Protein arginine methyltransferase (PRMT) can methylate a variety of proteins,including histones and non-histones,affecting a variety of cellular processes such as transcription,RNA splicing,DNA repair,and cell cycle control.The activity of PRMT is affected by a variety of regulatory mechanisms,and its abnormal expression plays an important role in the development of the diseases,especially in tumors such as breast cancer and leukemia.PRMT has a unique value in the diagnosis or treatment of tumors.With the further exploration of PRMT methylation mechanism,PRMT selective inhibitors have made some progress.PRMT-specific inhibitors are expected to be targeted drugs for the treatment of tumors.

Objective To study the correlations between bone fracture types and healing time in patients with osteofluorosis. Methods Thirty-seven patients with osteefluorosis and long tubular bone fracture were diagnosed in accordance with radiogram retrospectively. The fractures were divided into two groups: sclerotic and osteoporotic. Twenty four fractured patients with non osteofluorosis were included in the study as controls. All of the patients had operation(open reduction and nickelclad internal fixation). Fracture healing in patients with sclerotic and osteoporotic groups was compared with the control group after operation. Results There were notable differenees(F=4.30,P< 0.05) in term of fracture healing time among the three groups [sclerotic group:(18.4±5.3)weeks; osteoporotic group: (24.5±5.1)weeks; control group: (17.6±3.8)weeks]. Notably, there were significant differences between the osteoporotic and control groups(q=2.34,P<0.05), and between sclerotic and osteoporotic gronps(q=2.51, P<0.05). The healing time of the osteoporotic group was longer than that of sclerotic group. The constituent ratios of fracture healing in sclerotic, osteoporotic and control groups were 73.1% (19/26) ,54.5% (6/11),75.0% (18/24) respectively, and the differences among the three groups were statistically significant(X2=3.67,P<0.05). The healing rate of the osteoporotic group was lower than that of sclerotic and control groups(X2=3.12, 3.36, all P< 0.05). The constituent ratios of healing in the sclerotic, osteoporotic and control groups were 26.9% (7/26),45.5% (5/11),25.0%(6/24), respectively, and there differences among the three groups were statistically significant (X2=4.07 ,P<0.05). The delayed healing rate of the osteoperotic group was higher than those of the sclerotic and control groups(X2= 3.87,3.95, all P<0.05). Conclusions Fracture healing time of osteoporotic osteofluorosis after fracture is longer than normal, and the cause might be the loss of bone mass.

Objective To investigate the risk factors of cerebral infarction in elderly patients with type 2 diabetes mellitus.Methods Elderly patients with type 2 diabetes complicated with cerebral infarction from August 2014 to March 2016 in our hospital were selected as observation group of 70 cases, elderly patients with type 2 diabetes alone of 70 cases as control group.The related indicators were compared between two groups, then the indicators with statistical difference were included into the multiple Logistic aggression analysis.Results There were significant difference between two groups of waist to hip ratio (WHR), body mass index (BMI), fasting blood glucose (FBG), 2h postprandial blood glucose (2h PBG), fasting insulin (FINS), glycosylated hemoglobin (HbA1C), triglyceride (TG) and low density lipoprotein cholesterol (LDL-C).The multiple Logistic aggression analysis showed BMI,TG,LDL-C,FINS,2hPBG and WHR were risk factors in elderly type 2 diabetes mellitus complicated with cerebral infarction. Conclusion There are many risk factors in elderly patients with type 2 diabetes complicated with cerebral infarction, higher blood sugar, higher blood lipid and higher body mass index as the independent risk factors, which should be payed attention to and prevent the occurrence of cerebral infarction.

Objective To analyze the clinical features, laboratory findings, electroencephalography (EEG) and neuroimaging of the neurosyphilis presented with parkinsonism as the principal manifestation to improve the diagnosis of neurosyphilis. Methods Eight eurosyphilis patients were from department of neurology of Hainan provincial people’s hospital from early July 2010 to December 2014. We retrospectively analyzed the clinical manifestation, laboratory exami?nations, neuroimaging examinations, diagnosis and treatment outcomes of 8 cases neurosyphilis who presented with par?kinsonism as principal manifestation. Results Myotonia and bradykinesia were principal symptoms in these 8 cases. Limb tremor, posture disorder, abnormal mental behavior and cognitive impairment occurred in some patients. Serum treponema pallidum particle agglutination (TPPA) and toluidine red untreated serum test (TRUST)were positive in 8 cas?es. Cerebrospinal fluid (CSF) protein and cell counts were elevated in all the patients. CSF-TPPA and TRUST were posi?tive in all the patients. The MRI showed that cerebral infarction in basal ganglia, cerebral atrophy in temporal lobe and hippocampus and ventricular enlargement in all the patients. EEG showed abnormal activity in all the patients. After treatment with a large dose of penicillin, clinical symptoms were obviously improved;the titer of serum and CSF TRUST decreased;and scores of UPDRS decreased in all the patients. Conclusions There is a wide variation in the clinical man?ifestation of the neurosyphilis. When patients present with Parkinsonism, we should comprehensively analyze the laborato?ry examinations, EEG and neuroimaging to rule out the possibility of neurosyphilis.

Objective To investigate the effects of output power,action time and radiofrequency(RF) needle on the cool-tip radiofrequency ablation(RFA) by experimental tools and to determine the value of ultrasonography in size evaluation of RFA zone.Methods The cool-tip RFA to fresh calf liver were monitored by ultrasound.The experiments by single electrode needle were performed with different combination of output power (80 W,120 W) and time (5 min,8 min,10 min).The cluster needle was used for assessment at 5 min with different output power(80 W,120 W).After the end of trial,the longitudinal specimens were cut open.The view and size of the ablation zone were recorded with naked eyes.The pathological changes displayed by optical microscope were recorded as well.Results The measurement of ablation zone with naked eyes showed with the ablation zone expanded with time in 80 W-power cases,but the pace of expansion slowed down,but in 120 W-power cases,expansion of the ablation zone was not obvious; the ablation zone in 120 W-power was bigger than that in 80 W-power at 5 min,their difference decreased with time,and the ablation zones were similar at 10 min.The cluster needle can produce ablation zone with lesser aspect ratio than that of single electrode needle,consequently similar to circle.Ultrasonic measurement of the ablation zone had real discrepancy.Most of longitudinal diameters were greater than the real ones,while in large ablation lesions,vertical diameters were often less than the real ones.Under optical microscope,no change could be found in shape and structure of the cells in ablation zone.Conclusion The output power and performing time have impact on ablation.The high-power output increased heat production as well as reduction of heat conduction.Compared with single electrode needle,the cluster needle produced ablation zone closer to real hepatic tumor,thus has more reliable effect to small hepatocellular carcinoma with diameter around 2 cm.The ultrasond has a great significance in RFA guidance,but it could not accurately define the border of ablation zone.

In view of the evaluation of fundus image segmentation, a new evaluation method was proposed to make up insufficiency of the traditional evaluation method which only considers the overlap of pixels and neglects topology structure of the retinal vessel. Mathematical morphology and thinning algorithm were used to obtain the retinal vascular topology structure. Then three features of retinal vessel, including mutual information, correlation coefficient and ratio of nodes, were calculated. The features of the thinned images taken as topology structure of blood vessel were used to evaluate retinal image segmentation. The manually-labeled images and their eroded ones of STARE database were used in the experiment. The result showed that these features, including mutual information, correlation coefficient and ratio of nodes, could be used to evaluate the segmentation quality of retinal vessel on fundus image through topology structure, and the algorithm was simple. The method is of significance to the supplement of traditional segmentation evaluation of retinal vessel on fundus image.

Endophytic fungi were isolated from Macleaya cordata growing in Dabie Mountain by agar-block method, and then the endophytic fungi were grouped into different types based on their morphological characteristics, and thin layer chromatography (TLC) and high performance liquid chromatography (HPLC) were employed to determine whether the metabolic substances contained sanguinarine or not, and then preliminarily identified by morphological method. The results showed that the leaves hosted the largest number of endophytes (96 isolates) followed by the stems (57 isolates) and finally the roots (28 isolates), respectively. Based on morphological characteristics the endophytic fungi were grouped into 26 types in our study. TLC and HPLC results showed that there was sanguinarine in the metabolic substances of BLH 51 strain. According to the morphological characteristic, the BLH 51 strain was identified as Fusarium proliferatum. All these indicated that the medicinal plant M. cordata harbors abundant endophytes, which could be a new source for the search of active secondary metabolites.
