Clinical practice guidelines represent the best recommendations for patient care. They are developed through systematically reviewing currently available clinical evidence and weighing the relative benefits and risks of various interventions. However, clinical practice guidelines have to go through a long translation cycle from development and revision to clinical promotion and application, facing problems such as scattered distribution, high duplication rate, and low actual utilization. At present, the clinical practice guideline information platform can directly or indirectly solve the problems related to the lengthy revision cycles, decentralized dissemination and limited application of clinical practice guidelines. Therefore, this paper systematically examines different types of clinical practice guideline information platforms and investigates their corresponding challenges and emerging trends in platform design, data integration, and practical implementation, with the aim of clarifying the current status of this field and providing valuable reference for future research on clinical practice guideline information platforms.

This paper summarizes Professor AI Rudi's experience in the diagnosis and treatment of skin pruritus based on the "unity of restoring form， regulating qi， and harmonizing spirit"， employing internal herbal medicine combined with external treatments. It is believed that the core pathogenesis of pruritus is the "imbalance of form， qi， and spirit"， with disturbed spirit as the onset， disordered qi as the key pathogenic factor， and physical changes as the manifestation of the disease. The treatment principle follows "restoring form-regulating qi-harmonizing spirit"， with a combination of internal and external therapies， and differentiation based on deficiency and excess. For excess conditions caused by pathogenic disturbances to the heart spirit， treatment is based on different patterns of wind-heat， damp-heat， and blood-heat， using Sangye （Morus alba）-Sangbaipi （Morus alba cortex）-Longchi （Draconis os） to disperse wind and clear heat， calm the spirit； Difuzi （Kochia scoparia）-Qinghao （Artemisia annua）-Tanxiang （Santalum album） to clear damp-heat and aromatically open the spirit； Mudanpi （Paeonia suffruticosa）-Chuanxiong （Ligusticum chuanxiong）-Shuiniujiao （Bubalus bubalis cornua） to cool the blood， activate circulation， and calm the spirit. For deficiency conditions caused by insufficient nourishment of the heart spirit， treatment is based on patterns of qi deficiency or blood deficiency， using Huangqi （Astragalus membranaceus）-Fuping （Lemna minor）-Wuweizi （Schisandra chinensis） to tonify the qi and stabilize the exterior； Heshouwu （Polygonum multiflorum）-Jili （Tribulus terrestris）-Shouwuteng （Polygonum multiflorum vine） to nourish the blood， moisten dryness， and calm the spirit. External treatments integrate traditional Chinese medicine therapies such as medicinal baths， gua sha， and ear acupuncture， with custom herbal wash formulas for restoring form， jojoba oil gua sha for regulating qi， and ear seed therapy using Wangbuliuxing （Vaccaria segetalis） for harmonizing the spirit， achieving a holistic treatment effect for form， qi， and spirit.

Aim To explore the mechanism of Bushen Tongfu decoction(BSTF)improving the learning and memory ability of APP/PS1 mice.Methods The APP/PS1 mice were administered by BSTF for eight weeks.The spatial learning and memory ability of all mice were detected by Morris water maze.The changes in the intestinal microbiota and gut metabolites of mice were detected by 16S rDNA and LC-MS/MS technolo-gy.Results Compared with the model group,the es-cape latency and swimming path in BSTF-H,BSTF-M and BSTF-L groups were shortened and the times of target crossings after removing the platform increased significantly(P＜0.01).The 16S rDNA results showed that BSTF could increase the abundance of beneficial bacteria of Firmicutes and reduce the abun-dance of harmful bacteria of Bacteroidota in APP/PS1 mice.A total of 25 differential metabolites were identi-fied by LC-MS/MS,including sphingolipid metabo-lism,lysine metabolism and tyrosine metabolism.KEGG enrichment analysis showed that the therapeutic effect of BSTF was mainly through inflammation-related signaling pathways such as NF-κB pathways and Apelin pathways.Conclusions The mechanism of BSTF im-proving the learning and memory ability of APP/PS1 mice may be related to the improvement of intestinal flora composition,the effect of sphingolipid metabo-lism,lysine metabolism and tyrosine metabolism and the regulation of inflammation-related signaling path-ways such as NF-κB and Apelin pathways.

Aim To study the molecular mechanism of pterostilbene(PTS)inhibiting the growth of esophage-al squamous cell carcinoma(ESCC).Methods Soft agar assay was used to detect the effect of PTS on the anchored independent growth of KYSE150.TMT-la-beled quantitative proteomics analysis was used to ana-lyze the influence of PTS on the proteome of KYSE150.Then the differentially expressed proteins(DEPs)enrichment was analyzed by GO and KEGG,and signaling pathway interactions were analyzed by STRING database.The molecular docking model of PTS and PPARα was established by computer.Trans-mission electron microscopy was used to observe the in-fluence of PTS on the morphology change of KYSE150.Western blot analysis the effects of PTS on PPARα sig-naling pathway and ferroptosis related proteins expres-sion.Results PTS inhibited the anchorage-independ-ent growth capability of KYSE150.A total of 249 DEPs were identified by proteomic analysis,including 175 up-regulated proteins and 74 down-regulated pro-teins.The DEPs enrichment analysis showed that PPAR signaling pathway was related to unsaturated fat-ty acid synthesis,pyruvate metabolism and other meta-bolic signaling pathways.PTS caused the reduction of mitochondrial volume and mitochondrial cristae of KYSE150.PTS inhibited the expression of PPARα sig-naling pathway and ferroptosis related proteins.Con-clusion PTS induced the ferroptosis of ESCC by in-hibiting PPARα signaling pathway.

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 monitor the antifungal resistance of clinical isolates of Candida spp.in the East China region.Methods MALDI-TOF MS or molecular methods were used to re-identify the strains collected from January 2018 to December 2022.Antifungal susceptibility testing was performed using the broth microdilution method.The susceptibility test results were interpreted according to the breakpoints of 2022 Clinical and Laboratory Standards Institute(CLSI)documents M27 M44s-Ed3 and M57s-Ed4.Results A total of 3 026 strains of Candida were collected,65.33％of which were isolated from sterile body sites,mainly from blood(38.86％)and pleural effusion/ascites(10.21％).The predominant species of Candida were Candida albicans(44.51％),followed by Candida parapsilosis complex(19.46％),Candida tropicalis(13.98％),Candida glabrata(10.34％),and other Candida species(0.79％).Candida albicans showed overall high susceptibility rates to the 10 antifungal drugs tested(the lowest rate being 93.62％).Only 2.97％of the strains showed dose-dependent susceptibility(SDD)to fluconazole.Candida parapsilosis complex had a SDD rate of 2.61％and a resistance rate of 9.42％to fluconazole,and susceptibility rates above 90％to other drugs.Candida glabrata had a SDD rate of 92.01％and a resistance rate of 7.99％to fluconazole,resistance rates of 32.27％and 48.24％to posaconazole and voriconazole non-wild-type strains(NWT),respectively,and susceptibility rates above 90％to other drugs.Candida tropicalis had resistance rates of 29.55％and 26.24％to fluconazole and voriconazole,respectively,resistance rates of 76.60％and 21.99％to posaconazole and echinocandins non-wild-type strains(NWT),and a resistance rate of 2.36％to echinocandins.Conclusions The prevalence and species distribution of Candida spp.in the East China region are consistent with previous domestic and international reports.Candida glabrata exhibits certain degree of resistance to fluconazole,while Candida tropicalis demonstrates higher resistance to triazole drugs.Additionally,echinocandins resistance has emerged in Candida albicans,Candida glabrata,Candida tropicalis,and Candida parapsilosis.

Objective:To explore the application effects of whole-process nutritional management in patients undergoing thoracoabdominal laparoscopic radical esophagectomy.Methods:A total of 144 patients who underwent thoracoabdominal laparoscopic radical esophagectomy at the Jiangsu Cancer Hospital between February 2022 and February 2024 were selected using convenience sampling method. Patients were randomly assigned to a control group ( n=72) receiving routine care and an observation group ( n=72) receiving whole-process nutritional management in addition to routine care. Nutritional status, postoperative recovery, nursing satisfaction, and weight loss were compared between the two groups. Results:On the day before surgery, the Nutritional Risk Screening (NRS-2002) score of the observation group was significantly lower than that of the control group, the difference was statistically significant ( P<0.05). The observation group had earlier times to first ambulation, bowel movement, flatus, and fewer total complications compared to the control group, the differences were statistically significant ( P<0.05). Nursing satisfaction scores in the observation group were significantly higher than in the control group, the differences were statistically significant ( P<0.05). One month postoperatively, the observation group experienced less weight loss than the control group, the difference was statistically significant ( P<0.05) . Conclusions:Whole-process nutritional management improves preoperative nutritional status scores, reduces postoperative complications and weight loss, and enhances patient satisfaction with nursing care in esophageal cancer patients undergoing thoracoabdominal laparoscopic radical esophagectomy.

Hepatohilar cholangiocarcinoma is a common malignant tumor of the biliary system,and radical surgery is one of the important treatment methods.Due to the narrow space at the hi-lum and the high rate of anatomical variation,radical surgery is challenging.By using medical imag-ing technology and 3D reconstruction,surgeons can accurately determine the stage and classifica-tion of hilar cholangiocarcinoma preoperatively.They can assess the tumor's resectability by Ac-cording to the bile duct separation limit points(U point,P point)and anticipate the impact of portal vein,bile duct,and arterial variations on the surgical plan,thereby improving the rate of radical re-section and reducing complication rates.
