Objective To explore the value of combined application of qualitative detection of TB-DNA serum anti-PPD-IgG and acid-fast staining methods in the diagnosis of tuberculosis infection .Methods Totally 278 pulmonary tuberculosis patients and 121 non-pulmonary tuberculosis patients were collected from Qingyuan people′s hospital during the period from January 2013 to June 2015 .Tuberculosis in patients with TB-DNA qualitative and serum anti-PPD-IgG and acid-fast staining test results was analyzed . Sputum TB-DNA qualitative and serum anti-PPD-IgG detection and joint application of acid-fast staining in the diagnosis of tuber-culosis infection .Results Sensitivities of acid-fast staining ,TB-DNA and serum anti-PPD-IgG in the TB group were 32 .01% , 51 .44% and 48 .56% respectively .The detectable rate of combining TB-DNA with serum PPD-IgG was 67 .63% .The detectable rate of combining TB-DNA with acid-fast staining was 54 .68% .The detectable rate of combining serum anti-PPD-IgG with acid-fast combined rate was 57 .55% .The detectable rate of combining three assays improved to 68 .71% .Conclusion Serum anti-PPD-IgG detection in the diagnosis of tuberculosis is simple ,effective ,qualitative detection of acid-fast staining sensitivity better than TB-DNA ,but it had a poor specificity .Bacteriologic diagnosis are tuberculosis diagnostic gold standard,but the detectable rate for acid-fast bacilli is low .The qualitative of TB-DNA test had a better sensitivity and specificity than other two assay .Combining with three assays could increase detectable rate and improve diagnosis of tuberculosis disease .

3.Adult dermatomyositis with gastrointestinal bleeding and perforation:a case report and analysis of literature
Chinese Journal of Postgraduates of Medicine 2017;40(7):601-603
Objective To investigate the clinical features and prognosis of adult dermatomyositis with gastrointestinal bleeding and perforation. Methods The clinical data of a adult dermatomyositis with gastrointestinal bleeding and perforation were retrospectively analyzed. And the clinical characteristics of this patient were analyzed, combined with 7 cases reported in the literature. Results Among the 8 cases, 6 cases were females and 2 cases were males, aged 18 to 63 years. The 5 cases had melena, 3 cases had hematemesis, 3 cases had hematochezia and 1 case had hemoptysis. The main treatment was glucocorticoids, immunosuppressive agent, intravenous immune globulin (IVIG), endoscopic hemostasis and angiographic embolization. Four of the 8 cases died. Conclusions Adult dermatomyositis with gastrointestinal bleeding and perforation is rare, but the condition is dangerous and the mortality is high. Dermatomyositis with early onset of abdominal pain, vomiting, melena should be alert to serious complications such as gastrointestinal bleeding and perforation.
7.Research progress on correlation between subclinical hypothyroidism and cardiovascular diseases
Tianjin Medical Journal 2016;44(4):509-512
Subclinical hypothyroidism is a metabolic disease, defined by increased thyroid-stimulating hormone (TSH) and accompanied by normal thyroid hormone levels. Recent years, many domestic and foreign studies have showed that sub?clinical hypothyroidism may be related with atherosclerosis and left ventricular diastolic dysfunction, which increasing the risk and mortality of cardiovascular diseases. Subclinical hypothyroidism may be associated with lipid metabolic disorders, hypertension, coagulation dysfunction, endothelial dysfunction, abnormal glucose metabolism, homocysteine, C-reactive pro?tein and lipoprotein. At present, controversy persists on the subclinical hypothyroidism. The aim of this study is to review the correlation between cardiovascular diseases and subclinical hypothyroidism.
8.Polymorph transformation of solid drugs.
Acta Pharmaceutica Sinica 2015;50(5):521-7
For the minimized phase transtorming risk, the most stable polymorph is generally considered as the desirable solid form for pharmaceutical applications. However, occasionally, the stable form may have some shortcomings such as low solubility, dissolution rate and bioavailability, etc. In that case, the metastable form which is kinetically stable at room or lower temperature could be selected. Using metastable form may result in polymorph transformation in pharmaceutical manufacture and storage. Hence, the knowledge of the transformation between solid forms is essential to the development of the drug materials. In this paper, we will review the recent studies in the area of crystal conversion of polymorphs and hydrates, to illustrate some cases to introduce the types, conditions and mechanisms of the crystalline solid transformation.
9.Effects of Morphine on μOpioid Receptor-mediated ERK Phosphorylation
Herald of Medicine 2014;(11):1446-1449
Objective To study the phosphorylation mode of extracellular regulated kinase( ERK)induced by acute and chronic morphine treatment on Chinese hamster ovary( CHO)cells expressed withμopioid receptors. Methods The time course of ERK phosphorylation 1 h and 36 h after morphine exposure as well as naloxone-precipitated withdrawal was detected by immunobloting. Results A transient enhancement of ERK phosphorylation was induced by 1 μmol · L-1 morphine with the peak effect at 5 min(P〈0. 01),and the effect was dose-dependent. No difference in ERK phosphorylation was found after 36h of treatment with 10 μmol · L-1 morphine compared with the control. However,5 or 10 min-naloxone precipitation induced remarkable decrease in ERK phosphorylation compared with the control(P〈0. 01). Conclusion Different changes of ERK phosphorylation were found under acute and chronic morphine treatment and naloxone precipitation,indicating a compensation of ERK related pathway induced byμ opioid receptors.
10.Epidemiological investigation on human coronovirus infection in hospitalized children with lower respiratory tract infection in Shanghai
Chinese Journal of Infectious Diseases 2015;(5):281-285
Objective To investigate the epidemiological and clinical characteristics of human coronovirus (HCoV ) infection in hospitalized children with acute lower respiratory tract infection (ALRTI)in Shanghai.Methods A retrospective cohort study was conducted between October 2009 and September 2012.Five hundred and fifty-four cases of ALRTI in children under 5 years were enrolled. HCoV and other respiratory viruses in archival nasopharyngeal aspirate specimens were detected by a commercial Seeplex RV12 ACE detection kit.HCoV pan-family reverse transcription polymerase chain reaction (PCR)was performed to screen all known six HCoV,including HCoV-229E,HCoV-OC43, severe acute respiratory syndrome (SARS)-CoV,HCoV-NL63,HCoV-HKU1 ,and real-time PCR was performed to screen Middle East respiratory syndrome (MERS)-CoV.MEGA5 .0 software was used to perform sequence alignment and phylogenetic tree analysis.Results In 554 samples,at least one virus was identified in 273 cases (48.56%)and HCoV was detected in 18 cases (3.25 %),among which 13 were HCoV-OC43/HKU1 positive,5 HCoV-229E/NL63 positive.No high pathogenic MERS-CoV and SARS-CoV were detected.The median age of 18 children with HCoV infection was 18 months (1 -48 months)with 12 boys and 6 girls.Seventeen cases had fever,11 cough,9 tachypenea and 1 wheeze. Seven received oxygen therapy,and 6 were admitted to intensive care unit for treatment.Two who was in ordinary ward were coinfected with adenovirus and human rhinovirus.All 18 cases recovered or improved on discharge.Six was infected in autumn,5 in winter,3 in spring and 4 in summer.Of 8 HCoV-positive samples which were sequenced,each 3 samples belonged to HKU1 and 229E subtypes,respectively,and each 1 belonged to OC43 and NL63 subtypes,respectively.Conclusions HCoV is a relatively common viral pathogen among hospitalized young children with ALRTI in Shanghai.No high pathogenic MERS-CoV is detected.HCoV can cause severe infection with favorable outcome.
