Objective To investigate the therapeutic effects of two parenteral nutrition (PN)methods in preterm infants. Methods Forty-two preterm infants who could not tolerate full enteral feeding were randomly divided into two groups. Twenty-two cases of the experimental group started to receive amino acids (AA) by 1.0 g/(kg·d) within 24 h after birth. Then AA was increased by 1.0 g/(kg·d)each day to maximum of 3.0 g/(kg·d)The dose and add method of intralipid was given alike AA within 48 h. Complete PN was achieved 5 d after birth. Twenty cases of the control group started to receive AA by 0. 5 g/(kg·d) ,and then increased by 0. 5 g/(kg·d) each day to maximum of 3.0 g/(kg ·d). The dose and add method of intralipid was given alike AA after 72 h. Complete PN was achieved at 8 or 9 d after birth. The feeding results was observed,the blood biochemistry was monitored at 72 h and 10 d after birth,and the incidence of complication was recorded. Results In comparison with the control group, time returning to birth weight, the weight loss rate, PN time and time returning to full enteral feeding were shorter in the experimental group (P ＜0. 01). There were no significant differences in the blood glucose,total bilirubin, urea nitrogen,carbon dioxide combining power,total cholesterol and the incidence of complication between the two groups (P ＞ 0. 05). Conclusion Quantity sufficient and early parenteral nutrition can be tolerated by preterm infants within 24 h after birth.

Objective To investigate the in vitro effects of various antibiotics (spectinomycin, ceftriaxone, erythromycin, ofloxacin and doxycycline) against 12 isolates of C. trachomatis. Methods Minimal inhibitory concentrations (MICs ) and fractional inhibitory concentrations (FICs) of the antimicrobials against all C. trachomatis were calculated. Checkerboard method was used for the determination of FICs and Ridit test for the comparison of the interactions among the various combinations. Results No difference was observed in most of the combinations. No antagonism was found in all except for ceftriaxone-doxycycline combination. Synergism was observed in 42% (5 of 12) and 50% (6 of 12) of the chlamydial isolates for erythromycin-spectinomycin and doxycycline-spectinomycin combination, respectively. No significant difference was observed among triple combinations with spectinomycin or with ceftriaxone. When interactions of erythromycin, ofloxacin and doxycycline with spectinomycin were compared to those with ceftriaxone respectively, both interactions of erythromycin (U = 2.46, P = 0.014) and doxycycline (U = 2.83, P = 0.002) were more synergistic with spectinomycin than those with ceftriaxone. Conclusions This study indicates that the combination of spectinomycin with erythromycin or doxycycline is more effective against C. trachomatis than that of ceftriaxone. Therefore, spectinomycin rather than ceftriaxone might be recommended in the dual therapy against C. trachomatis and N. gonorrhoeae.

Objective : To investigate the status of occupational stress and analyze its influencing factors among frontline employees working in a chemical fiber manufacturing enterprise, so as to provide insights into the development of occupational stress interventions. Methods : The frontline employees working in a chemical fiber manufacturing enterprise were selected as the study subjects using a cluster sampling method in October 2018. The status of occupational stress was investigated using the Chinese version of the effort-reward imbalance ( ERI ) questionnaire. The influencing factors for occupational stress were identified using a multivariable logistic regression model. Results : A total of 1 780 questionnaires were sent out, and 1 115 valid ones ( 62.64% ) were recovered. Among the 1 115 respondents, there were 427 men ( 38.30% ) and 688 women ( 61.70% ), and 71.22% were at ages of 21 to 39 years. There were 561 respondents with < 1 year of service ( 50.31% ), and the longest length of service was 11 years. In addition, there were 1 069 respondents ( 95.87% ) exposed to high noise, and 346 respondents ( 31.03% ) were diagnosed at a high occupational-stress state and 769 ( 68.97% ) at a low state. Multivariable logistic regression analysis identified 5 years or longer of service ( OR=1.540, 95%CI: 1.057-2.245 ) and exposure to high noise ( OR=1.917, 95%CI: 1.004-3.659 ) as risk factors for occupational stress among frontline employees in the chemical fiber manufacturing enterprise. Conclusions There are 31.03% of frontline employees at a high occupational-stress state in the chemical fiber manufacturing enterprise, and a high occupational-stress state is associated with exposure to high noise and 5 years or longer of service.

Objective : To examine the diagnostic and prognostic value of long non-coding RNA (lncRNA) JPX in mesothelioma, so as to provide insights into diagnosis and prognosis of mesothelioma. Methods: Patients with clinically definitive diagnosis of mesothelioma from 2015 to 2019 that were sampled from asbestos processing plants in Zhejiang Province from 2015 to 2019 were recruited in the mesothelioma group, while healthy residents without asbestos exposure or asbestos-related diseases in the same area served as controls. Participants' demographics, pathologic diagnosis and imaging features were collected, and the expression of blood lncRNA JPX was detected using lncRNA microarrays. The diagnostic value of lncRNA JPX for mesothelioma was evaluated using the receiver operating characteristic (ROC) curve, and the correlation between lncRNA JPX expression and prognosis was examined among mesothelioma patients using survival analysis. Results: There were 17 subjects in the mesothelioma group, with a mean age of (65.71±8.36) years, and 34 subjects in the controls, with a mean age of (64.24±8.70) years. LncRNA microarray detected significantly high lncRNA JPX expression in mesothelioma patients, and higher blood lncRNA JPX expression was detected in the mesothelioma group than in the control group [median (interquartile range), 1.10 (1.31) vs. 0.89 (0.54); t'=-2.300, P=0.034]. The area under the ROC curve was 0.673 (95%CI: 0.507-0.839, P=0.046), and if the cutoff was 1.759, the sensitivity and specificity were 35.3% and 100.0%, respectively. Survival analysis showed no significant difference in the survival rate of mesothelioma patients between the high lncRNA JPX expression group and the low expression group (χ2=0.212, P=0.645). Conclusions LncRNA JPX overexpression is detected in the blood of patients with mesothelioma, and lncRNA JPX expression presents a diagnostic value for mesothelioma; however, it shows little prognostic value for mesothelioma.
