OBJECTIVETo observe the effect of Shen warming Pi strengthening method on expressions of serum T cell subsets (C045+%, C03+%, and C04 +/COB+) in diarrhea-predominant irritable bowel syndrome (IBS-0) rats. Methods An IBS-0 rat model was established referring to AL-Chaer's modeling method combined with tail clamp and intragastric administration of sanna leaf. After modeling 30 SO rats were randomly divided into 6 groups according to random digit table, i.e., the model group, the high, middle, low dose Wenshen Jianpi Recipe (WJR) groups, and the Sishen Pill control group, 6 in each group. A normal control group consisting of 6 SO rats were also set up. Rats in high, middle, low dose WJ R groups were administered by gastrogavage with boil-free WJ R at the daily dose of 3. 100, 1. 550, 0. 775 g/kg, respectively. Rats in the Sis hen Pill control group were administered by gastrogavage with boil-free Sis hen Pill at the daily dose of 0. 736 g/kg. Equal volume of normal saline was given by gastrogavage to rats in the model group and the normal control group. All medication lasted for 2 successive weeks. Rats' general state, expressions of T cell subsets (CD45+%, CD3+%, and CD4+ /CDB+) changes were observed.

RESULTSCompared with the normal control group, expressions of CD45+% and CD3+% increased, but CD4+ /CDB+ decreased with statistical difference (P < 0. 05). Compared with the model group, expressions of CD45+% and CD3+% decreased, but CD4+ ICDB+ increased with statistical difference in high, middle, low dose WJR groups, and the Sis hen Pill control group (P <0. 05). Compared with the Sis hen Pill control group, there was statistical difference in all indices except CD45+ value in the low dose SWPSM group (P <0. 05). Compared with the low dose WJ R group, the expression of CD3+% decreased in high and middle dose WJR groups, and the Sis hen Pill control group; CD4+ /CD8+ increased in the Sishen Pill control group and the high dose SWPSM group (all P < 0. 05).

CONCLUSIONSWJR showed better treatment effect. The mechanism of Shen warming Pi strengthening method might be achieved by regulating expressions of CD45+% and CD3+%, and CD4+ /CD8+ ratios.

OBJECTIVEIBS-D rat model was established to assess the effect of Shen warming Pi strengthening method (SWPSM) for intervening diarrhea-predominant irritable bowel syndrome (IBS-D) by observing rats' general state, stool properties, AWR ranking, and histopathological changes.

METHODSTotally 72 rats were randomly divided into 6 groups, i.e. the normal group, the model group, the high, middle, low dose SWPSM groups, and the control group, 12 in each group. The IBS-D rat model was successfully established referring to AL-Chaer ED's modeling method. After modeling high, middle, and low dose SWPS Recipe boil-free granules were given by gastrogavage to rats in corresponding treatment groups. Sishen Pill boil-free granule was given by gastrogavage to those in the control group. Equal volume of normal saline was given by gastrogavage to rats in the model group. The medication lasted for 2 weeks. Rats' general state, stool properties, abdominal withdrawal reflex (AWR) ranking, and histopathological changes were observed.

RESULTSAfter treatment, the general state of all rats got im- provement to various degrees. The improvement in the high and middle dose SWPS Recipe groups were superior to that in the low dose SWPS Recipe group and the control group (P < 0.05). There was no statistical difference in the growth rate between after and before treatment in each group (P > 0.05). Compared with the model group and the low dose SWPS Recipe group, the defecation amount within 4 h was less in the high and middle dose SWPS Recipe groups and the control group (P < 0.05). The Bristol ranking score, average ranking of loose stool, ratio of dry stool and wet stool were lower in the high and middle dose SWPS Recipe groups than in the control group and the low dose SWPS Recipe group (P < 0.05). The AWR ranking score was lower in the high and middle dose SWPS Recipe groups than in the control group when the volume of balloon dilation was 1.5 mL. There was no organic change of histological or morphological observation.

CONCLUSIONSHigh sensitive IBS-D model was proved to be reliable. SWPSM could reduce the quantity of stools, lower Bristol ranking score, average ranking of loose stools as well as ratios of dry stool and wet stool, contributing to reducing the high sensitivity of rats' visceral organs to some extent.

This study is to establish the fingerprint for Phyllanthus emblica and their tannin parts from different habitats by HPLC for its quality control. The determination was carried out on a Diamonsil C18 (4.6 mm x 250 mm, 5 microm) column, with methanol-0.2% glacial acetic acid as mobile phase with gradient elution at a flow rate of 1 mL x min(-1). The temperature was maintained at 30 degrees C and the detected wavelength is 260 nm, Thirteen chromatographic peaks were extracted as the common peaks of the fingerprint of P. emblica, and eleven as the common peaks of P. emblica tannin parts, and five peaks were identified by comparing with referent samples. The fingerprints of 8 samples were compared and classified by similarity evaluation, cluster analysis and principal component analysis (PCA). The similarity degrees of eight P. emblica were between 0.763 and 0.993, while tannin parts were between 0.903 and 0.991. All the samples of P. emblica and their tannin parts were classified into 3 categories. The method was so highly reproducible, simple and reliable that it could provide basis for quality control and evaluation of P. emblica from different habitats.

OBJECTIVETo investigate the effect and regulation of extracellular signal-regulated kinase (ERK1/2) signaling pathway on the expression of transforming growth factor-beta1 (TGF-beta1) in human embryonic lung fibroblasts induced by SiO2.

METHODSHuman alveolar macrophages were collected from a silicotic patient by bronchoalveolar lavage and in the presence or absence of SiO2 (50 ug/ml) exposition for 18h, and then the conditioned supernatants were used to incubate HELF. The expressions of TGF-beta1, of the HELF acted with the conditioned AM supernatant fluid were detected with the immunocytochemistry method after treatment with PD98059 of inhibitor of ERK.

RESULTSThe expression of TGF-beta1 in HELF of the SiO2 treatment group (OD value is 0.322 7 +/- 0.023 8) exceed blank group (OD value is 0.163 7 +/- 0.019 6) and AM control group (OD value is 0.240 6 +/- 0.022 5) by the immunocytochemistry method. But the expression of TGF-beta1 had reduction in some extent in the PD98059 intervention group (OD value is 0.271 1 +/- 0.022 9). The values were statistically different (P < 0.05).

CONCLUSIONERK inhibitor PD98059 have inhibition effect on the expression of transforming growth factor-beta1 and expression of cytokine of human embryonic lung fibroblasts stimulated by SiO2. The study indicate that the proliferation and collagen production of HELF activated by SiO2 are mediated by ERK/MAPK signal pathway in some extent. PD98059 may antagonizes silica-induced lung fibrosis by inhibiting the expression of transforming growth factor-beta1.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a serious chronic condition with a global impact. Symptoms of COPD include progressive dyspnea, breathlessness, cough, and sputum production, which have a considerable impact on the lives of patients. In addition to the human cost of living with COPD and the resulting death, COPD entails a huge economic burden on the Chinese population, with patients spending up to one-third of the average family income on COPD management in some regions is clinically beneficial to adopt preventable measures via prudent COPD care utilization, monetary costs, and hospitalizations. METHODS: Toward this end, this study compared the relative effectiveness of six indices in predicting patient healthcare utilization, cost of care, and patient health outcome. The six assessment systems evaluated included the three multidimensional Body mass index, Obstruction, Dyspnea, Exercise capacity index, Dyspnea, Obstruction, Smoking, Exacerbation (DOSE) index, and COPD Assessment Test index, or the unidimensional measures that best predict the future of patient healthcare utilization, cost of care, and patient health outcome among Chinese COPD patients. RESULTS: Multiple linear regression models were created for each healthcare utilization, cost, and outcome including a single COPD index and the same group of demographic variables for each of the outcomes. CONCLUSION: We conclude that the DOSE index facilitates the prediction of patient healthcare utilization, disease expenditure, and negative clinical outcomes. Our study indicates that the DOSE index has a potential role beyond clinical predictions.

Objective To explore the nursing risk and management of the gerontal patient underwent operation of total knee replacement in perioperative period, and decrease the nursing risk. Methods 110 gerontal patients underwent operation of total knee replacement were divided into the experiment group and the control group according to the operation time. Patients in control group were given routine nursing cares and the ones in experiment group received nursing risk interventions based on the risk procedure management. Results The two groups had obvious difference in the nursing defect rates ( x2 = 4.21, P ＜ 0. 05 ), the degree of satisfaction (t =11.78,P ＜0. 01 ), the cost of HSS (t = 20.09,P＜0.01), and the rate of operation-correlated complications (t = 5. 30, P ＜0.01), average stay in hospital (t =8.01, P ＜0. 01 ), and the qualified rate of nursing cases (t =7. 70, P ＜ 0. 01 ) one day before leaving the hospital. Conclusions Risk procedure management in the gerontal patients underwent operation of total knee replacement in perioperative period could reduce the occurrence of nursing faults, the complications after operation and the length of stay, and raise the satisfaction degree, the function of knee joints and the qualified rate of nursing cases.

OBJECTIVETo investigate the value of multiplex fluorescence in situ hybridization (FISH) in the detection of complex karyotypic abnormalities of acute myeloid leukemia (AML).

METHODSMultiplex FISH was used in combination with conventional cytogenetics (CC) and interphase FISH to study 14 cases of AML with complex karyotypic abnormalities.

RESULTSIn the 14 cases of AML studied, conventional cytogenetics detected 23 numerical and 56 structural chromosome abnormalities. Among them 4 gained whole chromosome and 4 lost whole chromosome which were confirmed by multiplex FISH. Twelve chromosome losses detected by CC were revised as derivative chromosomes resulted from various structural aberrations, and 26 derivative and 19 marker chromosomes were characterized precisely by multiplex FISH. Most of them were resulted from unbalanced translocations, including 2 complex 8; 21 translocations, which have not been reported previously: t (8; 21), der (8) t (8; 21) (8pter --> 8q22::21q22 --> 21qter), der (21) t (8; 21; 8) (8qter --> 8q22:: 21p13 --> 21q22::8q22 --> 8qter) and t (21; 8; 18; 1), der (8) t (8; 21) (8pter --> 8q22:: 21q22 --> 21qter), der (21) t (21; 8; 18; 1) (21p13 --> 21q22?::8q22 --> 8q24 ?:: 18??::1q??q??). The complex karyotypic abnormalities involved nearly all chromosomes, of which the chromosomes 17, 7 and 5 were more involved than the rest.

CONCLUSIONMultiplex FISH in combination with conventional cytogenetics may characterize the complex chromosomal abnormalities more precisely. Introduction of this technique to the study of AML with complex chromosomal abnormalities is warranted.

This study was aimed to establish the technique of multiplex fluorescence in situ hybridization (M-FISH) and to explore its usefulness in detection of complex chromosomal aberrations (CCAs) in acute lymphoblastic leukemia (ALL). Five ALL patients with CCAs were analyzed by combining the techniques of conventional cytogenetics (CC) and M-FISH. The results demonstrated that M-FISH confirmed the aberrations previously detected by CC, such as t (9;22), t (1;19) and t (y;1), and revealed new abnormalities as der (1) (1::3::7), der (6) t (6;9) (q?;p13), der (1) t (1;11), der (12) t (1;12), der (3) t (3;5), der (2) t (2;16), der (9) (9::18::7) and der (7) (9::18::7), and also corrected the wrong results in CC. Among these abnormalities, der (9) (9::18::7) and der (7) (9::18::7) were reported for the first time. In conclusion, M-FISH has proved to be useful in characterization of the CCAs in ALL, and it is an essential method to refine the karyotype analysis.

OBJECTIVETo explore the molecular cytogenetic characteristics in patients with chronic lymphocytic leukemia (CLL).

METHODSInterphase fluorescence in situ hybridization (FISH) was used to detect trisomy 12, deletion of 13q14 and 17p13 in 60 patients with CLL.

RESULTSOut of the 60 patients, 41 (68.3%) had at least one kind of molecular cytogenetic aberrations. Two (3.3%) had two kinds of abnormalities. Trisomy 12 was found in 12 (20.0%) cases, 13q14 deletion in 24 (40.0%) cases and 17p13 deletion in 5 (11.7%) cases. The number of trisomy 12 cells ranged from 4.0% to 34.0%, 13q14 deletion ranged from 22.0% to 93.0% and 17p13 deletion ranged from 6.0% to 68.0%. There was no significant difference among each Binet stages.

CONCLUSIONFISH is a more rapid, accurate and sensitive technique in analysis of chromosome aberrations in CLL. FISH may provide accurate information of molecular cytogenetics for CLL.

OBJECTIVETo explore significance of high-risk human papillomavirus (HR-HPV) testing in atypical squamous cells, cannot exclude high grade squamous intraepithelial lesion (ASC-H).

METHODSPresence of HR-HPV DNA was examined in 45 patients with ASC-H using hybrid capture II (HC-II) test. Colposcopic examination and biopsy were taken all results were evaluated.

RESULTSOverall, 33 of 45 (73.3%) ASC-H cases were biopsy proven cervical intraepithelial lesion (CIN). 36 of 45 ASC-H cases were HPV-DNA positive, including 19 cases of HSIL and over lesion; whereas no HSIL or over was found in 9 HR-HPV negative cases. Sensitivity and negativity predictive value of HR-HPV in ASC-H with HSIL and over lesion were both 100%.

CONCLUSIONSASC-H strongly predicts the presence of HSIL, HR-HPV may serve as a predict select whether a patient with ASC-H should take colposcopic examination immediately, patients with positive HR-HPV should undergo immediate colposcopic examination, while negative HR-HPV is an excellent predictor of the absence of HSIL.
