[Objective] To compare the clinical efficacy and safety of flexible ureteroscope lithotripsy (FURL) combined with flexible vacuum-assisted urethral access sheath (FV-UAS) and traditional UAS in the treatment of 1-2 cm lower renal calyceal stones, so as to provide reference for clinical practice. [Methods] Clinical data of 157 patients with 1-2 cm lower renal calyceal stones treated with FURL during Mar.2021 and Oct.2023 were retrospectively analyzed, including 80 treated with traditional UAS, and 77 with FV-UAS.General and clinical information of the two groups were compared. [Results] The immediate stone-free rate (SFR) (84.4% vs.67.5%, P=0.013) and final SFR (88.3% vs. 75.0%, P=0.032) of the FV-UAS group were significantly higher than those of the traditional UAS group, with significant difference.The incidence of postoperative complications such as fever, renal colic, and perirenal hematoma was significantly higher in the traditional UAS group than in the FV-UAS group (15.0% vs.5.2%, P=0.042). After treatment with anti-infective and analgesic drugs, both groups were improved, and no severe sepsis or septic shock occurred after surgery.The hospitalization expenses of the FV-UAS group were significantly lower than those of the traditional UAS group [ (18 341±1519)yuan vs.(19 152±1826)yuan, P=0.003]. [Conclusion] Compared to the traditional UAS, the combination of FURL and FV-UAS for the 1-2 cm lower renal calyceal stones has a high SFR and low incidence of complications.Patients experience less pain, recover faster and spend less.It's a new treatment option for inferior calyceal calculi.

Objective To investigate the effect and safety of orthokeratology lens on myopia control in adolescents and children with different diopters.Methods Ninety-three patients(171 eyes)with myopia who received orthokeratology lens treatment in the Affiliated Jiangning Hospital of Nanjing Medical University from February to August 2021 were selected for the study.They were divided into a low degree group(88 eyes,-0.5D to-3.0D)and medium degree group(83 eyes,-3.0D to-6.0D)according to the equivalent spherical lens degree.The naked eye distant vision,diopter,optic axis,breakup time of tear film(BUT),corneal endothelial cell count and complications were compared between two groups.Results After 1 year of lens wear,growth of optic axis in low degree group was significantly greater than that in medium degree group(Z=-2.035,P=0.042).After 1 year of lens wear,naked eye distant vision of both groups was significantly higher than that before lens wear(P<0.05),and increase of visual acuity in medium degree group was significantly greater than that in low degree group(P<0.05).The equivalent spherical degree of two groups was significantly lower than that before lens wear(P<0.05),and reduction of equivalent spherical lens degree in medium degree group was significantly greater than that in low degree group(P<0.05).After 1 year of lens wear,BUT in both groups was significantly shorter than that before lens wear,and corneal endothelial cell count was lower than that before lens wear(P<0.05),but there were no significant differences in BUT and corneal endothelial cell count between two groups(P>0.05).There was no statistically significant difference in complication rate between two groups(χ2=2.000,P=0.157).Conclusion Orthokeratology lens has good control effect and safety for adolescents and children with different diopters,and the effect is more prominent for moderate myopia.

[Objective] To explore the efficacy of disposable flexible ureteroscopic lithotripsy (FURL) with flexible vacuum-assisted ureteral access sheath (FV-UAS) in the treatment of 2-3 cm upper urinary tract stones, so as to provide reference for the treatment selection. [Methods] Clinical data of 178 patients with upper urinary tract stones who received FURL or minimally invasive percutaneous nephrolithotomy (MPCNL) at our hospital during Apr. 2022 and Oct. 2023 were retrospectively analyzed. The patients were divided into FV-UAS group (n=90, received FV-UAS combined with diaposable FURL treatment) and MPCNL group (n=88, received MPCNL). The general information, perioperative data, and postoperative stone-free rate (SFR) of the two groups were compared. [Results] All operations were successfully completed. The operation time was significantly longer in the FV-UAS group than in the MPCNL group [(66.5±6.7) min vs. (63.9±7.4) min, P=0.015]. However, the intraoperative hemoglobin reduction [(7.3±3.1)g/L vs.(11.4±5.9)g/L], postoperative hospital stay (P<0.001) [(2.2±0.7)d vs.(5.4±1.3)d], and visual analogue score (VAS) [(2.7±0.9)vs.(5.6±1.1)] were significantly lower in the FV-UAS group than in the MPCNL group (P<0.001). The incidence of persistent gross hematuria was significantly higher in the MPCNL group than in the FV-UAS group (12.5% vs. 3.3%, P=0.023). The FV-UAS group had a similar postoperative immediate (83.3%) and final SFR (95.6%) to those of the MPCNL group (89.8%, 96.6%, P>0.05). [Conclusion] The combination of FURL with FV-UAS for 2-3 cm upper urinary tract stones has a higher SFR and a lower complication rate.Patients experience endurable pain and fast recovery, which is worth promoting and applying in clinical practice.

Objective To compare the effects of antibiotic-loaded bone cement coverage and negative pressure wound therapy (NPWT) on diabetic foot ulcer wound healing. Methods A total of 113 patients with diabetic foot ulcers were selected as study subjects and randomly divided into control group (57 patients receiving NPWT) and experimental group (56 patients receiving antibiotic-loaded bone cement coverage) using the double-color ball randomization method. Both groups underwent routine debridement. The treatment outcomes, positive detection rate of wound bacterial culture, lower limb nerve conduction function (tibial nerve motor conduction velocity, common peroneal nerve sensory conduction velocity), Doppler ultrasound indicators (vessel diameter, blood flow velocity, resistance index, pulsatility index), inflammatory indicators (tumor necrosis factor-α, interleukin-6, high-sensitivity C-reactive protein), and granulation tissue growth were observed and compared between the two groups. Results The effective treatment rate was 85.71% in the experimental group, which was higher than 70.18% in the control group (P < 0.05). Before treatment, there were no statistically significant differences between the two groups in terms of positive detection rate of wound bacterial culture, tibial nerve motor conduction velocity, common peroneal nerve sensory conduction velocity, blood flow velocity, vessel diameter, resistance index, pulsatility index, granulation tissue growth, and serum levels of tumor necrosis factor-α, interleukin-6, and high-sensitivity C-reactive protein (P>0.05). After 3, 7, and 15 days of treatment, the positive detection rate of wound bacterial culture in the experimental group was lower than that in the control group (P < 0.05). After treatment, the tibial nerve motor conduction velocity, common peroneal nerve sensory conduction velocity, vessel diameter, blood flow velocity, resistance index, and pulsatility index in both groups were higher or greater than those before treatment, and those in the experimental group were higher or greater than those in the control group (P < 0.05). After treatment, the granulation tissue area, coverage rate, and granulation tissue growth rate in the experimental group were higher than those in the control group (P < 0.05). After treatment, the serum levels of tumor necrosis factor-α, interleukin-6, and high-sensitivity C-reactive protein in both groups were lower than those before treatment, and those in the experimental group were lower than those in the control group (P < 0.05). Conclusion Compared with NPWT, antibiotic-loaded bone cement coverage has a higher effective treatment rate for diabetic foot ulcers, and provides a more effective local antibacterial environment, thereby promoting wound healing and tissue repair, and simultaneously improving nerve function and vascular status.

Objective: To analyze three different integrated scoring schemes of prostate biopsy and to compare their concordance with the scoring of radical prostatectomy specimens. Methods: A retrospective analysis of 556 patients with radical prostatectomy performed in Nanjing Drum Tower Hospital, Nanjing, China from 2017 to 2020. In these cases, whole organ sections were performed, the pathological data based on biopsy and radical prostatectomy specimens were summarized, and 3 integrated scores of prostate biopsy were calculated, namely the global score, the highest score and score of the largest volume. Results: Among the 556 patients, 104 cases (18.7%) were classified as WHO/ISUP grade group 1, 227 cases (40.8%) as grade group 2 (3+4=7); 143 cases (25.7%) as grade group 3 (4+3=7); 44 cases (7.9%) as grade group 4 (4+4=8) and 38 cases (6.8%) as grade group 5. Among the three comprehensive scoring methods for prostate cancer biopsy, the consistency of global score was the highest (62.4%). In the correlation analysis, the correlation between the scores of radical specimens and the global scores was highest (R=0.730, P<0.01), while the correlations of the scores based on radical specimens with highest scores and scores of the largest volume based on biopsy were insignificant (R=0.719, P<0.01; R=0.631, P<0.01, respectively). Univariate and multivariate analyses showed tPSA group and the three integrated scores of prostate biopsy were statistically correlated with extraglandular invasion, lymph node metastasis, perineural invasion and biochemical recurrence. Elevated global score was an independent prognostic risk factor for extraglandular invasion and biochemical recurrence in patients; increased serum tPSA was an independent prognostic risk factor for extraglandular invasion; increased hjighest score was an independent risk factor for perineural invasion. Conclusions: In this study, among the three different integrated scores, the overall score is most likely corresponded to the radical specimen grade group, but there is difference in various subgroup analyses. Integrated score of prostate biopsy can reflect grade group of radical prostatectomy specimens, thereby providing more clinical information for assisting in optimal patient management and consultation.

BACKGROUND: Ventricular remodeling after acute anterior wall ST-segment elevation myocardial infarction (AAMI) is an important factor in occurrence of heart failure which additionally results in poor prognosis. Therefore, the treatment of ventricular remodeling needs to be further optimized. Compound Danshen Dripping Pills (CDDP), a traditional Chinese medicine, exerts a protective effect on microcirculatory disturbance caused by ischemia-reperfusion injury and attenuates ventricular remodeling after myocardial infarction. OBJECTIVE: This study is designed to evaluate the efficacy and safety of CDDP in improving ventricular remodeling and cardiac function after AAMI on a larger scale. METHODS: This study is a multi-center, randomized, double-blind, placebo-controlled, parallel-group clinical trial. The total of 268 patients with AAMI after primary percutaneous coronary intervention (pPCI) will be randomly assigned 1:1 to the CDDP group (n=134) and control group (n=134) with a follow-up of 48 weeks. Both groups will be treated with standard therapy of ST-segment elevation myocardial infarction (STEMI), with the CDDP group administrating 20 tablets of CDDP before pPCI and 10 tablets 3 times daily after pPCI, and the control group treated with a placebo simultaneously. The primary endpoint is 48-week echocardiographic outcomes including left ventricular ejection fraction (LVEF), left ventricular end-diastolic volume index (LVEDVI), and left ventricular end-systolic volume index (LVESVI). The secondary endpoint includes the change in N terminal pro-B-type natriuretic peptide (NT-proBNP) level, arrhythmias, and cardiovascular events (death, cardiac arrest, or cardiopulmonary resuscitation, rehospitalization due to heart failure or angina pectoris, deterioration of cardiac function, and stroke). Investigators and patients are both blinded to the allocated treatment. DISCUSSION This prospective study will investigate the efficacy and safety of CDDP in improving ventricular remodeling and cardiac function in patients undergoing pPCI for a first AAMI. Patients in the CDDP group will be compared with those in the control group. If certified to be effective, CDDP treatment in AAMI will probably be advised on a larger scale.

Objective: To compare the reproducibility and performance of quantitative metrics between ZOOMit and conventional intravoxel incoherent motion (IVIM) magnetic resonance imaging (MRI) in the diagnosis of early- and mid-stage Sjögren’s syndrome (SS). Materials and Methods: Twenty-two patients (mean age ± standard deviation, 52.0 ± 10.8 years; male:female, 2:20) with early- or mid-stage SS and 20 healthy controls (46.9 ± 14.6 years; male:female, 7:13) were prospectively enrolled in our study.ZOOMit IVIM and conventional IVIM MRI were performed simultaneously in all individuals using a 3T scanner. Quantitative IVIM parameters - including tissue diffusivity (D), pseudodiffusion coefficient (D*), and perfusion fraction (f) - inter- and intra-observer reproducibility in measuring these parameters, and their ability to distinguish patients with SS from healthy individuals were assessed and compared between ZOOMit IVIM and conventional IVIM methods, appropriately. MR gland nodular grade (MRG) was also examined. Results: Inter- and intra-observer reproducibility was better with ZOOMit imaging than with conventional IVIM imaging (ZOOMit vs. conventional, intraclass correlation coefficient of 0.897–0.941 vs. 0.667–0.782 for inter-observer reproducibility and 0.891–0.968 vs. 0.814–0.853 for intra-observer reproducibility). Significant differences in ZOOMit f, ZOOMit D*, conventional D*, and MRG between patients with SS and healthy individuals (all p < 0.05) were observed. ZOOMit D* outperformed conventional D* in diagnosing early- and mid-stage SS (area under receiver operating curve, 0.867 and 0.658, respectively; p = 0.002). The combination of ZOOMit D*, MRG, and ZOOMit f as a new diagnostic index for SS, increased diagnostic area under the curve to 0.961, which was higher than that of any single parameter (all p < 0.01). Conclusion Considering its better reproducibility and performance, ZOOMit IVIM may be preferred over conventional IVIM MRI, and may subsequently improve the ability to diagnose early- and mid-stage SS.
