Journal of Central South University(Medical Sciences) 2009;34(9):846-849
Objective To determine the concentration difference in protoporphyrin in cancerous intestine and to discuss its application in laser-induced autofluorescence diagnosis for colorectal cancer at early stage.Methods We detected the concentration of protoporphyrin Ⅸ in 30 patients with colorectal cancer and 30 control patients, as well as that in 60 cases of intestinal tissues (30 control tissues and 30 cancer tissues).Results The concentration of blood protoporphyrin Ⅸ in patients with colorectal cancer was significantly higher than that in the controls (P<0.05). Protoporphyrin Ⅸ concentration in the cancer tissue was significantly higher than that in the control tissues (P<0.05).Conclusion That the concentration of protoporphyrin in cancerous intestine becomes abnormally high may be the material basis for spectrum intensity peak of (644.3±5.7)nm in laser-induced autofluorescence diagnosis for colorectal cancer at early stage.
2. Orthogonal compatibility study on main effective parts of Yangyin Tongnao Granules based on pharmacokinetics and pharmacodynamics
Chinese Traditional and Herbal Drugs 2020;51(1):135-148
Objective: To investigate the pharmacokinetic and pharmacodynamic changes of Yangyin Tongnao Granules (YTG) in cerebral ischemia reperfusion rats after the compatibility of main effective parts (total alkaloids, total flavonoids, total saponins and total phenolic acids). Methods: By using the orthogonal design to research the main effective parts of YTG, nine different dosage ratios combinations were formed, which were used for oral administration in cerebral ischemia reperfusion rats. High performance liquid chromatography-diode array detector (HPLC-DAD) was used to determine the concentration of puerarin, ferulic acid, and ligustrazine in rat plasma at different time points. The non-compartmental model was used to fit the pharmacokinetic parameters by Drug and Statistics (DAS) 3.2.6 software. The total quantum statistical moment analysis method and comprehensive evaluation method were used to evaluate the total pharmacokinetic characteristics. Meanwhile, the content of superoxide dismutase (SOD) and catalase (CAT) were determined by enzyme-linked immunosorbent assay (ELISA) kits. Finally, the PK-PD model and the quantitative equations between drug concentration and efficacy were obtained. Results: The pharmacokinetic characteristics of puerarin, ferulic acid and ligustrazine in cerebral ischemia-reperfusion rats were different. Total statistical moment and comprehensive score study showed that different combinations had different effects on ACUT, mean retention time (MRT), and comprehensive evaluation. The effective parts inhibited the reduction of oxidation indexes such as SOD and CAT. Sigmoid-Emax models were adopted in all PK-PD models, and the fitting results had a good correlation with the measured data. The R values were more than 0.85. Conclusion: Compatibility of YTG activity parts had a certain effect on their pharmacokinetic behaviors and antioxidation in model rats. The total quantum statistical moment analysis and comprehensive evaluation method can be used to study the pharmacokinetics of multi-component traditional Chinese medicine prescriptions. PK-PD model could be used to predict and evaluate the correlation between pharmacokinetics and pharmacodynamics of traditional Chinese medicine prescriptions.

BACKGROUND:To explore the methods for secondary limb revascularization after endovascular repair is one of the most urgent research topics.
OBJECTIVE:To investigate the biological mechanism about the transplantation of autologous peripheral blood stem cel s to lead and perfect the effect of ischemic tissue for secondary revascularization.
METHODS:Forty-two patients with critical low limb ischemia were selected and treated with endovascular repair as first revascularization and transplantation of autologous peripheral blood stem cel s as secondary revascularization. The secondary revascularization was carried out at 3 months after the first blood flow remodeling. The patients receiving secondary revascularization were fol owed for 4 years.
RESULTS AND CONCLUSION:After transplantation of autologous peripheral blood stem cel s, the patients complained that the rest pain of the lower leg was relieved obviously and intermittent claudication distance was significantly lengthened. Limb salvage rate was 100%. Skin temperature index was 1.6±0.3, transcutaneous oxygen pressure was (5.00±1.26) kPa, ankle-brachium index was 0.9±0.2, photoplethysmograpy index was 0.8±0.1, saturation of blood oxygen was (79.4±20.4)%, and digital subtraction angiography score was (1.3±0.2)
points. After transplantation, local blood flow indicators of the low limbs were positively correlated to local symptom indicators of the limbs (0.6

Objective To summarize continuous veno- venous hemofiltration (CVVH) treatment of infants with complex congenital heart disease in children with acute renal failure after treatment. Methods A retrospective analysis was carried out in six cases of infants with congenital heart disease with application of CVVH. The children were given monitoring and anticoagulant treatment. The renal function, electrolytes and urine volume were compared before and after the treatment. Results The amount of urine increased, blood circulation and electrolytes remained stable in six patients 17.5-135.0 hours after CVVH. Conclusions The CVVH therapy can be applied to treat infants with congenital heart disease complicated with acute renal failure, but CVVH treatment should focus on anticoagulants and blood volume since complicated state of illness, low age, low body weight of children patients.

Background Congenital aniridia is a rare bilateral hereditary ophthalmopathy which impact panocular.Researches showed that congenital aniridia can be caused by different mutation locus of PAX6 genes,and the mutations are multifarious.Objective This study was to detect and anaiyze the mutations of a Chinese family with congenital aniridia by using targeted sequence capture sequencing and direct Sanger sequencing.Methods This study was approved by Ethic Committee of the First Affiliated Hospital of Zhengzhou University and followed Declaration of Helsinki.Written informed consent was obtained from subjects or their custodians before any related medical examination.A cross-sectional study was performed.A Chinese congenital aniridia family was included at the First Affiliated Hospital of Zhengzhou University in March,2016.All the family members received systemic medical examinations including nervous system and oral glucose tolerance test and then the ocular examinations were carried out.The periphery blood of 10 ml was collected from the members for genomic DNA extraction.Targeted sequence capture sequencing was performed on the DNA of proband to screen out the suspicious mutant locus.The mutation was verified by comparing the Sanger direct sequencing results from all family members.Results A total of 3 generations of 9 members were included in this congenital aniridia pedigree,and the Ⅰ 1 was dead without eye abnormality.Three patients (Ⅱ2 and her children Ⅲ1,Ⅲ2) and 5 normal family members were determined,showing an autosomal dominant inheritance pattern.No abnormal signs were found in nervous system and oral glucose tolerance test in the families.The reduce of visual acuity,ocular hypertension (21 mmHg),absence of biocular iris,opacification of corneal stroma,horizontal nystagmus,hapoplasia of fovea were found in all the sufferers.In addition,the ptosis of the left eye,congenital cataract of the right eye in Ⅱ 2 patient as well as biocular cataract and subluxation of lenses also were exhibited.The c.183C>A mutation of the PAX6 gene was screened out to be a possible pathogenic mutation.The result of Sanger direct sequencing in the families verified a co-segregation of this mutation with mutant phenotypes.Conclusions PAX6 gene c.183C >A,a rare mutation in Chinese population,is a virulence mutation site in this aniridia family.
