Objective To investigate the effect of Xiao Chaihu Decoction and Xiangsha Liujunzi Decoction on the changes of gastric mucosal pathological score and gastrointestinal hormones in patients with chronic atrophic gastritis(CAG)of liver stagnation and spleen deficiency type.Methods A total of 156 cases of CAG patients with liver stagnation and spleen deficiency syndrome were randomly divided into a control group and an observation group,78 cases in each group.The control group was treated with conventional western medicine,and the observation group was treated with Xiao Chaihu Decoction and Xiangsha Liujunzi Decoction on the basis of treatment for the control group.The course of treatment covered four weeks.The changes in the scores of traditional Chinese medicine(TCM)symptoms such as epigastric distention and pain,poor appetite,loose stools,limb weakness,belching and acid regurgitation,gastric mucosal pathological scores and serum levels of gastrointestinal hormones of motilin(MTL)and gastrin(GAS)in the two groups were observed before and after treatment.The negative conversion rate of Helicobacter pylori(Hp)in the two groups was compared,and the clinical efficacy and safety of the two groups were evaluated.Results(1)After four weeks of treatment,the total effective rate of the observation group was 93.59％(73/78),which was significantly higher than 82.05％(64/78)of the control group,and the difference between the two groups was statistically significant(P＜0.05).(2)After treatment,the scores of TCM symptoms such as epigastric distention and pain,poor appetite,loose stool,limb weakness,belching and acid regurgitation in the two groups were significantly decreased compared with those before treatment(P＜0.05),and the decrease in the observation group was significantly superior to that in the control group(P＜0.05).(3)After treatment,the pathological scores of gastric mucosa in the two groups were significantly decreased when compared with those before treatment(P＜0.05),and the decrease in the observation group was more significant than that in the control group(P＜0.01).(4)After four weeks of treatment,the negative conversion rate of Hp in the observation group was 91.03％(71/78),which was significantly higher than that in the control group(75.64％,59/78),and the difference between the two groups was statistically significant(P＜0.05).(5)After treatment,the level of serum GAS in the two groups was significantly decreased(P＜0.05)and the serum MTL level was significantly increased compared with that before treatment(P＜0.05);the decrease of serum GAS level and the increase of serum MTL level in the observation group were significantly superior to those in the control group(P＜0.05).(6)There were no obvious abnormalities in the routine test of blood,urine,stool,kidney function,and liver function,electrocardiograph and other safety indicators during the treatment of the two groups of patients,no adverse reactions such as dizziness,rash and chest distress occurred either,with high safety.Conclusion Xiao Chaihu Decoction combined with Xiangsha Liujunzi Decoction exerts a significant therapeutic effect on GAS of liver stagnation and spleen deficiency type,which can effectively relieve the clinical symptoms,improve the pathological changes of gastric mucosa and promote Hp negative conversion.The therapeutic mechanism may be related to the regulation of gastrointestinal hormone levels.

Objective To investigate the structural characteristics of intestinal flora in children with sepsis and its association with inflammatory response.Methods A prospective cohort study was conducted.The children with sepsis who were admitted from December 2021 to January 2023 were enrolled as the sepsis group,and the children with non-sepsis who were admitted during the same period were enrolled as the non-sepsis group.The two groups were compared in terms of the distribution characteristics of intestinal flora,peripheral white blood cell count(WBC),C reactive protein(CRP),and cytokines,and the correlation of the relative abundance of fecal flora with WBC,CRP,and cytokines was analyzed.Results At the genus level,compared with the non-sepsis group,the sepsis group had significantly lower relative abundance of Akkermansia,Ruminococcus,and Alistipes and significantly higher relative abundance of Enterococcus,Streptococcus,and Staphylococcus(P<0.05).At the phylum level,Proteobacteria was the dominant phylum(37.46%)in the group of children with a score of≤70 from the Pediatric Critical Illness Score(PICS),and Firmicutes was the dominant phylum in the group of children with a score of 71-80 or 81-90 from the PICS(72.20%and 43.88%,respectively).At the genus level,among the 18 specimens,5 had a relative abundance of>50%for a single flora.Compared with the non-sepsis group,the sepsis group had significant higher levels of WBC,CRP,interleukin-6(IL-6),interleukin-10(IL-10),and tumor necrosis factor-α(P<0.05).The Spearman's rank correlation analysis showed that at the genus level,the relative abundance of Ruminococcus,Alistipes,and Parasutterella in the sepsis group was negatively correlated with the levels of WBC,CRP,and IL-6(P<0.05);the relative abundance of Enterococcus was positively correlated with the CRP level(P<0.01);the relative abundance of Streptococcus and Staphylococcus was positively correlated with the levels of CRP and IL-6(P<0.05);the relative abundance of Streptococcus was positively correlated with WBC(P<0.05).Conclusions Intestinal flora disturbance is observed in children with sepsis,and its characteristics vary with the severity of the disease.The structural changes of intestinal flora are correlated with inflammatory response in children with sepsis.

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 study the localization value of stereoelectroencephalography (SEEG) in refractory epilepsy associated with tuberous sclerosis complex (TSC), and to analyze the prognosis related factors.Methods:A case control study.Data of 66 patients with TSC-related refractory epilepsy who underwent SEEG placement at the Epilepsy Center of Tsinghua University Yu-Quan Hospital from January 2014 to March 2023 were retrospectively analyzed, including medical history, seizure semiology, scalp electroencephalogram (EEG), imaging, and SEEG findings.Patients were divided into a seizure-free group and a seizure group according to the seizures after surgery. t/ χ2 test was used to compare the relationship between age of onset, age of surgery, duration of epilepsy, genetic findings, seizure symptoms, scalp EEG characteristics, SEEG placement protocol and prognosis. Results:A total of 66 patients met the enrollment criteria, of whom 55 patients were seizure-free after surgery (seizure-free group), and 11 patients still had seizures (seizure group).Among the 66 patients, there were 46 males and 20 females; the age of onset was (21.72±30.01) months; the age of SEEG surgery was (6.79±5.12) years; the duration of epilepsy was (4.98±4.11) years.SEEG results showed that seizures started with a single tuber in 43 patients (64.4%), seizures started with 2 or more tubers in one hemisphere in 16 patients, and 7 patients had bilateral multi-tubers or the pathogenic tuber(s) could not be identified.The following factors were found to be associated with prognosis: early age of surgery ( t=-3.463, P<0.01), ictal scalp EEG with a definite lateralization ( χ2=7.876, P<0.05), and the concordance of interictal and ictal EEG ( χ2=6.821, P<0.05).The age of onset, duration of epilepsy, seizure type and symptom, genetic findings, and SEEG placement protocol were not significantly correlated with prognosis.The results of SEEG identified that onset with a single tuber revealed a better postoperative outcome. Conclusions:This study confirms the safety and efficacy of SEEG in TSC-related refractory epilepsy, and also finds that ictal EEG is uniquely valuable in guiding SEEG placement for TSC-related refractory epilepsy, which can help us better select patients with TSC-related refractory epilepsy who are suitable for SEEG placement.

Objective: To analyze the prevalence and the risk factors of fungal sepsis in 25 neonatal intensive care units (NICU) among preterm infants in China, and to provide a basis for preventive strategies of fungal sepsis. Methods: This was a second-analysis of the data from the "reduction of infection in neonatal intensive care units using the evidence-based practice for improving quality" study. The current status of fungal sepsis of the 24 731 preterm infants with the gestational age of <34⁺⁰ weeks, who were admitted to 25 participating NICU within 7 days of birth between May 2015 and April 2018 were retrospectively analyzed. These preterm infants were divided into the fungal sepsis group and the without fungal sepsis group according to whether they developed fungal sepsis to analyze the incidences and the microbiology of fungal sepsis. Chi-square test was used to compare the incidences of fungal sepsis in preterm infants with different gestational ages and birth weights and in different NICU. Multivariate Logistic regression analysis was used to study the outcomes of preterm infants with fungal sepsis, which were further compared with those of preterm infants without fungal sepsis. The 144 preterm infants in the fungal sepsis group were matched with 288 preterm infants in the non-fungal sepsis group by propensity score-matched method. Univariate and multivariate Logistic regression analysis were used to analyze the risk factors of fungal sepsis. Results: In all, 166 (0.7%) of the 24 731 preterm infants developed fungal sepsis, with the gestational age of (29.7±2.0) weeks and the birth weight of (1 300±293) g. The incidence of fungal sepsis increased with decreasing gestational age and birth weight (both P<0.001). The preterm infants with gestational age of <32 weeks accounted for 87.3% (145/166). The incidence of fungal sepsis was 1.0% (117/11 438) in very preterm infants and 2.0% (28/1 401) in extremely preterm infants, and was 1.3% (103/8 060) in very low birth weight infants and 1.7% (21/1 211) in extremely low birth weight infants, respectively. There was no fungal sepsis in 3 NICU, and the incidences in the other 22 NICU ranged from 0.7% (10/1 397) to 2.9% (21/724), with significant statistical difference (P<0.001). The pathogens were mainly Candida (150/166, 90.4%), including 59 cases of Candida albicans and 91 cases of non-Candida albicans, of which Candida parapsilosis was the most common (41 cases). Fungal sepsis was independently associated with increased risk of moderate to severe bronchopulmonary dysplasia (BPD) (adjusted OR 1.52, 95%CI 1.04-2.22, P=0.030) and severe retinopathy of prematurity (ROP) (adjusted OR 2.55, 95%CI 1.12-5.80, P=0.025). Previous broad spectrum antibiotics exposure (adjusted OR=2.50, 95%CI 1.50-4.17, P<0.001), prolonged use of central line (adjusted OR=1.05, 95%CI 1.03-1.08, P<0.001) and previous total parenteral nutrition (TPN) duration (adjusted OR=1.04, 95%CI 1.02-1.06, P<0.001) were all independently associated with increasing risk of fungal sepsis. Conclusions: Candida albicans and Candida parapsilosis are the main pathogens of fungal sepsis among preterm infants in Chinese NICU. Preterm infants with fungal sepsis are at increased risk of moderate to severe BPD and severe ROP. Previous broad spectrum antibiotics exposure, prolonged use of central line and prolonged duration of TPN will increase the risk of fungal sepsis. Ongoing initiatives are needed to reduce fungal sepsis based on these risk factors.

OBJECTIVE: To explore the relationship between serum lipoprotein-associated phospholipase A2 (Lp-PLA2) level and the risk of acute ischemic stroke (AIS) recurrence in hypertensive patients. METHODS: This retrospective case-control study was conducted among 211 hypertensive patients with AIS treated in Foshan First People's Hospital, including 35 patients with recurrence of AIS during the 1-year follow-up as confirmed by head CT/MR. In the overall patients, 60 had grade 1 hypertension (including 5 recurrent cases), 76 had grade 2 hypertension (with 11 recurrent cases), and 75 had grade 3 hypertension (with 19 recurrent cases). Univariate analysis, multivariate logistic regression analysis, trend analysis, and smooth curve fitting analysis were performed to explore the correlation between serum Lp-PLA2 level within 24 h after admission and the risk of AIS recurrence. The predictive efficacy of serum Lp-PLA2 level for AIS recurrence in different hypertension grades was evaluated using ROC curve analysis. RESULTS: Serum Lp-PLA2 level, age, NIHSS score at admission, mRS scores at 7 days, homocysteine level and smoking status differed significantly between patients with and without AIS recurrence (P < 0.05). After adjustment for confounding factors, multivariate regression analysis showed that the highest tertile of Lp-PLA2 level was associated with a 4.13-fold increase of AIS recurrence risk compared with the lowest tertile (OR=5.13, 95% CI: 1.35-19.40), and each 1 ng/mL increase of Lp-PLA2 level was associated with a 1% increase of AIS recurrence risk (OR= 1.01, 95% CI: 1.01-1.02). Serum Lp-PLA2 level was shown to positively correlate with AIS recurrence risk, and in patients with grade 3 hypertension, its areas under the ROC curve for predicting AIS recurrence was 0.869 with a specificity of 0.893 and a sensitivity of 0.737. CONCLUSION Serum Lp-PLA2 concentration is an independent risk factor and potentially an effective predictor for AIS recurrence in patients with grade 3 hypertension.

ObjectiveTo investigate the tumor-suppressing effect of Shenqi Yiliu prescription combined with cisplatin in hepatoma H22-bearing mice based on the phosphatase and tensin homolog deleted on chromosome ten （PTEN）/phosphatidylinositol-3-kinase （PI3K）/protein kinase B （Akt） pathway. MethodH22-bearing mice were prepared and randomized into model group， cisplatin group， and cisplatin combined with high-， medium-， and low-dose Shenqi Yiliu prescription groups， with 10 mice in each group. Another 10 healthy mice were randomly selected as normal group. Shenqi Yiliu prescription was given by gavage with the high， medium， low dose of 54.06， 27.03， 13.515 g·kg^-1·d^-1， respectively， and cisplatin （2.5 mg·kg^-1） was administered by intraperitoneal injection， twice a week. Normal group and model group received normal saline. After 13 days of treatment， mice were killed and the tumor inhibition rate was calculated. The pathomorphological changes of tumor were observed based on hematoxylin-eosin （HE） staining， and enzyme-linked immunosorbent assay （ELISA） and immunofluorescence method were used to detect the content of cyclin-dependent kinase inhibitor 1A （p21） and cyclin-dependent kinase inhibitor 1B （p27） in tumor tissue of mice. The levels of PTEN， PI3K and phosphorylated protein kinase B （p-Akt） in tumor tissue were measured by Western blot. ResultCompared with the model group， cisplatin alone and cisplatin in combination with the high-， medium-， and low-dose Shenqi Yiliu prescription decreased tumor mass （P<0.05）， particularly the cisplatin in combination with the high-dose Shenqi Yiliu prescription. Necrosis of the tumor tissue was observed in each group， especially the cisplatin combined with high-dose Shenqi Yiliu prescription group. As compared with the model group， cisplatin alone and cisplatin in combination with the high-， medium-， and low-dose Shenqi Yiliu prescription raised the expression of p21， p27， and PTEN （P<0.05） and lowered the expression of PI3K and p-Akt （P<0.05）， particularly the cisplatin in combination with high-dose Shenqi Yiliu prescription. ConclusionShenqi Yiliu prescription may regulate the expression of key molecules in PTEN/PI3K/Akt signaling pathway， thereby upregulating the expression of downstream proliferation inhibitors p21 and p27， further suppressing the tumor in H22-bearing mice， and enhancing the effect of chemotherapy.

Objective:To evaluate the diagnostic value of 1, 3-β-D glucan (BDG), mannan IgM antibody (Mn-IgM) and mannan IgG antibody (Mn-IgG) in invasive candidiasis and to compare the differences in the diagnostic capability of serological markers used alone or in combination.Methods:Serum samples of 126 patients with invasive candidiasis and 104 healthy people who took physical examination during the same period were collected. BDG was detected by dynamic chromogenic method, and Mn-IgM and Mn-IgG were detected by ELISA. The sensitivity, specificity, positive predictive value, negative predictive value, Youden index, coincidence rate and Kappa value of the three serological markers used alone or in combination in the diagnosis of invasive candidiasis were analyzed and compared. The receiver operating characteristic (ROC) curves were drawn and the areas under the curves (AUCs) were calculated.Results:The levels of BDG, Mn-IgM and Mn-IgG in patients with invasive candidiasis were significantly higher than those in healthy people ( P<0.01). The sensitivity, specificity, Kappa value and AUC of BDG were 48.41%, 92.31%, 0.389 and 0.842. The sensitivity, specificity, Kappa value and AUC of Mn-IgM were 64.29%, 91.35%, 0.540 and 0.829. The sensitivity, specificity, Kappa value and AUC of Mn-IgG were 27.78%, 95.19%, 0.214 and 0.737. The sensitivity, specificity, Kappa value and AUC of BDG+ Mn-IgM were 76.19%, 88.46%, 0.637 and 0.921. The sensitivity, specificity, Kappa value and AUC of BDG+ Mn-IgG were 59.52%, 91.35%, 0.491 and 0.856. The sensitivity, specificity, Kappa value and AUC of Mn-IgM+ Mn-IgG were 69.84%, 90.38%, 0.588 and 0.891. The sensitivity, specificity, Kappa value and AUC of BDG+ Mn-IgM+ Mn-IgG were 80.16%, 88.46%, 0.679 and 0.922. Conclusions:The sensitivity of Mn-IgM was higher than that of BDG and Mn-IgG in the diagnosis of invasive candidiasis. When the serological biomarkers were used in combination, BDG+ Mn-IgM and BDG+ Mn-IgM+ Mn-IgG had relatively high Kappa value and AUC, showing high accuracy. The clinical diagnostic value of multiple serological biomarkers used in combination was significantly higher than that of any serological biomarkers used alone. Early combined detection and continuous monitoring of multiple serological biomarkers in patients with high risk of invasive candidiasis could be used clinically to adjust antifungal treatment strategies timely.
