Objective To quantitatively estimate upper motor neuron (UMN) lesion with the triple stimulation technique (TST) in amyotrophic lateral sclerosis (ALS). Methods Fifty ALS patients and 22 normal controls were enrolled in the study. Patients were examined clinically with conventional transcranial magnetic stimulation (TMS) and TST at abductor digiti minimi. Central motor conduction time (CMCT),motor evoked potential ( MEP), resting motor threshold ( RMT), compound muscle action potential ( CMAP), modified ashworth scale ( MAS), Medical Research Council scale and modified ALS scale were assessed and their correlation to disease progress was analyzed. Results The TST amplitude ratio was significantly decreased in ALS patients with UMN signs(28 cases 62. 0% (40. 7%, 75.9% ) ), compared with controls ( 96. 9% ± 2. 6% ) and ALS patients without UMN signs ( 22 cases 95.6% ( 85.4%,100. 0% ) ;Z = -4. 827, -5.435, both P =0. 000). The abnormal rates of the TST amplitude in ALS with UMN signs, ALS without UMN signs and controls were 89. 3%, 27.3% ,9. 1% respectively. The abnormal rates of the TST amplitude, the latency of MEP, CMCT, RMT in detecting UMN lesions were 89. 3%,64. 3%, 53.6%, 64. 3% , 78. 6%, respectively. The TST amplitude was significantly correlated to tendon reflex in right arm ( r = 0. 690, P = 0. 000), with modified ashworth scale ( MAS, r = - 0. 772,P = 0. 000),with diagnostic degree ( r = 0. 483, P = 0. 000), with RMT ( r = - 0. 774,P = 0. 000), the latency of MEP (r = - 0. 444, P = 0. 005 ), motor evoked potential/compound muscle action potential of erb' s ( MEP/ CMAPerb, r = 0. 685, P = 0. 000 ), MEP/CMAPerb in facilitation ( r = 0. 770, P = 0. 000). Conclusions TST appears to be a more accurate and sensitive measure of detecting and quantifying UMN abnormality in ALS patients than the other parameters. TST may reveal the subclinical UMN impairment in ALS and provide an accurate diagnosis assessment for UMN loss in ALS and an objective scale for monitoring the progression of disease.

Objective:To investigate the value of serum matrix metalloproteinases- 9(MMP-9) level in the diagnosis of recurrence of endometriasis(EMs) after operation.Methods:Sixty-nine patients who had a previous operations for endometriosis were recruited in the study from February 2002 to March 2005. All the patient were examined by laparoscopy 6-12 months later after surgery. The serum were collected from the 69 patients and 25 health women for MMP-9 level measurement. ELISA was used to measure the level of serum MMP-9.Results:Twenty-two recurrent patients were diagnosed by Laparoscopy. The level of serum MMP-9 were 252.21?17.90 ng/ml in patients with recurrent endometriosis, 31.26?1.84 ng/ml in patients without recurrent endometriosis, 12.93?0.57 ng/ml in women without endometriosis. There was a clinical significance between the recurrent endometriosis group and non-recurrent endometriosis group and health women. The sensitivity for detection of recurrent endometriosis was 90.9% and the specificity was 85.1% using serum MMP-9 profile.Conclusion:Serum MMP-9 measurement is a sensitive, specific and non-invasive methods for the diagnosis of recurrent endometriosis.

OBJECTIVE To investigate the current situation and rationality of clinical usage of antibacterial drugs in our hospital and to find out corresponding supervision measures. METHODS According to the same method and criterion,3343 medical records of discharged patients in 14 departments were investigated retrospectively by utilizing the designed questionnaire. RESULTS The total application rate of antibacterial drugs was 60%,and the rate of preventive usage took up 41% of the total application rate,the application rate of cephalosporins was the highest,and that of quinolones was the next.For the combined usage of drugs,1 150 patients were treated with one drug,730 were treated with two drugs,and 99 were treated with more than three drugs.The treatment period of 1 086 patients was less than 7 days. CONCLUSIONS The usage of antibacterial drugs should be supervised more intensively and the training for medical personnel be strengthened to improve their knowledge of using antibacterial drugs,in order to achieve the rational usage of antibacterial drugs.

0.05).After treatment,blood serum E2 level in group M was (74.18?22.32) pmol?L-1,whereas that in group D was (24.96?3.94)pmol?L-1,there was significant difference(P0.05).Conclusion Clinical symptoms of patients with recurrent endometriosis in two groups are improved.Serum E2 level in group M remains in the follicular phase,but group D declines to postmenopausal range.Mifepristone does not result in lack of estrogen,ovulation recovers rapidly after treatment in group M compared with group D.Mifepristone and danazol have not obvious impact on blood serum cortisol.

Objective To look for different expression of proteins between T and B lymphoma cell lines and normal peripheral blood lymphocytes by surface enhanced laser desorption/ionization-time of flightmass spectrometry (SELDI-TOF-MS) technology. Methods T and B lymphoma cells were conventionally cultivated, and logarithmic phase cells were collected for experiment. The normal lymphocytes were separated from peripheral blood of healthy persons. Proteins were extracted from the total protein of various cells, and were detected by SELDI-TOF-MS technology. SPSS 13.0 statistical software was used to statistical analysis and P ＜0.05 was considered as statistically difference. Results There are six differentially expressed proteins between T/B lymphoma cell lines and health human peripheral lymphocyte. There are seven differentially expressed proteins between B and T lymphoma cell lines. Conclusion The levels of proteomics were significantly different among T, B lymphoma cell line and normal lymphocyte. Application of SELDI-TOF-MS technology probably is some benefit on screening molecular markers of lymphoma. Moreover it is possible to lay the preliminary foundation for pathogenesis and targeted treatment of lymphoma.

Objective To analyze the symptoms and signs in forty-five Lambert-Eaton myasthenia syndrome (LEMS) patients retrospectively. Characteristics of electrophysiological examinations were investgated. Methods Forty-five LEMS patients were reviewed and information gathered regarding clinical complains neurological symptoms, and other concomitant diseases. The records showed that repetitive nerve stimulation (RNS) and nerve conduction velocity (NCV) were performed in all patients. Needle electromyography (EMG) and skin sympathetic response (SSR) were performed in some patients. Results (1) The mean age of neurological clinical onset age was (51.2 ±6. 8) years old. The two most common symptoms were slight weakness of lower extremities ( n = 35 ) and upper extremities (n= 5). Dysarthria was found in 3 patients and neck weakness in 2 patients. Tendon reflex decreased and disappeared in 38 patients. Autonomic nervous system manifestations were presented in 30 patients. (2) RNS increasing was observed in all patients from 156% to 636%. Low frequency RNS abnormalities were found in 29 patients.Sensory nerve conduction velocity abnormalities or sensory nerve conduction velocity combined motor nerve conduction velocity abnormalities were found in 19 patients ( 42% ). Of the 30 patients who underwent a needle EMG examination, 20 had myogenic or neurological damage. Thirteen abnormal findings were observed in 25 patients who underwent SSR examination. Conclusion The most common manifestations were weakness in lower extremities and autonomic nervous system dysfunction. Many abnormal electrophysiological results were found in LEMS patients, including NCV and EMG abnormalities. These findings indicated that clinical manifestations exceed the neuromuscular junction and perhaps included the peripheral nerve and muscle.
