The Journal of Practical Medicine 2015;31(15):2524-2526
Objective To investigate theeffect of the one-lung ventilation (OLV) on open heart surgery with right subaxillary minimally invasive small incision in infants. Methods We conducted a retrospective analysis of 316 infants undergoing open heart surgery through right axillary straight mini-thoracotomy in ourhospital from Jan-uary 2014 to December 2014. Ordinary tracheal tube was inserted into left bronchus during OVL in all patients. OLV with pressure-control mode was performed with FiO2 100% and I:E 1:1 ~ 1.5 and their respiratory rate and the pressure ventilation were adjusted to maintain SpO2 and ETCO2 in the normal range. Conventional ultrafiltration was performed after CPB and fluid restrictions were intraoperatively maintained. Blood samples were obtained for deter-mination of PaO2 and PaCO2 after induction of anesthesia (T1), at the time points: OLV 10 min (T2), OLV 30 min (T3), OLV10 min after CPB (T4) and the recovery TVL (T5). The HR, MAP, incidence of pneumothorax and me-chanical ventilation time were recorded and monitored as well. Result All patients lived through perioperative pe-riod, without pneumothorax. There were no significant differences in PaCO2, HR and MAP between time points. But PaO2 at the time point of T1 significantly lowerthan those at other time points of T2, T3, T4 and T5, but its indexes at all time points were in normal range. Conclusion The appropriate skills ofintubation, rational strategy of ventila-tion and intensive prevention of the lung may be good for the safe application of OVL in open heart surgery through right subaxillary minimally invasive small incision in infants.

3.Clinical research progress of distal tibial fracture in surgical treatment
China Medical Equipment 2014;(9):82-84
Distal tibial fractures (Distal tibial fracture) is a common clinical fractures type, more for high-energy damage, fracture type is more complicated. Because of the distal tibia special anatomic structure (soft tissue is less, less blood supply), if the operation method is not suitable or fixed equipment selection is not reasonable, because fracture healing, osteomyelitis, also can damage the function of the ankle joint. Treatment shall be based on the fracture position, type, in the process of the polluted situation and surrounding soft tissue trauma injury and so on many factors that determine the way and the internal fixation methods. This paper reviews recent year different types of distal tibial fracture fixation and fixed ways of literature research, in the treatment of distal tibial fracture clinical practice to provide the reference of objective reasonably select fixation and evaluation standard.
4.Content Determination of Chloramphenicol and Salicylic Acid in Acne Tincture by HPLC
China Pharmacy 2015;(18):2557-2558,2559
OBJECTIVE:To establish a method for the content determination of chloramphenicol and salicylic acid in Acne tinc-ture. METHODS:HPLC method was adopted with the column of Shim-pack CLC-ODS with the mobile phase of methanol-water (50∶50,V/V)at the flow rate of 0.8 ml/min. The detection wavelength was 278 nm,column temperature was 35 ℃,and the vol-ume was 10 μl. RESULTS:The linear range was 2.0-10.0 μg/ml(r=0.999 2)for chloramphenicol and 5.0-25.0 μg/ml(r=0.999 1) for salicylic acid;the RSDs of precision,stability and repeatability tests were lower than 1%;the average recoveries chlorampheni-col and salicylic acid were respectively 99.77%(RSD=0.35%,n=9) and 99.29%(RSD=0.48%,n=9). CONCLUSIONS:The method is simple,rapid,accurate,specific,precise,and can be used for quality control of Acne tincture.
5.Study on cellular deformation of in vitro osteoblasts' shear stress loading experiment and their mechanotransduction region
International Journal of Biomedical Engineering 2010;33(6):340-342
Objective To study the main mechanotransduction area and to estimate the overall shear deformation of rat osteoblasts in shear stress loading experiment based on data acquired from the in vitro rat osteoblast experimental, and to study the effects of four-point bending medium flow generated shear stress on cells. Methods Viscoelastic mechanics theory was used in the calculation process, the standard viscoelastic model was adopted for cells, and shear force on the cellular surface was simplified to be uniform. Results The cellular deformation caused by shear force was about one-tenth of that from tensile loading experiment which induced equivalent biological response. Conclusion In terms of mechanical stimulus induced biological responds, the mechanical transduction caused by cellular deformation in shear stress loading experiment is negligible, and the main transduction area is in the cellular membranes experiencing shear stress.
6.Intra-arterial recanalization for acute ischemic stroke
International Journal of Cerebrovascular Diseases 2010;18(5):342-346
Intra-arterial recanalization may rapidly restore blood flow and salvage the ischemic penumbra,which has become the most effective therapeutic means for acute ischemic stroke. Many noel revascularization therapies have been used in clinical practice. This article reviews the advances in this field.

The synthesis of cellular and nuclear basic proteins in the first generation of the repopulated pachytene spermatocytes (RPS) after the withdrawal of gossypol treatment and the normal control pachytene spermatocyte (CPS) were studied by the incorporation of ~3H-arginine into proteins. After treatment with gossypol for various periods of time, the synthetic activity for cellular protein in the RPS was slightly inhibited. In comparison to CPS, the inhibitory rate ranged from 12% to 26% (gossypol treatment for 3 to 12 weeks, respectively). However, the synthetic activity for nuclear basic protein in the RPS was drastically reduced in comparison to that of the CPS. The reductive rate ranged from 46% to 61% in RPS (gossypol treatment for 3 to 12 weeks, respectively).Gel electrophoretic separation of the basic protein extracted from normal pachytene cell indicated that the major basic proteins were nucleosomal linker and core proteins, i. e., histone H_1, H_(2a), H_(2b), H_3 and H_4, and with a lesser amount of spermspecific BP and X_1 proteins. In the RPS, the synthesis of sperm-specific proteins(BP and X_1) and core histones (H_(2a) and H_4) reduced markedly.Finally, the effect of gossypol on the ratio change of nuclear basic protein to DNA in RPS and its relation to nucleosomal spacing and chromatin structure are discussed.

Objective To evaluate the effect of bone marrow stem cells (BMSCs) transplantation in the treatment of hepatolenticular degeneration of liver fibrosis. Methods Sixty cases with confirmed hepatolenticular degeneration of liver fibrosis were randomly divided into 3 groups: penicillamine group [40 mg/(kg·d)], BMSCs group and BMSCs + penicillamine group. Autologous BMSCs (2 mL) were injected into vein with normal saline (100 mL). Liver tissue pathology biopsy was inspected and the changes in HA, PCⅢ, LN, CⅣ, TIMP-1 and MMP-1 were observed at 0, 4th, 8th and 12th week during the therapeutic process. Results The level of serum fibrotic markers were reduced in every group , while the changes in BMSCs + penicillamine group were especially obvious (P < 0.05). Conclusion Penicillamine combined with BMSCs was effective in the therapy of hepatolenticular degeneration of liver fibrosis.
