The writing of vocational college thesis is the maln way to test whether the students are able to analyze and solve practical problems with the professional knowledge and skills they've learnt, as well as improve the capability of production and practice. This paper analyzes the present situation of the thesis written by higher vocational college students majoring in pharmaceutical sci-ences, and figures out the four kinds of evaluation standards about graduation thesis for students in various pharmaceutical fields with different problems. The four kinds of evaluation standards includes key point analysis on Standard Operation Procedure (SOP), planning strategy for pharmaceutical mar-keting, investigation of rational use of drugs in hospitals and subject research. The author puts forward the solving method for the problem, and formulate the evaluation requirements.

Objective:To investigate the effect of poly (lactic acid)(PLA)electrospun membranes loaded with cisplatin and chloroquine on the oral squamous cell carcinoma CAL-27 cells,and to explore the method to prevent the recurrence of oral cancer.Methods: The DDP/PLA membranes, CQ/DDP/CQ/PLA membranes and CQ/DDP/PLA membranes were prepared by electrospinning.Then the micro morphology of three kinds of membranes were observed by scanning electron microscope (SEM);the degradation rate of PLA membrane was measuredby UV spectrophotometric.The LC3-Ⅱ expression level in CAL-27 cells was detected by laser scanning confocal microscope.The survival rate of CAL-27 cells was detected by MTT method.Results:The SEM results showed that the nanofibers of DDP/PLA,CQ/DDP/PLA and CQ/DDP/CQ/PLA membranes were continuous and smooth with uniform diameters.The degrated time of membranes was about 21 d.The MTT result showed that compared with control group,at first,the effects of cell killing of DDP/PLA membranes,CQ/DDP/CQ/PLA membranes and CQ/DDP/PLA membranes were not obvious;as the extension of time,the survival rates of CAL-27 cells in DDP/PLA membranes group,CQ/DDP/CQ/PLA membranes group and CQ/DDP/PLA membranes group were decreased (P <0.05).The immunofluorescence results showed that the fluorescence intensity of LC3-Ⅱ in CQ/DDP/CQ/PLA membranes group and CQ/DDP/PLA membranes group were lower than that in DDP/PLA membranes group.Conclusion:CQ/DDP/PLA membranes with sustained-release effect can increase the sensitivity of CAL-27 cells to DDP and enchance the killer effect of DDP on the CAL-27 cells.

AIM: To study the expression of mic2/CD99 protein and their correlation with Eber-1/LMP-1 in Hodgkin and Reed-Sternberg cells of classical Hodgkin's lymphoma. METHODS: Immunohistochemical staining, in situ hybrization and tissue microarry technique were used to detect the expressions of mic2/CD99 and Eber-1/LMP-1 of H/RS cells in 43 cases of cHL and 16 cases of NHL. RESULTS: The positive rate of CD99 protein expression in 43 cases of cHL was 2.3% (1/43) , mic2 was 55.8% (24/43), LMP1 was 58.1% (25/43) and Eber-1 was 53.5% (23/43). The expressions of CD99 and mic2 in the NHL group were higher than those in cHL group (P0.05). There was a negative correlation between the expression of CD99 protein and LMP1 in H/RS cells (P0.05). There was a significant correlation between the high expression of LMP1 and a low expression of CD99 in the young patients (P0.05). CONCLUSION: There is a negative correlation between the expression of LMP1 and CD99 in Hodgkin and Reed-Sternberg cells of classical Hodgkin's lymphoma.

Objective To investigate tissue distribution of Hylotelephin in Beagle dogs and excretion of Hylotelephin in rats. Methods A high performance liquid chromatography (HPLC) with UV detection was developed to study the concentrations of Hylotelephin in biological samples, taking anthracene as an internal standard, Benzoyl chloride as the pre-column derivatization of Hylotelephin and methanol-water as the mobile phase. Results After a single intravenous dose of 10.6 mg/kg Hylotelephin in beagle dogs, parent drug was widely distributed to virtually all tissues in 5 min and the concentration of Hylotelephin in most tissues at 90 min were lower than those at 5 min obviously. Hylotelephin was mainly distributed in kidney, liver and spleen, secondly in heart, lung and intestine. The parent drug concentration in kidney, liver and spleen was similar to that in blood at the same time point. After a single intravenous dose of 36 mg/kg Hylotelephin in rats, the excretion of the parent drug in urine, feces and bile amounted to 88.45%, 0.61% and 1.08% of the dose, respectively. The parent drug excretion amounted to 67% of the dose in 3 h. Conclusion Hylotelephin was distributed and eliminated in Beagle dogs rapidly. It was mostly distributed in kidney, liver, spleen and plasma. The parent drug excretion was 88% via urine.

This article was aimed to compare the antioxidant activities of Green tea and four tree-type non-Camellia teas. The antioxidant activities of the water extract of Green tea, Eagle tea, Large-leaved Kuding tea, Shiya tea and Qingqianliu tea were evaluated with four different in vitro assays including 1,1-diphenyl-2-picryl-hydrazyl (DPPH), ferric-reducing antioxidant power (FRAP), ferrous ion-chelating (FIC) and β-carotene-linoleate bleaching assay. In addition, the polyphenol contents of different teas were estimated by the Folin-Ciocalteu assay. The results showed that Shiya tea had strong antioxidant activity; its FIC and FRAP abilities are better compared with Green tea. The Eagle tea and Large-leaved Kuding tea have better antioxidant activity. The FRAP activity of Large-leaved Kuding tea was better than green tea. The DPPH of Eagle tea and Large-leaved Kuding tea were slightly lower than Green tea, but higher than the butylated hydroxytoluene (BHT). The antioxidant ability of Qingqianliu tea was the lowest. It was concluded that Shiya tea, Eagle tea, Large-leaved Kuding tea had relatively high development value which re-quires in-depth research and promotion.

Aim To evaluate the hypolipidemic effect of total phenylpropanoid glycoside extracted from Ligustrum robustum(Roxb.)Blume(CNTG)and its mecha-nisms.Methods The 60 hamsters were randomly divided into six groups,namely the control group,the model group,the positive control group(fenofibrate,150 mg·kg-1),the high(1 200 mg·kg-1),medium(600 mg·kg-1)and low(300 mg·kg-1)doses of CNTG groups.Only the control group was given control diet and other groups received high-fat diet.The changes of serum lipid were measured and analyzed in 1st week to ensure the successful establishment of the model.The drugs were administered daily for four weeks and the concentrations of lipids were determined in the 2nd week,3rd week and 4th week respectively.Quantitative real-time PCR and Western blot were used to assay the mRNA and protein expression of related signaling enzymes and proteins.Results Compared with the model group,the concentrations of serum TG,TC,LDL-C(P<0.05,P<0.01)and hepatic TG,TC(P<0.01)were effectively reduced in hamsters in CNTG-treated groups.Mechanism research found that CNTG increased the levels of phospho-AMPKα,LKB1 and phospho-LKB1 in liver(P<0.05).Conclusion CNTG prevents hyperlipidemia via activation of hepatic LKB1-AMPK pathway.

Objective: To observe the effects of acupuncture at Yuan-Primordial and Luo-Connecting points by host-guest combination plus Tuina (Chinese therapeutic massage) on the third lumbar transverse process syndrome. Methods: A total of 88 patients with the third lumbar transverse process syndrome were selected and divided into an observation group and a control group according to the random number table method, with 44 cases in each group. The control group was treated with Tuina, and the observation group was treated with additional acupuncture at Yuan-Primordial and Luo-Connecting points by host-guest combination. The clinical efficacy of the two groups was compared after treatment. The changes in the scores of physical signs, Roland-Morris disability questionnaire (RMDQ), Oswestry disability index (ODI), Quebec back pain disability scale (QBPDS), and pain factors [including serum prostaglandin (PG) E2, neuropeptide Y (NPY), and matrix metalloproteinase-3 (MMP-3)] were observed. Results: After treatment, the total effective rate in the observation group was 93.2％, higher than 75.0％ in the control group; the difference between the two groups was statistically significant (P<0.05). Compared with those before treatment, the scores of physical signs and each low back pain scale, and the levels of serum pain factors in the two groups were decreased (P<0.05), and those in the observation group were lower than those in the control group (P<0.05). Conclusion: Acupuncture at Yuan-Primordial and Luo-Connecting points by host-guest combination plus Tuina is effective in the treatment of the third lumbar transverse process syndrome; it can improve the patient's physical signs, relieve low back pain, and reduce the levels of serum pain factors.
