Objective To study the value of fluorescence quantitative polymerase chain reaction (FQ-PCR) detection in early skin tissue fluid of syphilis.Methods A total of 40 patients of suspected syphilis who received therapy from September 2014 to September 2016 in our hospital were selected in this study.Five mL venous blood samples were collected in all the patients,and detected by toluidine red unheated serum test (TRUST) and treponema pallidum antibody enzyme-linked immunosorbent assay (ELISA),and skin tissue fluid were collected and performed FQ-PCR detection,all patients were treated with benzylpenicillin for 3 and 6 months,then detected again,the conversion rates were record.Results There was no significant difference in the detection rate of ELISA and FQ-PCR[97.50%(39/40) vs.95.00%(38/40),P>0.05].The total detection rate of ELISA and FQ-PCR were significantly higher than that of TRUST[97.50%(39/40) vs.67.50%(27/40),95.00%(38/40) vs.67.50%(27/40),P<0.05].After 3 and 6 months of treatment,negative rates of ELISA and FQ-PCR were significantly higher than that of TRUST(P<0.05),there was no significant difference on negative rate between FQ-PCR and ELISA (P>0.05).In the FQ-PCR detection results,the average value of TP-DNA was significantly decreased after treatment,there were significant differences in the phase Ⅰ,phase Ⅱ compared with before treatment(P<0.05).Conclusion FQ-PCR could be used to measure treponema pallidum (TP-DNA) effectively in early stage,it′s conducive to the diagnosis of syphilis,the clinical application value is high.

OBJECTIVE:Analyze drug use of pediatrics in China,and to provide reference for promoting research,develop-ment and supply of pediatric drugs. METHODS:Analyze the data of drug use in 2 632 514 pediatric patients aged from 0 to 14 of 78 sample hospitals from Beijing,Shanghai,Tianjin,Hangzhou,Zhengzhou,Guangzhou and Chengdu in“The Hospital Prescriptions Cooperation Project”of Hospital Pharmacy Professional Committee of Chinese Pharmaceutical Association,statistical analysis was performed by using Excel and Access software. RESULTS:Pediatric patients in 78 sample hospitals of 7 regions had used 1 572 kinds of drugs from 2013 to 2014,but only 31.04%of drugs were pediatric drugs;both the ratio of pediatric drug types and the ra-tio of pediatric drugs use frequency had a great gap in different drug classifications. The ratio of drug use frequency in injection ad-ministration was 57.97%,and it was greatly higher than that of oral administration(31.04%). Among oral solid preparations,the ratio of drug use frequency for drugs with unreasonable specification was 29.57%,and ratio of drug types was 40.99%. CONCLU-SIONS:The pediatric patients had a great drug shortage in kinds,dosage forms and specifications in 78 sample hospitals of 7 re-gions during 2013-2014. Off-label drug use,high frequence of injection use,tablets used after breaking and other irrational phenom-ena were found in pediatric patients during clinical drug therapy,which reduced high risk of drug use. It is recommended that gov-ernment should strengthen and improve incentives mechanism of research,development and supply of pediatric drugs,so as to solve pediatric drug shortage in China,promote rational clinical drug therapy for children and guarantee the safety of drug use in pe-diatrics.

OBJECTIVE:To provide reference for the promotion of rational use of essential medicines and further implementa-tion of essential medicines system. METHODS:Depended on the data (including the number of species,the amount of prescrip-tion and prescription departments,etc)of essential medicines(chemical drugs and biological drugs)use in outpatient and emergen-cy departments and wards of 20 sample medical and health institutions fromThe Hospital Prescriptions Cooperation Project,statis-tical analysis was performed by using Excel and Access software. RESULTS:The proportion of the amount of essential medicines included in National Essential Medicines List(2012 edition)or Beijing Essential Medicines(Supplementary list)(2012 edition)to the amount of total medicines(hereinafter referred to as the essential medicines use ratio)in medical and health institutions of Bei-jing from 2013 to the first half year of 2014 was small and showed a slight downward trend. The essential medicines use ratio of grade 2 and grade 3 general hospitals did not reached the required ratio by former Health Department. The essential medicines use ratio in different departments showed great differences,the essential medicines use ratio in imaging department was 100%,while chemotherapy departnent was 4.04%. The essential medicines use ratio in different medicines also showed great differences,5 kinds of drugs(including sulfani lamides)was 100%,while there were 16 kinds of drugs that was less than 0.1%. CONCLUSIONS:The essential medicines use ratio is relatively low in medical and health institutions of Beijing from 2013 to the first half year of 2014 and shows great differences in different departments and different medicines. It is suggested to further improve the essential medi-cines use ratio to better benefit the majority of patients by changing the prescribing habits of physicians,strengthening the advocacy of essential medicines policy and optimizing the use of essential medicines in different departments.

Objective To investigate the diagnostic value of color Doppler ultrasonography in congenital muscular torticollis (CMT). Methods The sonographic characteristics of 62 children with CMT confirmed clinically were retrospectively analyzed. Results Abnormal ultrasound features could be visualized in all of 62 children with CMT. According to the sonogram features, 62 children were divided into 2 types: mass-forming (32/62, 51.61%) and diffuse type (30/62, 48.39%). Arterial flow signals were detected in 18 children (18/62, 29.03%); RI was 0.73-0.88. Conclusion Ultrasonography has specific value for the diagnosis of CMT.

Objective To observe the effect of the health education and skills training for caregivers on health status of stroke patients and their family caregivers. Methods Hospitalized stroke patients were divided into the intervention group (n=38) and the control group (n= 36). Both groups received rehabilitation training for 1 month in hospital. The family caregivers of intervention group received Timing It Right education and skills training in addition. All the patients were assessed with the European Stroke Scale (ESS), Mini-Mental State Examination (MMSE), simple Fugl-Meyer Assessment (FMA), modified Barthel Index (MBI), and the caregivers were assessed with the General Health Questionnaire (GHQ-12) before and 3 months after intervention. Results The scores of ESS, FMA, MBI improved more in intervention group than in the control group after intervention (P<0.05), as well as their caregivers in the items of playing a useful part, under stress, overcoming difficulties, enjoying normal activities, facing up to problems, feeling unhappy and depressed, lossing confidence, thinking of self as worth of GHQ-12 (P<0.05). Conclusion Health education and skills training for family caregivers can improve the health of caregivers, and further improve the function outcome of stroke patients.

Objective To investigate the effect of carbachol on local gut inflammation during entetal resuscitation of rats with bum shock. Method Thirty-eight Wistar rats were subjected to 35%TBSA full thickness scald injury, and enteral fluid was infused into animal intestines via duodenal stomas 30 minutes post bum. The animals were randomly divided into four groups: no resuscitation (Control, n = 8), enteral resuscitation using either a glucose electrolyte solution (GES, n = 10) or GES plus carbachol (60 μg·kg-1,GES/CAR, n = 10), or carbachol alone (CAR, n = 10) .The volumeof GES infusion was based on the Parkland formula (4 ml· 1% TB-SA-1·Kg-1) - All animals were sacrificed 4 hours post bum, and specimens of jejunal tissue were collected to determine the levels of tumor necrosis factor (TNF)-α, nitric oxide (NO), nitric oxide synthase (NOS) and myeloperoxidase (MPO). Serum assays for plasma diamine oxidase (DAO) activities were also performed. Results There were no statistical differences in the intestinal levels of NOS, NO, TNF-α and MPO, and plasma OAO activities, between the GES group and the control group. Compared to the GES group, the GES/CAR group showed significantly lowered levels of intestinal NOS (1.276 ±0.391 vs. 1.818 ±0.436, P＜0.05), NO (0.925 ±0.402 vs. 1.561 ±0.190, P ＜ 0.05, TNF-α (0.87±0.13 vs. 1.94±0.47, P ＜0.01) and MPO (0.465 ±0.092 vs. 0.832±0.214, P＜0.05),and reduction in plasma DAO activites (0.732±0.192 vs. 1.381 ±0.564, P ＜0.05). The CAR group also showed significantly lowered levels of intestinal NOS, NO, TNF-α and MPO and reduced plasma DAO activites, compared to the GES group. Conclusions Theses results suggest that carbachol significantly inhibits the release of proinflammatory mediator and attenuates local inflammation in gut during enteral fluid resuscitation of rats in rats with bum shock. We postulate that carbachol may exert its and-inflammatory effects via the cholinergic anti-inflammatory pathway.

This paper is to explore changes of intestinal mucosal barrier, intestinal flora, and bacterial translocation in rats with severe acute pancreatitis (SAP). Twenty four male SD rats were randomly divided into the control group (n = 10) and the experimental group (n = 14). The model of severe acute pancreatitis of rats was induced by the method of injecting adversely 5% sodium taurocholate into the common biliary-pancreatic duct. All of the rats were killed after 24 hours and the level of the serum amylase and the plasma endotoxin was determined after that. The pathological changes of pancreas and small intestine were observed through hematoxylin-eosin staining (HE staining) and the abdominal viscera bacterial translocation rates were tested. With the method of real-time polymerase chain reaction (RT-PCR) the quantity of the intestinal flora was analyzed. In the control group, the level of Escherichia coli, Lactobacillus and Bifidobacterium were 2.08 ± 1.29, 11.04 ± 7.55 and 12.21 ± 4.95, respectively. On the contrast, the level of Escherichia coli in the cecum contents was much higher (9.72 ± 3.58, P < 0.01), while the Lactobacillus number was decreased significantly (0.67 ± 0.34, P < 0.01), and the Bifidobacterium number was also decreased (4.59 ± 3.42, P < 0.05) in the experimental group, so the ratio of Bifidobacterium/Escherichia coli was reversed. Besides, in the experimental group, the plasma endotoxin positive rates and the bacterial translocation rates were much higher (P < 0.01 or P < 0.05) and the pathology scores of pancreas and small intestines were also significantly higher (P < 0.01) than those in the control group. These results indicated that in severe acute pancreatitis rats, the intestinal mucosal barrier was severely damaged and the dysbacteriosis occurs in the intestinal canal. And these might relate to the occurrence and development of multiple organ infection.

Objective To investigate the correlation between plasma cystatin C (CysC) level and carotid atherosclerotic plaque in patients with ischemic stroke.Methods The clinical data in patients with acute ischemic stroke were analyzed retrospectively.According to the results of carotid artery ultrasound,the patients were divided into either a non-plaque group or a plaque group.Then the plaque group was redivided into a stable plaque subgroup and a vulnerable plaque subgroup.Multivariate logistic regression analysis and Pearson correlation analysis were used to explore the risk factors for carotid atherosclerotic plaque.Results A total of 226 patients with acute ischemic stroke were enrolled,172 of them had carotid plaque,and 54 had no plaque.Of the patients with carotid plaque,94 were stable plaque and 78 were vulnerable plaque.The age (71.82 ± 9.94 years vs.60.74 ± 13.81 years; t =6.160,P =0.014),proportion of patients with ischemic heart disease (11.6％ vs.1.9％; x2=6.169,P=0.020),systolic blood pressure (148.770± 21.007 mm Hg vs.142.240 ± 19.404 mm Hg; t =2.029,t =0.044),plasma CysC concentration (1.046 ± 0.438 mg/L vs.0.860 ±0.214 mg/L; t =3.006,P =0.003),and carotid IMT (1.122 ±0.278 mm vs.0.878 ±0.250 mm; t =5.762,P=0.000) in the plaque group were significantly higher than those in the non-plaque group.Multivariate logistic regression analysis showed that the age (odds ratio [OR] 1.079,95％ confidence interval [CI] 1.044-1.116; P=0.000) and IMT (OR 31.450,95％ CI 6.233-158.692; P=0.000) was the independent risk factor for carotid plaque,while there was no significant independent correlation between the plasma CysC level and carotid plaque (P =0.217).Only IMT in the stable plaque subgroup was significantly higher than the vulnerable plaque group (1.176 ±0.285 mm vs.1.058 ±0.258 mm; t =-2.824,P =0.005),and it was the independent protective factor for the carotid plaque stability (OR 0.195,95％ CI 0.059-0.064; P =0.007).Pearson correlation analysis showed that the plasma CysC level was positively correlated with the age (r =0.375,P =0.000) and serum creatinine level (r =0.462,P =0.000),but it was not significantly correlated with carotid IMT (r =0.075,P =0.264).Conclusions In patients with ischemic stroke,no correlations were found between the plasma CysC level and carotid atherosclerotic plaque,plaque stability,and IMT.

Objective To evaluate the feasibility of CEUS in Crohn discasc (CD) activity.Methods Thirty-nine patients with CD were analyzed.The clinical disease activity index of 18 cases were less than 150 (inactivity),and 21 cases were between 150 and 450 (activity).The thickness of intestinal walls were measured and Limberg classification were determined by power-Doppler results.The CEUS was performed,and the parameters including rise time,peak intensity,mean transit time,time from peak to one half,wash in slope and time to peak were statistical analyzed.Results The thickness of the lesions,peak intensity and wash in slope of activity CD were greater than those of inactivity CD,which had significant difference (all P＜0.05).The Limberg classification of type Ⅰ was 1 case,type Ⅱ was 4 cases,type Ⅲ was 10 cases and type Ⅳ was 6 cases in activity CD.The Limberg classification of type Ⅰ was 10 cases,type Ⅱ was 7 cases and type Ⅲ was 1 case.The Limberg classification were mainly type Ⅲ and type Ⅳ in activity CD,and type Ⅰ and type Ⅱ in inactivity CD,which had significant difference (P＜0.001).Conclusion CEUS can provide quantitative parameters in CD activity and has great clinical value.

Objective To investigate the predictive factors affecting the efficacy of cyclophosphamide (CTX) combined with glucocorticoids in the treatment of idiopathic membranous nephropathy (IMN),and to evaluate the efficacy of calcineurin inhibitor (CNI) adjustment due to poor treatment.Methods A retrospective cohort study was conducted.Two hundreds and twenty-eight patients with IMN diagnosed by renal biopsy in the People's Hospital of Guangxi Zhuang Autonomous Region from January 1,2007 to December 1,2016 were enrolled.All subjects were treated with CTX in combination with glucocorticoids.The patients were divided into two groups:remission group and no remission group.Multivariable logistic regression analysis was used to determine the baseline clinical-pathological influencing factors for the remission of IMN in the enrolled patients.Results The number of total remission (including complete and partial remission) of the first CTX combined with glucocorticoid treatment in 228 patients with IMN was 188(82.5％).Among them,141 patients (61.8％) had complete remission (CR),the median time for CR was 8(6,12) months,and the median time for partial remission (PR) was 3(1,4) months.The median follow-up time for this study was 25(13,43) months.Compared with the remission group,the serum albumin level was lower in the non-remission group,the 24-hour urine protein content,the blood complement C3 and C4 levels were higher,and the pathological stage was milder (all P ＜ 0.05).Multivariate logistic regression analysis suggested that the levels of baseline serum albumin,complement C4,and pathological stage were independent predictors of clinical remission in IMN patients.Twenty-four non-remission patients were treated with CNI.The overall response rate was 66.7％(16/24) at 6 months and 77.3％(17/22) at 12 months.Conclusions The levels of baseline albumin,blood complement C4,and pathological stage were independent predictors of clinical remission in IMN patients treated with CTX plus glucocorticoids.The non-remission patients with CTX combined with glucocorticoid therapy can still achieve a higher response rate after adjusting for CNI.
