This article is based on the searching from the United States Library of Congress Web Search science 2005 for the literature on the birth femoral fractures,reviewing its incidence,pathogenesis and treatment of such fractures of the latest developments,for the purpose of the provision of orthopedic and obstetric physician reference.Literature showed that neonatal birth femoral fractures might occur whether deli-veries were through the birth canal or by cesarean section.Whenever faced with fetal asphyxia,intracranial hemorrhage,such as critical state,it is critical to save the life of fetal babies,regardless of treatment.The prognosis of neonatal femoral shaft fractures is normally good without deformity left.

More than ten bacteriophage of E.coli were isolated from the soil and the dung of the fowl-run, then three of named bacteriophage A, C, D which lysis E.coli virulently were selected to investigate biological characterizations. The results showed that high activities were obtained after the phages incubated at 50℃ for 1 h or 60℃ for 30 min. The phages could be alive at the range of pH from 4 to 12, Ca 2+ or Mg 2+ added to the medium could stimulate the lysis of phages. However, the formation of the plaque could be inhibited obviously by adding sodium citrate to the medium.

Objective:To investigate the role of transcription factor SP1 decoy oligodeoxynucleotides(ODN) on expression of ? Gal in SV-40-PED cells.Methods:Immortalized porcine aortic endothelial cells of the PED line were cultured and transfected with ?1,3galactosyltransferase(?1,3GT) specific decoy ODN.Cells transfected with mismatch ODN was used as negative controls.Twenty-six hours later the cells were collected.The expression of ? Gal was determined with fluorescence microscope and Western blot.The expression of ?1,3GT mRNA was examined by RT-PCR.Results:Fluorescence microscopy observed the decreased fluorescence of ? Gal after decoy ODN transfection.Western blot showed that the average absorbance of the PED cells transfected with decoy ODNs was(48.2?0.9).It is 52.6% of the mock group(P0.05).Conclusion:?1,3GT gene reduce actually occurs following transfection of decoy ODN.Porcine endothelial cells can be the targets of decoy ODN.

Objective To describe CT manifestations of intrahepatic spontaneous portosystemic shunts(ISPS) of cirrhosis.Methods Spiral CT(SCT) scans and related clinical findings of 15 cirrhotic patients with ISPS were retrospectively reviewed.Results Three kinds of ISPS were showed :①Right posterior portal vein type was in 12 cases and showed tortuous intrahepatic tubular structures which were all in the posterior segment of the right lobe connecting the right posterior portal vein to the inferior vena cava(IVC) in the suprarenal region in all cases.②Hepatic venous type was in 2 cases,the portal vein communication with the hepatic vein in the liver.③Apex type was in 1 case,the vein arose from the apex of the liver and drains into the internal thoracic vein.Blood ammonia levels were elevated in all cases and symptoms associated with hepatic encephalopahty were present in 2 cases.Conclusion To deeply understand the ISPS,it is of benefit for differential diagnosis of focal hepatic lesions.

Objective: To compare the efficacy difference between moxibustion at sensitized-acupoints and non-sensitized- acupoints using the same group of acupoints. Methods: A total of 139 patients with chronic superficial gastritis were divided into a sensitized acupoint group (102 cases) and a non-sensitized acupoint group (37 cases) based on whether acupoint sensitization occurred. The SPSS version 19.0 statistical software propensity score matching function was used to balance the baseline data between the groups. Finally, 29 pairs of matched patients were included, namely 29 cases in the sensitized acupoint group and 29 cases in the non-sensitized acupoint group. Both groups were treated with moxibustion therapy. The treatment lasted for 30 min per time, and was performed every other day for 8 weeks. Changes in the traditional Chinese medicine (TCM) symptom score and the short-form 36-item health survey (SF-36) score in both groups were observed before and after treatment, as well as the clinical efficacy. Results: The covariates of age, course of disease, TCM symptom score and SF-36 score in the two groups were balanced after matching (all P>0.05). After treatment, the total effective rate was 100.0％ in the sensitized acupoint group and 79.3％ in the non-sensitized acupoint group. The difference in the total effective rate between the two groups was statistically significant (P<0.01). After treatment and at the 4-week follow-up, the TCM symptom scores in the sensitized acupoint group were significantly lower than those in the non-sensitized acupoint group (all P<0.01); the SF-36 scores in the sensitized acupoint group were significantly higher than those in the non-sensitized acupoint group (all P<0.01). Conclusion: With the same group of acupoints, the sensitized acupoints have a better therapeutic effect and long-term efficacy than the non-sensitized acupoints in the treatment of chronic superficial gastritis.

AIM: To screen TIGR/myocilin gene (MYOC) mutation in high myopic Chinese children with family history.METHODS: Gene sequencing was performed in exon 3 of the TIGR gene in high myopic Chinese Children. The coding sequence of TIGR exon 3 was screened by capillary electrophoresis sequencing. The sequence alterations were analyzed by bioinformatics.RESULTS: TIGR gene mutation was not found in high myopic patients and normal controls group.CONCLUSION: No identified gene mutation is found in TIGR gene in high myopic Chinese children.

Objective To study the occurrence site characteristics of middle cerebral artery aneurysm (MCAA ) in volume CT digital subtraction angiograhy(VCTDSA) .Methods The image characteristics in 72 cases of MCAA from May 2009 to January 2011 were retrospectively analyzed ,according to the running of middle cerebral artery ,the occurrence sites of aneurysm were divided into four categories :M1 segment ,M2 bifurcation ,M2 distal and M3-M5 segment ,the aneurysm number was conducted the statistics and the image characteristics were analyzed ;two neuroradiologists adopted the double-blind method to measure the MCAA angle in bifurcation of M2 segment and compared it with the bifurcation angle in the normal middle cerebral artery ,the difference between them were statistically analyzed .Results (1)M1 segment aneurysms were 7 cases(9 .70% ) ,M2 bifurcation aneurysms were 58 ca-ses(80 .56% ) ,M2 distal aneurysms were 5 cases(6 .94% ) and M3-M5 segment aneurysms were 2 cases(2 .78% ) .(2)The angle in M2 bifurcation of the normal middle cerebral artery was(99 .30 ± 22 .96)° ,M2 bifurcation aneurysm angle was(139 .26 ± 27 .61)° , the difference between them showing statistical significance (P<0 .01) .(3)The difference between left and right of M 2 bifurcation angle in the normal middle cerebral artery had no statistical significance (P>0 .05) .(4)The M2 bifurcation angle in ruptured aneu-rysm was(133 .98 ± 30 .24)° ,which in unruptured aneurysms was(144 .53 ± 21 .81)° ,the difference between them had no statistical significance(P>0 .05) .Conclusion MCAA mainly occurred in M2 bifurcation .There is significant difference in M2 bifurcation an-gle between the aneurysm group and non-aneurysm group ,M2 bifurcation angle is increased ,the probability of aneurysm occurrence is increased .

Objective To explore the clinical effect and application value of four-point internal fixation technique (internal fixation of C_1-C_2 transarticular screws combined with Apofix laminar clamp technique) for traumatic atlantoaxial instability.Methods A total of 16 patients with traumatic atlanto- axial instability,who had reducible atlantoaxial dislocation with reduction after traction and irreducible at- lantoaxial dislocation with traction reduction after anterior laxation,were treated with four-point internal fixation technique using autologous bone grafts.Results All patients' symptoms were improved to some extent,and no severe complications,such as injury of nerve blood vessels were found.All patients were followed up for 8-26 months (average 16 months).Bony fusion was obtained in all cases.The spinal cord function improvement was marked in 5 cases (31%),good in 8(50%),mild in 2(13%),but un- changed in 1 (6%).No deterioration occurred in all cases.There was no loosening or breakage of screws and clamps.Conclusion Fixation of C_1-C_2 transarticular screws combined with Apofix laminar clamp technique can atlain four-point internal fixation,and can provide three-dimensional stability of atlantoaxial complex and excellent biomechanics environment for bony fusion if the structure of the posterior arch of C_1-C_2 is intact.
