ObjectiveTo observe the effects of fire-needle of Lingnan on the vitiligo model after hydroquinone-induced oxidative stress based on the Hippo-YAP signaling pathway. MethodsC57BL/6 mice were randomly divided into normal group （Control）， model group （HQ）， HQ+fire-needle group （FA）， and positive control group （Halometasone）， with 8 mice in each group. The vitiligo model was prepared by hydroquinone （HQ）. The skin pathological changes were observed by depigmentation score， HE staining and Masson-Fontana. Elisa was used to detect the levels of tyrosinase （TYR）， malondialdehyde （MDA） and monoamine oxidase （MAO）.Western-blot and PCR were used to detect the expression of Yap1 and Tp73 among the groups. ResultsCompared with the control group， the epidermis and dermis were significantly thicker. The number of melanocyte hair follicles， basal melanocytes， epidermal cells containing melanin granules were significantly decreased， and the depigmentation score was significantly reduced（P＜0.01）. The level of TYR decreased， and the levels of MDA and MAO increased after modeling（P＜0.01）. The expression of Yap1 and Tp73 were significantly reduced （P<0.01）. The dermis became thinner in the halometasone and FA group after treatment of 4 weeks. The number of melanocyte hair follicles， basal melanocytes， epidermal cells containing melanin granules increased （P<0.05）. Compared with that of the HQ group， the level of TYR in the halometasone group and FA group was significantly increased （P<0.01）. The levels of MDA and MAO in the FA group were decreased （P<0.05）. The expressions of Yap1 and Tp73 in the FA group were significantly increased （P<0.01）， and their effects were better than those in the Halometasone group （P<0.05）. ConclusionsFire-needle of Lingnan protects melanocytes from oxidative stress by activating the Hippo-YAP pathway. It enhances the synthesis and function of melanocytes and promotes repigmentation by reducing the content and activity of oxidative stress products.

Professor LIN Guo-hua's clinical experience in staging treatment for post-stroke dysphagia / 中国针灸

The paper summarizes professor LIN Guo-hua's clinical experience in staging treatment for post-stroke dysphagia. Professor LIN Guo-hua adheres to "essence and marrow deficiency and primary yang decline" as the pathogenesis and "conducting yin from yang " as the treating principle. By regulating the conception vessel and the governor vessel and focusing on yang meridians, in association with meridian differentiation and the location differentiation, professor LIN provides the staging treatment for post-stroke dysphagia. At the oral phase, yangming is dysfunction, manifested as facial paralysis and flaccid tongue. In treatment, reducing method is predominated at yangming meridian specially. At the pharyngeal phase, shaoyang is invaded by pathogens, manifested as pivoting dysfunction. The treatment focuses on communicating the exterior with the interior and promoting shaoyang meridian. At the esophageal phase, yangming meridian is deficiency and the turbid qi fails to descend, thus the reinforcing method is dominated to promote and tonify yangming. Additionally, the kinesiotherapy of acupuncture is assisted and the Lingnan fire needling therapy is used particularly. All of the summaries above provide the reference for the clinical treatment of post-stroke dysphagia.

Influence of fire needle stimulation at Sihua acupoints on performance status and Th1/Th2 ba-lance in the patients with advanced non-small cell lung cancer after chemotherapy / 针刺研究

OBJECTIVE: To observe the influence of fire needle stimulation at Sihua acupoints combined with chemotherapy on Th1/Th2 imbalance and performance status in the patients with advanced non-small cell lung cancer (NSCLC) so as to investigate its immunological mechanism underlying the improvement of lung cancer. METHODS: Sixty eligible NSCLC inpatients were randomly assigned to a control group and a treatment group (n＝30 cases in each one). The control group was treated with paclitaxel combined with cisplatin (TP) or gemcitabine plus cisplatin (GP) of chemotherapy, and the treatment group was treated with fire needle stimulation at Sihua acupoints (i.e. bilateral Geshu [BL17] and Danshu [BL19]) and with chemotherapy simultaneously. The fire needle stimulation was given once daily for successive 7 days. One day before and 14 days after chemotherapy, the patients' blood samples were collected for assaying the concentrations of Th1 related cytokines (IL-2, IFN-γ) and Th2 related cytokines (IL-4, IL-10) with ELISA. The Karnofsky performance status (KPS) score was used to assess the patient's physical conditions before and 14 days after chemotherapy. RESULTS: Compared with the results before treatment, the levels of IL-2 and IFN-γ concentration increased obviously and the levels of IL-4 and IL-10 concentration as well as KPS score decreased significantly in the treatment group and the control group after treatment (all P<0.01). After treatment, compared with the control group, the levels of IL-2 and IFN-γ concentration in the treatment group increased and the levels of IL-4 and IL-10 concentration decreased (P<0.01); and the decrease amplitude of KPS score in the treatment group was less than that in the control group (P<0.01). CONCLUSION: Fire needle stimulation at Sihua acupoints improves the function of Th1 cells, and reduces the function of Th2 cells. As a result, the balance between Th1 and Th2 has been modified and the deterioration degree of the performance status been alleviated in the patients after chemotherapy.

Nitric oxide mediates the inhibitory effects of interleukin-2 on the isolated ventricular papillary muscle and cultured neonatal rat cardiomyocyte / 浙江大学学报·医学版

OBJECTIVE: To explore the effects and mechanism of interleukin-2 on the isolated rat ventricular papillary muscle and cultured cardiomyocyte. METHODS: The isolated rat papillary muscle and cultured neonatal rat cardiomyocyte were used to determine the effects on contractile properties and spontaneous beating. RESULTS: IL-2 inhibited the contractile force of isolated rat papillary muscle and reduced the spontaneous beating rate of cultured neonatal rat cardiomyocytes in a dose-dependent manner. IL-2 at high concentration reduced the systolic duration and prolonged the diastolic duration. Pretreatment with L-NAME, an inhibitor of nitric oxide synthase,abolished the effects of IL-2. Heat inactivated IL-2 had no effect on papillary muscles and cardiomyocytes.CONCLUSION: Inhibitory effects of IL-2 on the contraction of isolated papillary muscle and spontaneous beating rate of cultured neonatal cardiomyocyte are mediated by nitric oxide.
