Objective:To investigate the association between Cyclin D1 and metastasis and determine the relationship between Cyclin D1 proteins expression and P21 WAF1?P53 proteins in ovarian cancer.Methods:Cyclin D1,P21 WAF1 and P53 proteins were detected from 61 ovarian carcinoma and 7 ovarian tissues without cancer by using Western blot method.Results:The positive rate of Cyclin D1 and P53 proteins expression in cases with ovarian cancer were significantly higher than those in without cancer tissues(P0.05).However, the expression of P21 WAF1 protein was correlated with clinical stages(P0.05).The expression of Cyclin D1,P53 and P21 WAF1 protein in ovarian carcinoma were related to metastasis(P

Some patients with cervix cancer occurred effusion in the uterine cavity after radiotherapy, 18 cases of them were given hysterectomy. 55.6 percent of the cases occured in 2 years after radiotherapy. The clinical manifestations were lower abdominal mass and pain. There were signs such as enlarged uterus or pelvic mass. It was found that the uterine body had malignancy in 16 cases and the cervix in 11 cases after operation. The causes of effusion were probably the adhension of upper vagina and cervix tube, secondary carcinoma and recurrence of cervix tumor. Therefore, these patients have to be treated actively, and prevention must be paid attention to.

Background Bietti crystalline dystrophy (BCD) is a congenital and autosomal recessive hereditary eye disease characterized by multiple glistening intraretinal crystals scattered over the fundus.Studies determined abnormality of fatty acid metabolism probably is associated with BCD.However,the study on the alteration of blood lipid level in BCD patients is rare.Objective This trail was to study the change of serum lipids in BCD patients.Methods A total of 50 patients with bilateral BCD and 50 matched healthy volunteers were included from November 2011 to March 2013 in Beijing Tongren Eye Center with the approval of Ethic Committee of Beijing Tongren Hospital.Written informed consent was obtained from each subject before any medial examination.Peripheral blood of 3 ml was collected from the subjects.The serum concentrations of triglyceride (TG),total cholesterol (TC),low density lipoprotein cholesterol (LDL-C) and high density lipoprotein cholesterol (HDL-C) were measured and analyzed.The examination outcome was identified based on the criteria of China Adult Dyslipidemia Prevention Guideline (Version 2007).Results Abnormality of serum lipid content was detected in 58.00％ patients (29/50),and hypertriglyceridemia and hypercholesteremia were in 34.48％ (10/29),respectively,and mixed hyperlipidaemia was in 27.59 ％ (8/29).The serum levels of TG,TC and LDL-C were (1.63± 1.19) mmol/L,(5.10±1.05) mmol/L and (3.27±0.97) mmol/L in the BCD group,which were significantly higher than (0.93± 0.33) mmol/L,(4.33 ±0.56) mmol/L,(2.63 ±0.51) mmol/L of the normal group (t =4.036,4.496,4.095,all at P=0.000).Conclusions The serum lipid levels elevate in BCD patients,which might be related to the occurrence of BCD.

Objective To analyze the CT and MRI features of splenic inflammatory myofibroblastoma (SIMF).Methods The CT and MRI images of 6 patients with SIMF were retrospectively analyzed.Results 5 cases underwent CT examination;2 cases did MRI.Six cases of SIMF were all single lesions;the average diameter was (3.9 ± 0.9) cm;the lesions were round or gourdshaped;most have clear boundaries with uneven scan density.On the MRI,the parenchymal part was slightly low signal on T1WI,inhomogeneous hypointensity on T2WI,or high signal on T2WI.After CT or MRI enhancement,lesions were progressively enhanced.Correct preoperative diagnosis was established in only 1 patient.Conclusion In this study,all SIMF cases present as single lesion.The circular appearance and clear boundaries are in common.Asymptotic intensification with map-unenhanced regions is the main enhancement feature.

Background: Blackened intestines in slaughtered pigs have been commonly observed in China in recent years. However, no cause has been reported. Objectives: We attempted to determine whether the blackening of the pig intestine was related to an excess of copper (Cu) in their feed. Methods: In this study, we observed and collected porcine intestines in small- and large-scale pig slaughterhouses in Shandong province from May to October 2018. Twelve types of metal ions were detected in the black intestinal samples. Results: The Cu level in the intestine samples was mostly higher than the Chinese national limit for food. Further study showed that Cu supplementation in most commercial porcine feed also exceeded the national standard. An animal model (mouse) that could mimic the intestinal blackening in pigs was established. Compared to control mice, Cu accumulated in the liver and intestines of mice fed an excessive Cu level, confirming the excessive Cu in the feed may be considered the major cause of blackened porcine intestines. Microscopic examination revealed that black intestines had many particles containing Cu in the lamina propria of the intestinal mucosa, and the intestinal mucosal epithelial cells showed degeneration and necrosis. Conclusions In conclusion, overuse of Cu in animal feed can lead to animal poisoning and Cu accumulation in animal products. Such overuse not only harms the health of livestock but can also affect public health.

Background: Pseudorabies, also known as Aujeszky's disease, is caused by the pseudorabies virus (PRV) and has been recognized as a critical disease affecting the pig industry and a wide range of animals around the world, resulting in great economic losses each year. Shandong province, one of the most vital food animal-breeding regions in China, has a very dense pig population, within which pseudorabies infections were detected in recent years. The data, however, on PRV epidemiology and coinfection rates of PRV with other major swine diseases is sparse. Objectives: This study aimed to investigate the PRV epidemiology in Shandong and analyze the current control measures. Methods: In this study, a total number of 16,457 serum samples and 1,638 tissue samples, which were collected from 362 intensive pig farms (≥ 300 sows/farm) covered all cities in Shandong, were tested by performing enzyme-linked immunosorbent assay (ELISA) and polymerase chain reaction (PCR). Results: Overall, 52.7% and 91.5% of the serum samples were positive for PRV-gE and -gB, respectively, based on ELISA results. In addition, 15.7% of the tissue samples were PCR positive for PRV. The coinfection rates of PRV with porcine circovirus type 2 (PCV2), porcine reproductive and respiratory syndrome virus, and classical swine fever virus were measured; coinfection with PCV2 was 35.0%, higher than those of the other two viruses. Macroscopic and microscopic lesions were observed in various tissues during histopathological examination. Conclusions The results demonstrate the PRV prevalence and its coinfection rates in Shandong province and indicate that pseudorabies is endemic in pig farms in this region. This study provides epidemiological data that can be useful in the prevention and control of pseudorabies in Shandong, China.
