AIM: To establish the capillary GC method for separating and determining both camphor and menthol in Compound Dexamethasone Acetate Cream. METHODS: The methyl salicylate was used as internal substance and the sample solution was prepared by extracting with anhydrous ethanol at(60 ?C.) The GC test conditions consisted of Agilent HP-INNOWAX(30 m?0.320 mm?0.25 ?m) as the stationary phase,nitrogen as the carrier gas,split ratio of 25.0(∶)1.The flow rate was 1.5 mL/min,column temperature was at 145?C,inlet temperature was(200 ?C),FID detection was(250 ?C),injection volume was 0.6 ?L. RESULTS: The linearities of camphor and menthol were good,in the range of 0.303-3.030 g/L with r=0.999 9 for camphor and in the range (0.306)-(3.060) g/L with r=0.999 9 for menthol.The average recoveries of high,middle and low three concentrations for menthol were 100.6%,100.2%, 99.7%;RSD was 0.58%,0.65%,0.88% and for camphor were 100.3%,(99.8%),(97.8%);RSD was 0.43%,0.78%,1.0%. CONCLUSION: This method is convenient,rapid,accurate and reproducible,and can be used for quality control of Compound Dexamethasone Acetate Cream.

This paper reports clinical and cytogenetic studies on 20 cases of congenital ovary dysgenesis (Turner syndrome). The clinical studies included the history, physical and pelvic examinations, blood FSH, LH and estradiol determinations, and pneumoperitoneography, Cytogenetic studies on the karyotype of lymphocytes were performed with G,C banding and high resolution chromosome banding techniques. There were karyotypes with 45,X in 12 cases,46, XX/45,X in 2 cases, 45,X/46,XX/46,XXp- in 2 cases, 45, X/46,Xi (Xq) in 2 cases,45,X(Xqace) in one case and 46,Xi(Xq) in one case. One of these patients (46,XX/45,X) had a term pregnancy, and a girl has grown well. Treatment was mainly low-dose estrogen replacement therapy with cyclic administration of progesterone. These patients were followed up from four months to 20 years. Six of them were married with normal sexual activity. The patients' height was increased by 2 to 10 cm after treatment. It is concluded that the supporting treatment is beneficial whenever the diagnosis is made.

Objective To study the effects of different oxytocin doses on neonatal pathologic jaundice.Methods A total of 386 newborn infants with normal term of labor were selected from the full-term pregnant women who were admitted to Jiaxing Maternal and Child Health Care Hospital from August 2014 to September 2015 were divided into low dose group (2.5 ~5.0U,n=96), middle dose group (5.0 ~7.5U,n=96), high dose group (7.5~10.0U,n=96) and control group (n=98) according to the different dosage of oxytocin.Total labor time, neonatal gender, neonatal weight and maternal age, as well as the day of birth within seven days of skin side of the bile values were recorded.The probability of each group of neonatal patients with pathological jaundice and the relationship with oxytocin doses were studied.Results The incidence of neonatal pathologic jaundice was 3.23%in the low dose group, 6.67%in the middle dose group, 29.73%in the high dose group and 3.16%in the control group.The differences among low dose group, middle dose group and control group were not significan.Compared with high dose group, the incidence of neonatal pathologic jaundice in low dose group, middle dose group, and the control group were all lower(P<0.05).Conclusion Oxytocin less than 7.5U in labor has no significant effect on neonatal pathologic jaundice, >7.5U can promote pathologic jaundice.

Objective:To study the instant and short term effects of diagnostic ultrasound on ultrastructure and hydrogen peroxide cytochemistry of human villi. Methods: Fifteen healthy women with gestational ages of 6 to 8 weeks were divided into 4 groups. Group A( n =3),B( n =4),C( n =4) and D( n =4) were exposured to diagnostic ultrasound for 0,10,20 and 20 min respectively. In group A, B, and C, the villi were taken out immediately after ultrasound exposure and were studied. In group D, the villi were taken out 3 d after ultrasound exposure. Results: The results showed that there were changes only in group C. Enlargement of endoplasmic reticulum and mitochondrial intracristal space were observed in syntrophoblast cells. In group A, B, and D, there were no evident abnormality. Conclusion: The conventional acoustic exposure of diagnostic ultrasound is safe for human villi.
