Objective To explore the application of hysteroscopy in assisted reproduction. Methods A retrospective analysis was made on results of routine hysteroscopy in 150 cases of infertile women scheduled for assisted reproduction.Results Among the 150 cases,abnormal hysteroscopic findings were identified in 47 cases(31%),including endometrial polyps in 18 cases(12%),endometrial hyperplasia in 17 cases(11%),uterine deformity in 7 cases(5%),uterine adhesion and stenosis in 3 cases(2%),endometrial tuberculosis in 1 case(0.7%),and submucous myoma or adenomyoma in 1 case(0.7%).To think of hysteroscopic findings as the standard,the sensitivity,specificity,positive predicted rate,negative predicted rate,and accuracy were 66%(31/47),98%(101/103),94%(31/33),86%(101/117),and 88%(132/150) for transvaginal ultrasonography,respectively,and were 26%(12/47),100%(95/95),100%(12/12),73%(95/130),and 75%(107/142) for uterophotography,respectively.Conclusions Hysteroscopy is a simple and reliable way to explore the uterine cavity.It may be selected as a routine examination before assisted reproduction.

Objective To investigate the analysis of low calcium intravenous calcium supplementation agent and active vitamin D3 on total thyroidectomy on quality of life in patients with nodular goiter. Methods 40 cases of nodular goiter with total thyroidectomy were performed in our hospital from March 2014 to September 2016. It was randomly divided into control group and experimental group, 20 cases in each group. The patients in the control group were nodular thyroidectomy and the experimental group underwent total thyroidectomy. The quality of life of two groups of patients was evaluated by using the European five-dimensional health-related living quality scale (eq-5d). Results Two groups of patients, relevant questionnaire survey of the patient's ability to act, self-care ability, daily activity ability, pain or discomfort, anxiety, or depression, and the comparison of VAS score, according to the results of difference was not statistically significant. In comparison with ordinary people, the questionnaire survey results showed that the proportion of patients with moderate or above differences was higher and the difference was significant (P< 0.01). There was no statistical significance compared to the average person. Conclusion All patients with nodular goiter are treated with total thyroidism, and the effect is good, and the quality of life of patients is relatively small.

Objective To evaluate the effects of different doses of dexmedetomidine administered intranasally on the median effective concentration (EC50) of sevoflurane inhibiting responses to laryngeal mask airway (LMA) insertion in the pediatric patients.Methods American Society of Anesthesiologists physical status Ⅰ or Ⅱ pediatric patients of both sexes, aged 1-3 yr, with body mass index of 20-25 kg/m2, scheduled for elective surgery under general anesthesia, were randomly divided into 3 groups: control group (group C) , dexmedetomidine 1 μg/kg group (group D1) , and dexmedetomidine 2 μg/kg group (group D2).In D1 and D2 groups, dexmedetomidine 1 and 2 μg/kg (in 1 ml of normal saline) were administered intranasally at 1 h before induction of anesthesia, respectively.Group C received the equal volume of normal saline administered intranasally.The children were separated from their parents at 45-60 min after intranasal administration and admitted to the operating room.The children inhaled 8％ sevoflurane until they lost consciousness.After loss of consciousness, the end-tidal concentration of sevoflurane was determined using the modified Dixon's up-and-down method.The initial end-tidal concentration of sevoflurane was set at 2％.The concentration was increased/decreased by 0.2％ in the next patient according to the response to LMA insertion.The patient's sedation status and with LMA acceptance were evaluated, and the patient's satisfaction with sedation and with LMA acceptance was recorded.Probit analysis was used to calculate the EC50 and 95％ confidence interval of sevoflurane inhibiting responses to LMA insertion.Results The patient's satisfaction with sedation and with LMA acceptance was significantly higher in D1 and D2 groups than in group C, and in group D2 than in group D1 (P＜0.05).The EC50 (95％ confidence interval) of sevoflurane inhibiting responses to LMA insertion was 2.03％ (1.91％-2.15％), 1.76％ (1.65％-1.87％) and 1.63％ (1.53％-1.73％) in C, D1 and D2 groups, respectively.The EC50 was significantly lower in D1 and D2 groups than in group C, and in group D2 than in group D1 (P＜0.05).Conclusion Dexmedetomidine 1 and 2 μg/kg administered intranasally can decrease the EC50 of sevoflurane inhibiting responses to LMA insertion in the pediatric patients, and 2 μg/kg produces better efficacy.

AlM: To evaluate the effectiveness of Spot Vision Screener on vision screening of children without cycloplegia.METHODS:A total of 87 children (174 eyes) aged from 2~9 years old were examined with Spot Vision Screener and optometrist before cycloplegia.RESULTS: Statistical analysis demonstrated that the cylinder diopter and axis, the equivalent spherical diopter in both eyes, and the spherical diaopter in left eye had no significant change ( P>0. 05 ). However, the spherical diaopter in right eye had statistical significance. CONCLUSlON: Spot Vision Screener is a suitable instrument in vision screening of children without cycloplegia.
