Venous adventitial cystic disease(VACD)is a rare vascular disease which often manifests as unilateral limb swelling,and so misdiagnosed as other diseases such as deep vein thrombosis.Color Doppler ultrasound,CT angiography and magnetic resonance imaging play a crucial role in the diagnosis of VACD.Surgical treatment is the main method for VACD,including cyst incision,cyst wall resection,cyst puncture,aspiration and cyst and vessel resection.The recurrence rate of VACD is relatively high,ranging from 20%to 83%.Enhancing the understanding of VACD,making accurate diagnoses and appropriate surgical operation are of great significance for improving treat-ment outcomes and reducing the recurrence rate.

Objective:To explore the intervention effect of Shumu Peitu herb-partitioned moxibustion on clinical signs and symptoms and negative emotions of diarrhea-predominant irritable bowel syndrome (IBS-D) patients with liver-stagnation and spleen-deficiency pattern.Methods:A total of 72 patients with IBS-D of liver-stagnation and spleen-deficiency pattern treated in the Department of Gastroenterology of Nanjing Vniversity of Chinese Medicine from September 2021 to June 2022 were selected for randomized controlled trial. The patients were randomly divided into the observation group (2 cases dropped off, 34 cases in total) and control group (1 case dropped off, 35 cases in total) by random number table method. The patients in control group were treated with Tongxieyaofang (TXYF). The patients in observation group were treated with oral administration of TXYF and Shumu Peitu herb-partitioned moxibustion, and both groups were treated for 4 weeks. The clinical efficacy, Traditional Chinese Medicine (TCM) syndrome integral, IBS Quality of Life Questionnaire (IBS-QOL), IBS Symptom Severity Scale (IBS-SSS), Bristol Stool Form Scale and Hospital Anxiety and Depression Scale (HADS) were compared before and after treatment.Results:After treatment, the total effective rate of the observation group was 94.12%(32/34), which was higher than the 71.43%(25/35) in the control group, the difference was significant ( χ2 = 6.18, P<0.05). After treatment, the TCM syndrome integral in the observation group was (7.62 ± 4.08), which was lower than the (9.89 ± 4.71) in the control group, the difference was significant ( t = 2.14, P<0.05). After treatment of 3 days, the scores of quality of life in the five dimensions of dysthymia, behavior disorder, health worry, avoidance of eating and social function in the observation group were (82.44 ± 11.46), (80.25 ± 11.67), (76.23 ± 12.67), (59.80 ± 15.14) and (79.23 ± 11.59) points, which were different with the (73.57 ± 12.39), (72.35 ± 15.48), (69.76 ± 13.11), (50.00 ± 16.17) and (73.04 ± 13.11) points in the control group, the difference were significant ( t values were -3.09 - -2.08, all P<0.05).

The Health Promotion Lifestyle Profile Ⅱ (HPLP-Ⅱ) was used to evaluate their health promotion lifestyle status, the influencing factors were measured by general data sheet, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), disease recognition questionnaire for knee osteoarthritis patients, Social Support Rating Scale (SSRS), Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD) and Self-efficacy for Managing Chronic Disease (CDSES), respectively.Results:The total score of HPLP-Ⅱ, the total score of WOMAC, the score of disease recognition questionnaire, the total score of SSRS, the score of HAMA, HAMD, CDSES were (117.52 ± 15.58), (105.63 ± 31.64), (14.21 ± 3.23), (38.60 ± 5.18), (7.76 ± 4.41), (6.01 ± 4.54), (33.77 ± 6.04) points for middle-aged and elderly patients with knee osteoarthritis. The results of multiple linear regression analysis showed that the influencing factors were disease cognition, per capita monthly income, imaging grade, self-efficacy, support utilization, objective support, a total of 71.9% variation of regression equation could be explained.Conclusions:Middle-aged and elderly knee osteoarthritis patients health promotion lifestyle score at a low level, to improve, affected by disease cognition, imaging grading, self-efficacy, social support, medical staff should combine the degree of disease and individualized factors for disease health education, improve patients′ self-efficacy and social support level, prompting patients to adopt a healthy lifestyle.

Objective: To investigate the role of epidemiological history in the screening of Corona Virus Disease 2019 (COVID-19) in fever clinic, to improve the efficiency in fever clinic and reduce the incidence of cross infection. Methods: This is a retrospective study. Patients who were admitted to the fever clinic in West China Hospital of Sichuan University from January 23^th, 2020 to February 11^th, 2020 included the study. According to epidemiological history, the patients were divided into epidemiological history group (the experimental group) and no epidemiological history group (the control group). The two groups of patients were admitted and treated separately. The clinical data, NEWS score, etiology results, viral pneumonia showed on CT, time of visit, COVID-19 patient ratio, and admission composition ratio were compared between the two groups. The measurement data were presented as the mean ± standard deviation (SD), and the numeration data were expressed as ratio or constituent ratio. The measurement data of normal distribution between the two groups were compared by independent sample t test. The measurement data of skewed distribution are expressed by the median (interquartile range), and the comparison between the two groups is tested by non-parameter. The differences between enumeration data were assessed by chi-square test. A P<0.05 was considered statistically significant. Results: A total of 2423 patients were included, including 927 patients in the experimental group and 1296 patients in the control group. There were no significant differences in gender, NEWS score and clinical symptoms between the two groups (P> 0.05). The age (35.00 ± 12.80 vs 38.13 ± 15.57 years) , the proportion of fever patients (28.80% vs 32.75%) and waiting time (31.72 vs 58.08 min) of the experimental group were lower than the control group, the difference was statistically significant (P <0.05). The CT examination ratio (37.54% vs 20.39%), viral pneumonia ratio showed on CT (9.77% vs 2.95%), ratio of examined COVID-19 nucleic acid test (85.44% vs 56.75%), and the admission ratio (16.72% vs 9.63%) of the experimental group were higher than the control group, and the differences were statistically significant (P <0.05); There was no significant difference in the positive rates of influenza virus and rhinovirus between the two groups (P> 0.05). Conclusion It is necessary to adjust the management mode of fever clinic during the Corona Virus Disease 2019, and to manage the patients according to the epidemiological history which can improve the screening efficiency and reduce the risk of cross infection.

Objective:To understand the current situation and influencing factors of successful aging in widowed elderly.Methods:From May to October 2019, 225 widowed elderly people were investigated by questionnaire in 7 communities and 5 villages in Shandong Province. The Successful Aging Scale of the Flood was used to assess their successful aging status. The general data sheet, Physical Activity Scale for the Elderly (PASE), Multidimensional Scale of Perceived Social Support(MSPSS), Connor-Davidson Resilience Scale (CD-RISC) and Mini Mental State Examination(MMSE) were used to measure its influencing factors.Results:The successful aging score of the widowed elderly was 46.22 ± 9.49. The results of multiple linear regression analysis showed that the influencing factors of the successful aging of the widowed elderly were: social activity participation, household registration, consciously successful aging status, psychological resilience, MMSE—attention and computing power, perceived social support—other people, leisure physical activity, which can explain a total of 70.7% of the regression equation.Conclusions:The successful aging status of widowed old people is at a low level, and its influencing factors have both common factors and specific characteristics compared with those with spouses. In particular, more attention should be paid to "participation in social activities", and the widowed old people should be actively encouraged to participate and improve their successful aging.

Objective:To explore the effect of artificial intelligence teaching-picture system in training the bone marrow cell morphological reading ability of clinical medical students.Methods:A total of 110 five-year undergraduate students were divided into experimental group (artificial intelligence picture teaching method) and control group (traditional teaching method) in the bone marrow cell morphology reading ability training. On the basis of multimedia teaching, the experimental group was given the teaching by using the bone marrow cell morphology picture storage and transmission system for retrieval, learning and computer adaptive test. Then objective evaluation of image recognition ability and questionnaire were used to compare the teaching effect.Results:The image recognition ability was significantly better in the experimental group than in the control group [(89.6±5.7) vs. (81.4±4.9), P<0.01]. Furthermore, the experimental group showed more obvious advantages in cell morphology recognition [(74.7±4.0) vs. (68.7±4.9)] and diagnosis of hematological diseases [(14.9±3.0) vs. (12.9±2.4)] than the control group (both P<0.01). Questionnaire survey showed that the students expressed their affirmation and support for the artificial intelligence teaching-picture system in the bone marrow cell morphological reading ability training. Conclusion:The application of artificial intelligence teaching-picture system can greatly improve the teaching effect, mobilize students' learning enthusiasm and expand learning resources, which is worthy of further promotion and application.

Objective To explore the impacts of clinical pulmonary infection score (CPIS) on duration and defined daily doses (DDDs) of antibiotics in patients with bacterial severe pneumonia in intensive care unit (ICU). Methods Patients with severe pneumonia, whose antibiotic usage was prescribed with the guide of CPIS, and admitted to ICU severe respiratory and infectious disease ward of Guizhou Medical University Affiliated Hospital from May 2017 to October 2017 were enrolled as CPIS group. Patients with the first CPIS score > 5 were given antimicrobial therapy, and the score was dynamically evaluated every 2-3 days. If the CPIS score < 5, the score was evaluated again after 2 days. If the score was still < 5, the antimicrobial drugs were discontinued. Patients admitted to the same ward from November 2016 to April 2017 were regarded as controls, of whom the antibiotic usage was completely conducted by the clinical experience of the chief physician. The duration and DDDs of antibiotics were compared between patients in two groups. At the same time, the usage of ventilator and prognostic indicators (the length of ICU stay, ICU mortality) were recorded. Kaplan-Meier survival curve was drawn, and the cumulative survival rates of 28 days, 90 days and 12 months were analyzed and compared between the two groups. Results In our department, 177 and 182 patients were admitted to ICU from November 2016 to April 2017 and from May 2017 to October 2017, respectively, of whom 101 and 65 patients with severe pneumonia were collected respectively during the two stages. There was no significant difference in gender composition, age, underlying diseases, vital signs, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score, or peripheral blood routine at admission between the two groups, indicating that the baseline data of the two groups were equally comparable. During the treatment process, there was no significant difference in the duration of mechanical ventilation [hours: 126.0 (69.0, 228.8) vs. 120.0 (72.0, 192.0)], the length of ICU stay [days: 7.0 (5.0, 11.0) vs. 8.0 (5.0, 14.0)], or ICU mortality [18.8% (19/101) vs. 26.2% (17/65)] between the control group and CPIS group (all P >0.05). Kaplan-Meier survival curve analysis showed that there was no significant difference in the cumulative survival rate of 28 days (log-rank test: χ2 = 0.540, P = 0.462), 90 days (log-rank test: χ2 = 0.332, P = 0.564) or 12 months (log-rank test: χ2 = 0.833, P = 0.362). Patients from CPIS guided group, however, had a shorter duration of antibiotics usage (days: 7.54±4.81 vs. 9.88±4.96, P < 0.01), and had a lower DDDs of antibiotics (17.58±13.09 vs. 22.73±18.31, P < 0.05) as compared with those in the control group. Conclusion CPIS-guided therapeutic regimen shortens antibiotic duration and decreases antibiotic DDDs in patients with severe pneumonia in ICU, indicating the values of CPIS in guiding antibiotics usage in these patients.

This study was aimed to evaluate the clinical effect and safety of Qing-Fei Tong-Luo (QFTL) ointment for treating children with pneumonia.Randomized controlled trial (RCT) was conducted among 460 cases of children with pneumonia.The observation group was given QFTL ointment combined with basic treatment.And the control group was only treated by basic treatment.Evaluation was given on the total clinical efficacy,disappeared time of fever,cough,expectoration,shortness of breath,and medication safety.The incidence of respiratory diseases was followed up on the 30th days after drug withdrawal.The results showed that in the aspect of clinical efficacy between two groups,the cure rate of the observation group was 98.26％,and that of the control group was 93.89％,with statistic significance (P ＜ 0.05).The cure rate of the observation group was better than that of the control group.There was statistical difference on expectoration disappeared time (P ＜ 0.05).There was no statistical difference on disappeared time of fever,cough and shortness of breath (P ＞ 0.05).There was statistical difference on the incidence of respiratory diseases on the 30th days followed-up after drug withdrawal (P ＜ 0.05).There was no statistical difference on the incidence of upper respiratory tract infection,pneumonia and asthma (P ＞ 0.05).No adverse reactions occurred in the observation group.It was concluded that QFTL ointment combined with basic therapy on the treatment of pneumonia in children was significantly better than the control group in the aspect of clinical efficacy,expectoration disappeared time and the incidence of bronchitis.It is safe and effective.The prognosis is good and worthy of promotion in the clinical practice.

Objective To compare the efficacy and safety of endoscopy and laprotomy for gastric stromal tumor,and to evaluate the clinical value of endoscopy.Methods A retrospective analysis was made based on the clinical data of 142 patients with gastric stromal tumor(diameter＜3 cm with clear boundary),with 83 patients who underwent endoscopic resection assigned to the endoscopy group,and 59 patients who underwent laprotomic resection to the operation group.The clinical and pathological data in both groups were analysed and the safety,perioperative situation and prognosis of two groups were compared.Results Compared with the laprotomy group,the endoscopy group required the same time,[(88.25±12.18) min VS (90.15±10.25) min,P=0.367],yielded to less intraoperative blood loss[(42.15±22.13) ml VS (140.55±35.66) ml,P＜0.01],early postoperative feeding[(2.30± 1.20) d VS (5.40± 1.28) d,P＜0.01],and shorter postoperative hospital stay [(5.43± 1.78) d VS (9.42± 1.65) d,P＜0.01].Follow-up was performed in two groups for 5-55 months (median,30 months),with no recurrence or metastasis.Conclusion Compared with surgery,endoscopic therapy is safe and effective for the gastric stromal tumor,whose diameter is less than 3 cm with clear boundary.
