The lung is one of the earliest organs affected by sepsisassociated with acute lung injury. High mobility group protein B1 （HMGB1） is an important late-actingpro-infl ammatory cytokine involving in the pathophysiology of sepsis. It is also involved in the injuryprocess in the lung, liver and intestine. There has been no report on the involvement of HMGB1 inVibrio vulnifi cus sepsis-induced lung injury.METHODS： Sixty rats were randomly divided into a normal control group （group A, n=10） anda Vibrio vulnificus sepsis group （group B, n=50）. Sepsis was induced in the rats by subcutaneousinjection of Vibrio vulnificus （concentration 6×108 cfu/mL, volume 0.1 mL/100g）） into the left lowerlimbs. The rats in group B were sacrifi ced separately 1, 6, 12, 24, and 48 hours after the infection.Their lungs were stored as specimens, lung water content was measured, and lung pathology wasobserved under a light microscope. The expressions of the HMGB1 gene and protein in the lungswere detected by RT-PCR and Western blot. Data were analyzed with one-way analysis of variance（ANOVA） and the LSD method for pair-wise comparison between the two groups. P〈0.05 wasconsidered statistically signifi cant.RESULTS： Compared to group A （0.652±0.177）, HMGB1 mRNA expression in the lungs ofgroup B was signifi cantly higher at 0 hour （1.161±0.358, P=0.013）, 24 hours （1.679±0.235, P=0.000）,and 48 hours （1.258±0.274, P=0.004） （P〈0.05）, and peaked at 24 hours. Compared to group A（0.594±0.190）, HMGB1 protein expression at 6 hours （1.408±0.567, P=0.026） after infection wassignificantly increased （P〈0. 05）, and peaked at 24 hours （2.415±1.064, P=0.000） after infection.Compared to group A （0.699±0.054）, lung water content was significantly increased at 6 hours（0.759±0.030, P=0.001）,12 hours （0.767±0.023, P=0.000）, 24 hours （0.771±0.043, P=0.000） and 48hours （0.789±0.137, P=0.000） after infection （P〈0.05）. Compared to group A, pathological changesat 12 hours in group B indicate marked pulmonary vascular congestion, interstitial edema andinfl ammatory infi ltration. Alveolar cavity collapse and boundaries of the alveolar septum could not beclearly identifi ed.CONCLUSION： Vibrio vulnifi cus sepsis can lead to injury in rat lungs, and increased HMGB1expression in lung tissue may be one of the mechanisms for injury from Vibrio vulnifi cus sepsis.展开更多

Methods Patients with EAA diagnosed at Peking Union Medical College Hospital from August 1983 to May 2007 were analyzed retrospectively. Their medical records were examined to gather clinical, laboratorial, radiological, and histopathological data. Patients were divided to three phases （acute, subacute, and chronic） according to clinical presentations. Follow-up data regarding treatment response, subsequent radio- logical and pulmonary function studies, and clinical outcomes were collected. Results A total of 21 cases were enrolled. Among them, 11 were subacute, 10 were chronic. The most common exposure was pet birds （6 cases, 28.6%）. The primary abnormality of pulmonary function was restriction and/or reduction in diffusing capacity （12 cases, 63.2%）. The most common findings on high-resolution computed tomography （HRCT） were ground-glass opacities （13 cases, 68.4%） and centri- lobular nodules （8 cases, 42.1%）. Airway obstruction in pulmonary function test, emphysema, hmg cysts, and fibrosis on HRCT were more frequently seen in chronic than in subacute patients, though the differences were not statistically significant. Bronchoalveolar lavage fluid （BALF） showed lymphocytosis. The total＇cell count and the percentage of neutrophils were significantly higher in subacute than in chronic patients （P〈0.05）. Nonnecrotizing granulomas were seen in 8 （47.1%） cases. Improvement or normalization in symptoms, radiography, and pulmonary function test after treatment were seen in all 18 patients with avail- able follow-up data. Five patients recurred. Conclusions The characteristic abnormalities of pulmonary function, findings on HRCT, and pa- thology are essential for all phases of EAA, and the atypical manifestations such as obstruction and fibrosis can also be present frequently, particularly in chronic cases. Differential cell counts of BALF are related to the phase of the disease. The treatment response and prognosis of EAA are good.展开更多

Methods： Specimens of the implanted esophagus, the ＂neo-esophagi＂, were taken for histopathologic study 1, 3, 6, 12, 24 months after operation. Results： The incidence of anastomotic leakage after the artificial esophagus implantation was 3.33%. The perioperative survival rate was 96.67%. The incidence of postoperative stenosis in the ＂neo-esophagi＂ was 81.48%; the stenoses were treated by expanding with esophagoscopy and implanting a stent. Epithelization of the mucosa in the ＂neo-esophagi＂ was completed in 3 to 6 months after surgery Structures such as submucosal muscle layers, mucous glands, nerve fibers, capillaries, etc. were regenerated after 12 months, and then reconstruction of the fibrous connective tissue layer was completed. Conclusion： Implanting a biomaterial artificial esophagus accomplishes safe reconstruction of defects in the esophagus. Advanced cellular structure of ＂neo-esophagus＂ can be regenerated after 1 year. Postoperative stenosis, which is related to hyperplasia and retraction of scar tissue, is still the most common complications which limiting the clinical application of the artificial esophagus.展开更多

Seven of 9 patients had been raised as females, of which the chromosomal karyotype was 46XX in 5 cases, 46XX/46XY and 46XX/47XXY in 2 cases. Two of 9 pa- tients were raised as males, the chromosomal karyotypes being 46XX and 46XX/46XY. All 9 patients had testicular tissue excised, and biopsies of the conserved ovarian tissue were performed. Ovotestis was the most common form of the abnormal gonads; two of 9 patients had bilateral ovotestes, seven had unilateral ovotestes (5 in right side, 2 in left side). In seven patients with a unilateral ovotestis, 6 had a contralateral ovary and one had a contralateral testis. Microscopically, the ovarian tissue of 11 ovotestes, including 6 biopsies from contealateral ovaris, were normal, with many primordal follicles and a few growing follicles. In two of the patients, aged over 15 years, evidence of ovulation was observed. In comparison, the testicu- lar tissue of the ovotestis and the one left inguinal testis was histologically abnormal, with immature semi- niferous tubules, most of which filled with Sertoli cells only. Three of 9 patients married after surgical treatment. Two of these subsequently conceived and delivered of normal infants by cesarean section.展开更多
