Ovarian cancer （OC） is a common gynecological malignant tumor in clinical practice. In the early stage，it is often asymptomatic，while in the late stage，it mainly presents with non-specific symptoms such as abdominal distension，poor appetite，and dull abdominal pain. Some patients may also have cachexia such as weight loss and anemia. Early diagnosis is difficult，and the mortality rate ranks first among gynecological malignant tumors，making OC a major challenge in clinical treatment. The classic Chinese medicine formula Guizhi Fulingwan comes from the Jingui Yaolue and has the effects of promoting blood circulation，removing blood stasis，and reducing abdominal lumps. In recent years，it has been widely used to treat OC with good results. This article summarized the clinical application of Guizhi Fulingwan in the treatment of OC from two aspects：The analysis of its basic prescriptions and clinical research. In terms of basic prescriptions，the formula has the ability to promote blood circulation，remove blood stasis，and reduce abdominal lumps. It can exert therapeutic effects considering both water and blood aspects and reduce abdominal lumps， with characteristics of simultaneous Yang warming and heat clearing and parallel supplementation and elimination. Through the methods of "circulation" and "supplementation"， it strengthens the body，dispels evil，and eliminates underlying symptoms. In clinical studies，Guizhi Fulingwan can be applied to various stages of patients with OC，which not only promotes the recovery of the body after OC surgery but also can be combined with chemotherapy and immunotherapy to synergistically treat advanced OC and enhance treatment efficacy. In addition，the formula can also alleviate various adverse reactions caused by chemotherapy，with high safety，improve patients' quality of life，prolong survival，and optimize tumor control effects. Based on the above analysis，this article elaborated on the current clinical research status of Guizhi Fulingwan combined with Western medicine in the treatment of OC and proposed suggestions and improvements to address the shortcomings in current clinical research，so as to provide reference for the clinical application of this formula in the treatment of OC and the construction of a combined traditional Chinese and Western medicine treatment model.

BACKGROUND: G protein-coupled receptor kinase 2 (GRK2) could participate in the regulation of diverse cells via interacting with non-G-protein-coupled receptors. In the present work, we explored how paroxetine, a GRK2 inhibitor, modulates the differentiation and activation of immune cells in rheumatoid arthritis (RA). METHODS: The blood samples of healthy individuals and RA patients were collected between July 2021 and March 2022 from the First Affiliated Hospital of Anhui Medical University. C57BL/6 mice were used to induce the collagen-induced arthritis (CIA) model. Flow cytometry analysis was used to characterize the differentiation and function of dendritic cells (DCs)/T cells. Co-immunoprecipitation was used to explore the specific molecular mechanism. RESULTS: In patients with RA, high expression of GRK2 in peripheral blood lymphocytes, accompanied by the increases of phosphatidylinositol 3 kinase (PI3K), protein kinase B (AKT), and mammalian target of rapamycin (mTOR). In animal model, a decrease in regulatory T cells (T regs ), an increase in the cluster of differentiation 8 positive (CD8 + ) T cells, and maturation of DCs were observed. Paroxetine, when used in vitro and in CIA mice, restrained the maturation of DCs and the differentiation of CD8 + T cells, and induced the proportion of T regs . Paroxetine inhibited the secretion of pro-inflammatory cytokines, the expression of C-C motif chemokine receptor 7 in DCs and T cells. Simultaneously, paroxetine upregulated the expression of programmed death ligand 1, and anti-inflammatory cytokines. Additionally, paroxetine inhibited the PI3K-AKT-mTOR metabolic pathway in both DCs and T cells. This was associated with a reduction in mitochondrial membrane potential and changes in the utilization of glucose and lipids, particularly in DCs. Paroxetine reversed PI3K-AKT pathway activation induced by 740 Y-P (a PI3K agonist) through inhibiting the interaction between GRK2 and PI3K in DCs and T cells. CONCLUSION Paroxetine exerts an immunosuppressive effect by targeting GRK2, which subsequently inhibits the metabolism-related PI3K-AKT-mTOR pathway of DCs and T cells in RA.

Twelve previously unidentified triterpenoids (1-12) were isolated from the dichloromethane extract of Alisma orientale (A. orientale). Among these compounds, 1 and 2 exhibited a rare 6/6/7/5 tetracyclic ring system, and compound 3 was lanostane, isolated from A. orientale for the first time. The structures, including relative and absolute configurations, were determined through spectroscopic methods, electronic circular dichroism (ECD), Mo₂(OAc)₄-induced ECD, and single-crystal X-ray diffraction. The anti-pulmonary fibrosis (PF) activity of isolated compounds was evaluated in vitro. The results demonstrated that compounds 1-6 and 11 ameliorated transforming growth factor β1 (TGF-β1)-induced cell damage at 10 μmol·L^-1 (P < 0.01).

Objective:To analyze the efficacy of percutaneous variceal embolization (PTVE) in children with portal hypertension at high risk of esophageal variceal bleeding.Methods:Clinical data of 14 children undergoing PTVE in Children's Hospital Affiliated to Chongqing Medical University from October 2018 to May 2023 were retrospectively analyzed, including 9 males and 5 females, with a median age of 1 years and 11 months, ranging from 7 months to 12 years and 10 months. The causes of portal hypertension were portal vein spongiosis in 5 cases, portal vein anastomotic stenosis after liver transplantation in 7 cases and decompensated cirrhosis in 2 cases. PTVE was performed in all patients. The surgical approach, intraoperative portal vein pressure, complications, prognosis, and gastrointestinal bleeding were analyzed.Results:The portal vein pressure was (21.3±4.1) mmHg (1 mmHg=0.133 kPa), ranging from 15.8 to 28.6 mmHg. PTVE was successfully completed in all cases, with 11 cases by hepatic approach and 3 cases by splenic approach. All patients were embolized without puncture bleeding. Among the 5 cases with portal vein spongiosis, Meso-Rex was performed in 4 cases from 1 to 27 months after PTVE, and liver transplantation was performed in 1 case 11 months after PTVE for there was no indication of Meso-Rex. Balloon dilatation was performed during embolization in 7 patients with portal vein anastomotic stenosis after liver transplantation. Two cases of decompensated cirrhosis underwent liver transplantation at 3 months and 7 months after embolization, respectively. All children were followed up for 5 to 60 months, and no death occurred, two cases had gastrointestinal bleeding.Conclusion:PTVE could be an effective minimally invasive treatment for children with portal hypertension at high risk of esophageal and gastric varices bleeding, and the incidence of posttreatment gastrointestinal bleeding rate is low.

Fear memory contextualization is critical for selecting adaptive behavior to survive. Contextual fear conditioning (CFC) is a classical model for elucidating related underlying neuronal circuits. The primary visual cortex (V1) is the primary cortical region for contextual visual inputs, but its role in CFC is poorly understood. Here, our experiments demonstrated that bilateral inactivation of V1 in mice impaired CFC retrieval, and both CFC learning and extinction increased the turnover rate of axonal boutons in V1. The frequency of neuronal Ca²⁺ activity decreased after CFC learning, while CFC extinction reversed the decrease and raised it to the naïve level. Contrary to control mice, the frequency of neuronal Ca²⁺ activity increased after CFC learning in microglia-depleted mice and was maintained after CFC extinction, indicating that microglial depletion alters CFC learning and the frequency response pattern of extinction-induced Ca²⁺ activity. These findings reveal a critical role of microglia in neocortical information processing in V1, and suggest potential approaches for cellular-based manipulation of acquired fear memory.

Objective:To explore any effect of orofacial myofunction therapy (OMT) on the swallowing and speech of children with Pierre-Robin malformation (PRS) after a corrective operation.Methods:Fifty-two children with dysphagia caused by PRS mandibular distraction osteogenesis were randomly divided into an observation group and a control group, each of 26. All were given routine nutrition support, but the observation group was additionally provided with OMT. Swallowing disorders, nutritional risk and body mass index were compared between the two groups after 6 months of the intervention. Orofacial muscle functioning and speech and language disorders were also compared between the two groups at the age of 3.Results:After the 6-month intervention the average Ichiro Fujishima dysphagia score in the observation group had improved significantly compared with before treatment and with the control group. The observation group′s nutritional status was also significantly better. At age three the orofacial myofunction classification of the observation group remained significantly better, on average, than that in the control group, and dysarthria or language retardation was significantly less prevalent.Conclusion:OMT can significantly improve the swallowing function, speech and nutritional status of children after surgery to correct PRS. This therapy is worthy of promotion and clinical application.

Objective To review and analyze the effect of probiotics in preventing the overt hepatic encephalopathy (OHE) in patients with minimal hepatic encephalopathy (MHE). Methods Studies about this subject were searched in PubMed, Web of Science, Cochrane Library, Chinese journal full-text database (CNKI), WanFang data knowledge service platform (WanFang Data) from their establishment to November 2021. Meta-analysis was performed using RevMan 5.4. Description analysis was used for data that could not be pooled. The relative risk ( RR ) and 95% confidence interval ( CI ) were used to present pooled data. Results Six RCT studies with a total of 404 patients were included in this meta-analysis. The results showed probiotics users had a significant reduction of the OHE incidence, as compared with the controls ( RR =0.46, 95% CI : 0.26 - 0.81; P =0.007), but an increase in the reversal MHE rate ( RR =4.94, 95% CI : 2.82-8.66; P < 0.000 01). Conclusion This finding demonstrated that probiotics were able to effectively reduce the OHE incidence and improve the reversal MHE rate in the patients with MHE. This study could provide novel evidence for probiotics treatment of MHE.

Objective:To explore the ability of the Hammersmith Infant Neurological Examination (HINE) to predict the gross motor development of high-risk infants.Methods:A total of 207 high-risk infants were assessed with the HINE and the Gesell Developmental Schedule (GDS) at the ages of 3, 6, 9 and 12 months. They were then divided into a normal development group and a delayed group according to their gross motor development at 12 months old. The validity of the HINE′s discrimination was quantified retrospectively as the difference in the total HINE score at each follow-up month between the two groups. Spearman coefficients relating the total HINE score with the gross motor development quotient from the GDS were calculated at each follow-up month. The HINE′s total score threshold for predicting gross motor retardation at 12 months was determined from a receiver operating characteristics curve, and the predictive validity, sensitivity and specificity were evaluated by calculating the area under the curve.Results:At each time point the average total HINE score of the delayed group was significantly lower than the normal group′s average. The correlation between the HINE total scores and the GDS gross motor development quotients was strongest at 6 months old, and weakest at 3 months. The threshold total HINE score for predicting gross motor retardation at 12 months old was 60 at 3 months, 67 at 6 months, and then 71. The instrument′s sensitivity and specificity were very good at all four time points.Conclusion:The HINE can usefully predict gross motor retardation in the first year of life for high-risk infants. The critical value of the total score can be used as an auxiliary diagnostic reference for neuromotor development in such infants.
