Objective To observe the influence of technetium [99Tc] methylenedipho-honate (99Tc-MDP) on osteoclastogenesis induced by receptor activator of NF-κB ligand (RANKL) and macrophage-colony stimulating factor (M-CSF)in peripheral blood mononuclear cells in patients with rheumatoid arthritis, and to study the mechanism of 99Tc-MDP in osteoclast differentiation. Methods The monocytes/macrophages were isolated from peripheral blood in patients with rheumatoid arthri-tis, incubated in RPMI-1640 with receptor activator of NF-κB ligand (RANKL, 25 μg/L), macro-phage-colony stimulating factor (M-CSF, 25μg/L ) and different concentrations of 99Tc-MDP (5, 10, 20,and 50 mg/L) for 4,12, and 20 days. Tartrate resistant acid phosphatase staining was used to observe the formation of osteoclasts. Results After 12 or 16 days culture of peripheral blood mononuclear cells, plenty of large nultinuclear cells could be found on the coverslips. 99Tc-MDP markedly inhibited those changes and the inhibitory effects were increased as the concentration of 99Tc-MDP increased (P<0.05). Conclusion 99Tc-MDP probably has some protective effect on rheumatoid arthritis by inhibiting osteoclast formation.

AIM: To evaluate the efficacy of simvastatin on exercise-induced myocardial ischemia in patients with stable exertional angina pectoris and hypercholesterolemia. METHODS: Ninety patients with stable exertional angina pectoris, positive rate of exercise test and hypercholesterolemia were randomly divided into two groups: the therapy group assigned to a 12-week treatment period either diet plus simvastatin (n=45); the control group with diet alone (n=45). All the patients underwent exercise testing before and after the treatment period. RESULTS: (1) Simvastatin-treated patients had a significant variation in total cholesterol, triglyccrides, high-density lipoprotein cholesterol and low-density lipoprotein cholesterol after treatment (P

Activated leukocyte cell adhesion(ALCAM),also known as CD166/MEMD,is a transmembrane glycoprotein,which belongs to one of the members of the immunoglobulin superfamily and is one of cell adhesion molecules.In vivo,ALCAM is divided into three subtypes including membrane ALCAM,cytoplasmic ALCAM and soluble ALCAM,which mediate a variety of pathophysiological processes involved in the body by regulating cell-to-cell tropism or heterophonic adhesion.The abnormal expression of ALCAM is closely related to the invasion and metastasis of various tumor cells,and has a certain effect on the sensitivity of radiotherapy and chemotherapy.The article reviews the latest advances in ALCAM of gynecological malignancies.

Hospital-acquired conditions (HACs)are key to patient safety.This paper introduced a new classification system of HACs,the CHADx model,and described the principle and method of establishing the model as well as the problems found during its use.The model can provide a basis for studying the problem of incidence,causes and influence factors of hospital acquired conditions,so as to help medical institutions to explore the causes of HACs and to ensure patient safety and improve the quality of health care.

Objective To compare the fetal and maternal outcomes of labor undergoing epidural block anesthesia with and without using hand-and-knee position in the second stage of labor.Methods A total of 1,158 subjects were included in the study.There were 560 subjects in the study group and 598 cases in the control group.All the subjects were divided into study and control group according to the randomized numbers.Both groups underwent epidural block anesthesia and used the same labor way in stage I and stage 3.In the study group,the hand-and-knee position was used for 15～30 minutes combined with uterine contractions and the delivery was done in the lithotomy position.In the control group,the gradidea took the semi-recumbent position with bent knees and bed elevated 40°,combined with uterine contractions until the delivery was done in the lithotomy position.The labor time of stage1,stage2,stage3 and all abor,labor way,perinaueum,complications and newborns were compared.Results The average time of the second stage labor and all labor in the observation group were significantly shorter than those of the control group (P＜0.05).The labor ways in the observation group was better than that of the control group (P＜0.05).The incidence of postpartum urinary retention in the observation group was significantly lower than that of the control group (P＜0.05).The differences of labor time for stage 1,stage2,perinaueum,blood loss rate,newboms' s tomor and neonatal asphyxia between two groups were not statistically significant (P＞0.05).Conclusions Under continuous epidural block anesthesia,the use of the hands-and-knees position in the second stage of labor can reduce the incidence of operative delivery,shorten the labor process,and reduce maternal complications.The method is worthy of promotion.

OBJECTIVE:To observe clinical efficacy and safety of Ebastine tablet combined with Chushi zhiyang ointment in the treatment of hand keratinizing chapped eczema. METHODS:135 cases of hand keratinizing chapped eczema were divided into control group A(45 cases),control group B(43 cases)and treatment group(47 cases)according to treatment regimen. Control group A was orally given Ebastine tablet,10 mg each time,qd;control group B was given Chushi zhiyang ointment alone,twice a day,morning and evening,applying thin layer of ointment on the affected area;treatment group was given same dose of Ebastine tablet orally and applied Chushi zhiyang ointment on the affected area. 3 groups received treatment for consecutive 4 weeks. Clinical efficacies of 3 groups were observed as well as the scores of pruritus,skin lesion area,keratinization,rhagades and VAS before and after treatment. The occurrence of ADR was compared among 3 groups. RESULTS:The total effective rate of treatment group was 68.09%,which was significantly higher than that of group A(42.22%)and control group B(16.28%),with statistical significance(P<0.05). There was no statistical significance in the scores of pruritus,skin lesion area,keratinization,rhagades and VAS among 3 groups before treatment(P>0.05). After treatment,above scores of 3 groups decreased significantly,and those of treatment group were significant-ly lower than those of control group A and B,with statistical significance(P<0.05). There was no statistical significance in the inci-dence of ADR among 3 groups(P>0.05). CONCLUSIONS:Ebastine tablet combined with Chushi zhiyang ointment is effective for hand keratinizing chapped eczema,and can significantly improve the skin of patients with good safety.

Objective To investigate the role of nurses in civil cardiac death organ donation work.Methods Cooperating,propagating and promoting in civil cardiac death organ donation; building a bridge between the families of organ donation,donor coordinators,physicians and hospital ethics committees; participating in organ donation medical ethics assessment work; cooperating with the doctors do intend to maintain organ donation,access and preservation; protecting donors remains.Results During the time of July 2011 to November 2013,we successfully completed 52 cases of civil cardiac death organ donation cooperating with doctors,and got 41 liver,which entered the national organ allocation system for distribution.Conclusions The nurses will play a more and more important role in work of civil cardiac death organ donation cooperating with doctors.
