OBJECTIVE:To discuss the application of Prescription Automatic Screening System (PASS) in the examination of clinical medical orders. METHODS: The level and type of caution and the modification rate of medical orders in our hospital between April 2005 and April 2006 were analysed statistically, and the conformity between PASS cautions of medical orders and clinical medications was evaluated. RESULTS: A total of 10 982 160 medical orders were monitored by PASS, of which, 11 146 were with black cautions and in which 2 861(25.67%) were modified, 51 504 were with red cautions and in which 10 357 (20.0%) were modified, 339 449 were with yellow ones and in which 66 022 (19.45%) were modified. In PASS monitor process, inconformity between feasible clinical medical orders and cautions of PASS was noted in a few cases. CONCLUSION: The examination of medical orders using PASS is convenient and rapid and the PASS can help improve clinical rational drug use level, however, its function of remains to be updated and optimized.

Objective To evaluate the prognosis and influencing factors of unprotected left main coronary artery lesion intervention with drug-eluting stents.Methods Forty-five patients with unprotected left main coronary artery disease were treated with percutaneous coronary intervention (PCI).According to whether the lesions involving the distal left main bifurcation,the patients were divided into two 2 groups:nonbifurcation lesion group (26 cases) with opening or body disease,bifurcation lesion group (19 cases) with involving the distal left main or anterior descending artery,circumflex openings.Fifteen patients were guided by intravascular ultrasound (IVUS) during PCI,and 13 patients were reviewed by coronary angiography at (9.5 ±6.3) months after PCI.Results All the 45 patients were successful.There were 42 patients successfully finished the follow-up study for the average of 8-48 (19.9 ± 10.2) months,non-bifurcation lesion group was 24 cases,bifurcation lesion group was 18 cases.The incidence of recurrent angina pectoris during the follow-up period in bifurcation lesion group was significantly higher than that in non-bifurcation lesion group [6/18 vs.12.5％ (3/24)],there was statistical difference (P ＜ 0.05),but there was no statistical difference in the incidence of major adverse cardiac events (MACE) between 2 groups [3/18 vs.12.5％ (3/24),P ＞ 0.05].Single-variable analysis results showed that MACE in IVUS guided during PCI was less than that in non-IVUS guided during PCI [1/15 vs.18.5％(5/27)],there was statistical difference (P ＜0.05).In 13 patients who reviewed by coronary angiography,4 patients were found in-stents restenosis,all in bifurcation lesion group,the rate of restenosis in double stents was 3/6,in simple stents was 1/4.Conclusions PCI with drug-eluting stents is safe and feasible for the treatment of selective left main coronary artery lesion,it could bring the better short and long-term outcomes.IVUS guided PCI could significantly reduce MACE.

Objective:To study B cells proliferation and activation induced by tumor derived-autophagosomes ( TDA). Methods:Splenocytes of mice were incubated with 10μg/ml TDAs in vitro ( with the 10μg/ml whole cell lysate as the control).At the 3rd day,the expression of MHCⅠ,Ⅱand co-stimulate molecules including CD86,CD40 were detected by flow cytometry,and B cells proliferation was detected at the 5th day.B cells were selected from spleen of mice using anti-CD43 dynabeads,and incubated with 10μg/ml TDA in vitro ( with the same concentrated whole tumor cell lysate as the control).At the 7th day,IgM in the supernatant were tested by ELISA.Results:When compared with whole cell lysate stimulated B cells,TDA efficently stimulated B cells division in vitro ( TDA group:28.6%, Whole cell lysate group:4.4%) , and significantly up-regulated the expression of MHC class Ⅰ,Ⅱ and co-stimulatory molecules (CD86 and CD40) on B cells,and enhanced the levels of total IgM secretion in vitro.Conclusion:Tumor-derived autophagosomes ( TDA) ,as a vacuole antigen vector, could stimulate B cells proliferation, activation, and increased IgM secretion in vitro.

ObjectiveTo investigate the clinical efficacy of focused ultrasound for treating non-neoplastic epithelial disorders of vulvar.

Objective To realize job satisfaction of doctors from the secondary hospital and its influencing factors and put forward countermeasures for doctor job satisfaction.Methods 2066 doctors from the secondary hospital were investigated by self-made scale,and analyzed by analysis of variance,non-conditional logistic regression analysis and other methods.Results The average score of total job satisfaction of doctors was (3.44±0.95),in which about 57.6% of doctors expressed satisfaction with the current work.The scale of job itself satisfaction had the hisheet score,that was (3.91±0.79),while the scale of job retum satisfaction had the lowest score,that was (2.85±1.16).Leadership behavior played the most decisive role in doctors job satisfaction(sβ=0.7,P<0.01).Condusion The total job satisfaction of secondary hospital doctors is just above the average and doctors are most dissatisfied with the work concentrated in the areas of return and the practice environment.

AIM:To evaluate the clinical effects of femto-LASIK using new Ziemer LDV Z6 femtosecond laser machine (Z6).
METHODS: Two - hundred cases ( 400 eyes ) was randomly separated into two groups: Group A included 200 eyes which corneal flaps were made by Z6, and Group B included rest of 200 eyes which corneal flaps were examined by a traditional Ziemer LDV CrystalLine femtosecond laser machine (CrystalLine). Visual acuity, slit lamp, refraction, Sim-K average, intraocular pressure (IOP), non-invasive tear break-up time (NIAvg-BUT), operation difficulty and complications were compared between two groups preoperatively and postoperatively.RESULTS:There was no significant differences between two groups in visual acuity, refraction, Sim-K average, IOP and NIAvg - BUT either preoperatively or 6mo postoperatively (P>0. 05). Although there were significant differences in operation difficulty and complications were found between two groups ( P< 0. 05 ), there was no serious complication in any group. Furthermore, a clear demarcation line could be observed in the cornea of Group A postoperatively.
CONCLUSION:More careful and strict requirements are needed when using the new Z6 femtosecond laser for corneal flaps.

OBJECTIVE:To observe therapeutic efficacy and safety of applying dexamethasone+docetaxel+cisplatin+fluoroura-cil(DCF)regimen induction chemotherapy before Ⅲ-Ⅳ stage oral squamous cell carcinoma resection. METHODS:A total of 120 patients with Ⅲ-Ⅳ stage oral squamous cell carcinoma were randomly divided into control group(60 cases)and observation group (60 cases). Both groups were given oral cancer resection,control group received radiotherapy 4-6 weeks after surgery,observation group was additionally given Dexamethasone acetate tablets 0.75 mg orally once a day,d1-7+Docetaxel injection 80 mg/m2 added in-to 0.9% Sodium chloride solution 250 mL intravenously for 2 h,d2+Cisplatin injection 80 mg/m2 added into 0.9% Sodium chloride solution 250 mL intravenously for 1 h,d2+Fluorouracil injection 750 mg/m2 added into 0.9% Sodium chloride solution 500 mL in-travenously,d2-5. Treatment course of 2 groups lasted for 7 d. Clinical efficacies of 2 groups were observed as well as EORTC QLQ-C30 score before and after treatment,recurrence rate 12,24,36 months and the occurrence of ADR. RESULTS:The short-term total response rate of observation group was significantly higher than that of control group;12,24,36 months fol-low-up recurrence rate of observation group were significant lower than those of control group;the incidence ofⅠ-Ⅱ degree nausea and vomiting,leucopenia in observation group were significantly higher than control group,with statistical significance (P<0.05);there was no statistical significance in the incidence of Ⅲ-Ⅳ degree nausea and vomiting,leucopenia andⅠ-Ⅱ,Ⅲ-Ⅳ de-gree diarrhea between 2 groups (P>0.05). Before treatment,there was no statistical significance in EORTC QLQ-C30 score be-tween 2 groups(P>0.05). After treatment,EORTC QLQ-C30 score of 2 groups were significantly lower than before,with statisti-cal significance (P<0.05),but there was no statistical significance between 2 groups (P>0.05). CONCLUSIONS:The applying of DCF regimen induction chemotherapy can improve short-term efficacy before Ⅲ-Ⅳ stage oral squamous cell carcinoma resec-tion,reduce reoccurrence risk but induce high incidence ofⅠ-Ⅱ degree nausea and vomiting,leucopenia.

Objective To observe the effect of aminoguanidine by intraperitoneal injection on apoptosis of chondrocyte with osteoarthritis.Methods Totally 32 rabbits were divided into 3 groups at random.Both the experiment and the model groups were fixed by plaster cast in the right hind straighten limb,while the control group received no treatment.The experiment groups were injected with aminoguanidine in abdominal cavity,100mg/(kg?d),and the control groups were injected the same voluminal normal saline in abdominal cavity.At the 4th week,we killed 4 rabbits from the normal group,and 6 from the control group and the experiment group,respectively.At the 8th week,we put the rest to death.We drew the materials from each sample for pathological observation on the whole and under the light microscope by HE and immunohistochemical staining,and counted apoptosis cells by TUNEL for statistical analysis.Results Compared with the control group,the experiment group was more similar to the normal group in general observation and optical microscope observation by HE staining.Both iNOS positive expression cell by immunohistochemical staining and apoptosis cell calculation by TUNEL of the experiment group were fewer than those of the control group(P

5.16 log of K562, U937, HIMeg and HL60 cells, respectively, but spare 23.37 ? 25.66% of normal CFU-GM (0.63 log killing). When HL60 cells mixed with normal mononucleated bone marrow cells in 1:9 ratio were studied, the killing of HL60 colonies was more than 4.29 log. The result suggested that photocarcinorin plus light could eliminate leukemic progenitors, and might be used in clinical ABMT. Several factors that might affect the photosensitization effect on cells were discussed.

Objective To investigate the protective effect of the ethanol extract of vacciniuin bracteatum thumb leaf on acute liver injury induced by CC14 in mice. Methods Sixty mice were allocated into 6 groups randomly, respectively as the normal control group,the model group,the positive control group,the ethanol extract low,middle and high dose group. Each group had 10 mice. Acute hepatic injury model of mice was made by using CC14. The level of ALT, AST in blood serum and SOD,MDA in hepatic tissue were observed. The hepatic tissue was HE-stained conventionally and observed. Results Acute liver injury in mice could be successfully induced by CC14 ,as demonstrated by increased serum ALT, AST levels and severe histological observations. Pretreatment with the ethanol extract of vaccinium bracteatum thumb leaf indicated its potent protective effects on acute liver injury, as demonstrated by a significant decrease in ALT, AST and MDA. Conclusion The ethanol extract of vaccinium bracteatum thumb leaf had an obviously protective effect on acute liver injury induced by CC14, which could be due to its antioxidative stress effect.
