Objective: To investigate the status and influencing factors of influenza vaccination among the elderly, so as to provide insights into improving the strategies for influenza vaccination among the elderly. Methods: Elderly people aged 60 years and above were recruited from one community each in five sub-districts of Shihezi City, Xinjiang Uygur Autonomous Region using a random sampling method. Demographic information, knowledge about influenza and influenza vaccines, vaccine literacy and influenza vaccination status in the past year were collected through questionnaire surveys. Factors affecting influenza vaccination among the elderly were analyzed using a multivariable logistic regression model. Results: Totally 1 121 valid questionnaires were recovered, with an effective recovery rate of 95.08%. There were 417 males (37.20%) and 704 females (62.80%). The majority were aged 60-<81 years, accounting for 80.37% (901 individuals). The awareness of knowledge about influenza and influenza vaccines was 78.86%. Low vaccine literacy was observed in 786 individuals, representing 70.12%. The influenza vaccination rate was 20.96%. Multivariable logistic regression analysis showed that age (71-<81 years, OR=1.607, 95%CI: 1.041-2.479; ≥81 years, OR=1.719, 95%CI: 1.040-2.842), educational level (middle school/technical secondary school, OR=0.616, 95%CI: 0.416-0.911), medical expense payment (employee medical insurance, OR=6.531, 95%CI: 2.030-21.010; resident medical insurance, OR=3.385, 95%CI: 1.095-10.466; public expense, OR=4.828, 95%CI: 1.700-13.712), vaccination willingness (yes, OR=6.237, 95%CI: 3.277-11.871), influenza vaccination history (yes, OR=14.600, 95%CI: 8.733-24.408) and vaccine literacy (medium and above, OR=2.412, 95%CI: 1.636-3.555) were associated with influenza vaccination among the elderly. Conclusion The influenza vaccination rate among the elderly was relatively low, and was mainly affected by age, educational level, medical expense payment, vaccination willingness, influenza vaccination history and vaccine literacy.

Objective To investigate the expressions of H3.3G34W,p63 and SATB2 in giant cell tumor of bone(GCTB)and the effect and value of their combined application in the diagnosis of GCTB.Methods We collected the samples and medical records of 54 cases of GCTB and 83 cases of non-giant cell tumor of bone(14 cases of aneurysmal bone cyst,16 cases of chondroblastoma and 53 cases of non-ossifying fibroma)diagnosed between 2020 and 2022 in the Department of Pathology of Honghui Hospital Affiliated to Xi'an Jiaotong University.The expressions of H3.3G34W,p63 and SATB2 were detected by EliVision immunohistochemical method.X2 test was used to determine whether there are significant differences in the positive rates of H3.3G34W,p63 and SATB2 among all the groups.The combined diagnostic model including H3.3G34W,p63 and SATB2 was established by Logistic regression analysis,and the diagnostic value of the model was evaluated by ROC curve analysis.Results The positive rates of H3.3G34W,p63 and SATB2 in GCTB group were 81.5％,90.7％and 92.6％,respectively;the positive rates in NGCTB group were 2.4％,28.9％and 62.7％.Compared with NGCTB group,the age of GCTB group was significantly older[(41.222±14.849)vs.(16.566±9.439),P＜0.001],and the prevalence was higher in women than in men(51.9％vs.48.1％,P＜0.001).In addition,compared with the NGCTB group,the positive rates of H3.3G34W(81.5％vs.2.4％,P＜0.001),p63(90.7％vs.28.9％,P＜0.001)and SATB2(92.6％vs.62.7％,P＜0.001)were significantly higher in the GCTB group.Univariate regression analysis built a univariate prediction modeland ROC curve analysis showed that age(AUC=92.9％,P＜0.001),sex(AUC=64.5％,P=0.004),H3.3G34W positive rate(AUC=89.5％,P＜0.001),p63 positive rate(AUC=80.9％,P＜0.001)and SATB2 positive rate(AUC=65.0％,P=0.003)were independent predictors of diagnosis of giant cell tumor of bone.Multivariate regression analysis(Logistic)constructed a hybrid prediction model.ROC curve analysis suggested that the hybrid model showed better prediction value than the single factor model(AUC=98.4％,P＜0.001).Conclusion H3.3G34W,p63 and SATB2 are effective molecular markers for the diagnosis of GCTB,and their combined application can improve the prediction efficiency of the diagnosis of GCTB.

Objective:To explore the feasibility and clinical effect of emergency lateral thigh muscle transfer in functional reconstruction of major traumatic muscle defects.Methods:Emergency surgeries for 8 patients(7 males and 1 female) with muscle defects were carried out subject to emergently reconstruct the power of lateral femoral muscle superficial region, between March 2020 and December 2021, in the Department of Hand and Foot Microsurgery Hospital, Xi'an Fengcheng Hospital. The 8 patients were 23 to 52 years old with an average of 37.6 years old. Five patients injured by machine crush, 2 by heavy object crush and 1 by traffic accident. Five patients were in Gustilo III B injury in forearm, including 2 with flexor muscle group defects, 2 with extensor muscle group defects and 1 with defect of dorsal metacarpal flexor muscle and extensor muscle. Among the 5 patients, 2 patients had the defects in left forearm and 3 in right forearm. One patient had defect of right 1st metacarpal bone and skin and thenar muscle. One patient suffered a complete right upper arm detachment with musculocutaneous nerve being drawn out from the bicipital muscle. One patient had Gustilo III C injury in the right calf with defects of extensor hallucis longus and extensor digitorum. The areas of soft tissue defect were 10.0 cm×8.0 cm-36.0 cm×11.0 cm and the size of flaps was 12.0 cm×6.0 cm-38.0 cm×12.0 cm with the volumes of excised muscle at 18.0 cm×9.0 cm×1.5 cm-10.0 cm×2.0 cm×1.0 cm. The anatomical cross-section and length of the corresponding muscle on the healthy side were measured by musculoskeletal ultrasound. The chimeric tissue flap was designed on the anterolateral side of the thigh. The flap was designed according to the size of the wound and the corresponding flap. Then 1 or 2 muscle tissue blocks were designed and cut from the superficial region of the lateral femoral muscle according to the condition of the muscle defect, to cover the wound and reconstruct the muscle power. Postoperative follow-ups were conducted by scheduled hospital visit. The contents of follow-up included dynamic observation, evaluation and record through musculoskeletal ultrasound, electromyography and strength of muscle.Results:For the 8 patients who were subject to a muscle reconstruction, the transferred muscles and flaps survived in stage-one without vascular event. Postoperative follow-ups lasted for 10 to 32 months with an average of 19.6 months. The strength of muscle was evaluated according to the M 4 strength of muscle. Strength of muscle restored to M 4 or above in 7 patients who could lift, hook or push a heavy object in 5-30 kg of weight, with free joint movement. One patient restored the strength of muscle to M 3+. Muscle contraction was detected 2-4 months after surgery by musculoskeletal B ultrasound. The average ratio of contraction to resting cross sectional area in 5 cases was 1.45±0.42. The shape of limb was bilaterally symmetrical. There was no discomfort in the donor site and knee joint. The flaps were soft and glossy, with protective sensation restored. Conclusion:Muscle transfer from the lateral femoral muscle superficial region in emergency surgery for functional reconstruction of traumatic muscle defects is feasible and effective with a good clinical effect.

Objective:To discuss outcomes of emergency repairing for Gustilo III B and III C fractures of forearm with complicated tissue defects and the related influence factors.Methods:From January 2014 to Feburary 2022, data of 98 cases of Gustilo III B and III C fractures with large compound defects of soft tissue, blood vessel, bone, tendon or muscle from elbow to wrist were collected. Primary debridement, bone fixation, wound coverage by free flap, bone transfer(or bone cement filling) or dynamic reconstruction of muscle were completed with emergency surgery in Department of Hand and Foot Microsurgery, Xi'an Fengcheng Hospital. Postoperative follow-ups were conducted through outpatient clinic visits, telephone and WeChat reviews. Video clips, questionnaires and the latest information of patients were also analysed. Rank sum test and Chi-square test were used to examine the relationship between independent variables such as general condition, disease condition and surgical procedures of chimeric tissue transfer group and simple flap transfer group, together with dependent variables such as limb salvage, number of surgery, wound healing, function scores, and complications. P<0.05 were further included in the regression equation to discover the relationship between multiple independent variables and dependent variables. Results:Follow-up lasted for 6-96 months, with an average of 71.1 months. In the chimeric group, the limb salvage rate was at 95.1%, with an infection rate of 8.50% and an average number of surgery was 2.13±0.89. In the simple flap transfer group, the limb salvage rate was at 87.5%, with an infection rate of 15.38% and an average number of surgery was 2.62±0.64. The good rate of Anderson score was 65.3% and the average score of Disability of the Arm, Shoulder and Hand(DASH) was 32.9(0-60) points for all the patients. There were significant differences in dependent variables of limb salvage and infection rate between the 2 groups ( P<0.05). Ischemia time and method of bone fixation led to significant differences in number of surgery ( P<0.05). Methods of bone fixation and the types of flap made significant differences in wound healing ( P<0.05). Underlying disease, bonedefect, Gustilo classification and method of bone fixation all contributed to the significant differences in function score ( P<0.05 or P<0.01) . Conclusion:Emergency surgery for repair of serious injury of forearm has a relatively high limb salvage rate and good functional effects. The limb salvage rate is not correlated with independent variables such as severity of injury, Mangledextremity Severity Score (MESS) and ischemia time, while transfer of a simple flap or a chimeric flap is significantly correlated with the limb salvage rate, infection and wound healing. The severity of injury, ischemia time and bone defect are correlated with functional assessment, number of surgery and bone healing.

Hip fractures are among the most common fractures in the elderly, presenting to be a leading cause of disability and mortality. Surgical treatment is currently the main treatment method for hip fractures. The incidence of perioperative malnutrition is increased after hip fractures in the elderly due to the comorbidities, decreased basal metabolic rate, accelerated protein breakdown, weakened anabolism and surgical stress. However, malnutrition not only increases the incidence of postoperative complications, but also leads to increased mortality, indicating an important role of perioperative nursing management of nutrition for the elderly patients with hip fractures. At present, there still lacks scientific guidance and application standards on perioperative nursing management of nutrition for the elderly patients with hip fractures. Therefore, the Orthopedic Nursing Committee of Chinese Nursing Association and the Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Expert consensus on perioperative nursing management of nutrition for elderly patients with hip fractures ( version 2023) according to evidence-based medical evidences and their clinical experiences. Fourteen recommendations were made from aspects of nutrition screening, nutrition assessment, nutrition diagnosis, nutrition intervention and nutrition monitoring to provide guidance for perioperative nursing management of nutrition in elderly patients with hip fractures.

Objective:To explore the feasibility in reconstruction of the muscular power with the superficial part of lateral femoral muscle through anatomical study on the superficial region of lateral femoral muscle.Methods:Studies on 4 sides of lower limbs of 2 cadaver specimen were conducted in the Department of Hand and Foot Microsurgery of Xi'an Fengcheng Hospital. Intraoperative observations and measurements were further carried out on 21 sides of 21 patients. Muscular fascia in superficial region, muscular gross morphology, thickness, length and width of muscles, length of muscle fibres and pinnate angles of muscle surface were observed and measured. Both blood vessels and nerves in the muscle were separated to measured.Results:The superficial region of lateral femoral muscle was in a shape of fusiform and started from the greater trochanter and ended at the patella and rectus femoris, with the fascia at proximal end and the muscle of distal end. The inferior muscle fibres of the fascia were arranged in sequence and ended at the deep fascia from proximal to distal. Mean muscle thickness was measured at 1.96 cm±0.48 cm, and mean pinnate angle was of 18.9°±3.3°. The superficial region was found being distributed by the descending branches of lateral circumflex femoral artery(LCFA) and the second branch of femoral nerve, and they accompanied each other. At 5.0 cm from the point of entry to the muscle, the diameter of the vessels was measured at 2.39 mm±0.52 mm, and the diameter of nerves was at 2.64 mm±0.61 mm. Both of arteries and nerves further branched out anteriorly and posteriorly in 1.0-1.5 cm intervals after having entered the muscle. At 0 - 2.5 cm away from the muscle entry point, a larger branch was often running posteriorly into the muscle, and this branch appears on all 4-sided specimens. While the occurrence rate in the 21 sides of patients observed in operations was of 90.5%, with a transverse diameter at 1.23 mm±0.28 mm.Conclusion:The superficial region of lateral femoral muscle is dominated by independent vessels and nerves and there are many branches from superior vessels and nerves, which form an anatomical basis for one or more muscular flaps.

Objective:To explore the feasibility of functional reconstruction of muscle power in treatment of traumatic muscle defects by transferring part of superficial vastus of lateral thigh.Methods:From March 2020 to March 2023, reconstruction of muscle power with transfer of superficial lateral thigh muscle was performed on 9 patients in the Department of Hand and Foot Microsurgery of Xi'an Fengcheng Hospital. Nine patients were assigned in a study group. A total of 48 patients who previously had the surgery of chimerically grafted superficial vastus of lateral thigh were recruited as the "previous surgery group" and another group of 71 staff volunteers from our hospital were recruited as the "healthy control group". Of the study group, 5 patients had Gustilo type ⅢB injury in forearm (two with defects of flexor muscle group and 3 with extensor muscle group, 2 with the defects in the left and 3 in the right), one had defect of both flexor and extensor muscle groups in dorsal hand, one had defect of right 1st metacarpal with defects of soft tissue and thenar muscle, one had a completely severed right upper arm with a withdrawn musculocutaneous nerve from the biceps brachii and one had Gustilo ⅢC injury in right calf with defects of tibialis anterior, extensor longus and extensor phalangeal muscle. In the emergency surgery, part of the superficial muscles of lateral thigh were taken to reconstruct the muscular power for the defected traumatic muscles. During the surgery, the excessed nerve with a length of 3.0 cm proximally was removed at 3.0 cm from the point where the nerve entered the muscle. In the transfer of superficial chimeric muscle of lateral thigh, a 3.0 cm of sample nerve tissue was taken for HE staining to find out the number of nerve fibers. Musculoskeletal ultrasonography, electromyography and muscle strength test were performed in the postoperative follow-up for observations and evaluations of the effects of surgery. Average length and thickness of muscle were taken from the 48 patients in the "previous surgery group". The measurement was compared with the length of muscle fibers and the number of nerve fibers in the gracilis muscle of the 9 patients in study group. The cross-sectional areas (SCA) at contraction state (C) and resting state (R) of the superficial vastus of lateral thigh were taken from the 71 volunteers in the healthy control group, and the C/R ratio was calculated (CR value). All the 9 patients were included in the postoperative follow up by outpatient visits and via telephone or internet reviews to observe the recovery of muscle strength of the reconstruction of muscle dynamics.Results:In the study group, the number of nerve fibers shown by immunohistochemical HE staining was 1 088±213, with the CR value of graft muscle measured by musculoskeletal ultrasonography at 1.44±0.17. The wound healed smoothly without complication. The average time of postoperative follow-up for the 9 patients was 22.6 (10-38) months. Recovery of muscle strength was found at M5 in 6 patients and M4 in 3 patients. The appearance of the joints was normal. In the previous surgery group, the average muscle thickness of the superficial vastus lateralis muscle was 1.74 cm±0.35 cm and the length of muscle fiber was 8.86 cm±1.59 cm. In the healthy control group, the CR value of the superficial muscle vastus of lateral thigh was found at 1.17±0.12.Conclusion:Reconstruction of muscular power with partial muscle transfer of the superficial vastus of lateral thigh is proposed in this study.
