Objective:To apply statistical process control (SPC) techniques to the quality assurance of non-normal radiotherapy plans through Johnson transformation, establishing patient-specific tolerance and action limits based on treatment sites and dose/distance assessment criteria, thereby enhancing the intensity-modulated radiation therapy (IMRT) verification accuracy and dose delivery precision.Methods:In this study, 951 gamma analysis data of patient-specific quality assurance (PSQA) executed on the Halcyon accelerator platform were selected and categorized into six groups based on treatment sites, including brain (102 cases), head and neck (100 cases), breast (229 cases), lung (154 cases), esophagus (223 cases), and pelvic (143 cases) groups. The six groups of data were statistically analyzed through Anderson-Darling normality tests ( α = 0.05) using Minitab 21 software. Non-normal data were transformed into normal data through Johnson transformation and then were used to establish treatment site-specific tolerance and action limits, which were compared with the Shewhart control charts based on normal distributions. Results:The PSQA result of the six groups all exhibited non-normal distributions ( P < 0.05). Through Johnson transformation, the tolerance and action limits for the head and neck, breast, lung, esophagus, and pelvic areas under the 3%/2 mm criterion ranged from 95.13% to 96.16% and 94.19% to 95.91%, respectively. In contrast, the tolerance and action limits ranged from 91.15% to 94.86% and 89.94% to 94.78% under the 2%/2 mm criterion. Directly applying Shewhart control charts without normality assumptions yielded higher tolerance limits compared to the application of Johnson transformation, increasing the false positive rate in the non-normal PSQA process. Conclusions:Applying the SPC techniques directly to a non-normal process can lead to an increased false alarm rate and wrong process interpretation. The SPC techniques combined with Johnson transformation enable more effective monitoring of a non-normal PSQA process, facilitating timely identification of potential factors that may lead to an out-of-control process based on the treatment site-specific limits.

Objective:To evaluate the music perception ability and appraisal status of cochlear implant adult users, then to compare those with normal-hearing subjects.Methods:The Iowa Musical Background and Appreciation Questionnaire (IMBAQ) was conducted to evaluate 20 cases of post-lingual deafness cochlear implant recipients (9 males, 11 females) aged 12-61(mean=28.8 yrs). Those music perception abilities were tested via Music Perceptional Evaluation Platform. Two kinds of tone(C#3, C#5)were carried out in the music perception test, including the Just Noticeable Difference (JND) Test, the Pitch-Direction Discrimination (PDD) Test and the Melody Contour Identification (MCI) Test. Meanwhile, the timbre identification tests were received by both normal hearing and cochlear implant patients.Results:The total outcomes of cochlear implant recipients were inferior to the normal hearing subjects ( P<0.05). Both of the thresholds of JND ( P=0.001) and PDD ( P<0.001) had a significant difference, while comparing the two frequency values (C#3 and C#5) in cochlear implant adult users. IMBAQ results indicated the lower post-implantation music appreciation and engagement compared to pre-deafness levels. The longer duration of formal music training was positively correlated with better music perception performance in CI recipients. Conclusions:There still has a big gap between the cochlear implant group and normal hearing group in the music perception test. And different frequency value causes effect on the result of cochlear implant patient group.

Objective:To establish and validate a nomogram model for early prediction of the risk of acute pancreatitis (AP) progressing to severe acute pancreatitis (SAP).Methods:CT signs and clinical laboratory parameters of 361 AP patients admitted to our Hospital from January 2016 to July 2022 were retrospectively collected. There were 221 males (61.2%) and 140 females (38.8%). According to the Atlantic score, all patients were divided into the SAP group (64 cases) and the non-SAP (NSAP) group (297 cases). Univariate analysis was used to screen out variables with statistically significant differences. Multivariate Logistic regression analysis was used to screen out the independent risk factors of SAP, and finally a nomogram prediction model was established. Receiver operating characteristic (ROC) curve, calibration curve and decision curve (DCA) were used to evaluate the predictive efficacy, accuracy and clinical practicability of the model, and Bootstrap method was used to verify the model internally.Results:Univariate analysis and multivariate Logistic regression analysis showed that pleural effusion ( OR=7.353, 95% CI: 3.344-16.170), posterior pararenal space (PPS) involvement ( OR=3.149, 95% CI: 1.314-7.527), serum creatinine concentration (Cr) ( OR=1.027, 95% CI: 1.017-1.038) and serum calcium concentration (Ca 2+) ( OR=0.038, 95% CI: 0.009-0.166) were independent risk factors for SAP ( P<0.05). A Nomogram model was established based on these four factors. The area under the ROC curve (AUC) of this model was 0.905 (95% CI: 0.869-0.933), indicating high predictive efficiency. Internal verification showed that the model had good accuracy in predicting SAP, and C-index was 0.90. DCA analysis showed that the model had high clinical practicability. Conclusions:The Nomogram model combining pleural effusion, PPS involvement, Cr and Ca 2+ had a good effect on early prediction of SAP, which could provide a new reference tool for clinical diagnosis and treatment.

Objective:To compare modified load-sharing rip-stop (mLSRS) technique with suture bridge (SB) for repair of massive rotator cuff tears.Methods:A retrospective analysis was conducted of the 68 patients who had been treated for massive rotator cuff tears from January 2017 to June 2019 at Department of Orthopedics, Dongyang People's Hospital. They were 26 males and 42 females, aged (63.4±1.0) years (from 45 to 84 years), with 56 right and 12 left sides affected. Of them, 32 were treated by mLSRS and 36 by double-line SB. The 2 groups were compared in terms of visual analog scale (VAS), Constant-Murley scoring, University of California Los Angeles (UCLA) scoring and American Shoulder and Elbow Surgeons (ASES) scoring at the final follow-ups, and Sugaya ultrasonic evaluation of the repair integrity at postoperative 12 months.Results:There was no statistically significant difference in preoperative general data between the 2 groups, showing they were comparable ( P>0.05). Operations were successful in all patients who were followed up for 13 to 44 months (average, 19.7 months). No patient suffered from such complications as joint infection or anchor withdrawal. At the final follow-up, the mLSRS group scored respectively 0.9±0.6, 85.3±4.8, 33.1±1.0 and 86.4±5.0 in VAS, Constant-Murley, UCLA and ASES scores, significantly improved than their preoperative values (7.2±0.8, 47.0±3.1, 15.8±3.0 and 48.5±4.5) ( P<0.05); the SB group scored respectively 1.1±0.6, 86.6±3.4, 33.2±1.1 and 86.9±4.6 in the above indicators, also significantly improved than their preoperative values (7.3±0.7, 46.5±4.7, 14.4±2.7 and 48.8±4.3) ( P<0.05); there were no significant differences between the 2 groups in preoperative or postoperative values ( P> 0.05). The Sugaya ultrasonic evaluation showed no significant difference in rotator cuff healing between the 2 groups at postoperative 12 months ( P>0.05); according to the positions of re-tears, the SB group had significantly more type Ⅱ re-tears (20%, 2/10) than the mLSRS group (0, 0/4) ( P<0.05). Conclusion:Although both mLSRS and SB techniques can achieve satisfactory and comparable clinical outcomes in arthroscopic repair of massive rotator cuff tears, mLSRS may lead to fewer postoperative type Ⅱ re-tears than SB.

ObjectiveTo explore the related factors of troublemaking behaviors among patients with mental disorders induced by amphetamine-type stimulants （ATS）， and to provide references for the formulation of relevant intervention measures for ATS-induced mental disorders. MethodsA total of 105 patients who met the diagnostic criteria of International Classification of Diseases， tenth edition （ICD-10） for ATS-induced mental disorders were included， and classified into troublemaking group and non-troublemaking group. The general demographic data and clinical data of the selected individuals were collected， and all patients were assessed using Social Support Rating Scale （SSRS）. Then univariate analysis and multivariate Logistic regression model were used to screen the related factors of troublemaking behaviors. ResultsThe scores of SSRS， objective support dimension and social support utilization dimension were significantly lower in troublemaking group than those in non-troublemaking group， with statistical differences ［（24.10±6.59） vs. （28.94±5.59）， t=3.364， P=0.001； （5.50±1.96） vs. （8.20±2.13）， t=5.183， P<0.01； （4.60±2.26） vs. （6.28±1.90）， t=3.435， P=0.001］. Multivariate Logistic regression analysis showed that male （OR=6.061， P=0.014） was a risk factor， while high social support level （OR=0.873， P=0.018） was the protective factor for troublemaking behaviors among patients with ATS-induced mental disorders. ConclusionPatients with ATS-induced mental disorders of the males and with low social support level are at high risk of troublemaking behaviors.
