Objective To investigate the alterations of peripheral blood T lymphocyte subsets in patients with sepsis and septic acute kidney injury, and explore the clinical significance.Methods Fifty-five patients with sepsis and forty-three patients with septic acute kidney injury were enrolled in this study. At the same period, thirty healthy subjects were enrolled as the control group.T lymphocyte subsets inclu-ding CD3 +T, CD4 +T, CD8 +T cells, and CD4 +T/CD8 +T in peripheral blood were detected by flow cy-tometry, and acute physiology and chronic health evaluation Ⅱ( APACHE Ⅱ) were graded within twenty-four hours after admission.Then, correlation of the APACHEⅡscores and T lymphocyte subsets was ana-lyzed.Results In the septic acute kidney injury group, peripheral blood CD3 +T, CD4 +T cell percenta-ges, and CD4 +T/CD8 +T ratio were significantly lower than those in the control group and the sepsis group (all P <0.05).In the septic acute kidney injury group with stage 3, CD3+T, CD4 +T cell percentages, and CD4 +T/CD8 +T ratio in the patients were significantly lower than those in stage 1 and stage 2 ( all P <0.05).In the septic acute kidney injury group,CD3 +T, CD4 +T cell percentages, and CD4 +T/CD8 +T ra-tio were significantly lower in dead group than those in survival group (all P <0.05).APACHEⅡscores in patients with sepsis were significantly negatively correlated with peripheral blood CD4 +T cell percentages and CD4 +T/CD8 +T ratio ( r =-0.645,-0.492, allP <0.05).Conclusions There are varying de-grees of cellular immune imbalance in patients with sepsis and septic acute kidney injury, characterized by decline of circulating CD3 +T, CD4 +T cell percentages, and CD4 +T/CD8 +T ratio.CD4 +T cell percenta-ges and CD4 +T/CD8 +T ratio are closely related to the severity and prognosis of septic acute kidney injury.

Objective To observe the effect of Ti-6AL-4V particles on morphological and func- tional changes of osteoclast in vitro.Methods Mature osteoclasts separated from New Zealand Rabbits were cultured on glass slices and cortical bone slices.The experimental group was stimulated by Ti-6AL- 4V particles at concentration of 0.1 mg/ml.The cells were stained with TRAP at different culture time to observe the morphological variety.The bone resorption pits on bone slices were stained by toluidine blue and the resorption areas analyzed by computer image analysis software.Results Osteoclasts phagocy- tosed the particles,with irregular shapes,deeper TRAP stain and earlier apoptosis.Stimulation by Ti- 6AL-4V particles brought about larger area of bone absorption lacuna.Conclusion Osteoclasts have the ability to phagocytose Ti-6AL-4V particles,which leads to morphological and functional changes and enhances bone resorption.

OBJECTIVETo compare the difference in the clinical efficacy on posterior circulation ischemia between acupuncture at stellate ganglion and conventional acupuncture as well as the impacts on blood pressure.

METHODSEighty cases of posterior circulation ischemia were randomized into an observation group (40 cases) and a control group (40 cases). In the observation group, acupuncture was applied to the bilateral stellate ganglions on the neck, stimulated with reinforcing technique by rotating the needles. In the control group, the acupuncture of reducing technique was applied to Fengchi (GB 20), Baihui (GV 20), Neiguan (PC 6) and Taichong (LR 3) in the excess syndrome. The even needling or reinforcing technique was applied to Fengchi (GB 20), Baihui (GV 20), Ganshu (BL 18), Shenshu (BL 23) and Zusanli (ST 36) for the deficiency syndrome. The treatment was given once every 3 days and 4 treatments were required totally in the two groups. The changes in total syndrome score, peak Systolic blood flow velocity (Vp) of vertebral artery and basilar artery, systolic and diastolic blood pressures were compared before and after treatment in the two groups. The clinical efficacy was compared between the two groups.

RESULTSThe total syndrome score was reduced apparently after treatment compared with that before treatment in the two groups (P < 0.01), and the reducing was more obvious in the observation group as compared with that in the control group (P < 0.01). The total effective rate was 87.5% (35/40) in the observation group, higher than 67.5% (27/40, P < 0.05) in the control group. After treatment, the reduced Vp of vertebral artery was not improved apparently as compared with that before treatment in the control group, Vp in blood velocity abnormality (including vascular spasm, stenosis or reduced velocity) of vertebral artery and basilar artery was all improved as compared with that before treatment in the two groups (P < 0.01), and the improvements in the observation group were more obvious than those in the control group (P < 0.01). After treatment, the systolic and diastolic pressures were reduced as compared with those before treatment in the two groups, and the reduced systolic and diastolic pressures in the observation group were more apparent than those in the control group (P < 0.01).

CONCLUSIONAcupuncture at stellate ganglion achieves the satisfactory efficacy in the treatment of posterior circulation ischemia and the significant efficacy of reducing blood pressure, more advanced than the conventional acupuncture.

[Ab]stract] Objective To investigate, according to core myodynamic theory, the clinical efficacy of electroacupuncture at Huatuo jiaji points in treating motor dysfunction in stroke patients during the flaccid paralysis stage.Methods Sixty stroke patients in the stage of flaccid paralysis were randomly allocated to treatment and control groups, 30 cases each. The control group received basic treatment and conventional acupuncture and the treatment group, electroacupuncture at Huatuo jiaji points in addition. The simplified Fugl-Meyer assessment (FMA) score and the Modified Barthel Index (MBI) score were counted before and after treatment and the clinical therapeutic effects were compared between the two groups.Results There were statistically significant pre-/post-treatment differences in the FMA score and the MBI score in the two groups (P<0.05). There were statistically significant post-treatment differences in the FMA score and the MBI score between the treatment and control groups (P<0.05). The total efficacy rate was 96.7% in the treatment group and 86.7% in the control group; there was a statistically significant difference between the two groups (P<0.05).Conclusion Electroacupuncture at Huatuo jiaji points has a promoting effect on the rehabilitation of limb function in the flaccid paralysis stage of stroke.

OBJECTIVE: To explore the methods to assess the function disorder of patients with mild psychiatric impairment due to road traffic accidents. METHODS: In contrast to that of the patient with physical impairment, the function disorder of the patient with mild psychiatric impairment was assessed by the standard assessment instruments, such as the Barthel index of ADL (BI), Functional Activities Questionnaire (FAQ), Social Disability Screening Schedule (SDSS), Activity of Daily Living Scale (ADL), Physical Self-maintenance Scale (PSMS), and Instrumental Activities of Daily Living Scale (IADL). RESULTS: Except BI, the each total score of FAQ, SDSS, ADL, PSMS, and IADL correlated well with the rank of psychiatric impairment. The difference of each total score of rating scales among different physical impairment rank was not statistically significant. At the impairment rank of level 10, the difference of each total score of FAQ and ADL was not significant between the two groups; each total score of BI, SDSS, and IADL in psychiatric impairment was higher than that of physical impairment, while the total score of PSMS in psychiatric impairment was lower than that of physical impairment. At the level 9, except PSMS, the each total score of BI, FAQ, SDSS, IADL and ADL in psychiatric impairment was higher than that of physical impairment. At the level 8, except BI and PSMS, the each total score of FAQ, SDSS, IADL and ADL in psychiatric impairment was higher than that of physical impairment. CONCLUSION The different criteria for assessment of mild psychiatric and physical impairment may exist, and appropriate indexes for assessment between physical and psychiatric impairment need to be further elucidated.

Objective To compare the difference of the clinical efficacy on post-stroke shoulder-hand syndrome treated by acupuncture at stellate ganglion and by conventional acupuncture. Methods Ninety cases of post-stroke shoulder-hand syndrome ( at stageⅠ or stageⅡ) were randomized into treatment group and control group, 45 cases in each group. Both groups received basic rehabilitation training. Additionally, the treatment group received acupuncture at the bilateral stellate ganglions of the neck, with reducing acupuncture by rotating the needles. The control group received the conventional acupuncture on Jiquan ( HT 1) , Chize ( LU 5) , Jianyu (LI 15), Quchi (LI 11), Shousanli (LI 10), Hegu (LI 4), with reducing acupuncture by lifting and thrusting the needle on Jiquan ( HT 1) and Chize ( LU 5) , and with mild reinforcing and reducong acupuncture on the other acupoints. The treatment for both groups was given once every day, and 14 times in total. The total syndrome scores, visual analogue scale (VAS) scores, modified Fugl-Meyer Assessment of motor function scale (FMA) scores, and modified Barthel index (MBI) were observed to evaluate the changes of symptoms, pain and motor function of the upper limbs, and activity of daily life before and after treatment in the two groups. The clinical efficacy was also compared between the two groups. Results The total syndrome scores, VAS scores, FMA scores and the modified Barthel index were improved apparently after treatment in the two groups (all P<0.01), and the improvement in the treatment group as more obvious (all P<0.01) . The total effective rate was 93.33% (42/45) in the treatment group, which was better than 73.33% (33/45) in the control group ( P<0.05) . During the treatment, patients of both groups had good compliance, and all completed the trial. No obvious adverse reaction was found in the two groups. Conclusion Acupuncture at stellate ganglion is effective and safe for the treatment of post-stroke shoulder-hand syndrome, and it has higher efficiency than the conventional acupuncture.

OBJECTIVETo investigate the effectiveness of human insulin-like growth factor I (hIGF-I) gene transferred into the cultured goat bone marrow mesenchymal stem cells with liposome, and find a new method of cell-mediated gene therapy.

METHODSBone marrow was extracted from adult goats and cultured in vitro by monolayer. Then the recombinant eukaryotic expression plasmid pIRES2-EGFP-hIGF was transfected into cells by FuGene 6. After transfection, the marker gene coding enhanced green fluorescent protein (EGFP) was observed at different time points. The hIGF concentration in the supernatant fluids was measured by enzyme-linked immunosorbent assay (ELISA) and immunohistochemistry stain of hIGF was performed to detect the target protein. Besides, reverse transcription polymerase chain reaction and flow cytometry were also adopted in order to find out the changes of cells after transfection.

RESULTSBone marrow stem cells were all in the long shuttle-like shape and adhered to the disk. The expression of EGFP was first found at 4 h after transfection. The amount and intensity of EGFP increased gradually during the period of detection and got to the peak degree at 72 h, after that decreased slowly. EGFP was also seen in the second generation cells, but the intensity was relatively faint. The IGF-I concentration secreted into the supernatant was in accordance with the EGFP observed with the peak concentration at 34.75 ng/ml. The outcome of RT-PCR and immunohistochemistry was positive. The morphology of many stem cells was changed into triangular or irregular forms under the circumstance of the secreted hIGF-I. Percentage of stem cells in the S stage increased after transfection.

CONCLUSIONThe hIGF-I gene can be transfected efficiently and safely into BMSCs by FuGene 6, and the hIGF-I protein can be secreted into the supernatant in a relatively high level during a long period, therefore accelerate the proliferation and differentiation of the transfected cells.
