Objective To investigate the effects of dexmedetomidine pretreatment on lung injury for patients after liver surgery. Meth-ods Sixty patients who had liver surgery in our hospital from August 2009 to February 2014 were equally divided into the treatment group and the control group, with 30 patients in each group. Both of the two groups were given one-lung ventilation anesthesia. Patients in the treatment group were given continuous intravenous infusion of dexmedetomidine after induction of anesthesia while paitents in the control group were not. In the time of before induction of anesthesia (T0), closed chest (T1), immediately after surgery (T2), all patients were given the gas analysis, expression of inflammatory cytokines and lung function testing and analysis. Results The diastolic blood pressure and heart rate at time points of T0, T1 and T2 in the two groups showed no significant difference (P> 0. 05). And the expression of TNF-αand SP-D at time points of T1 and T2 in the two groups were significantly higher than those at T0 (P<0. 05);while the expression of TNF-αand SP-D in the treatment group were significantly lower than those in the control group at time points of T1 and T2 (P<0. 05). The plateau air-way pressure and airway resistance in the treatment group at T2 and T3 were significantly lower than that at T1 (P<0. 05), and there were statistically significant differences compared with the control group (P<0. 05). Conclusion The dexmedetomidine pretreatment for the liver surgery patients can inhibit the inflammatory response, while improve lung airway plateau pressure and airway resistance. It has no significant effect for blood, so it can play a protective role for lung function.

Objective To investigate the influences of Xuebijing injection on organs' ultra-microstructure in septic shock rats. Methods Fifteen male Sprague-Dawley (SD) rats of clean grade were selected. According to the method of random digits table, all of them were divided into three groups: sham operation group, model group and Xuebijing treated group, 5 rats being in each group. Cecal ligation and puncture (CLP) was adopted to reproduce abdominal cavity infection leading to sepsis model formation. While the rats in sham operation group just underwent abdominal median incision, abdominal exploration and closure of abdominal wall after flipping retrocecal region. In the Xuebijing treated group, within 1 hour after the operation, Xuebijing injection (4 mL/kg) was transfused through the catheter inserted in the femoral vein, and then normal saline (2 mL·kg-1·h-1) was continuously transfused until the rat being sacrificed. In the sham operation group and model group, equal volume of normal saline was given after operation. The blood pressure of all the rats was monitored continuously by a pressure device connected with a catheter inserted in the right carotid artery. The rats were observed for 12 hours, afterwards they were sacrificed, the samples of heart, lung, kidney and liver were taken, and their ultrastructural changes were observed under an electron microscope. Results The blood pressure of sham operation group was decreased a little with time extension, but within normal limits. The mean arterial pressure (MAP) of model group and Xuebijing treated group developed into a state of sepsis shock at 9 hours and 10 hours after operation respectively, and MAP were lower than 70 mmHg (1 mmHg=0.133 kPa). The MAP levels of model and Xuebijing groups at 11 hours after operation were lower significantly than those of sham operation group (mmHg:58.7±7.0, 58.7±8.3 vs. 91.0±8.2, both P<0.01), and they were persistently decreased at 12 hours after operation;the MAP in Xuebijing group was a little higher than that of model group at the same period (mmHg:55.4±4.0 vs. 48.8±12.9, P>0.05). The results of the observation with electron microscope:the structures of heart, lung, liver and kidney in sham operation group were basically normal;all the organs of model group appeared different degrees of structural damage. Compared with model group, the injury of heart and lung in Xuebijing treated group was milder, especially, the changes of cellular mitochondria were obvious;however, there was no significant difference in injury of kidney and liver between the model and Xuebijing treated groups. Conclusion Xuebijing injection can play a certain role in stabilizing the circulatory system in rats with septic shock, and can possibly ameliorate the heart and lung damage caused by infection and shock.

Objective To investigate the protective effect and possible mechanisms of erythropoietin (EPO) on myocardial ischemia-reperfusion injury(MIRI) in rats.Methods Ninety male SD rats were randomly divided into three groups,the sham operation group (n =20),I/RI group (n =20),and EPO treatment combined I/RI group (n =20).The left anterior descending coronary artery was ligated for 30min utes and then loosed for 150min utes to establish the rat model of MIRI.Rats of EPO + I/RI group were injected with EPO(5000u/kg) in abdominal cavity,the others were injected with nomal sodium.The serum MDA content was determined in a method of the thiobarbituric (TBA),the cardiac injury markers(cTn Ⅰ,CK,CK-MB) contents were determined by ELISA.Results The serum MDA and MPO levels of the I/RI group were significantly higher than the sham group,difference was significant(t =10.445,9.848,all P ＜ 0.05) ; Intervention by EPO,the serum MDA and MPO levels of the EPO + I/RI group were significantly lower than the I/RI group,the difference was significant (t =5.087,6.683,all P ＜ 0.05).The serum cTn Ⅰ,CK and CK-MB levels of the I/RI group were significantly higher than the sham group,the difference was significant (t =8.153,5.411,3.729,P ＜ 0.05) ; Intervention by EPO,the serum cTn Ⅰ,CK and CK-MB levels of the EPO+ I/RI group were significantly lower than the I/RI group,the difference was significant(t =4.808,4.089,3.002,all P ＜0.05).Conclusion EPO has protective effect on MIRI,the effect may be through EPO's antioxidant,antiinflammatory and protective effect on myocardial cells in the MIRI rats.

Background Matrix metalloproteinases (MMPs) play important roles in the formation of choroidal neovascularization (CNV),but its mail origin is not ocular cells in situ.Bone marrow-derived cells (BMCs) participate in the formation of CNV and is probably a primary source of expressing MMPs in CNV.MMP-2/MMP-13 is speculated to be the regulating target genes of miR188-5p.Objective This study was to verify whether BMCs are the main source of MMPs,and whether the MMP-2/MMP-13 expression is potentially regulated by miR188-5p.Methods BMCs expressed green fluorescent protein (GFP) from transgenic female C57BL/6J mice were transplanted to female wild-type C57BL/6J mice to establish C57BL/6J.GFP chimeras models,and 42 mice with chimerisms more than 85％ by flow cytometry were included as the experimental group.Other 42 wild-type C57BL/6J mice without the BMCs transplantation were enrolled as the control group.CNV was induced by laser coagulation of retinas on the mice of both groups.MMP-2/MMP-13 levels in the retinochoroid tissue were quantified by ELISA at day 1,3,5,7,10,14,and 28 after photocoagulation.The expression of miR188-5p mR NA in the retinochoroid tissue was assayed by real-time quantitative PCR (RT-qPCR).Immunofluorescence stain and fluorescent in situ hybridization were used to identify the MMP-2/MMP-13 and miR188-5p expressed by GFP-positive BMCs in CNV,and the expression level was quantified by images analysis.Results The proportion of GFP+ mouse mononuclear cells was (90.67±3.02) ％ in the C57BL/6J.GFP chimeras.The concentration changes of MMP-2/MMP-13 in retinochoroid homogenate showed a same tendency with the lapse of time between the experimental group and the control group (MMP-2:F=0.060,P =0.810 ; MMP-13:F =0.012,P =0.915).The expression level was zoomed in retinochoroid tissue after induce of CNV with the maximal value on the third day in both groups,and the proportion in the experimental group was 64.21％ ;while the expression level of MMP-13 was slowly raised after induce of CNV with the peak at the seventh day,and the proportion in the experimental group was 79.61％.A complementary association point of miR188-5p was exhibited in the 3 '-untranslated regions of MMP-2 or MMP-13 by target gene prediction.The expression level of miR188-5p mRNA in the BMCs of CNV area was sharply declined after induce of CNV with the lowest value on the seventh day.A negative correlation was found between the expressing level of miR188-5p and MMP-13 protein (r=-0.868,P＜0.05) as well as early stage of expression level of MMP-2 protein (r=-0.997,P＜ 0.05).Conclusions The elevation of MMP-2/MMP-13 expression levels is associated with the formation of CNV,and the regulation of miR188-5p expression in the BMCs of CNV area is responsible for increase of MMP-2/MMP-13 expression.The tendency of miR188-5p expression is inversed with MMP-2/MMP-13.

Gastroenteropancreatic neuroendocrine neoplasms are a group of heterogeneous tumors originated from the gastrointestinal peptidergic neurons and neuroendocrine cells.Rectum is one of the major sites of gastroenteropancreatic neuroendocrine neoplasms.Although the progression of rectal neuroendocine neoplasms (rNENs) is relatively slow,metastasis could occurs and liver is the major target organ invaded by distant metastatic rNENs.Surgical operation can be used as the preferred method for the treatment of rNENs and its metastasis at present.If the clinical situations of tumors are not eligible for the operation,interventional treatment can be considered as an alternative treatment.The chemotherapies and molecule-targeted drugs for rNENs are primarily in the light of therapeutic methods for pancreatic neuroendocrine neoplasms,it may help patients achieve partial response or stable disease,and prolong patients survival time.However,there has been few clinical researches directed toward rNENs and no an extensive consensus for treatment of rNENs up to now,and more evidences of evidence-based medicine should be necessitated.This paper has discussed and summarized treatment progression of rNENs and its metastasis.

Myocardial fibrosis is the pathological basis of hypertensive heart disease, which is the key to control cardiovascular complications. Traditional Chinese medicine (TCM) has the advantage of targeting many components of a system and providing more integrated regulation than modern medicine. While, modern medicine tends to target a single pathological link. This study was aimed to investigate effects and mechanisms in the treatment of myocardial fibrosis in hypertension with TCM from a different perspective, which provided references for clinical treatment.

Objective To investigate the impact of rivaroxaban and low molecular weight heparin on hidden blood loss after unilateral first half artificial hip replacement surgery.Methods According to the digital table,a total of 80 cases because of femoral neck fractures in elderly patients with unilateral arthroplasty artificial hip and a half after surgery were randomly divided into the rivaroxaban group and low molecular weight heparin (LMWH) group,40 cases in each group.In both groups,respectively,after 12 h begin daily oral rivaroxaban 10 mg and subcutaneous low molecular weight heparin 5 000 u,compared the two groups around the actual amount of perioperative blood loss,blood loss was dominant,recessive blood loss and hidden blood loss accounts,the actual percentage of total blood loss,and recorded 35d bleeding events.Results The total amount of blood loss,dominant blood loss,hidden blood loss and the hidden blood loss accounted for the actual percentage of the total amount of blood loss of the rivaroxaban group were (671.00 ± 55.61) mL,(313.88 ± 14.53) mL,(350.00 ± 29.41) mL,(52.00 ± 5.22) ％,respectively,which of the the LMWH group were (662.00 ± 30.19) mL,(288.87 ± 15.33) mL,(372.00 ± 35.10) mL,(56.00 ± 6.71) ％,there were no significant differences between the two groups (t =0.93,0.93,0.83,1.03,all P ＞ 0.05).Conclusion For patients first underwent unilateral hip replacement surgery artificial half,perioperative using rivaroxaban or LMWH has no significantly differences in hidden risk of bleeding and bleeding event rate.
