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.

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.

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.

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.

This study was aimed to probe into the mechanism of moxibustion in the treatment of Alzheimer’s disease (AD). A total of 40 male 15-month-old SD rats were randomly divided into the normal group, model group, moxibustion group and sham-operation group. Stereotactic injection of agglutinated Aβ25-35 into rat’s bilateral hippocampus was used to prepare AD models. Equal amount of normal saline was injected to rat’s bilateral hippocampus in the sham-operation group. Model rats were treated by moxibustion at the distance of 2-3 cm above points of‘BL23-Shenshu’, ‘ST36-Zusanli’ and ‘GV20-Baihui’. No intervention was given to rats in the normal group. The learning and memory ability was detected by Morris water maze test. Changes on expressions of Bcl-2, Bax and Caspase-3 of hippocampus zone were detected by immunohistochemical method. The results showed that in the model group, the average escape latency of five days and the last three days were significantly lengthened. And the times across the platform position were significantly reduced. Compared with the normal group and the sham-operation group, expressions of Bax and Caspase-3 in the hippocampus were significantly increased, and the expression of Bcl-2 was obviously decreased (P < 0.01). In the moxibustion group, the average escape latency of five days and the last three days were shortened obviously, and the times across the platform position were significantly increased. Compared with the model group, expressions of Bax and Caspase-3 were significantly reduced, and the expression of Bcl-2 was significantly increased (P < 0.01). It was concluded that the action mechanism of AD treatment with moxibustion may be through the reducing of proapoptotic protein Bax and Caspase-3 releasing, promoting the releasing of anti-apoptotic protein Bcl-2, so as to improve the learning and memory impairment caused by Aβ.

Objective To observe the effects of moxibustion on learning and memory ability and nerve cell ultrastructure in CA1 region of hippocampus of rats with Alzheimer's disease (AD);To discuss its mechanism of action to AD.Methods A total of 40 male SD mice was randomly divided into normal group, model group, moxibustion group and sham-operation group. Stereotactic injection agglutinated Aβ25-35 into bilateral hippocampus of rats in model group and moxibustion group to prepare AD models. Rats in moxibustion group were treated by moxibustion at the points which were located above 2-3 cm away from Shenshu, Zusanli and Baihui. Rats in normal group received no treatment. The learning and memory ability was detected by Morris water maze test. Morphological changes of rat nerve cell ultra structure in hippocampal CA1 region were observed by transmission electron microscope.Results In model group, the average escape latency of five days and the last three days was significantly lengthened, and the times across the platform position significantly decreased. Transmission electron microscope indicated nerve cell structures were damaged and displayed unclearly;mitochondrion swelled, even mitochondrial crista was abnormal and deformed, endoplasmic reticulum of inter organelle expanded and the deposition of lipofuscin increased. After the treatment by moxibustion, the average escape latency of five days and the last three days was shortened obviously, and the times across the platform position significantly increased. In moxibustion group, the edema of nerve cells significantly decreased;dilation of endoplasmic reticulum and mitochondria swelling significantly improved;golgi bodies, mitochondria and ribosomes obviously increased in comparison with the model group. Conclusion Moxibustion can improve the learning and memory impairment caused by Aβ by promoting repairing of nerve cells in brain.

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.
