OBJECTIVETo explore the effects of chloride channels on the regulation of platelet cytoplasmic free calcium concentration ([Ca2+]i) and platelet aggregation (PAG).

METHODSFreshly separated platelets were activated by thrombin. Chloride channel blockers DIDS or NFA and calcium channel blockers SK&F96365 or nifedipine were added to study the effects on platelet [Ca2+]i and PAG by a single reagent or the combination of reagents and find out the interactions among DIDS, NFA, SK&F96365 and nifedipine.

RESULTSBoth DIDS and NFA could inhibit the thrombin (1 U/ml) induced PAG in a dose-dependent manner, whereas had little effect on resting [Ca2+]i. As compared with the control group, DIDS, SK&F96365 and Nifedipine could significantly reduce the PAG, Ca2+ release and Ca2+ influx in thrombin activated platelet (P < 0.05). The combination of DIDS and SK&F96365 had greater effects in reducing the PAG, Ca2+ release and Ca2+ influx than either reagent alone (P < 0.05). The combination of DIDS and nifedipine also had greater effect than each alone in reducing Ca2+ release (P < 0.05). The combination of NFA and SK&F96365 weakened each other's effect on Ca2+ release (P < 0.05), while NFA and nifedipine weakened each other's effects on PAG, Ca2+ release and Ca2+ influx in thrombin activated platelet (P < 0.05).

CONCLUSIONDIDS and NFA have no effect on the resting [Ca2+]i and the leak calcium influx of platelet. DIDS can inhibit the Ca2+ release, Ca2+ influx and PAG of platelet induced by thrombin, while NFA can only inhibit the Ca2+ release. The chloride channel and calcium channel blockers have interactions in affecting resting [Ca2+]i and PAG of platelet. The opening of chloride channel can influence the cellular calcium movement of platelet.

OBJECTIVETo investigate the genetic etiologies in the 0- 3-years-old infants with hearing loss and to analyze the interaction between genetics and environmental factors.

METHODSTotal of 130 infants were performed detailed audiological evaluation as well as the detection of the popular deafness gene mutations in GJB2 gene, SLC26A4 and mtDNA12SrRNA. Of them, 84 cases were performed the computer tomography or magnetic resonance imaging examinations.

RESULTSOf the 130 cases, 54 infants were diagnosed as large vestibular aqueduct syndrome, while seven of 130 were as auditory neuropathy and the others were diagnosed as sensorineural hearing loss. Considering of the risks of etiologies for hearing loss, 85 of them had the experiences of the high risk factors at birth (65.4%, 85/130), while 23 of them had the exposure of aminoglycoside antibiotics, and 13 had the family history background as well as two cases were from the consanguineous families. In the causative genes screening, 42 infants were caused by the mutations of SLC26A4 gene (32.3%), but 14 infants found the mutations in GJB2 gene (4.6%), and no infants carried the mutation in mtDNA 12SrRNA 1555G and 1494T points in our studies.

CONCLUSIONSIn our studies, about 36.9% infants hearing loss cases can be found the mutations in SLC26A4 and GJB2 genes. It is essential to put the idea into the hearing evaluation combined with genetic testing for the diagnoses of hearing loss. It is also helpful for exploring the etiologies of hearing loss and performing the target genetic consulting for decreasing the prevalence of deafness in the future.

OBJECTIVETo explore the effects of long-term exposure to particulate matter 2.5 (PM2.5) from automobile exhaust on the reproductive function of Sprague Dawley (SD) rats.

METHODSForty-five male SD rats, weighing 80 - 94 g and aged 28 days, were randomly assigned to receive intra-tracheal administration of 0.9% normal saline (control group, n = 15), PM2. 5 at 2 μg per 100 g body weight per day (low-dose PM2.5 group, n = 15), and PM2.5 at 16 μg per 100 g body weight per day (high-dose PM2.5 group, n = 15), qd, for 60 successive days. After the last 24-hour exposure, 10 rats were taken from each group for copulation with normal female ones, while the others were sacrificed, their testes removed for sperm count and deformity, pathological examination, and determination of the Connexin43 expression.

RESULTSThe conception rate was significantly decreased in the low- and high-dose PM2.5 groups as compared with that of the control (70% and 50% vs 100%), and so were the sperm count and quality. The rats in the PM2.5-exposed groups showed significantly disordered histological structure of the seminiferous tubules, reduced sperm count in the testicular lumen, some exfoliated secondary spermatocytes, downregulated Connexin43 expression in the testis, and damaged blood-testis barrier.

CONCLUSIONLong-term exposure to PM2.5 from automobile exhaust damages the reproductive function of male SD rats.

OBJECTIVETo observe the anti-virus effects of andrographolide (AD) on the retinoic acid-inducible gene-I (RIG-I)-like receptors (RLRs) signaling pathway when immunological cells were infected with H1N1.

METHODSLeukomonocyte was obtained from umbilical cord blood by Ficoll density gradient centrifugation, and immunological cells were harvested after cytokines stimulation. Virus infected cell model was established by H1N1 co-cultured with normal human bronchial epithelial cell line (16HBE). The optimal concentration of AD was defined by methyl-thiazolyl-tetrazolium (MTT) assay. After the virus infected cell model was established, AD was added into the medium as a treatment intervention. After 24-h co-culture, cell supernatant was collected for interferon gamma (IFN-γ) and interleukin-4 (IL-4) enzyme-linked immunosorbent assay (ELISA) detection while immunological cells for real-time polymerase chain reaction (RT-PCR).

RESULTSThe optimal concentration of AD for anti-virus effect was 250 μg/mL. IL-4 and IFN-γ in the supernatant and mRNA levels in RLRs pathway increased when cells was infected by virus, RIG-I, IFN-β promoter stimulator-1 (IPS-1), interferon regulatory factor (IRF)-7, IRF-3 and nuclear transcription factor κB (NF-κB) mRNA levels increased significantly (P<0.05). When AD was added into co-culture medium, the levels of IL-4 and IFN-γ were lower than those in the non-interference groups and the mRNA expression levels decreased, RIG-I, IPS-1, IRF-7, IRF-3 and NF-κB decreased significantly in each group with significant statistic differences (P<0.05).

CONCLUSIONSThe RLRs mediated viral recognition provided a potential molecular target for acute viral infections and andrographolide could ameliorate H1N1 virus-induced cell mortality. And the antiviral effects might be related to its inhibition of viral-induced activation of the RLRs signaling pathway.

Objective:To investigate the clinical features and prognosis of male with anti-melanoma differentiation-associated gene 5 (MDA5) autoantibody.Methods:The clinical data of 246 patients with DM and anti-MDA5 autoantibodies hospitalized by Jiangsu Myositis Cooperation Group from 2017 to 2020 were collected and retrospectively analyzed. Chi-square test was performed to compared between counting data groups; Quantitative data were expressed by M ( Q1, Q3), and rank sum test was used for comparison between groups; Single factor survival analysis was performed by Kaplan-Meier method and Log rank test; Cox regression analysis were used for multivariate survival analysis. Results:①The male group had a higher proportion of rash at the sun exposure area [67.1%(47/70) vs 52.8%(93/176), χ2=4.18, P=0.041] and V-sign [50.0%(35/70) vs 30.7%(54/176), χ2=8.09, P=0.004] than the female group. The male group had higher levels of creatine kinase [112(18, 981)U/L vs 57 (13.6, 1 433)U/L, Z=-3.50, P<0.001] and ferritin [1 500 (166, 32 716)ng/ml vs 569 (18, 14 839)ng/ml, Z=-5.85, P<0.001] than the female group. The proportion of ILD [40.0%(28/70) vs 59.7%(105/176), χ2=7.82, P=0.020] patients and the red blood cell sedimentation rate[31.0(4.0, 101.5)mm/1 h vs 43.4(5.0, 126.5)mm/1 h, Z=-2.22, P=0.026] in the male group was lower than that of the female group, but the proportion of rapidly progressive interstitial lung disease (PR-ILD) [47.1%(33/70) vs 31.3%(55/176), χ2=5.51, P=0.019] was higher than that of the female group. ②In male patients with positive anti-MDA5 antibodies,the death group had a shorter course of disease[1.0(1.0, 3.0) month vs 2.5(0.5,84) month, Z=-3.07, P=0.002], the incidence of arthritis [16.7%(4/24) vs 42.2%(19/45), χ2=4.60, P=0.032] were low than those in survival group,while aspartate aminotransferase (AST)[64(22.1, 565)U/L vs 51(14,601)U/L, Z=-2.42, P=0.016], lactate dehydrogenase (LDH) [485(24,1 464)U/L vs 352(170, 1 213)U/L, Z=-3.38, P=0.001], C-reactive protein (CRP) [11.6(2.9, 61.7) mg/L vs 4.95(0.6, 86.4) mg/L, Z=-1.96, P=0.050], and ferritin levels [2 000(681, 7 676) vs 1 125 (166, 32 716)ng/ml, Z=-3.18, P=0.001] were higher than those in the survival group, and RP-ILD [95.8%(23/24) vs 22.2%(10/45), χ2=33.99, P<0.001] occurred at a significantly higher rate. ③Cox regression analysis indicated that the course of disease LDH level, and RP-ILD were related factors for the prognosis of male anti-MDA5 antibodies [ HR (95% CI)=0.203(0.077, 0.534), P=0.001; HR (95% CI)=1.002(1.001, 1.004), P=0.003; HR (95% CI)=95.674 (10.872, 841.904), P<0.001]. Conclusion:The clinical manifestations of male anti-MDA5 antibody-positive patients are different from those of female. The incidence of ILD is low, but the proportion of PR-ILD is high. The course of disease, serum LDH level, and RP-ILD are prognostic factors of male anti-MDA5 antibody-positive patients.

OBJECTIVETo compare the short-term outcomes of surgical treatment for non-small cell lung cancer (NSCLC) by video-assisted thoracoscopic surgery (VATS) and open thoracotomy (OT).

METHODSData of 737 consecutive NSCLC patients who underwent surgical treatment for non-small cell lung cancer by video-assisted thoracoscopic surgery and 630 patients who underwent pulmonary resection via open thoracotomy (as controls) in Cancer Institute & Hospital, Chinese Academy of Medical Sciences between January 2009 and August 2011 were retrospectively reviewed. The risk factors after lobectomy were also analyzed.

RESULTSIn the 506 NSCLC patients who received VATS lobectomy, postoperative complications occurred in 13 patients (2.6%) and one patient died of acute respiratory distress syndrome (0.2%). In the 521 patients who received open thoracotomy (OT) lobectomy, postoperative complications occurred in 21 patients (4.0%) and one patient died of pulmonary infection (0.2%). There was no significant difference in the morbidity rate (P > 0.05) and mortality rate (P > 0.05) between the VATS group and OT group. In the 190 patients who received VATS wedge resections, postoperative complications occurred in 3 patients (1.6%). One hundred and nine patients received OT wedge resections. Postoperative complications occurred in 4 patients (3.7%). There were no significant differences for morbidity rate (P = 0.262) between these two groups, and there was no perioperative death in these two groups. Univariate and multivariate analyses demonstrated that age (OR = 1.047, 95%CI: 1.004 - 1.091), history of smoking (OR = 6.374, 95%CI: 2.588 - 15.695) and operation time (OR = 1.418, 95%CI: 1.075 - 1.871) were independent risk factors of postoperative complications.

CONCLUSIONSTo compare with the NSCLC patients who should undergo lobectomy or wedge resection via open thoracotomy, a similar short-term outcome can be achieved via VATS approach.

OBJECTIVETo evaluate the effect of elective microscopic resection of dorsal penile nerves in the treatment of primary premature ejaculation (PPE).

METHODSSeventy-eight PPE patients received elective microscopic resection of dorsal penile nerves, 5 branches in 9 cases, 6 in 17, 7 in 15, 8 in 14, 9 in 8, 10 in 6, 11 in 6, and 12 in 3. The patients were followed up for 12 months, and their intravaginal ejaculation latency time (IELT) and sexual intercourse satisfaction scores were recorded before and after treatment.

RESULTSCompared with the baseline, the IELT was significantly prolonged after surgery ([0.86 +/- 0.32] vs [6.65 +/- 3.9] min, P < 0.01), and the sexual intercourse satisfaction scores of the patients were dramatically increased (7.32 +/- 2.52 vs 12.32 +/- 3.76, P < 0.01), so were those of their sexual partners (4.46 +/- 1.36 vs 12.73 +/- 1.45, P < 0.01).

CONCLUSIONElective microscopic resection of dorsal penile nerves is safe and effective for the treatment of PPE.
