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.Advances in protective effects of thyroid hormone on myocardial mitochondria by sirtuins
Tianjin Medical Journal 2017;45(1):108-112
Many studies have confirmed that thyroid hormone (TH) and mitochondria have protective effects on myocardium. The partial subtype of sirtuins (SIRTs) can also be able to protect myocardium by mitochondria, which includes improving ischemia reperfusion injury, improving the pathological cardiac hypertrophy and improvement of heart failure. SIRTs can achieve the protective effect for myocardium mainly through inhibiting mitochondrial permeability transition pore and mitochondrial membrane permeabilization, maintaining balance of regulation of mitochondrial morphology, promoting mitochondrial biogenesis, maintaining the function of autophagy of impaired mitochondria. At the same time, there is an interaction between TH and SIRTs. At present, the role of mitochondria has become more and more concerned in apoptosis and necrosis and its protective effect on cells. This review summarized the protective effect of SIRTs on myocardium through mitochondrial and the influence of the interaction between SIRTs and TH on myocardial protection of mitochondrial.
8.Dendritic cells differentiated from 129/svj ES-D3 embryonic stem cells prolong syngeneic neural progenitor cells survival in ischemic rat brain
Chinese Journal of Immunology 2015;(3):318-322,328
Objective:To study if embryonic stem cell derived dendritic cells(esDCs) could induce transplant tolerance to syngeneic neural progenitor cells ( NPCs) in ischemic rat brain.Methods:Neural progenitor cells ( NPCs) were differentiated from 129/svj pCX-eGFP ES-D3 embryonic stem cells and dendritic cells were directly differentiated from 129/svj ES-D3 respectively.All of SD rats were accepted MCAo surgery and subdivided in two groups based on pretreatment with or without esDCs through tail vein injection 1 week after MCAo.pCX-eGFP NPCs were then injected into the lateral ventricle of animals 2 weeks after MCAo.A proliferation assay of lymphocytes dissociated from cervical lymph nodes by MTT method,counting of the survival of the grafted cells, histological evaluation of CD4,CD8 and ED1 positive cells in brain and detection of mRNA level of IL-10 and IFN-γin ischemic lesions by reverse transcriptase-polymerase chain reaction(RT-PCR) were performed 2 weeks after graft (4 weeks after MCAo).Results:Pre-treatment with esDCs decreased CD4 positive cells infiltration (134.7 ±36.2 vs.198.8 ±59.6,P<0.05) and enhance the survival of NPCs in ischemic striatum,but had no effect on ED1 (298.8 ±75.9 vs.302.2±88.5),CD8 positive cells (145.8 ±45.4 vs.134.3 ± 39.0) distribution (P>0.05).There was also no difference in lymphocytes proliferation (PI,1.245 ±0.211 vs.1.331 ±0.235) or mRNA expression level of IL-10 ( 1.147 ±0.260 vs.1.264 ±0.119 ) and IFN-γ( 1.697 ±0.273 vs.1.829 ±0.250 ) between two groups ( P>0.05).Conclusion:The results indicate that pretreatment with esDCs may prolong syngeneic NPCs survival though reducing CD4 positive cells reaction in ischemic striatum,which provides some evidence for the tolerogenic function of esDCs.However,there was lack of evidence for cytokine-dependent routine involving in this mode and further investigation was needed to make certain the cardinal principle.
9.Diagnosis and treatment of Budd-Chiari syndrome (clinical analysis of 46 cases)
Clinical Medicine of China 2001;17(3):185-
Objective To explore the measure to diminish the misdiagnosis of Budd-Chiari syndrome.Methods 46 cases of Budd-Chiari syndrome were analyzed.Results 33 cases had ever been misdiagnosed with average time of 5.3 years.One of the main clinical symptoms was the pathological process of lower limb(84.8%).Doppler color flow imaging examination showed positive rate of 100% in liver veins and inferior vena cava,,but none of the misdiagnosed cases received this examination.The viral marker test had a positive rate of only 4.3% that was not higher than that of general population.Conclusion Budd-Chiari syndrome has a variety of symptoms,so Doppler color flow imaging is considered an important means to diagnose this disease.
10.Clinical Intervention of Septic Myocardial Injury with Xuebijing Injection
Journal of Guangzhou University of Traditional Chinese Medicine 2014;(5):712-715,719
Objective To observe the clinical efficacy of Xuebijing injection ( XI) for the treatment of septic myocardial injury, and to study the possible therapeutic mechanism. Methods Thirty-nine qualified septic myocardial injury patients were randomly divided into XI group (N=24) and control group (N=15) . Both groups were treated with conventional therapy, including anti-inflammation treatment, transfusion for resuscitation, nutritional support, symptomatic and supportive treatment, and supportive treatment for keeping vital organ function. XI group was given intravenous drip of XI based on the conventional therapy. Before and after treatment, the peripheral blood concentrations of myocardial-specific isoenzyme of creatine kinase (CK-MB), cardiac troponin I (cTnI), brain natriuretic peptide ( BNP) and plasma calcitonin ( PCT) were detected, and the changes of electro-cardiogram ( ECG) were also observed. The mortality within 28 days was compared between XI group and the control group. Results ( 1) After treatment, cTnI, BNP and PCT concentrations in XI group were decreased significantly as compared with the control group, and there was statistical significance (P <0.05) . However, the decrease of CK-MB was not obvious in XI group ( P>0.05 compared with the control group) . ( 2) The difference of ECG was insignificant between the two groups after treatment ( P>0.05) . ( 3) The 28-day mortality was 8.33% in XI group, and was 13.33% in the control group, the difference being insignificant between the two groups (P>0.05) . (4) During the treatment, none case had adverse reaction. Conclusion XI can improve the myocardial injury, and relieve inflammation of septic myocardial injury patients.
