Magnetic resonance imaging (MRI) is now an important diagnostic technology in determining brain structure injury. It has important meaning for determining the pathological type of CP, MRI findings in CP showed a good correlation with CP type, gestational age, etiology and injury time. In this article, the authors reviewed the advance in research on relationship between changes in MRI and gestational age, etiology and injury time.

Objective To synthesize soybean isoflavones, and their 7-alkaline analogues and to evaluate their uterotrophic activities and anti-uterotrophic activities preliminarily. Methods The target molecules were synthesized by multi-step from resorcinol and p-substituted phenylacetic acid as the starting material. Their uterotrophic activities and anti-uterotrophic activities were evaluated by female mouse at the concentration of 1.1?10 -2 ?mol/ml and 1.85?10 -3 ?mol/ml. Results Twenty-two compounds were synthesized, among which 4 intermediates and 12 isoflavones are new compounds. Conclusion All the target molecules except for 6a show weak uterotrophic activities and high anti-uterotrophic activities.

The treatment effect of primary and metastatic hepatic carcinoma after local intervention?al therapy is closely related to the prognosis of patients. Traditional imaging modalities such as CT, MRI and ultrasound can only provide anatomical information in monitoring treatment response. In recent years, PET/CT has been widely used in monitoring treatment response for tumors. Many studies have compared the effi?cacy of PET/CT with that of traditional imaging modalities in monitoring the response of primary and meta?static hepatic carcinoma after interventional therapy. This review summarizes recent progress in this field.

The occurrence of epilepstic seizures in patients with cerebral palsy (CP) remains a serious event and is very disruptive for children who already suffered from orther disabilties. Data from population-based studies or neurodevelopmental clinic studies showed that 8%～62% of patients with CP suffer from epilepsy. The incidence is highest in spastic tetraplegia and hemiplegia. Half of the patients were onset within the first year of age. Children with tetraplegia CP tended to have an earlier onset of epilepsy than chlidren with other CP types. Partial seizures were the most common seizure types, followed by infantile spasms and Lennox-Gastaut syndrome. Low birth weight, neonatal seizures, family history of epilepsy, lower intelligence and grey matter damage were found to be related to significantly increased risk of epilepsy. Epilepsy in children wih CP usually had poor outcome, half of them were intractable and needed polytherapy. Only 37%～65.2% of patients became seizure-free.

Objective To investigate the technical feasibility and oncological safety of EPMR for early esophageal cancer and precancerous lesions. Methods Clinicopathological data, procedure quality and complications of 70 patients with early esophageal cancer or precancerous lesions were retrospectively ana?lysed. The technical safety and feasibility were assessed, and the complications were investigated through postoperative surveillance. The results were compared with published data from two high?quality meta?analysis studies on ESD. Results In a total of 70 patients who underwent EPMR, 35?7%( 25/70) were diagnosed as having early esophageal cancer and 64?3%( 45/70) atypical hyperplasia. And tumor size greater than 2 cm was 78?6%(55/70). The mean EPMR time was(28?31±9?49) minutes. The R0 resection rate of EPMR was 88?6%(62/70) and no perforation occurred. The bleeding rate was 21?4%(15/70). The esoph?ageal stricture rate was 1?4%( 1/70) . The recurrence rate was 2?9%( 2/70) . Compared with published ESD data from the two studies, EPMR showed shorter procedure time, lower curative rate and lower rates of stric?ture and perforation, but slightly higher rates of bleeding and recurrence. Conclusion Both EPMR and ESD are feasible and effective for early esophageal cancer and precancerous lesions. The curative results of EPMR are similar to ESD, with shorter procedure time, but higher bleeding and recurrence rates.

Objective To study the HPLC fingerprints of isoflavones from different medicinal plants of G.max and establish a sensitive and specific method for controlling the quality of the soybean isoflavone.Methods The gradient elution mode was applied in chromatographic separation.A C_(18) column(250 mm?4.6 mm,5 ?m) was used with the mobile phase: ice acetic acid water solution(pH value 3.2)-methanol,flow rate: 0.6 mL/min,detecting wavelength: 261 nm,and the column temperature: room temperature.All 25 samples collected from different species were determined.The clustering analysis and the software of similarity analysis were applied for datum analysis.Results This method had a good repeatability and reproducibility.The ratio of peaks′ area from distinct samples were different.Conclusion The method can show the difference of chemical compositions among species completely and can be used as a quality control method for soybean.

The progressive injury of retinal ganglion cells ( RGCs) is a common occurrence in several eye diseases, which ultimately may lead to irreversible blindness. Currently, there are still no effective or ideal treatments for it in practice, however some recent studies show that stem cell transplantation may provide a promising new idea for neuroprotection and replacement of retinal ganglion cells. This paper will review the research progress of stem cell transplantation-based treatment.
