Abstract: Fifteen novel ligustrazine-tetrahydroisoquinoline derivatives were designed and synthesized according to the association principle of pharmaceutical chemistry. The structures were identified by IR, NMR and ESI-MS. The inhibitory activities of platelet aggregation induced by ADP and AA have been measured by Bron method. Preliminary pharmacological results showed that compounds 7g, 7h and 7n had potent inhibitory activity against platelet aggregation induced by AA, and the compound 7o showed significant inhibitory activity against platelet aggregation induced by ADP.

Objective To assess the efficacy and safety of dl-3-butylphthalide on the treatment of acute ischemic stroke. Methods A total of 197 patients who were in the period of 72 hours of first attack of ischemic stroke of internal carotid artery with NIHSS from 5 to 25 scores were enrolled in this multi-center, randomized, double-blind and aspirin-control study. Compound " Dan Shen" was used as a baseline therapy. Results Basical recovery plus significant improvement was seen in 74.7% of the patients in dl-3-butylphthalide group and 60.9% in aspirin group (CMH value 4.0,P=0.047);There was a significant improvement for dl-3-butylphthalide group regarding NIHSS total score, total score difference value and Barthel index on the day 11th and 21st after treatment compared with control group. The main adverse reaction of dl-3-butylphthalide was increased aminotransferase and mainly the slight increase of aspartate aminotransferase, by 4.34% and 0 respectively. Conclusion dl-3-butyiphthalide should be regarded as an effective and safe treatment for ischemic stroke and a treatment without severe side effects.

Traditional Chinese medicine (TCM) dispensing is the final step of TCM used for clinical treatment, the stability of TCM dispensing is the guarantee of good clinical effect. Establishment of effect-constituent equivalence for Chinese herbal pieces based on clinical efficacy, can not only guarantee the stability of TCM dispensing, but also relate to the precision of clinical effect. This study chose Coptidis Rhizoma as the model, established effect-constituent equivalence of Coptidis Rhizoma, based on the effect-constituent index already established by our research group, and taking into consideration of homogeneity of clinical dosage and compliance of decoction, the uniformity of dispensing for different specification of Coptidis Rhizoma decoction pieces was studied. This research model was then applied to guide the specification-optimization of Coptidis Rhizoma and its clinical dispensing. The result indicated, effective constituent equivalence could reflect the fluctuation of specification, dosage and decoction to the fluctuation of efficacy; Optimized Coptidis Rhizoma decoction pieces had the characteristic of high homogeneity as for clinical dispensing, good compliance as for decoction, and high effective constituent equivalence. In conclusion, effective constituent equivalence could improve relevance of methods of TCM dispensing control to clinical effect. Preparated Superior-standard Decoction Pieces based on effective constituent equivalence was featured by good quality and a good practice of adjustable dosage, which could promote the development of TCM decoction pieces toward precision medicine.

Fournier gangrene is a relatively rare clinical critical disease, and its clinical symptoms are not specific and easily unrecognized by some clinicians. It has the features of acute onset, quick development, severe illness, and often accompanied by infection shock which is seriously life-threatening. It is difficult in treatment with high medical costs and long length of hospitalization, which increases pain for patients and relatives and brings heavy economic and psychological burden on patients, society, and medical workers. By reviewing the literature home and abroad and combined with clinical practice, I summarize the researches on concept, epidemiology, clinical manifestation, diagnosis and treatment of Fournier gangrene, in order to provide reference for vast number of clinical workers.

OBJECTIVETo investigate the diagnosis and therapy of mediastinal enterogenous cysts in children.
METHODSClinical data of 17 cases with mediastinal enterogenous cysts within 19 years in our hospital were retrospectively analyzed.
RESULTSOne case was intramural esophageal cyst and 16 cases were enteric cysts, two among which were complicated with abdominal enteric duplications. Most cases presented with symptoms of respiratory distress. Twelve cases were complicated with vertebral anomalies. Ultrasound of 12 cases and magnetic resonance imaging of 4 cases were helpful in confirming the cystic nature of these lesions. Eight cases had technetium-99m pertechnetate scintigraphy of posterior mediastinum.
CONCLUSIONSMost patients present with symptoms of respiratory distress, complicated with vertebral anomalies. Ultrasonography and magnetic resonance imaging may be helpful in confirming the cystic nature of these lesions. Technetium-99m pertechnetate scintigraphy is the most effective method for differentiation of the disease from other mediastinal cysts.

To analyze the characteristics of serum sodium in decompensated cirrhosis and evaluate the prognostic ability of the model for end-stage liver disease (MELD) in Na-containing models. Patients diagnosed with decompensated cirrhosis at our hospital were enrolled for study between June 2005 and October 2010. Patients were classified among three groups, according to serum sodium concentration: less than 125 mmol/L, 125 to 135 mmol/L, and more than 135 mmol/L. Mortality rates among the three groups were compared by Kaplan-Meier survival analysis. In addition, the different serum sodium concentrations were analyzed for correlations between Child-Pugh score and complication incidence rates of portal hypertension. The area under the receiver operating characteristic (ROC) curve (AUC) was used to compare the predictive abilities of MELD, MELD-Na, and the integrated (i) MELD scores for 3-month, 6-month and 1-year mortalities. A total of 467 patients were analyzed, and 50.54% had hyponatremia ( less than 135 mmol/L). Sodium concentration was correlated with mortality, and Kaplan-Meier survival analysis indicated that mortality was significantly higher in each subgroup with lower sodium concentration (all, P = 0.000). Likewise, sodium concentration decreased in conjunction with increased severity of decompensation, as classified by Child-Pugh scoring (sodium: A more than B more than C; mortality: A less than B less than C). With the exception of digestive tract bleeding, complication incidence rates of hepatic encephalopathy, ascites, spontaneous bacterial peritonitis, and hepatorenal syndrome increased when sodium concentration decreased. For predicting 3-month mortality, the AUC scores of MELD were not significantly different from the MELD-Na and iMELD scores (P more than 0.05). For predicting 6-month and 1-year mortality, the AUC scores of MELD-Na and iMELD were significantly higher than those of MELD (P less than 0.05). Hyponatremia is correlated with mortality and complications in decompensated cirrhosis patients. Incorporation of Na into the MELD may enhance it's prognostic ability.

OBJECTIVETo identify enterovirus 71 (EV71) strains isolated from patients with hand, foot and mouth disease (HFMD) in Guangdong and Fujian provinces from 2000 to 2001 by using phylogenetic analysis.
METHODSAll 25 samples were first tested for enteric viruses by RT-PCR using enterovirus specific primers EV-1 and EV-2, and then were identified for EV71 by RT-PCR using EV71 specific primers 159S and 162A. The amplicons of 485bp segment (part of the VP1 gene) were cloned into pGEM-T and sequenced. A phylogenetic tree was constructed by comparison of the sequences with other 12 EV71 strains isolated from China, Japan, Hungary, and the United States including the prototype BrCr.
RESULTSThe positive rate of EV71 was about 20%. The sequence analysis showed that the new isolate (GZH2000) shared 94%-96% nucleotide identity with three strains isolated in 1998 and 2000, and 91% with a strain isolated in 1987 from Chinese mainland, but shared only 82%-84% homology with EV71 isolates studied abroad.
CONCLUSIONSEV71 is one of the important pathogens of HFMD in south China. The strains isolated from mainland were closely related with most isolates from Taiwan, but different from most EV71 strains reported abroad. The symptoms of EV71 infection in mainland were not as intensive as those described in Taiwan's outbreak.
