Colorectal inflammatory cancer transformation poses a major risk to patients with colitis. Patients with chronic intestinal inflammation have an approximately 2-3 folds increased risk of developing colorectal cancer (CRC). Unfortunately, there is currently no effective intervention available. Huangqin decoction (HQD), a well-known traditional Chinese medicine (TCM) formula, is frequently clinically prescribed for treating patients with colitis, and its active ingredients have effective antitumour efficacy. Nonetheless, the mechanism of HQD-mediated prevention of colorectal inflammatory cancer transformation remains unclear. A strategy integrating metagenomic, lipidomic, and messenger RNA (mRNA) sequencing analysis was used to investigate the regulatory effects of HQD on the gut microbiome, metabolism and potential mechanisms involved in colorectal inflammatory cancer transformation. Our study revealed that HQD suppressed colorectal inflammatory cancer transformation, which was associated with enhanced intestinal barrier function, decreased the inflammatory response, and regulation of the gut microbiome. Notably, cohousing experiments revealed that the transfer of the gut microbiome from HQD-treated mice largely inhibited the pathological transformation of colitis. Moreover, gut microbiome transfer from HQD-treated mice primarily resulted in the altered regulation of fatty acid metabolism, especially the remodeling of arachidonic acid metabolism, which was associated with the amelioration of pathological transformation. Arachidonic acid metabolism and the key metabolic enzyme arachidonic acid 12-lipoxygenase (ALOX12) were affected by HQD treatment, and no obvious protective effect of HQD was observed in Alox 12 ^-/- mice, which revealed that ALOX12 was a critical mediator of HQD protection against colorectal inflammatory cancer transformation. In summary, multiple omics analyses were applied to produce valuable data and theoretical support for the application of HQD as a promising intervention for the transformation of inflammatory CRC.

Objective To explore the effect of sling exercise with Tuina therapy on kinesiophobia in old patients with lumbar disc herniation,and analyze the mechanism based on brain-bone axis. Methods A total of 56 old patients with chronic lumbar disc herniation and kinesiophobia were selected from the Reha-bilitation Hospital of the Second Affiliated Hospital of Shandong University of Traditional Chinese Medicine from September,2022 to December,2023;and randomly divided into control group(n=28)and experimental group(n=28).The control group accepted conventional exercise therapy,while the experimental group accepted sling exercise with Tuina therapy,for four weeks.They were assessed with simplified Chinese version of Tampa Scale of Kinesiophobia(TSK),Japanese Orthopaedic Association score(JOA)and Visual Analogue Scale for pain(VAS)before and after treatment,while the bone mineral density(BMD)was tested,the levels of osteoprote-gerin(OPG),norepinephrine(NE)and corticosteroids(Cor)in serum were measured,and the median frequency(MF)of weak-link erector spinae was detected with surface electromyography. Results Two cases dropped off in the control group,and one in the experimental group.The scores of all the assessment improved in both groups after treatment(|t|>14.168,P<0.001),as well as the serum levels of OPG,NE and Cor(|t|>2.103,P<0.05),BMD(|t|>2.726,P<0.05),and MF of erector spinae(|t|>14.736,P<0.001);all of them were better in the experimental group than in the control group(|t|>2.154,P<0.05). Conclusion Sling exercise with Tuina therapy can improve the pain and kinesiophobia of lumbar disc herniation in the old adults,which may promote the recovery of physical and mental function through regulating the levels of hor-mones and neurotransmitters related to the brain-bone axis.

OBJECTIVE To explore the distribution of airborne pollen in Cangzhou,to analyze the correlation between pollen characteristics,meteorological factors and the rate of allergic rhinitis visits,and to provide a reference basis for the precise prevention and treatment of allergic rhinitis in Cangzhou.METHODS The gravity deposition method was applied to collect daily airborne pollen from the monitoring sites in Cangzhou from March to October 2022 and record the pollen species and quantities.We also collected information on allergic rhinitis patients who visited the ENT Department of Cangzhou Central Hospital during the same period and meteorological data(daily maximum temperature,minimum temperature,maximum relative humidity,maximum precipitation,and maximum wind speed at ground level)during the same period,and analyzed the relationship between the number of AR patients'visits,the amount of pollen,and the meteorological factors.RESULTS 1.A total of 229 pollen exposures were collected from March to October 2022,totaling 19 368 pollen grains,of which 18 750 grains of pollen could be identified in 19 families and 618 grains were difficult to identify the families.2.There were two peaks of pollen during the period,in April and September respectively.Spring pollen to tree-based category,to the pine family,willow willow family,Xylariaceae(ash)most often;summer pollen volume has declined,but still tree-based category;fall pollen to herbaceous category,to the Asteraceae Artemisia,mulberry,Gramineae most often.3.The pollen concentration in Cangzhou City was negatively correlated with maximum humidity,maximum precipitation,maximum temperature,and minimum temperature.Maximum wind speed at ground level was positively correlated with pollen concentration.4.Pollen concentration was positively correlated with the number of visits.The correlation analysis between daily medical visits from June to October and air pollen concentration showed a significant positive correlation,while the results from March to May showed no significant correlation.CONCLUSION The peak of airborne pollen dispersal in April and September in Cangzhou.Spring and summer pollen is dominated by tree species,and the dominant pollen is Pinaceae,Willow genus of Populus,and Xylariaceae(ash genus);fall pollen is dominated by herbaceous species,and the dominant pollen is Artemisia,Asteraceae,Mulberry,and Gramineae.Meteorological factors are important factors affecting pollen concentration.Within a certain range,the lower the maximum humidity,the lowest maximum precipitation,the lower the highest or the lowest temperature,the higher the pollen concentration,and the pollen concentration is more affected by the lowest temperature.There is a correlation between pollen concentration and the number of AR patients'visits from June to October,which can be used as an environmental early warning indicator of the prevalence of AR.

Schizophrenia is a severe mental illness with a significant disease burden.The interaction between oxidative stress and pro-inflammatory factors promotes chronic neuroinflammation and immune damage,leads to dysregulation of dopaminergic and glutamatergic pathways and occurrence of psychotic symptoms and is believed to be closely related to the pathogenesis of schizophrenia.In this paper,we aim to identify biomarkers within the tryptophan kynurenine metabolic pathway,the WNT/β-Catenin pathway and the NF-κB pathway,and dopamine metabolism.These pathways have been extensively studied and are known to be involved in the interac-tion between inflammation and oxidative stress.We will also explore the potential application of related antioxidants in the diagnosis and treatment of schizophrenia,summarizing their current research progress.

OBJECTIVE To comprehensively evaluate the effectiveness， safety and economics of linaclotide in the treatment of constipated irritable bowel syndrome （IBS-C）， and to provide the evidence-based basis for clinical application. METHODS Rapid health technology assessment method was adopted； PubMed， Embase， the Cochrane Library， Web of Science， CNKI， Wanfang data， VIP database， SinoMed， and related HTA websites were searched. Systematic review/meta-analysis， HTA reports and pharmacoeconomic research about linaclotide were collected. After literature screening， data extraction and quality evaluation， descriptive analysis was used to classify and summarize the research results. RESULTS A total of 11 literature were included， involving 7 systematic reviews/meta-analyses and 4 pharmacoeconomic research. In terms of effectiveness， compared with placebo， linaclotide could achieve FDA specified endpoint and European Medicines Agency-recommended endpoint faster， significantly improved patients’ complete spontaneous bowel movements （CSBM）， abdominal pain， constipation and quality of life， and relieved patients’ global symptoms； compared with the indirect evidence of lubiprostone， plecanatide and tenapanor， the efficacy of linaclotide at the FDA specified endpoint， CSBM， abdominal pain relief， and global relief response were the best. In terms of safety， the incidence of overall adverse drug reactions， diarrhea and flatulence caused by linaclotide were significantly higher than placebo，but patients can tolerate them. In terms of economics， compared with traditional therapeutic drugs， linaclotide showed an economic advantage. CONCLUSIONS Linaclotide has advantages in efficacy， safety and economics in the treatment of IBS-C. It is an effective strategy for the treatment of IBS-C.

Objective:To explore the relationship between thyroid parenchymal echogenicity abnormalities and thyroid function evolution in health examination population.Methods:It was a cohort study. According to the inclusion and exclusion criteria, participants were selected from individuals who underwent thyroid color ultrasound and thyroid function tests at the Health Management Center of Tianjin Medical University General Hospital from January to December 2017. Data including age, gender, smoking history, alcohol consumption history, personal medical history, and thyroid function re-examination information were collected. Follow-up was conducted until the occurrence of thyroid function abnormalities or until the end of the follow-up period. The cumulative incidence rate and incidence density of thyroid function abnormalities were evaluated. Cox regression analysis was used to analyze the relationship between thyroid parenchymal echogenicity abnormalities and thyroid function evolution.Results:A total of 6 754 participants were included in this study, with an average age of (45.80±12.12) years, and females accounted for 42.7%. The mean follow-up time was 1.82 years, with a cumulative follow-up duration of 12 263 person-years. During the follow-up period, 154 new cases of thyroid function abnormalities occurred, with a cumulative incidence rate of 2.28% (95% CI: 1.94%-2.66%) and an incidence density of 12.56/1 000 person-years (95% CI: 10.66/1 000-14.69/1 000 person-years). The multivariate adjusted Cox regression analysis showed that individuals with thyroid parenchymal echogenicity abnormalities had a significantly increased risk of developing isolated thyroid stimulating hormone abnormalities and thyroid function abnormalities, with HR(95% CI) of 3.09 (2.02-4.73) and 2.92(1.96-4.33), respectively, both P<0.001. Stratified analysis showed that, except for body mass index <18.5 kg/m 2, current smoking, and current alcohol consumption, all other stratified factors showed a significant increase in the risk of thyroid function abnormalities in individuals with thyroid parenchymal echogenicity abnormalities. Conclusion:Thyroid parenchymal echogenicity abnormalities are important risk factors for the evolution of thyroid function abnormalities. Continuous monitoring of thyroid function should be given due attention.

Objective:To investigate the clinical features and prognosis of extranodal nasal-type NK/T-cell lymphoma of the extra-upper aerodigestive tract (extra-UADT NKTCL).Methods:The clinical data of 159 patients with extra-UADT NKTCL from the China Lymphoma Collaborative Group (CLCG) database between November 2001 and December 2015 were retrospectively analyzed. Kaplan-Meier survival analysis and Log-rank test were used to evaluate the prognosis. The Cox regression model is used for multi-factor analysis.Results:Extra-UADT NKTCL commonly occurs in skin and soft tissues (106/159, 66.7%) and gastrointestinal tract (31/159, 19.5%). The incidences of elevated lactate dehydrogenase (LDH) and Ann Arbor Ⅲ~Ⅳ stage were 47.8% (76/159) and 64.2% (102/159), respectively. The 3-year overall survival (OS) and progression-free survival (PFS) rates were 43.6% and 27.9%, respectively. The corresponding OS rates of primary skin/soft tissue site and gastrointestinal tract site were 41.0% and 59.4% ( P=0.281), while the PFS rates were 24.8% and 48.3%, respectively ( P=0.109). Combined modality treatment improved the 3-year OS of all the patients (58.4% vs 33.9%, P=0.001) and 3-year PFS (40.7% vs 20.7%, P=0.008) when compared with chemotherapy alone. LDH elevation, Ann Arbor synthesising and ≥2 junction external bits were intrusive as independent risk factors for total survival ( P<0.05), LDH elevation and ≥2 junction outer bits were intrusive as independent risk factors for progressionless survival( P<0.05). The distant extranodal dissemination was the primary failure patterns. Conclusions:Extra-UADT NKTCL appears to have distinct clinical characteristics and poor outcome. Compared with chemotherapy alone, combined modality treatment may improve the prognosis of patients with extra-UADT NKTCL.

Objective:To evaluate the prognosis and determine the failure patterns after radiotherapy for low-risk early-stage patients with extranodal NK/T-cell lymphoma, nasal-type (ENKTCL).Methods:A total of 557 patients from 2000—2015 with low-risk early-stage ENKTCL who received radiotherapy (RT) with or without chemotherapy (CT) from China Lymphoma Collaborative Group were retrospectively reviewed. Among them, 427 patients received combined modality therapy, whereas 130 patients received RT alone. Survivals were calculated by Kaplan-Meier method and compared with Log-rank test. Overall survival (OS) was compared with age and sex-matched general Chinese population using expected survival and standardized mortality ratio (SMR). Cox stepwise regression model was used for multivariate analysis.Results:The 5-year OS and progression-free survival (PFS) were 87.2% and 77.2%. The SMR was 3.59 ( P<0.001) at 1 year after treatment, whereas it was 1.50 at 4 years after treatment, without significant difference between ENKTCL group and country-matched general population ( P=0.146). Compared with RT alone, CMT did not result in significantly superior 5-year OS (87.0% vs 87.4%, P=0.961) or PFS (76.1% vs 80.7%, P=0.129). Local failure (11.5%, 64/557) and distant failure (10.8%, 60/557) were the main failure modes, while regional failure was rare (2.9%, 16/557). The 5-year locoregional control rate (LRC) was 87.2% for the whole group, with 89.5% for ≥50 Gy versus 73.7% for <50 Gy ( P<0.001). Radiotherapy dose was an independent factor affecting LRC( P<0.05). Conclusions:Radiotherapy achieves a favorable prognosis in patients with low-risk early-stage ENKTCL. The incidence of either locoregional or distant failure is low. Radiation dose still is an important prognostic factor for LRC.
