Objective: To optimize the matrix prescription of Compound Qingfengteng Cataplasm (CQC). Methods: Taking the comprehensive senses as evaluation index, the types and dosage of the matrix were investigated by single factor. Further combined with the initial viscosity and holding viscosity index to optimize the matrix prescription of CQC by orthogonal test, and in vitro transdermal absorption experiments were carried out by Franz diffusion pool method to screen penetration enhancers. Results: The optimal formulation of CQC was as follows: 2.5 g of NP-700, 11 g of glycerin, 0.08 g of glycine aluminum, 0.08 g of tartaric acid, 0.8 g of PVP K90, 0.5 g of PVPP, 20 g of water, and 4.2 g of dry extract. 3% nitrile as a penetration agent could enhance penetration action. Conclusion: The preferred matrix prescription is practicable; CQC adhesion is moderate, no residue, paste traits, skin followability are good.

Purpose To investigate the expression level and the role of TUSC7 in human cutaneous malignant melanoma (CMM).Methods Quantitative real time-PCR (qRT-PCR) assay was performed to detect the expression of TUSC7 in 60 cases of CMM tissues,20 cases of benign nevus,4 CMM cell lines,and one normal human epidermal melanocytes.Then overexpression of TUSC7 was performed and its role in tumor progression was explored.Results TUSC7 expression was significantly downregulated in primary CMM tissues (n =60) compared to benign nevi (n =20),which were significantly downregulated in all the four melanoma cell lines,especially in A375 cells,compared with the normal melanocytes cells (all P ＜ 0.05).In comparison with the A375 cells transfected with the empty plasmid,those transfected with pcDNA-TUSC7 showed an obvious decrease in the proliferation and colony formation activity,while increase in the apoptosis rate (all P ＜ 0.05).Conclusion Our results suggested that the dysregulation of TUSC7 may play an important role in the CMM progression.

Objective To analyze the clinical characteristic s of an infant with congenital lipoid adrenal hyperplasia (CLAH),and to sequence the acute regulatory protein (steroid acute regulatory,StAR) gene of the infant patient and her pedigree.Methods Physical examination,laboratory tests,and imaging examination of the 11-month-old patient with CLAH were collected.DNA was extracted from blood samples of the patient and her parents.The 7 exons of StAR gene were amplified by PCR and then sequenced.Results Dark skin,girl vulva,and one each 1.0 cm×1.0 cm palpable lump in inguinal area bilaterally were observed.The adrenocorticotropic hormone (ACTH) was 253 pg/ml,cortisol was 27.6 nmol/L at 8 am,17-hydroxyprogesterone was 3 nmol/L.Uhrasound showed that sign of testicular ultrasonography existed in bilateral inguinal regions.Karyotype analysis showed 46,XY.Sequencing of PCR amplified fragments showed that there were two heterozygous mutations c.229C ＞ T,p (Gln77X) and C.659A＞G,p (His220Arg) of StAR gene in this patient.By rectifying the disturbance of electrolyte,and treating with hydrocortisone and 9α fludrocortisone,etc,the patient has been stable so far.Conclusion The patient presents typical clinical manifestations.Two heterozygous mutations including c.229C ＞T,p (Gln77X) from maternal and C.659A＞G,p (His220Arg) from paternal of StAR gene were detected.Wherein the c.659A＞G,p.(His220Arg) as a novel point mutation of StAR gene,has not been reported so far.

Objective To analyze the value of CT and MRI in the diagnosis of intrahepatic peripheral cholangiocarcinoma (IHPCC ). Methods 32 cases of intrahepatic peripheral cholangiocarcinoma were collected and analyzed retrospectively.25 patients underwent plain and enhanced CT scan,while 18 cases underwent plain MRI and MRCP(8 of them underwent MRI dynamic enhancement scanning).6 cases underwent plain and enhanced scan of CT and MRI simultaneously.Results 32 intrahepatic lesions were found,with CT and MRI revealing all lesions.Lesions of IHPCC showed as hypo-or iso-density on the plain CT,slightly hypo-intensity on T1 WI and uneven mild hyper-intensity on T2 WI.During arterial phase of contrast-enhanced scan,18 lesions showed as marginal mild linear enhancement,3 cases with obvious enhancement and 11 cases with no enhancement.During portal phase,venous phase and delayed scan,19 lesions showed as progressive mild-to-mod-erate uneven enhancement,while 6 cases enhanced homogeneously.25 cases showed characteristic significantly delayed enhance-ment.MRCP could display satisfactory of Intra-and-Extra-hepatic bile ducts.Other signs include intrahepatic bile ducts dilation (23 cases),intrahepatic bile duct stones (6 cases),hepatic lobe atrophy (1 5 cases),and depressed liver capsula (8 cases).Conclusion Both CT and MRI are effective methods for diagnosing of intrahepatic peripheral cholangiocarcinoma.Compared with CT,MRI seems more valuable on presentation the tumor size and border,bile duct involvement,the degree of expansion and portal vein inva-sion,etc.It is more valuable to combine CT with MRI for the diagnosis of intrahepatic peripheral cholangiocarcinoma.

ABSTRACT:Objective To investigate whether medial cerebellar nucleus may be involved in the pathogenesis of post-stroke depression (PSD)and explore the pathway that mediates this effect.Methods Healthy SD rats were randomly divided into five groups:control group,stroke group,PSD group,medial cerebellar nucleus (Med)lesion group,and superior cerebellar peduncle (xscp)lesion group.The ethological score of depression was evaluated.The neurotransmitters of Glu and GABA in the lateral hypothalamic area were detected by high performance liquid chromatography.Results Compared with those in control group,the levels of GABA and Glu expressions did not significantly differ in the lateral hypothalamic area in stroke group (P > 0.05 ).In contrast,the levels in PSD group,Med lesion group and xscp lesion group were lower than those in stroke group to different extent (P <0.01). Conclusion These results preliminarily show that medial cerebellar nucleus may participate in the pathogenesis of post-stroke depression,which may be mediated by the cerebellum-hypothalamic pathway.

Objectives To investigate the causes of short stature in Turner syndrome (TS). Methods 86 patients were di-agnosed with TS by karyotypes from 2004 to 2013. According to the deletion types of the X chromosome short arm, growth hor-mone (GH), insulin-like growth factor-1 (IGF-1) and thyroid function, the TS patients were divided into different groups and com-parison was made among groups. Results Ht SDS in three groups with different extent of the deletion of the X chromosome short arm were (-4.39±1.08), (-3.26±1.25) and (-2.84±0.15) (P<0.05). The proportion of growth hormone deifciency (GHD) in the three groups were 62.5%, 38.9%and 0%(P<0.05). Ht SDS in groups with different degree of IGF-1 level were (-4.37±1.10), (-3.82±1.07) and (-3.25±0.91) (P<0.05). There was no signiifcant difference of Ht SDS between hypothyroidism patients with and without GHD (P>0.05). Conclusions The deletion of X chromosome short arm may cause the short stature in TS. The GH-IGF-1 axis in TS is impaired, but GHD is not related to short stature in TS.
