ABSTRACT

Objective: To compare the differences in clinical symptoms and the time required for diagnosis of benign paroxysmal positional vertigo (BPPV) between older patients and young and middle-aged patients in the structured inquiry of dizziness history. Methods: The medical records of 6 807 patients diagnosed with BPPV from the Vertigo Database of Vertigo Clinical Diagnosis, Treatment, and Research Center of Beijing Tiantan Hospital, Capital Medical University, between January 2019 and October 2021 were retrospectively analyzed. The data included basic demographic information, clinical symptoms in a structured medical history questionnaire, and the time interval from the appearance of BPPV symptoms to diagnosis consultation. The patients were divided into the young and middle-aged group (<65 years old) and the older group (≥65 years old). The differences in clinical symptoms and consultation time were compared between these two groups. Categorical variables were represented by numbers (%), and compared using Chi-squared tests or Fisher's exact probability test for analysis; whereas, continuous variables conforming to normal distribution were represented by mean±standard deviation. Both data groups were compared and analyzed by Student's t-test. Results: The mean age of the older group was 65-92 (71±5) years, while the mean age of the middle-aged group was 18-64 (49±12) years. The incidence of vertigo (42.5% vs. 49.1%, χ2=23.69, P<0.001); vertigo triggered by changes in position of the head or body (52.4% vs. 58.7%, χ2=22.31, P<0.001); and autonomic symptoms (10.1% vs. 12.4%, χ2=7.09, P=0.008) were lower, but hearing loss (11.8% vs. 7.8%, χ2=27.36, P<0.001) and sleep disorders (18.5% vs. 15.2%, χ2=11.13, P=0.001) were higher in the older group than in the young and middle-aged group. The time from the appearance of dizziness to diagnosis was commonly longer in the older patient group than the other group (55.0% vs. 38.5%, χ2=55.95, P<0.001). Conclusions: Older patients with BPPV have more atypical symptoms and complex concomitant symptoms than young and middle-aged patients. For older patients with dizziness, positional testing is needed to confirm the possibility of BPPV even if the clinical symptoms are atypical.

ABSTRACT

ObjectiveTo explore the effect of Chaishao Liujuntang on Hedgehog signaling pathway in rats with chronic atrophic gastritis (CAG) of liver depression and spleen deficiency. MethodWistar rats were randomized into normal group and modeling group. CAG with the liver depression and spleen deficiency syndrome was induced in rats in the modeling group with a compound method. After modeling, they were classified into the model group, vitacoenzyme group, Chaishao Liujuntang group, GDC-0449 (blocker) group, and Chaishao Liujuntang + GDC-0449 group. Normal group and model group were given (ig) normal saline. Vitacoenzyme and Chaishao Liujuntang group received (ig) corresponding drugs at 240 mg·kg-1·d-1 and 5.1 g·kg-1·d-1, respectively, and GDC-0449 group was treated (ip) with GDC-0449 at 50 mg·kg-1·d-1. For the Chaishao Liujuntang + GDC-0449 group, rats received GDC-0449 (ip) at 50 mg·kg-1·d-1 and Chaishao Liujuntang (ig) at 5.1 g·kg-1·d-1. The administration lasted 4 weeks. The pathological morphology of rat gastric mucosa was observed based on hematoxylin-eosin (HE) staining. mRNA and protein expression of sonic hedgehog (Shh), 12th transmembrane receptor Patched1 (Ptch1), and glioma-associated oncogene homolog 1 (Gli1) in gastric mucosa tissues was detected by real-time fluorescent quantitative polymerase chain reaction (Real-time PCR) and Western blot. Content of serum interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) was determined by enzyme-linked immunosorbent assay (ELISA). ResultCompared with normal group, the model group demonstrated decrease in gland cells, glandular atrophy, large lumen volume, plasma cell infiltration, intestinal metaplasia, decrease in the mRNA and protein expression of Shh, Ptch1, and Gli1 in gastric mucosa (P<0.01), and rise of serum IL-1β and TNF-α content (P<0.01). Compared with model group, vitacoenzyme group and Chaishao Liujuntang group showed ordered cells, alleviation of gland atrophy, and no obvious inflammatory infiltration, and GDC-0499 group and Chaishao Liujuntang + GDC-0449 showed no significant improvement. Significant rise in the mRNA and protein expression of Shh, Ptch1, and Gli1 in gastric mucosa tissues of vitacoenzyme group and Chaishao Liujuntang group (P<0.01), no significant difference in serum IL-1β content and significant decrease in TNF-α content in vitacoenzyme group (P<0.01), significant reduction in content of serum IL-1β and TNF-α in Chaishao Liujuntang group (P<0.05, P<0.01) were observed compared with those in the model group. The mRNA and protein expression of Shh, Ptch1, and Gli1 in gastric mucosa and the content of serum IL-1β and TNF-α were insignificantly different between the GDC-0449 group and Chaishao Liujuntang + GDC-0449 group. ConclusionChaishao Liujuntang can effectively improve the pathological state of gastric mucosa in CAG rats with liver depression and spleen deficiency, which may be related to the activation of Hedgehog signaling pathway and the decrease of IL-1β and TNF-α content.

ABSTRACT

This study is to prepare the pantoprazole sodium enteric-coated tablet which is compacted by pellets. The enteric-coated pantoprazole sodium pellets were prepared by fluid bed coating technology. The pantoprazole sodium enteric-coated tablets were prepared by direct compression of the enteric-coated pellets and suitable excipients. In vitro dissolution method and scanning electron microscope method were used for the observation of the drug release behavior before and after compression of the pellets. The optimized formulation is: the coating level is 55%, the plasticizer content is 20%, the ratio of Eudragit L30D-55/NE30D is 8 : 2, enteric-coated pellets/excipients (MCC/PPVP/PEG 6000 = 2 : 1 : 1) is 5 : 5, the enteric-coated tablets release in artificial gastric fluid in 2 h is less than 10%, while in artificial intestinal fluid in 1 h is more than 85%. The release behavior of pantoprazole sodium enteric-coated pellets-type tablet is quite well. And it may be used in industrial production.
