BACKGROUND:Spinal canal decompression using uniportal endoscopic surgery is a new minimally invasive surgery in the treatment of lumbar spinal stenosis.However,this technique needs a steep learning curve and high requirements for surgical equipment and instruments,which limits its clinical application.We previously use the spinal endoscopy as a monitoring endoscopy and combined with unilateral biportal endoscopy to propose a hybrid technique of spinal endoscopy to achieve coaxial endoscopic operation and hands-separate operation. OBJECTIVE:To compare the clinical outcome of hybrid technique and uniportal endoscopic surgery in treatment of lumbar spinal stenosis with bilateral lower limb pain symptoms. METHODS:Ninety patients diagnosed of lumbar spinal stenosis with bilateral symptoms were included and retrospectively analyzed at First People's Hospital,Shanghai Jiao Tong University from August 2020 to August 2022.44 cases were included in group A(hybrid technique group),while 46 cases were included in group B(uniportal endoscopic surgery).The nerve decompression was observed during the surgery.Operation time,hospital stay time,and expenses were recorded in both groups.The visual analog scale scores of lower back pain and both lower extremities pain,Oswestry disability index scores of quality of life and excellent and good rate of modified Macnab criteria were recorded and compared at preoperative,postoperative 3 days,and postoperative 3 and 6 months. RESULTS AND CONCLUSION:(1)The operation time of group A was significantly shorter than that of group B(P<0.05).(2)The lower back pain and lower extremity pain of the severe side at postoperative 3 days,and 3 and 6 months were significantly relieved in both groups(P<0.05).The visual analog scale score of lower extremity pain on the mild side was significantly decreased at postoperative 3 days,3 and 6 months than preoperative score in the group A(P<0.05).The visual analog scale score of lower extremity pain on the mild side was significantly decreased at postoperative 3 days than preoperative score in the group B(P<0.05).The visual analog scale scores of lower extremity pain on the mild side at postoperative 3 and 6 months did not show significant difference than preoperative score in the group B.The comparison between the two groups showed that there was no significant difference in the visual analog scale scores of postoperative lower back pain and lower extremity pain of the severe side(P>0.05).The visual analog scale scores of lower extremity pain on the mild side in the group A were significantly lower than those of group B at postoperative 3 and 6 months(P<0.05).(3)The Oswestry disability index scores of both groups at postoperative 3 day were significantly lower than preoperative score(P<0.05),and there was no significant difference between the two groups 3 days after operation.Oswestry disability index scores of group A at postoperative 3 and 6 months were significantly decreased than preoperative score(P<0.05).The Oswestry disability index scores of group B at postoperative 3 and 6 months did not show significant differences than preoperative score(P>0.05).The comparison between the two groups showed the Oswestry disability index scores of group A were significantly lower than group B at postoperative 3 and 6 months(P<0.05).(4)The results of modified Macnab showed that the excellent and good rate of group A was significantly higher than that of group B(95%,78%,P<0.05).(5)It is indicated that the hybrid technique is a new spinal endoscopy technique,which has the advantages of less trauma and faster recovery as a minimally invasive surgery.The clinical outcome of hybrid technique is superior to that of uniportal endoscopic surgery in the treatment of lumbar spinal stenosis with bilateral symptoms.Additionally,it also has the advantages of good operational flexibility and high decompression efficiency as an open surgery.

Objective:To explore the clinical efficacy and safety analysis of a novel laser localization technology assisted percutaneous puncture of trigeminal nerve microsphere capsule compression surgery for the treatment of primary trigeminal neuralgia.Methods:A retrospective selection was conducted on 63 patients with primary trigeminal neuralgia who underwent percutaneous puncture of the trigeminal nerve microsphere capsule compression surgery at the First Hospital of Hunan University of Chinese Medicine from January 2020 to December 2021. According to different surgical methods, they were divided into a new laser localization assisted puncture group (observation group) of 32 cases and a traditional barehanded localization puncture group (control group) of 31 cases. An analysis was conducted on the surgical time, puncture time, puncture frequency, intraoperative exposure to radiation, number of cases of poor balloon formation, and clinical efficacy within 6 months after surgery for two groups of patients. The prognosis of the patients was followed up at 6 months after surgery.Results:The surgical time, puncture time, puncture frequency, and intraoperative exposure of the observation group were all less than those of the control group, and the differences were statistically significant (all P<0.05). There was no statistically significant difference ( P>0.05) in the number of cases of poor balloon angioplasty between the observation group and the control group, as well as the pain score grading of the Barlow Neurological Institute (BNI) on the first day after surgery. Within 6 months after surgery, there was no statistically significant difference in the incidence of facial numbness, diplopia, masseter weakness, perilabial herpes, and recurrent pain between the two groups of patients (all P>0.05). Conclusions:Laser positioning technology can assist in precise puncture of the foramen ovale and accurate placement of balloons based on surgical experience, which helps to improve surgical safety, reduce postoperative complications and intraoperative radiation dose, and achieve satisfactory short-term follow-up results.

ObjectiveTo establish a vaginal self-sampling HPV cervical cancer screening model in Hainan Province, to analyze the application of p16 protein detection in HPV positive and non-HPV16 /18 shunt screening. MethodsFrom January 2019 to September 2022, a total of 200 women from the targeted population was randomly selected for vaginal self-sampling HPV typing test to screen cervical cancer using randomized numeric table method, followed by cervical cytology sampling for cytology p16 protein detection. Postoperative pathological examination was used as the gold standard. Multivariate logistic regression analysis was used to analyze the influencing factors of HPV positive detection rate in cervical lesions, and the nomogram model was constructed simultaneously. The receiver operating characteristic(ROC) curve and calibration curve were used for evaluating the accuracy of the nomogram model. Differences in the distribution of self-sampled HPV-positive and HPV infected genotypes were recorded, and the application of p16 protein detection in HPV-positive and non-HPV16/18 shunt screening was analyzed. ResultsAged ≥40 years, BMI ≥28.00 kg·m-2, number of sexual partners ≥2, frequency of sexual life ≥10 times·month-1, bleeding from sexual intercourse, and age of first sexual intercourse <22 years were the risk factors for HPV positive of cervical lesions (all P<0.001). The results of ROC curve and calibration curve showed that the area under ROC curve (AUC) was 0.874 (95%CI: 0.823‒0.907, P<0.05), the sensitivity was 0.835, the specificity was 0.847, and the Youden index was 0.672, indicating a good fit of the model. Results of vaginal self-sampling HPV test showed that the positive rate of HPV was 86.50% (173/200). HPV high-risk infection types mainly included HPV16, 18, 31, 33, 35, 39, 45, 52, 56, 58, 59, 68, 73, and 82. Single HPV infection accounted for 95.95% (166/173), 2.89% (5/173) were infected with two types of HPV, and 1.16% (2/173) were infected with three or more types of HPV. Colposcopic pathologic diagnosis was used as the gold standard, and the results showed that the accuracy of p16 protein detection in the diagnosis of cervical cancer was 93.50% (187/200), with a sensitivity of 96.53% (167/173), and a specificity of 74.07% (20/27). The negative and positive predictive value were 76.92% (20/26) and 95.98% (167/174), respectively. The results of shunt screening showed that there were 80 cases infected with HPV16, 79 cases infected with HPV18 and 41 cases of non-HPV16/18, with a sensitivity of 90.91%, 90.32% and 86.67%, a specificity of 71.43%, 64.71% and 72.73%, a negative predictive value of 62.50%, 64.71% and 66.67%, a positive predictive value of 93.75%, 90.32% and 89.66%, and an accuracy of 87.50%, 84.81% and 82.93%, respectively. The specificity and accuracy of p16 positive screening for cervical cancer were significantly higher than that of HPV positive detection, but the false positive rate was significantly lower than that of HPV positive detection. The AUCs of HPV positive, p16 positive and combination of the two detection methods for cervical cancer were 0.603, 0.822 and 0.907, respectively. ConclusionVaginal self-sampling HPV testing is a widely accepted mode for cervical cancer screening. Cervical cytology p16 protein detection is important for self-sampled HPV positive and shunt screening of non-HPV16/18.

Objective:To explore the current situation and influencing factors of amputation decision-making dilemma of diabetic foot patients.Methods:From July to December 2023, 200 patients with diabetic foot in the Tianjin Medical University General Hospital and Tianjin Medical University Chu Hsien-I Memorial Hospital were selected as study subjects by convenience sampling. General Information Questionnaire, Decisional Conflict Scale (DCS), Family APGAR Index, and Hospital Anxiety and Depression Scale were used to conduct a cross-sectional survey. Pearson correlation was used to analyze the correlation between diabetic foot patients' amputation decision-making dilemma and family caring, anxiety and depression, and multiple linear regression was used to analyze the influencing factors of diabetic foot patients' amputation decision-making dilemma.Results:A total of 200 questionnaires were distributed, and 180 valid questionnaires were collected, with a valid response rate of 90.0% (180/200). The DCS score of 180 patients with diabetic foot was (30.04±9.77), 76.7% (138/180) patients scored ≥25.0, and they had decision-making dilemma, and 25.0% (45/180) of patients scored ≥37.5, indicating decision-making delay. Multiple linear regression analysis showed that occupational status, diabetes course, family caring, anxiety and depression were the influencing factors of amputation decision-making dilemma of diabetic foot patients ( P<0.05) . Conclusions:Diabetic foot patients face certain dilemmas in the process of amputation decision-making. Clinical medical and nursing staff should reasonably evaluate the patient's occupational status, disease course, family caring, and psychological state, and develop personalized decision support strategies to improve decision quality and prevent changes in the patient's condition caused by delayed decision-making.

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.

This study delves into the pivotal factors influencing the consensus process within traditional Chinese medicine guideline development, with the objective of augmenting the quality of this process through methodological recommendations aimed at elevating standardization. Semi-structured qualitative interviews were used to interview guideline leaders, working groups and consensus groups to explore the pertinent elements impacting the credibility of consensus and gather insights into the constitution and progression of the consensus methodology. The study encompassed interviews with 26 participants, yielding 212 codes that were subsequently categorized into five domains: establishment of the consensus group, integration of patient participation, adeptness of the meeting moderator, preparation for consensus formulation, and overarching factors influencing consensus. The research distilled three fundamental phases for forming a consensus group and delineated 17 fundamental tenets for applying the consensus methodology. In forthcoming guideline development endeavors, it is advisable to bolster methodological training ahead of the consensus process while ensuring comprehensive engagement of methodologists. Encouraging experts to navigate differences judiciously and prioritizing meticulous methodology and evidentiary groundwork are recommended. The process should involve openly disclosing the selection of consensus group members, heightening the involvement of patients, and effective management and disclosure of conflicts of interest. This collective approach helps curtail bias, enhance transparency, bolster reliability, and fortify the scientific rigor of consensus outcomes.

Objective:To investigate the prevalence of lymphocytic choriomeningitis virus (LCMV) and hantavirus (HV) specific antibodies among cross-border migrant workers for assessment of the risk of rodents-borne virus infection.Methods:From 2019 to 2020, a survey was conducted on cross border migrant workers engaged in outdoor activities, and serum samples were collected, LCMV specific IgG antibody was detected by an indirect ELISA and Western blot based on recombinant nucleoprotein, and indirect immunofluorescence assay (IFA) based on recombinant expressed glycoprotein. HV IgG antibody in serum was detected by a commercial indirect IgG ELISA kit and IFA based on hantavirus infected Vero cells.Results:A total of 139 cross-border workers, aged 25~57, were surveyed; 64% (89/139) had working experience in multiple countries, involving 26 countries, including 14 countries in Asia and 12 countries in Africa; 11.51% (16/139) of serum samples were tested positive for LCMV antibodies, and the positive samples were verified by Western blot and IFA. The antibody detection rate was slightly higher than the published infection rate from other similar studies. And, HV antibodies were detected from one serum sample (0.72%, 1/139) by ELISA and IFA. However, it was still uncertain when and where the viral infections were acquired.Conclusions:Through this serological cross-sectional preliminary analysis, the infection status and existing risks of LCMV and HV viruses among cross border migrant workers were revealed, which suggested the necessity of strengthening the prevention and control of rodents borne diseases in outdoor engineering sites.

Objective:To investigate the effects of different intensity of lighting on normal refractive development and form deprivation myopia (FDM) in guinea pigs.Methods:A total of 108 healthy 3-week-old guinea pigs were divided into normal refractive development guinea pigs ( n=54) and FDM guinea pigs ( n=54). FDM models were prepared in FDM animals by occlusion of the left eyes using an opaque mask, and the bilateral eyes were open in the normal refractive development guinea pigs.The guinea pigs were randomized to low (20 lx), normal(300 lx), and high intensity-lighting (5 000 lx) groups with a 12-hour light/12-hour dark cycle for 6 consecutive weeks under LED light.The ocular biometry was performed in a two-week interval.Axial length (AL) and dilated diopter were measured by A-scan ultrasonography and retinoscopy, respectively, and were compared after different lighting durations, and the change trends of them in normal refractive development and FDM guinea pigs were evaluated. Results:The AL values were not significantly different among low, normal and high intensity-lighting groups ( Fgroup=0.365, P=0.697), and the AL was gradually prolonged over the lighting duration ( Ftime=353.750, P<0.001). The diopters showed a statistically significant difference among different intensity-lighting groups ( Fgroup=3.576, P=0.034). The diopter in high intensity-lighting for 4 weeks was (+ 2.75±2.15) D, which was significantly higher than (0.41±3.07) D in the normal refrective development guinea pigs ( P<0.001). In the FDM guinea pigs, both AL and diopter were not significantly different among low, normal and high intensity-lighting groups ( Fgroup=0.105, P=0.900; Fgroup=0.973, P=0.387), and significant differences were seen in AL and diopter among three groups ( Ftime=408.302, 27.407; both at P<0.001). The diopter in FDM eyes of low intensity-lighting for 2 weeks was (+ 2.35±1.95) D, which was higher than (+ 1.90±0.97) D before lighting, with no statistically significant difference between them ( P>0.05). The AL was shortest and the AL change was smallest in normal refractive development guinea pigs of high intensity-lighting group.The diopter change in FDM guinea pigs of the low intensity-lighting group was significantly smaller than that in the normal intensity-lighting group ( P<0.001), with a transient hyperopia drift. Conclusions:The 5 000 lx lighting can slow down the development toward myopia in the normal refractive development eyes, and 20 lx lighting tends to delay the progression FDM eyes with a hyperopic shift after lighting for 2 weeks.

Background/Aims:
The incidence of gastroesophageal reflux disease (GERD) is increasing annually. Studies have suggested that psychosocial disorders may be linked to the development of GERD. However, studies evaluating the association between psychosocial disorders and GERD have been inconsistent. Thus, we conducted a systematic review and meta-analysis of observational studies that evaluated the association between psychosocial disorders and GERD.
Methods:
We systematically searched the PubMed, Embase, Cochrane, and Web of Science databases until October 17, 2020. Pooled OR with 95% CI and subgroup analyses were calculated using a random-effects model. Subgroup analyses were performed to identify thesources of heterogeneity. Sensitivity analysis by one-study removal was used to test the robustness of our results.
Results:
This meta-analysis included 1 485 268 participants from 9 studies. Studies using psychosocial disorders as the outcome showed that patients with GERD had a higher incidence of psychosocial disorders compared to that in patients without GERD (OR, 2.57; 95% CI, 1.87-3.54; I2 = 93.8%; P < 0.001). Studies using GERD as an outcome showed an association between psychosocial disorders and an increased risk of GERD (OR, 2.23; 95% CI, 1.42-3.51; I2 = 97.1%; P < 0.001). The results of the subgroup analysis showed that the non-erosive reflux disease group had a higher increased risk of anxiety than erosive reflux disease group (OR, 9.45; 95% CI, 5.54-16.13; I2 = 12.6%; P = 0.285).
Conclusion:
Results
of our meta-analysis showed that psychosocial disorders are associated with GERD; there is an interaction between the two.
