Objective To investigate the clinical effect of implantable collamer lens ( ICL) in the treatment of super high myopia. Methods 20 patients with high myopia were given ICL,and changes in patients with visual acuity,intraocular pressure and corneal endothe-lial cells,and surgery-related complications and outcome were observed. Results Before surgery,the visual acuity of patients was (0. 10±0. 05),and postoperative (0. 60±0. 20),the difference was statistical significance(P<0. 05);the intraocular pressure and corneal endothe-lial cells of patients did not change significantly after surgery,with less postoperative complications. Conclusion The ICL has a very signifi-cant effect in the treatment of super high myopia,which can help to improve the patient's quality of life,and it is worthy of wide promotion and application.

The clinical application of POCT technology is growing wider,the most significant advantage of this technology is to get the test results quickly,Therefore clinicians could make clinical decisions in time and choose appropriate approaches or interventions.However,it should be taken seriously that while POCT helps patients to get medical care successfully,the potential harm to the patients cannot be ignored.Hence it is essential that normative documents should be imposed as soon as possible.The technology of POCT can benefit the entire society only if the proper administration to approve the use of POCT technology is taken control of; the comprehensive and normative quality management is implemented,and the appropriate training to the related clinicians and nurses is enforced.

This paper analyzes social background and ethical problems of disposing and using unreasonably High-tech equipment, and puts forward relative proposals of contermeasure.

Objective To investigate the value of 3D rapid prototype technology in therapy of complex pilon fractures.Methods In this study,60 patients with pilon fracture who had been hospitalized during January 2013 to May 2014 were randomly and equally divided into a 3D group and a control group according to their hospitalization order.The 3D group:21 males and 9 females,an average age of 34.8 ±6.0 years,13 cases of AO type C2 and 17 ones of AO type C3.The control group:21 males and 9 females,an average age of 35.8 ±6.2 years,12 cases of AO type C2 and 18 ones of AO type C3.The 3D group received surgery aided by rapid prototype and 3D printing while the control group underwent conventional surgery with open reduction and internal fixation.In the 3D group,the distal tibia models were manufactured by 3D rapid prototyping technology based on the 3D reconstructions which were accomplished by computer aided technology.The diagnosis,classification and preoperative plan were then conducted using the models.The 2 groups were compared in terms of operation time,postoperative skin necrosis and infection,and Maryland foot function scoring at the last follow-up.The 2 groups were compatible in preoperative demographic data (P ＞ 0.05).Results There were significant differences between the 3D and control groups in operation time (65.1 ±4.8 minutes versus 80.5 ± 3.6 minutes) and rate of postoperative complications [6.7％ (2/30) versus 16.7％ (5/30)] (P ＜0.05).There was no significant difference between the 2 groups in the excellent to good rate by Maryland foot function scoring at the last follow-up [76.7％ (23/30) versus 73.3％ (22/30)] (P ＞ 0.05).Conclusion Since rapid prototype and 3D printing technology can display the morphology of pilon fracture intuitively and stereoscopically,it helps surgeons with accurate assessment of the fracture.3D printed models of the pilon fracture pre-operatively raise the accuracy of reduction,reduce both operation time and incision complications,and facilitate functional recovery.

Health problems caused by age-related hearing loss can not be ignored, and elderly hearing screening that aimed to detect early and intervene early is of importance. As one of the main screening tools, elderly hearing screening scales are rarely used in China, so the paper mainly reviewed the development and application of hearing screening scales for elderly and provided a reference for future research and clinical application.

The occurence and progress of hepatocellular carcinoma(HCC)is a complex network inter-action process connected by multiple signaling pathways involving genes,cells and various active molecules. The effects and functions of biological molecular markers also vary among different pathways. Moreover,wheth-er the molecular markers have prediction effects for the prognosis of HCC remains unclear,and studies investing this issue are still insufficient. The current studies reveal that molecular markers involves in multiple pathways including gene expression,gene regulation,cell cycle regulation,cancer stem cell proliferation and differentia-tion. These processes are intimately associated with the occurrence and prognosis of HCC. The relevant gene or molecular that may indicate the prognosis of HCC includes p53 gene,long non-coding RNA,cell cycle regula-tors,liver cancer stem cell surface-associated molecules,etc.

Hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT) is one of the difficult points of liver cancer treatment.At present,there are various clinical treatments of HCC with PVTT which have great significance to lengthen the survival time of patients with liver cancer and improve the quality of life.Surgical therapy and interventional treatment play important roles in the treatments of HCC with PVTT.

Objective To investigate the effect of early goal lactate clearance rate therapy in patients with severe sepsis or septic shock.Methods Articles were retrieved from PubMed,Embase,Cochrane Library,Wanfang and CNKI before March 5,2016.Inclusion criteria included the subjects concerning patients with severe sepsis or septic shock reported as randomized controlled trial (RCT),which endpoints were the mortality,the length of ICU stay and hospital stay.RevMan 5.3 software was used for Meta analysis.Results There were 5 RCTs meeting inclusive criteria including 860 patients.It was shown by Meta analysis that early goal lactate clearance rate therapy was associated with decrease in the 28-day mortality(RR =0.73,95％ CI:0.60-0.88,P ＜ 0.01),shorten the length of ICU stay (WMD =-2.41,95％ CI:-4.68--0.14,P ＜ 0.05),but not associated with decrease of the length of hospital stay(WMD =-0.13,95 ％ CI:-4.58-4.31,P =0.95).Conclusion Early goal lactate clearance rate therapy was associated with significant improvement in 28-day mortality and the length of ICU stay but not with the length of hospital stay in patients with severe sepsis or septic shock.
