OBJECTIVETo verify the clinical efficacy of acupuncture combined with auricle cutting method for treatment of blood stasis-type psoriasis.
METHODSFifty-six cases of blood stasis-type psoriasis were randomly divided into a combined therapy group, a auricle cutting group, an acupuncture group and a control group, 14 cases in each one. Based on regular treatment of TCM decoction in four groups, the combined therapy group was treated with acupuncture and auricle cutting method, and the auricle cutting group was treated with sham-acupuncture and auricle cutting, and the acupuncture group was treated with acupuncture and sham auricle cutting, and the control group was treated with sham-acupuncture and sham auricle cutting. The acupuncture was applied at Dazhui (GV 14), Feishu (BL 13), Ganshu (BL 18) and Geshu (BL 17), etc., and manipulated with routine technique; in the sham acupuncture, the needle was inserted into dermis layer so that the needles could be swung without being dropped out. In the auricle cutting, erbeixin (P1) of unilateral auricle was selected and cut by Chan needle to perform bloodletting; in the sham auricle cutting, the neighborhood approximately 0.5 cm next to erbeixin (P) of auricle was selected as cutting area. The treatment was given once a day, seven days as a treatment session for totally two sessions. Psoriasis area and severity index (PASI) before and after treatment was observed and efficacy of each group was compared.
RESULTSThe effective rate was 57.1% (8/14) in the combined therapy group, which was superior to 14.3% (2/14) in the auricle cutting group, 7.1% (1/14) in the acupuncture group and 0.0% (0/14) in the control group (all P < 0.05). The scores of PASI were all decreased in each group after the treatment (all P < 0.05), which was the most significant in the combined therapy group (all P < 0.05). After factorial analysis, the main effect was P < 0.05 in the auricle cutting, P < 0.05 in the acupuncture and P < 0.05 in interaction effect of combined therapy.
CONCLUSIONThe scores of PASI of blood stasis-type psoriasis could be effectively reduced by acupuncture, auricle cutting method and TCM decoction, among which the interaction effect of auricle cutting and acupuncture combined with TCM decoction is the most significant.

OBJECTIVETo retrospectively assess serious systemic adverse effects of standardized dust-mite vaccine in children with asthma.
METHODSMedical records of 704 children (5-17 years in age) with asthma between January, 2005 and December, 2011 were reviewed. Serious systemic adverse events following treatment with a standardized dust-mite vaccine in these children were analyzed.
RESULTSA total of 336 systemic adverse reactions were observed in 17.0% (120/704) of the patients analyzed of these adverse reactions, 18 (5.4%) were serious (level 3), 318 (94.6%) were not serious (below level 3), and no single case of anaphylactic shock (level 4) was recorded. Systemic adverse events occurred most frequently in the 5 to 11-year age group and in the summer season (from June to August). In the 18 severe cases, the peak expiratory flow (PEF) dropped by 20% immediately after the vaccine injection, and other major clinical symptoms included cough, wheezing and urticaria. All children with serious systemic adverse effects were given inhaled hormone and atomized short-acting beta agonists, oral antihistamines, intravenous dexamethasone and/or intramuscular adrenaline. After these treatments, the clinical symptoms were significantly relieved.
CONCLUSIONSThe rate of serious systemic adverse events following allergen-specific immunotherapy is relatively low in children with allergic asthma. Conventional medications are effective in managing these immunotherapy-associated adverse events.

BACKGROUND: All-trans retinoic acid (ATRA) is an ideal therapy for acute promyelocytic leukemia, which can induce promyelocytes to differentiate to mature granulocytes. However, differentiation syndrome is still a high risk for the patients undergoing ATRA therapy. Occurrence of this complication is closely related with cellular morphology change and expression and function of cellular adhesion molecules, especially selectin and integrin families. OBJECTIVE: To reveal rolling adhesion behavior and mechanical mechanism of ATRA treated HL-60 cells on the substrate coated with E-selectin under different fluid shear forces. METHODS: Using the equipment of parallel plate flow chamber, untreated and ATRA treated HL-60 cells were driven to roll on E-selectin-coated substrate. The mean rolling velocity and mean stop time were calculated. Here, the HL-60 cells were incubated in the medium containing 1×10-6mol/L ATRA for 0, 48, 72, 96 hours. The substrates were captured with 40 μg/L E-selectin overnight and the shear stresses were set to 0.02, 0.04, 0.06 Pa. RESULTS AND CONCLUSION: The velocity of untreated/treated HL-60 cells decreased firstly and then increased with monotonously increasing shear stress. On the contrary, the mean stop time and factional stop time increased firstly and then decreased. Therefore, we deduced that the flow enhanced rolling adhesion was regulated by the catch bond for the HL-60 cells rolling on E-selectin under flow. On the other side, rolling velocities decreased under the same shear stress even if treated with or without ATRA, and the mean stop time and factional stop time increased inversely, which further illustrate the rolling velocity is mainly regulated by stop time.

OBJECTIVETo discuss the occurrence correlation between obstructive sleep apnea hypopnea syndrome (OSAHS) and gastroesophageal reflux disease (GERD).
METHODSForty-three patients suspected of laryngopharyngeal reflux disease underwent combined multichannel intraluminal impedance and esophageal manometry (MII-EM), twenty-four-hour esophageal and pharyngeal pH and impedance monitoring and PSG. Subjects were grouped according to the detections. The difference of the measurement between groups were Compared. The possible relationship between the two diseases was analyzed.
RESULTSFourteen of all the subjects can be diagnosed to have GERD (32.6%). Twenty-six can be diagnosed to have OSAHS (60.5%). There were 10 patients had OSAHS and GERD simultaneously, which took over 38.5% of the OSAHS group, and 71.4% of the GERD group. BMI (P = 0.000) and lower esophageal sphincter (LES) residual pressure (P = 0.021) were significantly different among the four groups OSAHS, GERD, OSAHS and GERD, and control (non-OSAHS and non-GERD), but no linear relationship between LES residual pressure and prevalence or severity of the two diseases was found. In OSAHS group, AHI were positively correlated with the following indictors: the DeMeester score (r = 0.45), acid exposure of the distal esophagus (r = 0.491). There seems to be no Linear correlation among reflux indicators, sleep indicators, and esophageal functional indicators in GERD group. Linear correlation was not found among reflux indicators, sleep indicators, and esophageal functional indicators in OSAHS and GERD group (P > 0.05).
CONCLUSIONSThe incidence and the severity of GERD and OSAHS were related to each other. Reflux events may aggravate OSAHS. The two diseases may have some relationship on the esophageal function, especially on the regulation of the LES pressure.
