OBJECTIVE To explore the antidepressant mechanism of Wenyang jieyu granules （WYJYG） via the NOD-like receptor thermal protein domain associated protein 3 （NLRP3）/apoptosis-associated speck-like protein containing a CARD （ASC）/Caspase-1 pathway. METHODS A rat model of depression was established by chronic unpredictable mild stress combined with single-housing for 42 consecutive days.The experiment set up blank group， model group， MCC950 （NLRP3 inflammasome inhibitor） group （10 mg/kg）， fluoxetine group （positive control，2.08 mg/kg），low-dose WYJYG（3.78 g/kg） and high-dose WYJYG group （7.56 g/kg），with 10 rats in each group. From the 22nd day of the experiment， rats in the fluoxetine group， low-dose and high-dose WYJYG groups were intragastrically administered with the corresponding drugs and intraperitoneally injected with an equal volume of normal saline. Rats in the MCC950 group were intraperitoneally injected with MCC950 at the corresponding concentration and intragastrically administered with an equal volume of distilled water. Rats in the blank group and model group were given an equal volume of distilled water by gavage and an equal volume of normal saline by intraperitoneal injection. All interventions were performed once a day for 21 consecutive days. Behavioral tests were conducted once a week. After the last administration， the contents of ASC， ionized calcium binding adaptor molecule 1 （Iba1）， interleukin-1β （IL-1β）， and IL-18 in hippocampal tissues were detected. The protein expressions of NLRP3， cluster of differentiation 68 （CD68）， Caspase-1， B-cell lymphoma-2 （Bcl-2）， and Bcl-2-associated X protein were determined， and neuronal apoptosis was observed. RESULTS After the last administration， compared with the model group， the open-field activity time was significantly prolonged （ P ＜0.05）， and the latency to feed in a novel environment was significantly shortened （ P ＜0.05） in rats of the high-dose WYJYG group. In hippocampal tissue， the contents of ASC， Iba1， IL-1β， and IL-18， as well as the protein expression levels of NLRP3， Caspase-1， and CD68， and the positive rate of neuronal apoptosis were all significantly decreased/downregulated （ P ＜0.05）. Bcl-2 protein expression was significantly upregulated （ P ＜0.05）， and the density of neuronal apoptosis-positive cells was significantly reduced （ P ＜0.05）. CONCLUSIONS WYJYG play on antidepressant role by inhibiting the NLRP3/ASC/Caspase-1 pathway， reducing microglia-mediated neuroinflammation， and inhibiting hippocampal neurons apoptosis.

Integrin α _v β ₃ is overexpressed in various tumor cells and angiogenesis. To date, no drug has been proven to target it for therapy. A first-in-human study was designed to investigate the safety, pharmacokinetics, and dosimetry of ¹⁷⁷Lu-AB-3PRGD2, a novel integrin α _v β ₃-targeting radionuclide drug with an albumin-binding motif to optimize the pharmacokinetics. Ten patients (3 men, 7 women; aged 45 ± 16 years) with integrin α _v β ₃-avid tumors were recruited to accept ¹⁷⁷Lu-AB-3PRGD2 injection in a dosage of 1.57 ± 0.08 GBq (42.32 ± 2.11 mCi), followed by serial scans to obtain its dynamic distribution in the body. Safety tests were performed before and every 2 weeks after the treatment for 6-8 weeks. No adverse event over grade 3 was observed. ¹⁷⁷Lu-AB-3PRGD2 was excreted mainly through the urinary system, with intense radioactivity in the kidneys and bladder. Moderate distribution was found in the liver, spleen, and intestines. The estimated blood half-life was 2.85 ± 2.17 h. The whole-body effective dose was 0.251 ± 0.047 mSv/MBq. The absorbed doses were 0.157 ± 0.032 mGy/MBq in red bone marrow and 0.684 ± 0.132 mGy/MBq in kidneys. This first-in-human study of ¹⁷⁷Lu-AB-3PRGD2 treatment indicates its promising potential for targeted radionuclide therapy of integrin α _v β ₃-avid tumors. It merits further studies in more patients with escalating doses and multiple treatment courses.

The pharmaceutical industry faces challenges in quality digitization for complex multi-stage processes, especially in small-sample systems. Here, an intelligent quality prediction and diagnostic (IQPD) framework was developed and applied to Tong Ren Tang's Niuhuang Qingxin Pills, utilizing four years of data collected from four production units, covering the entire process from raw materials to finished products. In this framework, a novel path-enhanced double ensemble quality prediction model (PeDGAT) is proposed, which combines a graph attention network and path information to encode inter-unit long-range and sequential dependencies. Additionally, the double ensemble strategy enhances model stability in small samples. Compared to global traditional models, PeDGAT achieves state-of-the-art results, with an average improvement of 13.18% and 87.67% in prediction accuracy and stability on three indicators. Additionally, a more in-depth diagnostic model leveraging grey correlation analysis and expert knowledge reduces reliance on large samples, offering a panoramic view of attribute relationships across units and improving process transparency. Finally, the IQPD framework integrates into a Human-Cyber-Physical system, enabling faster decision-making and real-time quality adjustments for Tong Ren Tang's Niuhuang Qingxin Pills, a product with annual sales exceeding 100 million CNY. This facilitates the transition from experience-driven to data-driven manufacturing.

ObjectiveTo analyze the expression level of triggering receptor expressed on myeloid cells-1 （TREM-1） in serum and ascites of patients with cirrhotic ascites， and to investigate its correlation with clinical features and inflammatory markers and its role in the diagnosis of infection and prognostic evaluation. MethodsA total of 110 patients with cirrhotic ascites who were hospitalized in The Fifth Hospital of Shijiazhuang from January 2019 to December 2020 were enrolled， and according to the presence or absence of intra-abdominal infection， they were divided into infection group with 72 patients and non-infection group with 38 patients. The patients with infection were further divided into improvement group with 38 patients and non-improvement group with 34 patients. Clinical data and laboratory markers were collected from all patients. Serum and ascites samples were collected， and ELISA was used to measure the level of TREM-1. The independent-samples t test was used for comparison of normally distributed continuous data between two groups； the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups， and the Kruskal-Wallis H test was used for comparison between multiple groups； the chi-square test was used for comparison of categorical data between two groups. A Spearman correlation analysis was used to investigate the correlation between indicators. A multivariate Logistic regression analysis was used to identify the influencing factors for the prognosis of patients with cirrhotic ascites and infection. The receiver operating characteristic （ROC） curve was used to evaluate the diagnostic and prognostic efficacy of each indicator， and the Delong test was used for comparison of the area under the ROC curve （AUC）. ResultsThe level of TREM-1 in ascites was significantly positively correlated with that in serum （r=0.50， P<0.001）. Compared with the improvement group， the non-improvement group had a significantly higher level of TREM-1 in ascites （Z=-2.391， P=0.017） and serum （Z=-2.544， P=0.011）， and compared with the non-infection group， the infection group had a significantly higher level of TREM-1 in ascites （Z=-3.420， P<0.001）， while there was no significant difference in the level of TREM-1 in serum between the two groups （P>0.05）. The level of TREM-1 in serum and ascites were significantly positively correlated with C-reactive protein （CRP）， procalcitonin （PCT）， white blood cell count， and neutrophil-lymphocyte ratio （r=0.288， 0.344， 0.530， 0.510， 0.534， 0.454， 0.330， and 0.404， all P<0.05）. The ROC curve analysis showed that when PCT， CRP， and serum or ascitic TREM-1 were used in combination for the diagnosis of cirrhotic ascites with infection， the AUCs were 0.715 and 0.740， respectively. The multivariate Logistic regression analysis showed that CRP （odds ratio ［OR］=1.019， 95% confidence interval ［CI］： 1.001‍ ‍—‍ ‍1.038， P=0.043） and serum TREM-1 （OR=1.002， 95%CI： 1.000‍ ‍—‍ ‍1.003， P=0.016） were independent risk factors for the prognosis of patients with cirrhotic ascites and infection， and the combination of these two indicators had an AUC of 0.728 in predicting poor prognosis. ConclusionThe level of TREM-1 is closely associated with the severity of infection and prognosis in patients with cirrhotic ascites， and combined measurement of TREM-1 and CRP/PCT can improve the diagnostic accuracy of infection and provide support for prognostic evaluation.

Objective To explore the accuracy of artificial intelligence-based diagnosis of ovarian malignant tumors and the identification of benign and malignant tumors under transabdominal scanning and transvaginal scanning methods. Methods A dataset of transabdominal and transvaginal two-dimensional ultrasound images was used and the images were preprocessed to enhance quality. The region of interest was segmented and divided into a training set and a test set. A convolutional neural network (CNN) was trained on the images in the training set, and the accuracy of the model on the test set was calculated. Results Transvaginal scanning was 14% more accurate in diagnosing malignant ovarian tumors than transabdo-minal scanning on the test set. For identifying the benign and malignant ovarian tumors containing cystic components, a mixture of transvaginal and transabdominal scanning increased the accuracy by 9.7% over transabdominal scanning alone. Conclusion CNN can identify ovarian malignant tumors under both scanning methods, but the accuracy of transvaginal scanning is higher than that of transabdominal scanning, and the CNN model has a higher accuracy in identifying benign and malignant ovarian tumors under transvaginal scanning.

Objective To investigate the relationship between calcium-sensing receptor(CaSR)gene rs17251221,rs60388563 loci polymorphisms and the genetic susceptibility of breast cancer(BC).Methods A total of 122 patients with breast cancer admitted to Hengshui Second People's Hospital from January 2022 to June 2024 were selected as the BC group,and 100 healthy women without blood relationship at the same time were selected as the control group.The polymorphisms of CaSR gene rs17251221,rs60388563 loci were detected by polymerase chain reaction(PCR).The clinical data,genotype distribution and allele frequency were compared between the two groups.Non-conditional Logistic regression model was used to analyze the correlation between CaSR gene polymorphism and genetic susceptibility of BC patients.Results Comparing the general data of the two group,the proportion of family history of cancer in the BC group was significantly higher than that in the control group,and the difference was statistically significant(t=12.246,P<0.05).The genotype distribution of CaSR gene rs17251221 and rs60388563 loci in the control group and the BC group was consistent with the Hardy-Weinberg equilibrium law(χ2=0.087～1.202,P＞0.05),which was representative of the population.Under the co-dominant model of rs17251221 and rs60388563 loci,the risk of BC in GG genotype was significantly increased(OR=1.493,95%CI=1.070～2.108;OR=1.483,95%CI=1.034～2.121).Under the dominant model(AA vs GA+GG)and recessive model(GG vs GA+AA),the rs17251221 locus carrying G allele(OR=1.371,95%CI=1.023～1.824)and A allele(OR=0.524,95%CI=0.221～0.926)was significantly associated with the risk of BC(P<0.05).Under the dominant model(CC vs GC+GG)and recessive model(GG vs GC+CC),the rs60388563 locus carrying G allele(OR=1.245,95%CI=1.107～1.461)and C allele(OR=0.682,95%CI=0.523～0.974)was significantly associated with the risk of BC(P<0.05).Conclusion The rs17251221,rs60388563 loci polymorphisms of CaSR gene are closely related to BC susceptibility,and the risk of BC is high in individuals carrying G allele.

Objective:Human papilloma virus(HPV)E6/E7mRNA in situ hybridization detection technology was used to explore whether high-grade squamous intraepithelial lesion(HSIL)of cervix with negative high-risk human papilloma virus(HR-HPV)typing test was caused by HPV infection,so as to provide new insights for the accurate diagnosis and treatment of cervical HSIL.Methods:305 tissue samples were collected from patients with HSIL who underwent cervical biopsy or surgical treatment in the Department of Gynecology,Affiliated Hospital of Shandong Second Medical University,from January 2020 to October2022.Patients with negative HR-HPV genoty-ping results(15 cases)were assigned to the study group,while those with positive results(290 cases)served as the control group.RNAscope in situ hybridization was used to detect the expression of HPV E6/E7 mRNA in the two groups,and the expression of HPV E6/E7 mRNA was analyzed by semi-quantitative scoring of staining inten-sity.Immunohistochemistry(IHC)was used to detect the expression of p16 and Ki-67.Results:①Among 305 pa-tients with HSIL,15 patients had negative HR-HPV typing test,with an incidence of 4.9％(15/305).②73.3％(11/15)of the study group showed positive expression of HPV E6/E7 mRNA,which was statistically significant compared with 100.0％(290/290)of the control group(P＜0.001).③The positive expression rate of p16 in the study group was significantly lower than that in the control group(93.3％vs.100.0％,P=0.049),while there was no significant difference in the positive expression rate of Ki-67 between the two groups(100.0％vs.100.0％).④In the samples with histopathological type cervical intraepithelial neoplasia(CIN)2,the overall score of HPV E6/E7 mRNA in the study group was significantly lower than that in the control group,which was statistically significant(P=0.004).In CIN3 samples,although the overall score of HPV E6/E7 mRNA in the study group was lower than that in the control group,there was no statistically significant difference(P=0.158).Conclusions:4.9％of pa-tients with HSIL in cervical cancer screening may be missed or misdiagnosed due to negative HR-HPV typing test.HPV E6/E7 mRNA in situ hybridization detection technology was helpful to reduce the false negative rate of HR-HPV typing test in HSIL,and it may assist in predicting the progression of cervical lesions,so as to provide a new idea for individualized precise treatment.

Split liver transplantation(SLT)has become an indispensable method for expanding the donor liver pool.However,advanced age in recipients can have significant adverse effects on prognosis.We report the case of an 82-year-old man with chronic liver failure and polycystic liver disease who underwent in vivo split right triple lobe donor liver transplantation on October 29,2021.The patient made a remarkable recovery and was discharged 1 month after surgery.To date,he has been followed up for 32 months,with favorable laboratory and imaging test results,and no significant abnormalities or complications.Currently,this patient may be the oldest SLT recipient in the world.With comprehensive preoperative evaluation,optimized surgical techniques,and individually tailored postoperative care,older adults can safely undergo SLT.Therefore,advanced age should not be considered an absolute contraindication for this procedure.
