Objective To study the relationship of two variants( -871A/G and -336A/G) polymorphisms of the DC-SIGN gene with the susceptibility to pulmonary tuberculosis in Chinese population.Methods Two hundred and thirty-seven tuberculosis cases and 244 controls were genotyped by pyrosequencing in this case-control study. The analysis of the relationship of the -871A/G and -336A/G polymorphisms with their susceptibility of pulmonary tuberculosis(PTB) and the relationship of the two variants with their clinical correlation of tuberculosis was performed by chi-square test. Results The genotypic frequencies of A/G + G/G and A/A of - 871, 37.6%, 62.4% respectively in cases, and 43.4%, 56. 6%respectively in controls, had no significant difference in statistics. And the genotypic frequencies of A/G + G/G and A/A of -336, 12. 2% ,87.8% respectively in cases, and 14.3% ,85.7% respectively in controls, had also no statistical difference between two groups. Interestingly, a significant association is disclosed between the promoter variant - 336G allele and fever in patients ( P = 0. 037, OR = 0. 191, 95 % CI:0. 040-0. 907 ). Conclusion The single nucleotide polymorphism of -871A/G and -336A/G in DCSIGN gene promoter might not be associated with the susceptibility to tuberculosis in Chinese. Tuberculosis patients with -336G allele are significantly protected fever.

Postoperative complications of ERCP include pancreatitis,cholangitis,hemorrhage,mechanical damage (such as perforation) of the digestive tract and drug reaction.Since the the complications definition,surgical indications,operation technique,data collection and processing method were inconsistent,there were controversies for the incidences of complications after ERCP and its risk factors for different institutions.This paper discussed the evolution of ERCP risk factors,current situation and prophylaxis of major complications after ERCP and summarized the current research progress in order to provide theoretical help for prevention and prophylaxis of postoperative complications of ERCP.

Objective:To evaluate correlation between left ventricular mechanical contraction synchrony and left ventricular systolic function by gated myocardial perfusion imaging(GMPI) using Cadmium-Zine-Telluride (CZT) SPECT.Methods:Three hundred and forty three consecutive patients( 232 males, 111 females, age (60.08±12.88) years) who underwent CZT SPECT GMPI in Shanxi Cardiovascular Hospital between January and August 2019 were retrospectively analyzed. The Emory cardiac toolbox was used to process the imaging data, and the left ventricular systolic synchrony parameters and systolic function parameters were acquired, including peak phase(PP), phase standard deviation (PSD), phase histogram bandwidth(PHB), histogram skewness(HS), histogram kurtosis(HK), and end-diastolic volume( EDV), end-systolic volume (ESV), left ventrieular ejection fraction (LVEF). All patients were divided into 4 groups: the normal group (147 cases), ischemic cardiomyopathy group (114 cases), nonischemic cardiomyopathy without left bundle branch block (LBBB) group(50 cases)and nonischemic cardiomyopathy with LBBB group(32 cases). The relationship between systolic synchrony parameters and systolic function parameters were analyzed with Pearson correlation analysis.Results:Statistic results for all patients showed that PSD and PHB were well correlated with LVEF( r values: -0.790, -0.799, both P<0.01), but PP was poorly correlated with LVEF( r=-0.194, P<0.01); HS, HK were positively correlated with LVEF( r values: 0.767, 0.676, both P<0.01); PSD, PHB were positively correlated with ESV( r values: 0.778, 0.795, both P<0.01) and EDV ( r values: 0.722, 0.732, both P<0.01); but PP was poorly correlated with ESV( r=0.145, P<0.01) and not correlated with EDV ( r=0.095, P>0.01). HS, HK were negatively correlated with EDV and ESV ( r values: -0.700 to -0.580, all P<0.01). PSD and PHB showed negatively correlation with LVEF ( r values: -0.834 to -0.492, all P<0.01), while HS, HK showed positive correlation with LVEF ( r values: 0.243-0.792, all P<0.01) in normal group, the ischemic cardiomyopathy group, the nonischemic cardiomyopathy without LBBB group and the nonischemic cardiomyopathy with LBBB group. Conclusions:The left ventricular systolic synchrony parameters provided by CZT SPECT GMPI correlate well with the left ventricular systolic function parameters, and the worse systolic function, the worse systolic synchrony. Both ischemic cardiomyopathy and non-ischemic cardiomyopathy can affect left ventricular mechanical contraction synchrony, and the effect on contraction synchrony in non-ischemic cardiomyopathy patients with LBBB is greater.

Objective To investigate the changes of autophagy in rat lung tissues after acute spinal cord injury (ASCI) and the possible mechanisms.Methods Sixty-three female SD rats were divided into sham operation group (n =21) and spinal cord injury group (n =42),according to the random number table.The modified Allen method with the impact energy of 10 × 25 g · mm at the T10 vertebra was used for preparation of ASCI models.The rats were sacrificed at 6,12,24,48,72 hours,1 and 2 weeks after injury.Lung tissue damage and apoptosis were detected by HE staining and TUNEL method.The changes of autophagy and expressions of LC3-Ⅱ,P62,Beclin-1,interleukin (IL)-17A and Bcl-2 in lung were detected by Western blot and immunofluorescence.Results The pulmonary alveoli maintained normal structure in sham operation group,with no inflammation or pulmonary hemorrhage.Slight lung tissue damages were observed in spinal cord injury group at 12 h postinjury.Alveolar stroma widening,inflammatory infiltration,hemorrhage,and alveolar collapse became ingravescent at 24-72 hours postinjury.Numbers of apoptotic cells in spinal cord injury group were 551.22 ± 135.94,905.11 ±92.64,and 141.78 ± 30.86 respectively at 24,72 hours and 1 week postinjury,and were significantly increased at 24 and 72 hours postinjury,compared with sham operation group (P ＜ 0.05).Expression of LC3-II in spinal cord injury group was increased at 24-72 hours postinjury,compared with sham operation group (P ＜ 0.05).Expression of P62 in spinal cord injury group was up regulated at 24-72 hours postinjury,compared with sham operation group (P ＜ 0.05).Expression of Beclin-1 in spinal cord injury group was increased at 24 h postinjury and then dropped at 48-72 hours,compared with sham operation group (P ＜ 0.05).Expression of IL-17A in spinal cord injury group was increased at 24-48 hours,compared with sham operation group (P ＜ 0.05).Expression of Bcl-2 in spinal cord injury group was increased from 24 hours to 72 hours,compared with sham operation group (P ＜ 0.05).Conclusion Autophagosome formation is increased and accumulated in the lung tissues after ASCI,which might be related to the increased interaction between Beclin-1 and Bcl-2 because of the up regulation of Bcl-2 by IL 17A,ultimately leading to the inhibition of autophagy.
