Objective To observe the influence of Gastrodia data capsule on cerebral blood flow in the treatment of patients with hypertension.Methods A total of 69 patients with hypertension were divided into the treatment group(36 cases) and the control group(33 cases).The treatment group received treatment of Gastrodia clara capsule combined with antihypertensive drug,the control group received treatment of antihypertensive drug only.Two groups received TCD test before and 20 days after treatment,and the changes of blood flow of intracranial vessels before and after treatment were assessed.Results The total effective rate in treatment group was 97.2％,12 cases cured,15 cases of tangible effectiveness,8 cases of effectiveness,1 case of invalidity.The total effective rate in control group was 75.8％,7 cases cured,12 cases of tangible effectiveness,6 cases of effectiveness,8 case of invalidity,The difference of clinical efficacy between the two groups was statistically significant ( Z =2.240,P ＜ 0.05 ).The mean velocity of MCA,ACA,PCA,BA,VA of control group 20 days after treatment was not statistically different compared to those before treatment.The mean velocity of MCA,ACA,PCA,BA,VA of treatment group 20 days after treatment was lower than those before treatment(t =-2.65,-2.44,-3.92,-3.31,-4.68,all P＜0.05).Conclusion The treatment of Gastrodia elata capsule conbined with antihypertensive drug can significantly improve curative effect of patients with hypertension and improve the condition of cerebral blood flow.

A sensitive, rapid and specific liquid chromatographic-tandem mass spectrometric (LC-MS/MS) method for quantification of gabapentin in human plasma has been developed. After a single plasma protein precipitation with methanol, gabapentin and metformin (internal standard) were chromatographed on a Inertsil ODS-3 column (50 mm x 2.1 mm ID, 3 microm) with mobile phase consisting of methanol-0.2% formic acid aqueous solution (80:20, v/v) at a flow-rate of 0.2 mL x min(-1). Electrospray ionization (ESI) source was applied and operated in the positive ion mode. Multiple reaction monitoring (MRM) mode with the transitions of m/z 172 --> m/z 154 and m/z 130 --> m/z 71 were used to quantify gabapentin and metformin, respectively. The run time was 2.2 min. The linear calibration curve was obtained in the concentration range of 40.8-8.16x10(3) ng x mL(-1). The lower limit of quantification was 40.8 ng x mL(-1). The intra- and inter-day precision (RSD) was less than 12%, and the accuracy (RE) was within +/-6.4% calculated from quality control (QC) samples. The method was used to determine the concentration of gabapentin in human plasma after a single oral administration of 600 mg gabapentin capsule to 20 healthy male Chinese volunteers. The method was proved to be selective, sensitive, rapid and suitable for pharmacokinetic study of gabapentin in human plasma.

Objective To evaluate the correlation between serum uric acid with cognitive disorder after acute cere?bral infarction by prospective study. Methods Four hundred consecutively enrolled patients of acute cerebral infarction were divided into no cognitive impairment group and cognitive impairment group according to the assess of Montreal Cog?nitive Assessment (MoCA). Univariate analysises were conducted in the potential risk factors of cognitive impairment in?cluding age, sex, smoking, alcohol, hypertension, diabetes, dyslipidemia, level of education, infarction in key parts, atrial fibrillation, serum uric acid, blood homocysteine between two groups. The statistically significant indicators in univariate analysises were used as independent variables and the scores of MoCA were used as the dependent variable to conduct multiple linear regression analysis. The assessment on the risk of cognitive impairment after cerebral infarction were con?ducted according to serum uric acid, sex, age and TOAST classification further. Results Serum uric acid was indepen?dent risk factors of cognitive disorder after acute cerebral infarction. The risk of cognitive disorder after acute cerebral in?farction was significantly increased in patients with high level of serum uric acid than with normal level and the relative risk was 1.35,95%CI(1.098,1.660). Especially for the young, male or patients with cerebral infarction in classification of small artery occlusion, the risk increased further, and the relative risk was 1.513, 95%CI(1.092, 2.096)1.412, 95%CI (1.125, 1.771)and 1.464, 95%CI(1.128, 1.900)respectively. Conclusion Exaltation of Serum uric acid was indepen?dent risk factor of cognitive disorder after acute cerebral infarction. The risk of cognitive disorder after acute cerebral in?farction was significantly increased in patients with high level of serum uric acid than with normal level, and especially for the young, male and patients with cerebral infarction in classification of small artery occlusion, the risk increased fur?ther.

BACKGROUND: Recently biodegradable hydrogel has been extensively used to delivery anticancer drug and bioactive macromolecule. However, to protect the activity of the bioactive macromolecule, we need to obtain series of hydrogel which have milder hydrogelation conditions and shorter hydroglation time.OBJECTIVE: To prepare enantiomeric poly(L-Lactic acid) (PLLA)-poly(ethylene glycol (PEG)-PLLA/ poly(D-Lactic acid) (PDLA)-PEG-PDLA stereocomplex hydrogel which has shorter hydroglation time, to physically encapsulate a model drug-lysozyme and sustained release it from the hydrogel. METHODS: Triblock copolymers of PLLA-PEG-PLLA and PDLA-PEG-PDLA were synthesized by ring-opening polymerization of L(D)-lactide using PEG as the initiator and Sn(Oct)2 as the catalyst. The triblock copolymers were characterized by 1H nuclear magnetic resonance, FT-IR and X-Ray diffractometry. A hydrogel was prepared from an aqueous mixture of PLLA20-PEG227-PLLA20 and PDLA21-PEG227-PDLA21 (10 wt% concentration) at room temperature for 12 hours. X-Ray diffractometry test was used to research the gelation mechanism. The release profile of the lysozyme as a model drug from the hydrogel was tested. The morphology of the freeze-dried hydrogel was investigated by scanning electron microscope. The cytotoxicity of the hydrogel was evaluated by 3-(4,5-dimethylthiazol-2-yl-2,5-diphenyl tetrazolium bromide) assay.RESULTS AND CONCLUSION: Triblock copolymers of PLLA-PEG-PLLA and PDLA-PEG-PDLA were obtained. Both the PEG and PLA blocks in the copolymers could crystallize, but the crystallization of the PEG block was predominant. The stereocomplex formation between the PLLA and PDLA blocks within the hydrogel was confirmed by the X-Ray diffractometry analysis. The release profile of the lysozyme from the hydrogel exhibited a sustained-release pattern with a duration period of 7 days. The hydrogel exhibited a 3D interconnected porous structure with 50-100 μm pore size after being freeze-dried. The mouse fibroblast cell viability percentage was 99.3% after the cells contacted with the 100% extracted liquid for 72 hours.
