This study was conducted to investigate the physicochemical properties of Polyporus umbellatus sclerotial exudate. Morphological characteristics of the sclerotia and its exudate were observed during different stages of sclerotial formation. The pH of the exudate was detected at different time during cultivation. A phenol-sulfuric acid method was employed to determine the polysaccharide content of P. umbellatus sclerotial exudate during cultivating time. Additionally, the protein content was measured by means of BCA protein assay. Furthermore, CAT content was detected using ultraviolet absorption method. That the protein content of the exudate and CAT specific activity rose gradually during the passage of the cultivating time indicated a high level of oxidative stress during P. umbellatus sclerotial exudate formation. The results showed that the pH of the exudate increased gradually and then dropped down during sclerotial formation. That the pH of the exudate maintained the acidity state during the cultivation indirectly indicated that acidic environment would help sclerotial formation. The exudate produced gradually and was absorbed by the sclerotia itself.

Obstructive sleep apnea syndrome (OSAS) is an independent risk factor for atherosclerosis. Accumulated evidence has revealed that OSAS can induce systemic inflammation, oxidative stress, and endothelial dysfunction, which will contribute to the pathogenesis of atherosclerosis. T lymphocytes can be activated by inflammation and oxidative stress, resulting in the elevated cytotoxicity towards vascular endothelial cells. Thus, T lymphocytes play a key role in OSAS-related atherosclerosis development or progression via immuno-inflammatory alterations. This review described the current development of the role of T lymphocytes in OSAS-related atherosclerosis.

AIM: To assess the changes of macular thickness of acquire immunodeficiency syndrome ( AIDS) patients.
METHODS:The study based on the data analysis of 38 human immunodeficiency virus ( HIV ) positive patients ( 64 eyes ) . According to CD4 count and whether cytomegalovirus retinitis ( CMVR) happened, the patients were divided into 3 groups. Group A included 16 patients (32 eyes), in which CD4 count was < 50cells/μL and CMVR did not happen. Group B included 10 patients ( 20 eyes), in which CD4 count was>50cells/μL and CMVR did not happen. Group C included 12 patients (12 eyes), in which CD4 count was < 50cells/μL and CMVR just happened. Group D included 10 healthy people ( 20 eyes ) , as normal control group. By using optical coherence tomography ( OCT ) , thickness of retina along with a 1mm diameter circle centered on macular was evaluated.
RESULTS:The mean foveal thicknesses in groups A, B, C and D were 254. 03±15. 63μm, 263. 11±17. 12μm, 304. 50±50. 62μm and 257. 64±8. 54μm in order. Compared with foveal thickness in each group, there were significant differences in general (F=12. 933, P=0. 000). The mean foveal thickness in groups CMVR increased, which was of significant difference (P= 0. 000), compared with other groups.
CONCLUSION: CMVR can impair the structure and function of macular, which then seriously affects the visual function of patients. It's helpful to understand the progress and prognosis of CMVR disease by observing macular structure with OCT in early time.

Objective To explore the clinical features and endoscopic manifestations of eosinophilic gastroente-ritis(EG)in children.Methods A retrospective analysis was conducted of the clinical manifestation,laboratory examination,endoscopy(upper and/or colonoscopy)performance,diagnosis and treatment of 49 cases of patients who were diagnosed as EG in Children's Hospital of Nanjing Medical University from July 2013 to July 2015.Results The common clinical manifestations of EG in children were hematochezia(23 cases),diarrhea(20 cases),vomiting(18 cases)and abdominal pain(15 cases).The ages of children admitted to hospital for the first time ranged from 1 month and 7 days old to 13 years and 7 months old,and the mean age was 59.4 months old,in which most patients were younger than 1 year old,accounting for 38.77％(19 cases)of all.Peripheral blood eosinophilia was present in 20 cases(40.82％)of the patients,and only 6/18 cases(33.33％)of the patients had elevated serum IgE.Upon endoscopic analysis,the lesions involved esophagus(4 cases),stomach(14 cases),duodenum(20 cases),small intestine(15 cases),colon(28 cases)and rectum(6 cases),and the most common manifestation under gastroscopy was mucosal hyperemia edema(27 cases)and erosion(9 cases),while the most common manifestation under colonoscopy was mucosal hyperemia edema(25 cases)and nodular hyperplasia(24 cases).All patients improved with food restriction,in which 8 cases were treated with glucocorticoid while 9 cases with oral Singulair and 9 cases with oral Loratadine.All children with symptoms were alleviated somewhat,but 5 cases of them relapsed after drug withdrawal.Conclusions The clinical manifestations of EG in children varied and were mainly hematochezia,vomiting,diarrhea and abdominal pain.Some patients had the elevated peripheral blood eosinophilia and serum IgE.The most common manifestations under gastroscopy were mucosal hyperemia edema and erosion while the most common manifestations under colonoscopy were mucosal hyperemia edema and nodular hyperplasia.

ObjectiveTo investigate the effects of acupuncture on the serum leptin and IGF-1 in patients with post-stroke depression (PSD).MethodsBy using Hamilton rating scale for depression (HAMD),94 patients with PSD were recruited and randomly divided into 2 groups:acupuncture group and control group.All patients were given routine clinical treatments and second level medical prevention.Patients in the acupuncture group received Linggui Ba fa acupuncture treatment and oral administration of Sertraline and patients in the control group were treated with oral administration of Sertraline only.Serum levels of letpin and insulin growth factor (IGF-1) were measured by enzyme linked immunosorbent assay (ELISA) before and after treatments in all patients.ResultsThe levels of leptin and IGF-1 in patients of acupuncture group were significantly lower than that of the control group after treatment[(17.06 ± 12.38) ng/ml vs (32.27 ± 15.09)ng/ml,P＜0.01; (52.61±24.74)ng/ml vs (77.15±20.83)ng/ml,P＜0.01 respectively].The scores of HAMD in acupuncture group were significantly lower than that of control group after the treatment[(8.06±3.32)、(13.67±8.05)]and 6 month later[(6.52±2.08)、(10.26±6.16)].ConclusionThe serum levels ofleptin and IGF-1 were significantly lower and depression symptoms were improved after acupuncture in elderly patients with post-strok depressin.

Objective To explore the role of CD 30 on CD4 + T lymphocyte and T lymphocyte subset activation in asthma pathogenesis.Methods Twenty seven asthma active attack patients,16 acute upper respiratory infection patients and 19 control children were randomly selected. Direct immunofluorescence flow cytometry was used to detect the CD 30 positive percentage on CD4 +cell; ELISA was used to detect the levels of interleukin(IL) 4 and IL 13 in culture supernatants of peripheral blood mononuclear cells(PBMC) and plasma total immunoglobulin E(IgE) level.Results Compared with control group and acute upper respiratory infection group, in asthmatic children the CD4 +CD 30 + percentage on CD4 + cell was elevated significantly; 2.The levels of IL 4 and IL 13 in supernatants of cultured lymphocyte were increased significantly, the plasma total IgE level was increased significantly;3.There was a significant positive correlation of CD4 +CD 30 + cell percentage with the levels of IL 4 and IL 13 in culture supernatants and plasma total IgE.Conclusions The cell that could produce Th2 derived cytokine may consist of CD 30 +cell;When CD 30 L combined with CD 30 on CD4 + cells ,it might result in Th2 cell proliferation ,develop and release Th2 derived cytokine; IL 4 and IL 13 could induce B cell production and secrete more IgE. It is suggested that CD 30 and imbalance of Th2 subset may play an important role in asthma pathogenesis.

To study photosynthetic characteristics and its influencing factors in leaves of medicinal plant Mirabilis himalaica, and provide an evidence for guiding artificial planting and improving the quantity. The light-response and diurnal photosynthesis course of leaves at the booting stages of 1-3 year old M. himalaica were measured with LI-6400 system. The Results showed that the light response curves were fitted well by non rectangle hyperbola equation (R2 > or = 0.98). The values of the maximum photosynthetic rate (Pmax) and light use efficiency of three-year old M. himalaica leaves were higher than those of 1-2 year old individuals. The diurnal variation of net photosynthetic rate (Pn) and stomatal conductance (Gs) of 2-3 year old M. himalaica were typical double-peak curves determinately regulated by stomatal conductance. However, transpiration rate (Tr) of 1-3 year old plants leaves were single-peak curve, which was self-protection of harm reduction caused by the higher temperature at noontime. Correlation analysis showed that the changes between photosynthetic active radiation (PFD), air temperature (T ) and Pn, were significant positive related. Therefore, M. himalaica is a typical sun plant, which should be planted under the sufficient sunshine field and prolong the growing ages suitably in order to improve the yield.
