Objective To explore the prevention effect of points massage on the cerebral hemorrhage patients with constipation.Methods Totals of 160 cases of acute cerebral hemorrhage within 7 d were randomly divided into observation group (n =80) and control group (n =80).All cases received the routine care,and patients in observation group received the points massage.Then,the incidence of constipation of two groups,the blood pressure and heart rate of observation group before and after intervention were observed.Results The incidence of constipation after cerebral hemorrhage in observation group was 16.25％ and that of the control group was 43.75％,and the difference was statistically significant (x2 =14.40,P ＜ 0.01).Before and after intervention,the heart rate and blood pressure in observation group had no significant difference (t =0.21,-0.28,0.44 ;P ＞ 0.05).Conclusions Points massage is benefit to patients for preventing constipation after cerebral hemorrhage.

Objective To explore the molecular basis of familial hypercholesteraemia(FH)by analyzing the phenotype and genotype relationship through identify the low density liporotein receptor(LDL-r)gene mutation in a FH kindred.Methods A male patient of 15 years old was selected to examine the electrocardiogram,lipid.Color Doppler was used to examine heart and great vessels.The promoter region and the 18 exons of the LDL-r gene were screened by touch-down polymerase chain reaction(PCR)and DNA sequencing.Results The caro-tid intima-media thickness(IMT)was increased to 0.23 cm,while coronary flow velocity reserve(CFVR)was decreased to 1.57,and mode-rate mitral regurgitation was found in the proband.The genetic alteration G→A change at 1 448 of exon 10 causing premature stop codon(W462X).The same heterozygous nonsense mutation was also found in his father.The mutation had been reported in other Chinese patients.In vitro experiments showed that W462X mutation leads to low LDL binding and internalization ability.Conclusions The homozygous mutation(W462X)in exon 10 of the LDL-r gene were identified in the clinically heterozygous FH proband.The W462X mutation is the underl-ying cause of hypercholesterolaemia and clinical AS manifestations.W462X is recurrent mutation among Chinese FH patients.It might be a hot spot mutation in LDL-r in Chinese FH.J Appl Clin Pediatr,2009,24(1):18-20

OBJECTIVETo determine the frequency of the derivative 9 [der(9)] deletion among chronic myeloid leukemia (CML) patients with classic and variant Ph translocations, and assess the correlation between this deletion and clinical prognosis.

METHODSCytogenetic analysis of bone marrow cells was performed by direct method and/or 24 h culture method. RHG banding was used for karyotype analysis. Dual-color and dual-fusion DNA probe was used to perform FISH for investigating the deletion of der(9) in Ph+ CML patients.

RESULTSCytogenetics studies showed typical Ph translocation in 76/105 and variant Ph translocation in 29/105 cases. Interphase-FISH studies showed deletion of der(9) in 12 (15.8%) of 76 patients with classic Ph translocation and in 4 (13.7%) of 29 patients with variant translocation. The frequency of deletion was similar in classic and variant translocations (P > 0.05). When the deletion was seen in the patient, it was present in all the Ph+ metaphases and nuclei. In 3 patients there were mixed cell populations with either 5'-abl or 3'-bcr deletion and all the 3 patients had both 5'-abl and 3'-bcr deletion. The median survival time of patients with deletion was significantly shorter than those without deletion (34 months vs 76 months; P < 0.05).

CONCLUSIONDeletion of der(9) is seen in about 1/6 of Ph+ CML patients in our study on Chinese CML patients, Ph+ CML patients with the deletion have shorter median survival time than those without it, indicating that it is a poor prognostic index.

With the advent of Twenty-First century, more and more genome-wide association studies (GWAS) showed that idiosyncratic adverse drug reactions (ADRs) were closely related with human leukocyte antigen (HLA) alleles, such as the associations of abacavir-HLA-B*5701, allopurinol-HLA-B*5801, and carbamazepine-HLA-B*1502, etc. To explore the mechanisms of these idiosyncratic drug reactions, hapten hypothesis, danger signal hypothesis, pharmacological interaction (P-I) concept and autoimmune mechanism are proposed. In this paper, recent GWAS studies on the HLA-mediated adverse drug reactions and underlying mechanism are reviewed in detail.

OBJECTIVETo report a rare variant of t(15;17), ins(17;15)(q21;q14q22) in an acute promyelocytic leukemia (APL) patient and the results of cytogenetic and molecular genetic studies.

METHODSChromosomes were prepared after 24 hours culture of bone marrow cells and peripheral blood cells. R-banding technique was used to analyze karyotypes. Chromosome painting analysis was performed using whole chromosome paints for chromosomes 15 and 17. PML-RAR alpha and RAR alpha-PML fusion transcripts were detected by reverse transcription-polymerase chain reaction (RT-PCR).

RESULTSKaryotypic analysis using both specimens from bone marrow and peripheral blood leukemic cells revealed 15q- and 17q+. Chromosome painting analysis confirmed that the karyotypic abnormality was ins(17;15). PML-RAR alpha fusion transcript (S type) was detected by RT-PCR, while RAR alpha-PML fusion transcript was not detected.

CONCLUSIONChromosome painting and RT-PCR are reliable methods for characterization of the insertion involving chromosomes 15 and 17 in APL patients.

OBJECTIVETo explore the value of dual-color fluorescence in situ hybridization (D-FISH) in the detection of inv(16) in acute myeloid leukemia (AML).

METHODSEleven AML patients were investigated by D-FISH with two-color break apart probe for MYH11 labeled directly by fluorescein isocyanate (FITC) and a Texas Red. The results were associated or compared with those of cell morphology, cytogenetics, single color fluorescence in situ hybridization (FISH) and reverse transcription-polymerase chain reaction (RT-PCR).

RESULTSFour cases (M4Eo three cases, M2a one case) had inv(16), of which one had trisomy 22 in addition to inv(16), while the other seven cases had no inv(16), of which, five cases (M4Eo three cases, M4 two cases)had a normal karyotype, one (M2a) had 5p+ and trisomy 22, one (M4Eo) had a translocation t(9;22) on G-banded karyotypic analysis. All 11 cases of AML were positive for the rearrangement of inv(16) detected by D-FISH. The average positive cell rate for these 11 AML patients was 93.45% (range 86.6%-98.7%). Of them, four had a minimal deletion of 16p13 in addition to inv(16). The results of D-FISH coincided with those of RT-PCR or single color FISH.

CONCLUSIOND-FISH is a powerful tool for the detection of inv(16) due to its sensitivity and specificity. For raising the detecting rate of inv(16), it is necessary to screen inv(16) rearrangement by D-FISH in all M4- and M2-AML cases or the cases with trisomy 22, no matter whether they are accompanied by bone marrow eosinophilia.
