    Abstract Objective: To observe the effect of Shengji Yuhong plaster on the wound healing after anal fistula surgery. Methods: A total of 120 patients with anal fistula who were admitted in our hospital from January, 2011 to December, 2013 for operation were included in the study and randomized into the observation group and the control group with 50 cases in each group after operation. The patients in the observation group were given external application of Shengji Yuhong plaster, while the patients in the control group were given vaselinum ribbon gauze. The patients in the two groups were given 3-week treatment. The wound area, granulation form, healing rate, healing time, and adverse reactions 1, 2, 3 weeks after operation in the two groups were compared. Results: The wound area 1, 2, 4 weeks after operation in the observation group was significantly less than that in the control group (P<0.05). The granulation form score was significantly lower than that in the control group (P<0.05). The wound repairing rate and the total effective rate were significantly higher than those in the control group (P<0.05), and the average healing time was significantly faster than that in the control group (P<0.05). Conclusions: Shengji Yuhong plaster can significantly shorten the wound healing time in patients after anal fistula surgery and is beneficial for the postoperative rehabilitation.

    Abstract The temporal variation of sedimentary organic matters (SOM) in the East China Sea (ECS) is not fully assessed due to the complicated natural and anthropogenic processes. In this study, the compositions and distributions of multi-biomarker indicators (n-alkanes, n-alkanols and specific sterols) in a long sediment core collected from the Min-Zhe fined-grained sediment zone of the ECS were systematically studied to reveal variations of SOM sources and phytoplankton records over the last decades. The results of n-alkanes and sterols have demonstrated that terrestrial plants are the dominant SOM source, with the mean proportion of 67%. The temporal variation of terrestrial to marine biomarker ratios (TMBR) agree well with that of the dominant n-alkanes and terrigenous/aquatic ratios (TAR), suggesting that the multi-biomarker indicators yield a better assessment of the SOM source input. The regular variations of terrestrial OM and phytoplankton signals during the past decades record the interaction among marine ecological effects, anthropogenic activities and natural processes (i.e., extreme climate events). As a whole, the elevated productivity of marine phytoplankton since 1952 (mainly caused by enhanced nutrient inputs owing to the intensified human activities) and the decline in the period of 2005–2011 (likely influenced by the water impoundment of the Three Gorges Dam in 2003) were well reconstructed on the basis of brassicasterol (B) and dinosterol (D) indicators in this study. The B/(B + D) ratios also reveal the changes of community structure as a result of variations in the nutrient structure controlled by anthropogenic forcing. Notably, the anomalous peak in the abundance of n-alkanes with the even carbon predominance in about 1990 is identified for the first time, which may occur at that time of the first heavy rainfall after a long drought and is probably of the origin of biomass/fossil fuel combustion.

    Abstract Although various geochemical and geophysical investigations have already indicated a great resource potential in the Xisha area of the South China Sea, the origin of organic matter and molecular evidence for tracing the migration of hydrocarbons from deep petroleum reservoirs are still lacking. In this study, systematic organic geochemical analyses, including bulk organic matter parameters and lipid biomarkers were performed for deep sediments from two cores. The C/N ratios and δ 13 C and δ 15 N values of organic matter in most of the samples, together with the maxima of short-chain n -alkanoic acids and mid-chain n -alkanols, high abundances of monounsaturated fatty acids C 18:1ω9 and C 22:1ω13 , jointly indicate the dominance of marine organic matter. n -Alkanes in sediments from core GMGS4-XH-W06B are characterized by small unresolved complex mixture (UCMs) humps, high odd/even predominance (OEP) and carbon preference index (CPI) values, clearly exhibiting characteristics of modern sediments. However, the sediments for core GMGS4-XH-W03B are featured with big UCMs, associated with OEP and CPI values around 1.0, showing signatures of petroleum hydrocarbons from high maturity sources. Considering the geologic background, the biomarker signatures are solid evidence for indicating the existence of underlying petroleum reservoirs, and may provide the valuable information for assessing the hydrocarbon resources in the Xisha area.
