[Objective] To compare the clinical efficacy of super pulse thulium laser enucleation of the prostate (SPThuLEP) with "open tunnel" and transurethral holmium laser enucleation of the prostate (HoLEP) in the treatment of benign prostatic hyperplasia (BPH), in order to provide reference for the treatment options of BPH. [Methods] The clinical data of 112 BPH patients treated in our hospital during Jan.2023 and Jul.2023 were retrospectively analyzed, including 65 treated with SPThuLEP with "open tunnel" and 57 with HoLEP.The operation time, postoperative hemoglobin decrease, postoperative bladder irrigation, catheter indwelling time, hospitalization time and complications were compared between the two groups.The changes of maximum urine flow rate (Qmax), international prostate symptom score (IPSS), quality of life score (QoL), postvoid residual (PVR) and prostate-specific antigen (PSA) were compared between the two groups before operation and one month after operation. [Results] All operations were successful without conversion to open or transurethral plasmakinetic resection.The postoperative decrease of hemoglobin in SPThuLEP group was lower than that in HoLEP group [(13.12±6.72) g/L vs. (21.02±6.51) g/L], with statistical difference (P<0.05). There were no significant differences in the operation time [(63.35±15.73) min vs.(61.02±17.55) min], postoperative bladder irrigation time [(1.07±0.45) d vs. (1.06±0.36) d], catheter indwelling time [(2.98±0.56) d vs. (3.01±0.63) d] and hospitalization time [(3.63±0.61) d vs.(3.79±0.76) d] between the two groups (P>0.05). No blood transfusion, secondary bleeding or unplanned hospitalization occurred, and there were no serious complications such as transurethral electroresection syndrome (TURS), urethral stricture and urinary incontinence.One month after operation, the Qmax, IPSS, QoL, PVR and PSA of the two groups were significantly improved compared with those before operation (P<0.05), but with no statistical difference between the two groups (P>0.05). [Conclusion] SPThuLEP with "open tunnel" has comparable efficacy as HoLEP in the treatment of BPH.With advantages of small amount of bleeding and high safety, this minimally invasive technique can be widely popularized in clinical practice.

Objective To investigatethe relationship between gastroesophageal reflux disease (GERD) symptoms and clinicopathological characteristics, p53 expression, and survival of Chinese patients with esophageal adenocarcinoma. Methods A total of 3882 patients with esophageal adenocarcinoma, 970 matched patients with esophageal squamous cell carcinoma, and 970 matched patients with gastric cardia adenocarcinoma were included to compare the incidence of GERD symptoms. Patients with esophageal adenocarcinoma were divided into two groups according to the presence and absence of GERD symptoms. The differences in clinicopathological characteristics and p53 expression between the two groups were compared by chi-square test, and the differences in survival between the two groups were compared by landmark analysis. Results The incidence of GERD symptoms increased successively in esophageal squamous cell carcinoma, esophageal adenocarcinoma, and gastric cardia adenocarcinoma. In patients with esophageal adenocarcinoma, the proportions of male, less than 65 years old, lower thoracic tumors, tumors without squamous cell carcinoma, poorly differentiation, early tumors (stage 0-I), and p53-positive tumors in the group with GERD symptoms were higher than those in the group without GERD symptoms; moreover, the long-term survival (≥15 years) was better. Conclusion GERD symptom is an important clinical sign of esophageal adenocarcinoma. It is closely related to specific clinicopathological characteristics, p53 overexpression, and good long-term prognosis.

T-cell acute lymphoblastic leukemia (T-ALL) is a highly aggressive hematologic malignancy with a poor prognosis, despite advancements in treatment. Many patients struggle with relapse or refractory disease. Investigating the role of the super-enhancer (SE) regulated gene ubiquitin-specific protease 20 (USP20) in T-ALL could enhance targeted therapies and improve clinical outcomes. Analysis of histone H3 lysine 27 acetylation (H3K27ac) chromatin immunoprecipitation sequencing (ChIP-seq) data from six T-ALL cell lines and seven pediatric samples identified USP20 as an SE-regulated driver gene. Utilizing the Cancer Cell Line Encyclopedia (CCLE) and BloodSpot databases, it was found that USP20 is specifically highly expressed in T-ALL. Knocking down USP20 with short hairpin RNA (shRNA) increased apoptosis and inhibited proliferation in T-ALL cells. In vivo studies showed that USP20 knockdown reduced tumor growth and improved survival. The USP20 inhibitor GSK2643943A demonstrated similar anti-tumor effects. Mass spectrometry, RNA-Seq, and immunoprecipitation revealed that USP20 interacted with hypoxia-inducible factor 1 subunit alpha (HIF1A) and stabilized it by deubiquitination. Cleavage under targets and tagmentation (CUT&Tag) results indicated that USP20 co-localized with HIF1A, jointly modulating target genes in T-ALL. This study identifies USP20 as a therapeutic target in T-ALL and suggests GSK2643943A as a potential treatment strategy.

Objectives:This study aims to explore the clinical significance of lateral pelvic sentinel lymph node biopsy (SLNB) using indocyanine green (ICG) fluorescence navigation in laparoscopic lateral pelvic lymph node dissection (LLND) and evaluate the accuracy and feasibility of this technique to predict the status of lateral pelvic lymph nodes (LPLNs).Methods:The clinical and pathological characteristics, surgical outcomes, lymph node findings and perioperative complications of 16 rectal cancer patients who underwent SLNB using ICG fluorescence navigation in laparoscopic LLND in the Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College during April 2017 and October 2022 were retrospectively collected and analyzed. The patients did not receive preoperative neoadjuvant radiotherapy and presented with LPLNs but without LPLN enlargement (MRI showed the maximum short axes of the LPLNs were ≥5 mm and <10 mm at first visit).Results:All 16 patients were successfully performed SLNB using ICG fluorescence navigation in laparoscopic LLND. Three patients underwent bilateral LLND and 13 patients underwent unilateral LLND. The lateral pelvic sentinel lymph nodes (SLNs) were clearly fluorescent before dissection in 14 patients and the detection rate of SLNs for these patients was 87.5%. Lateral pelvic SLN metastasis was diagnosed in 2 patients and negative results were found in 12 patients by frozen pathological examinations. Among the 14 patients in whom lateral pelvic SLNs were detected, the dissected lateral pelvic non-SLNs were all negative. All dissected LPLNs were negative in two patients without fluorescent lateral pelvic SLNs. The specificity, sensitivity, negative predictive value, and accuracy was 85.7%, 100%, 100%, and 100%, respectively.Conclusions:This study indicates that lateral pelvic SLNB using ICG fluorescence navigation shows promise as a safe and feasible procedure with good accuracy. This technique may replace preventive LLND for locally advanced lower rectal cancer.

Objective:To investigate the differences of protein expressions in the primary tumors, adjacent tissues, and metastatic tumors of gastrointestinal neuroendocrine neoplasms.Methods:Nine patients with gastrointestinal neuroendocrine tumors (GI-NENs) with liver metastasis who underwent surgery at the National Cancer Center/Cancer Hospital, Chinese Academy of Medical Sciences from July 2015 to April 2019 were selected. The protein expressions of the primary tissues, liver metastatic tissues, and adjacent tissues were detected by the data independent acquisition (DIA) technology. P<0.05 and | log 2FC|>0.5 (FC as the difference multiple) were used as the criteria to identify the differentially expressed proteins in the primary tissues vs adjacent tissues, primary tissues vs liver metastatic tissues, primary tissues with different degrees of differentiation, and liver metastatic tissues with different degrees of differentiation. The differentially expressed proteins were investigated by volcano map analysis, cluster analysis, Gene Ontology (GO) function analysis, and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis. Results:Compared with adjacent tissues, 85 proteins were downregulated and 42 proteins were upregulated in the primary tissues of gastric NENs. The differentially expressed proteins were mainly enriched in the biological processes related to the regulation of guanosidase triphosphate activity and the catabolism of deoxyribonucleoside monophosphate, the glycosaminoglycan biosynthesis chondroitin sulfate/dermatan sulfate, pantothenate, and CoA biosynthesis signaling pathways. 114 proteins were downregulated and 155 proteins were upregulated in the primary tissues of intestinal NENs. The differentially expressed proteins were mainly enriched in the biological processes related to glutathione metabolism and sulfur compound metabolism, collecting duct acid secretion, and taurine and hytaurine metabolism signaling pathways. Compared with the primary tissues of neuroendocrine cancers (NECs), 168 proteins were downregulated and 278 proteins were upregulated in G1-2 differentiation primary tissues. The differentially expressed proteins were significantly enriched in biological processes such as DNA metabolism and DNA replication, as well as replication, mismatch repair, and other pathways. Compared with the metastatic tissues of NECs, 95 proteins were downregulated and 97 proteins were upregulated in G1-2 differentiated metastases. The differentially expressed proteins were significantly enriched in the activity and catalytic activity of transcriptional coactivators, base excision repair, and protein efflux pathways. Compared with G1 differentiated primary tissues, 530 proteins were downregulated and 211 proteins were upregulated in G1 differentiated metastatic tissues. Compared with G2 differentiated primary lesions, 53 proteins were downregulated and 96 proteins were upregulated in G2 differentiated metastatic tissues. Compared with the primary lesions of NECs, 109 proteins were downregulated and 92 proteins were upregulated in the metastatic tissues of NECs. In G1 and G2 differentiated GI-NENs, there are many similar signal pathways enriched in differentially expressed proteins between primary lesions and metastases, while only one signal pathway enriched in differentially expressed proteins between primary and metastatic tissues of NECs is the same as that enriched in differentially expressed proteins between primary and metastatic tissues of GI-NENs, which is the drug metabolism signal pathway. The differentially expressed proteins in G1 differentiated primary and metastatic tissues were mainly expressed in cytoplasm (20.26%), mitochondria (18.67%), and nucleus (15.48%). The differentially expressed proteins in the primary and metastatic tissues of G2 differentiation were mainly expressed in the cytoplasm (20.24%), nucleus (18.25%), and cell membrane (15.08%). The differentially expressed proteins in the primary and metastatic tissues of NECs were mainly expressed in the nucleus (23.78%), cytoplasm (22.7%), and cell membrane (11.35%).Conclusion:The protein expressions of GI-NENs in the primary tissues, adjacent tissues, and metastatic tissues were significantly different in different sites and degrees of differentiation.

OBJECTIVE To establish a UPLC-HRMS method for simultaneous determination of 43 chemical drugs in blood and apply the method to determine the content of 43 chemical drugs in blood of 100 abnormal death from Hangzhou. METHODS Proteins were precipitated using acetonitrile. After centrifugation, the supernatant was collected and dried under a nitrogen stream. The residue was reconstituted with the initial mobile phase, centrifuged, and the supernatant was filtered through a 0.22 μm microporous membrane for instrument analysis. Separation was performed using a C18(150 mm×2.1 mm, 3.0 μm) chromatographic column. The mobile phase consisted of 0.1% formic acid+5 mmol ammonium formate(phase A) and methanol+0.1% formic acid(phase B) with gradient elution. Mass spectrometric detection was carried out using an electrospray ionization source(HESI-II) with simultaneous positive and negative ion scanning and real-time tandem mass spectrometry scanning(Full MS/ddMS2). RESULTS The linearity of 43 chemical drugs within the range of 10 to 1000 ng·mL−1 was good, with r2 ranging from 0.9910 to 0.9998; the limit of quantification was 10 ng·mL−1; the matrix effect was between 79.4% and 99.7%; the method recovery rate was between 80.4% and 97.0%; the intra-day precision(RSD) ranged from 0.1% to 3.2%; and the inter-day precision(RSD) ranged from 0.6% to 9.8%. Using this method, 100 whole blood samples from the Hangzhou Public Security Judicial Identification Center were tested, with 2 samples detected, both of which contained sibutramine. CONCLUSION The method is sensitive and accurate for fast detection of 43 chemical drugs in human blood.

ObjectiveTo explore the effect of core muscles training based on spinal fine-tuning manipulation on lumbar facet joint disorders. MethodsFrom February, 2021 to February, 2022, 80 patients with lumbar facet joint disorders in Huadong Hospital Affiliated to Fudan University were randomly divided into control group (n = 40) and observation group (n = 40) randomly. Both groups received routine treatment and spinal fine-tuning manipulation, while the observation group received core muscles training in addition, for six weeks. They were assessed with Japanese Orthopaedic Association (JOA) scores, Short-Form of McGill Pain Questionnaire and World Health Organization Quality of Life-BREF before and after treatment. The recurrence rate was observed after three months follow-up. ResultsThe scores of all the scales improved after treatment (t > 5.751, P < 0.001), and improved more in the observation group than in the control group (t > 2.051, P < 0.05). After three months follow-up, the recurrence rate was 7.89% (3/38) in the observation group, less than 28.13% (9/32) in the control group (χ² = 5.005, P = 0.025). ConclusionCombination of core muscles training may improve lumbar function, reduce lumbar pain, reduce recurrence and improve quality of life for patients with lumbar facet joint disorders.

Objective: To investigate the association between high normal blood pressure, hypertension and microalbuminuria (MAU), so as to provide the basis for early screening and prevention of renal injury caused by hypertension. Methods: A multi-stage cluster random sampling method was used to select permanent residents aged 18 to 75 years from six provinces including Hebei, Hunan, Sichuan, Heilongjiang, Qinghai and Jiangxi from September to October 2021. Basic information and lifestyle behaviors were collected through questionnaires. Indices including height, weight and blood pressure were measured. Urinary microalbumin and creatinine were measured in 24-hour urine samples. The associations between high normal blood pressure, hypertension, and MAU were analyzed by using a multivariable logistic regression model. Results: A total of 1 982 residents were surveyed, with 996 residents aged <50 years (50.25%) and 986 residents aged ≥50 years (49.75%). There were 958 males (48.34%) and 1 024 females (51.66%). Normal blood pressure was observed in 653 residents (32.95%), high normal blood pressure in 748 (37.74%) and hypertension in 581 (29.31%). MAU was detected in 164 participants, with a detection rate of 8.27%. The detection rates of MAU among residents with normal blood pressure, high normal blood pressure, and hypertension were 2.14%, 8.16% and 15.32%, respectively, and the difference was statistically significant (P<0.05). Multivariable logistic regression analysis showed that after adjusting for gender, age, educational level, smoking, alcohol consumption, regular exercise and body mass index, the residents with high normal blood pressure (OR=3.535, 95%CI: 1.898-6.585) and hypertension (OR=7.232, 95%CI: 3.808-13.732) had higher risks of MAU compared to those with normal blood pressure; the residents with hypertension (OR=1.914, 95%CI: 1.340-2.735) had a higher risk of MAU compared to those with high normal blood pressure. Conclusions High normal blood pressure and hypertension are associated with an increased risk of MAU.
