OBJECTIVETo investigate different treatment methods for stage-Is testicular mixed germ cell tumors (TMGCTs).

METHODSWe retrospectively analyzed the clinical data about 3'cases of stage-Is TMGCTs (aged 26-39 years) treated in the 175th Hospital of PLA, reviewed relevant literature, and explored the clinical characteristics of TMGCTs.

RESULTSOf the 3 patients, 1 was treated by radical orchiectomy, 1 by radical orchiectomy + retroperitoneal lymph node dissection + BEP chemotherapy scheme, and the other by radical orchiectomy + radiotherapy. The pathological components of TMGCTs were immature teratoma, seminoma, spermatocytoma, chorioepithelioma, embryonal carcinoma, and yolk sac tumor. No recurrence or distant metastasis was found during the 24-month follow-up after surgery.

CONCLUSIONThe diagnosis of TMGCTs primarily depends on physical examination, ultrasonography, MRI, and measurement of serum tumor markers, while its confirmation necessitates pathological examination, and its treatment is basically radical orchiectomy.

The definition of sub-health was studied from the angle of tumor dormancy again. We believe it is necessary to further supplement the present definition, diagnosis criteria, and assessment means. The definition of sub-disease and the division of a disease into four development stages (health --> sub-health --> sub-disease --> disease) were also brought up. Furthermore, we believe that application of regulating sub-health as preventive and therapeutic strategies for tumor is an anti-cancer method with Chinese features, which enriches the modern theories of tumor prevention and therapy.

To investigate the genetic diversity among wild Dipsacus asperoides in China, 66 germplasmic resources of D. asperoides were analyzed by Start Codon Targeted Polymorphism (SCoT) molecular markers. Genetic distance was calculated by TREECONW software and the systematic diagram of genetic relationship was clustered by UPGMA method. The results showed that the totals of 181 bands were detected using 20 primers , among which 109 were polymorphic bands. The average percentage of polymorphic bands was 60.13%. Genetic distance changed from 0.030 6 to 0.181 4. The clustering results showed that there was no significant correlation between the classification of the wild D. asperoides and their geographical origin. The relatively high genetic diversity of D. asperoides provides the basis for breeding new varieties.

The effect of the complement C1q expression on total hepatic ischemia-reperfusion (I/R) injury in rats was investigated. Sixty healthy male Sprague Dawley (SD) rats weighing 180-200 g were randomly divided into 5 groups: sham-operation group (S group, n=12); group of I/R for 1 h (I/R 1 h group, n=12); group of I/R for 3 h (I/R 3 h group, n=12); group of I/R for 6 h (I/R 6 h group, n=12); group of I/R for 24 h (I/R 24 h group, n=12). The hepatic I/R model of rats was established, and liver tissues were obtained 1 h, 3 h, 6 h and 24 h after hepatic I/R, respectively. Furthermore, the tissues were stained using hematoxylin-eosin, and the liver injuries of rats were observed using a microscope. The malondialdehyde (MDA) level and superoxide dismutase (SOD) activity in liver tissue were determined. Real-time polymerase chain reaction (PCR) and Western blotting were used to detect the expression levels of C1q mRNA and protein, respectively. As compared with the S group, the histopathological changes in I/R 1 h-24 h groups were gradually aggravated with the extension of I/R time. As compared with the S group, SOD activity and MDA content in the I/R groups were reduced and increased respectively with the extension of I/R time (P<0.01). Furthermore, the C1q expression at mRNA and protein levels in the I/R groups (especially in the I/R 3 h group) was significantly higher than that in the S group (P<0.05). It is suggested that C1q expression may play a principal role in hepatic I/R injury, particularly at the early stage of perfusion.

OBJECTIVETo examine whether TLR-4 has an effect on hemorrhage induced changes in lung, and to investigate the change of heme oxygenase-1 (HO-1) on acute lung injury (ALI) induced by hemorrhagic shock in mice.

METHODSForty-eight male mice, including C3H/HeN mice and C3H/HeJ mice, were randomly divided into sham group (n=12), hemorrhagic shock group with twelve mice in each phase. Blood pressure (BP) was monitored continuously by attaching carotid artery catheter to a strain gauge pressure transducer/ polygraph. Arterial blood samples were taken for blood gas analysis. A mouse model of non-lethal hemorrhagic shock and resuscitation was used to observe pulmonary myeloperoxidase (MPO) activity and wet/dry weight ratio (W/D). The expression of HO-1 was observed by means of RT-PCR and immunohistochemistry. IL-6 and IL-10 in lung tissue homogenate were assayed by enzyme-linked immunosorbent assay (ELISA). The pulmonary pathologic changes were observed under electron microscope and light microscope.

RESULTSCompared with sham group, the expression of HO-1 in lung tissue was significantly higher in Hem 24 h and Hem 48 h of C3H/HeN mice (P less than 0.01). The expression of HO-1 mRNA and the levels of IL-6, IL-10 and MPO in lung tissue were markedly increased in Hem 24 h (P less than 0.01 or P less than 0.05); Compared with C3H/HeN mice, the expression of HO-1 mRNA and the levels of IL-6 and IL-10 in C3H/HeJ mice significantly decreased in Hem 24 h and Hem 48 h (P less than 0.01 or P less than 0.05), and the W/D, MPO in C3H/HeJ mice were obviously lower in Hem 24 h (P less than 0.05). The injuries of lung tissues after hemorrhagic shock have been demonstrated by histological examination with electron microscope and light microscope.

CONCLUSIONSTLR-4 and HO-1 might modulate the balance of pro- and anti-inflammatory processes in inflammatory reaction of hemorrhagic shock-induced ALI, and the activation of Toll-like receptor might induce the transcription activity of HO-1, which may play a key role in acute lung injury.
