Objective:To evaluate the clinical efficacy of TCM acupoint application combined with Fuyang cupping in the treatment of chronic bronchitis with lung and kidney yin deficiency syndrome.Methods:A randomized controlled trial study was conducted. From July 2022 to July 2024, 96 patients with chronic bronchitis in our hospital were selected as the observation subjects and divided into two groups using a random number table method, with 48 cases in each group. The control group received treatment with Fuyang cupping, while the study group received treatment with Fuyang cupping and acupoint application. Both groups were treated continuously for 14 days. TCM syndrome scores were performed before and after treatment, and serum TNF-α, CRP, and procalcitonin (PCT) levels were detected using ELISA. Arterial oxygen partial pressure (PaO 2) and carbon dioxide partial pressure (PaCO 2) were measured using a blood gas analyzer. FVC, FEV1, and FEV1 percentage of predicted values (FEV1% predicted value) and maximum expiratory flow (PEF) were measured using a pulmonary function analyzer. The relief time of clinical symptoms such as cough, sputum production, and wheezing during the treatment period were observed and recorded, and the clinical efficacy was evaluated. Results:The total effective rate of the research group was 95.83% (46/48), while that of the control group was 79.16% (38/48), with statistical significance ( χ2=6.10, P=0.013). After treatment, the scores of cough, sputum, wheezing, wheezing, and dry throat and mouth in the study group were lower than those in the control group ( t values were 4.86, 5.89, 5.23, 4.10, 5.49, respectively, P<0.01); PaO 2 level [(95.63 ± 6.45) mmHg vs. (88.44 ± 5.76) mmHg, t=5.76] was higher than of the control group ( P<0.01), and the PaCO 2 level [(40.12 ± 4.28) mmHg vs. (45.63 ± 4.36) mmHg, t=6.25] was lower than of the control group ( P<0.01); the levels of FEV1 [(2.64 ± 0.69) L vs. (1.97 ± 0.74) L, t=4.59], FEV1% predicted value (79.25 ± 11.27 vs. 62.55 ± 10.56, t=7.49), FVC [(3.05 ± 1.04) L vs. (2.06 ± 0.96) L, t=4.85], and PEF [(241.54 ± 19.85) L/min vs. (221.36 ± 19.65) L/min, t=5.01] were higher than those in the control group ( P<0.01); the levels of TNF-α, CRP and PCT in the serum were lower than those in the control group ( t values were 4.39, 6.51 and 18.59, respectively, P<0.001).

Objective To evaluate clinical effect of remote ischemic conditioning(RIC)in patients with spontaneous intracerebral hemorrhage(sICH).Methods Sixty-four patients with sICH who were diagnosed and admitted to the Department of Neurosurgery,the Sixth Medical Center of PLA General Hospital from January 2023 to May 2024 were selected as research subjects.Following the principle of matching baseline characteristics between groups,a computerized random grouping program was used to divide them into an observation group of 32 cases and a control group of 32 cases.Patients in the control group received standard basic medication according to the'Chinese Clinical Management Guidelines for Cerebrovascular Diseases',while the observation group received RIC treatment in addition to the control group's treatment,with a course of 14 d.The changes in National Institutes of Health Stroke Scale(NIHSS)scores and Barthel index(BI,daily living ability score table)on the day of admission and after 14 d of treatment,the changes in hematoma volume on computed tomography(CT)imaging,and the incidence of adverse events were compared between the two groups.Results At admission,the difference is not statistically significant in NIHSS scores,BI,and CT imaging hematoma volume between the two groups(P>0.05).After 14 d of treatment,the NIHSS scores of both groups were reduced compared to before treatment,and the scores of the observation group were lower than those of the control group(P<0.05);the BI of both groups was increased compared to before,and the scores of the observation group were higher than those of the control group(P<0.05);there were no significant differences in CT imaging hematoma volume and the incidence of adverse events between the two groups(P>0.05).Conclusion Continuous RIC treatment for 14 d is safe and well-tolerated in patients with spontaneous intracerebral hemorrhage and can effectively improve the neurological function of patients.

Acute symptomatic osteoporotic thoracolumbar compression fracture (ASOTLF) can lead to chronic low back pain, kyphosis deformity, pulmonary dysfunction, loss of mobility, and even life-threatening complications. Vertebral augmentation is currently the mainstream treatment method for this condition. In 2019, the Editorial Board of Chinese Journal of Trauma and the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association collaboratively led the development of Clinical guideline for vertebral augmentation for acute symptomatic osteoporotic thoracolumbar compression fractures. Six years later, with advances in clinical diagnosis and treatment techniques as well as accumulating evidence in related fields, the 2019 guideline requires updating. To this end, the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association, the Spinal Health Professional Committee of China Human Health Science and Technology Promotion Association, and the Minimally Invasive Orthopedics Professional Committee of Shaanxi Medical Doctor Association have organized experts in the field to develop the Clinical guideline for vertebral augmentation of acute symptomatic osteoporotic thoracolumbar compression fractures ( version 2025) , based on the latest evidence-based medical researches. This guideline incorporates 3 recommendations retained from the 2019 version with updated strength of evidence, along with 12 new recommendations. It provides recommendations from six aspects of diagnosis, pain management, treatment option selection, prevention of postoperative complications, anti-osteoporosis therapy, and postoperative rehabilitation, aiming to provide a reference for standard treatment of vertebral augmentation for ASOTLF in hospitals at all levels.

Inflammatory bowel disease (IBD) is an autoimmune disorder involving complex immune regulation, where balancing localized and systemic immunosuppression is a key challenge. This study aimed to enhance the therapeutic efficacy by engineering the probiotic Escherichia coli Nissle 1917 (EcN). We removed endogenous plasmids pMUT1 and pMUT2 from wild-type EcN and expressed the mPD-L1 (19‒238 aa)-mFc fusion protein on the bacterial surface using a cytolysin A (ClyA) fragment. This modification stabilized mPD-L1 (19‒238 aa) protein expression and promoted its recruitment to outer membrane vesicles (OMVs). The engineered strain, EcNΔ_pMUT1/2-ClyA-mPD-L1-mFc (EcN-ePD-L1-mFc), features conditional ePD-L1-mFc expression under the araBAD promoter, enhancing gut-targeted release and reducing systemic side effects. This strain improved treatment targeting and efficiency by enabling direct ePD-L1-mFc interaction with immune cells at inflammation sites. OMVs from this strain induced Treg proliferation, inhibited effector T cell proliferation in vitro, and significantly improved intestinal inflammation and colonic epithelial barrier repair in vivo. Additionally, the bacterium restored intestinal microbiota balance, increasing Lactobacillaceae and reducing Bacteroides. This study highlights the engineered bacterium's potential for targeted intestinal immune modulation and offers a novel local IBD treatment approach with promising clinical prospects.

ObjectiveTo reveal the mechanism of Zuogui Jiangtang Jieyu prescription against damage to hippocampal synaptic microenvironment via suppressing glutamate receptor 2 （GluR2）/Parkin signal-mediated mitophagy in rats with diabetes-related depression （DD）. MethodsEighty male SD rats underwent adaptive feeding for 5 days before the study. Ten rats were randomly assigned to the normal group. The model of DD rats was established with the rest by 2-week high-fat diet + streptozotocin （STZ） tail intravenous injection + 28 days of chronic unpredictable mild stress （CUMS） combined with isolation. The rats were randomly divided into a normal group， a model group， a GluR2 blocker group （5 μg·kg^-1）， a GluR2 agonist group （10 μg·kg^-1）， a metformin + fluoxetine group （0.18 g·kg^-1 metformin + 1.8 mg·kg^-1 fluoxetine）， and high- and low-dose Zuogui Jiangtang Jieyu prescription groups （20.52 and 10.26 g·kg^-1， respectively）. The rats in the GluR2 blocker group and the GluR2 agonist group were continuously injected with CNQX and Cl-HIBO in the dentate gyrus of the hippocampus once a week starting from stress modeling， respectively， while the metformin + fluoxetine group and the high- and low-dose Zuogui Jiangtang Jieyu prescription groups were continuously given intragastric administration for 28 d at the same time of stress modeling. Depression-like behavior was evaluated by open field and forced swimming experiments. The levels of serum insulin and adenosine triphosphate （ATP） in hippocampus were detected by biochemical analysis. The levels of 5-hydroxytryptamine （5-HT） and dopamine （DA） in hippocampus were detected by enzyme-linked immunosorbent assay （ELISA）. The autophagosomes of hippocampal neurons were observed by transmission electron microscopy. The morphology and structure of dendrites and spines of hippocampal neurons were evaluated by Golgi staining. Western blot detected the expression levels of GluR2 and Parkin proteins in hippocampus. The expression levels of GluR2， Parkin， regulating synaptic membrane exocytosis protein 3 （RIMS3）， and postsynaptic density protein 95 （PSD95） in the dentate gyrus of the hippocampus were detected by immunofluorescence. ResultsCompared with the normal group， the model group exhibited reduced total activity distance in the open field and increased immobility time in forced swimming （P<0.01）， lowered levels of serum insulin and ATP， 5-HT， and DA in hippocampus （P<0.01）， increased autophagosomes of hippocampal neurons， significantly damaged morphology and structure of dendrites and spines of hippocampal neurons， decreased expression levels of GluR2， RIMS3， and PSD95 in hippocampus， and an increased Parkin expression level （P<0.05， P<0.01）. Compared with the model group， the GluR2 blocker group and the GluR2 agonist group showed aggravation and alleviation of the above abnormal changes， respectively （P<0.05， P<0.01）. The above depression-like behavior was significantly improved in the high- and low-dose Zuogui Jiangtang Jieyu prescription groups to different degrees. Specifically， the two groups saw elevated levels of serum insulin and ATP， 5-HT， and DA in hippocampus （P<0.05， P<0.01）， restrained increase in autophagosomes and damage to morphology and structure of dendrites and spines of hippocampal neurons， up-regulated protein expression levels of GluR2， RIMS3， and PSD95， and down-regulated Parkin expression level （P<0.05， P<0.01）. ConclusionZuogui Jiangtong Jieyu prescription can ameliorate the mitophagy-mediated damage to hippocampal synaptic microenvironment in DD rats， the mechanism of which might be related to the regulation of GluR2/Parkin signaling pathway.
