ABSTRACT

@#Objective To investigate the relationship between gait spatiotemporal parameters and balance function in stroke hemiplegic patients. Methods From September, 2018 to March, 2020, 76 stroke hemiplegic patients (38 in Brunnstrom Ⅳ and V, respectively) were assessed balance function with Active Balancer EAB-100 and Star Excursion Balance Test (SEBT), and gait parameters of speed, cadence and asymmetry, named step length asymmetry ratio (SLA), swing time asymmetry ratio (SWTA), stance time asymmetry ratio (STA), maximum flexion angle ratio (MFA) of hip and knee. The correlation among gait parameters and balance function was analysed. Results The balance and gait parameters were better in those in Brunnstrom V than in Brunnstrom Ⅳ (|t| > 2.268, P < 0.05). The speed and cadence correlated with the most balance indexes (|r| > 0.335, P < 0.05). SLA correlated with SEBT in Brunnstrom Ⅳ patients (r = -0.467~-0.613, P < 0.01), while it correlated with medial-lateral (M-L) stability limits in Brunnstrom V patients (r = -0.356, P = 0.028). SWTA correlated with stability limit of Anterior-Posterior (A-P) (r = -0.335, P = 0.040) and M-L (r = 0.510, P = 0.001), and most of SEBT (r = -0.330~ -0.445, P < 0.05) in Brunnstrom Ⅳ patients. MFA of hip and knee correlated with balance indexes in Brunnstrom Ⅳ patients (|r| > 0.326, P < 0.05), while MFA of knee correlated with most balance indexes in Brunnstrom V patients (r > 0.329, P < 0.05), and MFA of hip correlated with A-P stability limit (r = 0.369, P = 0.023). Conclusion Both speed and cadence of steps can well respond to the balance function in stroke hemiplegic patients. For the asymmetry, it is related with balance in patients with poorer recovery.

ABSTRACT

BACKGROUND@#The global pandemic coronavirus disease 2019 (COVID-19) has become a major public health problem and presents an unprecedented challenge. However, no specific drugs were currently proven. This study aimed to evaluate the comparative efficacy and safety of pharmacological interventions in patients with COVID-19.@*METHODS@#Medline, Embase, the Cochrane Library, and clinicaltrials.gov were searched for randomized controlled trials (RCTs) in patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)/SARS-CoV. Random-effects network meta-analysis within the Bayesian framework was performed, followed by the Grading of Recommendations Assessment, Development, and Evaluation system assessing the quality of evidence. The primary outcome of interest includes mortality, cure, viral negative conversion, and overall adverse events (OAEs). Odds ratio (OR) with 95% confidence interval (CI) was calculated as the measure of effect size.@*RESULTS@#Sixty-six RCTs with 19,095 patients were included, involving standard of care (SOC), eight different antiviral agents, six different antibiotics, high and low dose chloroquine (CQ_HD, CQ_LD), traditional Chinese medicine (TCM), corticosteroids (COR), and other treatments. Compared with SOC, a significant reduction of mortality was observed for TCM (OR = 0.34, 95% CI: 0.20-0.56, moderate quality) and COR (OR = 0.84, 95% CI: 0.75-0.96, low quality) with improved cure rate (OR = 2.16, 95% CI: 1.60-2.91, low quality for TCM; OR = 1.17, 95% CI: 1.05-1.30, low quality for COR). However, an increased risk of mortality was found for CQ_HD vs. SOC (OR = 3.20, 95% CI: 1.18-8.73, low quality). TCM was associated with decreased risk of OAE (OR = 0.52, 95% CI: 0.38-0.70, very low quality) but CQ_HD (OR = 2.51, 95% CI: 1.20-5.24) and interferons (IFN) (OR = 2.69, 95% CI: 1.02-7.08) vs. SOC with very low quality were associated with an increased risk.@*CONCLUSIONS@#COR and TCM may reduce mortality and increase cure rate with no increased risk of OAEs compared with standard care. CQ_HD might increase the risk of mortality. CQ, IFN, and other antiviral agents could increase the risk of OAEs. The current evidence is generally uncertain with low-quality and further high-quality trials are needed.

ABSTRACT

Artemisiae Argyi Folium, the dried leaves of Artemisia argyi, has been widely used in traditional Chinese and folk medicines for a long time. Qiai is one of the top-geoherb of Artemisiae Argyi Folium. Qiai contains various bioactive constituents, such as volatile oils, phenolic acids, flavonoids and terpenoids. Phytochemical studies demonstrated that volatile compounds are the main bioactive constituents in Qiai. Try to investigate dynamic changes of volatile components of Qiai from different harvest time and explore the optimum harvest time of Qiai, in this study, the contents of total volatile oils in Qiai collected from five different harvest time were analyzed by steam distillation method. The results showed that the contents of volatile oils of Qiai were higher in the third harvest time(around the Dragon Boat Festival), which is basically consistent with the traditional harvest time. Furthermore, a sensitive method based on gas chromatography-mass spectrometry(GC-MS) was established for qualitative analysis of volatile compounds in Qiai, and a total of thirty volatile compounds were identified. Chemometrics methods including principal component analysis(PCA) and orthogonal partial least-squares discriminate analysis(OPLS-DA) were applied to explore chemical markers and dynamic changes of volatile components in Qiai from different harvest time, and the results indicated that there were obvious differences in the relative contents of volatile compounds of Qiai samples from different harvest time. Eight volatile compounds, including α-terpinene, γ-terpinene, D-camphor, trans-carveol, α-copaene, isobornylisobutyrate, humulene, and caryophyllene oxide were selected as potential chemical markers. Among the eight chemical markers, the relative contents of α-terpinene, γ-terpinene, α-copaene and caryophyllene oxide were higher in the third harvest period(around the Dragon Boat Festival), which is consistent with the contents of total volatile oils. The present study could provide the basis for investigating the optimum harvest time of Qiai, and might be useful for the quality control of this herbal medicine.

ABSTRACT

OBJECTIVES@#Hypertension is a serious complication of pregnancy-related acute kidney injury (PR-AKI). This study aimed to determine the effect of hypertension on the prognosis of PR-AKI, maternal outcomes, and fetal outcome.@*METHODS@#Patients with PR-AKI in a hospital from January 2008 to June 2018 were enrolled for this study. Patients with or without hypertension were grouped by 1꞉1 propensity matching score. The effect of hypertension on the prognosis of PR-AKI was evaluated by multivariate Cox regression before and after matching.@*RESULTS@#Of the 30 680 women who attended the Department of Obstetrics, 126 patients were diagnosed as PR-AKI, the incidence was 0.41%. The age was (29.04±2.32) years. There were 50 cases in the hypertension group, accounting for 39.68%. Using the propensity score method, 48 pairs of patients were successfully matched, and the covariates between the two groups were balanced. After matching and adjusting for relevant clinical factors, Cox regression analysis showed that risk of end-stage renal disease (ESRD) was increased in the hypertension group compared with the normal blood pressure group (HR=2.951, 95% CI 1.067 to 8.275, =0.034). The risk of risk of adverse maternal outcome was increased (HR=2.815, 95% CI 1.271 to 6.233, =0.009), and the risk of fetal adverse outcome was increased (HR=1.437, 95% CI 1.028 to 4.623, =0.021).@*CONCLUSIONS@#Hypertension is an independent risk factor for ESRD, adverse maternal outcomes, and adverse fetal outcomes in the PR-AKI patients.

ABSTRACT

OBJECTIVE@#This study aimed to determine the prevalence and related factors of deciduous caries in 3-5-year-old preschool children in Chongqing city. Results will be used to provide a basis for the establishment and adjustment of prevention and intervention of caries in preschool children.@*METHODS@#We referred to the Fourth National Oral Health Epidemiological Survey. Data included caries prevalence in preschool children, and the questionnaires were distributed to children' parents in Chongqing city. Results were inputted by Epidata 3.1 and statistically analyzed using SPSS 21.0.@*RESULTS@#A total of 1 350 preschool children were included in the study. We found that maxillary deciduous central incisor and mandibular deciduous molars were susceptible to decay. The prevalence of primary teeth caries in preschool children in Chongqing city was 51.4% (694/1 350). The mean decayed-missing-filled-teeth (dmft) index was 2.34. The caries prevalence and mean dmft between age groups were statistically significant (P0.05). Approximately 61.7% of caries cases were concentrated in a small number (36.1%) of individuals. Multivariate Logistic regression analysis showed that age, highest educational level of parents, intake frequency of sweetened beverages and carbonated drinks, toothache or similar discomfort experience over the past year, dentist visits, and parents' assessment of teeth and oral health status of children were the factors influencing the prevalence of deciduous caries (P<0.05).@*CONCLUSIONS@#More than half of the preschool children had dental caries. Majority of caries were concentrated in a small number of individuals. The age of children, highest educational level of parents, intake frequency of sweetened beverages and carbonated drinks, toothache or discomfort experience over the past year, dentist visits, and parents' assessment of teeth and oral health status of children were associated with the prevalence of deciduous caries.

ABSTRACT

Purpose To identify the significance of different expression localization of β-catenin and its correlation with clinical pathological parameters in gastric cancer (GC) . Methods The expression of β-catenin proteins in 120 gastric cancer and 50 normal gastric mucosa samples was detected by SP immunohistochemistry. Results The positive expression of β-catenin was localized to membrane with positive rate 100. 00% in normal gastric mucosa. Lack of β-catenin membrane expression and ectopic expression in cytoplasm,nuclei,or cytoplasm/nuclei were found in GC tissue and the abnormal expression rate was as high as 81. 67% (98/120) . The abnormal expression of β-catenin was significantly correlated with histological differentiation,lymphatic metastasis and TNM stage in GC (P < 0. 05) . The nuclear expression rate of β-catenin was 36. 67% (44/120) ,and the positive nuclear expression was significantly correlated with TNM stage in GC (P < 0. 05) . The 5-year overall survival rate of β-catenin nuclear positive patients was significantly lower than that of nuclear negative ones (P < 0. 05) . Conclusion β-catenin plays a significant role in gastric cancer carcinogenesis,and its different expression localization is related to the progress of GC. β-catenin is expected to be a potential target for diagnosis and treatment of GC.

ABSTRACT

OBJECTIVE@#Systemic sclerosis (SSc) is a remarkably systemic heterogeneous connective tissue disease with many organs involved. The heart is one of the major organs involved, carrying the threat of sudden cardiac death, especially in diffuse cutaneous SSc. This review summarizes the pathophysiology, types, new diagnostic approaches, and imaging and novel therapies of primary cardiac complications while underlining the effects of recently developed non-contrast cardiovascular magnetic resonance (CMR) in early diagnosis.@*DATA SOURCES@#Medline and Embase were searched for articles published up to July 2019. A combination of Medical Subject Headings (MeSH) terms and keywords pertaining to SSc ("Scleroderma, Systemic" OR "Systemic sclerosis" OR' SSc"), AND cardiology ("cardiology" OR "heart" OR "cardiac") were applied to the search strategies.@*STUDY SELECTION@#Literature was mainly printed in English and Chinese about cardiac complications in systemic sclerosis. After selected simply on the title and abstract, the articles were included for the full text. Article type was not limited.@*RESULTS@#Relevant cardiac manifestations are complex, including arrhythmias, pericardial effusion, myocardial dysfunction, and valvular diseases. Even though the symptoms of cardiac complications are well known, unfortunately, they appear to be poor prognostic factors. As systemic sclerosis with cardiac complications has a high mortality rate and patients might have a poor quality of life, it is essential to promote early diagnosis and treatment. With the advent of non-invasive imaging techniques, such as CMR, early diagnosis of cardiac complications in SSc is becoming more effective.@*CONCLUSIONS@#Cardiac complications play an essential role in SSc and carry the threat of sudden cardiac death. More basic and clinical studies are warranted to develop better management of cardiac involvement in patients with SSc.

ABSTRACT

Increasing numbers of microbiome studies have enabled the development of a greater understanding of how antagonistic and synergetic microbial interactions influence disease outcomes. Candida albicans is an opportunistic pathogen that is commonly found in human oral microflora. In a healthy oral environment, Candida albicans may potentially but sig-nificantly influence the balance between the oral bacterial ecosystem and the host, leading tooral diseases. The aim of this study is to review the correlation between Candida albicans and oral pathogens and provide a deeper understanding of the nature of oral infec-tious diseases.

ABSTRACT

Objective: To evaluate the effectivity and safety of posterior osteotomy for thoracolumbar stress fracture in ankylosing spondylitis (AS) through the gap of a pathological fracture. Methods: Between April 2012 and August 2015, 8 patients with AS combined with thoracolumbar stress fracture were treated with posterior osteotomy through the gap of a pathological fracture to correct the kyphosis. There were 7 males and 1 female, with an average age of 51 years (range, 37-74 years). The history of AS was 1-40 years (mean, 21.7 years) and disease duration of stress fracture was 2-60 months (mean, 18.5 months). The segmental lesions included T 8, 9 in 1 case, T 10, 11 in 2 cases, T 11 in 2 cases, T 12, L 1 in 1 case, L 1, 2 in 1 case, and L 2, 3 in 1 case. The nerve function before operation according to Frankel grading was grade D in 3 cases and grade E in 5 cases. The pre- and post-operative X-ray films, CT three-dimensional reconstruction, and MRI were collected to measure the global kyphosis (GK), local kyphosis (LK), angle of the fusion levels (AFL), pelvic incidence (PI), pelvic tilt (PT), and sagittal vertical axis (SVA). Visual analogue scale (VAS) score was used to assess the back pain intensity. Results: The operation time was 210-320 minutes (mean, 267 minutes), and the intraoperative blood loss was 400-2 000 mL (mean, 963 mL). Cerebrospinal fluid leakage was found in 3 patients, and the wound healed by removal of drainage tube and suturing drainage outlet after 5-7 days of operation. The wounds of the rest patients healed by first intention. Lower extremity numbness occurred in 1 case and recovered after 1 month of postoperative administration of oral mecobalamin. All the patients were followed up 20-43 months (mean, 28.4 months). No internal fixator loosening, fracture, and other complications occurred. All the fractures healed with the healing time of 3-12 months (mean, 6.8 months). At 3 months after operation, 3 cases with spinal cord injury of preoperative Frankel grade D recovered to grade E. The GK, LK, AFL, PI, PT, SVA, and VAS scores at 1 week after operation and at last follow-up were significantly improved when compared with preoperative ones ( P0.05). Conclusion: Posterior osteotomy through the gap of a pathological fracture is a safe and effective surgical procedure for kyphosis correction and relief of back pain in AS patients combined with thoracolumbar stress fracture. Successful bony fusion and good clinical outcomes can also be achieved by this surgical procedure.

ABSTRACT

The effectiveness,safety and economy of metformin on type 2 diabetes mellitus therapy are well recognized, which has been used as the first-line oral hypoglycemic agent in recent dec-ades. Apart from hypoglycemic effect, recent studies show that metformin can exert renal protection via the mechanisms of auto-phagy induction, anti-senescence, antioxidative stress, against endoplasmic reticulum stress,anti-inflammation, and anti-fibro-sis through AMPK dependent or independent pathway, which prompt its therapeutic potential in acute kidney injury and chron-ic kidney disease. The non-hypoglycemic nephroprotective effects as well as their underlying mechanisms of metformin are summarized in this review.

ABSTRACT

HIV latent reservoirs are the latent cells and tissues of HIV under the pressure of immune responses and antiviral therapy. Although HIV infection is effectively controlled by the advent of highly active antiretroviral therapy (HAART) and the viral load in the plasma is suppressed to a low level which are undetectable by most clinical measures, HAART is not able to completely eradicate the virus in the reservoirs. The viral rebound occurs when antiviral therapy is ceased. Therefore, the eradication of HIV reservoirs is a major challenge for the therapy of AIDS. In this paper, we will focus on the strategies of eradication of AIDS latent reservoirs.

ABSTRACT

Objective To investigate the effects of galectin-2, galectin-4, galectin-7, galectin-8, and galectin-9 on the apoptosis in HIV-1-infected macrophages and to provide the theoretical and application basis for elimination of HIV-1-infected cellular reservoirs. Methods Firstly, apoptosis of human monocytic cell line THP-1 cells was induced by different concentrations of galectins to determine the suitable concentration of different galetcins. Secondly, monocytes (THP-1) were stimulated to differentiate into macrophages (THP-1-Mφ) with phorbol myristate acetate (PMA), and then macrophages were prepared and infected with HIV-1. Finally, HIV-1-infected and uninfected macrophages were respectively treated with the suitable concentrations of galectin-2, galectin-4, galectin-7, galectin-8, galectin-9 and then the apoptosis in these macrophages was detected. Results The cell death rate of macrophages without treatment was 4. 39 ± 0. 74% . The cell death rates of macrophages induced by 5 μmol/L galectin-2, 5 μmol/L galectin-4, 7. 5 μmol/L galectin-7, 3 μmol/L galectin-8 and 1 μmol/L galectin-9 were 4. 78 ± 0. 41% , 7. 21 ± 1. 46% , 3. 78 ± 1. 03% , 5. 88 ± 2. 08% , 8. 10 ± 4. 13% , respectively, with no statistically significant defferences among the groups (P> 0. 05). The cell death rate of HIV-1-infected macrophages without treatment was 12. 69 ± 1. 16% , and that of HIV-1-infected macrophages induced by 5 μmol/L galectin-2, 5 μmol/L galectin-4, 7. 5 μmol/L galectin-7, 3 μmol/L galectin-8 and 1 μmol/L galectin-9 were 11. 69 ± 0. 90% , 17. 45 ± 1. 30% , 32. 01 ± 1. 30% , 15. 77 ± 1. 21% and 19. 27 ± 2. 13% , respectively. There were significant differences between the control group and galectin-7-treated group (P < 0. 001 ). Conclusions Galectin-7-induces extensive apoptosis in HIV-1-infected macrophages but not in uninfected macrophages.
