Objective:The research aimed to figure out the geographic availability of the residence in the aspect of receiving health service thereby studying the spatial distribution regulation and the distance attenuation coefficient of the inpatients.It also provides the decision-making basis for the regional health planning.Methods: Select 23 medical institutions and randomly pick up patients from each of them, calculate the distance between the inpatients home and the medical institutions, then simulate the corresponding probability patients using the Geographical Infor-mation System ( GIS) .Perform a variety of curve fitting models according to the determination and simulation graph-ics coefficient choosing the most appropriate model, and draw corresponding the distance attenuation coefficient.Re-sults:An exponential curve model is better than power curve model for the secondary medical institutions inpatients distribution and contrarily for those in the tertiary medical institutions.The mean distance attenuation coefficient was 0.51 for exponential curve model of secondary comprehensive medical institutions inpatients and its average was 0.50 for the secondary specialist medical institutions inpatients.The mean distance attenuation coefficient was 0.84 for the power curve model of the tertiary comprehensive medical institutions inpatient and its average was 0.53 for tertiary specialist medical institutions inpatients.Conclusion: The secondary medical institutions inpatient probable attenua-tion trends with distance are faster than in tertiary medical institutions, those for the comprehensive medical institu-tions inpatient are faster than in the specialist medical institutions.In the regional health planning, for different lev-els, categories of medical institutions should adopt different distance attenuation coefficients to calculate the health re-sources level.

OBJECTIVETo obtain 20(S)-ginsenoside Rh1 by the method of enzymolysis with the protopananxtriol saponins, and to provide the theory for large-scale preparation of 20(S)-ginsenoside Rh1.
METHODAB-8 macroporous resin was used to isolate the total saponins of the stems and leaves from Panax ginseng and the protopanaxtriol saponins (mainly included Rg1 and Re) were obtained. Then, we used enzymic hydrolysis (helicase) with the protopanaxtriol saponins to get the secondary ginsenoside 20(S)-Rh1. High performance liquid chromatography analysis method was established to determine the conversion with the YMC C18 column at the 25 degrees C. The flow rate was 1 mL x min(-1) and detective wavelength was 203 nm. The mobile phase consisted of acetonitrile(A)-water(B) was eluted by the way of 0-29 min,19%-26% A, 29-30 min, 26%-30% A, 30-55 min, 30%-38% A, 55-60 min, 38%-40% A.
RESULTHighly purified protopanaxtriol saponins were obtained through AB-8 macroporous resin. The average conversion was 36.7%. The method was simple and stable.
CONCLUSIONThe method is able to obtain secondary ginsenoside 20 (S)-Rh1 with high efficiency. This study develop the preparation resource for the ginsenoside 20(S)-Rh1.

OBJECTIVETo describe the transvenous catheterization technique for the treatment of cavernous sinus dural arteriovenous fistulas (CSdAVFs), including its indications, complications and efficacy.
METHODSEight patients with symptomatic CSdAVFs were treated by endovascular embolization with platinum coils, via the inferior petrosal sinus (IPS) in 6 patients, and via the Sylvian vein after surgical exposure in other 2 patients.
RESULTSComplete angiographic resolution of the fistula was obtained in six patients immediately after the procedures, and a complete resolution of symptoms and signs was achieved in all patients. The residual fistulas in two patients disappeared completely in the follow-up angiography.
CONCLUSIONTransvenous embolization is a useful and safe approach in the management of CSdAVFs.

Objective:To investigate the effect of tripartite motif-containing protein 59 (TRIM59) on glucose metabolism in macrophages and its role in regulating hypoxia-inducible factor-1α (HIF-1α)/IL-10 axis in macrophages under inflammatory conditions.Methods:The differentially expressed genes between macrophages with high expression of TRIM59 and control cells transfected with empty TRIM59 plasmid were analyzed by GO and KEGG. The expression of HIF-1α by RAW264.7 macrophages with high expression of TRIM59 was detected at different time points after lipopolysaccharide (LPS) stimulation by RT-qPCR and Western blot. Bone marrow was isolated from TRIM59-cKO and TRIM59 flox/flox mice and induced to differentiate into bone marrow-derived macrophages (BMDMs). These BMDMs were stimulated with LPS and the supernatants of cell culture were collected at 3, 6, 12 and 24 h after stimulation to detect IL-10 level by ELISA. In addition, mouse models of cecal ligation and puncture (CLP) were established, and bronchoalveolar lavage fluid (BALF) samples were collected at the same time points to detect IL-10 level by ELISA. Histopathological changes in lung tissues were observed after HE staining. Results:There was a significant change in glucose metabolism-related genes in macrophages with high expression of TRIM59, and the content of lactic acid increased significantly. Compared with the control group, the expression of HIF-1α at mRNA level in BMDMs from TRIM59-cKO mice decreased after LPS stimulation ( P<0.05); the level of IL-10 increased at 3 h and 24 h in the TRIM59-cKO group, but there was no significant difference in IL-10 level at 6 h or 12 h between the two groups. In the TRIM59-cKO mouse model of CLP, the levels of IL-10 in the BALF samples increased with time, but decreased at 24 h. The level of IL-10 was higher in the TRIM59-cKO mouse model group than that in the control group at each time point ( P<0.05 or P<0.01). Conclusions:TRIM59 can inhibit inflammation and lung injury by decreasing HIF-1α-mediated lactate secretion and IL-10 expression in macrophages. This study provides a new idea for developing novel anti-sepsis drugs based on TRIM59.

ObjectiveTo observe the effects of Cuscutae Semen on the learning and memory ability, N6-methyladenosine (m6A)-related modification enzymes and total m6A level in hippocampus of the offspring of fear-damaged pregnant rats. MethodForty-five pregnant rats were randomly divided into blank group, model group and Cuscutae Semen group. From the 1st day to the 19th day of pregnancy, rats in the model group and the Cuscutae Semen group were induced by observing electric shock of other rats. The Cuscutae Semen group was treated with 5 g·kg-1·d-1 Cuscutae Semen decoction (ig), while the other two groups were treated with the same amount of purified water. The offspring were assigned following the grouping method of their maternal generation. The behavioral changes of the offspring were tested by Morris water maze on 21st day after birth, and the development of hippocampal neurons was observed by transmission electron microscopy. The mRNA and protein expression levels of methyltransferase-like 3 (METTL3), METTL14, Wilms tumor 1 associated protein (WTAP), fat mass and obesity-associated protein (FTO) and Alk B homologue 5 (ALKBH5) were detected by Real-time polymerase chain reaction (Real-time PCR), Western blot and immunohistochemistry (IHC). The total content of m6A in hippocampus was determined by high performance liquid chromatography tandem mass spectrometry (LC-MS/MS). ResultCompared with the conditions in the blank group, the average latency duration in the model group was prolonged, and the number of entries in the target quadrant, the target quadrant duration and the number of crossing the platform were decreased (P<0.01). Additionally, the model group had seriously damaged structure of hippocampal CA1 and CA3 neurons, swollen mitochondria, expanded endoplasmic reticulum, and small number of synapses with some having blurred structure, and the expression levels of METTL3, METTL14, FTO, ALKBH5 as well as the total m6A level were lower than those in the blank group (P<0.05,P<0.01). Compared with the model group, the Cuscutae Semen group had shortened average latency duration, increased number of entries in the target quadrant, target quadrant duration and number of crossing the platform (P<0.01), alleviated damage of hippocampal CA1 and CA3 neurons, fine structure of mitochondrial and endoplasmic reticulum, and clear, intact and dense synapses. And the expression levels of METTL3, METTL14, FTO as well as the total level of m6A were up regulated, while the expression level of ALKBH5 was down regulated in the Cuscutae Semen group (P<0.05,P<0.01). ConclusionCuscutae Semen improved the learning and memory ability of the offspring of the rats affected by fear damaging kidney during pregnancy, protected hippocampal neurons, and up-regulated the expression levels of METTL3, METTL14, FTO and the total m6A level in hippocampus.
