OBJECTIVE To investigate the ameliorative effect of ursolic acid on skin inflammation in rats with allergic contact dermatitis （ACD）， and explore its mechanism of action based on the Notch1/hairy and enhancer of split 1 （Hes1） signaling pathway. METHODS The ACD model was established by skin application of 2， 4-dinitrochlorobenzene. Forty successfully modeled rats were randomly divided into model control group （MC group）， ursolic acid low-dose group （UA-L group， 50 mg/kg）， ursolic acid high-dose group （UA-H group， 100 mg/kg）， and ursolic acid high-dose+Notch1 activator group （UA-H+Jagged1 group， 100 mg/kg ursolic acid+50 ng/kg Jagged1）， with 10 rats in each group. Another 10 rats with only hair shedding were selected as the normal control group. Rats in the administration groups were given the corresponding dose of ursolic acid intragastrically or/and Jagged1 by intraperitoneal injection once a day for 14 consecutive days. Twenty-four hours after the last treatment， the skin inflammation status and dermatitis scores of rats in each group were detected. The levels of interleukin-6 （IL-6）， IL-17 and IL-10 in serum and skin tissue were detected by enzyme-linked immunosorbent assay. Hematoxylin-eosin staining was used to detect the pathological morphology of the skin tissue. Immunohistochemical staining and immunoblotting assay were used to detect the protein expressions of Notch1 and Hes1 in skin tissues. RESULTS Compared with the MC group， both the UA-L group and UA-H group exhibited significantly lower dermatitis scores， along with varying degrees of reduction in histopathological skin damage such as inflammatory cell infiltration. Additionally， the levels of IL-6 and IL-17 in serum and skin tissues were markedly decreased， while the levels of IL-10 were significantly increased in both groups； protein expressions of Notch1 and Hes1 were decreased significantly （P＜0.05）， and the improvements in the aforementioned indicators were more significant in the UA-H group （P＜0.05）. Jagged1 could significantly weaken the improvement effects of UA-H on the above indicators （P＜0.05）. CONCLUSIONS Ursolic acid may attenuate the expression of pro-inflammatory cytokines and enhance the expression of anti-inflammatory factors by blocking Notch1/Hes1 signaling pathway， thereby improving dermatitis symptoms in ACD rats.

Background::Clinical opportunistic screening is a cost-effective cancer screening modality. This study aimed to establish an easy-to-use diagnostic model serving as a risk stratification tool for identification of individuals with malignant gastric lesions for opportunistic screening.Methods::We developed a questionnaire-based diagnostic model using a joint dataset including two clinical cohorts from northern and southern China. The cohorts consisted of 17,360 outpatients who had undergone upper gastrointestinal endoscopic examination in endoscopic clinics. The final model was derived based on unconditional logistic regression, and predictors were selected according to the Akaike information criterion. External validation was carried out with 32,614 participants from a community-based randomized controlled trial.Results::This questionnaire-based diagnostic model for malignant gastric lesions had eight predictors, including advanced age, male gender, family history of gastric cancer, low body mass index, unexplained weight loss, consumption of leftover food, consumption of preserved food, and epigastric pain. This model showed high discriminative power in the development set with an area under the receiver operating characteristic curve (AUC) of 0.791 (95% confidence interval [CI]: 0.750–0.831). External validation of the model in the general population generated an AUC of 0.696 (95% CI: 0.570–0.822). This model showed an ideal ability for enriching prevalent malignant gastric lesions when applied to various scenarios.Conclusion::This easy-to-use questionnaire-based model for diagnosis of prevalent malignant gastric lesions may serve as an effective prescreening tool in clinical opportunistic screening for gastric cancer.

Aim To design and synthesize a series of phenylacetamide derivatives with different substituted phenylacetic acid as raw materials,and to investigate the protective effects of the compound on the damage of pancreatic β cells induced by palmitate acid(PA).Methods Min6 cells were cultured and divided into B blank control group,PA treatment group and PA+compounds group.The viability of Min6 cells was de-tected by CCK-8.The protein expressions of TXNIP and NLRP3 were observed by Western blot.MDA con-tent and SOD activity were detected by MDA and SOD kit.The insulin secretion of Min6 islet cells was meas-ured with insulin ELISA kit.Results A total of 10 phenylacetamide derivatives were designed and synthe-sized.Their structures were confirmed by 1H NMR and ESI-MS.Pharmacological activity study showed that most of the compounds had protective effects on islet βcells,among which LY-6 and LY-8 had stronger pro-tective effects than PA model group,with the cell via-bility of 61.4％,and LY-6 had the highest cell activi-ty,reaching to 104.9％.Compared with PA group,the protein expression of TXNIP and NLRP3 decreased in LY-6 and LY-8 groups,MDA content decreased and SOD activity increased,and insulin secretion of Min6 cell increased.Conclusions LY-6 and LY-8 inhibit TXNIP expression and decrease the activation of NL-RP3 inflammasome,and decrease the production of MDA and increase SOD activity,and thus reducing is-let β cells apoptosis and increasing insulin secretion.Therefore,the compound LY-6 could serve as a poten-tial anti-diabetic new chemical entity.

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 understand the current rehabilitation status and existing problems of patients with degenerative scoliosis after surgery, and analyze the needs of continuous health education for patients.Methods:A total of 15 patients with degenerative scoliosis undergoing surgical treatment in Nanjing Drum Tower Hospital, Affiliated Hospital of Medical School, Nanjing University from December 2021 to June 2022 were selected by the convenient sampling method. The semi-structured interview was used to understand the patient's feelings on the operation effect, experience on the postoperative life impact, thoughts on rehabilitation exercise, self-cognition of home status and future development planning. Based on the rooted theory, Colaizzi 7-step analysis was applied to extract the topic.Results:The four themes related to the continuous health education needs of patients with degenerative scoliosis after surgery were summarized, which were unacceptable movement limitation of lower back or lower extremity, blind area of continuous rehabilitation exercise, lack of knowledge of self-management of spinal disease after surgery and need for social and psychological support.Conclusions:Patients with degenerative scoliosis lack of postoperative rehabilitation knowledge and skills, and the need for health education is strong. Medical staff can meet the patients' transitional care needs by educating them to adapt to the current situation, providing personalized rehabilitation goals, guiding patients in managing risk factors that affect their own rehabilitation and improving social and family support systems, thereby promoting rapid recovery of patients.

Objective:To analyze the distribution characteristics of Rh phenotype in pregnant and postpartum women in Chongqing area,and to explore the clinical significance of Rh phenotype in pregnant and postpartum women and the feasibility of Rh phenotype compatible blood transfusion.Methods:The ABO blood group and Rh phenotype of 65 161 pregnant and postpartum women were detected by microcolumn gel method,and 48 122 males in the same period were taken as controls.The data were analyzed by Chi-square test.Results:There were 112 870 cases(99.64％)of RhD+in 113 283 samples.In RhD+cases,CCDee(48.39％)and CcDEe(32.88％)were the main phenotypes.The first case of D--phenotype in Chongqing area was detected.413 cases(0.36％)of RhD-were detected,with ccdee(52.78％)and Ccdee(33.41％)as the main phenotypes.Compared with RhD-group,RhD+group showed statistically significant difference in Rh phenotype distribution(P＜0.01).Among 65 161 maternal samples,the positive rate of 5 antigens of Rh blood group from high to low was D＞e＞C＞c＞E,and there was no significant difference compared with male samples(P＞0.05).There was no significant difference in the distribution of Rh phenotype between males and pregnant/postpartum women,as well as between pregnant/postpartum women with different ABO blood groups(P＞0.05).In pregnant and postpartum women,there was no significant difference in distribution of Rh phenotype among the normal pregnancy population,the population with adverse pregnancy history,the population using human assisted reproductive technology(ART)and the population with infertility(P＞0.05).There was no significant difference in the distribution of Rh phenotype between the 4 populations mentioned above and the inpatients in the local general Grade A hospitals and the blood donors(P＞0.05).In RhD positive pregnant and postpartum women,the probability of finding compatible blood for CcDEe phenotype was 100％,the probability of finding compatible blood for CCDee,CcDee and CCDEe phenotypes was 45％-60％,the probability of finding compatible blood for ccDEE,ccDEe and CcDEE phenotypes was 5％-10％,and the probability of finding compatible blood for other phenotypes was lower than 0.5％.The supply of blood with CCDee and ccDEE phenotypes can meet the compatible transfusions requirements of 7 Rh phenotypes in more than 99％of patients.Conclusion:Rh phenotype detection should be carried out for pregnant and postpartum women,and it is feasible to carry out Rh phenotype-matched or compatible blood transfusion for pregnant and postpartum women who need blood transfusion.

Background: AMP-activated protein kinase (AMPK) is a key enzyme for cellular energy homeostasis and improves metabolic disorders. Brown and beige adipose tissues exert thermogenesis capacities to dissipate energy in the form of heat. Here, we investigated the beneficial effects of the antioxidant alpha-lipoic acid (ALA) in menopausal obesity and the underlying mechanisms. Methods: Female Wistar rats (8 weeks old) were subjected to bilateral ovariectomy (Ovx) and divided into four groups: Sham (n=8), Ovx (n=11), Ovx+ALA2 (n=10), and Ovx+ALA3 (n=6) (ALA 200 and 300 mg/kg/day, respectively; gavage) for 8 weeks. 3T3-L1 cells were used for in vitro study. Results: Rats receiving ALA2 and ALA3 treatment showed significantly lower levels of body weight and white adipose tissue (WAT) mass than those of the Ovx group. ALA improved plasma lipid profiles including triglycerides, total cholesterol, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol. Hematoxylin & eosin staining of inguinal WAT showed that ALA treatment reduced Ovx-induced adipocyte size and enhanced uncoupling protein 1 (UCP1) expression. Moreover, plasma levels of irisin were markedly increased in ALA-treated Ovx rats. Protein expression of brown fat-specific markers including UCP1, PRDM16, and CIDEA was downregulated by Ovx but markedly increased by ALA. Phosphorylation of AMPK, its downstream acetyl-CoA carboxylase, and its upstream LKB1 were all significantly increased by ALA treatment. In 3T3-L1 cells, administration of ALA (100 and 250 μM) reduced lipid accumulation and enhanced oxygen consumption and UCP1 protein expression, while inhibition of AMPK by dorsomorphin (5 μM) significantly reversed these effects. Conclusion ALA improves estrogen deficiency-induced obesity via browning of WAT through AMPK signaling.

Objective:To investigate the value of transrectal ultrasonography(TRUS)in the detection of clinically significant prostate cancer(CsPCa)in patients with intravesical prostatic protrusion(IPP).Methods:We retrospectively analyzed the data on 128 patients undergoing TRUS-guided prostate biopsy in the General Hospital of Eastern Theater Command and Jiangsu Province Hospi-tal from January 2019 to December 2022.We measured the size of and graded IPP,compared the clinicopathological and ultrasono-graphic features of the patients in the CsPCa group(Gleason score≥7)and those in the control group(Gleason score<7),and ana-lyzed the correlation of the IPP grades with the detection rate of CsPCa by multivariate logistic regression analysis.Results:The prostate volume was significantly higher in the CsPCa group than in the control([51.3±12.1]vs[43.5±11.3]ml,P<0.05),whilethe PSAdensity(PSAD)remarkablylowerin the former than in the latter([0.45±1.92]vs[0.59±2.14]ng/ml,P<0.05)and so was the detection rate of CsPCa in the patients with IPP grade3 than in those with IPP grades0,1 and2(56.0%vs 85.4%,87.1%and 80.6%,P<0.05).Spearman correlation analysis showed that the Gleason score was correlated positively with the prostate volume(r=0.612)but negatively with PSAD(r=-0.735)and the IPP grade(r=-0.619)(P<0.05).Logis-tic regression analysis indicated that IPP grade3(OR:0.690,95%CI:0.380-0.995,P=0.032)was an independent protective factor for CsPCa.Conclusion:CsPCa is significantly correlated with the IPP grade,and the detection rate of CsPCa by TRUS-guided biopsy is lower in patients with IPP grade 3 than in those with IPP grades 0-2.Therefore,special attention should be paid to false negative probability in case of high-grade IPP.
