Objective To explore the factors related with prolonged anesthesia recovery (PAR) in patients with cerebral palsy after gener-al anesthesia. Methods 293 patients with cerebral palsy who received lower limbs orthopedics (LLO) under general anesthesia during July, 2009 to August, 2014 were retrospected and the factors related to PAR were analyzed. Results 37 patients (12.6%) suffered from PAR. There was significant difference in factors including body-weight, grade of physical status for anesthesia according to American Association of Anesthesiologists (ASA), the style to set a venous channel, blood loss, general anesthesia combined with epidural anesthesia (GAEA), in-tra-operative inhalation anesthetics, and serious adverse events (SAE) between patients with or without PAR, according to single factor anal-ysis with chi-square test. It was significant that the factors of ASA grade (B=1.490), SAE (B=2.159) and GAEA (B=-1.487) according to non-conditional logistic analysis. Conclusion PAR is related to several factors and GAEA combined with general anesthesia contributes to the recovery of patients with cerebral palsy.

A simple, precise, and rapid high-performance liquid chromatographic method was developed and validated for the simultaneous determination of vitexin-2-O-glucoside, vitexin-2-O-rhamnoside, rutin, vitexin, and hyperoside. The HPLC separation was performed using a Shim-pack VP-ODS C18 column (250 mm × 4.6 mm i.d. , 5 μm) with the isocratic mobile phase consisting of tetrahydrofuran/acetonitrile/0.05% phosphoric acid solution (20:3:77, v/v/v), and the flow rate was set at 1.0 mL/min. UV detection was carried out at a wavelength of 360 nm and the whole analysis took 25 min. The method was linear in the range of 4.12-206.00 μg/mL for vitexin-2-O-glucoside, 4.05-202.50 μg/mL for vitexin-2-O-rhamnoside, 1.64-82.00 μg/mL for rutin, 1.74-87.00 μg/mL for vitexin, and 1.41-70.60 μg/mL for hyperoside with the correlation coefficient for each analyte more than 0.998.The limit of detection (LOD) and limit of qnantitation (LOQ) were 0.6 and 2 ng for vitexin-2-O-glucoside, 0.6 and 2 ng for vitexin-2-O-rhamnoside, 0.3 and 1 ng for rutin, 1 and 3 ng for vitexin, and 0.5 and 2 ng for hyperoside, respectively. Lntra- and inter-day precision and accuracy (RSD) were less than 3%. The developed HPLC method was successfully applied to the analysis of five flavonoids in hawthorn leaves, hawthorn fruits, and the preparations containing hawthorn leaves or fruits.

Objective To observe the application of multimodal analgesia (MA) in lower extremity orthopedic surgery (LEOS) for patients with cerebral palsy (CP). Methods 100 CP patients following spasm undergoing LEOS under combined general anesthesia were randomly assigned into group C (n=50) and group M (n=50). In group M, the methods including a small dose of intravenous ketamine (0.25 mg/ kg) 15 minutes before skin incision, 0.25% ropivacaine hydrochloride in surgical area with infiltration anesthesia just before skin incision, and an intravenous infusion of sufentanil (0.05 μg/kg/h) combined with remifentanil (0.2 μg/kg/min) were performed. In group C, the methods mentioned above were not performed. The intravenous analgesia pump for single-use was prescribed for the patients in both groups. The postoperative analgesic effect (PAE) and side effects were observed. Results 4 dropped in group C. PAE in group M was significantly superior to that in group C (P<0.05), and the doctors as well as the caretakers for the patients were more satisfactory with the outcome (P<0.001). There was no significantly difference in the side effects between two groups (P>0.05). Conclusion MA could increase PAE in LEOS for CP patients following spasm and the safety was not influenced.

OBJECTIVETo investigate the absorption kinetics of atractylenolide I in intestines of rats and the influence of P-glycoprotein (P-gp) on the absorption.
METHODThe absorption kinetics was investigated using the method of in situ intestine absorption in rats and the samples were determined by HPLC.
RESULTAtractylenolide I is absorbed quite well at all segments of intestine in rats and no specific absorption was founded in different segment. When the concentration of perfusion solution was increased contrarily the absorption rate constant (Ka) kept at the same level. Compared Ka of three different concentration of perfusion solution with variance analysis method, Ka of atractylenolide I had no significant differences. But the Ka values were significently increased in the presence of P-gp inbibitor, verapamil or digoxin.
CONCLUSIONAtractylenolide I can be classified into high penetrating drug. Passive diffusion dominates the absorptive transport behivior of atractylenolide I. Atractylenolide I can be absorbed in the whole intestinal segments and there is not a preferntial absorption zone in the intestine. The absorption and secretion of atractylenolide I are mediated by the efflux transport system, P-gp.

2-methacryloyloxyethyl phosphorylcholine (MPC) polymer membranes are synthesized as biomaterials of the biomembrane structure. The MPC polymer membranes have excellent biocompatibility and blood compatibility, they can effectively reduce protein adsorption and denaturation and inhibit cell adhesion even when the polymer membranes are in contact with whole blood in the absence of any anticoagulants. So, the MPC polymer membranes are widely used in blood purification, artificial organs, membrane oxygenator, and other field of biomedicine. The paper mainly expounds the research advancement and the application prospect of MPC polymer membranes.

OBJECTIVETo study the protective effect of atractylenolide I on immunological liver injury induced by BCG and LPS.
METHODKunming mice were randomly divided into 6 groups: the normal group, the model group, positive control biphenyl group, the atractylenolide I high does group, the atractylenolide I middle dose group and the atractylenolide I low dose group (60, 120, 240 mg x kg(-1)), with 12 mice in each group. Immunological liver injury in mice was induced by BCG and LPS to compared liver index and spleen index and detect content of serum ALT, AST, MDA and GSH-px in serum and NO, iNOS, TNF-alpha in serum and liver homogenate. Liver pathological changes were observed by HE staining.
RESULTBoth of atractylenolide I and biphenyl remarkably decrease the increased live index and spleen index (P < 0.05), improve the histopathological changes in liver and pathological grades of liver tissues and relieve the inflammatory reaction induced by BCG and LPS. They showed a notable effect in improving MDA and GSH-px in serum.
CONCLUSIONAtractylenolide I can obviously protect immunological injury liver a dose-dependent manner within the range of test doses. Its mechanism may be related to release or over expression of inhibitory inflammatory medium such as NO, iNOS and TNF-alpha.
