Starting from the intrinsic relationship between the glymphatic system and the core pathogenesis of vascular cognitive impairment (VCI), including internal dampness, phlegm turbidity, and blood stasis, this paper explores clinical approaches to the diagnosis and treatment of VCI. Dysfunction of the kidney's role in governing water leads to the accumulation of dampness, phlegm turbidity, and blood stasis, which are key pathological mechanisms underlying the onset and progression of VCI. The glymphatic system participates in the circulation of cerebrospinal fluid within the central nervous system, and its impairment can result in reduced clearance of soluble metabolic waste products in the brain, a crucial factor contributing to VCI. It is proposed that the "kidney governing water" function is related to the glymphatic system, and that the cerebral collaterals correspond structurally to the glymphatic pathways. Clinically, therapies aimed at tonifying the kidney, resolving phlegm, activating blood circulation, and unblocking collaterals, such as modified Kaixin Powder (开心散), which eliminates dampness and turbidity, transforms phlegm, restores consciousness, enhances cognition, and strengthens the brain, are commonly employed. These treatments may improve VCI prognosis by regulating glymphatic system function, providing a theoretical basis for the prevention and treatment of VCI with traditional Chinese medicine.

Alzheimer's disease (AD) is an age-related neurodegenerative disease that belongs to the category of dementia in traditional Chinese medicine (TCM). According to the TCM theory, phlegm, dampness, stasis, and toxin are the major factors inducing the occurrence and development of AD. The application of aromatic Chinese medicines to remove the combined phlegm, dampness, stasis, and toxin is an important TCM method for treating AD. Aquaporins (AQPs) are involved in the water metabolism of the central nervous system (CNS), playing a role in the water balance of CNS. Therefore, AQPs are deeply involved in the occurrence and development of AD. AQPs may be the key targets of a variety of aromatic Chinese medicines. From the intrinsic relationship between AQPs and AD-inducing factors (phlegm, dampness, stasis, and toxin), this study explores the modern medical connotation of treating AD with aromatic Chinese medicines, aiming to provide ideas for the prevention and treatment of AD with TCM.

To analyze the prevalence, genomic characteristics and clinical relevance of carbapenem-resistant bacteria in untreated hospital wastewater, and to provide a reference basis for in-hospital assessment of public health situation and prevention of cross-infection. In March 2023, untreated wastewater in the wastewater treatment station of the Second Affiliated Hospital of Soochow University and wastewater in the U-shaped wastewater pipes of the hand-washing sinks in 26 wards were collected, centrifuged and diluted, and the drug-resistant bacteria were isolated by using LB solid plates containing meropenem (2 μg/ml) for species identification, drug sensitivity analysis, carbapenenase gene PCR detection and whole genome sequencing. The genome sequence was identified for drug resistance genes. Retrospective research was used, combining multilocus sequence typing (MLST) and single nucleotide polymorphism (SNP) analysis, to compare their homology with clinical isolates of the same quarter. The results showed that 56 carbapenem-resistant gram-negative bacteria were isolated from hospital wastewater, originating from 13 genera, of which 17 were isolated from the total hospital wastewater, with Aeromonas spp. as the most dominant genus (35.3%, 6/17), and 39 were isolated from the wastewater of 17 wards, with Pseudomonas spp. as the most dominant genus (30.8%, 12/39). All common wastewater isolates from our hospital were multidrug-resistant bacteria, with up to 100% resistant to some second-and third-generation cephalosporins. A total of 8 carbapenemase genes originated from wastewater isolates, including blaKPC, blaNDM, blaIMP, blaVIM, blaIND, blaOXA-58-like, blaOXA-48-like, and blaOXA-427-like. 39 wastewater isolates carried the carbapenemase genes, and the total wastewater of the hospital carried the highest isolation rate of blaKPC-2 bacteria (35.3%, 6/17) and the highest isolation rate of blaIMP-8 bacteria (31.8%, 7/22) were found in the wastewater from 26 wards. 14 wastewater isolates were found to carry both carbapenemase genes, with a total of 6 combinations. A new blaIMP-101 isoform was also identified for the first time. 4 wastewater isolates and 11 clinical isolates were screened for inclusion in the SNP analysis, in which only 15 SNPs differed between the two strains of ST11 Klebsiella pneumoniae of clinical and wastewater origin, which was highly homologous. In conclusion, the presence of multiple multi-drug resistant conditionally pathogenic bacteria in untreated hospital wastewater has the potential risk of spreading drug-resistant genes in the environment. The highly homologous Klebsiella pneumoniae isolated from hospital wastewater and clinics indicates the close association between hospital wastewater and clinical infections. Hospitals need to strengthen the monitoring of drug-resistant bacteria and drug-resistant genes in the wastewater environment, to prevent the widespread dissemination of drug-resistant bacteria and drug-resistant genes in hospital wastewater and to prevent nosocomial infections caused by drug-resistant bacteria in wastewater.

Objective:To observe the clinical efficacy of autologous platelet rich gel (APG) in the treatment of type 2 diabetic foot (DF) patients and the effect of APG on the expression of metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) in peripheral blood mononuclear cells (PBMCs).Methods:A total of 62 patients with DF admitted to the Affiliated Hospital of Kangda College of Nanjing Medical University from February 2021 to May 2022 were randomly divided into a control group (30 cases) and an observation group (32 cases) using a random number table method. The control group received ultrasound debridement and dressing change treatment, while the observation group received ultrasound debridement combined with APG treatment. After 6 weeks of treatment, the effective rate, transcutaneous oxygen partial pressure (TcPO 2), and serum tumor necrosis factor- α (TNF-α), interleukin-6 (IL-6), vascular endothelial growth factor (VEGF), hypoxia inducible factor α (HIF-1 α)and the level of MALAT1 expression in PBMCs of the two groups of patients were observed. The Pearson correlation analysis was used to investigate the relationship between the expression change of MALAT (△ MALAT1) and the total effective rate of treatment. Results:The total effective rate of the observation group was higher than that of the control group [93.75%(30/32) vs 73.33%(22/30), P<0.05]. After treatment, the systolic blood pressure (SBP), diastolic blood pressure (DBP), cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), fasting blood glucose (FPG), glycosylated hemoglobin (HbA 1c), urinary microalbumin/creatinine (UACR), uric acid (UA), white blood cells (WBC), TNF- α and IL-6 of both groups had decreased compared to before; HIF-1 α, VEGF and MALAT1 increased compared to before treatment (all P<0.05); After treatment, there was a statistically significant difference in UA, HIF-1α, VEGF, and MALAT1 between the observation group and the control group (all P<0.05). Pearson correlation analysis showed that Δ MALAT1 in DF patients was negatively correlated with TNF -α ( r=-0.61, P=0.02), IL-6 ( r=-0.52, P=0.04), WBC ( r=-0.53, P=0.03), and positively correlated with VEGF ( r=0.58, P=0.03) and HIF-1α ( r=0.54, P=0.03). The total effective rate of DF treatment was higher in the high change group of△ MALAT [88.37%(38/43) vs 73.68%(14/19), P<0.05]. There was no statistically significant difference in the incidence of adverse reactions between the two groups ( P>0.05). Conclusions:APG can significantly upregulate the expression of MALAT, improve wound tissue blood perfusion, wound angiogenesis, and inflammatory response, promote ulcer healing, and changes in MALAT expression can help determine the prognosis of DF.

The traditional-immunological strategies for clinical laboratories often rely on large and expensive instruments and skilled operators, and the measurement time is also long. However, the sensitivity of these strategies is still unsatisfactory. It is urgent to research and develop the point-of-care testing (POCT) featured as a highly sensitive, accurate, and rapid/POCT diagnosis. The Microfluidic chips have multi-advantages that are suitable for the clinical POCT diagnosis: high sensitivity, throughput, and automation. Recently, the Microfluidic-immune chips developed based on the microfluidic technology combined with immune detection have considered not only hotspots in the related research but also benefit to the tumor marker detection, antigen and antibody detection of infectious diseases, autoantibody detection, hormone detection, and other fields. However, there are still many challenges to be overcome during the application of chips, such as more effective microfluidic manipulation, more sensitive collection, and analysis of reaction signals.

The morbidity of scoliosis in adolescents in China is about 3%-5%, 80%-85% of the patients are adolescent idiopathic scoliosis (AIS), whose etiology is unknown. Scoliosis is a structural spine disease occurring during puberty or before skeletal maturation. Scoliosis has a greatly negative impacton not only the growth and development of adolescent spine, but also the mental health of adolescents. Ocular disease is a common clinical disease in which the eye ball and its accessory structures have structural abnormalitiesordys function. Ocular disease snotonly bring in convenience to patients's life, but also may induce diseases in other organs. Recent studies have shown that various ocular diseases may have a potential impact on scoliosis, and quite a fewof patients with certain ocular diseases have higher incidence rate of scoliosis. Therefore, in this article, the etiological relationship between eye diseases and scoliosis will be summarized, which provides guidance and direction for the etiological research of scoliosis and eye diseases. After sorting out, we found that the relationship between ophthalmic diseases and scoliosis mainly concentrated in the following four aspects: choroidal thickness and scoliosis, Goldenhar syndrome, gene level and strabismus. Among them, the genetic relationship is the most complex, about 40 kinds of gene or chromosome abnormalities have been found to cause ocular diseases and scoliosis; Goldenhar syndrome, also known as oculo-auriculo-vertebral spectrum, first revealed the relationship between ocular diseases and scoliosis, but the current statistical relationship is still very vague. There are few studies on choroidal thickness and strabismus at home and abroad, which are statistical studies, only revealing the relationship between choroidal thickness and scoliosis, and there are many defects in the study of choroidal thickness, which need further research.
