【Objective】 To establish a risk model for predicting spontaneous rupture bleeding of renal angiomyolipoma (RAML) in order to better assess and deal with the risk. 【Methods】 The information of 436 RAML patients diagnosed during Jan.2018 and Dec.2022 was retrospectively analyzed.According to the inclusion and exclusion criteria, 216 patients were included and divided into the rupture bleeding group (n=35) and non-rupture bleeding group (n=181).The factors influencing spontaneous rupture bleeding were identified using univariate and multivariate analysis, and a nomogram was constructed accordingly with R language.The nomogram was evaluated using Calibration curve and area under the receiver operator characteristic curve (AUC). 【Results】 It was found that clinical manifestations, tumor diameter, tumor convexity, tumor blood supply, and tuberous sclerosis complex (TSC) were significantly correlated with rupture bleeding.The Calibration curve fitted well with the nomogram.The AUC was 0.956 (95%CI: 0.856-0.943), indicating that the nomogram had good statistical performance. 【Conclusion】 The model can effectively predict the risk of spontaneous rupture bleeding of renal angiomyolipoma.

Objective:To investigate the application effects of a novel framework: the external septal retention bionic framework in East Asian rhinoplasty.Methods:A retrospective analysis was performed based on the clinical data of the patients who received treatments in Department of Plastic and Aesthetic ( Burn) Surgery, the Second Xiangya Hospital, Central South University from January 2022 to July 2023 using an external septal retention bionic framework with autologous costal cartilage rhinoplasty. The patients were all treated with a V-shaped incision at the nasal columella, which continued to both sides of the nose to form a bird-shaped incision. During the operation, the sixth or seventh costal cartilage was sculpted to form the nasal columella support grafts (sturt), external nasal septal graft, cap grafts, and shield grafts, in which the nasal column support graft and external nasal septal graft were implanted in a mortise-and-tenon joint structure to form a septum bionic retained external stent in order to lengthen the nasal columellar column and strengthen the septum. A capsular graft was used to shape the tip of the nose and the rectus abdominis fascia was covered to soften the tip of the nose, and the shield grafts were used to fill out the subnasal lobules. A bulb was sculpted, shaped and implanted in the dorsal space to elevate the nasal dorsum. To observe the postoperative results and complications, a postoperative satisfaction survey was completed using the rhinoplasty outcome evaluation (ROE) and the visual analogue scale (VAS) with regular follow-up. Comparison of preoperative and postoperative scale scores was performed using paired samples t-test. Nasal stent stability was assessed by measuring the patients’ preoperative and postoperative nasolabial angle and nasal tip protrusion. The comparison of preoperative and postoperative nasolabial angle was performed using the paired-sample t-test, and the comparison of nasal tip protrusion was performed using the Wilcoxon signed rank-sum test, P<0.05 considered a statistically significant difference. Results:A total of 33 patients were enrolled, including 4 males and 29 females, with average age of 23.8 years(15-42 years). The follow-up period is (14.52 ± 4.72) months (3 to 21 months). Thirty-three patients recovered well after surgery, and no short-term complications such as infection or bleeding occurred. The patients' nasal aesthetic problems such as saddle nose, deviated nasal columella, bilateral asymmetry of the nose, bilateral nasal base depression, and rounded shield of the nasal tip were improved after surgery. Satisfaction survey results: ROE and VAS scores were significantly higher than those before surgery, which were [(17.92±2.56) vs.(12.78±3.14)] and [(8.08±1.66)vs(5.15±1.99)], ( P<0.05), 87.9% (27/33)of the patients were satisfied with the aesthetic and functional outcomes of the nose. Comparisons of nasolabial angle [(87.28±2.58)° vs. (97.64±1.95)°] and tip protrusion [1.88 (1.78, 1.95) cm vs. 2.16(2.01, 2.32) cm] measurements between preoperative and postoperative period of the 33 patients, the differences were statistically significant ( P<0.05). Conclusion:Rhinoplasty for East Asians employs an external septal retention bionic framework to retain the nasal septum. This technique can avoid septal cartilage resorption caused by compression of grafts transplanted in the future, and cause less damage to the anatomy and physiology of the nose. The framework is relatively easy to construct, with a stable and strong stent, and good patient satisfaction. It can achieve a more desirable aesthetic effect of the nose.

AIM:To observe the different effects of three intervention approaches on related biometric parameters in children diagnosed with latent myopia, and to investigate different control effects on children with latent myopia.METHODS:Prospective cohort concurrent controls trials. A total of 60 cases(120 eyes)of children who were initially diagnosed as latent myopia and untreated previously at ophthalmology clinic of the Affiliated Hospital of Chengde Medical University from December 2021 to May 2022 were recruited. They were randomly divided into three groups, with 20 cases(40 eyes)in group A treated with 0.01% Atropine eye drops, 20 cases(40 eyes)in group B treated with vision training with a flip chart, and 20 cases(40 eyes)in group C treated with esculin and digitalis glycosides eye drops. They were followed-up for 12 mo, and the spherical equivalent(SE), axial length(AL), corneal curvature(CC), accommodative facility(AF), and macular retinal thickness of the three groups of children were compared at 6 and 12 mo post-intervention.RESULTS:Significant statistical differences were found in AL, SE and AF of the three groups of children at 6 and 12 mo(all P<0.05), and there were significant differences between 6 and 12 mo after the intervention(all P<0.05). SE and AF in the group B and C were higher than those in the group A(all P<0.05). However, there were no significant differences in CC before and after the intervention(all P>0.05). The retinal thickness of the temporal, nasal, inferior and macular fovea of the outer ring at 6 and 12 mo after intervention in the three groups was significantly different from that at the initial diagnosis(all P<0.05), and there was significant difference between 6 mo and 12 mo after intervention(all P<0.05). There was no significant difference in the retinal thickness of the other macular areas among the three groups before and after intervention(all P>0.05).CONCLUSION:When it comes to preventing and controlling myopia, 0.01% Atropine is more effective than flip chart training and esculin and digitalis glycosides eye drops. Therefore, the administration of 0.01% atropine and the implementation of flip chart training can effectively slow down the advancement of latent myopia.

Objective To investigate the regulatory effects of plasma-derived exosomal microRNA-1306-5p(miR-1306-5p)on inflammation,apoptosis and oxidative stress in intestinal mucosal epithelial cells in sepsis,and to explore the potential mechanisms.Methods Sepsis plasma-derived exosomes and healthy plasma exo-somes were separated and divided into healthy plasma exosomes group and sepsis plasma-derived exosomes group.The exosomes were observed by electron microscopy,the physical parameters of the two groups of exo-somes were analyzed,and the expression of miR-1306-5p in the exosomes was detected.Intestinal mucosal epi-thelial cells were divided into control group,negative control group of miR-1306-5p mimic(mimic-NC group),miR-1306-5p mimic group(mimic group),mimic combined with overexpression of PLK1 empty vector group(mimic-PLK1-EV group),and mimic combined with overexpression of Polo-like kinase 1(PLK1)group(mimic+PLK1-OE group).Real-time fluorescent quantitative PCR was used to detect the mRNA expressions of miR-1306-5p and PLK1 in each group,and protein imprinting was used to detect the expressions of miR-1306-5p target genes PLK1,caspase 3,B lymphoblastoma-2(Bcl-2)and Bcl2-associated X protein(Bax).Dual luciferase reporter gene assay was used to detect the binding effect of miR-1306-5p and PLK1,and flow cytom-etry was used to detect apoptosis.The expressions of tumor necrosis factor-α(TNF-α),interleukin(IL)-1β,IL-6 and IL-8 in the supernatant of cultured cells were detected by enzyme-linked immunosorbent assay.The expressions of reactive oxygen species(ROS),malondialdehyde(MDA),glutathione(GSH)and superoxide dismutase(SOD)were detected by kit method.Results The plasma derived exosomes of sepsis and healthy plasma were ellipsoid in shape,and there was no significant difference in physical parameters(P＞0.05).Compared with the healthy plasma exosomes group,the expression of miR-1306-5p was up-regulated in the plasma derived exosomes of sepsis group(P＜0.05).PLK1 was identified as the target gene of miR-1306-5p by double luciferase reporter method.Compared with mimic-NC group,the expressions of miR-1306-5p,TNF-α,IL-6,IL-8,IL-1β,caspase3,Bax,ROS and MDA were up-regulated,the apoptosis rate was increased,and the expressions of PKL1,Bcl-2,GSH and SOD were down-regulated in mimic group(all P＜0.05).Compared with mimic+PLK1-EV group,the expressions of TNF-α,IL-6,IL-8,IL-1β,caspase3,Bax,ROS,and MDA were significantly down-regulated,the apoptosis rate was decreased,and the expressions of PKL1,Bcl-2,GSH and SOD were up-regulated in mimic+PLK1-OE group(all P＜0.05).Conclusion Plasma derived exosome miR-1306-5p in sepsis promotes inflammation,apoptosis and oxidative stress damage of intestinal mucosal epi-thelial cells by targeting PKL1 inhibition.

Objective To evaluate the risk of bias and reporting quality in randomized controlled trials(RCTs)of the Chinese medicine injection for acute cerebral infarction in the last five years.Methods RCTs literature on Chinese medicine injection in the treatment of acute cerebral infarction was systematically searched in CNKI,Wanfang Data,VIP,China Biology Medicine Database(CBM),PubMed,Embase and Cochrane Library from April 20,2018 to April 20,2023.The risk of bias and reporting quality of included RCTs were evaluated using the Cochrane Risk of Bias Tool(ROB 1.0)and CONSORT-CHM Formulas 2017,respectively.Results A total of 4 301 articles were retrieved,and 408 RCTs were included according to inclusion and exclusion criteria.The ROB evaluation results showed that the the majority of studies were rated as having an unclear risk of bias due to the lack of reporting on allocation concealment,blind method,trial registration information,and funding sources.The evaluation results of CONSORT-CHM Formulas 2017 showed that the number of reported papers of 17 items was greater than or equal to 50%,and the number of reported papers of 25 items was less than 10%,and most of the RCTs did not show the characteristics of TCM syndrome differentiation and treatment.Conclusion The quality of Chinese medicine injection in the treatment of acute cerebral infarction RCTs is generally low.It is recommended that researchers refer to the methodology design of RCTs and international reporting standards,improve the trial design,standardize the trial report,and highlight the characteristics of TCM syndrome differentiation and treatment.

Objective:To investigate the differences between convolutional neural network (CNN) measurements and manual measurements of prosthetic angles and leg length discrepancies after total hip arthroplasty (THA).Methods:Data were collected from 100 patients who underwent unilateral THA at the Department of Orthopaedics, Fourth Medical Center of PLA General Hospital, between January and March 2024. Fifty patients received a ceramic-lined hip prosthesis, and 50 received a polyethylene-lined hip prosthesis. The cohort included 58 males and 42 females, with an average age of 51.6±12.71 years. The left hip was affected in 45 cases, and the right hip in 55 cases. The Attention UNet network was used to segment the prostheses and identify key points, from which the acetabular prosthesis abduction angle, anteversion angle, and leg length discrepancy were calculated. The CNN measurements of anteversion angle, abduction angle, and leg length discrepancy were compared with manual measurements. The consistency between the two methods was evaluated using the Bland-Altman method.Results:CNN measurements of the abduction angle, anteversion angle, and leg length discrepancy for the 100 prostheses were 40.55°±4.76°, 21.5°(19.0°, 27.0°), and 3.6(1.7, 6.8) mm, respectively, while manual measurements were 40.58°±4.93°, 21.0° (17.6°, 23.2°), and 3.0 (2.0, 7.0) mm, respectively. There was a statistically significant difference in anteversion angle between the two methods ( Z=-2.189, P=0.029), but no significant differences in abduction angle or leg length discrepancy ( P>0.05). For the 50 cases with polyethylene-lined prostheses, CNN-measured abduction and anteversion angles were 40.31°±4.70° and 20.0°(18.0°, 22.0°), respectively, while manual measurements were 40.49°±4.92° and 20.0°(17.0°, 21.5°); there were no statistically significant differences ( P>0.05). For the 50 ceramic-lined prostheses, CNN-measured abduction and anteversion angles were 40.79°±4.86° and 26.5°(20.8°, 33.0°), respectively, while manual measurements were 40.68°±4.98° and 20.0°(18.0°, 22.0°), with a significant difference in anteversion angle ( Z=-3.426, P=0.001) but not in abduction angle ( t=0.994, P=0.325). Bland-Altman analysis showed a difference of 0.031°±1.091° for the abduction angle of the 100 prostheses between the two methods, 0.178°±1.296° for the polyethylene-lined prostheses, and -0.116°±0.825° for the ceramic-lined prostheses. For the anteversion angle, the difference was -3.280°±6.920° for the 100 prostheses, -0.002°±1.471° for the polyethylene-lined prostheses, and -6.560°±8.523° for the ceramic-lined prostheses. The difference in leg length discrepancy was -0.101±0.947 mm. Conclusion:CNN measurements of acetabular prosthesis abduction angle, polyethylene-lined prosthesis anteversion angle, and leg length discrepancy after THA showed no significant differences from manual measurements. However, CNN and manual measurements of ceramic-lined prosthesis anteversion angle differed. Bland-Altman analysis indicates that the two methods have good consistency when measuring the abduction angle, the lower limb discrepancy, and the anteversion angle of the polyethylene liner prosthesis.

This article reported a case of successful delivery in a woman with right atrial angiosarcoma and ovarian metastasis. At 31 weeks of gestation, the pregnant woman experienced dyspnea, osphyalgia, nausea, and vomiting. An echocardiogram performed at a local hospital indicated a hypoechoic mass in the right atrium. On December 12, 2023 (32 weeks of gestation), she was transferred to the Third Affiliated Hospital of Guangzhou Medical University. On admission, cardiac ultrasound suggested an irregular slightly high echo in the right atrium, and MRI indicated a malignant tumor. On the day of admission, the patient underwent cardiac exploratory surgery and cesarean section. An enlarged left ovary was found during the surgery, and postoperative pathology confirmed primary right atrial angiosarcoma with left ovarian metastasis. The patient was transferred to the intensive care unit for further treatment. At the request of her family, she was discharged after her condition improved (11 d after the surgery). A male infant who had shallow breathing but did not cry at birth was delivered via cesarean section. He was transferred to the neonatal department for intubation and positive pressure ventilation with a resuscitation bag and was discharged 25 d after birth. The patient was lost to follow-up after discharge.

BACKGROUND: Given the general unavailability, common adverse effects, and complicated administration of tetracycline, the clinical application of classic bismuth quadruple therapy (BQT) is greatly limited. Whether minocycline can replace tetracycline for Helicobacter pylori ( H . pylori ) eradication is unknown. We aimed to compare the eradication rate, safety, and compliance between minocycline- and tetracycline-containing BQT as first-line regimens. METHODS: This randomized controlled trial was conducted on 434 naïve patients with H . pylori infection. The participants were randomly assigned to 14-day minocycline-containing BQT group (bismuth potassium citrate 110 mg q.i.d., esomeprazole 20 mg b.i.d., metronidazole 400 mg q.i.d., and minocycline 100 mg b.i.d.) and tetracycline-containing BQT group (bismuth potassium citrate/esomeprazole/metronidazole with doses same as above and tetracycline 500 mg q.i.d.). Safety and compliance were assessed within 3 days after eradication. Urea breath test was performed at 4-8 weeks after eradication to evaluate outcome. We used a noninferiority test to compare the eradication rates of the two groups. The intergroup differences were evaluated using Pearson chi-squared or Fisher's exact test for categorical variables and Student's t -test for continuous variables. RESULTS: As for the eradication rates of minocycline- and tetracycline-containing BQT, the results of both intention-to-treat (ITT) and per-protocol (PP) analyses showed that the difference rate of lower limit of 95% confidence interval (CI) was >-10.0% (ITT analysis: 181/217 [83.4%] vs . 180/217 [82.9%], with a rate difference of 0.5% [-6.9% to 7.9%]; PP analysis: 177/193 [91.7%] vs . 176/191 [92.1%], with a rate difference of -0.4% [-5.6% to 6.4%]). Except for dizziness more common (35/215 [16.3%] vs . 13/214 [6.1%], P = 0.001) in minocycline-containing therapy groups, the incidences of adverse events (75/215 [34.9%] vs . 88/214 [41.1%]) and compliance (195/215 [90.7%] vs . 192/214 [89.7%]) were similar between the two groups. CONCLUSION: The eradication efficacy of minocycline-containing BQT was noninferior to tetracycline-containing BQT as first-line regimen for H . pylori eradication with similar safety and compliance.

Objective:To observe any effect of electroacupuncture applied to the Jialianquan points in treating post-stroke oropharyngeal dysphagia.Methods:Forty-five stroke survivors with oropharyngeal dysphagia were randomly divided into an electroacupuncture group ( n=15), a neuromuscular electrical stimulation group ( n=15) and a control group ( n=15). All groups received 30 minutes of routine swallowing function training 5 times a week for 3 weeks. The electroacupuncture group was additionally provided with 30 minutes of electroacupuncture applied to the Jialianquan (CV23) points, and the neuromuscular electrical stimulation group instead received 30 minutes of neuromuscular electrical stimulation over the bilateral submental muscles. Videofluoroscopic swallowing studies were performed before and after the 3 weeks of treatment. Standardized swallowing assessment was conducted producing functional oral intake scale ratings, modified barium swallow impairment profiles and the penetration-aspiration scale scores. Surface electromyography was also employed to evaluate submental muscle functioning through measuring the swallowing time, average EMG (AEMG) value and peak amplitude. Results:After the treatment, significant improvement was observed in all of the evaluations with both groups, but the average scores were significantly better in the electroacupuncture and neuromuscular electrical stimulation groups compared with the control group and significantly better in the electroacupuncture group than in the neuromuscular electrical stimulation group.Conclusion:Electroacupuncture at the Jialianquan point can significantly improve the swallowing of stroke survivors with oropharyngeal dysphagia. It is more effective than neuromuscular electric stimulation.
