Aim To investigate the effects of CPD1,a novel phosphodiesterase 5 inhibitor,on renal pathological phenotype and fibrotic protein expression in renal fibrosis model mice. Methods Male C57BL/6 J mice were divided into three groups randomly(sham group,UUO group and UUO+CPD1 group). Unilateral ureteric obstruction model was constructed by surgery,and CPD1(5 mg·kg-1·d-1)was administered by intragastric administration two hours after the modeling for seven days. HE and Sirius Red staining were used to observe the distribution of tissue structural lesions and fibrosis. Immunohistochemical staining and Western blot were used to detect the expression of fibronectin(FN),α-SMA,collagen-I and kidney injury molecule-1(Kim-1). Results Compared with sham operation group,the renal tubules of mice were dilated and accompanied by a large amount of inflammatory infiltration. Moreover,the expressions of FN,α-SMA,collagen-I and Kim-1 proteins increased significantly(P<0.05)in UUO group. CPD1 treatment improved the kidney structure and decreased the expression of collagen fibers. Furthermore,CPD1 inhibited the expression of FN,α-SMA,collagen-I and Kim-1 markedly(P<0.05). Conclusions Phosphodiesterase 5 inhibitor CPD1 alleviates the progression of renal fibrosis induced by unilateral ureteral obstruction through down-regulating ECM deposition in the extracellular matrix and expression of Kim-1. The specific mechanism remains to be further studied.

Interleukin-1 receptor associated kinase 4 (IRAK-4), acting as a serine threonine kinase, is considered as a key signal node for the transduction of IL-1R family and TLRs signal pathway. Studies have found that IRAK-4 has a hand in many signal pathways, involving the inflammatory response of human joints, intestines, liver and nervous system, as well as other autoimmune diseases. It is also one of the causes of drug resistance of some cancer cells. Therefore, IRAK-4 tends to be an effective therapeutic target for inflammatory diseases and cancer. The prospects for the development of drugs in this pathway is to develop novel IRAK-4 small molecule inhibitors and investigate their safety and effectiveness, enrich the clinical treatment of inflammatory and cancer diseases finally. This paper classified and summarized the latest research progress on small molecule inhibitors of IRAK-4 signaling pathway according to structures of the compounds, in order to provide assistances and references for the research and development of related drugs.

BACKGROUNDS:
Azithromycin mass drug administration (MDA) is a key part of the strategy for controlling trachoma. This systematic review aimed to comprehensively summarize the present studies of azithromycin MDA on trachoma; provide an overview of the impact of azithromycin MDA on trachoma in different districts; and explore the possible methods to enhance the effectiveness of azithromycin MDA in hyperendemic districts.
METHODS:
PubMed, Embase, the Cochrane Central Register of Controlled Trials, Web of Science, and ClinicalTrials.gov were searched up to February 2021 with no language restriction. Studies reporting the effect of azithromycin MDA on trachoma were included. Mathematical modeling studies, animal studies, case reports, and reviews were excluded. The trachomatous inflammation-follicular (TF) <5.0% was used to judge the effect of azithromycin MDA on eliminating trachoma as a public health problem. Two researchers independently conducted the selection process and risk of bias assessment.
RESULTS:
A total of 1543 studies were screened, of which 67 studies including 13 cluster-randomized controlled trials and 54 non-randomized studies were included. The effect of azithromycin MDA on trachoma was closely related to the baseline prevalence in districts. For the districts with baseline prevalence between 5.0% and 9.9%, a single round of MDA achieved a TF <5.0%. For the districts with baseline between 10.0% and 29.9%, annual MDA for 3 to 5 years reduced TF <5.0%. However, for the districts with high level of baseline prevalence (TF >30.0%), especially with baseline TF >50.0%, annual MDA was unable to achieve the TF <5.0% even after 5 to 7 years of treatment. Quarterly MDA is more effective in controlling trachoma in these hyperendemic districts.
CONCLUSIONS
Azithromycin MDA for controlling trachoma depends on the baseline prevalence. The recommendation by the World Health Organization that annual MDA for 3 to 5 years in the districts with TF baseline >10.0% is not appropriate for all eligible districts.

Objective: To investigate the safety and efficacy of pulmonary vein deployment technique for percutaneous closure of atrial septal defects (ASD) solely under echocardiography guidance. Methods: A total of 38 ASD patients received pulmonary vein deployment in our hospital from 2012-10 to 2016-09 since the conventional method could not deliver the occluder to correct place. The patients were with the mean age at (16.0±15.6) years, body weight at (37.2±22.9) kg and ASD diameter at (17.1±4.2) mm. Operative effect was assessed by echocardiography. Follow-up study was conducted at 1, 3, 6, 12 months post-operation and at each year thereafter. Results: 37 patients were successfully finished pulmonary vein deployment for percutaneous closure of ASD solely under echocardiography guidance. One patient was successfully treated by a controlled steerable sheath. The mean operative time was (25.2±5.1) min and mean diameter of ASD occluder was (22.9±5.6) mm. 2 patients had trivial residual shunt at the early post-operative stage. No peripheral vascular injury, pulmonary vein and cardiac perforation occurred. All 38 patients were recovered and discharged. The average in-hospital time was (2.9±0.7) days. The patients were followed-up for (23.9±15.4) months, without complications of residual shunt, pericardial effusion, aortic regurgitation and pulmonary vein stenosis. Conclusion: Pulmonary vein deployment technique for percutaneous closure of ASD solely under echocardiography guidance was safe and effective; it can avoid radiation damage and provided a simple and practical method for ASD patients who failed to conventional method under echocardiography guidance.

BACKGROUNDSeveral previous studies have shown that snoring is associated with glucose metabolism and the development of diabetes, but rare study has shown the association between snoring frequency and prediabetes, particularly in China. We hypothesized that individuals who snore might have a higher risk of prediabetes. This study aimed to investigate the association between self-reported snoring and prediabetes in a Chinese population.
METHODSA cross-sectional study was performed in three large communities of Beijing from December 2011 to August 2012 by recruiting individuals aged ≥40 years old. All participants were requested to complete a detailed questionnaire and undergo anthropometric measurements. A 75 g oral glucose tolerance test was performed in individuals without diabetes. Blood samples of all participants were collected; blood glucose and blood fat levels were measured. Multivariate logistic regression models were built to assess the association between snoring frequency and prediabetes.
RESULTSA total of 13,592 participants (female: 66.56%; mean age: 56.8 ± 7.9 years; mean body mass index: 25.5 ± 3.4 kg/m2) were included in the final analysis. Of these, 30.9% were diagnosed with prediabetes, while 41.3% and 25.4% had occasional and habitual snoring, respectively. Habitual snoring was associated with an increased risk of prediabetes (odds ratio [OR]: 1.3, 95% confidence interval [CI]: 1.1-1.4, P< 0.001), after adjusting for diabetes and sleep-related confounders in the multivariable models. Habitual snoring was also associated with isolated impaired fasting glucose (IFG; OR: 1.3, 95% CI: 1.0-1.6; P< 0.001) and isolated impaired glucose tolerance (IGT; OR: 1.3, 95% CI: 1.2-1.5; P< 0.001), but not IFG + IGT (OR: 1.1, 95% CI: 0.9-1.4; P = 0.281). When stratified by total cholesterol (TC) levels, this association between habitual snoring and prediabetes was observed only in individuals with TC <5.6 mmol/L (OR: 1.4, 95% CI: 1.2-1.6; P< 0.001).
CONCLUSIONSHabitual snoring is associated with prediabetes, but only in individuals with TC <5.6 mmol/L. Further prospective studies are needed to confirm this finding.

To establish a genetic susceptibility assessment model of lung cancer risk potentially associated with polycyclic aromatic hydrocarbon (PAH) inhalation exposure among non-smokers in China, a total of 143 patients with lung adenocarcinoma and 143 cancer-free individuals were recruited. Sixty-eight genetic polymorphisms in 10 pathways related to PAH metabolism and tumorigenesis were selected and examined. It was observed that 3 genetic polymorphisms, along with 10 additional genetic polymorphisms via gene-gene interactions, significantly influenced lung cancer risk potentially associated with PAH inhalation exposure. Most polymorphisms were associated with PAH metabolism. According to the established genetic susceptibility score (GSS), lung cancer risk increased with a rise in the GSS level, thereby indicating a positive dose-response relationship.

Objective To evaluate the usefulness of narrow-band imaging with magnification in differentiating colorectal lesions, and assess for a learning curve, to gave help for the clinician, who want to carry out the technique. Method We retrospectively analyzed the clinical data of 289 patients who underwent NBI combined with magnification by four endoscopic physician, from June, 2015 to June, 2016, all the lesions were biopsied, endoscopic treatment or postoperative pathology and pathological examination, and the Sano classification control. All lesions were divided into three groups according to the NBI combined with magnifying endoscopy, these three sets included both lesions requiring endoscopic treatment (e.g. target lesions) and lesions that were not, or could not be, treated by endoscopy (e.g. nontarget lesions). Each physician examined the target or non-target lesion reached 15 cases as a group. By assessing the diagnostic accuracy of the four physicians for each group of lesions, an associated learning curve of NBI combined with magnifying endoscopy was developed. Result In 289 patients, 372 lesions were found by colonoscopy. NBI combined with magnifying endoscopy was 95.1%, 98.0% and 92.0%, respectively, in the identification of tumor and non-neoplastic lesions. The accuracy of the diagnosis of target and non-target lesions was significantly higher in group 2 than in group 1 [81.7% vs 95.1% (P = 0.010) and 71.7% vs 93.4% (P = 0.000)]. There was no significant difference in the diagnostic accuracy between group 2 and group 3 (P = 0.984 and P = 0.117). Conclusion It is very useful to use narrow-band imaging and Sano CP analysis in the differential diagnosis of colorectal lesions. The endoscopists who had never used NBI or no knowledge of NBI can have effective and stable diagnostic accuracy after using NBI with magnification to diagnose 15 target and non-target lesions respectively.
