This paper designed an index for the differences in medical service prices and this index therein named the Hospital Price Difference Index ( HPDI) which is used as a quantitative tool for evaluation. During evalua-tion, the paper measured the levels of prices and the factors of influence in 18 public hospitals listed in the Sichuan Province. The results showed that the effect of regulating the levels of prices was reasonable and effective, but was sig-nificantly affected by the internal and external factors. The internal factors have been found to be the medical and clini-cal technologies, and the grade and scale acted as external ones. This paper suggested that the price department should pay more attention on the levels of prices, and hence made a reasonable reform project for the prices by taking the scale of adjustment of prices into account.

Objective:To investigate the incidence of asthma and the characteristics of acute attacks in children aged 3-14 in different administrative areas of Wuxi, and to analyze the correlation of asthma with the outdoor environmental factors.Methods:A total of 10 175 children aged 3-14 were randomly selected from 5 different administrative regions in Wuxi City, Jiangsu Province for childhood asthma epidemiological survey from January to December in 2017.Results:The complete questionnaires were collected from 8 318 children with a response rate of 81.70%.There were 6 734 valid questionnaires.Asthma occurred to 259 children, and the prevalence rate was 3.84%.The prevalence of asthma in male and female children was 4.89% (163 cases) and 2.82% (96 cases), respectively.The ratio of male patients to female patients was 1.70∶1.00, and the difference was significant ( χ2=19.72, P<0.01). Children were most prone to suffer from asthma attacks at the turn of seasons (87/259 cases, 33.59%). The frequency of asthma was the lowest from June to August (9/259 cases, 3.47%). Among 244 cases attacked by acute asthma, the prevailing time period of acute attacks was irregular in 88 patients (36.07%), bedtime in 64 cases (26.23%). In different regions of the city, the lowest prevalence rate of asthma was found in Binhu District (50/1 830 cases, 2.73%), the highest prevalence rate of asthma was found in Xinwu District (71/1 502 cases, 4.72%), the difference between the highest and lowest prevalence rates of asthma was significant ( χ2=13.19, P<0.05). In terms of the air quality in different admi-nistrative regions of Wuxi, the nitrogen dioxide (NO 2) concentration, the carbon monoxide (CO) concentration, PM 10 and PM 2.5 in Binhu District were lower than other 4 regions.In different seasons in Wuxi city, the sulfur dioxide(SO 2) concentration, the NO 2 concentration, the CO concentration, PM 10 and PM 2.5 from June to August were significantly lower than those in other months.The prevalence of asthma in children in different administrative districts of Wuxi was weakly positively correlated with the SO 2 concentration, the NO 2 concentration and PM 10 ( r=0.10, P<0.01; r=0.22, P<0.01; r=0.06, P<0.01, respectively). The prevalence of asthma was weakly negatively associated with the ozone(O 3) concentration ( r=-0.06, P<0.01). Acute asthma attacks were weakly positively correlated with the SO 2 concentration ( r=0.22, P<0.01), the NO 2 concentration ( r=0.28, P<0.01), the CO concentration ( r=0.23, P<0.01), PM 10 ( r=0.18, P<0.01) and PM 2.5 ( r=0.18, P<0.01), and weakly negatively correlated with the O 3 concentration ( r=-0.40, P<0.01). Conclusions:The prevalence of asthma in Wuxi is higher in boys than in girls, and the frequency of asthma attacks is related to the season.The SO 2, NO 2, CO, PM 10, PM 2.5 and O 3 concentration affect the prevalence and acute attacks of asthma.

The dynamic changes of germination percentage, germination potential, thousand-seed weight, antioxidase activity in Desmodium styracifolium seeds with different storage time were tested, and electrical conductivity, contents of soluble sugar, soluble protein, starch in seed leach liquor were also determined in order to reveal the mechanism of seed deterioration. The results as the following. (1) The germination percentage, germination potential and thousand-seed weight of D. styracifolium seeds declined, while the seed coat color darkened with the extension of storage time. (2) The activities of superoxide dismutase (SOD) and peroxidase (POD) decreased with the prolongation of storage period. The SOD activity declined fastest in 1,095-1,185 d of storage, while the POD activity declined significantly in 365-395 d of storage. (3) The electrical conductivity and the contents of soluble sugar, starch in seed leach liquor increased, while the content of soluble protein declined with the extension of storage time. (4) Correlation analysis indicated that the germination percentage, germination potential and thousand-seed weight of D. styracifolium seeds have a significantly positive correlation with SOD and POD activity, while have a significantly negative correlation with the electrical conductivity, contents of soluble sugar and starch. It can be concluded that during the storage of D. styracifolium seeds, physiological and biochemical changes including decrease in antioxidase activity, rise in electrical conductivity, degradation effluent of soluble sugar and starch, degradation of soluble protein were the main factors leading to the seed deterioration.

The metabonomics method was used to study the intervention effect of Psoraleae Fructus and Myristicae Semen in "Ershen pill" on the changes in serum endogenous metabolites in spleen-kidney Yang deficiency diarrhea rats before and after processing, screen out differentiated metabolites related to spleen-kidney Yang deficiency diarrhea and explore the metabolic patterns related to spleen-kidney Yang deficiency diarrhea and the processing synergy mechanism of Psoraleae Fructus and Myristicae Semen in "Ershen pill". Efforts were made to detect SOD and MDA of each group, test rat serum metabolic fingerprints in different stages by using GC-MS, analyze by PCA and PLS-DA methods and screen out potential biomarks through VIP and t test. The results revealed that "Ershen pill" could enhance the level of SOD and decrease the level of MDA and identified 10 differentiated metabolites related to spleen-kidney Yang deficiency diarrhea. Compared with the model group, all of metabolites recovered to varying levels after being intervened with "Ershen pill", with the best effect shown in the "Ershen pill" IV group (salt-processed Psoraleae Fructus + bran-roasted Myristicae Semen). It is speculated that that Psoraleae Fructus and Semen Myristicae in "Ershen pill" show a synergistic effect by inhibiting peroxide, improving aglucolipid, amino acids and energy metabolism, with multiple target sites.

Objective To evaluate the accuracy of renal scintigraphy for the estimation of glomerular filtration rates (dGFR) in patients with diabetic nephropathy as compared to the conventional dual-plasma sample clearance method (pscGFR). Methods Forty-six patients with diabetic nephropathy underwent both dynamic renal scintigraphy and dual-plasma sample measurement after 99Tcm-DTPA injection. Paired student t-test and correlation analysis were performed to compare dGFR and pscGFR (normalized to body surface area,1.73 m-2). Results The mean dGFR was higher than mean pscGFR ((51.08±26.78)ml·min-1vs (44.06±29.43)ml·min-1,t=4.209,P=0.000). The dGFR correlated with pscGFR ( r=0.923,P=0.000) linearly (regression equation:pscGFR=1.015×dGFR-7.773,F=254. 656,P=0.000).Conclusions dGFR correlated well with pscGFR. Although it could not absolutely replace the latter in patients with diabetic nephropathy,dGFR could reasonably evaluate the filtration function for these patients.

OBJECTIVETo detect Porphyromonas gingivalis (P. gingivalis) in buccal epithelial cells and subgingival plaque from periodontally healthy subjects and patients with chronic periodontitis.

METHODS40 subjects were included in the healthy group and 39 subjects were included in the diseased group in this study. Cells and subgingival plaque samples were collected. The extracted DNA was amplified with universal primers and P. gingivalis species-specific primer.

RESULTSP. gingivalis was detected in 37.5% of subgingival plaque samples and 32.5% of buccal mucosa samples in the healthy subjects, but 69.23% of subgingival plaque samples and 46.15% of buccal mucosa samples in the periodontitis group. Highly statistically significant differences were observed between healthy and periodontitis groups in the detections of P. gingivalis of subgingival plaque samples.

CONCLUSIONP. gingivalis may be one of oral flora because it can be detected in the healthy population and not lead to destruction of supporting structures of the teeth.

OBJECTIVETo construct a three plasmids lentiviral vector containing canine coagulation factor IX (cFIX) gene with ubiquinone promoter (PUB) and observe the expression of cFIX gene.

METHODSLentivirus was generated by transient three-plasmid transfection, namely, the VSV-G envelope expression cassette, the delta NRF packaging plasmid and the PTK 164 plasmid. Viral particles were used to infect the target cell, third passage mesenchymal stem cells (MSCs) and 293T cell respectively at MOI 3: 1. The cFIX activity was detected in cultured cells with one-stage clotting assay.

RESULTSThe MSCs were obtained in vitro. The lentivirus infected MSCs and 293T cells all expressed the active factor IX with the activity of (26.30 +/- 2.10)% and (19.70 +/- 1.53)%, respectively, which are significantly higher than that of control (1.00 +/- 0.05)%.

CONCLUSIONSThe lentiviral vector of three plasmids with ubiquinone promoter (PUB) was constructed and can transfect the MSCs and 293T cells.
