Objective To investigate the allergens of asthmatic children of the local area, and provide a reliable objective basis for the prevention, treatment and care of children with asthma. Methods Allergen skin prick test was performed on 217 asthmatic children in our hospital out-patient clinic and hospital from February,2008 to September,2009. All children were divided into three groups by age, there were 48 cases with asthma in the five-months to three-year-old group, 57 cases with asthma in the 3 year-old group, and 112 cases with asthma in the 5 to14 year-old group. The production of allergens developed 10 kinds of inhaled,7 kinds of food allergen with Beijing Union Medical College Hospital Research Center. Results The total positive rate of allergen skin prick test of asthmatic children was up to 89.4%. Conclusions Among the allergic factors, the inhaling allergens are the main factors at wheezing episodes in the local area, and dust mites, indoor dust are the main allergens in the inhaling allergens, in the allergic factors of food, sea shrimp is the important factor that could not be ignored to the wheezing episodes. Therefore, helping parents and children to avoid or reduce dust mites, room dust and sea shrimp exposure is the most basic measures for the prevention, treatment and care of children with asthma.

Objective To investigate the effects of remifentanil-indueed controlled hypoteusion (CH) on the cerebral oxygen metabolism in patients undergoing radical operation for gastric cancer. MethodsForty-two ASA Ⅰ or Ⅱ patients (26 male, 16 female) aged 30-64 yr with body nuts index < 30 kg/m2 undergoing elective radical operation for gastric cancer were randomly divided into 3 groups (n = 14 each): group R remifentanil-induced controlled hypotension; group N sodium nitroprusside-induced CH and group C normal BP. Radial artery was cannulated for continuous BP monitoring and blood sampling. A catheter was inserted into right internal jugular vein and advanced cephalad until jugular bulb for blood sampling. MAP, HR, ECG and SpO2were continuously monitored. Anesthesia was induced with midazolam 0.1 mg/kg, fentanyl 5 μg/kg, propofol 2 mg/kg and vecuronium 0.08 mg/kg and maintained with isoflurane (end-tidal concentration 1. 1% ), iv infusion of propofol (50-100 μg·kg-1·min-1 ) and remifentanil (0.1 μg·kg-1·min-1) and intermittent iv boluses of vecuronium. The patients were mechanically ventilated (VT 8-10 ml/kg, RR 12 bpm, I: E 1:1.5) after tracheal intubation. End-tidal CO2was maintained at 30-35 mm Hg. CH was started after abdomen was opened. In group R the remifentanil infusion rate was increased from 0.1 μg·kg-1·min-1 in 0.05 μg·kg-1·min-1 increment every minute until the1 μg·kg-1min-1 in 0.5 μg·kg-1·min-1 increment every minute until the desired BP was achieved. MAP was reduced to 70% of the baseline value but never below 50 mm Hg. CH induction time and BP recovery time were recorded. Arterial and jugular bulb venous blood samples were obtained before induction of anesthesia (T0), immediately before induction of CH (T1), at 10 and 30 min of CH (T2,3) and 20 min after termination of CH (T4). The arterial and jugular bulb venous O2content difference (Da-jvO2) and cerebral O2extraction rate ( CERO2) were calculated. The difference between arterial and jugular bulb venous blood lactic acid concentration (Da-jvL) was also calculated. Results The CH induction time and BP recovery time were significantly longer in group R than in group N, but BP was stabler during CH in group R than in group N. Compared with group C, Da-jvO2, CERO2and Da-jvL were significantly decreased in group R, while CERO2and Da-jvL were significantly increased in group N. Conclusion Remifentanil can effectively induce CH and reduce cerebral O2consumption in patients undergoing radical operation for gastric cancer.

Objective Based on the health standards for arsenic in drinking water recommended by WHO (0.01 mg/L) and adopted by decentralized rural water supply in China (0.05 mg/L), to explore the conditions of arsenic metabolism and levels of methylation in population consuming drinking water with different concentrations of arsenic. Methods Three hundred and forty-eight adults in Shanxi exposed to different concentrations of arsenic(≥0.05 mg/L, ≥0.01-0.05) in arsenic species , TAs , first methylation ratio (FMR) and SMR in lower exposure group and the control group. In higher exposure group, the FMR of adults aged over 60 years was significantly higher than that in groups of 18-39 years old and 40-49 years old (P0.05). Conclusion In higher exposure group, the 2nd reaction of the metabolic pathway is more active in female than that in male, and arsenic methylation capacity of the higher age group arise. No significant effects of gender and age on arsenic methylation capacity is found among population exposed to drinking water with lower level of arsenic.

OBJECTIVE:To explore the clinical efficacy and safety of Yunkang granule combined with dydrogesterone in the treatment of early threatened abortion. METHODS:128 patients with early threatened abortion were randomly divided into single drug group and combined medication group,64 cases in each group. Single drug group received Dydrogesterone tablet with first dose of 40 mg,then 10 mg,q 12 h until vaginal bleeding;combined medication group additionally received 8 g Yunkang granule, tid,until symptoms disappeared. Human chorionic gonadotropin (HCG),clinical symptoms remission time and disappearance time,pregnancy/childbirth complications,pregnancy outcome and neonatal adverse outcome,and the incidence of adverse reac-tions in 2 groups were compared. RESULTS:After treatment,HCG in 2 groups significantly increased,and combined medication group was higher than single drug group,the differences were statistically significant(P<0.05);clinical symptoms remission time and disappearance time in combined medication group were shorter than single drug group,the difference was statistically signifi-cant (P<0.05). There were no significant differences in incidence of pregnancy/childbirth complications,pregnancy outcome and neonatal adverse outcomes in 2 groups (P>0.05). The incidence of adverse reactions in combined medication group was 10.9%, which was significantly lower than single drug group (40.6%),the difference was statistically significant (P<0.05). CONCLU-SIONS:Both dydrogesterone alone and Yunkang granule combined with dydrogesterone show good efficacy in the treatment of ear-ly threatened abortion,but the remission time and disappearance time of clinical symptoms and adverse reactions in combined medi-cation group are less than that in single drug group.

A cross sectional study of 769 patients was performed to evaluate the association of blood uric acid with coronary heart disease (CHD) in different metabolic disorders. It showed that uric acid was not independently associated with CHD. However, when the other abnormal metabolic factors were absent, uric acid might be related to CHD.

Objective This investigation was launched to characterize the relationship between some popular sports and the meniscus injury as well as the impairment extent due to practice duration.Methods The overall 819 women aged 20-49 years from clinic service,hospital,community and gymnasium were selected to join the investigation.The participants practice yoga or any other popular sports including badminton,jogging,climbing hills for at least one hour per day.The subjects were diagnosed with meniscus injury by means of physical examination and MR imaging.All of the subjects were therefore divided into the case(273)and the control(546)pools.The nested case-control model was applied to assess the relative risk of the meniscus.The 181 yoga subjects had been further divided into three sub-groups of 3-6 months,6-12 months and over 12 months,and they were accordingly analyzed with the variables of the age,body mass index(BMI)and Lysholm score.Results The study showed that yoga was associated with higher risk(OR=1.621,P=0.008)of meniscus injury,but the other sports showed no statistically significant risk (badminton 0R=1.028,jogging OR=1.116,climbing hills OR=1.259).The trainees appeared to be statistically different between the groups of 3-6 months and over 12 months on the items of the Lysholm score(P=0.006)and BMI(P=0.003).Conclusion Yoga plays a risky role on the issue of meniscus injury comparing some other popular sports among young women.The yoga players who exercise longer got lower Lysholm scores and lighter weight.

Objective To evaluate the imaging features of acute necrotizing encephalopathy caused by children A H1N1 influenza.Methods CT and MRI brain imaging data of three children acute necrotizing encephalopathy caused by A H1N1 influenza virus and proved by clinical and laboratory investigation were analyzed.All the three children got CT and MRI scan because of coma while in hospital.Results All cases represented multifocal damage,and some were symmetrical.Bilateral thalamencephalons were involved in the all cases.Bilateral grey and white matters of frontal lobe,temporal lobe,parietal lobe and occipital lobe,and hippocampi,putamina,external capsule,brain stem,bilateral cerebellum,could be seen multifocal damage,and some were symmetrical.All the cases showed brain swelling in varying degrees.These region presented low density in CT,hypointensity on T1 weighted series and hyperintensity on T2 weighted series and FLAIR series in MRI.Conclusion The imaging features of acute necrotizing encephalopathy caused by children A H1N1 influenza represented multifocal and symmetrical damage and brain swelling.It may be characteristic that bilateral thalamencephaloas were involved.The patient was serious,and fatality rate was high.So we should pay much attention to acute necrotizing encephalopathy caused by children A H1 N1 influenza.

Objective To observe the effect of LIGHT on synovial macrophage-osteoclast difier entiation in rheumatoid arthritis.Methods Synovial macrophages were collected from 8 synovial tissues har vested from RA patients by digestion with conagenase.The macrophages from each patient were divided into 5 subgroups:group 1 was co-cultured with Macrophage Colony Stimulating Factor(MCSF).group 2 was co cultured with MCSF and LIGHT.group 3 was co-cultured with MCSF and Receptor activator for Nuclear Fac tor kB ligand(RANKL),group 4 was co-cultured with MCSF and LIGHT and RANKL group 5 was co-cul tared with LIGHT.After two weeks of culture.tartrate resistant acid phosphatase(TRAP)and F-actin staining were used to detect the formation of osteoclast on cover slip(CS).Functional evidence of osteoclasts was as sessed by the formation of resorption pits ou dentine slice(DS).Results TRAP and F-actin were both nega tive in group 1 and group 5 and no pit on dentine slice could be observed.In group 2.there were some small round and ovoid osteoclasts with TRAP(+)and F-actin(+).Pits on DS were small and discrete.In group 3. there were many large irregular osteoclasts with TRAP(++)and F-actin(++).The number and volume of pits were both increased.In group 4.there were even more and larger osteoclasts with TRAP(+++)and F-actin (+++).The pits were even larger and became confluent,ie,pits(++++).Conclusion LIGHT can promote RANKL-mediated osteoclastogenesis in RA synovial macrophages.and it can induce osteoclast formation through a mechanism independent of RANKL.
