Two unusual cases of coexistence of Hashimoto′s thyroiditis and subacute thyroiditis were reported. The diagnosis was based on the comprehensive analysis of clinical symptoms, laboratory data and histological findings. If patients with confirmed evidence of subacute thyroiditis were accompanied with markedly and persistently elevated titers of thyroid autoantibodies, coexistence of both diseases should be suspected.

On the basis of Shay's ulcer model, we have studied the effects of food re. striction time on the experimental gastric ulcer in rats. The results indicat that each restricted group forms gastric ulcer after ligation of pylorus 18 hr. There are a postive correlation between the restricted time and the severity of gastric ulcer, and a negative correlation between the severity of gastric ulcer and the amount of gastric acid secretion. We suggested that Shay's ulcer model does not belong to peptic ulcer, but belonges to one of the stress ulcers. The restricted time may play an important role in the mechanism for this ulcer model.

This article reviews and summarizes recent years’ literature on the correlation of substance P with meridians and acupoints in order to provide a theoretical basis for the mechanism of acupuncture effect.

Objective The aim of this investigation is to explore the effects of hypoxia on the biological activity of endothelial progenitor cells(EPC)and to improve the efficacy of EPC transplantation.Methods Rat bone marrow derived EPC were isolated and cultured either under normoxic or hypoxic conditions.The proliferation,migration and angiogenic ability of EPC were observed.Results In hypoxic group,the number of attached cells per high power field(hpf)was significantly more than that in normoxic group (91.0?8.0)vs(42.5?5.3),P

It is now clear that both endogenous and exogenous sources of nitric oxide(NO) exert important modulatory effects on cardiac mitochondrial function.There is also growing evidence that NO can be produced within the mitochondria themselves.NO can influence respiratory activity,both through direct effects on the respiratory chain or indirectly via modulation of mitochondrial calcium accumulation.At pathological concentrations,NO causes irreversible alterations in respiratory function and also interacts with reactive oxygen species(ROS) to form reactive nitrogen species(RNS),which may further impair mitochondrial respiration and even lead to open the mitochondrial permeability transition pore and induce cell death.Diabetes,aging,myocardial ischemia,and heart failure are all associated with altered ROS generation,which can alter the delicate regulatory balance of effects of NO in the mitochondria.

The urinary concentration of pseudouridine, primarily a degradation product of transfer ribonucleic acid, was determined by high-performance liquid chromatography in 84 patients with lung cancer, 22 patients with pulmonary infectious diseases and 69 healthy controls. The concentration of pseudouridine in the patient with lung cancer (33.46 ? 9.94nmol/ ?mol) was significantly higher than that in the paients with pulmonary infectious diseases (26.25 ? 4.17nmol/ ?mol, P

Objective To diagnose Chinese autosomal dominant polycystic kidney disease (ADPKD) rapidly by detecting microsatellite SM7. Methods Microsatellite SM7 was amplified by modified PCR in two temperatures. Gene linkage analysis was performed. Rusults DNA analysis predicted 9 asymptomatic members as PKD1 gene carriers. Conclusion The presymptomatic gene diagnosis could be done rapidly by detecting microsatellite SM7 with modified PCR amplification in two temperatures.

Objective To explore the main reason of secondary barrenness resulted from drug miscarriage before childbearing. Methods Gynecologic examination was performed in 156 patients with secondary barrenness after drug miscarriage. Uterus neck and vaginal smear examination, mycoplasma and chlamydozoon detection, and hysterosalpingograghy were performed in the same time. Results 101 patients (101/156,64.74%) had genital duct inflammation,61 patients (61/156,39.1%) had various degrees of tubal obstruction. Conclusion The main reason of secondary barrenness after drug miscarriage was the tubal obstruction resulted from inflammation, especially chlamydozoon and mycoplasma infection. Drug miscarriage was not so safe before childbearing.
