Objective:To investigate the clinical manifestations, therapeutic strategies and prognostic outcomes in pediatric patients with severe Mycoplasma pneumoniae pneumonia (SMPP) complicated by cardiac thrombosis. Methods:This case series study retrospectively analyzed 15 pediatric patients with SMPP complicated by cardiac thrombosis. The patients was recruited from the Department of Pediatric Respiratory Medicine at Shandong Provincial Hospital Affiliated to Shandong First Medical University between July 2018 and January 2025. Comprehensive clinical data and follow-up information were collected.Results:Among the 15 children, 10 were male and 5 were female, and the age of onset was 8.0 (6.3, 10.0) years. All 15 children presented with fever and cough, while additional symptoms included dyspnea in 7 cases, chest pain in 6 cases, hemoptysis in 3 cases, and chest tightness in 1 case. The white blood cell count was 11.7 (9.5, 15.9)×10 9/L, C-reactive protein was 31.6 (17.5, 64.8) mg/L and lactate dehydrogenase was 548.2 (410.4, 768.3) U/L. A total of 14 children underwent testing for the Mycoplasma pneumoniae drug resistance genes 2063A>G and 2064A>G, of which 13 tested positive. The plasma D-dimer levels of 15 children were 8.77 (7.23, 12.50) mg/L, all of which were higher than normal. Among the 15 children, 5 had decreased activity of anticoagulant proteins (protein C, protein S, antithrombin Ⅲ), and 8 tested positive for antiphospholipid antibodies. Chest CT scans of all 15 children showed pulmonary consolidation and (or) atelectasis, with pleural effusion present in 12 cases. In the 15 children, thrombosis was detected at 14.0 (11.0, 18.0) days after the onset of illness. The locations of cardiac thrombosis included the right ventricle in 9 cases, the right atrium in 5 cases, and the left atrium in 1 case. Additionally, 10 cases had pulmonary vascular embolism, comprising 9 cases of pulmonary artery thrombosis and 1 case of pulmonary vein thrombosis. After anticoagulant treatment, cardiac thrombi disappeared in 10 children. Five children who did not show improvement with anticoagulation underwent surgical thrombectomy. In the follow-up of 15 children, lung imaging basically returned to normal, with no major hemorrhagic events or other adverse events. Conclusions:In children with Mycoplasma pneumoniae pneumonia, the presence of clinical symptoms such as shortness of breath, chest pain and hemoptysis, along with elevated plasma D-dimer levels, should raise suspicion for the possibility of cardiac thrombosis. SMPP complicated by cardiac thrombosis, prognosis is good following anticoagulation or surgical treatment.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

The academic thoughts of professor GAO Wei-bin regarding the use of electroacupuncture in the treatment of dry eye are introduced. Professor GAO believes that the occurrence of dry eye is mainly related to the stagnation of qi and blood in the eye meridians, leading to inadequate nourishment of the eyes. The acupuncture treatment principle focuses on promoting blood circulation, clearing and benefiting the eye orifices. By integrating traditional acupuncture theory with modern neuroanatomy, the treatment approach centers on stimulating the lacrimal gland, emphasizing the importance of promoting, addressing symptoms as a priority, and considering both the root cause and symptoms.The precise acupoint selection is emphasized. Acupoints of periocular region, such as Taiyang (EX-HN 5) and Leixian point are selected along with Fengchi (GB 20) and Gongxue point to treat dry eye. Attention is also given to the use of electroacupuncture and the selection of its frequencies, emphasizing specific needling techniques based on the severity and classification of the disease.

OBJECTIVE: To analyze the feasibility of using vascular plaque quantification (VPQ) to evaluate carotid atherosclerotic plaques and to observe the effect of statins on carotid atherosclerotic plaques. METHODS: Patients with carotid plaques from January 2016 to September 2018 in Peking University First Hospital Neurology Department were recruited and underwent three-dimonsional ultrasound (3DUS). Their gray scale median (GSM) and other parameters of carotid plaques were measured with VPQ. The patients were divided into low GSM group (GSM < 40) and high GSM group (GSM≥40). The clinical characteristics and plaque characteristics of the patients in the two groups were compared to analyze the stability of plaques. According to whether taking statins or not, the patients were further divided into statin group and non-statin group, plaque GSM and other parameters of their carotid plaques were measured and the changes of carotid plaques at the end of 3 months and 2 years were observed. RESULTS: A total of 120 patients were enrolled, including 79 males and 41 females, with an average age of (65.39±9.11) years. The patients were divided into low GSM group (31 cases) (GSM < 40) and high GSM group (89 cases) (GSM≥40). The stenosis of the lumen in the low GSM group was more severe (the area stenosis rate was 41.32%±21.37% vs. 29.79%±17.16%, P < 0.05). The nor-malized wall index (NWI) of plaque in low GSM group was significantly higher than that in high GSM group (0.61 ±0.14 vs. 0.52±0.12, P < 0.01). A total of 77 patients, including 51 males and 26 females, aged (64.96±9.58) years, were enrolled to observe the statin effects on carotid plaque. They were divided into statin group (n=56) and non-statin group (n=21) according to whether taking statins or not. At the baseline and 3-month follow-up, there were no significant differences in carotid plaque volume, area, degree of luminal stenosis and GSM between the two groups (P>0.05). At the end of the 2-year follow-up, GSM increased in the statin group [median 10.00 (2.00, 28.00)] but decreased in the non-statin group [median －7.00 (－11.00, 5.50)], with a statistically significant difference between the two groups (P < 0.01). There was no significant increase in carotid plaque volume in the statin group, while there was a slight increase in the non-statin group, but there was no significant difference between the two groups [median increase in plaque volume was 0.00 (－30.00, 40.00) mm³ in the statin group and 30.00 (10.00, 70.00) mm³ in the non-statin group, P>0.05]. CONCLUSION The VPQ technology of 3DUS can be used to evaluate carotid atherosclerotic plaques. Patients with low GSM (GSM < 40) have more severe vascular stenosis and higher normalized wall index. VPQ technology can also be used to observe the effect of statins on carotid plaque, the GSM of plaques increase in patients who are taking moderate-intensity statin treatment for two years.

Objective: To compare clinical efficacy between laparoscopic radical proximal gastrectomy with double-tract reconstruction (LPG-DTR) and laparoscopic radical total gastrectomy with Roux-en-Y reconstruction (LTG-RY) in patients with early upper gastric cancer, and to provide a reference for the selection of surgical methods in early upper gastric cancer. Methods: A retrospective cohort study method was carried out. Clinical data of 80 patients with early upper gastric cancer who underwent LPG-DTR or LTG-RY by the same surgical team at the Department of General Surgery, the First Affiliated Hospital of Xi'an Jiaotong University from January 2018 to January 2021 were retrospectively analyzed. Patients were divided into the DTR group (32 cases) and R-Y group (48 cases) according to surgical procedures and digestive tract reconstruction methods. Surgical and pathological characteristics, postoperative complications (short-term complications within 30 days after surgery and long-term complications after postoperative 30 days), survival time and nutritinal status were compared between the two groups. For nutritional status, reduction rate was used to represent the changes in total protein, albumin, total cholesterol, body mass, hemoglobin and vitamin B12 levels at postoperative 1-year and 2-year. Non-normally distributed continuous data were presented as median (interquartile range), and the Mann-Whitney U test was used for comparison between groups. The χ(2) test or Fisher's exact test was used for comparison of data between groups. The Mann-Whitney U test was used to compare the ranked data between groups. The survival rate was calculated by Kaplan-Meier method categorical, and compared by using the log-rank test. Results: There were no statistically significant differences in baseline data betweeen the two groups, except that patients in the R-Y group were oldere and had larger tumor. Patients of both groups successfully completed the operation without conversion to laparotomy, combined organ resection, or perioperative death. There were no significant differences in the distance from proximal resection margin to superior margin of tumor, postoperative hospital stay, time to flatus and food-taking, hospitalization cost, short- and long-term complications between the two groups (all P>0.05). Compared with the R-Y group, the DTR group had shorter distal margins [(3.2±0.5) cm vs. (11.7±2.0) cm, t=-23.033, P<0.001], longer surgery time [232.5 (63.7) minutes vs. 185.0 (63.0) minutes, Z=-3.238, P=0.001], longer anastomosis time [62.5 (17.5) minutes vs. 40.0 (10.0) minutes, Z=-6.321, P<0.001], less intraoperative blood loss [(138.1±51.6) ml vs. (184.3±62.1) ml, t=-3.477, P=0.001], with significant differences (all P<0.05). The median follow-up of the whole group was 18 months, and the 2-year cancer-specific survival rate was 97.5%, with 100% in the DTR group and 95.8% in the R-Y group (P=0.373). Compared with R-Y group at postoperative 1 year, the reduction rate of weight, hemoglobin and vitamin B12 were lower in DTR group with significant differences (all P<0.05); at postoperative 2-year, the reduction rate of vitamin B12 was still lower with significant differences (P<0.001), but the reduction rates of total protein, albumin, total cholesterol, body weight and hemoglobin were similar between the two groups (all P>0.05). Conclusions: LPG-DTR is safe and feasible in the treatment of early upper gastric cancer. The short-term postoperative nutritional status and long-term vitamin B12 levels of patients undergoing LPG-DTR are superior to those undergoing LTG-RY.

Objective:To investigate the clinical characteristics and etiology of pulmonary embolism in children, and to discuss the efficacy and safety of anticoagulation therapy.Methods:The data of 30 children with pulmonary embolism, who were treated with anticoagulation therapy in the Department of Pediatrics, Provincial Hospital Affiliated to Shandong First Medical University from January 2017 to December 2021, were analyzed retrospectively.The etiology, clinical characteristics, complications, outcomes and prognosis after anticoagulation treatment were analyzed.Results:There were 17 males and 13 females, with an average age of (8.95±2.58) years (age range: 4-13 years). The follow-up duration was 3-59 months.(1) The symptoms included cough in 30 cases (100.0%), fever in 29 cases (96.7%), shortness of breath in 27 cases (90.0%), chest pain in 15 cases (50.0%), hemoptysis in 9 cases (30.0%), bloody secretions under bronchoscopy but no hemoptysis in 4 cases (13.3%), and respiratory failure in 2 cases (6.7%). (2) The protopathy was Mycoplasma pneumoniae infection in 23 cases (76.7%), whose symptoms accorded with refractory Mycoplasma pneumoniae pneumonia.About 16 cases (53.3%) were positive for Mycoplasma pneumoniae drug resistance mutation 2063A>G or 2064A>G.Two cases (6.7%) had nephrotic syndrome.One case (3.3%) had purpura nephritis (nephrotic syndrome type). One case (3.3%) was lupus nephritis (nephrotic syndrome type). One case (3.3%) was hereditary protein S deficiency.One case (3.3%) had osteomyelitis and Staphylococcus aureus sepsis.One case (3.3%) had congenital heart disease.(3) Complications included limb thrombosis in 7 cases (23.3%), atrial thrombosis in 2 cases (6.7%), thoracic and abdominal deep venous thrombosis in 2 case (6.7%), cerebral infarction in 2 cases (6.7%), and splenic infarction in 1 case (3.3%). (4) Imaging examination showed that 30 children had lung consolidation/atelectasis (100.0%), and 24 cases had pleural effusion (80.0%). (5) Coagulation function examination suggested D-dimer increased to ≥ 5 mg/L in 21 cases (70.0%). (6) One case (3.3%) was given thrombolytic therapy with urokinase at the acute stage.Nine cases (30.0%) were treated with heparin/low molecular weight heparin.Twenty-one cases (70.0%) first received anticoagulation therapy with heparin/low molecular weight heparin and later took oral anticoagulant.Four cases (13.3%) were treated with Warfarin and 17 cases (56.7%) with Rivaroxaban.The anticoagulant treatment lasted 1-9 months.No recurrence of embolism or sequelae of chronic thromboembolic pulmonary hypertension was observed. Conclusions:Infection, especially Mycoplasma pneumoniae infection, is the main cause of pulmonary embolism in children.The symptoms of pulmonary embolism in children are atypical, so it is difficult to distinguish this disease from primary underlying diseases.Bronchoscopy can help find occult pulmonary hemorrhage.Unexplained shortness of breath in children of any age suggests the possibility of pulmonary embolism.Combination of clinical symptoms and necessary examination contribute to early diagnosis of pulmonary embolism.Then selection of appropriate anticoagulant drugs and timely anticoagulant therapy can improve the prognosis of children.

BACKGROUND: Coronavirus disease 2019 (COVID-19), which is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has rapidly spread throughout the world. In this study, we aimed to identify the risk factors for severe COVID-19 to improve treatment guidelines. METHODS: A multicenter, cross-sectional study was conducted on 313 patients hospitalized with COVID-19. Patients were classified into two groups based on disease severity (nonsevere and severe) according to initial clinical presentation. Laboratory test results and epidemiological and clinical characteristics were analyzed using descriptive statistics. Univariate and multivariate logistic regression models were used to detect potential risk factors associated with severe COVID-19. RESULTS: A total of 289 patients (197 nonsevere and 92 severe cases) with a median age of 45.0 (33.0, 61.0) years were included in this study, and 53.3% (154/289) were male. Fever (192/286, 67.1%) and cough (170/289, 58.8%) were commonly observed, followed by sore throat (49/289, 17.0%). Multivariate logistic regression analysis suggested that patients who were aged ≥ 65 years (OR: 2.725, 95% confidence interval [CI]: 1.317-5.636; P = 0.007), were male (OR: 1.878, 95% CI: 1.002-3.520, P = 0.049), had comorbid diabetes (OR: 3.314, 95% CI: 1.126-9.758, P = 0.030), cough (OR: 3.427, 95% CI: 1.752-6.706, P < 0.001), and/or diarrhea (OR: 2.629, 95% CI: 1.109-6.231, P = 0.028) on admission had a higher risk of severe disease. Moreover, stratification analysis indicated that male patients with diabetes were more likely to have severe COVID-19 (71.4% vs. 28.6%, χ2 = 8.183, P = 0.004). CONCLUSIONS The clinical characteristics of those with severe and nonsevere COVID-19 were significantly different. The elderly, male patients with COVID-19, diabetes, and presenting with cough and/or diarrhea on admission may require close monitoring to prevent deterioration.

BACKGROUND: The prevalence of skin diseases and diabetes mellitus (DM) are prominent around the world. The current scope of knowledge regarding the prevalence of skin diseases and comorbidities with type 2 DM (T2DM) is limited, leading to limited recognition of the correlations between skin diseases and T2DM. METHODS: We collected 383 subjects from the Da Qing Diabetes Study during the period from July 9th to September 1st, 2016. The subjects were categorized into three groups: Normal glucose tolerance (NGT), impaired glucose tolerance (IGT), and T2DM. The prevalence and clinical characteristics of skin diseases were recorded and investigated. RESULTS: In this cross-sectional study, 383 individuals with ages ranging from 53 to 89-year-old were recruited. The overall prevalence of skin diseases was 93.5%, and 75.7% of individuals had two or more kinds of skin diseases. Additionally, there were 47 kinds of comorbid skin diseases in patients with T2DM, of which eight kinds of skin diseases had a prevalence >10%. The prevalence of skin diseases in NGT, IGT, and T2DM groups were 93.3%, 91.5%, and 96.6%, respectively; stratified analysis by categories showed a statistically significant difference in "disturbances of pigmentation" and "neurological and psychogenic dermatoses". The duration of T2DM also significantly associated with the prevalence of "disturbances of pigmentation" and "neurological and psychogenic dermatoses". Subsequently, the prevalence of "disturbances of pigmentation" was higher in males than females in NGT (P < 0.01) and T2DM (P < 0.01) groups. In addition, the difference in the prevalence of "disturbances of pigmentation" was also significant in NGT and T2DM groups (P < 0.01). CONCLUSIONS There was a high prevalence of skin diseases in the Da Qing Diabetes Study. To address the skin diseases in the Da Qing Diabetes Study, increased awareness and intervention measures should be implemented.
