Based on recent cellular architectural studies on the bed nuclei of the stria terminalis (BST) in the rat by Ju et al, we studied vasoactive intestinal polypeptidelike immunoreactivity (VIP-LI) in the BST using PAP and ABC techniques. (1) Compared with VIP-LI cells, the VIP-LI terminals were more abundant and concentrated. At the periphery of the oval nucleus and in the juxtacapsular nucleus, there was a dense accumulation of VIP-LI terminals. Less densely innervated areas were the part above the anterior commissure in the anterior lateral area and the central part of oval nucleus. The fusiform nucleus and rostral part of the anterior ventral area contained moderate amount of VIP-LI terminals. The principal nucleus, interfasicular nucleus, posterior dorsal nucleus and dorsal nucleus, were devoid of VIP immunoreactivity. VIP-LI fiber branches were sometimes seen going along the vessels in the BST. (2) VIP-LI cells were usually distributed in areas where the terminals were relatively sparse. In the central part of the oval nucleus, the VIP-LI cells were most concentrated, though the total number of it was less than that in the caudal part of the anterior dosal area, They were usually small fusiform in shape, however some were trangular or multipolar.

Objective　To investigate the relationship between the apnea events and the correspondent sleep stage. Methods 68 normal volunteers were studied with polysomnography to confirm the sleep stage of the apnea events. Results Sleep apnea events were found in each different sleep stage. The events happened frequently in light sleep stage, most in stage 2. There were no significant sleep stage distribution difference in different sex .The number and severity of apnea events were also not relative with the sleep stage distribution. Conclusion Apnea events happened most frequently in light sleep stage. The reason is still unclear.

Objective To evaluate the clinical efficacy ofZi Wu Liu Zhu Na Jia needling (acupuncture based on midnight-noon ebb-flow theory) in treating spastic hemiplegia after cerebral stroke by using surface electromyography (sEMG).Method Fifty-two patients with spastic hemiplegia due to cerebral stroke were randomized into a treatment group and a control group, 26 cases each. The two groups were both intervened by conventional rehabilitation training. In addition, the treatment group was givenZi Wu Liu Zhu Na Jia needling and the control group was given ordinary acupuncture. The two groups were treated once a day, 15 sessions as a course. The ambulation ability, muscle tension, neurological deficit score (NDS), Fugl-Meyer Assessment Scale (FMA), and Berg Balance Scale (BBS) were evaluated before the intervention and after 2 treatment courses, and the sEMG signals were also collected and analyzed.Result The Holden's Functional Ambulation Classification (FAC) and Modified Ashworth Scale scores were significantly changed in the two groups after the intervention (P<0.01). After the intervention, the FAC and MAS scores in the treatment group were significantly different from those in the control group (P<0.05). The NDS, FMA and BBS scores were significantly changed in the two groups after the treatment (P<0.05). The NDS, FMA and BBS scores in the treatment group were significantly different from those in the control group after the treatment (P<0.05). Of the sEMG signals, H/M max in the treatment group was significantly different from that in the control group after the intervention (P<0.01).Zi Wu Liu Zhu Na Jia needling with rehabilitation training can significantly mitigate the muscle tension and promote the activities of daily living in patients with spastic hemiplegia after cerebral stroke.

Lung transplantation is the only effective treatment of most end-stage lung diseases. Airway anastomotic complications are the main obstacles affecting the postoperative survival and quality of life of lung transplant recipients. Airway anastomotic stenosis is the most common airway anastomotic complication after lung transplantation. In recent years, improvements in the recipient selection, organ preservation, surgical techniques, postoperative intensive care management, immunosuppression, antifungal and endoscopic treatment have decreased the incidence of airway anastomotic stenosis and improved the surgical efficacy of lung transplantation and the survival of the recipients. In this article, the pathogenesis, risk factors, diagnosis and treatment of airway anastomotic stenosis after lung transplantation were reviewed, aiming to provide novel ideas for clinical research, diagnosis and treatment of airway anastomotic stenosis following lung transplantation.

Objective To study the action of kaempferol (KAE) against Candida albicans biofilms and explore the potential mechanisms. Methods Biofilm metabolic activity assay was used to investigate the action of KAE against C. albicans biofilm formation as well as mature biofilm. The inhibition of KAE in hyphal formation was examined by microscope. The water-hydrocarbon two-phase separation assay was used to test the effect of KAE on the cell surface hydrophobicity of C. albicans. The mRNA expression of the genes involved in biofilm formation was determined by real time RT-PCR. Results KAE showed inhibition effect on C. albicans biofilm formation in a dose-dependent manner. Moreover, KAE inhibited mature biofilm. The biomass of biofilm was reduced upon KAE treatment. KAE inhibited hyphal formation and reduced the cell surface hydrophobicity of C. albicans. In the presence of KAE, the mRNA expression of the genes involved in biofilm formation was changed, with the up-regulation of BCR1,NRG1,TUP1 and down-regulation of HWP1,EFG1,CPH1,ALS1,ALS3 and CSH1. Conclusion KAE showed antifungal activity against C. albicans biofilm. The mechanisms may relate to the inhibition of hyphal formation and reduction of cell surface hydrophobicity.
