Purpose:Taking tuberculosis as an example, this paper aims at to analyzing the level of reimburse-ment for infectious diseases care, and clarifying the government responsibility. Methods:In order to achieve the ob-jective of this research, UHC framework was used to analyze the security level. Result:The findings of this research reveal that TB in-patients' Compensation Ratio of the New Cooperative Medical Scheme ( NCMS) was lower than aver-age level of all the NCMS patients, the out-patients' was even lower. The categories of anti-tuberculotic for free was limited, the utilization was not as expected. Medical assistance covered few people in spite of its high level of reim-bursement. Conclusion:Based on the findings of this review, it has been revealed that the medical insurance didn't make a big difference in financial protection for patients with infectious diseases. As the treatment for of infectious diseases is a quasi-public good, the government has to shoulder the responsibility of improving the compensation ratio of the patients.

In order to identify Aucklandiae Radix, Vladimiriae Radix, Inulae Radix, Aristolochiae Radix and Kadsurae Radix using ITS2 barcodes, genomic DNA from sixty samples was extracted and the ITS2 (internal transcribed spacer) regions were amplified and sequenced. The genetic distances were computed using MEGA 5.0 in accordance with the kimura 2-parameter (K2P) model and the neighbor-joining (NJ) phylogenetic tree was constructed. The results indicated that for Aucklandiae Radix (Aucklandia lappa), Vladimiriae Radix (Vladimiria souliei and V. souliei var. cinerea), Inulae Radix (Inula helenium), Aristolochiae Radix (Aristolochia debilis) and Kadsurae Radix (Kadsura longipedunculata), the intra-specific variation was smaller than inter-specific one. There are 162 variable sites among 272 bp after alignment of all ITS2 sequence haplotypes. For each species, the intra-specific genetic distances were also smaller than inter-specific one. Furthermore, the NJ tree strongly supported that Aucklandiae Radix, Vladimiriae Radix, Inulae Radix, Aristolochiae Radix and Kadsurae Radix can be differentiated. At the same time, V. souliei (Dolomiaea souliei) and V. souliei var. cinerea( D. souliei var. cinerea) belonging to Vladimiriae Radix were clearly identified. In conclusion, ITS2 barcode could be used to identify Aucklandiae Radix, Vladimiriae Radix, Inulae Radix, Aristolochiae Radix and Kadsurae Radix. Our study may provide a scientific foundation for clinical safe use of the traditional Chinese medicines.

Objective To determine the effect of fibroblast growth factor (FGF) on endothelia cell (EC) proliferation in vitro,TNP-470 and dexamethasone (Dex) and explore the possible mechanisms of FGF stimulating EC proliferation. Methods Cultured human umbilical vein endothelial cell (HUVEC) was divided into two groups: control group (Group DMEM) and experimental groups (Group FGF,Group Dex,Group TNP-470,Group FGF+Dex,Group FGF+TNP-470). The EC proliferation was quantified by a colorimetric assay using MTT reagent,the relative cell numbers at every time point of EC cycle analyzed with flow cytometer,and the expression of nuclear factor-kappa B p65 (NF-?B p65) and ki-67 detected with immunohistochemical method of SABC. Results FGF stimulated significantly EC proliferation,raised proliferation index (PI) and enhanced the expressions of NF-?B p65 and ki-67 in nuclear. TNP-470 reduced PI and TNP-470 and Dex suppressed EC proliferation and finally decreased the expressions of NF-?B p65 and ki-67 in nuclear. FGF could facilitate the inhibitory effect of TNP-470 and Dex. Conclusions The possible mechanism of EC proliferation stimulated by FGF is that FGF can activate NF-?B to promote the synthesis of DNA and EC mitosis. TNP-470 and Dex suppress proliferation and differentiation of EC but FGF may reverse such suppressive effect.

The direct acting substances of Cuscuta chinensis in vivo were preliminarily identified through the correlation analysis of "metabolites-effect identification" model. The ovariectomized female rats were i.g administered with 95% ethanol extract part, 40% ethanol elution part and n-butanol extract part of Cuscuta chinensis. The serum fingerprints of different parts and times of administration were established by UPLC/Q-TOF-MS. At the same time, serum estradiol (E₂), follicle-stimulating hormone (FSH) and luteinizing hormone (LH) levels were detected. Bivariate correlation analysis and grey correlation analysis were used to screen estrogenic components. The results showed that nine direct acting substances in vivo highly related to estrogen effect were found in the drug containing serum, which were hyperoside, astragalin, methyl quercetin glucuronide, quercetin-diglucuronide, quercetin, apigenin, isoquercitrin, kaempferol glucuronide and kaempferol. We can preliminarily screen out the direct acting substance of estrogen effect of Cuscuta chinensis in vivo based on the research idea of serum spectrum effect correlation. It provides a reliable basis for revealing the estrogeneffective substances of Cuscuta chinensis and confirming the quality markers. This experiment was approved by Harbin University of Commerce Ethics Committees (Approval No. HSDU2020-065).

In order to explore the effect and underlying mechanism of hypoxia on body weight, the effect of intermittent moderate hypoxia on high-fat diet-induced obesity was observed in mice, and the role of leptin in hypoxic effect was identified. Healthy Kunming mice were divided randomly into 4 groups (n=20 in each group). The control group: the mice were fed normally under the normal oxygen pressure. Hypoxia group: the mice were fed normally, and given intermittent moderate hypoxia training. Obesity group: the mice were fed diet rich in fat and sugar under the normal oxygen pressure. Hypoxia + obesity group: the mice were fed diet rich in fat and sugar, and given intermittent moderate hypoxia training. After 40 d of feeding and training, the body weight of mice was determined, and the average increasing rate of body weight in each group was calculated and normalized with food intake. Meanwhile, plasma leptin level was measured with ELISA method, and fatty degeneration and leptin receptor expression in liver were observed by Sudan III staining and immunohistochemistry, respectively. The obesity mouse model was successfully established with increases in body weight, plasma leptin level and distribution of adipocytes in the liver. The average body weight and density of adipocytes in the liver in hypoxia and hypoxia + obesity groups decreased obviously, while plasma leptin level and leptin receptor expression in the liver were increased. It is suggested that intermittent moderate hypoxia reduces body weight through elevating plasma leptin level and/or enhancing leptin receptor expression in the liver.

GM1 gangliosidosis is an autosomal recessive disorder caused by galactosidase beta1 (GLB1) gene variants which affect the activity of β-galactosidase (GLB). GLB dysfunction causes abnormalities in the degradation of GM1 and its accumulation in lysosome. This article reports the clinical and genetic features of a child with GM1 gangliosidosis. The girl, aged 2 years and 5 months, was referred to the hospital due to motor developmental regression for more than one year. Physical examination showed binocular deflection and horizontal nystagmus, but no abnormality was found on fundoscopy. The girl had increased muscular tone of the extremities, limitation of motion of the elbow, knee, and ankle joints, and hyperactive patellar tendon reflex. Blood biochemical examination showed a significant increase in aspartate aminotransferase. The 24-hour electroencephalographic monitoring detected frequent seizure attacks and diffuse θ wave activity, especially in the right hemisphere. Head magnetic resonance imaging showed thinner white matter in the periventricular region and diffuse high T2WI signal with unclear boundary. Three-dimensional reconstruction of white matter fiber tracts by diffusion tensor imaging showed smaller and thinner white matter fiber tracts, especially in the right hemisphere. Genetic analysis showed that the girl had compound heterozygous mutations of c.446C>T (p.Ser149Phe) and c.101T>C (p.Ile34Thr) in the GLB1 gene from her parents, among which c.101T>C (p.Ile34Thr) had not been reported in the literatures. The girl was finally diagnosed with GM1 gangliosidosis. Her conditions were not improved after antiepileptic treatment and rehabilitation training for 2 months.

BACKGROUNDThe aim of this study was to assess the performance of apparent diffusion coefficient (ADC) measurement obtained with diffusion-weighted magnetic resonance imaging (DW-MRI) to distinguish renal cell carcinomas (RCCs) from small benign solid renal tumors (≤ 4 cm).

METHODSIn this cross-sectional study, 49 consecutive patients with histopathologically confirmed small solid renal tumors, and seven healthy volunteers were imaged using nonenhanced MRI and DW-MRI. The ADC map was calculated using the b values of 0, 50, 400, and 600 s/mm 2 and values compared via the Kruskal-Wallis and Mann-Whitney tests. The utility of ADC for differentiating RCCs and benign lesions was assessed using a receiver operating characteristic curve. Multiple nonenhanced MRI features were analyzed by Logistic regression.

RESULTSThe tumors consisted of 33 cases of clear-cell RCCs (ccRCCs) and 16 cases of benign tumors, including 14 cases of minimal fat angiomyolipomas and 2 cases of oncocytomas. The ADCs showed significant differences among benign tumors ([0.90 ± 0.52] × 10-3 mm 2 /s), ccRCCs ([1.53 ± 0.31] × 10-3 mm 2 /s) and the normal renal parenchyma ([2.22 ± 0.12] × 10-3 mm 2 /s) (P < 0.001). Moreover, there was statistically significant difference between high and low-grade ccRCCs (P = 0.004). Using a cut-off ADC of 1.36 × 10-3 mm 2 /s, DW-MRI resulted in an area under the curve (AUC), sensitivity, and specificity equal to 0.839, 75.8%, and 87.5%, respectively. Nonenhanced MRI alone and the combination of imaging methods led to an AUC, sensitivity and specificity equal to 0.919, 93.9%, and 81.2%, 0.998, 97%, and 100%, respectively. The Logistic regression showed that the location of the center of the tumor (inside the contour of the kidney) and appearance of stiff blood vessel were significantly helpful for diagnosing ccRCCs.

CONCLUSIONSDW-MRI has potential in distinguishing ccRCCs from benign lesions in human small solid renal tumors (≤ 4 cm), and in increasing the accuracy for diagnosing ccRCCs when combined with nonenhanced MRI.
