Objective To evaluate the clinical value of fractional exhaled nitric oxide (FeNO) level in asthmatic children to predict bronchial hyperresponsiveness by analyzing the correlation between fraction of exhaled nitric oxide and bronchial provocation test.Methods One hundred and fourteen asthma outpatients of Shengjing Hospital were enrolled, FeNO levels, spirometry and bronchial provocation test were measured.Results In the bronchial provocation test,there were 33 positive and 81 negative cases.The positive group had a significantly higher FeNO levels than the negative ones(19.0 × 10-9 vs.16.0 × 10-9 ,p =0.000).By the ROC curve, the best FeNO cut-off value to predict bronchial hyperresponsiveness was 38.5 × 10-9 with high specificity (92.6％) but relatively low sensitivity (36.4％).There was no relationship between methacholine provocative dose causing a 20％ fall in FEV1 (PD20-FEV1) and the level of FeNO.Conclusion FeNO level has important predicting value for bronchial hyperreactivity in children with asthma.The level of FeNO ＞ 38.5 × 10-9 has high predictive value in asthmatic children with bronchial hyperreactivity.

Objective To investigate the alteration of the cytoskeleton of airway smooth muscle cells in young asthmatic rats with airway remodeling and the effect of RhoA/ROCK signal pathway.Methods Airway smooth muscle cells (ASMCs) were primary cultured and purified from Sprague-Dawley(SD) rats that were induced by ovalbumin (OVA) inhalation for 8w,then incubated by Pho kinase inhibitor Y27632.Real time quantitative polymerase chain reaction (RT-PCR),Western blot,and immunohistochemistry were used to measure the alteration of F-actin,and α-tubulin in the cytoskeleton of airway smooth muscle.Results (1) The asthma group showed a high average gray value of F-actin in ASMC than control groups,especially 8 weeks;and were significantly down in the group after adding Y27632(P ＜0.01).(2) The intension and intensity of fluorescence signal of α-tubulin in asthma groups in 8 weeks were higher than control greup(P ＜0.01),and were significantly decreased in Y27632 group.(3) A higher expression of α-tubulin protein was shown in the asthma group in 8 weeks relative to control group(P ＜0.01),and was significantly down-regulated in Y27632 group(P ＜0.05).Conclusions Alteration of the cytoskeleton of airway smooth muscle exists in young asthmatic rats and the RhoA/ROCK signal pathway possibly plays a significant role.

Objective To investigate the epidemiology of 10 000 patients with mammary gland disease.Methods 10 000 mammary gland disease cages during 1987～2006 in Yangquan Tumor Institute were collected,all patients had integrity case files and were diagnosed by molybdenum target radiography,near infrared ray,sonography,aspiration-needle biopsy or polyrrhea smear examination.Results In 8919 outpatient treated cases,7493 suffered cyclomastopathy(84%).1081 cases were inpatient cared(11%),the top five mammary gland disease are:breast cancer 342 cases,cyclomastopathy 252 cases,adenofibroma 104 cases,intraductal papilloma 86 cases and ductal ectasia 76 cages.For breast cancer patients,there were 125 cases during 1987～1996,3 were 21～30 years old and 23 were 31～40 years old.The number during 1997～2006 was 217,24 were 21～30 years old and 69 were 31～40 years old.Conclusion In 10000 cases,there are 7745 cyclomastopathy patients(77.45%)which takes the first place.Especially for 342(3.42%)breast cancer cases,the incidence grew up and patients age was much younger.

Objective To study the characteristics of pulmonary function in atypical asthmatic children with chest tightness or sighing breath as the sole presenting manifestation,and explore the diagnostic values of fractional exhaled nitric oxide (FeNO) for the atypical asthma.Methods Seventy-nine atypical asthmatic children with chest tightness as the sole presenting manifestation during January 2012 to June 2015 were selected as subjects.All of the subjects performed spirometry,FeNO measurement,total serum IgE and specific IgE determination on their first visit,and with either positive bronchial provocation test or positive bronchial dilation test.As well as 100 healthy children who perfomred FeNO measurement were selected as control group during the same period.The pulmonary function data and FeNO values were analyzed in children who were finally confirmed as atypical asthma.Results In atypical asthma children,the abnormal rate of forced expiratory flow 50％,75％ (FEF50,FEF75) and maximum mid-expiratory flow (MMEF) were 27％,43％ and 33％.Methacholine provocation dose causing a 20％ fall in FEV1 (PD20-FEV1) were 0.41 (0.19 ～0.67)mg and were positively related with MMEF(r =0.301,P =0.007).FeNO concentration in atypical asthma patients were 13.0 × 10-9 (7.0 ×10-9 ～24.0 × 10-9),higher than that in control group(P ＜0.05).Significant correlations were found between FeNO and total serum IgE (r =0.672,P =0.001).No correlations were found between FeNO and FEV1 (P ＞0.05),between FeNO and FEV1/FVC％ (P ＞0.05) or between FeNO and PD20-FEV1 (P ＞0.05).The diagnostic values of FeNO for the atypical asthma were analyzed using the receiver operating characteristic curve,the area under the curve was 0.600.Conclusion The characteristics of pulmonary function in atypical asthma are hypofunction mainly in small airway and patients with lower MMEF had higher airway hyperresponsiveness.The diagnostic values of FeNO in atypical asthma are limited.

Objective To investigate the changes of the levels of interleukin(IL)-17 in bronchoalveolar lavage fluid (BALF) of BALB/c mice infected by mycoplasma pneumonia (MP).Methods Sixtyfour BALB/c mice were randomly divided into two groups,normal group (n =32) and MP infected group (n =32).The BALF and lung tissue of two groups were collected after MP infection on day 3,7,14,21,each time 8.HE staining was used to observe the pathological changes of the lung tissue.IL-17 content in BALF was detected by ELISA.Results The inflammatory changes of the lung tissue was the most obvious at 7 day,and had begun to subside at 14 day,disappeared at 21 day after MP infection.IL-17 levels in BALF were (53.783 ±2.218) pg/ml(3 day),(65.913 ± 10.693) pg/ml(7 day),(59.915 ± 8.085) pg/ml(14 day),(57.043 ± 11.997) pg/ml(21 day) in MP infection group,and (46.220 ± 3.260) pg/ml in normal group.BALF IL-17 content increased significantly in MP infection group compared with normal group(P ＜ 0.05).IL-17 content reached its peak on day 7 after MP infection (P ＜ 0.05).Conclusion MP infection increased the level of IL-17 in the mice of BALF,reaching the peak on day 7.MP infection may be involved in airway inflammation in asthma through the IL-17 pathway.

Objective To evaluate the association between fetal ventricular septal defects (VSD)and chromosomal abnormalities.Methods The 214 fetuses diagnosed VSD in the First Affiliated Hospital of Sun Yat-sen University from January 2008 to September 2011 were included.The VSD were categorized into 3 types:perimembranous,muscular and mixed (the defect could not be classified because the dimensions were larger than 5 mm) type.The perimembranous defect was subdivided into inlet and outlet subtypes.Complicated with other cardiac abnormalities/extracardiac abnornalities or not,the cases were divided into isolated VSD group,VSD complicating cardiac anomalies group (other cardiac and/or great vessels malformation),VSD complicating extracardiac anomalies group (include organ malformation and sonographic soft markers) and VSD with both cardiac and extracardiac anomalies group.G-banding chromosome analysis was advised for all cases.In cases that no karyotype was obtained,the phenotype of the newborns was examined by the pediatricians.And those appeared normal were defined as normal karyotype.Results (1) There were 134 (62.6％,134/214) perimembranous defects,including 91 (42.5％,91/214) inlet lesions and 43 (20.1％,43/214) outlet lesions.There were 35 (16.4％,35/214) muscular defects and 45 (21.0％,45/214) mixed type lesions.(2) Among the 214 VSD fetuses,46 (21.5％) were isolated VSD,34 (15.9％) were cases with other cardiac anomalies,87 (40.6％) were cases with extracardiac anomalies and 47 (22.0％) were cases with both cardiac and extracardiac anomalies.(3) The chromosomal karyotypes were obtained in 105 cases,and 21 cases were considered as normal according to the phenotype.Of all these 126 cases,46 (36.5％,46/126) had chromosomal abnormalities.(4) Inlet defects had the highest risk of chromosomal abnormalities (28/55,50.9％),while the muscular defects had the lowest risk (2/25,8.0％).The incidence of chromosomal abnormalities in outlet and mixed type was 33.3％ (9/27) and 7/19,respectively.The types of VSD were significantly correlated with chromosomal defects (P ＜ 0.01).(5) The incidence of chromosomal abnormalities in the 4 groups were 3.4％ (1/29),2/14,53.6％ (30/56) and 48.1％ (13/27),respectively.The risk of chromosomal abnormalities in the cases complicating extracardiac or both extracardiac and cardiac anomalies was significantly higher than the isolated VSD group (P ＜ 0.01).Conclusion Fetal VSD had a highest risk of chromosomal abnormalities,especially the inlet type and VSD with extracardiac abnormalities,and then the fetal karyotype should be recommended.

OBJECTIVE:To study the impacts of Zishenyutai pills on the ovarian tissue oxidative damage and Nrf2 protein ex-pression in rats exposed by electromagnetic radiation (EMR). METHODS:Accordiny to their weight,30 SD rats were randomly divided into normal group,radiated group and radiated-treated group with 10 rats in each group. Normal group were not radiated, and other 2 groups were exposed by 900 MHz radiation for 4 h every day;radiated-treated group was given Zishenyutai pills sus-pension [0.25 g intragstrically(medicinal materials)/ml] after radiation;normal group and radiated group were given constant vol-ume of normal saline intragastrically for consecutive 20 d. The rats were killed when they were at the estrum. The Nrf2 proteins ex-pression of ovary were detected by immunohistochemical method,the content of ovary MDA(malondialdehyde),and activity of to-tal superoxide dismutase (T-SOD) and superoxide dismutase (GSH-Px) were detected by biochemical method. RESULTS:Com-pared with the rats in normal group,the Nrf2 protein expression was higher in the rats of the radiated group;the content of ovary MDA was higher and activity of ovary T-SOD and GSH-Px were lower significantly(P<0.05). While compared with the rats in ra-diated group,the Nrf2 protein expression didn’t obviously change in the rats of the radiated-treated group(P>0.05),the content of ovary MDA was lower and activity of ovary T-SOD and GSH-Px were higher significantly (P<0.05). CONCLUSIONS:Zish-enyutai pills can prevent and cure ovary tissue oxidative injury induced by 900 MHz radiation,but have no effect on the expression of Nrf2 protein.

Objective To compare the efficacy of oxycodone versus sufentanil for intravenous analgesia after radical resection of pulmonary carcinoma performed via video-assisted thoracoscope.Methods One hundred fifty-four patients of both sexes, aged 18-64 yr, with body mass index of 18-25 kg/m2, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ , scheduled for elective radical resection of pulmonary carcinoma performed via video-assisted thoracoscope, were randomly divided into either sufentanil group (group S, n=76) or oxycodone group (group O, n =78) using a random number table.The 2 groups received combined intravenous-inhalational anesthesia.When postoperative visual analogue scale (VAS) score ≥ 4, sufentanil 5 μg or oxycodone 2 mg was injected intravenously, and the administration was repeated when necessary until VAS score ≤ 3.Patient-controlled intravenous analgesia (PCIA) was then used for postoperative analgesia (lasting for 48 h).PCIA solution contained tropisetron 20 mg and sufentanil 200 μg in 100 ml of normal saline in group S.PCIA solution contained tropisetron 20 mg and oxycodone 50 mg in 100 ml of normal saline in group O.The PCIA pump was set up to deliver a 2 ml bolus dose with a 10 min lockout interval and background infusion at a rate of 1 ml/h.VAS score was maintained ≤3.When VAS scores ≥4, morphine 10 mg injected intramuscularly was used as rescue analgesic.The requirement for rescue analgesic, level of patient's satisfaction with analgesia,and analgesia-related adverse events were recorded.Results The incidence of nausea and vomiting was significantly lower in group O than in group S (P＜0.05).There was no significant difference in the requirement for rescue analgesic, level of patient's satisfaction, and incidence of dizziness and over-sedation between the two groups (P＞0.05).No patients developed respiratory depression and pruritus in the two groups.Conclusion Compared with sufentanil, oxycodone can produce similar analgesic efficacy when used for PCIA after radical resection of pulmonary carcinoma performed via video-assisted thoracoscope, with lower incidence of nausea and vomiting.

Objective To explore the clinicopathological characteristics,immunohistochemical phenotype and differential diagnosis of ovarian seromucinous borderline tumor.Methods Fifteen cases of ovarian seromucinous borderline tumor in Shanxi Provincial People's Hospital from January 2013 to May 2017 were collected.The surgical specimens were observed after HE and immunohistochemical staining,the patients were followed-up,and the relevant literature was reviewed.Results The age of 15 cases of ovarian seromucinous borderline tumor ranged from 26 to 56 years(mean 37 years).Eight cases occurred in the right,5 cases occurred in the left,only 2 cases were bilateral tumors.The complaint of most patients was abdominal distention,3 cases was ascites.The maximum diameter of these tumors ranged from 4 to 13 cm(mean 9.3 cm).Grossly,15 cases mainly showed cystic performance,varying amounts of papillae inside wall of the cysts.Small region of 2 cases were solid.Microscopically,9 tumors were composed of endocervical-like mucinous epithelium,4 tumors were endocervical-like mucinous epithelium and serous epithelium.2 cases were accompanied with endometriosis.Tumor cells mainly expressed estrogen receptor(ER),progesterone receptor(PR),paired box gene protein 8(PAX-8),cytokeratin 7(CK7),these markers were immunophenotypes of Mullerian tumors.Followed up for 3 to 24 months(mean 16.7 months),2 cases showed bilateral tumors,1 case was peritoneal implantation.No tumor recurrence was found in the remaining 12 cases.Conclusions Different from mucinous borderline tumor,ovarian seromucinous borderline tumor possesses relative special clinicopathological features,morphological and immunohistochemical phenotypes,with better prognosis.Combination of immunohistochemical markers ER,PR,PAX-8,CK7,CK20,Vimentin,CDX-2 and WT-1 can make an accurate diagnosis of this tumor.

Objective To investigate the effect of the asthmatic mice's contents of nuclear factorerythroid-2-related factor 2,Nrf2 and HO-1 reated with curcumin in lung tissue.Methods All 45 mice were divided into three teams randomly,the normal mice,the asthmatic mice and the curcumin mice group.We tested the expression of Nrf2 and HO-1 of three mice teams in lung by immunolfluorescence technique.We tested the protein contents of Nrf2 and HO-1 of the three teams in the lung tissue by Western blot.We tested the binding activity of Nrff2 and ARE of the three teams in lung by EMSA.Results The expression of Nrf2 and HO-1 in curcumin group was significantly higher than that in asthma group and normal control group by immunolfluorescence technique.There was no sigrnificant difference in content of cytoplasm Nrf2 protein in lung tissue between three groups by western blot(P ＞ 0.05).The content of nuclear Nrf2 and HO-1 protein in the lung tissue of the curcumin group was significantly higher than that in the other two groups,the difference is statistically significant (Nrf2,P ＜0.05;HO-1,P ＜0.01).The binding activity of Nrf2-ARE in lung tissue of curcumin group was significantly higher than that of asthma group and control group,with statistical significance(P ＜ 0.05).Conclusion Curcumin can increase the protein contents of the Nrf2 and HO-1 of mice and enhance the expression of them.
