AIM:To explore the clinical therapeutic effect and safety of cervical cancer treated with neoadjuvant chemotherapy with gemcitabine hydrochloride.METHODS:60 patients with cervical cancer were randomly divided into the intervention group(30 cases) and control group(30 cases).The intervention group were treated with neoadjuvant chemotherapy with gemcitabine hydrochloride and cisplatin,the control group were treated with mitomycin and cisplatin.The status of clinical symptoms,size of tumor,side effect of chemotherapy and postoperative pathological analysis were observed and compared.RESULTS:Comparing the re- sults of two groups of patients,the intervention group was significantly higher than control group(P

Sterol 14alpha-demethylase (CYP51), the most widely distributed member of the P450 superfamily, is the key enzyme in sterol biosynthesis pathway. CYP51 is not only an important model for fundamental P450 structure/function studies, but also an important target protein of cholesterol-lowering agents, antifungal drugs and herbicides. This article reviewed the research advances in CYP51 at various aspects, including sequence characteristics, physiological roles, catalytic properties in vitro, protein structure, structure-function relationships and inhibition of CYP51. The problems remained in current research and designations of CYP51 inhibitors are also discussed.

OBJECTIVETo compare the changes of diagnosis, treatment and control of 0-14 years old urban asthma children during 10 years.

METHODThe questionnaires were given to diagnosed asthmatic children during the national epidemiological survey of asthma in children in 2000 and 2010 to understand the diagnosis and treatment of asthma and the status of the disease control. Children with asthma of a total of 36 cities were involved in this study, and the diagnosed asthma children in recent 2 years were 6,128 and 8 174, separately. Data were stored using epi-info software by double entry, V19.0 of SPSS was used to do the statistical analysis , χ(2) test was used.

RESULTThe proportion of correct diagnosis of asthma before investigation in 2010 was 64.6%, while it was 70.7% in 2010, which showed a significant increase (χ(2) = 59.3, P < 0.01). Diagnosis rate of asthma onset within 1 year was separately 50.8% and 78.6% in 2000 and 2010. The early diagnostic rate was significantly higher in 2010 than that in 2000 (χ(2) = 817.7, P < 0.01). In 2000 and 2010 children with asthma medication in the use of inhaled corticosteroids was 36.3% and 61.7%, it increased by 0.7 times in 2010 (χ(2) = 907.5, P < 0.01). Systemic corticosteroids utilization rate was separately 74.2% and 39.1% (χ(2) = 1 730.6, P < 0.01). Beta 2 agonists utilization rate was separately 71.8% and 73.4%, showing a slight rise (χ(2) = 4.3, P < 0.05). Antibiotics usage was separately 97.4% and 76.0%, compared to a decrease of 21.4% (χ(2) = 1 274.2, P < 0.01). In the survey of 2000 and 2010, children with acute asthma attacks within recent 1 year were separately 86.3% and 77.0% (χ(2) = 194.0, P<0.01), hospitalizations for asthma attack were separately 54.0% and 47.3% (χ(2) = 61.7, P < 0.01), rate of absence from school due to asthma less than 10 days was separately 47.5% and 71.4% (χ(2) = 682.6, P < 0.01).

CONCLUSIONThe rates of correct diagnosis and early diagnosis of asthma in urban Chinese children within 1 year had a significant increase compared with a decade ago. Inhaled corticosteroids therapy had increased by 0.7 times than before while systemic corticosteroids utilization rate significantly decreased. Antibiotics usage had a decrease of 22.0% but they were still overused. Asthma control was significantly improved, but acute exacerbations and hospitalizations of asthma children still accounts for a large proportion although they both had a great improvement.

OBJECTIVETo investigate whether the impairment of grafted liver after transplantation was induced by the same inflammatory cells in cold and warm ischemia.

METHODSMale SD rats were divided into two groups randomly, 24 grafted livers in each group were stored for 120 or 240 min at 4 degrees Centigrade Ringer's solution. Also male SD rats were divided into three groups, in which 24 grafted livers in each group were experienced warm ischemia ranged from 90, 120 to 150 min from non-heart-beating donor. The recipients were killed after 1, 3, 6, and 24 hours of transplantation for sample collection.

RESULTSAlong with the prolongation of cold and warm ischemia time, the serum ALT and AST levels were increased gradually after transplantation. Light microscopy showed some necroses in hepatocytes after 3 and 6 hours of transplantation in cold ischemia, and some neutrophilic infiltration in sinusoids. There were a large number of hepatocytes necroses after 3, 6 hours of transplantation in warm ischemia from non-heart-beating donor and a lot of lymphocytic infiltration in sinusoids. The findings in electron microscopy were as the same as those found in light microscopy, and the lymphocytes which infiltrated in sinusoids in warm ischemia were identified as T lymphocytes in electron microscopy.

CONCLUSIONSThe impairment of grafted livers after transplantation seems to be induced by two different inflammatory cells in cold and warm ischemia, that is, neutrophils mediate the cold ischemia-reperfusion, and T lymphocytes mediate the warm ischemia-reperfusion from non-heart-beating donor.

Objective To explore the prevalence and clinical characteristics of food allergy in bronchial asth-matic children less than 14 years old in China. Methods A case - controlled study was designed. The questionnaires were given to children,who were diagnosed to be asthmatic during the national epidemiological survey of asthma in chil-dren in 31 cities from September 2009 to August 2010. Non - asthmatic children,matched with the cases in age and gender,were selected during the same survey as control subjects if they were matched with the cases in age and sex. In-formation regarding the food allergen and symptom of food - induced anaphylaxis was analyzed. The difference in food allergy was compared between children with or without bronchial asthma. Results As a result,9235 asthmatic children and 11391 control subjects were enrolled in the case - control study. There were 14. 66％(1354 / 9235 cases)of the asthmatic children who had food allergy,compared to 3. 99％(455 / 11391 cases)of the non - asthmatics children, and the findings showed a significant difference (χ2 = 725. 25,P < 0. 001). The most common food allergens were fish and shrimp in both groups,and the difference was not significant [44. 09％ (597 / 1354 cases)vs. 42. 20％ (192 / 455 cases),χ2 = 0. 50,P > 0. 05]. The rate of peanut allergy was 4. 58％ (62 / 1354 cases)and 1. 54％ (7 / 455 cases) (χ2 = 8. 58,P < 0. 05),respectively. And the rates of fruit allergy in the asthmatic group and the non - asthmatic group were 14. 03％(190 / 1354 cases)and 27. 69％(126 / 455 cases)(χ2 = 44. 01,P < 0. 05),respectively. Cutaneous and nasal symptoms were common clinical manifestations. The rates of rash,pruritus,and swelling sympions were 47. 27％(640 / 1354 cases)and 61. 32％(279 / 455 cases)(χ2 = 26. 90,P < 0. 001),respectively for asthmatic group and non -asthmatic group. Rates of nasal symptoms were 17. 13％(232 / 1354 cases)and 10. 55％(48 / 455 cases)(χ2 = 11. 29, P = 0. 001),respectively in the asthmatic group and the non - asthmatic groups. Respiratory symptoms,such as cough and wheezing,were 25. 33％(343 / 1354 cases)and 5. 49％(25 / 455 cases)(χ2 = 80. 72,P < 0. 001)in 2 groups. Twenty cases of 1354 asthmatic children had severe food allergy,while such severe conditions occurred only 1 child without asthma (455 cases)occurred severe condition (1. 48％ vs. 0. 22％,χ2 = 4. 96,P < 0. 05). Conclusion The-rate of food allergen sensitization is highly prevalent in the children with asthma. Compared to those without asthma, and their types of food allergen and clinical symptoms are different from the latter.

Objective:To analyze and summarize the clinical features of wheat allergy in children, and to increase the awareness and diagnosis of food allergy in children.Methods:Children suspected with wheat allergy in the Department of Allergy, Children′s Hospital of Capital Institute of Pediatrics from December 2018 to November 2019 were included.Clinical data were collected, including the demographic profile, serum allergen specific immunoglobulin E(IgE) detection, peripheral eosinophil detection, and skin prick testing.Results:A total of 21 cases were included, consisting of 15 males and 6 females, aged (21.5±12.8) months.The children developed allergic symptoms after intake of wheat products or contact with wheat flour.The most common clinical manifestations were cutaneous (20/21 cases, 95.2%), followed by respiratory (7/21 cases, 33.3%), digestive (6/21 cases, 28.6%) and nervous (1/21 cases, 4.8%) symptoms.Eleven children had anaphylaxis.Laboratory allergy test showed that the detection level of serum wheat-specific IgE in 21 children was 1.46 to 100.00 kU/L, and when the specific IgE level was in grade Ⅴ or above, the risk of serious allergic reaction was increased in children ( P<0.05). Five of them tested positive in the wheat skin prick test.The peripheral eosinophil ratio in children was 0.04-0.12.All children had a history of other food allergies and family allergies. Conclusions:Wheat allergy in children has early onset and diversified clinical manifestations, mainly skin symptoms.Serum specific IgE detection shows an important role in the diagnosis and evaluation of wheat allergy.The highly sensitized individuals are prone to anaphylaxis.

Objective:To explore the level of fractional exhaled nitric oxide (FeNO) in preschool children in Beijing and analyze the influencing factors.Methods:Preschool students aged 3-5 in Beijing were selected from May to July 2017.Healthy children were screened through questionnaire survey and on-site physical examination, and their FeNO levels were detected.Results:A total of 317 healthy children were enrolled, including 161 males and 156 females.There was no significant difference in FeNO levels between different genders ( P>0.05). The geometric mean value of FeNO was 8.2 ppb in male(95% CI: 7.0-9.3 ppb)and 8.7 ppb in female (95% CI: 7.4-10.1 ppb). There were statistical differences in FeNO levels among the 3 age groups ( F=4.63, P<0.05). The geometric mean value of FeNO was 7.2 ppb in 3-year-old children (95% CI: 5.5-8.9 ppb), 8.8 ppb in 4-year-old children (95% CI: 7.4-10.2 ppb), and 9.2 ppb in 5-year-old children (95% CI: 7.7-10.7 ppb). The geometric mean value of FeNO of healthy preschool children was 8.5 ppb (95% CI: 7.6-9.3 ppb). There was a positive correlation between FeNO and height ( r=0.135, P<0.05), but there was no significant correlation between FeNO and weight. Conclusions:The geometric mean value of FeNO in healthy preschool children in Beijing is 8.5 ppb (95% CI: 7.6-9.3 ppb)and the 95% reference value is 23.5 ppb.The level of FeNO changes slightly with the increase of age, and height also affects the FeNO.It is highly feasible to use on-line tidal breathing method to measure FeNO of preschool children.

Objective To investigate the prevalence of food allergy among children living in metropoli-ses aged 0-14 years. Methods In this cross-sectional study a questionnaire was distributed to parents taking care of children aged 0-14 years from China′s 31 metropolises to get the parents reported prevalence. Results A total of 337560 children aged 0-14 years participated in the survey. There are 19676 children reported with food aller-gy(5. 83%). In different regions,the parents reported prevalence of food allergy had significant difference(χ2 =657. 01,P<0. 001). It was highest in the eastern (7. 38%,5259) and the northeastern (7. 03%,2916) part of China,and was lowest in the northwestern part of China,which was 4. 35%. Of all the 31 surveyed metropolises, the parents reported prevalence of food allergy was highest in Qingdao,and lowest in Lhasa,which was 9. 11%(917/10066),and 2. 33% (116/4984)respectively. The prevalence of food allergy in males and females was 5. 87% and 5. 79% respectively,with no significant difference (χ2 =1. 078,P=0. 299). The prevalence of food allergy in preschool children (3-5 years old,6. 65%) was higher than other ages (χ2 =46. 469,P<0. 001). Of children reported to have food allergy,38. 5% had a history of eczema,23. 0% had a history of allergic rhinitis, and 37. 7% had a family history of allergic diseases. Conclusion The parents reported prevalence of food aller-gy among children 0-14 years old from 31 metropolises in China was 5. 83%. In different regions cities and a-ges,there′s significant difference of the reported prevalence. There′s no significant difference of parents reported prevalence between males and females. The study would have great significance in reflecting and evaluating the prevalence of food allergy among children.
