Objective:To investigate clinical features, risk factors and prognostic effects of paradoxical response(PR)in children with tuberculous meningitis(TBM)during anti-tuberculosis treatment.Methods:The clinical and follow-up data of TBM children admitted to the Department of Pediatrics, the Affiliated Hospital of Zunyi Medical University between January 2013 and December 2018 were retrospectively analyzed.The children were divided into the PR group and the non-PR group.Influencing factors of PR were selected by the univariate analysis, and independent risk factors were screened from these influencing factors by using the multivariate Logistic regression model.The effect of PR on long-term prognosis (≥9 months) of TBM was evaluated. Results:There were 31 cases(35.6%)with PR among the 87 TBM children enrolled, including 16 boys and 15 girls, with median age of 92(8-168)months.The median time for PR occurrence during the anti-tuberculosis treatment was 33(15-180)days.PR could present dete-rioration or recurrence of original symptoms, cerebrospinal fluid(CSF)deterioration and neuroimaging deterioration, accounting for 71.0%(22/31 cases), 80.6%(25/31 cases)and 51.6%(16/31 cases), respectively.Univariate analysis showed that stage Ⅱ, limb paralysis, cranial nerve palsy, positive tests of tuberculosis infection(T-SPOT), an increased lactate dehydrogenase(LDH)level in CSF, basilar meningeal enhancement, and tuberculosis infection outside the central nervous system were the influencing factors of the PR(all P<0.05). Multivariate analysis showed that limb paralysis, cranial nerve palsy, an increased CSF-LDH level, and positive T-SPOT were independent risk factors of PR(all P<0.05). PR was not associated with prognosis( P=0.165). Conclusions:PR occurs in 35.6% of children with TBM.Limb paralysis, cranial nerve palsy, an increased CSF-LDH level and positive T-SPOT are independent risk factors of PR.PR does not adversely affect the outcome.Identifying PR is extremely important for the prevention of some clinical misunderstandings.

To identify the cause of an outbreak of acute hemorrhagic conjunctivitis (AHC) in Jiangxi (China) in 2010, 20 eye conjunctival swabs were first collected from AHC patients. Then, viruses were isola- ted and tested for human enterovirus 70, coxsackievirus A24 variant (CV-A24v) and adenovirus using the polymerase chain reaction. All CV-A24v isolates underwent sequencing of 3C and VP1 coding regions. Then, a phylogenetic tree was constructed for Jiangxi CV-A24v and worldwide CV-A24v based on,3C and VP1 regions, respectively. Ten out of 20 specimens were positive for CV-A24v, implying that the outbreak was caused by CV-A24v. The phylogenetic tree based on the 3C region showed that Jiangxi CV- A24v belonged to cluster 5 in genotype IV (GIV-C5) with strains isolated throughout the world after 2010, and were divided further into A and B lineages. Phylogenetic analyses of the VP1 region showed that all of the worldwide CV-A24v strains isolated after 2000 could be divided into five groups (1-5). Jiangxi CV-A24v was classified into group 5 and also divided further into A and B lineages upon analyses of the 3C region. These data suggested that CV-A24v causing AHC outbreaks in China in 2010 belonged to GIV-C3 and GIV-C5. At least two transmission lineages were circulated in Jiangxi in 2010. The classification of CV-A24v isolated after 2010 worldwide using the phylogenetic tree based on the VP1 region was almost consistent with that based on the 3C region and also had significant chronological clustering.

OBJECTIVETo report the experiences of the diagnosis and treatment of primary lymphoma of the small intestine (PSIL).

METHODSThe clinical data of 15 patients with PSIL treated from January 2003 to July 2007 was investigated retrospectively. Of the 15 cases, 9 patients were male and 6 were female, the average age was 51.6 years (range, 18 - 73 years). Data of gender, age, clinical manifestation, laboratory examination, imageology examination, diagnosis and treatment of the patients was reviewed.

RESULTSThe most common clinical manifestations were as follow: abdominal pain, abdominal lump, bowel obstruction, gastrointestinal hemorrhage and athrepsy. Serum tumor markers were checked normal. All the 15 cases were found with tumor by spiral CT, and 12 cases were diagnosed as PSIL. Eleven cases were given Ba-meal examinations, and positive results was found in 4 cases, and only 1 case was considered to be PSIL. All the 15 patients received operation. All the patients were diagnosed as non-Hodgkin lymphoma (NHL) by postoperative pathology (8 patients as diffuse large B-cell lymphoma, 5 as mucosa associated lymphoid tissue type B cell lymphoma and 2 as enteropathy-type intestinal T cell lymphoma). No perioperative death occurred. Ten patients received adjuvant chemotherapy with the regimen of CHOP (cyclophosphamide + epirubicin + vincristine + prednisone) after the operation. Fourteen cases were followed-up for a mean time of 30 months (range, 6 - 52 months). The 1- and 3-years survival rate was 85.7% and 57.1%, respectively.

CONCLUSIONSPSIL has no specific clinical manifestations, the diagnostic rate with barium study is low, spiral CT scan is a promising diagnostic method for PSIL. Operation combined with chemotherapy is important for PSIL.

Objective To explore whether brachial-ankle pulse wave velocity (baPWV) can be used as a predictor of recurrent cardiovascular events in elderly male patients with acute coronary syndrome (ACS). Methods The baPWV and biochemical indicators were measured in 118 elderly men with ACS, aged 61-92 years (mean age 76.6±6.7 years). During the follow-up period (617±297 days), all cardiovascular events (unstable angina, heart failure, cardiac death and stroke, etc.)were recorded. Results The baPWV was (17.48±3.54)m/s in non-event group(n=90),(21.91±4.86) m/s in event group and (24.48±4.39) m/s in major endpoint event group, respectively (both P＜0. 05). There were 30 cardiovascular events that occurred in 28 patients, including 12 major endpoint events. The receiver operating characteristic curve demonstrated that the cut-off point of baPWV for predicting a cardiovascular event was 19.51 m/s and that for predicting a major endpoint event was 20.52m/s. The multivariate Cox proportional hazards model demonstrated that the above cut-off points had significantly relative risk for cardiovascular event: 1.37(95% CI: 1.16-1.63)and for major event:1.71(95% CI: 1.23-2.36). Conclusions The baPWV can be used as a predictor of recurrent cardiovascular events in elderly men with ACS.

ObjectiveTo investigate the status of benefit finding in diabetic patients,and mediating effect of resilience between family support and benefit finding in diabetic patients.MethodsFive hundred and thirteen diabetic patients from a hospital of Harbin were recruited as investigative subjects from September 2015 to June 2016.The resilience scale,family adaptability,cohesion scale and benefit finding scale were used in the study.ResultsThe scores of benefit finding,resilience and family adaptability and cohesion were 55.67±12.87,70.65±10.39 and 104.25±15.38,separately.The total score of family adaptability and cohesion was positively related to the total score of benefit finding(r=0.389,P<0.05).The total score of resilience was positively related to the total score of benefit finding(r=0.155,P<0.05).The total score of family adaptability and cohesion was positively related to the total score of resilience(r=0.112,P<0.05).Benefit finding as the dependent variable,the results of hierarchical regression analysis indicated that family adaptability and cohesion (β=0.382,P<0.01),resilience(β=0.098,P<0.01)entered the regression equation.There was a partial mediating effect of resilience between family support and benefit finding in diabetic patients.The mediating effect was 0.011,accounted for 2.8% of the total effect.The resilience was the important protective factor for benefit finding.ConclusionFamily support has a direct influence on benefit finding and an indirect effect mediated by resilience on benefit finding.

Objective To investigate the safety and effectiveness of ultrasound-guided paravertebral anaes-thesia combined with propofol in the thoracoscopic sympathectomy. Methods Total 63 male and 59 female patients with hyperhidrosis were recruited. The patients were equally divided into two groups:group A and C. Patients in group A received ultrasound-guided paravertebral anaesthesia combined with propofol. Patients in group C received general intravenous anesthesia with endotracheal intubation. The heart rate (HR),mean arterial pres-sure(MAP)and the oxygen saturation(SpO2)at the time of entering the operating room(T0),completing anesthe-sia(T1),incising the skin(T2),cutting the T4 sympathetic trunk(T3),completing the operation were record-ed. The awake time after operation ,VAS score after operation and postoperative throat discomfort were also record-ed. Results The two groups successfully completed the surgery. There were no significant differences of the HR , MAP and SpO2 at T0-T4 between the two groups. There were significant differences of the awake time after opera-tion,postoperative feeding time and hospitalization expenses. The VAS score after operation of group A were better than group C(P<0.05)at T2 h,T4 h,T8 h,and T12 h. There was no significant difference of VAS score at T24 h between the two groups. Conclusion Ultrasound-guided paravertebral anaesthesia combined with propofol can pro-vide a safe and effective approach for patients receiving the thoracoscopic sympathectomy.
