BACKGROUND:Heart valve surgery combined with coronary artery bypass grafting has been gradual y used for treatment of coronary heart disease combined with cardiac valve disease.
OBJECTIVE:To retrospectively summarize the experience of combined coronary artery bypass grafting and valvular procedure.
METHODS:Total y 51 patients who underwent combined heart valve surgery and coronary artery bypass grafting were retrospectively analyzed, including 10 cases with aortic valve replacement, 14 cases with mitral valve replacement, eight cases with mitral valve replacement combined with tricuspid annuloplasty, four cases with aortic valve and mitral valve replacement, three cases with aortic valve and mitral valve replacement combined with tricuspid annuloplasty, seven cases with mitral valvuloplasty, and five cases with mitral valvuloplasty combined with tricuspid annuloplasty.
RESULTS AND CONCLUSION:Biovalve replacement was performed in nine patients, mechanical valves replacement in 31 cases, mitral valvuloplasty in 11 cases and tricuspid annuloplasty in 16 cases. There were total y 109 bypass graft vessels, and the average number of coronary artery bypass grafts was (1.92±0.73) branches. Four cases died within 30 days postoperatively, and 47 patients were successful y discharged from the hospital. Forty-five of 47 discharging patients were fol owed for 3-48 months. One case died of cerebral infarction within 6 months postoperatively, and another case died of cardiac dysfunction over 1 year after operation. The heart function of 45 survival patients was significantly improved. The comprehensive analysis showed that improving the heart function preoperatively, strengthening myocardial protection, shortening operation and myocardial ischemia time, and complete revascularization are the key factors for successful operation.

Objective:To explore the effect of feeding via the transpyloric route on the gastrointestinal function in very low birth weight (VLBW) infants and find the best early enteral nutrition protocol.Methods:Sixty VLBW infants were randomly devided into transpyloric feeding group(TP group) (n =30) and intragastric feeding group(IG group) (n =30).The frequency of apnoea,weight gain,the time of birth weight regain,feed intolerance,time of reaching full enteral feeding,the incidence of extrauterus-growth retardation (EUGR),motilin,gastrin,the length of hospital stay,necrotizing enterocolitis and duodenal perforation were observed in two groups.Results:The intolerance and time of reaching full enteral feeding were reduced significantly during transpyloric feeding compared with intragastric feeding (P ＜ 0.05).The number of episodes of apnoea was decreased significantly during transpyloric feeding compared with intragastric feeding (P ＜ 0.01).Conclusion:Transpyloric feeding can be used in VLBW infants.

Objective To evaluate the effects of ulinastatin on acute lung injury during ortho- topic liver transplantation(OLT).Methods Twenty ASAⅢ-Ⅳpatients with end-stage liver disea- ses.undergoing OLT were randomly divided into two groups.Ulinastatin group received intravenous infusion of ulinastatin(3?10~4 IU in 100 normal saline)after skin incision and every 4 h thereafter(n =10).Control group received same amount of normal saline instead of ulinastatin(n=10).Blood sam- pies were taken before skin incision,120 min after skin incision,30 min after liver was removed,5 min and 60 min after reperfusion of the graft and at the end of operation for determination of plasma IL-6, IL-8,TNF-?,MDA concentrations and SOD activity.Respiratory index(RI)[P_(A-a)DO_2/PaO_2]was cal- culated before skin incision,30 min after liver was removed,5 min and 60 min after reperfusion of the graft and at the end of operation.After anesthesia was induced,cardiac output,mixed venous oxygen saturation and central venous temperature were continuously monitored during operation.ECG,CVP, SpO_2,P_(ET)CO_2,radial artery and MPAP were also continuously monitored during operation.P_(ET)CO_2 was maintained at 35-40 mm Hg during operation.Blood temperature was maintained above 35.5℃during operation.Results In group C plasma IL-6 and IL-8 concentrations were significantly increased from 120 min after skin incision to the end of operation as compared with the baseline values(P0.05).RI was significantly lower at 60 min after reperfusion of the graft and at the end of operation in group U than in group C(P

Objective To evaluate the clinic efficacy of sufentanil and remifentanil by target- controlled infusion (TCI) combined with propofol in patients undergoing endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA).Methods Sixty patients,ASA Ⅰ ～ Ⅱ,undergoing elective EBUS-TBNA were randomly divided into group S ( sufentanil group),group R (remifentanil group) and group SR (sufentanil + remifentanil group),each group were twenty patients.The anesthesia of all groups is propofol intravenous anesthesia with 2％ lidocaine topical anesthesia,to controll BIS between 50 and 60 during surgery.Heart rate(HR),mean arterial pressure(MAP) pulse oxygen saturation( SpO2 ) and respiratory rate (RR) were recorded and compared 5mins after entering room(T0),30mins after the beginning of surgery(T1 ) and after surgery(T3).Arterial blood gas and the times of cough during surgery were also recorded and compared in all groups.The use of propofol and lidocaine,the wake-up time,satisfaction with anesthesia and adverse reactions in 6 hrs after surgery were also obtained.Results ( 1 ) RR decreased distinctly in group R and PaCO2 increased distinctly in group S and group R compared with that of group SR (P ＜0.05) during surgery.(2)The times of cough and the wake-up time lessened distinctly in group R and group SR compared with that of group S ( P ＜0.05 ).(3) The use of propofol and lidocaine,satisfaction with anesthesia and adverse reactions in 6 hrs after surgery were similar in all groups ( P ＞ 0.05 ).Conclusion Sufentanil compounded remifentanil by TCI combined with propofol is a safe and feasible anesthesia option for EBUS-TBNA,which provides better efficacy,high satisfaction and less side effects compared with using alone of sufentanil and remifentanil respectively.

In this study, plate transparent circle by Davis method was introduce firstly screening ?-Rhamnosidase high-yield strain. The spore-sprouted Aspergillus niger 8-hour were mutagenized by ethyl methane sulphonate and pre-screened via transparent circle. 11% mutants yield 40% higher of ?-rhamnosidase than the original strain. A high-yield strain, T-226 with the highest ?-rhamnosidase activity of 373.4 U/mL was finally selected from these potential high-yield mutants after rescreened by shake flask fermentation twice. When the T-226 strain was fermented in 5 L bioreactor, the enzyme activity could reach to 631.9 U/mL after 84 h. Thus, the established screening method is highly efficient to isolate ?-rhamnosidase high-yield mutant of A. niger.

There were significant increase in urine protein excretion,raised malondialdehyde(MDA) level and expressions of NF-?B,p22phox and p47phox in renal tissue,and significant decrease in reduced glutathione,superoxide dismutase,vitamin C and E levels in type 2 diabetic Goto-Kakisaki rats after 12 weeks. There was obvious histomorphologic change in the kidneys.All the above indices were improved by intraperitoneal injection of?-lipoic acid(35 mg/kg q.o.d).Besides,significant positive correlations were found of MDA level to p22phox,p47phox and NF-?B in the renal tissue,?-lipoic acid seems to protect the diabetic kidney in this diabetic rat model via antioxidative effects.
