ABSTRACT
With rapid development of organ transplantation, the issue of global organ shortage has become increasingly prominent. At present, liver transplantation is the most effective treatment for end-stage liver disease. Nevertheless, the shortage of donors has been a key problem restricting the development of liver transplantation. China is a country with a larger number of hepatitis B, and the shortage of donor liver is particularly significant. Many critically ill patients often lose the best opportunity or even die because they cannot obtain a matched donor liver in time. As a strategy to expand the donor pool, ABO-incompatible (ABOi) liver transplantation offers new options for patients who are waiting for matched donors. However, ABOi liver transplantation is highly controversial due to higher risk of complications, such as severe infection, antibody-mediated rejection (AMR), biliary complications, thrombotic microangiopathy, and acute kidney injury, etc. In this article, research progress in preoperative, intraoperative and postoperative strategies of ABOi liver transplantation was reviewed, aiming to provide reference for clinical application and research of ABOi liver transplantation.
ABSTRACT
Objective:To comprehensively evaluate the tricuspid valve, right heart anatomical characteristics and related dynamic parameters in patients with different degrees of functional tricuspid regurgitation (FTR) using four-dimensional auto tricuspid valve quantitative(4D Auto TVQ), four-dimensional auto right ventricle quantitative(4D Auto RVQ), and four-dimensional auto left atrium quantitative(4D Auto LAQ), and to investigate the structural and functional changes of the tricuspid valve and right heart in them.Methods:Sixty-three patients with FTR diagnosed by echocardiography at the First Affiliated Hospital of Guangxi Medical University from February to July 2022 were prospectively selected as the case group, including 30 patients with mild FTR and 33 patients with moderate or above FTR, and 30 healthy subjects were selected as the control group. Transthoracic echocardiography was used for two-dimensional and three-dimensional image acquisition of the heart. The tricuspid regurgitation volume, left ventricular ejection fraction (LVEF), right ventricular global strain (RVGS) were measured by 2D images, and pulmonary artery systolic pressure (PASP) were measured from the tricuspid regurgitation pressure difference. The 3D images were imported into EchoPAC 204 to obtain the tricuspid valve, right heart structure and related dynamic parameters. The annulus area (AA), annulus perimeter(AP), spherical index (SI), annulus area change fraction (AC), coaptation point height (CPH), and tenting volume (TV) were measured by 4D Auto TVQ. The right atrial maximum volume (RAVmax) and right atrial minimum volume (RAVmin) were measured by 4D Auto LAQ. Right ventricular end-diastolic volume (RVEDV), right ventricular end-systolic volume (RVESV), right ventricular fractional area change (RVFAC) and tricuspid annular plane systolic excursion (TAPSE) were measured by 4D Auto RVQ. After standardizing the dimension parameters with body surface area (BSA), the differences in the above parameters were compared between the three groups, the correlation between regurgitant volume and each parameter was compared by correlation analysis, and the independent factors of increased tricuspid regurgitant volume were investigated by univariate and multivariate linear regression analysis.Results:There were statistically significant differences in PASP, AA/BSA, AP/BSA, AC, TV, RAVmax/BSA, RAVmin/BSA, RVFAC, RVGS, and TAPSE between the three groups (all P<0.05). There were statistically significant differences in LVEF, CPH, RVEDV/BSA, and RVESV/BSA in the moderate and above FTR group compared with the control and mild FTR groups (all P<0.05). Correlation analysis showed that RAVmin was the most highly correlated with tricuspid regurgitant volume ( r=0.875, P<0.001) and TV and end-systolic annulus area(ESAA) were highly correlated with tricuspid regurgitant volume ( r=0.747, 0.683; both P<0.001) in patients with FTR. Multifactorial linear regression showed that RAVmin, TV and regurgitant volume were independently positively correlated (β=0.721, 0.205; both P<0.05). Conclusions:The four quantification technique can provide valid structural and functional information by quantifying the tricuspid valve as well as the right heart in patients with FTR, and RAVmin and TV are independent correlates of increased tricuspid regurgitant volume.
ABSTRACT
ObjectiveTo explore the effect of anodal transcranial direct current stimulation (atDCS) on premotor cortex (PMC) on upper limb motor function in patients with severe stroke. MethodsFrom June, 2021 to December, 2022, 60 patients with severe stroke in Zhejiang Provincial People's Hospital were randomly divided into control group (n = 20), primary motor cortex (M1) group (n = 20) and PMC group (n = 20). All the groups accepted routine rehabilitation treatment, while the control group accepted atDCS pseudo stimulation to the focus side PMC, M1 group accepted atDCS to the focus side M1, and PMC group accepted atDCS to the focus side PMC, for six weeks. Fugl-Meyer Assessment-Upper Extremities (FMA-UE), Wolf Motor Function Test (WMFT), the surface electromyography root mean square (RMS) ratio of affected/unaffected side of triceps and extensor carpus were used to evaluate the efficacy before and after treatment. ResultsAfter treatment, the scores of FMA-UE and WMFT, and RMS ratio of triceps and extensor carpus significantly increased in all the groups (|t| > 2.458, P < 0.05), and were better in PMC group than in the other two groups (F > 4.084, P < 0.05). ConclusionatDCS on PMC could improve the overall function of upper limb in patients with severe stroke.
ABSTRACT
@#Objective To investigate the effect of intravenous analgesia with a wireless or traditional analgesia pump system in thoracoscopic lung resection. Methods Patients who used the patient-controlled intravenous analgesia after thoracoscopic lung resection between June 2016 and June 2021 were enrolled in the study. They were allocated into a wireless pump group (a ZigBee-based wireless analgesia pump system collecting data automatically) and a traditional analgesia pump group. Perioperative analgesia management followed the routine standard operation protocol of Shanghai Chest Hospital. The patients’ numeric rating scale (NRS) for pain and postoperative nausea and vomiting (PONV) scores were collected for analysis from the Anesthesia Information Record System. The incidence of postoperative analgesia insufficiency (defined as NRS≥4 points) within 48 h, the incidence of PONV within 24 h, and the 48 h completion rate of analgesia pump infusion were compared. Results A total of 59 431 patients were collected, including 24 855 males and 34 576 females, 17 209 patients in the wireless pump group, and 42 222 patients in the traditional analgesia pump group. The incidence of analgesia insufficiency within 48 h after operation (3.75% vs. 4.98%, P=0.007), the incidence of PONV within 24 h after operation (13.60% vs. 16.70%, P=0.030) in the wireless pump group were lower than those in the traditional analgesia pump group. The 48 h completion rate of analgesia pump infusion in the wireless pump group was higher than that in the traditional analgesia pump group (83.40% vs. 71.90%, P<0.001). The wireless pump group could monitor the pressing times and use of the analgesia pump, while the traditional analgesia pump group could not record the relevant data. Conclusion Compared with the traditional analgesia pump, the wireless analgesia management system may be convenient for timely, accurate and individualized management, and has good analgesic effect and low incidence of adverse reactions, and may be more suitable for perioperative analgesia management.
ABSTRACT
Objective:To explore the preventive effects of pancreatic duct stent combined with rectal administration of indomethacin suppository for post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP) after difficult bile duct intubation during endoscopic retrograde cholangiopancreatography (ERCP).Methods:From January 2019 to December 2021, patients with biliary and pancreatic diseases undergoing ERCP in Hangzhou Hospital Affiliated to Nanjing Medical University were given 100 mg indomethacin suppository to anal canal 30 minutes before the operation. And those with difficult bile duct intubation during the operation ( n=204) were included in this study. According to the random number table, they were divided into the combination group (implanted with pancreatic duct stent during the operation, n=104) and the indomethacin group (not implanted with stent, n=100). The incidences of hyperamylasemia and PEP were compared between the two groups. Results:The incidences of postoperative hyperamylasemia [21.2% (22/104) VS 34.0% (34/100), χ2=4.22, P=0.040] and PEP [14.4% (15/104) VS 32.0% (32/100), χ2=8.88, P=0.003] in the combination group were significantly lower than those in the indomethacin group. There was no significant difference in the incidence of severe PEP between the two groups [1.0% (1/104) VS 1.0% (1/100), χ2=0.001, P=0.978]. Conclusion:Compared with rectal administration of indomethacin suppository alone, the incidences of hyperamylasemia and PEP after difficult bile duct intubation during ERCP can be further reduced when it is combined with pancreatic duct stent placement.
ABSTRACT
Objective:To compare the efficacy and safety of endoscopic retrograde cholangiopancreatography (ERCP) assisted with colonoscope and enteroscope in patients with history of Roux-en-Y anastomosis.Methods:A retrospective study was performed on the data of 70 patients who underwent ERCP assisted with standard colonoscope or single balloon enteroscope after Roux-en-Y reconstruction in Hangzhou Hospital Affiliated to Nanjing Medical University from January 2017 to December 2020. Patients were divided into the standard colonoscopy group ( n=43) and the single balloon enteroscopy group ( n=27) according to endoscopy. The success rates of insertion, intubation and ERCP, and incidence of complications were compared. Results:A total of 81 ERCP procedures were performed in 70 patients. The insertion success rates of the standard colonoscopy group and the single balloon enteroscopy group were 91.8% (45/49) and 78.1% (25/32), respectively, showing no significant difference ( χ2=2.04, P=0.153). The success rates of primitive papilla intubation in the two groups were 74.1% (20/27) and 1/6, showing significant difference ( P=0.016). The ERCP success rates of the standard colonoscopy group and the single balloon enteroscopy group were 75.5% (37/49) and 59.4% (19/32), showing no significant difference ( χ2=2.36, P=0.124). The post operative complication incidences of the standard colonoscopy group and the single balloon enteroscopy group were 4.1% (2/49) and 9.4% (3/32), showing no significant difference ( χ2=0.25, P=0.620). Conclusion:ERCP assisted with standard colonoscope and single balloon enteroscope is safe and effective in patients after Roux-en-Y anastomosis. Standard colonoscopic ERCP can become an endoscopy solution for patients with biliary tract disease after Roux-en-Y reconstruction.
ABSTRACT
Objective:To investigate the feasibility and therapeutic effect of total knee arthroplasty (TKA) with cruciate-retaining (CR) prosthesis by using FEM-X1 femoral extramedullary positioning instrument based on the theory of restricted kinematic alignment (rKA).Methods:Thirty five cases who underwent total knee arthroplasty in Nanjing Drum Tower Hospital from November 2019 to December 2020 were retrospectively analyzed, including 7 males and 28 females with an average age of 71± 8 years (ranging from 55 to 85 years) Following the guidance of rKA alignment, the FEM-X1 femoral extramedullary positioning instrument was used for TKA with CR prosthesis. Before the operation, the full-length lower limb radiographs of both anteroposterior and lateral views were taken in a standing position for preoperative assessment of lateral distal femoral angle (LDFA), the medial proximal tibial angle (MPTA) and hip-knee-ankle angle (HKA). According to the principle of rKA alignment, the target LDFA, MPTA and HKA were calculated. The proximal end of tibia and distal end of femur were cut using extramedullary positioning instrument respectively. The posterior femoral condyle was cut according to the tibial plateau and mediolateral soft tissue tension. The prosthesis was installed after osteotomy. The release of collateral ligaments, PCL function, release of PCL, patellofemoral trajectory, release of patellofemoral support band, the amount of blood loss and time of operation were recorded. Postoperative LDFA, MPTA, HKA, and posterior slope angle of tibial prosthesis were measured on X-ray images. The Knee Society Score (KSS) was used for functional evaluation.Results:Thirty five cases of TKA with CR prosthesis following rKA alignment were successfully completed. The operation time was 100 (90, 110) min, and the blood loss was 100 (100, 200) ml. 30 of them were followed up for 12.5±0.7 months (ranging from 12 to 14 months). The pre-operative and post-operative LDFA were 1.0°(-2.0°, 4.0°), 0°(-2.0°, 2.0°), MPTA were -4.0°(-5.0°, -1.0°), -2.0°(-3.0°, -1.0°), HKA were -3.0°(-3.0°, -1.0°), -2.0°(-3.0°, -1.0°). There was no significant difference between the three angles before and after operation ( Z=-0.89, P=0.372; Z=1.87, P=0.061; Z=1.03, P=0.302). The average posterior tibial slope was 5°(3°, 7°). At the follow-up of one year, the KSS clinical score was 94(92, 97) and functional score was 80(70, 90) in 30 cases. During the operation, PCL was released in 1 case because of excessive tension; and lateral retinacular release was performed in 1 case because of poor patellofemoral track. Conclusion:ITKA with CR prosthesis by using the extramedullary positioning instrument on the theory of rKA alignment showed a good clinical outcome at a short follow up.
ABSTRACT
ObjectiveTo investigate the effects of transcutaneous auricular vagus nerve stimulation (taVNS) combined with bilateral arm training (BAT) on upper limb motor function of hemiplegic stroke patients. MethodsFrom January, 2021 to January, 2022，105 stroke patients from Zhejiang Provincial People's Hospital were randomly divided into taVNS group (n = 35), BAT group (n = 35) and combined group (n = 35). All the patients received routine rehabilitation, while taVNS group received taVNS, BAT group received BAT, and the combined group received both taVNS and BAT, for eight weeks. The root mean square (RMS) of surface electromyography in deltoid, triceps brachii and extensor carpi was measured, and the scores of Box and Block Test (BBT), and Fugl-Meyer Assessment-Upper Extremities (FMA-UE) were obtained before and after treatment. ResultsThe RMS of all these muscles, and the scores of BBT and FMA-UE improved in all the three groups after treatment (|t| > 6.124, P < 0.001), and they were improved the most in the combined group (F > 18.162, P < 0.001). ConclusionBoth taVNS and BAT can enhance the muscle strength on the affected upper limb, increase the hand flexibility, and improve upper limb motor function of stroke patients, while the combination of both methods is more effective.
ABSTRACT
ObjectiveTo explore low-frequency repetitive transcranial magnetic stimulation (rTMS) combined with bilateral isokinematic training (BIT) on upper limb motor function and activities of daily living of stroke patients. MethodsFrom September, 2021 to September, 2022, 60 stroke inpatients in Zhejiang Provincial People's Hospital were randomly divided into rTMS group (n = 20), BIT group (n = 20) and combination group (n = 20). All the patients accepted routine rehabilitation, moreover, rTMS group accepted 1 Hz rTMS on healthy side, BIT group accepted BIT, and the combination group accepted the combination of 1 Hz rTMS on healthy side and BIT, for four weeks. They were evaluated with Fugl-Meyer Assessment-Upper Extremities (FMA-UE), Wolf Motor Function Test (WMFT), Carroll Upper Extremities Function Test (UEFT) and modified Barthel Index (MBI) before and after treatment. ResultsThe scores of FMA-UE, WMFT, UEFT and MBI significantly improved in all the groups after treatment (|t| > 5.052, P < 0.001), and improved the most in the combination group (F > 9.834, P < 0.001). ConclusionBoth low-frequency rTMS and BIT can effectively improve upper limb motor function and activities of daily living of stroke patients, and the combination of them is more effective.
ABSTRACT
OBJECTIVE@#To investigate the prognostic value of death-associated protein 5 (DAP5) in gastric cancer (GC) and its regulatory effect on aerobic glycolysis in GC cells.@*METHODS@#We analyzed DAP5 expression levels in GC and adjacent tissues and its association with survival outcomes of GC patients using public databases. We collected paired samples of GC and adjacent tissues from 102 patients undergoing radical resection of GC in our hospital from June, 2012 to July, 2017, and analyzed the correlation of DAP5 expression level detected immunohistochemically with the clinicopathological parameters of the patients. Cox regression analysis, Kaplan-Meier analysis, and ROC curves were used to explore the independent risk factors and the predictive value of DAP5 expression for 5-year survival of the patients. In the cell experiments, we observed the changes in aerobic glycolysis in MGC-803 cells following lentivirus-mediated DAP5 knockdown or overexpression by measuring glucose uptake and cellular lactate level and using qRT-PCR and Western blotting.@*RESULTS@#Analysis using the public databases showed that DAP5 was highly expressed in GC and correlated with tumor progression and poor survival outcomes of the patients (P < 0.05). In the clinical samples, DAP5 expression was significantly higher in GC than in the adjacent tissues (3.19±0.60 vs 1.00±0.12; t=36.863, P < 0.01), and a high expression of DAP5 was associated with a reduced 5-year survival rate of the patients (17.6% vs 72.5%; χ2=29.921, P < 0.05). A high DAP5 expression, T3-4, N2-3, and CEA≥5 ng/mL were identified as independent risk factors affecting 5-year survival outcomes of GC (P < 0.05), for which DAP5 expression showed a prediction sensitivity, specificity and accuracy of 73.2%, 80.4% and 79.0%, respectively. In MGC-803 cells, DAP5 knockdown significantly reduced glucose uptake, lactate level and the expressions of GLUT1, HK2 and LDHA, and DAP5 overexpression produced the opposite effects (P < 0.05).@*CONCLUSION@#A high expression of DAP5 in GC, which enhances cellular aerobic glycolysis to promote cancer progression, is correlated with a poor survival outcome and may serve as a biomarker for evaluating long-term prognosis of GC patients.

OBJECTIVE@#To investigate the effect of pachymic acid (PA) against TNBS-induced Crohn's disease (CD)-like colitis in mice and explore the possible mechanism.@*METHODS@#Twenty-four C57BL/6J mice were randomized equally into control group, TNBS-induced colitis model group and PA treatment group. PA treatment was administered via intraperitoneal injection at the daily dose of 5 mg/kg for 7 days, and the mice in the control and model groups were treated with saline. After the treatments, the mice were euthanized for examination of the disease activity index (DAI) of colitis, body weight changes, colon length, intestinal inflammation, intestinal barrier function and apoptosis of intestinal epithelial cells, and the expressions of TNF-α, IL-6 and IL-1β in the colonic mucosa were detected using ELISA. The possible treatment targets of PA in CD were predicted by network pharmacology. String platform and Cytoscape 3.7.2 software were used to construct the protein-protein interaction (PPI) network. David database was used to analyze the GO function and KEGG pathway; The phosphorylation of PI3K/AKT in the colonic mucosal was detected with Western blotting.@*RESULTS@#PA significantly alleviated colitis in TNBS-treated mice as shown by improvements in the DAI, body weight loss, colon length, and histological inflammation score and lowered levels of TNF-α, IL-6 and IL-1β. PA treatment also significantly improved FITC-dextran permeability, serum I-FABP level and colonic transepithelial electrical resistance, and inhibited apoptosis of the intestinal epithelial cells in TNBS-treated mice. A total of 248 intersection targets were identified between PA and CD, and the core targets included EGFR, HRAS, SRC, MMP9, STAT3, AKT1, CASP3, ALB, HSP90AA1 and HIF1A. GO and KEGG analysis showed that PA negatively regulated apoptosis in close relation with PI3K/AKT signaling. Molecular docking showed that PA had a strong binding ability with AKT1, ALB, EGFR, HSP90AA1, SRC and STAT3. In TNBS-treated mice, PA significantly decreased p-PI3K and p-AKT expressions in the colonic mucosa.@*CONCLUSION@#PA ameliorates TNBS-induced intestinal barrier injury in mice by antagonizing apoptosis of intestinal epithelial cells possibly by inhibiting PI3K/AKT signaling.

ObjectiveTo investigate the effect of multimodal mirror therapy on upper limb and hand function in stroke patients. MethodsFrom April, 2021 to August, 2022, 60 stroke patients from the Department of Rehabilitation Medicine of Zhejiang Provincial People's Hospital were randomly divided into group A (n = 20), group B (n = 20) and group C (n = 20). All the patients accepted routine rehabilitation, while group B accepted mirror therapy, and group C accepted multimodal mirror therapy, in addition, for six weeks. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE), Upper Extremity Function Test (UEFT) and modified Barthel Index (MBI), while the maximum grip strength and pinch strength of the affected hand were measured. ResultsThe FMA-UE score, UEFT score, maximum hand grip strength and pinch strength, and MBI scores improved in all groups after treatment (|t| > 7.878, P < 0.001), and it was the most in group C (F > 12.563, P < 0.001). ConclusionMultimodal mirror therapy may further improve the upper limb motor function and hand function of stroke patients, as well as the strength of the affected hand and the activities of daily living.
ABSTRACT
Portal hypertension-related complications are the major cause of death in patients with advanced chronic liver disease (ACLD). Hepatic venous pressure gradient is the golden standard for assessing portal hypertension, and upper gastrointestinal endoscopy is an important method for screening and assessing esophageal and gastric varices and its severity; both methods are invasive and inappropriate for portal hypertension screening and monitoring. Noninvasive approaches, such as transient elastography, acoustic radiation force impulse, and shear wave elastography, have been used for the evaluation of portal hypertension in ACLD patients, especially the screening, stratified diagnosis, and monitoring of clinically significant portal hypertension.
ABSTRACT
The new consensus on portal hypertension issued by Baveno Cooperative Group, i.e., the Baveno Ⅶ consensus, summarizes the diagnostic criteria for portal hypertension, noninvasive screening and diagnosis, primary prevention including etiological treatment and non-etiological treatment, secondary prevention including endoscopy and vascular intervention for diagnosis and treatment, new concepts associated with decompensated liver cirrhosis, and major advances and research agenda for the research directions including liver vascular diseases. Baveno Ⅶ consensus has an important reference value for clinical practice and research in the related fields of portal hypertension in China. As a part of the special issue, this article briefly describes the advances and challenges in portal hypertension in China from the perspective of clinical practice.
ABSTRACT
Objective@#To analyze the epidemiological characteristics of infectious diseases at schools in Beijing from 2010 to 2020, providing evidence for the prevention and control strategies in school infectious diseases.@*Methods@#Information on public health emergencies was collected from Public Health Emergency Reporting System (the subsystem of Chinese Disease Prevention and Control Information System) reported from 2010 to 2020.@*Results@#A total of 146 public health emergencies and 138 public health emergencies of infectious diseases in schools were reported in Beijing from 2010 to 2020, including 4 291 cases with the rate of 2.32% and affected or exposed 185 179 cases. There were significant difference in mean annual incidence rates( χ 2=782.46, P <0.01). There were 71 events of respiratory infectious diseases and 66 events of intestinal infectious diseases, accounting for 51.45% and 47.83%, respectively. The annual incidence peaks of public health emergencies of infectious diseases were during March-June and October-December. The events mainly occurred in kindergartens and primary schools among each stage of school periods with 51 and 46 incidences respectively, which accounted for 70.29% of the total number of public health emergencies in schools. The leading infectious diseases among all the reported events in kindergartens and primary schools were hand foot mouth disease and varicella. Varicella and other infectious diarrhoeal diseases were at the top lists of infectious disease outbreaks at the secondary and university stages.@*Conclusion@#Infectious diseases events were the major type of public health emergencies at schools in Beijing from 2010 to 2020. Respiratory infectious diseases and intestinal infectious diseases were the keys to the prevention and control of public health emergencies related to school. It is necessary to strengthen the surveillance for public health emergencies especially for symptom surveillance. The prevention and control measures should be taken according to the characteristics of different age groups. At the same time, the prevention and control of school infectious diseases and the drill of the plan during peak periods need to be particularly strengthened.
ABSTRACT
Objective:To compare the fully covered self-expanding metal stents (FCSEMS) and multiple plastic stents (MPS) in the effectiveness, safety and cost-effectiveness for benign bile duct strictures.Methods:A single-center retrospective study was conducted to analyze the clinical data of 107 patients with benign biliary strictures who underwent FCSEMS or MPS implantation through endoscopic retrograde cholangiopancreatography (ERCP) in Hangzhou First People's Hospital from January 2013 to June 2019.There were 54 cases in group FCSEMS and 53 cases in group MPS. Benign biliary stricture was confirmed by computed tomography (CT), magnetic resonance cholangiopancreatography (MRCP) and endoscopic ultrasonography. The primary index was the rate of stricture remission, and the secondary indices were the incidence of stricture recurrence, ERCP-related complications, the rate of stent migration, hospital stay and charges.Results:The median follow-up times were 10.0 (6.5, 18.0) months and 12.0 (9.0, 20.0) months in group FCSEMS and in group MPS respectively ( P>0.05). The rates of stricture remission in the two groups were 87.0% (47/54) and 83.0% (44/53), the incidences of stricture recurrence were 14.6% (6/41) and 23.5% (8/34), and the incidences of ERCP-related complications were 14.8% (8/54) and 11.9% (13/109), respectively. And the differences were not statistically significant (all P>0.05). But the stent migration rates of the two groups were 22.9% (11/54) and 2.8% (3/109) with significant difference ( P<0.001). Cost-effectiveness analysis showed that the median numbers of ERCP intervention in the two groups were 2 (2,2) times and 3 (2,4) times ( P<0.001), and the median hospital stays were 6.0 (4.0,11.0) days and 9.0 (6.5,16.0) days respectively ( P=0.009). The median hospitalization expenses of the two groups were 44 646 yuan and 51 355 yuan without significant difference ( P>0.05). Conclusion:The effectiveness, safety and cost of FCSEMS for benign bile duct stenosis are similar to those of MPS, but it reduces ERCP intervention and treatment cycles. Even with a certain migration rate, it can still be a first-line treatment approach.

ABSTRACT
Based on the theory of "spleen dispersing essence" in Huangdi's Inner Canon, combined with the discussion of medical experts in previous dynasties and modern researches, this paper argues that "spleen not dispersing essence" is an important pathogenesis of diabetes, which runs through the whole process of diabetes, including the stage of its complications. In the pathological state, the spleen disperses semen, affecting the physiological functions of the viscera, and the occurrence of diabetic retinal, heart, kidney, peripheral nerve and other complications. In clinical practice, the general principle of "promoting the spleen and dispersing essence" is used to provide the idea of TCM syndrome differentiation for the treatment of diabetes and its complications.
ABSTRACT
Objective:To prepare polyvinyl alcohol (PVA) and hydroxyapatite (HA) composite embolization microspheres and investigate their physicochemical properties.Methods:PVA/HA composite embolization microspheres were prepared by reverse suspension polymerization, using PVA and HA as dispersed phases, liquid paraffin containing sorbitan fatty acid ester as the continuous phase, and glutaraldehyde as the cross-linking agent. The morphology, particle size distribution, and microscopic morphology of PVA/HA composite embolization microspheres were observed by optical microscopy and scanning electron microscopy. The chemical structure of PVA/HA composite embolization microspheres and the elasticity, drug loading, and drug release properties of PVA/HA composite bolus microspheres were characterized by Fourier infrared spectroscopy.Results:The PVA/HA composite embolization microspheres were internal, porous round spheres with a particle size distribution of 50-300 μm. The elastic properties of PVA/HA composite embolization microspheres were(13.6±0.145) kPa, which was 2.28 times that of PVA microspheres, and the drug loading capacity and encapsulation efficiency were (76.80±1.22) mg/g and (38.4±12.7)%, respectively. The maximum cumulative release rate of the microspheres within 7 days was (7.37±0.101)%, and the maximum cumulative release was (256.2±9.8) μg.Conclusions:PVA/HA composite embolization microspheres have good mechanical properties and drug-loading and drug-releasing properties, which provide an important reference for their use as medical devices.
ABSTRACT
To evaluate the clinical efficacy and safety of Hot AXIOS, a novel luminal metal stent with a cautery system guided by endoscopic ultrasound, for the treatment of infected pancreatic necrosis (IPN), 5 cases of IPN treated with endoscopic ultrasound-guided Hot AXIOS placement in Hangzhou First People's Hospital from December 2021 to January 2022 were retrospectively analyzed. The results showed that all 5 cases successfully completed the treatment, with 8-21 minutes of the operation time. The symptoms of abdominal pain and bloating on the first day after operation were significantly relieved, and the abdominal CT showed that the walled-off necrosis was significantly reduced. After 2-9 times of direct endoscopic necrosectomy, supplemented by antibiotics, patient's temperature and blood inflammatory indexes returned to normal, the cavity was reduced and necrosis was removed. The Hot AXIOS stent was indwelled for 12-40 days and then removed. After 25-113 days of the follow-up, all patients survived without recurrence. Preliminary results suggest that endoscopic ultrasound-guided Hot AXIOS placement is safe and effective for the treatment of IPN.
