目的研究中国儿童肺炎链球菌脑膜炎(pneumococcal meningitis,PM)的临床特征、转归和分离菌株肺炎链球菌(Streptococcus pneumoniae,SP)的药物敏感性。方法回顾性分析2019年1月—2020年12月全国33家三级甲等医院160例<15岁的PM住院患儿的临床信息、实验室资料和微生物学资料。结果160例PM患儿中,男103例,女57例;年龄15 d至15岁,其中3月龄至<3岁109例(68.1%)。脑脊液培养分离SP菌株95例(59.4%),血培养分离SP菌株57例(35.6%)。脑脊液宏基因组二代测序和脑脊液SP抗原检测阳性率分别为40%(35/87)、27%(21/78)。55例(34.4%)患儿存在1个或多个化脓性脑膜炎高危因素;113例(70.6%)患儿有1个或多个颅外感染病灶;18例(11.3%)有明确基础疾病。临床症状以发热最常见(147例,91.9%),其次是精神萎靡(98例,61.3%)、呕吐(61例,38.1%)等。69例(43.1%)患儿住院期间发生颅内并发症,常见并发症为硬膜下积液和/或积脓(43例,26.9%)、脑积水(24例,15.0%)、脑脓肿(23例,14.4%)、脑出血(8例,5.0%)。硬膜下积液和/或积脓和脑积水主要发生在<1岁患儿,分别为91%(39/43)、83%(20/24)。SP菌株对万古霉素(100%,75/75)、利奈唑胺(100%,56/56)、厄他培南(100%,6/6)完全敏感;对左氧氟沙星(81%,22/27)、莫西沙星(82%,14/17)、利福平(96%,25/26)和氯霉素(91%,21/23)敏感率高;对青霉素(16%,11/68)、克林霉素(6%,1/17)敏感率低;对红霉素完全耐药(100%,31/31)。痊愈和好转出院率分别为22.5%(36/160)、66.2%(106/160);18例(11.3%)出现不良结局。结论儿童PM多见于3月龄至<3岁婴幼儿,颅内并发症多发生在<1岁患儿,发热是PM患儿最常见的临床表现,硬膜下积液和/或积脓、脑积水是最常见的并发症。脑脊液非培养检测方法有助于提高病原菌检出率。超过10%PM患儿出现不良结局。SP菌株对万古霉素、利奈唑胺、厄他培南、左氧氟沙星、莫西沙星、利福平、氯霉素敏感率高。

Mammalian target of rapamycin(m TOR) inhibitor as an attractive drug target with promising antitumor effects has been widely investigated. High quality clinical trial has been conducted in liver transplant(LT) recipients in Western countries. However, the pertinent studies in Eastern world are paucity. Therefore, we designed a clinical trial to test whether sirolimus can improve recurrence-free survival(RFS) in hepatocellular carcinoma(HCC) patients beyond the Milan criteria after LT. This is an open-labeled, single-arm, prospective, multicenter, and real-world study aiming to evaluate the clinical outcomes of early switch to sirolimus-based regimens in HCC patients after LT. Patients with a histologically proven HCC and beyond the Milan criteria will be enrolled. The initial immunosuppressant regimens are center-specifc for the frst 4-6 weeks. The following regimens integrated sirolimus into the regimens as a combination therapy with reduced calcineurin inhibitors based on the condition of patients and centers. The study is planned for 4 years in total with a 2-year enrollment period and a 2-year follow-up. We predict that sirolimus conversion regimen will provide survival benefts for patients particular in the key indicator RFS as well as better quality of life. If the trial is conducted successfully, we will have a continued monitoring over a longer follow-up time to estimate indicator of overall survival. We hope that the outcome will provide better evidence for clinical decision-making and revising treatment guidelines based on Chinese population data.

Background： The Food and Drug Administration recently announced that the use of morcellation may cause fibroids or pelvic dissemination and metastasis of uterine sarcoma; therefore, the use of morcellation is limited in the USA. A large sample study is necessary to assess the proportion of uterine malignant tumors found in patients with laparoscopic myomectomy. Methods： A national multicenter study was performed in China. From 2002 to 2014, 33,723 cases were retrospectively selected. We calculated the prevalence and recorded the clinical characteristics of the patients with malignancy after morcellation application. A total of 62 cases were finally pathologically confirmed as malignant postoperatively. Additionally, the medical records of the 62 patients were analyzed in details. Results： The proportion of postoperative malignancy after morcellation application was 0.18% （62/33,723） for patients who underwent laparoscopic myomectomy. Nearly 62.9% （39/62） of patients had demonstrated blood flow signals in the uterine fibroids before surgery. And, 23 （37.1%） patients showed rapid growth at the final preoperative ultrasound. With respect to the pathological types, 38 （61.3%） patients had detectable endometrial stromal sarcoma, 13 （21.0%） had detectable uterine leiomyosarcoma, only 3 （3.2%） had detectable carcinosarcoma, and 5 （8.1%） patients with leiomyoma had an undetermined malignant potential. Conclusions： The proportion of malignancy is low after using moreellation in patients who undergo laparoscopie myomectomy. Patients with fast-growing uterine fibroids and abnormal ultrasonic tumor blood flow should be considered for malignant potential, and morcellation should be avoided.

The Large sky Area Multi-Object Fiber Spectroscopic Telescope（LAMOST） general survey is a spectroscopic survey that will eventually cover approximately half of the celestial sphere and collect 10 million spectra of stars, galaxies and QSOs. Objects in both the pilot survey and the first year regular survey are included in the LAMOST DR1. The pilot survey started in October 2011 and ended in June 2012, and the data have been released to the public as the LAMOST Pilot Data Release in August 2012. The regular survey started in September 2012, and completed its first year of operation in June 2013. The LAMOST DR1 includes a total of 1202 plates containing 2 955 336 spectra, of which 1 790 879 spectra have observed signalto-noise ratio（SNR） ≥ 10. All data with SNR ≥ 2 are formally released as LAMOST DR1 under the LAMOST data policy. This data release contains a total of 2 204 696 spectra, of which 1 944 329 are stellar spectra, 12 082 are galaxy spectra and 5017 are quasars. The DR1 not only includes spectra, but also three stellar catalogs with measured parameters： late A,FGK-type stars with high quality spectra（1 061 918 entries）, A-type stars（100 073 entries）, and M-type stars（121 522 entries）. This paper introduces the survey design, the observational and instrumental limitations, data reduction and analysis, and some caveats. A description of the FITS structure of spectral files and parameter catalogs is also provided.
