Objective? To explore the effects of clinical nursing pathway chart in rehabilitation of perioperative patients with thoracoscope pneumonectomy. Methods? From January 2017 to December 2018, we selected 105 patients with thoracoscope pneumonectomy. All of the patients were randomly divided into observation group (n=52) and control group (n=53). Observation group carried out perioperative nursing according to the clinical nursing pathway chart, while control group implemented routine nursing. We compared the pain, respiratory recovery effect and treatment compliance of patients after surgery. Results? The scores of pain of patients in observation group 24 and 48 hours after surgery was (4.85±0.42) and (3.74±0.30) respectively lower than those in control group with statistical differences (t=5.594, 13.105;P＜ 0.05). Five days after surgery, the blood oxygen saturation of observation group and control group was (95.78±0.29)% and (91.73±0.33)% respectively with a statistical difference (t=4.603, P＜ 0.05). Patients with the high level of treatment compliance in intraoperative period accounted for 73.08% in observation group and 45.28% in control group with a statistical difference (Z=4.891,P＜0.05). Conclusions? Application of clinical nursing pathway chart in rehabilitation of perioperative patients with thoracoscope pneumonectomy relieves the postoperative pain and improves rehabilitation effects as well as treatment compliance.

Objective To observe the effects of enhanced exercise and combined vitamin D and calcium supplementation on muscular strength and fracture occurrence in postmenopausal women with a high risk of osteoporosis.Methods Totally 614 postmenopausal women at high risk factors of osteoporosis were enrolled in Dongcheng district of Beijing and randomized into four groups:group A(control group,n=173),group B(regular Tai Chi exercise,n=171),group C(calcium 600 mg/d+VitD800 U/d,n=139),and group D[calcium 600 mg/d+25 hydroxyl vitamin D(25OHD) 0.25 μg/d,n=131].Muscular strength was measured at baseline and one and two years after intervention.Bone turnover markers were measured at baseline and during the two-year follow-up.Falls and fractures were recorded.Results The incidence of 25OHD<50 nmol/L was approximately 92.6%.During the follow-up,the left grip strength decreased significantly two years after intervention(t=-3.252,P=0.001)in group A.Right grip strength decreased significantly in group B(t=2.460,P=0.015)while left grip strength improved significantly in group C(t=-2.051,P=0.043)one year after intervention.In group D,muscular strength in both 12-month and 24-month did not change compared with baseline(both P>0.05).Furthermore,serum procollagen type I N-terminal propeptide elevated significantly in group A(t=-2.962,P=0.004),group B(t=-2.888,P=0.005),and group C(t=-2.441,P=0.016),whereas β-C-terminal telopeptide of type I collagen decreased significantly in group B(t=2.285,P=0.024)and group D(t=2.596,P=0.011)two years after intervention.Conclusion Enhanced exercise and combined calcium vitamin D supplementation may help sustain muscle strength in postmenopausal women,while calcium and vitamin D supplementation may improve muscular strength within a short period of time.

Objective:To establish a method for determining methoxyacetic acid in urine by pre-column derivatization-liquid-liquid microextraction coupled with gas chromatography (GC) .Methods:Phosphate buffer solution, tert-butoxyacetic acid (internal standard) and pentafluorobenzyl bromide (derivative) were added to the urine sample. After derived in a water bath at 90 ℃ for 40 min, the mixture was cooled and filtered, then the dichloromethane was used as an extractant. After being shaken and centrifuged, the lower organic phase was sucked and injected into a gas chromatograph, separated by a DB-5 capillary column, and detected by an ECD detector.Results:The linear range of the method was 0.6~60.0 mg/L with the correlation coefficients ( r) above 0.999. The average recovery was76.6%~110.7%, the inter-day precision was 8.00%~8.82%, and the detection limit was 0.13 mg/L. Conclusion:The method was founded to be high sensitivity, low organic reagent usage and green. So it is suitable for the detection of methoxyacetic acid in urine of occupational exposure to ethylene glycol monomethyl ether.

Objectives To observe the changes of autophagy of acinar cells in hypertriglyceridemia (HTG) associated acute necrotic pancreatitis(ANP) rats,and investigate the effects of HTG on autophagy and AP. Methods Forty SD rats were randomly divided into 4 groups using random number method, including control group,ANP group,hyperlipemia(HL) group,hyperlipidemia associated acute necrotizing pancreatitis (HANP) group. Control group and ANP group were fed with normal diet for 2 weeks,while the rats in HL and HANP group were fed with a high-fat diet for 2 weeks,and after the blood collection ANP and HANP rats were induced by 3.5% sodium taurocholate retrograde injection into the pancreaticobiliary duct to establish the ANP model. Rats in control group and HL group were intraperitoneally injected with equal volume of normal saline solution. ALL rats were sacrificed at 48 h after the model establishment. Serum triglyceride (TG), total cholesterol (TC) and serum amylase levels were measured; pancreatic tissue was histologically examined and scored; Transmission electron microscope were used to observe the intracellular ultrastructure changes and calculate the number of autophagosome and autophagic lysosome;the expressions of autophagy related proteins such as LC3,LC3Ⅱ, LC3Ⅰ, p62 and Lamp-2 were determined by Western-blot. Results After 2-week high fat diet, serum levels of TG and TC in HANP and HL groups were obviously higher than those in the control and ANP group;Serum amylase levels in HANP group and ANP group were higher than the control and HL group,and the differences were statistically significant (all P<0.05). Transmission electron microscope showed that the number of autophagosomes in ANP group was significantly higher than those in other three groups and the difference was statistically different(all P<0.05);and the autophagy activity in HANP group was impaired compared with ANP group. Compared with the control group, in ANP group the protein expressions of LC3 Ⅱ/Ⅰ ratio and p62 in pancreatic tissue were up-regulated (2.11 ± 0.03 vs 1.70 ± 0.08, 9 420 ± 624 vs 4 973 ± 577),but LAMP-2 was down-regulated(20 533 ± 578 vs 23 231 ± 1 155). Compared with ANP group,the proteins expression levels of LC3Ⅱ/Ⅰand p62 in HANP group was obviously decreased (20 533 ± 578 vs 23 231 ± 1 155), and the difference was statistically significant (all P<0.05). Conclusions Hypertriglyceridemia can worsen the pathology injury of AP,and the mechanism may be related to the decreased autophagy related proteins LC3Ⅱ/Ⅰ and p62 and decreased number of autophagosome.

Objective:To describe the status and influencing factors of the empowerment of caregivers after gastrointestinal tumor.Methods:From March 2019 to October 2019, using convenience sampling method, 124 pairs of gastrointestinal tumor patients and caregivers who were hospitalized in the general surgery and anorectal surgery of the department of Shandong Tai′an City Central Hospital and the Second Affiliated Hospital of Shandong First Medical University were selected as the subjects. A general information questionnaire, Main Caregivers′Empowerment Measurement were used as research tools. To investigate the empowerment ability of caregivers of patients with gastrointestinal tumors after operation.Results:The total caregiver′s empowerment score was 168.81 ± 19.49. The scores of each dimension ranged from high to low: relationship with caregivers (3.83 ± 0.43), expectation of care outcomes (3.80 ± 0.43), awareness of caregiving roles (3.70 ± 0.51), caregivers′ subjectivity (3.37 ± 0.60), caregiving beliefs (3.34 ± 0.67), caregiving knowledge and skills (3.27 ± 0.73), personal resources (2.94 ± 0.65), goodwill caregiving (2.85 ± 0.65) , the scruples around (2.75 ± 0.88). Multiple linear regression results showed that, patient gender, whether the disease is first attack, whether the patient is aware of the disease, the caregiver marriage, and the caregiver working status were the influencing factors of the caregiver′s empowerment ability after gastrointestinal tumor operation ( t values were -8.15-8.72, R2=0.62, all P<0.05). Conclusions:There is room for further improvement in the empowerment of caregivers after gastrointestinal tumor surgery, especially in personal resources, goodwill care and scruples around. The results suggest that medical staff should guide caregivers to emancipate their minds, enhance the breadth of empowerment, and promote self care and fast rehabilitation of patients.
