Objective To investigate the safety,efficacy and effects of emergent percutaneous coronary intervention (PCI) in patients from Second Affiliated Hospital,Medical College,Zhejiang University with cardiogenic shock (CS) complicating acute myocardial infarction (AMI).Method Twenty-seven patients with CS complicating with AMI were treated by PCI with intraaortic balloon counterpulsation (IABP) support.The change of hemodynamics before and after IABP and PCI,the characteristics of PCI,the mortality during hospitalization, the major adverse cardiac events (MACE) and left ventricular ejection fraction at 30-day follow-up were observed.Results The hemodynamics were significantly improved after IABP.No patients died during PCI.Two patients died after PCI and the total mortality was 7.4% in hospital.During the period of 30-day follow-up, one patient died of heart failure.The left ventricular ejection fraction greatly improved at 30 days after PCI. Conclusions The data suggested that the use of IABP during PCI in patients with CS complicating AMI was safe, decreased mortality and improved prognosis.

Objective To discuss the diagnosis and inductive chemoradiotherapy of stage Ⅲ and stage Ⅳa invasive thymoma.Methods Clinical data of 13 cases with incomplete resected invasive thymoma were analyzed retrospectively,among which 8 cases were in stage Ⅲ and 5 cases in stage Ⅳa.All the 13 cases had invasion of major vessels,pericardial and lung tissues,or had metastasis of pleura and pericardium.Each patient got pathological diagnosis by fine needle aspiration,video-assisted thoracoscopic biopsy or anterior mediastinal biopsy.After 3 cycles of NP or CAP inductive chemotherapy and synchronous radiotherapy,tumors shrank and got palliative or complete surgical resection.The Follow up ranged from 2.8 to 9 years.Results All the 13 cases were malignant thymoma,including 4 cases of type B2,6 cases of type B3 and 5 cases of type C.7 patients got radical resection and 2 got palliative resection.9 patients survived more than 3 years after operation,7 patients survived more than 5 years,one patient even lived 8 years,and the other 4 patients without getting surgery died in 4 years.Conclusion Inductive chemoradiotherapy could shrink stage Ⅲ and stage Ⅳa invasive thymoma,reduce clinical stage,improve the resection rate,and prolong survival.

Objective To study the correlation between serum bilirubin and restenosis after stent implantation of coronary heart disease (CHD).Methods Two hundred and fourtynine patients with CHD were divided into Instent-restenosis (ISR) of CHD group and non-ISR of CHD group according to their angiography findings.Theirserum bilirubin levels were compared and correlation between serum bilirubin level and ISR of CHD was studied.Results The serum bilirubin level was significantlylower in ISRof CHD group than in non-ISR group (P ＜ 0.05),in TBIL (9.9322 ± 3.8748μmol/L) to (12.08 ±4.6679μmol/L)、DBIL (3.1744 ± 1.60μmol/L) to (3.8949 ± 1.825μmol/L)、IBIL (6.757 ±2.822μmol/L) to (8.174 ± 3.388μmol/L).Conclusions The serum bilirubinlevel is lower in CHD patients with ISR than in CHD patients with non-ISR,which is an indepent risk factor for ISR of CHD.

OBJECTIVE:To observe clinical efficacy and safety of salmeterol fluticasone combined with tiotropium bromide in the treatment of COPD via different inhalation devices.METHODS:Eighty COPD patients were selected from our hospital during Jan.2014 to Jan.2015,and then divided into trial group and control group according to random number table,with 40 cases in each group.Both groups were given Salmeterol fluticasone inhalant 500 μg,bid+Tiotropium bromide inhalant 18 μg,qd.Control group was given medicine via inhalation device coming with medicine,while trial group was given medicine via gas compression type ultrasonic spray inhalator.Both groups were treated for 1 year.Blood concentration of medicine 0.5 h after medication,mMRC score and COPD acsessment test (CAT) score 3,6,9 months after treatment,the times of acute exacerbation during treatment,FEV1％ before and af ter treatment were all observed in 2 groups.The occurrence of ADR was recorded.RESULTS:Four cases withdrew from trial group and 1 case from control group.After medication,there was no statistical significance in blood concentration of fluticasone,salmeterol and tiotropium bromide between 2 groups (P＞0.05).0.5 h after medication,mMRC score of trial group was slightly lower than that of control group,without statistical significance (P＞0.05);CAT score of it was significantly lower than that of control group,with statistical significance (P＜0.05).The times of acute exacerbation in trial group during treatment was significantly less than control group,with statistical significance (P＜0.05).The decrease of FEV1％ in trial group was slightly lower than control group,without statistical significance (P＞0.05).The incidence of ADR in trial group was significantly lower than control group,with statistical significance (P＜0.05).CONCLUSIONS:For COPD patients,salmeterol fluticasone combined with tiotropium bromide via gas compression type ultrasonic spray inhalator is better than inhalation device coming with medicine in clinical efficacy and safety.

Objective To estimate the effects of camptothecin (CPT) on the expression of hypoxia-inducible factor-1α (HIF-1α) in HaCaT cells under hypoxic conditions (2％ O2),and to explore the potential therapeutic mechanism of topical CPT for psoriasis.Methods Some HaCaT cells were classified into 6 groups:5 test groups cultured in Dulbecco's modified Eagle's medium (DMEM) with the presence of CPT at 12.5,25,50,100 and 200 nmol/L respectively,and 1 control group cultured in DMEM with the presence of dimethyl sulfoxide (DMSO).All the 6 groups of cells were cultured under normoxic conditions for 12,24,48 or 72 hours or under hypoxic conditions for 12 hours.Cell counting kit-8 (CCK-8) assay was conducted to estimate the proliferation of HaCaT cells after the normoxic culture,and Western blot to quantify the protein expression of HIF-1α after the hypoxic culture.Some HaCaT cells were classified into a normoxia group (21％ O2) and a hypoxia group (2％ O2),and each group was divided into a CPT (100 nmol/L)-treated subgroup and a non-intervention subgroup (treated with the vehicle).After 12-hour culture,real-time fluorescencebased quantitative PCR was performed to measure the mRNA expression of HIF-1α.Statistical analysis was carried out by using Levene'.s test,one-way analysis of variance,Dunnett-t test and factorial analysis with the SPSS16.0 software.Results After treatment with CPT at 12.5-200 nmol/L for 12-72 hours,the proliferation of HaCaT cells was inhibited in a concentration-and time-dependent manner.More concretely,the cell proliferation rates were inhibited by 17.66％ ± 6.46％,33.11％ ± 4.63％ and 56.31％ ± 1.69％ respectively in HaCaT cells after 12-hour treatment with 200 nmol/L CPT as well as 24-hour treatment with 100 and 200 nmol/L CPT compared with the control group at the corresponding time points (all P ＜ 0.05).The protein expression level of HIF-1 α was significantly decreased in HaCaT cells after 12-hour treatment with CPT at 12.5,25,50,100 and 200 nmol/L under hypoxic conditions compared with the control group (0.348 ± 0.065,0.261 ± 0.112,0.115 ± 0.043,0.045 ± 0.024 vs.1.445 ± 0.329,all P＜ 0.05).The mRNA expression level of HIF-1α (expressed as △Ct) in the CPT-treated subgroup and non-intervention subgroup was-5.575 ± 0.29 and -5.451 ± 0.21 respectively in the normoxia group,significantly higher than that in the hypoxia group (-6.543 ± 0.57 and -6.203 ± 0.31 respectively,F =29.856,P ＜ 0.05),while there was no significant difference between the CPT-treated and non-intervention subgroups (F =1.667,P ＞ 0.05).Conclusions CPT at 100 nmol/L could inhibit the expression of HIF-1α protein,but had no obvious effect on that of HIF-1α mRNA.

microRNAs (miRNAs) are short non-protein-coding RNAs,which play important roles in the cell proliferation,differentiation,apoptosis,as well as activation of oncogenic and antioncogenic signals.Researches show that the abnormal expressions of miRNAs are closely related to the tumorigenesis,histological type,diagnosis,treatment and prognosis of lung cancer.So miRNAs may be the most potential and promising therapeutic targets for lung cancer.
