The prevalence of 2.5% for HLA-B27 in the general Saudi population was similar to that of Omair et al. using samples of Saudi cord blood [14]. The positivity in females was 1.5 times higher than in males. No correlation was seen between HLA-B27 and gender and blood groups.

Deoxyribonuclease 1-like 3 (DNASE1L3) is an endonuclease associated with many autoimmune diseases and tumors. However, the serum DNASE1L3 level in hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) remains unreported. Thus, this study compared the diagnostic value of DNASE1L3 and alpha-feto-protein (AFP) individually and in combination in HBV-related HCC.

The study population consisted of 88 patients with HBV-related HCC, 80 patients with HBV-related liver cirrhosis (LC) and 88 control subjects. The serum DNASE1L3 levels were measured using an enzyme-linked immunosorbent assay. The serum AFP was also assayed.

Our data showed that the serum DNASE1L3 levels were significantly higher in patients with HBV-related HCC than in the healthy controls and patients with LC. When the two biomarkers were analyzed individually, the receiver operating characteristic curve analysis showed that the areas under the curve of DNASE1L3 and AFP were 0.898 and 0.866, respectively. When DNASE1L3 and AFP were combined, the area under the curve was 0.951. The sensitivities of DNASE1L3 and AFP were 72.73% and 74.81%, respectively, and the specificities were 93.18% and 92.05%, respectively, in the diagnosis of HBV-related HCC. The sensitivity of the two combined could be improved to 89.77%. However, no correlation was found between serum DNASE1L3 and AFP in HBV-related HCC patients (r = 0.005, p = 0.734).

Serum DNASE1L3 has high sensitivity and specificity in the diagnosis of HCC. DNASE1L3 combined with AFP has higher sensitivity and can improve the diagnostic efficiency of HBV-related HCC.

To improve the quality of pre-analytical phase and provide targeted suggestions, this study analyzed factors causing unqualified clinical specimens in patients of the Department of Clinical Laboratory of Renmin Hospital of WuHan University from 2015 to 2019.

Inpatient specimens from January 2015 to December 2019 were retrospectively analyzed. Unqualified specimens were identified by referring to the general principle of rejection. The analytical indicators included incidence rate of unqualified specimens and constituent ratio of reasons of unqualified specimens. These two indicators were analyzed according to the inpatient wards and types of specimens.

From 2015 to 2019, 21,674 inpatient unqualified specimens were collected, the incidence rate of unqualified specimens was 0.22% (21,674/9,700,869), the number and rate of unqualified specimens decreased year by year. The main reasons of unqualified specimens were insufficient volume (29.67%, 6,430/21,674) and clotting (26.31%, 5,703/21,674). The number of unqualified specimens in the departments of cardiovascular, pediatrics, neurology, oncology, urinary surgery, and intensive care unit ranked the top each year. Ilomastat in vivo Clotting (39.29%, 5,682/14,462) was the main reason of unqualified blood specimens while insufficient volume (71.18%, 3,365/4,727) was for urine specimens. Wrong identification caused unqualified feces (62.65%, 728/1,162) and body fluid (40.74%, 539/1,323) specimens.

Clinical laboratory could make effective measures to improve pre-analytical quality by retrospectively analyzing data of unqualified specimens.

To explore the comprehensive treatment of group A streptococcus haemolyticus complicated with streptococcal toxic shock syndrome (STSS) in surgery.

Six patients with Type II necrotizing fasciitis complicated with STSS were enrolled from September 2018 to October 2019 in the Burn Department at Quanzhou First Hospital. The patients were treated with early incision and reduction of tension, anti-shock, anti-infection, primary debridement and vacuum suction, maintenance of organ function, and adjustment of internal environment, secondary autologous skin graft, and early rehabilitation.

Five patients were healed, while one elderly patient refused treatment.

We should be alert to necrotizing fasciitis caused by group A hemolytic streptococcus (GAS) infection and effectively avoid the occurrence of STSS. By making an incision to reduce tension, adopting the principle of anti-infection, and actively anti-shock, maintaining the function of internal organs and the stability of internal environment, debridement and vacuum suction in early and effective stage, followed by selfskin graft to seal the wound and early rehabilitation the treatment of Type II NF and STSS can be effectively improved.

MicroRNAs have been shown to play a critical role in early diagnosis of hepatocellular carcinoma. Nevertheless, microRNAs’ functions in serum of patients with hepatocellular carcinoma (HCC) are not fully understood.

qRT-PCR was used to detect the expression level of microRNA-203a (miR-203a) in clinical serum samples of HCC and HepG2 cells. Kaplan-Meier method was used to estimate overall survival, and the cell scratch test was used to observe the migration ability of cells in vitro.

Here, we first observed that serum miR-203a was significantly upregulated in HCC patients with HBV compared to without HBV. In HCC patients, miR-203a low expression was positively related with poor overall survival. In addition, we found that HBV improved the poor prognosis of HCC patients with lower miR-203a levels. After successfully constructing HepG2 cell line carrying HBV, further studies demonstrated miR-203a expression level was increased in HepG2 with HBV compared to without HBV.

Lower serum miR-203a level in HCC patients led to worse overall survival, which depended on HBV. In vitro, miR-203a level was positively correlated with HBV. Therefore, our studies provided the novel insight into the role of serum miR-203a in HCC patients with HBV and potential new molecular target for early diagnosis of hepatitis B virus-related hepatocellular carcinoma.

Severe pneumonia (SP) is a clinically critical acute disease which has a higher mortality rate among infectious diseases. In this report, a rare case of severe pneumonia with severely high lactic acid (up to 24 mmol/L) and relatively normal pH was analyzed.

The case was discussed from different angles including acid-base balance disorder, the use of extractor-poreal membrane oxygenation (ECMO), dialysis treatment, circulatory disturbance, and inspection methodology.

Hypoxia and dissolution of muscles caused by circulatory disorders may be the cause of the abnormal increase of lactate in this case; while the relatively normal pH may be caused by the dialysis treatment.

Such a high blood gas lactic acid value is extremely rare, and this increase is not due to the limitations of the test method. High lactic acid may not result in the significant decrease of pH when the patient receives continuous systemic treatment.

The circulating levels of Cyr61 (also known as CCN1) may prove to have great clinical value in the diagnosis, monitoring and prognosis of many disorders in humans. However, the reference intervals (RIs) for this analyte in human subjects have not previously been well established. Therefore, establishing RIs and determining the distribution of circulating Cyr61 levels are very important for future clinical studies and could provide an orientation value for exploring its clinical usefulness.

The Cyr61 levels in 2,514 healthy Chinese Han subjects (1,250 males and 1,264 females, aged 18 – 88 years, recruited from 4 hospitals in Shanghai and Fujian) were measured with a sandwich ELISA (R&D Systems, USA). The RIs were determined in a manner consistent with the Clinical and Laboratory Standards Institute guidelines.

The levels of serum Cyr61 showed a non-Gaussian distribution. A statistically significant difference was observed between the males and females such that the median level of Cyr61 in the males plays a role in the regulation of Cyr61 expression in vivo.

Lung adenocarcinoma (LUAD) is still a worldwide challenge. Accumulated evidence demonstrates that the superiority of immune-related long noncoding RNAs (lncRNAs) are closely connected with tumorigenesis and prognosis of cancer. However, no detailed studies have been conducted to present a reliable signature for predicting prognosis in LUAD patients from the perspective of tumor immunology. The aim of this study was to con-struct a risk score model based on the signature of the group of seven immune-related lncRNAs to predict the prognosis of patients with LUAD.

We performed a genome-wide analysis of expression profiles in 522 LUAD patients from The Cancer Genome Atlas (TCGA) project to explore the prognostic ability of immune-related lncRNAs. By using Kaplan-Meier analysis, univariate/multivariate Cox regression, receiver operating characteristic curve (ROC), and principal components analysis (PCA), a risk score model was constructed based on the signature of the group of seven immune-related lncRNAs to peatment in LUAD.

Platelet antigens can stimulate the body to produce platelet alloimmune antibodies through blood transfusion, pregnancy, and autoimmunity. In the blood of pregnant women, anti-platelet antibodies can cause embryo implantation failure, abortion, etc. if they are present.

The platelet antibody was screened in 326 infertile patients (282 primary infertility and 44 secondary infertility) and 522 healthy controls in the physical examination center of our hospital by solid phase agglutination of red blood cells.

The positive rate of anti-platelet antibody was 9.51% in the infertility group and 2.30% in the healthy control group. There was a significant difference between them (χ2 = 4.51, p < 0.05). The positive rate of anti-platelet antibody in the infertility group was significantly higher than that in the control group. The positive rate of anti-platelet antibody in the secondary infertility patients was significantly higher than that in the primary infertility patients (χ2 = 1.62, p < 0.05), and the positive rate of serum anti-platelet antibody increased gradually with the increase of infertility years.
