Objective To study the distribution and related factors of curative care expenditure (CCE) of injury in Gansu Province in 2017. Methods Based on the "A System of Health Accounts 2011 (SHA 2011)", the curative care expenditure of injury in Gansu Province was calculated and analyzed. The five?stage stratified cluster sampling method was adopted to extract 149 medical and health institutions, 120 township hospitals (including community health service centers), 150 individual clinics and 600 village clinics (including community health service stations). The top?down allocation method was used to calculate the cost of injury treatment in Gansu Province, and the influencing factors were analyzed by multiple linear regression. Results In 2017, the CCE of injury in Gansu province was 3.831 billion yuan, and the expense in general hospitals was 2.708 billion yuan. Among them, the cost of lower limb injury and head injury were 1.090 and 0.847 billion yuan. People aged 40 to 69 years old spent 1.901 billion yuan on injury treatment, and the CCE of injury treatment for men and women were 2.422 and 1.409 billion yuan respectively. The results of multiple linear regression showed that hospitalization expenditure was significantly associated with length of stay, operation, hospital grade, age, payment method and gender (P<0.001). Conclusion The economic burden of injury in Gansu Province is relatively heavy, so it is necessary to focus on preventions for different groups and costly injury sites.

One kind of new cefazolin sodium hydrate crystal was obtained in the isopropyl alcohol - water system. There are two symmetry independent molecules in the asymmetric unit, both being well ordered in the lattice, and ten independent water positions but generally four to six (mean five) water molecules and one sodium ion present in the unit cell structure. Huge solvent tunnels can be found. Again there are two general regions of water molecules, those in the large solvent tunnels and those in proximity of the sodium ion and the tetrazole moieties of the drug molecule. The physical and chemical characteristics of the new cefazolin sodium hydrate crystal are similar to that of the alpha-form cefazolin sodium crystal, and the new crystal has better chemical stability than amorphous cefazolin sodium powder.

The paper is to report the establishment of an HPLC method for determination of the components of bitespiramycin and its products, and to evaluate the components profile of bitespiramycin and its related products. Liquid chromatography combined with mass spectrometry (LC-MS) was used to identify the nine major components of the reference substance of bitespiramycins. The nine components of bitespiramycins and its products have been quantified by HPLC with gradients elution methods. The content of the component of 4"-O-isovalerylspiramycin III was not less than 35%, the content of the components of 4"-O-isovalerylspiramycin (I + II + III) was not less than 60%, and the contents of the nine components of bitespiramycin were not less than 80%, separately. In addition to the components mentioned above, there also exists some other impurities, however, with lower contents. This gradient elution HPLC method reported by this paper is considered to be suitable for the quality control of bitespiramycin.

OBJECTIVETo develop a method for quantifying gene expressions in the mouse single oocyte and preimplantation embryo.

METHODSWe quantified the message RNA (mRNA) expression of the TSC2 gene in the single oocyte and preimplantation embryo by capillary electrophoresis using the exogenic mutation TSC2 gene as the reference and amplification by competition polymerase chain reaction (PCR).

RESULTSWe successfully established the method for quantifying the mRNA expression of the TSC2 gene, with good linear relations between the mRNA level of the TSC2 gene and the dilution degree of the reference gene (r = -0.987).

CONCLUSIONThe level of the mouse TSC2 gene expression can be effectively quantified by competition PCR and capillary electrophoresis, which has provided a molecular base for evaluating the quality of human oocytes and preimplantation embryos.

OBJECTIVETo characterize histopathologic features of non-Alzheimer type dementia.

METHODSBodian, Gallyas-Braak silver staining, tau and ubiquitin immunohistochemistry were applied in an analysis of 22 cases of autopsy-proven neurodegenerative dementia. Appearance, distribution and immunoreactivity of neuronal and glial inclusions in the brain were observed. The final histological diagnoses were made according to the pathological criteria for several types of common non-Alzheimer type dementia.

RESULTSAmong the 22 cases of neurodegenerative dementia, 12 cases were identified as non-Alzheimer type dementia, including Pick's disease (2 cases), progressive supranuclear palsy (3 cases) and corticobasal degeneration (3 cases), dementia with Lewy bodies (1 case), and Parkinson's disease (3 cases). Another 10 cases consisted of pure Alzheimer's disease (AD, 9 cases) and AD combined with argyrophilic grain disease (1 case). Characteristic neuronal and glial inclusions, such as classical and cortical Lewy body, Pick body, Globous NFTs, astrocytic plaque and tufted astrocyte, argyrophilic grain were found in the brains of non-Alzheimer type dementia. Classical and cortical Lewy bodies were not argyrophilic but were immunoreactive to ubiquitin. Pick bodies, Globous NFTs, astrocytic plaques, tufted astrocytes and argyrophilic grains were all argyrophilic. Pick bodies showed tau and ubiquitin immunoreactivity. However, Globous NFTs, astrocytic plaques, tufted astrocytes, and argyrophilic grains were reactive only to tau immunohistochemistry.

CONCLUSIONSFindings of characteristic neuronal and glial inclusions may help to differentiate non-Alzheimer type dementia from AD, and in conjunction with Gallyas-Braak staining and immunohistochemistry for tau and ubiquitin, to further define histopathologic subcategories of non-Alzheimer type dementia.

OBJECTIVETo explore the expression of Cysleine-rich 61(Cyr61) gene in the different subtypes of myelodysplastic syndromes (MDS), and the significance of Cyr61 in the genesis progression, and transformation of MDS and the relationship between Cyr61 and vascular endothelial grown factor (VEGF).

METHODSReverse transcriptase-polymerase chain reaction (RT-PCR) and immunohistochemical S-P were used to detect mRNA and protein expressions of Cyr61 and VEGF in bone marrow mononuclear cells (BMMNC) from 28 MDS, 12 acute myeloid leukemia (AML) patients, and 10 normal volunteers.

RESULTSExpressions of Cyr61 and VEGF were higher in MDS and AML patients than in controls (P < 0.05). The expressions of Cyr61 and VEGF were significantly higher in high risk group (0.3998 +/- 0.2647, 0.4775 +/- 0.1342) than that in low risk MDS group (0.2213 +/- 0.1465, 0.2872 +/- 0.2341) (P < 0.05), but no significant difference between high risk MDS and AML patients. Expressions of Cyr61 and VEGF protein were higher in MDS patients than in normal controls (P < 0.05), and were significantly higher in high risk MDS group \[(38.7 +/- 2.9)%, (43.2 +/- 2.7)%\] than in low risk group \[(31.4 +/- 3.1)%, (33.5 +/- 3.4)%\] (P < 0.05). Expressions of Cyr61 and VEGF were significantly correlated (r = 0.8762, P < 0.01).

CONCLUSIONCyr61 and VEGF may play a role in the angiogenesis and pathogenesis of MDS.

OBJECTIVETo prepare a time-resolved fluoroimmunoassay (TRFIA) kit for clinical detection of IgM antibodies to hepatitis B core antigen (HBc).

METHODSImmunocapture method was used to develop the TRFIA kit for detection of the anti-HBc IgM antibodies, and the precision, cross-reactivity and sensitivity of the kit were tested with the clinical serum samples.

RESULTSThe intra- and inter-assay coefficients of variation of the TRFIA kit were 4.8%-7.2% and 7.5%-8.6%, respectively, and no cross-reactivity with anti-HBs, anti-HBc-IgG or anti-HBe was found. Comparison of the results of the TRFIA kit and enzyme-linked immunosorbent assay (ELISA) demonstrated greater sensitivity of the kit than ELISA in detecting the anti-HBc IgM antibodies in 584 serum samples. According to the detection results in 300 serum samples from healthy donors, the cutoff value of the TRFIA kit was 4.5 times of the fluorescence value of the negative control.

CONCLUSIONThis TRFIA kit for detecting anti-HBc IgM antibodies meets the demand for clinical application and can replace the ELISA kits.
