Objective To study the effects of cognitive behavioral therapy(CBT)on nutritional status and postoperative recovery in patients after gastric cancer surgery.Methods Sixty patients diagnosed with gastric cancer between January 1,2023,and December 30,2023,at the hospital in the department of gastroin-testinal and gland surgery were included in this study.Patients were randomly divided by drawing lots into ei-ther the observation group(received routine care plus CBT—based nursing program)or the control group(received routine care),with 30 patients in each group.Nutritional indicators and postoperative recovery out-comes were compared between the two groups.Results After the intervention,patients in the observation group showed significantly higher levels of albumin and hemoglobin compared to the control group(P＜0.05).However,there was no statistically significant difference in prealbumin levels between the two groups(P＞0.05).Furthermore,patients in the observation group scored higher on the Quality of Recovery-40 scale in terms of emotional state,physical comfort,psychological support,and overall score compared to the control group(P＜0.05).After the intervention,the observation group showed significantly lower HADS scores com-pared to the control group,with a statistically significant difference(P＜0.05).Conclusion CBT demon-strates significant positive effects in improving nutritional status and postoperative recovery quality in gastric cancer patients.CBT improves patients'emotional state,thereby affecting appetite and nutritional status,and promotes postoperative physical function recovery.

Objective To explore the mechanism of Huoxiang Zhengqi Dropping Pills in treating dampness encumbering the spleen and stomach type rats by metabolomics method based on gas chromatography-time of flight mass spectrometry(GC-TOF/MS).Methods Male SD rats were randomly divided into normal group,model group and Huoxiang Zhengqi Dropping Pills group(1 g·kg-1).The rat model of dampness encumbering the spleen and stomach was prepared by comprehensive physical modeling method combined with improper diet.Intragastric administration was performed once a day for 10 consecutive days.The macroscopic signs and behavioral indexes(body mass,body length,tail length,abdominal circumference index and spontaneous activities frequency)of rats were observed.GC-TOF/MS method was used to analyze the serum and urine metabolome of rats,identify potential biomarkers related to dampness encumbering the spleen and stomach,and analyze the metabolic pathway of Huoxiang Zhengqi Dropping Pills in rats with dampness encumbering the spleen and stomach.Results Compared with the normal group,the body mass,body length,tail length and spontaneous activities frequency of the rats in the model group were significantly reduced(P＜0.05),and the abdominal circumference index was significantly increased(P＜0.05).Compared with the model group,the body mass,body length and spontaneous activities frequency of the rats in the Huoxiang Zhengqi Dropping Pills group were significantly increased(P＜0.05),and the abdominal circumference index was significantly decreased(P＜0.05).A total of 38 and 44 potential biomarkers related to dampness encumbering the spleen and stomach were identified in rat serum and urine,respectively.Huoxiang Zhengqi Dropping Pills can effectively interfere with the serum and urine metabolic phenotypes of model rats,and can significantly reverse 17 and 13 potential biomarkers in serum and urine,involving a total of 7 metabolic pathways.Conclusion The intervention mechanism of Huoxiang Zhengqi Dropping Pills on rats with dampness encumbering the spleen and stomach syndrome may be related to the regulation of tryptophan metabolism,histidine metabolism,glutamate-glutamine metabolism,energy metabolism and intestinal flora.

Objective:To investigate the impacts of antenatal anxiety on preterm birth and low birth weight.Methods:Women in early pregnancy were recruited for follow-up, antenatal anxiety in three trimesters was screened using Self-Rating Anxiety Scale and the score ≥50 was regarded as anxiety. Logistic regression analysis was conducted to evaluate the associations of the anxiety in three trimesters, new onset anxiety in the second and third trimesters with infant birth outcomes, such as preterm birth and low birth weight.Results:The rates of anxiety in the first, second and third trimesters of pregnancy were 12.5%, 3.7%, and 7.4% respectively. We found that there was no statistical association between anxiety in the first and second trimester and preterm birth. The anxiety in the third trimester was associated with increased odds for preterm birth ( OR=3.55, 95 %CI: 1.62-7.82). Associations between anxiety in all three trimesters and low birth weight were not significant. New onset anxiety in the third trimester was associated with significant increased risk of premature delivery ( OR=5.20, 95 %CI: 1.84-14.70) and low birth weight ( OR=6.93, 95 %CI: 2.42-19.88). Conclusions:Our study showed that anxiety in the third trimester is an important risk factor for premature delivery, new onset anxiety symptoms in the third trimester can significantly increase the incidence of premature birth and low birth weight of infant.
