ObjectiveTo investigate the present situation of input, output, outcome and impact of all registered community-based rehabilitation stations in Inner Mongolia in China, and analyze how the input predict the output, outcome and impact. MethodsFrom March 1st to April 30th, 2025, a questionnaire survey was conducted on all registered community-based rehabilitation stations in Inner Mongolia, covering four dimensions: input, output, outcome and impact. A total of 1 365 questionnaires were distributed. The input included four items: laws and policies, human resources, equipment and facilities, and rehabilitation information management. The output included two items: technical paths and benefits/effectiveness. The outcome included three items: coverage rates, rehabilitation interventions and functional results. The impact included two items: health and sustainability. Each item contained several questions, all of which were described in a positive way. Each question was scored from one to five. A lower score indicated that the situation of the community-based rehabilitation station was more in line with the content described in the question. Regression analysis was performed using the total score of each item of input dimension as independent variables, and the total scores of the output, outcome and impact dimensions as dependent variables. ResultsA total of 1 262 valid questionnaires were collected. The mean values of input, output, outcome and impact of community-based rehabilitation stations were 1.827 to 1.904, with coefficient of variation of 45.892% to 49.239%. The regression analysis showed that, rehabilitation information management, human resources, and laws and policies significantly predicted the output dimension (R² = 0.910, P < 0.001). Meanwhile, all four items in the input dimension predicted both the outcome (R² = 0.850, P < 0.001) and impact dimensions (R² = 0.833, P < 0.001). ConclusionInput, output, outcome and impact of the community-based rehabilitation stations in Inner Mongolia were generally in line with the content of the questions, although some imbalances were observed. Additionally, the input of community-based rehabilitation stations could significantly predict their output, outcome and impact.

A chemical investigation of secondary metabolites (SMs) from Aspergillus nidulans resulted in the identification of five novel dioxopiperazine (DKP)-diphenyl ether hybrids, designated as diphenylemestrins A-E (1-5). These compounds 1-5 represent the first known dimers combining DKP and diphenyl ether structures, with compound 4 featuring an uncommon dibenzofuran as the diphenyl ether component. The structural elucidation and determination of absolute stereochemistry were accomplished through spectroscopic analysis and electronic circular dichroism (ECD) calculations. Notably, diphenylemestrin C (3) exhibited moderate cytostatic activity against NB4 cells, with a half maximal inhibitory concentration (IC₅₀) value of 21.99 μmol·L^-1, and induced apoptosis at higher concentrations.

Background The Qingcaosha Reservoir is facing issues of algal blooms and eutrophication, and the resulting increase in the level of chlorination disinfection by-products in the water has been a major concern. Objective To evaluate the impact of "Algae Monitoring and Control Program in Qingcaosha Reservoir" (hereinafter referred to as the program) on the control of trihalomethanes (THMs) in conventional finished water. Methods From 2011 to 2019, water samples were collected from the Lujiazui Water Plant once per season, one sample each time, and the concentrations of four THMs (trichloromethane, dichlorobromomethane, monochlorodibromomethane, and tribromomethane) were measured in the samples. Using 2014 when the program was implemented as a cut-off point, the entire study period was divided into two phases: pre-implementation (2011–2013) and post-implementation(2014–2019). Segmented linear regression with interrupted time series analysis was applied to assess the concentrations and trends of THMs in the finished water before and after the program launch. Results The concentration of total THMs in finished water increased by 1.561 µg·L⁻¹ (P=0.010) for each season of time extension before launching the program. The change in the concentration of total THMs in finished water was not statistically significant after the program launch, but the THMs concentration showed a decreasing trend as the slope was −0.626 (P=0.001). From 2017 until the end of 2019, the average concentration of THMs in finished water of Lujiazui Water Plant dropped to 10 μg·L⁻¹ or less. Conclusions The algae and eutrophication control measures in Qingcaosha Reservoir have achieved good results, controlling THMs in finished water at a low level, and the trend of THMs has changed from a yearly increase pattern before the program to a yearly decrease pattern after the program.

ObjectiveTo identify the functions of the AP2/ERF family members in Pinellia ternata and promote the genetic improvement of P. ternata varieties. MethodWe identified and conducted a systematic bioinformatics analysis of the AP2/ERF family member genes in P. ternata based on the three generations of transcriptome data. Real-time polymerase Chain reaction　（Real-time） PCR was employed to determine the expression pattern of AP2/ERF genes in different tissues and under different stress conditions. ResultA total of eight full-length AP2/ERF family members were identified from the transcriptome data， which were classified into three sub-gene families： AP2， ERF， and DREB. The deduced AP2/ERF proteins in P. ternata had the length of 251-512 aa， the theoretical pI of 5.29-11.72， the instability index of 45.90-82.41， subcellular localization in the nucleus， and conserved domains and motifs. AP2/ERF genes were expressed in different tissues of P. ternata， with high expression levels in the leaf. The stress response experiments showed that PtERF1 mainly responded to NaCl stress. The expression of PtERF2 and PtERF4 was significantly up-regulated under low temperature and polyethylene glycol （PEG）-simulated stress. PtERF3 responded to both low temperature and NaCl stress. The expression of PtERF5 was induced by high temperature， low temperature， NaCl and PEG stress. The expression of PtERF7 was up-regulated under high temperature， while that of PtERF8 under low temperature. ConclusionThe AP2/ERF genes in P. ternata can respond to stress and have the potential functions of regulating photosynthesis and improving root stress resistance.

Objective:To explore the value of cardiac MRI (CMRI) in evaluating left atrial function in patients with postoperative tetralogy of Fallot (rTOF) and postoperative pulmonary stenosis (rPS).Methods:Totally 67 pediatric patients (49 with rTOF, 18 with rPS) with preserved left ventricular ejection fraction (EF) were recruited between January 2019 and October 2021 in Shanghai Children′s Medical Center, School of Medicine, Shanghai Jiao Tong University. Thirty-three healthy volunteers, matched in gender and age, were included as controls from July 2017 to August 2018. Left atrial EF, strain and strain rate of three phases (reservoir, conduit and pump), left atrial volume (maximum volume index, minimum volume index and pre-atrial contraction volume index) were measured with corresponding cardiac function analysis software. Then, the differences in these parameters were analyzed between the three groups by ANOVA or Kruskal-Wallis test with post hoc comparison and Bonferroni correction.Results:Compared with controls, patients with rTOF had lower reservoir function parameters (EF, strain and strain rate), conduit EF, conduit strain, and left atrial maximum volume index ( P<0.05), but higher pump EF ( P<0.05). In patients with rPS, only the reservoir strain rate decreased compared with controls ( P<0.05), and the remaining data showed no significant difference ( P>0.05). The reservoir and conduit EF and strain in patients with rPS were higher than those in patients with rTOF ( P<0.05). Conclusions:In patients with rTOF and rPS, left atrial function has changed despite the preservation of left ventricular EF, which may be an early marker of left ventricular diastolic dysfunction. In children with rTOF, left atrial reservoir and conduit functions decreased while the pump function increased. The reservoir and pump functions in rPS were better than those in rTOF. In addition, CMRI can detect left atrial dysfunction early before it enlarged.

Objective:To investigate the effect of the Ilizarov technique in the treatment of post-traumatic lower extremity shortening with talipes equinovarus.Methods:Clinical data of patients with post-traumatic lower extremity shortening and talipes equinovarus treated by the Ilizarov technique in the Department of Orthopaedics of Xuzhou Renci Hospital from January 2013 to April 2020 were retrospectively analyzed. The annular external fixator was installed on the affected limb according to the Ilizarov principle of external fixation. 3 days after the operation, the internal and lateral screw rods were adjusted at the speed of 2 mm/d to gradually correct the talipes equinovarus. 7 days after surgery, the lower leg was lengthened at a speed of 1 mm/d. After the foot was corrected, the foot external fixator was continued to be worn for 4 to 6 weeks, and then the fixator was removed and the foot was immobilized with a brace for 6 to 8 weeks. The lower leg fixator was removed after the lower extremity length was restored and the bone mineralization at the extension site was good. The length of both lower extremities, angle of talonavicular joint, angle of plantar flexion and dorsal extension of the ankle, and range of motion of ankle were compared before surgery and at the last follow-up. At the last follow-up, the affected feet were scored and rated using the International Clubfoot Study Group (ICFSG) scoring system, which was divided into four grades: excellent, good, medium, and poor. SPSS 25.0 software was used for statistical analysis, and each measurement index and ICFSG score were expressed in Mean±SD. Paired t-test was used to compare the preoperative and last follow-up data, and P<0.05 was considered statistically significant. Results:A total of 31 patients were enrolled, including 17 males and 14 females. The age was 15-18 years old, with an average of 16.5 years old. There were 16 cases on the right side and 15 cases on the left side. The lower extremity shortening was 45-75 mm, with an average of 65 mm. The fixation time of the external fixator was 4.5-6 months after surgery, with an average of 5 months, and the follow-up time was 22-28 months, with an average of 25.5 months. The length of the affected lower extremity recovered, the shape was basically satisfactory, and the plantar gait was restored. At the last follow-up, compared with the preoperative period, the anteroposterior talocalcaneal angle of the foot (23.0°±2.1° vs. 8.5°±2.6°), from lateral talocalcaneal angle the foot (27.0°±4.3° vs. 11.2°±4.4°), ankle plantar flexion angle (24.5°±6.8° vs. 51.1°±6.5°), ankle dorsiflexion angle (5.8°±3.5° vs. -46.8°±7.0°) and ankle range of motion (30.3°±8.2° vs. 4.2°±1.6°) were statistically significant ( P <0.01). ICFSG score: The points at the last follow-up (8.0 ± 4.2) were significantly lower than that before the operation (41.9 ± 5.3) ( P<0.01), of which 18 were excellent, 9 were good, and 4 were medium. Two cases had recurrent deformities in the later stage, and the results were satisfactory after the fusion of the talonavicular joint and calcaneocuboid joint and the anteposition of the posterior tibial tendon in the second stage. There were 4 cases of toe contracture deformity, which did not recur after the release of the flexor digitorum longus tendon at the toe. Anterior ankle impingement was observed in 5 cases and improved after the arthroscopic osteophyte removal. After the lower extremity extension was in place, the external fixator was replaced by the intramedullary nail for walking in 6 patients. The infection of the nail path occurred in 7 cases, which improved after replacement of fixing pins and dressing change of the nail path. Conclusion:The application of the Ilizarov technique in the treatment of post-traumatic lower extremity shortening with talipes equinovarus has the advantages of small trauma and dynamic control of deformity correction, which can achieve good result.
