Therapeutic hypothermia has been shown to improve neurological outcomes after global ischaemia/hypoxia in patients who have had cardiac arrest. Therapeutic hypothermia is one of the most extensively studied and influential therapeutic strategies of acute ischemic stroke. Previous studies of therapeutic hypothermia mainly focused on whole-body cooling. However, delayed induction and systemic complications have limited the clinical application of whole-body cooling. As a selective cerebral hypothermia, the selective intra-arterial brain hypothermia treatment has the characteristics of rapid and even induction of hypothermia, and less affecting the core body temperature. Therefore, it has become a promising treatment modality. This article reviews the application of selective intra-arterial brain hypothermia in acute ischemic stroke and its advantages and limitations in order to provide reference for further experimental studies and future clinical trials.

Objective To review the indications,surgical methods,and matters which need attention in partial right diaphragmatic resection,and to summarize our experience of surgical therapy for hepatocellular carcinoma with right diaphragmatic invasion.Methods The clinical data of 27 patients with hepatocellular carcinoma which had invaded the diaphragm and had received partial right diaphragmatic resection and partial hepatectomy in our hospital from September 2008 to September 2012 were retrospectively analyzed.Results The operations were all performed successfully.The tumor diameter ranged from 5.0 to 15.0 cm (average 8.5 cm).The area of right diaphragm which was resected ranged from 9.0 to 50.0 cm2 (average 28.5 cm2).The operation time was 110～250 min (average 165 min),and blood loss was 450～2600 ml (average 870 ml).Diaphragmatic invasion was confirmed by postoperative histopathology in 9 patients (33.3％).A small quantity of right thoracic effusion was detected in all the cases postoperatively.Other complications included hepatic insufficiency in 4 patients and early postoperative bleeding,upper gastrointestinal bleeding,biliary fistula,and infection under the diaphragm in 1 case each.All patients recovered after conservative treatment.There was no perioperative death.19 patients received other postoperative adjuvant treatment while 6 patients refused further treatment and 2 patients were lost to follow-up.The 0.5-,1-,2,and 3 year survival rates after operation were 92.6％,81.5％,51.9％ and 33.3％ respectively.Conclusions Right diaphragmatic invasion is not a contraindication to surgery.Right diaphragmatic resection was safe and feasible,and postoperative long-term survival was satisfactory.

Objective:To investigate the effect of huaier granule combined with docetaxel + epirubicin + cyclophosphamide (TEC) neoadjuvant chemotherapy on the disease control rate and the levels of extracellular fragment of human epidermal growth factor receptor 2 (HER2-ECD) and tumor abnormal protein (TAP) in patients with advanced breast cancer.Methods:From April 2013 to June 2016, 94 patients with advanced breast cancer in Shengjing Hospital Affiliated to China Medical University were selected and randomly divided into observation group ( n=47) and control group ( n=47). The control group was treated with TEC neoadjuvant chemotherapy, and the observation group was treated with TEC neoadjuvant chemotherapy combined with huaier granules for 12 weeks. The curative effect, incidence of adverse reactions, cellular immune function indexes (CD8 + , CD4 + , CD4 + /CD8 + ), serum HER2-ECD and TAP levels were compared before and 12 weeks after treatment. The patients were followed up for 3 years after treatment, and the 1-year, 2-year and 3-year survival rates were compared between the two groups. Results:After 12 weeks of treatment, the disease control rate of the observation group was higher than that of the control group, with statistically significant difference ( P<0.05); during the treatment, the incidence of gastrointestinal reaction, neutropenia, thrombocytopenia and abnormal liver function of the observation group was lower than that of the control group, with statistically significant difference ( P<0.05); after 12 weeks of treatment, the serum CD8 + level of the observation group was lower than that of the control group, and the serum CD4 + , CD4 + /CD8 + level was higher than that of the control group, with statistically significant difference ( P<0.05); after 12 weeks of treatment, the serum levels of HER2-ECD and TAP in the observation group were lower than those in the control group, with statistically significant difference ( P<0.05); the 3-year survival rate in the observation group was higher than that in the control group, with statistically significant difference ( P<0.05). Conclusions:Huaier granules combined with TEC neoadjuvant chemotherapy in patients with advanced breast cancer can reduce serum HER2-ECD, TAP levels, which can enhance the immune function of the body, reduce the toxic and side effects, improve the long-term survival rate, and have a significant effect.

Objective To explore the efficacy of fast-track surgery (FTS) combined with standard rehabilitation program (HSS) in elderly patients undergoing total hip arthroplasty (THA).Methods Ninety elderly patients with femoral neck fracture were randomly assigned to receive either FZS plus HSS Tehabilitation program (experimental group,n =45) or HSS rehabilitation program (control group,n =45) after THA from December 2013 to December 2014 in our hospital.The experimental group had 23 men and 22 women,with an average age of 68.2 ± 3.7 years.The control group had 22 men and 23 women,with an average age of 70.6 ± 4.1 years.Harris score and visual analogue scale (VAS) were used to assess the hip joint function before operation,4,8 and 14 weeks after operation.The complications were compared between the 2 groups at 14 weeks after operation.Results All the patients completed a 14-week follow-up.There were no significant differences in Harris and VAS scores at pre-operation between the 2 groups (P ＞ 0.05).At 4,8 and 14 weeks after operation,the Harris scores in the experimental group (67.2 ±3.5,88.3 ±2.5and 92.5±3.3) were significantly higher than those in the control group (52.5±7.8,65.8±4.9 and 72.2±4.9) and the VAS scores in the experimental group (3.4±0.8,2.2±0.8 and 1.3±0.5) were significantly lower than those in the control group (5.6 ±0.9,4.2 ±0.8 and 2.9 ±0.8) (P ＞ 0.05).There were no complications in the experiment group while there were 14 complications (31.1％) in the control group,showing a significant difference (P ＜ 0.05).Conclusion FTS combined with HSS standardized rehabilitation can effectively reduce the incidence of complications and accelerate the functional recovery of hip joint in elderly patients after THA.

Objective The purpose of this study was to establish a rat model of thromboembolism for the study of hemorrhag -ic transformation after intravenous thrombolysis with the recombinant tissue plasminogen activator ( rtPA) . Methods Sixty Sprague-Dawley rats were randomly divided into a sham operation , a cerebral embolism, and an rtPA group.Thrombus was prepared in vitro with the rat femoral artery blood and injected into the internal carotid artery of the rats in the cerebral embolism and rtPA groups to es -tablish a model of embolic focal cerebral ischemia , while the animals of the sham operation group injected with BSA .Five hours later , the rats in the rtPA group received rtPA and those in the cerebral embol-ism and sham operation groups the injection of isotonic saline solu-tion.At 24 hours after embolus injection , the neurological deficit score was obtained .The rats were sacrificed after cardiac perfusion and their brains removed for triphenyltetrazolium chloride staining , assessment of the infarct volume and cerebral edema , and calculation of the hemorrhage volume by spectrophotometric hemoglobin assay . Results The hemorrhage volume was significantly higher in the rtPA than in the cerebral embolism group ([17.55 ±2.20] μL vs [3.82 ±0.86] μL, P<0.01), but there were no statistically significant differences between the two groups in the infarct volume ([29.29 ±4.204] %vs [27.89 ±3.91] %, P=0.810), cerebral edema ([12.43 ±1.66] % vs [7.13 ±2.04] %,P=0.063 2), and neurological deficit score (3.35 ±0.27 vs 2.80 ±0.28, P=0.174). Conclusion The rat model of thromboembolism, with a high stability and reproducibility , can be used for the pathogenesis-related studies of hemorrhagic transformation after thromboly-sis with rtPA.
