Chronic myeloid leukemia is a kind of malignant cloning hyperplastic disease of hematopoietic stem cell .The treatments based on molecular biological and immunological techniques will become the new therapies .Gene silence can improve the effects of molecular targeted therapeutic drugs through two ways: one is the target mRNA can be digested by siRNA and the other is target gene lose the stability and reduce the generation of protein mediated by miRNA .Adoptive cel-lular immunotherapy is a treatment method through injecting immunocompetent cells such as CIK , NK, etc into the body of cancerous person .This can improve the immunity of body and the effects of molecular targeted therapeutic drugs .The fur-ther study about basic theory , molecular mechanism and clinical effects will be continued .

To investigate the chemical constituents of the roots of Aconitum taipaicum, silica gel column chromatography was used for the isolation and purification of compounds. A new norditerpenoid alkaloid, isodelelatine (1), along with five known alkaloids, atisine (2), delfissinol (3), liangshanine(4), hypaconitine (5) and delelatine (6) were isolated and identified. The structure of the new compound was elucidated on the basis of spectral data.

OBJECTIVE:To explore the teaching model and method of pharmacy case analysis writing in standardized clinical pharmacist training. METHODS:Based on the training experience in our hospital,the purpose,contents,common problems and summary of pharmacy case analysis writing were analyzed. RESULTS:The aim of pharmacy case analysis writing was to cultivate students’pharmaceutical thinking and the ability to solve real-world pharmaceutical problems. The key was to reflect the clinical pharmacist’s role in the event. The common problems included inappropriate selection of topics,insufficient evidence in discus-sion,and unclear organization of contents,where teachers should pay more attention to. CONCLUSIONS:Improving the teaching of pharmacy case analysis writing can improve the quality of clinical pharmacy student’s case analysis and cultivate their practical skills.

Objective To determine the diagnostic value of cardiovascular magnetic resonance (CMR) in children with myocarditis. Methods A total of 27 children with myocarditis were examined with cardiac MRI, including 16 new?onset cases and 11 chronic cases, as well as 14 cases with non?myocarditis. Sequences included SSFP in axial, two chamber, four chamber and short axis, T2?weighted triple inversion recovery, T1?weighted spin echo before and after gadolinium injection, and inversion recovery?gradient echo after gadolinium injection(late gadolinium enhancement, LGE) in axial and short axis. Qualitative and quantitative image analysis was performed to obtain focal T2 signal intensity and early enhancement signal intensity(SI) ratio of myocardium to skeletal muscleon EGE and LGE.The sensitivity, specificity and accuracy were calculated. Mann?Whitney and χ2 test were used for statistical comparison. Results The median value of EF was 60.20%(44.40%,70.20%), median value of T2W SI ratio was 2.50(2.04, 3.79),and there were 13 cases with LGE positive findings in myocarditis group. The median value of EF was 73.60%(65.40%,75.85%), the median value of T2WI SI ratio was 1.85(1.77, 2.15), and one case presented LGE positive sign in non?myocarditis group. There were significant statistical differences between the two groups (Z=-2.94,-2.52 ,χ2=5.19 ,P<0.05). The sensitivities for T2WI, EGE, LGE were 81.5%(22/27), 14.8%(4/27) and 48.1%(13/27) respectively. The specificities for T2WI, EGE, LGE were 57.1%(8/14), 100.0%(14/14)and 92.9%(13/14) respectively. The diagnostic accuracies for T2WI, EGE, LGE were 73.2%(30/41), 43.9%(18/41) and 63.4%(26/41) respectively. The best diagnostic performance was obtained when“any?two”of the three sequences were positive in the same patient, yielding a 51.9%(14/27)sensitivity, 92.9%(13/14) specificity, and 65.9%(27/41) diagnostic accuracy.Conclusions The combined CMR approach using T2?weighted imaging, early and late gadolinium enhancement, provides a high diagnostic accuracy and is a useful tool in the diagnosis and assessment of children with myocarditis.

Objective In order to explore the association between complement C3 and primary open angle glaucoma (POAG),the serum complement C3 level was detected and the polymorphism of the C3 exon gene was analyzed in patients with POAG.Methods A prospective case-control study was designed.A total of 45 patients with POAG visiting Eye &ENT hospital of Fudan University were collected from December 2014 to December 2015,and 45 age-/gender-matched healthy subjects from yearly health screening were collected as normal controls.Serum C3 concentration was detected by immunoturbidimetric assay.Meanwhile,genomic DNA was extracted from peripheral blood leukocytes,and sequencing for C3 exons was followed with PCR to analyze the gene polymorphism.Statistical analysis was performed by use of SPSS 20.0 software.Student's t test was used to evaluate the difference of serum C3 level between two groups.Chisquare test was used to analyze the difference in the distribution of C3 exon gene polymorphism between two groups.The one-way ANOVA was utilized to analyze the difference of serum C3 level among different genotypes of C3 exon.Results The serum level of C3 in POAG (104.81 ± 29.15)mg/dl was significantly lower (t =-3.162,P =0.002) compared to controls (121.06 ± 18.39) mg/dl.There were a total of seven single nucleotide polymorphisms (SNPs) (rs2230201,rs2230204,rs2230205,rs428453,rs423490rs7951,rs539822147) within the C3 exon gene region,but no mutation was detected.There was no difference in the frequency and distribution of these SNPs between POAG and controls,as well as,there was also no significant difference in serum C3 level among these SNPs genotypes.Conclusions Decreased serum C3 level in POAG patients indicated that complement C3 might be involved in the pathomechanism of glaucoma.No significant abnormality of C3 exon gene was detected,so the gene polymorphism having an impact on serum C3 level could be excluded as a reason probably.

Objective:To investigate the clinical relationship between homocysteine (Hcy) metabolizing enzyme gene polymorphism and poor prognosis of multiple myeloma (MM) in Han nationality.Methods:One hundred and twenty-eight MM patients of Han nationality admitted to the First Affiliated Hospital of Hebei North University from February 2018 to March 2020 were selected as the disease group, and 120 healthy volunteers of Han nationality were recruited as the control group at the same time. Blood samples were taken to detect plasma Hcy level and Hcy metabolizing enzyme gene polymorphism, including methylenetetrahydrofolate reductase(MTHFR) C677T, MTHFRA1298C, methionine synthase reductase(MTRR) A66G, cystathionine beta-synthase(CBS) 844ins68 and methionine synthase (MS) A2756G. The patients in the disease group were treated with conventional methods , followed up for 1 year after treatment, and the incidence of poor prognosis was counted. Plasma Hcy level, genotype distribution and allele frequency of Hcy metabolic enzymes were compared between the two groups. Logistic multiple regression analysis was used to analyze the association of Hcy metabolizing enzyme gene polymorphism with MM poor prognosis in Han nationality.Results:The plasma Hcy level in the disease group was higher than that in the control group: (15.01 ± 2.98) μmol/L vs. (8.45 ± 1.69) μmol/L, there was statistical difference ( P<0.05). The frequency of TT genotype and T allele of MTHFRC677T locus in the disease group were higher than those in the control group : 26.56% vs. 6.67% , 29.30 vs. 16.25%; while the frequency of CT genotype in the disease group was lower than that in the control group: 5.47% vs. 19.17% , there were statistical differences ( P<0.05). There were no significant differences in genotype distribution and allele frequency of other gene loci between the two groups ( P>0.05). The incidence of poor prognosis in the disease group was 49.22%(63/128). Age, platelet count, serum β 2 microglobulin level, serum κ light chain level, plasma Hcy level and TT genotype of MTHFRC677T locus were the influencing factors of poor prognosis in the disease group ( OR = 7.286, 0.545, 6.841, 6.284, 8.117 and 8.440; P<0.05). Conclusions:The plasma Hcy level, TT genotype and T allele frequency of MTHFRC677T locus in MM patients of Han nationality are higher than those in healthy people, while the CT genotype frequency is lower than that in healthy people. The poor prognosis of MM in Han nationality is related to plasma Hcy level and TT genotype of MTHFRC 677T locus.
