Objective To study the effects of hyperbaric oxygen (HBO) preconditioning (PC) on motor function and mitochondrial apoptosis after spinal cord injury (SCI) in rats.Methods Thirty-six healthy,male Wistar rats were randomly divided into 3 groups (each n =12):a control (CON) group,an SCI model group and an HBO-PC group.The SCI group and the HBO-PC group after 7 sessions of HBO-PC treatment were subjected to SCI modeling using Allen's method.The CON group was not given any special treatment.Two weeks after the modeling,Basso,Beattie,and Bresnahan BBB scale was used to rate the rats' locomotor function,and the T8 segment of the rats' spinal cords was removed.After extracting total RNA from the spinal cord tissue,real-time quantitative PCR was used to detect the mRNA expression levels ofcaspase-3,cytochrome C (CYC),Bak,Bax,Bcl-x and Bcl-2 in the spinal cord tissue.Results Two weeks after modeling,compared with the CON group,the average BBB locomotion score of the SCI model group had decreased.In contrast,caspase-3,CYC,Bak and Bax mRNA expressions had increased significantly.Compared with the CON group,the average BBB locomotion score of the HBO-PC group had decreased,caspase-3 expression had increased,and Bax mRNA expression had decreased,but the differences in the changes between the two groups were not statistically significant.Bak mRNA expression increased and CYC expression decreased,and the difference between the two groups was statistically significant.Compared with the SCI model group,the average BBB locomotion score of the HBO-PC group increased while caspase-3,CYC,Bak and Bax mRNA expressions decreased,but none of these differences between the two groups was statistically significant.Bak mRNA expression increased and CYC mRNA expression decreased,and those differences between the two groups were statistically significant.Bcl-x and Bcl-2 mRNA expression in the CON,HBO-PC and SCI model groups were significantly different.Conclusion HBO-PC can reduce the loss of motor function after SCI,at least in rats.The mechanism may be related to reducing neuron mitochondrial apoptosis.

Objective To localize the tibial attachment of the posterior cruciate ligament (PCL) on the magnetic resonance imaging (MRI) and provide parameters for clinical PCL reconstruction.Methods We retrospectively analyzed 524 patients with intact tibial PCL attachment who had undergone knee MRI from January 2010 to January 2016.They were 286 men and 238 women with an average age of 35 years (from 20 to 50 years).The size and positions of the tibial PCL attachment were measured on the sagittal and coronal MRI slices.The differences were analyzed between different genders.Results On the sagittal slices,the mean distance from the central tibial PCL attachment to the posterior edge of the tibial plateau was 17.9 ± 3.0 mm and the mean anteroposterior diameter of the tibial PCL attachment was 9.7 ± 2.4 mm,with those for males significantly larger than for females (P ＜ 0.05).The above mean values when expressed as a percentage of the posterior tibial slop were 79.9％ ±4.5％ and 43.7％ ± 9.6％,respectively,showing no significant differences between males and females (P ＞ 0.05).On the coronal slices,the distances from the central tibial PCL attachment to the medial and lateral edges of the tibial plateau were 33.5 ± 3.1 mm and 37.4 ±4.1 mm,respectively,and the mediolateral diameter of the tibial PCL attachment was 12.0 ± 1.6 mm,with those for males significantly larger than for females (P ＜ 0.05).The above mean values when expressed as a percentage of the mediolateral diameter of the tibial PCL attachment were 47.4％ ± 3.2％,52.7％ ±3.1％ and 16.9％ ± 1.7％,respectively,showing no significant differences between males and females (P ＞ 0.05).Conclusions On knee MRI images,the distance from the central tibial PCL attachment to the posterior edge of the tibial plateau is about 17.9 mm,the anteroposterior diameter of the tibial PCL attachment around 9.7 mm,and the mediolateral diameter of the tibial PCL attachment roughly 12.0 mm.These measurements for males are larger than for females.

Objective To explore the effect of Botulinum toxin type A (BTX-A) injection combined with rehabilitation training and medicated bath on spasm for children with cerebral palsy. Methods 80 children with spastic and mixed cerebral palsy were randomly divided into two groups with 40 cases in each group. The control group received physical therapy, and the observation group received BTX-A injection and rehabilitation training and medicated bath. They were assessed with modified Ashworth scale (MAS) and Gross Motor Function Measure (GMFM-88) before and 3 months after treatment. Results The scores of MAS and GMFM were better in 2 groups after treatment (P<0.05) and the observation group was better than that of the control group (P<0.05). Conclusion BTX-A injection combined with medicated bath can reduce muscle tension, improve gross motor function of children with spastic and mixed cerebral palsy.

Objective To evaluate the efficacy and safety of the hyper-CVAD/MA regimen as an intensified treatment option for 28 T cell and aggressive/highly aggressive B cell NHL in Chinese patients. Methods Clinical data of 28 NHL patients treated with hyper-CVAD/MA regimen from Jan 2005 to Sep 2008 were retrospectively analyzed. Results 27 NHL patients were available for the efficacy analysis, with a response rate of 70.4 %. For the 13 B cell lymphoma cases, the response rate was 84.6 %. The main toxicity was Grade Ⅲ or Grade Ⅳ myelosuppression in all cases and 2 treatment related deaths. Conclusion Hyper-CVAD/MA regimen had a high response rate in T cell and aggressive /highly aggressive B cell NHL lymphoma, companied by significant toxicity when treating Chinese patients. Further clinical practices are needed to pick up a suitable dose which can balance efficacy and safety.

Objective:To prepare 68Ga-2-(4, 7-bis(carboxymethyl)-1, 4, 7-triazonan-1-yl)pentanedioic acid (NODAGA)-YHWYGYTPQNVI (GE11) and evaluate its feasibility of PET imaging for pancreatic cancer. Methods:GE11 peptide was conjugated with NODAGA and then labeled with 68Ga. The labeling yield, radiochemical purity, hydrophilicity, stability and specificity in vitro were determined. Human pancreatic cancer BxPC3 nude mice models ( n=9) were established. MicroPET imaging was then obtained after 30 and 90 min, and mice were sacrificed at 90 min to acquire the radioactivity distribution of main organs and tumors. Pair t test was used to analyze the data. Results:The labeling yield was (73.5±5.4)% and radiochemical purity was more than 98%. After incubation 120 min in mouse serum at 37 ℃, radiochemical purity was more than 92%. The uptake was specific in BxPC3 cell lines. MicroPET images showed that 68Ga-NODAGA-GE11 could accumulate quickly in tumor. Value of tumor uptake was significantly higher than that of normal pancreas at 90 min ((1.38±0.25) vs (0.49±0.07) %ID/g; t=12.67, P<0.05), and the radio-uptake of blood, muscle and bone was lower than that of tumor. Conclusions:68Ga-NODAGA-GE11 is easy to be prepared with high radiochemical purity and good stability, and can specifically target BxPC3 xenograft tumor. However, due to the high uptake in the kidneys and liver, the value of 68Ga-NODAGA-GE11 in PET imaging for pancreatic tumor needs further study.

Objective: To compare the biomechanical characteristics of four-implants mandibular overdentures supported by Locator attachment or bar-clip attachment under different mechanical loads using three-dimensional finite element analysis method. Methods: Two different models of four-implants supported mandibular overdentures using Locator attachment and bar-clip attachment (hereinafter called Locator model and bar-clip model) were established. Each model was subjected to five different mechanical loading conditions: 100 N vertical loading in central incisor (vertical load of incisor), 100 N vertical loading or oblique loading in canine (vertical or oblique loads of canines), 100 N vertical or oblique loading in mandibular first molar (vertical or oblique loads of mandibular first molar). The stress distributions in implants, peri-implant bone and mucosa were recorded under the above five conditions to evaluate the effects of different attachments on the biomechanical properties of implant-supported mandibular overdentures. Results: Regardless of loading conditions and types of attachments, the stress concentration in implants were located at the neck of implants, and the stress concentration in peri-implant bone was located in the cortical bone. The stress values in mucosa were always much smaller than those in implants and cortical bone. Regardless of loading positions (on canine or on mandibular first molar), the maximum stress at the bone interface around the implant under lateral loading was much higher than that under vertical loading. Under various loading conditions, the stress in implants and cortical bone of the Locator model (the highest von Mise stress value was respectively 79.5 and 22.3 MPa) were lower than that of bar-clip model (the highest von Mise stress value was 110.3 and 28.7 MPa respectively) while the maximum compressive stress in mucosa (0.198 MPa) in Locator model was slightly higher than that in the bar-clip model (0.137 MPa). Conclusions In clinical practice, the lateral force applied to the implant-retained overdenture should be minimized to avoid complications caused by pathological loads. Under the same loading condition, the stress distributions in overdenture using Locator attachment are more dispersed, which is more conducive to long-term stability of implants.
