To analyze and compare the protective effects of active components in different ethyl acetate extracts (EAEEPs) from Eclipta prostrate, in order to study the comparison of materials bases protecting normal human bronchial epithelial (NHBE) cells. The MTT assay was taken to compare the protective effect of different EAEEPs on cigarette smoke extracts (CSE) -induced NHBE cells. The ultra-performance liquid chromatography (UPLC) was applied to analyze the content of phenolic acid, coumaric grass ether and flavonoid in EAEEPs. According to the results, all of the eight EAEEPs (0-200 mg x L(-1)) showed certain protective effect on NHBE cells, with statistical difference. Specifically, the total mass of EAEEP VII (89.15 mg x L(-1)) and EAEEP VIII (57.44 mg x L(-1)), which showed the strongest activity, was not the highest, while EAEEP III (132.25 mg x L(-1)) displayed the highest total mass. In the combination with the "component structure" theory, the analysis showed a significant difference in the mass structure among phenolic acid, coumaric grass ether and flavonoid in EAEEP VIII and EAEEP VIII, which were 1.0: 1. 0: 0.5 and 1.0: 1.9: 0.8, respectively. The results suggested a specific optimal "component structure" relationship may exist in EAEEP, which could provide reference for the material base study and quality control.

OBJECTIVETo analyze the clinical and laboratory features of anti-soluble liver antigen/liver-pancreas (SLA/LP) autoantibody positive patients with abnormal liver functions.

METHODSFrom July 1999 to August 2004, 4928 serum samples from patients with abnormal liver functions (ALT >40 U/L) were collected. A series of autoantibody examinations were carried out. Clinical manifestations and laboratory findings of 8 patients with anti-SLA/LP autoantibody positive were reviewed.

RESULTSAmong the 5500 serum samples, 8 cases (6 females and 2 males) with positive anti-SLA/LP autoantibodies were found with complete clinical information. The age of the patients was (27-76) years old. The case histories were from 2 years to 10 years. Of the 8 patients, 6 cases had liver cirrhosis and HBsAg-negative and anti-HCV-negative, active, 1 case had liver cirrhosis with HBsAg-positive, but HBVDNA negative; 1 case had liver cirrhosis and anti-HCV positive, but HCV RNA negative. The 8 cases were all ANA positive with titers of 31:320. Four cases were AMA positive and 2 among these 4 cases were M2 positive. The most frequent symptoms were fatigue, anorexia, nausea, jaundice, abdominal distention and edema of lower limbs. All patients had high hypergammaglobulinemia.

CONCLUSIONAnti-SLA/LP autoantibody was at a low detection rate in the study with females in preponderance, Clinical and laboratory characteristics of the 8 cases were consistent with those of the autoimmune hepatitis (AIH). Testing for anti-SLA autoantibodies helps in the diagnosis of AIH in many patients who may otherwise be misdiagnosed.

OBJECTIVETo compare the differences in the efficacy on distant version of naked eye in the patients of juvenile myopia between rotating manipulation and lifting-thrusting manipulation of acupuncture.

METHODSOne hundred and twenty cases (240 eyes) were randomized into a rotating manipulation group and a lifting-thrusting manipulation group, 60 cases (120 eyes) in each group. Additionally, a corrective lenses group, 60 cases (120 eyes), was set up as the control. In both manipulation groups, Cuanzhu (BL 2),Yuyao (EX-HN 4), Sizhukong (TE 23), Taiyang (EX-HN 5), Fengchi (GB 20), Zusanli (ST 36), Guangming (GB 37) and Sanyinjiao (SP 6) were punctured, but stimulated with rotating manipulation and lifting-thrusting manipulation respectively three times per week, 10 times as a treatment session and totally one session was required. In the corrective lenses group, the glasses were applied at daytime. The clinical efficacy and the changes in distant vision of naked eye before and after treatment were compared among the three groups.

RESULTSThe total effective rate was 87.5% (105/120) in the rotating manipulation group, which was better than 69.2% (83/120) in the lifting-thrusting manipulation group (P < 0.05). The distant vision of naked eye was improved apparently in the rotating manipulation group and the lifting-thrusting manipulation group after treatment (both P < 0.05). But it was not improved in the corrective lenses group (P > 0.05). The distant vision of naked eye was improved more apparently after treatment in the rotating manipulation group as compared with that in the lifting-thrusting manipulation group (0.75 +/- 0.23 vs 0.68 +/- 0.24, P < 0.05). For 96 cases (192 eyes) with acupuncture treatment, in 3-month follow-up, 87.0% (167/192) of the cases maintained the stable vision as the original level and 13.0% (25/192) of them were reduced in the vision In the acupuncture groups, it was found that the improvement of distant vision of naked eye was more obvious after treatment with younger age, better basic vision and shorter duration of sickness (all P < 0.05).

CONCLUSIONAcupuncture achieves the positive and sustainable clinical effect on juvenile myopia, and the results of rotating manipulation are superior to that of lifting-thrusting manipulation. Age, basic vision and duration of sickness impact the clinical efficacy.

AIM To study the effects of Danggui Buxue Decoction total glycosides combined with Hirudo in the treatment of pulmonary fibrosis in rats and its mechanism.METHODS One hundred and twenty male SD rats were selected,eighteen of which were taken as normal group (normal saline),the remaining 102 rats were used to establish model for pulmonary fibrosis.Seventy-two modeled rats were randomly divided into model group (normal saline),Danggui Buxue Decoction total glycosides group (13 mg/kg),Hirudo group (Hirudo powder,4 g/kg) and combination group (Danggui Buxue Decoction total glycosides,13 mg/kg;Hirudo powder,4 g/kg),eighteen rats in each group with intragastric administration.RESULTS On the 7th,14th and 28th days after modeling,alveolar inflammatory score,pulmonary fibrosis degree score,TGF-β1 and PAI-1 expression levels in lung tissue,IL-4 and IL-17 expression levels in alveolar lavage fluid,hydroxyproline (HYP) content in lung tissue in the model group were significantly higher than those in the normal group (P ＜ 0.05).Alveolar inflammatory score,pulmonary fibrosis degree score,TGF-β1,PAI-1,IL-4,IL-17 expression levels and HYP content in the Danggui Buxue Decoction total glycosides group,Hirudo group and combination group were significantly lower than those in the model group (P ＜ 0.05).In the combination group,alveolar inflammatory score,pulmonary fibrosis degree score,TGF-β1,PAI-1,IL-4,IL-17 expression levels and HYP content were significantly lower than those in the Danggui Buxue Decoction total glycosides group and Hirudo group (P ＜ 0.05).CONCLUSION Danggui Buxue Decoction total glycosides combined with Hirudo have good therapeutic effects on pulmonary fibrosis in rats mainly by reducing TGF-β1,PAI-1 expression levels and HYP coment in lung tissue.

AIMTo observe the effect of angiotensin-converting enzyme inhibitors (ACEI) and aldosterone receptor blockers on cardiac function to explore the mechanism of cardiac function descending and myocardial injury in calcium-overload rats.

METHODSCalcium-overload in rat was induced by administration of Vitamin D3 plus nicotine. To Estimate the extent of calcium-overload by calcium content. Angiotension II and aldosterone levels in the myocardia were measured by radioimmunoassay. Cardiac function (+/- LVdp/dt, LVESP and LVEDP) were measured by Powerlab. The malondialdehyde (MDA) content, activities of lactate dehydrogenase (LDH) and creatine kinase (CPK) were measured by biochemistry.

RESULTSCalcium content increased by 3.2-, 5.8 -fold in myocardial and artery, compared with controls. VDN-treated survivors showed lower + LVdp/dt(max) and -LVdp/dt(max) values, by 27% and 34%, respectively (both P < 0.01). Higher LVESP, and LVEDP by 42 % and 32% (P < 0.01); heart rate and mean arterial pressure were not significantly altered (P > 0.05). The lipid peroxidation products MDA and conjugated diene in myocardia were increased 22% (P < 0.01), 68% (P < 0.05) (P < 0.05), respectively. The plasma activity of CPK and LDH was greatly increased by 4.5-and 3.1-fold (P < 0.01), respectively. ACEI and spironolactone obviously relieved degree of calcium-overload and improved cardiac function and myocardial injury(P < 0.01). Calcium content in myocardia and artery was lower 44%, 39% and 57%, 34%. Lower MDA by 20%, 30%, lower conjugated diene by 44%, 35% than calcium-overload group. The plasma activity of CPK and LDH were obviously decreased 28%, 34% and 20%, 27%, compared with calcium-overload group.

CONCLUSIONCalcium-overload could lead to cardiac function descending and myocardial injury in calcium-overload rats by VDN. ACEI and spironolactone could reduce calcium-overload in myocardial and ameliorate cardiac function and decrease myocardial injury.

OBJECTIVETo study CXCR3 and CCR5 chemokine receptor expression in spleens of patients with primary immune thrombocytopenia (ITP) and its clinical significance.

METHODSThe splenectomy specimens from 10 ITP patients (ITP group) and 8 patients with traumatic splenic rupture (normal control group) were studied. Immunohistochemistry (IHC) was used to study the positive rate of CXCR3 and CCR5. Western blot was performed to detect CXCR3 and CCR5 protein expression, while real-time polymerase chain reaction (RT-PCR) was conducted to analyze their mRNA expression.

RESULTSThe positive rate of CXCR3 and CCR5 were both higher in ITP group (90% and 100%, respectively) than those in control group (75% and 87.5%, respectively)(P < 0.05). The differences were statistically significant (P < 0.05). Protein and mRNA level of CXCR3 in ITP group were 3.0 and 3.5 times as high as those in control group, respectively. Those of CCR5 in ITP group were 1.2 and 1.7 times as high as those in control group, respectively.

CONCLUSIONHigh expression of CXCR3 and CCR5 may play a part in the splenic immune disorders in patients with ITP.

OBJECTIVETo study the clinical significance of tidal breathing lung function test in 1-4 years old children with wheezing diseases.

METHODSA total of 141 1-4 years old children with wheezing diseases were enrolled as the observed groups (41 cases of asthma, 54 cases of asthmatic bronchitis, and 46 cases of bronchopneumonia). Thirty children without respiratory diseases were enrolled as the control group. All the recruits underwent tidal breathing lung function test. The observed groups underwent bronchial dilation test, and tidal breathing flow volume (TBFV) parameters were evaluated before and after bronchial dilation test.

RESULTSThe observed groups showed obstructive ventilatory disorder (65%) according to the TBFV loop, and their ratio of time to peak tidal expiratory flow (TPTEF) to total expiratory time (TE) and ratio of volume to peak expiratory flow (VPEF) to total expiratory volume (VE) were significantly lower than in the control group (P<0.05). The asthma subgroup had significantly improved TPTEF/TE and VPEF/VE after bronchial dilation test (P<0.05). Taking an improvement rate of ≥ 15% either for TPTEF/TE or for VPEF/VE as an indicator of positive bronchial dilation test, the bronchial dilation test had a sensitivity of 47% and a specificity of 84% in diagnosing asthma in 1-4 years old children. The positive rate was 28% among the children in the asthma subgroup with an TPTEF/TE ratio of ≥ 23% before bronchial dilation test, versus 65% in those with an TPTEF/TE ratio of <23%.

CONCLUSIONSObstructive ventilatory disorder is the main impairment of tidal breathing lung function in 1-4 years old children with wheezing diseases. Tidal breathing bronchial dilation test can reflect a reversal of airway obstruction to a certain extent. The sensitivity of bronchial dilation test for the diagnosis of asthma is not satisfactory in 1-4 years old children with wheezing diseases, but this test has a relatively high diagnostic value in children with severe airway obstruction.

OBJECTIVETo explore the plausibility of laryngeal preservation in salvage surgery of recurrent laryngeal carcinoma.

METHODSComprehensive clinical and radiological assessments on a specific group of patients with recurrent laryngeal cancer and their relapsed tumors were carried out to determine the methods and indications of salvage surgery for preservation of laryngeal functions. Salvage surgery with preservation of larynx was performed in a selective of 36 laryngeal cancer patients with relapsed tumors in their larynges after radiotherapy or partial laryngectomies. All patients were regularly followed up after discharge from the hospital. Postoperative survival was calculated by Kaplan-Meier's method.

RESULTSAmong various laryngeal preservation regimens given, a second transoral laser surgery was carried out in 4 cases, horizontal hemilaryngectomy in 4 cases, vertical hemilaryngectomy in 13 cases and Majer-Piquet's operation in 15 cases, respectively. Simultaneous neck dissection was conducted in 18 cases. Postoperative complications were encountered in 6 cases, most common of which were local infection and laryngeal fistula with no hospital mortality and other major morbidities. Five cases with immediate postoperative complications were cured with proper management. The remained one case undergone vertical partial laryngectomy for recurrence after tumor resection via laryngeal fissure received postoperative radiation due to positive surgical margin, and complicated laryngeal atresia and obstruction with loss of his laryngeal functions. Local recurrence was observed in 5 cases and simultaneous locoregional recurrence was seen in 1 case, with the resulting local control rate of 83.3% (30/36). The 3-year postoperative survival rate was 80.6%. The cause of death was tumor recurrence in 3 cases, distant metastasis in 3 cases and non-tumor-associated disease (heart attack) in 1 case, respectively.

CONCLUSIONSSalvage surgery with laryngeal preservation can be carried out in the selected cases with early or locally-confined recurrent lesions within the larynx, on the condition that the recurrent tumors be assessed thoroughly and indications for associated surgical techniques be evaluated properly.
