Purpose:To evaluate the effects of the implementation of “Guidelines of Diagnosis and Treatment for Common Cancers in China (Breast cancer)” in recent 10 years, and to provide evidence for decision making for Health Services.Methods:Continuously followed and randomly sampled hospitalized breast cancer cases in District hospitals and General hospitals, evaluated by clinical experts.Results:The rate of total agreement was 41.36%, the rate of essential agreement was 49.09% in 1996-1999. The sum of the two rates was 90.45%. The total agreement rates were without statistical difference among district hospitals, county hospitals and municipal general hospitals. There was no case of disagreement in municipal general hospitals. The disagreement rate in district hospitals went down from 7.69% in 1994 to 3.70% in 1999. The total agreement rate of cases with operation was 46.74%, higher than any group with other treatments. The proportion of cases with correct case stage classification was 47.33%.Conclusions:After implementation of the Guideline, the level of appropriate treatment was increasing. In order to raise the level of cancer diagnosis and treatment, and improve cure rate, survival rate and life quality, we must take measures on staff training, quality control, supportive environment, comprehensive patient management and patient transfer policies.[

Spermiogenesis is a complex process of differentiation and morphologic alteration, in which sperm acrosome formation is an important stage. Acrosome is an essential component of the sperm head, which develops in four distinct phases: Golgi, cap, acro- somal, and maturation, each supported by precise and orderly regulation of various genes. The regulatory genes which act on Golgi ap- paratus include GOPC, Hrb, SPATA16, PICK1, and CK2α', those involved in the cap phase are Fads2, syntaxin 2, Kdm3a, and UBR7, and participating in acrosomal and maturation phases are KIFC1, Rnf19a, and DPY19L2. The abnormalities of these genes may affect male fertility by influencing the connection of the nuclear dense lamina and acroplaxome with the nuclear membrane and then the fusion and transportation of vesicles. This review focuses on the genes involved in different phases of acrosome formation.

OBJECTIVETo estimate the coverage level of case reporting for coal workers' pneumoconiosis (CWP) and the incidence of CWP in China according to the data from CWP reporting database in China as well as the data on annual raw coal output, coal workers, etc. from relevant year books, and to provide scientific data for CWP control measures.
METHODSThe data on the numbers of coal workers and annual raw coal outputs of national top 100 enterprises in coal sector (Top 100 in coal sector) were acquired from China Coal Industry Yearbook; the annual per capita output of raw coal in each enterprise was calculated. The numbers of coal workers in the enterprises other than the Top 100 were estimated based on the annual per capita output of raw coal in the Top 100 and the annual raw coal outputs of the enterprises other than the Top 100. The numbers of coal workers in the enterprises that reported CWP cases were estimated based on the distribution of these enterprises in China, and the coverage rates of case reporting in the Top 100 and other enterprises were calculated accordingly. The total number of CWP cases and the number of CWP cases due to per million tons of raw coal output were estimated according to the coverage rates of case reporting and the total numbers of reported CWP cases in China.
RESULTSThe mean coverage rates of case reporting in the Top 100 and other enterprises were 55.34% and 5.18%, respectively. The estimated mean numbers of new CWP cases in the Top 100 and other enterprises were 3088 and 98205, respectively; the estimated total number of new CWP cases nationwide was 101293. The estimated mean numbers of new CWP cases due to per million tons of raw coal output were 2.05 in the Top 100 and 7341 in other enterprises. The number of reported CWP cases accounted for 6.7% of the estimated number of CWP cases (6796/101293).
CONCLUSIONIt is urgent to enhance occupational disease control in coal sector, and the estimation results for CWP should be spread and applied. The system of occupational disease control should be further improved.

Objective To build an antibody microarray based on direct labeling strategy for microalbnrninuria measurement, and evaluate it's technical potentiality for clinical application. Methods Urine samples of diabetic patients were collected. Antibody microarrays were constructed by preparation of array support, array fabrication, then protein assay and data analysis were performed. Procedure conditions for each step especially the labeling of samples were optimized. The set-ups were evaluated in terms of sensitivity, specificity and reproducibility. Urinary albumin excretion in the samples was detected by fabricated protein array, which was compared to that detected with immunoturbidimetry. Results The signal intensity was best when protein quality ratio of pure albumin or urine sample against NHS-biotin was 2:1. A calibration curve with a correlation coefficient of 0.9995 was established. The lower limit of detection was 0.0617 mg/L. Interehip and intrachip variation studies conducted on patient urine demonstrated CVs as 6.78%-9.22% and 3.35%-7.59%, respectively. Compared with the immunoturbidimetry, the antibody microarray was able to detect the extremely lower grade albumin in urine samples. The correlation coefficient of the results obtained by the two methods was 0.9199 (P <0.01). Conclusion An antibody microarray based on direct labeling strategy for microalbuminuria measurement is successfully established, which is comparable to immunoturbidimctry in its accuracy and will have great potential for clinical use with its high throughput, sensitivity, specifity and reproducibility.
