Objective To identify novel proteins of human adipocytes by proteomic study,and analyze their strueture and function.Methods The expressed proteins of human adipocytes were identified by 2-D electrophoresis and mass spectrometry,and the structure and function of the novel proteins were predicated via bioinforrnatics.Results My027 is a novel protein of human adipocytes identified by 2-D electrophoresis and mass spectrometry.This protein was confirmed by RT-PCR,sequencing,and prokaryotic expression.My027 protein is located in the cytoplasm and has highly conserved structure,indicating that it is an important functional protein. This protein is highly homologous to glyoxalase superfamily with a whole domain of glyoxalase.It shares 96.7% homologous to glycoxalase between 141-253 amino acids and 95.7% homologous to glycoxalaseⅠbetween 144-244 amino acids.Conclusion The results show that protein My027 appears to have the same function as glyoxalaseⅠ.

Objective To improve our understanding concerning radiographic manifestations of cryptogenic organizing pneumonia(COP).Methods The diagnosis of cryptogenie organizing pneumonia was made based on clinical and radiological features,and was verified with lung biopsy and pathological examination in 23 eases.All data were analyzed and relevant literatures were reviewed.Results CT scans revealed multi-patch shadows,patchy air-space consolidations in 15 cases,often located in predominantly subpleural and(or)both inferior lungs,with or ground-glass opacities,bronehieetasis,and cords.Lesion sites changed over time in some patients.Cortieosteroid treatment led to significant improvement in most cases.Conclusions The diagnosis of cryptogenic organizing pneumonia required the converging evidence from clinical and radilogieal manifestations as well as pathologies.It is important to appreciate CT manifestations of COP.

Objective To investigate the processing characteristics of locative prepositions in patients with Chinese aphasia,and to provide the theoretical evidence for the rehabilitation of aphasia.Methods Twenty aphasic patients caused by left-hemisphere stroke and twenty matched normal controls were studied.Using the locative prepo- sition repeating task(single words,locative preposition phrases and words in sentences),the comprehension task, filling-gap task,the visual-spatial function task and the short-term memory task,we compared the performance be- tween these two groups.Results The aphasic patients had more difficulty in repeating locative prepositions in sen- tences,in comprehension task and filling-gap task,their short term memory was impaired.Both groups did well in re- peating single words and phrases.Conclusion The processing of locative prepositions was impaired in Chinese aphasics.The repetition of locative prepositions was more difficult than that of phrases and single words.The preposi- tions were often omitted.It might be due to the impairment of their short-term memory,or it might have something to do with role they played in the syntactic structure.The latter might also impact the comprehension and filling-gap score.We should make plans before rehabilitation therapy.

OBJECTIVEThe study aims to find out the fluctuating curve of the intra-articular pressure in temporomandibular joint with sudden-onset, persistent, severe closed lock and discuss the mechanism of its formation. We also investigate the effects of the arthrocentesis.

METHODS20 affected sides in 16 patients were collected. A No. 8 syringe needle was used to pierce into the upper compartment of TMJ. The pre-arthrocentesis intra-articular pressure was measured by the pressure transducer via the flexural rigid tubing at open and close bite. The curve and mean value were documented during the operation.

RESULTSThe patients with sudden-onset, persistent, severe closed lock had significantly low negative intra-articular pressure in their affected temporomandible joints. The average pressures was (-9.947 +/- 8.854) kPa at open bite and (-6.475 +/- 4.147) kPa at close bite.

CONCLUSIONThe TMJs with sudden-onset, persistene, severe closed lock has particular characters on etiology and clinical behavior. Arthrocentesis is one of the effective treatments to the diseases.

Objective: To evaluate the therapeutic effect of cystic de compression (CD) operation autosomal dominant polycystic kidney disease(APKD) based on clinical material, experience and related theory. Methods: Thirty-nine APKD received CD operation(unilateral 31 cases, bilateral 8 cas e s) in our hospital from 1985 to 1995. Four main parameters, cystic renal enlargi ng rate(CRER)，lumbar pain recurring rate(LPRR)，blood pressure elevating rate(B PER) and renal function abnormal rate(RFAR), were observed 3, 6, 12, 36 and 60 months after CD operation. And the changes were analyzed based on related theory . Results: The changes of 4 main parameters on 5 different time points post operation in unilateral 31 cases were:（1）CRER 19.4%,38.7%,61.3%,1 0 0% and 100%; （2）LPRR 12.9%,48.4%,71.0%,100% and 100%; （3）BPER 6.5%,22.6%,4 1.9%,71.0% and 96.8%;（4） RFAR 3.2%, 12.9%,22.6%,74.2% and 96.8% respectively. Conclusion: During a short period, CD operation can relieve th e lumbar pain, but it is not certain for improving CRER,BPER and RFAR. in the lo ng run, the therapeutic effect is not sure.

OBJECTIVE: To establish standardized methods and parameters of the isolated heart coronary angiography through the experiment of in vitro porcine heart by MSCT. METHODS: Based on different perfusion volume (50, 60 and 70 mL) and different perfusion-imaging time (5, 10 and 20 min), the in vitro porcine coronary artery was injected liposoluble and water-soluble contrast agents using remodel angiography equipment and scanned by MSCT. And the 3D image results were compared. The images were recorded and evaluated by 2 radiologists and analyzed by statistical software. RESULTS: Liposoluble contrast agent affected the images by damaging and infiltrating the fats around the coronary artery, while the water-soluble contrast agent didn't affect the images. The groups with 60 mL or 70 mL perfusion and 5 min perfusion-imaging time had the best images. CONCLUSION The suitable parameters of the angiography lay the foundation of postmortem coronary angiography.

OBJECTIVETo evaluate the effects of microscopic observation drug susceptibility (MODS) in detecting susceptibility of Mycobacterium tuberculosis (MTB) onto four first line anti-tuberculosis drugs.

METHODThe 24-hole cell culture plates were used to test drug susceptibility of MTB on liquid medium, and the best detecting condition of MODS assay was probed; 66 clinical isolates susceptibility to streptomycin (S), isoniazid (H), rifampin (R) and ethambutal (E) were evaluated by using MODS assay and Lowenstein-Jensen (L-J), thereafter, all the inconcordance of isolates between MODS and L-J were tested for the minimal inhibitory concentrations (MIC).

RESULTSConcordance rate of the susceptibility to S, H, R and E in 66 clinical isolates detected by MODS and L-J was 97.0%, 90.9%, 95.5% and 86.4% respectively. If the results obtained by L-J were taken as a golden standard, the sensitivity, specificity, positive and negative predictive value (PPV and NPV) as well as accuracy of susceptibility test to S detected by MODS was 96.0%, 97.6%, 96.0%, 97.6% and 97.0%; 100%, 85.4%, 81.0%, 100% and 90.9% to H; 96.2%, 95%, 92.6%, 97.4% and 95.5% to R; 73.7%, 91.5%, 77.8%, 89.6% and 86.4% to E. There were 20 inconsistent results of 16 isolates by comparing MODS with L-J, and MIC yielded 16 results of those 14 isolates showing identical results with those of the MODS, while 4 results of other 4 isolates identical with L-J.

CONCLUSIONMODS method simultaneously provides drug susceptibility to S, H, R and E. MODS might be one of the rapid tools to diagnosing multidrug-resistant tuberculosis as it is rapid, simple, inexpensive and has high concordance with L-J drug susceptibility test.

OBJECTIVETo study gene expression of collagen types IX and X in human lumbar intervertebral discs during aging and degeneration and to explore the role of collagen types IX and X in disc degeneration.

METHODSFetal, adult and pathologic specimens were subjected to in situ hybridization with cDNA probes to investigate mRNA-expressions of types IX and X collagen gene.

RESULTSIn fetal intervertebral discs, positive mRNA hybridization signals of type IX collagen were concentrated in the nucleus pulposus and the inner layer of anulus fibrosus. Interstitial matrix of the nucleus pulposus also showed positive type X collagen staining. Positive mRNA hybridization signals of types IX and X were not detected in the middle and outer layers of anulus fibrosus. In adult specimens, expression of type IX collagen mRNA was markedly decreased. No hybridization signals of type X collagen was observed. As for pathological specimens, there was no gene expression of type IX collagen. In severe degenerated discs from adults, there were focal positive expressions of type X collagen.

CONCLUSIONSObvious changes of collagen gene expression occur with aging. Expression of type IX collagen decreases in adult and pathological discs. Results of type X collagen expression suggest that type X collagen is expressed only in older adult and senile discs (i.e., when disc degeneration has already reached a terminal stage), indicating the terminal stage of degeneration.
