Local anesthetics (LAs), such as articaine (AT), exhibit limited efficacy in inflammatory environments, which constitutes a significant limitation in their clinical application within oral medicine. In our prior research, we developed AT-17, which demonstrated effective properties in chronic inflammatory conditions and appears to function as a novel oral LA that could address this challenge. In the present study, we further elucidated the beneficial effects of AT-17 in acute inflammation, particularly in oral acute inflammation, where mitochondrial-related apoptosis played a crucial role. Our findings indicated that AT-17 effectively inhibited lipopolysaccharide (LPS)-induced nerve cell apoptosis by ameliorating mitochondrial dysfunction in vitro. This process involved the inhibition of mitochondrial reactive oxygen species (mtROS) production and the subsequent activation of the NRF2 pathway. Most notably, improvements in mitochondria-related apoptosis were key contributors to AT-17's inhibition of voltage-gated sodium channels. Additionally, AT-17 was shown to reduce mtROS production in nerve cells through the Na⁺/NCLX/ETC signaling axis. In conclusion, we have developed a novel local anesthetic that exhibits pronounced anesthetic functionality under inflammatory conditions by enhancing mitochondria-related apoptosis. This advancement holds considerable promise for future drug development and deepening our understanding of the underlying mechanisms of action.

The quality of traditional Chinese medicine (TCM) prescriptions (TCMPs) is critical to clinical efficacy; however, evaluating their consistency and identifying sources of variability remain challenging. This study proposes an integrated strategy to assess the quality of 100 widely sold TCMPs. A "one-for-all" chromatographic method was employed to analyze 645 sample batches. This large-scale data collection enabled statistical evaluations, such as hierarchical cluster analysis (HCA) and similarity heatmap, to identify quality inconsistencies. The introduction of a TCM-specific mass spectrometry (MS) database allowed for rapid, automated annotation of chemicals across 100 prescriptions and facilitated the tracing of raw material sources. Results indicate that 19% of prescriptions exhibited chemical inconsistencies, which are associated with high market value, low pricing, and substantial price disparities. The MS database allowed rapid annotation of 761 and 673 compounds in positive and negative modes, respectively, in 100 TCMPs, with 73 prescriptions reported for the first time. The tracing efforts succeeded in identifying >40% of the raw material sources for 51 prescriptions. P93 (Yinianjin (YNJ)) is a case in which the chromatographic profiles from three manufacturers displayed inconsistencies. Analysis using the database traced divergent peaks to Rhei Radix et R hizoma (RRER). Verification with self-prepared samples confirmed that manufacturers utilized three distinct botanical sources. This integrated strategy provides a scalable framework for quality control in TCMPs.

Objective To investigate the role of transcranial magnetic stimulation(TMS)in the modulation of abnormal functional status and damage characteristics of key brain regions in adult patients with anisometropic amblyopia via the resting-state functional magnetic resonance imaging(rs-fMRI)technique.Methods Single(left)eyes of 20 adult refractive amblyopia patients were included in this study and randomly divided into a surgical group[Implantable Collamer Lens(ICL)surgery]and a TMS combined group(TMS treatment on top of the surgical group),with 10 patients in each group.In both groups,the visual a-cuity of patients was examined before and after treatment via international standard visual acuity charts to evaluate the therapeu-tic effect.Moreover,patients in both groups underwent an fMRI examination once before and after treatment,and local coher-ence(ReHo),amplitude at low frequency(ALFF),and ratio amplitude at low frequency(fALFF)algorithms were used to char-acterize the functional state and response characteristics of the brain regions in the acquired f MRI images.Results Compared with that before treatment,the visual acuity of patients in both groups significantly improved after treatment and was signifi-cantly greater than the pretreatment corrected visual acuity(P＜0.05).Compared with that in the two groups after treatment,the improvement in visual acuity in the TMS combined group was greater than that in the surgical group(P＜0.05).There was no difference in the ReHo or fALFF values before and after treatment between the TMS combined group and surgical group.Compared with those before treatment,the ipsilateral frontal ALFF values were increased in the surgical group after treatment,and the ipsilateral cerebellar ALFF values were decreased in the TMS combined group.Compared with those in the surgical group,the ipsilateral frontal lobe and superior frontal gyrus ReHo values decreased,the contralateral temporal lobe and superior temporal gyrus ALFF values decreased,and the contralateral occipital lobe and cuneiform lobe fALFF values increased after treatment in the TMS combined group(all P＜0.05).Conclusion The improvement in spontaneous brain activity in pa-tients with anisometropic amblyopia in the surgical group and in the TMS combined group was significant.ICL implantation may act by activating the ipsilateral frontal lobe,ICL implantation in combination with TMS may act by improving cerebellar func-tion,increasing the excitability of the contralateral occipital and cuneate lobes,modulating neuronal activity in the adjacent cor-tex of the occipital lobe and in the other visually related cortices(ipsilateral frontal and contralateral temporal lobes),and correc-ting the difference in excitability between the two eyes of the patients.and correcting the excitability differences between the pa-tient's two eyes.

BackgroundThe existing tools in China for assessing psychiatric nurses' knowledge， attitude and practice towards the use of protective restraint do not sufficiently consider the specialty in psychiatric practice， and the scale items are somewhat cumbersome to use， which together restrict their further promotion and application. Accordingly， there is an urgent need for developing a more scientific assessment tool. ObjectiveTo construct a scale for assessing psychiatric nurses' knowledge， attitude and practice towards the use of protective restraint and to verify its reliability and validity， so as to provide a generic tool for the assessment. MethodsBased on the theoretical framework of the knowledge-attitude-practice model， the preliminary scale was formed through systematic literature review， qualitative interview and Delphi method. From July to December 2021， a stratified sampling was utilized to select 729 psychiatric nurses from tertiary， secondary and primary （including unclassified medical institutions and grassroots hospitals） psychiatric hospitals in Guangdong Province. The formal scale was developed through item analysis， exploratory factor analysis and confirmatory factor analysis. The validity of the scale was evaluated by content validity and structure validity， and the reliability was verified by procedures including Cronbach's α coefficient， test-retest reliability， and split-half reliability. ResultsA total of 12 items of three dimensions （knowledge， attitude， practice） were included in the scale for assessing psychiatric nurses' knowledge， attitude and practice towards the use of protective restraint. The scale-level content validity index （S-CVI） was 0.941， and the item-level content validity index （I-CVI） ranged from 0.812 to 1.000. Exploratory factor analysis extracted three common factors， and the cumulative variance contribution rate was 62.948%. The confirmatory factor yielded adequate fit. Cronbach's α coefficient was found to be 0.887 for the scale， 0.819 for knowledge dimension， 0.842 for attitude dimension， and 0.831 for practice dimension. The split-half reliability and test-retest reliability for the scale were 0.712 and 0.922， respectively. ConclusionThe scale shows satisfactory reliability and validity， which can be used to assess psychiatric nurses' knowledge， attitude and practice towards the use of protective restraint. ［Funded by Guangdong Clinical Teaching Base Teaching Reform Research Project （number， 2021JD119）］

Cancer is the leading cause of death worldwide. Drugs play a pivotal role in cancer treatment, but the complex biological processes of cancer cells seriously limit the efficacy of various anticancer drugs. Autophagy, a self-degradative system that maintains cellular homeostasis, universally operates under normal and stress conditions in cancer cells. The roles of autophagy in cancer treatment are still controversial because both stimulation and inhibition of autophagy have been reported to enhance the effects of anticancer drugs. Thus, the important question arises as to whether we should try to strengthen or suppress autophagy during cancer therapy. Currently, autophagy can be divided into four main forms according to its different functions during cancer treatment: cytoprotective (cell survival), cytotoxic (cell death), cytostatic (growth arrest), and nonprotective (no contribution to cell death or survival). In addition, various cell death modes, such as apoptosis, necrosis, ferroptosis, senescence, and mitotic catastrophe, all contribute to the anticancer effects of drugs. The interaction between autophagy and these cell death modes is complex and can lead to anticancer drugs having different or even completely opposite effects on treatment. Therefore, it is important to understand the underlying contexts in which autophagy inhibition or activation will be beneficial or detrimental. That is, appropriate therapeutic strategies should be adopted in light of the different functions of autophagy. This review provides an overview of recent insights into the evolving relationship between autophagy and cancer treatment.

ObjectiveBy comparing the difference of volatile components of the decoction pieces before and after being processed by braising method of Jianchangbang and steaming method included in the 2020 edition of Chinese Pharmacopoeia， the influence of processing methods on the flavor formation of Polygoni Multiflori Radix （PMR） was compared. MethodHeadspace-gas chromatography-mass spectrometry （HS-GC-MS） was used to detect the volatile components of 30 batches of PMR samples from 3 origins with 3 processing methods. The GC was performed under programmed temperature （starting temperature of 40 ℃， rising to 150 ℃ at 5 ℃·min^-1， and then rising to 195 ℃ at 10 ℃·min^-1） with high purity helium as carrier gas and the split ratio of 10∶1. Mass spectrometry conditions were electron impact ion source （EI） and the detection range of m/z 50-650， the peak area normalization method was used to calculate the relative mass fraction of each component. The chromaticity values of different processed products were measured by a precision colorimeter， the relationship between chromaticity values and relative contents of volatile components was investigated by OriginPro 2021， principal component analysis （PCA） and orthogonal partial least squares-discriminant analysis （OPLS-DA） were performed on the sample data by SIMCA14.1. The differential components of different processed products of PMR were screened according to the principle of variable importance in the projection （VIP） value>1.5， and the material basis of different odor formation of PMR and its processed products was explored. ResultA total of 59 volatile components were identified， among which 34 were raw products， 33 were braised products， and 27 were steamed products. PCA and OPLS-DA results showed that there were significant differences between the three， but there was no significant difference between samples from different origins of the same processing method. Color parameters of a^*， b^*， E^*ab had no significant correlation with contents of volatile components， while L^* was negatively correlated with contents of 2-methyl-2-butenal， 2-methyltetrahydrofuran-3-one and 2，3-dihydro-3，5-dihydroxy-6-methyl-4（H）-pyran-4-one （P<0.05）. The contents of pungent odor components such as caproic acid， nonanoic acid and synthetic camphor decreased after processing， while the contents of sweet flavor components such as 2-methyl-2-butenal， furfural and 5-hydroxymethylfurfural increased after processing， and the contents of furfural， 5-methyl-2-furanmethanol， 5-hydroxymethylfurfural and other aroma components in the braised products were significantly higher than that in the steamed products. ConclusionHS-GC-MS can quickly identify the volatile substance basis that causes the different odors of PMR and its processed products. The effect of processing methods on the odor is greater than that of origin. There is a significant correlation between the color parameter of L^* and contents of volatile components， the "raw" taste of PMR may be related to volatile components such as caproic acid， pelargonic acid and synthetic camphor， the "flavor" after processing may be related to the increase of the contents of 2-methyl-2-butenal， furfural， 5-hydroxymethylfurfural， methyl maltol and furfuryl alcohol.

Reflex tests are ordered when a particular test result indicates that additional testing should be performed according to the guidelines or the feedback process formulated by clinical consultation. The application scope of the reflex tests involves various subspecialties of laboratory medicine. The clinical application needs the support of qualified laboratory doctors, comprehensive information and financial system, clinical guidelines, and so on. Active application of reflex tests can promote the standardization of evidence-based medicine in clinical practice, save medical resources, and shorten the diagnosis and treatment time of patients.

Objective:To investigate the clinical characteristics and change trend of patients with perianal lesions before or after Crohn′s disease (CD) diagnosed.Methods:From January 2008 to September 2018, at The Tenth People′s Hospital Affiliated to Tongji University, the clinical data of 747 hospitalized CD patients were retrospectively collected, 293 patients were PCD patients. The clinical characteristics of PCD patients before or after CD diagnosed were analyzed and the change trend was followed. T test, Mann-Whitney U test, and Chi-square test were performed for statistical analysis. Multivariate logistic regression analysis was used to analyze factors associated with perianal lesions onset time. Spearman correlation analysis was used to analyze the change trend of clinical characteristics. Results:Before CD diagnosis, 86.3% (253/293) PCD patients had perianal lesions. The median follow-up time (range) was 72 months (36 to 108 months). Compared with the patients presented with perianal lesions after CD diagnosis, the onset age of patients with perianal lesions before CD diagnosis was younger ((36.0±12.6) years vs. (24.2±10.2) years), and the rates of male (62.5%, 25/40 vs. 77.9%, 197/253), non-structuring and non-penetrating type (32.5%, 13/40 vs. 56.9%, 144/253) and perianal surgery (55.0%, 22/40 vs.76.7%, 194/253) were high, but low rate of abdominal surgery (37.5%, 15/40 vs. 13.0%, 33/253), and the differences were statistically significant ( t=2.630, χ2=4.442, 8.379, 8.379 and 15.081; all P<0.05). The results of logistic multivariate analysis showed that before CD diagnosis, non-structuring and non-penetrating type was more common than structuring type (odds ratio ( OR)=0.447, 95% confidence interval ( CI) 0.207 to 0.962, P=0.039) and penetrating type ( OR=0.264, 95% CI 0.089 to 0.780, P=0.016). The short disease duration of CD ( OR=0.981, 95% CI 0.968 to 0.995, P=0.008), structuring type ( OR=2.239, 95% CI 1.040 to 4.822, P=0.039) and penetrating type ( OR=3.788, 95% CI 1.281 to 11.198, P=0.016) were the risk factors of perianal lesions after CD diagnosed. The number of PCD patients ( r=0.964, P<0.01) and the proportion of biological agents ( r=0.879, P<0.01) increased with years, while PCD duration ( r=-0.828, P<0.01) and the rate of abdominal surgery significantly decreased with years ( r=-0.882, P<0.01). The proportion of biological agents was negatively correlated with the rate of abdominal surgery ( r=-0.770, P=0.006). Conclusions:The perianal lesions should be closely monitored in adult CD patients with short disease duration, structuring type and penetrating type for early diagnosis and treatment. Biological agents can improve the clinical outcomes of PCD.
