bone marrow mesenchymal stem cells (BMSCs) were separated from the bone marrow blood, cultured in vitro and passaged. The 3rd generation of BMSCs which had good growth condition were randomly divided into blank group, model group and HSYA groups with different doses. The BMSCs in model group were treated with high dose of dexamethasone to induce adipogenic differentiation of cells cultured in vitro, and inhibit osteogenic differentiation. The BMSCs in HSYA groups received high dose of dexamethasone and different concentrations of HSYA simultaneously. The blank group received not any special handling. After a week,the expressions of alkaline phosphatase, Cbf(alpha)l and type I collagen mRNA were detected.
RESULTSThe alkaline phosphatase activity was significantly decreased in BMSCs of the model group as compared with the blank group (P < 0.01), and the expression of Cbf(alpha)l and type I collagen mRNA were also decreased significantly (P<0.01). The alkaline phosphatase activity was significantly increased in BMSCs of each HSYA group as compared with the model group (P < 0.05 or P < 0.01), and the expression of Cbf(alpha)l and type I collagen mRNA were also increased significantly (P < 0.05 or P < 0.01).
CONCLUSIONThe mechanism of HSYA may be related to the effect of antagonism to the reduced osteogenic differentiation induced by glucocorticoid.

Objective: To explore the effects of ranitidine on pharmacokinetics of rhein in rats after oral administration of Dachengqi Decoction (DCQD), a compound traditional Chinese herbal medicine. Methods: Twelve male Sprague-Dawley rats were divided into DCQD group and DCQD plus ranitidine group, and were orally administered with DCQD at a dose of 10 g/kg or DCQD (10 g/kg) combined with ranitidine (150 mg/kg), respectively. Blood samples were gathered after a series of time intervals. Metabolism of rhein was determined with a reversed-phase high-performance liquid chromatography with internal standard of 1, 8-dihydroxyanthraquinone and the data were analyzed with DAS 2.1 program. The pharmacokinetic parameters were compared between the two groups. Results: The pharmacokinetic parameters of rhein in the DCQD group, including peak concentration (C(max)), area under the plasma concentration-time curve (AUC), distribution phase half-life (t(1/2alpha)), elimination rate constant (K(10)) and central to peripheral transfer rate constant (K(12)), were significantly different to those in the DCQD plus ranitidine group (P<0.05, P<0.01). There were no significant differences in the other parameters between the two groups. Conclusion: Ranitidine can influence the pharmacokinetics of rhein in rats after oral administration of DCQD.

Objective To observe the effects of hydrocortisone on the rate of return of spontaneous circulation(ROSC)and the outcome of patients with cardiac arrest(CA)and cardiopulmonary resuscitation(CPR). Methods A cohort study was conducted,78 non-traumatic patients with CA were divided into hydrocortisone group (31 cases)and control group(47 cases). Conventional treatments were given in the two groups after admission,and additionally intravenous 100 mg hydrocortisone was given to the hydrocortisone group during resuscitation. The ROSC rate and prognosis were compared between the two groups. Multivariate logistic regression analysis was used to predict the impact factor of ROSC. Results The ROSC rate and 24-hour survival rate in the hydrocortisone group were significantly higher than those of the control group(ROSC rate:58.1% vs. 40.4%,24-hour survival rate:48.4%vs. 36.2%,both P<0.05). There were no significant differences between the hydrocortisone and the control groups in duration of CPR〔minute:17.1(6-45)vs. 15.8(7-48)〕,acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ)score in survivors(37.2±8.2 vs. 36.1±8.2),the survival rate(12.9% vs. 12.8%)and hospital discharge rate(6.4%vs. 6.4%)in 7 days. Hydrocortisone〔odds ratio(OR)=3.12,95%confidence interval(95%CI)-1.18-8.29, P=0.017〕and witness(OR=4.24, 95%CI -1.87-12.43,P=0.008) were independent predictors for an increased ROSC rate after multiple logistic regression analysis. Conclusion Giving hydrocortisone during resuscitation may increase ROSC rate in CA patients.
