中新网评：美国众议长选举“连续剧”暴露美式民主痼疾******

　　中新网北京1月9日电(蒋鲤)在15轮投票表决后，美国众议院议长选举这场“连续剧”终于落下帷幕，众议院共和党领袖凯文·麦卡锡最终成功当选第55任美国众议院议长。这是美国国会过去164年来耗时最久的一次议长选举记录，将美国“对抗式民主”的弊端暴露无遗。

　　由于两党对立加剧、党派内斗、利益分配不均等因素，众议长选举陷入一场拉锯战。在此次众议长竞选中，美国民主党议员继续抱团，多轮投票中，一票不投麦卡锡，共和党右翼“强硬派”领头的约20人小团体也拒绝投票麦卡锡。

　　麦卡锡的当选之路一波三折，除了本人的“政治投机派”角色在国会不受欢迎外，与共和党内部政治分歧关系密切。

　　一方面，共和党党内反对者认为，麦卡锡对民主党态度过于软弱，无力对抗民主党控制的参议院和拜登政府，另一方面，因为共和党的多数优势微弱，党内一些影响力较小的派系的政治力量则被放大，有利于他们巩固自己的选票。

　　此外，党内反对者也认为，自己的选票没有换取更多利益，希望以此作为筹码换取麦卡锡更大的让步，比如让他们获得众议院重要委员会中的职务。

　　作为仅次于美国总统、副总统的政坛三号人物，众议院议长通常由众议院多数党领袖担任，选举几乎没有悬念。然而，麦卡锡此次为当选，不得不做出多个关键让步，其中可能包括恢复一项罢黜议长动议机制，使得众议长的权力被削弱，难以掌控众议院。

　　美国有线电视新闻网CNN称，麦卡锡在这场不合时宜的政治勒索中作出让步，这种绥靖政策只会让极端主义势力更加强大。

　　这场引发全世界围观的尴尬选举暴露出美国政治存在严重的对立和分化。在权力博弈思维的裹挟下，党派利益凌驾于国家和人民利益之上，美国两党相互拆台，陷入“为反对而反对”的无脑对垒。而即便是一党内，也会因为利益分配问题产生不同的小派系，相互对抗，选票变成了谋利益的工具。

　　从国会山骚乱到打破记历史记录的15轮众议长选举，“对抗式民主”让美国政治陷入瓶颈，长期对抗势必会让政客们丧失客观公正的判断能力，其政治阶层是否有能力治理国家也会引发质疑。

　　两党之争和党派内斗进一步放大了美国政治体制弊病，美国所谓的“民主”形象，让全世界大跌眼镜。鼓吹以选民利益为先的美式选举，变成了政客们利益置换的游戏，进一步彰显出美国“民主政治”日渐失能，不断极化的党争已使美国政治制度陷入死循环。

　　House speaker election reveals deep-rooted problems in U.S. democracy

　　(ECNS) -- The Republican leader Kevin McCarthy was elected as the 55th speaker of the U.S. House of Representatives after 15 ballots. As the most grueling House speaker election in the past 164 years, the election has highlighted the defects of the country’s "confrontational democracy".

　　The election once reached a stalemate due to intense partisan strife, inner-party struggle among the Republicans, uneven distribution of interests, and more. Democratic Party members forged a close alliance, refusing to vote for McCarthy, while about 20 Republicans also declined to cast ballots for the GOP leader.

　　Except for his unpopular role as a "political speculator" in Congress, McCarthy’s hard-won election can be attributed to turmoil within the Republican Party.

　　On the one hand, opponents in the Republican Party believe that the GOP leader's attitude toward the Democrats is too weak to confront the Senate controlled by Democrats and the Biden administration.

　　On the other hand, the political power of some less influential factions in the Republican Party has been amplified due to the Party’s weak majority advantage in the House of Representatives, which is conducive to consolidating their ticket warehouses.

　　Meanwhile, these opponents believe that their votes failed to win them more benefits, hoping to use this as a bargaining chip for McCarthy's further concessions, such as getting them positions in important House Committees.

　　As the third political figure after the President and Vice President of the U.S., the speaker, by tradition, is the head of the majority party in the House of Representatives.

　　But McCarthy has made many concessions in order to bring the ultra conservatives along, involving what’s known as the “motion to vacate,” a mechanism by which members can force a vote to depose the speaker. The reported concessions will empower individual members at the expense of McCarthy’s sway as speaker.

　　CNN thought the concessions he made during this unseemly political shakedown would only make the extremist faction more powerful.

　　This embarrassing election, which has drawn global attention, exposed the serious opposition and polarization in American politics. Both Democrats and Republicans put their interests before that of the country and its people, attacking and opposing each other irrationally.

　　Besides, different factions arise within a single party and confront each other because of the distribution of interests. Votes have become a tool to win more benefits.

　　From Capitol riots to the House Speaker election with record-breaking ballots, "confrontational democracy" has become a bottleneck of American politics. Long-term confrontation will surely impede politicians to think objectively and fairly while their capacity of governing the country will also raise doubts among the public.

　　Both parties’ struggle and infighting among the Republicans have further amplified the defects of the American political system, with its "democratic" image shocking the world.

　　The U.S.-style election, which advocates putting voters' interests first, has become a game of interest exchange among politicians. In addition, it further demonstrates the malfunction of American "democratic politics" and the constantly polarized party struggle that has trapped the American political system into an infinite cycle.

全球首例糖尿病患者通过猪胰岛移植摆脱外源性胰岛素******

　　中新社长沙1月12日电 (付敬懿)中南大学湘雅三医院12日对外透露，经该院复查，全球首例2型糖尿病肾移植术后猪胰岛移植患者的糖化血红蛋白、餐后血糖、肾功能正常，实现了外源性胰岛素完全脱离。这是全球首例猪胰岛异种移植治疗糖尿病实现完全摆脱胰岛素，异种胰岛移植取得重要突破。

　　该患者有23年糖尿病史，即使每日使用大量外源性胰岛素，仍出现血糖代谢失控，发展为肾功能不全尿毒症，需要频繁的血液透析维持生命。2019年患者接受肾移植手术，但因糖尿病未得到控制，三年后移植肾出现了损伤。

　　2022年11月，中南大学湘雅三医院放射科教授王维团队联合移植科、内分泌科及营养科等组成胰岛移植多学科会诊(MDT)团队，在前期大量研究数据的基础上，为患者有针对性地设计了移植治疗方案。该方案核心内容为团队原始创新的技术体系，包括猪胰岛提取、免疫耐受诱导为主的新型抗排斥方案，微创手术途径及术后并发症的监测计划。

　　出院时，患者的糖尿病相关指标得到明显改善，糖化血红蛋白恢复至正常范围，由术前的9%恢复到正常的5.4%，每日外源性胰岛素总量较术前减少近一半。更重要的是，患者移植肾功能恢复正常，改变了移植术前糖尿病对移植肾的损伤效应。

　　出院后经两个月恢复，猪胰岛移植对患者糖尿病治疗的疗效进一步显现，糖化血红蛋白、肝功能、肾功能、血糖检测均维持正常水平。患者目前精神状况好，可胜任日常工作，实现了外源性胰岛素完全脱离。

　　据悉，糖尿病是严重影响人类健康的重大慢性疾病，中国糖尿病患者数量已高达约1.4亿。胰岛移植可以治愈糖尿病，人源性供体极度短缺是限制该技术应用的瓶颈，异种移植可有效解决供体短缺。(完)
