5R-5-hydroxytriptolide (LLDT-8) is a new drug candidate which is in clinical trial treating rheumatoid arthritis. Polymorph screening of the compound was carried out in this study. Polymorph of LLDT-8 was prepared by evaporative crystallization and antisolvent crystallization methods and was characterized by powder X-ray diffraction (p-XRD), infrared spectrometry (IR), differential scanning calorimetry (DSC) and thermogravimetric analysis (TG). It was found that p-XRD patterns, DSC curves, TG curves and IR spectra of the LLDT-8 samples prepared by the above recrystallization methods were all consistent. The 20 of main peaks in the p-XRD patterns appeared at 7.58 degrees, 8.14 degrees, 8.66 degrees, 15.46 degrees, 16.46 degrees, 29.54 degrees, 31.16 degrees and 38.26 degrees, while the infrared absorption peaks appeared at 3 471.3, 2 962.2, 2 887.0, 1 762.6, 1 677.8, 1 432.9, 1 365.4, 1 247.7, 1 080.0, 1 031.7 and 877.5 cm(-1). LLDT-8 was decomposed at 271.2 degrees C based on the determination from DSC and TG. It was showed in single crystal X-ray diffraction study that LLDT-8 crystal was monoclinic with the space group being P2 (1). The cell parameters were found to be: a = 11.460 1 (11), b = 6.320 5 (6), c = 13.028 1 (12), alpha = 90.00, beta = 115.557 (2) and gamma = 90.00. The crystal was a hydrogen-bonded dimmer. The slurry experiments, which were further conducted in solvents with different polarities, confirmed the stability of solid state of LLDT-8 based on the p-XRD determination. The polymorph of LLDT-8 made assurance of its efficacy consistence during its clinical trials.

Objective To investigate the protective role of Jidesheng Sheyao tablet in lipopolysaccharide (LPS)-induced acute lung injury(ALI) in rats. Methods Fifty male SD rats were randomly divided into 6 groups:normal control group,dexamethasone positive group,LPS model group, Sheyao groups of low, middle and high dosages successively.All rats, except normal control group, were administrated with LPS by intravenous injection to induce acute lung injury. The rats in positive group and three different dosage groups were treated by dexamethasone(3 mg?kg -1, iv), low dosage(0.8 g?kg -1), middle dosage(1.6 g?kg -1) and high dosage(3.2 g?kg -1) of Jidesheng Sheyao tablet(oral) respectively before LPS-induced ALI. Each rat in normal control group received injection of 1ml normal saline. The animals were killed after injection of LPS for 2 hours, and then the lung index was calculated, the histopathology of the lung injury was observed by light microscope, the expression of matrix metalloproteinase-2 (MMP-2), matrix metalloproteinase-9 (MMP-9) proteins in the lung tissues and their activity in the bronchoalveolar lavage fluid (BALF) and the lung homogenates were detected by immunohistochemistry and zymography separately. Results Compared with model group, the lung indexes were significantly decreased in the drug groups(P

OBJECTIVETo observe the effective mechanism and side effects of thalidomide to multiple myeloma (MM).
METHODSTen cases of MM were studied, of which 3 were previously untreated and 7 refractory or relapsed. Bone marrow microvascular density (MVD) was detected by factor-VIII related antigen and CD(34) immunohistological staining and serum concentration of vascular endothelial growth factor (VEGF) before and after treatment was determined by ELISA. The initial dosage of thalidomide was 100 approximately 200 mg/d with a weekly escalation of 50 mg/d to 450 approximately 650 mg/d. The therapeutic effectiveness is classified into partial remission, improvement and uneffective according to the decrease of serum M protein and bone marrow myeloma cells. Anemia, renal function and blood electrolytes were also observed.
RESULTSBefore treatment, MVD was 73.32 +/- 28.80 and 32.30 +/- 12.50 in MM and control group, respectively, (P < 0.01). MVD in MM group decreased to 56.12 +/- 19.34 after treatment, and was of significant difference (P < 0.05) as compared to the pretreatment value. However, there was still a significant difference as compared to control (56.12 +/- 19.34 vs 32.30 +/- 12.50, P < 0.01). The concentration of VEGF significantly decreased after treatment [from (178.23 +/- 26.56) ng/L to (78.48 +/- 19.98) ng/L, P < 0.01)]. The total effective rate was 70%. There were no serious side effects.
CONCLUSIONMVD and VEGF concentration were decreased obviously by thalidomide treatment. The dosage of 450 approximately 650 mg/d might be effective in refractory or initial MM.

OBJECTIVETo investigate the blood test patterns for blood donors after nucleic acid detection in blood center.
METHODSThe collected blood samples after voluntary blood donors first were detected by conventional ELISA, then 31981 negative samples were detected via HBV/HCV/HIV combined nucleic acid test of 6 mixed samples(22716 cases) or single samples(9265 cases) by means of Roche cobas s201 instrument. The combined detection method as follows: the blood samples were assayed by conventional nucleic acid test of 6 mixed samples, at same time, 6 mixed samples were treated with polyethylene glycol precipitation method to concentrate the virus, then the nucleic acid test of blood samples was performed; the single detection method as follows: firstly the conventional nucleic acid test of single sample was performed, then the positive reactive samples after re-examination were 6-fold diluted to simulate the nucleic acid test of 6-mixed samples. The positive rate of positive samples detected by combined nucleic acid test, positive samples detected by nucleic acid test of mixed virus concentration and positive samples detected by single nucleic acid test was statistically analyzed. In addition, for HBVpersons the serological test yet should be performed.
RESULTSIn 22 716 samples detected by nucleic acid test of 6 mixed samples (MP-6-NAT) , 9 cases were HBV(0.40‰, 9/22716); at same time, the detection of same samples by nucleic acid test of mixed sample virus concentration showed 29 cases of HBV(1.28‰, 29/22716). In 9265 samples detected by single nucleic acid test(ID-NAT) 12 cases showed HBV(1.30‰, 12/9265), meanwhile the detection of these 12 samples with HBVby 6-fold dilution for virus concentration found only 4 samples with HBV. In serological qualified samples, ID-NAT unqualified rate was 1.28‰, which was higher than that of MP-6-NAT(0.4‰) (χ=8.11, P<0.05); but there was no statistical difference between unqualified rate of ID-NAT and MP-6-NAT(1.3‰ vs 1.28‰)(χ=0.00, P>0.05). In 41 samples with HBsAgHBV DNAdetected by ELISA, 36 samples were confirmed to be occult HBV infective(OBI) by HBsAb, HBcAb test of ELISA; out of these 41 samples, 33 samples showed HBcAb(91.66% of OBI), 5 might be HBV "window period" infective, moreover the HCV RNA and HIV RNA positive samples were not found.
CONCLUSIONTo avoid the missdiagnosis of donors with low level of virus, the nucleic acid test must be carried out after virus concentration of mixed samples when the blood test pattern of donors is nucleic acid test of mixed samples, otherwise the single nucleic acid test must be performed to obtain more high detected rate of virus nucleic acid. The HBcAb serologic test and physical examination of donors before blood donation must be enhanced on basis of serological test of HBsAg; for high risk people, the persuading no blood donation is simplest pattern.
