Chinese Journal of Blood Transfusion 1988;0(01):-
Objective To study the clinical effectives of red blood cell transfusion in patients with chronic aplastic anemia (CAA). Methods 425 CAA patients, from January 1995 to August 2007, were reviewed, and the rate of ineffective transfusions and its relationship to patients' age, sex, level of Hb before transfusion, times and volume of previous transfusions were analyzed.Results Of the 425 patients, ineffective transfusions occurred in 39 patients (9.2%). Of the 1 416 units of red blood cells transfused, 249 units (17.6%) were ineffective. The ineffective transfusions were not related to patients' age, sex or levels of Hb before transfusion, but were related to the times and volume of previous transfusions.Condusion In CAA patients, the more the times and the larger the volume of previous transfusions, the higher the rate of ineffective transfusion would occur.

OBJECTIVE:To study relative bioavailability of dauricine self-microemulsifying drug delivery system (SMEDDS) in rats. METHODS:12 rats were randomly divided into dauricine SMEDDS group (20 mg/kg) and dauricine solution group (50 mg/kg),6 rats in each group. They were given relevant medicine intragastrically. Then,0.3 ml plasma was collected from orbital venous plexus before medication and 0.167,0.333,0.5,0.75,1,2,4,8,12,24,36 h after medication. The plasma concentration of da- uricine was determined by HPLC-MS/MS,and DAS 3.0 was used to calculate pharmacokinetic parameters and evaluate the relative bioavailability of dauricine with dauricine SMEDDS. RESULTS:The linear range of dauricine in plasma were 2.12-424 ng/ml (r=0.999 9);RSDs of intra-day and inter-day were all lower than 10%. Pharmacokinetic parameters of dauricine solution and dau-ricine SMEDDS were that cmax were(126.3±37.4)ng/ml and(179.6±51.5)ng/ml;t1/2 were(11.48±4.58)and(21.79±6.59)h;AUC0-t were (1 963.5±638.3)ng·h/ml and(2 535.8±739.5)ng·h/ml;AUC0-∞ were(2 256.3±703.5)ng·h/ml and(2 854.6± 768.7)ng·h/ml,respectively. The relative bioavailability of dauricine SMEDDS were 323% and 316% by calculating with AUC0-t and AUC0-∞,respectively. CONCLUSIONS:Intragastric administration of dauricine SMEDDS can improve relative bioavailability of dauricine significantly.

Objective To explore the effect of medicated serum of Sangleng and Eshu on the expression of vascular endothelial growth factor and vascular endothelial cell proliferation induced by VEGF in vitro. Methods Medicated serum of Sangleng and Eshu was used to culture human umbilical vein endothelial cell (HUVEC-1) induced by VEGF. The morphologic changes of HUVEC-1 were observed with phase contrast microscope, and cell proliferation was detected by MTT method, and the expression of vascular endothelial growth factor protein and mRNA in endothelial cells was detected by Western blotting and RT-PCR. Results The medicated serum of 5.0, 2.5 g?kg~ -1 ?d~ -1 Sangleng and Eshu could cause arrangement disorder in the normal umbilical vein endothelial cells. The medicated serum of 5.0 g?kg~ -1 ?d~ -1 Sangleng and Eshu (10%, 5%, 2.5%) and medicated serum of 2.5 g?kg~ -1 ?d~ -1 (10%) could inhibit vascular endothelial cell proliferation remarkably (P

OBJECTIVE:To improve the synthesis technology of sorafenib tosylate (Ⅰ). METHODS:The intermediate N-methyl-(4-chlorpyridin-2-yl)carboxamide(Ⅳ)was obtained by chlorination and amidation with 2-picolinic acid as the starting com-pound. Meanwhile,N-[4-chloro-3-(triflouromethyl)phenyl]-N′-(4-hydroxyphenyl)urea (Ⅶ) was prepared from aminophenol and 4-chloro-3-trifluoromethyl phenyl isocyanate,which was obtained from 4-chloro-3-(trifluoromethyl)aniline(Ⅴ)by reaction with initiator triethylamine. Sorafenib tosylate was synthesized from Ⅳ and Ⅶ with potassium tert-butoxide by condensation and salt for-mation. The target compound was characterized by 1H-NMR. RESULTS:The target compound was confirmed as Ⅰ,with the over-all yield of 74% [based on 4-chloro-3-(trifluoromethylanilin)]. The purification of chromatogram was 94%. Optimized technology improves yield and simplifies multi-step intermediate decompression,distillation and purification process;the application of initia-tor shortens the duration of reaction. CONCLUSIONS:Ⅰ is prepared successfully,and raw material can be obtained easily and is easy to operate with high yield.

AIM: To establish nasopharyngeal carcinoma(NPC) cell lines stable expressing NPC-derived latent membrane protein 1(LMP1) gene. METHODS: General expression vector and epithelium-specific expression vector of NPC-derived LMP1 gene were constructed by using recombinant techniques, then transfected these vectors into a poor differentiated NPC cell line named CNE-2 ,integration and expression of N-LMP1 in CNE-2 cells were detected by PCR,RT-PCR and Western blot. RESULTS: (1) General expression vector and epithelium-specific expression vector of NPC-derived LMP1 gene were constructed successfully.(2) It showed that N-LMP1 gene expressed in CNE-2 cells correctly. CONCLUSION: The first NPC cell lines which stable express NPC-LMP1 were established. The cell lines obtained will provide important basis for exploring the role of NPC-LMP1 in nasopharynx carcinogenesis.

Objective To investigate the effect of quality control circle on reducing incidence of fecal incontinence dermatitis of intensive care unit (ICU) patients. Methods Quality control circle team was set up and theme was determined then retrospective analysis was carried out for the occurrence of defect in patients with fecal incontinence dermatitis from January to May 2014 before quality control circle activities. Occurrence reasons were explored and corrective measures were formulated and implemented.After the implementation of quality control circle,the occurrence of defect from June to October 2014 was observed. Results After the implementation of quality control circle,the occurrence of fecal incontinence dermatitis reduced from 24.5%(24/98) to 10.4% (10/96) and the difference was statistically significant,χ2=6.65, P<0.05. Conclusion Quality control circle is effective for reducing the occurrence of ICU fecal incontinence dermatitis and continual improvement of nursing quality.
