ObjectiveTo study the effect of early rehabilitation on disability of motion and cognition.Methods107 patients were randomly divided into two groups,rehabilitation group (51 cases) and control group (56 cases).Patients in rehabilitation group were given regular early rehabilitation,while all patients in both groups were given usual clinical treatment. The Barthel Index (BI), Fugl-Meyer Assessment (FMA), Mini-mental Status Examination (MMSE) were used to evaluate these two groups before and 3 months after treatment. ResultsAfter treatment, the scores of BI, FMA and MMSE were improved significantly(P<0.05) in rehabilitation group compared with that before treatment, so did that of BI, FMA in control group(P<0.05).The scores of BI、FMMS、MMSE in rehabilitation group improved significantly compared with that in control group(P<0.05).ConclusionEarly rehabilitation may obviously improve the motive and cognitive function and increase the quality of living of hemiplegia after stroke.

ObjectiveTo observe the effect of early rehabilitation on poststroke anxiety and depression.Methods137 stroke patients with hemiplegia were divided into the rehabilitation group (70 cases) and control group (67 cases). All patients in both two groups were given routine clinical treatment, but the patients in the rehabilitation group were given regular early rehabilitation. All patients were evaluated with Bathel Index (BI), Fugl-Meyer Motor Scale (FMMS), Hamilton Depression Scale (HAMD) and Hamilton Anxiety Scale (HAMA) before and 3 months after treatment.ResultsAfter 3 months treatment, the scores of HAMD, HAMA, BI and FMMS of patients in the rehabilitation group increased significantly compared with those before treatment ( P<0.05～0.01), and those in the control group ( P<0.05). The scores of BI and FMMS of patients in the control group after treatment also increased significantly compared with those before treatment ( P<0.05). The incidences of depression and anxiety of the rehabilitation group were 22.86% and 5.71%, those of the control group were 40.30% and 16.42%, there was a significant difference between two groups( P<0.05).ConclusionThe early rehabilitation can obviously decrease anxiety and depression of stroke patients with hemiplegia.

Objective To investigate the protective effect of sevoflurane on the brain against focal ischemia-reperfusion(I/R)injury and its mechanism.Methods Twenty-four male SD rats weighing 250-300 g were randomly allocated into 3 groups(n=8 each):group Ⅰ sham operation;grouop Ⅱ I/R and group Ⅲ I/R + sevoflurane.The rats were anesthetized with intraperitoneal chloral hydrate 300 mg?kg~(-1).Middle cerebral artery occlusion(MCAO)was produced by insertion of a 4-0 mono-filament nylon thread with rounded tip at bifurcation of right common carotid artery into internal carotid artery.The nylon thread was advanced cranially until resistance was felt.The depth of insertion was 18-20 mm.After 3 h MCAO the thread was withdrawn to allow reperfusion.In group Ⅲ the animals inhaled 1.0 MAC sevoflurane for 30 min at 30 min before reperfusion.The rectal temperature of the animals was kept at 36.5-37.5℃.At the end of 24 h reperfusion the animals were weighed again.The animals'neurological deficit was evaluated using Zea Longa score(0=no defcit,4=unable to walk and unconscious).The animals were then killed.The neuronal apoptosis in striatum was assessed(TUNEL)and the PKC protein expression in striatum was determined by immunocyto-chemistry.Results The body weight of the animals in I/R group was significantly reduced after 24h reperfusion as compared to the body weight before ischemia (P＜0.01),while in control group and sevoflurane group there was no significant difference in the body weight before and after sham operation or I/R.The neurological deficit scores were significantly higher in I/R group than in sevoflurane group.The number of apoptotic neurons in striatum was significantly higher in I/R group than in sevoflurane group.The PKC expression in striatum was significantly higher in sevoflurane group than in I/R group (P＜0.01).Conclusion 1.0 MAC sevoflurane inhalation has protective effect on the brain against I/R injury. Upregulation of PKC expression in striatum decreased by I/R is involved in the mechanism.

Objective To explore the efficacy and safety of recombinant human brain natriuretic peptide (rhBNP) in the patients with severe heart failure (HF). Methods A prospective multicenter study was conducted. Patients whose age > 18 years old, and with the New York Heart Association (NYHA) cardiac function grade overⅢ - Ⅳ , acute cardiac insufficiency and the acute exacerbation of chronic cardiac insufficiency admitted to intensive care unit/cardiovascular care unit (ICU/CCU) of 58 Hospitals in China were enrolled. On the basis of the conventional treatment, all patients would be given rhBNP (neo adjuvant) with a loading dose of 1.5 μg/kg for 3-5 minutes, and followed by a maintenance dose of 0.010-0.015 μg·kg-1·min-1 for 3-7 days. Before the treatment and 1, 3, 7 days after treatment, researchers detected indexes of cardiac and renal function, the levels of N-terminal B-type natriuretic peptide (NT-proBNP), left ventricular ejection fraction (LVEF), cardiac output (CO), pulmonary capillary wedge pressure (PCWP), central venous pressure (CVP), urea nitrogen (BUN), serum creatinine (SCr), and urine output; the renal function index was re-evaluated at 30 days after administration, and the time entering ICU again, re-admission, cardiovascular events were recorded. Results 408 patients were enrolled, with 241 males and 167 females. Age range was 28-95 years, the average age was (63.0±15.8) years, and 50-70 years old accounted for 46.8%. Compared with the data before treatment, NT-proBNP, PCWP and CVP significantly decreased at 6 hours after treatment [NT-proBNP (μg·kg-1·min-1): 4378.58±4082.29 vs. 6403.41±5759.48, PCWP (mmHg, 1 mmHg = 0.133 kPa):12.41±2.21 vs. 14.26±2.85 , CVP (mmHg): 10.63±2.62 vs. 11.45±3.45, all P < 0.05], and with the prolongation of injection, NT-proBNP, PCWP and CVP were gradually declined; CO 1 day after treatment (mL: 4.89±0.81 vs. 4.40±0.92) and LVEF 3 days after treatment (0.465±0.100 vs. 0.431±0.107) were significantly increased (both P < 0.05), and with the prolongation of injection, CO and LVEF were gradually increased. There were no obvious changes in BUN and SCr during the treatment, but 30 days after treatment, SCr was significantly lower than that pre-treatment (μmol/L: 110.98±47.40 vs. 132.62±75.60, P < 0.01). Compared with the data pre-treatment, urine output per hour was significantly increased at 3 hours after treatment (mL: 129.59±82.16 vs. 89.60±53.49, P =0.000); urine output every 24 hours was significantly increased at day 1 and day 2 after administration (mL: 2676.54± 1006.83, 2678.74±975.97 vs. 2150.36±283.76, both P < 0.01). In 7 days, the re-entry ICU rate was 2.7%, and the re-hospitalization rate was 2.88% within 30 days, re-cardiac failure rate was 1.43% in 30 days, and the overall fatality rate was 9.55% in 30 days. Conclusions The rhBNP can significantly improve heart function in patients with HF. And, it has a certain effect on renal function. The rhBNP is effective and safe for the treatment of cardiac insufficiency.

Background Neurofilament 200 (NF200) is an indirect indicator of the specific distribution of axons.It reflects the condition of the maintenance of neuronal morphology.Whether NF200 is involved in the damage of the visual pathway after retinal ischemia reperfusion injury (RIRI) should be further examined.Objective The present study was to investigate the expression of NF200 in retinal ganglion cells (RGCs),lateral geniculate nucleus (LGN),superior colliculus and visual cortex following RIRI.Methods Forty SD rats were randomized into the RIRI 1-,2-,3-,4-,6-,8-week groups,sham operation group and control group.Acute intraocular hypertension was induced in the right eye by anterior chamber perfusion of normal saline solution for 60 minutes to elevate the intraocular pressure to 110 mmHg.The animals were sacrificed at different time points for the preparation of the retina,LGN,superior colliculus and visual cortex sections.The expression of NF200 in RGCs,LGN,superior colliculus and visual cortex was assayed by immunohistochemistry.Results The expression level (A value) of NF200 in the RGCs was significantly different among the 8 groups after reperfusion (F =78.855,P =0.000),and that in the 1-week group was significantly lower than in the control group (t =36.563,P＜0.01).In the RIRI 1-week group,the expression of NF200 in the contralateral LGN in the experimental group was significantly lower than that in the control group (t =6.483,P＜0.01).In the 4-week group and 6-week group,the expression of NF200 in the contralateral LGN was significantly higher than that in the control group (t =2.904,4.313,P＜0.01).One week after RIRI,the expression of NF200 in contralateral superior celliculus in the experimental group was significantly lower than that in the control group (t =2.966,P＜0.05),and in the 2-week group,the expression of NF200 in the contralateral superior colliculus was significantly higher than that in the control group (t =7.397,P＜0.01).In the 2-week group,3-week group and 4-week group,the expression of NF200 in bilateral visual cortex was significantly higher in the experimental group than that in the control group (contralateral ∶ t =18.728,18.213,15.088,P＜0.01 ; ipsilateral ∶ t =8.690,5.704,7.805,P＜0.01).Conclusions RIRI can induce axonal damage of RGCs,contralateral LGN,superior colliculus and bilateral visual cortex neurons.

OBJECTIVETo evaluate the effect of nasogastric decompression tube after gastric cancer operation on the postoperative recovery.

METHODSA total of 174 patients with gastric cancer were prospectively enrolled from December 2009 to March 2011 and randomly divided into non-nasogastric tube control group(n=88) and nasogastric tube group(n=86). Postoperative symptoms, complications, recovery time, and quality of life during hospital stay were compared between the two groups.

RESULTSThe incidences of nausea(14.8% vs. 47.7%, P<0.01), sore throat(6.8% vs. 38.4%, P<0.01), bucking and foreign body sensation(3.4% vs. 20.9%, P<0.01), expectoration obstruction(36.4% vs. 55.8%, P<0.05) were significantly lower in nasogastric tube group than those in the control group. The intervals to ambulation and flatus were(1.46±0.58) d and(3.11±0.77) d in the non-nasogastric tube group, significantly shorter those in nasogastric tube group[(1.68±0.61) d and(3.75±1.03) d]. There was no anastomotic leak or bowel obstruction. The difference in bleeding was not statistically significant[3.4%(3/88) vs. 5.8%(5/86), P>0.05] between the two groups. The quality of life differed between the two groups(mean score, 3.36 vs. 2.78, P<0.01).

CONCLUSIONEarly removal of nasogastric decompression tube is safe and reasonable and can improve the quality of life during hospital stay.
