Objective To investigate behavioral and endocrinal changes following the conflict-related stress. Method Male SpragueDawley rats were exposed to stressors using Vogel conflict test. Body weight and behavioral responses in open field test were investigated during the whole procedure. Serum corticosterone level was analyzed using immunoassay. Results Compared with the control, the rats of the 1-week, 2-week and 4-week stressed group showed significantly decreased body weight. There was increasing tendency or significant difference in locomotion between the 1 -week, 2-week and 4-week stressed group and their control. And the hormone levels for the stressed animal were reliably high. Conclusions The increased locomotion, and high corticosterone level and reduced body weight in stress animal,was consistent with the features of anxiety-like disorders. Furthermore, the behavioral and endocrine changes produced by conflict-related stress could maintain a long time. The conflictrelated stress paradigm may be used as psychological stress animal mode in the future.

Objective To investigate the effect of olmesartan medoxomil on osteoprotegerin and serum inflammatory factor expression in atherosclerosis model rat.Methods From 2015 April in Jiangsu Institute of schistosomiasis control,24 Sprague-Dawley rats were randomly divided into the following three groups:the control group was fed with standard food,the model group was fed with high fat diet based on standard food(normal food +2％ cholesterol +5％ goat fat +0.2％ acid +7×105 IU/(kg·d) Vitamin D3),and the olmesartan group was given 3 mg/(kg·d) olmesartan gavage daily on the basis of high fat diet.On the fourth week of experiment the level of serum high sensitivity C reactive protein and serum lipids include total cholesterol,low density lipoprotein,high density lipoprotein and triglyceride were detected.The structure and changes of aortic pathology was observed.The expression of osteoprotegerinin in aortic was detected by immunohistochemistry staining and Western blot.Results Within the model group,the level of serum lipid and high-sensitivity C reactive protein increased significantly,endometrial thickness,intima-to-media thickness ratio and osteoprotegerin expression in aorta was significantly higher than that of normal group,the difference was statistically significant(P<0.05).The serum high density lipoprotein increased significantly,the level of other serum lipids and high sensitive C reaction protein decreased significantly,endometrial thickness,intima-to-media thickness ratio and osteoprotegerin expression in aorta of the olmesartan treated rats were significantly lower than those of model animals,the difference was statistically significant(P<0.05).Conclusion Olmesartan may suppress the development of atherosclerosis in model rats by decreasing the expression of osteoprotegerin and the level of serum inflammatory cytokines.

To generate a mWAP-hLF hybrid locus that the transcription of human lactoferrin (hLF) genomic sequence is directed by the up & down stream regulatory sequence of murine whey acidic protein (mWAP) gene locus, we describe here a successive three-step 'Gap-repair' method. First, a gap-repair vector based on pBR322 vector backbone by inserting six joint homologous arms was constructed. Then using 'Gap-repair 'method mediated by Red recombination system of lambda-prophage in Escherichia coli, in the first step, the 8 kb 3' flanking region of the mWAP gene was subcloned from the Bacterial artificial chromosome which harbors the mWAP gene locus(mWAP BAC) into the gap-repair vector; in the second step, the 29 kb hLF genomic sequence from the ATG code to the TAA code was subcloned from the hLF BAC; in the third step, the 12 kb 5' flanking region of the mWAP gene was subcloned from the mWAP BAC. Finally, all these three DNA fragments were automatically combined together without any gap in the gap-repair vector, and a 49 kb mWAP-hLF hybrid locus that the hLF genomic sequence was flanked by the 5' & 3' flanking region of mWAP gene locus was constructed. The result was confirmed by PCR, restriction enzyme digestion and sequencing. Our method provide a new way for the construction of large mammary-gland expression vector.

Objective To find the effects of varus degree on the early metabolic changes of the lateral compartment cartilage in knees with medial unicompartmental osteoarthritis by detecting glycosaminoglycan (GAG) in varus knees.Methods From June 2016 to December 2017,twenty middle-aged volunteers without osteoarthritis or coronal deformities were recruited as the control group.Sixty patients diagnosed as medial unicompartmental osteoarthritis were recruited as the osteoarthritis group.The patients were further divided into four groups according to the degrees of varus angle,namely 2°-5° varus group,5°-10° varus group,10°-15° varus group and ＞15° varus group with 15 patients in each group.Delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC) was performed in all participants.The dGEMRIC indices (T1Gd) representing GAG content were calculated in the weight-bearing femoral cartilage (wbFC),the posterior non-weight-bearing femoral cartilage (pFC),the lateral femoral cartilage (FC,wbFC+pFC) and the tibial cartilage (TC) in the lateral compartment by using Matlab 7.1 and MRIMapper software.Results T1Gd of wbFC,pFC,FC and TC were 400.3±51.5 ms,393.6±57.9 ms,397.5±52.3 ms and 448.6±62.5 ms in the control group,391.8±41.5 ms,407.2±43.8 ms,400.1±37.8 ms and 461.3±41.6 ms in 2°-5° varus group and 386.9±57.1 ms,401.3±73.5 ms,397.7±59.6 ms and 438.9±42.8 ms in 5°-10° varus group.There was no significant difference among the above three groups in T1Gd in any of the analyzed cartilage regions (P＞0.05).In 10°-15° varus group,T1Gd of wbFC,pFC,FC and TC were 380.1±45.5 ms,385.5±76.6 ms,384.0±53.5 ms and 400.2±43.8 ms,respectively.Although T1Gd of wbFC,pFC and FC in 10°-15° varus group were similar with that in the control group,2°-5° varus group and 5°-10° varus (P＞0.05),T1Gd of TC in 10°-15° varus group decreased significantly (P＜0.05).In addition,T1Gd of wbFC,pFC,FC and TC in ＞15° varus groupwere 327.7±54.3 ms,340.1±33.0 ms,334.9±36.0 ms and 363.6±48.6 ms,respectively.T1Gd of all regions of interest in ＞15° varus group were significantly lower than that informer four groups (P＜0.05).Conclusion In medial unicompartmental knee osteoarthritis,there is a relationship between varus degree and GAG content of the lateral compartment cartilage.If varus angle ≤10°,the GAG content of the lateral compartment cartilage was similar with the similar aged subjects without osteoarthritis.If varus angle ＞ 10°,GAG content of the lateral compartment decreases significantly.

OBJECTIVETo understand the transmission mode of human infection with avian influenza A (H7N9) virus.

METHODSField epidemiological investigation was conducted for a family clustering of human infection with H7N9 virus in Hengxian county, Guangxi Zhuang Autonomous Region in February 2014. Two patients and their 82 close contacts were surveyed. The samples collected from the patients, environments and poultry were tested by using real time reverse transcriptase-polymerase chain reaction (rRT-PCR), and the samples from patients were used for virus isolation. The samples from 5 close contacts were tested with RT-PCR. The clinical data, exposure histories of the patients and the detection results of the isolates and their homology were analyzed.

RESULTSPatient A became ill 4 days after her last exposure to poultry in Zhongshan, Guangdong province, and returned to her hometown in Hengxian 2 days after onset. Patient B was patient A's 5 years old son, who had no known exposure to poultry but slept with patient A for 4 days. He developed symptoms 4 days after last contact with his mother. Two strains of H7N9 virus were isolated from the two patients. The 2 isolates were highly homogenous (almost 100%) indicated by gene sequencing and phylogenetic tree. None of the other 81 close contacts developed symptoms of H7N9 virus infection.

CONCLUSIONPatients B was infected through close contact with patient A, indicating that avian H7N9 virus can spread from person to person, but the transmissibility is limited and non-sustainable.

BACKGROUND: Hypertension is associated with stroke-related mortality. However, the long-term association of blood pressure (BP) and the risk of stroke-related mortality and the influence path of BP on stroke-related death remain unknown. The current study aimed to estimate the long-term causal associations between BP and stroke-related mortality and the potential mediating and moderated mediating model of the associations. METHODS: This is a 45-year follow-up cohort study and a total of 1696 subjects were enrolled in 1976 and 1081 participants died by the latest follow-up in 2020. COX proportional hazard model was used to explore the associations of stroke-related death with baseline systolic blood pressure (SBP)/diastolic blood pressure (DBP) categories and BP changes from 1976 to 1994. The mediating and moderated mediating effects were performed to detect the possible influencing path from BP to stroke-related deaths. E value was calculated in the sensitivity analysis. RESULTS: Among 1696 participants, the average age was 44.38 ± 6.10 years, and 1124 were men (66.3%). After a 45-year follow-up, a total of 201 (11.9%) stroke-related deaths occurred. After the adjustment, the COX proportional hazard model showed that among the participants with SBP ≥ 160 mmHg or DBP ≥ 100 mmHg in 1976, the risk of stroke-related death increased by 217.5% (hazard ratio [HR] = 3.175, 95% confidence interval [CI]: 2.297-4.388), and the adjusted HRs were higher in male participants. Among the participants with hypertension in 1976 and 1994, the risk of stroke-related death increased by 110.4% (HR = 2.104, 95% CI: 1.632-2.713), and the adjusted HRs of the BP changes were higher in male participants. Body mass index (BMI) significantly mediated the association of SBP and stroke-related deaths and this mediating effect was moderated by gender. CONCLUSIONS In a 45-year follow-up, high BP and persistent hypertension are associated with stroke-related death, and these associations were even more pronounced in male participants. The paths of association are mediated by BMI and moderated by gender.
