Chinese Journal of Primary Medicine and Pharmacy 2012;(23):3521-3522
Objective To investigate the evaluation of serum cystatin C and treating efficacy of enalapril for contrast induced nephropathy after percutaneous coronary.intervention.Methods 86 patients who need coronary angiography or coronary stents implantation by skin were divided into observation group(43 cases)and control group(43 cases)randomly.The fasting venous blood was extracted and in which Cys-C and Scr were tested.All the patients were given water therapy,and enalapril was added in observation group.Diversification of concentration of Cys-C and Scr and efficacy of enalapril were recorded.Results There was no difference of Cys-C and Scr in serum and eGFR before and after operation(all P>0.05),and the concentration of BUN was(3.96±0.89)mmol/L,which was lower after operation(P<0.05),and the rate of CIN incidence was 2.33 %(1 case).The concentration of Cys-C in serum was(18.4±0.58)mg/L,which was significantly higher than preoperation(P<0.05),and there was no significant difference of Scr,eGFR and BUN before and after operation(P>0.05),and the rate of CIN incidence was 11.63%(5 cases).Conclusion Cys-C was more sensitive in early detection for contrast induced nephropathy and more convenient.The rate of CIN incidence could be decreased by using enalapril.
2.Acute Lymphoblastic Leukaemia In A 7-year-old Presenting With Lower Limb Pain – Not Just Your Simple Growing Pains!
The Singapore Family Physician 2020;46(7):32-35
This is a case report of a 7-year-old boy who presented with lower limb pain. He was initially presumed to have growing pains but was subsequently diagnosed with
acute lymphoblastic leukaemia (ALL). This case highlights the important clinical presentations and differential diagnoses of ALL that a family physician should be cognizant about to avoid misdiagnosis. It also demonstrates the importance of understanding the patient and family's perspectives when evaluating a child with lower limb pain. This enables us to anticipate
and meet their needs.

5.Study on TPS Dose Distribution of Radiation Therapy with Wedge for Upper-thoracic Esophageal Cancer
Chinese Medical Equipment Journal 1989;0(02):-
Objective To study the TPS dose distribution of the radiation therapy with wedge for upper-thoracic esophageal cancer.Methods Adopting spiral CT scanning,three dimensional data of the focus of infection and the other tissues were acquired.The radiotherapy plans with 45? wedges and without wedge were designed in TPS.The dose-volume histogram were calculated and compared.Results Although the average of dose of irradiated target was very close in the two plans,but there was remarkable difference in the dose uniformity.The Std(standard deviation) of dose in irradiated target was 6.31 in plan without wedge,and it was 4.45 in plan with the 45? wedge.The results show that the dose distri-butions of irradiated target are optimized by using the wedge.Conclusion It is a simple and effective method to use wedge for improving dose distribution in the radiation therapy for upper-thoracic esophageal cancer.
6.Prognostic value of first documented rhythms in patients with in-hospital cardiac arrest
Chinese Journal of Emergency Medicine 2017;26(2):202-205
Objective To evaluate the prognostic value of the first documented rhythm in patients with in-hospital cardiac arrest.Methods The clinical data of 62 in-hospital cardiac arrest patients collected from May 2011 to April 2016 were reviewed.Multiple regression analysis was performed for determination of the factors relevant to ROSC.The patients were divided into defibrillative rhythm group [ventricular fibrillation (VF) /ventricular tachycardia (VT)] and non-defibrillative rhythm group [pulseless electrical activity (PEA) /asystole] according to the first documented rhythm after cardiac arrest.The differences in rate of restoration of spontaneous circulation,number of survival at hospital discharge and those discharged with favorable neurological outcome were compared between groups.Results Logistic regression analysis showed that non-defibrillative rhythm was related to low rate of ROSC.Rate of ROSC (x2 =6.90,P =0.01),number of survival at hospital discharge (x2 =10.49,P =0.00) and those discharged with favorable neurological outcome (x2 =14.70,P =0.00) were higher in the defibrillative rhythm group,while there was no difference in outcomes between the VF and VT groups.There was no difference in consequence found between the PEA and asystole groups.Conclusion Rate of restoration of spontaneous circulation,number of survival at hospital discharge and those discharged with favorable neurological consequence were higher with defibrillative initial rhythm.

9.Analysis on Quality Control of Conformal Radiotherapy for Nasopharyngeal Carcinoma
Chinese Medical Equipment Journal 2003;0(11):-
Objective To analyze the quality control of the conformal radiotherapy for nasopharyngeal carcinoma. Methods Using BJ-6 6MV linear accelerator, STAR -2000 3D TPS and immobilization device, the patient of nasopharyngeal carcinoma were treated by the conformal radiotherapy. Results Adopting individualized compatibly-shaped face masks and CT scanning (2mm interval, 2mm thickness), three dimensional data of the target and the other tissues were acquired. The conformal radiotherapy was designed in planning system. At the treatment, the target volume was put on the isocenter of the linear accelerator by the customized patient positioning. Conclusion Because the nasopharyngeal carcinoma is located in a special area and it is surrounded by some important organ, in the conformal radiotherapy, the quality control of the CT immobilization technique and the customized patient positioning is very important. This can ensure effective and safe irradiation for the small target volume while excessive irradiation is avoided in other surrounding organs.

Chinese Traditional Patent Medicine 1992;0(06):-
AIM:To study the detection limits of aristolochic acid in Herba Asari preparation by HPLC. METHODS: Whether Asarum hetertropoides Fr.Schmidt ver.Mandshuricum(Maxim.) Kitag contained aristolochic acid A or not by HPLC and MS,and the difference in the reference substance and the sample solution was compared. RESULTS: Aristolochic acid A could not be found in A.hetertropoides Fr.Schmidt ver.Mandshuricum(Maxim.)Kitag by HPLC,but be found by MS. CONCLUSION:A.hetertropoides Fr.Schmidt ver.Mandshuricum (Maxim.)Kitag contained trace aristolochic acid,but it is difficult to measure aristolochic acid in Herba Asari by HPLC.The baseline noise of the sample solution can interfere with the detection limit of the trace compound compound
