Objective To evaluate the clinical efficacy of acupuncture plus auricular point electroacupuncture and its effect on the quality of life (QOL).Method Ninety-eight patients with post-stroke depression were randomized into a treatment group and a control group, 49 cases in each group. The treatment group was intervened by acupuncture plus auricular point electroacupuncture, while the control group was by oral administration of Fluoxetine hydrochloride. The Hamilton Depression Scale (HAMD), Side-effect Rating Scale (SERS), and the World Health Organization Quality of Life Questionnaire-Brief Version (WHOQOL-BREF) were observed before and after intervention, and the clinical efficacies were also compared.Result The total effective rate was 89.1% in the treatment group versus 87.0% in the control group, and the between-group difference was statistically insignificant (P>0.05). Respectively after 2-week, 4-week, and 8-week treatment, the HAMD scores were significantly different from that before intervention in the treatment group (P<0.05). Respectively after 2-week, 4-week, and 8-week treatment, the HAMD scores were significantly different from that before intervention in the control group (P<0.05). There were no significant differences in comparing the HAMD scores between the two groups after 2-week, 4-week, and 8-week treatment (P>0.05). The SERS scores in the treatment group were significantly different from that in the control group after 4-week and 8-week treatment (P<0.05). In the treatment group, the SERS score after 8-week treatment was significantly different from that after 4-week treatment (P<0.05). After treatment, the scores of general health domain 1 and 4, physical health domain, psychological health domain, and environment domain from WHOQOL-BREF were significantly changed in both groups (P<0.05). After intervention, the physical health domain score of the treatment group was significantly different from that of the control group (P<0.05).Conclusion Acupuncture plus auricular point electroacupuncture is an effective approach in treating post-stroke depression, and it can improve the quality of life of the patients.

Objective:To investigate the effect of Budesonide (BUD) on pulmonary vascular development and the expression of vascular endothelial growth factor (VEGF) and nucleotide binding oligomerization domain-like receptor protein 3 (NLRP3) in newborn rats with bronchopulmonary dysplasia (BPD) caused by intrauterine infection.Methods:The 15-day-pregnant SD rats were divided into control group and infection group [intraperitoneal injection of 0.35 mg/(kg·d) lipopolysaccharide], and the newborn rats born by the above groups were divided into 3 groups: BUD group (0.5 mg of BUD suspension), normal control group (NC group, equal amount of 9 g/L saline), BPD group (equal amount of 9 g/L saline), with 40 rats in each group, all of them were inhaled twice a day for 14 days.Ten newborn rats were selected at birth, on the 3 rd, 7 th and 14 th day after administration.Pulmonary histopathological changes and radial alveolar counts (RAC) were observed after HE staining, and the thickness of alveolar respiratory membrane was measured; the platelet-endothelial cell adhesion molecule (PECAM-1/CD 31) in lung tissue was detected by immunohistochemistry, and the density of pulmonary microvessels was calculated; the expressions of VEGF, NLRP3 and Caspase-1 were detected by Western blot; and the levels of serum interleukin( IL)-1β and IL-18 were measured by enzyme-linked immunosorbent assay. Results:With the increase of day-old, the lung tissue of newborn rats in NC group was gradually developed and matured, the structure of alveoli was clear, the size was uniform, the count was significantly increased, and no obvious pathological changes were observed.In BPD group, the lung tissue structure was disordered, the alveoli were different in size and few in count, and inflammatory cells were exuded from the alveoli or the alveoli space.Compared with BPD group, the pathological changes of lung tissue in BUD group were significantly reduced.On the 3 rd, 7 th and 14 th day after administration, compared with NC group, the RAC, average integral optical density of CD 31 positive cells, density of pulmonary microvessel and level of VEGF protein in lung tissue of BPD group and BUD group were lower, and the differences were statistically significant (all P<0.05); while the thickness of respiratory membrane, level of NLRP3, Caspase-1 proteins in lung tissue and serum levels of IL-1β, IL-18 were significantly higher, and the differences were statistically significant(all P<0.05). Compared with BPD group, the RAC, average integral optical density of CD 31 positive cells, density of pulmonary microvessel and level of VEGF protein in lung tissue of BPD group and BUD group were significantly higher, and the differences were statistically significant (all P<0.05); while the thickness of respiratory membrane, level of NLRP3, Caspase-1 proteins in lung tissue and serum levels of IL-1β, IL-18 were significantly lower, and the differences were statistically significant (all P<0.05). Conclusions:The occurrence and development of pathological changes of BPD newborn rats caused by intrauterine infection can affect the development of pulmonary vessels through the inflammatory response of lung tissue.BUD can alleviate pathological changes in lung tissues of BPD newborn rats by reducing inflammatory reaction and up-regulating VEGF expression, promoting pulmonary vascular remodeling, and increasing pulmonary microvascular density.

Wnt signaling is implicated in the control of cell growth and differentiation during neural stem cell(CNS) development.Wnt3a, one of wnt gene family members, has effect on regeneration neurospheres and differentiation into neurons.Wnt3a inhibits regeneration of neurospheres, and promotes its differentiation. In vitro neurosphere was cultured in a serum-free defined medium DMEM/F12 supplemented with bFGF and EGF. Dissociated cells were plated onto poly-d-lysine-coated coverslips and propagated in medium containing recombined Wnt3a-adenovirus. Plenty of Nurr1 were detected by RT-PCR after 3 days. Wnt3a combined AA would improve NSC differentiation into dopaminergic (DA) neuron. The quantity of DA neuron is obviously more than the AA alone group's. Moreover, the expression of TH mRNA is 1.86 fold in Wnt3a combined AA group. Induced cells were immunostained for TH and DAT. The proportion of TH-positive was (37.42 ? 2.54) % (P

Objective To study the clinical and pathological features of histiocytic necmtizing lym-phadenitis( HNL) in children. Methods The clinical data and histological findings of 38 cases of HNL admitted in our hospital from June 2000 to May 2015 were reviewed. Results Most of the patients were school-age children with male-femal ratio of 1. 4: 1. The main clinical features were lymphadenopathy (100%),fever(68. 24%),leucocytopenia(52. 63%),rising of lymphocytes percentage(84. 21%). All of the lymph node excisional biopsy met the criterion of HNL. Some cases spontaneously relieved and some cases were treated with NSAID,glucocorticoid or immunoglobulin and benefited significantly. There was no recurrence. Conclusion The clinical situation is not specific. The diagnosis is established by lymph node ex-cisional biopsy. HNL is benign and self-limited disease. The effect of management using glucocorticoid, NSAID and immunoglobulin is remarkable. Long term follow-up is necessary.
