This article adopts Professor CHEN Chaozu′s " sanjiao composed by membrane-striae" theory as its foundation to explore the relationship between irritable bowel syndrome and functional/structural abnormalities of the membrane-striae. Sanjiao encompasses both the tangible membrane and the intangible striae. These striae permeate the entire body，and their pathological changes comprehensively reflect qi，body fluids，and fasciae. Based on the physiological function of the membrane-striae in regulating qi and fluids，the pathogenesis of irritable bowel syndrome is characterized by a disharmony of membrane-striae and an imbalance of the qi-fluid interactions. In the early stage，external pathogens，emotional factors，or dietary stimuli often cause membrane-striae constriction and disordered qi-fluid circulation. In the middle stage，stagnant fluids gradually transform into phlegm retention，leading to membrane-striae obstruction. In the late stage，deficiency of vital qi becomes predominant，manifesting as laxity of membrane-striae with impaired control or weakened conduction. The treatment of irritable bowel syndrome should adopt " unblocking" as the guiding principle. In the early stage，therapy should focus on eliminating pathogenic factors and soothing membrane-striae to promptly restore qi-fluid circulation，thereby attaining unblocking through spasm relief. In the middle stage，treatment should focus on resolving tangible obstructions in membrane-striae，achieving unblocking via dredging. In the late stage，the emphasis should shift to reinforcing healthy qi，particularly by strengthening spleen-kidney yang qi，and achieving unblocking through supplementation. Concurrently，throughout the entire treatment process，the regulation of mental state and easing of emotional tension should be integrated to alleviate patient′s anxiety，achieving the goal of holistic treatment of both body and mind.

OBJECTIVE To explore the effect of the comprehensive unit-based safety program(CUSP)collaborative action strategy on reducing the incidence of catheter-associated urinary tract infection(CAUTI)in elderly patients.METHODS From Jun.to Nov.2024,the Seventh Medical Center of the PLA General Hospital implemented the CUSP collaborative action strategy for intervention.Comparisons were made between pre-intervention(from Dec.2023 to May 2024)and post-intervention(from Jun.to Nov.2024)regarding nurses' know ledge-attitude-practice(KAP)scores on CAUTI prevention,implementation rates of key nursing measures for elderly CAUTI prevention and CAUTI incidence rates among elderly patients.RESULTS The pre-intervention KAP score of nurses from geriatric de-partment on CAUTI prevention was(83.44±6.67),significantly lower than the post-intervention score(108.19±16.27)(P＜0.001).The implementation rates of 10 key nursing measures for elderly CAUTI prevention improved(P＜0.05).The incidence rate of CAUTI was 2.88‰(16/5 546)among 5 546 catheter days before the intervention,and the incidence rate of CAUTI was 0.73‰(4/5 496)among 5 496 catheter days after the intervention(P=0.008).CONCLUSIONS The CUSP collaborative action strategy effectively enhances the KAP levels of nurses from geriatric department on CAUTI prevention,improves the implementation rates of key nursing measures,and reduces CAUTI incidence rates among elderly patients.

Objective To understand the epidemiological characteristics and trends of postoperative pneumonia(POP)in tertiary general hospitals in Jiangsu Province,and provide theoretical basis for carrying out targeted pre-vention and control measures.Methods Surgery patients from 22 tertiary general hospitals in 12 cities in north,central,and south of Jiangsu Province from January 1,2022 to December 31,2023 were chosen as studied subjects,occurrence of POP was analyzed and compared.Results A total of 848 274 surgical procedures were performed in 22 hospitals,and 3 606 cases of POP occurred,with an incidence of 0.43％.The incidence in 2023 was 0.37％,which was lower than that in 2022(0.49％),with statistically significant difference(P＜0.001).The top three de-partments with high incidence of POP were neurosurgery(6.71％),cardiothoracic surgery(2.91％),and general surgery(0.77％).Among hospitals of different grades,the incidence of POP in tertiary first-class hospitals was 0.44％,which was higher than that in other tertiary hospitals(0.37％).There was no statistically significant difference in the incidence of POP between municipal and district/county hospitals(P＞0.05).The incidence of POP in hospitals with a bed:infection control full-time staff ratio＜200∶1 was lower than that in hospitals with the ratio ≥200∶1(0.39％vs 0.47％,P＜0.001),while the incidence of POP in hospitals with a proportion ≥30％of full-time staff being doctors was higher than that in hospitals with a proportion＜30％(0.45％vs 0.36％,P＜0.001).The incidence of POP in male patients was higher than that in female patients(0.62％vs 0.26％,P＜0.001).The incidence of POP in elderly patients aged≥65 was higher than that in patients aged＜65(0.73％vs 0.26％,P＜0.001).A total of 2 667 strains of infectious pathogens were detected,with the top three being Acine-tobacter baumannii,Klebsiella pneumoniae,and Pseudomonas aeruginosa,accounting for 28.95％,22.72％,and 15.45％,respectively.The detection rates of carbapenem-resistant Acinetobacter baumannii(CRAB),carba-penem-resistant Klebsiella pneumoniae(CRKP),and carbapenem-resistant Pseudomonas aeruginosa(CRPA)were 60.75％,21.45％,and 32.28％,respectively.The detection rate of CRKP decreased in 2023 compared with 2022,with statistically significant difference(P＜0.05).Conclusion The overall incidence of POP in tertiary general hos-pitals in Jiangsu Province is relatively low,but there are significant differences among different hospitals.There-fore,perioperative prevention and control measures should be carried out based on the epidemiological characteristics of patients.

Objective To investigate the application effect of a refined early diet plan in patients with distal gastric cancer after laparoscopic radical surgery.Methods By convenience sampling method,46 patients with laparoscopic radical gastrectomy for distal gastric cancer admitted to a tertiary hospital in Zhejiang Province from July to December 2023 were selected as an experimental group,while 49 patients admitted from January to June 2023 as a control group.The experimental group was administered with the refined early diet plan,and the control group was administered with conventional methods.The intervention period was from the first day after surgery to discharge.The differences of the first postoperative defecation time,perioperative thirst and hunger score,postoperative hospitalization time,hospitalization cost,postoperative complications and the incidence of readmission 30 days after surgery were compared between the 2 groups.Results 42 patients in the experimental group and 49 patients in the control group completed the study.First postoperative exhaust time(t=4.922,P＜0.001),first postopera-tive defecation time(Z=-2.440,P=0.015),perioperative thirst score(Z=-8.024,P＜0.001),perioperative hunger score(Z=-8.192,P＜0.00 1),postoperative hospitalization time(Z=-7.622,P＜0.001)and hospitalization cost(Z=-4.522,P＜0.001)were lower than those of the control group,and the difference was statistically significant.There was no significant difference in complication rate and 30-day readmission rate between the experimental group and the control group(P＞0.05).Conclusion The refined early diet plan is safe and effective for early recovery of patients after laparoscopic radical gastrectomy for distal gastric cancer,promoting intestinal function recovery,shortening hospital stay,reducing hospital costs,and improving patients'subjective comfort.

Objective To compare the efficacy and safety of sodium zirconium cyclosilicate and calcium polystyrene sulphonate in the treatment of hyperkalemia in chronic kidney disease(CKD).Methods Hospitalized patients with CKD hyperkalemia admitted to Qingyuan People's Hospital from January 2022 to November 2023 were retrospectively selected as study objects,and were divided into sodium zirconium cyclosilicate group and calcium polystyrene sulphonate group according to different drug use.The two groups of patients were matched with 1:1 propensity score,and finally 43 pairs of data were successfully matched.The efficacy and incidence of adverse reactions were compared between two groups of patients after matching.Results After treatment,the serum potassium level in both groups was significantly lower than that before treatment(P<0.05),but there was no significant difference in serum potassium level between two groups(P>0.05).There was no significant difference in the total effective rate between two groups(χ2=1.242,P=0.537).After treatment,the blood sodium level in sodium zirconium cyclosilicate group was significantly higher than that before treatment(P<0.05),there was no significant difference in blood calcium level before and after treatment(P>0.05).There was no significant difference in serum sodium and serum calcium before and after treatment in calcium polystyrene sulphonate group(P>0.05).There was one patient with hypokalemia in each group,and no treatment related adverse reactions such as nausea,edema,constipation,abdominal bloating and diarrhea were observed,and no abnormal laboratory test results were found.Conclusion The clinical efficacy of sodium zirconium cyclosilicate and calcium polystyrene sulphonate in treatment of hyperkalemia in CKD patients is comparable,and the safety is good.

Objective:Migraine and tremor share some genetic mutation sites,and clinical studies have also confirmed their correlation.This study aims to explore the clinical and electrophysiological characteristics of migraine patients with concomitant tremor,and to analyze the relevant influential factors of tremor occurrence. Methods:We retrospectively analyzed the clinical data of 217 migraine patients who visited the Third Affiliated Hospital of Qiqihar Medical University from June 2022 to October 2023.The Clinical Rating Scale for Tremor(CRST),Numerical Rating Scale(NRS),Generalized Anxiety Disorder-7(GAD-7),and Patient Health Questionnaire-9(PHQ-9)were respectively used to assess the tremor symptoms,degree of headache,anxiety,and depression of patients.All patients underwent routine head MR scanning and electromyography examination,and were divided into a migraine with tremor group and a migraine without tremor group based on the electromyogram examination. Results:The migraine with tremor group and the migraine without tremor group were included 52 patients(23.96%)and 165 patients(76.04%),respectively.Compared with the migraine without tremor group,the migraine with tremor group had a longer course and duration of headache,higher frequency of headache attacks,higher NRS score,GAD-7 score,and PHQ-9 score,and fewer weekly physical exercises.The differences were statistically significant(all P<0.05).There were no statistically significant differences in the presence or absence of prodromal headache and white matter hyperintensities(WMHs)between the 2 groups(both P>0.05).The evaluation results of the CRST showed that out of 217 migraine patients,39 patients(17.97%)were accompanied by tremors.The electromyographic results showed that all 52 migraine patients with tremors had upper limb tremors,including 28 migraine patients with postural tremors and 24 migraine patients with static tremors.Compared with the migraine patients with static tremors,the migraine patients with postural tremors had lower average frequency,peak frequency,and headache onset frequency(all P<0.05).Multiple linear regression analysis showed that frequency of physical exercise,duration of illness,frequency of headache attacks,NRS score,GAD-7 score,and PHQ-9 score were risk factors for migraine patients with concomitant tremors(all P<0.05). Conclusion:Patients with migraine mainly experience upper limb postural tremors.Reduced physical exercise,long course of disease,long duration of headache,frequent headache attacks,severe headache,anxiety,and depression are risk factors for migraine patients with concomitant tremors.
