ABSTRACT

BACKGROUND@#Norepinephrine infusion decreases hypotension after spinal anesthesia during cesarean section. This study aimed to compare the efficacy of norepinephrine infusion and ephedrine bolus against post-spinal hypotension in parturients.@*METHODS@#In this double-blinded, randomized controlled clinical trial, parturients scheduled for elective cesarean section were randomly allocated to receive norepinephrine infusion (0.05 μg·kg-1·min-1) just before spinal anesthesia continuing for 30 min or ephedrine bolus (0.15 mg/kg) just before spinal anesthesia. A rescue bolus (5 μg norepinephrine for the norepinephrine group, and 5 mg ephedrine for the ephedrine group) was administered whenever hypotension occurred. Our primary outcome was the incidence of hypotension within 30 min of spinal anesthesia administration. Secondary outcomes included maternal and neonatal outcomes 30 min after spinal block, and neonatal cerebral oxygenation 10 min after birth.@*RESULTS@#In total, 190 patients were enrolled; of these patients, 177 were included in the final analysis. Fewer patients suffered hypotension in the norepinephrine group than in the ephedrine group (29.5% vs. 44.9%, odds ratio [OR]: 0.51, 95% confidence interval [CI]: 0.28-0.95, P = 0.034). Moreover, the tachycardia frequency was lower in the norepinephrine group than in the ephedrine group (OR: 0.22, 95% CI: 0.11-0.44, P < 0.001), and patients suffered less nausea and vomiting (OR: 0.28, 95% CI: 0.11-0.70, P = 0.004). There was no difference in Apgar scores and umbilical arterial blood gas analysis between the two groups. However, neonatal cerebral regional saturations were significantly higher after birth in the norepinephrine group than in the ephedrine group (mean difference: 2.0%, 95% CI: 0.55%-3.45%, P = 0.008).@*CONCLUSION@#In patients undergoing elective cesarean section with spinal anesthesia, norepinephrine infusion compared to ephedrine bolus resulted in less hypotension and tachycardia, and exhibited potential neonatal benefits.@*TRIAL REGISTRATION@#ClinicalTrials.gov, NCT02542748; https://clinicaltrials.gov/ct2/show/record/NCT02542748.

ABSTRACT

Objective:To discuss the efficacy of addition and subtraction adjuvant therapy of Bufei decoction for pulmonary infection after tracheotomy in stroke patients (syndrome of deficiency of spleen and lung Qi) and investigate its effect on immune inflammation. Method:One hundred patients were randomly divided into control group (50 cases) and observation group (50 cases) by random number table. The patients in both groups got cefepime hydrochloride for injection, once every 12 hours, 2 g/time, at the same time, symptomatic and supportive comprehensive treatment was given. Patients in control group additionally got compound glycyrrhiza oral solution via gastric tube, 10 mL/time, 3 times/day. Patients in observation group got addition and subtraction adjuvant therapy of Bufeitang every morning and night via gastric tube, 1 dose/day. The treatment course was 14 days in both groups. At the 1st, 7th and 14th day after treatment, scores of clinical pulmonary infection scale (CPIS) and Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) were graded. The time to control pulmonary infection and the antibiotics use time were recorded. Before and after treatment, levels of T lymphocyte subsets (CD3+, CD4+,CD8+ and CD4+/CD8+), regulatory T cells of (Treg cells), immunoglobulin A (IgA), immunoglobulin G (IgG), immunoglobulin M(IgM), procalcitonin (PCT), tumor necrosis factor-α (TNF-α), interleukin-1β, IL-6 and IL-10 were detected, and safety was evaluated. Result:At the 7th and 14th day after treatment, scores of CPIS and APACHE Ⅱ in observation group were lower than those in control group (P<0.01). The time to control pulmonary infection and antibiotics use time were shorter than those in control group (P<0.01). Levels of Treg cells, CD4+ and CD4+/CD8+ were higher than those in control group (P<0.05). Levels of CD8+, PCT, TNF-α, IL-1β, IL-6 and IL-10 were lower than that in control group (P<0.01), while levels of IgA and IgM were higher than those in control group (P<0.01). There was no adverse reaction related to Bufeitang. Conclusion:Based on comprehensive treatment of western medicine for anti-infection and symptomatic support, addition and subtraction adjuvant therapy of Bufeitang can effectively control the severity of pulmonary infection caused by tracheotomy in stroke, reduce coughing and expectoration, shorten the course of pulmonary infection and the use time of antibiotics, regulate immune function and inhibit inflammatory reaction.

ABSTRACT

Objective:To verify the feasibility of a self-designed laparoscopic magnetic anchoring device for assisting thoracoscopic wedge resection.Methods:Six healthy Beagle dogs were selected as animal models, and underwent thoracoscopic wedge resection after general anesthesia. We replaced the pulmonary forceps with a magnetic anchoring device to complete the traction exposure of the lobes, and recorded the operation time of the operation, the amount of intraoperative blood loss, and the safety and feasibility of the magnetic anchoring device.Results:Six Beagle dogs successfully completed a thoracoscopic wedge resection with the aid of a magnetic anchoring device. During the operation, the magnetic anchoring device can completely replaced the exposure function of the pulmonary forceps, effectively eliminating the " chopstick effect" between the instruments during the uniportal video-assisted thoracoscopic operation. The magnetic anchoring device provided sufficient traction for the surgery to achieve a clear exposure of the field. Tissue damage and magnetic anchoring pliers slip did not occur during the operation. The operation time was(22.67±3.25)min(range 18-26 min), and the intraoperative blood loss was less than 10 ml. The experimental animals survived well after surgery.Conclusion:Magnetic anchoring device is safe and effective for thoracoscopic wedge resection, which can eliminate mutual interference between operating instruments and has potential for clinical application.

ABSTRACT

Objective:To study the feasibility of establishing gastrointestinal anastomosis by magnetic compression technique in rabbits.Methods:Ten healthy New Zealand rabbits were selected as models for gastrointestinal anastomosis by magnetic compression technique. Daughter and parent magnets suitable for gastrointestinal anastomosis in rabbits were designed and manufactured. A daughter magnet was inserted into the stomach through the purse fistula in the lack of blood vessel area of gastric body, and was pushed into the duodenum along the intestinal tract. And then a parent magnet was inserted through the stomach fistula. The daughter and parent magnets were automatically attracted and pressed the gastric and intestinal walls after they were adjusted in the proper position. The stomach fistula was closed with purse string suture. After ischemia, necrosis, detachment of the tissues between magnets, gastrointestinal anastomosis was established, and the magnets and necrotic tissues were expelled together from the body through the digestive tract. Survival of experimental animals was observed. Anastomotic specimens were obtained one month after operation. The blasting pressure of anastomotic stoma was measured, and the healing of anastomotic stoma was observed with naked eyes.Results:According to the pre-designed operative route, 10 New Zealand rabbits all successfully completed the operation and survived one month after surgery. No complications occurred during perioperative period. The operation time was 35.80±4.71 min (range 28.00-43.00 min), and the magnet discharge time was 11.40±1.56 days (range 9.00-14.00 days). Anastomotic specimens were obtained one month after the operation. Gross observation showed that the anastomotic stoma of gastrointestinal bypass anastomosis healed well, and the surrounding tissues adhered slightly. The anastomotic bursting pressure was 103.00±7.95 mmHg (range 94.00-113.00 mmHg) (1 mmHg=0.133 kPa).Conclusion:The establishment of gastrointestinal anastomosis by magnetic compression technique in rabbits is simple and effective.

ABSTRACT

Objective:To design magnets to locate colorectal neoplasms based on magnetic tracer technology, and to test its feasibility and safety by animal experiments.Methods:The magnets used for endoscopic localization of colorectal tumors consist of a tracer magnet and a pursuit magnet, both of which are ring-shaped Nd-Fe-B magnets. Eight healthy Beagle dogs were used as animal models. Tumor locations were assumed in the different parts of the colon and rectum under colonoscopy. The tracer magnet was sent to the hypothetical tumors by endoscopic soft tissue clamp and fixed near the tumors. After 24 hours, laparoscopic surgery was performed under general anesthesia. The pursuit magnet was inserted near the resected colon or rectum through the main operating hole. The tracer magnet was absorbed to the pursuit magnet to identify the location of tumors.Results:The tracer magnet and pursuit magnet were successfully designed and processed. The suction force between the tracer magnet and the pursuit magnet at zero distance was 16 N. All the 8 Beagle dogs successfully received indwelling of magnets under colonoscopy, and no magnets fell off after 24 hours. After the placement of pursuit magnet under laparoscopy, the two magnets attracted each other rapidly and accurately, and successfully completed localization of tumor site without any damage during the operation.Conclusion:Colonoscopy combined with laparoscopy for colorectal neoplasms localization based on magnetic tracer technique is simple, accurate, safe and feasible.

ABSTRACT

OBJECTIVE@#To explore the role of miR-593 in regulating the proliferation of colon cancer cells and the molecular mechanism.@*METHODS@#Bioinformatics analysis identified PLK1 as the possible target gene of miR-593. Luciferase assay was employed to verify the binding between miR-593 and PLK1, and qRT-PCR and Western blotting were used to verify that PLK1 was the direct target gene of miR-593. CCK-8 assay was performed to test the hypothesis that miR-593 inhibited the proliferation of colon cancer cells by targeting PLK1.@*RESULTS@#Luciferase assay identified the specific site of miR-593 binding with PLK1. Western blotting showed a significantly decreased expression of PLK1 in the colon cancer cells transfected with miR-593 mimics and an increased PLK1 expression in the cells transfected with the miR-593 inhibitor as compared with the control cells ( < 0.05). The results of qRT-PCR showed no significant differences in the expression levels of PLK1 among the cells with different treatments ( > 0.05). The cell proliferation assay showed opposite effects of miR-593 and PLK1 on the proliferation of colon cancer cells, and the effect of co-transfection with miR-593 mimic and a PLK1-overexpressing plasmid on the cell proliferation was between those in PLK1 over-expressing group and miR-593 mimic group.@*CONCLUSIONS@#miR-593 inhibits the proliferation of colon cancer cells by down-regulating PLK1 and plays the role as a tumor suppressor in colon cancer.

ABSTRACT

Objective@#To investigate the clinical featuresand related factors of anti-neutrophil cytoplasmic antibody associated vasculitis (AVV) with interstitial lung disease (ILD), and to explore the high-resolution computed tomography (HRCT) of the chest features between different anti-neutrophil cytoplasmic antibody (ANCA) serotypes.@*Methods@#Clinical date of 125 patients diagnosed with AAV by Tianjin Medical University General Hospital from January 1, 2010 to April 30, 2017 were analyzed retrospectively. Clinical manifestations between AAV patients with ILD or those without ILD (NILD) were compared. Patients who were complicated with ILD were divided into myeloperoxidase (MPO)-ANCA positive subset and proteimase (PR3)-ANCA positive subset, and the pulmonary computed tomographic mani-festation was compared among the two subsets. The count data was analyzed by t test, chi-square test/Fisher exact probality. Logistic regression model was applied to analyze the related factors.@*Results@#Of the 125 AAV patients, 86(68.8%) patients were complicated with inter-stitial lung disease, and the mean age of ILD subgroup was higher than that of the NILD subgroup [(66±11) years vs (56±15) years, t=-3.78, P=0.001]. Com-pared with NILD patients, ILD patients had more symptoms (χ2=4.676, P=0.031). The serum levels of carcinoe-mbryonic antigen (t=-1.908, P=0.012), carbohydrate antigen 19-9 (t=-2.286, P=0.025) and carbohydrate antigen 153 (t=-2.857, P=0.007) were higher than the NILD pa-tients. In addition, MPO-ANCA positivesubgroup was more likely to present with pulmonary fibrosis (χ2=7.736, P=0.005), reticular shadow (χ2=9.762, P=0.002) and honeycombing (χ2=4.278, P=0.039) than PR3-ANCA positive subgroup on CT images of all ILD patients. Multivariate Logistic regressive analysis showed that patients who were older than 65 years [OR(95%CI): 3.305(1.280, 8.531), P=0.013], and Birmin-gham vasculitis activity(BVAS) score higher than or equal to 15 [OR(95%CI): 3.249(1.280, 8.247), P=0.013] were risk factors for AAV patients with ILD, while the probability of PR3-ANCA positive patients complicated with ILD was low [OR(95%CI): 0.063(0.005, 0.851), P=0.037].@*Conclusion@#ILD is a very common clinical feature in AAV, especially for elders. The increase of serum CEA, CA199 and CA153 levels may be an early warning sign of interstitial lung disease. Pulmonary HRCT may more likely to present with pulmonary fibrosis in patients with MPO-ANCA positive.

ABSTRACT

Objective@#Screen the pathogenic genes of a pedigree with clinical manifestation of familial dilated cardiomyopathy in Inner Mongolia.@*Methods@#A total of 3 patients with dilated cardiomyopathy and 20 family members from the same family were examined in Ordos Central Hospital in Inner Mongolia from October, 2003 to August, 2017. Data on medical history, physical examinations, electrocardiograms, and echocardiography were obtained. 5 ml peripheral blood was sampled for per person. Chip Capture Sequencing technology was used to capture all the exons and splice sites of the genes that associated with hereditary cardiomyopathy and hereditary arrhythmia. The mutations in these genes were detected by high-throughput sequencing. All suspected pathogenic loci identified by high-throughput sequencing were verified by Sanger sequencing used for mutation detection. One hundred and fifty gender, age and race matched healthy people were included as the control group.@*Results@#Pathogenic gene variations were detected in 3 symptomatic family members and 1 carrier from the pedigree. Five pathogenic gene variations were identified in the proband (Ⅱ1), a pSer236Gly and a pArg215Cys variation in the MYBPC3 gene, a pGln90Arg variation in the DSP gene, and pAsn2912Asp and pGlu2910Val variation in the DMD gene. One pathogenic variation was detected in Ⅲ3, which was a pArg215Cys variation in the MYBPC3 gene. Two pathogenic variations were detected in Ⅲ7, a pSer236Gly variation in the MYBPC3 gene and a pGln90Arg variation in the DSP gene. Two pathogenic variations were detected in the Ⅳ7, a pSer236Gly variation in the MYBPC3 gene and a pGln90Arg variation in the DSP gene. No gene variation loci were detected in the other family members and the control group.@*Conclusion@#MYBPC3 gene, DSP gene and DMD gene variations are present in the familial dilated cardiomyopathy pedigree from Inner Mongolia, and these variations may be related with familial dilated cardiomyopathy.

ABSTRACT

Objective To explore changes in the vascular-protecting function of HDL in patients with diabetic retinopathy (DR).Methods Together 23 patients with diabetic retinopathy (DR,DR group) and 21 normal subjects (normal control group)were recruited,and the 2 mL blood were collected from each of these subjects for isolating high-density lipoprotein (HDL).And then human umbilical vein endothelial cells (HUVECs) treated with harvested HDL and PBS (blank control group) were used for detection of cell proliferation and migration in the three groups.Results Compared with the blank control group,HDL in the normal control can significantly promote the proliferation and migration of HUVECs;but when compared with the normal control group,the ability of HDL to promote cell proliferation and migration significantly decreased in the DR group,in which the proliferative capacity of the cells decreased by approximately 14.8% (P =0.027 1),and the migration ability decreased by about 49.3% (P =0.009 6).Conclusion HDL from DR patients is dysfunctional in stimulating endothelial cell migration and proliferation,which means that vascular-protecting function of HDL in patients with DR is abnormal.

ABSTRACT

<p><b>BACKGROUND</b>The crush and the culotte stenting were both reported to be effective for complex bifurcation lesion treatment. However, their comparative performance remains elusive.</p><p><b>METHODS</b>A total of 300 patients with coronary bifurcation lesions were randomly assigned to crush (n = 150) and culotte (n = 150) treatment. The primary endpoint was the occurrence of major adverse cardiac events (MACEs) at 12 months including cardiac death, myocardial infarction, stent thrombosis, and target vessel revascularization. Index lesion restenosis at 12 months was a secondary endpoint. The surface integrals of time-averaged wall shear stress at bifurcation sites were also be quantified.</p><p><b>RESULTS</b>There were no significant differences in MACE rates between the two groups at 12-month follow-up: Crush 6.7%, culotte 5.3% (P = 0.48). The rates of index lesion restenosis were 12.7% versus 6.0% (P = 0.047) in the crush and the culotte groups, respectively. At 12-month follow-up, the surface integrals of time-averaged wall shear stress at bifurcation sites in the crush group were significantly lower than the culotte group ([5.01 ± 0.95] × 10-4 Newton and [6.08 ± 1.16] × 10-4 Newton, respectively; P = 0.003).</p><p><b>CONCLUSIONS</b>Both the crush and the culotte bifurcation stenting techniques showed satisfying clinical and angiographic results at 12-month follow-up. Bifurcation lesions treated with the culotte technique tended to have lower restenosis rates and more favorable flow patterns.</p>

ABSTRACT

The BCL6 (B-Cell Lymphoma 6) gene is a proto-oncogene that is often expressed in diffuse large B-cell lymphomas (DLBCLs). BCL6 loss of function can kill DLBCL cells, demonstrating that BCL6 is necessary for the survival of DLBCL cells and could be a therapeutic target. In this study, we found that BCL6 protein levels were consistently upregulated in DLBCL tissues, whereas its mRNA levels varied randomly in tissues, suggesting that a post-transcriptional mechanism was involved in BCL6 regulation. We used bioinformatics analysis to search for miRNAs, which potentially target BCL6, and identified specific targeting sites for miR-10a in the 3'-untranslated region (3'-UTR) of BCL6. We further identified an inverse correlation between miR-10a levels and BCL6 protein levels, but not mRNA levels, in DLBCL tumor tissue samples. By overexpressing or knocking down miR-10a in DLBCL cells, we experimentally validated that miR-10a directly recognizes the 3'-UTR of the BCL6 transcript and regulated BCL6 expression. Furthermore, we demonstrated that negatively regulating BCL6 by miR-10a suppressed the proliferation and promoted apoptosis of DLBCL cells.

ABSTRACT

Gastric cancer is one of the most common malignancies worldwide; however, the molecular mechanism in tumorigenesis still needs exploration. BCL2L11 belongs to the BCL-2 family, and acts as a central regulator of the intrinsic apoptotic cascade and mediates cell apoptosis. Although miRNAs have been reported to be involved in each stage of cancer development, the role of miR-24 in GC has not been reported yet. In the present study, miR-24 was found to be up-regulated while the expression of BCL2L11 was inhibited in tumor tissues of GC. Studies from both in vitro and in vivo shown that miR-24 regulates BCL2L11 expression by directly binding with 3'UTR of mRNA, thus promoting cell growth, migration while inhibiting cell apoptosis. Therefore, miR-24 is a novel onco-miRNA that can be potential drug targets for future clinical use.

ABSTRACT

OBJECTIVE: To evaluate the current clinical application of ambroxol hydrochloride injection and promote its rational use. METHODS: Based on the Hospital Prescription Analysis Cooperation Project, 160-day prescription data about ambroxol hydrochloride injection from 2010 to 2013 was sampled randomly from the database of 82 general hospitals in six cities including Beijing, Shanghai, Guangzhou, Hangzhou, Chengdu, and Tianjin. According to the drug instruction, relevant guidelines, expert consensus, and literature, the clinical use of ambroxol hydrochloride injection was analyzed. RESULTS: Within the scope of sampling time, there were 2.67 million prescriptions of ambroxol hydrochloride injection, and 14.01 million ampoules(15 mg per ampoule) were used clinically. According to the percentage of prescription complying with the drug instruction, the six cities were ranked in descending order as follows: Hangzhou(28.03%) > Chengdu(26.25%) > Shanghai(14.66%) > Guangzhou(9.38%) > Beijing(7.72%) > Tianjin(3.98%). However, various off-label uses were found in administration route, dosage, and indications. CONCLUSION: Off-label use of ambroxol hydrochloride injection is common in clinic, which needs to be paid great attention to and to be standardized.
