ABSTRACT
OBJECTIVE@#To explore the genetic basis for 4 patients with globozoospermia.@*METHODS@#Semen and blood samples were collected from the patients for the determination of sperm concentration, viability, survival rate, morphology and acrosome antigen CD46. Meanwhile, DNA was extracted for whole exome sequencing (WES), and candidate variants were validated by Sanger sequencing.@*RESULTS@#All of the four patients were found to harbor variants of the DPY19L2 gene. Patients 1 ~ 3 had homozygous deletions of the DPY19L2 gene. Sanger sequencing confirmed that the DPY19L2 gene in patient 3 was disrupted at a recombination breakpoint area BP2, resulting in nonallelic homologous recombination and complete deletion of the DPY19L2 gene. Patients 2 and 3 respectively harbored novel homozygous deletions of exons 2 ~ 22 and exons 14 ~ 15. Patient 4 harbored heterozygous deletion of the DPY19L2 gene, in addition with a rare homozygous deletion of the 3' UTR region.@*CONCLUSION@#DPY19L2 gene variants probably underlay the globozoospermia in the four patients, which has fit an autosomal recessive pattern of inheritance and the characteristics of genomic diseases.

Objective To investigate the application value of pre-implantation genetic testing(PGT)in patients with Turner syndrome.Methods The clinical data,embryonic development,PGT results and pregnancy outcome of 18 patients with Turner syndrome who underwent PGT in the reproductive center of 900th Hospital from January 2016 to June 2023 were retrospectively analyzed.Results All 18 patients had spontaneous puberty development,of which 4 patients had primary ovarian insufficiency(POI).A total of 24 oocyte retrieval cycles were performed in 18 patients,of which 6 patients had no biopsied embryos for 10 cycles.Sixty-one embryos were biopsied and 60 embryos were clearly diagnosed,including 25 with chromosomal abnormalities.Seven patients with mosaic Turner syndrome obtained clinical pregnancies after transplantation,including 4 healthy boys had already been delivered and 3 are in pregnancy.Conclusion There are numerous types of karyotype in Turner syndrome.The clinical phenotypes vary greatly in individuals with Turner syndrome,and prognosis of PGT is significant different.Patients with Turner syndrome who had biopsied embryos can obtain available embryo using PGT,and achieve ideal clinical outcomes.
ABSTRACT
Objective To explore the classification and changes of macrophage subsets in liver transplant rejection.Methods Rat liver transplantation model were established and divided into immune tolerance group(B-B),where the liver of BN rat donors was transplanted to BN rat recipients,and immune rejection group(L-B),in which the liver of Lewis rat donors was transplanted to BN rat recipients.Single-cell RNA sequencing and high-throughput RNA sequencing were used to distinguish the macrophage subsets of rat liver transplantation,and to find differential gene in rejection reactions.Immunohistochemistry was used to determine the changes and distribu-tion of protein expression and cell subsets.Results CD68 positive macrophages were higher in the rejection group than that in the tolerance group(P<0.05),and macrophages could be divided into 9 subsets.During the rejection reaction,the CXC chemokine ligand 9(CXCL9)in the 8th subsets of macrophages was significantly increased,while the gene for white blood cell differentiation antigen 74(CD74)in the 5th subsets was significantly increased(P<0.05).CD74 ranked first in the differential gene synthesis of macrophages during rejection,followed by CXCL9.Compared with the tolerance group,a large number of CD74 positive macrophages were observed in the hepatic portal area of the rejection group,and the infiltration of CD74 positive macrophages in the hepatic sinuses was also significantly increased(P<0.05),while a large number of CXCL9 positive macrophages were observed in the hepatic portal area and hepatic sinuses of the rejection group,especially in the portal area(P<0.05),and CD14 positive cells were significantly increased(P<0.05).Conclusions The CD74 positive macrophage subsets and CXCL9 positive macrophage subsets may be key subgroups in promoting liver transplant rejection,improving the mechanism of macrophage action in liver transplant rejection.

ABSTRACT
Purpose@#Pancreatic duct decompression relieves pancreatic duct stone (PDS)-associated abdominal pain, though a consensus indication for the drainage procedure of the main pancreatic duct (MPD) is lacking. Moreover, major prognostic factors for postsurgical long-term pain relief and recurrence are largely unknown. @*Methods@#The clinical outcomes of 65 consecutive PDS patients undergoing surgery from 2008–2012 with 3+ years of follow-up were assessed. @*Results@#At postsurgical follow-up (median, 4.5 years; range, 3–7 years; procedure: Partington, n = 32; Frey, n = 27; pancreatoduodenectomy, n = 3; distal pancreatectomy, n = 3), the early complication and complete stone clearance rates were 29.2% and 97%, respectively. Long-term, complete and partial pain relief were 93.9%, 83.1%, and 10.8%, respectively. The risk of pancreatic fistula was higher in the 8 mm group (P < 0.05), and 80% of the pancreatic fistula cases occurred in the <8 mm group. A shorter pain duration (P = 0.007), smaller MPD diameter (P = 0.04), and lower Izbicki pain score (P < 0.001) predicted long-term pain relief. Pain recurrence after initial remission occurred in 5 patients and was only related to pain duration (P = 0.02). Stone recurrence and pancreatic exocrine functional and endocrine functional deterioration occurred in 2, 5, and 11 patients, respectively. @*Conclusion@#Surgery provides excellent stone clearance, long-term pain relief, and acceptable postoperative morbidity. Using 8 mm as the criterion for drainage surgery can minimize the postoperative pancreatic fistula risk. Individualized and timely surgical treatment may improve the effect of surgery.
ABSTRACT
Objective:To report on 3 patients who presented with rupture of hepatic artery pseudoaneurysm after liver transplantation.Methods:From April 2010 to April 2019, 3 patients with hepatic artery pseudoaneurysm rupture after liver transplantation treated at the Department of Hepatobiliary and Pancreatic Surgery, Henan Provincial People's Hospital were studied. The possible causes, clinical manifestations, diagnosis and treatment were retrospectively analyzed.Results:Rupture of hepatic artery pseudoaneurysm occurred on the19th, 28th and 63th days after transplantation. The 3 patients all presented with hematochezia and abdominal pain, while 2 patients presented with hematemesis. Two patients had bile leakage and abdominal infection. All the 3 patients presented with fever. Patient 1 who was diagnosed by laparotomy died of liver failure. Patient 2 underwent interventional embolization of hepatic artery and died of liver failure also. Patient 3 underwent surgical resection of the pseudoaneurysm followed by hepatic artery reconstruction, but died of repeat abdominal hemorrhage.Conclusion:Hepatic artery pseudoaneurysm after liver transplantation has a long latent period and is difficult to diagnose at an early stage. Early detection of this life-threatening complication is the key to improve survival. Early treatment of biliary leakage, abdominal infection and other complications help to prevent development of pseudoaneurysms.
ABSTRACT
Objective@#To investigate the application value of multiple-arterial-phase imaging technique with differential sub-sampling with cartesian ordering (DISCO) in the gadoxetate acid disodium enhanced liver MRI.@*Methods@#From September 2017 to March 2018, 56 patients with suspected malignant focal liver disease diagnosed with ultrasound or CT in West China Hospital of Sichuan University were enrolled prospectively, and underwent preoperative enhanced MRI with gadoxetate acid disodium. Patients were divided into 2 groups by random-number table method. Twenty nine patients in group A underwent liver multiple-arterial-phase imaging with DISCO. Twenty seven patients in group B underwent single-arterial-phase imaging with liver acquisition with volume acceleration-flex (LAVA-Flex). The display rate of late-arterial-phase and respiratory motion artifacts of dynamic enhancement images were evaluated. The categorical variables was compared by Chi-square test. The respiratory motion artifacts between the single-arterial-phase and multiple-arterial-phases were compared by Mann-Whitney U test. The artifact scores among the various phases of the multi-arterial phase were compared by Kruskal-Wallis H.@*Results@#Compared to LAVA-Flex [74.1%(20/27)], a higher display rate of late-arterial phase [96.6%(28/29)] was found in DISCO (Group A), and the difference was statistically significant (χ2=5.770, P=0.016). In the evaluation of respiratory motion artifacts, the motion artifacts of the late-arterial images obtained by LAVA-Flex [3(3,4)] were more severe than the DISCO [2(2,3)], and the difference was statistically significant (Z=-3.250, P<0.01). Among the scores of motion artifacts in the 6 phases of DISCO, the artifact scores of phase 1, 2, 3, 4, 5, 6 were [3(3,4)], [2(2,3)], [2(2,3)], [3(2,3)], [3(3,4)] and [3(3,4)], respectively. The motion artifacts of phase 2, 3, 4 were better than phase 1, 5, 6, the differences were statistically significant (P<0.05), but there was no statistical differences among phase 2, 3 and 4 (P>0.05).@*Conclusion@#Compared with single-arterial-phase imaging, multiple-arterial-phases with DISCO using gadoxetate acid disodium can improve the capture rate of late arterial phase and reduce motion artifacts.
ABSTRACT
Objective@#To investigate the value of multi-arterial phase differential sub-sampling with cartesian ordering (DISCO) technique in the evaluation of hepatic vascular anatomy with gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid (Gd-EOB-DTPA).@*Methods@#Forty-eight patients with suspected hepatic malignancy were prospectively enrolled and underwent both of Gd-EOB-DTPA enhanced DISCO MRI and CTA within two weeks. The hepatic arterial anatomy of two examination methods were evaluated by four-point scoring method. The arterial scores between DISCO and CTA images were compared by Wilcoxon test. The difference among multiple arterial scores of DISCO and CTA were compared by Kruskal-Wallis H test respectively.@*Results@#There was no difference of arterial scores in celiac artery, common hepatic artery, proper hepatic artery, left hepatic artery, right hepatic artery, first branch of right hepatic artery, splenic artery, left gastric artery and gastroduodenal artery between DISCO and CTA (P>0.05), but the arterial score of first branch of left hepatic artery [2 (2,2)] was lower than that of CTA [2 (2,3)] (Z=-3.138,P=0.002). In the multiple comparison among different arteries, there were differences between PHA and LAH (P<0.05), B-LHA and B-RHA (P<0.05) in DISCO, but no difference was found in CTA (P>0.05).@*Conclusion@#The DISCO sequence with Gd-EOB-DTPA enhancement MRI can supply comparable image quality to CTA in hepatic artery and its main branches display, which has no ionizing radiation and can also provide more diagnostic information for clinic.

ABSTRACT
Qi arrival is the meridian qi response to acupuncture stimulation. Through analyzing the relevant concepts of qi arrival and summarizing the general understanding of it in clinic and on the basis of the collection of the relevant literature at home and abroad on the determination of qi arrival and its strength, the characteristics are analyzed on the present method and the method for the determination of qi arrival and its strength is discussed in terms of the results in the needling sensation scale. It is believed that the needling sensation and its strength can be used to determine whether the qi is arrived or not and its strength. The components of different types of needling sensation are much better applicable for the analysis on the characteristics and rules on the influence on qi arrival. This method is in compliance not only with the theoretic connotation of qi arrival, but also with the clinical general understanding, which lays the foundation for the analysis on the scale results.

ABSTRACT
<p><b>OBJECTIVE</b>To screen for esophageal squamous cell carcinoma (ESCC)-associated long non-coding RNAs (lncRNA) and identify oncogenic lncRNA contributing to ESCC pathogenesis.</p><p><b>METHODS</b>A lncRNA array containing 7419 lncRNA was used to detect the transcriptional profiles of lncRNA of four pairs of ESCC and matched normal esophageal tissue. Bioinformatic analysis was employed to identify differentially expressed ESCC associated lncRNA (ESCCAL). Quantitative real-time PCR was used to verify selected dysregulated lncRNA on independent ESCC samples.</p><p><b>RESULTS</b>Genome-wide transcriptome profiling (coding and or noncoding RNA transcripts) was able to distinguish ESCC from normal tissue. Among these, bioinformatic analysis has identified 154 differentially expressed ESCC associated lncRNA (ESCCALs), which included 111 downregulated and 43 upregulated lncRNA in ESCC relative to the normal tissue (P< 0.01). The highest upregulated lncRNA (ESCCAL_1) and known onco-lncRNA HOTAIR was further verified in 26 paired ESCC samples. ESCCAL_1 and HOTAIR were found to be highly expressed in 17 ESCC and 18 ESCC compared with normal esophageal tissues.</p><p><b>CONCLUSION</b>This investigation has revealed large scale aberrant expression of lncRNA in ESCC. About 70% of novel lncRNA-ESCCAL_1, together with a known lncRNA-HOTAIR, are highly expressed in ESSC, suggesting that ESCCAL_1 and HOTAIR may participate in the pathological process of ESCC. Furthermore, lncRNA could be potential diagnostic and prognostic biomarkers for ESCC.</p>
