Objective To compare the clinical effect of different administration methods of carboprost tromethamine for the treatment of scar uterus with cesarean resection.Methods 120 cases of puerpera with uterine scar uterus and postpartum hemorrhage tendency were selected,and the history of cesarean section was once and more than once.According to the digital table,they were randomly divided into observation group(60 cases)and control group(60 cases),the observation group was divided into single carboprost tromethamine administration group(30 cases) and sub carboprost tromethamine administration group (30 cases).The clinical efficacy of the three groups were compared.Results In the observation group,the incidence rates of postpartum hemorrhage(13.33%,10.00%)were significantly lower than 28.33% in the control group(χ2 =10.844,6.822,all P <0.05).The incidence of postpartum hemorrhage of the single carboprost tromethamine administration group and sub carboprost tromethamine administration group(13.33% vs.10.00%)showed no statistically significant difference(χ2 =0.538,P >0.05).24h postpartum hemorrhage in the observation group[(263.11 ±137.04)mL,(359.98 ±212.35)mL]were significantly lower than those of the control group[(461.52 ±127.67)mL](t =5.795,2.247,all P <0.05).24h postpartum hemorrhage of the sub carboprost tromethamine administration group[(263.11 ±137.04)mL]was significantly less than that of the single carboprost tromethamine administration group[(359.98 ±212.35)mL,t =2.097,P <0.05].There was no statistically significant difference in the adverse reactions among the three groups(P >0.05).Conclusion Carbo-prost tromethamine can significantly reduce the bleeding rate of uterine scar again after cesarean section,sub carbo-prost tromethamine administration can significantly reduce the amount of bleeding in postoperative 24h,it is worth popularizing in clinical.

MicroRNA (miRNA) is newly discovered,a class of small non-coding RNA which plays critical roles in the regulation of gene expression at the posttranscriptional level by either degrading or blocking translation of messenger RNA targets.Growing evidence that some miRNAs have crucial roles in controlling and modulating immunity,while dysregulation of miRNAs can lead to autoimmunity,and miRNA-146 seems to be a popular topic discussed much.Thyroid associated ophthalmopathy (TAO) is an organ specificity autoimmune disease which is closely associated with Graves disease.Although many clinical and experimental investigations have been done,the precise aetiology and pathogenesis of TAO remain largely unclear.Here we review the roles of miRNA-146 regulation in immune functions and in the development of autoimmunity and autoimmune disease,and outlook for the roles of miRNA-146 in the pathogenesis of TAO.

OBJECTIVE: To investigate the effect of bromocriptine on the expression of Pit-1 in prolactinoma rats. METHODS: Firstly, to prepare prolactinoma model in rats. Adult Wistar rats were divided into two groups at random. The rats in control group were subscutaneously implanted with a blank implant. Rats in 17β-estradiol group were implanted with 17β-estradiol-containing implants. Secondly, rates in 17β-estradiol group were divided into two groups at random: model group and bromocriptine group. Water was administrated to rats in model group. Bromocriptine (0.225 mg · kg-1 · d-1) were orally administrated to rats in bromocriptine group, the rats in control group were orally administrated with water. After four weeks of treatment, all the animals were executed. Each pituitary gland was weighed. Serum prolactin (PRL) levels were measured by RIA method. Pit-1 mRNA levels in pituitaiy tissue were measured by RT-PCR method. RESULTS: The weights of pituitary gland and PRL levels in 17β-estradiol group were individually higher than those in control group (P<0.001). The expression levels of Pit-1 mRNA in bromocriptine group was obviously lower than that in model group (P≤0.001). CONCLUSION: Bromocriptine has potential preventive effect to estrogen-induced rat prolactinoma. The decrease of Pit-1 mRNA level may be involved in the mechanism of anti-prolactinoma effect of bromocriptine.

OBJECTIVE: To study the effects of total saponin of Rhizoma Dioscreae Nipponicae (TSRDN) on the expression of vascular endothelial growth factor (VEGF), angiopoietin-2 (Ang-2) and receptor Tie-2 in synovial tissue of collagen-induced arthritis (CIA) rats, and to investigate the antiangiogenesis mechanism of TSRDN in treating rheumatoid arthritis. METHODS: After the CIA rat model was successfully established, the rats were randomly divided into 5 groups: normal control group, CIA model group, TSRDN group, tripterygium group, and diosgenin group. Real-time PCR was used to detect VEGF mRNA expression in synovial tissue of CIA rats, and immunohistochemical staining was used to observe angiopoietin-2 and receptor Tie-2. RESULTS: VEGF mRNA, Ang-2 and Tie-2 expressions in synovial tissue of CIA rats were obviously higher than normal control group (P < 0.01). After treatment with TSRDN, tripterygium, and diosgenin, the expressions of VEGF mRNA and Ang-2 were obviously lower than those in CIA model group (P < 0.01). But Tie-2 expression showed decreasing trend, and there was no obvious differences between each treatment group. VEGF mRNA expression in TSRDN group was much lower than that in tripterygium group and diosgenin group. CONCLUSION: TSRDN can inhibit angiogenesis in synovial tissue by down regulating expressions of VEGF, Ang-2 and receptor Tie-2.

Antimicrobial susceptibility testing (AST) is an important means to clinical microbiology. At present, there are no standard AST methods for aquatic pathogens comparing with human and veterinary pathogens. We reviewed the recent research progress on establishing these methods and discussed the key factors in AST of aquatic pathogens. Furthermore the defect of AST of aquatic pathogens in China was profiled and prospect for further research was put forward.

Abstract: Objective　To determine the rate of nasal carriage Staphylococcus aureus among healthcare workers in Department of Infectious Diseases department of the First Affiliated Hospital of Xi'an Jiaotong University Hospital, and to perform characterization on isolated strains. Methods　A cross-sectional study was performed on 86 healthcare workers from February 2022 to June. Nasal swabs were collected from the healthcare workers, and S. aureus were identified after incubation. Antibiotic susceptibility, including chlorhexidine and mupirocin, was assessed by disk diffusion and minimal inhibitory concentration method. The PCR technique was used to detect the biocide resistance genes (qacAB, smr, lmrS mepA, and sepA), virulence genes (pvl, fnbA/fnbB, sea, seb, sec, sed, tst, eta, etb) and mecA gene. SCCmec typing and multilocus sequence typing was performed. For mupirocin-resistant strains, PCR amplification and sequencing were used to identify whether the strains had ileS gene mutations or carried resistant genes (mupA and mupB). Results　S. aureus was isolated from 37 of the 86 healthcare workers (43.02%) , including 13 methicillin-resistant Staphylococcus aureus (MRSA) strains. The strains showed low resistance rates to levofloxacin (2.70%, 1/37), chloramphenicol (8.11%, 3/37), tetracycline (8.11%, 3/37), gentamicin (10.81%, 4/37), and ciprofloxacin (10.81%, 4/37). A total of 17 strains were identified as multidrug-resistant strains. Four SCCmec types were identified in MRSA strains, with the type II being the most frequent (53.85%, 7/13), followed by type IV (30.77%, 4/13). ST59 (46.15%, 6/13) was the most frequent among MRSA strains, while ST5 (41.67%, 10/24) was the most frequent among methicillin-susceptible S. aureus (MSSA) strains. sea was the most frequent virulence gene (56.76%, 21/37). sepA and mepA were detected in all 37 isolates. One Staphylococcus aureus strain was not sensitive to chlorhexidine, two strains had the missense mutation V588F (G1762T) and showed low level resistance to mupirocin, and one strain carrying mupA gene was highly resistant to mupirocin. Conclusion　The nasal colonization rate of Staphylococcus aureus among healthcare worker in the investigated hospital was high, indicating a risk for nosocomial infections. Strengthened monitoring and decolonization treatment should be carried out to reduce these risks.
