Objective The purpose of this study was to investigate the effects of cardiopulmonary bypass(CPB) on monocyte HLA DR expression and immune function Methods Sixteen ASA Ⅱ Ⅳ patients [mean age (38 5?5 1)yr,mean body weight (42 9?10 2kg)] of both sexes (male 7,female 9) with rheumatic value disease undergoing mitral value replacement (11 patients) and mitral value and aortic value replacement (5 patients) with moderate hypothermic CPB were enrolled in this study Another ten patients undergoing lung lobectomy were used as control group Patients suffering from infection, immuno deficiency or receiving corticosteroid or immunoregulatory drugs were excluded Premedication included intramusallar midazolam 0 1mg?kg -1 and morphine 0 1mg?kg -1 Anesthesia was induced with intravenous midazolam 0 15mg?kg -1 , fentanyl 8?g/kg and vecuronium 0 1mg?kg -1 and maintained with isoflurane inhalation (0 8%～1 2%) and intermittent boluses of fentanyl and vecuronium The total dose of fentanyl was (18 3?3 2)?g/kg in CPB group and (9 6?1 3)?g/kg in control group CPB time was (74 2?22 5) min and aortic clamping time (57 5?19 2) min Blood samples were taken from CVP line before and 5 min after induction of anesthesia, before and after CPB and on the 1st, 3rd and 5th postoperative day for determination monocyte count and percentage of HLA DR + monocytes Results The number of monocytes decreased at the end of surgery but greatly increased on the postoperative days The percentage of HLA DR + monocytes also decreased at the end of surgery and decreased further on the 1st postoperative day but started increasing on the 3rd postoperative day In two patients who developed infection the percentage of HLA DR + monoeytes was lower than the average percentage of HLA DR + monocytes of the other 14 CPB patients In control group the percentage of HLA DR + monocytes also decreased significantly after operation but there was no significant change in the number of monocytes However there was a significant difference in monoeyte HLA DR expression between the two groups Conclusions The changes in monocyte HLA DR expression and monocyte count may be induced by impaired immune response after CPB and dynamic monitoring of monocyte HLA DR expression may help to predict complication of infection after CPB

Objective To examine the expression of a- and ?-defensin genes in human peripheral leukocytes. Methods Fifty-one healthy blood donors were studied. Peripheral leukocytes were stimulated by lipopolysaccharide ( LPS) 100 ng?ml-1 ex vivo. The level of defensin mRNA expression in the leukocytes were assessed after being incubated with LPS for 0 (baseline), 1, 3, 6, 12, 24 h by semi-quantitative RT-PCR. Southern blot analysis and sequencing were used to confirm the identity of defensin gene transcripts. Results Expression of ?-defensin 1-3 mRNA was detected in all donors studied, but no ?-defensin mRNA expression was detected in peripheral leukocytes before LPS-stimulation. Expression of ?-defensin-1 gene was detected in the leukocytes after being incuaated with LPS for 3 h in 45 of 51 donors (88.2% ) and ?-defensin-2 mRNA expression was positive in 20 donors (39.2 % ), but no ?-defensin-3 mRNA expression was detected. The levels of ?-defensin-1 and-2 mRNA peaked at 6 h and started decreasing at 12 h. In contrast there was no significant change in ?-defensin 1-3 mRNA in peripheral leukocytes after LPS-stimulation. Conclusion In human peripheral leukocytes ?-defensin-1 and-2 genes are induced transiently by LPS-stimulation;whereas ?-defensin 1-3 genes are constitutive. The induced expression of ?-defensin-1 and-2 genes show inter-individual variability.

OBJECTIVE:To establish the quality standard of Liyan mixture. METHODS:TLC was conducted to identify the Scrophularia ningpoensis,Terminalia chebula and Glycyrrhiza uralensis;HPLC was conducted to determine the content of chloro-genic acid. The column was Agilent Eclipse Plus C18 with mobile phase of methanol-0.2% phosphoric acid (18:82,V/V) at flow rate of 1.0 ml/min,the detection wavelength was 327 nm,column temperature was 30 ℃ and the injection volume was 20 μl. RE-SULTS:TLC showed S. ningpoensis,T. chebula and G. uralensis had clear spots and good separation. There was no interference for negative control. The linear range of chlorogenic acid was 0.16-1.6 μg(r=0.999 9);RSDs of precision,stability and reproduc-ibility tests were lower than 1.0%,recovery was 96.9%-101.4%(RSD=1.17%,n=9). CONCLUSIONS:The method is simple and reproducible,and can be used for the quality control of Liyan mixture.

Objective To compare the effects of neutral posture training (NPT) and gas resistance training on balance and motor func-tion in stroke patients. Methods From June, 2014 to February, 2016, 44 hemiplegic patients were randomly divided into control group (n=22) and experimental group (n=22). The control group received conventional decubitus trunk muscle training and sitting gas resistance train-ing. The experimental group received NPT. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE), Fugl-Meyer Assessment-Lower Extremities (FMA-LE), and Berg Balance Scale (BBS) before and after training. Results There was no significant differ-ence in the scores of FMA-UE, FMA-LE and BBS between two groups (t<0.962, P>0.05). The scores significantly increased after training in both groups (t>12.248, P<0.001), and were higher in the experimental group than in the control group (t>1.972, P<0.05). Conclusion The NPT could improve the motor and balance function of stroke patients, rather than gas resistance training.

OBJECTIVE:To promote effective development of services in the intravenous drugs allocation centre and to bring the pharmacists'function into full play in the hospital pharmacy.METHODS:Information concerning services in the intravenous drugs allocation centre of our hospital and experiences from which was introduced,some problems and difficulties in the pharmacy services were analyzed.RESULTS&CONCLUSION:The centralized allocation and management of intra-venous drugs have ensured the safety and effectiveness of the clinical intravenous drug use and which have become the essential part of the pharmaceutical care with a core of rational drug use.

Conclusion The effectiveness of promotion of TCM appropriate technology packages from high to low is pains in neck, shoulder, waist and lower extremities package, chronic gastropathy package, gynecological diseases package, infantile diarrhea package, tumors package.

Objective To analyze the clinicopathological features of gastric stromal tumor with primary gastrointestinal carcinoma.Methods 469 cases of gastrointestinal stromal tumor (GIST) from January 2011 to December 2014 admitted to PLA General Hospital were retrospectively analyzed.Gastric stromal tumor patients with primary gastrointestinal carcinoma were screened.The concomitant gastrointestinal cancer site,stromal tumor size,mitotic activity,immunohistochemistry were also detected.Results The gastric stromal tumor with primary gastrointestinal carcinoma accounted for 14.7 ％ (69/469) of all the GIST,in which the small gastric stromal tumor accounted for 65.2 ％ (45/69) of the total and 9.59 ％ (45/469) of all the GIST.The diameter of all tumors was ＜ 5 cm,and the mitotic was ＜ 5/50 HPF.The positive rates of CD117,CD34,DOG-1 were 92.8 ％ (64/69),92.8 ％ (64/69),94.1％ (65/69).The Fletcher was classified as low-risk and extreme low-risk.Conclusions Gastric stromal tumor with primary gastrointestinal carcinoma has no specific clinical features and pathological immunohistochemical markers.Its malgnant degree is lower than GIST.Its prognosis is associated with primary gastrointestinal cancer staging.

Mitochondria DNA was isolated from darkgrown shoots of Xi Feng A according to the procedure reported previously. Mitochondria DNA was digested with EcoR1 completely, and ligated with pUC19 vector DNA which was digested with EcoR1. The ligated DNA was transformed into E. coli JM101. The transformants were selected on LB medium which containing ampicillin 50ug/ml. All of the bacterial clones were hybridized with 32P-labelled maize 26S rRNA gene, seven positive clones were obtained. The plasmid DNAs were isolated from the clones and digested with EcoR1 and southern transferred to NC paper. The membrance was hybridized with maize 26S rRNA probe. One clone which a shortest hybridization band (1.3kb) was named pXMT1.
