Objective:To study therapeutic effect of cilazapril and amlodipine on QT interval dispersion and arrhyth-mia in patients with essential hypertension (EH) .Methods:A total of 120 EH patients complicated with ventricular arrhythmia in our hospital from Mar 2011 to Mar 2014 were enrolled ,randomly and equally divided into cilazapril group and amlodipine group ,the two groups all received routine antihypertensive therapy .Blood pressure ,QT in-terval and arrhythmias were compared between two groups .Results:Compared with amlodipine group ,there were significant reductions in 24h mean systolic blood pressure [24hSBP ,(123.81 ± 17.95) mmHg vs .(104.92 ± 14.25) mmHg] ,24h mean diastolic blood pressure [24hDBP ,(88.31 ± 10.28) mmHg vs .(72.24 ± 8.45) mmHg] ,24hSBP variability [ (11.62 ± 1.34) mmHg vs .(7.34 ± 0.97) mmHg] ,24hDBP variability [ (9.47 ± 1.18) mmHg vs .(5.13 ± 0.72) mmHg] ,QT interval [ (385.1 ± 50.4) ms vs .(342.7 ± 48.5) ms] ,corrected QT interval [ (362.7 ± 50.2) ms vs .(321.8 ± 45.1) ms] and QT interval dispersion [ (34.1 ± 5.1) ms vs .(22.5 ± 3.7) ms] in cilazapril group , P<0.05 or <0.01;ventricular arrhythmia class in cilazapril group was significantly better than that of amlodipine group , P<0. 05. Conclusion:Therapeutic effect of cilazapril is more helpful to reduce blood pressure ,QT interval dispersion and improve ventricular arrhythmia than amlodipine in EH patients complicated with arrhythmia .

Objective To analyze the surface-electromyography (sEMG) signals of patients with lumbar disc herniation before and after core stability exercise therapy.Methods Thirty-eight cases diagnosed with lumbar disc herniation were randomly divided into a control group (n =19) and an experimental group (n =19) using a random number table.The former was given two weeks' conventional traction physiotherapy,while the latter was given another two weeks of core stability exercise of lumbar and dorsal muscles after the conventional treatment.All of the patients were assessed using a visual analogue scale (VAS) and each was given a Japanese orthopedic association (JOA) score,sEMGs were recorded before and after 4 weeks of treatment.Results After treatment,average VAS scores[(1.11 ±0.74) and (0.95 ±0.62) respectively] and JOA scores[(21.05 ±3.08) and (23.47 ±2.04) respectively] in the control and experimental group both had improved significantly compared to that before treatment (P ＜ 0.01).The average JOA score in the experimental group was significantly higher than that in the control group (P ＜ 0.01) after the treatment.After treatment of 4 weeks,erector spinae median frequency (MF) values(84.84 ± 12.78) and erector spinae average amplitude (AEMG) value (108.94 ± 24.70) in the experimental group were significantly improved(P ＜ 0.05),so did the multifidus muscles MF value(95.63 ± 16.35) of affected side.There was no significant difference between the affected and unaffected side (P ＞ 0.05).Moreover,the MF values of the experimental group were significantly higher than that the control group (P ＜ 0.05) after treatment.There was significant difference between the average AEMG values of erector spinae of affected side before and after treatment (P ＜ 0.05).Conclusions Core stability exercise can further alleviate the symptoms of lumbar disc herniation after conventional traction physiotherapy.It improves the fatigue tolerance of the back's core muscles and relieves functional imbalance of the multifidus muscles.However,the time of therapy should be lengthened to study its effect on strengthening lumbar muscles.

Henoch-Sch(o)nlein purpura(HSP) is one of the most common vasculitides in children with many manifestations including skin purpura,arthritis,abdominal pain and renal involvement.The renal involvement(Henoch-Sch(o)nlein purpura nephritis,HSPN) is the principal cause of morbidity and major risk factor for prognosis in HSP.The paper reviewed the updated treatment strategy for HSPN.Accordingly,steroids,cyclophosphamide,mycophenolate mofetil,mizoribine,cyclosporine,triptolide,angiotensin converting enzyme inhibitors (ACEI) / angiotensin receptor blockers(ARB),plasma apheresis and tonsillectomy are possible indicator for the further therapy of HSPN.Furthermore,prospective randomized controlled treatment studies on children with severe HSPN would be needed.

Objective To investigate the metabolism of blood glucose and lipid levels in health examination of adults from Hain-an district,Wuhai city,Inner Mongolia and to discuss the preventive and health protection measures.Methods 1 395 adults receiv-ing health examination were enrolled.The glucose and lipid were tested and analyzed.Results The levels of glucose and triglyceride in males were significant higher than that in females,P <0.05.The differences of abnormal rates of each index between male and fe-male,among different age groups were statistically significant,P <0.05 as well.The overall level and abnormal rate of each index increased gradually with age(except HDL-C with irregular fluctuations),P <0.05.Conclusion There are certain abnormal rates in blood glucose and blood lipid levels in those examinees and the rates tend to increase with age.Effective health education needs to be strengthened and the preventive and treatment measures should be set up.

Whole-body PET-CT scanning has been used in the diagnosis and treatment of tumor to providing functional and morphological imaging. As the most widely used semi-quantitative analysis index, the cutoff value of SUV would affect the final diagnosis, therapeutic regimen and prognosis estimation. Therefore, the article reviews the influential factors of SUV, its correction methods, its cutoff values of differential various tumors and the progress of SUV. Although there is no acknowledged cutoff value of SUV in tumor diagnosis, SUV is still an important semi-quantitative index, and its rational and prudent use would increase both of the sensitivity and specificity in tumor diagnosis.

PET-CT, SPECT, and SPECT-CT examinations could lead to inevitable medical exposure for patients, and the radiation dose of this examinations and whether it was harmful to patients have attracted attention from the public and professionals. At the same time, there was still a controversy about whether the biological effect of low dose radiation was useful to human body. The research investigates and reviews the radiation dose of PET-CT, SPECT, and SPECT-CT scans and their biological effects. Under achieved to the demands of clinical conditions, operators should try to reduce the radiation dose of PET-CT, SPECT, SPECT-CT scans for patients. Although PET-CT, SPECT, SPECT-CT scans deliver inevitable radiation, the dose of single examination will not lead to deterministic effect, and even the view of the random effect of linear no-threshold from these scans also have been questioned.

Giving up treatment in ophthalmology is common in our country. Financial difficulty is the main reason of abandoning treatment in ophthalmology. We should make every effort to deal with some patients with ocular diseases who had no light perception at all. Misdiagnosis and wrong therapy ought to be avoided as much as possible in our clinical practice. The giving up treatment of retinoblastoma is relatively common in our country at present time and its early diagnosis and early treatment is very important. Therapeutic giving up treatment is a new concept and eye doctors can make use of it in some special situations in that the disease can be treated effectively.
