Objective To evaluate the efficacy and safety of modified pelvic floor reconstruction in non-nerve-sparing robot-assisted radical prostatectomy (NNS RARP) for improving postoperative urinary control. Methods A retrospective analysis was conducted on the clinical data of 79 prostate cancer patients who underwent NNS RARP at Tangdu Hospital during Jan.2020 and Dec.2023, including 29 in the reconstruction group, and 50 in the non-reconstruction group. The baseline characteristics including age, body mass index, prostate-specific antigen (PSA) level, clinical stage, prostate volume, and biopsy Gleason score, and perioperative indexes including operation time, intraoperative blood loss, catheter indwelling time, complication rate, and positive rate of surgical margins were compared between the two groups. Additionally, urinary continence function was assessed before operation and 1,3,6, and 12 months after operation using the international consultation on incontinence questionnaire-short form (ICIQ-SF) and the incontinence quality of life questionnaire score (I-QoL). Results No statistically significant differences were observed in the baseline characteristics between the two groups (P>0.05). The operation time was significantly longer in the reconstruction group than in the non-reconstruction group [ (110.24±15.08) min vs. (101.80±9.89) min, P=0.010]. There were no significant differences in intraoperative blood loss, catheter indwelling time, complication rate, and positive rate of surgical margins between the two groups (P>0.05). The reconstruction group demonstrated significantly lower ICIQ-SF scores at 1 month [ (10.17±2.16) vs. (11.56±1.66), P=0.002],3 months [ (7.62±1.29) vs. (9.52±1.80), P<0.001], and 6 months postoperatively [ (4.93±1.22) vs. (6.18± 1.67), P=0.001]compared to the non-reconstruction group (adjusted P<0.0125). Conversely, the I-QoL scores were significantly higher in the reconstruction group at 1 month [ (73.32±10.30) vs. (63.88±9.55), P<0.001]and 3 months postoperatively [ (78.91±4.82) vs. (75.66±5.17), P=0.007] (adjusted P<0.0125). However, no significant differences were found in ICIQ-SF or I-QoL scores between the two groups preoperatively and 12 months postoperatively (adjusted P>0.0125). Conclusion The application of modified pelvic floor reconstruction technique in NNS RARP is safe and feasible. Although it slightly prolongs the operation time, it does not increase surgical risks; instead, it effectively promotes early recovery of postoperative urinary continence, thereby significantly enhancing patients'quality of life.

Objective To investigate the expression and clinical significance of heat shock protein family A member 5(HSPA5)and apolipoprotein B mRNA editing enzyme catalytic polypeptide-like protein 3B(APO-BEC3B)in high-risk human papillomavirus(HR-HPV)positive cervical cancer patients.Methods A total of 86 patients with HR-HPV positive cervical cancer tissues diagnosed and treated in Zhuhai Integrated Tradi-tional Chinese and Western Medicine Hospital from March 2019 to March 2021 were retrospectively collected as the case group,50 cases of HR-HPV negative cervical cancer patients tissues diagnosed and treated during the same period were selected as the case control group,and 50 cases of normal cervical tissues from patients undergoing total hysterectomy were selected as the benign control group during the same period.The protein expressions of HSPA5 and APOBEC3B were analyzed by immunohistochemistry.The expressions of HSPA5 mRNA and APOBEC3B mRNA were detected by real-time fluorescence quantitative PCR.Kaplan-Meier sur-vival curve was used for survival analysis,and Cox proportional hazards regression model was used to analyze the prognostic factors of HR-HPV positive cervical cancer patients.Results The expressions of HSPA5 mR-NA and APOBEC3B mRNA in the case group were higher than that in the case control group and benign con-trol group,and the difference was statistically significant(P＜0.05).The positive expressions of HSPA5 pro-tein and APOBEC3B protein in the case group were higher than those in the case control group and the benign control group,and the difference was statistically significant(P＜0.05).Compared with FIGO stage Ⅰ A-Ⅰ B and without lymph node metastasis,the positive rates of HSPA5 and APOBEC3B proteins in HR-HPV positive cancer tissues with FIGO stage Ⅱ A and lymph node metastasis were higher,and the difference was statistically significant(P＜0.05).The 3-year survival rate of HSPA5 protein positive group was 68.52％(37/54),which was lower than that of HSPA5 protein negative group(87.50％,28/32),and the difference was statistically significant(Log Rank x2=4.103,P=0.043).The 3-year survival rate of APOBEC3B protein positive group was 67.31％(35/52),which was lower than that of APOBEC3B protein negative group(88.24％,30/34),and the difference was statistically significant(Log Rank x2=5.241,P=0.022).FIGO stage(HR=1.570,95％CI:1.038-2.374),lymph node metastasis(HR=1.754,95％CI:1.109-2.775)and HSPA5 protein(HR=1.616,95％CI:1.154-2.265)and APOBEC3B protein(HR=1.449,95％CI:1.095-1.918)in cancer tissues were independent factors affecting the prognosis of HR-HPV positive cervical cancer(P＜0.05).Conclusion HSPA5 and APOBEC3B mRNA and protein levels are significantly increased in HR-HPV positive cervical cancer.The protein expression of HSPA5 and APOBEC3B is related to the pro-gression and prognosis of patients with HR-HPV positive cervical cancer,which is a new prognostic marker for evaluating the prognosis of HR-HPV positive cervical cancer.

Eclipta prostrata L.has been used in traditional medicine and known for its liver-protective properties for centuries.Wedelolactone(WEL)and demethylwedelolactone(DWEL)are the major coumarins found in E.prostrata L.However,the comprehensive characterization of these two compounds on non-alcoholic fatty liver disease(NAFLD)still remains to be explored.Utilizing a well-established zebrafish model of thioacetamide(TAA)-induced liver injury,the present study sought to investigate the impacts and mechanisms of WEL and DWEL on NAFLD through integrative spatial metabolomics with liver-specific transcriptomics analysis.Our results showed that WEL and DWEL significantly improved liver function and reduced the accumulation of fat in the liver.The biodistributions and metabolism of these two compounds in whole-body zebrafish were successfully mapped,and the discriminatory endogenous metabolites reversely regulated by WEL and DWEL treatments were also characterized.Based on spatial metabolomics and transcriptomics,we identified that steroid biosynthesis and fatty acid metabolism are mainly involved in the hepatoprotective effects of WEL instead of DWEL.Our study unveils the distinct mechanism of WEL and DWEL in ameliorating NAFLD,and presents a"multi-omics"platform of spatial metabolomics and liver-specific transcriptomics to develop highly effective compounds for further improved therapy.

Objective:To establish an immortalized human keloid fibroblasts(KFbs) cell line and identify its characteristics and functions.Methods:The specimen was obtained from a 32-year-old female patient who underwent surgical resection of an earlobe keloid at Peking University Third Hospital in November 2019. The keloid tissue obtained was removed from the subcutaneous fat and epidermis. It was then separated and cultured using the tissue sticking method to obtain primary KFbs, which were passaged using the trypsin digestion method. After the primary KFbs were infected with an SV40 lentivirus, purified by puromycin, and passaged, a human KFbs cell line was established. Chromosomal karyotype analysis, short tandem repeat (STR) profiling, and gender gene detection were conducted to identify the primary KFbs and the cell line. The CCK-8 method was used to assess the proliferation ability of the cells. Quantitative real-time PCR (qRT-PCR) and Western blotting were used to detect the mRNA and protein expression levels of specific genes (PGK1, ENO1, LDHA, GLUT1, TGF-β1, COL1, COL3, FN). The comparative analysis of relevant data between primary KFbs and the cell line was conducted using t-test, and P<0.05 indicated statistical significance. Results:The morphology of both the primary KFbs and the cell line was typically spindle-shaped. The cell line morphology was basically similar to that of the primary KFbs, which were continuously cultured and passaged for 20 generations. The gender gene(Amelogenin) detection showed both were females. The chromosome karyotyping of the primary KFbs and cell line was satisfactory, maintaining the fundamental characteristics of normal cells without undergoing malignant transformation. The STR identification results showed that no multiple alleles were found in the cell line, indicating a normal cell genotype. Furthermore, the cell line did not match any entries in known cell databases. After 24, 48, and 72 hours of culture, the proliferation ability of the cell line increased by 76.1%, 125.8%, and 60.3% compared to primary KFbs. The proliferation rates of the cell line were significantly faster than those of primary KFbs ( P<0.05). The mRNA and protein expression levels of the aforementioned genes in the cell line showed no significant changes compared to the primary KFbs ( P>0.05). Conclusion:An immortalized human KFbs cell line was successfully established, showing no significant changes in morphology, characterization, and function, while exhibiting a faster proliferation rate compared to that of primary KFbs.
