Objective To correct the high supratarsal fold after cosmetic upper blepharoplasty is a challenge because of the shortage of both upper eyelid skin and fat.Levator shortening has been a procedure of choice selected by the surgeons to correct this condition.Methods Under local anesthesia, the desired crease was marked according to the characteristics of eyelid anatomy and aesthetic consideration for Asian women.The incision was made through the marked new skin crease and the old incision with surrounding scar tissue was incised.The adhesion between the skin and the levator aponeurosis was completely released.The levator aponeurosis was then divided above the tarsal plate.It could be shortened and then reattached to the tarsal plate depending on the amount of the upper eyelid skin and the degree of the ptosis.The skin incision was then closed to form new but lowered fold.Results Between 2003 to 2015, a total of 34 Chinese women underwent bilateral levator shortening for correction of high supratarsal fold after previous unsatisfactory upper blepharoplasty by other surgeons.There were no surgical complications postoperatively in this series and 32 patients (94.1%) were satisfactory for the outcome of the proper height of the supratarsal fold with at least 1 month follow-up.Only one patient (2.9%) required surgical revision for asymmetry of supratarsal folds and one patient (2.9%) for correction of deepened supratarsal fold.Conclusions The levator shortening can be an effective procedure to correct high supratarsal fold after unsatisfactory upper blepharoplasty in Asian women.It is especially useful to correct such a condition where there is shortage of the eyelid skin combined with the eyelid ptosis.
3.Clinical study of renal blood flow and endothelin in cirrhotic patients.
Chinese Journal of Hepatology 2004;12(5):278-280
OBJECTIVESTo find the relationship between hepatic dysfunction and renal blood flow (RBF).
METHODS49 patients with hepatic cirrhosis were studied via Color-Coded Duplex Ultrasonography detecting the pulsatile index (PI), resistive index (RI), peak systolic velocity (PS), peak diastolic velocity (PD) and peak systolic velocity/peak diastolic velocity (PS/PD) in the interlobar and arcuate arteries. The plasma endothelin (ET) levels were also evaluated.
RESULTSAccording to a modified Child's classification which assesses the severity of liver cirrhosis, we compared different groups and found that the worse the function of liver appeared coincidently with the higher PI and RI, especially RI (0.60+/-0.09, 0.66+/-0.06, 0.72+/-0.07, respectively, P < 0.01); The results also indicated that PI, RI increased obviously followed by the rise of ascites (PI: 1.14+/-0.20, 1.31+/-0.29, 1.42+/-0.36, respectively; RI: 0.61+/-0.09, 0.68+/-0.07, 0.77+/-0.05, respectively). The evaluation of plasma ET level demonstrated that its increment is intimately correlated with PI and RI.
CONCLUSIONIn patients with cirrhosis, RBF is directly correlated with the hepatic function. The correlation between ascites and RBF is also discovered. In patients who have liver cirrhosis, the plasma ET level obviously increased, indicating that ET probably is one of the active factors of renal vascular contraction.

Objective To analyze comprehensively the monitoring data of iodized salt in Zhangjiakou city during 2001 to 2009, and to provide basic information for working out control strategies of the iodine deficiency disorders. Methods According to the iodized salt monitoring requirements in National Iodine Deficiency Disorders Monitoring Program of Ministry of Health, a batch of nine salt samples were taken from each processing (wholesale)company of each county or district of the seventeen counties(districts) of Zhangjiakou once a month. Two townships (towns, street offices) were selected by their location of east, south, west and north in each county(district), and a township in central area each year. Four villages(neighborhoods) were selected in each township(town, street office),and eight household salt samples were collected in each village(neighborhood), and quantitatively determined by direct titration of iodine. Results Iodized salt processing(wholesale) : during 2001 to 2009, a total of 1728 batches was monitored, 1689 batch qualified, batch qualification rate 97.74%;15552 salt samples were tested, 15 357 qualified, iodized salt qualification rate 98.75 %. Household salt levels : 5297 villages (neighborhoods) of 1305 townships(towns, street offices) were monitored, 44 316 salt samples were collected, 43 274 qualified, iodized salt qualification rate 98.04%(43 274/44 141 ), iodized salt coverage rate 99.61%(44 141/44 316), qualified iodized salt consumption rate 97.65%(43 274/44 316). Rate of non-iodized salt was 0.40%(260/44 316), and salt median iodine was 30.02 mg/kg. Conclusions The iodized salt quality indicators are within the state-controlled range in Zhangjiakou city for nine years which remaines at relatively stable levels with a smaller range of annual fluctuations.Detection of non-iodized salt over the years has become the main factors affecting the effectiveness of the prevention and control measures.We should increase monitoring,supervision,and universal health education,and prevent the spread of non-iodized salt.

Objective To evaluate the electrocardiographic(ECG)-gated 4-dimensional computed tomographic angiography (4D-CTA) in the determination of pulsation of unruptured cerebral aneurysms (URCAs).Methods This study included 48 patients with 62 URCAs.Examinations of ECG gated 4D-CTA of dual-source CT were performed.Twenty sets of image data with the time intervals of 5% in a cardiac cycle were obtained after postprocessing on the workstation.The convex was defined as the point of pulsation if small bubble or small pointed convex could be found in continuous three or more images at the same location.The 62 URCAs were divided into two groups based on whether having a point of pulsation.All the URCAs were scanned at the follow-up by 3D-CTA or ECG gated 4D-CTA more than 120 days later.The diameters of aneurysms and aspect ratio between the two groups were compared with independent t test,while neck of aneurysms and follow-up time were compared with two-independent samples Mann-Whitney U test.The other variables including history of hypertension,type 2 diabetes,smoking et al between the two groups were analyzed by x2 test.The sensitivity and specificity of aspect ratio for diagnosis of pulsation were analyzed by receiver operating characteristic (ROC) curve.Results Pulsation was observed in 28 of the 62 URCAs.Aspect ratios in whose pulsation was or was not detected were 1.5±0.3 and 1.1±0.3,respectivelyThe difference between the two groups was statistically significant (t=-2.274,P<0.001).The sensitivity and specificity of the aspect ratio were 75.0% and 70.6%.After follow-up more than 3 months,of the 28 URCAs in which pulsation was observed,11 showed a change in shape,while in 34 URCAs without visible pulsation,5 showed a change in shape.The aneurysms with detectable pulsation were more likely to show a change in shape (x2=4.891,P=0.027),with an odds ratio of 3.753.Conclusions URCAs with a large aspect ratio are easily to show the pulsation by ECG gated 4D-CTA.Besides,the aneurysms with visible pulsation are more likely to show a change in shape after follow-up,which suggests a higher risk of rupture.

Macrophages are involved in many important biological processes and membrane proteins are the key effector molecules for their functions. However, membrane proteins are difficult to analyze by 2-DE based method because of their intrinsic tendency to self-aggregate during the first dimension separation (IEF). To circumvent the obstacle hampering membrane protein analysis, we combined one-dimensional SDS-PAGE with capillary liquid chromatography-tandem mass spectrometry (LC-MS/MS). Using this technique, we identified 458 GO annotated membrane proteins with extremely high confidence, including most known markers of peritoneal macrophages (e.g., CD11b, F4/80, CD14, CD18, CD86, CD44, CD16 and Toll-like receptor). Thirteen other CD antigens and 18 Ras-related small GTPase were also identified. In addition to those known macrophage membrane proteins, a significant number of novel proteins have also been identified. This research provides a valuable data set of macrophage membrane proteins, thus allowing for more comprehensive study of membrane proteins and a better understanding of the function mechanisms of macrophages in many biological processes.

OBJECTIVESTo investigate the clinical effect of sequential therapeutic intervention Yupei Qisun [compensating for weakness by invigorating Kidney (Shen) and Spleen (Pi) in advance] in Chinese medicine (CM) and hysteroscopic endometrial mechanical stimulation on the treatment of infertile patients with repeated implantation failure (RIF); and to study the differences in patients' endometrial thickness and type on the day of embryo transfer, serum hormone levels on embryo transfer day and clinical pregnancy outcomes.
METHODSIn the clinical study, 168 frozen-thawed embryo transfer (FET) cycles for couples with RIF conforming to the research protocol were randomly divided into three groups: a CM group with 56 cycles (CM combined with FET), a hysteroscopy group with 55 cycles (hysteroscopic endometrial mechanical stimulation), and a control group with 57 cycles (conventional FET). Differences in endometrial thickness on the embryo transfer day, levels of serum estradiol (E2) and progesterone (P) on the embryo transfer day, the E2/P ratio on the embryo transfer day, biochemical and clinical pregnancy rates, implantation rate, abnormal pregnancy rate and other indices were compared among the three groups.
RESULTSEndometrial thickness, E2 and P levels, and the E2/P ratio on embryo transfer day and other factors had no significant differences among groups. The biochemical pregnancy, clinical pregnancy, and implantation rates of the CM and hysteroscopy groups were significantly higher than the control group (P<0.05), and there were no significant differences between these two groups. The abnormal pregnancy rate had no significant difference among the three groups.
CONCLUSIONSSequential therapy of Yupei Qisun could significantly improve the clinical outcomes of rif-fet cycles, being equivalent to hysteroscopic endometrial mechanical stimulation, and provided a reliable method to treat such infertile couples.
