BACKGROUND: Paraquat (PQ) is an effective herbicide and is widely used in agricultural production, but PQ poisoning is frequently seen in humans with the lung as the target organ. Currently, there are many studies on lung injury after PQ poisoning. But the kidney as the main excretory organ after PQ poisoning is rarely studied and the mechanisms of this poisoning is not very clear. In this study, we observed the expression of caspase-3 and livin protein in rat renal tissue after PQ poisoning as well as the therapeutic effects of ulinastatin. METHODS: Fifty-four Sprague-Dawley (SD) rats were randomly divided into three experimental groups: control group (group A), paraquat poisoning group (group B) and ulinastatin group (group C), with 18 rats in each group. Rats in group B and group C were administered intragastrically with 80 mg/kg PQ, rats in group C were injected peritoneally with 100000 U/kg ulinastatin once a day, while rats in group A were administered intragastrically with the same volume of saline as PQ. At 24, 48, 72 hours after poisoning, the expression of livin in renal tissue was detected by Westen blotting, the expression of caspase-3 was detected by immunohistochemistry, and the rate of renal cell apoptosis was tested by TUNEL detection. The histopathological changes were observed at the same time. RESULTS: Compared to group A, the expression of caspase-3 in the renal tissue of rats in groups B and C increased significantly at any time point. Compared with group B, the expression of caspase-3 in renal tissue of rats in group C decreased. Compared with group A, the expression of livin in renal tissue in rats of groups B and C increased significantly at any time point (P<0.01), especially in group C (P<0.01). TUNEL method showed that the rate of renal cell apoptosis index was higher in group B at corresponding time points than in group A (P<0.01), and was lower in group C at corresponding time points than in group B (P<0.01). CONCLUSION: UTI has a protective effect on the renal tissue of rats after paraquat poisoning through up-regulating the expression of livin and down-regulating the expression of caspase-3, but the regulation path still needs a further research.

OBJECTIVETo construct a cell model of 4.1R gene knockout in murine macrophage cell line RAW264.7 using CRISPR/Cas9 technique.

METHODSThree high?grade small?guide RNAs (sgRNAs) that could specifically identify 4.1R gene were synthesized and inserted into lentiCRISPRv2 plasmid. RAW264.7 cells were infected with sgRNA?Cas9 lentivirus from 293T cells transfected with the recombinant sgRNA?lentiCRISPRv2 plasmid, and the positive cells were screened using puromycin and the monoclonal cells were obtained. The expression of 4.1R protein in the monoclonal cells was measured by Western blotting, and the mutation site was confirmed by sequence analysis. Result A 4.1R gene knockout RAW264.7 cell line was obtained, which showed a 19?bp deletion mutation in the 4.1R gene sequence and obviously enhanced proliferation.

CONCLUSIONWe successfully constructed a 4.1R gene knockout macrophage cell line using CRISPR/Cas9 technique, which may facilitate further investigation of the function of 4.1R in macrophages.

OBJECTIVETo study the relationship between knee osteoarthritis (OA) and intercondylar notch narrowing based on the notch width index.

METHODSMagnetic resonance (MR) images were collected from middle-aged and elderly patients with a definite diagnosis of knee OA, including 42 with mild OA and 37 with moderate to severe OA, with 70 healthy individuals serving as the control group. The notch width indexes NWI, NWI-A, and NWI-P on the coronal images at different levels were calculated, and the intercondylar notch was classified, according to the features on axial MR images, into types A, U, and W. The association of OA with NWI, NWI-A, NWI-P, and notch type was determined, and the cutoff values were obtained based on the ROC curves at different levels as indicators for diagnosis of intercondylar notch stenosis.

RESULTSIn the control, mild OA, moderate to severe OA groups, the NWI value on coronal MR images were 0.252±0.019, 0.251±0.017, and 0.240±0.020, NWI-A were 0.261±0.024, 0.259±0.023, and 0.245±0.023, and NWI-P were 0.271±0.026, 0.270±0.024, and 0.254±0.022, respectively. Patients with moderate to severe OA had significantly smaller NWI, NWI-A, and NWI-P than the other two groups (P<0.05), and a significant association was found between NWI values at each level and the occurrence of moderate to severe OA (P<0.01). A NWI value<0.248, NWI-A<0.256, and NWI-P<0.266 supported a diagnosis of intercondylar notch narrowing. Type A intercondylar notch was found in the majority of patients with intercondylar notch narrowing (P<0.05).

CONCLUSIONPatients with moderate to severe OA have significant intercondylar notch narrowing, and patients with a type A intercondylar notch are more likely to have intercondylar notch narrowing than those with type U notch.

BACKGROUNDEarly clinical trials with the Endeavor zotarolimus eluting stent (ZES) in western populations demonstrated low rates of target lesion revascularization with a favorable safety profile including low late stent thrombosis with up to 5 years of follow-up. The aim of this clinical registry study was to evaluate real world clinical performance of the ZES coronary system in Chinese patients.

METHODSThe China Endeavor Registry is a prospective, multicenter registry assessing the safety of the ZES system in a real world patient population. It was conducted at 46 centers in China in routine treatment of patients with coronary artery stenosis, including patients with clinical characteristics or lesion types that are often excluded from randomized controlled trials. The registry included 2210 adult patients who underwent single-vessel or multi-vessel percutaneous coronary intervention. The primary end point was the rate of major adverse cardiac events (MACE) at 12 months.

RESULTSThe 12-month rate of MACE for all patients in the registry was 3.03%. Cardiac death or myocardial infarction rate was 1.28% and target lesion revascularization rate was 1.66%, non-target lesion target vessel revascularization (TVR) was 0.52%, TVR was 2.18%, and target vessel failure was 3.22%. There was only one case of emergent cardiac bypass surgery. The 12-month overall incidence of all Academic Research Consortium (ARC)-defined stent thrombosis was 0.43%.

CONCLUSIONMid-term results from the real-world China Endeavor Registry suggest that Endeavor ZES was safe and effective in Chinese patients.

OBJECTIVE: The purpose of this study was to determine the serum uric acid levels and the prevalence of hyperuricemia among Chinese adults in 2015 and compare the differences between urban and rural areas, as well as the differences between eastern, central, and western regions. METHODS: A national representative sample of 180,208 participants were included using a stratified, multistage, and random sampling method. The demographic characteristics and blood samples were collected to determine the serum uric acid levels and prevalence of hyperuricemia among subgroups using complicated sampling weight. A t-test or ANOVA was used for normally-distributed data. The Kruskal-Wallis rank test was used for skewed-distributed data. The Mantel-Haenszel chi-square test was used to compare the difference in categorical variables. RESULTS: The weighted mean uric acid level in Chinese adults was 310.4 μmol/L (317.5 μmol/L in urban areas and 302.9 μmol/L in rural areas). The weighted average values of uric acid in eastern, central, and western China were 315.5 μmol/L, 303.5 μmol/L, and 310.4 μmol/L, respectively. The weighted prevalence of hyperuricemia in Chinese adults was 14.6%, with a prevalence of 16.5% in urban areas and 12.5% in rural areas. The weighted prevalence of hyperuricemia in eastern, central, and western China was 16.0%, 12.5%, and 14.8%, respectively. CONCLUSION The uric acid level in Chinese adults is relatively high. Effective actions are warranted to improve this metabolic abnormality.

OBJECTIVES: To study the effect of glucose metabolism disorders on the short-term prognosis in neonates with asphyxia. METHODS: A retrospective analysis was performed on the medical data of the neonates with asphyxia who were admitted to 52 hospitals in Hubei Province of China from January to December, 2018 and had blood glucose data within 12 hours after birth. Their blood glucose data at 1, 2, 6, and 12 hours after birth (with an allowable time error of 0.5 hour) were recorded. According to the presence or absence of brain injury and/or death during hospitalization, the neonates were divided into a poor prognosis group with 693 neonates and a good prognosis group with 779 neonates. The two groups were compared in the incidence of glucose metabolism disorders within 12 hours after birth and short-term prognosis. RESULTS: Compared with the good prognosis group, the poor prognosis group had a significantly higher proportion of neonates from secondary hospitals (48.5% vs 42.6%, CONCLUSIONS Recurrent hyperglycemia in neonates with asphyxia may suggest poor short-term prognosis, and it is necessary to strengthen the early monitoring and management of the nervous system in such neonates.

Relevant research in recent years has demonstrated that the atrial fibrillation occurrence rate is significantly higher in patients with cirrhosis. The most common indication for long-term anticoagulant therapy is chronic atrial fibrillation. The use of anticoagulant therapy greatly reduces the incidence rate of ischemic stroke. Patients with cirrhosis combined with atrial fibrillation have an elevated risk of bleeding and embolism during anticoagulant therapy due to cirrhotic coagulopathy. At the same time, the liver of such patients will go through varying levels of metabolism and elimination while consuming currently approved anticoagulant drugs, thereby increasing the complexity of anticoagulant therapy. This article summarizes the clinical studies on the risks and benefits of anticoagulant therapy in order to provide a reference for patients with cirrhosis combined with atrial fibrillation.

The protective action and the relevant mechanism of Liuwei Wuling tablet on acute alcoholic hepatic injury in mice were investigated. All the C57BL/6 mice were divided randomly into 7 groups including blank, model, bifendate (150 mg•kg⁻¹, positive control) and experimental groups consisted of extremely low dose (0.1 g•kg⁻¹), low (0.5 g•kg⁻¹), upper (4 g•kg⁻¹) and high dose (8 g•kg⁻¹) of Liuwei Wuling tablet groups. The acute liver injury model was induced by modified method that the model, positive control and experimental groups were orally administrated 56% alcohol (6 g•kg⁻¹) twice at 12 hour intervals on the fifth day after drugs administration. After 12 hours, the mice were sacrificed to contribute blood and liver for biochemical and histological examinations. Compared with the model, the activities of ALT and AST in serum decreased significantly in different Liuwei Wuling tablet groups. Meanwhile, in liver tissue, the levels of TG, MDA, TNF-α and IL-1β reduced obviously while the GSH and SOD activities showed markedly increase with a dose-dependent manner. Correspondingly, the microscopically pathological differences of the liver tissue observed by HE and oil red O staining indicated that the liver cell swelling, hydropic degeneration and lipid droplets formation induced by alcohol were significantly improved, which suggested the Liuwei Wuling tablet can reduce the liver injure. In conclusion, the Liuwei Wuling tablet had the protective effect on acute alcoholic hepatic injury which maybe depended on the mechanism of relieving lipid peroxidation, elevating antioxidant enzymes activity, inhibiting oxidative stress and reducing inflammation factors expression.

The appropriate needle device is crucial for obtaining the curative effect of fire needling therapy. The article introduces the material specification, clinical operation, indications, characteristics and advantages of the contemporary traditional fire needling devices (e.g. He's fire needle and Shi 's fire needle) and the contemporary new-type ones (e.g. fire needling with filiform needle and micro-needle); and determines the innovations of modern fire needling. It is anticipated that the needle specifications, production process and operation standard of fire needling devices should be further unified so as to provide the references for the selection of fire needling devices in treatment based on clinical syndrome differentiation and expand the clinical application of fire needling therapy.
