Objective To assess the value of magnetic resonance imaging compilation(MAGiC)sequence in predicting lympho-vascular space invasion(LVSI)in early cervical cancer.Methods The data of 48 patients with cervical cancer confirmed by pathology were collected retrospectively,and classified into LVSI-positive group(n=29)and LVSI-negative group(n=19)according to postop-erative pathological results.MAGiC sequence images of patients were obtained before injecting contrast agents,then the region of interest(ROI)was delineated along the largest dimension edge of the lesion,and T1,T2 and proton density(PD)values were automatically generated by the software.Predictors were screened by univariate analysis and receiver operating characteristic(ROC)curves were drawn to assess their diagnostic efficacy for predicting LVSI in cervical cancer.Results Significant differences were found in T1 and PD values between LVSI-positive and LVSI-negative groups(P=0.003,P=0.017).There were no significant differences in T2 values between the two groups(P=0.414).The area under the curve(AUC)for T1 and PD values to predict LVSI status were 0.73 and 0.721,respectively.Conclusion LVSI-positive group of cervical cancer has lower T1 and PD values than LVSI-negative group based on MAGiC sequence.The MAGiC sequence has a certain application value for predicting LVSI status in early cervical cancer.

Objective To observe the value of MRI for differential diagnosis of ovarian granulosa cell tumor(OGCT)and ovarian thecoma-fibroma(OTF).Methods Data of 37 females with OGCT(OGCT group)and 74 with OTF(OTF group)were retrospectively analyzed.MRI parameters were compared between groups.Multiple logistic regression analysis was performed,and the efficacy of each parameter alone and their combination for distinguishing OGCT and OTF were observed.Results Significant differences of cystic-solid classification,degree of cystic changes,the maximum diameter of cyst area of lesions,T2WI signal,enhancement degree and apparent diffusion coefficient(ADC)of the solid part of lesions,presence of honeycomb sign/cheese sign,presence of tumor blood vessels and bleeding were found between groups(all P＜0.05).Degree of cystic changes,ADC and presence of honeycomb sign/cheese sign were impact factors of MRI for distinguishing OGCT and OTF.The area under the curve(AUC)of the above three for distinguishing OGCT and OTF was 0.834,0.868 and 0.744,respectively,and of the combination was 0.934,greater than any alone(all P＜0.05).Conclusion MRI features such as degree of cystic changes,ADC and presence of honeycomb sign/cheese sign were helpful for distinguishing OGCT and OTF.

Aim To establish a gait analysis system based on DeepLabCut(DLC)algorithm for evaluating motor function in aged mice.Methods Based on DLC algorithm in deep learning technology,treadmill device and fully closed design were used in the system,including software and hardware.This system was applied to evaluate gait characteristics of mice due to aging un-der different movement modes.Correlation analysis was used to explore the effects of body weight and body length on gait indica-tors.Results This system realized the synchronous analysis of three-dimensional gait(lateral and ventral plane)of mice at specific gait speed,and automatically quantified 47 gait indica-tors.Using this system,it was found that during walking(15 cm·s-1),the standard deviation of body turning angle decreased,forelimb sway duration,standard deviation of knee angle,mean outward angles of left and right hind paw increased in 8 and 15 month-old mice,compared with 2-month-old mice.However,15-month-old mice showed decreased walking frequency,and in-creased stride width,total duration of double support,and knee extension and contraction distance.In addition,at trot(20 cm·s-1),15-month-old mice were unable to walk steadily,and 8-month-old mice had increased total duration of double support and mean outward angles of left hind paw,compared with 2-month-old mice.Correlation analysis revealed that indicators like walking frequency,stride width,forelimb sway duration,total duration of double support,standard deviation of knee an-gle,knee extension and contraction distance,were not affected by changes in body weight and body length.Conclusions The gait analysis system based on DLC algorithm can achieve a more sensitive,accurate and comprehensive evaluation of the gait of aged mice,distinguishing the gait characteristics of aged mice to maintain gait stability,and selecting behavioral indicators that better reflect the gait changes of aged mice.It provides a meth-odological basis for more effective assessment of efficacy and side effects of drugs for anti-aging and anti-decline of motor coordina-tion in the future.

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.

The aim of this study was to explore the effects of Huangqin Tang(HQT) on the NLRP3/Caspase-1 signaling pathway in mice with DSS-induced ulcerative colitis(UC). C57BL/6J mice were randomly divided into a blank group, a model group(DSS group), and low-, medium-and high-dose HQT groups(HQT-L, HQT-M, and HQT-H), and western medicine mesalazine group(western medicine group). The UC model was induced in mice. Subsequently, the mice in the HQT-L, HQT-M, HQT-H groups, and the western medicine group were given low-, medium-, high-dose HQT, and mesalazine suspension by gavage, respectively, while those in the blank and DSS groups were given an equal volume of distilled water by gavage. After 10 days of administration, the body weight, DAI scores, and colonic histopathological score of mice in each group were determined. The levels of IL-6, IL-10, IL-1β, and TNF-α in serum were determined by ELISA. The mRNA expression of NLRP3 and Caspase-1 in colon tissues was determined by RT-qPCR. The protein expression of NLRP3 and Caspase-1 in colon tissues was detected by immunohistochemistry. The results showed that compared with the blank group, the DSS group showed decreased body weight of mice and increased DAI scores and intestinal histopathological score. Compared with the DSS group, the HQT groups and the western medicine group showed improved DAI scores, especially in the HQT-M, HQT-H, and the western medicine groups(P<0.05). The intestinal histopathological scores of the HQT groups and the western medicine group significantly decreased, especially in the HQT-M, HQT-H, and the western medicine groups(P<0.05). In addition, compared with the blank group, the DSS group showed elevated expression of NLRP3 and Caspase-1 in colon tissues, increased serum levels of IL-6, IL-1β, and TNF-α, and decreased IL-10 level. Compared with the DSS group, the HQT groups and the western medicine group displayed decreased expression of NLRP3 and Caspase-1 in colon tissues, reduced serum levels of IL-6, IL-1β, and TNF-α, and increased IL-10 level. The improvement was the most significant in the HQT-H group and the western medicine group(P<0.01). In conclusion, HQT may reduce the expression of NLRP3 and Caspase-1 in colon tissues, reduce the se-rum levels of IL-6, IL-1β, and TNF-α, and increase the expression of IL-10 by regulating the classic pyroptosis pathway of NLRP3/Caspase-1, thereby improving the symptoms of intestinal injury and inflammatory infiltration of intestinal mucosa in DSS mice to achieve its therapeutic effect.

Hepatocellular carcinoma (HCC) is the most common primary hepatic malign-ancy in clinic. The prognosis of patients remains extremely poor because of the high malignancy and easy recurrence and metastasis of HCC. In recent years, the roles of platelets in promoting the malignant progression of HCC have increasingly attracted much attention. It is known that platelets could promote HCC cells proliferation and invasion through tumor microenvironment. On the other hand, platelets are capable to promote HCC cells distant metastasis by facilitating tumor cells evasion of immune surveillance. Besides, the platelet-derived growth factors and proangiogenic factors are also involved in the proliferation, invasiveness, and neovascularization of HCC. In addition, patients with HCC normally have a background of cirrhosis, and it is still controversial that whether the thrombocytopenia by portal hypertension and hypersplenism can promote the malignant progress of HCC. In view of this, the diagnostic and prognostic value of platelet levels, as well as platelet-associated scores in HCC have increasingly become research focus. The authors elaborate the detailed mechanisms of platelets in malignant progression of HCC, and discuss the recent research progress of platelets as effective diagnostic or prognostic tools for the assessment of HCC, which is of great importance to optimize the current treatment regimen and explore novel therapeutic strategies against HCC.

OBJECTIVE: To investigate the protective effect of Chinese herbal formula Huangqin Decoction (HQD) on ulcerative colitis mouse model induced by dextran sulphate sodium (DSS) and human intestinal epithelial cell injury induced by tumour necrosis factor-α (TNF-α). METHODS: In vivo, 30 male C57BL/6 mice were divided into 5 groups using a random number table (n=6 per group), including control, DSS, 5-aminosalicylic acid (5-ASA), HQD low- (HQD-L) and high-dose (HQD-H) groups. The colitis mouse model was established by 3% (w/v) DSS water for 5 days. Meanwhile, mice in the HQD-L, HQD-H and 5-ASA groups were administrated with 100, 200 mg/kg HQD or 100 mg/kg 5-ASA, respectively, once daily by gavage. After 9 days of administration, the body weight, disease activity index (DAI) score and colon length of mice were measured, the pathological changes of colons were analyzed by hematoxylin-eosin staining (HE) staining, and the levels of serum interleukin (IL)-6, IL-1β and TNF-α were measured by enzyme linked immunosorbent assay. In vitro, the human colon epithelial normal cells (FHC cells) were exposed to HQD (0.6 mg/mL) for 12 h and then treated with TNF-α (10 ng/mL) for 24 h. The tight junction (TJ) protein expression levels of Claudin-4 and Occludin, and the protein phosphorylation levels of p65 and inhibitor of nuclear factor kappaB (NF-κB)-α (IκBα) were measured by Western blot. RESULTS: In vivo, compared with the DSS group, HQD-H treatment attenuated the weight loss and reduced DAI score of mice on the 8th day (P<0.05). Moreover, HQD-H treatment ameliorated the colon shortening in the DSS-induced colitis mice (P<0.05). HE staining showed HQD attenuated the pathological changes of colitis mice, and the histological scores of HQD-H and 5-ASA groups were significantly decreased compared with the DSS group (P<0.05). Meanwhile, HQD-H and 5-ASA significantly decreased the serum IL-1β, IL-6 and TNF-α levels of mice (P<0.05). In vitro experiments showed that HQD up-regulated Occludin and Claudin-4 protein expressions and inhibited p-p65 and p-IκBα levels in FHC cells compared with the TNF-α group (P<0.05). CONCLUSION HQD significantly relieved the symptoms in DSS-induced colitis mice by inhibiting pro-inflammatory cytokines expression and maintained the homeostasis of TJ protein in FHC cells by suppressing TNF-α-induced NF-κB activation.
