A study on the relationship between occupational fitness, moral dilemma and resilience of nurses in emergency department / 中国实用护理杂志

Objective:To explore the correlation between nurses′ workplace adaptability, moral dilemma and resilience after suffering workplace violence in emergency department, in order to provide reference about improving the workplace adaptability and formulating intervention.Methods:A cross-section survey was conducted, we selected 248 nurses who had suffered workplace violence in the emergency department of five tertiary hospitals in Qingdao from January 2022 to January 2023 by convenient sampling method, and used self-designed general information questionnaire, moral dilemma scale, resilience evaluation scale for medical staff and nurses′ workplace adaptability scale to conduct a questionnaire survey on nurses who had suffered workplace violence, and found out the factors affecting their workplace adaptability.Results:The score of workplace adaptability of 248 nurses who had suffered workplace violence was (39.37 ± 12.77) points. Univariate analysis showed that education, length of emergency service, department or social part-time job, professional title, number of night shifts and sleep condition were the influencing factors of workplace fitness for emergency nurses ( t/ F values were -12.72 to 132.15, all P<0.05). The correlation analysis showed that the nurses′ workplace adaptability after workplace violence was negatively correlated with the scores and total scores of all dimensions of moral dilemma ( r values were -0.725 to -0.194, P<0.05), and positively correlated with the scores and total scores of all dimensions of resilience ( r values were 0.135 to 0.732, P<0.05). Multi-factor results showed that education background, department/social part-time job, working years, professional title, sleep status, moral dilemma and resilience were the influencing factors of nurses′ workplace adaptability after workplace violence ( t values were -9.25 to 15.25, P<0.05). Conclusions:Nurses with specialized education, emergency service for 1-3 years, no department/social part-time job, primary professional title, sleep disorder, higher degree of moral dilemma and low level of resilience have low occupational adaptability. Nursing managers should focus on such nurses and improve their occupational adaptability.

Subphrenic splenic implantation after splenectomy： A case report / 中南大学学报(医学版)

Subphrenic splenic implantation is a rare disease, usually occurred followed the splenic trauma and splenectomy. Surgeries are often necessary for diagnosing and treating it. A 46-year-old male post-splenectomy patient, tolerating abdominal bloating and pain for more than 1 year, was admitted to the Second Xiangya Hospital, Central South University. Fundus bulge suggested a possibility of stromal tumors originating from the muscularispropria layer with endoscopic ultrasound. Slightly stomachic thickness was detected using enhanced computed tomography (CT). Without any improvement for symptoms after medication, the patient strongly requested to undergo an endoscopic therapy. Natural orifice transluminal endoscopic surgery (NOTES) result confirmed it as subphrenic splenic implantation with postoperative pathology. In this case, NOTES helped us to confirm the diagnosis, relieve the symptoms, as well as prevent secondary surgery injury, which would be helpful to other clinicians.

Efficacy of endoscopic submucosal dissection for duodenal lesions / 中华消化内镜杂志

Objective:To evaluate the clinical efficacy and safety of endoscopic submucosal dissection (ESD) for treatment of duodenal lesions.Methods:A retrospective analysis was performed on the data of 45 patients with 46 duodenal lesions who underwent ESD at the Second Xiangya Hospital of Central South University from January 2011 to May 2019. The lesion features, en bloc resection rate, complete resection rate, complications, postoperative pathology and recurrence were assessed.Results:Among the 45 patients, 20 were males and 25 were females, with age of 52.0±11.8 years. Of the 46 lesions, 31 (67.4%) were located in the duodenal bulb, 12 (26.1%) in the descending part, and 3 (6.5%) at the junction of bulb and descending part. The diameter of the lesions was 2.4±1.9 cm. There were 14 (30.4%) lesions originated from mucosal layer, 29 (63.1%) from submucosal layer, and 3 (6.5%) from muscularis propria.Postoperative pathology showed 11 (23.9%) cases of Brunner gland tumors, 9 (19.6%) neuroendocrine tumors, 5 (10.9%) ectopic pancreas, 5 (10.9%) lipomas, and 16 (34.8%) other pathological patterns. All 45 patients with 46 lesions underwent ESD successfully, and the en bloc resection rate was 100.0% (46/46), complete resection rate was 91.3% (42/46). Intraoperative bleeding occurred in 1 case (2.2%), which was successfully treated by endoscopy. One (2.2%) delayed perforation occurred and was treated by surgical intervention. Electrocoagulation syndrome occurred in 1 case (2.2%), which was relieved after conservative medical therapy. Two cases received further surgery after ESD. The mean hospital stay was 6.2 days (ranged 2-21 days) and no death occurred. Forty-one cases were followed up for 1-78 months, with mean time of 30 months. During the follow-up period, local recurrence occurred in 1 patient (2.4%).Conclusion:ESD is an effective and safe treatment for duodenal lesions and has a good clinical practical value.

Comparison of the efficacy and safety between endoscopic submucosal dissection and radical surgery for large colorectal laterally spreading tumors larger than 5 cm in diameter / 中南大学学报(医学版)

To compare the safety and efficacy between endoscopic submucosal dissection (ESD) and radical surgery (RS) for the treatment of large colorectal laterally spreading tumors (LST) larger than 50 mm in diameter. 
 Methods: From January 2011 to January 2016, a total of 82 patients were diagnosed as large LST without deep submucosal invasion (T1 SM2, ≥1 000 µm) in the Second Xiangya Hospital of Central South University. Among them, 52 patients were treated by ESD and the other 30 patients were treated by RS [laparoscopic-assisted colectomy (LAC)/open colectomy (OC)]. The clinic data were retrospectively analyzed and the en-bloc resection rate, en-bloc R0 resection rate, local recurrence, complication, procedure time and hospital stay were collected and analyzed.
 Results: The lesion sizes were (5.80±1.20) cm and (5.53±0.69) cm in diameter for ESD and RS groups, respectively (P>0.05). En-bloc resection rates, en-bloc R0 resection rates and recurrence rates showed no significant difference between the ESD group and RS group (P>0.05). Complication rate of the ESD group (7.69%, 4/52) was much lower than that in the RS group (33.33%, 10/30; P<0.01). The ESD group also had a shorter hospital stay and operation time than the RS group (P<0.05).
 Conclusion: ESD appears to be a safe, minimal invasive and effective strategy for treating large LST and it is obviously better than RS in the aspects of hospital stay, operation time and short-term complication.

Methods A total of 60 patients with obese polycystic ovary syndrome who met the inclusion criteria were randomly divided into 2 groups, 30 patients in each group. The control group was treated with metformin, and the treatment group was treated with Heqi San on the basis of the control group. Both groups were treated for 3 months. The FPG was determined by glucose oxidase method, and fasting insulin (FINS), TC, TG, LDL-C, HDL-C level were measured by radio immunoassay, and the insulin resistance index (IR) was measured by the method of HOMA-IR. The luteotropic hormone (LH), pro follicle stimulating hormone (FSH) and testosterone (T) were detected by the automatic electrochemical light detector, and the ratio of LH/FSH was calculated. The ovarian volume and body mass index changes and clinical effect were evaluated. Results After treatment, the BMI (20.09 ± 3.12 kg/cm2 vs. 23.39 ± 1.43 kg/cm2, t=6.889), FPG (4.44 ± 0.17 mmol/L vs. 4.74 ± 0.16 mmol/L, t=6.945), FINS (10.69 ± 2.41 IU/L vs. 16.29 ± 5.95 IU/L, t=4.778), TC (3.91 ± 0.50 mmol/L vs. 4.20 ± 0.39 mmol/L, t=2.505), LDL-C (2.64 ± 0.63 mmol/L vs. 3.18 ± 0.62 mmol/L, t=3.346), LH (8.70 ± 2.44 U/L vs. 10.27 ± 2.69 U/L, t=2.934), the ratio of LH/FSH (1.33 ± 0.58 vs. 2.18 ± 0.56, t=5.775), T (1.73 ± 0.74 nmol/L vs. 2.95 ± 1.10 nmol/L, t=5.040) and ovarian volume (12.61 ± 2.29 mm3 vs. 14.26 ± 2.52 mm3, t=6.982) in the treatment group were significantly lower than those in the control group (P<0.01 or P<0.05). The FSH (7.33 ± 2.28 U/L vs. 5.95 ± 1.20 U/L, t=2.934) in the treatment group were significantly higher than those in the control group (P<0.05). The total effective rate in the treatment group was 83.3% (25/30) and 63.3% (19/30) in the control group. The difference between the 2 groups was statistically significant (χ2=3.068, P=0.050). Conclusions The Heqi San combined with metformin can effectively improve the body mass index, glucose metabolism, lipid metabolism index and sex hormone level, and reduce the volume of ovary in patients with PCOS, and the curative effect is better than that of oral metformin alone.

Summary of Clinical Experience of Professor WANG Meng-yong in Treating Uric Acid Nephropathy / 中国中医药信息杂志

To summarize the clinical experience of Professor WANG Meng-yong in the treatment of uric acid nephropathy. Professor WANG believes that the disease is mainly caused by spleen and kidney deficiency, disorder of function of Sanjiao, and pathological products, such as phlegm dampness and blood stasis and other metabolic disorders. Therefore, the treatment should distinguish symptoms and essence. Starting from pathogenesis and pathological features of spleen and kidney deficiency and phlegm dampness and blood stasis, the treatment should flexibly apply the methods of nourishing spleen and kidney, reducing phlegm and dispelling humidity, and activating blood and using diuretic of hydragogue to alleviate water retention, which can greatly reduce side effects caused by the long-term use of Western medicine and the onset of gout, and then to help disease recovery.

Background:There have been several studies about peroral endoscopic myotomy( POEM)for treating esophageal achalasia( EA). Although the feasibility,safety and effectiveness of POEM have been demonstrated,comparative studies of full-thickness and circular muscle myotomy were rare. Aims:To evaluate the efficacy and safety of POEM for treating patients with EA. Methods:A total of 216 patients with EA admitted from Aug. 2011 to Nov. 2013 at the Second Xiangya Hospital of Central South University were treated with POEM,of whom 133 received full-thickness myotomy and 83 received circular muscle myotomy. Data about Eckardt ’s score, diameter of esophageal lumen, intra- and post-operative complications and recurrence before and/or during periodical follow-up were collected,and the efficacy of full-thickness and circular muscle myotomy was compared. Results:All the 216 patients successfully underwent POEM with an average operation time of 59. 1 minutes. Average length of tunnel and myotomy were 13. 3 cm and 10. 1 cm,respectively. Symptoms remitted in all of the 216 patients,Eckardt’s score decreased significantly,diameter of esophageal lumen was reduced(pre-treatment vs. 6 months after treatment,53. 7 mm vs. 30. 8 mm,P0. 05). Conclusions:POEM is an effective and safe method for treating EA. Full-thickness myotomy did not increase the operation time and procedure-related complications, however,its long-term efficacy and complications need to be further assessed.

OBJECTIVE@#To assess the safety and efficacy of carbon dioxide (CO(2)) in colonoscopy examination.@*METHODS@#We randomized 349 patients to undergo colonoscopy with insufflation of air (n=175) or CO(2) (n=174). At colonoscopy, p (ET CO(2)) was observed at 4 time points: before the exam, arrived caecum, back rectum, and after the exam. Patient's experience of pain in the end and after the examination at 1, 3, 6, and 24 h was registered using a visual analog scale (VAS). Sedation was not used routinely.@*RESULTS@#The groups were similar in age, sex, inspection time, and caecal intubation rate (all P>0.05). There were no significant differences in p (ET CO(2)) values between the 2 groups before and after the procedure (all P>0.05). VAS scores in the CO(2) group at various time points after the examination were significantly lower than those in the air group (all P<0.05). The percent of VAS scores of 0 in the CO(2) group after 1, 3, 6, and 24 h was significantly higher than that in the air group (all P<0.01).@*CONCLUSION@#Injection of CO(2) for colonoscopy will not cause CO(2) retention, and it may significantly reduce the pain, which is safe and effective.
