Objective:To analyze the feature of anaphylactic shock induced by alprostadil injection. Methods: Totally 1624 pa-tients treated with alprostadil injection in our hospital from January to March 2014 were undergone adverse drug reaction monitoring. Six cases of anaphylactic shock induced by alprostadil injection were statistically analyzed. Results:6 cases of anaphylactic shock induced by alprostadil injection occurred in the department of intervention and most of thd reaction happened in arterial injection. Two lot num-ber of drugs were in high frequency. Patients showed a sharp fall in blood pressure, chest discomfor, palpitation, shortness of breath, paleness, sweating and other symptoms. After anti allergy, blood pressure, oxygen the rapy and other treatment measures vital signs gradully stabilized. Conclusion:Anaphylactic shock induced by alprostadil injection is in correlation with the administration mode of artery injection. The change of the patient' s condition and vital signs should be closely observed when we inject the patient with alpros-tadil injection. We must prevent the occurrence of serious adverse reactions.

BACKGROUND:Shengji Yuhong col agen showed good curative effect of promoting angiogenesis and tissue healing compared with Shengji Yuhong Gao and col agen alone or gelatin alone.
OBJECTIVE:To explore the curative effect and mechanism of subcutaneous implantation of Shengji Yuhong col agen in rabbits in promoting angiogenesis and repair.
METHODS:Shengji Yuhong col agen as the experimental group and collagen as the control group was implanted inside the rabbit subcutaneous pockets of the back of New Zealand rabbits. The implanted samples and
surrounding tissues were obtained at 3, 7, 14, 28 and 56 days fol owing surgery. Pathological sections were made and the repair of surrounding tissue was observed. Hemoglobin levels in col agen were measured.
Immunofluorescence and CD34 dyeing marking method were utilized to observe capil ary angiogenesis. Western blot assay was employed to examine vascular endothelial growth factor and angiogenin-1 expression.
Immunohistochemistry was used to observe the secretion of typeⅠ and Ⅲ col agen on the surrounding tissues.
RESULTS AND CONCLUSION:The experimental group showed increased subcutaneous vascularization. There were reduced inflammatory exudation, granulation tissue hyperplasia, and mature fiber connective tissue at 28 days.
Angiogenesis and hemoglobin contents were greater in the experimental group than in the control group (P<0.05 or P<0.01). At 3 and 7 days fol owing surgery, vascular endothelial growth factor and angiogenin-1 expression was greater in the experimental group than that in the control group (P<0.05 or P<0.01). The secretion of type Ⅰ col agen was
identical between the experimental and control groups. However, the secretion of type Ⅲ col agen was higher in the experimental group than in the control group at 28 and 56 days (P<0.05), and the proportion of type Ⅰ and Ⅲ
col agen was lower in the experimental group than in the control group at 28 and 56 days (P<0.01). These suggested that Shengji Yuhong col agen can significantly promote angiogenesis in the surrounding tissues with the possible
mechanisms of adjusting the protein expression of vascular endothelial growth factor and angiogenin-1. At the same time, it has the function of regulating col agen formation with better ratio of typeⅠ and type Ⅲ col agen to acquire higher
quality of wound healing with reduced scar formation.

Objective To examine the expression levels of cyclin Dl in the patients with chronic myelogenous leukemia (CML), and evaluate the pathogenesis and clinical significance of cyclin Dl in CML Methods The real-time quantitative polymerase chain reaction (RQ-PCR) was performed to detect the expression levels of cyclin Dl in the bone marrow samples of 18 patients with CML, and 16 samples of benign hemopoietic patients. The relationship between the expression levels of cyclin Dl and the progression and prognosis of patients with CML were analyzed. Results The level of cyclin Dl was higher expressed in 18 patients with CML than the control group (P <0.001). The levels of cyclin Dl was apparently higher expressed in accelerated phase /blast crisis phase than in chronic phase (P <0.05). And the RQ-PCR method showed the tendency that a significant increase was observed in the levels of cyclin Dl from 0.1980 in control group to 1.4002 in chronic phase and 5.4540 in accelerated phase /blast crisis phase. Conclusion The cyclin Dl overexpressed in CML, the roles of cyclin Dl in CML might be an oncogene expressed. The expression level is correlated with the progression and prognosis of patients with CML.

Objective To investigate the dynamic change and its clinical significance of serum thymidine kinase 1 (STK1) in patients with non-small-cell lung cancer (NSCLC) when undergoing 4 cycles of chemotherapy. Methods We detected STK1 levels of 59 patients with NSCLC throughout 4 cycles of chemotherapy using Enhanced Chemiluminescence Western Blot and analyze its relationship with chemotherapy responses . Results STK1 levels with different chemotherapy regimens had no significant difference. STKK1 levels in patients with effective response were significantly lower after 4 cycles of chemotherapy. STK1 levels in patients with effective response were significantly lower than those in non-responders throughout 4 cycles of chemotherapy. The positive rates of STK1 in those with effective response were lower than those in non-responders after the last two cycles of chemotherapy. STK1 levels between lung squamous carcinoma and lung adenocarcinoma had no significant difference. Conclusion The detection of the changes of serum TK1 in patients with NSCLC undergoing chemotherapy is useful in evaluating the effect of chemotherapy and the later therapeutic schedule.

Objective To explore the expression plasma heat shock protein HSP90αand its clinical signifi-cance for lung cancer patients . Methods Plasma levels of HSP90α protein of 60 patients with lung cancer and 24 healthy individuals are detected by ELISA analysis . Results The average plasma levels of HSP90αprotein [(190.338 ± 105.861) ng/mL] in patients with lung cancer were significantly higher than in healthy con-trols [(41.020 ± 19.736) ng/mL, t = 10.480, P < 0.001]. The sensitivity of HSP90α is higher than CEA, NSE, CYFRA21-1. The sensitivity of HSP90α, CEA, NSE, CYFRA21-1 and STK1 is 100%. HSP90α is correlated with STK1 and metastasis (χ2 = 4.656, P = 0.031). Conclusions This study demonstrates that the plasma level of HSP90αprotein is a useful diagnostic biomarker in lung cancer. The sensitivity is much higher when HSP90αcom-bined with CEA, NSE, CYFRA21-1 and STK1.

Objective To investigate the relations and evaluation value of serum thymidine kinase 1 (sTK1) in the treatment of patients withacute exacerbation of chronic obstructive pulmonarydisease (AECOPD). Methods The retrospective treating studies were performed on 104 patients with AECOPD , sTK1 level was de-tected by chemiluminescence dot-blot assay before and after treatment , and the correlation between the expression of sTK1 and CRP after treatment in the two groups was analyzed. Results The levels of sTK1 and CRP in the ef-fective group significantly lowered after treatment (P < 0.05). The expression of sTK1 in the effective group and in the ineffective group after treatment was significantlycorrelated with CRP (P < 0.05). Conclusion sTK1 can be used as a valuable indicator to evaluate the severity of AECOPD and to estimate the efficacy of AECOPD thera-py.

Objective To examine the influence of gender difference on the reperfusion delay in patients with ST-elevation myocardial infarction (STEMI).Methods A total of consecutive 325 patients with STEMI were analyzed admitted in the 306 Hospital of PLA from Jan.2011 to Dec.2015.Patients were divided into two groups:male group (n=268) and female group (n=57).The clinical data and the time intervals including symptom onset to first medical contact (So-to-FMC),transfer delay (FMC-to-D),FMC to balloon dilatation (FMC-to-B),activation delay and door to balloon (D-to-B) time were compared between different gender groups,and the prognosis was observed.Results The overall median of pre-hospital delay was 125 minutes.The median of prehospital delay time (male 119.5min vs.female 160.0min) and So-to-FMC time (male 69.5min vs.female 100.0min) were longer in female than in male patients,but no statistical difference existed (P＞0.05) between the two groups in pre-hospital delay,So-to-FMC,FMC-to-B,D-to-B and total ischemia time.Compared with male patients,female patients were more likely to have additional comorbidities,such as hypertension and diabetes mellitus,and lower rate of smoking (P＜0.05).However,the incidence of major adverse cardiac and cerebrovascular events (MACCE) showed no significant difference between female and male patients at 30-day (male 5.22％ vs.female 5.26％) and I-year (male 10.82％ vs.female 8.77％) follow-up (P＞0.05).Conclusion The influence of gender on reperfusion delay is gradually weakening.

A 10-day-old male infant presented with skin erythema and blisters for 6 days. Skin examination showed scattered or confluent erythema all over the body, tense blisters of varying sizes on the normal skin or an erythematous base, and some blisters were ulcerated and erosive; bloody bullae and erythematous erosive patches could be seen on the oral mucosa. Histopathological examination revealed subepidermal blisters, and there were some neutrophils and a few eosinophils in the blisters. Direct immunofluorescence assay showed homogeneous linear IgA and granular C3 deposits along the basement membrane zone, without IgG deposits. The diagnosis of neonatal linear IgA bullous dermatosis was confirmed. After comprehensive treatments including nutritional support and anti-infection treatment, skin erythema and blisters subsided, and the mucosal damage was attenuated. The telephone follow-up 16 months after discharge showed that the infant was in good general condition with normal growth and development, and the oral mucosal lesions had subsided and healed, without new skin lesions.

Objective: To explore the effects of miR-124-ROCK1 signal pathway in the damages of glomerular endothelial cells (GEnCs) induced by high glucose. Methods: Rat glomerular endothelial cells were cultured in different glucose concentrations: normal control group (NG: 5.5 mmol/L), high glucose group (HG: 30.0 mmol/L), and cells were treated with ROCK1 inhibitor Y27632, miR-124-3p mimic, miR-124-3p inhibitor. The expressions of ROCK1 activity, cell apotosis and tight junction proteins were detected by Western blot. The cell tight junction protein ZO-1 in those groups were assessed by laser scanning confocal microscope. Results: High glucose significantly decreased miR-124 expression (P<0.01), ROCK1 activity (P-MYPT1/MYPT1), and cell apoptosis (Cleaved-Caspase3/pro-Caspase3) were found increased while the tight junction proteins ZO-1and Occludin were found decreased in these cells (P<0.05 all P<0.01), However, when pretreated cells with ROCK1 inhibitor Y27632, these injuries were significantly reversed. In cells transfected with miR-124-3p mimic, p-MYPT1/MYPT1 was decreased. p-MYPT1/MYPT1 was however increased in cells transfected with miR-124-3p inhibitor (P<0.05), indicating that miR-124 could directly inhibit ROCK1 activity. The increased ROCK1 activity and apoptosis, as well as the decreased tight junction proteins induced by high glucose were significantly suppressed as miR-124-3p mimic transfected in GEnCs. Conclusions According to our experiments, high glucose suppressed miR-124 in glomerular endothelial cells, consequenctly activating ROCK1 activity to damage endothelial cells. MiR-124 overexpression could ameliorate these damages induced by high glucose, suggesting that miR-124 might be a new therapeutic target to prevent glomerular endothelial cells injuries in diabetic nephropathy.
