The disturbance of the human microbiota influences the occurrence and progression of many diseases. Live therapeutic bacteria, with their genetic manipulability, anaerobic tendencies, and immunomodulatory properties, are emerging as promising therapeutic agents. However, their clinical applications face challenges in maintaining activity and achieving precise spatiotemporal release, particularly in the harsh gastrointestinal environment. This review highlights the innovative bacterial functionalized encapsulation strategies developed through advances in physicochemical and biological techniques. We comprehensively review how bacterial encapsulation strategies can be used to provide physical barriers and enhanced adhesion properties to live microorganisms, while introducing superior material properties to live bacteria. In addition, this review outlines how bacterial surface coating can facilitate targeted delivery and precise spatiotemporal release of live bacteria. Furthermore, it elucidates their potential applications for treating different diseases, along with critical perspectives on challenges in clinical translation. This review comprehensively analyzes the connection between functionalized bacterial encapsulation and innovative biomedical applications, providing a theoretical reference for the development of next-generation bacterial therapies.

Objective To analyze the relationship between serum microRNA(miR)-96-5p,miR-486-5p lev-els and inflammatory response and prognosis in patients with post-traumatic sepsis.Methods A total of 205 trauma patients who were admitted to the First Affiliated Hospital of Hainan Medical University from March 2019 to October 2022 were selected,patients were divided into sepsis group(77 cases)and non-sepsis group(128 cases)according to whether they progressed to sepsis during treatment.The relative expression levels of serum miR-96-5p and miR-486-5p in two groups were detected by real-time fluorescence quantitative PCR,and the levels of serum inflammatory factors[C-reactive protein(CRP),procalcitonin(PCT),interleukin-6(IL-6)]were detected.The correlation between serum miR-96-5p,miR-486-5p expression and inflammatory fac-tors in sepsis group were analyzed by Pearson correlation analysis.The prognosis of patients with post-trau-matic sepsis was further analyzed,patients were divided into the survival group and the death group according to the survival outcome during hospitalization.The influencing factors of death in patients with post-traumatic sepsis were analyzed by multivariate Logistic regression model,the value of miR-96-5p and miR-486-5p for predicting death of patients with post-traumatic sepsis were analyzed by receiver operating characteristic(ROC)curve.Results The relative expression level of serum miR-96-5p in sepsis group was lower than that in non-sepsis group(P<0.05),and the relative expression level of miR-486-5p was higher than that in non-sepsis group(P<0.05).The levels of serum CRP,PCT and IL-6 in sepsis group were higher than those in non-sepsis group(P<0.05).Pearson correlation analysis showed that the relative expression level of miR-96-5p in sepsis group was negatively correlated with the levels of CRP,PCT and IL-6(P<0.05),and the relative expression level of miR-486-5p was positively correlated with the levels of CRP,PCT and IL-6(P<0.05).A-mong 77 patients with post-traumatic sepsis,67 survived and 10 died.Multivariate Logistic regression analysis showed that the increase of the relative expression level of miR-96-5p was a protective factor for death in pa-tients with post-traumatic sepsis(P<0.05),and the increase of injury severity score(ISS)and the relative expression level of miR-486-5p were risk factors for death in patients with post-traumatic sepsis(P<0.05).The ROC curve showed that the area under the curve of the combined detection of ISS,miR-96-5p and miR-486-5p for death in post-traumatic sepsis patients was 0.860,and sensitivity and specificity were 0.900 and 0.821,respectively.The predictive efficacy of combined detection was higher than that of individual detection.Conclu-sion Serum miR-96-5p is lowly expressed and miR-486-5p is highly expressed in patients with post-traumatic sepsis,and the levels of inflammatory factors increase in the body.The expression of miR-96-5p and miR-486-5p is closely related to the inflammatory response,the two are also influencing factors for the death of patients and have certain predictive value for prognosis,and they could provide a reference basis for early clinical evalu-ation of the condition and prognosis.

Objective To compare the postoperative analgesic effect between serratus plane block and thoracic paravertebral block in patients undergoing thoracoscopic surgery.Methods Sixty patients undergoing thoracoscopic surgery, 38 males and 22 females, aged 18-65, BMI 18-25 kg/m2, falling into ASA physical status I or II.They were divided into groups S and T by random number table, 30 cases in each group.Two groups of patients were treated with general anesthesia with endobronchial intubation and PCIA after operation.Group S performed Ultrasound-guided serratus plane block and group T performed thoracic paravertebral block, 0.4％ropivacaine 30 ml were used in the two groups.The two groups of patients were observed 30 min after block, and the sensory block plane was measured with acupuncture and recorded.Recording operation time, onset time and duration of the block.Resting and cough VAS score were recorded at 2, 4, 8, 12, 24, and 48 hafter surgery.The first pressing time of the analgesic pump and times of press analgesic pump, the amount of sufentanil used and times the number of cases of useing piperidine were recorded within 48 hafter operation.Block related complications and analgesic related adverse reactions were recorded.Results Compared with group T, the operation time of the block obviously shortening but the duration obviously lengthening (P<0.01).Resting and cough VAS score at 12 hafter surgery significantly was lower (P<0.01).The first pressing time of the analgesic pump obviously lengthening, the number of press analgesic pump and the amount of sufentanil used significantly were reduced (P<0.01) in group S.Conclusion Ultrasound guided SP block and TPVB block can provide good postoperative analgesia for patients undergoing thoracoscopic surgery, but SP block is more durable, with less operation time and complications than TPVB block, and can effectively reduce the opioid demand and incidence of nausea and vomiting after operation.

Objective To investigate the effect of the compound administration of levobupiva-caine and magnesium sulfate in ultrasonography-guided femoral block on postoperative analgesia of anterior cruciate ligament reconstruction.Methods A total of 107 patients,66 males and 41 females, aged 25-60 years,ASA physical status Ⅰ or Ⅱ,undergoing arthroscopic anterior cruciate ligament (ACL)reconstruction,were randomly divided into magnesium sulfate group (n = 56 )and control group (n = 51 ).Both groups were treated with ultrasound-guided ipsilateral femoral nerve block before anesthesia induction.The patients in the magnesium sulfate group were treated with 0.25%levobupivacaine and 2% magnesium sulfate mixture 20 ml,and the control group was treated with 0.25% levobupivacaine 20 ml.The blocking of sensation and movement of femoral nerve was recor-ded.The VAS scores of resting and exercise were recorded at 4,6,12,24 and 48 h after operation. The additional analgesics,tramadol dosage,satisfaction score at postoperative 48 h,incidence of nau-sea and vomiting and other adverse reactions at 48 h after surgery were recorded.Results At postop-erative 12 h,VAS score was significantly lower in the magnesium sulfate group than that in the con-trol group (P <0.05).There were 5 cases (8.9%)needing additional analgesics in the magnesium sulfate group,significantly lower than 10 cases (19.6%)in the control group (P <0.05).The tram-adol dosage of magnesium sulfate group was significantly lower than that in the control group (P <0.05).The duration and onset time of sensation and movement block and Likert satisfaction score in the magnesium sulfate group were significantly superior to that of control group (P <0.05).The inci-dence of adverse reactions between the two groups were not statistically different.Conclusion The combined applications of levobupivacaine and magnesium sulfate in ultrasound-guided ipsilateral femo-ral nerve block could shorten the onset time and prolong the duration of blocking,improve the post-operative analgesic effect and patients' satisfaction, reduce the dosage of analgesic drugs. Additionally,it dose not increase the incidence of adverse reactions.

Aim To study the effects of Free Anthra-quinone from Rhubarb (FAR)on myocardial CTGF and collagen expression and interstitial fibrosis in dia-betic rats.Methods The male SD rats were randomly divided into normal group (CON),diabetic cardiomy-opathy group (DCM) and FAR treatment group (FAR).Streptozocin was intraperitoneally injected in-to the animals in the latter 2 groups to induce diabetic rat model.The model was expected to be stable for 2 weeks before the treatment.At the end of the 8th week in treatment,fasting plasma glucose and heart mass in-dex were measured.Masson staining was used to ob-serve the myocardial fibrosis.RT-PCR was used to de-tect the mRNA levels of CTGF,procollagen type Ⅰand collagen type Ⅲ.Immunohistochemical method was used to detect the content of CTGF.ELISA was used to detect the depositions of collagen type I and collagen type Ⅲ. Results Compared with CON group,fasting plasma glucose,heart mass index,the degree of myocardial fibrosis,and the expressions of CTGF,collagen type I and collagen type Ⅲ in left ven-tricular myocardial tissue of DCM group were signifi-cantly increased. However, compared with DCM group,fasting plasma glucose,heart mass index,the degree of myocardial fibrosis,and the expressions of CTGF,collagen type I and collagen type Ⅲ in left ven-tricular myocardial tissue of FAR-treated rats were sig-nificantly decreased.Conclusion FAR retards the process of myocardial fibrosis in diabetic rats by down-regulating the expression of CTGF,reducing the syn-thesis and depositions of collagen type I and collagen type Ⅲ.
