Objective To investigate the influence of different excipients on the stability of baicalin solution.Methods The thermostatic accelerated test was used to observe the effect of solubilizing agent (Meglumine and Glucose), solubilizer (Pluronic F- 68) and stabilizer (HP- ? - CD) on baicalin stability and the concentration of baicalin was determined by HPLC. Results The valid period of baicalin solution with solubilizing agent added was shortened, and that with solubilizer and stabilizer added prolonged. Conclusion It is feasible to increase the stability of baicalin solution with Pluronic F- 68 or HP- ? - CD added. 

Objective To explore the application effect of epidural labor analgesia for primipara.Methods 176 labor primipara were divided into observation group and control group by digital table.The control group was given non-drug labor analgesia,the observation group was given epidural labor analgesia.The analgesic effects of the two groups of childbirth way were recorded.Results After the intervention,in the observation group,the anxiety self-assessment rating scale,depression self rating scale score were (42.65 ±1.87)points,(45.76 ±3.05)points, which in the control group were (46.34 ±3.88)points,(51.93 ±4.95)points,there were statistically significant differences between the two groups(t=8.036,9.954,all P<0.05).In the observation group,the activematernal plasma cortisol,the first stages of VAS score,the second labor VAS score,the third labor VAS score were (31.06 ± 3.67)nmol/L,(1.88 ±0.45)points,(3.54 ±1.32)points,(2.43 ±1.19)points,which in the control group were (38.76 ±5.22)nmol/L,(2.78 ±0.96)points,(4.86 ±3.15)points,(3.85 ±2.21)points,there were statistically significant differences between the two groups(t=11.319,7.963,3.625,7.963,all P<0.05).In the observation group,the maternal postpartum haemorrhage amount,episiotomy rate,neonatal asphyxia rate were (186.71 ± 32.18)mL,14.78%,1.14%,which in the control group were (254.82 ±45.96)mL,35.23%,7.95%,there were statistically significant differences between the two groups(t=11.387,χ2 =9.818,4.714,all P<0.05).Conclusion Epidural labor analgesia application in primipara can reduce maternal negative psychological stress,relieve labor pain degree,reduce episiotomy rate and postpartum hemorrhage occurs,improve and outcomes and improve maternal and child safety,it is worth popularization and application in clinic.

AlM:To compare the functional and cosmetic effects of two different surgical techniques for congenital ptosis.
METHODS: The patients were divided into four groups according to the operation method: Patients undertook bilateral fascial suspension surgery as Group A ( 42 eyes of 21 cases ); Patients undertook bilateral levator muscle shortening surgery as Group B ( 38 eyes of 19 cases );Patients undertook unilateral fascial suspension surgery as Group C ( 24 eyes of 24 cases ); Patients undertook unilateral levator muscle shortening surgery as Group D (29 eyes of 29 cases). Each group patients were followed for postoperative function and appearance effect.
RESULTS: 1 ) Early postoperative of two operation function success rate was up to 100%, the function of levator muscle shortening surgery was 97. 01% in the late postoperative, was higher than bilateral fascial suspension surgery (87. 88%), with statistical difference in both surgerys (P<0. 05). 2) Appearance effect of two kinds of operation method in early postoperative had no statistical difference (P >0. 05); ln the late postoperative, the mean grades for “Lid Contour” and “Lid Crease” of Group B were better than that of Group A (P<0. 01). While the mean grades for “Lid Contour”, “Symmetry of Lid Height” and “Lid Crease” of Group D were similarly better than that of Group C (P<0. 01).
CONCLUSlON: Two kinds of operation method have good effects on the treatment of congenital ptosis. ln terms of cosmetic effect, levator muscle shortening surgery is better.

Objective To investigate the potential role of FoxP3-expressing CD4+CD25+ regulatory T cells in children with asthma.Met-hods Intracellular 3-colour flow cytometry and real time PCR were used to assess the expression of FoxP3 in peripheral blood mononuclear cell(PBMC)of asthma,repectively.Results There were similar frequencies of CD4+ CD25+ T cells in peripheral blood of asthma patients and healthy subjects.However,the percentage of CD4+CD25high and CD4+CD25+FoxP3+ in asthma group were lower than those in healthy subjects(Pa

Background The pathogenesis of pterygium has been in the study.Relative molecular biology study showed that pterygium is a tumor-like lesion,and based on overseas literatures,human papillomavirus (HPV) is positively expressed in 100％ patients with pterygium in some region.However,if this result is suitable for Chinese patients is unclear.Objective This study was to identify the role of human HPV in the pathogenesis of pterygia in Wuxi area.Methods Forty-eight pterygium specimens including 7 recurrent pterygia and 41 primary pterygia were collected during the operation,and these patients were from Wuxi area.Two cervical carcinoma specimens and 2 conjunctiva specimens from normal donors were obtained as positive control and negative control respectively.The fluorescent quantitative polymerase chain reaction (FQ-PCR) was used to detect HPV DNA of specimens.Results The amplified curves of HPV 6,11 of pterygium specimens,cervical carcinoma specimens and normal specimens were all below the positive quality control curve,but the amplified curves of HPV16,18 were above the quality control curve in cervical carcinoma specimens; while those of pterygium specimens and normal conjunctival specimens were all below the quality control curve.HPV16/18 was identified in 2 cervical carcinoma specimens,but no HPV6/11 was detected in 2 cervical carcinoma specimens.However,HPV DNA expression in primary and recurrent pterygias were absent.Conclusions According to these results,HPV is not the primary cause for the pathogenesis of pterygium in Wuxi region.

Objective To explore the clinical value of real-time three-dimensional echocardiography (RT-3DE) in percutaneous transcatheter closure treatment of atrial septal defect (ASD). Methods The sizes,shapes and sites of ASD were visualized by RT-3DE and measured by full volume rendered three-dimensional echocardiography (3DE) before operation and after closure operation in 11 ASD patients,and compared with those from two-dimensional echocardiography(2DE) and the operation. Results Before the operation,RT-3DE visualization showed that the secundum ASD′s sites of the 11 patients were central and shapes were mostly ellipse. In this study a significant difference was found in the measurements of long distances of ASD between 3DE and 2DE [( 28.9 ? 8.2 )mm vs ( 20.0 ? 7.3 )mm,P 0.05 ]. Maximal diameters of defects measured by 2DE[( 21.1 ? 3.5 )mm,P

Objective To study the velocity pattern of ischemic myocardium change during systolic phase by Doppler tissue imaging(DTI). Methods Twenty-three dogs were investigated as two groups. In 13 open-chest dogs as group A, regional wall motion abnormalities were induced by occluding branches of left circumflex coronary arteries(LCX). Left ventricular(LV) wall systolic velocity patterns at the mid-wall portion of the middle of LV posterior walls in the short-axis direction were recorded with DTI before and after artery occlusion. Ten dogs as group B were operated to occlude branches of LCX. Before and one week after operation the same parameters were recorded by transthoracic method. Results There were positive velocity peak(IVC 1), negative velocity peak(IVC 2) during isovolumic contraction and positive velocity peak(S) during ejection in DTI spectra of all normal LV posterior walls. The peak velocities of IVC 1 and S decreased significantly, but the peak velocity of IVC 2 increased significantly after occluding branches of LCX in both groups (P
