Toll-like receptor 4 (TLR4), the natural receptor of lipopolysaccharide(LPS), plays an important role in the regulation of acute inflammation, intracellular signal transduction and cell apoptosis. TLR4 over expresses in both acute inflammation and fibrotic tissues, which suggests that TLR4 may be essential in acute inflammation and subsequent fibrosis. Nowadays, some progress has been made in the exploration of TLR4 in pathogenesis and treatment of liver cirrhosis and pulmonary fibrosis. TLR4 may become a new target in the treatment of human fibrotic diseases including liver cirrhosis and pulmonary fibrosis. The research status of TLR4 in human fibrotic diseases and its future development are reviewed in this paper.

Clinical data of 448 patients aged ≥60 years with osteoporotic hip fractures admitted in Shanghai Huashan Hospital between January 2010 and December 2014 were retrospectively analyzed.Among 448 cases,there were 143 males and 305 females;196 cases aged 80-89 years (43.8％) and 137 cases aged 70-79 years (30.6％);304 cases of femoral neck fracture (67.9％) and 144 cases of intertrochanteric femoral fracture (32.1％);the fractures caused by fall in 328 cases (73.2％) and comorbidity with hypertension and diabetes mellitus in 415 cases (92.6％).Two hundred and sixty eight patients were followed up for 2 years,among whom re-fractures occurred in 17 cases.The study indicates that health education is important for prevention of osteoporotic fractures in elderly people.

Objective To establish a sensitive, rapid and simple high-performance liquid chromatography (HPLC) method for the determination of amphotericin B (AraB) and itraconazole (ITZ) in human cerebrospinal fluid (CSF). Methods Solid-phase extraction (SPE) was involved in sample preparation in this method, followed by reverse-phase separation under two different chromatographic systems. Results The tinearity for both AraB and ITZ ranged from 5 ng/mL to 100 ng/mL and the inter-day and intra-day RSD were both below 7.6% at the concentrations of 20,50 and 100 ng/mL. Conclusions The method we established has been applied to the therapeutic drug monitoring on cryptococcal-meningitis-infected patients who were given comedication of these two drugs.

A strain,Actinobacillus succinogenes CGMCC 1593,producing succinic acid was isolated from bovin rumen,which could pro- duces succinic acid by anaerobic fermentation.A series of morphological and biochemical characteristics and sequence analysis of 16S rDNA reveal that it belongs to Actinobacillus succinogenes.When cultured anaerobically in medium containing 60 g/L glucose as carbon source,the strain produces 25.8 g/L of succnic acid.

Objective: To observe the therapeutic action of earth enteral nutrition after jejunum interposition in patients with carcinoma of gastric cardia.Methods: Sixty-two patients after jejunum interposition were divided into early enteral nutrition group(n=33) and parenteral alimentation group(n=29).The clinical observation index and nutrition index were compared between the two groups.Results: The enteral nutrition group had more advantages than the parenteral alimentation group in the aspects of clinical observation index postoperative complication and nutrition index.Conclusion: Early enteral nutrition could improve gastrointestinal function and nutritional state and decrease the incidence rate of postoperative complication.

Objective To observe the effects of the re-therapeutic on later stage of sudden deafness.Methods Patients who met the criteria for sudden deafness and showed poor response tO conventional therapy over two months were recruited and assigned randomly for re-therapy.The pure tone audiometry was conducted before and after re-treatment in 103 patients(112 ears).Sodium bicarbonate and dexamethasone were iniected by intravenous drip for two days and batroxobin 5 BU for 6 days.Statistics were made in the effecency of the re-treatment.Results The effective rate of re-treatment group was 46.43% and the difference was significant before and after retreatment(P<0.01).Conclusion Combined use of sodium bicarbonate dexamethasone and batroxobin is effective in re-treating later sudden deafness.

Objective:To study of immuno-intervention with prostaglandin E2(PGE_2) on tumor necrsis factor(TNF-?),interleukin 10(IL-10),SOD and NO in rats attacked by vibrio vulnificus.Methods:27 normal rats and 27 hepatopathy rats,they were divided into Vv attacked group,ofloxacin treatment group and combined PGE_2 with ofloxacin protect group(n=9).Results:The result of cytokines detection showed that serum IL-10 and SOD level of combined PGE_2 with ofloxacin protect group was significantly higher than that of ofloxacin treatment group,however,TNF-? and NO level of PGE_2 immuno-protect group were significantly lower than those of ofloxacin treatment group(P

AIM: To investigate the expression and functional role of p38MAPK in the kidney after unilateral ureteral obstruction in rats. METHODS: Unilateral ureteral obstruction (UUO) models were induced by ligating the left ureter. Rats were sacrificed at 1 h, 3 h, 6 h, 12 h, 1, 3, 5, 7, 14, 21, and 28 days after UUO was initiated. p38MAPK activity was assayed by immunohistochemical staining and specific substrate phosphorylation with immunoprecipitation and Western blotting. TGF? mRNA and protein expression were analyzed with in situ hybridization and immunohistochemical stainning. RESULTS: A basic p38MAPK activity was detectable in the normal kidney(0.22?0.06). p38MAPK pathway was rapidly activated at 1 hour(0.45?0.14 vs control, P

Objective We studied the clinical features and its significance of coal worker's pneumoconiosis combined with sleep apnea Methods In 40 patients with coal worker's pneumoconiosis combined with sleep apnea hospitalized from February 2006 to December 2009, polysomnography ( PSG) , blood routine, urine routine, blood pressure and biochemical indicators were measured and analyzed. Results Patients with coal worker' s pneumoconiosis combined with sleep apnea manifested mainly as duplicate hypoxemia and multi-organ dysfunction: high blood pressure, dysfunction of heart, lung and kidney, increase of serum glucose, blood lipids, blood uric acid and finally led a vicious cycle to aggravate the above mentioned damage. Conclusions In clinical, multiple-organ dysfunction resulted from severe hypoxemia and hypercapnia caused by coal worker's pneumoconiosis combined with sleep apnea, should be fully aware and give ational and effective treatment early to reverse or delay the further function damages of multiple organs, and therefore significantly improve the prognosis.
