China Pharmacy 2015;(23):3204-3205
OBJECTIVE:To provide reference for the rational use of TCM injections. METHODS:The related data of using TCM injections was drawn from May 2009 to May 2014. And the data of 5 TCM injections,including Shengmai and Shenmai in-jection,were statistically analyzed,the indications of 8 TCM injections,including Shengmai and Shenmai injection,were also sta-tistically analyzed. RESULTS:In solvents evaluation,the 5 TCM injections were used 501 times,in which 391 times(78.04%)of the solvents used were rational,381 times(76.05%)of the solvent doses used were rational;in clinical indications evaluation,the 8 TCM injections were used for 2 579 patients,in which 1 120 cases were in accordance with the instructions while the other 1 459 cases were not,the qualification ratio was 43.43%. CONCLUSIONS:There were still some problems in using TCM injection in our hospital in the aspects of solvent as well as indications.

Objective To explore the clinical characteristics, treatment and outcomes of patients with panniculitis. Methods Clinical data of patients with panniculitis admitted to our hospital were analyzed and followed up. The disease was classified into two sub-types: cutaneous type and systemic type. The clinical profile and treatment as well as the outcomes were compared. Results The mean follow up time of 61 in-patients with panniculitis was 49.2 months (range: 2~216 months). Remission could be achieved in 17 patients, recurrent episodes happened in 26 patients. Eighteen patients turued out to be diffuse connective tissue disease (CTD), hematological disorders, malignant tumors and tuberculosis during follow-up. The age at sympton onset was 33±17 years old in 43 patients with primarily panniculitis which eutaneoua sub-tye was 12 patients and systemic sub-tye was 31 patients. The male: female ratio was 1:15. Patients with systemic sub-type were associated with liver (25 patients), spleen (23 patients), respiratory system (11 patients), kidney (12 patients), and circulatory (3 patients) system involvement. Nine patients with systemic sub-type presen-ted white blood cell decrease while none of in the cutaneous sub-type. The difference was significant (P=0.044). Biopsy of the lesions had shown nuclear dust in 16.3% of primarily panniculitis patients. Conclusion Pannieulitis can associate with systemic rheumatic diseases, malignant tumors, hematological disorders and tuberculosis. The main systemic involvements with systemic sub-type are liver and spleen, and may have whiteblood cell decreasing. Some patients could achieve remission when treated with corticosteroids and/or immunosuppressive drugs. However,the majority of patients will have recurrences when corticosteroids is tapered.

Purpose To explore the relationship between the mutations of epidermal growth factor receptor ( EGFR) and KRAS genes and clinicopathological characteristics in patients with non-small cell lung cancers (NSCLC). Methods Clinical samples from 431 NSCLC patients were obtained for EGFR and KRAS gene analysis. PCR based direct DNA sequencing was used to investigate mutations in exon 18-21 of EGFR gene and codon 12 and 13 of exon 2 of KRAS gene. Results The overall EGFR mutation rate of primary NSCLC was 53. 6% (231/431) in this study cohort and eight cases showed double EGFR mutations. Mutation rates in female and male were 65. 2% (122/187) and 46. 9% (98/209), respectively. The mutation rate was higher in patients with non-smokers and adeno-carcinoma and adenosquamous carcinoma subtypes than in their counterparts (P<0. 05), with the percentage of 57. 2% (124/216), 60. 3% (199/330), 42. 9% (6/14), respectively. In squamous cell carcinomas and other subtypes, EGFR mutation rates were 11. 6% (5/43) and 11. 1% (1/9), respectively. The EGFR mutation types included exon 18 point mutations (4. 0%, 9/227), exon 19 deletion mutations (4. 5%, 101/227), exon 20 insert or point mutations (9. 7%, 22/227) and exon 21 point mutations (41. 4%, 94/227). Activating mutations of KRAS gene were detected in 7. 8%(31/396) of NSCLC. Twenty-eight patients showed codon 12 mutations ( G>T, G>A, G>C) , and three patients had codon 13 mutations ( G>A, G>T) . Most of these mutations were G to T transversion (64. 5%, 20/31). Conclusion Polymerase chain reaction-direct sequencing is a reliable and effective method for the detection of the EGFR and KRAS gene mutation in NSCLC patients. The mutation rate of EGFR is higher in Chinese patients, especial-ly in non-smoking female patients with adenocarcinoma.

Prepulse inhibition ( PPI) is the suppression of the startle reflex when the startling stim-ulus is preceded by a non-startling stimulus ( the prepulse) . It is an operational measurement of sensorimotor gating mechanism to help the brain adapt to the complex environment,which could be top-down modulated by attention and other higher cognitive processes. Deficits of PPI and the top-down modulation of PPI are closely related to psychiatric diseases. Research papers published from January 2001 to October 2016 related to PPI in psychiatric disorders were searched in the Chinese and English databases. Results showed that schizo-phrenic patients and their relatives showed deficits in baseline PPI as well as the attentional modulation of PPI,and more importantly,the attentional modulation of PPI rather than the baseline PPI was more related to the symptom severity. Patients with Tourette'' s syndrome showed PPI impairment,while patients with obsess-ive compulsive disorder had lower levels of PPI. PPI deficits in bipolar disorder patients were gender-depend-ent. Studying PPI and the top-down modulation of PPI could provide a basis to study the interaction of senso-ry processing and attention,and facilitate the researches of neural mechanism underlying the deficits of senso-ry gating. To establish advanced paradigms of PPI,new cognitive components could be introduced,such as at-tention,emotion,motor control,compulsivity and so on,thus improving the specificity of PPI test and promo-ting the PPI test as new biomarker and endophenotype in various psychiatric disorders.

Background and purpose: Uveal melanoma (UM) is the most common primary intraocular malignancy in adult. Due to a high tendency for early metastasis the treatment of UM is very difficult. This study aimed to explore an effective approach for the treatment of patients with UM, we designed a strategy that combined HtrA2 gene therapy and radiation therapy. Methods:pIRES-Egr1-Omi/HtrA2 (pEgr1-HtrA2) recombinant plasmids were constructed and transfected into human UM cells (OCM-1) in vitro. The transfected cells were exposed to irradiation. HtrA2 mRNA and protein levels were detected by qRT-PCR and Western blot respectively. Assays that evaluated the apoptosis inducibility caused by HtrA2 gene therapy combined with radiation was performed by lfow cytometry. Followingly, the effects of HtrA2 overexpression on the in vitro radiosensitivity of uveal melanoma cells were investigated by clonogenic formation assay. The in vivo effects of HtrA2 gene therapy combined with radiation therapy were evaluated in different groups. Results:The recombinant plasmids could be successfully transferred into OCM-1 cells and transfection of pEgr1-HtrA2 plasmids combined with radiotherapy caused dramatically elevation of HtrA2 compared with non-irradiation cells in mRNA and protein levels, which was associated with increased apoptosis.Furthermore, we observed that the transfection of pEgr1-HtrA2 could significantly enhance radiosensitivity of OCM-1 cell in vitro. In mice bearing xenograft tumors, pEgr1-HtrA2 combined with radiation therapy signiifcantly inhibited tumor growth compared with the other treatment groups (P<0.05). Conclusion:Our ifndings indicate that radiation-inducible gene therapy may have potential to be a more effective and speciifc therapy for uveal melanoma because the therapeutic gene can be spatially or temporally controlled by exogenous radiation.

The expressions of estrogen receptor (ER) α,ERβ1,and ERβ2 in thyroid carcinoma,thyroid adenoma,and adjacent normal thyroid tissue were determined by RT-PCR and immunohistochemistry,and the relationship of expression levels of three ERs and the main clinical pathologic parameters were evaluated.The result showed that ERα mRNA expression in papillary thyroid carcinoma(PTC) tissues was significantly higher than adjacent normal tissue,while,ERβ2 mRNA expression in PTC tissues was significantly lower than normal tissue ( P<0.05 ).The positive expression of ERβ1 and ERβ2 in the thyroid carcinoma was related with the histological variant of carcinomas; the ERβ2 expressions were related with the lymph node metastasis and TNM staging of the carcinomas.These results suggest that the decreased ERβ2 expression may induce proliferation and carcinogenesis of thyroid follicular epithelial cells as well as progression of the carcinoma,and is a powerful prognostic indicator.
