OBJECTIVE: To investigate the effect of femoral condyle sliding osteotomy (FCSO) on the flexion gap and external rotation of the prosthesis in balancing coronal instability during initial total knee arthroplasty (TKA). METHODS: Between November 2021 and October 2024, FCSO technique was applied to balance the coronal medial and lateral spaces during initial TKA in 3 patients, including medial condyle sliding osteotomy (MCSO) and lateral condyle sliding osteotomy (LCSO). There were 1 male and 2 females with the age of 81, 68, and 68 years old. The affected knee has varus or valgus deformity, with tibia-femoral angles of 169.7°, 203.3°, and 162.2°, respectively. The hip-knee-ankle angle (HKA), range of motion (ROM), knee society scoring system (KSS), and pain visual analogue scale (VAS) score were used to evaluate joint function and pain relief. Based on model bone, the thickness and bone bed area of the medial and lateral femoral condyle osteotomy blocks in FCSO were measured. During TKA in 12 patients, the range of osteotomy block movement was evaluated. By simplifying the upward and forward movement of the osteotomy block into a geometric model, the impact of movement on the flexion gap and external rotation of the prosthesis was calculated. RESULTS: After application of FCSO during TKA, the limb alignment and medial and lateral balance at extension and flexion positions were restored in 3 patients. Three patients were followed up 23, 11, and 3 months, respectively. Postoperative HKA, pain VAS score, KSS score, and ROM all showed significant improvement compared to preoperative levels. The maximum thickness of osteotomy blocks by MCSO and LCSO was 17 and 12 mm, respectively. The simple upward movement of the osteotomy block mainly affected the extension gap, and had little effect on the flexion gap and external rotation of the prosthesis. Moving the osteotomy block forward at the same time had a significant impact on the flexion gap and external rotation of the prosthesis, especially on LCSO. Mild forward movement leaded to a decrease in external rotation of more than 3°, which had a serious impact on the patellar trajectory. CONCLUSION FCSO can effectively solve the problem of imbalance between the medial and lateral spaces during initial TKA, avoiding knee joint instability caused by excessive loosening and limiting the use of constrained condylar prosthesis. The distance for the downward movement of the osteotomy block in MCSO and LCSO was 3-5 mm and 6-8 mm, respectively, with 10-15 mm of space for forward movement and almost no space for backward movement. For MCSO, the upward and forward movement of the osteotomy block will increase the external rotation of the prosthesis, which is beneficial for improving the patellar trajectory and suitable for valgus knee. LCSO is suitable for varus knee, and the osteotomy block only slides vertically up and down without moving forward and backward.

Objective:To explore the influencing factors for compliance to colonoscopy screening for colorectal cancer in outpatients.Methods:Patients aged 40-74 years who visited the outpatient gastroenterology department of 7 tertiary hospitals in 7 regions of Xinjiang from January 2022 to June 2022 were enrolled. Recommendations for colonoscopy screening were made according to the patient's medical conditions, and the questionnaire was used to collect information. The Chi-square test was used to compare the differences of compliant and non-compliant patients. Multivariate logistic regression was used to analyze the influencing factors of compliance to colonoscopy screening.Results:A total of 463 valid questionnaires were obtained from 7 centers, in which, 427 outpatients (92.2%) followed the recommendation for colonoscopy screening, and 36 (7.8%) did not. Chi-square test results showed that there were statistically significant differences between the two groups in gender, age, education, subjective cognition of intestinal polyps, personal history of colorectal polyps, family history of colorectal cancer, family history of colorectal polyps, abdominal pain or distension, and defecation habit or stool changes ( P<0.05). The results of multivariate regression analysis showed that the screening compliance of patients aged 40-49 years ( P=0.005, OR=0.141, 95% CI: 0.036-0.549) and 50-59 years ( P=0.039, OR=0.257, 95% CI: 0.071-0.932) was lower than that of patients aged 60-74 years. The screening compliance of patients with high school education ( P=0.011, OR=3.121, 95% CI: 1.304-7.473) and college education or above ( P=0.016, OR=3.544, 95% CI: 1.270-9.890) was higher than those with primary school education and below. Patients with personal history of colorectal polyps ( P=0.015, OR=12.288, 95% CI: 1.629-92.719), family history of colorectal cancer ( P=0.038, OR=8.506, 95% CI: 1.124-64.351) and changes in defecation habit or stool trait ( P=0.039, OR=4.794, 95% CI: 1.085-21.192) also had higher compliance. Conclusion:Age, educational level, personal history of colorectal polyps, and family history of colorectal cancer are related to colonoscopy screening compliance in outpatients of 7 tertiary hospitals in 7 regions of Xinjiang. The independent risk factors affecting compliance to colorectal cancer screening in outpatients are age of 40-59 years, lower educational level, no previous history of polyps or family history of colorectal cancer, and no defecation habit or stool changes.

The biological clock(also known as the circadian rhythm)is the fundamental reliance for all organisms on Earth to adapt and survive in the Earth's rotation environment.Circadian rhythm is the most basic regulatory mechanism of life activities,and plays a key role in maintaining normal physiological and biochemical homeostasis,disease occurrence and treatment.Recent studies have shown that the biologi-cal clock plays an important role in the development of oral tissues and in the occurrence and treatment of oral diseases.Since there is cur-rently no guiding literature on the research methods of biological clock in stomatology,researchers mainly conduct research based on pub-lished references,which has led to controversy about the research methods of biological clock in stomatology,and there are many confusions about how to rationally apply the research methods of circadia rhythms.In view of this,this expert consensus summarizes the characteristics of the biological clock and analyzes the shortcomings of the current biological clock research in stomatology,and organizes relevant experts to summarize and recommend 10 principles as a reference for the rational implementation of the biological clock in stomatology research.

Objective To investigate the application value of the MHSeqTyper47 kit in kinship identification.Methods Multiplexed amplification and library preparation were performed for DNA samples from 113 related individuals by using the MHSeqTyper47 kit.The libraries were sequenced on a MiSeq FGx sequencer,and the data were analyzed using MHTyper for microhaplotype genotyping.The kinship indexes were calculated to evaluate the application efficiency of this kit in kinship identification and compared with those of the GlobalFilerTM kit.Results For the MHSeqTyper47 kit,the CPI values in trio identification were 1.43× 1011～6.15×1018.The CPI values in duo identification were 1.02× 105～1.53× 1013.The CFSI values in full sibling identification were 7.73×101～2.59×1016.Trios,duos and full siblings could be completely distinguished from unrelated pairs.The combined efficiency of these two kits in 2nd-degree kinship identification was 0.466 2.Conclusion The application value of MHSeqTyper47 kit is relatively higher in the identification of lst-degree kinships.If jointly used with the GlobalFilerrM kit,2nd-degree kinship identification could be achieved in some cases.

Background and Objectives: Real-world clinical data, outside of clinical trials and expert centers, on adverse events related to the use of SyncCardia total artificial heart (TAH) remain limited. We aim to analyze adverse events related to the use of SynCardia TAH reported to the Food and Drug Administration (FDA)’s Manufacturers and User Defined Experience (MAUDE) database. Methods: We reviewed the FDA’s MAUDE database for any adverse events involving the use of SynCardia TAH from 1/01/2012 to 9/30/2020. All the events were independently reviewed by three physicians. Results: A total of 1,512 adverse events were identified in 453 “injury and death” reports in the MAUDE database. The most common adverse events reported were infection (20.2%) and device malfunction (20.1%). These were followed by bleeding events (16.5%), respiratory failure (10.1%), cerebrovascular accident (CVA)/other neurological dysfunction (8.7%), renal dysfunction (7.5%), hepatic dysfunction (2.2%), thromboembolic events (1.8%), pericardial effusion (1.8%), and hemolysis (1%). Death was reported in 49.4% of all the reported cases (n=224/453).The most common cause of death was multiorgan failure (n=73, 32.6%), followed by CVA/other non-specific neurological dysfunction (n=44, 19.7%), sepsis (n=24, 10.7%), withdrawal of support (n=20, 8.9%), device malfunction (n=11, 4.9%), bleeding (n=7, 3.1%), respiratory failure (n=7, 3.1%), gastrointestinal disorder (n=6, 2.7%), and cardiomyopathy (n=3, 1.3%). Conclusions Infection was the most common adverse event following the implantation of TAH. Most of the deaths reported were due to multiorgan failure. Early recognition and management of any possible adverse events after the TAH implantation are essential to improve the procedural outcome and patient survival.

Reduced protein S activity is one of the high-risk factors for venous thromboembolism.Hereditary protein S deficiency is an autosomal dominant disorder caused by mutations in the PROS1 gene.We reported a female patient with a mutation of c.292 G>T in exon 3 of the PROS1 gene,which was identified by sequencing.The genealogical analysis revealed that the mutation probably originated from the patient's mother.After searching against the PROS1 gene mutation database and the relevant literature,we confirmed that this mutation was reported for the first time internationally.

We reported a 26-year-old male who was diagnosed with apical hypertrophic cardiomyopathy with left ventricular aneurysm. The location of the hypertrophic myocardium and the extent of resection were accurately assessed preoperatively using 3D modeling and printing technology. Myectomy was performed via transapical approach, and the intraoperative exploration was consistent with the description of the preoperative 3D modeling. The patient underwent the surgery successfully without any complications during the hospitalization, and the cardiopulmonary bypass time was 117 min, the aortic cross-clamping time was 57 min, and the hospital stay time was 7 d. The postoperative echocardiography demonstrated left ventricular cavity flow patency. This case provides a reference for the management of patients with apical hypertrophic cardiomyopathy.

The extracellular domain (p75ECD) of p75 neurotrophin receptor (p75NTR) antagonizes Aβ neurotoxicity and promotes Aβ clearance in Alzheimer's disease (AD). The impaired shedding of p75ECD is a key pathological process in AD, but its regulatory mechanism is largely unknown. This study was designed to investigate the presence and alterations of naturally-occurring autoantibodies against p75ECD (p75ECD-NAbs) in AD patients and their effects on AD pathology. We found that the cerebrospinal fluid (CSF) level of p75ECD-NAbs was increased in AD, and negatively associated with the CSF levels of p75ECD. Transgenic AD mice actively immunized with p75ECD showed a lower level of p75ECD and more severe AD pathology in the brain, as well as worse cognitive functions than the control groups, which were immunized with Re-p75ECD (the reverse sequence of p75ECD) and phosphate-buffered saline, respectively. These findings demonstrate the impact of p75ECD-NAbs on p75NTR/p75ECD imbalance, providing a novel insight into the role of autoimmunity and p75NTR in AD.

BACKGROUND: Butylphthalide (NBP) and edaravone (EDV) injection are common acute ischemic stroke medications in China, but there is a lack of large real-world safety studies on them. This study aimed to determine the incidence of adverse events, detect relevant safety signals, and assess the risk factors associated with these medications in real-world populations. METHODS: In this study, data of acute ischemic stroke patients were extracted from the electronic medical record database of six tertiary hospitals between January 2019 and August 2021. Baseline confounders were eliminated using propensity score matching. The drugs' safety was estimated by comparing the results of 24 laboratory tests standards on liver function, kidney function, lipid level, and coagulation function. The drugs' relative risk was estimated by logistic regression. A third group with patients who did not receive NBP or EDV was constructed as a reference. Prescription sequence symmetry analysis was used to evaluate the associations between adverse events and NBP and EDV, respectively. RESULTS: 81,292 patients were included in this study. After propensity score matching, the NBP, EDV, and third groups with 727 patients in each group. Among the 15 test items, the incidence of adverse events was lower in the NBP group than in the EDV group, and the differences were statistically significant. The multivariate logistic regression equation revealed that NBP injection was not a promoting factor for abnormal laboratory test results, whereas EDV had statistically significant effects on aspartate transaminase, low-density lipoprotein cholesterol and total cholesterol. Prescription sequence symmetry analysis showed that NBP had a weak correlation with abnormal platelet count. EDV had a positive signal associated with abnormal results in gamma-glutamyl transferase, alanine aminotransferase, aspartate aminotransferase, prothrombin time, and platelet count. CONCLUSIONS In a large real-world population, NBP has a lower incidence of adverse events and a better safety profile than EDV or other usual medications.
