Objective:Laryngopharyngeal reflux disease refers to a series of symptoms and signs caused by gastroduodenal contents regurgitate into the upper respiratory, digestive tract above the upper esophageal sphincter. In recent years, with the deepening of the pathogenesis, the treatment plan of this disease is constantly updated and optimized, but there is still no gold standard for treatment. This paper summarizes the treatment of pharyngeal reflux disease and proposes that based on proton pump inhibitors, potassium competitive acid blockers and alginate can be used as alternative therapy for proton pump inhibitors. Meanwhile, the external upper esophageal sphincter pressure device has sufficient potential value to be concerned. Lifestyle change and dietary structure adjustment should be used as the basic treatment throughout. To provide directions for further treatment of the disease.

Objectives:To compare the efficacy of the combination of excimer laser coronary angioplasty(ELCA)and drug-coated balloon(DCB)for in-stent restenosis(ISR)and to evaluate the impact of neointimal tissue characteristics on treatment outcomes. Methods:A total of 96 ISR lesions from 86 patients who underwent optical coherence tomography(OCT)evaluation and DCB with or without ELCA treatment at The First Medical Center of Chinese PLA General Hospital from January 2019 to May 2023 were retrospectively analyzed.ISR lesions were divided into ELCA+DCB group(n=30)and DCB group(n=66).Additionally,ISR lesions were classified as homogeneous and non-heterogeneous patterns based on the OCT characteristics of the neointimal tissue,and the impact on acute lumen gains was compared between different ISR patterns.Acute lumen gain(ΔMLA)was defined as the changes in minimum lumen area before and after the intervention. Results:The ELCA+DCB group had a significantly greater ΔMLA than the DCB group([3.2±0.8]mm2 vs.[2.6±1.4]mm2,P=0.015).Among the ISR with a homogeneous pattern,the ΔMLA of the ELCA+DCB group was significantly greater than that of the DCB group([3.0±0.9]mm2 vs.[2.2±1.1]mm2,P=0.030).There was no significant difference in ΔMLA between the two ISR groups with the non-homogeneous pattern([3.4±0.7]mm2 vs.[3.2±1.5]mm2,P=0.533).There was no death,the rate of target lesion revascularization was similar between the patients with lesions receiving DCB treatment and patients receiving ELCA +DCB treatment(7.4%vs.4.2%,P＞0.05). Conclusions:The combination of ELCA and DCB is an effective strategy for treating ISR,which can achieve greater acute lumen gain compared to DCB treatment alone,especially for the treatment of homogenous ISR pattern characterized by OCT.

Objective To explore the predictive value and efficacy evaluation of plasma microRNA(miR)-132,miR-134 combined with miR-124 in patients with depression.Methods A total of 75 patients diagnosed with depression in the psychiatric department of the hospital from June 2021 to July 2023 were selected as the study group,and 75 healthy subjects who underwent physical examination in the hospital during the same pe-riod were selected as the control group.The relative expression levels of miR-132,miR-134 and miR-124 in plasma of the two groups were detected.The levels of miR-132,miR-124,miR-134,brain-derived neurotrophic factor(BDNF).inflammatory factors[interleukin(IL)-6,IL-18,tumor necrosis factor-a(TNF-a)]were com-pared between the two groups before and after 8 weeks of treatment.Multiple linear regression analysis was used to construct a joint prediction model.The application value of plasma miR-132,miR-134,miR-124 and combined prediction in the diagnosis of depression was evaluated by receiver operating characteristic(ROC)curve.Results The relative expression levels of miR-132 and miR-124 in plasma of the study group were sig-nificantly higher than those of the control group,with statistical significance(P＜0.05).The relative expres-sion level of miR-134 in the study group was significantly lower than that in the control group,and the differ-ence was statistically significant(P＜0.05).ROC curve analysis showed that the area under the curve of plas-ma miR-132,miR-134,miR-124 and combined prediction of depression were 0.858 8,0.851 9,0.763 1 and 0.971 4,respectively.Compared with 8 weeks before treatment,plasma miR-132,miR-124,IL-6,IL-18 and TNF-a levels were significantly down-regulated,while plasma miR-134 and BDNF levels were significantly up-regulated after 8 weeks of treatment.Conclusion miR-132,miR-134 and miR-124 are closely related to the oc-currence of depression,and the combination of the three can be used to predict and early diagnose depression patients and evaluate the drug efficacy of depression patients.

Objective:To reassess the prognostic value of minimal residual disease (MRD) and IKZF1 gene deletions in adults with B-cell acute lymphoblastic leukemia (B-ALL) who received pediatric-specific chemotherapy regimens during the Nanfang Hospital PDT-ALL-2016 trial.Methods:We retrospectively analyzed the prognosis of 149 adult patients with B-ALL who were admitted to Nanfang Hospital from January 2016 to September 2020. Prognostic factors were identified using Cox regression models.Results:The complete remission rate was 93.2% in 149 patients, with a 5-year overall survival (OS) rate of (54.3±5.0) % and a cumulative incidence of relapse (CIR) of (47.5±5.2) %. The Cox regression analysis revealed that MRD positivity at day 45 (MRD 3) after induction therapy was independently associated with relapse risk ( HR=2.535, 95% CI 1.122-5.728, P=0.025). Deletion of IKZF1 gene was independently associated with mortality risk ( HR=1.869, 95% CI 1.034-3.379, P=0.039). Based on MRD 3 and IKZF1 gene status, we categorized adult patients with B-ALL into the low-risk (MRD 3-negative and IKZF1 gene deletion-negative) and high-risk (MRD 3-positive and/or IKZF1 gene wild type) groups. The 5-year OS and CIR rates were (45.5±6.0) % vs (69.4±8.6) % ( P<0.001) and (61.6±8.3) % vs (25.5±6.5) % ( P<0.001), respectively, in the high-risk and low-risk groups, respectively. The multivariate analysis showed that the high-risk group was an independent risk factor for OS ( HR=3.937, 95% CI 1.975-7.850, P<0.001) and CIR ( HR=4.037, 95% CI 2.095-7.778, P<0.001) . Conclusion:The combined use of MRD and IKZF1 gene in prognostic stratification can improve clinical outcome prediction in adult patients with B-ALL, helping to guide their treatment.

Objective To investigate whether cisplatin induces tumor necrosis factor-α(TNF-α)secretion in human head and neck squamous cell carcinoma(HNSCC)cells to trigger RIP1/RIP3/MLKL-dependent necroptosis of the cells.Methods HNSCC cell lines HN4 and SCC4 treated with cisplatin(CDDP)or the combined treatment with CDDP and z-VAD-fmk(a caspase inhibitor)or Nec-1(a necroptosis inhibitor)for 24 h were examined for changes in cell viability using CCK8 assay and expressions of caspase-8 and necroptosis pathway proteins(RIP1/RIP3/MLKL)using Western blotting.The changes in migration of the cells were assessed with cell scratch assay,and the expressions of epithelial-mesenchymal transition(EMT)marker proteins N-cadherin,vimentin,and E-cadherin as well as the expressions of NF-κB(p65)and TNF-α were detected with Western blotting.Results The IC50 of cisplatin was 10 μg/mL in HN4 cells and 15 μg/mL in SCC4 cells.Cisplatin treatment significantly decreased the expressions of caspase-8,N-cadherin and vimentin and increased the expressions of E-cadherin,the necroptosis pathway proteins(RIP1/RIP3/MLKL),TNF-α,and NF-κB(p65),and these changes were obviously inhibited by treatment with Nec-1.Cisplatin stimulation also significantly lowered migration of the cells,and this inhibitory effect was strongly attenuated by Nec-1 treatment.Conclusion Cisplatin activates nuclear factor-κB signaling in HNSCCs to promote TNF-α autocrine and induce RIP1/RIP3/MLKL-dependent necroptosis,thus leading to inhibition of cell proliferation.

Severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)is the main pathogen that causes COVID-19,which is fast-mutating and highly transmissible.The infection has led to a global epidemic.As the main preventive and control measure,vaccination plays a critical role in fighting a-gainst COVID-19.Although a large number of epitope-based and mucosal vaccines have been stud-ied,few peptide epitope vaccines targeting the mucosa and their functional evaluation have been re-ported.In this study,we used SARS-CoV-2 structural protein M peptide epitope predicted by the IEDB database as an antigenic target to design the MS-3S gene containing 3 050 and 1 229 signal peptides and DCpep optimized for insertion into MS2 phage coat proteins.The expression plasmid pSIP:MS-3S was constructed by cloning the PCR fragments seamlessly and was transformed into Lactiplantibacillus plantarum 18 to obtain the recombinant bacterium LP18:MS-3S.Expression conditions such as induction time,inducer concentration,rotational speed and initial pH were opti-mized.The intranasal immunization experiments were performed to examine the vaccine efficacy.The results showed that the 916 bp-long target gene MS-3S modified and optimized was amplified and used to successfully construct the recombinant bacterial strain LP18:MS-3S.The optimal con-ditions for recombinant protein expression were obtained and verified by Western blot,flow cy-tometry,immunofluorescence and other detection methods.The optimal expression conditions were determined as follows:induction time was 4 h with 100 pg/L of SppIP as the optimal induction concentration.Antibody-specific for the epitope was verified by ELISA experiments in serum,alve-olar lavage fluid and fecal dilutions of mice.In summary,a recombinant bacterial strain expressing the epitope antigen of the SARS-CoV-2 M protein peptide was constructed.The obtained protein can induce the body to produce humoral and mucosal immunity,which lays the foundation for the development of a vaccine candidate for the mucosal immunity of COVID-19.

Objective:To explore the development and interaction between chronotype and depressive symp-toms among middle school students in Chongqing.Methods:A total of 1208 middle school students(613 in grade 7,595 in grade 10)were surveyed for three follow-ups at 6-month intervals.Periods T1-T3 represented baseline,6 months later,and 12 months later,respectively.Chronotype and depressive symptoms were measured by the Morn-ing and Evening Questionnaire-5(MEQ-5)and the Patient Health Questionnaire-9(PHQ-9).Analyses were per-formed using SPSS 26.0 and Mplus 8.3.Results:The MEQ-5 scores were lower in T1 than in T3,and the scores were lower in T2 than in T1 and T3(F=20.08,P＜0.001),suggesting a fluctuating trend of chronotype shifting to the Evening-type first after baseline and then to the Morning-type.The PHQ-9 scores exhibited a significant differ-ence among the three-time measurements(x2/df=9.77/2,P＜0.01).But pairwise comparisons did not yield any statistically significant findings(P＞0.05).The cross-lagged panel model showed that pathways of Ti MEQ-5 scores negatively predicted Ti+1 PHQ-9 scores(βTi-Ti+1=-0.12/-0.09,P＜0.05)and TiPHQ-9 scores nega-tively predicted Ti+1 MEQ-5 scores(βTi-Ti+1=-0.07/-0.11,P＜0.05).Conclusion:Chronotype and depressive symptoms show some changes in adolescents.The more inclined adolescents are to the Evening-type,the higher the likelihood of depressive symptoms occurring later.The more severe the depressive symptoms,the greater the likeli-hood of a subsequent shift to the Evening-type.

ObjectiveTo investigate the effect and mechanism of osthole on the proliferation and apoptosis in human intrahepatic cholangiocarcinoma HuCCT1 cells. MethodThe effect of 10， 20， 40， 80， and 120 μmol·L^-1 osthole on the proliferation of HuCCT1 cells was detected by the cell counting kit-8 （CCK-8）. A blank group， and low-， medium-， and high-dose osthole groups （16， 32， and 64 μmol·L^-1） were set up. The effect of osthole on cell clone formation rate was detected by colony formation assay. The effect of osthole on cell cycle and apoptosis was detected by flow cytometry. The effect of osthole on cell apoptotic morphology was detected by Hoechst 33342 fluorescent staining. The effect of osthole on cell cycle protein cyclin B₁， proliferating cell nuclear antigen （PCNA）， cysteine-aspartic acid protease （Caspase）-9， Caspase-3， cleaved Caspase-9， cleaved Caspase-3， cleaved poly（ADP-ribose） polymerase （cleaved PARP）， B-cell lymphoma-2 （Bcl-2）， phosphorylated protein kinase B （p-Akt）， phosphorylated mammalian target of rapamycin （p-mTOR）， and phosphorylated ribosomal protein S6 （p-RPS6） was detected by Western blot. ResultThe cell viability in the osthole group（40，80，120 μmol·L^-1） decreased （P<0.05，P<0.01）， with the half maximal inhibitory concentration （IC₅₀） of 63.8 μmol·L^-1 as compared with that in the blank group. Compared with the blank group， the osthole groups（32，64 μmol·L^-1）showed reduced clone formation rate （P<0.01）， increased number of cells in the G₂ phase （P<0.05，P<0.01）， decreased number of cells， increased pyknosis and fragmentation， increased apoptosis rate （P<0.05，P<0.01）， down-regulated expression of cyclin B₁， PCNA， Bcl-2， Caspase-3， Caspase-9， p-Akt， p-mTOR， and p-RPS6 （P<0.05，P<0.01）， and up-regulated expression of cleaved Caspase-3， cleaved Caspase-9， and cleaved PARP （P<0.05，P<0.01）. ConclusionOsthole can inhibit the proliferation and promote the apoptosis of HuCCT1 cells， and its mechanism may be related to the Akt/mTOR signaling pathway.
