Acute lateral ankle sprain (ALAS) is one of the most common sport injuries, with high incidence, recurrence and disability rates. Currently, exercise rehabilitation-based non-surgical treatment is the primary management approach for ALAS. However, there remain improper practices such as excessive immobilization or uncontrolled activity, which contribute to recurrent sprains and chronic ankle instability, significantly impairing patients′ athletic function and quality of life. To standardize the non-surgical management of ALAS, improve the cure rates, and reduce the recurrence and disability rates, Chinese Sports Rehabilitation Medicine Training Project of Chinese Medical Association, Foot and Ankle Basics and Orthopedics Group, Orthopedic Branch of Chinese Medical Doctor Association, and Sports Medicine Branch of Jiangsu Medical Association organized relevant experts to formulate Expert consensus on non-surgical treatment for acute lateral ankle sprain ( version 2025), following the principles of scientific vigor, practicality, and innovation. Thirteen recommendations were proposed for standardized treatment protocols across different healing phases, aiming to provide references for standard management of ALAS and improve the therapeutic outcomes.

Objective: To investigate the trend in disease burden of interstitial lung disease (ILD) in China from 1990 to 2021, so as to provide a reference for formulating prevention and control strategies for chronic respiratory diseases. Methods: Based on the Global Burden of Disease 2021 database, data on the number of incident cases, incidence, standardized incidence, number of deaths, mortality, standardized mortality, number of disability-adjusted life years (DALY), DALY rate, and standardized DALY rate of ILD in China were collected. The incidence, mortality, and DALY rate were used to analyze the disease burden of ILD. The estimated annual percentage change (EAPC) was employed to assess the trend in standardized incidence, standardized mortality, and standardized DALY rate of ILD from 1990 to 2021. Rate decomposition analysis was applied to identify the main contributing factors affecting the trend in disease burden. Results: In 2021, China reported 48 514 cases, 7 674 deaths, and 222 288 person-years of DALY due to ILD, representing increases of 155.43%, 159.70%, and 97.34%, respectively, compared with 1990. From 1990 to 2021, the standardized incidence and standardized mortality of ILD in China showed upward trends (EAPC=1.106% and 0.239%, both P<0.05), while the standardized DALY rate showed a downward trend (EAPC=-0.230%, P<0.05). From 1990 to 2021, the standardized incidence and standardized mortality among males showed upward trends (EAPC=1.199% and 0.520%, both P<0.05), while the trend in the standardized DALY rate was not statistically significant (P>0.05). Among females, the standardized incidence of ILD showed an upward trend (EAPC=0.966%, P<0.05), while the standardized mortality and standardized DALY rate showed downward trends (EAPC=-0.306% and -0.760%, both P<0.05). In 2021, the incidence, mortality, and DALY rate of ILD in China increased with age, peaking in the group aged ≥95 years at 14.84/105, 13.90/105, and 124.71/105, respectively. Across all age groups aged ≥55 years, the incidence, mortality, and DALY rate of ILD were consistently higher in males than in females. The increase in the number of incident cases, deaths, and DALY due to ILD in China from 1990 to 2021 was primarily influenced by population aging, with contribution rates of 42.65%, 68.25%, and 69.79%, respectively. Conclusions From 1990 to 2021, the incidence and mortality risk of ILD in China showed upward trends, while the disability risk demonstrated a downward trend. Males bore a heavier disease burden of ILD, and aging was identified as the primary factor contributing to the increased burden of ILD in China.

ObjectiveRoot rot is one of the most serious diseases in the cultivation and production of Atractylodes lancea. Trichoderma spp. are effective in the biocontrol of root rot without causing environmental pollution. This study aims to isolate and study a Trichoderma strain capable preventing and controlling root rot from the rhizosphere of A. lancea and to solve the problem of disease prevention and control in the planting and production of A. lancea. MethodTrichoderma T2204 was isolated by the dilution-coating method and identified by ITS sequencing. The inhibitory activities of T2204 and its volatiles against two pathogenic fungal strains were examined by dual-culture and co-culture experiments. The biocontrol potential of T2204 on root rot of A. lancea and the effect of T2204 on the accumulation of medicinal compounds in the rhizosphere of A. lancea were investigated by pot experiments and GC-MS， respectively. In addition， the optimal medium， photoperiod， temperature， pH， and carbon and nitrogen sources for the culture of T2204 were explored. ResultThe Trichoderma isolate T2204 was identified as T. citrinoviride and had direct inhibitory effects on two highly pathogenic strains causing root rot. In the dual-culture experiments with the two pathogenic strains， T2204 showcased the inhibition rates of 77.90% and 76.80%， respectively. In the co-culture experiments with the two pathogenic strains， the volatile organic compounds produced by T2204 showed the inhibition rates of 57.11% and 81.11%， respectively. The pot experiments showed that the survival rate of A. lancea seedlings infected by root rot reached 100% after inoculation with T2204 and was only 50% in the case without inoculation of T2204. After 150 days of cultivation， the dry weight and atractylodin content of the rhizome of A. lancea plants treated with T2204 increased by 32% （P<0.05） and 11%， respectively， compared with the untreated group. The optimal conditions for the growth of T2204 were PDA or PSA medium， photoperiod of 12 h dark/12 h light， 25-30 °C， pH 5-6， carbon sources of glucose， D-fructose， soluble starch， and maltose， and the nitrogen sources of ammonium sulfate and ammonium dihydrogen phosphate. The optimal conditions for the sporulation of T2204 were PSA or CMA medium， photoperiod of 12 h dark/12 h light， 20-30 °C， pH 8， carbon source of sucrose， and nitrogen source of sodium nitrate. ConclusionT2204 could improve the growth and root rot resistance of A. lancea and promote the accumulation of medicinal compounds. The findings laid a foundation for the industrialized production and application of T2204 in the production of A. lancea in the future.

ObjectiveTo establish a method for the analysis of oligosaccharides in Atractylodes lancea rhizome based on ultra-performance liquid chromatography tandem quadrupole-time-of-flight mass spectrometry （UPLC-Q-TOF-MS） and a method for the quantification of oligosaccharides in A. lancea rhizome based on UPLC-evaporative light scattering detector （ELSD）， and to investigate the oligosaccharide characteristics of A. lancea rhizome from different habitats. MethodUPLC-Q-TOF-MS was used to identify the oligosaccharides in A. lancea rhizome with the mobile phase of 0.1% ammonia acetonitrile solution （A）-0.1% ammonia solution （B） for gradient elution （0-0.5 min， 98%A； 0.5-2.0 min， 98%-89%A； 2.0-2.5 min， 89%-86%A； 2.5-5.5 min， 86%-80%A； 5.5-6.5 min， 80%-72%A； 6.5-9.5 min， 72%-63%A； 9.5-14.0 min， 63%-50%A； 14.0-16.0 min， 50%A； 16.0-16.5 min， 50%-98%A； 16.5-20 min， 98%A）， the column temperature of 60 ℃ and the flow rate of 0.2 mL·min^-1. Electrospray ionization （ESI） was used to collect data in negative ion mode and the detection range was m/z 50-1 500. The qualitative analysis of oligosaccharides was accomplished by retention time， relative molecular weight， primary and secondary MS information of characteristic fragment ions in combination with reference substance information. UPLC-ELSD was employed to determine the contents of nine oligosaccharides in A. lancea rhizome with the mobile phase of 0.1% ammonia acetonitrile solution （A）-0.1% ammonia solution （B） for gradient elution （0-1 min， 98%-75%A； 1-7 min， 75%-70%A； 7-18 min， 70%-55%A； 18-23 min， 55%A； 23-23.5 min， 55%-98%A； 23.5-28 min， 98%A）， the drift tube temperature of ELSD was set at 50 ℃. Principal component analysis （PCA） and orthogonal partial least squares-discriminant analysis （OPLS-DA） were used to analyze the classification and differential components between A. lancea rhizome from different habitats. ResultA total of 24 oligosaccharides， containing 11 pairs of isomers， were identified from A. lancea rhizome. Among them， compared with samples from Anhui， Chongqing， Nanjing and Shaanxi， the contents of kestose（GF2）， 1F-fructofuranosylnystose （GF4）， kestohexose （GF5）， fructo-oligosaccharide DP10 （GF9） in samples from Maoshan were statistically significant （P<0.05）， and the total mass fraction of sucrose （GF1）-GF9 reached 16.47%. The peak area ratio of fructose-fructose oligosaccharide to its isomer sucrose-fructose oligosaccharide was greater than 1 in samples from Maoshan. ConclusionThe types and contents of oligosaccharides in A. lancea rhizome vary greatly among different habitats， and the peak area ratio of fructose-fructose oligosaccharide to sucrose-fructose oligosaccharide >1 may be one of the geoherb characteristics of A. lancea rhizome， which can provide a reference for the development， utilization and quality control of this herb.

Objective:To investigate the clinicopathologic characteristics of hepatic echinococcus granulosus (HEG).Methods:Thirteen cases of HEG were collected from Linzhi People′s Hospital between January 2017 to October 2020, and their clinicopathologic features, ultrasound classi?cation, immunophenotype and histochemical data were analyzed, retrospectively and the relevant literature was reviewed.Results:Thirteen patients (5 male patients, 8 female patients) were included in this cohort, and the mean age was 40 years. The most common clinical presentation was mild abdominal distention and pain (9/13). Based on WHO-IWGE ultrasound standardized classi?cation, these cases were classified into 5 types, including type CL (1 case), type CE1 (2 cases), type CE2 (4 cases), type CE3 (3 cases) and type CE4 (3 cases). Gross examination revealed a solitary cyst localized in the liver, varying from 2.7 to 13.5 cm in diameter, and most of them(10/13)were more than 10 cm. Histopathologically, these cysts possessed a thin inner germinal layer and outer adventitial layer, and a central cavity ?lled with a clear"hydatid"?uid. The germinal layer was continuous and generated brood capsules and protoscoleces. The laminated membranes were clearly demonstrated by elastic fiber and Gomori′s stains. Inside the"mother"cyst, there were a varying number of"daughter"vesicles of variable sizes. The inflammatory reaction around the cyst consisted of eosinophils, mononuclear cells immediately next to the cyst layer and sometimes formed granuloma and giant cells resembling the Langhan′s type giant cells. The lymphoid cells were positive for CD20 and CD3. The CD68 immunohistochemistry clearly demonstrated epithelioid cells of granuloma in two cases. Moreover, immunohistochemistry revealed plasma cells were locally positive for CD38, IgG and IgG4, but not meeting the criteria for IgG4 related lesion.Conclusions:Hepatic echinococcus granulosus is a zoonotic parasitic disease prevalent in pastoral areas such as Tibet. It is important to understand its clinical features, ultrasound characteristics and histological morphology.

Endothelial cell injury is a major contributor to cardiovascular diseases.The 2,3,5,4’-Tetrahydroxystilbene-2-O-β-D-Glucoside (TSG) contributes to alleviate human umbilical vein endothelial cells (HUVECs) injury through mechanisms still know a little. This study aims to clarify the TSG effects on gene expression (mRNA and microRNA) related to oxidative stress and endoplasmic reticulum stress induced by H2O2 in HUVECs. We found that TSG significantly reduced the death rate of cells and increased intracellular superoxide dismutase activity. At qRT-PCR, experimental data showed that TSG significantly counteracted the expressions of miR-9-5p, miR-16, miR-21, miR-29b, miR-145-5p, and miR-204-5p. Besides, TSG prevented the expression of ATF6 and CHOP increasing. In contrast, TSG promoted the expression of E2F1. In conclusion, our results point to the obvious protective effect of TSG on HUVECs injury induced by H2O2, and the mechanism may through miR16/ATF6/ E2F1 signaling pathway.
