The target therapeutic agents of HER-2 extracellular ligand-binding domain have become the core of breast cancer research. A small peptide molecule and an anti-HER2 extracellular domain monoclonal antibody conjugated with protein toxins, radioisotopes, and chemotherapeutic drugs (immunoconjugate) can improve efficacy and reduce systemic toxicity. Vaccines based on HER-2 extracellular region should protect patients from HER-2-overexpressing breast cancer growth. In this review, studies on targeted-block therapies of the HER-2 extracellular ligand-binding domain in breast cancer were discussed to provide references for clinical applications.

Objective To reveal the relationship between the 5-HTTLPR and the Chinese Han nationality children with CA, compared the distribution of the 5-HTTLPR between the Han Chinese children with CA and healthy Han Chinese children ,and analyzed the association between the 5-HTTLPR and clinical symptoms of the Han Chinese children with CA. Methods Genomic DNAs of fifty subjects including 25 autistic children and 25 controls were extracted from blood samples. PCR amplification using Oligonucleotide primers flanking 5-HTTLPR was performed. Results ① Three kinds of alleles including the S (short) allele, the L (long) allele and the VL allele were found , and the 5-HTTLPR genotypes shown were S/S, L/L, S/L and L/VL. ② Allele frequencies did not differ significantly in patient groups in comparison with the control sample. No significant difference was identified between the observed 5-HTTLPR genotype distribution of the patient groups and control group. ③ The distribution of homozygous and heterozygous subjects between the two groups differed significantly. ④ The genotypes of the 5-HTTLPR polymorphism correlated significantly with the Body Movement Factor. ⑤ The allele frequency of healthy Han Chinese population and that of healthy Japanese population were similar. The frequency of S allele in not only autistic subjects but also healthy children in this study was considerably more than that in Caucasians and the frequency of L allele in our subjects decreased correspondingly. Conclusion ① A significant difference in the allele frequency between the Han Chinese and Caucasian populations was found. ② The genotypes of the 5-HTTLPR polymorphism correlated significantly with the Body Movement Factor of the patients. ③ The homozygote and the L allele were positively relevant to CA and they might be the risk factors of CA. The heterozygote and the S allele were negatively relevant to CA and they might be the protective factors of CA.

Objective To explore the effects of repetitive transcranial magnetic stimulation (rTMS) on cognitive ability of patients after ischemic stroke. Methods 45 patients with mild cognitive impairment (MCI) after ischemic stroke were randomly assigned into control group (n=22) and observation group (n=23). Both groups received routine drugs and cognitive training. The observation group received rTMS over the left dorsolateral prefrontal cortex (DLPFC) (5 Hz, 80% motor threshold) in addition for 4 weeks. Results The score of Montreal Cognitive Assessment (MoCA), P300 latencies and amplitudes improved after treatment in both groups (P<0.001), and were better in the observation group than in the control group (P<0.05). The MoCA score was negatively related with P300 latency (r=-0.851, P<0.05). There was no severe adverse effect during the treatment. Conclusion rTMS could improve the cognitive ability of patients with MCI after stroke, with little side effect.

Objective To test using musculoskeletal ultrasound (MSUS) to observe uncovertebral joints (UJs) and to explain the ultrasound images of UJs and their adjacent tissues,especially the vertebral artery (VA).Methods MSUS was used first with human skeletons and cadavers to localize the UJs and VA on the MSUS images with the aid of implanted needles.MSUS was then used with a patient clinically diagnosed with cervical spondylosis of the vertebral artery type (CSA) to detail the image of a normal UJ and its relationship with the adjacent tissues,especially the VA.Whether there was a lateral spur from the uncinate process (UP) was assessed to try to establish a method for measuring osteophytes.Results During the examination the patient was in supine,the neck was elevated 15cm with a pillow and was at 45 degrees of rotation to the contralateral side.The probe was placed at the medial border of the sternocleidomastoid muscle.When the longitudinal section of the common carotid artery was shown,the probe was slowly moved laterally until the VA first appeared,and then was moved up along the VA.Once the VA entered the transverse foramen,moving the probe slightly allowed the UJ behind the VA to be seen between two transverse processes.The UJ thus lies between two transverse processes,that is,between the lateral margins of two vertebral bodies and outside the intervertebral disc.The echo of the lateral border of the UP is on a straight line with the echo of the lateral margin of the vertebral body,with the VA in front of the line.It was noticed that the image of a UP with lateral osteophyte formation crossed the line and reached closer to the VA.The transverse diameter of the UJ was measured as the distance from a line cutting the lateral cortical margin of the cervical vertebra to the outer cortical margin of the lateral UP.Conclusion MSUS can clearly show the UJ and its adjacent tissues,especially the VA.It can be used to assess and measure UJs with lateral osteophyte formation.
