Objective To explore the application effect of enhanced recovery after surgery(ERAS)strategy in secondary cesarean delivery.Methods A total of 90 puerperae who underwent elective secondary cesarean delivery in our hospital were enrolled and randomly divided into the observation group and the control group,with 45 cases in each group.Puerperae in the observation group adopted ERAS management,and puerperae in the control group adopted routine management.The postoperative recovery indicators,clinical outcome indicators,scores of self-rating anxiety scale(SAS),self-rating depression scale(SDS),and Kolcaba general comfort questionnaire(GCQ)of puerperae between the two groups were compared.Results The obstetric quality of recovery-11(ObsQoR-11)score 24 hours after surgery of puerperae in the observation group was higher than that in the control group(P<0.05),the recovery time of postoperative bowel sounds and first defecating time were shorter than those in the control group(P<0.05),the height of uterine fundus 72 hours after surgery was lower than that in the control group(P<0.05),the incidences of moderate to severe pain at rest and during cough were lower than those in the control group(P<0.05).There was no statistically significant difference in the incidence of neonatal transfer to the intensive care unit or the incidence of jaundice between the two groups(P>0.05);while the incidences of intraoperative hypotension,nausea and vomiting,chills,and postoperative abdominal distension,nausea and vomiting of puerperae in the observation group were lower than those in the control group(P<0.05),postoperative vaginal bleeding volume within 24 hours was less than that in the control group(P<0.05).After intervention,the SAS,SDS and GCQ scores of puerperae in both groups were lower than those before intervention(P<0.05),and the SAS and SDS scores of puerperae in the observation group were lower than those in the control group(P<0.05),the GCQ score was higher than that in the control group(P<0.05).Conclusion ERAS strategy used for secondary cesarean delivery can improve clinical outcomes and psychological state of puerperae,increase comfort level,and promote postoperative recovery.

Objective To explore the application effect of dexmedetomidine combined with ropivacaine for quadratus lumborum block at the lateral supra-arcuate ligament(QLB-LSAL) in open hepatocellular carcinoma resection.Methods A prospective study was conducted in 60 patients who underwent elective open hepatocellular carcinoma resection at Jining First People's Hospital. The patients were randomly divided into the compound group and the control group,with 30 cases in each group. Patients in the compound group received QLB-LSAL combined general anesthesia,and patients in the control group received simple general anesthesia. All patients underwent patient controlled intravenous analgesia (PCIA)postoperatively. The mean arterial pressure (MAP),heart rate (HR) and visual analogue scale (VAS) scores during rest and coughing at different time points were observed and compared between the two groups. The number of postoperative PCIA compressions,the dosage of sufentanil,the first postoperative exhaust time,the first postoperative ambulation time,the hospital stay and the occurrence of adverse reactions of the two groups were recorded. Results In the compound group,the HR and MAP were significantly lower than those of the control group at the time of skin incision (T2) and at the end of surgery (T3);the VAS scores during rest and coughing were significantly lower than those of the control group at the time of exiting the anesthesia recovery room and 6 hours and 12 hours after surgery;and the PCIA compression times were significantly less than those of the control group;the dosage of sufentanil was significantly lower than that in the control group 0 to 24 hours after surgery,and the dosage of sufentanil was higher than that in the control group 25 to 48 hours after surgery;the first postoperative ambulation time and the first postoperative exhaust time were significantly earlier than those in the control group;and the above differences were statistically significant(P<0.05). There was no significant difference in the HR or MAP at 5 minutes into the operating room (T0) and 5 minutes before skin incision (T1),VAS scores during rest and coughing 24 hours and 48 hours after surgery,hospital stay and incidence of adverse reactions between the two groups (P>0.05).Conclusion For patients with open hepatocellular carcinoma resection,dexmedetomidine combined with ropivazine for QLB-LSAL can provide more ideal postoperative analgesia,reduce perioperative opioid consumption,and have less impact on circulatory system,which is conducive to rapid postoperative recovery.

During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.

Objectives: To investigated the safety and efficacy of treating patients with acute non-ST-segment elevation myocardial infarction (NSTEMI) and elevated levels of N-terminal pro-hormone B-type natriuretic peptide (NT-proBNP) with levosimendan within 24 hours of first medical contact (FMC). Methods: This multicenter, open-label, block-randomized controlled trial (NCT03189901) investigated the safety and efficacy of levosimendan as an early management strategy of acute heart failure (EMS-AHF) for patients with NSTEMI and high NT-proBNP levels. This study included 255 patients with NSTEMI and elevated NT-proBNP levels, including 142 males and 113 females with a median age of 65 (58-70) years, and were admitted in the emergency or outpatient departments at 14 medical centers in China between October 2017 and October 2021. The patients were randomly divided into a levosimendan group (n=129) and a control group (n=126). The primary outcome measure was NT-proBNP levels on day 3 of treatment and changes in the NT-proBNP levels from baseline on day 5 after randomization. The secondary outcome measures included the proportion of patients with more than 30% reduction in NT-proBNP levels from baseline, major adverse cardiovascular events (MACE) during hospitalization and at 6 months after hospitalization, safety during the treatment, and health economics indices. The measurement data parameters between groups were compared using the t-test or the non-parametric test. The count data parameters were compared between groups using the χ² test. Results: On day 3, the NT-proBNP levels in the levosimendan group were lower than the control group but were statistically insignificant [866 (455, 1 960) vs. 1 118 (459, 2 417) ng/L, Z=-1.25,P=0.21]. However, on day 5, changes in the NT-proBNP levels from baseline in the levosimendan group were significantly higher than the control group [67.6% (33.8%,82.5%)vs.54.8% (7.3%,77.9%), Z=-2.14, P=0.03]. There were no significant differences in the proportion of patients with more than 30% reduction in the NT-proBNP levels on day 5 between the levosimendan and the control groups [77.5% (100/129) vs. 69.0% (87/126), χ²=2.34, P=0.13]. Furthermore, incidences of MACE did not show any significant differences between the two groups during hospitalization [4.7% (6/129) vs. 7.1% (9/126), χ²=0.72, P=0.40] and at 6 months [14.7% (19/129) vs. 12.7% (16/126), χ²=0.22, P=0.64]. Four cardiac deaths were reported in the control group during hospitalization [0 (0/129) vs. 3.2% (4/126), P=0.06]. However, 6-month survival rates were comparable between the two groups (log-rank test, P=0.18). Moreover, adverse events or serious adverse events such as shock, ventricular fibrillation, and ventricular tachycardia were not reported in both the groups during levosimendan treatment (days 0-1). The total cost of hospitalization [34 591.00(15 527.46,59 324.80) vs. 37 144.65(16 066.90,63 919.00)yuan, Z=-0.26, P=0.80] and the total length of hospitalization [9 (8, 12) vs. 10 (7, 13) days, Z=0.72, P=0.72] were lower for patients in the levosimendan group compared to those in the control group, but did not show statistically significant differences. Conclusions: Early administration of levosimendan reduced NT-proBNP levels in NSTEMI patients with elevated NT-proBNP and did not increase the total cost and length of hospitalization, but did not significantly improve MACE during hospitalization or at 6 months.

Objective: To investigate the frequency characteristics and the pathological characteristics of the horizontal crista ampullaris in patients with Meniere's disease,and to analyse its structural basis. Methods: Between March, 2019 and November, 2019, seventy-two patients diagnosed as Meniere's disease (27 males and 45 females, aged from 13 to 74 years, with a course of disease ranging from 4 months to 32 years)in Shandong Provincial ENT Hospital were included.Caloric test, sinusoidal harmonic acceleration test (SHA), video-head impulse test (v-HIT), Gadolinium-enhanced inner-ear 3D-FLAIR MRI and pure tone audiometry were conducted in the patients. The function of the horizontal semicircular canal in these patients were analysed as well as its relationship with the degree of endolymphatic hydrops,clinical stage and duration. Light microscopy and transmission electron microscopy were used to observe the ultrastructure of horizontal semicircular canal crista ampullaris from six patients with refractory Meniere's disease who underwent labyrinthectomy. The number of type Ⅰ and type Ⅱ vestibular hair cells, the common pathophysiological changes of horizontal semicircular canal crista ampullaris were investigated in these patients. Statistical analysis was performed using SPSS 19.0. Results: With the increase of detection frequency, the abnormal rate decreased gradually. The abnormal rate of caloric test was 69.4% (50/72), SHA 51.4% (37/72), V-HIT 36.1% (26/72), comparation of the positive rate among the three tests showed statistically significant differences(P<0.05).Neither caloric test nor SHA had correlation with the degree of hydrops(P>0.05), but v-HIT(r=0.434,P<0.01).There was correlation with clinical stage to SHA and v-HIT(r=0.338,0.462,P<0.01), except caloric test(P>0.05).No significant relation was found with caloric test, SHA, v-HIT and course of disease(P>0.05).Morphological observation found abnormal monolayer epithelialization of the horizontal semicircular canal crista ampullaris significantly decreased number of type Ⅱ hair cells compared with type Ⅰhair cells. Hair cells showed perinuclear vacuolization, cytoplasmic vacuoles, mitochondrial electron density increasement and loss of stereocilia. Conclusions: The horizontal semicircular canal damage in the patients with Meniere's disease has a frequency-dependent characteristic, mainly occurres in low frequency area. With progress of the disease, the high frequency area of ampulla will be impaired gradually, and it is related to the degree of endolymphatic hydrops and hearing level. Hair cell injury would be observed,the frequency characteristics may be more associated with the disorder of type Ⅱ hair cells.

BACKGROUNDAwake fiberoptic intubation (AFOI) is usually performed in the management of the predicted difficult airway. The aim of this study was to evaluate the feasibility of dexmedetomidine with midazolam (DM) and sufentanil with midazolam (SM) for sedation for awake fiberoptic nasotracheal intubation.

METHODSFifty patients with limited mouth opening scheduled for AFOI were randomly assigned to two groups (n = 25 per group) by a computer-generated randomization schedule. All subjects received midazolam 0.02 mg/kg as premedication and airway topical anesthesia with a modified "spray-as-you-go" technique. Group DM received dexmedetomidine at a loading dose of 0.5 μg/kg over 10 min followed by a continuous infusion of 0.25 μg·kg-1·h-1, whereas Group SM received sufentanil at a loading dose of 0.2 μg/kg over 10 min followed by a continuous infusion of 0.1 μg·kg-1·h-1. As necessary, since the end of the administration of the loading dose of the study drug, an additional dose of midazolam 0.5 mg at 2-min intervals was given to achieve a modified Observers' Assessment of Alertness/Sedation of 2-3. The quality of intubation conditions and adverse events were observed.

RESULTSThe scores of ease of the AFOI procedure, patient's reaction during AFOI, coughing severity, tolerance after intubation, recall of the procedure and discomfort during the procedure were comparable in both groups (z = 0.572, 0.664, 1.297, 0.467, 0.895, and 0.188, respectively, P > 0.05). Hypoxic episodes similarly occurred in the two groups, but the first partial pressure of end-tidal CO2after intubation was higher in Group SM than that in Group DM (45.2 ± 4.2 mmHg vs. 42.2 ± 4.3 mmHg, t = 2.495, P < 0.05).

CONCLUSIONSBoth dexmedetomidine and sufentanil are effective as an adjuvant for AFOI under airway topical anesthesia combined with midazolam sedation, but respiratory depression is still a potential risk in the sufentanil regimen.

OBJECTIVETo investigate the correlation between expression of A-kinase anchoring protein 95 (AKAP95) and protein expression of cyclin E1 and cyclin D1 in lung cancer tissue.

METHODSFifty-one cases of lung cancer were included in the study. The protein expression of AKAP95, cyclin E1, and cyclin D1 were measured by immunohistochemistry.

RESULTSThe protein expression of cyclin E1 in lung cancer tissues was significantly higher than that in para-cancerous tissues (positive rate: 75.56%vs 20%, P < 0.01); its expression showed no relationship with histopathological type, lymph node metastasis, and cellular differentiation (P > 0.05). The protein expression of cyclin D1 in lung cancer tissues was higher than that in para-cancerous tissues (positive rate: 69.39% vs 14.29%); its expression showed a significant relationship with histopathological type (P < 0.05). The expression of AKAP95 was correlated with the protein expression of cyclin E1 and cyclin D1 in lung cancer tissues (P < 0.01).

CONCLUSIONCyclin E1 and cyclin D1 are highly expressed in lung cancer tissue, suggesting that they play an important role in the development and progression of lung cancer. The protein expression of cyclin E1 has no relationship with cellular differentiation, lymph node metastasis, and histopathological type of lung cancer, and the protein expression of cyclin D1 has a significant relationship with histopathological type. The expression of AKAP95 is correlated with the protein expression of cyclin E1 and cyclin D1 in lung cancer tissue.

The donkey leukocyte-attenuated vaccine of equine infectious anemia virus (EIAV) was the first lentiviral vaccine that induced solid protection from the infection of virulent strains. To elucidate the mechanism of increased immunogenicity and attenuated virulence of the vaccine, the proviral genomic DNA of an EIAV vaccine strain, EIAV(DLV121) was analyzed and compared with the genome of a parental virulent strain EIAV(DV117). Full length viral genomic DNAs were amplified as two segments by LA-PCR and were cloned. Because of the genomic diversity of retroviral quasispecies, 10 full-length sequences of EIAV(DLV121) and 4 full-length sequences of EIAV(DV117) from randomly picked clones were analyzed. Results showed that the average length of the complete nucleotide sequence of EIAV(DLV121) was 8,236bp and EIAV(DV117) was 8,249bp, with the inter-strain diversity of 2.8%. As for individual genes between the vaccine and virulent strains, the differences in nucleotide sequence of S2, LTR and env were significantly higher than the other genes with the diversity of 4.1%, 3.7% and 3.1%, respectively. Considerable variations in deduced amino acid sequences were found in S2, S3 and env. The diversities were 10.4%, 5.6% and 4.8%, respectively. Furthermore, the LTR of EIAV(DLV121) consisted of at least 5 subtypes grouped by their nucleotide sequences. There were two additional N-linked glycosylation sites in the deduced amino acid sequence of EIAV(DV117) gp90 than that of EIAV(DLV121). Among glycosylation sites in the gp90 of virulent strain, 3 were found unique only in EIAV(DV117), of which 2 were located in the principle neutralizing domain (PND). In addition, there was one EIAV(DLV121) -specific glycosylation site, which was positioned in the PND, too. Taken together, it is clear that greatly increased genomic diversity exists in the EIAV vaccine strain, which provides important information for the further study on biological characters of the Chinese EIAV attenuated vaccine.
