Methods For the same patients and in the nearest time interval, the two methods mentioned above were used to mea-sure the axillary temperature. Totally 782 patients were measured. Results There was no statistical sig-nificance between the measuring results of the two methods. Conclusions Axillary temperature measure-ment used in clinic should be standardized so that more scientific data will be got,effective operation and humanized service can be realized.

Objective To investigate the change in the function of the motor nerve fibers of the sciatic nerve of rat following injection of different neurolytic drugs. Methods Thirty-five SD rats weighing 350-380 g were randomly divided into 7 groups ( n = 5 each): group C received normal saline; group Ad adriamycin 5 mg/ml;group Aa anhydrous alcohol; group Pg1 8% phenol-glycerol; group Pg2 10% phenol-glycerol; group Pg3 12% phenol-glycerol and group Ci cidomycin 4000 U/ml. 0.2 ml of the different neurolytic drugs was injected at the points where the branches of the sciatic nerve entering semi-membranous and adductor magnus muscles. The action potential and conduction velocity of motor and sensory nerve fibers were measured at 21 d after injection. Results The conduction velocity of sensory nerve fibers was 0 in each group. The conduction velocity and action potential of the motor nerve fibers were significantly decreased in group Ad, Aa, Pg1, Pg2, Pg3 and Ci as compared with group C (the control group). The action potential and the conduction velocity were significantly higher in group Ad than in other neurolytic drug groups. The potential and the conduction velocity were the lowest in group Aa and Pg3.The conduction velocity in group Pg1, Pg2, Ci was comparable. Conclusion 5% adriamycin seems to be a better neurolytic drug with less interference with function of motor never fibers.

Aim To investigate the inhibitory effect of paeonol (Pae) on the human esophageal cancer cell line Eca-109 in vitro and in vivo and its effect on apoptosis.Methods Cytotoxic effect of Pae on Eca-109 cells cultured in vitro was measured by MTT assay.Anti-tumor activity was performed on BALB/c nude mice xenografts model.The morphologic changes of tumor tissue were observed under light microscope and transmission electron microscope.The apoptosis index was assessed by TUNEL.Results Pae had significant in- hibitory effect on the proliferation of Eca-109 cells,and the IC50 value was 0.342 mmol?L-1.In the model of human esophageal cancer xenografts in BALB/c nude mice,the inhibitory rates of Pae group (25、50、100、200 mg?kg-1) were 10.67%、23.54%、27.91% and 34.46% respectively.In vivo administration of Pae 100 mg?kg-1 combined with cisplatin 5 mg?kg-1 resulted in a significant inhibition of Eca-109 tumor growth with the inhibitory rate of 77.91%,compared with cisplatin used alone (58.71%).The more apoptotic tumor cells could be seen under light microscope in every theraperutic groups than those in control.Changes of ultrastructure of tumor cells including concentration and side accumulation of the nuclear chromatin,and the fragmentation of the nuclear was observed under transmission electronic microscope.Apoptosis body was also found.The apoptosis indexes of every theraperutic groups were significantly different from the control.Conclusion Pae can inhibit the cell growth and induce apoptosis in human esophageal cancer cell line Eca-109 in vitro and in vivo.

Objective:To analyze the risk factors of non-alcoholic fatty liver disease (NAFLD) among elderly residents in the community.Methods:A total of 1 894 patients aged 60-75 years with NAFLD visiting general practice clinic from March 2016 to March 2018 were enrolled in the study; 1 894 age and sex-matched subjects without NAFLD served as the control group. The data of gender, age, smoking status,body mass index (BMI), waist circumference, blood pressure, blood biochemistry,past medical history and other clinical and laboratory testing were collected in the two groups.

Conclusion:The factors associated with NAFLD are complicated; and corresponding measures targeting the risk factors should be taken to reduce the occurrence and development of NAFLD among elderly people in the community.

OBJECTIVE:To investigate the effectiveness and economics of 10 mg/d rosuvastatin and 20 mg/d atorvastatin in the treatment of hyperlipidemia (HLP). METHODS:The information of 180 HLP patients selected from Tianmen Municipal First People's Hospital during Mar. 2015-Feb. 2016 were divided into group A and B according to medication regimen,with 90 cases in each group. Group A was given Atorvastatin calcium tablet 20 mg,qd;group B was given Rosuvastatin calcium tablet 10 mg,qd. Treatment course of 2 groups lasted for 8 weeks. Blood lipid indexes before and after treatment,lipid-lowering efficacy,the rate of qualified blood lipid and the occurrence of ADR after treatment were compared between 2 groups. Cost-effectiveness analysis was adopted for economic evaluation. RESULTS:Before treatment,there was no statistical significance in the levels of blood lipid in-dexes between 2 groups (P>0.05). After treatment,TC and LDL-C levels of 2 groups were significantly lower than before treat-ment,and those of group B were significantly lower than those of group A,with statistical significance(P<0.05). Total response rate of lipid-lowering in group B(97.78％)was significantly higher than group A(86.67％),and the rate of qualified blood lipid (66.67％)was also significantly higher than group A(51.11％),with statistical significance(P<0.05). There was no statistical significance in the incidence of ADR between 2 groups (P>0.05). The costs of group A and B were 488.32,436.24 yuan,and cost-effectiveness ratios were 5.63,4.46;incremental cost-effectiveness ratio was -4.69. The plan of group B had cost-effective-ness advantage. The results of cost-effectiveness analysis were supported by sensitivity analysis. CONCLUSIONS:In the view of short-term efficacy,10 mg/d rosuvastatin plan is better than 20 mg/d atorvastatin plan in lowering lipid and has cost-effectiveness advantage,and both have similar safety.

BACKGROUND/AIMS: This animal study aimed to define the underlying cellular mechanisms of intestinal barrier dysfunction. METHODS: Rats were fed 4% with dextran sodium sulfate (DSS) to induce experimental colitis. We analyzed the sugars in 24-hour urine output by high pressure liquid chromatography. The expression of claudins, mannan-binding lectin (MBL), and MBL-associated serine proteases 2 (MASP-2) were detected in the colonic mucosa by immunohistochemistry; and apoptotic cells in the colonic epithelium were detected by the terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick-end labeling method assay. RESULTS: The lactulose and sucralose excretion levels in the urine of rats with DSS-induced colitis were significantly higher than those in the control rats. Mannitol excretion was lower and lactulose/mannitol ratios and sucralose/mannitol ratios were significantly increased compared with those in the control group (p<0.05). Compared with the controls, the expression of sealing claudins (claudin 3, claudin 5, and claudin 8) was significantly decreased, but that of claudin 1 was increased. The expression of pore-forming claudin 2 was upregulated and claudin 7 was downregulated in DSS-induced colitis. The epithelial apoptotic ratio was 2.8%+/-1.2% in controls and was significantly increased to 7.2%+/-1.2% in DSS-induced colitis. The expression of MBL and MASP-2 in the intestinal mucosa showed intense staining in controls, whereas there was weak staining in the rats with colitis. CONCLUSIONS: There was increased intestinal permeability in DSS-induced colitis. Changes in the expression and distribution of claudins, increased epithelial apoptosis, and the MASP-2-induced immune response impaired the intestinal epithelium and contributed to high intestinal permeability.

Objective:To investigate the effects of breast milk to total milk intake ratio during hospitalization on the duration of antibiotic therapy in preterm infants less than 34 weeks of gestation.Methods:Clinical data of preterm infants ( n=1 792) less than 34 gestational weeks were retrospectively collected in 16 hospitals of Jiangsu Province Neonatal-Perinatal Cooperation Network from January 1, 2019, to December 31, 2021. The days of therapy (DOT) were used to evaluate the duration of antibiotic administration. The median DOT was 15.0 d (7.0-27.0 d). The patients were divided into four groups based on the quartiles of DOT: Q 1 (DOT≤7.0 d), Q 2 (7.0 d27.0 d) groups. According to the breast milk intake ratio (breast milk intake to total milk intake during hospitalization×100%), they were also divided into four groups: very-low-ratio breastfeeding group (breast milk intake ratio≤25%), low-ratio breastfeeding group (25%75%). Univariate analysis ( Chi-square test and Kruskal-Wallis rank-sum test) was used to analyze the factors influencing DOT. Spearman correlation analysis and trend Chi-square test were used to explore the relationship between breast milk intake ratio and DOT. After using multiple imputations to address missing data, two models were constructed after adjusting for different factors, and multinomial logistic regression model was applied to evaluate the effects of the breast milk intake ratio on DOT. Finally, sensitivity analysis was conducted to assess the stability of the models. Results:(1) Of the 1 792 preterm infants, there were 507 (28.3%) in the Q 1 group, 422 (23.5%) in the Q 2 group, 438 (24.4%) in the Q 3 group and 425 (23.7%) in the Q 4 group. (2) The median values of DOT in the very-low-ratio, low-ratio, medium-ratio and high-ratio breastfeeding groups were 20.0 d (11.0-31.0 d), 20.0 d (11.0-32.0 d), 13.0 d (6.0-25.8 d) and 10.0 d (4.0-21.0 d), respectively. Compared with the very-low-ratio and low-ratio breastfeeding groups, the medium-ratio and high-ratio breastfeeding groups had shorter DOT (all P<0.05). (3) After adjusting for factors with P<0.1 (prenatal glucocorticoid exposure, antimicrobial use within 24 h before delivery, gestational age at delivery, birth weight, Apgar score≤7 at 1 min, neonatal respiratory distress syndrome, infectious pneumonia and early-onset neonatal sepsis) between the DOT quartile groups, it showed that medium-ratio and high-ratio breastfeeding were protective factors in contrast to very-low-ratio breastfeeding in the Q 2, Q 3 and Q 4 groups as compared with the Q 1 group [Q 2 group: OR=0.50 (95% CI: 0.30-0.85) and OR=0.36 (95% CI: 0.26-0.51); Q 3 group: OR=0.31 (95% CI: 0.18-0.55) and OR=0.20 (95% CI: 0.14-0.29); Q 4 group: OR=0.22 (95% CI: 0.12-0.42) and OR=0.17 (95% CI: 0.12-0.26)]. Conclusion:Breast milk intake accounting for over 50% of total milk intake has a positive impact on reducing DOT in premature infants requiring antibiotics, which suggests that breastfeeding should be actively encouraged.
