OBJECTIVE To evaluate the clinical efficacy and safety of Jianwei xiaoshi oral liquid in the treatment of functional dyspepsia （FD） in children， and provide evidence-based basis for clinical use of the drug. METHODS Retrieved from CNKI， VIP， Wanfang， CBM， Cochrane Library and PubMed， randomized controlled trials （RCTs） about Jianwei xiaoshi oral liquid in the treatment of FD in children were collected from the inception to Apr. 2024. The control group was treated with conventional western drugs （including gastrointestinal motion-promoting， antacids or acid-suppressing drugs）， and the trial group was treated with Jianwei xiaoshi oral liquid alone or combined with conventional Western drugs （drug dosage and course of treatment were the same as the control group）. Meta-analysis was performed using RevMan 5.3 software after quality evaluation with the Cochrane risk bias assessment tool 6.1. RESULTS Totally 16 literature were employed which included 1 962 patients. The results of meta-analysis showed that the total clinical effective rate of Jianwei xiaoxi oral liquid in the treatment of FD in children of trial group was significantly higher than that of the control group [RR＝1.18， 95%CI （1.13， 1.22）， P＜0.000 01]. In this study， subgroup analysis was conducted on the usage and dosage， course of treatment， and combination or not in trial group， as well as the type of conventional Western drugs. The results showed that the total clinical effective rate of trial group was significantly higher than that of control group； the relief time of abdominal distension and abdominal pain in trial group [MD＝－2.54， 95%CI （－3.10， －1.98）]， loss of appetite relief time [MD＝－2.12， 95%CI （－2.63， －1.61）]， nausea and vomiting relief time [MD＝－1.70， 95%CI （－2.27， －1.14）]， and belching relief time [MD＝－1.61， 95%CI （－2.44， －0.78）] were shorter than that of the control group significantly （P＜0.05）. In addition， compared with control group， the levels of gastrin [SMD＝1.63， 95%CI （0.98， 2.29）] and motilin [SMD＝2.06， 95%CI （1.58， 2.54）] as well as gastric antral emptying rate [MD＝5.99， 95%CI （2.78， 9.21）] in trial group were increased significantly， while the level of somatostatin was decreased significantly [SMD＝－1.30， 95%CI （－1.57， －1.02）] （P≤0.000 3）. CONCLUSIONS Jianwei xiaoshi oral liquid， whether used alone or in combination with other medications， and regardless of the treatment course or dosage and usage， is effective in treating FD in children， with good safety.

Objective: To explore identification and resistance characteristics of CAMP-negativeStreptococcus agalactiae. Methods : Using matrix-assisted laser desorption ionization time-of-flight mass spectrometry(MALDI-TOF MS) and the CAMP assay, 33 presumptive strains ofStreptococcus agalactiaewere identified. The CAMP-negative strains were further validated through 16S rDNA, while the CAMP factor encoding gene(cfb) was detected using real-time fluorescence quantitative polymerase chain reaction(qPCR). Antimicrobial susceptibility testing was conducted using the microbroth dilution method, and the resistance rates of CAMP-negative and CAMP-positive strains were compared. Results : Based on MALDI-TOF MS identification, all 33 strains were classified asStreptococcus agalactiae. Among them, 7 strains tested negative for CAMP were subsequently confirmed asStreptococcus agalactiaethrough 16S rDNA. The qPCR results indicated that, only 1 strain showedcfbpresence. The CAMP-negative and CAMP-positive strains were sensitive to penicillin G, cefepime, cefotaxime, vancomycin, and linezolid. The resistance rates of the former to chloramphenicol and tetracycline(28.57%, 85.71%) were slightly higher than the latter(15.38%, 57.69%), while the resistance rates to moxifloxacin, levofloxacin, and erythromycin(14.29%, 14.29%, 42.86%) were slightly lower than the latter(34.62%, 34.62%, 57.69%), but was not significant. Conclusion Drug risistance of CAMP-negativeStreptococcus agalactiaeis the same as CAMP-positive strains, but traditional CAMP assay andcfb-targeted qPCR can result in missed detections. MALDI-TOF MS offers a quick, simple, and accurate identification method that merits wider adoption.

Objective : To explore the molecular characteristics of four CAMP negativeStreptococcus agalactiae(S.agalactiae) in whole genome sequencing. Methods : The identification of suspicious bacterial strains was conducted using matrix-assisted laser desorption ionization time-of-flight mass spectrometry(MALDI-TOF MS). For the strains confirmed asS.agalactiaethrough identification, further CAMP experiments were conducted. For CAMP negative strains, whole genome sequencing was performed using MGI DNBSEQ-T7 and MinION Flow Cell sequencing platforms. Subsequently, multi-locus sequence typing(MLST), virulence genes and resistance genes of the strains were compared and analyzed using various databases. Phoenix M50 fully automatic drug sensitivity analyzer was employed to determine the sensitivity of the bacterial strains to commonly used antibiotics. Results: Four CAMP-negativeS.agalactiaestrains were included. Whole-genome sequencing analysis revealed that all four CAMP-negativeS.agalactiaestrains belonged to the ST862 type. These strains harbored 22 virulence genes associated with capsular polysaccharides, β-hemolysin, and hyaluronidase, as well as seven resistance genes linked to macrolides, lincosamides, polypeptides, and aminoglycosides. Antimicrobial susceptibility testing revealed that CAMP-negativeS.agalactiaewas susceptible to penicillin G, cefepime, cefotaxime, and vancomycin. However, three strains exhibited resistance to erythromycin, and one strain demonstrated resistance to clindamycin. Conclusion Four CAMP negativeS.agalactiaeof the ST862 type possess multiple virulence and drug resistance genes, showing high resistance to erythromycin, warranting clinical attention.

Objective To explore the microbiological characteristics of Staphylococcus aureus(S.aureus)with no-vel incomplete hemolytic phenotype(SIHP).Methods Hemolytic phenotypes were detected and categorized by u-sing the three-point inoculation method.A total of 11 novel SIHP and 33 randomly matched S.aureus with com-plete hemolytic phenotype(SCHP)were included.Antibiotic susceptibility test was performed using broth microdi-lution method.Coagulase test was performed with freeze-dried rabbit plasma.Catalase activity was detected by slide catalase test.Expression of hemolysin genes was detected by qRT-PCR.Toxicity to human red blood cells was as-sessed by microplate method.Microplate biofilm formation was measured using crystal violet staining method.Growth kinetic determination was performed through microcultivation assay.Results Compared with SCHP,the expression profiles of the four hemolysin genes(hla,hlb,hlc,and hld)in the new SIHP were different.The new SIHP had higher resistance rates to penicillin,oxacillin,gentamicin,quinolones,clindamycin,and trimethoprim-sulfamethoxazole.Furthermore,the new SIHP had stronger hemolytic toxicity,plasma coagulase activity,and bio-film formation ability.Additionally,the new SIHP grown faster in the logarithmic phase.Conclusion Taken to-gether,the microbiological characteristics of the new SIHP are different from those of SCHP,including stronger an-tibiotic resistance and pathogenicity,which should be paid more attention by clinicians.

Objective:To investigate the clinical features of direct and indirect carotid cavernous fistulas (CCFs).Methods:Patients with CCF treated in the Affiliated Hospital of Xuzhou Medical University from January 2010 to August 2020 were enrolled retrospectively. Relevant clinical data were collected, including the main clinical manifestations, neuroimaging features, and treatment methods. The clinical features of direct and indirect CCFs were compared.Results:A total of 31 patients were enrolled in the study, 29 (93.5%) had ocular symptoms, of which conjunctival hyperemia and edema ( n=24, 77.4%), exophthalmos ( n=19, 61.3%) and orbital murmur ( n=18, 58.1%) were most common. There were 23 patients (74.2%) in direct CCF group and 8 (25.8%) in indirect CCF group. The former had more history of head trauma (78.2% vs. 12.5%; P=0.002), more flow volume (high-flow CCFs: 100% vs. 37.5%; P<0.001) and more likely to cause orbital murmur (69.6% vs. 25.0%; P=0.043). Endovascular embolization was safe and effective. The common methods of endovascular embolization were EVAL glue combined with coil embolization ( n=18, 66.7%) and detachable balloon embolization alone ( n=6, 22.2%). Conclusion:Ocular manifestations are most prominent in patients with CCFs. Direct CCF is more common, usually with a history of head trauma, and the clinical and imaging features are more typical. Interventional embolization is the preferred treatment option for patients with CCF.

OBJECTIVE： To study the anti-gout effect of aqueous extract from the stems and leaves of Erythropalum scandens （ASLE）. METHODS： The mice were randomly divided into normal group， model group， allopurinol group （positive control， 5 mg/kg）， ASLE low-dose， medium-dose and high-dose groups （1 300， 2 600， 5 200 mg/kg， by raw material； similarity hereinafter）， with 10 mice in each group. Except for normal group， other groups were given potassium oxonate intragastrically to induce hyperuricemia model. One hour after modeling， normal group and model group were given constant volume of normal saline intragastrically； administration group was given relevant medicine intragastrically， once a day， for consecutive 7 d. One hour after last administration， the levels of serum uric acid （SUA） and serum creatinine （Scr） were detected by colorimetry assay. Another mice were randomly divided into normal group， model group， indomethacin group （positive control， 7.5 mg/kg）， ASLE low-dose， medium-dose and high-dose groups， with 10 mice in each group. Normal group and model group were given constant volume of normal saline intragastrically； administration group was given relevant medicine intragastrically， once a day， for consecutive 7 d. After last administration， except for normal group， the mice were given sodium microcrystalline urate via toes to induce gouty arthritis model. Before and 1， 2， 4， 6， 8 h after modeling， the circumference of the same part of the inflamed limbs and toes of mice in each group was measured by wire binding method， and the degree of toe swelling was calculated. The number of white blood cell （WBC）， neutrophil （NEU） and lymphocyte （LYM） were detected by animal hematology analyzer. The levels of SUA and Scr were measured by colorimetry assay. The content of NO in toe tissue was determined by Griess method. RESULTS： The experimental results of hyperuricemia model showed that the levels of SUA and Scr in mice were significantly higher in model group than those in normal group （P＜0.01）. Compared with model group， above indexes of mice were decreased significantly in administration group （P＜0.05 or P＜0.01）. The experimental results of gouty arthritis model showed that the level of SUA， the degree of toe swelling （2-8 h）， the number of WBC， NEU and LYM， NO content in model group were increased significantly， compared with normal group （P＜0.05 or P＜0.01）. Compared with model group， the levels of SUA and Scr （ASLE groups）， the degree of toe swelling [indomethacin group， ASLE high-dose group （2-8 h）， ASLE low-dose group （2， 6 h）， ASLE medium-dose group （6 h）]， the number of WBC and NEU （administration groups）， the number of LYM （indomethacin group） and NO content （administration groups except for ASLE low-dose group） were decreased significantly in administration groups （P＜0.05 or P＜0.01）. CONCLUSIONS： The anti-gout effect of ASLE may be associated with promoting uric acid metabolism， anti-inflammatory and improving renal function.
