缺牙间隙对美学区水平骨增量延期种植的临床效果影响研究

目的:评价不同缺牙间隙大小对上前牙区连续缺牙伴水平骨量不足、行水平骨增量延期种植的临床效果影响.方法:回顾性分析2013年1月～2019年6月期间,于烟台市口腔医院种植科就诊,上颌前牙连续缺失,行水平骨增量延期种植的患者,根据缺牙间隙分为两组,A组为2颗牙连续缺失,B组为3～6颗牙连续缺失.通过Mimics软件重建骨增量区3D模型,测量骨增量的体积及宽度;通过Image J软件测量平行投照根尖片种植体周围边缘骨丧失高度.使用SPSS 26.0软件,对测得的结果进行统计分析,P<0.05为差异具有统计学意义.结果:纳入44例患者,年龄18～60(平均38.52±12.56)岁.共计122个位点,植入94枚种植体,其中A组44枚,B组50枚.A、B组每牙位骨增量体积差异无统计学意义(P>0.05);A组每牙位骨增量宽度小于B组每牙位骨增量宽度(P<0.05);种植体周围骨质丧失高度随时间变化而增加(P<0.05);组别对种植体近中及远中骨边缘丧失高度的影响差异无统计学意义(P>0.05).结论:美学区水平骨增量延期种植可获得满意的临床效果,缺牙间隙对对骨增量体积及种植体周围边缘骨质稳定性无影响.     

A Phase I Dose Escalation Study of the Safety,Tolerability, and Pharmacokinetics of Ipilimumab in Chinese Patients with Select Advanced Solid Tumors

Lessons Learned

• The overall safety profiles of ipilimumab 3 mg/kg and 10 mg/kg administered every 3 weeks, were consistent between Chinese patients with solid tumors in the current study and patients from previous U.S. ipilimumab monotherapy studies. No new safety signals were identified.
• The mean systemic exposures to ipilimumab (assessed by first dose area under the curve during the dosing interval and maximum serum concentration) were numerically lower in the Chinese patient population than in U.S. patients for both 3 mg/kg and 10 mg/kg doses; however, the range of serum concentrations in the Chinese and U.S. populations overlapped (3 mg/kg and 10 mg/kg), suggesting that ipilimumab pharmacokinetics was ethnically insensitive in this study.

BackgroundThis phase I, open‐label study assessed ipilimumab safety, tolerability, pharmacokinetics (PK), immunogenicity, and antitumor activity in Chinese patients with unresectable, metastatic, recurrent malignant melanoma (MM) or nasopharyngeal carcinoma (NPC).MethodsOf 39 patients enrolled, 25 received ipilimumab (11 patients received 3 mg/kg, and 14 patients received 10 mg/kg). Reasons for not receiving treatment were withdrawal of consent (3 patients), no longer meeting the criteria (10 patients), and one recorded as “other.” During the induction phase, patients received ipilimumab (3 mg/kg, i.v.), on day 1 of a 3‐week cycle, to a maximum of four doses or progressive disease (PD). During the maintenance phase at week 24, patients received ipilimumab (3 mg/kg, i.v.) on day 1 of a 12‐week cycle, to a maximum of 3 years or PD. Considering the co‐primary safety and PK endpoints, the successive dosing required nine patients with two or fewer dose‐limiting toxicities during the 42‐day observation period to proceed with a new cohort of nine patients at 10 mg/kg.ResultsIpilimumab safety and PK profiles were similar in Chinese and predominantly White populations. Ipilimumab was well tolerated. Most adverse events (AEs) were grades 1–2 and experienced by 11 patients treated with 3 mg/kg and 14 patients treated with 10 mg/kg. There were no new safety concerns. Incidence of anti‐ipilimumab antibodies was low (1 of 10 in the 3 mg/kg patients and 2 of 13 in the 10 mg/kg patients) and without safety implications. In the 3 mg/kg group, 8 of 11 patients had PD. In the 10 mg/kg group (all NPC, 0 MM patients), 11 of 14 patients had PD. Three patients had stable disease (one at 3 mg/kg and two at 10 mg/kg).ConclusionIpilimumab was well tolerated in Chinese patients, showing similar safety and PK to previous studies in predominantly White populations.     

Zhang Weishen: A Pioneer in the Development and Industrial Production of Penicillin in New China

The research and development of penicillin started with difficulty before 1949 and achieved certain results. In 1951, after the founding of the People's Republic of China, Zhang Weishen, as the only Chinese scientist who had been trained and worked in a penicillin research and development center in the United States for many years, overcame many difficulties and returned to China. In 1953, with the efforts of Zhang Weishen and his colleagues, China realized the industrialized production of penicillin, alleviating the urgent needs of the masses. Antibiotics has also become the first discipline to achieve major scientific and technological achievements after the founding of the New China. In the mid-1950s, the technical breakthrough in the localization of lactose substitutes marked the localization of the raw materials of the penicillin-producing culture medium, which paved the way for the industrialized production of penicillin with Chinese characteristics. Antibiotics have become one of the most widely used and affordable drugs for hundreds of millions of patients in China, and China has since ended the humiliating history of the “Sick Man of East Asia".

从湿热体质论治脂溢性脱发

中医对于脂溢性脱发，传统多按"血热风燥""血虚风燥""湿热""肝肾不足"等分型论治，虽能取得一定的临床疗效，暂时缓解病情，但难以根治，给患者带来困扰。倪诚教授根据国医大师王琦教授所提出的"肤-体相关论""体质可调论"，认为湿热体质是脂溢性脱发发病的主要土壤，指出瘀浊蛀发是脂溢性脱发的病机要点，治疗上以清利湿热调体治本、凉血活血为主、佐以滋养肝肾，方用茵陈蒿汤合升降散加减配合外洗经验方，从标本兼顾、分期论治、内服外洗等方面治疗脂溢性脱发，在临床上取得良好的疗效。     

不同丙戊酸负荷量对癫痫持续状态的治疗效果分析

目的了解不同丙戊酸负荷量对癫痫持续状态患儿的治疗效果。方法收集2013年1月1日至2017年12月31日在浙江大学医学院附属儿童医院重症监护室住院治疗的癫痫持续状态患儿的病例资料,根据丙戊酸负荷量进行分组,了解各组患儿癫痫持续状态的控制情况。结果(1)66例癫痫持续状态患儿,包括癫痫36例(54.5%),颅内感染16例(24.2%),缺氧窒息3例(4.5%),颅内肿瘤2例(3.0%),脑发育异常2例(3.0%),颅内出血2例(3.0%),病因不明确5例(7.6%)。(2)所有癫痫持续状态患儿根据不同的丙戊酸负荷量(0 mg/kg,10~15 mg/kg,16~39 mg/kg,40 mg/kg)分为4组,各组间的性别、年龄差异无统计学意义,癫痫持续状态控制时间和癫痫控制情况差异无统计学意义(P=0.402、0.340)。(3)所有患儿予丙戊酸钠应用后都有监测肝功能,无一例患儿出现肝功能损害的表现。结论不同丙戊酸负荷量对于癫痫持续状态患儿的治疗效果无明显差异,并且接受负荷量为40 mg/kg治疗的癫痫持续状态患儿未出现相关不良反应。
