ObjectiveTo study the effect of isoflavones from Sojae Semen Praeparatum (ISSP) on lipid metabolism in atherosclerotic mice, and decipher the underlying mechanism via the peroxisome proliferator-activated receptor gamma/liver X receptor alpha/ATP-binding cassette transporter A1 (PPARγ/LXRα/ABCA1) signaling pathway. MethodFifty ApoE-/- mice were randomly assigned into the model group, western medicine (atorvastatin calcium, 3.03 mg·kg-1) group, and low-, medium-, and high-dose ISSP (2.5, 5, 10 mg·kg-1, respectively) groups, with 10 rats in each group. Atherosclerosis model mice were established by bilateral ovariectomy and feeding high-fat diet. Another 10 ApoE-/- mice receiving ovariectomy and high-fat diet were taken as the sham group. Some mice died of postoperative infection, and finally 6 mice were included in each group. One week after operation, each group was administrated with corresponding drugs or equivalent amount of normal saline. After 12 weeks, the levels of triglyceride (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and non-esterified fatty acids (NEFAs) in serum and liver tissue were measured. The levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in serum were detected by enzyme-linked immunosorbent assay (ELISA). Hematoxylin-eosin (HE) staining and oil red O staining were used for observation of aortic plaque formation and liver lipid deposition. The mRNA and protein levels of PPARγ, LXRα, ABCA1, and ATP-binding cassette transporter G1 (ABCG1) in liver were determined by real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) and Western blot. ResultCompared with the sham group, the modeling of atherosclerosis increased the aortic plaque area (P<0.01), elevated the serum TC, TG, LDL-C, TNF-α, and IL-6 levels (P<0.01), decreased the level of HDL-C (P<0.01), increased the liver index (P<0.05) and the levels of TC, TG, and NEFAs in liver (P<0.01), and caused obvious hepatic fat vacuoles and lipid deposition. In addition, the modeling down-regulated the mRNA levels of PPARγ, LXRα, ABCA1 in liver (P<0.05, P<0.01),and regulated the mRNA and protein levels of ABCG1(P<0.05, P<0.01). Compared with the model group, atorvastatin calcium and middle-, high-dose ISSP reduced the serum TC, TG, LDL-C, TNF-α, and IL-6 levels (P<0.01), decreased the liver index (P<0.01), alleviated the liver fat vacuoles and lipid deposition, and increased the levels of TC, TG, and NEFAs in the liver (P<0.05, P<0.01). Furthermore, they up-regulated the mRNA and protein levels of PPARγ, LXRα, ABCA1, and ABCG1 in the liver (P<0.05, P<0.01). ConclusionISSP may regulate lipid metabolism through PPARγ/LXRα/ABCA1 signaling pathway to down-regulate the expression of inflammatory cytokines in serum and alleviate liver lipid deposition, thereby suppressing the formation of atherosclerotic plaque.

Atractylodis Rhizoma(AR) is a traditional Chinese medicinal material for food and medicine, with the functions of eli-minating dampness, strengthening the spleen, expelling wind evil and dispersing cold. AR contains a variety of compounds, including sesquiterpenoids, alkynes, triterpenoids, aromatic glycosides, polysaccharides and so on. At present, the researches on AR mainly focus on volatile components, with relatively fewer researches on non-volatile components. Polysaccharide from Atractylodis Rhizoma(ARP) is an important material basis among non-volatile components for the efficacy. Due to its many biological activities such as immunomodulatory activity, anti-tumors, anti-virus and anti-oxidation, ARP has certain research value and potential. The diversity of the polysaccharide structure is the basis for biological functions, but it also increases the difficulty of carbohydrate research. The research on the extraction, separation, purification, structure and activity of ARP is in the preliminary exploration stage, still with many shortcomings. Herein, recent advancements in the extraction, purification, structural characteristics and biological activities of ARP were summarized in this article to provide scientific reference for the in-depth systematic research of ARP and the development of AR resources.

OBJECTIVETo investigate the effects of glucocorticoid receptor antagonist-M8046 on the behavior and the cyclooxygenase-2/prostaglandin E2( COX-2/PGE2) expression in spinal cord dorsal horn and dorsal root ganglia (DRG) in chronic constrictive injury (CCI) rats.
METHODSOne hundred and forty-four male SD rats were randomly divided into 4 groups, 36 rats in each group: Sham operation group (Sham), chronic constrictive group (CCI), M8046 treated group (M8046) and solvent controlled group (Sc). M8046 3 mg/(kg x d) intraperitoneal injection was given after operation in group M8046. Paw thennal withdrawal (PTWL) and paw mechanical withdrawal threshold (PMWT) of rats were measured on 2 pre-operative and 1, 3, 7, 10, 14 post-operative days. The spinal cord and L15 DRG of the operated side was removed at 3, 7, 14 days after surgery. The change of COX-2 and PGE2 expression was determined by immunohistochemical staining and ELISA separately.
RESULTSPTWL and PMWT in CCI group were significantly lower than those in Sham group on every post-operative day (P < 0.05). PTWL and PMWT in M8046 group were significantly higher than those in CCI group on 7, 10, 14 post-operative day (P < 0.05). In spinal dorsal horn, the level of COX-2 and PGE2 expression in CCI group was significantly higher than that in Sham group (P < 0.05). M8046 could significantly attenuate the activation of COX-2 and PGE2 induced by CCI (P < 0.05). The expression of COX-2 and PGE2 in DRG was similar to that in spinal dorsal horn.
CONCLUSIONThe effects of M8046 ameliorate the CCI-induced neuropathic pain may be related to attenuate the expression of COX-2 and PGE2 in spinal cord and DRG.

OBJECTIVETo investigate the status of the clinical agency of detection, management, and health insurance for hypertensive patients in urban and rural communities of five provinces in China in 2010, in order to provide fundamental data for implementation and evaluation of community health management of hypertensive patients in basic public health service.
METHODSFrom Jiangsu, Shandong, Hebei, Sichuan and Gansu provinces, cities and districts (counties) were selected according to economic development level and 10 survey sites were finally determined. In each survey site, 3-4 communities or townships were selected by cluster sampling methods in 2010. A total of 8326 eligible hypertensive patients (4363 in urban and 3963 in rural) were included. The urban-rural difference of clinical agency and health insurance was compared for hypertensive patients.
RESULTSIn urban areas, 43.74% (1867/4268) hypertensive patients were first diagnosed at hospitals of district level or above, 25.07% (1070/4268) at community health service centers (CHSC), and 20.20% (862/4268) at community health service stations (CHSS), respectively; 30.72% (1274/4147) and 31.11% (1290/4147) patients chose CHSC and CHSS for their follow-up visiting, respectively; 60.23% (3073/5102) antihypertensive medication was obtained from pharmacies. In rural areas, 54.58% (2133/3908) hypertensive patients were first diagnosed at village clinics, 22.36% (874/3908) at township hospitals, and 18.86% (737/3908) at hospitals of county level or above; 70.49% (2695/3823) patients chose village clinics for their follow-up visiting; 46.23% (2116/4577) antihypertensive medication was obtained from village clinics, and 36.29% (1661/4577) from pharmacies. The main reasons for choosing clinical agency for both urban and rural patients were convenience (45.79%, 6276/13 706) and low cost (11.78%, 1614/13 706). The proportions of reimbursements for hospitalization expenses and total medical expenses for hypertensive patients in urban in the past year were 66.67% and 34.78%, respectively, which were much higher than those in rural (35.71% and 9.50%) (Z value was -12.13 and -17.56, P < 0.01).
CONCLUSIONCommunity-based hypertension detection and routine blood pressure measurement during clinical visiting should be further strengthened to improve early diagnosis of hypertension. The development of community-based clinical agency should be able to provide convenient and low cost health service for hypertensive patients to improve treatment, follow-up and control of hypertension.
