Risk Factors of Chronic Pulmonary Aspergillosis in Patients with Etiology Positive Pulmonary Tuberculosis.

Objective: Pulmonary tuberculosis (PTB) and chronic pulmonary aspergillosis (CPA) have many similarities in clinical symptoms. In patients with etiology-positive pulmonary tuberculosis (EPTB), Aspergillus infection is easily overlooked, and missed diagnosis occurs. We attempted to analyze the clinical characteristics and risk factors of EPTB combined with CPA (EPTB-CPA), and to suggest to clinicians the possibility of CPA in EPTB patients. Methods: 58 patients with EPTB-CPA diagnosed and treated in Wuhan Pulmonary Hospital from April 2021 to March 2022 were retrospectively collected as the case group. According to the age group of the case group, 174 patients with EPTB were randomly selected as the control group at a ratio of 1:3. Multivariate logistic regression analysis was utilized to analyze the risk factors. Results: Multivariate Logistic regression analysis was performed on the pulmonary cavity, chronic obstructive pulmonary disease (COPD), bronchiectasis, emphysema, lung damage, anemia, and hypoproteinemia. Among them, pulmonary cavity (P = .001), COPD (P = .006), and bronchiectasis (P = .020) were statistically significant. Conclusion: Our findings suggest that when EPTB patients present with pulmonary cavities and comorbidities such as COPD or bronchiectasis, clinicians should consider the possibility of CPA. Identifying these risk factors can help improve the accuracy of diagnosis and facilitate early detection and management of EPTB-CPA.

Protective Effect of Lactiplantibacillus plantarum 1201 Combined with Galactooligosaccharide on Carbon Tetrachloride-Induced Acute Liver Injury in Mice.

Acute liver injury (ALI) has a high mortality rate of approximately 20-40%, and it is imperative to find complementary and alternative drugs for treating ALI. A carbon tetrachloride (CCl4)-induced ALI mouse model was established to explore whether dietary intervention can alleviate ALI in mice. Intestinal flora, intestinal integrity, biomarkers of hepatic function, systemic inflammation, autophagy, and apoptosis signals were detected through a real-time PCR, hematoxylin-eosin staining, 16S rRNA gene sequencing, and so on. The results showed that Lactiplantibacillus plantarum 1201 had a strongly antioxidant ability, and galactooligosaccharide (GOS) could boost its growth. Based on these findings, the combination of L. plantarum 1201 and GOS, the synbiotic, was applied to prevent CCl4-induced ALI in mice. The current research proved that GOS promoted the intestinal colonization of L. plantarum 1201, and the synbiotic improved the antioxidant capacity of the host, regulated the intestinal flora, repaired the intestinal barrier, inhibited the activation of the MAPK/NF-κB pathway, and then inhibited the apoptosis and autophagy pathways, relieving inflammation and liver oxidation; thereby, the ALI of mice was alleviated. These results suggest that synbiotics may become a new research direction for liver-protecting drugs.

Non-cephalosporin-susceptible, glucose non-fermentative Gram-negative bacilli meningitis in post-neurosurgical adults: clinical characteristics and therapeutic outcome.

OBJECTIVE: The clinical and laboratory characteristics of non-cephalosporin-susceptible (non-CS) glucose non-fermentative Gram-negative (G(-)) infections in adults with postneurosurgical meningitis are rarely examined solely in the literature. METHODS: The data of 28 post-neurosurgical adults meningitis with glucose non-fermentative G(-) infections, collected during a study period of 5 years (2006-2010), were reviewed. The clinical and laboratory data between the non-cephalosporin-susceptible groups and the cephalosporin-susceptible groups were compared. RESULTS: A total of 30 G(-) strains were collected from the 28 enrolled cases. Among the implicated glucose non-fermentative G(-) strains, 18 strains, belonging to 17 cases, were non-CS. Among the 18 non-cephalosporin-susceptible strains, Acinetobacter spp. (39%, 7/18) was the most common, followed by Pseudomonas spp. (22%, 4/18), Stenotrophomonas maltophilia (22%, 4/18) and Elizabethkingia meningoseptica (11%, 2/18). With a comparative analysis, there were no significant difference between the non-cephalosporin-susceptible and cephalosporin-susceptible glucose non-fermentative G(-) groups. The clinical and laboratory data were also of no statistical significance between the fatal (n=4) and non-fatal (n=13) non-cephalosporin-susceptible groups. CONCLUSION: Sixty percent (18/30) of implicated glucose non-fermentative G(-) strains of post-NS meningitis in adults are non-cephalosporin-susceptible. Among the non-cephalosporin-susceptible glucose non-fermentative G(-) strains, Acinetobacter spp., Pseudomonas spp., S. maltophilia and E. meningoseptica are the commonly implicated pathogens, and their emergence in this specific group of meningitis has caused a therapeutic dilemma. The clinical manifestations of non-cephalosporin-susceptible glucose non-fermentative G(-) meningitis were not unique; therefore, only bacterial culture and antimicrobial susceptibility test are the methods for identification confirmation.

[Therapeutic effect of double fill nine tastes soup in treating recurrent respiratory infection (RRI) and change of immune function in children].

OBJECTIVE: To investigate the therapeutic effect of double fill nine tastes soup in treating children recurrent respiratory infection (RRTI) and the change of immune function. METHOD: 77 RRTI patients were randomly selected into observation and control groups. The observation group was treated with Chinese medicine- double fill nine tastes soup,water frying points 2 times oral. The control was treated with transfer factor oral liquid,every 10 mL,2 times daily oral. Treatment periods were both two months. IgA, IgG, IgM and IL-12, TNF-alpha, INF-gamma were detected before and after treatment to assess the clinical effects and the changes of immune factors, meanwhile, a health group was established. RESULT: Before treatment, compared with the health group, the serum IgA, IgG, IgM, IgE, IL-12, TNF-alpha, IFN-gamma in both groups were significantly different (P < 0.01). After treatment, the ratio of IgA, IgG, Ig M, IL-12, TNF-alpha, IFN-gamma in two groups were significantly different (P < 0.01). Compared with the recurrence rate and clinical effects, the observation group was better than control, and the differences were significant (P < 0.01). CONCLUSION: Double fill nine tastes soup has significant effects in treating recurrent respiratory infection (RRI) and enhance the immune function in children.
