Objective To compare the curative effects of extraperitoneal laparoscopic hernia repair and tradi-tional hernia repair in the treatment of inguinal hernia.Methods The clinical data of 200 inguinal hernia patients in our hospital from October 2013 to Novermber 2015 were retrospectively analyzed.They were divided into traditional hernia repair group (100 cases)and laparoscopic hernia repair group (100 cases)according to different surgical treatment.The operation time,bed activity time and hospital stay of the two groups were detected.The uroschesis, hydrocele,incidence of postoperative pain and recurrence rate of the two groups were detected.Results The opera-tion time between the two groups had no significant difference(t =1.74,P >0.05).The bed activity time[(2.6 ± 1.6)h]and hospital stay[(5.7 ±2.1 )d]of the laparoscopic hernia repair group were better than the traditional hernia repair group[(9.1 ±3.3)h,(7.4 ±2.3)d,t =17.72,5.46,all P <0.05].The uroschesis 3.0%,hydrocele 0,incidence of postoperative pain 10.0% and recurrence rate 0 of the laparoscopic hernia repair group were lower than the traditional hernia repair group(21.0%,15.0%,50.0%,12.0%,χ2 =15.17,15.34,39.11,11.69,all P <0.05).Conclusion The recovery is fast in inguinal hernia patients treatment by extraperitoneal laparoscopic hernia repair,complication is little,which is worthy of application.

A total of 256 medical professionals at the hospitals of different levels were interviewed and requested to complete the relevant questionnaires.The findings revealed that the top five unsatisfied items were growth & development,working conditions,doctor-patient relationship,income and social status.The levels of job satisfaction varied with their specific occupations and technical titles.Around two thirds of them once had the thought of leaving their pre-hospital care posts.

Objective To evaluate the perioperative nursing of transurethral bipolar plasmakinetic resection of prostate(TUPKRP).Methods One hundred and thirty BPH patients underwent transurethral prostatectomy with the bipolar plasmakinetic technique.All patients received preoperative mental nursing,holistic nursing care and health education before operation.Results All patients passed through the surgery and were given nursing intervention.They were discharged after rehabilitation.Conclusions TUPKRP is an important miro-invasion operation for treatment of BPH.The important points are preoperative mental nursing,rational use of drug,postoperative bladder irrigation and prevention of hemorrhage.

Objective To explore the DSA mainfestations of MoyaMoya disease.Methods 19 patients, underwent CT before DSA, showed intracranial hemorrhage. All patients were then examined by angiography via femoral artery approach. Results All cases were diagnosed as MoyaMoya disease through DSA. The findings of DSA showed characteristic manifestations as the following: 1. Stenosis or occlusion of the invoved arteries. 2. Smoke like capillary vascular network spreading from supraseller cistern to cerebral base. 3. Development of collateral circulation. Conclusions DSA is the main method for the diagnosis of MoyaMoya disease, CT can only localize the site of cerebral hemorrhage.

Objective To discuss the application effects of CBI teaching method in medical English Teaching of respiration medicine. Methods Dividing 120 students of Grade 2009 in Jining Medical College into two groups including control group (60) and experimental group (60). The tradi-tional teaching method was adopted in the control group and CBI teaching method was adopted in the experimental group. After finishing the courses, medical professional English level test and standard-ized patients test were applied in the two groups. Students' English studying interests and autonomous English learning ability were also investigated by questionnalres. SPSS 17.0 software was used for sta-tistical analysis, and the data were processed by t test and 字2 test, with the level of a test equal to 0.05. Results The medical professional English level test scores, standardized patients test scores and the total average scores of autonomous English learning ability in experimental group were respectively [(81.97±4.91), (80.33±5.85), (3.88±0.38)], and they were significantly higher than those in the control group [(70.40±4.78), (70.48± 4.79), (2.98±0.26), with P values below 0.01]. Satisfaction degrees in the improvement of learning motivation, learning time, learning method, learning attitude and dealing with study difficulties in experimental group were better than those of control group (χ2=13.084, 8.000, 13.297, 11.627, 13.374, P=0.000). Conclusion CBI teaching method is better than traditional teaching method and it transfers English learning into the learning of professional knowledge and skills of respiratory medicine, stirs the interests of students, improves their autonomous English learning ability and strengthens their abilities to learn and apply English language.

Objective To investigate the clinical effects of the posterior atlantoaxial pedicle screw fixation combined with unilateral axial spinous process and lamina screws and allogeneic bone graft for atlantoaxial instability.Methods From March 2010 to April 2014,data of 10 patients with atlantoaxial instability who had undergone atlanto-axial vertebral pedicle fixation and interbody fusion combined with posterior atlanto-axial spines lamina nails were retrospectively analyzed.There were 6 males and 4 females with an average age of 39 (range,16-62) years old.The inclusion criteria was atlantoaxial instability together with unilateral vertebral artery segment high cross deformity (7 patients) or atlantoaxial joint break bad involving unilateral pedicle (7 patients).3 patients have spinal cord disease symptoms and physical signs,both suffered limited neck mobility and pain.The VAS scores were 1-8,with an average of 3.70±2.11.Preoperative X-ray,CT three-dimensional reconstruction and MRI were collected.X-ray and CT examination were performed 7 d and 1,3,6,12 months after operation to evaluate the internal fixation and bone grafting fusion.Results There's no occurrence of cervical spinal cord and vertebral artery injury.Screws were successfully implanted.1 case's incision occurred infiltration liquid 3 days after operation.For allograft rejection consideration,we changed the plan,and the infiltrating stopped 5 days later.Other incisions were all primary healing.VAS scores were 1.01±0.89 after operation,which was significantly reduced.X-ray showed good recovery of cervical sequence after the operation,and CT revealed 1 patient with atlas pedicle screw in the medial cortex damage.Spinal canal was without infringing,and the other screw positions were normal.6 months after operation,X-ray or CT examination both showed bony fusion.Conclusion Atlantoaxial pedicle screw fixation combined with unilateral axial spinous process and lamina screws and allograft bone graft fusion for the treatment of atlantoaxial instability can observe good clinical effects.

Objective To investigate the efficient methods used for tracing endothelial progenitor cells(EPCs)after transplantation in injured lung tissue.Methods Thirty clean grade healthy syngeneic SD female rats were divided into three experimental groups(n =10):(1)sham group,rats treated with intravenous phosphate-buffered saline(PBS)instead of lipopolysaccharide(LPS)followed by EPCs graft;(2)PBS-treated group,rats treated with intravenous PBS after intravenous injection of LPS to produce acute lung injury;(3)EPC-treated group,rats treated with EPCs after intravenous injection of LPS to produce acute lung injury.The transplanted EPCs were got from the same genetic species of the SD male rats.Rats of each group were sacrificed 7 days after EPCs transplantation.Their whole lung tissues were harvested to detect the expression of Y-chromosome by using hybridization in situ and RT-PCR assay.Statistic package of SPSS16.0 was used for the data analysis and significant differences between means were evaluated by ANOVA analysis.Results Compared with the other two groups,positive signals of sex-determining region y were found in lung endothelium from the EPC-treated group.Conclusions Y chromosme specific probe can be one of efficient methods for tracing stem cells after transplantation.
