Objective To investigate the pathological and clinical significance of 12 cases with primary Lymphoepithelioma-like carcinoma of the lung (LELC). Methods Retrospectively detectded and analyzed the clincalpathological feature of 12 cases of LELC of the lung. Results Histological study showed that tumor cells were significantly expressed HCK by immunohistochemistry staining and showed out 91.7% positive rate of EBER by situ hybridization. In this series, the median survival time was 61.3 months. The overall 2 and 5 year survival rates of the 12 cases were 84.6% and 57.7%. Conclusion Pulmonary LELC is very rare. It may be associated with Epstein-Barr virus infection, and has a batter prognosis after therapy.

目的 探讨DPP-4抑制剂联合二甲双胍治疗2型糖尿病的临床疗效及安全性。方法 选取医院近3年收治的糖尿病病人70例,随机分为对照组(35例)和治疗组(35例),对照组给予二甲双胍治疗,治疗组给予二甲双胍联合DPP-4抑制剂控制血糖,经3个月治疗,比较治疗后血糖指标、胰岛功能指标及低血糖、不良反应情况。结果 对照组和治疗组治疗后FPG、2hPG、HbA1c水平均有降低,治疗组治疗后血糖检测指标优于对照组(P＞0.05)。胰岛功能监测显示治疗组治疗后空腹胰岛素、服糖后2小时胰岛素浓度升高优于对照组,胰高血糖素水平降低幅度大于对照组,治疗前后胰岛素及胰高血糖素均有变化,组间比较P＞0.05,有临床意义。治疗期间两组患者均未发生低血糖、药物不良反应。结论 DPP-4抑制剂联合二甲双胍可显著提高降糖效果,改善胰岛功能,并且无低血糖、药物不良反应发生。

目的 评估CO₂激光治疗宫颈上皮内瘤变Ⅱ级（CIN2）病例的疗效。方法 收集2021年11月至2023年10月在本院行CO2激光治疗的92例CIN2患者的临床资料, 采用液基细胞学检查（LCT）和人乳头状瘤病毒（HPV）联合筛查随访,随访6~12个月, 任一结果异常者转诊阴道镜检查, 必要时行病理活组织检查（活检）观察鳞状上皮内病变情况。结果 92例CIN2患者中, 年龄25~45岁、有人工流产史、性伴侣人数3个及以上、因发现宫颈病变就诊者占比较多,患者均未生育。所有患者就诊时均发现HPV阳性, 20.65%患者报告HPV16阳性, HPV18阳性者占比1.09%, HPV其他12种阳性占60.87%, HPV16阳性伴其他12种阳性占17.39%。79例患者随访6个月后总HPV+LCT均阴率为74.68%（59/79）,LCT和HPV阴转率分别为92.41%（73/79）和74.68%（59/79）。所有患者术后12个月LCT均转阴。29例患者在术后12个月均无病变持续或病变发展。25岁以下患者术后6个月及12个月HPV持续率最低, 45~55岁患者术后HPV持续率最高,且多发生HPV16阳性及合并其他HPV亚型阳性的情况。结论 CO₂激光治疗可提高患者术后HPV与LCT阴转率, 所有患者术后6个月及12个月随访均无病变加重,且可明显改善年轻患者HPV感染情况。对于有生育要求且具备适应证的CIN2患者, 应积极采取CO₂激光治疗以获得更高健康收益。

Objective To evaluate the therapeutic efficacy of CO₂ laser treatment in cervical intraepithelial neoplasia grade 2（CIN2）patients. Methods We retrospectively analyzed data from 92 CIN2 patients who underwent CO₂ laser therapy at the institution from November 2021 to October 2023. Postoperative followed-up for 6-12 months, screening with liquid-based cytopathology test（LCT）and high-risk human papilloma virus（HPV）testing. Patients with abnormal results in either test were referred for colposcopy, with biopsy performed to evaluate residual or recurrent squamous intraepithelial lesions. Results Among total of 92 patients, most patients aged 25-45 years old, with a history of induced abortion, had three or more sexual partners, and visited hospital due to cervical lesions, and none of the patients gave birth. All patients were found to be HPV positive at hospital visits, with 20. 65% of HPV16 positive, 1. 09% of HPV18 positive, 60. 87% of other 12 kinds HPV positive, while HPV16 positive with other 12 kinds accounted for 17. 39%. Among the 79 patients after 6-month follow-up, the dual-negative conversion rate（HPV+LCT）was 74. 68%（59/79）, with LCT and HPV negative rates reaching 92. 41%（73/79）and 74. 68%（59/79）, respectively. After 12-month follow-up, all patients achieved LCT negativity, 29 patients with no documented lesion persistence or disease progression. Notably, patients aged <25 years exhibited the lowest postoperative HPV persistence rates between 6- to 12-month follow-up, whereas those aged 45-55 years demonstrated the highest persistence rates, frequently associated with HPV16 positivity or co-infection with other HPV subtypes. Conclusions CO₂ laser therapy significantly increases postoperative negative conversion rates for HPV and LCT. No lesion progression was observed in patients between 6- to 12-month follow-ups. The therapy also notably improves HPV clearance in younger patients. For patients with CIN2 who have fertility requirements and meet the indications, CO2 laser therapy should be actively adopted to achieve greater health benefits.

目的 探讨抗增殖蛋白2（PHB2）脓毒症心肌损伤线粒体功能的调控机制。方法 体外培养大鼠心肌细胞株（H9C2）,分为对照组、脂多糖（LPS）组、LPS+PHB2 siRNA（si-PHB2）组。检测氧化应激指标细胞内丙二醛（MDA）水平、荧光探针检测细胞内活性氧（ROS）水平;线粒体指标：三磷酸腺苷（ATP）水平、线粒体膜电位、线粒体电镜、线粒体半定量评分;免疫印迹法检测PHB2、PTEN诱导激酶1（PTNKI）、帕金蛋白（Parkin）、线粒体转录因子（TFAM）的表达。结果 LPS刺激后MDA水平和ROS水平升高、ATP水平低,LPS+si-PHB2组MDA（6.21±0.39 vs 3.59±0.33, P<0.05）、细胞内的ROS（15 131.37±88.72 vs 8 628.67±71.95, P<0.05）的水平较LPS组升高,ATP（3.46±0.34 vs 4.52±0.25, P<0.05）和线粒体膜电位水平（0.33±0.04 vs 0.55±0.09, P<0.05）进一步降低;电镜观察显示与正常组相比,LPS组、LPS+si-PHB2组出现不同程度线粒体损伤,线粒体损伤半定量评分显示LPS+si-PHB2组的损伤较LPS组更为明显（1.42±0.10 vs 0.81±0.04, P<0.05）; 免疫印迹法结果显示LPS处理后PHB2、PINK1、Parkin 表达上调,TFAM表达下调,LPS+si-PHB2组的线粒体自噬相关蛋白PINK1（1.33±0.06 vs 1.79±0.21, P<0.05）、Parkin（1.43±0.08 vs 1.86±0.09, P<0.05）和线粒体生物发生关键蛋白TFAM（0.29±0.01 vs 0.74±0.06, P<0.05）表达均较LPS组降低。结论 LPS可促进大鼠心肌细胞PHB2表达,si-PHB2干扰后线粒体自噬蛋白和生物发生蛋白表达抑制,心肌细胞氧化应激损害和线粒体功能障碍加重,提示PHB2表达上调可能恢复线粒体稳态改善脓毒症心肌损伤的线粒体功能。

Objective To explore the regulatory mechanism of septic myocardial injury by prohibitin 2（PHB2）. Methods Rat myocardial cell lines（H9C2）were cultured in vitro and divided into control group,LPS group,LPS + PHB2 siRNA（si-PHB2） group. The indicators for detecting oxidative stress include the levels of intracellular malondialdehyde（MDA）and reactive oxygen species（ROS）. The indicators for mitochondrial detection include adenosine triphosphate（ATP）levels,mitochondrial membrane potential,mitochondrial electron microscopy,and semi-quantitative mitochondrial scoring. Western blotting was used to detect the expression of PHB2,PTEN induced putative kinase（PINK1）,Parkin,mitochondrial transcription factor A（TFAM）. Results After LPS stimulation,MDA level and intracellular ROS level increased,ATP level decreased. Compared with LPS group,MDA（6. 21±0. 39 vs 3. 59±0. 33, P<0. 05）level and intracellular ROS level（15 131. 37±88. 72 vs 8 628. 67±71. 95, P<0. 05）in LPS + si-PHB2 group increased significantly,while ATP（3. 46±0. 34 vs 4. 52±0. 25, P<0. 05）and MMP（0. 33±0. 04 vs 0. 55±0. 09, P<0. 05）level further decreased. Compared with the normal group,the structure of mitochondria in LPS group and LPS + si-PHB2 group was damaged in different degree. The semi-quantitative score of mitochondrial damage showed that the damage in LPS + si-PHB2 group was more obvious than that in LPS group（1. 42±0. 10 vs 0. 81±0. 04, P<0. 05）. Western blotting showed that the expression of PHB2,PINK1 and Parkin were up-regulated and the expression of TFAM was down-regulated after LPS treatment,mitohagy-related proteins PINK1（1. 33±0. 06 vs 1. 79±0. 21, P<0. 05）,Parkin（1. 43±0. 08 vs 1. 86±0. 09, P<0. 05）and mitochondrial biogenetic protein TFAM（0. 29±0. 01 vs 0. 74±0. 06, P<0. 05）in LPS+si-PHB2 group were lower than those in LPS group. Conclusions LPS can promote the expression of PHB2 in rat cardiomyocytes. After interfering with PHB2 expression,we found that mitochondrial autophagy and biogenesis are inhibited,and mitochondrial dysfunction,oxidative stress exacerbated,suggesting that the up-regulation of PHB2 expression may restore mitochondrial homeostasis and improve mitochondrial function in septic myocardial injury.

       目的   探讨谷氨酸对HT22细胞线粒体自噬和细胞凋亡的影响，并评估虾青素预处理的保护作用及其分子机制。方法   用谷氨酸及虾青素处理HT22细胞，通过蛋白印迹及聚合酶联反应等评估其对线粒体自噬的影响。结果   谷氨酸处理显著抑制线粒体初级自噬（PINK1、Parkin、pULK1^ser555和LC3Ⅱ）和次级自噬（LAMP1和Rab7），上调cleaved Caspase-3的表达（P＜0.05）。虾青素预处理减少细胞凋亡，恢复了线粒体自噬，PINK1、Parkin、pULK1^ser555和LC3Ⅱ的表达水平上升（分别为2.3倍、2.6倍、83.3%及81.1%）（P＜0.05），该作用被自噬抑制剂BafA1阻断。此外，谷氨酸抑制Nrf2核内转移和NLRX1表达，而预处理显著促进Nrf2的核内转移并上调NLRX1，分别上调25.8%、33.2%。生物信息学分析显示NLRX1启动子区域含有3个Nrf2结合位点，提示Nrf2通过调控NLRX1转录活性发挥作用。结论   文章揭示虾青素通过Nrf2/NLRX1通路激活线粒体自噬，展现神经保护作用。
