ABSTRACT
Objective To observe the expression of tyrosine kinase 2(JAK2)and signal transducer and activator of transcription 3(STAT3)in myocardial tissue of rats with myocardial ischemia-reperfusion injury(MIRI)by electroacupuncture at"Neiguan"point,and explore the mechanism of electroacupuncture in up regulating JAK2/STAT3 signal pathway,promoting the expression of anti-inflammatory factors,and reducing MIRI injury.Methods Thirty male SD rats with normal echocardiography were randomly divided into sham operation group,model group and electroacupuncture group,with 10 rats in each group.MIRI models were prepared by ligation of left anterior descending coronary artery(LAD)in model group and electroacupuncture group,while in sham operation group,only threading was performed without ligation.In the electroacupuncture group,electroacupuncture(density wave,2 Hz/100 Hz,2 mA)at bilateral"Neiguan"points was performed on the 1st,3rd and 5th days after the modeling operation,once a day,20 minutes each time.The left ventricular ejection fraction(LVEF)of rats on the 1st,3rd and 5th day after operation was observed by echocardiography to evaluate cardiac function;HE staining was used to observe the pathological changes of rat myocardium;The myocardial fibrosis was observed by Masson staining;The expression of IL-4 and IL-6 in myocardium was detected by ELISA;The expressions of IL-1β and IL-10 in myocardial tissue were detected by immunohistochemistry;The expression of JAK2,p-JAK2,STAT3,p-STAT3 protein in myocardial infarction area was measured by Western blot.Results Compared with sham operation group,EF in model group decreased significantly(P<0.05),fibrosis area increased(P<0.05),IL-4,IL-6,IL-10,IL-1β The content of JAK2,p-JAK2,STAT3,p-STAT3 protein increased(P<0.05);Compared with the model group,the EF of rats in the electroacupuncture group increased(P<0.05),the fibrotic area of rats in the electroacupuncture group decreased(P<0.05),the content of IL-4 and IL-10 increased,and IL-6 and IL-1β The expression of JAK2,p-JAK2,STAT3,p-STAT3 protein increased(P<0.05).Conclusion Electroacupuncture at Neiguan point can significantly up regulate JAK2/STAT3 signal pathway,reduce the secretion of proinflammatory factors,increase the expression of anti-inflammatory factors,and alleviate myocardial ischemia reperfusion injury in rats.
ABSTRACT
Objective: To observe the effects of electroacupuncture (EA) at Neiguan (PC6) on arrhythmia during acute myocardial ischemia-reperfusion and the expression of connexin 43 (Cx43) in rats. Methods: A total of 40 Sprague-Dawley male rats were used. Ten rats were randomly selected as the blank group, and the remaining 30 rats were randomly divided into a model group and an EA group, with 15 rats in each group. Before modeling, rats in the EA group received one session of EA intervention at bilateral Neiguan (PC6) for 30 min; the other groups were treated with the same grasping and anesthesia for 30 min without intervention. PowerLab physiological recorder was used to record electrocardiograph within 30 min of infarction. After the experiment, cardiac tissue and serum were collected from rats. Hematoxylin-eosin (HE) staining was used to observe the morphological changes of myocardial tissue in the ventricular infarction area of rats in each group. The expression of Cx43 protein in the myocardium of each group was detected by Western blotting (WB). Enzyme-linked immunosorbent assay (ELISA) was used to determine the activity of Na+-K+-ATPase in myocardial tissue and the serum content of endogenous digitalis-like factor (EDLF) in rats. Results: There was no statistical difference in arrhythmia score between the EA group and the model group, but the total duration and average duration of arrhythmia in the EA group were decreased (P<0.01). HE staining showed that compared with the blank group, myocardial cells in the model group were disorganized and seriously damaged. The pathological changes in the EA group were similar to those in the model group, but the damage was relatively minor. The results of WB showed that compared with the blank group, the Cx43 expression in myocardial tissue of the model group was decreased (P<0.01); compared with the model group, the Cx43 expression in the EA group was increased (P<0.01); compared with the blank group, the Na+-K+-ATPase activity in myocardial tissue of the model group was significantly decreased (P<0.01); compared with the model group, the Na+-K+-ATPase activity in the EA group was increased (P<0.01). ELISA results showed that compared with the blank group, the serum EDLF content in the model group was significantly increased (P<0.01); compared with the model group, the EDLF content in the EA group was decreased (P<0.01). Conclusion: EA at Neiguan (PC6) can delay and reduce the onset of arrhythmia during myocardial infarction in the rat model of myocardial ischemia-reperfusion. Its mechanism of action may be related to the regulation of the Cx43 expression in myocardial tissue, improvement of the activity of Na+-K+-ATPase in myocardial tissue, and increase in the content of serum EDLF.
ABSTRACT
Nucleic acid drugs are highly applicable for cancer immunotherapy with promising therapeutic effects, while targeting delivery of these drugs to disease lesions remains challenging. Cationic polymeric nanoparticles have paved the way for efficient delivery of nucleic acid drugs, and achieved stimuli-responsive disassembly in tumor microenvironment (TME). However, TME is highly heterogeneous between individuals, and most nanocarriers lack active-control over the release of loaded nucleic acid drugs, which will definitely reduce the therapeutic efficacy. Herein, we have developed a light-controllable charge-reversal nanoparticle (LCCN) with controlled release of polyinosinic-polycytidylic acid [Poly(I:C)] to treat triple negative breast cancer (TNBC) by enhanced photodynamic immunotherapy. The nanoparticles keep suitably positive charge for stable loading of Poly(I:C), while rapidly reverse to negative charge after near-infrared light irradiation to release Poly(I:C). LCCN-Poly(I:C) nanoparticles trigger effective phototoxicity and immunogenic cell death on 4T1 tumor cells, elevate antitumor immune responses and inhibit the growth of primary and abscopal 4T1 tumors in mice. The approach provides a promising strategy for controlled release of various nucleic acid-based immune modulators, which may enhance the efficacy of photodynamic immunotherapy against TNBC.
ABSTRACT
Objective:To analyze the level and latent categories of the training needs of the nursing staff of the social volunteer teams in Jiangsu Province, and to provide basis for the targeted training.Methods:From March to July in 2018, 224 elderly care teachers from 13 social volunteer teams of 100 Red Cross societies in Jiangsu Province were surveyed for the knowledge of the care for the aged and the needs of training by the self-designed questionnaires. A total of 207 valid questionnaires were collected, with an effective recovery rate of 92.4%. SPSS 21.0 and Latent GOLD 5.1 software were used for description analysis, hierarchical clustering and latent category analysis.Results:The number of answer of "very need" to knowledge and skills among the aged care teachers for the elderly, such as psychological care, elderly volunteer services and recreational activities for the elderly, was 196, 196 and 193, with a proportion of 94.7%, 94.7% and 93.2%, respectively. Cluster analysis showed that training needs could be divided into four aspects: life care knowledge and skills, health care knowledge and skills, psychological care knowledge and skills, and spiritual comfort knowledge and skills. The results of latent category analysis showed that the aged care teachers could be divided into three groups based on their different training needs: high demand group for overall knowledge and skills, partial demand group for overall knowledge and skills, and high demand group for medical care and psychological care knowledge and skills. The corresponding latent probability of the three groups were 80.2%, 13.0%, 6.8%, respectively.Conclusion:The training for the aged care of social volunteer teams should pay attention to the teaching of spiritual comfort knowledge and skills for the elderly. The training program should be oriented to the multi-level and individualized needs of the teachers, so as to meet the needs of the aged care teachers for their own development.

ABSTRACT
Chemotherapy is among the limited choices approved for the treatment of hepatocellular carcinoma (HCC) at intermediate and advanced stages. Preferential and prolonged drug exposure in diseased sites is required to maximize the therapeutic index of the drug. Here, we report an injectable supramolecular peptide hydrogel as an intraperitoneal depot for localized and sustained release of triptolide for the treatment of orthotopic HCC. We chose peptide amphiphile C-GNNQQNYKD-OH-based nanofibers as gelators and carriers for triptolide. Sustained triptolide release from the hydrogel was achieved over 14 days , with higher accumulation in and cytotoxicity against human HCC Bel-7402 in comparison with L-02 fetal hepatocytes. After intraperitoneal injection, the hydrogel showed prolonged retention over 13 days and preferential accumulation in the liver, realizing HCC growth inhibition by 99.7 ± 0.1% and animal median survival extension from 19 to 43 days, without causing noticeable pathological changes in the major organs. These results demonstrate that injectable peptide hydrogel can be a potential carrier for localized chemotherapy of HCC.
ABSTRACT
Hyperglycemia is a common complication of critical patients. Currently, clinical assessment of the changes in the blood glucose of critical patients is mainly based on the intermittent monitoring of peripheral blood glucose at a certain time point. This method cannot get the true blood glucose fluctuation, and it is more difficult to find asymptomatic hyperglycemia and hypoglycemia, so the guiding value of blood glucose control is limited. Arterial blood is the most accurate sample of blood glucose monitoring, so it is urgent to ensure the accuracy of arterial blood sample. A continuous arterial blood glucose monitoring equipment was independently developed by general surgical intensive care unit (ICU) of the First Affiliated Hospital of Nanjing Medical University, and National Utility Model Patent of China was obtained. It could greatly improve the efficiency of medical staff, and provide accurate and dynamic statistic data that would be an important basis for doctors' clinical decision-making. The continuous arterial blood glucose monitoring equipment was mainly composed of arterial pressure measuring monitor, program-controlled dynamic blood glucose meter, wire, electric switch, integrated collecting syringe, electric clip, rotary electric bracket, and blood glucose test strips, etc., which could be continuously and dynamically monitor patient blood glucose levels and perform various additional value-added functions such as automatic recording and alarming.
ABSTRACT
Objective To explore impacts of social support and coping styles on self-perceived burden of patients with spinal cord injury. Methods A total of 150 patients with spinal cord injury were investigated using Self-Perceived Burden Scale, Social Support Rating Scale, and Medical Coping Modes Questionnaire by cross-sectional survey method. Results The total score of self-perceived burden was at a moderate level and the average score was (33.98±10.76) points. Resignation of coping style had directly positive effect on self-perceived burden, path coefficient was 0.19, subjective support, support utilization had directly negative effect on SPB, path coefficient were-0.18,-0.21;objective support exerted directly negative influence on self-perceived burden through resignation of coping style. In other words, the resignation of coping style played a mediating role between social support and self-perceived burden, effect size was 0.034. Conclusions Most of patients with spinal cord injury suffer from moderate self-perceived burden. Objective support, subjective support, support utilization and the resignation of coping style are the important factors that affect self-perceived burden.
ABSTRACT
Objective To explore the rehabilitation outcome and influencing factors of functional recovery in patients with nontraumatic spinal cord injury (NTSCI). Methods A retrospective analysis was done on 49 cases suffering from NTSCI who recepted rehabilitation therapy from December 2014 to November 2016. The main indicator of the rehabilitation effect was Modified Barthel Index (MBI). A total of 49 cases were divided into two groups, effective group (31 cases) and ineffective group (18 cases) according to whether their MBI on discharge had beated the target setted on admission. The following factors:ages, gender, injury causes, injury level, injury grade, injury severity, the types of paralysis, hospitalization time, sick time, complications number, MBI on admission and discharge, operation, early rehabilitation were evaluated by Univarite analysis and Logistic stepwise regression to assess how they influenced rehabilitation outcome. Results After systematically rehabilitation training, MBI had apparent improvement, from (38.98 ± 24.90) score on admission to (56.35 ± 22.69) score on discharge and had statistical significance(Z=-4.95, P=0.00), which showed that rehabilitation training can effectively improve patients′ self-care ability of daily living. Regression analysis found that the MBI on admission (OR=1.044, P=0.010) and hospitalization time(OR=1.044, P=0.039) had a noticeable effect on the rehabilitation outcome, while all the other factors, such as age, sex, injury grade, injury level, injury severity, complications number hadn′t show concrete effect on rehabilitation outcome. Conclusions Patients with NTSCI should have early rehabilitation, medical staff should assess their admission MBI, make a strict rehabilitation training plan to improve rehabilitation efficiency, shorten hospitalization time, improve the patients quality of life.
ABSTRACT
OBJECTIVE:To compare the effects of morphine and nalbuphine on related indexes of maternal after cesarean sec-tion. METHODS:A total of 120 maternal underwent cesarean section were randomly divided into observation group(60 cases)and control group (60 cases). After surgery,observation group was given Nalbuphine hydrochloride injection 20 mg+0.75% Ropiva-caine hydrochloride injection 20 mL for patient-controlled epidural analgesia. Control group was given Morphine hydrochloride injec-tion 8 mg+0.75% Ropivacaine hydrochloride injection 20 mL for patient-controlled epidural analgesia. VAS score,systolic pres-sure,diastolic pressure,respiration rate(RR),SpO2 at the onset of analgesia(T0),6 h(T1),12 h(T2),24 h(T3)and 48 h(T4) after analgesia as well as the levels of IL-6,IL-8,CRP and PRL at T0,T3,T4 were observed in 2 groups. The satisfaction rate of analgesia and the occurrence of ADR were also observed. RESULTS:There was no statistical significance in satisfaction rate of an-algesia between 2 groups(96.67% vs. 98.33%,P>0.05). At T0,T1,T4,there was no statistical significance in VAS score between 2 groups(P>0.05). VAS scores of 2 groups at T2-3 were significantly higher than at T0,T1,T4,with statistical significance(P0.05). There was no statistical significance in diastolic pres-sure,RR and SpO2 between 2 groups at T0-2(P>0.05). The systolic pressure of 2 groups at T3-4 were significantly higher than at T0, with statistical significance(P0.05). There was no statisti-cal significance in the levels of IL-6,IL-8,CRP or PRL between 2 groups at T0(P>0.05). The levels of IL-6,IL-8 and CRP in 2 groups at T3 were significantly higher than at T0,but the observation group was significantly lower than the control group;at T4,the levels of IL-6,IL-8 and CRP in control group were significantly higher than at T0,with statistical significance(P0.05). The levels of PRL in 2 groups at T3-4 were significantly higher than at T0,and increased gradually as time;the observation group and significantly higher than the control group,with statistical significance (P<0.05). The incidence of ADR in observation group was significantly lower than control group,with statistical significance(P<0.05). CONCLUSIONS:For maternal after cesarean section,nalbuphine is similar to mor-phine in analgesic effect and cardiovascular effect,but it is better than morphine in reducing inflammatory level,promoting lacta-tion and safety.
