The intestine microbiota and the host interacts with each other.Resently,the association and causality between gut microbiota and cardiovascular diseases have been well studied.Some underlying mechanisms,especially metabolic pathways are known, including the role of trimethylamine N-oxide in the pathogenesis of atherosclerotic heart disease and heart failure and that of short chain fatty acids and their receptors in blood pressure regulation.

In order to enhance the survival rate of abalone larvae, antibiotic susceptibility tests were performed on the bacteria isolated from whitened postlarvae, biofilm and the pond water of abalone (Haliotis diversicolor superteta) and proven to be virulent pathogens by challenge tests. API tests indicated that the isolates were mainly comprised of Vibrio alginolyticus, vibrio cholerae, Vibrio parahaemolyticus, the total Vibrio number of which was seventeen and made up about 50% of the total population. Among vibrios, Vibrio alginolyticus was the dominant strain (11 isolates) and made up 70%. Antibiotic susceptibility tests demonstrated that while majority isolates exhibited relatively high sensitivities toward streptomycin, erythromycin and gentamycin, they nevertheless displayed resistance to tetracycline and novobiocin. Results clearly indicated that streptomycin, erythromycin and gentamycin could be potentially used to suppress vibrio growth and hence improve abalone postlarval survival rate.

Objective To investigate the clinical characteristics on diagnosis and treatment of renal tubercu- losis.Methods Clinical data of 82 patients with renal tuberculosis were retrospectively reviewed.Results All of the 18 cases who received medication recovered completely.64 cases undergoing surgery were pathologically diagnosed to have renal tuberculosis,of which 2 cases developed ureteral stump syndrome.Conclusion Urine PCR-TB-DNA re- mained the primary diagnostic method before operation.Computed tomography(CT)and magnetic resonance urogra- phy(MRU)could be used in diagnosis of renal tuberculosis.When the non-functioning kidney was resected,per- inephrit fat and the involved ureter should be concomitantly resected as much as possible.

[Objective] Aneurysmal bone cyst of the ealeaneus is an uncommon entity. The purpose of the report is to describe aneurysmal bone cyst of the ealcaneus seen in a child.[ Methods] The clinical, radiological and histopathologic findings of a boy with aneurysmal bone cyst of the calcaneus were retrospectively analyzed with reference to literature. [ Results ]The tumor mainly involved the right calcaneus. He was treated successfully after the curettage and bone grafting. Histopathological examination revealed an aneurysmal bone cyst of the right calcaneus. He is now disease-free for 2 years, and no sign of recurrence was found. [ Conclusion] Aneurysmal bone cyst of the calcaneus is an uncommon entiy. To simple aneurysmal bone cyst,curettage and bone grafting are effective therapic method.

Objective To evaluate the matching degree of donor's and receptor's tissue typing and analyze the relationship between the degree and the early survival of cardiac transplantation with donor's and receptor's tissue typing of 9 cases of cardiac transplantation. Methods In accordance with the international standard, donor's and receptor's blood type, HLA antibody, lymphocytotoxicity and panel reactive antibody were determined in 9 cases of cardiac transplantation, and the donor's and receptor's matching degree evaluated by methods of amino acid triplets and cross-reactive group. Results Of 9 cases, 6 survived while 3 died. Of the 3 dead cases, 2 came respectively from the two best comprehensively evaluated matching cases and two worst, and postoperative biopsy showed that there was no rejection in either survival cases or the dead cases. Conclusion With the effective immunosuppressant, the HLA typing doesn't affect the early survival.

Objective To evaluate the application of the LMA CTrach for airway management during cervical spine surgery.Methods A total of 80 patients received cervical spine surgery under general anesthesia. During the operation, the LMA CTrach was used for ventilation and insertion of endotracheal tube. The authors recorded the time of laryngeal mask insertion, the success rate of ventilation, the success rate of the first attempt of endotracheal intubation, the number of attempts of endotracheal intubation, the time from insertion of the LMA CTrach to the completion of tracheal intubation. Results The LMA CTrach insertion was successfully completed in all but 2 patients. In 78 patients with good ventilation, the first attempt of endotracheal intubation failed in 5 patients. Except for unsuccessful ventilation in 2 patients and intubation failure for 3 times in 3 patients, the endotracheal intubation by using the LMA CTrach was accomplished in 75 patients. The mean time from insertion of the LMA CTrach to the completion of tracheal intubation was 192 s (range, 156～273 s). Conclusions The LMA CTrach system has the ability to align the LMA outlet with the larynx under direct view, and can increase the success rate of intubation and avoid some unnecessary injuries, giving certain advantages for airway management during cervical spine surgery.

0.05).Various degrees of pharyngalgia and hoarseness occurred in 2 patients in the Group Ⅰ,3 patients in the Group Ⅱ,and 2 in the Group Ⅲ,the incidence of complications being not statistically different(?2=0.323,P=0.851).Conclusions Compared with local anesthesia or endotracheal intubation,percutaneous dilational tracheostomy under laryngeal mask airway ventilation offers more stable circulation,higher reliability,and less influence to tracheostomy.This technique may give certain protection against cervical spinal cord injury during anesthetic induction.
