In surgery operations, wound should be cleaned with warm sterilized saline solution. In order to reach rapidly warming the washing solution from the room temperature during the surgery, we designed a thermostatic medical infusion pump. The present paper mainly presents researches on the two temperature control methods in the standby mode and in the flushing mode of the system. In the standby mode, the traditional proportional-integral-derivative (PID) control algorithm was adopted. In the flushing mode, dynamic characteristics of the system was changed in real time, which made the thermostatic control process more complex, and the fitted control function combined with the PID control algorithm was adopted in this mode. The temperature control parameters were adjusted in real time according to the initial temperature and the flow rate of the washing solution to obtain a constant temperature of the washing solution, no matter how the initial temperature and the flow rate are changed. The experiment results showed that this kind of control system performed well with a high accuracy.

This study was aimed to investigate effect of aconite alkaloids on proliferation and apoptosis of hu-man gastric cancer cell line SGC-7901 . Effects of different concentrations of aconite alkaloids on proliferation of human gastric cancer cell line SGC-7901 were investigated with MTT assay; induced apoptosis and cell cy-cle blocking were detected with flow cytometer ( FCM ) . The results showed that the IC50 of aconite alkaloids on human gastric cancer cell line SGC-7901 was 0 . 2318 ± 0 . 0022 , 0 . 1601 ± 0 . 0227 , 0 . 1031 ± 0 . 0231 mg/ml at 24 h , 48 h and 72 h , respectively , compared to the control group with significant difference ( P <0.01). When the aconite alkaloids concentration was 0.8 mg/ml, it appeared with obvious apoptosis. The apop-tosis rate was ( 59 . 38 ± 5 . 05 )%. The FCM detection showed that compared with control group , the percentage of S-phase cells increased in the treatment group . And a typical sub-diploid peak appeared before G0 / G1 phase . It was concluded that aconite alkaloids can inhibit the proliferation of human gastric cancer cell line SGC-7901 in vitro, induce the apoptosis of cells and make SGC-7901 cells remain in S phase.

Objective:To investigate the roles of donor alveolar maerophages and the recipient circulating neutrophils in early-stage reperfusion injury of lung allograft,and to study the interaction between the 2 kinds of cells.Methods:Twenty pairs of size-and weight-matched adult mongrel dogs were randomly assigned to 4 groups:C(control),D(leukocyte-depleted blood reperfusion),M(maerophage inhibition)and DM(leukocyte-depleted plus macropbage inhibition).The 20 cases of left lung transplantations were performed by the same surgeon.All procedures were identical,except that the donors in Group M and DM received the macrophage inhibitor gadolinium chloride(14 mg/kg)intravenously 24 h before operation,and that the recipients in Group D and DM underwent initial 10 min reperfusion with leukocyte-depleted blood collected from donors'inferior vena cava. All lung allografts were reperfused for 2 h.Results:Compared with Group D and C,macrophage inhibition ameliorated PO_2/FiO_2 and mean pulmonary arterial pressure(mPAP)consistently after 30 min reperfusion in Group M and DM;the parameters of lung reperfusion injury(malonaldehyde activity,wet/dry ratio)at 120 min after reperfusion were also significantly improved(P

Objective To compare the advantages and disadvantages of uniportal video-assisted thoracic surgery(uniportal-VATS)and three portal VATS in treatment of benign pulmonary diseases. Methods The clinical data of 66 patients with benign pulmonary disease treated by VAST from June 2015 to October 2016 were retrospec-tively analyzed. The patients were divided into two groups according to the specific operation. There were 32 patients (18 males and 14 females)in uniportal-VATS group. There were 34 patients(18 males and 16 females)in three portal VATS group. The operative time ,intraoperative blood loss ,thoracic drainage volume at 24 h after opera-tion,incision length,and the time of postoperative drainage of thoracic cavity,postoperative third day pain score and complication rate were compared between the two groups. Results The patients in the experimental and the control groups were successfully operated according to the scheduled protocol. No thoracotomy was performed. There was no statistical difference in the volume of blood loss,the volume of pleural drainage after 24 hours,the time of postoperative drainage of thoracic cavity ,the length of hospital stays and postoperative complications in uni-portal-VATS group and three portal VATS group(P>0.05). The pain score and postoperative third day pain score of the uniportal-VATS group was better than that of the three portal VATS group(P<0.05),but the operation time of the uniportal-VATS group was longer than that of the three portal VATS group(P<0.05). Conclusion Uniportal-VATS is safe and feasible for the treatment of benign lung diseases. It is more minimally invasive and beautiful than traditional three-hole thoracoscopic surgery. It is worthy of promotion and has broad prospects.

Background Selective laser trabeculoplasty (SLT) is a safe and effective therapy to the treatment of primary open angle glaucoma (POAG),and the clinical application is approved by American FDA.However,the relevant researching outcomes from several single-center study are in dispute owing to non-uniform approach in China.A muhicenter clinical trial is need to verify the effectiveness of SLT for Chinese POAG.Objective This study was to investigate the safety and efficacy of SLT in Chinese POAG patients.Methods A prospective,multicenter and self-controlled clinical trail was designed.Sixty-two eyes of 62 POAG patients with the age of ≥ 18 years were enrolled.Frequency SLT was performed around 360° angle using Lumenis Selecta DuetTM or Lumenis Selecta Ⅱ laser instrument,with the 100 non-overlapping spots,3 ns preset time,400 μm size of laser spot and 0.6 mJ energy.The operated eyes were followed-up for 6 months.The curative effects were checked including intraocular pressure (IOP),IOP-lowing value,number and percentage of IOP-lowing 20％ and 30％.The therapyrelated complications were recorded including the number of conjunctival congestion and cloudy of the anterior chamber.Results The preoperative IOP was (25.7±2.6) mmHg in the 62 eyes.The IOP was significantly lowed 1 day,2 weeks,4 weeks,3 months and 6 months after SLT in comparison with preoperative IOP (all at P＜0.001) with the lowest value of (16.5±4.5)mmHg in postoperative day 1.IOP was stable from 4 weeks to 6 months after operation.The mean lowing-value of IOP was 5.3-9.2 mmHg from 1 day through 6 months after SLT.The percentage of eyes 20％ drop in lOP was 83.9％,and that of 30％ drop was 58.1％ in postoperative day 1.In 6 months after SLT,percentages of eyes 20％ and 30％ drop in IOP were 56.5％ and 27.4％,respectively.Conclusions SLT is a safe and effective method of lowing IOP for POAG eyes in Chinese population.

Objective nvestigate the propofol combined with fentanyl anesthesia in orthopedic manual reduction applications.MethodsAugust 2015 to December 2016 in our hospital treated 120 cases of acute long bone closed fracture and ankle, shoulder dislocation and other patients, efficient analysis anesthesia, surgery time, patient recovery time, propofol is added volume and total volume, and detection 3min, 1min, 3min, 5min and waking SpO2, HR, MAP, RR values.Two groups of patients after treatment, were given nursing intervention, such as routine diet guidance, nutrition support, health education.after administration before it is administered.Resultsanesthetic effect experimental group total efficiency is higher, the difference was statistically significant (P<0.05);after simultaneous administration of all patients 1min, 3min, 5min signs were lower than prodrug 3min signs, the difference statistically significant (P<0.05), after clear signs of its former administration 3min with no significant difference;experimental group recovery time, propofol bolus of propofol than with total control were lower, the difference was statistically significant (P<0.05);and the two groups were similar to the operation time, the difference was not statistically significant.ConclusionIn summary, propofol combined with fentanyl anesthesia for patients to take the treatment of orthopedic manual reduction obviously worthy of clinical use.
