		                        			ObjectiveTo investigate the distribution of traditional Chinese medicine (TCM) syndrome elements in type 2 diabetes mellitus (T2DM) patients based on maximum body mass index (maxBMI) and explore their association with complication risks. MethodsA retrospective cross-sectional study was used to collect clinical data from hospitalized T2DM patients, extracting age, gender, smoking history, alcohol consumption history, duration of disease, HbA1c level, complications, and TCM syndromes, and extracting the syndrome elements of disease location and disease nature based on their TCM syndromes. MaxBMI was calculated by telephone survey of patients' self-reported maximum body weight; patients with maxBMI ≥24 kg/m2 were classified into spleen-heat syndrome group, and those with maxBMI <24 kg/m2 were classified into consumptive-heat syndrome group. The distribution of TCM syndrome types and syndrome elements of patients in the two groups were analysed. Then the propensity score matching method was used to balance the baseline characteristics between the two groups and compare the differences in the distribution of syndrome types and syndrome elements and the risk of macrovascular and microvascular complications between the two groups. ResultsAmong the 1178 T2DM patients, syndrome elements in spleen-heat patients (1034 cases) were primarily located in the spleen (351 cases, 33.95%), liver (240 cases, 23.21%), and stomach (139 cases, 13.44%), while in consumptive-heat patients (144 cases), they were concentrated in the spleen (57 cases, 39.58%), liver (34 cases, 23.61%), and kidneys (17 cases, 11.81%); regarding syndrome elements of disease nature, spleen-heat patients were predominantly characterized by qi deficiency (481 cases, 46.52%), phlegm (353 cases, 22.73%), and dampness (241 cases, 23.31%), whereas consumptive-heat patients showed more qi deficiency (84 cases, 58.33%) and yin deficiency (44 cases, 30.56%). After propensity score matching, 132 cases were included in each group, and no statistically significant differences were observed in the distribution of syndrome elements of disease location between the two groups (P>0.05), but the phlegm element was significantly more prevalent in spleen-heat patients than in consumptive-heat patients (P = 0.006). Regarding the risk of complications, spleen-heat patients had a significantly higher risk of developing macrovascular complications compared to consumptive-heat patients (OR=2.04, P=0.010), while no significant differences were found between groups in the occurrence of microvascular complications (P>0.05). ConclusionThe spleen-heat T2DM patients show a more frequent syndrome element of disease nature of phlegm, and a higher risk of developing macrovascular complications compared to consumptive-heat patients.

		                        			ObjectiveTo construct a rat model of psoriasis with spleen deficiency and dampness obstruction syndrome (external dampness type), and evaluate the macroscopic manifestations and microscopic indicators of the model. MethodsTwenty-two SD rats were divided into normal group (n=3), common psoriasis group (n=5), spleen deficiency and dampness obstruction syndrome (external dampness type) group (n=7), and psoriasis with spleen deficiency and dampness obstruction syndrome (external dampness type) group (n=7). The spleen deficiency and dampness obstruction syndrome (external dampness type) rat model was established through 32-week exposure to an artificially simulated high-humidity environment, while the common psoriasis model was developed via 7-day topical application of imiquimod cream, and these two approaches were combined to construct a composite model of psoriasis with spleen deficiency and dampness obstruction syndrome (external dampness type). Rats in the normal group were housed under normal humidity conditions. The general state, tongue manifestation of rats were observed to evaluate the macroscopic syndrome manifestations; the microscopic syndrome manifestations of rats were evaluated through adipose tissue and liver tissue changes; the severity of psoriasis in rats was evaluated through skin pathological changes, psoriasis area and severity index (PASI), proliferating cell nuclear antigen (PCNA) expression and spleen tissue changes; changes in rat CD4+ interferon-γ+ cells (CD4+IFN-γ+ cells), CD4+ tumour necrosis factor-α+ cells (CD4+ TNF-α+ cells), and forkhead framing protein P3+ regulatory T cells (CD3+CD4+FoxP3+ Treg cells) were detected by flow cytometry. ResultsMacroscopically, both the spleen deficiency and dampness obstruction syndrome (external dampness type) group and psoriasis with spleen deficiency and dampness obstruction syndrome (external dampness type) group exhibited manifestations of spleen deficiency and dampness obstruction, including lethargy, huddling behavior, dull and disheveled fur, as well as soft or loose stools and perianal soiling in some individuals; both these two groups displayed enlarged tongue, swollen, and moist tongue texture, accompanied by slippery tongue surface. Microscopically, compared to the common psoriasis group, the psoriasis with spleen deficiency and dampness obstruction syndrome (external dampness type) group showed increased epididymal fat index (P<0.05); compared to the normal group and spleen deficiency and dampness obstruction syndrome (external dampness type) group, the psoriasis with spleen deficiency and dampness obstruction syndrome (external dampness type) group demonstrated significantly elevated spleen mass (P<0.05), while hepatic gross morphology and HE staining revealed no significant histopathological changes across all groups. Dorsal skin lesions were markedly exacerbated in the psoriasis with spleen deficiency and dampness obstruction syndrome (external dampness type) group when compared to those in common psoriasis group. Both the common psoriasis group and psoriasis with spleen deficiency and dampness obstruction syndrome (external dampness type) group exhibited significantly higher erythema scores, scaling scores, infiltration scores, PASI total scores, and proportions of CD3+CD4+FoxP3+Treg cells compared to the normal group and spleen deficiency and dampness obstruction syndrome (external dampness type) group (P<0.05), with pronounced PCNA-positive expression observed in the epidermal basal layer and dermis; the psoriasis with spleen deficiency and dampness obstruction syndrome (external dampness type) group displayed significantly increased proportions of CD4+TNF-α+cells compared to the spleen deficiency and dampness obstruction syndrome (external dampness type) group (P<0.05); whereas no significant differences were detected in CD4+IFN-γ+cell proportions among groups (P>0.05). ConclusionThe rat model of psoriasis with spleen deficiency and dampness obstruction syndrome (external dampness type) can be successfully constructed by artificially simulating a high-humidity environment combined with imiquimod induction.

		                        			Objective:To report the results of national surveillance on the distribution and antimicrobial resistance profile of clinical Gram-negative bacteria isolates from bloodstream infections in China in 2022.Methods:The clinical isolates of Gram-negative bacteria from blood cultures in member hospitals of national bloodstream infection Bacterial Resistant Investigation Collaborative System(BRICS)were collected during January 2022 to December 2022. Antibiotic susceptibility tests were conducted by agar dilution or broth dilution methods recommended by Clinical and Laboratory Standards Institute(CLSI). WHONET 5.6 and SPSS 25.0 software were used to analyze the data.Results:During the study period,9 035 strains of Gram-negative bacteria were collected from 51 hospitals,of which 7 895(87.4%)were Enterobacteriaceae and 1 140(12.6%)were non-fermenting bacteria. The top 5 bacterial species were Escherichia coli( n=4 510,49.9%), Klebsiella pneumoniae( n=2 340,25.9%), Pseudomonas aeruginosa( n=534,5.9%), Acinetobacter baumannii complex( n=405,4.5%)and Enterobacter cloacae( n=327,3.6%). The ESBLs-producing rates in Escherichia coli, Klebsiella pneumoniae and Proteus spp. were 47.1%(2 095/4 452),21.0%(427/2 033)and 41.1%(58/141),respectively. The prevalence of carbapenem-resistant Escherichia coli(CREC)and carbapenem-resistant Klebsiella pneumoniae(CRKP)were 1.3%(58/4 510)and 13.1%(307/2 340);62.1%(36/58)and 9.8%(30/307)of CREC and CRKP were resistant to ceftazidime/avibactam combination,respectively. The prevalence of carbapenem-resistant Acinetobacter baumannii(CRAB)complex was 59.5%(241/405),while less than 5% of Acinetobacter baumannii complex was resistant to tigecycline and polymyxin B. The prevalence of carbapenem-resistant Pseudomonas aeruginosa(CRPA)was 18.4%(98/534). There were differences in the composition ratio of Gram-negative bacteria in bloodstream infections and the prevalence of main Gram-negative bacteria resistance among different regions,with statistically significant differences in the prevalence of CRKP and CRPA( χ2=20.489 and 20.252, P<0.001). The prevalence of CREC,CRKP,CRPA,CRAB,ESBLs-producing Escherichia coli and Klebsiella pneumoniae were higher in provinicial hospitals than those in municipal hospitals( χ2=11.953,81.183,10.404,5.915,12.415 and 6.459, P<0.01 or <0.05),while the prevalence of CRPA was higher in economically developed regions(per capita GDP ≥ 92 059 Yuan)than that in economically less-developed regions(per capita GDP <92 059 Yuan)( χ2=6.240, P=0.012). Conclusions:The proportion of Gram-negative bacteria in bloodstream infections shows an increasing trend,and Escherichia coli is ranked in the top,while the trend of CRKP decreases continuously with time. Decreasing trends are noted in ESBLs-producing Escherichia coli and Klebsiella pneumoniae. Low prevalence of carbapenem resistance in Escherichia coli and high prevalence in CRAB complex have been observed. The composition ratio and antibacterial spectrum of bloodstream infections in different regions of China are slightly different,and the proportion of main drug resistant bacteria in provincial hospitals is higher than those in municipal hospitals.

		                        			AIM To investigate the effects of Ginkgo biloba extract on hearing function,cochlear morphology and autophagy-related protein expression in a rat model of presbycusis.METHODS Forty-five rats were randomly divided into the control group,the model group and the low,medium and high dose G.biloba extract groups(10,20 and 30 mg/kg),with 9 rats in each group.The rat model of presbycusis was established by intraperitoneal injection of 500 mg/kg D-galactose(D-gal).Eight weeks after the corresponding administration,the rats had their changes of hearing threshold detected by the auditory brainstem evoked potential(ABR);their morphological changes of cochlear hair cells,stria vascularis(SV)and spiral ganglion cells observed by HE staining;their number of hair cells inside and outside the cochlea detected by immunofluorescence staining;their ultrastructure changes of cochlear hair cells observed by transmission electron microscopy;and their expression of autophagy-related proteins in cochlea tissue detected by Western blot.RESULTS Compared with the control group,the model group displayed increased ABR threshold(P<0.01);more severely damaged inner and outer hair cells,spiral ganglion cells and SV,decreased SV thickness and numbers of spiral ganglion cells,inner and outer hair cells and autophagosomes(P<0.01);decreased protein expressions of Beclin1 and LC3 Ⅱ and ratio of LC3 Ⅱ/LC3 Ⅰ in cochlear tissue(P<0.01),and higher P62 protein expression(P<0.01).Compared with the model group,the medium and high dose G.biloba extract groups shared decreased ABR thresholds(P<0.01);improved morphology of inner and outer hair cells and SV in the cochlea,normalized,morphology of spiral ganglion cells,and increased SV thickness and the numbers of spiral ganglion cells,inner and outer hair cells and autophagosomes(P<0.05,P<0.01);increased protein expressions of Beclin1 and LC3 Ⅱ and the ratio of LC3 Ⅱ/LC3 Ⅰ in the cochlea(P<0.01),and decreased P62 protein expression(P<0.01).CONCLUSION The protective effects G.biloba extract on hearing function and cochlear cells in the rat model of presbycusis may be associated with the up-regulated expression of Beclin1 and LC3 Ⅱ proteins and down-regulated P62 protein expression in cochlear tissues.
