Objective To study the efficacy and adverse reactions of the treatment on different types of infantile hemangiomas (IH) with different doses of propranolol .Methods One hundred and fifty cases of IH without contraindications were randomly treated with different doses of propranolol (low dose group:1 mg?kg -1 ?d-1 ;high dose group:2 mg?kg -1 ?d-1 ) under ECG monitoring inferior half an hour to breastfeeding taking ,and stay in hospital for observation for 6 to 24 hours after the treatment . The patients returned to the hospital for review every month(ECG and blood RT ;lung function in necessary) .Results The curative effect is better on strawberry IH than that on flat IH ,also better on deeply IH than that on superficial IH .The adverse reactions oc‐curred relatively slight in the low dose group and there was no significantly statistical differences on the treatment effects between the both groups(P>0 .05) .Conclusion It is safe and effective to treat IH with propranolol .

The full length cDNA of ?1,3 galactosyltransferase gene was amplified by RT PCR from the peritoneal macrophages of BALB/c mice, which was subcloned into an eukaryotic expression vector pCDNA3 1/V5 HisA, and it was confirmed by DNA sequencing. The gastric cancer cell GC9811 was transfected with pCDNA3 1/V5 HisA?1,3GT by Lipofectamine TM 2000. The positive clone was screened by G418 for two months and confirmed by RT PCR. The gastric cells expressing Gal?(1,3)Gal epitope were detected by immuohistochemisty, and they were killed by naive antidoby specific to Gal?(1,3)Gal epitope. The results showed that the pCDNA3.1/V5 HisA?1,3GT was successfully constructed, and the transfected gastric cancer cells could highly express Gal?(1,3)Gal, which promoted lysis of the cancer cells by normal human serum.

MicroRNAs (miRNAs) are a class of highly conserved single-stranded RNA molecules that modulate gene translation. By targeting the mRNA of protein- coding genes, miRNAs play a critical role in neuronal differentiation, cell proliferation, apoptosis and metabolism. There are a lot of miRNAs in central nervous system, which are not only closely linked to development, differentiation and function of nerve cells, also play an important role in nerve lesions and dysfunction after cerebral ischemia. Specific miRNA through their own changes affect their target gene expression levels after focal cerebral ischemia, involving in the protection against apoptosis in neurons and regeneration after cerebral ischemia. A full understanding of the specific microRNA function and its underlying mechanism in the brain can provide a new strategy for the prevention, diagnosis, and treatment of ischemic cerebral injury at gene level.

To analyze the composition regularity of Carthami Flos-containing prescriptions of the Drug Standards of Ministry of Health of People's Republic of China-Traditional Chinese Medicine Preparations (the ministerial standards for Traditional Chinese Medicine) based on the traditional Chinese medicine inheritance support system (TCMISS, RZDZ No. 0389952). Efforts were made to identify 331 prescriptions containing Carthami Flos and summarize 16 attending functions and 10 commonly used drug combinations. Three commonly used drug combinations were selected for an in-depth analysis on Carthami Flos's combined administration regularity. Based on Carthami Flos's attending functions, its effects in paralysis, traumatic injuries and dysmenorrheal were compared to analyze Carthami Flos's core drug combinations for treating different diseases. The regularity of clinical administration and the characteristics of commonly used drug combinations were summarized to provide reference for Carthami Flos's clinical application and new ideas for new drug R&D. Carthami Flos prescriptions was mainly used to treat blood stasis and pain and mostly combined with drugs that could activate blood, promote the circulation of qi and dispel pathogenic wind to treat Qi-stagnation and blood stasis caused by various pathogenic factors such as wind, cold and dampness.

Objective To assess the in vitro affinity and apoptosis-inducing effect of 131I-K237 peptide (H-His-Thr-Met-Tyr-Tyr-His-His-Tyr-Gln-His-His-Leu-OH) to LNCaP prostate cancer cell line.Methods The K237 peptide was radiolabeled with 131I by the Iodogen method.The radiolabeling efficiency and radiochemical purity after purification were then characterized by TLC in vitro.LNCaP cells were inoculated in 96-well cell plate and divided into following groups (3 duplicate wells for each group):15 kBq 131I-K237was added in the experimental group,different doses of Na131I (5,10,15 kBq) were added in 3 negative control groups,15 kBq 131I-K237 with different doses of unlabeled K237 (1,2,4,8,16 μ g/μl) were added in 3 blocking groups,and PBS was added in blank control group.The cellular binding ratios were calculated after 48 h.LNCaP cells were inoculated in 24-well cell plate and divided into 3 groups:131I-K237group,which including 3 different dose subgroups (5,10,15 kBq) ; unlabeled K237 group,which including 3 different dose subgroups (1,2,4 μg/μl) ; blank control group with 100 μl PBS.All the cells were cultured for 48 h,then optical microscopy (OM) and fluorescence microscopy (FM) were used to observe the cell morphology ; DNA gel electrophoresis was conducted and flow cytometry (FCM) was used to estimate the apoptotic rate of LNCaP cells.One-way analysis of variance and the least significant difference (LSD)-t test were used to analyze the data.Results The labeling efficiency of 131I-K237 was (73.7±3.2) ％ and the radiochemical purity was (96.7±0.6) ％ after purification.The binding ratio of experimental group was (95.8±1.5)％,whereas the ratio of negative groups with 5,10,15 kBq Na131I and PBS group was (8.2±0.4) ％,(8.3±0.6) ％,(8.6±0.5) ％ and 0,respectively.The binding ratio of 131I-K237 and LNCaP significantly declined with the increased dose of unlabeled K237 (t=4.71,P＜0.01).The apoptosis of LNCaP cells cultured with 131I-K237 was observed.Typical DNA ladder was found by DNA gel electrophoresis.The apoptotic rates of 5,10,15 kBq131I-K237 groups were (34.1±2.9)％,(37.3±3.4)％ and (41.7±3.6)％,respectively; whereas those of unlabeled K237 groups and blank control group were (10.8±1.0) ％,(12.5±2.1) ％,(13.1±2.4) ％ and (2.9±0.3) ％,respectively.There were significant differences of apoptotic rate among groups (F=76.31,P＜0.05).The difference among 5,10,15 kBq 131I-K237 groups was statistically significant (t=3.09,3.27,4.52,all P＜0.05).Conclusion 131I-K237 can bind to LNCaP cells with highly affinity and has significant apoptosis-inducing efficacy on the prostate cancer cell line.
