Objective To investigate antibiotic resistance of Neisseria gonorrhoeae strains isolated from female patients. Methods:Antimicrobial susceptibility of N.gonorrhoeae to 7 antibiotics was tested by disk diffusion method and penicillinase- producing N.gonorrhea(PPNG)was confirmed by nitrocefin disk.Results:Of the 95 strains collected,38(40%)were found to be PPNG.No resistance to spectinomycin was identified.The susceptibility rate of these isolates to penicillin,tetracycline, and ciprofloxacin were much lower,only from 0% to 2.6%.More than 90% of the isolates were susceptible to cefuroxime, ceftriaxone,and ceftizoxime.Conclusions:Our study suggests that spectinomycin,cefuroxime,ceftriaxone,ceftizoxime are the first choice for treatment of gonorrhea in female patients.

BACKGROUND: Direct observation of infarcted microvaseular perfusion after cerebral infarction is the most immediate evidence in evaluation of therapeutic effects.OBJECTIVE: To observe dynamic changes in flowing quality and field in cerebral ischemic area in rats so as to qualitatively and quantitatively analyze the microvascular state in pia matral encephali ischemic area and the changes of associated leukocytic flowing velocity and flowing morphology.DESIGN: Randomized controlled experiment was designed.SETTING: Department of Acupuncture and Moxibustion of General Hospital Chinese PLA.MATERIALS: The experiment was performed in Research Room of Microcirculation of General Hospital Chinese PLA, in which, 120 female Wis tar rats of 2-month old were employed and randomized into acupuncture group (36 rats), model group (36 rats), sham-operation group (36 rats) and normal group (12 rats). The first 3 groups were subdivided in 3 hours, 6hours and 24 hours groups according to the prescriptive time divisions, 12rats in each group.METHODS: In acupuncture and model groups, after abdominal anesthesia with pentobarbital sodium, the cranium was opened and the occlusion of meddle cerebral artery was performed in cerebrum with heat-coagulation method. In sham-operation group, anesthesia and cranium opening were performed, but the meddle cerebral artery was not occluded. In normal group, no any management was performed. In acupuncture group, 60 minutes after occlusion of meddle cerebral artery in cerebrum, needling was given on Renzhong (GV 26) and Neiguan (PC 6) with electric stimulation of disperse-dense wave, 4-10 Hz frequency and 0.4 V of intensity, lasting for 5 minutes. Afterwards, pecking-acupuncture technique was done on Renzhong (GV 26) to achieve strong stimulation for 10 seconds. In shamoperation and model groups, the rats were in process of grasping and fixation, but acupuncture was not applied. Vascular endotheliocyte fluorescence staining and leukocyte fluorescence tracing method were applied, in combination with microscopic video system and computer imaging analyzing system, to observe in dynamic and quantitatively the influences of acupuncture on pia matral encephali microvascular morphology, density and blood flowing velocity at 3 hours, 6 hours and 24 hours after cerebral occlusion of meddle cerebral artery.morphology, density and blood flowing state at various time divisions observed directly microscopically and vascular endotheliocyte morphology and the state of brain tissue which near the microvascular after infusion with velocity in infarcted area at various time divisions measured in quantity in each group.microvascular endotheliocytes were colored worse and more fluorescent exudation appeared. Those were better remarkably in acupuncture group ty: That in model group was lower than normal group. That at 3 hours, 6hours and 24 hours in acupuncture group was higher remarkably than model group [(6.92±0.42), (3.25±0.52) pces/visual field; (7.61 ±0.51),(3.68±0.32) pces/visual field; (8.24±0.72), (5.49±1.2) pces/visual leukocyte velocity: That in model group was lower remarkably in normal group. That at 3 hours, 6 hours and 24 hours in acupuncture group was higher remarkably than model group [(1 193±358), (600±261) μm/s;(1 112±267), (517±115) μm/s, (1 766±293), (611±291) μm/s, q=4.608.28, P ＜ 0.01].CONCLUSION: At early stage of cerebral infarction, broken blood flow is severe in artery, vein and capillary in ischemic area; the numbers of opened vessels are few, flow rate is slow down and cerebral perfusion is unsatisfactory. Acupuncture amaliorate the microcirculation perfusion state in ischemic area, increases the numbers of opened vessels and improves flowing morphology of blood cell.

ObjectiveTo establish a method to induce heterotopic ossification (HO) after spinal cord injury. Methods10 New Zealand White rabbits underwent a complete transection of the thoracic (T10) spinal cord. Just after transection, the right hind limb of every rabbit was immobilized with a plaster support to keep the knee in extension and the hip unrestricted. The plaster was temporarily removed once a day (six times per week) to allow the knees passively mobilized at the maximum range for 5 min. Local swelling, local skin temperature and grade of ossification of the paraplegic limbs were observed. After 5 weeks, the rabbits were sacrificed, and the quadriceps muscles of the right hind limbs were removed for the histological examination. ResultsAfter 5-week immobilization and temporary passive mobilization, HO was successfully induced in all 10 rabbits. There was local skin temperature increase and local swelling in the right hind limbs. The histological changes were similar to those observed in clinical HO. Conclusion5-week immobilization and temporary passive mobilization approach may successfully induce HO, and it may be used to study the pathogenesis of HO after spinal cord injury.
