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.

OBJECTIVETo investigate the correlation among serum levels of manning-binding lectin (MBL), MBL-associated serine proteases-2 (MASP-2), complement Cand high-sensitive C reactive protein (HsCRP) in patients with rheumatoid arthritis (RA).

METHODSFasting venous blood were collected from 50 RA patients (25 in active stage and 25 in remission) and 40 healthy subjects for detecting serum levels of MBL, MASP-2, complement Cand HsCRP using enzyme-linked immunosorbent assay (ELISA) and immune turbidity assay.

RESULTSThe serum levels of MBL and MASP-2 were significantly lower and HsCRP level was significantly higher in patients with RA (in both acute stage and remission) than in the healthy control group (P<0.05), but complement Clevel was similar between the RA patients and control group. Bivariate Pearson correlation analysis showed that in RA patients, MBL was positively correlated with MASP-2 level (r=0.550, P=0.001) and negatively with HsCRP (r=-0.323, P=0.022) but not correlated with C(r=-0.022, P=0.882); MASP-2 was negatively correlated with HsCRP (r=0.453, P=0.453) and was not correlated with C(r=0.049, P=0.738). ROC curve analysis revealed the largest area under curve (AUC) of HsCRP (0.844, P=0.001) and smaller AUCs of MBL (0.025, P=0.001) and MASP-2 (0.266, P=0.001). HsCRP had a much higher sensitivity (84%) than MBL (10%) and MASP-2 (40%) in the diagnosis of RA.

CONCLUSIONIn RA patients, MBL and MASP-2 are negatively correlated with HsCRP level. Serum MBL and MASP-2 levels decrease with the progression of joint injury in RA patients, suggesting their involvement in the pathological process of RA; but due to their low sensitivity, they are not appropriate indicators for evaluating the disease activity of RA.

OBJECTIVETo study the effects of telmisartan on voltage dependant potassium channel (Kv) expression in lymphocytes from spontaneously hypertensive rat (SHR).

METHODSPeripheral blood was collected from male SHR aged 16 and 4 weeks. Peripheral lymphocytes were separated from heparinized whole blood by standard Ficoll-Hypaque density gradient centrifugation. The whole-cell Kv currents were recorded with patch-clamp technique in the absence and presence of telmisartan(10, 30, 100 µmol/L). Real-time PCR was used to determine Kv1.3 mRNA expression in lymphocytes.

RESULTS(1) The currents density of Kv was higher in lymphocytes from 16 weeks-old SHR [ (119.0 ± 9.6) pA/pF] than from 4 weeks-old SHR [(59.0 ± 7.2) pA/pF, P < 0.05]. (2) Currents density was positively correlated with systolic blood pressure in 16 weeks-old SHR (r = 0.837, P < 0.05). (3) The lymphocytes Kv 1.3 mRNA expression was significantly higher in 16-weeks-old SHR than in 4-weeks-old SHR (P < 0.05). (4) Telmisartan reduced the whole-cell Kv currents in a concentration-dependent manner (10.5 ± 3.4)% at 10 µmol/L, (45.8 ± 3.7)% at 30 µmol/L and (81.6 ± 4.2)% at 100 µmol/L, P < 0.01.

CONCLUSIONSThe lymphocyte Kv channel is upregulated in 16 weeks-old SHR suggesting a role of Kv in the pathophysiology of hypertension. Kv current in lymphocyte could be significantly blocked by telmisartan in a concentration dependent manner.

This study was aimed to explore the inhibitory effect of triptolide on proliferation and inducing apoptosis effect of K562/G01 cells and their possible mechanism. MTT assay was used to detect the effect of imatinib or triptolide alone and their combination on K562/G01 proliferation; the cell cycle, apoptosis rate, P-gp protein expression were detected by flow cytometry (FCM); the expression of P-gp was assessed by Western blot; the BCR/ABL gene expression was assayed by real time quantitative PCR. The results showed that triptolide could enhance the effect of imatinib on proliferation inhibition and apoptosis of K562/G01, arrested the cell cycle in G1 phase, down-regulated the expression of BCR/ABL gene and P-gp protein. It is concluded that triptolide induces K562/G01 cell proliferation inhibition and apoptosis, the mechanism may be related to cell cycle arrest, decrease of P-gp protein expression, inhibition of BCR/ABL gene expression.

OBJECTIVETo investigate the protective action of Epimedium against chemotherapy-induced damage to rat epididymides.

METHODSFifty 60-day-old male rats were divided into a control, a model and a treatment group. Procarbazine was injected into the abdominal cavity of the model rats at the dose of 30 mg/(kg x d). In addition to procarbazine, Epimedium was given intragastrically to the treatment group. The changes in the ultrastructure of the epididymis were observed after 10 and 20 days.

RESULTSElectron microscopy showed that the chemotherapy-induced damages to the epididymal epithelia mainly included cell swelling, local cavitation of mitochondria, tumor-like change in nucleoli, agglutination of marginal translocation of heterochromatin and cell apoptosis. The damage to the epithelial ultrastructure was slight in the treatment group as compared with the model rats. Chemotherapy significantly affected sperm concentration, sperm viability and sialic acid (SA), which were (15.59 +/- 4.01) x 10(6)/ml, (76.71 +/- 10.11)% and (19.38 +/- 9.34) g/mg prot in the model group in comparison with (10.63 +/- 3.82) x 10(6)/ml (P < 0.01), (60.03 +/- 7.54)% (P < 0.01) and (13.62 +/- 7.81) g/g prot (P < 0.05) in the control. Epimedium significantly increased sperm viability in the treatment group (60.03 +/- 7.54)% as compared with the model rats (69.90 +/- 12.58)% (P < 0.05).

CONCLUSIONEpimedium can lessen chemotherapy-induced damage to the epididymis and protect the reproductive function of rats.

The present study aimed to investigate the difference in the voltage dependent potassium channel (Kv) expression in lymphocytes between the spontaneously hypertensive rats (SHRs) and Wistar rats. Peripheral blood lymphocytes were collected from 10 male SHRs and 10 normotensive Wistar rats aged 16 weeks. First, by using the patch-clamp technique, Kv channel current was recorded in freshly isolated lymphocytes from SHRs and normotensive Wistar rats. Total RNAs were extracted from lymphocytes by using TRIzol reagent. Real-time PCR was used to determine the expression of Kv1.3 mRNA and Western blot technique was used to measure the expression of Kv1.3 protein in lymphocytes from SHRs and normotensive Wistar rats. The results showed that: (1) The current density of Kv channel in the step voltage of +60 mV was higher in lymphocytes from SHRs than that from the normotensive Wistar rats [(119+/-10) pA/pF vs (56+/-9) pA/pF, P<0.05]; (2) The level of Kv1.3 mRNA expression in lymphocytes from SHRs was significantly increased compared with that of the normotensive Wistar rats (0.0313+/-0.017 vs 0.0023+/-0.005, P<0.05); (3) The expression of Kv1.3 protein was significantly elevated in lymphocytes (1.02+/-0.04 vs 0.41+/-0.03, P<0.05) from SHRs compared with that of the normotensive Wistar rats. The results obtained demonstrate that the lymphocytes Kv channels are increased in SHR, and the Kv channel may be involved in activation of lymphocytes from SHR.

OBJECTIVETo evaluate the role of nutritional status on serum immunoglobulins, body weight and postoperative infectious-related complications in patients with Crohn's disease receiving perioperative parenteral nutrition (PN).

METHODS32 patients with Crohn's disease receiving perioperative parenteral nutrition in our department between 1984 and 1994 were enrolled in this survey. 16 patients with loss of body weight in the range of 15%-30% were assigned to the malnutrition group, the other 16 patients with normal weight or loss of body weight less than 15% to the control group. Serum IgM, IgG and IgA levels were measured before and after PN by enzyme-linked immunosorbent assays. Liver function, body weight changes and postoperative complications were also analyzed.

RESULTSIgM levels were elevated before PN in both groups [control group: (133 +/- 16) mg/dl, malnutrition group: (139 +/- 41) mg/dl; normal value: (110 +/- 35) mg/dl; P = 0.04], decreased to normal value [(105 +/- 29) mg/dl, P = 0.02] in the malnutrition group while having no obvious changes in the control group [(129 +/- 13) mg/dl, P = 0.34]. No significant changes in concentrations of IgG and IgA were found (P in the range of 0.20-0.57). The average weight gain was 1.862 kg in malnutrition group [before PN: (45.8 +/- 8.9) kg, after PN: (48.0 +/- 8.8) kg; P = 0.005] and no significant changes in the control group [before PN: (55.6 +/- 6.1) kg, after PN: (56.3 +/- 6.0) kg; P = 0.46]. There was an increase in infectious complications in the control group (control group: 4 cases, 25%, malnourished group: 2 cases, 12.5%; P = 0.13).

CONCLUSIONSPerioperative parenteral nutrition ameliorated the humoral immunity, increased the body weight in patients with obvious malnutrition, whereas it had little value for those without or with mild malnutrition.

Objective To investigate the correlation between isoniazid concentration in plasma and lymph node tissue of patients with lymph node tuberculosis,and to explore its clinical value.Methods The basic information of patients with lymph node tuberculosis in our hospital and venous blood samples and neck lymph node tissue samples at different time points were collected.UPLC-MS/MS method was established and isoniazid concentration in plasma and neck lymph node tissue samples was quantitatively detected,and the correlation between isoniazid concentration in plasma and lymph node tissue was analyzed.Results The linear range of isoniazid blood concentration and lymph node tissue concentration were 0.25-16 μg·mL-1(r=0.999 8)and 2-128 μg·g-1(r=0.998 8),respectively.The precision,accuracy,and matrix effect of each quality control sample met the requirements.Plasma isoniazid concentration and lymph node tissue isoniazid concentration were significantly correlated at 10 min(rs=0.501 1,P=0.001),30 min(rs=0.402 8,P=0.005)and 60 min(rs=0.614 6,P=0.001)after intravenous infusion of isoniazid.The ratio of lymph node tissue isoniazid concentration to plasma isoniazid concentration was 1.46(0.62,3.55)mL·g-1 at 10 min.At 30 min,the ratio was 5.25(4.61,11.61)mL·g-1.At 60 min,the ratio was 6.62(4.42,10.78)mL·g-1.Conclusion The established UPLC-MS/MS method has good specificity,high sensitivity,accurac and precision.Monitoring plasma isoniazid concentration provides a reference for the rational use of isoniazid in patients with lymphatic tuberculosis.

OBJECTIVETo evaluate the efficacy and safety of antifungal prophylaxis of itraconazole in patients with acute myeloid leukemia (AML) to probe the relationship of the antifungal effect and the adverse events with serum concentration.

METHODSFrom April 2009 to May 2011, a total of 310 courses from 112 patients referred to our institute were enrolled in this study; of them, 297 courses were eligible for analysis. Eligible cases were randomized into oral group and injection/oral group according to different chemotherapy of induction and consolidation. Blood samples were collected at different time points for measurements of serum itraconazole levels. The morbidity of IFI and the adverse events were analyzed.

RESULTSThe morbidities of IFI in injection/oral and oral groups were 10.1% and 20.9%, respectively (P=0.010). 7 and 9 cases in injection/oral and oral groups, respectively were withdrawn from the study because of adverse events, and the difference between these two groups was of no significance. Serum itraconazole levels of injection/oral and oral groups were 672(299-1097) μg/L and 534(210-936) μg/L, respectively (P<0.01).

CONCLUSIONAntifungal prophylaxis with itraconazole in AML patients was effective and safe. Prophylactic effect with injection/oral itraconazole was superior to oral itraconazole solution; moreover, prophylactic effect of itraconazole was highly correlated with its serum level.

OBJECTIVEThis study was aimed to observe the efficacy of autologous stem cell transplantation (ASCT) for adult patients with acute lymphoblastic leukemia (ALL), and investigate related prognostic factors.

METHODSA total of 86 adult ALL patients underwent ASCT in Institute of Hematology and Blood Disease Hospital from November 2001 to January 2012 were followed up. Clinical characteristics and outcomes of all patients were retrospectively analyzed. Survival and univariate prognosis were analyzed by the Kaplan-Meier method and multivariate analysis by COX regression model.

RESULTSOutcomes were assessed in 81 cases, including 47 standard-risk and 34 high-risk patients. 1-, 3-, 5-, and 10-year leukemia-free survival (LFS) of standard-risk patients were (82.3±5.7)%, (76.9±6.5)%, (74.1±6.8)%, (67.4±8.9)% respectively,and relapse rates (RR) were as of (13.6±5.2)%, (21.6±6.4)%, (24.5±6.8)%, (31.3±9.0)% respectively. 1-, 3-, 5-, and 10-year LFS of high-risk patients were (55.8±8.9)%, (39.8±9.3)%, (39.8±9.3)%, (39.8±9.3)% respectively, and relapse rates (RR) were (38.8±9.2)%, (56.4±10.0)%, (56.4±10.0)%, (56.4±10.0)% respectively. T-ALL, white blood cell count(WBC) more than 30×109/L when first visited, increased LDH, positive fusion gene of TCR and bone marrow transplantation were the adverse prognostic factors. Multivariate analysis showed bone marrow transplantation was an independent adverse prognostic factor.

CONCLUSIONASCT was a choice for adult ALL patients when suitable donors were unavailable.
