Patients with HER-2-positive advanced breast cancer were associated with poor prognosis. Meanwhile, HER-2-targeted ther-apy has dramatically improved survival and prognosis among breast cancer patients. Over the years, multiple HER-2-targeting drugs stepped into clinical practice, and the targeted agents are now considered as the standard of care in the first-line setting and beyond. This review basically summarizes the importance of HER-2-targeted therapy, the significance of the clinical trial results, and the clinical practice guidelines for the management of patients with HER-2-positive advanced breast cancer.

Objective: To investigate the antidepressant effect and mechanism of the extract of mulberry leaf(EML). Methods: Male BALB/c mice were randomly assigned to receive EML(100, 200 and 400 mg/kg)or vehicle for 7 days or single administration by intragastric(ig)route. The effect of EML on spontaneous activity in mice was evaluated using the open field test. The anti-depressant activity of EML was evaluated using the tail suspension test and forced swimming test. After single ig administration of EML (100, 200 and 400 mg/kg), the effects of EML on the function central monoaminergic nervous system were evaluated using the 5-hydroxy-L-tryptophan(5-HTP)induced head-twitch test, yohimbine toxicity potentiation test and reserpine test in mice. Results: In the behavioral despair model, the continuous administration of EML(100 mg/kg)for 7 days significantly reduced the immobility time in the tail suspension test and forced swimming test. Compared with the vehicle group, the inhibitory rates of immobility time were 35.5% and 41%(P<0.05, P<0.01)in the tail suspension test and forced swimming test, respectively. The single treatment with EML(400 mg/kg)also significantly reduced the immobility time in the tail suspension and forced swimming test, and the inhibitory rates of immobility time were 29.1% and 35.3%, respectively(P<0.05). The results of spontaneous activity test showed that EML had no excitatory or inhibitory effect on the central nervous system in mice. In the 5-HTP induced head-twitch test in mice, the single treatment with EML(100 mg/kg)significantly increased the number of head-twitches in mice. In the yohimbine toxicity potentiation test, the single treatment with EML(100, 200 and 400 mg/kg)had no significant effect on the mortality rate in yohimbin-treated mice. In the reserpine test, compared with the model group, the single treatment with EML(400 mg/kg)antagonized reserpine induced ptosis (P<0.05)and had no significant effect on the decrease in rectal temperature and akinesia. Conclusion: EML showed antidepressant effect, and the action mechanism was likely related to the enhancement of the function of serotonergic nervous system.

Objective: A capillary electrophoresis for the determination of berberine hydrochloride and palmatine hydrochloride in Ruyijinhuang Powder(Rhizoma Curcumae Longae, Radix et Rhizome Rhei, Cortex Phellodendri, Rhizoma Atractylodis, etc.) was established. Methods: The berberine hydrochloride and palmatine hydrochloride were determined using benzoic acid as an internal standard its detection wavelength was at 230nm. The optimized condition was achieved with a fused\|silica capillary 100?m?56.5cm, 10mmol?L -1 phosphate buffer(pH=4.80) containing 30% acetonitrile, a constant voltage of 20kv and temperature at 30℃. Results: Calibration curve was constructed in the range of 5?g?mL -1 ～100?g?mL -1 for berberine hydrochloride and palmatine hydrochloride, respectively. The regression equations were Y=0.02964X -0.00771 ( r =0.9998) and Y =0.01092 X -0.02939 ( r =0.9997) for berberine hydrochloride and palmatine hydrochloride, respectively. The average recovery was 98.7% and 102.1%( n =5), respectively. Conclusion: This method is sample, quick and sensitive.

Objective To observe the efficacy of combination of pranoprofen and artificial tears in treatment of dry eye syndrome after recovery from acute conjunctivitis. Methods This study involved 206 eyes of 157 consecutive patients who had recovered from acute conjunctivitis after routine treatment between July 2008 and September 2010. All cases were randomly divided into artificial tears group (79cases,104eyes) : artificial tears eye drops alone and combination group(78cases,102eyes) : pranoprofen combined with application of artificial tears eye drops. All patients'symptoms, signs such as tear film break 2 up time (BUT ) ,Schirmer I test (SIT) , corneal fluoresce staining (FL) score at 3,7,14days after treatment Were observed. Results All patients finished the trial at the end of the follow-up duration. There were significant differences in symptoms, BUT and corneal fluoresce staining between the two groups after treatment,combination group was superior to artificial tears group in BUT and FL. Conclusion Pranoprofen combined with artificial tears eye drops is superior to artificial tears eye drops alone

AIM: Human herpesvirus 6B(HHV-6B) is the etiologic agent of exanthem subitum and is associated with febrile illnesses in children, neurological manifestations during primary infection, and clinical complications in organ transplant patients. The ORF U83 of HHV-6B has been identidied encoding a functional chemokine and U83 protein was detected out in brain tissues of some patients with multiple cirrhosis. The aim of this study was to establish HHV-6B U83 transgenic mouse lines, which would provide a pathological animal model for the research of the relationship between HHV-6B U83 gene and multiple cirrhosis. METHODS: Transgenic animal technique was applied in the present study. RESULTS: We successfully established 3 lines of transgenic mice with HHV-6B U83 gene integrated to their chromosomes, through constructing the DNA fragment which consisted of GFAP promotor, HHV-6B U83 and mouse protamine 1 sequence and injecting to the mouse eggs. CONCLUSION: This establishment of HHV-6B U83 transgenic mouse lines would benefit the observation and analysis of association of HHV-6B infection with neurological system diseases.

The review is focused on the development and recent research of the first tissue-specific angiogenic molecule,endocrine gland-derived vascular endothelial growth factor(EG-VEGF).It has been found that EG-VEGF only targeted on steroidgenic endocrine organs or cells through G-protein coupled receptor,the phosphorylation of G-protein coupled receptor could activate mitogen-activated protein kinase p44/42 and phosphatidylinositol-3 kinase(PI3K) pathways signal transdution.There are many reports that believes MAPK and PI3K is involved in the regulation of proliferation,migration,survival of endothelial cells and tumor angiogenesis,so EG-VEGF may serve as a potential target for antiangiogenic therapy of cancer in the future.

OBJECTIVE Approach the cause of esophageal perforation and the analysis of diagnosis, therapy and its outcome in this disease. METHODS We retrospectively review 11 patients of esophageal perforation between1997 and 2004 in our department. There were 9 cases were taken out foreign bodies from their esophageal, another 2 cases haven't been found any foreignbodies and 1 of 2 was caused by iatrogenic reasons. Perforation occurred in the cervical esophagus was 4, and in the thoracic esophagus was 7. Their symptoms were dysphagia or pain, retrosternal-pain, dyspnea, subcutaneous emphysema, fever, hematemesis or melena. RESULTS 7/11 cases visited the clinic during 24 hours after foreign-body occured, 4/11 cases visited after 24 hours and the last visited clinic on 27th day late. Dysphagia was the most common presenting symptom specially with pain in eating, noted in 9 cases (81.8 %); retrosternal-pain and fever were noted in 8 cases (72.7 %), subcutaneous emphysema in 5 (45.5 %), dyspnea in 2 (18.2 %), hematemesis and melena.in 1 (9.1 %). 5 cases were died and the common mortality was 45.45 % (5/11). The mortality in primary repair with surgery treatment was 66.7 % (2/3); the mortality in conservative management was 37.5 % (3/8). The mortality of the perforation in cervical esophagus was 25 % (1/4), in thoracic esophagus was 57.14 % (4/7). The mortality of the visit time in 24 hours was 28.57 % (2/7),and out of 24 hour was 75% (3/4). CONCLUSION Sophageal perforation is usually caused by foreign body or iatrogenic in ENT-Head&Neck surgery. The esophageal perforation will been cured that decided in early visiting, taking away of foreign-boby, the right choice of antibiotic, nutritional support, primary healthy statement of esophagus. We regard that should perform non-operational conservative therapy in the patients who resulted in esophageal perforation except abscess or remain causing by foreign body. And the high risks in mortality of the repairing in surgery should been noticed.
