This study was aimed to observe four kinds of kidney-tonification medicine, which were Epimedium, pso-ralen, Ligustrum lucidum, Polygonum with the active ingredient of icariin, psoralen, oleanolic acid, stilbene glucoside and their orthogonal compatibility. There were two kinds of non-kidney tonification medicine, which were Chuanx-iong and astragalus with the active ingredient of TMP and astragaloside. The observation was made on the regulatory role of rat bone marrow stem cells (BMSCs). A total of 65 SD rats were randomly divided into the normal control group, positive transformed control group, kidney-tonification compatibility group (including Group 1, Group 2, Group 3, Group 4, Group 5, Group 6, Group 7, Group 8, and Group 9), non-kidney tonification medicine control group (in-cluding TMP group and astragaloside group). Intragastric administration of medication was given to the kidney-tonifi-cation compatibility group and the non-kidney tonification medicine control group, once a day for 3 consecutive days. Intragastric administration of equal amount of normal saline was given to the normal control group and the posi-tive transformed control group. On the third day of intragastric administration, rats in each group were sacrificed. Serum containing medication was used in the culture of BMSCs for 6, 12, or 18 days. ELISA method was used to quantitatively detect the expression activity and content of BMP2 on the 6th, 12th, or 18th day, in order to evaluate the degree of bone cell differentiation degree. Real-time quantitative PCR method was used for detection of expression of Bmp2, Smad1, Smad4 mRNA in serum containing medication in the culture of BMSCs on the 18th day. The results showed that the kidney-tonification compatibility can improve the expression activity and content of BMP2 culture in vitro, with the peak on the 12th day. The kidney-tonification compatibility groups can upregulate expressions of Bmp2, Smad1, Smad4 mRNA. It was concluded that the active ingredient compatibility of kidney-tonification medicine can promote BMSCs. Its mechanism may be related to the upregulation of expression of Bmp2, Smad1, Smad4 mRNA, and the activity and content of Bmp2.

Objective To assess the effects of different administration timing of prophylactic antibiotics on infections after hip arthroplasty. Methods 535 patients having undergone arthroplasty were divided into two groups: the experiment group (n=273)and the control group (n=262): The former groupwere administered with antibiotics until 24 hours postoperatively and the latter until 72 hours postoperatively. The two groups were compared in terms of postoperative infection rate. Results The infection rates in the experimental groupand the control group were 4.396%and 3..817%, with insignificant differencebetween them. Conclusion For those patients undergoing hip arthroplasty, extended administration of antibiotics after operation (over 48 hours) may not reduce the risk of recent the infection rate.

Copper is an important trace element in the human body, and copper deficiency or overload can lead to a series of body dysfunctions. This review focuses on hepatolenticular degeneration and related diseases of abnormal copper metabolism. Hepatolenticular degeneration has various clinical phenotypes, and related diseases, such as cholestatic liver disease, hereditary ceruloplasmin deficiency, and congenital abnormal glycosylation, may bring confusion to the clinical diagnosis of hepatolenticular degeneration. With reference to the latest research advances and experience in the diagnosis and treatment of hepatolenticular degeneration, this article discusses the pathogenic mechanism and clinical diagnosis of hereditary abnormal copper metabolism from the perspective of liver diseases.

The clinical phenotype of genetic liver disease is significantly different. Although the incidence of disease is low, because of the wide spectrum of diseases, the overall affected population is not rare. Therefore, clinical concern is a matter of alarm. Additionally, these diseases rarity in clinical practice has covered the recognition, causing increased problem of clinical misdiagnosis. In accordance with the problems encountered in clinical practice of our hospital, we explore the clinical diagnosis of genetic liver disease.
