Insulin-like growth factor 2 (IGF2) is a critical endocrine mediator implicated in male reproductive physiology. To investigate the correlation between IGF2 protein levels and various aspects of male infertility, specifically focusing on sperm quality, inflammation, and DNA damage, a cohort of 320 male participants was recruited from the Women's Hospital, Zhejiang University School of Medicine (Hangzhou, China) between 1 st January 2024 and 1 st March 2024. The relationship between IGF2 protein concentrations and sperm parameters was assessed, and Spearman correlation and linear regression analysis were employed to evaluate the independent associations between IGF2 protein levels and risk factors for infertility. Enzyme-linked immunosorbent assay (ELISA) was used to measure IGF2 protein levels in seminal plasma, alongside markers of inflammation (tumor necrosis factor-alpha [TNF-α] and interleukin-1β [IL-1β]). The relationship between seminal plasma IGF2 protein levels and DNA damage marker phosphorylated histone H2AX (γ-H2AX) was also explored. Our findings reveal that IGF2 protein expression decreased notably in patients with asthenospermia and teratospermia. Correlation analysis revealed nuanced associations between IGF2 protein levels and specific sperm parameters, and low IGF2 protein concentrations correlated with increased inflammation and DNA damage in sperm. The observed correlations between IGF2 protein levels and specific sperm parameters, along with its connection to inflammation and DNA damage, underscore the importance of IGF2 in the broader context of male reproductive health. These findings lay the groundwork for future research and potential therapeutic interventions targeting IGF2-related pathways to enhance male fertility.

Deficiencies in the clearance of peripheral amyloid β (Aβ) play a crucial role in the progression of Alzheimer's disease (AD). Previous studies have shown that the ability of blood monocytes to phagocytose Aβ is decreased in AD. However, the exact mechanism of Aβ clearance dysfunction in AD monocytes remains unclear. In the present study, we found that blood monocytes in AD mice exhibited decreases in energy metabolism, which was accompanied by cellular senescence, a senescence-associated secretory phenotype, and dysfunctional phagocytosis of Aβ. Improving energy metabolism rejuvenated monocytes and enhanced their ability to phagocytose Aβ in vivo and in vitro. Moreover, enhancing blood monocyte Aβ phagocytosis by improving energy metabolism alleviated brain Aβ deposition and neuroinflammation and eventually improved cognitive function in AD mice. This study reveals a new mechanism of impaired Aβ phagocytosis in monocytes and provides evidence that restoring their energy metabolism may be a novel therapeutic strategy for AD.

To systemically evaluate the effect of Qishen Yiqi Dripping Pills combined with Western medicine on adverse cardiovascular events and quality of life after percutaneous coronary intervention(PCI). A total of 7 Chinese and English databases including CNKI, Wanfang, VIP, SinoMed, PubMed, Cochrane Library and Web of Science were searched by computer to collect the randomized controlled trials(RCTs) on Qishen Yiqi Dripping Pills combined with Western medicine in the treatment of patients with coronary heart disease after PCI with the retrieval time from the database establishment to April 1, 2020. Two researchers independently conducted li-terature screening, data extraction and bias risk assessment. Then, Meta-analysis was performed by using RevMan 5.3 software. A total of 31 RCTs were included, involving 3 537 patients. The results of Meta-analysis showed that in terms of major adverse cardiovascular events(MACE) after PCI, the combination of Qishen Yiqi Dripping Pills could significantly reduce the recurrence of angina pectoris, incidence of arrhythmia, heart failure and re-revascularization, and the effect was better than that of Western medicine treatment alone. However, there was no significant difference between the two groups in the improvement of non-fatal myocardial infarction, cardiac death, stent restenosis, stroke and other adverse cardiovascular events. In terms of improving left ventricular ejection fraction(LVEF), 6 min walking test(6 MWT), high-sensitivity C-reactive protein(hs-CRP) and Seattle angina pectoris scale(SAQ), the combination of Qishen Yiqi Dripping Pills and Western medicine treatment had obvious advantages over Western medicine treatment alone in increasing LVEF, 6 MWT and SAQ, and reducing the level of hs-CRP, with statistically significant differences. There were few adverse reactions in both groups, and there was no significant difference between the two groups. The main manifestations were gastrointestinal reactions, rash, gingiva and other small bleeding, and no serious adverse reactions occurred. The above reactions could disappear after drug withdrawal or symptomatic treatment. The application of Qishen Yiqi Dripping Pills combined with Western medicine in the treatment of patients after PCI could reduce the occurrence of MACE, improve the clinical efficacy, quality of life and prognosis in a safe and reliable manner. However, due to the quantity and quality limitations of included studies, more standardized, rigo-rous and high-quality clinical studies are still needed to further verify the above conclusions.

With continuous discovery of tumor immune targets and continuous changes in antibody research and development technology, antibody drugs are becoming more and more widely used in clinical practice. However, some targets are not only expressed on tumor cells, but also on red blood cells. Therefore, the clinical application of antibodies against the corresponding targets may interfere with the detection of blood transfusion compatibility, resulting in difficulty in blood matching or delay of blood transfusion. This consensus summarizes the current solutions for the interference of CD38 monoclonal antibody (CD38 mAb) in transfusion compatibility testing. After analyzing the advantages and disadvantages of different methods, polybrene and sulfhydryl reducing agents [dithiothreitol (DTT) or 2-mercaptoethanol (2-Me)], as a solution for CD38 mAb interference in blood compatibility testing, are recommended for Chinese patients, so as to eliminate blood transfusion interference produce by CD38 mAb and further provide a pre-transfusion workflow for clinicians and technicians in Department of Blood Transfusion.

To preliminarily analyze the prevention and control of COVID-19, a general hospital outpatient service took six management measures, including setting up a leading group, building rules and regulations, infection control and supervision, special training, humanized service, public opinion propaganda. After nearly two months, the rates of both body temperature monitoring and epidemiological history screening are 100%, the medical staff infection rate is zero, and no cross infection between the patients due to adopting outpatient service comprehensive management measures which had strong organization and leadership, effective targeted training, effective control of all links in epidemic prevention and control work. During the fight against COVID-19, outpatient management played an important role in hospital management. The above approaches provide valuable experience for preventing the spread of infectious diseases effectively and winning the biological weapon wars in the future.

Large general hospitals currently play an increasingly important role in the diagnosis and treatment for acute critical patients and difficult diseases because of the development of dual referral system and hierarchical diagnosis, as well as the formation of medical treatment alliance. Patients with oral cancers are often associated with systemic diseases, which increases the complexity of the condition. Thus, meeting the demand through the traditional single medical model is difficult. As such, a multidisciplinary team (MDT) model has been proposed and has achieved a good clinical effect. To standardize the application of this model, we organized an event in which relevant experts discussed and formulated a consensus to provide standardized suggestions on the MDT process and the diagnosis and treatment of common systemic diseases as reference for clinical practice.

Objective:
To compare the results obtained from the computer-aided sperm analysis (CASA) systems of the two fully-automated commercial sperm quality analyzers, Hamilton-Thorn IVOS Ⅱ (IVOS Ⅱ) and Spanish Sperm Class Analyzer (SCA).
METHODS:
A total of 99 semen samples were collected in the Center of Reproduction of Shenzhen Zhongshan Urology Hospital from September 2018 to October 2018 and, according to the sperm concentration, divided into groups A (<15 ×10⁶/ml), B (15-50 ×10⁶/ml) and C (>50 ×10⁶/ml). IVOS Ⅱ, SCA and manual microscopy were used for the examination of each sample, followed by comparison of the sperm concentration, sperm motility and percentage of progressively motile sperm (PMS) obtained from IVOS Ⅱ and SCA.
RESULTS:
The sperm concentrations derived from IVOS Ⅱ and SCA were significantly higher than that from manual microscopy in group A ([10.24 ± 4.60] and [10.20 ± 5.11] vs [8.45 ± 4.15] ×10⁶/ml, P < 0.05), but showed no statistically significant difference in group B ([30.95 ± 11.84] and [31.81 ± 12.90] vs [29.14 ± 10.65] ×10⁶/ml, P > 0.05) or C ([102.14 ± 45.97] and [109.48 ± 46.32] vs [104.74 ± 41.87] ×10⁶/ml, P > 0.05). Significant differences were not observed between IVOS Ⅱ and SCA in the percentage of PMS ([24.21 ± 14.62]% vs [23.92 ± 15.42]%, P > 0.05) or sperm motility ([37.48 ± 19.34]% vs [37.69 ± 16.61]%, P > 0.05) in group B, nor in group C (PMS: [30.80 ± 12.06]% vs [32.98 ± 16.10]%, P > 0.05; sperm motility: [44.50 ± 15.62]% vs [47.26 ± 17.46]%, P > 0.05). Both the percentage of PMS and sperm motility obtained from IVOS Ⅱ were remarkably lower than those derived from SCA in group A (PMS: [18.54 ± 12.96]% vs [22.90 ± 12.88]%, P < 0.05; sperm motility: [26.97 ± 14.05]% vs [34.90 ± 15.18]%, P < 0.05). IVOS Ⅱ and SCA both showed a high repeatability (CV <15%), and the former exhibited an even higher one than the latter, in detection of sperm concentration, sperm motility and the percentage of PMS.
CONCLUSIONS
IVOS Ⅱ and SCA both had a good consistency in the results of sperm concentration, motility and progressive motility, but showed a poor comparability with low-concentration semen samples.

OBJECTIVE:
To explore the application value and clinical effect of three-dimensional printing combined with composite plate internal fixation in the treatment of old acetabular posterior wall fracture.
METHODS:
From May 2010 to October 2016, Mimics 19.0 software was used to plan preoperatively according to a 1:1 print pelvic 3D model. At the same time, 23 patients with old acetabular posterior wall fractures were treated with combined plate internal fixation, including 15 males and 8 females, aged 20 to 63 (43.0±5.1) years old, and the time from injury to operation was 23 to 101(47.0±10.5) days. According to Letournel-Judet classification, 11 cases were posterior wall fracture, 7 cases were transverse with posterior wall fracture, and 5 cases were posterior column with posterior wall fracture. All patients were treated with single Kocher-Langenbeck approach combined plate internal fixation, and the evaluation indexes were recorded during operation, after operation and during follow-up.
RESULTS:
The operation time of 23 patients was (113.5±11.5) min, bleeding was (550.0±104.7) ml and fluoroscopy was (12.7±0.8) s. Matta radiographic reduction criteria were used: excellent in 14 cases, good in 7 cases and poor in 2 cases; 23 patients were followed up for 10 to 24 (16.0±5.6) months. The hip function was evaluated according to the modified Merle d'Aubingne and Postal scoring system at the last follow-up: excellent in 11 cases, good in 8 cases, fair in 3 cases and poor in 1 case. There were 3 cases of traumatic arthritis, 1 case of femoral head necrosis, 2 cases of heterotopic ossification and 5 cases of sciatic nerve irritation.
CONCLUSIONS
3D printing technique is an effective and fast method for the treatment of old acetabular posterior wall fractures. In addition, the printing model can provide three-dimensional morphological structure for the operator, combined with preoperative simulation, facilitate intraoperative reduction, and effectively improve the efficiency of surgery.
