Perineural invasion (PNI) by tumor cells is a key phenotype of highly-invasive oral squamous cell carcinoma (OSCC). Since Schwann cells (SCs) and fibroblasts maintain the physiological homeostasis of the peripheral nervous system, and we have focused on cancer-associated fibroblasts (CAFs) for decades, it's imperative to elucidate the impact of CAFs on SCs in PNI⁺ OSCCs. We describe a disease progression-driven shift of PNI^- towards PNI⁺ during the progression of early-stage OSCC (31%, n = 125) to late-stage OSCC (53%, n = 97), characterized by abundant CAFs and nerve demyelination. CAFs inhibited SC proliferation/migration and reduced neurotrophic factors and myelin in vitro, and this involved up-regulated ER stress and decreased MAPK signals. Moreover, CAFs also aggravated the paralysis of the hind limb and PNI in vivo. Unexpectedly, leukemia inhibitory factor (LIF) was exclusively expressed on CAFs and up-regulated in metastatic OSCC. The LIF inhibitor EC330 restored CAF-induced SC inactivation. Thus, OSCC-derived CAFs inactivate SCs to aggravate nerve injury and PNI development.

Resistance to poly adenosine diphosphate (ADP)-ribose polymerase inhibitor (PARPi) presents a considerable obstacle in the treatment of ovarian cancer. F-box and tryptophan-aspartic (WD) repeat domain containing 11 (FBXW11) modulates the ubiquitination of growth-and invasion-related factors in lung cancer, colorectal cancer, and osteosarcoma. The function of FBXW11 in PARPi therapy is still ambiguous. In this study, RNA sequencing (RNA-seq) showed that FBXW11 expression was raised in ovarian cancer cells that had been treated with PARPi. FBXW11 was abnormally expressed at low levels in high-grade serous ovarian cancer (HGSOC) tissues, and low levels of FBXW11 were associated with shorter overall survival (OS) and progression-free survival (PFS) in HGSOC patients. Overexpressing FBXW11 made ovarian cancer more sensitive to PARPi, while knocking down FBXW11 made it less sensitive. The four-dimensional (4D) label-free quantitative proteomic analysis revealed that FBXW11 targeted S100 calcium binding protein A11 (S100A11) and promoted its degradation through ubiquitination. The increased degradation of S100A11 led to less efficient DNA damage repair, which in turn contributed to increased PARPi-induced DNA damage. The role of FBXW11 in promoting PARPi sensitivity was also confirmed in xenograft mouse models. In summary, our study confirms that FBXW11 promotes the susceptibility of ovarian cancer cells to PARPi via affecting S100A11-mediated DNA damage repair.

Objective:To evaluate the diagnostic efficacy and practicality of the Jaundice color card (JCard) as a screening tool for neonatal jaundice.Methods:Following the standards for reporting of diagnostic accuracy studies (STARD) statement, a multicenter prospective study was conducted in 9 hospitals in China from October 2019 to September 2021. A total of 845 newborns who were admitted to the hospital or outpatient department for liver function testing due to their own diseases. The inclusion criteria were a gestational age of ≥35 weeks, a birth weight of ≥2 000 g, and an age of ≤28 days. The neonate′s parents used the JCard to measure jaundice at the neonate′s cheek. Within 2 hours of the JCard measurement, transcutaneous bilirubin (TcB) was measured with a JH20-1B device and total serum bilirubin (TSB) was detected. The Pearson′s correlation analysis, Bland-Altman plots and the receiver operating characteristic (ROC) curve were used for statistic analysis.Results:Out of the 854 newborns, 445 were male and 409 were female; 46 were born at 35-36 weeks of gestational age and 808 were born at ≥37 weeks of gestational age. Additionally, 432 cases were aged 0-3 days, 236 cases were aged 4-7 days, and 186 cases were aged 8-28 days. The TSB level was (227.4±89.6) μmol/L, with a range of 23.7-717.0 μmol/L. The JCard level was (221.4±77.0) μmol/L and the TcB level was (252.5±76.0) μmol/L. Both the JCard and TcB values showed good correlation ( r=0.77 and 0.80, respectively) and agreements (96.0% (820/854) and 95.2% (813/854) of samples fell within the 95% limits of agreement, respectively) with TSB. The JCard value of 12 had a sensitivity of 0.93 and specificity of 0.75 for identifying a TSB ≥205.2?μmol/L, and a sensitivity of 1.00 and specificity of 0.35 for identifying a TSB ≥342.0?μmol/L. The TcB value of 205.2?μmol/L had a sensitivity of 0.97 and specificity of 0.60 for identifying TSB levels of 205.2 μmol/L, and a sensitivity of 1.00 and specificity of 0.26 for identifying TSB levels of 342.0 μmol/L. The areas under the ROC curve (AUC) of JCard for identifying TSB levels of 153.9, 205.2, 256.5, and 342.0 μmol/L were 0.96, 0.92, 0.83, and 0.83, respectively. The AUC of TcB were 0.94, 0.91, 0.86, and 0.87, respectively. There were both no significant differences between the AUC of JCard and TcB in identifying TSB levels of 153.9 and 205.2 μmol/L (both P>0.05). However, the AUC of JCard were both lower than those of TcB in identifying TSB levels of 256.5 and 342.0 μmol/L (both P<0.05). Conclusions:JCard can be used to classify different levels of bilirubin, but its diagnostic efficacy decreases with increasing bilirubin levels. When TSB level are ≤205.2 μmol/L, its diagnostic efficacy is equivalent to that of the JH20-1B. To prevent the misdiagnosis of severe jaundice, it is recommended that parents use a low JCard score, such as 12, to identify severe hyperbilirubinemia (TSB ≥342.0 μmol/L).

Objective:To analyze the influential factors of blurred vision after general anesthesia.Methods:The clinical data of 997 patients who underwent elective general anesthesia at The No. 1 People's Hospital of Pinghu from September 2022 to May 2023 were retrospectively analyzed. The data collected included age, sex, body mass index, American Society of Anesthesiologists classification, history of hypertension, history of diabetes, operation duration (specifically whether it exceeded 3 hours), surgical position (whether the patient was in the supine position), operating room temperature, use of penehyclidine hydrochloride, use of muscle relaxant antagonists, use of atropine, blood pressure (specifically whether it was ≥ 30% of the baseline value), fluid input, blood loss, and use of pneumoperitoneum. Collinearity diagnosis and univariate logistic regression analysis were conducted to select factors with statistical significance. Subsequently, multivariate logistic regression analysis was performed.Results:Univariate and multivariate logistic regression analyses showed that age > 65 years ( OR = 1.47, 95% CI: 1.01-2.15, P = 0.043), surgical position (non-supine position) ( OR = 1.54, 95% CI: 1.06-2.25, P = 0.025), operation time exceeding 3 hours ( OR = 1.76, 95% CI: 1.05-2.94, P = 0.031), and the use of penehyclidine hydrochloride ( OR = 4.91, 95% CI: 3.35-7.21, P < 0.001) were identified as factors contributing to postoperative blurred vision in patients undergoing general anesthesia. Conclusion:Factors contributing to postoperative blurred vision in patients undergoing general anesthesia include age > 65 years, the use of penehyclidine hydrochloride during surgery, operation time exceeding 3 hours, and non-supine surgical position. Clinically, it is essential to implement early and effective preoperative education, enhance intraoperative nursing quality, and optimize preoperative medication for general anesthesia to reduce the incidence of blurred vision after surgery.

Objective To analyze the characteristics of time in range(TIR)and its relationship with oxidative stress(OS)and insulin resistance status(HOMA-IR)in patients with type 2 diabetes mellitus(T2DM)and sleep apnea-hypopnea syndrome(OSAHS).Methods According to apnea-hypopnea index(AHI),165 T2DM in patients were divided into simple T2DM group(AHI<5 times/h,n=43),T2DM combine OSAHS mild group(OSAHS-G,5≤AHI<15 times/h,n=51),T2DM combined OSAHS moderate group(OSAHS-M,15≤AHI≤30 times/h,n=40)and T2DM combine OSAHS severe group(OSAHS-S,AHI>30 times/h,n=31).TIR was calculated by dynamic blood glucose monitoring.Superoxide dismutase(SOD),glutathione peroxidase(GSH-Px)and other indexes were detected and analyzed.Results Compared with simple T2DM group,the levels of HOMA-IR,8-iso-PGF2a and Ox-LDL were higher in T2DM combined OSAHS-G,OSAHS-M or OSAHS-S group,while the levels of TIR,SOD and GSH-Px were lower(P<0.05).Pearson correlation analysis showed that TIR was positively correlated with the levels of SOD and GSH-Px(P<0.05 or P<0.01),and negatively correlated with the levels of 8-iso-PGF2a,Ox-LDL,HbA1c,HOMA-IR and the severity of OSAHS(P<0.01).Logistic regression analysis showed that TIR,SOD and GSH-Px were protective factors for severe OSAHS in T2DM patients,while 8-iso-PGE2a and Ox-LDL were the risk factors for severe OSAHS.Conclusions The glucose level fluctuates greatly in patients with T2DM and OSAHS.Insulin resistance and oxidative stress are factors that affect the normalization of TIR.

Neoadjuvant therapy for locally advanced colorectal cancer has made great progress in the past 20 years, but there are still limitations such as side effects, organ dysfunction and unsatisfactory control of metastasis. In recent years, with the improvement of surgical techniques and further development of molecular research, how to further improve local control, reduce distant metastasis, and even avoid surgery according to clinical remission to achieve organ preservation, is the current demand and research goal. With the advancement of molecular research, colorectal cancer has different treatment strategies based on microsatellite status. For patients with microsatellite instability locally advanced colorectal cancer, immune checkpoint inhibitor therapy significantly increased the pathologic complete response rate, reduced the incidence of adverse events and improved organ function compared with conventional chemoradiotherapy. For patients with microsatellite stable locally advanced colon cancer, neoadjuvant therapy is still in the exploratory stage. The standard of care is surgery combined with perioperative chemotherapy. For microsatellite stable locally advanced rectal cancer, the complete response rate is improved by enhancing neoadjuvant therapy, which helps to preserve organs. On the other hand, selective radiotherapy preserves organ function and improves quality of life. This article reviews the neoadjuvant treatment strategies for locally advanced colorectal cancer based on organ-sparing strategies.

Objective Kisspeptin,a protein encoded by the KISS1 gene,functions as an essential factor in suppressing tumor growth.The intricate orchestration of cellular processes such as proliferation and differentiation is governed by the Notch1/Akt/Foxo1 signaling pathway,which assumes a central role in maintaining cellular homeostasis.In the specific context of this investigation,the focal point lies in a meticulous exploration of the intricate mechanisms underlying the regulatory effect of kisspeptin on the process of endometrial decidualization.This investigation delves into the interplay between kisspeptin and the Notch1/Akt/Foxo1 signaling pathway,aiming to elucidate its significance in the pathophysiology of recurrent spontaneous abortion(RSA).Methods We enrolled a cohort comprising 45 individuals diagnosed with RSA,who were admitted to the outpatient clinic of the Reproductive Center at the Second Affiliated Hospital of Soochow University between June 2020 and December 2020.On the other hand,an additional group of 50 women undergoing elective abortion at the outpatient clinic of the Family Planning Department during the same timeframe was also included.To comprehensively assess the molecular landscape,Western blot and RT-qPCR were performed to analyze the expression levels of kisspeptin(and its gene KISS1),IGFBP1(an established marker of decidualization),Notch1,Akt,and Foxo1 within the decidua.Human endometrial stromal cells(hESC)were given targeted interventions,including treatment with siRNA to disrupt KISS1 or exposure to kisspeptin10(the bioactive fragment of kisspeptin),and were subsequently designated as the siKP group or the KP10 group,respectively.A control group comprised hESC was transfected with blank siRNA,and cell proliferation was meticulously evaluated with CCK8 assay.Following in vitro induction for decidualization across the three experimental groups,immunofluorescence assay was performed to identify differences in Notch1 expression and decidualization morphology between the siKP and the KP10 groups.Furthermore,RT-qPCR and Western blot were performed to gauge the expression levels of IGFBP1,Notch1,Akt,and Foxo1 across the three cell groups.Subsequently,decidualization was induced in hESC by adding inhibitors targeting Notch1,Akt,and Foxo1.The expression profiles of the aforementioned proteins and genes in the four groups were then examined,with hESC induced for decidualization without adding inhibitors serving as the normal control group.To establish murine models of normal pregnancy(NP)and RSA,CBA/J×BALB/c and CBA/J×DBA/2 mice were used.The mice were respectively labeled as the NP model and RSA model.The experimental groups received intraperitoneal injections of kisspeptin10 and kisspeptin234(acting as a blocker)and were designated as RSA-KP10 and NP-KP234 groups.On the other hand,the control groups received intraperitoneal injections of normal saline(NS)and were referred to as RSA-NS and NP-NS groups.Each group comprised 6 mice,and uterine tissues from embryos at 9.5 days of gestation were meticulously collected for observation of embryo absorption and examination of the expression of the aforementioned proteins and genes.Results The analysis revealed that the expression levels of kisspeptin,IGFBP1,Notch1,Akt,and Foxo1 were significantly lower in patients diagnosed with RSA compared to those in women with NP(P<0.01 for kisspeptin and P<0.05 for IGFBP1,Notch1,Akt,and Foxo1).After the introduction of kisspeptin10 to hESC,there was an observed enhancement in decidualization capability.Subsequently,the expression levels of Notch1,Akt,and Foxo1 showed an increase,but they decreased after interference with KISS1.Through immunofluorescence analysis,it was observed that proliferative hESC displayed a slender morphology,but they transitioned to a rounder and larger morphology post-decidualization.Concurrently,the expression of Notch1 increased,suggesting enhanced decidualization upon the administration of kisspeptin10,but the expression decreased after interference with KISS1.Further experimentation involved treating hESC with inhibitors specific to Notch1,Akt,and Foxo1 separately,revealing a regulatory sequence of Notch1/Akt/Foxo1(P<0.05).In comparison to the NS group,NP mice administered with kisspeptin234 exhibited increased fetal absorption rates(P<0.001)and decreased expression of IGFBP1,Notch1,Akt,and Foxo1(P<0.05).Conversely,RSA mice administered with kisspeptin10 demonstrated decreased fetal absorption rates(P<0.001)and increased expression levels of the aforementioned molecules(P<0.05).Conclusion It is suggested that kisspeptin might exert its regulatory influence on the process of decidualization through the modulation of the Notch1/Akt/Foxo1 signaling cascade.A down-regulation of the expression levels of kisspeptin could result in suboptimal decidualization,which in turn might contribute to the development or progression of RSA.

Objective To investigate the current status of hepatitis B virus (HBV) infection among hospitalized patients aged 1-18 years, as well as the status of immunity after hepatitis B vaccination. Methods Related data were collected from the patients aged 1-18 years who were hospitalized in Henan Provincial People's Hospital from July 2020 to July 2021, including serological markers for hepatitis B (HBsAg, anti-HBs, HBeAg, anti-HBe, and anti-HBc) and hepatitis B vaccination. The epidemiological situation of HBV infection was analyzed, as well as the immune effect after vaccination. The trend chi-square test was used for trend analysis. Results A total of 10 658 hospitalized patients were collected, among whom there were 6 372 male patients (59.79%) and 4 286 female patients (40.21%). In this population, the patients with positive HBsAg accounted for 0.28% (30/10 658), with a relatively high proportion of 0.68% and 0.62%, respectively, in the 17-and 18-year age groups; the patients with positive anti-HBs accounted for 51.82% (5 523/10 658), with a relatively high proportion of > 63% in the 1-4 years age groups, and there was a reduction in the proportion of patients with positive anti-HBs (fluctuating around 40%) in the 5-18 years age groups. With the increase in age, the positive rate of anti-HBs tended to decrease in both male and female patients (male: χ 2 =8.217, P =0.004; female: χ 2 =10.048, P =0.002). Conclusion Based on the data of hospitalized patients, HBV infection in the population aged 1-18 years in Henan Province has the characteristics of low prevalence rate and high immunity, and the reduction in the proportion of patients with positive anti-HBs at more than five years after vaccination should be taken seriously in this region.

Shaoyaotang is composed of Cptidis Rhizoma， Scutellariae Radix， Rhei Radix et Rhizoma， Paeoniae Radix Alba， Angelicae Sinensis Radix， Aucklandiae Radix， Arecae Semen， Cinnamomi Cortex and Glycyrrhizae Radix et Rhizoma， with the functions of clearing away heat， eliminating dampness， regulating Qi and activating blood. Thus， it is proposed as the main formula for the treatment of dampness-heat dysentery by later generations of doctors. In modern clinical application， in addition to original Shaoyaotang， its modified formulas are also used for the treatment of ulcerative colitis， and can be used in combination with other prescriptions （such as Tongxie Yaofang， Pulsatilla Soup， Shenling Baizhu San）， western medicine （such as mesalazine， sulfasalazine， Infliximab）， traditional Chinese medicine （TCM） acupuncture or moxibustion and other characteristic therapies. Clinical efficacy results indicate that Shaoyaotang and its modified formulas can significantly lower Mayo Endoscopic Score （MES）， Baron score， TCM syndrome score and other disease scores， and improve patients’ intestinal symptoms， with few side effects. Experimental pharmacological studies reveal that Shaoyaotang can inhibit tumor necrosis factor-α （TNF-α）， nuclear transcription factor-κB （NF-κB）， interleukin-1β （IL-1β） and other pro-inflammatory factors to up regulate the expression of anti-inflammatory factors such as interleukin-10 （IL-10）， thereby reducing the inflammatory response. The formula could also reduce apoptosis by regulating inflammatory signaling pathway and blocking the chain reaction， and repair abnormal immune barrier by balancing immune axis and regulating immune proteins. Additionally， it could adjust the balance of intestinal flora， promote intestinal epithelial cell regeneration and improve mucosal permeability， so as to restore the balance of intestinal environment and thus treat ulcerative colitis. Its monomers baicalin， paeoniflorin， and berberine have anti-inflammatory， antibacterial， metabolism-regulating and other effects. This paper systematically reviewed the clinical and basic research progress of Shaoyaotang in the treatment of ulcerative colitis.
