Methods The patients were divided into control group and therapy group randomly. On the basis of the treatment for asthma, the control group and therapy group were treated with ipratropium bromide, ipratropium bromide combined with salbutamol, respectively. Results After treatment, the clinical symptoms such as cough, suffocated feeling, cyanosis and dififcult breathing were improved on different degree for both of the two groups. The levels of lung function indexes including FVC、FEV 1、FEV 1% and PEF and the total effective rate in therapy group were signiifcantly higher than the control group. Besides, no signiifcant adverse effect was observed. Conclusion The ipratropium bromide combined with salbutamol can be used to relieve asthma in children effectively and synergistically. The bioavailability and the compliance of children are good.

OBJECTIVE:To observe the efficacy and safety of Huanglian shangqing soft capsule in the adjuvant treatment of in-flammation around the implant. METHODS:40 patients(72 implants)with inflammation around the implant were randomly divid-ed into control group (20 cases) and observation group (20 cases). Control group received full mouth supragingival scaling tech-nique,subgingival curettage,root planing,occlusal adjustment,loose teeth fixation or removal can not be reserved teeth using ul-trasonic scaler row scaling postoperative with 3% hydrogen peroxide,0.9% Sodium chloride injection alternately flushing periodon-tal pocket,removing residue until the inflammation control after the break-adjusted+appropriate amount of Minocycline hydrochlo-ride ointment,along with fine needles inserted into the periodontal pocket wall slowly until bag after pushed into the bottom of Mi-nocycline hydrochloride ointment,slow retreated the drug overflow until the gingival margin,no gargle and drinking water within half an hour,once a week. Observation group additionally received 1.2 g Huanglian shangqing soft capsules,twice a day. 4-week was regarded as 1 course,and it last 2 courses.

Background Many researches have reported the high proliferation ability of pterygium tissue.However,the origin of cells in pterygium tissue and their role in pathogenesis and recurrence of pterygium are below understand up to now.Objective This study is to explore the role of bone marrow derived stem cells and progenitor cells in the pathogenesis of pterygium.Methods Informed consent was obtained from 12 patients with the pterygium stretching the edge of the pupil prior to this trail.Pterygium specimen was obtained from 8 patients with primary pterygium and 4 patients with recurrent pterygium during the operation.The normal conjunctival tissue was obtained from the location of 10 mm from the pterygium in the operation eye.The expression levels of marker of the primitive haematopoietic progenitors(AC133),marker of the haematopoietic progenitor cells and endothelium (CD_(34)),marker of haematopoietic and stromal progenitor cells (C KIT ),and differentiation antigen of bone marrow fibroblast cells and nonhaematopoietic progenitor cells 1 (STRO 1) were detected by using immunohistochemistry.Results Various progenitor cell markers originated from bone marrow,including CD_(34),AC133,C KIT,STRO 1,were positively expressed in pterygium specimen rather than normal conjunctival specimen mainly in the basal epithelium or stroma of pterygia tissue.Majority of the positive cells were seen in the head of pterygium.C KIT positive cells were observed mainly in the basal epithelium and stroma of pterygium.The morphology of positive cells varied upon different distribution.Fibroblast like and spindle shaped positive cells were seen in the stroma layer of pterygium,and round or ovoid shaped cells were in basal epithelial layer.The distribution and shape of positive cells for AC133 and CD_(34) were similar to ones of C KIT but numbers of cells were varied between them.C KIT,AC133 and CD_(34) positive cells were coexpressed in basal epithelium and vascular endothelium.Expression of STRO 1 was found in the stroma layer not in the basal epithelium of pterygium.Similar distribution,numbers and shape of positive cells were seen between recurrent and primary pterygium.Conclusion The cells with stem cells markers and progenitor cells markers originated from bone marrow may play a role in the pathogenesis of pterygium.

Objective To investigate the protective effects of mild hypothenmia on myocardium of porcine with septic shock. Method A total of 24 Guishou miniature pigs were randomly(random number) divided into the pre-shock mild hypothermia group, shock mild hypothermia group and shock normothermia control group with 8 in each group. After the anesthesia of pigs, E. coli endotoxin was injected into femoral vein to establish the sepsis model of swine. After modeling, normal saline was continuously administered into femoral vein of pigs in three groups with in-fusion pump at steady speed. In the pre-shock mild hypothermia group,4 ℃ normal saline was used for intravenous injection to produce mild hypothermia before E. eoli endotoxin injection. In the shock mild hypothermia group, 38 ℃ saline was used at first and the 4 ℃ saline was employed after the systolic pressure of mice dropped to 60% of the o-riginal pressure for one hour. In shock normothermia group,38 ℃ saline was used from the beginning to the end of the experiment. The hemodynamics, blood lactate, CtnI, coronary angiography for detecting TIMI flow and the ultra-structural changes under electron microscopy were observed 6 h and 12 h after temperature intervention. Results (1) In pre-shock mild hypothermia group, the findings in all of observation were better than those in shock mild hy-pothermia group and shock normothennia group 6 h and 12 h after temperature intervention (P < 0.01). (2) In shock mild hypothermia group, the CtnI was lower and the ultra-structural changes were less severe than those in shock normothermia group (P < 0.05), but there were no significant differences in blood lactate, TIMI and hemody-namies between shock mild hypotherrnia group and shock normothermia group (P > 0.05). (3) There were no sig-nificant differences in all measurements between shock mild hypothermia group and shock normothennia group after 12 hours later (P > 0.05). Conclusions Mild hypothermia has some protective effects on myocardium of swine with sepsis. If the mild hypothermia is employed before the emergence of shock, the protective effects would be more ef-fective and the cardiac function would maintain at higher efficiency. If the hypothermia is used after the occmTence of shock, it could blunt the cardiac damage and preserve the cardiac function in some extent.
