ABSTRACT

Objective:To explore the incremental value of subtraction technique in evaluating the major features of liver reporting and data system version 2018 (LI-RADS v2018) on gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid (Gd-EOB-DTPA) enhanced MRI.Methods:The Gd-EOB-DTPA enhanced MRI of 117 pathologically verified hepatocellualr carcinoma(HCC) from 87 high-risk patients in Henan Provincial People′s Hospital from January 2019 to July 2020 was analyzed retrospectively. The major features of LI-RADS in arterial phase, portal venous phase, subtraction and combined images were evaluated including nonrim arterial phase hyperenhancement (Nonrim APHE), nonperipheral washout and enhancing capsule. The lesions were graded according to LI-RADS v2018. According to the lesion size (<20 mm, ≥20 mm) and T 1WI signal intensity (hypointensity, isointensity or hyperintensity), the patients were divided into different subgroups. Cochran′s Q test was used for the comparison of the detection rate of the major features of LI-RADS and the accurate diagnosis rate based on LR-5 as the diagnostic standard among multiple groups. McNemar test was used for the comparison between two groups. Results:For all HCC, hypointensity HCC and HCC ≥20 mm, the detection rate of Nonrim APHE (χ2=12.190, 12.500, 10.083, all P<0.001) and the accurate diagnosis rate of HCC (χ2=14.450, 12.500, 10.083, all P<0.001) of subtraction images from arterial phase were significantly higher than that of arterial images. For HCC<20 mm, the detection rate of Nonrim APHE combined with arterial phase images was significantly higher than that in arterial phase images (χ2=5.143, P=0.016). For all HCC and isointensity or hyperintensity HCC, the detection rate of nonperipheral washout combined with portal venous phase images was higher than that in portal venous phase images (χ2=7.111, 6.125, P=0.004, 0.008). The detection rate of enhancing capsule of subtraction images from portal venous phase was higher than that of portal venous phase images in all groups (all P<0.017). The accurate diagnosis rate of subtraction images from portal venous phase in all HCC and HCC≥20 mm was higher than that in portal venous phase images (χ2=6.722, 6.750, P=0.008, 0.006). The accurate diagnosis rate of LR-5 in all groups using subtraction images from arterial phase and portal venous phase was higher than that of MRI images (all P<0.013). Conclusion:For Gd-EOB-DTPA dynamic enhanced MRI, subtraction images from arterial phase and portal venous phase are better than arterial phase and portal venous phase images in displaying Nonrim APHE, nonperipheral washout and enhancing capsule, which can improve the LI-RADS classification of HCC.

ABSTRACT

Objective:To understand the current situation of water improvement and the prevalence of dental fluorosis in children aged 8 to 12 in drinking-water-type endemic fluorosis (referred to as drinking-water-type fluorosis) areas in Inner Mongolia Autonomous Region (referred to as Inner Mongolia), and to evaluate the effectiveness of prevention and control measures, and provide a basis for timely adjustment of prevention and control strategies.Methods:In 2019, a cross-sectional survey was conducted to investigate the situation of water improvement and water fluoride content in all villages of 85 drinking-water-type fluorosis banners (counties) in Inner Mongolia, and all the children aged 8 to 12 were examined for dental fluorosis.Results:Among the 9 623 disease affected villages in the region, the water improvement projects were completed in 8 547 villages, and the water improvement rate was 88.82%. There were 7 145 water improvement villages whose water fluoride content met the national drinking water hygiene standard, which accounted for 83.60% (7 145/8 547) of the total villages with water improvement projects. A total of 118 857 children aged 8 to 12 were examined, and 9 123 cases of dental fluorosis were detected. The detection rate of dental fluorosis was 7.68%, which was lower than the upper limit of the dental fluorosis detection rate of fluorosis area standards (30%).Conclusions:The accomplishment rate of water improvement projects in drinking-water-type fluorosis areas of Inner Mongolia is high, and the condition of children's dental fluorosis has been effectively controlled. However, it is still necessary to strengthen the water quality monitoring, improve the qualified rate of water improvement projects, and effectively implement various comprehensive prevention and control measures.

ABSTRACT

Objective:to investigate the effect of maximum transurethral cystectomy ((TURBT)) before radical cystectomy on the prognosis of patients with multiple bladder tumors.Methods:the clinical data and follow-up records of 90 patients with multiple bladder tumors treated in our hospital from August 2010 to August 2018 were analyzed retrospectively. There were 72 males and 18 females. The age ranged from 20 to 84 years old, with an average of (64.6 ±11.7) years. There were 50 cases of age <60 years old and 40 cases of ≥60 years old. The median age of male was 68 years old and that of female was 69 years old. The diameter of Tumor was ≥3 cm in 52 cases and <3 cm in 38 cases. There were 53 cases with 2 lesions and 37 cases with more than 2 lesions. According to the extent of TURBT resection, 55 patients (61.1%) were divided into maximum TURBT group, 42 males and 13 females, with an average age of (56.2±12.0) years. Tumor diameter ≥3 cm(n=29) and <3 cm(n=26). There were 35 cases (38.9%) in the non-maximal TURBT group, including 30 males and 5 females, with an average age of (59.8±13.4) years. In the non-maximum TURBT group. The diameter of tumor was ≥3 cm in 23 cases and <3 cm in 12 cases. There was no significant difference in preoperative data between the two groups ( P > 0.05). In the maximum TURBT group, all the tumors visible to the naked eye were completely removed, and the tissues were taken from the base and surrounding mucosa for pathological examination. Diagnostic TURBT group: multiple tumors in the bladder were found during the operation, the surface was rough, and there were no ureteral orifices on both sides. Samples of ureteral orifice and surrounding mucosal tissues were taken for biopsy, and the bladder tumor was not completely removed. Radical cystectomy was performed in both groups. The relationship between two different surgical methods and clinicopathological factors was analyzed. After that, the recurrence-free survival time (RFS) and overall survival time (OS) of patients were analyzed by Kaplan-Meier method, and the statistical difference of survival curve was analyzed by Log-rank method. Univariate Log-rank and multivariate Cox regression analysis were used to analyze the influencing factors of RFS and OS. Results:In this study, 90 cases of radical cystectomy were completed successfully. The postoperative follow-up time was 7-60 months, 1 case lost follow-up, and the median follow-up time was 30 (15-46) months. There was no significant difference in all data between maximum TURBT group and diagostic TURBT group ( P>0.05). Urethral recurrence occurred in 6 (6.7%) cases and pelvic recurrence in 9 (10%) cases after RC. 15 (16.7%) cases died, of which 8 cases died of postoperative pelvic recurrence, 3 cases died of myocardial infarction, 2 cases died of bone metastasis and 2 cases died of pulmonary metastasis. The results of Kaplan-Meier method showed that the 1-, 3-and 5-year overall survival rates of patients with RC after maximum TURBT were 96.67%, 86.05% and 80.86%, respectively, and the 1-, 3-and 5-year relapse-free survival rates were 89.97%, 76.93% and 71.41%, respectively. Univariate Log-rank results showed that pathological stage ( P=0.018), urethral recurrence ( P<0.01), pelvic recurrence ( P<0.01) and maximum TURBT ( P<0.01) were the risk factors of OS and RFS. The risk of death in patients with pelvic recurrence was higher than that in patients without pelvic recurrence ( HR=41.850, 95% CI 12.597-139.036, P<0.01). The risk of death in patients with urethral recurrence was higher than that in patients without urethral recurrence ( HR=8.128, 95% CI 1.551-42.606, P<0.01). The risk of death in patients with RC after maximum TURBT was lower than that in patients with diagnostic TURBT ( HR=0.164, 95% CI 0.036-0.746, P<0.01). Among them, there were only 2(3.9%) pelvic recurrence in patients with maximum TURBT combined with RC, 7(6.1%) pelvic recurrence and 6(6.7%) urethral recurrence in patients without maximum TURBT combined with RC, and there was significant difference between patients without maximum TURBT and patients without maximum urethral recurrence. Multivariate Cox analysis showed that urethral recurrence ( HR=8.128, 95% CI 1.551-42.606, P=0.013, P<0.01) and pelvic recurrence ( HR=41.850, 95% CI: 12.597-139.036, P<0.01) were independent risk factors for OS, and urethral recurrence ( HR=18.637, 95% CI 5.443-63.817, P<0.01) and pelvic recurrence ( HR=22.94, 95% CI 8.635-60.973, P<0.01) were independent risk factors for RFS. The maximum TURBT was the independent protective factor of OS ( HR=0.164, 95% CI 0.036-0.746 P<0.01) and RFS ( HR=0.153, 95% CI 0.048-0.493, P<0.01). Conclusions:For patients with multiple bladder tumors, radical cystectomy with maximum TURBT before radical cystectomy might reduce urethral and pelvic recurrence after radical cystectomy, and might improve the prognosis of patients with multiple bladder cancer. Maximum TURBT is an independent protective factor for OS and RFS. Urethral recurrence and pelvic recurrence are independent risk factors for OS and RFS.

ABSTRACT

Objective:To investigate the application value of computed tomography (CT) examination of lymph node short diameter in evaluating left recurrent laryngeal nerve lymph node metastasis in thoracic esophageal squamous cell carcinoma.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 628 patients with thoracic esophageal squamous cell carcinoma who were admitted to 2 medical centers (236 cases in the Sun Yat-sen University Cancer Center and 392 cases in the Affiliated Cancer Hospital of Zhengzhou University) from October 2009 to December 2016 were collected. There were 462 males and 166 females, aged from 38 to 85 years, with a median age of 62 years. Observation indicators: (1) operation status, dissection and metastasis of left recurrent laryngeal nerve lymph node; (2) efficacy of CT examination of the left recurrent laryngeal nerve lymph node short diameter in evaluating postoperative lymph node metastasis; (3) determination of the optimal cut-off value; (4) examination results using different diagnostic criteria. Measurement data with skewed distribution were represented as M (range). Count data were described as absolute numbers or percentages. The area under curve (AUC) of receiver operating characteristic curve (ROC) was used to estimate the efficiency of detection methods. The maximum value of Youden index corresponded to the optimal cut-off point. Results:(1) Operation status, dissection and metastasis of left recurrent laryngeal nerve lymph node: among the 628 patients, there were 572 cases undergoing two-field lymph node dissection while 56 cases undergoing three-field lymph node dissection, there were 408 cases undergoing minimally invasive surgery while 220 cases undergoing open surgery. Sixty of 628 patients had left recurrent laryngeal nerve lymph node metastasis. A total of 1 666 left recurrent laryngeal nerve lymph nodes were dissected from the 628 patients, among which 75 were metastatic lymph nodes, with a metastasis rate of 4.502%(75/1 666). (2) Efficacy of CT examination of the left recurrent laryngeal nerve lymph node short diameter in evaluating postoperative lymph node metastasis: the AUC of CT examination of the left recurrent laryngeal nerve lymph node short diameter in predicting postoperative lymph node metastasis was 0.854 (95% confidence interval as 0.792 to 0.916, P<0.05). (3) Determination of the optimal cut-off value: the Youden indices were 0.556, 0.384, 0.258, 0.063 and 0.003 respectively when using 5 mm, 6 mm, 7 mm, 8 mm, 9 mm or 10 mm as the optimal cut-off value for CT examination of the left recurrent laryngeal nerve lymph node short diameter. The short diameter as 5 mm was the optimal cut-off value for CT examination of the left recurrent laryngeal nerve lymph node short diameter. (4) Examination results using different diagnostic criteria: the sensitivity, specificity, accuracy, positive predictive value, negative predictive value, cases being missed diagnosis were respectively 66.3%, 92.3%, 89.5%, 46.3%, 96.0%, 20 and 5.0%, 99.8%, 90.7%, 75.0%, 90.9%, 57 when using short diameter ≥5 mm or ≥10 mm in CT examination of the left recurrent laryngeal nerve lymph node as the diagnostic criteria for left recurrent laryngeal nerve lymph node metastasis of thoracic esophageal squamous cell carcinoma. Conclusions:CT examination of lymph node short diameter can be used to evaluate left recurrent laryngeal nerve lymph node metastasis in thoracic esophageal squamous cell carcinoma. The sensitivity, specificity and accuracy is preferable when using short diameter ≥5 mm in CT examina-tion of the left recurrent laryngeal nerve lymph node as the diagnostic criteria for left recurrent laryngeal nerve lymph node metastasis of thoracic esophageal squamous cell carcinoma.

ABSTRACT

To investigate the effect of captopril on the dentin bonding durability of self-etch adhesive. Different concentrations of captopril ethanol solutions or captopril ethanol/water solutions were prepared to pretreat dentin as primer for the self-etch adhesives. The surface morphology of the dentin was observed with scanning electron microscopy (SEM). Based on the morphology analysis, the pretreatment condition was selected and two self-etch adhesives were employed to evaluate the improvement effect of the captopril pretreatment on the dentin bonding durability. : SEM showed that the pretreatment of captopril ethanol solutions and captopril ethanol/water solutions were able to remove the smear lay and partially expose collagen matrix. According to the SEM results, the pretreating condition of captopril ethanol/water solution with the pretreating time of was selected for further dentin bonding study. For Clearfil SEBOND system, the immediate bonding strength increased from to  (0.05]. For Clearfil S BOND system, there was no significant difference in the immediate bonding strength between the experimental group [(4.07) MPa] and the control group[(4.11) MPa]. But after one-year aging, the bonding strength of the experimental group was higher than that of the control group <0.05]. : The pretreatment with captopril ethanol/water solution increases the dentin bonding strength of the self-etch adhesive systems and also improves the bonding durability.

ABSTRACT

Objective:To investigate the value of serum miR-143 level combined with MRI in predicting the early response to concurrent chemoradiotherapy (CCRT) in cervical cancer.Methods:A total of 85 patients with pathologically confirmed cervical cancer underwent conventional MRI, intravoxel incoherent motion diffusion-weighted imaging (IVIM-DWI), and dynamic contrast-enhanced MRI (DCE-MRI) before CCRT. The biopsy tissues and serum samples were collected. The differential expression of miRNA in the biopsy tissues was determined by microarray chip. The expression level of miR-143 in the serum samples was analyzed by qRT-PCR. All patients were divided into the non-residual and residual tumor groups according to post-treatment MRI. Pre-treatment clinical factors, MRI parameters and miR-143 between two groups were statistically analyzed by the univariate and multivariate analyses. The optimal thresholds and predictive performance for post-treatment incidence of residual tumors were estimated by drawing the ROC curve.Results:At one month after CCRT, there were 52 patients in the non-residual tumor group and 33 patients in the residual tumor group. In the residual tumor group, pre-treatment FIGO staging, apparent diffusion coefficient (ADC), D and V e were significantly higher (all P<0.05), whereas K trans value was significantly lower ( P<0.001) when compared to those in the non-residual tumor group. The miRNA array analysis showed that there were 16 miRNAs with differential expression levels between two groups (all P<0.05). Among them, the increase of miR-143 was the most significant in the residual tumor group. Compared with the residual tumor group, the expression level of serum miR-143 was significantly down-regulated in the non-residual tumor group ( P=0.002). Compared with the SiHa cells, the expression level of miR-143 in the SiHa-R cells was significantly up-regulated ( P<0.05). Multivariate analysis showed that only miR-143, D, K trans and V e were the independent prognostic factors. The combination of multi-parametric MRI and miR-143 exhibited the highest predictive performance (AUC=0.975), with a sensitivity of 84.8% and a specificity of 96.2%. Conclusion:The combination of multi-parametric MRI with miR-143 further improves the predictive performance for residual tumors after CCRT, which contributes to the personalized treatment of cervical cancer.

ABSTRACT

Coronavirus disease 2019 (COVID-19) is now pandemic worldwide and has heavily overloaded hospitals in Wuhan City, China during the time between late January and February. We reported the clinical features and therapeutic characteristics of moderate COVID-19 cases in Wuhan that were treated via the integration of traditional Chinese medicine (TCM) and Western medicine. We collected electronic medical record (EMR) data, which included the full clinical profiles of patients, from a designated TCM hospital in Wuhan. The structured data of symptoms and drugs from admission notes were obtained through an information extraction process. Other key clinical entities were also confirmed and normalized to obtain information on the diagnosis, clinical treatments, laboratory tests, and outcomes of the patients. A total of 293 COVID-19 inpatient cases, including 207 moderate and 86 (29.3%) severe cases, were included in our research. Among these cases, 238 were discharged, 31 were transferred, and 24 (all severe cases) died in the hospital. Our COVID-19 cases involved elderly patients with advanced ages (57 years on average) and high comorbidity rates (61%). Our results reconfirmed several well-recognized risk factors, such as age, gender (male), and comorbidities, as well as provided novel laboratory indications (e.g., cholesterol) and TCM-specific phenotype markers (e.g., dull tongue) that were relevant to COVID-19 infections and prognosis. In addition to antiviral/antibiotics and standard supportive therapies, TCM herbal prescriptions incorporating 290 distinct herbs were used in 273 (93%) cases. The cases that received TCM treatment had lower death rates than those that did not receive TCM treatment (17/273 = 6.2% vs. 7/20= 35%, P = 0.0004 for all cases; 17/77= 22% vs. 7/9= 77.7%, P = 0.002 for severe cases). The TCM herbal prescriptions used for the treatment of COVID-19 infections mainly consisted of Pericarpium Citri Reticulatae, Radix Scutellariae, Rhizoma Pinellia, and their combinations, which reflected the practical TCM principles (e.g., clearing heat and dampening phlegm). Lastly, 59% of the patients received treatment, including antiviral, antibiotics, and Chinese patent medicine, before admission. This situation might have some effects on symptoms, such as fever and dry cough. By using EMR data, we described the clinical features and therapeutic characteristics of 293 COVID-19 cases treated via the integration of TCM herbal prescriptions and Western medicine. Clinical manifestations and treatments before admission and in the hospital were investigated. Our results preliminarily showed the potential effectiveness of TCM herbal prescriptions and their regularities in COVID-19 treatment.

ABSTRACT

Objective:To analyze the application of functional residual capacity (FRC)-guided optimal positive end-expiratory pressure (PEEP) in pulmonary retention in patients with acute respiratory distress syndrome (ARDS), and to explore the correlation between FRC and trans-pulmonary pressure and their predictive value for prognosis.Methods:Seventy-eight ARDS patients on mechanical ventilation admitted to department of critical care medicine of the First Affiliated Hospital of Jinzhou Medical University from March 2018 to May 2019 were enrolled. According to random number table method, the patients were divided into experimental group and the control group. PEEP of all patients were gradually increased in recruitment after fully sedation and analgesia. The best PEEP was set by monitoring FRC in the experimental group, and by monitoring maximum oxygen in the control group set. The differences before and after 30 minutes and 2 hours recruitment manoeuvres in dynamic compliance (Cdyn), oxygenation index (PaO 2/FiO 2), and mechanical power (MP) were compared between the two groups. Pearson method was used to analyze the correlation between FRC and trans-pulmonary pressure. The predictive value of FRC and trans-pulmonary pressure for 28-day mortality in patients with ARDS was analyzed by receiver operating characteristic (ROC) curve. Results:The optimal PEEP was (16.24±1.57) cmH 2O (1 cmH 2O = 0.098 kPa) in the experimental group and (14.11±1.15) cmH 2O in the control group in recruitment maneuvres, with statistically significant difference between the two groups ( t = 5.678, P = 0.000). Pearson correlation analysis showed that there was a significant correlation between FRC and trans-pulmonary pressure in ARDS patients ( r = 0.759, P = 0.000). Cdyn and PaO 2/FiO 2 in the experimental group were higher than the control group at 30 minutes and 2 hours after recruitment maneuvres [Cdyn (mL/cmH 2O): 61.16±3.55 vs. 58.54±5.25, 58.59±2.82 vs. 56.86±3.40; PaO 2/FiO 2 (mmHg, 1 mmHg = 0.133 kPa): 245.27±14.86 vs. 239.00±5.34, 192.25±5.11 vs. 188.86±5.07], MP was lower than the control group (J/min: 16.32±1.11 vs. 17.05±1.22, 15.22±1.25 vs. 17.03±1.50), the difference was statistically significant (all P < 0.05). The ROC curve analysis showed that both FRC and trans-pulmonary pressure had predictive value for the 28-day mortality of ARDS patients, and the area under the ROC curve (AUC) was 0.868, and 0.828 respectively (both P < 0.01). Conclusions:Measuring FRC in patients with ARDS during recruitment maneuvres can guide optimal PEEP. FRC was significantly correlated with trans-pulmonary pressure, and both of them had predictive value for 28-day mortality in ARDS patients.

ABSTRACT

In the 19th century, modern stomatology education were introduced into China with the impact of the west medicine and education. The apprenticeship of modern stomatology education were carried out by missionaries firstly, and then changed to dental schools established by the missionaries or foreigners, which was replaced partly by local Chinese dentists later and improved the development of modern Chinese stomatology education preliminarily.

ABSTRACT

Objective@#To compare the difference in imaging and clinical effects between gap balance technique and measured resection technique in total knee arthroplasty (TKA).@*Methods@#We recruited 300 patients undertaking TKA from July 2014 to July 2016. TKA were performed by using gap balance technique or measured resection technique randomly. The intraoperative rotation of femoral prosthesis, changes of joint line, osteotomy volume, preoperative and postoperative KSS score, WOMAC score, VAS and ROM were compared between the two groups.@*Results@#A total of 292 patients were included in the present study, and 248 patients were successfully followed up for 2 years. The operation duration of the gap balance group was 65.9±14.1 min, which was significantly less than that of the measured osteotomy group 70.5±16.5 min (t=2.36, P=0.02). The rotation angle α of the femoral prosthesis measured on CT scan postoperative in gap balance group was 0.67°±1.71°, which was significantly smaller than that of the measured resection technique group 1.25°±2.53° (t=2.12, P=0.03). The external rotation angle β between the osteotomy plate and femoral posterior condyle line in the gap balance group was 1.25°±1.26°, which was significantly greater than that of the measured resection technique 0.28°±0.19° (t=6.57, P<0.01). The bone cut volume of femoral medial posterior condyle in gap balance group 9.85±1.37 mm showed a statistically difference (t=2.02, P=0.04) compared with that of the measured osteotomy group 9.52±1.19 mm. The KSS score was 83.8±10.2 in the gap balance group after 1 month. It was superior to the measured resection technique group of 80.5±9.4 with statistical significance (t=2.65, P=0.01). The knee ROM was 101.7°±12.7° in the gap balance group at 1 month after surgery, which was better than that in the measured resection technique group 98.2°±11.8° (t=2.25, P=0.03).@*Conclusion@#The axis of the femoral prosthesis was more consistent with STEA in the gap balance group of TKA. The gap balance group had better ROM and KSS functional scores at the first month after surgery. However, there was no statistical difference in knee function at the 2-year follow-up between the two groups.

ABSTRACT

Objective To evaluate the effect of PAD bundle in mechanically ventilated patients for preventing delirium. Methods Two hundred and forty three patients with mechanical ventilation who were admitted in ICU from January 2015 to February 2018 were divided into two groups according to the method of random number table. The patients in the control group(120 cases) received routine nursing care. The patients in the experimental group(123 cases) received the PAD bundle on the basis of routine nursing care. The scores of Richards Campbell Sleep Questionnaire(RCSQ), the doses of sedatives and analgesics, incidence of delirium, duration of delirium, ventilator time, ICU length of stay and the 28-day ICU mortality were compared between the two groups. Results The incidence of delirium, duration of delirium, ventilator time, ICU length of stay was 23.58%(29/123), (2.83±1.20) d, (153.07±55.61) d, (7.88± 2.89) d in the experimental group, 40.00%(48/120), (4.02 ± 1.99) d, (170.90 ± 63.51) d, (10.13 ± 3.41) d in the control group, and there was significant difference between the two groups (χ2=8.298, Z=2.840, 2.276, 5.325, P <0.01 or 0.05). The total score of RCSQ was (55.23 ± 17.89) points in the experimental group, (51.86±16.45) points in the control group, and there was significant difference between the two groups(Z=5.654, P<0.05). There was no significant difference in 28-day ICU mortality between the two groups (P>0.05). Conclusions The PAD bundle can decrease the incidence of delirium, the duration of delirium and improve prognosis of the patients with mechanical ventilation.

ABSTRACT

Objective In this paper, the extraction process of Xiaozhong-Zhitong granule (XZG) was investigated. Methods In Process 1, the Panax notoginseng (Burk.) F.H.Chen was extracted with other drugs, and in the process 2, the Panax notoginseng (Burk.) F.H.Chen was crushed and directly used as medicine. Rats were randomly divided into blank group, process 1 group, process 2 group and mixture group.The sample concentration of the process 1 group 1 for the stomach was 2.07 g/ml, and the sample concentration of the process 2 group 1 for the stomach was 1.06 g/ml, and the sample concentration of the mixture group for the stomach was 0.015 g/ml, and blank group gavaged equal volume saline. Anti-inflammatory and analgesic effects of acetic acid writhing test, hot plate test, auricle swelling test and egg white-induced plantar swelling test were evaluated. Results Compared with the blank group after 1, 2, 3, and 4 h after administration, the average writhing number of the mice in the process group 1 and the process 2 group (35.50% ± 8.06%, 35.00% ± 7.63%vs. 47.00% ± 1.45%) significantly decreased (P<0.01), and the auricular swelling degree (46.31% ± 22.25%, 45.41% ± 21.43% vs. 73.89% ± 15.55%) significantly decreased. And compared with the blank group after 0.5, 1, 2, and 4 h after inflammation, the percentage of pain threshold in the first group and the second group increased (P<0.01). While there was no significant difference in the inhibition rate of paw swelling in each group (P>0.05). Conclusions The design of extraction process of XZG was reasonable; when treating swelling and pain, it was better to put the powder of Panax notoginseng (Burk.) F.H.Chen in XZG.

ABSTRACT

Objective To explore the changes and clinical significance of transmural dispersion of repolarization (TDR) in patients with hypertrophic cardiomyopathy (HCM). Methods Seventy-two patients with HCM (observation group) and 72 healthy subjects (control group) in Shengjing Hospital of China Medical University were selected from January 2015 to October 2017. The 12-lead conventional electrocardiogram was performed on enrolled personnel in 2 groups to measure T-peak T-end (TpTe), correct the QT interval (QTc), QT interval dispersion (QTd) and TpTe/QTc. The observation group underwent 24 h dynamic electrocardiography. The patients were divided into ventricular arrhythmia subgroup and non- ventricular arrhythmia subgroup according to the results of 24 h dynamic electrocardiography, and the TpTe, QTc, QTd and TpTe/QTc were compared. Results The TpTe, QTc, QTd and TpTe/QTc in observation groups were significantly higher than those in control group:(112.5 ± 11.2) ms vs. (105.6 ± 9.2) ms, (396.5 ± 13.5) ms vs. (385.3 ± 12.5) ms, (36.5 ± 6.4) ms vs. (32.4 ± 5.4) ms and 0.289 ± 0.016 vs. 0.262 ± 0.015, and there were statistical differences (P<0.05). In observation group, the 24 h dynamic electrocardiogram result showed that 47 patients had ventricular arrhythmia (ventricular arrhythmia subgroup) and 25 patients had not ventricular arrhythmia (non-ventricular arrhythmia subgroup). The TpTe, QTc, QTd and TpTe/QTc in ventricular arrhythmia subgroup were significantly higher than those in non-ventricular arrhythmia subgroup: (114.4 ± 14.5) ms vs. (110.3 ± 12.2) ms, (402.5 ± 15.2) ms vs. (392.0 ± 12.1) ms, (37.5 ± 6.2) ms vs. (35.4 ± 6.5) ms and 0.292 ± 0.016 vs. 0.285 ± 0.015, and there were statistical differences (P<0.05). Conclusions The values of TpTe, QTc, QTd and TpTe/QTc reflect the increase of transmural dispersion of repolarization in patients with HCM, and have a certain predictive effect on ventricular arrhythmia.
