Objective To analyze HRCT and thin-slice CT scan findings in 150 patients with pulmonary diffuse mild micronodule, and to find the features with the purpose of identifying random micronodule, peri-lymphatic micronodule, and centrilobular micronodule. Methods The useful features in 150 patients with pulmonary diffuse mild micronodule were translated into scores by means of discrimination method of large log-likelihood to identify the micronodular category. Results The accuracy of diagnosis was 94.0% for random micronodule, 76.0% for peri-lymphatic micronodule, and 90.0% for centrilobular micronodule. Conclusion HRCT and thin-slice CT scans were helpful in differential diagnosis of pulmonary diffuse mild micronodule. The discrimination method of large log-likelihood was propitious to diagnosis and differential diagnosis.

OBJECTIVE:To determine the plasma concentration of mycophenolic acid (MPA) in renal transplantation patients by HPLC-Fluoremetry. METHODS: The sample was subjected to precipitation of proteins using 5% Zinc Sulfate methanol saturated solution,and the supernatant (20 ?L) was taken for sample injection and determination on Zorbax Eclipse XDB C18 with mobile phase consisted of acetonitrile-methanol-0.2 mol?L-1 glycine buffer(18∶2∶80,pH=9.0) at a flow rate of 1.0 mL?min-1. The column temperature was of 25℃;the excitation wavelength(EX) was 342 nm and the emission wavelength(EM) was 425 nm. RESULTS: The linear range of MPA was 0.5~40 mg?L-1,with its lowest limit of quantitation at 0.5 mg?L-1. The methodology recovery was 98.23%~101.00%;the extraction recovery of MPA was 91.56%~94.46%;the intra-day RSD was 0.64%~3.22% and the inter-day RSD was 5.12%~6.10%. CONCLUSION: The method is sensitive,rapid,accurate,convenient,and applicable for the quantitative determination of plasma concentration of MPA in renal transplantation patients.

Chronic obstructive pulmonary disease (COPD) with high morbidity and mortality has become a major public health problem.Health education can improve the quality of life in patients with COPD, and reduce the number of exacerbations and cost due to repeated hospitalizations. There is no unified conclusion in content, manner, time for health education. There are large number of patients with COPD in China. Patients are generally poorly aware of the disease, and need various content and form of education, which can't meet for lack of knowledge and less focus on health education of medical workers. Many new progresses are emerging, such as the commonwealth of education, integrity and improvement of education, and enhancement of the educators.

Objective To observe vasculogenic mimicry (VM) of human choroidal melanoma cell line OCM-1 cultured in vitro and the expression of PI3K and EphA2 protein,as well as to explore the possible mechanisms.Methods OCM-1 cells were cultured in vitro and stained with periodic acid Schiff (PAS) on days 7,which aimed to observe the formation of PAS-positive cyclic structures,that is,VM formation.Then immunohistochemical staining was performed to detect PI3K and EphA2 on day 1,4,7 and the results were observed.Ressults On day 4 of 3-demintional culture,most of OCM-1 cells were polygonal and the cytoplasm was abundant;the nuclei were round and the nucleoli were visible.A small part of the tumor cells were long spindle.It was found that several long spindle cells were connected to each other to form hemicyclic structure.After 7 days,a large number of tumor cells became long spindle,growing along the collagen scaffold,and long protrusions appeared,forming a ring structure.PAS staining showed that the tumor cells were mostly arranged in a row,and tumor cells imitated the formation of body blood vessels,resulting in cell band and pipeline-like cell layers,with one layer of extracellular matrix (PAS-positive substance) making up the ring structure.Moreover,the expression levels of PI3K and EphA2 on day 4 and 7 were significantly higher than those on day 1 (all P < 0.05),and their expression levels on day 7 were higher than those on day 4 (all P < 0.05).Conclusion EphA2 and PI3K may play an important role in the VM formation in 3-dimentional culture of human choroidal melanoma cell line OCM-1.

OBJECTIVE:To prevent and reduce the occurrence of nosocomial deep mycosis.METHODS:The medical records of patients with nosocomial deep mycosis in the period from January2001to December2002in this hospital were ret?rospectively analysed.RESULTS:There were43patients with nosocomial deep mycosis,which accounted for10.54%of all nosocomial infections in the same period.The predilection sites were respiratory tract(34.88%)and digestive tract(30.23%). The main pathogen was Candida albicans(77.78%).All patients had serious underlying diseases and were treated with broad-spectrum antibiotics,and some of them had received adrenocortical steroids.CONCLUSION:Rational use of broad-spectrum antibiotics and adrenocortical steroids is the most important way to prevent deep mycosis and improve the prognosis.

Objective To observe the effect of BSD 2000 deep thermotherapy plus chemotherapy in treatment of malignant seroperitoneum of advanced epithelial ovarian cancer patients with drug resistance.Methods 36 advanced epithelial ovarian cancer patients with malignant seroperitoneum for drug resistance were randomly divided into two groups,trial group (18 cases) and control group (18 cases).Cases in trial group were treated with BSD 2000 deep thermotherapy plus GT regimen (gemcitabine 1 000 mg/m2 iv d1,d8,taxinol 80 mg/m2 ip d1,d8.28 days for a cycle),while control group with GT regimen alone.Effect,survival time (median) toxicity and Karnofsky score were evaluated after 2 cycles.Results Response rate (RR) was strongly higher in trial group compared with control group [55.6 % (10/18) vs 22.2 % (4/18),P < 0.05],the same to disease control rate (DCR),but there was not significant difference between two groups (P > 0.05).The improvement rate of Karnofsky score in trial group was higher than that in control group,which had no significance (P > 0.05).The toxicity were similar in both groups,which had no stage 3 to 4 side-effect.The differences of survival time (median) and survival rate had no statistical significance between two groups (P > 0.05).Conclusion It is useful to eliminate seroperitoneum,improve quality of life and decrease the toxicity for the regimen of BSD 2000 deep thermotherapy plus chemotherapy in treatment of malignant seroperitoneum of advanced epithelial ovarian cancer patients with drug resistance.

Objective To discuss the relation between gynecologic tumor and dysmenorrheal and tongue petechia, make clear the diagnostic value of tongue petechia in gynecology department tumor and dysmenorrheal, and provide theoretic basis for diagnosing gynecologic diseases by TCM. Methods A total of 169 patients with gynecologic tumor and dysmenorrheal were set as a treatment group, and a total of 211 patients who excluded the tongue signs of gynecologic tumor and dysmenorrheal were set as a control group. Tongue petechias were identified and compared between the two groups. Results ①Probability of tongue petechia showed a significantly higher value in the treatment group than the control group. (P<0.01) ; ②Probability of tongue petechia showed a significantly higher value of patients with tumor in the treatment group than patients with other gynecologic diseases in the control group (P< 0.05) ; ③Probability of tongue petechia showed a significantly higher value of patients with dysmenorrhea in the treatment group than patients with other gynecologic diseases in the control group (P<0.01). Conclusion ①Relevant researche of gynecologic tumor, dysmenorrheal and tongue petechia at the tip of tongue was based on TCM theory, diagnostics and clinical experiences. The data of this study has proven this diagnostic method.②Compared with other kinds of diseases, gynecologic tumor and dysmenorrheal showed a higher probability in the appearance of tongue petechia. Therefore, petechia at the tip of tongue can be used as one of diagnostic references for gynecologic tumor and dysmenorrheal.
