Objective To determine the perioperative hidden blood loss (HBL) associated with different fixation methods for intertrochanteric fracture.Methods We retrospectively studied 128 patients with 31-A1 and 31-A2 intertrochanteric fractures which underwent internal fixation with dynamic hip screw (DHS,n=35),short reconstruction intramedullary hip screw (IMHS,n=55) or percutaneous compression plate (PCCP,n=38) from January 2008 to January 2012.The HBL were calculated and compared.Results The mean total hidden blood loss (THBL) was more than 7 times than the mean apparent blood loss (ABL) in all the three groups.For the THBL,there were significant statistical differences among three groups; no difference was found between IMHS and DHS group.For the phasic hidden blood loss (PHBL),there was no difference among the three phase of treatment in DHS group.But in IMHS and PCCP group,there were significant differences between the 4th-5th day and the 1st day,the 2nd-3rd day after operation; no difference was found between the Ist and the 2nd-3rd day.For the ratio of PHBL/THBL there were significant differences between the 4th-5th day and the 1st day,the 2nd-3rd day after operation; but no statistical differences were found between the 1st day and the 2nd-3rd day after operation.Conclusion It can be concluded that HBL after surgery for intertrochanic fractures is much greater than that observed intra-operatively.The IMHS and DHS cause more HBL than PCCP.Frequent post-operative measurements of haemoglobin are necessary,especially the first three days after surgery.

Major depression disorder is an increasing heavy burden in modem society, but its pathological mechanism is still vague. Recent evidence indicated that two pore potassium channel, TREK1, is one of the important drug targets of antidepressants. The structural and functional research progress of TREK1 potassium channel were reviewed with an emphasis on its roles in anti-depression, neuronal protection, and neuronal plasticity. The complicated interactions between TREK1 potassium channel and monoamine transmitters-receptors were also reviewed and future directions to explore the underline mechanism were also discussed.

OBJECTIVE To investigate the situation of the tumor patients with subsequent bacteremia in hospital in order to study the some prevention and controlling measures. METHODS Ten cases in the internal medical department for tumor with the central venous pressure apparatus were analyzed and had the symptom of chilling and hyperpyrexia , and then were carried through the germiculture for the central venous catheter. RESULTS Pathogenic microorganism had been isolated from the hemoculture. CONCLUSIONS Once the patients with the central venous pressure apparatus have the symptoms of unknown infection, it must be consider the possibility of contaminated tube and conduct countermeasures in time.

Objective To verify the presence of anti-ovary antibodies in systemic lupus erythematosus (SLE) and its possible correlations with serum levels of hormone profile and menstrual disturbances in patients with SLE.Methods Clinical data of 78 consecutive paticnts who fulfilled 4 or more of the ACR 1997 revised criteria for SLE were studied and compared with 40 age-matched healthy controls,including anti-ovary antibodies.Results 27 (34.6％ ) patients with SLE,and 1 (2.5％) of the healthy controls tested positive of anti-ovary antibodies.The levels of E2 and T and P decreased[ E2:( 80.96 ± 36.2 ) ng/L vs ( 118.53 ± 42.4 ) ng/L; T:( 3.85 ± 1.18 ) nmol/L vs ( 6.43 ± 2.28 ) nmol/L; P:( 1.37 ± 0.59 ) μg/L vs ( 3.92 ± 1.23 ) μg/L],and the levels of FSH and LH and PRL increased in SLE patients when compared with healthy controls [ FSH:( 19.17 ± 9.26)IU/L vs (10.18 ±7.27 )IU/L; LH:( 21.19 ± 12.44)IU/L vs (13.79 ±8.27)IU/L;PRL:(6.18 ± 2.27 ) μg/L vs (2.37 ±0.63)μg/L,P ＜0.05 orP ＜0.01].The higher SLEDAI score,higher rate of menstrual disturbances (6.3 ±2.8 vs 3.5 ± 1.7,81％ vs 47％,P ＜0.05 or P ＜ 0.01 ) and decreased serum level of E2 [ (64.13 ± 26.36 ) ng/L vs ( 82.83 ± 28.71 ) ng/L,P ＜ 0.05 ]were found in SLE patients with anti-ovary antibodies positive than in SLE patients with anti-ovary antibodies negative.Conclusions The presence of anti-ovary antibodies was 34.6％ in SLE,and may correlate to decreased serum level of E2 and menstrual disturbance.

Objective Recently, the role of TREK-1 in anti-depression and neuroprotection was demonstrated definitely.In this paper,a systematic review about the functional structure of TREK-1 as well as the underlying mechanisms which involved in depression resistance and nerve protection was made for purpose of providing new ideas for the treatment of clinical diseases.Methods The electronic search of Medline/PubMed,CNKI,CBM and Wanfang Data were performed to collect the introduction of TREK-1 and the studies of depression and nerve protection in which TREK-1 participated from inception of each database to October 2015 ,besides the relevant references of the included studies were also retrieved.Results 30 studies were included in this paper.14 studies were about the interpretation of TREK-1's structure, distribution and the regulatory factors, and the number of researches regarding the involvement of TREK-1 in anti-depression and neuroprotection was 13 and 7 respectively.Based on these studies,it was easily to conclude that inhibition or blocking of TREK-1 channels can produce obvious antidepressant effect, however, activation of TREK-1 channels will induce the dilation of local cerebral vascular and silence hyperactive neurons.Conclusion Some achievements about the antidepressant and neuroprotective effect of TREK-1 channels in vivo have been made gratifyingly,thus future research should focus on exploring the best TREK-lactivation ratio in different brain regions to gain the best balance between anti-depression and neuroprotection.

In the acupuncture treatment, the results showed remarkable effect in 4 cases, effect in 21 cases. In the routine treatment, the results showed remarkable effect in 4 cases and effect in 8 cases. Conclusion: acupuncture treatment is better than the routine conventional treatment for lameness caused by lumbar spinal stenosis.

ObjectiveTo explore the mechanism of protection of 2,3,5,4'-tetrahydroxy stilbene-2-O-β-D-glucoside(TSG) on brain.MethodsThe bilateral carotid arteries of mice were occluded and then reperfused. The mice were sacrificed to get the brain tissue. Brain water content(BWC) was assayed by dry-wet method; malondialdehyde (MDA) content was determined by thiobarbiturate method and the activity of superoxide dismutase(SOD) was estimated by nitrite salt assay.ResultsBWC of model group was significantly higher than that of sham-operation group, while the TSG treatment reduced the BWC remarkably in mice with ischemia-reperfusion. SOD activity of model group was significantly lower than that of sham-operation group, while MDA content increased remarkably. Comparing with the model group, the SOD activity of mice treated with TSG was higher and the MDA content was lower.ConclusionTSG may reduce brain edema, improve the anti-oxidative ability of the brain tissue, and therefore, have protective effects on the brain.
