Methods A single-center, prospective, randomized, controlled study method was used, 84 patients with breast benign lesions were randomly divided into observation group and control group, 42 patients in each group. Patients in the observation group were treated with ultrasound guided minimally invasive rotary cutting, patients in control group were treated with traditional surgery. The intraoperative and postoperative related indicators were compared between two groups. Results The intraoperative blood loss, length of incision, operation time in breast benign unilateral single and unilateral and bilateral lesions in the observation group were significantly less than those in the control group, with statistically significant difference (P<0.01) . The healing time, postoperative pain score, complications in breast benign unilateral single and unilateral and bilateral lesions in observation group were less than those in the control group, with statistically significant difference (P<0.01) . And the postoperative satisfaction, and the excellent rate of beauty in breast benign unilateral single、unilateral and bilateral lesions were better than control group, with statistically significant difference (P<0.01) . There was no breast deformation in observation group after treatment, and there were 3 patients of breast deformation in the control group has 3 patients, accounting for 7.14%. Conclusion Ultrasound guided minimally invasive rotary cutting is significantly superior to the traditional treatment in security and effectiveness for treatment of breast benign lesions in one single and unilateral multiple and bilateral lesions.

Objective To study the relation between coagulation-fibrinolysis and metastasis, hormone receptor and TNM stage of breast cancer. Methods The plasm levels of six coagulation-fibrinolysis indexes of 30 breast cancer patients were tested, which included activated partial thromboplastin time(APTT), fibrinogen(FIB), D-dimer(D-Di), tissue type plasminogen activator (t-PA)and plasminogen activator inhibitor-1(PAI-1). Statistic analysis of the relation between the changes of these indexes and metastasis, hormone receptor and breast cancer cell proliferation was performed. Results There were statistically significant differences between the malignant and benign breast disease in FiB(3.05±0.44)g/L vs(3.39±0.52)g/L(P＜0.05),D-Di(0.27±0.06)μg/ml vs(0.36±0.16)μg/ml(P＜0.05) and PAI-1(26.14±3.30)ng/ml vs(34.59±3.68)ng/ml (P＜0.01). The levels of plasma FIB (3.70±0.47)g/L and PAI-1 (37.36±2.71)ng/ml in metastasis group were higher than those in the non-metastasis group (P＜0.01). Significantly higher levels of PAI-1(36.40±3.57)ng/ml(P＜0.05)in expression of Ki67≥30% in the patients with lymph node involvement were seen. Conclusion Coagulation-fibrinolysis indexes were related to the proliferation, invasion, metastasis and clinical stage of breast cancer and it can serve as an important marker for predicting breast cancer's biological behavior and prognosis.

Progress in the metacarpophalangealgeal joint implantation has drawn increasing attention to its role in treatment of chronic arthritis of the hand. This paper summarizes the biomechanic research and devolvement of the prosthesis, preoperative evaluation and plan for metacarpophalangealgeal joint implantation and the clinical results of different designs of the MCP prosthetic joint in the past decade. With improvement of prosthesis designs and operative technology, the MCP implantation will play a better role in clinical treatment of chronic arthritis of the hand, such as relief of pain, rectification of abnormality and functional recovery of the hand.

BACKGROUND: The articular surface of interphalangeal joint and metacarpophalangeal joint is destroyed or defected, that would remain serious sequela in many patients and affect patient's routine work and living. Therefore, therapeutic efficacy of finger joint damage determines the functional recovery of hands. Tissue engineering provides a novel pathway for finger joint damage. OBJECTIVE: To summarize the research progress on the repair and reconstruction of finger joint damage. RETRIEVAL STRATEGY: The researcher of this article used the computer to retrieve literatures of Pubmed database with docuterms of "Interphalangeal joints fractures, Metacarpophalangeal joints fractures, Finger osteoarticular, Reconstruct", and the language was defined to English. Meanwhile China Academic Journals Full-Text Database from 2000 to 2007 was also retrieved with docuterms of "Interphalangeal joints, Metacarpophalangeal joints, Fractures, Repair and reconstruct", and the language was defined to Chinese. Totally 106 correlated articles were screened out and the data were firstly checked. Inclusion standard: ①closely correlated to the repair and reconstruction of finger joint damage; ②those published in the near future or authorized journal in the same field were preferred. Exclusion standard: repetitive investigation. LITERATURE EVALUATION: The resource of literatures was the clinic empirical studies of the repair and reconstruction of finger joint damage. Among 32 included articles, 3 of them were reviews and the others were clinic or empirical studies. DATA SYNTHESIS: The homogeneity variant bone-joint transplantation has got some successes in clinic, but how to prolong the survival time of transplanting joints would be a new research topic. Autoallergic joint transplantation is a good method to treat the defects of finger joints, but how to make handling conveniently, diminish secondary damage and search new donor site, all deserve to research. The ideal therapeutic efficacy of the finger joint damage is anatomical reset of the joint profile, that can reduce traumatic arthritis and anchylosis at the minimal level. But it is still a tough problem in the fingers joint's repairs, because of the multiple structure of bone-joint in hands and trauma factors. Open reduction and internal fixation, skeletal traction, arthroplasty, fusion of joint, prosthetic replacement of joint, articular transplantation and bone-joint tissue engineering have all obtained success, but none can fully succeed or be generally adopted. CONCLUSION: There are many treatments of the finger joint damage, but their results are not very well. With the research of homogeneity variant bone-joint transplantation, autoallergic joint transplantation and tissue engineering development, bone-joint transplantation will have a wide prospect in treatment of finger joints damage.

Objective To understand the cue-induced craving, physiological reactions to heroin-related cues, and to explore the factors that impact the cue-induced craving. Methods 369 abstinent heroin addicts were exposed to videotapes of heroin using and simulacrum after the self relaxation. The craving, abstinent symp-toms were measured before and after cue exposures. The physiological reactions were measured by multi-biofeed-back instrument before, during, and after cue exposure. BIS-Ⅱ questionnaire was used to collect information about their impulsive characteristic. Results After cue exposure, the self-reports scores of craving (t=11.24, P< 0.01), physiological index including heart rate((76.6±11.3) beats/min, F=19.23), skin conduct ((7.48± 4.25)μs, F=53.99), pupil size (t=11.73) had significant change in heroin addicts (P<0.01). Logistic regres-sion results showed that the scores of BIS-Ⅱ were related to cue-reduced craving (P=0.001,95% CI: 1.015～1. 065). Conclusions Exposure to drug-related cues can induces craving and physiological reactions in long term abstinence heroin addicts. High impulsive characteristic is a risk factor to induce drug-related craving. The inter-vention strategies should consider the impulsive characteristic and make a comprehensive intervention program to prevent relapse.

Objective To investigate the relationship between diameter and drainage territory of tributaries of the hepatic vein and the clinical value of hepatic venous drainage territory evaluation before LDLT.Methods MSCT covering abdomen was performed on 68 donors.The images were transported and reconstructed in GE Advantage Windows 4.2 workplace and IQQA-liver CT images readout and analytical system.The tributaries of hepatic vein were marked,and the diameter and drainage territory were measured.Functional hepatic volume (FHV),and effective hepatic volume (EfHV) of donors and recipients according to the hepatic venous reconstruction results during the operation were calculated.The corresponding graft-to-recipient body weight ratio of recipients was calculated.Results In the tributaries of 220 hepatic veins studied,the coefficient correlation of diameter and drainage territory was 0.752 (P≤0.01),but there was significant difference in the drainage territory of the veins with same diameter.By using Chi-square analysis,venous diameter and drainage territory are classified and statistical frequency by 5 mm and 50 cm3 respectively,and there was statistically significant difference between them (X2 =61.97,P＜0.01).The mean value of drainage territory of RHV (RHVV) was 510.80 ± 168.33 cm3,and that of RFHV (drainage territory with reconstructed IRHV added) was 577.26± 156.72 cm3 respectively.The mean value of drainage territory of LHV (LHVV) was 292.70 ± 76.61 cm3,and that of LFHV (drainage territory with Ⅳ segment tributaries of MHV added) was 551.26 ± 111.82 cm3 respectively.In 25 grafts without MHV,the mean value of drainage territory of EfHV was 405.52-1038.43 cm3.In 43 donors donating grafts with MHV,the mean value of drainage territory of EfHV was 175.35-575.35 cm3.Conclusion There is significant difference in drainage territory of same diameter veins.Bigger diameter doesn't always mean bigger drainage territory.Hepatic vein drainage territory evaluation before LDLT has important clinical significance to formulate surgery scheme.
