Objective: To study genotype distribution and the characteristics of hepatitis B virus (HBV) in Uighur patients with chronic hepatitis B (CHB) in Xinjiang, China.
Methods: Type specific primers and PCR were used to detect the HBV genotypes of 127 Uighur CHB patients in Xinjiang. Genotyping results were confirmed by PCR product sequencing.
Results: Among the 127 patients, the proportions of genotype D, B, C and B/D, C/D, B/C/D were 39.4% (50/127), 22.0% (28/127), 16.5% (21/127) and 9.4% (12/127), 8.7% (11/127) and 3.9% (5/127), respectively. The distribution of the HBV genotypes showed no significant differences between male and female patients (x2 = 8.058, P > 0.05), between HBeAg positive and negative patients (x2 = 6.033, P > 0.05), and between patients of different ages (x2 = 3.137, P > 0.05).
Conclusion: Genotype D HBV is predominant in Uighur patients with chronic hepatitis B in Xinjiang. The distribution of various HBV genotypes shows no significant differences between these Uighur patients with different HBeAg positivity, sex and age.

Background: Early prediction of mortality in individuals with HIV (PWH) has perpetually posed a formidable challenge. With the widespread integration of machine learning into clinical practice, some researchers endeavor to formulate models predicting the mortality risk for PWH. Nevertheless, the diverse timeframes of mortality among PWH and the potential multitude of modeling variables have cast doubt on the efficacy of the current predictive model for HIV-related deaths.

Purpose: This study analyzes the relationship between human papillomavirus (HPV) infection, vaginal microecology, and cervical lesions to provide a basis for the prevention and treatment of cervical cancer (CC) in the Xinjiang region.
Methods: Real-time quantitative PCR was used for HPV genotyping and viral load. The Gram staining and dry biochemical enzyme kit were utilized to diagnose vaginal secretions.

Background: Brucellosis is a severe zoonotic disease that is often overlooked, particularly in impoverished countries. Timely identification of focal complications in brucellosis is crucial for improving treatment outcomes. However, there is currently a lack of established indicators or biomarkers for diagnosing these complications.

Background: Disuse is a typical phenotype of osteoporosis, but the underlying mechanism has yet to be identified in elderly patients. Disc collapse and intervertebral disc (IVD) fibrosis are two main pathological changes in IVD degeneration (IDD) progression, given that these changes affect load transmission patterns, which may lead to disuse osteoporosis of vertebral bodies and zygapophyseal joint (ZJ) osteoarthritis (ZJOA) biomechanically.
Methods: Clinical data from 59 patients were collected retrospectively.

Article Synopsis
- - Cervicogenic headache (CEH) is linked to issues in the upper cervical spine and can significantly lower quality of life; a new ultrasound-guided technique called the "three in one" approach aims to improve treatment outcomes by targeting specific nerve areas with one injection.
- - The study involved patients who didn’t respond to other treatments and utilized ultrasound and fluoroscopy to accurately perform nerve blocks, with follow-ups assessing pain relief through numerical rating scales at different intervals post-treatment.
- - Results showed that all patients experienced improved pain scores after using the new technique, with no complications reported, suggesting that the "Three in One" approach and interfascial plane blocks may be effective treatments for CEH.
