OBJECTIVE: To investigate the absorbability of 8 kinds of disposable filter membranes for infusion apparatus to 10 injectable drugs, thus to provide information for clinical medication. METHODS: Each drug was separately dissolved in 250 mL 5% dextrose solution. Samples of drug solutions were collected before and after being filtered by the membranes. These samples were analyzed by HPLC-MS/MS methods. RESULTS: The 8 kinds of membranes had different adsorbabilities to the 10 injectable drugs. CN-CA membrane (CN-CA) and CN-CA Enhance membrane (CN-CA-E) adsorbed more drugs than other membranes (P<0.05). The average adsorption of PES membrane, NL-B membrane and ION membrane to the 10 drugs were lower than 1%. PP membrane and NL membrane to the 10 drugs were lower than 1.5%. CONCLUSION: PES membrane, ION membrane and NL-B membrane have lower adsorbabilityies than other membranes, thus may have little influence on medical treatment. They may be suitable for clinical application. Copyright 2012 by the Chinese Pharmaceutical Association.

Objective To explore the relationship between phosphatidylinositol 3 kinase (PI3K)/protein kinase B (Akt)/mammals target protein rapamycin (mTOR) signal transduction pathway and Barrett esophagus genesis.Methods A total of 140 rats were divided into sham operated group (n=10),iron group (n =10),esophageal duodenal side anastomosis group (n =30),esophageal duodenal side anastomosis plus iron group (n-30),esophageal gastric duodenal side anastomosis group (n=30) and esophageal gastric duodenal anastomosis plus iron group (n=30).In the end,10 normal esophagus tissue specimens,62 reflux esophagitis tissue specimens and 34 Barrett's esophagus tissue specimens were obtained.The expression levels of epidermal growth factor receptor (EGFR),Akt,phospho Akt (p-Akt),phospho-mTOR (p-mTOR) protein were detected by immunohistochemistry.Single factor analysis of variance,SNK between two groups and nonparametric correlation analysis were performed for statistical analysis.Results The protein expression levels of EGFR,Akt,p-Akt,p-mTOR in Barret(s esophagus tissues were higher than those in reflux esophagitis tissues and normal esophagus tissues (EGFR 0.1799±0.0367 vs 0.0438±0.0025 and 0.0277±0.0069,q=6.79,4.13; Akt 0.1874±0.0250 vs 0.0986±0.0093 and 0.0383±0.0048,q=6.51,3.56; p-Akt 0.1418±0.0130 vs 0.0592±0.0027 and 0.0281 ±0.0017,q=7.68,3.99; p-mTOR 0.1591±0.0275 vs 0.0674 ±0.0059 and 0.0112±0.0017,q=5.62,4.11; all P＜0.05).The protein expression levels of EGFR,Akt,p-Akt,and p-mTORin reflux esophagitis tissues were higher than those in normal esophagus tissues(q=4.67,4.29,4.27,4.03; all P＜0.05).Conclusion PI3K/Akt/mTOR signal transduction pathway were activated in reflux esophagitis and Barrett's esophagus,which provided theoretical basis for clinical multi-target treatment for diseases.

Objective To observe the clinical effect of continuous intravenous pumping of octreotide in the treatment of intestinal endotoxemia.Methods Eighty patients with intestinal obstruction and non-surgical treatment were divided into group Ⅰ with 34 cases who received conventional-treatment and group Ⅱ with 46 cases who received conventional-treatment combined with octreotide 24 h continuous intravenous pumping.White blood cell count ( WBC ),diamine oxidase (DAO),D-lactic acid (D-LA) and endotoxin were detected before treatment and at 24 h,48 h,4 d after treatment.Results The content of WBC,DAO,D-LA and endotoxin in two groups all reached peak at 48 h after treatment.The difference of the content of WBC,DAO,D-LA and endotoxin between two groups had no statistical significance at 24 h after treatment (P ＞ 0.05).The content of WBC,DAO,D-LA and endotoxin of group Ⅱ at 48 h and 4 d after treatment were lower than those of group Ⅰ.And the difference at 48 h after treatment had statistical significance[(18.40 ±0.10)× 109/L vs.(20.60 ± 2.36) × 109/L,(6.12 ± 1.02) kU/L vs.(8.02 ± 1.54) kU/L,(2.14 ±0.21) mg/L vs.(3.34 ± 0.04) mg/L,(1.65 ±0.16) kEU/L w.(2.23 ±0.36) kEU/L] (P ＜ 0.01).While the difference at 4 d after treatment had no statistical significance(P＞ 0.05 ).Body temperature at 48 h after treatment,gastrointestinal decompression capacity,anus exhaust time of group Ⅱ were (37.60 + 3.01 )℃,(320.00 ± 76.14) ml/d,(54.00 ± 0.94) h respectively,and they all were superior to those of group Ⅰ[(38.50 ± 2.21 ) ℃,(500.00 ± 80.32) ml/d,(68.00 ± 1.02) h] (P ＜0.01).Conclusions Continuous intravenous pumping of octreotide can effectively protect the intestinal mucosal barrier function,improve intestinal permeability,reduce the trmslocation of intestinal flora,inhibit the incidence and development of enterogenous endotoxemia.And it provides new evidence to support the clinioal application of octreotide in patients with intestinal endotoxemia.

Objective To investigate the correlation of clinical stage and treatment plan with prognosis in incidental prostatic carcinoma.Methods From 2004 to 2010,a total of 1076 patients diagnosed as BPH underwent transurethral plasma kinetic enucleation of prostate (TUPKEP) in our hospital,and their clinical data were respectively analyzed.Among them,42 cases were found to have incidental prostatic carcinoma.The correlation of clinical stage and treatment plan with prognosis in incidental prostatic carcinoma were observed.Results Among 1076 BPH patients undergoing TUPKEP operation,42 cases (3.9％) aged 56-88 years were found to have incidental prostatic carcinoma,which all displayed as prostatic adenocarcinoma including 18 cases at T1 a stage and 24 cases at T1b stage.10 cases received endocrinal therapy,14 cases received bilateral orchiectomy,14 cases underwent radical prostectomy and 4 cases were treated with watchful waiting.Patients were followed up for 24 to 96 months.The survival rates were 100.0％ and the rates of progression were 0.0％,20.0％,0.0％ in T1 a patients received watchful waiting,androgen-deprivation therapy and radical prostectomy,respectively.Total survival rate was 100.0％ and total rate of progression was 11.1％ in T1a patients.The survival rates were 71.4％,100.0％ and the rates of progression were 42.9％,0.0％ in T1 b patients received androgen-deprivation therapy and radical prostectomy,respectively.Total survival rate was 83.3 ％ and total rate of progression was 25.0 ％ in T1 b patients.Compared with T1 b patients,the total survival rate was higher (x2=18.19,P＜0.01) and the rate of progression was lower in T1 a patients (x2 =6.52,P＜0.05).Conclusions The survival rate in T1 a patients accepted androgen-deprivation therapy is similar to that in T1 a patients with watchful waiting.Compared with T1a patients,the survival rate is lower but the rate of progression is higher in T1 b patients received active androgen-deprivation therapy.The survival rate is higher in T1 b patients treated with radical prostectomy than in those received other treatments.Watchful waiting is acceptable for T1 a patients.T1 b patients should be treated with radical prostectomy for a better effect.

Objective To observe the results of melatonin combined with alprostadil in the treatment of patients with acute pancreatitis.Methods Seventy patients with acute pancreatitis were included in the study,14 patients died after conventional treatment were set to group Ⅰ ,28 patients cured after conventional treatment were set to group Ⅱ and 28 cases cured after melatonin combined with alprostadil and conventional treatment were set to group Ⅲ.White blood cell count,blood gas analysis,serum amylase,endotoxin and malondialdehyde (MDA) content was detected at 6 h,48 h and 4 d.Results White blood cell count,serum amylase,endotoxin,MDA content at 6 h,48 h and 4 d in group Ⅰ were higher than those in group Ⅱ ,Ⅲ (P＜0.05).Endotoxin levels reached a maximum in the 4 d [(273.5 ± 20.4) pg/L],and MDA content reached a maximum in the 4 d [(5.12 ± 0.87) μmol/L].White blood cell count,partial pressure of carbon dioxide in artery (PaCO2),serum amylase,endotoxin and MDA content at 48 h,4 d in group Ⅲ were lower than those in group Ⅰ,Ⅱ (P <0.05).Conclusions Melatonin combined with alprostadil not only shows antioxidant,anti-inflammatory,anti-apoptotic effect but also improves the pancreas,lung,small intestine microcirculation,protects the cell membrane and the lysosomal membrane,and prevents effectively the pancreatic digestive enzymes release; also it inhibits intestinal bacterial translocation,reduces the generation of gut-derived endotoxin and pro-inflammatory cytokine release.It can reduce effectively the systemic inflammatory response in acute pancreatitis.

AIM　To quatitatively disclose the relationship between activity and structure of a new class of COX-II inhibitors containing dialkylphenyl-linked heterocyclic moieties. METHODS AND RESULTS Seventeen COX-II inhibitors from literature as a training set were investigated with the aim of developing a 3D-QSAR model using comparative molecular field analysis (CoMFA). To reveal the pharmacophoric pattern, several modes of superimposition were explored. The significant model shows a higher ability to explain and predict the activity of COX-II inhibitors, with the cross-validation RCV2=0.718, non cross-validation R2=0.992, F=260.624, and SEE (standard error of estimate)=0.072. Three compounds were selected as a predicting set, the low deviations of calculated values from the measured ones suggesting a powerful predictive ability of the model. CONCLUSION　The 3D-QSAR explains the dependence of COX-2 inhibition upon the structures of the compounds. Some structure information for design of new COX-II inhibitors with higher activity has been given.

Objective　To investigate the dynamic changes of psychological states and the results of delivery in pregnant women,simultaneously,study the effective way to reduce the rate of cesarean section.Methods　Through applying the self-compiled test paper,the self-evaluating state table(SCL-90)and the table of overall feeling of happiness,we assessed the psychological states of 89 pregnant women.The results were recorded at 35 and 38 weeks of gestation and 72 hours postpartum.Results　48 delivered vaginally(53.93%).4 were managed by cesarean section(46.07%),including 12 non-indicated cesarean section(29.27%).The mark of anxiety,terror and depression factors increased in the group of non-indicated cesarean section before and after dilivery compared with the group of vaginal delivery and indicated cesarean section.There was remarkable difference(P＜0.01).The value of overall feeling of happiness in the group of non-indicated cesarean section was less than that in the group of vaginal delivery.The difference was extremely significant(P＜0.001).The rdevant analysis showed that the feeling of happiness,the desire of labor and educational level were related negatively to the level of symptom during pregnancy(P＜0.01).The mode of delivery was related positively to the psychological state of pregnant women(P＜0.01).Conclusion　Non-indicated cesarean section is mainly interrelated to anxiety,terror and depression that proceed gradually during pregnancy and delivery.So it is suggested that the aimed psychological education be beneficial to decrease the rate of cesarean section.
