Based on the implementation of GMP, comprehensive improvement of quality control measures, and consideration of the 3Rs principle for experimental animals, Several years ago, WHO, the European Pharmacopoeia and the FDA gradually abolished the testing for abnormal toxicity of biological products, and the Chinese Pharmacopoeia 2025 Edition(Volume Ⅲ)also revised the testing for abnormal toxicity of biological products. In order to help users of the Chinese Pharmacopoeia(Volume Ⅲ) better understand and implement this pharmacopoeia, this article provides a detailed review of the changes in regulatory concepts for abnormal toxicity test in various countries and the process of gradually phasing out abnormal toxicity test, as well as the actual situation of China’s pharmaceutical industry. It also interprets the ideas and considerations for revising the Chinese Pharmacopoeia 2025 Edition(Volume Ⅲ) on abnormal toxicity test for biological products.

Objective To understand the status of infection with multidrug-resistant organisms (MDROs) in intensive care units(ICUs),and evaluate the intervention efficacy of targeted monitoring.Methods Prospective study was adopted,patients who were admitted to ICUs in 2014-2015 were selected (January-December 2014 was as preintervention stage,January-December 2015 was as intervention stage),trend of MDRO infection before and after intervention were compared and analyzed.Results Before and after intervention,297 and 217 strains of MDROs were isolated respectively,except carbapenem-resistant Pseudomonasaeruginosa (CRPA),the isolated strains of carbapenem-resistant Acinetobacterbaunannii (CRAB),carbapenem-resistant Enterobacteriaceae (CRE),methicillin-resistant Staphylococcus aureus(MRSA),and vancomycin-resistant Enterococcus (VRE) declined after intervention.MDRO infection rate declined from 7.17 ％ before intervention to 3.88％ after intervention,infection rate of CRAB and CRE after intervention were both lower than before intervention (both P＜0.05);MDRO infection rates in general ICU and internal medicine ICU increased from 8.75％ and 7.84‰ before intervention to 4.39‰ and 2.28％ after intervention,respectively (both P＜0.05).After taking comprehensive intervention measures,compliance to prevention and control measures,such as ordering rate of doctor's advice on contact isolation for 24 hours,hand hygiene,health care workers' awareness all enhanced significantly(all P＜0.05).Conclusion Targeted monitoring and intervention measures can reduce isolation rate of MDROs in ICUs.

Objective To investigate the efficacy of initial polytherapy in the patients with newly diagnosed infantile spasm by evaluating the ambulatory electronecephalogram (EEG) profiles and serum neuron specific enolase ( NSE ) level.Methods Data from 108 cases of newly diagnosed infantile spasm from Sep.2007 to Nov.2010 in the Department of Pediatrics,the First Hospital of Jilin University,were respectively analyzed for the EEG profiles and serum NSE level.The patients were treated with multiple drugs.Results ( 1 )After treatment,EEG showed normal shape in 56 cases ( 62.2％ ),sporadic sharp and slow waves without hypsarrhythmia in 32 cases( 35.6％ ),and hypsarrhythmia in 2 cases (2.2％).The overall effective rate was 97.8％.(2) Serum NSE in 35 seizure-free cases were examined at the time points of hospital admission,48 hours and one month after seizure cessation,respectively.NSE level was significantly decreased at 48 hours after seizure control than that at hospital admission ( t =6.54,P ＜ 0.05 ) ; NSE at one month after seizure free was further decreased compared with that at admission point ( t =9.29,P ＜ 0.05 ).Conclusion Polytherapy for infantile spasms can ameliorate the abnormal EEGs.NSE level is decreased after seizure cessation.Intelligence is improved 6 months after seizure free and polytherapy may improve the prognosis of the children with infantile spasms.

Objective To explore the effect of aldosterone on renal epithelialmesenchymal transition in streptozocin(STZ)-induced diabetic nephropathy rats. Methods Wistar rats were intraperitoneally injected with STZ(60 mg/kg)for the preparation of diabetic model.After 4 weeks,the rats with urinary protein＞30 mg/d were regarded as successful diabetic nephropathy(n=16),and were randomly divided into diabetic nephropathy(DN group,n=8)and spironolactone group(SP group,n=8).Then eight healthy rats were selected randomly as control group(N group,n=8).SP group rats were treated with spironolactone 40 mg·kg-1·d-1,and N group and DN group rats were given equal water.After 8 weeks,rats were sacrificed to collect urine,blood plasma,kidney tissue for detection of 24 h urinary protein,creatinine and renal pathological changes.Aldosterone concentration in plasma and kidney tissue was detected by mdioimmunoassay;E-cadherin,α-SMA protein expression by immunohistochemistry,Western blotting; E-cadherin,α-SMA mRNA expression by RT-PCR. Results Compared with N group,serum creatinine, urinary protein excretion in the DN rats were significantly higher (P＜0.01,respectively), E-cadhefin protein and mRNA were significantly reduced (P＜0.01, respectively),α-SMA protein and mRNA expression was up-regulated (P＜0.01, respectively). Aldosterone level of kidney tissue in DN rats was increased obviously [(24.71±5.30) ng/g vs (16.38±2.85) ng/g, P＜0.01], which was positively correlated with urinary protein excretion, serum creatinine and α-SMA protein (r=0.737, 0.574, 0.688, P＜0.01, respectively), and negatively correlated with E-cadherin protein (r=-0.659, P＜0.O1). While no significant difference was found in serum aldosterone among three groups. Compared with DN rats, urinary protein excretion, serum creatinine were reduced (P＜0.01, respectively), E-cadherin protein and mRNA were increased (P＜0.01, respectively), α-SMA protein and mRNA expression were decreased (P ＜0.01, respectively) in SP group rats.Conclusions Local aldosterone involves in renal epithelial-mesenchymal transition in diabetic nephropathy rat. Spironolactone can block the effect of aldosterone and play a role in renal protection.
