ABSTRACT

AIM: To assess the efficacy of Quyin Koufuye in different types of psoriasis vulgaris and analyzes the relationship between efficacy and various disease-related factors, as well as its complementary role in biologic therapy. METHODS: This study included a total of 396 patients with psoriasis. Based on the patient history, participants were categorized into the biologics group (n=98), Quyin Koufuye-assisted biologics group (n=62), and Quyin Koufuye monotherapy group (n=236). Patient history data were collected, including gender, duration of illness, disease type, initial site of onset, degree of itching, recurrence status and time, smoking habits, joint pain, family history of psoriasis, nail damage, treatment plan, and PASI/BSA scores. A retrospective analysis was conducted to identify factors influencing the efficacy of Quyin Koufuye and to analyze its combined effects with biologics. RESULTS: Combining Quyin Koufuye with biologics significantly boosted the PASI90 response rate to 72.6% (P=0.014). Responders to PASI50 with Quyin Koufuye experienced longer recurrence intervals (> 6 months) than non-responders (50% vs. 33.6%, P= 0.045). Influencing factors included psoriasis-affected body surface area (OR=0.960, P=0.000), prolonged smoking history (OR=2.10, P=0.046), and psoriasis type (OR=2.47, P=0.015). CONCLUSION: This study underscores the synergy of Quyin Koufuye and biologics in treating psoriasis, particularly for longer recurrence intervals-factors like smoking history, psoriasis type, and affected body surface area impact Quyin Koufuye's efficacy.

ABSTRACT

AIM: To observe the clinical efficacy of Yishen Yanggan Mingmu formula combined with anti-vascular endothelial growth factor(VEGF)in the treatment of wet age-related macular degeneration(wARMD).METHODS: A total of 58 patients(58 eyes)with wARMD who were treated in Ningbo Eye Hospital from September 2020 to November 2022 were collected. They were divided into two groups according to randomized digital table: 29 patients(29 eyes)for the combination group and the other 29 patients(29 eyes)for the injection group. The injection group was only given intravitreal injection of conbercept; the combination group was orally administrated with Yishen Yanggan Mingmu formula combined with intravitreal injection of conbercept. The best corrected visual acuity(BCVA), central macular thickness(CMT)and the improvement of traditional Chinese medicine(TCM)syndromes after 3mo of treatment were observed and the clinical efficacy was evaluated.RESULTS: After 3mo of treatment, the total improved effective rate of the combination group(76%)was higher than the rate of the injection group(66%). After the treatment, the BCVA of the two groups was both higher than that before treatment(P<0.05), the CMT in both groups was lower than that before the treatment(P<0.05), and the improvement of CMT of the combination group was better than the injection group(-155.93±143.79μm vs. -95.36±56.81μm, P<0.05). After 3mo of treatment, each kinds of TCM syndrome in the combination group were significantly improved compared with those syndromes before the treatment(P<0.001). In the injection group, only blurred vision was improved(P<0.05). After the treatment, the scores of dizziness and insomnia, soreness and weakness of waist and knees, paleness and cold limbs, dry eyes and fatigue in the combination group were significantly lower than the injection group(P<0.001).CONCLUSIONS: The Yishen Yanggan Mingmu formula combined with intravitreal anti-VEGF drug injection is effective in the treatment of wARMD.

ABSTRACT

Objective:To investigate the aspiration risk of preventive placement of nasal jejunum nutrition tube in advanced esophageal cancer patients receiving radiotherapy and the influencing factors.Methods:The clinical data of 220 patients with advanced esophageal cancer who received radiotherapy and preventive placement of nasal jejunum nutrition tube feeding from November 2020 to November 2021 in Cancer Hospital, Chinese Academy of Medical Sciences were retrospectively analyzed. The level of aspiration risk was measured according to the standard swallowing function assessment scale (SSA). The questionnaire collected the following data: (1) the general data including gender, age, educational level, history of smoking, history of alcoholism, knowledge of aspiration; (2) the disease factors including tumor staging, tumor site, swallowing function, abdominal distention; (3) the nosocomial factors including history of esophageal cancer surgery, sedation and analgesia treatment, combination of chemotherapy or not, cumulative radiotherapy dose, grade of radiation esophagitis, the position, time and tube feeding method of enteral nutrition. The standard swallowing function of patients was measured and repeated saliva swallowing test (RSST) was used to screen the patients with the difficulty in the esophageal function swallowing. Multiple linear regression was used to analyze the factors affecting aspiration risk.Results:A total of 220 patients with advanced esophageal cancer were enrolled in the investigation. Finally, 70 patients (31.8%) had grade 0 aspiration risk, and SSA score was 19; 23 patients (10.5%) had grade I aspiration risk, and SSA score was (23.4±1.3); 103 patients (46.8%) had grade Ⅱ aspiration risk, and SSA score was (27.5±1.1); 24 patients (10.9%) had grade Ⅲ aspiration risk, and SSA score was (33.2±1.5); 136 patients (61.8%) in total had aspiration risk. There were 32.7% (72/220) patients knowing the knowledge of aspiration. Multifactor analysis showed that esophageal tumor site ( t = -2.869, P = 0.005), cumulative radiotherapy dose ( t = 5.558, P < 0.001), grade of radiation esophagitis ( t = 11.405, P < 0.001), the duration time of enteral nutrition ( t = 4.050, P < 0.001) were independent factors affecting the aspiration risk. Conclusions:The aspiration risk of preventive placement of nasal jejunum nutrition tube in advanced esophageal cancer patients receiving radiotherapy is high, which is related to esophageal tumor site, grade of radiation esophagitis, cumulative radiotherapy dose and the duration time of enteral nutrition.

ABSTRACT

Objective:To observe any effect of ultrashortwave (USW) therapy on inflammatory cytokines and the MAPK pathway of rats with a spinal cord injury.Methods:Seventy-nine Sprague-Dawley rats were randomly divided into a control group ( n=35), an intervention group ( n=35) and a sham group ( n=9). Allen′s method was used to establish a contusion model of SCI in the rats of the control and intervention groups, while the sham group′s spinal tissues were exposed but not stricken. Beginning twenty-four hours after SCI modeling, the intervention group was given 7min of USW therapy daily, five days a week till the day of sacrifice for sampling the target area of spinal cord for tests. Then, motion function was evaluated using Basso, Beattie and Bresnahan (BBB) scoring. One, three and seven days after the SCI modeling, immunofluorescence and western blotting were employed to observe any changes in inflammatory factors and the MAPK pathway in the lesioned area. Results:Fourteen days after the modeling the average BBB score of the intervention group was significantly higher than the control group′s average. Moreover, 7 days after the modeling the average content of the domains containing protein 3 (NLRP3), interleukin-6 (IL-6), IL-6 receptor and tumor necrosis factor-α (TNF-α) in the target area of the spinal cord of sham group showed significantly lower levels than in the other 2 groups. And the levels in the intervention group were significantly lower than in the control group. Seven days after the modeling the number of cells positive for zinc finger protein 36 (TTP) in the lesioned area of the intervention group was significantly greater than among the control group. At the same time the levels of MAPK-activated protein kinase 2 (MK2), phosphorylated-mitogen-activated protein kinase-activated version (p-MK2) and TTP in the control and intervention groups were significantly higher than in the sham group. And there were significant differences between the intervention group and control group in the levels of MK2, p-MK2 and TTP.Conclusion:Ultrashortwave therapy can inhibit inflammation by regulating the MAPK inflammatory pathway, promoting the recovery of motion functions, at least in rats.

ABSTRACT

Ilizarov technique is designed based on the "tension-stress principle". Application of the Ilizarov technique can help form a stable mechanical structure through external fixation. It only creates small wounds, without peeling off the surrounding tissue and periosteum. It connects different types of fixation pins and bone or soft tissue to form a traction force, which continuously stimulates the regeneration of bone and tissue and improves the local blood supply and early functional rehabilitation exercises, forming a complete set of minimally invasive orthopedic treatment systems. Ilizarov technique has achieved good results in fracture healing, deformity correction, tissue repair, osteomyelitis, bone nonunion, bone defect, and bone tumor. This paper will summarize the clinical application and research of the Ilizarov technique in orthopedics and explore the key problems of the Ilizarov technique that need to be solved at present.

ABSTRACT

BACKGROUND@#Previous studies have shown that lymph node metastasis only occurs in some mixed ground-glass nodules (mGGNs) which the pathological results were invasive adenocarcinoma (IAC). However, the presence of lymph node metastasis leads to the upgrading of tumor-node-metastasis (TNM) stage and worse prognosis of the patients, so it is important to perform the necessary evaluation before surgery to guide the operation method of lymph node. The aim of this study was to find suitable clinical and radiological indicators to distinguish whether mGGNs with pathology as IAC is accompanied by lymph node metastasis, and to construct a prediction model for lymph node metastasis.@*METHODS@#From January 2014 to October 2019, the patients with resected IAC appearing as mGGNs in computed tomography (CT) scan were reviewed. All the lesions were divided into two groups (with lymph node metastasis or not) according to their lymph node status. Lasso regression model analysis by applying R software was used to evaluate the relationship between clinical and radiological parameters and lymph node metastasis of mGGNs.@*RESULTS@#A total of 883 mGGNs patients were enroled in this study, among which, 12 (1.36%) showed lymph node metastasis. Lasso regression model analysis of clinical imaging information in mGGNs with lymph node metastasis showed that previous history of malignancy, mean density, mean density of solid components, burr sign and percentage of solid components were informative. Prediction model for lymph node metastasis in mGGNs was developed based on the results of Lasso regression model with area under curve=0.899.@*CONCLUSIONS@#Clinical information combined with CT imaging information can predict lymph node metastasis in mGGNs.

ABSTRACT

Objective: To investigate the clinical features and long-term prognostic factors of diabetic patients with low or intermediate complexity coronary artery disease (CAD) post percutaneous coronary intervention (PCI). Methods: This was a prospective, single-centre observational study. Consecutive diabetic patients with SYNTAX score (SS)≤32 undergoing PCI between January and December 2013 in Fuwai hospital were included in this analysis. The patients were divided into two groups based on SS, namely SS≤22 group and SS 23-32 group. Multivariate Cox regression analysis was performed to identify independent factors related to poor 5-year prognosis. The primary outcomes were cardiac death and recurrent myocardial infarction, the secondary outcomes were all cause death and revascularization. Results: Of the 3 899 patients included in the study, 2 888 were men (74.1%); mean age was 59.4±9.8 years. There were 3 450 patients in the SS≤22 group and 449 patients in the SS 23-32 group. Compared with SS≤22 group, the incidence of revascularization was higher in SS 23-32 group (18.9% (85/449) vs. 15.2% (524/3450), log-rank P=0.019). There was no significant difference in all-cause death, cardiac death and recurrent myocardial infarction between the two groups (log-rank P>0.05). Multivariate Cox regression analysis showed that age (HR=1.05, 95%CI 1.02-1.08, P<0.001), chronic obstructive pulmonary disease (HR=3.12, 95%CI 1.37-7.07, P=0.007) and creatinine clearance rate (CCr)<60 ml/min (HR=3.67, 95%CI 2.05-6.58, P<0.001) were independent risk factors for 5-year cardiac death, while left ventricular ejection fraction (HR=0.94, 95%CI 0.91-0.96, P<0.001) was a protective factor. Previous PCI (HR=2.04, 95%CI 1.38-3.00, P<0.001), blood glucose level≥11.1 mmol/L on admission (HR=2.49, 95%CI 1.32-4.70, P=0.005) and CCr<60 ml/min (HR=1.85, 95%CI 1.14-2.99, P=0.012) were independent risk factors for 5-year recurrent myocardial infarction. The SS of 23-32 was independently associated with risk of revascularization (HR=1.54, 95%CI 1.09-2.16, P=0.014), after adjusting for residual SS. Residual SS was not a risk factor for 5-year prognosis. Conclusions: In diabetic patients with low-or intermediate complexity CAD, SS 23-32 is associated with increased risk of 5-year revascularization; the clinical characteristics of the patients are associated with the long-term mortality and recurrent myocardial infarction, but not related to revascularization.

ABSTRACT

Nonalcoholic steatohepatitis (NASH) is an aggressive form of nonalcoholic fatty liver disease (NAFLD) characterized by steatosis-associated inflammation and liver injury. Without effective treatment or management, NASH can have life-threatening outcomes. Evaluation and identification of NASH patients at risk for adverse outcomes are therefore important. Key issues in screening NASH patients are the assessment of advanced fibrosis, differentiation of NASH from simple steatosis, and monitoring of dynamic changes during follow-up and treatment. Currently, NASH staging and evaluation of the effectiveness for drugs still rely on pathological diagnosis, despite sample error issues and the subjectivity associated with liver biopsy. Optimizing the pathological assessment of liver biopsy samples and developing noninvasive surrogate methods for accessible, accurate, and safe evaluation are therefore critical. Although noninvasive methods including elastography, serum soluble biomarkers, and combined models have been implemented in the last decade, noninvasive diagnostic measurements are not widely applied in clinical practice. More work remains to be done in establishing cost-effective strategies both for screening for at-risk NASH patients and identifying changes in disease severity. In this review, we summarize the current state of noninvasive methods for detecting steatosis, steatohepatitis, and fibrosis in patients with NASH, and discuss noninvasive assessments for screening at-risk patients with a focus on the characteristics that should be monitored at follow-up.

ABSTRACT

OBJECTIVE@#To explore the clinical feature and genetic etiology of a patient with normosmic idiopathic hypogonadotropic hypogonadism (nIHH) due to variant of CHD7 gene.@*METHODS@#A patient who had presented at Anhui Provincial Children's Hospital in October 2022 was selected as the study subject. Clinical data of the patient was collected. The patient and his parents were subjected to trio-whole exome sequencing. Candidate variant was verified by Sanger sequencing and bioinformatic analysis.@*RESULTS@#The patient had featured delayed development of secondary sexual characteristics but normal olfactory function. Genetic testing revealed that he has harbored a c.3052C>T (p.Pro1018Ser) missense variant of the CHD7 gene, for which both of his parents were of the wild type. The variant has not been recorded in the PubMed and HGMD databases. Analysis of amino acid sequences suggested that the variant site is highly conserved, and the variant may affect the stability of protein structure. Based on the guidelines from the American College of Medical Genetics and Genomics, the c.3032C>T variant was classified as a likely pathogenic (PS2+PM2_Supporting+PP2+PP3+PP4).@*CONCLUSION@#The delayed development of secondary sexual characteristics of the patient may be attributed to the c.3052C>T (p.Pro1018Ser) variant of the CHD7 gene. Above finding has expanded the variation spectrum of the CHD7 gene.

ABSTRACT

Petrochemical-derived polyester plastics such as polyethylene terephthalate (PET) and polybutylene adipate terephthalate (PBAT) have been widely used. However, the difficulty to be degraded in nature (PET) or the long biodegradation cycle (PBAT) resulted in serious environmental pollution. In this connection, treating these plastic wastes properly becomes one of the challenges of environment protection. From the perspective of circular economy, biologically depolymerizing the waste of polyester plastics and reusing the depolymerized products is one of the most promising directions. Recent years have seen many reports on polyester plastics degrading organisms and enzymes. Highly efficient degrading enzymes, especially those with better thermal stability, will be conducive to their application. The mesophilic plastic-degrading enzyme Ple629 from the marine microbial metagenome is capable of degrading PET and PBAT at room temperature, but it cannot tolerate high temperature, which hampers its potential application. On the basis of the three-dimensional structure of Ple629 obtained from our previous study, we identified some sites which might be important for its thermal stability by structural comparison and mutation energy analysis. We carried out transformation design, and performed expression, purification and thermal stability determination of the mutants. The melting temperature (Tm) values of mutants V80C and D226C/S281C were increased by 5.2 ℃ and 6.9 ℃, respectively, and the activity of mutant D226C/S281C was also increased by 1.5 times compared with that of the wild-type enzyme. These results provide useful information for future engineering and application of Ple629 in polyester plastic degradation.

ABSTRACT

PET (polyethylene terephthalate) is one of the most important petrochemicals that is widely used in mineral water bottles, food and beverage packaging and textile industry. Because of its stability under environmental conditions, the massive amount of PET wastes caused serious environmental pollution. The use of enzymes to depolymerize PET wastes and upcycling is one of the important directions for plastics pollution control, among which the key is the depolymerization efficiency of PET by PET hydrolase. BHET (bis(hydroxyethyl) terephthalate) is the main intermediate of PET hydrolysis, its accumulation can hinder the degradation efficiency of PET hydrolase significantly, and the synergistic use of PET hydrolase and BHET hydrolase can improve the PET hydrolysis efficiency. In this study, a dienolactone hydrolase from Hydrogenobacter thermophilus which can degrade BHET (HtBHETase) was identified. After heterologous expression in Escherichia coli and purification, the enzymatic properties of HtBHETase were studied. HtBHETase shows higher catalytic activity towards esters with short carbon chains such as p-nitrophenol acetate. The optimal pH and temperature of the reaction with BHET were 5.0 and 55 ℃, respectively. HtBHETase exhibited excellent thermostability, and retained over 80% residual activity after treatment at 80 ℃ for 1 hour. These results indicate that HtBHETase has potential in biological PET depolymerization, which may facilitate the enzymatic degradation of PET.

ABSTRACT

Objective: To explore the key deubiquitinating enzymes that maintain the stemness of liver cancer stem cells and provide new ideas for targeted liver cancer therapy. Methods: The high-throughput CRISPR screening technology was used to screen the deubiquitinating enzymes that maintain the stemness of liver cancer stem cells. RT-qPCR and Western blot were used to analyze gene expression levels. Stemness of liver cancer cells was detected by spheroid-formation and soft agar colony formation assays. Tumor growth in nude mice was detected by subcutaneous tumor-bearing experiments. Bioinformatics and clinical samples were examined for the clinical significance of target genes. Results: MINDY1 was highly expressed in liver cancer stem cells. The expression of stem markers, the self-renewal ability of cells, and the growth of transplanted tumors were significantly reduced and inhibited after knocking out MINDY1, and its mechanism of action may be related to the regulation of the Wnt signaling pathway. The expression level of MINDY1 was higher in liver cancer tissues than that in adjacent tumors, which was closely related to tumor progression, and its high expression was an independent risk factor for a poor prognosis of liver cancer. Conclusion: The deubiquitinating enzyme MINDY1 promotes stemness in liver cancer cells and is one of the independent predictors of poor prognosis in liver cancer.

ABSTRACT

Objective: To explore and compare the effect of standard or prolonged dual antiplatelet therapy (DAPT) on the long-term prognosis of elderly patients with coronary heart disease complicated with diabetes mellitus after drug-eluting stent (DES) implantation. Methods: Consecutive patients with diabetes mellitus, ≥65 years old, underwent DES implantation, and had no adverse events within 1 year after operation underwent percutaneous coronary intervention (PCI) from January to December 2013 in Fuwai Hospital were enrolled in this prospective cohort study. These patients were divided into three groups according to DAPT duration: standard DAPT duration group (11 ≤ DAPT duration≤ 13 months) and prolonged DAPT duration group (13<DAPT duration≤ 24 months; DAPT duration>24 months). All the patients were followed up at 1, 6 months, 1, 2 and 5 years in order to collect the incidence of major adverse cardiovascular and cerebrovascular events (MACCE), and type 2 to 5 bleeding events defined by the Federation of Bleeding Academic Research (BARC). MACCE were consisted of all cause death, myocardial infarction, target vessel revascularization or stroke. The incidence of clinical adverse events were compared among 3 different DAPT duration groups, and Cox regression model were used to analyze the effect of different DAPT duration on 5-year long-term prognosis. Results: A total of 1 562 patients were enrolled, aged (70.8±4.5) years, with 398 female (25.5%). There were 467 cases in standard DAPT duration group, 684 cases in 13<DAPT duration≤ 24 months group and 411 cases in DAPT duration>24 months group. The patients in standard DAPT duration group and the prolonged DAPT duration groups accounted for 29.9% (467/1 562) and 70.1% (1 095/1 562), respectively. The 5-year follow-up results showed that the incidence of all-cause death in 13<DAPT duration≤ 24 months group (4.8%(33/684) vs. 8.6%(40/467),P=0.011) and DAPT duration>24 month group(4.1%(17/411) vs. 8.6%(40/467),P=0.008) were significantly lower than in standard DAPT group. The incidence of myocardial infarction in 13<DAPT duration≤ 24 months group was lower than in standard DAPT duration group (1.9%(13/684) vs. 5.1%(24/467),P=0.002). The incidence of MACCE in 13<DAPT duration≤ 24 months group was the lowest (standard DAPT duration group, 13<DAPT duration≤ 24 months group and DAPT duration>24 month group were 19.3% (90/467), 12.3% (84/684), 20.2% (83/411), respectively, P<0.001). There was no significant difference in the incidence of stroke and bleeding events among the three groups (all P>0.05). Multivariate Cox analysis showed that compared with the standard DAPT group, prolonged DAPT to 13-24 months was negatively correlated with MACCE (HR=0.601, 95%CI 0.446-0.811, P=0.001), all-cause death (HR=0.568, 95%CI 0.357-0.903, P=0.017) and myocardial infarction (HR=0.353, 95%CI 0.179-0.695, P=0.003). DAPT>24 months was negatively correlated with all-cause death (HR=0.687, 95%CI 0.516-0.913, P=0.010) and positively correlated with revascularization (HR=1.404, 95%CI 1.116-1.765, P=0.004). There was no correlation between prolonged DAPT and bleeding events. Conclusions: For elderly patients with coronary heart disease complicated with diabetes mellitus underwent DES implantation, and had no MACCE and bleeding events within 1 year after operation, appropriately prolonging of the DAPT duration is related to the reduction of the risk of cardiovascular adverse events. Patients may benefit the most from the DAPT between 13 to 24 months. In addition, prolonging DAPT duration does not increase the incidence of bleeding events in this patient cohort.

ABSTRACT

This paper reported the genetic analysis of a pedigree in which three affected fetuses with short limbs were revealed by first-trimester ultrasonography in three consecutive pregnancies. Tissues of the second aborted fetus were collected and analyzed by chromosome karyotype analysis and whole exome sequencing. The results indicated compound heterozygous mutations of EX64-EX83 Del and c.8190G>T in the DYNC2H1 gene. Real-time fluorescence quantitative polymerase chain reaction and Sanger sequencing further confirmed that the two variants were inherited from the father and the mother with normal phenotypes, respectively. EX64-EX83 Del was a likely pathogenic variant and c.8190G>T was a variant of uncertain significance. Based on the above results and the medical history, it was highly suspected that the fetus had autosomal recessive short rib polydactyly syndrome type Ⅲ caused by compound heterozygous variants. Real-time fluorescent quantitative polymerase chain reaction and Sanger sequencing results of the third aborted fetus were consistent with the second fetus. Given the same phenotypes of fetuses in the second and third pregnancy, it was strongly suggested that the heterozygous variations of EX64-EX83 Del and c.8190G>T in the DYNC2H1 gene were the pathogenic variants in this pedigree.

ABSTRACT

Objective:To explore the effect of dietary intake before fasting on the physiological distribution of 18F-FDG PET/CT, and to improve the 18F-FDG PET/CT image quality. Methods:From August 2019 to May 2020, questionnaire of dietary intake before fasting of 118 patients (73 males, 45 females; age (58.4±13.4) years) who performed PET/CT imaging in Zhongshan Hospital, Fudan University were retrospectively analyzed. The total dietary energy intake, the nutrient intake and energy supply ratio of the three energy source nutrients, the type of raw materials and the texture of diet were included. The SUV max and SUV mean of the liver, mediastinal blood pool and hip muscles were measured. Single-factor and multi-factors linear regression analyses were used to analyze data. Results:The fasting blood glucose of 118 subjects was (5.36±1.01) mmol/L. The texture of diet before fasting were general diet, semiliquid diet and liquid diet, which were 42 (35.59%), 72 (61.02%) and 4 (3.39%) subjects, respectively. The energy supply ratios of carbohydrate, protein and fat were (55.46±18.27)%, (16.70±7.38)% and (27.72±14.53)%, respectively. The results of multi-factors regression analysis indicted that protein energy ratio was an independent factor influencing SUV max ( β=0.005, P=0.031) and SUV mean ( β=0.003, P=0.042) of the hip muscles, and the texture of diet was an independent factor influencing SUV max ( β=0.126, P=0.030) and SUV mean ( β=0.197, P=0.002) of mediastinal blood pool. Conclusions:The dietary intake before fasting has significant effect on the imaging quality of 18F-FDG. The protein energy ratio is an independent factor influencing SUV max and SUV mean of the hip muscles. The texture of diet is an independent factor influencing SUV max and SUV mean of mediastinal blood pool.

ABSTRACT

Objective:To evaluate the effect of noninvasive prenatal testing (NIPT) as first-line screening in fetal chromosome aneuploidy screening practice, and to provide evidence for the prevention and control strategy of birth defects.Methods:Since July 2019, Hebei province had carried out the NIPT project providing first-line screening for eligible pregnant women in the area (except for those who were not applicable). Pregnant women with high risk received genetic counseling, prenatal diagnosis and intervention guidance. Low risk and false-positive ones received continuous detection and moved to prenatal diagnosis center for counseling and diagnosis if abnormities were discovered. All pregnant women were followed up to learn about pregnancy outcomes and newborn health status. Detection results and clinical data of pregnant women participating the NIPT project from July 2019 to July 2020 were collected. The detection results and effect of NIPT were analyzed.Results:(1) Basic information of the screened population: A total of 424 330 pregnant women were screened, and 423 596 were successfully detected, with a success rate of 99.83% (423 596/424 330). The age of pregnant women was (28.8±4.5) years old; the gestational age of screening was (16.6±2.3) weeks; the proportion of advanced-age pregnant women (≥35 years old) was 10.18% (43 132/423 596); in vitro fertilization-embryo transfer (IVF-ET) rate was 1.58% (6 713/423 596); the twin rate was 1.38% (5 849/423 596); the proportion of primipara was 34.23% (144 977/423 596). (2) Screening results and detection performance: totally, 325, 73 and 20 pregnant women were diagnosed with trisomy 21, 18 and 13; the sensitivity were 99.39%, 100.00% and 100.00%; the specificity were 99.98%, 99.99% and 99.98%; the positive predictive value were 75.76%, 68.87% and 21.51%, respectively. Besides, 249 190 pregnant women were received supplementary reports as well, and 255, 10 and 9 were confirmed for sex chromosome aneuploidy, other autosomal aneuploidy and deletion/duplication syndrome; the positive predictive value were 37.78%, 6.06% and 32.14%, respectively. The sensitivity of NIPT for target trisomy (trisomy 21, 18 and 13) screening in advanced-age, IVF-ET and twin pregnant women were 99.29%, 100.00% and 90.00%, respectively; the specificity were 99.93% for all; the positive predictive value were 82.25%, 61.54% and 69.23%, respectively.Conclusions:NIPT has a significant effect and good performance in the first-line screening of fetal chromosome aneuploidy in the whole population, which might provide reference for the improvement of birth defect prevention and control strategy.

ABSTRACT

Objective:To investigate the role of miR-146a in the pathogenesis of systemic juvenile idiopathic arthritis (sJIA) and its clinical significance.Methods:This article is a prospective clinical cohort study.Twenty-six patients with sJIA (14 cases of initial active group and 12 cases of stable group), 15 patients with multijoint juvenile idiopathic arthritis (JIA) and 15 patients with oligojoint JIA diagnosed in the Department of Rheumatology and Immunology of Anhui Provincial Children′s Hospital from June 2018 to December 2020 were enrolled.Twenty healthy controls from the out-patient clinic were also recruited.The expression level of miR-146a in peripheral blood mononuclear cells (PBMCs) of research objects was detected by real-time fluorescence quantitative polymerase reaction (qPCR), and the serum levels of interleukin (IL) - 6, tumor necrosis factor (TNF) - α and IL-1β in sJIA patients and healthy controls were detected by enzyme-linked immunosorbent assay.The expression levels of miR-146a in PBMCs and cytokines among different groups were compared by analysis of variance. Pearson correlation analysis was used to analyze the correlation of the relative expression level of miR-146a in PBMCs with clinical inflammatory indexes and serum cytokines in sJIA patients. Results:(1) The expression level of miR-146a in PBMCs of early sJIA patients was significantly higher than that in the multijoint JIA group and oligojoint JIA group (8.77±3.15 vs.4.40±1.59, 2.55±1.15, t=6.27, 14.23; all P<0.05). The expression level of miR-146a in PBMCs of sJIA active patients was significantly higher than that in sJIA stable patients (8.77±3.15 vs.3.63±1.37, t=10.27, P<0.05). There was no significant difference in the expression level of miR-146a between the sJIA stable group and healthy control group ( P>0.05). (2) The expression levels of IL-1β, IL-6 and TNF-α were significantly higher in sJIA active patients group than those in sJIA stable group[(58.56±17.47) ng/L vs.(26.32±10.54) ng/L, (73.72±11.16) ng/L vs.(23.20±9.12) ng/L, (70.93±19.97) ng/L vs.(24.25±9.49) ng/L, all P<0.05]. There was no significant difference in the expression levels of IL-1β, IL-6 and TNF-α between the sJIA stable group and healthy control group(all P>0.05). (3)The expression of miR-146a in PBMCs of sJIA patients was positively correlated with serum ferritin levels, platelets, erythrocyte sedimentation rates, C-reactive proteins, IL-1β, IL-6 and TNF-α( r=0.542, 0.433, 0.329, 0.306, 0.333, 0.342, 0.319, all P<0.05). Conclusions:miR-146a may be involved in the inflammatory process of sJIA disease.miR-146a can well distinguish sJIA from multijoint JIA and oligojoint JIA.TNF-α, IL-1β and IL-6 are involved in sJIA inflammatory responses.

ABSTRACT

Objective:To examine the feasibility and safety of endoscopic subcutaneous mastectomy and immediate reconstruction via a small skin incision approach without gas and mesh for early breast carcinomas.Methods:We analyzed 7 patients diagnosed with breast cancer who underwent an endoscopic subcutaneous mastectomy and immediate reconstruction from Jun. to Nov. 2021 using a gasless and meshless small skin incision approach at the Department of Thyroid and Breast Surgery, the First Affiliated Hospital of USTC. Mean age was 44.9 (29-63) years. Clinical stage, postoperative complications and other data of patients were collected. Patients were required to fill in BREAST-Q scale anonymously before and during postoperative follow-up. The difference was considered significant for P < 0.05. Results:The tumors were all unilateral and solitary lesions, with a mean diameter of 1.74 (0-5) cm. The average distance of mass from the nipple on imaging was 2.11cm (range 0 to 4) . Postoperative pathological clinical stage,1 patient was in Tis, 3 patients were in stage I, 2 patients were in stage II and a pathological complete response was achieved in one patient (ypT0pN0cM0 CR) . The mean operative time was 245.3 (195-316) min, the mean intraoperative bleeding volume was 37.1ml, the mean postoperative hospital stay was 5.1 d, and the median follow-up time was 8.8 (6-11.2) months. All the 7 patients had incision healing at the first stage, and no complications such as infection, incision complications, capsular contracture, nipple-areola complex or skin flap necrosis, removal or displacement of breast implant occurred. No local recurrence or metastasis was detected during the follow-up period. Compared with preoperative, the scores of postoperative psychosocial status, chest wall status were lower ( P<0.05) , but still ideal, while breast satisfaction and sexual satisfaction scores were not significantly different from preoperative baseline ( P>0.05) . Conclusion:This study indicates that endoscope-assisted breast reconstruction with gasless and meshless is a safe and feasible surgical intervention method for early breast cancer, with good cosmetic effects, and can be promoted as a new type of breast reconstruction.
