Methods A sample survey was made on family health services dehvered to Dongying residents and an analysis was made using an economic model of demand elasticity. Results The coefficients of price elasticity for basic chronic disease care in the urban and rural areas of Dongying were respectively -0.268 and -0.469 and the coefficients of income elasticity were respectively 0.176 and 0.370. The price and income factors had a fairly big influence on the demand of the rural residents. Conclusion The price factor of health services must he taken into serious consideration in managing medical and health services institutions so as to genuinely improve the demand for health services by residents.

Objective:To investigate the effect of retinoid-interferon-induced mortality (GRIM-19) gene on the apoptosis of colon cancer. Methods: A GRIM-19 eukaryotic expression vector (pCMV-Flag-GRIM-19) was constructed and transfected into SW480 cells. Expressions of GRIM-19 and apoptosis-related proteins were detected by Western blotting analysis. Apoptosis of SW480 cells was measured by Annexin-V/PI assay and mitochondrial membrane potential JC-1 staining. Results: The GRIM-19 eukaryotic expression vector pCMV-Flag-GRIM-19 was successfully constructed. Expression of GRIM-19 in SW480 cells was up-regulated and that of apoptosis-related protein Bcl-xl was down-regulated after transfection with pCMV-Flag-GRIM-19. Apoptosis rate was (7.7±1.39)% in SW480 cells transfected with pCMV-Flag empty vector and (15.0 ± 2.52)% in pCMV-Flag-GRIM-19 transfected cells (P<0.05). Mitochondrial membrane potential was decreased in (7.5±2.09)% of pCMV-Flag transfected cells and (17.5±3.07)% of pCMV-Flag-GRIM-19 transfected cells (P<0.05). Conclusion: In vitro GRIM-19 transfection can effectively induce apoptosis of colon cancer SW480 cells.

This study examined the synergetic effect of class IA Phosphoinositide 3-kinases catalytic subunit p110β knockdown in conjunction with oxaliplatin treatment on colon cancer cells. Down-regulation of p110β by siRNA interference and oxaliplatin treatment were applied in colon cancer cell lines HT29, SW620 and HCT116. MTT assay was used to measure the inhibitory effect of p110β knockdown on the proliferation of colon cancer cell lines. SubG1 assay and Annexin-V FITC/PI double-labeling cytometry were applied to detect cell apoptosis. And cell cycle was evaluated by using PI staining and flow cytometry. The expression of caspase 3, cleaved PARP, p-Akt, T-Akt and p110β was determined by western blotting. The results suggested that down-regulation of p110β expression by siRNA obviously reduced cell number via accumulation in G(0)-G(1) phase of the cell cycle in the absence of notablely increased apoptosis in colon cancer cell lines HT29 and SW620 (S phase arrest in HCT116). Moreover, inhibition of p110β expression increased oxaliplatin-induced cell apoptosis and cell cycle arrest in HT29, HCT116 and SW620 cell lines. In addition, increases of cleaved caspase-3 and cleaved PARP induced by oxaliplatin treatment were determined by immunoblotting in p110β knockdown group compared with normal control group and wild-type group. It is concluded that down-regulated expression of p110β could inhibit colon cancer cells proliferation and result in increased chemosensitivity of colorectal cancer cells to oxaliplatin through augmentation of oxaliplatin-induced cell apoptosis and cell cycle arrest.

Objective:To study the risk factors for ipsilateral severe hearing impairment in patients with hemifacial spasm (HFS) after microvascular decompression (MVD).Methods:MVD was performed in 3700 patients with HFS, admitted to our hospital from October 2007 to August 2020; according to the existence of ipsilateral severe hearing impairment, these patients were divided into severe hearing impairment group and non-severe hearing impairment group. The clinical data of these patients were compared. Multivariate linear regression analysis was used to determine the independent influencing factors for ipsilateral severe hearing impairment.Results:Forty-five patients (1.2%) had ipsilateral severe hearing impairment after MVD; no one got recovery of hearing impairment during the follow-up period (0.6-11.8 years, 6.3 years in average). As compared with those in the non-severe hearing impairment group, patients in the severe hearing impairment group had significantly older age, significantly higher percentages of male patients, and patients with left HFS, hypertension, and diabetes mellitus, statistically higher percentage of patients having small posterior fossa volume, arachnoid thickening and adhesion, and vertebral artery compression, significantly lower percentage of patients with anterior inferior cerebellar artery compression, significantly higher percentage of patients with arteriosclerosis of offending arteries and difficult decompression ( P<0.05). Multivariate linear regression analysis revealed that hypertension, vertebral artery compression, arteriosclerosis of offending artery and difficult decompression were independent risk factors for severe hearing impairment in patients with HFS after MVD. Conclusion:It's difficult to get recovery for severe hearing impairment in patients with HFS after MVD; this complication is much common in patients with hypertension, vertebral artery compression, arteriosclerosis of offending artery or difficult decompression.

In order to examine the effect of GRIM 19 on colon cancer cell SW480, the recombinant adenovirus carrying GRIM19 gene was constructed and transfected into SW480 cells. GRIMI9 cDNA was amplified by PCR with the template pcxn2-GRlMl9 and cloned into the shuttle plasmid pAdTrack-CMV. The plasmid pAdTrack-CMV-GRIM19 was linearized by PmeI and homologously recombined with bone plasmid pAdEasy-1 in BJ5183, followed by identification by enzyme diges- tion. After transfection of linearized pAd-GRIM19 with PacI into HEK293 cells, Ad-GRIMI9 was obtained and amplified by 3 circles. SW480 cells were infected with Ad-GRIM19. The apoptosis rate was detected by flow cytometry. Agarose electrophoresis revealed the bands of recombinant plasmids identified by enzyme digestion were in the right range corresponding with expectation. Under the fluorescent microscopy, the package of Ad-GRIM19 in HEK293 cells and the expression of Ad-GRIM19 in SW480 cells were observed. The transfection of Ad-GRIM19 into SW480 cells in-creased the apoptosis rate of SW480 cells as compared with controls. It was concluded that Ad-GRIM19 was successfully constructed and the overexpression of GRIM19 in colon cancer cell lines could promote the apoptotic cell death.

Phosphatidylinositol 3-kinase (PI3K) signaling plays an important role in the regulation of cellular lipid metabolism and non-alcoholic fatty liver disease (NAFLD). However, little is known about the role of the regulatory subunits of PI3K in lipid metabolism and NAFLD. In this study, we characterized the functional role of PIK3R3 in fasting-induced hepatic lipid metabolism. In this study, we showed that the overexpression of PIK3R3 promoted hepatic fatty acid oxidation via PIK3R3-induced expression of PPARα, thus improving the fatty liver phenotype in high-fat diet (HFD)-induced mice. By contrast, hepatic PIK3R3 knockout in normal mice led to increased hepatic TG levels. Our study also showed that PIK3R3-induced expression of PPARα was dependent on HNF4α. The novel PIK3R3-HNF4α-PPARα signaling axis plays a significant role in hepatic lipid metabolism. As the activation of PIK3R3 decreased hepatosteatosis, PIK3R3 can be considered a promising novel target for developing NAFLD and metabolic syndrome therapies.

Objective: To elucidate the association between biorhythm disorders and health risk behaviors in adolescence, so as to provide reference for appropriate interventions. Methods: From March to April 2023, 2 381 adolescents in Shanghai were selected as research objects using convenience sampling and stratified random cluster sampling methods. The Self rating Questionnaire of Biological Rhythm Disorders for Adolescents (SQBRDA) and the self report health risk behaviors questionnaire were used to investigate the status of adolescent biorhythm disorders and nine kinds of health risk behaviors, while a multivariate Logistic regression model was employed to analyze the association between the two variables. Results: The average SQBRDA score was (68.25±0.42) The incidence and detection rates of health risk behaviors in the groups with no co occurrence, mild co occurrence, moderate co occurrence, and severe co occurrence were 234(9.83%), 1 176(49.39%), 830(34.86%) and 141(5.92%), respectively. The total SQBRDA score was positively correlated with the risk of co occurrence of health risk behaviors. The risk of mild co occurrence, moderate co occurrence, and severe co occurrence of health risk behaviors was 9.05 times (95% CI =4.25-19.15, P <0.01), 44.55 times (95% CI =20.75-96.05, P <0.01) and 110.05 times (95% CI =40.65-297.95, P <0.01) higher, respectively, among adolescents with higher scores of biorhythm disorders compared to adolescents with lower scores of biorhythm disorders. Conclusions Health risk behaviors among adolescents in Shanghai draw attention to a serious phenomenon whereby biorhythm disorders are positively correlated with the risk of co occurrence. Comprehensive interventions aimed at addressing adolescent health risk behaviors should focus on regulating biorhythm disorders.

Objective:To investigate the factors related to child care environment and the association between child care environment and children′s early development.Methods:Using stratified cluster random sampling, a total of 22 509 children newly enrolled to kindergarten from 187 kindergartens of 16 districts in Shanghai in 2017 were enrolled. A survey was conducted by parent-reported questionnaire. The index of child care environment (ICCE) and the early human capacity index were used to evaluate family child care environment and children′s early development respectively. The sample was divided into four groups based on the ICCE score: the lowest family childcare environment (ICCE≤10 scores), lower middle (ICCE=11 scores), upper middle (ICCE=12 scores), and the highest (ICCE=13 scores). The linear regression model and Logistic regression model were used to analyze the factors related to child care environment and the association between child care environment and children′s early development respectively.Results:A total of 22 067 children aged (44±7) months, including 11 425 boys (51.8%) and 10 642 girls (48.2%), participated in this study. The multnomial linear regression revealed girls, higher maternal education, higher household annual income, single-child, non-divorced parents, and early breastfeeding experience were protective factors of child care environment for children newly enrolled to kindergarten ( β=0.064, 0.238, 0.119, 0.096, 0.113, and 0.032; 95% confidence interval ( CI): 0.020-0.108, 0.175-0.302, 0.058-0.180, 0.046-0.146, -0.012-0.242, and -0.051-0.116; all P<0.01). The multinomial Logistic regression revealed compared with the highest child care environment group, the odds ratio of children′s early development risks in upper midclle, lower middle, and the lowest child care environment groups were 1.543 (95% CI: 1.373-1.735, P<0.01), 2.537 (95% CI: 2.254-2.856, P<0.01), and 4.198 (95% CI: 3.757-4.690, P<0.01), respectively. Conclusions:The child care environment is not only significantly related to family structure and socioeconomic status, but also to early breastfeeding experience. The child care environment plays an important role in promoting childhood early development.
