Objective To investigate effects of hyperbaric oxygen (HBO) therapy on C-reactive protein (CRP) and tumor necrosis factor-α (TNF-α) levels in patients with moderate or severe traumatic brain injury (TBI)and to analyze its therapeutic efficacy. Methods One hundred and eight patients with moderate or severe TBI were randomly divided into a control group (54 cases) and an HBO adjunctive therapy group (HBO group, 54 cases).Both groups received essential neurosurgical treatment and conventional drug treatment, and the HBO group was given one session of HBO therapy in addition. Serum CRP and TNF-α were detected, and the scores on the Glasgow coma scale (GCS) were measured before and after treatment. CRP was detected by turbidimetric immunoassay and TNF-α using ELISA. Glasgow outcome scale (GOS) scores were evaluated in a follow-up 6 months after injury. Results Average CRP, TNF-α and GCS measurements showed no statistically significant difference between the groups before treatment. After treatment, CRP and TNF-α were significantly lower and GCS scores significantly better in both groups, but patients in the HBO group were, on average, significantly better than the controls on all three measures.Six months later, GOS evaluation gave a significantly larger number of patients with a better prognosis in the HBO group compared with the controls. Conclusion HBO therapy can significantly decrease serum CRP and TNF-α after severe TBI, thus enhancing therapeutic efficacy.

Objective To explore the clinical outcomes of treating unstable intertrochanteric fractures with proximal femoral locking plate (PFLP) in the elderly patients.Methods From January 2010 to June 2015,380 elderly patients with unstable intertrochanteric fracture were treated with PFLP and successfully followed up at our department.They were 171 men and 209 women,from 60 to 89 years of age (average,68.7 years).By AO classification,there were 58 cases of AO31-A2.2,87 ones of 31-A2.3,130 ones of 31-A3.1,63 ones of 31-A3.2,and 42 ones of 31-A3.3.Operation time,incision length,length of hospital stay,fracture healing time,postoperative complications and hip joint Harris scores were recorded.Results This cohort was followed up for an average of 13.3 months (range,from 8 to 21 months).Their operation time averaged 53.2 min,X-ray exposure 12.2 times,intraoperative blood loss 92.7 mL,incision length 12.6 cm,postoperative drainage volume 54.7 mL,and length of hospital stay 9.2 days.Pulmonary infection was observed in 3 cases,fixation loosening in 8,fixation breakage in 2,hip varus in 9,and fracture nonunion in 4,yielding a total complication rate of 6.8％ (26/380).No operative incision infection was observed.The average fracture healing time was 11.8 weeks (range,from 7 to 48 weeks) after operation.The average Harris score one year postoperation for the 380 patients was 86.3 ± 6.1,significantly higher than the preoperative value (43.6±4.4) (P ＜0.05).There were 96 excellent,231 good,42 fair and 11 poor cases,giving an excellent to good rate of 86.1％.Conclusion Since PFLP has advantages of limited invasion,blood loss and complications,a high rate of fracture healing,and good functional recovery of the hip,it may be a good treatment for unstable intertrochanteric fractures in the elderly patients.

Objective To explore the efficacy of proximal femur locking plate(PFLP) for the treatment of unstable femoral intertrochanteric fractures in elderly patients.Methods Data of 120 cases of patients with unstable femoral intertrochanteric fractures who were treated by PFLP were retrospectively analyzed.There were 56 males and 64 were females,aging from 62 to 78 year-old (average,69.4 year-old).85 cases were left hip,and 35 cases right hip.According to AO fracture classification,there were 12 cases of A2.2,23 A2.3,34 A3.1,29 A3.2,and 22 A3.3.According to Evans intertrochanteric fractures classification:there were 93 cases of type Ⅲ,19 type Ⅳ,and 8 type Ⅴ.Operation time,length of hospital stay,fracture healing time,postoperative complications and hip joint Harris scores were recorded.Results All patients were followed up for 8-14 months (average,12.4 months).Their operating time were 51-80 min (average,63.1 min);X-ray exposure were 8-15 times (average,11.6 times);intraoperative blood loss were 70-120 ml (average,92.7 ml);postoperative drainage volume were 50-100 ml (average,61.7 ml),and length of hospital stay were 7-14 d (average,10.2 days).The healing time ranged from 12 to 32 weeks (20.4 weeks average).14 cases had delayed union,and healing time was 8-10 months.In addition,4 cases had deep vein thrombosis (after thrombolysis therapy the vein was recanalized);2 had internal fixation broken,who were then treated with PFNA Ⅱ,and bone healed after 6 months;5 had hip varus,who were then treated via hip replacement,and no hip prosthesis fracture were found.No other complications occurred in the remaining patients.At the latest follow-up,according to Harris hip score:there were 38 cases with excellent results,71 good,9 fair,and 2 poor,and the rate of excellent and good was 90.8％ (109/120).Conclusion PFLP for the treatment of unstable femoral intertrochanteric fractures has advantages of less invasion,less complication,reliable fixation and high fracture healing rate,thus it is suitable for unstable intertrochanteric fractures in elderly patients.

Antiangiogenic therapy can generate a "normalization window" for tumor vasculature. This normalization process prunes immature vessels and improves the integrity and function of the remaining vasculature by enhancing the perivascular cell and basement membrane coverage in tumor, therefor creates a window of opportunity for improved sensitivity to ionizing radiation and the delivery of chemotherapeutic drugs. It provides a rational basis for the combination therapy of traditional Chinese drugs with radiation and perhaps other forms of chemotherapy. Antiangiogenic therapy with the traditional Chinese drug interfering in the the mechanisms of the normalization window in humans maybe harness a new approach to improve the sensitivity of tumors to radio- and chemotherapy.

Objective To investigate the effects of hyperbaric oxygen (HBO) therapy on interleukin-1 β( IL-1 β) and interleukin-6 ( IL-6 ) levels in patients with moderate or severe traumatic brain injury ( TBI ) and to analyze its therapeutic efficacy.MethodsOne hundred and fifty-six patients with moderate or severe TBI were randomly divided into a control group and an HBO adjunctive therapy group with 78 cases in each.The control group received essential neurosurgical treatment and conventional drug treatment,and the HBO group was given one HBO therapy session in addition.IL-1 β and IL-6 were quantitatively determined using sandwich ELISA,and the patients'scores on the Glasgow coma scale (GCS) were measured before and after treatment.The Glasgow outcome scale (GOS) was used to evaluate in a follow-up 6 months after injury.ResultsThe average IL-1 β and IL-6 levels of the two groups and their average GCS scores were not significantly different before treatment.After treatment,IL-1 βand IL-6 levels decreased significantly and GCS scores increased significantly in both groups,but there were significant inter-group differences in all three measures.Six months after injury the GOS evaluation indicated that significantly more patients had better outcomes in the HBO group than in the control group. Conclusion Conventional treatment combined with HBO therapy can promote neurofunction recovery in TBI patients.The mechanism may be related to down-regulation of serum IL-1 β and IL-6.

Objective To analyze the related factors of femoral head necrosis after internal fixation operation of femoral neck fracture.Methods Clinical data of 524 patients with femoral neck fracture who underwent internal fixation surgery between January 2012 and January 2015 were retrospectively analyzed.Taking the femoral head necrosis as an observable indicator,the clinical data of postoperative femoral head necrosis and those other patients who were treated at the same period were compared.Whether the clinical factors (gender,age,surgical reduction type,fracture type,quality of reduction,post-injury operation time,loading time after operation,and whether to withdraw internal fixation) were in correlation with postoperative femoral head necrosis was analyzed by univariate analysis.Then the statistically significant indicators were integrated into logistic regression analysis to determine the related factors of femoral head necrosis.Results According to inclusion and exclusion criteria,the study group consisted of 212 cases,including 94 males and 118 females;the follow-up time was 2-5 years,and the average follow-up time was 3.6±1.6 years.There were 46 cases with femoral head necrosis and 166 cases without femoral head necrosis after operation.The rate of femoral head necrosis was 21.7％ (46/212).The femoral head necrosis group included 46 cases with 21 males and 25 females;20 cases below 60 years old and 26 cases above 60 years old;17 cases using open reduction and 29 cases using closed reduction;6 cases belong to type Ⅰ/Ⅱ and 40 cases belong to type Ⅲ/Ⅳ according to Garden classification;16 cases got satisfactory reduction while 30 cases with unsatisfactory reduction;30 cases below 48 h and 16 cases above 48 h on post-injury operation time;17 cases below 3 months and 29 cases above 3 months on post-operation loading time;22 cases with internal fixation removal and 24 cases without internal fixation removal.The femoral head without necrosis group included 166 cases with 73 males and 93 females;84 cases below 60 years old and 82 cases above 60 years old;69 cases using open reduction and 98 cases using closed reduction;120 cases belong to type Ⅰ/Ⅱ and 46 cases belong to type Ⅲ/Ⅳ according to Garden classification;160 cases got satisfactory reduction while 6 cases with unsatisfactory reduction;119 cases below 48 h and 47 cases above 48 h on post-injury operation time;70 cases below 3 months and 96 cases above 3 months on post-operation loading time;74 cases with internal fixation removal and 92 cases without internal fixation removal.Univariate x2 analysis suggested that fracture type and quality of reduction were associated with postoperative femoral head necrosis.Other clinical factors (gender,age,surgical reduction type,post-injury operation time,loading time after operation and whether to remove internal fixation or not) were not associated with postoperative femoral head necrosis.The multivariate Logistic regression analysis showed fracture type and quality of reduction were significantly related to postoperative femoral head necrosis.Conclusion Femoral head necrosis after internal fixation operation of femoral neck fracture is affected by many factors.The fracture type and quality of reduction are important factors affecting femoral head necrosis after internal fixation operation of femoral neck fracture.

Objective To investigate the advantage and application prospect of 3D printing technology in assisting surgery for complex tibial plateau fractures.Methods The complete clinical data of 41 patients (48 knees) were retrospectively analyzed.And these patients were divided into two groups as 3D printing assisted operation group and traditional operation group,according to whether 3D printing technology was applied.Study was carried out to compare the clinical efficacy of surgery assisted by 3D printing technology and traditional surgery in the treatment of complex tibial plateau fractures.The 3D printing assisted operation group included 18 patients (22 knees,12 males and 6 females),aging from 16 to 68 (mean age 45.5±7.2),and there were 12 cases of Schatzker Ⅴ and 10 Ⅵ.The traditional operation group included 23 patients (26 knees,15 males and 8 females),aging from 19 to 69 (mean age,46.2±6.8),and there were 14 cases of Schatzker Ⅴ and 12 Ⅵ.The operation time,intraoperative blood loss,the Rasmussen score and hospital for special surgery knee score (HSS) at 6 weeks post-operation were analyzed and the difference between the two groups was tested.Results All those patients were followed up for 7 to 20 months (mean 15 months).For 3D printing assisted operation group,the mean operation time was 81.4±6.3 min for Schatzker Ⅴ and 90.6± 15.4 min for Schatzker Ⅵ;the mean intraoperative blood loss was 200.4±72.3 ml for Schatzker Ⅴ and 280.6±101.6 ml for Schatzker Ⅵ;the result of 6-week Rasmussen score was 14 excellent,6 good and 2 fair (excellent and good rate 90.9％);the result of 6-week HSS score was 15 excellent,5 good and 2 fair (excellent and good rate 90.9％).Then for traditional operation group,the mean operation time was 100.4± 15.3 min for Schatzker Ⅴ and 111.5±20.2 min for Schatzker Ⅵ;the mean intraoperative blood loss was 450.4±173.3 ml for Schatzker Ⅴ and 500.5±247.2 ml for Schatzker Ⅵ;the result of 6-week Rasmussen score was 14 excellent,8 good,2 fair and 2 bad (excellent and good rate 84.6％);the result of 6-week HSS score was 13 excellent,8 good,2 fair and 3 bad (excellent and good rate 80.8％).The difference in operation time,intraoperative blood loss had statistical significance between the two groups;but the difference in 6-month post-operation Rasmussen score and HSS score had no statistical significance.Conclusion Compared with traditional surgery,3D printing technology assisted surgery for complex tibial plateau fracture possesses advantage such as shortened operation time,reduced intraoperative blood loss;but there's no evidence for improved knee function at 6 weeks post-operation.

Objective To investigate the intervention effects ofYinao Jieyu Prescription on the behaviors and damages in hippocampal CA1 area of the rats with post-stroke depression (PSD).Methods Totally 168 SPF male SD rats were randomly divided into normal group, sham-operation group, stroke group, PSD group, Western medicine group and TCM group. There were 24 rats in the normal group and sham-operation group, and 30 rats in the other groups. Rats in the normal group received no intervention. Rats in the sham-operation group received no suture. Rats in the stroke group were given middle cerebral artery occlusion operation and normally fed after operation. Rats in the PSD group, Western medicinal group and TCM group were made into PSD models by chronic immobilization stress for one week and individual battery to the end. At the inception of modeling, Western medicine group received fluoxetine hydrochloride for gavage; TCM group receivedYinao Jieyu Prescription for gavage; other groups received distilled water for gavage, once a day. At the end of week 2, 4, and 8, the morphology of the hippocampal CA1 area in each rat was observed by microscope after HE stained.Results Except for the week 2, at the same time point, the behavior scores of the rats in the TCM group were higher than those in the PSD group. At the same time point, the CA1 region of the hippocampus in the TCM group was more complete than the PSD group, and the cells were arranged neatly and in normal morphology.ConclusionYinao JieyuPrescription can improve the symptoms of PSD rats, and has protective effects on hippocampal CA1 area.
