ObjectiveTo identify the relevant factors of expansion of contusive cerebral hemorrhage following unilateral decompressive craniectomy in patients with severe craniocerebral injury and discuss their relation with prognosis.MethodsA total of 161 consecutive patients with craniocerebral injury undergoing unilateral decompressive craniectomy were prospectively studied.Their initial cranial CT data (data after injury,data before operation,and data after first operation) were recorded.Mortality or Glasgow Outcome Scale (GOS) at 6 months after injury was used as the criteria for evaluation of prognosis.ResultsThe volume of increased contusive cerebral hemorrhage among the patients after craniectomy was (18.66 ± 22.69) ml.The Rotterdam score of their initial cranial CT after injury was significantly associated with the occurrence or not of expanded contusive cerebral hemorrhage following decompressive craniectomy and the expanded hematoma volume.The expanded volume of contusive cerebral hemorrhage ( ＞ 20 ml) after craniectomy showed significant relevance to mortality and poor prognosis six months later.The magnitude of external cerebral herniation ( ECH ) on the initial post-operative CT was associated with the prognosis. ConclusionsThe severity of patients with craniocerebral injury manifested by the initial cranial CT may predict the risk of expansion of contusive cerebral hemorrhage following decompressive craniectomy.The expansion volume of contusive cerebral hemorrhage and ECH are correlated with mortality and poor prognosis.

The changes of immunoreactive TRH (TRH-ir) in cerebrospinal fluid (CSF) and plasma before and after acute traumatic head injury were determined with radioimmunoassay (RIA) on a feline model of acute experimental head trauma. The results showed that the concentrations of TRH-ir in experimental animals pre- and 2, 4, and 6h post-injury were 119.48?51.77, 460.71 ?178.72, 377.27? 139.33, and 280.17?110.46pmol/L in CSF, and 122.58?28.87,1158.89?163.18, 909.69?160.55, and 545.38?132.80pmol/L in plasma, respectively, while those in control animals measured at the corresponding time were 112.22?53.42, 105.36?49.64, 100.63?52.89, and 104.52?52.42pmol/L in CSF, and 113.57 ?25.79, 107.32?26.60, 119.84?31.53, and 117.21?28.95pmol/L in plasma, respectively. The contents of TRH-ir in CSF and plasma in the experimental group after traumatic head injury were significantly higher than those, in the control group (P

The fetal spleen cells were transplanted following the injection of S180 carcinosarcoma into the muscle,abdominal cavity,peripheral veins and portal vein in mice.The size inhibitory rate of the transplanted tumor and natural killer activity were evaluated 30 and 60 days after the injection.It was found that the growth of transplanted tumor was dramatically inhibited and natural killer activity was increased 30 days after the transplantation.But 60 days after the transplantation only portal venous transplanted tumor showed a satisfactory function of inhibiting tumor growth and natural killer activity maintained at a high level.These results indicated that portal vein was the best approach for the spleen cell transplantation

To improve the AIDS's knowledge level and intervention ability of peer lecturers in college, from the accumulation idea and activity type of experience value on Moso Teach, the author carried out systematic resource construction around the course design principles and objectives, at the same time one quantitative scoring system including learning degree and sharing degree was constructed. Through voluntary enrollment and selection among the students, the first group of peer lecturer training on AIDS prevention were set up, and 28 students were collected to experience the "mixed" application of the course. After the evaluation, it was found that there were positive functions in promoting the ability of AIDS prevention in the peer lecturer training course based on experience value of Moso Teach as the driving force and quantification. According to the problems exposed in the construction, the author put forward improvement strategies from the aspects of scoring system, off-line activities and resource optimization.

To promote the combination of basic medical education and clinic medical edu-cation,we carried out the exploration on stomatological human anatomy course linked up with imi-tative oral clinic teaching.The evaluation to the effect of the teaching methods showed that it could induce the stomatological students to apply the theory to the clinic practice,consolidate their mas-tery and understanding of stomatological human anatomy and train their ability to acquire knowledge actively.

0.05). The 1,3 and 5-year regional control and survival rates in both groups were concordant, demonstrating that the prognosis of these two groups was similar. The 5-year survival rate in pre-operative radiotherapy group was 37%. The results of retrospective analysis by Log-rank and Cox proportional regression methods demonstrated that whether the tumor resected or not were the major factors affecting pre-operative radiotherapy effect.

Objective To investigate the safety and efficacy of placement of self expandable metallic stent within right atrium and inferior vena cava (ICV) in patients with malignant ICV obstruction involving right atrium. Methods There were 5 male patients with advanced hepatocellular carcinoma, aged from 42 to 65 years (mean 56 3 years). The malignancies invaded right atrium and ICV simultaneously, and caused obstruction of ICV. These patients presented symptoms and signs of obstruction of ICV such as hepatomegaly, ascites, edema of lower extremities. “Z” type stainless steel stents (7 5～10.0 cm in length and 2 5 cm in diameter) were selected for these patients. Part (1.0～3.0 cm in length ) of stent was placed in right atrium and the rest was in ICV. Results All of stents were placed successfully and obstructed ICV reopened. The symptoms of obstruction of ICV relieved or disappeared. There were no recurrence of symptoms of obstruction of ICV and any cardiac complication related to placement of stents in follow up period (67～188 days). Conclusion Placement of self expandable metallic stent within right atrium and ICV in treatment of patients with malignant ICV obstruction involving right atrium is one of the safe and effective methods.

BACKGROUND:Studies suggested that blood loss was great during total knee arthroplasty, even blood transfusion was needed. Application of the tourniquet wil destroy the coagulation system, and is not conducive to hemostasis after replacement. Recently, tranexamic acid has been extensively used to reduce blood loss during total knee arthroplasty, because of low price, simple administration pathway, and effective effects on hemostasis. OBJECTIVE:To summarize the application and safety of tranexamic acid in total knee arthroplasty. METHODS:The first author retrieved PubMed and Chinese Journal Ful Text Database for articles from inception to October 2015. The key words were tranexamic acid, total knee arthroplasty, hemorrhage. More than 200 articles were retrieved, and finaly 50 articles met the inclusion criteria. RESULTS AND CONCLUSION:Tranexamic acid is a fibrinolytic inhibitor, can reversibly block the binding of plasminogen to fibrin, effectively inhibit fibrinolysis, and reduce hemorrhage after total knee arthroplasty. Nevertheless, there were significant differences in the use, dose and effect of tranexamic acid on hemostasis among different studies. Tranexamic acid was an effective drug for hemostasis during total knee arthroplasty. During total knee arthroplasty, tranexamic acid had been used to reduce dominant blood loss and hidden blood loss after arthroplasty, and could not increase the risk for venous thrombosis of lower limb. Currently, the timing of use, dosage, route of administration, and possible complications of tranexamic acid remain controversial.
