ObjectivesTo study the treatment timing and method of glucocorticoids in the treatment of abdominal type Henoch-Sch?nlein purpura (HSP).MethodsA total of 201 children with abdominal type HSP hospitalized from September 2009 to April 2013 received either conventional glucocorticoids treatment or rapid titration treatment of glucocorticoids based on the same basic therapy. According to the treatment timing and method of glucocorticoids, all patients were divided into 4 groups including early convention group (n=46), late convention group (n=44), early titration group (n=56) and late titration group (n=55). The duration from the appearance of gastrointestinal symptoms to using glucocorticoids less than or equal to three days was deifned as early treatment and more than three days was deifned as late treatment. The patients in two convention groups (early and late) were treated with methylprednisolone (2-6mg/kg per day).The patients in two titration groups (early and late) received rapid titration of methylprednisolone from an initial low dose of 2mg/kg per day to the ifnal target dose. The gastrointestinal symptoms were evaluated every 12 hours. If the gastrointestinal symptoms were not alleviated, an additional dosage of methyl-prednisolone was given. On the next day, the total dose of methylprednisolone in previous 24 hours was used as the initial dose. The dosage was increased in such a way till the gastrointestinal symptoms disappeared and this dosage was remained for 3 days. Then the dosage was gradually reduced to the maintenance dose and stopped. If the gastrointestinal symptoms were relapsed, the patients were treated again. A follow-up of 3-6 months was performed. The dosage, recurrence of symptoms and the side effects were compared among four groups.ResultsThe time of remission, target dose of glucocorticoids, total dose of glucocorticoids, recurrence rate, incidence of severe symptoms and Henoch-Schonlein purpura nephritis were signiifcantly different among four groups (P<0.05). The curative effect was best in early titration group and worst in late convention group.ConclusionsIn the treatment of abdominal type HSP, early titration treatment with glucocorticoids can signiifcantly relieve the gastrointestinal symp-toms and reduce the total dosage of glucocorticoids.

Objective To explore the relationship between depression and malnutrition in hospitalized aged patients. Methods The mini nutritional assessment (MNA) table and geriatric depression scale (GDS) were used to investigate the nutritional status and depression of 114hospitalized elderly. Results The prevalence of depression was 62.3% (71 patients), the prevalences of malnutrition and latent malnutrition were 43.9% (50 patients) and 41.2% (47patients) respectively. The prevalence of malnutrition and latent malnutrition was higher in depressive patients than in non-depressive patients. After controlling age, number of illnesses, bed-ridden or not and method of nutrition, the nutritional status was negatively correlated with the grade of depression.Conclusions The prevalence of malnutrition in depressive patients is high and is associated with the grade of depression.

This study examined the impacts of intrauterine murine cytomegalovirus (MCMV) infection on the long-term learning and memory of offspring. Sexually matured male and female BALB/C mice without MCMV infection were identified by ELISA and then mated. Seventy pregnant mice were randomly divided into the virus group (n=40) and the control group (n=30), in which the pregnant mice were subjected to placenta inoculation of MCMV suspension (1 μL, 1×106 PFU) or the same amount of cell culture medium, respectively, at gestational age of 12.5 days. Some pregnant mice [virus group (n=20), control group (n=15)] were sacrificed by cervical dislocation at gestational age of 18.5 days, and the head circumference and brain weight of the mouse fetuses were measured, and the MCMV infection in their brain tissues was detected by PCR. The other pregnant mice [virus group (n=20), control group (n=15)] delivered naturally, and the learning and memory capability of the offspring at 70-day-old was analyzed by Morris water maze test. The results showed that 28.57% mouse fetuses in the virus group developed viral infection in the brain. Their head circumference and brain weight were significantly reduced as compared with those in the control group (P<0.01). The Morris water maze test revealed that the mouse offspring in the control group found the platform with straight-line trajectories after training. In contrast, the counterparts in the virus group intended to enter the central area, but looked for the platform with a circular trajectory. And the infected mice exhibited prolonged swimming distance and swimming latency (P<0.01). It was concluded that: (1) placenta inoculation of MCMV can cause fetal brain infection and intrauterine development retardation; (2) the offspring of MCMV placenta inoculation mice showed a long-term decline in learning and memory capability.

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.

Human trophoblast cells were isolated and cultured in vitro in order to investigate possible pathogenesis of intrauterine infection caused by HCMV. Trophoblast cells were obtained by compound enzymes digestion and discontinuous percoll gradient. Cells and purity were identified by using immunocytochemistry assay with anti-CK7, Vim and beta-hCG antibodies. HCMV AD169 strain replication in isolated trophoblast cells and cell apoptosis were detected at different time points post infection (p.i.). The results showed that highly purified trophoblast cells were obtained. Specific virus replication was increased dramatically at the 24th h p.i., and then increased slowly during 48 h and 72 h. Apoptosis rate of trophoblast cells infected with HCMV was (34.68+/-3.14)% at 24th h p.i., while that in control group was (15.32+/-2.34)% (P<0.05). It was suggested that highly purified trophoblast cells can be isolated by the simplified cell purification method. HCMV can infect human trophoblast cells, and be quickly replicated, resulting in the accelerated apoptosis of human trophoblast cells during early time.

Objective To study the correlations between DLN and clinical pathological factors and provide clinical data for assessing the operation scopes and prognostic evaluations aims at further clarify its clinical values.Methods The research aimed at the 69 cases who undertook first-time surgery and confirmed thyroid papillary carcinoma by intraoperative frozen pathology from 2013 to 2014 in Wannan Medical college affiliated Yijishan Hospital.The groups was divided by whether the DLN had been detected and metastasized.And we made chi-square test or t test by using SPSS 22.0 to analysis between the clinical and pathological factors.Results The groups was divided by whether DLN had been metastasized from the detected cases and the results shown that there was no relationship with gender,age,tumor size,Hashimoto's thyroiditis and the number of COLN (which not including DLN).For multifocal cases (21.05％ vs 57.14％,P =0.047);for vascular infiltration,the positive cases of (10.53％ vs 71.43％,P＜0.001);for the metastasized rate of COLN,the positive cases of (65.79％ vs 14.29％,P =0.011);for the metastasized number of COLN,[(0.84 ± 1.48) vs (3.86 ± 3.08),P ＜ 0.001].All the data above illustrated that the two groups are statistically correlative in mulifocality,vascular infiltration,the metastasized rate of COLN and for the metastasized number of COLN.17.39％ of PTC cases can be detected by CD34 and D2-40.According to the presence of vascular infiltration,it can be divided into two groups,We contrast analyzed of the number of TCLN (include DLN),metastasized number of TCLN and the metastasized rate of TCLN.The results shown that the number of TCLN had no statistical differences,but significant in metastasized number of TCLN [(0.74 ± 1.83) vs (4.50 ± 2.20),P ＜ 0.001) and the metastasized rate of TCLN (29.82％ vs 100.00％,P ＜ 0.01)].Conclusions The DLN positive patients are more likely to have distant lymph node metastasized.If DLN positive,total thyroidectomy and bilateral central compartment neck dissection (CCND) has been necessary.Lateral selective neck node dissection (LSND) can be underwent after evaluating carefully combining with the history and preoperative images.CD34 and D2-40 could be the detection indexes of vascular infiltration for PTC.For the cases with vascular infiltration,it has a higher proportion to have the metastasized number and metastasized rate of TCLN and higher possibility of distant metastasis.So we should expand the scope of operation moderately and strengthen postoperative follow-up according to the history and preoperative images so as to reduce postoperative recurrence,distant metastasis rate and improve the living quality of patients.
