Objective To investigate the effects of MK-801 on the rat F-VEPs during the critical period of visual plasticity.Methods We performed the F-VEPs examination in the normal Long Evans rats and the MK-801 treated rats on their postnatal days 14 and 28.Results After eye-opening,the latency of F-VEP main wave became shorter(P

0.05). The screening tests for LA is simple and reproducible and it may be useful in clinical study of SLE.

Laboratory study is an important part of medical research.In the past few years,many significant biosafety incidents occurred in the medical field in and out of China.We here try to analyse the problem of biosafety management of laboratories,stating the importance of biosafety management in laboratory,and put forward countermeasures.

To observe the high glucose concentration on proliferation and fibronectin (FN) synthesis of glomerular mesangial cells (GMC),a culture of human GMC was established and the cell proliferation was assessed using MTT method and cell counting, and the changes in FN was analyzed with RT PCR and ELISA. It was found that high glucose concentration inhibited GMC proliferation and increased FN synthesis in dose and time dependent manner.The results suggest that hyperglycemia may have important role in the development of diabetic nephropathy.

Objective To investigate the effect of infecting betamethasone dipropionate 5mg/betamethasone disodium hydrogen phosphate 2mg in articular genu cavity on osteoarthritis.Methods 100 patients were randomly divided into two groups, the treatment group and the control group. The treatment group was treated with diprospan,injected into the inside of knuckle. The control group was treated with oral administration NSAIDs. Results In treatment group the rate of amelioration was 84% after one injection,the rate of amelioration was 90% after one course of treatment. Conclusion Injected diprospan into the inside of knuckle could relieve pain of arthritides, improve the function of arthrosis.

Objective To observe the clinical short-and long-term curative effect of the surgical treatment of female stress urinary incontinence (SUI) with tension-free vaginal tape-obturator (TVT-O) treatment,and discuss the safety of the operation and postoperative quality of life.Methods The data were collected from 130 patients with SUI who were underwent TVT-O treatment.The patients'perioperative period,follow-up of postoperative complications,and comparison of the quality of life before and after surgery were analyzed retrospectively.Results A total of 130 patients was successfully completed their surgeries with a mean operative time (47.01 ± 18.82)min,average blood loss (64.38 ±99.62)ml,mean catheterization (2.67 ±0.90)d,and the average length of stay (4.73 ±2.14)d.A total of 101 cases was completed the postoperative follow-up with (a) preoperative quality of life in patients with ⅡQ-7 score 6 to 21 points and an average of (15.74 ± 3.87) min,(b) symptoms of lower urinary tract UDI-6 score of 3 to 22 minutes and the average (10.51 ± 3.70) min,(c) postoperative quality of life improved significantly ⅡQ-7 score from 0 to 21 points and an average of (1.59 ±4.37)points,and (e) UDI-6 score 0 to 14 points and an average of (1.63 ± 2.66)points.A total of 73 patients (72.3％) had the postoperative urinary incontinence,which subjective symptom were completely cured,significant improvement was 11 cases (10.9％),ineffectiveness was 6 cases (5.9％),pad using was 13 patients (12.9％),vaginal mesh exposure and erosion was 2 patients(2.0％),the sexual life postoperatively was affected in 8 patients (7.9％).Conclusions TVT-O treatment of SUI is not only easy to operate but also has clinically high security,few complications,low recurrence rate,and significantly improved patients' living quantities.However,patch compli cations can not be ignored and need further discussion.

Objective By the designing and clinical application of score table and focus nursing sheet to brain trauma patients,paramedics can observe state of illness individually,optimize the nursing care in a further performance,and ensure the security of brain trauma patients more profitably.Methods To design the score table and focus nursing sheet according to the disease species and symptoms,contrast to the previous nurse observing table in noting time,error rate,exam results and surgeon satisfaction degree.Results By evaluating 130 cases in this test,the score table and focus nursing sheet were superior to the previous nurse observing table.Conclusions With the score table and focus nursing sheet,nurses can observe the illness and note the progress more scientifically and conveniently,the concept of individuation and specialization are worthy of recommending.

OBJECTIVE: To search the features and the treatment of vascular compressive syndrome caused by the facial, acoustic nerves. METHOD: Ten cases of vascular compressive syndrome caused by the facial, acoustic nerves were included in the group,which were treated by microvascular decompression(MVD). Besides, the microanatomic relationship between the nerve and their adjacent vessel at the root exit zone (REZ) were observed under microscope or nasoendoscopy in MVD. RESULT: Tinnitus, vertigo and facial spasm disappeared after MVD in 7 cases (70%), improved in 2 cases (20%), and relapse in 1 case (10%). All cases were found out vessels compressing at the root zone of the facial nerve and the auditory nerve. CONCLUSION The Clinical features of vascular compressive syndrome caused by the facial, acoustic nerves are facial spasm, tinnitus, and vertigo, for which microvascular decompression has a positive therapeutic effect as long as the diagnosis is correct.

Objective To evaluate the efficacy and safety of continuous infiltration of Lidocaine in joint replacement surgery.Methods From May 2013 to October 2013,patients scheduled to undergo total hip or total knee arthroplasty were randomized into two groups:the local infiltration analgesia group received continuous infiltration of Lidocaine while the other group received PCIA filled with fentanyl after surgery.The equipments were removed 48 hours after the surgery.The visual analogue scale score at five points (immediate postoperative,24 hours after the surgery while resting,24 hours after the surgery while exercising,48 hours after the surgery while resting,48 hours after the surgery while exercising) were recorded and if the score was higher than 4,analgesics wound be given to the patients.The vital sign,blood test,ECG,the circumference of lower limbs,the range of motion of the joint,the rehabilitation and complications were also recorded.Results 42 patients were included,11 male and 31 female.There were 25 patients and 36 total knee arthroplasties.17 patients underwent a total of 19 hip arthroplasties.The demographic data,the diagnosis and the surgery type were comparable between two groups.The VAS scores at immediate postoperative,24 hours and 48 hours after the surgery while resting,the average dose of analgesics and the complication rate were statistically different be tween two groups.However,the VAS scores at 24 hours after the surgery and 48 hours after the surgery while exercising,the change of the circumferences of the lower limb,the range of motion of the joint,the rehabilitation satisfactory rate and length of stay were comparable between two groups,while no significant difference was observed.One patient in the PCIA group suffered from incision fat liquefaction and healed after three weeks.There were no infection and subcutaneous hydrocele in both groups.Conclusion Continuous infiltration of Lidocaine is more effective than the PCIA while resting after joint replacement surgery and no inferior to it while exercising.It can decrease the amount of Opioid.
