OBJECTIVE To investigate ameliorative effects and mechanisms of two probiotics （Bacillus subtilis， Lactobacillus acidophilus） combined with Aurantii Fructus Immaturus （AFI） on functional dyspepsia （FD） in rats. METHODS Rats were randomly divided into blank group， model group， positive control group （domperidone group， 2.7 mg/kg）， AFI group （9 g/kg）， L. acidophilus group （5×107 cfu/kg）， B. subtilis group （5×107 cfu/kg）， L. acidophilus+ AFI group （L. acidophilus 5×107 cfu/kg+ AFI 9 g/kg）， and B. subtilis+AFI group （B. subtilis 5×107 cfu/kg+AFI 9 g/kg）， with 8 rats in each group. Except for the blank group， FD model was established by tail-clamping stimulation+hunger and satiety disorder+swimming exhaustion in other groups. After modeling， each group was given the corresponding drug/probiotic suspensions/physiological saline intragastrically， once a day， for 14 consecutive days. After the last medication， gastric emptying rate and the rate of propulsion of the small intestine in rats were measured； the levels of brain-gut peptide-related indicators [gastrin （GAS）， substance P （SP）， vasoactive intestinal peptide （VIP）， somatostatin （SS） and cholecystokinin （CCK）] in the serum of rats were measured. The pathological morphology of the gastric antrum tissue and duodenal tissue was observed. Cecal contents from the rats were collected for gut microbiota sequencing analysis. The protein expression levels of tyrosine kinase receptor c-Kit and stem cell factor （SCF） in the gastric antrum tissue， as well as Toll-like receptor 4 （TLR4）， myeloid differentiation factor 88 （MyD88）， and nuclear factor κB （NF-κB） in the duodenal tissue of the rats were detected. RESULTS Compared with the blank group， model group showed significantly lower gastric emptying rate， small intestinal propulsion rate， serum levels of GAS and SP， relative abundance of Firmicutes， Ace， Chao and Sobs indexes of the gut microbiota， and protein levels of SCF and c-Kit in gastric antrum （P＜0.05）， while serum levels of VIP， SS and CCK， relative abundance of Bacteroidetes， as well as protein expressions of TLR4， MyD88， and NF-κB， were significantly higher （P＜0.05）. The histological structure JZYC23S53） of the gastric antrum tissue appeared basically normal； however， abnormalities were observed in the duodenal structure， with a significant infiltration of inflammatory cells visible. Compared with the model group， all treatment groups significantly modulated most of the above indexes （P＜0.05）. The histological structure of the gastric antrum tissue was normal. Except for the B. subtilis group and the B. subtilis+AFI group， the pathological states of the duodenum in the remaining rats gradually recovered. Compared with each single drug group， most of above indexes in rats from each combination group showed further improvement （P＜0.05）. CONCLUSIONS The combination of AFI with two probiotics can improve gastrointestinal motility in FD rats， and the effect is superior to that of using the drugs alone. The specific underlying mechanisms may be related to the activation of the SCF/c-Kit signaling pathway and the inhibition of the TLR4/MyD88/NF-κB signaling pathway.

Objective: To investigate the Alzheimer's disease (AD) influencing factors among the elderly, so as to provide a basis for early prevention and intervention. Methods: From March to June 2024, participants aged 60 years and above from a sub-district in Haishu District, Ningbo City, Zhejiang Province were selected using a convenience sampling method. Data on demographics, lifestyle, and health status were collected through questionnaire surveys. Depressive symptoms were evaluated using the short-form Geriatric Depression Scale. The Chinese Mini-Mental State Examination (MMSE) was used for the initial screening of AD, and individuals who screened positive were further diagnosed by psychiatrists. Factors affecting AD among the elderly were analyzed using a multivariable logistic regression model. Results: A total of 3 644 individuals were surveyed, comprising 1 526 males (41.88%) and 2 118 females (58.12%). The mean age was (71.85±7.44) years. AD was detected in 200 cases, with a detection rate of 5.49%. Multivariable logistic regression analysis showed that individuals aged ≥65 years (65-<70 years, OR=3.012, 95%CI: 1.007-9.012; 70-<75 years, OR=3.131, 95%CI: 1.059-9.260; 75-<80 years, OR=5.779, 95%CI: 1.989-16.784; ≥80 years, OR=16.810, 95%CI: 5.926-47.685), those who were unmarried, divorced, or widowed (OR=1.973, 95%CI: 1.383-2.815), those with hearing loss (OR=1.573, 95%CI: 1.128-2.193), those with diabetes mellitus (OR=1.958, 95%CI: 1.362-2.814), and those with depressive symptoms (OR=4.143, 95%CI: 2.997-5.728) had a higher risk of AD. Conversely, individuals with an educational level of primary school or above (primary school, OR=0.579, 95%CI: 0.401-0.835; junior high school or above, OR=0.438, 95%CI: 0.259-0.741), and those who engaged in regular physical exercise (OR=0.414, 95%CI: 0.264-0.649) had a lower risk of AD. Conclusions The detection rate of AD was relatively high among the elderly in Haishu District. AD among the elderly was related to age, educational level, marital status, physical exercise, hearing loss, diabetes mellitus, and depressive symptoms.

OBJECTIVE: To observe the clinical efficacy of acupuncture combined with bamboo-based medicinal moxibustion in the treatment of chronic insomnia complicated with mild depressive state. METHODS: A total of 60 patients with chronic insomnia complicated with mild depressive state were randomly divided into an observation group and a control group, 30 cases in each group. The control group was treated with acupuncture at bilateral Zhaohai (KI6), Shenmen (HT7), Sanyinjiao (SP6), Anmian (Extra) and Sishencong (EX-HN1), Baihui (GV20), etc. The observation group was treated with bamboo-based medicinal moxibustion based on the treatment in the control group, on the abdomen，Shenque (CV8), Guanyuan (CV4), Zhongwan (CV12) and bilateral Tianshu (ST25) were selected , on the back, the acupoints of governer vessel from Dazhui (GV14) to Yaoshu (GV2) were selected. Both groups were treated once every other day, 3 times a week for 4 weeks. The Pittsburgh sleep quality index (PSQI) score, Hamilton depression scale-17 (HAMD-17) score, insomnia severity index (ISI) score, fatigue assessment instrument (FAI) score before and after treatment and after 2 weeks of treatment completion (follow-up) were observed in the two groups, and the serum level of γ-aminobutyric acid (GABA) before and after treatment was detected in the two groups, and the clinical efficacy and safety were evaluated. RESULTS: After treatment and in the follow-up, the sub-item scores and total scores of PSQI in both groups were reduced compared with those before treatment (P<0.001); except for the score of daytime dysfunction in the follow-up, the scores of sleep quality, sleep duration, daytime dysfunction, and total scores of PSQI in the observation group were lower than those in the control group (P<0.05). After treatment and in the follow-up, the HAMD-17, ISI and FAI scores in both groups were reduced compared with those before treatment (P<0.001); the scores in the observation group were lower than those in the control group (P<0.05). After treatment，the serum levels of GABA in both groups were increased compared with those before treatment (P<0.05); the level in the observation group was higher than that in the control group (P<0.05). The total effective rate of treating chronic insomnia in the observation group was 96.7% (29/30), which was higher than 80.0% (24/30) in the control group (P<0.05); and the total effective rate of improving mild depressive state was 93.3% (28/30), which was higher than 66.7% (20/30) in the control group (P<0.001). During the treatment period, no serious adverse reactions occurred in both groups. CONCLUSION Acupuncture combined with bamboo-based medicinal moxibustion has definite efficacy in the treatment of chronic insomnia complicated with mild depressive state, and has synergistic efficacy in improving sleep quality, sleep duration, daytime dysfunction and depressive state, its action mechanism may be related to the increase of serum level of GABA.

BACKGROUND: The sirtuin family is well recognized for its crucial involvement in various cellular processes. Nevertheless, studies on its role in the human endometrium are limited. This study aimed to explore the expression and localization of the sirtuin family in the human endometrium, focusing on sirtuin 3 (SIRT3) and its potential role in the oxidative imbalance of the endometrium in polycystic ovary syndrome (PCOS). METHODS: Endometrial specimens were collected from both patients with PCOS and controls undergoing hysteroscopy at the Center for Reproductive Medicine, Peking University Third Hospital, from July to August 2015 and used for cell culture. The protective effects of SIRT3 were investigated, and the mechanism of SIRT3 in improving endometrial receptivity of patients with PCOS was determined using various techniques, including cellular bioenergetic analysis, small interfering ribonucleic acid (siRNA) silencing, real-time quantitative polymerase chain reaction, Western blot, immunofluorescence, immunohistochemistry, and flow cytometry analysis. RESULTS: The sirtuin family was widely expressed in the human endometrium, with SIRT3 showing a significant increase in expression in patients with PCOS compared with controls ( P <0.05), as confirmed by protein and gene assays. Concurrently, endometrial antioxidant levels were elevated, while mitochondrial respiratory capacity was reduced, in patients with PCOS ( P <0.05). An endometrial oxidative stress (OS) model revealed that the downregulation of SIRT3 impaired the growth and proliferation status of endometrial cells and reduced their receptivity to day 4 mouse embryos. The results suggested that SIRT3 might be crucial in maintaining normal cellular state by regulating antioxidants, cell proliferation, and apoptosis, thereby contributing to enhanced endometrial receptivity. CONCLUSIONS Our findings proposed a significant role of SIRT3 in improving endometrial receptivity in patients with PCOS by alleviating OS and regulating the balance between cell proliferation and apoptosis. Therefore, SIRT3 could be a promising target for predicting and improving endometrial receptivity in this patient population.

Objective To evaluate the clinical efficacy of a novel sleep-aid decoction in treating elderly insomnia patients with different traditional Chinese medicine (TCM) constitutional types, and its effects on neurotransmitter and inflammatory factor levels. Methods A total of 200 patients with four different TCM constitutions-peaceful, Qi-deficient, Yin-deficient, and Yang-deficient-were recruited. Peripheral blood neurotransmitter and inflammatory factor levels were measured for variations among insomnia patients across different constitutions. These patients were treated using the novel sleep-aid decoction, the effects of which were evaluated based on changes in neurotransmitters and inflammatory factors. Results Compared to the peaceful constitution group, insomnia patients with Qi-deficient, Yin-deficient, and Yang-deficient constitutions exhibited significantly elevated baseline levels of neurotransmitters (5-HT, GABA) and inflammatory factors (IL-6, TNF-α, IL-1β, CRP). Following the treatment, the Qi-deficient and Yin-deficient groups showed a marked increase in 5-HT levels, restored balance of Glu, GABA, and melatonin, and significant reductions in IL-6 and TNF-α levels. The overall effective rate was 83.5%, with optimal efficacy observed in the Qi-deficient (97.72%) and Yin-deficient (95.34%) groups. Conclusion The novel sleep-aid decoction is effective in treating insomnia in elderly patients, with the best results observed in the Qi-deficient and Yin-deficient constitution groups.

Objective To investigate the effects of remazolam on melatonin secretion,sleep rhythm and postoperative delirium(POD)in elderly patients undergoing spinal surgery.Methods A total of 160 elderly patients,76 males and 84 females,aged 65-80 years,BMI 18.5-24.0 kg/m2,ASA physical status Ⅱ or Ⅲ,from November 2023 to January 2024 undergoing spinal surgery(lumbar interbody fusion,posterior approach)under general anesthesia were selected.The patients were divided into two groups by random number table method:the remazolam group(group R)and the propofol group(group P),80 pa-tients in each group.Group R was given remazolam 0.3 mg/kg for anesthesia induction,and then continued to pump remazolam 0.3-0.8 mg·kg-1·h-1 for anesthesia maintenance.Group P was given propofol 2.0 mg/kg for anesthesia induction,and then continued to pump propofol 4-6 mg·kg-1·h-1 for anesthesia maintenance.The levels of melatonin and cortisol were recorded at 04:00 a.m.on the day of surgery,1 day,2 and 3 days after surgery.Pittsburgh sleep quality index(PSQI)and VAS pain scores at rest were recorded 1 day before surgery,1 day and 2 days after surgery and before discharge.The occurrence of POD and post-operative sleep disorder(POSD)were recorded.The duration of extubation,PACU stay time,total analgesia pump compressions,effective analgesia pump compressions,number of remedial analgesia cases,intraoperative hypotension,postoperative nausea and vomiting,dizziness,respiratory depression and other adverse events were recorded.Results Compared with group P,the extubation time and PACU residence time in group R were significantly shortened(P＜0.05),the level of melatonin was significantly increased while the level of cortisol was significantly decreased at 4:00 a.m.,and the PSQI was significantly decreased 1 day after surgery(P＜0.05),the incidence of POD,POSD,and intraoperative hypotension were signifi-cantly decreased(P＜0.05).There were no significant differences in extubation time,total and effective times of analgesic pump,rate of remedial analgesia,intraoperative hypotension,postoperative nausea,vom-iting,dizziness and respiratory depression between the two groups.Conclusion Remazolam has little effect on the secretion rhythm of melatonin and cortisol and the sleep rhythm after spinal surgery in elderly pa-tients,and the recovery is faster,which can reduce the incidence of POD and alleviate the sleep disorder af-ter spinal surgery.

The STAR tool was used to evaluate and analyze the science, transparency, and applicability of Chinese pathology guidelines and consensus published in medical journals in 2022. There were a total of 18 pathology guidelines and consensuses published in 2022, including 1 guideline and 17 consensuses. The results showed that the guideline score was 21.83 points, lower than the overall guideline average (43.4 points). Consensus ratings scored an average of 27.87 points, on par with the overall consensus level (28.3 points). Areas that scored above the overall level were "conflict of interest" and "working groups", while areas that scored below the overall level were "proposals", "funding", "evidence", "consensus approaches" and "accessibility". To sum up, the formulation of pathology guidelines and consensuses in 2022 is not standardized, and the evidence retrieval process, evidence evaluation methods and grading criteria for recommendations on clinical issues are not provided in the formulation process; the process and method for reaching consensus are not provided, the plan is lacking, and registration is not carried out. It is therefore suggested that guidelines/consensus makers in the field of pathology should attach importance to evidence-based medical evidence, strictly follow guideline formulation methods and processes, further improve the scientific, applicable and transparent guidelines/consensuses in the field, and better provide support for clinicians and patients.

Objective:To investigate the application value of enhanced recovery after surgery (ERAS) in perioperative period of laparoscopic sleeve gastrectomy (LSG).Method:The retrospective cohort study was conducted. The clinical data of 1 181 patients undergoing LSG in the Sir Run Run Shaw Hospital, Affiliated with the Zhejiang University School of Medicine from January 2021 to December 2023 were collected. There were 242 males and 939 females, aged (31±8)years. Of 1 181 patients, 598 cases receiving routine perioperative care were divided into the control group, and 583 cases receiving perioperative care with ERAS were divided into the ERAS group. Measurement data with normal distribution were represented as Mean± SD, and the independent sample t test was used for comparison between the groups. Measurement data with skewed distribution were represented as M( Q1, Q3), and the Mann-Whitney rank sum test was used for comparison between the groups. Count data were expressed as absolute numbers or percentages, and the chi-square test or Fisher exact probability were used for comparison between the groups. Repeated measurement data were analyzed using the repeated ANOVA, with baseline scores as covariates. Simple effects analysis was conducted in case of interaction, and multiple comparisons were adjusted using the Bonferroni method. Results:(1) Postoperative outcomes. The numerical rating scale (NRS) scores for pain at immediate return to the ward and on the third postoperative mornings changed from 5.35±0.93 to 2.57±0.83 in the control group, versus changed from 3.15±0.93 to 0.70±0.65 in the ERAS group, showing significant difference between the two groups ( Ftime=66.58, Fgroup=1 765.85, Finteraction=6.90, P<0.05). After adjusting NRS scores for pain at immediate return to the ward as the baseline, results of simple effects analysis showed that on the third postoperative mornings, the NRS scores in the ERAS group were lower by 1.89, 1.53, and 1.76 respectively compared to the control group ( P<0.05). Cases with nausea at immediate return to the ward and on the third postoperative mornings changed from 497 to 97 in the control group, versus changed from 198 to 11 in the ERAS group, showing signifi-cant difference between the two groups ( χ2=294.45, 398.76,209.39, 73.00, P<0.05). Cases with vomiting at immediate return to the ward and on the third postoperative mornings changed from 243 to 41 in the control group, versus changed from 51 to 2 in the ERAS group, showing significant difference between the two groups ( χ2=160.54, 149.37, 71.76, 35.69, P<0.05). The duration of postoperative hospital stay was (3.22±0.65)days in the control group, versus (2.17±0.49)days in the ERAS group, showing a significant difference between the two groups ( t=-11.89, P<0.05). (2) Complications. The incidence of cases with dehydration within postoperative 30 days was 0.50%(3/598) in the control group, versus 0.69%(4/583) in the ERAS group, showing no significant difference between the two groups ( P>0.05). None of patient in the control group and the ERAS group experienced bleeding, gastric leakage, intra-abdominal infection, and no patient had unplanned secondary surgery within postoperative 30 days. Conclusions:ERAS in perioperative period of LSG are safe and feasible. Compared to routine care, ERAS can significantly reduce postoperative pain, decrease the incidence of postoperative nausea and vomiting, shorten the postoperative hospital stay, and do not increase the rate of postoperative complications or unplanned secondary surgeries within postoperative 30 days.

Objective:To explore the therapeutic effect of HEOS hysteroscopic surgery on patients with uterine fibroids and its effect on ovarian function and trauma response indicators.Methods:The clinical data of 104 patients with uterine fibroids admitted to Shangqiu Fifth People's Hospital from Jan 2020 to Mar 2023 were retrospectively analyzed and were divided into 2 groups according to different surgical protocols.A total of patients who underwent HEOS hysteroscopic surgery were enrolled in HEOS group and 52 patients who underwent conventional hysteroscopic electroresection(TCRPR)were enrolled in TCRPR group.The surgical and postoperative recovery indicators,surgical effects,ovarian function before and after surgery[estradiol(E2),luteinizing hormone(LH),follicle-stimulating hormone(FSH)],trauma response indicators[interleukin-6(IL-6),interleukin-17(IL-17),angiotensin Ⅱ(Ang Ⅱ)],and incidence of complications were compared between the two groups.Results:The operation time,postoperative exhaust time,time of the white blood cell count returning to normal,and hospitalization time in HEOS group were shorter than those in TCRPR group,and the intraoperative blood loss was less than that in TCRPR group(P<0.01).At 1 d after operation,serum levels of IL-6,IL-17 and Ang Ⅱ in 2 groups were higher than those before operation,and serum levels of IL-6,IL-17 and Ang Ⅱ in HEOS group were lower than those in TCRPR group(P<0.01).The excellent and good rate of operation in HEOS group was 98.08％(51/52),which was higher than that in TCRPR group[84.62％(44/52)](P<0.05).At 3 months after operation,the serum E2 level was lower and the serum LH and FSH levels of 2 groups were higher than those before operation,and the serum E2 level of HEOS group was lower than that of TCRPR group,and the serum LH and FSH levels were higher than those of TCRPR group(P<0.01).The incidence of complications in HEOS group was 1.92％(1/52),which was lower than that of TCRPR group[17.31％(9/52)](P<0.05).Conclusion:Compared with conventional TCRPR in the treatment of uterine fibroids,hysteroscopic surgery with HEOS is more helpful to improve the surgical effect,optimize the surgical and postoperative recovery indicators,improve ovarian function,reduce complications,and had less traumatic reactions.
