Chinese Journal of Postgraduates of Medicine 2014;37(11):30-32
Objective To investigate the effect of controlled intensive blood pressure reduction on acute cerebral hemorrhage.Methods Eighty-eight patients with acute cerebral hemorrhage were divided into controlled blood pressure reduction group (controlled group,48 cases) and general blood pressure reduction group(general group,40 cases) by random number table method.Respectively given positive blood pressure reduction and according to the guidelines for treatment.The intracranial hematoma volume after admission,Glasgow coma scale (GCS) score,the United States national institutes of health stroke scale (NIHSS) score,surgery rate within 24 h after admission and fatality rate within 30 d after admission in two groups were compared.Results The initial blood loss between two groups had no significant difference(P >0.05).The intracranial hematoma volume,growth rate of intracranial hematoma,intracranial hematoma enlargement ratio in controlled group on 24 h after admission were lower than those in general group,there were significant differences [(19.3 ± 11.6) ml vs.(30.5 ± 10.9) ml,(17.8 ± 12.7)% vs.(37.1 ±25.7)%,16.7% (8/48) vs.47.5% (19/40)] (P < 0.05 or < 0.01).The GCS and NIHSS score between two groups on admission and 1,7,14 d after admission had no significant difference(P > 0.05).The surgery rate within 24 h after admission in controlled group was lower than that in general group [8.3% (4/48) vs.25.0% (10/40)],there was significant difference (P < 0.01).The fatality rate within 30 d after admission between two groups had no significant difference (P > 0.05).Conclusion Cerebral hemorrhage early control of blood pressure can not change its recent neural functional recovery and reduce the fatality rate,but may be significantly delayed hematoma enlargement and reduce the rate of surgery.
2.Targeting Strategies for Breast Cancer Stem Cells:Current Status
Journal of Sun Yat-sen University(Medical Sciences) 2017;38(5):641-650
The breast cancer stem cell theory provides a theoretical basis for explaining phenotypic and functional heterogeneity of breast cancer. These breast cancer stem cells(CSCs)promote tumor growth and are closely related to breast cancer intrinsic drug resistance. Therefore,targeted therapy of breast CSCs has become a hot area in basic and clinical research. There is growing evidence that nanoparticles can kill cancer by targeting breast CSCs ,such as targeted tumor stem cell-specific expressed surface markers(AL-DH1,CD44,and CD90),tumor stem cell stemness-related NOTCH,Hedgehog and TGF-βsignaling pathways. In this review,we summarized the characteristics and research status of breast CSCs ,and the application of nanotechnology in the treatment of breast cancer.In addition,we also summarized the research status of epigenetic drugs aimed to restrain the reprogramming of breast cancer cells.
3.The relationship between the polymorphisms of RFC and methotrexate resistance
International Journal of Pediatrics 2010;37(6):561-564
The best characterized methotrexate (MTX) transporter is the reduced folate carrier (RFC),whose gene polymorphism is one of the reasons causing MTX resistance. Based on the studies in rencent years,we have known that synthesis of mutant RFC or loss of RFC transcripts and proteins results in antifolate resistance due to incomplete inhibition of cellular enzyme targets and insufficient substrate for polyglutamate synthesis. So additional human RFC structural and mechanistic studies are absolutely essential. This paper summarizes an association between the polymorphisms of RFC and MTX resistance, which can provide a basis for clinical treatment.
4.Experimental study of animal esophageal motility using sonic wave device
Tianjin Medical Journal 2017;45(1):87-90
Objective To investigate a sonic wave device including micro-oscillator and microphone for real-time monitoring the situation of the esophageal motility of lower esophageal sphincter (LES). Methods A micro-oscillator that can actively send sound waves was located at one side of LES, and a microphone located at the other side can be to capture the sound generated from the oscillator. This device was tested in vitro by utilizing a LES simulator in quiet and noisy environment, as well as in vivo in a pilot model corresponding to moments A-D. Results In the in vitro test, the sound can be captured by the microphone, and its power strength was correlated with closing and opening of LES. The measurements showed statistically significant Pearson correlation coefficients. In the in vivo test, the LES was open and closed by an endoscope, which was monitored in real-time by another endoscope inserted into the distal stomach from the duodenum. The sound power strength corresponding to moments A-D were (-89.63 ± 0.79) dB, (-84.74 ± 0.97) dB, (-82.37 ± 1.93) dB and (-89.86 ± 0.75) dB. Conclusion The LES dynamics can be monitored by the acoustic interrogation device, which has the potential to become an effective minimally-invasive technique for studying LES dysfunction.

6. Radiofrequency ablation of cardiac fat pad at right pulmonary vein-atria junction attenuates Bezold-Jarisch reflex in canine
Academic Journal of Second Military Medical University 2010;28(12):1335-1338
Objective: To observe the influence of radiofrequency catheter ablation of the fat pad at the right pulmonary veinatria junction (RPV fat pad) on Bezold-Jarisch reflex (BJR) induced by veratridine in canine. Methods: Ten mongrel dogs were anesthetized and their chest were opened through a right thoracotomy to expose the RPV fat pad. Veratridine was injected into the left ventricle at bolus doses of 10 μg/kg through a catheter to induce BJR. The sinus cycle length (SCL), systolic arterial pressure (SAP), diastolic arterial pressure (DAP), mean arterial pressure (MAP), left ventricle systolic pressure (LVSP), left ventricle diastolic pressure (LVDP) and mean left ventricle pressure (MLVP) were measured under the baseline and after ablation of the RPV fat pad; the changes of the above parameters (ΔSCL, ΔSAP, ΔAP, ΔMAP, ΔLVSP, ΔLVDP, and ΔMLVP) were calculated. Then the same dose of veratridine was injected under the pad after ablation and the changes of the above parameters were observed. Results: BJR was successfully induced in the 8 animals; the animals has prolonged sinus cycle length (SCL) and decreased MAP and MLVP. After ablation, the prolongation of SCL after injection of veratridine was markedly reduced ([229.2±92.3] ms vs [39.3±14.1] ms,P<0.01). All the pressures were decreased after injection of veratridine, with significant decrease found only for DAP and MAP (both P<0.05). Conclusion: Ablation of the RPV fat pad can effectively attenuate the decrement of heart rate and the decrement of DAP and MAP during the BJR induced by veratridine, which provides a basis for the radiofrequency catheter ablation of vagus ganglions through endocardium.
