Embryonic stem cells(ESCs),a kind of totipotent cells,can differentiate into cell type of the 3 germ layers.Adult stem cells(ASCs) are pluripotent stem cells,which can self-renew and transdifferentiate into a completely different tissue derivative cells.Thus ASCs can transdifferentiate into germ cells in a certain condition.Great progress has made for the study on human ESCs.However,use of ESCs faces the immunological rejection,oncogenicity and ethical controversies problems,and these limit their uses for treatment of human diseases.On contrast,ASCs can advoid these problems,and they may have a better perspective.Germ cells as carriers of genetic materials,are worth of studying.If male germ cells can be derived from ASCs,this will open the possibilities for the use of these cells for male infertillty in clinical application.In this review,we will introduce the progress on derivation of male germ cells from ESCs and ASCs.

In this paper, we present a 3D virtual phantom design software, which was developed based on object-oriented programming methodology and dedicated to medical physics research. This software was named Magical Phan tom (MPhantom), which is composed of 3D visual builder module and virtual CT scanner. The users can conveniently construct any complex 3D phantom, and then export the phantom as DICOM 3.0 CT images. MPhantom is a user-friendly and powerful software for 3D phantom configuration, and has passed the real scene's application test. MPhantom will accelerate the Monte Carlo simulation for dose calculation in radiation therapy and X ray imaging reconstruction algorithm research.

Celastrol is a type of quinone methyl triterpene isolated from traditional Chinese medicine Tripterygium wilfordii, with pharmacological activities, like anti-inflammatory, immunosuppression and anti-tumor. This study focused on the effects of celastrol on adhesion, migration and invasion of lung cancer cells. The migration inhibition of lung cancer cells induced by celastrol was detected by the scratch test. The invasion inhibition of lung cancer cells induced by celastrol was measured by the transwell experiment. RT-PCR and Western blot were used to determine the effect of different concentrations of celastrol in integrin family and Akt signaling pathway in lung cancer cells. The results showed that celastrol inhibited adhesion, migration and invasion of lung cancer cells and expressions of integrins β3, β4, αv and phosphorylated Akt, GSK-3β, c-Raf, PDK1 in Akt signal pathway in a dose-dependent manner. Therefore, the study implies that Celastrol could inhibit the metastasis of lung cancer cells by suppressing Akt signaling pathway and expression of integrins.

Objective To discuss the effect of health education to family members of patients with chronic heart failure. Methods 150 patients with family members as accompanies were divided into the observation group and the control group with 75 patients in each group. Health education was given to patients as well as their family members in the observation group, while health education was given only to the patients in the control group. The mastering of disease-related knowledge by family members of the observation group was observed after 15 days. The rehospitalization of the two groups by telephone follow-up was carried out six months after discharge. Results The mastering of disease-related knowledge by family members of the observation group was better compared with before health education. The rehospitalization rate of the observation group was 13.3%, which was lower than 44.0% of the control group. Conclusions Health education to family members of patients with chronic heart failure can increase treatment effect of patients, decrease disease relapse and lower rehospitalization rate.

Objective To compare the effects of different doses of dexmedetomidine on postoperative analgesia and sedation.Methods From January 2014 to November 2015,60 cases who needed postoperative analgesia and sedation in our hospital were selected.According to the dosage of dexmedetomidine,they were divided into control group and observation group,30 cases in each group.Two groups of patients were given analgesia pump for analgesia, with 0.5μg·kg-1·h-1,1.0μg·kg-1·h-1 two doses of dexmedetomidine,and analgesia 48 h.At different time points,the VAS pain score,Ramsay sedation score of the two groups were compared,the calm satisfaction in both two groups was recorded,the average incidence of delirium and delirium score in the process of the treatment and the occurrence of adverse reactions were observed.Results With the extension of time of postoperative analgesia,VAS scores in each group decreased,VAS scores in the observation group after 4h,8h,12h were (3.01 ±0.53)points, (1.95 ±0.58)points,(1.52 ±0.35)points,which were lower than those of the control group[(3.92 ±0.32)points, (2.86 ±0.67)points,(2.25 ±0.78)points],the differences were statistically significant (t=3.42,4.11,2.43,all P<0.05).After 24h,48 h,VAS score between the two groups had no significant difference(P>0.05).Postoperative 4h Ramsay score between the two groups had no significant difference (P >0.05 ).With increased postoperative analgesia time,Ramsay scores in two groups decreased,postoperative 8h,12h,Ramsay scores in the observation group [(2.95 ±0.83)points,(2.22 ±0.55)points]were lower than the control group[(3.76 ±0.78)points,(2.98 ± 0.89)points,t=3.45,2.38,all P<0.05].Postoperative 24h,48 h,the Ramsay scores between the two groups had no significant difference(P>0.05).The sedation satisfaction of the observation group (96.67%)was higher than the control group (86.67%),the incidence rate of delirium and delirium average score [3.33%,(15.11 ± 2.03)points]were lower than the control group[13.33%,(19.23 ±2.21 )points],the differences were significant between the two groups (t =4.32,4.32,3.27,all P<0.05 ).After treatment,the adverse reactions were mainly bradycardia,nausea,vomiting,drowsiness,respiratory depression,urinary retention.The overall incidence rate of adverse reactions between the two groups had no significant difference (P >0.05 ).Conclusion The effect of 1 .0μg·kg-1 · h-1 concentration dexmedetomidine within 24h of postoperative analgesia sedative is best,it can reduce the incidence of postoperative delirium,and without obvious drug side effects.

Objective To investigate the incidence of xerostomia in patients with acquired immune deficiency syndromes (AIDS), clarify the association between AIDS and xerostomia to promote AIDS patients' oral health. Method The oral health conditions of 200 hospitalized AIDS patients were investigated by a self-designed evaluation form. Results Among 200 patients, xerostomia occurred in 113 (56.6%) . Among the xerostomia patients, 32.7% were without brushing habits, 63.7% with long-term medication and 43.1% (31 cases) with mainly antibiotics, antivirals and antifungal drugs. 30 (31.9%) patients with xerostomia were mainly associated with symptoms of oral burning, lips dry and scaly, periodontitis, oral mucosal dryness and tooth loss. Conclusions AIDS could increase the incidence of xerostomia. Some effective measures should be taken to promote patients' oral health, including improving AIDS patients' awareness of oral health, close observation of adverse reactions after treatment,looking for related causes, timely and targeted therapies,early detection and treatment of associated symptoms.

Objective:To Study the efficacy and satety of lamivudine in the treatment of CHB and HBV carrier.　Methods:All patients were divided into three groups. 21 patients with CHB were classified CHB test group(namely groupⅠ), 16 HBV carries were classified ASC test group(namely Group Ⅱ), 40 patients with CHB were CHB controlled group(namely controlled group). Both group Ⅰ and group Ⅱ received lamivudine, group Ⅰ was added protecting liver therapy. The controlled group only received protecting liver therapy. The treatment courses of three groups were one year. 　Results:The effective rates of group Ⅰ and group Ⅱ were higher than the controlled group in turning into negative HBeAg and HBV-DNA, both the negative-turning rate of liver functions and hepatic serology target declining fibrosis in group Ⅰ was more significant than the controlled group without severe side effect. 　Conclusion:Lamivudin is efficient and safe medicine in the treatment of CHB and HBV carrier.
