Purpose:To evaluate the protection of astragalus injection for Doxorubicin (adriamycin)-associated cardiotoxicity. Methods:58 patients were randomized into two groups for this clinical trial. 30 patients were in the test group ,and 28 in control group. Patients in the test group received astragalus injection in 5% glucose solution once every day for two weeks starting three days before adriamycin-based chemotherapy. 28 patients in the control group began to receive oral vitamin E 100 mg twice a day and coenzyme Q10 20 mg three times a day for two weeks. Chemotherapy is the same as that in the test group. Electrocardiogram (ECG) and echocardiogram were employed to evaluate the cardiac function. Results:There was a substantial difference in ejection fracton between the two groups,but the difference was not statistically significant. Statistically significant differences were observed in the two groups with regard to all other parameters,including abnormal changes in ECG and LVIDD、LVISD、A/E、FS. Conclusions:Astragalus injection is a good drug which can prevent the occurrence of acute cardiotoxicity associated with adriamycin. It can also reduce the occurrence of chronic cardiotoxicity.

Objective To investigate the effect of preoperative prophylactic parenteral nutrition on prognosis of advanced gastric cancer.Methods A total of 159 patients with advanced gastric cancer in our hospital were collected,and randomly divided into experimental group and control group.80 cases in experimental group were treated with prophylactic parenteral nutrition,and 79 cases in control group were treated with traditional nutrition.The partial indexes of liver function,complications and mortality rate were compared between the two groups before and after surgery.Results The levels of aspartate aminotransferase (AST),alanine aminotransferase (ALT),total bilirubin (TBIL) and direct bilirubin (DBIL) were much lower in experimental group than in control group at 8 days after surgery (t=6.542,6.460,5.634,5.275,all P＜0.001).The levels of ALB and PAB were much higher in experimental group than in control group at 2 and 8 days after surgery (t=12.580,12.471,6.757,12.821,all P＜0.001).The incidence of complications and mortality rate were much lower in experimental group than in control group (x2 =23.409,4.818,P＜0.001 or 0.05).Conclusions Preoperative prophylactic parenteral nutrition can speed up the recovery of liver function and reduce the complications and mortality rate after surgery in patients with advanced gastric cancer.

Objective To evaluate the effects of ozoned water on the synovial inflammation in rabbits with knee osteoarthritis.Methods Thirty-two rabbits were randomly and evenly divided into four groups by random number method.All the rabbits were made into osteoarthritis models except those in groups A and D.After the osteoarthritis models were made successfully,rabbits in groups C and D received intra-articular injection of ozoned water of 20 μg/ml (2 ml)once a week for three weeks,and the other two groups did not.The morphology of synovium was observed and the expres-sion levels of IL-6 and TNF-α in the synovium were compared among the four groups.Results In group A,there was no hyperemia,edema or cell hyperplasia in the synovium,and the synovium re-mained normol tissue structure.In group B,the synovial structure was damaged,with serious cell hyperplasia,masses of inflammatory cells invading,vascular proliferation and hyperemia,and signifi-cantly increased synovium thickness compared with the normal.In group C,synovial hyperemia and edema were improved,the inflammatory cells reduced,and the synovium thickness was thinner than that in group B.And the group D had no synovitis phenomenon.Compared with group A,the expres-sions of IL-6 and TNF-αwere slightly higher in group D,and they were significantly increased (P <0.05)in the other two groups.Compared with group B,the IL-6 and TNF-α contents of synovium were reduced (P < 0.05)in group C.Conclusion Injecting 2 ml ozoned water of 20 μg/ml into artic-ular cavity can significantly improve synovial inflammation and reduce the expression of IL-6 and TNF-αin the synovium,which does no damage normal synovium.

Strong inhibition of Bacillus subtilis strain NJ-18 on mycelia growth of Alternaria solani was observed in the antagonistic tests by cylinder plate methods, and the inhibition width was 21.5 mm. Observation under microscope found that the supernatant of fermentation from NJ-18 could make the pathogen hyphae cells malformed and swelled, and consequently the growth of the pathogen was inhibited. Determining of the colonization in potato plants by the signed rifampicin-resistance in NJ-18 showed that it could colonize well in the plants, the colonization quantity of NJ-18 in the root and stem of the potato detected 30 days after fermentation irrigation was 103 CFU/g plant’s fresh weight. In pot experiment, we inoculated the tomato plants with the spore suspensions of Alternaria solani after spraying the fermentation of NJ-18, the results were investigated in 14 days and the efficacy in controlling the disease was 72.9%, which was significantly higher than 45.7%, the efficacy resulted from spray treatment of 2000 fold dilution of 50% iprodione wetable powder.

Objective To explore the effects of lamotrigine on the cognitive function and the quality of life in epilepsy patients.Methods This was a prospective study and 91 newly diagnosed epilepsy patients were enrolled.The neuropsychological tests score and the quality of life in epilepsy inventory(QOLIE-31) were obtained before and after the treatment with lamotrigine.A battery of neuropsychological tests comprised the auditory verbal learning test(AVLT), the logical memory test(LMT), the digital symbol test(DST), the stroop color word test(SCWT), the trail making test(TMT), the verbal fluency test(VFT), the WAIS block design test(WBDT), the WAIS digital span test(WDST)and the Boston naming test(BNT). Results The repeated assessments in the patients taking lamotrigine were associated with significant improvements in many domains.The greatest changes were observed in the immediate and delayed recall of AVLT, DST, the time consuming of SCWT card C and TMT test A and B, the immediate and delayed recall of LMT, VFT, WBDT and BNT.For the quality of life, significant improvements were recorded in the fields of the seizure worry(38.81?16.06 vs 45.68?15.18), the overall quality of life(59.12?13.50 vs 64.99?13.33), the social function(64.59?25.14 vs 69.41?22.70)and the self-health evaluation (71.18?13.73 vs 76.75?11.30).Conclusion Improvements of the cognitive function and the quality of life can be observed in the initial period of medication with lamotrigine in epilepsy patients.

Background and purpose: As one of the important epigenetic phenomena, DNA methylation plays an important regulatory function for the expression of genes. Study shows that abnormal changes of DNA methy-lation patterns of normal tumor cell genome leads to dysfunction of cancer related gene, and this may be associated with tumor occurrence and development. The study investigated the promoter methylation and expression of caveolin-1 (CAV-1) gene in esophageal squamous cell carcinoma (ESCC), and to elucidate its role in ESCC. Methods:We used MSP approach, RT-PCR, and immunohistochemistry method respectively to examine the methylation status of the 5’CpG island of CAV-1 gene and its expression at mRNA and protein levels in tumors and corresponding normal tissues. Results: CAV-1 mRNA expression in tumor tissues (0.86±0.56) was signiifcantly higher than that in corresponding normal tissues (0.40±0.36, P<0.05). The mRNA expression of CAV-1 was correlated with status of lymphatic metastasis and TNM stage of ESCC patients (P<0.05). The protein expression of CAV-1 in tumor specimens (66.7%, 34/51) was signiifcantly higher than that in corresponding normal tissues (15.7%, 8/51, P<0.01). The protein expression of CAV-1 was signiifcantly associated with lymphatic metastasis of ESCC (P<0.05), however, it was not associated with differen-tiation and TNM stage (P>0.05). The promoter methylation frequency of CAV-1 in tumor specimens was 2.0%(1/51), and the methylation phenomenon has not been found in corresponding normal tissues. The promoter methylation fre-quency of CAV-1 in tumor specimens showed no signiifcant difference compared with the corresponding normal tissues (P>0.05). Conclusion:The mRNA and protein expression of CAV-1 in tumor specimens was signiifcantly higher than that in corresponding normal tissues. Aberrant high expression of CAV-1 has played a certain role in promoting tumori-genesis and lymph node metastasis. The expression both in ESCC and corresponding normal tissues has no correlation with the promoter methylation status.

Objective To summarize our experience in the prevention and treatment of accessory hepatic duct injury during operation on biliary tract.Methods The clinical data of 26 cases with accessory hepatic duct were retrospectively reviewed.Results Of 26 cases,the accessory hepatic duct were type I in 38.5%(10/26),and no complications including bile leakage,biliary infection and obstructive jaundice developed after division and ligation of the accessory hepatic duct;26.9%(7/26) were type II,among which,the accessory hepatic duct were injured in 3 cases,but no case developecl complications after relevant treatment;23.0%(6/26) were type III,among which,injury of accessory bile duct occurred in 2 cases.Of them,1 case developed bile leakage and was cured by reoperation.7.7%(2/26) were type IV and 3.9%(1/26) was type V.The cases of type IV and V were not damaged.Conclusions To prevent injury of accessory hepatic duct,pre-and intra-operation identification of the condition is very important,and especially by intraoperative cholangiography.Different types of accessory hepatic duct injury should be treated by different approaches. Accessory hepatic duct of type I might be cut and ligated.Type II accessory bile duct which(enters) the cystic duct and should be protected,but,if damaged,different methods of treatment are used,(depending) on the caliber of accessory hepatic duct.Type III and IV also should be protected,but,when damaged,the accessory hepatic duct should be repaired or performed an internal draining.

Purpose To investigate the expression of Cav-1 in gastric cancer ( GC) cell lines and GC samples, and to analyze the pos-sible effect of gene methylation in expression of Cav-1. Methods Methylation specific PCR ( MSP) method was applied to examine the CpG methylation of the Cav-1 promoter in GC cell lines (AGS, MKN45, BGC-823) and 104 samples of GC and corresponding ad-jacent tissues. RT-PCR method was applied to examine the mRNA expression in GC cell lines. IHC were applied to examine the pro-tein expression of Cav-1 in the GC tissues. Results The expression level of Cav-1 mRNA was obviously increased after treated with 5-aza-2’-deoxycytidine (5-Aza-Dc, a demethylation agent) in AGS cell line. We detected the positive expression of Cav-1 gene in MKN45 and BGC-823 cell lines before and after treated with 5-Aza-Dc. The level of Cav-1 mRNA expression was no any change in AGS, MKN45 and BGC-823 cell lines treated with trichostatin A (TSA). MSP results showed that it can be amplified methylated bands in AGS cell line, and the methylated bands disappeared after treated with 5-Aza-Dc. MKN45 and BGC-823 cell lines were no any methylated bands amplified before and after treatment. The methylation frequency of Cav-1 gene was 29. 8% (31/104), which was significantly higher than that in adjacent tissues (P=0. 000). Furthermore, Cav-1 gene hypermethylation status was correlated with lymph node metastasis and family history of upper gastrointestinal cancers ( UGIC) , but not with pathological grade and clinical stage (P>0. 05). The positive frequency of Cav-1 expression was 51. 9%(54/104) in GC, which was significantly lower than that in adja-cent tissues (P=0. 000). The expression of Cav-1 was correlated with the frequency of gene methylation in GC tissues (P=0. 000). Conclusion The expression of Cav-1 was reduced in GC tissues and the gene hyermethylation may be one of the mechanisms causing Cav-1 gene silencing.

In this paper, the varying pattern of the amount of rhizospheric microorganisms, including bacteria, actinomycetes and fungus, was observed during the cultivation of Paris polyphylla var. yunnanensis. And the correlations between number of rhizospheric microorganisms and the quality of P. polyphylla var. yunnanensis were also studied. The results showed that the rhizospheric microorganism source of P. polyphylla var. yunnanensis was rich. The distribution of rhizospheric microorganisms (soil bacteria, fungus, actinomycetes, potassium-solubilizing bacteria, inorganic phosphorus-solubilizing bacteria, organic phosphorus-solubilizing bacteria) collected from different origin places existed significant difference (P < 0.05). The varying pattern for the amount of rhizospheric microorganisms was showed as following: the amount of bacteria > the amount of actinomycetes > the amount of fungus. The medicinal quality of P. polyphylla var. yunnanensis was influenced by their habits, and the increase of cultivation years caused the obvious decrease of the quality of P. polyphylla var. yunnanensis. Therefore, the increase of cultivation years will cause the variation of the soil micro-ecology flora, and decrease the nutrient absorption and the utilization of P. polyphylla var. yunnanensis, which will make the decrease of the medical quality of P. polyphylla var. yunnanensis.
