Objective To evaluate the diagnostic value of gastrin?17( G?17) and pepsinogen( PG) for gastric cancer. Methods A multicenter cross?sectional study of patients with continuous stomach discomfort from four centers including Changhai Hospital Affiliated to Second Military Medical University, the First Hospital Affiliated to Anhui Medical University, Qinghai Provincial People′s Hospital and the First Hospital Affiliated to Zhejiang University of Chinese Medicine from May 2014 to September 2015 was conducted. Before gastroscopy, fasting serum gatrin?17 and pepsinogen were analyzed by enzyme?linked immunosorbent assay(ELISA). The efficacy of G?17 and PG were evaluated according to endoscopic and pathological results. Results Based on the results of the pathological diagnosis, 1 122 cases were enrolled and divided into chronic atrophic gastritis group ( 548 cases ) , chronic non?atrophic gastritis group ( 370 cases), and gastric cancer group(204 cases). Serum G?17 and PGⅡ levels significantly increased(P<0?05) and PGR significantly decreased( P<0?05) in gastric cancer group compared with other groups. There was no significant difference in PGⅠlevel among three groups. The cut?off value of G?17 to diagnose gastric cancer was 7 pmol/L. The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of G?17 for gastric cancer were 59?31%, 70?59%, 68?54%, 30?95% and 88?65% respectively. The cut?off value of PG Ⅰ/PG Ⅱ( PGR ) to diagnose gastric cancer was 7. The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of PGR for gastric cancer were 41?18%, 83?01%, 75?40%, 35?00% and 86?39% respectively. The cut?off value of PGⅡto diagnose gastric cancer was 10 μg/L. The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of PGⅡfor gastric cancer were 73?53%, 53?05%, 56?77%, 25?82% and 90?02% respectively. If G?17>7 pmol/L and PGR<7 was regarded as the cut?off value of diagnosis of gastric cancer, the sensitivity, specificity, accuracy, positive predictive value and negative predictive value were 25?00%, 91?29%, 79?23%, 38?93%and 84?56%respectively. If G?17>7 pmol/L and PGⅡ>10μg/L was regarded as the cut?off value, the sensitivity, specificity, accuracy, positive predictive value and negative predictive value were 48?04%, 79?74%, 73?98%, 34?51% and 87?35% respectively. If PGR<7 and PGⅡ>10 μg/L was regarded as the cut?off value, the sensitivity, specificity, accuracy, positive predictive value and negative predictive value were 33?82%, 84?86%, 75?58%, 33?17% and 85?23% respectively. Based on logistic regression analysis of the independent variables of high serum G?17 value(>7 pmol/L), low serum PGR value(<7) and high serum PGⅡvalue(>10 μg/L), their OR value were 2?592, 2?237 and 1?864 respectively, and high serum G?17 value showed the highest risk of gastric cancer. Conclusion High serum G?17 and PGⅡ, low PGR are indicators of gastric cancer. Combination of G?17 and PGR has the best diagnostic value for gastric cacer. Gastric cancer can be screened in large scale by combining G?17 and PGR in order to improve the early diagnostic rate of gastric cancer and reduce the mortality of gastric cancer in our country.

BACKGROUND:Hepatocyte transplantation has attracted more and more attention as a therapeutic measure for liver failure and genetic metabolic liver diseases.OBJECTIVE:TO evaluate the efficacy and safety of human hepatocyte transplantation in treating hepatitis B related liver failure in one case by a 2-year follow-up.DESIGN:A case-report of 2-year follow-up.SETTING:No.9 Department of Infectious Diseases,Bioengineering Research Room,the 302 Hospital of Chinese PLA.PARTICI PANT:One inpatient with hepatitis B related liver failure was selected from the 302 Hospital of Chinese PLA.and she was diagnosed according the laboratory tests.The transplanted hepatocytes were originated frOm the healthy liver of a 24-year-old man,who had signed the protocol for liver donation before death.METHODS:The hepatocyte transplantation was completed in the Department of Radiology,the 302 Hospital of Chinese PLA in December 2004.Liver was isolated to obtain human primary hepatocytes, and then cryopreserved.The hepatocytes were transplanted into recipient spleen via femoral vein after resuscitation.The clinical symptoms,changes of blood biochemical indexes,and changes of spleen MRI signals were observed before and after operation.The patient was reexamined every half a year after operation, including liver function, blood coagulation function,B-mode ultrasonography,gastroscopy and MRI,and she was followed up for 2 years. MAIN OUTCOME MEASURES:Liver function,blood coagulation function, imaging indexes, immunological indexes,complication and rejection.RESULTS:①Totally(1-2)×1010 hepatocytes were harvested,and the viability of rewarmed hepatocytes was 60%,and finally 2×109 hepatocytes were transplanted.②Two months later,the clinical symptoms of the recipient were obviously ameliorated,and serum bilirubin and aspartate aminotransferase(AST)were obviously decreased,while prothrombin activity was markedly increased.20 months later,the MRI results showed that there was hepatocyte image in spleen.Two years after operation.the total bilirubin level was 20 μmol/L,direct bilirubin level was 7 μmol/L, alanine aminotransferase was 416.75 nkat/L,AST was 533.44 nkat/L,albumin was 37 g/L,prothrombin activity was 90%,which were all obviously ameliorated as compared with those before operation(474.5 μmol/L,340.3 μmol/L,400.08 nkat/L,1 200.24 nkat/L,38 g/L,25%).The patient left the hospital 2 months later and could do light-burdened job.No complications of hydroperitonia and liver function failure, etc.were observed,and no rejection occurred.Several reexaminations by B-mode ultrasonography all indicated the further aggravations of liver cirrhosis and esophageal varices.She was admitted to hospital for twice because of esophageal varices bleeding,and cured by endoscopic variceal sclerosis therapy.CONCLUSION:Hepatocyte transplantation can ameliorate liver function without rejection,but it cannot relieve portal hypertension.

objective: To investigate the status of empathy ability and perceived social support in military college students, and to explore the relationship between empathy ability and perceived social support. Methods: A total of 472 college students were selected from 5 military academies. The Interpersonal Reactivity Index-C (IRI-C) and Perceived Social Support Scale (PSSS) were used to evaluate the empathy ability and the perceived social support ability of military college students. Results: The total scores of IRI-C and PSSS were (51. 2 ± 10. 8) and (65. 8 ±11. 5), respectively. The total scores of PSSS and its three dimensions (family support, friend support and other support) were positively correlated with the total scores of IRI-C and its three dimensions (empathy concern, perspective taking and fantasy) (r = 0. 19-0. 35, Ps ＜ 0. 01). The scores of empathy concern and perspective taking could positively predict the total scores of PSSS (β = 0. 29, P ＜ 0. 001; β = 0. 15, P ＜ 0. 001). Conclusion: It suggests that the empathy ability of military college students is at the middle level. Empathy ability could predict perceived social support in military college students.

Objective To evaluate the efficacy and safety of desonide 0.05％ cream in the treatment of mild to moderate infantile atopic dermatitis (AD).Methods A multicenter,randomized,openlabeled,active-controlled clinical trial was conducted.A total of 120 infants with AD were enrolled from Department of Dermatology,Beijing Children's Hospital,Capital Medical University,Children's Hospital of Chongqing Medical University and Children's Hospital of Fudan University between December 2016 and November 2017.These patients were randomly divided into 2 groups to be topically treated with desonide 0.05％ cream (test group,n =61) and hydrocortisone butyrate 0.1％ cream (control group,n =59),respectively.After the treatment for 1,2 and 3 weeks,the response rate,improvement of eczema area and severity index (EASI) and infants' dermatitis quality of life (IDQOL) were evaluated,and adverse events and reactions were recorded.Statistical analysis was carried out with SAS 9.4 software using confidence interval method and non-inferiority test for the comparison of response rates between the test group and control group,two-sample t test for the comparison of quantitative data between two groups,paired t test for comparing pre-and post-treatment EASI scores and IDQOL scores.If the data were not normally distributed or there was heterogeneity of variance,Wilcoxon rank sum test was used for the comparisons of pre-and posttreatment EASI scores and IDQOL scores before and after the treatment,and chi-square test was used for the comparison of unordered categorical data between the test group and control group.Results At weeks 1,2and 3 after the initial treatment,analysis of the full analysis set (FAS) showed that 46 (86.79％),49(92.45％) and 51 (96.23％) patients in the test group received improvement respectively,and 36 (83.72％),35 (81.40％) and 41 (95.35％) in the control group received improvement respectively.The non-inferiority test showed that the response rate in the test group was non-inferior to that in the control group (non-inferiority boundary value was-0.15).At the baseline,1,2 and 3 weeks,the EASI scores in the test group were 4.57 ± 3.19,0.72 ± 0.89,0.45 ± 0.87 and 0.18 ± 0.40 respectively,and the EASI scores in control group were 4.50 ± 3.29,1.03 ± 1.81,0.62 ± 0.85 and 0.28 ± 0.82 respectively.Paired Wilcoxon rank sum test showed that the EASI scores in the test group and control group significantly decreased after the treatment for 1,2 and 3 weeks compared with those at the baseline (the test group:T =-715.5,-9.4,-715.5,respectively,all P ＜ 0.001;the control group:T =-437.5,-473.0,-472.0,respectively,all P ＜0.001).However,Wilcoxon rank sum test revealed that there was no significant difference in the EASI scores between the two groups at any of the above time points (P ＞ 0.05).Paired Wilcoxon rank sum test showed that IDQOL scores in the test group significantly decreased at the above time points after the treatment compared with those at the baseline (all P ＜ 0.001),while Wilcoxon rank sum test revealed that there was no significant difference in the IDQOL score between the test group and control group (all P ＞0.05).Adverse reactions were observed in 12 (19.7％) patients in the test group,and 10 (16.9％) in the control group,and there was no significant difference in the adverse reactions between the two groups (x2 =0.029,P ＞ 0.05).Conclusion The efficacy of desonide 0.05％ cream in the treatment of mild to moderate infantile AD is equivalent to that of hydrocortisone butyrate 0.1％ cream,so desonide 0.05％ cream can be a treatment option for mild to moderate infantile AD.
