Objective To compare the T-lymphocyte subpopulations,complement C3,C4 and HBV-DNA in the peripheral blood of patients with chronic hepatitis B under different liver function.Methods A total of 136 patients with chronic hepatitis B were selected,the patients were divided into improved group and deteriorated group according to the changes of hepatic function.T-lymphocyte subpopulations,complement C3,complement C4 and HBV-DNA in two groups were determined.Results A total of 72 patients were included in improved group,64 patients were included in deteriorated group.CD4+ in deteriorated group was significantly decreased,and CD8+ was significantly increased compared with those in improved group(P<0.05),CD3+ had no statistical difference between the two groups(P>0.05).Complement C3 and complement C4 in deteriorated group decreased compared with those in the improved group(t=12.124,P=0.003;t=4.041,P=0.010).However,HBV-DNA had no statistical difference between two groups(t=-2.598,P=0.793 ).Conclusion Compared with T-lymphocyte subpopulations,complement C4 and HBV-DNA,complement C3 has a better sensitivity to reflect the damage of the hepatic function in patients with chronic hepatitis B.

Objective This study aimed to discuss the different assessment of pain among medical and nursing staff and cancer patients and supply reference for proper analgesic precept for clinical application and nursing measures. Methods We collected the assessment of psychological pain and physiological pain by 55 hospitalization cancer patients, 40 physicians in-charge and 55 nurses in-charge in one week by Johnson inventory. The assessment results were compared and at the same time the relevant problems of the attitude to cancer pain by patients was also investigated. Results Improper recognition existed in cancer pain treatment by most cancer patients. The physiological pain was higher than the psychological pain assessed by both patients and nurses (P<0.05). But the pain assessment by patients was higher than that by the nurses (P<0.05). The assessment of psychological pain was higher than the physiological pain by doctors and both aspects were lower than those by patients, but no statistical difference was seen (P>0.05). The assessment by doctors was more accurate than that by nurses. Conclusions Routine establishment of pain assessment inventory for patients could instruct patients how to record the degree of their pain. We should strengthen the standard training about pain management knowledge and give timely communication with patients' cancer pain.

Objective To analyze the diagnostic value of fluorescence polarization assay (FPA) for human brucellosis.Methods From April 2013 to August 2014,240 positive sera of brucella patients were collected as case group and 287 normal sera as control group in Heilongjiang Agricultural Reclamation Bureau General Hospital.Four milliliters of venous blood were withdrawn for separation of serum.Fluorescence polarization assay was used and the consistency,sensitivity and specificity were compared with those of four classical serological methods,including rose bengal plate agglutination test (RBPT),standard tube agglutination test (SAT),Coomb's test and cysteine test.Results The results of FPA were complied with those of the four conventional serological methods,Kappa ≥ 0.75.The sensitivity of FPA (89.17％) was higher than that of RBPT (87.08％),SAT (85.00％),Coomb's (74.17％) and cysteine test (75.83％).The specificity of FPA (94.08％) was higher than that of RBPT (89.90％) and Coomb's (81.53％),but lower than that of SAT (98.95％) and cysteine test (99.30％).Conclusion FPA can be used as a laboratory diagnostic method for human brucellosis,which is worthy to be widely used.

Objective To indentify the cognitive status of Chinese patients to acne and the influencing factors to theirs' cognitive status,so as to provide solid evidences for the prevention and treatment of acne.Methods A self-designed questionnaire was made to conduct this survey of 16,156 acne patients,who seeked to the treatment in the dermatological departments from 112 hospitals in China.The survey consisted of several parts,including the general status of patients,the patients' cognition of occurrence,development and risk factors of acne,whether the first choice was seeking treatment at the hospital when the patients had acne and the condition of selection of skin care products.The factors were analyzed,which could impact the cognition of the patients' behavior of treatment,how did the patients' cognition to influence their medical behavior and skin care as well as the consistency of assessment of the severity of acne by doctors and patients themselves.Results The acne patients studied had the best knowledge of "acne is a skin disease","it not only occurs in the period of adolescence" and "the disease can be prevented and cured",which accordingly accounted for 80.65％,69.16％ and 65.49％ of the total patients respectively.However,the awareness of acne patients to heredity,high sugar and dairy products as risk factors for acne was insufficient,which accounted for 48.72％,42.40％ and 18.25％ of the total patients,respectively.Gender,age,educational level,occupation and health knowledge were the main factors affecting the cognitive level of patients;the survey also found that men,patient with educational level of junior high or even lower educational condition,occupation of labor workers or farmers and patients were lack of health education with poor knowledge of the genetics and dietary were risk factors for acne;patients with age over 36 years or with mild illness had poor knowledge of dietary risk factors for acne;the difference was statistically significant (P＜0.05).The analysis of the influence of cognitive status on medical treatment behavior and skin care showed that the better the cognition,the higher the probability of patients would choose medical treatment as the first choice as well as choosing functional skin care products;the difference was statistically significant (P＜0.05).The consistency of assessment of the severity of acne by doctors and patients was poor (Kappa value ＜0.4),and the assessment of severity of acne by patients was more serious than doctors' assessment.Conclusions Patient's cognitive status will affect their medical behavior and skin care,and there is also a phenomenon that patients have a more serious assessment of their acne condition.It is suggested that health education for acne patients should be strengthened in clinical medicine so as to improve their knowledge of acne as well as preventing from acne effectively.
