The influence of storage time and temperature of rat's blood and liver on cyanide concentration is reported in this paper. It was investigated when the blood and liver were kept in temperature 4℃ for 168h. There was little change in cyanide concentration. When they were kept in temperature 200170, the concentration of cyanide was increasing as the duration was prolonged. The cyatiide concentration in liver was 1. 17 times higher at 168th hour than at 4th hour.

[Summary] Gastric cancer is seriously dangerous to human health with constantly high incidence .Human gastric mucosa can express gastrokines that can inhibit cancer cell growth .Gastrokines is expressed abundantly in normal tissues while downregulated or absent in gastric cancer and precancerous lesion .It plays an important role in the suppression of gastric cancer proliferation combining with the other factors such as helicobacter pylori infection or trefoil factors .In this paper we made a review about the suppression of gastrokines on gastric cancer cell proliferation .

Objective:To study the difference of upper airway form and hyoid position of the adults with different vertical facial types.Methods:Cephalograms of 120 adults with different vertical facial types were retrospectively investigated by computerized cephalometric analysis.Upper airway depths and hyoid position were measured,and differences were compared between male and female,also compared among different vertical facial type groups.Results:The sagittal depth of upper airway in male was larger than that in female,but there was no statistical difference except V-LPW.Among different vertical facial types,the sagittal depths of upper airway in high angle group was smaller than that in average angle group and low angle group.There was statistical difference in hyoid position between genders,AH-SN,AH-FH and AH-C3 in male were larger than in female(P

The purpose of this review is to help people having a right attitude toward the health effects of expo-sure to extremely low frequency (ELF) electromagnetic fields. In this paper, epidemiological studies and animal studies in vivo were reviewed in order to evaluate the health impacts of exposure to ELF electromagnetic fields. The results show that the association between ELF electromagnetic fields and the risk of tumors as well as non-tumor health effects is very weak even uncertain.

Orthopedic implants are widely applied and achieved favorable effects.However,the safety,efficacy and other ethics problems exist because the implants will stay in body for a long period of time.In addition,patients have different extent of functional impairment,and self-care ability reduction even loss when they are admitted to the hospital,so their mental condition needs great attention.This paper summarized and discussed mental and ethical problems between doctors and patients during diagnosis and treatment so as to provide self-control for future treatment.

Objective To investigate the diagnostic value of the early slope value of enhancement in differentiating benign from malignant musculoskeletal masses.Methods Dynamic contrast-enhanced gradient-recalled acquisition in the steady state imaging(GRASS) was performed to evaluate 36 musculoskeletal masses(18 malignant,18 benign).The difference of the early slope value of enhancement was analysed and compared between benign lesions and malignant ones.Using ROC curve plotting obtained the best decisive threshold.Spearman rank correlation analysis was used to determine the relation between slope and microvessel density of tumor tissues.Results The average early slope value of enhancement was (4.33?2.70)% per second (range 0.97%～10.50% per second)for malignant lesions,and was (1.46?0.97)% per second(range 0.37%～3.86% per second)for benign ones.There was an apparent statistical significance between benign and malignant tumors(?

Objective To observe and evaluate the clinical effect of Dentium planting system by once procedure.Methods A total of 45 patients who had 55 Dentium implants implanted were followed up for one year. Permanent restorations were finished 12 weeks after once procedure.Clinical effects were evaluated through clinical and imaging examination.Results Through the 55 Dentium implants of 45 patients,the success rate was 100%.All patients were satisfied with aesthetics and occlusal function.Conclusion Dentium implant completed by once procedure is safe and reliable with once procedure on clinical application.Both the survival rate and successful rate of implants were 100%.High degree of satisfaction from patients was achieved.Both bone tissue and soft tissue are well preserved.This system can obviously reduce bone resorption and improve aesthetic effect.
