OBJECTIVE: To explore the management pattern that conducive to the development of the Chinese Herbal Pieces Department.METHODS: The pros and cons of the comprehensive pharmacy management pattern for Chinese Herbal Pieces Department were analyzed.RESULTS: The introduction of the comprehensive pharmacy management pattern in the Chinese Herbal Pieces Department resulted in the reduction of the human,material and financial resources;however,it also led to declining of the quality of the cut crude drug,reduction in drug consumption,lowering of pharmacists' sense of responsibility,presence of more risk factors of dispensing errors,lowering of social concern,weakening of the position of Chinese medicine and marginalization of status of Chinese medicine.CONCLUSION: The inclusion of Chinese Herbal Pieces Department into comprehensive pharmacy management should be carried out with prudence or it might as well to maintain the relative independence of the Chinese Herbal Pieces Department so as to protect and develop the Chinese medicine.

Objective To evaluate experience for early diagnosis of pulmonary tembolism alter thoracic injury or surgery. Methods The 9 patients after thoracic injury or surgery with highly-suspected pulmonary embolism underwent chest radiograph of X-ray, helical CT pulmonary angiography, electrocardiogram, radionuclide pulmonary ventilation perfusion imaging, D dimer assay and arterial blood gas analysis respectively and the clinic data and results were analyzed. Results All patients were diagnosed and recovered after 8 patients received thrombolytic therapy and another patient received anticoagulant therapy. Conclusion If there were some symptoms such as suddenly severe dyspnea, cyanosis, with/without chest pains and the feeling of fear to death unable to be explained by original disease on those patients alter thoracic injury or surgery, it's very important for pulmonary embolism to be recognized, and early diagnosis and quickly efficient treatment is the key to prevent death. Helical CT pulmonary angiography is a safe, cheap, noninvasive and effective method for the diagnosis of pulmonary embolism with high sensitivity and specificity.

Objective To observe the effect of two reverse pedicle flap repaired soft tissue defect of the finger.Methods From April,2011 to March,2015,46 patients were randomly divided into two groups.Twenty-eight cases were performed by dorsal metacarpal artery flaps with cutaneous branches as pedicle and the 18 cases were performed by reverse the proper palmar digital artery dorsal branches island flap.The complication,survival rate,hand function and appearance were analyzed.Results The dorsal metacarpal artery flaps with cutaneous branches as pedicle and reverse the proper palmar digital artery dorsal branches island flap were an average follow-up of 18 and 15 months,all flaps survived.For fingertip defects,8 cases were repaired with as pedicle as the dorsal metacarpal artery flaps with cutaneous branches as pedicle while 16 cases were repaired with reverse the proper palmar digital artery dorsal branches island flap.Among them,complication included 2 cases of early venous congestion and 2 cases of superficial skin necrosis.One case of reverse the digital artery dorsal branches island flap blistered;the flap sensibility was good recovery.The two-point discrimination testing of dorsal metacarpal artery flaps with cutaneous branches as pedicle was from 6.0 to 9.0 mm (average of 7.1 ± 0.5 mm);the two-point discrimination testing of dorsal metacarpal artery flaps with cutaneous branches as pedicle was from 4.0 to 7.0 mm (average of 5.2 ± 0.4 mm),but there were differences in two-point discrimination and there was statistically significant (P ＜ 0.05).There was no significant difference between the two groups each finger interphalangeal joint activity compared with the healthy side.The study found that 10 cases of dorsal metacarpal artery flaps appearance was 5 mm higher than normal skin and 1 patient of reverse the digital artery dorsal branches island flap appearance was 5 mm higher than normal skin,the difference was statistically significant (P ＜ 0.05),the latter was better than the former,especially repaired fingertip defect.Conclusion Dorsal metacarpal artery flaps with cutaneous branches as pedicle and reverse the proper palmar digital artery dorsal branches island flap were safe and reliable,it is the ideal flap finger defects.For finger fingertip defect repaired reverse the proper palmar digital artery dorsal branches island flap is superior dorsal metacarpal artery flaps with cutaneous branches as pedicle.

Objective To analyze the antibiotic resistance of pathogenic bacteria recovered from bronchial secretions by bronchofiberscope in bronchiectasis patients complicated with infection for improving antibacterial therapy. Methods A total of 97 bronchiectasis patients complicated with infection treated in Liyuan Hospital during the period from June 2013 to December 2015 were included in this analysis. The pathogens were recovered from bronchial secretions by bronchofiberscope and subjected to antimicrobial susceptibility testing by Kirby-Bauer disc method. The data were analyzed with WHONET 5.5 software. Results Pathogenic organisms were isolated from 53 (54.6%) of the 97 patients, including 49 (92.4%) strains of gram negative bacilli, mainly Pseudomonas aeruginosa, followed by Acinetobacter baumannii, Klebsiella pneumoniae, 3 (5.7%) strains of?gram?positive?cocci,?specifically?2?strains?of?S. aureus and 1 strain of S. pneumoniae, and 1 (1.9%) strain of Candida albicans. Antimicrobial susceptibility testing showed that most P. aeruginosa isolates (>71.8%) were susceptible to tobramycin, amikacin,cefepime, and aztreonam, but 100% resistant to levofloxacin. More A. baumannii isolates were susceptible to tobramycin and amikacin (both 85.7%), followed by imipenem (>42.9%). More than half (>50%) of the K. pneumoniae isolates were resistant to cefotaxime, gentamycin, ciprofloxacin, and levofloxacin.Conclusions Gram negative bacilli are dominant in the pathogenic organisms recovered from bronchial secretions in bronchiectasis patients complicated with infection. Most of the pathogens are relatively susceptible to tobramycin and amikacin, but resistant to ciprofloxacin?and?levofloxacin.

Dihydroartemisinin (DHA),the major active metabolite of artemisinin,participates in tumor progression through the following ways:forming free radicals to induce cancer cells death dependent on iron,inducing apoptosis,inhibiting angiogenesis,tumor cells invasion and metastasis,modulating muhidrug resistance,controlling intracellular Ca2+ concentration,regulating cell cycles,cell autophagy and the immune system and so on.Generally,it is considered to be a potential anti-tumor drug.

[ ABSTRACT] AIM:To observe the effects of long-term cigarette smoke exposure on pulmonary vascular remode-ling and the protein expression of transforming growth factor-β1 ( TGF-β1 ) in the rats, and to explore the mechanism. METHODS:SD rats (n=36) were randomly divided into control group, 2-week smoke exposure (S-2W) group and 12-week smoke exposure (S-12W) groups.HE staining andα-smooth muscle actin staining were performed to observe the pul-monary vascular remodeling.The protein expression of proliferating cell nuclear antigen ( PCNA) and TGF-β1 in the pulmo-nary arteries was determined by the method of immunohistochemistry.The mRNA expression of TGF-β1 in the pulmonary arteries was evaluated by RT-qPCR.RESULTS:Compared with control group, ratio of pulmonary vessel wall thickness to vessel diameter ( WT%) and percentage of muscularized vessels were significantly increased in S-2W group and S-12W group ( P<0.01) .Significant increases in the protein expression of PCNA and TGF-β1 in smoke exposure groups were ob-served compared with control group.There was significant difference between 2 model groups (P<0.01).Compared with control group, the mRNA expression of TGF-β1 in pulmonary artery walls obviously increased in smoke exposure groups. There was significantly difference between S-2W and S-12W groups (P<0.05).The mRNA expression of TGF-β1 was positively correlated with pulmonary vascular muscularization, WT% and the protein expression of PCNA.CONCLU-SION:Long-term cigarette smoke exposure results in pulmonary artery remodeling in rats.The possible mechanism is that cigarette smoking exposure induces the over-expression of TGF-β1 at mRNA level in pulmonary vessels and promotes the proliferation of pulmonary vascular smooth muscle cells in rats.

Objective To analyze nucleophosmin (NPM1) gene mutations in exon 12 in patients with acute myeloid leukemia (AML) and evaluate the clinical appliance of three methods which are frequently used for detecting gene mutation. Methods Genomic DNA from bone marrow of 54 AML patients was detected by PCR for NPM1 exon 12 and screened by PCR-capillary electrophoresis, denature high-performance liquid chromatography (DHPLC) and direct sequencing separately. FLT3-ITD (FMS-like tyrosine kinease internal tandem duplication) was detected by agarose gel electrophoresis and PCR-capillary electrophoresis. Results Seven AML sample harbored NPM1 gene mutations. Five of them were the most common mutation, known as type A (an insertion of a TCTG tetranucleotide at position 960 bp). One of them was type D (an insertion of a CCTG tetranuclectide at position 960 bp). The new variant was a deletion of a TGGCAGTG sequence at 958 bp and insertion of a GCCCGCGGTTTA sequence instead. The detection ratio of the three methods was all 100% and capillary electrophoresis was more rapid, reliable and easier than the other two methods. Moreover it could detect FLT3-ITD simultaneously. The resolving power of DHPLC was affected by many factors. The direct sequencing method was tedious and the heterozygous sequence might be misread. Conclusions There is a new mutation at position 958 bp with a 12-nucleotide insertion and substitution. PCR-capillary electrophoresis is convenient to screen NPM1 mutations of AML in clinical practice.

ObjectiveTo understand the characteristics of mutations in BCR-ABL1 kinase domain mutation,these chronic myeloid leukemia (CML) and Ph positive acute lymphoblastic leukemia (ALL)patients who got imatinib treatment had poor effect.MethodsTotally 177 CML patients and 33 Ph( + )ALL patients were selected at Beijing Dao-Pei Hospital from Sep.2007 to Dec.2010.All of them were Chinese patients.Totally 243 bone marrow or peripheral blood specimens were collected from the patients,who had early effect,then resistance emergenced,or for more than 3 months of poor efficacy.Extracted total RNA from the specimens' nuclear cells,reversed transcription to cDNA.Amplified the whole span of BCRABL1 fusion kinase gene by nest PCR (from 242 to 493 amino acid coding sequence),used the type AB3130XL gene sequencing instrument determinate the gene sequence of ABL1 kinase region and then used the Variant Reporter V1.0 software to analyze the results of gene mutations.ResultsThirty-two kinds of different mutations were detected of ABL1 gene mutations,accounting for 34.2％ (83/243 cases).Among them,the T315I was 12％ (10/83),mutation rate was the highest,followed by Y253H was 11％ (9/83),G250E was 7％ (6/83),E255K was 7％ (6/83),M351T was 6％ (5/83),E459K was 5％ (4/83) ;Q252H,D276G,F317L,E355G,F359V,H396R were all 4％ (3/83).Three cases of insertion mutations were found,including 2 cases of 357-358insk,1 case of V304RfsX17.Seven patients had found existence two or more point mutations.The multiple drug resistance mutations might exist in the same leukemia clone.The same individual was not only contain common resistance mutations,but also rare point mutations,insertion mutations.The mutations might be lead to loss of kinase activity.ConclusionsUnder the imatinib drugs pressure,the ABL1 gene mutation in leukemia cells appears randomly,and results in different resistant clones.Different resistant clones can coexist in the same patients in vivo; resistant clones not only contain point mutations,but also contain inserted deletion mutations.

Objective To develop a multiplex sequence-specific PCR assay for simultaneous screening of 5 types of JAK2 mutations and investigate its clinical application value. Methods Multiplex sequence-specific PCR assay for simultaneous screening of JAK2 V617F, K539L (include 2 types of gene mutations), N542-E543del and E543-D544del mutations were developed. 115 patients with myeloproliferative diseases (MPD) including 61 polycythemia vera (PV) cases, 43 essential thrombocythemia (ET) cases and 11 primary myelofibrosis (MF) cases were analyzed. Results The assay can screen the 5 types of JAK2 mutations efficiently. The detection sensitivity is 1% for JAK2 V617F mutation and 0.1% for the other mutations. JAK2 V617F mutation and JAK2 exon12 mutation were detected in 56 and 3 of the 61 PV samples, respectively. 27 of the 43 ET samples and 6 of the 11 MF samples were JAK2 V617F positive, but no JAK2 exon12 mutation was found in both groups. The 3 cases carrying JAK2 exon12 mutation had the clinical feature of erythrocytosis and erythropoietin-independent erythroid colony formation but without apparent leukocytosis, thrombocytosis and splenectasis. Conclusion The assay can simultaneously screen 5 types of JAK2 mutations with high sensitivity and thus lead to an increased detection rate.
