Objective: To observe the clinical efficacy of heat-sensitive moxibustion for adjuvant treatment of depression in Parkinson disease and explore its mechanism. Methods: A total of 80 patients with Parkinson disease coupled with depression were randomized into an observation group and a control group, with 40 cases in each group. The control group was treated with levodopa and benserazide hydrochloride tablets and paroxetine tablets, while the observation group was treated with heat-sensitive moxibustion on the basis of the medications in the control group. The treatment course was 2 months. The Hamilton depression scale-17 (HAMD-17), unified Parkinson's disease rating scale (UPDRS) and Parkinson's disease quality of life questionnaire-39 (PDQ-39) were scored before and after the treatment, and the efficacy was evaluated after treatment. Levels of patients' serum dopamine (DA), 5-hydroxytryptamine (5-HT), tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) were detected before and after the treatment. Results: After treatment, the total effective rate of the observation group was higher than that of the control group (P<0.05). The HAMD-17 scores in the two groups decreased significantly after treatment (both P<0.05), and the score in the observation group was obviously lower than that in the control group (P<0.05). The component scores and total scores of UPDRS in both groups decreased significantly (all P<0.05), and the scores in the observation group were lower than those in the control group (all P<0.05). The score of PDQ-39 in the observation group decreased significantly (P<0.05), and was lower than that in the control group (P<0.05). After treatment, the serum DA and 5-HT levels in the observation group increased significantly (both P<0.05) and the TNF-α and IL-6 levels decreased significantly (both P<0.05), which were statistically different from those in the control group (all P<0.05). Conclusion: Heat-sensitive moxibustion has certain auxiliary effect in treating depression in Parkinson disease, significantly improving clinical symptoms and the quality of life, which may be related to the up-regulation of DA and 5-HT levels and down-regulation of TNF-α and IL-6 levels.

OBJECTIVE: To analyze the general and forensic pathological characteristics of death due to fat embolism syndrome (FES) and to provide reference data for forensic identification. METHODS: Twenty autopsy cases due to FES were selected from the forensic center of a medical college from 1999 to 2012. The general and forensic pathological characteristics such as the ways and types of injuries, clinical manifestation and the pathological changes were summarized. RESULTS: Fat embolism mainly occurred after long bone fracture or a large area of soft tissue injury with the majority of cases being fat embolism of lung and occasional cases being combined embolisms of lung and brain as well. The onset of symptoms appeared shortly after the injury or surgery. Lipid droplets could be observed within small pulmonary vessels and verified by special staining. CONCLUSION There are particular characteristics in death due to FES in concern with types of injuries, onset of symptoms and pathological findings. In order to find out the direct evidence of FES, special staining (oil red O staining) can be used in the forensic identification.

Astragalus membranaceus var. mongholicus and Hedysarum polybotrys belong to different genera, but have similar drug efficacy in traditional Chinese medicine theory, and H. polybotrys was used as the legal A. membranaceus var. mongholicus previously. In this study, similarities and differences between them were analyzed via their ITS/ITS2 fragments information. The ITS (internal transcribed spacer) regions were amplified using polymerase chain reaction and then sequenced in two-way. The alignment lengths of ITS regions were 616 bp, in which 508 loci were consistent, and 103 loci were different, accounting for 82.47% and 16.72% of the total ITS nucleotides in length, respectively. As genotype determines phenotype, 1HNMR-based metabolomic approach was further used to reveal the chemical similarities and differences between them. Thirty-four metabolites were identified in the 1H NMR spectra, and twenty-seven metabolites were the common components. Amino acids, carbohydrates and other primary metabolites were similar, while a large difference existed in the flavonoids and astragalosides. This study suggests that A. membranaceus var. mongholicus and H. polybotrys show similarities and differences from molecular and chemical perspectives, which has laid a foundation for elucidating the effective material basis of drug with similar efficacy and resources utilization.

To observe the expression of N - cadherin and fibronectin in retinal pigment epithelium ( RPE) cells in vitro under high glucose conditions, furthermore, to explore the effects of high glucose on epithelial -mesenchymal transition (EMT) in RPE cells.
●METHODS: Human RPE (hRPE) cells were cultured in vitro. Containing a final concentration of 60mmol/ L glucose was used for high glucose treatment. The cells were divided into normal glucose group (5. 5mmol/ L, NG) and high glucose group (24, 48 and 72h) respectively. The expression of N - cadherin and fibronectin in hRPE cells were evaluated by immunofluorescence and real -time PCR.
●RESULTS:RPE cells became disorganized and swollen over time under high glucose conditions, especially in 72h subgroup. lmmunohistochemical analysis revealed that the expression of N - cadherin in RPE cells under high glucose conditions was decreased compared with that in the control group, while the expression of fibronectin was increased. Real - time PCR results showed that the expression of N - cadherin mRNA in high glucose group was decreased at 24h compared with that in the control group, and declined markedly at 72h ( F = 12. 252, P =0. 000). There were no significant differences between the control group and the high glucose group at 24h, while the differences between the control group and the high glucose group (48 and 72h) were significant respectively (P < 0. 05 ). Meanwhile, the expression of fibronectin mRNA in RPE cells was increased in high glucose group at 24h, and reached the peak at 72h (F = 50. 543, P = 0. 000). There were no significant differences between the control group and the high glucose group at 24h. Compared with the control group, the expression of fibronectin mRNA in hRPE cells was increased significantly in high glucose group (48 and 72h) respectively (P= 0. 000, P= 0. 000).
●CONCLUSlON: The expression of epithelium marker N-cadherin is down - regulated under high glucose conditions in hRPE cells in vitro. Meanwhile, the expression of mesenchymal maker fibronectin is induced and appeared to EMT changes. Results of this study will enrich our growing understanding in proliferative diabetic retinopathy and hopefully lead to novel insights for the pathogenesis and therapeutic treatments.
