BACKGROUND:Heart transplantation is an effective method for treatment of end-stage heart failure, but immune rejection that seriously impact therapeutic effacicy is easy to occur after transplantation. OBJECTIVE:To investigate the regulatory effect of bone marrow mesenchymal stem cel s on the immune function of rats undergoiong heart transplantation. METHODS:Twenty Lewis rats were enrol ed as donors, and 20 Wistar rats as recipients. Heart transplantation models were established in the Wistar rats. These 20 model rats were randomized into cel transplantation and control group with 10 rats in each group. Forty-eight hours after heart transplantation, rats in the cel transplantation group were given bone marrow mesenchymal stem cel suspension (1 mL, 2×108 cel s/L) via the tail vein, while rats in the control group were given normal saline in the same dose. Then, the expression levels of serum interleukin-2, interleukin-10 and percentage of CD4+, CD8+, CD4+/CD8+, CD4+CD25high, CD4+CD25high Foxp3+T cel s in the venous blood were detected in the two groups at 7 days after cel transplantation. Additional y, rat myocardial tissues were taken and observed pathological y. RESULTS AND CONCLUSION:The survival time of the cel transplantation group was significantly longer than that of the control group (P<0.05). The expression level of interleukin-2 showed no significant difference between the two groups (P>0.05), but the level of interleukin-10 in the cel transplantation group was significantly higher than that in the control group (P<0.05). Compared with the control group, the percentage of CD4+/CD8+, CD4+CD25high, CD4+CD25high Foxp3+and CD4+T cel s was significantly higher, and the percentage of CD8+T cel s was significantly lower in the cel transplantation group (P<0.05). Histopathological findings showed that there were a smal amount of infiltrated lymphocytes in the cel transplantation group with the presence of slight bleeding and edema, and these inflammatory reactions were milder than those in the control group. These findings indicate that bone marrow mesenchymal stem cel transplantation can effectively reduce the rejection in rats undergoing heart transplantation.

Objective To evaluate the clinical efficacy of endoscopic esophageal variceal ligation (EVL) for esophageal variceal bleeding (EVB) in elderly patients with hepatic cirrhosis.Methods From July 2007 to July 2013,clinical data of 198 patients who had been diagnosed with liver cirrhosis presenting with EVB were retrospectively analyzed.Among them,167 patients who had received EVL were divided into the elderly EVL group (n=97,age≥60 years) and the non-elderly EVL group (n=70,aged ＜ 60 years).The other 31 cases (aged ≥ 60 years) had received propranolol therapy.Treatment effectiveness,adverse effects,complications and the one-year survival rate of each group were analyzed.Results The efficacy rates and variceal recurrences were 77.3％ (75/97) and 78.6％ (55/70) in the elderly EVL group and 19.6％ (19/97) and 18.6％ (13/70) in the non-elderly EVL group,respectively,with no significant difference between the two groups (each P＞0.05).The re-bleeding rate was higher in the propranolol treatment group than in the elderly and non-elderly EVL groups [58.1％ (18/31) vs.24.7％ (24/97) vs,22.9％ (16/70),x2 =14.76,P =0.00].One-year survival rates in the elderly group,the non-elderly EVL group and the propranolol treatment group were 86.6 (84/97),88.6％ (62/70),64.5％ (20/31),respectively,with statistically significant differences between the three groups (x2 =10.24,P=0.01).Conclusions EVL is effective for the treatment of hepatic cirrhosis with EVB and can be used as a secondary prophylaxis measure for EVB in elderly patients with hepatic cirrhosis.

Social justice,as a part of the public policy and legal value,is an important target of the rule of law and should penetrate into all the activities in medical field.The doctor-patient relationship influences the realization of medical justice directly.This article analyses the status of the missing integrity between doctors and patients and the medical hazards it brings,from the perspective of the practice of doctor-patient relationship,and put forward the methods to construct the integrity of medical treatment.

OBJECTIVE:To summarize the key issues such as the drug waste and the phone calls affecting the working efficiency in pharmacy intravenous admixture service(PIVAS)and to put forward countermeasures so as to improve the working quality there.METHODS:The records about the drug waste in PIVAS and the phone calls that affected the working efficiency from clinical departments were analyzed statistically.RESULTS:Dispensing error and drug return were the main factors accountable for the drug waste in PIVAS.The proportion of phone calls from clinical departments demanding drug bills and drug dispensing was the highest,which greatly affected the working efficiency in PIVAS.CONCLUSIONS:The clinical staff should be informed not to make the unnecessary calls to PIVAS so as to improve the working quality in PIVAS.

Objective:To investigate the clinical efficacy of long-pulsed 1064nm laser combined with amorolfine hydrochloride in the treatment of patients with onychomycosis. Methods:Totally 106 cases of patients with onychomycosis were randomly divided into the observation group (n=53) and the control group(n=53) according to the random number table. The control group was given 5%amorolfine hydrochloride liniment, while the observation group was treated with long-pulsed 1064nm laser additionally. The course of treatment was 6 months. The clinical efficacy, length of deck in ward areas, length of deck in health zone, clearance of mycology and adverse reactions were compared between the groups. Results:The total effective rate of the observation group(90. 57%) was signifi-cantly higher than that of the control group(75. 47%, P<0. 05). After the treatment, the length of deck in ward areas in both groups were significantly decreased, while the length of deck in health zone were significantly increased (P<0. 05). The length of deck in ward areas in the observation group was significantly lower than that in the control group, while the length of deck in health zone was significantly higher than that in the control group(P<0. 05). The clearance rate of mycology in the observation group (86. 79%) was significantly higher than that in the control group (67. 92%, P<0. 05). There were no serious adverse reactions during the treatment course. Conclusion:Long-pulsed 1064nm laser combined with 5% amorolfine hydrochloride liniment in the treatment of patients with onychomycosis has remarkable, safe and reliable clinical effects, which shows important study value.
