OBJECTIVETo discuss the efficacy of the myogenic elephant skin cream combining with VSD for treating severe bedsores.

METHODSTwenty-nine cases of III and IV degree bedsores were treated from June 2009 to June 2013. Among them, 15 cases were treated by myogenic elephant skin cream combined with VSD (VSD group) including 7 males and 8 females with an average age of (69.0±5.3) years old ranging from 17 to 96 years;other 14 cases were treated by the treatment of conventional dressing change (control group) including 6 males and 8 females with an average age of (71.0±4.2) years old ranging from 40 to 86 years. At 7, 14, 21, 28 d after treatments, specimens of wound two groups were respectively taken to examine immunohistochemical CD34 adopted SABC, the number of wild vascular cross were observed as capillary density value under high magnification microscope. It was used to assess the hyperplasia of granulation tissue of wound. The capillary density value and the visual wound observation were indicators for evaluation of clinical efficacy.

RESULTSSeventeen of 19 cases got complete data of specimens of wound at 7, 14, 21, 28 d,included 9 cases of VSD group,8 of control group. In the microscope view, the capillary density of VSD group was higher than that of control group significantly (P<0.05), it showed the application of VSD technology improved hyperplasia of granulation tissue much faster than conventional dressing change. In VSD group, 13 cases with 15 wounds healed, 2 cases with 3 wounds improved; in control group,3 cases with 3 wounds healed,7 cases with 9 wounds improved, 4 cases with 5 wounds were unhealed.

CONCLUSIONUsing the VSD technology with continuous high pressure suction to clean the drainage of wound and lacuna thoroughly can effectively control infection,promote the growth of granulation tissue, and then applying myogenic elephant skin cream to improve partial blood supply while prompting rapid growth of new granulation tissue and epithelial cell. The risk of this treatment is low,and the course of treatment is short, this provides a safe and effective method for treating bedsores.

OBJECTIVETo observe the effect of Chinese herbal extract HuNan A-1 (HNA-1) on the thymic output function in Simian immunodeficiency virus (SIV) chronically infected rhesus macaques.

METHODSEight Chinese rhesus macaques had been infected by SIVmac239 for 16 to 21 months, and then they were randomly divided into the treatment group and the control group, 4 in each group. Monkeys in the treatment group were administered with HNA-1 by gastrogavage, once daily for 2 successive months, while those in the control group were administered with equal volume of normal saline by gastrogavage, once daily for 2 successive months. The general condition and body weight of monkeys were observed. Plasma viral loads were detected using real-time fluorescent quantitative PCR assay. CD4 percentages and counts, as well as naive CD subsets were detected using flow cytometry. T-cell receptor excision circles (TREC) were detected using real-time fluorescent quantitative PCR assay. The thymus tissue was pathologically observed using routine HE staining. The correlation between lesions of the thymus tissue, CD4 counts, naive CD counts, and TREC were analyzed.

RESULTSThere was no statistical difference in body weight, viral loads, absolute CD ratios between the two groups after treatment (P > 0.05). The altered TREC multiple showed an obvious decreasing tendency in the control group, while it showed an increasing tendency in the treatment group (P < 0.05). In both groups, destroyed structures of the thymus tissue could be seen, filled with pink unstructured material. Increased connective tissues, lowered connective cell density, and confused arrangement could also be seen in the two groups, with no obvious difference. TREC contents were positively correlated with naive CD4 counts after removing extremum (r = 0.926, P = 0.001). Naive CD4 counts were positively correlated with CD4 counts (r = 0.961, P = 0.005).

CONCLUSIONSTREC content determination, as a marker of newly thymic emigrants, could be taken as a testing method for evaluating the thymic output function. Besides, HNA-1 treatment increased the thymic output significantly in SIV chronically infected monkeys. Correlation existed among TREC contents, naive CD4 counts, and pathologies of thymus tissues, especially in late infection stage.
