Stroke is the leading cause of death and disability among adults in China， and its common complications include digestive system abnormalities， cognitive impairment， depression， stroke-associated pneumonia， and hemiplegia. The combination of traditional Chinese and Western medicine has great potential in treating post-stroke complications. Xinglou Chengqitang （XLCQT） is a representative prescription of alleviating the disease in the upper part by treating the lower part. It has definite therapeutic effect and high safety. Clinically， XLCQT is often used to treat stroke and its complications. However， the quantity and quality of clinical trials of XLCQT in treating post-stroke complications need to be improved. Additionally， since the basic research is weak， the material basis and multi-target mechanism for the efficacy of this prescription are unknown. This article reviews XLCQT in terms of the pharmacodynamic basis， medicinal properties， safety evaluation， and progress in clinical research and mechanisms in treating post-stroke complications. This article summarizes 22 key active ingredients of XLCQT in treating acute stroke complicated with syndrome of phlegm heat and fu-organ excess. Among these key active ingredients， resveratrol， kaempferol， luteolin， chrysoeriol， apigenin， （+）-catechin， and adenosine have good pharmacokinetic properties and high bioavailability. The mechanisms of XLCQT in treating post-stroke complications are complex， including inflammatory response， brain-gut axis， hypothalamic-pituitary-adrenal （HPA） axis， intestinal flora， neurotrophic factors， autophagy， oxidative stress， and free radical damage. This review helps to deeply understand the pharmacodynamic basis and mechanisms of XLCQT in treating post-stroke complications and provides a theoretical basis for the clinical application of XLCQT against post-stroke complications and the development of drugs.

Objective To analyze the trends in disease burden and risk factors of depression among the elderly population in China from 1990 to 2021,and to provide a theoretical basis for the prevention,treatment,and policy-making of geriatric depression in China.Methods Data on the disease burden of geriatric depres-sion in China from 1990 to 2021,including the number of incident cases,disability-adjusted life years(DALYs),incidence rate,and DALY rate,were extracted from the 2021 Global Burden of Disease(GBD)database.The Joinpoint regression model was used to analyze the trends by calculating the annual percentage change(APC)and average annual percentage change(AAPC).The autoregressive integrated moving average(ARIMA)model was employed to predict the disease burden of geriatric depression over the next five years.Population attributable fractions(PAFs)were used to describe the risk factors for geriatric depression in China in 1990 and 2021.Results From 1990 to 2021,the number of incident cases and the incidence rate of geri-atric depression in China showed an overall upward trend.The most significant increase in incidence was ob-served in the 60-64 age group,while the prevalence rate increased notably in the ≥ 95 age group.The DALY rate showed the most pronounced upward trend in the 65-69 age group.The incidence,prevalence,and DALY rates of geriatric depression were higher in women than in men.Major risk factors included child-hood sexual abuse and intimate partner violence,with the impact of intimate partner violence being particular-ly significant among women.The ARIMA model predicted that the incidence,prevalence,and DALY rates of geriatric depression in China would decline over the next five years,with a greater decline observed in women than in men.Conclusions From 1990 to 2021,the incidence,prevalence,and DALY rates of geriatric de-pression in China showed an overall upward trend,with higher rates observed in women than in men.Greater attention should be paid to the elderly female population,with a focus on early prevention to reduce the dis-ease burden of geriatric depression.

Objective:To explore the application effect of virtual reality technology in preoperative anxiety of patients with hand trauma, aiming to improve the negative psychological state of patients before surgery.Methods:A prospective non-randomized controlled trial was conducted. A convenience sampling method was used to select 116 patients with hand trauma who underwent surgical treatment at Wuxi Ninth People′s Hospital from January 2022 to December 2023 as the research subjects. They were divided into an intervention group and a control group according to the treatment time, with 58 cases in each group. The control group received routine nursing intervention, while the intervention group received nursing intervention based on virtual reality technology in addition to the routine care. The preoperative anxiety, uncertainty of illness and subjective well-being of the two groups were compared before and after the intervention.Results:Three cases dropped out in the control group and six in the intervention group, with 55 and 52 patients completing the study in the control and intervention groups, respectively. In the control group, there were 29 males and 26 females, with an age of (40.60 ± 2.09) years. In the intervention group, there were 32 males and 20 females, with an age of (41.27 ± 10.55) years. After the intervention, the scores of the Self-Rating Anxiety Scale and the Uncertainty in Illness Scale in the intervention group were 52.81 ± 5.47 and 62.87 ± 4.26, respectively, which were lower than those in the control group 58.20 ± 7.29 and 67.41 ± 4.15, with statistically significant differences ( t=-4.31, -5.60, both P<0.05). The Index Well-Being score of the intervention group was 7.17 ± 1.15, higher than that of the control group 6.09 ± 0.57, with a statistically significant difference ( t=6.19, P<0.05). Conclusions:Virtual reality technology can effectively alleviate preoperative anxiety, reduce the uncertainty of illness and enhance subjective well-being in patients with hand trauma, which is beneficial to the physical and mental health of patients.

Osteoarthritis （OA） is a common degenerative joint disease with a rising incidence rate year by year. Treatment often relies on analgesics and non-steroidal anti-inflammatory drugs （NSAIDs）， which can lead to gastrointestinal damage with long-term use and the recurrence of symptoms. Chinese medicine has a long history of preventing and treating OA， with widespread application and fewer side effects. It offers unique advantages such as a broad treatment scope， multiple targets， and pathways. The effective components of Chinese medicine can reduce the content of reactive oxygen species （ROS）， relieve oxidative stress （OS） damage， and increase the antioxidant capacity of the body by interfering with the expression of biomarkers of OS response such as malondialdehyde （MDA） and superoxide dismutase （SOD）. Through the modulation of signaling pathways such as nuclear factor E₂-related factor 2 （Nrf2）/heme oxygenase-1 （HO-1）， phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）， nuclear factor kappa B （NF-κB）， c-Jun N-terminal kinase （JNK）， NOD-like receptor protein 3 （NLRP3）， and osteoprotegerin （OPG）， they downregulated the expression of inflammatory factors such as interleukin-6 （IL-6）， interleukin-1β （IL-1β）， and tumor necrosis factor-α （TNF-α）， thereby effectively relieving local joint inflammation， protecting chondrocytes and bone tissue， inhibiting chondrocyte apoptosis， and further alleviating the progression of OA. Currently， there are still certain limitations in the medical research status and development trends of OA， necessitating the continued advancement of traditional Chinese medicine. This paper reviewed the literature on the regulation of OS response by effective components of Chinese medicine for the prevention and treatment of OA， providing new directions and ideas for future research.

Objective:To explore the current status and influencing factors of fertility intention to have a third child among childbearing age women in Heilongjiang Province under three-child policy.Methods:From January to April 2023, convenience sampling was used to select 10 600 women of childbearing age from ten districts and counties in five cities in Heilongjiang Province (Jiamusi, Qiqihar, Harbin, Heihe, Suihua) as research subjects. The Fertility Intention to Have a Third Child Questionnaire among Childbearing Age Women in Heilongjiang Province was used to investigate women of childbearing age. Multi-class Logistic regression was used to explore the influencing factors of fertility intention of childbearing age women to have a third child.Results:A total of 10 600 questionnaires were distributed, and 9 554 valid questionnaires were collected, with a valid response rate of 90.13% (9 554/10 600). Among 9 554 women of childbearing age, 2 248 had the intention to have a third child, 5 036 had no intention, and 2 270 were uncertain. Multi-class Logistic regression analysis showed that age, education level, per capita monthly income of the family, occupation, fertility status, pregnancy complications, economic pressure to have a third child, parents' attitudes towards having a third child, and satisfaction with childcare services were the influencing factors of the fertility intention of childbearing age women in Heilongjiang Province to have a third child ( P<0.05) . Conclusions:Under the three-child policy, women of childbearing age in Heilongjiang Province have a low intention to have a third child. Relevant departments should formulate policies based on the influencing factors.

In multiple areas such as science, technology, and economic activities, it is necessary to unify the management of repetitive tasks or concepts by standardization to obtain the best order and high efficiency. Organoids, as living tissue models, have rapidly developed in the past decade. Organoids can be used repetitively for in vitro culture, cryopreservation, and recovery for further utilization. Because organoids can recapitulate the parental tissues' morphological phenotypes, cell functions, biological behaviors, and genomic profiles, they are known as renewable "living biobanks". Organoids cover two mainstream fields: Adult stem cell-derived organoids (also known as patient-derived organoids) and induced pluripotent stem cell-derived and/or embryonic stem cell-derived organoids. Given the increasing importance of organoids in the development of new drugs, standardized operation, and management in all steps of organoid construction is an important guarantee to ensure the high quality of products. In this review, we systematically introduce the standardization of organoid construction operation procedures, the standardization of laboratory construction, and available standardization documents related to organoid culture that have been published so far. We also proposed the challenges and prospects in this field.

Objective:To study the complications and prognosis of extremely premature infants(EPIs) with gestational age (GA) <28 w.Methods:From January 2016 to December 2020, EPIs with GA <28 w admitted to NICU of our hospital were retrospectively studied. Clinical data of the infants and their mothers during pregnancy were reviewed. According to the prognosis, the infants were assigned into the survival group, the death group and the withdrawal group. According to GA, the infants were assigned into <26 w goup, 26~26 +6 w group, ≥27 w group. According to birth weight (BW), the infants were assigned in to ≤750 g group, 750~999 g group and ≥1 000 g group. SPSS 26.0 was used for data analysis. Results:A total of 265 EPIs were included, 122 (46.0%) in the survival group, 47 (17.7%) in the death group and 96 (36.2%) in the withdrawal group. GA and BW of the survival group were significantly higher than the death group and the withdrawal group ( P<0.05). The incidences of tracheal intubation (92.2%) and pulmonary hemorrhage (42.2%) in the death group were the highest among the three groups. The survival group had the highest application of prenatal glucocorticoids (80.3%) and pulmonary surfactants (99.2%) ( P<0.05). In the survival group, the top 3 common complications were bronchopulmonary dysplasia (BPD) (68.0%), pulmonary infections (65.6%) and neonatal sepsis (34.4%). The survival rate increased with GA and BW. Conclusions:The survival rate of EPIs is closely correlated with GA and BW. EPIs with pulmonary hemorrhage and tracheal intubation have poor prognosis. Prenatal glucocorticoids and pulmonary surfactant may improve clinical outcome. BPD and pulmonary infections are common complications of surviving EPIs.
