Objective To investigate the anaesthetic effect of propofol combined with remifentanil by target-controlled infusion (TCI) used in gynecological laparoscopic myomectomy.Methods Fifty cases,who were scheduled for gynecological laparoscopic myomectomy in our hospital from June 2010 to June 2011,was randomly divided into propofol combined with remifentanil group (n =25) and inhalation anesthesia (remifentanil combined with sevoflurane) group (n =25).The heart rate and blood pressure were recorded at the time of before induction of anesthesia (T0),30 min after carbon dioxide pneumoperitoneum,the end of operation and 3 min after extubation.The awake time,time of extubation and surgery time were also recorded.Results The hemodynamics were kept stable in propofol combined with remifentanil group,and there were no significant difference with respect to SABP,DABP and heart rate at all time points compared with baseline (P ＞0.05) in propofol group.However,in inhalation anesthesia group,SABP,DABP and heart rate were increased significantly at 30 min after carbon dioxide pneumoperitoneum and 3 min after extubation when compared with baseline (P ＜ 0.05) and were higher than those of propofol group (P ＜ 0.05) at counterpart time points.In inhalation anesthesia group,the awake time ((9.3 ± 1.5) min vs (4.9 ± 1.1) min,t =10.56,P =0.017) and time of extubation ((12.9 ± 2.4) min vs.(6.8 ± 1.2) min,t =12.36,P =0.01) were significantlv longer than that of propofol group (P ＜ 0.05).Conclusion Propofol combined with remifentanil TCI-based anesthesia could achieve the optimal hemdynamic stability during anesthesia maintance and better recovery profile from anesthesia in gynecological laparoscopic myomectomy.

Objective To prospectively evaluate the value of US,MSCT,EUS and MRI in the quantitative evaluation of the extent of pancreaticobiliary duct obstruction in pancreatic cancer.Methods Consecutive 68 patients with pancreatic carcinoma underwent US,MSCT,EUS and MRI before surgery.The diameter of extrahepatic bile duct and pancreatic duet were measured,and correlation analysis was performed with surgical specimens.Results Diameters of extrahepatic bile duct scaled by US.MSCT,EUS and MRI were(16.60±6.33)mm,(18.90±6.74)mm,(18.80±5.88)nun and(17.26±4.83)mm,and diameter measured from surgical specimens was(18.39±6.05)mm;the correlation among the four imaging examinations and the surgical evaluation were r=0.3839,P=0.1055;r=0.7113,P=0.0011; r=0.3759,P=0.0465;r=0.3376,P=0.2872,respectively. Kappa Values were 0.6285,0.7115,0.6661 and 0.7490,respectively.The diameter of pancreatic duct was(15.90±3.41)mm,(6.83 4-3.70)mm,(6.77±3.22)mm and(5.58±2.65)mm,and diameter measured from surgical specimens was(5.97±2.60)mm,the correlation among the four imaging examinations and the surgical evaluation were r=0.3584,P=0.2895;r=0.6148,P＜0.0001; r=0.7373,P＜0.0001;r=1.0746,P＜0.0001.Kappa values were 4.159,9.094,9.001 and 4.050.All of these parameters were in coherence with surgical findings.Condusions US could be used as the initial method in the assessment of extrahepatic and pancreatic duct obstruction.MRI and MSCT,combined with EUS if necessary,could be used to quantitatively evaluate the extent of pancreaticobiliary obstruction.

ObjectiveHost mitochondrial DNA （mtDNA） and chloroplast DNA （cpDNA） contamination severely affects high-throughput sequencing of endophytic bacteria in plants. This study aims to explore and evaluate a novel strategy of inhibiting host gene amplification in high-throughput sequencing of endophytic bacteria in medicinal plants. MethodGreen Shield Sequencing （GSS） was introduced in the 16S rDNA polymerase chain reaction （PCR） of endophytic bacteria to shield the non-target amplification of genes in the host （Ligusticum chuanxiong）. The performance was compared between GSS-PCR and conventional PCR in the high-throughput sequencing of endophytic bacteria and rhizosphere soil bacteria. ResultCompared with conventional PCR， GSS-PCR significantly reduced the amplification of mtDNA and cpDNA in L. chuanxiong in high-throughput sequencing， decreasing the non-target genes by more than 60%. Moreover， this strategy significantly increased the diversity of endophytic bacteria and multiplied the species without compromising the extraction of the information about the dominant bacteria. The GSS amplification of 16S rDNA V4 region of L. chuanxiong showed lower host contamination rate and higher endophytic bacterial diversity than that of V3-V4 regions. ConclusionGSS can significantly reduce host gene contamination in the high-throughput sequencing of L. chuanxiong endophytic bacteria and improve the accuracy of endophytic bacterial diversity analysis at the same sequencing depth， thus improving the high-throughput analysis quality of endophytic bacteria in plants. Accordingly， this strategy improves the feasibility and reliability of high-throughput sequencing for the 16S rDNA V3-V4 and V4 regions of endophytic bacteria. GSS used in this study provides a method reference for studying the endophytic bacteria in other medicinal plants.

【Objective】 To investigate the establishment of multi-center haemovigilance (HV) and the monitoring of adverse reactions to blood donation (ARBD), in order to provide basis for the management of blood donors. 【Methods】 The operation of HV was investigated by questionnaire. The total number of blood donations (including plateletpheresis) and ARBD cases occurred in each blood center from 2014 to 2018 were analyzed. 【Results】 Among the 24 blood centers in this survey, only nine got HV operated. The incidence of ARBD of 19 blood centers that fulfilled the questionnaire was in the range of (0.003~1.151) %. The change trend of number and incidence of ARBD cases were indeterminate. 【Conclusion】 Most blood centers did not got HV established. The incidence of ARBD varied greatly and was indeterminate. The application of HV should be further improved to strengthen ARBD management.
