Objective To study the changes in interleukin-32 (IL-32) in rats with Klebsiella bacillus pneumonia and approach its significance. Methods Seventy-two Sprague-Dawley(SD)rats were divide into control group,model group and experimental group by the method of random digits table,then the experimental group was subdivided into 4 hours and 1,3 and 5 days experimental subgroups(each n=6). The rat model of Klebsiella bacillus pneumonia was established by injection of 0.3 mL Klebsiella bacterial suspension into the trachea. Before the establishment of the model in the experimental group,IL-32 inhibitory agent,protease activated receptor-2(PAR2) was injected into the abdominal cavity. After model establishment,at different time points,blood was collected via tail vein to observe the changes in serum levels of IL-32,tumor necrosis factor-α(TNF-α),IL-6 and IL-8 in all the groups. The lungs were removed and stained with hematoxylin-eosin(HE)method to investigate the histopathological changes of the lung tissues under the light microscope. Results Compared to the control group, with the prolongation of time the levels of IL-32,TNF-α,IL-8 and IL-6 were increased gradually in the model group,and reached their peaks at 3 days〔IL-32(ng/L):84.40±28.24 vs. 18.57±3.86,t=5.544,P=0.002;TNF-α(ng/L):79.27±14.64 vs. 17.82±3.86, t=9.994, P=0.000;IL-8(ng/L):55.85±10.90 vs. 16.66±3.76,t=8.544, P=0.000;IL-6(ng/L):56.65±2.57 vs. 28.48±2.11,t=19.693,P=0.000〕;PAR2 could inhibit above indexes significantly,there was statistical difference at 3 days compared with the model group〔IL-32(ng/L):54.13±6.68 vs. 84.40±28.24,t=2.560,P=0.046;TNF-α(ng/L):49.12±3.56 vs. 79.27±14.64,t=4.901,P=0.003;IL-8 (ng/L):22.95±2.52 vs. 55.85±10.90,t=7.204,P=0.000;IL-6(ng/L):36.49±2.63 vs. 56.65±2.57,t=13.443, P=0.000〕. Under the light microscope,the inflammatory changes in the lung tissue in experimental group were milder than those in the model group. Conclusion As a pro-inflammatory cytokine,IL-32 can induce the production of TNF-α,IL-6 and IL-8,and the inhibition of IL-32 production may play a role in suppression of the development of Klebsiella bacillus pneumonia.

Objective:To summarize the experience of blood glucose management and nursing for a newborn with repeated hypoglycemia in Beckwith-Wiedemann syndrome.Method:A multidisciplinary team was formed, and formulated an individualized care plan for a large infant with Beckwith-Wiedemann syndrome. A dynamic blood glucose monitoring system was used to closely monitor blood glucose fluctuations for this children, dynamically adjusted the amount of infusion and milk according to the blood sugar situation, detected and dealed with hypoglycemia in time, strengthened the skin care of child and implemented psychological care for the family.Results:After refined treatment and care, the child′s vital signs were stable, and his blood sugar could maintain within a normal range before being discharged from the hospital.Conclusions:The use of dynamic blood glucose monitoring system under the guidance of a multidisciplinary team can effectively monitor and control the blood glucose fluctuations of children with BWS syndrome, which can provide a basis for further treatment of children.

In this paper, we developed an accurate and sensitive LC-MS/MS method for the determination of amoxicillin and clavulanic acid in human plasma. A 50% aqueous acetic acid solution was used as a stabilizer, and the plasma samples were evaporated to dryness and resolved after protein precipitation on ice bathing and then were placed in an autosampler for injection. The gradient was eluted by Hedera ODS-2 column(2. 1 mm×150 mm). The aqueous phase was an aqueous solution containing 0. 2% acetic acid. The organic phase was methanol. The amoxicillin and clavulanic acid were detected under negative ion detection with electrospray ionization(ESI)in multiple reaction monitoring(MRM)mode of m/z 364. 1→223. 1 and 198. 1→135. 9 in the triple quagdrupole tandem mass spectrometer(Triple Quad TM 6500+). The concentration ranges of plasma from 20. 0 ng/mL to 5 000 ng/mL for amoxicillin and 10. 0 ng/mL to 2 500 ng/mL for clavulanic acid were good linear relationship. The accuracy deviation were ±15. 0% and precision were less than 15. 0% for the intra-assay and inter-assay. The matrix effect and recovery meeted the acceptance criteria, amoxicillin and clavulanic acid were stable under storage and processing conditions. Healthy subjects were given a test preparation of amoxicillin and clavulanate potassium granules 1 bag(125 mg/31. 25 mg/bag)and the reference preparation amoxicillin clavulanate potassium dry mix Suspension “Augmentin® ” 5 mL(125 mg/31. 25 mg/5 mL)was used to determine the plasma concentration of amoxicillin and clavulanic acid. The Phoenix WinNonlin 6. 4 software was used to estimate the pharmacokinetic parameters of non-compartmental models. The pharmacokinetic parameters of amoxicillin and clavulanic acid were statistically calculated and evaluated the bioequivalence. what′s more, we evaluated the diet on the pharmacokinetics of amoxicillin and clavulanic acid. The analytical method was rapid and sensitive, which was successfully employed in the bioequivalence study of amoxicillin(125 mg/bag)and clavulanate potassium granules(31. 25 mg/bag)for determining the concentration of amoxicillin and clavulanic acid.

The clinical practice guidelines for prevention and treatment of postoperative gastrointestinal disorder with Integrated Traditional Chinese and Western Medicine (2023) issued by the Anaesthesia Committee and Perioperative Medicine Committee of the Chinese Society of Integrative Medicine is the first evidence-based guideline for postoperative gastrointestinal disorder in China. It covers the definition, aetiology and pathogenesis, diagnosis and treatment of postoperative gastrointestinal disorder. Compared with previous expert consensus, this guideline has advantages in terms of scientific and rigorous methodology and is quite representative. Interpreting this guideline can help strengthen clinicians′ understanding of postoperative gastrointestinal disorder and enhance clinical practitioners′ understanding of the methodology of this guideline, thus enabling a better integration of recommendations and evidence for clinical practice and hastening the implementation of the guidelines. It also accelerates the dissemination of the methodological development of guidelines in China, helps clinicians understand the connotation and value of the guidelines, and provides methodological guidance and references for formulating clinical practice guidelines based on the current situation in China and involving other clinical disciplines.

Objective To evaluate the efficacy of preoperative electroacupuncture intervention in promoting postoperative gastrointestinal functional recovery by meta-analysis.Methods The databases of PubMed,Cochrane Library,Web of Science,Embase,CBM,CNKI,VIP,and WanFang were searched systematically.The search period ranged from the inception of the databases to March 2024.Two researchers screened the literature independently,extracted the data,used Cochrane Risk of Bias tools to evaluate the quality of the inclusion study,and used RevMan 5.3 software for meta-analysis.Results Twelve RCTs were included,with 773 patients.There were 421 patients in the preoperative electroacupuncture group and 352 patients in the control group.The results of the meta-analysis showed that,time to first flatus(SMD=-0.56,95%CI-0.84 to-0.28,P<0.001),time to first defecation(MD=-6.40 hours,95%CI-9.27 to-3.53,P<0.001),time to bowel sound recovery(MD=-8.45 hours,95%CI-10.37 to-6.52,P<0.001),time to first oral feeding(MD=-16.88 hours,95%CI-23.92 to-9.83,P<0.001),the incidence of PONV(RR=0.75,95%CI 0.57 to 0.98,P=0.04)and length of hospital stay(MD=-0.78 d,95%CI-1.38 to-0.19,P=0.010)were significantly lower than the control group.Conclusion Electroacupuncture intervention before operation can effectively promote the recovery of post-operative exhaust,defecation,and bowel sound,shorten the time of fasting and drinking,reduce the inci-dence of PONV,shorten the length of hospital stay,and has good clinical value in promoting the recovery of postoperative gastrointestinal function.
