Objective To observe the effects of Qutantongluo decoction on the expression of TGF-β1 in renal tissue of diabetic nephropathy(DN) rats,which can help to understand the mechanism of action.Methods The rats models of diabetic nephropathy were established by injecting with streptozotocin intraperi-toneally.All Wistar rats were randomly divided into 6 groups:the normal control group,the model control group,Benazepril Hydrochloridec group ( 1 mg/kg ·d-1 ),Qutantongluo decoction low dose group (3 g/kg ·d-1 ),Qutantongluo decoction median dose group (4.5 g/kg · d-1 ),and Qutantongluo decoction high dose group (6 g/kg · d-1 ).Rats in the normal control group and the model control group were given celiac perfusion of distilled water once at the same time and dose.All the rats were gavaged once daily for 8 weeks.The expression of TGF-β1 at the level of gene and protein in renal tissue were tested by immunohistochemistry and RT-PCR methods.Results Compared with the model control group(2.79±0.22),the expression of TGF-β1 at the level of protein in renal tissue of Benazepril Hydrochloridec group (1.55 ±0.12)and the Qutantongluo decoction low dose group ( 1.54± 0.16),Qutantongluo decoction median dose group (1.49 ± 0.17),Qutantongluo decoction high dose group(l.39±0.25) decreased significantly (P＜0.05).Compared with the model control group (0.35±0.07),the expression of TGF-β1 mRNA in renal tissue of Benazepril Hydrochloridec group(0.35± 0.07)and the Qutantongluo decoction low dose group(0.39±0.03),Qutantongluo decoction median dose group (0.35± 0.06),Qutantongluo decoction high dose group (0.32± 0.07) decreased significantly (P＜0.05).Conclusion Qutantongluo decoction can down regulate the expression of TGF-β1 in kidney,which may be one of the mechanisms of Qutantongluo decoction effectiveness in clinical treatment of diabetic nephropathies.

Objective Discuss the studies of infant nutrition problems of 6 to 24 months old infants in poverty areas and make reasonable suggestions.Methods Collect research reports about child malnutrition at home and abroad,and analyze the monitoring data of nutrition improvement program for children in poor areas carried out by Natiend Institate for Nutrition and Health for of Chinese Center for Disease Control and Prevention.Discuss the nutritional status and related risks of infants aged 6-24 months in poor areas.Results The nutritional problems of rural children in poor areas were prominent.The growth retardation rate of infants aged 6-24 months was 7.6％.Anemia,overweight and obesity are becoming increasingly prominent.Conclusion The nutrition status of 6-24 month old infants in poor areas in China should be paid attention.

Objective To establish the in vitro biofilm model of Laribacter hongkongensis(LH),to analyze the type Ⅰ integron related genes carried by LH and to investigate the mechanism of LH resistance to quinolones.Methods The biofilm forming abilities of LH clinical isolates were determined by Giemsa staining qualitative method and by crystal violet staining semi-quantitative method.The sensitivity of LH to norfloxacin,ofloxacin,levofloxacin,ciprofloxacin and lomefloxacin in both planktonic and biofilm conditions were dectermined by broth microdilution susceptibility tests.Type I integron related genes carried in 18 LH strains resistant to quinolone were detected by PCR amplification method.Results The detection results by Giemsa staining demonstrated that 36 strains in 55 LH clinical isolates formed visible biofilm,and the biofilm formation rate was 65.4%(36/55).In the biofilm forming ability detected by crystal violet staining semi-quantitative method,OD560≤0.15 was in 8 strains of LH,0.150.20 in 7 strains respectively.The levels of minimal biofilm inhibitory concentration in norfloxacin,ofloxacin,levofloxacin,ciprofloxacin and lomefloxacin to LH were respectively higher than the minimal inhibitory concentration(MIC) in the corresponding floating bacteria(P<0.05).Among 55 strains of LH,18 strains were resistant to quinolones,the resistance rate was 32.7%,and the type I integron in 18 strains of LH carried the drug resistant genes,these drug resistant genes played the drug resistance role in corresponding bacterial strains.Conclusion Drug resistance gene formation and widespread of LH may be associated with type I integron.

Objective To explore the immunomodulatory effects of seaweed polysaccharide(PSS)in aged mice induced by D-ga-lactose (D-gal).Methods D-gal was injected intraperitoneally to establish the aged mice model,meanwhile the aged mice was intra-gastricly administrated by PSS.Peritoneal macrophages were collected,and macrophage secretion of nitric oxide (NO),nitric oxide synthase (NOS)levels and expression levels of inducible nitric oxide synthase (iNOS)mRNA were detected.The spleen indexs of the agd mice were calculated,and effects of PSS on spleen microscopic structure of mouse were observed.The changes of spleen cell cycle in aged model mice were detected by flow cytometry assay.Results PSS could enhance macrophage synthesis of NO and NOS of the aged mice and up-regulate the expression of iNOS mRNA levels.And the spleen index of the aged mice increased obviously, the hyperplasia of spleen capsule was obvious.Moreover,PSS could increase the percentage of S phase and G2/M phase cells of the aged mice spleen.Conclusion PSS could enhance the immune function of aged mice induced by D-gal,which is worthy of further study,which development.

The effects of amino acid electuary on experimental liver fibrosis in rats with chronic liver injury induced by CCI4 were studied. The results showed that the electuary could prevent the decrease in body weight and food intake, reduce the levels of serum glutamic-pyruvic transaminase activities, elevate contents of total serum protein and serum albumin, normalize the serum ratio of BCAA to AAA and disordered amino acid pattern and suppress degeneration, necrosis and fibrosis of liver tissues in rats with chromc liver injury. These results indicate that the amino acid electuary has beneficial effects in prevention and treatment of liver fibrosis.

Objective To develop a special ambulance for airfield rescue of pilots in danger or offering medical care for pilots in flight.Of course the ambulance can also be used to rescue the wounded daily or in the war.Methods The ambulance owned a cross-country motorcar chassis and bearing carriage.A luffing extension-jib was installed on top of the carriage with a telescopic nacelle.The medical carriage owned a generator,air-conditioner,launder & antisepsis facilities,telescopic medical table,Air Force medical facilities for first aid and so on.It could simultaneously treat 2 injured pilots in lying position.Oxygen outputs were equipped to sustain Persons in carriage.Result The maximal speed of the ambulance was 95 km/h.The time of simulated rescue was about 3 minutes in the maxium height.Conclusion Without new staff established,the ambulance can adapt to any road and is suitable to war field.It can arrive at the location of flight accident quickly and rescue the pilot rapidly.It meets the needs of medical support in flight,war-time medical care in airport and mobile accompanying support.

Surgery remains the cornerstone of treatment for esophageal cancer, although improvements have been made in surgical maneuvers and perioperative care, serious complications still occur after operation. The reconstruction of alimentary tract is a key procedure to ensure success of operation, it is related to perioperative complication and prognosis. Selection of procedure should be individualized based on the stage and location of the disease, medical condition and the surgeon's experience.

Malnutrition is common in patients with inflammatory bowel disease(IBD). The therapeutic role of nutrition has attracted more and more attention in the development of IBD. In recent years, researches have demonstrated that nutrition support has its unique advantages in improving patients nutritional status and reducing adverse events, and it has been recommended as the first line therapy in children with active Crohn disease. Since there are no standardized guidelines of nutritional support therapy worldwide, this article is to review the relationship between nutrition and IBD, the choice of nutritional therapy mode, the duration of the nutritional treatment and evaluation of therapeutic effects based on Expert Consensus on Nutrition Support Therapy of Inflammatory Bowel Disease (2013·Shenzhen).
