OBJECTIVE: To analyze the bacterial distribution of secretions in post-traumatic cases with bone infections and summarize the drug treatments in practice, thus to provide reference for treatment of bone infections. METHODS: The clinical data of traumatic patients with positive secretion cultures were collected from January to October in 2012. RESULTS: Eighty-one cases of positive secretion cultures were selected, of whom 57 (70.37%) patients had single bacteria infection, 24 (29.62%) cases had mixed infections. Staphylococcus aureus, coagulase-negative staphylococci, enterobacter cloacae, escherichia coli and pseudomonas aeruginosa were common pathogens. All the patients underwent surgical treatment and intravenous antibiotic therapy during hospitalization. Nineteen cases were implanted with antibiotic bone cement and 2 cases received local lavation. CONCLUSION: Post-traumatic bone infections are mostly caused by single bacteria and Gram-positive bacteria. Topical antibiotic bone cement treatment has become an effective treatment for bone infections.

Infection is one of the most familiar complications in children with idiopathic nephrotic syndrome.Although vaccination is an effectual measure in prevention of secondary infections, it still faces many problems.On the one hand, children′s own immune status (immune system dysfunction, administration with immunosuppressants, etc.) lends additional uncertainties to whether the immune system can produce sufficient protective antibodies after vaccination.On the other hand, potential risks (recurrence of nephrotic syndrome and induction of vaccine related diseases) need to be comprehensively assessed at the time of vaccination.In this paper, the safety, effectiveness and timing of va-ccination in children with nephrotic syndrome in the post-COVID-19 period were summarized, and possible problems of vaccination against severe acute respiratory syndrome Coronavirus 2(SARS-CoV-2) were discussed.

Objective To investigate the effects of intrathecal different doses of dexmedetomidine hydrochloride in spinal block by ropivacaine hydrochloride . Methods Forty lower limb surgery scheduled for elective under spinal anesthesia, were randomly divided into 2 groups (n = 20 each): the control and the treatment groups.The control and the treatment group were intrathecally injected with 4,12 μg dexmedetomidine hydrochloride respectively.The 0.75% ropivacaine hydrochloride 1.5 mL was injected for spinal anesthesia.SBP,DBP,HR,SpO2 and Ramsay Sedation Score were recorded before the spinal anesthesia conduct and thereafter every five minutes. And the onset and duration of block were recorded,adverse reaction like nausea, vomiting and respiratory depression were also observed. Results Compared with the control group,the onset of sensory block was shorter [(6.9±2.6) min vs (8.7±2.9) min] (P<0.05),and the duration of sensory and motor block was longer in the treatment group[(130.8±30.1) min vs (115.9±23.9) min] (P<0.05) and [(145.9±29.0) min vs (130.0±30.1) min] (P<0.05). Conclusion Intrathecal dexmedetomidine hydrochloride at 12 μg improves anesthesia via shortening the sensory block onset and prolonging sensory and motor block,which maintains hemodynamically stable,and does not generate adverse reactions as nausea,vomiting,bradycardia and respiratory depression.

Objective To investigate clinical features and anterior surgical results of cervical myelopathy in patients more than 70 years of age. Methods Twenty aged patients with cervical myelopathy who underwent anterior decompression with bone graft surgery were reviewed. Neurological function was assessed using a scoring system proposed by the Japanese Orthopaedic Association (JOA score). The clinical results and complications were compared with the control group which included 31 patients with multisegmental cervical myelopathy and less than 69 years old and underwent the same operation. Results The preoperative mean JOA score was 9.3 (ranged from 3 to 14) and the JOA score at latest follow-up averaged 13.4 (ranged from 8 to 17) in the aged patient group. 68 percent patients had achieved an excellent or good result and the recovery rate was 58%. 71 percent patients had achieved an excellent or good result and the recovery rate was 67% in the control group. No statistical difference was found in the excellent and good result rate or the recovery rate of JOA score between the aged group and the control group (?字2=0.04, P=0.85;t=1.12, P=0.138). The incidence of surgical related complications in the aged group was 35% (7 cases), which was considerably higher than that in the control group (3 cases, 10%) but without statistical difference (?字2=3.47, P=0.06). In the preoperative flexion-extension stress lateral radiographs, the incidence of cervical instability was higher in the control group (8 cases, 26%) than that in the aged group(1 case, 5%). Conclusion 1) Multilevel lesion induced by overcompensation for cervical instability are the probable cause of myelopathy in aged patients. 2) Anterior decompression is beneficial to improve the neurological function and life style in the aged patients with cervical myelopathy, but associated with a high incidence of surgical complications.
