| 2 | The Differences in Lower Extremity Joints Energy Dissipation Strategy during Landing between Athletes with Symptomatic Patellar Tendinopathy(PT)and without Patellar Tendinopathy(UPT)显示文摘Patellar tendinopathy is a clinical symptom of patellar tendons characterized by local pain in the front of the knee joint.It is common among basketball and volleyball players.Patients with patellar tendinopathy may exhibit different landing strategies during landing compared to healthy individuals.The purpose of this study was to compare the differences in lower limb joint energy dissipation(eccentric work)values for the symptomatic patellar tendinopathy(PT)athletes and no patellar tendinopathy(UPT)athletes during single-leg landing.A total of 26(PT:13,UPT:13)semi-professional male basketball and volleyball player’s kinetic data were collected during the landing phases.Joint work was calculated by the integral of joint power over time.In this study,the result showed that the ankle joint means energy dissipation(p<0.001)and total energy dissipation(p<0.001)of PT were significantly greater than UPT.Compared to the UPT athletes,the PT athletes showed smaller knee joint mean energy dissipation(p=0.002)and contribution to total energy dissipation(p<0.001)during the landing stance.Meanwhile,there were no differences in hip joint contribution to total energy dissipation(p=0.523)and lower limb total energy dissipation(p=0.127).A deeper understanding of each joint’s energy dissipation contribution ratio between UPT and PT during landing can provide clues that reveal the biomechanical mechanism of PT athletes landing.Further study should choose a larger sample size to more comprehensively reveal the energy dissipation strategy of PT during landing. | Datao Xu Zhenghui Lu Siqin Shen Gusztáv Fekete Ukadike CUgbolue Yaodong Gu | 2021 | Molecular & Cellular Biomechanics2021，18，2： | 1 |

| 4 | Temporoparietal Fascia Flaps for Surgical Treatment of Cartilage Exposure After the First-Stage Microtia Reconstruction显示文摘Significant improvements have been achieved in microtia reconstruction using an autogenous costal cartilage framework.However,complications such as skin necrosis and cartilage exposure often destroy the final contour of the reconstructed auricle.Local fascia flaps are commonly used in salvage surgery because of their reliability and satisfactory results.Here,we report the case of a 26-year-old woman with multiple skin necroses and cartilage exposure on day 21 after the first-stage microtia reconstruction.The exposure area was covered by a temporoparietal fascia flap as a single-stage procedure.The most essential subunits survived,and the esthetic concours were harmonious and natural at 12 months postoperatively.Temporoparietal fascia flaps are recommended as the surgical treatment for multiple skin necroses and cartilage exposure in microtia reconstruction.The axial-pattern temporoparietal fascia flap is reliable for salvage auricular reconstruction and ensures satisfactory results at long-term follow-up. | Zhicheng XU Ruhong ZHANG Qun ZHANG Feng XU Datao LI Yiyuan LI Xia CHEN | 2021 | Chinese Journal Of Plastic and Reconstructive Surgery2021，3，2： | 0 |
| 5 | Comparison of Biomechanical Characteristics during the Second Landing Phase in Female Latin Dancers:Evaluation of the Bounce and Side Chasse Step显示文摘Research on dance lower extremity joint motion has been limited.Thus,the purpose of this study was to investigate the lower limb biomechanics differences between the side chasse step(SCS)and the bounce step(BS)of the second landing phase in Jive.Thirteen female recreational Latin dancers(Age:22±2.5 years;Height:1.65±0.05 m;Weight:50±4.5 kg;Dance experience:4±2 years)were involved in the experiment.The same music was used throughout the data collection period.We intended to determine whether these two steps generate different kinematic and kinetic data.The ankle,hip,and knee joint angle,moment,velocity,and ground reaction force were calculated for each step.Results demonstrated that the lower limb biomechanics of the two different steps showed significant differences.As a result,strengthening the lower limb muscles(gastrocnemius,Tibialis muscle,and quadriceps)is significantly important to balance the joint strength and prevent foot injury.According to the training time reasonably increasing the heel height should be recognized as important.The current study could provide new insights into reducing lower extremity injuries and improving dance performance. | Fengfeng Li Huiyu Zhou Datao Xu Julien S.Baker Yaodong Gu | 2022 | Molecular & Cellular Biomechanics2022，19，3： | 0 |
| 6 | Effects of Forefoot Shoe on Knee and Ankle Loading during Running in Male Recreational Runners显示文摘Objectives:Although overuse running injury risks for the ankle and knee are high,the effect of different shoe designs on Achilles tendon force(ATF)and Patellofemoral joint contact force(PTF)loading rates are unclear.Therefore,the primary objective of this study was to compare the ATF at the ankle and the PTF and Patellofemoral joint stress force(PP)at the knee using different running shoe designs(forefoot shoes vs.normal shoes).Methods:Fourteen healthy recreational male runners were recruited to run over a force plate under two shoe conditions(forefoot shoes vs.normal shoes).Sagittal plane ankle and knee kinematics and ground reaction forces were simultaneously recorded.Ankle joint mechanics(ankle joint angle,velocity,moment and power)and the ATF were calculated.Knee joint mechanics(knee joint angle velocity,moment and power)and the PTF and PP were also calculated.Results:No significant differences were observed in the PTF,ankle plantarflexion angle,ankle dorsiflexion power,peak vertical active force,contact time and PTF between the two shoe conditions.Compared to wearing normal shoes,wearing the forefoot shoes demonstrated that the ankle dorsiflexion angle,knee flexion velocity,ankle dorsiflexion moment extension,knee extension moment,knee extension power,knee flexion power and the peak patellofemoral contact stress were significantly reduced.However,the ankle dorsiflexion velocity,ankle plantarflexion velocity,ankle plantarflexion moment and Achilles tendons force increased significantly.Conclusions:These findings suggest that wearing forefoot shoes significantly decreases the patellofemoral joint stress by reducing the moment of knee extension,however the shoes increased the ankle plantarflexion moment and ATF force.The forefoot shoes effectively reduced the load on the patellofemoral joint during the stance phase of running.However,it is not recommended for new and novice runners and patients with Achilles tendon injuries to wear forefoot shoes. | Jingying Lu Datao Xu Wenjing Quan Julien SBaker Yaodong Gu | 2022 | Molecular & Cellular Biomechanics2022，19，2： | 0 |
| 7 | Boosting the Energy Migration Upconversion through Inter-Shell Energy Transfer in Tb^(3+)-Doped Sandwich Structured Nanocrystals显示文摘It remained challenging to fabricate Tb^(3+)-doped lanthanide nanocrystals(NCs)to simultaneously acquire strong energy migration upconversion(EMU)emissions of Tb^(3+)while suppressing the Tm3+UV upconversion emissions that cause background biofluorescence issues in bioapplications based on Tb^(3+)-doped EMU NCs.Herein,we report a novel sandwich structured core@shell@shell scheme for the design of EMU NCs,for example,NaLuF4∶Yb/Gd@NaGdF4∶Tm@NaLuF4∶Tb NCs,wherein Yb^(3+),Tm^(3+),and Tb^(3+)are incorporated separately into the inner core,middle shell,and outer shell,respectively.We found that in the sandwich structured NCs,the effective inter-shell energy transfer from Gd^(3+)in the middle shell to Tb^(3+)in the outer shell accelerated the Yb^(3+)-Tm^(3+)five-photon upconversion and the subsequent Tm^(3+)to Gd^(3+)energy transfer processes,which could eventually lead to almost complete inhibition of Tm^(3+)UV upconversion emissions,concurrent with the strong EMU emissions of Tb^(3+).Our findings might stimulate new concepts for manipulating upconversion emissions of lanthanide NCs. | Dan Xu Jin Xu Xiaoying Shang Shaohua Yu Wei Zheng Datao Tu Renfu Li Xueyuan Chen | 2022 | CCS Chemistry2022，4，6： | 0 |
