1.Portable instrument for arteriosclerosis assessment.
Chinese Journal of Medical Instrumentation 2014;38(1):6-10
A portable instrument for arteriosclerosis assessment containing sensor module, acquisition board and embedded module was developed for home care in this paper. The sensor module consists of one ECG module and three pulse wave extraction modules, synchronously acquiring human ECG and pulse wave signal of carotid, radial, and dorsal, respectively. The acquisition board converts the sensor module's analog output signals into digital signals and transmits them to the embedded module. The embedded module realizes the functions including signal display, storage and the calculation and output of pulse wave velocity. The structure of the proposed portable instrument is simple, easy to use, and easy to expand. Small size, low cost, and low power consumption are also the advantages of this device. Experimental results demonstrated that the proposed portable instrument for arteriosclerosis assessment has high accuracy, good repeatability and can assess the degree of atherosclerosis appropriately.

4.Advances in the study of tumor suppressor genes in gliomas
China Oncology 2001;11(2):181-183
Glioma is the most malignant tumor in CNS, the effect of present therapy is poor. A important discovery in tumor molecular biology is that the activation of oncogene and inactivation of tumor suppressor gene play an important role in the mechanism of tumorgenesis. The advances in the study of tumor suppressor genes in gliomas were reviewed.
5.The effect on pregnancy of counseling the life style from the first trimester based on the fasting hyperglysemia
Chinese Journal of Primary Medicine and Pharmacy 2011;18(15):2037-2038
ObjectiveTo counsel the life style from the first trimester based on the fasting hyperglysemia to decrease the rate of GDM and adverse effect of it. MethodsThe pregnancy women with fasting hyperglysemia were recruited. All subjects were divided into two groups, one was counselled the life style from the first trimester but the other not. The pregnant outcome were compared. ResultsIn the study group 1 100 with complete information and 29 were abnormal glucose intolerance, 1 120 of 47 in control. The rate of GDM or GIGT,hypertensive disease,spontaneous abortion,premature dilivery, polyhydramnios, fetal macrosomia, fetal growth restriction, neonatal respiratory distress syndrome and the mean GHbA1c was lower than that in control ( x2 = 8.110,6.124,5.815,4.518,6.355,3.957,5.453,4.619, t = 3.385, all P < 0. 05 ). But the body mass index at labor( t = 0.698 ), infection disease ( x2 =0.082),mean neonatal weight (t = 2.09 )and neonatal hypoglysemia (x2 = 0.035 )of term labor had no significant differences. ( t = 0.698, χ2 = 0.082,t = 2.090, χ2 = 0.035, all P > 0.05 ). ConclusionCounseling the life style from the first trimester based on the fasting hyperglysemia could decrease the rate of GDM or GIGT and improve the pregnancy result.
6.Adsorption of fentanyl in different materials of analgesia pump reservoir
The Journal of Clinical Anesthesiology 2010;(12):1064-1065
Objective To observe the adsorption of fentanyl by different materials of the analgesic pump reservoir. Methods The concentrations of fentanyl in pump reservoirs,which were made by different materials (glass,silica gel,polyvinyl chloride,non polyvinyl chloride) were detected with the time by high-performance liquid chromatography. The measurement was repeated three times.Results Fentanyl concentration in these reservoirs decreased with time,which decreased 6.3% in silica gel reservoir (P0.05),2.7% in non polyvinyl chloride(P0.05),1.5% in PVC and 1.2% in glass bottles.Conclusion Fentanyl citrate will be adsorbed by different materials of analgesia pump reservoir within 72 h,and the adsorption sequence was silica capsule,non polyvinyl chloride,polyvinyl chloride,and glass bottles.
7.Variations and adaptations of associating liver partition and portal vein ligation for staged hepatectomy with the guidance of damage control surgery
Chinese Journal of Digestive Surgery 2016;15(5):431-437
Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) is used for patients with advanced hepatocellular carcinoma who cannot tolerate major hepatectomy due to an insufficient future liver remnant,but the morbidity and mortality rate in the perioperative period are still high.Available studies indicate that damage control surgery variations such as laparoscopic procedure and associating radiofrequency/microwave ablation/liver tourniquet and portal vein ligation could improve the morbidity and mortality associated with ALPPS,as could portal vein embolization.However,randomized controlled trials are needed to determine benefits in technical variations.

9.Adjunctive efficacy of microbial ecological agents for elderly patients with acute pancreatitis
Chinese Journal of Geriatrics 2013;(6):627-629
Objective To explore the auxiliary efficacy of microbial ecological agents for elderly patients with acute pancreatitis.Methods Totally 144 elderly patients with acute pancreatitis were selected and randomly divided into the observe group and the control group (n=72,each).All patients received the regular treatment and enteral nutrition.Microbial ecological agents were added in enteral nutrition in the observe group.The levels of endotoxin (ET),tumor necrosis factor (TNF-α),interleukin (IL)-6 and C-reactive protein (CRP)in peripheral blood were determined and compared between the two groups.The clinical index and the occurrence of adverse reactions were observed.Results Compared with pretreatment,the levels of ET,TNF-α,IL-6,CRP were significantly reduced in both two groups after treatment.The levels of ET,IL-6,TNF-α,CRP were lower in the observe group than in the control group [(0.14±0.07)EU/ml vs.(0.31±0.12)EU/ml,(44.77±17.82)pg/ml vs.(63.25 ± 14.26)pg/ml,(0.15 ± 0.05)μg/L vs.(0.29 ± 0.14)μg/L,(108.33 ±11.84)mg/Lvs.(135.41±21.45)mg/L,t=14.722,43.824,7.071,5.811,respectively,allP<0.05].The recovery time of symptoms and signs,the anal exsufflation time and hospitalization time were shorter in the observe group than in the control group [(25.8±4.8)h vs.(36.4±6.2)h,(30.9±6.7)hvs.(44.4±7.3)h,(24.9±3.2)hvs.(37.6±3.4)h,(6.9±0.4)dvs.(13.1±1.2)d,t=4.747,4.401,10.125,33.443,respectively,all P<0.05].There were no statistically differences in death rate and the occurrence of adverse reactions between the two groups (x2 =0.15,0.64,both P>0.05).Conclusions Microbial ecological agents are safe and effective as an adjuvant therapy for elderly patients with acute pancreatitis.It is worth promoting in clinical medicine.

Objective To determine whether NT 3 overexpression could abrogate DDP toxicity in vitro . Methods We constructed a herpes simplex virus(HSV) amplicon vector to transduce a c myc tagged version of rat NT 3. In the HSVnt 3myc vector, the chimeric neurotrophin cDNA was placed under the transcriptional control of the CMVIE promoter. The resultant vector was packaged utilizing the recently developed helper virus free method. Results Transduction of NT 3myc in cultured mouse cochlear explants at a multiplicity of infection(MOI) of 0 25 resulted in production of NT 3 up to 3?g/L over a 48 hours period. The mouse cochlear explants were transduced with HSVnt 3myc or HSVmiap(control vector expressing the reporter gene, murine intestinal alkaline phosphatase) for 48 hours and the exposed to cisplatin for 48 hours.The cochlear explants transduced with HSVnt 3myc had a significantly greater number of SGN survival than the control group. NT 3 powerfully enhanced the process length and the density of SGNs.Conclusion These data demonstrate that the neurotrophic cDNA transduction via HSV amplicon helper free virus system can attenuate the ototoxic action of DDP on organotypic culture. The potency of NT 3 in protecting spiral ganglion neurons from degenerating suggests that neurotrophins might be useful for the prevention or treatment of hearing disorders. [
