Objective To establish a method for the quantitative determinations of the ingredients in yiqi hewei capsules. Methods RP-HPLC method was used. The separation was performed on a Thermo C18 column with mobile phase consisting of acetonitrile-water (20: 80) (pH was adjusted to 3 with glacial acetic acid) at the flow rate of 1. 0 mL·min-1. The detection wavelength was 283 nm. Results The linear ranges were ( 0. 5735 -5. 7360) × 10 -2 mg·mL-1 for baicalin, (0. 1940-1. 9395) × 10 -2 mg·mL-1 for hesperidin, (0. 2051 -2. 0510) × 10 -3 mg·mL-1 for naringin and (0. 2020 -2.0200) ×10 -2 mg·mL-1 for neohesperidin;RSD =0.28%,0.54%,0.54%,0.31%(n =5),respectively. The average recoveries were 103. 94%, 98. 06%, 103. 09%, 95. 67%, respectively. Conclusion The established method is simple, sensitive and accurate,which can be used for the quality control of yiqi hewei capsules.

Objective To study clinical effect of oral montelukast therapy in the treatment of 35 children with cough variant asthma.Methods 35 children with cough variant asthma were divided into the control group (17 cases)and observation group(18 patients).The control group was given oral procaterol hydrochloride,patients in the observation group were given oral montelukast sodium on the basis of taking procaterol hydrochloride.Results The total effective rate of the observation group (94.44%) was significantly higher than the control group (64.71%),the difference between the two groups was statistically significant (χ2 =4.832,P <0.05).In the two groups before and after treatment the maximum peak expiratory flow rate change had no statistically significant difference (P >0.05).After treatment,the FEV of the observation group (12.81 ±0.34)L was higher than that of the control group(2.32 ±0.45 )L,the difference between the two groups was statistically significant(χ2 =3.648, P <0.05).The FVC of the observation group (3.44 ±0.21)L was higher than the control group (2.98 ±0.15)L, the difference between the two groups was statistically significant (χ2 =7.417,P <0.05).The FEV1 /FVC of the observation group (68.31 ±6.44)was higher than that of the control group (58.46 ±6.49),the difference between the two groups was statistically significant (χ2 =4.505,P <0.05).The cough relief time of the observation group (4.45 ±1.32)d was lower than the control group (6.33 ±2.46)d,the difference between the two groups was statistically significant (χ2 =3.151,P <0.05).The cough symptoms disappear time of the observation group (7.63 ±1.96)d was shorter than the control group (10.61 ±1.84)d,the difference between the two groups was statistically significant (χ2 =4.639,P <0.05).In the two groups before and after treatment the liver and kidney function and blood,urine routine had no significant changes.No adverse reaction occurred during the treatment.Conclusion Steiner conven-tional therapy combined with montelukast in the treatment of children with cough variant asthma can rapidly relieve symptoms of cough,significantly improve lung function,reduce the recurrence rate,no adverse reactions,and signifi-cantly improve clinical efficacy,it is worthy of clinical application.

Objective To compare the efficacy and safety of recombinant insulin lispro and insulin lispro in the treatment of type 2 diabetes mellitus(T2DM ) .Methods Forty‐eight T2DM patients with poor blood glucose control were randomly assigned to the recombinant insulin lispro group (observation group ,n=32) and insulin lispro group (control group ,n=16) according to the ratio of 2∶1 .On the basis of injection of the recombinant insulin glargine once daily before sleep ,the two groups were given the re‐combinant insulin lispro injection or insulin lispro injection once before each meal .The period of treatment was 16 weeks .The levels of HbA1c ,2 h postprandial blood glucose(2hPG) and fasting plasma glucose(FPG) before and after treatment were measured and compared between the two groups .The adverse events were evaluated at the end of treatment .Results Forty‐four cases finished the study ,28 cases in the observation group and 16 cases in the control group .The levels of HbA1c ,FPG and 2hPG after 16‐week treatment in the two groups were decreased significantly (P<0 .05) .The decrease amplitudes of HbA1c in the observation group and the control group were (1 .55 ± 1 .50)% and(1 .06 ± 1 .30)% respectively ,which of FPG were (2 .07 ± 5 .01)mmol/L and (1 .09 ± 3 .18)mmol/L respectively ,and which of 2hPG declined (3 .28 ± 5 .71)mmol/L and(3 .60 ± 5 .89)mmol/L respectively . With HbA1c as the main evaluation index and 0 .40 as the non‐inferiority critical value ,non‐inferiority was found in the recombi‐nant insulin lispro injection as compared with the insulin lispro injection (P<0 .05) .The standard‐reaching rate of HbA1c less than 6 .50% in observation group was 14 .29% ,and which of HbA1c less than 7 .00% was 28 .57% ;in control group ,these two stand‐ard‐reaching rates were 18 .75% and 43 .75% respectively ,and there were no statistically significant differences between two groups (P>0 .05) .Conclusion The recombinant insulin lispro injection has non‐inferiority effects in the aspect of effectiveness compared with the lispro insulin injection ,moreover they have the same safety .

OBJECTIVE:To get a clear idea about current situation and trend of the application of eye drops in hospital of Shanghai so as to provide the information for rational clinical application and development of new preparations.METHODS:The kinds and amount of commercial eye drops,used in 47 hospital in Shanghai for the years 1997～2001,were analysed and evaluated.RESULTS & CONCLUSION:The amount of consumption of eye drops was increased year by year.The new type with good quality was received by clinical physicians.

Cell adhesion molecules (CAMs) are involved in glycoproteins expressed on cell surfaces which play an essential role in clinical disorders. At present, there are several groups of anti inflammatory drugs interfere with the expression of CAMs either directly or indirectly. This paper reviews the study of recent finding pharmacological agents associated with CAMs.

Objective To explore the related factors of the relapse of schizophrenics in unwell developed economic areas.Methods To analyze 718 schizophrenics by single and multiple stepwise regression analyses to explore whether relapse of schizophrenia was related to those factors.Results 2.8％ experienced one time relapse, 14.2％ experienced two times relapse and 83％ three times. The rate of schizophrenic relapse was in turn correlated with treatment compliance, treatment intervention, marriage, clinical features, psychological stress,social support, the way of forming disease, medical expenses and condition of access to medical care. Conclusions More attention should be paid to the factors causing schizophrenic relapse and wider measures of prevention and treatment should be taken.

Therapeutic hypothermia is believed to improve neurodevelopment outcome of infants with moderate-to-severe hypoxic-ischemic encephalopathy(HIE),however,the severe brain injury and neurologic sequelae still can be observed in some infants received therapeutic hypothermia.Optimal monitor and management of systematic complications presented by infants during cooling treatment are necessary for improvement of overall outcome.Therefore,it is essential to understand the functional change of each system of the whole body,to adapt adequate diagnostic methods and to train multidisciplinary staffs to monitor and manage moderate-to-severe HIE infants during therapeutic cooling.With the development of therapeutic hypothermia,it is currently considered as a standard of care for infants with moderate-to-severe HIE.It is recommended that any neonatal intensive care unit(NICU) using routinely therapeutic hypothermia to reference the national or international benchmarking protocols in order to improve the medical quality and prognosis of infants.

To date, three techniques of total spondelyctomy were used for spinal tumor, including piecemeal technique, eggshell technique and total en bloc spondelyctomy, and each has specific features and indications. Due to limitations of technique, piecemeal technique and eggshell technique are gradually replaced by total en bloc spondelyctomy in treatment of spinal tumor. Moreover, with technical development, application of total en bloc spondelyctomy in treatment of spinal tumor becomes more rigorous and standard. However, it is controversial about its indications and surgical approach. Postoperative spinal stability reconstruction is achieved through various methods according to different conditions.
