Objective:To observe any effect of functional magnetic stimulation (FMS) of the sacral 3 nerve root on relieving urine retention after a spinal cord injury.Methods:Forty-four patients with neurogenic bladder disorders after a spinal cord injury were divided at random into a 5Hz group ( n=14), a 20Hz group ( n=15), and a sham stimulation group ( n=15). In addition to conventional bladder control training, the 5Hz and 20Hz groups were given 20 minutes of FMS of the sacral 3 nerve root at the appropriate frequency five days a week for 4 weeks. The sham stimulation group was not given any stimulation. A detailed urination diary was kept during the treatment, and before and after the 4 weeks, everyone′s bladder pressure volume was assessed and an electromyogram was recorded. Results:After the treatment those in the 5Hz and 20Hz groups had improved significantly in terms of average bladder capacity, bladder pressure, residual urine volume, daily number of urethral catheterizations, daily micturition frequency, single urine output, H-reflex latency, and the amplitude and incubation period of the F wave. Those in the sham stimulation group showed no consistent improvement in any of these indicators. Moreover, the average residual urine volume, daily urination frequency and H-reflex latency and amplitude of the 20Hz group were significantly better than those of the 5Hz group.Conclusions:Magnetic stimulation of the S3 nerve roots can effectively improve the urination of persons with neurogenic bladder disorders after a spinal cord injury. The preferred frequency is 20Hz.

PURPOSE: . The aim of this study was to evaluate the reliability of implant stability measuring devices depending on the location of the implant and the position of the patient. MATERIALS AND METHODS: . Six implants were installed in different dentate sextants of six artificial bone models. Implant stability was measured in three conditions of the bone model (without mounting on a phantom head, mounted on a phantom head in supine position, and mounted on a phantom head in upright position). A resonance frequency analysis device (Osstell) and two damping capacity analysis devices (Periotest and Anycheck) were used to measure implant stability. The values measured outside the phantom head were treated as controls, and the values inside the phantom head were compared using an independent t-test. RESULTS: . Osstell showed different results in two of the six divisions in both the supine and upright positions compared to outside of the mouth (P < .05). Periotest showed different results in all six parts in the supine position and in five parts in the upright position compared to outside of the mouth (P < .05). While Anycheck showed different results in five areas in the supine position compared to outside of the mouth, it showed different results in only one area in the upright position (P < .05). CONCLUSION . In the difficult implant position for the operator to access, the implant stability measuring devices show less reliability. The accessibility of implant is greatly affected in the order of Osstell, Anycheck, and Periotest. [J Adv Prosthodont 2023;15:126-35]

Pruni Semen,the seed of several unique Prunus plants,is a traditional purgative herbal material.To determine the authentic sources of Pruni Semen,46 samples from four species were collected and analyzed.Ten compounds including multiflorin A(Mul A),a notable purative compound,were isolated and identified by chemical separation and nuclear magnetic resonance spectroscopy.Seventy-six communal components were identified by ultra-high performance liquid chromatography with linear ion trap-quadrupole Orbitrap mass spectrometry,and acetyl flavonoid glycosides were recognized as characteristic constituents.The flavonoids were distributed in the seed coat and cyanogenic glycosides in the kernel.Based on this,methods for identifying Pruni Semen from different sources were established using chemical fingerprinting,quantitative analysis of the eight principal compounds,hierarchical cluster analysis,principal component analysis,and orthogonal partial least squares discriminant analysis.The results showed that the samples were divided into two categories:one is the small seeds from Prunus humilis(Ph)and Prunus japonica(Pj),and the other is the big seeds from Prunus pedunculata(Pp)and Prunus triloba(Pt).The average content of Mul A was 3.02.6.93,0.40,and 0.29 mg/g,while the average content of amygdalin was 18.5,17.7,31.5,and 30.9 mg/g in Ph,Pj,Pp,and Pt,respectively.All the above information suggests that small seeds might be superior sources of Pruni Semen.This is the first comprehensive report on the identification of chemical components in Pruni Semen from different species.

Objective:To investigate the predictive value of systemic inflammatory response index (SIRI), systemic immune-inflammation index (SII), and CT perfusion imaging (CTP) parameters for early neurological deterioration (END) in patients with mild stroke duo to anterior circulation large vessel occlusion.Methods:Patients with minor stroke duo to anterior circulation large vessel occlusion admitted to the First People's Hospital of Suqian from November 2021 to December 2023 were included. Minor stroke was defined as a baseline National Institutes of Health Stroke Scale (NIHSS) score ≤ 5, and END was defined as an increase of ≥ 4 in NIHSS score within 24 hours of admission compared to the baseline. SIRI and SII were calculated based on the findings of blood routine examination. According to CTP at admission, the cerebral blood volume (CBV) index, infarct core volume, and early infarct growth rate (EIGR) were obtained. Multivariate logistic regression analysis was used to determine the independent risk factors for END. Receiver operating characteristic (ROC) curve was used to evaluate the predictive value of each predictor on END. Results:A total of 132 patients were included, with 85 males (64.4%) and a median age of 68 years (interquartile range, 58-77 years). Thirty-nine patients (29.5%) experienced END. The baseline NIHSS score, fasting blood glucose, neutrophil count, lymphocyte count, SIRI, SII, infarct core volume, and EIGR in the END group were significantly higher than those in the non-END group, while the CBV index was significantly lower than that in the non-END group (all P<0.05). Multivariate logistic regression analysis showed that SIRI (odds ratio [ OR] 3.672, 95% confidence interval[ CI] 1.838-6.326; P<0.001), SII ( OR 4.824, 95% CI 2.057-7.135; P<0.001), CBV index ( OR 0.968, 95% CI 0.947-0.986; P<0.001), and EIGR ( OR 2.527, 95% CI 1.918-3.589; P<0.001) were the independent predictive factors of END. ROC curve analysis showed that the area under the curves of SIRI, SII, CBV index, and EIGR for predicting END were 0.780 (95% CI 0.692-0.863), 0.798 (95% CI 0.709-0.888), 0.775 (95% CI 0.697-0.853), and 0.772 (95% CI 0.732-0.829), respectively. Conclusion:SIRI, SII, CBV index, and EIGR are the independent predictive factors of END in patients with minor stroke duo to anterior circulation large vessel occlusion, and have certain predictive value for END.

Robotic surgical systems are gradually being used in minimally invasive surgery with their advantages of high-definition magnified 3D images, stable surgical field and flexible operation. The change of surgical approach and the narrow operating space in robotic thyroid surgery have made it more difficult to identify and protect the laryngeal nerve, and the application of nerve monitoring has been limited. Many researchers have attempted to improve the monitoring equipment and probe placement to make intraoperative neuromonitoring techniques work well in robotic thyroid surgery. In this paper, we seek effective ways to protect the laryngeal nerve in robotic thyroid surgery, and lay the foundation for a more minimally invasive and standardized development of this technology.

Inclusion criteria: (1) hospitalized patients receiving fibrocolonoscopy; (2) adenocarcinoma and mucinous adenocarcinoma diagnosed by pathology; (3) with preoperative cTNM clinical staging; (4) colorectal cancer patients undergoing surgical treatment; (5) with postoperative pTNM staging; (6) no smoking or drinking habits. Exclusion criteria: (1) familial adenomatous polyposis (FAP); (2) Lynch syndrome; (3) carcinoma of anal canal and perianal carcinoma; (4) multiple primary cancer; (5) with serious cardiocerebrovascular diseases or multiple organ failure. Clinicopathlogical data of 32 DCRC patients who were diagnosed and treated in Peking University Shougang Hospital from December 2017 to December 2018 were retrospectively collected and analyzed. Forty nondiabetic colorectal cancer (CRC) patients during the same period were selected as control group according to the sex ratio and the age difference less than 5 years. Student′s t test and χ2 test were used to compare the difference between the two groups in baseline clinicopathological data, clinical test results, tumor markers and infiltration status of T cells in tumor immune microenvironment. Results Among 32 DCRC patients, 24 were males and 8 were females with a mean age of (63.0±1.7) years; among 40 CRC patients, 30 were males and 10 were females with a mean age of (60.5 ± 1.6) years. The duration of diabetes mellitus in DCRC patients (from the diagnosis of diabetes mellitus to the diagnosis of colorectal cancer) was (9.2±1.3) years. The body mass index (BMI) of DCRC group was significantly higher than that of CRC group [(24.8±0.6) kg/m2 vs. (23.2±0.4) kg/m2, t=2.372, P=0.020]. There were no significant differences in other baseline data (sex, age, primary site of tumor, R0 resection rate, pathological stage, pathological type, differentiation degree of tumor, preoperative intestinal obstruction) between the two groups (all P>0.05). Serum triglyceride level in DCRC group was higher than that in CRC group [(2.1 ± 0.2) mmol/L vs. (1.5 ± 0.1) mmol/L, t=3.085, P=0.003], while hemoglobin [(120.3±5.2) g/L vs. (132.7±2.8) g/L, t=-2.224, P=0.029], anti? thrombin III [(94.2±3.7)% vs. (103.5±2.4)%, t=-2.197, P=0.031], and red blood cell count [(4.2±0.1)×1012/L vs. (4.5±0.1)×1012L, t=-2.055, P=0.044] were all lower than those in CRC group. The preoperative carcinoembryonic antigen (CEA) level in DCRC group was higher than that in CRC group [(50.3±21.8) μg/L vs. (5.6±1.0) μg/L, t=2.339, P=0.022]. There were no significant differences in preoperative levels of other four tumor molecular markers (CA199, CA242, CA724 and CA125) between the two groups (all P>0.05). The expression of Foxp3 [specific markers of CD4+, CD25+ regulatory T cells (Treg)] in DCRC group was higher than that in CRC group [(82.7±6.2) cell/ HPF vs. (62.6±4.9) cell/HPF, t=2.586, P=0.012]. There were no significant differences in the infiltration of CD4, CD8, PD?1 and PD?L1 positive cells between two groups (all P>0.05).Conclusions The average diabetic history of DCRC patients is nearly 10 years. They have higher BMI and serum CEA level, and more Treg cell infiltration in the tumor. Close attention should be paid to these patients in clinical practice.

Eclipta prostrata L.has been used in traditional medicine and known for its liver-protective properties for centuries.Wedelolactone(WEL)and demethylwedelolactone(DWEL)are the major coumarins found in E.prostrata L.However,the comprehensive characterization of these two compounds on non-alcoholic fatty liver disease(NAFLD)still remains to be explored.Utilizing a well-established zebrafish model of thioacetamide(TAA)-induced liver injury,the present study sought to investigate the impacts and mechanisms of WEL and DWEL on NAFLD through integrative spatial metabolomics with liver-specific transcriptomics analysis.Our results showed that WEL and DWEL significantly improved liver function and reduced the accumulation of fat in the liver.The biodistributions and metabolism of these two compounds in whole-body zebrafish were successfully mapped,and the discriminatory endogenous metabolites reversely regulated by WEL and DWEL treatments were also characterized.Based on spatial metabolomics and transcriptomics,we identified that steroid biosynthesis and fatty acid metabolism are mainly involved in the hepatoprotective effects of WEL instead of DWEL.Our study unveils the distinct mechanism of WEL and DWEL in ameliorating NAFLD,and presents a"multi-omics"platform of spatial metabolomics and liver-specific transcriptomics to develop highly effective compounds for further improved therapy.
