ABSTRACT

@#Objective    To investigate the feasibility of magnamosis rings designed based on magnetic compression technique in esophageal anastomosis reconstruction. Methods    According to the anatomical characteristics of esophagus in SD rats, the esophageal magnamosis rings were designed. SD rats were used as animal models (n=10, 5 males and 5 females) to complete the magnetic anastomosis reconstruction of the cervical esophagus using magnamosis rings, and the operation time, animal survival, postoperative complications, magnetic rings excretion time were recorded. Two weeks after operation, the rats were killed, and the esophageal anastomotic specimens were obtained. The blasting pressure of the anastomotic site was measured and the formation of the anastomotic site was observed with naked eyes. Results    Esophageal magnamosis was successfully performed in 10 SD rats, and the median operation time was 11 (8-13) min. All rats survived without anastomotic leakage, anastomotic stenosis, or magnetic rings incarceration. The magnetic rings were discharged after 8 (5-10) days and the burst pressure was higher than 300 mm Hg. Visual observation showed that the anastomotic muscle healed well and the mucosa was smooth. Conclusion    The magnetic compression technique  can be used for anastomosis reconstruction of esophagus, which has the advantages of simple operation and reliable anastomosis effect, and has clinical application prospect.

ABSTRACT

Objective@#To investigate the feasibility of cine three-dimensional (3D) balanced steady-state free precession (b-SSFP) imaging combined with a non-local means (NLM) algorithm for image denoising in evaluating cardiac function in children with repaired tetralogy of Fallot (rTOF). @*Materials and Methods@#Thirty-five patients with rTOF (mean age, 12 years; range, 7–18 years) were enrolled to undergo cardiac cine image acquisition, including two-dimensional (2D) b-SSFP, 3D b-SSFP, and 3D b-SSFP combined with NLM. End-diastolic volume (EDV), end-systolic volume (ESV), stroke volume (SV), and ejection fraction (EF) of the two ventricles were measured and indexed by body surface index. Acquisition time and image quality were recorded and compared among the three imaging sequences. @*Results@#3D b-SSFP with denoising vs. 2D b-SSFP had high correlation coefficients for EDV, ESV, SV, and EF of the left (0.959– 0.991; p < 0.001) as well as right (0.755–0.965; p < 0.001) ventricular metrics. The image acquisition time ± standard deviation (SD) was 25.1 ± 2.4 seconds for 3D b-SSFP compared with 277.6 ± 0.7 seconds for 2D b-SSFP, indicating a significantly shorter time with the 3D than the 2D sequence (p < 0.001). Image quality score was better with 3D b-SSFP combined with denoising than with 3D b-SSFP (mean ± SD, 3.8 ± 0.6 vs. 3.5 ± 0.6; p = 0.005). Signal-to-noise ratios for blood and myocardium as well as contrast between blood and myocardium were higher for 3D b-SSFP combined with denoising than for 3D b-SSFP (p < 0.05 for all but septal myocardium). @*Conclusion@#The 3D b-SSFP sequence can significantly reduce acquisition time compared to the 2D b-SSFP sequence for cine imaging in the evaluation of ventricular function in children with rTOF, and its quality can be further improved by combining it with an NLM denoising method.

ABSTRACT

ObjectiveTo investigate the association of tuberous sclerosis gene 1/2 (TSC1/2) mutation with disease severity and prognosis in patients with hepatocellular carcinoma (HCC), and to provide a feasible basis for the diagnosis and treatment of HCC. MethodsA total of 492 patients with HCC who were admitted to The Affiliated Hospital of Jiangsu University from January 2012 to January 2020 were enrolled, among whom 59 had TSC1/2 mutations (20 with TSC1 mutations, 41 with TSC2 mutations, and 2 had both TSC1 and TSC2 mutations). The clinical features of patients with TSC1/2 mutations were analyzed, and the association of TSC1/2 mutations with the clinical stage of HCC was analyzed. The 35 patients in the mutation group and 35 in the non-mutation group were followed up for 3 years to observe the effect of TSC1/2 mutations on the prognosis of HCC. The chi-square test was used for comparison of categorical data between groups; the Kruskal-Wallis H test was used for comparison of ranked data between groups; a multivariate logistic regression analysis was used to investigate association; the Kaplan-Meier survival analysis was used to analyze follow-up data. ResultsFor the 492 patients with HCC, the overall TSC1/2 mutation rate was 11.99%. There were no significant differences in sex, age, Child score, and tumor size between the TSC1/TSC2 mutation group and the non-mutation group (all P>0.05), while there were significant differences in tumor number, extrahepatic metastasis, and PS score between the two groups (all P<0.05). The logistic regression analysis showed that TSC1/TSC2 gene mutation was positively correlated with the severity of HCC (odds ratio=1.706, P<0.05). The follow-up results showed that the TSC1/2 mutation group had a significantly lower survival rate than the non-mutation group, and there was a significant difference in 3-year mortality rate between the TSC1/2 mutation group and the non-mutation group (60.3% vs 38.6%, χ2=3.923,P<0.05). ConclusionTSC1/TSC2 gene mutation may predict the malignant progression of HCC in the early stage, and patients with TSC1/2 mutation tend to have poor prognosis. Targeted drug therapy for gene mutations may have a certain effect in delaying the progression of HCC.

ABSTRACT

Objective To investigate the rate and the population distribution of subjects with indeterminate result of HIV antibody test and to understand the relationships between the western blot(WB)banding patterns and HIV infection through follow-up reexamination. Methods Samples with indeterminate results of HIV antibody test were collected by Jiading Center for Disease Control and Prevention from 2013 to 2017. They were used for analysis of the source, the distribution of Western blotting band pattern and the follow-up results. Results Among 698 samples required to be re-tested for confirmation of HIV infection, 151(21.63%)showed indeterminate WB test results. There were 18 types of WB band in 151 HIV antibody-indeterminate samples. The most common band types, accounting for 79.47%, were p24, gp160, and gp160p24. One hundred(among 151)subjects were followed up and the success follow-up rate was 50.00%. Among them, 28(56.00%)samples were still with indeterminate results of HIV antibody, 11(22.00% turned to be negative and 11(22.00%)turned to positive. The follow-up confirmatory tests showed that 67.86% of the samples with p24 band were still with indeterminate results and 40.00% of the samples with gp160 band became HIV antibody-negative. The samples with one of the three band patterns of gp160gp120p24, gp160p24p17 and gp160gp120p66p51 all became HIV antibody-positive. Conclusion The detection rate of indeterminate HIV antibody results varies in different populations. Positive conversion rates with different WB band patterns are different. Follow-up of the populations with specific WB band patterns should be strengthened to detect HIV infection cases as early as possible.

ABSTRACT

@#Objective    To compare the short-term and long-term effects of minimally invasive esophagectomy (MIE) and traditional open esophagectomy (OE) in patients with stage T1b esophageal squamous cell carcinoma (ESCC). Methods    We retrospectively analyzed the clinical pathology data of 162 patients undergoing thoracic surgery at Northern Jiangsu People's Hospital from 2015 to 2018 whose pathological diagnosis was stage pT1b ESCC. According to the surgical approach, they were divided into MIE group and OE group. There were 55 males and 21 females in the OE group, with an average age of 63.3±5.6 years, and 60 males and 26 females in the MIE group, with an average age of 64.7±6.1 years. The preoperative, intraoperative and postoperative data of the two groups were compared and followed up. Survival data were compared using Kaplan-Meier and log-rank tests between the two groups, and Cox proportional hazard regression models were used to analyze prognostic factors. Results    Compared with the OE group, the intraoperative bleeding volume of the MIE group was less (119.8±70.0 mL vs. 210.5±136.2 mL, P<0.001), and the lymph nodes dissected during the operation were more (19.1±7.4 vs. 13.8±5.9, P<0.001), the rate of postoperative pulmonary infections was lower (9.3% vs. 21.1%, P=0.036), but the operation time was longer (240.0±52.4 min vs. 179.5±35.7 min, P<0.001). Twenty-one patients had lymph node metastasis, and the lymph node metastasis rate was 13.0%. At the end of the follow-up, 19 patients died, and the overall survival (OS) at 1 year, 3 years, and 5 years after operation were 97.5%, 88.8% and 82.9%, respectively; 31 patients had recurrence and metastasis, and the disease-free survival (DFS) rate at 1 year, 3 years, and 5 years after operation was 95.1%, 80.9% and 75.6%. There was no significant difference in OS and DFS between the two groups. Multivariate Cox regression analysis of OS found that lymph node metastasis, anastomotic fistula and chylothorax were independent risk factors for OS. Multivariate Cox regression analysis of DFS found that lymph node metastasis, anastomotic fistula, chylothorax, and vascular cancer thrombus were independent risk factors for OS. Conclusion    MIE can achieve the same long-term effects as OE, with less intraoperative bleeding, more lymph nodes dissected, and lower incidence of postoperative pulmonary infections, but it takes longer operation time.

ABSTRACT

@#Objective    To verify the feasibility of a self-designed magnetic anchoring and traction device (MATD) for assisting two-port video-assisted thoracoscopic esophagectomy. Methods    Three Beagle dogs were selected as animal models with age ranging from 1-6 years and weight ranging from 8-12 kg, and they underwent two-port video-assisted thoracoscopic esophagectomy after general anesthesia. We used the MATD to retract the esophagus to different directions, which assisted mobilizing esophagus, detecting the nerves along esophagus and dissecting paraesophagus lymph nodes. The operation time, blood loss and feasibility of the MATD were recorded. Results    With the aid of the MATD, we successfully retracted and mobilized the esophagus, detected the nerves and dissected the lymph nodes in three Beagle dog models. During the operation, the MATD provided sufficient and steady traction of esophagus to achieve a good exposure of the operative field, effectively decreasing the interference between working instruments. The MATD worked well. The mean operation time was 30 min, and the mean intraoperative blood loss was about 10 mL. Conclusion    It is effective to use the MATD to assist retracting esophagus during video-assisted thoracoscopic esophagectomy. The magnetic anchoring and traction technique can assist to expose the surgical field, decrease the interference between the working instruments and have the potential clinical application.

ABSTRACT

Objective To establish a multiplex nucleic acid assay for rapid detection of Echinococcus multilocularis, E. granulosus and E. shiquicus based on the recombinase-aided isothermal amplification assay (RAA) and to preliminarily assess its diagnostic efficiency. Methods The mitochondrial genomic sequences of E. multilocularis (GenBank accession number: NC_000928), E. granulosus (GenBank accession number: NC_044548) and E. shiquicus (GenBank accession number: NC_009460) were used as target sequences, and three pairs of primers were designed based on the RAA primer design principle and synthesized for the subsequent multiple RAA amplification. The genomic DNA of E. multilocularis, E. granulosus and E. shiquicus at different concentrations and the recombinant plasmids containing the target gene at various concentrations were amplified to evaluate the diagnostic sensitivity of the multiplex RAA assay, and the genomic DNA of E. multilocularis, E. granulosus, E. shiquicus, Taenia multiceps, T. saginata, T. asiatica, Dipylidium caninum, T. hydatigena, Toxocara canis, Fasciola hepatica, T. pisiformis, Mesocestoides lineatus and Cryptosporidiumn canis was detected using the multiplex RAA assay to evaluate its specificity. In addition, the reaction condition of the multiplex RAA assay was optimized, and was then employed to detect the tissues with echinococcosis lesions, simulated canine fecal samples and field captured fox fecal samples to examine its application values. Results The multiplex RAA assay was effective to specifically amplify the mitochondrial gene fragments of E. multilocularis, E. granulosus and E. shiquicus within 40 min at 39 °C, with sequence lengths of 540, 430 bp and 200 bp, respectively. This multiplex RAA assay showed the minimum detection limits of 2.0, 2.5 pg/μL and 3.1 pg/μL for detection of the genomic DNA of E. multilocularis, E. granulosus and E. shiquicus, and presented the minimum detection limit of 200 copies/μL for detection of the recombinant plasmids containing E. multilocularis, E. granulosus and E. shiquicus target genes. This multiplex RAA assay was effective to simultaneously detect single and multiple infections with E. multilocularis, E. granulosus and E. shiquicus, but failed to amplify the genomic DNA of T. multiceps, T. saginata, T. asiatica, D. caninum, T. hydatigena, T. canis, F. hepatica, T. pisiformis, M. lineatus and C. canis. In addition, the optimized multiplex RAA assay was effective to detect all positive samples from the tissue samples with echinococcosis lesions, simulated canine fecal samples and field captured fox fecal samples, which was fully consistent with the detection of the single PCR assay. Conclusion A sensitive and specific multiplex nucleic acid assay for rapid detection of E. multilocularis, E. granulosus and E. shiquicus has been successfully established.

ABSTRACT

@#Objective    To introduce a new type thoracic vest designed according to the incision characteristics of female patients undergoing totally thoracoscopic cardiac surgery. Methods    Sixty-one female patients undergoing totally thoracoscopic cardiac surgery from February 2019 to May 2020 in our department were enrolled. All female patients had hypermastia and (or) mastoptosis which covered the incision. They were randomly divided into a research group (group A, n=32) and a control group (group B, n=29). The group A used the new type thoracic vest, while the group B used the traditional single shoulder belt. The degree of satisfaction, visual analogue scale (VAS) score 24 hours after the thoracic drainage tube removed, the average time-consuming of dressing change, dressing frequency and the incision infection rate were compared between two groups. Results    The degree of satisfaction in the group A was higher than that of the group B (P<0.001). The VAS scores of pain, average time-consuming of dressing change and dressing frequency in the group A were less or lower than those of the group B (P<0.001). There was no statistical difference in the incision infection rate between the two groups (P=0.214), but incision infection rate of the group A was lower than that of the group B. Conclusion    The new type thoracic vest seems to be more beneficial for patients than traditional single shoulder belt. It is easy to use, increases the psychological satisfaction of patients, reduces the pain and the incision infection and improves work efficiency, which is worthy of clinical application.

ABSTRACT

China is one of the countries with the highest incidence of esophageal cancer, which is still increasing year by year in recent years. Surgical treatment is the first choice for early and middle esophageal cancer. Surgeons have been exploring how to remove the tumor as completely as possible and reduce the trauma as far as possible. In recent years, with the rapid development of minimally invasive surgery and endoscopic technology, minimally invasive esophagectomy(MIE)has led the trend of radical surgery for esophageal cancer. At present, the mainstream minimally invasive surgery is thoracoscopic thoracoscopic(VATS)resection of esophageal cancer, which requires thoracotomy and anesthesia, resulting in large surgical trauma and more complications of postoperative circulatory respiratory system. Mediastinose-assisted esophagectomy(MAE), which eliminates a thoracotomy, is also an important part of MIE. Overseas MAE application started early, but the domestic development is relatively slow. This article summarizes the experience of different MAE surgical methods in China, and provides the basis for its promotion in China.

ABSTRACT

Objective:To evaluate the short-term precision and accuracy of bone mineral density (BMD) measured with quantitative CT (QCT) and dual-energy X-ray absorptiometry (DXA) in multi-centre clinical research with a European spine phantom (ESP).Methods:From January 2016 to April 2020, totally 40 CT scanners (12 Siemens from Germany, 12 Philips from Netherlands, 9 GE from US, 5 Toshiba from Japan, 2 United Imaging from China) and 53 DXA instruments (34 GE Lunar from US, 14 Hologic from US, 5 Medlink from France) used in multi-centre in China were enrolled. The CT equipment came from 31 centers and DXA equipment from 32 centers.Using Mindways QCT software, the ESP was scanned 10 times on each instrument with repositioning using standardized spine protocols with QCT and DXA. The BMD value of the three lumbar vertebrae with low, medium, high density and the mean BMD value were measured. Accuracy was assessed by comparing BMD values measured on each device with the actual value of the phantom. Short-term precision was calculated as the root-mean-square standard deviation (RMS-SD) and root-mean-square standard deviation coefficient of variation (RMS-%CV) for the repeated measurements. The repeated measures variance analysis was used to compare the differences in BMD between different devices.Results:The differences in BMD values were statistically significant among different CT and DXA devices.The ranges of the accuracy measured by different QCT devices were 1.20% to 7.60% for Siemens, -1.83% to 0.20% for Philips, 1.18% to 13.20% for GE, -0.12% to 3.55% for Toshiba, -1.65% to 6.32% for United Imaging, 6.59% to 21.34% for GE Lunar, -6.65% to 5.45% for Hologic, and -6.97% to -0.68% for Medlink, respectively. The RMS-%CV of all vertebral BMD values measured by QCT and DXA ranged from 0.38% to 3.85%. The RMS-SD of QCT was 0.54 to 2.45 mg/cm 3, of DXA was 0.009 to 0.037 g/cm 2. The RMS-%CV values of each vertebral body measured by different QCT and DXA devices decreased with the increase of BMD, while the RMS-SD values showed the opposite tendency. Conclusions:Based on ESP, the QCT and DXA devices have significant differences in lumbar spine BMD measurement. Comparing the measurement results among different devices requires cross-calibration. Overall, the accuracy and short-term precision are within a reasonable range, which can be used for clinical follow-up observation. The short-term precision error and accuracy error range of QCT in evaluating the density of ESP were slightly smaller than those of DXA.

ABSTRACT

Objective:To investigate the relationship between epicardial adipose tissue (EAT) thickness and left ventricular geometry in patients with obstructive sleep apnea syndrome (OSAS).Methods:Two hundred and twenty-one OSAS patients were enrolled consecutively from the First Hospital of Shanxi Medical University from January to December 2019. According to left ventricular mass index (LVMI) and relative wall thickness (RWT), OSAS patients were divided into 4 groups based on the left ventricular geometry: 110 with normal geometry (NG group), 56 with concentric remodeling (CR group), 32 with concentric hypertrophy (CH group), and 23 with eccentric hypertrophy (EH group). The patients were examineel by echocardiography, the left ventricular end diastolic diameter, LVMI, interventricular septal thickness, left ventricular posterior wall thickness, left ventricle ejcetion fraction, E/A were collected. Age, systolic blood pressure (SBP), diastolic blood pressure (DBP), apnea hypopnea index (AHI), nocturnal lowest oxygen saturation (Lowest-SaO 2), nocturnal mean oxygen saturation (Mean-SaO 2), the percentage of the time that oxygen desaturation below 90%(T90), oxygen desaturation index(ODI), triglyceride (TG), total cholesterol (TC), EAT thickness and the echocardiography parameters were compared among the four groups. The relationships between EAT thickness and the above-mentioned parameters and left ventricular geometry were analyzed by univariate and multivariate linear regressions. Results:①The higher EAT thickness was found in the CH group [(0.50±0.09)cm] and EH group [(0.46±0.07)cm] compared with the NG group [(0.33±0.11)cm] and CR group [(0.36±0.15)cm] (all P<0.05). In addition, age, SBP, DBP, AHI, ODI, T90, LVMI, RWT and E/A ratio were all significantly different among the groups (all P<0.05). ②Univariate linear regression analysis showed that EAT thickness was positively correlated with age, SBP, DBP, AHI, TG, TC and LVMI, RWT, left ventricular geometry, and negatively correlated with Mean-SaO 2 and Lowest-SaO 2. ③Multivariate linear regression analysis showed that EAT thickness was independently correlated with AHI, TG, TC and left ventricular geometry. Conclusions:EAT is independently related to abnormal left ventricular geometry, suggesting that EAT may be involved in the process of left ventricular remodeling.

ABSTRACT

Objective:To explore the application value of creatinine correction method in estimating 24 h urinary iodine excretion of healthy adults.Methods:Healthy adults(half males and half females) aged 18 to 59 yesrs old in Tangshan City were selected as the research subjects. Random urine within 1 d, morning urine and 24 h urine samples of 5 d in a row of all subjects were collected to detect urinary iodine and creatinine concentrations. Twenty-four hours urinary iodine excretion was estimated by creatinine correction formula [24 h urinary iodine excretion estimated value(μg/d) = urinary iodine/creatinine concentration ratio (μg/g Cr) × 24 h urinary creatinine excretion (g Cr/d)]. The estimated value of 24 h urinary iodine excretion obtained from random urine within 1 d and continuous 5 d morning urine corrected by creatinine were studied by the coefficient of variation, and compared with the measured value of 24 h urinary iodine excretion.Results:The coefficient of variation of the estimated 24 h urinary iodine excretion of random urine within 1 d ranged from 8.8% - 20.2%, with an average value of 13.1%; the coefficient of variation of 24 h urinary iodine excretion estimated value from continuous 5 d morning urine and the 24 h urinary iodine excretion measured value ranged from 4.7% - 17.2% and 4.0% - 10.4%, and the average values were 10.1% and 6.4%, respectively. In the detection of random urine within 1 d, there was no significant difference between the 24 h urinary iodine excretion estimated value of the first, second, third, and forth time random urine and the 24 h urinary iodine excretion measured value ( P > 0.05). In the detection of continuous 5 d morning urine, there were no significant differences in the 24 h urinary iodine excretion estimated value of the first, second, third, forth and fifth day compared with the 24 h urinary iodine excretion measured value on the same day, respectively ( P > 0.05). Conclusions:When the daily creatinine excretion is accurately known, the estimated 24 h urine iodine excretion obtained by the creatinine correction method can better reflect the actual 24 h urinary iodine excretion. Further study on prediction criteria of creatinine excretion suitable for Chinese people will help to better detect the iodine intake of corresponding individuals.

ABSTRACT

OBJECTIVE:To establish the metho d for the content determination of 8 nucleosides in wild and cultivated Pinellia ternate,and to conduct the difference analysis. METHODS :The contents of uracil ,uridine,inosine,xanthine,adenine, guanosine,β-thymidine and adenosine in 20 batches of P. ternate (wild product YS 1-YS8,cultivated product ZP 1-ZP12)were determined by HPLC method. Based on the contents of the above 8 nucleosides,cluster analysis ,principal component analysis (PCA),partial least squares analysis (OPLS-DA)were used to comprehensively evaluate the wild and cultivated P. ternata . RESULTS:The contents of uracil ,uridine,inosine,xanthine,adenine,guanosine,β-thymidine and adenosine in 20 batches of P. ternate were 0.02-0.24,0.01-0.24,0.06-0.37,0.02-0.14,0.04-0.22,0.14-0.42,0.01-0.09,0-0.32 mg/g,respectively. Cluster analysis,PCA and OPLS-DA showed that 8 batches of wild P. ternate (YS1-YS8)were clustered into one category ,and 12 batches of cultivated P. ternate (ZP1-ZP12)were clustered into one category. Main characteristic markers of wild P. ternate were guanosine,uridine,adenosine and adenine ,while the main characteristic markers of cultivated P. ternate were urinine ,xanthine, inosine,and β-thymidine. CONCLUSIONS:The method for the content determination of 8 nucleosides in P. ternate is established. Nucleosides as quality markers can effectively distinguish wild and cultivated P. ternata ,and the quality of the wild P. ternate was better than that of cultivated P. ternate .

ABSTRACT

Triptolide (TP), an active component of Tripterygium wilfordiiHook. f. (TWHF), has been widely used for centuries as a traditional Chinese medicine. However, the clinical application of TP has been restricted due to multitarget toxicity, such as hepatotoxicity. In this study, 28 days of oral TP administration (100, 200, or 400 μg·kg

ABSTRACT

Antiviral Oral Liquid is modified on the basis of Baihu Decoction in Treatise on Febrility Diseases by ZHANG Zhongjing and Qingwen Baidu Yin in Qing Dynasty, with effects in clearing toxic heat, repelling dampness and cooling blood. It is widely used in clinical treatment of common colds, influenza and upper respiratory tract infection, mumps, viral conjunctivitis and hand-foot-mouth disease, with a good clinical efficacy and safety. Based on a questionnaire survey of clinicians and a systematic review of study literatures on Antiviral Oral Liquid, the international clinical practice guidelines development method was adopted to analyze the optimal available evidences and expert experiences in the "evidence-based, consensus-based and experience-based" principles. The consensus was jointly reached by more than 30 multidisciplinary experts nationwide, including clinical experts of traditional Chinese and Western medicine in the field of respiratory diseases and infectious diseases, and methodological experts. In the study, literatures were retrieved based on clinical problems in the clinical survey as well as PICO clinical problems. The GRADE system was used for the classification and evaluation of evidence, and fully combined with clinical expert experience, so as to reach expert consensus by the nominal grouping method. This expert consensus recommended or suggested indications, usage and dosage, course of treatment, intervention time for treatment, and the safety and precautions of Antiviral Oral Liquid for treatment of influenza, and can provide reference for the rational use of this drug in clinical practice.
