Patent ductus arteriosus (PDA) is a frequent congenital heart disease .Incidence rate of PDA accounts for 10% ~21% of total incidence rate of congenital heart disease .In recent years ,along with the continuous deepening understanding of anatomical structure and pathology of PDA ,there were a variety of treatment methods ,including drug therapy ,interventional therapy and operation .The present article made a review about indications ,contraindi‐cations ,advantages and disadvantages of above three treatments .

Objective To discuss pathogenesis of low back pain induced by chronic compartment syndrome. Method Thirty patients who had definite chronic lumboscaral compartment syndrome without other lumbal diseases were choosed respectively to test muscle force of lumbar and abdomen,intra-sacrospinal muscle pressure,blood routine,ESR,CK,CK-MM,LDH and LDHs.All patients received decompressive operation.Skeletal muscle specimens taken from sacrospinal muscle in each operation were possessed for histological and ultrastructuml observation. Result All of enzyme tests were normal.The author could observe the dissolved degeneration of part of sacrospinal muscle fibers,muscle fiber hypertrophy,and a small quantity of inflammatory cell infiltration with a light microscope.Focal solution of muscle fiber,the aggregation of mitochondria around the nucleus,the increase of lipid droplet and lysosome in cyte,and the proliferation and differentiation of muscle satellite cell could be observed with an electron microscope. Conclusion Pathogenesis of chronic lumboscaral compartment syndrome may be as followed.Intra-compartmental pressures increase,causing metabolism disturbance of the tissues under fascia compartment,damaging skeletal muscle chronically,then inflammatory factors are released,which stimulates posterior branch of spinal nerves,and finally induces low back pain.

Objective: To study the pharmacodynamic differences between Simiao Pills with crude Atractylodis Rhizoma and bran stir-baked Atractylodis Rhizoma on the treatment of adjuvant arthritis. Methods: Wistar rats were randomly divided into blank control group (normal saline), model control group (normal saline), Tripterygium wilfordii glycosides (TWG) group (9.45 mg/kg), low-and high-dose (1.080 and 4.320 g/kg) Simiao Pills (crude Atractylodis Rhizoma) group, low-and high-dose (1.080 and 4.320 g/kg) Simiao Pills (stir-baked Atractylodis Rhizoma with bran) group. Except the blank control group, the other groups were modeled to adjuvant arthritis with complete Freund's. Paw edema value, spleen and thoracic gland indexes, serum interleukin-1β (IL-1β), and nitric oxide (NO) were observed. Results: Both Simiao Pills with crude Atractylodis Rhizoma and bran stir-baked Atractylodis Rhizoma could inhibit paw edema, decrease spleen index, advance the thoracic gland index, and decrease IL-1β and NO. The Simiao Pills with crude Atractylodis Rhizoma showed better effects. Conclusion: Both Simiao Pills with crude Atractylodis Rhizoma and bran stir-baked Atractylodis Rhizoma show a certain therapeutic effect on adjuvant arthritis, but the crude Atractylodis Rhizoma is in favor of the efficacy of Simiao Pills.

Objective To make clear the relationship between the genetic polymorphism of MMP-1 and implant early failure.Methods We conducted a case control study,53 cases patients (no smoking history and without periodontitis) who have underwent dental implant were divided into experimental group(with dental implant failure) and control group(with dental implant success) according to early failure of dental implant (within one month).DNA of 53 patients in Han nationality were extracted by using Chelex-100 method and polymorphisms of the mmp-1-1607 gene were detected by restriction fragment length polymorphism after polymerase chain reactions.Results Patients with MMP-1-1607(1G/2G) genotype exhibited a significantly higher occurrence of implant early failure than those with MMP-1-1607(1G/1G) gene type(P＜0.05).The OR of the 1G/2G versus the 1G/1G of the MMP-1-1607 genotype was 13.894(P＜0.05).Conclusion MMP-1-1607(1G/2G) genotype is associated with implant early failure.

Objective:To investigate the clinical application and adverse events of vinpocetine injection. Methods:The application of vinpocetine injection in the patients in neurology department during December 2013 and December 2014 in a hospital was statistically analyzed. The adverse reactions of the injection reported in the professional literatures and relevant documents were also retrieved and statistically analyzed. Results:The infusion concentration of vinpocetine injection for 363 patients was more than 0. 06 mg·ml -1 ,and 3 cases of adverse reactions appeared with the main symptoms of rash and drug fever. Among 28 published literatures,19 articles were with the infusion concentration of vinpocetine injection above 0. 06 mg·ml-1 and 8 articles reported adverse reactions in varying degrees. Conclusion:Clinicians should pay attention to the instructions in the clinical course of medication in order to improve the safe and rational use of drugs.

Objective To evaluate the efficacy and safety of disodium cantharidinate injection combined with transcatheter arterial chemoembolization(TACE) compared with TCAE alone in the treatment of hepatocellular carcinoma(HCC) by meta-analysis.Methods Databases of Pubmed, CNKI,Wangfang and VIP were searched electronically, and the randomized controlled trials about disodium cantharidinate injection combined with TACE in the treatment of HCC were included.Meta-analyses were conducted after the quality of the included studies was assessed.Results Seven eligible studies that included a total of 562 HCC patients were identified in the present meta-analysis.The combined results showed that disodium cantharidinate injection combined with TACE in the treatment of HCC, compared with TACE alone, could increase effective rate ( RR =1.31, 95%CI 1.10-1.56) and clinical benefit rate (RR =1.20, 95%CI 1.04 -1.39), improve the life quality (RR =1.60, 95%CI 1.26 -2.03) and improved the 1, 2 year survival (RR =1.57 with 95%CI 1.28 -1.93 and RR =2.08 with 95%CI 1.46 -2.97, respectively).Conclusion Meta-analysis indicates that the efficacy of disodium cantharidinate injection combined with TACE is superior to TACE alone for the patients with HCC.

The concentration of osteopontin (OPN)in serum of patients with oral squamous cell carcinoma(n=58),benign maxillofacial tumor(n=45)and healthy controls(n=60)was examined using ELISA kit.The OPN level(ng/ml)in the 3 groups was 1 61 .8 ±1 2.6, 52.3 ±8.6 and 48.6 ±1 2.8(P<0.05)respectively,the cases with nodal metastasis and late clinical stage have relatively higher expression levels of OPN(P<0.05).Serum OPN may be related to OSCC progression.

Aim To investigate the expression of CD31 , CD105 , HIF-1αand VEGF in xenografts tumor of HT-29 tumor cells during different stages of growth. Methods HT-29 tumor cells were transplanted into nude mice, the tumor was removed when the tumor volumes reached <100 mm3 , 100 ~300 mm3 and >300 mm3 respectively. Immunochemical method was a-dopted to detect the expression of CD31 , CD105 , HIF-1α and VEGF. Results HT-29 xenografts tumor vol-umes <100 mm3 , 100 ~300 mm3 , and >300 mm3 showed expressions with CD31-MVD at 37.40±4.17 , 18.80±1.72 and 14.20±2.23 respectively; CD105-MVD at 22.80 ±3.54 , 15.60 ±1.35 and 10.20 ±2.48; positive expression rate of VEGF was 26.20%
±0.83%,40.73% ±6.29% and 13.41% ±1.20%respectively; while positive expression rate of HIF-1αwas 3.20% ± 2.97%, 11.89% ± 1.94% and 80.62% ±3.47% respectively. On the other hand, for different volumes group, CD31-MVD, CD105-MVD, VEGF and HIF-1αexpression ratios had signifi-cant differences ( P <0.01 ) . Conclusions The ex-pression of MVD and vascular-related factors within the tumor caused by HT-29 xenografts tumor in nude mice at different growth stages was varied. There was a cer-tain correlation between tumor volume and MVD, VEGF, HIF-1α.
