1.Immunological Characteristics of Beige-Nude Mice:Research and Development
Acta Laboratorium Animalis Scientia Sinica 2009;17(6):460-464
Immunodeficient animals are animal models that are suitable for medical research. Beige-Nude mice are deficient in both T lymphocytes and natual killer (NK) cells simultaneously. The T cell activity and NK cell activity are much lower in Beige-Nude mice. They were bred for cancer research at first. Researchers have studied the immunologic characteristics of Beige-Nude mice vastly and deeply since 1970s. So this expands its application in medical research.

3.Progress in drug transporters in hepatocytes
Chinese Journal of Pharmacology and Toxicology 2014;(5):806-812
Hepatic drug transporters(HDTs),including uptake transporters and efflux transporters, play an important role in drug distribution and elimination in the liver. The influx HDTs include organic anion transporters,organic cation transporters,organic anion transporter polypeptides and Na+-tauro-cholate cotransporting polypeptide. The efflux HDTs include multidrug resistance proteins,multidrug resistance-associated proteins,breast cancer resistance protein and bile salt export pumps. Major research methods involve gene knock-out animals,isolated perfused livers,liver slices,primary hepato-cytes and transfection cells. They have been used in study of drug distribution,drug-drug interaction and drug toxicity.
4.The study of serum testosterone concentration in different aged men
Chinese Journal of Geriatrics 2003;0(08):-
Objective To study the relationship of total serum testosterone and free testosterone with the age of men. Methods A total of 136 heathy men were classified into six groups. Enzyme immunoassay was applied to measure the serum level of testosterone and free testosterone, and then the relationship between the androgen change and the age was analyzed. Results The level of testosterone of 20-, 30-, 40-, 50-, 60- and 70-78 age group were (6.208?2.275),(4.960?1.719),(5.910?3.054),(4.964?1.531) ,(3.967?2.514) and (4.146?2.497) mg/L respectively.Free testosterone concertrations were:(23.300?9.530),(22.060?12.627),(16.290?6.858),(14.782?6.851) ,(14.005?8.724) and (12.256?7.462) ng/L respectively. The level of blood testosterone decreased in 60-year age groups and the difference between 20-, 30-year old group and 60-year old group was significant (P
5.Venesection Ventouse Coordinated with Helium-neon Laser Combined with Drugs Treat Early Herpes Zoster
Journal of Zhejiang Chinese Medical University 2015;(5):396-397,398
Objective]Observe the clinical effect of early herpes zoster which were treated by venesection ventouse combined with helium-neon laser and drugs. [Methods]The control group 32 cases used Famciclovir Tablet,transfer factor capsules,mecobalamin and acyclovir cream-drug for external use. While the experimental group 32 cases used Famciclovir Tablet,transfer factor capsules,mecobalamin and acyclovir cream-drug for external use. While the experimental group besides taking above-medicine, were treated with venesection ventouse and helium-neon laser at the pathological change. [Results]The control group used to cure for an average of 13 ±2.5 days. The experimental group used to cure for an average of 9.6 ±2.4 days. There were significant differences(P<0.05). [Conclusion] Early herpes zoster treated by venesection ventouse combined with helium-neon laser and drugs, can significantly shorten the duration of symptoms, alleviate suffering, and has good clinical efficacy.
6.Efficacy of intraoperative lymphatic mapping in determination of sentinel lymph node of early stage breast cancer
Chinese Journal of Current Advances in General Surgery 1998;0(01):-
0 05).Conclusion:Intraoperative lymphatic mapping with methylene blue is easily performed in early breast cancer patients.To determine the sentinel lymph node and status of axillary lymph node metastasis by pathological examination of the stained lymph nodes,there was hight false negative rate and unacceptable rate of misdiagnosis.So,its feasibility need further evaluation.[
7.Experimental study on effect of Yizhiningshen Granules on recognition function of animal model with attention deficit hyperactivity disorder
China Journal of Traditional Chinese Medicine and Pharmacy 2005;0(10):-
Objective:To explore the effect Yizhiningshen Granules on recognition function of animal model with attention deficit hyperactivity disorder(ADHD).Methods:The treatment groups were given the high,middle and low dosage of Yishi-ningshen granules respectively,Jingling liquid was given to control group of TCM and Ritalin to control group of Eestern medicine.Recognition function was tested by Morrris Water Maze(MWM) method.Results:In model group,the course of learning delayed and the ability of learning acquisition and memory retaining decreased obviously in MWM test.Among five treated groups,compared with the Ritalin group,the course of learning decreased and the ability of learning acquisition and memory retaining improved markedly in the TCM groups(P
8.Discussion on pathomechanism hypothesis ADHD caused by growth retardation of spinal marrow
China Journal of Traditional Chinese Medicine and Pharmacy 2005;0(08):-
Chinese medicine has certain advantages in treating the disease of children ADHD which caused by brain dysfunction. According to the physiological characteristics of "kidney is often insufficient" in children, and the close relations among kidney, marrow, essence and brain, we put forward the pathomechanism hypothesis that growth retardation of spinal marrow caused ADHD, and thought that the def iciency of kidney essence, growth retardation of spinal marrow, and imbalance of yin and yang (yang superabundant and yin insufficient), are the keys of pathomechanism of ADHD. Accordingly, the tonifying kidney and replenishing essence treatment principle was established, and YiZhiNingShen granule was made which had been conf irmed effectively by clinical and experimental research.

Objective To observe the effectiveness and salty of Xiaoer Dingfeng Decoction(Decoction to stop wind in children con- vulsion)in the treatment of syndrome of primary infantile convulsion due to phlegm-heat in tonic-clonic epilepsy.Methods Totally 90 infantile patients were randomized into three groups,which were treated by Xiaoer Dingfeng Decoction,Kangxian(Capsule to treat epilepsy)and Xifeng Capsule(Capsule to calm the wind)respectively.Frequency of seizure,lasting duration,and change of electroen- cephalogram(EEG)were observed 12 months later.Results The total effective rate of Xiaoer Dingfeng Decoction group was 86. 67%,better that that of Kangxian Capsule group(P0.05). It could greatly reduce the frequency of seizure,shorten the lasting duration,and improve the EEG.Conclusion Xiaoer Dingfeng De- coctions is effective and safe for the syndrome of primary infantile convulsion due to phlegm-heat in tonic-clonic epilepsy.

Objective To explore imaging manifestations and diagnostic value of helical CT in maxillofacial fractures associated with craniocervical junction injury. Methods Helical CT findings of ten cases with maxillofacial fractures involving the craniocervical junction injury were retrospectively analyzed and compared with other imaging techniques. Results There were five cases with both fractures of the maxilla and mandible combined with zygomatic arch fractures, three with mandible fractures combined with dislocation of temporomandibular joint and three with mandible fractures combined with slight and moderate craniocerebral injuries. The combined craniocervical junction injuries included atlantoaxial rotary dislocation in six cases, occipital condyle avulsion fracture in two and occipitocervical subluxation in two. Conclusions Maxillofacial fractures combined with the occipitocervical junction injuries are usually ligament injuries, with radiologic characteristics of avulsion fracture, occipitocervical subluxation and atlantoaxial rotary dislocation. Helical CT is a satisfactory mode for diagnosis of such fractures. More attention should be paid to mark of anatomical relation of craniocervical junction to avoid missed diagnosis.
