Prostate cancer is a prevalent and debilitating disease that necessitates effective prevention and treatment strategies. Green tea, a well-known beverage derived from the Camellia sinensis plant, contains bioactive compounds with potential health benefits, including catechins and polyphenols. This comprehensive review aims to explore the potential benefits of green tea in prostate cancer prevention and treatment by examining existing literature. Green tea possesses antioxidant, anti-inflammatory, and anti-carcinogenic properties attributed to its catechins, particularly epigallocatechin gallate. Epidemiological studies have reported an inverse association between green tea consumption and prostate cancer risk, with potential protection against aggressive forms of the disease. Laboratory studies demonstrate that green tea components inhibit tumor growth, induce apoptosis, and modulate signaling pathways critical to prostate cancer development and progression. Clinical trials and human studies further support the potential benefits of green tea. Green tea consumption has been found to be associated with a reduction in prostate-specific antigen levels, tumor markers, and played a potential role in slowing disease progression. However, challenges remain, including optimal dosage determination, formulation standardization, and conducting large-scale, long-term clinical trials. The review suggests future research should focus on combinatorial approaches with conventional therapies and personalized medicine strategies to identify patient subgroups most likely to benefit from green tea interventions.

This study aimed to investigate the effect of Jiaotai Pills on protein expression in the hippocampus of the rat model of chronic unpredictable mild stress(CUMS)-induced depression by quantitative proteomics and explore the anti-depression mechanism of Jiaotai Pills. The SD rats were randomized into control, model, Jiaotai Pills, and fluoxetine groups(n=8). Other groups except the control group were subjected to CUMS modeling for 4 weeks. After 4 weeks of continuous administration, the changes of behavior and pathological morphology of the hippocampal tissue were observed. Proteins were extracted from the hippocampal tissue, and bioinformatics analysis was performed for the differentially expressed proteins(DEPs) identified by quantitative proteomics. Western blot was employed to verify the key DEPs. The results showed that Jiaotai Pills significantly alleviated the depression behaviors and hippocampal histopathological changes in the rat model of CUMS-induced depression. A total of 5 412 proteins were identified in the hippocampus of rats, including 65 DEPs between the control group and the model group and 35 DEPs between the Jiaotai Pills group and the model group. There were 16 DEPs with the same trend in the Jiaotai Pills group and the control group, which were mainly involved in sphingolipid, AMPK, and dopaminergic synapse signaling pathways. The Western blot results of Ppp2r2b, Cers1, and Ndufv3 in the hippocampus were consistent with the results of proteomics. In conclusion, Jiaotai Pills may play an anti-depression role by modulating the levels of Ppp2r2b, Cers1, Ndufv3 and other proteins and regulating sphingolipid, AMPK, and dopaminergic synapse signaling pathways.

Objectives: To investigated the safety and efficacy of treating patients with acute non-ST-segment elevation myocardial infarction (NSTEMI) and elevated levels of N-terminal pro-hormone B-type natriuretic peptide (NT-proBNP) with levosimendan within 24 hours of first medical contact (FMC). Methods: This multicenter, open-label, block-randomized controlled trial (NCT03189901) investigated the safety and efficacy of levosimendan as an early management strategy of acute heart failure (EMS-AHF) for patients with NSTEMI and high NT-proBNP levels. This study included 255 patients with NSTEMI and elevated NT-proBNP levels, including 142 males and 113 females with a median age of 65 (58-70) years, and were admitted in the emergency or outpatient departments at 14 medical centers in China between October 2017 and October 2021. The patients were randomly divided into a levosimendan group (n=129) and a control group (n=126). The primary outcome measure was NT-proBNP levels on day 3 of treatment and changes in the NT-proBNP levels from baseline on day 5 after randomization. The secondary outcome measures included the proportion of patients with more than 30% reduction in NT-proBNP levels from baseline, major adverse cardiovascular events (MACE) during hospitalization and at 6 months after hospitalization, safety during the treatment, and health economics indices. The measurement data parameters between groups were compared using the t-test or the non-parametric test. The count data parameters were compared between groups using the χ² test. Results: On day 3, the NT-proBNP levels in the levosimendan group were lower than the control group but were statistically insignificant [866 (455, 1 960) vs. 1 118 (459, 2 417) ng/L, Z=-1.25,P=0.21]. However, on day 5, changes in the NT-proBNP levels from baseline in the levosimendan group were significantly higher than the control group [67.6% (33.8%,82.5%)vs.54.8% (7.3%,77.9%), Z=-2.14, P=0.03]. There were no significant differences in the proportion of patients with more than 30% reduction in the NT-proBNP levels on day 5 between the levosimendan and the control groups [77.5% (100/129) vs. 69.0% (87/126), χ²=2.34, P=0.13]. Furthermore, incidences of MACE did not show any significant differences between the two groups during hospitalization [4.7% (6/129) vs. 7.1% (9/126), χ²=0.72, P=0.40] and at 6 months [14.7% (19/129) vs. 12.7% (16/126), χ²=0.22, P=0.64]. Four cardiac deaths were reported in the control group during hospitalization [0 (0/129) vs. 3.2% (4/126), P=0.06]. However, 6-month survival rates were comparable between the two groups (log-rank test, P=0.18). Moreover, adverse events or serious adverse events such as shock, ventricular fibrillation, and ventricular tachycardia were not reported in both the groups during levosimendan treatment (days 0-1). The total cost of hospitalization [34 591.00(15 527.46,59 324.80) vs. 37 144.65(16 066.90,63 919.00)yuan, Z=-0.26, P=0.80] and the total length of hospitalization [9 (8, 12) vs. 10 (7, 13) days, Z=0.72, P=0.72] were lower for patients in the levosimendan group compared to those in the control group, but did not show statistically significant differences. Conclusions: Early administration of levosimendan reduced NT-proBNP levels in NSTEMI patients with elevated NT-proBNP and did not increase the total cost and length of hospitalization, but did not significantly improve MACE during hospitalization or at 6 months.

Objective:To investigate factors affecting the care needs of community-dwelling elderly people.Methods:A cross-sectional study was conducted.A face-to-face questionnaire survey was conducted using random samples of elderly people aged 60 years and above in six communities in Beijing to analyze the prevalence of diseases and care needs of elderly people in different age groups, and factors influencing elderly people's care needs.Univariate and multivariate Logistic regression analyses were used to analyze factors influencing these individuals' care needs based on basic personal situations, physical health status, economic situations, psychological and social status.Results:A total of 546 community-dwelling elderly people were recruited, with a mean age of(77.88±9.12)years.Cardiovascular and cerebrovascular diseases were consistently found to be the most common diseases in all age groups(60-69 years: 57.81% or 74/128; 70-79 years: 56.49% or 87/154; 80-89 years: 76.74% or 165/215; 90 years or over: 83.67% or 41/49); Care needs for groups aged 70 year or over were higher than for the group aged between 60-69( χ2=47.209, P<0.001). Elderly people with more than 2 diseases, long-term use of more than 1 drug, occasional constipation, and feeling loneliness or holding the view that caregivers do not need basic medical knowledge had a low need for care( OR=0.172, 0.006, 0.088, 0.112, 0.005, respectively, P<0.05 for all). Those with only one child, a history of pain, willing to pay more than ￥4 000 to hire a care-giver, or with partial disability were more likely to feel the need for care( OR=548.732, 5.941, 4.265, 7.373, respectively, P<0.05 for all). Conclusions:The care needs of elderly people living at home and aged over 60 in 6 communities in Beijing are affected by multiple factors such as their family structure, physical health status, economic status and psychological status.Elderly people need to have and accept multi-dimensional care services provided by knowledgeable and skillful caregivers to improve their quality of life.

Objective:To conduct a survey on the current situation of family nursing assistants for elderly people with chronic diseases and disability in the community from multiple dimensions such as personal information, work status, professional quality, difficult problems encountered in the nursing process, and solutions.Methods:From April to August 2022, a questionnaire survey was conducted among family nursing assistants of elderly people with chronic diseases and disability in six communities in Beijing using cluster sampling. We conducted a survey and analysis on the current situation of family nursing assistants for elderly people with chronic diseases and disability in the community from multiple dimensions, based on the presence or absence of professional qualification certificates for nursing assistants.Results:The study included 611 nursing assistants, aged (49.99±6.82) years, mainly composed of rural registered residence and education level below junior high school. Only 43.04% (263/611) of nursing assistants had professional qualification certificates for nursing assistants. Compared with those without professional qualification certificate for nursing assistants, those with professional qualification certificate for nursing assistants had statistical differences in gender, registered residence, education level, daily working hours, specific work content of care, monthly income, solutions to reduce the mobility of elderly nursing assistants, working years, feelings of caring for the daily health of elderly people with chronic diseases, psychological status, self-awareness about job, training to improve work skills, basic medical knowledge training, and reasons for not participating in training ( P<0.05). Nursing assistants reported a lack of medical and nursing knowledge and an urgent need for professional training and guidance from medical and nursing staff during the investigation of difficult issues encountered in their work. Conclusions:It is necessary to strengthen and improve the training of nursing professionals and basic medical knowledge of family nursing assistants for elderly people with chronic diseases and disability before and during work, which can help improve the level and quality of care provided by family nursing assistants.

OBJECTIVE: To observe the clinical efficacy of Tiaohe Yinyang acupotomy (acupotomy for regulating and harmonizing yin and yang) for knee osteoarthritis (KOA). METHODS: A total of 88 patients with KOA were randomized into a acupotomy group and a sham-acupotomy group, 44 cases in each group. In the acupotomy group, acupotomy was applied at yin side (4-5 high stress points i.e. pes anserinus and terminal of popliteus) and yang side (1-2 high stress points i.e. stimulation point of infrapatellar ligament and suprapatellar bursa) of knee joint. In the sham-acupotomy group, sham-acupotomy was applied at the same points as the acupotomy group. The treatment was given once a week for 2 weeks in the two groups. Before and after treatment, the Western Ontario and McMaster Universities arthritis index (WOMAC) score, visual analogue scale (VAS) score, thickness of medial and lateral collateral ligaments of knee joint, motion range of knee joint and plantar pressure distribution were observed in the two groups. In the follow-up of 3 months after treatment, the WOMAC and VAS scores were recorded in the acupotomy group. RESULTS: After treatment, the sub item scores (pain, stiffness and function) and total scores of WOMAC and VAS scores were decreased in the both groups (P<0.05), pain score, function score and total score of WOMAC and VAS score in the acupotomy group were lower than those in the sham-acupotomy group (P<0.05). Before and after treatment, there were no statistical differences in thickness of medial and lateral collateral ligaments of knee joint and motion range of knee joint between the two groups (P>0.05). After treatment, the plantar medial pressure was increased while the plantar lateral pressure was decreased (P<0.05), and the plantar force line moved medially in the acupotomy group. In the follow-up, the sub item scores and total score of WOMAC and VAS score were lower than those before and after treatment in the acupotomy group (P<0.05). CONCLUSION Tiaohe Yinyang acupotomy can improve the clinical symptoms of knee joint in patients with KOA by changing the local biological stress.

ObjectiveTo optimize the extraction and purification process of Gardeniae Fructus for industrial production， and to obtain the total iridoid and total crocin extracts. MethodOrthogonal test was used to optimize the water extraction process by taking contents of geniposide， genipin gentiobioside， gardenoside， crocin-1 and crocin-2 as indicators and the decocting time， decocting times and water amount as factors. The purification process was optimized by single factor test， and four different types of macroporous adsorption resins were screened. The process conditions such as resin type， maximum loading amount， water washing amount， ethanol concentration， ethanol dosage， and flow rate of sample loading were mainly investigated. In addition， the drying methods （vacuum drying and spray drying） of the extract were investigated， and a pilot scale-up verification test was carried out. ResultThe optimal water extraction process of Gardeniae Fructus was to add 15， 10 times the amount of water for decocting twice， 1 h each time. The optimal purification process was as follows：the water extract through SP825L macroporous resin column， the amount of crude drug-the amount of resin （1∶1.5）， the sample loading flow rate of 3 BV h^-1， adding 2 BV of water to remove impurities， adding 4 BV of 30% ethanol to obtain the iridoid part， then adding 3 BV of 70% ethanol to obtain the crocin part， collecting the ethanol lotion， and drying at 70 ℃. Under these conditions， the extraction amount of total iridoids was 590.75 mg·g^-1 with the transfer rate of 70.48%， and the yield of dry extract was 8.89%. The extraction amount of total crocins was 83.37 mg·g^-1 with the transfer rate of 22.20%， and the dry extract yield was 2.60%. ConclusionThe optimized extraction and purification process is stable and feasible with high extraction rate of active components， which is suitable for the industrial extraction and purification of active parts of Gardeniae Fructus.

Objective: To investigate the application and clinical efficacy of ultrasound debridement method in residual burn wounds. Methods: A retrospective cohort study was conducted. From August 2017 to August 2021, 64 patients with residual burn wounds who met the inclusion criteria were admitted to the 980^th Hospital of the Joint Logistic Support Force of PLA. According to the debridement method adopted for the residual wounds, the patients were divided into ultrasound debridement group (34 cases, 22 males and 12 females, aged (31±13) years) and traditional debridement group (30 cases, 19 males and 11 females, aged (32±13) years). After the corresponding debridement, the wounds of patients in the two groups were selected for stamp skin grafting or large skin grafting according to the wound site and skin donor status. For unhealed wounds after stage Ⅰ surgery, secondary debridement and skin grafting were be performed, with the wound debridement methods in the 2 groups being the same as those of stage Ⅰ, respectively. On postoperative day 3, drug-sensitive test was used to detect the bacteria in the wound and the positive rate of bacteria was calculate. On postoperative day 7, the survival rate of skin slices in wound and the incidence of subcutaneous hematoma were calculated. At discharge, wound healing time and debridement times of patients were counted, and the secondary debridement rate was calculated. Data were statistically analyzed with independent sample t test or chi-square test. Results: On postoperative day 3, the wounds in ultrasound debridement group were infected with Staphylococcus aureus in 2 cases and Pseudomonas aeruginosa in 2 cases, and the wounds in traditional debridement group were infected with Staphylococcus aureus in 5 cases, Pseudomonas aeruginosa in 3 cases, Acinetobacter baumannii in 1 cases, Klebsiella pneumoniae in 1 cases, and Enterobacter cloacae in 1 cases. The positive rate of bacteria of wound in ultrasound debridement group was significantly lower than that in traditional debridement group (χ²=5.51, P<0.05). On postoperative day 7, the survival rate of skin grafts in ultrasound debridement group was (92±5) %, which was significantly higher than (84±10) % in traditional debridement group (χ²=6.78, P<0.01); the incidence of subcutaneous hematoma in ultrasound debridement group was 17.6% (6/34), which was significantly lower than 40.0%( 12/30) in traditional debridement group, χ²=3.94, P<0.05. At discharge, the wound healing time in ultrasound debridement group was (11.0±2.0) d, which was significantly shorter than (13.0±3.1) d in traditional debridement group (t=3.81, P<0.01); the secondary debridement rate of wounds in ultrasound debridement group was 2.9% (1/34), which was significantly lower than 20.0% (6/30) in traditional debridement group (χ²=4.76, P<0.05). Conclusions: Ultrasound debridement method can significantly reduce the bacterial load of residual burn wounds, reduce postoperative hematoma formation, and promote the survival of skin grafts to shorten the course of disease of patients.

OBJECTIVE: To investigate whether β-globin gene 3'UTR+101G>C (HBB:c.*233G>C) variant has genetic effect and provide basis for gene diagnosis and genetic counseling. METHOD: Whole blood cell analysis and capillary zone electrophoresis (CZE) were used to analyze the hematological indexes. The most frequent 23 mutations in southern Chinese individuals were routinely measured by PCR-flow fluorenscence immunmicrobeads assay. Sanger sequencing was used to detect the other variants of β-globin gene (HBB). RESULTS: In 463 cases, a total of 7 cases with HBB:c.*233G>C variant were detected, among them 4 cases carried other pathogenic variants of HBB gene (2 cases were in trans, 2 cases were in cis), who had typical hematological characteristics of mild β-thalassemia, and 3 cases also carried abnormal hemoglobin variation, but did not have hematological characteristics of β-thalassemia. CONCLUSION The study shows that HBB:c.*233G > C variant has no obvious genetic effect and should be a benign polymorphism.
