Serotonin-selective reuptake inhibitors （SSRIs）， as widely used antidepressants in clinical practice， exhibit significant individual differences in antidepressant efficacy. Gut microbiota plays an important role in the development and progression of depression， and the use of SSRIs exerts a significant impact on the gut microbiota of patients with depression. Based on this， this article reviews the research progress on the interactions between the antidepressant effects of SSRIs and gut microbiota. It has been found that SSRIs can influence the diversity， abundance， and function of the gut microbiota directly or indirectly. Conversely， the composition of the gut microbiota and differences in its functional metabolic pathways， and other factors， can in turn affect the antidepressant effects of SSRIs. Therefore， in clinical practice， gut microbiota diversity can be utilized as a predictive indicator for the antidepressant effects of SSRIs. Probiotics can be employed as an adjunct therapy alongside SSRIs， and dietary adjustments， as well as fecal microbiota transplantation， can be used to enhance the therapeutic efficacy of SSRIs. In the future， large-scale， multicenter clinical studies should be conducted， enrolling a broadly representative cohort of patients with depression， to uncover the true association between the antidepressant effects of SSRIs and gut microbiota， thereby opening up more effective avenues for the comprehensive treatment of depression.

Hexokinase(HK),as the first rate-limiting enzyme for glycolysis,promotes tumor progression by improving levels of aerobic glycolysis in tumor cells.By binding to the voltage-dependent anion channel(VDAC)on the outer mitochondrial membrane,HK2 is involved in increasing the stability of mitochondrial membranes,thereby inhibiting apoptosis of tumor cells and promoting tumor survival,which is why HK2 may be one of the factors that promote tumor resistance to chemotherapy drugs.This article reviews the research progress in the role of HK2 in tumor glucose metabolism,mitochondrial apoptosis and drug resistance.

Objective:To analyze the risk factors of radiation-based sarcopenia in patients with multiple myeloma (MM).Methods:A total of 185 clinical and imaging data of patients with MM admitted to Beijing Chaoyang Hospital from September 2009 to October 2019 were retrospectively analyzed. The area of the erector spinae muscle and the area of fatty infiltration (FI) in the fascial compartment were measured by Image-pro Ρlus software, and the area of the fat-free erector spinae muscle and the fat infiltration rate (FI%) were calculated. Sarcopenia was defined as an erector spinae area of less than 3 197 mm 2 in males and 2 895 mm 2 in females. The differences in gender, age, body mass index, disease duration, hemoglobin, leukocytes, platelets, albumin, serum calcium, lactate dehydrogenase, serum creatinine, alkaline phosphatase, M-protein, serum β 2-microglobulin, bortezomib chemotherapy, receipt of stem cell transplantation, osteopathy, stage, recurrence and progression of MM between the sarcopenia group and the normal muscle group were compared. Binary logistic regression was used to analyze the independent risk factors of sarcopenia in MM patients. Kaplan-Meier curves were drawn to compare the survival rates between the two groups. Results:53.0% (98/185) of MM patients were complicated with sarcopenia: there were 30 males, whose fat-free erector spinae area was 25.0±6.0 cm 2, the FI of erector spinae was 12.0±4.8 cm 2, and the FI% was 31.5%±12.0%, while there were 68 females, whose fat-free erector spinae area was 22.7±4.2 cm 2, the FI of erector spinae was 10.7±4.1 cm 2, and the FI% was 30.2%±9.8%. 47.0% (87/185) of MM patients had normal muscle mass: there were 62 males, whose fat-free erector spinae area was 40.6±6.5 cm 2, the FI of erector spinae was 9.3±4.8 cm 2, and the FI% was 17.9%±7.4%, while there were 25 females, whose fat-free erector spinae area was 33.6±5.1 cm 2, the FI of erector spinae was 9.9±3.0 cm 2, and the FI% was 21.9%±5.7%. There were statistically significant differences in the gender composition ratio (χ 2=30.47, P<0.001), hemoglobin ( t=-2.73, P=0.007), serum creatinine ( Z=-2.26, P=0.024), receipt of stem cell transplantation (χ 2=4.32, P=0.038), and MM recurrence and progression (χ 2=3.85, P=0.050) between the two groups. However, there were no significant differences in age, body mass index, course of disease, leukocytes, platelets, albumin, alkaline phosphatase, lactate dehydrogenase, serum calcium, M-protein, serum β 2-microglobulin, bortezomib chemotherapy, osteopathy or MM stage ( P>0.05). Binary logistic regression analysis showed that female was an independent risk factor for sarcopenia in MM patients. The survival rates at 2, 3, 4, and 5 years were 87.9%, 71.8%, 64.4%, and 53.7% in the sarcopenia group, and 92.1%, 75.8%, 66.8%, and 66.8% in the normal muscle group, respectively, with no statistically significant differences ( HR=0.71, P=0.364). Conclusion:The incidence of radiation-based sarcopenia in MM patients is 53.0%. Low hemoglobin and blood creatinine levels, not receiving stem cell transplantation, and recurrence or progression of MM are associated with sarcopenia in MM patients, and female is an independent risk factor for sarcopenia in MM patients.

Mammals exhibit limited heart regeneration ability, which can lead to heart failure after myocardial infarction. In contrast, zebrafish exhibit remarkable cardiac regeneration capacity. Several cell types and signaling pathways have been reported to participate in this process. However, a comprehensive analysis of how different cells and signals interact and coordinate to regulate cardiac regeneration is unavailable. We collected major cardiac cell types from zebrafish and performed high-precision single-cell transcriptome analyses during both development and post-injury regeneration. We revealed the cellular heterogeneity as well as the molecular progress of cardiomyocytes during these processes, and identified a subtype of atrial cardiomyocyte exhibiting a stem-like state which may transdifferentiate into ventricular cardiomyocytes during regeneration. Furthermore, we identified a regeneration-induced cell (RIC) population in the epicardium-derived cells (EPDC), and demonstrated Angiopoietin 4 (Angpt4) as a specific regulator of heart regeneration. angpt4 expression is specifically and transiently activated in RIC, which initiates a signaling cascade from EPDC to endocardium through the Tie2-MAPK pathway, and further induces activation of cathepsin K in cardiomyocytes through RA signaling. Loss of angpt4 leads to defects in scar tissue resolution and cardiomyocyte proliferation, while overexpression of angpt4 accelerates regeneration. Furthermore, we found that ANGPT4 could enhance proliferation of neonatal rat cardiomyocytes, and promote cardiac repair in mice after myocardial infarction, indicating that the function of Angpt4 is conserved in mammals. Our study provides a mechanistic understanding of heart regeneration at single-cell precision, identifies Angpt4 as a key regulator of cardiomyocyte proliferation and regeneration, and offers a novel therapeutic target for improved recovery after human heart injuries.

Objective:To summarise the experience in use of sural neurouascular flap in repair of the soft tissue defects of foot and ankle, and explore the methods in promoting the survival and appearance of the flap.Methods:Data of 10 patients who underwent sural neurocutaneous flap surgery for repairing soft tissue defects in the foot and ankle in the Department of Foot and Ankle of Xuzhou Renci Hospital from October 2019 to June 2020 were retrospectively analysed. Among the 10 patients, 8 were males and 2 were females, and the age ranged from 18 to 54 years old, with an average age of 42.5 years old; Causes of injury: 8 patients injured by traffic accident and 2 by incision necrosis after calcaneal fracture operation. The areas of soft tissue defect were 4.0 cm×6.0 cm-16.0 cm×10.0 cm. Sural neurouascular flap was used for the defect repairs. Method of optimisation: ①The small saphenous vein in the flap was separated and retained in the limb to optimise the venous circulation. ②Freed peroneal perforator vessels that entered the pedicle, and made the point where the vessels entering the pedicle as the rotation point. The pedicle contained the sural neurovascular bundle, the main trunk of the small saphenous vein and the fascia tissue, with a width about 2.0 cm. It not only increased the blood supply of the flaps, but also a good appearance of the pedicle. ③ The torsion of the pedicle was covered by an arc-shaped flap and transferred through an open channel to prevent compression. ④The donor site was covered with relay flap. According to the location of the donor site, a proximal peroneal artery perforator flap or medial and lateral sural artery perforator flap was selected. ⑤Sural nerve was anastomosed with the peripheral sensory nerve in some cases. The survival of the flap, Maryland Foot Function Score and British Medical Research Council (BMRC) sensory function evaluation were investigated in the follow-up to evaluate the functional recovery of the flap and limb.Results:All the 10 patients received the follow-up for 6 to 12 months, with an average of 8.5 months. The donor and recipient flaps survived completely with good appearance in lower limb, good soft texture, good elasticity and wear resistance. The sensation of the flap with nerve anastomosis in 3 cases was evaluated according to BMRC, and they achieved sensation recovery up to level of S 3 or above. The patients had great satisfactions. At the last follow-up, the curative efficacy was evaluated according to the Maryland scoring system. It ranged from 85 to 98 points, with an average of 91.6 point, 8 patients in excellent and 2 in good. Conclusion:Sural neurouascular flap can achieve a sufficient blood supply, a reasonable venous circulation and a high survival rate. The donor site was covered with relay flap to obtain a good appearance, and the anastomosed sensory nerve offered a good sensation. The function of foot and ankle recovered well, and the clinical effect was satisfactory.

Objective:To evaluate the efficacy of holographic image technology in robot-assisted laparoscopic radical prostatectomy (RARP).Methods:The clinical data of 34 patients with prostate cancer who underwent RARP in our hospital during October 2020 and December 2020 was analyzed retrospectively. The average age of the patients was 67.8 (52-78) years. The mean BMI was 25.8 (18.0-32.3) kg/m 2. The median level of PSA before surgery was 13.4 (2-149) ng/ml. Median prostate volume was 31.7 (9.5-159.1) ml. EAU risk groups for biochemical recurrence of localised and locally advanced prostate cancer were list as below: 5 cases of low-risk, 7 cases of medium-risk, 22 cases of high-risk. There were 9, 16, 9 cases with the ASA score of 1, 2, 3 point, respectively. Preoperative Gleason score of 34 patients were list as below: 9 cases in score ≤6 group, 15 cases in score=7 group, 10 cases in score ≥8 group. For clinical stage before the surgery, 13 cases ≤T 2a stage, 1 case in T 2b stage, 20 cases ≥T 2c stage. The engineers established holographic images of 34 patients based on multiparametric magnetic resonance imaging (mpMRI) and the reports before the operation. Surgeons can obtain the size and location of tumors, surrounding neurovascular bundles visually by revolving, assembling, disassembling and concealing images, which was helpful for pre-surgery planning. By manipulating the holographic images extracorporeally, surgeons can discriminate Internal sphincter of urinary bladder and vesicoprostatic muscle, neurovascular bundles, membranous part, seminal vesicle easily, which improves the operation accuracy. Results:All 34 cases underwent operation successfully without transferring to open surgery. The median operative time was 157.5 (95-276) min with an estimated blood loss of 50 (20-300) ml. The median drainage removal time was 2 d and median hospitalization time was 3.5 d, respectively. The catheters were removed within an average time of 20.5 d. For postoperative Gleason score, there were 2 cases in score ≤6 group, 16 cases in score =7 group, 8 cases in score ≥8 group and 8 cases can’t make a score. For clinical stage after the surgery, 10 cases were ≤T 2a stage, 1 case was T 2b stage, 23 cases were ≥cT 2c stage. 22 cases underwent pelvic lymph node dissection, including a patient with right iliac fossa lymph node metastasis. There were 2 cases with positive surgical margin and 3 cases with Clavien-DindoⅠcomplications. The rate of 1-month and 3-month urinary continence were 47.1% and79.4%, respectively, 8 cases recovered erectile function after 3 month. Conclusions:Holographic image technology can promote cancer dissection completely, achieve urinary continence early and reduce perioperative complications tremendously. The technology is the "intraoperative security" for the accurate surgical treatment of prostate cancer.

Objective To evaluate the value of stroke prognostication using age and National Institute of Health Stroke Scale index (SPAN) for outcome after early endovascular treatment for anterior circulation large vessel occlusion.Methods The patients who underwent early endovascular treatment were prospectively,sequentially collected in Yijishan Hospital of Wannan Medical College from December 2014 to September 2017 and Jinling Hospital from March 2014 to March 2017.Individuals whose age in years plus NIHSS score was greater than or equal to 100 were designated as SPAN-100-positive patients,while those with a score less than 100 were designated as SPAN-100-negative patients.We compared the baseline data and perioperative data between the two groups.The 90 days modified Rankin Scale score≤2 was regarded as favorable outcome.Single factor and multivariable Logistic regression analyses were used to determine the association between SPAN-100 and outcomes.Results One hundred and ninety patients were enrolled,20 (10.5％) of which were SPAN-100 positive,and 170(89.5％) were SPAN-100 negative.There were no significant differences between the two groups on postoperative intracerebral hemorrhage and 90 days mortality.Ninety days independence rates were higher in SPAN-100-negative patients (77/170,45.3％) than in SPAN-100 positive patients (4/20,20.0％;x2 =4.681,P =0.030).Multi-factor Logistic regression analysis showed that the higher preoperation systolic pressure (OR =1.030,95％ CI 1.008-1.052,P =0.007),the lower Alberta Stroke Program Early CT Score (OR =1.609,95％ CI 1.056-2.453,P =0.027) and poor collateral circulation(OR =5.714,95％ CI 1.668-19.570,P =0.006) were the independent risk factors of outcomes.Conclusion SPAN-100 is not an independent predictor of favorable outcome after adjusting for factors of outcomes in patients with anterior circulation large vessel occlusion.

Objective To evaluate the effects of the modified needle filtration on bone marrow collection. Methods The original needle filtration was modified and upgraded. Totally 80 bone marrow donors whose bone marrow was collected using the original needle filtration were randomly selected and divided into the control group, while another 80 bone marrow donors whose bone marrow was collected using the modified needle filtration were randomly selected and divided into the modified group. Anesthesia time, time of bone marrow collection, number of 20 ml injectors used and number of nursing staff were compared between the two groups. Results The anesthesia time of the control group was (112.30±23.87) min, while that of the modified group was (100.50±25.68) min (t=3.027, P＜0.01). The time of bone marrow collection of the control group was 52.00 (41.25, 60.75) min, whereas that of the modified group was 39.00(31.25, 53.00) min (U=-3.879, P＜0.01). The number of 20 ml injectors used in the control group was 121(103, 145), while that in the modified group was 80(50, 100) (U=-7.101, P＜0.01). Two nurses were required in the control group, whereas only 1 nurse was needed for bone marrow collection in the modified group. Conclusions The modified needle filtration, when used in bone marrow collection, can shorten the anesthesia time and the time of bone marrow collection, save sterile materials and nursing staff, reduce the wastage of bone marrow blood, and lessen pricking wound.
