OBJECTIVETo investigate the different effects of an angiotensin II type 1 (AT(1)) receptor antagonist, losartan, and an angiotensin converting enzyme (ACE) inhibitor, fosinopril, on cardiomyocyte apoptosis, myocardial fibrosis, and angiotensin II (Ang II) in the left ventricle of spontaneously hypertensive rats (SHRs).
METHODSSHRs of 16-week-old were randomly divided into 3 groups: SHR-L (treated with losartan, 30 mg.kg(-1) x d(-1)), SHR-F (treated with fosinopril, 10 mg x kg(-1) x d(-1)), and SHR-C (treated with placebo). Each group consisted of 10 rats. Five rats, randomly selected from each group, were killed at the 8th and 16th week after treatment. Cardiomyocyte apoptosis, collagen volume fraction (CVF), perivascular collagen area (PVCA) and Ang II concentrations of plasma and myocardium were examined.
RESULTSCompared with the controls at the 8th and 16th week, systolic blood pressures were similarly decreased in both treatment groups. Left ventricular weight and left ventricular mass indexes were significantly lower in both treatment groups. However, the latter parameter at the 16th week was reduced to a less extent in the fosinopril group than that in the losartan group. Compared with the controls, cardiomycyte apoptotic index was significantly reduced at the 8th week only in the fosinopril group, and at the 16th week in both treatment groups. The index of the fosinopril group was lower than that of the losartan group at the latter endpoint examined. Compared with the controls, the left ventricular collagen volume fraction and perivascular collagen area at the 8th and 16th weeks were significantly reduced in the SHRs treated with either fosinopril or losartan. However, the collagen volume fraction at the latter endpoint in the fosinopril group was lower than that in the losartan group. Compared with the controls at endpoints, plasma and myocardium Ang II levels were significantly increased in the losartan group. However, plasma Ang II concentrations were not altered, and myocardium Ang II concentrations at the 8th and 16th weeks were significantly reduced in the fosinopril group.
CONCLUSIONSBoth losartan and fosinopril could effectively inhibit cardiomyocyte apoptosis and myocardial fibrosis and reverse heart hypertrophy. Fosinopril may be more effective in these cardioprotective effects, suggesting that the effects of both drugs are related to the inhibition of myocardium renin-angiotension-aldsterone system.

Objective:To study the stability and influencing factors of potassium iodate iodized salt that can be sold in Jilin Province.Methods:In November 2020, 10 large supermarkets were randomly selected in Jilin Province, and two kinds of potassium iodate iodized salts were randomly selected in each supermarket, with five copies of each kind, a total of 100 samples of iodized salt, and the iodine content was determined by spectrophotometry (iodide-starch blue light method). Iodized salt samples were classified according to different salt species (mine salt, sea salt and lake salt) and different production processes (refined salt and non-refined salt). The salt was stored at room temperature, and the iodine content in the salt was measured at 0, 10 and 20 days after opening the packaging. The iodine content attenuation rates of different salt species and different production processes were compared.Results:The mine salt, sea salt and lake salt in iodized salt samples were 45, 45 and 10 portions, respectively. The iodine contents of the 0th day of storage [(19.89 ± 1.38), (20.62 ± 1.91), (19.78 ± 1.01) mg/kg] were compared, and the difference was not statistically significant ( F = 2.57, P = 0.093). On the 10th day, the iodine content of mine salt was lower than that of sea salt and lake salt, and the differences were statistically significant ( P < 0.05); on the 20th day, the iodine content of mine salt was lower than that of sea salt, and the difference was statistically significant ( P < 0.05). There was a significant difference in the iodine content of mine salt stored at 0, 10 and 20 days ( F = 90.62, P < 0.001). The iodine content of sea salt and lake salt on the 20th day was significantly lower than that on the 0th and 10th day, and the differences were statistically significant ( P < 0.05). The iodine content attenuation rates of mine salt, sea salt and lake salt on the 0 - 10 days was compared with that on the 10 - 20 days, and the differences were statistically significant ( Z = 2.24, 2.94, 2.80, P < 0.05). There was a significant difference in the iodine content attenuation rates of mine salt, sea salt and lake salt during the 0 - 10 days of storage ( Z = 24.05, P < 0.001), there was no statistically significant difference in the iodine content attenuation rates on 10 - 20 days ( Z = 5.86, P = 0.053). There was no significant difference in iodine content attenuation rates between refined salt and non-refined salt on 0 - 10, 10 - 20 days ( Z = 1.16, 0.28, P > 0.05). There was no statistical significant difference in the iodine content attenuation rates of refined salt and non-refined salt on the 0 - 10 days compared with those of 10 - 20 days ( Z = 0.76, 1.90, P > 0.05). Conclusions:Iodine loss occurs at 20 days after opening the packaging of iodized salt in Jilin Province. The attenuation of iodine content is less affected by salt species and production processes. It is recommended to eat iodized salt within 20 days after opening the packaging.

Dental resin materials have been widely used in the treatment of dental defects. However, the polymerization shrinkage of the resin materials tends to cause microleakage and accumulation of bacterial plaque, which leads to secondary dental caries. Endowing dental resin with antibacterial properties is an important way to solve this problem. Adding antibacterial agents to dental resin is the main method to give it antibacterial properties. Antimicrobial agents are mainly divided into three types: release type, non-release type and mixed type. In terms of antibacterial effects, the selection and addition of antibacterial agents will affect the antibacterial and mechanical properties of dental resin materials; and the long-term antibacterial effect of antimicrobial agents in the oral cavity remains to be verified; as antimicrobial agents or other environmental factors can lead to drug resistance and even dormant persistent bacteria. In recent years, researchers have been committed to improving the antibacterial effect by modifying antibacterial agents. The sustained release of antimicrobial agents via carriers is also the main research direction. This paper reviews the research progress on the antibacterial properties of dental resin materials.

Objective To analyze the epidemiological characteristics and influencing factors of pulmonary infection in the elderly, and to construct a risk prediction model. Methods Stratified cluster sampling was used to randomly select 683 elderly patients in Zhangjiakou First Hospital as the investigation subjects. Sputum specimens were collected and sent for bacterial isolation, culture, identification, and drug sensitivity test. According to whether the patients had pulmonary infection, they were divided into pulmonary infection group (n=315) and non-pulmonary infection group (n=368). The clinical data of the two groups such as age, sex, COPD, and ICU admission were analyzed. Univariate analysis and logistic regression analysis were used to analyze the influencing factors of pulmonary infection in elderly patients, and a risk prediction model was established. Results A total of 331 strains of pathogenic bacteria were detected in 315 patients with pulmonary infection, and there were 207 strains (62.54%) of gram-negative bacteria detected, mainly including 95 strains (28.70%) of Acinetobacter baumannii and 71 strains (21.45%) of Klebsiella pneumoniae. There were 169 strains (26.28%) of gram-positive bacteria detected, mainly 68 strains (20.54%) of Staphylococcus aureus. In addition, there were 25 strains of fungi (7.55%). There were no significant differences in gender, smoking history, history of COPD, asthma, and stroke between the two groups (P>0.05). The proportion of patients aged≥70, mechanical ventilation, admission to ICU and recent respiratory tract infection in the experimental group was significantly higher than that in the control group (P<0.05). Multivariate logistic regression analysis showed that age, smoking history, mechanical ventilation, and ICU admission were independent risk factors for pulmonary infection in elderly patients (P<0.05). According to the above four independent influencing factors and corresponding regression coefficient of each factor, the prediction model of pulmonary infection in elderly patients was constructed, Z=-5.948+1.198× (age) +1.281×(smoking history) +2.029×(mechanical ventilation) +1.211×(ICU admission). Conclusion Lung infection in elderly patients in our hospital is dominated by gram-negative bacilli. Antibiotics should be rationally selected according to drug sensitivity results. Age≥70 years old and COPD can increase the risk of pulmonary infection in elderly patients, and the prediction model constructed can effectively predict the occurrence of pulmonary infection in elderly patients.

OBJECTIVE To evaluate the clinical efficacy and safety of XELOX chemotherapy (oxaliplatin+capecitabine) combined with antiangiogenic agent (apatinib) and immunotherapy (camrelizumab) in patients with inoperable metastatic colorectal cancer (CRC)of microsatellite stable (MSS) type. METHODS Clinical medical records of 40 patients with inoperable metastatic CRC of MSS type treated in Lishui People’s Hospital from January 2020 to January 2021 were retrospectively collected. According to the treatment plan, the patients were divided into control group (20 cases) and observation group (20 cases). Control group was given XELOX+apatinib regimen, while observation group was given XELOX+apatinib+camrelizumab regimen. Every 3 weeks was a treatment cycle, and the treatment lasted for 2 consecutive cycles. The objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS) and adverse events (AEs) were recorded for all patients. RESULTS The ORR and DCR of observation group were 65.0% and 85.0%, respectively; and the ORR and DCR of control group were 35.0% and 75.0%, respectively, with no statistical significance between 2 groups (P>0.05). The median PFS of observation group and control groups were 16.0 months and 8.0 months, respectively; and the median OS were 19.0 months and 12.5 months, respectively, with statistical significance between 2 groups (P<0.05). Each patient in both groups had at least one AEs, and the incidences of reactive skin capillary hyperplasia and hyperthyroidism in observation group (40.0%, 20.0%) were significantly higher than those in control group (both were 0) (P<0.05). The incidence of nausea and vomiting in control group (90%) was significantly higher than observation group (10%) (P<0.05). There were 14 cases (70.0%) of patients with grade 3 or above AEs in observation group, and only 5 cases (25.0%) in control group, with statistical significance between 2 groups (P<0.05). However, no severe AEs that could not be tolerated or fatal occurred in the two groups, which could be alleviated after drug withdrawal or treatment. CONCLUSIONS The efficacy of XELOX chemotherapy combined with apatinib and camrelizumab in inoperable metastatic CRC patients of MSS type is comparable to that of XELOX chemotherapy combined with apatinib, but it has certain advantages in ORR, PFS and OS, and controllable safety.

BackgroundThe depressive episode is one of the most prevalent mental illnesses worldwide. Relaxation therapy as a psychotherapy for depressive disorder has shown itself to be a viable tool, yet the existing research on relaxation therapy combined with sertraline in the treatment of depressive episodes in children and adolescents is severely limited. ObjectiveTo discuss the effect of relaxation therapy combined with sertraline on the new-onset depressive episodes in children and adolescents, and to provide references for the treatment of depressive episodes in children and adolescents. MethodsFrom January 1, 2019 to December 31, 2020, a sample of 422 children and adolescents with depressive episodes attending the Child Mental Health Department of Sichuan Mental Health Center and fulfilling the International Classification of Diseases, tenth edition (ICD-10) diagnostic criteria were enrolled, and they were classified into study group (n=208) and control group (n=214) using random number table method. All participants were offered sertraline, based on this, study group was assigned to relaxation therapy for 25~30 min per day, five days per week for a period of two weeks. Hamilton Depression Scale 24-item (HAMD-24) and Hamilton Anxiety Scale (HAMA) were applied at the enrollment, the end of 2 weeks of treatment and the end of the 2nd week after discharge. ResultsA total of 369 patients completed the study, including 185 in study group and 184 in control group. Analysis on HAMD-24 scores revealed a significant time effect, group effect and time×group interaction effect (F=813.279, 17.625, 8 994.905, P<0.01). Significant time effect, group effect, and time×group interaction effect were noted on HAMA scores (F=635.041, 10.716, 13 945.986, P<0.01). A reduction in HAMD-24 and HAMA scores was reported in study group at end of 2 weeks of treatment and end of the 2nd week after discharge compared with baseline (t=0.924, 0.359, P<0.01). At the end of the 2nd week after discharge, study group scored lower on HAMD-24 and HAMA compared to control group (t=0.210, 0.720, P<0.05). At the end of 2 weeks of treatment, study group resulted in greater improvements in depressive symptoms and anxiety symptoms than those of control group (95.14% vs. 66.30%, 89.18% vs. 71.74%, χ2=78.942, 22.526, P<0.05). The overall efficacy rate yielded no statistical difference between two groups at end of the 2nd week after discharge (P>0.05), and no statistical difference was found in the adverse reactions between the two groups (P>0.05). ConclusionCompared with sertraline alone, its combination with relaxation therapy may achieve a better short-term efficacy in the treatment of depressive episode in children and adolescents.
