RESUMO
OBJECTIVE@#To compare the clinical efficacy between visual trephine arthroplasty assisted percutaneous transforaminal endoscopic discectomy (VPTED) and traditional percutaneous transforaminal endoscopic discectomy(PTED) in the treatment of lumbar disc herniation.@*METHODS@#The clinical data of 60 patients with lumbar disc herniation admitted from June 2019 to December, 2020 was retrospectively analyzed. There were 38 males and 22 females, aged from 26 to 58 years old with an average of (43.63±8.48) years, 47 cases were on L4,5 segment and 13 cases were on L5S1 segment. Among them, 32 were treated with VPTED (group A) and 28 were treated with traditional PTED (group B). The general conditions of all the patients were recorded, including intraoperative fluoroscopy times, operation time, hospital stay and surgical complications during follow-up. The arthroplasty area ratio was observed by sagittal CT at the middle level of the intervertebral foramen. Visual analogue scale (VAS) and Japanese Orthopaedic Association (JOA) score of low back pain, Oswestry disability index (ODI) were used to evaluate the clinical efficacy between two groups.@*RESULTS@#All patients were followed up from 9 to 15 months with an average of (12.10±1.16) months. There was no statistical difference of preoperative general data between two groups. The operation time, fluoroscopy times and hospital stay were (70.47±5.87) min, (13.66±1.34) times and (6.31±0.69) d in group A, and (90.71±7.66) min, (22.82±2.48) times and (6.54±0.92) d in group B. The operation time and intraoperative fluoroscopy times in group A were lower than those in group B(P<0.05). There was no significant difference in hospital stay between two groups (P>0.05). No obvious surgical complications were found during the follow-up in both groups. The arthroplasty area ratio in group A was (29.72±2.84)% and (29.57±2.20)% in group B, respectively, with no significant difference (P>0.05). There was no significant difference in VAS, ODI and JOA score between two groups before operation and at the final follow-up(P>0.05), but the final follow-up was significantly improved(P<0.05).@*CONCLUSION@#The two surgical methods have definite clinical efficacy in the treatment of lumbar disc herniation. Visual trephine arthroplasty assisted percutaneous transforaminal endoscopic discectomy has the advantages of high efficiency and rapidity when establishing the channel, and can significantly reduce the operation time and intraoperative fluoroscopy times.

RESUMO
<p><b>OBJECTIVE</b>To investigate the role of autophagy in MnCl2-induced apoptosis in human bronchial epithelial 16HBE cells.</p><p><b>METHODS</b>Cell proliferation was measured by MTT assay. Mitochondrial membrane potential (MMP) and apoptosis were measured by flow cytometry. Autophagic vacuoles were detected by fluorescence microscopy. Cellular levels of apoptosis and autophagy-related proteins were measured by western blotting.</p><p><b>RESULTS</b>16HBE cell proliferation was inhibited by MnCl2 in a dose- and time-dependent manner. MnCl2-induced 16HBE cell growth inhibition was related to MMP depolarization prior to the induction of apoptosis. Our data revealed that MnCl2-induced apoptosis in 16HBE cells was mediated by decreased expression of Bcl-2 and increased levels of cleaved caspase-3. It was observed that when we exposed 16HBE cells to MnCl2 in a dose-dependent manner, the formation of autophagic vacuoles and the levels of LC-3B-II were elevated. RNA interference of LC3B in these MnCl2-exposed cells demonstrated that MMP loss and apoptosis were enhanced. Additionally, the pan-caspase inhibitor Z-VAD-FMK increased the cellular levels of Bcl-2 and decreased apoptosis, but did not affect the cellular levels of LC3B in MnCl2-treated 16HBE cells.</p><p><b>CONCLUSION</b>MnCl2 dose- and time-dependently inhibits 16HBE cell proliferation and induces MMP loss and apoptosis. Autophagy acts in a protective role against MnCl2-induced apoptosis in 16HBE cells.</p>

<p><b>OBJECTIVE</b>To study the associations of pedestrian injuries with age, income and educational level in Shanghai and to analyze the relative disease burden.</p><p><b>METHODS</b>Information on pedestrian-related cases and deaths were collected from 494 hospitals and mortality registry systems from 1992 to 2010, and a multistage cluster sampling survey conducted in 2006. Logistic regression model was used in the analyses.</p><p><b>RESULTS</b>The age group of 5-9 had the highest mortality and morbidity among children. Mortality increased obviously among those aged 60 or above. Individuals with an educational level under the primary school and with the lower family average income were more likely to suffer pedestrian-related injuries. Multivariate Logistic analysis demonstrated that lower income and lower educational level increased the risk of pedestrian injuries with the odds ratio of 1.40 (95% CI: 1.15-1.71) and 1.70 (95% CI: 1.20-2-40), respectively. About 13.54% of the share of GDP for the healthcare, social security and welfare industries in Shanghai was occupied by the burden of pedestrian-related injuries in 2006.</p><p><b>CONCLUSION</b>Pedestrian-related injury has inverse association with victims' income and educational level. Children of 5-9 years old and adults over 60 with lower educational level and lower monthly income are the target persons to be intervened.</p>

Although neurophysiological and psychophysical proof of osseoperception is accumulating, histomorphometric evidence for the neural mechanisms of functional compensation following immediate and delayed implant loading is still lacking. For this randomized split-mouth study, six mongrel dogs randomly received one of four treatment protocols at 36 implant-recipient sites over 16 weeks (third maxillary incisor, third and fourth mandibular premolar): immediate implant placement and immediate loading (IIP+IL); delayed implant placement and delayed loading (DIP+DL); delayed implant placement and immediate loading (DIP+IL); and natural extraction socket healing (control). Histomorphometry was performed in the peri-implant bone and soft tissues within 300 µm around the implants. Immunocytochemistry and transmission electron microscopy were used to confirm the presence of neural structures and to reveal their ultrastructural characteristics, respectively. Myelinated nerve fibres densely populated the peri-implant crestal gingival and apical regions, although they were also identified in the woven bone and in the osteons near the implant threads. Compared with the control group in the mandible, the group that received IIP+IL showed a higher innervation (in N⋅mm⁻², 5.94 ± 1.12 vs. 3.15 ± 0.63, P<0.001) and smaller fibre diameter (in µm, 1.37 ± 0.05 vs. 1.64 ± 0.13, P=0.016), smaller axon diameter (in µm, 0.89 ± 0.05 vs. 1.24 ± 0.10, P=0.009) and g-ratio (0.64 ± 0.04 vs. 0.76 ± 0.05, P<0.001) in the middle region around the implants. Compared with DIP+IL in the mandible, IIP+IL had a higher nerve density (in N⋅mm⁻², 13.23 ± 2.54 vs. 9.64 ± 1.86, P=0.027), greater fibre diameter (in µm, 1.32 ± 0.02 vs. 1.20 ± 0.04, P=0.021), greater axon diameter (in µm, 0.92 ± 0.01 vs. 0.89 ± 0.03, P=0.035) and lower g-ratio (0.69 ± 0.01 vs. 0.74 ± 0.01, P=0.033) in the apical region around the implants. It may be assumed that the treatment protocol with IIP+IL is the preferred method to allow optimized peri-implant re-innervation, but further functional measurements are still required.

RESUMO
Objective To investigate the diagnosis and treatment of intracranial venous sinus thrombosis caused by trauma. Methods The clinical data of 13 patients had definite diagnosis by clinic and imaging, were analyzed retrospectively. Three patients received removal of hematoma and bone flap operation; 2 received anticoagulant therapy in early phase and intravenous thrombolysis; 2 accepted intrasinus interventional catheter-directed thrombolysis; ventriculoperitoneal shunt operation was performed in 1 patient for enjoying sub-optimal effects of conservative treatment; and the other 5 patients with transverse sinus embolism accepted conventional treatment for their symptom-free or having mild symptom. Results Intracranial venous sinus thrombosis caused by trauma was likely to locate in the superior sagittal sinus and transverse sinus; these patients mostly manifested as severe diffuse brain swelling combined with a fractured skull, epidural hematoma or intracerebral hematoma. Ten patients got clinical cure, 2 focal symptom and 1 mild mental retardation. Three days to 6 months after treatment, good results were noted in 8 patients performed DSA and in 5 patients performed MRV. Conclusion Early treatment should be given once the definite diagnosis is made in patients with intracranial venous sinus thrombosis caused by trauma, and anticoagulant and thrombolytic therapy are the main methods.
RESUMO
<p><b>OBJECTIVE</b>To investigate whether cadmium-induced oxidative stress in the kidney is influenced by zinc and selenium.</p><p><b>METHODS</b>Five groups of rats were maintained: (A) Cd (CdCl2, 400 micrograms.kg-1.day-1 intraperitoneal injection); (B) Cd + Zn (ZnCl2, 20 mg.kg-1.day-1 hypodermic injection); (C) Cd + Se (Na2SeO3, 350 micrograms.kg-1.day-1 via a stomach tube); (D) Cd + Zn + Se; (E) treated with physiological saline as a sham-handled control. The rats were given treatment for a period of 4 weeks. The activities of superoxide dismutase (SOD), glutathione peroxidase (GH-Px), catalase (CAT), and the level of malondialdehyde (MDA) in the kidney tissue were measured to assess the oxidative stress. Urinary lactate dehydrogenase (LDH) activity was used as an indicator of tubular cell damage caused by lipid peroxidation.</p><p><b>RESULTS</b>In group C and D, activities of SOD (110.5 +/- 5.2, 126.8 +/- 7.0; P < 0.05) and GSH-Px (85.7 +/- 4.9, 94.6 +/- 7.3; P < 0.05) were higher than those in group A (84.7 +/- 3.3; 56.9 +/- 3.8); and in group B, only the activity of GSH-Px (80.0 +/- 4.3, P < 0.01) increased in comparison with that in group A (56.9 +/- 3.8). Significant increase of MDA (P < 0.05) was seen in group B (31.1 +/- 4.7) and C (35.0 +/- 4.1) when compared with control values (17.2 +/- 1.8). No difference was found in the level of MDA between group D (18.9 +/- 2.6) and control. The activity of LDH in urine of control group (0.06 +/- 0.02) was lower than that of group A (0.46 +/- 0.19, P < 0.05), B (0.10 +/- 0.05, P < 0.05) and C (0.14 +/- 0.07, P < 0.05), and there was no significant change between control (0.06 +/- 0.02) and group D (0.08 +/- 0.02).</p><p><b>CONCLUSION</b>Zinc or selenium could partially alleviate the oxidative stress induced by cadmium in kidney, but administration cadmium in combination with zinc and selenium efficiently protects kidney from cadmium-induced oxidative damage.</p>
