Objective:To investigate the region-specific characteristics of the gut microbiota and evaluate the association of speci?c gut microbes with type 2 diabetes mellitus (T2DM) from the Dongxiang Group in Gansu province, Northwest China.Methods:Fifty-three participants who was born in Dongxiang Autonomous County (Gansu Province) from April 2020 to January 2021 were enrolled, including 25 patients with T2DM recruited from the outpatient departments of internal medicine at The People′s Hospital of Dongxiang County(T2DM group) and 28 healthy controls recruited from the health screening center (HC group). Gut microbiome composition was analyzed using a 16S ribosomal RNA gene-based sequencing protocol.Results:A total of 936 operational taxonomic units (OTU) were obtained in the two groups. Of note, the HC and T2DM groups had 633 OTU in common. The alpha and beta diversity were different between the two groups ( P<0.05). Shannon index was significantly higher than that in the HC group, and Simpson index was significantly lower than that in the HC group, displacement multivariate analysis of variance was used to compare β diversity between the two groups, and the difference was statistically significant ( P<0.05). At the Phylum level, firmicutes and actinomycetes in T2DM group were significantly higher than those in the HC group (37.97% vs. 22.89%, 5.09% vs. 2.08%), and the differences were statistically significant ( P<0.05). The abundance of Bacteroidetes was significantly decreased (68.00% in T2DM group and 49.75% in HC group), and the difference was statistically significant ( P<0.05). At the genus level, there were 20 genera statistically significant differences between the two groups. The abundance of Bifidobacterium, Escherichia, Shigella, and Tyzzerella_4 levels were significantly increased in the T2DM group, but Prevotella_9, Erysipelotrichaceae_UCG-003, and Roseburia levels were significantly decreased in the T2DM group compared to those in the HC group.

So as to preliminary exploration the intestinal flora characteristics of T2DM in the Dongxiang group.The findings of this study provide a theoretical basis for the prevention and control of T2DM in Dongxiang group in the future.

Objective To investigate the clinical efficacy of our self-designed sight used to guide thoracic vertebroplasty.Methods A retrospective analysis was conducted of the 52 patients (70 thoracic vertebrae) who had undergone percutaneous vertebroplasty (PVP) (n =36)or percataneous kyphoplasty (PKP) (n =34) of T1-T4 vertebral bodies at Department of Orthopaedics,The First Affiliated Hospital to Zhengzhou University form August 2012 to October 2013.The operation time,intraoperative bleeding,intraoperative radiation by C-arm roentgenography,and visual analogue scale (VAS) were compared between the patients whose surgery had been guided by our self-designed sight and those whose surgery had been not.Results All the patients were followed up for 18 to 36 months (average,22.3 months).Compared with those who had not used the sight,the patients who had used the sight incurred significantly shorter operation time (16.5 ± 3.2 min versus 26.5 ± 3.7 min),significantly less intraoperative bleeding (2.8 ± 1.3 mL versus 6.3 ± 1.7 mL) and significantly less radiation by C-arm roentgenography (5.6 ± 3.3 times versus 9.4 ± 3.1 times) (P ＜0.05).The VAS scores at postoperative 3 days and final follow-up were significantly decreased than the preoperative values in all the patients (P ＜ 0.05).There were no significant differences between the patients who had used the sight and those who had not in the the VAS scores at postoperative 3 days or final follow-up (P ＞ 0.05).Conclusions The upper thoracic PVP or PKP guided by our self-designed sight has theadvantages of short operation time,less intraoperative bleeding and less frequency of C-arm radiation.The sight is suitable for various vertebroplasties.

Objective: To describe the general and histological features of the full-length superficial fascia of the circumferential upper limb. Methods: Fresh frozen arm specimens were dissected, and then MRI imaging in vivo, enhanced CT angiography and HE histological staining were used to describe the characteristics of the full-length superficial fascia of the circumferential arm and its relationship with important blood vessels. Results: The four typical structures of the superficial fascia of the arm were divided into subcutaneous superficial fat, membrane-like substance, deep fat and deep fascia from superficial to deep. The thickness and stratification, fusion degree and histological characteristics of the superficial fascia of these four layers were obviously different in different levels and regions of the arm. MRI confirmed that the total thickness of superficial fascia gradually decreased from shoulder to wrist. Venography showed that the cephalic vein ran below the second layer of superficial fascia and above the deep fascia. The basilic vein originated from the dorsal vein network of the hand and always lied below the second layer of membranous material until the basilic vein penetrates below the deep fascia of the upper arm. Conclusions The deep understanding of the circumferential full-length of superficial fascia structure of the upper limb provides an important theoretical basis for improving the surgical safety and fine operation for the Dynamic Arm Circumferential Liposuction.
