Abstract Objective To evaluate the efficacy of FOLFOX4 regimen systemic chemotherapy in treating advanced hepatocellular carcinoma (HCC). Methods The clinical data of 22 cases of advanced HCC were treated by FOLFOX4 regimen systemic chemotherapy between July 2007 and July 2013 in the First Affiliated Hospital of Sun Yat-sen University were analyzed retrospectively. The chemotherapy was given each two weeks??with a maximum of 8 cycles. The therapeutic responses were evaluated each 3 cycles and end of treatment. Results A total of 85 cycles were administered in 22 cases??with a mean of ??3.7±2.0?? cycles /case. There were no complete response??5 partial responses??5 static diseases and 12 progressive diseases. The objective response rate was 22.7% (5/22)??and disease control rate was 45.4% (10/22)??with a one-year survival rate of 12.1% and median survival time of 5.8 months in the follow up of 2-34 ??8.5±1.9??months . In 10 cases of disease control after chemotherapy??the median survival time reached up to 9.5 months. Conclusion FOLFOX4 regimen systemic chemotherapy is effective in part of advanced HCC??and represented as an effective modality.

??Abstract?? Objective To study balloon dilatation with cryotherapy under bronchoscope for subglottic stenosis in infants and young children??and to explore the efficacy of this new technology??the timing of treatment and safety. MethodFrom July 2009 to May 2014 in 28 SGS cases aged from 1 month to 3 years?? bronchoscopic balloon dilatation treatment with CO2 cryotherapy was performed?? and different types of SGS treated by minimal invasi were assessed regarding efficacy, complications and outcome. Results The infant SGS were divided into ??°~??° by severity?? and soft membrane SGS and scarring SGS by the causes of stenosis. ??° SGS included 16 cases, in which 8 cases soft membrane SGS were treated by balloon dilatation effectively?? 9 cases after combined treatment; in scarring SGS balloon dilatation was effective in 1 case?? 4 cases after combined therapy; ??° SGS included 8 cases?? soft membrane SGS were treated effectively in 2 cases?? 4 cases after combined treatment; in scarring SGS balloon dilatation was effective in 1 case?? 2 cases after combined therapy; ?? °SGS included 4 cases?? 1 case of soft membrane SGS and 1 case of scarring SGS responded well to integrated treatment .Conclusion MSCT and bronchoscopy assessment is used in grading the extent and causes of stratification in infants with subglottic stenosis?? and then we can select the appropriate treatment programs to improve the prognosis of the disease and improve life quality of SGS children.

??Abstract??The purpose of the present study was to show the different choices of periodontal surgeries in resolving various clinical problems. There were both demands of restoration in bilateral posterior areas of the patient??but their remaining of local dental tissue was different. In order to immediately restore the function and esthetic of the patient's dentition??the crown-lengthening surgery was applied on the side of more dental tissue available??the tooth was extracted on the other side of less dental tissue available and cureless apical lesion??also??implant surgery was applied electively. Soft and hard tissue augmentation was finished in implantation synchronously. The effect of final restorations was good and the patient was satisfied. The periodontal surgery played the key role in multidisciplinary treatment??therefore??its indications should be carefully and comprehensively chosen in overall treatment design.     

CXCL12/CXCR4信号通路与缺血性脑卒中新进展

缺血性脑卒中是一种严重威胁人类健康和生命的疾病,致残率和致死率较高。缺血性脑卒中会导致中枢神经系统损伤和功能障碍。缺血性脑卒中发生后,内皮祖细胞参与修复血管内皮和神经损伤,在这一过程中CXCL12/CXCR4 信号通路起着重要的作用。本文将对CXCL12/CXCR4 信号通路与缺血性脑卒中新进展进行综述。     

儿童反复呼吸道感染合理用药

反复呼吸道感染是儿童常见的临床现象,病情反复发作,影响了儿童的生长发育。由于反复呼吸道感染病因繁杂,儿科医生对本组疾病认识不足,治疗上也常存在一些误区。早期识别导致儿童反复呼吸道感染的潜在病因是正确治疗的前提,同时儿科医生也应合理用药,正确管理本病患儿。     

多重PCR检测方法在儿童流感样病例病原检测中的临床价值（附94例报告）

目的　探讨多重聚合酶链反应（PCR）检测方法在儿童流感样病例病原检测中的临床应用价值,了解儿童流感样病例病原情况。方法　收集2018年11月至2019年2月北京地区94例儿童流感样病例咽拭子标本,采用多重PCR核酸检测技术测定甲型流感病毒（InfA）、 甲型流感病毒H1N1（InfA-H1N1）、 甲型流感病毒H3N2（InfA-H3N2）、 乙型流感病毒（InfB）、 人副流感病毒、 呼吸道合胞病毒（RSV）、 人腺病毒（HADV）、 人鼻病毒（HRV）、 人博卡病毒、 人偏肺病毒（HMPV）、 人冠状病毒（HCoV）和肺炎支原体（MP）、 衣原体13种病原核酸。结果　94例标本中78例（82.98%）可测出病原,其中69例（73.40%）检出1种病原,9例（9.57%）检出2种病原; 94例标本中52例（55.32%）检出流感病原,26例（27.66%）检出非流感病原。单一病原检出由多到少为InfA-H1N1 31例,InfA-H3N2 10例,RSV 9例,HMPV 7例,InfA、 HRV、 HADV各3例,InfB、 HCoV及MP各1例。9例检出2种病原的标本中,6例检出流感分别合并其他病毒（HRV、 HADV、 RSV、 HCoV、 HMPV）,1例检出甲流H1N1和H3N2,2例分别检出RSV、 HRV及HCoV、 HADV。结论　非流感病原微生物引起流感样病例并不少见,多重PCR检测有助于全面了解流感样病例的病原和混合感染情况。
