[Summary] Graves'ophthalmopathy ( GO) is the most common extrathyroidal manifestation of Graves disease ( GD) . It is an organ-specific autoimmune disorder. The estimated incidence of GO in the general population is 16 women and 3 men per 100,000 population every year. Approximately 3%-5% of patients with GO are exposed to the potential of losing their sight and requiring optimized medical intervention. For the clinicians it is helpful to assess the degree of activity and severity of GO;both are important in deciding whether a patient requires intervention and which type of intervention is indicated. These interventions include management of hyperthyroidism, measures to relieve local symptoms, immunosuppressive therapies for active moderate and severe GO, and finally rehabilitative surgery for inactive patients.

Objective To construct the recombinant plasmid pYES6-S and express and purify spike protein of severe acute respiratory syndrome(SANS)coronavirus in Saccharomyces cerevisiae. Methods DNA fragments of SANS coronavirus were obtained by reverse transeription.Four over- lapped fragments of spike protein genes were amplified by polymerase chain reaction(PCR)and ligated into an integral spike protein gene by restriction enzyme digestion.The spike protein gene recombined with pYES6 and cloned into E.coll.The recombinant plasmid pYES6-S was induced and expressed in Saccharomyces cerevisiae(INVScl)by galactose.Results The recombinant plasmid pYES6-S was confirmed that inserted fragment was right in length,direction and base matching by restriction enzyme digestion and sequencing.The purified protein encoded by the whole spike protein gene was about Mr 110?10~3 identified by electrophoresis.Conclusion The whole spike protein gene of SARS coronavirus is cloned into E.coli and the protein is expressed in Saccharomyces cerevisiae successful ly.which can be helpful in SARS vaccine research.

Objective To study the effects of cluster nursing intervention on dysuria in hospitalized patients after renal biopsy. Methods A total of 106 hospitalized patients undergoing renal biopsy during April. 2016 to September. 2016 were divided into control group (50 cases) and experimental group (56 cases) by random number table method. The control group were implemented with traditional methods of care and the experimental group were implemented with cluster nursing intervention.The incidence of dysuria, first average urination time and post-operative urination pattern were compared between two groups. Results The incidence of dysuria in the experimental group was 10.7%(6/56), which was significantly lower than 28.0% (14/50) of the control group (χ2=5.156, P<0.05).The first average urination time of experimental group was (2.95±1.17) hours, which was lower than (5.04±2.27) hours of the control group (t =5.401, P<0.05). The proportion of patients with post-operative self-urination in the experimental group was significantly higher than that in the control group (χ2=6.152, P<0.05). Conclusions Cluster nursing intervention can reduce the incidence of dysuria, shorten the first average urination time, promote post-operative self-urination of patients after renel biopsy and enhance comfort.

Objective To investigate the influence of rehmannia glutinosa oligosaccharide(RGOs)on apoptosis of human adipose tissue-derived mesenchymal stromal cells(ADMSCs)induced by hydrogen peroxide(H2O2).Methods Cultured human ADMSCs were randomly divided into three groups as the normal group(group N,without any treatment),H2O2 group(group H,treated with 0.1 mmol/L H2O2),and RGOs group(group R,treated with 0.2g/L RGOs plus 0.1 mmol/L H2O2).After 1 h,6 h and 24 h,morphological changes of ADMSCs apoptotic were observed,the apoptotic rate was determined by flow cytometry.Results After 1 h,6 h and 24 h,the apoptotic rate of group H was significantly higher than that of the group N and group R(P<0.05),and the apoptotic rate of group H was significantly higher than that of the group R(P<0.05).Conclusion RGOs can attenuate apoptosis of human ADMSCs induced by H2O2.

OBJECTIVETo summarize and classify the frontal appearance of the philtrum in Nanjing' s young population, so as to assess the role of philtrum in the face aesthetics.

METHODSFrom August 2010 to December 2011, 160 Nanjing's youth, aged from 20 to 25 years old, underwent photographic study and measurement. The aesthetic rate was graded both for philtrum and the whole face. The results were statistically analyzed.

RESULTSThe standard philtral aesthetic appearance is a slim isosceles trapezoid, with an isosceles triangle whose obtuse angle is about 140 degrees reversed at the bottom, like a necktie. The aesthetic rating was highest for philtrum in male NO. 105 and female NO. 33, while for the whole face in male NO.45 and female NO. 7. The mean data of the major parameters were as follows: the length of mouth width was (50.0 +/- 4. 3) mm (male), (47.0 +/- 4.0) mm (female); the length of right red lip was (20.2 +/- 2.4) mm (male), (19.3 +/- 2.3) mm (female); the length of left red lip was (20.2 +/- 2.2) mm (male), (18.9 +/- 1.8 ) mm (female); the length of right philtrum column was (15.5 +/- 2.0) mm (male), (13.6 +/- 2. 2) mm (female); the length of left philtrum column was (15.6 +/- 1.9) mm (male), (13.7 +/- 2.3) mm (female); the length of philtrum sulcus was (17.3 +/- 2.1) mm (male), (15.3 +/- 2.4) mm (female). The upper breadth of philtrum was (5.6 +/- 0.8) mm (male), (5.5 +/- 1.1) mm (female); the middle breadth was (9. 5 +/- 1.1) mm (male), (8.5 +/- 1.2) mm (female); the lower breadth( cupid bow width) was (13.8 +/- 1.8) mm (male), (11.8 +/- 1.6) mm (female). The right half of cupid bow was (7.5 +/- 0.9) mm (male), (6.5 +/- 0.9) mm (female); The left half of cupid bow was (7.2 +/- 0.9) mm (male), (6.1 +/- 0.8) mm (female). The philtrum angle was (141.2 +/- 8.0) degrees (male), (141.3 +/- 6.1) degrees (female). Although there is slight difference in the measurement results between two sides of philtrum column and cupid bow (P < 0.01), it is not obvious by naked eyes. Except for the upper width of philtrum and the philtrum angle (P > 0.05), the other parameters have significant sexual differences (P < 0.05).

CONCLUSIONThe beautiful philtrum can not mainly decide the whole face aesthetics, which usually shows a harmony relationship between all the facial aesthetic units. The measurement results can be used as a reference for philtrum plasty.
