Type 1 diabetes mellitus(T1DM),also known as insulin dependent diabetes mellitus (IDDM), is classified as an autoimmune disease.Academia currently define it as one of the important autoimmune diseases(IAIDs).The most significant pathophysiological characteristics of T1DM are the pathological humoral and cellular autoimmune response which results in damage to pancreaticβ-cell and absolute reduction insulin.Thus, the mainstream traditional therapy for T1DM has been to chronically replenish insulin or substitutes.Nevertheless, this approach may generate a number of side effects, especially hypoglycemia reaction, hypoglycemic coma and insulin resistance.In recent years, the clinical use of methotrex-ate(MTX) as an immunity inhibitor or regulator aiming at pathogenesis of T1DM has received increasing attention and will become another significant case where an old drug is used for new purposes.The advances in research on MTX in T1DM are discussed in this paper.

Pulse wave, a research focus in both traditional Chinese medicine and Western medicine, which contains a wealth of human physiological and pathological information, has always been the concern of medical practitioners. On the basis of the review on the development of the pulse wave theory and its applications, the existing problems in this field are discussed in this paper. On the basis of the status quo of pulse wave information extraction methods and the utilization of pulse wave in traditional Chinese and Western medicine, a more in-depth study on pulse wave is proposed to make it a bridge connecting traditional Chinese medicine with Western medicine.

Carotid artery stenosis is one of the main causes of ischemic stroke. Carotid artery stenting has gradually become a mainstream treatment approach of carotid stenosis, and the in-stent restenosis is its most common late complications, which restricts the development of carotid artery stenting. This article reviews the epidemiology, imaging evaluation, pathophysiological mechanism, and prevention and treatment measures of carotid in-stent restenosis.

Objective To explore the feasibility of laparoscopic splenectomy (LS) in the management of ruptured spleen. Methods Laparoscopic splenectomy was performed in 8 cases of ruptured spleen in this hospital from August 2004 to May 2005. Results Laparoscopic splenectomy was accomplished successfully in 7 cases and a conversion to hand-assisted laparoscopic splenectomy (HALS) was needed in 1 case. The operation time was 150~200 min (mean, 180 min). The intraoperative blood loss was 600~5 500 ml (mean, 2 200 ml). There were 5 cases of type Ⅱ rupture and 3 cases of type Ⅲ rupture. The postoperative recovery was uneventful and no complications were encountered. Conclusions[WTBZ] Laparoscopic splenectomy is a safe and feasible option for the management of ruptured spleen.

Objective:To investigate the effects of the different static compressive stress on the proliferation and apoptosis of condylar chondrocytes in vitro.Methods: 0, 12, 24, 36 kPa static compressive stress were applied to the third passage of mandibular condylar chondrocytes for 1 hour respectively. The changes of proliferation and apoptosis of condylar chondrocytes were evaluated by flow cytometry analysis. Results: The index of proliferation and apoptosis of cells decreased with the magnitude value of static compressive stress except 24 kPa group. The most significant decrease of proliferative index and apoptosis index was found in 36 kPa group and 12 kPa group respectively. Conclusion: There might be some corelationships between magnitude of static compressive stress and the proliferation and apoptosis of condylar chondrocytes.

Objective:To investigate the expression of transforming growth factor-?1 (TGF-?1) in mandibular condylar chondrocytes after the condylar cartilage was stimulated by compressive stress.Methods:20 condylar cartilage samples were obtained from 10 new borne SD rats and cultured for 24 h.Then,10 samples were treated by a static compressive stress with a magnitude of 10 kPa for 1 h.Another 10 samples without stress treatment were used as the controls. At end of stress stimulation, the expression of TGF-?1 in the samples of both groups was examined by immunohistochemistry and image pattern analysis.Results:The grayscale values of TGF-?1 in perichondrium lay of stress treated and control samples were 159.21?19.84 and 174.20?14.47(P

Objective To compare the effects of Graves thyrotoxicosis patients treated by long-term use of anti-thyroid drug ( ATD) and without long-term use of ATD ,and to explore the application value and safety of ATD be-fore 131 I treatment.Methods 62 cases with Graves hyperthyroidism were divided into the two groups according to whether received the long-term ATD treatment.The curative effects,hormone level and safety were compared.Results The success rate of ATD group was 43.75%, the success rate of without ATD treatment group was 56.67%, the difference between the two groups had statistical significance (Ridit=15.152,P=0.000).The thyroid mass,FT3, FT4 ,TSH levels after treatment between two groups had no significant differences , but the difference of the highest iodine uptake rate in 24h had significant difference (t =6.954,P<0.05).The adverse reactions in ATD treated group and ATD untreated group were 7 cases(21.88%) and 3 cases(10.00%),there was statistically significant difference between the two groups(χ2 =4.563,P=0.032).Conclusion Long-term ATD therapy before 131I treatment can reduce the highest iodine uptake rate in 24h,reduce the clinical curative effect and increase adverse reaction rate .
