OBJECTIVETo establish a perceived fatigue evaluating model during simulated load carriage that is based on objective variables through analyzing the characteristics and trends of shoulder force, shoulder pressure, waist pressure, back pressure, and perceived fatigue, and to provide an analytical technique for research on load carriage.

METHODSA 50-min simulated walking (at a speed of 5 km/h and a slope of 0%) experiment including 14 healthy male adults was conducted under four levels of backpack payloads (25, 29, 34, 37 kg). Shoulder force and trunk pressure were sampled simultaneously and analyzed with time- and frequency- domain methods. Multivariable linear regression was used to build a perceived fatigue evaluating model during load carriage.

RESULTSThe perceived fatigue evaluating model based on shoulder force, trunk pressure distribution ratio, load, and body mass index (BMI) was established. Its adjusted determination coefficient (aR2) was 0.709 and the absolute percentage error (APE) at the end of the experiment was less than 20%. The goodness of fit of the model based on frequency-domain independent variables was much higher compared with the model based on time-domain independent variables. The addition of BMI that represents the individual differences to the model obviously improved the goodness of fit.

CONCLUSIONThe perceived fatigue evaluating model established in this study does not rely on the physiological changes of individuals, and thus can be used to establish an evaluation system for human load carriage with dummy as a substitution for human in experiments and to provide a scientific basis for efficient human load carriage.

Objective By observing the clinical efficacy of acupuncture plusBu Shen Jie Yu Qing Xin decoction (herbal decoction for tonifying kidney, anti-depression and clearing heart fire) in treating perimenopausal depression, to discuss about the effect of acupuncture plus medication on Hamilton Depression Scale (HAMD), Self-rating Depression Scale (SDS) and hypothalamic-pituitary-ovarian (H-P-O) axis in perimenopausal depression patients.Method By following a completely randomized design, sixty perimenopausal depression patients were divided into a Chinese medication group (Bu Shen Jie Yu Qing Xin decoction) with 30 cases, and an acupuncture-medication group (acupuncture plusBu Shen Jie Yu Qing Xin decoction) with 30 cases, to receive 12-week treatment in total. The HAMD and SDS were estimated prior to the treatment and in the 4th, 8th and 12th weeks; the serum follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), testosterone (T), prolactin (PRL), and progesterone (P) contents were detected before and after the treatment.Result Acupuncture plus medication and Chinese medication alone were both effective in treating perimenopausal depression, and the therapeutic efficacy of acupuncture plus medication was superior to that of Chinese medication alone (P<0.05). In the acupuncture-medication group, the HAMD score dropped significantly in the 4th, 8th and 12th weeks compared to that before the treatment, and the score dropped significantly in the 8th and 12th weeks compared to that before the treatment in the Chinese medication group (P<0.01). The HAMD score in the acupuncture-medication group was significantly lower than that in the Chinese medication group in the 4th, 8th and 12th weeks (P<0.01). After the treatment, the items including anxiety, insight, sleep, and despair were significantly changed in the Chinese medication group (P<0.05); 7 items were significantly changed in the acupuncture-medication group (P<0.05). The scores of anxiety, insight, sleep, diurnal-nocturnal, obstruction, and body weight in the acupuncture-medication group were significantly superior to those in the Chinese medication group (P<0.05). The SDS score dropped significantly in the 4th, 8th and 12th weeks in the acupuncture-medication group, and in the 8th and 12th weeks in the Chinese medication group (P<0.01,P<0.05); in the 4th and 8th weeks, the SDS score in the acupuncture-medication group was significantly lower than that in the Chinese medication group (P<0.05), while the between-group difference was statistically insignificant in the 12th week (P>0.05). After 12-week treatment, the contents of FSH and LH declined significantly in both groups (P<0.01, P<0.05), and the contents of E2 and T increased significantly in the acupuncture-medication group (P<0.01,P<0.05). The decrease of FSH and LH, and the increase of E2 were more significant in the acupuncture-medication group (P<0.05,P<0.01).Conclusion Acupuncture plus medication can improve the symptoms of perimenopausal depression, and it takes a faster action than Chinese medication alone. Acupuncture plus medication can mitigate 7 items in HAMD, while Chinese medication can improve anxiety, insight, sleep and despair. Acupuncture plus medication can produce a more significant efficacy in improving anxiety, insight, sleep, diurnal-nocturnal, obstruction, and body weight compared to Chinese medication. For perimenopausal depression, acupuncture plus medication can correct the endocrine disorder and improve depression state by down-regulating the levels of FSH and LH, and up-regulating the contents of E2 and T to improve the function of H-P-O axis.

Objective To investigate the nutritional status of the pupils with cerebral palsy and the factors related with nutrition. Methods The height and weight of 139 cerebral palsy pupil (6~18 years old) were measured. The rate of stunting, wasting, overweight and obesity were calculated, and compared with the norm, and among the subjects with different cerebral palsy type, grade of Gross Motor Function Classification System (GMFCS), famiy background (urban or rural), age, etc. Results The rate of stunting and wasting was more than the norm, and the obesity was less. The rate of stunting negatively correlated with the grade of GMFCS. The rate of wasting negatively correlated with the age.

Objective:Anterior cruciate ligament injury is the most common type of knee joint ligament injury.Anterior cruciate ligament reconstruction has a high failure rate,with bone tunnel abnormalities as the most significant factor in these failures.Digital orthopedic technology can effectively develop implementation plans for the revision,thus increasing the success rate.This study aims to develop a surgical plan for anterior cruciate ligament revision by employing multiplanar reconstruction(MPR)for measuring bone tunnel position and diameter,and simulating bone tunnel creation via 3D printing preoperatively. Methods:A total of 12 patients who underwent anterior cruciate ligament revision at the Third Xiangya Hospital of Central South University between 2014 and 2021 were retrospectively studied.The data included patient demographics,preoperative formulated knee joint 3D printing models,and preoperative knee CT scans.The study measured the bone tunnel's diameter and position to guide the establishment of revision bone tunnels during surgery,reassessed the postoperative bone tunnels,and evaluated knee joint functional scores[including International Knee Documentation Committee Knee Evaluation Form(IKDC)score,Lysholm score,and Tegner exercise level score]. Results:Preoperative measurements revealed suboptimal femoral tunnels positions in 4 patients and tibial tunnels positions in 2 patients.MPR and 3D printing technology were used to guide the establishment of a new bone canal during surgery,and postoperative measurements were satisfactory for all patients.Preoperative measurements demonstrated the interclass correlation coefficient for femoral tunnels and tibial tunnels diameters were 0.843(P<0.05)and 0.889(P<0.001),respectively.Meanwhile,the intraclass correlation coefficient were 0.811(P<0.05)and 0.784(P<0.05),respectively.The intraoperative diameter of femoral and tibial tunnels showed excellent correlation with postoperative CT measurements,with intraclass correlation coefficient values of 0.995(P<0.001)and 0.987(P<0.001),respectively.All bone tunnel positions were within the normal range.At the final follow-up,knee joint function scores in all 12 patients improved significantly compared to pre-surgery(P<0.001),and the reoperation rate was zero. Conclusion:MPR and 3D printing technology can accurately measure the parameters of reconstructed anterior cruciate ligament bone tunnels.Personalized revision plans for patients with reconstruction failure enhances the success rate of revision surgery and improves patient prognosis.

Genetic studies have revealed a critical role of Distal-homeobox (Dlx) genes in bone formation, and our previous study showed that Dlx2 overexpressing in neural crest cells leads to profound abnormalities of the craniofacial tissues. The aim of this study was to investigate the role and the underlying molecular mechanisms of Dlx2 in osteogenic differentiation of mouse bone marrow stromal cells (BMSCs) and pre-osteoblast MC3T3-E1 cells. Initially, we observed upregulation of Dlx2 during the early osteogenesis in BMSCs and MC3T3-E1 cells. Moreover, Dlx2 overexpression enhanced alkaline phosphatase (ALP) activity and extracellular matrix mineralization in BMSCs and MC3T3-E1 cell line. In addition, micro-CT of implanted tissues in nude mice confirmed that Dlx2 overexpression in BMSCs promoted bone formation in vivo. Unexpectedly, Dlx2 overexpression had little impact on the expression level of the pivotal osteogenic transcription factors Runx2, Dlx5, Msx2, and Osterix, but led to upregulation of Alp and Osteocalcin (OCN), both of which play critical roles in promoting osteoblast maturation. Importantly, luciferase analysis showed that Dlx2 overexpression stimulated both OCN and Alp promoter activity. Through chromatin-immunoprecipitation assay and site-directed mutagenesis analysis, we provide molecular evidence that Dlx2 transactivates OCN and Alp expression by directly binding to the Dlx2-response cis-acting elements in the promoter of the two genes. Based on these findings, we demonstrate that Dlx2 overexpression enhances osteogenic differentiation in vitro and accelerates bone formation in vivo via direct upregulation of the OCN and Alp gene, suggesting that Dlx2 plays a crucial role in osteogenic differentiation and bone formation.
