Objective To explore the effect of meditation training on postoperative pain, anxiety and reduce the incidence of constipation in patients with lower limb fracture. Methods The enrolled 106 patients with lower extremity fractures were randomly divided into the observation group and control group 53 cases respectively according to the odd even method. The control group was implemented with fracture surgery routine care, while the observation group was implemented with meditation training on the basis of the control group, the two groups were compared by postoperative pain score, anxiety, constipation, and satisfaction. Results Before intervention, the postoperative pain Visual Analogue Scale (VAS) scores and anxiety scores of the two groups were not significantly different (P>0.05). After intervention, the postoperative pain scores of observation group and control group were (2.06 ± 0.85) points and (4.15 ± 0.62) points respectively, the difference was statistically significant (t = 4.103, P <0.05). The anxiety scores of observation group and control group were (28.95 ± 3.83) points and (56.13 ± 3.52) points respectively, the difference was statistically significant (t= 2.353, P < 0.05). The first defecation time and the cases number of observation group patients were as follows:day 1st:20.75%(11/53), day 2nd: 52.83% (28/53), day 3rd: 18.87% (10/53), day 4th: 7.55% (4/53). While the data of the control group were day 1st: 1.89% (1/53), day 2nd: 26.42% (14/53), day 3rd 37.74% (20/53), day 4th:33.96%(18/53), the difference between the two groups was statistically significant (χ2=4.022-5.629, P<0.05). The satisfaction of observation group and control group patients were 94.34%(50/53), 77.36%(41/53) respectively, the difference was statistically significant (χ2=4.543, P < 0.05). Conclusions Meditation training can effectively reduce postoperative pain, reduce the incidence of anxiety and constipation, and improve the satisfaction of patients to nursing service, and promote the recovery of patients after surgery.

Objective To explore the difference of sleep quality and the influencing factors in ketamine dependent subjects and methamphetamine dependent subjects.Methods 60 ketamine dependent subjects and 60 methamphetamine dependent subjects with Pittsburgh sleep quality index (PSQI),self-rating depression scale (SDS),self-rating anxiety scale (SAS) were tested.Results Methamphetamine dependent subjects was significantly more likely to elicit poor sleep quality than ketamine dependent subjects (P =0.022).The sleep quality of ketamine dependent subjects had a positive correlation with anxiety(P =0.015),depression(P =0.038),the onset age (P =0.029),and the dose of ketamine use in the last three months (P =0.048),while the sleep quality of methamphetamine dependent subjects had a positive correlation with the total time of ketamine use (P =0.038),anxiety (P =0.041),the dose of ketamine use in the last three months (P =0.011).Conclusion Methamphetamine dependent subjects are prone to a more serious poor sleep quality than ketamine dependent subjects.

Objective To investigate effect of trepibutone tablet combined with ursodeoxycholic acid in treatment of patients with gallstone. Methods 200 cases with gallstone were diagnosed and randomly divided into observation group and control group from February 2013 to February 2014.100 cases in control group were given ursodeoxycholic acid treatment 50 mg/(kg? d),two times per day for six month.On the basis of control group observation group were treated with trepibutone one tablet per day,three times per day,4 weeks for 1 course, 2 weeks of treatment interval between 4 courses, totally for four courses.After treatment, patients were followed up and recorded gallbladder wall thickness, gallbladder functional status. Results After 6 months of treatment in patients with gallbladder wall thickness of observation group ( 2.77 ±0.38 ) mm was superior to control group (3.24 ±0.36)mm(P<0.05).After 6 months of treatment in patients with gallbladder function score of observation group (58.75 ±4.79) was better than control group (53.11 ±5.02) ( P<0.05).Recurrence rate of observation group was 9% better than that of control group 18%(χ2 =3.468,P<0.05)after treatment for 6 months.Conclusion Effect of trepibutone tablet combined with ursodeoxycholic acid in treatment of patients with gallstone is well.There is no obvious side effects during the treatment.

Objecfive To investigate possibihty of monitoring myocardial isehemia by eontinuous EASI 12-lead ST-segment trend analysis during orthopaedic surgery and find its rules.Methods Three hundred and eleven consecutive patients who underwent orthopaedic surgery were monitored bv continuous EASI 12-lead ST-segment analysis during surgery.Results Among 311 patients 81 patients(26.0%) had myocardial ischemic events.The ischemie incidence of general anesthetics WaS signifieantly higher than local anesthetics(the spinal or epidural anesthetics and nerve-block anesthetics)(38.1%vs 23.0%.P＝ 0.01 5).During ischemie events the patients whose heart rate exceeded 90 beat per minute was 71.6% (58/81).Among the 177 isehemie events,the duration ofless than 5 minutes was 79.7%(141/177).ST-seg- ment deviation ofless than 0.15 mV was 71.2%(126/177).Conclusions During orthopaedic surgery EASt 12-lead electrocardiogram is the optimal approach for monitoring myocardial isehemia.The ischemic incidence of general anesthetics is significantly higher than local anesthetics.The myocardial ischemia events correlates with fast heart rate.The intraoperative myocardial ischemia events are more often transient.In most of these ischemic events ST-segment deviation is not very serious.

Objective: To investigate the clinical characteristics, cell morphology, genetics, gene mutations of the patients with chronic neutrophilic leukemia (CNL). Methods: Five CNL patients from the Second Hospital of Shanxi Medical University between May 2011 and May 2017 who conformed to 2016 World Health Organization (WHO) diagnostic criteria were retrospectively analyzed from clinical characteristics, laboratory features and treatment methods. Results: The peripheral blood white blood cell count (WBC) of 5 CNL patients was significantly increased, and the average WBC was 81.26×10⁹/L [(29-217)×10⁹/L]. Morphological analysis of peripheral blood cell showed a sustained increasing number of matured neutrophilia (0.80-0.85). Neutrophil alkaline phosphatase (NAP) activity was increased (144-266). Bone marrow cell morphology typically showed granulocyte proliferation without obvious dysplasia. Gene detection showed 3 patients with CSF3R T618I mutation and 2 patients with JAK2 V617F mutation in 5 WHO-defined CNL patients. Bone marrow biopsy with reticular staining showed that marrow fibrosis (MF) degree in patients with JAK2 V617F mutation (MF≥2) was higher than that in patients with CSF3R T618I mutation(MF<2). Conclusions CNL is a rare type of chronic leukemia, and CSF3R T618I mutation is a specific diagnostic index for CNL. JAK2 V617F mutations alone may be related to myelofibrosis, which remains to be further studied.

Objective To discuss the safety and curative effect of superior rectal artery chemoembolization in treating rectal cancer complicated by hepatic metastasis.Methods A total of 17 patients with rectal cancer complicated by hepatic metastases were treated with hepatic arterial chemoembolization together with subsequent superior rectal artery chemoembolization.Super-selective catheterization of superior rectal artery with a 3-F microcatheter was performed first,which was followed by perfusion of 5-Fu and oxaliplatin through the microcatheter,and then irinotecan and Lipiodol emulsion was injected.Results Technical success was obtained in all 17 patients.In 2-7 days after the treatment,the amount of faeces containing mucus,blood and pus was significantly increased,besides,obvious necrotic tissues could be observed in the faeces in some patients.Among the 3 patients who had complained of abdominal pain,the pain disappeared in 3 days (n=2) or in 5 days (n=1) after the treatment.One week after the treatment,anal pain disappeared in 5 patients and was remarkably improved in 2 patients;tenesmus feeling was significantly relieved in 7 patients although the improvement of tenesmus feeling was not obvious in other 4 patients.During the long period following-up,no intestinal perforation or local infection was observed.Conclusion For the treatment of rectal cancer associated with hepatic metastasis,superior rectal artery chemoembolization is safe and effective.It can quickly cause rectal tumor necrosis,which is an important therapeutic response in treating rectal cancer with comprehensive therapy.

OBJECTIVETo study the respiratory system injury in fur processing environment.

METHODSEnvironmental fungal survey was conducted in the fur processing procedures. Investigation of respiratory symptoms and chest X-ray examination were also carried out in 138 fur processing workers and 40 control workers. At the same time, the serum antibodies to fungi were analyzed by ELISA.

RESULTSFungal number(629-3,681 cfu/m3) in fur processing procedures was much higher than those in the control environment. Cladosporium and Alternaria were the leading strains of fungi in fur processing procedures. The rates of respiratory symptoms(cough, sputum, chest tightness, dyspnea, and fever) in fur processing workers were higher than those in the control workers. The rates of the symptoms in female workers were 37.9%, 28.4%, 10.5%, 22.1%, 4.2%, respectively. Abnormalities of chest X ray were found in 7 workers. The serum antibodies to Cladosporium and Alternaria(A450 nm 0.631, 0.724, respectively) in fur workers were significantly higher than those in the control workers(P < 0.05). The positive rates of the antibodies to Cladosporium and Alternaria(44.2%, 42.8%) were significantly higher than those in the control workers(P < 0.01).

CONCLUSIONCladosporium and Alternaria may be the pathogens of occupational respiratory diseases in fur processing workers.
