OBJECTIVE To analyze the influential factors for clinical efficacy of polymyxin B combined with other antibiotics in the treatment of carbapenem-resistant Acinetobacter baumannii （CRAB） pulmonary infection. METHODS A retrospective analysis was conducted on the clinical data of patients with CRAB pulmonary infection in our hospital from May 2021 to October 2024. Information such as age， gender， admitting department， infection status， underlying medical conditions， mechanical ventilation time， combination anti-infective treatment regimens， and the Acute Physiology and Chronic Health Evaluation Ⅱ （APACHE-Ⅱ） score 24 h before medication was compiled. Based on the effectiveness of the treatment， patients were divided into treatment-effective group and treatment-ineffective group. Univariate analysis and multivariate Logistic regression analysis were employed to identify independent factors influencing clinical efficacy. RESULTS A total of 156 patients were included， and 108 patients were treated effectively， with an effective rate of 69.23%. The results of univariate analysis indicated that there were statistically significant differences between 2 groups in terms of the duration of mechanical ventilation time， APACHE-Ⅱ score 24 h before medication， the number of complication types， the proportion of abnormal coagulation function， anti-infective treatment course， and hospital stay before medication （P＜0.05）. The results of multivariate Logistic regression analysis showed that APACHE-Ⅱ score≥15 points 24 h before medication [OR＝2.965， 95%CI （1.284， 6.845）， P＝0.020]， mechanical 20251606） ventilation time≥10 d [OR＝3.577， 95%CI （1.185， 10.793）， P＝0.037] and hospital stay≥14 d before medication [OR＝2.422， 95%CI （1.036， 5.654）， P＝0.041] were independent 15120420253@139.com risk factors， and anti-infective treatment course＞7 d was a protective factor [OR＝0.445， 95%CI （0.221， 0.895）， P＝0.043]. CONCLUSIONS This study shows that the effective rate of polymyxin B combined with other antibiotics in the treatment of CRAB pulmonary infection is less than 70%. The mechanical ventilation time≥10 d， APACHE-Ⅱ score≥15 points 24 h before medication， and hospital stay≥14 d before medication may lead to treatment failure， whereas anti-infective treatment course＞7 d may be associated with treatment success.

Objective: To evaluate the effectiveness of "Internet plus" continuous intervention on psychological status and nursing satisfaction of patients with depression after hospital discharge, so as to provide the reference for reducing the recurrence risk of patients with depression and improving the quality of life. Methods: From January to December 2024, patients with mild to moderate depression who were hospitalized in a tertiary grade-a mental health specialized hospital in Wenzhou City and met the discharge criteria were selected as the research objects. The patients were divided into the control group and the intervention group according to a ratio of 1∶1 by the random number table method. Hamilton Depression Scale, Hamilton Anxiety Scale, and Nursing Satisfaction Questionnaire were used to evaluate depressive symptoms, anxiety symptoms, and nursing satisfaction before and after intervention. Covariance analysis was used to compare the differences between the two groups before and after the intervention. Results: A total of 62 patients with mild to moderate depression were enrolled, with 31 patients in the intervention group and 31 patients in the control group. Before the intervention, there were no statistically significant differences in gender, age, course of disease, educational level, marital status, depression symptoms score, anxiety symptoms score, and nursing satisfaction score between the two groups (all P>0.05). After the intervention, the scores of depression and anxiety symptoms in the intervention group decreased by 8.87 and 5.01 points, respectively, compared with those before the intervention, and the scores of depression and anxiety symptoms in the control group decreased by 2.52 and 1.16 points, respectively (all P<0.05). After the intervention, the scores of depression and anxiety symptoms in the intervention group decreased more than those in the control group (both P<0.05). The nursing satisfaction score of the intervention group increased by 6.57 points on average compared with that before the intervention, and that of the control group increased by 4.23 points on average (both P<0.05). There was no statistically significant difference in the increase of nursing satisfaction scores between the two groups before and after intervention (P>0.05). Conclusion The "Internet plus" continuous intervention has a good effect on improving the depressive symptoms and anxiety symptoms of patients with depression after haspital discharge, which can consolidate the treatment effect and improve nursing satisfaction.

OBJECTIVE: To compare the biomechanical properties of personalized Y-shaped plates with horizontal plates, vertical plates, and traditional Y-shaped plates in the treatment of distal humeral intra-articular fractures through finite element analysis, and to evaluate their potential for clinical application. METHODS: The study selected a 38-year-old male volunteer and obtained a three-dimensional model of the humerus by scanning his upper limbs using a 64-slice spiral CT. Four types of fracture-internal fixation models were constructed using Mimics 19.0, Geomagic Wrap 2017, Creo 6.0, and other software: horizontal plates, vertical plates, traditional Y-shaped plate, and personalized Y-shaped plate. The models were then meshed using Hypermesh 14.0 software, and material properties and boundary conditions were defined in Abaqus 6.14 software. AnyBody 7.3 software was used to simulate elbow flexion and extension movements, calculate muscle strength, joint forces, and load torques, and compare the peak stress and maximum displacement of the four fixation methods at different motion angles (10°, 30°, 50°, 70°, 90°, 110°, 130°, 150°) during elbow flexion and extension. RESULTS: Under dynamic loading during elbow flexion and extension, the personalized Y-shaped plate exhibits significant biomechanical advantages. During elbow flexion, the peak internal fixation stress of the personalized Y-shaped plate was (28.8±0.9) MPa, which was significantly lower than that of the horizontal plates, vertical plates, and traditional Y-shaped plate ( P<0.05). During elbow extension, the peak internal fixation stress of the personalized Y-shaped plate was (18.1±1.6) MPa, which was lower than those of the other three models, with significant differences when compared with horizontal plates and vertical plates ( P<0.05). Regarding the peak humeral stress, the personalized Y-shaped plate model showed mean values of (10.9±0.8) and (13.1±1.4) MPa during elbow flexion and extension, respectively, which were significantly lower than those of the other three models ( P<0.05). Displacement analysis showed that the maximum displacement of the humerus with the personalized Y-shaped plate during elbow flexion was (2.03±0.08) mm, slightly higher than that of the horizontal plates, but significantly lower than that of the vertical plates, showing significant differences ( P<0.05). During elbow extension, the maximum displacement of the humerus with the personalized Y-shaped plate was (1.93±0.13) mm, which was lower than that of the other three models, with significant differences when compared with vertical plates and traditional Y-shaped plates ( P<0.05). Stress contour analysis showed that the stress of the personalized Y-shaped plate was primarily concentrated at the bifurcation of the Y-shaped structure. Displacement contour analysis showed that the personalized Y-shaped plate effectively controlled the displacement of the distal humerus during both flexion and extension, demonstrating excellent stability. CONCLUSION The personalized Y-shaped plate demonstrates excellent biomechanical performance in the treatment of distal humeral intra-articular fractures, with lower stress and displacement, providing more stable fixation effects.

OBJECTIVE: To investigate the surgical method and short-term effectiveness of arthroscopy edge-to-edge #-shaped suture in the treatment of the complete radial tear of the lateral meniscus body. METHODS: The clinical data of 13 patients with complete radial tear of lateral meniscus body between May 2020 and August 2023 were retrospectively analyzed. There were 10 males and 3 females, aged 15-38 years (mean, 24.2 years). There were 11 cases of acute injury and 2 cases of chronic injury, with time from injury to admission ranging from 2 days to 5 months. All patients had tenderness in the lateral joint space, and 2 patients with chronic injury had positive McMurray's sign. All patients were treated with arthroscopic edge-to-edge #-shaped suture technique. The knee joint activity and tenderness in the lateral joint space were detected, and the healing of the incision and the occurrence of complications were observed. X-ray films and MRI of the knee joint were performed to evaluate joint degeneration and meniscus healing. Lysholm score, International Knee Documentation Committee (IKDC) subjective score, Tegner score, and visual analogue scale (VAS) score were used to evaluate the functional recovery before and after operation. RESULTS: The operation time ranged from 46 to 100 minutes (mean, 80.08 minutes). All the incisions healed by first intention, and no complication such as intraoperative vascular and nerve injury or postoperative infection occurred. All 13 patients were followed up 20-59 months (mean, 29.3 months). All patients had no limitation of knee extension and flexion. One patient with chronic injury continued to have tenderness in the lateral space of the knee joint, while the remaining patients had no tenderness, swelling, and locking in the lateral space. Immediate postoperative MRI of knee joint showed continuous recovery of the lateral meniscus. At last follow-up, no degenerative changes were observed in X-ray films of knee joint. Except for 1 patient with chronic injury, the MRI of the other patients showed the healing performance after lateral meniscus suture. Lysholm score, IKDC subjective score, Tegner score, and VAS score all significantly improved when compared with those before operation (P<0.05). CONCLUSION The edge-to-edge #-shaped suture technique can effectively repair the complete radial tear of the lateral meniscus body, and the short-term effectiveness is satisfactory.

Objective: To construct a prediction model of non-alcoholic fatty liver disease (NAFLD) in middle-aged and elderly patients with type 2 diabetes mellitus (T2DM), so as to provide basis for early screening and prevention of T2DM complicated with NAFLD. Methods: Patients aged 45 years and above and diagnosed with T2DM in Karamay Hospital of People's Hospital of Xinjiang Uygur Autonomous Region in 2021 were collected as the study subjects. The data of general demographic characteristics and biochemical test results were collected. The patients were randomly divided into training group (n=3 241) and validation group (n=1 389) according to the ratio of 7∶3. LASSO regression and multivariable logistic regression model were used to select predictive factors. The nomograph model for prediction of NAFLD risk in T2DM patients was established. The predictive value of the model was evaluated using the receiver operating characteristic (ROC), adjusted curve and decision clinical analysis. Results: Totally 4 630 T2DM cases were included, including 1 279 cases (27.62%) complicated with NAFLD. LASSO regression and multivariable logistic regression analysis identified gender, age, diastolic blood pressure, body mass index, alanine transaminase, triglycerides, low density lipoprotein cholesterol and platelet count as risk prediction factors for NAFLD in T2DM patients. The area under the ROC curve was 0.823 (95%CI: 0.814-0.832) for the training group and 0.809 (95%CI: 0.799-0.818) for the validation group, and Hosmer-Lemeshow test showed a good fitting effect (P>0.05). Decision curve analysis showed higher net clinical benefit of using the predictive model to predict NAFLD risk when the risk threshold probability was 0.27 to 0.85. Conclusion The nomogram model established has a good predictive value for the risk of NAFLD in T2DM patients aged 45 years and above.

Objective To explore the application value of stage rehabilitation intervention under the Health action process approach(HAPA)model(SRI-HAPAM)combined with tranexamic acid(TXA)in elderly patients with femoral neck fracture(FNF)undergoing total hip arthroplasty(THA).Methods Elderly FNF patients with unilateral THA in the First Affiliated Hospital of Wenzhou Medical University from December 2022 to June 2023 were enrolled.According to the random number table method,the patients were divided into routine nursing(RN)group and TXA+SRI-HAPAM group.The RN group received conventional treatment after surgery,and the TXA+SRI-HAPAM group received TXA combined with SRI-HAPAM after surgery.The bleeding indexes[hidden blood loss(HBL),explicit blood loss(EBL)and blood transfusion volume(BTV)],and the levels of hemoglobin(Hb),C-reactive protein(CRP)and D-dimer(DD)were compared between the two groups at 24 h after surgery.The hip function[joint deformity(JD),joint function(JF),joint pain(JP),joint motion(JM)and total hip function(THF)],anxiety and depression[self-rating anxiety scale and self-rating depression scale],satisfaction with care,and complications were compared between the two groups at 3 months after surgery.Results A total of 100 elderly patients with unilateral THA due to FNF were included in the study,including 54 in the TXA+SRI-HAPAM group and 46 in the RN group.Before operation,there was no significant difference in Hb,CRP,DD,JD,JF,JP,JM,THF and SAS between the two groups(P>0.05).At 24 hours after operation,Hb decreased in the two groups,while CRP and DD increased(P<0.05),and the decrease in Hb and the increase in CRP and DD,as well as HBL,EBL and BTV in the TXA+SRI-HAPAM group,were lower than those in the RN group(P<0.05).At 3 months after operation,JD,JF,JP,JM and THF in both groups increased compared with those before operation,while SAS and SDS decreased compared with those before operation(P<0.05),and the functional scores of JD,JF,JP,JM and THF in the TXA+SRI-HAPAM group were significantly higher than those in the RN group,and the scores of SAS and SDS were lower than those in the RN group(P<0.05).3 months after surgery,the nursing satisfaction of the TXA+SRI-HAPAM group was significantly higher than that of the RN group,and the total complication rate was lower than that of the RN group(P<0.05).Conclusion Compared the Routine nursing,TXA combined with SRI-HAPAM more effectively promotes postoperative recovery in patients with THA.

Objective:To investigate urinary pH distribution and its influencing factors in gout patients, to provide insights for individualized treatment.Methods:This is a retrospective study. The gout patients in the Gout Outpatient Department of the Affiliated Hospital of Qingdao University from September 2019 to August 2021 were collected. Clinical data were collected and relevant indicators were measured. The patients were divided into different groups according to urinary pH. Clinical characteristics and factors related to urinary pH were compared among the groups. SPSS 23.0 software was used.Results:A total of 2 553 patients were enrolled. There were significant statistical differences in age, body mass index, triglyceride, alanine aminotransferase(ALT), blood urea nitrogen, serum creatinine, estimated glomerular filtration rate(eGFR), blood uric acid, urinary uric acid/creatinine ratio, fraction excretion of uric acid(FEUA) among groups with different urinary pH( F were 5.114, 4.772, 7.170, 4.721, 13.603, 2.812, 3.422, 22.834, 18.230, 26.332, all P<0.05). Urinary uric acid and FEUA in acute group were higher than those in remission group( Z were -2.295, -3.528, both P<0.05). After adjusting for gender, age, eGFR, logistics regression analysis showed that body mass index, triglyceride, total cholesterol, ALT, blood uric acid, and blood urea nitrogen were still risk factors. Multivariate logistic regression analysis showed that triglyceride, blood uric acid, and blood urea nitrogen were independent risk factors associated with acid urine. Linear correlation analysis showed that urinary pH was negatively correlated with body mass index, triglyceride, total cholesterol, blood uric acid, fasting glucose, blood urea nitrogen, ALT( r were -0.079, -0.106, -0.051, -0.186, -0.040, -0.122, -0.051, all P<0.05), but positively correlated with eGFR( r=0.058, P=0.003). Conclusion:The overall urine pH levels in patients with primary gout are below normal reference. Several metabolic components are related to it. Triglyceride, blood uric acid, and blood urea nitrogen are independent risk factors of acidic urine. In clinical practice, attention should be paid to timely alkalization of urine to prevent complications.

Objective:To evaluate the impact of cold-air anesthesia on patients′ comfort and side effects during ablative fractional carbon-dioxide (CO 2) laser treatment for acnescars. Methods:Eighteen patients with atrophic acne scars treated with CO 2 laser were used as split-face comparative study with a cold-air device combined with 5% lidocaine cream on the left side of the face, and the right side as a control group treated with 5% lidocaine cream only. Symptoms and signs of patients were observed during treatment, immediately after treatment, 15 minutes, 30 minutes and 1 month after treatment. The score of patient′s comfort and incidence of adverse events was evaluated. Results:The results were obvious difference between each group. The surface temperature in combined group (33.1±1.3) showed significantly better results compared with other groups (36.9±0.4) during the operative period while the same result after the treatment immediately shown in the combined group (35.1±1.3) compared with other groups (36.4±0.2). The score of erythema shown that combined group (48.7±8.4) was significantly lower than that of the control group (54.8±8.0) ( P<0.05) as the score of exudation in combined group (6.2±1.6) was lower than that in the control group (7.8±1.6). There was significant statistical difference regarding scores of erythema between combined group (46.9±6.6) and control group (51.8±6.9) a month after the treatment. The pigmentation score revealed the same result that the combined group (48.9±8.8) was lower than the other groups (51.4±7.0). No patients had severe adverse events. Conclusions:The cold-air cooling application is safe and effective to reduce the surface temperature, pain and side effects during fractional carbon-dioxide laser treatment.

Objective:To investigate the relationship between intra-abdominal pressure (IAP) and respiratory function in mechanically ventilated children with severe pneumonia and its prognostic value.Methods:A case-series study.Ninety-two children with severe pneumonia who were treated with mechanical ventilation in the Intensive Care Unit of Children′s Hospital Affiliated to Zhengzhou University from May 2019 to May 2021 were taken as the study subjects.The IAP and respiratory function-related indexes of the children were monitored.Those with IAP ≥12 mmHg(1 mmHg=0.133 kPa) were divided into the study group, and those with IAP <12 mmHg were divided into the control group.The difference in respiratory function related indexes between the 2 groups was compared, and the relationship between IAP and respiratory function indexes was analyzed by Pearson correlation.The children were divided into a good prognosis group and a poor prognosis group according to their prognosis.The relevant clinical data of the children in the 2 groups were collected for univariate analysis, and multivariate Logistic regression was used to analyze the risk factors affecting the prognosis of children with mechanical ventilation for severe pneumonia.A receiver operating characteristic (ROC) curve was drawn to analyze the predictive value of IAP on the prognosis of mechanically ventilated children with severe pneumonia.Results:The arterial partial pressure of oxygen (PaO 2) [(80.15±8.23) mmHg], arterial blood oxygen saturation (SaO 2) [(91.32±2.13)%], and oxygenation index (PaO 2/FiO 2) [(198.29±20.25) mmHg] in the study group were lower than those in the control group [(85.74±8.42) mmHg, (97.05±2.47)%, and (234.84±25.24) mmHg], while the respiratory rate (RR) [(56.23±2.16) breaths/min vs. (50.41±2.24) breaths/min], partial pressure of carbon dioxide (PaCO 2) [(36.48±3.72) mmHg vs.(33.29±3.46) mmHg], fraction of inspired oxygen (FiO 2) [(40.42±4.25)% vs.(36.51±3.72)%], mean arterial pressure (MAP) [(55.98±5.69) mmHg vs.(52.79±5.43) mmHg], and positive end expiratory pressure (PEEP) [(5.03±0.52) cmH 2O vs.(4.52±0.47) cmH 2O, 1 cmH 2O=0.098 kPa] were higher than those in the control group, and the differences were all statistically significant (all P<0.05).The IAP of the children in the study group was (14.25±1.83) mmHg, and that in the control group was (10.38±1.14) mmHg.Pearson correlation analysis showed that IAP was negatively correlated with PaO 2, SaO 2, and PaO 2/FiO 2 ( r=-0.615, -0.587, and -0.647, all P<0.05), and was positively correlated with RR, PaCO 2, FiO 2, MAP, and PEEP ( r=0.618, 0.634, 0.579, 0.578, 0.593, all P<0.05).IAP [(14.76±1.58) mmHg], PaCO 2 [(39.95±4.21) mmHg], FiO 2 [(50.29±5.12)%], alanine aminotransferase[(42.08±4.15) U/L], and total bilirubin [(17.92±1.87) μmol/L] in the poor prognosis group were greater than those [(10.75±1.19) mmHg, (35.37±3.64) mmHg, (45.38±4.47)%, (39.87±4.06) U/L, and (17.09±1.75) μmol/L] in the good prognosis group, while PaO 2 [(65.42±7.86) mmHg vs.(76.42±7.51) mmHg], SaO 2 [(90.65±9.26)% vs.(96.21±2.19)%], and PaO 2/FiO 2 [(130.09±15.15) mmHg vs.(168.40±20.17) mmHg] were smaller than those in the good prognosis group, and the differences were statistically significant (all P<0.05).Logistic regression analysis showed that IAP, PaO 2, PaCO 2, and SaO 2 were risk factors affecting the prognosis of mechanically ventilated children with severe pneumonia (all P<0.05).The optimal cut-off point of IAP for predicting a poor prognosis in mechanically ventilated children with severe pneumonia was 14.55 mmHg, and the area under the ROC curve was 0.873, with a sensitivity of 88.10% and a specificity of 76.00%. Conclusions:IAP has a certain relationship with the respiratory function of mechanically ventilated children with severe pneumonia, and has a good predictive value for the prognosis of the children.

Objective To investigate the influencing factors of Mismatch ratio in computed tomography perfusion(CTP)and dif-fusion weighted imaging(DWI)to assess the lesion outcome after treatment in patients with acute ischemic stroke(AIS).Methods Whether there were any differences in clinical and imaging data of AIS patients were analyzed retrospectively between the Mismatch ratio＞1.2 group and the Mismatch ratio≤1.2 group,and between the hemorrhagic transformation group and the non-hemorrhagic transformation group.Results The age of onset and National Institutes of Health Stroke Scale(NIHSS)score of AIS patients in the group with Mismatch ratio＞1.2 were greater than those in the group with Mismatch ratio≤1.2.The Mismatch ratio＞1.2 group had lower incidence of hyperlipidemia,new infarct foci,and higher hypercoagulability,cerebral hemorrhage,as well as large cerebral infarction.The NIHSS score was higher in the hemorrhagic transformation group than the non-hemorrhagic transformation group,and the incidence of large cerebral infarction and digital subtraction angiography(DSA)thrombectomy was higher in the former than in the latter.Multifactorial logistic analysis showed that age,NIHSS score,and hyperlipidemia were independent risk factors for AIS patients with Mismatch ratio＞1.2 and large cerebral infarction was an independent risk factor for hemorrhagic transformation.Conclusion The Mismatch ratio in CTP is correlated with age,NIHSS score,and hyperlipidemia in patients with AIS and large cerebral infarction is correlated with hemorrhagic transformation.
