Objective To evaluate the Cys-C、β~2-MG、RBP as marker三of early diagnosis in patients with diabetic nephropathy Ⅱ(DN).Methods ninety patients with DN were divided into three groups according to urinary albumin excretion rate (UAER),that is normal,micro and mass group.Serum Cys-C、β~2-MG、RBP、BUN,Crea were detected and parallelly contrasted in the three groups and control group with thirty healthy people.Results compared with the control group,the serum Cys-C、β~2-MG、RBP of micro and mass group both significantly increased and the normal group had no significant difference.The positive rate of Cys-C、β~2-MG,RBP in mass group was respectively 100%、100%、96.1%;the positive rate in micro group as follows:Cys C (92.3%)＞B2-MG(84.6%)＞RBP(66.6%)＞Crea(46.1%)＞BUN(28.2%).Conclusion serum Cys-C、β~2-MG、RBP have high positive rates in patients with diabetic nephropathy Ⅱ(DN).They can be used as early diagnostic marker of diabetic nephropathy Ⅱespecially Cys-C.

BACKGROUND: Vitapex is an injectable root canal filling material. It possesses effects of antibiosis, analgesia, as well as promotes formation of alveolar bone, dentin and cementum, which had been widely used in apexification. However, it also has weakness of long induction time and need reduplicated subsequent visit.OBJECTIVE: To explore the therapeutic effect of mineral trioxide aggregate (MTA) and Vitapex paste on apexification.DESIGN, TIME AND SETTING: The contrast observation experiment was performed at the Department of Stomatology,Shenyang Children's Hospital from February 2006 to November 2008.PARTICIPANTS: A total of 42 patients with 49 teeth were included in this study, including 28 anterior maxilla and 21 premolars.The X-ray film showed that the root tip of teeth was immature.METHODS: The teeth were randomly divided into the experimental group (n=25) and control group (n=24), which was apexificated by MTA and Vitapex paste, respectively.MAIN OUTCOME MEASURES: The effective rate of two groups was compared at months 3, 6 and 12 after operation.RESULTS: All teeth were included in the final analysis. The effective rate of experimental group was greater than the control group at 3 months after operation, and the difference had significant (P < 0.05), while, the effective rate was similar in two groups at 6 and 12 months after operation (P > 0.05).CONCLUSION: Both MTA and Vitapex paste are ideal filling materials in apexfication. Nevertheless, MTA may be a substitute in apexfication for its short therapy duration and precisely therapeutic effect.

Objective To investigate whether there is a thinning of the retinal nerve fiber layer (RNFL) in the eyes of diabetic patients and to analyze the relationship between RNFL thickness and several diabetic risk factors. Methods Forty-two type 2 diabetes mellitus patients aged 47-70 years were enrolled in this study. All the subjects underwent ophthalmologic examinations and glaucoma diagnosis (GDx) nerve fiber analyzer scanning with two different modes: variable cornea compensation (VCC) and enhanced cornea compensation(ECC).The GDx parameters included the temporal-superior-nasal-inferior-temporal average (TSNITave), superior and inferior averages, the TSNIT standard deviation and the nerve fiber indicator (NFI). The receiver operating characteristic (ROC) was applied to study the diagnostic ability of indices. The association between risk factors and the NFI was studied. Results The area under the curve for the ROC of the NFI was the largest for both the ECC and VCC modes. There was a significant relationship between age and RNFL thinning. However, there was no significant association between diabetic duration and fasting blood glucose with RNFL thinning. The influence of age on NFI was greater in diabetic patients than in control subjects. Conclusions Age has an important influence on the NFI of diabetic patients. Diabetic patients with normal ocular fundus may have RNFL thinning.

Objective To evaluate the association of age and retinal nerve fiber layer (RNFL) thickness by means of scanning laser polarimetry in a sample of healthy Chinese eyes. Methods One hundred and fifty eyes of 150 healthy subjects underwent RNFL scan in two different modes (Variable Cornea Compensation,VCC;Enhanced Cornea Compensation,ECC) of Glaucoma Diagnosis Variable Cornea Compensation Nerve Fiber Analyzer.The parameters included temporal-superior-nasal-inferior-temporal (TSNIT) average,superior average,inferior average,TSNIT standard deviation,and nerve fiber indicator (NFI). Results Mean values of TSNIT average,superior average,inferior average,TSNIT standard deviation and NFI in VCC mode were (57.12±6.26),(69.35±4.21),(67.59±7.06),(25.46±4.02),(17.35±7.59),while the parameters' values in ECC mode were (56.15±5.32),(68.24±6.63),(66.90±2.40),(24.80±6.76),(18.84±8.51),respectively.The differences between the values of VCC and ECC modes were not statistically significant.The parameters' values of total subjects were associated with age.But there were no significant associations between age and parameter values in the eyes of those older than 40 years old subjects. Conclusions There are no significant differences between the RNFL values detected by VCC and ECC modes in 150 healthy Chinese eyes.Age has influence on RNFL thinning in 21-70 years old healthy eyes,but not in the eyes of older than 40 years old people.

Objective] To explore the clinical experience of Ma Weiming in the treatment of insomnia.[Method] By following the teacher clinic, the author summarizes chief physician Ma Weiming’s academic experience of treatment of insomnia with classical prescriptions. [Results] In Ma Weiming's opinion, everything harasses the heart, mind vacillation, inducing liver ’s function of storing soul abnormal, the spirit restless is due to insomnia with much dream. So teacher Ma pays attention to “dream diagnosis”.The treatment of insomnia must be combined with heart and liver, making the mind quiet and the liver comfortable. He likes using flowers to balance Qi. In Ma Weiming's opinion, collaterals are invaded by prolonged illness, due to blood stasis. The treatment should use insect drugs to dispell wind and remove obstruction in the meridians, purifying orifices, promoting sleep. [Conclusion] According to the etiology of insomnia to distinguish among different dreams, teacher Ma uses classical prescriptions and combines with his own unique clinical experience on treating insomnia, which has significant effect and worth generalizing.

Soluble ST2 (sST2) is a decoy receptor of IL-33 in blood.sST2and ST2L (receptor on cell membrane) seem to be markedly induced in mechanically overloaded cardiac myocytes,especially the expression of sST2.A large number of sST2 bind IL-33 thus subtracting IL-33 from the interaction with ST2L,potentially attenuating the cardioprotective effects of IL-33/ST2L pathway.Recently,sST2 has emerged as a novel for heart failure biomarker.Though sST2 was a less robust marker for the diagnosis of heart failure than NT-proBNP,it has been implicated in the prognostication of patients with acute dyspnea,acute or chronic heart failure and myocardial infarction,with particular value for mid-and long-term prognosis.However,further studies are needed in order to better point out the evidence for a routine use of sST2 evaluation in patients suffering from cardiovascular diseases.

Objective To assess the influence of full-thickness continuous suture method and layer interrupted suture method in emergency abdominal operation closure.Methods Two hundred and thirtyseven patients of emergency abdominal operation were divided into full-thickness continuous suture method group (145 cases) and layer interrupted suture method group (92 cases) according to the suture method.The rate of incision liquefaction and infection,time of incision suture were compared between the 2 groups,the patients with incision liquefaction and infection were given bacterial culture.Results The time of incision suture in full-thickness continuous suture method group was significantly shorter than that in layer interrupted suture method group [(18.37 ± 7.42) min vs.(25.92 ± 5.79) min],there was statistical difference (P ＜0.01).There were no statistical differences in the rate of incision liquefaction and infection,the rate of incision primary healing between the 2 groups (P ＞ 0.05).In full-thickness continuous suture method group,the rate of incision liquefaction and infection in median incision was significantly lower than that in rectus abdominis incision [18.58％ (21/113) vs.31.25％ (10/32)],the rate of incision primary healing was significantly higher than that in rectus abdominis incision [81.42％ (92/113) vs.68.75％ (22/32)],there were statistical differences (P ＜ 0.05).In layer interrupted suture method group,there were no statistical differences in the rate of incision liquefaction and infection,the rate of incision primary healing between median incision and rectus abdominis incision [33.33％ (23/69) vs.26.09％(6/23),66.67％ (46/69) vs.73.91％ (17/23),P ＞ 0.05].The rate of incision liquefaction and infection in median incision of full-thickness continuous suture method group was significantly lower than that in median incision of layer interrupted suture method group,and the rate of incision primary healing was significantly higher than that in median incision of layer interrupted suture method group,there were statistical differences (P ＜ 0.05).There were no statistical differences in the rate of incision liquefaction and infection,the rate of incision primary healing in rectus abdominis incision between the 2 groups (P ＞ 0.05).The bacterial culture result in patients with incision liquefaction and infection showed positive was in 26 cases,in full-thickness continuous suture method group was in 10 cases (6.90％,10/145),in layer interrupted suture method group was in 16 cases (17.39％,16/92),there was statistical difference (P ＜0.05).The mostly bacterial of infection was Escherichia coli.Conclusions The full-thickness continuous suture in median incision can shorten operative time and reduce the rate of incision liquefaction and infection in emergency abdominal operation.Suture technique has important impact on incision healing.

Objective] To discuss the inner experiences of occupational injury of laboratory animal workers, and provide basis for conducting targeted occupational protective education and health management. [Methods] The phenomenological methodology was used in the study. 12 laboratory animal workers were participated in non-structured interview regarding the experiences of occupational injury. [Results] 3 themes were found including:category of occupational injury(physical injury, chemical injury, biological injury); emotional experiences of occupational injury(fears and concerns, helplessness and self-abasement); help most needed(more attention, knowledge supports, advanced and convenient protective equipment and hardware facilities). [Conclusion] Management of experimental animal industry should lay great emphasis on occupational health and protection of laboratory animal workers, increase both financial and material resources, and enhance occupational protection education, in order to maximize bad physical and psychological effects from occupational injury.

Objective To explore the features of gallbladder adenomyoma in sonogram, and improve the abilities of diagnosis and differential diagnosis. Method Sonograms of 8 patients with proven gallbladder adenomyoma were retrospectively analyzed and correlated with pathologic findings. Results Eight patients had sonographic evidence of localized intramural nodular,which were round-like and hypoechoic,with anechoic space and tiny bright echos, confined almost exclusively to the fundus of gallbladder. Five patients were also evident with associated gallstones and chronic cholecytitis. Conclusion Sonograms of gallbladder adenomyoma have marked features, which can be differentially diagnosed from other projective lesions of gallbladder.
