OBJECTIVETo verify the clinical efficacy on chronic fatigue syndrome of qi deficiency syndrome treated with acupuncture at selective time and explore the effect mechanism.

METHODSEighty patients were randomized into a selective-time-acupuncture group and an acupuncture group, 40 cases in each one. Qihai (CV 6), Guanyuan (CV 4), Hegu (LI 4), Taichong (LR 3), Sanyinjiao (SP 6) and Zusanli (ST 36) were selected in the two groups. In the selective-time-acupuncture group, acupuncture was used at 9:00am to 11:00am. In the acupuncture group, acupuncture was used at any time except in the range from 9:00am to 11:00am. No any manipulation was applied after the arrival of needling sensation. The treatment was given once every day, 10 day treatment made one session and two sessions of treatment were required. The fatigue scale was adopted to evaluate the efficacy before and after treatment in the patients of the two groups. The ratios among CD3+, CD4+ and CD8+ T cells in the peripheral blood were detected before ad b a after treatment.

RESULTSIn the acupuncture group, the total score of fatigue and the score of physical fatigue were reduced after treatment as compared with those before treatment (all P<0.05). In the selective-time -acupuncture group, the total score of fatigue, the s core of physical fatigue and the score of mental fatigue after treatment were reduced obviously as compared with those hefore treatment (all P<0. 01). The improvements in the scores of the selective-time-acupuncture group were superior to the acupuncture group (all P<0. 05). The ratio of CD3+ and CD8+ T cells was increased obviously after treatment in the two groups (all P<0. 05) and the ratio of CD4+ and CD8+ T cells was reduced obviously in the selective-time-acupuncture group (P<0. 05), which was better than that in the acupuncture group (all P<0.05). The total effective rate was 95.0% (38/40) in the selective-time-acupuncture group, which was better than 80.0% (32/40) in the acupuncture group (P<0.05).

CONCLUSIONThe acupuncture therapy at selective time is effective in the treatment of chronic fatigue syndrome of qi deficiency syndrome, which is especially better at relieving mental fatigue. The effect of this therapy is achieved probably by improving the immune function via the regulation of the ratios among CD3+, CD4+ and CD8+ T cells.

Objective To evaluate retrospectively the role of 18 F-fluorodeoxyglucose (FDG) PET/CT associated with MRI in the localization of epileptogenic foci. Methods Sixty-seven patients with medically resistant epilepsy were included from 2003 to 2008. All underwent 18F-FDG PET/CT and MRI for presurgical evaluation as well as post-surgical evaluation 12 to 65 months after operation. Based on postoperative seizure occurrence, patients were divided into two groups. One group was free of seizures ( Engel classification Ⅰ, Group 1) and the other was with postoperative seizure occurrence of any type ( Engel classification Ⅱ-Ⅳ, Group 2). X2-test or Fisher's exact test was used for the statistical analysis. Results About 71.6% (48/67) patients were defined as group 1, and 19 patients were group 2 ( 11 were Engel Ⅱ , 5 were Engel Ⅲ, and 3 were Engel Ⅳ ). In Group 1, no statistically significant difference was found between concordant (45/63) and discordant findings (3/4) with regard to 18F-FDG PET/CT and MRI images (Fisher's exact test, P ＞0.05). For 41 patients that showed focal abnormality both on MRI and 18F-FDG PET/CT, 80.5% (33/41) were found in group 1. For 20 patients that showed focal lesions on MRI while with multi-focal or generalized abnormal metabolism on 18F-FDG PET/CT, 11 (55.0%) were in group 1 and9 (45.0%) were group 2. There was no significant difference (33/41 vs 11/20, X2 =4.34, P ＜0.05 ). Conclusion 18F-FDG PET/CT associated with MRI may offer more helpful information for pre-surgical evaluation and prediction of prognosis of epileptic patients.

Objective To study the changes of umbilical blood lactate,pH, blood sugar(BS),bilirubin, electrolyte, osmotic pressure (OP) in the newboms with fetal distress.Methods Thirty-five newborns with fetal distress (distress group) and 40 healthy new-borns (control group) were studied. Distress group were divided into distress group Ⅰ and distress group Ⅱ respectively, based on without or with neonatal asphyxia. Concentration of umbilical blood lactate was determined with enzyme method, pH, BS,serum total bilirubin (BIL), serum electrolyte (Na+ ,K+ ,Ca2+ ) and OP were analyzed respectively. Results 1. The difference of incidence of newborn asphyxia between distress groups (29.03%) and control group (2.50%) was statistically significant. 2. Compared with the controls and distress group Ⅰ, the umbilical blood lactate concentration significantly increased in distress group Ⅱ (P 0.05).The incidence of hyperglycemia was significantly elevated in distress groups than that in the control group. 4. Lactate concentration in distress I and distress fl group showed negative correlation with pH. Conclusion The concentration of umbilical blood lactate can provide the proof for diagnosis and prognosis of fetal distress.

Objective To explore brain plasticity of upper extremities motor function recovery after stroke with diffusion tensor imaging (DTI). Methods 25 stroke patients with internal capsule lesions and affected corticospinal tract (CST), 4-8 weeks after onset, were divided randomly into rehabilitation group (n=13) and control group (n=12). Both groups received routine medication and the rehabilitation group also received rehabilitation. All the patients were scanned with DTI and assessed with upper extremity Fugl-Myer Assessment (UE-FMA) before and 3 months after treatment. The fractional anisotropy (FA), FA ratio (rFA) and FA asymmetry (FAasy) in cerebral peduncle, posterior limb of internal capsule (PLIC) and corona radiate were obtained. The bilateral corticospinal tracts were reconstructed with diffusion tensor tractography. Results The scores of UE-FMA increased in both groups after treatment (P<0.05), and increased more in the rehabilitation group than in the control group (P<0.05). There was significant difference in FA, rFA and FAasy in the corona radiate section of CST after treatment in the rehabilitation group (P<0.05), but was not in the cerebral peduncle and PLIC section. However, there was no significant differences in FA, rFA and FAasy in the control group. The ipsilesional CST fibers were more compact after treatment in the rehabilitation group. Conclusion Rehabilitation can improve the upper extremities function recovery after stroke, which may associated with the repairment of CST in the corona radiate section.

Objective To study the inner diameter and hemodynamics of ophthalmic artery(OA)and central retinal artery(CRA)in hyperuricemia by Enhance-flow(eFlow)imaging and spectral Doppler.Methods One hundred and one patients with hyperuricemia and 30 volunteers were selected,the inner diameter in eFlow imaging and the peak systolic velocities(PSV),the end diastolic velocities(EDV),the resistive index(RI)were measured,and pulsatility index(PI)of OA and CRA were measured by spectral Doppler.The 101 patients were divided into two groups according to the time of diagnosing hyperuricemia,one group had a diagnosis of hyperuricemia for more than five years and the other had such a diagnosis for less than five years.The data were compared by t-test.Then,the patients were further divided into a group of hyperuricemia combined with hypertension and the other without hypertension.The differences between the experimental group and the group of volunteers were carried out by One-way ANOVA,the comparison between two groups were analyzed with SNK.Results The RI(0.68±0.09)and PI(1.3±0.4)of OA in patients who were diagnosed as hyperuricemia for more than 5 years was higher[RI:0.63±0.09,PI:1.1±0.3(t=3.504,P=0.001 ;t=3.164,P=0.002)],the EDV[(6±3)cm/s]of OA was lower than those patients with a diagnosis of hyperuricemia for less than 5 years[(8±5)cm/s,t=1.988,P=0.049].The PSV[(11.5±3.5)cm/s]and EDV[(3.7±1.1)cm/s]of CRA in hyperuricemia combination hypertension group was lower,and the RI (0.88±1.40)was higher than hyperuricemia without hypertension group[PSV:(13.5±4.0)cm/s,EDV:(4.1±1.2)cm/s,RI:0.67±0.08].Conclusion By eFlow and spectral Doppler,we have found that hyperu-ricemia could accelerate OA and CRA atherosclerosis.The eFlow and spectral Doppler are valuable methods to study the hemodynamics in ophthalmic artery of patients with hyperuricemia.

Objective To explore the relationship between corticospinal tract (CST) repairment and motor function recovery after rehabilitation in stroke patients by diffusion tensor imaging (DTI). Methods 15 stroke patients with internal capsule lesions and injured CST, 4-8 weeks after onset were included. They were scanned with DTI and assessed with the simple Fugl-Meyer Assessment (FMA) before and after 3-month rehabilitation. The fractional anisotropy (FA), FA ratio (rFA) and FA asymmetry (FAasy) in cerebral peduncle, posterior limb of internal capsule (PLIC) and corona radiate were obtained. The correlation of differences of FA, rFA and FAasy of CST with FMA was analyzed. Results The scores of FMA increased after treatment (P<0.01). The FA of the ipsilesional CST were significantly less than that of contralesional ones before and after rehabilitation. There was statistical differences in FA, rFA and FAasy in the corona radiate section of CST after treatment (P<0.05), but was not in the cerebral peduncle and PLIC section. However, there was no significant correlation of FA, rFA and FAasy of corona radiate section to scores of FMA. Conclusion DTI can respond to the repairment of corticospinal tract after stroke, especially in the corona radiate section.

Objective To explore the operative methods and clinical outcomes in emergency or sube- mergency repair for the complicated tissue defects in hand in first stage applying microsurgical technique. Methods From Jan.,2000 to Aug.,2005,49 emergency cases of complicated hand tissue defects were re- paired in the first stage with replantation,reconstruction,free flaps,combined finger reconstruction and flap transplantation,including 21 cases in mini tissue mass replantation or reconstruction,15 cases in replantation combined with free flap transplantation,8 cases in replantation and reconstruction combined with free flap transplantation,5 cases in combined multiple digits reconstruction with free flap transplantation.The free flap transplantation included the anterolateral femoral flap,the latissimus dorsi myocutaneous flap,the dorsalis pe- dis flap,the media pedis flap and the instep flap.Results All the flaps,the replanted and reconstruceted finger survived uneventfully except for one replanted finger necrosis.45 cases healed in the first stage and the other 4 cases healed in the second stage.During a follow-up from 6 months to 3 years postoperatively,a satis- factory appearance and function of the reconstructed hand was achieved.The excellent and good rate was 85.7% assessed with provisional functional assessment criterion for upper limbs issued by Chinese Society of Hand Surgery.Conclusion The emergency or subemergency repair for the complicated tissue defects in hand has the advantage of short-term treatment and desirable functional outcome.The emergency replantation and reconstruction combined with various flaps or tissue mass can be applied to repair tissue defect in hand in the first stage according to the position and area of the defect along with the technique level of the surgeon, having been proved to achieve desirable clinical outcomes.And the key points leading to a successful operation is the correct treatment for the raw surface of the defects,suitable choice for various flaps,logical design of combination pattern and prevention and timely treatment for vessel crisis.
