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.

This article aims to explore the effect and mechanism of Liujunzi Pills on the intestinal microbiota of rats with spleen Qi deficiency syndrome. The raw Rhei Radix et Rhizoma water extract(1 g·mL~(-1)) was used to prepare spleen Qi deficiency rat models. A total of 44 SD male rats were randomly divided into a control group, a model group, Liujunzi Pills groups at high(3.24 g·kg~(-1)), medium(1.62 g·kg~(-1)), low(0.81 g·kg~(-1)) doses, and Shenling Baizhu San(2.50 g·kg~(-1)) group. The drug effect was evaluated by observing the following aspects: spleen index, fecal water content, body weight, and intestinal propulsion index. Gut microbiota analysis and 16S rRNA gene sequencing were conducted on feces. Enzyme-linked immunosorbent assay(ELISA) and UV spectrophotometry were used to detect interleukin-1β(IL-1β) and adenosine triphosphate(ATP) levels in small intestine tissues. Hematoxylin-eosin staining and transmission electron microscopy were employed to observe changes in intestinal pathology and microstructure. The results show that, compared with the control group, fecal moisture content is significantly increased while spleen index, body weight, and intestinal propulsion index are significantly reduced in rats of the model group, indicating the successful establishment of the model. The above symptoms can be improved by both Shenling Baizhu San and Liujunzi Pills. Compared with the control group, in the model group, the gut microbiota abundance is changed with an unbalanced development: the abundance of beneficial bacteria within the Bacteroidetes phylum is reduced, accompanied by a significantly decreased Shannon index, and reduced signal levels of nicotinamide adenine dinucleotide phosphate(NADPH)-related enzymes relevant to mitochondria. However, Liujunzi Pills and Shenling Baizhu San can significantly improve the Bacteroidetes phylum abundance in gut microbiota, microbial diversity, and NADPH activity in the model group. Additionally, compared with the control group, the ATP level is decreased and the IL-1β level is increased in small intestinal tissues of the model group, with shorter small intestinal epithelial villi and decreased mitochondrial number. The above symptoms can be improved by Liujunzi Pills and Shenling Baizhu San. In conclusion, Liujunzi Pills can treat spleen Qi deficiency syndrome by enhancing mitochondrial function to regulate gut microbiota balance and diversity.

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.

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 application effect of different levels of quantitative walking management in diabetic nephropathy patients.Methods:A total of 216 diabetic nephropathy patients who regularly visited Nephrology Outpatient Department of the First Affiliated Hospital of Xinjiang Medical University from September 2020 to February 2021 were selected as research objects by the convenient sampling method. According to the random number table method, they were divided into low walking volume group (5 000-7 499 steps/d) , medium walking volume group (7 500-9 999 steps/d ) and high walking volume group (≥10 000 steps/d) , with 72 cases in each group. They were given walking exercise for 8 weeks. Fasting blood glucose, glycosylated hemoglobin, 24-hour urinary protein, serum creatinine, glomerular filtration rate and Multidimensional Fatigue Inventory-20 Scale (MFI-20) scores were compared among all groups.Results:A total of 209 patients completed the study, including 71, 70 and 68 patients in the low, medium and high step groups, respectively. The average daily walking volume in the three groups was (6 973.52±536.47) , (8 461.35±721.38) and (11 134.28±632.69) steps per day, respectively. After intervention, fasting blood glucose, glycosylated hemoglobin, 24-hour urine protein, serum creatinine and MFI-20 scores in the three groups decreased compared with before intervention, and glomerular filtration rate increased compared with before intervention. And there were statistically significant differences in all indicators in the medium walking volume group ( P<0.05) . Fasting blood glucose, glycosylated hemoglobin, glomerular filtration rate and MFI-20 scores in the high walking volume group were significantly different from those before intervention ( P<0.05) . There was no statistically significant difference between the indexes of the low walking volume group and those before intervention ( P>0.05) . After intervention, fasting blood glucose, glycosylated hemoglobin, MFI-20 score were the lowest in the high walking volume group, the glomerular filtration rate was the highest in the medium walking volume group, and the 24-hour urinary protein quantity and serum creatinine were the lowest in the medium walking volume group. There were statistically significant differences among the three groups in variance analysis and pair comparison of each index ( P<0.05) . Conclusions:Medium and high walking volume exercise can effectively improve blood glucose level, renal function and fatigue state in diabetic nephropathy patients, and moderate walking volume has better effect on albuminuria and renal function.

【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 investigate the clinical effect of posterior fossa decompression combined with dural reconstruction in the treatment of Chiari malformation-Ⅰ(CM-Ⅰ) complicated with syringomyelia (SM).Methods:The clinical data of 50 patients with CM-Ⅰ complicated with SM who were treated in Yan′an University Xianyang Hospital from June 2019 to January 2021 were analyzed. They were divided into the study group (27 cases) and the control group (23 cases) according to the surgical methods. The former received posterior fossa decompression combined with dural reconstruction, while the latter received posterior fossa decompression alone. The clinical symptom improvement, neurological function, cerebrospinal fluid dynamics and syringomyelia changes were compared between the two groups before and after the surgery, and postoperative complications were compared.Results:The overall clinical symptom improvement rate between the two groups had no significant difference ( P> 0.05). After the surgery, the scores of pain, sensory disturbance, dyskinesia and ataxia in the study group were higher than those in the control group: (4.56 ± 0.35) points vs. (4.28 ± 0.43) points, (3.61 ± 0.82) points vs. (3.15 ± 0.73) points, (3.81 ± 0.44) points vs. (3.59 ± 0.50) points, (4.43 ± 0.41) points vs. (4.09 ± 0.53) points, there were statistical significant ( P<0.05). After the surgery, the cerebrospinal fluid stroke volume (SV) and mean flow (MF) in the study group were higher than those in the control group: (0.05 ± 0.02) ml vs. (0.04 ± 0.01) ml, (0.05 ± 0.01) ml/s vs. (0.04 ± 0.01) ml/s; the maximum peak flow velocity (V max) of the head and tail in the study group were lower than those in the control group: (3.14 ± 1.05) mm/s vs. (3.87 ± 1.13) mm/s, (5.56 ± 1.38) mm/s vs. (6.43 ± 1.22) mm/s, there were statistical significant ( P<0.05). There were no significant differences in the rate of reduction or disappearance of syringomyelia, the rate of no change and the rate of increase of syringomyelia after the surgery between the two groups ( P>0.05). There was no significant difference in the incidence of postoperative complications between the two groups ( P>0.05). Conclusions:Posterior fossa decompression combined with dural reconstruction in CM-Ⅰ complicated with SM can better improve cerebrospinal fluid dynamics, and promote the reduction of syringomyelia without increasing postoperative complications.
