OBJECTIVE:To study the plerosis effect of sodium magnesium fructose diphosphate (FDPM) on hypoxia/reoxygenation (H/R) injury of myocardial cells and the possible mechanism. METHODS: The myocardial cells which had been primary cultured for 4 days were used to establish H/R injury model before being assigned to five groups: H/R, H/R+FDPM (4.8, 2.4, 1.2 mg?mL-1). Then set up normal control with normal cells. The activities of lactate dehydrogenase(LDH), creatine phosphokinase (CPK) and the intracellular level of free calcium ([Ca2+]i) were detected after being treated with corresponding drugs, and the ultrastructures of myocardial cells were observed under transmission electron microscope. RESULTS: As compared with H/R group, FDPM groups significantly decreased the activities of LDH and CPK and the level of [Ca2+]i (P

Objective:To study the effect of yemazhui on concentration of levofloxacin in rinse solution of mice tracheae. Methods:50 mice were randomly divided into blank group、anwhlor group、yemazhui large-dose group、yemazhui middle-dose group, yemazhui low-dose group, each group had 10 mice. After administration of liquor natrii chloridi isotonicus (NS) 30 ml/10kg, amchlor1.00g/kg、yemazhui large dose 64.45g (curde drug)/kg、yemazhui middle dose 32.73g (curde drug)/kg, yemazhui low dose16.36g(curde drug)/kg, mice were intraperitoneal injected levofloxaein at dosage of 0.07g/kg 2hours after administration. The concentration of levofloxacin in excretion of mice tracheae was detected by HPLC. Results:Comparion with blank group, concentration of levofloxacin in excretion of mice tracheae of yemazhui large-dose group、yemazhui middle-dose group、yemazhui low-dose group was 4.58 times、3.18 times、1.86 times the amout of that. Conclusion:Yemazhui can enhance concentration of lwvofloxacin in rinse solution of mice tracheae.

OBJECTIVE:To compare the pharmacokinetics and bioavailability between domestic(test)and imported(reference)citalopram hydrobromide tablets and to evaluate the bioequivalence of the two preparations.METHODS:A single dose of 40 mg test tablet or reference tablet of citalopram hydrobromide was administered by randomized crossover way in 20 healthy male volunteers and the plasma concentrations of the citalopram hydrobromide were determined by HPLC.The pharmacokinetic parameters were calculated with 3p97 pharmacokinetic program and the bioavailability was evaluated.RESULTS:The concentration-time curves of two preparations fitted two compartment mode1.The pharmacokinetic parameters of the test preparation versus the reference preparation were as follows,Cmax:(147.00?86.04)ng?mL-1 vs.(154.13?87.57)ng?mL-1;tmax:(4.55?1.35)h vs(4.75?1.65)h;AUC0～196:(6 590.69 ? 1 866.00)ng?h?mL-1 vs.(7 156.26?2 181.18)ng?h?mL-1;AUC0～∞:(7 767.56?2 193.92)ng?h?mL-1 vs.(8 433.45?2 631.88)ng?h?mL-1.The relative bioavailability of the test citalopram hydrobromide tablet was(92.10?18.68)%.CONCLUSION:The domestic and the reference citalopram hydrobromide tablet are bioequivalent.

OBJECTIVE: To compare the bioequivalence between two kinds of Simvastain Tablets.METHODS: A single dose of 40mg of domestic Simvastain Tablets(test preparation) and imported Simvastain Tablets(reference preparation) was administered by randomized crossover way in 20 healthy volunteers with plasma concentrations of simvastain determined by liquid chromatography mass spectrometry. The pharmacokinetic parameters were calculated with 3p97 pharmacokinetic program and the bioavailability was evaluated.RESULTS: The concentration-time curve of two preparations fitted one compartment model.The pharmacokinetic parameters of the test preparation vs.the reference preparation were as follows: Cmax:(13.23?4.41) ng?mL-1 vs.(12.68?4.43) ng?mL-1;tmax:(1.64?1.20) h vs.(1.54?1.28) h;AUC0～12:(47.48?22.96)vs.(44.49?18.47) ng?h?mL-1;AUC0～∞:(50.87?24.06) ng?h?mL-1 vs.(47.11?19.54) ng?h?mL-1.The relative bioavailability of the test simvastain tablets was(106.72?15.20)%.CONCLUSION: The results suggest that two preparations are bioequivalent.

We present a case of two-year old boy with solitary atypical adenomatous hyperplasia (AAH) in extralobar sequestration (ELS), which was misdiagnosed as diaphragmatic hernia before surgery. Review of AAH and pulmonary sequestration (PS) revealed that the present case is the youngest of solitary AAH and also the first report of solitary AAH arising in ELS without a primary lung cancer. In a sense, the present case firstly supports the hypothesis that ELS may be an underlying cancer predisposition syndrome, so aggressive surgical therapy should be recommended for ELS.

Objective To explore the clinical characteristics and the prognosis of benin convulsions as-sociated with mild gastroenteritis( BICE) in children. Methods To study clinical features of 248 children with BCIE,they followed up for 12 months,and their prognosis were observe. Results Age between 3 months and 3 years,twice or more seizures were occurred on 124 patients. 64 patients suffered the seizures more than 30 mi-nutes. Cranial CT/MRI showed no abnormality. Laboratory examinations were normal, including plasma glu-cose,serum electrolytes and cerebrospinal fluid. Followed up for 12 months,14 patients (5. 6%) suffered from recurrence of BICE,12 patients (4. 8%) suffered from simple febrile seizures,and 8 patients (3. 2%) devel-oped epilepsy. Conclusion The prognosis is good in majority of cases,but some cases may transform febrile seizure or epilepsy. It is more likely to transform epilepsy,when the children suffer from febrile seizure.

Objective:To discusse the clinical features of sarcomatoid hepatocellular carcinoma to improve the understanding of diagnosis and treatment for sarcomatoid hepatocellular carcinoma. Methods:Data including clinical features and follow-up from 8 pa-tients admitted in Tianjin Medical University Cancer Institute and Hospital from January 2009 to April 2014 were retrospectively ana-lyzed. Results: The average age of all patients was 56.6 years old, and the male-to-female ratio was 3:1. Preoperative CT or MRI showed specific characteristics but it was difficult to confirm diagnosis. Pathological and immunohistochemical examination revealed an expressed epithelial-like phenotype. All 8 patients had advanced local tumor invasion and high lymph node metastasis rates. These patients received surgery, and the median survival time was 10.8 months (3 months to 35 months). Conclusion:Diagnosis of sarcoma-toid hepatocellular carcinoma mainly depended on postoperative pathological examination. Immunohistochemistry was beneficial for sarcomatoid hepatocellular carcinoma diagnosis and differential diagnosis. Surgical treatment prolonged survival time, but the overall prognosis remained poor.

According to recent studies,cardiovascular disease,infection and malnutrition are the most common complications of maintenance hemodialysis (MHD),which also the main causes of death. Further studies illustrate that dialysis patients with micro-inflammatory state,which relate to patient uremia and hemodialysis,further more,closely related to the existing micro-inflammatory response to the above complications. Accordingly,to explore the mechanism in MHD patients with micro-inflammatory response,and to search for the effective micro-inflammation treatment,in addition,to enhance the quality of life of patients with MHD and survival rate has become a hot spot in recent years.

ObjectiveTo analyze the potential risk factors for relapse and development of epilepsy in patients with benign in-fantile convulsions associated with mild gastroenteritis (BICE).MethodsA total of 264 cases of BICE were recruited. Accord-ing to the frequency of convulsions, the patients were divided into single group (n=134, convulsion once), and multiple group (n=130, convulsions≥2 times). According to convulsion duration, the patients were divided into short-term group (n=186, con-vulsions duration <5 minutes) , and long-term group (n=78, convulsion duration≥5 minutes). The clinical data obtained during hospitalization and follow-up were analyzed.ResultsIn multiple group, 9.23% were relapsed and 6.15% developed epilepsy. In single group, 2.99% were relapsed and 0.75% developed epilepsy. There were signiifcantly different in the rate of relapses and development of epilepsy between two groups (P<0.05). In the long-term group, 12.82% were relapsed and 8.97% developed epi-lepsy. In the short-term group, 3.23% were relapsed and 1.08% developed epilepsy. There were signiifcantly different in the rate of relapses and development of epilepsy between the two groups (P<0.05).ConclusionsThere are the risks of relapse and development of epilepsy in BICE patients. Convulsions≥ 2 times and≥5 minutes may be the risk factors of relapse and devel-opment of epilepsy.
