ObjectiveTo explore the relationship between the change of serum lipid and pathological change of coronary artery in Kawasaki disease(KD) children.Methods62 children with pathological change of coronary artery in KD were divided into pathological of coronary artery group and normal coronary artery group.62 normal children were selected as control group in the same time.And then the serum lipid status of three groups were compared.ResultsThe TC (5.32 ± 1.74 ) mmol/L,( 5.24 ± 1.67 ) mmol/L,TG ( 1.67 ± 0.79 ) mmol/L,( 1.74 ± 0.65 ) mmol/L,LDL-C(2.87 ± 1.14 ) mmol/L,( 2.72 ± 1.08 ) mmol/L of KD of the two groups were lower than of the control group(3.08 ± 1.28) mmol/L,( 1.12 ±0.56) mmol/L,(2.37 ± 1.06) mmol/L(t =1.70,1.66,1.71,all P ＜0.05 ),and HDL-C( 1.03 ± 0.31 ) mmol/L,( 1.08 ± 0.57 ) mmol/L higher than that of the control group ( 1.65 ± 0.92 )mmol/L( t =1.54,P ＜ 0.05 ) ; There were no differences between two coronary artery groups.After treated,TC,TG,LDL-C of normal coronary artery group were decreased ( t =1.76,1.88,1.72,all P ＜ 0.05 ),and HDL-C was increased ( t =1.90,P ＜ 0.05 ).ConclusionThe child ren with KD had dyslipidemia,and the dyslipidemia was recovered slowly.So,it should be an index of early diagnose for KD with coronary artery lesion.

Objective To compare the clinical effect of montelukast sodium and ketotifen in the treatment of children with cough variant asthma,thus to provide theoretical basis for clinical treatment.Methods 61 children with cough variant asthma were randomly divided into control group and observation group according to the digital table method,31 cases in each group.Patients of two groups were all given antispasmodic and antitussive.The control group was given ketotifen tablets drug therapy,1mg/time,2 times/d,and the observation group was treated with montelukast chewable tablets,5mg/time,1 time /d.After 8 weeks of treatment,the clinical effects were compared between the two groups.Results The total effective rate of the observation group (96.77%)was higher than that of the control group (77.42%),and the difference was statistically significant (χ2 =16.65,P <0.05).The clinical symptoms improved time of the observation group was (5.78 ±1.36)d,which was shorter than (8.45 ±2.24)d of the control group,the difference was statistically significant (t =2.71,P <0.05).The recurrence rate of the observation group (6.45%) was lower than the control group (16.13%),the difference was statistically significant (χ2 =4.67,P <0.05 ). Recurrence time of the observation group was better than that of the control group,the difference was statistically significant (t =7.98,P <0.05 ).Conclusion The curative effect of montelukast special chewing tablets in the treatment of children with bronchial asthma is obviously superior to ketotifen,has less adverse reactions.It was worthy of clinical application.

The present paper reports the clinical observations on 45 cases of multiple myeloma. In 35 patients, the tumors were immunologically typed as type IgG in 16, IgA type in 9, 2 each of ?, ? type light chain disease (LCD) and double light chain disease (D-LCD). 2 of IgD type, 1 each of non-secreting type (n-SMM) and ? heavy chain disease (?HCD). Further immunological subtyping dis-closed that most of the cases belonged to IgG. ? and IgA1 ? types.

The origin of nerves innervating the small intestine and oral part of the colon of the cat was studied by means of the retrograde axonal transport of HRP. Twelve adult cats were used in this experiment. The proximal cut end of the superior mesenteric plexus was immersed in HRP solution, in order to localize the neurons which contribute fibers to this plexus. Neurohistochemical procedures were processed according to Mesulam's tetramethylbenzidine (TMB) method. HRP labeled cells or fibers can be identified bilaterally in the following places: 1. The dorsal motor nucleus of the vagus nerve; about 80% of the labeled cells were found in a region from 0.4mm below to 2.0 mm above the obex, approximately at the rostral two-thirds of the middle segment of this nucleus. 2. The reticular formation of medulla; only a few cells labeled and 92% of them were located in an area from 0.2, mm to 2.7 mm above the obex. 3. The coeliac-superior mesenteric ganglion complex; almost all of the labeled cells were concentrated in the caudal part of it, near the origin of the superior mesenterie plexus. 4. The nodose ganglion; most of the oval or round labeled cells were of medium or small size, their diameters vary from 30 to 40?m, and the average total numbers of the labeled cells were 661 in the left and 695 in the right ganglion respectively. 5. The spinal ganglia; small round or oval labeled cells (25～45 ?m in diameter) were found in the left T_2 to L_5 and right T_2 to L_4 ganglia, with the most heavily labeled segments at T_(13) and L_1 (left, mean 365; right, mean 34% of all labeled cells). The average total number of the labeled Cells were 1872 in the left and 1698 in the right side. 6. Transganglionic labeled fibers were seen in the gracile nuclei of one cat, suggesting that HRP molecules are transported retrogradely in the peripheral process and anterogradely in the centrally projecting process of the same neuron of spinal ganglia.

Objective:To observe and analyze the therapeutic effect and safety of tirofiban combined large dose statin in patients with acute myocardial infarction (AMI),and evaluate its influence on myocardial perfusion and cardiac function.Methods:A total of 97 consecutive AMI patients visited to our hospital from May 2011 to January 2013, who were beyond the emergency PCI time window (≥12h),their chest pain was remissive or not further aggravated were studied.All patients were pumped with tirofiban for 48h continuously;according to combined rosuvastatin dose,they were divided into large dose group (n = 52,20mg,once/d,until one month after infarction,then changed to routine dose of 10mg,once/d)and routine dose group (n=45,10mg,once/d).All patients received se-lective PCI after 7 ~ 10d conservative treatment.Myocardial perfusion level,left ventricular ejection fraction (LVEF)on one week after PCI and 30d after AMI,enzymology changes [creatine (CK),lactate dehydrogenase (LDH)]and major adverse cardiovascular events (MACE)during hospitalization were compared between two groups.Results:Compared with routine dose group,there were significant reductions in thrombus scores in infarct related artery (IRA)[(1.32±1.01)scores vs.(0.81±0.78)scores]and corrected TIMI frame [(32.4±4.73)vs. (26.8±2.34)]in large dose group (P =0.021,P <0.001);after selective PCI,TIMI flow of large dose group was significantly better than that of routine dose group (P =0.024).On one week after PCI,LVEF:(51.4±8.9)% of large dose group was significantly higher than that of routine dose group (47.7±8.7)%,P =0.021;there were no significant difference in levels of CK and LDH between two groups on 7d and 30d after PCI (P >0.05).There was no MACE in both groups during hospitalization and 30d after PCI.Conclusion:Tirofiban combined large dose statin is safe and effective in patients with acute myocardial infarction,it can reduce intra-coronary thrombus burden,im-prove myocardial tissue perfusion and cardiac function without increasing MACE.

Objective To investigate the clinical significance of serum pepsinogen (PG) in gastric cancer screening. Methods The clinical data of 930 patients underwent colonoscopy were retrospectively analyzed. Among them, non chronic atrophic gastritis was in 550 cases (chronic atrophic gastritis group), chronic atrophic gastritis in 300 cases (chronic atrophic gastritis group), gastric cancer in 80 cases (gastric cancer group).

Objective:To study the anatomical correlation between dental arch and the volume of upper airway in patients with obstruc-tive sleep apnea hypoventilation syndrome(OSAHS). Methods: Dental arch architecture and upper airway volume were measured by cone beam CT(CBCT) in the subjects with OSAHS(n=22) and without OSAHS(n=19). The correlation between dental arch and the supper airway volume in OSAHS patients was analyzed. Results:The length of the upper dental arch and the height of palate in OSAHS patients were larger than those of the controls(All, P<0. 05). Cross-sectional area of nasopharynx and retropalatal and the total volume of upper airway were negatively correlated with the palatal height and upper dental arch length(P<0. 05), while positively correlated with upper dental arch of molar regions(P<0. 05). Conclusion:The abnormal shape of upper dental arch is related to the airway vol-ume of nasopharynx and retropalatal region in patients with OSAHS.
