China Medical Equipment 2017;14(9):116-119
Objective:To design real-time transmission system for pre-hospital emergency electrocardiogram(ECG) so as to provide specialty and accurate diagnostic analysis about ECG before patient achieved at hospital and to shorten the waiting time for diagnosis and treatment after they achieved at hospital.Methods: 4G network and virtual private dial-up network(VPDN) were used to real-time transmit ECG data of patient from ambulance to hospital so as to doctors of ECG department and emergency room can analyze the detecting reporter, choose plan of emergency guidance and prepare operation and treatment for patientsaccording to the received ECG data in time.Results: The situations of emergency patients have been grasped and been primarily confirmed before they achieved hospital, therefore, the doctors could made relative preparation for fast and specially treating patients after they once achieved hospital.Conclusion: The real-time transmission system of pre-hospital emergency ECG can remedy the shortage of technical strength of pre-hospital emergency team, and shorten the treating time of emergency patients, and increase the success rate of rescue.

The Journal of Practical Medicine 2016;32(7):1073-1076
Objective To establishment the model of angiotensin Ⅱ (AngⅡ) inducinged cardiomyocyte hypertrophy in H9c2 myocardial cells, and observinge the the changes of ubiquitin binding protein leveljunction protein ubiquitination level. Methods Myocardial cell isolated and subcultured H9c2 were cultured in vitro andmyocardial cell, they were divided into three groups in different AngⅡ concentration (10-8, 10-7, 10-6 mol/L), with in different hours (0, 6, 12, 24, 48, 72 h), and there is also a control group; measured the total protein contentlevel were measured useby BCA method , measured the number of cardiomyocytes in the same area were measured, and the relative surface area of myocardial cells were calculated. The expression of ubiquitin binding protein cardiomyocyte hypertrophy was time- and concentration-dependently induced by AngⅡ, wheremanifested, as total cellular protein content,relative cell surface area and the expression of ubiquitin binding proteinubiquitinated desmin significantly increasing compared with the control group (P < 0.05), which were most significant in 10-7 mol/L AngⅡtreated group for 48 h. Conclusions Cardiomyocyte hypertrophy model induced by 10-7 mol/L AngⅡ for 48 h , was successfully established , where H9c2 cardiomyocyte hypertrophy was induced by 10-7 mol/L AngⅡ in 48 h, and ubiquitin binding proteinubiquitinated desmin significantly increased in cardiomyocyte hypertrophy.
4.The effect of MPCNL in treatmentof complex proximal ureteral calculi
Chinese Journal of Primary Medicine and Pharmacy 2012;19(12):1797-1798
Objective To explore the effect of MPCNL in the treatment of complex proximal ureteral calculi.Methods 90 cases were involved in treatment of complex proximal ureteral calculi in our hospital.MPCNL group were 45 cases and U RL group surgery were 45 cases.Results The operation time,bleeding,single surgery success rate,stone-free rate after surgery success for URL and MPCNL were(34.8 ± 10.5) minutes and ( 112.5 ± 12.4) minutes,(12.5 ± 4.6)ml and (51.3 ±3.7)ml,71.1% and 95.6%,91.1% and 97.8% respectively(P < 0.05).Conclusions The operntive time of URL is shorter,blood loss of URL is less than those of MPCNL,but the success rate of surgery and stone-free rate of URL is not higher than those of MPCNL.Both treatment methods are safe and reliable without serious complications.
5.Advances in the treatment of West syndrome with hormonal therapies
International Journal of Pediatrics 2021;48(3):186-190
West syndrome is one of the most common refractory epileptic syndromes with onsets mostly in infancy.The prognosis is generally poor.The morbidity rate reported in the literature is 0.2‰ to 0.5‰.Hormonal therapies(Adrenocorticotropic hormone and glucocorticosteroid)are recommended as preferred treatment options for West syndrome.It can effectively control spasms, ameliorate recognition impairment, and improve developmental outcomes.The incidence of side effects after hormonal therapy are high, and irritation, hypertension and infection are frequently reported.In this paper, advances in therapeutic mechanism, usage and dosage, short-term effectiveness, long-term effectiveness, prognosis and adverse effects of hormonal therapies are reviewed.

Objective To study the effect of capsule deficient strains CAP64 on apoptosis of mice microglia cell line (N9) cell in vitro . Methods N9 cells were co cultured with CAP64, the flow cytometry was employed to detect the N9 cellular apoptosis on different phase. Results The average apoptotic index of N9 after cultured for 2、4、8、16、24 hours with CAP64 were 9 33%、12 93%、15 37%、16 30% and 20 5%, respectively.

10 mm in diameter and tended to be correlated with the main discharges in EEG in two cases. 11 of 20 cases (61.11%) were effective with AEDs. After more than one year following up, 3 of 10 patients became worse.Conclusion Seizures in TS usually begin in young children, and partial seizures is the commonest seizure type in this study. There is a shift in seizure type during the clinical course. The results also suggests that there is a certain correlation between the size of cortical tubers and the epiletogenic focus. Treatment with AEDs is effective. However, the effect appears decreasing with increasing age.
