Objective:To study the direct medical expenses for inpatients with Multiple Myeloma and explore its influencing factors. Methods:A total of 1386 hospitalization records were collected using the reimbursement claim database in Guangzhou City during the period from January 2009 to December 2011 , which covered the entire enroll-ees of Urban Employee Basic Medical Insurance ( UEBMI) and Urban Resident Basic Medical Insurance ( URBMI) . Multivariate logarithmic regression models were used to analyze the influencing factors of direct hospitalization costs. Results:During the period from 2009 to 2011 , the total costs of inpatients with Multiple Myeloma were 19319 . 16 , 17364. 76 and 21427. 44 Yuan, and the individual out-of-pocket cash payments were 7049. 37, 5216. 5 and 6475. 39 Yuan respectively. The major influencing factors on direct medical costs of inpatients with the aforesaid disease were identified to be age, health insurance type, hospital level and length of hospitalization. Besides, the proportion of drug expenses as per average occupancy rate among UEBMI and URBMI cases during three years were 61. 92% and 69. 22% respectively. Conclusion: The direct medical costs for inpatients with Multiple Myeloma are high and the medicine cost is the main component of total medical expenses. In addition, the economic burden is higher for patients with URBMI than for those with UEBMI for treating Multiple Myeloma.

In this paper, Liuwei Dihuang pill was used to study the identification of Chinese patent medicine by fluorescence sequencing typing technology. The DNA of Paeonia suffruticosa was used as template to amplify by five pair of FAM fluorescence labeling primers. Then, the amplified products were sequenced. The sequencing results were analyzed by GeneMarker V1.80 to screen the best fluorescence labeling primers. As a result, psbA-trnH fluorescence labeling primer was used to identify the raw materials of Liuwei Dihuang pill. The results showed that three kinds of raw plant medicinal materials in Liuwei Dihuang pill were able to be correctly identified by psbA-trnH fluorescence labeling primer.

OBJECTIVETo explore the effect of qidong huoxue decoction (QHD) on inflammatory factors and Toll-like receptor (TLR4) mRNA expressions in acute lung injury (ALI) rats.

METHODSTotally 50 healthy male SD rats were randomly divided into the blank control group, the lipopolysaccharide (LPS) model group, low, middle, high dose QHD groups according to body weight, 10 rats in each group. Rats in low, middle, high dose QHD groups were intragastrically administered with QHD at 4, 8, and 16 mL/kg 24, 12 h before modeling and 12 h after modeling, respectively. Normal saline was intragastrically administered to rats in the blank control group and the LPS model group. An ALI rat model was established using intratracheal instillation of LPS. Rats were killed after 24-h modeling. Then the bronchoalveolar lavage fluid was prepared. Contents of TNF-α, IL-1β, and L-10 were detected using ELISA. TLR4 mRNA expressions were determined byreal time PCR.

RESULTSCompared with the blank control group, contents of TNF-α, IL-1β , and IL-10 increased (P <0. 01), TLR4 mRNA expressions also increased in the LPS model group (all P <0. 01). Compared with the LPS model group, contents of TNF-α and IL-1β decreased (P <0. 05, P <0. 01), IL-10 levels increased (P <0. 01) , TLR4 mRNA expressions were also reduced (P <0. 01), in high and middle dose QHD groups. Compared with the high dose QHD group, con- tents of TNF-α and IL-1β increased in middle and low dose QHD groups (P <0. 05); IL-10 levels decreased (P <0. 05) in the low dose QHD group(P <0. 05), TLR4 mRNA expressions also increased in the low dose QHD group (P <0. 05). Compared with the middle dose QHD group, IL-10 levels was reduced, but TLR4 mRNA expressions increased in the low dose QHD group (P <0. 05).

CONCLUSIONSQHD had the protective effect on LPS induced ALI rats. Its mechanism might be associated with inhibiting TLR4 mRNA expressions, leading to decreased pro-inflammatory cytokines such as TNF-α and IL-β, elevated anti-inflammatory cytokine IL-10, and thereby, correcting unbalanced inflammation.
