Objective The author investigated the clinical features of the the patients with acute pancreatitis and hyperlipaemia (hypertriglyceridaemia),in order to intensify the knowledge of the condition.Methods Forty-three patients with acute pancreatitis were randomly selected and assigned into 2 grups,i.e.,those with hyperlipaemia (11cases) and those with billiary type (32 cases).Results Among the 43 cases,7 were acute necrotizing pancreatitis (5 in hyperlipaemia group).Enumeration correlation demonstrated significant positive correlation between hyperglyceridaemia and the necrotizing type of acute pancreatitis (? 2=6.58,P)or diabetics were significantly higher in hyperglyceridaemia group than in acute billiary pancreatitis group, and so was the life-threatening complications.Conclusion ①Hyperglyceridaemia bears significant positive correlation to the necrotizing type of acute pancreatitis and its life-threatening complications as well.②Diet control,reducing body weight and application of anti-hyperlipaemia drugs will be helpful in prevention and treatment of the relapse of the disease.

Objective:To isolate breast cancer stem/progenitor cells from human breast cancer and study their proliferation and differentiation biological characteristics over long-term passages in vitro. Methods:Human breast cancer stem/progenitor cells were enriched in suspension cultures as nonadherent mammospheres(MS). Serial sphere formation assay was performed to determine self-renewal ability of mammosphere-derived cells (MSDC). Differentiation was induced by culturing MSDC in DMEM-F12 supplemented with serum but without growth factors. The ratio of CD44~+/CD24~(-/low) cell population was evaluated by flow cytometry(FCM). Results:The mammospheres were formed after inoculation of primary breast cancer cells into culcutre medium with growth factors but without serum. The mammospheres contained undifferentiated cells similar to stem cells, which had self-renewal and extensive proliferation capabilities. With increasing passages, the cells tended to adhere and differentiate. The number of adhering and differentiating cells increased, and the amount and size of mammospheres decreased. The CD44~+/CD24~(-/low) cell population was enriched in the basal-like molecular subtype of human breast tumors. The biological behaviors of mammospheres varied between different specimens.Conclusion:Cancer cells with stem cell properties of self-renewal, indefinite proliferation and multi-lineage differentiation widely existed in human breast cancer tissues. The biological behaviors varied because of different origin of specimens and changed under the effects of environmental factors.

Objective To investigate the association between the single nucleotide polymorphisms of interleukin-27 (IL-27) gene and susceptibility to systematic lupus erythematosus (SLE) in Guangxi Zhuang population. Methods In total, 135 patients with SLE and 150 age- and sex-matched human controls of Zhuang nationality were recruited in this study. PCR-restriction fragment length polymorphism (RFLP) analysis and DNA sequencing were performed to analyze the IL-27 gene -964 A/G and -2905 T/G polymorphisms.Results Significant differences were observed in the distribution of IL-27 gene -964 A/G polymorphism (x2 =9.88, P ＜ 0.01 ). The relative risk for SLE in carriers of G allele at position 964 of IL-27 gene was 1.725 times that in carriers of A allele at this position (OR = 1.725,95% CI: 1.227 - 2.425). A significant increase was observed in the frequency of 964G/2905G alleles of IL-27 gene in patients with SLE compared with the controls (10.7% vs. 5.3%, P ＜ 0.01 ), and the 964G/2905G alleles were associated with a significantly increased risk for SLE (OR = 2.351, 95% CI: 1.228 - 4.501 ). Conclusions The IL-27 gene -964 A/G polymorphism is associated with the development of SLE, and the -964 G allele may increase the genetic susceptibility to SLE.

OBJECTIVE:To explore the feasibility of question-and-answer practice teaching in the pharmacy department of our hospital. METHODS:The practice teaching of pharmacy department was taken as a pilot,and the question-and-answer practice teaching was used in emergency and outpatient pharmacies,inpatient pharmacy,PIVAS,drug warehouse,clinical pharmaceutics room,preparation room and drug testing laboratory. The effects of the practice teaching on internships,teachers,pharmacy depart-ments and patients were excavated. RESULTS & CONCLUSIONS:Satisfaction of teachers,pharmacy,patients and clinics for the question-and-answer practice teaching was 100%,and satisfaction of internships was 94.5%. The question-and-answer practice teaching has improved their professional knowledge and competence,resolved difficulty of patients about drug counseling and helped the improvement of overall business level in department.

Objective To report three cases of fulminant ulcerative colitis (FUC) treated with infliximab (IFX) and the positive result for clinical purpose. Methods Three patients with FUC were infused with IFX (5 mg/kg) at interval of 0, 2, 6 wk. Sulfasalazine or probiotics was used for the maintanance of remission. The mucosal healing was evaluated by endoscopy and patholoic examination. ResultsComplete remission was found in 3 patients with FUC. Eight weeks after IFX withdraw, complete remission was found in two of three cases demonstrated by endoscopy, except for one case died from refractory ventricular tachycardia. The remaing 2 cases showed no active manifestation during 8 months' follow-up. Conclusion IFX therapy results in complete remission in 3 cases with FUC. However, further randomized control study is warranted for concrete evaluation on salty and application clinically.

Objective To explore the association of CD40 gene single nucleotide polymorphisms (SNPs) and haplotypes with the susceptibility to systemic lupus erythematosus (SLE),as well as the association of serum levels and genotypes of CD40 with the occurrence of SLE.Methods A multiplex PCR single-base extension assay (PCR-SBE) and DNA sequencing were performed to analyze 4 SNPs of the CD40 gene,including rs1883832 C/T,rs13040307 C/T,rs752118 C/T and rs3765459 G/A,in 205 patients with SLE (SLE group) and 220 healthy human controls (control group).Enzyme-linked immunosorbent assay (ELISA) was conducted to measure serum levels of CD40 in these subjects.Results Compared with the control group,the SLE group showed significantly increased serum levels of CD40 (P ＜ 0.05).There were significant differences in genotype and allele frequencies of the SNP rs1883832 C/T in the CD40 gene between the SLE group and control group (all P＜ 0.01).Relative risk analysis showed that the risk of developing SLE in rs1883832 T allele carriers was 1.517 times that in rs1883832 C allele carriers (OR =1.517,95％ CI:1.157-1.990,P=0.003).Moreover,serum levels of CD40 were significantly higher in rs1883832 T allele carriers than in rs1883832 C allele carriers (P ＜ 0.01).The risk of developing SLE was significantly increased in TCCA haplotype carriers compared with the healthy controls (OR =2.322,95％ CI:1.181-4.564,P=0.012).Conclusion The CD40 gene rs1883832 C/T polymorphism and its TCCA haplotype were both associated with the occurrence of SLE,and the rs1883832 T allele may be a gene predisposing to SLE.
