In this paper,the research results of mycophenolate mofetil for children with kidney disease are summarized.

BACKGROUND:Previous studies have found that the expression level of miR-486 in glioma stem cels (CD133+) is significantly down-regulated compared with that in glioma non-stem cels (CD133-), but the effect of down-regulation of miR-486 on CD133+ cels remains unclear . OBJECTIVE: To explore the effect of miR-486 on CD133+ cels. METHODS:CD133+ glioma stem cels and CD133- glioma cels were separated from U87 cels by flow cytometer. miR-486 overexpression glioma stem cels were constructed by lipofection transfection. RESULTS AND CONCLUSION:After sorting and purification, the content of the CD133+ fraction was enriched up to 83.5%. The expression level of miR-468 in CD133+ glioma stem cels was obviously down-regulated compared with that in CD133- glioma cels. CD133+ glioma stem cels overexpressing miR-486 were fabricated successfuly. Results from in vitro experiments showed that miR-486 overexpression could dramaticaly decrease the proliferation of glioma stem cels, induce a cel cycle arrest in G1/S phase for CD133+ glioma stem cels and promote cel apoptosis. These findings suggest that miR-486 can be a suppressor of glioma stem cels, which offers a novel potential therapeutic target for glioma stem cels and human glioma.

BACKGROUND:Severe knee pain after total knee arthroplasty is an important factor for the poor recovery of knee function after replacement. How to give a satisfactory postoperative analgesia scheme is currently a hot research. OBJECTIVE:To explore the clinical effects of different analgesic program methods on postoperative pain and functional recovery in patients undergoing total knee arthroplasty. METHODS:From March 2010 to February 2014, 60 patients with unilateral knee arthroplasty were randomly divided into three groups:epidural analgesia group, intravenous analgesia group, and continuous femoral nerve block analgesia group. 20 patients in each group received corresponding postoperative analgesia. Visual Analogue Scale score before replacement, 1, 6, 24, 48 and 96 hours after replacement, the recovery of range of motion at 24, 48 and 72 hours after replacement, KSS score of the knee and adverse reactions after replacement were recorded and compared in each group. RESULTS AND CONCLUSION:Compared with the preoperative data, Visual Analogue Scale score was reduced in continuous femoral nerve block analgesia group at 1, 24, 48 and 96 hours after replacement (P<0.05). The recovery of range of motion was best in the continuous femoral nerve block analgesia group, fol owed by epidural analgesia group, and it was poorest in the intravenous analgesia group (P<0.05). Compared with the preoperative data, postoperative KSS scores increased at 1 and 3 months after replacement in the three groups (P<0.05). Compared with the continuous femoral nerve block analgesia group, knee joint function score was decreased in the intravenous analgesia group (P<0.05). Results verified that continuous femoral nerve block analgesia had good overal effects, helped the recovery of postoperative joint function, and was safe and reliable.

Objective To provide data support for safe and accurate lower cervical pedicle screw implantation by observing the lower cervical pedicle and its relationship between the adjacent spinal cord, endorhachis, nerve root and vertebral artery, particularly its relation-ship between the endorhachis and epidural sinus. Methods Measured the C3 ~ C7 cervical sample of 32 adult with vernier caliper and pro-tractor, including the distance between cervical pedicle and its upper and lower nerve root, the distance between cervical pedicle and en-dorhachis, the distance between cervical pedicle and vertebral artery, and the distance between cervical pedicle and epidural sinus. Results The distance betweencervical pedicle and its upper nerve root was 1. 18~1. 40 mm, the distance between cervical pedicle and its lower nerve root was 2. 33~3. 11 mm;the distance between cervical pedicle and endorhachis was 2. 75~3. 33 mm;and there was nearly no distance be-tween cervical pedicle and vertebral artery and epidural sinus. Conclusion Cervical pedicle has a very close relationship with spinal cord, endorhachis, vertebral artery and nerve root, and the cervical pedicle is narrow and small. Therefore, it requires fully assess accroding to in-dividualization so as to prevent injury of important anatomical structures.

Acromegaly is mostly caused by a pituitary adenoma secreting growth hormone ( GH ) , which leads to a wide range of endocrine morbidities, with an insidious onset and slow progression.A long-term overproduction of GH results in elevated insulin-like growth factor-1 ( IGF-1 ) level, which in turn, would cause target organ damage and an increased risk for mortality and decreased quality of life.Herein, the literature regarding the progress of drug therapy for acromegaly in recent five years is reviewed.

Objective To investigate the effects of solution focused approach on the hope level of patients with epilepsy. Methods A total of 83 patients with epilepsy were randomly divided into the observation group and the control group, 42 cases in the observation group, 41 cases in the control group. The control group was given traditional nursing care, the observation group was given nursing intervention based on solution focused approach. Two groups were surveyed with Herth Hope Index (HHI), Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) before and after the intervention. Results Before the intervention, HHI of the observation group and the control group scored 24.95 ± 1.92 and 24.56 ± 3.23 respectively. After intervention the scores increased to 28.85 ± 1.81 and 25.31 ± 3.35. After intervention, HHI and each dimension of the observation group scored higher than those before intervention and the control group, the difference was statistically significant (t=-4.75, 5.84, P < 0.01). Before the intervention, SAS scores in the observation group and the control group were 56.41 ± 5.97 and 56.28 ± 6.14, SDS scores were 53.72 ± 8.41 and 53.47 ± 8.26, there was no statistically significant difference between the 2 groups (t=0.09, 0.13, P > 0.05). After intervention SAS scores the observation group and the control group were 41.65 ± 6.22 and 49.72 ± 5.86, SDS scores were 44.57 ± 5.83 and 49.73 ± 6.24, there was significant difference between 2 groups (t=5.67, 3.20, P < 0.01). Intra group comparison of the observation showed that there was significant difference in SAS and SDS scores before and after the intervention (t=10.27, 5.36, P < 0.01). Intra group comparison of the control group also showed statistical difference in SAS and SDS scores (t=4.65, 2.17, P<0.05 or 0.01). Conclusions The solution focused approach can improve the psychological status of patients with epilepsy, improve the level of hope, promote the rehabilitation of patients.

OBJECTIVE:To study the effects of salvianolate on the expression of vascular endothelial growth factor (VEGF) and matrix metalloproteinase-9(MMP-9)in lung tissue of mice with lung cancer. METHODS:C57BL/6 mice were randomly divid-ed into model group (normal saline),positive control group (cyclophosphamide 50 mg/kg) and salvianolate low-dose,medi-um-dose and high-dose groups(20,40,80 g/kg)with 10 mice in each group. They were ig 1 000 mg/kg urethane,twice a day, for consecutive 4 weeks to establish lung cancer model. After modeling,they were given relevant medicine intragastrically once a day for consecutive 14 d. Mice behaviors,symptoms,body weight,tumor inhibition rate,spleen index,thymus index,and the ex-pressions of VEGF and MMP-9 in lung tissue among groups were compared. RESULTS:The activity of mice in model group disap-peared,dull coat color,preferred crowding together;the above-mentioned phenomenon improved in positive control group and sal-vianolate different dose groups. The body weight of mice in positive control group,salvianolate low-dose group,medium-dose group and high-dose group were(21.01±2.95)g,(20.89±3.14)g,(21.03±3.02)g,(21.24±3.17)g;and the tumor inhibition rates were(41.12±15.42)%,(36.92±10.42)%,(39.41±12.39)% and(37.19±10.39)%;compared with model group,spleen index,thymus index,and the expressions of VEGF (except for positive control group) and MMP-9 in other 4 groups decreased (P<0.05). CONCLUSIONS:Salvianolate shows obvious inhibitory effects on mice with lung cancer,which may be related to in-hibiting expressions of VEGF and MMP-9 in lung tissue.

Angioimmunoblastic T-cell lymphoma (AITL) is a rare subtype of peripheral T-cell lymphoma (PTCL) with aggressive behaviour and poor prognosis.Due to the rarity of the disease,few prospective controlled randomized clinical trials were conducted,and the standard therapeutic option for AITL has not been established.Although conventional anthracycline-based chemotherapy achieves response rates of up to 50 ％,most of the patients relapse,the median survival time and overall survival rate are unsatisfactory.Recent studies have demonstrated that hematopietic stem cell transplantation and cyclosporine show promising efficacy in the treatment of AITL.This current review mainly focused on the advance of treatment for AITL.

Objective:To observe the effect of Er:YAG laser on the proliferation of human periodontal ligament fibroblasts(hP-DLFs).Methods:Human periodontal ligament fibroblasts were cultured in vitro and identified by immunohistochemistry.The cells of 5th passage were divided into 5 groups.The cells in group A without treatment were used as the controls,in group B,C,D and E were treated with Er:YAG laser of 10 Hz at 50 mJ,100 mJ,150 mJ and E-200 mJ for 1 s respectively.The proliferation of the cells was examined on day 1,3,5,7,9 by CCK-8.Results:The proliferation of hPDLFs in group B,C,D and E increased more than that in group A(P <0.05)5 d after Er:YAG laser radiation.Conclusion:Low intensity of Er:YAG laser radiation can promote the prolifera-tion of human periodontal ligament fibroblasts.

Objective To investigate the sleep problems and related affecting factors of primary or possibly symptomatic school-aged children with epilepsy.Methods 54 epilepsy children(7 to 12 years old) and the general 54 healthy children whose gender and age were strictly matched with epilepsy group were investigated by using the chinese version of CSHQ.Results ① The total CSHQ score and 6 subscale scores (bedtime resistance, sleep onset delay,sleep anxiety, night wakings, parasomnias, and daytime sleepiness)were significantly higher in the epilepsy group(P<0.05).② In the epilepsy group, different age groups had statistical difference in the total CSHQ score and 4 subscale scores(sleep resistance, sleep onset delay, sleep duration and sleep anxiety) (P<0.05).The seizure controlled group and the uncontrolled group had statistical difference in the total CSHQ score and all subscale scores, except sleep onset delay(P<0.05).There were statistically significant differences in the total CSHQ score and all subscale scores, except sleep-disordered breathing in different seizure frequency groups(P<0.05).Different seizure type groups had statistical difference in the total CSHQ score and 4 subscale scores(sleep resistance, sleep duration, sleep anxiety and daytime sleepiness)(P<0.05).Different seizure time groups had statistical difference in the total CSHQ score and 5 subscale scores(sleep resistance, sleep onset delay, sleep duration, sleep anxiety and night waking)(P<0.05).Monotherapy group and polytherapy group had statistical difference in the total CSHQ score and 4 subscale scores(sleep onset delay, night waking, parasomnias and daytime sleepiness) (P<0.05).③ Multiple linear regression analysis showed that the main influencing factors of the total CSHQ score and some subscale scores were gender, age, control of seizure, frequency of seizure, type of seizure, time of seizure and the number of drug taking.Conclusion Children with epilepsy compared with healthy children are more likely to have sleep problems, and the occurrence of sleep problems may be related to many factors.
