Objective To compare the recessive and dominant blood loss and total blood loss during the perioperative period between proximal femoral nail antirotation(PFNA)and artificial femoral head replacement in the treatment of Evans Ⅲ,Ⅳ type femoral intertrochanteric fractures for providing clinical evidence on selection of operative methods. Methods A retrospective study was conducted to analyze 61 older hospitalized patients with Evans Ⅲ,Ⅳ type femoral intertrochanteric fractures in Jimo City Traditional Chinese Medical Hospital from January 2009 to September 2014.The PFNA was adopted in 33 cases and the artificial femoral head replacement in 28 cases.The dominant blood loss was recorded,and total blood loss and recessive blood loss in the two groups were calculated by Gross equation according to the dominant blood loss,body height,body weight and hematocrit of pre-and post-operation. Results The average dominant blood loss in the intraoperative period was much less in the PFNA fixation group(106.2 ± 53.8)ml than in the artificial femoral head replacement group(274.6 ± 80.3)ml(P<0.05).The average recessive blood loss in the perioperative period was much less in artificial femoral head replacement group(577.0 ± 52.2)ml than in PFNA group(821.8 ± 69.5)ml(P<0.001).The total blood loss during the perioperative period was not significantly different between proximal femoral nail antirotation(896.0 ± 227.5)ml and artificial femoral head replacement(908.6 ± 204)ml(P>0.05). Conclusions There is obvious difference in the dominant blood loss between PFNA and artificial femoral head replacement for treatment of Evans Ⅲ,Ⅳ type femoral intertrochanteric fractures in the elderly patients.The proper operative method should be chosen based on the general condition of the elderly and fracture types.

In the context of the digital economy， the operational relationship between traditional Chinese medicine （TCM） and Internet healthcare organizations as well as related governance institutions has attracted much attention. As the market scale of the Internet healthcare has continued to grow in recent years， the quality of Internet TCM healthcare has also been improved. By analyzing the development status of Internet TCM healthcare， it is proposed that Internet TCM health service should seize the opportunities and challenges in future， promote the growth of market scale from varied aspects， enhance patient-centered care awareness， and strengthen the promotion and popularization of digital services， thereby promoting the high-quality development of Internet TCM health service in the context of the digital economy.

The main pathogenesis of chronic cough in children is the disorder of ascending and descending of qi movement caused by healthy qi deficiency and pathogenic qi retention. The deficiency of lung， spleen， and kidney is the root of the disease， and the retention of phlegm-fluid， food accumulation， and fire from constraint is the branch pathogenesis of the disease. In the treatment， we should reinforce and tonify healthy qi， dispel pathogen and regulate qi， with Yupingfeng Powder （玉屏风散） as the basic prescription. For lung qi deficiency syndrome， modified Yupingfeng Powder could be used for supplementing lung to consolidate the exterior； for lung and spleen qi deficiency syndrome， modified Yupingfeng Powder plus Shenling Baizhu Powder （参苓白术散） could be used for supplementing lung and fortifying the spleen， treating with both supplementation and transformation； for lung kidney qi deficiency syndrome， modified Yupingfeng Powder combined with Suzi Jiangqi Decoction （苏子降气汤） could be used for supplementing lung and replenishing kidneys， absorbing qi to the root. All the above prescriptions could combine the method of dispelling phlegm， promoting digestion and guiding out food stagnation， soothing the liver and draining fire to remove the solid pathogens， in order to treat the root and branch simultaneously， and the cough will stop if the ascending and descending of qi movement recover as usual.
