Puncturing has been recognized as a promising technology to cope with the coexistence problem of enhanced mobile broadband(eMBB) and ultra-reliable low latency communications(URLLC)traffic. However, the steady performance of eMBB traffic while meeting the requirements of URLLC traffic with puncturing is a major challenge in some realistic scenarios. In this paper, we pay attention to the timely and energy-efficient processing for eMBB traffic in the industrial Internet of Things(IIoT), where mobile edge computing(MEC) is employed for data processing. Specifically, the performance of eMBB traffic and URLLC traffic in a MEC-based IIoT system is ensured by setting the threshold of tolerable delay and outage probability, respectively. Furthermore,considering the limited energy supply, an energy minimization problem of eMBB device is formulated under the above constraints, by jointly optimizing the resource blocks(RBs) punctured by URLLC traffic, data offloading and transmit power of eMBB device. With Markov's inequality, the problem is reformulated by transforming the probabilistic outage constraint into a deterministic constraint. Meanwhile, an iterative energy minimization algorithm(IEMA) is proposed.Simulation results demonstrate that our algorithm has a significant reduction in the energy consumption for eMBB device and achieves a better overall effect compared to several benchmarks. 展开更多

Objective To observe influence of kinetic needling on functional restoration of upper limbs of patients with apoplexy-induced shoulder-hand syndrome. Methods Ninety patients were randomly divided into an observation group (45 cases) and a control group (45 cases). Basic treatments selected according to corresponding stroke units were applied to both groups. Besides, scalp acupuncture at Dingnie Qianxiexian (MS 6, 顶颞前斜线), Dingnie Houxiexian (MS 6, 顶颞前斜线) and Dingzhongxian (NS 5, 顶中线), was applied in the treatment group. In the observation group, active and passive movement was carried out during the process of scalp acupuncture, and then needling plus bloodletting puncturing and cupping was applied. In the control group, only needling plus blood-letting puncturing and cupping was given. Therapeutic effects, pain scoring obtained by visual analogue scales (VAS), FugI-Meyer and FugI-Meyer's scoring reflecting moving functions of upper limbs were made after 4 courses of treatments in both groups. Results The total effective rate was 95.5% and 91.1% in the observation group and control group, respectively, showing superiority of the former to the latter (P〈0.05). After treatment, VAS scores were all obviously reduced in both groups (P〈0.01), and the reduction in the former was significantly more than that in the latter (P〈0.01). Moving functions of upper limbs shown by Fugl-Meyer's scoring were improved after 2 courses of treatment in both groups (P〈0.01). The improvement was more obvious after 4 courses of treatment than that after 2 courses of treatment in both groups (P〈0.05). After 4 courses of treatment, moving functions shown by FugI-Meyer's scoring were more remarkably improved in the observation group than those in the control group(t=3.9, P〈0.01). Conclusion Both kinetic needling combined with needling plus blood-letting puncturing and cupping and simple needling plus blood-letting puncturing and cupping are effective in treating shoulder-hand syndrome after apoplexy, and the former is better than the latter. 展开更多

BACKGROUND Severe acute pancreatitis(SAP),a condition with rapid onset,critical condition and unsatisfactory prognosis,poses a certain threat to human health,warranting optimization of relevant treatment plans to improve treatment efficacy.AIM To evaluate the efficacy and safety of computerized tomography-guided the-rapeutic percutaneous puncture catheter drainage(CT-TPPCD)combined with somatostatin(SS)in the treatment of SAP.METHODS Forty-two SAP patients admitted to The Second Affiliated Hospital of Fujian Medical University from June 2020 to June 2023 were selected.On the basis of routine treatment,20 patients received SS therapy(control group)and 22 patients were given CT-TPPCD plus SS intervention(research group).The efficacy,safety(pancreatic fistula,intra-abdominal hemorrhage,sepsis,and organ dysfunction syndrome),abdominal bloating and pain relief time,bowel recovery time,hospital stay,inflammatory indicators(C-reactive protein,interleukin-6,and pro-calcitonin),and Acute Physiology and Chronic Health Evaluation(APACHE)II score of both groups were evaluated for comparison.RESULTS Compared with the control group,the research group had a markedly higher total effective rate,faster abdominal bloating and pain relief and bowel recovery,INTRODUCTION Pancreatitis,an inflammatory disease occurring in the pancreatic tissue,is classified as either acute or chronic and is associated with high morbidity and mortality,imposing a socioeconomic burden[1,2].The pathogenesis of this disease involves early protease activation,activation of nuclear factor kappa-B-related inflammatory reactions,and infiltration of immune cells[3].Severe acute pancreatitis(SAP)is a serious condition involving systemic injury and subsequent possible organ failure,accounting for 20%of all acute pancreatitis cases[4].SAP is also characterized by rapid onset,critical illness and unsatisfactory prognosis and is correlated with serious adverse events such as systemic inflammatory response syn-drome and acute lung injury,threatening the health of patients[5,6].Therefore,timely and effective therapeutic inter-ventions are of great significance for improving patient prognosis and ensuring therapeutic effects.Somatostatin(SS),a peptide hormone that can be secreted by endocrine cells and the central nervous system,is in-volved in the regulatory mechanism of glucagon and insulin synthesis in the pancreas[7].It has complex and pleiotropic effects on the gastrointestinal tract,which can inhibit the release of gastrointestinal hormones and negatively modulate the exocrine function of the stomach,pancreas and bile,while exerting a certain influence on the absorption of the di-gestive system[8,9].SS has shown certain clinical effectiveness when applied to SAP patients and can regulate the severity of SAP and immune inflammatory responses,and this regulation is related to its influence on leukocyte apoptosis and adhesion[10,11].Computerized tomography-guided therapeutic percutaneous puncture catheter drainage(CT-TPPCD)is a surgical procedure to collect lesion fluid and pus samples from necrotic lesions and perform puncture and drainage by means of CT image examination and precise positioning[12].In the research of Liu et al[13],CT-TPPCD applied to pa-tients undergoing pancreatic surgery contributes to not only good curative effects but also a low surgical risk.Baudin et al[14]also reported that CT-TPPCD has a clinical success rate of 64.6%in patients with acute infectious necrotizing pan-creatitis,with nonfatal surgery-related complications found in only two cases,suggesting that this procedure is clinically effective and safe in the treatment of the disease.In light of the limited studies on the efficacy and safety of SS plus CT-TPPCD in SAP treatment,this study performed a relevant analysis to improve clinical outcomes in SAP patients. 展开更多

Objective:To evaluate the feasibility and the safety of medial non-papillary percutaneous nephrolithotomy(npPCNL)for the management of large proximal ureteral stones.Methods:We evaluated prospectively collected data of 37 patients with large proximal ureteral stones more than 1.5 cm in diameter treated by prone npPCNL.Depending on stone size,in-toto stone removal or lithotripsy using the Lithoclast®Trilogy(EMS Medical,Nyon,Switzerland)was performed.Perioperative parameters including operative time(from start of puncture to the skin suturing),stone extraction time(from the first insertion of the nephroscope to the extraction of all stone fragments),and the stone-free rate were evaluated.Results:Twenty-one males and 16 females underwent npPCNL for the management of large upper ureteral calculi.The median age and stone size of treated patients were 58(interquartile range[IQR]:51-69)years and 19.3(IQR:18.0-22.0)mm,respectively.The median operative time and stone extraction time were 25(IQR:21-29)min and 8(IQR:7-10)min,respectively.One case(2.7%)of postoperative bleeding and two cases(5.4%)of prolonged fever were managed conservatively.The stone-free rate at a 1-month follow-up was 94.6%.Conclusion:The npPCNL provides a straight route to the ureteropelvic junction and proximal ureter.Approaching from a dilated portion of the ureter under low irrigation pressure with larger diameter instruments results in effective and safe stone extraction within a few minutes. 展开更多

BACKGROUND Ultrasound-guided prostate biopsy is a reliable diagnostic procedure for prostate cancer diagnosis with minimal procedure-related trauma.However,complications,such as massive rectal bleeding may occur after the puncture.We hypothesized that using a transrectal resectoscope could help treat massive rectal bleeding after transrectal prostate punctures.AIM To identify a simple and effective treatment for massive rectal bleeding after transrectal prostate punctures.METHODS Patients requiring treatment for massive rectal bleeding after transrectal prostate punctures were included.A SIMAI resectoscope was inserted through the anus.Direct electrocoagulation was performed for superficial bleeding points.Part of the rectal mucosa or surface muscle layer was removed to expose deep bleeding points,followed by electrocoagulation.An electric cutting ring was used to compress and stop the bleeding for jet-like points before electrocoagulation.The fluid color in the drainage tube was monitored postoperatively for continuous bleeding.RESULTS Eight patients were included from 2012 to 2022.None of the patients with massive rectal bleeding after the transrectal prostate punctures improved with conventional conservative and blood transfusion treatments.Two patients had an inferior artery embolism,and digital subtraction angiography was ineffective.All patients received emergency transanal prostate resection,which immediately stopped the bleeding.Four days after the procedure,the patients had recovered and were discharged.CONCLUSION Using a transanal prostate resection instrument is a simple,safe,and effective method for treating massive rectal bleeding after transrectal prostate punctures. 展开更多

Introduction: Even though lumbar puncture (LP) represents an important tool in the diagnosis of certain neurological diseases, this procedure is little practiced by our students. We aimed to evaluate the attitudes and practices of students, interns, and residents about LP, and to assess their feelings about how this procedure is taught. Materials and Methods: We conducted a cross-sectional study of 160 participants, using an anonymous questionnaire, to evaluate the attitudes and practices of students, interns and residents in the pediatrics department concerning lumbar puncture. Results: Half of the participants had never performed LP, usually because of the risk involved or lack of confidence, while 20% had performed it more than 4 times. None of the participants had learned to perform the procedure through simulation sessions, while (42%) had learned it under the supervision of a senior physician and had not been able to perform it successfully the first time. Most participants inform the patient about the procedure before performing it. Only 44% of participants acknowledged that LP can be performed under local anesthetic. The sitting position (60%) was by far the most commonly used. Most LPs were performed for diagnostic purposes. Most participants stated that the pediatric ward and the pediatric emergency department are among the departments that perform LP most frequently, and that they would be interested in taking part in simulated lumbar puncture sessions in children in the future. Conclusion: The results of our study show that LP is perceived by students as a risky procedure that is difficult to perform. Teachers should reconsider how this technical procedure is taught, by integrating simulation on mannequins into student training. 展开更多
