Objective:To investigate the effects of Adp53 and F56 on the growth and lung metastasis of breast cancer.Methods:The BICR-H1 cells were inoculated into the mammary fatty pad of BALB/C nude mice and NOD/SCID mice to establish breast cancer model.Then the nude mice with xenograft tumor were randomized into group Adp53+F56,Adp53,F56 and control.The NOD/SCID mice with xenograft tumor were randomized into group Adp53+F56,Adp53,F56,Adlacz and control.They were theated for 3 weeks according to the plan,diversity of the volume and histopathology of xenograft tumor of nude mice was observed and the expressions of p53 and VEGF gene,and microvessel density(MVD)were detected by immunohistochemistry.Lung metastasis of breast cancer in NOD/SCID mice was observed.Results:(1)Intratumoral injections of Adp53,F56,and their combination resulted in an inhibition on the growth of xenograft tumor of BICR-H1 cells.The ultimate relative growth volumes of groups Adp53+F56,Adp53,F56 and control were 2.47,4.37,4.69 and 12.49 respectively.(2)After treatment,P53 positive rate of group Adp53+F56,Adp53 increased 9.4%,6.3% than before respectively,but compared with control group,the difference is not significant(P=0.693);VEGF protein of group Adp53+F56,Adp53 and F56 decreased 21.9%,9.4% and 3.1% than before respectively,but compared with control group,the difference was not significant(P=0.284).Necrosis and decrease of vessel in the tumor and morphological change of endothelium were observed under light microscope in the groups Adp53+F56,Adp53 and F56.MVD estimated by FⅧ-RA staining of group Adp53+F56,Adp53 and F56 were 14.50?2.54,16.28?3.44 and 18.06?7.66,compared with control group(24.93?6.53),the difference is significant(P=0.000).(3)The average number of lung metastasis of NOD/SCID mice in group Adp53+F56,Adp53 and F56 were 1.143?0.378,2.750?0.886 and 3.375?0.518 respectively,lower than Adlacz group(5.000?0.816)and control group(5.670?0.817)obviously(P=0.000).Conclusion:Adp53 combined with F56 can greatly inhibit growth and matastasis of breast cancer in vivo.The mechanism of anti-tumor effects of Adp53 and F56 may be related to the anti-angiogenesis effect on malignant tumor through inhibiting the expression and activity of VEGF.

Based on the structure and function of acupoint and in association of the definition and principle of sensor, the acupoint is the sensitive element, being sensitive to the physical stimulation with acupuncture and moxibustion and sensitively responded to the disorders; the acupoint is the sensing element, transforming the changes of the acupoint information via the complicated internet conduction, integration and regulation, so as to generate the effects on organic body; the acupoint is the conversion element, transforming every irritation into the bioelectric signal or optical signal so that the organic body could recognize it. Therefore, the acupoint is regarded as the sensor of information in the organic body.

OBJECTIVETo explore clinical effects of suturing-assisted locking plate in treating elderly proximal humeral fractures.

METHODSFrom January 2005 to January 2013, 55 elderly patients with three- and four-part fractures of proximal humeral fractures were divided into treatment group and control group. In treatment group, there were 31 patients including 12 males, and 19 females aged from 65 to 85 with an average of (74.00±5.42) years old, and treated with suturing-assisted locking plates; 19 patients were Neer 3-part fractures, and 12 patients were Neer 4-part fractures of proximal humerus; 23 patients were suffered from low-energy injuries and 8 patients were caused by high-energy injuries. In control group, there were 24 patients including 7 males, and 17 females aged from 65 to 85 with an average of (72.79±5.34) years old, and treated with locking plates; 16 patients were Neer 3-part fractures, and 8 patients were Neer 4-part fractures of proximal humerus; 17 patients were suffered from low-energy injuries and 7 patients were caused by high-energy injuries. Operative time, blood loss during operation, and bone healing time between two groups were observed and compared. Postoperative Neer scoring were used to evaluate recovery of shoulder joint function.

RESULTSAll patients were followed up from 6 to 24 months with an average of 16.1 months. In treatment group, blood loss was (495.806±143.150) ml, function of Neer scoring was 22.645±2.443, range of action was 18.194±2.613, anatomy was 7.935±1.504 and total score of Neer scoring was 77.161±8.335; while in control group, blood loss was (641.667±169.851) ml, function of Neer scoring was 13.958±1.989, range of action was 13.083±2.165, anatomy was 5.500±1.978 and total score of Neer scoring was 58.792±7.313. There were sigificant difference between two groups in these indexes.

CONCLUSIONSuturing-assisted locking plate for the treatment of proximal humerus fractures in elderly, has advantages of less blood loss, simple fracture reduction and rapid recovery of shoulder joint, and is a effective method.

OBJECTIVETo investigate the relationship between tobacco smoking, drinking and p53 alteration in esophageal carcinoma.

METHODSLiterature on the relationship between p53 alteration in esophageal carcinoma and tobacco smoking, drinking through Meta-analysis were reviewed.

RESULTSIn 14 selected papers related to tobacco smoking, pooled odds ratio (OR) of tobacco smoking with P53 overexpression and p53 alteration were 1.99 (95% CI: 1.30- 3.06) and 1.64 (95% CI: 1.13 - 2.37), respectively (P < 0.05). Pooled OR of tobacco smoking with p53 mutation was 1.11 (95% CI: 0.47 - 2.76) (P > 0.05). In 11 selected papers on alcohol drinking, pooled OR of drinking with P53 overexpression, p53 mutation and p53 alteration were 1.30 (95% CI: 0.83 - 2.04), 1.13 (95% CI: 0.67 - 1.90) and 1.22 (95% CI: 0.87 - 1.72) respectively (P > 0.05).

CONCLUSIONThere were significant relations between tobacco smoking and p53 alteration while there were no significant relations between alcohol drinking and p53 alteration.

OBJECTIVETo compare the differences in mental health state and psychological capacities between Chinese college students with and without siblings.

METHODSThe psychological status and capacities were evaluated with SCL-90, the Self-Esteem Scale, Spheres of Control Scale, Security Questionnaire and Cattell 16-PF Questionnaire in 427 college students, and among the students who presented valid responses, 139 with and 139 without siblings were selected for this comparative study.

RESULTSThe total score and average score of SCL-90 in college students without siblings were significantly lower than those in students with siblings (P<0.05); the scores of factors C, E, and F of 16-PF were significantly higher but the score of factor O significantly lower in the former group (P<0.05). The scores of certainty in control, interpersonal security and total score of security were significantly higher in the students without siblings (P<0.01).

CONCLUSIONThe mental health state and some of the psychological capacities are generally better in college students with siblings than in those without siblings.

The borneol was included with β-CD and prepared Fufang Danshen intestinal adhesion pellets. GC method for determination of borneol in Fufang Danshen intestinal adhesion pellets was established to study its in vitro dissolution and make a comparison with the Fufang Danshen tablet, in this way, the rationality of dosage form was evaluated. The first method of dissolution determination was used for determining the in vitro dissolution of borneol in Fufang Danshen intestinal adhesion pellets in artificial intestinal juice, and Fufang Danshen tablet in artificial gastric juice and intestinal juice, respectively. Result shows: the concentration of borneol in Fufang Danshen intestinal adhesion pellets and Fufang Danshen tablet was 0.79% and 0.80%, respectively. Its in vitro dissolution was nearly 70% within 12 h in Fufang Danshen intestinal adhesion pellets, and in Fufang Danshen tablet, the dissolution was about 60% within 20 min and more than 90% within 40 min, and in artificial gastric juice, was less than 20% within 40 min but more than 80% till 150 min. Research suggests that in comparison with Fufang Danshen tablet, in vitro dissolution of borneol in the Fufang Danshen intestinal adhesion pellets showed an obvious sustained release behavior. The borneol in Fufang Danshen intestinal adhesion pellets was included with β-CD and prepared enteric preparations. To some extent, the stimulation on stomach and intestinal mucosa can be reduced and safety can be improved.
