Objective To study the expression of liver X receptor (LXR) during the progress of multiple organ dysfunction syndrome (MODS) caused by wound infection, and its role in the lipid metabolism during MODS. Method The MODS models caused by wound infection were produced. One hundred Wistar rats were randomly divided into wound group (group T, n = 30) and MODS caused by wound infection group (group M, n = SO). The closed multi-fracture and extensive soft-tissue injury was produced in rats using jaw. After 12 hours, a thirty percent total body surface area Ⅲ (TBSA Ⅲ ) bum was induced in group M,and the rats were contaminated by pseudomonas aeruginosa. The levels of endotoxin ( LPS), alanine transaminase (ALT), free fatty acid ( FFA), TG, HDL, VLDL were determined before injuries and post injuries 24, 48, 96, 120 hours, and at each time point in each group, only 10 rats were determined. And at the same tune, real-time quantitative reverse transcription polymerase chain reaction technique was used to measure the gene expression of LXR. Chi-square test was used. Results The blood ALT and LPS levels in rats were increased slowly, the levels of FFA reached peak at 96 hours post injuries (P ＜ 0.05), the level of TG increased first and then decreased to the lowest at 96 hours, HDL dropped slowly, and VLDL decreased first and then increased. The gene expression of LXR increased slightly at 24 hours and then gradually decreased in group T, and the gene expression of LXR decreased more obviously in group M, and there was significant difference compared with group T. Conclusions ALT increased slowly, and was positively correlated with IPS post injuries. This indicated that infection aggravated the liver injury. The gene expression of LXRα increased in the early stage and then decreased in the late stage, LPS and LXRα were negatively correlated, which may cause the change of LXRα. The decreased expression of LXRα during MODS may contribute to dysfunction of cholesterol transport and fatty acid synthesis.

Objective To investigate the relationship between anti-trophoblast membrane antigens(TA) antibodies and hypertensive disorders complicating pregnancy(HDCP).Methods Enzyme linked immunosorbent assay(ELISA) was used to detect anti-TA IgG and IgM in both maternal and umbilical serum samples of 40 normal pregnant women and 92 HDCP women(23 gestational hypertension or mild preeclampsia,41 severe preeclampsia and 28 eclampsia).Results The positive rates of anti-TA IgG and IgM in maternal serum samples with HDCP,eclampsia or severe preeclampsia were significantly higher than that in normal pregnant women,the positive rate of anti-TA IgM increased significantly with the aggravation of HDCP(P

Objective To study the effect of Xuebijing injection on the change of intestinal tract mucosa barriers and the expression of macrophage antihody in rats with sepsis. Method Totally 150 Wistar rats were ran-domly divided into three groups: sham group, sepsis group, and Xuebijing group. Sepsis models were estabhshed in rats by cecal ligation and puncture. The success standards of sepsis included fever, the increase of respiration rate,increased heart rate and change in leukocyte count. At 12 hours before operation, and after operation the rats in the Xuebijing group were injected with 4 mL/kg Xuebijing (once every 12 hours for 3 days), and the rats in the others two groups were injected with the same volume of saline, the image analytical system were used to detect the pathological change of intestinal tract mucosa harriers and the expression of macrophage antibody in three groups. All the data were analyzed by rank-sum test and variance analysis(F test). Results Almost all the mucous mem-brahe of small intestine in sham groups were normal. The mucous membrane lesions of small intestine developed in sepsis and Xuebijing groups after 12,24,48,72 hours, and the lesion was severer in sepsis group than that in the Xuebijing group (H=19.732, P<0.01). There were no significant differences on the expression of macrophage antibody in mucous membrane of small intestine between three groups at 3 hours. But at 12, 24, 48 and 72 hours, the expression of macmphage antibody of sepsis and Xnebijing groups increased with time (F=560.13, P< 0.05). Conclusions At the early period of sepsis, intestinal tract mucosa barriers develops varying degrees of damage, and Xnebijing can partly protect intestinal tract mucosa barriers.

Objective To observe the expression change of phosphorylation glogyen synthase kinase 3β at Ser9 [p-GSK3β (Ser9)] and investigate whether GSK3β involved in the retinal ganglion cell (RGC) and optic nerve in rat ocular hypertension model.Methods Thirty health Sprague Dawley (SD) rats with normal intraocular pressure (IOP) were randomly divided into 3 groups(10 cases in each group):control group,2 weeks ocular hypertension(OHT) group and 4 weeks OHT group.The ocular hypertension model was established by using episcleral veins ligation and cauterization.5 eyes from each group were taken for frozen section at week 2 and week 4 after establishing ocular hypertension model.The number of RGC was counted with Nissl's staining.The expression and distribution of p-GSK3β (Ser9) in RGC and optic nerve were detected by immunofluorescence staining.The retinal sample of other 5 rats was harvested for detecting the expression of total glogyen synthase kinase 3 β (total GSK3β) and p-GSK3β (Ser9) by Western blot.Results There was no statistical difference in IOP before modeling among three groups (P =0.89),but there was statistical difference after modeling (P ＜0.01),compared with the control group,the increased rate of IOP in 2 weeks OHT group and 4 weeks OHT group were 59.13％ and 26.93％ (all P ＜ 0.05).The average RGC numbers of 2 weeks OHT group and 4 weeks OHT group were 120 ± 10 per eye and 86 ± 7 per eye,which were both less than the number 149 ± 12 per eye in control rats,there were statistical differences (all P ＜ 0.05).Furthermore,the number of RGC in 4 weeks OHT group was less than 2 weeks OHT group (P ＜0.01).The expression of p-GSK3 β (Ser9) in the retina and optic nerve were positive detected by immunofluorescence,and the intensity of p-GSK3β (Ser9) immunofluorescence staining in RGC and optic nerve of OHT rats were less than model control eyes.The amount of p-GSK3β (Ser9) in retina of 2 weeks OHT rats decreased 19.89％ compared with control group rats (P ＜ 0.05),and the amount of p-GSK3β (Ser9) in retina of 4 weeks OHT rats was significantly decreased 36.46％ compared with control group rats(all P ＜ 0.05).While the total GSK3β did not change(P ＞ 0.05).Conclusion The number of RGC and the expression of p-GSK3β (Ser9) in RGC and optic nerve of OHT rat eyes decreased significantly.The change expression of the p-GSK3β (Ser9) in the RGCs and optic nerve may be correlated with RGC neurodegeneration in glaucomatous disorders.

OBJECTIVETo evaluate the efficacy of internal application of Qigui Mixture (QM) and external application of Qigui Huoxue Lotion (QHL) in treating type 2 diabetic peripheral neuropathy (DNP) patients of qi-yin deficiency complicated phlegm-dampness blocking collaterals syndrome (QYD-PDBCS), and to primarily discuss its mechanism.

METHODSTotally 62 DPN patients of QYD-PDBCS were randomly assigned to the treatment group (31 cases) and the control group (31 cases). All patients received routine comprehensive therapy. Patients in the control group took Mecobalamine Tablet, 500 microg each time, 3 times per day. Patients in the treatment group additionally took QM, 200 mL per day, twice daily. Besides, they had foot bath in QHL 10 - 15 min every evening for 3 months. The efficacy was assessed by Chinese medical symptom integrals and Toronto clinical scoring system (TCSS) before treatment, 2 and 3 months after treatment. The nerve conduction velocity was determined; the serum levels of total antioxidant capacity (T- AOC), malondialdehyde (MDA), and superoxide dismutase (SOD) were detected 2 and 3 months after treatment.

RESULTSThe total effective rates of Chinese medical symptom integrals and TCSS score were obviously higher in the treatment group than in the control group (P < 0.05). The nerve conduction velocity was significantly improved in the treatment group, when compared with before treatment (P < 0.01). There was statistical difference in the nerve conduction velocity difference of right median nerve motor branch, bilateral tibial nerve motor branches, bilateral common peroneal nerve motor branches, bilateral ulnar nerve sensory branches, and left tibial nerve sensory branch (P < 0.05). Compared with before treatment, serum levels of T-AOC and SOD significantly increased, and the level of MDA decreased significantly in the treatment group after 2 and 3 months of treatment (P < 0.01). But only the SOD level increased significantly in the control group (P < 0.01). There was no statistical difference in increased T-AOC level between the two groups after 2 months of treatment (P > 0.05), but there was statistical difference in increased SOD level and decreased MDA level (P < 0.05). There was statistical difference in increased T-AOC and SOD levels and decreased MDA level between the two groups after 3 months of treatment (P < 0.05). No adverse reaction occurred during the therapeutic course.

CONCLUSIONSThe internal application of QM and external application of QHL combined with Mecobalamine in treating DPN was safe and effective, with more significant efficacy than using Mecobalamine alone. Its mechanism might be associated with resistance to oxidative stress.

BACKGROUND: Osteoporosis, known as "a quiet epidemic disease", is an "invisible killer" that impairs the health of the elderly. Fracture as the most dangerous complication of osteoporosis is not only a medical problem, but also a serious social problem. OBJECTIVE: To summarize the selection, establishment methods, characters and evaluation of the animal model of osteoporosis. METHODS: A computed-based search of CBM, WanFang, VIP, CNKI and PubMed databases was conducted for the relevant articles published from January 1986 to December 2016 using the keywords of "osteoporosis, animal models" in English and Chinese, respectively. Finally 39 articles were included for result analysis after reading the title and abstract. RESULTS AND CONCLUSION: Animal experiments play an important role in the studies of osteoporosis, so a desirable animal model should hold similarity, reliability, repeatability, applicability, controllability, efficacy and economy. Osteoporosis is a progressive and long-lasting disease that has different characteristics at different stages. But an animal model only simulates one etiology, one stage, major symptoms and pathophysiological changes, and cannot exhibit the whole pathological changes. The current study suggests that animal species and modeling methods can affect the characters of models, and there is a lack of standards for animal age, feeding methods, modeling time and assessment.

Mesenchymal stem cells (MSCs) represent a population of adult stem cells residing in many tissues, mainly bone marrow, adipose tissue, and umbilical cord. Due to the safety and availability of standard procedures and protocols for isolation, culturing, and characterization of these cells, MSCs have emerged as one of the most promising sources for cell-based cardiac regenerative therapy. Once transplanted into a damaged heart, MSCs release paracrine factors that nurture the injured area, prevent further adverse cardiac remodeling, and mediate tissue repair along with vasculature. Numerous preclinical studies applying MSCs have provided significant benefits following myocardial infarction. Despite promising results from preclinical studies using animal models, MSCs are not up to the mark for human clinical trials. As a result, various approaches have been considered to promote the therapeutic potency of MSCs, such as genetic engineering, physical treatments, growth factor, and pharmacological agents. Each strategy has targeted one or multi-potentials of MSCs. In this review, we will describe diverse approaches that have been developed to promote the therapeutic potential of MSCs for cardiac regenerative therapy. Particularly, we will discuss major characteristics of individual strategy to enhance therapeutic efficacy of MSCs including scientific principles, advantages, limitations, and improving factors. This article also will briefly introduce recent novel approaches that MSCs enhanced therapeutic potentials of other cells for cardiac repair.
