Therapeutic Effectiveness of Leukocyte- and Platelet-rich Fibrin for Diabetic Foot Ulcers: A Retrospective Study.

Objective: Diabetic foot ulcer (DFU) is one of the most serious complications of diabetes. Leukocyte- and platelet-rich fibrin (L-PRF) is a second-generation autologous platelet-rich plasma. This study aims to investigate the clinical effects of L-PRF in patients with diabetes in real clinical practice.

Nickel oral bioavailability in contaminated soils using a mouse urinary excretion bioassay: Variation with bioaccessibility.

To assess the health risk of nickel (Ni) in contaminated soils, studies rarely evaluated Ni bioavailability in the gastrointestinal (GI) tract, limiting the accurate regulation of contaminated sites. Here, for 15 soil samples contaminated by Ni-electroplating, Ni oral relative bioavailability (RBA, relative to NiSO) was measured using a mouse urinary excretion bioassay. Nickel-RBA varied from 7.

Whole-genome sequencing reveals origin and evolution of influenza A(H1N1)pdm09 viruses in Lincang, China, from 2014 to 2018.

The continuous variation of the seasonal influenza viruses, particularly A(H1N1)pdm09, persistently threatens human life and health around the world. In local areas of southwest china, the large time-scale genomic research on A(H1N1)pdm09 is still insufficient. Here, we sequenced 45 whole-genome sequences of influenza A(H1N1)pdm09 viruses in Lincang, China, from 2014 to 2018, by next-generation sequencing technology to characterize molecular mechanisms of their origin and evolution.

[Expression of TGF-beta1/Smad protein in rat liver fibrosis model and the role of IFN-gamma].

Objective: To study the impact of IFN-gamma on liver fibrosis and its possible mechanism. Thirty healthy male SD rats were randomly divided into two groups: fibrosis model group, IFN-gamma treatment group. Experimental liver fibrosis was induced by subcutaneous injection of CCl4.

Spatiotemporal transmission and determinants of typhoid and paratyphoid fever in Hongta District, Yunnan Province, China.

Background: Typhoid and paratyphoid fever are endemic in Hongta District and their prevalence, at 113 per 100,000 individuals, remains the highest in China. However, the exact sources of the disease and its main epidemiological characteristics have not yet been clearly identified.

Methods And Findings: Numbers of typhoid and paratyphoid cases per day during the period 2006 to 2010 were obtained from the Chinese Center of Disease Control (CDC).

[siRNAs targeting La, hVAP-33, eIF2Bgamma, and HCV IRES inhibit the replication and expression of HCV in Huh7 cells].

Objective: To investigate the in vivo functional roles of the La autoantigen (La), the human homologue of the 33-kDa vesicle-associated membrane protein-associated protein (hVAP-33), and the subunit gamma of the human eukaryotic initiation factors 2B (eIF2Bgamma) as co-infection factors supporting chronic infection with hepatitis C virus (HCV).

Methods: Small interfering (si)RNAs were designed against the HCV internal ribosome entry site (IRES) and transfected into Huh7 cells chronically infected with the HCV pseudovirus (designated as Huh7-HCV cells). The IRES siRNA producing the most effective silencing was selected for further analysis by fluorescence quantitative polymerase chain reaction (qPCR).

[Burden of disease regarding paratyphoid fever A - based on the Syndromic Surveillance System on Fever].

Objective: To evaluate the burden of paratyphoid fever A in Hongta district, Yuxi city, Yunnan province from May 1, 2008 to April 30, 2009 so as to provide information for the development of comprehensive intervention measures.

Methods: Based on the Fever Syndromic Surveillance System, information as attendance rate of patients with fever, rate of patients being sampled, laboratory testing rate, sensitivity on the detection of blood culture and the rate of case reporting etc. were calculated.

Effect of Yiqi Bufei recipe [see text] on patients with pulmonary incompetence after pneumonectomy.

Objective: To study the effect of Yiqi Bufei Recipe ([see text], YBR) on surgical tolerability, pulmonary compensatory function and post-operation rehabilitation in patients with pulmonary incompetence (PI) after pneumonectomy.

Methods: YBR intervention was applied to 60 patients with PI after pneumonectomy (as test group), the pulmonary and cardiac functions changes before and after operation, occurrence of postoperative complications, mortality, and the number of hospitalization days and intensive care unit (ICU) confinement period were observed. Meantime, for the negative and positive controls, the same parameters were observed comparatively in 60 patients with normal lung function, and in 60 patients with PI undergoing a similar operation but untreated with Chinese herbs.

Rule of Chinese medicine syndrome differentiation in the patients with thoracic diseases at perioperation stage.

Objective: To study the rule of syndrome differentiation in the patients with thoracic diseases at perioperation stage.

Methods: A standard was created referring to the related literature, and it was applied to differentiate the Chinese medicine syndrome in 150 patients before and three days after thoracic operation.

Results: Before operation, Chinese medicine syndromes were as differentiated as phlegm type in 45.

[Typhoid and paratyphoid fever in Yunnan province: distributional patterns and the related meteorological factors].

Objective: To characterize the spatial distribution of typhoid and paratyphoid fever (TPF) in Yunnan province, China and to determine the effectiveness of meteorological factors on the epidemics of TPF.

Methods: Data of reported TPF cases in Yunnan province (2001 - 2007) from the China Information System for Diseases Control and Prevention was applied to GIS-based spatial analyses to detect their spatial distribution and clustering of TPF incidence at the county level. Panel data analysis was used to identify the relationships between the TPF incidence and meteorological factors including monthly average temperature, monthly cumulative precipitation and monthly average relative humidity.

Financial barrier against access to diagnostic procedures among enteric fever suspects in highly-endemic areas of China.

There is currently no public financial system that fully covers enteric fever suspects in China. This study aimed at documenting the level of access to definitive diagnostic procedures, especially haemoculture, for these patients and examining the effect of health insurance on access to such care. A hospital-based cross-sectional study was conducted in six counties of Yunnan province, using a structured questionnaire and data extraction from medical records.
