BACKGROUND:Critical limb ischemia is difficult to be treated among the peripheral arterial occlusive diseases, and the application of transplanting autologous stem cells can bring a hope for the treatment of this disease.
OBJECTIVE: To review the autologous stem cells transplantation in the treatment of critical limb ischemia at present, and to study the mechanism and the existing problems.
METHODS:A computer retrieval of PubMed database, Wanfang database, and CNKI database was conducted to search the related articles with the keywords of“stem cell, transplant, critical limb ischemia”in English and Chinese. Final y, 47 articles were included in final analysis according to the inclusion criteria.
RESULTS AND CONCLUSION:Autologous stem cells transplantation for treatment of lower extremity ischemic disease is a latest and significantly effective treatment, but the mechanism is unclear and stil needs further study.

Objective To explore the impact on rabbit intestinal mucosa injury and the influence on endoscopic operation with different temperatures of water infusion. Methods 30 common adult male rabbit (weight 1.6~2.5 kg), were randomly divided into three groups with different temperatures of water infusion as follows:A group (35~36℃), B group (37~38 ℃), C group (39~41 ℃), then, perform water infusion colonoscopy, evaluating the operators satisfaction, then we observe the pathological changes of postoperative intestinal mucosal tissue. Results There was no statistically significant difference among the three groups of intestinal mucosa injury ( > 0.05). The vision exposure score of Group C was lowest, compared with the other two groups, which has a statistically significant differences ( < 0.05). Conclusions Warm water infusion colonoscopy is a safe and effective method, and the optimum temperature was about 39~41℃.

OBJECTIVE: To investigate the relationship between visceral syndrome differentiation in traditional Chinese medicine (TCM) and the changes of nutrition status or blood gas analysis in patients with chronic obstructive pulmonary disease (COPD). METHODS: Sixty patients with COPD in stable phase were divided into dysfunction of lung (DL, n=20) group, dysfunction of lung and spleen (DLS, n=16) group and dysfunction of lung, spleen and kidney (DLSK, n=24) group according to syndrome differentiation of TCM. Moreover, the basic electric rhythm, percentage of bradygastria in electrogastrogram (EGG), ratio of actual body weight (ABW) to ideal body weight (IBW) and serum albumin level were determined to evaluate the nutrition status of the patients with COPD. Blood gas analysis was made too. RESULTS: The basic electric rhythm values in the DL, DLS and DLSK groups were (56.20+/-13.24)%, (47.38+/-10.24)% and (41.35+/-10.01)%, respectively. Compared with the DL group, the basic electric rhythm values in the DLS and DLSK groups decreased obviously (P<0.05). The percentages of bradygastria in the DL, DLS and DLSK groups were (45.18+/-18.13)%, (46.31+/-15.83)% and (49.90+/-17.54)%, respectively, and there were no differences among the three groups (P>0.05). The incidence rates of ABW/IBW<90% in the DL, DLS and DLSK groups were 50%, 75% and 54.17%, respectively, and there were no differences among the three groups (P>0.05). The incidence rates of serum albumin less than 35 g/L were 20%, 37.5% and 54.17%, respectively, and there were no differences among the three groups (P>0.05). PO2 in the DLS group [(63.56+/-15.06) mmHg] and DLSK group [(63.17+/-19.05) mmHg] were decreased as compared with the DL group [(78.15+/-16.63) mmHg] (P<0.05). PCO2 in the DL, DLS and DLSK groups were (42.25+/-12.46) mmHg, (48.60+/-17.60) mmHg and (49.97+/-13.43) mmHg respectively, and there were no differences among the three groups (P>0.05). CONCLUSION: Several dysfunction organs described in TCM were involved in COPD followed by the increased severity, hypoxemia and PCO2. Dysfunction of gastrointestinal tract and malnourishment took place accordingly.

Objective To study the correlation of artery stiffness with left ventricular remodeling and cardiac function in coronary heart disease (CHD) patients .Methods Four hundred and eighty patients were divided into CHD group (n=373) and non-CHD group(n=107)according to their coronary angiography .Patients in CHD group were further divided into normal left ventricular re-modeling group (n=139) and abnormal left ventricular remodeling group (n=243) .Their brachi-al-ankle pulse wave velocity (BaPWV ) was measured .The patients underwent echocardiography and 42 patients in CHD group received Doppler tissue imaging .Results The BaPWV was signifi-cantly higher in CHD group than in non-CHD group (P<0 .01) and in abnormal left ventricular remodeling group than in normal left ventricular remodeling group (1689 ± 305 cm/s vs 1508 ± 280 cm/s ,P< 0 .05) .The BaPWV was positively related with the IVST ,PWT ,RWT ,LVMI ,E/Ea and negatively related with the LVEF ,Ea ,Ea/Aa in CHD group (P<0 .05 ,P<0 .01) .Partial cor-relation analysis showed that the BaPWV was significantly related with the IVST ,PWT ,RWT , LVMI ,LVEF ,Ea ,Ea/Aa and E/Ea when the effect of hypertension ,etc ,was excluded (P<0.01) .Multivariate regression analysis demonstrated that the BaPWV was an independent factor for LVMI and LVEF .Conclusion BaPWV is an independent factor for left ventricular remodeling and cardiac function in CHD patients .

Objective To explore the effects of warm water insufflation applied in difficult colonoscopy on its success rate, insertion time, operation difficulty level and tolerance of patients. Method 200 cases of the difficult defecation of non-narcotic colonoscopy, IBS and always has a history of pelvic/abdominal surgery patients, were randomly divided into warm water infusion group (experimental group) and traditional method of air insufflation group (control group), then compare the differences of the success rate of the two groups of patients, the insertion time and degree of tolerance in patients. Results All the patients completed the investigation in this study, neither bowel perforation nor other complications occurred. Experimental group success rate of the whole colon examination, the insertion time, the operator satisfaction and check again wishes were significantly higher than that of control group (P < 0.05). In abdominal pressure and utilization, abdominal pain scoring position transformation, the former was significantly lower than the latter (P < 0.05). In abdominal pressure and utilization, abdominal pain scoring position transformation, the former was significantly lower than the latter (P < 0.05). There is no significant difference (P > 0.05) in Polyp detection rate. Conclusion Warm water insufflation colonoscopy can effectively improve the tolerance and accelerating the colonoscopy in patients with difficult insertion process, improve work efficiency, and is an ideal method, which is worth of promoting.

Objective To study the effect of bone marrow mononuclear cells transplantation on restenosis rate and its mechanism. Methods The left anterior descending coronary arteries of swines were obstructed by balloon to create myocardial infarction models. After 3 weeks coronary stents were implanted at the middle part of the left anterior descending coronary arteries followed by the injection of bone marrow mononuclear cells into the coronary arteries. The degree of restenosis were measure by quantitative coronary angiography (QCA) after four weeks. Vascular tissue at both ends of stents were tested by HE and Sirius staining to analyse the mechanism of restenosis. Results At end of the experiment there were 8 swines in the bone marrow mononuclear cells transplantation group and 9 in the control group. After injection of bone marrow mononuclear cells the restenosis rate was similar to the control group (50% vs 44%, P=0.762). The lumen late loss was also similar between the two groups (1.50?1.45 mm vs 1.31?1.07 mm,P=0.736). Conclusion Bone marrow mononuclear cells transplantation does not increase the restenosis rate after percutaneous coronary artery intervention.

The arsenic compounds including arsenic trioxide and arsenic sulfide have played a crucial role in the clinical treatment of hematologic malignancies and solid tumors. Arsenic agents can induce tumor cells differentiation, apoptosis and autophagy, eliminate leukemia-initiating cells, and directly bind to the target proteins. This paper reviews the mechanism progress of arsenic agents in various tumors to further understand the intricate anti-tumor mechanisms of arsenic agents and to expand its therapeutic spectrum.
