Objective: By taking the holism and differentiation concepts of traditional Chinese medicine (TCM) as the guidance, physical, mental and workplace factors were recruited in the observation of depression in employees, and were systematically classified to establish a workplace-related Liver Meridian-depression scale, for providing an evaluation index for depression in employees. Methods: NVIVO 11 software was adopted to assort ancient TCM classics. Based on the holism and differentiation concepts of TCM and well-developed scales, the item pool was determined via brain storm and screened by Delphi method after classified; a Wechat questionnaire was handed out 240 times via the online system 'Wen Juan Xing', and the results were statistically analyzed by the SPSS 17.0 version software. Results: Five dimensions consisting of 80 items were obtained after classification, and 60 items were selected by Delphi method; a total of 216 questionnaires were returned and the return rate was 90%. Of which, 215 questionnaires were valid ones, and the valid rate was 99%. By exploratory factor analysis (EFA), 44 items were obtained, and the aggregate split-half reliability coefficient was 0.922. The Cronbach's alpha coefficient for the five dimensions, i.e. Liver Meridian, relevant meridians, basic psychological activities, work cognition and emotional reactions, was respectively 0.841, 0.842, 0.914, 0.836 and 0.839, indicating a content internal consistency. The score of each item was highly correlated with the corresponding dimension, and the intercommunity was between 0.474 and 0.801. Nine factors were generated, 2 in the dimension of Liver Meridian, 3 in the dimension of relevant meridians, 2 in the dimension of basic psychological activities, 1 in the dimension of work cognition, and 1 in the dimension of emotional reactions, and the load of each factor was between 0.438 and 0.859. The reliability and validity of the scale were well examined. Conclusion: The scale can be applied to evaluate the qi activities of Liver Meridian and depression symptoms related to workplace.

Four specific salt-tolerant fungi for dissolving phosphate rock (FM) w ere isolated from the coastal saline soils. It was found that the biomass and a b ility to release phosphate from the materials decreased with increasing of the N aCl content. During pH7.0～8.5, the biomass and ability of to release phospho rus from the materials of FM1 decreased sharply with pH rising, but the FM2 and FM4 decreased not considerably, optimal pH for FM3 was at pH8.5. At pH9.0, the bi oma ss and ability of to release phosphorus from the materials decreased quickly. F M2 was stable at alkaline and high salt content condition.

Objective To explore the relationship between fetal heart size and gestational weeks (GW). Methods The size of left atrium (LA), right atrium (RA), left ventricle (LV), right ventricle (RV), aorta (AO), pulmonary artery (PA), foramen ovale (FO), heart area (HA), thoracic area (TA), heart circumference (HC) and thoracic circumference (TC) were measured for 512 fetal hearts at 14-39 GW. The relationship between GW and the measurement was evaluated. Results The size of fetal heart chambers, AO, PA and ventricular septum (IVS) increased with the development of GW. The PA/AO, LA/RA, LV/RV, HC/TC and HA/TA were stable compared with different GW. Conclusion Fetal heart chambers increase with the development of GW. HA is correlated well with GW.

OBJECTIVETo explore the analgesic mechanism of small knife needle for treating transverse process syndrome of the third vertebra (TPSTV) by observing peripheral and central changesof β-endorphin (β-EP) and enkephalin (ENK) contents.

METHODSTotally 30 Japanese white big-ear rabbits of clean grade were divided into 5 groups according to random digit table, i.e., the normal control group, the model group, the small knife needle group, the electroacupunture (EA) group, and the small knife needle plus EA group, 6 in each group. The TPSTV model was established by inserting a piece of gelatin sponge into the left transverse process of 3rd lumbar vertebrae. Rabbits in the small knife needlegroup were intervened by small knife needle. Those in the EA group were intervened by EA at bilateralWeizhong (BL40). Those in the small knife needle plus EA group were intervened by small knife needleand EA at bilateral Weizhong (BL40). Contents of β-EP and ENK in plasma, muscle, spinal cord, and hypothalamus were determined after sample collection at day 28 after modeling.

RESULTSCompared with the normal control group, contents of β-EP and ENK in plasma and muscle increased significantly, and contents of β-EP and ENK in spinal cord and hypothalamus decreased significantly in the model group (P < 0.05, P < 0.01). Contents of β-EP and ENK approximated normal levels in the three treatment groups after respective treatment. Compared with the model group, the content of β-EP in muscle decreased, and contents of β-EP and ENK in hypothalamus increased in the three treatment groups after respective treatment (P < 0.05). There were no significant difference among the three treatment groups (P > 0.05).

CONCLUSIONSSmall knife needle treatment and EA had benign regulation on peripheral and central β-EP and ENK in TPSTV rabbits. Small knife needle treatment showed better effect than that of EA.

OBJECTIVETo observe the dynamic expression of calcium-sensing receptor(CaSR) in myocardium of diabetic rats.

METHODSThirty male Wistar rats were randomly divided into 3 groups including control, diabetic-4 week and diabetic-8 week groups(n = 10). The type 2 diabetes mellitus models were established by intraperitoneal injection of streptozotocin (STZ, 30 mg/kg) after high-fat and high-sugar diet for one month. The cardiac morphology was observed by electron microscope. Western blot analyzed the expression of CaSR, phospholamban (PLN), a calcium handling regulator, and Ca+-ATPase(SERCA) in cardiac tissues.

RESULTSCompared with control group, the expressions of CaSR and SERCA were decreased, while the expression of PLN was significantly increased in a time-dependent manner in diabetic groups. Meanwhile diabetic rats displayed abnormal cardiac structure.

CONCLUSIONThese results indicate that the CaSR expression of myocardium is reduced in the progression of DCM, and its potential mechanism may be related to the imnaired intracellular calcium homeostasis.
