ABSTRACT
AIM:To evaluate the relationship between dry eye disease(DED)and physical and mental health in teachers, and to explore its mechanism and propose intervention measures.METHODS:Cross-sectional study. A total of 183 teachers from three primary and secondary schools in the urban area of Linyi City, Shandong Province were enrolled in the study. DED symptoms were quantified using the ocular surface disease index(OSDI)questionnaire. A compact version of the depression, anxiety, and stress scale(DASS-21)was used to evaluate psychological state. The relationship between potential influencing factors and DED was evaluated by independent sample t-test of quantitative variables and χ2test of classified variables. Logistic regression analysis was used for multivariate analysis to determine the influencing factors of DED. Pearson correlation coefficient was used to analyze the correlation between OSDI score and depression, anxiety and stress.RESULTS: There were 183 teachers, including 44 males(24.0%)and 139 females(76.0%), aged from 22 to 57 years, with an average age of(34.2±8.6)years. The prevalence of DED was 60.0%(109/183; 95%CI 52.4%-66.7%). The prevalence of depression was 26.2%(48/183; 95%CI 19.8%-32.7%); anxiety prevalence was 39.3%(72/183; 95%CI 32.2%-46.5%); and stress prevalence was 23.0%(42/183; 95%CI 16.8%-29.1%). The univariate analysis showed that increased age, increased working years, increased visual display terminal(VDT)application time, longer written working hours, reduced sleep hours, less alcohol consumption, and high scores of depression, anxiety and stress were all factors affecting DED(all P<0.05). Using depression scores as the psychological index, multivariate Logistic regression analysis showed that years of work, VDT application time, written working hours, sleep time, alcohol consumption and depression score were the influencing factors of DED(all P<0.05); Using anxiety scores as the psychological index, multivariate Logistic regression analysis showed that years of work, VDT application time, written working hours and stress scores were the influencing factors of DED(all P<0.05); Using stress scores as the psychological index, multivariate Logistic regression analysis showed that years of work, VDT application time, written working hours and stress scores were the influencing factors of DED(all P<0.05). OSDI scores were positively correlated with depression, anxiety, and stress scores in the DED group(P<0.05)and across all participants(P<0.05). In the severe DED group, OSDI scores were positively related to depression, anxiety, and stress scores(P<0.05).CONCLUSION: The prevalence of DED is high among the teachers. Alcohol consumption, reduced sleep, longer working years, longer VDT usage and longer written working hours are the influencing factors of DED. In severe DED group, DED is highly correlated with depression, anxiety, and stress. We should pay attention to teachers' DED and related physical and mental health problems, and actively prevent and make early diagnosis and treatment.
ABSTRACT
Objective:To investigate the clinical advantages of absorbable barbed wires in laparoscopy combined with choledochoscopy treatment of gallbladder polyps.Methods:The clinical data of 103 patients with gallbladder polyps who received laparoscopy combined with choledochoscopy treatment in The First People's Hospital of Lianyungang from February 2016 to March 2018 were retrospectively analyzed. Sixty-five patients in the observation group underwent gallbladder wall sutures with absorbable barbed wires, and thirty-eight patients in the control group underwent gallbladder wall sutures with common absorbable wires. The operative time, gallbladder wall suture time, intraoperative blood loss, average hospitalization time, and postoperative bile leakage were compared between the two groups.Results:There were no significant differences in intraoperative blood loss and average hospitalization time between the two groups ( P = 0.312, P = 0.114). In the observation group, gallbladder wall suture time and operative time were (5.58 ± 1.14) minutes and (60.71 ± 11.03) minutes, respectively, which were shorter than (6.32 ± 1.04) minutes and (68.24 ± 9.61) minutes in the control group ( t = 3.23, 3.50, P = 0.002, 0.001). No bile leakage occurred in the observation group and bile leakage occurred in four (10.5%) patients in the control group. There was a significant difference in bile leakage between the observation and control groups ( χ2 = 4.57, P = 0.032). Conclusion:Absorbable barbed wires for gallbladder wall sutures during operation in laparoscopy combined with choledochoscopy treatment of gallbladder polyps is safe and feasible. It can markedly shorten gallbladder wall suture time and operative time, decrease the incidence of bile leakage, and has a clinical advantage over common absorbable wires.
ABSTRACT
Objective:To explore the medical reference values, distribution characteristics and influencing factors of serum iodine in adults with different thyroid health conditions, and to evaluate the importance of serum iodine in evaluating individual iodine nutrition.Methods:From February 2017 to November 2018, multi-stage stratified cluster sampling was used to select one community and one agricultural (fishing) village in the coastal Yingkou City and the inland areas of Shenyang City of Liaoning Province as survey sites. Cluster sampling of adults over 18 years old who had lived for five years were conducted with questionnaire survey, clinical physical examination and thyroid ultrasound examination. Fasting venous blood samples and one random urine sample were collected from all subjects for serum iodine, thyroid hormone, antibody and urine iodine detection. The 95% medical reference value of serum iodine was established by using the percentage quantile method, and the reference value, distribution characteristics and influencing factors of serum iodine in adults with different thyroid health status were analyzed. The diagnostic value of iodine nutritional indicators in thyroid diseases was evaluated by the receiver operating characteristic (ROC) curve.Results:A total of 2 931 adults were surveyed, with serum iodine levels of 62.1 (53.6, 72.2) μg/L, ranging from 5.6 to 642.3 μg/L; urine iodine was 167.6 (111.2, 244.2) μg/L, and the overall iodine level was at an appropriate level. A total of 1 089 patients with thyroid diseases were examined, with a detection rate of 37.2% (1 089/2 931); among them, there were 597 cases of thyroid nodules, 56 cases of endemic goiter, 42 cases of hypothyroidism, 161 cases of subclinical hypothyroidism, 27 cases of hyperthyroidism, 18 cases of subclinical hyperthyroidism, and 474 cases of autoimmune thyroid disease (AITD). There was a statistically significant difference in the detection of thyroid diseases among adults with different levels of serum iodine (χ 2 = 13.80, P < 0.05). The reference values of serum iodine in normal adults, hypothyroidism (without thyroid hormone intervention), hyperthyroidism (without anti thyroid hormone drug treatment), AITD, endemic goiter, and thyroid nodules were 37.2 - 103.0, 12.5 - 52.8, 49.9 - 163.1, 34.3 - 129.3, 27.3 - 92.8, and 37.9 - 119.5 μg/L, respectively. The ROC curve analysis results showed that the serum iodine area under curve(AUC) of patients with hyperthyroidism, subclinical hyperthyroidism, endemic goiter, thyroid nodules, and AITD were 0.94, 0.61, 0.55, 0.53, and 0.52, respectively. The results of univariate analysis showed that there were statistically significant differences in adult serum iodine levels among different positions, regions, age, education level, occupation, iodine intake, blood pressure, and body mass index ( P < 0.05). Conclusions:There are significant differences in serum iodine levels among adults with different thyroid health conditions, and evaluation standards and systems should be developed separately. Serum iodine is an important indicator for evaluating individual iodine nutrition.
ABSTRACT
Inductively coupled plasma mass spectrometry (ICP-MS) was applied to determine the concentrations of lead (Pb), cadmium (Cd) and arsenic (As) in Lindera aggregata (Sims) Kosterm. The physiologically based extraction test (PBET) digestion in vitro/Caco-2 cell model was established to investigate the bioaccessible contents of Pb, Cd and As in decoction of Lindera aggregata (Sims) Kosterm. The target-organ toxicity dose modification of HI method (TTD) was used to evaluate the cumulative risk caused by the combined exposure of the total levels of Pb, Cd and As in Lindera aggregata (Sims) Kosterm. and the bioaccessible contents in the decoction. The results showed that the total contents of Pb, Cd and As in 4 batches of samples were in the range of 2.901-3.872, 1.299-1.800 and 0.062-0.216 mg·kg-1, respectively. After transportation by Cacco-2 cells, the bioaccessible contents of Pb, Cd, and As in the decoction were in the range of 0.045-0.080, 0.070-0.112 and 0.004-0.018 mg·kg-1. The results of risk assessment showed that calculated by the total amounts of heavy metals in the Lindera aggregata (Sims) Kosterm., for the end points of nervous system, the cumulative risks of co-exposure of heavy metals in 3 batches of samples were of concern. After decoction and transportation by Caco-2 cells, for the end points of cardiovascular system, blood, nervous system, kidney and testis, the TTD modification of HI values of all batches of samples were less than 1, and the health risks were acceptable. The study provided methodology basis for a more objective assessment of the health risks of heavy metals and harmful elements in traditional Chinese medicine and for a more scientific limit standard of heavy metals and harmful elements.
ABSTRACT
Objective:To investigate the characteristics of renal disease spectrum in children aged 0-3 years old, and to evaluate the clinical value of renal biopsy in children aged 0-3 years old with renal diseases.Methods:It was a retrospective analysis study. The children aged 0-3 years old with kidney diseases receiving renal biopsy and having complete clinical data in Shanghai Children's Hospital from January 1, 2009 to December 31, 2020 were enrolled. The clinical and pathological data of the children were collected. The spectrum of renal diseases, clinical phenotype, renal pathology, and the relationship between renal pathology/genotype and clinical phenotype were analyzed.Results:A total of 117 children aged 0-3 years old with kidney diseases were enrolled in the study, accounting for 6.5% (117/1 790) of all children (0-18 years old) with renal biopsies during the same period. There were 77 males and 40 females. The age was (2.20±0.51) years old (5-35 months). All cases of renal biopsies in children aged 0-3 years old were successful without serious complications. Nephrotic syndrome was the common clinical phenotype of kidney diseases in children aged 0-3 years old (59.0%, 69/117), followed by hematuria and proteinuria (29.1%, 34/117). Primary glomerular disease (69.2%, 81/117) was the major clinical type of renal diseases, followed by hereditary kidney diseases (29.1%, 34/117), in which Alport syndrome was the main hereditary kidney disease (79.4%, 27/34). Renal pathological types of children aged 0-3 years old were mainly distributed in minimal change disease (30.8%, 36/117), followed by glomerular minor lesion (26.5%, 31/117), mesangial proliferative glomerulonephritis (15.4%, 18/117), and focal segmental glomerulosclerosis (10.3%, 12/117). Among 40 children aged 0-3 years old with hematuria with/without proteinuria, 25 cases were diagnosed as Alport syndrome by abnormal immunofluorescence of type IV collagen in renal tissues. Among the 28 children with kidney diseases who underwent genetic testing, 23 cases had gene mutations, mainly in COL4A5 gene (60.9%, 14/23), among which 4 children had gene mutations in 8 children with refractory nephrotic syndrome. Among the children aged 0-3 years old with clinical manifestations of hematuria, the proportion of gross hematuria in children diagnosed with Alport syndrome (59.3%, 16/27) was significantly higher than that in children without Alport syndrome (20.0%, 3/15, χ2=5.999, P=0.014). Conclusions:Primary glomerular disease is the principal type of kidney diseases in children aged 0-3 years old, followed by hereditary kidney disease. Attention should be paid to children aged 0-3 years old with gross hematuria. Renal biopsy in children aged 0-3 years old is safe and reliable, and it is an essential means for the diagnosis of renal diseases. Renal biopsy combined with gene testing can better understand the etiology of kidney diseases and guide treatment in children aged 0-3 years old.
ABSTRACT
Objective:To investigate the utilization of health management services and its influencing factors among new urban population.Methods:It is a cross-sectional study. From July 2020 to March 2021, a stratified random sampling method was used to extract 1978 new urban population in Jining city, and an anonymous self-administered questionnaire survey was conducted using a self-made questionnaire ′Residents Health Questionnaire′. The survey included general demographic characteristics, personal behavior lifestyle and medical care status. The χ2 test and binary logistic regression were used to analyze the factors influencing the utilization of health management services by new urban population. Results:The overall utilization of health management services in the new urban population was 47.22%. There were significant differences in utilization of health management services among new urban population with different gender, age, education level, occupation and monthly income. Binary logistic regression analysis showed that female ( OR=1.354, 95% CI: 1.094-1.676), people aged over 60 years ( OR=1.873, 95% CI: 1.413-2.483), people with a mean monthly income over 3 000 yuan ( OR=1.498, 95% CI: 1.123-1.997), people engaged in light manual labor ( OR=1.596, 95% CI: 1.003-2.539), people who exercise regularly( OR=2.400, 95% CI: 2.028-2.841) and people having social basic medical insurance ( OR=2.633, 95% CI: 2.042-3.394) had better utilization of health management projects. People who sat more than 3 hours a day ( OR=0.630, 95% CI: 0.532-0.745) had lower utilization of health management care. Conclusion:The utilization of health management projects in the new urban population is low. Gender, age, monthly income, physical exercise, sedentary time, daily labor intensity and social basic medical insurance status are the main influencing factors.

We found 15 eyes(15.0%)who underwent vitrectomy after the combination treatment. The vitrectomy rates of the three groups were 2.9% in group A, 13.9% in group B, and 34.7% in group C. We found no instances of retinal detachment after the treatments. Most patients demonstrated improved BCVA and CMT values with the treatments.CONCLUSION: PRP combined with IVC is safe and effective in patients with different PDR stages.
ABSTRACT
@#Objective To investigate the feasibility and safety of DynaCT microwave ablation (MWA) guided by 3D iGuide puncture technology for lung cancer. Methods The clinical data of 19 patients with primary or metastatic lung cancer who underwent DynaCT MWA from June 2019 to December 2020 in our hospital were retrospectively analyzed, including 15 males and 4 females with an average age of 64.9±11.7 years. The technical success rates, adverse reactions and complications, postoperative hospital stay, and local therapeutic efficacy were recorded. Results Technical success rate was 100.0%. The mean time required to target and place the needle was 15.7±3.7 min and the mean ablation time was 5.7±1.6 min. Thirteen patients underwent biopsy synchronously before the ablation, and 10 (76.9%) patients had positive pathological results. The main adverse reactions were pain (7/19, 36.8%), post-ablation syndrome (4/19, 21.1%) and cough (2/19, 10.5%). The minor complications were pneumothorax (6/19, 31.6%), hemorrhage (5/19, 26.3%), pleural effusion (2/19, 10.5%) and cavity (1/19, 5.3%). Three patients had moderate pneumothorax and received closed thoracic drainage. The median hospitalization time after ablation was 2.0 (2.0, 3.0) d, and no patient died during the perioperative period. The initial complete ablation rate was 89.5% (17 patients) and the incomplete ablation rate was 10.5% (2 patients) at 1-month follow-up, and no local progression was observed. Conclusion DynaCT MWA of lung cancer under the guidance of 3D iGuide system is safe and feasible with a high short-term local control rate, but the long-term efficacy remains to be further observed.
ABSTRACT
Objective:To evaluate the efficacy of intra-articular injection of autologous platelet-rich plasma (PRP) combined with Tongbi Powder fumigation in the treatment of early knee osteoarthritis (KOA).Methods:Randomized controlled trial. Totally 160 patients with KOA in Tai'an Second Hospital of Traditional Chinese Medicine were enrolled between March 2021 and March 2022. According to random number table method, they were divided into two groups, with 80 cases in each group. The control group was given routine treatment, while observation group was given intra-articular injection of autologous PRP combined with Tongbi Powder fumigation. All were treated for 3 weeks. The knee function was evaluated by Western Ontario and McMaster University (WOMAC) osteoarthritis index. The activities of daily living were evaluated by Lysholm knee scale (LKS). The pain degree was evaluated by VAS. The levels of interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) were detected by ELISA. The adverse reactions during treatment were observed and recorded. The clinical efficacy was evaluated.Results:The total effective rate of the observation group was 95.0% (76/80), and that of the control group was 77.5% (62/80), with statistical significance ( χ2=10.33, P<0.01). At 1, 3 and 6 months after treatment, the WOMAC score of the observation group was lower than that of the control group ( F=15.63, P<0.01), the LKS score was higher than that of the control group ( F=55.23, P<0.01), and the VAS score was lower than that of the control group ( F=11.93, P<0.01). After treatment, the observation group IL-1β [(51.75±2.74)μg/L vs. (63.38±3.31) μg/L, t=24.21], TNF- α [(10.58±1.25) μg/L vs. (11.62±1.84) μg/L, t=4.18] were lower than those in the control group ( P<0.01). The incidence of adverse reactions was 10.0% (8/80) in the observation group and 7.5% (6/80) in the control group, without statistical significance ( χ2=0.31, P=0.576). Conclusion:Intra-articular injection of autologous PRP combined with Tongbi San fumigation can effectively improve knee function and activities of living ability, relieve pain symptoms, reduce inflammatory response and improve clinical curative effect in early KOA.
ABSTRACT
OBJECTIVE To eva luate the economy of loratinib versus crizo tinib in the first-line treatment of anaplastic lymphoma kinase （ALK）-positive advanced non-small cell lung cancer （NSCLC）from the perspective of China ’s health system ， and to provide reference for the product pricing and related medical decisions of the drug in other regions of China except for Hong Kong. METHODS Markov model and partition survival model both constructed based on the CROWN data （the simulation time limit was 10 years and the cycle period was 4 weeks）；the quality adjusted life year （QALY）was used as the outcome index to calculate the incremental cost-effectiveness ratio （ICER）. One-way sensitivity analysis ，probability sensitivity analysis and scenario analysis were used to verify the robustness of the results. RESULTS The basic analysis results based on Markov model showed that compared with crizotinib group ，the per capita cost of loratinib group increased by 17 867 588.63 yuan，the per capita utility increased by 1.76 QALYs，and the ICER was 10 152 038.99 yuan/QALY. The basic analysis results based on the partition survival model showed that compared with the crizotinib group ，the Δ 基金项目：江苏省博士后科研资助计划项目（No.2021K496C）； per capita cost of loratinib group increased by 18 009 592.54 2020年度高校哲学社会科学研究一般项目（No.2020SJA0070） yuan，the per capita utility increased by 1.74 QALYs，and the ＊硕士研究生 。研究方向 ：药物经济学 、卫生经济与政策 。 E-mail：sunlei_cpu@163.com ICER was 10 350 340.54 yuan/QALY.

The results of probability sensitivity analysis showed that when 1-3 times of China ’s per capita GDP in 2020 was taken as the willingness to pay threshold ，the probability of loratinib being economical was 0. The recommended unit price of loratinib per 100 mg was 657.10-815.60 yuan. CONCLUSIONS For patients with ALK-positive advanced NSCLC ，loratinib is more effective than crizotinib in the first-line treatment ，but it is not economical under the current price ；reasonably lowering the price of loratinib can increase the probability of its economy.
ABSTRACT
Objective:To investigate the clinical value of ultrasound shear wave dispersion (SWD) imaging in assessing the hepatic inflammation activity in patients with chronic hepatitis B.Methods:Fifty-two patients with chronic hepatitis B who underwent liver biopsy in Peking University Third Hospital and Beijing Ditan Hospital Affiliated to Capital Medical University from December 2020 to December 2021 were prospectively enrolled.Liver stiffness (LS) and shear wave dispersion slope (SWDS) were measured by SWD imaging in all participants. Baseline data and laboratory indexes of liver function were collected.Liver inflammation grading(G0-G4) and fibrosis staging (S0-S4) were determined by pathological examination. The relationship between SWDS and various indicators was analyzed by univariate and multivariate linear regression analysis. The participants were grouped according to the pathological grading of hepatic inflammatory activity. The differences of various indexes among three groups were compared, and the correlations between SWDS, LS and laboratory indicators and hepatic inflammatory activity were analyzed. The ROC curve was used to evaluate the diagnostic performances of ultrasound and laboratory indicators for hepatic inflammation activity, and the diagnostic accuracy of different indicators was compared by Delong test.Results:Inflammation and fibrosis were both independent affecting factors of SWDS (all P<0.05); there were significant differences in alanine transaminase(ALT), aspartate aminotransferase(AST), LS and SWDS among groups with different inflammatory activities (all P<0.05). The SWDS and LS of the G3 and G2 groups were statistically higher than those of the G1 group (all P<0.001). ALT was only significantly different between G1 group and G2 group ( P<0.05), and AST was only significantly different between G1 group and G3 group ( P<0.05); The SWDS and LS showed strongly positive correlation ( rs=0.728, P<0.001) and moderately positive correlation ( rs=0.679, P<0.001) with hepatic inflammatory activity, respectively; while the correlations between ALT, AST and hepatic inflammatory activity were weaker( rs=0.376, P<0.05; rs=0.485, P<0.001). The area under the ROC curve, sensitivity and specificity of SWDS for diagnosing hepatic inflammation ≥G2 grade were 0.965, 0.933 and 0.865, respectively. Conclusions:SWDS has certain value in evaluating the hepatic inflammatory activity of ≥G2 grade in patients with chronic hepatitis B.
ABSTRACT
Objective To explore the potential targets of triclosan in the treatment of nonalcoholic fatty liver disease(NAFLD) and to provide new clues for the future research on the application of triclosan. Methods The targets of triclosan and NAFLD were obtained via network pharmacology.The protein-protein interaction network was constructed with the common targets shared by triclosan and NAFLD.The affinity of triclosan to targets was verified through molecular docking.Gene ontology(GO) annotation and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment were carried out to analyze the key targets and the potential mechanism of action.NAFLD model was established by feeding male C57BL/6J mice with high-fat diet for 12 weeks.The mice were randomly assigned into a model group and a triclosan group [400 mg/(kg·d),gavage once a day for 8 weeks].The hematoxylin-eosin(HE) staining was used for observation of the pathological changes and oil red O staining for observation of fat deposition in mouse liver.Western blotting was employed to detect the protein level of peroxisome proliferator-activated receptor alpha(PPARα) in the liver tissue. Results Triclosan and NAFLD had 34 common targets,19 of which may be the potential targets for the treatment,including albumin(ALB),PPARα,mitogen-activated protein kinase 8(MAPK8),and fatty acid synthase.Molecular docking predicted that ALB,PPARα,and MAPK8 had good binding ability to triclosan.KEGG pathway enrichment showcased that the targets were mainly enriched in peroxisome proliferator-activated receptor signaling pathway,in which ALB and MAPK8 were not involved.Triclosan alleviated the balloon-like change and lipid droplet vacuole,decreased the lipid droplet area,and up-regulated the expression level of PPARα in mouse liver tissue. Conclusion PPARα is a key target of triclosan in the treatment of NAFLD,which may be involved in fatty acid oxidation through the peroxisome proliferator activated receptor signaling pathway.

OBJECTIVE To evaluate the econo mical efficiency of ensatinib i n the first-line treatment of anaplastic lymphoma kinase（ALK）positive-advanced non-small cell lung cancer （NSCLC），so as to provide reference for China ’s medical insurance decision-making and rational drug use in clinic. METHODS A three-state partitioned survival model was constructed from the perspective of China ’s health system ，based on the data of the international multi-center phase Ⅲ clinical trial （eXalt3 trail），with simulation time limit of 10 years，cycle period of 30 days. The economical efficiency of ensatinib was compared with that of crizotinib（standard treatment ）in the first-line treatment of ALK positive-advanced NSCLC. The incremental cost-effectiveness ratio （ICER） was calculated with quality-adjusted life years （QALYs） as utility index. The stability of basic analysis results was validated through uncertainty analysis. RESULTS The basic analysis results showed that compared with crizotinib group ， incremental cost per capita of ensatinib group was －343 370.36 yuan，incremental utility per capita was 0.76 QALYs，ICER was －454 292.25 yuan/QALY，which was far lower than the willingness-to-pay （WTP）threshold of 1 time of China ’s per capita gross domestic product （GDP，80 976 yuan）in 2021. The results of univariate sensitivity analysis showed that progression-free survival （PFS）status utility ，progression of disease （PD）status utility and subsequent treatment cost of crizotinib had a greater impact on ICER，but these parameters could not cause the reversal of basic analysis results. Probabilistic sensitivity analysis showed that with 1 time of China ’s per capita GDP in 2021 as the WTP threshold ，the probability of ensatinib group ’s treatment possessed economical efficiency was 100％. In the situational analysis ，ICER obtained by changing the ensatinib group ’s follow-up treatment regimen was －217 671.43 yuan/QALY，which was far below WTP threshold. CONCLUSIONS For Chinese patients with ALK positive-advanced NSCLC ，compared with commonly used the first-line treatment （crizotinib），ensartinib is economical and absolutely dominant.
ABSTRACT
Platinum anti-tumor drugs are currently the most widely used first-line chemotherapeutic drugs in clinical practice, and their curative effects are remarkable. However, the problems of platinum drug resistance in non-small cell lung cancer, breast cancer, ovarian cancer and others seriously limit effectiveness and clinical application of platinum drugs. The occurrence of platinum drug resistance is caused by many factors. At present, the resistance mechanism of platinum drugs mainly includes the following aspects: decreasing the accumulation of platinum in cells, increasing the inactivation of platinum in cells, repairing DNA damage and tumor cell apoptosis inactivation. This article reviews the drug resistance mechanism and coping strategy of platinum anti-tumor drugs, providing ideas for the development of platinum anti-tumor drugs and references for overcoming clinical platinum drug resistance.
ABSTRACT
Objective:To evaluate the effects of simultaneous integrated boost intensity-modulated radical radiotherapy (SIB-IMRT) on the long-term prognosis of patients with cervical and upper thoracic esophageal cancer.Methods:From January 2011 to December 2014, a retrospective analysis was performed in 172 patients with cervical and upper thoracic esophageal cancer who were eligible for IMRT. First, the prognosis of all the patients was evaluated using single factor and multivariate analyses. According to the different irradiation method of the patients, the patients were divided into two groups, one of which received conventional IMRT (C-IMRT) and the other of which received SIB-IMRT. Propensity score matching (PSM) analysis was applied to match the two groups of patients and to determine the treatment efficacy of patients after PSM, prognostic factors, failure modes, and side effects. SPSS19.0 statistical software was used to conduct statistical analysis.Results:The median overall survival (OS) and progression-free survival (PFS) times of all the patients were 30 months and 20 months, respectively. The fact whether the surrounding tissues and organs of esophageal lesions were invaded, clinical node staging (cN staging), chemotherapy, and GTV-maximum transverse diameter were observed to be independent influencing factors of OS and PFS in all the patients ( P<0.001, P=0.013, 0.005, 0.002; P<0.001, P=0.017, 0.034, 0.002). In addition, the independent influencing factors of PFS showed short-term efficacy ( P=0.036). After PSM, there were 54 patients in each of the two groups. The result of multivariate analysis showed that the fact whether the surrounding tissues and organs of esophageal lesions were invaded, cN staging, cTNM staging, prescribed dose, GTV-maximum transverse diameter, and irradiation method were independent factors affecting the OS ( P<0.001, P=0.008, 0.014, 0.021, 0.010, 0.008). Similarly, the fact whether the surrounding tissues and organs of esophageal lesions were invaded, cN staging, and GTV-maximum transverse diameter were observed to be independent factors that affect the PFS of patients ( P<0.001, P=0.044, 0.013). The difference in the total failure rate (70.4% vs. 50.0%) and the local regional recurrence rate (61.1% vs. 31.5%) between the C-IMRT and SIB-IMRT groups after treatment was significant ( χ2=4.68, 9.53, P=0.031, 0.002). The incidence of radiation pneumonitis of grade ≥ 1 in the C-IMRT group was significantly higher than that of the SIB-IMRT group ( χ2=6.16, P=0.046), whereas the leukocyte suppression of grade ≥ 2 in the C-IMRT group was significantly lower than that in the SIB-IMRT group ( χ2=12.77, P=0.005). Conclusions:As shown by the result of this study, compared with C-IMRT, SIB-IMRT can improve the OS of patients with cervical and upper thoracic esophageal cancer to a certain extent. Whether SIB-IMRT can improve the PFS of patients requires further research.
ABSTRACT
Objective:To analyze the morphology and distribution characteristics of subchondral bone cysts of the talus by CT three-dimensional reconstruction.Methods:A total of 176 patients diagnosed with subchondral bone cyst of the talus after CT scan of the ankle or foot from 2015 to 2020 were retrieved from the imaging report database of Tianjin Hospital, including 77 males and 99 females, aged 14-84 years［(56.1±14.0)years］. After three-dimensional reconstruction of the talus and cyst area by Mimics 20.0 software, an equal 2×2 grid configuration was constructed to divide the domed articular surface into four regions: anteromedial, anterolateral, posteromedial and posterolateral. For subchondral cyst of the talus, area involved under grid localization, gender, age and side of the onset were recorded. The anteroposterior diameter, transverse diameter, depth, surface area and volume of the subchondral bone cyst of the talus were measured.Results:Subchondral cyst of the talus was anteromedial in 131 patients (74.4%), anterolateral in 5(2.8%), posteromedial in 34(19.3%), and posterolateral in 6(3.4%). Subchondral cyst of the talus occurred in the older aged (≥60 years) for 78 patients (44.3%), in the middle aged (45-59 years) for 62(35.2%), in young adults for 32(18.2%), and in preadolescents for 4(2.3%). The age composition of the subchondral cyst of the talus involving the anteromedial, anterolateral, posteromedial and posterolateral regions was 59(49, 64)years, 44(39, 45)years, 61(54, 68)years and 40(22, 58) years, respectively (all P<0.01). There were no statistically significant differences in gender and side of the onset (all P>0.05). The anteroposterior diameter of the subchondral bone cysts located anteromedially, anterolaterally, posteromedially and posterolaterally was (9.7±4.4)mm, (3.5±1.1)mm, (10.3±4.4)mm and (2.1±0.8)mm, respectively; the transverse diameter was (5.4±1.7)mm, (3.9±1.8)mm, (5.9±2.2)mm and (3.4±1.1)mm, respectively; the depth was (7.1±2.4)mm, (3.2±2.2)mm, (8.2±3.0)mm and (3.9±1.9)mm, respectively; the surface area was 156.1(82.6, 198.2)mm 2, 23.0(21.4, 28.9)mm 2, 180.0(75.1, 230.4)mm 2 and 28.0(20.3, 36.7)mm 2, respectively; the volume was 77.1(37.1, 129.1)mm 3, 23.9(14.2, 37.8)mm 3, 104.6(37.7, 157.4)mm 3 and 13.0(10.4, 16.0)mm 3, respectively. When comparing the anteroposterior diameter, transverse diameter, depth, surface area and volume of the subchondral bone cysts in the anteromedial and posteromedial regions with the anterolateral and posterolateral regions, the differences were statistically significant (all P<0.01) except for the transverse diameter of the subchondral bone cysts in the anteromedial region and the anterolateral region ( P>0.05). In addition, the depth of subchondral bone cysts in the anteromedial region was significantly greater than that in the posteromedial region ( P<0.05). Conclusions:Subchondral bone cysts of the talar are commonly found in the middle- and old-aged population. Anteromedial lesions of the talar dome are the most commonly seen, with large and deeply involved cysts, followed by posteromedial lesions of the dome, while anterolateral and posterolateral lesions of the dome are less common and have smaller cyst sizes. An equal 2×2 grid configuration for talar cysts is useful in positioning and characterizing bone cysts, and can assist clinicians in accurately diagnosing and treating bone cysts.
ABSTRACT
Objective:To understand the knowledge, attitude and behavior of volume management of maintenance hemodialysis patients, so as to provide a basis for standardizing volume management and carrying out refined individual care.Methods:By means of convenience sampling, 608 patients from 4 hospitals who received regular dialysis treatment in Xuzhou and Yancheng hemodialysis rooms in October 2021 were selected as subjects. Patients were surveyed by a self-designed knowledge questionnaires of volume management, Maintenance Hemodialysis Patients′ Capacity Management Behavior Scale and Self-Efficacy Scale. Questionnaires were collected through the questionnaire star.Results:A total of 608 valid questionnaires were collected. The knowledge dimension scored 8.21 ± 2.27 , atitude dimension scored 7.36 ± 2.06 and behavior dimension scored 15.07 ± 4.22. Multiplelinear regression analysis showed that age, dialysis age and self-care ability were predictors of volume management knowledge score ( t=-2.07, 2.35, -3.90, all P<0.05 ). Medical insurance type was a predictor of volume management attitude score ( t=-2.17, P<0.05). Education level was a predictor of volume management behavior score ( t=3.04, P<0.05). Conclusions:The capacity management knowledge and capacity management attitude of maintenance hemodialysis patients is in the medium level, but with poor volume management executive ability. It is suggested that medical staff carry out health education related to volume management according to different characteristics of patients, and effectively improve patients′ volume management ability.
ABSTRACT
Objective:To learn about the levels of serum iodine and thyroid function indicators in adults with normal thyroid function in Liaoning Province, to establish the medical reference value range of serum iodine, and to explore the relationship between serum iodine and thyroid function indicators.Methods:From February 2017 to December 2018, one subdistrict and one rural township were selected as the survey sites in the coastal area (Gaizhou City of Yingkou) and inland area (Kangping County of Shenyang) of Liaoning Province, respectively. Permanent residents aged 18 and older who have lived there for 5 years or more were selected as the survey subjects. Blood samples were collected to test the levels of serum iodine and thyroid function indicators [thyroid stimulating hormone (TSH), free triiodothyronine (FT 3), free thyroxine (FT 4), thyroid peroxidase antibody (TPOAb) and thyroglobulin antibody (TgAb)]. The percentile method was used to establish the 95% medical reference value range of serum iodine in adults with normal thyroid function, and Pearson correlation analysis was used to analyze the correlation between serum iodine and thyroid function indicators. Results:A total of 1 621 adults with normal thyroid function were examined, the median serum iodine was 62.0 μg/L, and the 95% medical reference value range was preliminarily determined as 37.0-103.0 μg/L. Among them, the medians serum iodine of males and females (826 and 795 cases) were 62.3 and 61.0 μg/L, respectively, and there was no significant difference between genders ( Z=- 1.26, P = 0.210). The medians serum iodine of adults in coastal and inland areas (827 and 794 cases) were 61.7 and 61.9 μg/L, respectively, and there was no significant difference between areas ( Z = - 0.16, P = 0.870). The medians serum iodine of adults aged 18 - 29, 30 - 39, 40 - 49, 50 - 59 and 60 - 80 (385, 392, 378, 253 and 213 cases) were 61.0, 61.0, 63.0, 65.0 and 62.0 μg/L, respectively, and the difference between ages was statistically significant ( H = 14.52, P = 0.006). Pearson correlation analysis showed that serum iodine was weakly correlated with the level of FT 4 ( r = 0.17, P < 0.001), but not with the levels of TSH, TPOAb and TgAb ( P > 0.05). Conclusions:This study has established the medical reference value range of serum iodine in adults with normal thyroid function in Liaoning Province. Serum iodine is not correlated with the levels of TSH, TPOAb and TgAb.
ABSTRACT
@#Objective To evaluate the safety and efficacy of microwave ablation (MWA) in the treatment of lung tumors. Methods The clinical data of 31 patients with lung neoplasms treated with MWA from January 2019 to August 2020 in a single center were retrospectively analyzed. There were 17 males and 14 females at an age of 63.4±10.4 years. The characteristics of the lesions, technical success rate, technical efficiency, local progression rate, adverse reactions and complications were recorded in detail. Results There were 39 target lesions with an average diameter of 20.2±10.6 mm. A total of 36 MWA procedures were completed. The initial technical success rate was 84.6% (33/39), and the technical efficiency was 92.3% (36/39). The median postprocedure hospital stay was 2.0 (2.0, 3.0) d. A total of 12.9% (4/31) of the patients had local progression, and the local control rate was 87.1%. The main adverse reactions were pain (12/36, 33.3%), cough (6/36, 16.7%), post-ablation syndrome (6/36, 16.7%) and pleural effusion (3/36, 8.3%). The main complications were pneumothorax (11/36, 30.6%), hemorrhage (8/36, 22.2%), cavitation (2/36, 5.6%) and pulmonary infection (1/36, 2.8%). The median follow-up time was 13.0 (8.0, 18.0) months. No patient died during the follow-up. Conclusion MWA is safe and effective in the treatment of lung tumors with controllable complications. Successive researches with large sample, and medium and long-term follow-ups are needed to explore the significance of combined therapies.
ABSTRACT
Objective To investigate biomechanical characteristics of femoral neck fracture with different reduction qualities. Methods Three cases of Sawbones artificial femoral models were selected, and two cases of Pauwel III femoral neck fracture were modeled. Three cannulated screws were inserted into the models in the form of inverted triangle to fix the fracture. Two cases maintained different reduction qualities (defined as Model 1 and Model 2). In the 3 third case, no modeling operation was performed (defined as intact model). Then the strain gauges were respectively pasted on regions of interest of the 3 femoral models. Finally, the femur model was applied with the vertical load on mechanical testing machine. Results When the displacement of femoral head reached 4 mm, the average load of intact model, Model 1 and Model 2 was (236.30±5.35), (196.57±3.56), (69.50±2.95) N, showing significant differences. When the displacement of femoral head reached 5 mm, the average load of intact model, Model 1 and Model 2 was (276.7±3.40)，(232.93±2.64)，(80.83±4.54) N, showing significant differences. Conclusions The lower the reduction quality of the femoral neck fracture, the weaker the ability of the femur to bear stress, the higher the probability of nonunion, re-fracture and femoral head necrosis in the process of postoperative rehabilitation.
