ObjectiveTo investigate the relationship between hepatitis B markers and HBV-DNA content.Methods230 cases with hepatitis were selected.ELISA method was used to detect serum markers,PCR method fordetecting the content of HBV-DNA.ResultsIn 76cases of HBeAg positive specimens,72 cases were HBV-DNA positive,the positive rate was 94.7％ ; in 154 patients with HBeAg negative specimens,72 cases were HBV-DNA posifive,the positive rate was 46.7％.The difference between HBeAg positive group and HBeAg negative group was statistically different( P ＜0.01 ).ConclusionIn patients with chronic hepatitis B,serum markers reflected,HBV can understand the in vivo infection,cannot directly reflect the in vivo replication of HBV.Detection of HBV-DNA content can better reflect the virus replication.

This study was aimed to obtain a general knowledge of physical status and its chronological changes in young Chinese recruits. 73 000 physical examination data of young male recruits were collected in 100 sample units selected by the method of cluster sampling from 31 provinces in China. Height, weight, chest circumference, and body mass index(BMI) were analyzed. The results showed that the recruits from Northeast China and North China were the tallest (170 3cm and 170 6cm on average), the heaviest (60 4kg and 61 6kg), their chest circumference largest(83 4cm and 84 6cm), and their BMI were the largest(20 8 and 21 5kg/m 2). Comparing with historical data, the average height increased 6 6cm since 1955 and 4 1cm since 1974. The body weight increased 5 6kg since 1955 and 3 5kg since 1974. Chest circumference increased slightly, the mean values of which in the three periods were 20 3, 20 1 and 19 8kg/m 2, respectively. The recruits from southwertern and south China showed least growth, and their BMI was virtually lower than before. The results of this survey indicated that a significant difference in the physical status among youth recruits from different areas in China. Lack of growth of chest circumference and BMI in youths from some areas should arouse our attention

Objective To analyze the consistency of individual examination diagnosis with terminologies expressed in the conclusion report of physical examinations by the chief inspection physician. Methods Based on the clinical classifications used in the Guidelines on Prevention and Treatment of Blood Lipid Abnormality for Chinese Adults, and related terminology descriptions of Dyslipidemias that were actually used in four-item blood lipid examinations diagnosis, a lexicon database of Hyperlipidemias was constructed with 39 terms used in the four-item blood lipid examination diagnosis and chief physician conclusions. Totally 11953 electronic chief physician inspection reports from 8 health check-up institutions were included. We investigated the terms of lexicon database using word frequency analysis method, calculated the positive rate in the diagnosis of four single examinations of serum lipid and the positive rate in the chief physician's conclusion. Consistency of chief physician's conclusion with single examination diagnosis was analyzed by Kappa test. Results (1) Among the 39 terms of lexicon database, there are 18 nonstandard terms used in single examination diagnosis, accounted for 46％ of all terms; (2) In word frequency analysis, there are only 1％ of terms that corresponded to clinical classifications of Hyperlipidemias accurately;(3) The positive rate of Hyperlipidemias in serum lipid four single examinations diagnosis was 47％, the positive rate of physician diagnosis was 35％. The consistency analysis of chief physician conclusions with single examination diagnosis showed Kappa=0.71(P<0.01). Conclusions Although the final conclusion written by the chief physician was not using standard terms strictly, most of synonymous terminology expressed in the physician conclusion is normative, which enabled the construction of lexicon database and text mining. Whether the single examination diagnosis are consistent with physician conclusions can be an evaluation indicator to assess the quality of chief physician conclusions for physical examinations. Kappa>0.75 may be suggested as a favorable value.
