A new type of piezoelectric oscillation-based non-contact spotting mode has been developed to overcome the disadvantages of traditional non-contact spotting modes including complicated operation procedure, cleaning difficulty of spotting needle, large sample consumption of electromagnetic microvalve and high spotting cost of piezoelectric inkjet based non-contact spotting mode. In the device, the capillary spotting needle and the piezoelectric driving device are two independent units used for replacing and cleaning capillary spotting needle. The glass capillary spotting needle is prepared by the laser melting method with adjustable diameter and low cost. The sample spotting volume of the device can be easily adjusted in the range of 10Symbolm_10-10Symbolm_9 by changing the amplitude and frequency of piezoelectric ceramic. A microarray spotting system is developed by the combination of the piezoelectric oscillation-based non-contact spotting mode and three dimensional precision displacement control technology. The multiple parameters of as-prepared microarray spotting system have been tested including spotting volume, density of spot and spotting precision. The experimental results indicate that the minimum volume of single spot with 320 pL and the highest density of spot with 4000 spots/cm2 can be achieved by the as-prepared microarray spotting system. Furthermore, the as-prepared microarray spotting system can also be employed to fabricate patterned interface.

Objective:To compare the clinical effects of direct anterior approach (DAA) and posterolateral piriformis-sparing approach (Mis-PLA) for minimally invasive surgery of total hip arthroplasty.Methods: The patients who had total hip arthroplasty from March 2015 to February 2016 were randomly divided into 2 groups: DAA group and Mis-PLA group.In the study,43 patients (45 hips) were performed with total hip replacement via the direct anterior approach (DAA group).As comparison,39 patients (42 hips) were performed with total hip replacement via the posterolateral piriformis-sparing approach (Mis-PLAgroup) at the same period.DAA group:27 male patients (27 hips),and 16 female patients (18 hips),with an average age of (57.4±7.3) years,preoperative Harris score (41.4±8.7),body mass index(BMI)(24.3±2.2) kg/m2;Mis-PLA group: 25 male patients (26 hips),14 female patients (16 hips),with an average age of (59.2±7.3) years,preoperative Harris score (39.6±8.4),BMI (24.7±2.5) kg/m2.The length of incision,operation time,blood loss,postoperative Harris score were observed and specially the hip functional recovery was fully assessed.Results: (1) All the incisions healed by first intention.No complications were found in both groups.The length of incision:DAA group:(9.2±0.7) cm and Mis-PLA group:(9.5±0.6) cm.No statistical significant differences were found (P=0.053).The operation time:DAA group (74.3±10.1) min and Mis-PLA group(37.5±4.3) min,which showed statistically significant differences(P<0.01).Blood loss:DAA group(229.6±79.2) mL and Mis-PLA group (215.7±56.0) mL.Nostatistical significant differences were found (P=0.366).(2) The patients in both groups were followed up for 6-12 months.The Harris hip scores for 6 weeks' follow-up:(85.5±4.1) in DAA group and (79.0±4.4) in Mis-PLA group,which indicated statistically significant differences (P<0.01).The Harris scores for the 6-month follow-up:(94.3±2.7) in DAA group and (95.2±1.9) in Mis-PLA group.No statistically significant differences were found (P=0.125).The basic daily hip function analysis for the 6-week follow-up:walking speed: no statistically significant differences were found between the two groups(P=0.298);Climbing stairs: Mis-PLA group' outcome was better than DAA group's with statistical differences (P=0.047);Circling,sitting and wearing shoes and socks: outcomes in DAA group exceeded Mis-PLA group's with statistically significant differences (P<0.01,P=0.016,P<0.01).Conclusion: Total hip arthroplasty through either DAA or Mis-PLA approaches could result in very satisfactory clinical effect.Comparing with DAA,Mis-PLA requires less operation time,shorter learning curve,which indicates that it is a re-latively safer approach.The advantages of total hip arthroplasty through direct anterior approach lie in less positional limitation in the early stage of postoperative period,as well as a faster recovery of hip function.
