Value of serum pepsinogen Ⅰ, Ⅱ and gastrin-17 in screening precancerous lesions of gastric cancer in physical examination population / 中国医师进修杂志

Objective:To evaluate the value of serum pepsinogen Ⅰ and Ⅱ combined with gastrin-17 in screening precancerous lesions of gastric cancer in physical examination population.Methods:Serum pepsinogen, gastrin-17 and Helicobacter pylori (Hp) antibody were detected in 18 354 physical examination people from July to December 2017 in Wenrong Hospital, Hengdian, Dongyang. The patients were divided into youth group (18 to 39 years old), middle-aged group (40 to 59 years old) and elderly group (≥60 years old) according to their ages. The correlation between the serological level of the above indexes and age was analyzed; according to the new ABC method, the test results were divided into groups A, B, C and D. The patients in group C and D were examined by gastroscopy. The differences of gastric mucosal atrophy or intestinal metaplasia and other precancerous lesions detected by gastroscopy in different age groups were compared.Results:Finally, 18 354 cases were enrolled, including 9 614 males and 8 740 females. With the increase of age, the proportion of group C and D increased gradually. In group C, 181 cases underwent gastroscopy, including 39 cases of atrophic gastritis, 29 cases of intestinal metaplasia and 3 cases of dysplasia/intraepithelial neoplasia, the detection rate of precancerous lesions was 39.23%; in group D, 94 cases underwent gastroscopy, including 22 cases of atrophic gastritis and 13 cases of intestinal metaplasia, the detection rate of precancerous lesions was 37.23%. The proportion of gastric precancerous lesions in group C and D was 29.63% in the young group, 69.70% in the middle-aged group and 71.58% in the old group, respectively. There was significant difference compared with the young group ( P<0.01); atypical hyperplasia occurred in 2.02% and 9.47% of the middle-aged group and the elderly group. Conclusions:The combined detection of serum pepsinogen Ⅰ and Ⅱ and gastrin-17 levels is of great value in the screening of precancerous lesions of gastric cancer; when this method used for early gastric cancer screening in healthy population, it is necessary to consider the influence of age for the risk stratification of gastric cancer.

Analysis on other sperm parameters of sperm with different sperm acrosomal arginine enzyme activity / 国际检验医学杂志

Objective To evaluate the value of sperm acrosomal arginine enzyme activity in the diagnosis and treatment of male infertility by studying its relationship with sperm motility and morphology.Methods The sperm acrosomal arginine enzyme activity was detected by chemical colorimetric method,and the routine parameters of sperm and sperm morphology were detected by computer-aided analysis.Results There were significant differences on sperm concentration,motility and progressive motility between normal sperm acroso-mal arginine enzyme activity group and abnormal sperm acrosomal arginine enzyme activity group(P<0.05). The percentage of deformities in head,neck and middle segment were significant different between normal sperm acrosomal arginine enzyme activity group and abnormal sperm acrosomal arginine enzyme activity group (P<0.05).Conclusion T he activity of sperm acrosin is a very efficient marker in sperm quality,and an effec-tive indicator of the evaluation of sperm fertilization potential and the diagnosis of male infertility.

Analysis of FOXL2 gene mutation and genotype-phenotype correlation in a Chinese pedigree affected with blepharophimosis-ptosis-epicanthus inversus syndrome / 中华医学遗传学杂志

<p><b>OBJECTIVE</b>To detect FOXL2 gene mutation in a Chinese pedigree affected with blepharophimosis-ptosis-epicanthus inversus syndrome (BPES) type I, and to explore its genotype-phenotype correlation.</p><p><b>METHODS</b>Peripheral blood samples were obtained from 3 patients and 19 healthy members from the pedigree for the isolation of genomic DNA. All exons and flanking sequences of the FOXL2 gene were amplified by PCR with 7 pairs of overlapping primers and sequenced.</p><p><b>RESULTS</b>DNA sequencing indicated that the BPES phenotype in this pedigree was caused by a hotspot c.843_859dup17 mutation. The same mutation was not found among the healthy members of the pedigree.</p><p><b>CONCLUSION</b>The c.843_859dup17 frameshift mutation probably underlies the BPES type I in this Chinese pedigree, which may manifest as either BEPS type I or type II.</p>

Exophthalmos, low back pain and hypertension: a report of one case with literature review / 中华风湿病学杂志

Objective By analyzing the clinical manifestations and pathologic features of Erdheim-Chester's disease (ECD) to improve the recognition of the disease.Methods The clinical characteristics,diagnosis and treatment of a young male with ECD were reported and the related literature was reviewed.Results A previously healthy young male patient with bilateral exophthalmos,blurred vision of right eye,polyuria and hypertension without obvious causes for nine months were admitted into our hospital.He developed low back pain two months ago.Thoracic vertebra Magnetic resonance imaging (MRI) showed multiple nodules extending from the 2th-7th thoracic vertebrae intra-medullary.MRI of the brain showed multiple masseswith abnormal intensities within the retro-ocular intraconal muscle cone,sellar and cavernous sinus,maxillary sinus.Biopsy specimens from the right orbital lesion demonstrated proliferation of fibrous connective tissue and fat tissue infiltrating with lymphocytes,plasma cells,eosinophils,foam cells,spindle cells,and multinucleated giant cells accompanied by fat necrosis.Immunohistochemistry showed infiltrated lymphocytes stained positive for CD68,CD20,CD3,LCA and negative for CD1a,S-100 protein and langerin.The clinical symptoms of exophthalmos and low back pain relieved after treated with methylprednisolone and interferon-α.Conclusion Understanding the characteristics of ECD can help to make the correct diagnosis and treatment.

The diagnostic value analysis on serum total type Ⅰ amino terminal extension of the peptide and vitamin D3 in chronic obstructive pulmonary disease patients suffered from osteoporosis / 中国医师进修杂志

Objective To explore the relationship between osteoporosis and serum total type Ⅰ amino terminal extension of the peptide,vitamin D3 and smoking index in the patients with chronic obstructive pulmonary disease (COPD).Methods One hundred and fifty patients with COPD (test group) and 150 healthy people (control group) were selected.The total type Ⅰ amino terminal extension of the peptide was measured by electrochemical luminescence,and enzyme-linked immunoassay was adopted to determine the vitamin D3.The 150 patients with COPD were divided into slight group (45 cases),moderate group (52 cases) and severe group (53 cases) according to the severity of COPD.In 150 patients with COPD,120 patients with smoking were divided into 3 groups according to smoking index:A group smoking index ＜ 360,36 cases;B group smoking index 360-400,34 cases;and C group smoking index 401-560,50 cases.The levels of serum total type Ⅰ amino terminal extension of the peptide and vitamin D3 were compared and correlation was analyzed.Results The vitamin D3 and the total type Ⅰ amino terminal extension of the peptide levels in test group were significandy lower than those in control group:(35.37 ± 12.11) mg/L vs.(45.88 ± 12.55) mg/L and (38.16 ± 11.12) mg/L vs.(45.23 ± 12.33) mg/L,and there were statistical differences (t =2.74 and 4.64,P＜ 0.01).The levels of vitamin D3 and the total type Ⅰ amino terminal extension of the peptide in slight,moderate and severe group were decreased in turn,and the levels of total type Ⅰ amino terminal extension of the peptide and the vitamin D3 were positively associated with the severity of COPD (r =0.185 and 0.257,P ＜ 0.05).The levels of vitamin D3 and total type Ⅰ amino terminal extension of the peptide in A,B and C group were decreased in turn,and the levels of total type Ⅰ amino terminal extension of the peptide and the vitamin D3 were positively associated with smoking index (r =0.159 and 0.172,P ＜ 0.05).Conclusion COPD patients are easier to suffer from osteoporosis compared with healthy population,and the serum vitamin D3 and total type Ⅰ amino terminal extension of the peptide can forecast the osteoporosis in COPD patients.
