In the isolated adult rat's ventricular myocytes and artificial bio-membrane-liposomes, the lipid peroxidation caused by generating system of free radicals (FeCl2 & ascorbic acid ) was significantly inhibited by Co Q10, and the inhibition effect of Co Q10 was both dose-and time-dependent. The results showed that Co Q10 had an antioxi-dation effect and served as a scavenger of free radicals at the level of membrane .

Objective To investigate the diagnostic value of serum Cystatin C and 24 h urine microalbumin quantitative exami-nation in the early gestational diabetes kidney.Methods Chose 110 cases of patients from 37 to 40 weeks during pregnancy with gestational diabetes.According to the GFR,patients were divided into GFR moderate decline group A (30 ml/min/1.73m2 ≤GFR<60ml/min/1.73m2 ,n=30),GFR mild decline group B (60 ml/min/1.73m2 ≤GFR<89 ml/min/1.73m2 ,n=42)and GFR normal group C (GFR≥90 ml/min/1.73 m2 ,n=38).Choose the same gestational weeks 40 healthy preg-nants cases as control group D.Statistics of four groups of serum Cys C,24 h urine microalbumin quantitative,serum urea and creatinine,then analize.Results The levels of serum cystatin C and urine microalbumin compared between each group respectively,the differences were statistically significant (F=31.209,34.698,P <0.01,respectively).The levels of blood u-rea and creatinine in group A when compared with the other groups,found that the difference was statistically significant (F=5.845,4.575,P <0.01,respectively).When comparing the levels of blood urea and creatinine among the groups B,C and D,there was no statistical difference of significance (P >0.05).There was positive correlation between levels serum Cys C and urine microalbumin in group A and B (r=0.756,0.725,t=5.209,4.835,P <0.01,respectively).The sensitivity of Cys C and urine microalbumin were 95.2% and 90.5%,sensitivity of the combination of Cys C and urine microalbumin was 100% (χ2 =8.24,7.08,P <0.05,respectively).Conclusion As sensitive indicators of gestational diabetes in the early renal damage stage,joint detection of Cys C and urine microalbumin is of great significance for diagnosis and monitoring of diabe-tes in the early renal damage stage.

Objective:To discuss the clinical significance of structural chest zones for gynecomastia.Methods:A total of 687 gynecomastia patients, aged from 14 to 45 years old, with an average age of 27.0, were admitted to the Department of Plastic Surgery, Huashan Hospital Fudan University from January 2012 to December 2018. Simon classification was used to record. Conduct Simon classification according to the preoperative measurement of the chest. Surgical area design, photo analysis, breast ultrasound examination and Derriford appearance scale evaluation were conducted as well. Six zones can be divided as follows: zone 0 nipple-areola zone, zone 1 gynecomastia zone, zone 2 accessory-breast zone, zone 3 lateral-roll zone, zone 4 IMF(inframammary fold) zone, zone T relative-contraindication zone. Positive and lateral images of the chest were taken before and one week, one month, three months, six months, and 12 months after the operation, and the preoperative and postoperative changes of each structural zone were compared. At the follow-up of 12 months after the operation, patients’ satisfaction was counted.Results:687 patients, according to Simon classification, were divided toⅠ degreein 65 cases, Ⅱa degree in 257 cases, Ⅱb degreein 194 cases, Ⅲ degree in 171 cases. Before operation, except for Simon Ⅰ degree in 65 cases showed just raised to 0 zone, most of the rest of the patients contains 1 zone raised, 2-4 zones come in different patients. After liposuction and glandular stripping were performed in different zones, postoperative follow-up was conducted one week, one month, three months, six months, and 12 months after the operation. The dynamic observation was made of the change process of chest shape shaping during the follow-up, whether there were postoperative complications, poor local shape, or bad regional shape. Evaluation results of patient satisfaction 12 months after surgery: among the 687 patients, there were 634 patients with 10 points of satisfaction, and 53 patients with 8-9 points, including 48 patients of zone 0 and zone 1, three patients of zone 3, and 2 patients of zone 4.Conclusions:The structural chest zones of gynecomastia provides plastic surgeons and male patients with simple, intuitive, and highly recognized preoperative evaluation, which can provide appropriate, simplified, and accurate guidance for the selection of surgical methods.

Objective To observe the value of prenatal ultrasound measuring fetal cauda equina nerve parameters for diagnosing tethered cord syndrome(TCS).Methods Forty six fetuses with TCS(TCS group)and 591 healthy fetuses(control group)were retrospectively enrolled.The length,area and angle of cauda equina nerve were measured with prenatal ultrasound and compared between groups,and the value for diagnosing TCS was analyzed.Results Significant differences of the length,area and angle of fetal cauda equina nerve were found between groups(all P＜0.05),with the area under the curve for diagnosing TCS of 0.924,0.809 and 0.972,respectively.Conclusion Prenatal ultrasound measuring fetal cauda equina nerve parameters had high value for diagnosing TCS.
