Cervical cancer, the most common gynecological malignancy, significantly and adversely affects women's physical health and well-being. Traditional surgical interventions and chemotherapy, while potentially effective, often entail serious side effects that have led to an urgent need for novel therapeutic methods. Photothermal therapy (PTT) has emerged as a promising approach due to its ability to minimize damage to healthy tissue. Connecting a biothiol detection group to PTT-sensitive molecules can improve tumor targeting and further minimize potential side effects. In this study, we developed a near-infrared fluorescence (NIRF)/photoacoustic (PA) dual-mode probe, S-NBD, which demonstrated robust PTT performance. This innovative probe is capable of activating NIRF/PA signals to enable the detection of biothiols with high emission wavelength (838 nm) and large Stokes shift (178 nm), allowing for in vivo monitoring of cancer cells. Additionally, the probe achieved an outstanding photothermal conversion efficiency of 67.1%. The application of laser irradiation (660 nm, 1.0 W/cm², 5 min) was able to achieve complete tumor ablation without recurrence. In summary, this seminal study presents a pioneering NIRF/PA dual-mode dicyanoisophorone-based probe for biothiol imaging, incorporating features from PTT for the first time. This pioneering approach achieves the dual objectives of improving tumor diagnosis and treatment.

Objective:To investigate the hepatitis B surface antigen (HBsAg) clearance condition and its predictive factors after treatment with nucleos(t)ide analogues to pegylated interferon-α add-on therapy in patients with chronic hepatitis B.Methods:Patients with chronic hepatitis B who visited the First Affiliated Hospital of Zhengzhou University from 2018~2019 were prospectively enrolled. HBsAg≤ 1500 IU/mL, hepatitis B e antigen-negative, HBV DNA undetectable, received antiviral treatment with nucleos(t)ide analogues for at least one year, and pegylated interferon-α add-on therapy for 48 weeks were included. The primary endpoint of study was to determine the proportion of HBsAg clearance at 72 weeks. Concurrently, the predictive factors for HBsAg clearance were analyzed. Quantitative and qualitative data were analyzed using a t-test or non-parametric test and a Fisher's exact test.Results:A total of 38 cases were included in this study, of which 13 cases obtained HBsAg clearance at 48 weeks of therapy and another six cases obtained HBsAg clearance throughout the extended treatment period of 72 weeks, accounting for 50.00% of all enrolled patients. There was a significant difference in HBsAg dynamics between the HBsAg clearance group and the non-clearance group (P < 0.05). Univariate logistic regression analysis showed that patients' age, baseline, 12-and 24-week HBsAg levels, and early HBsAg reduction were predictive factors for HBsAg clearance at 72 weeks of treatment. Multivariate logistic regression analysis showed that age (OR = 1.311; P = 0.016; 95% confidence interval: 1.051~1.635) and HBsAg levels at 24 weeks of treatment (OR = 4.481; P = 0.004; 95% confidence interval: 1.634~12.290) were independent predictors for HBsAg clearance.Conclusion:Hepatitis B e antigen-negative, nucleos(t)ide analogue treated, HBsAg ≤ 1500 IU/mL, and HBV DNA undetectable, peg-IFNα add-on treatment for 48 weeks could promote HBsAg clearance in patients with chronic hepatitis B. Six of the sixteen cases (37.50%) who did not obtain HBsAg clearance at week 48 did so with the course of therapy extended to week 72. Hence, the optimal individualized treatment strategy should be customized according to the predictors rather than the fixed 48-week course. Age (≤ 38), baseline HBsAg level (≤2.86 log 10IU/ml), HBsAg level at 24 weeks (≤ 0.92 log 10IU/ml), and 12-week HBsAg decrease from baseline (≥ 0.67 log 10IU/ml) indicate that patients are highly likely to obtain HBsAg clearance at the 72 weeks of combination therapy, in which the combined indicator based on HBsAg level ≤0.92 log 10IU/ml at 24 weeks will identify 85.0% to 100.0% of patients with HBsAg clearance.

Objective:To investigate the effect of early gradual diet on reducing delirium in elderly patients with hip arthroplasty.Methods:From January 2018 to January 2020, 74 cases of hip arthroplasty patients aged over 65 years old who were treated in the Third Affiliated Hospital of Sun Yat-sen University were selected as the observation objects. They were randomly divided into experimental group and control group with 37 cases in each group. The experimental group was given early gradual diet on the basis of routine postoperative care, while the control group was given routine postoperative diet on the basis of routine postoperative care. The incidence of postoperative delirium, Pittsburgh Sleep Quality Index (PSQI), patient satisfaction rate, average hospitalization days and average hospitalization expenses were used to evaluate the effect of early gradual diet on reducing delirium in elderly patients with hip arthroplasty.Results:The incidence of delirium in the experimental group was 2.70% (1/37) and 16.22% (6/37) in the control group, the difference was statistically significant ( χ2 value was 3.945, P<0.05); the hospitalization days of the experimental group were (10.68±5.13) d, (13.62±7.19) d in the control group. The difference of hospitalization days was statistically significant ( t value was 2.877, P<0.01). The incidence of difficulty in falling asleep and the satisfaction rate of the experimental group were 8.11% (3/37) and 94.59% (35/37) respectively, and those in the control group were 29.73% (11/37) and 78.38% (29/37) respectively, and the differences were statistically significant ( χ2 value was 5.638, 4.163, P<0.05). Conclusions:Early gradual diet after operation can reduce the incidence of delirium in elderly patients with hip arthroplasty, shorten the average hospitalization days, reduce the incidence of difficulty in falling asleep, improve patients' satisfaction, and help patients to pass through the perioperative period more safely and comfortably.

BACKGROUND: Low dose computed tomography (LDCT) for lung cancer screening is widely employed in China as a result of increasing cancer screening awareness. Although some pulmonary lesions detected by LDCT are cancerous, most of the pulmonary nodules are benign. It is important to make effective preoperative differentiation of pulmonary lesions and to obviate the need for surgery in some patients with benign disease. METHODS: From January 1, 2017 to December 31, 2018, patients in our institution with surgical pathology confirmed benign pulmonary lesions in which malignancy could not be excluded in preoperative assessment were enrolled in this study. Retrospective analysis of clinical data was conducted. RESULTS: 297 cases were collected in this study. Prevalence of benign disease in patients underwent resection for focal pulmonary lesions is 9.8% in our institution. In 197 patients (66.3%), pulmonary lesions were detected by LDCT screening. A total of 323 assessable pulmonary lesions were detected by chest CT. The average diameter of pulmonary lesions was (17.9±12.1) mm, and 91.0% of which were greater than or equal to 8 mm. Solid nodules accounted for 65.6% of these lesions. Imaging characteristics suggesting malignancy were common, including spicule sign (71/323, 22.0%), lobulation (94/323, 29.1%), pleural indentation (81/323, 25.1%), vascular convergence sign (130/323, 40.2%) and vacuole sign (23/323, 7.1%). 292 patients (98.3%) underwent video-assisted thoracoscopic surgery (VATS). Pulmonary wedge resection was performed in 232 cases (78.1%), segmental resection in 13 cases (4.4%) and lobotomy in 51 cases (17.2%). Surgical complications occurred in 4 patients (1.3%). The most frequent findings on surgical pathology analysis were: infectious lesions in 98 cases (33.0%), inflammatory nodules in 96 cases (32.3%), and hamartoma in 64 cases (21.5%). CONCLUSIONS Solid nodules accounted for most of these benign pulmonary lesions in which malignancy could not be excluded preoperatively, and imaging characteristics suggesting malignancy were common. VATS is an important biopsy method to identify etiology and pathology for lesions. The most frequent benign pulmonary diseases that are suspected to be malignant and underwent surgical resection are: infectious lesions, inflammatory nodules and hamartoma.

Objective To investigate the effects of low-dose,sustained release oral theophylline on the chronic obstructive pulmonary disease (COPD) patient.Methods Fifty-six patients with stable COPD were randomly divided into two group:theophylline group (n =35) that was treated with slow-release theophylline(100 mg,twice daily),and control group (n =21) that was given with placebo.A series of parameters including lung function,quality of life scores,body mass index,airflow obstruction,dyspnea,and exercise capacity index (BODE) score,exercise tolerance,exacerbations,satisfaction with treatments and adverse effects were tested before and 12 weeks after the treatments.Results Forty two patients completed the study,25 cases in the slow-release theophylline group,and 17 cases in the placebo group.The differences of two groups before the treatment were not prominent except the age (P ＞ 0.05).After treated with slow-release theophylline,the forced expiratory volume in one second (FEV1),forced vital capacity (FVC) and the symptom score were slightly increased,but there were no statistically significant differences (P ＞0.05).After theophylline therapy,the quality of life score,including activity ability score,disease activity score and total score,and BODE index score were significantly decreased(P ＜0.05),but 6 minutes walk test (6 MWT) differences were no significant (P ＞0.05).The differences in pulmonary function test,the quality of life score,BODE index score and 6 minutes walk test were no significant between before and after the treatment with the placebo (P ＞ 0.05).Compared to the cases who treated with the placebo group,the patients in slow-release theophylline group reduced the frequencies of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) (3/25 vs 7/17,x2 =4.748,P ＜0.05),and increased the efficacy satisfaction (Z =-2.579,P ＜ 0.05).Slightly adverse reaction was observed in 3 cases in slow-release theophylline group,but it could relieve by oneself,and not affect the common treatment.There was no adverse reaction in the placebo group.Conclusions Low dose,sustained release oral theophylline was efficient in improvement of the quality of life scores and BODE index score.
