Objective To explore methods to develop a hospital quality of care index system of county level hospitals based on the homepage of inpatient medical records and examine the validity of this system. Methods By means of literature review, homepage data and panel discussion, along with theories and statistical methods, indexes were identified. The dimensions and indices of the index system were pinpointed. Confirmatory factor analysis and normalization methods were combined to calculate the weights and scores of such indices. Scores were adjusted by Charlson comorbidity index ( CCI) with multi-regression method. The hospitals were ranked by adjusted scores in each dimension. The validity was evaluated by comparing the application results to universally acknowledged standards, such as hospital level and economic level of the geographic areas. Results An index system with 6 dimensions and 25 indices was developed, and the application results proved valid to some extent. The adjustment of CCI also proved effective. The 6 dimensions were correlated yet their directions were not consistent. Conclusions The methods and data used to develop the system have demonstrated strong operability and availability. The application results can reflect medical care quality in different aspects making it applicable among homogeneous hospitals. It is meaningful to assess dimensions respectively.

Objective To discuss cause and treatment measures of the postoperative failed to fully automatic nail in patients with circumcision by disposable circumcision suture device, so as to improve the quality of the circumcision.Methods 182 cases received circumcision by disposable circumcision suture device were randomly selected from September 2014 to March 2015 in the hospital and divided into control group ( n =86 ) and treatment group (n=96).All the patients received oral antibiotics for three days conventionally.Patients in control group were dressing with 0.1%iodine after treatment, dressing change every two or three days, while the treatment group soaking with 30 mL to 40 mL compound prescription cortex phellodendri chinensis fluid for 15 min two times per day.The postoperative wound anastomosis nail loss effect in two groups were compared.Results The time of complete nail loss in patients soaking with compound prescription cortex phellodendri chinensis fluid was significantly shorter than that in patients dressing with 0.1% iodine (P<0.05), but there was no significantly difference of the first time to lose nail between two groups.The rate of complete nail loss in treatment group was 94 cases (97.9%), which was significantly higher than 68 cases (79.1%) in control group (χ2 =16.47,P<0.05). The adverse reactions were mild of two groups.Conclusion The compound prescription cortex phellodendri chinensis fluid has exact effect on postoperative wound anastomosis nail loss and recovery in patients’ with circumcision by disposable circumcision suture device.

Objective To explore the applicable conditions for using urine uranium monitoring data to assess personal internal doses with a view to providing references for the occupational health management and the urine uranium monitoring in nuclear industry sector.Methods The urine uranium levels were calculated, through simulation calculation set at 1 mSv effective dose arising from either acute or chronic ingestion of uranium compounds.The results were compared with the monitoring values of workers without occupational exposure history.The feasibility of urine uranium monitoring for dose assessment of internal radiation exposure was discussed.Results For special monitoring of acute ingestion, liquid fluorimetry can meet monitoring requirements of Type F uranium compound, Type M low enriched uranium and Type S naturally occurring uranium.For routine monitoring, only Type F low enriched uranium and Type M naturally occurring uranium can be detected at shorter monitoring intervals, But it was not suitable for Type S uranium compounds.Conclusions Background levels and detection limits should be considered when urine uranium is measured for the purpose of assessment or control of exposure to uranium and the interpretation of the results.

Objective To explore the bone marrow pathology ,diagnosis and differential diagnosis of Waldenstrom macroglobulinemia(WM). Methods 19 WM patients was examined by bone marrow aspiration (BMA) and bone marrow biopsy (BMB) for morphology. Flow cytometry (FCM) and immunohistochemistry (IHC) for immunophenotyping. Results Plasmacytoid lymphocytes were identified in 11 BMA. All of 19 BMB were involved by lymphoma cells. 17 cases showed a predominance of small lymphocytes and 2 of plasmacytoid lymphocytes. Typically plasmacytoid lymphocytes were not seen in 4 cases. Patterns of bone marrow involvement were as follow: diffuse (12 cases), nodular (4 cases), interstitial (3 cases). Immunophenotypically, FCM showed all cases were CD_(19)~+, CD_(20)~+, CD_(22)~+, CD_5~- and CD_(10)~-. IHC revealed small lymphocytes and plasmacytoid lymphocytes were Pax5~+ CD_(20)~+ and plasma cells were CD_(38) CD_(138)~+ CD_(20)~- Pax5~-. Conclusion Small lymphocytes proliferation with plasmacytic differentiation is the typical bone marrow pathologic features of WM. IHC is benefit for identifying lymphocytes and plasma cells components. The Combination of morphology, FCM and IHC is contributive to the diagnosis and differentiation of WM.

Objective Derived air concentration of Type F uranium compounds are calculated respectively in order to provide reference for the management and evaluation of occupational hazard factors in workplace.Methods The air concentrations in the workplace of Type F uranium compounds were derived respectively through numerical simulationn,from individual dose limits,acute poisoning and chronic chemical damage threshold.Results Under normal operation conditions,the concentration of 5 μg /m3 for Type F uranium compounds in air of workplace can meet the requirements of radiation and chemical hazard control.Open inhalation of 1.1 mg/m3 is acceptable in a short time.Conclusions It is feasible to establish a permissible concentration limit in workplace for Type F uranium compounds.

Objective To evaluate the difference of PC values based on GBZ 97-2002 and on GBZ 97-2009 for lung cancer cases in Chinese uranium miners.Methods Using 19 lung cancer data ascertained in the past epidemiological study,PC values were calculated according to GBZ 97-2002 and GBZ 97-2009.Results In the 19 lung cancer cases,those cases that could not be judged as radiogenic cancers based on GBZ 97-2002,but may be judged as radiogenic cancers with GBZ 97-2009.The probability was enlarged by 1.1 times at least.The major reason was that the used value was the upper limit of 95％ in GBZ 2009 but the median in 2002.Conclusions Compared to GBZ 97-2002,the criteria value of PC in GBZ 97-2009 drops obviously.

Objective To explore the effects of accumulated 60CD,γ-ray irradiation on small molecular metabolites in rats urine.Methods Ten healthy male SD rats were irradiated by 60Co γ-rays in 5 days and the accumulated doses were 0,0.2,0.4,0.6,0.8,1.0 Gy,respectively.The metabolites in urine of different groups were measured with 1 H-NMR combined with principal components analysis (PCA) and partial least square discriminate analysis (PLS-DA). Results The metabolites in rat urine were obviously changed after irradiation. Compared with control group,the amount of acetoacetate decreased after irradiation(t =29.7 -30.7,P ＜ 0.05 ),but its relative level was stable when the dose increased ( P ＞ 0.05 ).Meanwhile,the relative level of hippuric acid increased ( t =4.4 - 21.6,P ＜ 0.05 ) especially when the accumulated dose was higher than 1 Gy (t =21.6,P＜0.05). The relative level of proline,taurine and trimethylamine-N-oxide increased after irradiation with the same trend( t =3.5 - 13.4,4.7 - 11.5,2.9- 12.7,P＜0.05). Conclusions The acetoacetate,hippuric acid,proline,taurine,and trimethylamine-N-oxide may be applicable for biomarkers of accumulative irradiation on rat.

Objective To explore the applicable conditions for using urine plutonium monitoring data to assess personal internal doses,in order to provide references for the occupational health management and the urine plutonium monitoring in nuclear sector.Methods Using some plutonium mixtures from DOE nuclear facilities,as an example,the urine plutonium levels were estimated through simulation calculation at 1 mSv effective dose arising from either acute or chronic inhalation of plutonium compounds,respectively.The results were compared with the typical detection limit of radiochemical separation and α-spectrometry.The feasibility of urine plutonium monitoring for dose assessment of internal radiation exposure was discussed.Results Only for type M plutonium compunds,1 mSv detection limit can be achieved using radiochemical separation and α-spectrometry within 10 d after inhalation.Conclusions Before the monitoring plan of urine plutonium is made,detection limits of monitoring method should be considered.Internal dose could be accessed using workplace air monitoring and working hours when necessary.
