There is significant difference between grade Ⅰ and Ⅱ , Ⅲ (P＜0.05) as well as between lymph node metastasis (＋) and lymph node metastasis (-) patients (P＜0.05). Conclusion The over expression of P53, C-erbB-2 may be a useful prognostic indicator in breast cancer.

OBJECTIVETo observe the protection effect of Ligustrazine Hydrochloride (LH) on coagulation reaction and inflammation reaction in single valve replacement patients with rheumatic heart disease undergoing cardiopulmonary bypass (CPB).

METHODSTotally 40 patients undergoing single valve replacement were recruited in the study and randomly assigned to the two groups, the treatment group and the control group, 20 in each group. In treatment group LH (3 mg/kg) was intravenously infused from the jugular vein. LH (3 mg/kg) was also added in the CPB priming. In the control group LH was replaced by equal amount of normal saline. Endothelial micro-particles (EMP) count was detected before CPB, 30 min after CPB, 1 h and 24 h after CPB finished. The coagulation reaction time (R), coagulation time (K), clotting formation velocity (alpha angle), maximum amplitude (MA), coagulation index (CI), platelet (PLT), hypersensitive C reactive protein (hs-CRP), IL-6, and IL-10 were detected before CPB, 1 h and 24 h after CPB finished.

RESULTSThere was no statistical difference in aorta arresting time, period of CPB, post-operative drainage volume, plasma transfusion volume, post-operative respirator assistant time, and hospitalization time between the two groups (P >0.05). Compared with pre-CPB in the same group, the count of EMP was much higher at 30 min after CPB and 1 h after CPB finished (P < 0.01). R and K, hs-CRP, IL-6, and IL-10 increased at 1 h and 24 h after CPB finished (P <0.01,P < 0.05). The alpha angle,.MA, CI, and PLT decreased 1 h after CPB finished (P <0.01). The a angle increased, while CI and PLT decreased 24 h after CPB finished (P <0.05). Compared with the control group in the same period, the count of EMP was lower in the treatment group 30 min after CPB and 1 h after CPB finished (P <0. 05, P <0. 01). R and K values obviously decreased in treatment group 1 hour after CPB finished (P <0. 05), while a angle, MA, CI, and PLT increased (P <0. 05, P <0. 01). hs-CRP and IL-6 decreased in the treatment group 1 h and 24 h after CPB finished (P <0.05), while IL-10 increased (P <0.05). The count of PLT increased 24 h after CPB finished in the treatment group (P <0. 05).

CONCLUSIONLH had certain protection effect on the vascular endothelium undergoing CPB, and lower excessive activation of coagulation reaction and inflammation reaction in patients undergoing CPB.

Objective To study the characteristics of the transcranial electric stimulation(TES)-elicited motor evoked potentials(MEP)recorded from different points of the diaphragm,and to determine the optimal record- ing site in the diaphragm.Methods One EEG electrode was placed subcutaneously in the midline of the skull as stimulation electrode and another EEG electrode was inserted into hard palate submucously as cathode in 30 male rats.And single square wave electrical pulse was used for stimulation.The stimulation intensity was 15 mA,the du- ration of the pulse was 0.2 ms,and the stimulating interval was 200 ms.The concentric needle electrode were insert- ed into the following eight sites:the medial,intermediate,lateral crura of the diaphragm,the junction of the posterior axilla line and the inferior border of the eleventh rib,the junction of the anterior axilla line and the inferior border of the ninth rib,the junction of the intermediate line of the clavicle and the inferior border of the eighth rib,the junction of the para-sternal line and the inferior border of the seventh rib,the pars sternalis.The MEP was recorded from each point,respectively.The optimal sites of the diaphragm MEP were found and recorded.Results The MEPs were re- corded from each of the 8 sites of the diaphragm in all the rats after TES.There was no statistically significant differ- ence among the latencies of every site.But the amplitude varied from 6.08?0.46 mV in maximum along the inferior border of the ninth rib at the anterior line of the axilla to the minimum of O.91?0.03 mV at the pars sternalis. Conclusion It is safer to insert the needle along the inferior border of the ninth rib at the anterior line of the axilla, because there was certain distant from the folding part of the pleura and the amplitude of the recorded wave at this point is maximal.

Objective:To determine risk factors for postoperative esophageal refractory stenosis after endoscopic submucosal dissection (ESD) of large-scale early esophageal carcinomas and precancerous lesions.Methods:Two hundred and twelve early esophageal carcinomas or precancerous lesions in 186 patients who underwent ESD larger than 3/4 the total esophageal circumference in Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, between July 2013 and December 2017 were divided into two groups according to session number of endoscopic balloon dilatation (EBD), the refractory stenosis group ( n=69, ≥6 EBD sessions) and non-refractory stenosis group ( n=117, ≤5 EBD sessions). Student′s t-test or Mann-Whitney U test was used for univariate analysis and χ2 test and Fisher exact test were used for comparison of categorical variables. Logistic regression was used for multivariate analysis. Results:Compared with the non-refractory stenosis group, the refractory stenosis group had statistically significant differences in the longitudinal diameter of lesions, the longitudinal diameter of artificial ulcer, lesion location, the circumferential range of lesions and the composition of the muscular layer injury (all P<0.05). After eliminating the factor of the vertical diameter of artificial ulcer (because there was significant correlation between the vertical diameter of artificial ulcer and the longitudinal diameter of lesion in clinical practice), multivariate logistic regression analysis showed that the longitudinal diameter of lesion>5 cm (VS ≤5 cm: P=0.003, OR=3.531, 95% CI:1.547-8.060), the location of lesion in the upper thoracic segment (VS lower thoracic segment: P=0.001, OR=36.720, 95% CI:4.233-318.551), in the cervical segment (VS lower thoracic segment: P=0.003, OR=24.959, 95% CI:2.927-212.795), the whole circumferential lesion (VS ≥3/4 but not the whole circumference: P<0.001, OR=10.082, 95% CI:4.196-24.226) and the presence of muscular layer injury ( P<0.001, OR=7.128, 95% CI:2.748-18.486) were more likely to lead to esophageal refractory stenosis after ESD. Conclusion:The longitudinal lesion diameter of more than 5 cm, the circumferential extent of esophageal ESD, cervical or upper-thoracic esophageal lesions, and muscular layer damage are independent risk factors for postoperative esophageal refractory stenosis after ESD for large-scale esophageal cancer and precancerous lesions.

BACKGROUND: The quality of chest compressions can be significantly improved after training of rescuers according to the latest national guidelines of China. However, rescuers may be unable to maintain adequate compression or ventilation throughout a response of average emergency medical services because of increased rescuer fatigue. In the present study, we evaluated the performance of cardiopulmonary resuscitation (CPR) in training of military medical university students during a prolonged basic life support (BLS). METHODS: A 3-hour BLS training was given to 120 military medical university students. Six months after the training, 115 students performed single rescuer BLS on a manikin for 8 minutes. The qualities of chest compressions as well as ventilations were assessed. RESULTS: The average compression depth and rate were 53.7±5.3 mm and 135.1±15.7 compressions per minute respectively. The proportion of chest compressions with appropriate depth was 71.7％±28.4％. The average ventilation volume was 847.2±260.4 mL and the proportion of students with adequate ventilation was 63.5％. Compared with male students, significantly lower compression depth (46.7±4.8 vs. 54.6±4.8 mm,P<0.001) and adequate compression rate (35.5％±26.5％ vs. 76.1％±25.1％,P<0.001) were observed in female students. CONCLUSIONS: CPR was found to be related to gender, body weight, and body mass index of students in this study. The quality of chest compressions was well maintained in male students during 8 minutes of conventional CPR but declined rapidly in female students after 2 minutes according to the latest national guidelines. Physical fitness and rescuer fatigue did not affect the quality of ventilation.

Objective: To observe the efficacy of electroacupuncture (EA) plus Yi Jin Jing (Sinew-transforming Qigong Exercises) for knee osteoarthritis (KOA). Methods: A total of 60 patients with KOA were divided into an observation group and a control group according to the random number table method, with 30 cases in each group. Patients in the observation group received the treatment of EA plus Yi Jin Jing (Sinew-transforming Qigong Exercises), while patients in the control group only received EA treatment. Both groups were treated for 5 weeks. The changes of Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and visual analog scale (VAS) scores in the two groups were observed after treatment. Results: After treatment, the total effective rate in the observation group (92.3％) was significantly higher than that in the control group (70.0％), (P<0.05); the WOMAC and VAS scores in both groups were significantly lower than those before treatment, showing statistical significance (all P<0.01); there were significant differences in the post-treatment changes in the WOMAC and VAS scores between the two groups (P<0.05, P<0.01). Conclusion: EA plus Yi Jin Jing (Sinew-transforming Qigong Exercises) is clinically effective for KOA. This combined treatment can alleviate clinical symptoms.

OBJECTIVETo evaluate the therapeutic efficacy and side effects of oral Fructus bruceae oil combined with radiotherapy in the treatment of esophageal cancer.

METHODSA total of 80 patients with esophageal cancer were equally and randomly divided into two groups. The patients in Group A were treated with radiotherapy (60-65 Gy, 6-7 weeks) and oral Fructus bruceae oil (20 mL, 3 times per day for 12 weeks), while the patients in Group B were treated with radiotherapy alone. The short-term effect was evaluated by Response Evaluation Criteria in Solid Tumors (RECIST) and quality of life (QOL) was evaluated by the Karnofsky scoring (KFS). The outcome measures included complete remission (CR) rate, partial remission (PR) rate, effective rate as CR+PR, patients' QOL and adverse effects.

RESULTSAfter 12-week treatment, the CR and CR+PR were significantly higher in Group A than those in Group B (P <0.05). There was an improvement in esophageal obstruction of 87.5% and 60.0%, respectively, and in KFS of 84.6% and 43.9%, respectively, in Groups A and B.

CONCLUSIONOral medication with oral Fructus bruceae oil could effectively improve the efficacy of radiotherapy in esophageal cancer, including a reduction in esophageal obstruction, and also reduce the side effects of radiotherapy; thus it would be very promising for clinical application.

Objective To evaluate the solute clearance characteristics of REXEEDTM series dialyzers during high-flux dialysis, and explore the care characteristics. Methods A randomized crossover study of 3×3 Latin square was designed based on different dialyzers. Eighteen patients with regular hemodialysis underwent dialysis with REXEEDTM-15AC dialyzer, REXEEDTM-15UC dialyzer and controlled APS-15U dialyzer, respectively. Blood samples were obtained from the blood flow entrance and exit of dialyzers, levels of urea nitrogen, creatinine, phosphate and β2-microglobulin were detected, and solute clearance rates were calculated. Before and after the third dialysis with each dialyzer, blood samples were obtained to measure the levels of urea nitrogen and creatinine, and the rates of decrease were calculated. The vital signs of each patient were intensively observed, and the venous pressure and transmembrane pressure were monitored from the dialyzers. Results The urea nitrogen clearance rates of REXEEDTM-15AC dialyzer and REXEEDTM-15UC dialyzer were significantly higher than that of APS-15U dialyzer (P<0.05). The creatinine clearance rate of REXEEDTM-15AC dialyzer was significantly higher than that of APS-15U dialyzer(P<0.05). There was no significant difference in the rate of decrease in blood urea nitrogen among different dialyzers of the same patient(>65 % for all patients). The vital signs were stable with no adverse events during dialysis, and there was no abnormal findings in laboratory security parameters. Conclusion REXEEDTM series dialyzers are effective and safe for clinical application. Great importance should be attached to the complaints from patients during dialysis. For those with less ultrafiltration, fluid as well as uhrafiltration should be supplemented to increase the transmembrane pressure.
