A 20-year-old male patient with T-lymphoblastic lymphoma/leukemia received 9/10 human leukocyte antigen-compatible unrelated peripheral blood stem cell transplantation. He was transplanted with 5.91×10 8 mononuclear cells/kg and 2.88×10 6 CD34 + cells/kg, and neutrophil engraftment was obtained at +11 days and platelet engraftment at +9 days. After transplantation, he presented with repeatedly increased serum creatinine levels, BK virus (BKV) -associated hemorrhagic cystitis, and BKV viremia. BK virus nephropathy was diagnosed based on renal biopsy and metagenomic next-generation sequencing. After adjusting the immunosuppressant, intravenous immunoglobulin, and donor lymphocyte infusion treatment, the patient’s renal function deteriorated progressively, and he eventually died of multiple organ failure at +289 days.

Objective:To analyze the clinical characteristics and treatment outcomes of central nervous system（CNS）mucormycosis following allogeneic hematopoietic stem cell transplantation（allo-HSCT）.Methods:Clinical data of 6 patients diagnosed with CNS mucormycosis after allo-HSCT at Henan Cancer Hospital between January 2020 and December 2024 were retrospectively collected. The patients' clinical manifestations，laboratory findings，imaging features，treatment regimens，and outcomes were analyzed.Results:The incidence of CNS mucormycosis post-allo-HSCT was 0.7%（6/851）. The main clinical manifestations included impaired consciousness（5 cases），convulsions（3 cases），headache（2 cases），hemiplegia（1 case），ptosis（1 case），and mydriasis with sluggish light reflex and incomplete eye closure（1 case）. The median time from transplantation to the onset of neurological symptoms was 138 days（94-572 days）. Metagenomic next-generation sequencing（mNGS）of cerebrospinal fluid identified Rhizopus spp.（2 cases）， Rhizomucor spp.（2 cases），and Absidia spp.（2 cases）. Cranial MRI performed in five patients revealed multiple mass or patchy lesions in various regions；one patient underwent cranial CT，which showed patchy hypodense lesions in multiple areas. All patients received antifungal therapy，with 2 cases receiving combined intrathecal injection of amphotericin B liposomes；five patients died，and one survived. Conclusions:CNS mucormycosis is a rare but severe complication after allo-HSCT. Its clinical and radiological features are non-specific，posing diagnostic challenges. Intravenous administration of liposomal amphotericin B at full dosage，combined with intrathecal injection，may improve treatment efficacy.

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.

Objective To understand the prevalence status quo of mild cognitive impairment(MCI)in the elderly people by conducting the investigation on the elderly people in somewhere,and to explore the influ-encing factors of MCI in the elderly people to provide reference for constructing the MCI localized computer screening and diagnosis system in the elderly.Methods A multi-stage sampling method was used to deter-mine the survey population.The self-made questionnaires,mini mental state examination(MMSE),geriatric depression screening scale(GDS-15),geriatric anxiety screening scale,geriatric psychiatric symptoms scale,and daily living ability scale were used to collect or evaluate basic information,cognitive impairment,depres-sion,anxiety,psychiatric symptoms,and daily living ability of elderly people from March 5,2022 to July 22,2022.The index system affecting MCI was screened by the receiver operating characteristic(ROC)curve and unconditional binary logistic regression,and the localized computer screening diagnosis system was construc-ted.Results A total of 1 004 elderly individuals were surveyed,among them there were 262 cases(26.1％)of MCI,194 cases(19.3％)of anxious state,21 cases(2.1％)of depression,313 cases(31.2％)of psychotic symptoms and 32 cases(3.2％)of impaired ability of activities of daily living(ADL).The ROC curve analysis showed that the area under the curves(AUC)of depression,anxiety and psychotic symptoms for predicting MCI in elderly individuals were 0.640,0.645,and 0.586,respectively.AUC of anxiety combined with depres-sion(anxiety+depression),depression+psychotic symptoms,anxiety+psychotic symptoms and depression+anxiety+psychotic symptoms were 0.676,0.652,0.645 and 0.676,respectively.The multivariate analysis found that the age,whether or not anyone close to you died in the last two years,ability of activities of daily living,anxiety degree,whether or not having psychotic symptoms,education level,whether or not having joint habitation with the family members and suffering from multiple chronic diseases were the influencing factors of MCI.Conclusion The age,education level,death of close persons in the past two years,ability to live daily life,depression,and psychotic symptoms could serve as the indicators system of the MCI localized computer screening and diagnosis system.

Systemic mastocytosis (SM) with RUNX1-RUNX1T1 positive acute myeloid leukemia (AML) is a rare myeloid tumor with no standard treatment. Two cases of SM patients with RUNX1-RUNX1T1 positive AML treated with sequential avapritinib after allogeneic hematopoietic stem cell transplantation (allo-HSCT) were reported in Henan Cancer Hospital. Mast cell in bone marrow disappeared, C-KIT mutation and RUNX1-RUNX1T1 fusion gene remained negative. Allo-HSCT sequential avapritinib is an effective treatment for SM patients with RUNX1-RUNX1T1 positive AML.

Objective:To investigate the efficacy and safety of avapritinib in the treatment of molecular biologically positive core binding factor-acute myeloid leukemia (CBF-AML) with KIT mutation after allogeneic hematopoietic stem cell transplantation (allo-HSCT) .Methods:We retrospectively analyzed the clinical data of six patients with molecular biologically positive CBF-AML with KIT mutation after allo-HSCT, who were treated with avapritinib at Henan Cancer Hospital from December 2021 to March 2023, and evaluated the efficacy and safety of avapritinib.Results:After 1 month of treatment with avapritinib, the transcription level of the fusion gene decreased in six patients, and the transcription level decreased by ≥1 log in five patients. In four patients who received avapritinib for ≥3 months, the fusion gene turned negative, and the median time to turn negative was 2.0 (range: 1.0-3.0) months. Up to the end of follow-up, four patients had no recurrence. The most common adverse reaction of avapritinib was myelosuppression, including neutropenia in two cases, thrombocytopenia in two cases, and anemia in one case. The non-hematological adverse reactions were nausea in two cases, edema in one case, and memory loss in one case, all of which were grades 1-2.Conclusion:Avapritinib was effective for molecular biologically positive CBF-AML patients with KIT mutation after allo-HSCT. The main adverse reaction was myelosuppression, which could generally be tolerated.

This article introduces the clinical experience of professor CHEN Gui-Zhen in treating premature ovarian insufficiency(POI).According to professor CHEN Gui-Zhen,the etiology and pathogenesis of POI is congenital insufficiency of kidney essence,failure of acquired source of production and transformation of spleen and stomach,and failure of liver to maintain free movement of qi,which leads to failure of production and transformation source of sex-stimulating essence,disharmony of Chong and Conception Channels.Therefore,professor CHEN Gui-Zhen emphasizes the principle of"tonifying kidney and replenishing sex-stimulating essence,invigorating the spleen and dispersing the stagnated liver-energy,regulating Chong and Conception Channels"during treatment.As for the clinical acupoint selection,the combination of back-shu and front-mu points method is valued,as for the acupuncture technique,professor CHEN uses the flying needle therapy to calm mind,and straight-side acupuncture to strenghthening qi,and acupoint catgut embedding therapy skillfully,she trinity the above treatment methods,and combined use of acupoint catgut embedding and medicine.The treatment of POI is based on syndrome differentiation,and the purpose of harmony of Chong and Conception Channels is finally achieved.

Objective: To study the effect of diurnal temperature range on the number of elderly inpatients with ischemic stroke in Hunan Province. Method: Demographic and disease data, meteorological data, air quality data, population, economic and health resource data of elderly inpatients with ischemic stroke were collected in 122 districts/counties of Hunan Province from January to December 2019. The relationships between the diurnal temperature range and the number of elderly inpatients with ischemic stroke were analyzed by using the distributed lag non-linear model, including the cumulative lag effect of the diurnal temperature range in different seasons, extremely high diurnal temperature range and extremely low diurnal temperature range. Results: In 2019, 152 875 person-times were admitted to the hospital for ischemic stroke in the elderly in Hunan Province. There was a non-linear relationship between the diurnal temperature range and the number of elderly patients with ischemic stroke, with different lag periods. In spring and winter, with the decrease in diurnal temperature range, the risk of admission of elderly patients with ischemic stroke increased (P_trend<0.001, P_trend=0.002);in summer, with the increase in diurnal temperature range, the risk of admission of elderly patients with ischemic stroke increased (P_trend=0.024);in autumn, the change in the diurnal temperature range would not cause a change in admission risk (P_trend=0.089). Except that the lag effect of the extremely low diurnal temperature range in autumn was not obvious, the lag effect occurred in other seasons under extremely low and extremely high diurnal temperature ranges. Conclusion: The high diurnal temperature range in summer and the low diurnal temperature range in spring and winter will increase the risk of admission of elderly patients with ischemic stroke, and the risk of admission of elderly patients with ischemic stroke will lag under the extremely low and extremely high diurnal temperature ranges in the above three seasons.
