Objective:To investigate the current status of coping behaviors among caregivers of children with disabilities in the context of rehabilitation and its influencing factors. Methods:From December, 2019 to January, 2020, and August to September, 2020, a total of 358 caregivers (parents) of children with disabilities were surveyed in Shanghai. They were evaluated in the context of rehabilitation of children with disabilities with Coping Health Inventory for Parents (CHIP). Multiple linear stepwise regression analysis was used to explore the influencing factors. Results:The total score of CHIP was (106.00±23.45) and the average score of CHIP was (2.36±0.52). Among the caregiver factor, mothers (B = 7.607, 95%CI 2.477 to 12.737, P = 0.004), and caregivers who didn't need to care for others (B = 5.758, 95%CI 1.174 to 10.343, P = 0.014) reported higher CHIP score. Among the child factors, higher CHIP score was reported in caregivers who had more partners (B = 2.925, 95%CI 1.233 to 4.618, P < 0.001), participated in public space activities more frequently (B = 3.906, 95%CI 1.743 to 6.068, P < 0.001) and perceived changes in rehabilitation outcomes (B = -16.832, 95%CI -31.471 to -2.193, P = 0.024); CHIP score was lower in thoses of 3 to < 6 years old (B = -7.914, 95%CI -15.157 to -0.671, P = 0.032) and with intellectual disability children (B = -11.153, 95%CI -21.360 to -0.947, P = 0.032). Among the environmental factors, caregivers who perceived more friendly social attitude (B = 2.560, 95%CI 0.615 to 4.505, P = 0.010) reported higher CHIP score. Conclusion:It is proposed to learn the coping needs of caregivers of children with disabilities in the context of rehabilitation. The coping behaviors of caregivers are influenced by multiple factors, such as children's individual, caregivers and environment.

Purpose::Traumatic brain injury (TBI) is one of the leading causes of disability and death in modern times, whose evaluation and prognosis prediction have been one of the most critical issues in TBI management. However, the existed models for the abovementioned purposes were defective to varying degrees. This study aims to establish an ideal brain injury state clinical prediction model (BISCPM).Methods::This study was a retrospective design. The six-month outcomes of patients were selected as the end point event. BISCPM was established by using the split-sample technology, and externally validated via different tests of comparison between the observed and predicted six-month mortality in validating group. TBI patients admitted from July 2006 to June 2012 were recruited and randomly divided into establishing model group and validating model group. Twenty-one scoring indicators were included in BISCPM and divided into three parts, A, B, and C. Part A included movement, pupillary reflex and diameter, CT parameters, and secondary brain insult factors, etc. Part B was age and part C was medical history of the patients. The total score of part A, B and C was final score of BISCPM.Results::Altogether 1156 TBI patients were included with 578 cases in each group. The score of BISCPM from validating group ranged from 2.75 to 31.94, averaging 13.64 ± 5.59. There was not statistical difference between observed and predicted mortality for validating group. The discrimination validation showed that the BISCPM is superior to international mission for prognosis and analysis of clinical trials (IMPACT) lab model.Conclusion::BISCPM is an effective model for state evaluation and prognosis prediction of TBI patients. The use of BISCPM could be of great significance for decision-making in management of TBI.

Objective:To analyze the status quo and development of the Hope Houses for individuals with spinal cord injury (SCI) in Shanghai. Methods:In June, 2018, the organizers and managers of Hope Houses from 16 districts in Shanghai were investigated with the self-designed questionnaires, which covered the personal characteristics, knowledge of related policy, development of projects and obstacles, and rehabilitation recognition. The descriptive analysis and correlational analyses were conducted. Results:Totally, eleven organizers and 16 managers were investigated. The knowledge of related policy for organizers was not good enough. Eight Hope Houses in 16 districts in Shanghai were operated by social organizations. The average implementation rate of projects in Hope Houses was 60.6%, and the highest was rehabilitation knowledge education (96.3%). There was insufficient provision in legal services, job skills training, rehabilitation nursing guidance, job referral, medical referral and education referral, etc. The main related factors limiting the development of the Hope Houses were lacks of budgets, social consensus and professionals. The rehabilitation cognition of organizers and managers was generally good, but the cognition of rehabilitation principles and rehabilitation value needed to be strengthened. Conclusion:The Hope Houses for individuals with SCI in Shanghai work well, and the rehabilitation cognition of organizers and managers is satisfactory. It should be strenghened in resource input, comprehensive rehabilitation and standard of management, to expand the service timely.

OBJECTIVETo evaluate the effect of FLAMIGEL (hydrogel dressing) on the repair of residual burn wound.

METHODSSixty burn patients with residual wounds hospitalized in 6 burn units from November 2011 to May 2012 were enrolled in the multi-center, randomized, and self-control clinical trial. Two residual wounds of each patient were divided into groups T (treated with FLAMIGEL) and C (treated with iodophor gauze) according to the random number table. On post treatment day (PTD) 7 and 14, wound healing rate was calculated, with the number of completely healed wound counted. The degree of pain patient felt during dressing change was evaluated using the visual analogue scale (VAS). The mean numbers of wounds with score equal to zero, more than zero and less than or equal to 3, more than 3 and less than or equal to 6, more than 6 and less than or equal to 10 were recorded respectively. Wound secretion or exudate samples were collected for bacterial culture, and the side effect was observed. Data were processed with repeated measure analysis of variance, t test, chi-square test, and nonparametric rank sum test.

RESULTSWound healing rate of groups T, C on PTD 7 was respectively (67 ± 24)%, (45 ± 25)%, and it was respectively (92 ± 16)%, (72 ± 23)% on PTD 14. There was statistically significant difference in wound healing rate on PTD 7, 14 between group T and group C (F = 32.388, P < 0.01). Ten wounds in group T and four wounds in group C were healed completely on PTD 7, with no significant difference between them (χ(2) = 0, P > 0.05). Forty-two wounds in group T and seven wounds in group C healed completely on PTD 14, with statistically significant difference between them (χ(2) = 42.254, P < 0.01). Patients in group T felt mild pain during dressing change for 37 wounds, with VAS score higher than zero and lower than or equal to 3. Evident pain was observed in patients of group C during dressing change for 43 wounds, and it scored higher than 3 and less than or equal to 6 by VAS evaluation. There was statistically significant difference in mean number of wounds with different grade of VAS score between group T and group C (Z = -4.638, P < 0.01). Staphylococcus aureus, Pseudomonas aeruginosa, Klebsiella pneumoniae, E. coli, Baumanii, and Staphylococcus epidermidis were all detected in both groups, but there was no statistical difference between group T and group C (χ(2) = 0.051, P > 0.05). No side effect was observed in either of the two groups during the whole trial.

CONCLUSIONSFLAMIGEL can accelerate the healing of residual burn wounds and obviously relieve painful sensation during dressing change.

The purpose of this study is to investigate the penetration effects and mechanism of N-arginine chitosan (ACS). This novel transdermal enhancer with a mimetic structure of cell-penetration peptides was synthesized by introducing hydrophilic arginine groups to the amino-group on chitosan's side chain. The structure of ACS was confirmed by FT-IR, 1H NMR and element analysis. In addition, attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR) was used to study the protein conformation and the water content of stratum corneum, and the result suggested that ACS can change the orderly arrangement of the molecules in the stratum corneum, making the stack structure of keratin become loose. And ACS can increase the water content of the stratum corneurn. Inverted fluorescence microscope and flow cytometry were used to examine penetration effect of ACS on Hacat cell. The result confirmed that the uptake of ACS was enhanced with increased substitution degree of arginine by 4-8 folds compared to chitosan. In vitro penetration studies on three electrical types of drugs were carried out using three model drugs of negatively charged aspirin, positively charged terazosin and neutral drug isosorbide mononitrate by the method of Franz diffusion cells. The results showed that ACS has obviously penetration of the negatively charged drug aspirin, and certain penetration of neutral drug issorbide mononitrate, but inhibition of positively charged terazosin. In vivo imaging technology research results show that the ACS can significantly enhance the fluorescence intensity of morin, which is the auto-fluorescence anionic drug. These obtained results suggested that ACS, as a promising transdermal enhancer, can change the structure of the keratinocytes and analog penetrating peptides promote absorption, but have certain selectivity for the drug.

Because of the changed metabolic behaviors of cancer cells, tumor cells uptake a corresponding larger amount of glucose in physiological condition when compared with normal cells. And they were prone to metabolize glucose for generating energy in anaerobic glycolysis ways in order to grow quickly. Anaerobic glycolysis consumes more glucose than aerobic way when the same amount of energy is obtained, which also results in large demand of glucose in tumor cells. This review briefly describes therapy methods related to characteristic mentioned above, and summarizes the research progress of drugs, diagnostic reagents and carriers conjugated with glucose, glucose derivatives or other kinds of sugars for cancer targeting. Furthermore, typically relative research reports from 2012 till now were listed and analyzed.

BACKGROUNDMultidrug resistance (MDR) is a main reason for paclitaxel (TAX) treatment failure. Indirubin-3'-monoxime (IRO) and Matrine are traditional Chinese medicines, which may reverse the resistance of tumor cells to some chemotherapy drugs, but the relationship between paclitaxel resistance and Matrine is still unclear. The aim of this study was to explore the potential molecular mechanism of IRO and Matrine in reversal of TAX resistance.

METHODSIn this study, MTT assay was used to measure the non-cytotoxic dosage of IRO and Matrine on NCI-H520/TAX25 cells and determine the reversal extent of TAX resistance under non-toxic doses. In addition, RT-PCR and Western blotting were used to evaluate the mRNA expression and the protein level of survivin, Oct-4, and Sox-2 in NCI-H520/TAX25 cells using semi-quantitative methods.

RESULTSThere was no obvious inhibition on sensitive cell strains and drug-resistant strains, when the final concentration was at lest 4 µmol/L for IRO and 100 µmol/L for Matrine. So 4 µmol/L of IRO and 100 µmol/L of Matrine were considered as the reversal dosage. When 4 µmol/L of IRO or 100 µmol/L of Matrine were used together with TAX, the sensitivity to TAX increased evidently in NCI-H520/TAX2 cells; the reversal rate of IRO and Matrine was about 1.92 (43.56/22.6 nmol/L) and 1.74 (43.56/25.0 nmol/L), respectively. The mRNA expression and the protein level of survivin, Oct-4, and Sox-2 in NCI-H520/TAX25 decreased significantly (P < 0.05) after addition of IRO or Matrine in TAX treatment, compared to that of TAX treatment alone.

CONCLUSIONThe decrease in both mRNA expression and protein level of survivin, Oct-4, and Sox-2 might be the molecular mechanism, by which IRO and Matrine mediate the reversal of TAX resistance.
