Objective To explore the role of intracellular Ca~(2+) in inhibition of axonal outgrowth,which could learn more about the signal transduction mechanism of Nogo-A inhibiting axonal outgrowth. Methods Using laser confocal microscope,intracellular calcium level in cerebellar granule neurons after Nogo-A added in different times was measured and the effect of Nogo-A inhibiting axonal outgrowth when priming nimodipine was observed. Results The concentration of Ca~(2+) increased in 5 minutes after Nogo-A added,and reached to peak in 30 minutes,then decreased gradually,90 minutes later dropped to normal level.When priming with nimodipine,the axonal inhibition by Nogo-A was partly abrogated compared with control.Conclusion Ca~(2+) may participate in the signal transduction of Nogo-A inhibiting axonal outgrowth.

Objective To study the effect of amelogenin (AML)on the migration,adhesion and proliferation of periodontal ligament stem cells (PDLSCs).Methods STRO-1 +PDLSCs were selected by Flow cytometer.The transwell system was used to detect the effect of AML on migration of PDLSCs.Cells attachment assay was used to detect the effect of AML on adhesion of PDLSCs.MTT was used to detect the effect of AML on the proliferation of PDLSCs.Results The results of transwell showed that AML could induce the migration of PDLSCs with positive correlation.Cells attachment assay showed that the adhesion of PDLSCs was effected by AML as well,and the effect was in-creased with the extension of incubation time.Results of MTT showed that AML could promote the proliferation of PDLSCs in a dose depend-ent manner.Conclusion AML could increase the proliferation,adhesion and migration potential of PDLSCs.

Objective To explore the expression of discoidin domain receptor 1 (DDR1) in rats with pulmonary fibrosis induced by paraquat (PQ) poisoning, and its relationship with the expression of transforming growth factor-β1 (TGF-β1). Methods 120 Sprague-Dawley (SD) rats were divided into control group and 20, 40, and 80 mg/kg PQ poisoning groups (each n = 30). Pulmonary fibrosis induced by PQ poisoning model was reproduced by one time administration of 20, 40, 80 mg/kg of 20% PQ, and the rats in control group were given 4 mL normal saline. Fifteen rats in control and different doses of PQ groups were sacrificed at 7 days and 21 days after intragastric administration, and lung tissues were collected. Pulmonary fibrosis was observed after hematoxylin-eosin (HE) staining. The immune-histochemical method was used to determine the expressions of DDR1 and TGF-β1. The relationship between the expression of TGF-β1 and DDR1 was analyzed by Pearson correlation analysis. Results The rats in control group were active, and no pathological changes in lung tissue were found. The rats in PQ groups became shortness of breath, bristles, and slow reaction etc. 0.5 hours after intragastric administration. After 7 days, the lung tissue was dark red, hard texture, appearance of yellow soil fiber nodules and obsolete hemorrhage, destruction of alveolar structure. The extent of lung injury increased gradually with the time of poisoning and the increase of PQ dose. It was shown by immune-histochemical staining that the control group had only a small amount of DDR1 and TGF-β1 positive expressions; in PQ groups, there were a large number of DDR1 and TGF-β1 positive expression particles in the alveolar wall, pulmonary interstitial and alveolar cavity. It was displayed by quantitative analysis that compared with the control group, DDR1 and TGF-β1 expressions were significantly increased in 20, 40, 80 mg/kg PQ groups with time- and dose-dependent [DDR1 (integral A value): 0.221±0.014, 0.249±0.021, 0.364±0.016 vs. 0.121±0.036 at 7 days; 0.247±0.025, 0.321±0.015, 0.432±0.027 vs. 0.139±0.021 at 21 days; TGF-β1 (integral A value): 0.230±0.016, 0.265±0.015, 0.339±0.016 vs. 0.129±0.032 at 7 days; 0.248±0.011, 0.295±0.016, 0.399±0.026 vs. 0.119±0.026 at 21 days; all P < 0.05]. It was shown by Pearson correlation analysis that DDR1 expression was positively correlated with TGF-β1 expression with the increase of PQ dose and poisoning time (DDR1 with TGF-β1: r = 0.996, P < 0.000; DDR1 with PQ dose: r = 0.985, P < 0.000; DDR1 with poisoning time: r = 0.989, P < 0.000; TGF-β1 with PQ dose: r = 0.992, P < 0.000; TGF-β1 with poisoning time: r = 0.972, P < 0.000). Conclusions The expression of DDR1 in the lung tissue in PQ poisoning rats showed a time- and dose-dependent change, and it was positively correlated with TGF-β1 expression. DDR1 may be involved in the process of pulmonary fibrosis induced by PQ poisoning.

Pancreatic neuroendocrine tumors(pNETs)have a low prevalence,and may be func-tional as secreting biologically active substance or nonfunctional. With the increased understanding of this disease,new technologies are being developed for diagnosis and treatment. However,surgical excision re-mains the primary therapy for localized tumors and the cure rate is not ideal yet. In choosing the appropri-ate therapy for locally advanced/ metastatic pNETs,medical management strategy should be made in a multidisciplinary context. In addition to chemotherapy,there have been significant advances in targeted mo-lecular therapy.

Objective To investigate the methods and therapeutic effects of anterolateral thigh perforator free flaps for reconstruction of soft tissue defects around the ankle.Methods A retrospective case series study was made on 30 patients treated with anterolateral thigh perforator free flaps for traumatic soft tissue defects around the tibia between January 2010 and June 2016.There were 22 males and eight females,with the age range of 16-58 years [(41.5 ± 1.2) years].Dimension of the soft tissue defect ranged from 9 cm ×4 cm to 23 cm × 12 cm.Flap stabilization time,flap survival rate,postoperative complications,second plastic surgery rate,and ankle joint function by Baird-Jackson score were recorded.Results All patients were followed up for (13.0 ± 5.4) months (range,6-24 months).Time for flap stabilization was (6.5 ± 1.1) days.All flaps survived except in one patients with flap loss due to postoperative arterial thrombosis.Postoperatively,one patient had arterial crisis,one had venous thrombosis,and one presented sinus formation due to infection.No second plastic surgery was carried out.According to the Baird-Jackson score,the results were excellent in 25 patients and good in five.Conclusion Anterolateral thigh perforator free flaps for reconstruction of traumatic soft tissue defects around the tibia has advantages of easy harvesting and survival,less postoperative complications,less second surgery,and good function recovery.

Objective Normal radiographic scaphoid lunate (SL) interval is thought to be 2 mm and abnormal SL interval is a prerequisite for diagnosing scapholunate instability. However, in the routine neutral rotation posterior anterior (PA) view of the wrist, the frequent overlapping between scaphoid and lunate precludes proper interpretation of the interval. Moreover, the normative data in Chinese population has not been reported. We developed a new but simple technique in radiological assessment to evaluate the normal SL interval in Chinese. Methods With the forearm in neutral rotation, a PA view of the wrist was taken using a mobile Xiscan. A radiolucent cushion was put underneath the hypothenar eminence so that the metacarpal arch of hand became parallel to the receiver table of the Xiscan. The normal supination posture of the wrist was thus corrected and the true SL interval was revealed. Two hundred normal wrists were examined; there were 46 female and 54 male healthy Chinese subjects, with age ranging from 18 to 80. The SL interval was determined with wrist in neutral, radially deviated and ulnarly deviated position using the cushioned neutral rotation PA view. The length of capitate, hamate and lunate were also measured to correlate with the SL interval. Results By using the standard PA view, the SL interval could not be determined in 60% of cases. Using the new assessment method, the optimal intervals were seen in all cases. The average SL interval was (2.07?0.65) mm. There was no significant gender difference. The measurement of ulnar variance was not affected by the new method. Conclusion The modified (Cushioned) PA view was the optimal radiological assessment method for true SL interval. There was wide variation of the normal value of the SL interval in Chinese population.
