BACKGROUND: Sliding cupping has been used for treating cervical spondylosis, with the effects of dredging the meridian system, activating qi and removing blood stasis.OBJECTIVE: To probe into symptomatic improvement of cervical spondylosis with sliding cupping and the relationship between curative effect and course of disease as well as age.DESIGN: Self controlled observation.SETTING: Department of Physiotherapy, General Hospital of Air Force of Chinese PLA.PARTICIPANTS: Totally 100 out-patients with cervical spondylosis receiving treatment in the Department of Physiotherapy, General Hospital of Air Force of Chinese PLA were involved from December 2000 to December 2003. Among them, 39 cases were male and 61 cases were female; 9 cases were under 30 years old, 38 cases were 31 to 40 years old, 42 cases were 41 to 50 years old and 11 cases were above 50 years old. There were 36 cases with less-than-one-year course of disease, 49 with 1 to 5-year course and 15 with more-than-5-year course. Fifty-one cases were cervical type; 25 cases vertebral artery type; 24 cases nerve root type. X-ray examination revealed that there were 69 cases whose cervical vertebral physiological curvature became straight or reverse, or with certain degree of degenerative change. Vertebroarterial blood supply insufficiency was detected in 23 cases by rheoencephalogram.INTERVENTIONS: The patients were asked to be in prone sitting position,their nape and shoulder were fully exposed, and the negative pressure cupping was applied to patient' s nape and shoulder until petechiae appeared on the skin. The treatment was given once or twice a week. After one-month treatment, the curative effect was calculated according to subjective symptoms, signs, and the results of X-ray and rheoencephalogram examination before and after treatment. Symptom disappearance: pain was 0 grade; the cervical vertebral physiological curvature restored by 10°- 15° and rheoencephalogram showed that the contraction peak velocity of the vertebroarterial blood supply became normal. Marked improvement: the pain reduced by more than 2 grade, the cervical vertebral physiological curvature restored by 6°9° and rheoencephalogram showed that the vertebroarterial blood supply restored to 80% of the normal range. Improvement: the pain reduced by 1 grade, the cervical vertebral physiological curvature restored by 3°- 5° and rheoencephalogram showed that the vertebroarterial blood supply restored to 40% - 80% of the normal range. Inefficacy: the pain did not reduce, the cervical vertebral physiological curvature restored by less than 3° and rheoencephalogram showed that the vertebroarterial blood supply became less than 40%.RESULTS: According to the intention-to-treat analysis, 100 patients entered the result analysis. For symptom disappearance, marked improvement,improvement, inefficacy there were 27, 17, 5 and 2 cases respectively in cervical type; 8, 10,4 and 3 cases respectively in the vertebral artery type;4,9,7 and 4 cases respectively in the nerve root type. There were 19, 12, 3 and 2 cases respectively with less-than-one-year course of disease; 18, 19, 7 and 5 cases respectively with 1 to 5-year course; 2, 5, 6 and 2 cases respectively with more-than-5-year course. And there were 5, 3 and 1 cases respectively with age < 30 years; 18, 13, 4 and 3 cases respectively with age of 31 to 40 years; 15, 18, 5 and 4 cases respectively with age of 41 to 50years; 1, 2, 6 and 2 cases respectively with age > 50 years.CONCLUSION: The effect of sliding cupping was good for patients with cervical spondylosis of vertical type, next of vertebroarterial type and bad of nerve root type. The shorter the course of disease is, the younger the patient is, and the better the curative effect is.

Objective: To explore the role of angiotensin receptor type I (AT1)-calcineurin (CaN) signaling pathway in transient outward potassium ion channel (Ito) remolding in hypertrophic atrial myocytes of neonatal rats. Methods: 1 day old neonatal rats’ atrial myocytes were isolated and the cells were divided into 4 groups:①Control group, normal cells were cultured for 24 h,②Stretching group, the cells were cultured for 24 h with mechanical stretching to induce hypertrophy,③Telmisartan group, the cells were treated by telmisartan at 1 μmol/L for 1 h, then cultured for 24 h and ④Cyclosporin-A (CsA) group, the cells were treated by CsA at 0.25 μg/ml for 1 h, then cultured for 24 h. The ratios of protein/DNA in myocytes were compared between Control group and Stretching group, cell hypertrophy was deifned by mRNA expression of atrial natriuretic peptide (ANP). Ito changes were detected by whole-cell patch clamping technique, proteins expressions of Kv4.3 and CaN A subunit were examined by Western blot analysis. Results: Compared with Control group, Stretching group showed obviously decreased Ito density and Kv4.3 protein expression, while increased CaN A protein expression; Compared with Stretching group, the above effects were reduced in Telmisartan group and CsA group. Conclusion: AT1-CaN signaling pathway was involved in the regulation of Ito channel remodeling in hypertrophic atrial myocytes of neonatal rats.

Objective To evaluate the effect of propofol postconditioning on necroptosis during hy-poxia-reoxygenation (H∕R) injury in diabetic cardiomyocytes. Methods Normally cultured H9C2 cardio-myocytes were divided into 5 groups (n= 19 each) using a random number table: control group (group C), high glucose group (group HG), H∕R group, propofol postconditioning (group P) and solvent dimethyl sulfoxide (DMSO) control group (group DMSO). H9C2 cells were incubated for 48 h in DMEM culture medium containing 5. 5 and 25 mmol∕L glucose in group C and group HG, respectively. In group H∕R, H9C2 cells were incubated for 48 h in DMEM culture medium containing 25 mmol∕L glucose and then un-derwent H∕R. H9C2 cells were incubated for 48 h in DMEM culture medium containing 25 mmol∕L glucose and then underwent H∕R, and propofol at the final concentration of 50 μmol∕L was added at the onset of reoxygenation in group P. In group DMSO, H9C2 cells were incubated for 48 h in DMEM culture medium containing 25 mmol∕L glucose and then underwent H∕R, and DMSO at the final concentration of 150μmol∕L was added at the onset of reoxygenation. The model of cardiomyocyte H∕R injury was established by subjecting cardiomyocytes to 6 h of hypoxia followed by 12 h of reoxygenation. At 12 h of reoxygenation, the cell viability was measured by CCK8 assay, the product of lactate dehydrogenase (LDH) in culture medium was measured, the level of reactive oxygen species (ROS) was determined by flow cytometry, cardiomyo-cyte apoptosis was detected by TUNEL, and the expression of receptor-interacting protein 1 ( RIP1), RIP3, Bax, Bcl-2, activated caspase-3 and caspase-3 was determined by Western blot. The apoptotic rate and ratio of activated caspase-3∕caspase-3 were calculated. Results Compared with group C, the cell via-bility was significantly decreased, the product of LDH was increased, the level of ROS and apoptotic rate were increased, the expression of RIP1, RIP3 and Bax was up-regulated, the expression of Bcl-2 was down-regulated, and the ratio of activated caspase-3∕caspase-3 was increased in group HG ( P < 0. 05). Compared with group HG, the cell viability was significantly decreased, the product of LDH was increased, the level of ROS and apoptotic rate were increased, the expression of RIP1, RIP3 and Bax was up-regula-ted, the expression of Bcl-2 was down-regulated, and the ratio of activated caspase-3∕caspase-3 was in-creased in group H∕R (P<0. 05). Compared with group H∕R, the cell viability was significantly increased, the product of LDH was decreased, the level of ROS and apoptotic rate were decreased, the expression of RIP1, RIP3 and Bax was down-regulated, the expression of Bcl-2 was up-regulated, and the ratio of acti-vated caspase-3∕caspase-3 was decreased in group P (P<0. 05), and no significant change was found in the indexes mentioned above in group DMSO (P>0. 05). Conclusion The mechanism by which propofol post-conditioning ameliorates H∕R injury in diabetic cardiomyocytes may be related to inhibiting necroptosis.

Hip fractures are among the most common fractures in the elderly, presenting to be a leading cause of disability and mortality. Surgical treatment is currently the main treatment method for hip fractures. The incidence of perioperative malnutrition is increased after hip fractures in the elderly due to the comorbidities, decreased basal metabolic rate, accelerated protein breakdown, weakened anabolism and surgical stress. However, malnutrition not only increases the incidence of postoperative complications, but also leads to increased mortality, indicating an important role of perioperative nursing management of nutrition for the elderly patients with hip fractures. At present, there still lacks scientific guidance and application standards on perioperative nursing management of nutrition for the elderly patients with hip fractures. Therefore, the Orthopedic Nursing Committee of Chinese Nursing Association and the Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Expert consensus on perioperative nursing management of nutrition for elderly patients with hip fractures ( version 2023) according to evidence-based medical evidences and their clinical experiences. Fourteen recommendations were made from aspects of nutrition screening, nutrition assessment, nutrition diagnosis, nutrition intervention and nutrition monitoring to provide guidance for perioperative nursing management of nutrition in elderly patients with hip fractures.
