Objective To probe into the status and correlation between elder abuse tendency and psychological resilience of family caregivers of the elderly with chronic diseases. Methods Totally 402 family caregivers of the elderly with chronic diseases were investigated by the Chinese version of Caregiver Abuse Screening and Conner-Davidson Resilience Scale. Then the results underwent statistical analysis. Results Nearly 63.68%(256/402) family caregivers had the risk of elder abuse tendency. The median of family caregivers′resilience score was 53, lower than normal population(Z=-10.106, P=0.000), and was significantly negatively correlated with elder abuse tendency(r=-0.480, P=0.000).And caregivers′ high level of resilience was a protective factors for elder abuse tendency. Conclusions Nurses should motivate the family caregivers of the elderly with chronic diseases to adapt successfully when faced stress which could be associated with resilience. Thus the psychological resilience would play a role of protective effect against elder abuse tendency, with the purpose of reducing the risk for abusing the elderly who suffered from chronic diseases.

Objective To probe into the status quo of maltreatment tendency among family caregivers of elderly patients with chronic diseases and its influence factors.Methods Totally 402 family caregivers of the elderly patients with chronic diseases were selected and surveyed by using the Chinese version of caregiver elder abuse assessment scale and the results underwent statistical analysis.Results 63.70％ of family caregivers in elderly patients with chronic diseases had the elder abuse risk tendency and its influence factors were involved with both aspects of family caregivers and the care recipients,including the gender,cultural level and self-care ability of daily living in the elderly patients with chronic diseases and the age,cultural level,care period and living together with elderly in caregivers.Conclusion The elder abuse problem in the patients with chronic diseases should be paid more attention to,which needs the collaboration of multidisciplinary team,various effective ways should be adopted to relieve the family caregivers' pressure for reducing the occurrenc of elder abuse risk.

Objective To compare the effects of two patient-controlled epidural analgesia(PCEA) after cesarean section and the incidence of nausea vomiting, lethargy and urinary retention. Methods Sixty cesarean section patients were randomly divided into two groups, each group had 30 patients. Group Ⅰ: 0.15% bupivacaine hydrochloride plus tramadoL group Ⅱ: 0.179% ropivacaine mesylate plus nefopam hydrochloride. Postoperative 0-48 hours within the period pain (visual analog score, VAS)and the corresponding time motor block level(the Bromage scale), and incidence of nausea vomiting, lethargy and urinary retention were recorded. Results VAS difference was not statistically significant (P>0.05), Bromage scores in group Ⅱ was shorter than those in group Ⅰ(P<0.05), the incidence rates of nausea vomiting, lethargy and urinary retention in group Ⅱ were lower than those in group Ⅰ(P<0.01). Conclusion Ropivacaine mesylate combined with nefopam hydrochloride PCEA analgesic effect is certain, which shows a clear superiority in the motor function recovery and reducing the incidence of adverse reactions.

Objective To study the apoptosis mediated by cisplatin on human colorectal tumors (HCT116) cell line and its mechanisms in vitro. Methods The apoptosis levels of HCT116 cells mediated by cisplatin at vari-ous time and in different concentration were measured by M30-ApoptosisTM -ELISA-kits and flow cytometry assay. The expressions of the protein p53,p21 and Bcl-2 were assessed through Western-Blotting. Results Cisplatin in-hibited the proliferation in a time-and dose -dependant manner ( F = 1129. 383, P = 0. 000 and F = 125. 267, P = 0. 000, respectively). The sub-G1 peak detected by flow cytometry at 24,48,72 hours of the apoptosis rates showed a significant difference between the experimental group and the control group (χ2= 5. 669,14.110,12. 221, P = 0. 010,0.003,0. 000,respectively). We found significant differences on the HCT116 cell growth between different time under cisplatin effect (χ2 = 14.008 ,P =0. 003 ). There were significant difference on the CK18-Asp237-Asp396 re-leased by HCT116 cell between different casplatin concentration (F =48. 667 ,P =0.000) as well as different times ( F = 1194. 394, P = 0.000). The Western-Blotting results indicated that the expression level of the p53 ( t = 9.873, -2.906,7. 229,2.776,P =0.000,0. 007,0. 000,0. 011 ) and p21 (t = - 10. 692, - 8. 867, - 15. 063, - 16.281, P = 0. 000,0.001,0.000,0.000 ,respectively) increased gradually, while there are no effect on the expression of the protein Bcl-2(t=1.429,2.011,2.247,2.001,P=0. 178,0.069,0.053,0.062,respectively). Conclusions Cis-platin can induce the apoptosis on HCT116 cells and thus inhibit the reproduction of tumor cells by recovering the function of p.53.

PPARγ2 gene C1431T polymorphism was assayed by PCR-RFLP in 200 polycystic ovary syndrome( PCOS)patients and 150 normal subjects. Serum adiponectin and leptin levels were determined by ELISA method. Polymorphism of the site might be associated with serum leptin and adiponectin concentrations and thiazolidinedione treatment in women with PCOS ( P<0.05 or P<0.01).

Forty women with polycystic ovary syndrome( PCOS) were enrolled. Basal plasma and urine cortisol, pituitary hormones, homeostasis model assessment for insulin resistance, and plasma cortisol in 0. 25 mg dexamethasone inhibition test were determined. In over-weight or obese PCOS patients, cortisol levels before and after inhibition test were increased (P<0. 05 or P<0. 01 ). The results suggest that the feed-back regulation of glucocorticoids to hypothalamas-pituitary is impaired and the change in hypothalamic-pituitary-adrenal axis is associated with insulin resistance.

To test the hypothesis that the first degree relatives of Chinese women with polycystic ovarian syndrome (PCOS) have higher risk of cardiovascular disease than those without PCOS.The metabolic phenotype and risks of cardiovascular disease were evaluated in 110 family members of 35 women with PCOS and 85 unrelated healthy control subjects without family history of diabetes and PCOS ( four age- and weight-matched subgroups ).The prevalence of impaired glucose tolerance was 51.4％ in mothers and 57.5％ in fathers with their daughters suffering from PCOS.The first degree relatives of PCOS women had significantly higher serum fasting insulin level,homeostasis model assessment for insulin resistance,insulin area under the curve,and lower insulin sensitivity index in all subgroups than the control subjects( P＜0.05 ).The control subjects had significantly elevated high molecular weight-adiponectin levels and decreased high sensitive-C reactive protein levels compared to the first degree relatives of PCOS women in all subgroups.Parents and brothers,but not sisters,of women with PCOS had significantly higher total cholesterol and low density lipoprotein-cholesterol ( P＜ 0.05 ),as well as triglyceride levels ( P＜ 0.05 ),compared with control subjects.The first degree relatives of PCOS women had features of insulin resistance and increased risk of cardiovascular disease.

To study the antiviral effect of Hypericum perforatum L. extract (HPE) on influenza A virus (IAV) (H1N1) in vitro and in vivo. Cytopathic effect (CPE) and neutral red (NR) dye uptake were used to examine the antiviral effect of HPE on Madin Darby Canine Kidney (MDCK) cells which were infected with IAV in vitro. HPE was effective against influenza A virus (IAV) in vitro, with a 50% effective concentration (EC50) of 40 μg/mL. The mean 50% cytotoxic concentration (CC50) in the MDCK used in these experiments was 1.5 mg/mL. Ribavirin was run in parallel with EC50 values of 5.0 μg/mL; the mean CC50 for ribavirin was 520 μg/mL. Oral gavage administrations of HPE or ribavirin to mice infected with the IAV were highly effective in preventing death, slowing the decline of arterial oxygen saturation, inhibiting lung consolidation and reducing lung virus titers. The minimum effective dose of HPE in these studies was 31.25 mg/kg/day, which was administered twice daily for 5 d beginning 4 h prior to virus exposure. Below a dosage of 2000 mg/kg/day, almost all treated mice survived, which suggests that HPE is of low toxicity. Ribavirin's minimum effective dose was 40 mg/kg/day with the LD50 determined to be 200 mg/kg/day. Delay of the initiation of either HPE or ribavirin therapy, using approximately 1/3 LD50 dose each time, could still be protective as late as 48 h after exposure to the IAV. While both agents appeared to have similar efficacy against IAV infections, HPE was considered to be less toxic and may warrant further evaluation as a possible therapy for influenza.

Objective: To investigate the characteristics and trends of malaria cases in Lishui City, Zhejiang Province from 2012 to 2023, so as to provide a basis for improving malaria prevention and control measures. Methods: Case data of malaria in Lishui City from 2012 to 2023 were collected from the Parasitic Disease Control Information Management System of the National Information System for Disease Control and Prevention in China. The parasite species, source of infection, temporal distribution, population distribution, geographical distribution, and clinical diagnosis and treatment of the cases were descriptively analyzed. Results: A total of 169 malaria cases were reported in Lishui City from 2012 to 2023, and P. falciparum malaria was the main type, accounting for 79.88% (135 cases). The positive rate of Plasmodium detection was 3.30‰(169/51 212), the highest was 5.41‰ (18/3 327) in 2017, and the lowest was 0.38‰ (1/2 632) in 2021. Malaria cases were reported in every month from 2012 to 2023, with 91 cases (53.85%) reported from May to October. There were 168 imported cases, of which 163 (96.45%) originated from Africa. There were 127 male cases (75.15%), and the majority of cases were aged 20 to 49 years, with 138 cases accounting for 81.65%. The majority of the occupation was overseas labor export workers, with 164 cases accounting for 97.04%. A total of 161 cases (95.27%) were registered residents of Lishui City, and cases were reported from all nine counties (cities, districts), with Qingtian County and Liandu District having the higher numbers of 98 and 41 cases, respectively. The median interval from onset to hospital visit for malaria cases was 2.00 (interquartile range, 4.00) days, and the median interval from hospital visit to diagnosis was 0 (interquartile range, 1.00) day. The diagnostic rate of first-diagnosed malaria cases in municipal and county medical institutions was 95.90% (117/122) and 91.49% (43/47), respectively, with no statistical significance (P>0.05). Conclusions The P. falciparum malaria was the predominant type in Lishui City from 2012 to 2023, with the majority of cases being imported. Male overseas labor export personnel aged 20 to <50 were the key demographic.

Objective:To standardize the naming of organ at risk (OAR) and target area during cervical cancer radiotherapy based on AAPM TG-263.Methods:After self-programming of Matlab software to implement the reading and resolution of radiotherapy structure files, the naming of each substructure was automatically output, recorded and restored. After naming all substructures, the structure names were classified by keywords. According to TG-263, a standard naming conversion table of OAR and target area was developed, and the classified structure names were standardized through procedures. Finally, the standardized named radiotherapy structure files were output and imported into the treatment planning system (TPS).Results:The radiation structure of 144 patients with cervical cancer was successfully transformed and displayed correctly in TPS. Before the transformation, the naming of OAR and target area lacked of uniform norms and standards, and the naming of the same structure significantly differed. After the transformation, 43 naming methods of OAR and 74 naming methods of the target area were unified into 20 and 8 naming methods, which were more convenient for staff understanding and communication.Conclusion:The standardization of cervical cancer radiotherapy structure naming can reduce the inconsistency of naming and provide reference for the standardized naming of pelvic tumors.
