Objective To study the correlation between ?-fibrinogen gene variation (-455G/A) and plasma fibrinogen level and cerebral infarction.Methods 86 hypertension patients with cerebral infarction(infarction group),85 hypertension patients without cerebral infarction(hypertension group) and 90 healthy people(control group) were enrolled in this trial. The polymorphism of ?-fibrinogen gene-455G/A located at the start of transcription from all subjects was analyzed by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) technique. Plasma fibrinogen level was measured with prothrombin time (PT) assay.Results The fibrinogen level in infarction group(4.82?0.26 g/L) was significantly higher than that in control group(4.37?0.19 g/L)( P 0.05).The A-455 allele frequency in infarction group was significantly higher than those in control group and hypertension group (all P 0.05). Conclusion Plasma fibrinogen level is affected by the ?-fibrinogen gene -455G/A polymorphism. The fibrinogen A-455 allele may be an independent risk factor of cerebral infarction.

Objective We aimed to assess the influence of space teaching on junior-college nursing students' autonomous learning ability.Methods Using random number table,two classes of junior-college nursing students of Grade 2012 were selected and divided into the experimental group (46 students) and the control group (47 students) according to their classes.Students in the control group received routine multimedia teaching.Students in the experimental group received space teaching based on the platform of World University City.The effect of space teaching on developing nursing students' autonomous learning ability was assessed with the help of their test results and the nursing students' autonomous learning ability evaluation form.Results After carrying out space teaching,the average grade,theoretical performance,total points,the total score of autonomous learning ability and the score of each dimension in the experimental group and the differences were remarkably higher than those of the control group (t value was 2.80,2.45,2.29 and 11.58).Conclusions Space teaching can assist in arousing nursing students' learning motivation and improving nursing students' independent learning ability.It can be used for reference and promoted.

In both clinical and animal experiments,it has been confirmed that the inflammation in heart is involved in the development of heart injury after the ischemia/reperfusion.However,the pro-inflammatory mechanism is extremely complicated.Recently,a growing number of reports indicates that many factors play their roles in the inflammation,such as cytokinemia,inflammatory cells,metabolic product of arachidonic acid and COX et al.They are released/presented in the region of myocardial ischemia/reperfusion and include both ischemic and secondary heart injury.

For recent two decades,radiofrequency ablation technology has made great progress in the field of the treatment for neoplasm.At the very beginning,radiofrequency ablation was adopted in treating the hepatic carcinoma,and since then it has been gradually practiced in treating malignancies of lung,bone,kidney,breast,prostate and other solid tumors.Statistical report of the year 2008 has indicated that in the aspect of similar therapeutic measures radiofrequency ablation therapy for tumors holds a 9% market share.Moreover,in the coming years the clinical use of this kind of therapy for tumors will be steadily increasing by 13% every year.

The effects of monoterpene perilly alcohol (POH) alone or in combination with STI571 on the proliferation and apoptosis of the cell line K562 positive for Bcr/Abl were investigated. By using cell culture, the effect of the drugs on the proliferation of the cells was studied. TUNEL and flow cytometry assay of FITC-Annexin V and PI labeled cells were applied to detect the effects of the drugs on the apoptosis of the cells. The results showed that at 36 h, IC50 of POH on K562 positive for Bcr/Abl and HL-60 negative for Bcr/Abl were 81.0 +/- 11.3 micromol/L and 113.6 +/- 23.4 micromol/L respectively (P>0.05). POH could inhibit the proliferation of K562 in a time- and dose-dependent manner with the inhibitory rate of 100 micromol/L POH on K562 cells at 36 h being (53.2 +/- 3.65)%. K562 cells were more sensitive to STI571 than POH. IC50 of STI571 on K562 cells in 36 h was (0.256 +/- 0.054) micromol/L. In a time- and dose-dependent manner, POH induced the apoptosis of K562 cells with the percentage of apoptotic cells by 100 micromol/L POH at 40 h being (21.0 +/- 3.3)%. Both 100 micromo/L POH and 0.2 micromol/L STI571 had the same inhibitory effects on the K562 cells at 36 h. But at 12 and 24 h, the inhibitory rate of POH was significantly higher than that of STI571 (P<0.05) and the ability of STI571 inducing apoptosis at 36 h was greater than that of POH. 50 micromol/L, 100 micromol/L and 200 micromol/L POH in combination with 0.2 micromol/L STI571 could obviously increase the inhibitory effects on the cellular proliferation. Combined use of 50 micromol/L, 100 micromol/L, 200 micromol/L with 0.2 micromol/L STI571 could strongly induced apoptosis, especially 200 micromol/L POH in combination with 0.2 micromol/L STI571. It was concluded that the antileukemia effect of POH had no obvious Bcr/Abl positive selectivity. POH can inhibit the proliferation of K562 and induce the apoptosis in a time- and dose-dependent manner. K562 cells were more sensitive to STI571 than POH. POH in combination with STI571 could obviously enhance the abilities of STI571 inhibiting the proliferation and inducing apoptosis of K562 cells.

BACKGROUND: The improvement in production technology of new materials including artificial ligament reduces material rupture caused by fatigue and histocompatibility-related synovitis and other complications, leading to a wide application of artificial ligament. OBJECTIVE: To evaluate the histocompatibility and clinical curative effects of reconstruction of the anterior cruciate ligament (ACL) of the knee with ligament advanced reinforcement system (LARS) artificial ligament using arthroscopy. DESIGN: A completely randomized clinical design. SETTING: Department of Orthopedics, Second Affiliated Hospital of Soochow University. PARTICIPANTS: Thirty-two cases of ACL injury received LARS artificial ligament in the Department of Orthopedics, Second Affiliated Hospital of Soochow University From June 2005 to June 2006 and were recruited for this study. The 32 patients averaged 21 years old and were injured in sports. Prior to surgery, MRI showed injury to ACL and semilunar valve in all patients. Written informed consent for therapeutic contents was obtained from each patient. METHODS: Thirty-two patients with injury to ACL of the knee underwent arthroscopic ACL reconstruction. LARS was used to reconstruct the ACL. The LARS was produced by Laboratoire d'Application et de Recherche Scientifique, France (Certification No. CE0459, 1SO9002-EN46002). Artificial ligament was made of polyethylene terephthalate, which had the material type L021201 (left knee) and L021202 (right knee). Artificial ligament was designed to imitate the anatomic structure and biomechanical principle of artificial ligament with specification No. AC120 2BL(left knee) and No. AC120 2BR(right knee). The lot number for artificial ligament in China [import 03460468 (in 2004)]. All reconstructions were performed by a group of physicians who have worked for more than 10 years in the Department of Orthopedics, Second Affiliated Hospital of Soochow University and directed by a physician titled with doctor's tutor and chief physician. All included physicians were qualified to perform the surgery. The protocol of treatment was approved by the hospital's Ethics Committee. MAIN OUTCOME MEASURES: Biocompatibility of LARS artificial ligament was observed. Patients were followed up for 24 months on average to score knee function by Lysholm test and subjective satisfaction by Tegner test. RESULTS: All of 32 cases were followed up. The follow-up periods were 18 months (3 cases), 20 months (7 cases), 24 months (8 cases), 28 months (12 cases) and 30 months (2 cases). No complications, such as acute or chronic synovitis, LARS artificial ligament rupture, or limited range of motion were found. The knee joint function was ideal with the range of motion [0° to (128±11.56)°]. The postoperative scores with 85.6 ± 2.24 were significandy higher than the preoperative scores with 45.3±1.31 according to the Lysholm knee joint function evaluation system (P < 0.05). The instability of every knee disappeared with anterior drawer sign negative. Tegner's scores were also increased. CONCLUSION: The biocompatibility of LARS is optimal. LARS artificial ligament reconstruction showed excellent knee joint function and subjective satisfaction degree.
