RESUMEN
Objective:To investigate the level change of cytokines in patients with Epstein-Barr virus (EBV)-associated hemophagocytic lymphohistiocytosis (EBV-HLH).Methods:A retrospective case control study was conducted. The clinical data of 65 patients with EBV-HLH, 30 patients with infectious mononucleosis (IM) (IM group) and 40 patients with non-EBV infection-associated hemophagocytic lymphohistiocytosis (non-EBV-HLH group) who admitted to Tongji Hospital,Tongji Medical College of Huazhong University of Science and Technology from February 2022 to February 2023 were retrospectively analyzed. The enzyme-linked immunosorbent assay (ELISA) was used to detect the expression levels of the interleukin (IL)-6, IL-2, IL-10, IL-8, IL-1β, tumor necrosis factor-α (TNF-α) and interferon γ (IFN-γ) in serum samples of patients in the above 3 groups. The cytokines levels in EBV-HLH group were compared with those in IM group and non-EBV-HLH group, respectively.Results:The cytokines levels of IL-6, IL-2, IL-10, IL-8, IL-1β, TNF-α and IFN-γ in EBV-HLH group were higher than those in the non-EBV-HLH group, and the differences were statistically significant (all P < 0.05). The cytokines levels of IL-2, IL-10 and IFN-γ in EBV-HLH group were higher than those in IM group, and the differences were statistically significant (all P < 0.05). Conclusions:The cytokines levels of IL-6, IL-2, IL-10, IL-8, IL-1β, TNF-α, IFN-γ are increased in EBV-HLH patients, which may play an important role in the development and progression of EBV-HLH.
RESUMEN
Objective:To evaluate the feasibility and clinical effectiveness of placing a nasointestinal ileus tube (NTI) during extensive adhesive bowel obstruction (ABO) surgery.Methods:A retrospective analysis was performed for the clinical and follow-up data of 60 patients with extensive ABO admitted to the Department of General Surgery of Daxing District Hospital of Capital Medical University from April 2019 to April 2021, of which 30 patients underwent intraoperative NIT intraintestinal alignment (observation group) and 30 patients who did not undergo NIT intraintestinal alignment (control group) during the same period. There were 12 males and 18 females in the observation group. There were 16 males and 14 females in the control group. The operation time, gastrointestinal function recovery time, discharge time, total effective rate and postoperative complication rate were compared between the two groups, and the quantitative data of the recurrence rate of intestinal obstruction at 24 months after surgery were expressed as mean ± standard deviation ( ± s), and the t-test was used for comparison between groups. Numerological data were presented as cases (percentage) [ n (%)], and chi-square tests were used for comparison between groups. Results:All patients were successfully completed the surgery and discharged from the hospital. There was no statistically significant difference in total effective rate between the control group and the observation group( χ2=3.16, P=0.237). The surgical time in the observation group was slightly longer than that in the control group [(110.6±4.6) min vs (94.3±2.5) min, t=17.27, P=0.001]. The recovery time of gastrointestinal function and hospitalization time in the observation group were shorter than those in the control group[(8.13±1.00) d vs (8.70±0.70) d, t=2.53, P=0.014; (12.83±1.57) d vs (13.67±1.03) d, t=0.03, P=0.018]. The incidence of postoperative complications was lower than that in the control group (10% vs 30%, P=0.028), and the difference was statistically significant. Conclusion:Intraoperative application of NIT is safe and effective, and can significantly reduce the recurrence rate of postoperative intestinal obstruction.

RESUMEN
BACKGROUND:Previous brain studies have mostly focused on adults and fetuses,and the developmental characteristics of young children's brainstems have rarely been studied. OBJECTIVE:To observe the brainstem development characteristics of healthy young children and to explore the age-related differences and their correlation with sex. METHODS:From January 2019 to April 2022,a retrospective study of 3.0T MRI images of 174 children aged 2 to 6 years in the Affiliated Hospital of Inner Mongolia Medical University was conducted,and the median sagittal diameter,area and angle of the brainstem(including midbrain,pons and medulla oblongata)were measured. RESULTS AND CONCLUSION:There is an age-related increase in the anterior and posterior diameters of the midbrain,pons and medulla oblongata in the 2-5 years old group as well as in the longitudinal diameter and area of the midbrain,pons and medulla oblongata in the 2-6 years old group.Except for the longitudinal diameter of the medulla oblongata,all others show a positive correlation with age(r>0,P<0.05).In the 2-3 years old group and 4-5 years old group,the children are in the rapid growth and development stage,and these two age groups can be used as the key observation indicators for the development of young children.The anterior-posterior diameter,longitudinal diameter,area of the pons and total brainstem area are strongly correlated with age,which can be used as the key observation indicators for the brainstem development in young children.

RESUMEN
Objective:To explore the effectiveness and safety of focused ultrasound ablation surgery (FUAS) for abdominal wall endometriosis.Methods:From November 2019 to October 2022, a total of 34 patients with abdominal wall endometriosis who underwent FUAS were collected, and their clinical features, imaging features, intraoperative treatment and side effects after treatment were analyzed retrospectively, and the improvement of symptoms and re-intervention were followed up.Results:(1) Characteristics of clinical data: the average age of 34 patients with abdominal wall endometriosis was (32.8±3.8) years old. The largest diameter of the lesion was 48 mm, and the median lesion diameter was 24 mm. Thirty cases (88%, 30/34) had moderate to severe periodic pain in abdominal incision before FUAS. All patients were diagnosed by preoperative magnetic resonance imaging, including 19 cases (56%, 19/34) of superficial type, 8 cases (24%, 8/34) of intermediate type and 7 cases (21%, 7/34) of deep type. (2) FUAS treatment parameters: ablation was completed with average operation time of (64±18) minutes, average sonication time was (385±108) s, (103±11) W of average power, (38 819±16 309) J of average total energy, the average treatment area volume of (3.11±1.42) cm 3, and (377.79±106.34) s/h of average treatment intensity. (3) Efficiency: the pain of patients after FUAS was significantly relieved, and the pain scores of patients after 1 month, 3 months, 6 months and 1 year after FUAS were significantly decreased ( Z=-4.66, -5.13, -5.11 and -4.91, all P<0.01). One year after FUAS, the near relief and effective pain relief rate was 74% (25/34), and the clinical effective rate was 85% (29/34). Five patients recurred after one year, including 3 patients who underwent abdominal wall endometriosis lesion resection and 2 patients who received drug treatment. One month after FUAS, the size of the lesion did not change significantly compared with that before FUAS ( P>0.05), and the size of the lesion decreased significantly after FUAS at 3 months, 6 months and 1 year ( Z=-2.15, -2.67 and -3.41, all P<0.05). It has no difference in pain relief among different types ( P>0.05), but has significant difference in focus reduction among three types ( P<0.01). (4) Safety: there were 34 cases (100%, 34/34) of skin burning sensation, 19 cases (56%, 19/34) of pain in the treatment area and 2 cases (6%, 2/34) of hematuria. All patients got better after corresponding treatments. Conclusion:FUAS is safe and effective for the treatment of abdominal wall endometriosis, which has clinical application value.
RESUMEN
【Objective】 To investigate the prevalence of Hepatitis E virus (HEV) among blood donors in Wuhan urban agglomeration, aimed at providing data support for the development of HEV screening strategies for blood donors. 【Methods】 A total of 3 329 blood samples were collected from four centralized testing areas (Ezhou, Tianmen, Xiantao and Qianjiang) and screened at Wuhan Blood Center from January to December 2021. Among them, 2 737 were eligible blood samples with normal ALT (ALT normal group) and 592 were with elevated ALT (ALT elevated group). Enzyme linked immunosorbent assay (ELISA) was used to detect anti-HEV IgG, anti-HEV IgM and HEV-Ag, and Real-time PCR was used to perform single HEV RNA detection on blood samples with elevated ALT and normal ALT anti-HEV IgM+ blood samples. A two-sided Pearson’s chi-squared test or Fisher's exact test was used to evaluate the differences in the positive rates of anti-HEV IgG and anti-HEV IgM in different regions and ALT groups. 【Results】 The overall positive rates of anti-HEV IgG, anti-HEV IgM, and HEV-Ag in 3 329 blood samples from four regions were 21.63%, 1.29%, and 0%, respectively. There was a significant difference in the positive rates of anti-HEV IgG among blood donors in different regions (P<0.05). The highest positive rate of anti-HEV IgG was found in Tianmen 29.44% (136/462), followed by Qianjiang 22.69% (236/1 040), Xiantao 22.66% (230/1 015), and Ezhou 14.53% (118/812). The positive rates of anti-HEV IgG and anti-HEV IgM in blood samples with elevated ALT were significantly higher than that in normal ALT samples (25.68% vs 20.75%, 2.53% vs 1.02%, both P<0.05). However, none of the samples was HEV RNA positive. 【Conclusion】 HEV is prevalent among blood donors in Wuhan urban agglomeration with extremely low current infection rates, and the prevalence of anti-HEV IgG serum varies among different regions. The prevalence of anti-HEV antibodies in blood donors with elevated ALT is significantly higher than that in normal ALT donors.
RESUMEN
Objective:To evaluate the correlation and consistency between quantitative coronary flow fraction (QFR) and cardiac magnetic resonance imaging (CMR) in assessing myocardial ischemia in patients with coronary heart disease (CAD).Methods:A retrospective analysis was conducted on the data of coronary heart disease patients who underwent load CMR examination and coronary angiography at the Beijing Anzhen Hospital, Capital Medical University from August 2017 to March 2022. CMR examination includes cardiac cine, load/rest myocardial perfusion imaging, and delayed enhancement sequence. According to the results of CMR examination, the patient′s left ventricular myocardial segments were divided into normal segment group and abnormal segment group (further divided into ischemic segment group and infarcted segment group). On the basis of coronary angiography, an artificial intelligence based platform (AngioPlus system) was applied to calculate the preoperative coronary artery QFR value of patients undergoing percutaneous coronary intervention treatment. Kappa test was used to evaluate the consistency of QFR and CMR in diagnosing abnormal myocardium; Mann Whitney U test was used to compare the differences in QFR between groups; The receiver operating characteristic (ROC) curve was used to evaluate the efficacy of QFR in diagnosing abnormal myocardium; Spearman correlation analysis was used to clarify the relationship between myocardial infarction area and QFR value of the supplying coronary artery in patients.Results:Among the 70 CAD patients enrolled, there were 60 males and 10 females, aged (54.1±11.1)years. At the vascular level, the consistency between QFR and CMR in diagnosing myocardial injury (including ischemia and infarction) is moderate (Kappa value=0.514). The sensitivity and specificity of detecting abnormal myocardial segments in CAD patients were 57% and 91%, respectively. The area under the curve (AUC) value of QFR predicting abnormal myocardium in CAD patients was 0.769, and the optimal cutoff value was QFR=0.865. At this time, the sensitivity and specificity of QFR predicting myocardial injury in CAD patients were 67.2% and 84.3%, respectively. The difference in vascular QFR between the normal segment group, ischemic segment group, and infarcted segment group was statistically significant ( P<0.001), with the infarcted segment group having significantly lower QFR values than the other two groups (all P<0.01). The range of myocardial infarction was negatively correlated with the QFR value of the supplying coronary artery ( r=-0.45, P<0.001). At the patient level, the consistency between QFR and CMR in diagnosing myocardial injury (including ischemia and infarction) was moderate (Kappa value=0.445), with a sensitivity of 74% and a specificity of 81% for diagnosing myocardial injury in CAD patients. Conclusions:Compared with CMR, QFR has better specificity in detecting myocardial injury in CAD patients. The QFR value of the infarcted segment group is significantly lower than that of the ischemic group and the normal group. The area of myocardial infarction is negatively correlated with the QFR value of the supplying coronary artery.
RESUMEN
AIM: To observe the effects of Liuwei Dihuang Tang on the expression levels of ferritin, recombinant solute carrier family 7 member 11(SLC7A11), glutathione(GSH), and glutathione peroxidase 4(GPX4)in retinal of aging model rats.METHODS: A total of 45 SD rats were randomly divided into a blank group, a model group, and a traditional Chinese medicine(TCM)group, with 15 rats in each group. The blank group was intraperitoneally injected with physiological saline, while the model group and TCM group were intraperitoneally injected with D-galactose [500 mg/(kg·d)]. At the same time, the TCM group was orally administered with Liuwei Dihuang Tang [6.75 g/(kg·d)], while the blank group and model group were orally administered with equal volume of physiological saline for 8 consecutive wk. The expression levels of ferritin, SLC7A11, GSH, and GPX4 in the retinal tissues of rats in each group were detected.RESULTS: The expression of ferritin in the retinal tissue of the model group was increased compared to the blank group(P<0.05), while the expression of GSH, SLC7A11, and GPX4 was reduced(P<0.05). The expression of GSH, SLC7A11, and GPX4 in the retina tissue of rats in the TCM group was higher than that in the model group(P<0.05).CONCLUSIONS: Liuwei Dihuang Tang may exert a delaying effect on retinal aging by regulating the ferroptosis pathway.
RESUMEN
Prostate cancer is currently one of the most common malignancies that endanger the lives and health of elderly men. In recent years, immunotherapy, which exploits the activation of anti-cancer host immune cells to accomplish tumor-killing effects, has emerged as a new study avenue in the treatment of prostate cancer. As an important component of immunotherapy, cancer vaccines have a unique position in the precision treatment of malignant tumors. Monocyte cell vaccines, dendritic cell vaccines, viral vaccines, peptide vaccines, and DNA/mRNA vaccines are the most often used prostate cancer vaccines. Among them, Sipuleucel-T, as a monocyte cell-based cancer vaccine, is the only FDA-approved therapeutic vaccine for prostate cancer, and has a unique position and role in advancing the development of immunotherapy for prostate cancer. However, due to its own limitations, Sipuleucel-T has not been widely adopted. Meanwhile, owing to the complexity of immunotherapy and the specificity of prostate cancer, the remaining prostate cancer vaccines have not shown good clinical benefit in large randomized phase II and phase III trials, and further in-depth studies are still needed.

Objective: To clarify the phenotypes of the newborns with SLC26A4 single-allele mutation in deafness genetic screening and second variant; to analyze the SLC26A4 genotype and hearing phenotype. Methods: 850 newborns born in Beijing from April 2015 to December 2019 were included and there were 468 males and 382 females. They received genetic deafness screening for 9 or 15 variants, with the result of SLC26A4 single-allele mutation. Firstly, three step deafness gene sequencing was adopted in this work, i.e., the first step was "SLC26A4 gene whole exons and splice sites" sequencing; the second step was "SLC26A4 gene promoter, FOXI1 gene and KCNJ10 gene whole exons" sequencing; and the third step was detection for "SLC26A4 gene copy number variation". Secondly, we collected the results of newborn hearing screening for all patients with the second mutation found in the three step test, and conducted audiological examinations, such as acoustic immittance, auditory brainstem response and auditory steady state response. Thirdly, for novel/VUS mutations, we searched the international deafness gene database or software, such as DVD, ClinVar and Mutation Taster, to predict the pathogenicity of mutations according to the ACMG guideline. Lastly, we analyzed the relationship between genotype and phenotype of newborns with SLC26A4 single allele mutation. Results: Among 850 cases, the median age of diagnosis was 4 months. In the first step, 850 cases were sequenced. A total of 32 cases (3.76%, 32/850) of a second variants were detected, including 18 cases (2.12%, 18/850) with identified pathogenic variants; 832 cases were sequenced and 8 cases of KCNJ10 gene missense variants were detected among the second step. No missense mutations in the FOXI1 gene and abnormal SLC26A4 gene promoter were detected; the third step sequencing results were all negative. Genotypes and hearing phenotypes included 18 cases combined with the second clear pathogenic variant, 16 cases (16/18) referred newborn hearing screening and 2 cases (2/18) passed in both ears; degree of hearing loss consisted of 18 profound ears (18/36), 13 severe ears (13/36) and 5 moderate ears (5/36); audiogram patterns comprised 17 high frequency drop ears (17/36), 14 flat ears (14/36), 3 undistinguished ears (3/36), and 2 U shaped ears (2/36); 11 cases underwent imaging examination, all of which were bilateral enlarged vestibular aqueduct. As for 22 cases of other genotypes, all passed neonatal hearing screening and the hearing diagnosis was normal, including 9 cases with VUS or possibly novel benign variants, 8 cases with KCNJ10 double gene heterozygous variants, and 5 cases with double heterozygous variants. Conclusions: The probability of individuals with SLC26A4 single-allele variant who merge with a second pathogenic variant is 2.12%, all of which are SNV, which can provide scientific basis for the genetic diagnosis and genetic counseling of SLC26A4 variants. Those who have merged with second pathogenic variant are all diagnosed with sensorineural hearing loss. Patients with KCNJ10 gene mutations do not manifest hearing loss during the infancy, suggesting the need for further follow-up.

The emerging of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) caused COVID-19 pandemic. The first case of COVID-19 was reported at early December in 2019 in Wuhan City, China. To examine specific antibodies against SARS-CoV-2 in biological samples before December 2019 would give clues when the epidemic of SARS-CoV-2 might start to circulate in populations. We obtained all 88,517 plasmas from 76,844 blood donors in Wuhan between 1 September and 31 December 2019. We first evaluated the pan-immunoglobin (pan-Ig) against SARS-CoV-2 in 43,850 samples from 32,484 blood donors with suitable sample quality and enough volume. Two hundred and sixty-four samples from 213 donors were pan-Ig reactive, then further tested IgG and IgM, and validated by neutralizing antibodies against SARS-CoV-2. Two hundred and thirteen samples (from 175 donors) were only pan-Ig reactive, 8 (from 4 donors) were pan-Ig and IgG reactive, and 43 (from 34 donors) were pan-Ig and IgM reactive. Microneutralization assay showed all negative results. In addition, 213 screened reactive donors were analyzed and did not show obviously temporal or regional tendency, but the distribution of age showed a difference compared with all tested donors. Then we reviewed SARS-CoV-2 antibody results from these donors who donated several times from September 2019 to June 2020, partly tested in a previous published study, no one was found a significant increase in S/CO of antibodies against SARS-CoV-2. Our findings showed no SARS-CoV-2-specific antibodies existing among blood donors in Wuhan, China before 2020, indicating no evidence of transmission of COVID-19 before December 2019 in Wuhan, China.

ObjectiveTo investigate the effect of Xinfeng capsules on immunoinflammatory indicators in patients with rheumatoid arthritis （RA） due to spleen deficiency and dampness exuberance. MethodA total of 102 patients were randomly divided into control group and observation group according to the random number table method， with 51 cases in each group. All patients were treated with methotrexate tablets， while those in the observation group received additional Xinfeng capsules. The course of treatment in both groups was 12 weeks. The 28-joint disease activity score （DAS28）， visual analogue scale （VAS） scores， morning stiffness time， erythrocyte sedimentation rate （ESR）， high-sensitivity C-reactive protein （hs-CRP）， rheumatoid factor （RF）， anti-cyclic citrullinated peptide （anti-CCP） antibody， vascular endothelial growth factor （VEGF）， and serum amyloid A （SAA） of the two groups before and after treatment were compared. The efficacy and incidence of adverse events were compared between the two groups. The Apriori association rule model and random walk model were constructed to evaluate the effect of Xinfeng capsules in improving hs-CRP， ESR， RF， SAA， VEGF， and anti-CCP. ResultThere were no dropouts in this study. There was no statistical difference in the indicators between the two groups before treatment. After 12 weeks of treatment， the total effective rate in the observation group was 90.19% （46/51）， which was higher than 74.51% （38/51） in the control group （χ2＝4.320，P<0.05）. DAS28， VAS score， and morning stiffness time in the observation group were improved compared with those in the control group （P<0.05）. Apriori association rule model results showed that the application of Xinfeng capsules in the observation group had a strong correlation with the reduction of RF， ESR， hs-CRP， SAA， and VEGF. The results of the random walk model showed that the improvement coefficients of hs-CRP， ESR， RF， SAA， and VEGF in the observation group were all better than those of the control group， and the improvement coefficient of anti-CCP in the control group was better than that of the observation group. The improvement degree of hs-CRP， ESR， RF， SAA， and VEGF in the observation group was superior to that of the control group （P<0.05）. The incidence of adverse reactions in the observation group was lower than in the control group （χ2＝4.057，P<0.05）. ConclusionOn the basis of the treatment with methotrexate tablets， Xinfeng capsules can effectively improve the immunoinflammatory level in RA due to spleen deficiency and dampness exuberance and reduce the incidence of adverse reactions.

ResultAfter the treatment， the total effective rate was 90.0% （54/60） in the observation group and 75.0% （45/60） in the control group （χ2=4.675， P<0.05）. After treatment， the OSDI score and TCM syndrome score were lower than those before treatment in both groups （P<0.05）， and lower in the observation group than in the control group （P<0.05）. After treatment， the SIT and BUT were higher （P<0.05） and FL score was lower （P<0.05） than those before treatment in both groups. After treatment， the improvement of the above indicators in the observation group was better than that in the control group （P<0.05）. After treatment， the levels of IL-6 and MMP-9 were lower than those before treatment in both groups （P<0.05）， and lower in the observation group than in the control group （P<0.05）. ConclusionQiju Dihuangtang combined with Chinese medicine fumigation can effectively improve subjective symptoms， promote tear secretion， prolong BUT， enhance corneal epithelial repair， and reduce the levels of tear IL-6 and MMP-9 in the treatment of dry eye.
RESUMEN
【Objective】 To analyze the current situation of direct exemption of clinical blood fess for voluntary blood donors and their family members in Henan Province, in order to improve and fully implement the policy. 【Methods】 According to the policy on blood fees exemption issued by China and Henan Province in 2019,the data of hospitals in 18 prefecture-level cities in Henan from 2020 to 2021 were continuously collected from the system of clinical blood fees exemption,including the way of exemption,the number of people (times) of exemption,exemption amount, the proportion of blood fees exemption and the total exemption rate. The experience gained in the past two years after the implementation of the policy was summarized,and the existing problems and causes were analyzed. 【Results】 The rates of direct exemption of blood fees in Henan Province in 2020 and 2021 were 34.53% (8 709/25 221) and 71.68%(23 587/32 906) (P<0.05) ,respectively. In 2021, the direct exemption rate of blood fees in 18 cities was 6.20% (83/1 370) to 88.50% (1 332/1 505) [ (47.35±41.15)%],and increased month by month from 43.19% (1 183/2 507) in January to 83.15% (2 097/2 522) in August, then remained stable at a similar level to August from September to December, with 83.43% (2 744/3 289) in December as the highest for the year. 【Conclusion】 The implementation of the policy of blood fees exemption showed significant effectiveness, which has effectively promoted the development of voluntary blood donation in Henan. However, there is still room for improving the policy in some cities, which is expected to further increase the direct exemption rate of the city and the whole province.
RESUMEN
Objective: To evaluate the efficacy of surgical treatment of aortic coarctation combined with descending aortic aneurysm in adult patients. Methods: This is a retrospective cohort study. Adult patients with aortic coarctation who were hospitalized in Beijing Anzhen Hospital from January 2015 to April 2019 were enrolled. The aortic coarctation was diagnosed by aortic CT angiography, and the included patients were divided into the combined descending aortic aneurysm group and the uncomplicated descending aortic aneurysm group based on descending aortic diameter. General clinical data and surgery-related data were collected from the included patients, and death and complications were recorded at 30 days after surgery, and upper limb systolic blood pressure was measured in all patients at discharge. Patients were followed up after discharge by outpatient visit or telephone call for their survival and the occurrence of repeat interventions and adverse events, which included death, cerebrovascular events, transient ischemic attack, myocardial infarction, hypertension, postoperative restenosis, and other cardiovascular-related interventions. Results: A total of 107 patients with aortic coarctation aged (34.1±15.2) years were included, and 68 (63.6%) were males. There were 16 cases in the combined descending aortic aneurysm group and 91 cases in the uncomplicated descending aortic aneurysm group. In the combined descending aortic aneurysm group, 6 cases (6/16) underwent artificial vessel bypass, 4 cases (4/16) underwent thoracic aortic artificial vessel replacement, 4 cases (4/16) underwent aortic arch replacement+elephant trunk procedure, and 2 cases (2/16) underwent thoracic endovascular aneurysm repair. There was no statistically significant difference between the two groups in the choice of surgical approach (all P>0.05). In the combined descending aortic aneurysm group at 30 days after surgery, one case underwent re-thoracotomy surgery, one case developed incomplete paraplegia of the lower extremity, and one case died; and the differences in the incidence of endpoint events at 30 days after surgery were similar between the two groups (P>0.05). Systolic blood pressure in the upper extremity at discharge was significantly lower in both groups compared with the preoperative period (in the combined descending aortic aneurysm group: (127.3±16.3) mmHg vs. (140.9±16.3) mmHg, P=0.030, 1 mmHg=0.133 kPa; in the uncomplicated descending aortic aneurysm group: (120.7±13.2) mmHg vs. (151.8±26.3) mmHg, P=0.001). The follow-up time was 3.5 (3.1, 4.4) years. There were no new deaths in the combined descending aortic aneurysm group, no transient ischemic attack, myocardial infarction or re-thoracotomy surgery, and one patient (1/15) suffered cerebral infarction and 10 patients (10/15) were diagnosed with hypertension. The differences in the occurrence of endpoint events during postoperative follow-up were similar between the two groups (P>0.05). Conclusion: In experienced centers, long-term prognosis of patients with aortic coarctation combined with descending aortic aneurysm is satisfactory post surgical intervention.

Periodontitis is an oral infectious disease that occurs in the tooth supporting tissues, which damages the soft and hard tissues of the periodontium and eventually results in tooth mobility and loss. Traditional clinical treatment can effectively control the periodontal infection and inflammation. However, as the therapeutic effect depending on the local condition of periodontal defect and the systemic factors of patients, it's hard to achieve satisfactory and stable periodontal tissue regeneration for damaged periodontal tissues. Recently, as a promising therapeutic strategy in periodontal regeneration, mesenchymal stem cells (MSC) play an important role in modern regenerative medicine. Combined with the clinical translational researches of MSC in periodontal tissue engineering and the research results of our group in the past decade, it is summarized and explained the mechanism of MSC promoting periodontal regeneration, the preclinical and the clinical transformation researches as well as the future application prospects of MSC in periodontal regeneration therapy in this paper.
RESUMEN
OBJECTIVE@#To analyze the clinical phenotype and results of genetic testing in three children with Cornelia de Lange syndrome (CdLS).@*METHODS@#Clinical data of the children and their parents were collected. Peripheral blood samples of the pedigrees were collected for next generation sequencing analysis.@*RESULTS@#The main clinical manifestations of the three children have included growth delay, mental retardation, peculiar facies and other accompanying symptoms. Based on the criteria proposed by the International Diagnostic Consensus, all three children were suspected for CdLS. As revealed by whole exome sequencing, child 1 has harbored NIPBL gene c.5567_5569delGAA insTAT missense variant, child 2 has harbored SMC1A gene c.607A>G missense variant, and child 3 has harbored HDAC8 gene c.628+1G>A splicing variant. All of the variants were de novo in origin.@*CONCLUSION@#All of the children were diagnosed with CdLS due to pathogenic variants of the associated genes, among which the variants of NIPBL and HDAC8 genes were unreported previously. Above finding has enriched the spectrum of pathogenic variants underlying CdLS.

OBJECTIVE@#To explore the genetic etiology of a child with Pitt-Hopkins syndrome.@*METHODS@#A child who had presented at the Medical Genetics Center of Gansu Provincial Maternal and Child Health Care Hospital on February 24, 2021 and his parents were selected as the study subjects. Clinical data of the child was collected. Genomic DNA was extracted from peripheral blood samples of the child and his parents and subjected to trio-whole exome sequencing (trio-WES). Candidate variant was verified by Sanger sequencing. Karyotype analysis was also carried out for the child, and her mother was subjected to ultra-deep sequencing and prenatal diagnosis upon her subsequent pregnancy.@*RESULTS@#The clinical manifestations of the proband included facial dysmorphism, Simian crease, and mental retardation. Genetic testing revealed that he has carried a heterozygous c.1762C>T (p.Arg588Cys) variant of the TCF4 gene, for which both parents had a wild-type. The variant was unreported previously and was rated as likely pathogenic based on the guidelines of the American College of Medical Genetics and Genomics (ACMG). Ultra-deep sequencing indicated that the variant has a proportion of 2.63% in the mother, suggesting the presence of low percentage mosaicism. Prenatal diagnosis of amniotic fluid sample suggested that the fetus did not carry the same variant.@*CONCLUSION@#The heterozygous c.1762C>T variant of the TCF4 gene probably underlay the disease in this child and has derived from the low percentage mosaicism in his mother.
