The cognitive conflict between doctors and patients mainly manifests in the different cognition of diseases,the expectation of medical skill and the understanding of medical science.The way to dissolve the cognitive conflict between doctors and patients lies in strengthening exchange and communication between them.

Objective To investigate the infectious state and drug resistance of Haemophilus par lainfluenzae in respiratory tract infection, so as to instruct the rational use of antibiotics. Methods Haemophilus par lainfluenzae were isolated from the pa-tients with respiratory tract infection and performed by K-B methods. Nitrocefin slip test was applied into detecting β-lactamase. Re-sults A total of 45 Hacmophilus par lainfluenzae were isolated from 760 specimen, with the isolation rate being 5.92%. Amoxicil-lin/claulanic acid,Azithromycin, Imipenem,Ceftazidime and Cefuroxime had the better antibiotic function and the average drug re-sistance was lower than 5 % ,The β-lactamase positive rate was 37.78 %. Conclusion The high drug resistance and β-lactamase pos-itive rate of Haemophilus par lainfluenzae isolated from respiratory tract characterized by multi-resistance must be taken seriousely.

Objective To investigate the differences in expression of hypoxia-inducible factor-1? (HIF-1?) in placental trophoblasts between normal pregnancy and pregnancy-induced hypertension (PIH) and the relationship of HIF-1? expression with magnesium sulfate treatment of PIH. Methods Immunohistochemical streptavidin biotin-peroxidase complex technique (SABC) was used to examine the expression of HIF-1? in 20 cases of PIH and 20 cases of normal placenta. Three groups of PIH were divided according to the degrees of severity. The results were analyzed by computer-assisted imaging and compared by t-test. Results There was significant difference in the expression of HIF-1? between the PIH group and the control group (P

Herbal drug-induced liver injury is a hot issue in the fi eld of TCM researches.Rapid screening and evaluating of herbal drug-induced liver injury have become one of the key techniques of herbal research.This text carried on the discussion on the research status of it from active,toxic ingredient,toxic mechanism and decreasing toxicity of Chinese herbal drugs.At the same time,the text viewed the application foreground of gene chip technique in the study of it.The current status and methods of it was discussed.In addition,most of the reports adopted in this paper were about studies on crude drugs,and discussion on how to correctly treat herbal drug-induced liver injury.

Objective To understand the serum adiponectin levels in normal subjects and type 2 diabetes patients with macrovascular complications, to investigate the correlation between adipnectin and macrovascular complications in type 2 diabetes patients. Methods One hundred and two normal subjects, 116 type 2 diabetes patients and 123 type 2 diabetic patients with macrovascular complications were recruited in the current study. The serum adiponectin levels among three groups were compared, and the factors affecting the serum adiponectin were investigated. Results ①The serum adiponectin level was significantly lower in type 2 diabetic patients (8. 62 ± 2. 97) mg/L than that in normal subjects (10. 03 ± 4.41) mg/L, and was the lowest in type 2 diabetic patients with macrovascular complications(6. 17 ± 2. 55) mg/L(P < 0.05). ②Serum adiponetin level was negatively correlated with BMI,WHR,HOMA-IR,fasting insulin level, HbAlC and TG(r = -0.492, -0. 581, -0. 813, -0. 754, -0.619, -0.387, P<0.05). ③In a general multivariate regression, HOMA-IR fasting insulin and HbAlc.were negatively correlated with serum adipnectin level (r = - 0. 828, - 0. 769, - 0. 631, P < 0. 01). Conclusions The serum adiponectin level in type 2 diabetic patients is significantly decreased and even more in type 2 diabetic patients with macrovascular complications. These results suggest that lower serum adiponectin level is related to macrovascular complications in type 2 diabetic patients and maybe plays an important role in atherosclerosis in type 2 diabetic patients.

Colorectal cancer is one of the most common malignancies with a high risk of liver metastasis in China. Compared with systemic chemotherapy, hepatic arterial infusion (HAI) transports cytotoxic agents directly into the hepatic artery, leading to the persistent level of medicine in tumor cells and the relative lower systemic concentration. With advances in HAI, this technique has been successfully used not only as the pre-and post-operative chemotherapy for the resection of colorectal liver metastases, but also as an ad-juvant chemotherapy after the colorectal radical surgery to prevent the liver metastasis. This review discusses the application and per-spective of HAI in the treatment of colorectal cancer liver metastasis.

The common respiratory pathogens which can cause children kidney disease include bacteria,viru-ses,mycoplasma pneumonia,and so on,the major clinical manifestations of infectious renal injury are glomerular nephri-tis,nephrotic syndrome,interstitial nephritis and renal subclinical glomerulonephritis. Group A β - hemolytic streptococ-cus is the most common cause of acute glomerulonephritis in children(50% - 90% ). Mycoplasma pneumoniae infec-tions and respiratory tract virus - associated renal injury are the important part of kidney disease in children with acute non - streptococcal infection,and comparing with the streptococcal glomerulonephritis,the process and prognosis of my-coplasma and virus infection are relatively better,and the level of blood urine,hypertension and serum complement is lower,with shorter duration and rapid recovery,and the duration of edema and proteinuria in children with nephrotic syndrome is shorter as well. There may be similar genetics and immunology pathogenesis between virus - induced wheezing or asthma and kidney injury in children.

Objective To investigate the effect of steroid hormones on lymphatic stomata of ovarian bursa and fluid adsorption. Methods The lymphatic adsorption was traced by trypan blue,and the ultrastructure of the lymphatic stomata and estrogen receptor level of mesothelial cells on ovarian bursa was observed by scanning electron microscopy,transmission electron microscopy and immuno-colloid golden technology. Results The absorption and opening area of lymphatic stomata were enhanced in estrogen group mice,and decreased in androgen group as compared to control group mice.Estrogen receptor was first identified in the nuclei of mesothelial cells on the inner layer of mice ovarian bursa and the level was down-regulated by estrogen and slightly up-regulated by androgen.Conclusion The absorption and the opening area of lymphatic stomata can be regulated by steroid hormones in mice,and the machanism may be related to the expression levels of estrogen receptor in the nuclei of mesothelial cells.
