Objective To investigate effect of the transtheoretical model and stages of change (TTM) on self-management paradigm,serum calcium and phosphorus levels in patients undergoing maintenance hemodialysis (MHD).Methods Total 140 MHD patients were separated into two groups as the intervention group (65 of 70 cases completed with TTM) and the control group (63 of 70 cases completed with routine nursing care) by random number table.Data obtained by using hyperphosphatemia related knowledge questionnaires and Self-management Rating Scale before and after intervention.The levels of serum calcium and phosphorus between the above groups were compared.Results The scores of self-management behavior were higher in control group after 3 months intervention,the differences was statistically significant (P ＜ 0.05),in which the scores of problem solving (2.97 ± 0.28),self care activities (2.99±0.28),relationships (3.13±0.35) and emotional treatment (2.80 ± 0.32) in experimental group was apparently higher than control group at the same time,the scores were (2.63±0.32),(2.67±0.38),(2.76±0.42),(2.44±0.36) respectively in conrtol group,t values were-0.907,-7.68,-6.03 and-8.43,respectively.And also,there was statistically significant difference between the two groups in serum phosphorus level [(1.81±0.49) mmol/L vs.(2.56±0.69) mmol/L],the product of calcium and phosphorus [(55.33±14.45) mg2/dl2 vs.(72.35±20.94) mg2/dl2],serum parathyroid hormone [238.00 (130.35,413.85) ng/L vs.297.75 (155.02,760.37) ng/L] (t=11.01,8.43,Z=-2.09,P＜0.05).Conclusions TTM is conducive to promote behavior change,improve self-management conduct,and also reduce serum phosphorus level in MHD patients.

BACKGROUND: Unilateral spinal epidural anesthesia with ropivacaine can reduce the perioperative pain in the elderly undergoing hip or knee arthroplasty, but choosing which concentration of small dose hypobaric ropivacaine is an issue of concern.OBJECTIVE: To explore the anesthetic and analgesic effects of unilateral spinal epidural anesthesia with different concentrations of low dose hypobaric ropivacaine in senile knee or hip replacement.METHODS: Ninety patients undergoing knee or hip replacement in the Henan Province Hospital of TCM from August 2014 to December 2015 were enrolled, and randomized into 0.15%, 0.5% and 0.25% ropivacaine groups (n=30 per group), followed by spinal epidural anesthesia at L3-4 or L2-3 lumbar interspace, respectively.RESULTS AND CONCLUSION: (1) The order of the flat subsided time and motor block recovery time was as follows:0.15% ropivacaine group < 0.25% ropivacaine group < 0.5% ropivacaine group; the onset time of motor block was longest in the 0.25% ropivacaine group, followed by 0.5% ropivacaine group, and shortest in the 0.15% ropivacaine group (all P < 0.05). (2) The order of the visual analogue scale scores at 1, 5, and 10 hours after anesthesia and 24 hours postoperatively was as follows: 0.5% ropivacaine group < 0.25% ropivacaine group < 0.15% ropivacaine group (P < 0.05). (3) The change levels of heart rate and blood pressure were highest in the 0.5% ropivacaine group, followed by 0.15% ropivacaine group, and lowest in the 0.25% ropivacaine group. (4) The incidence of adverse events was highest in the 0.5% ropivacaine group, followed by 0.15% ropivacaine group, and lowest in the 0.25% ropivacaine group (P < 0.05). (5) To conclude, 3 mL of 0.25% ropivacaine exhibits desired anesthetic effect.

Objective To delineate the expressions of ubiquitin-specific proteinase 49 (USP49)and FK506 binding protein 51 (FKBP51) in the spinal dorsal horns and their roles in rats with diabetic neuropathic pain (DNP).Methods Male SD rats were fed with high glucose and high fat diet with an intraperitoneal injection of 1％ streptozocin to establish DNP rat models.DNP rats were allocated into DNP group,control shRNA group (KC group) and knockdown USP49 group (KD group,n=10);saline,Ad-scrambled shRNA (3×108 PFU/mL) and Ad-USP49-shRNA (3×108 PFU/mL) were intrathecally injected into the rats of the three groups.Another 10 normal rats were chosen as control group (C group).Thermal withdrawal latency (TWL) and mechanical withdrawal threshold (MWT) were measured one d before model establishment,one and 7 d after model establishment,one,three and 7 d after intrathecal injection.The mRNA and protein expressions of USP49,FKBP51 and glucocorticoid receptor α (GRα)in dorsal horn neurons were detected by real time-PCR and Western blotting.Results (1) TWL showed no significant difference among the four groups one d before model establishment (P＞0.05);three and 7 d after intrathecal injection,TWL in KD group was significantly prolonged as compared with that in the DNP group,and significantly shortened as compared with that in C group (P＜0.05).(2) MWT showed no significant difference among the four groups one d before model establishment (P＞0.05);three and 7 d after intrathecal injection,MWT in KD group was significantly higher as compared with that in the DNP group,and significantly lower as compared with that in C group (P＜0.05).(3) As compared with DNP group,KD group had significantly decreased mRNA expressions of USP49 and FKBP51,and statistically increased mRNA GRα expression (P＜0.05).(4) As compared with DNP group,KD group had significantly decreased protein expressions of USP49 and FKBP51,and statistically increased protein GRα expression (P＜0.05).Conclusion Specific knockdown of USP49 expression is associated with improvement of heat hyperalgesia and mechanical hyperalgesia in DNP rats,which may be attributed to the de-ubiquitination ofFKBP51 by USP49.

Aim To explore the effect of survivin in PC12 cells against injuries induced by cobalt chloride(CoCl_2).Methods PC12 cells were exposed to CoCl_2 at different doses in different time to set up the chemical hypoxia induced PC12 cells injuries model.Cell viability was tested by using cell counter kit-8.Dose-effect(200～1 000 μmol·L~(-1))and time-effect(0～48 h)relationship between hypoxia induced by CoCl_2 and the expression of survivin was evaluated by western blot.Results PC12 cells viability was inhibited significantly by CoCl_2 in a dose and time dependent manners;At the concentrations from 200 to 600 μmol·L~(-1) CoCl_2 for 24 h,survivin expression was upregulated in a dose dependent manner,peaking at 600 μmol·L~(-1) CoCl_2 treatment,exceeding this concentration of CoCl_2,with dose increasing,survivin expression decreased.At the dose of CoCl_2 up to 1 000 μmol·L~(-1),survivin did not express basically;Treatment with 600 μmol·L~(-1) CoCl_2 in different time,within the range of 0～36 h,the expression of survivin enhanced in time dependent manner.But with the extension of time,survivin expression was declining; 17-allylamino-17-demethoxygeldanamycin (2 μmol·L~(-1)),an inhibitor of Hsp90,not only decreased survivin overexpression but also obviously enhanced the injuries of PC12 cells induced by CoCl_2,which didn't damage PC12 cells alone.Conclusion Upregulation of survivin expression may be one of the endogenous defense mechanisms for PC12 cells against chemical hypoxia.

Objective To observe the changes of endothelin-1 (ET-1) and prostaglandin E2 (PGE2) in exhaled breath condensate (EBC) and serum of patients with acute respiratory distress syndrome (ARDS) after treated by Qingfeitang and investigate its clinical value.

(2) After treatment, the levels of PGE2 in serum of the Qingfeitang treatment group were significantly lower than that of the control group. (3) The oxygenation index difference before and after treatment of Qingfeitang in the treatment group was higher than in the control group. (4) The duration of mechanical ventilation of the Qingfeitang treatment group was significantly less than that of the control group. Conclusions Qingfeitang could be an effective method for alleviating acute respiratory distress syndrome.

Objective:To study the clinical value of the ISBAR communication model based on nursing priorities in nursing ward rounds.Methods:Using a quasi-experiment method, 104 patients who received secondary and tertiary care from April to June 2020 were set as the control group, and 122 patients who received secondary and tertiary care from July to September 2020 were set up as the experimental group, with non-randomized method. The experimental group used the ISBAR communication model based on nursing priorities for nursing ward rounds, and the control group used the traditional method for nursing ward rounds. The abilities of bedside nurses collecting the patients′condition, the bedside nurses′ condition observation and the nurses′ critical thinking were compared between the two groups, and the patients' nursing quality and satisfaction were also compared.Results:The scores of the bedside nurses′ knowledge of the patients′ condition were 81.14±3.09 in the test group and 75.90±2.84 in the control group, with statistically significant difference ( t value was -12.88, P<0.01). The scores of the bedside nurses′ ability in observing patients′ condition were 140.50 (137.00, 144.50) in the experimental group and 135.50 (128.75, 139.00) in the control group, with statistically significant difference ( Z value was -3.399, P<0.01). The scores of the Critical Thinking Disposition Inventory Chinese-version (CTDI-CV) were 309.82±36.33 in the experimental group and 286.86±33.54 in the control group, with statistically significant difference ( t value was -2.177, P<0.05). The scores of patient care quality evaluation were 62.50 (60.00, 64.00) in the experimental group and 59.00 (55.00, 61.50) in the control group, with statistically significant difference ( Z value was -6.47, P<0.01). The patient discharge satisfaction score of the experimental group was 53.00 (48.75, 55.00), and that of the control group was 51.00 (44.00, 54.00), with statistically significant difference ( Z value was -3.56, P<0.01). Conclusions:The application of ISBAR communication model based on nursing priorities in nursing ward rounds had a significant promotion effect on the improvement of nurses' abilities of collecting the patients′ condition, observing patients′ condition, and critical thinking, and can effectively improve nursing care quality and patients′ satisfaction.
