Objective:To observe the effects of modified Taohong Siwu Decoction on peripheral circulation status of affected limbs and serum thromboxane B 2 (TXB 2) and prostacyclin (PGI 2) levels in patients with traumatic limb fractures after open reduction and internal fixation. Methods:Randomized controlled trial study was conducted. 70 patients with traumatic limb fractures who underwent open reduction and internal fixation in the hospital from February 2020 to February 2023 were set as observation subjects and divided into control group (34 cases) and observation group (36 cases) according to the order of hospitalization. The control group was given conventional method for treatment, and the observation group was given modified Taohong Siwu Decoction adjuvant therapy on the basis of the control group. The treatment for both groups lasted for 2 weeks. TCM symptoms scores were evaluated before and after treatment. Ankle brachial index (ABI) was detected using a Doppler blood flow detector. Color Doppler ultrasound was used to detect the inner diameter, blood flow, and deep veins of the affected limb; serum levels of TXB 2 and PGI 2 were detected by ELISA. Results:After treatment, the total effective rate of clinical efficacy was 91.67% (33/36) in observation group and 73.53% (25/34) in control group, with statistical significance ( P<0.05). After treatment, the observation group had lower scores for qi and blood stasis (2.13 ± 0.43 vs. 3.61 ± 0.96, t=5.85), tendon and bone injury (1.62 ± 0.41 vs. 2.74 ± 0.58, t=9.37), swelling and ecchymosis (1.15 ± 0.31 vs. 2.28 ± 0.52, t=1.12), and liver and kidney deficiency (1.52 ± 0.24 vs. 2.15 ± 0.36, t=8.66) compared to the control group ( P<0.001); after treatment, the ABI (0.83 ± 0.03 vs. 0.74 ± 0.02, t=14.68), vascular diameter [(0.48 ± 0.13) mm vs. (0.42 ± 0.11) mm, t=2.08], and blood flow velocity [(60.24 ± 15.46) cm/s vs. (52.15 ± 12.11) cm/s, t=2.41] in the observation group were higher than those in the control group ( P<0.01 or P<0.05). After treatment, the serum TXB 2 levels [(140.76 ± 16.64) ng/L vs. (168.39 ± 25.28) ng/L, t=5.37] and TXB 2/PGI 2 (6.67 ± 1.24 vs. 9.33 ± 1.69, t=7.54) in the observation group were lower than those in the control group ( P<0.01); the level of PGI 2 [(21.27 ± 2.24) ng/L vs. (18.71 ± 1.79) ng/L, t=5.26] was higher in the control group ( P<0.01). The incidence of deep vein thrombosis after treatment in the observation group was 19.44% (7/36), while in the control group it was 44.12% (15/34), with statistical significance ( χ 2=4.94, P=0.026). Conclusion:Modified Taohong Siwu Decoction adjuvant therapy can enhance the clinical efficacy of patients with traumatic limb fractures after open reduction and internal fixation, relieve the TCM symptoms, improve the peripheral circulation status of affected limbs, reduce the postoperative hypercoagulability and prevent the deep venous thrombosis formation.

OBJECTIVE: To investigate the effectiveness of medial and lateral column periosteal hinge reconstruction using Kirschner wire in the closed reduction of multi-directional unstable humeral supracondylar fractures in children. METHODS: A clinical data of 43 children with multi-direction unstable humeral supracondylar fractures, who met the selection criteria and were admitted between August 2020 and August 2022, was retrospectively analyzed. Twenty-one cases of fractures were treated wuth closed reduction after medial and lateral column periosteal hinge reconstruction using Kirschner wire and percutaneous Kirschner wires fixation (study group), while 22 cases of fractures were treated by traditional closed reduction technique and percutaneous Kirschner wire fixation (control group). There was no significant difference in gender, age, cause of injury, fracture side, and interval from injury to operation between the two groups ( P>0.05). The operation time, intraoperative fluoroscopy times, the number of children who were changed to open reduction after closed reduction failure, fracture healing time, complications within 2 months after operation, and the Flynn score of elbow joint function at last follow-up were compared between the two groups. RESULTS: All the fractures in the study group were successfully closed reduction, and 4 cases in the control group were changed to open reduction and completed the operation, the difference between the two groups was significant ( P=0.040). The operation time and intraoperative fluoroscopy times of the study group were significantly less than those of the control group ( P<0.05). All children in both groups were followed up 6-18 months with an average of 9.0 months in the study group and 9.8 months in the control group. Imaging review showed that the fractures of both groups healed, and the difference in the healing time between the two groups was not significant ( P=0.373). According to Flynn score at last follow-up, the excellent and good rate of elbow joint function was 95.2% (20/21) in the study group and 86.4% (19/22) in the control group, with no significant difference ( P=0.317). There was no complication such as infection or irritation at the end of Kirchner wire within 2 months after operation. CONCLUSION For children with multi-directional unstable humeral supracondylar fractures, the use of Kirschner wires to reconstruct the medial and lateral column periosteal hinge to assist in closed reduction has the advantages of shortening operation time, reducing intraoperative fluoroscopy times, and effectively reducing the incidence of open reduction, and can achieve similar postoperative elbow joint function when compared with traditional closed reduction technique.

OBJECTIVE: To investigate the short-term effectiveness of ultrasound-guided closed reduction by Kirschner wire provocation technique in the treatment of Salter-Harris types Ⅰ and Ⅱ periosteal entrapment of distal tibial epiphyseal fractures in children and adolescents. METHODS: Between May 2019 and May 2022, 41 patients with Salter Harris types Ⅰ and Ⅱ distal tibial epiphyseal fractures were admitted, all of whom had periosteal entrapment on preoperative MRI, and 38 cases (92.7%) were confirmed to have periosteal entrapment by intraoperative ultrasound. There were 24 males and 14 females, the age ranged from 6.8 to 15.7 years, with an average of 10.7 years; and there were 20 cases of Salter Harris type Ⅰ and 18 cases of type Ⅱ. The time from injury to operation was 22-76 hours, with an average of 28.4 hours. The preoperative imaging examination showed excellent alignment in 4 cases, good in 20 cases, and poor in 14 cases. The ultrasound guided Kirschner wire provocation technique for closed reduction and percutaneous Kirschner wire internal fixation were performed. The operation time, intraoperative fluoroscopy frequency, fracture healing time, and complications were recorded. Anteroposterior and lateral X-ray films of the affected ankle joint were taken before operation, at 3 months after operation, and at last follow-up to observe the healing of the fracture, and anteroposterior X-ray films of the whole length of both lower limbs were taken to evaluate the alignment of the force lines of the affected limbs. The range of motion (ROM), visual analogue scale (VAS) score, and American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score were used to evaluate ankle function. The mechanical lateral distal tibia angle (mLDTA) and the anatomic anterior distal tibia angle (aADTA) were measured. RESULTS: The operation time ranged from 17 to 52 minutes, with an average of 22.6 minutes, and the intraoperative fluoroscopy frequency ranged from 3 to 11 times, with an average of 4.2 times. X-ray examination during operation and at 2 days after operation showed that anatomical reduction was achieved. All patients were followed up 10-24 months, with an average of 16.4 months. All fractures healed in 6.1-7.2 weeks, with an average of 6.3 weeks; no fracture displacement occurred, and the patients recovered to their pre-injury level of motion at 6 months after operation. Needle tail irritation occurred in 2 cases at 4 weeks after operation, and they recovered after symptomatic treatment. During the follow-up, there was no serious complication such as incision deep infection, bone nonunion, delayed union, and malunion. At last follow-up, the patients' alignment were all excellent, and the difference was significant when compared with preoperative one ( Z=-7.471, P<0.001). The VAS score, AOFAS ankle-hindfoot score, dorsiflexion-plantar flexion ROM, varus-valgus ROM, mLDTA, and aADTA significantly improved at 3 months after operation and last follow-up when compared with preoperative ones ( P<0.05). CONCLUSION Ultrasound-guided closed reduction by Kirschner wire provocation technique for treating Salter-Harris types Ⅰ and Ⅱ periosteal entrapment of distal tibial epiphyseal fractures in children and adolescents is minimally invasive and safe.

Objective:To compare the effects of anterograde elastic stable intramedullary nailing (ESIN-A), retrograde K-wires fixation (KW-R) and retrograde precision shaping of elastic stable intramedullary nailing (ESIN-RPS) in the treatment of fractures of distal radial metaphyseal diaphyseal junction (DRMDJ) in children.Methods:A retrospective study was conducted to analyze the data of 112 eligible children with DRMDJ fracture who had been treated at Department of Orthopedics, Children's Hospital, Anhui Medical University and Department of Orthopedics, The People's Hospital of Fuyang City,Anhui Medical University, from January 2016 to May 2022. There were 64 males and 48 females, with an age of (8.4±2.3) years. The children were divided into 3 groups according to different surgical fixation methods: group ESIN-A of 36 cases, group KW-R of 52 cases, and group ESIN-RPS of 24 cases. The operation time, intraoperative bleeding, fluoroscopy times, alignment rates and residual angulations by the anteroposterior and lateral X-ray films immediately after reduction were compared among the 3 groups. The Gartland-Werley evaluation of wrist function and complications were compared at the last follow-up.Results:There was no statistically significant difference in the preoperative general data among the 3 groups, indicating comparability ( P>0.05). In the operation time, group KW-R [(71.2±9.2) min] > group ESIN-A [(65.1±13.1) min] > group ESIN-RPS [(51.7±17.1) min]; in the fluoroscopy times, group KW-R [(13.9±6.3) times] > group ESIN-A [(9.0±2.8) times] > group ESIN-RPS [(6.4±2.0) times]; in the alignment rates by the anteroposterior and lateral X-ray films immediately after reduction, group ESIN-RPS (93.1%±4.6% and 95.2%±3.3%) > group KW-R (82.1%±11.0% and 88.1%±7.4%) > group ESIN-A (80.4%±9.9% and 86.7%±6.9%); in the residual angulations by the anteroposterior and lateral X-ray films immediately after reduction, group ESIN-RPS (3.3°±1.8° and 2.9°±2.1°) < group ESIN-A (5.2°±1.0° and 5.0°±3.2°) < group KW-R (6.6°±1.6°and 7.5°±2.7°). Pairwise comparisons in the above items were statistically significant ( P<0.05). In group ESIN-A, the incision length [(1.8±0.3) cm] was significantlylonger than that in group ESIN-RPS [(1.4±0.2) cm], and the intraoperative blood loss [(8.3±2.2) mL] significantly larger than that in group ESIN-RPS [(5.5±1.6) mL] ( P<0.05). One year after operation, the excellent and good rate by the Gartland-Werley evaluation of wrist function in groups ESIN-RPS, ESIN-A and KW-R, respectively, were 95.8% (23/24), 86.5% (31/36) and 86.1% (46/52), showing no statistically significant difference between the 3 group ( P>0.05), and the major incidence of complications in group KW-R (25.0%, 13/52) and in group ESIN-A (25.0%, 9/36) were significantly higher than that in group ESIN-RPS (4.2%, 1/24) ( P<0.05). Conclusion:In the treatment of DRMDJ fractures in children, compared with ESIN-A and KW-R, ESIN-RPS is an effective choice due to its advantages of shorter operation time, less intraoperative blood loss, less radiation, better alignment, and fewer complications.

Objective: To understand social anxiety and relevant factors among graduate students under the normalization stage of COVID-19 epidemic prevention and control. Methods: Using convenience sampling method, an online questionnaire survey on graduate students from 5 universities in Jiangsu Province was conducted. Measurements used in the survey includes General Self Efficacy Scale (GSES), General Alienation Scale (GAS), Interaction Anxiousness Scale (IAS) and self made survey for basic information and household living conditions. Results: The overall score of graduate students self efficacy was (2.58±0.50). Average score was (30.68±6.22) for alienation, and (47.55±8.77) for interaction anxiety, with detection rate of social anxiety being 43.96%. Increased dependence on smartphones and electronic devices ( OR=1.86, 95%CI =1.32-2.61) and high alienation score (medium level: OR=2.06, 95%CI =1.45-2.92; high level: OR=5.19, 95%CI =1.00-27.00) were positively correlated with social anxiety. Increased communication with friends ( OR=0.65, 95%CI =0.47-0.90 and high self efficacy (medium level: OR= 0.37 , 95%CI =0.21-0.66; high level: OR=0.15, 95%CI =0.08-0.30) were negatively correlated with social anxiety. Conclusion At the normalization stage of COVID-19 epidemic prevention and control, social anxiety of graduate students is one of the mental health issues which need further attention. Participation in peer support helps prevent social anxiety through developing self efficacy, alleviating individual alienation, and reducing dependence on electronic devices among graduate students.

Objective To analyze the related risk factors affecting the prognosis of elderly patients with severe community acquired pneumonia (SCAP). Methods A retrospective study method was conducted; the elderly (≥ 75 years old) patients with SCAP treated in the First Affiliated Hospital of Hainan Medical College from January 2015 to January 2019 were enrolled. The general data of patients were collected, including sex, age, oxygenation index (PaO2/FiO2), involved organs, presence or absence of following diseases or treatment: damage in multiple lung lobes, septic shock, basic diseases (cardiovascular disease, chronic lung disease, diabetes, hypertension, and cerebrovascular disease), invasive mechanical ventilation, ventilator-associated pneumonia (VAP), misinhalation event, hyponatremia, respiratory acidosis, hypoproteinemia, intubation times, total mechanical ventilation time, etc. According to the prognosis, the patients were divided into a death group and a survival group. The general data were compared between the two groups with different prognoses. Single factor analysis was carried out by selecting variables. The indicators with statistical significant differences in the results of univariate analysis were introduced into the multivariate Logistic regression analysis to analyze the related risk factors affecting the prognosis of elderly patients with SCAP. The receiver operating characteristic (ROC) curve was drawn to analyze the predictive values of risk factors in the patients with SCAP.

Univariate analysis showed that the following factors were higher in the death group than those in the survival group: organ involvement >2 [69.70% (23/33) vs. 35.44% (28/79)], lung lobe damage ≥ 3 [75.76% (25/33) vs. 51.90% (41/79)], invasive mechanical ventilation [72.73% (24/33) vs. 32.91% (26/79)], diabetes [30.30% (10/33) vs. 12.66% (10/79)], intubation times ≥2 [57.58% (19/33) vs. 48.10% (38/79)], hypoproteinemia [75.76% (25/33) vs. 41.77% (33/79)], hyponatremia [72.73% (24/33) vs. 48.10% (38/79)], respiratory acidosis [66.67% (22/33) vs. 44.30 %(35/79)] and total mechanical ventilation time ≥ 15 days [69.70% (23/33) vs. 40.51 (32/79)]; the factors in the death group lower than those in the survival group were: septic shock [3.03% (1/33) vs. 17.72% (14/79)], chronic lung disease [6.06% (2/33) vs. 25.32% (20/79)] and PaO2/FiO2 [mmHg (1 mmHg = 0.133 kPa): 102.89±14.78 vs. 109.56±14.08],the differences were statistically significant (all P < 0.05); there were no significant differences in gender, age, cardiovascular disease, hypertension, VAP, misinhalation events and cerebrovascular disease between the two groups (all P > 0.05). Multivariate Logistic regression analysis showed that diabetes mellitus [odds ratio (OR) = 1.074, 95% confidence interval (95%CI) = 1.017-1.287, P =0.045], septic shock (OR = 2.765, 95%CI = 1.083-3.411, P = 0.047), hyponatremia (OR = 1.792, 95%CI = 1.128-1.417, P = 0.006), hypoalbuminemia (OR = 2.187, 95%CI = 1.872-5.462, P = 0.046), invasive mechanical ventilation (OR = 5.870, 95%CI = 2.324-23.796, P = 0.001), respiratory acid poisoning (OR = 2.934, 95%CI = 2.454-7.275, P = 0.043), time of mechanical ventilation (OR= 1.986, 95%CI = 2.467-3.483, P = 0.034), number of intubation (OR = 6.760, 95%CI = 2.116-24.696, P = 0.001), PaO2/FiO2 (OR = 1.981, 95%CI = 1.006-1.417, P = 0.007), organ involvement > 2 (OR = 2.924, 95%CI = 2.534-6.285, P = 0.048), chronic lung disease (OR = 2.887, 95%CI = 1.487-3.483, P = 0.039), and lung lobe damage≥3 (OR = 2.754, 95%CI = 1.131-1.798, P = 0.045) were independent risk factors affecting the prognosis of elderly patients with SCAP. ROC analysis showed that hyponatremia, hypoalbuminemia, invasive mechanical ventilation, total mechanical ventilation time, PaO2/FiO2, organ involvement > 2, damage of lung lobes ≥ 3, had predictive values for the prognosis of SCAP [the areas under ROC curve (AUC) were 0.377, 0.267, 0.301, 0.646, 0.650, 0.329, and 0.381, respectively, all P < 0.05]. Conclusions Underlying disease, invasive mechanical ventilation, respiratory acidosis, total mechanical ventilation time, PaO2/FiO2, intubation times ≥ 2, chronic lung disease and lung damage≥ 3 lobes are the independent risk factors for the prognosis of elderly patients with severe community acquired pneumonia. Clinical treatment should focus on the above aspects to minimize the mortality of patients.
