Aim To establish and evaluate Sprague-Dawley (SD) rats model with yang-deficiency and constipation at the direction of traditional Chinese medicine theories. Methods Rats model with yang-deficiency and constipation were induced by orally administration of white vinegar and active carbon-ice water. Changes of model rats in common biological characteristic, the number and time of excretion stool, colonic electromyography, gastrointestinal hormones and intestinal neurotransmitters were observed. Results Compared to the control group: changes of the model group in common biological characteristic including abdominal distension, puffed and withered hair, sluggish response, falling body weight, black and dry stool; Excretion time of the first granule stool became longer; Number of excretion stool within six hours became shorter; Intestine pushing rate decreased, and secretion of gastrointestinal hormones and intestinal neurotransmitters disordered, etc. After being treated with Tongbianling, the syndrome and indexes of model rats markedly improved. After 6 days′ resume, the model group in the experiment of excreting stool had markedly signification in comparison with the control group. Conclusion SD rats model with yang-deficiency and constipation could be stably established by administering white vinegar and active carbon-ice water.

Deafness is a seriously disabling disease affecting the quality of human life and genetic fac-tors account for a large proportion in the pathogenesis of newborn deafness.With the development of genomics technology,molecular genetics of hearing loss has become a cutting-edge field under investigation in otology. Molecular diagnostic technique plays an important role in exploring the pathogenesis,assisting clinical diagnosis and the prenatal diagnosis.In this review,we introduce the common pathogenic gene mutations and the diagnosis of non-syndromic inherited hearing impairment.

Glucose-6-phosphatedehydrogenase( G6PD) is the main regulatory enzyme of pentose-phos-phate pathway,which plays an important role in maintaining the balance of cell energy and redox reactions in the cell. G6PD deficiency is the most common hereditary erythrocyte enzyme deficiency disease. There are no effective treatments for the disease. Currently,the key of control and treatment is to make a definitive diagnosis in time and keep away from related risk factors of the disease. At present,the main clinical diagnostic method is the detection of G6PD enzyme activity,but it is limited in accuracy of detecting the heterozygote females. It has already been confirmed at home and abroad that G6PD heterozygote is a risk factor of neonatal hyperbilirubi-nemia. Thus,the detection method of different genotypes of G6PD deficiency at the same time is urgently needed in clinical diagnosis. This paper reviews on recent research progress of the G6PD deficiency disease.

Objective To study the effects of salt restriction on blood pressure in hypertensive patients with chronic kidney disease(CKD).Methods From July to December,2006,26 hypertensive CKD patients with 24 h urinary sodium excretion(UNa)over 100 mmol/d were enrolled and received dietary education and sodium spoon.Their BP level,blood/urine electrolytes,serum creatinine and amount of urinary protein were measured before-and after-8 weeks.Anti-hypertension therapy kept unchanged during the observation period and those with UNa decreased less than 10% at the end of observation were considered as salt restriction failure.Results Eighteen patients succeeded with a reduction of UNa from(243.8?71.2)mmol/d to(135.0?49.1)mmol/d(P

Objective To retrospectively analyze the result of hemoglobin(Hb)test by using full-automatic Hb electrophoresis and evaluate the its significance in hemoglobinopathy.Methods The data of patients who underwent Hb electrophoresis test and regular blood tests in the hospital from January 2011 to December 2013 were included in the study.The test results were recorded including mean corpuscular volume(MCV),mean corpuscular hemoglobin(MCH)and results of Hb electrophoresis test.Final diag-nosis were made for suspected patients by using genetic testing,then disease detection rates and gene coincidence rates and constitu-ent ratios were calculated.Results 12 898 cases were included in the study,after statistical analysis the MCV was(85.32±13.61) fL,MCH was(29.87±6.44)pg.By using automatic hemoglobin electrophoresis,1 315 cases were found to be positive,in which 568 were male,747 were female,the detection rate was 10.19%.In the 1 315 patients,there were 761 cases suspectedα-thalassemia,ac-counted for 5.90%.There were 495 cases of suspectedβ-thalassemia,accounted for 3.84%,11 patients with HbJ(0.08%),15 pa-tients with HbK(0.12%),9 patients with HbG(0.07%),3 patients with HbD(0.02%),21 patients with HbE(0.16%).The sus-pected case′s final diagnosis were made by using genetic testing,α-thalassemia gene′s coincidence rate was 80.55%,β-thalassemia gene′s coincidence rate was 96.77%.Conclusion Automatic hemoglobin electrophoresis detection is of great significance for the di-agnosis of hemoglobinopathy.

Human enterovirus 71 (HEV71) is a major causative agent of hand,foot and mouth disease.Children infection with HEV71 can lead to series of neurological complications including aseptic meningitis,cerebral ataxia and even fatal outcomes.During recent decades,epidemic of hand,foot and mouth disease have occurred in many countries and regions in the world,which has become a major public health problem for children's health.There are no specific antiviral drugs for HEV71 infection,so it is necessary to develop safe and effective vaccine.In recent years,the research on HEV71 vaccine has made a breakthrough,and this article reviews the research progress of the vaccine.

Objective To synthesize 99Tcm labeled VEGF fragment (VEGF125-136) and evaluate its biodistribution and imaging in the nude mice bearing human osteosarcoma,in order to find a probe to improve the early diagnosis and targeted therapy of osteosarcoma.Methods VEGF125-136 was synthesized by conventional solid phase synthesis method,and directly coupled with MAG3 to form MAG3-VEGF125-136,then MAG3-VEGF125-136 was labeled with 99Tcm.The osteosarcoma bearing nude mice were randomly divided into four groups by random number table and studied for 99Tcm-MAG3-VEGF125-136 distribution at 0.5,1,2,4 h,respectively.The other 10 osteosarcoma bearing nude mices were divided into the experimental group and competitive inhibition group,and underwent radionuclide imaging.The T/NT ratio was calculated.Data were analyzed using two-sample t test.Results The radioactive labeling rate was greater than 95％,radiochemical purity was still greater than 85％ after 12 h in room temperature.The 99Tcm-MAG3-VEGF125-136 was cleared fast in blood and mainly excreted through the kidneys and liver.Tumor uptake of 99Tcm-MAG3-VEGF125-136 was highest at 1 h with (0.28±0.02) ％ID/g.The T/NT ratios of experimental group at 0.5,1,2,4 h were 1.07±0.10,3.10±0.19,2.63±0.14,1.90±0.09,respectively.In competitive inhibition group,no obvious radioactivity concentration was observed in tumors.The T/NT ratios were 0.99± 0.05,1.06± 0.06,0.98±0.03,0.97±0.03 at 0.5,1,2,4 h respectively.The T/NT ratios were significantly different between the two groups at 1,2,4 h (t=22.52,26.36 and 22.31,all P＜0.05),but no significant difference was observed at 0.5 h (t =1.44,P＞0.05).Conclusion 99Tcm-MAG3-VEGF125-136 has high labeling efficacy,good stability and high specificity to osteosarcoma.It can be used as an agent for early diagnosis and therapy monitoring in osteosarcoma.
