AIM:To develope a reversed-phase high performance liquid chromatographic method for determing chlorogenic acid and caffeic acid in Fanhuncao Granule(Senecio cannabifolius Less). METHODS: The operation was carried out on Eclipse XDB-C_(18) column with the mobile phase consisting of a mixture of acetonitrile-0.4% phosphoric acid(12(∶)88,V/V).The flow rate of 1.0 mL/min and UV detection wavelength at 327 nm were set to determine the contents of chlorogenic acid and caffieic acid. RESULTS: There was good linear relationship between the concentrations and the peak-areas of chlorogenic acid and caffeic acid.The two kinds of standard solutions were both stable in 16 h(RSD=1.55% for chlorogenic acid,1.11% for caffeic acid) The average recovery was 100.1% and 99.8% for chlorogenic acid and caffeic acid,repectively. CONCLUSION: The method is simple,sensitive,rapid and accurate,and can be used for the quality control of Fanhuncao Granule.

Objective:To evaluate the curative effect of mirror therapy combined with rehabilitation training in the treatment of stroke hemiplegic upper limb motor dysfunction. Methods:To choose 48 patients, were randomly divided into control group, 24 cases in each group to observe, are basic rehabilitation training, observation group joint mirror therapy, using FMA, ARAT, BMI, respectively, evaluation of patients with general motor function, upper limb motor function, daily life ability, numerical measurement of radial carpal extensor emg. Results:After the treatment, the control group, the observation group the FMA level, ARAT level, MBI level, EMG level was higher than that before treatment, the observation group than that in the control group, the observation group FMA, ARAT, MBI, the difference of EMG signals is higher than that of control group, with significant difference(t=14.14,t=4.55,t=5.84, t=9.14;P<0.05).Conclusion: mirror therapy combined with rehabilitation training is really helpful to upper extremity motor functional recovery of stroke patients with hemiplegia, is of positive significance to improve the living ability of the patients.

Double template molecularly imprinted polymer ( D_MIP) was prepared by emulsion polymerization method using the nonylphenol (NP), bisphenol A (BPA) as templates, α_methyl methacrylate(MAA) as functional monomer. Then using the D_MIP as solid phase extraction materials, a method based on double_molecularly imprinted solid phase extraction coupled with high performance liquid chromatographic fluorescence detection was developed for the determination of trace NP and BPA from environmental and food samples. The D_MIP was characterized by Fourier transform infrared spectroscopy ( FT_IR ) and adsorption experiments. The results showed that the saturated adsorption capacity of the D_MIP for NP and BPA was 73. 3 and 97. 5 mg/g, respectively, and the relative selectivity coefficient was 2. 2 and 1. 7, respectively. Moreover, the conditions affecting extraction efficiency, such as washing conditions and desorption conditions were optimized. Under the optimal conditions, there was a good linear correlation in the concentration range of 0. 01-2. 3 mg/L with correlation coefficients (R2) greater than 0. 998 for NP and BPA. The detection limits ( S/N=3) were 0. 001 and 0. 002 mg/L. The proposed method was applied to determine NP and BPA in river water, beer and crucian carp samples. The recoveries of NP and BPA were in the range of 86. 4%-99. 1%with the relative standard deviation less than 6 . 2%. This method has good selectivity and high sensitivity and shows good prospects for the application in the enrichment and separation of NP and BPA in real samples.

Objective To summarize the causes of abdominal pain in the early postoperative period after laparoscopic cholecystectomy(LC), so as to employ preventative measures. Methods The clinical data of 35 patients with early postoperative abdomial pain after LC were analyzed retrospectively and the literature was reviewed . Nine cases underwent reoperation, and conservative treatment was successfully performed in the other 26 cases. Results Traumatic factors were involved in 8 cases, including 6 cases of postoperative biliary fistula , and 2 cases with calculus retained in the trocar hole of the abdominal wall. 27 cases had no traumatic factor and included 2 cases of ascariasis of common bile duct, 5 cases with calculus of common bile duct, 1 case of acute pancreatitis, 17 cases of bile duct dysfunction, 1 case of duodenal ulcer and 1 case of stomach cancer. All were cured. Conclusions The key to decrease complications after LC is a complete examination before LC and pay attention to each aspect of perioperative management.

Objective To investigate inhibitory effect of Telmisartan on carotid arterial intima-media thickness in patients with essential hypertension. Methods 104 patients with mild or mid essential hypertension were randomly divided into three groups, which include telmisartan group( telmisartan 80 mg/d PO), ramipril group( ramipril 5 mg/d PO), and control group( other anti-hypertension agents). Blood pressure was monitored during treatment. Carotid arterial intima-media thickness(CIMT) were measured in all patients at beginning and patients who had the 12 months course. Results There were 91 patients who had the 12 months course,which include telmisartan group33 cases,ramipril group28 cases, and control 30 cases. The CIMT was significantly decreased in telmisartan group and ramipril group ( all P < 0. 05 ), and not changed in control while blood pressure fall effectively. In ramipril, group5 cases were ceased the course because of severe cough. Conclusion Both telmisartan and ramipril could decrease blood pressure and CIMT effectively, and there were less side effects in telmisartan group.

Objective To discuss the surgical treatment for huge hepatoblastoma in children,and the technique of hepatectomy without blockade of the blood supply to the remained liver lobes.Methods We reviewed 12 cases of huge hepatoblastorna who had been operated from July 2001 to January 2009 in our hospital.The mean age of the children was 3.2 years(range,11 months to 12 years).The diameter of the tumor was from 10 to 23 cm.3～7 cycles of chemotherapy was routinely administrated before operation.When the tumor reduced to a certain size that radical resection could be performed safely,regular hepatectomy was conducted.Hepatoblastoma resection without blocking the blood supply to the remained liver lobes was performed in every patient.Results The operations were successfully accomplished in all the 12 children.5 cases received right trihepatectomy (segment Ⅳ,Ⅴ～Ⅷ),4 cases received right hemihepatectomy(segment Ⅴ～Ⅷ),and the other 3 cases received Ⅳ,Ⅶ,Ⅷ segmentectomy,right Ⅴ,Ⅵ segmentectomy,and left hemihepatectomy respectively.The intraoperative hemodynamic parameters were stable,and there was no perioperative mortality.Postoperative chemotherapy wag routinely administrated.The follow-up period varied from 2 to 92 months.11 children survived and were disease free,among those 6 children have survived for more than 5 years.One child had brain and lung metastasis 5 months post operation,and died 7 months post operation. Conclusion Preoperative chemotherapy administrated to children with huge hepatoblastoma can reduce the tumor size and render tumor reseetable.Hepatoblastoma resection without blocking the blood supply to the remained liver lobes is a safe and feasible surgical technique.
