在贵州省六盘水市杨梅乡慕尼克村,利用陷阱法捕捉到3号麝鼩属(Crocidura)标本。本次采集标本的体形较小,头体长(49.0±0.8)mm,尾长[(41.8±4.2)mm]略短于头体长(尾长/头体长为85%)。背毛呈浅灰褐色,腹毛颜色浅于背毛,呈灰色。尾部双色,背侧黑褐色,腹侧淡于背侧。前足背部白色,后足则为淡灰色。尾近乎裸露,尾基约1/3着生稀疏白色长毛。颅全长(15.92±0.55)mm,脑颅高(4.75±0.18)mm。上门齿1枚,有一长而大的前尖和一小而矮的后尖。上单尖齿3枚,第1单尖齿最大,第2单尖齿略大于第3单尖齿,1枚第四前臼齿(P4),3枚臼齿。上述特征与东阳江麝鼩(***)模式标本的描述和鉴定特征基本一致,因此将3号采集标本鉴定为东阳江麝鼩。基于Cyt b基因进行分子系统发育分析,采集标本与麝鼩属物种中的东阳江麝鼩遗传距离最近,在0.004~0.027之间。系统发生树显示,3号标本与东阳江麝鼩构成一个单系进化分支,进一步证实本次采集的3号标本是东阳江麝鼩,为贵州省分布新记录种。

地下浅层气的存在会对地铁项目的勘察、施工以及后期正常运营构成安全隐患。采用基于地质统计学和可靠性分析的概率方法,对杭州某地铁站场地的电阻率静力触探测试数据进行分析。通过回归分析移除电阻率数据的趋势项,以变差函数为工具,描述电阻率残差在竖向和水平向上的各向异性,采用克里格插值对未采样点参数值进行最优线性无偏估计,采用一阶可靠度方法获取基于电阻率的地下浅层气分布三维概率图。分析表明:电阻率残差具有显著的各向异性,在竖直和水平方向的自相关距离分别为5.1 m和55.6 m。在考虑不同土体电阻率背景值不同的前提下,采用一阶可靠度方法建立了浅层气三维概率分布图。该场地竖直方向上浅层气分布于25m附近及30~35m深度区间内,水平方向上则集中分布于RCPTU1点位附近。可基于该结果提出针对性的防治对策,为布设排气孔、浅层气监测等治理措施提供依据。

BACKGROUND: Liver transplantation has evolved as a successful treatment for patients with end-stage liver cirrhosis and acute liver failure. Postoperative survival rates have increased to 90% in I year and 80% in 5 years as a result of improvements in immunosuppresion, perioperative management and surgical techniques. However, a wide range of postoperative complications are of technical or medical origin. This study was undertaken to determine the relationship between the technical improvements and optimal timing of surgery and its outcome. METHODS: From April 1999 to October 2005, typical orthotopic or piggyback liver transplantation was performed in 70 patients (58 men and 12 women, aged 19-74 years). Twenty-four patients had liver carcinoma and cirrhosis, and 46 had benign liver disease. RESULTS: All patients survived the operation and 14 died in the first month after surgery because of respiratory failure (6), respiratory failure accompanied by acute renal failure (4), intra-abdominal hemorrhage and infection (2), and cerebral edema (2). A total of 76 complications occurred in the 70 patients after operation: pneumonia (34), right pleural effusion (11), bile leakage (7), postoperative intra-abdominal hemorrhage and infection (4), acute renal failure (4), acute rejection (3), wound infection (2), biliary tract stenosis (2), severe cholangitis derived from cholelith (2), morphological alteration of biliary tree (2), cerebral edema (2), empyema (1), chronic rejection (1), and wound hematoma (1). Finally, 33 patients survived more than 6 months, 16 more than I year, 4 more than 2 years, and 2 more than 6 years after operation. The perioperative survival rate was 80% in this series. CONCLUSIONS: Liver transplantation is an effective treatment for patients with end-stage liver disease. To obtain good results, improvements of surgical technique, optimal timing and better postoperative care are needed.

BACKGROUND: Fulminant hepatic failure manifests a rapid onset, serious complications, and a high mortality, but still there is a possibility of recovery. Once the patient is able to pass a crisis, the liver is able to regenerate completely and regain its normal function. Therefore it is of vital importance to determine the eligible timing for transplantation. Premature surgery might result in a loss of the chance of internal medical treatment and misuse of liver resources, whereas delayed surgery might increase the difficulty of treatment in the preoperative period and the possibility of complications and medical expense, which eventually result in decreased rate of success and survival. This problem remains worldwide how to choose the optional timing of operation. METHODS: Thirty-six patients with severe hepatitis were treated by orthotopic liver transplantation. The distribution of MELD scores in these patients was: 10-19 in 8 patients, 20-29 in 10, 30-39 in 11, and 40 in 7. They were divided into two groups: MELD score = 30. Parameters (1-year survival rate, complications, preoperative use of artificial liver, operative time, volume of bleeding and blood transfusion, and average hospital costs) were examined as prognostic factors after liver transplantation. RESULTS: The I-year survival rate of the MELD score = 30 group (77.8% and 33.3%, P=0.007), and the rate of complications in the = 30 group was higher (P=0.008). CONCLUSION: This study shows that when the MELD score is <30 it may be the optimal time to perform liver transplantation for patients with severe hepatitis.

In December 2019, a new type viral pneumonia cases occurred in Wuhan, Hubei Province;and then named "2019 novel coronavirus(2019-nCoV)" by the World Health Organization(WHO) on 12 January 2020. For it is a never been experienced respiratory disease before and with infection ability widely and quickly, it attracted the world’s attention but without treatment and control manual. For the request from frontline clinicians and public health professionals of 2019-nCoV infected pneumonia management, an evidence-based guideline urgently needs to be developed. Therefore, we drafted this guideline according to the rapid advice guidelines methodology and general rules of WHO guideline development;we also added the first-hand management data of Zhongnan Hospital of Wuhan University. This guideline includes the guideline methodology, epidemiological characteristics, disease screening and population prevention, diagnosis, treatment and control(including traditional Chinese Medicine), nosocomial infection prevention and control, and disease nursing of the 2019-nCoV. Moreover, we also provide a whole process of a successful treatment case of the severe 2019-nCoV infected pneumonia and experience and lessons of hospital rescue for 2019-nCoV infections. This rapid advice guideline is suitable for the first frontline doctors and nurses, managers of hospitals and healthcare sections, community residents, public health persons, relevant researchers, and all person who are interested in the 2019-nCoV.
