Objective To summarize research status of correlation of chronic lymphocytic thyroiditis (CLT) and papillary thyroid carcinoma (PTC), in order to provide a basis for early diagnosis, prognosis, and prevention of PTC. Method The literatures about the recent studies of the correlation of the CLT and PTC were reviewed according to the results searched from PubMed database, SpringerLink database, Web of Science database, Wanfang database, CNKI database, and VIP database. Results The most of patients with CLT combined with PTC are young women, the characteristics are multifocal and occult, the prognosis is good. Its genesis might be related to the ionizing radiation, iodine intake, endocrine disorders, immune disorders, molecular biology, and other factors. But there are still different controversies about its specific pathogenesis and surgical treatment. Conclusions CLT is closely related to PTC. However, relationship between CLT combined with PTC and changing regularity of molecular biology, pathogenesis, or prognosis needs further to be studied and followed-up for a longer-term.

Objective To explore the application effects of innovative health education on patients undergoing ambulatory laparoscopic cholecystectomy (LC). Methods A total of 139 patients undergoing ambulatory LC from November to December 2016 were selected as the control group, receiving the traditional health education; and other 141 patients undergoing ambulatory LC from February to March 2017 were selected as the observation group, receiving the innovative health education. The two groups were followed up and observed 1 day, 2, and 28 days after the discharge, and the incidence rates of adverse reactions such as postoperative pain, bleeding and incision infection were measured, and the disease knowledge mastery, self-care skills, medication compliance and satisfaction to nursing and hospital were evaluated. Results The total incidence rate of adverse reactions was 7.8% in the observation group and 25.2% in the control group (P<0.001). Medication compliance from high to low was 90, 46 and 5 cases in the observation group and 59, 64 and 16 cases in the control group (P<0.001). In the observation group, the scores of disease knowledge mastery, self-care cognition, nursing satisfaction and hospital satisfaction were 93.4±5.5, 91.4±4.5, 96.4±3.7 and 98.1±3.7, respectively, which were higher than those in the control group (83.8±8.7, 83.2±9.1, 91.5±9.2 and 94.8±7.3, respectively) with statistical significance (P<0.001). Conclusion Innovative health education has certain application effects on ambulatory LC, and it can significantly improve disease knowledge mastery and self-care cognition, and help to ensure the medical quality and safety during perioperative period, and improve the patients’ satisfaction.
ObjectiveTo review the development and clinical application of ankle prosthesis.MethodsThe recent literature on ankle prosthesis design and clinical application was reviewed and analyzed. ResultsCompared with the hip and knee prostheses, the ankle prosthesis develops slowly and has been developed to the third generation. The ankle joint has a special structure of multi-axis movement. The design of the first and second generations of prostheses is not conformed to the biomechanics of the ankle. The third generation of prosthesis is more conform to the characteristics of ankle biomechanics, with high postoperative survival rate and satisfactory clinical outcome. ConclusionAt present, the survival rate of ankle prosthesis is low, and there is still much room for improvement in biomechanics, materials, and other aspects.
With the in-depth understanding of the severe acute respiratory syndrome coronavirus 2, it has been found that the virus not only causes serious damage to the human respiratory system, but also damages the kidney system, which can be manifested as acute kidney injury, and in severe cases, renal failure can occur. Patients with coronavirus disease 2019 and chronic kidney disease are at higher risk of worsening their condition and even death. Therefore, early recognition and intervention of renal injury is particularly important for prognosis. In this paper, the clinical data of renal injury in patients with coronavirus disease 2019 were reviewed, and the possible pathogenesis, incidence, clinical features, diagnosis and treatment were proposed for reference in clinical decision-making.

Objective To explore the clinical therapeutic value of pancreatoduodenectomy in patients with carcinoma of ampulla of Vater (AVC). Methods The clinical data of 195 patients with AVC between March 1995 and March 2009 in this hospital were analyzed retrospectively. All the patients were divided into non-surgery group (n＝51), palliative surgery group (n＝96), and resection group (n＝48) according to the treatment methods. Results The 1-year, 3-year, and 5-year survival rates in the resection group were higher than those in the non-surgery group and the palliative surgery group (Plt;0.01). However, the incidence of complications in the resection group was higher than that in the nonsurgery group or the palliative surgery group (Plt;0.05). The radical resection rates, 1-year, 3-year, and 5-year survival rates of carcinomas of head of pancreas were significantly lower than those of carcinomas of the terminal of common bile duct or carcinomas of duodenal papilla (Plt;0.05, Plt;0.01). There was no significant difference of the perioperative mortality, complications rate, 1-year, 3-year, or 5-year survival rate between preoperative drainage jaundice group and preoperative nondrainage jaundice group (Pgt;0.05). The perioperative mortality in the resection group above the age of 70 years old was higher than that of less than or equal to 70 years old （Plt;0.05）. Compared with the non-surgery group or palliative surgery group, there were significant increasement of the incidence of serious or deadly perioperative complications in the resection group (Plt;0.05). Conclusions Surgical resection remains one of the most important measures of the treatment of AVC, in particular, the radical pancreatoduodenectomy is the only effect way for AVC, thus significantly prolonging the patient’s postoperative survivals and significantly improving the qualities of life.
Objective To explore the risk factors of perioperative insomnia in young patients with breast masses undergoing ambulatory Mammotome (MMT) minimally invasive surgery. Methods A total of 166 young female patients who were ≤40 years old, diagnosed with breast masses, undergoing ambulatory MMT between June and December 2016 in West China Hospital of Sichuan University were included in this study. Questionnaire survey and data about general condition, preoperative and postoperative Insomnia Severity Index (ISI), Hospital Anxiety and Depression Scale, and postoperative pain Visual Analogue Scale were collected in the enrolled population. Univariate analysis was used to screen the factors that might cause insomnia, and then multiple logistic regression analysis was performed to identify possible risk factors of insomnia. Results In the 166 young female patients, the mean age was (30.90±5.96) years, and the mean perioperative ISI score was 8.83±4.97. Slight insomnia was found in 39.7% (66/166) of the patients, moderate insomnia was found in 12.7% (21/166), and severe insomnia was found in 2.4% (4/166). The results of multiple logistic regression suggested that the number of breast masses [taking the number=1 as the reference, when the number=4, odds ratio (OR)=2.269, 95% confidence interval (CI) (1.917, 13.818), P=0.001; when the number>4,OR=9.359, 95%CI (4.507, 19.433), P<0.001] and the maximum diameter of breast masses [taking 1–10 mm as the reference, when the maximum diameter was 26–30 mm,OR=6.989, 95%CI (1.488, 32.785), P=0.014; when the maximum diameter >30 mm, OR=17.290, 95%CI (4.664, 64.071), P<0.001] were independent risk factors of the severity of perioperative insomnia in these young women. Conclusion It is recommended that psychological nursing and comprehensive admission education should be enhanced for young patients who have >3 breast masses or the diameter of the mass is >25 mm, aiming to improve the postoperative recovery of patients with high risk of insomnia.
Objective To analyze clinical and pathological features of patients with papillary thyroid carcinoma (PTC) with coexistent chronic lymphocytic thyroiditis (CLT). Methods The clinicopathologic data of 756 cases of PTC were collected from January 2014 to January 2017 in the First Affiliated Hospital, Xinjiang Medical University were collected. The patients were designed to observational group (PTC with coexistent CLT, n=194) and control group (simple PTC, n=562) according to whether CLT was diagnosed by pathology, then the clinical data, ultrasonic features, thyroid function, and pathological features in these two groups were compared. Results The proportion of the female patients, the proportions of theserum thyroid stimulating hormone and thyroid autoimmune antibodies (thyroglobulin antibody and thyroid peroxidase antibody), and the proportion of multifocal carcinoma in the observational group were significantly higher than those in the control group (P<0.05). There were no significant differences in the preoperative ultrasound, tumor diameter, thyroid capsule invasion, central lymph node metastasis, and TNM stage in these two groups (P>0.05). The results of the multivariate analysis showed that the female, serum thyroid autoimmune antibodies, and the multifocal carcinoma were the independent predictive factors of PTC with CLT (P<0.05). Conclusions There might be a certain correlation between PTC and CLT, PTC with coexistent CLT is more common in female patient and with multifocal carcinoma. With coexistent CLT does not increase invasion of PTC. This may be associated with limit of CLT to development of PTC nodules. It is speculated that CLT may be a protective factor of PTC.
