Objective: To explore the clinical significance of transcription factor Sp1 expression in hepatocellular carcinoma (HCC) and association between Sp1 expression and survival in HCC patients. Methods:With the use of immunoreactivity, Sp1 expres-sion and its correlation with other clinicopathological characteristics were examined in a tissue microarray that contains samples from 98 HCC patients. Results:HCC tissues expressed markedly higher levels of Sp1 than did adjacent normal liver tissues. Sp1 expression was closely associated with microvascular invasion, which suggests that HCC with more microvascular invasion is prone to have in-creased Sp1 expression. Overexpression of Sp1 correlates with significantly shorter overall survival and higher recurrence rates in HCC patients after curative resection. Conclusion:Transcription factor Sp1 may be an independent prognostic factor for both overall surviv-al and cumulative recurrence rate.

Objective To explore the effects of delayed mild hypothermia (MHT) in different time windows on the expressions of Bcl-2, Bax and Caspase-3 in brain tissue of model rats with traumatic brain injury (TBI). Methods Thirty-six clean adult male SD rats were randomly divided into NT group (normal temperature), MHT 15 min group, MHT 2 h group and MHT 4 h group. TBI rat model was established by electronical controlled cortical injury device. The rats in the NT group were treated with normothermia (37℃) and the rats in the three hypothermia groups were implemented with low temperature (33.0±1.0)℃at 15 min, 2 h and 4 h for 6 h respectively after establishment of TBI model. The modified neurological senerity scores (mNSS), morphological changes in hippocampal CA1 areas, immunohistochemical staining and Western blot assay for Bcl-2, Bax and Caspase-3 were compared 3 days after TBI between the four groups. Results The neurological behavioral deficits were found in each group. Compared with the NT group, the mNSS were decreased in the three hypothermia groups (P<0.01). The results of HE staining showed that the structure of neurons was regular and arranged neatly, and the number of neurons decreased with alleviated nuclear fragmentation and dissolution in hypothermia groups. Compared with the NT group, the expression of Bcl-2 was upregulated, and the expressions of Bax and Caspase-3 were downregulated in three hypothermia groups (P<0.05). The above experimental results were superior in MHT15 min group to MHT 2 h group, and the therapeutic effect in MHT 2 h group was similar to MHT 4 h group. Conclusion The proper delayed mild hypothermia treatment could inhibit neuronal apoptosis and alleviate brain damage.

Objective To analyze the clinical effects of thrombolytic therapy in patients with ischemic in-hos-pital stroke (IHS). Methods The clinical data were collected from patients with ischemic IHS in the last five years. The patients were divided into thrombolysis group and non-thrombolysis group, according to the use of recombinant tissue plasminogen activator (r-tPA) treatment. The clinical outcomes were measured by the modified Rankin scale (mRS) at discharge. Results There were a total of 121 patients in this study. There were 6 patients in thrombolysis group and 115 patients in the non-thrombolysis group, respectively. Six patients (100%) in the thrombolysis group achieved favor-able outcomes (mRS 0~2) at discharge whereas only 42 patients (36.5%) in the non-thrombolysis group achieved fa-vourable outcomes. The rate of favorable outcomes was significantly higher in the thrombolysis group than in the non-thrombolysis group (P<0.05). Conclusions R-tPA thrombolytic therapy can improve the prognosis of patients with ischemic IHS.

Objective:To analyze independent influencing factors of surgical textbook outcome (TO) in patients with gallbladder carcinoma, and to establish a nomogram for predicting TO and evaluated the predictive ability.Methods:Patients with gallbladder carcinoma who underwent surgery in Department of Hepatobiliary and Pancreatic Surgery at Dongfang Hospital Affiliated to Shanghai Tongji University and Department of Biliary Tract Surgery Ⅰ, Third Affiliated Hospital of Naval Medical University (Shanghai Eastern Hepatobiliary Surgery Hospital) from January 2013 to December 2018 were included and the clinical features were retrospectively analyzed. A total of 232 patients were included, including 114 males and 118 females, aged (61.0±9.8) years. According to whether TO reached or not, they were divided into TO group ( n=86) and non-TO group ( n=146). Univariate and multivariate logistic regression were used to analyze the independent influencing factors of TO. The predictive nomogram model of TO was constructed. The receiver operating characteristic (ROC) curve was drawn to evaluate the predictive ability of the model, and the consistency of the predictive model was evaluated by the consistency curve graph and the Hosmer-Lemeshow test. Results:The 1-year and 3-years cumulative survival rates of patients with gallbladder carcinoma in the TO group (86.0% and 62.8%) were better than those in the non-TO group (46.6% and 27.3%), and the difference was statistically significant (χ 2=60.74, P<0.001). In multivariate analysis, higher T stage ( OR=0.16, 95% CI: 0.03-0.79, P<0.001) and cervical gallbladder cancer ( OR=0.14, 95% CI: 0.02-0.94, P=0.004) had the greatest negative association with a TO, and the higher the degree of tumor differentiation ( OR=7.08, 95% CI: 1.34-37.56, P=0.001), the easier it is to achieve TO. The ROC curve showed that the area under the curve of the predictive model was 0.84 (95% CI: 0.79-0.90), suggesting that the model had good predictive performance. A nomogram to assess the probability of TO was developed and had good accuracy in both the consistency curve and Hosmer-Lemeshow test (χ 2=5.77, P=0.673). Conclusion:Tumor T stage, tumor differentiation degree and tumor location are independent influencing factors for achieving TO in patients with gallbladder carcinoma after surgery. The nomogram model constructed according to the above conclusions could accurately predict the probability of reaching TO.

Animal experiments play an important role in the process of biomedical research, and is a necessary way to transform basic medicine into clinical medicine. The standardization of animal experimental studies and reports determines the reliability and reproducibility of research results, and is also the key to transforming the results of animal experiments into clinical trials. In view of how to design and implement animal experiments, write animal experiment reports, and publish relevant academic papers in a more standardized way, LACM (Laboratory Animal and Comparative Medicine) has launched a new column of comparative medical research and reporting standards from 2023, focusing on the introduction and interpretation of international general norms related to laboratory animal and comparative medicine, such as ARRIVE 2.0 guidelines (Animal Research: Reporting of In Vivo Experiments). This article focuses on the development and application, basic content and priority of ARRIVE 2.0, as well as the scheme of implementing ARRIVE 2.0 guidelines in international biomedical journals, and explains the current situation and future plans of LACM following ARRIVE 2.0 guidelines. The research and report of animal experimental medicine following the ARRIVE 2.0 guidelines and other international norms is one of the important driving forces to promote the high-quality development of experimental animal science and biomedicine in China, and also a powerful means to implement the 3R principle and improve the welfare of laboratory animals. Through this article, we hope the majority of scientific researchers and editors will attach great importance and actively implement these international standards.
