Objective: To evaluate the effect of Triangle hierarchical management among community patients with hypertension, so as to provide insights into the improvements of standardized hypertension management. Methods: Patients with newly diagnosed hypertension from 2 community health service centers in Qiantang District of Hangzhou City by the end of 2020 were randomly assigned to the conventional group and the Triangle group. Patients in the conventional group were given health management services according to the requirements of basic public health service standard for one year, while patients in the Triangle group were given Triangle hierarchical management. The blood pressure, self-management behaviors, treatment compliance, smoking, alcohol consumption and exercise were collected using the self-management behavior scale, treatment compliance scale and self-designed questionnaires, and were compared before and after intervention with analysis of covariance and generalized estimation equations. Results: Totally 200 patients with hypertension were recruited, including 100 patients in the conventional group and 100 patients in the Triangle group. There were no significant differences between the two groups before implementation of interventions in terms of gender, age, educational level or occupation (P>0.05). The reduction in blood pressure, increase in the score of treatment, diet, exercise and living habitat management and the total score of self-management behaviors, increase in the score of adherence to medication regimens, daily living management behaviors, smoking and alcohol consumption preference and the total score of treatment compliance, and increase in the number of patients with normal standard of quitting smoking, quitting alcohol consumption, exercise and blood pressure were significantly higher in the Triangle group than in the conventional group after intervention (P<0.05). Conclusions Triangle hierarchical management may increase the treatment compliance, improve the self-management behavior and facilitate hypertension control among hypertensive patients, which may be popularized for health management among community patients with hypertension.

OBJECTIVES: Radiation therapy is a main method for female pelvic malignancies, which can cause some adverse reactions, such as radiation proctitis (RP). The incidence of RP is highly positively correlated with radiation dose. There is an urgent need for a scientific method to accurately predict the occurrence of RP to help doctors make clinical decisions. In this study, based on the clinical data of female pelvic tumor patients and dosimetric parameters of radiotherapy, the random forest method was used to screen the hub features related to the occurrence of RP, and then a machine learning algorithm was used to construct a risk prediction model for the occurrence of RP, in order to provide technical support and theoretical basis for the prediction and prevention of RP. METHODS: A total of 100 female patients with pelvic tumors, who received static three-dimensional conformal intensity-modulated radiation therapy in the Department of Radiation Oncology of the Affiliated Hospital of Xiangnan University from January 2019 to December 2020, were retrospectively collected, and their clinically relevant data and radiotherapy planning system data were collected. During radiotherapy and 18 months after radiotherapy, 35 cases developed RP (RP group), and the remaining 65 cases had no RP (non-RP group). The clinical and dosimetric characteristics of patients were ranked by the importance of random forest algorithm, and the independent prognostic characteristics associated with the occurrence of RP were selected for machine learning modeling. A total of 6 machine learning algorithms including support vector machines, random forests, logistic regression, lightweight gradient boosting machines, Gaussian naïve Bayes, and adaptive enhancement were used to build models. The performance of the model was evaluated by the area under the receiver operating characteristic curve (AUC), accuracy, sensitivity, specificity, positive predictive value, negative predictive value, and F1 score. Finally, the random forest model was determined as the prediction model, and the calibration curve and decision curve of the prediction model were drawn to evaluate the accuracy and clinical benefit of the model. RESULTS: The parameters for random forest prediction model in the training set were as follow: AUC, 1.000, accuracy, 0.988, sensitivity, 1.000, specificity, 1.000, positive predictive value, 1.000, negative predictive value, 0.981, and F1 score, 1.000. In validation set, AUC was 0.713, accuracy was 0.640, sensitivity was 0.618, specificity was 0.822, positive predictive value was 0.500, negative predictive value was 0.656, and F1 score was 0.440. Random forest showed high predictive performance. Moreover, the Brief of the calibration curve for the prediction model was 0.178, the prediction accuracy was high, and the decision curve showed that the prediction model could benefit clinically. CONCLUSIONS Based on the clinical and dosimetric parameters for the female pelvic tumor patients, the prediction model of radiation proctitis constructed by random forest algorithm has high predictive ability and strong clinical usability.

Objective:To explore the expression of peptidyl prolyl cis-trans isomerase (Pin1) activity in peripheral blood of patients with rheumatoid arthritis (RA) and the value and correlation of T helper cell 17/regulatory cells (Th17/Treg) cells, and to analyze the effect and influence of all-transretinoic acid (ATRA) on it.Methods:① Comparing the difference of Pin1 expression and absolute counts of Th17 and Treg between RA patients before and after treatment and healthy control group, Kruskal-Wallis rank sum test was used for analysis. ② To analyze the correlation between the expression of Pin1 and its general data, activity indicators [such as erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and disease activity score 28 joints (DAS28) scores], Th17, Treg and some cytokines in RA patients, and to use Pearson and Spearman correlation tests. ③ To analyze the difference of Pin1 expression and Th17/Treg in peripheral blood of RA patients treated with low-dose all-trans retinoic acid (10 mg twice a week) and traditional immunosuppressants such as hydroxychloroquine for 3 months respectively. Mann-Whitney U test was used for comparison between the two groups, and the difference was statistically significant with ( P<0.05). Results:① The activity of Pin1 in peripheral blood of the newly treated group of RA was [13.62(9.16, 19.42)] higher than that of the healthy control group [8.97(7.62, 11.45)]( Z=42.82 , P<0.05), and Th17 was [18.28(12.76, 24.08)] higher than that of the healthy control group [6.04(4.96, 4.96)]( Z=48.83 , P<0.05). Treg [11.06(5.31, 21.87). It was lower than that of healthy control group [40.41(24.33, 48.52)]( Z=42.21 , P<0.05). ② the activity of Pin1 in peripheral blood of RA patients was positively correlated with CRP, the number of involved joints, DAS28 score, interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) ( r=0.396, P<0.05; r=0.683, P<0.05; r=0.466, P<0.05; r=0.315, P<0.05; r=0.416, P<0.05). ③ Compared with the newly treated RA group, the activity of Pin1 [6.94(5.96, 8.77), Z=42.82 , P<0.05] and Th17 7.38 decreased [7.38(3.85, 11.21), Z=48.83 , P<0.05], while Treg [40.41 (17.77, 33.47)] increased ( Z=42.21 , P<0.05). ④ Compared with the traditional medicine group, Treg [28.9(21.73, 37.36)] was higher in the retinoic acid group, and the difference was statistically significant ( Z=-2.683 , P<0.05). The activity of Pin1 was [6.23(5.58, 8.75)], but there was no statistical significance ( Z=-1.622 , P=0.104). Conclusion:Pin1 in peripheral blood of RA patients is over-expressed. Th17 is increased and Treg is decreased. ATRA combined with other traditional drugs can reduce Pin1 activity, promote Treg growth and improve disease activity of RApatients to a certain extent.

Objective:Dorsocervical fat pad is common in middle-aged women. Current treatments include surgical excision and liposuction. We evaluated the therapeutic effect of tumescent liposuction on dorsocervical fat pad. Anatomical study was also carried out to explore the anatomical structure and significance of dorsocervical fat pad.Methods:From Jan. 2009 to Dec. 2018, twenty-seven patients with dorsocervical fat pad were treated with tumescent liposuction in Peking University Third Hospital. Small incisions were made in bilateral scapular region and 4 mm suction cannula was applied. A female cadaver fixed with formaldehyde was dissected to investigate the structure of posterior cervical and dorsal region. The specimens were stained with HE and Masson staining.Results:14 patients were followed up for no less than 6 months, with an average follow-up time of 27 months. Patients＇ dorsocervical area were flat and smooth after the surgery. Patient satisfaction rate was 100% and no severe complication was reported except bruise and pain. The symptoms of dorsocervical pain in two patients were significantly improved after operation. Anatomical study showed that the dorsocervical fat pad was composed of superficial and deep layer of adipose tissue, with clear boundary between the two layers and no obvious capsule. The collagen fibers in deep layer were more and denser than those in superficial layer.Conclusions:Tumescent liposuction can effectively treat dorsocervical fat pad. The surgery outcome is ideal with little complication.Through the study of the anatomical structure of the dorsocervical fat pad, the operation method and principle of liposuction can be improved and the operation efficiency can be enhanced.

Objective To investigate the knowledge,attitude,and behavior of patients with chronic kidney disease(CKD)in the community.Methods A questionnaire survey on knowledge,attitude and behavior through the mobile WeChat was conducted among 1 006 CKD patients in 57 villages of Jinze and Huaxin communities in Shanghai Qingpu district from June 2016 to May 2018,and the results were analyzed.Results The accuracy rate about CKD knowledge in 1 006 CKD patients was 69.98％.The participants who were very willing to accept referral,learning CKD knowledge,periodic follow-up,health education and lifestyle counseling accounted for 60.40％,those who were willing accounted for 32.59％ and not willing for 7.01％.The survey of behavioral patterns showed that 29.17％ often participated in actively learning disease knowledge,periodic follow-up and counseling,reasonable diet and regular exercise;52.96％ occasionally participated and 17.87％ never participated.There were no significant differences in knowledge about CKD among patients of different sex,age and occupation(t=0.475,F=7.111,F=0.563;all P＞0.05);while the CKD knowledge level was higher in patients with college or above educational levels(7.80± 3.96),or patients with a disease history over 5 years(7.64 ± 2.84),or patients with stage 5 CKD(8.25 ± 1.16).Conclusion The rate of knowledge,attitude and behavior in CKD patients is relatively low,especially in attitude and behavior.In order to control the disease progression and reduce the adverse impact of the disease,it is necessary to take effective measures to improve the attitude and behavior of CKD patients.

OBJECTIVE: To investigate the prognostic value of metabolic tumor volume (MTV) and total lesion glycolysis (TLG), measured by preoperative ¹⁸F-fluorodeoxyglucose positron emission tomography/computed tomography (¹⁸F-FDG PET/CT), in risk stratification of patients with endometrial carcinoma (EC). METHODS: The patients with pathological diagnosis of EC who underwent preoperative ¹⁸F-FDG PET/CT imaging were retrospectively selected for analysis of the prognostic values of PET parameters in risk classification and lymph node metastases (LNMs). Receiver-operating-characteristic analysis was used to analyze the correlation of PET parameters cutoff values with deep myometrial invasion (MI), lymphovascular space involvement and LNM for prognostic values in risk stratification. RESULTS: The sensitivity, specificity, positive predictive value, negative predictive value and accuracy for detection of LNM are 83.3%, 99.7%, 90.9%, 99.5% and 99.2%, respectively. The MTV and TLG of primary lesion of EC in the patients with LNM are notably higher than those in patients without LNM, p<0.010. The MTV and TLG of the EC primary lesions in high-risk patients are significantly higher than those in low-risk patients (p<0.010), but the maximum standardized uptake value (SUVmax) is not. The MTV and TLG of primary lesions were superior to SUVmax for predicting of deep MI, LNM and high-risk of EC (p<0.005). CONCLUSION: MTV and TLG of primary lesions are more valuable in predicting risk stratification of EC patients. Preoperative ¹⁸F-FDG PET/CT imaging is useful in predicting the LNM of EC and may help guide pelvic lymphadenectomy to avoid unnecessary pelvic lymphadenectomy in EC patients with low-risk stratification.
