Objective To explore the efficacy and safety of transjugular intrahepatic portosystemic shunt (TIPS) in the treatment of hepatorenal syndrome (HRS).Methods From January 2009 to December 2012,the clinical data of three type 1 HRS cases and five type 2 HRS cases received TIPS operation were collected.The volume of 24 h urine,liver and renal function,and the occurrence of complications of portal hypertension were recorded and followed-up.Wilcoxon rank sum test was performed for non-normal distributed measurement data.Results TIPS of all the patients was successful and combined with devascularization in four patients.Before operation,the serum creatinine and volume of urine was 204.0 (180.8,229.8) μmol/L and 810 (600,925) mL,seven days after operation was 160.7 (120.2,184.0) μmol/L and 1 300 (975,1 500) mL,respectively,and the differences were statistically significant (Z=-2.1 and-2.2,both P＜0.05).One month after operation,renal function of five patients recovered to normal.At the 7th day after operation,total bilirubin level of three patients increased and that of two patients decreased to the preoperative base line value at one month and three month.Mild or moderate hepatic encephalopathy occurred in three patients after operation and relieved after medicine treatment.At 6th month after operation,two of three type 1 HRS patients survived.Of five type 2 HRS patients,one received liver transplantation at 6th week after operation,three of the left four cases survived at the 6th month after operation.Conclusion After safety and efficacy were evaluated,TIPS may be one of the methods used for the treatment of HRS.

Mind map is an effective and intuitive knowledge organization and presentation tool which can help computer teaching commendably. We can use Mind Map to design and organize the whole teaching process, including preparing, designing, guiding, analyzing and reviewing. This way can turns tedious logic of computer teaching into imagery thinking and helps medical students improv-ing their learning effect of computer courses.

Objective To explore the expression of G protein inwardly rectifier potassium channels subunit 2(GIRK*!2) in hippocampus of temporal epileptic rat.Methods After temporal lobe epilepsy was induced by kainic acid (KA), we took advantage of in situ hybridization to investigate the altered expression of GIRK*!2 mRNA in rat hippocampus.Results GIRK*!2 mRNA significantly increased in epileptic rats dentate gyrus region compared with normal control( P

Objective To explore the preliminary construction of nursing care quality index based on the characteristics of ophthalmic nursing. Methods Through literature review and experts′discussion, the preliminary construction of nursing care quality index were designed. The Delphi method was used to revise the indicators. Results After two rounds of Delphi procedure, the opinion of the experts became consistent. Questionnaire collecting rates of the two rounds were both 100％, and cooperation index were 0.236 and 0.292 respectively (P<0.01), two first level quality indicators were confirmed, namely ophthalmic care operations (five second level indicators) and health education (four second level indicators). Conclusion The ophthalmic nursing care quality indicators were scientific, reliable and feasible, which could provide objective and quantified basis for the management of nursing care quality.

Objective To study the effect of intracerebroventricular(icv) injectionon acetylcholine(ACh) on the elecric activities of pain-related neurons in the hippocampal CA1 area of rat.Methods Trains of the electric impulses applied to the right sciatic nerve were used as noxious stimuli.The discharges of neurons were led out by extracellular recording method with glass microelectrodes.Results Icv injection of ACh(20?g/10?l) caused an decrease of the evoked discharge frequency of pain-excited neurons(PEN) and a prolongation latency as well as an increase of the evoked discharge of pain-inhibited neurons(PIN) and a shortening of inhibitory duration.Conclusion The response of pain-related neurons in hippocampal CA1 area to the noxious stimulation is weakened by icv injection of ACh,exhibiting analgesic effect.

Congenital heart disease with left-to-right shunt easily lead to pulmonary hypertension.Currently agreed about its mechanism:shear stress induced by high pulmonary blood flow stimulus pulmonary endothelium,to start regulation of genetic transcription,to initiate a series of molecular biology and pathophysiology changes,and finally to lead to pulmonary vascular pathologic remolding.Nuclear factor(NF)-?B is a kind of nuclear factor with multiple biological effect and play an important role in pulmonary vascular remolding.NF-?B signal can be actiacted by high blood flow.Its target gene products,for example,vasoactive mediators,cytokines,make pulmonary vessels difficulty to maintain the normal structure and cause pulmonary vascular contraction and remolding,thus,pulmonary arterial pressure increases.

Objective To investigate the hypothesis that food allergy in infants may be associated with variation in their intestinal microflora. The formation of intestinal microflora in healthy infants and changes in food allergic infants were detected.Methods 16S rRNA gene sequences specific for bifidobacterium, lactobacillus and escherichia coli in fecal were quantitatively detected by real-time PCR. The three fecal floras were assessed in 71 healthy infants and 100 infants with food allergy. Results After birth,there were bifidobacteria colonized in infantile intestine,then the number increased rapidly up to 5 times at the sixth month, which was always the preponderant flora. Lactobacilli was also presented in infantile intestine 1 month after birth and augment gradually. The number of Escherichia coli was less than bifidobacteria and lactobacilli and appeared to decline during the early infants. The number of bifidobacteria and lactobacilli in the infants with food allergy were markedly less than that in the healthy infants, but escherichia coli was significantly more than that in the healthy infants.Conclusions During the first year of life,the intestinal microflora in infants is in a developing process. Compared with the healthy infants,bifidobacteria and lactobacilli decrease, but escherichia coli increase in the food allergic infants.These results indicate that the probiotics may be benefit to the prevention and treatment of food allergy.

Objective:To explore the antibacterial effect of Belamcanda Chinensis DC and Por tulaca oleracece L on P.aeruginosa (PA) in vitro.Methods:Fourty six strains PA were tested for minimum inhibition concentrati on ( MIC) by water decoct agents of the two drugs.MIC50 and MIC90 were st atistically studied.Results:For Belamcanda Chinensis DC,MIC was 31.25～3.90 g/L;MIC50 was 7 .81 g/L,and MIC90 was 15.62 g/L;whereas， for portulaca oleracece L,MIC was 31 .25～7.81 g/L, MIC50 was 15.62 g/L,and MIC90 was 31.25 g/L.Conclusion:Both of the two drugs have stronger antibacterial effects on P.ae ruginsosa in vitro.
