Acupoint Injection Decreases Anesthetic Cosumption during Combined Spinal-Epidural and Patient-Controlled Epidural Labor Analgesia / 中国结合医学杂志

OBJECTIVE@#To explore if acupoint injection can improve analgesic effects or delivery outcomes in parturients who received combined spinal-epidural analgesia (CSEA) and patient-controlled epidural analgesia (PCEA) for labor analgesia.@*METHODS@#A total of 307 participants were prospectively collected from July 2017 to December 2019. The participants were randomized into the combined acupoint injection with CSEA plus PCEA group (AICP group, n=168) and CSEA plus PCEA group (CP group, n=139) for labor analgesia using a random number table. Both groups received CSEA plus PCEA at cervical dilation 3 cm during labor process, and parturients of the AICP group were implemented acupoint injection for which bilateral acupoint of Zusanli (ST 36) and Sanyinjiao (SP 6) were selected in addition. The primary outcome was Visual Analogue Scale (VAS) score, and the secondary outcomes were obstetric outcomes and requirement of anesthetics doses. Safety evaluations were performed after intervention.@*RESULTS@#The VAS scores were significantly lower in the AICP group than in the CP group at 10, 30, 60, and 120 min after labor analgesia (all P<0.05). The latent phase of the AICP group was shorter than that of the CP group (P<0.05). There were less additional anesthetics consumption, lower incidences of uterine atony, fever, pruritus and urinary retention in the AICP group than those in the CP group (all P<0.05).@*CONCLUSION@#Acupoint injection combined CSEA plus PCEA for labor analgesia can decrease the anesthetic consumption, improve analgesic quality, and reduce adverse reactions in the parturients.

Expression and purification of spike protein of severe acute respiratory syndrome coronavirus in Saccharomyces cerevisiae / 中华传染病杂志

Objective To construct the recombinant plasmid pYES6-S and express and purify spike protein of severe acute respiratory syndrome(SANS)coronavirus in Saccharomyces cerevisiae. Methods DNA fragments of SANS coronavirus were obtained by reverse transeription.Four over- lapped fragments of spike protein genes were amplified by polymerase chain reaction(PCR)and ligated into an integral spike protein gene by restriction enzyme digestion.The spike protein gene recombined with pYES6 and cloned into E.coll.The recombinant plasmid pYES6-S was induced and expressed in Saccharomyces cerevisiae(INVScl)by galactose.Results The recombinant plasmid pYES6-S was confirmed that inserted fragment was right in length,direction and base matching by restriction enzyme digestion and sequencing.The purified protein encoded by the whole spike protein gene was about Mr 110?10~3 identified by electrophoresis.Conclusion The whole spike protein gene of SARS coronavirus is cloned into E.coli and the protein is expressed in Saccharomyces cerevisiae successful ly.which can be helpful in SARS vaccine research.

A study of genetic polymorphism of the STR locus D7S2846, D19S400 and D18S535 in Han population in Wenzhou / 法医学杂志

OBJECTIVE@#To study genetic polymorphism of D7S2846, D19S400 and D18S535 in Han population in Wenzhou.@*METHODS@#DNA was extracted with chelex-100 method from EDTA-blood samples of 194 unrelated individuals in Wenzhou and amplified with PCR technique. The PCR products were analyzed by PAG vertical electrophoresis and silver-stain.@*RESULTS@#6 alleles and 15 genotypes of D7S2846, 10 alleles and 36 genotypes of D19S400, 8 alleles and 26 genotypes of D18S535 was observed. The heterozygosities of the three loci are 0.644, 0.724 and 0.772; The power of discriminating are 0.854, 0.940 and 0.938.@*CONCLUSION@#The heterozygosities of the three loci are high and the frequencies was in accordance with Hardy-Weinberg equilibrium (P>0.05), so the three loci can be used in forensic medicine and in other genetic researches.

Polymorphism of STR loci D12S391/D18S865 in Wenzhou Han population / 法医学杂志

OBJECTIVE@#To investigate the polymorphism and forensic efficiency values of STR loci D12S391/D18S865@*METHODS@#Population studies on D12S391 and D18S865 were carried out in a sample of 454 unrelated Wenzhou Han individuals using PCR followed by PAGE and silver stain detection.@*RESULTS@#11/7 alleles and 50/21 genotypes of D12S391/D18S865 were respectively observed among the 454 unrelated individuals. The genotype frequency matched the Hardy-Weinberg equilibrium, The heterozygotes (H) in D12S391/D18S865 were 0.7974/0.7379, Power of Exclusion were 0.9566/0.9077, polymorphism information content (PIC) were 0.8260/0.7279 respectively.@*CONCLUSION@#D12S391 and D18S865 were high polymorphic loci and the frequencies were in accordance with Hardy-Weinberg equilibrium (P>0.5), so the two loci can be used in forensic medicine and in other genetic research areas.
