Objective:To investigate the precipitating and aggravating factors in patients with fibromyalgia (FMS) compared to patients with rheumatoid arthritis (RA).Methods:This study was conducted from January 2015 to November 2021, using a cross-sectional survey research method, based on references to develop a patient-reported "onset and exacerbation triggers questionnaire", and surveyed patients with FMS and RA at the same time, and counted the types and proportions of onset and exacerbation triggers in the two groups of patients and used the chi-square test to make comparisons between the groups.Results:A total of 415 patients with FMS and 200 patients with RA participated the survey. 146 patients with FMS (35.2%) and 38 patients with RA (19.0%) reported morbidity triggers. Experiencing physical injury (71, 17.1%), wind-cold/cold-dampness (30 patients, 7.2%), mental stress (26, 6.2%), and exercise fatigue (10 patients, 2.4%) were the common morbidity triggers for FMS. More FMS patients reported to have experienced physical injuries and mental stress before the onset of the disease compared to RA patients [8.2%(17/200), χ2=5.41, P=0.020; 1.5%(3/200), χ2=6.82, P=0.009]. Exacerbation triggers were reported by 319 patients with FMS (76.9%) and 137 patients with RA (68.5%), in the order of weather changes (219 patients, 52.7%), physical labor (192 patients, 46.2%), mood swings (147 patients, 35.4%), sleep deprivation (145 patients, 34.9%), and mental stress (130 patients, 31.3%). The proportion of FMS patients with symptom exacerbation due to physical labor [46.2%(192/415)], mood swings[35.4%(147/415)], sleep deprivation[34.9%(145/415)], mental stress[31.3%(130/415)], and infection [9.3%(39/415)] was significantly higher than that of RA patients [35.0%(70/200), χ2=7.00, P=0.008; 19.5%(39/200), χ2=16.22, P<0.001; 13.5%(27/200), χ2=30.79, P<0.001; 17.5%(35/200), χ2=13.14, P<0.001; 3.0%(6/200), χ2=8.15, P=0.004). Conclusion:More than a third of FMS patients reported precipitating factors, and nearly four fifths FMS patients reported at least one aggravating trigger. FMS patients are likely to be more sensitive to environmental changes and perceived stress than RA patients.

ObjectiveThis study aims to examine the effect of Rhei Radix et Rhizoma-Coptidis Rhizoma on reducing insulin resistance in db/db mice by regulating the adenylate activated protein kinase （AMPK）/UNC-51-like kinase 1 （ULK1）/key molecule of autophagy， benzyl chloride 1 （Beclin1） pathway and elucidate the underlying mechanism. MethodSixty 6-week-old male db/db mice were studied. They were randomly divided into the model group， metformin group （0.26 g·kg^-1）， and low-， middle-， and high-dose groups （2.25， 4.5， 9 g·kg^-1） of Rhei Radix et Rhizoma-Coptidis Rhizoma. A blank group of db/m mice of the same age was set， with 12 mice in each group. After eight weeks of continuous intragastric administration， the blank group and model group received distilled water intragastrically once a day. The survival status of the mice was observed， and fasting blood glucose （FBG） was measured using a Roche blood glucose device. Fasting serum insulin （FINS） was measured using an enzyme-linked immunosorbent assay， and the insulin resistance index （HOMA-IR） was calculated. Hematoxylin-eosin （HE） staining was performed to observe the pathological changes in the liver of the mice. The protein expression levels of AMPK， Beclin1， autophagy associated protein 5 （Atg5）， and p62 in liver tissue were determined by using Western blot. The protein expression levels of autophagy associated protein 1 light chain 3B （LC3B） and ULK1 in liver tissue were determined using immunofluorescence. Real-time fluorescence quantitative PCR （Real-time PCR） was used to measure mRNA expression levels of AMPK， Beclin1， Atg5， ULK1， and p62. ResultCompared with the blank group， the model group exhibited a significant increase in body mass （P<0.01）. Additionally， the levels of FBG， FINS， and HOMA-IR significantly changed （P<0.01）. The structure of liver cells was disordered. The protein expression levels of AMPK， Beclin1， and Atg5 in liver tissue were significantly decreased （P<0.01）， while the expression level of p62 protein was significantly increased （P<0.01）. The expression levels of mRNA and proteins were consistent. Compared with the model group， the body mass of the metformin group and high and medium-dose groups of Rhei Radix et Rhizoma-Coptidis Rhizoma was significantly decreased （P<0.05）. FBG， FINS， and HOMA-IR were significantly decreased （P<0.05，P<0.01）. After treatment， the liver structure damage in each group was alleviated to varying degrees. The protein expressions of AMPK， Beclin1， Atg5， LC3B， and ULK1 were increased （P<0.05，P<0.01）， while the protein expression of p62 was decreased （P<0.01）. The expression levels of mRNA and proteins were generally consistent. ConclusionThe combination of Rhei Radix et Rhizoma-Coptidis Rhizoma can effectively improve liver insulin resistance， regulate the AMPK autophagy signaling pathway， alleviate insulin resistance in db/db mice， and effectively prevent the occurrence and development of type 2 diabetes.

Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.

Objective To investigate the predictive value of color Doppler ultrasound parameters for fetal growth restriction (FGR) induced by hypertensive disorders of pregnancy in high-altitude regions. Methods Pregnant women with gestational hypertension who were treated between July 2020 and June 2022 at the Affiliated Hospital of Qinghai University (with altitude of 2, 300 meters, were divided into group A1 with 19 cases and group A2 with 51 cases according to occurrence of FGR), Yushu People's Hospital (with altitude of 3, 700 meters, were divided into group B1 with 25 cases and group B2 with 47 cases according to occurrence of FGR), and Civil Aviation Clinical Medical College of Peking University (plain region, control group with 71 cases) were enrolled in this study. All pregnant women in each group underwent fetal color Doppler ultrasound examination of the middle cerebral artery (MCA) and umbilical artery (UA) blood flow parameters, including pulsatility index (PI), resistance index (RI), systolic/diastolic ratio (S/D), peak systolicvelocity (PSV), and cerebroplacental ratio (CPR) at 28 weeks of gestation were detected. Multivariate Logistic regression analysis was performed to identify independent risk factors for FGR in pregnant women with gestational hypertension. Receiver operating characteristic (ROC) curves were plotted to analyze the predictive value of color Doppler parametersfor FGR. Results The UA blood flow parameters (PI, RI, S/D, PSV) of the fetuses in groups A1, A2, B1, and B2 were significantly higher than those in the control group, while the MCA blood flow parameters (PI, RI, S/D, PSV) and CPR were significantly lower (P < 0.05). Among the five groups, group B1 had the highest UA blood flow parameters (PI, RI, S/D, PSV) and the lowest MCA blood flow parameters (PI, RI, S/D, PSV) and CPR (P < 0.05). Multivariate Logistic regression analysis revealed that high altitude of residence and umbilical cord abnormalities were independent risk factors for FGR in pregnant women with gestational hypertension (P < 0.05). ROC curve analysis showed that the areas under the curves for the combined prediction of FGR in pregnant women with gestational hypertension at altitudes of 2, 300 meters and 3, 700 meters using color Doppler multi-parameters were 0.906 and 0.917, respectively, indicating a significantly higher predictive performance compared to individual parameter (P < 0.05). Conclusion Color Doppler ultrasound parameters of UA and MCA bloodflow during the second trimester of pregnancy demonstrate good predictive value for FGR induced by hypertensive disorders of pregnancy in high-altitude regions at different altitudes, and the predictive performance is even higher when multiple parameters are combined.

Objective:To analyze the influencing factors of low liver regeneration in patients with hilar cholangiocarcinoma (HCCA) after portal vein embolization (PVE).Method:Clinical data of 62 patients with HCCA undergoing PVE at Henan Provincial People's Hospital (People's Hospital of Zhengzhou University) from January 2019 to March 2024 were retrospectively analyzed, including 33 males and 29 females, aged (59.1±10.3) years. Patients were divided into two groups based on the median regeneration rate of remnant liver volume (28.6%) three weeks after PVE: low regeneration ( n=31, <28.6%) and high regeneration group ( n=31, ≥28.6%). The proportion of lymph node metastasis, history of alcohol consumption, liver fibrosis, biliary tract infection, alkaline phosphatase (ALP), and tumor necrosis factor-α (TNF-α) were compared between two groups. Multivariate logistic regression analysis was used to indentify the influencing factors of low liver regeneration in patients with HCCA after PVE surgery. Results:The proportion of lymph node metastasis, history of alcohol consumption, liver fibrosis, biliary tract infection, ALP, and level of TNF-α were higher in the low regeneration group than those in the high regeneration group (all P<0.05). Multivariate logistic regression analysis showed that patients with regional lymph node metastasis ( OR=2.561, 95% CI: 1.265-5.185), history of alcohol consumption ( OR=2.616, 95% CI: 1.321-5.181), liver fibrosis ( OR=2.351, 95% CI: 1.265-4.369), biliary tract infection ( OR=2.461, 95% CI: 1.226-4.940), elevated level of ALP ( OR=2.687, 95% CI: 1.351-5.344), and elevated level of TNF-α ( OR=2.781, 95% CI: 1.452-5.326) had an increased risk of low liver regeneration after PVE (all P<0.05). Conclusion:Regional lymph node metastasis, history of alcohol consumption, liver fibrosis, biliary tract infection, and elevated ALP and TNF-α are risk factors for low liver regeneration in patients with HCCA after PVE surgery, which should be noted in clinical practice.
