Objective:To explore the anti-inflammatory effects and the underlying mechanisms of ethanol extract of Ageratum cony-zoides. L. from Guangxi. Methods:The auricle edema model was induced by dimethylbenzene in the mice and the paw edema model was induced by carrageenan respectively in the mice and rats to study the anti-inflammatory effects of ethanol extract of Ageratum cony-zoides. L. from Guangxi. The content of malondiadehyde (MDA) and proateglandin E2 (PGE2), and the activity of superoxide dis-mutase( SOD) in the mouse edema paw was measured. The contents of tumour necrosisfactor-α ( TNF-α) , interleukin-1β ( IL-1β) and interleukin-6(IL-6) in the rat serum were detected as well. Results:Compared with the model control group, the ethanol extracts of Ageratum conyzoides. L. from Guangxi could remarkably inhibit auricle edema in the mice and paw edema in the mice and rats( P<0. 05 or P<0. 01), the inhibition ratio for high, medium and low dosage group(6. 0, 3. 0, 1. 5 g·kg-1)was 29. 24%,16. 42% and 11. 21% in the auricle edema mice and 28. 66%,18. 79% and 13. 13% in the paw edema mice , respectively. It could remarkably re-duce MDA and PGE2 content and enhance the activity of SOD in the mouse inflammatory tissue(P<0. 05 or P<0. 01). In the paw e-dema rats, the inhibition ratio for high, medium and low dosage group(4. 5,2. 3, 1. 2 g·kg-1)was 43. 69%, 36. 01% and 23. 29%at the 3rd h, respectively , and it also could remarkably reduce serum TNF-α, IL-1βand IL-6 content(P<0. 05 or P<0. 01). Con-clusion:The ethanol extracts of Ageratum conyzoides. L. from Guangxi show significantly anti-inflammatory effects, and the mecha-nisms may be related to the ability of scavenging oxygen free radicals and reducing the release of inflammatory cytokines and proinflam-matory cytokines.

Objective To investigate the efficacy of preemptive analgesiawith ultrasound-guided modified dorsal penile nerve block combined ketorolac tromethamine for circumcision in pediatric patients.Methods Forty-five pediatric patients with ASA grade Ⅰ undergoing elective circumcision were randomly divided into 3 groups (n=15 each).The same intravenous compound anesthesia was used in the three groups.The pediatric patients underwent ultrasound-guided modified dorsal penile nerve block with a mixture of 0.1 ml/kg of 0.2% ropivacaine and 0.8% lidocaine before operation in group A and group B.The pediatric patients were given ketorolac tromethamine 1 mg/kg intramuscular injection before operation in group A and group C.The total consumption of propfol and sufentanil, occurrence of intraoperative body movement and respiratory depression, emergence time, time from waking up to going out of PACU and adverse reactions such as postoperative agitation, nausea, vomiting and pruritus were aslo recorded.The requirement for postoperative paracetamol suppositories was recorded.Results Compared with group C, the total consumption of propfol and sufentanil were significantly decreased, incidence of body movement andrespiratory depression were significantly decreased, the emergence time and time from waking up to going out of PACU was significantly shortened, requirement for paracetamol suppositories were significantly decreased in group A and group B(P<0.05).Compared with group B, incidence of requirement for paracetamol suppositories was significantly decreased in group A (P<0.05).No pediatric patients developed postoperative nausea, vomiting, pruritus and incidence of emergence agitation had no statistical difference in the three groups.Conclusion Preemptive analgesia with ultrasound-guided modified dorsal penile nerve block combined ketorolac tromethamine is safe and effective when used for circumcision in pediatric patients, and it has good efficacy of postoperative analgesia.

BACKGROUND: The traditional ankle-foot orthosis focuses on the protection, correction, stability, and compensation;therefore, it is important to explore a new rehabilitation method for ankle joint dysfunction.OBJECTIVE: To explore the effect of computer-aided movable and measurable ankle-foot orthosis that designed by the Department of Rehabilitation in Longgang Central Hospital of Shenzhen on postoperative dysfunction after ankle fracture.METHODS: Fifty-two patients with ankle fractures at 3 weeks after internal fixation were selected and equivalently randomized into two groups. Both groups received conventional oral medication and rehabilitation therapy. In addition,the patients in control group were given joint mobilization treatment, while those in experimental group were given computer-aided movable and measurable of ankle-foot orthosis, 20 minutes daily, 6 days weekly for consecutive 4 weeks. The efficacy was evaluated by muscle strength, active range of motion, Kofoed ankle score and visual analogue scale on computer at baseline, 7, 14, and 28 days after training.RESULTS AND CONCLUSION: (1) There were no significant differences in baseline data and ankle function scores between two groups before training (P > 0.05), and all above indicators were significantly improved in both two groups at 4 weeks after training (P < 0.05). (2) Compared with the control group, the muscle strength, Kofoed ankle score and visual analogue scale scores on computer in the experimental group were significantly improved at 7, 14 and 28 days after training (P < 0.05). (3) The active plantar flexion angle in the experimental group was significantly larger than that in the control group at 28 days after training (P < 0.05).The active plantar flexion and dorsiflexion angles at 7 and 14 days after training, and active dorsiflexion angle at 28 days after training did not differ significantly between two groups (P >0.05). To conclude, the unique ankle-foot orthosis can reduce postoperative pain, enhance muscle strength and improve ankle mobility after ankle fracture.

This article was aimed to study the effect of geniposide in hyperuricemia mice. Different doses (50, 100, 200 mg·kg-1) of geniposide were administrated to hyperuricemia mice induced by potassium oxonate by gavage for seven consecutive days. Then, serum uric acid (SUA), urinary uric acid (UUA) and the hepatic xanthine oxidase ac-tivities (XOD) of mice were detected. The results showed that the middle- and high-dose groups of geniposide re-duced the level of SUA significantly (P<0.01). It was concluded that geniposide can reduce the level of SUA in hy-peruricemia mice by promoting UUA excretion.

Objective This present study was to examine the prevalence and determinants of one-night-stand behavior among young men who have sex with men (YMSM).Methods A total of 403 YMSM aged 16 to 25 were recruited through internet promotion,extending activity and HIV VCT in Wuhan.Data was gathered through anonymous questionnaire.Binary logistic regression was used to examine factors associated with one-night-stand behavior.Results Of the 398 YMSM,48.99％ (195/ 398) reported having had casual sex in the last 6 months.Of the ones having had casual sex,34.29％ (60/175) and 28.65％ (49/171) reported using condoms consistently during anal or oral sexual contacts,respectively.These figures were lower than those of YMSM not having casual sexual contacts [with anal sex as 49.08％ (80/163) and oral sex as 38.85％ (61/157)].76.80％ (149/194) of the YMSM reported having had multiple sexual partners,with the figure higher than those without [33.15％ (60/ 181)] (P＜0.01).Results from the logistic regression analysis showed that the following factors seemed to be associated with casual sex activities among YMSM,including:often using intemet,(OR=4.89,95％ CI:1.90-12.54),taking illegal drugs (OR=2.72,95％ CI:1.60-4.63).Conclusions YMSM who bad engaged in casual sex,practicing unprotected sex or having multiple sexual partners,were recognized as high risk population.Targeted intervention programs are needed to decrease the one-night-stand behavior.Internct intervention strategy seemed an important method to serve the purpose.

Objective: To investigate the expression of transcription factor AT-rich interaction domain 3a (ARID3a) in peripheral blood B cells of patients with systemic lupus erythematosus (SLE) and its clinical significance. Methods: Peripheral blood mononuclear cells were isolated from 17 SLE patients and 13 healthy controls. Then, the expression of ARID3a by B cells was determined by flow cytometry. Data was analyzed with independent sample t test. The correlations between the frequencies of ARID3a⁺ B cells and clinical indicators of SLE patients were assessed by Pearson cor relation analysis. The expression of ARID3a in kidney was detected by immunohistochemistry in 14 cases of lupus nephritis (LN). Results: The percentages of ARID3a⁺ B cells in SLE patients [(51.6±3.2)%] were significantly higher than those in healthy controls [(32.6±3.4)%](t=4.0, P<0.01). There was a positive correlation between the percentages of ARID3a⁺ B cells in SLE patients and their 24-hour urinary protein (r=0.68, P<0.05). Furthermore, the percentages of ARID3a⁺ B cells in peripheral blood from patients with active LN[(62.3±4.3)%] were remarkably higher than that from patients without LN or with inactive LN [(43.3±2.8)%] (t=3.8, P<0.01). The expression of ARID3a in glomerula and tubules of LN patients markedly increased. Conclusion Elevated expression of transcription factor ARID3a in B cells may participate in the pathogenesis of LN.

Objective:To investigate the correlation between subclinical hypothyroidism(SCH)and the degree of coronary artery stenosis in patients with coronary heart disease.Methods:From March 2018 to September 2019, 138 patients undergoing coronary angiography in our hospital were randomly selected and their serum thyroxine(FT4)and high-sensitivity thyroid stimulating hormone(sTSH)levels were measured.Based on the levels of FT4 and sTSH, patients were divided into the SCH group and the normal group.Combined with coronary angiography results, the correlation between the SCH and the number of coronary lesions were analyzed.Results:Patients in the SCH group were associated with significantly higher levels of cholesterol(TC)[(5.83±1.27)mmol/L vs.(5.02±1.22)mmol/L, t=3.746, P=0.000], triglyceride(TG)[(3.29±1.74)mmol/L vs.(2.17±1.68)mmol/L, t=3.769, P=0.000], low-density lipoprotein cholesterol(LDL-C)[(3.81±1.02)mmol/L vs.(3.24±1.08)mmol/L, t=3.092, P=0.001], and high-density lipoprotein cholesterol(HDL-C)[(1.13±0.27)mmol/L vs.(1.02±0.25)mmol/L, t=2.4459, P=0.008]than those in the normal group.There were significant differences in sTSH levels between patients with multivessel, double vessel or single vessel disease when grouped by the number of coronary lesions, and between those with severe, moderate or mild coronary artery stenosis when grouped by disease severity(all P<0.05). Multiple regression analysis showed that SCH, TC, and LDL-C were factors affecting the number of coronary lesions( P<0.05). Conclusions:SCH is an important factor that causes the occurrence and progression of coronary artery stenosis in patients with coronary heart disease, mainly by affecting lipid metabolism.
