Objective To explore the treatment effects of noninvasive positive-pressure ventilations (NIPPV) on severe bronchial asthma and nursing measures. Methods Forty patients with severe bronchial asthma were treated by NIPPV, and joint applications of PSV and PEEP model were undergone through selecting different pressure. Results Symptoms of thirty-eight patients remitted obviously, and two patients needed invasive mechanical ventilation. Effective rate is 95%. After treatment, the vital sign and arterial blood gas analysis of patients were improved significantly. The incidence of adverse reaction association with ventilation was low. Conclusions Through selecting suitable patients and strengthening care, NIPPV was an effective method to treat severe bronchial asthma.

Objective To investigate the function of myeloid dendritic cells (mDCs) from severe aplastic anemia ( SAA ) patients in stimulating allogeneic T lymphocytes proliferation in vitro and then explore the immunopathogenesis of SAA. Methods Twenty-five SAA patients ( 15 untreated and 10 recovered after immunosuppressive therapy) and 12 normal controls were enrolled in this study. Their mature mDCs were induced from their bone marrow monocytes with recombined human interleukin-4 ( rhIL-4) , recombined human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) and recombined human tumor necrosis factor (rhTNF) in vitro. Then mDCs were co-cultured with allogeneic lymphocytes (mixture lymphocyte reaction, MLR) at a ratio of 1: 100 or 1: 50. The growth rate of lymphocyte was measured with methyl thiazolyl tetrazolium ( MTT) colorimetry.The concentrations of interleukin( IL) -12 and inlerferon -y (IFNγ) in MLR supernatant were measured with EL1SA. The correlation between the growth rate and the concentration of IL-12 or IFNγ was analyzed. Results When mDCs and lymphocytes were co-cultured at the ratio of 1: 100, the growth rates of lymphocytes stimulated with mDCs from untreated, recovered SAA patients and controls were (219. 8 ±94. 0)% , (159. 1 ±66. 0)% and (160. 1 ±91. 9)% respectively. The concentrations of IL-12 in MLR supernatant were (8. 2 ± 3. 6) ng/L, (6. 5 ± 2. 8) ng/L and (6. 1 ± 2. 6) ng/L and the concentrations of IFNγ were (21. 8 ± 8. 7) ng/L, (25. 5 ± 9. 1) ng/L and (22. 6 ± 7. 8) ng/L respectively. All of them had no statistical differences among the three groups ( P > 0. 05 ). When mDCs and lymphocytes were co-cultured at the ratio of 1: 50, the growth rate of lymphocytes stimulated with mDCs from untreated patients was (322. 1 ± 171. 1)% , which was higher than that of recovered patients [ (180. 9 ±79. 1)% and controls (192. 3 ±91. 9)% ]. The concentrations of IL-12 in MLR supernatant in the three groups were (12.6 ±4.4) ng/L, (9.4 ±3.3) ng/L and (8.5 ±3.7) ng/L, and the concentrations of IFNγ were (32. 3 + 9. 2 ) ng/L, ( 27. 4 ± 6. 5) ng/L and (24. 4 ± 7. 4 ) ng/L Both of the values in untreated cases were higher than those of the recovered cases or controls (P < 0. 05 ) , but there were no statistical difference between the recovered and control groups ( P >0. 05 ). The concentration of IL-12 in MLR supernatant correlated positively with the growth rate of lymphocyte (r=0. 529,P <0. 01) and so did the concentration of IFNγ (r = 0. 381, P < 0. 05). Conclusion The function of mDCs to stimulate T lymphocytes proliferation in SAA was enhanced; it might play an important role in the immunopathogenesis of SAA.

This report overviewed the national endemic status of schistosomiasis in China in 2008. During the whole year of 2008, a total of 412 927 cases of schistosomiasis were estimated and 57 acute cases were reported, among which one acute case infected with Schistosoma mansoni was imported from overseas. The reduction rates of total cases and acute cases were 19.97% and 32.53% when comparing to those in 2007, respectively. A total of 21 222 advanced cases were treated in 2008 with an increase rate of 15.04% comparing with that in 2007. About 372 263. 11 hm~2 of areas infested with Oncomelania snails were found in 2008, and about 1 197. 89 hm~2 newly detected areas were found in non-infested areas with Oncomelania snails, in historical records. There were 1 468 669 head of the cattle with its infection rate of 1.34% in schistosomiasis transmission regions, with reduction rates of 1. 86% and 36.79% , respectively, comparing to those in 2007. However, cattle were still remaining as the main infectious source for the transmission of schistosomiasis. Six provinces including Jiangsu, Anhui, Jiangxi, Hubei, Hunan, and Yunnan reached the national criteria of infection control. Sichuan Province reached the national criteria of transmission control. The country achieved the mid-term goal of schistosomiasis control written in the document ofOutline of mid- and long-term national programme on control and prevention of schistosomiasis (2004 -2015).

Objective To evaluate the clinical efficacy of a stroke unit combined with community health services for treating stroke survivors. Methods A total of 120 stroke patients were randomly divided into a " stroke unit combined with community medicine" group ( combined group) , a stroke unit group and a general treatment group. Patients in the former 2 groups were treated in a hospital stroke unit during their hospitali-zation. The general treatment group was given conventional medical treatment. After discharge, the combined group continued to receive regular rehabilitation therapy and guidance in the form of community medical services, while the stroke unit group received follow-up only. Assessment was by means of Fugl-Meyer scores, the Barthel index and self-rating on a depression scale ( SDS). The patients were assessed at admission, on discharge and 3 months after discharge. Results There were no significant differences in average limb motor function, ability in the activities of daily living ( ADL) or depressive mood among the 3 groups on admission, but at discharge, limb motor function and ADL ability in the combined group and stroke unit groups were significantly superior to those in the general therapy group. Limb motor function and ADL ability in the combined and stroke unit groups had improved further 3 months after discharge, with more significant improvements in the combined group. No significant change in depression was observed in any group at discharge, but average depression scores in the combined and stroke unit groups improved significantly in the 3 months after discharge, and there was a statistically significant difference between the combined group and the general group. Conclusion Supplementing the work of a stroke unit with community health services significantly improves stroke patients' recovery of limb motor function and ADL ability.

OBJECTIVETo explore the expression of multidrug resistance gene 1 ( MDR1), glutathione-S-transferases-pi (GST-pi) in osteosarcoma and soft tissue sarcoma tissues from 34 patients and their correlation with chemotherapy resistance.

METHODSMDR1 and GST-pi expressions were analyzed by real-time fluorescence quantitative polymerase chain reaction (FQ-PCR) and flow cytometry (FCM) at mRNA and protein levels, respectively. Chemotherapy sensitivity on adriamycin, cisplatinum, fluorouracil, mitomycin C, dacarbazine, vincristine, methotrexate in tumor tissues were detected by MTT assay.

RESULTSThe nonsensitive rates on adriamycin, cisplatinum, fluorouracil, mitomycin C, dacarbazine, vincristine, methotrexate in tumor tissues were 41.18%, 17.7%, 47.1%, 50.0%, 76.5%, 61.8% and 52.9%, respectively. The expression of P-glycoprotein (P-gp) and GST-pi in tumor tissues was 1.54 and 2.58 (relative fluorescence intensity). Chi2 analysis showed that there was a positive correlation between P-gp expression and drug resistance on ADM, GST-pi expression and resistance on ADM, DDP and MMC (P < 0.05). There was not seen obvious correlation between expression of MDR1, GST-pi and age, gender, pathological type, tumor size in osteosarcoma and soft tissue sarcoma patients (P > 0.05). The expression of GST-pi was increased in patients receiving preoperative chemotherapy. The rate of postoperative recurrence was higher in patients with higher GST-pi expression level than those with lower GST-pi expression level before operation (P < 0.05).

CONCLUSIONIndividual differences exist in chemotherapy sensitivity and expression of MDR1 and GST-pi in osteosarcoma and soft tissue sarcomas patients. Chemotherapy can induce up-regulation of GST-pi protein expression. Primary high expression of GST-pi is the main mechanism of resistance of osteosarcoma and soft tissue sarcomas to chemotherapy and is related to poor prognosis.

BACKGROUNDRecent studies have suggested that susceptibility to major depressive disorder (MDD) might be related to the serotonin 1A receptor (5-HTR1A) C (-1019) G polymorphism. In this study, we aimed to assess the association between 5-HTR1A C (-1019) G polymorphism and MDD in the Northern Han ethnic group of China.

METHODSThe C (-1019) G of 5-HTR1A was detected with polymerase chain reaction (PCR) in 400 patients with MDD and 400 unrelated age- and sex-matched healthy control subjects. Association between the C (-1019) G and MDD was statistically analyzed.

RESULTSThere was a statistically significant difference between MDD patients and controls in both the genotype distribution (Chi(2) = 10.913, df = 2, P = 0.004) and the allele frequency (Chi(2) = 10.379, df = 1, P = 0.001), and a significant difference in the genotype distribution and the allele frequency was found both in the female subjects (Genotype distribution: Chi(2) = 15.406, df = 2, P = 0.000; allele frequency: Chi(2) = 15.552, df = 1, P = 0.000) and the late-onset subjects (Genotype distribution: Chi(2) = 7.771, df = 2, P = 0.021; allele frequency: Chi(2) = 8.007, df = 1, P = 0.005) in the two groups.

CONCLUSIONThese results suggest that 5-HTR1A C (-1019) G polymorphism is probably associated with MDD and it is likely to be the susceptible gene locus for the female and late-onset MDD.

OBJECTIVESTo explore the relationships between the peripheral blood levels of CD61, CD63, PAC-1 and the incidence of acute rejection and tubular necrosis after renal transplantation, and recovery of the graft function.

METHODSThe peripheral blood levels of CD61, CD63, and PAC-1 of 86 patients with uremia in different stages before and after transplantations were analyzed by flow cytometry. The patients were divided into three groups: (1) twenty-nine patients with normal grafts function, (2) hirty with acute rejection and (3) twenty-seven with acute tubular necrosis. The patients with acute rejection were randomly divided into treatment group with anticoagulants and cntrol group.

RESULTSThe peripheral blood levels of CD61, CD63 and PAC-1 significantly increased (P < 0.05) in the patients with acute rejection, in comparison with those with normal grafts function and those with acute tubular necrosis. The peripheral blood levels of CD61, CD63 and PAC-1 in patients with acute rejection in anticoagulants therapy was lower, recovery time of the grafts function was shorter, one-year survival rates of patients and grafts were higher, as compared with those of controls.

CONCLUSIONSThe patients with acute rejection have significantly high peripheral blood levels of CD61, CD63 and PAC-1 before transplantation, however, these values in patients with acute tubular necrosis are not high, this suggesting that acute rejection might relate to platelet activation, while acute tubular necrosis might not relate to it. After anticoagulants therapy in patients with acute rejection, the grafts function might recover faster and their one-year survival rates and grafts might be higher in those with CD61, CD63 and PAC-1 decreasing remarkably.

Objective To investigate the reliability and validity of the simplified Chinese version of Epworth sleepiness scale(ESS). Methods Five hundred and eighty-five patients with suspected obstructive sleep apnea hypopnea syndrome (OSAHS) and 103 OSAHS patients who underwent operations were included in this study. The ESS was filled before polysomnography (PSG) monitoring under the direction of professional technicians. The patients who underwent operations did both PSG and ESS tests more than 6 months after operation. Fifty-one patients who underwent PSG at our hospital from July to August, 2010 were chosen to assess the ESS test-retest reliability on two separate occasions at least more than one week. Results The total Cronbach's Alpha of ESS was 0. 814. The test-retest reliability of ESS total scores was 0.679 and for each item was from 0.473 to 0.698 ( P ＜ 0.01 ). Split-half reliability was 0.817 ( P ＜ 0.01 ). In the analysis of discriminant validity with apnea hypopnea index (AHI), the ESS total scores and each item's scores had significant differences in severity in OSAHS patients and simple snoring patients( P ＜ 0.05 ), and this was also true in different degrees of lowest saturation of arterial oxygen ( LSaO2 ) patients and normal LSaO2 patients(P＜0.05). The factor analysis of construct validity showed that 4 factors were extracted.The cumulative proportion was 74.270%. The loading was higher than 0. 4 among every item. The correlation coefficiency of overall ESS scores and each item's scores was relatively high except the last item.The ESS had low consistency with clinical diagnosis(κ =0.099,P ＜0.01 ) and the predictive validity was not good (r =0.138, P ＜0.01 ). As for 103 patients who had operations, the initial assessment of total ESS scores were 15.0[10;20] ( M[P25 ;P75] ) ,and improved to 4[1 ;6] after operation. The patients who got effective results had significant difference in the total ESS scores before and after operation ( Z = - 7.528,P＜0.01) ,so was the patients who got ineffective results(Z= -4.382, P＜0.01) . Conclusions The simplified Chinese version of ESS had a good reliability and validity. It can be used to evaluate the chance of dozing in the daytime.

OBJECTIVETo compare the clinical features of children with different clinical forms of congenital hepatic fibrosis (CHF), and provides a description of the characteristics of childhood CHF.

METHODSSixty children with CHF between January 2002 and June 2015 were enrolled, including 26 children with portal hypertensive CHF (PH CHF), 3 children with cholangitic CHF, 30 children with combined portal hypertensive and cholangitic CHF (mixed CHF), and 1 child with latent forms of CHF. The medical data of 26 children with PH CHF and 30 children with mixed CHF, including gender, age, clinical manifestations, physical signs, laboratory tests and imaging characteristics, were retrospectively studied.

RESULTSFever, jaundice and hepatomegaly were more frequently noted in children with mixed CHF than in those with PH CHF (P<0.05). Splenomegaly and liver cirrhosis occurred more often in children with CHF, but there was no significant difference in the incidences of splenomegaly and liver cirrhosis between the children with PH CHF and mixed CHF. The plasma prothrombin activity, white blood cell counts, platelet counts, mean platelet volume, serum levels of alanine transaminase, aspartate transaminase, alkaline phosphatase, γ-glutamyl transferase, leucine aminopeptidase, and total bile acids in children with mixed CHF were higher than in those with PH CHF (P<0.05). The decreased international normalized ratio and lower serum albumin levels were more frequently observed in children with mixed CHF than in those with PH CHF (P<0.05).

CONCLUSIONSPH and mixed CHF are common forms in childhood CHF. The children with the two forms of PH usually manifest portal hypertension such as cirrhosis and hepatosplenomegaly. The liver damage may be common in children with mixed CHF.
