Integrative medicine follows the principles in TCM that nature and human beings being correspondent with its holistic and dialectic views and explores the integrating point with theories and scientific data in modern medicine. During study on 16 gynecological diseases, the deficiency. In patients with pubertal uterine bleeding, ovulation is induced by acupuncture via decrease in central β-endorphin (β-EP) levels, which leads to the cure of anorexia nervosa by acupuncture via decrease in serum cortisol levels in early 1980s. These results in TCM lead to the idea that neuro-endocrine system is directly related to metabolic system which is also proved to be true in the treatment of polycystic ovary syndrome (PCOS) with or without hyperinsulinemia by two formulas (Yu's Tonifying Ricipe and Tian Gui Recipe,TGR) respectively according to differential diagnosis in TCM. Ovulation resulted with decrease in obesity, acanthosis nigricans, serum androgen, insulin, leptin and hyperthalamic neuropeptide Y (NPY), proopiomalanocortin (POMC) levels based on scientific data from both patients and an animal modal. It suggests that metabolic network, and the incidence of obesity, hypertension, diabetes and cancers of the endometrium and breast may be reduced among patients with PCOS in their future life while these recipes being taken long period. For perimenopausal syndrome, formula Geng Nian Chun (GNC)without increase in serum estrogen levels. In aging rats, it was found that GNC increased the ER and ERmRNA expressions in the ovarian axis and the spleen accompanying with increase in central β-EP, serotonin (5-HT) and peripheral interlutin-2 (IL-2) levels in aging rats without changes of estrogen levels. These data may refer to the release of symptoms in women with postmenopausal syndome. It suggests that GNC up-regulates the fading of neuro-endocrine-immune network. Prevention, alleviation of osteoporosis, cardiovascular disease and Alzheimer disease may be expected in aging women with long period taking GNC. 展开更多

Background: Trampoline use is one of the most common causes of recreational injury in children. In recent years, trampoline parks have grown in popularity and may be altering the spectrum of the trampoline-related injuries that occur. These parks create increased opportunity for injuries that appear uniquely different from accident patterns seen with home trampoline use. Recent work has suggested this may result in injuries occurring in greater frequency and with increased severity that may result in a greater need of hospital admission and procedural management by subspecialty services. Case Series Presentation: This case series presents three such examples occurring after the opening of a trampoline park in our local community: 1) A displaced forearm fracture requiring closed reduction and orthopedic follow-up;2) An ankle fracture necessitating operative reduction and fixation;and 3) A facial injury with tooth avulsion prompting oral surgery consultation and endodontic follow-up. Conclusions: These cases demonstrate the complexity and severity of injury that can occur from trampoline park participation and should serve to increase awareness among health care providers of these risks to provide appropriate parental counseling and advocate for preventative measures. 展开更多

BACKGROUND Femoral neck stress fractures(FNSFs)are commonly found in long-distance running athletes.For FNSFs,early diagnosis and proper treatment are important.The objective of this study was to report FNSFs that occurred after excessive exercise using trampoline in middle-aged women.CASE SUMMARY The patient was a 43-year-old woman who exercised jumping on a trampoline for 6 wk for 1-3 h a day to diet.Exercise includes repeated flexion-extension of the hip joint.The patient was admitted to the hospital due to sudden bilateral groin pain that occurred suddenly during a trampoline exercise.Hip magnetic resonance imaging(MRI)revealed bilateral FNSFs.After 2 wk of follow-up with conservative treatment,the pain slightly decreased.However,it did not disappear completely.It was determined that it was difficult to control symptoms only by conservation treatment.Thus,closed reduction and internal fixation using a cannulated screw were performed for the more painful left hip joint.After operation,the pain was improved.Walking using crutches was possible.Followup MRI showed that the right femoral head signal was decreased compared to the left femoral head signal.Therefore,nonsteroidal anti-inflammatory drug and conservative treatment were provided.CONCLUSION In middle-aged people,excessive trampoline exercise can repeat hip flexion and extension for a short period of time,leading to FNSFs. 展开更多

The liberation of women is the historical process in which women have striven for gender equality, freedom from oppression, confinement and discrimination, and are becoming the masters of the society and their own destinies. According to the diversity in history and the state, the process can be divided into a serial of correlated phases, with each phase focusing on different issues. Sexism order in China had remained stable in the traditional society for centuries through a set of institutions. Women had believed in a sexual order and the rules of propriety, which advocated that men were superior to women. After the People’s Republic of China was founded in 1949, women’s rights in politics, economy, society, and even family were recognized and secured by the Constitution and laws just as men’s during a short period. Women’s liberation in China has made a significant progress. 展开更多

The legal confirmation process of women’s human rights has been undergoing great difficulties both in the United Nations and among nations. The Fourth World Conference on Women plays a role in promoting the legal protection of women’s human rights. Currently, the protection of women’s human rights has undoubtedly become the consensus of both international and domestic law. International conventions on human rights have become an important launching area for promoting international law on women’s human rights, owing to its legal binding force and supervising mechanism established under it. Domestic law has also become the first line of defense for protecting women’s human rights. However, it needs to be pointed out that, for international conventions on human rights and domestic legislation, the cognition and acceptance of social gender conception has not only promoted changes on forms, but, more importantly, on revolution at substantial level. 展开更多

Women's rights are essential human rights recognized by the international covenants on human rights and protected in the constitutions and laws of countries.In the context of implementing the three-child policy in China,women are facing pressures from childbearing and bringing up children as well as trying to have a career.It is clearly stipulated in Article 49 of China's Constitution"the mother is protected by the state,"the constitutional principle of equality of men and women shall be incorporated into the interpretation of this article,fully respecting women's subjectivity and equal rights and affirming the social benefits of childbearing and bringing up children.With the introduction of the three-child policy,the protection of women's rights shall focus on their reproductive rights,right to health,right to work and equal rights within the family.The system of women's rights is complex,relates to identity and must be open to the future.The state has the obligation to fully respect,actively promote and promote in a narrow sense the realization of women's rights.To better coordinate the implementation of the three-child policy and the protection of women's rights,we should introduce the concept of social gender equality,improve the system ofp ublic childcare services,home care leave and equal employment,and promote the implementation of relevant laws and policies with special attention being paid to women in rural areas and single mothers. 展开更多
