Objective:To summarize our experience in perioperative anesthetic management for fulminant hepatic failure (FHF)patients receiving liver transplantation.Methods:The clinical anesthetic data of 48 FHF patients receiving orthotopic liver transplantations(OLT)from January 2006 to January 2007 were retrospectively analyzed,and the anesthetic management expe- rience was summarized.General anesthesia was applied;the hemodynamics was monitored during the operation and doses of adrenaline and phenylephrine were adjusted according to the monitoring results.Blood samples were obtained before operation, before anheptic,30 min after anhepatic phase,5 min before neohepatic phase,and 5 min,30 min and 60 min after neohepatic phase for blood gas and electrolyte analysis and for determination of coagulation function;the drugs were subsequently adjusted according to analysis results.Results:All the 48 patient underwent successful anesthetic management and there was no death dur- ing opearation.The average blood loss during operation was(5 219?478)ml.Mild alkalosis,hypokalemia,hyponatrium,and hy- pocalcemia were present before operations,pH,BE and HCO_3~- were obviously reduced 30 min after anhepatic phase and in- creased 60 min after neohepatic phase.Kalemia was obviously increased 30 min following anhepatic phase and began to increase 60 min following neohepatic phase.Calium concentration was decreased at the end of preanhepatic phase(P

The aim of the present research was to investigate and analyze the hunting intentions of medical students for rural grassroots in Gansu and to provide a reference for decision-making on rural health human resource . A questionnaire is the research tool which was used to investigate the views of the senior students from six medical schools , and we studied their employment willingness to rural healthcare institutions .Chi-square test and non-condi-tional logistic regression analyses were used for data analysis .A sample of 600 medical graduates was involved in this investigation.The results of this study show that more than a half (55.6%) of the students would like to work in ru-ral, but only 13.8%of which were “very willing” to work at the rural healthcare institutions .According to the out-comes of this investigation , the number of junior college students who would like to work at the grassroots was 2.3 times the number of the undergraduate students .Medical students whose monthly salary expectations were not high ,with the household registration in rural areas , and having a better understanding of the policy of rural grass-roots em-ployment were more likely to work at the rural healthcare institutions .Based on the findings of this investigation , it can be concluded that the grassroots medical career intention of medical students is not only influenced by its own fac -tors, such as education and household registration , but also the policy of the government , school employment guid-ance and social atmosphere play an important role .The above-mentioned factors should be considered by decision-making and management departments of public healthcare .The departments should introduce a reasonable recruit-ment policy and strengthen the construction of grass-roots medical technology , equipment , and infrastructure , im-prove the grass-roots of employment environment and career development opportunities and strengthen the medical students'employment guidance work to make medical students more willing to work at rural healthcare institutions .

AIMTo investigate the correlation between the gastric adaptive cytoprotection and the low concentration alcohol intake in a chronic drinking rat model and the effect of chronic ethanol exposures on the cell turnover of the gastric mucosa and its possible role in adaptive cytoprotection.

METHODSSprague-Dawley rats received the drinking water containing 6% (v/v) ethanol as their only water intake for 28 days. In the different stages of the 28 days (1st, 3rd, 7th, 14th and 28th days), the stomachs of the rats were cannulated and perfused with pure ethanol, and the severity of mucosal lesions was measured in 2 hours at the end of perfusion respectively. The cell proliferation and apoptosis in gastric mucosa of rats in different groups were analyzed by flow cytometer, immunohistochemistry and computer image analysis.

RESULTSPure ethanol caused ulcer and haemorrhagic damage in the corpus and antral mucosa of the control rats. These lesions were prevented by pretreatment of the animals with ethanol exposure in the 3 rd to 14 th days. The damage index was decreased by 80%, as compared with those in control rats. There was no significant difference in the rats exposed to the ethanol in the 1st and 28th days. Compared with control, the cell apoptosis in gastric mucosa of the rats was enhanced during they exposure to the ethanol in the 3rd to 28th days. Otherwise the cell proliferation was increased in the 3rd to 28th days, and decreased in the 28th days, respectively.

CONCLUSIONChronic adequate alcohol intake may enhance the cell turnover of gastric mucosa and lead to an adaptive cytoprotection. Long-term stimulus with the low concentration ethanol may cause the atrophy of gastric mucosa and reduce the gastric mucosal cytoprotective effect.

Objective To study the contents of puerarin in decoction with different compatibility ratios of Astragali Radix and Puerariae Lobatae Radix; To verify the rationality of compatibility ratios of Huangqi Gegen Decoction and Yu y e Decoction; To provide references for clinical medication. Methods Different compatibility ratios of Astragali Radix and Puerariae Lobatae Radix were set as 0:1, 1:1, 2:1, 3:1, 4:1, 1:2, 1:3, and 1:4. SinoChrom ODS-BP (4.6 mm × 250 mm, 5 μm) was used as the chromatographic column to detect the contents of puerarin;methanol-0.1% phosphoric acid (35:65) was used as the mobile phase with 0.5 mL/min flow rate; sample volume was 20 μL; the wavelength was 250 nm. Results The regression equation of puerarin was Y=66 449.269 1X-175 665.663 1 (r=0.999 6) in the range of 5 to 300 μg/mL, showing a good linear relationship. The repeatability, stability and recovery rate were fine as well. The contents of puerarin were (2.506 7±0.025 8)%, (2.526 7±0.071 2)%, (2.863 3± 0.086 4)%, (2.956 7±0.119 6)%, (2.835 0±0.078 7)%, (2.480 0±0.072 4)%, (2.530 0±0.064 8)%, and (2.183 3±0.128 9)% in different compatibility ratios of Astragali Radix and Puerariae Lobatae Radix with 0:1, 1:1, 2:1, 3:1, 4:1, 1:2, 1:3, and 1:4, respectively. Conclusion When the compatibility ratios of Astragali Radix and Puerariae Lobatae Radix are 2:1. 3:1, and 4:1, the contents of puerarin in decoction are the highest. This study verifies that the compatibility ratios of Astragali Radix and Puerariae Lobatae Radix in classical prescriptions are rational, which can be the optimal compatibility ratios in clinic.

OBJECTIVETo investigate the association between concentration levels of fasting serum glucose and liver cirrhosis.

METHODSA nested case-control study was carried out based on the sample cohort from the Nutrition Intervention Trials previously conducted in one country in Henan province. Using an automatic biochemical analysis system and enzyme-linked immunoassay, baseline serum samples from 310 liver cirrhosis patients and 620 healthy controls were tested for fasting glucose concentration, hepatitis B surface antigen (HBsAg), hepatitis B core antibody (anti-HBc), and hepatitis C virus antibody (anti-HCV). Baseline demographic information was collected by questionnaire. The serum glucose values were divided into quintiles and applied to a logistic regression model to estimate odds ratios (ORs) and 95% confidence intervals (95% CIs).

RESULTSThe mean fasting blood glucose level was significantly higher in cases (4.5+/-1.8 mmol/L) than in controls (4.2+/-2.1 mmol/L) (t=-2.414, P=0.016). The individuals in the highest quintile had a significantly higher risk of disease than those in the lowest quintile [OR=1.672 (1.080, 2.588)]. Moreover, increase in glucose level was accompanied by increased risk, and the relation showed statistically significant linearity (P=0.002). The statistical significance of risk remained after adjustment for potential confounders, including sex, age, HBsAg, anti-HBc, and residence running water status [OR=1.96 (1.216, 3.157), P=0.001].

CONCLUSIONElevated serum fasting glucose concentration was an independent risk factor of cirrhosis.

The aim of this study was to determine the seroprevalence and risk factors of fascioliasis in yaks, Bos grunniens, from 3 counties of Gansu Province in China. A total of 1,584 serum samples, including 974 samples from white yaks from Tianzhu, 464 from black yaks from Maqu, and 146 from black yaks from Luqu County, were collected and analyzed using ELISA to detect IgG antibodies against Fasciola hepatica. The overall F. hepatica seroprevalence was 28.7% (454/1,584), with 29.2% in white yaks (284/974) and 27.9% in black yaks (170/610). The seroprevalence of F. hepatica in yaks from Tianzhu, Luqu, and Maqu was 29.2%, 22.6%, and 29.5%, respectively. Female yaks (30.9%) had higher F. hepatica seroprevalence than male yaks (23.4%). Also, F. hepatica seroprevalence varied by different age group from 24.1% to 33.8%. Further, the seroprevalence ranged from 21.8% to 39.1% over different seasons. Interestingly, the season and age of yaks were associated with F. hepatica infection in yaks in the investigated areas. These findings provided a basis for further studies on this disease in yaks from 3 counties of Gansu Province in northwestern China, which may ultimately support the development of effective control strategies of fascioliasis in these areas.

OBJECTIVETo observe the effect of Tongsaimai (TSM) tablets in treating foot trauma of diabetic foot (DF) model rats, and discuss its potential mechanism.

METHODMale SD rats were selected to duplicate the diabetic foot ulcer model and randomly divided into the blank control group, the model group, the metformin treatment group, and TSM 12.44, 6.22, 3.11 g x kg(-1) groups (n = 10). The healing of ulcer wounds were observed on day 1, 4, 8, 13 and 18. After 18 days, a histopathologic examination was conducted for ulcer tissues. The contents of superoxide dismutase (SOD) and malondialdehyde (MDA) were detected by hydroxylamine and TBA methods. The content of interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha) were determined with the radioimmunoassay. The immunohistochemical method was used to observe the expression of vascular endothelial growth factor (VEGF) in ulcer tissues and the number of capillary vessels.

RESULTTSM could alleviate the pathological changes of diabetic foot rats, accelerate the ulcer healing on 4, 8, 13, 18 d, reduce MDA, IL-6, TNF-alpha, VEGF content in rat serum at 18 d (after the rehabilitation period), and enhance the SOD content. Specifically, the TSM 12.44 g x kg(-1) group showed significant differences compared with the model group (P < 0.05, P < 0.01). At 18 d after the treatment (the late rehabilitation period), the VEGF expression of TSM 12.44, 6.22 g x kg(-1) groups and the number of blood capillaries of the TSM 12.44 g x kg(-1) group were significantly lower than that of the model group (P < 0.05, P < 0.01).

CONCLUSIONTSM could promote the foot wound healing of DF model rats, reduce MDA, IL-6 and TNF-alpha levels in serum, increase the SOD content and decrease the VEGF expression and the number of blood capillaries in the late rehabilitation period. Its action mechanism may be related to the inhibition of oxidative stress injury and the inflammatory cell infiltration.
