Prevalence and risk factors of knee osteoarthritis in Huang-Pu District, Shanghai, China.

Objectives: A community-based survey on the prevalence of knee osteoarthritis (OA) and associated factors was carried out in Shanghai, People's Republic of China.

Methods: Of 2,305 registered residents >or=40 years of age, 2,093 were examined by interview and questionnaire. One hundred ninety knee pain-positive and 510 knee pain-negative subjects received radiography.

[The effects of the plasty of the cavity of auricular concha in the post-mastoidectomy].

Objective: The purpose of this study was to compare the results of mastoidectomy with the plasty of the cavity of auricular concha and the counterpart of mastoidectomy without it at after for 2-6 years followup.

Method: A retrospective analysis of 320 cholesteatoma cases, surgically treated at the department of otorhinolaryngology-head and neck surgery, Renji hospital affiliated to Shanghai No. 2 Medical University, over a 9-year period, is reported.

[Changes of airway responsiveness, and relative factors in asthmatics with remission at puberty].

Objective: To study the airway responsiveness and relative factors in asthmatics with natural remission at puberty.

Method: The airway responsiveness was evaluated by challenge of methacholine (PC20), blood sIL-2R, eosinophil count, basophil count and basophil releasability were detected in 18 asthmatics with remission at puberty (group I), in 20 asthmatics without remission at puberty (group II), and in 30 healthy controls (group III).

Result: The mean value of PC20 in the group I was significantly lower than that of the group III (P < 0.

A preliminary study on intravenous infusion of sodium eicosapentaenoate.

Eicosapentaenoic acid (EPA) and arachidonic acid (AA), made into sodium salt solution (50 micrograms/ml), were used for intravenous infusion. In a preclinical study in dogs, Na-EPA lowered the activity of transminases (glutamic pyruvic transaminase [GPT], glytamic oxaloacetic transaminase [GOT]); however, Na-AA increased the activity of GPT and GOT. In the clinical study, the numbers of leukocytes and lymphocytes of volunteers increased and remained at that level for 3 to 5 days after intravenous infusion.

The epidemiology study of hyperuricemia and gout in a community population of Huangpu District in Shanghai.

Objective: To investigate the prevalence of hyperuricemia and gout in a community population of Huangpu District in Shanghai.

Methods: In the target community, 2037 dwellers were interviewed with relevan questionnares from house to house. According to even house number 1017 blood samples were taken for serum uric acid (SUA) levels measured with the uricase-peroxidase enzymatic method.

Purification, characterization, and pathogenicity of urease produced by Vibrio parahaemolyticus.

Vibrio parahaemolyticus is a halophilic bacterium associated with gastroenteritis and traveller's diarrhea. The urease-positive, Kanagawa-negative V. parahaemolyticus had been isolated from patients and the environment in the Pacific Northwest, first reported by Kelly et al.

[Development of intercellular junction in the human vestibular receptors. A freeze-fracture study].

The intercellular junctions, especially the tight junctions of the inner ear end-organs are considered to act as a barrier to maintain gradients of ions between the endolymph and the perilymph. Thus, the intercellular junctions are of great importance for the function of the inner ear. We have studied the development of intercellular junctions in vestibular end-organs in order to establish a morphological basis for better understandings of the key stage of the development of vestibular end-organs.

[Deleterious effects of calcium on the pathogenesis of ischemic brain damage].

Using atomic absorption spectroscopy, we measured the regional distribution of tissue Ca++ contents of 24 rabbit brains sampled at 2,4,24 and 48 hours after the occlusion of Middle Cerebral Artery (MCAo) with accompanying histopathological examinations with 10 controls. At 2 hours after MCAo, brain tissue Ca++ concentration increased significantly (P less than 0.005) in the ischemic territory and increased further with times, far preceding the detectable pathological findings termed necrosis, which appeared at 12 hours after MCAo.

Traumatic aneurysm of the intracavernous part of the internal carotid artery presenting with epistaxis. Case report.

A 22-year-old Chinese man sustained a gunshot wound through his right eye followed by three episodes of massive epistaxis. Angiography showed a large aneurysm in the intracavernous segment of the left internal carotid artery which was successfully treated by thrombosis with copper wire.
