Severe acute pancreatitis （SAP） is closely related to dysfunction of the spleen-stomach ascent and descent. Due to the influence of modern lifestyle and dietary factors， Qi deficiency in the spleen and stomach has become the pathological basis of SAP. Its pathogenesis is characterized by dampness， heat， pathogenic factors， stasis， stagnation， obstruction， Fu-organs Qi obstruction， pathogenic excess， and healthy Qi deficiency. At different stages of the disease course of SAP， there is a focus on both pathogenic excess and healthy Qi deficiency. It is specifically manifested as Fu-organs stagnation and heat accumulation， as well as pathogenic excess and healthy Qi deficiency， during the systemic inflammatory response phase， intermingling of blood stasis and pathogenic factors， as well as Qi deficiency and blood stasis， during the infection period， and weakness of the spleen and stomach， as well as healthy Qi deficiency and lingering pathogenic factors， during the residual infection period. Based on the theory that "the spleen and stomach are the acquired foundation"， a staged treatment method centered on the core principle of "strengthening healthy Qi to eliminate pathogenic factors" was developed. The staged treatment method included "clearing the Fu-organs to expel turbidity， replenishing Qi to harmonize the stomach， activating blood circulation to expel pathogenic factors， replenishing Qi to relieve pain， promoting digestion to stimulate appetite， and replenishing Qi to invigorate the spleen". In clinical practice， Hewei Tongxie mixture， Yikang mixture， and Shiwei Jianpi Xiaoshi powder were selected for staged treatment of SAP. This article systematically summarized the theoretical basis of traditional Chinese medicine， Western medicine foundation， modern pharmacological mechanisms， and clinical application experience of the staged treatment of SAP with "strengthening the healthy Qi to eliminate pathogenic factors"， providing new ideas for the treatment of SAP with traditional Chinese medicine.

ObjectiveTo evaluate the therapeutic effect of Shenji Guben prescription （SJGB） on chronic obstructive pulmonary disease （COPD） in mice and to explore its potential therapeutic mechanism via transcriptomics. MethodsA mouse model of COPD was established by combined exposure to lipopolysaccharide （LPS） and cigarette smoke. C57BL/6J mice were randomly allocated into a control group， a model group， an acetylcysteine （78 mg·kg^-1·d^-1） group， and low- （7.5 g·kg^-1·d^-1）， medium- （15 g·kg^-1·d^-1）， and high-dose （30 g·kg^-1·d^-1） SJGB groups. After 13 weeks of modeling， oral administration was initiated and continued for 28 days. The therapeutic effects of SJGB were assessed based on body weight， lung function， lung tissue pathology， and inflammatory factors in bronchoalveolar lavage fluid （BALF）. Ultra-high performance liquid chromatography-tandem mass spectrometry （UHPLC-MS/MS） was employed to identify the active ingredients in SJGB. Transcriptomic profiling of lung tissue was performed by RNA-seq to identify differentially expressed genes （DEGs）， followed by gene ontology （GO） enrichment analysis， Kyotoencyclopedia of Genes and Genomes （KEGG） enrichment analysis， Gene Set Enrichment Analysis （GSEA）， and protein-protein interaction （PPI） network construction. Key genes were further validated by Western blot and Real‑time polymerase chain reaction （Real-time PCR）. ResultsAfter drug intervention， the final body weights of mice in medium- and high-dose SJGB groups were higher than those in the model group （P<0.05）. Compared with the model group， SJGB groups demonstrated a significant decrease in expiratory time （Te）， along with increases in peak expiratory flow （PEF）， 50% expiratory flow （EF50）， tidal volume （TV）， and expiratory volume （EV） （P<0.05）. High-dose SJGB ameliorated pathological changes in the lung tissue， reduced peribronchial inflammation scores， and decreased mean linear intercept （MLI） （P<0.01）. Compared with the model group， medium- and high-dose SJGB groups showed reductions in interleukin-6 （IL-6） and interleukin-1β （IL-1β） levels （P<0.01）. UHPLC-MS/MS revealed that the five most abundant components in SJGB were （S）-actinidine， ephedrine， pyroglutamic acid， methylephedrine， and coumarin. Transcriptomic analysis revealed 219 DEGs regulated by SJGB， suggesting that the anti-COPD effects of SJGB may be mediated through key genes such as cluster of differentiation 68 （CD68）， integrin subunit alpha X （ITGAX）， and cathepsin S （CTSS）， primarily involved in the lysosomal pathway. Western blot and Real-time PCR results confirmed that SJGB inhibited the expression of CD68， ITGAX， and CTSS compared with the model group （P<0.05）. ConclusionSJGB effectively improved the lung function and attenuated lung tissue inflammation in the mouse model of COPD by modulating the lysosomal pathway and related genes including CD68， ITGAX， and CTSS.

Objective To examine the changing prevalence and antimicrobial resistance profiles of Burkholderia cepacia in 52 hospitals across China from 2015 to 2021.Methods A total of 9 261 strains of B.cepacia were collected from 52 hospitals between January 1,2015 and December 31,2021.Antimicrobial susceptibility of the strains was tested using Kirby-Bauer method or automated antimicrobial susceptibility testing systems according to a unified protocol.The results were interpreted according to the breakpoints released in the Clinical & Laboratory Standards Institute(CLSI)guidelines(2023 edition).Results A total of 9 261 strains of B.cepacia were isolated from all age groups,especially elderly patients.The proportion was 11.1％(1 032 strains)in children,significantly lower than the proportion in adults.About half(46.5％,4 310/9 261)of the strains were isolated from patients at least 60 years old and 42.3％(3 919/9 261)of the strains were isolated from young adults.Most isolates(71.1％)were isolated from sputum and respiratory secretions,followed by urine(10.7％)and blood samples(8.1％).B.cepacia isolates were highly susceptible to the five antimicrobial agents recommended in the CLSI M100 document(33rd edition,2023).B.cepacia isolates showed relatively higher resistance rates to meropenem and levofloxacin.However,the resistance rates to ceftazidime,trimethoprim-sulfamethoxazole,and minocycline remained below 8.1％.The percentage of B.cepacia strains resistant to levofloxacin was the highest compared to other antibiotics in any of the three age groups(from 12.4％in the patients＜18 years old to 20.6％in the patients aged 60 years or older).Conclusions B.cepacia is one of the clinically important non-fermenting gram-negative bacteria.Accurate and timely reporting of antimicrobial susceptibility test results and ongoing antimicrobial resistance surveillance are helpful for rational prescription of antimicrobial agents and proper prevention and control of nosocomial infections.

Objective To summarize the changing prevalence of carbapenem resistance in Enterobacterales based on the data of CHINET Antimicrobial Resistance Surveillance Program from 2015 to 2021 for improving antimicrobial treatment in clinical practice.Methods Antimicrobial susceptibility testing was performed using a commercial automated susceptibility testing system according to the unified CHINET protocol.The results were interpreted according to the breakpoints of the Clinical & Laboratory Standards Institute(CLSI)M100 31st ed in 2021.Results Over the seven-year period(2015-2021),the overall prevalence of carbapenem-resistant Enterobacterales(CRE)was 9.43％(62 342/661 235).The prevalence of CRE strains in Klebsiella pneumoniae,Citrobacter freundii,and Enterobacter cloacae was 22.38％,9.73％,and 8.47％,respectively.The prevalence of CRE strains in Escherichia coli was 1.99％.A few CRE strains were also identified in Salmonella and Shigella.The CRE strains were mainly isolated from respiratory specimens(44.23±2.80)％,followed by blood(20.88±3.40)％and urine(18.40±3.45)％.Intensive care units(ICUs)were the major source of the CRE strains(27.43±5.20)％.CRE strains were resistant to all the β-lactam antibiotics tested and most non-β-lactam antimicrobial agents.The CRE strains were relatively susceptible to tigecycline and polymyxins with low resistance rates.Conclusions The prevalence of CRE strains was increasing from 2015 to 2021.CRE strains were highly resistant to most of the antibacterial drugs used in clinical practice.Clinicians should prescribe antimicrobial agents rationally.Hospitals should strengthen antibiotic stewardship in key clinical settings such as ICUs,and take effective infection control measures to curb CRE outbreak and epidemic in hospitals.

Objective To characterize the changing species distribution and antibiotic resistance profiles of respiratory isolates in hospitals participating in the CHINET Antimicrobial Resistance Surveillance Program from 2015 to 2021.Methods Commercial automated antimicrobial susceptibility testing systems and disk diffusion method were used to test the susceptibility of respiratory bacterial isolates to antimicrobial agents following the standardized technical protocol established by the CHINET program.Results A total of 589 746 respiratory isolates were collected from 2015 to 2021.Overall,82.6％of the isolates were Gram-negative bacteria and 17.4％were Gram-positive bacteria.The bacterial isolates from outpatients and inpatients accounted for(6.0±0.9)％and(94.0±0.1)％,respectively.The top microorganisms were Klebsiella spp.,Acinetobacter spp.,Pseudomonas aeruginosa,Staphylococcus aureus,Haemophilus spp.,Stenotrophomonas maltophilia,Escherichia coli,and Streptococcus pneumoniae.Each microorganism was isolated from significantly more males than from females(P＜0.05).The overall prevalence of methicillin-resistant S.aureus(MRSA)was 39.9％.The prevalence of penicillin-resistant S.pneumoniae was 1.4％.The prevalence of extended-spectrum β-lactamase(ESBL)-producing E.coli and K.pneumoniae was 67.8％and 41.3％,respectively.The overall prevalence of carbapenem-resistant E.coli,K.pneumoniae,Enterobacter cloacae,Pseudomonas aeruginosa,and Acinetobacter baumannii was 3.7％,20.8％,9.4％,29.8％,and 73.3％,respectively.The prevalence of β-lactamase was 96.1％in Moraxella catarrhalis and 60.0％in Haemophilus influenzae.The H.influenzae isolates from children(＜18 years)showed significantly higher resistance rates to β-lactam antibiotics than the isolates from adults(P＜0.05).Conclusions Gram-negative bacteria are still predominant in respiratory isolates associated with serious antibiotic resistance.Antimicrobial resistance surveillance should be strengthened in clinical practice to support accurate etiological diagnosis and appropriate antimicrobial therapy based on antimicrobial susceptibility testing results.

Objective To evaluate the efficacy,safety and economy of vonoprazan in the treatment of post-endoscopic submucosal dissection(ESD)ulcer by rapid health technology assessment method,and to provide reference for clinical treatment decision.Methods PubMed,Cochrane Library,Embase,ScienceDirect,CNKI,WanFang Data databases and the official website of health technology assessment(HTA)agency were electronically searched to collect HTA reports,systematic reviews/Meta-analysis and pharmacoeconomic studies of vonoprazan in the treatment of post-ESD ulcer from inception to July 31,2024.Two researchers independently screened literature,extracted data,and comprehensively analyzed the results of the included literature on the basis of literature quality evaluation.Results A total of 8 studies were included,all were systematic reviews/Meta-analysis.In terms of effectiveness,compared with proton pump inhibitors(PPI),vonoprazan significantly increased the overall ulcer healing rate after ESD and more rapid reduction of ulcer area(P<0.05).The results of subgroup analysis showed that there was no significant difference in ulcer healing rate between vonoprazan and PPI treatment at 4 or 8 weeks after ESD(P>0.05).Vonoprazan significantly increased the rate of postoperative ulcer reduction in H.pylori positive patients compared with PPI(P<0.05).In terms of safety,compared with PPI,vonoprazan reduced the incidence of overall adverse events rate(P<0.05).The difference in the incidence of delayed bleeding and ulcer perforation between vonoprazan and PPIs showed no statistically significant difference.(P>0.05).Conclusion Vonoprazan demonstrated favorable efficacy and safety in the treatment of ESD ulcers,and further economic studies are warranted.

In April 2022, a patient with a huge soft tissue defect in left lower limb was treated in the Department of Hand Microsurgery, Xuzhou Renci Hospital. The defect was 49 cm×20 cm in size. A huge conjoined abdominal flap was designed with perforating branch of right lateral circumflex femoral artery and inferior epigastric artery as the vascular pedicles. The total length of the conjoined flap was 66 cm with the width of 9-13 cm. An ipsilateral ALTF was taken and it was combined with the conjoined flap in parallel to form an extra-large flap for wound reconstruction. Twenty-two months after surgery, the flap in left leg was not significantly bloated and without ulceration in left heel. The affected leg was not hindering the patient from walking and slow running. Lower Extremity Function Score (LEFS) was used to evaluate the affected leg and a score of 61 was achieved. Only linear scars were left on the donor sites in thighs and abdomen without dysfunction, and scored 4 of Vancouver Scar Scale (VSS).

Objective:To compare the therapeutic efficacy of the dual anteromedial and anterolateral approaches versus that of the anterior midline approach in the treatment of Wahlquist type C medial tibial plateau fractures accompanied by posterior column collapse.Methods:A retrospective study was conducted to analyze the 21 patients who had been treated for Wahlquist type C medial tibial plateau fractures plus posterior column collapse at The Fourth Orthopedic Ward, The 72nd Group Army Hospital of PLA between January 2019 and August 2023. The cohort included 13 males and 8 females, with an age of (43.3±6.7) years. The left side was involved in 14 fractures and the right side in 7 ones. The patients were divided into 2 groups based on their surgical approaches: a dual-approach group ( n=13) undergoing fixation via the dual anteromedial and anterolateral approaches, and a single-approach group ( n=8) undergoing fixation via the anterior midline approach. Comparative parameters included operative time, intraoperative blood loss, fracture healing time, quality of fracture reduction, medial proximal tibial angle (MPTA), incision complications, postoperative bone mass reduction quality (evaluated according to the Rasmussen anatomical criteria for tibial condyle fracture reduction), lateral tibial plateau instability, incidence of genu varum, and post-traumatic arthritis. Functional recovery of the lower limb joints was assessed at the final follow-up using the Merchant criteria. Results:No statistically significant differences were observed in the baseline characteristics between the 2 groups preoperatively, indicating comparability ( P>0.05). All patients were followed up for a mean duration of (38.1±11.3) months. The postoperative MPTA in the dual-approach group (86.8°±0.8°) was significantly larger than that in the single-approach group (85.5°±0.9°) ( P<0.05). Genu varum occurred in 1 patient in the dual-approach group and in 4 patients in the single-approach group, while lateral tibial plateau instability was observed in 1 patient in the dual-approach group and in 4 patients in the single-approach group, showing statistically significant differences between the 2 groups ( P<0.05). No statistically significant differences were found between the 2 groups regarding operative time, intraoperative blood loss, fracture healing time, quality of fracture reduction, incidence of incision complications, or incidence of post-traumatic arthritis ( P>0.05). At the final follow-up, no statistically significant difference was observed in the functional recovery of the lower limb joints assessed by the Merchant criteria between the 2 groups ( P>0.05). Conclusion:In the treatment of Wahlquist type C medial tibial plateau fractures accompanied by posterior column collapse, compared with the single anterior midline approach, the dual anteromedial and anterolateral approaches can restore more effectively the MPTA, and reduce the incidences of genu varum and lateral tibial plateau instability.
