OBJECTIVES:
To analyze the association of CHMP2B expression level of with clinicopathological characteristics and prognosis of clear cell renal cell carcinoma (CRCC) and the possible role of CHMP2B in tumorigenesis and progression of CRCC.
METHODS:
RNAseq data of CRCC were downloaded from the TCGA database for analysis of CHMP2B expression levels in tumor and adjacent tissues and their correlation with clinicopathological characteristics of the patients. Survival outcomes of the patients with high and low CHMP2B expressions were analyzed using the Kaplan-Meier model, and the COX risk regression model was used for identifying the prognostic factors of the patients. The correlation between CHMP2B expression and immune infiltration, its co-expressed genes, and the effect of CHMP2B gene mutations on immunotherapy responses, and its immunohistochemical expression in CRCC and normal tissues were analyzed. Clinical samples of CRCC were collected to examine CHMP2B expressions using RT-PCR, and cell experiment was carried out to test the effect of CHMP2B overexpression on biological behaviors of CRCC cells.
RESULTS:
CHMP2B was significantly under-expressed in renal cancer tissues, and its overexpression obviously inhibited the proliferation of CRCC cells in vitro. CHMP2B expression level was significantly correlated with age, gender, lymph node metastasis, and tumor stage, and the patients with low CHMP2B expression had poor survival outcomes. Enrichment and co-expression gene analyses suggested that CHMP2B was mainly involved in viral outgrowth, necrotic apoptosis, endocytosis, and immune-regulatory processes in kidney cancer.
CONCLUSIONS
CHMP2B is lowly expressed in renal cancer tissues to affect tumor progression and tumor immune processes, and may serve as a prognostic biomarker and therapeutic target for CRCC.

ObjectiveTo observe the clinical efficacy and safety of traditional Chinese medicine (TCM) triple therapy in the treatment of spontaneous bacterial peritonitis (SBP) with damp-heat stagnation and toxin-blood stasis syndrome in liver cirrhosis patients, and to explore its potential mechanisms of action. MethodsEighty-six patients were randomly divided into the experimental group and the control group, with 43 patients in each group. Both groups received standard western medicine treatment, while the experimental group additionally received TCM triple therapy, including oral Qingre Liangxue Jiedu Decoction (清热凉血解毒汤), retention enema with Dachengi Decoction (大承气汤), and abdominal application of Qingre Zhitong Lishui Fomulation (清热止痛利水方) with lotus leaf. Both groups were treated for 2 weeks. Before and after treatment, various indicators were measured, such as TCM syndrome scores, ascites volume measured by abdominal ultrasound, liver function indicators including total bilirubin (TBIL), alanine aminotransferase (ALT), aspartate aminotransferase (AST), and albumin (ALB), infection markers, including neutrophil percentage (NEUT%), C-reactive protein (CRP), and procalcitonin (PCT), inflammatory factors, such as tumor necrosis factor-alpha (TNF-ɑ), interleukin-6 (IL-6), and interleukin-10 (IL-10), intestinal mucosal barrier function markers, including endotoxin (ET), diamine oxidase (DAO), D-lactic acid (D-Lac), occludin, and zonula occludens-1 (ZO-1), and peritoneal polymorphonuclear (PMN) cell counts at 72 hours post-treatment. ResultsA total of 82 patients were included in the final analysis, with 41 patients in each group. The total effective rate for TCM syndrome in the experimental group was 92.68% (38/41), which was significantly higher than the 80.49% (33/41) in the control group (P<0.05). Compared with pre-treatment values, both groups showed significant reductions in TCM syndrome scores, ascites volume, TBIL, ALT, AST, NEUT%, CRP, PCT, TNF-α, IL-6, ET, DAO, D-Lac, Occludin, and ZO-1, with an increase in IL-10 levels and a decrease in PMN count in ascites 72 hours post-treatment (P<0.05). Furthermore, the experimental group outperformed the control group in all the above indicators after treatment (P<0.05). The disappearance time of fever and abdominal pain was shorter in the experimental group than in the control group (P<0.01). There were no significant changes in routine urine and stool tests, renal function, electrolytes, or electrocardiogram in either group compared with pre-treatment values. ConclusionTCM triple therapy in addition to western medicine routine treatment could significantly improves clinical symptoms in patients with liver cirrhosis and SBP with damp-heat stagnation and toxin-blood stasis syndrome, alleviates liver inflammation, improves liver function, accelerates the resolution of ascites, and increases clinical efficacy. The potential mechanism may be related to the regulation of the inflammatory response and the promotion of intestinal mucosal barrier repair.

BACKGROUND:
P16 inactivation is frequently accompanied by telomerase reverse transcriptase ( TERT ) amplification in human cancer genomes. P16 inactivation by DNA methylation often occurs automatically during immortalization of normal cells by TERT . However, direct evidence remains to be obtained to support the causal effect of epigenetic changes, such as P16 methylation, on cancer development. This study aimed to provide experimental evidence that P16 methylation directly drives cancer development.
METHODS:
A zinc finger protein-based P16 -specific DNA methyltransferase (P16-Dnmt) vector containing a "Tet-On" switch was used to induce extensive methylation of P16 CpG islands in normal human fibroblast CCD-18Co cells. Battery assays were used to evaluate cell immortalization and transformation throughout their lifespan. Cell subcloning and DNA barcoding were used to track the diversity of cell evolution.
RESULTS:
Leaking P16-Dnmt expression (without doxycycline-induction) could specifically inactivate P16 expression by DNA methylation. P16 methylation only promoted proliferation and prolonged lifespan but did not induce immortalization of CCD-18Co cells. Notably, cell immortalization, loss of contact inhibition, and anchorage-independent growth were always prevalent in P16-Dnmt&TERT cells, indicating cell transformation. In contrast, almost all TERT cells died in the replicative crisis. Only a few TERT cells recovered from the crisis, in which spontaneous P16 inactivation by DNA methylation occurred. Furthermore, the subclone formation capacity of P16-Dnmt&TERT cells was two-fold that of TERT cells. DNA barcoding analysis showed that the diversity of the P16-Dnmt&TERT cell population was much greater than that of the TERT cell population.
CONCLUSION
P16 methylation drives TERT -mediated immortalization and transformation of normal human cells that may contribute to cancer development.

Objective To analyze the difference of diseases between the coal mine workers and the general population inpatients by the disease spectrum in Datong City. Methods A total of 282 639 hospitalized patients in Datong City in 2023 were included as the study subjects. Participants were divided into a general population group and a coal mine workers group based on health insurance types, with 247 897 and 34 742 cases, respectively. The disease spectrum of participants in both groups was coded and analyzed according to the International Statistical Classification of Diseases and Related Health Problems, 10th Revision (ICD-10). The standardized constituent ratios of disease categories were calculated and compared between the two groups. Results Patients aged 60-<70 years had the largest standardized proportion in both cohorts (29.02% in the general population group and 33.08% in coal mine workers group). Circulatory system diseases had the highest standardized proportion in both groups. Within the top six disease categories ranked by standardized composition ratio in the coal mine workers, three demonstrated a higher burden, including neoplasms (C00-D48), symptoms, signs and abnormal clinical/laboratory findings not elsewhere classified (R00-R99), and factors influencing health status/contact with health services (Z00-Z99), compared with the general population (11.82% vs 10.44%, 12.99% vs 8.03%, and 6.17% vs 2.04%, respectively). In both groups, male workers had higher standardized constituent ratios of circulatory, respiratory, and digestive system diseases than females (coal mine workers group, 19.53% vs 14.31%, 13.56% vs 9.10%, 10.61% vs 8.43%; general population group, 26.15% vs 22.42%, 15.45% vs 11.87%, 11.52% vs 10.41%). Conversely, the ratios for conditions classified under symptoms, signs and abnormal clinical/laboratory findings not elsewhere classified (R00-R99). and factors influencing health status/contact with health services (Z00-Z99) were higher in females than males (coal mine workers group, 13.31% vs 12.68%, 7.26% vs 5.13%; general population group, 8.91% vs 7.18%, 2.35% vs 1.74%). Mental and behavioral disorders (F00-F99) were most prevalent in the 22-<50-year age group in the general population (9.92%) and in the 50-<60-year age group in coal mine workers (8.58%). The standardized proportion of respiratory system diseases ranked first in≥80-year age workers in general population group and coal mine workers group (29.54% and 26.46%, respectively). Regarding specific malignancies, unspecified malignant neoplasm of the bronchus or lung was the most common cancer among males in both groups (3.44% and 3.62%). Among females, the standardized proportion of unspecified malignant neoplasm of breast was higher in coal mine workers group than in the general population group (2.60% vs 2.09%). Conclusion Neoplasms, abnormal symptoms, and mental health disorders should be prioritized in disease prevention strategies for coal mine workers. Greater attention should be paid to mental health screening in younger populations, and medical resource allocation should be optimized according to sex-specific high-incidence cancers.

Objective:To investigate a surgical method and clinical outcomes of a fascia pedicled island flap with dorsal branch of proper palmar digital nerve in reconstruction of defects of digital pulp.Methods:Seventy-five patients who had digital pulp defects and treated at Department of Orthopaedics, Xinjiang Production and Construction Corps Alar Hospital, Shaw Hospital Affiliated Zhejiang University School of Medicine, from December 2019 to December 2022, were retrospectively analysed. The patients were 40 males and 35 females aged 25-61 years with an average age of 42 years. The defects of digital pulp involved in 23 thumbs, 15 per group of index fingers, middle fingers and ring fingers, and 7 little fingers. The digital pulp defects were 0.8 cm×0.9 cm to 1.5 cm×2.1 cm in size, and the sizes of flap were 1.0 cm×1.2 cm to 1.8 cm×2.4 cm. Donor sites were covered by medium-thickness skin grafts and pressurised bandage was applied. Clinical outcomes of the surgery were monitored through the postoperative follow-ups at outpatient clinic, WeChat and telephone reviews.Results:Postoperative follow-up ranged 9 to 15 months, with an average of 12 months. The donor sites and skin grafts all achieved stage-I healing. Seventy-three flaps completely survived after surgery. However, 2 flaps had partial necrosis, which healed after dressing changes, 4 flaps encountered flap bruising and swelling, which were rectified by removal of high-tension sutures, and 7 flaps had tension blisters, which had disappeared in 2 weeks. At the final follow-up, the appearance and texture of the flaps were graded as excellent for 54 flaps and good for 21 flaps, all without pale, cyanotic or dark in colour. Forty-nine flaps showed normal elasticity or with slight atrophy, 24 with mild atrophy, 2 with moderate atrophy and none with obvious or severe atrophy. Mobility of the affected digits was rated as excellent for 57 digits (average 42.3°), good for 12 (average 26.7°) and fair in 6 digits (average 16.3°). TPD of flap surfaces ranged 6 to 11 mm, with an average of 8.1 mm. Digital function were evaluated according to the Evaluation Trial Standards of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association, with 48 digits in excellent (average 11.2 points), 22 in good (average 8.1 points) and 5 in fair (average 5.4 points) and with a combined excellence and good rates of 93.33%. All flap donor sites were in normal function. For patient satisfaction: 53 patients were well satisfied, 21 were fairly satisfied and 1 was dissatisfied.Conclusion:Application of the island flap with dorsal branch of proper palmar digital nerve with fascio-pedicled in reconstruction of the defect of digital pulp has a high survival rate, simple surgical operation, good satisfactory outcome, with the digital artery being remained intact.
