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.

[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 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.

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.

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.

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.

BACKGROUND: The commonly used culture methods for primary intervertebral disc cells are type Ⅱcol agenase alone digestion method, and type Ⅱ col agenase combined trypin digestion method. However, the acquired cells are few. OBJECTIVE: To acquire nucleus pulposus cells from human degenerative intervertebral disc using a systemic and simplified method. METHODS: Nucleus pulposus cells were isolated and cultured. The morphology of nucleus pulposus cells was observed under inverted phase contrast microscope every day. Primary and subcultured cellsuspension was applied for the determination of cel viability using trypan blue staining. The cel growth was detected with MTT assay. The cel morphology was observed under laser confocal microscopy. RESULTS AND CONCLUSION: Nucleus pulposus cells were successful y isolated from from human degenerative intervertebral disc using the improved method, and cells were subcultured to passage 3. Primary cells were fusiform shaped, while cells at passage 1 and 2 were triangle or polygonal, which were similar to fibroblasts. When cells almost reached the confluence, the cells showed slabstone-like appearance. Trypan blue staining showed that, the primary cel viability was 99%, and passage 3 cells had 93%-95% viability. The proliferation of nucleus pulposus cells gradual y decreased as the generation increased. Compared with passage 1 cells, passage 2 and 3 cells at logarithmic phase trended to be smoother. The cel morphology observed under laser confocal microscopy was similar to the results under phase contrast microscope. The improved simple method can successful y acquire a variety of cells from human degenerative intervertebral disc, and these cells show fine biological properties.
