Objective: To analyze the trends, gender, and age differences in the incidence of lip and oral cavity cancer in Chinese population from 1990 to 2021 and predict future incidence trends, providing a scientific basis for disease prevention and public health policy. Methods: Incidence data of lip and oral cavity cancer in Chinese population from the Global Burden of Disease (GBD) database from 1990 to 2021 were analyzed. The Joinpoint regression model was used to assess temporal trends, the age-period-cohort model was used to evaluate the independent effects of age, period, and cohort, and the Bayesian age-period-cohort model (BAPC) model was used to predict incidence trends from 2022 to 2044. Results: From 1990 to 2021, the age-standardized incidence rate of lip and oral cavity cancer in Chinese population increased from 2.39/100 000 to 3.76/100 000, and the crude incidence rate rose from 1.71/100 000 to 4.85/100 000. The incidence rate in males was higher and increased more rapidly than in females. Higher incidence rates were prevalent among older populations, a rapid increase in incidence rates occurred during 2003 to 2012, and earlier birth cohorts showed overall higher risks. BAPC predictions indicated a continued rise in incidence from 2022 to 2044. During this period, male incidence stabilized while female incidence increased at a relatively faster rate. Conclusion The incidence of lip and oral cavity cancer in Chinese population has revealed a continuous upward trend, particularly among males and older populations. Future prevention strategies should focus on these high-risk populations.

Chemotherapy-induced peripheral neurotoxicity (CIPN) is a severe dose-limiting adverse event of chemotherapy. Presently, the mechanism underlying the induction of CIPN remains unclear, and no effective treatment is available. In this study, through metabolomics analyses, we found that nab-paclitaxel therapy markedly increased serum serotonin [5-hydroxtryptamine (5-HT)] levels in both cancer patients and mice compared to the respective controls. Furthermore, nab-paclitaxel-treated enterochromaffin (EC) cells showed increased 5-HT synthesis, and serotonin-treated Schwann cells showed damage, as indicated by the activation of CREB3L3/MMP3/FAS signaling. Venlafaxine, an inhibitor of serotonin and norepinephrine reuptake, was found to protect against nerve injury by suppressing the activation of CREB3L3/MMP3/FAS signaling in Schwann cells. Remarkably, venlafaxine was found to significantly alleviate nab-paclitaxel-induced CIPN in patients without affecting the clinical efficacy of chemotherapy. In summary, our study reveals that EC cell-derived 5-HT plays a critical role in nab-paclitaxel-related neurotoxic lesions, and venlafaxine co-administration represents a novel approach to treating chronic cumulative neurotoxicity commonly reported in nab-paclitaxel-based chemotherapy.

Curcumae Rhizoma, derived from the rhizome of Curcuma phaeocaulis, Curcuma kwangsiensis and Curcuma wenyujin, was called Ezhu in China. In the past, Curcumae Rhizoma extracts were obtained through water decoction or alternative methods, which showed significant anti-cancer effects. However, the mixed extracts contain various compound components of Curcumae Rhizoma, leading to an ambiguous mechanism of action for Curcumae Rhizoma extracts anti-cancer. Contemporary researchers have extracted the chemical components of Curcumae Rhizoma separately for experimental verification of its active ingredients in the anti-cancer field. Numerous studies demonstrated that curcumol, germacrone, β-elemene, and curcumin in Curcumae Rhizoma extracts have significant governing effects in anti-cancer activities. Pharmacological studies have shown that Curcumae Rhizoma suppresses cancer cell proliferation, invasion, and migration, triggering apoptosis and regulating cellular autophagy to achieve anticancer effects. Here, we summarized the research progress of Curcumae Rhizoma on anti-cancer effects from 2013 to 2022, aiming to explore the deeper molecular mechanisms of Curcumae Rhizoma's active components in cancer treatment.

Refinement and standardisation of the management of clinical diagnostic and treatment operations is a key aspect of achieving high-quality development in hospitals.By analysing the management status quo of clinical diagnosis and treatment operations in hospitals,it combed the problems existing in this field.Based on the closed-loop management model,it proposed measures and recommendations to promote the continuous optimisation of the management of clinical diagnostic operations in hospitals.Hospitals should establish hospital-level operation catalog and conduct classified management,authorize operators and dynamically adjust them,carry out operation quality management,pay attention to information management of operation management,and combine operation management with physician performance management.

Objective To explore the acupoint selection law and staged acupuncture prescriptions in the treatment of post-stroke dysphagia using data mining technology.Methods Clinical research literature about acupuncture treatment of post-stroke dysphagia was retrieved from CNKI,Wanfang Data,VIP,SinoMed,PubMed,Embase,Cochrane Library from January 1,2004 to October 1,2024.Prescription information was organized and summarized,and was entered into the database.Descriptive analysis,association rule analysis,complex network analysis and clustering analysis on prescription acupoints were conducted with Excel 2021,SPSS Modeler 18.0 and SPSS 26.0 softwares.Results A total of 306 articles were included,including 328 acupuncture prescriptions involving 118 acupoints,with a cumulative frequency of 1 541 times.The core acupoints were Lianquan,Fengchi,Yuye,Jinjin,Yifeng,Jialianquan,Fengfu and Wangu.The main meridians were Conception Vessel,gallbladder meridian,Governor Vessel and stomach meridian.The distribution was concentrated in the head,face and neck,and the use of intersection acupoints were the most.Association rule analysis showed that Lianquan-Fengchi,Lianquan-Jinjin-Yuye had the highest degree of support for association rules,and the clustering analysis showed 4 categories such as Jialianquan-Baihui-Fengfu.The analysis obtained corresponding acupuncture prescriptions for oral stage,pharyngeal stage and esophageal stage of dysphagia.Conclusion Acupuncture treatment of post-stroke dysphagia is mainly based on local acupoint and acupoint along meridians,mostly using intersection acupoints,combined with distal acupoints,and selecting the corresponding acupoints in different periods,which can improve the clinical efficacy.

Objective:To investigate the influence of inner cell mass and trophectoderm cytoplasmic strings during blastocyst expan-sion on embryonic development and pregnancy outcome.Methods:A retrospective cohort analysis was performed for the clinical data of patients who received pre-implantation genetic testing for aneuploidy(PGT-A)and underwent single blastocyst transplantation in our hospital from June 2019 to December 2021.A total of 530 patients were enrolled,and genetic testing was performed for 2132 blasto-cysts.According to the presence or absence of cytoplasmic strings during blastocyst expansion,the blastocysts were divided into cyto-plasmic strings(+)group with 534 blastocysts and cytoplasmic strings(-)group with 1598 blastocysts,and quality and PGT-A results were compared between the two groups.After the transfer of euploid blastocysts,pregnancy outcome was compared between the 115 blastocysts with cytoplasmic strings and the 415 blastocysts without cytoplasmic strings.Results:The rates of cytoplasmic strings(+)in the high-,average-,and low-quality blastocyst groups were 30.19%,24.62%,and 12.63%,respectively.The correlation analysis showed a correlation coefficient of-0.115(P<0.001)between embryo quality and the rate of cytoplasmic strings(+).There was no sig-nificant difference in euploidy rate between the two groups(45.3%vs.44.6%).There were no significant differences between the euploid blastocysts with cytoplasmic strings and those without cytoplasmic strings in implantation rate(72.17%vs.66.02%,P=0.213),miscarriage rate(14.46%vs.12.77%,P=0.691),and live birth rate(61.74%vs.57.59%,P=0.424).Conclusion:The presence of cyto-plasmic strings is associated with the morphological quality of blas-tocysts,while it has no impact on embryo ploidy or clinical outcome after euploid embryo transfer.Further research is needed to confirm the impact of cytoplasmic strings on embryonic development.

Objective To explore the effects of sigma-1 receptor(Sig-1R)on brain function in rats after cardiopulmo-nary resuscitation and its protective role in brain injury.Methods Rats were randomly assigned to four groups with 20 in each:sham-operated control(sham group),6-hour post-resuscitation(PR 6 h group),12-hour post-resuscitation(PR 12 h group)and 24-hour post-resuscitation(PR 24 h group).In the latter three groups,cardiac arrest was induced by as-phyxiation,and cardiopulmonary resuscitation was performed 6 minutes after cardiac arrest.The rats were scored for neu-rological deficits at 6,12 and 24 hrs after resuscitation,respectively;after that,the rats were executed,and the expres-sion of Sig-1R protein,mitochondrial function index,and endoplasmic reticulum stress index apoptosis index were detec-ted by Western blot and immunohistochemistry.The correlation between Sig-1R and mitochondrial,endoplasmic reticulum stress and apoptosis indexes was evaluated.Results Compared with the sham-operated group,the rats in test group showed a gradual decrease in neurological deficit scores,Sig-1R protein expression,brain tissue adenosine triphos-phate(ATP)concentration and mitochondrial membrane potential(MMP)levels at 6,12,and 24 hrs of PR(P＜0.05);CHOP protein,activated cleaved caspase-12 and cleaved caspase-3 protein expression were consistently elevated(P＜0.05).In addition,Sig-1R was negatively correlated with brain tissue endoplasmic reticulum stress and apoptosis(P＜0.05)but positively correlated with mitochondrial membrane potential level(P＜0.05).Conclusions Sig-1R ex-pression in rat brain tissue correlates with brain injury after cardiopulmonary resuscitation and potential mechanism seems to be neuronal protection through modulating mitochondrial function and endoplasmic reticulum stress.

Diabetic macular ischemia(DMI), playing key roles behind the progression of diabetic retinopathy(DR), is one of the causes of vision loss. Its pathophysiological process is complex, involving vascular structure changes, hemodynamic abnormalities, and many other aspects. Traditional inspection methods often make it difficult to accurately capture subtle changes in DMI. In turn, optical coherence tomography angiography(OCTA)has opened a pathway to the diagnosis and treatment of DMI, which not only has the advantages of non-invasive, safe and rapid imaging, but also furnishes high-resolution retinal vascular images to provide qualitative and quantitative descriptions of DMI. OCTA can visually show the morphological and structural changes of blood vessels in the macular region, as well as reveal the characteristics of pathological changes in the superficial and deep capillary plexus of DMI patients, which provides a deeper understanding of DMI and a new treatment option of diabetic eye disease.

Objective To elucidate the role of let-7 in the pathogenesis of oral squamous cell carcinoma(OSCC)and its underlying molecular mechanism.Methods The expression of let-7 in human oral keratinocyte(HOK),OSCC tissues,and OSCC cells(CAL-27,SCC-25,and SCC-9)was detected by quantitative real-time PCR.Colony formation,scratch,Transwell,and flow cytometry assays were used to examine the effects of let-7 on the proliferation,migration,invasion,and apoptosis of SCC-25 cells.Western blotting was used to detect the expression of Wnt and β-catenin proteins.The correlation between let-7 expression and the clinicopathological cha-racteristics and prognosis of OSCC patients was analyzed.Results let-7 was downregulated in OSCC tissues and cells.let-7 over-expression effectively inhibited the proliferation,migration,and invasion of SCC-25 cells while promoting apoptosis by suppressing acti-vation of the Wnt/β-catenin pathway.let-7 expression was closely associated with tumor stage,lymph node metastasis,and patient survival status.Patients with low let-7 expression exhibited lower overall survival rate.Conclusion let-7 targets and regulates the Wnt/β-catenin pathway,thereby inhibiting proliferation,migration,and invasion of OSCC cells while promoting apoptosis.

Background and Aims:Precise localization of lesions and optimization of the surgical approach are crucial in laparoscopic left hepatectomy.Traditional surgical techniques have certain limitations,whereas indocyanine green(ICG)fluorescence navigation can accurately delineate the boundaries of liver lesions.The Laennec's capsule approach aids in clearly exposing intrahepatic structures.This study was conducted to evaluate the clinical effectiveness of combining ICG fluorescence navigation with the Laennec's capsule approach in laparoscopic left hepatectomy.Methods:The clinical data of 44 liver cancer patients who underwent surgery at the Hepatobiliary Surgery Department of Xuanhan People's Hospital from January 2023 to November 2024 were retrospectively collected.Among them,22 patients underwent laparoscopic left hepatectomy with Pringle's maneuver for total hepatic inflow occlusion(control group),while the other 22 patients received laparoscopic left hepatectomy using ICG fluorescence navigation combined with the Laennec's capsule approach(observation group).The two groups were compared in terms of intraoperative surgical time,average blood loss,intraoperative transfusion rate,liver function on postoperative days(POD)1,3,and 7[total bilirubin(TBIL),aspartate aminotransferase(AST),alanine aminotransferase(ALT)],average length of hospital stay,gastrointestinal function recovery time,POD 1-6 drainage volume,incidence of postoperative complications,and short-term efficacy.Results:The observation group had significantly shorter average surgical time than the control group[(218.19±39.18)min vs.(245.23±44.36)min,P＜0.05]and less average blood loss[(320.44±78.62)mL vs.(456.37±88.16)mL,P＜0.05].The intraoperative transfusion rate between the two groups was not significantly different(13.64％vs.9.09％,P＞0.05).The observation group had significantly less postoperative drainage POD 1-6 than the control group[(431.19±152.18)mL vs.(528.23±184.36)mL,P＜0.05].The average hospital stay and gastrointestinal function recovery time were shorter in the observation group[(9.21±2.92)d vs.(12.72±3.24)d;(2.24±0.42)d vs.(3.35±0.53)d,both P＜0.05].Postoperative liver function tests(TBIL,AST,ALT)on days 1,3,and 7 were significantly lower in the observation group compared to the control group(all P＜0.05).The difference in the overall response rate between the two groups was not statistically significant(72.73％vs.77.27％,P＞0.05).No severe postoperative complications occurred in either group.Conclusion:The combination of ICG fluorescence navigation with the Laennec's capsule approach demonstrates favorable clinical outcomes in laparoscopic left hepatectomy and is worthy of clinical promotion.
