Osteoporotic proximal humeral fracture (OPHF) is one of the common osteoporotic fractures in the aged, with an incidence only lower than vertebral compression fracture, hip fracture, and distal radius fracture. OPHF, secondary to osteoporosis and characterized by poor bone quality, comminuted fracture pattern, slow healing, and severely impaired shoulder joint function, poses a big challenge to the current clinical diagnosis and treatment. In the field of diagnosis, treatment, and rehabilitation of OPHF, traditional Chinese and Western medicine have accumulated rich experience and evidence from evidence-based medicine and achieved favorable outcomes. However, there is still a lack of guidance from a relevant consensus as to how to integrate the advantages of the two medical systems and achieve the integrated diagnosis and treatment. To promote the diagnosis and treatment of OPHF with integrated traditional Chinese and Western medicine, relevant experts from Orthopedic Expert Committee of Geriatric Branch of Chinese Association of Gerontology and Geriatrics, Youth Osteoporosis Group of Orthopedic Branch of Chinese Medical Association, Osteoporosis Group of Orthopedic Surgeon Branch of Chinese Medical Doctor Association, and Osteoporosis Committee of Shanghai Association of Integrated Traditional Chinese and Western Medicine have been organized to formulate Expert consensus on the diagnosis and treatment of osteoporotic proximal humeral fracture with integrated traditional Chinese and Western medicine ( version 2024) by searching related literatures and based on the evidences from evidence-based medicine. This consensus consists of 13 recommendations about the diagnosis, treatment and rehabilitation of OPHF with integrated traditional Chinese medicine and Western medicine, aimed at standardizing, systematizing, and personalizing the diagnosis and treatment of OPHF with integrated traditional Chinse and Western medicine to improve the patients ′ function.

Objective:To explore the clinical value of a trinity strategy for the treatment of multiple orthopedic trauma.Methods:A retrospective case series study was conducted to analyze the clinical data of 1 267 patients with multiple orthopedic trauma admitted to Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine and the First Affiliated Hospital of Navy Medical University from June 2013 to May 2023, including 862 males and 405 females, aged 18-93 years [(55.2±19.8)years]. Associated injuries included hemorrhagic shock in 632 patients, traumatic wet lung in 274, cranial injuries in 135, abdominal and pelvic bleeding in 116, pneumothorax in 89, urinary injury in 13, and vesical rupture in 8. All the patients were treated with the trinity strategy and the treatment process was divided into the phases of first aid, remodeling, and rehabilitation. The first aid phase focused on stabilizing symptoms and saving lives; the remodeling phase centered on restoring the anatomical structure and alignment; the rehabilitation phase aimed for functional recovery through the integration of both Western and traditional Chinese medicine. The all-cause mortality within 30 days after surgery and fracture healing time were calculated; the excellent and good rates of Constant-Murley shoulder score, Mayo elbow score, Gartland-Werley wrist score, Harris hip score, Hospital for Special Surgery (HSS) knee score and the American Orthopedic Foot & Ankle Society (AOFAS) ankle-hindfoot score at the last follow-up and the overall excellent and good rate of all joint function scores were measured. The short form health survey (SF-36) scores were collected preoperatively and at 6 months postoperatively, including 8 aspects such as physical functioning, physical role, bodily pain, general health, vitality, social functioning, emotional role, and mental health. The incidence of postoperative complications was recorded.Results:All the patients were followed up for 6-18 months [(10.2±4.2)months]. The mortality rate during the acute phase (within 30 days after surgery) was 2.37% with 12 deaths due to hemorrhagic shock, 10 due to traumatic brain injury, 6 due to multiple organ dysfunction syndrome (MODS), and 2 due to pulmonary infection. The average fracture healing time averaged 3.8-18 months [(11.5±4.2)months], with 89.49% of the patients having bone union within 12 months after surgery, 8.93% having bone union within 18 months after surgery, and 1.58% undergoing reoperation. For the patients with internal fixation failure and nonunion, the average healing time was extended to (10.2±2.2)months and (13.7±3.3)months respectively. At the last follow-up, the excellent and good rates of Constant-Murley shoulder score, Mayo elbow score, Gartland-Werley wrist score, Harris hip score, HSS knee score, and AOFAS ankle-hindfoot score were 83.93%, 90.24%, 94.12%, 85.57%, 88.46%, and 92.31% respectively, with an overall excellent and good rate of 89.11%. At 6 months after surgery, the SF-36 scores of all the patients in the eight dimensions,including the physical functioning, physical role, bodily pain, general health, vitality, social functioning, emotional role, and mental health were (74.4±8.6)points, (44.7±14.4)points, (77.4±10.9)points, (68.4±18.2)points, (72.5±16.0)points, (76.8±8.7)points, (49.9±17.6)points, and (72.8±17.9)points, significantly improved compared with those before operation [(63.4±12.7)points, (30.9±17.4)points, (56.4±18.0)points, (55.4±24.7)points, (53.5±21.0)points, (55.8±24.3)points, (36.9±24.0)points, (58.8±21.6)points] ( P<0.01). Complications of different degrees occurred in 214 patients (16.89%), including lung infections in 118 patients (9.31%), lower extremity deep vein thrombosis in 50(3.95%), pressure injuries in 26(2.05%), internal fixation failure in 12(0.95%), and nonunion in 8(0.63%). Conclusions:The trinity strategy provides whole-process management, personalized treatment, and overall rehabilitation for multiple orthopedic trauma. It can decrease mortality, shorten fracture healing time, improve joint function and quality of life, and reduce the incidence of complications.

Anxiety is a major mood disorder, and the high morbidity, co-morbidity and disability of anxiety disorders seriously affect people's quality of life, so the importance and urgency of research on anxiety cannot be overstated. Animal models are the main carriers for studying the mechanism of disease occurrence and development, drug efficacy evaluation and drug development.Unconditioned anxiety model is a common anxiety model.Elevated plus maze test, open field test and light-dark box test are widely accepted paradigms for the detection of unconditioned anxiety.This kind of behavioral paradigm based on environmental exposure takes advantage of the conflict between curiosity and fear of the unfamiliar environment to simulate and detect the anxiety of animals.However, the validity of these behavioral paradigms for evaluating anxiety in animals is questionable.In this paper, we discuss the concept of anxiety, the definition of anxiety behavior in the behavioral test of unconditioned anxiety, and the factors to be considered in the test of unconditioned anxiety behavior.On this basis, new solutions were proposed to the contradictions and blind spots in order to improve the test paradigm of anxiety behavior and provide a more reliable animal model for the evaluation of anxiety.This paper presents a new approach to address the contradictions and blind spots of this paradigm.

Objective:To investigate the effects of regional citrate anticoagulation in continuous veno-venous hemofiltration (CVVH) of severe burn patients.Methods:A retrospective non-randomized controlled study was conducted. From January 2017 to August 2020, sixty-eight severe burn patients who met the inclusion criteria were treated with CVVH in Affiliated Hospital of Nankai University. According to the different methods of blood anticoagulation in CVVH treatment, patients were divided into citrate group ( n=40) and heparin group ( n=28). In the citrate group, 32 males and 8 females were (40±18) years old with total burn area of (62±14)% total body surface area (TBSA); in the heparin group, 22 males and 6 females were (38±16) years old with total burn area of (57±20)%TBSA. Creatinine level, C-reactive protein (CRP) value, and urea nitrogen level in serum of patients were recorded at 0 (immediately), 48, and 96 h after CVVH treatment in 2 groups, urea clearance index was calculated based on urea nitrogen level at 0, 48, and 96 h after CVVH treatment in 2 groups, platelet count (PLT), prothrombin time (PT), and activated partial thromboplastin time (APTT) in total coagulation of patients were recorded. The frequency of forced hemofiltration termination caused by adverse reactions such as severe hypocalcemia, aggravated wound bleeding, and new bleeding on non-wound surface of patients was recorded within 96 h of CVVH treatment. The duration of daily CVVH use from the beginning to the end was recorded. Data were statistically analyzed with chi-square test, analysis of variance for repeated measurement, independent samples t test, and Bonferroni correction. Results:There were no significant differences in urea nitrogen level, creatinine level, and CRP value in serum of patients between 2 groups at 0 h after treatment ( P>0.05). At 48 and 96 h after treatment, urea nitrogen level, creatinine level, and CRP value in serum of patients in citrate group were significantly lower than those in heparin group ( t=3.366, -2.315, 2.942, -2.657, 2.011, -2.441, P<0.05), and urea clearance index of patients in citrate group was significantly higher than that in heparin group ( t=1.017, 2.233, P<0.05). There were no statistically significant differences in PLT, PT, and APTT of patients between 2 groups at 0 h after treatment ( P>0.05). At 48 and 96 h, PLT of patients in citrate group was significantly higher than that in heparin group ( t=-3.417, -4.143, P<0.05 or P<0.01), PT of patients in citrate group was significantly shorter than that in heparin group ( t=2.760, -3.655, P<0.01), APTT of patients in citrate group was significantly shorter than that in heparin group ( t=3.719, 5.146, P<0.05 or P<0.01). Within 96 h of treatment, there was 1 case of hypocalcemia and 1 case of aggravated wound bleeding resulting in forced hemofiltration termination in citrate group, but there was no new bleeding on non-wound surface; in heparin group, there was no hypocalcemia, but 7 cases of aggravated wound bleeding and 2 cases of new bleeding on non-wound surface (both at the tracheotomy site) resulting in forced hemofiltration termination. The use time of blood purification filter of patients in citrate group was (11.7±4.8) h, obviously longer than (6.6±2.5) h in heparin group ( t=3.310, P<0.01). Conclusions:The use of regional citrate anticoagulation in CVVH treatment of severe burn patients has the advantages including little effect on coagulation function and high safety, can effectively prolong the use time of filter and improve the therapeutic effect, but this conclusion still needs to be further verified in clinical application.

Objective:To summarize the genetic diagnosis of two fetuses with clinically suspected Bardet-Biedl syndrome (BBS) and to provide information for genetic counseling and prenatal diagnosis of BBS.Methods:Case one had prenatal care on October 2018 in Shenzhen Maternity and Child Healthcare Hospital and was clinically suspected of fetal BBS as bilateral renal parenchyma echo enhancement as well as polydactyly (six toes on each foot) were shown on ultrasonic examination at 18 +1 gestational weeks. Case two was another suspected fetal BBS for enlarged kidneys with echo enhancement as well as polydactyly (six fingers and toes on each hand and foot) on ultrasonic examination at 26 +4 gestational weeks on August 2016 and the parent requested for termination. Parents of both cases requested for genetic analysis. Amniotic fluid sample was obtained in case one at 19 +6 weeks through amniocentesis, and umbilical cord specimen of case two and peripheral blood samples of the parents were collected. Genetic analysis of the fetuses and their parents was performed using exon capture and next-generation sequencing and the results were validated using Sanger sequencing. Results:Case one carried paternally inherited c.718G>A (p.Gly240Ser) (possible pathogenic) mutation and maternally inherited c.497C>A(p.Ala166Asp) (possible pathogenic) mutation in BBS7 gene. While one paternally inherited mutation c.1002delT(p.N335Ifs*47) (pathogenic) and one maternally inherited heterozygous mutation c.728G>A (p.Cys243Tyr) (possible pathogenic) were identified in BBS7 gene of case two. The three unreported missense mutations were predicted to be harmful by bioinformatics software and the mutation sites were conservative after comparing with multiple species-based protein sequences. Conclusions:Enlarged kidneys with echo enhancement and polydactyly may indicated a BBS fetus caused by BBS7 gene mutation. Whole exome sequencing could provide relevant information for prenatal diagnosis and genetic counseling in these cases.

Objective: To explore the influence of directed restrictive fluid management strategy (RFMS) on patients with serious burns complicated by severe inhalation injury. Methods: Sixteen patients with serious burns complicated by severe inhalation injury hospitalized in our department from December 2014 to December 2017, meeting the inclusion criteria and treated with RFMS, were enrolled in directed treatment group. Thirty-four patients with serious burns complicated by severe inhalation injury hospitalized in our department from December 2012 to December 2017, meeting the inclusion criteria and without RFMS, were enrolled in routine treatment group. Medical records of patients in 2 groups were retrospectively analyzed. Within post injury day 2, mean arterial pressure (MAP), central venous pressure (CVP), extravascular lung water index (ELWI), global end-diastolic volume index, and pulmonary vascular permeability index of patients in directed treatment group were monitored by pulse contour cardiac output monitoring technology, while MAP and CVP of patients in routine treatment group were monitored by routine method. On post injury day 3 to 7, patients in 2 groups were treated with routine fluid supplement therapy of our Department to maintain hemodynamic stability, and patients in directed treatment group were treated according to RFMS directed with goal of ELWI≤7 mL·kg^-1·m^-2. On post injury day 3 to 7, total fluid intake, total fluid output, and total fluid difference between fluid intake and output within 24 h, value of blood lactic acid, and oxygenation index of patients in 2 groups were recorded. Occurrence of acute respiratory distress syndrome (ARDS) on post injury day 3 to 7 and 8 to 28, mechanical ventilation time within post injury day 28, and occurrence of death of patients in 2 groups were counted. Data were processed with chi-square test, t test, and analysis of variance for repeated measurement. Results: The total fluid intakes within 24 h of patients in directed treatment group were close to those in routine treatment group on post injury day 3, 4, 5, 6, 7 (t=-0.835, -1.618, -2.463, -1.244, -2.552, P>0.05). The total fluid outputs and total fluid differences between fluid intake and output within 24 h of patients in 2 groups on post injury day 3 were close (t=0.931, -2.274, P>0.05). The total fluid outputs within 24 h of patients in directed treatment group were significantly higher than those in routine treatment group on post injury day 4, 5, 6, 7 (t=2.645, 2.352, 1.847, 1.152, P<0.05). The total fluid differences between fluid intake and output within 24 h of patients in directed treatment group were (2 928±768), (2 028±1 001), (2 186±815), and (2 071±963) mL, significantly lower than (4 455±960), (3 434±819), (3 233±1 022), and (3 453±829) mL in routine treatment group (t=-4.331, -3.882, -3.211, -4.024, P<0.05). The values of blood lactic acid of patients in directed treatment group and routine treatment group on post injury day 3, 4, 5, 6, 7 were close (t=0.847, 1.221, 0.994, 1.873, 1.948, P>0.05). The oxygenation indexes of patients in directed treatment group on post injury day 3 and 4 were (298±78) and (324±85) mmHg (1 mmHg=0.133 kPa ), which were close to (270±110) and (291±90) mmHg in routine treatment group (t=-1.574, 2.011, P>0.05). The oxygenation indexes of patients in directed treatment group on post injury day 5, 6, 7 were (372±88), (369±65), and (377±39) mmHg, significantly higher than (302±103), (313±89), and (336±78) mmHg in routine treatment group (t=3.657, 3.223, 2.441, P<0.05). On post injury day 3, 4, 5, 6, 7, patients with ARDS in directed treatment group were less than those in routine treatment group, but with no significantly statistical difference between the 2 groups (χ²=0.105, P>0.05). On post injury day 8 to 28, patients with ARDS in directed treatment group were significantly less than those in routine treatment group (χ²=0.827, P<0.05). The mechanical ventilation time within post injury day 28 of patients in directed treatment group was apparently shorter than that in routine treatment group (t=-2.895, P<0.05). Death of patients in directed treatment group within post injury day 28 was less than that in routine treatment group, but with no significantly statistical difference between the 2 groups (χ²=0.002, P>0.05). Conclusions Under the circumstance of hemodynamics stability, RFMS directed with goal of ELWI≤7 mL·kg^-1·m^-2 on post injury day 3 to 7 is an useful strategy, which can reduce occurrence rate of ADRS and shorten mechanical ventilation time of patients with serious burns complicated by severe inhalation injury at late stage of burns.

OBJECTIVE To provide prenatal diagnosis for families affected with tuberous sclerosis complex and explore the correlation between phenotype and genotype. METHODS For probands from 10 families, all exons and splicing regions of the TSC1 and TSC2 genes were analyzed with high throughput DNA sequencing. Suspected mutations were verified by Sanger sequencing. RESULTS All probands were found to have mutations, which included 1 case with TSC1 mutation and 9 cases with TSC2 mutations (missense mutations in 6, nonsense mutations in 2, and frameshifting mutation in 1 case). Prenatal diagnosis was provided for 9 cases, and 1 fetus was found to carry a mutation. Genetic analysis has identified a novel pathogenic mutation (TSC2 c.2415-2416 ins GT). CONCLUSION Identification of pathological mutations for tuberous sclerosis complex can facilitate genetic counseling and prenatal diagnosis for the affected families.

Objective To investiget the value of chromosome microarray analysis (CMA) in prenatal diagnosis of Jacobsen syndrome.Methods Among all gravidas who received karyotype analysis and CMA because of fetal congenital cardiac abnormalities in Shenzhen Maternity & Child Healthcare Hospital Affiliated to Southern Medical University from 2014 to 2016,four were diagnosed with fetal Jacobsen syndrome and enrolled in this study.Three amniotic fluid and one fetal tissue samples were collected.Peripheral blood specimens were collected from parents of these fetuses.Amniotic fluid samples and peripheral blood specimens were analyzed by karyotype analysis.CMA was performed to analyze amniotic fluid and fetal tissue samples.Multiplex ligation-dependent probe amplification was used to verify abnormal results revealed by CMA.Results (1) Prenatal ultrasound results:Fetus 1 was complicated with monocardian and transposition of the great arteries,fetus 2 with single umbilical artery and double superior vena cava,fetus 3 with severe constricted aorta and ventricular septal defect and fetus 4 with hypoplastic left heart syndrome and presented with a nuchal translucency of 0.27 cm.(2) Karyotyping results of the three amniotic fluid samples were 46,XY,del(11)(q23.3),46,XX,del(11)(q23.3) and 46,XX,del(11)(q23),respectively.(3) CMA results of the four fetuses were arr[GRCh37]11q24.1q25(121 872 273-134 934 196)× 1(13.062 Mb),arr[GRCh37]11q24.1q25(121 325 694-134 937 416)× 1 (13.611 Mb),arr[GRCh37]11q23.3q25(118 977 029-134 937 416)× 1 (15.960 Mb) and arr[GRCh37]11q24.1q24.3(123 144 040-130 308 335)× 1(7.164 Mb),respectively.All chromosomal aberrations in these fetuses were de novo as no abnormalities were found in their parents through karyotyping.All abnormal CMA results were confirmed by multiplex ligation-dependent probe amplification.Conclusions Jacobsen syndrome should be considered when fetuses are diagnosed with congenital cardiac abnormalities by ultrasound.CMA can be used to accurately diagnose Jacobsen syndrome and determine the region and size of chromosome deletion.
