Objective To evaluate the effects of anisodamine on apoptosis in cardiomyocytes and inflammatory response in overtrained rats. Methods Twenty-four male Wistar rats, weighing 200-220 g, were randomly divided into 3 groups ( n = 8 each) : control group (group C) , overtraining group (group O) , anisodamine group (group A) . The model of overtraining-induced acute heart injury was established by exhausting swimming. Anisodamine 10 mg/kg was given intraperitoneally 20 min before overtraining in group A. Blood samples were taken at 6 h after overtraining for measurement of serum CK-MB activity. The rats were then sacrificed and myocardial tissues taken for determination of TNF-α content and NF-κB activity (by immunohistochemistry) . The apoptosis rate was detected by flow cytometry. Results The CK-MB activity, apoptosis rate, TNF-α content and NF-κB activity were significantly higher at 6 h after overtraining in groups O and A than in group C, while lower at 6 h after overtraining in group A than in group O ( P < 0.05) . Conclusion Anisodamine can inhibit apoptosis in cardiomyocytes by reducing inflammatory response in overtrained rats.

Objective To investigate the infection prevention effect of prophylactic use of antibiotics for cancer inpatients with leukocyte count ≤ 1 × 109/L.Then to provide the basis for rational use of antibiotics.Methods It was retrospectively surveyed that the infection situation and prophylactic usage of antibiotics in the 426 cancer inpatients with leukocyte count ≤ 1 × 109/L caused by radiotherapy and chemotherapy.Results In the 426 inpatients,the infection rates of patients with and without prophylactic use of antibiotics were 11.0％ and 20.9％ respectively.The difference was statistically significant (x2 =6.815,P =0.009).The leukocyte count median values of patients with and without infection were 0.73 × 109/L and 0.77 × 109/L respectively.The difference had no statistical significance(Z =-1.257,P =0.209).The main infection sites were lower respiratory tract,upper respiratory tract and gastrointestinal tract with infection rates of 48％,12％ and 11％,respectively.The top five pathogens were Klebsiella pneumonia,Enterobacter cloacae,Escherichia coli,Enterobacter aerogenes and Staphylococcus aureus.The most use of antibiotics were cephalosporin.Conclusion When the leukocyte counts of cancer inpatients are less than or equal to 1 × 109/L induced by chemotherapy and radiotherapy,reasonable prophylactic use of antibiotics can reduce hospital infection rates.

Objective To retrospectively analyzed the current application of warfarin in hospitalized patients with non-valvular atrial fibrillationand ( NVAF), explore the key role of clinical pharmacists in warfarin medication. Methods A retrospective survey of anticoagulant therapy for 179 hospitalized patients with non-valvular atrial fibrillation in Renming Hospotal of Wuhan University from January to December 2013 was retrived,including the usage of warfarin for NVAF and new-onset atrial fibrillation,dosage,international normalized ratio(INR),hemorrhage event and so on.The simple factor like the age,complicated chronic diseases and previous cerebrovascular events on the use of warfarin was explored. Results The total response rate to anticoagulants was 85.6% for patients with high risk of stroke(27.3% with warfarin and 58.3% with antiplatelet therapy),who are recommended to use warfarin,patient were treated with anti-thrombotic therapy.The total of 19.1% of the patients with new-onset atrial fibrillation used warfarin as therapy.The whole monitoring rate of INR was 89.8%,and the good control rate was 11.9%. Univariate analysis showed that some high risk factors such as age and high blood pressure affected the usage of warfarin. Conclusion The anti-thrombotic therapy for NVAF patients in the hospital is good,but usage of warfarin for those with new-onset atrial fibrillation is low,which couldn't reach the INR standard. More attention should be taken by the clinic pharmacists in effective managing the use of anticoagulant to build a safe,economic and effective medication system for warfarin application.

Objective To investigate the changes in trafficking of GluRl-containing AMPA (GluR1-AMPA) receptor and GluR2-AMPA receptor from cytoplasm to cell membrane in the spinal cord dorsal horn in a rat model of incisional pain.Methods Thirty-two adult male SD rats aged 6-8 weeks weighing 280-300 g were randomly divided into 2 groups:control group (group C,n =8) and incisional pain group (group Ⅰ,n =24).An 1 cm long incision was made in the plautar surface of right hindpaw according to Brennan et al.in group Ⅰ.Cumulative pain score (CPS) and paw-withdrawal threshold to yon Frey stimuli (PWT) were measured at 3 h and day 1 and 3 afar incision ( T1,2,3 ).The animals were sacrificed after pain behavior assessment.Their lumbar segments of the spinal cord (L3-6) were removed.The expression of GluR1 and GluR2 in cell membrane and cytoplasm in spinal cord dorsal horn was determined by Western blot analysis.The co-expression of Stargazing with GluR1 and GluR2 in the spinal cord dorsal horn was examined by co-immuno-precipitation.Results The CPS was increased and PWT decreased; the GluR1 expression in cytoplasm was decreased while the expression of GluR1 in cell membrane and the co-expression of Stargazing with GluR1 were up-regulated in group Ⅰ as compared with group C.There was no significant change in the expression of GluR2 in cytoplasm and cell membrane and the co-expression of Stargazing with GluR2 in group Ⅰ as compared with group C.Conclusion GluR1-AMPA receptor transfers from cytoplasm to cell membrane but GluR2-AMPA receptor does not in rats with incisional pain.

Objective To study the effect of different concentration of 1,25-dihydroxyvitamin D3[1,25(OH)2D3] on cell proliferation,differentiation and the expression of vitamin D receptor (VDR) in mouse MC3T3E1 osteoblast.Methods Osteoblast were cultured in medium with different concentrations of 1,25(OH)2D3.Incubated for 48 h,cell proliferation of osteoblast were examined by MTT reduction assay (mono-nuclear cell direc cytotoxicity assay),the osteocalcin (OC) levels in cell medium were detected by ELISA,and the expression of VDR mRNA and protein were examined by using SYBR Green real-time PCR and Western blot,respectively.Results 1.After incubation with 1,25(OH)2D3 for 48 h,the number of MC3T3E1 osteoblast was significantly less than that in control group(P0.05).3.SYBR Green real-time PCR and Western blot results showed that the expression of VDR mRNA as well as VDR protein of osteoblast in 10-8,10-9 mol/L experimental groups were significantly higher than those in control group (Pa0.05).Conclusions Cell proliferation of mouse osteoblast can be inhibited,while the cell differentiation was promoted by 1,25(OH)2D3.1,25(OH)2D3 up-regulated the expression of VDR in mouse osteoblast,which suggested that the VDR signal pathway may play some role in proliferation and differentiation of osteoblast.

AIM: To investigate the alterations of tear film after sutureless large incision manual cataract extraction (SLIMCE). METHODS: Sixty-eight SLIMCE operation eyes were studied with slit-limp microscope, break- up time (BUT), SchirmmerⅠtest (SⅠt),and fluorescence(FL) to observe the alterations of tear film at different time points in postoperation. Impression cytology and microphoto-analyses technique were also applied to observe the goblet cells at different time points postoperation(7,14,30,60,90 days). RESULTS: Subjective complaint of dry eye within 90 days after the operations were significantly increased compare with preoperations(5-27,23,19,16,13; 2-16,14,8,6,3). The schirmmer Ⅰ test were greatly increased in 14 days postoperation(10.1±4.5;15.0±4.7,13.8±5.7),the mean scores of fluorescence increased (0-17,9,5;0-8,3,1) and the mean break-up time decreased in 30 days post-operation(10.3±2.2;5.5±2.3,7.0±2.4,7.9±2.2) (P<0.05). CONCLUSION: SLIMCE operation have effect on the stability of tear film.

AlM:To find better ways of treating ocular alkali burn, and to reduce the suffering of patients and social burden.METHODS:Totally 100 patients were graded according to the degree of chemical burns to four major groups, each half were randomly divided into the control group and the treatment group. Control group underwent conventional treatment. ln addition to conventional therapy, patients in each treatment group were also added a Breviscapine intravenous injection of 40mg daily. Corneal recovery time, changes in vision, degree of corneal opacity, number of corneal neovascularization and other complications were observed. Curative effects were analyzed statistically.
RESULTS:There was no significant difference in levelⅠgroup between control group and treatment group ( P>0. 05); There were significantly different in level Ⅱ, Ⅲand Ⅳ group ( P<0. 05 ). Compared to the degree of corneal opacity and the number of corneal neovascularization, the treatment group was obviously better than the control group(P<0. 05).
CONCLUSlON: Breviscapine in the treatment of ocular alkali burns can shorten the course of treatment, reduce corneal scarring, and improve vision.

AlM:To analyze and compare the effect of femtosecond laser micro - incision corneal stromal lens excision ( SMlLE) and excimer laser in situ keratomileusis ( LASlK) in the treatment of myopia after operation, to explore the safety, operability and prediction of SMlLE.METHODS:ln this prospective clinical controlled study, 100 cases ( 200 eyes ) received SMlLE and 100 cases ( 200 eyes) undergone LASl in our hospital in the same period were selected. Uncorrected visual acuity, diopter, corrected visual acuity, slit lamp examination, intraocular pressure and corneal anterior segment OCT, corneal topography (Obscan ll) of two groups in 1d, 1wk, 1, 3, 6mo, 1a were compared. lndependent samples t test was used for data analysis.RESULTS:1) Postoperative slit lamp examination:after 1d in SMlLE group, there were less eyes had corneal layer between mild cloudy or edema; postoperative 1wk corneal layer disappeared, cornea became clear and transparent. 2 ) Postoperative vision recovery: 1d after operation, vision recovery in LASlK group was better than that in SMlLE group, the difference was statistically significant (P<0. 01), there were no significant differences at 1wk, 1, 3, 6mo, 1a after operation ( P>0. 05 ). 3 ) Obscan ll examination: graphics in the SMlLE group was more regular and placed in the center, no eccentric and irregular graphics, better than that in the LASlK group. 4) Anterior segment OCT examination:postoperative corneal flap in the SMlLE group was more uniform and accurate, but it was thin in the center and slightly thick the peripheral part in the LASlK groups. 5 ) Postoperative visual quality assessment used subjective questionnaire survey. The two groups had statistically significant difference on 4 points and 1 points (P<0. 05). Complains in the LASlK groups were more that that in the SMlLE group. While, no complain of the SMlLE group was higher than that of the LASlK group. Glare of postoperative patients with night vision and dark environment in the SMlLE group was better than that of the LASlK group.CONCLUSlON: SMlLE is safe, effective, stable and predictable for the correction of myopia.
