OBJECTIVES: To explore the relationship between white matter injury (WMI) and cerebral perfusion in preterm infants using arterial spin labeling (ASL). METHODS: A total of 293 preterm infants (gestational age <34 weeks) hospitalized at the Third Affiliated Hospital of Zhengzhou University between June 2022 and June 2024 were included. After achieving clinical stability, the infants underwent brain magnetic resonance imaging (MRI) and ASL. Based on MRI findings, infants were classified into WMI (n=66) and non-WMI (n=227) groups. Cerebral perfusion parameters were compared between groups, and the association between WMI and perfusion alterations was evaluated. RESULTS: The WMI group showed a higher incidence of mild intraventricular hemorrhage (IVH) than the non-WMI group (P<0.05). Significantly lower cerebral perfusion was observed in the WMI group across bilateral frontal, temporal, parietal, and occipital lobes, as well as the basal ganglia and thalamus (P<0.05). After adjusting for gestational age, corrected gestational age at ASL scan, and mild IVH, WMI remained significantly associated with reduced regional perfusion (P<0.05). CONCLUSIONS WMI in preterm infants correlates with localized cerebral hypoperfusion. ASL-detected perfusion abnormalities may provide novel insights into WMI pathogenesis.

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 In this preliminary survey,we sought to determine the composition of mosquito species inhabiting the Emeifeng Nature Reserve,Fujian Province,China.Methods Mosquito larvae were collected by straw and spoon trapping,and adult mosquitoes were collected by lamp trapping at selected breeding sites in the reserve.The specimens were initially identified based on morphology,with subsequent verification using molecular biology methods.Results A total of 34 mosquito species in 13 genera were collected,among which,there were 4 species of Anopheles(Genus Anopheles Meigen,1818),2 species of Lutzia(Genus Lutzia Theobald,1903),15 species of Culex(Genus Culex Linnaeus,1758),4 species of Stegomyia(Genus Stegomyia Theobald,1901),and single species of Hulecoeteomyia(Genus Hulecoeteomyia Theobald,1904),Luius(Genus Luius Reinert,Harbach et Kitching,2008),Aedes(Genus Aedes Meigen,1818),Downsiomyia(Genus Downsiomyia Vargas,1950),Collessius(Genus Collessius Reinert,Harbach et kitching,2006),Uranotaenia(Genus Uranotaenia Lynch 1891),Armigeres(Genus Armigeres Theobald,1901),Toxorhynchites(Genus Toxorhynchites Theobald,1901),and pestle mosquito(Genus Tripteroides Giles,1904).Conclusions The species composition of mosquitoes sampled in the Emeifeng Nature Reserve will provide a basis for further research on mosquito vectors and contribute to measures for local mosquito control.

Objective:To evaluate the curative effects of 3D printed microporous titanium (tantalum) prosthesis in reconstruction of large segmental bone defects caused by lower extremity osteomyelitis.Methods:A retrospective study was conducted to analyze the clinical data of 18 patients who had been treated for large segmental bone defects caused by lower extremity osteomyelitis between January 2020 to May 2022 at Department of Orthopaedics, The 920th Hospital of Joint Logistics Support Force. There were 10 males and 8 females with an age of (45.3±14.1) years. The defects were at the left side in 13 cases and at the right side in 5 cases, at the femur in 11 cases and at the tibia in 7 cases. The duration of osteomyelitis was 1.0 (1.0, 3.5) years. The length of bone defects was 8.35 (6.50, 9.84) cm. Their bone defects were repaired by an individually 3D printed microporous titanium (tantalum) prosthesis after operative removal of osteomyelitis lesions. The wound healing was observed after surgery. The clinical efficacy was comprehensively evaluated by the Paley grading for bone defect healing, visual analog scale (VAS), lower extremity functional scale (LEFS), and imaging examination.Results:The postoperative follow-up period for the 18 patients was (12.2±0.3) months. Wound infection occurred 2 months after surgery in one patient who was treated with Ilizarov bone transfer after removal of the microporous titanium prosthesis. The remaining 17 patients had good postoperative wound healing. At the last follow-up, the 18 patients had a VAS pain score of 2.0(1.0, 4.0) points, significantly lower than the preoperative one [(6.1±2.3) points], and a LEFS score of 54.00(34.50, 69.25) points, significantly higher than the preoperative one [18.50(9.00, 26.50) points] ( P<0.05). At the last follow-up, according to the Paley grading, the bone union was rated as excellent in 16 patients, as good in 1 patient and as poor in 1 patient. The integration of femoral fractures with 3D printed microporous titanium prostheses was fine. Conclusion:In reconstruction of large segmental bone defects caused by lower extremity osteomyelitis, implantation of a 3D printed microporous titanium (tantalum) prosthesis is feasible and effective, not only reducing pain but also restoring the limb function.

Silver nanoparticles(AgNPs)is widely used in biomedicine,daily chemicals,food industry and other fields,and the possible negative health effects of its exposure have attracted widespread attention.Accurate analysis of AgNPs in biological matrices is the basis for biosafety studies of AgNPs.Among the existing analytical techniques,single particle-inductively coupled plasma-mass spectrometry(sp-ICP-MS)has significant advantages such as high sensitivity and simultaneous detection of different forms of silver.However,AgNPs in biological matrices is uniquely highly dynamic and low in content,and the matrix interference is severe,which increases the complexity of the analysis.Although some scholars have reviewed the application of this method for detection of metal nanoparticles in different scenarios,there is a lack of a summary of the quality control and optimization of the whole process from the perspective of AgNPs detection.There is still a lack of reference standards for the sp-ICP-MS analysis of AgNPs in biological matrices,and the existing methods need to be summarized and further optimized to achieve accurate quantification.Therefore,this paper reviewed the recent studies on the analysis of silver-containing nanoparticles in biological matrices based on sp-ICP-MS,mainly included the principles of the technique,the extraction methods of the particles,and the process of data processing,which focused on elaborating and comparing different pre-treatment methods,and explored issues of the current application of sp-ICP-MS for detection of AgNPs in biological tissues and the development of future optimization trends.The current problems of sp-ICP-MS for detection of AgNPs in biological tissues and the future development trend were also discussed.

Objective:To investigate the efficiency and safety of the pulsatile GnRH therapy in the treatment of male congeni-tal hypogonadotropic hypogonadism(CHH).Methods:We retrospectively analyzed the clinical data on 45 CHH males treated by pulsatile GnRH therapy in our hospital from January 2013 to March 2023.We treated the patients with gonadorelin at 7-15 μg,one pulse/90 min,and followed them up every month in the first 3 months and then every 3 to 6 months after treatment,for an average of 19.1±4.3 months,during which we recorded the height,body weight,penile length,testis volume,Tanner stages,levels of FSH,LH and T,semen parameters and adverse reactions of the patients,followed by comparison of the data obtained with the baseline.Results:The levels of FSH,LH and T of the patients were dramatically elevated after treatment(P<0.01).The T level of the6 ca-ses of cryptorchidism,however,failed to reach the normal value within 18.2±8.6 months of follow-up.Significant improvement was seen in the external genitalia and secondary sexual characteristics of all the patients,and spermatogenesis was observed in the semen in 33 cases(73.3% ),with a mean sperm concentration of(18.2±6.2)106/ml,sperm progressive motility of(19.7±6.5)%,and semen volume of(1.8±0.6)ml.Eight of the cases achieved natural fertility,and another 3 achieved childbirth by assisted re-productive technology.As for adverse events,gynecomastia was observed in 8,subcutaneous induration in 6,and allergic reaction to therapeutic agent in 3 cases.Conclusion:Pulsatile GnRH therapy is an effective and safe strategy for male CHH.However,clini-cians should choose appropriate approaches to different individual cases.

During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.
