Objective:To assess the efficacy and safety of Zyrtec drops which is a patent product of UCBpharma in treatment of allergy rhinitis in children. Method :A total of 47 children of both sexes aged between 2 to6 years with allergy rhinitis (AR) were included in this study,who were randomly selected to be treated withZyrtec (Cetirizine 2 HCL) drops 5 mg daily for 3 weeks. Investigators made a global evaluation with symptomscores before treatment and once a week for 3 weeks after treatment. Result:An improvement was shown in eachweek after treatment with statistical significance (P＜0.01). Zyrtec drops provided an excellent improvement atthe end of the study. Tolerance was good. Conclusion :For acting fast ,potent ,good tolerance and convenience inuse,Zyrtec drops is a better treatment in AR in kids.

OBJECTIVE:To evaluate the derma safety of miconazole and chloramphenicol cream (MCC) for Guinea pigs.METHODS:Blank matrix,positive sensitizing agent (2,4-dinitro-chlorobenzene) and MCC (high dose and low dose) were applied on normal or damaged areas of the unhairing backs of Guinea pigs to conduct acute toxicity test,sensitivity test and irritation test,respectively.RESULTS:MCC caused no acute toxicity when applied on the skin of Guinea pigs,nor skin/systemic hypersensitive reaction was noted after repeated sensitization.Single or multiple dosing of MCC caused no irritation on normal skin of Guinea pigs but caused mild irritation on damaged skin which disappeared after 48 h or 72 h.CONCLUSION:MCC has good dermo safety for Guinea pigs.

Objective To explore the effects of quetiapine combined with sertraline in the treatment of schizophrenia patients with depressive symptoms.Methods 86 patients of convalescence of schizophrenia with depression symptoms were randomly divided into quetiapine combined with sertraline group(observation group) and quetiapine group(control group).The treatment course was 8 weeks.Before and after treatment,the positive and negative symptoms scale (PANSS) and Hamilton depression scale (HAMD) were assessed in the two groups.The curative effect of quetiapine combined with sertraline on the schizophrenia patients with depression symptoms was explored.Results Pre-treatment,there were no differences in the two groups on PANSS score (t =-0.432,P ＞ 0.05),HAMD score (t =0.424,P ＞ 0.05).Post-treatment,there were significant differences between the two groups in PANSS score (t =18.780,P ＜ 0.05;t =12.256,P ＜ 0.05) and HAMD score (t =6.542,P ＜ 0.05;t =4.107,P ＜0.05).There were significant differences between the two groups in HAMD score (t =6.612,P ＜0.05).Conclusion Quetiapine can significantly improve the effects of positive and negative symptoms and depressive symptoms of schizophrenia patients with depression symptoms.Quetiapine combined with sertraline can improve the depressive symptoms of schizophrenia better compared with quetiapine.

Conclusion:The medicine phantom study specialized is an emerging medicine specialty, should strengthen the organization in the clinical practice teaching important stage to manage, arranges various branches reasonably the practice time, emphasized the fundamental training, sharpens the generalized analysis ability, trains the qualified talented person.

RNA interference(RNAi),the first method of choice to suppress gene expression in vitro,is a conserved biologic response to double-stranded RNA that resulted in the sequence-specific silencing of target gene expression.Recently,more than 100 literatures reported synthetic small interfering RNAs in mammals.These reports demonstrated that RNAi is also a powerful tool for in vivo research and may become an effective therapeutic tool.This paper reviews the influencing factors and experimental design of in vivo use of RNAi.

ObjectiveTo retrospectively investigate the incidence,outcome and risk factors of HBV reactivation in HBsAg-positive a patients with gastric carcinoma during cisplatin-based adjuvant chemotherapy.Methods We retrospectively reviewed the records of 2,538 patients with gastric carcinoma who received adjuvant chemotherapy from January 2005 to December 2010.Among these patients,146 HBsAg-positive patients were analyzed for the HBV reactivation in this study.The HBV serology and biochemical tests of the 146 patients were performed.The data were analyzed by chisquare test.Results Among 146 HBsAg-positive patients with gastric carcinoma,43 patients (29.5％) developed hepatitis,of which 29 (19.9％) were related to HBV reactivation.Univariate analysis showed that age ≥51 years (P=0.029) and abnormal liver uhrasonography findings such as fatty liver or early cirrhotic changes (P=0.031) were associated with HBV reactivation.However,gender,HBeAg positive status and the use of corticosteroids were not related with HBV reactivation.Conclusions HBV reactivation occurs in a significant proportion of HBsAg-positive patients with gastric carcinoma during adjuvant cisplatin-based chemotherapy.Once hepatitis developed,most patients could not finish the chemotherapy as planned despite lamivudine treatment.Therefore,HBsAg-positive gastric carcinoma patients should initiate prophylactic antiviral treatment before chemotherapy.

Objective To observe the expressional changes of pro nerve growth factor(proNGF)apoptosis pro-signal factors after cerebral ischemia and reperfusion and discuss the protective effect of mild hypothermia on the brain injury. Methods The randomly chosen female SD rats weighing(220±10)g were divided into normal control group(Group A),cerebral isehemia and reperfusion group (Group B)and mild hypothermia group(Group C).Groups B and C were divided into 3,6 and 9 hours subgroups(eight rats per group).TUNEL methods was used to detect the apoptotic cells in the cortex after cerebral ischemia and reperfusion and treatment with mild hypothermia.The reverse transcription polymerase chain reaction(RT-PCR)was used to detect the expression changes of proNGF,Sortilin and P75gene in the cortex. Results (1)The apoptotic cells were increased with time in the Group B(P<0.05)and were more than those in the Group C in the same time point(P<0.05).(2)There found expression of all factors at all time points in three groups,which was increased with time(P<0.05).(3)The content of every factor at each time point in the Group C was less than that in the Group B(P<0.05). Conclusions (1)Mild hypothermia can decrease the apoptosis after ischemia and reperfusion injury.(2)The cell apoptosis induced by proNGF plays a very important role in the COUrse of cerebral ischemia and reperfusion injury.(3)Mild hypothermia can decrease the expression of apoptosis pro-signal to alleviate the cell apoptosis and protect the brain from ischemia and reperfusion.

Environmental enrichment has become a hot topic in laboratory animal science , which is intended to im-prove the well-being of laboratory animals .This paper reviews the research in this area , focusing especially on the princi-ple and procedure of planning enrichment strategies .The consideration of housing laboratory animals should not only focus solely on animal well-being, manpower and economics , but also on the precision and accuracy of the experimental results . It also introduces the type of environmental enrichment and practice in widespread use currently .

ObjectiveTo compare the differences in stroke subtype classification between ASCO and modified TOAST.MethodsAll 425 first-ever ischemic stroke patients were recruited and classified into different stroke subtypes according to the ASCO and modified TOAST criteria.Results Comparing ASCO grade 1 with modified TOAST,more patients were classified as atherosclerosis (60.2％ vs 57.9％ ; x2 =2.68,P=0.132) and fewer as small artery disease and cardiac disease subtype (13.4％ vs 14.8％ and 8.5％ vs 8.7％ ; x2 =1.30 and 0.00,P =0.238 and 1.000,respectively).ASCO grade 1 did not reduce the proportion of cause undetermined patients compared with modified TOAST ( 15.5％ vs 16.2％ ; x2 =0.09,P =0.795 ). Agreement was showed in every subtype categories between the two approaches.Agreement for atherosclerotic cause and small artery disease was very good ( all κ over 0.81 ),and for the cardiac disease subtype was good (κ: 0.61-0.80). Conclusion Agreement can be found in every subtype categories between ASCO and modified TOAST classification.ASCO grade 1 does not reduce the proportion of cause undetermined cases compared with modified TOAST,but the subtype categories characteristics of the two approaches should be considered in practice.
