Finally, the prospect of the application of liquid crystal emulsification technology in functional cosmetics is presented, to provide useful references for those engaged in the research of liquid crystal emulsification technology-related functional cosmetics.

Objective To compare the influence between self-monitoring of blood gluocose(SMBG)combined with digital diabetes management and traditional management mode on the related clinical indexes in the patients with type 2 diabetes mellitus(T2DM).Methods A total of 100 patients with T2DM treated in the endocrinology and metabolism outpatient department of this hospital from January 2022 to June 2022 and meeting the inclusion criteria of this study were successively included.They were divided into the experimental group and control group.The experimental group was managed by SMBG combined with digital diabetes man-agement mode,while the control group adopted the traditional management mode,the outpatient clinic follow up once a month.After 6 months of follow-up,fasting blood glucose,glycosylated hemoglobin(HbA1c),low density lipoprotein cholesterol(LDL-C)and urinary microalbumin/creatinine ratio(UACR)were compared between the two groups.Results The FBG,HbA1c,LDL-C,and UACR of the experimental group decreased after intervention when compared with baseline.Compared with the control group,the FBG[8.7(7.7,9.2)mmol/L vs.10.8(8.8,12.7)mmol/L,Z=-4.660,P＜0.001],HbA1c[6.3％(5.3,7.8)％vs.8.5％(7.2,10.0)％,Z=-5.130,P＜0.001],LDL-C[2.6(1.8,3.1)mmol/L vs.3.3(2.6,4.0)mmol/L,Z=-4.112,P＜0.001],UACR[16.1(3.5,46.5)mg/g vs.58.4(11.9,108.0)mg/g,Z=-2.220,P=0.026]for patients in the expriemental group after intervention were significantly decreased.Conclusion SMBG combined with digital diabetes management model can significantly improve the clinical indicators of patients.

Objective:To study the distribution and changes of dopamine transporter (DAT) in guinea pig eyes under different light patterns.Methods:Thirty-six 3-week-old white ordinary-grade guinea pigs were randomly selected and divided into groups of 10 000 lx, 5 000 lx, and 500 lx, with 12 guinea pigs in each group exposed to strong light, medium strong light, and normal light, respectively.Each group was randomly divided into 3 subgroups, with 4 guinea pigs in each subgroup.The 3 subgroups of 500 lx group received light exposure for 5, 20, and 40 minutes, respectively.The 3 subgroups of 5 000 lx group received light exposure for 2, 4, and 40 minutes, respectively.The 3 subgroups of 10 000 lx group received light exposure for 2, 5, and 20 minutes, respectively.After light treatment, each group of guinea pigs was injected with 99mTc-TRODAT-1 for SPECT DAT imaging, and image data were collected by Micro-SPECT.The region of interest (ROI) of guinea pig retinas was analyzed using Micro-CT software.The counts of ROI were expressed as Sum, which reflected the relative distribution or density of DAT.The DAT density between experimental and control eyes of guinea pigs after light exposure, the differences in DAT density between guinea pig eyes under different light intensities, the differences in DAT density between guinea pig eyes after different light durations, and the cumulative and interactive effects of light intensity and light duration on DAT aggregation in guinea pigs were compared.Another 3 guinea pigs were selected, and after light exposure, the 3 guinea pigs' eyes underwent continuous image acquisition for 6 hours at 20-minute intervals, and 18 images per guinea pig were acquired to analyze the trend of DAT density in guinea pig eyes over time.This study was approved by the Ethics Committee of Shanghai General Hospital (No.2020SQ196). Results:The DAT density (Sum value) of experimental eyes at 500, 5 000, and 10 000 lx were 5 598.97±3 159.38, 8 636.78±2 503.16, and 7 407.39±2 053.41, respectively, significantly higher than 4 388.89±2 902.90, 5 981.92±3 057.44, and 5 091.32±2 039.36 of control eyes ( t=5.31, 4.69, 11.80; all at P<0.001). At 500 lx, there was a statistically significant difference in DAT density between the experimental and control eyes of guinea pigs at different light exposure durations ( F=14.01, P<0.01), while no significant difference was found at other light intensities at different light exposure durations (both at P>0.05). When the light exposure time was 5 minutes, the difference in DAT density between the experimental and control eyes of guinea pigs was significantly greater in the 10 000 lx group than in the 500 lx group ( t=-13.22, P<0.001). There was no statistically significant difference between different groups at other light exposure durations (all at P>0.05). No cumulative or interactive effects of light intensity and light duration were found on the differences in DAT density (all at P>0.05). Continuous scanning after illumination showed that DAT density in guinea pig retinas first increased to a peak over time and then gradually returned to normal values. Conclusions:Light, even under moderate or normal light levels, can cause an increase in the secretion of DAT in the retina and stimulate the production of DAT.Light intensity and duration have no cumulative or interactive effects on the distribution and density of retinal DAT.

Recent studies have shown that Gal-9 is highly expressed in the liver and can help to maintain intrahepatic immune homeostasis and perform biological functions in various liver diseases. This article reviews the immunomodulatory functions of Gal-9 and its role in different liver diseases. Studies have shown that Gal-9 has important biological functions in different liver diseases through multiple pathways. Research on the specific immunomodulatory mechanisms and functions of Gal-9 may help to discover the therapeutic role of Gal-9 in liver diseases.

Objective To investigate the effects of miR-4531/CX3CL1 signaling pathway on the vascular injury in preeclampsia, and to search possible targets for early diagnosis and prevention of preeclampsia. Methods Placental tissue samples were obtained from 10 patients with late-onset preeclampsia and 10 normal pregnant women in the Obstetrics and Gynecology Department of Minhang Hospital, Fudan University from October 2021 to December 2022. The levels of miR-4531 and CX3CL1 were evaluated by qRT-PCR. Cell transfection was performed by lipofectamine 2000 in vitro. The binding relationship between miR-4531 and CX3CL1 was determined by luciferase reporter assay. The apoptosis of neutrophils, the migration, repair, colony formation and cell-free DNA (cfDNA) release of human umbilical vein endothelial cells (HUVECs) were detected. Results MiR-4531 was significantly downregulated, and CX3CL1 was upregulated in placental tissues of preeclampsia patients (P＜0.05). Luciferase report assay confirmed the direct binding relationship between miR-4531 and CX3CL1. Upregulation of miR-4531significantly promoted the migration, proliferation, repair, and inhibited cfDNA release of HUVECs and neutrophils apoptosis in medium under hypoxic condition (P＜0.05). However, downregulation of miR-4531 obviously inhibited the proliferation, migration, repair, and enhanced cfDNA release of HUVECs and neutrophils apoptosis in medium under hypoxic condition (P＜0.05). Conclusions The miR-4531is downregulated in placental tissues of preeclampsia parients and is a potential therapeutic target for preeclampsia. It might cause endothelial damage and an abnormal hypercoagulable state under hypoxic condition by targeting and regulating the CX3CL1 pathway.

【Objective】 To study the molecular mechanism of 95 samples of serological ABO subtypes. 【Methods】 A total of 95 samples with discrepancy between forward and reverse blood grouping were subjected to serological confirmation, and genotyped by polymerase chain reaction with sequence-specific primers (PCR-SSP). For those subtype alleles could not be detected by PCR-SSP, ABO gene exon 1-7 sequencing and gene single strand sequencing were performed successively to determine the mutation site and the gene location. 【Results】 A total of 34 ABO alleles were detected in 95 samples. Five common ABO alleles (ABO^*A1.01, ABO^*A1.02, ABO^*B.01, ABO^*O.01.01 and ABO^*O.01.02) and 29 rare ABO alleles were identified, including 16 named alleles by ISBT (ABO^*A2.01, ABO^*A2.05, ABO^*A2.13, ABO^*A3.07, ABO^*AW.37, ABO^*AEL.05, ABO^*B3.01, ABO^*B3.05, ABO^*BW.03, ABO^*BW.07, ABO^*BW.27, ABO^*BEL.03, ABO^*cisAB.01, ABO^*cisAB.05, ABO^*BA.02, ABO^*BA.04) and 5 named alleles by dbRBC(A223, B309, Bw37, Bel09, Bw40)and eight unnamed alleles [ABO^*B.01+ 978C>A, ABO^*A1.02+ 248A>T, ABO^*B.01+ 125dupT, ABO^*B.01+ (98+ 1G>A), ABO^*A1.02/ABO^*B.01+ 1A>G, ABO^*A1.02/ABO^*O.01.01+ 28G>T, ABO^*A1.02/ABO^*B.01+ 538C>T, ABO^*A1.02/ABO^*O.01.01+ 797insT] .The last four samples could not be verified by single strand because of insufficient samples. In 95 samples, 76 samples (21 named alleles of ISBT and dbRBC) were identified by PCR-SSP, and the remaining 19 samples were identified by exon 1-7 sequencing of ABO gene, of which 8 were identified as unnamed alleles, and the remaining 11 samples were not identified as subtype alleles. 【Conclusion】 The molecular genetic mechanism of 95 serological ABO subtypes was revealed, and 8 rare novel alleles were identified. The detection of ambiguous blood groups is influenced by factors such as patient pathology and physiology, therefore the combination of serological testing and genetic testing is suggested for the identification of ABO subtype.

With the increasing proportion of human papilloma virus(HPV)infection in the pathogenic factors of oro-pharyngeal cancer,a series of changes have occurred in the surgical treatment.While the treatment mode has been im-proved,there are still many problems,including the inconsistency between diagnosis and treatment modes,the lack of popularization of reconstruction technology,the imperfect post-treatment rehabilitation system,and the lack of effective preventive measures.Especially in terms of treatment mode for early oropharyngeal cancer,there is no unified conclu-sion whether it is surgery alone or radiotherapy alone,and whether robotic minimally invasive surgery has better func-tional protection than radiotherapy.For advanced oropharyngeal cancer,there is greater controversy over the treatment mode.It is still unclear whether to adopt a non-surgical treatment mode of synchronous chemoradiotherapy or induction chemotherapy combined with synchronous chemoradiotherapy,or a treatment mode of surgery combined with postopera-tive chemoradiotherapy.In order to standardize the surgical treatment of oropharyngeal cancer in China and clarify the indications for surgical treatment of oropharyngeal cancer,this expert consensus,based on the characteristics and treat-ment status of oropharyngeal cancer in China and combined with the international latest theories and practices,forms consensus opinions in multiple aspects of preoperative evaluation,surgical indication determination,primary tumor re-section,neck lymph node dissection,postoperative defect repair,postoperative complication management prognosis and follow-up of oropharyngeal cancer patients.The key points include:① Before the treatment of oropharyngeal cancer,the expression of P16 protein should be detected to clarify HPV status;② Perform enhanced magnetic resonance imaging of the maxillofacial region before surgery to evaluate the invasion of oropharyngeal cancer and guide precise surgical resec-tion of oropharyngeal cancer.Evaluating mouth opening and airway status is crucial for surgical approach decisions and postoperative risk prediction;③ For oropharyngeal cancer patients who have to undergo major surgery and cannot eat for one to two months,it is recommended to undergo percutaneous endoscopic gastrostomy before surgery to effectively improve their nutritional intake during treatment;④ Early-stage oropharyngeal cancer patients may opt for either sur-gery alone or radiation therapy alone.For intermediate and advanced stages,HPV-related oropharyngeal cancer general-ly prioritizes radiation therapy,with concurrent chemotherapy considered based on tumor staging.Surgical treatment is recommended as the first choice for HPV unrelated oropharyngeal squamous cell carcinoma(including primary and re-current)and recurrent HPV related oropharyngeal squamous cell carcinoma after radiotherapy and chemotherapy;⑤ For primary exogenous T1-2 oropharyngeal cancer,direct surgery through the oral approach or da Vinci robotic sur-gery is preferred.For T3-4 patients with advanced oropharyngeal cancer,it is recommended to use temporary mandibu-lectomy approach and lateral pharyngotomy approach for surgery as appropriate;⑥ For cT1-2N0 oropharyngeal cancer patients with tumor invasion depth＞3 mm and cT3-4N0 HPV unrelated oropharyngeal cancer patients,selective neck dissection of levels ⅠB to Ⅳ is recommended.For cN+HPV unrelated oropharyngeal cancer patients,therapeutic neck dissection in regions Ⅰ-Ⅴ is advised;⑦ If PET-CT scan at 12 or more weeks after completion of radiation shows intense FDG uptake in any node,or imaging suggests continuous enlargement of lymph nodes,the patient should undergo neck dissection;⑧ For patients with suspected extracapsular invasion preoperatively,lymph node dissection should include removal of surrounding muscle and adipose connective tissue;⑨ The reconstruction of oropharyngeal cancer defects should follow the principle of reconstruction steps,with priority given to adjacent flaps,followed by distal pedicled flaps,and finally free flaps.The anterolateral thigh flap with abundant tissue can be used as the preferred flap for large-scale postoperative defects.

ObjectiveTo identify immunogenic cell death （ICD）-related genes in hepatocellular carcinoma （HCC）， and to establish a scoring model based on these genes for predicting the prognosis and tumor microenvironment characteristics of HCC. MethodsThe Cancer Genome Atlas database was used to obtain HCC datasets， and heatmaps were used to display the expression of 57 ICD-related genes in HCC. A cluster analysis was conducted based on the expression of ICD-related genes， and two ICD subtypes （low and high ICD expression groups） were analyzed in terms of gene ontology enrichment analysis， Kyoto Encyclopedia of Genes and Genomes （KEGG） enrichment analysis， somatic mutation， and immune cell infiltration. The LASSO Cox regression risk model was constructed to evaluate its clinical application value， and a nomogram model was established to predict the 1-， 3-， and 5-year survival rates of patients. In addition， qRT-PCR was used to validate the expression levels of key genes in the model. The independent-samples t test was used for comparison between two groups， and the univariate and multivariate Cox regression analyses were used to determine prognostic factors among clinicopathological features. The Kaplan-Meier survival curve was used for prognostic analysis， and the Spearman rank correlation test was used for correlation analysis. ResultsThe low ICD expression group had a poorer prognosis， while the high ICD expression group had relatively favorable clinical outcomes （P=0.004）. Further analysis showed that the high ICD expression group was associated with an immune-active microenvironment， and the genes were mainly enriched in immune-related pathways such as immunoglobulin receptor binding， hematopoietic cell lineage， and B cell receptor. The results of somatic mutation analysis showed that the high ICD expression group had higher expression levels of CD274， CTLA4， HAVCR2， TIGIT， PDCD1， and PDCD1LG2 （all P<0.05）. A risk prediction model was established using 8 ICD-related genes， i.e.， HSP90AA1， ATG5， BAX， PPIA， HSPA4， TLR2， TREM1， and LY96， and this model showed a good predictive value across different clinical characteristics. The univariate and multivariate Cox regression analyses showed that age and risk score were independent prognostic factors for overall survival in the training set （both P<0.05）. The results of qRT-PCR showed that the relative expression levels of HSPA4 and REM1 in HCC tumor samples were significantly higher than those in adjacent tissue samples （both P<0.001）. For the patients with an increase in ICD risk score， the ICD risk score was negatively correlated with γδT cells （r=-0.29， P<0.05）， plasma cells （r=-0.3， P<0.05）， and CD8⁺T lymphocytes （r=-0.37， P<0.05） and was positively correlated with memory B cells （r=0.38， P<0.05）， resting dendritic cells （r=0.47， P<0.05）， and M0 macrophages （r=0.49， P<0.05）. ConclusionThis study identifies the ICD-related genes that are associated with the prognosis of HCC， which provides insights into the immune characteristics of different ICD expression profiles. The risk model and the nomogram model established in this study have a significant value for predicting the prognosis of HCC patients and guiding immunotherapy for HCC patients.

Objective To investigate the effects of electroacupuncture on the intestinal NIMA-related kinase 7(NEK7)/NOD-like receptor thermal protein domain associated protein 3(NLRP3)signaling pathway in mice with Parkinson's disease.Methods According to the randomized number table method,36 C57BL/6 mice were randomly divided into the control group,the model group,and the electroacupuncture group,with 12 mice per group.The Parkinson's disease mouse model was established by gavage of rotenone solution(10 mg/kg)for 28 d.After molding,the electroacupuncture group was stimulated with"Fengfu"(DU17),"Taichong"(LR3),and"Zusanli"(ST36)for 14 d,while the control group and the model group were only treated with immobilization.The motor ability of mice was detected by pole climbing test and hindlimb rating score,the positive expressions of nigral tyrosine hydroxylase(TH)and colon occludin were detected by immunohistochemistry,the histological morphology of colon was observed by hematoxylin-eosin staining,and Western blotting was used to detect the protein expressions of NEK7,NLRP3,Caspase-1,and interleukin-1β(IL-1β).Results Compared with the control group,mice in the model group had lower score on the pole climbing test and a higher hindlimb rating score(P＜0.01);the average optical densities of nigral TH and colon occludin were decreased(P＜0.01);significant inflammatory infiltration was observed in the colonic tissue,and the muscularis propria was thinned;and the protein expressions of NEK7,NLRP3,Caspase-1,and IL-1β in the colonic tissue were elevated(P＜0.01).Compared with the model group,mice in the electroacupuncture group had higher score on the pole climbing test and a lower hindlimb rating score(P＜0.01);the average optical densities of nigral TH and colon occludin were increased(P＜0.01);the degree of inflammatory infiltration of colonic tissues decreased,and the muscularis propria was thickened;and the protein expressions of NEK7,NLRP3,Caspase-1,and IL-1β of colonic tissues were decreased(P＜0.01).Conclusion Electroacupuncture at"Fengfu"(DU17),"Taichong"(LR3),and"Zusanli"(ST36)can improve motor functional impairments in mice with Parkinson's disease,and the mechanism may be through the inhibition of intestinal NEK7/NLRP3 pathway,improving the intestinal barrier damage,relieving the intestinal inflammation,and improving the dopaminergic neuron injury.

Objective:To explore the feasibility and application value of indocyanine green(ICG)lymph node tracer in clinical early stage cervical cancer staging surgery.Methods:A retrospective analysis was performed on 31 patients with early clinical stage(ⅠA1-ⅡA1)cervical cancer who underwent laparoscopic radical hysterectomy,pelvic lymph node resection and para-aortic lymph node sampling were selected as the study subjects in Sichuan Provincial Maternal and Child Health Care Hospital from April 1,2022 to July 31,2023.They were divided into the ICG fluorescence tracer group(ICG group,17 cases)and the conventional surgery group(control group,14 ca-ses)based on whether ICG was injected or not.The resected lymph nodes were classified and submitted for ex-amination according to location and whether they presented visualization.The method of contingency coefficient was used to analyze the correlations between lymph node visualization patterns and lymph node metastasis and clinicopathological characteristics,and the perioperative data of the two groups were compared.Results:①The postoperative stage of 8 patients(25.8％)(4 in each group)were improved compared with the preoperative clini-cal stage.The number of resected lymph nodes in the ICG group was less than that in the control group(18±9 nodes/person vs.26±11 nodes/person,P＜0.05).There were no statistically significant differences in operation time,intraoperative blood loss,postoperative FIGO(2018)staging,lymph node metastasis rate,and positive rate of resected lymph nodes between the two groups(P＞0.05).②The visualization rate in the ICG group was 64.71％(11/17).There was no statistically significant difference in the positive rate between the visualized and non-visualized lymph nodes(P＞0.05).There was a significant correlation between lymph node visualization and lymph node metastasis(C=0.707,P＜0.05),and a significant correlation was found between lymph node visual-ization and lymph node metastasis in the same patient(C=0.557,P＜0.05).Conclusions:The rate of lymph node metastasis in clinical early stage cervical cancer is low.ICG fluorescence visualization can trace lymph nodes and predict the risk of metastasis.By only resecting the visualized lymph nodes under the guidance of ICG tracer,the lymph node metastasis status of early-stage cervical cancer can be fully evaluated,which is worthy of further research.
