Polycystic ovary syndrome （PCOS） is one of the most prevalent gynecological diseases， and its incidence is increasing year by year， seriously affecting the physical and mental health of female patients. The pathogenesis of this disease is complex and has not been fully clarified. At present， PCOS is mainly treated by Western medicine， which， however， has poor efficacy and induces various adverse reactions. Therefore， developing safe and effective therapies has become a difficult problem that needs to be solved. Studies have confirmed that traditional Chinese medicine （TCM） can regulate phosphatidylinositol 3-kinase/protein kinase B（PI3K/Akt）， mitogen-activated protein kinase/extracellular signal-regulated kinase （MAPK/ERK）， Toll-like receptor 4/nuclear factor-κB （TLR4/NF-κB）， transforming growth factor-β （TGF-β）/Smads， secreted glycoprotein/β-catenin （Wnt/β-catenin）， adenosine monophosphate-activated protein kinase （AMPK）， and advanced glycation endproduct/receptor for advanced glycation endproducts （AGE/RAGE） signaling pathways to ameliorate insulin resistance， inhibit inflammation and oxidative stress， regulate endocrine hormone disorders， and intervene in apoptosis and autophagy， thus alleviating the symptoms， slowing down the disease progression， and improving the ovarian function. The treatment of PCOS with TCM has demonstrated definite effects and high safety. Therefore， exploring this disease from cellular and molecular perspectives can provide a theoretical basis for its clinical treatment and new drug development. However， there is a lack of systematic reviews on the modulation of relevant signaling pathways by TCM in the treatment of PCOS. This article reviews the research progress in the treatment of PCOS with the active ingredients and compound prescriptions of TCM by regulating relevant signaling pathways in recent years， with the aim of providing evidence to support the promotion of TCM for treating PCOS in the future.

Turning to critical illness is a common stage of various diseases and injuries before death. Patients usually have complex health conditions, while the treatment process involves a wide range of content, along with high requirements for doctor′s professionalism and multi-specialty teamwork, as well as a great demand for time-sensitive treatments. However, this is not matched with critical care professionals and the current state of medical care in China. Telemedicine, which shortens the distance of medical professionals and the gap of disease diagnosis and treatments in various regions through electronic information, can effectively solve the current problem. Therefore, there is an urgent need to develop a standardized, high-quality visualization telemedicine round system .Therefore, experts have been organized to search domestic and foreign literature on telemedicine round for critically ill patients and to form this consensus based on clinical experiences so as to further improve the level of critical care treatments in regions.

Purpose To provide technical support for the use of echo-planar imaging(EPI)in the diagnosis of brain diseases,the image quality and diagnostic effect of single-shot echo-planar imaging(ssEPI)diffusion-weighted imaging(DWI)and multi-shot echo-planar imaging(msEPI)DWI sequences in the detection of brain diseases at 5.0T MR are analyzed.Materials and Methods A retrospective analysis was conducted on 42 patients with intracranial diseases who underwent T2-FLAIR,ssEPI DWI and msEPI DWI scans on a 5.0T MR system in the First Affiliated Hospital of USTC from August to September 2023.Two radiologists independently assessed image quality,measured distortion displacement,and compared signal-to-noise ratio,lesion-to-normal tissue contrast,contrast-to-noise ratio and apparent diffusion coefficient.Results msEPI sequence demonstrated significantly superior subjective scores,including geometric distortion,susceptibility artifacts,edge sharpness and overall image quality compared with those of ssEPI sequence(Z=5.728,4.197,5.766,5.777,all P<0.001).Quantitative analysis revealed substantial reduction in distortion displacement in msEPI sequence,including frontal lobe[(5.91±1.41)mm vs.(15.63±2.21)mm,t=34.050,P<0.001],anterior temporal lobe[(4.17±0.78)mm vs.(7.18±1.87)mm,t=12.263,P<0.001],posterior temporal lobe[(4.76±1.36)mm vs.(8.38±2.01)mm,t=21.336,P<0.001],cerebral diameter[(4.37±1.65)mm vs.(12.74±2.84)mm,t=23.255,P<0.001]and brainstem diameter[(0.80±0.63)mm vs.(1.98±1.63)mm,t=7.092,P<0.001],compared with ssEPI sequence.However,no statistically significant differences were observed in signal-to-noise ratio or contrast-to-noise ratio between the two sequences(P=0.848,0.638).Notably,msEPI sequences exhibited significantly enhanced lesion-normal tissue contrast compared with ssEPI sequences[221(131,311)vs.150(90,240),Z=3.89,P<0.001].Conclusion At 5.0T MRI,msEPI demonstrated superior image quality and diagnostic performance for craniocerebral diseases compared to ssEPI DWI sequences.

Objective To investigate the intervention effects and mechanism of Danggui Shaoyao power on spontaneous abortion rats.Methods A total of 60 first-day pregnant rats were randomly divided into normal group,model group,dydrogesterone group and Danggui Shaoyao power low,middle,and high dose groups,with 10 rats in each group.The low,middle,and high dose groups were given Danggui Shaoyao power 5.175 g·kg-1,10.35 g·kg-1,20.7 g·kg-1,respectively,from 1 to 12 days of gestation,and the dydrogesterone group was given dydrogesterone tablet solution 2 mg·kg-1 once a day.On the 13th day of gestation,rats model of spontaneous abortion was established by intragastric administration of 5 mg·kg-1 of mifepristone tablet solution except for the normal group.Serum levels of GnRH,FSH,LH,E2 were measured,and abortion rates and uterine coefficients were calculated.The pathological changes of pregnant uterus were observed by haematoxylin-eosin(HE)staining.The differential proteins in rats pregnant uterus were detected by Label-Free shotgun proteomic technique,and the PPI,Gene Ontology(GO),and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathways analysis of the differential proteins were analyzed.Immunohistochemistry was used to verify the expression levels of differential proteins.Results Compared with normal group,the serum levels of GnRH,FSH,LH,E2 and uterine coefficients were decreased,and the abortion rates were increased in model group(P<0.05).There were abortion lesions of spontaneous abortion in model group.Compared with model group,the serum levels of GnRH,FSH,LH,E2 and uterine coefficients were increased(P<0.05),and the abortion rates were decreased(P<0.05)in dydrogesterone group and Danggui Shaoyao power low,middle,and high dose groups.Proteomic results showed that a total of 550 proteins were quantified in this study.PPI analysis showed that a total of 159 proteins interacted with other proteins as hubs;the results of GO and KEGG enrichment analysis showed that the intervention effect of Danggui Shaoyao power on spontaneous abortion is related to the focal adhesion pathway,and involved upregulation of Akt2,Col6a1,Col6a2 and downregulation of Pten.Immunohistochemistry results showed that compared with normal group,the expression level of Akt2,Col6a1 and Col6a2 were decreased(P<0.05),and the expression level of Pten was increased(P<0.05)in model group.Compared with model group,the expression level of Akt2,Col6a1 and Col6a2 were increased(P<0.05),and the expression level of Pten was decreased(P<0.05)in dydrogesterone group and Danggui Shaoyao power low,middle,and high dose groups.Conclusions Danggui Shaoyao power has the intervention effect on spontaneous abortion,and its mechanism may be related to by demoting the protein expressions of Pten,and promoting the protein expressions of Akt2,Col6a1 and Col6a2.

Objective:To analyze the effect of rapid division of left Glisson pedicle and Arantius tube plane in laparoscopic anatomical left hemihepatectomy (LALH).Methods:Clinical data of 25 patients (15 with intrahepatic bile duct calculus and 10 with liver tumor) undergoing LALH in the Department of Hepatobiliary and Pancreatic Surgery, Jiangyin Hospital Affiliated to Nantong University from June 2020 to November 2024 were retrospectively analyzed, including 14 males and 11 females, aged (66.6±11.9) years. Among the patients, 15 received LALH with rapid division of left Glisson pedicle and Arantius tube plane in " one-clamp" fashion, and the others received LALH after traditional dissection of left Glisson pedicle. Age, sex, body mass index, time of left Glisson pedicle dissection, whether the MHV exposure, the time of liver transection, whether MHV and its important branches or bile duct injury occurred, intraoperative blood loss, the incidence of postoperative biliary leakage, the time of abdominal drainage remove, the hospital stay, and alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin, albumin 3 days after postoperative were compared between the groups.Results:The times of left Glisson pedicle dissection in the new-fasion and traditional group were (6.1±1.6) min and (13.8±3.0) min, and the time of liver transection was (24.9±3.5) min and (33.4±3.3) min, respectively ( t=-8.34, 6.08, P<0.001 for both). After division of left Glisson pedicle, the MHV was well exposed in 14 cases of new-fashion group and none of traditional group ( P<0.001). All the patients successfully completed the operation without conversion to laparotomy. Intraoperative blood loss, incidence of postoperative bile leakage, time of peritoneal drainage tube removal, postoperative hospital stay, AST, ALT, total bilirubin and albumin 3 days after surgery between the two groups were no significant differences (all P>0.05). Conclusion:LALH using the rapid division of left Glisson pedicle and Arantius tube plane in " one-clamp" fashion could be safe and feasible, the time of left Glisson pedicle and liver transection was short.

Objective:To evaluate the efficacy and safety of baricitinib combined with ruxolitinib cream in the treatment of progressive nonsegmental vitiligo.Methods:Clinical data were retrospectively collected from patients with progressive nonsegmental vitiligo in Boao Super Hospital. All the patients were treated with oral baricitinib daily (2 mg/day for patients weighing ≤ 50 kg; 4 mg/day for those > 50 kg) in combination with topical application of ruxolitinib cream twice daily for 24 consecutive weeks. Disease severity was assessed using the facial vitiligo area scoring index (F-VASI) and total body VASI (T-VASI) at baseline, week 12, and week 24. Adverse reactions were monitored throughout the treatment course.Results:Six patients with progressive nonsegmental vitiligo were collected, including 3 males and 3 females, aged 26 - 42 years, with the disease duration ranging from 0.5 to 25 years. At week 12, 3 patients achieved a 50% ~ < 75% improvement in facial vitiligo lesions (F-VASI 50), 1 patient achieved F-VASI 75 (75% ~ < 90% improvement), and 1 patient achieved T-VASI 50; at week 24, 4 patients achieved F-VASI 50, 1 patient achieved F-VASI 75, 1 patient achieved F-VASI 90 (≥ 90% improvement), and 3 patients achieved T-VASI 50. During the treatment, upper respiratory infection occurred in 1 patient, acne in 1 patient, pruritus in 2 patients, elevation of total cholesterol levels in 2 patients, and increase of high-density lipoprotein levels in 2 patients. No severe adverse events were observed during the treatment.Conclusion:The combination therapy with baricitinib and ruxolitinib cream may have potential efficacy and safety in the treatment of progressive nonsegmental vitiligo.

Objective:To observe the effect of point injection at Zusanli(ST36)plus abdominal point application on gastrointestinal dysfunction after laparoscopic surgery.Methods:A total of 204 patients with gastrointestinal dysfunction after laparoscopic surgery were recruited and divided into four groups using the random number table method,with 51 cases in each group.The control group received conventional postoperative intervention.In addition to the treatment in the control group,the point injection group was given point injection at Zusanli(ST36),the application group was offered abdominal point application,and the integrated group received point injection at Zusanli(ST36)and abdominal point application.The treatment lasted 3 consecutive days in all four groups.The recovery time of gastrointestinal function indicators and the incidence rate of postoperative nausea and vomiting(PONV)were observed and recorded.Before and after treatment,the visual analog scale(VAS)was used to assess abdominal pain intensity,the venous blood type 1 helper T cells/type 2 helper T cells(Th1/Th2)was determined,the serum levels of interleukin(IL)-6 and interferon(IFN)-γ were detected using the enzyme-linked immunosorbent assay,and the plasma levels of motilin and gastrin were measured using radioimmunoassay.Results:Compared to the control group,the first exhaust time,the first defecation time,and the time of restoring fluid diet came earlier in the other three groups(P<0.05)and were earlier in the integrated group than in the point injection and application groups(P<0.05).The point injection,application,and integrated groups had a lower PONV incidence rate than the control group,and the integrated group was lower than the point injection and application groups(P<0.05).The intra-group comparisons showed that the VAS score and the levels of IL-6 and INF-γ decreased after treatment in all four groups(P<0.05);the point injection,application,and integrated groups were lower than the control group(P<0.05),and the integrated group was lower than the point injection and application groups(P<0.05).The intra-group comparisons also demonstrated that the levels of Th1/Th2,motilin,and gastrin increased after the intervention in the four groups(P<0.05);the point injection,application,and integrated groups were higher than the control group(P<0.05),and the integrated group was higher than the point injection and application groups(P<0.05).Conclusion:Point injection at Zusanli(ST36)plus abdominal point application can encourage postoperative exhaust,defecation,and the recovery of diet fluid,alleviate postoperative abdominal pain,reduce PONV,balance Th1/Th2,and regulate the secretion of motilin and gastrin in patients with gastrointestinal dysfunction after laparoscopic surgery.
