Transcatheter aortic valve replacement(TAVR)is currently one of the main therapeutic strategies for aortic valve disease.Preoperative imaging assessment is crucial for operation project planning and prevention of procedure-associated complications.Different from planar image reconstruction,3D printing technology can accurately depict the anatomical structure of the aortic root.It enables further assessment of operative risk and therapeutic strategy through in vitro simulation,especially for assessing the risk of coronary artery obstruction and planning interventional procedures.Here,we report on two patients who underwent a 3D printing aortic root anatomical simulation model,followed an by in vitro balloon dilatation/valve implantation test,to evaluate the risk of coronary artery obstruction suggested by CT angiography planar image reconstruction before TAVR.

To investigate the relationship between male semen parameters and sperm DNA fragment index with age. Adopt cross-sectional sampling survey design, 3 203 male patients who visited the Department of Reproductive Andrology in the Third Affiliated Hospital of Zhengzhou University from January 2019 to June 2021 were selected as subjects. Age range is 18-57 years, with the median age of 30 years. Through quartile regression analysis, the correlation between age and different male semen parameters and DNA fragment index (DFI) was presented. The study population was divided into ≤30 years old group and >30 years old group, and the correlation between age and semen volume, sperm concentration, total sperm count, progressive motility, total motility, percentage of normal sperm and DFI level were compared and analyzed. The results showed that there were significant differences in progressive motility, total motility and DFI level among different age groups (χ²=-4.608, -4.604, -7.719,P all <0.05), but there was no significant difference in semen volume, sperm concentration, total sperm count and percentage of normal sperm (χ²=-1.712, -1.203, -0.149, -0.175,P all >0.05). In the>30 years old age group, there was a very weak negative correlation between male age and semen volume, progressive motility and total motility (r=-0.137, -0.101 and -0.056, P all <0.05). There was a very weak positive correlation between male age and sperm concentration and sperm DFI level (r=0.061, 0.190, P all <0.05), while there was no correlation between male age and total sperm count and percentage of normal sperm (r=-0.018, -0.016,P all >0.05). In conclusion, with the increase of age, especially after the age of 30, semen volume, progressive motility and total motility decreased, while sperm concentration and DFI level increased, and semen quality decreased.

Mitral regurgitation(MR)is a common valvular heart disease in China,the prevalence of which increases with age,and most patients present with a wide range of cardiac or non-cardiac comorbidities.Transcatheter mitral valve edge-to-edge repair(TEER)has become a guideline-recommended,safe and effective treatment option for patients with severe primary or secondary mitral regurgitation.With the rapid development of TEER technology in China,relevant devices have been developed and approved for clinical trials,including the self-designed and manufactured JensClip system,which adopts a unique slider locking design to realize the innovation of mitral clip locking mode.Here we reported a case of JensClip device in treatment of a patient with degenerative mitral regurgitation(DMR).

ObjectiveTo establish the determination for index components in benchmark samples of Erdongtang， and clarify the content and transfer rate rages of index components in 15 batches of benchmark samples， and to explore the quantity transfer of index components of decoction pieces to benchmark samples. MethodFifteen batches of benchmark samples were prepared， the contents of mangiferin， baicalin and glycyrrhizic acid were determined by high performance liquid chromatography （HPLC）-diode array detector （DAD）， the mobile phase was acetonitrile （A）-0.1% formic acid aqueous solution （B） for gradient elution （0-10 min， 10%-17%A； 10-25 min， 17%-19%A； 25-28 min， 19%-25%A； 28-45 min， 25%-33%A； 45-46 min， 33%-45%A； 46-60 min， 45%-55%A）， detection wavelength was set at 254 nm. Contents of timosaponin BⅡ and the sum of protoneodioscin and protodioscin were determined by HPLC-evaporative light scattering detector （ELSD）， the mobile phase was acetonitrile （A）-water （B） for gradient elution （0-20 min， 24%A； 20-25 min， 24%-27%A； 25-33 min， 27%-28%A； 33-36 min， 28%-90%A； 36-41 min， 90%-24%A）. ResultThe methodological verification of the established method was good， which could be used for determination of five index components in benchmark samples. The content ranges of mangiferin， baicalin， glycyrrhizic acid， timosaponin BⅡ， and the sum of protoneodioscin and protodioscin in 15 batches of benchmark samples of Erdongtang were 0.14%-0.23%， 2.40%-3.37%， 0.07%-0.44%， 0.43%-0.95%， and 0.15%-0.47%， the transfer rate ranges of them were 33.90%-52.15%， 84.46%-105.61%， 22.59%-93.86%， 38.07%-61.43%， and 53.28%-96.11%， respectively. ConclusionThe consistencies of transfer rate of mangiferin， baicalin， timosaponin BⅡ and the sum of protoneodioscin and protodioscin （except glycyrrhizic acid） between decoction pieces and benchmark samples of Erdongtang are good， indicates that the transfer rates of 4 index components are stable during the preparation process of benchmark samples， which can provide data support for research and development of the compound preparation of this formula.

BACKGROUND: Prospective analyses have yet to identify a consistent relationship between sleep duration and the incidence of gastrointestinal (GI) cancers. The effect of changes in sleep duration on GI cancer incidence has scarcely been studied. Therefore, we aimed to examine the association between baseline sleep duration and annual changes in sleep duration and GI cancer risk in a large population-based cohort study. METHODS: A total of 123,495 participants with baseline information and 83,511 participants with annual changes in sleep duration information were prospectively observed from 2006 to 2015 for cancer incidence. Cox proportional-hazards models were used to calculate hazard ratios (HRs) and their confidence intervals (CIs) for GI cancers according to sleep duration and annual changes in sleep duration. RESULTS: In baseline sleep duration analyses, short sleep duration (≤5 h) was significantly associated with a lower risk of GI cancer in females (HR: 0.31, 95% CI: 0.10-0.90), and a linear relationship between baseline sleep duration and GI cancer was observed (P = 0.010), especially in males and in the >50-year-old group. In the annual changes in sleep duration analyses, with stable category (0 to -15 min/year) as the control group, decreased sleep duration (≤-15 min/year) was significantly associated with the development of GI cancer (HR: 1.29; 95% CI: 1.04-1.61), especially in the >50-year-old group (HR: 1.32; 95% CI: 1.01-1.71), and increased sleep duration (>0 min/year) was significantly associated with GI cancer in females (HR: 2.89; 95% CI: 1.14-7.30). CONCLUSIONS Both sleep duration and annual changes in sleep duration were associated with the incidence of GI cancer.

Objective:To establish the quality evaluation methods of Asparagi Radix decoction pieces and its standard decoction. Method:Ten batches of Asparagi Radix standard decoction were prepared. High performance liquid chromatography-evaporative light scattering detection method (HPLC-ELSD) was established for the determination of protodioscin and protoneodioscin in Asparagi Radix decoction pieces and its standard decoction, and the fingerprint detection of Asparagi Radix decoction pieces with acetonitrile-water as mobile phase for gradient elution. UHPLC-LTQ-Orbitrap-MS/MS was used to identify ten main common peaks in the fingerprint with acetonitrile-0.1% formic acid solution as mobile phase for gradient elution, electrospray ionization (ESI) and positive and negative ion mode scanning were employed, the detection range was m/z 100-1 400. Result:The total content of protodioscin and protoneodioscin in Asparagi Radix decoction pieces was 0.41%-0.72%, and their total content in Asparagi Radix standard decoction was 0.33%-0.59%, the transfer rate of these two components was 73.6%-98.3%. The dry extract yield of the standard decoction was 59.0%-73.0%, and its pH was 4.9-5.6.
