Cholangiocarcinoma (CCA) is a malignant tumor originating from cholangiocytes. However, it remains unclear about the pathogenesis of this carcinoma, which may be related to multiple factors. Currently, CCA is mainly treated by surgery, chemotherapy, and radiotherapy. Among them, surgery is the only potentially curative option for CCA. Nevertheless, the high malignancy and asymptomatic nature of CCA may lead to poor treatment outcomes. It has been demonstrated that Chinese medicine (CM) plays a significant role in various antitumor applications. Meanwhile, CM exhibits fewer side effects and high availability. Moreover, the in vitro application of CM monomers has been explored in many domestic and foreign studies. This article mainly reviews the signaling pathways and molecular mechanisms of CM monomers in the treatment of CCA in recent years. These findings are expected to provide new insights into the treatment of CCA.

OBJECTIVE: To observe the clinical effect and safety of Lu'e Biyan Formula (LBF) combined with loratadine in the treatment of moderate to severe allergic rhinitis (AR) patients with Fei (Lung)-qi deficiency-coldness (FQDC) syndrome. METHODS: From September 2023 to December 2024, moderate to severe AR patients with FQDC syndrome were recruited from the Outpatient Department of Integrated Traditional Chinese and Western Medicine for Pulmonary Diseases Part 1, China-Japan Friendship Hospital. Participants were randomly assigned to a test group and a control group by using a random number table at a ratio of 1:1. Both groups received oral loratadine tablets (10 mg, once daily) for 2 weeks. In addition, the test group received oral LBF (30 mL, twice daily), and the control group received a placebo of LBF. Changes in the Total Nasal Symptom Score (TNSS), Total Non-nasal Symptom Score (TNNSS), Visual Analog Scale (VAS), Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ), and Chinese medicine (CM) syndrome scores before and after treatment were compared between groups. Moreover, the total effective rates and disease recurrence rates were compared. Adverse events (AEs) during the study period were also recorded. RESULTS: Totally 109 participants were recruited, and the full analysis set included 105 cases, 54 in the test group and 51 in the control group. Compared with the pre-treatment values, the scores of sneezing, runny nose, nasal obstruction, nasal itching, TNSS, TNNSS, VAS, RQLQ, and CM syndrome were significantly reduced in both groups at 1 and 2 weeks post-treatment and 12 weeks post-drug withdrawal (P<0.01). After treatment, the aforementioned scores in the test group were all markedly lower than those in the control group (P<0.01). Moreover, the total effective rate in the test group was higher than that in the control group (98.15% vs. 70.59%, P<0.01). After 12 weeks of drug withdrawal, there was no significant difference in the recurrence rate between groups (13.21% vs. 22.22%, P>0.05). No obvious AEs were observed in either group following treatment. CONCLUSIONS The combination of LBF with loratadine can effectively alleviate the symptoms of moderate to severe AR patients with FQDC syndrome, thereby improving their quality of life. This therapy demonstrated both precise effect and high safety. (Trial registration No. ITMCTR2025000589).

Objective: Exploring the mediating effect of perceived social support between the maternal personality traits and pregnancy-related anxiety. Methods: Singleton pregnant women who underwent antenatal checkups in the obstetrics department of general hospital affiliated to Ningxia Medical University from July to December 2021 were enrolled in this study to investigate perceived social support, pregnancy-related anxiety and conscious personality traits. Pearson correlation analysis was used to analyze the association between the maternal personality traits, perceived social support, and pregnancy-related anxiety, and the mediating effect of perceived social support was analyzed using Bootstrap method. Results: A total of 1 259 subjects were included in the study, of which 170 (13.50%) pregnant women felt introverted. The total score of perceived social support was (46.37±8.38), and 31.45% of pregnant women had high perceived social support. The total score of pregnancy-related anxiety was (21.48±5.53). The score of worry about fetal health was (10.09±3.24), and 368 (29.23%) of pregnant women had pregnancy-related anxiety. Maternal personality traits and pregnancy-related anxiety were negatively correlated (r=-0.076, P<0.05) and positively correlated with perceived social support during pregnancy (r= 0.127, P<0.05). Perceived social support during pregnancy and pregnancy-related anxiety were negatively correlated (r=-0.236, P<0.05). Perceived social support partially mediated the relationship between the maternal personality traits and pregnancy-related anxiety, with a relative effect value of 37.50%. Conclusion: The maternal personality traits, level of perceived social support and pregnancy-related anxiety are all related. Perceived social support could mediate the relationship between the maternal personality traits and pregnancy-related anxiety.

The discovery of regulatory cell death has led to new breakthroughs in the field of disease treatment. As a novel discovered regulatory cell death in the past decade, ferroptosis is characterized by abnormal increase of intracellular iron ions and peroxidative damage of cell membrane lipids, morphological features of mitochondrial volume reduction, increased mitochondrial membrane density, as well as mitochondria decrease or disappear. The mechanism of ferroptosis is mainly associated with factors such as iron metabolism disorder, lipid metabolism abnormality, amino acid antioxidant system imbalance and oxidative stress. Since the liver is the main organ of human body for storing iron ions, it is necessary to deeply investigate the mechanism of ferroptosis in liver diseases. Relevant studies have shown that ferroptosis plays different roles in various liver diseases and is closely related to the process of liver diseases, including drug-induced liver injury, alcoholic fatty liver disease, non-alcoholic fatty liver diseases, viral hepatitis, liver fibrosis and hepatocellular carcinoma. The aim of this review is to link ferroptosis and liver diseases, concentrating on the iron metabolism disorder, accumulation of lipid peroxides in cell membranes, imbalance of amino acid antioxidant system, hyperpolarization of mitochondrial membrane potential and its accumulation of lipid peroxides, oxidative stress-related transcription factors and other aspects. This review summarizes the regulatory mechanism, current situation and the roles of ferroptosis in liver diseases, in order to provide a new theoretical basis and ideas for the in-depth study of ferroptosis and the treatment of liver diseases.

Objective: To explore the heterogeneity and correlation of clinical phenotypes and genotypes in children with disorders of sex development (DSD). Methods: A retrospective study of 1 235 patients with clinically proposed DSD in 36 pediatric medical institutions across the country from January 2017 to May 2021. After capturing 277 DSD-related candidate genes, second-generation sequencing was performed to analyzed the heterogeneity and correlation combined with clinical phenotypes. Results: Among 1 235 children with clinically proposed DSD, 980 were males and 255 were females of social gender at the time of initial diagnosis with the age ranged from 1 day of age to 17.92 years. A total of 443 children with pathogenic variants were detected through molecular genetic studies, with a positive detection rate of 35.9%. The most common clinical phenotypes were micropenis (455 cases), hypospadias (321 cases), and cryptorchidism (172 cases) and common mutations detected were in SRD5A2 gene (80 cases), AR gene (53 cases) and CYP21A2 gene (44 cases). Among them, the SRD5A2 mutation is the most common in children with simple micropenis and simple hypospadias, while the AMH mutation is the most common in children with simple cryptorchidism. Conclusions: The SRD5A2 mutation is the most common genetic variant in Chinese children with DSD, and micropenis, cryptorchidism, and hypospadias are the most common clinical phenotypes. Molecular diagnosis can provide clues about the biological basis of DSD, and can also guide clinicians to perform specific clinical examinations. Target sequence capture probes and next-generation sequencing technology can provide effective and economical genetic diagnosis for children with DSD.

Objective To evaluate the effectiveness of a whole-process health education model among inpatients with ascites type of advanced schistosomiasis. Methods A “admission-hospitalization-discharge” whole-process health education model was created, 101 inpatients with ascites type of advanced schistosomiasis were given the whole-process health education. The scores of schistosomiasis control knowledge, attitudes towards schistosomiasis control and healthy behaviors, and awareness of schistosomiasis control knowledge, correct rate of attitudes towards schistosomiasis control and correct rate of healthy behaviors were compared among inpatients with ascites type of advanced schistosomiasis before and after implementation of the whole-process health education. Results The scores of schistosomiasis control knowledge, schistosomiasis control attitudes and healthy behaviors were all significantly higher among inpatients with ascites type of advanced schistosomiasis after implementation of the whole-process health education than before implementation (Z = −7.688, −3.576 and −4.328, all P values < 0.01). In addition, the awareness of schistosomiasis control knowledge increased from 54.3% to 82.7% (χ² = 188.886, P < 0.01), and the correct rate of attitudes towards schistosomiasis control increased from 88.4% to 98.0% (χ² = 22.001, P < 0.01), while the correct rate of healthy behaviors increased from 48.2% to 59.7% (χ² = 11.767, P < 0.01). Conclusions The whole-process health education model may remarkably improve the awareness of schistosomiasis control knowledge and promote the formation of positive attitudes towards schistosomiasis control and correct behaviors among inpatients with ascites type of advanced schistosomiasis, which is of great significance to facilitate patients’ cure.

Objective:To explore the protective effect of Gegen Qinliantang on the intestinal mucosal epithelial barrier function of ulcerative colitis （UC） mice， and to explore its mechanism of action in the treatment of ulcerative colitis via matrix metallopeptidase-9 （MMP-9）/p38 mitogen-activated protein kinase （p38 MAPK） signaling pathway. Method:The 48 female C57BL/6 mice were randomly divided into normal group， model group， sulfasalazine group （0.3 g·kg^-1） and Gegen Qinliantang high， medium and low dose groups （2.84，1.42，0.71 g·kg^-1）. The UC murine model was established by 3% dextran sulfate sodium （DSS）. Gegen Qinliantang and sulfasalazine were intragastrically administered on the 8^th day after the model was established for 7 days， and the normal group was treated with the same amount of normal saline. Colon tissues were collected after the last administration， and the pathological changes of colon tissues were detected by hematoxylin-eosin （HE） staining. The expression of tight junction （TJ） proteins such as Occludin and zonula occludens-1（ZO-1） in colon tissues was detected by immunohistochemistry （IHC）， and the expression levels of tumor necrosis factor-alpha （TNF-α）， interleukin-1β （IL-1β）， and MMP-9 mRNA in colon tissues were detected by Real-time polymerase chain reaction （Real-time PCR）. The expression of phosphorylated p38 MAPK （p-p38 MAPK）， p38 MAPK and MMP-9 protein in colon tissues was detected by Western blot. Result:Compared with normal group， the body weight of mice decreased （P<0.01） and disease activity index （DAI） score increased significantly （P<0.01） in model group， the colon tissues of the model group were damaged more obviously， the expression of occludin and ZO-1 proteins in model group was significantly reduced （P<0.01）， and the relative expression levels of TNF-α， IL-1β， and MMP-9 mRNA in model group were significantly increased （P<0.01）， the expression of p-p38 MAPK and MMP-9 in model group was significantly increased （P<0.01）. Compared with model group， the body mass and DAI score of the sulfasalazine group and Gegen Qinliantang group were significantly improved （P<0.05，P<0.01）， the colonic tissues damage were significantly improved， and the expression of Occludin and ZO-1 protein was significantly increased （P<0.05，P<0.01）， the relative expression levels of TNF-α， IL-1β， and MMP-9 mRNA were significantly decreased （P<0.01）， and the expression of p-p38 MAPK and MMP-9 was significantly decreased （P<0.01）. The changes in the middle dose group were the most obvious among the various dose groups of Gegen Qinliantang. Conclusion:Gegen Qinliantang repairs the intestinal mucosal barrier function by inhibiting the expressions of MMP-9 and inflammatory cytokines such as TNF-α and IL-1β， blocking the activation of the p38 MAPK signaling pathway， and increasing the expressions of tight junction protein.

Objective:To investigate the therapeutic effect of polydatin on ulcerative colitis （UC） in mice and its regulation of protein kinase Cθ（PKCθ）/signal transducer and activator of transcription 3（STAT3） signaling on T helper cell 17（Th17） and its mechanism in the treatment of UC. Method:The 32 male C57BL/6 mice were randomly divided into normal group， model group， polydatin group （0.045 g·kg^-1） and sulfasalazine group （0.5 g·kg^-1）. The UC model was established by giving 3% dextran sodium sulfate （DSS） solution to free drinking water in mice. Polydatin and sulfasalazine groups were given by gavage 0.5 h before modeling for 7 days. The normal group and model group were given the same amount of normal saline. After the last administration， the colonic tissue was taken and hematoxylin-eosin （HE） was used to observe the pathological changes of colonic tissue. Flow cytometry was used to detect the proportion of Th17 in the lamina propria of colonic mucosa. The expression of interleukin-17A （IL-17A） in serum was detected by enzyme-linked immunosorbent assay （ELISA）. Polydatin was added to CD4⁺ T cells purified from spleen of C57BL/6 mice by magnetic-activated cell sorting （MACS） under the stimulation of cell stimulation cocktail in vitro in order to detect its impact on PKCθ and STAT3 phosphorylation. Result:Compared with normal group， the body weight was significantly decreased， and disease activity index （DAI） scores of the model group was significantly increased （P<0.01）， the colonic mucosal epithelium was damaged and inflammatory cells infiltration in the mucosa and submucosa was obvious， the proportion of Th17 in the lamina propria of colonic mucosa was significantly increased （P<0.01）， and the content of serum IL-17A was significantly increased （P<0.01）. Compared with the model group， the weight and DAI score of polydatin and sulfasalazine groups were significantly improved （P<0.01）， the degree of colon tissue damage was significantly improved， the proportion of Th17 in colon mucosa lamina propria was significantly decreased （P<0.01）， and the content of IL-17A in serum was significantly decreased （P<0.01）. In vitro experiments showed that polydatin could significantly inhibit the phosphorylation of PKCθ and STAT3 in Th17 （P<0.01） as well as IL-17A secretion. Conclusion:Polydatin can improve the ulcerative colitis in mice via inhibiting the phosphorylation of PKCθ and STAT3 to preclude IL-17A secreting in Th17.

Objective:Death causes and life reduction of malignant tumors in the residents of Zhuanqiao Town in Minhang District from 2013 to 2017 were analyzed to provide scientific evidence for the strategies on comprehensive prevention and control of cancer. Methods:The data of death causes of malignant tumors in the residents of Zhuanqiao Town were collected and analyzed. The mortality rate， annual percent change （APC）， composition ratio， potential years of life lost （PYLL）， potential years of life lost rate （PYLLR） and average years of life lost （AYLL） of the registered population were analyzed. Results:The standardized mortality rate of malignant tumors in the residents of Zhuanqiao Town from 2013 to 2017 was 128.05/10⁵， and the rate was higher in males than that in females. The top four cancers regarding PYLL were lung cancer， liver cancer， stomach cancer and colorectal cancer， which were roughly the same order as the top four regarding the mortality. This indicates that these four cancers had a greater impact on residents. Lung cancer had a greater impact on female life expectancy. PYLL and SPYLL ranked the first in liver cancer in males and thus had a greater impact on the males. Breast cancer was one of the most important malignant tumors in causing early death of women. Conclusion:Malignant tumor has become an important public health problem endangering the health of residents. The focus of future work in the town remains to improve public awareness of carcinogenic risk factors， actively carry out health education， lifestyle intervention and early screening in order to reduce cancer risk， alleviate cancer burden and improve the life expectancy of residents.
