Objective To compare the results of three methods for measuring C reaction protein.Methods 100 patients were collected from our hospital,and three different methods for measuring C reaction protein were used to analyze the level of C reaction protein.Results Correlation analysis showed that the correlation between immunoturbidimetric assay and immunochromatography was higher.The differences of three methods assayed the C reaction protein were significant (P <0.05 )among normal people by the variance analysis,but had not statistical significance among abnormal people (P >0.05).The differences among all of test peo-ple were significant(P <0.05).Conclusion Detection of C reaction protein was important for diagnose inflammatory diseases.

Objective To explore clinical characteristics of Chinese patients with lupus erythematosus (LE).Methods Data were obtained from the Lupus Erythematosus Multicenter Case-control Study in Chinese populations (LEMCSC).A unified standard was used to recruit patients and collect clinical information.The EpiData 3.1 and SPSS 18 softwares were utilized to input and analyze data respectively.Results One thousand and six patients (87.6％ female) with lupus erythematosus (LE) were included in this analysis,of whom,887 (89.9％ female) had systemic LE (SLE),and 119 (70.6％ female) had isolated cutaneous LE (CLE).The most common involved system in SLE patients was skin (72.7％),followed by joints (69.2％),hematological system (60.8％),kidney (48.5％),serosa (18.2％),and nervous system (5.7％).The appearance of LE-specific skin manifestations was associated with an increased risk of arthritis (odds ratio [OR] =1.612,95％ confidence interval [CI]:1.181-2.200),but with a decreased risk of nephritis (OR =0.218,95％ CI:0.157-0.303) and serositis (OR =0.311,95％ CI:0.218-0.443).The presence of acute CLE (ACLE) lesions was a risk factor for systemic involvement (OR =4.931,95％ CI:3.232-7.524),while that of chronic CLE (CCLE) lesions was a protective factor for systemic involvement (OR =0.355,95％ CI:0.234-0.541).The appearance of LE-nonspecific skin manifestations was closely correlated with the involvement of internal organs in patients with LE.Conclusion This study revealed main characteristics of LE patients in China and the relationship between LE-related skin lesions and internal organ involvement.

ObjectiveTo investigate the effects of different therapeutic methods on borderline hypertension with metabolic syndrome patients. MethodsNinety borderline hypertension with metabolic syndrome patients were divided into three groups by random digits table with 30 cases: control group,conventional therapy group and intensive therapy group. The control group was given regular observation, the conventional therapy group took drug according to the disease situation; and the intensive therapy group not only formulated the aim of therapy, but also received diet control, sport therapy, healthy education and drug therapy. After 1 year's follow-up, the patients' changes were compared. ResultsAfter 1 year's follow-up,the levels of FPG, 2 h PG, 24 h mAlb and IMT were significantly increased(P ＜ 0.05 ), and the levels of other index had no significant changes (P＞ 0.05) in control group. The levels of FPG,2 h PG,TC and TG were significantly decreased and IMT was significantly increased(P ＜0.05), the levels of other index had no significant changes(P ＞ 0.05 ) in conventional therapy group. The levels of SBP, DBP, PP, FPG, 2 h PG, TC,TG,hs-CRP,24 h mAlb and HOMA-IR were significantly decreased and HDL-C, ABI were significantly increased (P ＜ 0.01 or ＜ 0.05 ) in intensive therapy group. After treatment, the levels of ABI and H DL-C were significantly higher and SBP, DBP, PP,TG, hs-CRP, 24 h mAlb, HOMA-IR, IMT were significantly lower in intensive therapy group than those in conventional therapy group (P ＜ 0.01 or ＜ 0.05 ). ConclusionsDrug therapy is efficient in borderline hypertension with metabolic syndrome patients, and intensive therapy can obviously improve the insulin resistance, to control the developing of hypertension can delay the vascular

To establish induction and liquid culture system for hairy roots of Danshen (Salvia miltiorrhiza), Agrobacterium rhizogenes A4, LBA9402, 15834 as test bacterium were used to infect aseptic leaves of Danshen. The hairy roots were induced and positive transgenic hairy roots were selected with PCR using rolB and rolC as the target gene. Then hairy roots of S. miltiorrhiza were harvested and salvianolic acids were extracted with 70% methanol containing 1% formic acid. The content of salvianolic acid B (SalB) and rosmarinic acid (RA) were determined by HPLC. According to the above research results, the Danshen hairy roots induced by A. rhizogenes LBA9402 were inoculated into the following group of culture media: MSOH, MS, B5, and 6,7-V liquid media. Then the same methods of extraction and determination for the content of Danshen hairy roots were adopted. Last, the hairy roots of S. miltiorrhiza induced by A. rhizogenes LBA9402 were inoculated into the MSOH liquid media with different pH values. The content of salvianolic acid were extracted with 70% methanol containing 1% formic acid and determined by HPLC. As a result, three kinds of A. rhizogenes A4, LBA9402, 15834 could induce hairy roots and Ri plasmids were integrated into the genome of S. miltiorrhiza by PCR. Danshen hairy roots induced by A. rhizogenes LBA9402 and A4 produced much more salvianolic acid, which were (3.27 ± 0.37)% [including (1.04 ±0.36)% of RA and (2.22 ± 0.29)% of SalB] and (3.17 ± 0.20)% [including (0.92 ± 0.31)% of RA and (2.25 ± 0.26)% of SalB], respectively. Hairy roots induced by A. rhizogenes LBA9402 when they were cultured in MSOH liquid media produced much more salvianolic acid, which was (4.56 ± 0.36)%, including (1.12 ± 0.26)% of RA and (3.44 ± 0.23)% of SalB. Hairy roots induced by A. rhizogenes LBA9402 produced the most salvianolic acid when they were cultured in MSOH liquid media with the pH value 4.81, which was 4.85%, including 1.16% of RA and 3.69% of SalB. So Danshen hairy roots induced by A. rhizogenes LBA9402 and A4 produced much more salvianolic acid when they were cultured in MSOH liquid media with the pH value 4.81. The research had established the foundation on genetic engineering to improve the quality of S. miltiorrhiza.
