Objective To compare the influence between target controlled infusion propofol vein anesthesia and midazolam vein anesthesia toward serum amylase and triglyceride in children with cleft lip and palate.To make a definitude that the feasibility of target controlled infusion propofol used in children′s anesthesia.Methods Sixty children with cleft lip and palate aged from 4 months to 3 years,weighting 6.5-15.9 kg,American Society of Anesthesiologists(ASA)Ⅰ-Ⅱ,were randomly allocated to group P and group M(n=30,each).Group P received target controlled infusion propofol.Anesthesia was induced with target controlled infusion propofol at the target effect-site concentration 3.0 mg/L,remifentanyl 2.0 ?g/kg and vecuronium 0.1 mg/kg.Anesthesia was maintained with a continuous remifentanyl infusion at 0.2 ?g/(kg?min) and vecuronium 0.01 mg/(kg?min) and target controlled infusion propofol at the effect-site concentration 3.0 mg/L.Group M received intermittent boluses of midazolam 0.1 mg/kg.Anesthesia was induced with midazolam 0.2 mg/kg,remifentanyl 2.0 ?g/kg and vecuronium 0.1 mg/kg.Anesthesia was maintained with a continuous remifentanyl infusion at 0.2 ?g/(kg?min) and vecuronium 0.01 mg/(kg?min) and intermittent boluses of midazolam 0.1 mg/kg every hour.The venous blood samples were taken before anesthesia induction(T1),4 hours(T2) and 24 hours(T3) after surgery to measure the serum concentration of serum amylase and triglycride.Results The duration of anesthesia induction,extubation and emergence were shorter in group P compared with group M(Pa0.05).Conclusions The serum concentration of triglyceride may increase because of the stress of anesthasion and operation,and can be higher during target controlled infusion propofol,but does not exceed the normal value.The serum amylase concentration does not increase during target controlled infusion propofol in children.

Objective To compare vacuum-assisted excision with periareola incision surgery for benign breast cancer.Methods One hundred and twenty one patients with benign breast nodules treated in our hospital from October 2014 to October 2015 were enrolled in the study,including 58 cases received vacuum-assisted excision (study group) and 63 cases received periareola incision surgery (control group).There were no differences in age[(30.2 ±5.4) vs.(32.1 ±6.2) years] and tumor diameter[(1.3 ±0.4) vs.(1.5 ± 0.3) cm] between two groups.Results There were no severe complications in both groups.Compared with the control group,the operation time was shorter] (20.4 ±4.7) vs.(48.2 ± 15.4)min,t =3.165,P =0.006],intraoperative blood loss was less [(18.4 ± 5.7) vs.(17.2 ± 3.7) ml,t =-0.297,P =0.672],malformation rate was lower [5.2％ (3/58)vs.22.2％ (14/63),x2 =7.27,P =0.007],incidence of postoperative hematoma was higher [20.7％ (10/58) vs.6.3％ (4/63),x2 =3.502,P =0.041],and the cost of surgery was more expensive(5 100 ± 300) vs.(3 400 ± 1 200) Yuan,t =2.181,P =0.023].Conclusion Comparing with conventional periareolar incision surgery,the vacuum-assisted excision has its advantages and disadvantages for treatment benign breast tumors,and two surgical modalities can be chosen accordingly.

Understanding of the classification of intracerebral hemorrhage may help to better manage the patients with intracerebral hemorrhage.Selecting the appropriate diagnosis and treatment measures as well as preventive strategies for different subtypes in order to improve the prognosis of intracerebral hemorrhage and prevent the recurrence.This article reviews the present common classification methods of intracerebral hemorrhage studied and reported in the world.

Objective To explore a novel operative management for irreducible atlantoaxial dislocation. Methods Fifty-four patients, which as 32 males and 22 females aged from 7 to 63 years old with a mean of 32 years, were diagnosed with irreducible atlantoaxial dislocation, including 18 patients with os odontoideum, 22 occipitalization, 5 malunion of odontoid fracture and 9 relaxation of transverse ligament of atlas. Forty patients presented signs and symptoms of myelopathy or spinal cord injury. All of the patients underwent the operation of open reduction and release by transoral approach. The longus collies muscles, longus capitis muscles, anterior longitudinal ligament, atlantoaxial articular capsules, the apical odontoid ligament and alar odontoid ligaments may be included, were transected, followed by arthrodesis via posterior approach in one stage. Different methods of posterior arthrodesis were conducted as followed: C1,2 transarticular screw fixation in 5 cases, occipitocervical fixation using pedicle screws of axis and occipitocervical plate in 37 cases, and C1,2 joint fixation with plates and screws in the lateral masses of the atlas and axis in 12 cases. Results A complete reduction was achieved in 41 cases, and the other 13 patients obtained partial reduction. Forty-eight patients were followed up from 4 to 40 months, 15.7 months at the average. All of them achieved solid arthrodesis. According to Odom's scoring system, among the 38 patients with preoperative upper cervical myelopathy, 15 patients were assessed as excellent, 14 good, 8 fair and 1 poor. During the operation, cerebral spinal fluid leakage occurred in 1 case, and pedicle screwing failed in 1 case. After the operation, respiratory failure was found in 1 case, nasal sound in 3 cases, dysphagia in 1 case. One patient became quadriplegia due to myelitis caused by septicemia at two weeks after the operation. The internal fixation loosened in 1 case at 2 months postoperatively. Conclusion Transorally surgical release for reduction and posterior arthrodeses could achieve satisfactory outcomes in patients with irreducible atlantoaxial dislocation.

Objective To assess the value of serum N terminal pro-brain natriuretic peptide(NT-Pro-BNP) in the diagnosis of congestive heart failure(CHF) and evaluation of cardiac function in children with ventricular septal defect (VSD).Methods Fifty one children were enrolled from March 2004 to March 2005.NT-Pro-BNP was measured by enzyme immunoassay technique.At the same time,left ventricular ejection fraction(LVEF) and left ventricular shortening fraction(LVFS) were detected with echocardiography.Results The data of NT-Pro-BNP were showed but the logarithms of which were normal distribution.The values of NT-Pro-BNP were developed successively along with the severity of cardiac function.But there was no difference between the group of no heart failure and mild heart failure.But the values of LVEF and LVFS had no differences in the control,the mild and the moderate heart failure and the same time all of which beyond the standard of diagnosing heart failure.NT-Pro-BNP could reflect the degree of heart failure or cardiac function (r=0.826).But LVEF and LVFS can not reflect the degree of the cardiac function.Conclusions NT-Pro-BNP can reflect the degree of the cardiac function in VSD,and the degree of the heart failure can be classed by the levels of serum NT-Pro-BNP.But the value of LVEF and LVFS can not reflect the degree of the heart failure in the same disease.

Objective To investigate the effect of microcatheter in chemoembolization of HCC. Methods Using 4-F ～ 5-F Yashiro/Kouno and 5-F Hook catheters as guiding catheter,3-F microcatheter was put into segmental hepatic artery or tumor feeding artery and chemoembolization was carried out. Results All 35 cases had 50 times chemoembolizations totally, of them, 16 cases with small HCC had segmental TAE and 19 cases with large but localized HCC had right/left hepatic artery or anterio/posterio brtaneh of right hepatic artery embolization,1 ～2 year survial rates were 100% ,87.5% and 52.6% ,42. 1% respectively after TAE. Liver function damage after TAE was slight and no complications occurred. Conclusion Improving embolization precision by using microcatheter is valuable in the cases with small HCC or large but localized HCC with tortuous hepatic artery,hepatic artery stenosis after injury and variations.

Corynebacterium glutamicum SA001 is a mutant with lactate dehydrogenase (ldhA) deletion. In order to increase metabolic flux from isocitrate to succinate, and to improve the production of succinate under anaerobic conditions,we transducted the gene aceA coding isocitrate lyase (ICL) from Escherichia coli K12 into Corynebacterium glutamicum SA001 (SA001/pXMJ19-aceA). After 12 h aerobic induction by adding 0.8 mmol/L of IPTG, the recombinant strain was transferred to anaerobic fermentation for 16 h. Succinate reached 14.84 g/L, with a productivity of 0.83 g/(L x h). Compared to C. glutamicum SA001, the activity of ICL of the recombinant strain was increased 5.8-fold, and the succinate productivity was increased 48%. Overexpression of isocitrate lyase will increase the metabolic flux of glyoxylate bypass flowing to succinate.
