ABSTRACT

Objective: To explore the pathogenesis and risk factors of gallstone formation. Methods: The findings of hepatobiliary ultrasound and related data were collected from healthy subjects who underwent a physical examination at Xuanwu Hospital of Capital Medical University from January 2012 to December 2021. A total of 98 344 healthy subjects were included in the study,including 48 241 males and 50 103 females,with a ratio of 1∶1.03,aged (42.0±15.6)years(range:14 to 97 years). The gender,age,body mass index,waist circumference,systolic pressure,diastolic pressure,ALT,AST,total bilirubin,fasting blood glucose,triglyceride,total cholesterol,low-density lipoprotein,high-density lipoprotein were collected.Healthy subjects were required to sit for at least 10 minutes before blood pressure was measured.Rresults of fasting venous blood were collected after 8 to 12 hours on an empty stomach.According to the presence of gallstones by ultrasound results, healthy subjects were divided into study group and control group. Data were analyzed by rank-sum tests and χ2 test, and risk factors for gallstone formation were explored by Logistic regression analysis. Results: The incidence of gallstones in this group was 5.42%(5 333/98 344). Among them,the incidence of gallstones in people aged 60 years and above was significantly higher than that in people under 60 years old(15.31%(2 348/15 334) vs. 3.60%(2 985/83 010), χ2=3 473.46,P<0.05).The healthy subjects were divided by age for every 10 years,and the results showed that the incidence of gallstones increased with age. The incidence of gallstones in females was 5.68%(2 844/50 103),greater than 5.16%(2 489/48 241) in males(χ2=11.81,P<0.05). Among them,1 478 cases underwent gallbladder surgical resection due to gallstones,and the operation rate was 27.71%. The operation rate reached the peak between 60 and <70 years old,and decreased after 70 years old. The results of the multivariate analysis showed that,female(OR=1.38, P<0.01),age(OR=1.58, P<0.01),body mass index≥24 kg/m2(OR=1.31, P<0.01),waist circumference≥85 cm(OR=1.24, P<0.01),fasting blood glucose>6.1 mmol/L(OR=1.18,P<0.01),total cholesterol≥5.18 mmol/L(OR=0.87, P=0.019),low-density lipoprotein≥3.37 mmol/L(OR=1.15,P=0.001) were the risk factors for gallstone formation;high-density lipoprotein≥1.55 mmol/L(OR=0.87, P<0.01) was a protective factor for gallstone formation. Conclusions: The incidence of gallstones increases with age in male and female. Gender,age,body mass index,waist circumferenc,fasting blood glucose,total cholesterol,LDL,and HDL are related factors with gallstone formation.

ABSTRACT

Objective:To explore the interleukin-31 protein expression in the hypertrophic scar of incision tissue after surgery and its underlying pathological impact.Methods:From February 2022 to February 2023, three HS patients scar tissue (HS) and their normal skin tissue (Control, NS) were obtained. Two patients were female and one patient was male. The tissues were fixed in 4% formalin and embedded in paraffin. Haematoxylin-eosin (HE) stain and immunohistochemical stain were used to evaluate the epidermal thickness, myofibroblasts of dermis and the expression level of IL-31 between HS and NS.Results:The epidermis thickness was (303.88±46.03) μm in HS group, while (133.02±17.40) μm in NS group ( t=12.60, P<0.001). The expression level of IL-31 protein was measured by IRS score and positive cell density. The IRS score was 9.89±2.03 of the basal layer in HS group and was 4.33±1.66 of the basal layer in NS group. The positive cell density was 786 343.83±159 627.97 of the basal layer in HS group ( P<0.001) and was 555 457.61±128 097.21 of the basal layer in NS group ( P=0.014). In the dermis layer, the IRS score was 7.11±1.05 in HS group and was 4.33±0.71 in NS group, the positive cell density was 156 760.97±26 046.10 in HS group ( P<0.001) and was 49 576.01±52 369.33 in NS group ( P<0.001). In the dermis layer, the count of myofibroblasts was 120.44±15.75 in HS group while was 27.39±14.89 in NS group ( t=23.79, P<0.001). Conclusions:Our study demonstrates that both myofibroblast count and IL-31 protein expression level are notably increased in HS patients. The expression of IL-31 protein is prominent in the cytoplasm of myofibroblasts, basal cells, macrophages and mast cells which could implicate that IL-31 may be a potential therapeutic target to enhance the resolution of HS.

ABSTRACT

Objective:To investigate epidemiological and clinical characteristics of botulism, and the adverse events among those received botulinum antitoxin treatment.Methods:Patients with discharge diagnosis as botulism in the Second Affiliated Hospital of Xinjiang Medical University were enrolled between 2017 and 2021. The epidemiological and clinical characteristics were evaluated. Infection and mechanical ventilation as in-hospital outcomes according to baseline characteristics were analyzed. Patients with and without the interested outcomes were compared. The adverse outcomes among those received botulinum antitoxin treatment were investigated. Those with and without the adverse outcomes were also compared.Results:Sixty-seven cases of botulism were enrolled, and most cases got sick between January and March (32/67, 47.8%); among them 62 cases were Han ethnicity (92.5%); prevalence was highest in Aksu region (15/67, 22.4%); commonly seen symptoms and signs included fatigue (58/67, 86.6%), dysphagia (48/67, 71.6%), dizziness (42/67, 62.7%), ptosis (42/67, 62.7%), blurred vision (41/67, 61.2%), and limb weakness (35/67, 52.2%). Compared with patients without in-hospital infection ( n=52), patients with in-hospital infection ( n=15) were more likely to have severe botulism (0/52 vs 5/15, χ 2=19.79, P<0.001), diplopia (16/52, 30.8% vs 11/15, χ 2=8.77, P=0.003), dysarthria (17/52, 32.7% vs 11/15, χ 2=7.91, P=0.005), consciousness disorder (1/52, 1.9% vs 4/15, χ 2=10.32, P=0.008). Compared with patients without mechanical ventilation (62/67, 92.5%), patients with mechanical ventilation (5/67, 7.5%) were more likely to have severe botulism (5/5 vs 0/62, χ 2=41.17, P<0.001), and consciousness disorder (4/5 vs 1/62, 1.6%, χ 2=29.58, P<0.001). Among 67 cases of botulism, 19 cases (28.4%) had adverse events after receiving antitoxin treatment, with an average of 6.5 days from the antitoxin treatment beginning to the adverse event onset; among the 19 cases, 18 cases (94.7%) had rash. Age, sex, and severity did not differ between the groups with ( n=19) and without adverse events ( n=48) after receiving antitoxin treatment. Conclusions:Fatigue, dysphagia, dizziness, ptosis were the most frequent symptoms and signs in the botulism in Xinjiang Uygur Autonomous Region, China. Infection was a commonly seen complication of botulism, and proactive prevention and close monitoring were needed. Adverse events after receiving antitoxin were prevalent, and might not be associated with age, sex, and severity of botulism.

ABSTRACT

Gallstone is a common and frequent disease and frequent incidence, secondary infection and cancer seriously affect the health of patients. Academic organizations in different regions have issued multiple guidelines and consensus to promote the normative diagnosis and treatment of gallstones. However, in clinical practice, most symptomatic gallstones are treated, while the formation and prevention process of gallstones are ignored, making the concept of treating without a disease has not been strengthened.This article reviews the risk factors and mechanisms of gallstone formation, and points out the importance of effective prevention during stone formation. In the stage of gallstone formation, the high risk factors of stone formation can be analyzed through two aspects of injury factors and protective factors, and the high risk groups of stone formation can be screened out. According to the pathophysiological progression of gallstones, personalized prevention and follow-up strategies can be developed for the stone formation stage of gallstones.

ABSTRACT

Cholestatic liver disease is a common disease that causes bile flow dysfunction due to various reasons. The etiology of cholestatic liver disease is complexed, and therapeutic drugs are extremely limited. To date, ursodeoxycholic acid is the only FDA-approved drug for treating primary biliary cirrhosis, whereas its efficacy is limited to early stage of the disease, therefore novel drugs are urgently needed. Nuclear receptors become therapeutic hotspot target in cholestasis since these receptors play a key role in regulating bile acid homeostasis. Peroxisome proliferator-activated receptor (PPAR) is an important nuclear receptor involved in regulating multiple mechanisms of cholestasis in vivo. It can improve intrahepatic cholestasis by inhibiting bile acid synthesis, reducing bile acid toxicity, affecting the expression of bile acid metabolic enzymes and transporters, and can play an anti-inflammatory, anti-oxidation and anti-fibrosis role. A number of studies have shown that PPAR agonists represented by fibrates alone or in combination can improve liver function indexes, inflammatory factors and fibrosis markers in patients with cholestasis. This review analyzes and summarizes the lastest advances in the molecular mechanism of PPAR as a therapeutic target for cholestasis and drug treatment in development or have been used in clinical.

ABSTRACT

Objective To understand the quality status of salt iodine monitoring results at the county level and checking results at the city level from 2017 to 2021 in Suzhou,and to provide a scientific basis for the development of iodine deficiency disease(IDD)prevention and control strategies and measures.  Methods During the past five years, Suzhou CDC randomly selected 15 samples of 300 monitored salt samples from each county/district CDC each year for spot checks. The data were processed by comparative analysis of relative error and grouped data t test.  Results In the conformity of iodized salt and non-iodized salt, the sample monitoring results of some counties/districts were non-iodized salt, while the city-level test results were iodized salt. In the conformity of iodized salt and seaweed iodized salt (or enhanced salt), the sample monitoring results of county/district level were iodized salt, while the test results at the city level were seaweed iodized salt (or enhanced salt). The non-conformity was relatively concentrated in some county/district laboratories, and the total amount of non-conformity tended to increase year by year. The total number of samples with relative error of >20% between the county/district and city-level results was the least in 2021, with 6, and the most in 2018, with 25. The number of samples with relative error of >30% between the county/district and city-level results was the least in 2017 being 0, while there were 12 samples in 2018, fluctuating within a small range in the past three years. The t-test results of grouped data showed that the average value of the checking results at the city level was generally higher than the monitoring results at the county level. There were 21 pairs of data with no statistical significance (P>0.05) and 29 pairs of data with statistical significance (P<0.05) between the results at the county/district level and at the city level. Among them, there were 7 counties/districts whose sample monitoring results were not significantly different from the city-level test results in 2020, while there were 9 counties/districts whose monitoring results were statistically different from the city-level test results in 2021.  Conclusion  The data analysis results show that the monitoring data of iodized salt in Suzhou is basically reliable and accurate, but there still exist some problems. Therefore, in the future work it is necessary to strengthen the monitoring system of IDD, increase training efforts, continuously monitor and check the quality of iodized salt to provide a scientific basis for effective prevention and control of IDD.

ABSTRACT

Objective To investigate the prevalence and influencing factors of thyroid nodules in children aged 8-10 years in Suzhou , and to provide a scientific basis for the rational prevention and treatment of iodine deficiency disorders (IDD). Methods PPS sampling method was used in this study. Questionnaire survey, physical examination and thyroid B-ultrasound examination were conducted on students aged 8-10 years. Salt samples and urine samples were collected for laboratory detection of the salt iodine and urinary iodine. Univariate and multivariate logistic regression models were used to analyze the risk factors related to thyroid nodules. Results A total of 2 048 children aged 8-10 years were included in the present survey, and the prevalence of thyroid nodules was 23.34% (478/2 048). The prevalence of nodules in boys was 20.98% (218/1 039), and the prevalence of nodules in girls was 25.77% (260/1 009). Multivariate analysis showed that gender (OR=1.338, P=0.006), height (OR=1.993, P=0.001), frequency of iodine-rich food intake (OR=0.862, P=0.048) and nutritional supplements (OR=1.469, P=0.008) were correlated with the prevalence of thyroid nodules. Conclusion The prevalence rate of thyroid nodules in children aged 8-10 years old in Suzhou is 23.34%. Female gender, higher height, regular intake of iodine-rich foods and dietary supplements are statistically associated with the prevalence of thyroid nodules, which may be risk factors for the prevalence of thyroid nodules , but further research is needed to confirm.

ABSTRACT

Owing to the advancement in pharmaceutical technology, traditional Chinese medicine industry has seen rapid development. Preferring conventional manufacturing mode, pharmaceutical enterprises of traditional Chinese medicine have no effective process detection tools and process control methods. As a result, the quality of the final products mainly depends on testing and the quality is inconsistent in the same batch. Process analytical technology(PAT) for traditional Chinese medicine manufacturing, as one of the key advanced manufacturing techniques, can break through the bottleneck in quality control of medicine manufacturing, thus improving the production efficiency and product quality and reducing the material and energy consumption. It is applicable to the process control and real-time release of advanced manufacturing modes such as intelligent manufacturing and continuous manufacturing. This paper summarized the general idea of PAT for traditional Chinese medicine manufacturing. Through the analysis of the characteristics and status quo of the technology, we summed up the methodology for the continuous application and improvement of PAT during the whole life-cycle of traditional Chinese medicine. The five key procedures(process understanding, process detection, process modeling, process control, and continuous improvement) were summarized, and the application was reviewed. Finally, we proposed suggestions for the technical and regulatory challenges in implementing PAT in traditional Chinese medicine industry. This paper aims to provide a reference for development and application of PAT in advanced manufacturing, intelligent manufacturing, and continuous manufacturing of traditional Chinese medicine industry.

ABSTRACT

Objective:To analyze skin manifestations of pediatric inflammatory bowel disease (IBD) .Methods:Children with IBD were collected from pediatric wards in Peking University Third Hospital from January 2010 to January 2022, and their skin manifestations were retrospectively analyzed.Results:A total of 50 children with IBD were included, including 27 with Crohn′s disease and 23 with ulcerative colitis. Twenty-five (50%) patients had skin manifestations, including specific skin manifestations in 11 (22%) and relevant skin manifestations in 11 (22%) . Specific skin manifestations included cutaneous perianal Crohn′s disease in 2 cases, and anal fistula and/or perianal abscess in 9 cases; relevant skin manifestations included erythema nodosum in 5 cases, aphthous stomatitis in 3 cases, psoriasis in 1 case, polyarteritis nodosa in 1 case, and Henoch-Sch?nlein purpura in 1 case. Compared with the ulcerative colitis group, the Crohn′s disease group was more prone to suffer from specific skin manifestations and relevant skin manifestations, and there were significant differences in the prevalence of specific and relevant skin manifestations between the two groups (both P < 0.05) . Of the 27 children with Crohn′s disease, 19 (70%) had one or more skin manifestations, 2 of whom successively presented with 4 different skin manifestations. One child with Crohn′s disease and 1 with ulcerative colitis had 3 different skin manifestations in different periods. The fecal calprotectin level was elevated in all children with skin manifestations, and in 12 (48%) children without skin manifestations. The skin lesions of 5 children were improved or subsided after dose adjustment (1 case) or switch (4 cases) of biological agents. Conclusions:Half of the children with IBD have skin manifestations, and children with Crohn′s disease are more prone to have specific and relevant skin manifestations. Different skin manifestations could be observed in the same child in different periods. Multidisciplinary teamwork is conducive to the overall control of this disease.

ABSTRACT

OBJECTIVES@#Obstructive sleep apnea hypopnea syndrome (OSAHS) is a common disease that seriously affects health. Continuous positive airway pressure (CPAP) therapy is the preferred treatment for moderate-to-severe OSAHS patients. However, poor adherence to CPAP is a major obstacle in the treatment of OSAHS. Information-motivation-behavioral (IMB) skills, as a kind of mature technology to change the behavior, has been used in various health areas to improve treatment adherence. This study aims to explore the effects of the IMB skills intervention on CPAP adherence in OSAHS patients.@*METHODS@#Patients who were primary diagnosed with moderate-to-severe OSAHS were randomly divided into the IMB group (n=62) and the control group (n=58). The patients in the IMB group received CPAP therapy and the IMB skills intervention for 4 weeks. The patients in the control group received CPAP therapy and a usual health care provided by a registered nurse. We collected the baseline data of the general information, including age, sex, body mass index (BMI), the Epworth Sleepiness Scale (ESS) score, the Hospital Anxiety and Depression Scale (HADS) score, and indicators about disease severity [apnea-hypopnea index (AHI), percentage of time with arterial oxygen saturation SaO2<90% (T90), average SaO2, lowest SaO2, arousal index]. After CPAP titration, we collected CPAP therapy-relevant parameters (optimal pressure, maximum leakage, average leakage, 95% leakage, and residual AHI), score of satisfaction and acceptance of CPAP therapy, and score of willingness to continue CPAP therapy. After 4 weeks treatment, we collected the ESS score, HADS score, CPAP therapy-relevant parameters, effective CPAP therapy time per night, CPAP therapy days within 4 weeks, CPAP adherence rate, score of satisfaction and acceptance of CPAP therapy, and score of willingness to continue CPAP therapy. Visual analog scale (VAS) of 0-5 was used to evaluate the satisfaction and acceptance of IMB intervention measures in the IMB group.@*RESULTS@#There were no significant differences in the baseline level of demographic parameters, ESS score, HADS score, disease severity, and CPAP therapy related parameters between the IMB group and the control group (all P>0.05). There were no significant differences in score of willingness to continue CPAP therapy, as well as score of satisfaction and acceptance of CPAP therapy after CPAP titration between the IMB group and the control group (both P>0.05). After 4 weeks treatment, the ESS score, HADS score, maximum leakage, average leakage, and 95% leakage of the IMB group were significantly decreased, while the score of satisfaction and acceptance of CPAP therapy and willingness to continue CPAP therapy of the IMB group were significantly increased (all P<0.05); while the above indexes in the control group were not different before and after 4 weeks treatment (all P<0.05). Compared with the control group, the ESS score, HADS score, maximum leakage, average leakage, and 95% leakage of the IMB group after 4 weeks treatment were significantly lower (all P<0.05); the effective CPAP therapy time, CPAP therapy days within 4 weeks, score of satisfaction and acceptance of CPAP therapy, score of willingness to continue CPAP therapy of the IMB group were significantly higher (all P<0.05). The rate of CPAP therapy adherence in 4 weeks of the IMB group was significantly higher than that of the control group (90.3% vs 62.1%, P<0.05). The VAS of overall satisfaction with IMB skills intervention measures was 4.46±0.35.@*CONCLUSIONS@#IMB skills intervention measures can effectively improve the adherence of CPAP therapy in OSAHS patients, and is suitable for clinical promotion.

ABSTRACT

Physical attributes of Chinese herbal extracts are determined by their chemical components, and the physical and chemical attributes jointly affect the preparation process performance and the final product quality. Therefore, in order to improve the quality control of Chinese herbal extracts, we should comprehensively study the batch-to-batch consistency of physical and chemical attributes as well as the correlations between them. This paper first explored the physical attributes affecting the preparation process performance of the compound Danshen extract and developed a method for characterizing the texture attributes. With such main chemical components as water, phenolic acids, saponins, and saccharides and texture, rheology, and other physical attributes taken into consideration, the batch-to-batch quality fluctuation of products from different production lines and time was analyzed by principal components analysis(PCA). Finally, the correlation and partial least squares(PLS) analysis was conducted, and the regression equation was established. The fitting result of the PLS model for dynamic viscosity was satisfying(R~2Y=0.857, Q~2=0.793), suggesting that the chemical components could be adjusted by the component transfer rate in the extraction process, the impurity removal rate in the alcohol precipitation process, and the water retention rate of the concentration process to meet the control of the extract dynamic viscosity. This study clarified the correlations between physical and chemical attributes of the compound Danshen extract and established a method for controlling its physical attributes based on process regulation, which would provide reference for improving the quality control of Chinese herbal extracts.

ABSTRACT

To analyze a suspected case of Clostridium botulinum food poisoning in Bayingolin Mongolian Autonomous Prefecture, Xinjiang and to help validating the diagnosis and providing technical support for clinical treatment. The basic information and clinical manifestations of food poisoning cases were investigated by using the epidemiological method of food safety accidents. The botulinum toxin genes in the samples were detected by real-time PCR and inoculation of KM mouse. The enriched bacteria were further purified and validated. PFGE and cluster analysis were performed on five isolates. Clostridium botulinum type A was detected in two homemade fermented bean samples and stool lavage fluid samples of three patients from enriched samples by toxin test and real-time PCR, and were further validated after isolation of Clostridium botulinum. PFGE showed 100% homology among five isolates. Five isolates of bacteria isolated from the stool lavage fluid of three patients and two homemade fermented bean curd were identified as the same source through PFGE. The cause of this food poisoning cases is food pollution of Clostridium botulinum type A.

ABSTRACT

Objective To discuss 7Be and a 77.2 keV full-energy peak with short half-life found in the water sample from the 3D water phantom of a proton therapy system. Methods We measured the water sample from the 3D water phantom of a proton therapy system according to Determination of Radionuclides in Water by Gamma Spectrometry (GB/T 16140—2018). Results The activity concentration of 7Be in the water sample was 1.30 × 101 Bq·L−1 on December 24, 2018; 4.3 × 101 Bq·L−1 on March 22, 2019; and 1.41 × 101 Bq·L−1 at the time of sampling on December 19, 2018. On December 24, 2018, the net peak area of the 77.2 keV full-energy peak in the sample was 683 ± 45, and the measurement time was 26123.02 s; on March 22, 2019, the net peak area decreased to the background level of 194 ± 49, and the measurement time was 86400.00 s. Conclusion In the 3D water phantom of the proton therapy system, 7Be can be generated from the spallation reaction between high-energy neutrons and oxygen in water. In addition, we find a full-energy peak at 77.2 keV with short half-life. The activity concentration of 7Be in the water sample is lower than the exemption level, but the activity concentration at sampling may not be the maximum activity concentration in the process of quality control. The inductive radionuclide 7Be produced in the 3D water phantom should be identified and properly evaluated in the assessment of occupational radiation hazards of proton therapy system.

ObjectiveTo explore the effect of Suanzaoren Tang combined with Ziwu Liuzhu acupuncture on the vertebral artery hemodynamics, inflammatory cytokines, and neurotrophic factors in the patients with cervical insomnia with syndrome of deficiency of both heart and spleen. MethodThe random number table method was employed to assign 164 patients with cervical insomnia with syndrome of deficiency of both heart and spleen treated in the First Clinical Medical School of Guangzhou University of Chinese Medicine from January 2018 to June 2021 into a control group and an observation group. The control group was orally administrated with 1-2 mg estazolam tablets before bed for 4 weeks, and the observation group with Suanzaoren Tang combined with Ziwu Liuzhu acupuncture for 4 weeks. The therapeutic efficacy and safety were observed. The Pittsburgh Sleep Quality Index (PSQI) score, polysomnography monitoring results, hemodynamics parameters of vertebral artery, and serum levels of inflammatory cytokines and neurotrophic factors were compared before and after treatment. ResultExcept 4 dropouts, the remaining 160 patients were included in this study, with 80 patients in each group. The observation group had higher total effective rate than the control group [92.50% (74/80) vs. 80.00% (64/80), χ2=5.270, P<0.05]. Compared with that before treatment, the therapies in both groups decreased the PSQI score, sleep latency time, awakening time, awakening times, serum levels of interleukin-1β (IL-1β), C-reactive protein (CRP), and tumor necrosis factor-α (TNF-α) (P<0.01). Meanwhile, they increased the proportion of rapid-eye-movement (REM) sleep, the diastolic blood flow velocity (Vd), systolic blood flow velocity (Vs), and mean blood flow velocity (MFV) of vertebral artery, as well as the serum levels of brain-derived neurotrophic factor (BDNF) and glial cell-derived neurotrophic factor (GDNF) (P<0.05, P<0.01). Moreover, the observation group had lower PSQI score, sleep latency time, awakening time, awakening times, and serum IL-1β, CRP, and TNF-α levels (P<0.01) and higher proportion of REM sleep, Vd, Vs, MFV of vertebral artery, and serum BDNF and GDNF levels (P<0.05, P<0.01) than the control group. ConclusionZiwu Liuzhu acupuncture combined with Suanzaoren Tang can improve blood circulation of vertebral artery, reduce the serum levels of inflammatory cytokine, and increase the serum levels of neurotrophic factors to improve the sleep quality of the patients with cervical insomnia with syndrome of deficiency of both heart and spleen.

ABSTRACT

Many studies have shown that circular RNAs (circRNAs) play a key regulatory role in the whole biological process of tumors. The purpose of this study was to explore the biological function and molecular mechanism of circ_0001666 in non-small cell lung cancer (NSCLC), so as to provide new targets for the diagnosis and treatment of NSCLC. Gene expression profiles were downloaded from Gene Expression Omnibus (GEO, GSE101586) and the differential genes were obtained by using GEO2R analysis. The quantitative real time polymerase chain reaction (qRT-PCR) was used to detect the expression level of circ_0001666 in NSCLC cells. Cell counting kit-8 (CCK-8) and Annexin V-FITC apoptosis detection kit were respectively used to assess the cell proliferation and apoptosis, where circ_0001666 was knockdown in NSCLC cells. The targeted relationship among mircoRNA 330-5p (miR-330-5p), circ_0001666, and high mobility group A2 protein (HMGA2) was verified by bioinformatics prediction, dual-luciferase reporter gene, RNA immunoprecipitation (RIP) and RNA pull down assay. The results showed that the expression of circ_0001666 in NSCLC cells was significantly up-regulated than that in normal lung epithelial cells. Circ_0001666 knockdown reduced the cell viability and promoted the apoptosis of NSCLC cells, which could be reversed by miR-330-5p inhibitors. MiR-330-5p is the downstream target of circ_0001666 and can be adsorbed by circ_0001666. HMGA2 is a target gene of miR-330-5p, which can be indirectly regulated by circ_0001666. The results suggest that circ_0001666 promotes the proliferation and inhibits apoptosis of NSCLC cells via miR-330-5p/HMGA2 axis.

ABSTRACT

Objective:To summarize the clinical manifestations and color Doppler ultrasonography of benign lymphoepithelial disease (BLL) in lacrimal gland, so as to improve the diagnostic accuracy of lacrimal BLL.Methods:Clinical manifestations and color Doppler flow imaging (CDFI) features of lacrimal BLL in 16 patients (2 males and 14 females, with 31 lesions) who visited the Second Hospital of Hebei Medical University from November 2014 to August 2019 were retrospectively analyzed.Results:The performance for lesions in patients with duration less than 3 months was scattered in irregular low echo, lesion blood flow signals within the rich (Adler Ⅱ level), pathologic examination results showed more lymphocytes were seen in the lacrimal matrix, and the myoepithelium of the lacrimal duct grew to form the epithelium-myocutaneous island. The ultrasonic feasures in patients with course of 3-6 months were in multiple categories such as circular low echo, "honeycomb" change, CDFI showed lesions with a lot of blood flow signals (Adler Ⅲ level), the pathological examination results indicated that there were a large number of lymphocytes and epithelial-musculocutaneous islands in the lacrimal matrix, and the lymphocytes were significantly increased compared with patients with the course of disease less than 3 months. The ultrasound results in patients with a course of more than 6 months showed lesions in multiple categories such as circular low echo, and large low echo, greater than 3 mm in diameter, CDFI showed lesions within the same large amounts of blood flow signals (Adler Ⅲ level), the pathological examination results were consistent with the course of 3 to 6 months. One patient had positive tuberculin test and 11 had higher IgG4 than normal.The number of lymphocytes increased with the prolongation of disease course.Conclusions:With the expert knowledge of color Doppler ultrasonographic characteristics of lacrimal gland BLL and with the serum IgG4 level helps to improve the accuracy of ultrasonic diagnosis.
