Chronic kidney disease (CKD) is a serious chronic disease with high incidence, poor prognosis, and a variety of complications. Indoxyl-sulfate (IS) and p-cresol sulfate (PCS) are two typical gut-derived uremic toxins, which are produced by the co-metabolism of intestinal microbes and the host. With the progression of CKD, gut-derived uremic toxins such as IS and PCS accumulate in patients with CKD and thereafter accelerate the progression of CKD. Gut microbiota is closely related with CKD, and targeting gut microbiota to regulate gut-derived uremic toxins synthesis and metabolic pathways may be a promising strategy to delay the progression of CKD. In this paper, the relationship between gut microbiota, gut-derived uremic toxins, and CKD was analyzed, and the strategy to delay the progression of CKD by targeting gut microbiota and uremic toxins metabolism pathway was proposed.

The isolate XGH2321,which isolated from the rhizospheric soil of Rhizophora stylosa Griff in Dongzhaigang Mangrove Nature Reserve in China,was identified as a fungus in the genera of Penicillium based on its morphological characteristics and internal transcribed spacer(ITS) sequence analysis.After in-oculated in the modified CzapeK-DoX medium(consisted of 4% corn steep,0.3% NaNO3,0.05% KCl,0.1% K2HPO4,0.05% MgSO4,pH 7.4,9% salinity),and cultured under the condition of 28?C in a rotary shaker at 160 r/min for 7 days,the extracts of ethyl acetate and water-soluble from the fermentation broth showed the apparent antibacterial activities against the growth of Staphylococcus aureus,Sarcina lutea,and Bacillus subtilis with the minimum inhibitory concentration(MIC) of 800 ?g/mL and 400 ?g/mL,respectively.While at the same time,these two extracts could also suppress the growth of the plant pathogen,Rhizoctonia solani with MIC of 400 ?g/mL and 200 ?g/mL,respectively.

Objective To observe the changes of respiratory and hemodynamic functions in children with different age undergoing laparoscopic Nissen's fundoplication(LNF). Methods Thirty-three children with LNF were divided into three groups according to the age: group Ⅰ,1 to 12 months,n=13;group Ⅱ,1 to 3 years old,n=10;and group Ⅲ,4 to 7 years,n=10.Heart rate(HR),mean arterial pressure,Ppeak,compliance of the respiratory system(CRS) and end-tidal carbon dioxide pressure(PETCO2) were recorded 5 min before pneumoperitoneum(T0),10 min(T1),60 min(T2) after pneumoperitoneum and 10 min after deflation(T3),and parameters of blood gas analysis such as PaCO2 were measured at the same time. Results Compared with those at T0,HR,Ppeak,PETCO2 and the difference between PaCO2 and PETCO2(Pa-ETCO2)were significantly increased at T1 and T2,while CRS was significantly decreased.The most significant changes were found in group Ⅰ. Conclusion The changes of respiratory and hemodynamic functions are observed in children undergoing LNF,and anesthesia management should be enhanced for those within 1 to 12 months old who experience the most significant changes.

Objective To investigate the clinical efficacy and mechanism of vacuum-assisted closure (VAC) in the preoperative and postoperative treatment of bedsore united with skin flap.Methods Twenty two cases with bedsore were randomly divided into experimental and control groups.In the control group,the surgery of flap was performed after the treatment of continuous negative pressure about 7-10 days and the VAC was not applied after operation.While in the experimental group,VAC was not used before operation.It was applied on flaps as soon as sutured the border of flap and decubitus ulcers and removed after 7-10 days.By comparing the general appearance of two groups,microvessel count and the detection rate of bacterial culture and other indicators,the clinical effects of two treatments were investigated and the preliminary mechanism was analyzed.Results After preoperative VAC treatment,11 cases of control group showed a little granulation tissue growth,less subcutaneous hematoma and wound effusion,increased microvessel count and negative bacterial culture.However,there were 4 cases of death cavity residual,subcutaneous hematoma and wound effusion,positive bacterial culture and another 4 cases of delayed healing with skin flap repairing bedsore.The application of VAC in experimental group showed close contact of flap with the basement,less effusion,increased microvessel count and negative bacterial culture.One case of skin flap had a small area of separation,after the dressing of skin and the flap survived.The other wounds healed by first intention.Conclusions The use of VAC to repair bedsore can reduce the number of operation,and it is beneficial to the flap survival.

OBJECTIVETo investigate the induction and culture of adventitious root of Panax notoginseng.

METHODThree ways, induction from the explants of three-year-old P. notoginseng. The explants of regenerated shoots and calluses, were used to induce adventitious roots. The effects of 2, 4-dichlorophenoxyacetic acid, indole-3-butyric acid and naphthylacetic acid on adventitious root induction were investigated respectively. The effects of four modes of separating adventitious roots from the parent tissues on culture in vitro were compared.

RESULTAdventitious roots were successfully induced by three methods, of which the young flower bud callus was the best material for the induction of adventitious root. Indole-3-butyric acid possessed the strongest potency for induction. The liquid culture system was established by continuous culture of adventitious roots together with their parent tissues before separated.

CONCLUSIONThe acquisition and culture in vitro in liquid culture system of adventitious roots of P. notoginseng lay a foundation for the next investigation.

ObjectiveBy analyzing the epidemiological characteristics and trends of brucellosis in Hebei province,provide a scientific basis for the formulation of strategies for effective prevention and control of the disease.MethodsUsing the descriptive epidemiological method,data of the “China information system for disease control and prevention” from 2006 to 2010 were statistically analyzed.ResultsThere were 13 632 reported cases from 2006 to 2010 in Hebei province,no death,the annual incidence rates reported were 3.4068/10 million,3.4851/10 million,4.5701/10 million,4.6045/10 million,and 3.5582/10 million,respectively.Eleven counties throughout the province had reported cases.The cases were found intensively in Zhangjiakou,Chengde,Baoding,Handan and Shijiazhuang,which accounting for 90.02％ (12 271/13 632) of the total cases.The disease was found each month throughout the year,and showed a seasonal cycle with peak period in spring and summer.The disease was most commonly found in 25 - 65 age people,which accounting for 84.57％(11 529/13 632).The incidence in male was higher than that of female,and male to female ratio was about 3.56:1.00.Vocational high risk population was farmers,accounting for 91.15％ of the total cases(12 425/13 632).ConclusionsBrucellosis epidemic in Hebei province is relatively serious,and the epidemic range has expand each year,even highly active in some particular areas.To control the outbreak of brucellosis,departments cooperation between health and animal husbandry should be strengthened; management of source of infection should be strengthened; health education and behavior intervention should be carried out thoroughly and deeply for high-risk groups.

Objective To explore the clinical features and treatment of skin ulcers.Methods A total of 185 skin ulcer patients with clinical data was analyzed retrospectively in our hospital from October 2014-October 2016.Results Of the 185 patients with skin ulcers,84(45.4％) were 51-70 years old,diabetic ulcers were most common,and most occurred in ankle (44.3％) and limbs (35.7％).After further statistical analysis,the healing rate of patients treated by surgery was significantly higher than non-surgical patients.Surgical procedures of local flap transfer after ulcer resection were most commonly used and of the highest healing rate.The number of ulcers,the largest diameter of ulcers,scar ulcers and blood barrier ulcers were four factors that were independent of the outcome of skin ulcers.Conclusions Skin ulcers hospitalized patients are more common in patients over 50 years of age,occur most in the lower limbs.Surgical therapy is the preferred treatment for most ulcers,of which local flap transfer after ulcer resection has the best effect.Ulcer patients should actively treat the primary disease,strengthen the care,early diagnosis,and early treatment.

OBJECTIVETo study the effect of ursolic acid (UA), apentacyclic triterpene acid, on MCF-7 cell apoptosis, and probable mechanism involved by detecting the expressions of caspase-3 and poly ADP-ribose polymerase(PARP) at protein level.

METHODMCF-7 cells were cultured with different concentrations of UA. Growth inhibition of UA on MCF-7 cells was evaluated by MTT assay. Cell cycle and sub-G1 peak were performed by FCM. Morphologic changes of UA-treated cells were observed by light microscope. Apoptotic cells with condensed or fragmented nuclei were visualized by Ho 33258 staining by a fluorescence microscope (EX: U. V.). The protein expression of caspase-3 and PARP was analyzed by immunofluorescence cell staining (SABC-Cy3).

RESULT24 hours after UA treatment, inhibition of MCF-7 cell growth was concentration-dependent. The IC50 value for UA was (22.6 +/- 3.0) micromo x L(-1). Cell cycle anaysis by FCM showed that 50 micromol x L(-1) of UA arrested MCF-7 cell cycle at G0 - G1 phase. Morphological changes of MCF-7 Cells exhibited many of the hallmark features of apoptosis, including chromatin clumps and aggregation and DNA fragmentation. UA increased caspase-3 protein expression.

CONCLUSIONThe results suggest that UA evokes MCF-7 cell apoptosis is correlation with the up-regulation of caspase-3. Our study indicated that UA might be a potential Chinese medical component for breast neoplasm.
