ObjectiveTo investigate the effects of thyme herbal tea （BLX） on the proliferation of human coronavirus OC43 （HCoV-OC43） in vitro and in vivo. MethodThe chemical composition of BLX was analyzed by UPLC-MS. The cytotoxicity of BLX in HRT-18 cells and the effect of BLX treatment on the proliferation of HCoV-OC43 in cells were analyzed. Copies of viral gene were detected by real-time PCR. The effect of BLX treatment on the life cycle of HCoV-OC43 was detected by time-of-addition assay. The maximum tolerated dose of BLX and the influences of BLX on the body weight and survival time of suckling mice infected with HCoV-OC43 were determined. The expression of viral protein in the brain and lung tissue was analyzed by immunohistochemistry. ResultThere were 11 chemical components identified in BLX by UPLC-MS. BLX showed the 50% cytotoxic concentration （CC₅₀） of （13 859.56±319） mg·L^-1， the median inhibitory concentration （IC₅₀） of （1 439.09±200） mg·L^-1， and the selection index of 8.26-11.44 for HCoV-OC43 in HRT-18 cells. Compared with the cells infected with HCoV-OC43， BLX at the concentrations of 1 500， 1 000， 500 mg·L^-1 inhibited the proliferation of this virus （P<0.05， P<0.01）. BLX exhibited antiviral effect in the early stage of virus infection， and the inhibition role in the attachment stage was more significant than that in the entry stage （P<0.05）. In the suckling mice infected with HCoV-OC43， BLX at 1200 and 600 mg·kg^-1·d^-1 alleviated the symptoms， prolonged the survival period， reduced the death rate， and down-regulated the mRNA level of nucleocapsid protein in the mice. Moreover， BLX at 1 200 mg·kg^-1·d^-1 down-regulated the expression of nucleocapsid protein in the brain （P<0.01） and the lung （P<0.01）. ConclusionBLX contained multiple antiviral ingredients. It inhibited the proliferation of HCoV-OC43 both in vitro and in vivo by interference with viral attachment. This study provides theoretical reference for the treatment of acute respiratory tract infection with HCoV-OC43 and for further development and application of BLX.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Objective To explore the application value of telmisartan combined with calcium dobesilate in patients with non-dipper hypertension complicated with type 2 diabetes mellitus(T2DM).Methods A total of 260 patients with non-dipper hypertension complicated with T2DM in the endocrinology department of our hospital were selected in this study from January 2021 to December 2022.All the patients were randomly divided into telmisartan group(Tel,n=110)and telmisartan+calcium dobesilate group(Tel+Cal-dob,n=150).The blood pressure level,blood pressure rhythm changes,brachial flow mediated dilatation(FMD),carotid radial pulse wave velocity(crPWV),vasomotor factors[nitric oxide(NO),endothelin-1(ET-1),vascular endothelial growth factor(VEGF)]and the incidence of adverse reactions were compared between the two groups.Results There was no significant difference in general data and biochemical indexes between the two groups(P>0.05).After 3,6 and 12 months of treatment,the FMD and NO were higher,while the dSBP,dDBP,24 hSBP,24 hDBP,nSBP,nDBP,crPWV,ET-1 and VEGF were lower than before treatment in both groups(P<0.05).After 3,6 and 12 months of treatment,the FMD and NO were higher,while dSBP,dDBP,24 hSBP,24 hDBP,nSBP,nDBP,crPWV,ET-1 and VEGF were lower in Tel+Cal-dob group than in Tel group(P<0.05).After 3,6 and 12 months of treatment,the conversion rates of dipper blood pressure were higher in Tel+Cal-dob groupthan in Tel group(P<0.05).There was no significant difference in the incidence of adverse effects between the two groups(P>0.05).Conclusion Telmisartan combined with calcium dobesilate is effective in the treatment of patients with non-dipper hypertension complicated with T2DM.

Objective To evaluate the value of magnetic resonance spectroscopy (MRS) in the diagnosis of intracranial space-occupying lesions. Methods A total of 126 patients with intracranial space-occupying lesions in the First Affiliated Hospital of Xinjiang Medical University from 2019 to 2022 were enrolled and subjected to brain magnetic resonance imaging (MRI) and MRS examinations. The performance of MRI alone and in combination with MRS was evaluated and compared for diagnosis of intracranial space-occupying lesions. Results Tuberculoma (19.05%) and high-grade glioma (15.87%) were the intracranial space-occupying lesions most commonly diagnosed by MRI in combination with MRS. Radiologists confirmed the diagnosis of intracranial space-occupying lesions in 23.81% patients depending on MRI alone, and in 75.40% patients depending on MRI combined with MRS, with a 2.17-fold improvement (χ² = 67.07, P<0.01). The combination of MRI and MRS improved the accuracy of imaging diagnosis of intracranial space-occupying lesions in 70 (55.67%) patients compared with MRI alone. In addition, MRI in combination with MRS significantly improved the accuracy of differential diagnosis of high-grade glioma, low-grade glioma, cerebral infarct, tuberculoma, recurrent tumor, and radiation necrosis compared with MRI alone (P<0.01). Conclusion The efficacy of imaging diagnosis of intracranial space-occupying lesions can be improved by MRI in combination with MRS relative to MRI alone. The combined use of MRI and MRS may serve as a non-invasive tool for diagnosis of intracranial space-occupying lesions. In addition, the combination facilitates the differentiation between low- and high-grade gliomas, between high-grade glioma and tuberculoma, and between recurrent tumor and radiation necrosis.

LCH-2011 regimen)was referenced,and the targeted drug Dabrafenib was added to treat those with the BRAF-V600E mutation.The clinical characteristics,BRAF-V600E mutation status,and treatment response between the single-system LCH(SS-LCH)group and the multisystem LCH(MS-LCH)group were summarized.Survival curves were plotted using the Kaplan-Meier method,and the Log-Rank test was used to compare the survival rates between the two groups.Results This study included a total of 31 cases,with 18 males and 13 females.The median age of onset was 10 months(ranging from 1 to 84 months).9 cases were SS-LCH,and 22 cases were MS-LCH,with 5 cases experiencing pituitary involvement/diabetes insipidus.Among the 27 cases that underwent BRAF-V600E mutation testing,20 were positive(3 cases in the SS-LCH group,with a positivity rate of 37.5%;17 cases in the MS-LCH group,with a positivity rate of 89.5%).The difference in the BRAF-V600E mutation positivity rate between the two groups was statistically significant(P = 0.011).The median follow-up time was 24 months(ranging from 3 to 62 months).The effective rate after 6 weeks of induction chemotherapy was 88.9%in the SS-LCH group(8/9)and 81.8%in the MS-LCH group(18/22).The observed progression-free rate at the end of the observation period reached 29.0%(9/31).All three deaths occurred in the MS-LCH group with involvement of high-risk organs.There was no statistically significant difference in the overall survival rate between the SS-LCH and MS-LCH groups,as well as between the BRAF-V600E mutation positive and negative groups(χ2 = 1.156,0.437;P = 0.282,0.508).Conclusion LCH in children is more common in infants and young children,with a high incidence of BRAF-V600E gene mutation in affected children,and is often seen in MS-LCH.Dabrafenib may help improve the prognosis of children with BRAF-V600E mutation.

Objective:To investigate the nutritional risk and the incidence of malnutrition in children with recurrent abdominal Henoch Schonlein purpura(HSP), and observe the changes in the incidence of malnutrition after nutritional intervention.Methods:We retrospectively analyzed 90 children diagnosed with recurrent HSP in our hospital from 2017 to 2019.The cases were divided into two groups according to whether nutritional intervention was performed.The cases from January 2017 to May 2018 were chosen as the control group( n=42), and the cases from June 2018 to December 2019 were chosen as the experimental group( n=48). Based on the treatment of the primary disease, the high nutritional risk cases in experimental group were treated with extensively hydrolysed infant formula for nutritional intervention.The children were evaluated for nutritional risk with the STRONGkids nutrition tool.According to the score results, they were divided into high nutritional risk group and medium nutritional risk group.The Z score was used to evaluate malnutrition, and the degree of malnutrition was compared at admission and discharge. Results:Eighty-one children (90.0%) with recurrent abdominal allergic purpura had a high nutritional risk, 9 cases (10.0%)had a medium nutritional risk.There was no significant difference in the incidence of moderate and severe malnutrition between experimental group and control group at admission[39.6% (19/48) vs.40.5% (17/42), P>0.05]. The incidence of moderate and severe malnutrition in control group was higher than that in experimental group at discharge[66.7% (28/42) vs.22.9% (11/48), P<0.05]. Conclusion:In children with recurrent abdominal HSP, due to severe gastrointestinal symptoms and a high incidence of high nutritional risk, nutritional intervention with extensively hydrolysed infant formula can avoid the occurrence or aggravation of iatrogenic malnutrition during hospitalization.

Objective:To evaluate the role of adiponectin in sevoflurane pretreatment-induced improvement in cognitive function in mice with myocardial ischemia/reperfusion (I/R).Methods:Thirty SPF healthy adult male wild-type C57 mice, aged 8-10 weeks, weighing 20-25 g, were divided into 3 groups ( n=10 each) using a random number table method: sham operation group (group Sham), myocardial I/R group (group MI/R) and sevoflurane pretreatment group (group SP). Another 10 SPF healthy male adiponectin knockout SPF mice, aged 8-10 weeks, weighing 20-25 g, were selected and served as APNKO group.Myocardial I/R was induced by 30 min occlusion of anterior descending branch of left coronary artery followed by reperfusion.In SP and APNKO groups, sevoflurane pretreatment included 3 cycles of 10-minute inhalation of 2% sevoflurane-93% O 2-5% CO 2 interspersed with 15-minute inhalation of 95% O 2-5% CO 2, and then the model was established.At 1, 2 and 4 days of reperfusion, cognitive function was assessed by Morris water maze test. Results:There was no significant difference in swimming velocity at each time point between the 4 groups ( P>0.05). Compared with group Sham, the escape latency was significantly prolonged, and the frequency of crossing the original platform was decreased at each time point in group MI/R ( P<0.05). Compared with group MI/R, the escape latency was significantly shortened, and the frequency of crossing the original platform was increased at each time point in group SP ( P<0.05). Compared with group SP, the escape latency was significantly prolonged, and the frequency of crossing the original platform was decreased at each time point in group APNKO ( P<0.05). Conclusion:Adiponectin is involved in the process of sevoflurane pretreatment-induced improvement in cognitive function in mice with myocardial I/R.

Purpose: RIOK1 has been proved to play an important role in cancer cell proliferation and migration in various types of cancers—such as colorectal and gastric cancers. However, the expression of RIOK1 in breast cancer (BC) and the relationship between RIOK1 expression and the development of BC are not well characterized. In this study, we assessed the expression of RIOK1 in BC and evaluated the mechanisms underlying its biological function in this disease context. Materials and Methods: We used immunohistochemistry, western blot and quantitative real-time polymerase chain reaction to evaluate the expression of RIOK1 in BC patients. Then, knockdown or overexpression of RIOK1 were used to evaluate the effect on BC cells in vitro and in vivo. Finally, we predicted miR-204-5p could be a potential regulator of RIOK1. Results: We found that the expression levels of RIOK1 were significantly higher in hormone receptor (HR)–negative BC patients and was associated with tumor grades (p=0.010) and p53 expression (p=0.008) and survival duration (p=0.011). Kaplan-Meier analysis suggested a tendency for the poor prognosis. In vitro, knockdown of RIOK1 could inhibit proliferation, invasion, and induced apoptosis in HR-negative BC cells and inhibited tumorigenesis in vivo, while overexpression of RIOK1 promoted HR-positive tumor progression. MiR-204-5p could regulate RIOK1 expression and be involved in BC progression. Conclusion These findings indicate that RIOK1 expression could be a biomarker of HR-negative BC, and it may serve as an effective prognostic indicator and promote BC progression.

Objective: To investigate the clinical and laboratory features of Aeromonas bacteremia in patients with hematological diseases, and provide evidence for the prevention and treatment of Aeromonas infection. Methods: A retrospective study of patients with bloodstream infection of Aeromonas in our hospital from January 2014 to December 2018 was carried out. The clinical characteristics, antimicrobial susceptibility, infection seasons, antimicrobial therapy and evolution were analyzed. Results: A total of 42 patients with hematological diseases had Aeromonas bloodstream infection within 5 years. Among them, 39 cases (92.9%) of bloodstream infection occurred in the stage of neutropenia. The median time of fever was 4 (1-27) d, 22 (52.4%) patients only had fever, 6 (14.3%) with gastrointestinal symptoms (abdominal pain, diarrhea, nausea, upper gastrointestinal bleeding) , 8 (19.0%) with pulmonary infection, 13 (31.0%) with skin and soft tissue infections. Seven patients (16.7%) died with skin and soft tissue infection. The resistance of Aeromonas to carbapenems was 68.3%-70.7%, while the resistance rate to cephalosporins, quinolones and aminoglycosides were less than 10%. Conclusions Aeromonas bacteremia in patients with hematological diseases mainly occur in the neutropenia stage, usually with symptom like fever. The mortality is increased when accompanied by skin and soft tissue infection. Antibiotic use should be based on susceptibility results, and avoid the use of carbapenems.
