BACKGROUND: Enhanced recovery after surgery (ERAS) protocols are a series of perioperative care to optimize preoperative preparation, prevent postoperative complications, minimize stress, and speed up recovery. This study aimed to assess the impact of ERAS protocols for functional endoscopic sinus surgery (FESS) in patients with chronic rhinosinusitis with nasal polyps (CRSwNP). METHODS: One hundred and two patients with CRSwNP undergoing FESS were randomly divided into the ERAS group and the control group. The outcomes of the Self-Rating Anxiety Scale (SAS), Visual Analogue Scale (VAS), Medical Outcomes Study Sleep Scale (MOS-SS) and Kolcaba Comfort Scale Questionnaire (GCQ) were determined in both groups. The serum levels of C-reactive protein (CRP) were compared preoperatively and 24 hours postoperatively. RESULTS: The ERAS group had a significantly better SAS scores than did the control group (28 [24, 35] vs. 43 [42, 47], Z = 5.968, P < 0.001). The rhinalgia and headache scores at 2, 24 and 48 hours postoperatively were lower in the ERAS group than that in the control group (all P < 0.001). The outcomes of the MOS-SS (43 [42, 39] vs. 28 [22, 35], Z = 7.071, P < 0.001) and GCQ (76 [68, 87] vs. 64 [50, 75], Z = 4.806, P < 0.001) were significantly different between the two groups. No significant difference was found in the preoperative CRP levels between the two groups (1.3 [0.6, 2.8] vs. 0.5 [0.5, 1.2], Z = 3.049, P > 0.05); However, the CRP level in 24 hours postoperatively was significantly lower in the ERAS group than that in the control group (2.5 [1.4, 3.9] vs. 6.6 [3.8, 9.0], Z = 5.027, P < 0.001). The incidence rates of complications, such as nausea/emesis (χ = 0.343, P > 0.05), hemorrhage, aspiration and tumble, were not increased in the ERAS group compared with those in the control group. The ERAS group had a significantly shorter length of hospital stay (5 [4, 5] days vs. 8 [8,9] days, Z = 8.939, P < 0.001) and hospitalization expenses ($ 2670 [2375, 2740] vs. $3129 [3116, 3456], Z = 8.514, P < 0.001). CONCLUSIONS: ERAS protocols might optimize FESS for patients with CRSwNP by reducing psychological and physical stress, shortening the length of hospital stay and lowering hospitalization expenses without increasing postoperative complications.

In the present study, we investigated anti-inflammatory effect of Cardamine komarovii flower (CKF) on lipopolysaccharide (LPS)-induced acute lung injury (ALI). We determined the effect of CKF methanolic extracts on LPS-induced pro-inflammatory mediators NO and prostaglandin E2 (PGE2), production of pro-inflammatory cytokines (IL-1β, TNF-α, and IL-6), and related protein expression levels of MyD88/TRIF signaling pathways in peritoneal macrophages (PMs). Nuclear translocation of NF-κB-p65 was analyzed by immunofluorescence. For the in vivo experiments, an ALI model was established to detect the number of inflammatory cells and inflammatory factors (IL-1β, TNF-α, and IL-6) in bronchoalveolar lavage fluid (BALF) of mice. The pathological damage in lung tissues was evaluated through H&E staining. Our results showed that CKF can decrease the production of inflammatory mediators, such as NO and PGE2, by inhibiting their synthesis-related enzymes iNOS and COX-2 in LPS-induced PMs. In addition, CKF can downregulate the mRNA levels of IL-1β, TNF-α, and IL-6 to inhibit the production of inflammatory factors. Mechanism studies indicated that CKF possesses a fine anti-inflammatory effect by regulating MyD88/TRIF dependent signaling pathways. Immunocytochemistry staining showed that the CKF extract attenuates the LPS-induced translocation of NF-kB p65 subunit in the nucleus from the cytoplasm. In vivo experiments revealed that the number of inflammatory cells and IL-1β in BALF of mice decrease after CKF treatment. Histopathological observation of lung tissues showed that CKF can remarkably improve alveolar clearance and infiltration of interstitial and alveolar cells after LPS stimulation. In conclusion, our results suggest that CKF inhibits LPS-induced inflammatory response by inhibiting the MyD88/TRIF signaling pathways, thereby protecting mice from LPS-induced ALI.

Saponin frsom Cortex Albiziae (SCA) are extensively used in the clinical treatment of tumor and depression. However, SCA may cause several adverse effects, including reproductive toxicity. The present study was designed to assess the mechanism by which SCA cause reproductive toxicity in female mice. The general reproductive toxicity testing was accomplished in female Kunming mice. The animals were divided into four groups: three groups that were treated by oral gavage with 135, 270, and 540 mg·kg(-1)·d(-1) of SCA prepared in physiological saline, respectively, and one vehicle control group that was treated with physiological saline only. The gestational toxicity tests were conducted at 540 mg·kg(-1)·d(-1). The general reproductive toxicity results showed that the pregnancy rate of the SCA-treated group decreased with the pregnancy rate being decreased by 70% at 540 mg·kg(-1)·d(-1). SCA elicited maternal toxicity in the ovary and the uterus, but no fetal toxicity or teratogenicity was observed. The rates of implantation in the early, middle, and late pregnancy were all decreased, with stillbirths and maternal deaths being observed. Histopathological changes showed that SCA adversely affected the ovary and the uterus. In conclusion, SCA-induced reproductive toxicity in female mice is most likely caused by its damage to the ovary and the uterus.

INTRODUCTION: We investigated the epidemiological features of the 2007 dengue outbreak to determine the factors that could have triggered it two years after the previous large outbreak in 2005.

METHODS: All laboratory-confirmed cases of dengue reported during the year, as well as entomological and virological data, were analysed.

RESULTS: A total of 8826 cases including 24 deaths were reported in 2007, giving an incidence of 192.3 cases per 100 000 residents and a case-fatality rate of 0.27%. The median age of the cases was 37 years (interquartile range 25 to 50), with an age range from two days to 101 years, which was higher than the median age of 31 years (interquartile range 20 to 42), with a range from four days to 98 years, in 2005. The overall Aedes premises index in 2007 was 0.68%, lower than the 1.15% observed in 2005. The predominant dengue serotype in 2007 was dengue virus DENV-2 which re-emerged with a clade replacement in early 2007, and overtook the predominant serotype (DENV-1) of 2005. Seroprevalence studies conducted in the three largest outbreak clusters revealed that 73.2% of residents with recent infection were asymptomatic.

DISCUSSION: With the exception of an increase in the median age of the cases, and a change in the predominant dengue serotype, the epidemiological features of the 2007 epidemic were largely similar to those of 2005. Singapore remains vulnerable to major outbreaks of dengue, despite sustained vector control measures to maintain a consistently low Aedes premises index.
