Objective:To explore the effect of Brain HQ visual training on memory function in lymphoma patients with chemotherapy-related cognitive impairment.Methods:From January to December 2019, 39 hospitalized patients in lymphoma department were selected as the research object, and divided into intervention group (19 cases) and control group (20 cases) by the order of admission. The control group was given routine nursing, and the intervention group was given Brain HQ visual training. The two groups of patients used the auditory learning test to evaluate the memory function effect at the time of enrollment, after 2 cycles and 4 cycles.Results:After 2 cycles intervention, there were no statistically significant indicators for immediate recall, short-term delayed recall, long-term delayed recall, re-recognition, and correct recall ( t values were 0.575-1.248, P> 0.05); After 4 cycles of chemotherapy, the three indicators of long-term delayed recall, recognition and correct recall of the intervention group were (6.00±1.59), (9.05±1.81), (36.00±4.27) points, while (4.75±1.55), (8.05±1.73), (32.85±3.59) points of the control group, there was a statistically significant difference in ( t values were 3.384, 2.373, 3.010, P < 0.05); repeated measures analysis of variance showed The total indicators of immediate recall, short-term delayed recall, long-term delayed recall, recognition and correct recall were not statistically significant in both groups ( F values were 0.329-1.462, P>0.05). Conclusion:The effect of Brain HQ visual training on memory function are not clear, but with the change of intervention time, memory indicators are constantly improving, Brain HQ visual training has certain practicability.

The definition of esophagogastric junction (EGJ) adenocarcinoma and progress in multidisciplinary treatment for the tumor were revised in this review. Siewert classification is especially useful for the surgical approach of EGJ adenocarcinoma. Siewert I should be treated as esophageal cancer, and Ivor-Lewis esophagogastrectomy (right thoracotomy and laparotomy) is recommended as an extended two-field lymphadenectomy. For Siewert II or III tumors, left thoracophreno-laparotomy is preferred, especially in case of positive thoracic lymph nodes or positive resection margin. If there is any contraindication against thoracotomy, or a high operating risk, a transhiatal esophagectomy with lower mediastinal lymphadenectomy is an alternative. Preoperative chemoradiotherapy or perioperative chemotherapy improves overall survival and the rate of complete resection for patients with large tumor or lymph node metastasis. Neoadjuvant chemoradiotherapy is associated with high but acceptable postoperative complications. Adjuvant chemoradiotherapy remains a rational standard therapy for curatively resected EGJ cancer with T3 or greater lesion or positive nodes.

Objective:To investigate the expressions of peripheral lymph node addressin(PNAd)andGlcNAc-6-sulfotransferase(GlcNAc6ST)in endometrium and their impacts on implantation.Methods:PNAd expression in endometrium was examined by immunohistochemistry and Western Blot from 75women(12 from healthy women,in proliferative phase;63 from sterile women,of whom,27 were inearly-secretory and 36 in mid-secretory phase).GlcNAc6ST mRNA was examined by real-time PCR in41 sterile women.The 63 sterile women had underwent ⅣF-ET and were consequently divided into clini-cal pregnant(29 cases)and nonpregnant(34 cases)groups.Results:(1)PNAd localized to the mem-brane and cytoplasm of luminal and glandular epithelia.Staining was patchy and much less intense duringthe proliferative phase than during the secretory phase.In Western Blot of PNAd,four bands appeared,which were Sgp200,CD34,MAdCAM-1,GlyCAM-1 respectively,and each was positively correlatedwith the others significantly.The former three molecular levels were significantly higher during the secre-tory phase as compared with the proliferative phase.Message RNA of GlcNAe6ST was positive in all ca-ses and showed no correlation with any component of PNAd.(2)The expressions of CD34 and GlyCAM-1,but not Sgp200 and MAdCAM-1,were significantly higher in pregnant women than in nonpregnantones.However,the GlcNAc6ST mRNA level did not differ between groups.(3)No significant differ-ence was found in female age,methods of fertilization,thickness of endometrium on day hCG,cumulativeembryo score(CES)and mean score of transferred embryo(MSTE)between the groups.Conclusion:PNAd expression in the human endometrium fluctuates with the menstrual cycle.Elevated CD34 and Gly-CAM-1 during the secretory phase might be stimulative factors for embryo implantation.Defect in PNAdexpression may account for a portion of unexplained infertility.

Objective To develop a multiplex polymerase chain reaction ( mPCR) assay for detection of four pathogenic dermatophytes [Trichophyton mentagrophytes (Tm), Microsporum gypseum (Mg), Microsporum canis (Mc), and Arthroderma simii ( As) ] in laboratory animals, which could be used rapidly and simultaneously for direct detection of those four pathogens.Methods We designed 5 specific primers according to 18S-28S rRNA sequences of the four pathogenic dermatophytes reported in Genbank. The four mPCR assays were established through optimizing the concentration of primers, dNTP, TaqDNA polymerase and the annealing temperature.After verifying the specificity and sensibility, this method was used to detect 15 hair samples with artificial infection and 260 samples taken from laboratory animals.Results This mPCR technique can distinguish the four dermatophytes by producing 192 bp( Tm) ,460 bp( Mg) , 290 bp( Mc) and 602 bp( As) fragments.The sensibility for detection of the four dermatophytes was 5.9 pg/μL, 6.6 pg/μL, 9.5 pg/μL and 5.1 pg/μL, respectively.The results of 15 artificial infection samples were accurate, and the results of 260 hairs samples were negative for the four fungi.Conclusions Our results suggest that the mPCR assay developed in this study can efficiently detect the four dermatophytes, is a useful and rapid technique for rapid detection of the pathogenic dermatophytes in laboratory animals.

Objective To evaluate the effect of hydrogen-rich saline on the expression of phosphor-p38 mitogen-activated protein kinase (p-p38MAPK) during cerebral ischemia-reperfusion (I/R) in rats.Methods Seventy-two adult male Sprague-Dawley rats,weighing 220-250 g,were randomly divided into 3 groups (n =20 each) using a random number table:sham operation group (group S),I/R group and hydrogen-rich saline group (group I/RH).Cerebral ischemia was induced in chloral hydrate-anesthetized rats by 2 h middle cerebral artery occlusion in I/R and I/RH groups.The artery was only exposed but not occluded in group S.At 3 days before operation and immediately after onset of reperfusion,hydrogen-rich saline (0.6 mmol/L) 10 ml/kg was intraperitoneally injected in group I/RH,while the equal volume of normal saline was given in S and I/R groups.Neurological deficits were blindly assessed and scored at the end of 24 h reperfusion.The animals were then sacrificed,and brains were removed for microscopic examination and for determination of the cerebral infarct size (by TTC),brain water content,cell apoptosis (by TUNEL),and expression of p38MAPk and phosphor-p38MAPK (p-p38MAPK) (by immunohistochemistry and Western blot).Apoptosis index was calculated.Results Compared with group S,neurological deficit score,apoptosis index,brain water content and cerebral infarct size were significantly increased,and the expression of p38MAPK and p-p38MAPK was up-regulated in I/R and I/RH groups.Compared with group I/R,neurological deficit score,apoptosis index,brain water content and cerebral infarct size were significantly decreased,and the expression of p38MAPK and p-p38MAPK was down-regulated in group I/RH.The pathological changes of cerebral tissues were significantly attenuated in group I/RH as compared with group I/R.Conclusion Hydrogen-rich saline can reduce cell apoptosis through inhibiting p-p38MAPK expression,thus attenuating cerebral I/R injury in rats.

Objective To evaluate the effect of hydrogen on the activation of caspase-3 in brain tissues during cerebral ischemia-reperfusion (I/R) in rats.Methods Thirty-six healthy adult male Sprague-Dawley rats,weighing 220-250 g,were divided into 3 groups (n=12 each) using a random number table:sham operation (group S),I/R group and hydrogen group (group H).Cerebral ischemia was induced by occlusion of the middle cerebral artery followed by reperfusion in I/R and H groups.In group H,hydrogen-rich saline 5 ml/kg (0.6 mmol/L) was injected intraperitoneally at 3 days before establishment of the model and immediately after the onset of reperfusion.At 24 h of reperfusion,the rats were sacrificed,and hippocampal tissues were obtained for determination of neuroapoptosis (by TUNEL),apoptotic neuron count and expression of activated caspase-3 (by Western blot).The brain tissues in the ischemic area were obtained and stained with haematoxylin and eosin for examination of the pathological changes.Results Compared with group S,the expression of activated caspase-3 was significantly up-regulated,and the apoptotic neuron count was increased in I/R and H groups (P<0.05).Compared with group I/R,the expression of activated caspase-3 was significantly down-regulated,the apoptotic neuron count was decreased (P<0.05),and the pathological changes of brain tissues were significantly reduced in group H.Conclusion The mechanism by which hydrogen inhibits neuroapoptosis during cerebral I/R is probably related to inhibited activation of caspase-3 in brain tissues of rats.
