Rice (Oryza sativa L.), as a thermophilic crop, is highly susceptible to cold stress during its growth process. Chilling injury at the plumule stage and seedling stage often affects the morphological development and leads to yield reduction of rice. The exploration and utilization of cold tolerance genes are among the most direct and effective approaches to address cold stress in rice. To identify quantitative trait loci (QTLs) associated with cold tolerance at plumule and seedling stages, in this study, we measured the seedling rates and survived seedling rates of the indica rice cultivar 'HZ', the japonica cultivar 'Nekken2', and their 120 recombinant inbred lines (RILs) under cold stress. A previously constructed high-density genetic linkage map was used for the mapping of the QTLs conferring cold tolerance at the plumule and seedling stages. A total of 4 QTLs for plumule-stage cold tolerance and 9 QTLs for seedling-stage cold tolerance were detected, with the maximum limit of detection reaching 5.20. Notably, a genetically overlapping QTL for both plumule and seedling stages was identified on chromosome 8, spanning a physical interval of 24 432 953-25 295 129 bp. Candidate genes within the detected QTL intervals were screened, and quantitative real-time polymerase chain reaction (qRT-PCR) was conducted to analyze the gene expression during the plumule and seedling stages. The results revealed that LOC_Os03g06570, LOC_Os03g07100, LOC_Os06g08280, LOC_Os08g38440, LOC_Os08g39100, and LOC_Os08g39540 exhibited significantly differential expression between the parental lines. These genes were either significantly downregulated or upregulated under cold stress. Among them, the first three gene (LOC_Os03g06570, LOC_Os03g07100, and LOC_Os06g08280) were hypothesized to be key candidates regulating the cold tolerance of rice seedlings, while the latter three genes (LOC_Os08g38440, LOC_Os08g39100, and LOC_Os08g39540) were identified as comprehensive regulators of cold tolerance during both plumule and seedling stages. These findings lay a foundation for the fine mapping and cloning of cold tolerance genes at the plumule and seedling stages, providing valuable insights for breeding cold-tolerant rice varieties.

Objective:To investigate the distribution of physical and chemical water improvement areas of drinking water-borne endemic fluorosis in Inner Mongolia Autonomous Region, as well as the use of household water purifiers.Methods:From April to October 2021, a survey was conducted in a drinking water-borne endemic fluorosis areas in Inner Mongolia Autonomous Region where physical and chemical water improvement was carried out. The survey included the basic situation of the affected villages (number of permanent households, number of permanent residents, historical water fluoride content) and the use of residential water purifiers. Household peripheral water samples were collected to test the water fluoride content. Water purifier installation rate, normal usage rate, qualified water fluoride rate in normal usage, and the proportion of households covered by filter replacement departments were calculated.Results:In Inner Mongolia Autonomous Region, the physical and chemical water improvement areas of drinking water-borne endemic fluorosis were distributed in 2 735 villages in 11 leagues (cities) throughout the region, with 192 950 permanent households and 540 216 permanent residents. The average historical water fluoride content in all leagues (cities) was 2.18 mg/L, and the current average water fluoride content was 0.40 mg/L. A total of 134 763 water purifiers were installed, with an installation rate of 69.84% (134 763/192 950). A total of 10 773 households were surveyed, with 10 396 households using water purifiers normally and a normal usage rate of 96.50% (10 396/10 773). Among them, 10 158 households had qualified water fluoride of normal usage, with a qualified water fluoride rate of 97.71% (10 158/10 396). Of the 10 396 households using water purifiers normally, 3 974 households (38.23%) had filter cartridges used within one year, and 3 961 households had qualified water fluoride, with a qualified rate of water fluoride of 99.67% (3 961/3 974). Six thousand four hundred and twenty-two households (61.77%) had filter cartridges used for more than one year, with 6 197 households had qualified water fluoride and a qualified rate of water fluoride of 96.50% (6 197/6 422). There was a statistically significant difference in the qualified rate of water fluoride between purifiers with different filter cartridge usage times (χ 2 = 110.73, P < 0.001). Among the 10 773 surveyed households, the filter cartridges replacement department covered 10 470 households, accounting for 97.19% (10 470/10 773). Conclusions:In Inner Mongolia Autonomous Region, the physical and chemical water improvement areas of drinking water-borne endemic fluorosis are widely distributed, and the normal usage rate of household water purifiers is relatively high. The qualified rate of water fluoride in household water purifiers with filter cartridges used for more than one year is low.

Acute respiratory distress syndrome is one of the common complications of sepsis syndrome, belonging to the "Chuan syndrome", "Baochuan", and "Chuantuo" in the TCM field, and the disease is mainly located in the lung. The main etiology and pathogenesis of sepsis syndrome is deficient healthy qi and blood stasis with toxin blocking collaterals. Blood stasis and toxin invade the lung, causing heat and toxin to burn the body fluid in the blood. Blood viscosity and poor circulation lead to the accumulation of blood stasis and toxin in the lung. Acute deficiency syndrome, heat toxin damaging qi, heat toxin burning body fluid deficiency with little ability to dissipate qi, resulting in deficiency of healthy qi, inability to regulate breathing, inability to consolidate body fluid, inability to promote blood circulation, causing phlegm, dampness, and blood stasis blocking the lung. This disease is characterized by blood stasis with toxin blocking collaterals, deficient lung qi, and obstruction of lung qi caused by phlegm, water, dampness, and blood stasis. Therefore, blood stasis with toxin blocking collaterals, as well as deficient healthy qi are TCM pathogenesis of ARDS with sepsis syndrome.

In the past decades, significant progress has been achived in cartilage regeneration. The traditional techniques for constructing tissue engineering cartilage scaffold mainly include pore agent method (or template method), phase separation method, gas foaming method, freeze-drying method, electrospinning method, etc. Cartilage is heterogeneous, and it is difficult for traditional scaffolds to simulate the high anisotropy of cartilage. Therefore, functional regeneration of cartilage is challenging. With the progress of three-dimensional(3D) printing technology, it is possible to prepare functional bionic scaffolds with fine structure and gradient changes through co-deposition of biomaterials, cells and active biomolecules, so as to achieve functional cartilage regeneration. This article reviewed 3D printing technology of cartilage tissue engineering, and the application of 3D printing technology in cartilage regeneration at different anatomical positions (articular cartilage, auricle cartilage, nasal cartilage). In addition, the importance of preparing bionic constructs with regional structure gradient and regional composition gradient was discussed. 3D bioprinting technology, 4D printing techniques, smart biomaterials brought hope for the construction of bionic tissues and organs.

Objective:To investigate the epidemic status of drinking-tea type endemic fluorosis (fluorosis for short) in Inner Mongolia Autonomous Region (Inner Mongolia for short), and to provide theoretical basis and basic data for formulation and evaluation of prevention and control measures.Methods:From May to October 2022, a cross-sectional survey was conducted in key areas (168 administrative villages in 6 leagues or cities) identified in the 2019 regional census with tea drinking habits, daily per capita intake of tea fluoride > 3.5 mg, and patients with skeletal fluorosis. The drinking condition of brick tea in 10 households of each administrative village was investigated, and the brick tea samples were collected to detect fluoride level. The prevalence of dental fluorosis in children aged 8 - 12 and skeletal fluorosis in adults aged 16 and older was investigated, and urine samples of patients with skeletal fluorosis were collected to detect urinary fluoride levels.Results:Totally 98.40% (1 657/1 684) of the households in the surveyed areas had a habit of drinking brick tea, with an annual per capita consumption of brick tea and a daily per capita intake of tea fluoride of 5.07 kg and 5.38 mg, respectively. The qualified rate of fluoride level in brick tea samples was 55.64% (922/1 657), the average fluoride level of all other brick tea varieties exceeded the national standard limit (300 mg/kg) except for black brick tea (291.08 mg/kg). Totally 2 747 children aged 8 to 12 were examined, with a detection rate of 13.91% (382/2 747) for dental fluorosis. The disease was mainly mild. There was no statistically significant difference in the detection rate of dental fluorosis among different age groups (χ 2 = 5.53, P = 0.238). Totally 71 708 adults aged 16 and older were examined, and the detection rate of skeletal fluorosis was 1.02% (734/71 708). Patients were mainly aged between 50 and 70 years old, and the condition in each age group was mainly mild. Totally 715 urine samples of skeletal fluorosis patients were collected and tested, and 55.24% (395/715) of the urine samples had fluoride levels higher than 1.6 mg/L. Conclusions:In Inner Mongolia, the proportion of high fluoride brick tea in endemic areas of drinking-tea type fluorosis is high. The detection rates of dental fluorosis in children and skeletal fluorosis in adults are relatively high. The prevention and control situation of drinking-tea type fluorosis is still serious.

Objective To investigate the causal relationship between gastroesophageal reflux disease(GERD)and different phenotypes of asthma based on Mendelian randomization(MR).Methods The dataset was pooled by genome-wide association studies(GWAS),in which the GERD data contained 602 604 cases,the unspecified asthma data contained 156 078 cases,139 591 cases of obesity-associated asthma,138 474 cases of pediatric asthma,140 308 cases of allergic asthma and 136 633 cases of eosinophilic asthma.The inverse va-riance weighting method was used as the main method of MR analysis,and the weighted median method,sim-ple model,weighted models and MR-Egger conducted the supplement,and the sensitivity analysis was carried out to assess the stability of the results.Results The MR analysis showed that unspecified asthma(OR=1.61,95％CI:1.45-1.77,P＜0.01),obesity-related asthma(OR=2.40,95％CI:1.98-2.90,P＜0.01),Childhood asthma(OR=1.56,95％CI:1.25-1.94,P＜0.01)and allergic asthma(OR=1.47,95％CI:1.25-1.74,P＜0.01)present the forward cause effect,but eosinophilic asthma had no causal relation with GERD(OR=1.31,95％CI:0.95-1.81,P=0.10).The sensitivity analysis showed that the horizontal pleiot-ropy and heterogeneity in the results did not exist.Conclusion GERD could lead to an increased risk of un-specified asthma asthma,obesity-associated asthma,pediatric asthma and allergic asthma,while the effect on eosinophilic asthma is not significant.

Objective To investigate the causal association between bronchial asthma and bone mineral density at different sites using a two-sample Mendelian randomization (MR) approach. Methods Summary data for exposure factors and outcome were obtained from different genome-wide association studies.Single nucleotide polymorphisms strongly associated with bronchial asthma were selected as instrumental variables,and those in linkage disequilibrium were excluded.The inverse-variance weighted (IVW) method was used as the primary method for MR analysis,complemented by weighted median,simple mode,weighted mode,and MR-Egger regression methods.Sensitivity analyses were conducted to assess the stability of the results. Results The random-effects model of IVW analysis showed that heel bone mineral density (OR=0.986;95% CI,0.974 to 0.998;P=0.023) as the outcome dataset had a reverse causal effect with bronchial asthma,while lumbar spine bone mineral density (OR=1.031;95% CI,0.984 to 1.081;P=0.195),femoral neck bone mineral density (OR=1.014;95% CI,0.973 to 1.057;P=0.505),and forearm bone mineral density (OR=1.011;95% CI,0.935 to 1.094;P=0.775) as outcome datasets showed no causal effect with bronchial asthma.The MR-Egger intercept test results indicated that the P-values for the intercepts of lumbar bone mineral density,femoral neck bone mineral density,forearm bone mineral density,and calcaneal bone mineral density were all over 0.05,suggesting no horizontal pleiotropy and relatively stable results. Conclusion MR analysis reveals a reverse causal effect between bronchial asthma and heel bone mineral density,suggesting that clinicians should strengthen the monitoring of heel bone mineral density in patients with bronchial asthma to timely detect and intervene osteoporosis.

Objective:To investigate the epidemic scope and intensity of drinking water type endemic arsenic poisoning in Inner Mongolia Autonomous Region, as well as the prevalence and influencing factors, in order to provide scientific basis for precise formulation of prevention and control measures.Methods:A sampling survey was conducted on residents' drinking water in all villages and counties in Inner Mongolia Autonomous Region, water samples were selected according to different water supply methods (engineering water supply, physical and chemical water purification, and decentralized water supply), and the arsenic content was detected by atomic fluorescence method. The "Diagnosis of Endemic Arsenicosis" (WS/T 211-2015) was used for diagnosis of arsenic poisoning among all permanent residents who were exposing to or had been exposed to excessively high arsenic water, in order to search all the arsenic poisoning patients. Analyze the distribution of water arsenic in the historical disease areas and high arsenic villages and newly discovered high arsenic villages, and explore the prevalence and influencing factors of arsenic poisoning.Results:There were a total of 1 186 historical disease areas and high arsenic villages in Inner Mongolia Autonomous Region, mainly distributed in 28 banner counties of 8 league cities such as Bayannur, Hohhot and Baotou, with a regional distribution trend of more in the west and less in the east. At present, the water improvement rate in the historical disease areas and high arsenic villages was 98.23% (1 165/1 186), and the qualified rate of arsenic content in the water was 99.83% (1 184/1 186). The arsenic content in the water of historical disease areas and high arsenic villages ranged from 0.000 to 0.093 mg/L. Four newly discovered villages with arsenic exceeding standards had been found, and their arsenic content ranged from 0.074 to 0.142 mg/L. A total of 2 249 patients with arsenic poisoning were detected in the confirmed disease area/high arsenic villages, and the detection rate was 1.67% (2 249/134 645). The number of patients in Bayannur City was the largest with the most severe disease, accounting for 82.70% (1 860/2 249). Patients aged 60 and above accounted for 61.41% of the total cases (1 381/2 249), which was higher than other age groups (χ 2 = 840.52, P < 0.001). The detection rate of arsenic poisoning was higher in males than in females (χ 2 = 132.38, P < 0.001). There are statistically significant differences in the detection rate and severity distribution of arsenic poisoning patients among different water arsenic content groups(χ 2 = 1 557.85, 1 741.05, P < 0.001). Conclusions:After years of prevention and control work, the arsenic content in most historical disease areas and high arsenic villages in Inner Mongolia Autonomous Region is currently qualified, and some areas have water arsenic exceeding standards or newly discovered villages with arsenic exceeding standards. At the same time, there are still a large number of arsenic poisoning patients in Inner Mongolia Autonomous Region. In the future, the prevention and control of endemic arsenic poisoning in Inner Mongolia Autonomous Region cannot be relaxed, and it is necessary to strengthen water quality monitoring and improve water quality in newly discovered villages with arsenic exceeding standards to prevent the occurrence of new cases.
