Functional dyspepsia is a common functional gastrointestinal disease , however , the cause of functional dyspepsia has not been fully elucidated .Ghrelin is braingut petide , secreted by major endocrine cells of the stomach ( x/A like cells ) .Its recep-tor is widely distributed in the body .It has many kinds of biological effects , such as regulating growth hormone secretion , feeding and energy balance , affecting neuroendocrine and gastrointestinal function and so on .A growing number of studies have shown that Ghrelin in FD has a positive role in increasing the improvement of food intake and generating hunger , promoting gastric emptying .Ghrelin is a new hot spot in the research of FD .

BACKGROUND:The rapidly developed transplantation of peripheral blood stem cells have been successfully used to substitute bone marrow transplantation and become the first choice method for transplantation of hemopoietic stem cells.It is relatively difficult to collect peripheral blood stem cells from young age and low body mass infants.OBJECTIVE:To investigate the safety and adverse effects of peripheral blood stem cell collection from young age and low body mass through the use of blood cell separator.METHODS:Two type 1 diabetes mellitus infants,aged younger than 2 years old and with body mass less than 15 kg,were treated using autologous hemopoietic stem cell transplantation.The two infants were adequately comforted to lesion the fear of collection.At 1 week prior to collection,calcium agent was orally taken to reduce the incidences of low calcium.Within 24 hours prior to collection,oily food was forbidden,and on the day of collection,milk was forbidden,to avoid chylemia,which influences blood collection.Prior to collection,200 mL 25 Gy y-ray radiated red blood cells suspension was injected into the tube,which was routinely placed in the subclavian vein,to avoid hypovolaemic syndrome and the effects on hematocrit.Individualized collection parameters were set,During collection,blood circulation volume was 3,4 times of systemic blood circulation to ensure sufficient total circulation volume.During isolation,the ratio of ACD to whole blood was kept between 1:11 and 1:13 to prevent sodium citrate poisoning.RESULTS AND CONCLUSION:Peripheral blood stem cells were successfully collected during first intention in each infant.During collection,stable vital signs but no adverse effects were observed.After collection,mononuclear cells weighted 14.71×108/kg and 18.82×108/kg respectively,and CD34+ cells were about 34.13×108/kg and 32.38×106/kg,respectively in each infant.Therefore,it is feasible to collect peripheral blood stem cells from infants of young age and low body mass under sufficient psychological preparation.

System integration is inevitable since there are lots of heterogeneous medical information systems in the complicated medical environment. The current medical communication standards often focus on one aspect of the integration and do not provide a general scheme. Based on the analysis of the application of medical integration, the medical integration model HIM (Healthcare integrating model) is put forward, and the dataflow integration framework, function integration framework and interface integration framework in the HIM are designed subsequently. HIM provides a 3-D scheme for the integration of medical information systems, which not only contains the three aspects of integration application vertically, but covers the whole medical area horizontally.

Background:Oryz-Aspergillus Enzyme and Pancreatin Tablet is a double-deck digestive enzyme pellet containing Oryz-Aspergillus enzyme and pancreatin that has been widely used for treatment of functional dyspepsia (FD)in clinical practice. However,there is no randomized controlled trial focusing on the efficacy of this agent versus other drugs used for treatment of FD such as prokinetics and proton pump inhibitors (PPI). Aims:To compare the efficacy and safety among Oryz-Aspergillus Enzyme and Pancreatin Tablet,Domperidone Tablet and Esomeprazole Magnesium Enteric-coated Tablet, three drugs with different mechanisms of action on FD,in Chinese population. Methods:A total of 82 Helicobacter pylori-negative outpatients fulfilling the diagnostic criteria of FD in Rome Ⅲ were recruited from Nov. 2015 to Jun. 2016 at the First Affiliated Hospital of Zhejiang Chinese Medical University. These patients were randomly allocated into 3 groups,and received Oryz-Aspergillus Enzyme and Pancreatin Tablet (group A),Domperidone Tablet (group B)and Esomeprazole Magnesium Enteric-coated Tablet (group C)orally for 4 weeks,respectively. The improvement of dyspeptic symptoms and adverse events were observed and recorded. Results:After 4 weeks treatment,the overall efficacies for global symptoms in group A,group B and group C were 93. 1%,88. 9% and 69. 2%,respectively,statistically significant difference was existed among the three groups (P < 0. 05). Domperidone Tablet was effective for postprandial fullness and early satiety;Esomeprazole Magnesium Enteric-coated Tablet was sensitive for epigastric pain,epigastric burning,and belching and regurgitation;the efficacies of Oryz-Aspergillus Enzyme and Pancreatin Tablet for all five dyspeptic symptoms were in between. No adverse events were observed during treatment course. Conclusions:Digestive enzymes,prokinetics and PPI have different sensitive symptoms and optimal indications for treatment of FD. The overall efficacy of Oryz-Aspergillus Enzyme and Pancreatin Tablet is superior to that of prokinetics and PPI.

Objective To investigate the novel V617F point mutation of JAK2 gene by real-time PGR in the patients with chronic myeloproliferative disease (CMPD) and evaluate its clinical significance. Methods Genomic DNA from bone marrow or peripheral blood mononuclear cells was extracted from 56 patients with CMPD, including 26 cases of polycythemia vera (PV), 24 cases of essential thrombocythemia (ET), 5 cases of chronic idiopathicmyelofibrosis (CIMF) and 1 case of high eosinophilic syndrome (HES). The exon 14 of JAK2 gene which harbourd V617F mutation were screened by real-time PGR. Results JAK2 V617F mutation was measured in 29 of the 56 patients with CMPD. The prevalence of mutation was 65.38 %(17/26) in PV,37.50 % in ET and 60.00 %(3/5) in CIMF. The proportion of mutation in PV, ET and CIMF are respectively 53.85 %(14/26), 29.17 %(7/24), 40.0 %(2/5) in heterozygotes and 11.54 %(3/26), 8.33 %(2/24), 20.00 %(1/5)in homozygotes. JAK2 mutation was negative in one patient with HES. JAK2 V617F allele burden in PV, ET and CIMF are respectively 2.14×102-1.5×107, 9.80×102-4.4×107 and 4.10×103-3.70×106 copies. Conclusion Real-time PCR is a useful tool for pre cisely assess the grade of mutant allele burden as well as to screen JAK2V617F mutation simultaneously, which is simple and convenient to carry out in clinical laboratories for diagnosis and further evaluations of minimal residual disease in CMPD patients.

The STandards for Reporting Interventions in Clinical Trials Of Moxibustion (STRICTOM), in the form of a checklist and descriptions of checklist items, were designed to improve reporting of moxibustion trials, and thereby facilitating their interpretation and replication. The STRICTOM checklist included 7 items and 16 sub-items. These set out reporting guidelines for the moxibustion rationale, details of moxibustion, treatment regimen, other components of treatment, treatment provider background, control and comparator interventions, and precaution measures. In addition, there were descriptions of each item and examples of good reporting. It is intended that the STRICTOM can be used in conjunction with the main CONSORT Statement, extensions for nonpharmacologic treatment and pragmatic trials, and thereby raise the quality of reporting of clinical trials of moxibustion. Further comments will be solicited from the experts of the CONSORT Group, the STRICTA Group, acupuncture and moxibustion societies, and clinical trial authors for optimizing the STRICTOM.

OBJECTIVE: To investigate the mental health status and its influencing factors among general population and healthcare professionals in Guangdong Province during COVID-19 pandemic. METHODS: A online questionnaire-based survey was conducted from March 11st to March 15th, 2020.The questionnaire consisted of 4 parts to survey the participants'basic information, understanding of COVID-19 outbreak-associated information, cognition of COVID-19 pandemic and status of anxiety and depression.A total of 1433 valid responses were collected, including 706 from the general population and 727 from healthcare professionals.Cronbach's α coefficient and exploratory factor analysis were used for reliability and validity assessment.Chi-square, Wilcoxon and Kruskal-Wallis test were used for univariate analysis and ordinal or nominal logistic regression was used for multivariate analysis of the data. RESULTS: There was no significant difference between the general population and the healthcare professionals in terms of anxiety, depression and cognition of COVID-19 outbreak after adjustment for demographic variables, but the levels of anxiety and depression of these participants were both higher than those before the pandemic.In the participants from the general population, multivariate logistic regressions showed an OR for anxiety of 1.93(1.18, 3.17) among those who spent 1-2 h a day in reading COVID-19-related news, while those who spent over 3 h had an OR value for anxiety of 1.88(1.14, 3.11);the unmarried individuals had a depression OR of 2.19(1.51, 3.18). Inaccurate cognition of COVID-19 outbreak was positive correlated with the occurrence of anxiety and depression.Unmarried individuals and those with higher educational levels had better cognition of COVID-19 outbreak.Among the healthcare professionals, multivariate logistic regressions suggested that insufficient rest time and worries about contracting the virus contributed to the occurrence of anxiety and depression.Among the nursing staff, the OR of obvious depression was 2.99(1.45, 6.18).Compared to healthcare professionals not working in designated hospital for COVID-19, those who work in the designated hospitals had ORs for obvious and severe depression of 0.48(0.25, 0.93) and 0.39(0.17, 0.89), respectively.Concerns over contracting the virus increased the possibility of incorrect cognition of COVID-19. CONCLUSIONS Psychological interventions are essential for both the general population and healthcare professionals, especially for unmarried individuals in the general population and the nursing staff.An excessive exposure to COVID-19-related information may have detrimental effects on the mental health.For healthcare professionals, sufficient rest needs to be ensured, and education programs on COVID-19 should be implemented among both residents and healthcare professionals to improve their mental health.
