Objective: To investigate the subjective well-being and its influencing factors among grassroots civil servants in Jiaxing City, Zhejiang Province, so as to provide the basis for enhancing their subjective well-being. Methods: Grassroots civil servants were selected from five counties (cities, districts) in Jiaxing City using a convenient sampling method from November to December 2021. Demographic information were collected through questionnaire surveys. Psychological capital, social support, and subjective well-being were assessed using the Positive Psychological Capital Questionnaire, Social Support Rating Scale and General Well-being Scale, respectively. Factors affecting subjective well-being were analyzed by using a multiple linear regression model. Results: A total of 5 689 participants were surveyed, including 3 696 males (64.97%) and 1 993 females (35.03%). There were 968 participants aged 18 to <31 years (17.02%), 2 202 participants aged 31 to <41 years (38.71%), 1 483 participants aged 41 to <51 years (26.07%) and 1 036 participants aged 51 to 60 years (18.21%). Among them, 4 485 participants had a bachelor's degree (78.84%), and 4 870 participants were married (85.60%). The median score of subjective well-being among grassroots civil servants was 87.00 (interquartile range, 30.00) points. Multiple linear regression analysis showed that age (31 to <41 years, β'=-0.087; 41 to <51 years, β'=-0.098; 51 to 60 years, β'=-0.044), educational level (college degree, β'=-0.093; bachelor's degree, β'=-0.130; master's degree or above, β'=-0.085), psychological capital (β'=0.710) and social support (β'=0.161) were factors affecting subjective well-being among grassroots civil servants. Conclusion Grassroots civil servants who aged 18 to <31 years, have high school education or below and score high in psychological capital and social support may have higher levels of subjective well-being.

Objective To evaluate the effects of celecoxib on tumor growth and cell apoptosis in human triple-negative breast cancer (TNBC) xenografts in nude mice.Methods Human TNBC MDA-MB-231 cells were inoculated subcutaneously into BALB/c nude mice.The mice (n=32) were then randomly divided into 4 groups,the control group and the celecoxib group (receiving 25,50,100 mg·kg-1·d-1 respectively).At the end of the study,tumor tissues were collected and tumor volume was measured.Cell apoptosis was determined by flow cytometry (FCM) analysis.NF-κB p65 and pS0 protein levels were measured by immunohistochemistry.Caspase-3 and survivin protein levels were detected by western blotting.Results celecoxib at dose of 25,50 and 100 mg·kg-1·d-1 inhibited the tumor growth significantly,compared with the control group.FCM results showed that apoptotic rates were (13.58±3.16) ％ and (21.91±4.75) ％ in moderate and high dose of celecoxib-treated group,compared with (3.15±1.73) ％ in control group (t =6.736,P ＜ 0.05;t =12.151,P ＜ 0.05).p65 expressions were 79.3 ％,46.7 ％ and 23.9 ％ in low,moderate and high dose of celecoxib-treated group,compared with 89.7 ％ in control group (x2 =3.312,P ＜ 0.05; x2 =10.785,P ＜ 0.05;x2 =15.900,P ＜ 0.05).Besides,western blotting analysis demonstrated that celecoxib significantly downregulated survivin expression,while upregulated the active form of caspase-3 expression.Conclusion Celecoxib could suppress TNBC tumor growth and induce cell apoptosis,which might be partially associated with inactivation of p65 and downregulation of survivin.

Objective To explore the effects of impaired glucose metabolism and impaired blood lipoprotein metabolism on heart rate variability(HRV) in aged male hypertension patients and to have an insight into the correlation between the years of impaired glucose metabolism and the patients’ HRV. Methods 120 male subjects were divided into three groups: simple hypertension patients (group A, 40 people), hypertension patients with diabetes mellitus (group B, 40 people), and hypertension patients with diabetes mellitus and impaired blood lipoprotein metabolism (group C, 40 people). All subjects had 24h recordings of ECG. The data of HRV time domain were collected and analyzed to gain an insight into the effects of the impaired glucose metabolism and impaired blood lipoprotein metabolism on patients’ HRV. In group C, patients were divided into normal TC subgroup and high TC subgroup according to the index of TC (TC

Objective To observe the impacts of Kechuanning on expression of signal transducer and activator of transcription 6 (STAT 6) in CD4+, CD8+T lymphocytes of athma rats induced by virus, and analyze the mechanism of Kechuanning in treating asthma induced by RSV. Methods The PBMC was isolated from the peripheral blood, CD4+T, CD8+T lymphocyte was separated by immunomagnetic beads. The purity and activity of CD4+T and CD8+T lymphocytes were measured by using flow cytometry, trypan-blue dye exclusion test. The protein expression of STAT6 was detected by fluorescence-activated cell sorting. Results The descending progress of the trial were supported by the purity and activity of CD4+T, CD8+T lymphocyte. CD4+T lymphocyte in the asthma model group were increased (P<0.01), however the increase of CD8+T lymphocyte were not significant (P>0.05). The expression of the protein of STAT6 in the treated group with Kechuanning decoction were decreased than that in the model group (P<0.01). Compared with Dexamethasone and Salbutamol group, there were no significant differences (P>0.05). Conclusion Kechuanning decoction could decrease the protein of STAT6 in CD4+, CD8+T lymphocyte, thereby it could regulate the disorder of Th1/Th2, thus prevent and treat the asthmatic attack induced by virus.

Objective To explore the expression and clinical significance of EphA2 and E-eadherin in colorectal carcinoma.Methods The expression of EphA2 and E-eadherin in 67 cases of eoloreetal carcinoma and 28 cases of normal large intestine tissues were determined by immunohistochemieal method(S-P method),and their relationship to elinicopathological characteristics were analyzed.Results The positive expression of EphA2 and negative expression of E-cadherin in colorectul carcinoma tissues were significantly higher than those in normal intestine tissues(P<0.01).F111e positive expression of EphA2 and negative expression of E-eadherin were positively correlated with tumor histological grade,invasive depth and lymph node metastasis(P<0.01 orP<0.05),but not correlated with tumor～ross type(P> O.05).The expression of EphA2 was negatively related with E-cadherin.Conclusions The abnormal expression of EphA2 and E-cadherin may be together involved in the development and progression of eolorectal carcinoma,It may be a good marker for monitoring the malignant degree and the prognosis of colorectal carcinoma by combining E-eadherin and EphA2.

The tuberous roots of Aconitum carmichaeli are largely used in traditional Chinese medicine and widely grown in Jiangyou, Sichuan, China. During the growth process, this medicinal plant releases a large amount of allelochemicals into soil, which retard the growth and development of near and late crops. Therefore, a pure culture experiment was thus carried out by seed soaking to study the allelopathic effects of extracts from tuberous roots of A. carmichaeli (ETR) on the seed germination and young seedling growth of Lolium perenne, Trifolium repens, and Medicago sativa, the late pasture grasses after cultivation of A. carmichaeli. The results showed that three pasture grasses varied significantly in seed germination and young seedling growth in response to ETR concentrations. Seed germination of M. sativa was stimulated by low ERT concentration (0.01 x g(-1)), while all of pasture grass seeds germinated poorly in solution with 1.00 g x L(-1). Seed soaking with 1.00 g x L(-1) also inhibited significantly the growth of pasture young seedlings, with M. sativa showing the highest seedling height reduction of 42.05% in seeding height, followed by T. repens (40.21%) and L. perenne with about 11%. Cultivation of L. perenne could thus be beneficial to increase whole land productivity in A. carmichaeli-pasture grass cropping systems. In addition, hydrolysis of protein, starch, and inositol phosphates was blocked and free amino acids, soluble sugars and phosphorus were decreased in seeds by seed soaking with ETR, which could be one of the reason for the inhibition of seed germination. There was a significant reduction in root vigor, nitrate reductase, and chlorophyll after the seed treatment with ETR, indicating the suppression of nutrient uptake, nitrate assimilation, and photosynthesis by allelopathic chemicals in ETR, which could lead to the slow growth rate of pasture grass seedlings.
