ABSTRACT

Objective:To explore superior mediastinal lymph node zoning of thyroid cancer for accurate anatomical definition as a reference for surgical access. Methods:A method for zoning superior mediastinal lymph nodes for thyroid cancer was proposed. From Sep 2018 to Nov 2019, 36 cases of thyroid cancer with superior mediastinal lymph nodes metastases were reviewed. The diagnosis, surgical approaches, pathology, characteristics of lymph node metastasis, complications and follow-up results were analyzed.Results:The superior mediastinal lymph nodes were grouped into 10 areas: 1, 2Ra, 2Rb, 2La, 2Lb, 3A, 3P, 4R, 4La and 4Lb. According to the location of the superior mediastinum metastatic lymph nodes, direct vision approach through the neck incision, laparoscope-assisted approach, thracoscepy, laparoscope-assisted combined with thrascopy approach or conventional median sternotomy was performed for regional lymph node dissection. The average follow-up time was (10±4) months. No residual or recurrence of tumor in superior mediastinal area was found.Conclusions:The zoning of the superior mediastinal lymph nodes in thyroid cancer can be used as a guide for surgical approach to lymph node dissection .

ABSTRACT

Objective:To evaluate the perioperative safety of pancreaticoduodenectomy(PD)in elderly patients.Methods:Clinical data of 152 patients undergoing PD in Beijing Hospital between 2016 and 2019 were retrospectively analyzed.According to the age, patients were divided into the elderly group(age≥65 years)and the non-elderly group(age<65 years). The perioperative and postoperative parameters were compared between the two groups.Results:There was no significant difference in the operative time, intraoperative blood loss and intraoperative urine output between the elderly group and the non-elderly group(352.7±69.5)min vs.(359.0±94.4)min, (708.7±672.7) vs.(662.6±896.7)ml and(875.8±497.3)ml vs.(1010.6±568.2)ml, all P>0.05). The perioperative mortality, postoperative complications(Clavien-Dindo classification ≥ grade Ⅲ)and reoperation rate had no significant difference between elderly group and the non-elderly group(6.1% vs.1.2%, 21.2% vs.19.8%, 10.6% vs.8.1%, respectively, χ2=1.487, 0.048 and 0.272, all P>0.05). The incidences of operation-related complications, cardiovascular or cerebrovascular adverse events in elderly group were comparable to non-elderly group( P>0.05). The postoperative hospital stay had no significant difference between the elderly group and the non-elderly group[(28±19)d vs.(27±18)d, P>0.05]. Conclusions:PD is safe in elderly patients.Age is not a contraindication to pancreaticoduodenectomy.The comprehensive systemic evaluation, intraoperative delicate operation and enhanced perioperative management are necessary in the elderly patients undergoing PD.

ABSTRACT

Objective:To compare the curative efficacy in the treatment of humeral surgical neck fractures between open reduction and locking plating versus closed reduction and interlocking intramedullary nailing.Methods:From July 2018 to July 2020, 60 patients with humeral surgical neck fracture were treated at Department of Orthorpaedic Trauma, Jiangmen Wuyi Hospital of Traditional Chinese Medicine. They were 24 males and 36 females, aged from 40 to 70 years and injured at the left side in 35 cases and at the right side in 25 ones. Of them, 30 underwent open reduction and locking plating (open group) and the other 30 closed reduction and interlocking intramedullary nailing (closed group). The 2 groups were compared in terms of operation time, intraoperative blood loss, surgical incision length, fracture healing time, Neer shoulder function scoring 3 months after surgery, and postoperative complications.Results:There were no statistically significant differences between the open and closed groups in preoperative general data, showing they were comparable ( P>0.05). The length of surgical incision [(5.2±1.1) cm], operation time [(34.3±12.7) min], intraoperative blood loss [(52.5±7.3) mL] and fracture healing time [(9.2±1.5) weeks] in the closed group were significantly better than those in the open group [(11.1±2.5) cm, (69.4±21.4) min, (123.5±5.2) mL and (14.2±3.4) weeks)] ( P<0.05). The excellent and good rate by Neer shoulder function scoring at 3 months after operation in the closed group (93.3%, 28/30) was significantly higher than that in the open group (66.7%, 20/30) ( P<0.05). There were no postoperative complications in either group. Conclusion:In the treatment of humeral surgical neck fractures, the curative efficacy of closed reduction and interlocking intramedullary nailing is better than that of open reduction and locking plating.

ABSTRACT

Spinal cord injury is a common clinical disease secondary to spinal cord fractures that causes patients with motor and sensory dysfunction or even paralysis. In recent years, exosomes have participated in the occurrence and development of various diseases as nanometer-sized cell particles, and have received extensive attention. Exosomes derived from spinal cord tissue cells during spinal cord injury affect the injury process and tissue repair. In addition, exosomes as a new treatment for spinal cord injury have been widely studied. The authors document the mechanisms of various exosomes from spinal cord tissue and the repair effects of various cell-derived exosomes in spinal cord injury, in order to deepen the understanding of the role of exosomes in spinal cord injury and provide new ideas for studying the course and treatment of spinal cord injury.

ABSTRACT

Objective:To investigate whether SKA1 is a key molecule regulating malignant proliferation of liver cancer, and further explore its mechanism to provide molecular theoretical basis for subsequent targeted therapy.Methods:The data of liver cancer from TCGA database were analyzed by bioinformatics technology. The expression of SKA1 in liver cancer was analyzed. At the same time, we also analyzed the relationship between the expression of SKA1 and the prognosis of patients with liver cancer. The hepatoma cell line overexpressing SKA1 was constructed by liposome-mediated cell transfection technique, and the effect of SKA1 on the proliferation of hepatoma cells was further tested by CCK-8 and plate cloning assay. At the same time, we found that E2F1 is also highly expressed in liver cancer, using bioinformatics technology to analyze the correlation between SKA1 and E2F1 expression, further detecting the binding site of E2F1 in the SKA1 promoter region, and using dual luciferase technology to detect E2F1 against SKA1. Transcriptional activation.Results:KA1 was highly expressed in liver cancer tissues, and the overall survival rate of liver cancer patients with high SKA1 expression was 49.8%, lower than that of patients with low SKA1 expression, showing a negative correlation. E2F1 is also highly expressed in liver cancer tissues, and the survival time of patients with liver cancer with high E2F1 expression is significantly lower than that in the low expression group, which was negatively correlated with poor prognosis. SKA1 overexpression could increase the proliferation ability of liver cancer cells by nearly 50%. SKA1 is regulated by the E2F1 transcription factor, and the E2F1 transcription factor is combined with the SKA1 promoter to transcriptionally activate the expression of SKA1 in liver cancer cells.Conclusion:E2F1 transcriptional activation of SKA1 promotes proliferation of hepatoma cells, leading to poor prognosis in patients with liver cancer

ABSTRACT

BACKGROUND@#Shenyankangfu Tablet (SYKFT) is a Chinese patent medicine that has been used widely to decrease proteinuria and the progression of chronic kidney disease.@*OBJECTIVE@#This trial compared the efficacy and safety of SYKFT, for the control of proteinuria in primary glomerulonephritis patients, against the standard drug, losartan potassium.@*DESIGN, SETTING, PARTICIPANTS AND INTERVENTION@#This was a multicenter, double-blind, randomized, controlled clinical trial. Primary glomerulonephritis patients, aged 18-70 years, with blood pressure ≤ 140/90 mmHg, estimated glomerular filtration rate (eGFR) ≥ 45 mL/min per 1.73 m@*MAIN OUTCOME MEASURES@#The primary outcome was change in the 24-hour proteinuria level, after 48 weeks of treatment.@*RESULTS@#A total of 735 participants were enrolled. The percent decline of urine protein quantification in the SYKFT group after 48 weeks was 8.78% ± 2.56% (P = 0.006) more than that in the losartan 50 mg group, which was 0.51% ± 2.54% (P = 1.000) less than that in the losartan 100 mg group. Compared with the losartan potassium 50 mg group, the SYKFT plus losartan potassium 50 mg group had a 13.39% ± 2.49% (P < 0.001) greater reduction in urine protein level. Compared with the losartan potassium 100 mg group, the SYKFT plus losartan potassium 100 mg group had a 9.77% ± 2.52% (P = 0.001) greater reduction in urine protein. With a superiority threshold of 15%, neither was statistically significant. eGFR, serum creatinine and serum albumin from the baseline did not change statistically significant. The average change in TCM syndrome score between the patients who took SYKFT (-3.00 [-6.00, -2.00]) and who did not take SYKFT (-2.00 [-5.00, 0]) was statistically significant (P = 0.003). No obvious adverse reactions were observed in any group.@*CONCLUSION@#SYKFT decreased the proteinuria and improved the TCM syndrome scores of primary glomerulonephritis patients, with no change in the rate of decrease in the eGFR. SYKFT plus losartan potassium therapy decreased proteinuria more than losartan potassium therapy alone.@*TRIAL REGISTRATION NUMBER@#NCT02063100 on ClinicalTrials.gov.

ABSTRACT

The aim of this paper was to investigate the effect of Banxia Xiexin Decoction(BXD) on inflammatory factors and intestinal flora in a dextran sulfate sodium induced ulcerative colitis(DSS-UC) mouse model, and to explore the mechanism of BXD in treating ulcerative colitis from the perspective of flora disorder. Forty C57 BL/6 J mice were randomly divided into control group, model group and BXD group. A 2.5% DSS-induced ulcerative colitis model was established. On the 8 th day, normal saline, normal saline, and BXD were given daily for 14 days. After 14 days, HE staining was used to observe histopathological changes of the colon. Serum inflammatory factor content was detected by ELISA, and the change of intestinal flora in mice feces was detected by 16 S rRNA sequencing technology. Compared with control group, the colonic tissue of mice in model group was damaged seriously, and the contents of IL-6 and TNF-α in serum were significantly increased(P<0.05). Compared with model group, mice in BXD group had less colonic damage, and the contents of IL-6, TNF-α in serum were decreased significantly(P<0.05). After creation, the richness of Patescibacteria was increased significantly at the phylum level(P<0.05). At the same time, the richness of Faecalibaculum(P<0.01), norank_f_Muribaculaceae(P<0.01) were decreased significantly at the genus level, while the richness of Turicibacter(P<0.01), Romboutsia(P<0.01), Clostridium_sensu_stricto_1(P<0.01) were increased significantly. After the intervention with BXD, the content of Patescibacteria was significantly reduced at the phylum level(P<0.05), and the contents of Lactobacillus(P<0.01), Clostri-dium_sensu_stricto_1(P<0.01), Enterorhabdus(P<0.01), Candidatus_Saccharimonas(P<0.05), Eubacterium_fissicatena_group(P<0.05) were decreased significantly at the genus level, while the contents of Dubosiella, Bacteroides and Allobaculum were increased significantly. Therefore, BXD could significantly improve the symptoms of DSS-UC mice. It not only could reduce the contents of IL-6 and TNF-α, but also could reduce the richness of Patescibacteria at the phylum level, and those of Clostridium_sensu_stricto_1, Candidatus_Saccharimonas, Eubacterium_fissicatena_group at the genus level. Inaddition, BXD could increase the richness of Bacteroides and Bifidobacterium. It suggested that BXD could play a role in the treatment of ulcerative colitis partially through reducing inflammatory factors and regulating the structure of the gut microbiota.

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 investigate the effect of ursane triterpenoids 3β,19α-dihydroxyursu-12-ene-23,28-dicarboxylic acid (Rotundioic acid, RA) on the sensitivity of adriamycin-resistant K562 cells (K562/ADM Cell) anti-tumor drug, and to explore the effect and mechanism of RA on the multidrug resistance of K562/ADM cells.@*METHODS@#CCK-8 method was used to detect the effect of RA on the sensitivity of K562 cells and K562/ADM cells to anti-tumor drug. Reverse transcription-polymerase chain reaction (RT-PCR) and Western blot were used to detect the expression level of mRNA and the protein in K562 and K562/ADM cells, and the effect of RA on the expression of MDR1 mRNA and P-gp in K562/ADM cells was also detected; Western blot was used to detect the expression of p-JNK, p-p38 and p-ERK1/2 in K562/ADM cells.@*RESULTS@#RA could increased the sensitivity of K562/ADM cells to adriamycin(the reversal factor was 1.61 times), the difference showed statistically significantly (P<0.05); the resistance factor of K562/ADM to ADM was 41.76 times. The expression of MDR1 mRNA in K562 cells was extremely low, and the protein product P-glycoprotein (P-gp) was almost not expressed; MDR1 mRNA and P-gp in K562/ADM cells were highly expressed; RA could down-regulate the expression levels of MDR1 and P-gp in K562/ADM cells. In addition, RA could upregulate the phosphorylation levels of p38 and ERK1/2 in K562/ADM cells, but it has no effect on the expression of p-JNK.@*CONCLUSION@#RA may participate in the regulation of MAPK signaling pathway by upregulating the expression levels of p-p38 and p-ERK1/2 in K562/ADM cells, and thus inhibit the transcription and translation levels of MDR1, and finally reverse the multidrug resistance of leukemia cells.

ABSTRACT

Fermentation engineering is an industrial process that uses the transformation of microorganisms or other cells to produce a specific product in a specific bioreactor. Fermentation engineering has developed from an ancient food fermentation relying solely on experience accumulation to an important production mode of food, agriculture, medicine, chemical industry and other means of production and life. It has become a key technology to support the sustainable development of human beings, and is inseparable from the continuous progress of interdisciplinary technology. The interdisciplinary integration and the continuous upward movement of China's global industrial chain will inevitably put forward higher requirements for the cultivation of fermentation engineering composite talents in the new situation. In order to constantly improve the interdisciplinary fermentation engineering compound talent training system, in recent years, the research lab has been refining and improving the concept of talent training, and actively deepening the reform of talent training system. Systematic research and practice have been carried out around the aspects of training program, enrollment system, teacher background, subject setting, scientific research practice, evaluation system, etc., which has promoted the technological progress of fermentation engineering and related supporting industries, and contributed an important force to the transformation of China from a big fermentation country to a powerful fermentation country.

After the epidemic of novel Coronavirus Disease 2019(COVID-19), construction of disease prevention and control has become a top priority. As a pioneer in the recovery of global economy and society, Shanghai should play a fundamental role in building a comprehensive system of public health and advanced disease prevention and control in the new era. In this article, we systematically categorize the requirements for the construction of disease prevention and control system in the new era, identify the weakness and challenges during and after the epidemic, and then make suggestions. It is proposed that we should utilize the important window period of the"14th Five-Year Plan", with the"Healthy China"strategy and municipal"20 Tasks for Public Health Construction"as the starting point, to make substantial contribution to the functional orientation, investment of resources, capacity building, operational mechanism and team building, which may provide scientific evidence for the reform and development of disease prevention and control system.

ABSTRACT

@#Objective    To explore the clinical issues associated with video-assisted pulmonary segmentectomy and to provide reference for better implementation of thoracoscopic pulmonary segmentectomy and reduction of perioperative complications through analyzing the clinical results of thoracoscopic segmentectomy. Methods    The clinical data of 90 patients who planned to undergo thoracoscopic segmentectomy in our department from October 2017 to December 2019 were retrospectively analyzed, including 35 males with an average age of 60.34±9.40 years and 55 females with an average age of 56.09±12.11 years. The data including lung nodule number, benign or malignant, preoperative location by Hookwire, preoperative planning and actual implementation, operation time, intraoperative blood loss, postoperative drainage volume and time of drainage tube removal, postoperative hospital stay and complications were collected and analyzed. Results    Among the 90 patients, 38 were preoperatively positioned by Hook-wire, 52 were directly operated on; 87 were completed under thoracoscopic surgery among whom 3 underwent passive lobectomy after segmentectomy under thoracoscopic surgery, and 3 were converted to thoracotomy among whom 1 underwent lobectomy. Operation time was 198.58±56.42 min, intraoperative blood loss was 129.78±67.51 mL, lymph node samples were 6.43±1.41, drainage time was 2.98±1.25 d, the amount of postoperation drainage was 480.00±262.00 mL, hospital stay was 7.60±2.38 d. In all patients, 73 had single nodules and 17 had multiple nodules. Totally 113 pulmonary nodules were resected, 14 (12.39%) were benign nodules and 99 (87.61%) were malignant nodules. There was no perioperative death or serious complications. Conclusion    For those pulmonary parenchymal nodules which meet the  indications, it is feasible to perform thoracoscopic anatomic pulmonary segmentectomy according to preoperative thin-slice CT and three-dimensional computed tomography-bronchography and angiography (3D-CTBA) reconstruction results. Preoperative Hookwire localization can ensure effective edge resection and reduce unplanned lobotomy for intersegmental nodules and non-palpable peripheral pure ground-glass nodules.
