This study aims to explore the mechanism of Jiaotai Pills in treating depression based on metabolomics and network pharmacology. The chemical constituents of Jiaotai Pills were identified by UHPLC-Orbitrap Exploris 480, and the targets of Jiaotai Pills and depression were retrieved from online databases. STRING and Cytoscape 3.7.2 were used to construct the protein-protein interaction network of core targets of Jiaotai Pills in treating depression and the "compound-target-pathway" network. DAVID was used for Gene Ontology(GO) function and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analyses of the core targets. The mouse model of depression was established with chronic unpredictable mild stress(CUMS) and treated with different doses of Jiaotai Pills. The behavioral changes and pathological changes in the hippocampus were observed. UHPLC-Orbitrap Exploris 120 was used for metabolic profiling of the serum, from which the differential metabolites and related metabolic pathways were screened. A "metabolite-reaction-enzyme-gene" network was constructed for the integrated analysis of metabolomics and network pharmacology. A total of 34 chemical components of Jiaotai Pills were identified, and 143 core targets of Jiaotai Pills in treating depression were predicted, which were mainly involved in the arginine and proline, sphingolipid, and neurotrophin metabolism signaling pathways. The results of animal experiments showed that Jiaotai Pills alleviated the depression behaviors and pathological changes in the hippocampus of the mouse model of CUMS-induced depression. In addition, Jiaotai Pills reversed the levels of 32 metabolites involved in various pathways such as arginine and proline metabolism, sphingolipid metabolism, and porphyrin metabolism in the serum of model mice. The integrated analysis showed that arginine and proline metabolism, cysteine and methionine metabolism, and porphyrin metabolism might be the key pathways in the treatment of depression with Jiaotai Pills. In conclusion, metabolomics combined with network pharmacology clarifies the antidepressant mechanism of Jiaotai Pills, which may provide a basis for the clinical application of Jiaotai Pills in treating depression.

Objective:This study aims to discuss the diagnosis and treatment of pediatric appendicovesical fistula (AVF).Methods:A retrospective analysis was conducted on the clinical data of a pediatric patient with AVF admitted to our hospital in March 2023. The patient was a 6-year and 11-month old male who was hospitalized on March 21, 2023, due to difficulty urinating accompanied by diarrhea for two weeks. Computed tomography (CT) revealed bladder stones. The preoperative diagnosis was bladder stones. Transurethral cystoscopic lithotripsy with laser was performed under general anesthesia. Two weeks postoperatively, the child presented with recurrent symptoms of frequent urination, urinary pain, and diarrhea. Urine routine examination indicated a urinary tract infection. Over a month of antibiotic treatment was ineffective, and symptoms such as pneumaturia and fecaluria emerged, with exacerbation of diarrhea, suggesting the possibility of a fistulous tract between the child's intestine and bladder. Further bladder ultrasonography with contrast showed microbubbles of contrast medium leaking from the right posterior bladder wall into the intestinal tract. Enhanced magnetic resonance imaging (MRI) demonstrated a small, sharp tube-like shadow at the upper edge of the right posterior bladder, with a strip-like, significantly enhanced shadow within the lumen. The preoperative diagnosis was revised to appendicovesical fistula. During cystoscopic examination, a papillary-like protrusion was identified on the right lateral wall of the bladder, with no evident orificium fistulae or foreign body discharge noted at the protrusion site. Consequently, robot-assisted laparoscopic partial cystectomy, appendectomy, and lysis of adhesions were performed.Results:The patient was administered antibiotic for a 10-day course of anti-infection and a urinary catheter was maintained for 13 days. The patient recovered entirely and had been discharged after the removal of the urinary catheter. At an 11-month follow-up, there were no reported specific discomforts.Conclusions:Pediatric AVF is rare, and bladder contrast-enhanced ultrasonography and MRI are preferred for initial diagnostic evaluation. The diagnosis can be confirmed by specific clinical presentations such as intermittent pneumaturia and fecaluria, diarrhea with bladder stones. Laparoscopic surgery or robot-assisted laparoscopic surgery could be a feasible treatment option.

Objective To explore the effects of preoperative anxiety on intraoperative body temperature,adverse reactions during recovery and incision healing in elderly patients undergoing radical mastectomy under general anesthesia.Methods A total of 139 elderly patients who underwent radical mastectomy under general anesthesia in the Fourth Affiliated Hospital of Nanjing Medical University from January 2020 to December 2022 were selected as the study objects,and they were divided into the non-anxiety group(87 cases)and the anxiety group(52 cases)according to whether they were complicated with anxiety before surgery.The nasopharyngeal temperature before surgery,after 30 minutes,60 minutes,90 minutes of surgery and at the end of surgery,the ratio of intraoperative nasopharyngeal temperature<36.0℃,the ratio of perioperative blood loss>300 mL,the occurrence of adverse reactions during the recovery period and the incision healing of patients in the two groups were compared.Results There was no statistically significant difference in the nasopharyngeal temperature before surgery and after 30 minutes of surgery of patients between the two groups(P>0.05).After 60 minutes,90 minutes of surgery and the end of surgery,the nasopharyngeal temperatures of patients in the anxiety group were lower than those in the non-anxietey group,and the differences were statistically significant(P<0.05).There were statistically significant differences in the nasopharyngeal temperature at different times of patients in the two groups(P<0.05).The ratios of patients with intraoperative nasopharyngeal temperature<36.0℃and perioperative blood loss>300 mL in the anxiety group were higher than those in the non-anxiety group,and the differences were statistically significant(P<0.05).The incidence of delayed awakening,shivering reaction,and poor postoperative incision healing in the anxiety group were higher than those in the non-anxiety group,with statistically significant differences(P<0.05).Conclusion Elderly patients undergoing radical mastectomy under general anesthesia combined with anxiety show obvious temperature drop after 60 minutes of surgery,and perioperative blood loss has significantly increased,with a higher incidence of intraoperative hypothermia,adverse reactions during recovery and poor postoperative incision healing,which should arouse clinical attention.

AIM:To investigate the effect of paeoniflorin(PF)on TLR4/MyD88 signaling pathway in liver of rats with metabolic dysfunction-associated fatty liver disease.METHODS:SPF grade male SD rats were randomly divid-ed into four groups:normal control(NC)group,model control(MC)group,low-dose paeoniflorin(PL)group,and high-dose paeoniflorin(PH)group.The normal group was given standard diet,and the other three groups were given high-fat diet for 8 weeks.From the fifth week,rats in paeoniflorin groups were given low dose(25 mg·kg-1·d-1)or high dose(50 mg·kg-1·d-1)paeoniflorin for 4 weeks.Serum alanine aminotransferase(ALT),aspartate aminotransferase(AST),total cholesterol(TC)and triglyceride(TG)were measured by biochemical method.The levels of tumor necrosis factor(TNF)-α was detected by ELISA.Pathological change of the liver was detected with hematoxylin-eosin(HE)staining and oil red O staining,and evaluated semi-quantitatively with the nonalcoholic fatty liver disease activity score(NAS).The expres-sion levels of TLR4,MyD88 and phosphorylated nuclear factor(p-NF)-κB p65 in liver tissues were detected by immuno-histochemistry and Western blot.RESULTS:Compared with the NC group,rats in the MC group showed increased TC,TG,ALT,AST and TNF-α in serum(P<0.05),and more lipid droplets in hepatocytes and inflammatory cell infiltration in the portal area,with higher NAS,TLR4,MyD88 and p-NF-κB p65 proteins in liver tissue(P<0.05).However,pae-oniflorin could reduce TC,TG,ALT,AST and TNF-α in serum(P<0.05),improve histopathological changes of liver,decrease the NAS scoring(P<0.05),and inhibit hepatic TLR4/MyD88/p-NF-κB p65 expressions(P<0.05).CONCLU-SION:Paeoniflorin could improve the lipid metabolism disorder and reduce liver inflammation during MAFLD,and the latter effect might be in part related to the inhibition of TLR4/MyD88 signaling pathway.

Objective: To verify the feasibility and accuracy of the transanal multipoint full-layer puncture biopsy (TMFP) technique in determining the residual status of cancer foci after neoadjuvant therapy (nCRT) in rectal cancer. Methods: Between April 2020 and November 2022, a total of 78 patients from the Beijing Chaoyang Hospital of Capital Medical University, the Beijing Friendship Hospital of Capital Medical University, the Qilu Hospital of Shandong University, the Zhongnan Hospital of Wuhan University with advanced rectal cancer received TMFP after nCRT participated in this prospective multicenter trial. There were 53 males and 25 females, aged (M(IQR)) 61 (13) years (range: 35 to 77 years). The tumor distance from the anal verge was 5 (3) cm (range: 2 to 10 cm). The waiting time between nCRT and TMFP was 73 (26) days (range: 33 to 330 days). 13-point transanal puncture was performed with a 16 G tissue biopsy needle with the residual lesion as the center. The specimens were submitted for independent examination and the complications of the puncture were recorded. The consistency of TMFP and radical operation specimen was compared. The consistency of TMPF with clinical remission rates for the diagnosis of complete pathological remission was compared by sensitivity, specificity, negative predictive value, positive predictive value and accuracy. Statistical analysis between groups was performed using the χ² analysis, and a paired χ² test was used to compare diagnostic validity. Results: Before TMFP, clinical complete response (cCR) was evaluated in 27 cases. Thirty-six cases received in vivo puncture, the number of punctures in each patient was 13 (8) (range: 4 to 20), 24 cases of tumor residue were found in the puncture specimens. The sensitivity to judgment (100% vs. 60%, χ²=17.500, P<0.01) and accuracy (88.5% vs. 74.4%, χ²=5.125, P=0.024) of TMFP for the pathologic complete response (pCR) were significantly higher than those of cCR. Implement TMFP based on cCR judgment, the accuracy increased from 74.4% to 92.6% (χ²=4.026, P=0.045). The accuracy of the in vivo puncture was 94.4%, which was 83.3% of the in vitro puncture (χ²=1.382, P=0.240). Overall, the accuracy of TMFP improved gradually with an increasing number of cases (χ²=7.112, P=0.029). Conclusion: TMFP is safe and feasible, which improves the sensitivity and accuracy of rectal cancer pCR determination after nCRT, provides a pathological basis for cCR determination, and contributes to the safe development of the watch and wait policy.

Objective: To evaluate the recognition of acute respiratory infection (ARI) by a pretrained model based on electronic medical records (EMRs). Methods: 38 581 EMRs were obtained from Chongqing University Three Gorges Hospital in December 2021. Bidirectional encoder representation from transformers (BERT) pretrained model was used to identify ARI in EMRs. The results of medical professionals were considered as the gold standard to calculate the sensitivity, specificity, Kappa value, and area under the curve of the receiver operating characteristic (AUC). Results: There were 3 817 EMRs in the test set, with 1 200 ARIs. A total of 1 205 cases were determined as ARI by the model, with a sensitivity of 92.67% (1 112/1 200) and a specificity of 96.45% (2 524/2 617). The model identified ARI with similar accuracy in males and females (AUCs 0.95 and 0.94, respectively), and was more accurate in identifying ARI cases in those aged less than 18 than in adults 18-59 and adults 60 and older (AUCs 0.94, 0.89 and 0.94, respectively). The current model had a better identification of ARIs in outpatient patients than that in hospitalized patients, with AUCs of 0.74 and 0.95, respectively. Conclusion: The use of the BERT pretrained model based on EMRs has a good performance in the recognition of ARI cases, especially for the outpatients and juveniles. It shows a great potential to be applied to the monitoring of ARI cases in medical institutions.

Objective To investigate the prevalence of Schistosoma japonicum infection in wild mice in Shitai County, Anhui Province, so as to provide insights into precise control of the source of S. japonicum infections. Methods Wild mice were captured using the trapping method for three successive nights at snail-infested settings from Jitan Village of Jitan Township, and Shiquan Village and Xibai Village of Dingxiang Township, Shitai County, Anhui Province in June and October, 2018. All trapped wild mice were sacrificed and liver and mesenteric vein specimens were collected for detection of S. japonicum eggs using microscopy, while the fecal samples in mouse intestines were collected for identification of S. japonicum infections using Kato-Katz technique. In addition, the population density of trapped wild mice was estimated and the prevalence of S. japonicum infection was calculated in trapped wild mice. Results A total of 376 wild mice were trapped from three villages in Shitai County. The population density of trapped wild mice was 9.1% (376/4 124), and the prevalence of S. japonicum infection was 24.2% (91/376) in trapped wild mice. The highest prevalence of S. japonicum infection was detected in Shiquan Village of Dingxiang Township (30.1%), and the lowest prevalence was seen in Xibai Village of Dingxiang Township; however, there was no significant difference in the prevalence of S. japonicum infection in trapped wild mice among three villages (χ²= 4.111, P > 0.05). In addition, there was no significant difference in the prevalence of S. japonicum infection in wild mice captured between on June (26.8%, 34/127) and October (22.9%, 57/249) (χ² = 0.690, P = 0.406). The trapped wild mice included 6 species, including Rattus norvegicus, Niviventer niviventer, R. losea, Apodemus agrarius, Mus musculus and N. coning, and the two highest prevalence of S. japonicum infection was detected in R. losea (34.9%, 22/63) and R. norvegicus (31.2%, 44/141). Conclusions The prevalence of S. japonicum infections is high in wild mice in Shitai County, and there is a natural focus of schistosomiasis transmission in Shitai County.

Objective:To investigate the detection, epidemiological and clinical characteristics of human rhinovirus(HRV) in hospitalized children with respiratory tract infections.Methods:The study population comprised of 10 514 children with respiratory tract infections admitted to Department of Respiration, the Children′s Hospital of Soochow University, between January 2013 and December 2019.The nasopharyngeal aspirates and medical history were obtained by qualified medical personnel.Reverse transcription-polymerase chain reaction method was used to test HRV.Results:The total positive rate of human rhinovirus was 14.2%(1 493/10 514), and there was no significant difference between male and female( χ2=2.006, P=0.157). The positive rates from 2013 to 2019 were 9.7%, 14.6%, 19.1%, 18.6%, 18.1%, 11.0%, 11.4% respectively, and there were significant differences among these groups( χ2=116.580, P<0.001). HRV distributed throughout the year with a peak in summer and autumn(June to November), followed by spring, and the lowest in winter.The detection rates of HRV infection rates were 14.2%, 15.5%, 13.5% and 9.8% in the age group of 28 d~6 months, ~2 years, ~7 years and>7 years respectively, and there were significant differences among these age groups( χ2=16.124, P<0.001). The detection rate of HRV in children under 2 years was higher( χ2=7.711, P=0.005). The clinical characteristics of HRV infection were fever, cough, wheezing and even dyspnea.Bronchopneumonia had the highest percentage(68.9%), followed by bronchitis(13.2%). Compared with non-coinfection group, patients with coinfection with other viruses were more prone to wheezing and pulmonary rales( χ2=9.483, 10.821, P=0.024, 0.013), and coinfection with mycoplasma was more likely to cause fever and lobar pneumonia( χ2=51.585、96.060, P all<0.001); 57.8% presented leukocytosis, while 15.6% showed a higher CRP(>15 mg/ml). The increase of CRP and leukocytosis were more obvious in children under 2 years of age( χ2=26.097, 55.973, P all<0.001). Conclusion:HRV was a major viral pathogen of RTIs in recent 7 years, distributing throughout the year with a peak in summer and autumn, mainly involving children under 2 years of age.The clinical features were diverse, and the clinical symptoms were severe in childhood coinfections with other pathogens.

Objective To investigate the changing trends in the prevalence of schistosomiasis in Anhui Province from 2004 to 2020, so as to provide the evidence for formulating the schistosomiasis elimination strategy in the province. Methods The epidemiological data of schistosomiasis in Anhui Province from 2004 to 2020 were collected, and the trends in the endemic status of schistosomiasis were analyzed using a Joinpoint regression model. The trends in the prevalence of Schistosoma japonicum infections in humans, bovines and Oncomelania hupensis were measured in Anhui Province from 2004 to 2020 using average annual percent change (AAPC), and the correlations among the changing trends in the prevalence of S. japonicum infections in humans, bovines and O. hupensis snail status were evaluated using Pearson correlation analysis. Results The prevalence of S.japonicum human infections continued to decline in Anhui Province from 2004 to 2020, with an annual mean decline of 14.8% [AAPC = -14.8%, 95% confidential interval (CI): (-18.9%, -10.5%), P < 0.01]. The prevalence of S. japonicum infections continued to decline in bovines in Anhui Province from 2004 to 2015 [AAPC = -31.3%, 95%CI: (-35.1%, -27.2%), P < 0.01], and was 0 for 5 successive years from 2016 to 2020. During the period from 2004 to 2020, there was an annual mean decline of 0.7% in areas of snail habitats [AAPC = -0.7%, 95%CI: (-1.2%, 0.3%), P < 0.05] and an annual mean decline of 9.2% in the density of living snails [AAPC = -9.2%, 95%CI: (-18.3%, 1.0%), P = 0.08] in Anhui Province from 2004 to 2020, and an annual mean decline of 35.6% was found in the density of S. japonicum-infected snails [AAPC = -35.6%, 95%CI: (-49.2%, -18.3%), P < 0.01] from 2004 to 2012, with no infected snails detected in Anhui Province from 2013 to 2020. There were significant correlations in the prevalence of S. japonicum infections between humans and bovines (r = 0.959, P < 0.01), between the prevalence of S. japonicum human infections and the density of S. japonicum-infected snails (r = 0.823, P < 0.01) and between the prevalence of S. japonicum infections in bovines and the density of S. japonicum-infected snails (r = 0.902, P < 0.01). Conclusions The prevalence of S. japonicum infections appeared a decline in humans, bovines and O. hupensis in Anhui Province from 2004 to 2020, and significant correlations were found among the changing trends in the prevalence of S. japonicum human infections, the prevalence of S. japonicum bovine infections and the density of S. japonicum-infected O. hupensis snails. Because of a minor decline in the area of snail habitats and widespread distribution of O. hupensis, however, there is still a risk of schistosomiasis transmission, and precision control for schistosomiasis remains to be reinforced in Anhui Province.

Felids are the unique definitive host of Toxoplasma gondii. The intestine of felid is the only site for initiating Toxoplasma gondii sexual reproduction. T. gondii excretes millions of infectious oocysts from the intestine, which are the primary source of infection. There are many difficulties in developing vaccines and drugs to control oocyst excretion due to the lack of an appropriate experimental model. Here, we established an in vitro feline intestinal epithelial cell (IEC) infection system and an efficient animal model of T. gondii Chinese 1 genotype, Wh6 strain (TgCtwh6). The Kunming mice brain tissues containing TgCtwh6 cysts were harvested 42-day post-infection. The bradyzoites were co-cultured with cat IECs in vitro at a ratio of 1:10. Five 3-month-old domestic cats were orally inoculated with 600 cysts each. The oocysts were detected by daily observation of cat feces by microscopy and polymerase chain reaction. We found that the parasite adhered and invaded cat IECs in vitro, transformed into tachyzoites, and then divided to form rose-like structures. These parasites eventually destroyed host cells, escaped, and finished the asexual reproduction process. Schizonts associated with sexual reproduction have not been observed during development in vitro cultured cells. However, schizonts were detected in all infected cat intestinal epithelial cells, and oocysts were presented in all cat feces. Our study provides a feasible cell model and an efficient infection system for the following studies of T. gondii sexual reproduction, and also lays a foundation to develop drugs and vaccines for blocking excretion and transmission of oocysts.
