Objective To observe the clinical efficacy of balance acupuncture predominantly by puncturing Jiaji points (EX-B2) from C4 to T1and from T12 to L1in treating hemiplegic balance disturbance after cerebral stroke. Method A total of 180 hemiplegia patients were randomized into 3 groups, 60 cases in balance acupuncture group, 60 cases in ordinary acupuncture group, and 60 cases in basic control group. After 1-month treatment and 3 months after the treatment, the motor function (Fugl-Meyer Assessment, FMA), balance function (Berg Balance Scale, BBS; Timed Up and Go Test, TUGT), and activities of daily living (ADL) (Barthel Index, BI) were observed.Result After 1-month treatment and 3 months after the treatment, limb function, balance ability and ADL were significantly different from those before the treatment in balance acupuncture group (P<0.01); after 1-month treatment, limb function in balance acupuncture group was significantly different from that in basic control group (P<0.05), and the differences were more statistically significant in comparing the rest indexes between the two groups (P<0.01); there were significant differences between ordinary acupuncture group and basic control group (P<0.05). Three months after the treatment, there was a significant difference in comparing balance function between balance acupuncture group and basic control group (P<0.05), and the differences were more statistically significant in comparing the rest indexes between the two groups (P<0.01), there was no significant difference in comparing balance function between ordinary acupuncture group and basic control group (P>0.05).Conclusion In combination with basic treatment, balance acupuncture works better than ordinary acupuncture and basic control in improving limb function, ADL and balance function of hemiplegia patients.

OBJECTIVETo analyze the clinical characteristics of plastic bronchitis associated with 2009 influenza A virus (H1N1) infection.

METHODA retrospective investigation of the clinical manifestation, bronchoscopy, and the histology of the cast, clinical course and outcome of 8 children with plastic bronchitis associated with influenza A virus (H1N1) infection during winter of 2009 and 2010 was performed.

RESULTAll 8 cases were boys, the range of age was 3 to 6 years. Five cases occurred in 2009 winter, accounting for 3.3% (5/150) of hospitalized children with influenza A (H1N1) infection; 3 cases occurred in 2010 winter, accounting for 15.8% (3/19) of hospitalized children with influenza A (H1N1) infection. Two patients had an underlying chronic disease, 1 had asthma, and the other had allergic rhinitis and atopic dermatitis. All the 8 cases had fever, cough and sputum; 2 had wheezing; 5 had respiratory distress. All 8 cases were diagnosed as influenza A virus (H1N1) infection complicated with pneumonia, of whom 5 patients had atelectasis, 2 had pneumothorax, 1 had pneumomediastinum, 1 had parapneumonic effusion, 2 patients were suspected of foreign body aspiration. Seven cases were admitted to an ICU, 5 patients developed respiratory failure, and 3 patients required mechanical ventilation. Flexible bronchoscopy and bronchial lavage was performed in all cases and showed bronchial cast. Histological examination of the bronchial cast revealed a fibrinous material containing large quantity of eosinophils, neutrophils, and lymphocytes in 7 patients, fibrinous material and necrotic material without inflammatory cells in 1 patient. After the bronchial cast was removed, all patients were improved greatly, no patients died.

CONCLUSIONPlastic bronchitis is a life-threatening complication associated with 2009 influenza A (H1N1) virus infection in children. In children with rapid and progressive respiratory distress with lung atelectasis or consolidation on chest radiograph, plastic bronchitis should be considered. Bronchoscopic extraction of casts should be carried out early.

OBJECTIVETo study the epidemiologic characteristics of hand-foot-mouth disease (HFMD) in Guiyang between 2008 and 2010.

METHODSThe epidemiologic characteristics of HFMD were analyzed by descriptive statistical methods based on the data from the China Information System for Disease Control and Prevention.

RESULTSA total of 27383 cases of HFMD were recorded in Guiyang between 2008 and 2010. The incidence of HFMD increased from 66.4439/100000 in 2008 to 163.9276/100000 in 2009 and 471.5515/100000 in 2010 (P<0.01). The mortality rate was 0.1026/100000 in 2010, which was significantly lower than in 2009 (0.2821/100000) (P<0.05). HFMD occurrence showed seasonality and reached a peak between April and June. HFMD cases were commonly noted in children under 5 years old, and especially in children under 3 years old. The main detected pathogen was human enterovirus 71 (EV17) in 2009. Whereas in 2010 the disease was mainly caused by CoxA16 and other intestinal viruses.

CONCLUSIONSThe incidence of HFMD in Guiyang increased year by year from 2008 to 2010, but the mortality rate decreased year by year. HFMD occurrence showed an obvious seasonality. HFMD was common in children under the age of five. The main pathogens of this disease included EV17, CoxA16 and other intestinal viruses.

This study was purposed to investigate the expression of Btk and NFκB in acute myeloid leukemia (AML) cells and its significance. Bone marrow mononuclear cell specimens were taken from 14 AML patients who were in new diagnosis and complete remission respectively, the expressions of Btk and NFκB at mRNA and protein levels were detected by RT-PCR and Western blot, respectively. The results showed that Btk and NFκB expressed in all the samples at RNA and protein levels. At protein level, Btk and NFκB expressions were higher in the cells from newly diagnosed AML patients than that in the cells from patients in complete remission stage (P < 0.05). It is concluded that Btk and NFκB may play an important role in the development and progression of AML, they may be used as potential therapeutic targets of AML and used in predicting the prognosis.

This study was aimed to investigate the effect of Btk inhibitor PCI-32765 and the proteasome inhibitor bortezomib on Raji and Ramos cell proliferation, apoptosis, and its mechanisms. Raji and Ramos cells were treated with PCI-32765 and bortezomib alone and/or their combination. The cell proliferation and apoptosis were detected by CCK-8 and flow cytometry respectively, the expression level of Btk, NFκB, c-IAP1, Bcl-xL and caspase-3 protein were measured by Western blot. The results indicated that: (1) after Raji and Ramos cells were treated with PCI-32765 (0.5, 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 µmol/L) alone and bortezomib (10, 20, 30, 40, 50, 60, 80 nmol/L) alone and their combination for 48 h, the cell proliferation and vitality were inhibited in a dose-dependent manner and both had synergistic effect; (2) Raji and Ramos cells were treated with PCI-32765 (2.0 µmol/L) and bortezomib (20 nmol/L) alone and their combination for 8, 12, 24, 36, 48 and 72 h, the cell proliferation and vitality were inhibited in a time-dependent manner, the two drugs displayed a synergistic effects; (3) the Raji and Ramos cells were treated with PCI-32765 (2.0 µmol/L) and bortezomib (20 nmol/L) alone and their combination for 48 h, all these treatments could induce significant apoptosis of Raji and Ramos cells.In Raji cell experiment, the cell apoptosis rate in the control group, PCI-32765 group, bortezomib group and PCI-32765 and bortezomib combination group were 10.34 ± 0.53%, 24.26 ± 0.91%, 43.66 ± 1.08% and 74.06 ± 0.72% respectively, and the differences was statistically significant among the different groups (P < 0.05). In Ramos cell experiment, the cell apoptosis rate in the control group, PCI-32765 group, bortezomib group and PCI-32765 and bortezomib combination group are 15.16 ± 1.49%, 71.36 ± 0.82%, 75.32 ± 2.36% and 84.30 ± 0.91% respectively, the differences was statistically significant among the different groups (P < 0.05); (4) PCI-32765 and bortezomib could inhibit the expression level of intracellular Btk, NFκB, Bcl-xl and c-IAP1 proteins, but up-regulate the expression level of caspase-3. It is concluded that PCI-32765 and bortezomib can synergistically inhibit the proliferation and induce apoptosis of Raji and Ramos cells, the mechanism may be associated with inhibition of Btk and NFκB activity, down-regulation of anti-apoptotic proteins expression, such as Bcl-xl and c-IAP1, and increase of caspase-3 expression.

The aim of this study was to investigate the effects of Celecoxib on the proliferation, apoptosis, cell cycle and CD117 expression of K562 cells, and to explore its synergistic effect with IFN-alpha. K562 cells were treated with IFN-alpha, Celecoxib and combination of Celecoxib with IFN-alpha at different concentrations. The inhibitory effect of Celecoxib and IFN-alpha on cell proliferation was detected with MTT assay, the cell apoptosis, cell cycle and CD117 expression were determined by morphology observation and flow cytometry. The results showed that the Celecoxib inhibited proliferation of K562 cells in concentration-dependent manner (r=-0.91). After culture of K562 cells for 72 hours, the rates of K562 cell proliferation in control group, IFN-alpha group, Celecoxib group and IFN-alpha-combined Celecoxib group were (96.1+/-0.5)%, (90.2+/-0.4)%, (57.2+/-0.9)% and (21.9+/-0.3)% respectively. The cell apoptosis rates in 4 groups were (5.5+/-0.8)%, (6.3+/-0.6)%, (26.4+/-3.9)% and (57.3+/-4.5)% respectively. The CD117 expression rates in 4 groups were 54.7%, 10.5%, 36.3% and 7.3% respectively. Combination of Celecoxib with IFN-alpha might block K562 cells in G0/G1 phase. In conclusion, Celecoxib and IFN-alpha both may inhibit K562 cell proliferation, induce apoptosis, reduce CD117 expression and produce G0/G1 phase block to various degree and the two drugs have a synergistic effect.

OBJECTIVETo investigate the association of changes in immune function with enterovirus 71 (EV71) cases with different severity of the disease.

METHODForty-six EV71-infected patients and 12 age-matched healthy children were enrolled in this study. The patients were divided into four groups according to critical degree of enterovirus 71 infection: hand-foot-and-mouth disease (HFMD); central nervous system disease (CNSD); autonomic nervous system dysregulation (ANSD) and pulmonary edema (PE). We analyzed CD14+ monocyte HLA-DR expression, lymphocyte immunophenotypes, the proportion of CD4+CD25+ Foxp3high regulatory T cells (Treg cells) and Th17 cells, cytokines (IL-1beta, TNF-alpha, IL-10, TGF-beta, IL-6, IL-17A), evaluated the mRNA levels of Foxp3 and ROR-gammat, and serum immunoglobulin and complements.

RESULT(1) Serum concentrations of IL-1beta and TNF-alpha elevated in mild cases, while declined in severe cases, and were lower in PE group (P<0.05). Serum concentrations of IL-10 and IL-10/TNF-alpha ratio gradually raised with the aggravation of the disease, and higher in PE group (P<0.05). (2) Circulating CD14+ monocyte HLA-DR expression, CD3+T cells, CD4+T cells, CD8+T cells, and NK cells gradually decreased, and lower in PE group (P<0.05). There was no significant difference in B cells, immunoglobulin and complement among the four groups. (3) The proportion of CD4+CD25+ Foxp3high Treg cells, mRNA level of Foxp, and serum concentrations of TGF-beta gradually decreased with the aggravation of the disease, while the proportion of Th17 cells, serum concentrations of IL-17A, mRNA level of ROR-gammat, and IL-6 gradually increased with the aggravation.

CONCLUSIONImmune function changed with different illness phases. The mild cases presented systemic inflammatory response syndrome status, while critically ill cases presented compensatory anti-inflammatory response syndrome or mixed antagonist response status. Immunoregulatory treatment of patients with EV71 infection should emphasize different methods at different stage and individualization.

The study was aimed to investigate the synergistically effect of interferon-α (IFN-α) and homoharringtonine (HHT) on the proliferation, apoptosis, cell cycle of K562 cells and the expression of β-catenin. The proliferation, apoptosis, cell cycle and β-catenin mRNA expression of K562 cells treated with IFN-α and/or HHT were assayed with MTT, flow cytometry or RT-PCR respectively. The results showed that HHT alone, but not IFN-α alone, displayed a proliferation inhibition, apoptosis induction, G(0)/G(1) phase block and down-regulation of β-catenin expression in K562 cells with concentration- and time-dependent manners. The expression level of β-catenin mRNA after being treated with HHT was 0.5576 ± 0.0373, which were lower than that in control group (0.9369 ± 0.0142). The down-regulation of β-catenin expression in group of IFN-α combined with HHT was higher significantly than that in HHT group (0.3737 ± 0.0529 vs 0.5576 ± 0.0373, P < 0.05). Otherwise, HHT combined with IFN-α did not demonstrate obvious toxicologic effect on bone marrow mononuclear cells. It is concluded that IFN-α combined with HHT can enhance the cytotoxic effect of HHT on K562 cells, which may be associated with down-regulation of β-catenin expression.

This study was aimed to investigate the effect of homoharringtonine (HHT) on K562 cell proliferation, apoptosis and expression of BCL-2 and NF-κB proteins. The cells proliferation was assayed with MTT method, the cell apoptosis, cell cycle and BCL-2 expression were analyzed with flow cytometry, NF-κB protein expression was detected with Western blot. The results showed that HHT concentration-dependently inhibited proliferation of K562 cells, the IC50 at 48 h was 43.89 ng/ml. Treated with HHT 10 ng/ml for 48 h, K562 cell apoptosis significantly increased, cell cycle was blocked at G0/G1, the expression level of BCL-2 and NF-κB proteins was lower than that in control group (P < 0.05). It is concluded that HHT may inhibit the proliferation of K562 cells, and down-regulating expression levels of BCL-2 and NF-κB may be one of its anti-CML mechanisms.
