OBJECTIVETo explore the clinical effect and therapeutic mechanism of Kangxian Baogan Decoction (KXBGD) on liver fibrosis caused by chronic hepatitis B.

METHODSEight-one patients with chronic hepatitis B were divided into two groups randomly. The 54 patients in the treated group were treated by KXBGD and the 27 patients in the control group were treated by conventional liver protecting treatment. Serum levels of hyaluronic acid (HA), procollagen type III (PC III), collagen type IV (C-IV), laminin (LN), transforming growth factor beta 1 (TGF beta 1) and tumor necrosis factor-alpha (TNF-alpha) were measured before and after treatment, meanwhile, liver function and pathological changes of liver tissues were observed.

RESULTSThe total effective rate in the treated group was significantly higher than that in the control group. Serum levels of HA, PC III, C-IV, LN, TGF beta 1 and TNF-alpha in the treated group obviously reduced after treatment, and the liver function got better with significant difference as compared with those in the control group (P < 0.05 or P < 0.01). Pathological examination of liver biopsy showed that the fibrous tissue in the liver reduced.

CONCLUSIONKXBGD has a definite effect of anti-liver fibrosis.

OBJECTIVETo investigate the effect of Tongxinluo capsule (TXLC) on the patients with unstable angina pectoris (UAP).

METHODSPatients of UAP were divided into two groups, the treated group (n = 60) was treated with TXLC and the Danshen group (n = 30) was treated with composite Danshen tablet. The plasma endothelin (ET) and calcitonin gene related peptide (CGRP) were measured before and after treatment. Data were compared between the two groups and also compared with those measured in 20 healthy subjects for control.

RESULTSET level was higher and CGRP level lower significantly in UAP patients than that in healthy subjects significantly (P < 0.05). After TXLC treatment, ET significantly lowered (P < 0.01) and CGRP increased (P < 0.05). But in the Danshen group after treatment, the former decreased (P < 0.05), while the latter remained unchanged (P > 0.05). The effect of TXLC was better than that of composite Danshen tablet.

CONCLUSIONTXLC is an effective drug for UAP treatment, which could efficiently regulate the ET and CGRP metabolism and ameliorate the degree of myocardial ischemia damage.

UNLABELLEDTo observe the clinical effect of drug cupping therapy (DCT, cupping therapy with pingchuan ointment made by the authors themselves in the cups) on chronic asthmatic bronchitis (CAB) during the protracted period, and explore its effect on immune function.

METHODSSeventy-seven patients were randomly divided into two groups:the treated group (n=40) treated by orally taken Liuwei Dihuang Pill (LDP) and DCT and the control group (n=37) with LDP and common cupping therapy without drug in cups. The changes of T-lymphocyte subset, levels of interferon-gamma (IFN-gamma), interleukin (IL), immunoglobulin (Ig), complement 3 and 4 (C3 and C4) were detected before and after treatment.

RESULTSThe total effective rate was higher in the treated group than that in the control group (90.0% vs. 59.5%, P < 0.01). The levels of CD4+, CD4+ /CD8+, IL-2, IFN-gamma, C3, C4, IgA, IgG and IgM increased, while the levels of IgE, IL-4, IL-10 and CD8+ decreased after treatment in both groups (P < 0.05 or P < 0.01), the improvements were better in the treated group than that in the control group (P < 0.05).

CONCLUSIONDCT shows better curative effects than that of common cupping therapy without drug, it could improve the cellular and humoral immunity in CAB patients.

OBJECTIVETo explore the mechanism of Wenfei Huayin Recipe (WHR) in treating chronic obstructive pulmonary diseases (COPD).

METHODSThe COPD model was induced by modified fumigating method and intra-tracheal instillation of lipopolysaccharide. Then reformed COPD model of cold-phlegm retention in Fei syndrome type. All the model rats were randomly divided into two groups, the model group and the treated group, treated respectively with WHR and saline for 14 successive days. Besides, a blank group without any intervention was set up for control. The general condition, weight growth rate, pathological changes of lung tissue under light microscope, ultrastructure under electron microscope, arterial blood gas analysis and levels of interleukin 4 (IL-4), interleukin 8 (IL-8), tumor necrosis factor alpha (TNF-alpha) and interferon gamma (IFN-gamma) in lung homogenate by radio-immunity assay were observed.

RESULTSIn the treated group, as compared with the control group, the symptoms of aversion to cold, swarming, wheezing, the degree of epithelial cell degeneration and necrosis, the inflammatory cell infiltration and the volume of cilia lodging, sloughing, and bullae of lung were lessened and weight growth rate was higher (P<0.01). Moreover, the treated group was superior to the control group in decreasing levels of PaCO2, IL-4, IL-8, TNF-alpha and increasing PaO2, IFN-gamma and IFN-gamma/IL-4 ratio (P<0.01 or P<0.05).

CONCLUSIONWHR can correct the Th1/Th2 imbalance and inhibit the inflammatory reaction, displaying an important role in improving the airway function and structure in COPD rats.

OBJECTIVETo study the effects of arsenic trioxide on apoptosis of peripheral T-lymphocytes from asthmatic patients and normal subjects in vitro.

METHODSThe T-lymphocytes were isolated from the blood of 21 asthmatic patients and 20 healthy controls and treated with arsenic trioxide and dexamethasone. Cell apoptosis was observed by fluorescence microscope and measured with flow cytometry and Cytochrome C ELISA kit.

RESULTSThe T-lymphocytes from the asthmatic patients, when compared to those from of the healthy control, exhibited decelerated spontaneous apoptosis after a 24-hour incubation in vitro. Dexamethasone treatment significantly increased the percentage of apoptotic T-lymphocytes from both asthmatic patients and normal subjects in comparable magnitude. Arsenic trioxide treatment, in contrast, significantly increased the percentage of apoptotic T-lymphocytes from asthmatic patients, but slightly affected the cells from the control group.

CONCLUSIONSSpontaneous apoptosis of T-lymphocytes can be decelerated in asthmatic patients, whose T-lymphocytes are more sensitive to arsenic trioxide-induced apoptosis than those of normal subjects, but the T-lymphocytes from normal subjects and asthmatic patients are equally sensitive to dexamethasone.

Objective: The current study was designed to evaluate the clinical application of radioimmunoimaging(RII) for lymph node metastasis in esophageal carcinoma. Methods:1)131I was used to label McAb G9(specific to cellular membrane antigen of human esophageal carcinoma) and form labeling compound 131I-G9. Administration of 131I-G9 in esophagus submucosally with a specific injector for the purpose of submucosal injection via endoscopies in preoperative patients with squamous cell carcinoma of thoracic esophagus followed by RII. 2)The samples of dissected lymph node were used for detection of radioactivity. Results: 1)The pictures at 48 h showed that small radioactivity concentrated dots appeared dispersedly in mediastinum and upper abdomen around esophagus and cardiac gastric. The lymph nodes were considered metastatic in above regions. 2)The pathological results of the lymph nodes dissected compared to the RII result. The metastatic lymph nodes were found in the regions of dispersedly concentrated radioactivity, while no metastatic lymph nodes could be found in the radioactivity free regions. 3)After counting for radioactivity, lymph node metastases showed higher antibody uptake than the non-metastases lymph nodes. The difference was statistically significant. Conclusion: 131I-G9 may be used to locate metastatic lymph nodes in patients with esophageal carcinoma.

OBJECTIVETo compare the effect of Sodium Morrhuate on ECV-304 between its lipo- and normal preparation.

METHODSThe ECV-304 cell line was supplemented with Sodium Morrhuate and lipo-Sodium Morrhuate in order, and the result on morphology (microscope, Giemsa Staining and electron microscope), cell activity (MTT), and flow cytometer between the two preparation were compared.

RESULTSIn normal preparation group, cell's edema occurred. Chromatin was like catkins. Tumefaction and degeneration of mitochondrion and endoplasmic reticulum appeared. In lipo-Sodium Morrhuate group, the membrane was creased and processus appeared. Chromatin aggregates to the membrane of nucleus was like crescent, and then broken. The apoptotic body was formed. MTT changes showed that the curve of the normal preparation group was steep and the change time was short relatively, which cues the vital cells decreased sharply. The curve of lipo-Sodium Morrhuate group was gentle and the change time was long relatively, which cues the vital cells decreased slowly. The flow cytometer showed that typical apoptosis peak appeared.

CONCLUSIONThe normal preparation group shows an acute toxic effect on ECV-304 cell line, which result in a necrosis course, while lipo-Sodium Morrhuate shows a gradual releasing process, which may indicate a apoptosis course.

Objective To evaluate the clinical significance of bone scintigraphy in the preoperative diagnosis of sacral tumor. Methods Preoperative 99Tcm-methylene diphosphonate (MDP) whole body bone scintigraphy was performed in total of 103 patients with sacral tumor for whole body survey and radionuclide uptake in the sacral tumor. Of these 103 patients,39 had SPECT. According to the osteoblastic reaction in bone SPECT studies,patterns of tumor with a "hot" lesion was defined as type Ⅰ,a "cold" lesion accompanied with partial uptake was defined as type Ⅱ,a purely "cold" lesion was defined as type Ⅲ,and a "cold" lesion with marginal uptake which produced "doughnut sign" was defined as type Ⅳ. Imaging interpretation was correlated with the final pathologic diagnosis. Results Of the 103 patients,18 ( 17.5% ) had polyostotic involvement. About 46.6% (48/103 ) in planar and 84.6% ( 33/39 ) in SPECT showed decreased uptake at sacrum. Of the bone metastatic patients (n =21 ) ,12 (51.7%) had sole metastasis to sacrum. Tumor with type Ⅰ (6/6) or type Ⅱ (16/19) uptake was likely to be a malignancy,whereas type Ⅲ uptake tended to occur in the benign disease in those patients without polyostotic involvement( 5/7 ),and type Ⅳ was all appeared in giant cell tumors( n = 5 ). Conclusions Preoperative bone scintigraphy is useful in examination of polyostotic involvement for the patients with sacral tumor,but it is limited for diagnosing isolated sacral metastatic disease. Tumor uptake on bone scintigraphy can be helpful in differential diagnosis of sacral tumor.

OBJECTIVESTo evaluate the efficacy and safety of imatinib mesylate (imatinib) for myeloproliferative neoplasm (MPN) patients with eosinophilia.

METHODSEight MPN patients with eosinophilia and positive FIP1L1-PDGFR alpha gene and one CEL, NOS were treated with 100 mg or 400 mg/d imatinib orally.

RESULTSHematological remission (HR) rate was 100%, including complete HR (CHR) rate 87.5%, and partial remission (PR) rate 12.5% with a median follow-up of 16 (6.0 -26.0 ) months. Complete molecular remission (cMR) rate was 85.7%. The median time of FIP1L1-PDGFR alpha fusion gene becoming negative was 4 (1.5 - 8) months. Three patients withdrew imatinib after getting cMR. After a median follow-up of 12 months, all the 3 patients remained in CHR. The main adverse effect of imatinib was mild myelosuppression occurring in 37.5% of patients in a median time of 6 (4 - 9) days after treatment.

CONCLUSIONImatinib in treatment of MPN with eosinophilia and positive FIP1L1-PDGFR alpha gene patients can induce high hematologic and molecular remission. The adverse effects of imatinib are mild and tolerable.

BACKGROUNDThe pathogenesis of acute pancreatitis is complex and largely unclear. The aim of this study was to explore the relationship between modes of cell death in pancreatic acinar cells, the release of cell contents and the inflammatory response of macrophages.

METHODSOur experiment included four groups: group A (the control group), group B (AR42J cells overstimulated by caerulein), group C (AR42J cells treated with lipopolysaccharide and caerulein), and group D (AR42J cells treated with octreotide and caerulein). Apoptosis and oncosis, and the release of amylase and lactate dehydrogenase (LDH) from AR42J cells were detected. Rat macrophages were stimulated by 1 ml supernatant of culture medium of AR42J cells. Finally, NF-kappaB activation and TNF-alpha and IL-1beta secretion by macrophages were detected.

RESULTSOncotic cells in group C increased while apoptotic cells decreased (P < 0.05); cells in group D had the inverse reaction. The release of amylase and LDH changed directly with the occurrence of oncosis. The transcription factor NF-kappaB was activated and secretion of TNF-alpha and IL-1beta were significantly higher in group C than in group B (P < 0.05); in group D, these actions were significantly lower than in group B (P < 0.05). This trend was in line with changes in amylase and LDH production.

CONCLUSIONThere is a close relationship between modes of pancreatic acinar cell death, the release of cell contents and the inflammatory reaction of macrophages.
