Objective To observe the effect of different doses of atorvastatin in treating elderly acute coronary syndrome.Methods Totally 78 cases with acute coronary syndrome were randomly divided into two groups:low-dose atorvastatin group and high dose atorvastatin group,39 cases for each.The triacylglycerol (TG),total cholesterol(TC),low-density lipoprotein-cholestrol (LDL-C)and high-density lipoprotein-cholestrol (HDL-C) were compared between before and after the treatment.The adverse drug reactions were observed.Results Before treatment,the levels of TG,TC,LDL-C and HDL-C were not statistic significant between the two groups.After treatment of 1 month,3 months,6 months and 12 months,TC and LDL-C of the two groups were decreased than those before treatment,and TC and LDL-C of high-dose atorvastatin group were lower than those of low-dose atorvastatin group,but HDL-C level was not changed compared with before treatment.After treatment of 3 months,6 months and 12 months,TG levels of the two groups were decreased than those before treatment,and TG of high-dose atorvastatin group were reduced than those of low-dose atorvastatin group.The incidence rate of cardiovascular events of high-dose atorvastatin group was significantly lower than those of low-dose atorvastatin group.There was no difference in the incidence rate of adverse drug reactions between the two groups.Conclusions I(s worthy to apply high-dose atorvastatin in clinical treatment for acute coronary syndrome because of its ability to decrease the levels of TG,TC,LDL C,HDL-C and cardiovascular events.

Objective To investigate the safety of treatment of symptomatic middle cerebral artery stenosis with Gateway-Wingspan system by reviewing the data on complications.Methods Forty-seven patients with symptomatic middle cerebral artery stenosis treated with Wingspan system were respectively analyzed and emphasis was paid to cases with complications.Relevant data was collected such as characteristics of patients and lesions,selection of ballon and stent and radiographic information.Results Complications were found in 4 patients (8.5％),which were due to cerebral vasospasm,heperperfution syndrome,artery branch rupture and subacute stent thrombosis respectively.Two patients experienced symptomatic intracranial hemorrhage (4.3％)and one of them died (2.1％).The morbidity of severe complications was 6.4％.The success rate of stent implantation was 100％.Mean artery stenosis reduced from (83.5 ± 10.0)％ to (19.8 ± 9.2)％ after Wingspan stent implantation.Conclusion Middle cerebral artery stenting angioplsty greatly improved the stenosis with high technical success rate.However,the rates of cerebral vascular complications and symptomatic intracranial hemorrhage were relatively high in this study,which needs to be widely verified in practice.

3.0 cm in diameters.Contrast-enhancement CT showed tumors with abundant blood vessel,1 case appeared as uniform enhancement and was difficult to distinguish between tumor body and internal carotid and external carotid because of the iso-density of them.On MRI,the flow void blood vessels inside the tumors could be identified and internal carotid and external carotid separated.MRA displayed all the relation between the tumors and carotid and its branches.DSA could demonstrate the supply arteries of the tumors.Conclusion Ultrasonics,CT,MRI and DSA have own definitely characteristic value in diagnosing carotid body tumor.

Objective To investigate the differences in sex hormone levels between hypospadias and circumcision groups.Methods Fifty cases of circumcision and 137 cases of hypospadias the dihydmtestosterone (DHT) value was tested with radioimmunoassay,and testosterone was tested with lightimmunoassay.Results DHT value was (64.51 ±32.10)pg/ml in circumcision group,and (46.72 ±28.94)pg/ml in hypospadias group (P ＜0.05).DHT value in hypospadias type Ⅰ,Ⅱ,Ⅲ,and Ⅳ were (50.20 ±32.90)pg/ml,(46.63 ±25.67)pg/rnl,(51.60 ±32.16)pg/ral,and (39.02 ±26.32)pg/ml,respectively (P =0.29).The differences between circumcision and hypospadias groups were statistically significant (P =0.00).Luteinizing hormone (LH) and testosterone (T) in children with hypospadias were significantly lower than those in children in the circumcision group (P ＜ 0.05).No statistically significant difference was found between two groups in follicle-stimulating hormone (FSH),estradiol (F2),and prolactin (PRL) (P ＞ 0.05).No statistically significant differences were found in FSH among all types of hypospadias (P ＞ 0.05).Conclusions Inadequate secretion of T or activity insufficiency and functional deficiency of 5 alpha reductase (SRD5A) are likely found in children with hypospadia.Inadequate secretion and low T value might be found in LH-T shaft in children with hypospadia.The normal T value in some children with hypospadia does not show that androgens produced during pregnancy are normal.

Jasgranoside B (1) is a new compound. Compounds 2-6 were isolated from Jasminum officinale L. var. grandiflorum for the first time.

OBJECTIVE: Lymphoepithelial carcinoma (LEC) of salivary glands is a rare malignant neoplasm. The purpose of this research was to investigate the clinicalpathologic features and treatment methods of this rare disease. METHOD: The clinical data and treatment outcomes of 17 patients from 2006 to 2012 were reviewed retrospectively. RESULT: Ten males and seven females with a ratio of 1. 43:1 were involved. The II, III, IV stage cases were 7 (41.2%), 4 (23.5%), 6 (35.3%), respectively. The average follow-up duration was 2.56 years, and 12 patients had no evidence of recurrence. Five patients had local recurrence and (or) distant metastases within three years after surgery, including 4 deaths. CONCLUSION LEC in salivary gland is a high grade malignant tumor in oral and maxillofacial region, occurring predominately in parotid gland and submandibular gland. To prevent distant metastasis, radical surgery combined with chemoradiotherapy should be adopted.

BACKGROUND:The therapeutic regimen of intraarticular calcaneal comminuted fractures commonly selects plate and screw fixation. However, for case of posterosuperior calcaneal fracture, the weakness of achil es tendon stretch and plate screw fixation results in difficulty or maintenance of reduction. OBJECTIVE:To investigate the therapeutic effects of open reduction and internal fixation with steel screw and Steinmann pins for comminuted calcaneal intra-articular and posterosuperior fractures. METHODS:From December 2009 to December 2013, forty patients with fractures of comminuted calcaneal posterosuperior fractures were randomly divided into two groups. In the control group, patients were treated by open reduction and internal fixation by plate screw only. In the experimental group, patients were treated by open reduction and internal fixation by combination of plate screw and Steinmann pin. The Gissane and Bohler angles of the calcaneus were measured from lateral radiograph before and 4 weeks after surgery, and the MARYLAND score was assessed at the last fol ow-up. Gissane and Bohler angle and MARYLAND score were compared in each group and among different groups. RESULTS AND CONCLUSION:Al patients were fol owed up for 9-23 months. BOHLER and GISSANE angles were significantly bigger at 4 weeks after surgery compared with pre-treatment in both groups (P<0.05). BOHLER and GISSANE angles were significantly bigger in the experimental group than in the control group at 4 weeks after surgery (P<0.05). During final fol ow-up, the average score by MARYLAND Foot Score was 78 in the experimental group and 67 in control group, with their excellent and good rate of 80%and 73%. The excellent and good rate was significantly higher in the experimental group than in the control group (P<0.05). These data indicated that open reduction and internal fixation with combination of plate screw and Steinmann pin has better efficacy in treatment of the comminuted calcaneal intra-articular and posterosuperior fractures compared with plate and screw fixation alone. Their fixation is firm. Functional exercise can be performed earlier. Postoperative recovery of function of the affected limbs is better than plate and screw fixation alone.
