Objective To evaluate the clinical outcomes of PCI in elder patient four years after the operation.Methods One hundred and one elder patients with ACS were divided into two groups according to the treatment during hospitalization:48 patients in the experimental group underwent primary PCI ;53 patients in control group underwent conservative treatment without PCI.For all the patients,the clinical data on admission and during the four-year follow-up were retrospectively analyzed and the incidence of cardiovascular events at different period,all-cause mortality and prognostic risk factors were compared.Results There was no statistical difference in baseline data between the two groups.The success rate of PCI in experimental group was 93.75％.Imaging examination suggested that the numbers of single vessel lesion,double- vessel lesion and three-vessel lesion were observed in 6,20 and 22 of the patients,respectively.One hundred and fifty-eight cases had lesions involved more than 70％ of the vascular diameter.The numbers of type A,B1,B2 and C vessel lesions were 12,36,48,and 62,respectively.There was no significant difference(8.33％ vs 9.43％,x2 =0.04,P =0.85 ) in the lost follow-up rates in the two groups in the four years' follow-up.The adverse cardiovascular events incidence inthe experimental group were significantly lower than that in the control group during the first 12 months after operation ( RR =2.89,x2 =3.83,P =0.05,RR95 ％ CI:1.00,8.35 ).The adverse cardiac events incidence in the experimental gr?up was significantly lower than in control group during the second 12 months after speration ( RR =3.18,x2 =6.55,P =0.01,RR95 ％ CI:1.09 - 9.29).There was no significant difference in the incidence of adverse cardiac events between the two groups during the 36 - 48 months after the operation.There was no significant difference in the survival rate between the two groups during the follow-up period ( x2 =2.22,P =0.14).The logistic regression analysis for the cardiac events and risk factors such as age,smoking,high blood pressure,Cr,CHO,TG,BS,UA,LDL-C and so on demonstrated that age ≥ 80 years,high blood Cr,BS,LDL-C and high blood pressure were risk factors for adverse cardiac events ( P ＜ 0.05 ).Conclusion The adverse cardiac events incidence was significantly lower in elder patients with ACS who underwent PCI in the following 24 months after operation,but there was no significant difference in terms of the long-term survival rate and adverse cardiac events incidence between the two groups.Age ≥80 years and high blood Cr,BS,LDL-C,high blood pressure were risk factors for adverse cardiac events.

Objective By previous overview of patients treated in our hospital, this study highlights on the intervention effects of TCM treating principle of regulating liver Qi and tonifying kidney Yin on the adverse reaction of TAM on breast cancer patients in post surgery. Methods Perspective study with the measures of randomization, and paralleling and synchronization control was conducted in the research. Results symptoms such as flush, insomnia, night sweat, palpitation, depression and heat sensation in the chest, palms and soles were improved significantly; while manifestations such as nausea, vomiting, irregular menstruation, bitter taste and dry mouth showed no significant changes. QOL changed significantly. Conclusion The application of treating principle of regulating liver Qi and tonifying kidney Yin is effective in reducing side effects caused by TAM. This result further improved the theory of TCM that the nature of liver is active, although the liver belongs to Yin in physique and but Yang in function.

Objective The prospective study was trying to explore the altering tendency of plasma concentration of E2, P and PAS after TCM intervention for post-surgery breast cancer patient who received endocrine therapy (tamoxifen).Methods By randomization, parallel, coincidence measures and the lab. technologies of AXSYM registered at Abbott lab. in the USA, plasma concentration of E2, P and FAS were tested before and after treatment. Results The results of biochemical test of plasma E2, P and FAS concentration of the two arms showed no significance difference before and after the intervention,indicating the side effects relating to TAM had nothing to do with plasma E2, P and FAS level. Conclusion It could be predicable that there must be some other by-pass ways initiating breast cancer rather than the way directly altering the level of plasma concentration of E2, P and FAS.

Objective To investigate the value of pulmonary function tests in the diagnosis and treatment of children with refractory mycoplasmapneumoniae pneumonia.Methods The clinical data of 58 children with refractory mycoplasmapneumoniae pneumonia (RMPP) from May 2015 to February 2016 were retrospectively analyzed in the Department of Paediawics, Shengjing Hospital of China Medical University.They have done bronchoscopy and interventional therapy in the acute phase.Pulmonary function test was performed 24 hours before bronchoscope examinations.The endoscopic manifestation and pulmonary function data were analysed in the study.According to whether the mucosa of endoscopic manifestation is complete, fifty-eight cases were divided into mild group and severe group, record the pulmonary function indexes of each of the children.Results Severe group decreased than mild group, both of large airway pulmonary function in children with acute severe MPP (FVC, FEV1, PEF) and small airway index (FEF25, FEF50, FEF75, FEF25-75％), and the difference was significant(P ＜ 0.05).Conclusion In the acute phase, there may be different pulmonary function,such as, expressed as a normal, performance of the restrictive or obstructive ventilation dysfunction, performance ofrnixed ventilatory dysfunction, The most common one is the change of small airway function.The more severe of the endoscopic manifestation in RMPP acute phase, the more severe the same period of pulmonary function index decreased degree.The severity of RMPP in children can be predicted by the classification and severity of pulmonary function,it can be used as an important basis for the early identification of severe MPP.Pulmonary function indicators may further guide the need for bronchoscopy intervention treatment and to evaluate the curative effect.

Objective To study the impact of beeswax removal on the content of total flavonoids separated from propolis. Methods Rutin was used as contrast calibre, and content of total flavonoids was determined by using UV spectrophotometric method. Results 8.5% of the total flavonoids lost after beeswax were removed from propolis,but the amount of total flavonoids in the process propolis and water containing was stiu much higher than that mentioned in the natural unprocessed condition. Conclusion There was little impact of beeswax removal on content of total flavonoids. Beeswax as impurity would be removed when propoli as medicine was used in complex Chinese patent medicine for treatment of cardio-cerebral vascular diseases.

AIM:To study the effects and mechanisms of a novel sulfonylureous compound 1 ｛4 [2 (4 bromobenzenesulfonaminoethyl)phenylsufonyl｝ 3 (trans 4 methylcyclohexyl) urea, G004, on antithrombosis. METHODS: The influence of compound G004 on the vasoconstrictor action, platelet aggregation and thrombosis formation was studied. The effects of compound G004 on the tail vein bleeding time in mice was examined. The influence of compound G004 on the release of prostanglandin I 2 and thromboxan A 2 from ECV304 cells was investigated. The measurement of cytosolic free Ca 2+ in attached ECV304 cells loaded with Fluo3/AM was carried out. RESULTS: Compound G004 did not inhibit the contraction of rat aorta rings induced by norepinephrine or potassium chloride, but potently inhibit human platelet aggregation challenged by arachidonic acid and adenosine diphosphate. Compound G004 significantly prolonged the tail vein bleeding time in mice and occlusion time of carotid artery in experimentally thrombotic rats. Compound G004 reduced mice mortality induced by the collagen plus epinephrine in a dose dependent manner. Compound G004 enhanced PGI 2 release and reduced TXA 2 secretion from ECV304 cells. G004 had no effect on the increase of cytosolic free Ca 2+ induced by patassium chloride. CONCLUSION: The compound G004 has a remarkable antithrombotic effect in vivo. Its active mechanism may be attributed to inhibition of platelet aggregation, enhancing PGI 2 generation and decreasing TXA 2 secretion from human umbilical vein endothelium.

Objective:To explore the risk factors of recurrence after laparoscopic myomectomy and provide references for clinical prevention and treatment.Methods:The clinical data of 216 patients who underwent laparoscopic myomectomy in Ningjin County People′s Hospital from June 2016 to December 2018 were analyzed retrospectively. The recurrence rate at 12 months after the operation was followed up, and the risk factors influencing the recurrence after laparoscopic myomectomy were screened by univariate analysis and multivariate Logistic regression model.Results:After followed up for 12 months after the operation, 24 cases had recurrence, with a recurrence rate of 11.11%(24/216). Univariate analysis showed that the recurrence after laparoscopic myomectomy was significantly correlated with surgical age, age at menarche, number of fibroids, uterine size, and gonadrotropin releasing hormone agonist (GnRH-a) treatment after the operation ( P<0.05), but was not significantly correlated with body mass index, fibroid size, fibroid type, and pregnancy after the operation ( P>0.05). Multivariate Logistic regression analysis showed that surgical age ≥ 35 years old ( OR=1.289, 95% CI 1.013-1.641), age at menarche <13 years old ( OR=1.765, 95% CI 1.167 - 2.669), and number of fibroids ≥ 2 ( OR=2.487, 95% CI 1.442 - 4.288) were independent risk factors for recurrence after laparoscopic myomectomy ( P<0.05), while GnRH-a treatment after the operation ( OR = 0.696, 95% CI 0.510-0.951) was its protective factor ( P<0.05). Receiver operating characteristic (ROC) curve analysis showed that the area under the curve of surgical age ≥ 35 years old, menarche age <13 years old, and number of fibroids ≥ 2 for predicting recurrence after laparoscopic myomectomy was 0.641 (95% CI 0.573 - 0.705), 0.719 (95% CI 0.654 - 0.778) and 0.622 (95% CI 0.554 - 0.687), and age at menarche had the greatest diagnostic efficiency. Conclusions:Surgical age ≥ 35 years old, age at menarche <13 years old, and number of fibroids ≥ 2 are independent risk factors for recurrence after laparoscopic myomectomy. Intraoperative ultrasound and postoperative GnRH-a treatment can help reduce the risk of postoperative recurrence.
