目的总结老年胃癌的临床特点及围手术期处理经验。方法回顾性分析我院1990年1月至2003年1月间共收治的370例老年胃癌患者的临床资料。结果370例老年胃癌中290例（78.4%）伴有高血压、心脏病、糖尿病等老年常见病； 术后发生并发症110例次，死亡16例； 手术前有共存病者术后并发症的发生率（34.5%）明显高于无共存病者（12.5%），P＜0.01。结论加强围手术期处理是降低老年胃癌患者并发症和死亡率的关键。
目的 评价肿瘤细胞减灭术治疗复发上皮性卵巢癌（EOC）的作用，分析影响生存时间的因素。 方法 按Cochrane系统评价方法，计算机检索PubMed、EMbase、Medline、Cochrane Library、循证医学数据库（EBMR）、中国生物医学文献数据库（CBM）、中国期刊全文数据库（CJFD）、清华同方等数据库，并手工检索相关领域杂志。检索时间从1985年1月1日－2011年11月30日，查找手术治疗复发EOC患者的回顾性、非随机前瞻性、病例对照研究，由两位研究者按照纳入排除标准筛选文献、评价质量并提取资料后，采用SPSS软件进行线性回归分析。 结果 共纳入48篇文献（回顾性文献40篇，非随机前瞻性文献7篇，病例对照研究1篇）共2 605例。简单线性回归分析结果显示满意切除比例与中位生存时间回归模型成立，有统计学意义（F=7.346，P=0.009），浆液性病理类型比例与中位生存时间回归模型成立，有统计学意义（F=5.537，P=0.025），残留病灶大小与中位生存时间回归模型成立，有统计学意义（F=4.249，P=0.045），多重逐步线性回归分析显示仅有满意切除比率对术后中位生存时间的影响有统计学意义（P=0.009）。 结论 二次肿瘤细胞减灭术主要适用于铂类敏感型可切除及孤立结节复发EOC患者，要获得明确二次肿瘤细胞减灭术治疗复发EOC对中位生存时间的影响，尚需进行大样本随机对照的研究。
In recent years, more and more studies have shown that obstructive sleep apnea hypopnea syndrome (OSAHS) and metabolic syndrome are closely related and interact with each other, while hypertension, abnormal glucose metabolism, lipid metabolism disorders and obesity, as the main components of metabolic syndrome, have been further studied. Continuous positive airway pressure is currently the main treatment for OSAHS. This review focuses on the association between OSAHS and hypertension, glucose metabolism abnormalities, lipid metabolism disorders, obesity and the effects of treatment with positive airway pressure, aiming to provide a theoretical basis for the pathogenesis and treatment of OSAHS complicated with metabolic syndrome.
Objective To analyze the characteristics of intestinal flora in patients with allergic asthma, so as to provide a theoretical basis for the development of new clinical treatment methods. Methods Fecal samples were collected from 14 patients with allergic asthma and 15 healthy people between January 2021 and December 2021, and 16S rRNA was used to analyze the composition and diversity of intestinal flora of the participants. Results There was no statistically significant difference in age, gender, BMI, or smoking history between the allergic asthma group and the control group (all P>0.05). Alpha diversity results showed that there was significant difference in the abundance of intestinal flora between the two groups, but there was no significant difference in the diversity of intestinal flora between the two groups. The results of β diversity analysis indicated that there were significant differences in the composition of bacterial flora between the allergic asthma group and the control group. The difference bacteria between the two groups at the genus level are Faecalibacterium, Roseburia, Alistipes, Sphingomonas, Dorea, Ruminococcaceae_UCG-002, Streptomyces, [Eubacterium]_venturiosum_group, Butyriococcus and Agathobacter. Conclusion Compared with healthy individuals, patients with allergic asthma have undergone significant changes in the composition of their gut microbiota, with various differential bacteria present. Among them, Roseburia and Eubacterium may be involved in the pathogenesis of allergic asthma through changes in short chain fatty acids.
ObjectiveTo investigate the effectiveness of concealed penis correction surgery based on the principle of midline symmetry.MethodsBetween January 2016 and September 2018, 18 children with concealed penis were treated with correction surgery based on the principle of midline symmetry. All children were 3-12 years old, with an average age of 8.3 years. Physical examination showed that the penis was short; the penis body could not be exposed or be exposed too limited; the corpus cavernosum developed well. The pressure dressing was removed at 3 days after operation and the urethral tube was removed. The color of the glans, the swelling and congestion of penis and scrotum, and the blood supple of the prepuce flap were observed.ResultsThe operation time ranged from 47 to 54 minutes, with an average of 50 minutes. All children were followed up 3 months after operation. There was no hemorrhage and necrosis of the glans and no infection or ischemic necrosis of the flap. All patients had different degree of prepuce edema at 3 days after operation, 5 patients still had prepuce edema at 2 weeks, and the prepuce edema in all patients subsided at 3 months. All penises were exposed well after midline symmetric anastomosis with no bulky prepuce and scrotum.ConclusionThe correction surgery based on the principle of midline symmetry can be used to correct the appearance of the concealed penis effectively.
