Objective:To investigate the clinical efficacy of minimally invasive percutaneous internal fixation with double screws for delayed union or nonunion of scaphoid fracture.Methods:A retrospective study was conducted to analyze the 12 patients with delayed union or nonunion of scaphoid fracture who had been treated at Department of Hand and Foot Surgery, The Affiliated Hospital of Jining Medical University from March 2021 to December 2023. They were 11 males and 1 female, with an age of (29.9±13.8) years and an interval from injury to surgery of (5.1±2.6) months. They were all treated by minimally invasive percutaneous internal fixation with 2 hollow compression screws. The visual analogue scale (VAS), grip strength (percentage of the affected side to the healthy side), wrist range of motion, modified Mayo wrist score and other data were recorded and compared between pre-surgery and the last follow-up. The incidence of complications was recorded.Results:Follow-up for all patients lasted for (20.8±8.9) months. All patients achieved bony union after (10.1±3.2) weeks with no complications like infection. No post-surgery imaging revealed screw misplacement or penetration. At the last follow-up, the VAS pain score was 0 (0, 1) point, the wrist grip strength 100.6%±7.2%, the wrist flexion 88.3°±2.5°, the wrist dorsiflexion 88.5°±2.2°, and the modified Mayo wrist score (98.3±2.5) points, all significantly better than the pre-surgery values [4 (4, 5) points, 69.1%±16.0%, 61.3°±13.5°, 64.7°±9.1°, and (61.7±10.1) points] (all P < 0.05). Conclusion:In the treatment of delayed union or nonunion of scaphoid fracture, minimally invasive percutaneous internal fixation with double screws shows advantages of minimal invasion, quick fracture healing, fine functional recovery, and no need of bone grafting.

Turning to critical illness is a common stage of various diseases and injuries before death. Patients usually have complex health conditions, while the treatment process involves a wide range of content, along with high requirements for doctor′s professionalism and multi-specialty teamwork, as well as a great demand for time-sensitive treatments. However, this is not matched with critical care professionals and the current state of medical care in China. Telemedicine, which shortens the distance of medical professionals and the gap of disease diagnosis and treatments in various regions through electronic information, can effectively solve the current problem. Therefore, there is an urgent need to develop a standardized, high-quality visualization telemedicine round system .Therefore, experts have been organized to search domestic and foreign literature on telemedicine round for critically ill patients and to form this consensus based on clinical experiences so as to further improve the level of critical care treatments in regions.

Objective:To investigate the safety and efficacy of balloon pulmonary angioplasty (BPA) for residual pulmonary hypertension (PH) of chronic thromboembolic pulmonary hypertension(CTEPH) after pulmonary endarterectomy (PEA).Methods:Patients diagnosed as PH after PEA in China-Japan Friendship Hospital from Oct 2016 to Jun 2022 were included. The indication for BPA was decided on the basis of a consensus of the multi-disciplinary team for all patients with CTEPH. Before treatment, the patient′s exercise tolerance and pulmonary artery flow parameters were evaluated. A comparative analysis of various parameters before BPA treatment and at the last BPA was conducted. 6-min walk distance (6MWD) was analyzed using the paired Wilcoxon test; N-terminal pro-brain natriuretic peptide (NT-proBNP), mixed venous oxygen saturation, mean pulmonary arterial pressure (mPAP), cardiac index (CI) and pulmonary vascular resistance (PVR) were compared using the paired-samples t-test. WHO functional class was compared using McNemar′s test. Results:Twenty patients with a total of 130 vessels underwent 46 sessions of BPA treatment. The postoperative 6-minute walk distance (6MWD) [447 (415, 485) m] showed a significant improvement compared to the preoperative baseline [389 (335, 470) m] ( Z=6.52, P<0.05), Postoperative mixed venous oxygen saturation (72.0%±1.9%) showed a significant improvement compared to the preoperative levels (64.0%±2.7%) ( t=2.14, P<0.05).Postoperatively, plasma NT-proBNP [(351.9±129.9) pg/ml], mPAP [(24.2±1.9) mmHg], and PVR [(3.0±1.4) WU] significantly decreased compared to preoperative levels [(982.5±426.2) pg/ml, (33±2.1) mmHg, (8.0±1.6) WU)] ( t=3.38, 1.22, 2.10, P<0.05 for all). Postoperatively, there was a significant improvement in WHO functional class (Ⅰ，Ⅱ，Ⅲ，Ⅳ: 14, 4, 2, 0 cases) compared to preoperative status (Ⅰ，Ⅱ，Ⅲ，Ⅳ: 0, 13, 5, 2 cases) ( χ2=20.17, P<0.05). Four cases of pulmonary artery dissection and one episode of hemoptysis occurred postoperatively, with no other complications reported. Conclusions:BPA can significantly improve exercise tolerance and hemodynamic parameters for residual PH after PEA. BPA is a relatively safe and effective treatment for residual PH after PEA.

Objective:To understand the epidemiological characteristics of human respiratory syncytial virus (HRSV) among acute respiratory infection (ARI) cases in 16 provinces of China from 2009 to 2023.Methods:The data of this study were collected from the ARI surveillance data from 16 provinces in China from 2009 to 2023, with a total of 28 278 ARI cases included in the study. The clinical specimens from ARI cases were screened for HRSV nucleic acid from 2009 to 2023, and differences in virus detection rates among cases of different age groups, regions, and months were analyzed.Results:A total of 28 278 ARI cases were enrolled from January 2009 to September 2023. The age of the cases ranged from<1 month to 112 years, and the age M ( Q1, Q3) was 3 years (1 year, 9 years). Among them, 3 062 cases were positive for HRSV nucleic acid, with a total detection rate of 10.83%. From 2009 to 2019, the detection rate of HRSV was 9.33%, and the virus was mainly prevalent in winter and spring. During the Corona Virus Disease 2019 (COVID-19) pandemic, the detection rate of HRSV fluctuated between 6.32% and 18.67%. There was no traditional winter epidemic peak of HRSV from the end of 2022 to the beginning of 2023, and an anti-seasonal epidemic of HRSV occurred from April to May 2023. About 87.95% (2 693/3 062) of positive cases were children under 5 years old, and the difference in the detection rate of HRSV among different age groups was statistically significant ( P<0.001), showing a decreasing trend of HRSV detection rate with the increase of age ( P<0.001). Among them, the HRSV detection rate (25.69%) was highest in children under 6 months. Compared with 2009-2019, the ranking of HRSV detection rates in different age groups changed from high to low between 2020 and 2023, with the age M (Q1, Q3) of HRSV positive cases increasing from 1 year (6 months, 3 years) to 2 years (11 months, 3 years). Conclusion:Through 15 years of continuous HRSV surveillance analysis, children under 5 years old, especially infants under 6 months old, are the main high-risk population for HRSV infection. During the COVID-19 pandemic, the prevalence and patterns of HRSV in China have changed.

Objective:To investigate the clinical characteristics of circadian rhythm disorder of blood pressure and its impact on orthostatic hypotension (OH) in Parkinson′s disease (PD).Methods:A total of 165 PD patients from Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from August 2019 to October 2021 were consecutively enrolled. Medical history and scores of motor and non-motor symptoms of patients were collected. Twenty-four-hour ambulatory blood pressure and OH data were collected, and the OH questionnaire was completed. The incidence of each type of circadian rhythm disorder of blood pressure was investigated. The t test, chi-square test and Mann-Whitney U test were used to determine between-group differences of circadian rhythm disorder of blood pressure. The linear trends in clinical characteristics were tested by linear regression analysis. Logistic regression analysis was used to analyze the relationship between different circadian rhythm disorders of blood pressure and OH as well as symptomatic OH (SOH). Results:In 165 PD patients, the incidence of reverse dipping pattern was 39.39% (65/165), nocturnal hypertension was 43.64% (72/165), and awakening hypotension was 31.52% (52/165). Compared with patients without reverse dipping pattern, patients with reverse dipping pattern were older [(71.72±7.81) years vs (65.29±9.68) years, t=-4.491, P<0.001], had later onset age [(66.67±9.10) years vs (62.16±10.66) years, t=-2.809, P=0.006], longer duration [36.00(20.50, 95.50) months vs 24.00(12.00, 41.75) months, Z=-3.393, P<0.001], higher dose of levodopa (LD) [(426.15±267.38) mg/d vs (284.00±235.58) mg/d, t=-3.590, P<0.001], higher levodopa equivalent dose (LED) [(514.80±360.03) mg/d vs (341.44±284.57) mg/d, t=-3.440, P=0.001], higher Unified Parkinson′s Disease Rating Scale (UPDRS)-Ⅱ scores (12.92±6.38 vs 9.54±5.59, t=-3.434, P=0.001), higher UPDRS-Ⅲ scores (28.34±11.60 vs 21.41±12.18, t=-3.508, P=0.001) and higher percentages of hallucinations [18.46% (12/65) vs 7.00% (7/100), χ2 =5.079, P=0.024]. Compared with patients without awakening hypotension, patients with awakening hypotension were older [(70.83±7.09) years vs (66.44±10.16) years, t=-2.811, P=0.006]. Compared with patients without nocturnal hypertension, patients with nocturnal hypertension had longer duration [39.50(15.00, 96.00) months vs 24.00 (12.00, 36.00) months, Z=-2.944, P=0.003], higher LD [(398.61±251.19) mg/d vs (294.62±254.25) mg/d, t=-2.619, P=0.010], higher LED [(493.28±344.02) mg/d vs (345.05±298.59) mg/d, t=-2.959, P=0.004], higher percentages of hallucinations [19.44% (14/72) vs 5.38% (5/93), χ2 =7.882, P=0.005], higher UPDRS-Ⅱ scores (12.08±6.33 vs 10.00±5.86, t=-2.086, P=0.039), higher UPDRS-Ⅲ scores (26.50±11.72 vs 22.42±12.66, t=-2.034, P=0.044), and greater blood pressure variability (BPV) (20.66±5.47 vs 17.44±5.36, t=-3.798, P<0.001). Trend analysis showed that the variety of circadian rhythm was positively correlated with age and duration, use of levodopa and monoamine oxidase B inhibitors and amantidine, morning and daily LD and LED, UPDRS-Ⅱ, UPDRS-Ⅲ and Hamilton Anxiety Scale scores, hallucinations, OH and SOH, and BPV in PD ( P<0.05). Multivariate Logistic regression analysis showed that awakening hypotension ( OR=3.35, 95% CI 1.55-7.22, P=0.002) and nocturnal hypertension ( OR=2.44, 95% CI 1.20-4.97, P=0.014) were risk factors for OH, and LED ( OR=1.21, 95% CI 1.01-1.43, P=0.035), UPDRS-Ⅲ scores ( OR=1.09, 95% CI 1.02-1.16, P=0.009) and w-BPV ( OR=1.14, 95% CI 1.01-1.29, P=0.029) were independent risk factors for SOH. Conclusions:Circadian rhythm disorder of blood pressure was correlated with age, duration, severity of motor symptoms. Awakening hypotension and nocturnal hypertension are independent risk factors for OH in PD.

Objective To investigate the expression of pseudokinase Tribbles homology 3(TRIB3)and its clinical prognostic value in Siewert type Ⅱ adenocarcinoma of esophagogastric junction(AEG).Methods Western blot and immunohistochemical method were used to detect the expression of TRIB3 in R0 resected Siewert type Ⅱ AEG and its corresponding adjacent tissues,and analyze its rela-tionship with clinical parameters,survival and prognosis.Results Western blot analysis showed that the expression level of TRIB3 in Siewert type Ⅱ AEG tissues was significantly lower than that in the adjacent tissues(P<0.05).The immunohistochemical Results showed that the positive expression rate of TRIB3 in cancer tissues was significantly lower than that in adjacent tissues(P<0.01).The expression of TRIB3 was significantly correlated with the degree of differentiation,clinical TNM stage and lymph node metastasis(P<0.05),but not with age,gender and pathological morphology(P>0.05).Kaplan-Meier survival analysis showed that the long-term survival of patients with positive TRIB3 expression was significantly better than that of patients with negative TRIB3 expression(P<0.01).Univariate(HR =0.290,95%CI:0.110-0.761,P =0.012)and multivariate(HR =0.179,95%CI:0.051-0.630,P = 0.007)COX regression analysis showed that TRIB3 could be used as an independent prognostic factor for patients with Siewert type ⅡAEG(P<0.05).Conclusion TRIB3 may be involved in the occurrence and development of Siewert typeⅡ AEG.It is expected to be-come a new target for early diagnosis and treatment of AEG,and can be used as an important indicator for judging the prognosis of patients.
