There were significant difference between ITP group and control group(P

Medical care on the battlefield is the core and basis of echelons of care.This review summarizes the background and characteristics of medical care units on the battlefield from the birth and growth of mobile army surgical hospitals before being replaced by forward surgical teams and combat support hospitals, since the United States Armed Forces began to lead the world military revolution during and after the World WarⅡ.Quick adaptation to the combat envi-ronment and the combat modes is the main reason that medical care units on the battlefield are adjusted continuously.This paper may provide some ideas for the development of our medical care units on the battlefield in the future.

Objective To investigate the characteristics and treatment effects in patients with spinal fractures associated with dural tears.Methods A retrospective analysis was made on 185 patients with spinal fractures presenting to hospital from February 2013 to February 2015.There were 103 males and 82 females,aged 17-73 years (mean,58 years).Causes of injury were high falls in 72 patients,traffic collisions in 58,hitting by heavy objects in 41,ground-level falls in 12,and collision events in two.Cervical spine fractures were seen in 65 patients,thoracic vertebra fractures in 51,and lumbosacral vertebral fractures 69.Neurologic deficit was assessed using the American Spinal Injury Association (ASIA) score,including grade A in 24 patients,grade B in 22,grade C in 26,grade D in 37 and grade E in 76.Eighty patients were managed by simply anterior surgery,97 by posterior surgery,and eight by anterior-posterior surgery.Twenty-one patients were found with dural tears (group A) and 164 patients without dural tears (group B).Incidence of dural tears in cervical,thoracic and lumbosacral vertebral fractures were recorded and compared.Preoperative neurologic deficit,laminar fracture and spinal canal encroachment rate were compared between groups.Neurological function and complications associated with dural repair were detected.Results In group A,ten patients were rated ASIA grade A,five grade B,three grade C,one grade D and two grade E.In group B,14 patients were rated ASIA grade A,17 grade B,23 grade C,36 grade D and 74 grade E.Group A accounted for 11％ (7/65) of cervical,10％ (5/51) of thoracic,and 13％ (9/69) of lumbosacral spine fractures (P ＞ 0.05).Nineteen patients (91％) in group A were complicated with neurological deficit,compared to ninety patients (54.9％) in group B (P ＜ 0.01).Eighteen patients (86％) in group A had laminar fractures,compared to fifteen patients (9.1％) in group B (P ＜ 0.01).In group A,rate of spinal canal encroachment was (62.3 ± 12.1)％ and 17 patients (81％) showed spinal canal encroachment of greater than 50％.While in group B,rate of spinal canal encroachment was (36.2 ± 15.6)％ and 25 patients (15.2％) showed spinal canal encroachment of greater than 50％ (P ＜ 0.01).For dural tears in group A,11 patients were treated by direct suturing,four by thoracolumbar fascia repair,three by artificial dural coverage and three by fibrin glue sealing.In group A,19 patients were followed up and one of them presented persistent cerebral spinal fluid leak that necessitated an irrigation and debridement to cure.ASIA score was improved from grade A to B in two patients,grade B to C in one,grade C to D in one and grade D to E in one at the final follow-up.Conclusions Majority patients with spinal fractures associated with dural tears exist severe neurologic deficit,spinal canal encroachment and laminar fractures.Incidence of dural tear in cervical,thoracic and lumbosacral vertebral fractures is similar.Incidence of complications related to dural tear repair is low,but the neurological function recovery is poor after operation.

OBJECTIVETo investigate the clinicopathological characteristics, diagnosis and treatment of primary testicular yolk sac tumor (YST).

METHODSWe studied 8 cases of primary testicular YST by microscopy and immunohistochemistry.

RESULTSThe 8 cases of primary testicular YST, including 2 consultation cases, were confirmed from 1998 to 2013, accounting for 10.7% (8/75) of all the testicular germ cell tumors diagnosed in our hospital. The patients ranged in age from 7 to 43 years, 23.9 years on average. The main clinical manifestation of the patients was painless unilateral testis swelling. Microscopically, reticular tissues, schiller-duvaI (S-D) bodies, and eosin-stain transparent bodies were seen in the tumors. One of the cases was confirmed to be simple YST, while the other 7 mixed YST. AFP was a characteristic immunophenotype marker of the tumors.

CONCLUSIONPrimary testicular YST is a rare malignancyr with poor prognosis. Its diagnosis depends on preoperative AFP test and postoperative pathology. Comprehensive treatment, including orchiectomy, chemotherapy, and radiotherapy, can prolong the survival of the patients.

With references of historical materials and modern literature regarding acupoint characteristic, a secondary analysis on the concept, origin, related factors and research methods in present research of acupoint characteristic is performed. The acupoint characteristic should be considered as an acupoint inherent attribute that could explain physiological and pathological manifestations at the same time, including location attribute and function attribute, which is related with time and treatment method. Some re-thinking on acupoint characteristic is proposed as well as advice on further research method and direction, hoping to promote the research development of acupoint characteristic.

OBJECTIVETo systematically review the effectiveness of bone substitute augmentation combined with internal fixation versus internal fixation alone in treating proximal femoral fractures in the elderly.

METHODSSubject term and keywords were searched from Pubmed, Cochrane databases and CNKI from database foundation to August 2015. Randomized controlled studies and qusi-randomized controlled studies on bone substitutes augmentation combined with internal fixation versus internal fixation alone for the treatment of proximal femoral fractures in the elderly were chosen. Postoperative re-displacement, re-operation rate, complications (infection and bone ununion), functional outcome, quality of life scores and muscle strength were seen as outcome indicators. Enumeration data were statistical analyzed by risk difference and 95% confidence interval. Measurement data were analyzed by standardized mean difference and 95% confidence interval. If the same measurement data were evaluated by different standards in different studies, standardized mean differences and 95% confidence interval were used. The methods of statistical analysis were used by Cochrane databases.

RESULTSEleven RCTs (677 patients) were included. Meta-analysis results indicated that bone substitutes augmentation combined with internal fixation occurred fewer re-displacement [SMD = -0.75, 95% CI (-1.03, -0.47)] and obtained better function [SMD = 0.40, 95% CI (0.20, 0.59)]. While there were no significant differences in reoperation rate [RD = 0.02, 95% CI (-0.05, -0.09)], pain at 1 week after operation [MD = -1.79, 95% CI (-13.55, -9.96)], pain ranged from 6 to 8 weeks [MD = -7.24, 95% CI (-20.07, -5.59)], postoperative pain at 12 weeks [MD = -0.32, 95% CI (-4.9, -3.55)], muscle strength [MD = 1.25, 95% CI (-6.98, -9.48)], bone ununion [RD = 0.02, 95% CI (-0.01, -0.05)] and postoperative complications [MD = 0.01, 95% CI (-0.03, -0.04)].

CONCLUSIONCompared with single internal fixation, bone substitutes augmentation combined with internal fixation for the treatment of proximal femoral fractures in the elderly less occur re-displacement and could obtain better functional recovery.

Multi-target drugs attract increasing attentions for the therapy of complicated neurodegenerative diseases. In this study, a computer-assisted strategy was applied to search for multi-target compounds by the pharmacophore matching. This strategy has been successfully used to design dual-target inhibitor models against both the acetylcholinesterase (AChE) and poly (ADP-ribose) polymerase-1 (PARP-1). Based on two pharmacophore models matching and physicochemical properties filtering, one hit was identified which could inhibit AChE with IC50 value of (0.337 +/- 0.052) micromol x L(-1) and PARP-1 by 24.6% at 1 micromol x L(-1).
