Objective To investigate the therapeutic effect and prognostic significance of lateral lymph node dissection (LPLND) in patients with lateral lymph node (LPLN) metastasis. Methods The clinicopathological data of rectal cancer patients who underwent total mesorectal excision (TME) combined with LPLND and pathologically confirmed as LPLN metastasis after operation were retrospectively analyzed. The clinicopathological characteristics and metastasis rules of patients with LPLN metastasis were discussed, and the survival prognosis after LPLND was analyzed. Results A total of 102 rectal cancer patients with pathologically confirmed LPLN metastasis were included. The common sites of LPLN metastasis were internal iliac vessels lymph nodes (n=68, 66.7%), followed by obturator lymph nodes (n=44, 43.1%), and common iliac vessels or external iliac vessels lymph nodes (n=12, 11.8%). There were 10 patients (9.8%) with bilateral LPLN metastases, and the mean number of LPLN metastases was 2.2±2.4, among which 16 patients (15.7%) had LPLN metastases number≥2. The 3-year OS (66.8% vs. 7.7%, P < 0.001) and DFS (39.1% vs. 10.5%, P=0.012) of patients with LPLN metastases to the external iliac or common iliac lymph node were significantly lower than those with metastases to the internal iliac or obturator lymph node. The multivariate analysis showed that LPLN metastasis to external iliac or common iliac lymph node was an independent risk factor both for OS (HR=3.53; 95%CI: 1.50-8.31; P=0.004) and DFS (HR=2.40; 95%CI: 1.05-5.47; P=0.037). Conclusion LPLN mainly metastasizes to the internal iliac or obturator lymph node areas. The survival of patients with metastasis to the external iliac or common iliac lymph node cannot be improved by LPLND, and thus systemic comprehensive treatment is often the optimal treatment option.

Of 59 206 patients, there were 23 104 cases with early-onset colorectal cancer and 36 102 cases with late-onset colorectal cancer, and cases aged 13-29 years, cases aged 30-34 years, cases aged 35-39 years, cases aged 40-44 years, cases aged 45-49 years, cases aged 55-59 years were 1 041, 1 740, 3 288, 6 050, 10 985, 15 303,20 799, respectively. (2) Comparison of clinicopathological charac-teristics between early-onset and late-onset colorectal cancer. ① There were significant differences in gender, tumor location, degree of tumor differentiation, tumor histological type, tumor TNM staging, tumor T staging, tumor N staging, tumor M staging, preoperative carcinoembryonic antigen (CEA), perineural invasion, cancer nodule, tumor diameter between patients with early-onset and late-onset colorectal cancer ( P<0.01). Results of further analysis showed that cases with tumor located in ileocecal region, ascending colon, colon liver region, transverse colon were 2 329, 2 139, 579, 1 303 in the 6 350 patients with early-onset right colon cancer. The above indicators were 4 563, 3 945, 902, 1 951 in the 11 361 patients with late-onset right colon cancer. There was a significant difference in the above indicators between the two groups of patients ( χ2=114.27, P<0.01). Cases with tumor located in splenic region of the colon, descending colon, sigmoid colon, rectum sigmoid junction were 553, 1 354, 6 404, 2 431 in the 10 742 patients with early-onset left colon cancer. The above indicators were 865, 1 798, 9 668, 3 610 in the 15 941 patients with late-onset left colon cancer. There was a significant difference in the above indicators between the two groups of patients ( χ2=35.60, P<0.01). ②Of 23 104 patients with early-onset colorectal cancer, cases aged 13-29 years, cases aged 30-34 years, cases aged 35-39 years, cases aged 40-44 years, cases aged 45-49 years were 1 041, 1 740, 3 288, 6 050, 10 985, respectively. There were significant differences in gender, degree of tumor differentiation, tumor histological type, tumor TNM staging, tumor T staging, tumor N staging, pre-operative CEA, perineural invasion, cancer nodule, tumor diameter among patients of different age groups ( P<0.01). Results of further analysis showed that cases with tumor located in ileocecal region, ascending colon, colon liver region, and transverse colon were 91, 117, 45, 69 in the 6 350 early-onset right colorectal cancer patients aged 13-29 years. The above indicators were 165, 136, 47, 115, 304, 313, 93,201, 614, 535, 151, 330, 1 155, 1 038, 243, 588 in early-onset right colorectal cancer patients aged 30-34, 35-39, 40-44, 45-49 years, respectively. There was a significant difference in the above indicators among the five groups of patients ( H=36.63, P<0.01). Cases with tumor located in splenic region of the colon, descending colon, sigmoid colon, rectum sigmoid junction were 32, 83, 260, 95 in the 10 742 early-onset left colorectal cancer patients aged 13-29 years. The above indica-tors were 53, 112, 452, 171, 95, 230, 867, 342, 149, 337, 1 702, 665, 224, 592, 3 123, 1 158 in the 10 742 early-onset left colorectal cancer patients aged 30-34, 35-39, 40-44, 45-49 years, respectively. There was a significant difference in the above indicators among the five groups of patients ( H=47.84, P<0.01). Conclusions:Compared with late-onset colorectal cancer, early-onset colorectal cancer are more likely to occur in the left colon and rectum, with poorly differentiated and undifferentiated tumors, histological type of mucinous adenocarcinoma, TNM staging of stage Ⅲ and Ⅳ, higher proportion of nerve infiltration and cancer nodules, and larger tumor diameter. There are significant differences in clinicopathological characteristics of tumors among patients with early-onset colorectal cancer of different age groups.

The treatment of locally advanced rectal cancer (LARC) is extremely challenging, and it is difficult to achieve satisfactory results with surgical resection alone. In recent years, the diagnosis and treatment of LARC tends to be multi-disciplinary (MDT) mode. The emerging neoadjuvant treatment strategy is a milestone. At present, the preferred treatment for LARC is neoadjuvant chemoradiotherapy combined with total mesorectal excision. This article summarizes the main treatments of LARC neoadjuvant therapy, hoping to provide reference for clinical diagnosis and treatment.

Objective:To investigate the expression of fibroblast growth factor 7 (FGF7) and related inflammatory factors in the serum of patients with acute exacerbation of chronic obstructive pulmonary disease (COPD).Methods:A case control study was conducted. The patients with AECOPD admitted to the First Affiliated Hospital of Xinjiang Medical University from November 2016 to January 2020 were enrolled. The patients were divided into mild group [forced expiratory volume in one second (FEV1)/forced vital capacity (FVC) ratio (FEV1/FVC) < 0.70, FEV1 percentage in predicted value (FEV1%) ≥ 80%], moderate group (FEV1/FVC < 0.70, 50% ≤ FEV1% < 80%), and severe group (FEV1/FVC < 0.70, 30% ≤ FEV1% < 50%) based on their lung function test results, with 20 patients in each group, and 20 patients with normal pulmonary function who underwent elective non-thoracic surgery such as gastrointestinal surgery and orthopedics surgery in the same period were selected as controls. The demographic data, FEV1/FVC, FEV1%, FVC, maximum mid-expiratory flow percentage in predicted value (MMEF%), 6-minute walking test (6MWT), and St George Respiratory Questionnaire (SGRQ) score were recorded respectively. Serum levels of FGF7, interleukins (IL-6, IL-1β) and tumor necrosis factor-α (TNF-α) were determined by enzyme linked immunosorbent assay (ELISA). Pearson correlation was used to analyze the correlation between TNF-α and lung function.Results:Compared with the normal pulmonary function group, the levels of FEV1/FVC, FEV1%, MMEF% and 6MWT in the mild, moderate and severe groups were significantly decreased, and the SGRQ scores were increased, the indicators continued to deteriorate with the aggravation of the disease, the statistical differences were found between severe group and normal pulmonary function group [FEV1/FVC: 0.39±0.09 vs. 0.81±0.04, FEV1%: (38.80±6.28)% vs. (109.58±13.80)%, MMEF%: (0.34±0.14)% vs. (2.69±0.99)%, 6MWT (m): 279.00±41.61 vs. 402.85±53.97, SGRQ scores: 34.95±6.71 vs. 2.60±2.06, all P < 0.05]. Compared with the normal pulmonary function group, the levels of FGF7 in the mild, moderate and severe groups were significantly lowered (ng/L: 6.31±2.65, 6.10±1.39, 6.64±1.77 vs. 8.29±3.51, all P < 0.05), but no significant difference was found among the mild, moderate and severe groups (all P > 0.05). Compared with the normal pulmonary function group, IL-6 and TNF-α levels were significantly increased in the mild, moderate and severe groups, and TNF-α increased with the aggravation of the disease, the statistical difference was found between severe group and normal pulmonary function group (ng/L: 7.42±2.28 vs. 3.83±0.92, P < 0.05). There was no significant difference in IL-1β level between the normal pulmonary function group and the mild, moderate, severe groups. Correlation analysis showed that TNF-α was negatively correlated with FEV1/FVC and FEV1% ( r values were -0.350 and -0.527, respectively, both P < 0.01). Conclusion:In AECOPD patients, serum FGF7 was decreased, while IL-6 and TNF-α were increased; however, with the aggravation of the disease, there was no significant change in the level of FGF7 in the peripheral blood, but the TNF-α level might be increased, accompanied by severe damage of small airway function.
