OBJECTIVETo observe thee efficacy of different ways of percutaneous coronary intervention (PCI) for treating elderly coronary heart disease (CHD) patients.

METHODSTotally 470 elderly CHD patients were classified to three age brackets (equal to or more than 85 years old, 60 to 74 years old, 75 to 84 years old). They were assigned to the transradial intervention (TRI) group (236 cases) and the transfemoral intervention (TFI) group (234 cases) according to different intervention pathways. Correlated indices and postoperative clinical efficacy were compared between the two groups.

RESULTSA higher successful rate of surgery was obviously got in patients 85 years old or older than 85 than in those 60 to 74 years old and 75 to 84 years old (P <0. 05). The incidence of major cardiovascular events (MACE) was reduced at post-operative 12 and 24 months in patients 85 years old or older than 85 (P <0. 05). The case number for changing intervention pathway were increased in the TRI group with statistical difference (P <0. 05). Compared with the TFI group, the case number for changing intervention pathway was increased; the time for arteriopuncture, the time for catheterization, and the time for X-ray exposure were prolonged; the time for postoperative bedding were obviously shortened; the incidence of vascular complications at the puncture site were lowered. The incidence of postoperative 12-month MACE was lowered, all with statistical difference (all P <0. 05). The incidence of MACE within postoperative 24-month MACE decreased in patients 60 to 74 years old and 75 to 84 years old (P <0. 05). The incidence of MACE within postoperative 24 months increased in patients 85 years old or older than 85 of the TRI group with statistical difference (P <0. 05).

CONCLUSIONTRI can be preferably chosen for PC in treating elderly CHD patients.

Coptidis Rhizoma and Aconiti Kusnezoffii Radix represent hot Chinese medicine and cold Chinese medicine respectively. The purpose of this study is to observe the differentiation effect of Coptidis Rhizoma and Aconiti Kusnezoffii Radix on lewis lung cancer and compare effect of hot Chinese medicine and cold Chinese medicine on tumor progression. In this study, the rat serum containing Coptidis Rhizoma or Aconiti Kusnezoffii Radix was prepared to treat lewis lung cancer cells in vitro, and effects of the serum containing Coptidis Rhizoma or Aconiti Kusnezoffii Radix on cell differentiation, proliferation, adhesion, succinic dehydrogenase (SDH) activity and gap-junction intercellular communication (GJIC) were investigated. In vivo, the subcutaneous implant model and pulmonary metastasis model of lewis lung cancer were established. Tumor bearing mice were taken water decoction of coptis chinensis or aconite by intragastric administration bid for four weeks, and the influences of coptis chinensis and aconite on tumor progression were evaluated by body temperature, blood oxygen saturation, red cell ATPase, blood rheology, intratumor hypoxia, capillary permeability and GJIC. The results showed that the serum containing aconite could induce cell differentiation, inhibit cell proliferation and migration, promote SDH activity and GJIC in lewis lung cancer cells. The serum containing Coptidis Rhizoma increased cell adhesion and decreased SDH activity and GJIC without cell differentiation although it also suppressed cell proliferation. Aconiti Kusnezoffii Radix water decoction could keep body temperature, blood oxygen saturation, red cell ATPase and blood rheology, and improve intratumor hypoxia, capillary permeability and GJIC in tumor bearing mice, which led to slower tumor growth and less metastasis. Coptidis Rhizoma water decoction decreased body temperature, blood oxygen saturation, red cell ATPase, blood rheology and GJIC, and promoted intratumor hypoxia and capillary permeability, which resulted to more tumor metastasis although it also prevented tumor growth. These results suggested that the hot Chinese medicine could induce tumor cell differentiation and prevent tumor poison invagination, which is better for tumor treatment than cold Chinese medicine.

PurposeAlteration of the regional cerebral flow and cerebrovascular reserve (CVR) caused by cerebral artery stenosis or occlusion is an essential risk factor for ischemic stroke. This study aims to assess the CVR in patients with severe middle cerebral artery (MCA) stenosis or occlusion by using MR perfusion-weighted imaging (PWI) with CO2 inhalation stress test. Materials and MethodsPWI were performed before and after CO2 inhalation stress on 28 patients with severe middle cerebral artery stenosis or occlusion and 10 healthy volunteers. The regions of interest (ROI) were put on the affected hemisphere of the MCA blood supply area and the contralateral side in both groups. The relative cerebral blood volume (rCBV), relative mean transit time (rMTT), relative cerebral blood flow (rCBF) and CVR were measured.Results① The rCBV, rCBF and rMTT of the affected side were 149.16±33.01, 18.04±5.24, 8.65±1.81 before CO2 inhalation stress, and 156.23±21.60, 23.77±8.77, 8.72±3.01 after CO2 inhalation stress. The rCBV, rCBF and rMTT were signiifcantly increased (t=1.238, 2.561 and 2.647, P<0.05) after CO2 inhalation stress. The rCBV, rCBF and rMTT of the contralateral side were 176.22±40.12, 22.43±5.74, 8.10±3.71 before CO2 inhalation stress, and 198.54±39.87, 27.64±7.22, 8.03±2.97 after CO2 inhalation. The rCBV, rCBF was significantly increased (t=1.780 and 1.665,P<0.05) while rMTT was signiifcantly decreased (t=2.871,P<0.05) after CO2 inhalation.②The CVR of the affected side, contralateral side and control group were 18.9%, 26.8%, and 39.1%, respectively. There were significantly differences (t=1.604, 2.321 and 1.874,P<0.05) between the affected and contralateral side, the affected side and control group, the contralateral side and control group.ConclusionPWI with CO2 inhalation stress test is valuable in assessing the cerebrovascular reserve in patients with severe middle cerebral artery stenosis or occlusion.

Objective:To explore the effect of ulinastatin on prevention of acute respiratory distress syn-drome (ARDS).Methods:A prospective multicentral cohort study was conducted.The patients from three intensive care units (ICUs)of grade A tertiary hospitals in Beijing and a ICU of grade A tertiary hospitals in Cangzhou from January 2012 to December 2014,included 77 ARDS at-risk patients with uli-nastatin treatment and 108 ARDS at-risk patients without ulinastatin treatment (control)were eligible. Both groups received normal treatment;additionally,the intervention group received 600 000 units of uli-nastatin via intravenous infusion for 5 days.The control group received the same amount of saline via in-travenous infusion for 5 days.Venous blood human neutrophil elastase (HNE)and peptidase inhibitor 3 (PI3)levels were measured on days 1,3,and 7,respectively.Other outcomes included acute physiolo-gy and chronic health evaluation scoring Ⅱ (APACHE Ⅱ),body temperature,respiratory rate,heart rate,mean arterial pressure,white blood cell counts,PaO2 /FiO2 ,ARDS incident,mechanical ventila-tion time,ICU treatment and hospitalization duration,28 days mortality.Results:The PI3 levels showed no statistical difference on day 1,but significant differences on day 3 and day 7 between the two groups (P <0.01).HNE /PI3 ratio showed no statistical difference on day 1,but significant differences on day 3 and day 7 (P <0.05).PaO2 /FiO2 was significantly higher in ulinastatin group on day 3 and day 7 (P <0.05).The incident rate for ulinastatin group was 15.58%,lower than that for the control group (33.33%),and the difference was statistically significant (P <0.05).The mechanical ventilation time and ICU treatment time in ulinastatin group was shorter than that in the control group,and the difference was statistically significant (P <0.05).There were no significant effects in other factors.Conclusion:Increased dose of ulinastatin can recover the balance of HNE and its antagonist,lower the HNE’s damage to lungs,and further reduce the ARDS incident rate.

Objective To investigate the clinical significance of generalized epilepsy with febrile seizures plus(GEFS+ ). Methods The data of one family with GEFS+ were retrospectively analyzed by studying clinical manifestations, physical examinations, electroencephalogram(EEG), 24 hours dynamic EEG monitoring, et al. Some of the patients were examined by CT. Results Ⅳ 12, her chief complaints when admitted to hospital were frequent spasm for 3 days. She began to appear febrile seizures (FS) from 8 months after birth, and frequent generalized tonic - clonic FS appeared during that time. There were 36 people in 5 generations of the family including 14 patients (8 males and 6 females) ,aged from 4 years and 5 months to 82 years. FS presented in 8 cases (Ⅱ 2, Ⅲ1, Ⅲ4, Ⅲ6, Ⅳ1, Ⅳ11, Ⅳ17, Ⅴ2),febrile seizures plus(FS +) in 4 cases ( Ⅳ2, Ⅳ12, Ⅳ13, Ⅳ14), ES + and absence seizures in 1 case ( Ⅴ1 ), uncertain type in 1 case (Ⅰ2). The results of EEG indicated that 12 cases were normal and 4 cases with FS+ and 1 case with absence seizures had epileptic discharges. Apart form Ⅳ13, Ⅳ14 who were treated with magnesium valproate, the dosage for the other patients decreased, or medicine terminated or without medicine, and all the patients had no recurrence of seizures. The intelligence, movement development and neurological examinations of the family were all normal. Head CT scan of 3 cases were normal. Conclusions GEFS+ is autosomal dominant inheritance disease with conspicuous genetic heterogeneity and phenotypic heterogeneity. The apprehension of GEFS+ plays an important role in diagnosis and differential diagnosis of epilepsy in childhood.
