OBJECTIVETo compare the therapeutic differences among scalp acupuncture combined with auricular point sticking, body acupuncture and western medication for treatment of vascular dementia (VD).

METHODSNinety cases were randomly divided into a combined therapy group (31 cases), a body acupuncture group (29 cases) and a western medication group (30 cases). The combined therapy group was treated with scalp acupuncture at forehead middle line, parieral middle line, temporal front line and temporal rear line as well as auricular point sticking at naogan (AT3,41), shen (CO10), shenmen (TF4), zhen (AT3), once a day; the body acupuncture group was treated with acupuncture at Baihui (GV 20), Fengchi (GB 20), Zusanli (ST 36) and so on, once a day; the western medication group was treated with oral administration of aniracetam tablets, 0.2 g per time, twice a day. Fourteen days were considered as a treatment course, and totally 3 courses were required. The mini-mental state examination (MMSE) and activities of daily living (ADL) were applied to assess the changes of cognitive behavior ability before and after treatment among three groups. Also the efficacy among three groups were compared.

RESULTSOne case dropped out in the body acupuncture group and western medication group, respectively. The total effective rate was 90.334 (28/31) in the combined therapy group, which was superior to 85.734 (24/28) in the body acupuncture group and 79.3% (23/29) in the western medication group (both P < 0.05). After the treatment, the scores of MMSE and ADL were all improved among three groups, which was the most significant in the combined therapy group (MMSE: 23.32 +/- 4.45 vs 21.23 +/- 4.13, P < 0.05; 23.32 +/- 4.45 vs 20.41 +/- 4. 01, P < 0.01; ADL: 53.18 +/- 21.55 vs 51.92 +/- 20.42, P < 0.05; 53.18 +/- 21.55 vs 49.42 +/- 19.43, P < 0.01).

CONCLUSIONThe scalp acupuncture combined with auricular point sticking could improve the clinical symptoms and cognitive behavior ability in patients with vascular dementia, which has superior total efficacy to body acupuncture and western medication aniracetam tablets.

Objective To determine the clinical significance of measuring the levels of 25-(OH) vitamin D3 [(25-(OH) D3)],immune globulins and serum alkaline phosphatase(AKP) in children with recurrent community-acquired pneumonia(CAP).Methods Serum samples were collected in children with recurrent CAP (recur-rent CAP group,n =38),first CAP (first CAP group,n =123),and age matched normal children (heath control group,n =39).The 25-(OH) D3 level,IgG,IgM,IgA and AKP levels were measured.Results The serum 25-(OH)D3 concentration of the recurrent CAP group was (47.87 ± 2.28)nmol/L,that of the first CAP group was (84.43 ± 4.12) nmol/L,and that of the heath control group was (91.2 ± 7.85) nmol/L,the differences among the three groups were statistically significant (t =3.716,8.881,all P ＜0.05).The differences of the serum IgA concen tration among the three groups had statistically significant differences (t =4.596,5.319,9.230,all P ＜ 0.05).But the serum IgG concentration among the three groups had no statistically significant differences(t =1.115,1.887,1.090,all P ＞ 0.05).The serum IgM concentration among the three groups had no statistically significant differences (t =0.804,0.942,0.918,all P ＞ 0.05).The serum AKP concentration among the three groups had no statistically signifi cant differences(t =0.277,0.661,0.866,all P ＞ 0.05).The serum 25-(OH) D3 levels in 161 cases of CAP patients were not correlated to any of the levels of IgM,IgG,IgA,or AKP.Conclusion The levels of 25-(OH) D3 and IgA are significantly lower in children with recurrent CAP,indicating that vitamin D deficiency may play a role in the pathogenesis of recurrent CAP.Prophylactic use of vitamin D supplementation may improve the immune function and reduce the development of recurrent CAP in children.

OBJECTIVETo explore the effects of trichloroethylene (TCE) and its by-products (trichloroacetic acid, TCA; dichloroacetic acid, DCA) on the normal human peripheral blood lymphocyte and the role of DCA in dermatitis medicamentosa- like induced by trichloroethylene (DMLT).

METHODSLymphocyte was isolated from peripheral venous blood, and cytotoxicity of human lymphocytes treated with different concentrations (0.02 approximately 30.00 mmol/L) of DCA was determined at indicated times (2 h and 4 h) based on the MTS assay. Action of DCA on cell viability, membrane integrity was assessed by neutral red uptake (NRU) assay and lactate dehydrogenase (LDH) release test and measurement of superoxide dismutase (SOD) activity. Fluorescence quantitative reverse transcription polymerase chain reaction (FQ-RT-PCR) was employed for detection and quantization of the chemokine receptor CXCR2 and chemokine receptor CXCR3 mRNA in peripheral blood lymphocyte treated with different concentrations of DCA.

RESULTSDCA had a more vital effect on peripheral blood lymphocyte than TCE and TCA. A concentration-dependent release of LDH was observed at 4 h after cells were exposed to different doses of DCA (0.88, 1.75, 3.50 and 7.00 mmol/L) (P < 0.05), and DCA also caused an inhibition of SOD activity in a concentration-dependent manner (P < 0.05). The results of FQ- RT- PCR indicated that CXCR2 and CXCR3 mRNA were all over- expression. At 48 h after the DCA of 0.5 mmol/L and 10.00 mmol/L was used, CXCR2 and CXCR3 mRNA were 10.34, 5.66-fold and 19.43, 8.75-fold of those in the control group (P < 0.01).

CONCLUSIONDCA is of a great cytotoxicity and may be one of crucial evocators on DMLT.
