OBJECTIVE To establish the distribution and the drug resistance of the pathogens of lower respiratory tract infections in a comprehensive intensive care unit(ICU).METHODS The bacterial culturing and the tests on the antibiotic from the deep phlegm in an ICU of the hospital from 2004 to 2005 were retrospectively analyzed.RESULTS Totally 408 phlegm samples were tested and 216 of them had bacteria,the positive rate was 52.94%.From them were isolated 240 strains of bacteria(among them 12 samples with 2 kinds of bacteria).The strains of Gram-negative bacteria were 172 and the positive rate was 71.7%,there were 35 strains of Gram-positive cocci with the positive rate of 14.6%.And there were 33 strains of fungi,the positive rate was 13.7%.Acinetobacter baumannii occupied the first place.The lowest drug resistance rate of the Gram-negatives was to SCF(0.0%),IMP(17.8%),and LEV((20.0%)).All Gram-positive cocci were sensitive to vancomycin,no vancomycin resistant.Staphylococcus were found.Candida albicans was sensitive to all tested drugs.CONCLUSIONS The isolation rate of A.baumannii is significant higher than reported before and its drug resistance is heavier.It indicated the importance of monitoring bacterial distribution and drug resistance dynamics.

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.

Transcranial magnetic stimulation (TMS) is a non-invasive technique that can activate cortical motor areas and the corticospinal tract without causing the subject discomfort. Since TMS was introduced, numerous applications of this technique have been developed for the evaluation of neurologic diseases. They allow the evaluation of cortex excitability and motor conduction in the central nervous system and have been proved useful in monitoring motor abnormalities and the recovery of motor function. TMS also gives informations on the pathophysiology of the processes underlying the various clinical conditions and contribute to investigate the mechanisms of diseases. In addition, therapeutic use in depression, Parkinson's disease, epilepsy, spinal cord injury and stroke has raised great interest over the past decade. Theapplication of TMS has great potential both as an investigational and as a therapeutical tool in neurology and psychiatry. However, as an infant techniology, there should be further investigation and large randomized trials to be conducted.

High-mobility group box 1 ( HMGB1 ) is a conserva-tive nuclear protein and plays an essential role in maintaining nu-cleosome stability, DNA recombination, replication, repair and transcription. It can be passively released by necrotic cells or ac-tively secreted into extracellular under appropriate stimulus. Re-cent studies show that the activation of HMGB1 signaling is closely related to the progress of lung diseases including lung in-jury, pulmonary fibrosis and lung cancer, while blocking HMGB1 signaling inhibits the pathological process, indicating the therapeutic potential of HMGB1 inhibition in treating these diseases. This review summarizes the role and mechanisms of HMGB1 in such diseases, in order to provide novel evidence for the diagnosis and treatment.

Objective To evaluate the clinical application of HLA matching in highly sensitized recipients of renal allografts.Methods Recipient's panel reactive antibody (PRA) was detected by using ELISA test with Lambda antigen tray (LAT).Donor and recipient HLA classⅠtyping was performed with special monoclonal tray,and HLA classⅡgene typing with micro-sequence specific primers (Micro-SSP).Results There were 104 recipients with anti-HLA class-ⅠIgG antibody,76 with anti-HLA class-ⅡIgG antibody,and 44 with both anti-HLA class-1 and anti HLA class-ⅡIgG antibody respectively in 136 sensitized recipients.HLA class-ⅠIgG antibody positive rate was 11%-97 %,with an average of 49.6%?23.8%;The common public epitopes antibody was not found in each recipient of 13 cases with PRA＜20%,but was found in I2 recipients in 44 cases with PRA be- tween 20%-50%,and 39 recipients in 47 cases with PRA＞50%.HLA class-ⅡIgG antibody posi- tive rate was 17%-100%,with an average of 28.2%?63.8%.The number of cases of 0,1,2,3, 4 MM was 7 (5.1%),26 (19.1%),47 (34.6%),39 (28.7%) and 17 (12.5%) respectively by the standard of conventional HLA antigen matching;however the number of the recipients with 0,1, 2,3 MM was 31 (22.8%),53 (39.0%),36 (26.5%) and 16 (11.7%) respectively according to the rule of HLA CREGs matching and none with 4 MM.Rates of acute rejection in sensitized recipi- ents with 2MM and 3MM HLA-CREGs were 25.0% and 37.5% respectively and were significantly higher than those with 0MM (P＜0.05,＜0.05 respectively).Kidney year-survival was decreased when the number of MM of HLA CREGs matching increased.Conclusion The HLA CREGs matching can improve the ratio of well-matched significantly.Good HLA matching can reduce the incidence of acute rejection in sensitized recipients and increase the survival rate of grafts.

Objective To investigate the value of low positive AFP level for the diagnosis of hepatocellular carcinoma(HCC)when a space occuping lesion was already identified in the liver.Methods The AFP level of 401 HCC cases from January 1999 to October 2006 were retrospectively analyzed.Results 22 cases of small liver cancer underwent reducing surgical resection in our hospital,increasing the quality of life and prolonging survival rate.Con- clusion(1)The AFP level between 20 and 200?g/L is of diagnostic for HCC when a SOL is identified.(2)The clinical reference diagnostic criteria using AFP level more than 20?g/L,instead of more than 200?g/L is helpful for the diagnosis.(3)Combined diagnosis of AFP level more than 20?g/L and ultrasonography or CT scanning yields higher sensitivity and specificity th.an traditional,diagnostic criteria.
