1.Revaluation of the stent in the bile duct
International Journal of Surgery 2012;39(5):328-331
It is a consensus to place stent after cutting bile duct in the hepatobiliary surgery in the past.However,as the development of bile physiological research and surgical technique,especially the raise of medical concepts of rapid recovery,the negative effects which are caused by the placement of stent have been taken seriously gradually.Up to now,whether the stent should be placed after the bile duct is cut has no definite answer yet.
2.Clinical study on application of non-invasive and dynamic cerebral edema monitor during perioperative period of cardiopulmonary bypass in infantile congenital heart disease
Chongqing Medicine 2016;45(12):1632-1634
Objective To compare the influence of cardiopulmonary bypass(CPB) on brain injury in the infants with compli‐cated congenital heart disease(CHD) and simple CHD by analyzing and monitoring the perioperative cerebral electric impedance co‐efficient ,serum S‐100βprotein and neuron specific enolase (NSE) .Methods Forty infants with CHD were randomly selected and divided into two groups:the complicated group(n=20 ,13 cases of tertralogy of fallot ,7 cases of transposition of great arteries) and the simple group(n=20 ,8 cases of atrial septal defect ,12 cases of ventricular septal defect) .Blood samples were taken and the cere‐bral electric impedance coefficients before operation(T1 ) ,at 10 min after CPB(T2 ) ,immediately after aortic clamping(T3 ) ,aortic o‐pening(T4 ) ,end of CPB(T5 ) ,at 5 h(T6 ) and 24 h (T7 ) after CPB were measured by the BORN‐BE noninvasive brain edema moni‐tor .Serum levels of S‐100βprotein and NSE were detected by ELISA .Results There was no statistically significant difference in the cerebral electric impedance coefficient ,S‐100βprotein and NSE before surgery(P>0 .05) .The cerebral electric impedance coef‐ficient ,S‐100βprotein and NSE were significantly increased from the beginning to the end of CPB(P< 0 .05) ,and gradually de‐creased after CPB(P<0 .05) .The cerebral electric impedance coefficient ,S‐100βprotein and NSE were obviously higher in the com‐plicated group than those in the simple group at the same time points(P<0 .05) .The cerebral electric impedance coefficient was re‐spectively correlated with S‐100βprotein and NSE .Conclusion The influence of CPB on brain injury in complicating CHD infants is more serious than that in simple CHD infants .The BORN‐BE noninvasive brain edema monitor can be used during CPB periopera‐tive period in complicating CHD infants for conducting the real time monitoring in order to reduce brain damage .
3.Comparison of CGH array and SNP array in preimplantation genetic diagnosis
The Journal of Practical Medicine 2015;(17):2822-2825,2826
Objective To compare two kinds of strategies of preimplantation genetic diagnosis (PGD) to evaluate embryos for reciprocal and robertsonian translocation carriers. Methods A total of 152 PGD cycles for chromosomal translocation were performed from April 2012 to June 2014 , including 60 aCGH-PGD cycles using blastomere biopsy and fresh embryo transfer, and 92 SNP-PGD cycles using blastocyst biopsy and thawed embryo transfer. The diagnosis results and clinical outcome with these two kinds of strategies were compared. Results No significant difference was found in the cycles of no embryo transfer between SNP-PGD and aCGH-PGD. The normal rate in SNP-PGD was 33.8%, which was significant higher than that of aCGH-PGD. The clinical pregnancy rate per embryo transfer in SNP-PGD was higher than that in aCGH-PGD, but the misscarrage rate and embryo damage rate were lower than those in aCGH-PGD. Conclusions The PGD strategy of applying blastocyst biopsy, SNP array, embryo cryopreservation and thawed ET leads to a better clinical outcome. It may be a promising choice for future PGD treatment for carriers with chromosomal translocation.

7.The application characteristics of airway management devices
Chinese Journal of Tissue Engineering Research 2007;11(5):987-989,993
OBJECTIVE: To sum up the advantages and disadvantages as well as application prospects of several kinds of new devices in airway management, including the laryngeal mask airway (LMA), esophageal-tracheal combitubes (ETC),fribreoptic stylet laryngoscope (FOS), video Macintosh intubating laryngoscope system (VMS) and GlideScope(R) videolaryngoscope(GSVL).DATA SOURCES: Using the terms "airway management", we searched Medline for airway management device-related articles, which were published during January 1990 to February 2006 in English.STUDY SELECTION: The materials were firstly selected. Successful rate of intubation, intubation-related complications and incidence in studying tracheal intubation with LMA, ETC, FOS, VMS and GSVL were chosen. Inclusive .criteria: ① Randomized and controlled study of adult cases. ② Clinical studies or case report. ③ Including the studies of general airway or difficult airway. Exclusive criteria: ① Study of intubation in children. ② Repetitive study.DATA EXTRACTION: Eighty-six articles about tracheal intubation with LMA, ETC, FOS, VMS and GSVL were chosen, among which, 36 were included in this study, and 50 were excluded due to study on intubation in children or repetitive study.DATA SYNTHESIS: Correct placement does not affect vocal cord movement, so patients may vocalize while an LMA is in place. Its successful rate is over 90%. Its most attractive advantages are increased speed and ease of placement by both inexperienced personal and experienced anesthesiologists, low frequency of cough and low incidence. The esophageal tracheal combrtube is a supraglottic airway device that functions as an effective alternative to ventilization via mask and tracheal intubation in both the esophageal and tracheal position. It is successful when emergency occurs, but it is only suitable for adults. The flexibility of FOS allows for intubation of patients, without the need for head and neck manipulation. The main disadvantages of FOS are their limited field of view and the high cost of purchase and maintenance. Observation and manipulation in using VMS can be performed in one axis. GSVL provides a clear view of larynx on the monitor instead of directly viewed by the operator.CONCLUSION: These new devices of airway management can relatively decrease the intubation difficulty, increase the successful rate and lead to lower complication incidence. The skills of these new airway management devices should be included in the modern anesthesia residency program.
8.CHRONIC TOXIC PATHOLOGIC INVESTIGATION OF FLUOROCARBON BLOOD SUBSTITUTE
Academic Journal of Second Military Medical University 1981;0(03):-
Fluorocarbon emulsion, a substitute of blood, 20 ml/kg were injected once into dogs intravenously. As a result, part of the substitute deposited in the lympho-retic-ular system and was phagocytized by fixed and free histiocytes (rnonophagocytic system), and the histiocytes then converted into foaming cells.One month after injection, the fluorocarbon's deposits in the foaming cells remained at the peak level in the liver, spleen and other organs of the lympho-reti-cuJar system. After six months,no deposits could be found in all viscera and no signs of any pathological changes, except the spleen under a light microscope.After twelve months, no foaming cells were found in the spleen, liver, and kidney under light cmicroscope,yet but foaming cells could be found in the spleen and liver with the help of an electron microscope and we believed that this sign had no pathological significance in clinic practice.The target cells only showed the action of phagocitizing and depositing.According to our observation, the fluorocarbon emulsion is a non cytoplasmic toxin and an inert biologic substance, so there are no secondary histo-pathologic changes caused by fluorocarbon deposition. It seems that 20 ml/kg of fluorocarbon emulsion (equal to 1200 ml for adult human)injected intravenously is rather safe.
