[Objective]To explore the diagnostic value of conventional ultrasound combined with shear wave elastography (SWE) for sarcopenia in patients with chronic kidney disease (CKD).[Methods]The study included 94 CKD patients (34 with sarcopenia and 60 without). All patient underwent the Simplified Assessment Rating Questionnaire (SARC-CalF),Mini Nutritional Assessment (MNA),Short Physical Performance Battery (SPPB),grip strength test,bioelectrical impedance analysis (BIA),conventional muscle ultrasound and SWE of the thighs. We then compared the differences in indicators between the sarcopenia group and non-sarcopenia group,used Spearman correlation analysis to assess the relationship between the two examinations (conventional ultrasound and SWE) and other clinical indicators,identified the diagnostic markers for sarcopenia,created receiver operating characteristic (ROC) curves,calculated the area under the curve (AUC) and determined the diagnostic performance of conventional ultrasound,SWE and their combination. Binary logistic regression was used to analyze the influencing factors of sarcopenia in CKD patients and a combined diagnosis model was established.[Results]The sarcopenia group showed lower upper arm circumference,calf circumference,6-meter walking speed and handgrip strength than non-sarcopenia group,and the differences were statistically significant (P<0.05). The sarcopenia group exhibited lower SARC-CalF and SPBB scores,as well as more compromised nutritional status. Statistically significant differences were observed in the ultrasound parameters between the two groups,including thickness of the subcutaneous fat and rectus femoris,combined thickness of the rectus femoris and vastus intermedius,rectus femoris cross-sectional area,elastic modulus of the rectus femoris and vastus medialis (all P<0.05). The muscle mass index had a moderate positive correlation with muscle thickness and cross-sectional area of the rectus femoris (0.3

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.

Objective A scoping review of research on mobile glucose management in pregnant women with gestational diabetes mellitus was conducted to provide references for clinical providers to conduct mobile glucose management and related research.Methods Based on Arksey and O'Malley's scoping review reporting framework,JBI Library,Cochrane Library,PubMed,Web of Science,Embase,CINAHL Complete,CBM,China National Knowledge In-frastructure(CNKI),and Wanfang Database were retrieved.The search time frame was from the establishment of the databases to February 14,2023.The included literature was screened,summarized and analyzed.Results A total of 65 publications from 11 countries were included,among which 38 were randomized controlled trials,27 were experimental studies.The vehicles relied on for mobile glucose management in gestational diabetes mainly included APPs,remote monitoring systems,professional websites,and social platforms,which could provide health education,glucose management monitoring and recording,social support,and glucose management follow-up and reminders to pregnant women.Most of the studies focus on the glucose index and drug use,pregnancy outcome,self-management,quality of life,user experience and resource cost of pregnant women.Conclusion Mobile glucose management carriers are geographically specific and have a positive effect on glucose control in gestational diabetes.Future studies need to further develop localized mobile glucose management intervention protocols and conduct more high-quality randomized controlled studies to verify their effectiveness.

Objective To determine the role of programmed cell death-ligand l(PD-L1)and cluster of differentiation 8(CD8)in judging the prognosis of human epidermal growth factor receptor 2(HER2)positive breast cancer patients,through evaluating the expression of PD-L1 and CD8 in the tumor microenvironment,and their correlation with clinicopathological data.Methods A total of 65 HER2 positive breast cancer patients were collected admitted to Tengzhou Central People's Hospital in Shandong Province from October 2016 to October 2018,all of whom were women.Theparaffin slices of cancer tissue were labeled with PD-L1 and CD8 using immunohistochemical methods.Collect clinicopathological data of patients,including 7 prognostic parameters,such as age,histological grade,P53,KI-67,estrogen receptor,progesterone receptor and tumor node metastasis classification(TNM)staging.Statistical analysis was conducted to determine whether the expression of PD-L1 and CD8 were correlated with the above clinicopathological data.Results PD-L1 positive rate was 21.5％,the positive expression of PD-L1 was correlated with histological grading and TNM staging,and the difference in results was statistically significant(x2=6.250,P=0.044;x2=13.730,P=0.001);CD8 positive rate was 32.3％,the expression of CD8 cells was correlated with histological grading and TNM staging,and the difference in results was statistically significant(x2=8.023,P=0.018;x2=6.117,P=0.047).Conclusion PD-L1 and CD8 expression are correlated with breast cancer histological grade and TNM stage.PD-L1 and CD8 expression may be important prognostic markers for HER2 positive breast cancer patients.

Objective:To design and construct a bone nonunion organoid on chip and explore the mechanism of aseptic bone nonunion.Methods:First a semi-open microfluidic chip was designed, on which human bone marrow mesenchymal stromal cells (BMSC), human fetal lung fibroblast 1, (HFL1) and human umbilical vein endothelial cells (HUVEC) were co-cultured, and a three-dimensional organ on chip system was established. Different proportions of HFL1 and HUVEC were co-cultured with BMSC, which were divided into the control group (HFL1∶HUVEC=1∶1), the fibrosis group (HFL1∶HUVEC=3∶1) and the vascularization group (HFL1∶HUVEC=1∶3). The osteogenic differentiation of BMSC was observed by alkaline phosphatase (ALP) and Alizarin red staining. The transcription level of osteogenic marker genes SP7, RUNX2, ALPL, and BGLAP, and vascularization related genes KDR and VWF were analyzed by qPCR. The expression levels of RUNX2 and ALP were determined by Western Blot. Results:In the co-culture system of BMSCs, HFL1, and HUVECs, BMSCs exhibited normal growth and apparent biomineralization behavior. Endothelial cells were capable of forming structured vascular networks, confirming the successful establishment of the system. Compared to the baseline group, the fibrotic group showed no significant decrease in BMSC osteogenic differentiation. The relative expression levels of the mineralization marker genes ALPL and BGLAP were 0.55±0.19 ( P<0.001) and 0.42±0.27 ( P<0.001), respectively. Vascularization genes KDR and VWF were downregulated, with relative expression levels of 0.49±0.17 ( P<0.001) and 0.49±0.21 ( P<0.001). In contrast, in the vascularized group, BMSC osteogenic differentiation genes SP7, RUNX2, ALPL, and BGLAP were upregulated, with relative expression levels of 2.91±0.52 ( P<0.001), 3.83±1.87 ( P<0.001), 3.22±1.29 ( P<0.001), and 5.21±1.46 ( P<0.001), respectively. Vascularization genes KDR and VWF were also upregulated, with relative expressions of 8.24±2.84 ( P<0.001) and 5.32±1.67 ( P<0.001). Western blot results indicated increased expression of RUNX2 and ALP in the vascularized group and decreased expression in the fibrotic group. Conclusion:The bone nonunion organoid on chip could partially simulate the local microenvironment of bone nonunion. Fibrosis may lead to a significant decrease in bone formation ability and vascularization level, which might be an important reason for the occurrence of aseptic bone nonunion.

Objective:To investigate the clinical characteristics of family clustering pediatric and adult cases with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant infection in Shanghai City.Methods:A field investigation among the pediatric cases with Omicron variant infection and their household contacts from April 4 to April 30, 2022 in Children′s Hospital of Fudan University was conducted. The informations on case finding, clinical manifestations and SARS-CoV-2 vaccination status were collected. The epidemiological and clinical characteristics were compared between pediatric cases and adult cases. The independent sample t test or chi-square test was used for statistical analysis, and the relative risk ( RR) and 95% confidence interval (95% CI) were used to evaluate the protective effect of vaccination on the infection of Omicron variant. Results:There were 1 274 family members in 297 families including 370 children and 904 adults of whom 1 110(87.13%) were infected with Omicron variant, with 989(89.10%) symptomatic and 121(10.90%) asymptomatic. There were 355 children infected with Omicron variant, of whom 337(94.93%) were symptomatic, and the main manifestations were fever (96.74%(326/337)) and cough (40.36%(136/337)). Only one pediatric case with Rett syndrome developed critically severe pneumonia. A total of 194 pediatric cases had imaging examination, 64(32.99%) showed pulmonary inflammatory lesions. There were 755 adult cases infected with Omicron variant, of whom 652(86.26%) reported symptoms, and the main manifestations were fever (73.16%(477/652)) and cough (49.85%(325/652)). Among symptomatic cases, fever was more common in pediatric cases than in adult cases, while cough was more common in adult cases than in pediatric cases, and the differences were both statistically significant ( χ2=80.87 and 8.04, respectively, both P<0.01). The fever spike was higher in pediatric cases than in adult cases ((39.3±0.7) ℃ vs (38.6±0.6) ℃), and the difference was statistically significant ( t=9.85, P<0.001). The interval from the onset of symptoms to cycle threshold (Ct) value of the nucleic acid of Omicron variant≥35 was longer in pediatric cases than in adult cases ((13.0±3.1) d vs (10.9±3.6) d), and the difference had statistically significance ( t=2.97, P=0.004). Among 160 children aged 3 to 18 years, 54 (33.75%) received two-dose vaccination. Among the 904 adults, 388 (42.92%) received two-dose vaccination and 293 (32.41%) received a booster dose. In the adult cases, the risk of symptomatic infection was reduced by only 8% ( RR=0.92, 95% CI 0.86 to 0.98, P=0.014) following two-dose vaccination, and the risks of fever and cough following booster vaccination were reduced by 42%( RR=0.58, 95% CI 0.49 to 0.67, P=0.001) and 50% ( RR=0.50, 95% CI 0.34 to 0.78, P=0.001), respectively. Conclusions:Secondary attack rate and symptomatic rate of household infection are high in the context of the Omicron variant outbreak in Shanghai. Symptomatic infection is common in children and adults in household setting. Fever is the most common symptom and fever duration is short. Booster vaccination may provide certain protection against common symptoms caused by Omicron variant infection.

Objective:To evaluate the efficacy and safety of non-osteotomy total hip arthroplasty (THA) in the treatment of Crowe IV developmental dysplasia of the hip (DDH).Methods:From Jan 2013 to Sep 2021, 46 patients (46 hips) in our department who underwent total hip arthroplasty without osteotomy for unilateral Crowe IV DDH were retrospectively analyzed, including 6 males and 40 females, with an average age of 41.2±7.2 years (25-61 years). The reduction of the femoral head was achieved successfully through moderate upward-posterior displacement of the movement center, gradual osteotomy of the calcar femorale, proper sinking of the femoral prosthesis and sufficient soft tissue release. The evaluation indexes included the basic condition of the operation (operation time, blood loss, blood transfusion, volume), clinical evaluation (Harris score of hip joint function, patient satisfaction, Trendelenburg sign), imaging evaluation (measurement of limb length and pelvic inclination) and incidence of complications.Results:The mean follow-up time was 72.2±8.8 months (8-101 months). The operation time was 97.2±12 min (84-112 min). The average intraoperative bleeding volume was 550±60 ml (350-850 ml). No patient had periprosthetic infection or fracture, no periprosthetic osteolysis or prosthesis loosening, and no patient needed revision surgery at the last follow-up of all cases. The average HHS score of patients increased from 42.5±12.3 points before surgery to 89.2±10.8 points at the last follow-up, and the difference was statistically significant ( t=19.35, P<0.001). Patient self-rated satisfaction: none was very dissatisfied, 1 patient were less satisfied (2%, 1/46), 4 patients were average (9%, 4/46), 19 patients were relatively satisfied (41%, 19/46), and 22 patients were very satisfied (48%, 22/46). The Trendelenburg sign of 46 cases was positive before operation, and all were negative at the last follow-up. The patients' true leg length discrepancy (LLD) measurement was -2.5±0.6 mm before surgery and 11.5±3.2 mm at the last follow-up ( t=29.17, P<0.05). Patients' perceived LLD was 28.2±5.1 mm before surgery and 3.4±1.4 mm at the last follow-up ( t=32.18, P<0.05). The length of the residual calcar femorale was 3.2±0.4 mm after THA. The limb extended distance of affected limb was 45.2±4.6 mm. The preoperative iliolumbar angle was -6.5°±2.3°, which returned to -0.5°±1.3° at the last follow-up ( F=651.97, P<0.05). Conclusion:For patients with unilateral type IV DDH, non-osteotomy THA is a safe and effective surgical method with simple operation and few complications. It can quickly correct pelvic tilt and lumbar compensatory scoliosis postoperatively.

Objective:To understand the clinical characteristics of children with SARS-CoV-2 Omicron infection imported from Hong Kong Special Administrative Region.Methods:This retrospective study was conducted to collect the data including clinical manifestations, outcomes and vaccination of 107 children with SARS-CoV-2 Omicron infection imported from Hong Kong Special Administrative Region to be admitted to the designated referral hospital in Shanghai from February to March 2022. According to the occurrence of clinical symptoms, the cases were divided into asymptomatic group and symptomatic group. According to the age of diagnosis, the cases were divided into <3 years group, 3-<6 years group and 6-<18 years group, and the clinical manifestations in different age group were analyzed with t-test and Mann-Whitney rank-sum test. Besides, to analyze the effectiveness of vaccination against SARS-CoV-2 Omicron infection in different age group, the cases aged 3-<18 years were also subdivided into unvaccinated group, 1-dose group and 2-dose group, and the relative risk ( RR) was used to demonstrate the effectiveness. Results:Among the 107 cases, 66 were male and 41 were female, with infection age of 10 (5, 14) years. There were 29 cases in the asymptomatic group, and 78 cases in the symptomatic group, and no significant difference in the age of infection was observed between the 2 groups (11 (6, 14) vs. 10 (5, 14) years, Z=0.49, P>0.05). And there were no severe cases in symptomatic group. The length of hospitalization was (18±6) days, and was longer in symptomatic group than that in asymptomatic group ((19±6) vs. (16±7) d, t=0.17, P=0.030). Eight-two cases (76.6%) had a history of epidemiological exposure and, among whom, 81 cases (75.7%) were associated with household transmission. Among symptomatic group, 57 cases (73.1%) had fever and 20 cases (25.6%) had cough. Of the 74 cases undergoing chest CT examination, 17 cases (23.0%) showed mild abnormalities. Of the 83 cases who received the lab tests, 23 cases (27.7%) had white blood cell counts<4×10 9/L, 3 cases (3.6%) had C-reaction protein >8.0 mg/L, and 6 cases (7.2%) had slightly elevated aspartate transaminase and alanine aminotransferase. Among the 92 children aged 3-<18 years, 31 cases were unvaccinated, 34 cases received 1 dose, and 27 cases received 2 doses. The interval between the last vaccination and infection was 2.2 (0.6, 6.0) months; the interval between the last vaccination and infection in the 2-dose group was longer than that in 1-dose group (6.0 (4.5, 7.3) vs. 0.7 (0.3,2.0) months, Z=3.59, P<0.001).The risk of symptomatic infection was reduced by 45% (RR=0.55, 95% CI 0.35-0.87) with two-dose vaccination compared to non-vaccination in cases aged 3-<18 years. All these cases recovered completely. Conclusions:Children infected with SARS-CoV-2 Omicron are usually mild or asymptomatic. Household transmission is the main pattern of infection with SARS-CoV-2 Omicron in children. Two-dose SARS-CoV-2 vaccination in children aged 3-<18 years can provide partial protection against disease caused by SARS-CoV-2 Omicron.
