Measurement of whole blood CL was carried out to evaluate phagocytic of function of PMNL and opsonic activity of plasma from children (22 cases), adults (31), newborn infants (umbilical cord blood, 21), patients with bacterial infection (31), viral infections (21),and mild anemia (10). The following results were obtained: first, phagocytic function of PMNL and opsonic activity of plasma from normal children was compared to adults; second, phagocytic and/or metabolic activity of PMNL and opsonic ativity of plasma from newborn infants were lower then normal, third, PMNL of the patients with bacterial infections had been preactivated in vivo, their phagocytic function being enhanced, but, blood from the patients with viral infections showed almost no abnormalities; fourth, phagocytic activity of PMNL from the patients with mild anemia was similar to normal human. The significance of the results was also discused in the paper.

Objective To study the tissue-specificity of ?-carotene-15,15’-monooxygenase(? CMOOX). Method Semi-quantitative RT-PCR and HPLC were used to study the expression of ?CMOOX mRNA and its activity in different tissues of chicken. Results ?CMOOX mRNA was expressed in tissues including heart, liver, spleen, lung, kidney, duodenum, jejunum, ileum, muscle and testis, not expressed in lung. Furthermore, it was expressed in jejunum with the highest level. ?CMOOX activity was found in every tissue, except lung, and highest in duodenum and jejunum. Conclusion The distribution of ?CMOOX in chicken has tissue specificity.

Objective To investigate the association of two single nucleotide polymorphisms (SNPs),rs844648 and rs3850641,in OX40L (TNFSF4) gene,with systemic lupus erythematosus(SLE) in Hubei Han populations.Methods A total of 82 patients with SLE and 100 normal human controls were eligible for this study.Blood samples were obtained from these subjects and DNA was extracted from these samples.PCR-restriction fragment length polymorphism (PCR-RFLP) was used to analyze the genotype of SNPs rs844648 and rs3850641.Results The frequency of AA,AG and GG genotype of the SNP rs844648 was 14.0％,55.0％and 31.0％ respectively in the controls,20.7％,62.2％ and 17.1％ respectively in the patients.A higher frequency was observed for A allele at the SNP rs844648 and G allele at the SNP rs3850641 in patients compared with the normal controls [73.2％ vs.69.0％％,x2 =4.69,P ＜ 0.05,OR =2.182 (1.068 - 4.458);37.8％ vs.24.0％,x2 =4.07,P ＜ 0.05,OR =1.925 (1.015 - 3.651)].The frequency of AA,AG and GG genotype of SNP rs3850641 was 76.0％,21.0％ and 3.0％ respectively in the normal controls,62.2％,31.7％ and 6.1％ respectively in the patients.Conclusions There are polymorphisms in the SNPs rs844648 and rs3850641 in TNFSF4 gene,which may be associated with the development of SLE.

Ralstonia metallidurans CH34 was isolated from the deposit of a znic factory .The degradation of phenol by R .metallidurans CH34 was investigated. The results showed that R . metallidurans CH34 possesses high ability to degrade phenol with the biodegradation rate constant of 0.33 . The optimal pH , temperature and volume of medium for phenol degradation are pH 7.0 , 30℃ , and 20%(v/v), respectively . In addition , this strain retains its ability to degrade phenol in the presence of high concentration of heavy metal ion .The sodium citrate , sodium succinate can enhance the degradation of phenol.

Objective: To investigate the effects of adrenaline on pharmacodynamics and pharmacokinetics of bupivacaine for interscalene plexus block. Method:Sixteen ASA gradeⅠ-Ⅱadult patients undergoing shoulder or upper limbs operation were randomly divided into two groups (n=8)). The plexus block was induced with 0.75％ bupivacaine 2 mg/kg or 0.75％ bupivacaine 2mg/kg plus 1:200 000 adrenaline. Clinical effects and plasma concentration,the Cmax and Tmax were compared between two groups. Result:The time to reach peak analgesia and the duration of analgesia were longer in adrenaline group than in control group(P

This study was aimed to observe the influence of water-solubility nipponica saponin on activation of TNF-α+IL-17-induced rat fibroblast-like synovial cell line RSC-364 cellular model nuclear transcription factor NF-κB pathway as well as TNF-α, IL-1, ICAM-1, MMP-2, MMP-3 secretion. IL-17+ TNF-α were used for stimulating RSC-364 to establish rheumatoid arthritis (RA) cellular model. Water-solubility nipponica saponin in different con-centrations was used for intervention. The influence of water-solubility nipponica saponin in different concentrations on cell viability was detected by semi-quantitative RT-PCR method. Changes in the level of TNF-α, IL-1, ICAM-1, MMP-2, and MMP-3 of culture supernatant were detected by ELISA. The results showed that the activation of NF-κB p65 in RSC-364 stimulated by TNF-α+ IL-17 can be inhibited by water-solubility nipponica saponin ac-cording to its concentration. It improved IκB-α expression, and inhibited TNF-α, IL-1, ICAM-1, MMP-2 and MMP-3 secretion. It was concluded that water-solubility nipponica saponin can inhibit the activation of NF-κB pathway, hinder the secretion and activation of multiple downstream genes, which may be its effect in inhibiting syn-ovial inflammation in RA.

Objective:To investigate the effect of short single reverse-α fixation of nasobiliary tube after endoscopic nasobiliary drainage.Methods:From January 2019 to October 2019, the patients who performed with endoscopic nasolbiliary drainage in Tongji University Affiliated Shanghai East Hospital were randomly divided into experimental group (short single reverse-α fixation, 155 cases) and control group (routine reverse-α fixation, 137 cases). The incidences of the fixation time, prolapse rate, nursing time, scores of nasal comfort and bile flow rate of nasobiliary duct were evaluated between the two groups.Results:The average time of nasobiliary duct fixation was (18.31±1.67) s, the prolapse rate was 5.2% (8/155) and the time of nursing was (35.03±2.68) s, which were lower than those of the control group (46.50±5.50) s, 13.9% (19/137) and (72.07±7.63) s. The difference was statistically significant ( t or χ 2 values were 60.795, 6.570, 56.629, P<0.01 or 0.05). The comfort score of the experimental group was (4.61±1.06) points, the bile flow rate was (241.52±53.95) ml/days, which were higher than (5.76±0.76) points and (174.09±47.55) ml/days of the control group, the difference was statistically significant ( t values were 10.448, 11.265, P<0.01). Conclusions:Shortening the length of nasobiliary duct combined with single reaction "α" method has the advantages of simper operation and nursing, low prolapse rate, high comfort and good drainage effect. It is worthy of clinical application.

To examine whether or not the regulatory sequence of chicken ovalbumin gene can drive transgene expression specifically in hen oviduct, the authors constructed an oviduct-specific expression vector (pOV), containing 3.0 kilobases (kb) of the 5'-flanking sequence and 3.0 kb of the 3'-flanking sequence of the chicken ovalbumin gene. Jellyfish green fluorescence protein (EGFP) reporter gene and bacterial LacZ reporter gene were respectively inserted into the downstream of the 5'-regulatory region.The recombinants were named as pOVEGFP and pOVLacZ. Two transfer systems, in vitro and in vivo, were used to verify the function of the vector. In vitro, the plasmid DNA pOVEGFP and pEGFP-N1 were transfected respectively by the polyethyleneimine procedure into the primary chicken oviduct epithelium (PCOE) and fibroblasts cells isolated from laying hens. In vivo, the recombinant vector pOVLacZ was injected into egg-laying hens via wing vein and the tissues were collected for RT-PCR analysis.The results showed that expression of pEGFP-N1 was achieved at low level in oviduct epithelial cells and at high level in fibroblasts, but that the recombinant vector was not expressed in both cells. RT-PCR analysis showed that the LacZ gene was transcribed in the oviduct, but not in the heart, liver, kidney and spleen of the injected hens. Accordingly, the ?-galactosidase activity was only detected in the oviduct magnum (116.7 mU/ml) and eggs (16.47 mU/ml). These results indicated that the cloned regulation regions of chicken ovalbumin gene could drive exogenous gene expression specifically in the oviducts of hens. In vivo gene injection via wing vein may serve as a rapid production system of recombinant proteins in chicken eggs. In addition, the cultured primary oviduct cells from laying hens were not efficient temporary expression systems for analyzing the function of regulating elements of ovalbumin gene.
