Objective To investigate the relationship between serum anticardiolipin antibody-immune globulin G (ACA-IgG),interleukin-10 (IL-10 ),IL-17 levels and intracranial large-artery atherosclerotic stenosis in patients with ischemic stroke. Methods From March 2014 to March 2015,a total of 176 consecutive patients with the first-ever ischemic stroke admitted to the Department of Neurology,Liaocheng People′s Hospital,Shandong Province,China,and performed DSA were enrolled prospectively. Seven of the patients with cardiogenic embolism,5 with moyamoya disease,8 with arteritis,2 with artery dissection,9 with autoimmune diseases or acute and chronic inflammation were excluded,21 with extracranial arterial stenosis were not enrolled,and finally 124 were enrolled in the study. According to the findings of DSA,the degrees of intracranial large artery stenosis were divided into a stenosis-free group (n = 34),a mild-stenosis group (n = 30),a moderate-stenosis group (n = 32),and a severe-stenosis group (n = 28). The differences of serum ACA-IgG,IL-10,IL-17 levels and baseline factors of the 4 groups were compared,and multivariate logistic regression analysis was used to analyze several factors that affected intracranial large-artery stenosis. Results There were no significant differences in sex,age,alcohol consumption rate,smoking rate,and incidence of hyperlipidemia among the 4 groups of patients (all P >0. 05). Compared with the stenosis-free group,there were significant differences in the incidences of hypertension and diabetes among the mild-stenosis,moderate-stenosis and severe-stenosis groups (the incidence of hypertension,80. 0% [n = 24],93. 8% [n = 30],89. 3% [n = 25]vs. 55. 9% [19 cases];χ2 = 8. 271,8. 920,and 10. 877,respectively;P = 0. 038,0. 032,and 0. 014,respectively). The incidences of diabetes were 33. 3% (n = 10),43. 8% (n = 14),60. 7% (n = 17)vs. 8. 8% (n = 3),(χ2 = 7. 960, 8. 733,and 9. 285,respectively;P = 0. 043,0. 035,and 0. 027,respectively). Incidence of diabetes of the severe-stenosis group was higher than that of the mild-stenosis group (χ2 = 9. 348,P = 0. 025). There were no significant differences in the incidences of hypertension and diabetes among other groups (all P >0. 05). There were significant differences in ACA-IgG levels (23 ± 5,39 ± 8,51 ± 9,and 65 ± 10 kU/ L);IL-10 levels (108 ± 33,85 ± 25,77 ± 21,and 62 ± 19 ng/ L),and IL-17 levels (38 ± 10,58 ± 22,63 ± 31, and 75 ± 26 ng/ L)among the stenosis-free,mild,moderate and severe-stenosis groups (F = 17. 754,9. 827, and 12. 656;respectively;all P < 0. 01). Compared with the stenosis-free group,the ACA-IgG and IL-17 levels of the patients in the mild,morderate,and severe stenosis groups increased significantly (ACA-IgG level:t =2. 307,2. 559,and 3. 374,respectively;P = 0. 026,0. 014,and 0. 001,respectively,the IL-17 levels:t =2. 183,2. 549 and 3. 159,respectively;P = 0. 037,0. 013,and 0. 002,respectively),while the IL-10 level decreased significantly. There were significant differences among the groups (t = 2. 036,2. 351,and 2. 762, respectively;P = 0. 042,0. 023,and 0. 006,respectively). Compared with the mild-stenosis group,the ACA-IgG and IL-17 levels of the severe stenosis group increased significantly (t = 3. 154 and 2. 976 respectively;P = 0. 002 and 0. 004 respectively). There were no significant differences among the pairwise comparisons of other groups (P >0. 05). The results of logistic regression analysis showed that hypertension, diabetes,ACA-IgG level,and IL-17 level were the risk factors for intracranial large-artery stenosis (OR, 3. 043,95% CI 1. 606 -5. 875,P = 0. 003;OR,2. 912,95% CI 1. 513 -5. 824,P < 0. 01;OR,1. 837,95% CI 2. 057-3. 416,P = 0. 037;OR,1. 453,95% CI 1. 346 -2. 721,P = 0. 014). Conclusion ACA-IgG and IL-17 may play an important role in the occurrence and development processes of intracranial large-artery atherosclerotic stenosis.

Objective:To prepare dendritic cell (DC)-cytokine induced killer (CIK) tumor vaccine using DCs of patients with nonsmall-cell lung cancer (NSCLC) harboring autologous tumor antigens and to observe its inhibitory effect on autologous tumor cells in vitro. Methods: Peripheral blood mononuclear cells (PBMCs) extracted from NSCLC patients were cultured into DCs and CIKs in presence of different cytokines. Cancer cells from the patients were cultured in vitro and were used to prepare different tumor antigens: tumor cell lysates, necrotic tumor cells and normally-grown tumor cells. The DCs were stimulated by OK-432 and the phenotypes of the DCs were analyzed by flow cytometer. Then the DCs were co-cultured with CIKs. The anti-tumor effect of DC-CIK was evaluated by MTT assay. Results: Compared with the DCs harboring the antigens of necrotic tumor cells and normally-grown tumor cells, DCs pulsed with tumor cell lysates had significantly higher expression of surface molecules such as CD1a (85.1?2.7), CD80 (80.0?4.4), CD83 (75.4?5.3), and HLA-DR(80.5?7.8, all P

Fetal cystic lymphangioma is a developmental anomaly of the lymphatic system, which can occur in any part of the body, but most commonly in the neck and armpit. A case of fetal cystic lymphangioma located at the chest wall under the right armpit with a size of 21 mm×18 mm×16 mm is reported here. The mass was initially diagnosed by routine ultrasound examination at 21 gestational weeks. After the diagnosis, ultrasound was repeated every 4 weeks till 37 +4 gestational weeks. Over this period, the mass increased progressively to 101 mm×110 mm×95 mm. Ultrasound-guided intrauterine fetal cystic mass puncture and aspiration was performed 38 +4 weekss, and Bleomycin was injected into the cyst after operation and on day 42 after birth. During a follow-up to 10 months after birth, no obvious cystic mass was found at the right axillary chest wall of the child.

Objective:To compare the clinical effects between the homodigital radial flap of the dorsal cutaneous branch of radial palmar proper digital artery (PPDA) and the homodigital reverse island flap of the ulnar dorsal digital artery (DDA) on reconstruction of defects in thumb-tip or thumb-pulp.Methods:The retrospective case-control study method was used. From January 2016 to August 2022, a total of 65 thumb-tip or thumb-pulp defects were treated in the Department of Hand Surgery of the Second Hospital of Tangshan. Thirty-five defects of thumbs were reconstructed with the homodigital radial flap pedicled with dorsal cutaneous branch of radial PPDA (PPDA group) and the other 30 thumbs were treated by the homodigital ulnar reverse island flap pedicled with ulnar DDA (DDA group). Sizes of the wounds and flaps in PPDA group were 1.9 cm×1.5 cm to 2.9 cm×2.4 cm and 2.1 cm× 1.7 cm to 3.1 cm×2.6 cm, respectively, and the dimensions of the wounds and flaps in DDA group were 2.0 cm× 1.7 cm to 2.9 cm×2.5 cm and 2.2 cm×1.9 cm to 3.2 cm×2.8 cm, respectively. The wounds of donor site in both groups were all directly closed. Survival of the flaps and wound healing of donor sites were observed in both groups. The time of surgery and duration of follow-up of the 2 groups were recorded. Postoperative follow-up included outpatient clinic visits, telephone reviews and WeChat video-clips. At the final follow-up, record of total active motion (TAM) of the injured thumbs, angle of first web of the affected hands, static TPD of the flaps, patient satisfaction of the appearance of flaps and donor sites were taken. According to the Michigan Hand Function Questionnaire (MHQ) evaluation criteria, the patient satisfaction of the appearance of flaps and donor sites were evaluated. The measurement and count data acquired from both groups were compared by independent sample t-test and χ2 tests or Fisher's exact test, respectively. P<0.05 was considered statistically significant. Results:All 35 flaps in PPDA group and 26 flaps in DDA group survived primarily, except 4 flaps in the DDA group that showed blisters and healed with dressing changes. The primary survival rate of flap in PPDA group (100%) was higher than that of DDA group (87%), and the difference was statistically significant ( P<0.05). Donor sites of both groups healed primary. The time of surgery and duration of follow-up in PPDA and DDA groups were 59.11 minutes±5.42 minutes and 15.37 months±3.32 months, and 61.27 minutes±5.96 minutes and 16.17 months±3.60 months, respectively. There was no statistically significant difference between the 2 groups ( P>0.05). At the final follow-up, the thumb TAM and angle of thumb web in PPDA and DDA groups were 135.14°±10.04° and 90.29°±4.36° and 132.17°±11.04° and 89.00°±4.81°, respectively. There was no statistically significant differences between the 2 groups ( P>0.05). The static TPD, patient satisfaction of the appearance of flaps and donor sites in PPDA group were 7.11 mm±1.21 mm, 4.69 point±0.47 point and 4.43 point±0.50 point, which were better than DDA group [8.20 mm±1.47 mm, 4.40 point±0.50 point and 4.13 point±0.57 point, respectively] with a statistically significant difference ( P<0.05). Conclusion:The homodigital radial flap of the dorsal cutaneous branch of radial PPDA and the homodigital ulnar reverse island flap of the ulnar DDA are both suitable for reconstruction of defects in thumb-tip or thumb-pulp. Compared with the homodigital reverse island flap with the DDA, a homodigital radial flap with the dorsal cutaneous branch of PPDA has advantages in higher primary survival rate, better flap sensation and appearance at both of recipient and donor sites.

The importance of structural variants(SVs)for human phenotypes and diseases is now recognized.Although a variety of SV detection platforms and strategies that vary in sensitivity and specificity have been developed,few benchmarking procedures are available to confidently assess their performances in biological and clinical research.To facilitate the validation and application of these SV detection approaches,we established an Asian reference material by characterizing the genome of an Epstein-Barr virus(EBV)-immortalized B lymphocyte line along with identified benchmark regions and high-confidence SV calls.We established a high-confidence SV callset with 8938 SVs by integrating four alignment-based SV callers,including 109x Pacific Biosciences(PacBio)continuous long reads(CLRs),22 x PacBio circular consensus sequencing(CCS)reads,104x Oxford Nanopore Technologies(ONT)long reads,and 114×Bionano optical mapping plat-form,and one de novo assembly-based SV caller using CCS reads.A total of 544 randomly selected SVs were validated by PCR amplification and Sanger sequencing,demonstrating the robustness of our SV calls.Combining trio-binning-based haplotype assemblies,we established an SV benchmark for identifying false negatives and false positives by constructing the continuous high-confidence regions(CHCRs),which covered 1.46 gigabase pairs(Gb)and 6882 SVs supported by at least one diploid haplotype assembly.Establishing high-confidence SV calls for a benchmark sample that has been characterized by multiple technologies provides a valuable resource for investigating SVs in human biology,disease,and clinical research.
