Objective To summarize the effect and experience of nursing of patients with rheumatic valvular heart disease with atrial fibrillation treated with Cox Ⅲ labyrinth and simultaneous valve replace-ment operation. Methods A retrospective analysis was carried out in the nursing of 58 patients with rheumatic valvular heart disease with atrial fibrillation treated with Cox Ⅲ labyrinth and simultaneous valve replacement operation in our hospital from April 2006 to July 2008. Results One patient died of periop-erative renal failure,one died of low cardiac output,one died of infectious endoearditis.Tbe mortality rate reached 5.2%.Other patients were discharged from hospital after completely cured.The survived patients maintained sinus rate during hospitalization days after operation and short-term follow-up after being dis-charged.Among 43 patients who completed follow-up of 6 months after operation,3 patients (7.0%) damon-strated atrial fibrillation,while others still kept sinus rate. Conclusions Attention should be paid to psy-chological nursing,respiratory tract preparation,cardiac function monitoring and nursing of anticoagulation treatment for patients treated with Cox Ⅲ labyrinth and simultaneous valve replacement operation.

Objective To evaluate the therapeutic effect and safety of inhaling magnesium sulfate on infants with acute bronc-hiolitis. Methods Ninty infants with bronchiolitis were divided into 3 groups randomly and received either magnesium sulfate infusion inhalation or intravenous injection or normal saline inhalation respectively. The change of parameters of each group were observed and compared. Results Magnesium sulfate inhalation group and intravenous injection group were superior to control group in terms of the improvement of blood gas, clinical scores, continuous time of symptoms,signs, hospital days and clinical total efficiency(P

Objective To explore the conditions, safety and efifcacy of exchange transfusion for extremely severe hyper-bilirubinemia in term newborns requiring mechanical ventilation. Methods Ten full-term newborns of extremely severe hyper-bilirubinemia requiring mechanical ventilation were selected from January 2010 to March 2013 in the department of neonatology. After stable vital sign was achieved by the use of conventional life support, peripheral arterial and venous synchronous exchange transfusion was performed. The bilirubin, platelets, blood calcium, blood coagulation and blood gas were monitored before and after exchange transfusion. The effects and adverse events of exchange transfusion in newborns on mechanical ventilation were observed. Results There was no death in the study, and the replacement rate of total bilirubin was 50.5%. The main adverse event was thrombocytopenia (80%). There was a signiifcant difference in platelet counting before and after exchange transfusion (P<0.05). There was no signiifcant difference in blood coagulation, pH/HCO3-of the blood gas, prothrombin time (PT) and acti-vated partial thromboplastin time (APTT) before and after exchange transfusion. Conclusions It is relatively safe to implement an exchange transfusion in the full-term newborns with severe hyperbilirubinemia in newborns requiring mechanical ventilation, but the use of conventional life support is prerequisite because it stabilizes vital signs. The relatively ideal replacement rate of bili-rubin and the low incidence of adverse reactions are expected. However long-term prognosis of neural system is still unknown.

Background:The incidence of ulcerative colitis (UC)in developed countries is higher than that in developing countries,which may be related with westernized lifestyle,especially high animal protein and low complex carbohydrate diet. With the increased high fat and meat intake,synthesis and secretion of bile acid in liver is also increased,which may have an impact on the occurrence of UC. Aims:To investigate the expressions of farnesoid X receptor (FXR)and G protein-coupled bile acid receptor 5 (TGR5)in patients with UC. Methods:Thirty patients with active UC from January 2013 to June 2016 at the Affiliated Jiangning Hospital of Nanjing Medical University were enrolled,and 30 healthy subjects were served as controls. Expressions of FXR and TGR5 were determined by immunohistochemistry. Results:Compared with control group,expression of FXR was significantly decreased in UC patients (4. 63 ± 2. 07 vs. 6. 91 ± 2. 62,P =0. 00),however,no significant difference in expression of TGR5 was found between the two groups (6. 70 ± 2. 90 vs. 6. 11 ± 2. 44,P = 0. 40). Expression of FXR was significantly increased in right hemicolon colitis than in left hemicolon colitis (P < 0. 05). Conclusions:There is a significant decrease in FXR in active UC patients,indicating that FXR may have some role in the pathogenesis of UC,however,TGR5 may have no obvious effect in the pathogenesis of UC.

Objective To study the morphologic and pathological characteristics of cat scratch disease(CSD).Methods Eight cases with clinical data and tissue blocks were collected in Guangxi Zhuang Autonomous Region and Hainan Province.The tissues were successively stained by hematox- ylin and eosin,Warthin-Starry(W-S),acid fast and periodic acid-schiff(PAS)methods to study the histopathological changes and pathogens.Results W-S positive Bartonella henselae was the major pathogen of CSD and there was no acid-fast or PAS positive pathogen could be found in the tissues. There were three forms of histological representation as follows:plasmocytoid monocytes(PMO)and monocytoid B-cells(MBC)hyperplasia plus neutrophils immersion in lymphatic sinus(2 cases); MBC rich granuloma and micro-abscess formation(3 cases); starlit abscess with little or no bacteria in the granuloma(3 cases).Conclusions Bartonella henselae mainly transmits through cats.Contact histo- ry with cats and lymphadenectasis suggest the possibility of CSD.The diagnosis can be confirmed by the presence of W-S staining positive bacteria,MBC rich granuloma or micro-abscess and neutrophil reactions in histopathological exam.

Objective To explore the effect of Fas/FasL pathway on fluoride.induced apoptosis in hurnan neumbla8toma SH-SY5Y cells.Methods The cell survival rate,percentage of apoptosis,and mRNA expression levels of Fas and FasL were measured respectively after the SH-SY5Y cells were exposed to O(control),20,40,80 mg/L sodium nuoride(NaF)for 24 hours/n vitro.Furthermore,the changes of the percentage of apoptosis and mRNA expression levels of Fas and FasL in 40 mg/L NaF-treated groups incubated with activaling or neutralizing anti-Fas antibody(CH11 or ZB4)also observed respectively.Results Compared with the control group(100.00%), the cell surval rates in 40,80 mg/L NaF-treated groups[(84.63±2.57)%,(69.04±5.63)%]were significandy lower(P<0.01).The percentage of apoptosis in 40,80 mg/L NaF.treated groups[(8.54±1.95)%.(17.94±2.71)%]were higher(P<0.05)than thal in the control group[(3.32±1.33)%],and increased with the dose of NaF.NaF could up-regulate Fas and FasL mRNA expression,and increased the Fas/β-actin [40 ms/L group (0.94±0.51),80 mg/L group(0.99±0.12)]and FasL/β-actin[40 mg/L group(0.96±0.42),80 mg/L group(0.99±0.24)] ratio,compared with the control[Eas/β-actin(0.50±0.33),FasL/β-actin(0.58±0.23)],both the difference had 8tatistical significances (P<0.05).NaF and CH I 1 had a synergisfic effect on apoptosis and mRNA expression levels of Fas and FasLL(F=32.89,18.46,.14.69,P<0.01)while NaF and ZB4 had an antagonistic effect (F=5.73,24.26,10.17,P<0.05 or<0.01).Conclusion NaF exposure can cause apoptosis in SH-Y5Y cells,and the Fas/FasL pmhway may play an important role in NaF-induced apoptosis.

The aim of the paper is to observe the distribution of the endophytic fungi in leaves of Aquilaria sinensis by using permanent paraffin-cut section, optical microscope photography and histochemistry. Total DNA was extracted with modified CTAB method and rDNA ITS regions of plant and endophytic fungi were amplified with eukaryotic universal primers. The rDNA ITS amplicon was characterized by RFLP analysis, sequencing of rDNA ITS library and phylogenetic analyses using PAUP by maximum parsimony. Fusarium sp. A2 was used to induce the formation of resinous in A. sinensis trees. As a result, endophytic fungi mainly distributed in spongy and phloem in leaf. Endophytic fungi distributed in the phloem in agarwood-producing tree and had a relatively high abundance. Phoma sp. and Collectrotrichum sp. were the absolute advantage species in the leaf tissues of non-resinous and agarwood-producing tree, respectively. Collectrotrichum sp. was the only fungal species detected both in the two types of A. sinensis with different levels of abundance. The culture-independent molecular method can be used to identify fungal species directly and rapidly from the plant tissues. Endophytic fungal communities in non-resinous and agarwood-producing A. sinensis leaf tissues were quite different.
