Small intestinal bacterial overgrowth(SIBO)is a clinically common but poorly recognized disease with clinical symptoms that overlap with those of functional gastrointestinal disorders(FGID). FGID is a common risk factor for the occurrence of SIBO,and its SIBO incidence rate is significantly higher than that of healthy people,and has a certain correlation. Intestinal microbiota dysbiosis(including SIBO)plays an important role in the pathophysiology of FGID. At present,the diagnosis and treatment of SIBO still face challenges,and the treatment plan of FGID is gradually introduced into the treatment of SIBO. SIBO and FGID are closely related in clinical manifestations,incidence rate,pathophysiology,treatment and other aspects,but there is little research on the relationship between them. Prospective and large-scale clinical research is still needed to improve understanding and diagnostic accuracy.This article reviews the research progress on the relationship between SIBO and FGID.

Objective:To study the role of ML-SA5, an agonist of the lysosomal Ca 2+ channel transient receptor potential mucolipin 1 (TRPML1), in promoting lysosomal exocytosis to facilitate intracellular uranium removal and alleviate uranium-induced cellular damage for human renal proximal tubule epithelial cells (HK-2) exposed to uranyl acetate. Methods:HK-2 cells were divided into the following groups to be exposed to uranyl acetate at either 0 or 300 μmol/L for 24 h, followed by treatment with ML-SA5 and/or the lysosomal exocytosis inhibitor vacuolin-1 for 0.5 h: control group (Ctrl group), ML-SA5 group (M group), vacuolin-1 group (V group), ML-SA5 plus vacuolin-1 group (M+ V group), uranium exposure group (U group), uranium exposure plus ML-SA5 group (U+ M group), uranium exposure plus vacuolin-1 group (U+ V group), and uranium exposure plus ML-SA5 plus vacuolin-1 group (U+ M+ V group). We localized lysosome-associated membrane protein-1 (LAMP-1) on the plasma membrane (surface LAMP-1) by immunofluorescence assay; measured intracellular uranium content by inductively coupled plasma mass spectrometry; measured the level of kidney injury molecule-1 (KIM-1) by immunofluorescence assay; measured the rate of cell death with Calcein-AM/PI double staining; determined the subcellular localization of transcription factor EB (TFEB) and the levels of LAMP-1 and TRPML1 proteins by immunofluorescence assay; and measured the number of lysosomes using LysoTracker probes.Results:Compared with the Ctrl group, the U group showed significant increases in the surface LAMP-1 protein level ( t = 12.86, P < 0.05), KIM-1 protein level ( t = 18.86, P < 0.05), cell death rate ( t = 38.53, P < 0.05), TFEB nuclear translocation ( t = 9.12, P < 0.05), the protein expression levels of TFEB’s downstream target genes LAMP-1 ( t = 16.47, P < 0.05) and TRPML1 ( t = 32.33, P < 0.05), and the number of lysosomes labeled with LysoTracker probes ( t = 7.75, P < 0.05). Compared with the U group, the U+ M group showed a significantly increased surface LAMP-1 level ( t = 3.33, P < 0.05) and significant decreases in the intracellular uranium level ( t = 5.01, P < 0.05), KIM-1 protein expression level ( t = 3.81, P < 0.05), and cell death rate ( t = 3.24, P < 0.05); all these effects in the U+ M group could be neutralized by the lysosomal exocytosis inhibitor vacuolin-1; and in addition, ML-SA5 significantly increased TFEB nuclear translocation ( t = 9.20, P < 0.05), the protein expression levels of LAMP-1 ( t = 3.05, P < 0.05) and TRPML1 ( t = 3.17, P < 0.05), and the number of lysosomes labeled with LysoTracker probes ( t = 3.13, P < 0.05). Conclusions:The TRPML1 agonist ML-SA5 can promote lysosomal exocytosis to enhance intracellular uranium clearance and reduce uranium-induced cellular damage/death in uranium-loaded HK-2 cells, through activating TFEB to up-regulate lysosome biogenesis and TRPML1 protein expression.

Objective:To investigate the related risk factors of surgical appendectomy after endoscopic retrograde appendicitis therapy (ERAT) in children.Methods:From September 2019 to November 2023 at the Children's Hospital Affiliated to Shandong University,the data from all related children with appendectomy after ERAT were analyzed. The general situation and main clinical manifestations of the children were collected. According to the effect of ERAT,the patients were divided into transfer to surgical group and appendicitis recurrence group by the reasons and time of transfer to surgical treatment. The indexes such as ERAT and reoperation process and pathological types of appendix after operation were collected,and the clinical experience was summarized.Results:Among the 242 children who underwent ERAT,32 cases underwent appendectomy again,including 19 males and 13 females,with an average age of(9.16±2.77)years,and the reoperation rate was 13.2%. The clinical manifestation was abdominal pain (32 cases,100.0%),mainly right lower abdominal pain (28 cases,87.5%),and the main duration was less than 3 months (30 cases,93.8%). Abdominal ultrasound or CT before ERAT mainly indicated appendicitis (11 cases,34.4%) and appendicitis complicated with appendiceal calculus (11 cases,34.4%). There were 9 children in transferred to surgical group,of which 5 cases were transferred to surgery because of ERAT intubation failure,and 4 cases were transferred to surgery because of appendix perforation or abscess. Postoperative pathology showed acute suppurative appendicitis in 5 cases and acute gangrenous appendicitis in 4 cases. There were 23 children in appendicitis recurrence group,whose abdominal pain was relieved after ERAT,but their symptoms were repeated after discharge. After clinical evaluation,they were diagnosed as recurrent appendicitis and underwent surgical appendectomy. Most of them were reoperated within 6 months after ERAT (21 cases,91.3%).Postoperative pathology was mainly chronic appendicitis (10 cases,43.5%).Conclusion:Acute suppurative appendicitis and acute gangrenous appendicitis are prone to catheterization or endoscopic failure during ERAT,and there is a high risk of surgical transfer. ERAT may relieve the symptoms of chronic appendicitis in children. If the symptoms are repeated,surgery is still needed to remove the appendix.

Objective:To explore the characteristics of natural foci of hemorrhagic fever with renal syndrome (HFRS) in Gansu Province.Methods:The information of HFRS case data and rodent density monitoring data from 2012 to 2022 in Gansu Province were collected and epidemiological methods were used to analyze and investigate the characteristics of the epidemic focus.Results:A total of 869 cases of HFRS were reported, and four patients died from 2012 to 2022. The annual incidence rate is between 0.05 per 100 000 and 1.21 per 100 000. The cases were mainly distributed in the eastern, southeast, southern, and south of the central region of Gansu Province. Most cases were distributed between age 20-60, and the sex ratio was 1.85∶1 (564∶305). Most cases were farmers (61.80%, 537/869), herdsmen (19.79%,172/869) and students (6.33%, 55/869). In a wild rat-type epidemic focus,the incidence peak was from November to January of the following year. The natural rodent hosts of HFRS were Rattus norvegicus, Apodemus agrarius, and Mus musculus. The hantaan virus carriage rates were 2.79% (21/754), 0.42% (5/1 179) and 0.31% (2/643),respectively. Three epidemic foci were defined: two derived from the Pingliang and Gannan prefecture new outbreaks epidemic foci, respectively, while the other was the residue of the Dingxi epidemic focus. Conclusions:The southern, south of the central region and eastern part of Gansu Province are current key HFRS epidemic foci dominated by Rattus norvegicus, Apodemus agrarius, and Mus musculus, respectively. The virus genotype is hantaan virus. Case reporting areas should strengthen epidemic monitoring; the key epidemic areas should strengthen and implement various prevention and control measures to reduce the harm caused by HFRS.

Objectives The combined use of bedaquiline and delamanid(BDQ-DLM)is limited by an increased risk of prolonging the QTc interval.We retrospectively evaluated patients who received DLM/BDQ-containing regimens at a TB-specialized hospital.We aimed to present clinical efficacy and safety data for Chinese patients. Methods This case-control study included patients with multidrug-resistant tuberculosis(MDR-TB)treated with BDQ alone or BDQ plus DLM. Results A total of 96 patients were included in this analysis:64 in the BDQ group and 32 in the BDQ+DLM group.Among the 96 patients with positive sputum culture at the initiation of BDQ alone or BDQ combined with DLM,46 patients(71.9%)in the BDQ group and 29(90.6%)in the BDQ-DLM group achieved sputum culture conversion during treatment.The rate of sputum culture conversion did not differ between the two groups.The time to sputum culture conversion was significantly shorter in the BDQ-DLM group than in the BDQ group.The most frequent adverse event was QTc interval prolongation;however,the frequency of adverse events did not differ between the groups. Conclusion In conclusion,our results demonstrate that the combined use of BDQ and DLM is efficacious and tolerable in Chinese patients infected with MDR-TB.Patients in the BDQ-DLM group achieved sputum culture conversion sooner than those in the BDQ group.

OBJECTIVE:
To explore the genetic basis for a patient with Dilated cardiomyopathy.
METHODS:
A patient admitted to Beijing Anzhen Hospital Affiliated to Capital Medical University in April 2022 was selected as the study subject. Clinical data and family history of the patient was collected. Targeted exome sequencing was carried out. Candidate variant was verified by Sanger sequencing and bioinformatic analysis based on guidelines of the American College of Medical Genetics and Genomics (ACMG).
RESULTS:
DNA sequencing revealed that the patient has harbored a heterozygous c.5044dupG frameshift variant of the FLNC gene. Based on the ACMG guidelines, the variant was predicted to be likely pathogenic (PVS1+PM2_Supporting+PP4).
CONCLUSION
The heterozygous c.5044dupG variant of the FLNC gene probably underlay the pathogenesis in this patient, which has provided a basis for the genetic counseling for his family.
