Objective:To translate the Illness Identity Questionnaire (IIQ) into Chinese and test its reliability and validity.Methods:The English version of IIQ was translated into Chinese and back-translated according to the Brislin model. The item of the Chinese version was determined after cross-cultural adaptation and pre-experiment. A total of 368 patients with IBD treated in the First Affiliated Hospital with Nanjing Medical University from September 2022 to March 2023 were selected for a questionnaire survey to evaluate the reliability and validity of the questionnaire.Results:The Chinese version of IIQ contained 24 items in four dimensions. Four common factors were extracted by exploratory factor analysis, and the cumulative variance contribution rate was 64.025%. Confirmatory factor analysis showed that each fitting index of the modified model was within the acceptable range. The Cronbach's α coefficients of rejection, acceptance, engulfing, and enrichment in Chinese IIQ were respectively 0.780, 0.800, 0.921, and 0.917. The split-half reliability coefficients were 0.824, 0.818, 0.943, and 0.929; the retest reliability coefficients were 0.695, 0.667, 0.725, and 0.572, respectively.Conclusions:The Chinese version of IIQ is reliable and valid and can be used to assess illness identity in patients with chronic diseases.

After undergoing the long-term lived experience of symptoms and suffering, chronic patients change the understanding of self and try to create or regain a coherent sense of self, resulting in different degrees of illness identity. This research reviewed the origin, connotation, assessment tools, and summarized the performance level, influencing factors and intervention studies of illness identity in patients with chronic disease. It would provide references for research of illness identity, and to provide new ideas for promoting patients with chronic diseases to cope with and manage diseases.

Objective: To investigate the incidence and risk factors of systemic allergic reactions induced by subcutaneous immunotherapy (SCIT) in patients undergoing SCIT injections in Peking Union Medical College Hospital (PUMCH). Methods: This is a single center retrospective cohort study. Using the outpatient information system of PUMCH, the demographic information and injection-related reaction data of patients undergoing SCIT injection in Allergy Department of PUMCH from December 2018 to December 2022 were retrospectively analyzed to count the incidence and risk factors of systemic allergic reactions caused by SCIT. Mann-Whitney nonparametric test or chi-square test was used for single-factor analysis, and multiple logistic regression was used for multiple-factor analysis. Results: A total of 2 897 patients received 18 070 SCIT injections in Allergy Department during the four years, and 40 systemic allergic reactions occurred, with the overall incidence rate of 0.22%. The incidence of systemic allergic reaction was 0.37% when using imported dust mite preparation and 0.15% when using domestic multi-component allergen preparation. The risk factors significantly related with SCIT-induced systemic allergic reactions in patients using imported dust mite preparation were age less than 18 years old (OR=3.186,95%CI: 1.255-8.085), highest injection concentration (OR value could not be calculated because all patients with systemic reactions were injected with highest concentration), and large local reaction in previous injection (OR=22.264,95%CI: 8.205-60.411). The risk factors for SCIT-induced systemic allergic reactions in patients using domestic allergen preparation were 5 or more types of allergens (OR=3.455,95%CI: 1.147-10.402), highest injection concentration (OR=3.794,95%CI: 1.226-11.740) and large local reaction in previous injection (OR=63.577,95%CI: 22.248-181.683). However, SCIT injection in pollen allergic patients during the pollen season did not show a correlation with systemic allergic reaction. Conclusion: The incidence of SCIT-induced systemic allergic reactions was low in the Chinese patient population of this study. Patients with one or more risk factors, such as multiple allergen injection, highest injection concentration, large local reaction in previous injection, should be given high attention and vigilance against systemic allergic reactions.

Objective: Recent studies have highlighted the active and potential role of perivascular adipose tissue (PVAT) in atherosclerosis and aneurysm progression, respectively. This study explored the link between PVAT attenuation and abdominal aortic aneurysm (AAA) progression using computed tomography angiography (CTA). Materials and Methods: This multicenter retrospective study analyzed patients with AAA who underwent CTA at baseline and follow-up between March 2015 and July 2022. The following parameters were obtained: maximum diameter and total volume of the AAA, presence or absence of intraluminal thrombus (ILT), maximum diameter and volume of the ILT, and PVAT attenuation of the aortic aneurysm at baseline CTA. PVAT attenuation was divided into high (> -73.4 Hounsfield units [HU]) and low (≤ -73.4 HU). Patients who had or did not have AAA progression during the follow-up, defined as an increase in the aneurysm volume > 10 mL from baseline, were identified. Kaplan–Meier and multivariable Cox regression analyses were used to investigate the association between PVAT attenuation and AAA progression. Results: Our study included 167 participants (148 males; median age: 70.0 years; interquartile range: 63.0–76.0 years), of which 145 (86.8%) were diagnosed with AAA accompanied by ILT. Over a median period of 11.3 months (range: 6.0–85.0 months), AAA progression was observed in 67 patients (40.1%). Multivariable Cox regression analysis indicated that high baseline PVAT attenuation (adjusted hazard ratio [aHR] = 2.23; 95% confidence interval [CI], 1.16–4.32; P = 0.017) was independently associated with AAA progression. This association was demonstrated within the patients of AAA with ILT subcohort, where a high baseline PVAT attenuation (aHR = 2.23; 95% CI, 1.08–4.60; P = 0.030) was consistently independently associated with AAA progression. Conclusion Elevated PVAT attenuation is independently associated with AAA progression, including patients of AAA with ILT, suggesting the potential of PVAT attenuation as a predictive imaging marker for AAA expansion.

The 3-succinate-30-stearyl glycyrrhetinic acid(18-GA-Suc) was inserted into glycyrrhetinic acid(GA)-tanshinone Ⅱ_A(TSN)-salvianolic acid B(Sal B) liposome(GTS-lip) to prepare liver targeting compound liposome(Suc-GTS-lip) mediated by GA receptors. Next, pharmacokinetics and tissue distribution of Suc-GTS-lip and GTS-lip were compared by UPLC, and in vivo imaging tracking of Suc-GTS-lip was conducted. The authors investigated the effect of Suc-GTS-lip on the proliferation inhibition of hepatic stellate cells(HSC) and explored their molecular mechanism of improving liver fibrosis. Pharmacokinetic results showed that the AUC_(Sal B) decreased from(636.06±27.73) μg·h·mL~(-1) to(550.39±12.34) μg·h·mL~(-1), and the AUC_(TSN) decreased from(1.08±0.72) μg·h·mL~(-1) to(0.65±0.04) μg·h·mL~(-1), but the AUC_(GA) increased from(43.64±3.10) μg·h·mL~(-1) to(96.21±3.75) μg·h·mL~(-1). The results of tissue distribution showed that the AUC_(Sal B) and C_(max) of Sal B in the liver of the Suc-GTS-lip group were 10.21 and 4.44 times those of the GTS-lip group, respectively. The liver targeting efficiency of Sal B, TSN, and GA in the Suc-GTS-lip group was 40.66%, 3.06%, and 22.08%, respectively. In vivo imaging studies showed that the modified liposomes tended to accumulate in the liver. MTT results showed that Suc-GTS-lip could significantly inhibit the proliferation of HSC, and RT-PCR results showed that the expression of MMP-1 was significantly increased in all groups, but that of TIMP-1 and TIMP-2 was significantly decreased. The mRNA expressions of collagen-I and collagen-Ⅲ were significantly decreased in all groups. The experimental results showed that Suc-GTS-lip had liver targeting, and it could inhibit the proliferation of HSC and induce their apoptosis, which provided the experimental basis for the targeted treatment of liver fibrosis by Suc-GTS-lip.

OBJECTIVE: To explore the effects of ultrasound-guided stellate ganglion block (SGB) on perioperative stress response, gastrointestinal hormones and postoperative gastrointestinal function recovery in patients undergoing laparoscopic radical gastrectomy for gastric cancer. METHODS: This study was conducted among 60 American Society of Anesthesiologists (ASA) class II-III patients with gastric cancer (regardless of gender, aged 35-75 years with BMI of 18.5-26 kg/m²) undergoing elective laparoscopic radical gastrectomy. The patients were randomized into experimental group (S group, n=30) and control group (NS group, n=30). In S group, SGB at the C₆ level of the right cervical spine was performed under ultrasound guidance 15 min before induction of anesthesia by injection of 7 mL 0.5% ropivacaine; the patients in NS group received injections of normal saline in the same manner. Peripheral venous blood samples were collected before SGB (T1), after surgery (T2), and on the 2nd and 6th days after surgery (T3 and T4) for determination of the levels of motitin (MOT), vasoactive intestinal peptide (VIP), cortisol (COR), and blood glucose (GLU). Intraoperative usage of sufentanil, recovery rate of intestinal sounds at 36, 48, 60, 72, 84 and 96 h after operation and the time of first passage of flatus were recorded and compared between the two groups. RESULTS: There was no significant difference in the total amount of sufentanil consumption between the two groups. Compared with those in NS group, the patients in S group had significant lower COR and VIP levels (P < 0.05) and higher MOT level (P < 0.05) at T2, T3 and T4. Glu level at T2 and T3 was also significantly lower in S group (P < 0.05). The recovery rates of intestinal sounds at 36, 48, 60, 72 and 84 h after surgery were significantly higher (P < 0.05) and the time of the first passage of flatus was earlier in S group than in NS group (P < 0.05). CONCLUSION In patients with gastric cancer undergoing laparoscopic radical gastrectomy, ultrasound-guided SGB can reduce postoperative stress level, promote the recovery of gastrointestinal hormone secretion, and accelerate postoperative recovery of gastrointestinal functions.

This study aimed to investigate the effect of Tibetan medicine Ershiwuwei Songshi Pills(ESP) on the intestinal flora of non-alcoholic steatohepatitis(NASH) mice. Forty-eight male C57 BL/6 mice were randomly divided into the control group, model(methionine-choline-deficient, MCD) group, high-(0.8 g·kg~(-1)), medium-(0.4 g·kg~(-1)), and low-dose(0.2 g·kg~(-1)) ESP groups, and pioglitazone(PGZ, 10 mg·kg~(-1)) group, with eight mice in each group. Mice in the control group were fed with normal diet, while those in the remaining five groups with MCD diet for five weeks for inducing NASH. During modeling, they were gavaged with the corresponding drugs. The changes in body mass, daily water intake, and daily food intake were recorded. At the end of the experiment, the liver tissues were collected and stained with hematoxylin-eosin(HE) for observing the pathological changes, followed by oil red O staining for observing fat accumulation in the liver. The levels of serum aspartate aminotransferase(AST) and alanine aminotransferase(ALT) and triglyceride(TG) in liver tissue were measured. The changes in intestinal flora of mice were determined using 16 S rRNA high-throughput sequencing technology. The results showed that compared with the model group, the high-, medium-and low-dose ESP groups and the PGZ group exhibited significantly lowered AST and ALT in serum and TG in liver tissues and alleviated hepatocellular steatosis and fat accumulation in the liver. As demonstrated by 16 S rRNA sequencing, the abundance index and diversity of intestinal flora decreased in the model group, while those increased in the ESP groups. Besides, the Firmicutes to Bacteroidetes ratio decreased at the phylum level. In the alteration of the composition of intestinal flora, ESP reduced the abundance of Erysipelotrichia and Faecalibaculum but increased the abundance of Desulfovibrionaceae, Rikenellaceae, Lachnospiraceae, and Ruminococcaceae. This study has revealed that ESP has a protective effect against NASH induced by MCD diet, which may be related to its regulation of the changes in intestinal flora, alteration of the composition of intestinal flora, and inhibition of the intestinal dysbiosis.
