ABSTRACT

Objective:To investigate the application value of individualized full-course nutritional intervention in neoadjuvant concurrent chemoradiotherapy (nCRT) for locally advanced Siewert type Ⅱ and Ⅲ adenocarcinoma of esophagogastric junction (AEG).Methods:The perspec-tive randomized control study was conducted. The clinicopathological data of 90 patients with locally advanced Siewert type Ⅱ and Ⅲ AEG who underwent nCRT in the Fourth Hospital of Hebei Medical University from February 2012 to December 2018 were selected. Patient were divided into two groups with 1:1 according to random number table. Patients undergoing nCRT combined with individualized full-course nutritional intervention were allocated into experimental group, and patients undergoing nCRT combined with common nutritional intervention were allocated into control group. Observation indicators: (1) grouping situations of the enrolled patients; (2) changing situations of nutritional status and quality of life of patients in nCRT and preoperative waiting period; (3) efficacy evaluation and adverse effects of nCRT; (4) surgical and recovery situations. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement date with skewed distribution were represented as M ( P25, P75) or M (range), and comparison between groups was conducted using the Mann-Whitney U test. Count data were represented as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data was conducted using the non-parameter rank sum test. Repeated measurement data were analyzed using the repeated ANOVA. Results:(1) Grouping situations of the enrolled patients: a total of 90 patients were selected for eligibility. There were 77 males and 13 females, aged from 26 to 74 years, with a median age of 62 years. Of 90 patients, there were 45 cases in the experimental group and 45 cases in the control group.

ABSTRACT

Traditional Chinese medicine has a long history, unique system and perfect technology, which has been used to prevent or treat a variety of diseases in the form of compound medicine. Recently, some of the active ingredients from Chinese medicine were found to have self-assembly properties, mainly through non-covalent interactions, including π-π stacking, electrostatic interaction, hydrogen bond and coordination interactions, etc. Carrier-free nanoparticles based on self-assembly of active ingredients from Chinese medicine could not only improve the solubility of insoluble active ingredients, but also the bioavailability. As nanocarriers, the natural active ingredients could exert synergistic therapeutic effects. The strategy of self-assembly without carrier is safer and almost non-toxic compared to the commonly used nanocarriers. In addition, some ingredients from Chinese medicine could coordinate with metal ions to form stable nanoparticles, which could be applied to photothermal therapy. In this paper, we summarized and analyzed the recent achievements of carrier-free nanoparticles based on self-assembly of active ingredients from Chinese medicine, and briefly outlined the future development of this kind of nanomedicine.

ABSTRACT

OBJECTIVE@#To observe the therapeutic effect of herb-separated moxibustion combined with budesonide nasal spray (rhinocort) on moderate to severe persistent allergic rhinitis (AR) of kidney- deficiency type, and to explore the correlation between nasal temperature and condition of allergic rhinitis.@*METHODS@#A total of 70 patients with moderate to severe persistent AR were randomized into an observation group (35 cases) and a control group (35 cases, 3 cases dropped off). Both groups were treated with rhinocort, one spray on each side of the nostril (approximately 64 μg each spray), once in the morning and once in the evening, for 4 weeks. On the basis of the above treatment, the observation group was treated with herb-separated moxibustion at Shenshu (BL 23), Feishu (BL 13), Zhiyang (GV 9), Dazhui (GV 14), 3 moxibustions per acupoint, a single treatment lasting about 30 min. This treatment was given once every other day, 3 times every week, and totally continuous 4 weeks. The changes of AR symptom visual analogue scale (VAS) scores were observed before and after treatment and at 3 months follow-up after treatment. The heat variation (temperature, range) on projection areas of the nose, lungs, large intestine and kidneys of the two groups' patients before and after treatment were detected by the infrared thermal imaging diagnostic system, and the correlation between the VAS scores and nasal temperature before and after treatment was analyzed. The clinical effects of both groups were evaluated according to the VAS score.@*RESULTS@#The total effective rate in the observation group after treatment was 85.7% (30/35), which was higher than 71.9% in the control group (23/32, <0.05). After treatment and at follow-up, the VAS scores of both groups were lower than those before treatment (<0.05), and the VAS score of the observation group was lower than that of the control group at follow-up (<0.05). After treatment, the nasal temperature, pulmonary range, large intestinal range and renal range of the observation group were all lower than those before treatment (<0.05), the nasal temperature and nasal range of the control group were lower than before treatment (<0.05), and the reduction of nasal temperature, nasal range and renal range in the observation group was greater than that of the control group (<0.05). Before and after treatment, there was a correlation between VAS score and nasal temperature (<0.05).@*CONCLUSION@#The herb-separated moxibustion combining western medication has a better effect and long-term effect than western medication alone for moderate to severe persistent AR, which can improve heat variation on projected areas of the nose, lung, large intestine and kidney of patients. In addition, nasal temperature can reflect the severity of the symptoms of patients with moderate to severe persistent AR, or it can be used as a secondary indicator to evaluate condition of AR.

ABSTRACT

This paper was aimed to establish screening methods of anaphylactoid reaction caused by safflower yellow for injection based on RBL-2 H3 cell degranulation model and mice model for acute anaphylactoid reaction,and evaluate the hypersensitivity caused by safflower yellow for injection from different batches. An in vitro cell model was used to keep the cells stimulated for an hour with different batches of safflower yellow for injection as the drug group,serum-free MEM medium as negative control group and 30 mg·L-1 C48/80 as positive control group respectively. The supernatant was then absorbed,and neutral red staining technique was used to detect the effect of safflower yellow injection on the degranulation of RBL-2 H3 cells with the positive cell rate of degranulation as the indicator.An in vivo model was established to validate the experimental results,and mice model for acute anaphylactoid reaction and ELISA method were adopted to detect the plasma histamine content,and screen the hypersensitivity caused by safflower yellow for injection at the animal level by using plasma histamine content as a test index. The results of the neutral red staining experiments showed that the positive control C48/80 could cause cell degranulation,and most of the cells were deeply stained. There was significant difference in positive cell rate between different batches of safflower yellow and positive control group. In the mice model for acute anaphylactoid reaction,it was found that the positive control C48/80 significantly increased the histamine content in the plasma of mice,while the safflower yellow in each batch did not cause a significant increase in plasma histamine( P<0. 000 1). The mechanism of anaphylactoid reaction is relatively complicated. This study was mainly based on the release of histamine and other active substances by degranulation of mast cells. No significant degranulation reaction of RBL-2 H3 cells induced by safflower yellow for injection was detected,nor was the plasma histamine level significantly increased in mice from the in vitro and in vivo aspects.

ABSTRACT

Objective:To analyze the effective active ingredients of Belamcandae Rhizoma and Ephedrae Herba couplet medicines(BREH)in the treatment of bronchial asthma based on network pharmacology, in order to predict their potential targets and explore the mechanism. Method:Active ingredients and predict their targets were collected from traditional Chinese medicine system pharmacology(TCMSP) database. Drugs-components-targets network and Proteins interations network were built by STRING database and Cytoscape software. ClusterProfiler and ClueGO was used to enrich the biological function and metabolic pathway of core targets. Finally, candidate targets were mapped onto the pictures of correlative pathways. Result:The 38 effectively active ingredients were screened out, including luteolin, stigmasterol, diosmetin, naringenin, quercetin, iristectorigenin A, isorhamnetin. There were 214 candidate targets relating to bronchial asthma, and 55 core ones were selected to be mainly studied, including RAC-alpha serine/threonine-protein kinase (Akt1), tumor necrosis factor (TNF), mitogen-activated protein kinase 1 (MAPK1), vascular endothelial growth factor A (VEGFA), interleukin-10 (IL-10), NF-kappa-B inhibitor alpha (NFKBIA), and a number of relevant gene ontology(GO) functions and Kyoto Encyclopedin of Genes and Genomes(KEGG) pathways were enriched. Conclusion:BREH may regulate the Th1, Th2 and Th17 cell differentiations, Asthma, IL-17, phosphatidylinositol-3-kinases(PI3K)/Akt, MAPK, NF-κB, VEGF signaling pathways, so as to interfere the process of cell metabolism, and inhibit gene expression of proinflammatory factor in the treatment of bronchial asthma.

ABSTRACT

Objective: To explore drug resistance of human colon cancer SW480 tumor in nude mice with intravoxel incoherent motion (IVIM) imaging in vivo and its feasibility. Methods Nude mice with human colon cancer SW480 tumor in the resistant group (n=5) and non-drug resistant group (n=5) underwent IVIM imaging when the longest tumor diameter was greater than 1.50 cm, and true-diffusion coefficient (D), pseudo-diffusion coefficient (D*) and perfusion fraction (f) of the tumor were measured. Then the mice were sacrificed, and the protein expression (Western Blot) of P-glycoprotein (P-gp), multidrug resistance-associated protein 1 (MRP1), protein kinase C (PKC), necrosis (HE stain), apoptosis (TUNEL) of tumors were detected. Correlation analysis on IVIM parameters and tumor protein expression was performed. Results: The D value of non-resistance group was higher than that of drug-resistant group (P0.05). Tumor necrosis areas of the two groups were similar, the nucleus of drug-resistant group was larger than that of non-resistant group, while cells were arranged more closely and cell density was larger. There was no statistical difference in the apoptotic index between the two groups (P>0.05). Protein expression of PKC, P-gp and MRP1 in the drug-resistant group was higher than those in non-resistant group (all P<0.05). The D value was negatively correlated with the expression of P-gp, MRP1 and PKC (all P<0.05). Conclusion: The D value of tumor in nude mice model may become a significant marker to in vivo evaluate drug resistance of nude mice with human colon cancer SW480 tumor.

OBJECTIVE@#To systematically evaluate the efficacy and safety of anterior decompression and posterior decompression in the treatment of thoracolumbar fractures with spinal cord injury, so as to provide a good scientific basis for more effective treatment of thoracolumbar fractures with spinal cord injury.@*METHODS@#A clinical data about comparative study of anterior decompression and posterior decompression in the treatment of thoracolumbar fractures with spinal cord injury was searched and collected. The databases of Pubmed, Embase, Cochrane Library, CNKI, CBM, Wanfang Medical Network were searched by computer. Artificially collected journals included Spine, European Spine Journal, The Journal of Bone and Joint Surgery. Two spine surgeons independently screened the literature according to established inclusion and exclusion criteria and assessed the quality of the included studies. Meta-analysis was performed on the data using Review Manager 5.3 software, the indicators included operative time, intraoperative blood loss, postoperative tactile score, postoperative motor score, postoperative vertebral height, hospitalization time, neurological function recovery, efficiency of treatment, postoperative complications.@*RESULTS@#Fifteen randomized controlled trials (RCTs) were enrolled in a total of 1 360 patients, including 680 anterior decompression and 680 posterior decompression. The results of Meta-analysis showed that the anterior decompression group had longer operation time [MD=80.09, 95% CI(36.83, 123.34), P=0.000 3], more intraoperative blood loss [MD=225.21, 95%CI(171.07, 279.35), <0.000 01], longer hospitalization time [MD=2.31, 95% CI(0.32, 4.31), P=0.02]. And the postoperative tactile score [MD=13.39, 95% CI(9.86, 16.92), <0.000 01], postoperative motor score [MD=13.15, 95% CI(7.02, 19.29), <0.000 1], vertebral height [MD=1.36, 95% CI(0.79, 1.92), <0.000 01] in anterior decompression were higher than that in posterior decompression. There was no statistically significant differences in the efficacy of treatment [OR=1.14, 95% CI(0.56, 2.31), P=0.72], neurological recovery [OR=0.87, 95% CI(0.57, 1.33), P=0.52] between two groups.@*CONCLUSIONS@#Compared with posterior decompression, the anterior decompression has the advantages of longer operating time, more intraoperative blood loss, longer hospitalization time, higher postoperative tactile score, higher postoperative motor score, and higher injury vertebral height, But there was no significant difference in the treatment efficiency and nerve function recovery between two groups.

ABSTRACT

Objective To investigate the correlation between the expression of glucose transporters 1 (GLUT1),monocarboxylate transporter 1 (MCT1),monocarboxylate transporter 4(MCT4) and clinical characteristics in colon cancer. Methods From January 2008 to January 2016,the carcinoma tissues of 84 cases with colon cancer after gastrointestinal surgery, and 40 samples of corresponding adjacent normal colon tissues in the First People's Hospital of Hangzhou were collected. The clinical data were collected. Immunohistochemistry was performed to detect the expression of GLUT1, MCT1 and MCT4, the results were analyzed. Results The positive expression rates of MCT1,GLUT1 and MCT4 in colon cancer were 54. 8% (46/84),47. 6% (40/84),58. 3% (49/84),respectively, which were significantly higher than those of the control group[12. 5% (5/40),7. 5% (3/40),15. 0% (6/40)],the differences were statistically significant (χ2=19. 987,19. 253,20. 615,all P<0. 01). The expressions of GLUT1, MCT1,and MCT4 were not related to gender,age and tumor size,but related to lesion location,differentiation,lymph node metastasis,distant metastasis and clinical stage( GLUT1:χ2=6. 227,11. 629,10. 029,14. 817,4. 709;MCT1:χ2=6. 891,8. 615,9. 185,5. 337,16. 131;MCT4:χ2=8. 641,7. 077,12. 131,6. 917,7. 077;all P <0. 05). Conclusion High expression of GLUT1,MCT1 and MCT4 were observed in colon cancer. GLUT1,MCT1 and MCT4 may affect the development of colon cancer through energy metabolism pathway in colon cancer tissues.

ABSTRACT

<p><b>OBJECTIVE</b>Combining K-line (the connecting line of the midpoint of C₂ and C₇ spinal canal on the cervical lateral X-ray film) to analyze the relationship between cervical range of motion of patients with ossification of posterior longitudinal ligament (OPLL) and surgical prognosis.</p><p><b>METHODS</b>A total 42 patients with ossification of cervical posterior longitudinal ligament underwent cervical posterior single open-door laminoplasty between April 2014 and March 2017 were retrospectively ananyzed. The patients were dividing into K-line (+) group and K-line (-) group according to the position realationship of OPLL and K-line. The lesion of ossification of the posterior longitudinal ligament was not over than the K-line known as K-line (+). Conversely, the lesion of ossification of the posterior longitudinal ligament crossing the K-line was called K-line (-). Preoperative and postoperative 3 months JOA scores were observed, and postoperative 3 months JOA improvement rate were computed to assess patient's neurological function recovery. Preoperation and postoperative 3 months, OPLL occupation ratio (OOR), cervical lordotic angles (CLA) and cervical lordotic value (CLV) were measured respectively. The realationship between postoperative neurologic functional recovery in patients of CLV>0 group and CLV<=0 group was evaluated in different K-line subgroups.</p><p><b>RESULTS</b>For the patients in K (+) group and K (-) group, preoperative CLA were (14.7±9.6)° and (-6.4±9.5)°(<0.05) respectively, postoperative at 3 months CLA were (14.0±8.0)° and (-1.4±10.4)°(<0.05) respectively; preoperative JOA scores were 10.9±3.2 and 11.2±2.5 (>0.05) respectively, postoperative at 3 months JOA scores were 14.2±1.8 and 12.6±2.2 (<0.05) respectively, and postoperative at 3 months JOA score improvement rate were (54.7±17.6)% and (25.5±15.7)%(<0.05) respectively. In the K-line (+) group, there were 29 patients in CLV>0 group at 3 months after operation, with improvement rate of (52.3±17.2)%, and 4 patients in CLV<=0 group, with improvement rate of (72.2±7.8)%. The improvement rate of the patients in CLV<=0 group was significantly better than that of the patients in CLV>0 group (<0.05).</p><p><b>CONCLUSIONS</b>No matter whether the ossification of cervical posterior longitudinal ligament was classified as K-line (+) or K-line (-), the cervical posterior single open-door laminoplasty can improve the neurological symptoms of patients, especially the patients in the K-line(+) group with better prognosis. The patinets in K-line(+) group, when postoperative at 3 months CLV>0, their improvement rate was lower than that of the patients with postoperative at 3 months CLV<=0.</p>
