Strains from the cellulose-containing environment were collected. Primary screening (by filter-paper Hutchison solid culture medium and sodium carboxymethylcellulose solid culture medium) and reelection(by filter-paper inorganic salt culture medium and sodium carboxymethylcellulose Congo red culture medium) indicated that five strains obtained were best suited for high performance cellulose degradation. Determination of sodium carboxymethylcellulose activity(CMCA) and filter paper activity(FPA) was accomplished for each of the five. The strongest of the five in CMCA and FPA was applied to the production of cellulose bioethanol by separate hydrolysis and fermentation(SHF) and simultaneous saccharification and fermentation(SSF) respectively.

To improve the management level of patients' information of schistosomiasis control stations in Nanchang City,the B/S three-layer architecture and ASP+SQL technology were applied to formulate the WEB-based management system of chronic schistosomiasis patients' information,so as to achieve the information sharing of chronic schistosomiasis among schistosomiasis control stations.

Backgroud EDTA is an important calcium chelator,commonly used as an ophthalmic additive,its role in promoting corneal penetration of drug may facilitate transepithelial corneal collagen crosslinking.However,there were few reports about the penetration of riboflavin to corneal stroma enhanced by EDTA both home and abroad.Objective To determine the concentrations of riboflavin in corneal intrastromal under different interventions using high-performance liquid chromatography (HPLC).To ensure the efficacy and safety of 0.5％ EDTA in riboflavin penetrating to corneal stroma by the transepithelial procedures.Methods Fifteen New Zealand white rabbits were randomized into three groups,corneal epithelium of 5 rabbits were debrided,corneal epithelium of another 5 rabbits were left in situ and 0.5％ EDTA-Na2 was topically applied for 1 hour,and the corneal epithelium of last 5 rabbits were just left in situ,after those procedures 0.1％ riboflavin + 20％ dextran was applied topically to the corneas for 30 minutes(1 drop every 3 minutes).Then,the epithelium in the corneas of EDTA and epi-situ group were carefully removed before all the corneas were punched with an 8.5 mm diameter blade and homogenized subsequently.Ultimately,the riboflavin concentrations were determined by HPLC.Results After treated with riboflavin for 30minutes,the mean concentration of riboflavin in the epi-removed group was (23.54± 1.61)μg/g tissue,the EDTA group was (2.04 ±0.25)μg/g tissue and the epi-situ group was (1.44 ±0.06)μg/g tissue,showing significant difference among them (F =1792.839,P =0.000).There were statistically significant differences between any two groups (t =41.780,7.484,43.408,all at P ＜ 0.05).However,the riboflavin concentration of other two groups were failed to meet the theoretical value 15 μg/g tissue,excepted for epi-removed group.Conclusions The diffusion of riboflavin to the corneal stroma can be fully enhanced by removing the epithelium preoperatively,penetration enhancer EDTA can effectively promote the penetration of riboflavin to the cornea,but it still can not replace the role of removing epithelium on the penetration of riboflavin to the cornea.

Objective To investigate the effect of nursing interventions on the quality of life after radiotherapy in nasopharyngeal cancer. Methods 56 patients with nasopharyngeal cancer who received radiotherapy were randomly divided into control group and intervention group. All the patients were given conventional nursing interventions, and those in the intervention group were given accurate evaluation, enhanced psychological guide, reasonable dietary guide, and special nursing for preventing and treating complications. All the patients were evaluated by using quality of life questionnaire core 30 items(QOL-C30). Results The scores of the dimensions of somatic function,psychological function, social function and material life after interventions in the intervention group were significantly higher than those in the control group (P＜0.05 ). Conclusion Nursing interventions can improve the quality of life, and the therapy can be completed smoothly.

Objective To study the effect of tetracaine jelly on hemodynamics during extubation period in general anesthesia.Methods One hundred patients who performed tracheal cannula and general anesthesia were divided into control group (50 patients) and experiment group (50 patients) by random digits table method.Control group:sterile paraffin oil was applied to the endotracheal tube.Experiment group:tetracaine jelly was applied to the endotracheal tube.The systolic blood pressure (SBP),diastolic blood pressure (DBP) and heart rate(HR) were measured before the anesthesia induction(T1),5 min after stopping infusion drugs (T2),1 min after tracheal extubation (T3),3 min after tracheal extubation (T4) and 5 min after tracheal extubation (T5) were observed.The resistant effect after waking and the number of sore throat,hoarseness were recorded.Results The level of SBP,DBP,HR at T1 and T2 had no significant difference between two groups (P ＞ 0.05).The level of SBP,DBP,HR at T3-T5 in experiment group were significantly lower than those in control group [SBP:(122.3 ± 11.3),(120.0 ± 9.8),(112.0 ± 6.3) mmHg (1 mmHg =0.133 kPa) vs.(158.3 ± 15.0),(142.5 ± 13.5),(133.0± 14.5) mmHg;DBP:(75.0 ± 13.5),(75.8 ± 10.5),(58.3 ±4.2) mmHg vs.(111.0 ± 20.3),(106.5 ± 12.8),(63.8 ± 15.8) mmHg;HR:(81.9 ± 13.7),(83.6 ± 13.4),(60.7 ± 3.5) times/min vs.(113.5 ± 19.4),(117.5 ± 21.7),(71.8 ± 14.6) times/min](P ＜ 0.05).The total effective rate of tolerance in experiment group was higher than that in control group [96％(48/50) vs.56％(28/50)],the rate of sore throat and hoarseness were lower than those in control group [6％ (3/50) vs.48％ (24/50),4％ (2/50) vs.36％ (18/50)],there were significant differences (P ＜ 0.05).Conclusion Tetracaine jelly can reduce the cardiovascular response of tracheal extubation,enhance the tolerance of tracheal tube and decrease the morbidity of sore throat and hoarseness.

OBJECTIVE:To study the safety of percutaneous administration of Hongzhi gutong cataplasm. METHODS:Rab-bits were taken for single dose in complete skin irritation test(n=4),single dose in damaged skin irritation test(n=4)and multi-ple doses in complete skin irritation test(n=4). The left and right sides of the skin respectively paste 3 cm×3 cm blank matrix and Hongzhi gutong cataplasm for 24 h(calculated by crude drug of 0.14 g). After removing tape 1,24,48,72 h,the erythema and edema in hair removal site of rabbits in the former 2 tests were observed;after 24 h of administration,the rabbits in the last group were administrated again after exposing the administration area for 1 h,repeated 3 times,the erythema and edema in hair removal site after removing tape the first,second time and 1,24,48,72 h in the third time were respectively observed. RESULTS:In the 3 experiments,the scores of erythema and edema of all rabbits were 0,and skin irritation was evaluated as no irritation. CONCLU-SIONS:Hongzhi gutong cataplasm has no skin irritation in rabbits.
