Results:The therapeutic efficacy was increased by the participation of clinical pharmacists in the therapy,the potential risk of the chemotherapy was avoided and the security of medication was assured. Conclusion:The participation of clinical pharmacists in therapeutic practice can improve the normalization of pharmacotherapy for ovarian cancer patients with cirrhosis,which also can provide ideas and methods for treating the similar patients.

Objective:To explore the Optimize concentrate process of loganin from Cornus officinalis by ultrafiltration-nanofiltration coupling technology. Methods:Based on single factor test, nanofiltration membrane pore size, transmembrane pressure difference and pH were selected as independent variables, and the rejection of loganin was used as dependent variables. Response surface methodology of Box-Behnken Design was applied to optimize the concentrate process of loganin from Cornus officinalis. Results:Ultrafiltration can remove polysaccharides and improve the filtrability of the solution. The optimum nanofiltration concentrate conditions were nanofiltration membrane pore size 400 Da, pH 6.7 and the transmembrane pressure difference was 1.20 MPa. The average cut-off rate of loganin was (91.9 ± 1.7)%, which was close to the theoretical cut-off rate of 93.6%.Conclusion:The loganin from Cornus officinalis has been concentrated efficiently by the combination of ultrafiltration and nanofiltration. The coupling technology is stable and feasible, whinc could avoid the transformation loss of heat-sensitive ingredients.

OBJECTIVETo observe the therapeutic efficacy of Dangfei Liganning Tablet (DLT) in the treatment of antipsychotics induced mild hepatic damage.

METHODSTotally 80 mental inpatients with antipsychotics induced mild liver injury were randomly assigned to two groups, the treatment group (40 cases) and the control group (40 cases). Patients in the treatment group took DLT, two tablets each time, three times per day, while those in the control group took Liver-protecting Tablet (LT), four tablets each time, three times per day. The treatment course was 4 weeks for all. Changes of glutamic-pyruvic transaminase (ALT) and glutamic-oxalacetic transaminase (AST) were observed before treatment, week 1, 2, and 4 after treatment. The therapeutic efficacy was compared between the two groups.

RESULTSCompared with the former time point, ALT and AST gradually decreased in the two groups at week 1, 2, and 4 (P <0. 05). The cured rate was 72. 5% and the total effective rate was 97. 5% in the treatment group. They were 62. 5% and 90. 0% respectively in the control group. There was no statistical difference in the two indices between the two group (P >0.05). No obvious adverse reaction occurred in the two groups.

CONCLUSIONDLT could treat antipsychotics induced mild hepatic damage in a safe and effective way.

Objective To summarize the main early complications after pancreatoduodenectomy and analysis of the probable causes.Methods The clinical data of 576 cases who underwent pancreatoduodenectomy(PD) in our department between Feb 1990 and May 2009 were analysed retrospectively.Results There were 92 early postoperative complications occurred in 85 patients(14.8%).Gastrointestinal dysfunction,pancreatic leakage,intra-abdominal infections and hemorrhage were the most of complications,and 7 cases died during perioperative period(mortality 1.22%),among which 3 died of multiple system organ failure,2 died of hemorrhagic shock and 2 died of toxic shock.Preoperative hypoproteinemia and hyperbilirubinemia complicated with a high incidence of postoperative complications on multivariate analysis.Conclusions Meticulous preoperative preparation,delicate intraoperative technigne and close postoperative observation are the key points to decrease early complications and improve the prognosis of the patients who undergo PD.

According to the characteristics of low cost, high performance, high integration and long battery life of wearable medical devices, the mainstream low-power microcontroller(MCU) series were compared, and came to the conclusion that the MCU series based on ARM Cortex-M0+ architecture were suitable for the development of wearable medical devices. In aspects of power consumption, operational performance, integrated peripherals and cost, the MCU series based on Cortex-M0+ architecture of primary semiconductor companies were compared, aimed at providing the guides of MCU selection for wearable medical devices.

AIM:To explore whether down-regulation of peroxisome proliferator-activated receptor γ coactivator (PGC)-1α induces podocyte apoptosis and its mechanism.METHODS:The podocytes were cultured under high glucose (HG) condition and the cell apoptosis was analyzed by flow cytometry.The methods of real-time PCR and Western blot were used to analyze the mRNA and protein expression of related molecules in the control, HG-treated or siRNA-treated podocytes.RESULTS:The expression PGC-1α at mRNA and protein levels was significantly decreased in HG-injured podocytes.Down-regulation of PGC-1α expression in vitro by siRNA resulted in podocyte apoptosis.The nuclear protein expression of nuclear factor of activated T-cells (NFAT) was significantly increased in HG injured podocytes, indicating the NFAT activation.Down-regulation of PGC-1α expression also decreased the nuclear protein expression of NFAT.Moreover, silencing of NFAT expression by siRNA significantly abolished PGC-1α deficiency-induced podocyte apoptosis.CONCLUSION: Down-regulation of PGC-1α induces podocyte apoptosis.NFAT mediates PGC-1α deficiency-induced podocyte apoptosis.

A total of 100 insomniacs were randomly divided into intervention and contrast groups (n=50 each).The contrast group took only alprazolam while the intervention group received both alprazolam and other comprehensive regimens,including acupuncture,psychotherapy and traditional Chinese medicine.One course of treatment lasted 10 days for both groups and 6 courses were offered.After comprehensive interventions,as compared with contrast group,the scores of Pittsburgh Sleep Quality Index (PSQI) and Athens Insomnia Scale (AIS) decreased obviously in intervention group (P ＜ 0.05).And the curative rate (46％) and the total efficacious rate (96％) of intervention group were higher than those of contrast group (P ＜ 0.05).

Immediate patency assessment of a completed microvascular anastomosis is considered an essential step in a microsurgical procedure. The most frequently used patency test is the milking patency test, which is too traumatic for use in clinical microsurgery. An atraumatic patency test remains to be devised. According to the principle of mechanics that rolling friction is smaller than sliding friction, we designed the so-called rolling patency test. The femoral arteries of Wistar rats were used in the experimental study to make a comparison between the two patency tests. The result showed that intact endothelial cells covered more than 90% of the inner wall of the artery in the rolling patency test, but less than 25% in the milking patency test. The study suggests that the rolling patency test is a reliable and atraumatic immediate patency test for use in clinical microsurgery.
