Objective:To investigate the efficacy of lightroom therapy on depressive mood and sleep problems in patients with depression, and the potential effects on physiological indices related to circadian rhythms.Methods:From October 2021 to July 2023, 54 patients with acute-phase depression hospitalized in the Mental Health Center of the First Hospital of Hebei Medical University were recruited. The participants were randomly assigned to either medication combined with the bright light therapy group (bright light group, n=36) or medication combined with the dim light therapy group (dim light group, n=18). Both groups received light therapy for 2 weeks, at 10 000 lx in the bright light group and 300 lx in the dim light group. Both groups received 30 minutes of light therapy from 7:30-8:00 a.m daily over two weeks, followed up for 1 week post-treatment. The Hamilton Depression Rating Scale (HAMD 17) was used to assess patients′ depressive symptoms, and the Pittsburgh Sleep Quality Index (PSQI) was used to assess patients′ sleep quality at baseline, at the end of every week. The 32-Item Hypomania Checklist (HCL-32) was used at the end of week 2 to assess the risk of manic switching after treatment. Daily measurements of body temperature, heart rate, and blood pressure were taken before and after light therapy, along with recording adverse events related to the therapy. Paired t- tests were used to compare changes in physiological indicators before and after treatment, and repeated measures ANOVA was applied to compare clinical symptom changes between the two groups. Results:Thirty-one and fifteen patients completed this study in the bright light and dim light groups, respectively, with no statistically significant difference in dropout rates( P>0.05). There were significant interaction effects between the time and group for HAMD 17 and PSQI score( F=5.51,4.11, both P<0.05). Both groups showed significant reductions in HAMD 17 and PSQI scores at baseline, week 1, week 2, and week 3 ( P<0.001). In the bright light group, body temperature increased significantly post-treatment on days 1-4, day 7, and day 12 (all P<0.05). Heart rate elevated on day 5 ( P<0.05).Systolic blood pressure decreased on days 4, 5, 11, and 12 compared to the pre-treatment baseline(all P<0.05). In the dim light group, systolic blood pressure increased on day 11 ( P<0.05). Diastolic blood pressure in the bright light group decreased on days 1, 5, and 6( P<0.05). No serious adverse events, vision loss, ocular structural changes occurred in either group. No hypomania or mania episodes were observed. The incidence of adverse events did not differ significantly ( P>0.05). Conclusion:Medication combined with indoor bright light is more effective than the combination of dim light for depressive symptoms and sleep problems in patients with depression. Patients receiving bright light also may exhibit a higher body temperature, accelerated heart rate, and reduced blood pressure.

Objective:To explore the effects of childhood trauma on resting blood pressure, heart rate, and heart rate variability in patients with depression.Methods:A cross-sectional study was designed to prospectively collect clinical data on a total of 163 patients with depression, including 47 males and 116 females, aged 18-50 years,with mean[ M( Q1, Q3)] [29.0, (21.0, 37.0)]years, who were either the outpatients or the inpatients in the Mental Health Center of the First Hospital of Hebei Medical University from September 2022 to June 2024. The Childhood Trauma Questionnaire-Short form (CTQ-SF) was used to assess the experience of abuse and neglect during childhood. According to the CTQ-SF score, the subjects were divided into a trauma group ( n=80) and a non-trauma group ( n=83). The 17-item Hamilton Depression Scale (HAMD 17) and Hamilton Anxiety Scale (HAMA) were used to assess depressive and anxiety symptoms in the participants, respectively. A digital blood pressure monitor and an autonomic nervous system response detector were employed to measure resting blood pressure, heart rate, and heart rate variability (HRV). Spearman correlation analysis was used to examine the relationships between childhood trauma and resting blood pressure, heart rate, and HRV. Multiple linear regression analysis was performed to analyze factors influencing these parameters. The Bootstrap method was employed to test the potential mediating role of parasympathetic nervous system activity in the relationships between childhood trauma and resting blood pressure, and heart rate. Results:No significant difference was observed in resting heart rate between the trauma and non-trauma groups ( P>0.05). However, the trauma group exhibited higher resting systolic and diastolic blood pressure [(123.3±9.1) mmHg (1 mmHg=0.133 kPa) vs(116.9±10.8) mmHg, (80.0±8.6) mmHg vs (77.0±8.0) mmHg; Z=4.08, 2.24, all P<0.05]. HRV indices, including the standard deviation of normal to normal interval (SDNN), root mean square of successive differences (RMSSD), total power (TP), low frequency (LF), and high frequency (HF), were significantly lower in the trauma group [25.3 (19.4, 30.4) me vs 36.3 (27.4, 49.0) ms, 18.3 (12.9, 27.2) me vs 26.2 (19.0, 38.5) ms, 6.0(5.4, 6.5)ms 2vs 7.0(6.3, 7.4)ms 2,4.4(3.7,5.3)ms 2vs 5.8(4.9,6.3)ms 2, 4.2(3.4, 5.2)ms 2vs 5.2(4.6, 6.1)ms 2, respectively; all P<0.001]. Spearman correlation analysis showed that childhood trauma experiences in patients with depression were positively correlated with resting systolic blood pressure and diastolic blood pressure ( r=0.309, 0.236; P<0.01), childhood trauma was negatively correlated with HRV (SDNN, RMSSD, TP, LF, HF) ( r=-0.264, -0.274, -0.271, -0.235, -0.279; all P<0.01). Multiple linear regression analysis showed that childhood trauma was positively correlated with resting-state systolic blood pressure and resting-state diastolic blood pressure ( β=0.305, 0.291; all P<0.001). Childhood trauma was negatively correlated with RMSSD, TP, LF, and HF( β=-0.244, -0.249, -0.233, -0.263; all P<0.01). Mediation effect analysis showed that parasympathetic activity partially mediated the relationship between childhood trauma and resting systolic blood pressure (effect size 0.04, standard error 0.02, 95% CI=0.01-0.09), accounting for 14.29% (0.04/0.28) of the total effect. Conclusion:Childhood trauma experiences are associated with elevated resting blood pressure and reduced HRV in patients with depression. Decreased parasympathetic activity partially mediates the relationship between childhood trauma and elevated resting systolic blood pressure in these patients.

Objective:To explore the effects of the deep Theta burst stimulation (dTBS) applied to the bilateral dorsolateral prefrontal cortex on depressive symptoms and executive functions in patients with depression.Methods:The clinical data of a total of 98 patients with depression who were outpatients and inpatients in the Mental Health Center of the First Hospital of Hebei Medical University from June 2023 to October 2024 were prospectively collected, including 37 males and 61 females, aged 18-65 (37.4±13.3) years. Patients were randomly assigned to one of three groups: an active dTBS+drug therapy group (active stimulation group, n=33), a sham dTBS+drug therapy group (sham stimulation group, n=32), and a drug therapy group ( n=33). A shielding cover was added over the sham dTBS coil to increase the distance between the coil and the cortical surface, thereby achieving the sham stimulation effect. During each treatment, both active and sham dTBS were first applied by 1, 200 pulses of intermittent dTBS (diTBS) to the left dorsolateral prefrontal cortex, followed by 600 pulses of continuous dTBS (dcTBS) to the right dorsolateral prefrontal cortex. Before treatment and two weeks after treatment, the Hamilton Anxiety Scale (HAMA) and 17-Item Hamilton Depression Scale (HAMD 17) were used to evaluate patients′ depression and anxiety, and the Symbol Digit Coding Test of the Chinese Brief Cognitive Test (C-BCT) was used to assess the executive functions. The 32-item Hypomania Checklist (HCL-32) as well as the Mood Disorder Questionnaire (MDQ) were used to evaluate the risk of treatment-emergent mania. The primary outcomes included reduction rate in HAMD 17 and HAMA scores, as well as changes in the Symbol Digit Coding Test of the C-BCT. Secondary outcomes encompassed HAMD 17 treatment response rate, adverse events, and the risk of treatment-emergent mania. The differences in efficacy between the three groups were compared using one-way ANOVA and LSD post-hoc analysis (reduction rate in HAMD 17 scores, reduction rate in HAMA scores, and changes in the Symbol Digit Coding Test of the C-BCT). Results:At the end of the 2nd week of the treatment, the HAMD 17 reduction rate in the active stimulation group was higher than the sham stimulation group and the drug therapy group, with a significant difference (59.4 (46.9, 80.2) % vs 47.6 (31.2, 58.3) %, H=18.95, P=0.006; 59.4 (46.9, 80.2) % vs 35.5 (20.0, 50.0) %, H=31.10, P<0.001). The HAMA reduction rate in the active stimulation group and the sham stimulation group were higher than the drug therapy group, with a significant difference (52.6 (43.5, 65.7) % vs 2.1 (21.1, 58.8) %, H=21.31, P=0.002; 52.9 (41.7, 62.5) % vs 32.1 (21.1, 58.8) %, H=14.4, P=0.037). The changes in the symbol digit coding test of the C-BCT in the active stimulation group were significantly higher than the sham stimulation group and the drug therapy group (6.3±2.1 scores vs 2.9±3.2 scores, F=5.02, P=0.011; 6.3±2.1 scores vs 2.8±3.1 scores, F=5.02, P=0.009). The incidence rate of adverse events in the active stimulation group was 12.1% (4/33) and 3.1% (1/32) in the sham stimulation group, and there was no significant difference in the incidence of adverse events between the two groups (χ 2=0.17, P=0.355). Conclusion:Bilateral dTBS stimulation of the dorsolateral prefrontal cortex combined with drug therapy can improve depressive symptoms and executive functions, such as information processing speed, attention and working memory.

Objective:This study aimed to share preliminary experiences of single-incision plus two ports laparoscopic proximal gastrectomy with right-sided overlap and single-flap valvuloplasty (ROSF).Methods:Following the 6th edition of the Japanese Gastric Cancer Treatment Guidelines, proximal gastrectomy with lymphadenectomy was performed. Using a single-port approach, the esophagus was transected at least 2 cm above the tumor's upper margin with linear staplers. The stomach was then extracted through a periumbilical incision, and the proximal stomach was subsequently transected extracorporeally, while ensuring appropriate resection margins on both the greater and lesser curvatures. A single flap was created before returning the remnant stomach to the abdominal cavity and re-establishing pneumoperitoneum. The No.2 clip was used to grasp and elevate the esophageal stump. An incision was made at the right lower edge of the esophageal stump to guarantee that the esophageal lumen was open. The linear stapler was then inserted into the openings of the stomach and esophagus to perform a side overlap anastomosis with a length of 3 cm. Another barbed suture was used to close the common opening of the esophagus and the stomach, and the same barbed suture were used to suture the gastric wall to the lower edge of the muscle flap. The first barbed suture was then used to sequentially suture the proximal brim of the flap to the esophagus and the right brim of the flap to the right brim of the mucosal window. After completion of anastomosis, a drainage tube was inserted through the right upper port. This procedure was employed from November 2023 to March 2024 on five patients diagnosed with adenocarcinoma of the esophagogastric junction and upper stomach. The cohort consisted of three males and two females, with an age range of 62 to 75 years and a body mass index (BMI) of 13.7 to 24.2 kg/m2. All cases were preoperatively staged as T1-2N0M0, confirmed by endoscopic biopsy and enhanced CT scans of the chest, abdomen, and pelvis.Results:All five patients successfully underwent the surgery. The median surgery time was 180-325 minutes, with the intraoperative blood loss of 30-50 ml. The number of lymph nodes harvested ranged from 18 to 27. The time to first flatus, and restore liquid diet and was 2.0-5.0 and 1.0-3.0 days, respectively. The postoperative length of stay was 9.0-11.0 days. The pain scores on the Numeric Rating Scale (NRS). On the first day, the pain scores were 3.0 in two cases, 2.0 in two cases, and 1.0 in one case. On the second day, the pain scores were 2.0 in two cases and 1.0 in three cases. On the third day, the pain scores were 1.0 in four cases and 2.0 in one case. No short-term postoperative complications were observed, and there were no perioperative deaths.Conclusion:Single-incision plus two ports laparoscopic proximal gastrectomy with ROSF is safe and feasible.

Objective:To construct the impact factor model of primary traditional Chinese medicine (TCM) health management service quality, and put forward corresponding policy suggestions.Methods:In this cross-sectional study, the typical sampling and random sampling method were used to select 39 insiders of primary TCM health management service from 15 communities in Zhejiang Province from August to October in 2022. Interviews on service projects, implementation effects and impact factors were conducted, the three-level coding of interview record was carried out using the grounded theory research method, a model of impact factor for health management service quality of basic TCM was constructed, and the corresponding policy recommendations were put forward.Results:Based on the open coding of 39 original interview data, a total of 516 reference points were obtained, and 53 initial concepts related to the topic were formed and summarized into 17 first-level categories. Through the summary of main axis coding, 6 main categories of “policy environment”，“health literacy”，“community orientation”，“capacity building”，“health preference” and “conflict of interest” were extracted. The logical correlation between the six main categories were analyzed with selective coding, an impact factor model was constructed in accordance with the story line of factors affecting service quality. The story line of this model was as follows: first, the policy environment was the external guarantee of community TCM service quality; second, as the demand-side of the services, the health literacy and requirement of residents was the regulatory factor for service quality; in addition, the community played the role of the supply-side of the services, the service ability construction was the key factor, and the community functions and target orientation was the internal driving factor, meanwhile, the internal/external conflicts of interest had a negative constraint on the service quality.Conclusions:The guarantee intensity of external policy environment is limited, the service demand side pays insufficient attention, and the service supply side functions are absent at the present stage. It is necessary to improve the external policy environment, deepen the connection between supply and demand sides in the field of TCM health service, promote the capacity building of TCM service at the grass-roots level, balance the interests of relevant departments of TCM service, in order to improve the quality of TCM health management service at the grass-roots level.

Objective:To observe the anti-inflammatory and glycometabolic effects of glutathione(GSH)on macrophages in collagen induced arthritis(CIA)mice.Methods:①CIA model establishment and groups:A total of 14 female DBA/1J mice were ran-domly divided into:CIA+PBS group and CIA+GSH group.The mice were sacrificed on the 50th day,collecting serum and isolating bone marrow derived macrophages(BMDM),which were marked as BMDM1.②Trained immunity model establishment and groups:BMDM were isolated from normal DBA/1J mice,and were pretreated with histone H3K27 demethylases inhibitor(GSKJ1)or PBS for 2 h.Then,serum from CIA model mice in vivo was incubated for 24 h,and the samples were grouped as follows:(CIA+GSH)+PBS group,(CIA+GSH)+GSKJ1 group,(CIA+PBS)+PBS group,(CIA+PBS)+GSKJ1 group.Lipopolysaccharide(LPS)was adopted to stimulated cells on the 6th day,which were marked as BMDM2.③RNA sequencing was used to detect differentially expressed genes(DEGs)and their function in BMDM1 and BMDM2.q-PCR was adopted to estimate the mRNA levels of PFK and Idh3g.The culture supernatants were used to measure the protein levels of TNF-α and IL-6 by ELISA.Results:①Compared with CIA+PBS group,the mice in CIA+GSH group showed lighter of joint swelling(P<0.05),less arthritis index(P<0.05),HE staining suggested less inflam-matory cell infiltration,Safranin O-fast green staining showed more chondrocytes,TRAP staining indicated reduced osteoclasts.②In BMDM1,GO analysis showed that DEGs were mainly involved in glutathione derivative metabolic process,IL-6 production,inflammatory response,innate immune response,regulation of primary metabolic process and glycolipid binding,compared with CIA+GSH and CIA+PBS group.In CIA+GSH group,the mRNA level of PFK was significantly decreased(P<0.05),while Idh3g was also significantly up-regulated(P<0.05),and the expression of TNF-α,IL-6 were both reduced(P<0.05)compared with CIA+PBS group.③In BMDM2,GO analysis showed that DEGs were also involved in inflammatory response,activation of innate immune response,regulation of tumor necrosis factor production,positive regulation of IL-6 production,regulation of glycolytic process and 1,3-β-D-glucan binding between CIA+GSH and CIA+PBS group.Furthermore,in(CIA+GSH)+PBS group,PFK was decreased(P<0.05),Idh3g was up-regulated(P<0.05),and IL-6 was also significantly down-regulated(P<0.05)compared with(CIA+PBS)+PBS group.However,there was no significant difference in the expression of Idh3g and PFK,moreover,TNF-α and IL-6 were significantly up-regulated compared with(CIA+GSH)+GSKJ1 group and(CIA+GSH)+PBS group.Conclusion:GSH can regulate glycometabolism and inflammatory response of macrophages via demethylation of histone H3K27,and it can also alleviate CIA in mice.
