Purpose To investigate the clinicopathological and immunohistochemical features of primary renal lymphomas ( PRL) , and to discuss the diagnosis, differential diagnosis, treatment and prognosis of the tumors. Methods Clinical data of 19 patients with PRL from January 2005 to October 2014 were retrospectively analyzed. Result The 19 patients in this study, there were 11 males and 8 females and the age ranged from 37 to 85 years old (averaged 55). Patients were mainly presented with unilateral renal masses, with lumbodynia as the main symptom. 13 patients underwent nephrectomy, 6 patients underwent renal biopsy and 17 patients received CHOP or R-CHOP chemotherapy. All of them were diagnosed as non-Hodgkin’ s lymphoma, with 14 cases of diffuse large B cell lym-phoma (DLBCL) (73. 684%, 14/19), 4 cases of B cell small cell lymphoma (21. 053%, 4/19), and 1 cases of T cell lymphoma (5. 263%, 1/19). Follow-up information was available in 15 patients. 12 were still alive and survived for 1~78 months, while the other 3 were dead with 1 case who died of cerebral infarction, and survived for 3~38 months ( averaged 23 months) . Conclusion PRL is an extranodal lymphoma which is rare in kidney and is often misdiagnosed as renal carcinomas due to its nonspecific clinical manifestations. The diagnosis of PRL can be confirmed by histopathological examination, immunohistochemistry and molecular analy-sis. The majority of the lymphomas are B cell lymphomas and most of them are DLBCL. The recommended treatment is surgery com-bined with chemotherapy and the prognosis is associated with the age, clinicopathological characteristics, tumor types and treatment.

OBJECTIVETo explore the effect of occupational stress on ambulatory blood pressure.
METHODS30 male healthy workers from the refrigerator assembly line in Henan province in China were investigated. Psychosocial work conditions were measured by using the Job Demand-control Model, the Effort-reward Imbalance Model questionnaires and Occupational Stress Measurement Scale. Ambulatory blood pressure(ABP) was measured by using mobile ABP monitor. The t test was utilized to analyze the difference of parameters of ABP monitoring between different groups of occupational stress and other variables scores. The stepwise regression analysis was used to analyse the effect of occupational stress factors on parameters of ABP.
RESULTS(1) As to stressors, systolic blood pressure variability (SBPV), mean arterial blood pressure variability (MABPV) and heart rate at 30 minute after work in workers with high role conflict score were significantly higher than those in workers with low score (P < 0.05). Workers with high skill utilization score had significantly lower mean systolic blood pressure (SBP) at 30 minute after work than workers with low score (P < 0.05). Diastolic blood pressure variability (DBPV) and heart rate variability (HRV) in workers with high decision latitude score were significantly higher than those in workers with low score (P < 0.05). Workers with high job psychological demands score had significantly higher SBPV, DBPV and MABPV than workers with low score (P < 0.05). Heart rate-pressure product(RPP) and SBPV in workers with high effort score were significantly higher than those in workers with low score (P < 0.05). Workers with low rewards score had higher mean heart rate and heart rate at 30 minute after work than workers with high score (P < 0.05). (2) For personalities, workers with high work locus of control score had significantly higher mean diastolic blood pressure (DBP) and mean arterial blood pressure (MABP) than workers with low score (P < 0.05). Workers with high patience score had significantly lower mean SBP at 30 minute after work than workers with low score (P < 0.05). Heart rate at 30 minute after work in workers with high organization commitment score was significantly lower than that in workers with low score (P < 0.05). (3) Concerning buffer factors, HRV in workers with high control strategies score were significantly lower than that in workers with low score (P < 0.05). Workers with low supervisor support score had higher RPP and MABPV than workers with high score (P < 0.05). (4) In the multiple stepwise regression, daily life stress affected SBPV (R2 = 0.12) and MABPV (R2 = 0.05), depression was related to DBPV at 30 minute after work (R2 = 0.15) and SBPV (R = 0.03), mental health was predictor of MABPV (R2 = 0.07) and negative affection was predictor of heart rate at 30 minute after work (R2 = 0.24).
CONCLUSIONSOccupational stressors, personality and social support have effect on parameters of ABP. Parameters of ABP monitoring could be used to evaluate occupational stress in the field research.

Objective Sperm screening is an essential step in IVF procedures. The swim-up method, an assay on sperm motility, is used clinically to select the ideal sperm for subsequent manipulation. However, additional parameters, including acrosome reaction capability, chemotaxis, and thermotaxis are also important indicators of mammalian sperm health. To monitor both sperm motility and chemotaxis simultaneously during sperm screening, we designed and constructed a microdevice comprising a straight channel connected with a bi-branch channel that mimics the mammalian female reproductive tract. Methods The width and length of the straight channel were optimized to select the motile sperm. Cumulus cells were selectively cultured in the bi-branch channel to generate a chemoattractant-forming chemical gradient. Sperm chemotaxis was represented by the ratio of the sperm swimming towards different branches. Results The percentage of motile sperm was improved from ( 58. 5 ± 3. 8 ) % to ( 82. 6±2.9)% by a straight channel 7 mm in length and 1 mm in width. About 10% of sperm were found chemotactically responsive in our experiment, which is consistent with previous studies. Conclusion The combined evaluation of both sperm motility and chemotaxis was achieved for the first time, and the motile and chemotactically responsive sperm can be easily enriched on a lab-on-a-chip device to improve IVF outcome.

OBJECTIVETesticular mixed nonseminomatous germ cell cancer (TMNGCC) is rarely reported. This study aimed to explore the clinical symptoms, pathological characteristics and treatment methods of TMNGCC.
METHODSWe analyzed the clinical data of 1 case of TMNGCC, observed its pathological characteristics under the light microscope by histology, cytochemistry, immunohistochemistry and immune marking, and investigated the clinical features of such tumors by reviewing the relevant literature.
RESULTSThe patient presented with a chief complaint of painless testicular swelling for 3 years. Histopathological examinations revealed a tumor of papillary, fissural or adenoid structure, with large polygonal or columnar cells with one or more irregular vesicular nuclei, the nuclear membrane clear, the cytoplasm eosinophilic or basophilic, and the interstitium infiltrated by a few lymphocytes. Here are the immunohistochemical results: CD117 -, CK8-18 + +, CD30 + +, CK + + +, vimentin -, PLAP +/-, P53 +, AFP + and EMA + +. The tumor was pathologically diagnosed as teratogenic embryonic testicular cancer, and treated by radical surgery, followed by adjuvant chemotherapy according to the treatment of TMNGCC. One-year follow-up found the patient to be alive.
CONCLUSIONTMNGCC is a rare malignant tumor, mostly with unobvious clinical symptoms. Its diagnosis primarily depends on physical examination, ultrasonography, CT, and measurement of serum tumor markers; its confirmation necessitates pathological examination, and its first-choice treatment is surgical resection.

OBJECTIVETo analyze intron 1 and 22 inversions in factor VIII (FVIII) gene in hemophilia A (HA) patients and and their families and to investigate the correlation between intron inversion and FVIII antibody.
METHODSAll patients were detected FVIII: C and FVIII antibody. In addition, 81 unrelated HA patients were directly detected by multiplex PCR and long-distance PCR for intron 1 and 22 inversions in FVIII gene. Pedigree investigation for some patients were conducted.
RESULTSIn 81 unrelated HA patients, 3 severe cases were found intron 1 inversion which accounted for 4.6% of total 65 severe cases. Of the 3 cases, one was FVIII antibody positive. Two female family members of a intron 1 inversion patient were identified as one carrier and one non-carrier. Twenty five of 65 (38.5%) severe cases were found intron 22 inversion. Of the 25 cases 1 was FVIII antibody positive. Nine female members in 5 HA families which had patients with intron 22 inversion were identified as 7 carries and 2 non-carriers.
CONCLUSIONBesides intron 22 inversion, intron 1 inversion was another important molecular defect in resulting in severe HA. Intron inversion analysis can also be used for deviation rectification of experiment grouping in HA patients. Intron 1 and 22 inversions may be one of the higher risk factors for resulting in FVIII antibodies.

OBJECTIVETo detect the RNA of severe acute respiratory syndrome virus (SARS-CoV) by using reverse transcription polymerase chain reaction (RT-PCR) targeted for a two loci and a modified nested real-time RT-PCR as to improving the reliability and sensitivity of tests.
METHODSA nested RT-PCR was used for detecting one fragment of SARS-CoV RNA in oropharyngeal swabs from 3 SARS probable patients, 4 SARS suspect patients and other 27 patients with fever in Hangzhou, and the nested RT-PCR product from one SARS probable patient was sequenced. Meanwhile in these 3 SARS probable patients, other three RT-PCR methods, including a hemi-nested RT-PCR targeted for another fragment of SARS-CoV RNA, a real-time RT-PCR and a modified nested real-time RT-PCR, were employed to detect SARS-CoV RNA.
RESULTSTwo positives were found in the 3 SARS probable patients, and none positive in 4 SARS suspect patients and other 27 patients with fever, using the nested RT-PCR. The sequence of the nested RT-PCR product from one SARS probable patient was identified with the counterpart of SARS-CoV genomes published in public database. The results of the hemi-nested RT-PCR, the real-time RT-PCR and the modified nested real-time RT-PCR in the 3 SARS patients were consistent with the one of the nested RT-PCR. During detecting specimen with low copies of RNA, a weak positive signal was produced after about 35 cycles in the real-time RT-PCR, but a strong positive signal was found only after 10 cycles in the modified nested real-time RT-PCR.
CONCLUSIONIt might improve the reliability of test by employing RT-PCR targeted for two or more fragments in SARS-CoV genome. The modified nested real-time RT-PCR might have higher sensitivity than the routine real-time RT-PCR.

OBJECTIVESTo investigate the effects of astilbin on the expressions of TNF alpha and IL-10 during liver warm ischemia-reperfusion injury.
METHODSC57BL/ 6 mice were randomly divided into 4 groups (n = 8): sham-operated group (Sham), model control group(I/R), low dosage of astilbin treatment group (10 mg/kg) and high dosage of astilbin (40 mg/kg) treatment group. The treatment group mice were intraperitoneally injected with 10 or 40 mg/kg astilbin 24 hours and one hour before Ischemia, the hepatic ischemia-reperfusion model were thus established. After jn90 of min ischemia and 6 h reperfusion of the partial hepatic lobe, the expressions of TNF alpha and IL-10 in liver tissues collected from the experimental groups were detected by Western blot and semiquantitative RT-PCR.
RESULTSThe expression of TNF alpha protein in liver tissues gradually decreased in treatment groups (low and high dosages of astilbin treatment groups) as compared to the I/R model control group. Similar results were observed in the mRNA expressions of these genes as determined by semiquantitative RT-PCR (P less than 0.05 for low dosage group; P less than 0.01 for high dosage group). Compared with the I/R model control group, the expression of IL-10 was increased in both treatment groups (low dosage group P less than 0.05; large dosage group P less than 0.01).
CONCLUSIONTreatment with astilbin decreases TNF alpha expression but induces IL-10 expression in liver during warm ischemia-reperfusion injury.
