Objective: To explore the prevalence of elevated blood pressure and overweight/obesity and their comorbidities among Tibetan middle school students in Lhasa, and to analyze their association with lifestyle and other factors, so as to provide a basis for the intervention measures targeting elevated blood pressure, overweight and obesity among middle school students in high altitude area. Methods: Using a stratified cluster random sampling method in September 2021, a total of 1 488 Tibetan junior and high students from Lhasa City were investigated with blood pressure measurement, physical examination and questionnaire survey. The influencing factors of elevated blood pressure, overweight and obesity and their comorbidities association were analyzed by multivariate Logistic regression. Results: The prevalence of elevated blood pressure, overweight/obesity and their comorbidities were 17.8%, 17.4% , 5.0% respectively. Multivariate Logistic regression analysis showed that age( OR =0.81), residence, body mass inex(BMI) and gender were the influencing factors of elevated blood pressure; and the risks of elevated blood pressure in female students were higher than male students ( OR =1.89), suburban students were higher than urban students ( OR =8.06), overweight and obesity groups were higher than normal groups ( OR =2.55, 2.87) ( P <0.05). Adjusting for confounding factors such as gender, residence and school, and BMI (only for elevated blood pressure), daily screen time ≥2 h was positively correlated with elevated blood pressure, overweight/obesity and its comorbidities ( OR =1.56, 1.59 , 2.51) ( P <0.05). Conclusions The prevalence of elevated blood pressure, overweight/obesity are relatively high in Lhasa. Longer screen time is a common factor affecting with elevated blood pressure, overweight/obesity and comorbidities among Tibetan students. Measures should be taken intervene in the lifestyle of Tibetan students, in order to reduce elevated blood pressure and overweight/obesity.

Objective:To evaluate the relationship between prognostic nutritional index (PNI) and risk of functional dependence in patients receiving maintenance hemodialysis (MHD).Methods:It was a cross-sectional survey study. The clinical data of MHD patients in the Second Affiliated Hospital of Soochow University from June to December 2023 were collected. The Katz and Lawton-Brody questionnaires were used to assess the functional status. The patients were divided into normal functional status group and functional dependence group, and the differences of the clinical data between the two groups were compared. Serum albumin and lymphocytes were used to determine PNI, and the patients were divided into four subgroups: Q1 group (PNI≤44.3), Q2 group (44.349.8) according to the quartile of PNI. Logistic regression analysis method was used to analyze the relationship between PNI and risk of functional dependence in MHD patients, and subgroup analysis was conducted. The receiver-operating characteristic (ROC) curve was used to assess the efficacy of PNI, serum albumin, and lymphocytes in predicting the risk of functional dependence in MHD patients.Results:A total of 206 MHD patients were included in this study, with age of (58.35±0.98) years old, and 132 (64.1%) males. There were 58 (28.2%) patients with diabetes, 179 (86.9%) patients with hypertension, and 36 (17.5%) patients with cardiovascular diseases. There were 95 (46.1%) patients developing functional dependence. Compared with normal functional status group, functional dependence group had higher age ( t=-6.87, P<0.001), proportion of diabetes ( χ2=6.58, P=0.010), and pulse pressure ( t=-3.17, P=0.002), and lower diastolic pressure ( t=3.88, P<0.001), serum creatinine ( t=3.44, P=0.001), serum albumin ( t=4.09, P<0.001) and PNI ( t=3.92, P<0.001). The incidence of functional dependence in PNI Q1 group (69.2%, 36/52) was significantly higher than those in Q2 group (49.0%, 25/51), Q3 group (34.0%, 18/53) and Q4 group (32.0%, 16/50), and the differences among groups were statistically significant (all P<0.05). Logistic regression analysis showed that after adjusting for confounding factors: age, diabetes, pulse pressure, and serum creatinine, the risk of functional dependence of PNI Q1 group was 3.217 folds higher than that in Q4 group ( OR=3.217, 95% CI 1.229-8.422, P=0.017). The risk probability model of PNI predicting the occurrence of functional dependence in MHD patients: logit (odds)=5.854-0.128 3×PNI. The area under the ROC curve ( AUC) for PNI predicting the risk of functional dependence in MHD patients was 0.66 (95% CI 0.58-0.73, P<0.001), slightly higher than that of serum albumin ( AUC=0.64, 95% CI 0.54-0.73, P<0.001). The optimal cutoff value of PNI predicting the occurrence of functional dependence was 46.15, with sensitivity of 72.07% and specificity of 57.89%. Conclusion:Low PNI is associated with high risk of functional dependence in MHD patients.

Objective:To investigate clinical and histopathological features of adult erythema nodosum (EN) .Methods:Clinical data were collected from 54 adult inpatients with histopathologically confirmed EN in Department of Dermatology and Venereology, the First Affiliated Hospital of Wannan Medical College from November 2019 to July 2022, and analyzed retrospectively.Results:Among the 54 EN patients, there were 6 males and 48 females, their ages were 42.50 ± 11.68 years (range, 18 - 73 years), and their disease course ranged from 1 day to 10 years; 30 patients (55.56%) were diagnosed with idiopathic EN, and 24 (44.44%) with secondary EN. The most common etiological factor in secondary EN was infection (17 cases), including respiratory tract infection (9 cases), tuberculosis infection (6 cases), upper respiratory tract infection comorbid with active hepatitis B virus infection (2 cases) ; the following common etiological factor was connective tissue disease (7 cases), including Behcet′s syndrome (4 cases), Sj?gren′s syndrome (1 case), and undifferentiated connective tissue diseases (2 cases). The patients′ ages were significantly younger in the secondary EN group (38.33 ± 12.15 years) than in the idiopathic EN group (46.17 ± 10.20 years, t = 2.58, P = 0.013). All patients had skin lesions on their lower limbs, lesions were limited to both lower limbs in 24 patients with idiopathic EN and 12 with secondary EN, and the proportion of patients with lesions limited to both lower limbs was significantly lower in the secondary EN group than in the idiopathic EN group ( χ2 = 5.44, P = 0.020). Compared with the idiopathic EN group, the secondary EN group showed significantly increased white blood cell counts ([7.56 ± 2.46] × 10 9/L vs. [6.04 ± 1.60] × 10 9/L, t = 2.62, P < 0.05) and C-reaction protein levels (34.34 ± 46.48 mg/L vs. 11.45 ± 18.13 mg/L, t = 2.28, P < 0.05). In the idiopathic EN group, 23 patients mainly showed histopathological features of septal panniculitis, while 17 patients in the secondary EN group mainly showed histopathological features of mixed panniculitis or lobular panniculitis, and the proportion of patients with histopathological features of mixed panniculitis or lobular panniculitis was significantly higher in the secondary EN group than in the idiopathic EN group ( χ2 = 12.18, P < 0.001) . Conclusion:EN was more common in female adults; idiopathic EN was the most common type, and secondary EN may be a cutaneous sign of systemic diseases; for EN patients at a relatively young age, with lesions involving both lower limbs or more sites, higher white blood cell counts and C-reaction protein levels, and histopathological manifestations of lobular panniculitis, systemic examinations were required to rule out underlying causes.

The mouse body weight during the modeling pe-riod was recorded, and peripheral blood routine and the number of mononuclear cells in the bone marrow of femur were measured. Histopathology of spleen was de-tected, also the index and cellularity of spleen were analyzed. BFU-E of spleen mononuclear cells was counted. The number of F4/80

Objective To explore the optimal administration route of tranexamic acid (TXA) in shoulder arthroscopic surgery. Methods Patients undergoing arthroscopic rotator cuff repair were randomly divided into four groups: control group (without TXA treatment), intravenous group (TXA was intravenously administered 10 minutes before surgery), irrigation group (TXA was added to the irrigation fluid during subacromial decompression and acromioplasty), and intravenous plus irrigation group (TXA was applied both intravenously and via intra-articular irrigation). The primary outcome was visual clarity assessed with visual analog scale (VAS) score, and the secondary outcomes included irrigation fluid consumption and time to subacromial decompression and acromioplasty procedure. Results There were 134 patients enrolled in the study, including 33 in the control group, 35 in the intravenous group, 32 in the irrigation group, and 34 in the intravenous plus irrigation group. The median and interquartile range of VAS scores for the intravenous, irrigation, and intravenous plus irrigation groups were 2.70 (2.50, 2.86) (Z = -3.677, P = 0.002), 2.67 (2.50, 2.77) (Z = -3.058, P < 0.001), and 2.91 (2.75, 3.00) (Z = -6.634, P < 0.001), respectively, significantly higher than that of the control group [2.44 (2.37, 2.53)]. Moreover, the control group consumed more irrigation fluid than the intravenous group, irrigation group, and intravenous plus irrigation group (all P < 0.05). The intravenous plus irrigation group consumed less irrigation fluid than either the intravenous group or the irrigation group (both P < 0.001). There was no difference in subacromial decompression and acromioplasty operative time among the four groups. Conclusion TXA applied both topically and systematically can improve intraoperative visual clarity, and the combined application is more effective.

Betulinic acid (BA) exerts protective effects on organs in septic animals. However, whether BA can improve cardiac function in sepsis and the underlying mechanism remain unclear. Here, male Sprague-Dawley rats were pretreated with BA (25 mg/ kg/ d, i. g.) for 5 days and then intraperitoneally injected with lipopolysaccharide (LPS, 10 mg/ kg). The rats were anesthetized to determine transthoracic echocardiography using a high-resolution imaging system for small animals after they were treated with LPS for 6 h. Histopathologic alterations were examined by HE staining. Myocardial injury markers (cTnI and CK-MB) and inflammatory factors (TNF-α, IL-1β and IL-6) in the serum were measured by the enzyme-linked immunosorbent assay. Autophagy-related proteins (p62 and LC3 Ⅱ) and AKT-modulated autophagy pathways in the myocardium were determined by Western blotting. Pretreatment with BA markedly improved left ventricular ejection fraction (EF) and fraction shortening (FS) (P<0. 05), improved myocardial histomorphology, and significantly inhibited cTnI, CK-MB, TNF-α, IL-1β and IL-6 (P<0. 05) in the septic rat serum. BA markedly decreased p62 (P<0. 01), increased LC3 Ⅱ (P< 0. 001), and significantly down-regulated p-AKT (Thr308), p-AMPKα (Ser485/ 491), p-mTOR (Ser2448) and p-S6K (Thr389) (P<0. 05), while markedly up-regulated p-AMPKα (Thr172) and pULK1 (Ser317) (P<0. 01) in septic rat hearts. The findings indicate that BA can attenuate sepsis-induced myocardial dysfunctions associated with down-regulating autophagy inhibiting pathways mediated by AKT/ mTOR and AKT/ AMPK pathways.

Mucosal pemphigoid is a rare subepidermal immune bullous disease, mainly involving the oral cavity, eyes and other mucous membranes, with the risk of scarring, which can be life-threatening in severe cases. For patients with mucosal pemphigoid, early diagnosis and early treatment can avoid serious complications. For mild patients, dapsone or topical glucocorticoids can be used; for severe patients, combination of immunosup-pressants helps to improve clinical efficacy and reduce the dosage of glucocorticoid, including cyclophosphamide, azathioprine, methotrexate, and mycophenolic acid esters. For some refractory cases without any response to the treatments of dapsone, glucocorticoids and immunosuppressants, biological agents (including rituximab, etanercept, infliximab, and braziltinib), intravenous immune globulin and other therapies can be selected. For some patients with mucosal scarring, surgery or laser therapy can be considered to improve symptoms. However, it is necessary to further demonstrate the clinical efficacy of some immunosuppressants and biologic agents on mucosal pemphigoid in a lot of larger clinical trials.
