Objective To investigate the clinical efficacy of acupoint catgut embedding in treating patients with early-stage type 2 diabetes.Methods Two hundred and forty patients with early-stage type 2 diabetes were randomly allocated to treatment and control groups, 120 cases each. The control group received diet control and kinesitherapy and the treatment group, acupoint catgut embedding in addition. Fasting plasma glucose (FPG), 2-h postprandial blood glucose (2hPG), glycosylated hemoglobin (GHB) and body mass index (BMI) were measured in the two groups before and after treatment and the clinical therapeutic effects were compared between the two groups.Results There were statistically significant post-treatment differences in FPG, 2hPG and GHB between the two groups (P<0.05). There was a significant difference in comparing FPG and GHB between the two groups after intervention (P<0.05).The total efficacy rate was 98.3% in the treatment group and 85.0% in the control group; there was a statistically significant difference between the two groups (P<0.05).Conclusions Acupoint catgut embedding can improve glucose tolerance and reduce the incidence of diabetes in patients with early-stage type 2 diabetes.

Thyroid function [triiodothyronine(T3), thyroxine(T4), free T3(FT3), free T4(FT4),and thyroid stimulating hormone (TSH) ] were tested by radioimmunoassay in 56 depressive patients with attempted suicide, 85 patients without suicide attempt and 40 healthy subjects (controls).The serum levels of T3 and FT3 in the patients with attempted suicide were lower than those in the patients without suicide attempt and the controls ( F = 4.937 and 5.01 1, both P ＜ 0.05 ).The lower serum levels of T3 and FT3might be the risk factor of suicide in depressive patients.

Objective To explore the characteristics of both clinical symptoms and thyroid function between depressive patients with and without attempted suicide behavior. Methods Depressive patients were divided into two groups. The first group was composed of patients with attempted suicide behavior (n = 56) and the second group without attempted suicide behavior ( n = 85 ). Thyroid function (FT3, FT4 )were determined by radioimmunoassay method. The patients were evaluated by symptom checklist 90 (SCL90). Results The score of depressive factor in the group with attempted suicide [(2. 90 ± 1. 01 ) score]was higher than that of the group without attempted suicide [(2.51±0.77) score] ( ( t =2. 127, P =0. 036). The serum level of FT3 in the group with attempted suicide [(3.92 ±0. 52) pmol/L] was lower than that of the group without attempted suicide[(4.18 ±0.71) pmol/L] ( t =-2.219, P =0.028).Conclusions There were certain characteristics on clinical symptoms of depressive patients with attempted suicide. The low serum levels of FT3 might play an important role in the risk of suicide in depressive patients.

Objective To investigate the performances and characteristics of femoro-acetabular impingement (FAI)on MSCT. Methods Hips jointed MSCT scans of 109 cases (as case group)and the other 120 cases (as control group)were analyzed retrospec-tively,to analyze the anatomy and osseous abnomality of FAI.Alpha angle,offset,CE angle were measured.The data were tested by using t test and ANOVA test.Results There were 57 cases of osseous protuberance at the femoral head and neck joint,26 cases of the offset reduction,17 cases of over-coverage acetabulum,41 cases of over-deep acetabulum,20 cases of acetabular retroversion,57 cases of subcortical cystic degeneration at the femoral head and neck joint and 22 cases of subchondral cystic degeneration at the ace-tabulum margin.Significant statistical differences were found between case group and control group in alpha angle value,offset and CE angle (P<0.05).Multiple comparisons demonstrated that except results between the value of alpha angle of Cam-type and Mixed-type(P=0.071),Pincer-type and the control group(P=0.083)with no statistical significance,the differences between any other two groups reached statistical significance (P<0.05).Multiple comparisons demonstrated that except result between the value of offset of Cam-type and Mixed-type(P=0.561)with no statistical significance,the differences between any other two groups reached statistical significance (P<0.05).Multiple comparisons demonstrate that except results between the value of CE angle Pin-cer-type and Mixed-type (P=0.444),Cam-type and the control group (P=0.236)with no statistical significance,the differences be-tween any other two groups reached statistical significance (P<0.05).Conclusion Different type of FAI has its unique anatomical features.Alpha angle,offsetand CE angle for the diagnosis of FAI have important reference values.

Objective To find a better method to reconstruct total ear in one stage. Methods In the procedure, a compound framework was formed, in which Medpor acted as ear framework and homogenous rib cartilage as helix-framework after being sculptured, then they were vamped together. The formed framework was covered with adjacent skin flap and homogenous skin graft after it had been covered with superficial temporal fascia flap. Results From January 2001 to Augest 2003, 8 cases of congenital microtia or antotia were treated in this way, and all of them obtained satisfactory appearance in auricle. Conclusion The reconstructed ear has a delicate structure and good appearance, and looks and feels as a real one by this new procedure.

OBJECTIVE:To evaluate the bioequiavailability of two kinds of loratadine tabletes in Chinese healthy volunteers.METHODS:A single oral dose 40 mg of two loratadine preparations(reference and test preparations)was given to 20 volunteers(whom were divided into two groups)in a randomized cross-over study.The concentration of loratadine in plasma was determined by solid phase extraction-HPLC.RESULTS:The main pharmacokinetic parameters of reference and test preparations were as follows:Cmax were(17.00?3.90)and(18.41?2.58)?g?L-1;tmax were(1.06?0.25)and(0.93?0.20)h;t1/2Ke were(1.34?0.38)and(1.08?0.38)h;AUC0～∞ were(37.41?17.38)and(36.38?16.73)?g?h?L-1;AUC0～8 were(35.11?15.72)and(34.76?15.34)?g?h?L-1,respectively.The relative bioavailability of the test preparation was(99.0?18.7)% as against the reference preparation,and no significant differences was noted for the two formulations in ANOVA and two-one side t test.CONCLUSION:The two formulations were bioequivalent.

The threat of cancer to human being' s health is definite.In order to find more effective cures,experts has always taking the mechanism of tumorigenesis as a research foucus and hot spot.As everyone knows,the basic biological behaviors of malignant cells have changed a lot,such as cell proliferation,apoptosis,and so on,and the causes are related to the aberrant methylation reaction occurred in these cells.Researchers have found out that DNA methylation in tumor tissues were obviously different from that in normal tissues,with the charateristics of extensive hypomethylation and localized hypermethylation.To identify the effect of abnormal methylation reaction in the evolution and progression of tumor,this article is aiming to overview those previously researches about the abnormal methylation reaction in tumor cell and its effect on cell growth.

Intrahepatic cholangiocarcinoma,which occurrence and development involved kinds of cells and genes changes,is a vital part of the primary carcinoma of liver.The cellular origin may includes bile duct epithelial cells,hepatic stem cells and hepatic cells.The macroscopic type may includes:nass-forming types,periductal infiltrating types,intraductal growth types.The fact was revealed that different macroscopic type of intrahepatic cholangiocarcinoma has different clinical features,outcomes and prognosis.The author reviewed recently published studies covering various aspects of intrahepatic cholangiocarcinoma,focusing especially on the macroscopic subtypes and related cell features,to discover the relaticn between macroscopic type and cellular origin of intrahepatic cholangiocarcinoma and better understand the pathogenesis of intrahepatic cholangiocarcinoma.

METHODS:Referring to the expert advice and guideline of clinical application of rhG-CSF at home and abroad,DUE criteria on rhG-CSF for cancer patients was established;questionnaire was designed,and the medical re-cords of rhG-CSF in a third grade class A hospital was evaluated. RESULTS:The DUE criterion on rhG-CSF for cancer patients included 3 parts,such as drug indications,the course of medication and medication results,14 items in total. Through the imple-mentation of DUE,retrospective evaluation of 220 medical records showed that the application of rhG-CSF was up to the stan-dard in respects of drug indications,no contraindication,routine blood test and drug interaction monitoring at least twice every week,there still was irrational phenomenon. CONCLUSIONS:The established DUE criterion on rhG-CSF for cancer patients is with the characteristics of definite content,target and paracticabilitg,which can provide reference for the work development of clinical pharmacists.

Total body pan & scan radiotherapeutic instrument is a special bed whose heave and the vertical slide of its bedboard are controlled by the computer. The maximum vertical travel is about 2.3 meters. To distribute equal middle plane dose in the patient's body during scanning, the doctor divides the body into four segments and gives them different lengths and velocities as required. The instrument can travel as set automatically. The reliable interlock system is involved for the maximum safety. A serial of tests prove that the instrument runs stably and the dose distribution is very uniform.
