OBJECTIVE To evaluate the long-term cost-effectiveness of canagliflozin or semaglutide in patients with type 2 diabetes mellitus（T2DM）poorly controlled with metformin. METHODS Based on the perspective of China’s health system， a Markov model was used to calculate the long-term costs and utilities of canagliflozin or semaglutide combined with metformin for T2DM patients in China for 30 years based on the data from SUSTAIN 8 study. The incremental cost-effectiveness ratio（ICER） and incremental net monetary benefit （INMB） were calculated using one time the 2024 per capita gross domestic product（GDP） as the willingness-to-pay（WTP） threshold. One-way sensitivity analysis， probability sensitivity analysis and scenario analysis were conducted to confirm the stability of the conclusions. RESULTS Compared with canagliflozin + metformin， ICER of semaglutide combined with metformin was 260 485.67 yuan/quality-adjusted life year （QALY），which was higher than the WTP threshold set in this study （95 749 yuan/QALY），and the corresponding INMB was －61 576.24 yuan，indicating that the canagliflozin + metformin regimen was more cost-effective. The cost of diabetes without complications treatment in the semaglutide + metformin group had the greatest influence on INMB，but changes in parameters within the selected range did not drive decision reversal. With the increasing of WTP threshold，the economic acceptability of semaglutide + metformin regimen increased. Under the current WTP threshold，the annual cost of semaglutide should be reduced by 42.95% to make the semaglutide + metformin regimen more cost- effective. CONCLUSIONS From the perspective of China’s health system， canagliflozin + metformin is more cost-effective than semaglutide + metformin for T2DM patients yueru. with poor glycemic control with metformin alone.

Objective:To evaluate the utility of the Rapid Axial Roll Test （RART）, Supine Roll Test （SRT）, and Lying-Down Test （LDT） in determining the affected semicircular canal in cases of horizontal semicircular canal benign paroxysmal positional vertigo （HSC-BPPV）. Methods:A total of 330 patients diagnosed with HSCBPPV from September 2022 to September 2023 were collected and divided into three groups based on the different positional tests received: ①SRT Group, ②LDT+SRT Group, ③RART+SRT Group. The trial was divided into two stages: LDT/RART for patients in the first stage, and SRT for patients in the second stage. The elicitation rate of nystagmus among the three groups was compared to evaluate the accuracy in determining the affected semicircular canal in HSCBPPV. Results:Nystagmus was elicited in 84.55% （279/330） of the patients by positional tests. The elicitation rate of nystagmus in the RART+SRT/LDT group was 94.55% （104/110）, in the LDT+SRT group it was 84.11% （90/107）, and in the SRT group it was 69.91% （79/113）. The differences among the three groups were statistically significant （χ²= 23.88, P<0.001）. In the ② and ③ groups, there was a statistically significant difference in the elicitation rate of nystagmus between stage Ⅰ （patients with LDT or RART） （χ²=43.842, P<0.001）. SRT was performed in the stage Ⅱ, and there was a statistically significant difference in nystagmus extraction rate between the two groups （χ² =4.690, P=0.030）. The difference in the proportion of agreement between stage Ⅰ（LDT or RART） and stageⅡ （SRT） in determining the affected side of the semicircular canal was also statistically significant （χ² =40.502, P<0.001）. For patients with a consistent diagnosis of the affected semicircular canal, the difference in cure rate was not significant （P=0.149）. The Kappa statistic indicated substantial agreement between RART and SRT in terms of eliciting nystagmus （agreement 96.36%, Kappa = 0.730, P<0.001）. Conclusion:RART and SRT show a high degree of agreement regarding the elicitation rate of nystagmus. RART is simple and safe, and it can effectively induce the characteristic nystagmus of HSC-BPPV, accurately identify the responsible semicircular canal and provide a more optimized examination protocol for clinical practice in HSCBPPV.

OBJECTIVE To evaluate the safety， efficacy， and cost-effectiveness of sodium-glucose co-transporter 2 （SGLT-2） inhibitors for treating type 2 diabetes mellitus （T2DM）. METHODS Retrieved databases such as PubMed， Cochrane Library， Embase， CNKI， as well as relevant health technology assessment （HTA） official websites， HTA reports， systematic review/meta- analysis and pharmacoeconomic studies about SGLT-2 inhibitors （including 12 types such as canagliflozin， dapagliflozin， and empagliflozin） in the treatment of T2DM were collected from the inception to January 28， 2025. After literature screening data extraction and quality assessment， a descriptive analysis was conducted on the results of the included studies. RESULTS A total of 38 articles were included， comprising 30 systematic reviews/meta-analyses， 4 pharmacoeconomic studies， and 4 HTA reports. In terms of effectiveness， most research results showed that canagliflozin was effective in controlling blood glucose， reducing body weight， and lowering blood pressure compared to other SGLT-2 inhibitors， while empagliflozin could effectively reduce all-cause mortality. In terms of safety， compared with other SGLT-2 inhibitors， empagliflozin has a lower overall adverse event rate and cardiovascular death risk， canagliflozin presented a higher risk of hypoglycemia， and dapagliflozin had a higher risk of urinary tract infections. In terms of economics， empagliflozin possessed greater economic advantages over both dapagliflozin and canagliflozin， while canagliflozin offered more benefits than dapagliflozin. CONCLUSIONS The selection of SGLT-2 inhibitors for the treatment of T2DM should be individualized. Canagliflozin is recommended for patients with high cardiovascular risk. Empagliflozin boasts the best overall safety profile. Dapagliflozin should be used with caution in patients at high risk of urinary tract infections. Based on foreign economic evidence， empagliflozin has economic advantages. In the future， drug economic studies under the Chinese health system need to be conducted.

OBJECTIVE To evaluate the safety， efficacy and economics of dapagliflozin in the treatment of type 2 diabetes mellitus （T2DM） combined with cardiovascular disease （CVD）， and provide an evidence-based basis for clinical treatment decisions. METHODS PubMed， the Cochrane Library， Embase， Web of Science， CNKI， Wanfang data， VIP， SinoMed and official websites of domestic and foreign health technology assessment （HTA） organizations were systematically searched. HTA reports， systematic evaluations/meta-analyses， and pharmacoeconomic studies of dapagliflozin in the treatment of T2DM combined with CVD were searched. After data extraction and quality assessment， the results of the included studies were analyzed descriptively. RESULTS A total of 13 papers were included， of which 10 were systematic evaluations/meta-analyses and 3 were pharmacoeconomic studies. In terms of efficacy， dapagliflozin significantly reduced patients’ glycosylated hemoglobin， body weight， body mass index and blood pressure levels compared with placebo， without increasing the risk of all-cause mortality； in terms of safety， dapagliflozin did not increase the risk of overall adverse events， major adverse cardiovascular events， cardiovascular death， hospitalization for heart failure， myocardial infarction， stroke， bone fracture and renal hypoplasia； in terms of economics， the UK and Chinese studies found an economic advantage for dapagliflozin， the Thai study did not. CONCLUSIONS Dagliflozin has better efficacy and safety in the treatment of T2DM combined with CVD， and its economic findings are still controversial in different countries， with economic advantages in the context of current Chinese healthcare policies and drug prices.

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 observe the effect of quercetin on mechanical allodynia,astrocyte activation,and upregulation of pain-related transient receptor potential vanilloid 1(TRPV1)and P2X purinoceptor 3(P2X3)in mice with paclitaxel-induced peripheral neuropathy.Methods Twenty-four C57BL/6 mice were divided randomly into control,model,and model+quercetin groups(n=8 mice per group).Paclitaxel(total dose 8 mg/kg)was injected intraperitoneally into mice in the model and model+quercetin groups to establish the model.Mice in the control group were injected intraperitoneally with the same volume of vehicle.On day 8 after the first injection,mice in the model+quercetin group were injected with 60 mg/kg quercetin solution orally and mice in the other groups were injected with the same volume of vehicle.Mechanical pain was measured by the von Frey test.Activation of astrocytes in the spinal dorsal horn was detected by immunofluorescence.Expression levels of TRPV1 and P2X3 in dorsal root ganglia were detected by immunofluorescence and Western Blot.Results(1)Compared with model group,the mechanical pain of mice in model+quercetin group were relieved.(2)Compared with model group,the activation of astrocytes and the expressions of TRPV1 and P2X3 in mice of model+quercetin group were alleviated(P＜0.05).Conclusions Quercetin can significantly reduce mechanical pain in mice with paclitaxel-induced peripheral neuropathy.This mechanism maybe related to alleviating the activation of astrocytes in the spinal dorsal horn and reducing expression of TRPV1 and P2X3 in the dorsal root ganglia.

Using the microbotox injection method, the botulinum toxin type A with a diluted concentration of 8 U/ml was micro-injected into the dermis layer or between the dermis and the superficial muscle layer at an interval of 0.6 cm, and a single point injection of 0.2 U. The injection range was the anatomical distribution range of the orbicularis oculi muscle. After treatment, patients were followed up to investigate patient satisfaction, which was divided into very satisfied, satisfied, dissatisfied and very dissatisfied, and to calculate subjective satisfaction (percentage of the number of very satisfied and satisfied cases in the total number of cases). At the same time, a independent physician used the global aesthetic improvement scale (GAIS) to evaluate the effect based on the patient’s photos before treatment and during follow-up. 5 indicates as worse than before, 4 as no improvement, 3 as were slight improvement, 2 as moderate improvement, and 1 as significant improvement. SPSS 24.0 software was used for descriptive analysis of the data.Results:A total of 23 patients were enrolled, including 1 male and 22 females, aged (36.4±2.5) years old. The follow-up was 1-6 months, with an average of 1.4 months, and the subjective satisfaction of patients was 100% (23/23). The result of the independent physician evaluation were as follows: the overall cosmetic improvement score of the observers was 1.26±0.54, 100% (23/23) of the patients reached the standard of obvious or moderate improvement. In terms of complications, 2 patients presented local epidermis bruises after injection, who recovered within 1 week; 1 patient complained of pain after injection, which was significantly relieved 12 hours later. No ectropion, symblepharon, facial palsy, dry eyes, or other complications were observed.Conclusion:Application of botulinum toxin type A microbotox injection can improve periorbital wrinkles and improve skin texture at the same time, and the therapeutic effect is definite.
