Objective To observe the difference of anoreetal dynamics between Milligan-Morgan hemorrhoidectomy plus internal sphinctemtomy and simple Milligan-Morgan bemorrhoidectomy in the treatment of annulus mixed hemorrhoids.Method Measured the anal resting pressure,maximal anal contractive pressure,rectal sensation thresholds,maximal rectal tolerable dose and maximal rectal compliance 1 day before and 3 months after Milligan-Morgan hemorrhoidectomy plus internal sphincterotomy (therapy group,50 cases)and simple Milligan-Morgan bemorrhoidectomy(control group,52 cases)by anorectal manometric device made in Sweden.Results The anal resting pressures of therapy group and eontrol group reduced signifieanfly 3 months after operation compared with that 1 day before operation(P＜ 0.01 or ＜ 0.05),but there was significant difference between the two groups in 3 months after operation(P＜0.05).The maximal anal contractive pressure,reetal sensation thresholds,maximal rectal tolerable dose and maximal rectal compliance were no significant difference between the two groups in 3 months after operation (P ＞0.05).Conclusion Anal sphineterotomy can change the high anal pressure significantly in the treatment of annulus hemorrhoids without copracrasia,it is a proper operation method.

Objective:To observe any effect of electroacupuncture applied to the Jialianquan points in treating post-stroke oropharyngeal dysphagia.Methods:Forty-five stroke survivors with oropharyngeal dysphagia were randomly divided into an electroacupuncture group ( n=15), a neuromuscular electrical stimulation group ( n=15) and a control group ( n=15). All groups received 30 minutes of routine swallowing function training 5 times a week for 3 weeks. The electroacupuncture group was additionally provided with 30 minutes of electroacupuncture applied to the Jialianquan (CV23) points, and the neuromuscular electrical stimulation group instead received 30 minutes of neuromuscular electrical stimulation over the bilateral submental muscles. Videofluoroscopic swallowing studies were performed before and after the 3 weeks of treatment. Standardized swallowing assessment was conducted producing functional oral intake scale ratings, modified barium swallow impairment profiles and the penetration-aspiration scale scores. Surface electromyography was also employed to evaluate submental muscle functioning through measuring the swallowing time, average EMG (AEMG) value and peak amplitude. Results:After the treatment, significant improvement was observed in all of the evaluations with both groups, but the average scores were significantly better in the electroacupuncture and neuromuscular electrical stimulation groups compared with the control group and significantly better in the electroacupuncture group than in the neuromuscular electrical stimulation group.Conclusion:Electroacupuncture at the Jialianquan point can significantly improve the swallowing of stroke survivors with oropharyngeal dysphagia. It is more effective than neuromuscular electric stimulation.

Objective:To observe any effect of transcranial direct current stimulation (tDCS) on the cognition of stroke survivors and the integrity of their white matter fibers.Methods:Thirty persons with post-stroke cognitive impairment (PSCI) were randomly divided into an experimental group ( n=15) and a control group ( n=15). In addition to basic drug therapy and routine cognition training, the experimental group received 20 minutes of tDCS daily, 5 days per week for 3 weeks, while the control group received sham tDCS stimulation. Before and after the treatment, both groups′ cognitive functioning was evaluated using the mini-mental state examination (MMSE) and the Montreal cognitive assessment scale (MoCA). Their ability in the activities of daily living (ADL) was quantified using the modified Barthel index (MBI). Diffusion tensor imaging (DTI) was employed to observe any changes in the integrity of their white matter fibers. Results:The average MMSE, MOCA and MBI scores of both groups had improved significantly after the treatment, but the improvement in the experimental group was significantly greater than among the controls. The average fractional anisotroposy value of the affected inferior fronto-occipital fasciculus in both groups was positively correlated with the group′s average MMSE score and MoCA score.Conclusion:tDCS can effectively improve the cognition and functioning in the activities of daily living of stroke survivors. Its mechanism may be related to improving the integrity of the white matter fibers involved.

Objective To determine the diagnostic value of endoscopic ultrasound-guided fine needle aspiration ( EUS-FNA ) for gastrointestinal lesions with inconclusive endoscopic biopsies. Methods A retrospective analysis was performed in 65 patients who were found to have gastrointestinal lesions with inconclusive endoscopic biopsies and underwent EUS-FNA in Drum Tower Hospital. Diagnostic value of EUS-FNA was determined by comparing with surgical histopathology and follow-up results. Results This study included 41 males ( 63％) and 24 females ( 37％) with median age of 60 years. The most common lesion was diffuse infiltrative lesions ( 37, 56. 9％) , followed by submucosal protrusion types ( 17, 26. 2％) . Fifty-four cases ( 83. 1％) were malignant lesions, and 11 cases ( 16. 9％) were benign. The overall sensitivity, specificity, and accuracy of EUS-FNA for gastrointestinal lesions with inconclusive biopsies were 76. 8％ ( 95％CI: 65. 7％-87. 8％) , 100. 0％ ( 95％CI: 66. 4％-100. 0％) , and 80. 0％( 95％CI: 70. 3％-89. 7％) , respectively. Sub-group analysis showed the sensitivity, specificity, and accuracy of EUS-FNA for diffuse infiltrative lesions were 70. 6％ ( 95％CI: 55. 3％-85. 9％, 100. 0％( 95％CI:29. 2％-100. 0％) , and 73. 0％ ( 95％CI: 58. 7％-87. 3％) , respectively. For submucosal protrusions, the sensitivity, specificity, and accuracy of EUS-FNA were 68. 8％ ( 95％CI: 46. 0％ -91. 5％) , 100. 0％ ( 95％CI: 2. 5％-100. 0％) , and 70. 6％ ( 95％CI: 44. 0％-89. 7％) , respectively. Conclusion EUS-FNA has moderate diagnostic value for endoscopic biopsy-inconclusive gastrointestinal lesions. It can be an alternative option when standard methods, such as endoscopic mucosal forceps biopsy, fail to provide a definitive diagnosis.

Objective:To develop an online interactive cytopathological training program, and to evaluate it for improving the cytopathological diagnostic ability of endoscopists in endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) of pancreas.Methods:A total of 5 500 cytopathological images were collected from 194 patients with pancreatic solid mass who underwent EUS-FNA in Nanjing Drum Tower Hospital from August 2018 to August 2019. The cell type in each cytopathological picture was labeled by senior cellular pathologists, which was used to build a learning and testing platform for online interactive cytopathological training. Five endoscopists without cytopathological background were invited to participate in this training. Sensitivity, specificity, positive predictive value and negative predictive value of endoscopists in differential diagnosis of cancer and non-cancer before and after training were compared to evaluate the effect of the online interactive cytopathological training program on improving the ability of endoscopists in diagnosis of cytopathology.Results:A cytopathological training platform for endoscopists to learn and take online test was successfully built. Before training, sensitivity, specificity, positive predictive value, negative predictive value and accuracy of diagnosis of cancer and non-cancer for endoscopists were 0.55 (95% CI: 0.53-0.58), 0.32 (95% CI: 0.30-0.35), 0.43 (95% CI: 0.41-0.45), 0.44 (95% CI: 0.41-0.47) and 0.43 (95% CI: 0.42-0.45), respectively. After training, the above indicators were 0.96 (95% CI: 0.95-0.97), 0.70 (95% CI: 0.68-0.73), 0.74 (95% CI: 0.72-0.76), 0.95 (95% CI: 0.94-0.96) and 0.81 (95% CI: 0.80-0.83), respectively, which were significantly improved compared with those before ( P<0.001). Conclusion:The online interactive cytopathological training program can improve the understanding and diagnostic ability of endoscopists in pancreatic cytopathology, help to implement rapid on-site evaluation in the process of EUS-FNA, and improve the diagnostic efficiency of EUS-FNA.

Objective:To understand the sleep quality and mental health status of nurses in public health emergencies, and analyze the correlation between them.Methods:A total of 128 first-line nursing staff participating in public health emergencies on February 22-23, 2020 in Tianjin Beichen Hospital, Tianjin First Central Hospital, Tianjin Fourth Central Hospital were investigated by the general data questionnaire, Pittsburgh Sleep Quality Index (PSQI), and Symptom Checklist 90 (SCL-90).Results:70.3%(90/128) of nursing staff had poor sleep quality, and the total score of PSQI was (9.71±4.01) points, which was statistically significant compared with the domestic norm ( t value was 16.479, P<0.01). The total score of SCL-90 was 1.59±0.52, which was statistically significant compared with the domestic norm ratio ( t value was 4.505, P<0.01). One-way ANOVA showed that the nursing staff's age had a significant impact on sleep quality, and the difference was statistically significant ( F value was 4.092, P<0.05). Pearson correlation analysis showed that the Pittsburgh sleep quality scale index scores and symptom self-assessment scale and somatization, force, sensitive interpersonal relationship, depression, anxiety, hostile, terrorist, paranoia, and psychosis were positively correlated( r values were 0.292-0.444, P< 0.01). Conclusions:The sleep quality and mental health status of nurses in public health emergencies are poor, and the sleep quality is correlated with mental health status.
