Diagnostic whole body scan (Dx-WBS) with 131I and serum Tg level are the main parameters to evaluate the effectiveness of thyroid remnant ablation in patients with DTC.Undetectable Tg and positive radioiodine uptake in the thyroid bed (Tg-/Dx-WBS+) may be found in some patients.However,the clinical significance is uncertain.A small amount of thyroidal remnant,a small DTC lesion,increased expression of NIS gene and autoimmune inflammation may all result in Tg-/Dx-WBS+.A wait-and-watch approach without rushing for high-dose radioiodine treatment might be a more reasonable approach for these patients.

AIM To establish an HPLC method for the simultaneous content determination of five constituents in Jiangzhi Granules (Salviae miltiorrhizae Radix et Rhizoma,Polygoni cuspidati Rhizoma et Radix,Artemisiae scopariae Herba,etc.).METHODS The analysis of methanol extract of this drug was performed on a 30 ℃ thermostatic Hanbon-C18 column (4.6 mm × 250 mm,5 μm),with the mobile phase comprising of acetonitrile (A) 0.1％ phosphoric acid (B) flowing at 1.0 mL/min in a gradient elution manner,and the detection wavelengths were set at 286 nm (0-30,40-50 min) and 203 nm (30-40 min).RESULTS Gypenoside A,chlorogenic acid,polydatin,salvianolic acid B and emodin showed good linear relationships within the ranges of 0.176-2.46,0.056-0.84,0.36-5.40,0.192-2.88 and 0.12-1.80 μg (r ＞0.999 0),respectively,whose average recoveries were 97.17％-102.59％ with the RSDs of 1.9％-2.9％.CONCLUSION This accurate and simple method can be used for the quality control of Jiangzhi Granules.

Objective: To explore the cognitive level and the mental status of the patients suffering from perimenopausal syndrome in Shanghai, and to identify the traditional Chinese medicine syndrome distribution feature of perimenopausal syndrome. Methods: The cognitive level of the perimenopausal women was evaluated by using general living problem questionnaire. The mental status of the perimenopausal women was evaluated by using self-rating depressive scale. The traditional Chinese medicine syndrome distribution feature of perimenopausal syndrome was identified by using traditional Chinese medical symptoms questionnaire. Results: A total of 634 perimenopausal women finished the investigation. There were 74.76% (474/634) patients who knew little about the perimenopausal syndrome; 77.29% (490/634) patients had a depressive tendency; 8.36% (53/634) patients had depressive disorder. There were 72.40% (459/634) patients who had the symptoms such as susceptibility to anger and restlessness, restless sleep at night, thirst with dry throat and bitter taste, and all these symptoms could be classified into hyperactivity of heart and liver fire syndrome. Conclusion: Patients suffering from perimenopausal syndrome know little about this disease and mostly have depressive tendency, and the major traditional Chinese medicine syndrome pattern is hyperactivity of heart and liver fire based on the chief clinical manifestations of the patients.

Objective To examine the validity and reliability of the Chinese version of ambivalence over emotional expression questionnaire(AEQ) in breast cancer survivors.Methods A total of 323 breast cancer survivors were divided into 2 parts:sample 1 contains 122 breast cancer survivors for item and exploratory factor analysis,while sample 2 contains 201 breast cancer survivors for further confirmatory factor analysis,criterion validity,and internal consistency reliability.Results One-factor construct was determined and the results of confirmatory factor analysis showed that one-factor construct AEQ had a good construct validity (x2/df=1.01,CFI=0.99,TLI=0.99,NFI=0.86,IFI=0.99,RMSEA=0.02).The AEQ score was correlated with TAS-20 (r=0.28,P＜0.01).Cronbach α coefficient,Spearman-Brown split coefficient and the test-retest reliability of AEQ were 0.86,0.80 and 0.79,respectively.Conclusion The AEQ is a reliable tool to assess the ambivalence over emotional expression in Chinese breast cancer survivors.

Objective: To explore the psychological vulnerability in the relationship between stressful life events and psychological crisis, and to provide basis for psychological crisis prevention among college students. Methods: With stratified cluster sampling，3584 students in Weifang Medical University and Weifang University were selected for a crosssectional selfadministrated questionnaire survey in December 2017. A selfdesigned general questionnaire, Adolescent SelfRating Life Events Check List(ASLEC), psychological vulnerability scale, and psychological crisis performance questionnaire for college students were applied in the survey. Mediating effect was tested by using SPSS 23.0 and AMOS 23.0. Results: The average score was 36.53±8.58 for life events(ASLEC), 54.21±11.80 for psychological vulnerability,and 26.33±39.72 for psychological crisis performance. The life events score was positively correlated with psychological crisis score (r=0.54, P<0.05) and positively correlated with psychological vulnerability score(r=0.30, P<0.05); psychological vulnerability score was positively correlated with psychological crisis score(r=0.37, P<0.05). Psychological vulnerability played a partial intermediary role on the relationship between life events and psychological among undergraduates,the effect was 0.10 accounting for 15.13% of the total effect. Conclusion Life events have made a direct influence and an indirect influence mediated by psychological crisis vulnerability on psychological crisis among undergraduates.

Objective:To compare the hemostatic effects and patient comfort of different compression methods for hemostasis after transradial coronary intervention.Methods:A total of 160 patients who received transradial coronary intervention in The Affiliated Hospital of Hangzhou Normal University from October 2018 to February 2020 were included in this study. In group A ( n = 80), patients underwent spiral compression at the puncture point (release for 1 turn at 2 hours after surgery, rotation for 1 circle after 1 hour, and full decompression). In group B ( n = 80), patients underwent spiral compression at the puncture point (release for 1 turn at 2 hours after surgery, rotation for 1 circle after 2 hours, and full decompression). Percutaneous arterial oxygen saturation value in the affected limb, heart rate, and Visual Analog Scale score at different times after surgery, pain and comfort score at 2 and 12 hours post-surgery were compared between the two groups. Results:Percutaneous arterial oxygen saturation value at 4 and 12 hours post-surgery in group A was (96.6 ± 0.7)% and (97.8 ± 0.5)%, respectively, which was significantly higher than that in group B [(96.2 ± 0.6)%, (97.6 ± 0.7)%, t = 3.88, 2.08, both P < 0.05]. There were no significant differences in total score and subscale score of the General Comfort Questionnaire at 2 hours post-surgery between groups A and B (both P < 0.05). At 12 hours post-surgery, scores of psychological and physical subscales and total score of the General Comfort Questionnaire in group A were (23.64 ± 3.02) points, (12.64 ± 2.05) points, (68.25 ± 6.04) points, which were significantly higher than those in group B [(22.20 ± 2.96) points, (11.38 ± 2.47) points, (64.42 ± 6.71) points, t = 3.05, 3.51, 3.79, all P < 0.05]. At 2 hours post-surgery, there was no significant difference in Numerical Rating Scale score between groups A and B ( P > 0.05). At 4 and 12 hours post-surgery, Numerical Rating Scale score in group A was (2.51 ± 0.58) points and (1.75 ± 0.76) points, respectively, which was significantly lower than that in group B [(2.95 ± 0.63) points, (2.31 ± 0.71) points, t = -4.59, -4.82, both P < 0.05). The incidence of complications was significantly lower in group A than in group B (8.75% vs. 20.00%, χ2 = 4.11, P < 0.05). Conclusion:Compression for hemostasis is highly effective by releasing for 1 turn at 2 hours after transradial coronary intervention, rotating for 1 circle after 1 hour, and full compression because it can greatly mitigate pain, ensure the oxygen supply to the affected limbs, and improve patient comfort.

Objective:To investigate the effect of five-element music therapy combined with meridian-based acupoint massage timed according to qi circulationon on negative emotions and sleep quality in older adults with chronic heart failure. Methods:A total of 112 older adult patients with chronic heart failure who received treatment at The Affiliated Hospital of Hangzhou Normal University between January 2022 and June 2023 were included in this study. They were randomly divided into a control group ( n = 56) and a study group ( n = 56) using the random number table method. Based on conventional treatment, the control group received five-element music therapy, while the intervention group underwent a combination of five-element music therapy and meridian-based acupoint massage timed according to qi circulation. Before and after the intervention, a comparison was made between the two groups in terms of the scores of the Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD), Pittsburgh Sleep Quality Index (PSQI), and various dimensions of the Minnesota Living with Heart Failure Questionnaire (MLHFQ). Additionally, the sleep outcome and patient satisfaction were also compared between the two groups. Results:After intervention, the scores of the HAMA and HAMD in the study group were (11.29 ± 2.48) points and (12.48 ± 3.36) points, respectively. In contrast, the control group had scores of (15.93 ± 3.35) points and (16.50 ± 4.32) points, respectively. After intervention, the scores of the HAMA and HAMD scales in both the study and control groups demonstrated a significant reduction in comparison with their respective pre-intervention scores [study group: (20.13 ± 5.18) points, (23.95 ± 8.97) points, control group: (19.36 ± 5.45) points, (23.79 ± 7.61) points, t = 15.35, 10.24, 5.65, 8.93, all P < 0.001). After intervention, the scores of the HAMA and HAMD scales in the study group were significantly lower than those in the control group ( t = -8.34, -5.49, both P < 0.001). After intervention, the scores of the PSQI in the study and control groups were (7.05 ± 0.96) points and (9.91 ± 1.28) points, respectively. After intervention, the scores of PSQI in both the study and control groups demonstrated a significant reduction compared with their respective pre-intervention scores [study group: (12.98 ± 2.21) points, control group: (12.50 ± 2.48) points, t = 24.68, 9.79, both P < 0.05]. After intervention, the score of the PSQI in the study group was significantly lower than that in the control group ( t = 13.34, P < 0.05). Based on the scores across various dimensions of the MLHFQ, it was observed that after intervention, the scores of emotional, physical, and other domains in both the study and control groups [study group: (9.36 ± 2.29) points, (16.95 ± 3.80) points, (18.50 ± 2.33) points; control group: (12.93 ± 2.00) points, (19.98 ± 3.98) points, (20.04 ± 2.24) points] decreased significantly compared with their pre-intervention scores [study group: (15.57 ± 1.55) points, (26.23 ± 4.63) points, (21.18 ± 2.50) points, control group: (16.09 ± 1.87) points, (25.32 ± 4.40) points, (21.57 ± 2.69) points, t = 21.66, 18.55, 8.44, 11.29, 11.73, 4.61, all P < 0.001]. After intervention, the scores of emotional, physical, and other domains in the study group were significantly lower than those in the control group ( t = -8.79, -4.13, -3.56, all P < 0.05). Patient satisfaction in the study group was superior to that that in the control group [98.21% (55/56) vs. 87.50% (49/56), χ2 = -3.09, P < 0.05]. Total effective rate of intervention on sleep in the study group was significantly higher than that in the control group [92.86% (52/56) vs. 78.57% (44/56), χ2 = -2.09, P < 0.05]. Conclusion:Five-element music therapy combined with meridian-based acupoint massage timed according to qi circulationon in the treatment of chronic heart failure in older adults can effectively alleviate negative emotions, improve the quality of life and sleep, and increase patient satisfaction with nursing care.

Objective:To explore the value of machine learning models based on multiple structural MRI features for diagnosis of Parkinson disease (PD).Methods:The clinical and imaging data of 60 PD patients (PD group) diagnosed in the Neurology Department of the Second Affiliated Hospital of Soochow University from November 2017 to August 2019 and 56 normal elderly people (NC group) recruited from the community were retrospectively analyzed. All subjects underwent brain MR imaging. Multiple structural MRI features were extracted from cerebellum, deep nuclei and of brain cortex based on different partition templates. The Mann-Whitney U test, as well as least absolute shrinkage and selection operator regression were used to select the most discriminating features. Finally, logistic regression (LR) and linear discriminant analysis (LDA) classifier combined with the 5-fold cross-validation scheme were used to construct the models based on structural features of cerebellum, deep nuclei and cortex, and a combined model based on all features. The receiver operating characteristic curves were drawn, and the diagnostic performance and clinical net benefit of each model were evaluated by the area under curve (AUC) and the decision curve analysis (DCA). Results:In total, four cerebellum (asymmetry index of Lobule Ⅵ volume, asymmetry index of Lobule ⅦB cortical thickness, asymmetry index of total gray matter volume and absolute value of right Lobule Ⅵ gray matter volume), 3 deep nuclei (absolute value of right nucleus accumbens volume, absolute and relative value of total nucleus accumbens volume) and 3 cortex features (local gyration index of left PFm, local fractal dimension of right superior frontal gyrus and sulcal depth of left superior occipital gyrus) were selected as the most discriminating features, and the related models were constructed. In validation set, the AUC of cerebellum, deep nuclei, cortex and combined models for diagnosis of PD based on LR classifier were 0.692, 0.641, 0.747 and 0.816; the AUC of cerebellum, deep nuclei, cortex and combined models for diagnosis of PD based on LDA classifier were 0.726, 0.610, 0.752 and 0.818. The diagnostic efficiency of the combined models based on LR and LDA classifiers were significantly better than those of other models ( P<0.05). The DCA curve demonstrated that the combined models based on LR and LDA classifiers showed the highest clinical net benefit. Conclusion:The combined models with all structural features of cerebellum, deep nuclei and cortex included based on LR and LDA classifiers showed favorable performance and clinical net benefit for diagnosis of PD, which have the potential application value in clinical diagnosis.

ObjectiveTo compare the efficacy and safety of acupuncture combined with auricular acupoints patches and nicotine transdermal patch in treating moderate to severe nicotine dependence. MethodsIn a rando-mized controlled trial， 64 quit smoking voluntary subjects with moderate to severe nicotine dependence were randomly divided at a ratio of 1∶1 into a treatment group and a control group， with 32 cases in each group. The treatment group was given acupuncture combined with auricular acupoints patches， twice weekly， four weeks as a course for two courses. The control group was given nicotine transdermal patch， one patch per day for 24 hours， 8 weeks. The cure rate was assessed after treatment and at follow-up （the 16th week after treatment）.The daily smoking volume， exhaled carbon monoxide （CO） value， Nicotine Dependence Scale （FTND）， Minnesota Nicotine Withdrawal Symptoms Scale （MNWS）， and Pittsburgh Sleepiness Index Inventory （PSQI） were evaluated before and after treatment and at follow-up， and adverse effects were recorded. ResultsIn terms of the cure rate， there were both six cured cases （20%） after treatment and at follow-up in the treatment group， while in the control group， seven （23.3%） and five （16.7%） patients were cured after treatment and at follow-up， respectively， with no statistically significant differences between the two groups both after treatment and at follow-up （P＞0.05）. The daily smoking volume and exhaled CO value significantly decreased after treatment and at follow-up in both groups （P＜0.05）， but were not significantly different between the groups after treatment and at follow-up （P＞0.05）. After treatment and at follow-up， FTND， MNWS， and PSQI scores were significantly reduced in both groups compared with those before treatment （P＜0.05）. There was no statistically significant difference in the FTND scale scores between the two groups after treatment and at follow-up （P＞0.05）， while the MNWS and PSQI scale scores were lower in the treatment group than in the control group （P＜0.05）. ConclusionAcupuncture combined with auricular acupoint patches for moderate to severe nicotine dependence has comparable effect with the first-line drug nicotine patch in terms of increasing the cure rate and decreasing the degree of nicotine dependence， and is superior to nicotine patch in terms of relieving withdrawal symptoms and improving sleep， with stable long-term effect.
