Objective: This study aimed to elucidate the hand function recovery capacity of degenerative cervical myelopathy (DCM) patients with different severities of hand dexterity impairment. Methods: Hand functional outcome measures such as the 10-second grip and release (10s-G&R) test, modified Japanese Orthopaedic Association (mJOA) upper extremity score and Japanese Orthopaedic Association Cervical Myelopathy Evaluation Questionnaire (JOACMEQ) upper extremity function were collected before surgery and at the 1-year follow-up. A total of 102 DCM patients were categorized into mild, moderate and severe group based on the preoperative 10s-G&R test result. Hand functional parameters were compared across the 3 groups. Multivariate linear regression was conducted to explore predictive factors. Receiver operating characteristic curve analysis was performed to assess the predictive efficacy of the preoperative 10s-G&R test and establish the cutoff value for incomplete recovery of hand dexterity. Results: At the 1-year follow-up, significant improvements were observed in all hand functional parameters across all 3 groups. However, the incomplete recovery rates of the mild, moderate, severe groups were 26.67%, 46.88%, and 57.50%, respectively (p < 0.05). Multivariate regression revealed that preoperative 10s-G&R test result, age, Hoffmann sign, duration of symptom, and mJOA Upper score serve as significant predictors for postoperative 10s-G&R test outcomes. Patients with a preoperative 10s-G&R test < 15 cycles have a 1.9 times higher risk of incomplete recovery of hand function (p = 0.005). Conclusion Most patients, regardless of their preoperative hand function, exhibit potential for improvement in hand dexterity. However, worse initial hand dexterity correlates with poorer outcomes. Surgical treatment is recommended before the 10s-G&R test drops below 15 cycles.

Objective:To sinicize the English version of the rapid eye movement sleep behavior disorder symptom severity scale (RBDSSS) and to evaluate the reliability and validity of the Chinese version of RBDSSS (RBDSSS-C) among Chinese patients with rapid eye movement sleep behavior disorder (RBD).Methods:RBDSSS-C was ultimately formed through translation, back translation and revision according to the Brislin's translation model, including patient version (RBDSSS-PT) and bedpartner version (RBDSSS-BP). A questionnaire survey was conducted among 120 RBD patients to test the reliability and validity of the RBDSSS-C, using Cronbach’s α coefficient, Spearman-Brown coefficient, Spearman correlation analysis, content validity index and factor analysis. The correlation between RBDSSS-C and RBDQ-HK was examined.Results:For the Chinese version of RBDSSS-PT, the Cronbach’s α was 0.795, the split-half reliability was 0.756, and the test-retest reliability was 0.940. Item-level content validity indices (I-CVI) ranged from 0.833 to 1.000, and the scale-level CVI (S-CVI) was 0.937.For the Chinese version of RBDSSS-BP, the Cronbach’s α was 0.712, the split-half reliability was 0.813, and test-retest reliability was 0.950, with both I-CVI and S-CVI at 1.000.The scores of Chinese version of RBDSSS-PT and RBDSSS-BP were both significantly correlated with RBDQ-HK scores ( r=0.638, P<0.001 for RBDSSS-PT; r=0.639, P<0.001 for RBDSSS-BP). Factor analysis confirmed both single-factor structure for RBDSSS-PT and RBDSSS-BP.RBDSSS-PT showed χ2/ df=3.930, CFI=0.954, TLI=0.937, and RMSEA=0.093; RBDSSS-BP showed χ2/ df=8.300, CFI=0.975, TLI=0.966, and RMSEA=0.079. These results indicated adequate model fit. Conclusion:RBDSSS-C has good reliability and validity, and can be used as a reliable and effective tool to evaluate the severity of symptoms in Chinese RBD patients.

An increasing number of studies have shown that there is a close relationship between Alzheimer's disease(AD)and diabetes mellitus(DM).Traditional Chinese medicine holds that"kidney yin deficiency"is the common pathogenesis of these two diseases,while modern medicine believes that their pathogenesis involves abnormal aggregation of amyloid proteins,insulin deficiency and resistance,inflammatory response,oxidative stress,and autophagy,among others.The well-known traditional Chinese medicine formula Liuwei Dihuang Pills plays a significant role in the treatment of these two diseases with the same therapeutic approach.Therefore,this article will explore the connection between Liuwei Dihuang Pills and the treatment of AD and DM from different aspects;analyze the common etiology and pathogenesis of AD and DM,and explain the mechanism of prevention and treatment of Liuwei Dihuang Pills,with the aim of providing new ideas and methods for the integrated traditional and Western medicine prevention and treatment of AD and DM in the future.

Objective:To investigate the diagnostic efficacy of ultrasound in pregnancy associated breast cancer (PABC) under different breast ultrasound background echotextures.Methods:The ultrasonic images of 269 female patients with breast diseases who underwent breast surgery in Fudan University Shanghai Cancer Center from January 2016 to September 2023 and were pregnant or within one year postpartum at the time of onset were retrospectively reviewed. Breast ultrasound background echotextures were classified according to two criteria: the first classification was homogeneous-fat, homogeneous-fibroglandular, and heterogeneous; the other classification was hypoechoic dominated and hyperechoic dominated. The comparison of the diagnostic value of ultrasound in PABC under different backgrounds was conducted by the receiver operating characteristic(ROC) curves.Results:Among 269 patients, 67 patients(24.91%)were during pregnancy and 202 patients(75.09%) were within one year postpartum. Pathologically, 47 patients (17.47%) were confirmed as benign, 222 patients (82.53%) were malignant. According to the first classification, 138 patients were homogeneous-fibroglandular and 131 patients were heterogeneous, with the diagnostic sensitivity of ultrasound in PABC were 88.70% and 59.81% respectively, and the specificity were 91.30% and 83.33% respectively, the areas under the ROC curves were 0.940 and 0.826 respectively ( P=0.022). According to the second classification, 119 were hypoechoic dominated and 150 patients were hyperechoic dominated, the sensitivity were 60.21% and 85.27% respectively, the specificity 84.62% and 90.48% respectively, the areas under the ROC curves were 0.826 and 0.925 ( P=0.042). Conclusions:The heterogeneous background echotextures of the breast may cause decrease of the diagnostic efficiency of ultrasound in PABC, and hypoechoic dominated background was more unfavorable for the diagnosis of PABC compared to the hyperechoic dominated background.
