[Objective]To evaluate the preemptive analgesic effect and safety with celecoxib in patients undergone the hip joint replacement.[Method]Fifty patients scheduled for elective hip joint replacement were randomly divided into two groups,celecoxib group and control group.Those of celecoxib group were given celecoxib 200 mg 24,12 h before incision.The operation was performed under extradural anesthesia by the same surgeons. All patients were given celecoxib 200 mg 8,24,36,48,60,72 h after the operation.Before celecoxib administration and after the operation,pain intensity was measured using visual analog scale(VAS),and analgesic requirements,side effects,hip joint ranges of motion,sleep states,hemorheology and phlebothrombosises messured with the ultrasonic wave were compared.[Result]There were no marked differences in the VAS pain scores before celecoxib administration between two groups.Compared with control group,the patients of celecoxib group had significantly lower VAS pain scores after the operation(P

Objective To explore the microcosmic mechanism of pingyangmycin treating infantile proliferating capillary hemangiomas so as to find the optimal method for hemangiomas′ treatment.Methods Sixty samples of infantile proliferating hemangiomas were divided into control group(30 cases,aged from 2 days to 6 months) and experimental group(30 cases,aged from 2 to 6 months).Pingyangmycin was made into emulsion and smeared on the surfaces of the leision in experimental group with 3 times every day as well as only matrix in control group.The specimens were resected on d7,then made into pathological slices and electron microscope slices in order to observe the cells microcosmic structure changes and ultrastructure changes.Furthermore,the apoptotic indexes of two groups were detected by the molecular biology method(TUNEL test).Results The number of apoptotic cells were lower in control group(apoptotic index 18.87?13.67)but higher apparently in experimental group(apoptotic index 29.52?15.33).The difference between two groups was significant(t=2.842 P

Objective To investigate the mechanism of growth hormone inhibiting IPS-induced apoptosis of alveolar type Ⅱ epithelial cells in rats. Method Isolated and purified AEC Ⅱ cells of SD rats were divided into 5 groups,8 duplicate wells in each group. Group I served as control group; group Ⅱ:LPS 10 ug/ml;group Ⅲ:LPS 10 ug/ml + GH 50 ng/ml;gronp IV :LPS 10 ug/ml + GH 100ng/ml; group V: LPS 10 ug/ml + GH 200 ng/ml. LPS was finally added into wells in group Ⅱ～V . After the cells were incubated for 24 hours, the apoptosis rate and necrosis rate of AEC Ⅱ cells stained with Annexin V/PI were detected by flow cytometry and Fas protein of AEC Ⅱ cells were measured by immunocytochemistry. Results (1) The apoptosis rate and necrosis rate of AECⅡ cells in group Ⅱ,Ⅲ, Ⅳ and V were significantly hitOer than those in group Ⅰ( qapoptosis rate Ⅰ, Ⅱ =12.26,qnecroeis Ⅰ,Ⅱ=18.34, qapoptosisⅠ.Ⅱ=9.63,qnecrosisⅠ,nⅡ=5.75,qapotosisⅠ,Ⅳ= 9.15,qnecrosisⅠ,Ⅳ= 5.39, qapotosisⅠ,Ⅴ = 10.87, qnecrosisⅠ,Ⅴ = 5.91, P 0.05), but lower in group Ⅲ,IV and V than those in group Ⅱ(qapoptosis Ⅱ,Ⅲ= 15.24, qpecrosisⅡ,Ⅲ=16.38, qapoptosisⅡ.Ⅳ = 15.95,qnecrosisⅡ.Ⅳ=16.95, qapoptosis rate Ⅱ,Ⅴ=14.57, qnecrosisⅡ.Ⅴ = 15.61,P<0.05). (2)The positive rate of Fas expression on AEC Ⅱ cells in group Ⅱ,Ⅲ, Ⅳ and V was obviously higher than that in group Ⅰ. ( q Ⅰ.Ⅱ=35.67, qⅠ ,Ⅲ=14.32, qⅠ,Ⅳ = 13.87, qⅠ.Ⅴ=26.16, P<0.05), but lower in gronpⅢ ,Ⅳ and Ⅴ than that in gronp Ⅱ(qⅡ,Ⅲ=12.54, qⅡ,Ⅳ = 13.02, qⅡ,Ⅴ =6.96, P<0.05). Conclusions GH can probably de-crease the apoptosis of AEC Ⅱ cells by inhibiting Fas expression.

Objective To investigate the roles of adrenomedullin(ADM) and endothelin-1(ET-1) in left-to-right shunt congenital heart disease(CHD) complicated with congestive heart failure(CHF).Methods Plasma ADM and ET-1 concentrations were measured by radioimmunoassay in heart failure stage and recovery period of 18 infants with left-to-right shunt CHD.Also 20 healthy infants acted as control group were measured.Results Plasma concentrations of ADM and EF-1 were significantly higher in heart failure stage of left-to-right CHD infants than those in their recovery period,and both in their heart failure stage and in their recovery period were higher than that in control group(P

Study the infect of child anorexia granule on serum ghrelin and leptin of anorexia children and its clinical efficacy. Selected 81 cases of anorexia children aged 1-6 years old into treatment group (42 cases) and control group (39 cases), in addition, 30 case healthy children as healthy control group. The control group children were treated with domperidone suspension 0.3 mg x kg(-1) x d(-1), tid, orally 30 minutes before meals. Treatment group were treated with child anorexia granule, 1-3 years 1 package, bid; 4-6 years 1 package, tid; po, 4 weeks as a course of treatment. Study the change of serum ghrelin and leptin before and after therapy. The study demonstrates that before treatment, the serum ghrelin level of disease group was lower than healthy group (P < 0.01), and the serum leptin level was higher than healthy group (P < 0.01). After treatment, the serum ghrelin level both increase, and the serum leptin decline. And the change of treatment group was significantly different with control group (P < 0.01). And the clinical effective rate are 95.23% and 74.35% (P < 0.01). After 6 months of follow-up visit, the children weight significantly increase in treatment group (P < 0.01). Results indicate that child anorexia granule can facilitate secretion of ghrelin, and inhibit secretion of leptin, so as to work up an appetite. And the molecular mechanism is its infect on serum ghrelin, leptin.

Objective To explore the role of transfer network in critical neonatus treatment and its optimising strategy.Methods All the materials of critical neonatus who were transferred by network between Jan.2004 and Dec.2007 were collected,the establishment and mechanism of transfer network service,the change of transfer models,results and main factors influencing effect of transfer network in this pe-riod were analyzed.Software SPSS 11.0 was used to analyze the data.Results Two hundred and fifty-six critical neonatus cases were transferred by network between Jan.2004 and Dec.2007,accounting for 13.79% in all critical neonatus born in this period.The birth rate of critical neonatus decreased each year and also the proportion of transfer.The proportion significantly reduced during 2006-2007 compared with that in 2004-2005(P

OBJECTIVETo explore the effect of Danggui Yinzi (DY) on delayed allergy in model mice with qi-blood deficiency syndrome (QBDS).

METHODSQBDS model was established in 48 Kuming mice of SPF grade by using reserpine and acetophenone hydrazine. Forty of them were then randomly divided into the model group, the loratadine group, the high dose DY group, the middle dose DY group, and the low dose DY group, 8 in each group. Another 8 in line with the same standard were recruited as a blank group. Mice in high, middle, and low dose DY groups were administered with DY concentrated solution at 60, 30, 15 g/kg by gastrogavage. Mice in the loratadine group were administered with loratadine solution at 1.66 mg/kg by gastrogavage. Equal volume of normal saline was administered to mice in the model group and the blank group by gastrogavage. All medication was given once per day for 1 successive week. Except those in the blank group, the rest mice were evenly smeared with 1% DNCB solution on the abdomen. Five days after skin allergy, 1% DNCB solution was smeared to right ear of all mice to stimulate allergic reaction. Mice in the blank group were smeared in the same way without allergenic reaction. The auricle swelling and the inhibition ratio were determined at 24 h after attack. Blood was collected from orbit and serum IgE level detected using double-antibody sandwich ELISA.

RESULTSCompared with the blank group, auricle swelling obviously increased and serum IgE level was obviously elevated in the model group (P < 0.01). Compared with the model group, auricle swelling obviously decreased and serum IgE level was obviously reduced in the 3 dose DY groups (P < 0.05, P < 0.01). Meanwhile, the auricle swelling degree was superior in high and middle dose DY groups to that in the loratadine group (P < 0.05). The inhibition ratio of auricle swelling was sequenced from high to low as 67.3% in the high dose DY group, 56.0% in the middle dose DY group, 48.1% in the low dose DY group, 47.3% in the loratadine group.

CONCLUSIONSDY could inhibit auricle swelling and lower serum IgE level. It also could inhibit delayed allergic reaction in model mice with QBDS to some extent.

Background:The symptomatic bradyarrhythmia is Class Ⅰ indication for pacing therapy which is not a radical cure.The present study aimed to assess the feasibility and to present the initial results of the restricted ablation of the parasympathetic innervation surrounding sinus and atrioventricular (AV) nodes for treating patients with bradyarrhythmia.Methods:A total of 13 patients with cardiogenic syncope were included from May 2008 to June 2015.Under the guidance of fluoroscopy and/or three-dimensional geometry by 64-slice spiral computed tomography,atrial activation sequence in sinus rhythm was mapped.Chamber geometry was reconstructed manually or automatically using the Niobe Ⅱ magnetic navigation system integrated with the CARTO-remote magnetic technology (RMT) system.Cardioneuroablation was targeted at the high-amplitude fractionated electrograms surrounding the regions of His bundle and the site with the earliest activation in sinus rhythm.Areas surrounding the sinus node,AV node,and the phrenic nerve were avoided.Results:Thirteen patients completed the studies.Ablation was successfully performed in 12 patients and failed in one.The high-frequency potential was recorded in atrial electrograms surrounding the sinus or AV nodes in all the patients and disappeared in 15 s after radiofrequency applications.The vagal reaction was observed before the improvement of the sinus and AV node function.No complications occurred during the procedures.Patients were followed up for a mean of 13.0 ± 5.9 months.During the follow up ten patients remained free of symptoms,and two patients had a permanent cardiac pacemaker implanted due to spontaneous recurrence of syncope.The heart rate of post-ablation was higher than pre-ablation (69.0 ± 11.0 vs.49.0 ± 10.0 beats/min,t =4.56,P =0.008).The sinus node recovery time,Wenckebach block point,and atrium-His bundle interval were significantly shorter after ablation (1386.0±165.0 vs.921.0 ±64.0ms,t=7.45,P=0.002;590.0±96.0 vs.464.0± 39.0ms,t=2.38,P=0.023;106.0±5.0 vs.90.0 ± 12.0 ms,t =9.80,P =0.013 before and after ablation procedure,respectively).Conclusions:Ablation of sinoatrial and AV nodal peripheral fibrillar myocardium electrical activity might provide a new treatment to ameliorate paroxysmal sinus node dysfunction,high degree AV block,and vagal-mediated syncope.
