ObjectiveTo investigate whether there are differences in the efficacy of Gegen Qinliantang with different contents of Puerariae Lobatae Radix on the acute enteritis （AE） model mice and provide a scientific basis for the interpretation of Gegen Qinliantang in the treatment of "Xie Re Li". MethodsA total of 112 male BALB/c mice were randomly divided into a blank group，model group，single Puerariae Lobatae Radix group，non-Puerariae Lobatae Radix group，regular dose Gegen Qinliantang group （regular dose group），half-dose Puerariae Lobatae Radix group，and doubled-dose Puerariae Lobatae Radix group， with 16 mice in each group. Hematoxylin-eosin （HE） staining was used to observe the pathological changes of the colon tissue. Western blot was employed to detect the expression of ZO-1 （a protein in the tight junction） and Occludin in the colon tissue， as well as the changes of tumor necrosis factor-α （TNF-α） and interleukin-1β （IL-1β）. ResultsCompared with the blank group，the DAI scores of the mice in the model group were significantly higher （P<0.05），and the histopathological sections of their colon tissues showed mucosal damage，glandular atrophy，disordered arrangement，and a large number of inflammatory cells infiltration，and the expression of ZO-1 and Occludin proteins in their colon tissues was significantly down-regulated （P<0.05，P<0.01）. The expression of inflammatory factors TNF-α and IL-1β was significantly up-regulated （P<0.05，P<0.01）. Compared with the model group，the DAI scores of mice in all dosing groups decreased significantly （P<0.05），with the most significant effect in the regular dose group. After 7 d of drug administration，the regular dose group had the best impact on the repair of colonic mucosa in the AE mouse model. The regular dose group significantly down-regulated the expression of TNF-α （P<0.05） and significantly up-regulated the expression of ZO-1 protein （P<0.05）. The doubled-dose Puerariae Lobatae Radix group significantly down-regulated the expression of IL-1β protein （P<0.01），and there was no significant difference between all dosing groups and the model group in terms of the expression of Occludin protein. After 14 d of drug administration，the best effect on the repair of colonic mucosa in the AE mouse model was observed in the doubled dose Puerariae Lobatae Radix group. All groups except the non-Puerariae Lobatae Radix group significantly down-regulated the expression of TNF-α （P<0.01）. Meanwhile，the regular dose group and doubled-dose Puerariae Lobatae Radix group significantly elevated the expression level of Occludin protein （P<0.01）. The doubled-dose Puerariae Lobatae Radix group also significantly inhibited the expression of IL-1β protein （P<0.05） and up-regulated ZO-1 protein expression （P<0.05）. ConclusionGegen Qinliantang can reduce the pathological damage of colon tissue， protect the barrier function and structure of intestinal epithelial cells， and reduce the expression of inflammatory factors， so as to achieve the therapeutic effect of AE model mice. When comparing the therapeutic efficacy of Gegen Qinliantang containing different Gegen contents， Gegen Qinliantang with the proportion of the original formula of Zhongjing was the most effective in AE model mice.

The deficiency of fingers due to various reasons leads to a certain degree of loss of full or part hand functions. Physical and mental health of patients are seriously affected, and patients have varying degrees of reduced quality of life. Prosthesis fingers play an important role in completing the body shape and enhancing patients’ self-confidence and self-esteem. However, how to make prosthesis fingers perform coordinated movements and restore complete functions is a crucial problem that urgently needs to be solved. This paper reviews the methods of brain-computer interface controlled fine finger movements and elaborates on the origin, current situation, and advancements of the development of this technology, laying a foundation for subsequent research, with the expectation of helping patients solve the problems arising from the insufficiency or absence of finger functions.

ObjectiveTo investigate the modifiable areal unit problem （MAUP） in the spatial pattern of Pseudostellaria heterophylla production regions and reveal the impact of statistical scales on the spatial distribution characteristics of this medicinal plant species. MethodsUsing multi-source data （literature records， field surveys， and statistical data）， we systematically analyzed the spatial patterns across three administrative levels （provincial， prefectural， and county scales）. Spatial autocorrelation （Moran's I） analysis， high-low clustering （Getis-Ord General G）， and hot/cold spot analysis （Getis-Ord Gi*） were employed. ResultsThe literature-based analysis showed that the production regions of P. heterophylla presented random distribution on the provincial scale and significant aggregation on the prefectural scale. The field survey data showed that the production regions displayed random distribution on the provincial scale but significant aggregation on both prefectural and county scales. The statistical data revealed that the production regions lacked spatial autocorrelation on the provincial scale but demonstrated significant aggregation on prefectural and county scales. ConclusionMAUP effects have substantive implications for understanding and decision-making in the arrangement of medicinal plant production regions. The county scale proves to be the most sensitive and explanatory level for analyzing the spatial pattern of P. heterophylla production regions， providing a critical foundation for habitat modeling， suitability evaluation， and ecological cultivation planning of medicinal plants.

Objective To study the correlation between traditional Chinese medicine(TCM)constitution and pathogenic factors in patients with ankylosing spondylitis(AS).Methods One hundred patients of AS and their family members who had medical consultation in the Fifth Hospital of Xi'an(i.e.,Shaanxi Hospital of Integrated Traditional Chinese and Western Medicine)in August 2019 and September 2020 were selected as the study subjects.The guidelines of Classification and Determination of Traditional Chinese Medicine Constitution issued by the China Association of Chinese Medicine were adopted to determine the traditional Chinese medicine(TCM)constitution types of the study subjects.The sociodemographic information,living habits,clinical symptoms,and TCM constitution types of the AS patients and their family members were collected by means of questionnaires and clinical investigations,and then the pathogenic factors of the patients with AS were investigated.The binomial Logistic regression model was used to analyze the correlation between TCM constitution types and pathogenic factors in patients with AS.Results(1)Among the 100 AS patients,the majority of them had the biased constitutions,and the biased constitutions with the occurrence frequency in descending order were yang deficiency constitution,qi deficiency constitution,and damp-heat constitution,which accounted for 33.00%,14.00%,and 18.00%,respectively.(2)The prevalence rates of AS in the first-,second-,and third-degree relatives of AS patients were 56.25%,40.00%and 25.00%,respectively.For the positive rates of human leukocyte antigen B27(HLA-B27)in AS patients and their family members,HLA-B27 in AS patients was all positive,while the positive rates of HLA-B27 in the first-,second-,and third-degree relatives of AS patients were 44.31%,30.67%and 15.63%,respectively.(3)The results of regression analysis showed that the disease duration of AS patients was significantly correlated with qi deficiency constitution,the grading of sacroiliac arthritis was correlated with qi stagnation constitution,and age was correlated with blood stasis constitution(P＜0.05 or P＜0.01).The results indicated that disease duration and age were the important factors affecting the constitution types of AS patients,and disease duration was closely related to qi deficiency while age was closely related to blood stasis.Conclusion AS is a highly hereditary autoimmune disease,and its onset is associated with HLA-B27.Yang deficiency is the basic constitution type of AS,and damp-heat constitution is the main constitution type in the progression of AS(especially in the active stage of the disease).The prolongation of the disease will exacerbate the illness condition of AS and then the manifestations of qi deficiency will be more obvious.

Objective To explore the clinical efficacy of fluoxetine hydrochloride combined with estradiol valerate in the treatment of perimenopausal depression patients.Methods A total of 120 patients with perimenopausal depressive disorder admitted to Shaoxing 7th People's Hospital from January 2021 to January 2024 were selected as the study subjects.According to random number table method,the patients were divided into control group and observation group,60 cases in each group.The control group patients received estradiol valerate treatment,while the observation group patients additionally received fluoxetine hydrochloride.All patients were treated continuously for 8 weeks.At 4 weeks and 8 weeks of treatment,Hamilton depression scale (HAMD) was used to compare depression severity before and after treatment.Modified Kupperman index (KMI) was used to compare severity of menopausal symptoms before and after treatment.Changes in sex hormone levels,including follicle stimulating hormone (FSH),luteinizing hormone (LH),and estradiol (E2) were measured and compared before and after treatment.The correlation between depression severity and sex hormone levels and the severity of menopausal symptoms were evaluated using Spearman correlation analysis.Results At 4 weeks and 8 weeks of treatment,HAMD and KMI scores of observation group were significantly lower than before treatment,and lower than those of control group (P<0.05).The FSH and LH levels in both groups were significantly lower than before treatment,while E2 levels were significantly higher than before treatment (P<0.05).Spearman correlation analysis showed that HAMD score were positively correlated with KMI score,FSH level,and LH level,and negatively correlated with E2 level.Conclusion Compared with the use of estradiol valerate alone,the combination of fluoxetine hydrochloride and estradiol valerate is more effective in alleviating the severity of depression in patients with perimenopausal depression.Moreover,the severity of depression is closely related to the severity of symptoms and sex hormone levels,suggesting that this combined treatment regimen has broader applicability for patients with perimenopausal depression.

Purpose::Cerebral edema (CE) is the main secondary injury following traumatic brain injury (TBI) caused by road traffic accidents (RTAs). It is challenging to be predicted timely. In this study, we aimed to develop a prediction model for CE by identifying its risk factors and comparing the timing of edema occurrence in TBI patients with varying levels of injuries.Methods::This case-control study included 218 patients with TBI caused by RTAs. The cohort was divided into CE and non-CE groups, according to CT results within 7 days. Demographic data, imaging data, and clinical data were collected and analyzed. Quantitative variables that follow normal distribution were presented as mean ± standard deviation, those that do not follow normal distribution were presented as median (Q 1, Q 3). Categorical variables were expressed as percentages. The Chi-square test and logistic regression analysis were used to identify risk factors for CE. Logistic curve fitting was performed to predict the time to secondary CE in TBI patients with different levels of injuries. The efficacy of the model was evaluated using the receiver operator characteristic curve. Results::According to the study, almost half (47.3%) of the patients were found to have CE. The risk factors associated with CE were bilateral frontal lobe contusion, unilateral frontal lobe contusion, cerebral contusion, subarachnoid hemorrhage, and abbreviated injury scale (AIS). The odds ratio values for these factors were 7.27 (95% confidence interval ( CI): 2.08 -25.42, p = 0.002), 2.85 (95% CI: 1.11 -7.31, p = 0.030), 2.62 (95% CI: 1.12 -6.13, p = 0.027), 2.44 (95% CI: 1.25 -4.76, p = 0.009), and 1.5 (95% CI: 1.10 -2.04, p = 0.009), respectively. We also observed that patients with mild/moderate TBI (AIS ≤ 3) had a 50% probability of developing CE 19.7 h after injury (χ 2= 13.82, adjusted R2 = 0.51), while patients with severe TBI (AIS > 3) developed CE after 12.5 h (χ 2= 18.48, adjusted R2 = 0.54). Finally, we conducted a receiver operator characteristic curve analysis of CE time, which showed an area under the curve of 0.744 and 0.672 for severe and mild/moderate TBI, respectively. Conclusion::Our study found that the onset of CE in individuals with TBI resulting from RTAs was correlated with the severity of the injury. Specifically, those with more severe injuries experienced an earlier onset of CE. These findings suggest that there is a critical time window for clinical intervention in cases of CE secondary to TBI.

The treatment strategy for blast injuries is closely linked to the clinical outcome of blast injury casualties. However, the application of military surgery experience to blast injuries caused by production safety accidents is relatively uncommon. In this study, the authors present 2 cases of blast injuries caused by one gas explosion, both cases involved individuals of the same age and gender and experienced similar degree of injury. The authors highlight the importance of using a military surgery treatment strategy, specifically emphasizing the need to understand the concept of damage control and disposal. It is recommended that relevant training in this area should be strengthened to improve the clinical treatment of such injuries. This study provides a valuable reference for healthcare professionals dealing with blast injuries.

AIM:To clarify the effect of macrophage PKM2 deficiency on mucosal repair in ulcerative colitis(UC).METHODS:The gene expression and metabolic profiles in UC patients were first analyzed based on the following databases:PXD001608,GSE193677,and GSE214695.Using the macrophage-specific PKM2 elimination mice(PKM2ΔMAC),the functions of PKM2 in dextran sulfate sodium(DSS)-induced UC were clarified in vivo by analyzing the body weight,disease activity index(DAI)scores,HE staining,immunohistochemical staining,and expression of muco-sal barrier markers.The impact of PKM2 on macrophage polarization was also investigated by flow cytometry,RNA se-quencing and RT-qPCR in mouse bone marrow-derived macrophages(BMDMs)and THP-1 cells in vitro.RESULTS:Bioinformatic analysis suggested that the intestinal tissues of UC patients preferred glycolysis.The expression of PKM was parallel to the severity of UC in patients,and the expression of PKM2,but not PKM1,was elevated in macrophages of UC mice.In the DSS-induced UC mice,macrophage-specific PKM2 elimination significantly alleviates the body weight loss,diarrhea,rectal bleeding,colonic shorten,as well as decreased DAI scores and mucosal tissue damage.The BMDMs de-rived from the PKM2ΔMAC mice preferred the M2 polarization upon LPS or IL-4 stimulation to that derived from the wild-type mice,as indicated by the F4/80+CD45+CD86+and F4/80+CD45+CD206+population,as well as the expression of Ocln,F11r and Tjp-1.The RNA sequencing results indicated significant gene differential expression in PKM2 knockout mouse macrophages,which was enriched in biological processes such as leukocyte migration,tissue remodeling,and cytokine in-teractions.Macrophage PKM2 deficiency promoted the expression of mucosal repair factors(Il8,Cxcl1,Ptgs2 and Wnt6),which was further validated in PKM2 knockout THP-1 cells.CONCLUSION:The PKM2 deficiency in macro-phages benifits the mucosal repair in UC status via facilitating the wound-healing macrophage polarization.
