Objective To investigate the level of coagulation factor Ⅺ(FⅪ)in patients with venous thrombosis of lower limbs and its correlation with recurrence risk.Methods A total of 220 pa-tients with deep vein thrombosis(DVT)admitted in our hospital from February 2018 to February 2019 were enrolled as the study group,and another 50 healthy individuals taking physical exami-nation during same period served as the control group.After a 3 years followed,the study group ultimately included 197 cases,according to the results of restricted cubic spline(RCS),the study group was divided into low(FⅪ＜10.3 U/L,94 cases),medium-(10.3-12.1 U/L,52 cases)and high-level groups(＞12.1 U/L,51 cases).The plasma level of FⅪ was detected in the study group 1 month after the end of anticoagulant therapy,and the results were compared with those of the control group during physical examination.Cox model was used to analyze the influence of FⅪ on the recurrence of DVT,and RCS was employed to analyze the relationship between DVT recur-rence and FⅪ level.Kaplan-Meier curve was plotted to analyze the recurrence risk of DVT with different FⅪ levels.The patients from the study group were followed up for 3 years.Results The FⅪ level was significantly higher in the study group than the control group(P＜0.05).During fol-low-up period,33 patients(16.75％)had DVT recurrence.The Cox model analysis after adjust-ment of sex and age showed that FⅪ level was a risk factor for DVT recurrence(P＜0.05).When the FⅪ level was set into tertile and the risk ratio was calculated after adjustment,FⅪ＜10.3 U/L,and the average FⅪ level at this stage was 9.2 U/L,the risk ratio was 0.82(95％CI:0.673-0.984);Patients with FⅪ between 10.3 and 12.1 U/L,and the average FⅪ at this stage was 11.4 U/L,the risk ratio of 1.04(95％CI:0.813-1.432).The those with FⅪ＞12.1 U/L,and the average FⅪ at this stage was 13.8 U/L,hazard ratio of 1.38(95％CI:0.921-1.563).Kaplan-Meier curve analysis showed that the recurrence risk was 28.62％(95％CI:25.633-31.609),30.10％(95％CI:27.594-32.606)and 38.06％(95％CI:34.306-41.371),respectively for the low-,medium-,and high-level groups,with significant correlation among the three groups(x2=6.631,P=0.036).Conclusion Compared with healthy individuals,plasma FⅪ level is at a high level in the DVT patients.With the increment of FⅪ level,the risk of DVT recurrence increases.Two FⅪ levels,10.3 U/L and 12.1 U/L,can be used as reference points for the obvious increase of DVT recur-rence rate.

Objective To investigate the relationship between interleukin-1β (IL-1β) and miR-185-5p in the process of joint injury in acute gouty arthritis (AGA). Methods The serum miR-185-5p levels of 89 AGA patients and 91 healthy volunteers were detected by real-time quantitative PCR. The correlation between miR-185-5p expression level and VAS score or IL-1β expression level was evaluated by Pearson correlation coefficient method. Receiver operating characteristic (ROC) curve was used to evaluate the diagnostic value of miR-185-5p in AGA. THP-1 cells were induced by sodium urate (MSU) to construct an in vitro acute gouty inflammatory cell model. After the expression level of miR-185-5p in THP-1 cells was upregulated or downregulated by transfection of miR-185-5p mimics or inhibitors in vitro, inflammatory cytokines of THP-1 cells, such as IL-1β, IL-8 and tumor necrosis factor α (TNF-α), were detected by ELISA. The luciferase reporter gene assay was used to determine the interaction between miR-185-5p and the 3'-UTR of IL-1β. Results Compared with the healthy control group, the expression level of serum miR-185-5p in AGA patients was significantly reduced. The level of serum miR-185-5p was negatively correlated with VAS score and IL-1β expression level. The area under the curve (AUC) was 0.905, the sensitivity was 80.17% and the specificity was 83.52%. Down-regulation of miR-185-5p significantly promoted the expression of IL-1β, IL-8 and tumor necrosis factor (TNF-α), while overexpression of miR-185-5p showed the opposite results. Luciferase reporter gene assay showed that IL-1β was the target gene of miR-185-5p, and miR-185-5p negatively regulated the expression of IL-1β. Conclusion miR-185-5p alleviates the inflammatory response in AGA by inhibiting IL-1β.

Chemical cleaning and disinfection are crucial steps for eliminating infection in root canal treatment.However,irrigant selection or irrigation procedures are far from clear.The vapor lock effect in the apical region has yet to be solved,impeding irrigation efficacy and resulting in residual infections and compromised treatment outcomes.Additionally,ambiguous clinical indications for root canal medication and non-standardized dressing protocols must be clarified.Inappropriate intracanal medication may present side effects and jeopardize the therapeutic outcomes.Indeed,clinicians have been aware of these concerns for years.Based on the current evidence of studies,this article reviews the properties of various irrigants and intracanal medicaments and elucidates their effectiveness and interactions.The evolution of different kinetic irrigation methods,their effects,limitations,the paradigm shift,current indications,and effective operational procedures regarding intracanal medication are also discussed.This expert consensus aims to establish the clinical operation guidelines for root canal irrigation and a position statement on intracanal medication,thus facilitating a better understanding of infection control,standardizing clinical practice,and ultimately improving the success of endodontic therapy.

Objective:To comprehensively evaluate the clinical value of Elecsys serum abnormal prothrombin (PIVKA-Ⅱ) test reagent for auxiliary diagnosis of hepatocellular carcinoma (HCC) in the Chinese population.Methods:A multicenter case-control design was used in the study. Samples from patients with first-time confirmed, diagnosed, and untreated HCC, benign liver disease and interfering controls were collected continuously. Elecsys PIVKA-II and alpha-fetoprotein (AFP) were tested for analysis. Various clinical details of the subjects were collected and analyzed. The efficacy of PIVKA-II (21.29 ng/ml) and AFP (400 ng/ml) for HCC diagnosis was calculated at specific positive cut-off values. Statistical analysis was performed using the Kruskal-Wallis test or receiver operating characteristic curve.Results:A total of 448 subjects were eventually enrolled from five centers, including 185 HCC cases. PIVKA-II had a higher diagnostic sensitivity and accuracy than AFP (84.86% vs. 30.81% and 89.01% vs. 63.66%) when the benign liver disease group was used as the control group, while the specificity was slightly lower. A sensitive analysis showed that PIVKA-II had a sensitivity of >80% at this specific positive cut-off value in the subgroup of AFP-negative subjects, patients with different etiologies, and HCC patients with multiple Barcelona Clinic liver cancer stages (including early-stage HCC). At the same time, the PIVKA-II subject had a slightly higher area under the receiver operating characteristic curve than the AFP (0.920 0 vs. 0.880 9).Conclusion:The clinical efficacy of Elecsys PIVKA-Ⅱ is good and stable in the Chinese population. Additionally, it has the clinical potential to improve the current missed diagnosis status of AFP-negative HCC and HCC monitoring at an early stage, as well as the effectiveness of accuracy promotion for HCC auxiliary diagnosis in China.

Periarticular fracture of the shoulder is a common type of fractures in the elderly. Postoperative adverse events such as internal fixation failure, humeral head ischemic necrosis and upper limb dysfunction occur frequently, which seriously endangers the exercise and health of the elderly. Compared with the fracture with normal bone mass, the osteoporotic periarticular fracture of the shoulder is complicated with slow healing and poor rehabilitation, so the clinical management becomes more difficult. At present, there is no targeted guideline or consensus for this type of fracture in China. In such context, experts from Youth Osteoporosis Group of Chinese Orthopedic Association, Orthopedic Expert Committee of Geriatrics Branch of Chinese Association of Gerontology and Geriatrics, Osteoporosis Group of Youth Committee of Chinese Association of Orthopedic Surgeons and Osteoporosis Committee of Shanghai Association of Chinese Integrative Medicine developed the Chinese expert consensus on the diagnosis and treatment of osteoporotic periarticular fracture of the shoulder in the elderly ( version 2023). Nine recommendations were put forward from the aspects of diagnosis, treatment strategies and rehabilitation of osteoporotic periarticular fracture of the shoulder, hoping to promote the standardized, systematic and personalized diagnosis and treatment concept and improve functional outcomes and quality of life in elderly patients with osteoporotic periarticular fracture of the shoulder.

Objective:To explore the effects of frailty syndrome on activities of daily living and its associated risk for adverse outcomes among elderly residents in China.Methods:Using open data from "China Health and Retirement Longitudinal Survey", the 2011 baseline survey was conducted on general information, health risk factors, chronic disease, data obtained from various ability assessments and Fried frailty criteria assessments for community elderly aged 60 years and over.The follow-up data were used to analyze the adverse outcomes of frailty syndrome using a covariation-adjusted Logistic regression model.Results:Among the 5 630 people in the baseline population, 34.9%(1 963/5 630 cases)were non-frailty, 57.4%(3 236 cases)were pre-frailty, and 7.7%(431 cases)were frailty.The frailty group had higher rates of falls, hip fractures, hospitalizations, and death than the pre-frail and non-frail groups at the 3rd, 5th, and 8th years of follow-up.At follow up to 2015, the covariate-adjusted analysis of the study population showed that as compared with the non-frail group, the frail group had increased risks of falling( OR=1.738, 95% CI: 1.292-2.338, P<0.001), increased risks of hip fracture( OR=2.672, 95% CI: 1.365-5.233, P=0.004), increased risks of hospitalization( OR=1.670, 95% CI: 1.224-2.277, P=0.001), increased risk of death( OR=1.599, 95% CI: 1.256-2.035, P<0.001), increased risks of declined upper limb activity( OR=2.769, 95% CI: 2.101-3.650, P<0.001), of declined instrumental activity of daily living( OR=2.567, 95% CI: 1.941-3.395, P<0.001), and of declined basic activities of daily living( OR=2.790, 95% CI: 2.110-3.689, P<0.001). Conclusions:Frailty syndrome increases the risk of decreased ability to live, falls, hip fractures, hospitalization and death in older adults.Frailty screening is an effective tool for predicting the risk of adverse outcomes in elderly community populations.

Lower extremity deep vein thrombosis (DVT) is one of the main complications in patients with traumatic fractures, and for severe patients, the DVT can even affect arterial blood supply, resulting in insufficient limb blood supply. If the thrombus breaks off, pulmonary embolism may occur, with a high mortality. The treatment and rehabilitation strategies of thrombosis in patients with lower extremity fractures have its particularity. DVT in traumatic fractures patients has attracted extensive attention and been largely studied, and the measures for prevention and treatment of DVT are constantly developing. In recent years, a series of thrombosis prevention and treatment guidelines have been updated at home and abroad, but there are still many doubts about the prevention and treatment of DVT in patients with different traumatic fractures. Accordingly, on the basis of summarizing the latest evidence-based medical evidence at home and abroad and the clinical experience of the majority of experts, the authors summarize the clinical treatment and prevention protocols for DVT in patients with traumatic fractures, and make this consensus on the examination and assessment, treatment, prevention and preventive measures for DVT in patients with different fractures so as to provide a practicable approach suitable for China ′s national conditions and improve the prognosis and the life quality of patients.

Sarcopenia is a geriatric syndrome characterized by loss of skeletal muscle mass and strength and functional decline due to aging.In recent years, with the increase of the aging population, the incidence of the disease continues to rise.It is associated with a variety of adverse events such as falls, frailty, increased mortality, and other adverse events.Therefore, as research continues to lead to improved understanding on risk factors, pathophysiological mechanisms and intervention of sarcopenia, rehabilitation has become an important means in clinical treatment.This paper systematically reviews the progress in rehabilitation therapy for patients with sarcopenia, in order to summarize evidence for clinical intervention of sarcopenia.

Objective:To investigate the prevalence of sarcopenia among community-dwelling Chinese elderly and to explore the related factors.Methods:Data were obtained from the China Health and Retirement Longitudinal Survey(CHARLS)in 2015, an open national database.According to the criteria of the Asian Working Group(AWGS)on Sarcopenia in 2014, a cross-sectional survey was conducted on 7 584 Chinese residents aged 60 years and over who had undergone the standard sarcopenia test.General socio-demographic characteristics and living habits were compared between different gender groups.The prevalence of sarcopenia was analyzed with stratification.Multivariate Logistic regression analysis was used to analyze risk factors for sarcopenia.Results:The overall prevalence of sarcopenia was 6.4%(95% CI: 5.9-7.0)among the Chinese population aged 60 years or older.In the stratified analysis, the prevalence of sarcopenia was higher in males(9.9%, 95% CI: 9.0-10.9)than in females(3.0%, 95% CI: 2.4-3.5), in rural areas(7.2%, 95% CI: 6.5-7.9)than in urban areas(4.3%, 95% CI: 3.4-5.2), and in smokers(8.8%, 95% CI: 7.6-10.0)than in non-smokers(4.2%, 95% CI: 3.6-4.8). Multivariate Logistic regression showed that male gender( OR=5.368, 95% CI: 4.126-6.985)and old age( OR=1.191, 95% CI: 1.172-1.210)were risk factors for sarcopenia.In addition, the occurrence of sarcopenia was significantly associated with physical pain( OR=2.181, 95% CI: 1.695-2.673), alcohol consumption( OR=1.426, 95% CI: 1.057-1.923), low education level( OR=2.875, 95% CI: 1.577-5.241), increased waist circumference( OR=0.982, 95% CI: 0.973-0.990), decreased peak expiratory flow( OR=0.995, 95% CI: 0.994-0.997)and increased cystatin C levels( OR=2.088, 95% CI: 1.247-3.495)( P<0.05). Conclusions:The prevalence of sarcopenia is high among community-dwelling elderly in China, and the occurrence of sarcopenia is closely related to age, gender, education level, Waist circumference and alcohol consumption.
