A description of the contents, indexes, and method appropriateness for supervision and appraisal of the tobacco control management in hospitals, and an insight on the regularity and effectiveness of building tobacco-free hospitals. The dual indexes of intervention and outcome were ascertained from both dimensions of the management process and effect; in terms of methodology, the paper described the time appropriateness of the supervision focus, management effectiveness of the supervision and appraisal areas, priority of supervision objects, population appropriateness of the supervision and appraisal indexes, method appropriateness of the supervision, appraisal and penalty, as well as the conditional support for supervision and appraisal. It is pointed out that timely summary and appraisal, proper conditional support and circular work chain, can help consolidate tobacco control in hospitals.

Objective This study aimed to investigate the role of pyrroloquinoline quinone (PQQ) in repairing oxidative nerve cells,and to study the antioxidant capacity of PQQ on the oxidative damage of rats caused by apolexis,as well as the effects on learning and memory abilities of apolexis rats.Methods Oxidative damage of PC12 was induced by H2O2,and the repairing rate of PQQ on oxidative PC12 cells was tested by methylthiazolyldiphenyl-tetrazolium bromide assay kit.The 18-month-old male SD rats were administered PQQ (0,10,20,40 mg/kg).After 4 weeks,Morris water maze test was used to test the learning and memory ability.After 6 weeks,serum and brain tissue related indicators and antioxidant capacity were recorded.Results The survival rate of PC12 cells increased from 59.1% to 90.5% with 200 nmol/L PQQ.Compared with the apolexis model group,the latency of the PQQ group (20,40 mg/kg) was shortened in the Morris water maze experiment,the swimming distance was reduced,pass-through counts were increased,and the first secure platform pass-through was reduced.Meanwhile,the levels of malondialdehyde and lipofuscin in serum and brain tissue of PQQ group decreased,the levels of superoxide dismutase,glutathione peroxidase vitality,antioxidant capacity of PQQ group (20,40 mg/kg) were enhanced.Conclusion PQQ could repair the oxidative damage of nerve cells,and it was confirmed that PQQ could play the same antioxidant effect in body and brain,and increase the learning and memory ability of apolexis rats.

This paper introduced the legislative development of community benefits system of nonprofit hospitals at federal level in the United States,as well as state legislatures in this regard. Based on America's experiences, an analysis was made on the "community benefits and health promotion model", which refers to community health needs assessment, health promotion programs, program implementation, supervision and appraisal. Thus the authors put forward inspirations for the social responsibility system development of public hospitals in China as follows. This refers to the establishment of hospitals' social responsibility system; development of community health promotion planning based on health needs;and establishment of social responsibility information disclosure system for fulfillment of their social responsibilities.

Information disclosure is important for the government and society to monitor the fulfillment of social responsibility of hospitals. This paper introduced the existing legislatures of the community benefits information disclosure system for non-profit hospitals in the United States, and analyzed the "two-level and two-way reporting system" of these hospitals, based on facts of California, Illinois and other regions. In the end, the authors put forward inspirations for the development of public hospitals' community benefits system in China as follows. This refers to the establishment of a social responsibility reporting system,stipulating the hospital and its health authority as the entities accountable for disclosure;a two-level/two-way reporting mechanism to improve the integrity of information disclosure;and standardization of information disclosure content and better timeliness and accessibility of information disclosure.

Objective To explore the diagnosis of clinically suspicious von Willebrand disease(vWD)in a family and its pathogene-sis.Methods The pedigree information and the biological specimen were collected from the clinically suspected VWD patient and her family members(4 persons in total)in Peking University First Hospital.The levels of platelet count(PLT),activated partial thrombo-plastin time(APTT),vWF antigen(vWF:Ag),vWF activity(vWF:Ac)and FⅧ activity(FⅧ:C)were detected,and vWF risto-cetin cofactor(vWF:RCo)assay,ristocetin-induced platelet aggregation assay(RIPA)and vWF collagen binding(vWF:CB)assay were performed for phenotype diagnosis.The peripheral blood genomic DNAs were extracted from the proband and her family members to perform whole-exome sequencing for identifying the mutation of vWF gene,The mutation site was analyzed by using bioinformation tools to explore the pathogenesis of the proband.Results The APTT of proband(m 1)was slightly prolonged and her vWF:Ag,vWF:Ac,vWF:RCo and vWF:CB were significantly decreased.There was no obvious aggregation in RIPA assay(1.0 mg/mL and 1.25 mg/mL).In her father(Ⅱ3),APTT,FⅧ:C,vWF:Ag,vWF:Ac and vWF:CB were normal,but vWF:RCo was slightly decreased.In her mother(Ⅱ4),APTT,FⅧ:C,vWF:Ag,vWF:RCo and vWF:CB were all normal,but vWF:Ac significantly decreased.In her brother(Ⅲ2),APTT and FⅧ:C were normal,but vWF:Ag,vWF:Ac,vWF:RCo and vWF:CB were reduced to varying degrees.In all the family members(father,mother and brpther),no apparent aggregation in RIPA(1.0 mg/mL)was shown.Genetic analysis showed that the proband(Ⅲ1)carried a compound heterozygous mutation of vWF gene c.7288-9T>G and c.1117C>T,her father(Ⅱ3)carried vWF gene c.7288-9T>G heterozygous mutation,and vWF gene c.1117C>T heterozygous mutation was presented in both mother(Ⅱ4)and brother(Ⅲ2).Conclusion According to the results of laboratory tests,the proband was diagnosed as type 2A vWD.The hetero-zygous mutation in vWF gene c.1117C>T and c.7288-9T>G may be the molecular mechanism leading to type 2A vWD in the proband.
