BACKGROUND:Cytochrome P450 ( CYP) epoxygenases metabolize arachidonic acids ( AA) to form epoxyeicosatrienoic acids
(EETs), which exert beneficial roles in the treatment of cardiovascular diseases , but little is known about its role on adventitial remo-deling.METHODS:We used C57BL/6J mice in vivo and primary rat adventitial fibroblasts ( AFs) in vitro treated with angiotensin II (Ang II) to investigate the effects of CYP2J2 gene delivery and exogenous EETs administration on adventitial remodeling .RESULTS:CYP/sEH system was found to exist in human adventitia , and involved in adventitial remodeling process .Exogenous EETs administra-tion significantly inhibited Ang II-induced AFs activation , characterized by differentiation , proliferation, migration, and collagen syn-thesis.These protective effects were partially reversed by PPARγantagonist GW9662 pretreatment or SOCS3 siRNA transfection.EETs suppressed Ang II-induced IκBαphosphorylation , subsequent NF-κB nuclear translocation via PPARγdependent signaling pathway in AFs.Additionally, EETs reduced Ang II-induced JAK2, STAT3 phosphorylation and subsequent phosphor-STAT3 nuclear transloca-tion, which were mediated by SOCS3 induction but independent of PPARγactivation.Furthermore, rAAV-CYP2J2 gene delivery re-duced vessel wall thickening , AFs differentiation , proliferation and collagen deposition in aortic adventitia induced by Ang II infusion , which were mediated by NF-κB and SOCS3/JAK/STAT signaling pathways in blood pressure-dependent and -independent manners , re-spectively.CONCLUSION:We concluded that CYP2J2 overexpression attenuated Ang II-induced adventitial remodeling via PPARγ-dependent NF-κB and PPARγ-independent SOCS 3/JAK/STAT inflammatory signaling pathways .

Objective To explore the effect of Drotaverine hydrochloride on preventing bladder spasm after transurethral prostatectomy.Methods 124 patients after transurethral prostatectomy were divided into patient-controlled epidural analgesia pump group (group I, n=61) and Drotaverine hydrochloride group (group II, n=63). Group I received bupivacaine by patient-controlled epidural analgesia, and the pump was withdrawed after 72 h. Group II received Drotaverine hydrochloride by intramuscular injection, 80 mg every 12 h, and then orally taken after anal exhaust for 3 days. Bladder spasm and adverse reaction were recorded in both groups. Results There was no significant difference in bladder spasm between group I (11.48%) and group II (12.70%) (P>0.05), as well as in side reaction between group I (16.39%) and group II (17.46%) (P>0.05). Conclusion Drotaverine hydrochloride is effective on preventing bladder spasm after transurethral resection of the prostate, with small side effect.

Objective To investigate preliminarily the value of phrenic nerve conduction (PNC) and diaphragmatic motor evoked potentials (MEPs) in the evaluation of various respiratory dysfunction (RDF).Methods Thirty-four patients with various RDF, (19 patients with neurogenical diseases and 15 patients with respiratory disorders) were investigated. Fifty healthy volunteers served as controls. The phrenic nerve was cutaneously stimulated by electrical pulse current at the midpoint of the posterior border of the sternomastoid muscle, and the diaphragmatic muscle compound action potentials (DCAP) were recorded between the 7th and 8th intercostal space and xiphoid process. When the magnetic transcranial stimulation (MTS) of the cortex was given, the recordings were made under the condition of maximal deep inspiration.Results All patients with myopathies had normal PNC. The patients with Guillain Barre syndrome (GBS), hereditary motor and sensory neuropathy (HMSN) and myasthenic crisis had abnormal PNC. The findings in PNC studies remarkably correlated with RDF, while serial examinations were performed in the patients with GBS and myasthenia gravis (MG). In 7 patients with sleep apnea syndrome (SAS), 4 had abnormal PNC, and 2 of 3 patients with chronic obstructive pulmonary diseases (COPD), and 1 of 5 patients with chest tightness or breathlessness on the supine position showed decreased amplitude. When MEPs were recorded, 3 of 5 patients showed abnormal SAS (1 had no response, 2 lower amplitude). Three patients with COPD had normal MEP.Conclusions PNC studies could not only evaluate neuromuscular RDF and predict the outcome of diseases, but also supply additional information about diaphragmatic dysfunction for the RDF caused by respiratory disorders. The results of PNC and diaphragmatic MEP may differentiate the types of SAS.

Objective:To analyze the clinical and molecular genetic characteristics of a Chinese family with congenital cataract-microcornea syndrome.Methods:The method of pedigree investigation was adopted.A Chinese Han family with congenital cataract-microcornea syndrome was recruited in Xiamen Eye Center of Xiamen University.All the family members received detailed ophthalmologic examination including the best corrected visual acuity, intraocular pressure measurement by handheld applanation tonometry, slit lamp biomicroscopy, color fundus photography, B-scan ultrasonography, corneal diameter, anterior segment optical coherence tomography, ultrasound biomicroscopy, corneal endoscopy, and corneal topography.Genomic DNA was extracted from peripheral venous blood from some patients and unaffected family members.Targeted high-throughput DNA sequencing was performed on the proband.The sequencing chip contained 188 known pathogenic genes related to lens abnormalities.Suspected pathogenic genes were verified by Sanger sequencing in phenotypically normal family members to identify the co-segregation and the disease-causing gene.Bioinformatics analysis was performed to analyze the pathogenicity of variants by REVEL.Conserved protein domains were analyzed by InterPro.Physicochemical property of the mutant protein was analyzed by ProtParam.The deleteriousness of the protein was predicted by PolyPhen-2.Homology of the variants in pathogenic gene was analyzed by NCBI website to compare the conservation among various species.This study followed the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Xiamen Eye Center of Xiamen University (No.XMYKZX-LW-2009-003).Written informed consent was obtained from each subject prior to entering the study cohort.Results:There were 39 members of 4 generations in this family including 11 patients with an autosomal dominant inheritance pattern.Clinical features of the patients included congenital cataract and microcornea.No obvious abnormality was found in ophthalmic and general examination.A heterozygous mutation c. 61C>T in the CRYAA gene was found, resulting in the mutation of the amino acid from arginine to tryptophan (p.Arg21Trp) at position 21, consistent with co-segregation.The number of cationic cluster in the mutant protein decreased, and the hydrophilicity and stability were reduced.The variant was predicted to be deleterious and was highly conserved in multiple species. Conclusions:A novel heterozygous mutation c.61C>T p. Arg21Trp in CRYAA gene is considered as the causal gene of this family.It is the first time this variant has been reported in China.

We conducted a randomized, open-label, parallel-controlled, multicenter trial on the use of Shuanghuanglian (SHL), a traditional Chinese patent medicine, in treating cases of COVID-19. A total of 176 patients received SHL by three doses (56 in low dose, 61 in middle dose, and 59 in high dose) in addition to standard care. The control group was composed of 59 patients who received standard therapy alone. Treatment with SHL was not associated with a difference from standard care in the time to disease recovery. Patients with 14-day SHL treatment had significantly higher rate in negative conversion of SARS-CoV-2 in nucleic acid swab tests than the patients from the control group (93.4% vs. 73.9%, P = 0.006). Analysis of chest computed tomography images showed that treatment with high-dose SHL significantly promoted absorption of inflammatory focus of pneumonia, which was evaluated by density reduction of inflammatory focus from baseline, at day 7 (mean difference (95% CI), -46.39 (-86.83 to -5.94) HU; P = 0.025) and day 14 (mean difference (95% CI), -74.21 (-133.35 to -15.08) HU; P = 0.014). No serious adverse events occurred in the SHL groups. This study illustrated that SHL in combination with standard care was safe and partially effective for the treatment of COVID-19.
