To summarize Professor GAO Shuzhong's clinical experience in treating idiopathic tinnitus with a combination of acupuncture and Chinese meteria medica. It is believed that idiopathic tinnitus is mostly caused by weak lungs and spleen， kidney essence deficiency， liver constraint transforming into fire， and binding constraint of heart qi. Treatment advocates the combination of acupuncture and Chinese meteria medica in clinical practice. Acupuncture treatment mainly focus on the method of opening the orifices by syndrome identification in combination with Ermen （TE 21）， Tinggong （SI 19）， Tinghui （GB 2）， Shenmai （BL 62） to regulate qi and blood， and supporting with Baihui （GV 20）， Yintang （EX-HN 3）， Taichong （LR 3）， and Yanglingquan （GB 34） to soothe the liver， resolve constraint， and calm the mind. Oral administration of Chinese medicinal prescription usually includes modified Yiqi Congming Decoction （益气聪明汤） and Tongqi Powder （通气散）， and the external administration of Chinese medicinal prescription can apply self-prescribed Wenqing Powder （温清散） to navel moxibustion.

Hepatocellular carcinoma （HCC） with biliary duct tumor thrombus （BDTT） is currently not common in clinical practice and is easily misdiagnosed， and previously， it was often considered an advanced stage of the disease with a poor prognosis， making its treatment challenging. However， in-depth studies in recent years have gradually deepened our understanding of this disease， leading to significant changes in diagnostic and treatment concepts. Currently， comprehensive treatment， mainly surgery， is used for treatment， but there is still controversy over the selection of clinical treatment strategies. This article provides a detailed discussion on surgical methods and prognosis， in order to provide a reference for clinical treatment options.

Debates persist regarding the efficacy and safety of azvudine, particularly its real-world outcomes. This study involved patients aged ≥60 years who were admitted to 25 hospitals in mainland China with confirmed SARS-CoV-2 infection between December 1, 2022, and February 28, 2023. Efficacy outcomes were all-cause mortality during hospitalization, the proportion of patients discharged with recovery, time to nucleic acid-negative conversion (T _NANC), time to symptom improvement (T _SI), and time of hospital stay (T _HS). Safety was also assessed. Among the 5884 participants identified, 1999 received azvudine, and 1999 matched controls were included after exclusion and propensity score matching. Azvudine recipients exhibited lower all-cause mortality compared with controls in the overall population (13.3% vs. 17.1%, RR, 0.78; 95% CI, 0.67-0.90; P = 0.001) and in the severe subgroup (25.7% vs. 33.7%; RR, 0.76; 95% CI, 0.66-0.88; P < 0.001). A higher proportion of patients discharged with recovery, and a shorter T _NANC were associated with azvudine recipients, especially in the severe subgroup. The incidence of adverse events in azvudine recipients was comparable to that in the control group (2.3% vs. 1.7%, P = 0.170). In conclusion, azvudine showed efficacy and safety in older patients hospitalized with COVID-19 during the SARS-CoV-2 omicron wave in China.

High-performance phototheranostics with combined photothermal therapy and photoacoustic imaging have been considered promising approaches for efficient cancer diagnosis and treatment. However, developing phototheranostic materials with efficient photothermal conversion efficiency (PCE), especially over the second near-infrared window (NIR-II, 1000-1700 nm), remains challenging. Herein, we report an ultraefficient NIR-II-activated nanomedicine with phototheranostic and vaccination capability for highly efficient in vivo tumor elimination and metastasis inhibition. The NIR-II nanomedicine of a semiconducting biradical oligomer with a motor-flexible design was demonstrated with a record-breaking PCE of 87% upon NIR-II excitation. This nanomedicine inherently features extraordinary photothermal stability, good biocompatibility, and excellent photoacoustic performance, contributing to high-contrast photoacoustic imaging in living mice and high-performance photothermal elimination of tumors. Moreover, a whole-cell vaccine based on a NIR-II nanomedicine with NIR-II-activated performance was further designed to remotely activate the antitumor immunologic memory and effectively inhibit tumor occurrence and metastasis in vivo, with good biosafety. Thus, this work paves a new avenue for designing NIR-II active semiconducting biradical materials as a promising theranostics platform and further promotes the development of NIR-II nanomedicine for personalized cancer treatment.

Acute ischemic stroke (AIS) is a cerebrovascular disease characterized by high morbidity, disability, and mortality, posing a significant threat to human health. Endovascular treatment has now been established as a key method for AIS management, in which stent retrievers that can mechanically remove blood clots play a key role in this technique. In recent years, stent retrievers have evolved in complexity and functionality to improve the ability of clot removing and surgical safety. However, the present instruments still have limitations on treatment efficiency, vascular adaptability, and operational precision, posing an urgent need for innovation in the design of stent retrievers. This paper systematically reviewed the structural features and working principles of AIS stent retrievers from the perspective of efficacy evaluation metrics, historical development, recent advancements in stent retrieval technology, and future prospects.

Objective To compare the intestinal injury induced by different intensities of waveshock in rats exposed to extremely cold environment and to preliminarily explore the characteristics of the injury.Methods Sixty healthy male SD rats(2 months old,weighing 200～250 g)were randomly divided into 6 groups(n=10):blank control group,low-temperature control group,5.0 MPa shock control group,and low-temperature+4.0,4.5 and 5.0 MPa shock groups.The rats in the experimental groups were pre-treated in a-10℃low-temperature environment for 30 min and then subjected to intestinal injury by using BST-I biological shock tube with different driving pressures.At 3,8,and 24 h after injury,the serum levels of IL-6,TNF-α,intestinal fatty acid binding protein(I-FABP),and diamine oxidase(DAO)were detected,and the survival of rats within 24 h was recorded.At 24 h after injury,the rats were anesthetized and dissected,the characteristics of intestinal injury were observed,and pathological examination was performed.The differences of intestinal injury were compared among the 6 groups to explore the characteristics of intestinal injuries after different intensities of shockwave in rats after exposure to extremely cold environment.Results Compared with the blank control group,the other 5 groups exhibited different severities of intestinal injury,and the rats in the low-temperature+different shock groups were more prone to intestinal edema and trauma.The mortality rate was significantly increased in the low-temperature+5.0 MPa shock group(P<0.05).Pathological and serological studies found that dual effects of very cold environment and blast injury resulted in intestinal mucosal hemorrhage,edema,and disintegration of lamina propria in the experimental rats.The indicators of intestinal mucosal injury and intestinal inflammatory factors were also significantly increased when compared with the blank control group,and significant differences were among the groups with increment of shock intensity(P<0.05).Conclusion Exposure to very cold environment combined with abdominal blast injury increases mortality rate in rats,manifested by elevated serological indicators and intestinal inflammatory factors,as well as varying severities of intestinal wall edema and submucosal bleeding.Furthermore,the severity of the injury is positively related to the impact intensity,with worsened as the impact intensity increasing.

AIM:To summarize the clinical features and prognostic factors of patients with open ocular trauma in northwest China, and to explore the application of ocular trauma score(OTS)in open ocular trauma.METHODS:The clinical data of 91 patients(91 eyes)with open ocular trauma admitted to Xijing Hospital from June 2021 to June 2023 were retrospectively analyzed. The correlation analysis of visual acuity prognosis was carried out by age, treatment time, initial visual acuity, trauma zone and other factors, and the relationship between different OTS and prognostic visual acuity was discussed.RESULTS:Univariate analysis showed that age(0-20 years), treatment time(<24 h), initial visual acuity, trauma zone, trauma type(penetrating injury), anterior chamber hematoma, vitreous hematoma were correlated with prognostic visual acuity(all P<0.1); multivariate Logistic regression analysis showed that initial visual acuity and treatment time(<24 h)were risk factors(both P<0.05). There was a significant correlation between different OTS and prognostic visual acuity(rs=0.639,P<0.001).CONCLUSION:Patients with open ocular trauma should be diagnosed and treated as early as possible. The main factors influencing the visual prognosis are age, treatment time, initial visual acuity, trauma zone, trauma type, anterior chamber hematoma and vitreous hematoma. OTS has good application value in visual acuity evaluation of open ocular trauma prognosis.

Objective To investigate the expression of cysteine-rich intestinal protein 1(CRIP1),STIP1 ho-mology and U-box protein 1(STUB1)in cancer tissues of patients with hepatocellular carcinoma and their clinical prognostic significance.Methods From February 2018 to February 2020,112 patients with hepatocel-lular carcinoma were selected as the study objects.The expression of CRIP1 and STUB1 in cancer tissues and adjacent tissues of patients with hepatocellular carcinoma was detected by immunohistochemistry.To analyze the relationship between the expression of CRIP1 and STUB1 and their clinicopathological features in hepato-cellular carcinoma patients.Kaplan-Meier survival analysis of the effects of CRIP1 and STUB1 expression on the prognosis of patients with hepatocellular carcinoma.COX regression analysis was performed to analyze the prognostic factors of hepatocellular carcinoma.Results The positive rate of CRIP1 in cancer tissues of pa-tients with hepatocellular carcinoma was 62.50％(70/112),which was significantly higher than that in adja-cent tissues[7.14％(8/112)],the difference was statistically significant(x2=76.652,P＜0.05).The positive rate of STUB1 in cancer tissues of patients with hepatocellular carcinoma was 26.23％(32/112),significantly lower than that in adjacent tissues[82.14％(92/112)],and the difference was statistically significant(x2=73.284,P＜0.05).The expression of CRIP1 was negatively correlated with STUB1 in cancer tissues(r=-0.678,P＜0.001).There were significant differences in the positive rates of CRIP1 and STUB1 in hepato-cellular carcinoma patients with different TNM stages,histological grades and maximum tumor diameter(P＜0.05).The 3-year cumulative survival rate of CRIP1 positive group was significantly lower than that of CRIP1 negative group,with statistical significance(Log-rank x2=29.601,P＜0.001).The 3-year cumulative survival rate of STUB1 negative group was significantly lower than that of STUB1 positive group,with statistical sig-nificance(Log-rank x2=13.590,P＜0.001).TNM stage Ⅱ-Ⅲ,histological grade Ⅲ,maximum tumor diam-eter＞5 cm,CRIP1 positive and STUB1 negative were independent risk factors for prognosis of hepatocellular carcinoma patients.Conclusion CRIP1 expression is up-regulated and STUB1 expression is down-regulated in hepatocellular carcinoma tissues.The prognosis of patients with hepatocellular carcinoma can be evaluated clinically based on the expression of CRIP1 and STUB1 in hepatocellular carcinoma tissues.

Osteoarthritis (OA) is a chronic degenerative joint disease whose main characteristic is the destruction of articular cartilage, causing pain and disability in patients and seriously affecting their quality of life. OA can be induced by a variety of causes, and pathological changes in articular cartilage are considered to be one of the key driving factors for the occurrence of OA. High mobility group box-1 protein (HMGB1), as a non-histone protein in eukaryotic cells, can participate in regulating the inflammation and apoptosis process of OA chondrocytes, thus leading to the occurrence of OA. This article reviews the research on the mechanism of HMGB1 in OA chondrocytes, with a view to providing new ideas for the clinical prevention and treatment of OA.
