Objective To analyze and discuss the effect of heat preservation on the recovery time of BIS and the concentration of propofol in the recovery period of the elderly patients with general anesthesia in order to provide guidance for clinical treatment.Methods78 elderly patients with general anesthesia were selected as the subjects, and the patients were divided into the control group and the study group with 39 cases in each group.The patients were divided into the control group and the study group.Control group, only to be liquid input and covered by drapes, research group take liquid input and peritoneal flushing fluid heating and heating blanket coverage of insulation measures, were recorded and compared between the two groups from anesthesia began to operation to complete the different time points of esophageal temperature and MAP, and to observe the recovery time of patients and effect compartment concentration differences.ResultsTwo groups at T0, T1 esophageal temperature no significant difference, study group t2-t6 esophageal temperatures were significantly higher than those of the control group (P<0.05), maps of the other two groups at different time points had no significant difference;when two groups of patients with propofol withdrawal BIS values had no significant difference (P<0.05), and in the time of discontinuation BIS is more than or equal to 80 recovery time and effect compartment concentration have significant difference (P<0.05).ConclusionThe surgical treatment of elderly patients with general anesthesia can help maintain the body temperature, shorten the recovery time of BIS and reduce the concentration of propofol in the recovery period.

Objective To investigate the prevalence of CKD in patients underging coronary angiography with suspected coronary heart disease(CHD). Methods A total of 1031patients with suspected CHD undergoing coronary angiography in Zhongda Hospital from December 2008 to October 2009 were enrolled in the study.The prevalence of CKD and associated risk factors were analyzed.GFR Wag estimated with MDRD equation.CKD was deftned as eGFR<60branches of coronary artery was considered as CHD. Results The mean age of patients were (64.37±11.02)years.There were 543 males and 488 females,including 551 patients with CHD and 134 patients with CKD(13%).Patients with CHD had a significantly higher prevalence of CKD compared with patients without CHD(18.33%vs 6.88%,P<0.01).With the increasing number of stenosis coronary vessels(n=0,1,2,3),eGFR was declined[(84.25±19.00),(81.61±23.92),increased(0.42%,0.82%,1.96%,3.25%,P=0.006),and the prevalence of CKD increased (6.88%,13.11%,21.57%,23.38%,P<0.01).Logistic regression analysis indicated that increasing age(OR 1.094,95%C/1.068 to 1.120),increasing number of stenosis coronary vessels(OR 1.288,95%CI 1.074 to 1.543).hypertension(OR 1.974,95%CI 1.082 to 3.603),cardiac systolic insufficiency(OR 3.183,95%CI 1.696 to 5.972),and hyperuricemia(OR 5.366,95%CI 3.224 to 8.9311 were risk factors for CKD. Conclusions The prevalence of CKD in patients with CHD diagnosed by coronary angiography is quite high.Aging,elevated number of stenosis coronary vessels,hypertension,cardiac systolic insufficiency and hyperuricemia are important risk factors for angiographic patients with CKD.

BACKGROUND: Epidermal growth factor can inhibit gastric acid secretion, promote the healing from the ulcer, protect mucous membrane, and enhance the growth and proliferation of mucous membrane cells of the gastrointestinal tract.OBJECTIVE: To investigate the effect of epidermal growth factor at different doses on the barrier function of the intestinal mucous membrane in rats after radioactive damage.DESIGN: A randomized controlled trial.SETTING: Department of Clinical Trophology, First Affiliated Hospital and College of Public Health.MATERIALS: The experiment was completed at the Public Health Department of Xinjiang Medical University and the First Affiliated Hospital of Xinjiang Medical University from August 2001 to May 2003. Totally 80 newborn Wistar rats, half male and half female, were involved in the study.METHODS: Wistar rats were randomly divided into the control groups(positive and negative) and intervention groups(30 μg/kg, 20 μg/kg, 10 μg/kg) with 16 rats in each group and half male and half female. The models were made by a single radiation of 9.5Gy on the abdomen except for the negative control group. Epidermal growth factor was injected subcutaneously once per day for intervention. Eight days later, the body mass, food intake, efficiency of food utilization were observed and the morphology of the intestinal mucous membrane was checked.dermal growth factor on the increased body mass, food intake and food intake observation of the intestinal mucous membrane under the optic microscope and the electric-microscope.group of rats with epidermal growth factor of 30, 20, 10 μg/kg and the intake of the female and male rats in the group with epidermal growth factor of 30, 20, 10 μ g/kg was significantly different compared with that of the rats in the negative control group( P ＜ 0.05), while there was no significant under the optic microscope and electric microscope showed that when epidermal growth factor was administrated, epidermal growth factor could apparently improve the intestinal mucosal barrier function with the increase of the dose, especially in the group with epidermal growth factor of 30 μ g/kg,which indicates that epithelial cells were increased obviously and cup shaped cells were also increased.CONCLUSION: Epidermal growth factor might not affect the body mass,food intake and efficiency of food intake of the rats, but large doses of epidermal growth factor can improve the morphology of the intestinal mucous membrane and promote the proliferation and repairs.

BACKGROUND: Both hydroxyapatite (HA) and large diameter TiO2 nanotubes have excellent biocompatibility, but bone-forming ability of nano-HA (nHA) deposited large diameter TiO2 nanotubes is rarely reported.OBJECTIVE: To evaluate the bone-forming ability of nHA/large-diameter TiO2 nanotube composite coating.METHODS: Large-diameter TiO2 nanotubes were prepared by anodic oxidation method, and then nHA was electrochemically deposited on the surface of TiO2 nanotubes. Preosteoblasts MC3T3-E1 were co-cultured with the nHA/large diameter TiO2 nanotube composite, pure titanium and TiO2 nanotube coatings, respectively. At 0.5, 1, 2 hours after culture, the initial cell adhesion was observed. At 1, 3, 5 day after culture, cell proliferation was assessed. At 2 days after culture, cell morphology was observed. At 3 and 7 days after osteogenic induction, intracellular alkaline phosphatase activity was detected. At 14 days after osteogenic induction, mineralization of extracellular matrix was detected.RESULTS AND CONCLUSION: (1) After 2 hours of culture, the number of adherent cells on the composite coating was significantly lower than that on the TiO2 nanotube coating (P < 0.05), but slightly higher than that on the pure titanium coating with no statistical difference. (2) After 1, 3, 5 days of culture, the cell proliferation on the composite coating was significantly lower than that on the TiO2 nanotube coating (P < 0.05), but slightly higher than that on the pure titanium with no statistical difference. (3) The cells on the pure titanium showed a spindle-shape, while those on the TiO2 nanotube coating processed filopodia. The cells on the composite coating showed polygonal shape with a larger number of filopodia. (4) The intracellular alkaline phosphatase activity of the composite coating group was significantly higher than that of the pure titanium group and TiO2 nanotube group. The trend of mineralization of extracellular matrix was ranked from high to low: the composite coating group > TiO2 nanotube group > pure titanium group. To conclude, the nHA/large diameter TiO2 nanotube composite coating not only has good biocompatibility, but also has the ideal ability to promote bone formation.

A sandwich ELISA kit for detecting HCV-core Ag was developed by using four strains of anti-HCV-core Ag McAb. One hundred and twenty five serum specimens with increased ALT but negative for anti-HCV, anti-HIV, and anti-Tp tests were tested. Results Nine of the 125 specimens were positive for HCV-core Ag. Conclusion The double sandwich ELISA kits for detecting HCV-core Ag may be useful for the early diagnosis of hepatitis C .

Objective To investigate the safety and effectiveness of different intravenous anesthesia methods for pediatric ERCP . Methods Data of 45 children undergoing ERCP at the Affiliated Hangzhou Hospital of Nanjing Medical University from August 2013 to July 2016, including intravenous anesthesia,the procedure of ERCP, adverse reactions and the waking time were retrospectively studied. Results A total of 45 patients in two groups under intravenous anesthesia successfully underwent ERCP . Seventeen patients ( 37. 8%) whose body weights were over 20 kg and the duration of surgery was predicted less than 30 minutes received deep sedation without airway intubation. Twenty?eight patients ( 62. 2%) with an initial weight of less than 20 kg and the duration of surgery was predicted more than 30 minutes received general anesthesia with airway intubation. In patients with deep sedation, the mean time of waking was 7. 2±6. 3 minutes, body movement reaction occurred in 1 case ( 5. 9%) and with transient decreasing of pulse blood oxygen ( beyond 95%) occurred in 2 cases ( 11. 8%) . In patients receiving endotracheal anesthesia with intubation, the mean waking time was 10. 5±8. 7 minutes without adverse reactions associated with anesthesia. Conclusion Both deep sedation and general anesthesia with airway intubation are safe for pediatric ERCP. However, general anesthesia with airway intubation is an ideal method ensuring the airway safety and oxygen supply for children less than 20 kg undergoing first?time ERCP or the duration of surgery lasting over 30 minutes.

Objective:To investigate the analgesic efficacy of dexmedetomidine combined with dizosine after lumbar internal fixation and its effects on hyperalgesia.Methods:Seventy-two patients who underwent lumbar internal fixation in General Hospital of Armed Police and Marine Police between April 2018 and June 2019 were included in this study. They were randomly assigned to undergo either flurbiprofen axetil and dizosine administration (control group) or dexmedetomidine and dizosine (observation group) for postoperative analgesia. Mechanical pain, degree of postoperative pain, and incidence of complications were recorded in each group.Results:At 6, 24 and 48 hours after surgery, peri-wound pain threshold in the observation group was (119.52 ± 20.42) points, (120.19 ± 17.44) points, (120.94 ± 20.73) points, respectively, which were significantly higher than (108.42 ± 15.24) points, (107.63 ± 16.83) points, (108.47 ± 17.82) points in the control group ( t = 0.01, 0.00, 0.01, all P < 0.05). At 24 and 48 hours after surgery, forearm pain threshold in the observation group was (109.93 ± 15.87) points and (110.79 ± 22.85) points, respectively, which were significantly higher than (97.07 ± 16.49) points and (95.63 ± 24.06) points ( t = 3.37, 2.74, both P < 0.05). There was no significant difference in Ramsay Sedation Scale score between the two groups ( P > 0.05). There was no significant difference in the dose of dizosine used within 48 hours after surgery between the two groups ( P > 0.05). The incidence of postoperative complications in the observation group was significantly lower than that in the control group [8.33% (3/36) vs. 27.78% (10/36), χ2 = 4.60, P < 0.05]. Conclusion:Dexmedetomidine combined with dizosine exhibits obvious analgesic efficacy after lumbar internal fixation. The combined therapy can effectively prevent hyperalgesia with a low incidence of comphications.

OBJECTIVETo study the relationship between occupational stress and psychological health state among oil workers.

METHODS1,230 oil workers in 122 work types of oil industry were selected and written occupational stress questionary(OSQ) and symptom check list (SCL-90).

RESULTSPetroleum workers' psychological health states were poor with increasing occupational stress degree. The scores in physical symptoms(1.87 +/- 0.80, 1.72 +/- 0.70), depression(1.74 +/- 0.76, 1.62 +/- 0.67), horror(1.48 +/- 0.65, 1.39 +/- 0.55) in the high and medium stress group were obviously higher than those in low stress group(1.55 +/- 0.61, 1.43 +/- 0.54, 1.28 +/- 0.46, respectively, P < 0.05). The score of mood state in the high and medium stress group was obviously higher than that in low stress group(P < 0.05). Psychological health states and mood state in the petroleum workers with short service length are significantly poorer than that with long service length(P < 0.01).

CONCLUSIONOccupational stress should affect psychological health state of petroleum workers.

Objective: To explore relationship between screen time and myopia in children aged 11-14 years in China. Methods: The data were extracted from "National Nutrition and Health Systematic Survey and Application for 0-18 Years Old Children". A total of 12 397 children aged 11-14 years old from 14 provinces and 28 districts/counties in seven regions of China were surveyed by using multi stage stratified random sampling method. Daily screen time and visual acuity information were collected through a questionnaire. Results: The myopia rate of 11-14 years old children in China was 45.0%, among which the rate of girls was higher than that of boys, and the rate of urban was higher than that of rural, and it increased with age ( χ 2=178.82,79.25, 495.96 , P <0.01). The daily screen time median of 12 397 children was 40.0 minutes, with boys(40.0 min) longer than girls( 35.0 min ) and urban children(40 min) longer than rural children(33.0 min) ( χ 2=20.86，102.68， P <0.01). The myopia rate of boys ( 42.5 %) with daily screen time greater than or equal to 60 minutes was higher than that of boys (36.4%) with daily screen time less than 60 minutes, and the myopia rate of girls (55.6%) with daily screen time greater than or equal to 60 minutes was higher than that of girls (48.0%)( χ 2=23.62，34.15， P <0.01). After adjusting for age, gender, region, time of medium and high intensity physical activity, intake of sugary food and sugary beverages, daily sleep time, multivariable Logistic regression model showed that girls with daily screen time greater than or equal to 60 minutes ( OR=1.14, 95%CI =1.03-1.27) had a higher risk of myopia than those with less than 60 minutes. After adjusting for confounding factors, there was no correlation between daily screen time and the degree of myopia in boys or girls( P >0.05). Conclusion Daily screen time greater than or equal to 60 minutes may be a risk factor for myopia in girls aged 11 to 14 years old. Given the complexity of the factors that affect vision, researches are needed to examine the relationship between screen time and myopia.
