Objective To evaluate the detection and localization of obscure lower gastrointestinal bleeding by using SPECT/CT and intraoperative endoscopy. Methods Twenty-six cases of patients with obscure lower gastrointestinal bleeding were analyzed retrospectively. Results The positive detection rate of SPECT/CT was 88.5%. All 26 patients (100%) were identified the bleeding source by using intraoperative endoscopy. No recurrence was found during 1-24 months follow-up. Conclusion SPECT/CT examination should be chosen firstly for patients with obscure lower gastrointestinal bleeding in order to localize the bleeding site roughly. Intraoperative endoscopy can localize the bleeding site accurately in patients who undergoes operation.

Objective To study the applicatble value of absorbable biomedical membrane (ABMM) in thyroid operation.Methods ABMM (size 0.02 cm) was placed between trachea and the skin flap trachea and the anterior muscles of the neck, and between anterior muscles of neck and the skin flap after radical cure for thyroid cancer of thyroidectomy including one or two lobes. Results Conglutination under the incision was significantly lighter in experiment group (153 cases ) than control group (139 cases) ( P

Infectious disease is a kind of disease that can be transmitted between humans and animals. Respiratory infectious diseases are more likely to cause outbreaks through droplet transmission. Coronavirus has repeatedly caused global public health events. Initial symptoms of the infected patients were mild, and the onset of the disease was hidden, but some patients suddenly get worse in a short time, and eventually died due to multiple organ failure. Studies have found that cytokine storms caused by patients′ excessive immune response was one of the important causes of death in the infected patients.
