Objective:To investigate the efficacy of anatomical resection (AR) in the early stages of treating solitary hepatocellular carcinoma (HCC) combined with liver cirrhosis with a diameter of ≤5 cm in comparison to different surgical methods of preferential hepatic parenchymal preservation (non-anatomical liver resection, NAR).Methods:The clinical data of 1 390 cases with solitary HCC combined with liver cirrhosis at an early stage who underwent liver resection at Mengchao Hepatobiliary Hospital of Fujian Medical University and six other medical centers from September 2013 to May 2019 were retrospectively analyzed. Patients were divided into the AR group (486 cases) and the NAR group (904 cases) and the wide surgical margin (WSM) group (745 cases) and the narrow surgical margin (NSM) group (645 cases) according to whether they received AR and the width of the surgical margin (1 cm). The basic information of the patients, preoperative evaluation index data, and postoperative follow-up (follow-up every 3 months) were collected. The Kaplan-Meier method was used to plot the survival curve.The log-rank test was used to compare the difference in survival between the two groups. The Cox proportional hazards regression model was used to analyze the factors affecting the prognosis. Propensity score matching (PSM) was applied to reduce intergroup bias.Results:The overall survival (OS) rates for all patients at 1, 3, and 5 years were 95.5%, 79.9%, and 63.5%, respectively. The recurrence-free survival (RFS) rates were 81.5%, 59.0%, and 43.7%, respectively. There was a statistically significant difference in RFS rate between the AR group and the NAR group prior to PSM, but no statistically significant difference in OS rate (RFS rate: 47.0% vs. 41.9%, P<0.05; OS rate: 64.4% vs. 62.9%, P>0.05). The postoperative RFS rate and OS rate were significantly superior in the WSM group than those of the NSM group (RFS rate: 47.8% vs. 37.2%, P<0.001; OS rate: 69.0% vs. 57.3%, P<0.001). There was no statistically significant difference in OS rate and RFS rate between the AR group and the NAR group following PSM (RFS: 46.3% vs. 45.1%, P>0.05; OS rate: 64.0% vs. 64.3%, P>0.05).The 5-year OS and RFS rates in the WSM group were 66.8% and 60.2%, respectively. The 5-year OS and RFS rates for the NSM group were 48.7% and 41.4%, respectively, with a statistically significant difference ( P<0.05). Cox multivariate analysis indicated that serum albumin, tumor diameter, microvascular invasion, and surgical margin were independent prognostic factors affecting OS and RFS. The Child-Pugh grade and satellite lesions were independent prognostic factors affecting OS. Conclusion:Anatomical liver resection is not an independent risk factor for prognosis, but the state of the resection margin determines the prognosis of patients with solitary HCC combined with cirrhosis. Therefore, hepatic resection margins should be prioritized in such patients.

Objective To explore the efficacy of negative pressure ureteral access sheath combined with disposable flexible ureteroscope(UAS+FRUS)in the treatment of renal calculi of 2-3 cm,so as to provide reference for the treatment.Methods A retrospective analysis was conducted on 130 cases of renal calculi of 2-3 cm treated with surgery in Xiamen Third Hospital during Sep.2021 and Sep.2023,including 68 cases with UAS+FRUS and 62 cases with super-mini percutaneous nephrolithotripsy(SMP).The perioperative indexes and stone-clearance rate(SFR)were compared between the two groups.Results All operations were successful.There were no statistically significant differences in the total SFR and incidence of complications(5.88％vs.9.67％)between the two groups 3 days(88.24％vs.90.32％)and 1 month(91.18％vs.93.55％)after surgery(P＞0.05).For patients with lower calyceal calculi with infundibulopelvic angle(IPA)＜45°,the SFR of the UAS+FRUS group was significantly lower than that of the SMP group(57.14％vs.100％,P＜0.05).The UAS+FRUS group had a longer operation time than the SMP group[(104.94±8.79)minutes vs.(77.98±6.60)minutes,P＜0.001],higher hospitalization costs[(23 112.82±1152.34)yuan vs.(21 975.84±1512.24)yuan,P＜0.001],less postoperative decrease in hemoglobin[(6.71±2.07)g/L vs.(9.81±4.80)g/L,P＜0.001],and shorter postoperative hospitalization time[(3.28±0.51)d vs.(5.58±0.71)d,P＜0.001].The UAS+FRUS group had lower postoperative VAS score at 6,24,and 48 hours than the SMP group[(6.38±0.69)vs.(7.87±0.88);(3.62±0.73)vs.(5.81±0.83)and(3.12±0.33)vs.(3.81±0.60)],with statistical significance(P＜0.05).Conclusion Both surgical methods have a high SFR in the treatment of renal calculi of 2-3 cm.SMP has the advantages of short operation time,low hospitalization costs,and high SFR for lower calyx calculi,while UAS+FURS has the advantages of little bleeding,minimal trauma,and short hospital stay.Surgeons can make reasonable choices based on the patients'condition and willingness,combined with their own surgical experience.

Objective To clone the full-length sequence,subcellular localization,and analyze the expression patterns of the β-caryophyllene synthase gene(AaCPS)of Artemisia argyi,in order to lay a foundation for the gene function analysis of sesquiterpene biosynthesis pathway in A.argyi.Methods The genes annotated as CPS were selected from the transcriptome data of A.argyi.The full-length cDNA sequence of the target gene was obtained by PCR,and the coding region was analyzed using bioinformatics.A prokaryotic expression vector was constructed and transformed into Escherichia coli competent cells to express recombinant protein.A green fluorescent protein(GFP)fused expression vector was constructed,and the subcellular localization of AaCPS was observed using Agrobacterium tumefaciens transient expression method in tobacco.Real-time quantitative PCR(qRT-PCR)was used to analyze the expression patterns of the AaCPS at different harvest times(April,May,June,July).Determination of β-caryophyllene by HS-SPME-GC-MS and correlation analysis.Results The AaCPS gene was cloned from A.argyi.The full-length open reading frame(ORF)was 1647 bp,encoding 548 amino acids.The molecular weight was 63 667 Da with a theoretical pI of 5.94.AaCPS contained conserved Terpen_synth and Terpen_synth_C domains.Phylogenetic analysis indicated that AaCPS was closely related to the CPS protein of Artemisia annua.SDS-PAGE showed the presence of target protein bands between 75 000-120 000 Da(containing 28 132 Da of the labeled protein),indicating successful expression of the AaCPS protein.The protein was found to be localized in the cytoplasm.As shown by qRT-PCR,the expression of AaCPS gene showed an upward trend,reaching the highest in July.The results of HS-SPME-GC-MS showed that the content of β-caryophyllene increased gradually from April to the highest in June.It is consistent with the trend of AaCPS gene expression from April to June.Conclusion Through the cloning and analysis of AaCPS gene,a foundation has been laid for further study of the functional identification of the AaCPS gene in the sesquiterpenes biosynthesis pathway in A.argyi.

That the property of peripheral pulmonary lesions(PPLs)is clarified need conduct biopsy,while it brings challenge for clinical diagnosis because the PPLs position stays away from the central airway and close to the pleura.Robotic bronchoscopy system is a new technique to help the diagnosis for pulmonary lesions,which can be used in navigation,positioning,biopsy and interventional treatment.Compared with conventional bronchoscopy,it is more stable and accurate,and it can reach farther and thinner inside of the airways.Moreover,the robotic bronchoscopy system can combine with many inspection equipment to further improve the accuracy of biopsy.At the same time,it has fewer complications than conventional percutaneous lung puncture biopsy.This article reviewed the development and application of robotic bronchoscopy,and prospected the combination of that and interventional therapy,which can provide more choices for PPLs biopsy method.

Objective:To study the effect of Long non-coding RNA(LncRNA)small nucleolar RNA host gene 12(SNHG12)regulating miR-138-5p/hypoxia inducible factor-1(HIF-1α)axis on improving the damage of hypoxia/reoxygenation(H/R)human vas-cular endothelial cells.Methods:Human umbilical vein endothelial cells(HUVECs)were cultured in vitro and randomly divided into control group,H/R model group,H/R+LncRNA SNHG12 overexpression group,H/R+miR-138-5p mimics group,H/R+co-transfec-tion group and H/R+co-transfection negative control group,each transfection group was transfected separately,and except for control group,the remaining groups were given hypoxia for 5 hours and then reoxygenated for 1 hour to induce the cell models,and then the cell viability of each group was detected by CCK-8 experiment;the cell apoptosis in each group was detected by flow cytometry experi-ment,and the apoptosis rate of each group was compared;the levels of reactive oxygen species(ROS),lactate dehydrogenase(LDH)and inflammatory factors IL-6,IL-17 and IL-18 in each group were measured by the kit;the expressions of miR-138-5p and HIF-1α mRNA in cells of each group were measured by real-time quantitative PCR(qRT-PCR)experiment;the expressions of apoptotic pro-teins caspase-9,Bcl-2-associated X protein(Bax)and HIF-1α in each group were evaluated by Western blot.Results:Compared with control group,the apoptosis rate,cellular ROS,LDH,IL-6,IL-17 and IL-18 levels,cellular HIF-1α mRNA and protein levels,cellular caspase-9,Bax and HIF-1α protein levels were increased in H/R model group(P<0.05),the cell viability and miR-138-5p level were decreased(P<0.05).Compared with H/R model group and H/R+co-transfection group,the cell viability,cell HIF-1αmRNA and protein levels were increased in H/R+LncRNA SNHG12 overexpression group(P<0.05),the apoptosis rate,cellular ROS,LDH,IL-6,IL-17 and IL-18 levels,cellular caspase-9 and Bax protein levels,and miR-138-5p level were decreased(P<0.05);the cell viability,cellular HIF-1α mRNA and protein levels were decreased in H/R+miR-138-5p mimics group(P<0.05),the apoptosis rate,cellular ROS,LDH,IL-6,IL-17 and IL-18 levels,cellular caspase-9 and Bax protein levels were increased(P<0.05).Com-pared with H/R model group,there was no significant difference in cell index levels between the H/R+co-transfection negative control group and the H/R+co-transfection group(P>0.05).Conclusion:LncRNA SNHG12 can upregulate HIF-1α expression by downregulat-ing miR-138-5p expression,inhibit H/R-induced inflammation and oxidative stress in HUVECs,and reduce cell damage and apoptosis.

Objective:To investigate the clinical significance of the transforming growth factor-β receptor I (TGF-βRⅠ) expression in na?ve CD4 + T cells from patients with systemic lupus erythematosus (SLE). Methods:Na?ve CD4 + T cells were purified using magnetic microbeads from peripheral blood mononuclear cells of SLE patients and healthy controls. Real-time quantitative PCR was used to detect TGF-βRⅠ mRNA level, and flow cytometry was used to detect the percentage of CD69 +CD4 + T cells. Data were analyzed by t test and Pearson correlation analysis. Results:The level of TGF-βR Ⅰ mRNA in na?ve CD4 + T cells from SLE patients was significantly lower than that in healthy controls [(0.674±0.873) vs (1.445±1.112), t=2.301, P<0.05]. The TGF-βR Ⅰ mRNA level was negatively correlated with systemic lupus erythematosus disease activity index (SLEDAI) ( r=-0.376, P<0.05), erythrocyte sedimentation rate (ESR) ( r=-0.376, P<0.05), serum creatinine ( r=-0.323, P<0.05) and 24 h urine protein ( r=-0.331, P<0.05), and positively correlated with serum com-plement C3 ( r=0.528, P<0.01). The level of TGF-βRⅠ mRNA level in na?ve CD4 + T cells in SLE patients with renal involvement was lower than that in SLE patients without renal involvement [(0.525±0.536) vs (1.071±1.007), t=2.198, P<0.05]. The TGF-βR Ⅰ mRNA level in the na?ve CD4 + T cells in anti-dsDNA antibody positive group was lower than that in the anti-dsDNA antibody negative group [(0.344±0.315) vs (0.958±1.076), t=2.277, P<0.05]. The expression of TGF-βRⅠ mRNA in na?ve CD4 + T cells from SLE patients was reduced after 24 h stimulation with anti-CD3/CD28 beads [(0.047±0.013) vs (1.008±0.129), t=14.38, P<0.01], which was partially reversed by dexamethasone treatment [(0.240±0.042) vs (0.047±0.013), t=7.845, P<0.01]. Meanwhile, dexamethasone significantly decreased the expression of CD69 in CD4 + T cells [(15.0±2.1)% vs(34.9±2.0)%, t=32.57, P<0.01]. Conclusion:The abnormally low expression of TGF-βRⅠ in na?ve CD4 + T cells may be involved in the pathogenesis of SLE. Glucocorticoid treatment can upregulate the expression of TGF-βRI and inhibit the activation of T cells, This suggests suggesting that TGF-βRⅠ may be a potential target for SLE treatment.

Objective To explore the efficacy of moderate dose bromocriptine by one-off oral administration in treatment of patients with non-acute prolactin (PRL) type pituitary adenoma.Methods Forty-three patients with definite diagnosis of non-acute prolactin type pituitary adenoma,admitted to our hospital from January 2016 to December 2017,were chosen in our study.All patients were administrated with 5 mg bromocriptine at 18 pm;the serum PRL levels were examined at 2,3 and 12 h after bromocriptine administration.The curative effects of these patients were judged by decline rate of PRL,and the curative effects of patients with different genders,different initial PRL levels and different ages were compared.Results In these 43 patients,bromocriptine showed excellent effect in 20 patients,obvious effect in 18 and invalid effect in 5.There were statistically significant differences in the efficacy of bromocriptine between different genders (P＜0.05).There were statistically significant differences in efficacy of patients with different genders after taking bromocriptine (P＜0.05).The female patients had obviously higher rate of obvious effect than the male patients.Patients with different initial PRL values had statistically significant differences in efficacy after taking bromocriptine (P＜0.05).Patients with PRL initial value of 40-200 ng/mL had significantly higher rate of obvious effect than patients with PRL initial value of ＞200 ng/mL.There was no significant difference in efficacy between patients ＜ 45 years old and patients＞45 years old (P＞0.05).Conclusion The treatment ofhyperprolactin caused by prolactin type pituitary adenoma with moderate dose bromocriptine by one-off oral administration is effective;female patients have obviously better effect than male patients;and for patients with initial prolactin＞200 ng/mL,the effect is better.
