ABSTRACT
The study utilized a cross-sectional design. Data was retrieved from the American Academy of Family Physicians fellowship training directory, including program names, areas of focus, program length, and program descriptions. The collected data was categorized and analyzed based on areas of focus and training duration. The program descriptions were also analyzed qualitatively using Nvivo12 software. A total of 532 programs were included in the study:295 programs (55.5%) were ACGME-certified, while 237 programs (44.5%) were not. The majority of programs, 468 (87.9%), were clinically oriented, while 64 programs (12.1%) were non-clinical. Among ACGME-certified programs, the largest number of programs were in sports medicine (121 programs), followed by geriatrics (52 programs). Among non-certified programs, the largest number of programs was in obstetrics (66 programs), accounting for 27.8% of all non-certified programs. Qualitative research found that fellowship programs were diverse, reflecting the societal demands of healthcare service. Moreover, a significant emphasis was placed on empowering teaching and research abilities.The family medicine fellowship programs in the United States cover a wide range of disciplines and meet both the professional interests of doctors and the needs of patients. As China continues to implement its tiered medical system, it can learn from the experience of the United States and develop general practice subspecialty training programs, thereby improving the service capacity of general practitioners and improve the quality of healthcare.
ABSTRACT
Objective:To explore the teaching effect of organ system based integrated curriculum in the undergraduates of clinical medicine.Methods:A retrospective cohort study was conducted among 284 undergraduates majoring in clinical medicine from Batch 2011 to Batch 2016 in Shanghai Jiao Tong University School of Medicine.

Conclusion:The teaching of organ system based integrated curriculum can improve students' comprehensive abilities, and has certain requirements for students' learning autonomy.
ABSTRACT
Objective:To explore the method and effect of aesthetic reconstruction of distal segment of finger with modified second toe nail flap while retains the full length of the second toe.Methods:From April 2018 to June 2020, 16 patients with degloving injury of distal segment of fingers were treated. The patients were 11 males and 5 females aged 18 to 45 years in an average of 29 years. All injuries were degloving injury of the distal segment of finger, including 5 index fingers, 7 middle fingers, 3 ring fingers and 1 little finger. The time from injury to operation was 0.5-3.0 hours, with an average of 1.5 hours. The second toe nail flap was used for the reconstruction. After the dorsal flap of the second toe was rotated to the plantar side of the foot, the donor site defect was repaired by a skin graft. The regular follow up reviews were carried out.Results:All 16 flaps survived except 1 flap had necrosis and underwent toe amputation of the distal segment of the second toe. All patients entered follow-up for 4-12 months, with an average of 5.7 months. The blood supply of all flaps was good. After the flaps having atrophied, they were equivalent to the diameter of the body of normal fingers with the TPD at 6.5(4-10) mm; All patients returned to work. According to the Evaluation Standard of Upper Limb Function of Chinese Hand Surgery Society, 13 cases were graded as excellent, 2 were good and 1 was fair.Conclusion:The techniques of modified second toe toenail flap in aesthetic reconstruction of the distal segment of a finger can effectively restore the length and aesthetic appearance of the affected finger, without sacrificing the donor toe. Clinical application of it should be promoted.
ABSTRACT
Objective To investigate the effect of calcitriol on osteogenic differentiation of mesenchymal stem cells (MSCs) induced by bone morphogenetic protein 9 (BMP9). Methods The experiment was divided into four groups: control group, calcitriol group, BMP9 group and BMP9+calcitriol group. Quantitative PNPP method was used to detect alkaline phosphatase (ALP) activity. RT-PCR and Western blotting method analyzed expression of osteocalcin(OCN)and osteopontin (OPN). Alizarin red staining assessed the formation of mineralized nodules. In addition, the changes of cell morphology and elastic modulus during osteogenic differentiation were studied by atomic force microscope. ResultsCompared with control group, calcitriol alone had no significant effect on the osteogenic differentiation of MSCs, but calcitriol could enhanced expression of osteogenic markers and formation of mineralized nodules induced by BMP9. However, neither calcitriol nor BMP9 could affect elastic modulus of cells. The combined treatment of BMP9 and calcitol could enhance phosphorylation of AKT and β-catenin which were both important for osteogenesis. The pretreated PI3K inhibitor could inhibit phosphorylation of AKT and β-catenin as well as ALP activity in BMP9+calcitriol group. In addition, calcitriol did not affect the BMP/Smad signaling pathway induced by BMP9. Conclusions Calcitriol synergies with BMP9 could promote MSCs osteogenesis by activating the PI3K/AKT signaling pathway. The study about effects and mechanisms of different regulatory factors on osteogenic differentiation of MSCs is of great significance for the treatment of osteoporosis and the development of bone tissue engineering.

ABSTRACT
Osteogenic differentiation of mesenchymal stem cells (MSCs) is an important link of bone metabolism and bone repair, the mechanism of which is usually complicated. Recent studies have found that BMP, FGF, Wnt, Hedgehog, NELL1, IGF, Notch and othersignaling molecules are involved in the regulation of osteogenic differentiation of MSCs. These signaling molecules themselves have been shown to have a strong ability to promote osteogenic differentiation. They can activate the corresponding receptors by specific ligands, thus initiating the specific signal transduction pathways in the cell, and finally promote the transcription and translation of the genes related to bone formation. Furthermore, all the signaling pathways form a complex network which regulates and influences the osteogenic differentiation ofMSCs. Further researches on the mechanism of the interaction of these signaling pathways is of great significance in promoting the development of bone tissue engineering and the treatment of bone metabolic diseases.

ABSTRACT
Objective To evaluate the association between serum 25-hydroxyvitamin D3 [25 (OH)D3] and arterial stiffness in patients with chronic kidney disease (CKD).Methods Three hundred patients with CKD were included,and were divided into two groups based on serum 25(OH)D3 levels:vitamin D deficient [25(OH)D3 < 20 μg/L] and vitamin D non-deficient [25(OH)D3≥20 μg/L].Brachial ankle pulse wave velocity (baPWV),which reflected arterial stiffness,was calculated using the single-point method.Clinical data were collected in details.Correlation between serum 25(OH)D3 level and baPWV was assessed by the single factor correlation test and multiple linear regression analysis.Results The prevalence of vitamin D deficiency was 62.7%(188/300).The concentration of 25(OH)D3 was (17.62±8.54) μg/L in total patients,but was (12.38±4.55) μg/L and (26.44±6.05) μg/L in the subgroups of vitamin D deficient and non-deficient,respectively(P < 0.01).There was a higher value of baPWV in the group of vitamin D deficient than that of vitamin D non-deficient (1 827.34±429.11 vs 1 555.31 ±353.14,P < 0.01).Serum 25(OH)D3 level and baPWV was negatively correlated in total patients(r=-0.38,P < 0.01) and each stage of CKD(stage 2-5)[r=-0.30,P < 0.05; r=-0.26,P < 0.05; r=-0.46,P < 0.01; r=-0.57,P < 0.01].Multiple linear regression analysis showed that vitamin D level was independently associated with baPWV(Model 1:β=-0.18,P < 0.01; Model 2:β=-0.17,P=0.01).Both models accounted for 50% (R2=0.50) of total variance of baPWV.Conclusions Vitamin D deficiency is common in CKD,and a low 25(OH)D3 level is significantly associated with increased arterial stiffness in these patients.Clinical intervention studies are needed to clarify whether treatment with vitamin D decreases the risk of cardiovascular disease in patients with CKD.

ABSTRACT
This study aimed to examine whether ophiopogonin D (OP-D) is capable of protecting cardiomyocytes against DOX-induced injury and the mechanisms involved. H9c2 cells were cultured. MTT assay was used to evaluate cell viability and toxicity. Mito-tracker as fluorescence probe was used to measure ROS content raised from mitochondria. The mRNA and protein expression of ATF6alpha, GRP78 and CHOP were analyzed using real-time PCR and Western blotting, respectively. The results showed that a significant endoplasmic reticulum stress (ERS) was induced upon exposure of H9c2 cells to DOX as indicated by the increase in the expression of ERS related proteins, which was paralleled with the accumulation of reactive oxygen species (ROS) and decrease in the viability of H9c2 cells. Whereas, DOX-induced ROS accumulation and up-regulation of ERS related proteins were partially abolished by pretreatment with OP-D. Consequently, a DOX-induced ERS was mitigated by application of OP-D. Similarly, DOX-induced decrease in cell viability was partially attenuated by either inhibiting CHOP or pretreatment with N-acetylcysteine (NAC), an antioxidant. Moreover, cardiac ultrastructural abnormalities seen in mouse receiving DOX injections were obviously ameliorated by pretreatment of OP-D. Taken together, the present study proved that OP-D protects cardiomyocytes against DOX-induced injury, at least in part, through reducing ROS accumulation and alleviating ERS.
