BACKGROUND:At present, scholars general y believe that the physical and chemical properties of titanium mesh are fine as easy plastic, easy cutting, good corrosion resistance and wear resistance, non-magnetic, less effect on CT or MRI results, good histocompatibility and resistance to stress. The titanium mesh is regarded as an ideal material for cranioplasty. ＜br> OBJECTIVE:To explore the clinical feasibility of primary reconstruction of comminuted and open skul fracture with titanium mesh. ＜br> METHODS:Sixty-two cases of comminuted and open skul fracture were analyzed retrospectively, including 49 males and 13 females, aged 7-69 years. Among these 62 patients, 30 patients underwent debridement and then after 6-12 months, they received titanium mesh reconstruction, serving as control group. Another 32 cases underwent debridement and titanium mesh reconstruction in the same time as observation group. Al the cases were fol owed-up for 1-2 years to observe wound healing, complications and hospitalization cost. ＜br> RESULTS AND CONCLUSION:During the fol ow-up, no wound infection and intracranial infection occurred in the two groups. The incidence of intracranial hematoma, epilepsy, and other complications was higher in the control group than the observation group (P＜0.05), and the hospitalization cost was also higher in the control group than the observation group (P＜0.05). These findings indicate that primary reconstruction with titanium mesh is feasible in the treatment of comminuted and open skul fracture and can significantly reduce the incidence of complications and hospitalization costs.

Objective To explore the clinical effect of periarticular knee fractures combined with anterolateral ligament (ALL) avulsion fracture.Methods From June 2014 to November 2015,13 patients with ALL avulsion fracture in periarticular knee fractures were fixed by the star plate,cannulated or screws suture anchor,including 9 male and 3 female with the mean age of 39.5 years (range from 28 to 51 years).6 patients were diagnosed distal femoral fracture,4 tibial plateau fracture,and 3 tibial intercondylar eminence avulsion fracture which all combined with ALL avulsion fracture.Postoperatively,all patients were treated with the adjustable knee brace for 3 months.Results All patients were followed up for 4-20 months,the mean follow-up time was 13.5 months.The average surgical time was 130 min (range from 90 to 210 min).In all 13 patients,ALL was found and identified.Bone union was obtained in all patients,and the bone union time was 11.4 weeks (10-12 weeks).7 cases were fixed with star plate,5 cases were fixed with hollow screw,and 1 case was fixed with anchor.All follow-up patients underwent anteroposterior and lateral X-rays.Pain,swelling and functional recovery of the knee joint were observed.Patients were assessed postoperatively with International Knee Documentation Committee (IKDC) score,Lysholm score,and Tegner activity scale to evaluate the clinical effect.At the last follow-up,all patients had full range of motion of the knee joint which from 0° to approximate 120°.The Lysholm,objective IKDC were 86.5 and 84.6 respectively.Among the 13 patients evaluated,9 patients were graded A,and 4 patients were graded B by subjective IKDC.The Tegner activity scale at the last follow-up was 6.7.Incision of poor healing in 1 case,and got healed after 32 d cleaning dressing.Conclusion This study confirmed the presence of the ALL.The fixation of ALL avulsion fracture in periarticular knee fractures can be an effective procedure at a minimum follow-up of 13.5 months.

Since epidemiologic studies have reported a modestly increased risk of oncogenesis associated with certain electromagnetic fields (EMF), popular media and scientists have raised concerns about possible health hazards of environmental exposure to EMF. Laboratory-based experiments have shown that a variety of biological responses were induced by EMF, although these results were controversial and conflicting. The non-thermal effects of low energy EMF,the possible interaction of EMF with biological system have become focus topics in the biolectromagnetic fields. This paper focuses on recent studies of static and extremely low frequency electromagnetic fields, especially the interactive mechanism between EMF and cellular membrane and protein kinase signal transduction pathways. The potential genetic toxicity and risk evaluation are also discussed. However, the existence of some positive findings and the limitations in the set of studies suggest a need for more work.

Objective To investigate the effect of pre-implanted anti-adhesion patch under laparoscopic approach in a Miles' operation on the incidence of parastomal hernia in elderly patients.Methods A total of 68 patients with low rectal cancer admitted into our general surgery department were enrolled in the study from January 2012 to January 2015.All patients received laparoscopic assisted Miles operation.According to whether or not the pre-implanted anti adhesion patch was used during the operation,the 68 cases were divided into pre-implanted patch group(n=38)and the non-implanted patch group(n=30).The operation states,postoperative complications,complications during follow-up and 3-year survival rate were compared between the two groups.Results The operation duration was longer in the pre-implanted patch group than in the non-implanted patch group[(235.7± 33.6)min vs.(94.3±28.9)min,t =5.36,P=0.000].The incidence of complications was lower in the pre implanted patch group than in the non-implanted patch group at 3 years after operation[10.5％ (4/38)vs.90.0％(27/30),x2 =42.69,P =0.000].The local recurrence rate,distant metastasis rate and 3-year overall survival rate had no significant difference between the two groups[23.7 ％ (9/38)vs.23.3％ (7/30),31.6％ (12/38) vs.33.3％ (10/30) and 71.1％ (27/38) vs.70.0％ (21/30)respectively,x2=0.06,0.02 and 0.01,P=0.800,0.878 and 0.925].Conclusions Pre-implanted anti-adhesion patch under laparoscopic approach can significantly reduce the incidence of parastomal hernia in elderly patients after a Miles' operation,which is worthy of promotion.

Objective To investigate the morphological characteristics of superior sagittal sinus (SSS) and bridging vein (BrV) with virtual reality (VR) technology and their clinical significances.Methods Forty-three patients with parasagittal meningioma (PSM group) and 21 patients with trigeminal neuralgia or hemifacial spasm who had no intracranial venous system diseases (normal group),admitted to our hospital from October 2011 to March 2013,were chosen.The morphological characteristics of SSS and parasagittal BrV of patients from the 2 groups were observed,which was finished in the VR workstation.The number and diameter differences of cortical veins between the 2 groups,and bilatelal side and the first,middle and third 1/3 of SSS of normal group were analyzed.Results Among the patients from the 2 groups,4 having SSS extremity with morphological variation were observed firstly.The direction of BrV entering the SSS mainly was retrograde,which concentrated in the middle and third 1/3 of SSS.There were many directions of BrV entering the SSS in the first 1/3 of SSS,and the direction mostly was perpendicular.In normal group,there were no statistical differences of number and diameter in the bilatelal cortical veins (P＞0.05); in the first,middle and third 1/3 of SSS,there was statistical difference of cortical veins number (P＜0.05),but no difference of diameter (P＞0.05).The number and diameter of cortical veins of PSM group were under the normal group,with statistically significant difference (P＜0.05).With the growth of PSM,violations of SSS and cortical venous gradually aggravated,affecting venous return,which resulted in increase number and complication of collateral veins.Conclusions There is certain variability of SSS and related BrV.The direction of BrV entering the SSS may be associated with intracranial venous system hemodynamic.It is clear and three-dimensional to observe SSS and cortical veins in the help of VR,and to analyze the venous circulation changes caused by PSM.

Objective:To investigate the effect of glabridin on neutrophil extracellular traps (NETs) formation and pyroptosis in rats with sepsis-induced lung injury.Methods:Twenty-four male Wistar rats were divided into three groups according to the random number table method. The sepsis group was established by cecal ligation and puncture (CLP). The Glabridin group underwent CLP and glabridin gavage (30 mg/kg)(CLP+GLA). The sham operation group underwent cecal exploration, and only the abdomen was closed after cecal turning(Sham). After 12 hours, plasma、alveolar lavage fluid and lung tissue samples were taken for detection . Then, protein content of the alveolar lavage fluid was determined; The wet/dry weight(W/D) ratio of the lung tissue was determined; The pathological changes in lung tissue were observed after hematoxylin-eosin (HE) staining. The levels of NETs marker MPO-DNA complex and related inflammatory factors IL-18 and IL-1β in plasma were detected by enzyme-linked immunosorbent assay. The changes of Caspase-1and Cleaved-caspase-1 protein in lung tissue were detected by Western blot.Results:The total protein concentration of alveolar lavage fluid was significantly higher in the sepsis group compared with the Sham group ( P<0.01), and it decreased in the glabridin group compared with the sepsis group ( P<0. 05). Significant aggravation of pulmonary edema in the sepsis group, and the glabridin group reduced pulmonary edema compared with the sepsis group.The pathological results of lung tissue under the light microscope showed: The structure of lung tissue in the Sham group was normal, and the alveoli were clear; In the sepsis group, the alveolar wall was thickened widely and inflammatory cells infiltrated obviously; Compared with the sepsis group, the lung tissue injury was significantly reduced in the light licorice group. The enzyme-linked immunosorbent assay results showed that the levels of NETs marker MPO-DNA complex and inflammatory factors IL-18 and IL-1β in the plasma of the sepsis group were significantly higher than those in the Sham group ( P<0.001). The levels of NETs marker MPO-DNA complex and inflammatory factors IL-18 and IL-1β in the glabridin group were significantly lower than those in the sepsis group (MPO-DNA: P<0. 01; IL-18、IL-1β: P<0.05) . Western blot Technical results showed that the expression of Caspase-1 and Cleaved-caspase-1 protein positive signal was significantly enhanced in the lung tissue of the rats in the sepsis group compared with the Sham group; the distribution of Caspase-1 positive cells in the lung tissue of the sepsis + glabridin group was similar to that of the Sham group, and the expression of Cleaved-caspase-1 positive signal was higher than that of the Sham group. Conclusions:Glabridin can effectively reduce lung inflammation and play a protective role in lung injury in septic rats by inhibiting NETs production and pyroptosis.
