ABSTRACT
The epidemic of the coronavirus disease 2019 （COVID-19） has presented great challenges to the public health throughout the world. Therefore， it is crucial to foster high-level and multi-disciplinary public health talents to further improve public health. Herein， we summarize the current situation and challenges for public health education and prospect the requirements for training public health talents in China. Colleges and universities bear the responsibility for training public health talents， which is essential for the construction of public health system. In this context， we introduce the education for public health and the Doctor of Public Health （DrPH） program at Fudan university.
ABSTRACT
<p><b>OBJECTIVE</b>To explore the clinical efficacy differences of scalp acupuncture on brain injury in premature infants with different months of age.</p><p><b>METHODS</b>According to the corrected months of age, 90 cases of premature infants with brain injury were divided into a group A (3 through 6 corrected months of age), a group B (7 through 9 corrected months of age) and group C (10 through 12 corrected months of age), 30 patients in each one. Based on the conventional early intervention, the infants in the group A were treated with scalp acupuncture at , motor area; the infants in the group B were treated with scalp acupuncture at , motor area and foot motor sensory area; the infants in the group C were treated with scalp acupuncture at , motor area, foot motor sensory area and balance area. All the treatment was given once every other day, and totally 30 treatments were given. The Alberta infant motor scale (AIMS), development quotient (DQ) of each function indexes in Gesell developmental scale (GDS) were observed before and after treatment; the clinical efficacy of each group was compared and the correlation between clinical efficacy and months of age was analyzed.</p><p><b>RESULTS</b>Compared before treatment, the total score of AIMS and DQ of each function indexes of GDS were all improved in the three groups after treatment (all <0.01). After treatment, the differences of total score of AIMS and DQ of each function indexes of GDS among the three groups were significant (<0.05, <0.01), and the results in the group A were higher than those in the group B and the group C (<0.05, <0.01). The total effective rate was 96.3% (26/27) in the group A, which was higher than 89.7% (26/29) in the group B and 83.3% (25/30) in the group C. The correlation analysis indicated less months of age was significantly corelated with better efficacy (<0.05).</p><p><b>CONCLUSION</b>Scalp acupuncture has superior improvement on the recovery of brain damage in premature infants, especially for those with 6 months of age or less.</p>
ABSTRACT
The clinical utility of macrolide antibiotics has declined due to the appearance of resistant isolates.A spiramycin Ⅰ-resistant Staphylococcus aureus ATCC29213-R was induced and isolated with increasing the concentration of spiramycin Ⅰ,which exhibits an A→C transversion at position 2089 in the 23S rRNA gene,which is first reported in the S.aureus.A RNA-seq based transcriptomic analysis was performed to understand the overall response of resistant bacteria to spiramycin Ⅰ treatment with subinhibitory dosage.Inn this study,There are a total of 322 up-regulated and 82 down-regulated genes in spiramycin Ⅰ-treated S.aureus ATCC29213-R and 426 up regulated,838 down-regulated in spiramycin Ⅰ-treated S.aureus ATCC29213,which were identified differentially expressed compared to their control with a minimum 2-fold change (Q ＜ 0.05).Interestingly,The data showed that argH and argG transcripts,in the arginine biosynthetic pathway,were decreased by 13.51-fold and 21.45-fold,respectively,compared to the control,while the expression level of three genes involved in arginine catabolism,arcA,arcC,and argF,increased by 35-fold,18.05-fold and 30.84-fold,respectively.The results revealed that spiramycin Ⅰ could trigger the up-regulation of the genes of ACME-Arc system which allows S.aureus to survive in acidic environments of human skin.This suggesed the arginine-deiminase pathway may be a potential target for treatment of the resistant S.aureus.
ABSTRACT
@#Recent advances in immunology and genetics have verified that the innate immune and adaptive immune responses that mediated by T cells, have been considered to play an important role in inducing inflammatory bowel disease. It’s difficult to cure the disease due to the complexity of the disease. However, the development and application of medicine, which target the immune response in the colon, attract great attention in recent years. In present, there are two types of targeting drugs in the intestinal immune systems: one of them targets the intestinal innate immune system, which includes targeting signal transduction, signal molecule and lymphocytes while the other targets adaptive immune system that includes inhibition of intenstinal T cell activation, differentiation and regulation of T cell cytokines and balance of T cell. This article mainly gives a comprehensive overview in four aspects, which include the intestinal innate immune response, adaptive immune response, drugs targeting in the intestinal innate and adaptive immune response. Furthermore, research directions are also pointed out in the review.
ABSTRACT
Programmed death-1(PD-1)is a major co-suppression receptor expressed on T cells.Binding with its ligands (PD-L1 and PD-L2),PD-1 can inhibit T cell proliferation,activation and cytokine secretion.In normal organs,PD-1 /PD-Ls signaling pathway plays an important role in maintaining immune tolerance,while during tumorigenesis,it can suppress T cell immune response and promote tumor immune escape.This article reviewed the research progress on PD-1 /PD-Ls signaling pathway,comprised of structure and expression of PD-1 /PD-Ls, mechanism of the signaling pathway,as well as the expression characteristics of soluble form of PD-1 /PD-L1 (sPD-1 /sPD-L1),and summarized the categories of anti-PD-1 /PD-Ls antibodies and their clinical trials in canc-er immunotherapy.
ABSTRACT
Objective To investigate the hospitalized patients incidence of nutritional risk and nutritional support in six departments (general surgery, thoracic surgery, gastroenterology, neurology, urology and respirology) in a middle hospital and in the medical/surgical departments in a small hospital, so provide reference for rational nutritional support for patients. Method Nutritional Risk Screening 2002 was used to assess the existence of nutritional risk and the necessity of nutritional support. Results The overall prevalence of the nutrition risk was 25% in the six departments in the middle hospital; more specifically, the prevalence of nutrition risk arranged from 18% to 31% in these six departments: 31% in the department of respiratory medicine, 29% in the department of neurology, 27% in the department of urology, 23% in the department of thoracicsurgery, 22% in the department of gastroenterology, and 18% in the department of general surgery. For those at nutritional risk, the nutritional support rate was 24%. For non-risky patients, 9% received nutritional support. The overall prevalence of nutrition risk was 18% in the small hospital; more specifically, the prevalence of nutrition risk was 29% in the department of internal medicine and 7% in the department of surgery. For those at nutritional risk, the nutritional support rate was 24%.For non-risky patients, the nutritional support rate was 4%. Conclusions Certain nutritional risk and malnutrition exist in inpatients in the middle and small hospitals in Shijiazhuang. The applications of parenteral and enteral nutritions still have some problems. It is of particular importance to further promote the application of evidence-based parenteral/enteral nutrition guidelines in middle and small hospitals to standardize the application of nutritional support.
