OBJECTIVE:To investigate the perioperative prophylactic use of antibiotics in thoracic surgery department of 7 hos-pitals in Nantong city,and to provide reference for rational drug use in clinic. METHODS:In retrospective study,6652 dis-charged patients with thoracic surgery were selected from 7"third-level hospitals"of Nantong city during 2015-2016. The gender, age,length of stay,preoperative medication,medication timing,classification of incision,operation time,drug name,usage and dosage,route of administration,drug combination and prognosis were analyzed statistically. According to the relevant regulations of special rectification and the principle of perioperative antibiotics use,the rationality of antibiotics use was evaluated. RE-SULTS:Among 6652 patients,there were 2761 cases of typeⅠincision and 3891 cases of typeⅡincision. All of them used anti-biotics. Primary prophylactic time was 0.5-2 h before operation in 5282 cases,accounting for 79.40%;1370 cases were given medicine more than 2 h before surgery or after surgery,accounting for 20.60%. Totally 1070 cases received prophylactic medica-tion within 48 h,accounting for 16.09%;5582 cases received prophylactic medication more than 48 h,accounting for 83.91%. A total of 5702 cases were given only one antibiotic,and 950 cases received two-drug combination. A total of 6342 patients used an-tibiotics irrationally,accounting for 95.34%. Eight categories 15 kinds of antibiotics were involved. β-lactam/β-lactamase inhibi-tors,fluoroquinolones and cephalosporins were mostly used. CONCLUSIONS:After the implementation of special rectification, there are still many irrational phenomena in the prophylactic use of antibiotics in thoracic surgery department of 7 hospitals in Nan-tong city. Some indexes exceed the national standard and still need to be further managed and improved.

Objective:To investigate the clinical features of pertussis in children and analyze the risk factors of severe pertussis.Methods:The clinical data of 248 children with pertussis hospitalized in Hunan Children′s Hospital from March 2018 to March 2022 were analyzed retrospectively.According to the age at admission, the patients were divided into two groups: ≤3 months and > 3 months.According to the patient′s condition, they were classified into ordinary group and severe group.According to the pathogens detected, the children were divided into single infection group and mixed infection group.The independent sample t-test, chi- square test were used to analyze the clinical indexes of the infants in above groups. Results:(1)Of 248 hospitalized children with pertussis, 204 cases (82.2%) were less than 1 year old, 92 cases (37.0%) had contact with a coughing family member before, and 169 cases (68.1%) were unvaccinated.Among 248 children, 193 cases (77.8%) had an elevated white blood cell count, and 145 cases (58.4%) had mixed infections.The most common pathogen was respiratory syncytial virus [29/248(11.6%)]. About 173 cases (69.7%) had concurrent pneumonia, and 35 cases (14.1%) had pulmonary consolidation.(2)Compared with the group > 3 months of age, more patients in the group ≤3 months of age had contact with a coughing family member before, and suffered from cyanosis, dyspnea, respiratory failure, heart failure and pertussis encephalopathy ( χ2=4.612, 20.810, 7.882, 16.617, 13.740, 7.846, all P<0.05). The proportions of patients in the group ≤3 months of age required intensive care unit(ICU) hospitalization and mechanical ventilation were higher than those in the group > 3 months of age ( χ2=14.810, 21.436, all P<0.05). The mortality of the group ≤3 months of age was higher than that of the group >3 months of age ( χ2=12.016, P<0.05). Children ≤3 months of age had a higher WBC level [(27.83±27.70)×10 9/L vs.(23.34±15.28)×10 9/L, t=22.244, P<0.001], longer duration of spasmodic cough [(16.56±9.33) d vs.(15.06±6.16) d, t=10.145, P=0.002] and longer hospitalization time [(11.47±10.48) d vs.(9.48±4.80) d, t=20.050, P<0.001] than those >3 months of age.(3)Compared with the ordinary group, a higher proportion of children in the severe pertussis group were under 3 months old, and had not been vaccinated against pertussis vaccine ( χ2=14.803, 4.475, all P<0.05). The ratio of patients with dyspnea, an lymphocyte count/neutral cell(LC/NC) ratio <1, mixed infections, lung consolidation and pleural effusion in the severe pertussis group was higher than that in the ordinary group ( χ2=116.940, 43.625, 13.253, 106.370, 11.874, all P<0.05). The patients in the severe pertussis group had a higher WBC [(61.66±29.63)×10 9/L vs.(18.83±10.00)×10 9/L, t=112.580, P<0.001] and a lower LC (0.494±0.186 vs.0.676±0.132, t=13.752, P<0.001) than those in the ordinary group.(4)Compared with the single infection group, the proportions of children with fever, dyspnea, fine moist lung rales, an LC/NC ratio <1, and lung consolidation were higher in the mixed infection group ( χ2=8.909, 6.804, 7.563, 8.420, 12.458, all P<0.05). More children in the mixed infection group required ICU hospitalization and mechanical ventilation than those in the single infection group ( χ2=11.677, 7.397, all P<0.05). The mixed infection group had higher respiratory failure and death rates than the single infection group ( χ2=7.980, 4.267, all P<0.05). Compared with the single infection group, the mixed infection group had a higher WBC level [(27.73±24.13)×10 9/L vs.(21.25±14.65)×10 9/L, t=13.318, P<0.001], longer hospitalization time [(11.593±9.010) d vs.(8.339±4.047) d, t=17.283, P<0.001], and a smaller LC ratio (0.626±0.165 vs.0.684±0.132, t=7.997, P=0.005). (5) Logistic regression analysis showed that age ≤3 months, peak WBC and dyspnea were risk factors of severe pertussis. Conclusions:Hospitalized pertussis children are prone to pneumonia and pulmonary consolidation.Patients aged ≤3 months with a large WBC and dyspnea easily develop into severe pertussis.Monitoring blood routine is helpful for judging the severity of the disease.Mixed infections increase the incidence of complications and can impair the treatment effect.

Alcohol abuse leads to alcoholic liver disease and no effective therapy is currently available. Wuzhi Tablet (WZ), a preparation of extract fromthat is a traditional hepato-protective herb, exerted a significant protective effect against acetaminophen-induced liver injury in our recent studies, but whether WZ can alleviate alcohol-induced toxicity remains unclear. This study aimed to investigate the contribution of WZ to alcohol-induced liver injury by using chronic-binge and acute models of alcohol feeding. The activities of ALT and AST in serum were assessed as well as the level of GSH and the activity of SOD in the liver. The expression of CYP2E1 and proteins in the NRF2-ARE signaling pathway including NRF2, GCLC, GCLM, HO-1 were measured, and the effect of WZ on NRF2 transcriptional activity was determined. We found that both models resulted in liver steatosis accompanied by increased transaminase activities, but that liver injury was significantly attenuated by WZ. WZ administration also inhibited CYP2E1 expression induced by alcohol, and elevated the level of GSH and the activity of SOD in the liver. Moreover, the NRF2-ARE signaling pathway was activated by WZ and the target genes were all upregulated. Furthermore, WZ significantly activated NRF2 transcriptional activity. Collectively, our study demonstrates that WZ protected against alcohol-induced liver injury by reducing oxidative stress and improving antioxidant defense, possibly by activating the NRF2-ARE pathway.

BACKGROUND:
Changes in thyroid hormone levels are commonly recognized characters among the elderly, which were reported to potentially influence incident frailty. Therefore, we examined the cross-sectional associations of thyroid hormones (THs) with frailty as well as the five components characterizing frailty (fatigue, resistance, ambulation, number of illnesses, and loss of weight) among the oldest-old.
METHODS:
Four hundred and eighty-seven community-dwelling oldest-old from a local community in Haidian District, Beijing, participated in our recruitment campaign between April 2019 and May 2020. The primary outcomes were a definitive diagnosis of frailty according to the FRAIL scale (Fatigue, Resistance, Ambulation, Illnesses, Loss of weight) and a positive score for each frailty subdomain. Demographic information (age, sex, marital status, and educational status), comorbidities, and details on the participants' lifestyles were recorded. Serum THs including free triiodothyronin (fT3), triiodothyronine (T3), free thyroxine (fT4), and thyroxine (T4) and thyroid stimulating hormone (TSH) levels were also measured at the beginning of our study. Logistic regressions were conducted to screen for potential risk factors for frailty and its subdomains.
RESULTS:
Among the total 487 subjects at enrollment, 60 (12.23%) of them were diagnosed with subclinical hypothyroidism and 110 (22.59%) of the total population scored positive for frailty. Logistic regression analyses adjusted for all potential confounders, showed that frailty was significantly associated with the serum TSH concentration (odds ratio [OR]: 1.06), fT3 concentration (OR: 0.54), and subclinical hypothyroidism score (OR: 2.18). The association between fT4 and frailty was absent in our observational study. The fT3/fT4 ratio characterizing peripheral hormone conversion was also tested to be correlated with frailty.
CONCLUSION
Subclinical hypothyroidism, higher TSH level, lower fT3 level, and decreased fT3/fT4 ratio were all associated with frailty assessed by the FRAIL scale among the community-dwelling oldest-old, suggesting a relevant role of thyroid function in aging. Future longitudinal studies are warranted to determine the casual relationship between thyroid dysfunction and frailty in the oldest-old.
