The importance of gait assessment in the rehabilitation of cancer patients is gradually being recognized. However, quantitative analysis of balance ability in cancer patients is still limited. A total of 102 cancer patients meeting the inclusion criteria were recruited from Hefei Cancer Hospital, Chinese Academy of Sciences. Their balance ability was evaluated using the Berg Balance Scale (BBS). Gait data were collected by an electronic walkway and an IMU sensor system, including spatial-temporal and kinematic gait features such as step length, cadence, support time, and range of motion. Recursive feature elimination was used for feature selection. Ridge, Elastic Net, SVR, RF, and AdaBoost models were used to predict balance ability scores. Five-fold cross-validation was used to evaluate the performance of these models. Results show that the SVR model achieves the best performance with fifteen features (RMSE=3.22, R ²=0.91), followed by Ridge (RMSE=3.63, R ²=0.89). A method for evaluating balance ability based on gait features is proposed, providing a quantitative tool for personalized rehabilitation interventions in cancer patients.

Prostate cancer (PCa) is the most common urological malignancy in men worldwide, and its incidence is increasing annually. Radiotherapy is one of the main treatment methods for PCa. However, some patients still have recurrence, local progression, and even distant metastasis after receiving radical radiotherapy. As an emerging tumor treatment strategy, immunotherapy has made great progress in the treatment of various solid tumors. Owing to the inherent immune escape mechanism of PCa, the efficacy of immunotherapy is unsatisfactory. Therefore, new combined strategies must be explored to improve the efficacy of immunotherapy for PCa. With the in-depth study of the tumor immune microenvironment, the immunomodulatory effect of radiotherapy has gradually attracted attention. Researchers found that the immunomodulatory effect of radiotherapy depends on the dose. Low-dose radiotherapy can enhance tumor immunogenicity by remodeling the tumor microenvironment, whereas high-dose radiotherapy can further activate the innate immune signaling pathway by directly inducing the immunogenic necrosis of tumor cells. Therefore, the synergistic strategy of radiotherapy and immunotherapy has become a research hotspot. This work aims to review the regulatory effect of radiotherapy on PCa antitumor immunity, clarify the latest progress and potential clinical value of radiotherapy combined with immunotherapy, and provide a theoretical basis and new research directions for optimizing the combination immunotherapy strategies for prostate cancer.

Objective To investigate the genetic characteristics and recombination of human-infected sapoviruses(SaVs)worldwide using bioinformatics.Methods The complete genome sequences of SaVs were downloaded from the National Center for Biotechnology Information(NCBI)while high-quality complete genomes were retained for analysis.Molecular phylogenetic trees of SaVs were constructed to analyze their genetic characteristics,followed by recombination analysis of human-infected SaV strains genetype Ⅰ,Ⅱ,Ⅳ,and V(G Ⅰ,G Ⅱ,GⅣ,and GⅤ)with recombination analysis software.Results SaVs exhibited substantial genetic diversity worldwide and infected a wide range of hosts.Human-associated SaVs included G Ⅰ,G Ⅱ,GⅣ,and GⅤ,with GⅤ shared between human and swine hosts.Genetype recombination analysis of SaVs revealed a high frequency of recombination in SaV G Ⅱ strains that involved diverse hosts in the field of SaV G V strains.Recombination breakpoints of the virus were concentrated in the major viral proteins 1(VP1)and minor viral proteins 2(VP2).Conclusion Based on systematic analysis of the genetic characteristics of human-infected SaVs,the genotype distribution and prevalence of SaVs are investigated,the recombination patterns of SaV revealed,and its genetic dynamics highlighted.These findings can offer insights into epidemiological trends of viruses and help devise effective prevention and control strategies.

Objective:To investigate the effects of the taurochenodeoxycholic acid(TCDCA)on cartilage degeneration in tem-poromandibular joint osteoarthritis(TMJ OA).Methods:36 female SD rats aged 6 weeks were randomly divided into 3 groups:con-trol group(CON),unilateral anterior crossbite group(UAC),UAC plus TCDCA injection group(UAC+TCDCA).UAC model was es-tablished in all rats in UAC and UAC+TCDCA groups.Samples were collected at 8 and 12 weeks(control group,UAC group,UAC+TCDCA group)after set up of the experiment(n=6),and TMJ morphological examination was performed.The expression of CYP7A1,BAAT and TGR5 in the tissue and cells was examined by immunohistochimical staining.Results:(1)Compared with the CON group of the same age,the cells in the condylar cartilage were disordered,the cartilage matrix was reduced and thinner in UAC group.Compared with UAC group of the same age,cell arrangement,cell number,cartilage matrix and cartilage thickness were im-proved in UAC+TCDCA group(P＜0.05).(2)Compared with the CON group of the same age,the positive cells for TCDCA-specific receptor TGR5 and the key enzymes CYP7A1 and BAAT were mainly distributed in the anterior hypertrophic layer and hypertrophic layer at each time point.The number of positive cells in the UAC group was significantly reduced compared with the CON group.Conclusion:TCDCA has obvious therapeutic effects on the degeneration in TMJ OA.

Oral squamous cell carcinoma (OSCC) is a common cancer that develops from oral epithelial cells, it has a high incidence, mortality and teratogenic rate, which poses a serious threat to people′s life and health.The Hippo signaling pathway plays a key role in tumorigenesis, regulation of stem cell homeostasis, tissue regeneration, and organ size control. In OSCC, activation of Hippo signaling pathway can inhibit malignant biological behavior, epithelial mesenchymal transformation and distant metastasis of tumors, and improve the survival rate of patients. Considering the importance of the Hippo signaling pathway in the development of cancer, this paper summarized the composition and regulatory mechanism of Hippo pathway, elaborated the role of Hippo signaling pathway in the occurrence and development of OSCC.At the same time, make a simple generalization about the potential therapeutic approaches and strategies to reduce the risk of drug resistance for OSCC patients targeting this pathway.

Objective:To summarize the clinical nursing experience of oxygenation (ECMO) adjuvant therapy in children with acute respiratory distress syndrome (ARDS) caused by severe adenovirus pneumonia.Method:The clinical data of 20 children with severe adenovirus pneumonia complicated with ARDS who received ECMO in our hospital from April 2017 to May 2019, including general conditions, pre-treatment, complications and prognosis, were retrospectively analyzed.Results:The primary disease of 20 patients was severe adenovirus pneumonia, and the average duration of ECMO treatment was [247.50(152.00,296.75)] hours. After treatment, 12 (12/20) patients successfully escaped from ECMO, 11 (11/20) patients died, and 9 (9/20) died. Complications occurred in 17 (17/20) patients with ECMO treatment. After discharge from the hospital for six months to two years, 9 patients with good quality of life, social function, normal mental development, 2 patients with ischemia and hypoxia brain damage, in the hospital or family continued rehabilitation exercise.Conclusions:Children with severe adenovirus pneumonia combined with ARDS are critically ill. When other treatments are ineffective, ECMO treatment can provide cardiopulmonary support for children with reversible cardiopulmonary failure, but the complications are numerous and serious. Prevention and reduction of related complications are the key to the success of ECMO.

Objective To observe the implementation of national food safety standard for “Iodine Concentration in Edible Salt”(GB 26878-2011) and its effectiveness on iodine nutritional status of key populations. Methods Information of iodine concentration in edible iodized salt of various provinces (autonomous regions and municipalities, including Xinjiang Production and Construction Corps) was collected using Baidu Searching Engine through the establishment of key words. Sal t samples were collected in Tianjin City and Aksu Region of Xinjiang , and the salt iodine concentration in both places was 30 mg/kg. In Tianjin, Hongqiao, Tanggu and Hangu, Beichen were selected as representatives of the downtown areas, the coastal areas and the suburbs, respectively and counties of Baodi and Ji were iodine deficiency areas in history. Sampling work was carried out from August 2012 to March 2013 in Tianjin. In Aksu, Yatuoer Township and Charqi Town in Baicheng County, Aotebeixi and Aketuohai Townships in Wushen County were chosen as iodine deficiency areas, and the survey was carried out from January to September 2013 . Random urine samples of school-age children ( 8 - 10 years old ) , pregnant women and lactating women were collected; urinary iodine was measured following the Method for Determination of Iodine in Urine by As3+-Ce4+ Catalytic Spectrophotometry(WS/T 107-2006) and iodine in edible iodized salt was measured following the General Test Method in Salt Industry Determination of Iodideion ( GB/T 13025 . 7-1999 ) . Results Fourteen of the provinces(autonomous regions and municipalities, including the Corps of Xinjiang) chose 25 mg/kg as their iodine concentration in edible iodized salt and 13 provinces chose 30 mg/kg. Besides, there were another 5 provinces providing 30 mg/kg particularly for pregnant women and lactating women while 25 mg/kg for other populations. In Tianjin, the medians of iodine concentration in edible iodized salt were ranged from 24.4 - 32.1 mg/kg in retail stores and 26.4 mg/kg at households. The household coverage rate of iodized salt and the proportion of households using adequately iodized salt were 78.5%(168/214) and 62.6%(134/214), respectively. The median ranges of urinary iodine were 178.2 - 183.9 μg/L in school children, 124.3 - 130.9 μg/L in pregnant women and 72.7 - 109.5 μg/L in lactating women. In Aksu, the medians of iodine concentration in edible iodized salt were 27.1 and 26.5 mg/kg in retail stores and households, respectively. The household coverage rate of iodized salt and the proportion of households using adequately iodized salt were 100.0% (363/363) and 98.9%(359/363), respectively. The median ranges of urinary iodine were 174.8 - 293.0, 154.9 - 230.0 and 135.8 - 239.3 μg/L among school children, pregnant women and lactating women, respectively. The median of iodine concentration in a special edible iodized salt sample reached 49.1 mg/kg, and qualified rate was 0(0/11) in Aksu. Conclusions All provinces , municipalities and autonomous regions ( including the Corps of Xingjiang ) in China have adjusted the iodine content in edible iodized salt in accordance with GB 26878-2011. However, in Tianjin the household iodine concentration in edible salt is lower than the local standards; the household coverage rate of iodized salt and the proportion of households using adequately iodized salt are lower than the national standards; pregnant women and lactating women are at risk of mild iodine deficiency.
