Disorders of sex development(DSD) include anomalies of sex chromosomes,gonads,reproductive ducts,and genitalia.Here,the term "intersex" is avoided because of its imprecision.The purpose of this review is to assist health care professionals in the provision of treatment,education,and support to children born with DSD and to their families.The goal of DSD treatment is to achieve the long-term physical,psychological,and sexual well-being of the patients.In the case of DSD it involves several principles.Providing medical and surgical care to deal with a complication that threatens to the patient's physical well-being;minimizing the potential for the patient and family to feel ashamed,stigmatized,or overly obsessed with genital appearance;delaying elective surgical and hormonal treatments until the patient can actively participate in decision-making;telling the truth to the family and the child and addressing psychosocial distress of the children and their parents.This approach is termed as "patient-centered".

With increasing demands and recognition, emergency medicine has advanced rapidly in China in recent decades. The education and training of professionals in this field are important for the further development of emergency medicine. With an attempt to investigate the way to strengthen residency training system in emergency medicine, this article reviews its potential development direction, training modes, learning materials, and quality control.

Exposure to thermal environment is one of the main concerns for manned space exploration. By focusing on the works performed on thermoregulation at microgravity or simulated microgravity, we endeavored to review the investigation on space thermal environmental physiology. First of all, the application of medical requirements for the crew module design from normal thermal comfort to accidental thermal emergencies in a space craft will be addressed. Then, alterations in the autonomic and behavioral temperature regulation caused by the effect of weightlessness both in space flight and its simulation on the ground are also discussed. Furthermore, countermeasures like exercise training, simulated natural ventilation, encouraged drink, etc., in the protection of thermoregulation during space flight is presented. Finally, the challenge of space thermal environment physiology faced in the future is figured out.

Objective To observe insulin synthesis and secretion in INS-1 under high glucose, and to clarify the effect of PTH1R. Methods After successful construction of recombinant PTH1R-siRNA vectors in INS-1 cell, insulin secretion and intracellular insulin content of control group, siPTH1R-Negative control group, PTHrP group, and siPTH1R group under 25 mmol/L glucose were measured by radioimmunoassay in INS-1 cell. Intracellular calcium were detected by Fluo-3/AM and the capability of glucose transport was calculated by assaying the uptake of [3H]-2-deoxy-D-glucose in cells.Results Compared with control group, and siPTH1R-NC group, PTHrP group showed increased capability of insulin secretion; PTHrP group had higher intracellular insulin levels than others; PTHrP group showed increased intracellular calcium; the uptake of [3H]-2-deoxy-D-glucose under high glucose after 48h of PTHrP group was increased(all P＜0.01). Conclusion There is a close relationship between PTH1R activation and insulin secretion and synthesis, PTH1R activation may be one of the protective mechanisms in maintaining function of β-cell under high glucose.

Objective To explore the expression of protein phosphotase-2A(PP-2A) in plasma in the patients with mild cognitive impairment. Methods The expression of PP-2A was measured by Western-blot in control group(n=11),1-year MCI group(n=10),2-year MCI group(n=10) and 3-year MCI group(n=10). Results The expression of PP-2A in 1-year MCI group(0.96±0.06) and in 2-year MCI group(0.93±0.07) was not obviously lower as compared with control group(1.00±0.08)(P>0.05),but a significant difference was induced between 3-year MCI group and control group(P<0.05),and between 3-year MCI group and 1-year MCI group(P<0.05),but wasn't between 3-year MCI group and 2-year MCI group(P>0.05). Conclusion Lower expression of PP-2A in plasma implies a possible value of MCI diagnosis.

Objective: To investigate the effects of bovine plasma fibronectin on the proliferation and differentiation of rat osteoblasts. Methods:Rat osteoblasts were cultured and identified. AlamarBlue were used to determine the effect of various concentration of bovine plasma fibronectin on the proliferation of the osteoblasts. ELISA method was used to determine the alkaline phosphatase activity of the cells. Results: Fibronectin stimulated the proliferation of rat osteoblasts at 40 ?g/ml (P
