Smoke water and distillation liquid were used to treat the seeds of Trichosathes kirilowii and to study the effects of smoke water and distillation liquid on the seed germination and seedling growth of T. kirilowii. The results showed that germination rate, germination index and germination vigor of T. kirilowii all were significantly improved with the treatment of SW and DL treatment. The activity of α-amylase were significantly increased with the treatment of SW and DL at 1:2,000. SW and DL treatment showed no significant effects on the activity of SOD. The activity of POD were markedly enhanced under the treatment of SW (1:000) and DL (1:2,000). CAT activity were increased with the treatment of SW and DL at 1:2,000 while were inhibited by SW and DL at 1:500. Seedling height and root length were increased with the treatment of SW and DL (1:1,000, 1:2,000). SW and DL treaments improved the content of chlorophyll, and moreover with the concentration of SW and DL, the stimulatory were also increased. This work demonstrated that smoke water and diatillation liquid at 1:2,000 could stimulate the seed germination and seedling growth of T. kirilowii, and it provided the references for the study of seed germination technology.

Objective To study the association of liver fat content (LFC) with insulin resistance and β cell function. Methods One hundred and nine subjects including 31 cases with impaired glucose regulation (IGR), 31 newly diagnosed type 2 diabetes (NT2DM) and 47 normal controls (NC) with normal metabolic parameters were involved in the study. LFC was measured by 1H magnetic resonance spectroscopy (1H MRS) and the insulin resistance and β cell function were evaluated by oral 75 g glucose tolerance test. Results (1 ) LFCs were3.83% (2.35% ～7.59% ) ,12. 82% (8.10%～21.37%), and 21.99% (11.89%～34.43%), being progressively raised in the respective NC, IGR, NT2DM groups(P<0.01). (2) The subjects were divided into four subgroups according to LFC Quartile: Quartile 1 (LFC<4. 04% ) , Quartile 2(4. 04% ≤LFC<9. 77% ), Quartile 3 (9.77% ≤LFC<20.78% ) ,and Quartile 4( LFC≥20.78% ). Homeostasis model assessment of insulin resistance index (HOMA-IR) values were elevated significantly and progressively starting from Quartile 2(P<0. 01). (3) Insulin from 0 to 30 min ( △I30), the ratio of insulin from 0 to 30 min to glucose from 0 to 30 min ( △I30/ △G30) , C peptide from 0 to 30 min (△CP30) had a trend of increase in Quartile 2,then trended to decrease in Quartile 3. In Quartile 4, △CP30 and △I30/△G30 sharply decreased (P<0.05 or P<0.01). The ratio of C peptide from 0 to 30 min to glucose from 0 to 30 min ( △CP30/△G30) began to decrease from Quartile 3 (P<0. 05). The ratio of area under curve of C peptide to area under curve of glucose (CPAUC/GAUC) was significantly decreased from Quartile 3(P<0.05). From Quartile 3,glucose level became abnormally elevated to impaired fasting glucose and impaired glucose tolerance (P<0.01). (4) LFC was positively correlated with HOMA-IR (rs =0. 618 ,P<0.01), but was negatively correlated with △CP30(rs =-0.282), △CP30/△G30(rs = -0. 404), and CPAUC/GAUC(rs = -0. 308,all P<0.01). (5) Stepwise regression analysis demonstrated that LFC was the strongest predictor of HOMA-IR. Conclusions When LFC accumulated to 4% , insulin resistance occurred and the early phase of insulin secretion was compensatively increased. As the LFC further accumulated to 10% , both the early phase as well as β cell function in whole were deteriorated, and hyperglycemia developed.

Objective To investigate the effects of trichostatin A(TSA)on the mice model of collagen induced arthritis(CIA).Methods Mice model of rheumatoid arthritis(RA)was induced in DBA/1 mice with type Ⅱ collagen.Paws were scored for histological severity of arthritis.The severity of inflammation of mouse joint was evaluated by histological examination.Real-time PGR was used to determine the cytokine mRNA expression.Cytokine production was measured by ELISA from serum,spleen cell culture or dendritic cell and T cell co-culture supematant.T cell proliferation was examined by MTT method.Results TSA can significantly suppress the severity of the arthritis in CIA.IFN-γ was elevated in CIA mice,but was inhibited significantly by TSA introduced either at the same time with immunization or at the onset of manifestation of arthritis.Collagen specific T cell proliferation was significantly suppressed by introduction of TSA.Increased level of IL-4 by T cells was observed in TSA treated group compared to that of control group.Conclusion IL-4 level was increased and played a critical role in the protective effects of TSA in CIA.TSA suppresses the progress of CIA by regulates the balance of Th1/Th2 differentiation.

Objective: To investigate the factors affecting depression and anxiety symptoms among the elderly, so as to provide the basis for promoting mental health among the elderly. Methods: The elderly aged 60 years and above in Ningbo City, Zhejiang Province were recruited using the multistage stratified random sampling method from June to August 2022, and demographic information, lifestyle and self-rated health status were collected by questionnaires. The symptoms of depression and anxiety were assessed by the Patient Health Questionnaire-9 (PHQ-9) and the Generalized Anxiety Disorder-7 (GAD-7), respectively. The presence of depressive and anxiety symptoms was determined when both the PHQ-9 score and the GAD-7 score were 10 points and higher. Factors affecting depressive and anxiety symptoms were identified using a multivariable logistic regression model. Results: A total of 7 771 individuals were surveyed, including 3 490 males (44.91%) and 4 281 females (55.09%), and had a mean age of (72.11±6.79) years. The prevalence of depression and anxiety symptoms was 2.05%. Multivariable logistic regression analysis identified residence (urban area, OR=0.316, 95%CI: 0.201-0.498), sedentary duration (<3 h/d, OR=0.349, 95%CI: 0.232-0.525; 3-5 h/d, OR=0.458, 95%CI: 0.313-0.671), physical activity (≥3 times/week, OR=0.551, 95%CI: 0.373-0.815), sleep quality (poor, OR=2.491, 95%CI: 1.738-3.571), social isolation (OR=1.688, 95%CI: 1.148-2.481) and self-rated health (poor, OR=5.857, 95%CI: 3.547-9.671; normal, OR=1.903, 95%CI: 1.234-2.937) as the influencing factors for depression and anxiety symptoms among the elderly. Conclusion The prevalence of depression and anxiety symptoms among the elderly is associated with residence, sedentary duration, sleep quality, physical activity, social interactions and self-rated health status.

Trichosanthes kirilowii has been widely cultivated as its medicinal use, health care and food value. Drought resistance of seedlings is an important feature in breeding. Seeds of two T. kirilowii strains were used to research the difference of surface ultrastructure characteristic and drought resistance. Scanning electron microscope was used to identify the surface ultrastructure characteristic of seeds and PEG was used to simulate drought stress. The seeds germination rate, MDA content, chlorophyll content and the antioxidant enzymes activity were measured under the drought stress. The results showed that the seed surface colour of KXY-001 was lighter than that of KXY-005. The testa cobwebbing of KXY-001 was more intensive than that of KXY-005. The germination rate of KXY-001 was higher than that of KXY-005 under drought stress. The MDA content was increased and the chlorophyll content was decreased with the increasing of drought degree. The SOD activity of KXY-001 was higher than that of KXY-005, while the activity of POD and CAT was also increased firstly and decreased later. Surface reticulate of seeds and hilar traits can be used as identification points to identify the investigated strains. SOD and POD are activated to resist drought in T. kirilowii seedlings and the drought resistance of KXY-001 is superior than that of KXY-005.

The aim of this study is to establish the method of loop-mediated indirect PCR assay for detection of Reproductive and Respiratory Syndrome Virus (PRRSV) infection and differentiation of highly pathogenic PRRSV (HP-PRRSV) and lowly pathogenic PRRSV (LP-PRRSV). Based on the alignments of ORF2 gene sequences and ORFla gene sequences of PRRSV Chinese isolates deposited in GenBank, two pairs of specific probes were designed and labeled to both ends of the soybean Lectin gene fragment by PCR, respectively. The probe-labeled soybean Lectin genes were used to be reporter genes for detection and differentiation of PRRSV. After one round strand displacement reaction, the reporter genes were amplified by reverse PCR. The specific PCR products were 193bp, 355bp for HP-PRRSV and 193bp, 442bp for LP-PRRSV, respectively. The method could detect 5. 6 TCID50/mL LP-PRRSV RNA and 18 TCIDs0/ mL HP-PRRSV RNA, and co-infection did not affect detection sensitivity. No amplification was observed with other porcine originated pathogens including CSFV, PPV, PRV, PCV2, ETEC and Haemophilus parasui. Twenty clinical samples were used for comparative testing with conventional PCR. Fourteen samples were found positive for PRRSV by the loop-mediated indirect PCR, of which 4 were LP-PRRSV, 9 HP-PRRSV and 1 LP/HP-PRRSV co-infection, consistent with the conventional PCR test results. In conclusion, the loop-mediated indirect PCR is a simple, rapid, sensitive and specific etiologic diagnosis tool, and suitable for the differential diagnosis of HP/LP-PRRSV, especially for identification of mixed infection of HP/LP-PRRSV.
