The Her-2 proto-oncogene encodes a 185kDa transmenbrane glycoprotein p185 which has intrinsic tyrosine kinase activity. It is overexpressed in several malignant human tumors like breast cancer. A chimeric antibody by assembling a single-chain Fv antibody and a human IgG1 Fc fragment was constructed. This chimeric antibody reacts with tumor surface antigen p185c-erbB-2 specifically. In order to put the antibody into clinical application, two steps purification method was used to attain the antibody’s purity more than 95%. Both the lyophilized pharmaceutical formulations of the antibody were found. The formulations can keep the stability and activity of the antibody for at least one year. These results were the foundation of the chimeric antibody for cancer therapy.

OBJECTIVETo study the effect of Yiqi Wenyang Huoxue Lishui principle (YWHL, a therapeutic principle with Chinese medicine for reinforcing Qi warming Yang, activating blood circulation and promoting urination) on some neuroendocrine factors in patients with congestive heart failure (CHF).
METHODSForty-nine patients of CHF with heart function of grade III-IV were randomly divided into 2 groups. The 29 cases in the treated group were treated with YWHL and the 20 cases in the control group treated with captopril. Changes of angiotensin II (AT II), atrial natriuretic peptide (ANP), endothelin (ET), nitric oxide (NO) and alpha-granule membrance protein -140 (GMP-140) were observed.
RESULTSAfter treatment, plasma level of AT II, ANP, ET, and NO lowered in both groups with insignificant difference, but the GMP-140 reduced more significantly in the treated group (P < 0.05).
CONCLUSIONYWHL showed a regulatory effect of neuroendicrine system partially similar to that of angiotensin-converting enzyme inhibitor, it possibly can improve the ventricular remodeling and would be beneficial to prevent the thrombus formation and improve heart failure by means of inhibiting platelet activity.

The proteins encoded by the Herpesviridae β-gene play a critical role in the replication stage of the virus. In this paper, phylogenetic analyses provided evidence that someβ-gene products, such as UL2 and UL23 from HSV1, have their homologous genes in its family, and also exist in prokaryotic organisms, indicating that these viruses appear to have been assembled over evolutionary time by numerous independent events of horizontal gene transfer.

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.

OBJECTIVETo investigate the clinicopathologic features and the prognostic factors of endometrial stromal sarcoma (ESS).
METHODS55 cases of endometrial stromal sarcoma were reviewed and categorized into 3 pathologic types based on the related literatures, i.e., low grade endometrial stromal sarcoma (LGESS), undifferentiated endometrial sarcoma with nuclear uniformity (UES-U) and undifferentiated endometrial sarcoma with nuclear pleomorphism (UES-P). Meanwhile, the pathologic features were reviewed, including fibroid, myoid, mucoid, and epithelioid differentiation and mitotic index. Clinical and follow-up data were collected.
RESULTSIn endometrial stromal sarcoma, two or three pathologic types co-existed in one case, including 12.8% (5/39) of LGESS, 5/9 of UES-U, and 5/7 of UES-P. Mitotic index varied in different regions of one tumor from rare to high. Multi-differentiation was also commonly seen in ESS. The numbers of cases in LGESS, UES-U and UES-P were 39, 9 and 7, with recurrence rate of 51.6% (16/31), 5/6 and 2/3, respectively. There was no death case in LGESS, and 2 cases were died in UES-U and UES-P, respectively. In the 2 death cases of UES-U, both had focus of UES-P. There was a significant difference in the recurrence rate between cases with different mitotic index (≥ 10/10 HPF and < 10/10 HPF, P = 0.009), especially in LGESS group. All death cases had high mitotic index (> 30/10 HPF).
CONCLUSIONSIt is a common phenomenon in ESS that two or three pathologic types may exist in one case, especially in UES-U and UES-P. And multi-differentiation is also commonly seen in ESS. So adequate pathologic sampling is important for pathologists to make a correct diagnosis of ESS in daily work. The recurrence rates are significantly higher in cases with high mitotic index, especially in LGESS. In addition, the presence of UES-P and high mitotic index may increase the risk of death in the patients.

Objective To construct PPAR?and PPAR?response element (PPRE)-controlled luciferase expression vectors,and to determine whether the traditional Chinese medicine emodin activates PPAR?and improves the glucose uptake by HepG2 hepatocytes.Methods (1) PPAR?and PPRE luciferase expression vectors were constructed and were applied to screen more than 20 ingredients of the traditional Chinese medicine. (2) HepG2 cells were incubated with emodin which can activate PPAR?and PPRE luciferase activity,and the PPAR?mRNA expression level was evaluated by RT-PCR/Southern blot.(3) PPAR?and glucose transporter 2 (Glut2) proteins were determined by Western blot analysis in HepG2 cells treated with emodin.(4) The glucose uptake rate was measured using 2-deoxy-[~3H]-D-glucose in HepG2 cells after treatment with emodin.Results (1) Emodin stimulated luciferase activity controlled by PPRE in dose-dependent manner at concentrations of 0.04 to 180?mol/L in COS-7 cells.The highest value was about 4 folds of control in the cells treated with 90?mol/L emodin (P
