Objective To evaluate the protective effect of polysaccharide nucleic acid fraction of bacillus Calmette-Guerin (BCG-PSN) against atopic dermatitis (AD) in Nc/Nga mice,and to explore its possible mechanism.Methods Sixteen Nc/Nga mice were classified into normal control group (n =4),low-concentration BCG-PSN group (n=5) and high-concentration BCG-PSN group (n =7) to be subcutaneously injected with sodium chloride physiological solution,BCG-PSN of 0.1 mg/kg and 0.5 mg/kg respectively,at 1,8,15 and 22 days of age.Dinitrochlorobenzene (DNCB) was repeatedly and topically applied to these Nc/Nga mice to induce AD-like lesions at 49 days of age.The preventive effect of BCG-PSN against AD was evaluated by dermatitis scores,scratching frequency,histopathological manifestations and immunological parameters (including IgE,i nterleukin (IL)-4 and-12,and interferon (IFN)-γ).Results Repeated injection of BCG-PSN within 4 weeks after birth significantly decreased the severity of DNCB-induced AD-like lesions,dermatitis scores and scratching behavior in Nc/Nga mice.There was no statistical difference in scratching frequency between the high-and low-concentration BCG-PSN groups.BCG-PSN treatment reduced the plasma level of IgE in Nc/Nga mice in a dose-dependent manner.BCG-PSN at 0.5 mg/kg increased the number of cells secreting IFN-γ in skin lesions of mice.Both doses of BCG-PSN down-regulated IL-4 level,but up-regulated IL-12 level in the culture supernatant of spleen mononuclear cells from mice.Conclusion Early injection of BCG-PSN could protect Nc/Nga mice against dermatitis by promoting the proliferation of IFN-γ-secreting cells,increasing the synthesis of IL-12,and reducing the levels of IL-4 and IgE.

Objective To analyze recent 30 years’ regularities in point selection for acupuncture treatment of Parkinson disease and provide reference for its treatment. Methods Parkinson disease, parkinsonism and acupuncture were used as key words. Recent 30 years’ Chinese literature was searched using Wanfang, CNKI, VIP and Chinese biomedical literature database. Selection of main acupoints and scalp acupuncture points, syndrome differentiation-based point selection and meridian tropism of main acupoints were metrologically studied. Results The Du meridian, the large intestine meridian and the gallbladder meridian were mainly selected for acupuncture treatment of Parkinson disease. Taichong(LR3), Baihui(GV20), Hegu(LI4) and Fengchi(GB20) were used as main points. Chorea-tremor control area, motor area and parietotemporal anterior oblique line were often selected as main scalp acupuncture points. Fenglong (ST40), Qihai(CV6), Sanyinjiao(SP6), Yinlingquan(SP9) and Zusanli(ST36) were often used according to syndrome differentiation-based point selection. Conclusion Modern acupuncture doctors select Taichong(LR3), Baihui(GV20), Hegu(LI4) and Fengchi(GB20) as main points, often use scalp acupuncture points and combine points mainly from the Du meridian according to syndrome differentiation in the treatment of Parkinson disease.

Objective: To evaluate the feasibility ofin vitro balloon dilatation for treating aortic coarctation infants younger than 6 months. Methods: A total of 13 aortic coarctation infants treated in our hospital from 2011-01 to 2015-12 were summarized. The patients were at the mean age of 3.4 months (from 20 days to 6 months), with the mean body weight of 4.8 kg (from 3.6 kg to 6.2 kg) including 9 male. Aortic coarctation segments were resected during the operation and the resected segments were expanded by percutaneous transluminal angioplasty (PTA) via (2-4) times diameter balloon dilatation. The diameters of resected aortic segments were recorded before and after expansion; the change of vascular middle smooth muscle layer was observed by HE staining. Results: There were 8 cases with non-restricted ventricular septal defect (VSD) and 3 of them received staging operation, 2 with atrial septal defect (ASD), 3 with bicuspid aortic valve, 3 with patent ductus arteriosus (PDA) and 1 with pericardial effusion. The resected aortic segments presented that 9 patients had diaphragm type narrow and 4 had tube type narrow. After PTA, the diameters of resected aortic segments were slightly increased for the mean of 0.2 mm and no obvious change was observed; HE staining showed that the vascular inner mucosa was shed, while the middle smooth muscle layer was intact. Conclusion: Balloon dilatation had the poor effect for treating aortic coarctation infants younger than 6 months; surgical procedure could be applied for treating the relevant patients.
