Objective To evaluate the efficacy and safety of Elvitegravir, Cobicistat, Emtricitabine and Tenofovir Alafenamide Fumarate Tablets in initial treatment of acquired immune deficiency syndrome (AIDS) patients. Methods A total of 80 treatment-naive AIDS patients were selected as research subjects and randomly divided into control group and observation group, with 40 patients in each group. The control group was treated with free antiviral drugs (tenofovir + lamivudine + efavirenz), while the observation group was treated with Elvitegravir, Cobicistat, Emtricitabine and Tenofovir Alafenamide Fumarate Tablets. The CD4⁺ count, human immunodeficiency virus (HIV) viral load, and biochemical indicators were compared between the two groups before treatment and at 3, 6, 9, and 12 months after treatment. The adherence, adverse reactions, and quality of life were also compared between the two groups. Results During the treatment, six patients in the observation group and 9 patients in the control group had no compliance. With the extension of treatment time, the CD4⁺ level in both groups gradually increased, and the HIV viral load gradually decreased (P < 0.05). After 3, 6, 9, and 12 months of treatment, the CD4⁺ levels in the observation group were higher than those in the control group, and the HIV viral loads were lower than those in the control group (P < 0.05). With the extension of treatment time, the levels of alanine aminotransferase, aspartate aminotransferase, urea, creatinine, and uric acid in the control group gradually increased, and the random blood glucose levels after 3, 6, 9, and 12 months of treatment in the control group were higher than those before treatment (P < 0.05). After 3, 6, 9, and 12 months of treatment, the levels of alanine aminotransferase, aspartate aminotransferase, urea, creatinine, uric acid, and random blood glucose in the observation group were lower than those in the control group (P < 0.05). The incidence of adverse reactions in the observation group was 2.94% (1/34), which was lower than 90.00% (36/40) in the control group (corrected χ²=55.718, P < 0.001). With the extension of treatment time, the scores of various dimensions of quality of life in both groups gradually increased, and the scores of various dimensions of quality of life after treatment in the observation group were higher than those in the control group (P < 0.05). Conclusion Compared with the free antiviral drug regimen, Elvitegravir, Cobicistat, Emtricitabine and Tenofovir Alafenamide Fumarate Tablets shows better efficacy in the treatment of AIDS-naive patients, which can significantly increase the CD4⁺ level, and reduce the HIV viral load. Besides, it has high safety, and can significantly improve their quality of life.

OBJECTIVE: To review the application of cell derived decellularized extracellular matrix (CDM) in tissue engineering. METHODS: The literature related to the application of CDM in tissue engineering was extensively reviewed and analyzed. RESULTS: CDM is a mixture of cells and their secretory products obtained by culturing cells in vitro for a period of time, and then the mixture is treated by decellularization. Compared with tissue derived decellularized extracellular matrix (TDM), CDM can screen and utilize pathogen-free autologous cells, effectively avoiding the possible shortcomings of TDM, such as immune response and limited sources. In addition, by selecting the cell source, controlling the culture conditions, and selecting the template scaffold, the composition, structure, and mechanical properties of the scaffold can be controlled to obtain the desired scaffold. CDM retains the components and microstructure of extracellular matrix and has excellent biological functions, so it has become the focus of tissue engineering scaffolds. CONCLUSION CDM is superior in the field of tissue engineering because of its outstanding adjustability, safety, and high bioactivity. With the continuous progress of technology, CDM stents suitable for clinical use are expected to continue to emerge.

Objective To explore the relationship between serum levels of tyrosine hydroxylase (TH) and the risk of cerebral infarction in Parkinson's patients. Methods A total of 129 patients with confirmed Parkinson's disease who were hospitalized in our hospital were selected, among the 58 patients had Parkinson's disease complicated with cerebral infarction (complicated with cerebral infarction group), and the remaining 71 patients had Parkinson's disease alone (control group). Blood TH levels and other potential related information were collected retrospectively at the time of diagnosis. Comparative analysis of data was performed using SPSS software. Results Comparing the serum TH expression levels in patients with Parkinson's disease and patients with cerebral infarction at admission , the serum TH level in patients with cerebral infarction was lower. Results also showed that the levels of CRP, IL-6, MDA, and Hcy were higher in patients with cerebral infarction, while PON-1 level was lower. In addition, patients with cerebral infarction had lower motor ability (higher UPDRS Ⅲ score). Further regression analysis was carried out with the occurrence of Parkinson's disease complicated with cerebral infarction as the dependent variable and the potential influencing factors as the independent variable. The results indicated that factors such as low expression of TH, high expression of inflammatory factors, and high expression of oxidative stress factors were positively correlated with the risk of complications of the two diseases. Conclusion The low expression of TH, inflammatory state and high oxidative stress state are the potential risk factors for Parkinson's disease complicated with cerebral infarction, which deserves clinical attention.

Objective:To explore the relationship between the neural development of preterm infants and gut microbiota.Methods:66 premature infants who were hospitalized in the Neonatology Department of Hunan Children′s Hospital from September 2018 to September 2019 were included in the study. Their fecal samples and clinical data from the first admission were collected. According to the neurodevelopment, the patients were divided into normal neurodevelopment group and neurodysplasia group. The bacterial DNA of fecal samples was extracted by 16S rDNA high-throughput sequencing technology and bioinformatics analysis was conducted to compare the composition and diversity of gut microbiota between the two groups.Results:(1) The Shannon index of gut microbiota in normal neurodevelopmental group and neurodysplastic group was 0.89(0.41, 1.51) and 1.01(0.47, 1.31), respectively. There was no significant difference in diversity index between the two groups ( P>0.05). (2) Bifidobacterium, veronica and negativites in the gut microbiota of the normal neurodevelopmental group were significantly higher (all P<0.05), and streptococcus in the gut microbiota of the dysplastic group were significantly higher ( P<0.05). The gut microbiota of the two groups were mainly enterococcus and escherichia shigella. Conclusions:At the genus level, enterococcus and escherichia are the dominant flora of early gut microbiota in preterm infants. Gut microbiota is related to the neural development of preterm infants. The increased abundance of streptococcus, and the decreased abundance of bifidobacterium, veronicus, and negativites may be risk factors for neurodysplasia of preterm infants. The diversity of gut microbiota in early preterm infants may not be significantly related to neural development.

【Objective】 To compare the clinical efficacy of unilateral biportal endoscopic （UBE） and microscopic discectomy in the treatment of lumbar disc herniation （LDH） and to explore the safety and effectiveness of this operation. 【Methods】 A total of 87 LDH patients from July 2018 to July 2021 were analyzed retrospectively， including 42 cases of unilateral biportal endoscopic discectomy and 45 cases of microscopic discectomy. Analysis was based on comparison of perioperative metrics， operation time， and estimated blood loss. Clinical outcomes were evaluated using visual analogue scale （VAS）， Oswestry disability index （ODI） and modified Macnab criterion. 【Results】 All patients were followed up for 13.3±1.18 months. In UBE group， operation time （57.12±6.35） min was shorter than that in the microscope group （62.21±7.09） min and estimated blood loss （29.31±3.62） mL was smaller than that in the microscope group （51.77±8.43） mL， with a significant difference （P<0.05）. The two groups of patients had significantly lower back pain VAS score， leg pain VAS score， and ODI index than those before operation （P<0.05）. The VAS score of lower back pain at 3 days after operation and the ODI index at 1 month after operation were significantly lower in UBE group than in the microscope group （P<0.05）. At other time points， there was no significant difference in lower back pain VAS score， leg pain VAS score or ODI index （P>0.05）. Dural sac tear occurred in 2 cases in UBE group and 3 cases in the microscope group； the incidence was not statistically significant （P>0.05）. Modified MacNab criterion evaluation at the last follow-up showed that 32 cases were excellent in UBE group， 7 cases were good， and 3 cases were fair， with the excellent and good rate of 92.9% （39/42）. The microscope group was excellent in 31 cases， good in 10 cases， and fair in 4 cases， with the excellent and good rate of 91.1% （41/45）. 【Conclusion】 UBE for LDH has a satisfactory short-term clinical efficacy， with the advantages of less trauma， greater efficiency， clear vision， and large operating space. Both UBE and microscopic discectomy can achieve good clinical results in treating LDH， but the former has the advantages of less trauma， high efficiency， and quick postoperative recovery.

Objective:To investigate the diagnostic value of integrated 18F-fluorodeoxyglucose (FDG) PET/MRI multimodal imaging in the grading of adult diffuse gliomas. Methods:A retrospective analysis was performed; 29 patients accepted cranial 18F-FDG PET/MRI multimodal imaging and diagnosed as having adult diffuse gliomas in our center from January 2020 to December 2021 were chosen; their clinical and image data were collected. These patients were divided into low-grade group (WHO grading II, n=13) and high-grade group (WHO grading III and IV, n=16) according to the pathological results confirmed by surgery or biopsy. T1WI, T2WI, DWI, arterial spin labeling (ASL), magnetic resonance spectroscopy (MRS) and PET were performed in these patients. Differences in T1WI and T2WI signs between the two groups were compared. Differences in maximum standard uptake value (SUV max), apparent diffusion coefficient (ADC), choline/ N-acetylaspartate (Cho/NAA), NAA/creatine (Cr), Cho/Cr, relative cerebral blood flow (rCBF) between the two groups were compared. The diagnostic efficacies of above parameters in differentiating high-grade from low-grade adult diffuse gliomas were determined by receiver-operating characteristic (ROC) curves. The predictive probabilities for differentiating high-grade from low-grade adult diffuse gliomas using combined parameters were obtained by binary Logistic regression analysis. Results:There were no statistical differences in T1WI and T2WI signs, proportion of adjacent parenchyma edema, proportion of crossing the midline into the contralateral side, proportion of mass effect, proportion of cystic degeneration/necrosis, or site of growth between low-grade and high-grade groups ( P>0.05). The values of SUV max, ADC, Cho/NAA, Cho/Cr and rCBF were statistically different between the two groups, and the order of diagnostic efficiency was SUV max>ADC>Cho/NAA>rCBF>Cho/Cr>NAA/Cr. SUV max had the highest diagnostic efficacy in differentiating high-grade from low-grade adult diffuse gliomas with an area under the curve (AUC) of 0.894, a sensitivity of 75% and a specificity of 100%; the diagnostic efficacy of combined parameters (mean AUC>0.9) was higher than that of single parameter, and the combined parameters of SUV max and Cho/NAA showed the highest diagnostic efficacy with an AUC of 0.933, a sensitivity of 81.3% and a specificity of 92.3%. Conclusion:The 18F-FDG PET/MRI multimodal imaging is helpful in the grading diagnosis of adult diffuse gliomas, and combination of PET and MRS may play a greater role.
