Foodbome viruses are defined to be viruses that can lead to human diseases through food. In accordance with the different origin, foodborne viruses can be divided into two kinds: intestinal viruses and zoonotic viruses. The former include those viruses that can be transmitted to person via fecal-orally route. The latter include those zoonotic viruses that chiefly transmitted to person through livestock and poultry products. This paper expounds foodborne viruses categories, biology nature, epidemiology character, and study circumstance, and clarifies the molecular biological methods and problems on the base of the polymerase chain reactions, and presents the development direction and application perspective of the foodbome viruses study.

OBJECTIVETo investigate the role of endoplasmic reticulum stress in the apoptosis of testicular germ cells in hyperlipidemic rats.

METHODSWe randomly assigned 42 four-week-old male Wistar rats into a normal control group (n = 12) and a high-fat group (n = 30) to be fed on a normal diet and a high-fat diet, respectively, for 10 weeks. Then we measured the concentrations of triglyceride (TG) and total cholesterol (TC) in the serum using an automatic biochemistry analyzer, detected the apoptosis of testicular germ cells by TUNEL staining, and determined the protein and mRNA expressions of GRP78 and. caspase-12 in the testis tissue by immunohistochemistry and RT-PCR, respectively.

RESULTSThe concentrations of TG and TC were significantly increased in the animals of the high-fat group ([3.00 ± 0.92] and [3.04 ± 0.39] mmol/L) as compared with the control rats ([1.43 ± 0.41] and [1.55 ± 0.23] mmol/L) (P < 0.01), and so was the apoptosis index of the testicular germ cells ([37.17 ± 2.74]% vs [5.16 ± 0.81]%, P < 0.01). The high-fat group, in comparison with the control, also showed remarkably upregulated protein and mRNA expressions of GRP78 (0.32 ± 0.03 and 0.86 ± 0.05 vs 0.19 ± 0.01 and 0.37 ± 0.03, P < 0.01) and caspase-12 (0.34 ± 0.02 and 0.87 ± 0.01 vs 0.12 ± 0.01 and 0.34 ± 0.03, P < 0.01) in the testis tissue.

CONCLUSIONThe apoptosis of testicular germ cells is increased in hyperlipidemic rats, which may be attributed to endoplasmic reticulum stress.

OBJECTIVETo study clinical effects of a new internal fixation by using a cable through the bone and Kirschner with a hole in the tail, for the treatment of patellar fractures.

METHODSFrom May 2012 to July 2013, thirty-four patients with patellar fractures were treated with cable through the bone and Kirschner with a hole in the tail. All the patients had close fracture,including 12 transverse fractures and 22 comminuted fractures. There were 18 males and 16 females, ranging in age from 26 to 81 years old, with an average of (46.0 ± 3.0) years old. After open reduction, two appropriate length of Kirschner with a hole in the tail were driven into the patella as perpendicular to the fracture line or the major fragments as possible. A transverse bone tunnel was then drilled with a Kirschner at one side of the patella. Then the cable, which was successively pulled through the bone tunnel and the hole of Kirschner, was crossed in a figure-eight over the anterior of the patella, tightened and fixated by special instruments. The Kirschner was clipped off on the edge of the hole. If it was a comminuted fracture, another cable was used to fasten the patella with cerclage. Postoperative evaluation was based on Bostman.

RESULTSAll the patients were followed up, and the duration ranged from 12 to 26 months, with a mean of (16.0 ± 2.0) months. Fractures healed in all the cases without such complications as infection, loosening of Kirschner and cable loop, and skin irritation. According to the Böstman score system, 33 cases got an excellent result, and 1 good.

CONCLUSIONThe cable through the bone and Kirschner with a hole in the tail is a simple, stable and effective method for the treatment of patellar fractures, especially the transverse fractures, with earlier knee exercise and fewer complications.

AIM:To characterize the effect of estradiol on proliferation,differentiation and extracellular matrix(ECM) accumulation in stromal cells through regulation of BPH-1 paracrine.METHODS:BPH-1 cells were stimulated with different concentrations of estradiol.Conditioned media(CM) were harvested and their effects on stromal cell cultures were tested.Cell proliferation was determined by MTT assay.mRNA of smoothelin,fibronectin,collagen Ⅳ and transforming growth factor ?1(TGF-?1) were analyzed by real-time RT-PCR.Western blotting was used to determine smooth muscle myosin heavy chain(SMMHC).ELISA and radioimmunoassay were respectively used to measure fibronectin,TGF-?1 and collagen Ⅳ protein expressions.RESULTS:Estrodiol stimulated the expression and secretion of TGF-?1 in BPH-1 cells.The proliferation of stromal cells increased when they were cultured with CM harvested from estrogen treated BPH-1 cells.The mRNA levels of collagen Ⅳ and smoothelin increased in stromal cells treated with CM from BPH-1 cells.The results of radioimmunoassay also showed that the collagen Ⅳ protein level up-regulated in the supernatants and cell extracts of CM-treated stromal cells.A neutralizing antibody to TGF-?1 inhibited the stimulation of collagen Ⅳ and SMMHC by BPH-1 CM.The expression of fibronectin was only marginally changed in stromal cells cultured in the presence of BPH-1 CM.CONCLUSION:The BPH-1 cells increase ECM accumulation and differentiation of stromal cells through TGF-?1.Estradiol stimulate differentiation of stromal cells by induction of TGF-?1 expression.Estradiol stimulate proliferation by influencing the factors secreted from prostatic epithelial cells.

Objective This study was to assess the three-dimensional gross tumor volume(GTV)motion of lung cancer caused by respiration using four-dimensional computed tomography(4DCT),and to analyze the influenee factors.Methotis Four-DCT scans of 22 lung focuses in 21 patients with lung cancer were analyzed.The gross tumor volume was contoured in all 10 respiration phases of 4DCT scans.The changes in volume of GTV,the 3D motion of the centroid,boundary of GTV and the 3D spatial motion vectors were calculated and the irdluenee factors were analyzed.Results The average change in volume of GTV was+14.3%(0.2%.42.5%)/-8.4%(0.4%-38.6%),the average movement amplitude of GTV centroid and GTV boundary were(0.18±0.12)cm,(0.20±0.16)cm,(0.53±0.59)cm and(0.42±0.23)cm,(0.41±0.22)cm,(0.57±0.70)cm in medio-lateral,vertro-dorsal,cranio-caudal(CC) direction,respectively.The CC movement was larger than other directions(Z=-2.12,P=0.034;Z:-2.10,P=0.035),and no significant difference was observed in 3D motion of GTV boundary(Z=-0.81.P=0.417;Z=-0.86,0.391).The CC motion of GTV eentroid in lower lobe was larger than that in upper lobe[(0.87±0.64)and(0.35±0.49)cm,(t=-2.12,P=0.047)],and no significant difference was found in other directions[(0.23±0.10)and(0.19±0.18)em(t=-0.49,P=0.629),(0.21±0.13)and(0.17±0.11)cm(t=0.76,P=0.460)].There was no correlation of the 3D movement and 3D spatial motion vector of GTV to the volume of GTV(r=-0.306,-0.062,-0.279,-0.300;P=0.189,0.796.0.234,0.199).Conclusions GTV motion of patients with lung cancer is individual,the CC movement is the moat obvious,using 4DCT to assess is comparatively accurate.The motion amplitude of lower lobe focuses is larger.No significant correlation of the GTV motion to the volume was observed.Larger sample study is needed to analyze the influence of adjacency to the GTV motion.

Selectable marker genes that usually encode antibiotic or herbicide resistances are widely used for the selection of the transgenic plants, but they become unnecessary and undesirable after transformation selection. An important strategy to improve the transgenic plants' biosafety is to eliminate the marker genes after successful selection. In the FLP/frt site-specific system of the 2 microm plasmid of Saccharomyces cerevisiae, the FLP enzyme efficiently catalyzes recombination between two directly repeated FLP recombination target (frt) sites, eliminating the sequence between them. By controlled expression of the FLP recombinase and specific allocation of the frt sites within transgenic constructs, the system can be applied to eliminate the marker genes after selection. Through a series of procedures, the plant FLP/frt site-specific recombination system was constructed, which included the frt containing vector pCAMBIA1300-betA-frt-als-frt and the FLP expression vector pCAMBIA1300-hsp-FLP-hpt. The FLP recombinase gene was introduced into transgenic (betA-frt-als-frt) tobacco plants by re-transformation. In re-transgenic plants, after heat shock treatment, the marker gene als flanked by two identical orientation frt sites could be excised by the inducible expression of FLP recombinase under the control of hsp promoter. Excision of the als gene was found in 41% re-transgenic tobacco plants, which indicated that this systerm could make a great contribution to obtain the marker free transgenic plants.
