Relationship between intestinal microflora imbalance and nonalcoholic fatty liver disease / 临床肝胆病杂志

The intestinal microecosystem is composed of natural microflora, intestinal epithelial cells, and intestinal mucosal immune system. Nonalcoholic fatty liver disease (NAFLD) is a metabolic stress-induced liver injury associated with insulin resistance and genetic susceptibility. In recent years, there has been increasing evidence showing the involvement of imbalanced intestinal microflora in the pathogenesis of NAFLD. Overgrowth of intestinal microflora, increased permeability of intestinal mucosa, intestinal endotoxemia, and production of inflammatory cytokines play important roles in the development of NAFLD. Further studies on the relationship between intestinal microflora imbalance and the pathogenesis of NAFLD may shed light on the treatment and prevention of NAFLD.

The impact of psychological intervention of the five-emotion restrictive therapy on coronary heart disease / 国际中医中药杂志

Objective To observe the impact of the five-emotion restrictive therapy on coronary heart disease. Methods109 hospitalized patients with coronary heart disease were randomly divided into a experimental of 56 patients and a control group of 53 patients according to length of stay. The control group was treated with the conventional therapy; the experimental group was imposed five-emotion restrictive psychological intervention on the basis of conventional therapy. The investigation was done using self-rating anxiety scale(SAS) and self-rating depression scale(SDS) on 1 day after admission and ld before discharge respectively. SAS and SDS scores were surveyed. At the same time Holter monitoring and normal ECG test were compared. Results Compared with control group, the experimental group 1 d before discharge of the SAS and SDS scores were (41.9±7.4) and (38.6±8.4), and the difference was statistically significant (P＜0.01) . The total effective rate of Holter monitoring and normal ECG was 64.15％ and 92.85％ in the control and experimental group, and the difference was significant (P＜0.01) . ConclusionThe pathological seven emotions have a certain affection on the incidence of coronary heart disease, treatment and prognosis of the course. Five-emotion restrictive psychological intervention can adjust timely psychological state of patients, eliminate negative emotions, and significantly help the incidence, treatment and prognosis of the disease.

Development of a diagnosis model for active pulmonary tuberculosis using mass spectrometry and pro-tein chip / 中华微生物学和免疫学杂志

Objective To develop a diagnosis model for active pulmonary tuberculosis. Methods The proteomic fingerprinting of 264 sera from active tuberculosis patients and controls were analyzed using the surface-enhanced laser desorption ionization time of flight mass spectrometry (SELDI-TOF-MS) and protein-chip technology. The peaks were detected and filtrated by Ciphergen PrnteinChip(R) Software (version 3.1.1). Using the Biomarker Pattern 5.0 software, a diagnostic model was developed for diagnosis of active tuberculosis. Re-sults Fifty protein peaks were significantly different between the patients with active pulmonary tuberculosis and the controls with overlapping clinical features (P<0.01). Five protein peaks at 4360, 3311, 8160, 5723, 15173 m/z were chosen for the system classifier and the development of diagnosis model 1. The model differenti-ated the patients with active pulmonary tuberculosis from the controls with a sensitivity of 83.0%, and a speci-ficity of 89.6%. The diagnostic accuracy was up to 86.4%. Three protein peaks at 5643, 4486, 4360 m/z were chosen for the system classifier and the development of diagnosis model 2. The model differentiated the pa-tients with active pulmonary tuberculosis from the controls with a sensitivity of 96.9%, and a specificity of 97.8%. The diagnostic accuracy was up to 97.3%. Conclusion It might be a new diagnostic test for the de-tection of sera from the patients with active pulmonary tuberculosis using SELDI-TOF-MS and protein chip.

Prenatal Gene Diagnosis for High Risk Infant of Thalassemia / 中华围产医学杂志

Objective To evaluate the value of prenatal gene diagnosis for thalassemia. Methods 128 fetuses suspected with thalassemia were performed amniocentesis or cordocentesis for gene diagnosis. Results No severe complications occurred during all procedures. 32 fetuses had normal genotype. 38 were heterozygous and 27 were homozygous of ?- thalassemia; 18 were heterozygous, 4 were homozygous and 9 were double heterozygous of ?-thalassemia. The types and frequencis of ?-thalassemia mutation were CD 41-42(47.5%), IVS-Ⅱ-654(42.5%), 17(A-T)(7.5%) and -28 (A-G)(2.5%) in turn. Pregnancies of 40 fetuses with severe thalassemia were terminated in time. Conclusions The screening and prenatal diagnosis of high risk fetus for thalassemia is safe, effective and accurate. It should be used as an obstetrical routine examination at the region with high thalassemia occurrence.
