ObjectiveTo discuss the incidence of negative emotion and behavioral problems between left-behind and non-left-behind children in rural areas during hospitalization. Methods175 participants included 90 cases of non-left-behind children patients and 85 left-behind children patients.The negative emotion and behavioral problems of all children were recorded and compared. ResultsCompared with the non-left-behind children patients,left-behind children manifested negative emotions such as anger,anxiety,depression and fear,more probability and incidence of behavioral problems such as dysphonia,special learning disabilities,sleep disorders,twitch disease,multiple tourtte's syndrome,attention deficit disorder,enuresis sickness and so on.There was significant differences between the two groups. ConclusionsCompared with the non-left-behind children,left-behind children patients are more likely to have negative emotion and behavioral prob-lems,it may have lasting influence on children and eventually influence the development of the physical and mental health,cause learning and adaptation difficulties.So more care and attention should be given to left-behind children,and given timely discovery and timely treatment of negative emotions and behavioral problems.

OBJECTIVETo evaluate the influence of naringin on PMMA-induced osteoclastic bone resorption using the mouse air sacs model.

METHODSTotal 48 female Balb/c mices with the age of 8 to 10 weeks were chosen in the study. Air were injected into the back in 32 mices and formed the air sacs, 6 d later, the skulls (originated from other 16 mices) were implanted to the air sacs. Thirty-two animals were divided into naringin treatment group (with 2 concentrations of 150 mg/kg and 30 mg/ kg) , DMSO group and PBS blank group, 8 animals in each group. Polymethylmethacrylate (PMMA) particles were injected into the air sacs in naringin treatment groups and DMSO group so as to irritate inflammatory reaction. Naringin with 2 concentrations of 150 mg/kg and 30 mg/kg were dissolved in DMSO of 0.2 ml, and were injected into air sacs, respectively. In PBS black group, no stimulation with PMMA particles, only injected PBS, and in DMSO group, injected DMSO without naringin. Tartrate resistant acid phosphatase (TRAP), Ca2+ release, modified Masson stain and histological analysis were performed on the 7th day after stimulation.

RESULTSCompared with DMSO group, naringin treatment group's cellular infiltration decreased (P < 0.01); concentration of 150 mg/kg was better than that of concentrations of 30 mg/kg (8.90 ± 1.75 vs 15.23 ± 1.86). Naringin can decrease calcium release in the lavage of the air sacs bone resorption model, especially obvious in naringin with concentration of 150 mg/kg. Naringin can ameliorate the inflammatory reaction and the subsequent bone resorption (including bone collagen loss, TRAP positive cells amount and so on) in air sacs with bone implant and PMMA particles. Naringin with concentration of 150 mg/kg appeared to be an optimal dosage to deliver the therapeutic effects.

CONCLUSIONNaringin inhibits PMMA-induced osteoclastogenesis and ameliorates the PMMA-associated inflammatory reaction and the subsequent bone resorption.

Objective:To develop non-immunized human phage display library.Methods:The total RNA of lymphocyte cells from peripheral blood of healthy voluntee was isolated and cDNA was synthesized,and the genes of heavy variable chain (VH) and light variable chain (V? and V?) were amplified by direct PCR and half-nested PCR.By overlapping extension PCR,the genes of VH and VL (V? and V?) were linked.The linked genes of single chain Fv fragment (scFv) were ligated with the vector pCANTAB-5E and then cloned into TG1 for the scFv library construction.Results:By direct PCR and half-nested PCR,42 VH fragments,16 V? and 18 V? fragments were obtained.The size of linked scFv library genes was 750 bp and the volume of constructed scFv library was 1.35?108.The results of BstN Ⅰ analysis of scFv genes from the phage library showed that fingerprint map of the selected scFvs was different.Conclusion:The developed phage library is diversity and can be used for selecting humanized scFv.

Objective:To study the wound healing effects of the extracts of Shengji Huayu Fang with different solvents and demon-strate their important role in wound healing for deep second degree burn wound. Methods:Sixty Sprague-Dawley rats were randomly di-vidied into six groups(ten rats in each group): the control group (saline), the positive control group (asiaticoside group), Shengji Huayu Fang group respectively with petroleum ether, chloroform, ethyl acetate and n-butanol as the extraction solvent. The extracts of Shengji Huayu Fang with different solvents were applied in the rats with deep second degree burn wound, and the wound healing was e-valuated by the healing rate judged by naked eyes and computer image analysis, DNA cell cycle analysis using a flow cytometry, patho-logical reports and the degree of re-epithelialization studied by the other methods. Results:The mean healing time of the chloroform ex-tracts group [(15. 67 ± 1. 12)d] was much shorter than that of the control group [(22. 87 ± 1. 01)d, P<0. 01]. The hydroxyproline content and the percentage of S-phase cells in wound tissue in the chloroform extracts group was obviously higher than those in the con-trol group (P<0. 01). Conclusion:The present study indicates that topical application of chloroform extracts of Shengji Huayu Fang is beneficial to burn wound healing, and the chloroform extracts of Shengji Huayu Fang is the main bioactive fraction.
