This review aims to analyze the current applications of open surgery, laparoscopic surgery, and robotic surgery in the treatment of colorectal cancer, particularly in elderly patients.It compares the differences among these three surgical methods in terms of surgical indicators, as well as short-term and long-term outcomes.Studies have shown that laparoscopic surgery has become the standard treatment for colorectal cancer, resulting in fewer postoperative complications and faster recovery times.While robotic surgery offers advantages in surgical precision and maneuverability, it is associated with longer surgical times and higher costs.For elderly patients, laparoscopic surgery has demonstrated fewer surgical complications and shorter hospital stays, with no significant difference in long-term survival rates compared to open surgery.However, there is limited research on the application of robotic surgery in elderly patients.Future studies should involve larger-scale, multi-centre randomized controlled trials to provide higher-level evidence and scientific guidance for the individualized treatment of elderly colorectal cancer patients.

Uveal melanoma (UM) poses a significant lethality, with approximately 50% of those developing metastases surviving less than one year. In the progression of UM, vasculogenic mimicry (VM) induced by hypoxia plays a pivotal role, which also partially explains the resistance of UM to anti-angiogenic therapies. Nevertheless, the crucial molecular mechanisms underlying VM in the progression of UM remain unclear. We identified ubiquitin conjugating enzyme E2 G2 (UBE2G2) as a critical suppressor through transcriptomic sequencing and metastasis correlation screening. In UM, hypoxia-induced VM and metastasis are markedly exacerbated by UBE2G2 knockdown and significantly alleviated by its overexpression. Mechanistically, UBE2G2 directly binds to galectin 3 binding protein (LGALS3BP) and forms a complex with the E3 ubiquitin ligase tripartite motif containing 38 (TRIM38), facilitating ubiquitination-mediated degradation of LGALS3BP at the K104 residue. Furthermore, UBE2G2 inhibits oncogenic phenotypes by inactivating intracellular PI3K/AKT signaling and reprogramming the tumor microenvironment. Therefore, targeting intercellular and intracellular molecular mechanisms of the hypoxia-UBE2G2-LGALS3BP axis may contribute to developing various therapeutic strategies for UM.

OBJECTIVE To evaluate the efficacy and safety of Huoxue Xiaoyi Granule in inhibiting the recurrence of endometrio-sis(EMs)after conservative operation,and to provide evidence for Chinese medicine in inhibiting the recurrence of EMs.METHODS A total of 72 patients with qi-stagnation and blood-stasis after EMs operation were selected as the study objects and randomly divid-ed into the Chinese medicine group and the Western medicine group,36 cases in each group.The Chinese medicine group was treated with Huoxue Xiaoyi Granule,and the Western medicine group was treated with GnRH-α.The postoperative recurrence rate,TCM syn-drome score,carbohydrate antigen 125(CA125),dysmenorrhea score,pelvic pain score,pregnancy rate,serum sex hormones[estra-diol(E2),luteinizing hormone(LH),follicle stimulating hormone(FSH)]and safety indexes of the two groups were observed.RE-SULTS At 9 months and 12 months after surgery,the total TCM syndrome scores of the two groups of patients were significantly re-duced(P<0.05),and the Chinese medicine group was better than the Western medicine group(P<0.05);12 months later,the TCM total clinical curative rate in the Chinese medicine group was better than that in the Western medicine group;after surgery,the serum CA125 levels,dysmenorrhea scores and pelvic pain severity of the two groups of patients were significantly reduced(P<0.05,P<0.01);during treatment,the total incidence of adverse reactions in the Chinese medicine group was lower than that in the Western medicine group(P<0.01);the recurrence rate of the Chinese medicine group was slightly lower than that of the Western medicine group,but there was no statistical difference(P>0.05).CONCLUSION Huoxue Xiaoyi Granule can significantly improve TCM syndromes in patients with qi-stagnation and blood-stasis after EMs surgery.It is safe and has equivalent efficacy to GnRH-α in pre-venting postoperative recurrence of EMs,and worthy of clinical promotion and application.

Objective:To evaluate the classification of petroclival meningiomas(PCM), proposed selection of microsurgical approach and therapeutic outcomes.Methods:Retrospectively analyzed clinical data of 179 cases of PCM from Department of Neurosurgery, Xiangya Hospital, Central South University between January 2011 and November 2020. There were 28 males and 151 females with an age of(49.9±10.2) years(range: 22 to 75 years) and the tumor size of(44.8±10.3)mm(range: 15 to 80 mm). The mean duration of symptom ( M( Q R)) was 18.0(40.6)months(range:1 week to 320 months) and the mean preoperative Karnofsky performance scale(KPS) was 78.6±13.3(range: 40 to 100). The PCM were classified into 5 types according to the difference in the origin of dural attachment, involvement of adjacent structures and growth patterns through preoperative MRI. The surgical approaches were selected based on the proposed classification, and the clinical characteristics, surgical record, and follow-up data of each type were reviewed. Results:The PCM were divided into clivus type(CV, 4 cases), petroclival type(PC, 60 cases), petroclivosphenoidal type(PC-S, 62 cases), sphenopetroclival type with 2 subtypes(S-PC, 50 cases) and central skull base type(CSB, 3 cases). All of 176 cases were obtained microsurgical treatment except CSB type. The gross total resection reached in 124 cases(70.5%) with 112 cases of retrosigmoid approach(RSA), 27 cases of subtemporal transtentorial transpetrosal approach, 13 cases of pretemporal trancavernous anterior transpetrosal approach(PTCA), 12 cases of extended pterional transtentorial approach(EPTA) and presigmoid combined supra-infratentorial approach, respectively. The RSA could be adopted in both of CV type and PC type and most of PC-S type(71.0%). S-PC subtype Ⅰ and subtype Ⅱ were mainly underwent EPTA(40.8%) and PTCA(52.2%), respectively. Seventy-two cases(40.9%) gained new neurological dysfunctions mainly with the cranial nerve paralysis. The postoperative morbidity and complications were recovered or improved with conservative and positive symptomatic and supportive treatment. There was no intraoperative and postoperative death case. One hundred and sixty four cases(93.2%) of operative patients were followed with the duration of 24(48)months(range:3 to 108 months). Tumor recurrence and progress were identified in 14 cases(10.4%) and 14 cases(28.6%), respectively. Compared with postoperative neurological status, 89 patients(54.3%) had improved and 38 patients(23.2%) were still suffering various degrees of neurological dysfunctions during the follow-up. The recent KPS was 84.2±11.4(range: 50 to 100) without statistical difference from preoperative KPS ( t=-1.356, P=0.125). As for each type, there were statistically significant differences in brain stem edema (χ 2=3.482, P=0.038), gross total resection (χ 2=9.127, P=0.001), surgical duration( F=8.954, P=0.013), postoperative length of stay( F=3.652, P=0.025), postoperative complications (χ 2=1.550, P=0.024), postoperative KPS( F=2.856, P=0.042) and tumor recurrence/progress (χ 2=4.824, P=0.013). Conclusion:The precise and comprehensive classification of PCM and specific individual treatment strategy are benefit to evaluate the diverse clinical prognosis, choose optimal surgical approaches, elevate gross total resection, diminish neurological dysfunctions and restraint tumor recurrence, so as to improve the quality of life for patients.

Objective:To investigate the influencing factors for the recurrence of TNM(T3~4N0M0)stage Ⅱ colorectal cancer in patients aged 75 years and over after radical resection.Methods:Clinicopathologic data of 161 colorectal cancer patients aged 75 years and over undergone radical resection in our hospital from January 2012 to August 2017 were retrospectively analyzed.They were followed up for 49 months(range: 2-84 months). Survival analysis was conducted by the Kaplan-Meier method and the survival rate was examined using the Log-rank method.Multivariate analysis was conducted by the proportional hazards regression model.Results:Univariate analysis showed that age≥80 years, preoperative comorbidities involving more than 1 system, weight loss≥10%, preoperative intestinal obstruction or perforation, preoperative CEA elevation, preoperative CA199 elevation, depth of primary tumor invasion T4, dissection of lymph nodes<12, vascular invasion, nerve invasion, deficient mismatch repair(dMMR), risk stratification and adjuvant chemotherapy were related factors for the prognosis in patients with TNM stage Ⅱ colorectal cancer aged 75 years and over after radical resection.Multivariate analysis showed that preoperative comorbidities involving more than 1 system, weight loss≥10%, preoperative intestinal obstruction or perforation, preoperative CEA elevation, depth of primary tumor invasion T4, dissection of lymph nodes<12 and vascular invasion were independent risk factors for poor prognosis, and adjuvant chemotherapy was an independent factor for favorable prognosis.The 5-year-disease-free survival(DFS)rate was 41.6% in all patients.The Kaplan-Meier curves indicated that disease-free survival(DFS)between the low-risk, middle-risk and high-risk groups had a statistically significant difference( χ2=14.632, P=0.001). Kaplan-Meier survival analysis showed that high-risk patients receiving Oxaliplatin combined with Capecitabine adjuvant chemotherapy had better DFS than those receiving Capecitabine or non-adjuvant chemotherapy( χ2=11.157, P=0.004). Conclusions:DFS is improved in strictly selected patients with stage Ⅱ colorectal cancer aged 75 years and over and at high risk who receive Oxaliplatin combined with Capecitabine adjuvant chemotherapy.

Objective:To investigate the effect of a tankyrase inhibitor NVP-TNKS656 on the growth of hepatocellular carcinoma(HCC)cell lines and the involved molecular mechanisms.Methods:Five HCC cell lines were treated with 0, 2.5, 5.0, 10.0 μmol/L of NVP-TNKS656.The cell lines of HLE and HLF were selected and divided into four groups: 0.0 μmol/L(control or DMSO), 2.5 μmol/L, 5.0 μmol/L, 10.0 μmol/L of NVP-TNKS656 groups.Cells were cultured for 48 h for subsequent experiments.Crystal violet staining was used to count the number of the newly formed cell clones.Western blotting was used to detect the protein expression levels of Yes-associated protein(YAP), angiomotin-like 1(AMOTL1)and AMOTL2.The real-time qRT-PCR was used to detect the mRNA expression of YAP and its downstream connective tissue growth factor(CTGF)and cysteine-rich 61(Cyr61). Dual luciferase reporter gene was used to detect the luciferase activity of transcriptional enhancer activator domain(TEAD)family.Results:NVP-TNKS656 inhibited the growth of 5 HCC cell lines in a dose-dependent manner in HLE, HLF, Huh7, MHCC97-H, and MHCC97-L cell lines.There were significant differences in the newly formed cell clone numbers between control(0 μM of NVP-TNKS656)and each of 2.5 μmol/L, 5.0 μmol/L, 10.0 μmol/L of NVP-TNKS656 groups in a dose-dependent manner( F=90.46, 68.58, 191.8, 114.6 and 201.4, all P<0.05). In HLE and HLF cell lines, NVP-TNKS656 significantly reduced the protein level of YAP in a dose-dependent manner and decreased the YAP target gene CTGF(HLE cells: 1.02±0.02, 0.90±0.03, 0.57±0.02, 0.38±0.03, HLF cells: 0.98±0.03, 0.86±0.02, 0.66±0.02, 0.43±0.01)and Cyr61(HLE cells: 1.00±0.01, 0.86±0.02, 0.74±0.03, 0.44±0.03 and HLF cells: 0.99± 0.02, 0.87±0.01, 0.72±0.02, 0.54±0.01)( P<0.05), and inhibited the activity of YAP/TEAD luciferase.At the same time, NVP-TNKS656 up-regulated two major negative regulators of YAP, namely AMOTL1 and AMOTL2 proteins, and promoted the apoptosis of HLE and HLF cells in a dose-dependent manner. Conclusion:NVP-TNKS656 can inhibit the proliferation of HCC by stabilizing AMOTL1/ AMOTL2 and down-regulating the YAP target gene.This study indicates that NVP-TNKS656 can be used as a potential drug for treating HCC.
