ObjectiveBased on the theory of "gut-prostate" axis, this study explored the effects and mechanisms of Zishen Tongguan formula and Cinnamomi Cortex in the formula in treating rats with chronic non-bacterial prostatitis(CNP) by detecting the levels of inflammatory factors, and the composition and structure of intestinal flora in CNP rats. MethodsEight out of 42 SD rats were randomly selected as the normal group, and the remaining rats were injected with carrageenan to prepare the CNP model. After successful modeling, 32 rats were randomly divided into the model group, Ningmitai capsule group(0.50 g·kg-1), Zishen Tongguan formula group(2.00 g·kg-1), and the Phellodendri Chinensis Cortex-Anemarrhenae Rhizoma pair group(PCC-AR group, 2.00 g·kg-1), with 8 rats in each group. The administered groups were given the corresponding medicinal solution by gavage, and the normal and model groups were intragastrically administered with an equal volume of normal saline, once a day for 14 consecutive days. The prostate tissues of rats were collected and subjected to hematoxylin-eosin(HE) staining and Masson staining to observe the pathological changes of the tissues in each group. Enzyme-linked immunosorbent assay(ELISA) was used to detect the levels of related inflammatory factors in rat serum, and 16S rDNA sequencing was used to analyze the abundance and diversity changes of gut microbiota before and after administration, and species difference analysis was performed. ResultsAll the administered groups could alleviate the inflammatory symptoms of CNP rats, increase the expression levels of anti-inflammatory factors and decrease the expression levels of pro-inflammatory factors, with the most sIgnificant effect observed in the Zishen Tongguan formula group. Compared with the normal group, the expression levels of interleukin(IL)-8, hypersensitive C-reactive protein(hs-CRP), immunoglobulin(Ig)M, secretory IgA (sIgA), and inducible nitric oxide synthase(iNOS) were sIgnificantly increased in the model group(P<0.01). Compared with the model group, the expression levels of the above inflammatory factors in all administered groups were significantly reduced(P<0.01). When compared with the PCC-AR group, the Zishen Tongguan formula group showed a significant decrease in transforming growth factor(TGF)-β1 expression level(P<0.05) and a significant increase in IgM expression level(P<0.01). The results of gut microbiota analysis showed that, compared with the PCC-AR group, at the order level, the Zishen Tongguan formula group significantly reduced the relative abundance of conditional pathogens such as Bacteroidales, Acidaminococcales, Rhodospirillales, Clostridiales, and Elusimicrobiales(P<0.01). And at the genus level, the Zishen Tongguan formula group significantly decreased the relative abundance of pathogenic microbiota such as Lachnospira and Bacteroides(P<0.01) and significantly increased the relative abundances of beneficial microbiota such as Ruminococcus and Lactobacillus(P<0.01). ConclusionZishen Tongguan formula can reduce the level of harmful intestinal bacteria, increase the level of beneficial intestinal bacteria, down-regulate the expression of serum inflammatory factors, and the small amount of Cinnamomi Cortex in the formula may play a key role in the treatment of CNP with this formula.

Retinal vein occlusion(RVO)is the second most common blinding retinal vascular disease, and its secondary macular edema(ME)is an important cause of visual function impairment in patients. Intravitreal injection of anti-vascular endothelial growth factor(VEGF)drugs serves as the first-line treatment, yet it is confronted with such issues as the need for repeated injections and non-response in some patients. Imaging and laboratory biomarkers play a crucial role in the early accurate diagnosis, prediction of disease progression, and evaluation of visual prognosis of RVO-ME. This study systematically reviews the research progress of imaging and laboratory biomarkers related to the prognosis of RVO-ME after anti-VEGF treatment in recent years, covering imaging biomarkers like central retinal thickness and ellipsoid zone integrity, as well as laboratory biomarkers such as serum APLN and aqueous humor IL-6. It summarizes the associations between different biomarkers and the prognosis of anti-VEGF therapy, aiming to provide a basis for the early accurate assessment and optimization of individualized treatment for RVO-ME patients, which holds significant clinical reference value.

In the field of healthcare service, it is crucial to optimize medical innovation services by combining the preferences of health service providers and demanders (i.e., stakeholders). The best-worst scaling (BWS) method is a recently developed stated preference method for assessing preferences with distinctive advantages. Nevertheless, there is a lack of a comprehensive introduction to stakeholder preference assessment using BWS, thus constraining its applications and promotion. This paper introduces the process of using BWS to assess service providers' preferences for the Shared Medical Appointment for diabetes (SMART), an integrated healthcare service of medicine and health management, in the hope of providing reference for researchers for promoting the use of BWS in implementation research.

Objective:To evaluate the impact of cold-air anesthesia on patients′ comfort and side effects during ablative fractional carbon-dioxide (CO 2) laser treatment for acnescars. Methods:Eighteen patients with atrophic acne scars treated with CO 2 laser were used as split-face comparative study with a cold-air device combined with 5% lidocaine cream on the left side of the face, and the right side as a control group treated with 5% lidocaine cream only. Symptoms and signs of patients were observed during treatment, immediately after treatment, 15 minutes, 30 minutes and 1 month after treatment. The score of patient′s comfort and incidence of adverse events was evaluated. Results:The results were obvious difference between each group. The surface temperature in combined group (33.1±1.3) showed significantly better results compared with other groups (36.9±0.4) during the operative period while the same result after the treatment immediately shown in the combined group (35.1±1.3) compared with other groups (36.4±0.2). The score of erythema shown that combined group (48.7±8.4) was significantly lower than that of the control group (54.8±8.0) ( P<0.05) as the score of exudation in combined group (6.2±1.6) was lower than that in the control group (7.8±1.6). There was significant statistical difference regarding scores of erythema between combined group (46.9±6.6) and control group (51.8±6.9) a month after the treatment. The pigmentation score revealed the same result that the combined group (48.9±8.8) was lower than the other groups (51.4±7.0). No patients had severe adverse events. Conclusions:The cold-air cooling application is safe and effective to reduce the surface temperature, pain and side effects during fractional carbon-dioxide laser treatment.

Objective:To evaluate the effect of hyperthermia on radiation pneumonitis (RP) in elderly patients with esophageal cancer undergoing intensity-modulated radiotherapy (IMRT).Methods:Clinical data of 177 elderly esophageal cancer patients (aged ≥60 years) receiving IMRT in the First Affiliated Hospital of Soochow University and Yixing Cancer Hospital from August 1, 2017 to February 6, 2023 were retrospectively analyzed. Patients were divided into the hyperthermia and non-hyperthermia groups based on whether they received hyperthermia treatment. Patients in two groups received IMRT with 6 MV X-rays. Patients in the hyperthermia group underwent high-frequency hyperthermia within 1 h before radiation using the external thermotherapy device HG-2000Ⅲ (heating temperature: 41-43 ℃ for 40 min, twice a week). After adjusting for confounding factors between two groups using propensity score matching (PSM), the short-term effective rates between two groups were compared using Chi-square test. Univariate analysis and logistic multivariate analysis were employed to compare the incidence of RP between two groups. Results:After applying PSM, 42 pairs were successfully matched, and the baseline data and radiotherapy parameters showed no statistically significant differences between two groups (all P>0.05). The objective response rate (ORR) in the hyperthermia group was significantly higher than that in the non-hyperthermia group (83.3% vs. 64.3%, P=0.047). Univariate analysis revealed that the incidence of RP and symptomatic RP (≥ grade 2) in the hyperthermia group was significantly lower than that in the non-hyperthermia group (61.9% vs. 85.7%, P=0.013; 21.4% vs. 47.6%, P=0.012). Logistic multivariate analysis indicated that hyperthermia was an independent protective factor for symptomatic RP ( P=0.011). Conclusions:The incidence and severity of RP in elderly esophageal cancer patients receiving IMRT can be reduced by hyperthermia. Hyperthermia, as a clinically beneficial green treatment, improves efficacy and reduces toxicity for patients with esophageal cancer.
