Objective To observe the effect of different methods such as combined treatment of traditional Chinese and western medi-cine, the simple excision and expanded resection for the treatment of granulomatous lobular mastitis. Methods 60 cases of patients treated in our hospital from Jan. 2010 to Jan. 2013 were enrolled in this study, and they were confirmed the diagnosis of granulomatous lobular mas-titis by pathology examination. According to randomly number table, they were divided into three groups and they were given the treatment of combined treatment of traditional Chinese medicine and Western medicine, the simple excision, and expanded resection respectively. Where-after, the therapeutic effect of the three groups were observed. Results There were 9 cases (45. 0%) were of cure and 11 cases (55. 0%) of recurrence in the combined treatment group. There were 16 cases (80. 0%) of cure and 4 cases (20. 0%) of recurrence in the simple ex-cision group. There were 8 cases (90. 0%) of cure and 2 cases (10. 0%) of recurrence in the combined treatment group. It shows that the recurrence rate of combined treatment group was higher than the other two groups (P<0. 05). The satisfactory rate of breast appearance after treatment were 17 (85%), 15 (75%) and 16 (80%) respctively, and there is no significant difference (P>0. 05). Conclusion The effect of extended resectionin for the treatment of granulomatous is better and it has important clinical value.

Objective To investigate the feasibility of a new polyclonal antibody specific to fetal hemoglobin (HbF) and its application in enrichment of circulating fetal nucleated red blood cell(NRBC) for non-invasive prenatal diagnosis. Methods A polyclonal antibody against a synthetic peptide comprising residues 69-78 of the γ-chain of HbF was prepared and conjugated to carrier protein KLH as the immunogen according to the specific antigenic determinant. The peptide-KLH solution was mixed with freund's complete or incomplete adjuvant and immunized goat to prepare specific polyclonal antibody against the γ-chain of fetal hemoglobin. After purification with protein G, maternal blood was obtained from 32 pregnant women at 22 to 39 weeks of gestation. NRBCs were separated and then stained with antibody against the γ chain of HbF. All the positive cells were collected by micromanipulator under microscopic observation, and whole genome was amplified by improved primer extension preamplification (PEP). Multiplex polymerase chain reaction amplification at nine different polymorphic short tandem repeat (STR) loci was also used to determine origin of the positive cells isolated from maternal blood. Results NRBCs stained with antibody against the γ chain of HbF were found in all of the blood from the 32 cases. Attached positive cells with anti-HbF staining have unique morphological characteristics, low nucleus-to-cytoplasm ratio, brown cytoplasm and blue dense nucleus after hematoxylin counterstain under microscopic observation, which can distinguished NRBCs with other cells. A total of 183 NRBCs were found in all of 32 pregnant women at a range of 0.6~1.8 cell/ml venous blood. The accurate rate was 90.6% by the STR genotype identification. Conclusion The antibodies specific to fetal γ-chain of fetal hemoglobin with synthetic peptide technology may have wide clinical utility in identification of fetal NRBCs from maternal circulation for non-invasive prenatal genetic diagnosis.

Objective To explore fecal bacteria transplantation for the treatment of severe gastrointestinal disease caused by food allergy. Method The therapeutic process of fecal bacteria transplantation for treatment of severe food allergy gastrointestinal disease was retrospectively analyzed, and the related literature was reviewed. Results A 2-year-old boy had onset of intestinal infection and diarrhea was persistent even though he had received adequate anti-infection therapy and supportive treatment. Finally, the patient received the treatment of fecal bacteria transplantation and the symptoms were then improved. No adverse reactions were observed in 2 months of follow-up. In foreign literature, fecal bacteria transplantation in children is mainly applied to clostridium difficile infection (CDI) and inflammatory bowel disease (IBD), with efficiency of 90%- 100% and 55.6% - 100%, respectively. While in the domestic literature, fecal bacteria transplantation in children is mainly used in CDI and antibiotic associated diarrhea, and the effective rate is 100%. No serious adverse reactions were found in all the researches. Conclusion Fecal transplantation is safe and effective in the treatment of children with severe gastrointestinal disease caused by food allergy, but its application in children is not yet mature and needs more in-depth researches.

AIM:To analyze the correlation between serum angiotensin-converting enzyme 2 (ACE2) levels and different stages of coronary heart disease (CHD), and to explore the change of serum ACE2 level during the development of CHD.METHODS:The control group included 85 non-CHD samples, and 174 CHD samples were divided into light stenosis (ls-CHD, stenosis degree <50%) group, moderate stenosis (ms-CHD, stenosis degree 50%~75%) group and severe stenosis (ss-CHD, stenosis degree ≥75%) group.The ACE2 level in each serum sample was detected by ELISA.The relationship between the ACE2 level and the development of coronary heart disease was explored by statistical analysis of serum ACE2 levels in different stages of CHD.RESULTS:The serum ACE2 levels in ls-CHD group, ms-CHD group and ss-CHD group were all higher than that in control group.The more severe the coronary artery stenosis existed, the higher the ACE2 level was observed.The serum ACE2 level in the males was higher than that in the females.In a single sex, the serum ACE2 levels in ls-CHD group, ms-CHD group and ss-CHD group were higher than that in control group with significant differences.Regression analysis found that sex, diabetes and CHD were associated with the serum ACE2 levels.Among them, sex and CHD were the independent factors to affect serum ACE2 levels.CONCLUSION:The serum ACE2 level of males was higher than that of females.Compared with the non-CHD samples, the serum ACE2 level of CHD patients was higher than that of the non-CHD samples.During the development of coronary heart disease, the serum ACE2 level increased constantly.

With the increasing prominence of population aging, the cognitive decline of the elderly has gradually become a hotspot of clinical research. As a traditional rehabilitation exercise, Tai Chi has been proved to have a positive effect on improving cognitive function and delaying cognitive decline in the elderly. However, the related brain function mechanism is still unclear. In this paper, we collected studies which observed the changes of Tai Chi on brain regions related to cognitive function in the elderly using magnetic resonance imaging (MRI), electroencephalogram (EEG) and functional near-infrared spectroscopy (fNIRS). We summarized relevant studies from perspective of structural and functional changes in the brain. The results showed that Tai Chi may delay and improve cognitive decline in the elderly by reshaping the structure and function of brain regions related to cognitive function such as memory, attention and execution. The effect of Tai Chi for cognitive function may be associated with positive regulation of cardiovascular function, emotion and meditation level of the elderly. In addition, the improvement of cognitive function further enhances the balance of the elderly. We also found that practice time, frequency and intensity of Tai Chi could be factors influencing the improvement of cognitive function and brain function in the elderly.
