ABSTRACT
Objective:To translate the English version of Sexual Interest and Desire Inventory-Female (SIDI-F) into Chinese, evaluate its reliability, validity and the proper cut-off point of diagnosis of hypoactive sexual desire disorder (HSDD) in China.Methods:Chinese version of SIDI-F was developed and 96 healthy women from January 1, 2019 to December 31, 2019 in Taihe Hospital, Shiyan City, Hubei Province were selected to fill in the Chinese version of SIDI-F and the Female Sexual Function Index (FSFI). Next, analyzed the reliability, validity and the cut-off point of diagnosis of HSDD of the SIDI-F.Results:The Cronbach coefficient of the Chinese version of SIDI-F was 0.931, split-half reliability was 0.922, the intra-group correlation coefficient was 0.805. Analysis of content validity of the SIDI-F indicated that the average of scale-level content validity index was 1.00, the item-level content validity index was 1.00, and the Pearson correlation coefficient between the score of SIDI-F and the erotica score of the FSFI (FSFI-D) was 0.802. Factor analysis of the Chinese version of SIDI-F showed good construct validity. The area under ROC was 0.835. With the SIDI-F score and the best cut-off point of 26.5, Youden index was the largest, at 0.635. The validity indicators were 76.7% for sensitivity, 86.8% for specificity, 5.95 for positive likelihood ratio.Conclusions:The Chinese version of SIDI-F has high reliability and validity in Chinese population, and these show 26.5 point can be used as the best cut-off value of diagnose HSDD.
ABSTRACT
OBJECTIVE：To prepar e Celastrol oral u lcer film ，and to evalute its quality primarily. METHODS ：The comprehensive scores of the appearance ，film formation and toughness of the drug film were used as indicators ，and the amount of celastrol was controlled to 0.05％. Orthogonal test was used to optimize the amount of excipients as starch ，sodium carboxymethyl cellulose，glycerol and condensed honey ，so as to optimize the formulation ；the validation test was performed. The adhesion force of the film prepared by the optimal formulation were determined. UV spectrophotometer was used to detect the content of celastrol in the film. RESULTS ：The optimal dosage of each excipient in Celastrol oral ulcer film was starch 1.0 g，sodium carboxymethyl cellulose 0.2 g，glycerin 0.4 g，condensed honey 1.5 g. In 3 times of validation tests ，the appearance of the prepared film was good. The average adhesion of the film prepared by the optimal formulation was 4.2 g，and the average content of celastrol was 0.135 3 mg/cm2（RSD＝1.90％，n＝3）. CONCLUSIONS ：In this study ，the best formulation of Celastrol oral ulcer film was optimized，and the film forming ability of the prepared film is good and the quality is stable and uniform.
ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the feasibility of establishing a mouse model of ovarian oxidative stress by intraperitoneal injections of arsenic sodium.</p><p><b>METHODS</b>Twenty adult female Kunming mice were randomized equally into the normal control group and ovarian oxidative stress model group for intraperitoneal injections of 0.5 ml distilled water and 8 mg/kg arsenic sodium solution every other day, respectively. After 8 injections, the mice were sacrificed for histological observation of the ovarian sections and enzyme-linked immunosorbent assay (ELISA) of serum estradiol (E(2)) and pregnenedione (P) levels ande contents of reactive oxygen species (ROS) , malondialdehyde (MDA), superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) in the ovary homogenate.</p><p><b>RESULTS</b>Numerous atretic follicles were found in the ovaries of mice in the model group with obviously reduced growing follicles. Compared with those in the normal control group, the contents of ROS and MDA increased and SOD and GSH-Px levels in the ovarian homogenate decreased significantly in the model group (P<0.05).</p><p><b>CONCLUSION</b>A mouse model of ovarian oxidative stress can be established by intraperitoneal injections of arsenic sodium.</p>
