This study was undertaken for the clinical analysis and evaluation on 121 patients with incompetent internal os of the cervix, who were admitted and treated with McDonald operation or Shirodkar operation at the Soonchounhyang Medical Center from January 1991 to December 1995. The results of this study were as follows : 1. The incidence of this IIOC was 1.1% of 11,116 cases of total delivery. 2. The mean age of IIOC was 31.7 years old. 3. The average number of gravida was 3.2. 4. The most common contributary factor was previous history of artificial abortion (51.2 %), and midtrimester abortion (17.4 %), cervical laceration due to previous vaginal delivery (8.3 %) etc. was followed. 5. The success rate of operation was 76 %, and the highest success rate (85.7 %) was reveald with period from 15th weeks to 16th weeks of gestation. 6. When cervical dilatation was abscent or small, the success rate of operation was high. 7. The factors of failed operation were preterm labor (58.7 %), PROM (34.5 %), and PIH, bleeding. 8. The delivery method after operation was vaginal delivery in 83 cases (68.6%) and cesarean section in 38 cases (31.4 %).

We report a case of prenatal diagnosis of fetal congenital goiter at 31weeks of gestation by ultrasonogram and fetal hypothyroidism confirmed at birth as thyroid function test by umbilical cord blood sampling. Maternal Graves' disease and the drugs used to treat hyperthyroidism in pregnant women can affect the fetus, causing hyperthyroidism or hypothyroidism and goiter. Fetal hypothyroidism may be caused by transplacental passage of either maternal thyrotropic-binding inhibitory immunoglobulin(TBII) antibodies or maternal treatment with propylthiouracil(PTU). Untreated fetal hypothyroidism may result in mental retardation, perceptual-motor, visual-spatial, and language developmental problems. In this article fetal thyroid function was not assessed by cordocentesis, but fetal congenital goiter was detected ultrasound. Ultrasound should be used to detect fetal goiter from 20 weeks onward. Fetal goiter should resolve when maternal PTU treatment is decreased. We have diagnosed fetal hypothyroidism in utero by ultrasonography. Significance of in utero management of fetal hypothyroidism is discussed.

OBJECTIVEA quantitative method was developed for the determination of tenuifolin in Tianwang Buxinwan and Guipiwan by HPLC.

METHODThe samples were separated by Alltima C18 column (4.6 mm x 250 mm, 5 microm) using methanol--0.05% phosphoric acid (65:35) as a mobile phase, flow rate was 1.0 mL x min(-1) and wavelength was set at 202 nm.

RESULTTenuifolin was detected in both Chinese preparations. The number of theoretical plates calculated by tenuifolin peak was 2 500. The regression equation of tenuifolin was Y = 5.239 x 10(6) X-6.247 x 10(5) (r = 0.9994) and the liner range was 10-500 g x mL(-1). The average recovery of tenuifolin was 97.5% (RSD less than 3.0%). The LOD of tenuifolin was 5.50 g x mL(-1).

CONCLUSIONThe method is sensitive, rapid and accurate.

The purpose of our experiment is to examine the level of anti-Haemophilus influenza polysaccharide antibody titer in the Korean population. Using ELISA, the level of Hib-PS antibodies in 384 infants and children who were all free from Hib invasive diseases, was tested. And the blood of 50 mothers within 24 hours of delivery and cord blood from their respective full-term neonates was also tested. The transport of Hib-PS IgG and IgG subclasses in paired sera from mothers and neonates was also measured. The titer of Hib-PS IgG varies with age. At birth the mean optical density of cord blood was 1.028; however, it declined to 0.609 up to 6 months and further decline was noted up to 2 years to 0.488. Then the mean O.D. remained around 0.5 from 3 to 14 years of age. The mean O.D. of Hib-PS IgG in the mothers blood was 0.856. The ratio of mean O.D. of anti-Hib PS IgG antibody in the cord blood to that in the maternal blood was 1.20. The mean optical densities of IgG subclasses were: 1.18 for anti-Hib PS IgG1, 1.07 for anti-Hib PS IgG2, 1.01 for anti-Hib PS IgG3, and 1.09 for anti-Hib PS IgG4. The sera from Korean children of almost all age groups reacted to Hib-PS antigen on ELISA. Also the active transport of anti-Hib PS IgG antibody through placenta was observed. Among four IgG subclasses, only IgG1 transport had significant experimental meaning.

Objective: To investigate the biological behavior spectrum of platelet-derived growth factor alpha receptor (PDGFRA)-mutant gastrointestinal stromal tumor (GIST), and to compare the clinical values of the Zhongshan method of benign and malignant evaluation with the modified National Institutes of Health (NIH) risk stratification. Methods: A total of 119 cases of GIST with PDGFRA mutation who underwent surgical resection at Zhongshan Hospital, Fudan University from 2009 to 2020 were collected. The clinicopathological data, follow-up records, and subsequent treatment were reviewed and analyzed statistically. Results: There were 79 males and 40 females. The patients ranged in age from 25 to 80 years, with a median age of 60 years. Among them, 115 patients were followed up for 1-154 months, and 13 patients progressed to disease. The 5-year disease-free survival (DFS) and overall survival (OS) were 90.1% and 94.1%, respectively. According to the modified NIH risk stratification, 8 cases, 32 cases, 38 cases, and 35 cases were very-low risk, low risk, intermediate risk, and high risk, and 5-year DFS were 100.0%, 95.6%, 94.3%, and 80.5%, respectively. There was no significant difference in prognosis among the non-high risk groups, only the difference between high risk and non-high risk groups was significant (P=0.029). However, the 5-year OS was 100.0%, 100.0%, 95.0% and 89.0%, and there was no difference (P=0.221). According to the benign and malignant evaluation Zhongshan method, 43 cases were non-malignant (37.4%), 56 cases were low-grade malignant (48.7%), 9 cases were moderately malignant (7.8%), and 7 cases were highly malignant (6.1%). The 5-year DFS were 100.0%, 91.7%, 77.8%, 38.1%, and the difference was significant (P<0.001). The 5-year OS were 100.0%, 97.5%, 77.8%, 66.7%, the difference was significant (P<0.001). Conclusions: GIST with PDGFRA gene mutation shows a broad range of biological behavior, ranging from benign to highly malignant. According to the Zhongshan method, non-malignant and low-grade malignant tumors are common, the prognosis after surgery is good, while the fewer medium-high malignant tumors showed poor prognosis after surgical resection. The overall biological behavior of this type of GIST is relatively inert, which is due to the low proportion of medium-high malignant GIST. The modified NIH risk stratification may not be effective in risk stratification for PDGFRA mutant GIST.
