Objective To analyze the prevalence of brucellosis with the initial symptom of fever in non-pasture area and to investigate the method of early diagnosis.Method Clinical features including symptoms,blood routine tests,blood cultures,rose-bengal plate agglutination tests,treatment and follow-up were analyzed in 18 patients with brucellosis admitted to the Department of Infectious Diseases,Tianjin First Centre Hospital from January 2010 to June 2013.Results Middle-aged men with history of smoking and drinking accounted for the majority of patients with initial symptom of fever.Twelve were not complicated with any underlying diseases.Twelve had no contact history.Four had history of farm animal contact,one had history of consuming raw meat products,and one had history of dog raising.All of them had fever,15 of which had hyperpyrexia and 13 had irregular fever.White cells in blood routine test were normal in 12 cases,decreased in 6 cases.And the proportion of rhabditiform nucleus neutrophil increased.Six showed neutrophil left shift.Blood platelet decreased in 3 cases.Thirteen cases showed increased alanine aminotransferase and aspartate aminotransferase.C-reactive protein was elevated in 14 cases.Twelve cases had positive culture of Brucella melitensis in blood or bone marrow culture.Eighteen cases had positive results of rose-bengal plate agglutination test.The proportions of neutrophil and lymphocyte were normal.The treatment included moxifloxacin,levofloxacin,isepamicin,etimicin,amikacin,rifampicin,minocycline.The regimens were usually two or three drugs in combination.The duration of follow-up ranged from 4 to 11 months with good prognosis.Conclusions Patients from nonpasture area with initial symptom of fever could be brucellosis.Clinician should be alert to the disease and inquiry contact history in detail.Brucella serology test should be performed.Early diagnose and prompt treatment could avoid serious complications.

OBJECTIVE:To systematically review the efficacy of Duhuo jisheng decoction combined with chemical medicines in the treatment of ankylosing spondylitis (AS),and to provide reference for clinical treatment. METHODS:Retrieved from CBM,CJFD,VIP,Wanfang Database,PubMed and EMBase,randomized controlled trials(RCT)about Duhuo jisheng decoction combined with chemical medicines(test group)versus chemical medicines alone(control group)in the treatment of AS were col-lected,Meta-analysis was performed by using Rev Man 5.3 software after data extraction and quality evaluation. RESULTS:Total-ly 6 RCTs were included,involving 382 patients. Results of Meta-analysis showed,the total effective rate [RR=1.35,95%CI(1.20, 1.52),P<0.001],improvement rate of TCM symptoms [RR=1.31,95%CI(1.09,1.57),P=0.004)in test group were significantly higher than control group,and CRP level was lower than contxol group[MD=-6.18,95%CI(-8.49,-3.87),P<0.001],the dif-ference was statistically significant. CONCLUSIONS:Duhuo jisheng decoction combined with chemical medicines shows better effi-cacy than chemical medicines alone,it can improve the TCM symptoms and decrease the CRP level.

Objective To study the effect of adaptive support ventilation (ASV) in treatment of severe asthma.Methods Forty-nine cases of severe asthma were divided into ASV group (25 cases) and control group (24 cases,tradition mechanical ventilation).The arterial blood gas,respiratory dynamics,mechanical ventilation time,hospital stay and thorax barotrauma was compared between two groups.Results The arterial blood gas and respiratory dynamics was improved after mechanical ventilation compared with that before mechanical ventilation in two groups,and there was significant difference (P ＜ 0.05 or ＜ 0.01).The airway peak voltage,lung dynamic compliance and platform pressure after mechanical ventilation of 2,12 and 24 h in ASV group was better than that in control group[2 h:(33 ± 12) cm H2O(1 cm H2O =0.098kPa) vs.(37 ± 11) cm H2O,(16 ± 9) ml/cm H2O vs.(17 ± 10) ml/cm H2O,(27 ± 6) cm H2O vs.(30 ±12) cm H2O; 12 h:(23 ± 12) cm H2O vs.(25 ± 11) cm H2O,(28 ± 6) ml/cm H2O vs.(23 ± 10) ml/cm H2O,(20 ±6) cm H2O vs.(25 ±4) cm H2O; 24 h:(18 ± 12) cm H2O vs.(20 ± 11) cm H2O,(32 ±9)ml/cm H2O vs.(28 ± 10) ml/cm H2O,(12 ±7) cm H2O vs.(16 ±7) cm H2O],and there was significant difference(P＜ 0.05 or ＜ 0.01).The mechanical ventilation time and hospital stay in ASV group was shorter than that in control group [(46 ± 8) h vs.(56 ± 6) h,(7 ± 2) d vs.(10 ± 3) d],and there was significant difference (P＜ 0.01).The thorax barotrauma was not observed in ASV group; 3 cases showed subcutaneous emphysema and 2 cases showed pneumothorax in control group.Conclusions ASV mode could decrease airway peak voltage and platform pressure,improve arterial blood gas and lung dynamic compliance,shorten mechanical ventilation time and hospital stay.It is safe and effective for patients with severe asthma.

AIM: To investigate the effect of deoxycholic acid (DCA) on the energy metabolism in human normal colon epithelial NCM460 cells.METHODS: NCM460 cells was treated with DCA at 10, 30 and 100 μmol/L for 5 d, or DCA at 100 μmol/L for 3, 5 and 7 d.After treated with DCA at 100 μmol/L for 3 d, the cells were treated with resveratrol, the activator of sirtuin 3 (SIRT3), for the next 4 d.Adenosine triphosphate (ATP) production in the mitochondria and lactate acid level were detected.The protein expression of SIRT3 was determined by Western blot.RESULTS: DCA inhibited the ATP production, increased lactate acid level, and downregulated the protein expression of SIRT3 in a dose-and time-dependent manner.Resveratrol at 10 μmol/L reversed the effects of DCA on the NCM460 cells.CONCLUSION: DCA induces the dysfunction of energy metabolism in NCM460 cells, and the mechanism may be related with SIRT3.

Objective To evaluate the clinical outcomes of severely resorbed edentulous mandibles with tilted implants and fixed prostheses. Methods Ten patients with severely resorbed edentulous mandibles were en-rolled. Each patient received 4 implants,two posteriors placed tilted implants. Immediate loading of tilted implants were applied in all cases using a fixed provisional prosthesis. All patients were finalized 3-4 months with fixed pros-theses. Results 40/40 implants with initial torque(>35N.cm)were followed 1-1.5 years presenting 100%surviv-al. Conclusion The method of using tilted implants and fixed prostheses in the cases of severely resorbed edentu-lous mandibles can achieve an ideal short-term and medium-term effects.

Objective To explore the risk factors that may cause recurrent retinal detachment in rhegmatogenous retinal detachment(RRD)patients after surgery.Methods A total of 403 patients(403 eyes)with RRD diagnosed in the Department of Ophthalmology of the First Affiliated Hospital of Soochow University from October 2020 to April 2022 were included in this study.Among them,35 patients underwent the scleral buckling,79 patients underwent the pars plana vit-rectomy(PPV)+intravitreal gas tamponade,222 patients underwent the PPV+intravitreal silicone oil tamponade,and 67 patients underwent the PPV+vitreous silicone oil tamponade+silicone oil removal.The postoperative follow-up lasted for at least 3 months.Risk factors affecting one-time retinal reattachment after RRD surgery were analyzed by univariate and multivariate Logistic analyses,and Logistic regression was applied to construct a risk prediction model.Results Among the 403 eyes with RRD,369 eyes had retinal reattachment on the first try,and 34 eyes did not,with a one-time reat-tachment rate of 91.6％.The univariate analysis showed that the differences in axial length(AL),surgical approach,loca-tion of the tear,and size of the tear between patients with one-time retinal reattachment and those without reattachment were statistically significant(all P＜0.05).From the regression equation,it was found that the risk of non-reattachment af-ter RRD surgery of patients with an AL ≥ 26 mm was 4.248 times higher than those with an AL＜26 mm(P＜0.05).The multivariate Logistic regression analysis showed that AL,location of the tear,size of the tear,and surgical approach were risk factors for non-reattachment after RRD surgery(all P＜0.05).The Hosmer-Lemeshow test yielded P=0.165.The re-sults of the receiver operating characteristic curve analysis showed that the area under the curve to predict whether retinal re-detachment occurs after RRD surgery was 0.892(95％CI:0.832-0.953),and the sensitivity and specificity were 79.4％and 87.3％,respectively(P＜0.05).Conclusion AL is an independent risk factor for retinal re-detachment after RRD surgery.The prediction model constructed based on AL,location of the tear,size of the tear,and the surgical method can accurately predict whether retinal detachment will occur after RRD surgery.
