Chinese Journal of Clinical Nutrition 2009;17(1):37-40
Objective To investigate the correlation between serum levels of folic acid and vitamin B12 and depression. Methods Thirty patients with depression were selected into depression group whose Hamilton de- pression scale score exceeded 17 and/or Hamilton anxiety scale score exceeded 14. Meanwhile, 30 subjects with- out clinically significant depression were selected into control group. Their serum levels of folic acid and vitamin B12 were determined. Zung Self-rating Depression Scale and Self-rating Anxiety Scale were used to evaluate the depression and anxiety. Results The serum levels of folic acid [ (4. 06±1. 61) vs. (6. 48±2. 36) ng/ml, P < 0. 05 ] and vitamin Bl 2 [ (427.96 126. 20) t . (498.46±119.08) pg/ml, P < 0. 05 ] were significantly lower in depression group than those in control group. No correlation was found between Hamilton depression score and serum folic acid level or vitamin B12 leveL Conclusion Patients with depression have lower serum folic acid and vitamin B12 levels than those of the healthy people.
2.Progress of percutaneous balloon pulmonary valveplasty application in children with pulmonary valve stenosis
Chinese Journal of Applied Clinical Pediatrics 2017;32(1):77-80
Pulmonary valve stenosis (PS) is a relatively common congenital heart disease,and there are 2 treatment methods of surgical operation and intervention.Percutaneous balloon pulmonary valvuloplasty (PBPV) was applied successfully in children with PS for the first time by Kan.For more than 30 years,with the update of intervention equipment,improvement of operation method and accumulation of clinical experience,the application of PBPV continuously has made new progress.Most of the previous reports of the PBPV were for the immediate and short-term efficacy,while long-term follow-up data and some special types of PS review research were less.Now,combined with PBPV clinical data and long-term follow-up study in recent years,an overview of the application progress of PBPV including indications,methods,curative effect and follow-up,prevention and cure of complications and some special type of PS are provided.
3.Effects of Tsaoko-anemarrhenae Decoction on Apoptosis of the Hippocampal Neurons and it′s Gene Expression in Epileptic Rat Models.
Journal of Medical Research 2006;0(02):-
Epilepsy was arousing the attention of medical circles because of the complexity of its mechanism and the difficulty of its control.The project which used the pioneering research as the basement and was directed by the chinese medicine used the modern multidisciplinary research technologies and explored the mechanism of the brain damage in epilesy.The project′s treatment idea is different from the others,which provided a new way for seeking new medicines for treating epilepsy.The research techniques took use of the application of the behavioral methods and the electrophysiological methods creatively and the subject firstly used this way to observe it dynamically,which greatly improved the accuracy of evaluating the models and pharmacodynamics studies of the epilepsy.The research method of the project firstly observed the changing mechanism of the brain damage and the regulation of the apoptosis related genes,and even the efficiency of tsaoko-anemarrhenae decoction,which enriched the scientific intension of the decoction.The conclusions palyed a very important role in exploiting the new medicine for treating epilepsy and enriching the knowledge of the five visceras in chinese medicine.
4.Research progress in animal models of cholangiocarcinoma
Journal of Shanghai Jiaotong University(Medical Science) 2017;37(3):407-410
Cholangiocarcinoma (CCA) is a malignant neoplasm derived from cholangiocytes. The incidence of CCA is only lower than that of hepatocellular carcinoma and ranked the second in liver malignant cancers. The prognosis of CCA patients is poor and most patients will die within a few months after diagnosis. CCA is related to various risk factors, including primary sclerosing cholangitis, cirrhosis, certain chemical agents and liver fluke. Establishment of proper animal models of CCA can not only be helpful for understanding the mechanisms of incidence and development, but also lay a solid foundation for developing novel treatment strategies. Common animal models of CCA include carcinogen-induced models, implantation models, operation models, and genetically engineered models.
5.Medial Collateral Ligament Reconstruction with Semitendinosus Autograft for Medial Instability of the Knee:Report of 12 Cases
Chinese Journal of Minimally Invasive Surgery 2005;0(11):-
Objective To investigate the effect of medial collateral ligament reconstruction using semitendinosus autograft.Methods A total of 12 patients with medial collateral ligament injury received knee examinations.Among them,2 had lateral meniscus injury,and received partial resection of the lateral meniscus;2 had cruciate ligament(CL) injury(anterior CL in one and posterior CL in the other),and underwent bone-ligament-bone reconstruction.Medial collateral ligament reconstruction was performed using the semitendinosus tendon autograft ingrowth in the tibial tunnel.Results Primary healing was achieved in all the cases.In 10 of them,the stability of the knee was regained in 6-month follow-up;stress X-ray examination showed that the medial joint space was smaller than the contralateral one by less than 5 mm,and the position of the interference screw was optimal.Of the 12 patients,11 achieved an active knee flexion between 0? and 120?,the other,who had fracture of the lateral condyle of the femur,had a flexion of 90?.Conclusions Semitendinosus autograft provides sufficient tension for medial collateral ligament reconstruction.The fixation of the knee and the closure of the joint capsule can be achieved by using the method.

Objective:To study the characteristics of the adverse reactions caused by tacrolimus and analyze the risk factors. Methods:Totally 280 cases of renal transplant recipients received standard treatment options were selected from 1997 to 2013 in Wuhan general hospital of Guangzhou military command. The tacrolimus-related adverse reactions and their risk factors were analyzed statistically. Results:Totally 39. 65% of the patients had the tacrolimus-related adverse reactions. The main adverse reactions were hematotoxicity,diabetes mellitus and hyperlipidemia. The univariate analysis showed that age,weight,BMI and treatment course were the suspected risk factors. The multivariate analysis results showed that age,BMI and treatment course were the risk factors of tacrolimus-related adverse reactions. Conclusion:The incidence of tacrolimus-related adverse reactions is relatively high,and if the patient is in advanced age,with poor nutritional status or long-term medication,the probability of adverse reactions will be increased.

Objective To offer a theory that supports the individualized tacrolimus dosage regimen by retrospectively investigating the influences of gene polymorphism and other clinical factors on tacrolimus concentration in renal transplant recipients. Methods A total of 280 renal transplant recipients were genotyped for CYP3A4?5, CYP3A4?6, CYP3A4?18B, CYP3A5?3, MDR1 1236C>T, MDR1 2677G>T/A, MDR1 3435C>T polymorphisms by PCR followed by restriction fragment length polymorphism (RFLP) analysis.PXR 6bp deletions (rs3842689) genotypes were determined by Allelic Special-Touch down PCR.Correlation between gene polymorphisms and tacrolimus concentrations was analyzed. Results The mutation frequency of CYP3A4?18B, CYP3A5?3, MDR1 1236C>T, 2677G>T/A, 3435C>T and PXR rs3842689 in the renal transplant recipients was 29.11%, 69.29%, 43.57%, 49.64%, 36.43% and 26.07%, respectively.Multiple regression analysis showed that, CYP3A5?3 and red blood cell count were associated with the value of C0/D of FK506, the best regression model was:D=C0/(-60.445 +95.777×CYP3A5 +34.938×RBC), and the equation could explain 38.8% of tacrolimus individual differences. Conclusion Gene polymorphism of CYP3A5?3 and red blood cell count may be responsible, in part, for the large interindividual variability of FK506 dose and concentration.
