BACKGROUND:At present, occlusion of the drainage tube was commonly used to reduce the drainage volume after total hip arthroplasty so as to promote the incision healing and hip function rehabilitation. However, the occlusion time is a problem deserving further investigations. OBJECTIVE:To research the effects of temporarily clamping drainage tube on drainage volume in early stage after total hip arthroplasty. METHODS:From January to October 2013, 112 patients received unilateral total hip arthroplasty in the First Ward, Department of Orthopedics, First Affiliated Hospital, Zhengzhou University in China. They were randomly divided into four groups according to the admission time (n=28):occlusion of the drainage tube for 2, 4 and 6 hours and without occlusion of the drainage tube. Al tubes were pul ed out in postoperative 48 hours. Moreover, 48-hour postoperative hemoglobin and drainage volume, the healing of incision and the score of hip joint function when patients were fol owed up at 1.5 months postoperatively were recorded accurately. RESULTS AND CONCLUSION:48-hour hemoglobin drop level and 48-hour incision drainage volume were highest in the non-occlusion group, fol owed by 2-hour occlusion group, 4-hour occlusion group and 6-hour occlusion group (P<0.05). However, no significant differences in the healing time of postoperative incision and the Harris score of hip joint function when patients were fol owed up at 1.5 months postoperatively were detected among groups (P>0.05). Incision infection and tension split were not seen in each group. Six cases affected subcutaneous ecchymosis and swel ing accompanied by pain and four cases suffered from the venous plexus thrombosis of the calf muscle in the 6-hour occlusion group. One case experienced fat liquefaction separately in the 4-hour occlusion group and non-occlusion group. These results suggested that temporary occlusion of the drainage tube in the early stage of total hip arthroplasty could reduce the drainage volume of incision. The suitable time of clamping drainage tube was 4 hours, and there were no adverse effects on healing of incision and recovery of hip function.

Objective To determine the effects of intrauterine growth retardation(IUGR) caused by malnutrition during pregnancy on the lung structure and expression of Clara cell protein (CCSP) and interferon (IFN)-γ in the fetal lungs,and to explore their relation ship with pulmonary disease.Methods Fetal rats from maternal protein-malnutrition dams were studied on day 20(term 21.5 day).The lung pathology was examined by means of Hematoxylin and eosin(HE) stain.Plasma was collected to determine the CCSP and IFN-γ concentration.Lungs were harvested to measure the expression of CCSP and IFN-γ mRNA by using fluorescent quantization reverse transcription (RT)-PCR and the levels of CCSP and IFN-γ protein were assessed by using enzyme-linked immunosorbent assay.Results Malnutrition fetus body weight significantly less compared to control group,so did the lung weight.However,lung weight,expressed as a percentage of body weight between the 2 groups was not different.The IUGR group had significantly decreased alveolar number manifested by lower radial alveolar count,and significantly increased mean linear intercept of alveoli.Both the CCSP mRNA expression and protein level in lung of IUGR rats were decreased compared with control rats (all P ＜ 0.05).A decline in plasma CCSP protein concentration was also noted compared with control group (P ＜0.05).Furthermore,IUGR group fetus showed lower IFN-γ levels both in circulation and in the lung tissue (all P ＜ 0.05).Conclusions Intrauterine malnutrition significantly alters lung structure and cytokine IFN-γ level,and the latter may further inhibit the transcription of CCSP gene.These alterations may contribute to both early and late postnatal respiratory morbidity.
