Objective We aimed to (i) observe the therapeutic effect of Yiqi Wenyang Prescription (YQWYP, which consists of milkvetch root, tangshen, dried ginger, cassig twig, ephedra, biond magnolia flower-bud, Chinese magnoliavine fruit, earthworm, and liquorice root) on an allergic rhinitis (AR) murine model and the protective effect on the tight junction (TJ) key proteins zonula occludens-1 (ZO-1) and occludin and (ii) elucidate whether YQWYP exerts these effects by inhibiting autophagy in nasal mucosal cells.Methods Thirty C57BL/6 mice were randomly divided into six groups with 5 mice per group: (i) the blank group, (ii) the model group, (iii-v) the YQWYP low-dose, mid-dose, and high-dose groups(7, 14, 28 g/kg), and (vi) the cetirizine group(1.667 mg/kg). The model was established by intraperitoneal injection and nasal stimulation of ovalbumin. 1 hour before the nasal stimulation, mice in the blank group or in the model group were given normal saline by gavage, mice in the YQWYP groups and those in the cetirizine group were given the corresponding medicines solution by gavage. After 7 days, mice behavior was scored. After that, the mice were sacrificed and the nasal mucosa tissues were harvested. The inflammatory reaction of the nasal mucosa was observed by HE staining, the proliferation of goblet cells in the nasal mucosa was observed by PAS staining, the IgE content in nasal lavage fluid was determined by ELISA, the expression levels of ZO-1 and occludin were analyzed by immunohistochemistry, and the expression levels of LC3B, P62, and Beclin1 in the nasal mucosa of the blank group, model group, and YQWYP high-dose group were analyzed by Western blotting.Results After the successful establishment of the AR model, compared with the blank group, the symptom scores of nose scratching, sneezing, and runny nose in the model group were higher, while the total scores was significantly higher(P<0.01). In the model group, the nasal mucosal epithelium was disrupted and destroyed, a large number of inflammatory cells were infiltrated, goblet cells showed hyperplasia, mucus production was increased, mucosal swelling was obvious, the amount of IgE in nasal lavage fluid was increased (P<0.01). The protein expression levels of ZO-1 and occludin were decreased (P<0.05), the protein expression levels of LC3BⅡ/Ⅰ and Beclin1 were increased (P<0.05), P62 protein expression was decreased (P<0.05). After medication intervention, compared with the model group, in the YQWYP high-dose group and the cetirizine group, the total score were reduced (P<0.01), the swelling of the nasal mucosa was reduced, the infiltration of inflammatory cells was inhibited, the number of goblet cells was decreased, the amount of IgE in nasal lavage fluid was reduced(P<0.01), the protein expression of ZO-1 and occludin were increased (P<0.05), the protein levels of LC3BII/I and Beclin1 were decreased (P<0.05), P62 protein expression was increased (P<0.05). Conclusion YQWYP has a good therapeutic effect on AR mice, and its mechanism may be related to the promotion of nasal mucosal repair by inhibiting autophagy of nasal mucosal cells.

Objective To evaluate the diagnostic value of histopathological examination of ultrasound-guided puncture biopsy samples in extrapulmonary tuberculosis(EPTB). Methods This study was conducted at the Shanghai Public Health Clinical Center.A total of 115 patients underwent ultrasound-guided puncture biopsy,followed by MGIT 960 culture(culture),smear,GeneXpert MTB/RIF(Xpert),and histopathological examination.These assays were performed to evaluate their effectiveness in diagnosing EPTB in comparison to two different diagnostic criteria:liquid culture and composite reference standard(CRS). Results When CRS was used as the reference standard,the sensitivity and specificity of culture,smear,Xpert,and histopathological examination were(44.83%,89.29%),(51.72%,89.29%),(70.11%,96.43%),and(85.06%,82.14%),respectively.Based on liquid culture tests,the sensitivity and specificity of smear,Xpert,and pathological examination were(66.67%,72.60%),(83.33%,63.01%),and(92.86%,45.21%),respectively.Histopathological examination showed the highest sensitivity but lowest specificity.Further,we found that the combination of Xpert and histopathological examination showed a sensitivity of 90.80%and a specificity of 89.29%. Conclusion Ultrasound-guided puncture sampling is safe and effective for the diagnosis of EPTB.Compared with culture,smear,and Xpert,histopathological examination showed higher sensitivity but lower specificity.The combination of histopathology with Xpert showed the best performance characteristics.

Objective To explore the effect of circFAT1 on myocardial injury in rats with diabetic cardiomyopathy(DCM)and the regu-latory mechanism of circFAT1 on the miR-211-5p/CCND2 axis.Methods A DCM rat model was established by injecting rats with high glucose and high fat feed combined with STZ.The rats were randomly separated into DCM,circ-NC,circFAT1,circFAT1+agomir-NC,and circFAT1+miR-211-5p agomir groups,with 20 rats in each group;rats fed regular feed were used as control.Real-time PCR was used to detect the levels of circFAT1,miR-211-5p,and CCND2in myocardial tissue and Western blotting was used to detect CCND2 expression in myocardial tissue.The levels of fasting blood glucose(FBG),total cholesterol(TC),and triglycerides(TG)of rats were recorded.Car-diac ultrasound was used to detect the cardiac function of rats.Furthermore,HE and Masson staining were used to observe the pathological morphology of myocardial tissue and TUNEL staining was used to detect myocardial apoptosis.Additionally,ELISA was used to detect the levels of interleukin-1β(IL-1β),IL-6,and tumor necrosis factor-α(TNF-α).Double luciferase reporter gene assay was used to verify the targeting relationship among circFAT1,miR-211-5p,and CCND2.Results Compared with the control group,the expression of circFAT1 and CCND2mRNA and protein and the levels of LVEF and LVFS decreased in the DCM group(P<0.05)whereas,the levels of FBG,TC,TG,LVEDd,LVEDs,CVF,cell apoptosis rate,IL-1β,IL-6,and TNF-αincreased(P<0.05).Compared with the DCM group,the levels of circFAT1,CCND2mRNA and protein,LVEF,and LVFS increased in the circFAT1 group(P<0.05),whereas the levels of FBG,TC,TG,LVEDd,LVEDs,CVF,cell apoptosis rate,IL-1β,IL-6,and TNF-α decreased(P<0.05).Furthermore,miR-211-5p agomir reversed the protective effect of circFAT1 on DCM myocardial injury,and the expression of CCND2mRNA and protein decreased(P<0.05).Conclu-sion circFAT1 alleviates myocardial tissue damage in rats with DCM by regulating the miR-211-5p/CCND2 axis.

The incidence of osteoporotic thoracolumbar vertebral fracture (OTLVF) in the elderly is gradually increasing. The kyphotic deformity caused by various factors has become an important characteristic of OTLVF and has received increasing attention. Its clinical manifestations include pain, delayed nerve damage, sagittal imbalance, etc. Currently, the definition and diagnosis of OTLVF with kyphotic deformity in the elderly are still unclear. Although there are many treatment options, they are controversial. Existing guidelines or consensuses pay little attention to this type of fracture with kyphotic deformity. To this end, the Lumbar Education Working Group of the Spine Branch of the Chinese Medicine Education Association and Editorial Committee of Chinese Journal of Trauma organized the experts in the relevant fields to jointly develop Clinical guidelines for the diagnosis and treatment of osteoporotic thoracolumbar vertebral fractures with kyphotic deformity in the elderly ( version 2024), based on evidence-based medical advancements and the principles of scientificity, practicality, and advanced nature, which provided 18 recommendations to standardize the clinical diagnosis and treatment.

Objective:To investigate the biological effects of acute high-dose radon exposure on mice.Methods:BALB/c male mice aged 6 to 8 weeks were exposed once in an HD-3 ecological radon chamber with an average radon concentration of 7 × 10 5 Bq/m 3 for 10 h. Mice were weighed, their lung tissues and blood samples were collected at 1, 2 and 3 months after exposure. Control groups were set up at the three time points with four mice in each group. For these mice, the lung tissue pathology was observed using hematoxylin-eosin (HE) staining method, routine blood tests were conducted using a hematology analyzer and the levels of superoxide dismutase (SOD) and malondialdehyde (MDA) in the serum and lung tissues were measured using corresponding assay kits. Results:The HE staining result revealed that compared to the control groups, the experimental groups exhibited thickening of alveolar walls and increased infiltration of granulocyte, whose degrees, however, reduced over time and displayed no significant difference at 3 months after exposure. There was no significant difference in body weight or blood routine between the experimental and control groups. The detection result revealed decreased SOD levels in the lung tissues at 2 months after exposure, which were (11.34 ± 1.03) U/mgprot and (9.75 ± 0.71) U/mgprot, respectively for the control and experimental groups ( t = 2.54, P < 0.05). The MDA levels in lung tissue increased at 1 month after exposure, which were(2.30 ± 0.24) and (2.77 ± 0.29) nmol/mgprot, respectively for the control and experimental groups ( t = 2.49, P < 0.05). At 3 months after exposure, the SOD and MDA levels differed insignificantly between the control and experimental groups ( P > 0.05). Conclusions:After acute high-dose radon exposure, the mice suffered damage to the lung tissue, with changes in their oxidative stress indicators being detected. However, these effects gradually diminished at 3 months after exposure. Additionally, acute high-dose radon exposure did not give rise to significant changes in the body weight or routine blood result of the mice.

OBJECTIVE: To evaluate the association between serum uric acid (SUA) and kidney function decline. METHODS: Data was obtained from the China Health and Retirement Longitudinal Study on the Chinese middle-aged and older population for analysis. The kidney function decline was defined as an annual estimated glomerular filtration rate (eGFR) decrease by > 3 mL/min per 1.73 m ². Multivariable logistic regression was applied to determine the association between SUA and kidney function decline. The shape of the association was investigated by restricted cubic splines. RESULTS: A total of 7,346 participants were included, of which 1,004 individuals (13.67%) developed kidney function decline during the follow-up of 4 years. A significant dose-response relation was recorded between SUA and the kidney function decline ( OR 1.14, 95% CI 1.03-1.27), as the risk of kidney function decline increased by 14% per 1 mg/dL increase in SUA. In the subgroup analyses, such a relation was only recorded among women ( OR 1.22, 95% CI 1.03-1.45), those aged < 60 years ( OR 1.22, 95% CI 1.05-1.42), and those without hypertension and without diabetes ( OR 1.22, 95% CI 1.06-1.41). Although the dose-response relation was not observed in men, the high level of SUA was related to kidney function decline ( OR 1.83, 95% CI 1.05-3.17). The restricted cubic spline analysis indicated that SUA > 5 mg/dL was associated with a significantly higher risk of kidney function decline. CONCLUSION The SUA level was associated with kidney function decline. An elevation of SUA should therefore be addressed to prevent possible kidney impairment and dysfunction.

OBJECTIVE: To investigate the in vivo intervention and relative mechanism of Genistein (GEN) on tumor-associated inflammatory and tumor thrombophilia in lymphoma-bearing mice. METHODS: Forty female Balb/c mice aged 5-6 weeks were injected with murine-derived Pro B-cell lymphoma cell line 38B9 to establish a lymphoma mouse model, which was randomly divided into control group, tumor-bearing group, GEN drug intervention group and cyclophosphamide (CTX）drug intervention group. Histopathologic was used to evaluate the tumorigenesis. Tumor formation was observed, and tumor tissues were collected of HE and immunohistochemical staining. ELISA and flow cytometry were used to detect the expression of inflammatory factors and the changes of thrombus indices in plasma after intervention of GEN and Cyclophosphamide (CTX) respectively. Immunohistochemistry method was used to detect the expression of CD19 in tomor tissues of tummor bearing mice. RESULTS: After 14 days of tumor bearing, the mice were tumorigenic. The lymphoma cells were diffusely distributed in the tumor tissue and the expression of CD19 in the tumor tissue was positive. The inflammatory factors such as IL-6, NETs and CLEC-2, and thrombotic indices such as TF, FIB and D-D in lymphoma-bearing mice were significantly higher than those before tumor-injection and lower than those after drug-intervention (all P<0.05). The levels of CLEC-2 and D-D in GEN group were significantly lower than those in CTX group (P<0.05). CONCLUSION Tumor-associated inflammation and thrombophilia exist in lymphoma-bearing mice. GEN shows better anti-inflammatory and anti-thrombotic effects compared with CTX by interfering with tumor inflammatory factors.

OBJECTIVE: To evaluate the short-term efficacy of proximal fibula osteotomy in the treatment of knee osteoarthritis, and to analyze the effect of osteotomy on the tension of the lateral knee soft tissue of patients and verify the reliability of the Arch string theory. METHODS: A total of 71 patients with varus knee osteoarthritis from December 2019 to March 2022 were included, 3 patients dropped out, and 68 patients completed all trials, collected 27 males and 41 females, aged from 51 to 79 years old, with an average of (68.0±7.0 ) years old. The follow-up time ranged from 4 to 12 weeks, with an average of (3.76±1.94) weeks. After admission, the patient underwent Proximal fibula osteotomy, and the tension of lateral knee soft tissue, visual analogue scale (VAS) of pain, the western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and other indicators were recorded before surgery and 1 month after surgery in the weight-bearing state. RESULTS: According to the VAS, the curative effect of a single index was evaluated by referring to the score before and after treatment by Bao Zongzhao. Thirty seven cases were markedly effective, 27 cases were effective, and 4 cases were ineffective. After surgery, 3 patients presented with weakness of dorsalis pedis extension and 1 presented with paresthesia of dorsalis pedis, which disappeared after symptomatic treatment . The VAS and WOMAC score at 1 month after operation were lower than those before operation, and the differences were statistically significant(P<0.001). The tension of lateral knee soft tissue 1 month after operation was lower than that before operation, and the difference had statistical significance(P<0.001). CONCLUSION Proximal fibula osteotomy is safe and effective in the treatment of varus knee osteoarthritis in the short term. One month after osteotomy, the tension of lateral knee soft tissue increases under weight-bearing state, but the long-term changes still need further observation and follow-up.
