Objective To summarize the experience in treating coronary artery fistula (CAF) by using Guglielmi detachable coils. Methods During the period from July 2009 to November 2014 at the Affiliated Changhai Hospital of Second Military Medical University, interventional treatment of CAF by using Guglielmi detachable coils was performed in 40 patients. The clinical data were retrospectively analyzed. The feasibility, safety and effectiveness of this technique were evaluated. Results Successful transcatheter closure of CAF with Guglielmi detachable coils was achieved in all 40 patients; the average Guglielmi detachable coils used in each patient was(2.33±1.38) coils. No procedure-related complications occurred. Intra-operative angiography showed that residual shunt completely disappeared in 12 patients (30%) and blood flow was significantly decreased in 28 patients (70%). All the patients were followed up for 1-65 months, neither complications such as recurrent bleeding and ischemia nor stenosis and occlusion of related arteries, or fistula cavity rupture occurred. Conclusion The use of Guglielmi detachable coil in interventional treatment of CAF is safe and effective, although its long-term effect needs to be further verified.

60 Gy.The 5-year local control rates are 92%,71% and 87% respectively(P=0.9194),and 5-year overall survival rate are 68%,62% and 53% respectively(P=0.4194).There is no significant difference of overall survival and local control rate between these three dose groups.Five patients with dose of more than 50Gy died of late toxicities.Conclusions:Adjuvant radiotherapy for Stage Ⅱ and Ⅲ patients with rectal cancer dose not show dose response.There is no improvement of local control and survival due to the escalation of dose.The dose of conventional radiotherapy is better at less than 50Gy.Overdosage may lead to severe toxicities.

Two new sesquiterpenoids, named as tyromols A and B (1 and 2), were isolated from cultures of basidiomycete Tyromyces chioneus, along with two previously reported 15-hydroxy-6 α, 12-epoxy-7β, 10αH, 11βH-spiroax-4-ene (3) and agripilol C (4). Compounds 1-4 were separated and purified by silica gel, RP-18, Sephadex LH-20 column chromatography. Their structures were elucidated on the basis of extensive spectroscopic analysis including IR, MS, 1D and 2D NMR experiments.

OBJECTIVE: To determine the allelic frequency distribution and genetic parameters of nine non-CODIS DNA index systems of the short tandem repeat (STR) loci (D2S1772, D6S1043, D7S3048, D8S1132, D11S2368, D12S391, D13S325, D18S1364, and GATA198B05). METHODS: A total of 353 blood samples were collected, extracted, amplified, and analyzed from unrelated healthy individuals of Han nationality in Hunan Province, China. RESULTS: One hundred and fourteen alleles were observed in the population with corresponding allelic frequencies ranged from 0.001 0 to 0.323 0. For all the nine non-CODIS STR loci, the observed genotypic data showed no significant deviations from the Hardy-Weinberg equilibrium. The Ho, He, PIC, DP, and PE of the studied non-CODIS STR loci ranged from 0.1080 to 0.1950, 0.8050 to 0.8920, 0.7700 to 0.8600, 0.9250 to 0.9660 and 0.6070 to 0.7800, respectively. CONCLUSION Nine non-CODIS STR loci have high degrees of polymorphisms, which may be useful in individual forensic identification and parentage testing in forensic practice.

OBJECTIVETo explore the clinical effects of Dynesys system for the treatment of multiple segment lumbar degenerative disease.

METHODSA total of 28 patients with lumbar degenerative disc disease treated with Dynesys system from December 2008 to May 2011 were retrospectively reviewed. There were 16 males and 12 females, aged from 27 to 75 years old with an average of 49.1 years. Thirteen patients with multiple segmental lumbar intervertebral disc protrusion, including L3-L5 in 7 cases, L2-L4 in 1 case and L4-S1 in 5 cases. Fifteen patients with multiple segmental lumbar spinal stenosis, including L3-L5 in 10 cases, L4-L5 in 4 cases and L2-S1 in 1 case. The symptoms of lumbago and (or) intermittent claudication in all patients were treated with conservative treatments for more than 6 months and these methods did not work. Visual analogue scale (VAS) was used to analyze the lumbar and leg pain, imaging data were used to measure the intervertebral space height and intervertebral motion of fixed segment and upper adjacent segment, Oswestry Disability Index (ODI) was used to evaluate the clinical effect.

RESULTSAll operations were successful and the patients were followed up from 38 to 65 months with an average 50.6 months. At final follow-up, ODI and VAS of the low back pain and leg pain were (25.10±6.52)%, (1.25±0.70) points and (1.29±0.89) points, respectively and were decreased compared with preoperative (P<0.05). Postoperative intervertebral space heights were increased and intervertebral motions were decreased in fixed segment compared with preoperative (P<0.05). There were no significant differences in intervertebral space heights and intervertebral motions of upper adjacent segment between preoperative and postoperative (P>0.05).

CONCLUSIONDynesys system may obtain long-term clinical curative effect in treating multiple lumbar degenerative disease. It can partially preserve the intervertebral motions of the fixed segments, have little effect on adjacent segments. The long-term clinical effect of Dynesys still need longer time follow-up observation.

OBJECTIVE: To prepare gynecological Jiekang lotion and to establish its quality standard. METHODS: The Caffeotannic acid in Flos Lonicerae, the Berberine in Cortex Phellodendri and the Ammothamnine in Radix Sophorae Flavescentis were identified by TLC; HPLC was adopted to determine the content of Osthole with Hypersil DOS C18 as chromatograpic column. The mobile phase consisted of acetonitrile-water (54∶46) with a flow rate of 1.1mL? min-1. The detection wavelength was set at 321nm. RESULTS: Both the chief components in Jiekang lotion and the corresponding reference substances showed the identical discrimination reactions. The linear range of Osthole was 13～130?g?mL-1. CONCLUSION: The method is sensitive in qualitative reaction, specific in TLC identification, accurate in HPLC quantitation and recurrent. The established standard is applicable for the quality control of Jeikang lotion.

The medium and process parameters were optimized in batchaminoglycoside antibiotic JI-20A fennentation. The optimal medium consists mainly of comstarch 60g/L, peanut meal 30g/L, com slurry 8g/L, maltose 10g/L, inorganic compound and amylase moderate , methionin 1g/L and cobalt chloride 6?g/mL. It was significant to adjust medium pH after autoclaving and oxygenate the fennentation medium for the cell growth and JI-20A product.

Objective Aliginic sodium diester(ASD) liposome was prepared and its aggregation stability was evaluated.Methods ASD liposome was made by reverse phase evaporating method from egg yolk lecithin,compared with blank liposome,the size distributions and mean particle diameters of ASD liposome and blank liposome were measured respectively before and after 40 hours heating under 37℃.Results Under the condition of n(PC)∶n(CHOL) = 1∶1,the mean size diameter of ASD liposome was 4.24?m.The mean size diameter of ASD liposome changed only 0.26?m after cultivation,however,the value of blank liposome was 1.35?m.Conclusion ASD loaded in the liposome enhanced the physical stability of the liposome.
