Huimin Insurance is an important exploration of building a multi-level medical security system in China.At present,its sustainable development is in trouble.In order to cope with this dilemma,Based on the perspective of Behavioral Economics,this study incorporates individual psychological factors into the decision-making.This paper also applies behavioral economics to the research of Huimin Insurance,which expands the connotation and application scope of behavioral economics theory.By establishing an insurance purchase decision-making process model based on behavioral economics,three psychological variables of risk perception,concept cognition,and value cognition are extracted from the three stages of insurance purchase decision-making process model.Using the survey data of Huiliao Insurance in Liaoning Province,this paper analyzes the path of psychological variables on Huiliao Insurance's willingness to purchase insurance.The main results show that in the insurance purchase decision-making,there is a sequential relationship between variables,and there is a path of"risk perception→concept cognition→value cognition→purchase intention".Concept cognition and value cognition play a chain mediating role.At the same time,there is a leap between the action paths,which is mainly manifested in the fact that conceptual cognition and value cognition play a role between risk perception and insurance purchase intention as separate intermediaries.There are two paths:"perception→conceptual cognition→insurance purchase intention"and"risk perception→value cognition→insurance purchase intention".Based on the above conclusions,this study puts forward the following suggestions:Deepen health risk education and enhance public risk awareness;strengthen the publicity and promotion of Huimin Insurance,improve awareness and value cognition;establish a user feedback mechanism to continuously optimize products and services.

Circular RNAs (circRNAs) are a kind of non-coding RNA (ncRNA) with covalent closed-loop structure. They have attracted more and more attention because of their high stability, evolutionary conservatism, and tissue expression specificity. It has shown that circRNAs are involved in the development of a variety of diseases including malignant tumors recently. Nasopharyngeal carcinoma (NPC) is a malignant tumor that occurs in the nasopharynx and has a unique ethnic and geographical distribution in South China and Southeast Asia. Epstein-Barr virus (EBV) infection is closely related to the development of NPC. Radiotherapy and chemotherapy are the mainstays of treatment for NPC. But tumor recurrence or distant metastasis is the leading cause of death in patients with NPC. Several studies have shown that circRNAs, as gene expression regulators, play an important role in NPC and affect the progression of NPC. This review mainly summarized the research status of abnormally expressed circRNAs in NPC and EBV-encoded circRNAs. We also discussed the possibility of circRNAs as a therapeutic target, diagnostic and prognostic marker for NPC.

Adequate inflammation can effectively eliminate harmful substances and prevent disease as a self-protective measure to prevent further damage to the body,while abnormally activated inflammation is detrimental to the body.Nucleotide binding and oligomerization domain-like receptor protein 3(NLRP3)inflammasome that participates in inflammatory responses are closely related to many physiological and pathological processes and play an important role in the occurrence and development of pulmonary diseases.This article mainly reviewed the activation mechanism and hypothesis of NLRP3 inflammasome,as well as the research on treating respiratory diseases by interfering with NLRP3 inflammasome.

Objective To explore the risk factors related to afterload mismatch(AM)after transcatheter mitral valve repair(MitraClip).Methods This was a retrospective cohort study.48 patients hospitalized in the Department of Cardiovascular Medicine,the First Affiliated Hospital of Sun Yat-sen University from December 2021 to December 2023,who underwent MitraClip due to severe mitral regurgitation(MR)were included.Preoperative clinical data,laboratory tests,and preoperative and postoperative color Doppler echocardiographic examination results of surgical patients were collected.AM was defined as the left ventricular ejection fraction(LVEF)decreased by 15％or more after surgery compared with the one before(dLVEF≤-15％).Patients were divided into AM group and non-AM group according to whether afterload mismatch occurred.Univariate and multivariate logistic regression were used to analyze the risk factors of postoperative AM.Results Among 48 patients who underwent MitraClip,14 of them(29.2％)developed afterload-mismatched.For those without AM,their overall LVEF was improved after the operation;for patients in both AM group and non-AM group,their overall left ventricular end-diastolic diameter(LVEDd),left ventricular end-diastolic diameter volume index(LVEDVi)was reduced compared with the preoperative ones.Univariate regression analysis showed that C-reactive protein levels(OR 1.98,95％CI 1.02-3.83),platelets(OR 2.22,95％CI 1.08-4.53),systemic immune inflammation index(OR 1.96,95％CI 1.03-3.71)were associated with an increased risk of AM in patients undergoing MitraClip(all P＜0.05),while those with larger right atrial diameter(OR 0.35,95％CI 0.13-0.93)or moderate to severe tricuspid regurgitation(OR 0.19,95％CI 0.05-0.81)were less likely to develop into AM(both P＜0.05),which is still satisfied after adjustment.Conclusions For patients who underwent MitraClip,C-reactive protein levels,platelets and systemic immune inflammation index(SII)are associated with an increased risk of afterload mismatched,while those with larger right atrial diameter or moderate to severe tricuspid regurgitation were less likely to develop into AM.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To investigate the application value of ultrasound technology in transurethral enucleation and resection of the prostate(TUERP).Methods:This study included 78 BPH patients admitted in our hospital from June 2021 to June 2023,aged 70.68±8.63 years and with the indication of surgery.We randomly divided them into two groups to receive TUERP(the control group,n=39)and ultrasound-assisted TUERP(the US-TUERP group,n=39).We statistically analyzed and compared the rele-vant parameters obtained before and after operation between the two groups.Results:No statistically significant differences were ob-served in the operation time and bladder irrigation time between the two groups(P>0.05).More glandular tissues were removed but less intraoperative bleeding and fewer perioperative complications occurred in the US-TUERP group than in the control.Compared with the baseline,IPSS,postvoid residual urine volume(PVR),quality of life score(QOL)and maximum urinary flow rate(Qmax)were significantly improved in both groups at 1 and 3 months after surgery,even more significantly in the US-TUERP than in the control group(P<0.05).Conclusion:US-TUERP helps achieve complete resection of the hyperplastic prostatic tissue along the surgical capsule at the anatomical level,with a higher safety,fewer perioperative complications,and better therapeutic effects.

Objective:To evaluate the safety and efficiency of China-made Toumai Robot-assisted laparoscopic radical prosta-tectomy(LRP).Methods:This study included 40 cases of PCa treated from January 2023 to May 2023 by robot-assisted LRP with preservation of the bladder neck and maximal functional urethral length,15 cases with the assistance of Toumai Robot(the TMR group)and the other 25 with the assistance of da Vinci Robot as controls(the DVR group).We recorded the docking time,laparo-scopic surgery time,vesico-urethral anastomosis time,intraoperative blood loss and postoperative urinary continence,and compared them between the two groups.Results:Operations were successfully completed in all the cases.No statistically significant differ-ences were observed between the TMR and DVR groups in the docking time(6 min vs 5 min,P＞0.05)or intraoperative blood loss(200 ml vs 150 ml,P＞0.05).The TMR group,compared with the DVR group,showed a significantly longer median laparoscopic surgery time(146 min vs 130 min,P＜0.05)and median vesico-urethral anastomosis time(19 min vs 16 min,P＜0.05).There were no statistically significant differences between the TMR and DVR groups in the rates of urinary continence recovery immediately af-ter surgery(60.0％[9/15]vs 64.0％[16/25],P＞0.05)or at 1 month(80.0％[12/15])vs(76.0％[19/25],P＞0.05),3 months(93.3％[14/15])vs(92.0％[23/25],P＞0.05)and 6 months postoperatively(100％[15/15])vs(96％[24/25],P＞0.05).Conclusion:China-made Toumai? Robot surgical system is safe and reliable for laparoscopic radical prosta-tectomy,with satisfactory postoperative recovery of urinary continence.

Objective:To explore the application of modified scrotoscopic surgery(MSS)in the treatment of testicular hydro-cele.Methods:We selected 45 cases of testicular hydrocele for this study,22 treated by traditional scrotoscopic surgery(TSS)and the other 23 by MSS,which was performed with a pin-shaped electrode bent inward at an angle of 60° instead of a circular electrode used in TSS.We recorded the general clinical data,operation time,incision length,intraoperative injury,incision infection,scrotal e-dema,postoperative hospital stay and postoperative Visual Analogue Scale(VAS)scores of the patients and compared them between the two groups.Results:There was no statistically significant difference in the general clinical data between the two groups(P＞0.05).Compared with the patients of the TSS group,those of the MSS group showed significantly shorter operative time([32.86±3.80]vs[26.13±2.81]min,P＜0.05),incision length([14.09±2.23]vs[8.73±1.48]mm,P＜0.05)and postopera-tive hospital stay([4.36±1.05]vs[2.00±0.90]d,P＜0.05),and achieved remarkably lower VAS scores on postoperative days 1(4.41±1.05 vs 3.09±0.79,P＜0.05),2(3.36±1.05 vs 2.78±1.13,P＜0.05),3(2.65±0.72 vs 1.74±0.86,P＜0.05)and 7(1.91±0.81 vs 1.04±0.82,P＜0.05).At 3 and 7 days after surgery,scrotal edema was markedly mil-der in the MSS than in the TSS group(P＜0.05).No testicular or epididymal damage,or wound infection occurred in either of the two groups.Conclusion:MSS is safe and effective in the treatment of testicular hydrocele,superior to TSS for its advantages of shorter operation time,smaller surgical incision,less postoperative pain and milder scrotal edema.

Xiaoyao pills are a famous traditional Chinese medicine collected in Welfare Pharmacy, which is a classic prescription for treating liver depression and spleen deficiency. However, its composition is complex. In order to better control the quality of Xiaoyao pills, in this study, HPLC-ion-trap time-of-flight mass spectrometry (LC-IT-TOF/MS) was used to identify the main ingredients of Xiaoyao pills, paeoniflorin, albiflorin, glycyrrhizic acid, saikosaponin A and saikosaponin B2. Then a liquid chromatography tandem mass spectrometry (LC-MS/MS) was developed for simultaneous determination and quantification of the main compounds. Fragmentation pathways of five active components were obtained. The method was validated. Five active ingredients in Xiaoyao pills had a good linear relationship, and the values of RSD (%) of repeatability were all less than 5%, the recovery ranges were between 90% and 115%, and the values of RSD (%) of each substance were less than 10% after the sample solution is placed for 24 hours. Three batches of Xiaoyao pills (concentrated pellets) and two batches of Xiaoyao pills (water pellets) were determined, the contents of paeoniflorin in concentrated pills were more than 4.0 mg·g^-1, and those in water pills were more than 2.5 mg·g^-1, which was accordance with Chinese Pharmacopoeia. However, other compounds behave differently. This method has high sensitivity and reliable measurement results, which provides basis for quality control of Xiaoyao pills and material basis for pharmacology research.

AIM:To investigate the efficacy of domestic cyclosporine A(CsA)in dry eye and its effect on sub-basal nerves(SBN)by observing quantitative and morphological changes in corneal SBN of patients with moderate to severe dry eye before and after the treatment with 0.05% CsA eye drops(Ⅱ).METHODS: In this prospective study, a total of 20 patients(20 eyes)with moderate to severe dry eye who admitted to the ophthalmology department of the Affiliated Eye Hospital of Nanchang University from December 2020 to January 2022 were selected. They were treated with domestic CsA and followed up for 3mo. Clinical evaluation was carried out at baseline and at 3mo after treatment. The changes in clinical symptoms, signs and morphology and quantity of SBN were observed.RESULTS: The ocular surface disease index(OSDI)score, the tear break-up time(TBUT), Schirmer Ⅰ, corneal fluorescein staining(CFS)score were significantly improved at 3mo after treatment. Confocal microscopy data analysis showed that SBN density increased from 13.49±5.43 mm/mm2 to 14.93±5.34 mm/mm2(P<0.001), nerve curvature scores decreased from 2.86±0.92 to 2.31±0.75(P<0.001), number of beaded structure decreased from 1.45±0.67/100μm to 1.07±0.45/100μm(P<0.001), and the number of dendritic cell(DC)decreased from 5.83±3.28 per frame to 3.67±2.24 per frame at 3mo after treatment(P<0.001). The number of DC was positively correlated with the number of branch nerves, the grade of nerve curvature and the number of nerve bead.(rs=0.27, P=0.045; rs=0.407, P<0.01; rs=0.486, P<0.01).CONCLUSIONS: Nerve injury was positively correlated with corneal inflammation caused by dry eye, and 0.05%CsA eye drops(II)could effectively inhibit inflammation and improve the morphology and quantity of corneal SBN. Observation of corneal SBN via in vivo confocal microscopy can be used as an effective method to evaluate the therapeutic effect of dry eye patients.
