Research of PQRS in evaluating the quality of postoperative recovery in the patients with lung cancer / 中国康复医学杂志

Objective:To research the quality of postoperative recovery of patients with lung cancer through the(PQRS),and compare the recovery quality after video-assisted thoracoscopic surgery (VATS) or traditional open lobectomy.Method:PQRS scale was used to evaluate the recovery of 140 patients with lung lesions preoperatively and postoperative 1 day,3 days,7 days,14 days and 1 month.95 patients who met the set standard and complete the PQRS scales were enrolled and divided into video-assisted thoracoscope group or traditional thoracotomy group.This article mainly compared and analysied the quality of postoperative recovery of patients in both groups.Result:Except the anesthesia time,other general datum showed no statistical difference.In total recovery rate,the video-assisted thoracoscope group has significant difference when compared with the traditional thoracotomy group(P ＜ 0.05).The recovery rates of VATS group in feeling of the harmful factors,emotional factors and the daily life are higher than that of the traditional thoracotomy group,with statistically significant differences(P ＜0.05).However,the recovery rates in the physiological factors and cognitive factors had no statistical difference between two groups(P＞ 0.05).Conclusion:PQRS can effectively evaluate the quality of postoperative recovery in patients with lung cancer,and VATS is helpful to quick recovery postoperatively.

Expression and Role of CXCL1 in Patients with Severe Traumatic Brain Injury / 中国康复理论与实践

Objective To explore the cellular localization of chemokine (C-X-C motif) ligand 1 (CXCL1) in brain tissue and its expres-sion in brain tissue and blood in patients with severe traumatic brain injury (TBI), as well as its correlation with the injury severity. Methods From September, 2013 to October, 2015, 78 cases of TBI with craniotomy admitted to our hospital were involved as TBI group. A total of 78 peripheral blood samples and 19 brain tissue samples were studied. According to the scores of Glasgow Coma Scale (GCS) at admission, the TBI group was classified as severe TBI group (6~8, n=35) and particularly severe TBI group (3~5, n=43). Ten cases of control brain tissue were taken from patients with cerebral aneurysms or benign tumor and also undergoing craniotomy during the same time. Peripheral blood from ten healthy people were involved as the healthy control group. Immunofluorescent double staining was used to detect the cellular local-ization of CXCL1 in brain tissues, and ELISA was used to detect the expression of CXCL1 in brain tissue and blood. The relationship be-tween the level of CXCL1 in peripheral blood at different time and the score of Glasgow Outcome Scale (GOS) was analyzed with Spear-man correlation analysis. Results In normal brain tissue, CXCL1 mainly localized in astrocytes. For severe TBI, CXCL1 mainly expressed in neurons and astrocytes. The level of CXCL1 was higher in brain tissue in the particularly severe TBI group than in the severe TBI group (t=-12.58, P0.05). In the particularly severe TBI group, the level of CXCL1 in blood reached a peak before and one day after surgery, then gradually decreased, and was still higher than that in the healthy control group 30 days after surgery (P<0.05). The level of CXCL1 in blood was higher in the particularly severe TBI group than in the severe TBI group at all time points (P<0.05), and the level before surgery was negatively correlated with the score of GOS in the particularly severe TBI group (r=-0.351, P<0.05). Conclusion The CXCL1 protein of injury brain tissue was mainly colocalized in neurons and astrocytes in severe TBI patients, and the ex-pression was associated with injury severity and outcome.

Clinical Observation of Hyperbaric Oxygen Combined with Flupentixol and Melitracen in the Treatment of Post-stroke Depression / 中国药房

OBJECTIVE:To investigate the effects of hyperbaric oxygen combined with flupentixol and melitracen on depres-sion improvement,extremity motor function and ability of daily living and activity in patients with post-stroke depression (PSD). METHODS:60 PSD patients were divided into control group and observation group according to random number table,with 30 cases in each group. Both groups received routine clinical treatment,comprehensive rehabilitation therapy and psychotherapy. The control group was additionally given Flupentixol and melitracen tablets,orally,one tablet each time,in the morning;3 days later, one tablet each time,in the morning and noon,for 4 weeks. Other anti-depressive agents were not given during treatment. Observa-tion group was additionally given hyperbaric oxygen,0.12 MPa,for 90 min,qd,5 times a week,for 4 weeks,on the basis of control group. Depression degree [Hamilton depression scale (HAMD) and Self-rating depression scale(SDS)],extremity motor function [Fugl-Mayer motor function assessment (FMA)] and ability of daily living and activity [modified Barthel index (MBI)] were scored in 2 groups before and after treatment,and ADR was observed. RESULTS:After 4 weeks of treatment,HAMD and SDS of 2 groups were decreased significantly compared to before treatment,while FMA and MBI were increased significantly;the improvement of observation group was significantly better than that of control group,with statistical significance(P<0.05). No ob-vious ADR was found in 2 groups. CONCLUSIONS:Hyperbaric oxygen combined with flupentixol and melitracen can effectively improve PSD,relieve negative emotion and improve extremity motor function and ability of daily living and activity.

Highly Sensitive Fluorescent Aptasensor for Thrombin Detection Based on Competition Triggered Rolling Circle Amplification / 分析化学

Based on the competition reaction of target protein, aptamer probe, padlock probe and complementary sequence, a highly sensitive fluorescent aptasensor was developed in this study in combination with rolling circle amplification. In the absence of target protein, the ligation-rolling circle amplification reaction was repressed because the complementary sequence hybridized with aptamer probe to form double-stranded duplex. While in the presence of target protein, the target molecules bound specifically with aptamer probe, inducing displacement of the complementary sequence and hybridization with padlock probe. The padlock probe was circularized with the assistance of E. coli DNA ligase, and the rolling circle amplification process could be accomplished by Phi 29 DNA polymerase. The amplification product contained thousands of repeated sequences which could hybridize with the loop of molecular beacon ( the detection probes) , resulting in a significant fluorescence signal. The effects of length of complementary DNA ( CDNA ) sequence and concentration of padlock probe were investigated. Under the optimized experimental conditions, the model target protein thrombin could be highly sensitively detected by the proposed aptasensing system in a linear range of 0 . 067-32 . 4 nmol/L with a detection limit of 0 . 03 nmol/L ( approximately 90 amol target molecules). Moreover, the presented sensing method was universal for other target analysis by skillfully design of the sequence of aptamer probe and related oligonucleotides.

The effects of rehabilitative training on neural function and the expression of glial fibrillary acidic protein and ionized calcium binding adaptor molecule-1 after traumatic brain injury / 中华物理医学与康复杂志

Objective To study the effectsof rehabilitative training on neural function and the expression of glial fibrillary acidic protein (GFAP) and ionized calcium binding adaptor molecule-1 (Iba-1) in rats after traumatic brain injury.Methods A left hemisphere traumatic brain injury model was established in ninety Sprague-Dawley rats.They were then randomly divided into a rehabilitation training group,an immobilization group and a free-running group,with 30 rats in each group.Another thirty rats received sham injury as the shamoperated group.Beginning 4 days post-operation the rats of the rehabilitation training group were given balancing,rotating and walking exercises three times daily,15 min/time,6 d/week.The immobilization group was fixed in mesh cages.The rats of the free-running and sham-operated groups were reared in normal cages without any special training exercise.The rats of all 4 groups were given neural and motor function tests to assess the functional outcome.Immunofluorescence staining was used to evaluate the expressions of GFAP (the marker of astrocytes) and Iba-1 (the marker of microglia) in the cortex close to the iujured region at 3 days,1 week,2 weeks,3 weeks and 4 weeks after injury.Results The average neural and motor function test scores in the rehabilitation training group were significantly better than those in the immobilization and free-running groups at the 2nd week and thereafter.The average scores in the free-running group were significantly better than those in the immobilization group at the 4th week after injury.The immunofluorescence staining showed that the expression of GFAP was lowest in the rehabilitation group at the 2nd week and thereafter.Iba-1 expression was significantly lower only at the 3rd week and beyond.Conclusion Rehabilitative training can improve nerve function recovery in rats after traumatic brain injury,and the functional enhancement may be partially attributed to the downregulation of activated astrocytes and microglia.

Effect of all-trans retinoic acid on the expression of matrix metalloproteinases-9 in perihematomal brain tissue after intracerebral hemorrhage in rats / 国际脑血管病杂志

Objective To investigate the effect of all-trans retinoic acid (ATRA) on the expression of matrix metalloproteinases-9 (MMP-9) in perihematomal brain tissue after intracerebral hemorrhage in rats.Methods Forty Sprague-Dawley rats were randomly allocated into ATRA and normal saline control groups.Each group was redivided into 2 h,48 h,72 h,and 7 d subgroups (n = 5 in each subgroup).The autologous blood was injected into the rat caudate nucleus for establishing a model of intracerebral hemorrhage under the guidance of stereotaxic apparatus.Intraperitoneal ATRA (1 mg/d) and the same volume of saline were injected respectively after the success of modeling.The expression of MMP-9 at different time points was detected by using immunohistochemical staining.Results The expression of MMP-9 in microvascular endothelial cells in perihematomal brain tissue in rats was upregulated 24 h after intracerebral hemorrhage in the ATRA and normal saline control groups,and it reached the peak at 48 to 72 h.The expression of MMP-9 in the ATRA group at different time points was lower than that in the normal saline control group (all P＜0.05).Conclusions ATRA inhibits the expression of MMP-9 in perihematomal brain tissue after intracerebral hemorrhage in rats,and thus may reduce the brain edema.

STUDY ON APOPTOSIS OF FffiROBLASTS DERIVED FROM THE SURROUNDING SKIN OF KELOIDS / 解放军医学杂志

The aim of this study was to investigate if there are abnormal fibroblasts derived from the skin surrounding keloids in order to have a better understanding for keloid progression. All the samples were used for cell culture. Flow cytometry was used to compare the apoptotic rate of fibroblasts derived from keloid and its surrounding skin, when it was cultured in serum-deprived medium for 24 hours or was induced by Fas antibody. After cultured in serum-deprived medium for 24 hours, the apoptotic rate of fibroblasts derived from the surrounding skin of keloid increased to an amount between that of normal skin and keloids. The apoptotic rate of normal skin fibroblasts increased more than that of keloids. Moreover, when induced by Fas antibody, the apoptotic rate of fibroblasts derived from the surrounding skin increased not so high as that of normal skin(P0. 05). Therefore, at least there are some fibroblasts in the surrounding skin of keloids, in which apoptosis can not be induced as in normal skin.
