Objective:To understand the impact of diet on glycemic control in community-managed patients with type 2 diabetes mellitus (T2DM) and provide evidence for implementing prevention strategies and measures for diabetes patients.Methods:Eight communities were randomly selected from Changshu and Wuhan in 2015, and T2DM patients managed in the community were selected to conduct questionnaire surveys, physical measurements, and blood glucose testing. Factor analysis was used to obtain dietary patterns. A binary logistic regression model was used to analyze the factors affecting glycemic control.Results:Finally, 1 818 T2DM patients were included, and the control rate of FPG was 57.59% (95% CI: 55.30%-59.86%), and the control rate of 2 h postprandial blood glucose (2 h PBG) was 24.90% (95% CI: 22.93%- 26.91%). Five dietary patterns were obtained by factor analysis: animal food pattern, fruit-aquatic products-potato patterns, vegetable-grain pattern, egg-milk-bean pattern, and oil-salt patterns. No-conditional multivariate logistic regression analysis showed that after adjusting for confounding factors, the reduced probability of FPG control was related to animal food pattern ( OR=0.71, 95% CI: 0.52-0.98) and fruit-aquatic products-potato patterns ( OR=0.71, 95% CI: 0.51-0.97). The decrease in the 2 h PBG control probability was related to fruit-aquatic products-potato patterns ( OR=0.60, 95% CI: 0.40-0.90). The increased probability of FPG and 2 h postprandial glucose control were both related to vegetable-grain pattern ( OR=1.41, 95% CI: 1.03-1.94; OR=1.68, 95% CI: 1.13-2.51) and egg-milk-bean pattern ( OR=1.75, 95% CI: 1.25-2.46; OR=1.56, 95% CI: 1.00-2.42). Compared with the Q4 group of egg-milk-bean pattern, the FPG control rate of the combination of "fruit-aquatic products-potato pattern ( Q4 group), vegetable-grain pattern ( Q2 group), egg-milk-bean pattern ( Q3 group)" was higher ( OR=6.79, 95% CI: 1.15-40.23, P=0.035). Compared with the Q4 group of vegetable-grain pattern, the combination of "fruit-aquatic products-potato pattern ( Q4 group), vegetable-grain pattern ( Q3 group), egg-milk-bean pattern ( Q2 group), oil-salt pattern ( Q2 group)" had higher control rate of 2 h PBG ( OR=12.78, 95% CI: 1.26-130.05, P=0.031). Conclusions:A proper combination of dietary patterns and dietary patterns are more conducive to the control of FPG and 2 h PBG in T2DM patients managed in the communities of Wuhan and Changshu. Patient nutrition education should be strengthened, and the food-matching ability of patients should be improved.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

Objective: To examine the clinical feasibility of mixed reality navigation (MRN) technology based on multimodal imaging for the resection of intracranial eloquent lesions. Methods: Fifteen patients with intracranial eloquent lesions admitted to the Department of Neurosurgery, the First Medical Center, People's Liberation Army General Hospital from September 2020 to September 2021 were retrospectively enrolled. There were 7 males and 8 females, aged (50±16) years (range: 16 to 70 years). Postoperative pathological diagnosis included meningioma (n=7), metastatic carcinoma (n=3), cavernous hemangioma, glioma, ependymoma, aneurysmal changes and lymphoma (n=1, respectively). The open-source software was used to perform the three-dimensional visualization of preoperative images, and the self-developed MRN system was used to perform the fusion and interaction of multimodal images, so as to formulate the surgical plan and avoid damaging the eloquent white matter fiber tracts. Traditional navigation, intraoperative ultrasound and fluorescein sodium angiography were used to determine the extent of lesion resection. The intraoperative conditions of MRN-assisted surgery were analyzed, and the setup time and localization error of MRN system were measured. The changes of postoperative neurological function were recorded. Results: MRN based on multimodal imaging was achieved in all patients. The MRN system setup time (M(IQR)) was 36 (12) minutes (range: 20 to 44 minutes), and the localization error was 3.2 (2.0) mm (range: 2.6 to 6.7 mm). The reliability of eloquent white matter fiber tracts localization based on MRN was rated as "excellent" in 11 cases, "medium" in 3 cases, and "poor" in 1 case. There were no perioperative death and no new impairment in motor, language, or visual functions after operation. Transient limb numbness occurred in 1 patient after operation, and recovered to the preoperative state in 2 weeks after operation. Conclusion: The MRN system based on multimodal imaging can improve the surgical accuracy and safety, and reduce the incidence of iatrogenic neurological dysfunction.

Exosomes are lipid bilayer membranous vesicles actively secreted by various cells in the organism， which are like nanoparticles and have messenger targeting. Combining with the theory of supramolecular "Qi chromatography" of traditional Chinese medicine （TCM）， research ideas and strategies of modernization of TCM can be constructed. Exosomes are secreted by cells， and the membrane contains nucleic acids， proteins， lipids and small molecular metabolites and others， which can accurately coordinate the functions of each cell， concentrate and transmit the functional information of the parent cell， and is the concise form of reflecting cell functions. At the same time， it is loaded with the "imprinted templates" of the supramolecular "Qi chromatography" theory of TCM. If the "imprinted templates" carrying rules among the gene-protein-lipid-small molecules wrapped in it is studied， the modern experimental research ideas and strategies of TCM theory can be established for revealing the functions of the body's meridians and viscera. Firstly， the present situation of exosomes， including discovery， secretion， characteristics， functions， attribution， uptake， research methods and application status， were reviewed in this paper. And the natural properties of its precise messenger targeted delivery vehicle were elaborated， reflecting the operation law of microscopic substances in meridians and viscera. Secondly， to explore it as an important carrier of the concentrated "imprinted templates" of the supramolecular "Qi chromatography" theory of TCM， and integrating the research methods of exosomes and supramolecular chemistry of TCM， this paper proposes experimental research ideas and strategies on the microscopic material basis of meridians and viscera， compatibility of TCM compound， and targeting of TCM targeted preparations.

To investigate the potential toxic effects and mechanisms of Tris(1; 3-dichloro-2-propyl) phosphate (TDCIPP) on thyroid in female SD rats. Thirty-two 3-weeks-old female SD rats were randomly divided into normal group(treated with corn oil ), and low/moderate/high-dose group treated with TDCIPP (dissolved in corn oil )(n=8). All rats were treated with corn oil or TDCIPP (50, 100, 250 mg/(kg·d)) once a day during a 21-day period. All rats were sacrificed after the last administration. Serum thyroid stimulating hormone (TSH), 3,3',5-triiodothyronine (T3), 3,3',5,5'-tetraiodothyronine (T4), free 3,3',5,5'-tetraiodothyronine (FT4) were detected with ELISA kit. Morphology of thyroid was observed with hematoxylin and eosin (HE) staining. Expressions of genes and proteins correlate with thyroid were measured respectively by real-time fluorescence quantitative PCR and Western blot. Compared with control group, morphology of thyroid showed follicles irregular arrangement, hypocolloid, and follicular hyperplasia in TDCIPP treatment groups. The levels of serum TSH in low-dose TDCIPP group and T3 in high-dose TDCIPP group were significantly higher than those in control group(P＜0.05). Thyroid stimulating hormone receptor (TSHR) mRNA expression was decreased distinctly in low-dose TDCIPP group, while the expression of thyroperoxidase (TPO) mRNA was increased notably in moderate and high-dose TDCIPP groups(P＜0.05,P＜0.01). Compared with control group, the level of TRβ protein was decreased significantly in moderate and high-dose TDCIPP groups, while the expressions of udp-glucuronosyl-transferases (UGTs) and cytochrome-p450-3A1 (CYP3A1) proteins were upregulated notably in TDCIPP treatment groups(P＜0.05). Treated with 50 mg/(kg·d) TDCIPP can cause thyroid hyperplasia, change the levels of thyroid hormones, and disturb thyroid function, therefore, it has toxic effects on the thyroid.

We compared the pharmacokinetic and pharmacodynamic profiles of desmopressin acetate after intraocular, intravenous and intragastric administration in rabbits to better understand the systemic delivery of peptide drugs through intraocular administration. Fifteen rabbits were randomly divided into three groups (intraocular administration, 7 μg·kg^-1; intravenous administration, 0.7 μg·kg^-1; and intragastric administration, 7 μg·kg^-1). Blood samples were taken from the heart at predetermined time points after dosing and the plasma desmopressin concentration was analyzed by enzyme-linked immunosorbent assay (ELISA). Another 21 rabbits were randomly divided into three groups (intraocular administration, 7 μg·kg^-1; intravenous administration, 0.7 μg·kg^-1; intragastric administration, 7 μg·kg^-1) for a pharmacodynamics study. Urine was collected at predetermined intervals after dosing. The pharmacokinetic parameters after intravenous administration were as follows: C_max was 143.0 pg·mL^-1; the area under the plasma concentration–time curve for desmopressin (AUC_0-t) was 999.9 pg·h·mL^-1. The pharmacokinetic parameters after intraocular administration were as follows: t_max was 5 min, C_max was 125.6 pg·mL^-1, AUC_0-t was 873.1 pg·h·mL^-1, and absolute bioavailability (F) was 8.7%. The pharmacokinetic parameters after intragastric administration were as follows: t_max was 10 min, C_max was 104.1 pg·mL^-1, AUC_0-t was 451.8 pg·h·mL^-1, and absolute bioavailability was 4.5%. Intraocular administration and intravenous administration of one tenth of the dosage showed a similar effect, and the urine volume remained decreased for 12 h, but urine volume increased significantly in the second collection period after intragastric administration, and there was no decrease in volume 12 h after dosing. This study demonstrates that peptide drugs such as desmopressin can be absorbed more rapidly after intraocular administration than after intragastric administration and can exert systemic therapeutic effects. In this study, the program of animal testing had been approved by the Laboratory Animal Care and Use Committee at Anhui University of Chinese Medicine.

Objective: Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear. Methods: A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients' medical records. Multivariable logistic regression models were used to estimate the odds ratio ( Results: Overall, 158 (13.6%) patients were diagnosed with severe illness and 32 (2.7%) had unfavorable outcomes. Hypertension (2.87, 1.30-6.32), type 2 diabetes (T2DM) (3.57, 2.32-5.49), cardiovascular disease (CVD) (3.78, 1.81-7.89), fatty liver disease (7.53, 1.96-28.96), hyperlipidemia (2.15, 1.26-3.67), other lung diseases (6.00, 3.01-11.96), and electrolyte imbalance (10.40, 3.00-26.10) were independently linked to increased odds of being severely ill. T2DM (6.07, 2.89-12.75), CVD (8.47, 6.03-11.89), and electrolyte imbalance (19.44, 11.47-32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission (5.46, 3.25-9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes (6.58, 1.46-29.64) within two weeks. Conclusion Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes.

Background::Previous studies have provided conflicting evidence about the increased overall survival (OS) in lung cancer patients with diabetes mellitus (DM) compared with those without DM. This study assessed progression-free survival (PFS)/OS in lung cancer patients with or without DM and tentatively analyzed the impact of blood glucose levels on PFS/OS in lung cancer patients.Methods::Data were collected from lung cancer patients based upon admission records from January 2010 to January 2012 and follow-up records from January 2010 to January 2015 in the Department of Pulmonary Medicine, Zhongshan Hospital, Fudan University, Shanghai. The data included patient sex, age, body mass index (BMI), smoking status, history of DM, level of blood glucose, pathological type, clinical stage of cancer, chemotherapy regimen, and history of anti-DM drugs. The Cox regression model and Kaplan-Meier method were used for the analysis of hazard factors and PFS/OS. For comparison of PFS/OS in lung cancer with or without DM, patients were divided into three groups: lung cancer with DM, lung cancer without DM but with elevated level of blood glucose, lung cancer without DM or elevated level of blood glucose.Results::In total, the data from 200 lung cancer patients (138 males/62 females, aged 29.0 to 78.0 years, mean 60.0 ± 8.6 years) were collected. For the comparison of PFS/OS in lung cancer patients with or without DM, patients were divided into three groups: lung cancer with DM ( n = 31); lung cancer without DM but with elevated levels of blood glucose ( n = 40); and lung cancer without both DM and elevated levels of blood glucose ( n = 128), whereas 1 patient dropped out of the study. All the patients underwent complete chemotherapy and were followed up for 36.0 to 60.0 months. Kaplan-Meier survival analysis showed that lung cancer patients with DM had increased PFS and OS compared with those without DM (log-rank, P < 0.05, P < 0.01); the median PFS in lung cancer with DM was 12.0 months (95% confidence interval [CI], 4.0-16.0) vs. 6.0 months in those without DM (95% CI, 5.8-6.3); and the median OS in lung cancer patients with DM was 37.0 months (95% CI, 29.0-46.6) vs. 12.0 months in those without DM (95% CI, 10.9-13.1). For the other two groups of patients without DM, there was a trend toward a shorter PFS and OS in patients with elevated blood glucose compared with those without elevated blood glucose. Cox regression showed that PFS in lung cancer patients was favorably associated with the usage of anti-DM drugs, BMI, clinical stage of cancer, and chemotherapy regimen (all P < 0.05) but was inversely associated with the level of blood glucose ( P < 0.05). Conclusions::Lung cancer patients with DM have prolonged PFS and OS compared with those without DM, and the level of blood glucose was inversely associated with PFS. The current results indicate that PFS may be a meaningful intermediate endpoint for OS and that the levels of blood glucose hopefully represent a prognostic factor in lung cancer patients.
