Objective To investigate the expression changes of histidine decarboxylase(HDC)and H+,K+-ATPase in gastric mucosa during the healing of experimental gastric ulcer in rats.Methods The ulcers were caused by applying acetic acid to the serosal surface of the anterior face of the rat gastric body.At different time points during ulcer healing,HDC and H+,K+-ATPase mRNA and protein expressions were studied by using reverse transcription-polymerase chain reaction and Western blot respectively.Results An ulcer crater developed on the anterior face of the gastric body on day 1 after the induction of ulcers,and the ulcer area was biggest on day 3.On day 12,most of the gastric ulcers had healed.Compared with the control group,the HDC and H+,K+-ATPase mRNA expression in the gastric mucosa of ulcer rats showed a decrease on day 1,and increased back to initial level on day 9.The protein expression of HDC and H+,K+-ATPase in gastric mucosa of ulcer rats decreased immediately on day 1,more on day 6,and returned to the initial levels on day 12.Conclusion The mRNA and protein expressions of HDC and H+,K+-ATPase decrease in the healing process of gastric ulcers,resulting in accelerated ulcer healing through inhibiting gastric acid secretion.

A 36-year-old female presented with multiple dark brown papules on the chest and abdomen for more than 10 years,which had gradually increased in number.Physical examination revealed dozens of dark brown,flat papules measuring 1-3 mm in diameter in the chest and abdomen.Most of the lesions had a smooth surface,and some lesions gave a papilloma-like appearance,with no confluent trend.Biopsy of abdominal lesions showed mild hyperkeratosis of epidermis,acanthosis,extension of epidermal protrusions forming a reticulated appearance,horn pseudocysts in prickle cell layer,enhanced pigmentation of basal layer,and a sparse lymphocytic perivascular infiltrate in superficial dermis.A diagnosis of dermatosis papulosa nigra (DPN) was made.

Objective To explore the expressions of stromal cell derived factor 1 α (SDF-1α) and cysteine-X-cysteine chemokine receptor 4 (CXCR4) in the peripheral blood of patients with systemic lupus erythematosus (SLE).Methods Forty hospitalized SLE patients were recruited and twenty healthy volunteers were enrolled as normal controls.The percentage of CD3+CD4+CXCR4+,CD3+CD8+CXCR4+ and the plasma concentration level of SDF-1α in the control group and SLE patients were detected by flow cytometry and ELISA.The relationship between SDF-1α/CXCR4 and SLEDAI was explored.Kruskal-Wallis H,Pearson's and Mann-Whitney U test were used for statistical analysis.Results the expression of SDF-1α [329 (127,539) pg/ml] and CXCR4 [CD3+CD4+CXCR4+:4.20(2.01,6.35)％,CD3+CD4+CXCR4+:2.70(1.68,4.20)％] were significantly elevated in SLE patients when compared to the normal controls (Z=-6.277,-5.707,-4.885,respectively,all P=0.000),and were significantly increased in highly active SLE patients than less active SLE (Z=-5.414,-5.256,-5.312,P＜0.01).The expression of SDF-1α and CXCR4 in the butterfly erythema group,anemia group and proteinuria group were significantly higher than the normal group (P＜0.05).Both SDF-1αand CXCR4 were positively correlated with SLEDAI (r=0.857,0.830,0.861,respectively,all P＜0.01).Conclusion The expressions of SDF-1α and CXCR4 increase significantly in the peripheral blood of SLE patients and there is close relationship between SDF-1α/CXCR4 and disease activity,organ damage.The results of this study suggestthat SDF-1α/CXCR4 may play an important role in the pathogenesis of SLE.

ObjectiveTo explore the clinical presentation, diagnosis, treatment, and outcome of the Barth syndrome (BTHS).MethodsClinical data were collected and analyzed from 3 patients with conifrmed genetic diagnosis of BTHS from June 2013 to October 2014.ResultsAll of the 3 patients were males and two of them were twins. The main clinical manifes-tations of the 3 patients were cardiomyopathy and heart failure, accompanied by different degrees of trabeculations of the left ventricle. Two of them were diagnosed of left ventricular noncompaction (LVNC). All of the 3 patients presented with motor retardation, muscle weakness, growth delay and signiifcantly increased urinary excretion of 3-methylglutaconic acid (3-MGC). One patient was found to have neutropenia. All 3 patients hadTAZ gene mutations which included a novel missense mutation (c.527A>G, p.H176R) detected in the twins and a known nonsense mutation (c.367C>T, p.R123X) identiifed in the other patient. All of the mutations were inherited from their mothers. During the follow-up, the twins died at 7 months old and 7.5 months old respectively. The other patient was still alive.ConclusionBTHS is one of the causes of cardiomyopathy in children. In the male patients who presented with muscle weakness, neutropenia, and increased urinary excretion of 3-MGC, especially in those com-bined with LVNC, BTHS should be screened.
