Objective To investigate curative effect of traditional open surgery and laparoscopic surgery on pediatric patients with cryptorchidism.Methods Sixty cases with cryptorchidism were randomly divided into two groups.Thirty cases in the control group were with open surgery,and 30 cases were given laparoscopic surgery and served as laparoscopic group.Operation time,blood loss,bed time,postoperative hospital stay,evaluating curative effect and complications were recorded.Results Twenty-three cases were unilateral cryptorchidism and 7 cases were bilateral cryptorchidism in laparoscopic group.The blood loss and operating time of patients with unilateral and bilateral cryptorchidism in laparoscopic group were (3.2± 0.5),(5.1 ± 1.4) ml,and (41.1 ± 6.3),(67.3 ± 5.6) min.In the control group,24 cases were with unilateral cryptorchidism,6 patients with bilateral cryptorchidism.The blood loss and operating time of patients with unilateral and bilateral cryptorchidism in control group were (13.4± 1.8) and (17.7 ± 2.1) ml,(56.1 ± 5.7) and (81.2 ± 8.9) min.The differences between groups were statistically significant (t =29.91,27.34,9.67,7.24;P＜ 0.05).The stay bed time and postoperative hospital time in observation group were (2.7±0.6),(4.3±0.9)d,significantly lower than those of the control group ((5.8 ± 0.7),(8.1 ± 0.5) d),and the differences were statistically significant(t =18.42,20.22;P＜0.05).Wound healing in two groups were better during follow-up periods,after operation,B ultrasound showed that 4 cases of poor blood supply,and located in the scrotum testis above middle,inelasti in control group,while there were without abnormal in observation grtoup with scrotal testis at bottom and elastic.The curative effect of observation group was better than that of control group (x2 =2.41,P＜0.05).Three cases of observation group occurred surgical infection.One case was scrotal testes retraction and 2 cases with atrophy,which needed a second operation.The complications occurred number of observation group was significant different from that in control groups(P＜0.05).Conclusion The laparoscopic is with small incision,good curative effect,quick recovery and less complications,and children with less pain,shorter hospitalization time,low cost than traditional open surgery treatment of children with cryptorchidism,which is worth popularizing widely used.

BACKGROUND:Spine minimaly invasive technique through foraminal mirror is the method to treat lumbar disc herniation with minimal wound. This technique can be conducted under local anesthesia, and does not need to resect the smal joint or destroy the vertebral plate, and has smal damage to the spine. OBJECTIVE: To explore the short-period effects of transforaminal endoscopic spine system for adjacent-segment degenerative changes-caused low back pain after lumbar fixation and fusion. METHODS:A total of 31 patients with degenerative changes after posterior lumbar bone graft fusion fixation, who required secondary surgery, were enroled in this study, including 23 males and 8 females, at the age of 45-81 years old. The postoperative time was 1.1-5.7 years. There were 3 cases of L3-4 single segment, 15 cases of L4-5 single segment, 8 cases of L5S1 single segment, and 5 cases of multi-segment. These patients were treated with transforaminal endoscopic spine system, and folowed up for 6 months. Visual Analogue Scale score and lumbar function Japanese Orthopedic Association score were observed. RESULTS AND CONCLUSION: Lumbar and leg pain symptoms were relieved noticeably during the operation. The patient could walk immediately after the surgery, and the postoperative recovery was quite satisfactory. Visual Analogue Scale score was lower immediately, 1, 3 and 6 months after treatment compared with pre-treatment. Lumbar function Japanese Orthopedic Association score was higher immediately, 1, 3 and 6 months after treatment compared with pre-treatment. Results verify that transforaminal endoscopic spine system for degenerative changes after posterior lumbar bone graft fusion fixation has some advantages such as high safety, short operation time, less hemorrhage, less complications, rapid restoration and easily accepted by patients.

Background: and Purpose The rate of donepezil discontinuation and the underlying reasons for discontinuation in Asian patients with Alzheimer’s disease (AD) are currently unknown. We aimed to determine the treatment discontinuation rates in AD patients who had newly been prescribed donepezil in routine clinical practice in Asia. Methods: This 1-year observational study involved 38 institutions in seven Asian countries, and it evaluated 398 participants aged 50–90 years with a diagnosis of probable AD and on newly prescribed donepezil monotherapy. The primary endpoint was the rate of donepezil discontinuation over 1 year. Secondary endpoints included the reason for discontinuation,treatment duration, changes in cognitive function over the 1-year study period, and compliance as assessed using a clinician rating scale (CRS) and visual analog scale (VAS). Results: Donepezil was discontinued in 83 (20.9%) patients, most commonly due to an adverse event (43.4%). The mean treatment duration was 103.67 days in patients who discontinued. Among patients whose cognitive function was assessed at baseline and 1 year, there were no significant changes in scores on the Mini-Mental State Examination, Montreal Cognitive Assessment, and Trail-Making Test–Black and White scores, whereas the Clinical Dementia Rating score increased significantly (p<0.001). Treatment compliance at 1 year was 96.8% (306/316) on the CRS and 92.6±14.1% (mean±standard deviation) on the VAS. Conclusions In patients on newly prescribed donepezil, the primary reason for discontinuation was an adverse event. Cognitive assessments revealed no significant worsening at 1 year, indicating that continuous donepezil treatment contributes to the maintenance of cognitive function.
