Objective To analyze the clinical characteristics of immune checkpoint inhibitor(ICI)-related hepatotoxicity(ICIH)in cancer patients.Methods A retrospective analysis was conducted on clinical data of cancer patients with ICIH from January 2019 to December 2024.Patients with Grade 1-2 liver injury were defined as the mild group,and those with Grade 3-4 liver injury were defined as the severe group.Results Among 13 patients with ICIH,10(76.92%)were males and 3(23.08%)were females,with a mean age of 67.8±5.2 years.Twelve patients(92.3%)were aged 60 years or above.ICIH first occurred between cycle 1 and cycle 14 after initial treatment,with the highest incidence observed within cycles 1-5.Combination therapy(combination chemotherapy or targeted agents)was used in 10 patients(76.92%).Among the 13 patients,the distribution of liver injury grades was as follows:1 case of Grade 1(7.69%),2 cases of Grade 2(15.38%),5 cases of Grade 3(38.46%),and 5 cases of Grade 4(38.46%).Liver injury types included hepatocellular(38.46%),cholestatic(38.46%),and mixed(23.08%).After drug discontinuation and supportive care,9 patients(69.23%)fully recovered,2(15.38%)improved,and 2(15.38%)showed no improvement.No significant differences were observed between the mild and severe groups in terms of age,body mass index,baseline lymphocyte count,platelet count,neutrophil count,monocyte count,alanine aminotransferase,aspartate aminotransferase,lactate dehydrogenase,alkaline phosphatase,lymphocyte-to-monocyte ratio,neutrophil-to-lymphocyte ratio,and platelet-to-lymphocyte ratio(P>0.05).Conclusion ICIH typically occurs within 1 to 5 cycles after ICI administration,with non-specific clinical manifestations,which lead to a diagnosis of exclusion.Despite a generally favorable prognosis,severe ICIH can be fatal,particularly in patients with primary liver cancer.Prompt discontinuation of ICIs and initiation of Corticosteroid therapy can lead to timely improvement of patient's condition.

Background: and Purpose Depression is common and debilitating illness accompanying many neurological disorders including non-traumatic subarachnoid hemorrhage (SAH). The aim of this systematic review was to identify and critically appraise all published studies that have reported the frequency, severity and time course of depression after SAH, the factors associated with its development and the impact of depression on patients’ quality of life after SAH. Methods: The PubMed database was searched for studies published in English that recruited at least 40 patients (>18 years old) after SAH who were also diagnosed with depression. Results: Altogether 55 studies covering 6,327 patients met study entry criteria. The frequency of depression ranged from 0% to 61.7%, with a weighted proportion of 28.1%. Depression remained common even several years after the index SAH. Depression after SAH was associated with female sex, premorbid depression, anxiety, substance use disorders or any psychiatric disorders, and coping styles. Comorbid cognitive impairment, fatigue, and physical disability also increased the risk of depression. Aneurysmal SAH and infarction may be related to depression as well. Depression reduces the quality of life and life satisfaction in patients after SAH. Conclusions Depression is common after SAH and seems to persist. Further research is needed to clarify its time course and identify the neuroendocrine and neurochemical factors and brain circuits associated with the development of post-SAH depression. Randomized controlled treatment trials targeting SAH-related depression are warranted.

OBJECTIVE： To evaluate the effectiveness of trolamine for preventing and treating radiation dermatitis （RD） and evidence quality， and to provide reference for clinical use. METHODS： Retrieved from PubMed， Cochrane library， Embase， CNKI， Wanfang and VIP database， randomized controlled trials （RCTs） about trolamine （trial group） versus usual care （control group） for preventing and treating RD were collected. After data extraction， Cochrane bias risk assessment tool 5.0.2 was used to assess the bias risk， and Rev Man 5.3 statistical software was used to perform the Meta-analysis. GRADE evidence quality grading system was used to evaluate the evidence quality of outcome indexes. RESULTS： Seven RCTs were included， involving 782 patients. Results of Meta-analysis showed that there was no statistical significance in total incidence of RD [OR＝0.50， 95％CI （0.23， 1.11）， P＝0.09]， and the incidence of grade Ⅰ RD [OR＝1.32， 95％CI（0.96，1.81）， P＝0.09]， grade Ⅱ RD [OR＝1.07， 95％CI（0.80，1.42）， P＝0.66]， grade Ⅲ RD [OR＝0.69， 95％CI（0.45，1.04）， P＝0.07] or grade Ⅳ RD [OR＝0.43， 95％CI（0.17，1.05）， P＝0.07] between 2 groups. Results of Grade evidence quality evaluation showed that total incidence of RD， and the incidence of grade Ⅱ RD and grade Ⅳ RD were recommended by moderate-level evidence in 2 groups， while the incidence of grade Ⅰ and grade Ⅲ RD were recommended by low-level evidence. CONCLUSIONS： Trolamine is not effective in preventing and treating RD， and can not reduce the incidence of RD.

Objective To analyze how enterovirus D68 (EV-D68) protease 2A affects the anti-vi-ral interferon typeⅠ(IFN-Ⅰ) pathway in 293T cells following infection. Methods Western blot was used to detect the expression of recombinant protease 2A, IFN-α and signal transducers and activators of tran-scription 1 (STAT1) at protein level. Expression of EV-D68 viral protein (VP1) and protease 2A was ana-lyzed by immunofluorescence at different time points. Cytopathic effects were recorded to calculate 50％ cell culture infective dose ( CCID50 ) . Expression of the genes involved in the anti-viral IFN-Ⅰ pathway was measured by real-time PCR (RT-PCR). Results The recombinant plasmid pCLIPf-2A was successfully constructed and the expression of recombinant protease 2A could be detected by Western blot 24 h after transfection. The recombinant protease 2A promoted the proliferation of EV-D68 at the late stage of infection and induced the production of IFN-α. Expression of the genes involved in the anti-viral IFN-Ⅰ pathway at mRNA level was up- or down-regulated to different degrees with various trends in different groups following infection. Expression of STAT1 was enhanced in all groups. Conclusions EV-D68 protease 2A promoted the activation of anti-viral IFN-Ⅰpathway in response to viral infection and enhanced the proliferation of virus at the late stage of infection.

OBJECTIVETo explore the effect and mechanism of flavones of buckwheat flower and leaf (FBFL) on lowering blood glucose and improving insulin resistance in type 2 diabetic rats.

METHODSeventy healthy male Wistar rats were used in this trial. Ten of them were selected randomly as normal group; the others were given fat milk by intragastric administration daily, from the 14th day on, low dose tetraoxypyrimidine was added by intraperitoneal injection every other day for three times. Rats with fasting (72 hours after the last injection) blood sugar > or = 16.7 mmol x L(-1) and K(IPT) < 60% of normal group were selected as type 2 diabetic model with insulin resistance, which were randomly divided into 5 groups: model group. LGLT group; low, moderate and high dosage FBFL groups (L-FBFL; M-FBFL; H-FBFL). Every rat was treated accordingly for 4 weeks; then FBG, FFA, INS were detected and ISI was calculated to evaluate the degree of insulin resistance. Liver PTP1B expression was determined by immunohistochemistry method. staining were observed by light microscopy.

RESULTFBFL could dose-dependently inhibit the rising of FBG, FFA, INS, improve the state of insulin resistance and reduce the expression level of liver PTP1B.

CONCLUSIONFBFL could effectively improve insulin resistance in type 2 diabetic rats induced by tetraoxypyrimidine and fat milk and showed dose-dependence relationship.

Aim To investigate the influence of total fl avones of buckwheat flower (TFBF) on the productivity of the non-enzymatic advanced glycation end products (AGEs) in vivoand vitro. Methods TFBF in different dosages (0.1 g?kg -1?d -1,0.2 g?kg -1?d -1,0.4 g?kg -1?d -1) was taken orally by streptozotocin-induced diabetic rats for 12 wk. After the treatment, blood glucose, fructosamine and AGEs in plasma and kidney were measured. Meanwhile, glucose and bovine serum albumin (BSA) were incubated with TFBF at different concentrations (0.01 mg?L -1,0.05 mg?L -1,0.10 mg?L -1) respectively for 4,8,12 wk.The fluorescence intensity of glycated BSA was detected by a spectrophotometer BSA was detected spectrophotometer.Results TFBF significantly lowered the level of blood glucose in diabetic rats (P
