Objective To evaluate the rationality of medication in Pediatric Intensive Care Unit (PICU).Methods The medication of 46 children in PICU of the First Affiliated Hospital of Sun Yat-Sen University with the average age of (34.74 ±45.5) months during May 3, 2011 and December 5, 2011 were retrospectively analyzed.The study was conducted statistically on the basis of pharmacopoeia, medical documents and other related medical materials.Results Among 46 ca-ses, irrational drug use was found in 28 patients (60.87%).A total of 100 irrational drug using habits such as potential drug interactions and incompatibility were presented.Compatibility taboo and pDDIs top four drugs were16 cases of furosemide (16%), 12 cases of vancomycin and dexamethasone (12%), 11 cases of midazolam injection (11%), and 9 cases of Phe-nobarbital (9%).Conclusion According to the characteristics of pediatric medication, pharmacists should take advantage of drug synergy when vigilant about the side effects of multi -medication, especially paying close attention to the potential inter-action of some commonly-prescribed drugs as well as reducing the prescriptions of multi -medications in order to improve the rationality of drug use in PICU.

[Objective]To discuss the relation-ship between AAONFH(advanced alcoholic osteonecrosis of femoral head)and extended overdose drinking.[Method]Reviewed 165 cases of total hip arthroplasty,to analyzed the clinical data among 27 AAONFH cases,reviewed the literatures,discussed the pathogenesis of AAONFH and the relation-ship between blood biochemistry and blood cloting funtion and compared the experimental results among literatures.[Result]Theres various factors resulted in osteonecrosis of the femoral head associated with alcohol long-term over intake.Individuals consuming more than 750 ml of alcohol daily were at greater risk of double or half ONFH,Theres no change in biochemical test,but blood clotting funtion in this case would degrade,osteoarthritis of hip would synchronize.[Conclusion]Individuals consuming more than 750 ml of alcohol daily have the potentiality of ONFH;Its no specificity significance in biochemical test,the necrosis extent of the femoral head is relative to the capacity and times of alcohol intake.THR(total hip replacement)is the best treatment for AAONFH,but theres more staxis potentiality in this cases.

Objective To study the significance of detecting the mutations of K-ras gene in faecal for diagnosis colorectal carcinoma.Methods 36 cases suffering from colorectal carcinoma,24 cases from colorectal benign diseases and 24 cases from healthy subjects,all cases had been diagnosed by enteroscope. K-ras gene mutation at the codon 12 was detected by PCR-RFLP,DNA was taken from faecal in modified method.Results K-ras mutation rate in colorectal carcinoma was 77.8 %,colorectal benign diseases was 25.0 %,healthy cases was 8.3 %.Conclusion Detecting the mutations of K-ras gene in faecalmay improve the rate of diagnosing colorectal carcinoma.

The activation of coagulation system,especially in the occurrence and development of cardiogenic cerebral embolism,plays an important role.As one of the major preventive measures in ischemic stroke,the anticoagulant therapy is getting more and more attention.At the same time,the studies of anticoagulant drugs aiming to the intervention of different links in coagulation pathway have also made significant progress.

AIM: To study the changes in anterior chamber angle after phacoemulsification and foldable IOL implantation with ultrasound biomicroscopy.METHODS: Small-incision phacoemulsification and foldable IOL implantation were performed in 50 eyes of 46 senior patients, and the changes of anterior chamber angle were determined quantitatively by using ultrasound biomicroscopy before and one month after the surgery.RESULTS: In all patients, the angle was widened significantly one month after the surgery (P＜0.01). The measurements of TIA500 ( trabecular-iris angle at 500μm from the scleral spur) , AOD250 (angle-opening distance at 250μm from the scleral spur) and AOD500 (angle-opening distance at 500μm from the scleral spur) increased significantly after the operation ( P＜ 0.01). The mean post/pre-operative TIA500ratio, AOD250 ratio and AOD500 ratio were 1.65 (1.12-4.91),1.81 (1.06-2.67) and 1.65 (1.01-2.76), respectively. A significant negative correlation existed between preoperative and postoperative data.CONCLUSION: Small-incision cataract surgery deepens the anterior chamber and widens anterior chamber angle significantly in senior patients. The narrower the preoperative angle, the higher ratio of post/preoperative ratio found.

Objective To evaluate the efficacy of entecavir in lamivudine-refractory patients with chronic hepatitis B.Methods Literature from Medline,Embase and CBM between January 2001 to December 2008 were reviewed.Acccording to the including and excwding criteria,four randomized controlled trials (RCT) were enrolled.The results of the trials were reviewed and analysed in software Revman 4.2.Results Patients in the entecavir group enjoyed significantly higher negative conversion ratios of HBV-DNA and ALT,and positive seroconversion of HBeAg:RR were 13.90(95% CI 6.39～30.24,P＜0.00001),2.49(95% CI 1.40～4.45,P=0.002),and 3.53 (95% CI 2.85～4.38,P＜0.000 01) respectively.There was a trend for the improvement of negative conversion ratio of HBeAg (RR=2.27,95% CI 1.00～5.15,P=0.05),but the incidence of side-effects of the drugs has no difference (RR=1.05,95% CI 0.97～1.14,P=0.21).Conclusions Compared with lamivudine or placebo,entecavir can significantly decrease HBV-DNA,improve liver function and positive seroconversion ratio of HBeAg without raising the incidence of drug side-effects.

OBJECTIVETo evaluate the clinical effect and safety of dapoxetine in the treatment of premature ejaculation (PE).

METHODSWe randomly assigned 116 PE patients to receive dapoxetine on demand at 30 mg qd (dapoxetine group, n = 60, aged 23-49 years) or oral tamsulosin at 20 mg qd (control group, n = 56, aged 24-46 years). After 4 weeks of medication, we compared the clinical global impression of change (CGIC) , PE profile (PEP) scores, intravaginal ejaculation latency time (IELT) , and adverse reactions between the two groups of patients.

RESULTSCompared with the baseline, the IELT was remarkably prolonged after treatment both in the dapoxetine group ([0.86 ± 0.17] vs [4.32 ± 2.23] min, P < 0.05) and the control ([0.88 ± 0.15] vs [4.17 ± 2.26] min, P < 0.05), with no statistically significant difference between the two groups (P > 0. 05). The post-treatment rate of CGIC in the dapoxetine group had no statistically significant difference from that in the control (85.00% vs 82.14%, P > 0.05). In comparison with pre-treatment, the patients of both the dapoxetine and control groups showed dramatically improved scores after medication in perceived control over ejaculation (0.85 ± 0.23 vs 2.13 ± 0.97 and 0.88 ± 0.21 vs 2.06 ± 0.34, both P < 0.05), ejaculation-related personal distress (1.15 ± 0.64 vs 2.89 ± 0.26 and 1.19 ± 0.53 vs 2.82 ± 0.69, both P < 0.05), satisfaction with sexual intercourse (0.81 ± 0.33 vs 2.58 ± 0.37 and 0.79 ± 0.28 vs 2.45 ± 0.32, both P < 0.05), and ejaculation-related interpersonal difficulty (2.05 ± 0.61 vs 3.24 ± 0.35 and 2.03 ± 0.65 vs 3.18 ± 0.76, both P < 0.05), with no significant differences between the two groups (P > 0.05). The incidence of adverse reactions was significantly lower in the dapoxetine than in the control group (3.33% vs 30.36%, P < 0.05).

CONCLUSIONDapoxetine is effective for the treatment of PE, with its advantages of prolonging the intravaginal ejaculation latency time, improving the quality of sexual life, and low incidence of adverse reactions.
