Postgraduate education is the highest leveled education in the national education hierarchy and bears the historic task of providing top-notch innovative personnel for the country and conducting independent innovation. At present,the medical degree is divided into two types: clinical scientific degree and clinical professional degree. Clinical scientific degree is different from clinical professional degree due to its importance and peculiarities. Therefore,education for postgraduates with clinical scientific degree faces many problems in enrollment,research and clinical capacity develop-ment and evaluation system. Through reforming enrollment plan,strengthening capacity building and establishing sound clinical education evaluation system can further improve training quality for post-graduates with clinical scientific degree.

BACKGROUND:High-density lipoprotein is related to lipid metabolism, but its function cannot be restricted to the scope of lipid metabolism. Simultaneously, exercise regulation has effects on the activity and amount of high-density lipoprotein, but the optimal movement pattern needs to be studied. OBJECTIVE:To offer the theoretical support for formulating fitness training and prospect the possible direction and reference in fol ow-up studying the biological function and exercise regulation of high-density lipoprotein. METHODS:PubMed database was searched for relevant articles published from 1990 to 2015 using the keywords of“HDL and exercise, HDL and biological function”in English. Final y, 44 articles were included in result analysis. RESULTS AND CONCLUSION:The biological functions of high-density lipoprotein mainly include high-density lipoprotein-mediated metabolism of glucose, protein and fat, anti-inflammation, antioxidation and insulin secretion, and at the same time, we summarize the effects of exercise on the concentration, numbers of molecular and components of high-density lipoprotein. The results indicate that the combination of resistance and endurance training is the best way for raising the concentration and functional effects of high-density lipoprotein.

Objective To observe the effects of all-tram retinoic acid(ATRA)on intercellular communication function and connexin 43 expression in acute leukemia bone marrow stromal cells(ALBMSCs).Methods ALBMSCs were cultured in vitro,and the ATRA(1?10~(-5)mol/L)was added after serial subcultivation.The expression level of Cx43 was detected by immunochemistry and flow cytometry, and the gap junction intercellular communication(GJIC)was examined by using cell scarification with dye transfer(CSDT)technique.Re- sults Before and after addition of ATRA,the positive rates of Cx43 expression as detected by immunochemistry in ALBMSCs were(47.2?2.04)% and(54.5?5.86)%,respectively.The positive rates of Cx43 expression in ALBMSCs as detected by flow cytometry before and after the addition of ATRA were(38.75?23.95)% and(49.5?5.46)%,respectively.The expression of Cx43 in ALBMSCs after adding ATRA was significantly higher than that before the addition of ATRA(P

Objective: To define the occurrence rate, time course, and potential mechanism of hyponatremia in patients after Frankel Class-A acute cervical spinal cord injury. Methods: Analysis of data obtained from a retrospective review of blood and urine records of 35 hospitalized cases from 1992 to 1998. Results: Patients were admitted after (2.8±1.8) days postinjury and had been hospitalized for (52±13) days. Hyponatremia, the occurrence rate of which was 100%, developed at a mean time of (4.5±1.2) days postinjury, reached its nadir at the end of (14±3) days and recovered to normal at (39±10) days. Fifteen (42.88%) cases did not recover from hyponatremia in the hospitalized period. Patients were suffering from hypercapnia, hypernitremia, polyuria, and hyper-natriuresis besides kalemia. Conclusion: Severe and obstinate hyponatremia is a very common complication of cervical spinal cord injury. The mechanism may be related to the Cerebral Salt Wasting Syndrome.

Objective To investigate the relationship between the maturity and function of dendritic cells (DC) and hepatitis B virus covalently closed circular DNA (HBV cccDNA) load in the peripheral blood mononuclear cells (PBMC)/monocyte-derived DC in patients with chronic hepatitis B (CHB). Methods The peripheral blood samples were collected from 29 patients with CHB and 10healthy controls. PBMC were isolated freshly and induced with granulocyte/macrophage colony stimulating factor (GM-CSF) and interleukin-4 (IL-4). A large amount of DC were harvested after seven days of culture. The expressions of CD209, CD80, CD86, human leucocyte antigen (HLA)-DR and CD1a of DC were analyzed by flow cytometry. The HBV cccDNA load in PBMC and DC were measured by real-time polymerase chain reaction (PCR). The interleukin-12 (IL-12) level in the culture supernatant of DC was determined by enzyme linked immunosorbent assay (ELISA). The effects on T lymphocyte proliferation induced by DC were tested by mixed lymphocyte reaction (MLR). The data was compared by t test and analysis of variance. Results HBV cccDNA could be detected in PBMC from 16 patients, but not in DC from all 29 patients. HBV cccDNA load was all negatively correlated with the expressions of CD209 (r= -0. 793, P＜0.01), CD80 (r= -0. 581,P＜0.05), CD86 (r=-0. 698, P＜0.01), HLA-DR (r=-0. 817, P＜0.01), CD1a (r=-0. 734, P＜0.01), IL-12 level (r=-0. 632, P＜0.05) and allogenic T lymphocyte proliferation induced by DC (r=-0. 617, P＜0.05). The expressions of CD209, CD80, CD86, CD1a and HLA-DR on DC,IL-12 level in culture supernatant of DC and the allogenic T lymphocyte proliferation induced by DC in patients with positive PBMC HBV cccDNA were all significantly lower compared to those in healthy controls, and the changes of the parameters mentioned above were greater in PBMC HBV cccDNA positive patients than those in PBMC HBV cccDNA negative patients (P ＜ 0. 05 or P ＜ 0. 01).Conclusions The function and maturity of DC are impaired in CHB patients. HBV cccDNA can be detected in PBMC from CHB patients. Moreover, the higher PBMC HBV cccDNA is, the worse DC function and maturity are, which could be one of the important mechanisms of HBV persistent infection.

Objective To study the association of peptidylarginine deiminase 4 (PADI4) (padi4_94 and padi4_104) genetic single nucleotide polymorphism (SNP) and rheumatoid arthritis (RA) susceptibility in Han population of Hebei province. Methods This hospital-based case-control study included 115 RA patients and 106 healthy controls. All the individuals were recruited from Han Hebei residents and were randomly selected. The genotype and allele frequencies of PADI4 gene polymorphisms (padi4_94 and padi4_104) were analyzed by PCR-DNA sequencing method. Results The distribution of padi4_94 and padi4_104 genotypes between the two groups was not significantly deviated from that expected by Hardy-Weinberg equilibrium (P>0.05). The combined effect of padi4_94 and padi4_104 SNPs was analyzed and three haplotypos (AA, AG and GG) were found but without GA haplotype. The genotype and allele distribution of padi4_94 and padi4_104 in the patients with RA was not significantly different from that in healthy controls,and the analysis of haplotypes revealed that no haplotypes were risk factors for RA. Conclusion In Han population of Hebei province, the SNPs of PADI4 (padi4_94 or/and padi4_104) is no associated with RA susceptibility. Therefore, it should not be regarded as a genetic risk factor for RA.

Objective To provide a scientific basis for prevention of Keshan disease by observing the changes of electrocardiogram in residents from Keshan disease area and urban residents in Ju County.Method In 2013,four countries (towns) of Sangyuan,Anzhuang,Qishan and Longshan were selected as the investigation sites across the Keshan disease areas in Ju County of Shandong Province,one village was selected in each country (town),no less than 200 people were chosen from each village.There were 36 residential communities in urban area in Ju County,one residential community was selected from 4 positions (east,west,south and north) in urban area,no less than 200 non-endemic urban residents were chosen from each residential community as control,the electrocardiogram examination was conducted.According to the Keshan Disease Diagnostic Standard (WS/T 210-2011),Keshan disease was diagnosed.Results Among the 964 inhabitants investigated in Keshan disease area,143 cases showed abnormal electrocardiogram and the detection rate was 14.83％;in the 926 cases of urban electrocardiogram,78 cases showed abnormal electrocardiogram,abnormal rate was 8.42％,the difference was statistically significant (x2 =18.80,P ＜ 0.01).There were 93 cases who met the 8 Keshan disease diagnostic criteria of abnormal electrocardiogram changes in the Keshan disease areas,abnormal rate was 9.65％;while there were 37 cases in urban residents,abnormal rate was 4.00％,the difference was statistically significant (x2 =23.55,P ＜ 0.01).Conclusion These residents who have lived in Keshan disease endemic areas have a higher rate of abnormal electrocardiogram in Ju County of Shandong Province,they are still threatened by the causative factors of Keshan disease,and the authority should strengthen the prevention measures of Keshan disease.
