The epidural venous plexus is considered as a cause of low back and leg pain but has been neglected for a long time. As an auxiliary drainage system of the vena cava, the epidural venous plexus plays an important role in the circulation of body fluids, and its tortuous expansion may lead to clinical symptoms similar to a herniated disc or spinal stenosis, by compressing nerve roots or dura. Due to the lack of specificity of imaging findings, it is difficult to distinguish accurately from disc herniation or spinal stenosis. The epidural venous plexus is tortuous and thin-walled, which is easy to be broken during the operation that resulted in obscuring the surgical field and leading to other complications such as postoperative hematoma. Despite researches of epidural venous plexus have been carried out for years, details are still left unknow. We hereby reviewed the latest research progress of the epidural venous plexus including anatomical structure, morphological characteristics, clinical significance and imaging examination.

AlM:To evaluate the efficacy of combined pranoprofen eye drops and artificial tears on the treatment of mild to moderate dry eye syndrome after trabbeculectomy.METHODS:This prospective case control study included 63 cases (63 eyes) of patients with mild to moderate dry eye syndrome after trabbeculectomy in our hospital from November 2013 to June 2013. All subjects were randomly divided into two groups. Observation group was treated with combined pranoprofen eye drops and artificial tears and control group received simple artificial tears marking the eyes at 1, 2, 4wk. The patient's symptoms, signs, BUT, S▏t, and FL were observed before treatment and 1, 2, 4wk after treatment.RESULTS: After 2wk, the symptoms of observation group were improved, there was statistically significant difference (P<0. 05). FL difference of each group was statistically significant ( P<0. 05 ); After 4wk, symptoms and signs were improved. There was statistically significant difference ( P < 0. 05 ). The BUT of the observation group and corneal FL scores of two groups showed significant differences (P<0. 05). CONCLUSlON: Artificial tears joint pranoprofen eye drops has good curative effect in the treatment of mild to moderate dry eye syndrome after trabbeculectomy.

Langerhans cell tumor is a kind of tumor that originates from Langerhans cells (LC) and maintain their specific phenotype profile and ultrastructural features. Based on cell morphology, immunohistochemical and ultrastructural characteristics, Langerhans cell tumor has two main subcategories: Langerhans cell histiocytosis (LCH) and Langerhans cell sarcoma (LCS). LCH is a benign clonal proliferative disease of the LC, whereas LCS is an extremely rare neoplastic proliferation of Langerhans cells with overtly malignant cytologic features and spreads aggressively, which is considered to be a high level malignant type of LCH. Both LCH and LCS can involved various tissues and organs and have complex and diverse clinical manifestation, which cause different severity. The diagnosis depends on histopathological morphology and immunohistochemistry; the electron microscopy was used to assists diagnosis when necessary. The treatment includes surgery, chemotherapy, radiotherapy, immunotherapy and hematopoietic stem cell transplantation, etc, but lack of generally accepted optimal treatment options currently, individualized treatment is needed. The prognosis of LCH is primarily related to the number of damaged organ, while LCS has a poor overall prognosis as its invasion and rapid progress. This article reviews the pathogenesis, clinical manifestations, diagnosis, treatment and prognosis of both LCH and LCS.

OBJECTIVETo introduce the clinical manifestations and laboratory tests of adult onset of primary hemophagocytic syndrome (HPS), and to investigate the essentials of diagnosis and the genotype characteristics in adult onset patient.

METHODSThe definite diagnosis of HPS was made according to HLH-2004. Exons of PRF1, STX11, UNC13D, SH2D1A and RAB27A genes coding region were amplified using polymerase chain reaction.

RESULTSA 48-year-old man was admitted to our hospital because of recurrent fever, pancytopenia and lymph node enlargement. His laboratory test revealed bone marrow hemophagocytosis, elevated ferritin level (2000 µg/L), reduced level of NK cell activity (20.13%) and elevated soluble CD25 level (12277 U/ml). Based on the HLH-2004 diagnostic criteria, the patient was diagnosed as HPS. The patient had viral infection, and no other primary disease was identified that would cause HPS. The patient responded poorly to anti-viral therapy. DNA sequencing was used to confirm that perforin gene mutations might be one of the causes of the patient suffered from primary HPS.

CONCLUSIONSAlthough primary HPS usually affects infants and young children, it also occurred in teens and adults. It is essential to perform genetic screenings to patient whose illnesses recur with unknown causes. In addition, detection of molecular genetic alterations can be used to distinguish primary HPS from acquired HPS.

Objective To investigate the effect of miR-200 a mimic on transforming growth factor β1-mediated acti-vation and collagen secretion of rat pancreatic stellate cells .Methods PSCs were isolated and cultured from pan-creatic tissue and identified by desmin , GFAP and α-SMA immunofluorescence staining .PSCs of 2nd generation were divided into control group , TGF-β1 group, TGF-β1+miR-NC group and TGF-β1+miR-200a mimic group.α-SMA and collagen Ⅰ protein were measured by Western blot and immunofluorescence staining .The mRNA ofα-SMA and collagen Ⅰ and the expression of miR-200a were detected by quantitative real-time PCR.Results TGF-β1 stimulates the activation of PSCs and promote collagen synthesis in time-dependment manner ( P<0.05 ) . After transfection of the mimic , treating with the same concentration of TGF-β1, the expressions of protein and mR-NA of both α-SMA and collagen Ⅰ decreases significantly ( P<0.01 ) .Conclusions Over-expression of miR-200 a significantly attenuates α-SMA activity and further affects the collagen synthesis of TGF-β1-dependent activa-tion of PSCs.The mechanisms are potentially related to the biological effects of TGF-β1.

Objective To explore the expression of urothelial carcinoma-associated 1 ( UCA1 ) in pancreatic cancer cell lines and its influence on the invasion and metastasis of the pancreatic cancer cells .Methods The expression of UCA1 in pancreatic cancer tissues and paired adjacent normal tissues ( 11 cases ) and 5 pancreatic cancer cell lines was analyzed by real-time PCR.The level of UCA1 in BxPC-3 was knocked down by small interfering RNA . The ability of invasion and migration in vitro of transfected BxPC-3 was detected by Transwell invasion assay and wound healing assay .The protein levels of MMP-2 and MMP-9 were measured by Western blot experiment .Results The expression level of UCA1 in pancreatic cancer tissues was higher than that in paired adjacent normal tissues , and UCA1 differentially expressed in 5 pancreatic cancer cell lines .Down-regulation of UCA1 by siRNA suppressed the expression of MMP-2 and MMP-9 in BxPC3, and dramatically impaired the ability of invasion and migration of BxPC-3.Conclusions UCA1 is over-expressed in pancreatic cancer , and down-regulation of UCA1 attenuates the capacity of invasion and metastasis in vitro of BxPC-3 by decreasing MMP-2 and MMP-9.

OBJECTIVE:To discuss the way to realizing clinical pharmacists’prescribing rights,and to provide reference for the revise of related policies and regulations. METHODS:The clinical pharmacists prescribing rights and its necessity were inter-preted. Referring to pharmacists’prescribing rights in Canadian limited prescription mode,British dispensatory mode,United States consultative prescription mode,clinical pharmacists’prescribing rights in China were expounded. RESULTS & CONCLU-SIONS:It is necessary and feasible to achieve clinical pharmacists’prescribing rights in China. Clinical pharmacists’prescribing rights can be realized and the pharmaceutical role of clinical pharmacists can be played through conducting clinical pharmacist pre-scription training,establishing chronic disease,common disease,mild disease and other disease dispensatory,gradually revising the concept of“prescription”and“prescribing rights”,promoting the legislation of pharmacists and clinical pharmacists’prescrib-ing rights,promoting the realization of the prescription right of clinical pharmacist,prompting clinical pharmacist to play the role of pharmacy.
