Objective To explore the method and the clinical effects of surgical treatment for severe hedge brain injury at frontotemporal bottom. Methods 96 patients with severe hedge brain injury at frontotemporal bottom were scored by GOS before surgery. Then unilateral or bilateral craniotomy was carried out,via a large flap incision in the site of frontotemporal and parietal hair,and the blood clots within the surgical fieldand the inactivation brain tissue having been fell off were removed, and the contusion lesions of brain bottom were exposed, and the inactivation brain tissue was cleared. If the brain injury was serious ,the removal of frontal pole and temporal pole should be proper. Discretion to The removing or replacing the bone flap should be based on consideration of the circumstances. Six nonths or one year after injury,96 patients were scored by GOS again. Results There were 17 cases of grade Ⅰ(17.71%) ,11 cases of gradeⅡ (11.46%),13 cases of gradeⅢ (13.54%),21 cases of grade Ⅳ(21.86%),34 cases of grade Ⅴ (35.42%) in 96 patients. Conclusion Early surgical treatment of severe hedge brain injury at frontotemporal bottom could improve the cure rate and reduce the rate of disability.

Objective To evaluate the surgical results for patients with lower-extremity arteriosclerotic occlusive disease. Methods We performed a respective analysis of 358 patients who underwent various consecutive surgical treatments including open artery reconstruction and intervention in our hospital between 2002 and 2007.Results In this study,358 patients(mean age 66 ± 10;293 male,65female)experienced a total of 413 surgical interventions including traditional bypass,interventional surgery and amputation.Postoperatively 310 patients(86.8%)were followed up from 6 months to 64 months.The 1-year,2-year and 3-year primary patency rates of iliac balloon angioplasty and stent placement were significantly higher than that of femoropopliteal balloon angioplasty and stent placement(P＜0.01),but not higher than that of aortoiliac or aortofemoral bypass(all P＞0.05).The 2-year and 3-year primary patency rates of femoropopliteal bypass above knee were significantly higher than that of femoropopliteal bypass below knee(P＜0.01),but that was not the case in 1-year group.There is no statistical difference in 1-year primary patency rates between femoropopliteal balloon angioplasty and distal popliteal balloon angioplasty (P＞0.05).Amputation rate was 8.7%(37/358).Perioperative mortality was 3.9%(14/358).Mortality during follow-up period was 6.4%(23/358).Conclusion A satisfactory result can be obtained in most patients with the lower-extremity arteriosclerotic occlusive disease by using the appropriate surgical treatment.

Objective To explore the relationship between the membranous tissue(MT)and organized thrombus(OT)in membranous obstruction of the inferior vena cava(MOVC),we investigated the related cytokines expression in the membranous tissues in MOVC as well as venous organized thrombi. Methods Using immunohistochemical method the expression of TGFβR,PDGFR,ET-1,FⅧ-rAg, ferritin and α1-antitrypsin were observed in the membranous tissues in 11 cases with MOVC and organized thrombi in 8 cases with deep venous thrombosis(DVT). Results Expression rates of TGFβR,PDGFR,ET-1,FⅧ-rAg, and ferritin in membranous tissues in 11 cases with MOVC and organized thrombi in 8 cases with DVT were as follows: TGFβR:MT 72.3%,OT 50%(P＞0.05);PDGFR:MT 45.5%,OT 100%(P＜0.05＝;ET-1:MT 100%,OT 0(P＜0.05＝;FⅧ-rAg: MT 90.9%,OT 12.5%(P＜0.05＝;ferritin: MT 72.3%,OT 100%(P＞0.05).α1-antitrypasin was not detected in either membranous tissues of MOVC or organized thrombi of DVT. Conclusions ThrovIgh the investigation of the related cytokines expression, it is possible that membranous tissue formation in MOVC is related to the organized thrombus.

Objective To observe the effects of eluting stents coated with arsenic trioxide(As2O3)and suspended in poly-L-lactic acid(PLLA)on expression of monocyte chemoattractant protein-1 (MCP-1)and interleukin-6(IL-6)and to assess the effects of As2O3 eluting stents on local inflammatory reaction in injured coronary arteries in pigs. Methods Bare metal stents,rapamycin eluting stents and As2O3-eluting stents were randomly and double-blindly implanted into the anterior descending branches,circumflex branches and right coronary arteries in eight pigs.Animals were sacrificed and coronary arteries were isolated 7 days after stents implantation.The expression levels of protein and mRNA of MCP-1 and IL-6 were determined by Western blot analysis and reverse transcription polymerase chain reaction(RT-PCR),and the inflammatory cell infiltration was observed by HE staining and immunohistochemistry. Results Compared to bare metal stents,As2O3-eluting stents and rapamycin-eluting stents identically and markedly inhibited the protein expression level of MCP-1(0.421±0.055 and 0.406±0.042 vs.0.857±0.053,P＜0.01)and IL-6(0.151±0.032 and 0.146±0.051 vs.0.551±0.032,P＜0.01)and correspondingly lowered the mRNA expression level of MCP-1(0.338±0.047 and 0.327±0.051 vs.0.724±0.027,P＜0.01)and IL-6(0.531±0.052 and 0.523±0.061 vs.1.015±0.041,P＜0.01),and significantly reduced the inflammatory cell infiltration of injured coronary arteries in pigs. Conclusions As2O3-eluting stents can effectively inhibit the expressions of MCp-1 and IL-6 and reduce the inflammatory cell infiltration of injured coronary arteries in pigs.

Objective:To investigate the clinical effect and short-term and long-term effect of total hip replacement (THA) and hemiarthroplasty of hip (HA) in elderly patients with femoral neck fracture (FNF).Methods:59 elderly patients with FNF in South District of Guang′anmen Hospital, Chinese Academy of Traditional Chinese Medicine from March 2017 to January 2019 were retrospectively analyzed. The observation group ( n=29) was treated with THA; The control group ( n=30) was treated with HA. The operation related indexes, short-term and long-term clinical effect (average follow-up of 24.1 months), hip function improvement, pain and complications were compared between the two groups. Short term and long-term clinical effects: the short-term and long-term clinical effects of the two groups were observed by the Harris Hip Score (HHS) of the first month, the third month, the sixth month, the ninth month and the first year after operation. Results:Both THA and HA were effective on elderly FNF, but the effective rate of THA (96.6%) was significantly higher than that of HA (90.0%), with statistically significant difference ( P<0.05); in terms of operation related indicators, compared with the control group, the observation group had longer operation time [ (104.46±3.24)min vs (84.34±3.64)min], more amount of bleeding [(296.64±15.16)ml vs (281.44±12.16)ml], lower postoperative drainage volume [(101.24±4.15)ml vs (74.56±3.24)ml], while the functional recovery of the observation group was better than the control group by HHS ( P<0.05); the postoperative complications and HHS score of observation group were significantly lower than the control group ( P<0.05). Conclusions:THA has the advantages of low complication, fast functional recovery and better effect. The clinical decision should be based on the patient′s physical condition. THA should be used for elderly patients with good basic condition, good surgical tolerance and more daily activities. HA should be used for elderly patients with poor basic condition, low surgical tolerance and less daily activities.

The mammalian central nervous system (CNS) is considered an immune privileged system as it is separated from the periphery by the blood brain barrier (BBB). Yet, immune functions have been postulated to heavily influence the functional state of the CNS, especially after injury or during neurodegeneration. There is controversy regarding whether adaptive immune responses are beneficial or detrimental to CNS injury repair. In this study, we utilized immunocompromised SCID mice and subjected them to spinal cord injury (SCI). We analyzed motor function, electrophysiology, histochemistry, and performed unbiased RNA-sequencing. SCID mice displayed improved CNS functional recovery compared to WT mice after SCI. Weighted gene-coexpression network analysis (WGCNA) of spinal cord transcriptomes revealed that SCID mice had reduced expression of immune function-related genes and heightened expression of neural transmission-related genes after SCI, which was confirmed by immunohistochemical analysis and was consistent with better functional recovery. Transcriptomic analyses also indicated heightened expression of neurotransmission-related genes before injury in SCID mice, suggesting that a steady state of immune-deficiency potentially led to CNS hyper-connectivity. Consequently, SCID mice without injury demonstrated worse performance in Morris water maze test. Taken together, not only reduced inflammation after injury but also dampened steady-state immune function without injury heightened the neurotransmission program, resulting in better or worse behavioral outcomes respectively. This study revealed the intricate relationship between immune and nervous systems, raising the possibility for therapeutic manipulation of neural function via immune modulation.
