Objective To investigate the relationship between serum hepatitis B virus markers (HBV-M ) and HBV-DNA . Methods Enhanced chemiluminescence enzyme immunoassay (ECLIA ) and real-time fluorescent quantitative polymerase chain re-action(FQ-PCR) were employed to detect HBV-M and HBV-DNA in 262 serum samples ,respectively .HBV surface antigen(HB-sAg) ,anti-HBV surface antibody(HBsAb) ,HBV e antigen(HBeAg) ,anti-HBV e antibody(HBeAb) ,anti-HBV core antibody(HB-cAb) were included in HBV-M .Results Compared the positive rates of HBV-DNA ,HBsAg ,HBeAb in HBeAg-negative patients with those in HBeAg-positive patients ,the differences were statistically significant (P< 0 .01) .29(36 .7% ) patients with HBV-DNA logarithm value not less than 5 were found in HBeAg-negative patients .Differences of HBeAg ,HBeAb positive rates among patients with different ages were statistically significant (P<0 .01) .25 patients with HBsAg less than 250 IU/mL were found in HBV-DNA-positive patients ,12(48 .0% ) of which showed HBV-DNA logarithm value not less than 5 .HBV-DNA logarithm value of HBV-DNA-positive patients was positively correlated to HBeAg and HBeAb (r= 0 .542 ,0 .607 ,P< 0 .01) .Conclusion Com-bined detection of HBV-M and HBV-DNA contributes to estimating the HBV infection .

Objective:To investigate the clinical value of electrocardiogram in risk stratification of patients with non-ST segment elevation acute coronary syndrome(ACS).Methods: According to the change of electrocardiogram, 260 patients with non-ST segment elevation ACS were divided into four groups: ECG-undiagnosed group (n=22), T-wave inversion group (ST-segment depression group), ST-segment depression group (n=118) and normal electrocardiogram group(n=80). All patients were treated with conventional 18-lead electrocardiogram and troponin I(TnI)detection in the four groups. The incidence of cardiovascular events during and after hospitalization was observed. Results: The complex cardiovascular events and recurrent angina attacks in ST segment depression group increased significantly than that in normal ECG group. The difference was statistically significant (x2=5.723,x2=15.680;P<0.05). Multivariate logistic regression analysis showed that TnI positive factors predict the independent value of composite cardiovascular events higher.Conclusion:The patients with ST segment elevation acute coronary syndrome can effectively carry out risk stratification by ECG ST-segment changes and TnI levels, and predict the cardiovascular events. It has higher clinical application value and independent predictive value of TnI positive.

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.
