OBJECTIVE: To evaluate the impact of sutureless approach to the dorsal venous complex (DVC) combined with robotic-assisted laparoscopic prostatectomy on sexual function of patients with prostatic cancer. METHODS: This study included 114 prostate cancer patients who underwent robot-assisted laparoscopic radical prostatectomy at our hospital from January 2021 to January 2024. The patients were randomly divided into a control group (n=57) and an observation group (n=57). The control group received conventional "figure-of-eight" suture ligation of the dorsal venous complex (DVC), while the observation group underwent direct DVC transection using monopolar electrocautery scissors after increasing pneumoperitoneum pressure.Surgical duration, intraoperative blood loss, positive surgical margin rates, and positive apical margin rates were recorded. The continence rates and rates of morning erections at 1, 3 and 6 months after the operation were compared between groups. Sexual function was assessed pre-operatively and at 6 months post-operation by using the IIEF-5 and PEDT. RESULTS: The operative time in the observation group was significantly longer than that in the control group (［115.71 ± 19.42］ min vs ［103.42 ± 12.78］ min， P<0.05). While no significant differences were observed in intraoperative blood loss, positive surgical margin rate, or positive apical margin rate between the two groups (P>0.05). At 3 and 6 months after the operation, the observation group exhibited higher urinary continence rates and morning erection recovery rates compared to the control group （P<0.05). Furthermore, at 6 months postoperatively, the observation group demonstrated significantly higher IIEF-5 scores and lower PEDT scores than those of control group(P<0.05). CONCLUSION The use of a sutureless DVC technique in robotic-assisted laparoscopic radical prostatectomy protects the post-operative sexual function in patients.

OBJECTIVE: To investigate the effectiveness of Xuanshen Yishen Decoction (XYD) in the treatment of hypertension. METHODS: Hospital electronic medical records from 2019-2023 were utilized to emulate a randomized pragmatic clinical trial. Hypertensive participants were eligible if they were aged ⩾40 years with baseline systolic blood pressure (BP) ⩾140 mm Hg. Patients treated with XYD plus antihypertensive regimen were assigned to the treatment group, whereas those who followed only antihypertensive regimen were assigned to the control group. The primary outcome assessed was the attainment rate of intensive BP control at discharge, with the secondary outcome focusing on the 6-month all-cause readmission rate. RESULTS: The study included 3,302 patients, comprising 2,943 individuals in the control group and 359 in the treatment group. Compared with the control group, a higher proportion in the treatment group achieved the target BP for intensive BP control [8.09% vs. 17.5%; odds ratio (OR)=2.29, 95% confidence interval (CI)=1.68 to 3.13; P<0.001], particularly in individuals with high homocysteine levels (OR=3.13; 95% CI=1.72 to 5.71; P<0.001; P for interaction=0.041). Furthermore, the 6-month all-cause readmission rate in the treatment group was lower than in the control group (hazard ratio=0.58; 95% CI=0.36 to 0.91; P=0.019), and the robustness of the results was confirmed by sensitivity analyse. CONCLUSIONS XYD could be a complementary therapy for intensive BP control. Our study offers real-world evidence and guides the choice of complementary and alternative therapies.

OBJECTIVE: Several epidemiological observational studies have related particulate matter (PM) exposure to Inflammatory bowel disease (IBD), but many confounding factors make it difficult to draw causal links from observational studies. The objective of this study was to explore the causal association between PM _2.5 exposure, its absorbance, and IBD. METHODS: We assessed the association of PM _2.5 and PM _2.5 absorbance with the two primary forms of IBD (Crohn's disease [CD] and ulcerative colitis [UC]) using Mendelian randomization (MR) to explore the causal relationship. We conducted two-sample MR analyses with aggregated data from the UK Biobank genome-wide association study. Single-nucleotide polymorphisms linked with PM _2.5 concentrations or their absorbance were used as instrumental variables (IVs). We used inverse variance weighting (IVW) as the primary analytical approach and four other standard methods as supplementary analyses for quality control. RESULTS: The results of MR demonstrated that PM _2.5 had an adverse influence on UC risk (odds ratio [ OR] = 1.010; 95% confidence interval [ CI] = 1.001-1.019, P = 0.020). Meanwhile, the results of IVW showed that PM _2.5 absorbance was also causally associated with UC ( OR = 1.012; 95% CI = 1.004-1.019, P = 0.002). We observed no causal relationship between PM _2.5, PM _2.5 absorbance, and CD. The results of sensitivity analysis indicated the absence of heterogeneity or pleiotropy, ensuring the reliability of MR results. CONCLUSION Based on two-sample MR analyses, there are potential positive causal relationships between PM _2.5, PM _2.5 absorbance, and UC.

Objective To explore the clinical characteristics and treatment scheme of periprosthetic joint infection(PJI)caused by Cutibacterium avidum(C.avidum).Methods The diagnosis and treatment process of a patient with PJI caused by C.avidum was summarized,and relevant literatures in the database were retrieved for review.Results A 65-year-old female patient with body mass index(BMI)of 31.1 kg/m2 underwent left humeral head prosthesis replacement surgery following a left proximal humerus fracture.Ten months after the surgery,the pa-tient exhibited poor wound healing and oozing,along with limited movement of the left shoulder joint,and was diag-nosed infection following shoulder arthroplasty.Patient underwent debridement of the infected lesion and removal of the prosthesis.The tissue,bone cement and prosthesis were cultured for C.avidum.Four literatures were re-trieved and screened,a total of 30 patients with PJI(28 cases hip joint infection and 2 cases shoulder joint infection)caused by C.avidum were reported through literature retrieval,and 78.6％(n=22)total hip arthroplasty(THA)surgeries were performed using direct anterior approach(DAA).The positive rate of preoperative joint fluid culture was 71.4％,29 cases underwent surgical combined with sensitive antimicrobials treatment.Except for one patient who had repeated infection and underwent three surgeries,other patients had a good prognosis.Conclusion PJI caused by C.avidum is mostly seen in THA patients who are obese and undergo DAA,with a few cases reported after shoulder arthroplasty.The high sensitivity of preoperative joint fluid culture provides an important basis for the development of surgical strategies and anti-infection protocols.

Plant natural products have a wide range of pharmacological properties, not only can they be used as plant dietary supplements to meet the nutritional needs of the human body in the accelerated pace of life, but also occupy an important position in the research and development of therapeutic drugs for the treatment of tumors, inflammation and other diseases, and have been widely accepted by the public due to their good safety. However, despite the above advantages of plant natural products, limiting factors such as low solubility, poor stability, lack of targeting, high toxicity and side effects, and unacceptable odor have greatly impeded their conversion to clinical applications. Therefore, the development of new avenues for the application of new natural products has become an urgent problem to be solved at present. In recent years, with the continuous development of research, various strategies have been developed to improve the bioavailability of natural products. Among them, nanocarrier delivery system is one of the most attractive strategies at present. In past studies, a large number of nanomaterials (organic, inorganic, etc.) have been developed to encapsulate plant-derived natural products for their efficient delivery to specific organs and cells. Up to now, nanotechnology has not only been limited to pharmaceutical applications, but is also competing in the fields of nanofood processing technology and nanoemulsions. Among the various nanocarriers, liposomes are the largest nanocarriers with the largest market share at present. Liposomes are bilayer nanovesicles synthesized from amphiphilic substances, which have advantages such as high drug loading capacity and stability. Attractively, the flexible surface of liposomes can be modified with various functional elements. Functionalized modification of liposomes with different functional elements such as antibodies, nucleic acids, peptides, and stimuli-responsive moieties can bring out the excellent drug delivery function of liposomes to a greater extent. For example, the modification of functional elements with targeting function such as nucleic acids and antibodies on the surface of liposomes can deliver natural products to the target location and improve the bioavailability of drugs; the modification of stimulus-responsive groups such as photosensitizers, magnetic nanoparticles, pH-responsive groups, and temperature sensitizers on the surface of liposomes can achieve controlled release of drugs, localized targeting, and synergistic thermotherapy. In addition to the above properties, by using functionalized liposomes to encapsulate natural products with irritating properties can also effectively mask the irritating properties of natural products, improve public acceptance, and increase the possibility of application of irritating natural products. There are various strategies for modifying liposomes with functional elements, and the properties of functionalized liposomes constructed by different construction strategies differ. The commonly used construction strategies for functionalized liposomes include covalent modification and non-covalent modification. These two types of construction strategies have their own advantages and disadvantages. Covalent modification has better stability than non-covalent modification, but its operation is cumbersome. With the above background, this review focuses on the three typical problems faced by plant natural products at present, and summarizes the specific applications of functionalized liposomes in them. In addition, this paper summarizes the construction strategies for building different types of functionalized liposomes. Finally, this paper will also review the opportunities and challenges faced by functionalized liposomes to enter clinical therapy, and explore the opportunities to overcome these problems, with a view to better realizing the precise control of plant nanomedicines, and providing ideas and inspirations for researchers in related fields as well as relevant industrial staff.

Objective:To explore the differences in dynamic spontaneous brain activity in individuals with subjective cognitive decline (SCD) and its correlation with spatial navigation ability in SCD subjects.Methods:A total of 72 SCD subjects(SCD group) and 67 normal controls (NC group) matched for age, gender and education level were recruited from September 2020 to February 2023 at the Affiliated Drum Tower Hospital, Medical School of Nanjing University. All participants underwent resting-state functional magnetic resonance imaging (rs-fMRI) examinations, spatial navigation tests and cognitive function assessments. The rs-fMRI time series were segmented using a sliding time window method, and statistical analyses were carried out using SPSS 26.0 software to compare the differences in the dynamic amplitude of low frequency fluctuation (dALFF) between the two groups. Correlation analysis was conducted between dALFF values in different brain regions and scale scores and spatial navigation tests.Results:Compared with the NC group, the dALFF variability in the right precuneus(0.119±0.021, 0.130±0.031) and left cuneus(0.143±0.034, 0.156±0.032) in SCD group decreased ( t=-3.41, -3.12, P<0.05, FDR corrected), and the dALFF variability in the right middle occipital gyrus(0.146±0.023, 0.137±0.020) and right angular gyrus(0.148±0.025, 0.139±0.026) increased ( t=4.51, 3.36, both P<0.05, FDR corrected). The temporal variability of dALFF in the right precuneus in SCD group was negatively correlated with egocentric spatial navigation ( r=-0.341, P=0.025), delayed allocentric spatial navigation ( r=-0.286, P=0.035) and memory function ( r=-0.332, P=0.009). The temporal variability of dALFF in the left middle occipital gyrus was positively correlated with language function ( r=0.339, P=0.015) and visuospatial function ( r=0.343, P=0.008) in SCD group. Conclusions:The temporal variability of dALFF in the right precuneus and the left middle occipital gyrus may be the neurobiological basis of cognitive decline and spatial navigation impairment in SCD subjects, and it can be used as a potential imaging marker for early identification of SCD patients.

Objective To investigate the effect of evodiamine on renal fibrosis in rats with chronic renal failure(CRF)by regulating sphingosine kinase 1(SphK1)/S1P signaling pathway.Methods CRF rat model was established by feeding 0.5％adenine diet.The rats after modeling were randomly divided into model group,evodiamine low-and high-dose groups,Niaoduqing Granules group and evodiamine high-dose+K6PC-5(SphK1 activator)group.At the end of intervention,the levels of 24-hour urinary protein(24 h-UTP),serum urea nitrogen(BUN)and serum creatinine(SCr)were detected.The levels of monocyte chemoattractant protein 1(MCP-1)and interleukin 6(IL-6)in serum of rats were detected by enzyme-linked immunosorbent assay(ELISA).The pathological changes of renal tissue and collagen volume fraction(CVF)were observed by hematoxylin-eosin(HE)and Masson staining.The mRNA expressions of transforming growth factor β1(TGF-β1)and type Ⅳcollagen(COL-Ⅳ)in renal tissue were detected by real-time quantitative polymerase chain reaction(qRT-PCR).The protein expressions of SphK1 and S1P in renal tissue were detected by Western Blot.Results Compared with the normal group,the model group showed obvious inflammatory infiltration and collagen fiber deposition,the number of glomeruli decreased in renal tissue,and the expression levels of SCr,BUN,24h-UTP,IL-6,MCP-1,CVF,mRNA expressions of TGF-β1 and COL-Ⅳ,protein expessions of SphK1 and S1P were significantly increased(P＜0.05).Compared with the model group,the histopathological changes of the low-dose and high-dose evodiamine groups and the Niaoduqing Granules group was improved,and the expression levels of SCr,BUN,24 h-UTP,IL-6,MCP-1,CVF,mRNA expressions of TGF-β1 and COL-Ⅳ,protein expessions of SphK1 and S1P were significantly decreased.For intergroup comparison of each index,there were differences between the low-dose evodiamine group and the high-dose evodiamine group(P＜0.05),but there was no significant difference between the high-dose evodiamine group and the Niaoduqing Granules group(P＞0.05).Compared with the high-dose evodiamine group,the histopathological changes of the high-dose evodiamine+K6PC-5 group was further aggravated,and the improvement effect of all indexes were reversed(P＜0.05).Conclusion Evodiamine improves renal fibrosis in CRF rats by inhibiting SphK1/S1P signaling pathway.

Remazolam is a γ-aminobutyric acid(GABA)receptor agonist.It is a short-acting benzodiazepine drug that has just been launched in China in recent years.Its mechanism of action is to enhance inhibitory neurotransmitters of GABA in the central nervous system.It has been widely used in clinical practice for sedation,hypnosis,anti anxiety,and the treatment of insomnia.Meanwhile,remazolam is mainly used for induction and maintenance of general anesthesia during the perioperative period,with a fast onset time and a brief duration of action.Recent studies have shown that remazolam can protect important organs and alleviate organ damage by reducing inflammatory responses and oxidative stress,regulating cell apoptosis,and other pathways.This article summarizes the protective effects and mechanisms of remazolam on the brain,heart,liver,and lung,providing a theoretical basis for the clinical application of remazolam.

Postoperative cognitive dysfunction(POCD)is one of the common complications in the perioperative period,and it has a high incidence in elderly patients,and the large production of neuroinflammatory factors under surgical stimulation is the main cause of postoperative POCD.As an ultra-short-acting benzodiazepine of γ-aminobutyric acid receptor agonist,remimazolam can play a sedative-hypnotic and anxiolytic role in clinical practice,and can reduce inflammatory factors in the central nervous system and improve postoperative cognitive dysfunction by inhibiting neuroinflammatory response and oxidative stress.This article reviews the protective effect and mechanism of remimazolam on postoperative cognitive function,so as to provide a basis for the clinical use of remimazolam.

Excessive sodium/salt intake is the leading dietary risk factor for the loss of healthy life in the Chinese population. The "Healthy China 2030" Action Plan set the goal of reducing salt intake by 20% by 2030. However, salt intake in China is still at a very high level in the world, with adults reaching 11 g/d, more than twice the recommended limit of 5 g/d. The current policies and action plans of China have targeted catering workers, children, adolescents, and home chefs in salt, oil, and sugar reduction actions. However, there are still obvious deficiencies in the coordinated promotion and implementation. This study, therefore, proposed a set of comprehensive strategies (named CHRPS that is composed of communication and education, salt reduction in home cooking, salt reduction in restaurants, reducing salt content in pre-packaged food, and surveillance and evaluation) and key implementation points for further deepening the salt reduction action in China. These strategies were developed based on the main sources of dietary sodium for Chinese residents, the status of "knowledge, attitude and practice" in salt reduction, evidence of effective intervention measures, existing policies and requirements, and the salt reduction strategies of the World Health Organization and experience from some other countries. As a scientific reference, the CHRPS strategies will help the government and relevant organizations quickly implement salt reduction work and facilitate the earlier realization of China's salt reduction goal.
