AIM: To evaluate the efficacy and safety of neurotropin in the treatment of neuropathic pain.METHODS: A systematic literature search was performed in biomedical database including MEDLINE,EMBASE, Cochrane Central Register of Controlled Trials, CBM and CNKI. All studies focused on the clinical controlled trials, especially randomized controlled trials (RCTs) . The outcome measures included efficacy,life quality, cost of the treatment and adverse reactions. Quality assessments of clinical trials were evaluated with Jadad Score. Meta-analysis of included studies was performed with Revman software. RESULTS: Twenty-six clinical trials were included. Jadad Score of 24 trials was less than 3, which indicated the poor quality of the trials. None of the clinical trials evaluated the changes in life quality and cost related to neurotropin treatment.Meta analysis of 11 trials indicated neurotropin was more effective than placebo or blank, and the odds ratio of efficacy was 3.84 [2.68, 5.50] . The combining effect of 6 RCTs showed that neurotropin decreased the pain scores measured by Visual Analog Scale significantly compared with placebo or blank, the weighted mean difference (WMD) was -1.76 [-2.31, -1.21] . The pooled effects of the trials comparing neurotropin with other pain relieving drugs such as earbamazepine or NSAIDs also showed positive effect favored neurotropin.Neurotropin had no more adverse reactions than placebo, carbamazepine or NSAIDs, and the pooled risk difference was -0.01 [-0.04, 0.02] . CONCLUSION: According to present evidence, neurotropin may be effective and safe in the treatment of neuropathic pain. However, the poor quality of the studies decreases the persuasion of the results. Large-scale and well-designed RCTs with enough follow-ups should be carried out to provide further evidence for the use of neurotropin in neuropathie pain.

Objective To investigate clinical effect of patients with PICU multiple organ dysfunction by continuous blood filtration combined with naloxone.Methods 42 patients with multiple organ function failure were selected and randomly divided into 2 groups.The control group were treated by PICU conventional therapy, the experiment group were treated by continuous blood filtration combined with Naloxone.Vital signs, creatinine, creatine kinase and aspartate aminotransferase levels, length of stay and blood filtration were compared after 1 day and 3 days treatment.ResuIts Compared with control group,heart rate, oxidation index,creatinine and aspartate aminotransferase levels of the experiment group were lower(P<0.05).After 1 day and 3 days, compared with cnontrol group, length of stay and blood filtration of the experiment were lower(P<0.05).ConcIusion Continuous blood filtration combined with naloxone in treatment of multiple organ dysfunction syndrome PICU is effective and reliable.It can significantly improve renal function, shorten the length of hospital stay, and remove inflammatory mediators in plasma of patients.

OBJECTIVE:To assess the effectiveness of 1,6—diphosphate fructose(FDP)in the treatment of heart failure(HF).METHODS:Biomedical databases,including Medline,Embase,Cochrane Controlled Trials Register,CBM and CNKI were searched.Clinical trials were screened according to the inclusion criteria formulated beforehand,quality assessments and meta anylysis of included studies were carried out.RESULTS:14 randomized controlled trial were included,and all of them were carried out in China.Jadad score of the studies were all 1.None of the 14 trials carried out by follow-up domization for long-term effect evulation Meta-analysis of 14 trials showed that FDP can increase effective rate in the treatment of HF,and OR(95%CI)was 3.79(2.58,5.57).5 studies showed that FDP can increase cardic index,and WMD(95%CI)was 0.40(0.34,0.46).6 studies showed that FDP can increase ejection fraction(EF)with WMD(95%CI)8.31(5.51,11.11).4 studies showed that FDP can decrease left ventricular end systolic and diastolic diameter,and WMD was—3.25(—4.74,—1.76)and—3.75(—6.94,—0.56).No long-term effects were reported by the included studies.CONCLUSIONS:According to present evidence,FDP can increase the treatment effective rate when added to the basic treatment of HF.FDP can improve heart function and lefe ventricular construction showed by the indicators.However,the poor quality of the studies decreased the persuasion of the results.Large-scale and well-designed RCTs with enough follow-ups should be carried out to provide further evidence for the use of FDP.

Objective To study the effect of transient intensive insulin treatment on the serum free fatty acid (FFA) in newly diagnosed type 2 diabetic patients.Methods Sixty-four newly diagnosed type 2 diabetic patients were treated with transient intensive insulin.The fasting plasma glucose (FPG),2 hours post-prandial glucose (2hPG),lipid,fastin insulin (FINS),and serum FFA was examined hefore and after treatment.Results The levels of FPG,2hPG,total cholesterol (TC),triglycerides (TG),low density lipoproteins cholesterol (LDL-C),FFA and HOMA-IR after treatment were (9.68 ± 2.02) mmol/L,(12.77 ± 1.35) mmol/L,(4.26 ± 1.07) mmol/L,(1.52 ± 0.58) mmol/L,(2.50 ±0.75) mmol/L,(435.84 ± 190.94) μmol/L,0.51 ± 0.62,and they decreased obviously compared with those before treatment [(14.66 ± 3.50) mmol/L,(17.43 ±4.89) mmol/L,(5.03 ±0.94) mmol/L,(2.05 ± 1.42) mmol/L,(2.91 ±0.78) mmol/L,(586.68 ±229.45)μmol/L,0.65 ± 0.89](P＜0.05).The level of HOMA-β increased obviously (2.70 ± 0.83 vs.1.74 ± 1.04)(P＜0.05).The increase of HOMA-β and the decrease of HOMA-IR was positively correlated with the decrease of FFA.Conclusion The transient intensive insulin treatment can evidently decrease the level of FFA that can improve beta-cell function and relieve insulin resistance in newly diagnosed type 2 diabetic patients.

Objective:To analyze the intervention effect of a successfully created platform“intelligent interactive software for drug monitoring warning” on the decrease of medication errors and adverse drug events,and the increase of the drug treatment level. Meth-ods:The intensive care unit ( ICU) of our hospital was selected as the experiment group, and the ICU of the other two hospitals was used as the contrast group. During the first 18 months, both groups were without intervention. During the latter 18 months, the plat-form was used in the experiment group, and the clinical pharmacists employed alerts of the system in the practice of interaction with doctors to correct the medication errors. No intervention was performed in the contrast group. In addition, all adverse drug events in both groups were surveyed. Results:During the first period, 50 preventable adverse drug events were discovered with the incidence of 6. 8% in the experimental group. During the second period, the correct rate of the alerts was 97. 7%. Through the effective interven-tion,the alerts and their percentage in the prescriptions were from the maximum of 68 and 1. 1% to the minimum of 6 and 0. 1%. To-tally 17 preventable adverse drug events were found with the incidence of 2. 4% after the intervention. The decline was significant, 848 991 yuan of hospitalization expenses was saved, and 294 days of the length of stay were shortened. There was no change in the contrast group, and there was no change in unpreventable adverse drug events in the two groups before and after the intervention. Conclusion:The intelligent interactive software for drug monitoring warning can examine many sorts of medication errors,and decline the inci-dence rate of preventable adverse drug events in ICU. However, it needs to continuously improve the intelligence. Clinical pharmacists need to master the relevant conditions of patients to detect the irrational drug use based on the clinical practice for each patient.
