This study was set up to observe the changes in stress and immune functions in upper abdominal surgery after general anesthesia.In thirty elective upper abdominal operation patients,general anesthesia was induced with propofol,fentanyl,scoline and maintained with isoflane and atrumium. Catecholamines(CA),cortisol,interleukin-2(IL-2) and soluble interleukin-2 receptor(sIL-2R) were measured before anesthesia,after induction of anesthesia,at the end of operation,and on the first and third postoperative days.The results showed that epinephrine(E),norepinephrine(NE) concentration increased at the end of operation and on the first postoperative day(P<0.01)，Cortisol concentration decreased after anesthesia induction(P<0.05)，IL-2 concentration decreased at the end of operation(P<0.05)，and sIL-2R lever did not change.The investigation suggested that general anesthesia with propofol,fentanyl and isoflane can suppress CA and cortisol increase resulting from induction of anesthesia. There was no change in IL-2 level.However it can not suppress the increase of stress hormones and decrease of IL-2 due to operation.The stress response correlate with immune functions.

OBJECTIVETo observe the effects between acupuncture combined with rehabilitation and simple rehabilitation for shoulder pain after stroke, and to select the best plan of acupuncture manipulations at different stages by orthogonal design.

METHODSNinety patients were treated with comprehensive rehabilitation, and nine cases without acupuncture were arranged into a control group. Eighty-one patients of orthogonal design were applied by acupuncture with the same acupoints and course. The VAS score and its weighted value were regarded as the observation indices,and the effects between the acupuncture group and the control group were compared. The optimal plans of acupuncture manipulations of the early stage and the later stage were chosen after the first course treatment and the third course treatment separately. The acupuncture depth (factor A:A: shallow depth less than 25 mm, A(II): modest depth 25-40 mm, A(III): deep depth 40-50 mm), the acupuncture angle (factor B:B(I): perpendicular insertion, B(II): horizontal insertion, B(III): oblique insertion), needle manipulated frequency (factor C: C(I): zero time, C(II): one time, C(III): three times) and needle retained time(factor D:D(I):20 min, D(II): 30 min, D(III): 60 min) were studied. The differences among all factors and the diversity among major factors at different stages were analyzed.

RESULTS(1) Acupuncture combined with rehabilitation at the early and the later stage acquired better improvement than simple rehabilitation (all P < 0.01). (2) The optimal acupuncture manipulation plan at the early stage was A(III) B(III) C(I) D(I), which was deep acupuncture and oblique insertion for 20 min with zero-time manipulation; the optimal acupuncture manipulation plan at the later stage was A(III) B(III) C(III) D(I), which was deep acupuncture and oblique insertion for 20 min with three-time manipulation. (3) There was significance for acupuncture depth and angle at the early stage (both P < 0.01) and there was significance for insertion depth, acupuncture angle and manipulating frequency at the later stage (all P < 0.05). (4) At the early stage, the insertion depth was statistically significant between A(I) and A(II), A(I) and A(III), A(II) and A(III) (P < 0.05, P < 0.01), and the statistical significance was existed between B(I) and B(III) (P < 0.01). At the later stage, the insertion depth was statistically significant between A(I) and A(III), A(III) and A(II), A(I) and A(II) (P < 0.05, P < 0.01), and the statistical significance was existed between C(I) and C(III), C(II) and C(III) (P < 0.05).

CONCLUSIONAcupuncture combined with rehabilitation acquire apparent effect for shoulder pain after stroke. At the early stage,the optimal plan is deep and oblique insertion for 20 min with zero-time manipulation. At the later stage, the best plan is deep and oblique insertion for 20 min with 3-time manipulation.

Objective To investigate the risk factors and clinical characteristics,auxiliary examination char-acteristics,treatment and prognosis for acute stroke patients with deep vein thrombosis (DVT),in the hope of provi-ding the detailed clinical data for hospitalized patients with stroke in early prevention,early diagnosis and early treat-ment of DVT.Methods 160 cases of stroke patients were reviewed including 66 cases of patients with hemiplegia after stroke and ultrasound confirmed DVT data analysis,And compared with the same period of 94 cases of DVT in patients with stroke.The purpose of this study was to evaluate the incidence of DVT,possible risk factors,and clinical characteristics.Results Stroke in patients with DVT spent an average of 16d.DVT occurred in elderly patients (65 years or higher) with 44 cases,accounting for 66.67%;Serious paralytic 42 cases (72.72%),long-term bed 52 cases (78.78%);The most commonly comorbid disease was diabetes mellitus,hypertension and hyperlipidemia;The plasma fibrinogen concentration was (5.02 ±1.38) g/L,which was significantly higher than (2.74 ±1.65) g/L of the control group.Compared with control group,the difference was statistically significant (t=4.78,P<0.01). Conclusion Limb paralysis,long-term lie in bed,older age and high condensation state are DVT risk factors,which should be paid to prevent in advance clinically.

BACKGROUND:Disc functional magnetic resonance imaging studies are mostly carried out under lying and a non-load state, and do not reflect the changes in morphology and function of the upright human body under disc load conditions. Therefore, we need to study characteristics of disc functional magnetic resonance imaging in the upright state. OBJECTIVE: To analyze the effect of axial load on apparent diffusion coefficient and T2 of intervertebral discs. METHODS:The study consisted of 17 patients with low back pain aged 34-65 years. Before and after axial load, T2 weighted MR imaging, T1 weighted MR imaging, diffusion tensor imaging, and T2-mapping imaging of the lumbar spine were performed. Load quality was 40%-50% body weight. At 10 minutes after axial load, another diffusion tensor imaging was performed. After 15-minute load, another T2-mapping sequence was scanned. Diffusion tensor imaging scan parameters: single echo-planar imaging, repetition time 2 500 ms, echo time 89 ms, six diffusion directions, b value of 400 s/mm2, sweep time 4:10 minutes. Raw data of diffusion tensor imaging were used to construct apparent diffusion coefficient map and b0 map. Apparent diffusion coefficient value of intervertebral discs was calculated before and after loading. T2 map was automaticaly constructed using T2-mapping sequence to measure apparent diffusion coefficient and T2 values in the whole intervertebral disc of nucleus pulposus, and the changes of them were analyzed under short-time axial load. RESULTS AND CONCLUSION:Pfirrmann grading results in 17 patients with 85 discs were obtained as folows: 0 in Grade I, 26 in Grade II, 19 in Grade III, 30 in Grade IV, and 10 in Grade V. Al 85 disc T2 relaxation time mapping and 84 disc apparent diffusion coefficient mapping were accepted. Under short-time axial load in 84 discs, apparent diffusion coefficient reduced in the whole disc (reduced 38×10-3 mm2/s,Z=2.567,P < 0.05) and nucleus pulposus (reduced 62×10-3mm2/s,Z=3.461,P < 0.05). Apparent diffusion coefficient changes mainly affected Grade Pfirrmann III discs (reduced 55×10-3mm2/s,Z=2.556,P < 0.05). T2 changes mainly affected normal intervertebral discs (Pfirrmann grade II). Under the load, T2 value of intervertebral discs diminished (reduced 3.17 ms,Z=2.967,P < 0.05). No significant difference in apparent diffusion coefficient and T2 value was detected under the load in other grades of the intervertebral discs (P > 0.05). These results suggest that changes in apparent diffusion coefficient and T2 values were different due to different Pfirrmann grades under short-time axial load. To evaluate magnetic resonance imaging function of intervertebral discs, we should choose different evaluation method according to different degeneration degrees.
