OBJECTIVE:To observe the efficacy and safety of carboprost and Foley catheter for the expand cervix before hys-teroscopic electric resection. METHODS:80 patients with hysteroscopic operation were randomly divided into research group and control group. Research group was placed inside the vagina carboprost 1 mg 30 minutes before operation;control group was placed inside the Foley catheter 12 hour before operation. The relaxation degree of the cervix,average operative time,preoperative pain, postoperative morbidity and incidence of adverse reactions in 2 groups were observed. RESULTS:There were no significant differ-ences in the relaxation degree of the cervix,postoperative morbidity and incidence of adverse reactions between 2 groups(P>0.05). The average operative time and preoperative pain in research group were significantly better than control group,the differ-ence was statistically significant(P<0.05). CONCLUSIONS:Carboprost and Foley catheter have good efficacy and safety for ex-pand cervix before hysteroscopic electric resection,however,carboprost is better than Foley catheter in terms of average operative time and preoperative pain.

This study was designed to analyze the effect of the mitochondrial respiratory pathways of Candida albicans (C.albicans) on the biofilm formation.The 2,3-bis (2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide (XTT) reduction assay was used to measure the metabolic activities of biofilms formed by the C.albicans which were cultured in the presence of respiratory pathways inhibitors.The biofilms formed by the wide type (WT),GOA1-deleted (GOA31),GOA1-reconstituted (GOA32),AOX1a-deleted (AOX1) and AOX1b-deleted (AOX2) C.albicans strains were examined by the XTT reduction assay and fluorescence microscopy.The expression of adhesion-related genes BCR1,ALS1,ALS3,ECE1 and HWP1 in the biofilms formed by the above five C.albicans strains was detected by real time polymerase chain reaction.It was found that the metabolic activity of biofilms formed by C.albicans was decreased in the presence of alternative oxidase inhibitor whereas it was increased in the presence of classical mitochondrial respiratory pathway complex Ⅲ or complex Ⅳ inhibitor.AOX1 strain produced scarce biofilms interspersed with few hyphal filaments.Moreover,no significant changes in the expression of BCR1 and ALS3 were observed in the AOX1 strain,but the expression of ALS1 and ECE1 was down-regulated,and that of HWP1 was up-regulated.These results indicate that both AOX1 and AOX2 can promote the biofilm formation.However,AOX1a primarily plays a regulatory role in biofilm formation in the absence of inducers where the promoting effect is mainly achieved by promoting mycelial formation.

Objective To explore the relationship between children obesity and adiponectin(ADPN),leptin(LP),and high-sensitive C-reactive protein(hsCRP).Methods Seventy-one obese volunteers as obesity group and 30 normal volunteers who matched obese volunteers in age and sex as control group were selected from 13 702 children and adolescents of 2 to 18 years old in Xiangtan city by sampling survey.The body mass index(BMI),ADPN,LP,hsCRP,fasting blood-glucose(FBG),and fasting pure insulin(INS) were checked respectively.The homeostasis model assessment for insulin resistance(HOMA-IR) and the quantitative insulin-sensitivity check index(QUICKI) were calculated.The difference between the two groups was compared and the relationship of all indexes was analyzed.Results The values of ADPN and QUICKI in obesity group were significantly lower than those of control group(P

Based on Staphylococcus aureus 16S rRNA gene sequences,sequence comparisons have been applied to design a kind of stem-loop structured oligonucleotide probes whose loop sequence mismatched other bacterial strains 16S rRNA gene sequences in more than two positions with high specificity and sensitivity.According to the principle of molecular beacon technology and enzyme linked immunosorbent assay,a method has been evaluated using immobilized stem-loop structured oligonucleotides probe as the conformation switch which is applied to enzymatic detection of nucleic acid targets.As its specificity has been strengthened,the system is able to successfully eliminate false-positive result that is mismatch in an oligonucleotide.Employing a microtiter assay format,4ng of S.aureus 16S rRNA could be detected at least.This approach is more sensitive than other conventional method at least one order of magnitude.

OBJECTIVE: To determine the prevalence of depression and anxiety in patients with psoriatic arthritis (PsA), to investigate whether there is a difference in the prevalence of depression and anxiety between PsA and rheumatoid arthritis (RA) patients and to identify associated risk factors for depression and anxiety in PsA patients. METHODS: PsA and RA patients who visited Department of Rheumatology and Clinical Immunology in Peking University First Hospital from May 2018 to Sep 2019 were recruited. Self-rating anxiety scale and self-rating depression scale were surveyed and compared between PsA and RA patients. Demographics and clinical features including age, gender, disease duration, disease activity score, psoriasis area and severity index (PASI), and medical application were collected. Power Doppler and grey-scale ultrasound of joints, tenosynovitis and enthesis were performed. Multivariate Logistic regression was used to identify the factors associated with mood disorders and the odds ratio of depression and anxiety between the PsA and RA patients. RESULTS: Among the 114 enrolled PsA patients, 37 (32.5%) had mood disorders, in which 36 (31.6%) with depression and 15 (13.2%) with anxiety. Compared with 201 RA patients, PsA patients showed greater odds for depression [adjusted OR (95%CI): 2.7 (1.1-6.4)]. Depression was more often observed in the PsA than in the RA patients (31.6% vs. 18.9%, P=0.011). The similar trend for anxiety was also observed, although the difference was insignificant (13.2% vs. 8.5%, P=0.185). Age (OR=0.95, P=0.008), psoriasis duration (OR=0.94, P=0.018), pain visual analogue scale (OR=1.47, P=0.011), PASI score (OR=1.07, P=0.007) and presence of ultrasound enthesitis (OR=4.13, P=0.009) were identified as factors associated with depression in the PsA patients. PASI score (OR=1.07, P=0.001) was identified as associated factor for anxiety in the PsA patients. CONCLUSION The prevalence of depression and anxiety is elevated in PsA patients. Depression is significantly more prevalent in PsA patients than in RA patients. Younger age, shorter psoriasis duration, worse pain and presence of ultrasound enthesitis are associated with depression, while severe psoriasis rash is associated with both depression and anxiety in PsA patients.

Two endophytic-bacteria isolates of G18 and F19 were isolated from the stem of Taxus chinensis. The G18 and F19 were respectively classified into Psudomonas sp. and Stenotrophomonas sp. based on biological characteristics and 16S rDNA sequence analysis. The bioactivity analysis showed that the fermented broths of the G18 and F19 exhibited antagonistic activities against three pathogenic bacteria, and had good antagonistic effectiveness to Verticillium dahliae and Colletotrichum gloeosporioides, respectively. The G18 can degrade salicylic acid, and the F19 can do dichlorvos.
