As a new hypoglycemic drug,Dapagliflozin has attracted much attention because of its unique hypoglycemic mechanism. It has been used in many studies on type 2 diabetes mellitus,but the application of type 1 diabetes mellitus(T1DM)in the eastern population is rare. This article uses Dapagliflozin through a case of obese T1DM to provide new ideas for the treatment of T1DM.

Intestinal dysbiosis and disrupted bile acid(BA)homeostasis are associated with obesity,but the precise mechanisms remain insufficiently explored.Hepatic protein phosphatase 1 regulatory subunit 3G(PPP1R3G)plays a pivotal role in regulating glycolipid metabolism;nevertheless,its obesity-combatting potency remains unclear.In this study,a substantial reduction was observed in serum PPP1R3G levels in high-body mass index(BMI)and high-fat diet(HFD)-exposed mice,establishing a positive correlation between PPP1R3G and non-12α-hydroxylated(non-12-OH)BA content.Additionally,hepatocyte-specific overexpression of Ppp1r3g(PPP1R3G HOE)mitigated HFD-induced obesity as evidenced by reduced weight,fat mass,and an improved serum lipid profile;hepatic steatosis alleviation was confirmed by normalized liver enzymes and histology.PPP1R3G HOE considerably impacted systemic BA homeostasis,which notably increased the non-12-OH BAs ratio,particularly lithocholic acid(LCA).16S ribosomal DNA(16S rDNA)sequencing assay indicated that PPP1R3G HOE reversed HFD-induced gut dysbiosis by reducing the Firmicutes/Bacteroidetes ratio and Lactobacillus population,and elevating the relative abundance of Blautia,which exhibited a positive correlation with serum LCA levels.A fecal microbiome transplantation test confirmed that the anti-obesity effect of hepatic PPP1R3G was gut microbiota-dependent.Mechanistically,PPP1R3G HOE markedly suppressed hepatic cholesterol 7α-hydroxylase(CYP7A1)and sterol-12α-hydroxylase(CYP8B1),and concurrently upregulated oxysterol 7-α hydroxylase and Takeda G protein-coupled BA receptor 5(TGR5)expression under HFD conditions.Furthermore,LCA administration significantly mitigated the HFD-induced obesity phenotype and elevated non-12-OH BA levels.These findings emphasize the significance of hepatic PPP1R3G in ameliorating diet-induced adiposity and hepatic steatosis through the gut microbiota-BA axis,which may serve as potential ther-apeutic targets for obesity-related disorders.

Objective:To compare the effects of unilateral thoracic paravertebal block with lidocaine on hemodynamic and the level of consciousness during double lumen endotracheal intubation.Methods:From June to october 2021,a total of 40 patients American Society of Anesthesiologists(ASA)physical status Ⅰ-Ⅱ,aged 19-65 years,scheduled for elective thoracic sugeries in Peking University Interna-tional Hospital block with under general anesthesia requiring orotracheal intubation were recruited and di-vided into two groups:The double-lumen endobronchial intubation(group C)and double-lumen endo-bronchial intubation after thoracic paravertebal block with lidocaine(group P).After an intravenous an-esthetic induction,the orotracheal double-lumen intubation was performed using a Macintosh direct laryn-goscopy,respectively.Invasive blood pressure(BP)and heart rate(HR)were recorded before and after anesthetic induction,immediately after intubation and 5 min after intubation with 1-minute interval and the intubation time was also noted.Rate-pressure product(RPP)were calculated.Results:After anes-thetic induction,BP and RPP in the two groups decreased significantly compared with their preinduction values.As comparison with their postinduction values,the orotracheal intubation in the two groups caused significant increases in BP,HR and RPP.Diastolic blood pressure(DBP)and mean arterial pressure(MAP)increased significantly and lasted for 1-minute in group C compared with the baseline values.Systolic blood pressure(SBP)was not significant change and DBP increased significantly immediately af-ter intubation in group P.HR of both groups after intubation were significantly higher than their baseline values and lasted for 4 min in group C,HR increased significantly immediately after intubation in group P.SBP,DBP,MAP,HR and RPP after intubation in group P were significantly lower than those of group C during the observation period.The value of BIS was similar between the two groups.Compared with group C,the incidence of SBP greater than 30％and RPP greater than 22 000 was significantly lower in group P in the observation period,and no patient in group P developed RPP greater than 22 000.At the end of the incidence of SBP less than 30％of the basal value and HR less than 30％of the baseline,no severe bradycardia occurred in both groups.Conclusion:During double-lumen endobronchial intubation,unilateral thoracic paravertebal block with lidocaine can provide less hemodynamic response and level of conscionsness.

Objective:This study aims to investigate the relationship between high-risk human papillomavirus (HR-HPV) infection and the composition of vaginal microecology. It will analyze the efficacy of integrated traditional Chinese and Western medicine intervention in treating HR-HPV infection, as well as the effects of this combined approach on vaginal microecology. Additionally, the study seeks to identify new methods to inhibit the malignant progression of cervical intraepithelial lesions.Methods:A prospective study was conducted involving 100 patients with HR-HPV infection who visited the Department of Gynecology, The Second Affiliated Hospital of Shaanxi University of Chinese Medicine from April to June 2023. The participants were randomly divided into a control group and an observation group, with 50 patients in each group using a random number table method. The control group received interferon treatment, while the observation group was treated with a combination of interferon and Yanfukang Lotion. High-throughput DNA sequencing of vaginal secretions was conducted to compare the differences in pre- and post-treatment vaginal microecological composition and the rate of HR-HPV clearance between the two groups. Results:In the observation group, both the diversity index and the abundance of vaginal microecology showed significant improvements compared with the control group, particularly in the abundance of dominant Lactobacillus species. These differences were statistically significant ( R = 0.124, 0.304, 0.030, all P < 0.05). The rates of HR-HPV clearance and overall effective rate (clearance + effective) in the observation group were 44% (22/50) and 68% (34/50), respectively, which were significantly higher than those in the control group [20% (10/50), 32% (16/50), χ2 = 12.98, both P < 0.05). There was no statistically significant difference in the incidence of adverse reactions between the two groups (χ2 = 1.76, P > 0.05). Conclusion:The combination of interferon and Yanfukang Lotion effectively treats HR-HPV infection by regulating the composition of vaginal microecology. This approach shows considerable efficacy and good safety, indicating its potential for further clinical application.

Abstract: Objective　In order to explore the application prospects of the phenyl pyrazole insecticide fipronil for mosquito control and identify potential target genes involved in the resistance of Aedes aegypti to fipronil, and lay the foundation for an in-depth study of the resistance mechanism of Aedes aegypti to fipronil. Methods　Using Aedes aegypti sensitive strains as experimental materials, Aedes aegypti larvae were treated with fipronil, and the differences in gene expression of Aedes aegypti larvae before and after drug administration were compared at the transcriptome level using transcriptome sequencing combined with bioinformatics analysis, and the differential genes were analyzed. Results　A total of 757 differentially expressed genes were identified between the fipronil-treated group and control group, including 217 and 540 up- and down-regulated genes, respectively. Among these, the expression of glutamate-gated chloride channel (GluCls) genes varied significantly before and after treatment. Gene ontology analysis revealed that differentially expressed genes were enriched in catalytic activity, binding, metabolic processes, and membrane-related functions, while KEGG pathway analysis indicated enrichment in biosynthesis, metabolism, and life regulation processes, while the glutathione metabolic pathway was enriched in 15 differentially expressed genes. Conclusions The transcriptome results revealed that GST gene expression was significantly upregulated in fipronil-treated Aedes aegypti larvae, indicating that GST gene is involved in the development of fipronil resistance in Aedes aegypti larvae. In addition, GluCls gene expression was also significantly different before and after treatment, suggesting that GluCls migh be a potential target receptor for fipronil resistance in Aedes aegypti. As GluCls is an ideal target receptor found only in invertebrates, this discovery provides a reference and basis for further exploration of the toxicological mechanism of fipronil on Aedes aegypti.

BACKGROUND: Given the general unavailability, common adverse effects, and complicated administration of tetracycline, the clinical application of classic bismuth quadruple therapy (BQT) is greatly limited. Whether minocycline can replace tetracycline for Helicobacter pylori ( H . pylori ) eradication is unknown. We aimed to compare the eradication rate, safety, and compliance between minocycline- and tetracycline-containing BQT as first-line regimens. METHODS: This randomized controlled trial was conducted on 434 naïve patients with H . pylori infection. The participants were randomly assigned to 14-day minocycline-containing BQT group (bismuth potassium citrate 110 mg q.i.d., esomeprazole 20 mg b.i.d., metronidazole 400 mg q.i.d., and minocycline 100 mg b.i.d.) and tetracycline-containing BQT group (bismuth potassium citrate/esomeprazole/metronidazole with doses same as above and tetracycline 500 mg q.i.d.). Safety and compliance were assessed within 3 days after eradication. Urea breath test was performed at 4-8 weeks after eradication to evaluate outcome. We used a noninferiority test to compare the eradication rates of the two groups. The intergroup differences were evaluated using Pearson chi-squared or Fisher's exact test for categorical variables and Student's t -test for continuous variables. RESULTS: As for the eradication rates of minocycline- and tetracycline-containing BQT, the results of both intention-to-treat (ITT) and per-protocol (PP) analyses showed that the difference rate of lower limit of 95% confidence interval (CI) was >-10.0% (ITT analysis: 181/217 [83.4%] vs . 180/217 [82.9%], with a rate difference of 0.5% [-6.9% to 7.9%]; PP analysis: 177/193 [91.7%] vs . 176/191 [92.1%], with a rate difference of -0.4% [-5.6% to 6.4%]). Except for dizziness more common (35/215 [16.3%] vs . 13/214 [6.1%], P = 0.001) in minocycline-containing therapy groups, the incidences of adverse events (75/215 [34.9%] vs . 88/214 [41.1%]) and compliance (195/215 [90.7%] vs . 192/214 [89.7%]) were similar between the two groups. CONCLUSION: The eradication efficacy of minocycline-containing BQT was noninferior to tetracycline-containing BQT as first-line regimen for H . pylori eradication with similar safety and compliance.

Objective:To investigate the perioperative alterations and management of coagulation function in patients of massive blood transfusion during retroperitoneal tumor (RT)resection.Methods:Fourty-seven RT patients at Peking University International Hospital from Jan 2016 to Dec 2021 undergoing resection with massive blood transfusion more than 20 U within 24 h were reviewed for coagulation function before and after surgery.Results:Intraoperative bleeding was 3 000-25 800 ml, 10 patients had blood loss ≥10 000 ml. During the operation, (25.3±9.9) U of red blood cells were transfused, (2 720±1 369) ml plasma transfused, and (2.4±3.3) U platelets were transfused in 6 patients. Fourty-five patients received intraoperative albumin of (79.5±46.5) g; All 47 patients received fibrinogen of (2.3±1.3) g; Prothrombin complex was given in 45 patients (1 205±807) U. Preoperative hemoglobin was statistically different compared to postoperatively and days 1, 3 and 5 ( W=1 790, P<0.001; W=1 672, P<0.001; W=1 704, P<0.001; W=1 486, P=0.004);As with platelets, the difference was also statistically significant compared to postoperative days 1, 3, and 5 ( W=2 153, P<0.001; W=2 092, P<0.001; W=1 732, P<0.001); Preoperative albumin was different compared to postoperative days 1 and 3 ( W=1 568, P<0.001; W=1 578, P<0.001,); Preoperative fibrinogen was different compared to postoperative day 1 ( W=1 964, P<0.001). PT and APTT were prolonged on postoperative days 1 and 3 ( W=628, P<0.001, W=804, P=0.023) ( W=661, P<0.001, W=796, P=0.02). Patient's preoperative fibrin degradation products and D-dimer were above the normal value and were higher on postoperative days 3 and 5 ( W=498, P<0.001, W=345, P<0.001). Conclusions:Coagulation disorders occur perioperatively in patients with massive transfusion while undergoing surgery for RT.The implementation of ratiional transfusion strategy and close postoperative survey and management of coagulation dysfunction help avoid the coagulation related morbidities.
