Objective:To compare the clinical efficacy of robot-assisted percutaneous screw implantation and free-hand open screw implantation by Wiltse approach in the treatment of thoracolumbar fracture.Methods:A retrospective cohort study was performed to analyze the clinical data of 71 patients with thoracolumbar fracture admitted to Second Affiliated Hospital of Soochow University from May 2018 to May 2020. There were 52 males and 19 females, with age range of 22-54 years[(41.0±7.8)years]. Of all, 33 patients were treated with robot-assisted percutaneous screw implantation (Group A) and 38 patients were treated with free-hand open screw implantation by Wiltse approach (Group B). Following parameters were measured, including frequency of radiation exposure, operation time, intraoperative blood loss, length of hospital stay, incidence of complications, rate of fracture healing at 3 months and 6 months postoperatively, visual analogue scale (VAS) and Oswestry dysfunction index (ODI) at 3 days, 3 months, 6 months postoperatively and at the last follow-up, anterior vertebral body height ratio and sagittal Cobb angle preoperatively, at 3 days postoperatively and at the last follow-up, and rate of screw implantation of grade A and B and rate of facet joint violation at 3 days postoperatively.Results:All patients were followed up for 10-24 months[(15.2±4.4)months]. Frequency of radiation exposure and operation time showed no statistical differences between the two groups (both P>0.05). Intraoperative blood loss was 100(100, 135)ml in Group A, less than 160(120, 200)ml in Group B ( P<0.01). Length of hospital stay was 8(7, 11) days in Group A, shorter than 12(10, 16)days in Group B ( P<0.01). There were no complications such as infection, spinal nerve injury or cerebrospinal fluid leakage in both group. There were no significant differences between the two groups in the rate of fracture healing at 3 and 6 months postoperatively (all P>0.05). VAS and ODI in Group A was 3(2, 4)points and 21(18, 23)points at 3 days postoperatively, lower than 4 (3, 5)points and 27(20, 32)points in Group B ( P<0.05 or 0.01), and the two groups showed no significant differences in VAS and ODI at other time points (all P>0.05). There were no significant difference in the anterior vertebral body height ratio or sagittal Cobb angle between the two groups at 3 days postoperatively and at the last follow-up (all P>0.05). Rate of screw implantation of grade A and B was 96.5% (191/198) in Group A, higher than 90.4% (206/228) in Group B ( P<0.05). Rate of facet joint violation was 4.0%(8/198) in Group A, lower than 11.8% (27/228) in Group B ( P<0.01). Conclusion:For thoracolumbar fracture, robot-assisted percutaneous screw implantation is superior to free-hand open screw implantation by Wiltse approach in terms of less bleeding, shorter hospitalization, earlier pain alleviation, higher accuracy of screw implantation and lower risk of facet joint violation.

OBJECTIVE:
To investigate the expression of CD47 molecules in patients with newly diagnosis of adult acute myeloid leukemia (AML) and its correlation with clinical prognosis.
METHODS:
20 patients with acute myeloid leukemia diagnosed in Shanghai Fengxian District Central hospital from April 2020 to October 2021 and 5 cases with non malignant hematological diseases in the control group were collected, and the expression of CD47 in single nuclear cells of bone marrow and peripheral blood was detected by real-time fluorescence quantitative polymerase chain reaction (qPCR). Combined with the blood image, bone marrow smears, flow cytometry, chromosome and gene detection, ECOG score, etc. during the patient's initial diagnosis, the relationship between the patient's prognosis and CD47 was evaluated.
RESULTS:
The expression of CD47 in bone marrow (P=0.0115) and peripheral blood mononuclear cells (P=0.0069) in new diagnosis AML patients was significantly higher than that of controls. In bone marrow mononuclear cells, the total survival time of patients with high CD47 expression was less than that of CD47 low expression patients (P=0.036). There was statistical significance in difference stratification group (P=0.012), but there was no statistical significance between CD47 expression and survival time in peripheral blood mononuclear cells (P=0.116). There were no statistical significance between bone marrow mononuclear cell CD47 expression and gene mutation fusion genes related to leukemia , CD34+, CD38+, CD123+ (P>0.05). The proportion of bone marrow protocells in AML patients was >50%, the ECOG score was >2 points, MLLELL fusion gene and chromosome prognosis stratification were all risk factors affecting the survival of patients (P=0023, 0.036, 0.012, 0.001, respectively). The high expression of bone marrow CD47 in AML patients indicated a high risk of recurrence (P=0.017).
CONCLUSION
The high expression of bone marrow mononuclear cell CD47 in AML patients indicates poorer survival and higher risk of recurrence.

Shenling Baizhusan is a traditional Chinese medicine compound prescription formulated on the basis of Si Junzitang (Ginseng Radix et Rhizoma, Atractylodis Macrocephalae Rhizoma, Poria, Glycyrrhizae Radix et Rhizoma). It has excellent functions of replenishing Qi, invigorating spleen, draining dampness, and checking diarrhea, and is one of the classical prescriptions of ''reinforcing earth to generate metal''. This prescription is primarily used in clinical practice to treat malnutrition in children, chronic diarrhea, gastrointestinal dysfunction, and other disorders. In addition, it has a good effect on gastrointestinal adverse reactions associated with radiotherapy and chemotherapy. With the booming of molecular biology, researchers have revealed the role of Shenling Baizhusan in the treatment of diseases, especially the mechanism of regulating different signaling pathways. We retrieved 26 relevant papers (4 written in English and 22 in Chinese) published in recent 5 years from 6 databases including China National Knowledge Infrastructure (CNKI), Wanfang Data, VIP, PubMed, Cochrance Library, and Excerpta Medica Database (Embase). On the basis of these papers, we summarized the mechanisms of Shenling Baizhusan in disease treatment. In the animal model of inflammatory bowel disease, Shenling Baizhusan can protect gastrointestinal mucosa by regulating the activation of nuclear factor kappa-B (NF-κB), mitogen-activated protein kinase (MAPK), Janus kinase/signal transducer and activator of transcription (JAK/STAT), and myosin light chain kinase-myosin light chain (MLCK-MLC) signaling pathways. In the animal model of non-alcoholic fatty liver disease, Shenling Baizhusan regulates the activation of phosphoinositide 3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/Akt/mTOR) signaling pathway and Kelch-like ECH-associating protein 1/NF-E2-related factor 2/advanced glycation end-products (KEAP1/NRF2/AREs) signaling pathway, thus alleviating the lipid metabolism disorder induced by high-fat diet and reducing liver lipid accumulation and inflammatory response. In the animal model of lung cancer with bone metastasis, Shenling Baizhusan regulates the activation of PI3K/Akt/mTOR signaling pathway, thus playing an analgesic role. By summarizing the mechanisms of Shenling Baizhusan in treatment of different disease models from signaling pathways, we aim to provide clues for the in-depth study of this prescription.
