[摘 要] 目的：探讨长链非编码RNA 01694（LINC01694）调节miR-128-3p/端粒重复结合因子1（TERF1）轴对前列腺癌（PC）细胞恶性生物学行为的影响。方法：收集2023年1月至2024年1月间在荆州市中心医院泌尿外科手术切除的20例PC组织及相应癌旁组织，常规培养人PC细胞PC-3、DU145、LNCaP、C4-2和正常人前列腺上皮细胞RWPE-1。用Lipo6000TM转染试剂将sh-LINC01694、sh-NC、miR-128-3p inhibitor、inhibitor-NC、miR-128-3pmimics、pcDNA和pcDNA-LINC01694转染LNCaP细胞，分为Ctrl、sh-NC、sh-LINC01694、sh-LINC01694 + NC inhibitor、sh-LINC01694 + miR-128-3p inhibitor、pcDNA和pcDNA LINC01694组。用qPCR法检测PC组织和细胞，以及各组LNCap细胞中LINC01694、miR-128-3p和TERF1 mRNA的表达，WB法检测各组LNCaP细胞中TERF1、caspase-3、cyclin D1、E-cadherin、N-cadherin蛋白的表达，克隆形成实验、流式细胞术和Transwell小室实验分别检测各组LNCaP细胞的增殖、迁移、侵袭能力，以及细胞凋亡情况。双萤光素酶报告基因实验、RNA pull-down实验和RNA免疫共沉淀（RIP）实验验证LINC01694与miR-128-3p和TERF1与miR-128-3p的靶向结合关系。裸鼠LNCaP细胞移植瘤实验检测敲减LINC01694对其移植瘤生长的影响。结果：LINC01694在PC组织、细胞中呈高表达（均P < 0.05），在LNCaP细胞中敲减LINC01694可促进miR-128-3p、caspase-3、E-cadherin蛋白的表达，抑制LINC01694、TERF1、cyclin D1、N-cadherin蛋白的表达，抑制LNCaP细胞的增殖、迁移和侵袭能力，并促进其凋亡（均P < 0.05），这些作用均可被miR-128-3p inhibitor部分逆转（均P < 0.05）。LINC01694可直接与miR-128-3p结合（P < 0.05），miR-128-3p可直接与TERF1mRNA结合（P < 0.05），说明LINC01694可调控miR-128-3p/TERF1轴。敲减LINC01694可明显抑制裸鼠LNCaP细胞移植瘤的生长（P < 0.05）。结论：LINC01694通过调节miR-128-3p/TERF1轴抑制LNCaP细胞的恶性生物学行为。

Objective To evaluate the value of multi-slice spiral computed tomography (CT) for diagnosing acute pulmonary embolism, and to provide a reference for the precise diagnosis of acute pulmonary embolism. Methods We enrolled a total of 102 patients pathologically diagnosed with acute pulmonary embolism from January 2019 to October 2023. All the patients underwent CT scanning of central and segmental pulmonary arteries with a GE 64-slice spiral CT scanner. The diagnostic efficacy of multi-slice CT scans for acute pulmonary embolism was evaluated with the pathological results as the gold standard. Results Of the 102 patients pathologically diagnosed with acute pulmonary embolism, multi-slice CT detected 92 cases, with an accuracy of 90.20% (92/102), including 17 cases (18.48%) of embolism in left pulmonary arteries, 31 cases (33.70%) of embolism in right pulmonary arteries, and 44 cases (47.82%) of embolism in both pulmonary arteries. Multi-slice CT visualized a total of 9905 pulmonary artery branches, and 304 of them (3.07%) had embolism, with the highest embolism rate in lobar arteries (43.89%). Conclusion Multi-slice spiral CT has high accuracy for diagnosing acute pulmonary embolism by directly and clearly visualizing embolism in the arteries of the lungs, which deserves clinical promotion.

Objective: To investigate the incidence and treatment of perioperative anemia in patients with gastrointestinal neoplasms in Hubei Province. Methods: The clinicopathological data of 7 474 patients with gastrointestinal neoplasms in 62 hospitals in 15 cities (state) of Hubei Province in 2019 were collected in the form of network database. There were 4 749 males and 2 725 females. The median age of the patients was 62 years (range: 17 to 96 years). The hemoglobin value of the first time in hospital and the first day after operation was used as the criterion of preoperative anemia and postoperative anemia. Anemia was defined as male hemoglobin <120 g/L and female hemoglobin <110.0 g/L, mild anemia as 90 to normal, moderate anemia as 60 to <90 g/L, severe anemia as <60 g/L. The t test and χ² test were used for inter-group comparison. Results: The overall incidence of preoperative anemia was 38.60%(2 885/7 474), and the incidences of mild anemia, moderate anemia and severe anemia were 25.09%(1 875/7 474), 11.37%(850/7 474) and 2.14%(160/7 474), respectively. The overall incidence of postoperative anemia was 61.40%(4 589/7 474). The incidence of mild anemia, moderate anemia and severe anemia were 48.73%(3 642/7 474), 12.20%(912/7 474) and 0.47%(35/7 474), respectively. The proportion of preoperative anemia patients receiving treatment was 26.86% (775/2 885), and the proportion of postoperative anemia patients receiving treatment was 14.93% (685/4 589). The proportions of preoperative anemia patients in grade ⅢA, grade ⅢB, and grade ⅡA hospitals receiving treatment were 26.12% (649/2 485), 32.32% (85/263), and 29.93% (41/137), and the proportions of postoperative anemia patients receiving treatment were 14.61% (592/4 052), 22.05% (73/331), and 9.71% (20/206). The proportion of intraoperative blood transfusion (16.74% (483/2 885) vs. 3.05% (140/4 589), χ²=434.555, P<0.01) and the incidence of postoperative complications (17.78% (513/2 885) vs. 14.08% (646/4 589), χ²=18.553, P<0.01) in the preoperative anemia group were higher than those in the non-anemia group, and the postoperative hospital stay in the preoperative anemia group was longer than that in the non-anemia group ((14.1±7.3) days vs. (13.3±6.2) days, t=5.202, P<0.01). Conclusions: The incidence of perioperative anemia in patients with gastrointestinal neoplasms is high. Preoperative anemia can increase the demand for intraoperative blood transfusion and affect the short-term prognosis of patients. At present, the concept of standardized treatment of perioperative anemia among gastrointestinal surgeons in Hubei Province needs to be improved.

OBJECTIVE: To detect the levels of Treg, Th17, Th9 cells and expression of transforming growth factor-β (TGF-β), interleukin-17 (IL-17) and interleukin-9 (IL-9) in peripheral blood of patients with immune thrombocytopenia (ITP) and to explore its role in the pathogenesis of ITP. METHODS: Fifty-four patients with ITP (ITP group) and 40 healthy volunteers (control group) were selected in our hospital. The of Treg, Th17 and Th9 cells in peripheral blood of 2 groups were measured by flow cytometry, and the expression of cytokines, such as TGF-β, IL-17 and IL-9 in the peripheral blood of 2 groups were detected by enzyme linked immunosorbent assay (ELISA). RESULTS: The level of Treg cells in the peripheral blood of the ITP group was significantly decreased in comparison with the control group, while the levels of Th17 and Th9 cells significantly increased in comparison with the control group (all P<0.01). The expression of cytokine such as TGF-β in the peripheral blood of the case group significantly decreased in comparison with the control group, while the expression levels of IL-17 and IL-9 significantly increased in comparison with the control group (P<0.01). The results of Pearson correlation analysis showed that there was a positive correlation between the level of Treg cells and platelet count (PLT) in peripheral blood of the ITP group (r=0.35, P<0.05), and there were negative correlation between the level rate of Th17, Th9 cells and Plt count (r=-0.37, -0.43, P<0.05); there was a positive correlation between the expression of the TGF-β in the ITP group and Plt count (r=0.46, P<0.05), while the expression of IL-17 and IL-9 showed negative correlation with PLT (r=-0.48, -0.54, P<0.05). CONCLUSION The percentage of Treg, Th17 and Th9 cells in the peripheral blood of patients with ITP is abnormal, and the expression of TGF-β, IL-17 and IL-9 also is abnormal, which may play an important role in the pathogenesis of ITP.

OBJECTIVE: To analyze the relation between the signle nucleotide polymorphisms (SNP) of CYP3A5 gene and MDR1 gene loci and the risk of cytogenetic relapse in chronic myeloid leukemia (CML). METHODS: The clinical data of 90 patients with CML treated with imatinib in our hospital were collected.The patients were divided into 2 groups: non-relapse and relapse according to relapse and non-relapse, then the relation between the SNP of CYP3A5 gene and MRD1 gene loci and the risk of cytogenetic relapse in CML patients. RESULTS: The grouping result showed that the patients with non cytogenetic relapse accounted for 41 cases those were enrolled in non-relapse group, and patient-with cytogenetic relapse accounted for 49 cases those were enrolled in relapse group. The follow-up time was 36 months. The detection showed that the incidence of cytogenetic relapse in the patients with CC genotype was significantly higher than that in the patients with TT+CT genotype of C3435T and C1236T at MDR1 gene loci (P<0.05).Compared with the patients with CT+CC genotype in C3435T locus of MDR1 gene, the rate of cytogenetic relapse in the patients with TT genotype decreased significantly (P<0.05). Compared with patients with CT+CC phemotype of C3435T in MDR1 gene locus, the non-relapse survival time of TT genotypes was significantly prolonged (P<0.05). Compared with non-relapse group, the incidence of neutropenia (29.27% vs 71.43%) and blood toxicity (39.02% vs 61.22%) in the relapse group increased significantly (P<0.05). The imatinib dose (OR=2 95, 95% CI:1.37~7.76) and the C3435T genotype in MDR1 genes (OR=0.09, 95% CI:0.05~0.72) were the factors affecting the cytogenetic relapse of the patients with CML (both P<0.05). CONCLUSION The therapeutic dose of imatinib and the C3435T and C1236T genotypes in MDR1 gene have a certain effect on the cytogenetic relapse of CML patients. C3435T genotypes in the.MDR1 gene showed a certain predictive value for evaluating the risk of cytogenetic relapse, which can be used as a clinical biomarker.

OBJECTIVETo explore the efficacy of partial resection of puborectalis combined with mutilation of internal anal sphincter(IAS) in the treatment of puborectalis syndrome with high anal pressure.

METHODSTwenty-five cases of puborectalis syndrome with high anal resting pressure in the preoperative examination received the operation of partial resection of puborectalis combined with mutilation of IAS in Zhongnan Hospital of Wuhan University between January 2013 and May 2015. The position of puborectalis was confirmed by touching with the exposure under the transfixion device, and a transverse incision was made by electrotome between 3 and 5 o'clock direction of puborectalis, then partial puborectalis was lifted by vessel clamp at 5 o'clock direction, and about 0.5 cm of muscular tissue was resected. Between 8 to 10 o'clock direction of anal tube, about 1 cm length of transverse incision was made by electrotome, then partial IAS was lifted by vessel clamp and cut off. Preoperative and postoperative 3-month anorectal manometry and defecography were carried out. Wexner constipation score and Cleveland Clinic incontinence score were implemented before surgery and 3, 6, 12 months after operation. This study was registered in the Chinese Clinical Trial Registry (registration number: ChiCTR-ORB-16007695).

RESULTSOf the 25 cases, 18 were male and 7 were female, the average age was 55 years old and the average course of disease was 9 years. Compared with pre-operation, the postoperative 3-month anal resting pressure and maximal squeeze pressure were significantly decreased [(53.56±9.05) mmHg vs. (92.44±7.06) mmHg, (142.80±20.35) mmHg vs. (210.88±20.56) mmHg, respectively, both P=0.000]; anorectal angulation at resting state and forced defecation state increased significantly [(102.32±4.96)degree vs. (95.88±4.01)degree, (117.88±5.95)degree vs. (89.52±3.25)degree, respectively, both P=0.000]. Wexner constipation score of postoperative 3-month, 6-month, 12-month (8.28±3.91, 7.40±3.64 and 8.04±4.74) was significantly lower than the preoperative score (16.00±3.69, all P<0.05), while the score was not significantly different among 3 time points after operation (P>0.05). Cleveland Clinic incontinence score was 0 at postoperative 6 and 12 months, and revealed 20 cases were effective among all the surgical patients(80%).

CONCLUSIONPartial resection of puborectalis combined with mutilation of internal anal sphincter can effectively reduce anal pressure and improve symptoms of outlet obstruction, which is an effective method in the treatment of puborectalis syndrome with high anal pressure.
