Representative works:
She is the first Chinese director of obstetrics and gynecology at Peking Union Medical College Hospital and the only female among the first batch of academicians of the Chinese Academy of Sciences. Although Lin Qiaozhi remained unmarried throughout her life, she personally delivered more than 50,000 babies and was known as the “Mother of Ten Thousand Babies.” She has made contributions to the research on fetal intrauterine respiration, female pelvic diseases, gynecological tumors, and neonatal hemolytic disease, and is one of the founders of modern obstetrics and gynecology in China.

Lifetime Contributions:
Lin Qiaozhi is one of the pioneers of modern obstetrics and gynecology in China. She has made important contributions in clinical practice, scientific research and teaching.

Family Planning :
In 1956, when Lin Qiaozhi was recuperating in Qingdao, she presented to Mao Zedong the suggestion that population growth must be controlled. At that time, the Chinese Medical Association held its first academic conference on obstetrics and gynecology. As the chairman of the association and the host of the conference, she proposed the issue of family planning in accordance with Zhou Enlai’s instructions. In 1957, Ma Yinchu raised the strategic issue of population control at the fourth session of the first National People’s Congress. Lin Qiaozhi, Wang Shuzhen and others jointly made a written speech on strengthening family planning work, further clarifying the necessity and possibility of population control from a medical perspective, and proposing measures and methods for implementing family planning. In the 1960s, she established a scientific research team to undertake national key research projects and contraceptive device identification. The contraceptive dosage she specified became the standard dosage for oral contraceptives in mainland China. The research team cooperated with Beijing Obstetrics and Gynecology Hospital to successfully develop a metal and plastic hybrid contraceptive ring – the Beijing intrauterine device, which was eventually promoted and adopted nationwide due to its good contraceptive effect.

Cervical cancer:
Cervical cancer is a multiple gynecological disease. Because it is difficult for patients to detect in the early stages, it is often in the late stages when they seek clinical treatment. Lin Qiaozhi proposed conducting a cervical cancer screening in Beijing and conducting basic investigation and research. In 1958, with the cooperation of Zhang Chenfen, a census plan was formulated, and Dongcheng District of Beijing was selected as a pilot area, obtaining a large amount of survey data on 50,000 people. Then, with the participation of obstetrics and gynecology hospitals, the survey was expanded to include data from nearly 90,000 people. The results were published in the Chinese Journal of Obstetrics and Gynecology in 1960 under the title “Preliminary Report on the Results of Cervical Screening in 88,988 Residential Areas in Beijing”. Based on the experience of Beijing, 20 cities in China have successively examined more than 1.1 million women of childbearing age over the age of 25. The prevalence rate was 145/100,000, which was also the largest gynecological survey in the country at that time.
On this basis, Lin Qiaozhi’s team studied the causes of cervical cancer and significantly reduced its incidence and mortality rates. According to statistics from the Beijing area, the incidence rate from 1972 to 1976 was only 14.3% of that from 1958 to 1959; the proportion of early cancers discovered in cervical cancer increased from 5.5% to 43.7%, an increase of 8 times.

Choriocarcinoma:
In 1958, Lin Qiaozhi established a choriocarcinoma research group in the Department of Obstetrics and Gynecology of Union Hospital, with Song Hongzhao as the group leader, to conduct a series of studies on drug treatment of choriocarcinoma. By 1978, the research team had created a high-dose, multi-route medication method that cured most patients. According to the statistics of cases admitted to Union Hospital, the cure rate increased from 10% in 1959 to more than 80% in 1978; the cure rate of malignant hydatidiform mole was almost 100%. The successful treatment of chemotherapy drugs injected into the cerebral artery or intrathecally has reduced the mortality rate of patients with choriocarcinoma with brain metastasis from 100% in the past to less than 30%.

Genetic Diagnosis :
Due to genetic or other reasons, obstetric fetuses often have congenital malformations such as anencephaly, hydrocephalus, open spina bifida, pulmonary hypoplasia, congenital heart disease, and gastroschisis. In 1977, Lin Qiaozhi established China’s first prenatal diagnosis and consultation clinic for genetic diseases and genetic disease laboratory at Union Hospital. Sun Nianhu cooperated to set up a special research team to carry out prenatal diagnosis of fetuses from cytogenetics, enzyme science to molecular genetics. His “Amniotic Fluid Cell Culture” won the first prize of scientific and technological achievements of the Ministry of Health in 1981. “Early Pregnancy Chorionic Villus Diagnosis of Embryonic Chromosomal Abnormalities” won the second prize of the National Science and Technology Progress Award. “Preventive Eugenics” won the second prize for scientific and technological progress from the Family Planning Commission in 1986; “Prenatal Genetic Diagnosis of Hemophilia” won the second prize for scientific and technological progress from the Ministry of Health in 1991.

Hemolysis of the newborn:
Lin Qiaozhi was also the first to initiate transfusion therapy for neonatal hemolysis in China. In 1962, Lin Qiaozhi and her colleagues cured a newborn with hemolytic disease by whole-body transfusion via umbilical vein transfusion. This was the first successful case of neonatal hemolytic disease in China, and the treatment method was quickly promoted throughout the country. .
