The acurate diagnosis of invasive fungal infection(IFI)is the key point for the treatment and proginosis for IFI patients.Pathological diagnosis is still considered as the gold standard for the IFI diagnosis although difficult.The regular procedures for IFI diagnosis including culture and direct examintion are often low yeilding,the discrimination for contamination and infection is hard.Imaging manifestations are nonspecific but have important suggestive values.The detection for molds antigen content is useful,but its sensitivity and specifity need to be improved.The proper diagnosis for IFI relys on the combination of clinical characteristic,imaging manifestion and serial observation.

Muscle spasticity is one of the common complications in the paraplegic patients who suffer from spinal cord injury (SCI). Spasticity can result in limbs pain, joint contracture and malformation, then affects walking and the capability of keeping the posture in wheelchairs. Moreover, spasticity can increase the incidence rate of heterotopic ossification and fracture and seriously affects patients' daily life and rehabilitation therapy accordingly. There are many kinds of treatments aimed at spasticity at present, such as drug, exercise therapy, physiotherapy, nerve block treatment, operation treatment, and so on. However, single treatment doesn't achieve good effect. So it is common that many kinds of treatments are combined to treat spasticity. This article simply introduces the mechanism, symptom and evaluation of the muscle spasticity after SCI and discusses in full the treatment of the muscle spasticity by reviewing recent literatures.

The emerging technologies change rapidly in the medical field, refresh the medical ethical scenari-os, brought some medical ethical blind spot.Therefore, building the platform of academic research, making use of the new media, MOOC and“flipped classroom”, inheriting the native“The Spirits of A Great Physician” in tradi-tional Chinese medicine and western medicine, life ethics education and sublation of new exploration, the ideolog-ical and moral education for medical students is expected to be improved in China.

[Objective]To evaluate therapeutics for lumbar tuberculosis. [Method]Data from 65 patients treated with five different therapeutics were retrospectively reviewed.Group A(n=14) was treated with focal debridement.Group B(n=15) with focal debridement and bone grafting fusion.Group C(n=9) with posterior focal debridement plus bone grafting fusion and internal fixation.Group D(n=12) with posterior fixation and anterior focal debridement plus,bone grafting fhsion.Group E(n=15) with anterior focal debridement plus bone grafting fusion and anterior internal fixation.Patients all received routine support and anti-tuberculosis therapy before and after operation.Follow-up, erythrocyte sedimentation rate was studied,and bone fusion and kyphosis correction with X-ray plain film and 3D-CT reconstruction were evaluated.[Result]There were not damages occurring in the great vessels,nerves or ureters.No recurrence was found during the follow-up of 12~16 months(average 13 months).Grafting bone were all fused after 4~6 months with an average time of 3.8 months.There was no missing of angel of kyphosis correction,complications of looseness or break of internal fixation.[Conclusion]Efficient anti-tuberculosis therapy and the debridement is the key for treatment of tuberculosis.The selection of fusion or internal fixation is depended on the severity of tuberculosis.Reasonable selection may improve the therapeutic effect of lumbar tuberculosis.

The growth and pigment production of 47 strains on casein medium were studied comparatively.T4 and Neurospora crassa AS 3.1602 were selected for their capacity of producing melanin on five different culture media. Melanin produced by T4 was investigated, and T4 was identified as Proteus mirabilis primarily.

ObjectiveTo investigate the effect of varied hyperglycemia and durations on preventing peripheral neuropathy (PN) with methylcobal in diabetic rats.Methods80 Sprague Dawley rats were selected and randomly chosen 16 as normal control (NC) group, others 64 animals as diabetic model induced by alloxan. The model rats were evenly divided into relatively good control (GC) group and relatively poor control (PC) group based on levels of hyperglycemia regulated with exogenous insulin. 16 rats of each GC/PC group were intramuscularly injected with methylcobal (500 μg/kg). The sensory nerve conduction velocity (SNCV), motor nerve conduction velocity (MNCV) and evoked potential amplitute (EPA) of sciatic nerve of rats were detected by evoked electromyogram respectively at 2nd, 8th and 12th week after onset of diabetes. Fructosamine in serum was also detected.ResultsThe rats injected with methylcobal had a significantly delayed reduction of SNCV, MNCV and EP in GC group (fructosamine,1.0 mmol/L) than that in PC group (fructosamine, 1.2 mmol/L) ( P<0.05～0.01). Up to 8th week after onset of diabetes, there was no obvious difference in physioelectroparameters between the GC group and NC group. At 12th week after onset of diabetes, physioelectroparameters in the PC group fell to the level of non-methylcobal injected group. No effect of methylcobal on blood glucose revealed in any groups ( P>0.05).ConclusionMethylcobal has a beneficial effect on delaying the onset of diabetic PN, and is of high efficacy with a good control of diabetic state, especially at early stage.

OBJECTIVE To investigate the transmission process of large scale abrupt diarrhea with unknown reason occurred in hospital,analyze the cause of infection outbreak and the characteristics of Norovirus in hospital and to provide evidence to prevent and control the infection in hospital.METHODS Standardized questionnaire was used on individual,looking over the case of illness and the investigation of outbreak scene,the relationship of various contact type and odds of infection.RESULTS Nine cases were occurred,fifty-two cases were contacted,The morbidity was 17.31%.The feature of Norovirus infection was clear.CONCLUSIONS The first source of infection was an input case.The main transmission way is no protecting close contact.The high risk group is inpatients and their relatives.

For better adaptation to clinical work and scientific research as well as self-development,medical postgraduates are required to improve their reading ability to harvest information from medical English articles.Constructing formal schema based on linguistic schema and enriching content schema can significantly enhance medical English reading ability,according to schema theory and education practice.Therefore,the learning mode was explored based on schema theory and this theory was applied in practice to elevate reading ability by means of reading report.

BACKGROUND: For its extensive sources and specific biological characteristics, heterogeneous deproteinized bone (DPB) as the tissue-engineered scaffold material gets a good application prospect in repair of large segmental bone defects.OBJECTIVE: To prepare scaffold material by compositing modified heterogeneous DPB with recombinant human bone morphogenetic protein 2 (rhBMP2) and evaluate the osteogenic ability in repairing large segmental long bone defects in large-sized animals.METHODS: Twenty-four goats were randomly and evenly divided into three groups: DPB, autologous bone, and DPB+rhBMP2. Bone defects (20% in length) were made in the middle and lower segments of the right tibia of each goat, and according to group design,different bone grafts were implanted and fixed using semi-ring slot external fixer. At 4-24 weeks after surgery, X-ray examination was performed once every other 4 weeks. At 24 weeks after surgery, newly formed bones were taken out for determining the repair effects of bone defects through duat-energy X-ray analysis, histological observation, and biomechanical analysis.RESULTS AND CONCLUSION: The prepared DPB exhibited a three-dimensional porous structure, with a porosity of (78.5±6.45)% and pore size of (472.5±7.02) μm. Time-dependent bone repair was found in each group. Results regarding anti-compression test, three-point anti-bend test, and anti-torsion test were greatest in the autologous bone group, followed by the DPB+rhBMP2 group, and lastly the DPB group. There were no significant differences in tibial bone density, bone mineral content,anti-compression pressure and ultimate pressure, anti-bending load and ultimate toad, anti-torsion torque and ultimate torque between autologous bone group, DPB+rhBMP2 group and normal bone control group. These findings indicate that modified heterogeneous DPB composited with rhBMP2 has osteogenic ability equivalent to autologous bone in repairing large segmental long bone defects in goat tibias. Therefore, it can be applied as tissue-engineered scaffold material.
