Depression status of elderly patients with metabolic syndrome in three provinces of China / 中华流行病学杂志

Objective: To understand the depression status and its influencing factors in elderly patients with MS in China and to explore the correlation between various components of elderly MS and depression. Methods: This study is based on the "Prevention and Intervention of Key Diseases in Elderly" project. We used a multi-stage stratified cluster random sampling method to complete 16 199 elderly aged 60 years and above in 16 counties (districts) in Liaoning, Henan, and Guangdong Provinces in 2019, excluding 1 001 missing variables. Finally, 15 198 valid samples were included for analysis. The respondents' MS disease was obtained through questionnaires and physical examinations, and the respondents' depression status within the past half month was assessed using the PHQ-9 Depression Screening Scale. The correlation between elderly MS and its components and depression and its influencing factors were analyzed by logistic regression. Results: A total of 15 198 elderly aged 60 years and above were included in this study, with the prevalence of MS at 10.84% and the detection rate of depressive symptoms in MS patients at 25.49%. The detection rates of depressive symptoms in patients with 0, 1, 2, 3, and 4 MS abnormal group scores were 14.56%, 15.17%, 18.01%, 25.21%, and 26.65%, respectively. The number of abnormal components of MS was positively correlated with the detection rate of depressive symptoms, and the difference between groups was statistically significant (P<0.05). The risk of depression symptoms in patients with MS, overweight/obesity, hypertension, diabetes, and dyslipidemia was 1.73 times (OR=1.73, 95%CI:1.51-1.97), 1.13 times (OR=1.13, 95%CI:1.03-1.24), 1.25 times (OR=1.25, 95%CI:1.14-1.38), 1.41 times (OR=1.41, 95%CI:1.24-1.60), 1.81 times (OR=1.81,95%CI:1.61-2.04), respectively, more than those without the disease. Multivariate logistic regression analysis showed that the detection rate of depressive symptoms in patients with sleep disorders was higher than that with normal sleep (OR=4.89, 95%CI: 3.79-6.32). The detection rate of depressive symptoms in patients with cognitive dysfunction was 2.12 times higher than that in the average population (OR=2.12, 95%CI: 1.56-2.89). The detection rate of depressive symptoms in patients with impaired instrumental activities of daily living (IADL) was 2.31 times (OR=2.31, 95%CI: 1.64-3.26) higher than that in the average population. Tea drinking (OR=0.73, 95%CI: 0.54-0.98) and physical exercise (OR=0.67, 95%CI: 0.49-0.90) seemed to be protective factors for depression in elderly MS patients (P<0.05). Conclusions: Older patients with MS and its component abnormalities have a higher risk of depression than the average population. Sleep disorders, cognitive impairment, and IADL impairment are important influencing factors for depression in elderly MS patients, while tea drinking and physical exercise may help to reduce the risk of the disease.

Identification of Panax ginseng and Panax quinquefolius by Mitochondrial Cox Ⅱ Intron / 中国实验方剂学杂志

Objective:To develop a simple and accurate method for molecular authentication of Panax ginseng and P. quinquefolius.Method:The mitochondrial cox Ⅱ sequences of P. ginseng and P. quinquefolius were amplified by polymerase chain reaction（PCR）with universal primers. PCR products of the two species were sequenced in both directions, and sequence alignments were conducted for intron length polymorphisms exploitation. Multiplex PCR was established for the identification of P. ginseng and P. quinquefolius with their specific primers，which were designed respectively based on their insertion sequences. And the limit of detection of the multiplex PCR was also determined.Result:The insertion/deletion sequences were exploited in mitochondrial cox Ⅱ. Under the established multiplex PCR assay，P. ginseng generated a 729 bp specific band, while P. quinquefolius yielded a 141 bp specific amplicon，and the mixture of the two species yielded both 729 bp and 141 bp fragments. The established multiplex PCR assay could detect 0.1% of intentional adulteration of P. quinquefolius into P. ginseng, with down to 0.001 ng of genomic DNA.Conclusion:The established multiplex PCR assay can accurately identify P. ginseng and P. quinquefolius from different sources, without the optimization of reaction system and the introduction of additional mismatches，so as to provide a new molecular marker method for identifying botanical origin of P. ginseng and P. quinquefolius.

Objectiye To observe the prevalence of prolonged seizures and the changes of biochemical markers of myocardial injury in patients with prolonged seizures after modified electroconvulsive therapy(MECT).Methods Patients treated with MECT or simulated ECT were divided into three groups.Group Ⅰ , 26 patients,experienced at least one prolonged seizure after MECT;group Ⅱ,41 selected patients, had not prolonged seizures at all during a course of MECT treatments and group Ⅲ, 31 patients, received simulated ECT.Biochemical markers of myocardial injury, including phosphocreatine kinase (CK), MR isoenzyme of phosphocreatine kinase (CK-MB), lactate dehydrogenase ( LDH ), α-hydroxybutyrate dehydrogenase ( α-HBDH ) and cardiac troponin (cTnT) ,were measured immediately, 3 hours later and on the following day after the first prolonged seizure for group Ⅰ ,the same time points as group Ⅰ after the first treatment of MECT for group Ⅱ , immediately after simulated ECT for group Ⅲ.These indexes were compared between the patients of three groups.Results The positive rate ofcTnT was 30.8%(8/26) and 17.1% (7/41)in group Ⅰ and Ⅱ respectively, but no difference was found(P＞0.05 ).CK measured immediately after MECT in patients of group Ⅰ was significantly higher than that of group Ⅲ(P ＜ 0.05 ).CK-MB (immediately), LDH ( immediately and 3 hours later) and α-HBDH ( immediately, 3 hours later and on the following day) in patients of group Ⅰ were significantly higher than those of group Ⅱ and Ⅲ measured after MECT or simulated ECT(P＜0.05 ).Conclusion More attention should be paid that absolute or relative hypoxemia may lead to minor myocardial injury.

Effects of Ganoderma lucidum spores on sialoadenitis of nonobese diabetic mice / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Sjögren syndrome (SS) is a systematic autoimmune disease, on which traditional therapeutic agents show limited effect. More effective agents with longer-lasting and fewer side effects are needed in the clinic. The aim of this study was to investigate the effects of Ganoderma lucindum spores (GLS) on sialoadenitis of nonobese diabetic (NOD) mice.</p><p><b>METHODS</b>Thirty-two female NOD mice were assigned randomly into 4 groups: low-dose GLS-treated (L-GLS) group and high-dose GLS-treated (H-GLS) group, a dexamethasone group, and a normal saline (NS) control group. Stimulated total saliva flow rate (STFR), area of lymphocytic infiltration in submandibular glands and ratios of CD4(+) and CD8(+) T lymphocytes and B lymphocytes in peripheral blood as well as apoptosis of these subsets and serum IgG level were tested after 10 weeks of treatments. Differences among the groups were analyzed by one-way analysis of variance (ANOVA), Student-Newman-Keuls Test (SNK) was used between each two groups and a P < 0.05 was considered statistically significant.</p><p><b>RESULTS</b>STFR of the high-dose GLS group increased significantly after a 10-week treatment compared with those of the NS control group (P < 0.05). The incidence of sialoadenitis in GLS-treated NOD mice groups showed no significant difference compared with the control group (P > 0.05), but the area of lymphocytic foci in both the H-GLS and L-GLS groups decreased significantly to 50% of the NS control group (P < 0.05); the ratio of CD4(+)/CD8(+) T lymphocytes and apoptosis of B lymphocytes of NOD mice with sialoadenitis were less and apoptosis of CD4(+) and CD8(+) T lymphocytes were significantly increased compared with the control group (P < 0.05). After pretreatment with H-GLS before sialoadenitis onset, the ratio of CD4(+)/CD8(+) T lymphocyte and the serum IgG levels of NOD mice decreased significantly (P < 0.05).</p><p><b>CONCLUSIONS</b>Pretreatment with H-GLS can relieve symptoms of sialoadenitis in NOD mice. GLS has some protective effects on sialoadenitis in NOD mice through increasing STFR and decreasing the area of lymphocytic foci by regulating the ratio of CD4(+)/CD8(+) T and apoptosis of B lymphocytes.</p>

Modelling and simulation of signal transductions in an apoptosis pathway by using timed Petri nets.

This paper first presents basic Petri net components representing molecular interactions and mechanisms of signalling pathways, and introduces a method to construct a Petri net model of a signalling pathway with these components. Then a simulation method of determining the delay time of transitions, by using timed Petri nets - i.e. the time taken in fi ring of each transition - is proposed based on some simple principles that the number of tokens flowed into a place is equivalent to the number of tokens fl owed out. Finally, the availability of proposed method is confirmed by observing signalling transductions in biological pathways through simulation experiments of the apoptosis signalling pathways as an example.

Sialoadenitis progression in nonobese diabetic mice and its correlation with expression of apoptosis-associated proteins in salivary glands and serum IgG levels / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Sjögren syndrome (SS) is an autoimmune disorder characterized by chronic lymphocytic infiltration and decreased secretion in salivary glands. Apoptosis is one of the possible mechanisms involved in acinar epithelial destruction in SS. The role of apoptosis in the initiation and effect phase of sialoadenitis is still controversial. The aim of this study was to observe the roles of apoptosis-associated proteins and serum IgG levels in sialoadenitis progression in nonobese diabetic (NOD) mice.</p><p><b>METHODS</b>2-, 5-, 10-, 15-, 20-week female NOD and matched BALB/c control mice were selected. Saliva and tear flow rate were measured. Serum IgG level was tested by enzyme-linked immunosorbent assay (ELISA). Number of lymphocyte foci (NLF) in submandibular glands (SMGs) was counted under routine hematoxylin/eosin-stained sections. Expression of Fas, Bcl-2 and procaspase3 proteins as well as apoptotic cells in the SMGs were detected by immunohistochemical staining and by terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) assay respectively.</p><p><b>RESULTS</b>Decreased stimulated total flow rate (STFR) and lymphocyte foci in SMGs were first observed in the 10-week NOD group. STFR was negatively correlated with NLF (P < 0.05). Serum IgG in NOD mice was significantly higher than that of the control group (P < 0.05) and showed a positive correlation with NLF (P < 0.05). Fas expression in SMGs acinar cells in NOD mice increased with age and was significantly higher compared with that in the control group. Bcl-2 expression and procaspase3 expression in SMG acinar cells in each NOD group were lower compared with those of the age-matched control mice.</p><p><b>CONCLUSION</b>Abnormal expression of Fas and Bcl-2 in the SMGs and higher level of serum IgG may contribute to the initiation of sialoadenitis and cause the glandular destruction in NOD mice.</p>
