Journal of Apoplexy and Nervous Diseases 2026;43(1):47-51
Objective To explore the changes in serum lactate dehydrogenase (LDH), monocyte chemoattractant protein-1 (MCP-1), and transcription factor 4 (TCF4) levels in patients with cerebral small vessel disease complicated by depression and their clinical significance. Methods According to the inclusion and exclusion criteria, 90 patients admitted to the Kailuan General Hospital between January 2022 and August 2024 were selected as the study subjects, including 27 patients diagnosed with cerebral small vessel disease complicated by depression and 63 patients with cerebral small vessel disease uncomplicated by depression. An additional 45 healthy individuals with normal head MRI findings and no mental disorders during the same period at the hospital were selected as the control group. General information was collected from the three groups, including age, body mass index, systolic blood pressure, and diastolic blood pressure.The general information and the levels of serum LDH,MCP-1,and TCF4 in the three groups were compared. The correlations of serum LDH,MCP-1,and TCF4 levels with HAMD score in patients with cerebral small vessel disease and depression were analyzed. Logistic regression was applied to analyze possible factors leading to depression in patients with cerebral small vessel disease.The receiver operating characteristic curve was applied to analyze the efficacy of serum LDH, MCP-1, and TCF4 levels in diagnosing depression in patients with cerebral small vessel disease. Results The levels of serum LDH, MCP-1,and TCF4 were significantly higher in the cerebral small vessel disease complicated by depression group than in cerebral small vessel disease uncomplicated with depression group and the control group (P<0.05), and these levels were significantly higher in the cerebral small vessel disease uncomplicated with depression group than in the control group (P<0.05).The serum LDH,MCP-1 and TCF4 were positively correlated with HAMD score in patients with cerebral small vessel disease complicated with depression(r=0.606,0.798,0.672,all P<0.001).Serum LDH, MCP-1, and TCF4 were influencing factors for depression in cerebral small vessel disease(P<0.05).The area under the receiver operating characteristic curve of LDH, MCP-1,and TCF4 in combination in the diagnosis of depression in cerebral small vessel disease was 0.917, which was superior to serum LDH, MCP-1, and TCF4 alone (ZLDH-combination=2.457,P=0.014;ZMCP-1-combination=2.384, P=0.017; ZTCF4-combination=2.317, P=0.021). Conclusion Serum LDH, MCP-1, and TCF4 levels increased in patients with cerebral small vessel disease complicated with depression. Their combination is valuable in the diagnosis of cerebral small vessel disease complicated with depression.

BACKGROUND AND OBJECTIVES
Climate anxiety is an emerging concept defined as increased anxiety about climate change and has been linked to negative mental health outcomes. As a relatively new concept, only a few have characterized it and its relationship with mental health, especially in the Global South populations. This study aimed to investigate the relationship between climate anxiety and depressive symptoms among undergraduate students from a college in a higher education institution in Manila, Philippines. Specifically, it aimed to (1) determine the proportion of undergraduate students who reported high levels of climate anxiety and depressive symptoms; and (2) determine the association between climate anxiety and depressive symptoms.
METHODSUsing a cross-sectional design and a convenience sampling method, the investigators collected data through an online survey to assess levels of climate anxiety and depressive symptoms using the Climate Change Anxiety Scale (CCAS) and the Patient Health Questionnaire 9 (PHQ-9), respectively. Data was analyzed using multiple logistic regression.
RESULTSAmong the 148 respondents (N=325), 14.86% had high climate anxiety (i.e., CCAS score >= 3) and 62.84% had high depressive symptoms (i.e., PHQ-9 score >= 10). Regression analysis showed that the odds of those having high climate anxiety reporting high depressive symptoms are higher than those with low climate anxiety, though this is not significant (OR = 2.53, p=0.144).
CONCLUSIONThe study verifies the existence of climate anxiety among undergraduate students and reflects an alarming mental health situation in the selected college. It is recommended that wide-scope investigations on the current state of climate anxiety and mental health among the youth be done to verify their impacts, along with inter-sectoral efforts such as increasing awareness through health education interventions to improve the youths’ mental health literacy and resilience to the effects of climate change, and promoting climate change-responsive mental health services to address these as pressing threats to youth health.

INTRODUCTION:
Adolescent depression is prevalent, and teen suicide rates are on the rise locally. A systemic review to understand associated risk and protective factors is important to strengthen measures for the prevention and early detection of adolescent depression and suicide in Singapore. This systematic review aims to identify the factors associated with adolescent depression in Singapore.
METHODS:
A systematic search on the following databases was performed on 21 May 2020: PubMed, EMBASE and PsycINFO. Full texts were reviewed for eligibility, and the included studies were appraised for quality using the Newcastle Ottawa Scale. Narrative synthesis of the finalised articles was performed through thematic analysis.
RESULTS:
In total, eight studies were included in this review. The four factors associated with adolescent depression identified were: (1) sociodemographic factors (gender, ethnicity); (2) psychological factors, including childhood maltreatment exposure and psychological constructs (hope, optimism); (3) coexisting chronic medical conditions (asthma); and (4) lifestyle factors (sleep inadequacy, excessive internet use and pathological gaming).
CONCLUSION
The identified factors were largely similar to those reported in the global literature, except for sleep inadequacy along with conspicuously absent factors such as academic stress and strict parenting, which should prompt further research in these areas. Further research should focus on current and prospective interventions to improve mental health literacy, targeting sleep duration, internet use and gaming, and mitigating the risk of depression in patients with chronic disease in the primary care and community setting.

INTRODUCTION:
In the early phase of the coronavirus disease 2019 (COVID-19) pandemic, children with COVID-19 in Singapore required hospital isolation. We aimed to explore the psychological experiences of children and their caregivers isolated in a tertiary university hospital due to COVID-19.
METHODS:
A prospective mixed-methods design was used to evaluate the psychological status of hospitalised family units with one or more children aged <18 years who had severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Patient medical records were reviewed for demographic and clinical information. Parents and children ≥7 years of age underwent a psychologist-administered telephone-based interview. Self-reported, age-appropriate instruments, Short Mood and Feelings Questionnaire, and Screen for Adult/Child Anxiety-Related Disorders, were used to assess anxiety and depression, respectively. Participants were also interviewed qualitatively.
RESULTS:
Fifteen family units were hospitalised between March 2020 and May 2020. Of these, 13 (73%) family units were recruited. The median age of the children and median hospitalisation duration were 57 months and 21 days, respectively. Median number of COVID-19 polymerase chain reaction swabs performed for each child was eight. All children had asymptomatic to mild SARS-CoV-2 disease. The criteria indicative of anxiety disorder were met by 40% of adults and 80% of children, while the criteria indicative of separation anxiety were met by 60% of parents and 100% of children. One child met the criteria indicative of depression. Uncertainty, separation, prolonged hospitalisation and frequent swabs caused significant reported anxiety.
CONCLUSIONS
Families, especially children, had heightened anxiety while in hospital isolation. Therefore, home-based recovery from COVID-19 and psychological support for children and their families, with focus on early recognition of anxiety disorders, are recommended. We support review of paediatric isolation policy as the pandemic evolves.

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.

Chinese Acupuncture & Moxibustion 2025;45(4):510-515
This paper introduces FU Wenbin's clinical experience in treatment of post-stroke depression with holistic therapy of acupuncture and moxibusiton for Shugan Tiaoshen (soothing the liver and regulating the mind). In pathogenesis, post-stroke depression is associated with the loss of the mind control and the failure of the liver in maintaining the free flow of qi. In treating principle, soothing the liver qi and regulating the mind are equally important, and the holistic regulation is applicable with the combination of multiple therapies. During treatment, the four-gate points are stimulated at first to promote liver qi flowing, the acupoints of the conception vessel and the governor vessel (e.g. Zhongwan [CV12], Guanyuan [CV4], Baihui [GV20], Yintang [GV24+]) are combined to regulate the mind and regain the consciousness. The conditions of illness are differentiated in terms of excess and deficiency, and the point prescription is modified accordingly. Refined moxibustion is applied specially at Fengchi (GB20), Fengfu (GV16) and Wangu (GB12) to warm meridians, strengthen yang and nourish the mind. In the last step of treatment, shallow needling techniques, such as the pricking and bloodletting, intradermal needling and auricular acupuncture, are used to consolidate the curative effect.

OBJECTIVE:
To observe the clinical efficacy of heat-sensitive moxibustion robot for improving the depressive state of methamphetamine addicts during withdrawal period.
METHODS:
A total of 60 patients with methamphetamine addiction accompanied with depressive state were randomly divided into an observation group (40 cases, 4 cases dropped out) and a control group (20 cases, 2 cases dropped out). The control group received routine health education and addiction treatment in compulsory isolation drug rehabilitation center. On the basis of the treatment in the control group, in the observation group, the heat-sensitive moxibustion robot was used to locate sensitive points at the Shenque (CV8) and Danzhong (CV17), and dual-point sparrow-pecking moxibustion was delivered for 60 min per session. The moxibustion therapy was performed 4 times in the 1st week, 3 times in the 2nd and 3rd weeks respectively, and 2 times in the 4th week, for 12 times totally. The scores of Hamilton depression scale (HAMD), self-rating depression scale (SDS), visual analogue scale (VAS) for drug craving, Hamilton anxiety scale (HAMA), self-rating anxiety scale (SAS), and Pittsburgh sleep quality index (PSQI) were observed before treatment, at the end of the 2nd and 4th weeks of treatment, and 4 weeks after the treatment completion (follow-up) in the two groups.
RESULTS:
At each time point after treatment, in the observation group, the HAMD, VAS, HAMA and PSQI scores were decreased compared with those before treatment (P<0.01, P<0.001); at the end of the 4th week of treatment and in follow-up, the SDS and SAS scores were decreased compared with those before treatment (P<0.001, P<0.01). Compared before treatment, there were no significant differences in the above scores at each time point after treatment in the control group (P>0.05). In the observation group, at each time point after treatment, the HAMD and VAS scores were lower than those in the control group (P<0.01, P<0.001, P<0.05); at the end of the 4th week of treatment and in follow-up, the SDS and HAMA scores were lower than those in the control group (P<0.05, P<0.001); at the end of the 4th week of treatment, the PSQI score was lower than that in the control group (P<0.01).
CONCLUSION
Heat-sensitive moxibustion robot effectively improves depression, anxiety and sleep quality, and reduces drug craving in methamphetamine addicts during withdrawal period.

OBJECTIVE:
To observe the effects of Tongdu Tiaoshen acupuncture (acupuncture for unblocking the obstruction in the governor vessel and regulating the spirit) on the depression-like behavior and the hippocampal neuronal ferroptosis mediated by solute carrier family 7 member 11 (SLC7A11)/glutathione peroxidase 4 (GPX4) pathway in depression rats, and explore the mechanism of this therapy for depression.
METHODS:
Of 30 male SD rats of SPF grade, 24 rats were selected. According to the random number table, they were divided into a normal group (n=8) and a modeling group (n=16). The rats in the modeling group were subjected to chronic unpredictable mild stress (CUMS) for 28 consecutive days to establish depression model. After modeling, 16 successfully-modeled rats were randomly divided into a model group and an acupuncture group, 8 rats in each one. In the acupuncture group, Tongdu Tiaoshen acupuncture was applied to "Dazhui"(GV14), "Shuigou" (GV26), "Baihui" (GV20) and "Shenting" (GV24). This intervention measure was deliveredonce a day, continuously for 6 days. The intervention discontinued on day 7, and was completed in 4 weeks. Before and after modeling, and after intervention completion, the behavioristics detection was performed using sucrose preference experiment and open field experiment. After intervention, using hematoxylin-eosin (HE) and Nissl staining, the morphology of hippocampal neurons was observed; with Western blot method, the protein expression of GPX4, SLC7A11, Ferritin and acyl-CoA synthetase long-chain family 4 (ACSL4) in hippocampal tissues was detected; with the real-time fluorescence quantitative PCR adopted, the mRNA expression of GPX4, SLC7A11, Ferritin and ACSL4 was detected; and using colorimetry, the hippocampal iron content was determined.
RESULTS:
After modeling, the sucrose preference rates, the total distance of movement, the standing times and the boxes of horizontal crossing in the model group and the acupuncture group were lower than those in the normal group (P<0.01). After the intervention, the sucrose preference rates, the total distance of movement, the standing times and the boxes of horizontal crossing in the acupuncture group were higher than those in the model group (P<0.01, P<0.05). Compared with the normal group, the number of necrotic cells increased and the number of Nissl bodies decreased in the model group; and when compared with the model group, the neuronal pyknosis and necrosis were ameliorated, the cells were arranged more regularly, the neuronal structure was clear, the matrix was dense, the blood vessels were enriched and the number of Nissl bodies increased in the acupuncture group. In comparison with the normal group, the relative expression of protein and mRNA of hippocampal GPX4, SLC7A11 decreased (P<0.01), it increased in the expression of hippocampal Ferritin and ACSL4 (P<0.01) in the model group. When compared with the model group, in the acupuncture group, the relative expression of protein and mRNA of hippocampal GPX4, SLC7A11 was elevated (P<0.01, P<0.05), it was dropped for hippocampal Ferritin and ACSL4 (P<0.01). In the model group, the hippocampal iron content was elevated when compared with that in the normal group (P<0.01); and it was reduced in the acupuncture group when compared with that in the model group (P<0.05).
CONCLUSION
Tongdu Tiaoshen acupuncture attenuates depression-like behaviors in the depression rats, which may be related to regulating SLC7A11/GPX4 pathway and inhibiting neuronal ferroptosis in the hippocampus.

OBJECTIVE:
To observe the effects of Tongdu Tiaoshen acupuncture (for unblocking the obstruction in the governor vessel and regulating the spirit) on depression-like behavior and the hippocampal Endophilin A1/reactive oxygen species (ROS) pathway in the chronic unpredictable mild stress (CUMS) model rats, and explore the mechanism of this therapy for depression.
METHODS:
Forty-eight male SD rats of SPF grade were randomly divided into a normal group (n=12) and a modeling group (n=36). In the modeling group, CUMS was performed to establish depression model. The successfully-modeled rats were randomized into a model group, a Tongdu Tiaoshen acupuncture group (referred to as the acupuncture group), and a fluoxetine group, with 12 rats in each group. In the acupuncture group, "Baihui" (GV20), "Shenting" (GV24), "Shuigou" (GV26) and "Dazhui" (GV14) were stimulated with acupuncture. This intervention measure was delivered once a day, continuously for 6 days; it was discontinued on day 7 and was completed in 28 days. In the fluoxetine group, intragastric administration was done with fluoxetine solution (2.1 mg/kg), once a day, and for 28 consecutive days. Before and after modeling, and after intervention completion, the body mass, sucrose preference rate and the total distance of movement and the boxes of horizontal crossing in the open field experiment were observed in each group. After intervention, using HE staining, the hippocampal neuron morphology was observed; using Nissl staining, the hippocampal Nissl body number was counted. The hippocampal mitochondria was observed under transmission electron microscopy. The average fluorescence intensity of ROS in hippocampal was determined using flow cytometry. With Western blot method, the protein expression of Endophilin A1, growth associated protein 43 (GAP-43), and brain-derived neurotrophic factor (BDNF) in hippocampal was detected; and with RT-qPCR method, the mRNA expression of Endophilin A1, GAP-43, and BDNF was recorded. Using the immunofluorescence, the average fluorescence intensity of Endophilin A1, GAP-43, and BDNF in hippocampal tissue was determined.
RESULTS:
Compared with the normal group, in the model group, the body mass, sucrose preference rate, and the total distance of movement and the boxes of horizontal crossing in the open field experiment decreased (P<0.01); the hippocampal neuronal structure was unclear, the matrix was relatively loose, and the number of Nissl body decreased (P<0.01); mitochondrial structure was disarranged, the outer membrane was ruptured, mitochondrial cristae was irregular or missed; the average fluorescence intensity of ROS in hippocampal tissue, the protein and mRNA expression and the average fluorescence intensity of Endophilin A1 in hippocampal tissue increased (P<0.01), while the protein and mRNA expression of GAP-43 and BDNF and its average fluorescence intensity decreased (P<0.01). Compared with the model group, the acupuncture group and the fluoxetine group showed the increase in body mass, sucrose preference rate, the total distance of movement and the boxes of horizontal crossing in the open field experiment (P<0.05, P<0.01); the hippocampal neuronal structure became relatively clear, the matrix was relatively dense, and the number of Nissl body was elevated (P<0.01); mitochondrial structure got normal and disarranged slightly, the average fluorescence intensity of ROS in hippocampal tissue, the protein and mRNA expression and the average fluorescence intensity of Endophilin A1 in hippocampal tissue were reduced (P<0.01), while the protein and mRNA expression of GAP-43 and BDNF and the average fluorescence intensity rose (P<0.01, P<0.05). Compared with the fluoxetine group, the acupuncture group presented the increase in the average fluorescence intensity of ROS, the protein expression and the average fluorescence intensity of Endophilin A1, the protein expression of GAP-43 and the mRNA expression of BDNF (P<0.01, P<0.05), and the decrease of the protein expression and the average fluorescence intensity of BDNF, the mRNA expression of Endophilin A1, and the average fluorescence intensity of GAP-43 (P<0.01, P<0.05).
CONCLUSION
Tongdu tiaoshen acupuncture alleviates depression-like behaviors in CUMS model rats and protects hippocampal neurons, which may be related to suppressing Endophilin A1/ROS signaling pathway and attenuating oxidative stress reactions.
