Contamination of foodborne pathogens is the main cause of related diseases. Escherichia coli O157:H7 (E.coli O157:H7), as a representative of pathogenic E.coli, is one of the most severe and commonly reported E.coli in the world, but there is still no effective clinical treatment against the infection. Antibiotics show effective in the early infection of E.coli O157:H7. However, their extensive use has led to drug-resistant bacteria and genes in recent years, which becomes a great threat to public health. This article reviews the research progress of E.coli O157:H7 from the prevalence of antibiotic-resistant bacteria, the resistance mechanism, and the prevention and control methods, in order to provide a reference for its prevention, early clinical treatment and related research.

Objective To investigate the methods and effects of the double foliated anterolateral thigh flap in wound repair.Methods From March 2001 to January 2007,nine patients with adjacent soft tissue defects were treated by double foliated anterolateral thigh flap.Of all patients,three patients were with perforating injury.Results All the transplanted flaps survived,except for one patient with superficial necrosis in extremities,who got healed with dressings change and anti-infective therapy.All patients were followed up,which showed that all flaps had excellent appearance,with a normal color and consistency.Conclusion The double foliated anterolateral thigh flap has the advantages of foliated anterolateral thigh flap and is an optimal method for repairing adjacent soft tissue defects.

To evaluate the clinical application of defecography in irritable bowel syndrome, 14 cases of diarrhoea predominant IBS, 12 cases of constipation predominant IBS and 10 cases of mixed patterns underwent defecography. Thirteen cases showed abnormal IBS (36 11%). The abnormal X ray features of anorectal angle and pelvic floor descent included rectocele, rectal mucosal prolapse, splanchnoptosis, perineum descent and spastic pelvic floor syndrome. Defecography is valuable in the diagnosis and treatment of irritable bowel syndrome

Objective:To describe and analyze the clinical manifestations of patients with orofacial pain of temporomandibular disorders (TMD).Methods:A retrospective study on orofacial pain was conducted for 3 425 patients diagnosed as TMD based on clinical symptoms and signs in the Department of Temporomandibular Disorders and Orofacial Pain, School of Stomatology, The Fourth Military Medical University. The patients included 1 158 males and 2 267 females with a median age of 32 years. The gender, age, course of disorders, pattern and site of pain, CT imaging diagnosis of temporomandibular joint (TMJ) were analyzed. The distribution of gender, age and disorder course interval were described. The differences in frequency of the pattern and site of pain, imaging diagnosis in different gender, age and disease course interval were compared. Chi-square test and non-parametric rank sum test were performed using software SPSS 23.0.Results:Of the 3 425 patients, 29.1% (997/3 245) had signs of joint popping, and 40.1% (1 373/3 425) had restricted opening. The pain frequency was higher in males who had disorder course less than 1 month ( P<0.01) and also in males who had open-and-close and/or lateral excursion and/or protrusion pain without tenderness or other pain without tenderness ( P<0.05). However, the pain frequency was higher in females who had tenderness ( P<0.01). The pain frequencies in those over 56 years old with tenderness combined with open-and-close and/or lateral excursion and/or protrusion pain were higher than in patients of other ages ( P<0.01). In patients with unilateral TMJ pain, the frequency in males was higher than females( P<0.01), while the frequency in females was higher in patients with unilateral TMJ pain combined with unilateral or bilateral myalgia and the frequency was higher in patients under 15 years old having bilateral TMJ pain and/or unilateral or bilateral myalgia ( P<0.05). In patients with unilateral TMJ pain, the frequency in those with disorder course≤1 month was higher than in those with other disease duration intervals ( P<0.01), while in patients with bilateral myalgia or TMJ pain plus unilateral or bilateral myalgia, the frequency in those with disorder course>3 years was higher than in those with other disease duration intervals( P<0.01). In patients with unilateral TMJ pain, the frequency was higher in those having open-and-close and/or lateral excursion and/or protrusion pain ( P<0.01). In patients with unilateral myalgia and bilateral myalgia, the frequency was higher in those having tenderness ( P<0.01). The frequency of TMJ space changes in male patients was higher than females and the frequency of hyperosteogeny and resorption in females were higher than males ( P<0.05). The frequency of TMJ space changes and developmental problems were higher in patients aged 16 to 35 years, while the frequencies of hyperosteogeny, bone resorption and cystis in those over 56 years were higher than other ages ( P<0.01). The frequency of TMJ space changes in patients with disorder course≤1 month was higher than in those with other disease duration intervals ( P<0.01), while the frequency of hyperosteogeny was higher in patients with disorder course>3 years ( P<0.01). Conclusions:The male to female ratio in the present patients with orofacial pain of TMD was about 1 to 2. Most of the patients visited hospital within half a year after the disorders occurred. The pattern and site of the orofacial pain, signs on TMJ CT images showed some distribution regularities in views of gender, age and disorder course.

OBJECTIVE: To ensure the supply of prevention materials in the tertiary public hospitals in prefecturelevel cities, and to make the process of allocating prevention materials more scientific and reasonable. METHODS: Open the green passage, simplify the procurement process, carry out emergency procurement of related materials, ensure timely delivery of prevention materials, distribute them at different levels, and strengthen the warehouse management of prevention materials. RESULTS: The scheme of emergancy supplies was constantly improved, and the supply of prevention materials was completed with good quality. CONCLUSIONS Using scientific and efficient management methods, the supply of prevention materials in medical institutions has been guaranteed, which has experience and reference significance for the prevention and control of similar public health emergencies in the future.
