Objective To report a case of subcutaneous phaeohyphomycosis caused by Curvularia clavata in China. Methods The skin specimen was collected, and examined by KOH preparation, fungus culture and histopathology. Results A 17-year-old male farmer had dull red, warty and well-defined plaques with some ulceration on his face and his left upper arm for nine years and a history of trauma of his face before the appearance of the lesions. General examination did not reveal abnormal findings except the skin lesions. KOH direct examination showed septate hyphae with irregular branches. On the culture medium the colonies were black in color. Under microscope the conidia were borne singly or in groups at the tip or at the sides of the conidiophores, they were light brown to brown, smooth, straight or slightly curved and clavate, measuring 15 ~ 30 ?m long and 6 ~ 12 ?m thick, with 3 ~ 4 septates. Histopathology showed a granulomatous response. PAS staining showed irregularly swollen or toruloid conidia with branched hyphae. The isolated strain was identified as Curvularia clavata Jain. Conclusion It is the first case report of subcutaneous phaeohyphomycosis caused by Curvularia clavata in China.

Arachidonic acid is an essential fatty acid in human nutrition and a biogenetic precursor of the biologically active prostaglandins and leukotrienes. ?~5 desaturase catalyzes the ?~5 dehydrogenation of di-homo-?-linolenic acid to form arachidonic acid in biosynthetic pathway of arachidonic acid. Using real time PCR technology,the transcriptional expression levels of gene encoding ?5 desaturase in three Mortierella alpina strains M10,M6 and M23,and in different growth phase of high arachidonic acid yielding strain M6,were determined. Results showed that there was a distinct corelationship between mRNA transcript level of ?~5 desaturase gene and biosynthesis of arachidonic acid. Results indicated that ?~5 desaturase plays an important role in arachidonic acid biosynthesis.

OBJECTIVETo explore causes of shoulder pain and propose prevention measures in treating acromioclavicular joint dislocation.

METHODSFrom January 2005 to January 2013, 86 patients with acromioclavicular joint dislocation (Tossy III) were treated with hook plate fixation, and were divided into two groups. Bsaed on recovery of shoulder function mostly, the patients who suffered from rest pain, motion pain were named as shoulder pain group, while the patients without pain were named as painless group. In shoulder pain group, there were 21 cases including 15 males and and 6 females ranging the age from 22 to 62 years old with an average of (40.6±11.2) years old. There were 8 cases were on the left side and 13 cases were on the right side. In painless group, there were 65 cases including 36 males and and 29 females ranging the age from 19 to 65 years old with an average of (40.0±11.3) years old. There were 33 cases were on the left side and 32 cases were on the right side. The time from injury to operation ranged from 3 h to 8 d with an average of 34.6 h. Shoulder function of all patients were normal before injuried. Postoperative pain, activity of daily living (ADL), range of motion, deltoid muscle strength were compared. Anteflexion,rear protraction, abduction and upthrow of shoulder joint were also compared. Postoperative complications between two groups were observed and compared.

RESULTSAll patients were followed up from 12 to 48 months with an average of 18.5 months. Constant-Murley score were used to evaluate clinical efficacy at the least following up, and 13 cases got an excellent results, 5 moderate, 2 good and 1 poor in shoulder pain group ; while 61 cases were obtained excellent results, 3 moderate and 1 good in painless group. There were significantly differences between two groups in Constant-Murley score and activity of shoulder joint (P<0.05). In shoulder pain group, 3 cases were disconnected, 1 case occurred stress fracture, 9 cases were subacromial impingement syndrome, 5 cases occurred subluxation, 1 case occurred plate breakage and 11 cases were acromioclavicular arthritis.

CONCLUSIONChosing individual clavicular hook plate, fulfilling anatomic reset, paying attention to the repair of articular capsule ligament, and reducing hook and bone antagonism between stress is the key point of preventing and decreasing postoperative shoulder pain.

To analyze and compare the protective effects of active components in different ethyl acetate extracts (EAEEPs) from Eclipta prostrate, in order to study the comparison of materials bases protecting normal human bronchial epithelial (NHBE) cells. The MTT assay was taken to compare the protective effect of different EAEEPs on cigarette smoke extracts (CSE) -induced NHBE cells. The ultra-performance liquid chromatography (UPLC) was applied to analyze the content of phenolic acid, coumaric grass ether and flavonoid in EAEEPs. According to the results, all of the eight EAEEPs (0-200 mg x L(-1)) showed certain protective effect on NHBE cells, with statistical difference. Specifically, the total mass of EAEEP VII (89.15 mg x L(-1)) and EAEEP VIII (57.44 mg x L(-1)), which showed the strongest activity, was not the highest, while EAEEP III (132.25 mg x L(-1)) displayed the highest total mass. In the combination with the "component structure" theory, the analysis showed a significant difference in the mass structure among phenolic acid, coumaric grass ether and flavonoid in EAEEP VIII and EAEEP VIII, which were 1.0: 1. 0: 0.5 and 1.0: 1.9: 0.8, respectively. The results suggested a specific optimal "component structure" relationship may exist in EAEEP, which could provide reference for the material base study and quality control.

OBJECTIVETo explore the effect of Ginkgo biloba extract (GBE) on the function of alveolar polymorphonuclear neutrophils (PMN) in severe acute pancreatitis (SAP) rats complicated with lung injury (LI).

METHODSForty-eight adult SD rats were randomly divided into three groups, i.e., the sham-operation group, the SAP group, and the GBE treatment group, 16 in each group. The SAP model was successfully induced by retrograde injection of 5% sodium taurocholate solution into the biliopancreatic duct. Rats in the sham-operation group only received flipping of the duodenum. Those in the GBE treatment group received GBE intervention based on SAP model. Equal volume of normal saline was given to rats in the sham-operation group and the SAP group. Rats were sacrificed at 6 and 12 h after operation respectively. The lung tissue was sampled to evaluate the LI score. The wet/dry ratio (W/D) of lung tissues was detected. The activity of myeloperoxidase (MPO) was measured. Alveolar PMN was harvested by bronchoalveolar lavage. The content of neutrophil elastase (NE) in bronchoalveolar lavage fluid (BALF) was measured by enzyme-linked immunoabsorbent assay (ELISA). The percentage of CD11b/CD18 double positive PMN was detected using flow cytometry. The expression of intercellular adhesion molecule-1 (ICAM-1) and NE protein in the lung tissue was detected by Western blot.

RESULTSCompared with the sham-operation group, significant pathologic lesion occurred in the lung tissue of rats in the SAP group; the pathologic LI score, lung tissue W/D ratio, MPO, and NE content in BALF significantly increased, the expression of ICAM-1 and NE in the lung tissue was obviously up-regulated, and the percentage of CD11b/CD18 double positive PMN significantly increased (P < 0.01). Compared with the SAP group, pathological lesion of the lung tissue was obviously attenuated, and the above indices were all significantly declined in the GBE treatment group (P < 0.01).

CONCLUSIONSExpression of ICAM-1 in the lung tissue and the percentage of D11b/ CD18 double positive PMN were up-regulated in SAP rats complicated with LI, resulting in the adherence of PMN to pulmonary vascular endothelial cells, and then activating PMN to release NE and aggravate LI. GBE could alleviate LI through down-regulating the expression ICAM-1 and CD11b/CD18, and hindering the adherence and activation of PMN to pulmonary vascular endothelial cells.
