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 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.

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 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.

Objective To compare sinus tarsi approach(STA) and extensile L shape approach (ELA) in the surgical treatment of calcaneal fractures. Methods A total of 51 cases of calcaneal fractures treated from May 2014 to December 2016 were enrolled. Twenty of them were performed ORIF via the sinus tarsi approach, while the other 31 cases were performed ORIF via lateral extensile L shape approach. X-ray films were taken postoperatively to record the changes of B?hler angle and Gissane angle. The AOFAS, VAS and SF-36 scores were adopted to assess the therapeutic effect. Results The average follow-up period of STA group was 15.5 months. And patients in ELA group were followed up for an average period of 18.4 months. All the fractures in the series had a boney union at or before the final follow-up. The final correction of B?hler angle (34.60 ± 2.91)° , and Gissane angle (114.45 ± 2.91)° was significantly increased in the STA group; and the final correction of B?hler angle (33.55 ± 2.73)° , and Gissane angle (112.81 ± 4.15)° was also significantly increased in the ELA group; while there was no significant difference between the two groups. The final AOFAS scores , VAS scores and SF-36 scores of the STA were (83.56 ± 7.13), (1.78 ± 0.89), (88.95 ± 4.31) scores, while those in ELA group were (81.91 ± 9.89), (2.01 ± 1.33) and (86.65 ± 4.95) scores. There was no significant difference between the two groups (P>0.05). No wound problem happened in STA group, but there were 2 cases who had wound complications in ELA group. Conclusions No significant difference is found between the two groups in the short-term efficacy of the treatment for calaneal fracture. However, STA has the advantages of lower soft tissue complication rate.

The necessity and superiority of the surgical operation on children with floating knee injury and the fracture union and complications were investigated. Twenty-eight children with floating knee injury were subjected to open reduction and internal fixation or external fixator. The patients were followed up for 18 months to 7 years. The curative effectiveness was scored by Karlstrom criteria. The results showed that no nonunion or deformity was found. The affected limb was 1.2 cm to 1.5 cm longer in 2 cases, 0.8 to 1.2 cm shorter in 3 cases than the contralateral. No severe dysfunction of knee joint occurred. The excellent-good rate was 92.8% and the curative rate 71.4% respectively. So for children whose age is older than 5 years, it's a good way to treat the fractures of femur and tibia with open reduction and internal fixation or external fixator. The method can be advantageous for the nursing care, early function recovery, shortening of the hospital stay and avoidance of severe complications.

The bFGF plays an important role in embryonic development of tendons and ligaments and in the healing of injuried tendons and ligaments. The eukaryotic expression plasmid of rat basic fibroblast growth factor (bFGF) gene was constructed in order to further investigate the bFGF function in molecular regulatory mechanism in the repair of tendons and ligaments and to provide the foundation for the clinical application. The cDNA fragments of bFGF were cloned from the skin of rats by RT-PCR, and recombinated to the pMD18-T vector. The cDNA encoding bFGF was cloned from the pMD18-T vector by RT-PCR, digested with restriction enzyme EcoR I Pst I and bound to eukaryotic expression plasmid pIRES2-EGFP to construct eukaryotic expression plasmid pIRES2-EGFP-bFGF. The pIRES2-EGFP-bFGF was transfected into the tenocytes by lipid-mediated ransfection technique. MTT test was used to detect the biological activity of bFGF in supernatants after the transfection. The expression of type I and III collagen genes was detected by using RT-PCR. It was verified that the pIRES2-EGFP-bFGF was successfully constructed, and its transfection into tenocytes could significantly enhance the biological activity of bFGF, and increase the expression of type I and III collagen mRNA, suggesting that pIRES2-EGFP-mediated bFGF gene therapy was beneficial to the repair of tendons and ligaments.
