The clinical data and genetic test results of a 7-year-old female child with cerebral cavernoma were retrospectively analyzed. The child was admitted to the hospital due to a one-month headache. Brain MRI showed cerebral cavernoma. The genetic testing showed a pathogenic heterozygous mutation c.456T＞G (p.Tyr152Ter, 61) in the programmed cell death 10 (PDCD10) gene, while both parents had the wild-type at the locus. The child had no symptoms of epileptic seizures, cerebral hemorrhage, or neurological dysfunction, and received conservative treatment, with regular outpatient follow-up MRI scans.

ObjectiveTo investigate a suspected outbreak of healthcare-associated infection with carbapenem-resistant Klebsiella pneumoniae (CRKP) in a geriatric emergency ward, and to provide references for the prevention and control of multidrug-resistant bacteria in a hospital in Shanghai. MethodsOn-site epidemiological investigation, combined with environmental hygiene monitoring and pulsed field gel electrophoresis (PFGE) molecular typing method, were adopted to investigate a suspected outbreak of CRKP infection in the geriatric emergency ward of a hospital from October to November 2022, aiming at finding out factors caused the outbreak before taking corresponding control measures. ResultsA total of 3 cases of healthcare-associated CRKP infection were identified, of which 2 cases were homologous to a previous case of community-associated CRKP infection. What’s more, the 2 cases lived in the same ward with the latter and with adjacent beds, but the third case was non-homologous to the community-associated infection case. A total of 46 samples were collected from the environmental surfaces and the hands of healthcare workers, of which 7 samples tested positive for CRKP and were identical to the strains from the 2 healthcare-associated infection cases and the 1 community-associated infection case, originating from the bedrails, bedside tables, surface of non-invasive ventilator, bed curtains and panels of monitoring equipment, with a detection rate of 15.22%. But none of the 11 samples from the hands of healthcare workers tested positive for CRKP. The outbreak was effectively controlled after taking specific prevention and control measures such as strengthening personnel management, intensifying environmental cleaning and disinfection and strictly enforcing hand hygiene among healthcare workers. Subsequently, no similar new cases were reported during the 14-day follow-up period. ConclusionIncomplete environmental cleaning and disinfection, as well as inadequate enforcement of hand hygiene among heatheare workers may have contributed to the suspected outbreak of CRKP in the geriatric emergency ward. Early warning and timely investigation of suspected outbreaks of multidrug-resistant bacteria are crucial for preventing and controlling such outbreaks in hospitals.

Transarterial radioembolization (TARE) is a widely utilized therapeutic approach for hepatocellular carcinoma (HCC), however, the clinical implementation is constrained by the stringent preparation conditions of radioembolization agents. Herein, we incorporated the superstable homogeneous iodinated formulation technology (SHIFT), simultaneously utilizing an enhanced solvent form in a carbon dioxide supercritical fluid environment, to encapsulate radionuclides (such as ¹³¹I,¹⁷⁷Lu, or ¹⁸F) with lipiodol for the preparation of radiolipiodol. The resulting radiolipiodol exhibited exceptional stability and ultra-high labeling efficiency (≥99%) and displayed notable intratumoral radionuclide retention and in vivo stability more than 2 weeks following locoregional injection in subcutaneous tumors in mice and orthotopic liver tumors in rats and rabbits. Given these encouraging findings, ¹⁸F was authorized as a radiotracer in radiolipiodol for clinical trials in HCC patients, and showed a favorable tumor accumulation, with a tumor-to-liver uptake ratio of ≥50 and minimal radionuclide leakage, confirming the feasibility of SHIFT for TARE applications. In the context of transforming from preclinical to clinical screening, the preparation of radiolipiodol by SHIFT represents an innovative physical strategy for radionuclide encapsulation. Hence, this work offers a reliable and efficient approach for TARE in HCC, showing considerable promise for clinical application (ChiCTR2400087731).

BACKGROUND:Warm-needling moxibustion can effectively treat knee osteoarthritis.Degeneration,injury and fracture of the anterior cruciate ligament can affect the local stability of the knee joint,and then induce the formation of knee osteoarthritis.Whether warm-needling moxibustion can repair the injured cruciate ligament and the mechanism of action are still unclear. OBJECTIVE:To observe the effects of warm-needling moxibustion on the morphology of the anterior cruciate ligament and the expression of insulin growth factor-1 and transforming growth factor-β in rabbits with knee osteoarthritis and to clarify the mechanism of anterior cruciate ligament repair by warm-needling moxibustion. METHODS:Thirty New Zealand rabbits were randomly divided into blank group,model group and warm-needling moxibustion group,with 10 rabbits in each group.Knee osteoarthritis model was established by plaster cast immobilization.The blank group was not intervened.Rabbits in the model group rabbits were fixed in a rabbit holder for 15 minutes every day.The warm-needling moxibustion group was treated with warm acupuncture,once a day,7 days as a course of treatment,a total of two courses.After treatment,the imaging changes of the anterior cruciate ligament were observed by MRI and MRI grading statistics were performed.Morphological changes of the anterior cruciate ligament were observed by transmission electron microscope and hematoxylin-eosin staining.mRNA and protein expressions of insulin growth factor-1 and transforming growth factor-β were detected by RT-PCR and western blot,respectively. RESULTS AND CONCLUSION:MRI examination:Compared with the blank control group,the anterior cruciate ligament in the model group was thickened,edematous,and partially torn,and the difference in grading statistics was statistically significant(P＜0.05).Compared with the model group,the anterior cruciate ligament in the warm-needling moxibustion group was slightly thickened,with mild edema and no tearing,and the difference in grading statistics was statistically significant(P＜0.05).General observation:In the model group,the surface of the anterior cruciate ligament was glossy and faded,with the edge being covered with flocculent periosteum and obvious tissue necrosis;in the warm-needling moxibustion group,the surface of the ligament was glossy,and the ligament was in a normal helical shape.Hematoxylin-eosin staining:In the model group,there was obvious tissue necrosis in the anterior cruciate ligament,a large number of new capillaries,loosely arranged fibroblasts and collagen fibers.In the warm-needling moxibustion group,there was a small amount of tissue necrosis and few new vessels in the anterior cruciate ligament,and the cells and collagen fibers were loosely and irregularly arranged.Transmission electron microscopy:In the model group,the fibers in the anterior cruciate ligament were arranged in a disordered way with uneven thickness and distribution,and there are more fibroblasts that were irregular in morphology;in the warm acupuncture group,the fibers were basically arranged longitudinally,with uneven thickness and distribution,and a small number of oval-shaped fibroblasts were observed.RT-PCR and western blot assay:mRNA and protein expressions of insulin growth factor-1 and transforming growth factor-β were significantly decreased in the model group compared with the blank control group(P＜0.05),but significant increased after treatment with warm-needling moxibustion(P＜0.05).To conclude,warm-needling moxibustion can alleviate anterior cruciate ligament injury and regulate the expression of insulin growth factor-1 and transforming growth factor-β to treat knee osteoarthritis.

To investigate the collective influence of sarcopenia on the extended prognosis of hospitalized elderly individuals with type 2 diabetes mellitus(T2DM).

To improve the current situation of multiple preoperative visits and evaluations for elderly patients and other patients with complex conditions, in December 2022, Peking Union Medical College Hospital established preoperative multidisciplinary evaluation clinic (shorted as joint clinic). The joint clinic established a multidisciplinary team, clarified service targets, and developed standardized clinic workflows to provide patients with a " one-stop" preoperative assessment(physical fitness assessment, nutritional assessment, and frailty assessment, etc.), nutritional optimization intervention, and prerehabilitation education and guidance services. This practice strengthened preoperative risk management, improved preoperative assessment efficiency, and ensured the safety of patients during the perioperative period. As of September 2023, the joint clinic had received a total of 128 patients, of which 86 underwent surgery after preoperative evaluation and prehabilitation optimization. The obesity rate, smoking rate, and number of frailty cases of these patients had decreased from 13.96%, 11.63%, and 18 at the time of visit to 9.30%, 4.65%, and 14 on the day before surgery, respectively. They had recovered well after surgery. This practice had improved the preoperative status of patients and created conditions for high-risk patients to undergo surgery smoothly, so as to provide references for other hospitals to carry out multidisciplinary collaborative preoperative evaluation works.

Objective:To investigate the surgical techniques and advantages of Ti-Robot-assisted surgery for pelvic fragility fractures in the elderly.Methods:A retrospective review was performed on geriatric patients presenting with pelvic fractures at the Orthopedics Department of Trauma, China-Japan Union Hospital of Jilin University from September 2019 to December 2022. Minimally invasive procedures were executed with the assistance of the Ti-Robot, and the therapeutic outcomes were appraised. The cohort comprised 24 patients aged ≥60 years, consisting of 6 men and 18 women, with a mean age of 66.1±4.9 years (range, 60-77 years). Fourteen patients sustained high-energy trauma, while 10 encountered low-energy trauma. Fracture classification utilized the FFP system proposed by Rommens and Hofmann. The cohort included 20 patients with FFP II fractures (5 males, 15 females; 4 of type IIa, 12 of type IIb, and 4 of type IIc) and 4 patients with FFP III fractures (1 male, 3 females; all type IIIa). The Matta standard assessment scale gauged fracture reduction, while the Gras classification, with Ti-Robot assistance, assessed screw positioning. Postoperative functionality was holistically assessed based on the Majeed quantitative evaluation system, focusing on pain intensity, sitting, standing, walking, and daily activities. The visual analogue scale (VAS) gauged pain levels in patients with type II fractures, pre and 72 hours post-surgery.Results:According to the Matta standard assessment scale, postoperative fracture reduction quality in 24 elderly patients showed 18 as excellent, 4 as good, and 2 as fair, yielding a 92% (22/24) combined excellent and good rate. Based on the Gras classification, 52 screws were rated as excellent and 7 as good, achieving a 100% positive rate. Utilizing Majeed's modified pelvic fracture evaluation system, postoperative functional recuperation revealed 19 patients as excellent and 5 as good. There were no reports of severe internal disease exacerbations, neurological manifestations, infections, or intraoperative extensive hemorrhaging, with all patients remaining stable. Fractures exhibited robust healing during follow-ups, averaging a recovery time of 3.5±0.7 months (range, 3-5 months). The VAS for 20 patients with FFP type II fractures decreased from 6.3±2.0 pre-surgery to 4.1±1.4 post-surgery ( t=6.14, P=0.003), signifying substantial pain mitigation. Conclusion:In the elderly with pelvic fragility fractures, particularly type II, securing with channel screws is viable. The Ti-Robot-assisted minimally invasive approach is advocated due to its potential to diminish surgical risks and expedite postoperative recuperation.

Objective To investigate the value of serum markers in the early diagnosis of liver cirrhosis with minimal hepatic encephalopathy (MHE). Methods A prospective analysis was performed for 81 patients who were hospitalized and treated in General Hospital of Ningxia Medical University from April 2020 to February 2022, and all these patients were diagnosed with hepatitis B cirrhosis based on clinical manifestation, laboratory examination, and radiological examination or liver biopsy. According to digital connection test A (NCT-A) and digital symbol test (DST), these patients were divided into simple cirrhosis group with 45 patients and MHE group with 36 patients. Related indices were measured, including liver function [alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transpeptidase (GGT), alkaline phosphatase (ALP), and total bilirubin (TBil)], albumin, blood ammonia, cholinesterase, and prothrombin time. The independent samples t -test was used for comparison of normally distributed continuous data between two groups; the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups, and the Kruskal-Wallis H test was used for comparison between multiple groups; the chi-square test was used for comparison of categorical data between groups. The logistic regression analysis and the area under the ROC curve (AUC) were used to investigate the predictive factors for MHE. Results Compared with the simple cirrhosis group, the MHE group had a significant increase in NCT-A score ( Z =-7.110, P < 0.001) and a significant reduction in DST score ( t =12.223, P < 0.001). The univariate analysis showed that there were significant changes in AST, albumin, prothrombin time, cholinesterase, and blood ammonia in the patients with MHE ( Z =-2.319, -2.643, -1.982, -6.594, and -5.331, all P < 0.05), while the multivariate analysis showed that only cholinesterase and blood ammonia were significant predictive factors (all P < 0.05) and were correlated with Child-Pugh score (all P < 0.05). Cholinesterase, blood ammonia, and their combination had an AUC of 0.925, 0.845, and 0.941, respectively, in the diagnosis of MHE, with an optimal cut-off value of 2966, 60, and 0.513, respectively. Conclusion Blood ammonia, cholinesterase, and their combined measurement have a potential clinical value in the early diagnosis of liver cirrhosis with MHE.
