Objective To investigate the factors affecting the occurrence of new postoperative cardiac complications in patients undergoing esophageal cancer surgery with concomitant coronary heart disease. Methods Clinical data of patients who underwent esophageal cancer surgery with coronary heart disease at the Affiliated Huai'an No.1 People's Hospital of Nanjing Medical University from December 2019 to June 2023 were collected. Patients were divided into two groups based on whether they experienced postoperative cardiac complications. Using the occurrence of cardiac complications as the dependent variable, a multivariate logistic regression model was established to identify related influencing factors. Results A total of 223 patients were included, comprising 148 males and 75 females, with an average age of (71.78±6.31) years (range 53-88 years). Seventy-one (31.84%) patients experienced at least one new cardiac complication postoperatively, including 2 acute coronary syndrome, 13 heart failure, and 59 new-onset postoperative arrhythmias. Univariate analysis showed that age, systemic immune-inflammation index, pulmonary infection, need for invasive mechanical ventilation due to respiratory failure, acute respiratory distress syndrome (ARDS), acute delirium, pleural effusion requiring drainage, and acute renal failure were risk factors for postoperative new-onset cardiac complications (all P<0.05). Multivariate logistic regression analysis identified age, postoperative length of hospital stay, ARDS, and systemic immune-inflammation index as independent risk factors for new cardiac complications in esophageal cancer patients with coronary heart disease. Conclusion Strengthening perioperative management of esophageal cancer patients, ranging from preoperative evaluation to postoperative complication treatment, is crucial. Particular attention should be paid to age, ARDS, and other indicators to improve postoperative prognoses in patients with coronary heart disease complicated by esophageal cancer.

Acute and critical illnesses pose a serious threat to people's lives and health,causing great difficulties for doctors to rescue them.As an important part of traditional Chinese medicine(TCM)clinical medicine,emergency medicine of TCM has formed its own unique and complete theoretical system and accumulated rich clinical experience in the long-term struggle against diseases by the unremitting efforts of generations of doctors.As a well-known contemporary expert in TCM clinical emergency treatment,Professor Liu Qingquan has been deeply involved in the front line of clinical work,and creatively proposed the theory of three states and three principles differentiation,providing a rapid and effective core idea for the treatment of contemporary acute and critical patients with TCM.

Objective To evaluate the noise hazard level of a coal mining enterprise, and identify high-risk operation types and people, and to provide a basis for preventing and controlling the health damage caused by noise. Methods A large coal mining enterprise in Shaanxi Province was selected as the research object. The noise monitoring data of the coal mine over the years was used to calculate the noise exposure matrix of each post in the enterprise, and the classification of occupational hazards at workplaces (GBZ/T 229.4-2012) was used to assess the occupational health risk levels. Results Among the 22 noise-exposed positions in the enterprise, the 8-hour working day equivalent sound level in positions of shearer driver, horseshoe driver, crusher driver, shuttle driver, relaxation screen driver, and grading screen driver were all higher than the occupational exposure limit of noise. In 2021, the noise exposure levels of shearer drivers, crusher drivers, and coal-selecting workers were all higher than 90 dB (A), and the occupational hazard level was moderate hazard level. In addition, the noise exposure levels of most other jobs also exceeded the occupational exposure limit. Conclusion The noise hazards in the coal mine industry are mainly concentrated in the posts of the coal mining system, tunneling system, and screening workshop. Among them, the shearer driver, the crusher driver, and the coal preparation workers have higher noise exposure levels. It is recommended to take corresponding noise reduction measures and strengthen the protection level to reduce the noise exposure risk of workers.

As a new hypoglycemic drug,Dapagliflozin has attracted much attention because of its unique hypoglycemic mechanism. It has been used in many studies on type 2 diabetes mellitus,but the application of type 1 diabetes mellitus(T1DM)in the eastern population is rare. This article uses Dapagliflozin through a case of obese T1DM to provide new ideas for the treatment of T1DM.

Objective:To develop a risk prediction lineogram of neooperative atrial fibrillation in patients with esophageal cancer.Methods:The clinical data of 1 509 patients undergoing esophageal cancer surgery admitted to the department of esophageal surgery of our hospital from December 2019 to April 2022 were gathered, and they were divided into two layers according to whether they had new atrial fibrillation after surgery. In each layer, they were randomly divided into training set and test set in a ratio of 7∶3. In the training population, the multi-factor logistic regression method was used to establish the prediction model, and the line graph of the prediction model was drawn. The ROC curve and calibration curve were drawn to assess the differentiation ability and calibration ability of the prediction model. The test set population is used to validate the prediction model. Results:A total of 1 509 patients with esophageal cancer were included in the study, and the incidence of new atrial fibrillation after surgery was 247 patients(16.4%). A total of 1 039 patients(68.9%) were enrolled in the training set. The multivariate logistic regression model indicated that age, gender, BMI, pulmonary infection, the use of invasive ventilator, and the need for additional drainage of fluid accumulation were the influencing factors for new postoperative atrial fibrillation. The AUC of the training set prediction model under ROC curve was 0.775(95% CI: 0.737-0.812, P<0.001), indicating that the model has high predictive discrimination ability. Calibration curve and Hosmer- Lemeshow test results P=0.796, indicating that the model has good consistency of prediction ability. There were 470 subjects(31.1%) in the test set. The results showed that the AUC of the prediction model under the ROC curve was 0.773(95% CI: 0.719-0.826, P<0.001), indicating that the prediction model still has a high discriminative ability in the test set population. Conclusion:Patients with age, gender, BMI, pulmonary infection, the use of invasive ventilator, and the need for additional drainage of effusion are at higher risk of new atrial fibrillation after surgery. The timely prediction, prevention and management of POAF are crucial to improve the prognostic quality of postoperative patients with esophageal cancer by constructing clinical prediction models.

【Objective】 To explore the technical methods and clinical efficacy of transvaginal or transrectal repair in the treatment of iatrogenic bladder fistula. 【Methods】 The clinical data of 7 cases of iatrogenic bladder fistula patients treated during 2016 and 2019 were retrospectively analyzed, including 6 cases of vesicovaginal fistula (VVF) and 1 case of vesicorectal fistula (VRF). The operation was conducted 3 to 10 months after the diagnosis of urinary fistula, and the vagina or rectum was fully cleaned before operation. Modified Latzko technique was employed to separate the gap between the bladder wall and vaginal or rectal wall along the fistula, the fistula scar was sharply removed, and the fistula, bladder wall, vaginal or intestinal wall, and vaginal or intestinal mucosa were sutured in layers. The urinary catheter was indwelled for 4 weeks. 【Results】 All 7 cases were successfully repaired at one procedure. No urine leakage was found after the urinary catheter was removed. There was no recurrence after 6 to 12 months of follow-up. 【Conclusion】 Selective application of the modified Latzko technique to repair iatrogenic urinary fistula through the natural lumen is an advantageous treatment scheme, which simplifies the operation and reduces trauma.

Objective To evaluate the diagnostic accuracy of CMS50F for screening in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS). Methods Sixty-four volunteers with suspected OSAHS underwent simultaneous noc?turnal polysomnography (PSG), micromovement sensitive mattress sleep monitoring system(MSMSMS)and CMS50F. The ap?nea-hypopnea index (AHI) detected by PSG and MSMSMS was used as the diagnostic standard for OSAHS. The reliability of CMS50F for monitoring sleep was assessed. Results There was no statistic difference in CMS50F-ODI3 and PSG-AHI be?tween normal, mild and moderate OSAHS groups(P>0.05). The CMS50F-ODI3 was smaller than the PSG-AHI in severe OSAHS patients(P < 0.05). There was a positive correlation between CMS50F-ODI3 and PSG-AHI(r=0.855, P < 0.05). PSG-AHI≥5 events per hour was used as the threshold value to diagnose OSAHS, the sensitivity and specificity of CMS50F were 94.5%and 88.9%. There were no significant differences in CMS50F-ODI3 and MSMSMS-AHI between normal, mild and moderate OSAHS patients(P>0.05). The value of CMS50F-ODI3 was smaller than MSMSMS-AHI in severe OSAHS patients (P < 0.05). There was also a significant correlation between CMS50F- ODI3 and MSMSMS-AHI (r=0.867,P <0.05). MSMSMS-AHI≥5 events per hour was used as the threshold value to diagnose OSAHS, the sensitivity and specificity of CMS50F were 94.5%and 88.9%. Conclusion CMS50F can be used as a portable and reliable device for screening of pa?tients suspected OSAHS.

Objective To compare the clinical effects of proximal femoral nail antirotation (PFNA) and proximal femoral nail antirotation-Ⅱ (PFNA-Ⅱ) in the internal fixation of femoral intertrochanteric fracture.Methods A retrospective study was conducted of the 54 patients with femoral intertrochanteric fracture who had been treated at our department from May 2009 through July 2014.During May 2009 and November 2011,27 of them were treated with PFNA;during December 2011 and July 2014,the other 27 of them were treated with PFNA-Ⅱ.The 2 groups were compared in terms of operation time,intraoperative blood loss volume,hidden blood loss volume,intraoperative and postoperative complications,fracture healing time and Harris hip score at the last follow-up.Results In the PFNA group,27 patients were followed up for an average time of 22.6 ± 4.8 months.In the PFNA-Ⅱ group,27 patients were followed up for an average time of 19.5 ± 4.6 months.The PFNA group had significantly more intraoperative blood loss volume (130.1 ± 74.3 mL),and significantly higher rates of intraoperative lateral wall fracture of the proximal femur (18.5％,5/27),postoperative lateral thigh soft tissue irritation (22.2％,6/27) and postoperative thigh pain (22.2％,6/27) than the PFNA-Ⅱ group [46.3 ± 23.1 mL,0,3.7％ (1/27),3.7％ (1/27),respectively] (P ＜ 0.05).There were no significant differences between the 2 groups in operation time,hidden blood loss,postoperative complications of internal diseases,fracture healing time,or Harris hip score of last follow-up (P ＞ 0.05).Conclusion Compared with PFNA,PFNA-Ⅱ may lead to a smaller volume of intraoperative blood loss and a lower incidence of complications related to internal fixation.

Objective To investigate the neuroprotective effect of cattle encephalon glycoside and ignotin injection on the rat model of traumatic brain injury (TBI).Methods Three hundred and six SD rats were randomly divided into sham group,TBI group,high dose group,middle dose group and low dose group according to the random number table.Rats received 1.8,0.6 and 0.2 ml/kg of cattle encephalon glycoside and ignotin injection for 28 days in high,middle and low dose groups,respectively.TBI was induced by the modified Feeney' s weight-drop method.Rat mortality,neurological function score and learning and memory ability were recorded.Brain morphological changes were evaluated with 7.0 T small animal nuclear magnetic resonance and HE staining.Evans blue was applied to assess blood brain barrier (BBB) permeability and hydrocephalus was evaluated by the brain water content.Results Mortality in high dose group decreased significantly compared to that in TBI group (22.40％ vs.28.14％,P ＜ 0.05).Defects in neurological function and learning and memory induced by TBI were significantly mitigated in middle and high dose groups (P ＜ 0.05).Pathological damage and contralateral hippocampal atrophy in middle and high dose groups were reduced significantly compared to TBI group (P ＜ 0.05).Hippocampus neuroapoptosis in middle and high dose groups was significantly improved compared to TBI group (P ＜ 0.05).BBB damage was less severe in middle and high dose groups than in TBI group (P ＜ 0.05).The treatment was preventive against secondary hydrocephalus.Conclusion Middle or high dose cattle encephalon glycoside and ignotin injection over a 28-day period has significant neuroprotective effect on the TBI rats.
