Acta Universitatis Medicinalis Anhui 2015;(8):1146-1149
Objective To investigate the common etiologies,sports and learning situation of children in Nantong with short stature,and discuss the relationship between the two. Methods Did a retrospective analysis of 108 cases of children with short stature in Nantong University′s affiliated hospital since January 2012. Through detailed past illnesses, physical examination, laboratory tests, diagnose short stature and clarify the cause. Did a questionnaire to these children with short stature about sports and learning situation. Use statistical methods like multivariate Logis-tic regression analysis and link analysis to analyze sports and learning situation of children in Nantong with short sta-ture and find the relation with the etiology. According to the principle of group matching,the control group elected representative of 108 children. Results In 108 cases, 61 cases were because of growth hormone deficiency (GHD), accounting for 56. 5% ; 47 cases were because of non-growth hormone deficiency (NGHD), accounting for 43. 5% . Logistic regression analysis showed that participation in physical exercise was a protective factor. Rest-less anxiety and inattention were as risk factors,and these make a lot(P < 0. 001, OR = 7. 483, 95% CI = 2. 620 ~21. 374). There was no significant relation between common cause and sports, learning situation ( P > 0. 05). Conclusion Various types of sports (basketball, badminton, running, cycling) are protective factors for children of short stature. Restless anxiety and inattention are risk factors for children with short stature. Whether there is growth hormone deficiency or not, children with short stature should increase the right exercise as much as possible and avoid or reduce exposure to these risk factors.

Objective To investigate whether baicalein inhibits the proliferation, cell cycle of and pseudopod formation in A431, a skin squamous cell carcinoma cell line, by suppressing the expression of ezrin protein. Methods A431 cells were grouped to be transfected with ezrin-targeting siRNA (siRNA group), treated with baicalein of 5, 10, 20, 40 μmol/L, respectively (baicalein group), or remain untreated (control group). After additional culture, wound healing assay and Transwell assay were performed to observe the migration and invasion of A431 cells, RT-PCR to detect the mRNA expression of ezrin in A431 cells, Western blot and immunoflu-orescence to measure the expression of ezrin protein and its phosphorylation. The pseudopod formation in A431 cells was observed by using scanning electron microscopy. Results After 24-hour culture, wound healing assay displayed that the percent wound closure was 13.3 ± 1.7, 7.6 ±1.6 and 5.9 ± 1.3, respectively, in A431 cells treated with baicalein of 5, 10, 20μmol/L, significantly lower than that in untreated A431 cells (16.3 ± 2.3, all P < 0.01), and the inhibition of baicalein on the migration of A431 cells was concentration-dependent. In the Transwell assay, a significant decrease was observed in the number of A431 cells per high power field permeating through the artificial basement membrane in the groups treated with baicalein of 5, 10, 20 μmol/L for 48 hours compared with the control group (46.5 ± 3.8, 34.3 ± 3.4, 25.3 ± 2.3 vs 56.3 ± 3.8, all P < 0.01), whereas no significant difference was noted between these baicalein-treated groups and siRNA-transfected group (28.3 ± 2.1, all P > 0.05). RT-PCR analysis showed that the mRNA expression of ezrin in baicalein-treated A431 cells significantly decreased compared with that in untreated cells (all P< 0.01), but showed no difference from that in siRNA group (P > 0.05). A statistical difference was also observed in the expression of ezrin and phosphorylated ezrin protein between baicalein-treated A431 cells and untreated cells (all P< 0.05), but not between 40 μmol/L baicalein-treated A431 cells and siRNA-transfected cells (P> 0.05). Furthermore, the suppression of baicalein on ezrin protein and mRNA expression was concentration dependent. The number of pseudopod per cell was significantly lower in 20 μmol/L baicalein-treated A431 cells and siRNA-transfected cells than that in untreated A431 cells (5.3 ± 1.9, 4.5 ± 2.8 vs 22.6 ± 2.8, both P < 0.01), while no significant difference was observed between the former two groups of cells (P > 0.05); the length of pseudopodia also reduced in baicalein-treated cells. Conclusions Baicalein may inhibit the proliferation and invasion of A431 cells by directly or indirectly suppressing the expression of ezrin and phosphorylated ezrin, which in turn contributes to the effect of baicalein against tumor proliferation and metastasis.

Objective To explore the safety and efficacy of the Wingspan stenting of basilar artery atherosclerosis stenosis though the analysis of single center massive clinical data. Methods Ninety one consecutive patients received Wingspan stenting because of basilar artery stenosis in our center from July 2007 to April 2013. The patients were classified into three groups:early term (n=30), middle term (n=30), and late term (n=31) according to the operation time in our center. The basic clinical data and the factors which may affect the ischemic events were retrospectively analysed, t test and Chi?Square test were used to analyze the factors related to the periprocedural ischemic complications. Results All of patients were stented successfully and the technical success rate was 100%(91/91). The mean stenosis was reduced from (82.2 ± 5.8)% to (15.9 ± 5.7)%; strokes or death happened in 13 cases within 30 days, including perforator stroke in 8 patients(8.8%, 8/91), thrombosis in 4 patients(4.4%, 4/91), subarachnoid hemo rrhage in 1 patient(1.1%, 1/91), 2 patients with disabling or fatal strokes. Lesions involving in the middle segment of basal artery (P=0.049), long?segment disease (P=0.002), severe stenosis (P=0.001) may be a risk factor affecting perioperative ischemic stroke, and the surgeons' surgical technique was not risk factors for ischemic complications (P=1.000). Seventy seven patients (84.6%, 77/91) had the clinical follow?up and the mean follow?up period was (31.3±15.1) months. Four patients suffered from posterior circulation strokes during the clinical follow?up , one of them (1.3%, 1/77) had disabling stroke, another 3 patients (3.9%, 3/77) suffered from TIA. The 2?year accumulate probability of stroke (any stroke or death within 30 days and stroke in the territory of the qualifying artery beyond 30 days)was 16%(95%CI, 8.2%to 23.8%). Forty six patients had the imaging follow?up and the mean follow?up period was(9.5±8.3)months, 6 patients(13.0%,6/46) had in?stent restenosis (ISR) and 2/6 patient had the symptomatic ISR. Conclusions The stroke or death rate of symptomatic basilar atherosclerosis Wingspan stenting within 30 days is high, but the disabling or fatal stroke rate is low. The middle segment of basilar artery involved, the long stenosis, the severe atherosclerosis may be the factors related to the periprocedural ischemic strokes. The incidence of disabling or fatal strokes was low following Wingspan stenting.

Objective To evaluate one-stage arthroscopic reconstruction of anterior crueiate ligament (ACL)and posterior cruciate ligament(PCL)using Achilles tendon-bone allografts. Methods From July 2000 to February 2005.we treated 15 patients(11 males and 4 females)whose ACL and PCL were ruptured at one knee but the eontralateral knee was intact.Their associated meniscus injuries were treated arthroscopically according to established procedures prior to ligament reconstruction.Thirty Achilles tendon-bone allografts were used to reconstruct torn ACL and PCL in 15 knees at one stage.Reconstruction of both ligaments was performed at subacute or chronic phase(>3 to 8 weeks)in 12 casses,and at acute phase in 3 cases(<3 weeks).All knees were graded pre-and postoperatively using the International Knee Documentation Committee(IKDC)and Lysholm scoring systems.At follow-up,functions were evaluated for all patients and compared with those of the contralateral healthy knee. Results All patients were followed up for a minimum of 3 years(mean,38 months).Preoperatively,the IKDC ratings showed all the injured knees were severely abnormal.At final postoperative f0Uow-up,9 knees received a normal rating,5 a nearly normal one and 1 an abnormal one.The differences in Lysholm score were statistically significant (t=15.660,P<0.05)between pre-and postoperative analyses.The most noticeable postoperative complication was a short localized fever coupled with arthroedema in 1 case. Conclusions Achilles tendon-bone allograft offers an alternative for simultaneous arthroseopic reconstruction of ACL and PCL.However,problems inherent in allograft tissues entail further investigation to ensure future application.
