Objective To observe the effects of a decoction of buzhong yiqi in conjunction with rehabilitation training in relieving post-stroke fatigue.Methods A group of 115 stroke patients was enrolled and randomly divided into a simple rehabilitation group and a combination therapy group.Both groups received conventional rehabilitation treatment and appropriate treatment of any primary diseases.In addition,those in the combination therapy group were given a decoction of buzhong yiqi twice daily for a total of 4 weeks.EMG signals,subjective evaluations of fatigue severity,active rehabilitation exercise duration,motor function and ability in the activities of daily living (ADL) were assessed before treatment and after 4 weeks of treatment.The slope of the surface electromyogram's mean power frequency (KMPF) and median frequency (KMF) were used to quantify fatigue.Subjective fatigue severity was estimated using a fatigue severity scale (FSS).The active rehabilitation exercise lasted,on average,90 minutes daily.The Fugl-Meyer assessment (FMA) was used to evaluate motor function and the modified Barthel index (MBI) ADL ability.Results There were no statistically significant differences between the groups before treatment.After 4 weeks of treatment all the outcomes in both groups had improved (except the FSS scores of the simple rehabilitation group).The KMPF,KMF,FSS,exercise duration,FMA scores and MBI scores in the combination therapy group were all significantly better than those in the simple rehabilitation group.Conclusion Taking buzhong yiqi can significantly improve the clinical effects of conventional rehabilitation training on post-stroke fatigue.It helps relieve fatigue,improve active participation in rehabilitation exercise,and also improve motor function and ADL ability.

Objective To observe the sub-chronic effects of low doses of arsenic poisoning in rabbits exposed to different periods on some of the serum enzymes and biochemical indicators, and to provide the basis for screening of meaningful hematologic indicators for early diagnosis of arsenic poisoning. Methods Twelve adult rabbits,weighing 2.0 - 3.5 kg, were randomly divided into four groups, 3 in each group, and they were fed with drinking water containing sodium arsenite 0(control),0.01,0.05,0.25 mg/L, respectively. Serum alanine aminotransferase (ALT), aspartate amino transferase (AST), alkaline phosphatase (ALP), γ-glutamyl transacylase (y-GT), total protein(TP), albumin(ALB), globulin(GLP), and ALB/GLP of rabbit were measured by SYSMEX-180 automated biochemistry analyzer after 8 weeks and 12 weeks exposure. Results The results showed that ALT in 0.05 mg/Lgroup of 12 week[(60.00 ± 4.14)U/L]increased significantly compared with the control[(41.50 ± 2.12)U/L, P ＜0.05];AST in 0.25 mg/L group of 8 week and 12 week[(46.50 ± 3.21 ), (52.33 ± 3.81 )U/L]increased significantly compared with the control[(21.33 ± 3.53), (29.50 ± 3.23 )U/L, all P ＜ 0.05];ALP in 0.05 mg/L and 0.25 mg/L group of 12 week [(78.68 ± 4.85 ), ( 103.00 ± 7.83 ) U / L]increased significantly compared with the control [(45.50 ± 5.50)U/L, all P ＜ 0.05];γ-GT in 0.05 mg/L group of 12 week[(19.33 ± 7.50)U/L]increased significantly compared with the contro1[(8.50 ± 3.53)U/L, P＜ 0.05]. TP, ALB, GLP, ALB/GLP of different groups of 8 week and 12 week were not significantly different statistically(F= 0.77,0.02,0.16,3.14 and 0.51,0.29,0.41,0.52, all P ＞ 0.05). Conclusions Zero point zero five mg/L and higher doses of sub-chronic arsenic exposure has some major damage to the liver. Compared with other serum enzymes and the biochemical indexes, serum AST is a early sensitive indicator of liver injury of the arsenic poisoning.

BACKGROUND: There is nearly no muscle tissue with satisfactory function and appearance applying in clinical repair and construction of injured muscles to date. OBJECTIVE: To investigate the feasibility of applying autologous fascia as a scaffold to construct muscle in vivo. DESIGN, TIME AND SETTING: The randomized, self-matched control experiment was carried out between January 2004and June 2006 at Department of Burns & Plastic Surgery, Second Hospital of Shenzhen, Shenzhen, Guangdong Province, China MATERIALS: Twenty-eight healthy New Zealand rabbits, weighing (1.7±0.5) kg, without sex restriction, establishing middle part defect model of anterior tibial muscle of rabbit hind legs. METHODS: One hind leg of each rabbit was randomized to the experimental group (n=28), the other hind leg was assigned to one of 3 control groups, scaffold-connected group (n=10), muscle particle implant group (n=10) and blank control group(n=8). In experimental group, the defect was connected with an autologous fascial scaffold and filled with the mutilated muscle particles, and subcutaneous tissue and skin were sutured in situ. In scaffold-connected group, the treatments were same to the experimental group only except muscle particle implantation. In muscle particle implant group, the defect was filled with muscle particles but without fascial scaffold and other treatments were same to the experimental group. The defect in blank control group received no treatment. MAIN OUTCOME MEASURES: The success rate of muscle transplantation, histological and ultra structural observation,and immunohistochemical identification of desmin were observed at 2, 3, 4, 6 and 9 weeks after operation. The middle parts of samples were also harvested for relative quantitative analysis of α-actin cDNA using reverse transcription-polymerase chain reaction in the experimental group and scaffold-connected group.RESULTS: In experimental group, 1 muscle broke near the proximal junction, the other 27 succeeded and the appearance of healed defects became near normal gradually. In scaffold-connected group, 4 muscles broke, 6 muscles still depressed in defect area; in muscle particle implant group and blank control group, the defects had no change. In experimental group, a large quantity of skeletal muscle satellite cells proliferated, which reached peak at 2-3 weeks, cells attached to the ends of fibrous connective tissue; in scaffold-connected group only fibrous connective tissue was seen. lmmunohistochemistry showed that 85% cells in experimental group were desmin-positive, while the positive rate in scaffold-connected group was < 25%. The relative quantitative analysis of α -actin cDNA showed that there were significant differences between the experimental group and scaffold-connected group at different time points(P < 0.05).CONCLUSION: The success rate of repairing muscle defect with autologous fascial scaffold reached 93.33%, which indicates that it is feasible to promote muscle regeneration with autologous fascial scaffold.

AIMTo analyze and compare the constituents of the volatile oil of Pogostemon cablin collected from different regions of cultivation and harvesting times in order to evaluate the quality of Shipai Huoxiang and to expound the chemical intension of Pogostemon cablin.

METHODSThe combination of GC and MS.

RESULTSThe volatile oil compositions of Herba Pogostemonis collected from various of cultivation regions and harvesting times are obviously different. Based on the chemical differences of the volatile oil compositions, Pogostemon cablin is divided into two chemotypes, Pogostone-type and Patchouliol-type. The former was cultivated in Guangzhou and Gaoyao regions, locally named as "Shipai Huoxiang"; the latter was locally named as "Hainan Huoxiang", cultivated in Wuchuan, Suixi and Leizhou regions of Guangdong Province and Wanning region of Hainan Province. The Pogostone-type contains rich oxygenated components, especially pogostone in the volatile oil compositions and poor non-oxygenated composition with patchouliol. The above chemical data may be used as evaluation standard for the authentic Shipai Huoxiang. The Patchouliol-type contains similar quantities of oxygenated and non-oxygenated composition, especially rich patchouliol with poor pogostone in oxygenated compositions, rich delta-guaiene and alpha-guaiene in non-oxygenation compositions. The contents of volatile oil and their constituents were varied due to different harvesting time. The yields of pogostone and volatile oil of Shipai Huoxiang was higher in July. The quality of the samples collected in this month was better.

CONCLUSIONAccording to the volatile oil compositions, there are two chemotypes (Pogostone-type and Patchouliol-type) in Pogostemon cablin plant. These two chemotypes correspond to the genotypes of plastid matK gene and nuclear 18s rRNA gene by cluster analysis.

OBJECTIVETo investigate the occupational exposure levels of dust in new suspension preheated dry process (NSP) cement production line and put forward rectification measures for dust-exposed posts, and to provide ideas for the modern cement production enterprises in dust control and occupational health management.

METHODSOccupational health field investigation combined with field test were used to measure the time-weighted average concentration (C(TWA)) of the dust in the workplace. Rectification measures were taken for the dust-exposed posts with unqualified dust concentration, and the protective effects of dustproof facilities in the rectified workplace were evaluated.

RESULTSThe field investigation revealed incompletely closed dustproof facilities, improperly set dust hoods, excess of dust leakage points, and other problems in the dust-exposed posts of an NSP cement production line before rectification, and the dustproof facilities could hardly exert dust removal effect. The field test showed that the vast majority of dust-exposed posts had the dust concentrations exceeding the occupational exposure limits (OELs), with a qualified rate as low as 31.8%. A series of rectification measures were taken for these posts. After the rectification, the dust-exposed posts demonstrated dramatically dropped C(TWA), and the qualified rate of dust concentration in the dust-exposed posts rose to 90.9%.

CONCLUSIONThe dust hazards in NSP cement production line cannot be ignored. Taking appropriate protective measures are critical for curbing dust hazards in modern cement production.
