OBJECTIVETo explore the adjunctive therapeutic effects of acupuncture for leukopenia induced by chemotherapy. METHODS Eighty six cases with leukopenia after chemotherapy treatment were randomly divided into a granulocyte colony-stimulating factor (G-CSF) plus acupuncture (A) group and a G-CSF group, 43 cases in each group. After chemotherapy treatments, the patients of both groups were treated with G-CSF for 4 times, with acupuncture at Zhigou (TE 6), Quchi (LI 11), Hegu (LI 4), etc. added in the G-CSF plus A group, for an observaion cycle of 45 days. Their therapeutic effects on the 10th and 31st day and peripheral white blood cell (WBC) counts and neutrophilic granulocyte classification on the 10th, 17th, 24th, 45th day after treatment were compared.

RESULTSAfter they were treated on the 10th day, the effective rates were both 100.0% (both 43/43), and on the 31st day, the effective rate of 98.9% (42/43) in the G-CSF plus A group was higher than 91.1% (35/43) in the G-CSF group (P < 0.05). The WBC counts in the G-CSF plus acupuncture group were both higher than those in the G-CSF group on the 10th, 17th and 24th day after treatment (all P < 0.05). The ratios of mature neutrophilic granulocyte in the G-CSF plus A group were all higher than those in the G-CSF group at the same time (all P < 0.01).

CONCLUSIONAcupuncture can increase the therapeutic effect of G-CSF, delay the decrease of WBC after discontinuing G-CSF, promote the neutrophilic granulocyte differentiating forward to mature and it is better for improving leukopenia induced by chemotherapy.

Forest plays very important roles in global system with about 35% land area producing about 70% of total land net production. It is important to consider both elevated CO(2) concentrations and different soil moisture when the possible effects of elevated CO(2) concentration on trees are assessed. In this study, we grew Cinnamomum camphora seedlings under two CO(2) concentrations (350 micromol/mol and 500 micromol/mol) and three soil moisture levels [80%, 60% and 40% FWC (field water capacity)] to focus on the effects of exposure of trees to elevated CO(2) on underground and aboveground plant growth, and its dependence on soil moisture. The results indicated that high CO(2) concentration has no significant effects on shoot height but significantly impacts shoot weight and ratio of shoot weight to height under three soil moisture levels. The response of root growth to CO(2) enrichment is just reversed, there are obvious effects on root length growth, but no effects on root weight growth and ratio of root weight to length. The CO(2) enrichment decreased 20.42%, 32.78%, 20.59% of weight ratio of root to shoot under 40%, 60% and 80% FWC soil water conditions, respectively. And elevated CO(2) concentration significantly increased the water content in aboveground and underground parts. Then we concluded that high CO(2) concentration favours more tree aboveground biomass growth than underground biomass growth under favorable soil water conditions. And CO(2) enrichment enhanced lateral growth of shoot and vertical growth of root. The responses of plants to elevated CO(2) depend on soil water availability, and plants may benefit more from CO(2) enrichment with sufficient water supply.

AIMTo learn the condition of the memory and the visual space of the patient who has suffered from the infarction in basal ganglia region, and to analyze its impact on and the characteristics of the patients' cognition.

METHODSBy testing respectively on 21 subjects who were initially infarcted in basal ganglia with single focus on one side, and 21 healthy volunteers with corresponding age, gender and educational background with Rey-Osterrieth Complex Figure Scale (Rey), Clinical Memory Scale (CMS), Hospital Anxiety-Depression Scale (HAD), National Institute of Health Stroke Scale (NIHSS), Oxford Handicap Scale (OHS), Barthel Index (BI), and Aural Event Related Evoked Potential (AERP) as well.

RESULTSCompared with the control group, the patient group got higher scores of anxiety and depression in HAD), which showed absolutely statistical significance; they demonstrated longer reaction time in AERP, which also showed statistical significance; and in CMS. they displayed inferior performance in the free picture recall and the memory quotient (MQ), which again had statistical significance. However, compared with the control group, the patient group got scores with no significance in copy, immediate recall and delayed recall in Rey.

CONCLUSIONThe infarction in basal ganglia region with single focus on one side may impact on the patient's executive function, memory function and emotion. But no impact is showed on patient's visual space function.

OBJECTIVETo evaluate whether the D-3-phosphoglycerate dehydrogenase (Phgdh) correlative antibodies is crucial for AIH, we cloned Phgdh cDNA and constructed plasmid, then purified and identified the immunoreactivity of the recombinant protein, and established the enzyme linked immunosorbent assay (ELISA) to detect Phgdh autoantigen correlative antibodies in diagnosis of autoimmune hepatitis.

METHODSThe constructed plasmid was transformed into E. coli. BL21(D3). This fusion protein was purified by Ni-NTA chromatography and its immunoreactivity was identified by SDS-PAGE and Western blot. The ELISA with the fusion protein was established first, then, the Phgdh autoantigen correlative antibodies in serum of patients with AIH (65) and patients with PBC (122) as well as chronic hepatitis B (CHB) (56), chronic hepatitis C (CHC) (117), and normal controls (60) were detected.

RESULTSThe sequence of Phgdh autoantigen gene was the same as the sequence reported on the genebank. The fusion protein was found about 60kD strip on SDS-PAGE. Western blot analysis showed that the fusion protein had immunoreactivity. When analyzing the serum by ELISA, the immune reactivity to Phgdh was detected in 66.15% of patients with AIH, 21.42% of patients with PBC, 12.50% of patients with CHB, 6.83% of patients with CHC, and 3.30% of normal individuals. The differences of prevalence between AIH patients and healthy controls as well as other diseases were of statistical significance (P less than 0.01).

CONCLUSIONThe Phgdh cDNA is successfully cloned into E. coli BL21 (D3). The frequency of antibodies to Phgdh is much higher in patients with AIH than in patients with PBC, CHB, CHC and normal control. The antibodies to Phgdh may have utility in improved diagnosis of AIH.

OBJECTIVETo compare the differences in damage degree, healing time and healing process between two animal models of defection fracture and provide the research data for the establishment of a new animal model.

METHODSSixty male SPF Spragur-Dawley rats were divided randomly into control group, sawing group and drilling hole group, with 20 rats in each group. Animals of drilling hole group were treated with hone drill and made an 1 mm hole on tibial plateau animals of sawing group were treated with saw and made an 3 mm defection on tibial plateau; nothing to do in animals of control group. The rats were respectively killed at 2nd, 4th weeks after operation, bone density, bone ash quantity, contents of bone Ca, P were detected.

RESULTSAt the 2nd week after operation, bone density, bone ash quantity, contents of bone Ca, P in drilling hole group and sawing group were significantly lower than that of the control group (P < 0.05 or P < 0.01). Two animal models of drilling hole group and sawing group were similar in X-ray films and pathology investigations. At the 4th week after operation, there were no significant defference in bone density and bone ash quantity among three groups (P > 0.05). Rats of sawing group showed more poroma and inflammatory infiltration in histological examination.

CONCLUSIONDrilling hole method and sawing method could be used to make animal model of defection fracture, two methods showed similar damage degree, healing time and healing process, hut drilling hole method have advantages of simple operation, easily control damage degree and less inflammatory infiltration and bone disunion.
