Objective To investigate the distribution of homeostasis model assessment-insulin resistance(HOMA-IR)index and its relationship with metabolic syndrome and inflammatory cytokines in students aged 7 to 14 years. Methods The data of 366 students(n=163 for boys and n=203 for girls) aged 7 to 14 years were collected,including anthropometric parameters (height,body weight,body mass index,waist circumference,hip circumference and waist-hip ratio),blood pressure,total fat mass,fat proportion,fasting blood lipid,fasting blood glucose,fasting insulin and serum levels of inflammatory cytokines such as tumor necrosis factor-α(TNF-α),C-reactive protein(CRP)and interleukin-6(IL-6),and insulin resistance was evaluated by HOMA-IR index. Results The 75 th percentile of HOMA-IR index for boys and girls was 3.62 and 2.88,respectively.Body weight,height,body mass index,waist circumference,hip circumference,total fat mass and fat proportion were positively related to HOMA-IR index(P<0.01).When HOMA-IR index surpassed 75th percentile,age,anthropometric parameters,total fat mass,fat proportion and systolic blood pressure significantly increased in boy and girl students(P<0.05),no significant change occurred in diastolic blood pressure in boy and girl students,the levels of serum TNF-α and IL-6 significantly increased in boy students(P<0.05),while there was no significant change in level of CRP in boy students and levels of CRP.TNF-α and IL-6 in girl students. Conclusion The increase of HOMA-IR index leads to a dramatic increase of anthropometrie parameters,total fat mass,fat proportion and serum TNF-α and IL-6 in boy students,while that results in the increase of anthropometric parameters,total fat mass and fat proportion in sid students,with no significant change in serum inflammatory cytokines.

A comprehensive analytical method based on UPLC-MS/MS was developed for the simultaneous determination of thirteen components including three stilbenes (stilbeneglucoside, polydatin, resveratrol), four anthraquinones (emodin, physcion, emodin-8-β-D-glucopyranoside, aloe-emodin), five flavonoids (epicatechin, rutin, hyperoside, astragalin,quercetin) and one phenolic acid (gallic acid) in Polygoni Multifori Caulis.The separation was carried out on a Waters BEH C18 column(2.1 mm×100 mm,1.7 μm)with gradient elution of acetonitrile-water (0.1% acetic acid) at a flow rate of 0.25 mL•min⁻¹, and column temperature was 35 ℃. The target compounds were analyzed by multiple reaction monitoring (MRM) mode. TOPSIS analysis ware performed to evaluate the samples from different areas and commercial herbs according to the contents of thirteen components. The correlation coefficients of all the calibration curves were higher than 0.991 5. The average recoveries ranged from 95.24% to 102.3%, and the relative standard deviations were less than 5%. The result of TOPSIS analysis showed that the comprehensive quality of Polygoni Multifori Caulis sample from Guangzhou was better. The developed method with good repeatability and accuracy was suitable for the simultaneous determination of multiple functional substances, which provided a new basis for the comprehensive assessment and overall control of the quality of Polygoni Multifori Caulis.

Objective:To evaluate the effect of ultrasound-guided subserratus anterior plane block on postoperative analgesia in patients un-dergoing laparoscopic radical gastrectomy.Methods:Sixty patients who underwent elective laparoscopic radical gastrectomy were enrolled between May 2022 and October 2023 at Tianjin Medical University Cancer Institute&Hospital.Patients were assigned into two groups us-ing a random number table method:the control(group C)and the ultrasound-guided serratus anterior plane block(SAPB)(group S).Patient-controlled intravenous analgesia(PCIA)was administered at the end of the surgery.After surgery,visual analogue scale(VAS)of static pain scores was evaluated at 1,6,12,24,and 48 hours.PCIA pump was started at the VAS pain score≥4 after surgery,and sufentanil 0.1μg/kg was intravenously injected when the efficacy was inadequate.The requirement for PCIA use,time to first postoperative anal exhaust,first postoperative out-of-bed activity,first oral intake,and the duration of hospitalization stay were recorded for the two groups.Results:VAS scores were significantly lower at postoperative 1,6,and 12 h in group S than in group C(P<0.05).Additionally,the number of effective uses of PCIA,and rescue analgesia were significantly lower in group S[(6.1±0.4)(2)]than in group C[(18.6±1.4)(17)](P<0.001).The time to first postoperative anal exhaust,first postoperative out-of-bed activity,first oral intake,and duration of hospital stay were shortened in group S than in group C(P<0.05).There were no significant differences in other parameters between these two groups.Conclusion:Ultrasound-guided SAPB can reduce postoperative pain and facilitate fast recovery in laparoscopic radical gastrectomy patients.
