Objective: To investigate the impulsivity of SHR (spontaneous hypertensive rat, the animal model of attention deficit/hyperactivity disorder), and compare it with the WKY (Wistar Kyoto Rats).Method:The experiment was carried on in the standard Campden instrument operant chambers, the animals were 22h deprived of water. A long Variable Interval Schedule was used and the stable documents of the last ten days were analyzed.Result:There was no significant difference of the reinforcement between SHR and WKY rats. The short inter-response times (IRTs) of SHR were much higher than that of WKY rats. There was no significant difference of short IRTs of the two groups among the three same segments of the experiment.Conclusion:The impulsivity of SHR is more obvious than WKY rats. It will be helpful for the biological research of ADHD.

Atomoxetine is a noradrenaline transmitter reuptake inhibitor which can selectively inhibit presynaptic noradrenaline transport protein,strengthen noradrenaline's resupination effect,and increases noradrenaline's activity released by synaptic cleft to improve the symptoms of the attention deficit hyperactivity disorder(ADHD)patients.ADHD patients often accompany with other psychological diseases like oppositional defiant disorder,anxiety disorder,which may hinder the diagnosis of ADHD.There is still no accepted effective medicine nowadays.Currently,research on the treatment of the ADHD is more and more popular.Good therapeutic effect of atomoxetine to treat ADHD has been found in resent studies.This article summarized the current management of using atomoxetine to treat ADHD.

Objective To improve the recognization of bilateral adrenal tumors from different tissues and to discuss the treatment.Methods One case of bilateral adrenal tumors from different tissues:pheochromocytoma in one side and adrenocortical adenoma in the other side was reported and the data of syptoms,physical features,auxillary examination,diagnosis and treatment were retrospectively reviewed.Results The patient was diagnosed as adrenocorticotropic hormone (ACTH) -independent Cushing's syndrome in other hospital and received laparoscopic adrenalectomy for right adrenal tumor.During the operation the blood pressure fluctuated seriously and was even more than 200 mm Hg.The pathological report showed the mass was pheochromocytoma.After the operation,the patient's clinical manifcstation was not changed.Half a year later the lab test showed blood ACTH was still less than 5 pg/ml,24 h urinary-free cortisol (UFC) was 571.32 μg,and 24 h urinary catecholamines (U CA) was:noradrenalin (NE) 22.80 μg,epinephrine (E) 2.55 μg,dopamine (DA) 92.92 μg.CT detected a mass in left adrenal gland.The patient received laparoscopic adrenalectomy for left adrenal tumor after being transferred to Peking Union Medical College Hospital.The tumor was proved as adrenocortical adenoma by postoperational pathology.One week after the operation,the 24 h UFC was 56.2 μg.Conclusions Bilateral adrenal tumors from different tissues are very rare in clinic.Adrenalectomy for tumors from both sides and remaining the normal adrenal glands are recommended.

Andrographis paniculata from different parts and origins were analyzed by UPLC-PDA fingerprint to provide refererice for related preparation technology. Using the peak of andrographolide as reference, 27 common peaks were identified, and digitized UPLC-PDA fingerprints for 23 batches of andrographis paniculata were established in this research. Principal component analysis (PCA) was carried out after feature extraction. The contents of andrographolide, neoandrographolide, deoxyandrographolide, dehydroandrographolide were determined by external standard method. The Plackett-Burman design combined with pareto chart was used to analyze the factors influencing the robustness of the method. It was found that the medicinal part has a more remarkable influence on the quality of andrographis paniculata than the origin. The contents of the 4 lactones the differ greatly in the different parts of andrographis paniculata, and the pH of the mobile phase is an important factor that influenced the robustness of the method.

OBJECTIVE To study the molecular mechanism of cisplatin(DDP)by which HeLa cell growth and proliferation are inhibited. METHODS Cultured HeLa cells were treated with DDP 0.02-75 μmol · L-1 for 24 or 48 h. CCK-8 assay was used to determine the cell proliferation. The wound scratch assay was used to detect the cell migration and invasion. Flow cytometry was used to detect the cell cycle arresting. q-PCR was used to test the expression of metastasis suppressor gene 1 (MTSS1)mRNA. Western blot was used to determine protein levels of MTSS1,phosphorylated-extra?cellular signal-regulated kinase(p-ERK) and phosphorylated-serine-threonine kinase(p-AKT). RESULTS Following the treatment with DDP for 24 or 48 h,the proliferation of HeLa cells was inhibited significantly (P<0.05),the value of the half inhibitory concentration (IC50) of cells was 4.14 and 11.82 μmol · L-1. Migration and invasion activity of HeLa cells were reduced according to the wound scratch assay(P<0.05). Flow cytometry results showed that the cell cycle was arrested at S phase. q-PCR results showed that MTSS1 mRNA expression changed with DDP in a concentration-dependent manner (r24 h=-0.965,P<0.01;r48 h=-0.953,P<0.01). Western blot showed that the protein levels of MTSS1,p-ERK and p-AKT expression declined significantly with the increase in DDP concentrations(p-ERK:r24 h=-0.875,P<0.01;r48 h=-0.966,P<0.01. p-AKT:r24 h=-0.831,P<0.01;r48 h=-0.863,P<0.01. MTSS1:r24 h=-0.969,P<0.01;r48 h=-0.988,P<0.01). CONCLUSION DDP treatment inhibits HeLa growth and proliferation by interfering with the MTSS1 expression and disturbing the activation of ERK and AKT signaling pathways.

Objective To detect the expression of metastasis sappressor 1(MTSS1) gene in cervical cancer tissue and to clarify its association with cervical cancer.Methods Totally 103 cases of cervical tissue were collected between Dec 2011 and Dec 2014 and classified according to biopsy and stage .Q-PCR and Western blotting were used to detect the expression of MTSS1 in normal cervical tissue and in different clinical stages of cervical cancer tissue .Results The expression of MTSS1 inⅡB-Ⅳstages of cervical cancer tissue was significantly higher than that of normal tissue or Ⅰ-ⅡA stages through q-PCR (P=0.000).Western blotting results showed that MTSS1 was positively expressed in normal cervical tissue at a rate of 23.3% or 53.3% in cervical cancer tissue.Moreover, the expression of MTSS1 was poorly correlated with age, tumor differentiation and lymphnode metastasis in cervical cancer tissue (P>0.05).The protein level of MTSS1 expressed in ⅡB-Ⅳ stages was significantly higher than that ofⅠ-ⅡA stages(P=0.005).Conclusion The expression of MTSS1 indicates the clinical stage of cervical cancer , suggesting that MTSS1 may play an important role in the development of cervical cancer .

Blood-brain barrier (BBB) is a kind of important barrier system in the body. It can have a choice to prevent certain substances from entering the brain, in order to maintain the relative stability of internal environment of the central nervous system (CNS). However, it also became an important restriction factor for the treatment of CNS diseases. Traditional Chinese medicine (TCM) had good curative effects on several kinds of CNS diseases, which illustrated that effective composition of TCM can pass through or influence the function of BBB. This paper summarized the research progress of literatures on current pharmacological and clinical trials for the effect of TCM on BBB.

Objective To evaluate the quality of medicinal materials of Lignum Dalbergiae Odoriferae in Chinese herbal medicine market. Methods Eighteen batches of commercial medicinal materials of Lignum Dalbergiae Odoriferae were identified and analyzed by macroscopical identification, thin layer chromatography (TLC), and volatile oil assay according to the Chinese Pharmacopoeia published in 2010. Visible spectrometry was used to determine the content of total flavonoids from the qualified samples. And the gas chromatography was applied to evaluate the content of nerolidol from volatile oils of the qualified samples. Results Only 33.3%of the samples met the standard of Chinese Pharmacopoeia. The total flavonoid content of the qualified samples was in the range of 21.6-29.0 mg/g. The content of nerolidol from volatile oils of the qualified samples was in the range of 294-574 mg/g. Conclusion At present, the quality of medicinal materials of Lignum Dalbergiae Odoriferae in Chinese herbal medicine market and in clinic varies greatly, and adulterants and inferior are common. The contents of chemical components in different batches of samples are significant different.
