Apoptosis, an intrinsic cell death model which is regulated by organisms, is essential for the maintenance of tissue homeostasis in multicellular organisms. Recently, researchers on cell apoptosis have paid more attention on mitochondrion than on nucleus. Different death stimulus induces opening of PT pore, degradation of mitochondrial transmembrane potential, activation of caspase and inducing cell apoptosis. Bcl-2 and Bcl-XL inhibit cell apoptosis via mitochondrion while Bax, Bak and Bad induce apoptosis by means of regulation of mitochondrion.

Objective To discuss the artery effects of enhanced external counterpulsation for the progressive stroke patients.Methods Ninety-two progressive stroke patients who were treated in the Fourth People's Hospital of Shenzhen from August 2010 to February 2015 were selected and equally divided into the treatment group and the control group based on the random number table.The control group were received conventional therapy,and the treatment group were added treated with enhanced extemal counterpulsation therapy.Results All patients were successfully completed treatment,the C-reactive protein (CRP) and Endothelin-1 (ET-1) were presented decreased significantly after treatment (P＜ 0.05),and the C RP and ET-1 values in the treatment group were (2.09±2.11) mg/L,(13.98±6.30) mg/L,significantly lower than those of the control group((8.12±2.46) mg/L,(46.09± 11.02) mg/L;t =15.309,14.985;P＜0.05).After treatment,the FMD and NMD values in the treatment group were significantly increased from (5.26±1.34)％ to (11.93 ±2.13) ％,and from (13.20±5.33)％ to (22.98±8.34)％,in the control groupand were from (5.27±1.33)％ to (8.10±1.43) ％,and from (13.67±4.10)％ to (16.09±5.12)％ (t=16.934,21.787,8.443,12.345;P ＜0.05),and the value of FMD and NMD in treatment group were significantly higher than in the control group(t =7.982,9.113;P ＜ 0.05).The cardio ankle vascular index (CAVI) and brachial ankle pulse wave velocity (baPWV) values in the treatment group were significantly reduced after treatment,the difference was significant (P＜0.05),and compared with the control group the difference was also statistically significant (t =4.281,8.456;P＜ 0.05).Conclusion Enhanced external counterpulsation for the progressive stroke patients can effectively inhibit the expression of endothelin and inflammatory factors,improve endothelium-dependent relaxation of blood vessels,improve arterial elasticity,and thus play more effective treatment.

Objective:By comparing the volume% (V% GGOs) of ground glass opacities (GGOs) in high resolution CT (HRCT) of patients with acute paraquat (PQ) poisoning at different time points, its value in the early prognosis of patients with PQ poisoning was analyzed. Methods:The data of patients with PQ poisoning admitted to Department of Respiratory and Critical Care Medicine of Chinese Armed Police Forces from June 2017 to December 2018 were prospectively analyzed. According to the follow-up results after poisoning at 90 days, the patients were divided into the survival group and death group. Three-dimensional reconstruction technology was used to calculate the change of V% GGOs on the 3rd, 5th, and 7th day after poisoning. Chi-square test and One-Way ANOVA of variance were used to compare sex, age, and time of poisoning between the two groups. The Student's t test was used to compare V% GGOs between the two groups at different time points. The receiver operating characteristic curve (ROC) was used to determine the guiding significance of the indicator on the prognosis of patients with PQ poisoning at different time points. Results:A total of 89 patients with PQ poisoning were included in the study, 49 in the survival group and 40 in the death group. There were no statistical differences between the two groups of patients in sex, age, poisoning time, oxygenation index, mean arterial pressure, total bilirubin, blood urea nitrogen, alanine aminotransferase, and aspartate aminotransferase at admission (all P>0.05). The blood PQ concentration (mg/L) in the death group was significantly higher than that in the survival group (6.35 ±0.51 vs 3.49 ±0.21, P= 0.013). On the 3rd, 5th and 7th day after admission, the V% GGOs was significantly higher than that in the survival group (3rd day: 0.062±0.020 vs 0.049±0.007, P= 0.013; 5th day: 0.292±0.130 vs 0.123±0.044, P<0.01; 7th day: 0.334±0.116 vs 0.138±0.034, P=0.019). The area under the ROC curve showed that the prognosis AUC of the 7th day V% GGOs after poisoning was 0.967, the sensitivity was 100% and the specificity was 83.33% when the threshold was 0.16, but the time point was late. On the 5th day after poisoning, the V% GGOs judged the prognosis AUC was 0.842, the sensitivity was 82.35% and the specificity was 89.47% when the threshold was 0.14. On the 3rd day after poisoning, the V% GGOs judged the prognosis AUC was 0.708, the sensitivity was 55.00% and the specificity was 78.95% when the threshold was 0.05. At this time, the sensitivity and specificity were lower than those on the 5th and 7th day. Conclusions:The proportion of ground glass opacity volume in patients with PQ poisoning can be used to evaluate their prognosis, and the best time point is the 5th day after poisoning.

Objective To investigate the value of heart-type fatty acid-binding protein in the diagnosis of early myocardial infarc-tion.Methods In 186 cases of suspected acute myocardial infarction due to chest pain,chest tightness for 3 h,plasma CK-MB, troponin-I(CTn-I)and heart-type fatty acid-binding protein(H-FABP)were detected.The sensitivity and specificity in diagnosing early myocardial infarction were compared among 3 kinds of indexes.Results Compared with the non-infarction group and the con-trol group,plasma CK-MB,CTn-I and H-FABP in the acute myocardial infarction group were significantly increased (P <0.05 );compared with CK-MB and CTn-I,the sensitivity of H-FABP to the diagnosis of acute myocardial infarction within 3 h was higher, but its specificity was lower than that of CTn-I and higher than that of CK-MB.Conclusion For the patients with acute myocardial infarction within 3 h after onset,detecting H-FABP can increase the diagnostic rate of early myocardial infarction to a certain extent.

Objective To explore the therapeutic effect influencing factors of intra-aortic balloon pump(IABP) support during cardiac surgery perioperative period and countermeasures.Methods Clinical data of 42 patients using IABP in the cardiac surgery was analyzed retrospectively.The patients were classified into 2 groups:living group (32 patients) and died group (10 patients).The time of IABP implantation,preoperative cardiac function,the duration of cardiopulmonary bypass(CPB) and aorta block,mean arterial pressure (MAP) and inotropic score (IS) before using IABP and postoperative complications were recorded and compared.Results In died group,2 patients were used IABP preoperatively,1 patient was used intraoperatively,7 patients were used postoperatively,8 patients were in NYHA cardiac function class Ⅲ or Ⅳ preoperative,the duration of CPB and aorta block were (144.43 ± 49.03),(97.29 ± 39.99)min respectively,MAP and IS before using IABP were (57.34 ±7.25) mm Hg (1 mm Hg =0.133 kPa) and (28.22 ±17.72) scores,IABP time was (86.00 ±52.31) min.Compared with living group,all above comparisons showed significant difference [(100.43 ± 35.03) min,(60.45 ± 20.55) min,(69.34 ± 8.05)mm Hg,(10.82 ± 15.75) scores,(49.00 ± 25.23) min] (P ＜ 0.05).Postoperative complications in died group included 7 patients of ventilator dependency,6 patients of acute renal failure,5 patients of refractory metabolic acidosis,2 patients of malignant arrhythmia,1 patient of acute myocardial infarction,significantly higher than those in living group (0,4,2,0,0) (P ＜ 0.05).Conclusions Erroneously choose the timing of using IABP,poor preoperative cardiac function,prolonging CPB and aorta block time,MAP less than 60 mm Hg and high dose positive inotropic agent before using IABP,and postoperative complications are main influencing factors for clinical outcomes of IABP in cardiac surgery.Reasonably choosing adaptive indication and timing of IABP,preventing and treating postoperative complications effectively can improve effects of IABP in cardiac surgery.

OBJECTIVETo study the effect of Kaixin San on the rate-limiting enzyme in biosynthesis of melatonin (MT) and pineal body in rat depression model.

METHODThe unpredictable chronic mild stress was used to establish the rat depression model for 21 days. The rats were divided into the normal control group, the model group, Kaixin San low, medium and high dose groups (KXS 65, 130, 260 mg x kg x d(-1)) and the trazodone group. All groups were administered at 30 min after modeling each day. Rats were sacrificed and the pineal glands were isolated immediately after acquisition tail venous blood at 2:00a. m on the 22nd day. The plasma was analyzed for melatonin content by using a rat metabolic panel Milliplex kit. The pineal glands were analyzed for AANAT and HIOMT mRNA levels by Real-time quantitative PCR and for AANAT and HIOMT activity by a radiometric assay simultaneously.

RESULTThe plasma MT concentration, expression of AANT and HIOMT mRNA, activity of AANAT in rat pineal glands of the model group were significantly lower than the control group (P < 0.05), but the activity of HIOMT showed not change. Compared with the model group, all of Kaixin San groups showed increase in MT concentration in plasma (P <0. 05) , with the medium dose group revealing the highest level. Besides, the medium dose group displayed significant increase in AANAT, HIOMT mRNA level and AANAT activity (P < 0.05), but no increase in HIOMT activity.

CONCLUSIONKaixin San can regulate AANAT activity of pineal bodyand regulate MT biosynthesis in rat depression model.

Vertebral augmentation has been widely used for treating the osteoporotic vertebral compression fractures. However, the occurrence of new fractures in adjacent vertebrae is also common. In order to understand the mechanism of adjacent vertebral fractures to prevent its happening, many scholars have carried out a lot of experiments and clinical studies by different research methods for years. As a result, many theories about the mechanism of adjacent vertebral fracture have been formed. Including the patients' general conditions (age, gender, bone mineral density, body mass index, et al), material characteristics of bone cement, distribution of bone cement (volume of bone cement and under-endplate distribution, acentric or bilateral distribution, compact and solid cement filling pattern, bone cement leakage), factors of spinal sagittal imbalance, factors of anti-osteoporosis treatment and the behavioral therapy, the location of initial injured vertebral level, the degeneration of adjacent disc, all of above were considered as potential risk factors. However, various researches lead to diverse conclusions because of different methods were used and different research factors were included, some conclusions were even opposite. Therefore, it is still controversial that whether some of the risk factors were effective. In this research, the current researches and the reliability and limitations of various research methods were reviewed to put forward a relatively objective interpretation, in order to provide evidences for understanding the risks of adjacent vertebral fracture after vertebral augmentation, and to provide reference for treatment.
