Osteoarthritis (OA) is the most common degenerative joint disease. Its pathological process is related to inflammatory response, chondrocyte apoptosis, and cartilage degeneration. Hippo-yes-associate protein(YAP) signaling pathway plays an important role in mediating organ size and tissue homeostasis. In recent years, the key effector protein YAP in the Hippo-YAP pathway has become a research hotspot in osteoarthritis. This article introduces the activation process of Hippo-YAP signaling pathway and the biological role of YAP. It reviews the progress of YAP in regulating osteoarthritis by influencing the proliferation and differentiation of mesenchymal stem cells and the proliferation, differentiation, and apoptosis of articular chondrocytes. It analyzed the problems encountered in YAP research in OA, introduces the research potential of YAP in other orthopedic diseases, and provides new ideas for subsequent research in Osteoarthritis.

Objective To compare the fidelity of chronic obstructive pulmonary disease(COPD)models established using two methods:exposure to cigarette smoke(CS)and exposure to motor vehicle exhaust(MVE)in rats.Methods Twenty-four male SD rats were randomly divided into control,CS-exposed(CS),and MVE-exposed(MVE)groups,with 8 rats per group.Rats in CS and MVE groups were exposed to CS or MVE,respectively,to induce COPD models.After COPD model established,lung function of each group was assessed.Bronchoalveolar lavage fluid(BALF)was collected to measure inflammatory cell counts,levels of inflammatory cytokines interleukin-6(IL-6)and tumor necrosis factor(TNF)-α,and expression levels of mucin 5AC(MUC5AC).Lung tissue sections were stained with hematoxylin and eosin(HE)to observe pulmonary tissue and airway pathological changes.Periodic acid-Schiff(PAS)staining was used to detect goblet cell hyperplasia in airways.Results Compared with control group,rats in CS and MVE groups showed significantly increased inspiratory resistance(RI),total lung capacity(TLC),and lung static compliance(Cchord)(P<0.05),while expiratory flow parameters FEV50/FVC were significantly decreased(P<0.05).Compared with MVE group,rats in CS group had significantly higher RI,TLC,and Cchord(P<0.05),and lower FEV50/FVC(P<0.05).HE staining of lung tissues showed that mean linear intercept(MLI)was significantly higher in both CS and MVE groups compared with control group(P<0.05),with CS group having higher MLI than MVE group(P<0.05).BALF analysis revealed that white blood cells,neutrophils,macrophages,lymphocytes,IL-6,and TNF-α levels were significantly higher in both CS and MVE groups compared with control group(P<0.05),and inflammatory cell counts,IL-6,and TNF-α levels were higher in CS group compared with MVE group(P<0.05).PAS staining of lung tissues indicated that goblet cells in large airways were significantly increased in both CS and MVE groups compared with control group(P<0.05),with CS group showing higher goblet cell counts than MVE group(P<0.05).Expression levels of MUC5AC in BALF were significantly higher in both CS and MVE groups compared with control group(P<0.05),with CS group having significantly higher MUC5AC levels than MVE group(P<0.05).Conclusions Exposure to CS or MVE can establish a rat model of COPD,with CS exposure better mimicking characteristics of acute exacerbation of COPD compared to MVE exposure.

OBJECTIVE: To observe the clinical efficacy of transcutaneous electrical acupoint stimulation (TEAS) combined with warm acupuncture in treating breast cancer associated with upper limb lymphedema (BCRL). METHODS: This was a retrospective cohort study using a paired control design. Fifty-two BCRL patients were assigned to the control group (27 cases) and the treatment group (25 cases). The patients in the control group were treated with lymphedema comprehensive detumescence treatment (CDT) for 4 weeks, including systematic therapy composed of manual lymphatic drainage, compression bandage, skincare, and functional exercise. The patients in the treatment group were treated with TEAS combined with warm acupuncture based on the control group methods. Each treatment lasted for 30 min and was applied twice a week for 4 weeks. The arm circumference (AC) of different positions of the affected limb and the degree of swelling of the affected limb were evaluated before the first treatment and after the last treatment. The clinical efficacy was evaluated according to the degree of edema before and after treatment. All adverse events during treatment were recorded. RESULTS: The patients' AC and the swelling feeling of the affected limb in the treatment group and the control group were both reduced compared with those before treatment. Compared with the control group, AC of the wrist joint transverse stria, the midpoint between the wrist joint transverse stria and the elbow joint transverse stria in the treatment group were significantly reduced (P<0.05). The decrease in AC diameter at the midpoint between the elbow joint transverse stria and the axillary transverse stria was the most significant (P<0.01). The swelling degree of the affected limbs in the treatment group was significantly lower than before treatment, and was significantly lower compared with the control group after treatment (P<0.01). The total effective rate was 72% in the treatment group, significantly higher than that in the control group (55.56%, P<0.05). No serious adverse events occured in either group. CONCLUSIONS TEAS combined with warm acupuncture can effectively reduce AC and swelling feeling of the affected limb in patients with BCRL. The effect is better than that of CDT therapy alone.

Objective: This study aimed to explore the prognostic value of the revised international prognostic scoring system (IPSS-R) and the WHO prognostic scoring system (WPSS) in patients with myelodysplastic syndrome (MDS) undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods: The clinical data of 184 patients with MDS who received allo-HSCT from July 2016 to June 2019 were retrospectively analyzed. IPSS-R and WPSS were performed at diagnosis and before transplantation. The prognostic values of IPSS-R and WPSS and potential risk factors were explored. Results: With a median follow-up of 21.9 (0.5-47.5) months, the two-year overall survival (OS) and progression-free survival (PFS) rates were (75.1±3.4)% and (71.6±3.6)% , respectively. The two-year cumulative relapse rate and nonrelapse mortality rate were (11.9±0.1)% and (16.5±0.1)% , respectively. There were no significant differences in OS and PFS between the IPSS-R ≤3.5 and >3.5 groups at diagnosis (P=0.409; P=0.724). No significant differences in OS and PFS between the WPSS ≤2 and >2 groups (P=0.426; P=0.726) were observed as well. When the patients were reevaluated before transplantation, the OS and PFS of the IPSS-R ≤3.5 group were significantly better than >3.5 group [OS: (88.6±4.1)% vs (65.8±5.3)% , P=0.003; PFS: (87.6±4.2)% vs (60.5±5.8)% , P=0.002]. However, there were no significant differences in OS and PFS among the WPSS ≤2 and >2 groups (P=0.584; P=0.565). In addition, the OS and PFS of the improved group based on IPSS-R were significantly better than those of the unimproved group before transplantation [OS: (83.8±4.6)% vs (69.3±5.8)% , P=0.027; PFS: (82.8±4.4)% vs. (64.0±7.2)% , P=0.006]. Multivariate analysis indicated that a pretransplant IPSS-R of >3.5 (P=0.021, HR=2.510, 95% CI 1.151-5.476) and TP53 mutation (P=0.047, HR=2.460, 95% CI 1.014-5.971) were independent risk factors for OS, whereas a pretransplant IPSS-R of >3.5 (P=0.017, HR=2.457, 95% CI 1.175-5.141) and pretransplant cytogenetic poor and very poor (P=0.008, HR=2.765, 95% CI 1.305-5.856) were independent risk factors for PFS. Conclusion: A pretransplantation evaluation of IPSS-R could help determine the prognosis of patients with MDS undergoing allo-HSCT. In addition, patients with improved IPSS-R scores before undergoing allo-HSCT had a better prognosis.

Objective Coronavirus disease 2019 (COVID-19) and tuberculosis (TB) are major public health and social issues worldwide. The long-term follow-up of COVID-19 with pulmonary TB (PTB) survivors after discharge is unclear. This study aimed to comprehensively describe clinical outcomes, including sequela and recurrence at 3, 12, and 24 months after discharge, among COVID-19 with PTB survivors. Methods From January 22, 2020 to May 6, 2022, with a follow-up by August 26, 2022, a prospective, multicenter follow-up study was conducted on COVID-19 with PTB survivors after discharge in 13hospitals from four provinces in China. Clinical outcomes, including sequela, recurrence of COVID-19, and PTB survivors, were collected via telephone and face-to-face interviews at 3, 12, and 24 months after discharge. Results Thirty-two COVID-19 with PTB survivors were included. The median age was 52 (45, 59) years, and 23 (71.9％) were men. Among them, nearly two-thirds (62.5％) of the survivors were moderate, three (9.4％) were severe, and more than half (59.4％) had at least one comorbidity (PTB excluded). The proportion of COVID-19 survivors with at least one sequela symptom decreased from 40.6％ at 3 months to 15.8％ at 24 months, with anxiety having a higher proportion over a follow-up. Cough and amnesia recovered at the 12-month follow-up, while anxiety, fatigue, and trouble sleeping remained after 24 months. Additionally, one (3.1％) case presented two recurrences of PTB and no re-positive COVID-19 during the follow-up period. Conclusion The proportion of long symptoms in COVID-19 with PTB survivors decreased over time, while nearly one in six still experience persistent symptoms with a higher proportion of anxiety. The recurrence of PTB and the psychological support of COVID-19 with PTB after discharge require more attention.

Objective: To evaluate the efficiency of internal carotid artery (ICA) embolization technology in endoscopic salvage surgery for recurrent nasopharyngeal carcinoma (rNPC) invading the ICA. Methods: From January 2016 to March 2021, 83 patients with rNPC who invaded the ICA and underwent endoscopic extended nasopharyngectomy were retrospectively collected from the Eye & ENT Hospital in Fudan University, including 60 males and 23 females. The age of the patients ranged from 27 to 77 years. The standard of ICA invasion was that the distance from the lesion to the ICA on enhanced MRI was ≤ 1.8 mm. The clinical characteristics, ICA management strategy and survival prognosis of patients were analyzed, and the effectiveness of ICA embolization was evaluated. Kaplan-Meier method was used to calculate the survival rate and Log-rank test was used to compare the difference. Results: In 83 patients with rNPC, there were 13 patients with rT2, 38 patients with rT3, 32 patients with rT4, and 16 patients had lymph node metastasis. A total of 37 patients (44.6%) underwent ICA coil embolization before surgery, of which 2 cases underwent external carotid-middle cerebral artery artery bypass grafting and ICA embolization due to positive balloon occlusion test (BOT). Patients with positive surgical margin accounted for 24.1% (20/83). Among them, patients with rT4 and patients without ICA embolization had a higher positive rate of surgical margin (P value was 0.001, 0.043, respectively). The 3-year overall survival (OS) and progression free survival (PFS) rate of all patients was 46.5% and 26.7%, respectively. In addition, the 3-year OS and PFS of patients with ICA embolization was significantly higher than those without ICA embolization, respectively (69.1% vs 27.8%, P=0.003; 33.9% vs 18.9%, P=0.018). Only 2 patients (2/37, 5.4%) had cerebral infarction complications after coil embolization of the affected ICA due to negative BOT. Conclusion: Preoperative ICA embolization can be used to treat patients with rNPC invading the ICA, improve the total removal rate and survival rate of patients, which is an effective salvage treatment.

Objective To investigate the prevalence of Spirometra mansoni infections in hosts in Jiangsu Province, so as to provide the scientific basis for the management of sparganosis mansoni. Methods From 2018 to 2019, nine counties (cities, districts) were randomly selected from Jiangsu Province as the survey sites, and 100 healthy individuals were randomly selected to perform the serological test of S. mansoni infections and the detection of S. mansoni eggs. The procercoids were detected in the intermediate host Cyclops, and the S. mansoni eggs were identified in the stool samples of the definitive hosts cats and dogs. Results The prevalence of S. mansoni human infections was 0 (0/900) in the 9 survey sites of Jiangsu Province, and the sero-prevalence of the specific IgG antibody against S. mansoni was 1.22% (11/900). The positive rate of procercoids was 0.33% (3/900) in Cyclops. In addition, the S. mansoni egg-positive rate was 1.48% (2/135) in cats and dogs. Conclusions Sparganosis mansoni is prevalent in Jiangsu Province. Health education pertaining to the damages of sparganosis mansoni and the route of S. mansoni infections should be improved.

In this study, a high performance thin-layer chromatography/single quadrupole mass spectrometry QDa (HPTLC-QDa) method for robust authentication of Ganoderma lucidum, a popular and valuable herbal medicine, has been developed. This method is simple and practical, which allows direct generation of characteristic mass spectra from the HPTLC plates automatically with the application of in situ solvent desorption interface. The HPTLC silica gel plates were developed with toluene-ethyl formate-formic acid (5 : 5 : 0.2, V/V) and all bands were transferred to QDa system directly in situ using 80% methanol with 0.1% formic acid as desorption solvent. The acquired HPTLC-QDa spectra showed that luminous yellow band b3, containing ganoderic acid B/G/H and ganodeneric acid B, the major active components of Ganoderma, could be found only in G. lucidum and G. lucidum (Antler-shaped), but not in G. sinense and G. applanatum. Moreover, bands b13 and b14 with m/z 475/477 and m/z 475/491/495, respectively, could be detected in G. lucidum (Antler-shaped), but not in G. lucidum, thus allowing simple and robust authentication of G. lucidum with confused species. This method is proved to be simple, practical and reproducible, which can be extended to analyze other herbal medicines.

Objective:To analyze the categories and its relations of recreational physical activities and rehabilitation exercise for adult with disabilities based on the theory and method of International Classification of Functioning, Disability and Health (ICF). Methods:An evidence-based scoping review had been implemented. We had developed the framework and coding approaches for recreational physical activities, rehabilitation exercise and functional improvement for the adults with disabilities based on evidence-based literature review. The literature related to recreational physical activities and rehabilitation exercise of adult with disabilities was searched by subject retrieval method. The retrieval database in Chinese included CNKI and Wanfang database, and the retrieval database in English included PubMed and Web of Science. The retrieval time was from establishment to July 31, 2020. The authors, countries, published time, published journals, research objectives, object of the study and their ages, data collection tool, and the key findings were extracted. Results:A total of 2476 literatures were returned, and 18 of them were enrolled, which were published in 14 countries, and most were published in journals on topics related to medicine, public health, exercise and people with disabilities. They were mainly published from 2010 to 2020, and mainly used questionnaire survey, measurement and interviewing method. There were three typical recreational physical activities: physical fitness activities, skills activities and sports activities, mainly including Taiji Quan, wheelchair basketball, leisure outdoor activities, community recreational sports activities and rehabilitation exercises, etc. According to the framework of ICF, recreational physical activities promote functional rehabilitation for adults with disabilities, including physical functions (b1 mental function; b4 cardiovascular, blood, the function of the immune system and respiratory system; b5 digestion, metabolism and function of the endocrine system; and b7 nerve musculoskeletal function related to movement), and activities and participation (d1 study and application of knowledge; d2 the general tasks and requirements; d4 activity; d5 self-care; d7 interpersonal communication and interpersonal relationship; and d9 community, social and civic life). The evidences showed benefits of improvement in the fields of body mass index, body index, athletic ability, balance ability, and cognitive function. There were more gains at individual levels, including support, coping with stress, self-concept development, life satisfaction, happiness, exercise self-efficacy, health perception, etc. The environmental and personal factors had effects on the performance of activity and participation in recreational physical activities, including e1 products and technologies, e4 attitude, e3 support and interpersonal relationships, e5 service system and policy, as well as attitudes and support of family members and colleagues, interpersonal relationships, social support, transportation, equipment and facilities, and policies. Conclusion:Rehabilitation exercise is an important part of health-related services. We scoped the recreational physical activities and its functional effects for adults with disabilities. The categories and structure of recreational physical activities and rehabilitation exercises were constructed based on ICF. Aligning rehabilitation exercises and relevant factors to ICF, the recreational activities and rehabilitation exercises had been reviewed and discussed and several recommendations for further studies had been drawn.
