AIM: To study the effect of peach seed (semen Persicae) on gene expression of mouse with sarcoma 180 by means of DNA microarray. METHODS: DNA microarrays were made by spotting PCR products of 4096 mice cDNA noto a specially treated glass slides. The probes were prepared by labeling experimental and control group tumor tissue mRNA with Cy3 dUTP and Cy5 dUTP separately through reverse transcription. The arrays were then hybridized against the cDNA probe mixture and the fluorescent signals were scanned. The data obtained were analyzed from two repeated experiments. RESULTS: 64 genes were obtained by computer processing. CONCLUSION: These genes identified through this approach are considered as potential candidates for PSPA anti tumor effect.

Objective:To investigate the efficacy of methotrexate combined with mifepristone in the treatment of ectopic pregnancy and its effect on serum human chorionic gonadotropin (β-HCG) and cancer antigen 125 (CA125) levels and endometrial thickness.Methods:Eighty-two patients with ectopic pregnancy who received treatment in Ningbo Yinzhou No. 2 Hospital, China from August 2017 to August 2019 were included in this study. They were randomly assigned to receive treatment with methotrexate (control group, n = 41) or methotrexate combined with mifepristone (observation group, n = 41). Clinical efficacy was evaluated, and adverse reactions and clinical recovery indexes were observed in each group. Before and after treatment, serum biochemical indexes, endometrial thickness and mass diameter were compared between the observation and control groups. Results:Clinical efficacy in the observation group was significantly higher than that in the control group [95.12% (39/41) vs. 75.61% (31/41), χ2 = 6.248, P < 0.05]. The incidence of adverse reaction in the observation group was significantly lower than that in the control group [4.88% (2/41) vs. 19.51% (8/41), χ2 = 4.100, P < 0.05]. After treatment, serum β-HCG, CA125, progesterone and vascular endothelial growth factor levels in the control and observation groups were (1 106.26 ± 122.36) U/L and (902.65 ± 61.32) U/L, (32.26 ± 6.86) kU/L and (28.26 ± 5.26) kU/L, (15.33 ± 3.01) nmol/L and (10.33 ± 1.92) nmol/L, (85.36 ± 16.41) ng/L and (65.33 ± 12.22) ng/L, respectively, which were significantly lower than those before treatment ( t = 56.964 and 82.206, 12.380 and 17.642, 9.976 and 19.471, 7.490 and 12.912, all P < 0.05). After treatment, serum β-HCG, CA125, progesterone and vascular endothelial growth factor levels in the observation group were significantly lower than those in the control group ( t = 10.624, 3.304, 8.967, 6.991, all P < 0.05). After treatment, endometrial thickness and mass diameter in the control and observation groups were (8.23 ± 1.81) mm and (6.25 ± 1.25) mm, (2.21 ± 0.52) cm and (1.52 ± 0.35) cm respectively, which were significantly lower than those before treatment ( t = 3.555 and 15.118, 11.631 and 24.167, both P < 0.05). After treatment, endometrial thickness and mass diameter in the observation group were significantly less or smaller than those in the control group ( t = 6.248 and 7.861, both P < 0.05). After treatment, symptom disappearance time, serum β-HCG recovery time, urine β-HCG negative time, pelvic mass disappearance time and hospital stay in the control and observation groups were (7.26 ± 1.92) d and (4.23 ± 0.85) d, (16.25 ± 3.82) d and (12.33 ± 2.21) d, (15.36 ± 3.26) d and (10.66 ± 2.12) d, (24.12 ± 4.12) d and (18.66 ± 3.61) d, (29.58 ± 5.68) d and (23.52 ± 4.36) d, respectively. After treatment, symptom disappearance time, serum β-HCG recovery time, urine β-HCG negative time, pelvic mass disappearance time and hospital stay in the observation group were significantly shorter than those in the control group, respectively ( t = 10.305, 6.343, 8.631, 7.118, 6.044, all P < 0.05). Conclusion:Methotrexate combined with mifepristone is highly effective in the treatment of ectopic pregnancy because it can reduce adverse reactions, decrease serum β-HCG, CA125, progesterone and vascular endothelial growth factor levels, promote the recovery of serum β-HCG to normal level, reduce endometrial thickness, and promote adnexal mass disappearance, which are conducive to the early recovery of patients, with good clinical safety.

Objective To analyze the clinical characteristics of autoimmune hepatitis (AIH), primary biliary cirrhosis (PBC), primary sclerosing cholangitis (PSC) and AIH/PSC or/PBC overlap syndrome in order to further understand the autoimmune liver diseases (AILD). Methods One hundred and nine patients with AILDs confirmed pathologically were collected between Jan. 2004 and June 2006. Of 109 patients, AIH was found in 27 eases, PBC in 67 cases, PSC in 4 eases, AIH-PSC overlap syndrome in 1 case and AIH-PBC overlap syndrome in 10 cases. The clinical and laboratory data of all patients were assessed retrospectively. Results The AILD was predominantly found in middle-aged women (73.3% ,80/109), and the main clinical manifestations were jaundice, malaise, anorexia and pruritus. The age distribution of patients with AIH showed a single peak at 50 years. Elevated serum gamma globulin and IgG were found in patients with AIH, of whom 62.9% (17/27) were positive for anti-nuclear antibody (ANA) and 3 were positive for liver-kidney microsomes type 1 antibody. The main histological changes in severe AIH cases included interface hepatitis (77.7 %) and bridging necrosis. Most of the PBC patients were presented with elevated serum alkaline phosphatase, glutamyl transpeptidase and IgM. Fifty patients (74.6%) were positive for anti-mitochondrial antibody (AMA) and AMA-M2. The pathological examination showed that 28. 3% of the cases were in Ⅰ or Ⅱ stage and 71.7% in Ⅲ or Ⅳ stage in patients with PBC who received liver biopsy. The pathologic change of reduction or even disappearing of bile ducts was found in 62. 6% patients with PBC. The clinical and pathological manifestations in patients with AIH-PBC overlap syndrome had both characteristics of PBC and AIH. Three out of 10 patients with AIH-PBC overlap syndrome were positive for ANA and AMA/AMA-M2. Conclusion Since AILD is not rare in Chinese, its diagnosis should be based on the clinical presentation, biochemical, immunological and histologic changes.
