ObjectiveTo observe the clinical effectiveness of horticultural therapy involving the planting of Chinese medicinal herbs （mint and lily potted plants） combined with intradermal needling therapy for generalized anxiety disorder （GAD） of liver depression transforming into fire syndrome under transcranial magnetic stimulation and basic psychological therapy， and to explore the possible mechanisms of action. MethodsA total of 180 patients with GAD of liver depression transforming into fire syndrome were randomly divided into three groups， horticultural therapy group， intradermal needling group， and horticultural therapy+intradermal needling group， with 60 patients in each. All groups received basic treatment including basic psychological therapy and transcranial magnetic stimulation. The horticultural therapy group received horticultural therapy in addition to the basic treatment； the intradermal needling group received intradermal needling therapy once a week for 8 weeks in addition to the basic treatment； the horticultural therapy+intradermal needling group received both horticultural therapy and intradermal needling therapy， following the same procedures and duration. Hamilton Anxiety Rating Scale （HAMA）， Self-Rating Anxiety Scale （SAS）， and Pittsburgh Sleep Quality Index （PSQI） scores were assessed at baseline and after 2， 4， 6， and 8 weeks of treatment. Serum levels of adrenocorticotropic hormone （ACTH） and corticosterone （CORT） were measured before treatment and after 8 weeks of treatment. Motor-evoked potential （MEP） baseline levels were recorded before treatment， and MEP amplitude ratios were compared after 1 week and 8 weeks of treatment. Clinical effectiveness and safety were evaluated after 8 weeks of treatment. Pearson correlation analysis was used to examine the relationships between serum ACTH and CORT levels， MEP amplitude， and anxiety. ResultsIn the horticultural therapy group and intradermal needling group， HAMA， SAS and PSQI scores after 4， 6， and 8 weeks treatment were lower than baseline scores （P＜0.05）. In the horticultural therapy+intradermal needling group， these scores showed a significant decline starting after 2 weeks treatment and continuing through 8 weeks after treatment （P＜0.05）. The HAMA， SAS， and PSQI scores in the horticultural therapy+intradermal needling group were significantly lower than those in the other two groups after 2， 4， 6， and 8 weeks treatment （P＜0.05）. After 8 weeks of treatment， serum CORT and ACTH levels in the horticultural therapy+intradermal needling group were significantly lower than baseline levels （P＜0.05） and were also lower than those in the horticultural therapy group and intradermal needling group at the same time point （P＜0.01）. When comparing the level after 8 weeks treatment to that after 1 week treatment， under PAS10 stimulation， the MEP amplitude ratio in the intradermal needling group decreased at 30 minutes， while in the horticultural therapy+intradermal needling group， the MEP amplitude ratio decreased at all time points （P＜0.05 or P＜0.001）； under PAS25 stimulation， the MEP amplitude ratio in the horticultural therapy group increased at 20 minutes， and in the intradermal needle group at 10 minutes （P＜0.05）. In the horticultural therapy+intradermal needling group， the MEP amplitude ratio increased significantly at all time points after treatment （P＜0.001）. The cure rate in the horticultural therapy+intradermal needling group （74.14%， 43/58） was significantly higher than that in the horticultural therapy group （30.00%， 18/60） and the intradermal needling group （48.28%， 28/58， P＜0.05）. Correlation analysis revealed that serum ACTH and CORT levels were positively correlated with HAMA scores （r = 0.488， P＜0.01； r = 0.428， P＜0.01）. Following PAS10 intervention， the MEP amplitude ratio was positively correlated with HAMA scores （r = 0.458， P＜0.01）， whereas after PAS25 intervention， the MEP amplitude ratio was negatively correlated with HAMA scores （r = -0.562， P＜0.01）. ConclusionHorticultural therapy combined with intradermal needling treatment， under transcranial magnetic stimulation and basic psychological therapy， demonstrates significant clinical effectiveness in patients with GAD of liver depression transforming into fire syndrome. Its mechanism of action may be related to the regulation of hyperactivation of the hypothalamic-pituitary-adrenal （HPA） axis and the reduction of cortical excitability.

Objective To explore influencing factors of subsequent fracture among elderly osteoporotic patients and provide a basis for improving the management and early intervention after osteoporotic fracture.Methods A total of 14 349 elderly patients with osteoporotic fracture in 594 hospitals across 31 provinces(autonomous regions and municipalities)were selected by convenience sampling method from September to December 2023.A general information questionnaire and a clinical characteristics of fracture questionnaire were used.The univariate analysis and logistic regression were used to clarify the influencing factors and gender differences.Results A total of 11364 valid questionnaires were collected,with a valid questionnaire recovery rate of 79.20％.Gender,age,occupation,education,marital status,family history of osteoporosis,comorbid osteoarthropathies/rheumatism/ophthalmopathies,bone mineral density,risk of fall,risk of fracture grade,reasons and site for first fracture,whether to use walking aid and receive home rehabilitation guidance were associated with the occurrence of subsequent fracture.Gender comparisons found that widowhood,family history of osteoporosis,comorbid rheumatism,vertebral fracture,alcohol consumption,fall or no causative factor triggering the fracture,and educational level,home rehabilitation instruction were associated with the risk of subsequent fracture only in women(P＜0.05).Smoking was associated with the risk of subsequent fracture only in men(P＜0.05).Conclusion Osteoporotic subsequent fracture in the elderly is affected by multidimensional factors,with significant gender differences.The surveillance of key populations should be strengthened in prevention,control and intervention.

Objective:To analyze the whole genome sequence and key site mutations of hepatitis B virus (HBV) in patients with different stages of disease progression, and to understand the relationship between HBV genetic characteristics and disease progression.Methods:Serum samples and basic information of hepatitis B patients with asymptomatic HBV carrier, chronic hepatitis B patients, cirrhosis patients and primary hepatocellular carcinoma patients were collected. Nested PCR was used to amplify the samples to obtain HBV whole gene sequences. Phylogenetic trees were constructed to determine the genotype of the samples, and gene mutations of the samples were analyzed combined with reference sequences of each type.Results:A total of 256 samples were successfully amplified, including 68 asymptomatic HBV carrier patients, 118 CHB patients, 15 LC patients and 55 HCC patients, and five genotypes (B, C, D, I and C/D) were detected. The result of comparative analysis showed that the mutation rate of 56 nucleotide sites was significantly different among the four groups ( P<0.05). In addition to the discovery of C105T, A1762T/G1764A and G1899A and other previously reported key site mutations, the mutation rates of T53A, C1485T and C1628T in newly diagnosed HCC group were significantly higher than those in other groups, and the mutation rates of T2150G and T2151C in asymptomatic HBV infection group were significantly higher than those in other groups. A total of 26 sequences were deleted, mainly distributed in the pre-C and pre-S regions. The deletion mutation rate in the HCC group was significantly higher than that in the other groups. Conclusions:The data of this study indicate that some nucleotide substitution mutations and deletion mutations may be closely related to the occurrence and development of HBV-related diseases, and HCC patients are more likely to have gene mutations than non-HCC patients. These result provide a reference for understanding the relationship between viral mutation and the progression of HBV infection-related diseases.

Objective To examine the current state of care services for geriatric osteoporotic fractures in Chinese hospitals and to provide a basis for the improvement of these services and the formulation of related policies.Methods In September to November 2023,a stratified convenience sampling method was used to investigate the implementation of care services for elderly patients with osteoporotic fractures in 621 hospitals across 31 provinces(autonomous regions and municipalities)in China.A self-designed questionnaire was utilized for this purpose.Results A total of 621 hospitals participated in the survey,with 432(69.57%)tertiary hospitals and 189(30.43%)secondary hospitals.Over 95%of hospitals provided health education on diet,medication,fall prevention,and early functional exercise for elderly fracture patients.Less than 80%of hospitals provide specialized training on osteoporosis treatment and secondary fracture prevention for medical staff.Only 263 hospitals(42.35%)routinely conduct bone density tests for patients over 50 years old with fractures,while 221 hospitals(35.59%)routinely conduct bone metabolic biochemical tests for such patients.Less than 50%of hospitals provide specialized services,such as geriatric osteoporotic fracture clinics,for elderly patients with osteoporotic fractures.Additionally,39.77%of hospital departments have not developed postoperative care plans for elderly patients with osteoporotic fractures.The lack of specialized care teams(91.63%),insufficient investment in care resources(88.08%),and the absence of policy support(77.45%)are identified as the primary factors impeding the provision of care services for elderly patients with osteoporotic fractures in hospitals.Although some care services in tertiary hospitals are superior to those in secondary hospitals(P<0.05),they are still far from adequate.Conclusion The development of care services for elderly patients with osteoporotic fractures in Chinese hospitals needs improvement.It is recommended to further standardize and enhance the content and methods of health education,intensify clinical assessments related to osteoporosis in elderly fracture patients,improve the professional care capabilities of medical staff,and at the same time,the state should introduce relevant policies to support and promote the construction and development of hospital care services for elderly osteoporotic fracture patients.

Background: Excessive growth of keratinocytes is the critical event in the etiology of psoriasis.However, the underlying molecular mechanism of psoriatic keratinocyte hyperproliferation is still unclear. Objective: This study aimed to figure out the potential contributory role of S-phase kinase-associated protein 2 (SKP2) in promoting the hyperproliferation of keratinocytes in psoriasis. Methods: We analyzed microarray data (GSE41662) to investigate the gene expression of SKP2in psoriatic lesion skins compared with their adjacent non-lesional skin. Then, we further confirmed the mRNA and protein expression of SKP2 in human psoriatic skin tissues, imiquimod (IMQ)-induced psoriatic mice back skins and tumor necrosis factor α (TNF-α), interleukin (IL)-17A and IL-6-stimulated keratinocytes by using real-time quantitative polymerase chain reaction and western blot (WB). Furthermore, we explored the potential pathogenic role and its underlying cellular mechanism of SKP2 in promoting keratinocytes hyperproliferation through 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, cell cycle detection, 5-ethynyl-2′-deoxyuridine staining and WB. Finally, we determined whether inhibition of SKP2 can effectively alleviate the keratinocytes hyperproliferation in vivo. Results: We identified that SKP2 is aberrantly upregulated in the psoriatic lesion skin and cytokines-stimulated keratinocytes. Moreover, upregulated SKP2 augments cytokines-induced keratinocytes hyperproliferation. Mechanistically, enhanced SKP2 increased the S phase ratio through inhibiting Cyclin-Dependent Kinase Inhibitor p27 (P27 Kip1) expression. Correspondingly, suppression of SKP2 with SMIP004 can significantly ease the epidermis hyperplasia in vivo. Conclusion Our results suggest that elevated SKP2 can empower keratinocytes proliferation and psoriasis-like epidermis hyperplasia via downregulation of P27 Kip1. Therefore, targeting SKP2-P27 Kip1 axis might be a promising therapeutic strategy for the treatment of psoriasis in future.

Objective: To assess the efficacy and safety of polymyxin B in neutropenic patients with hematologic disorders who had refractory gram-negative bacterial bloodstream infection. Methods: From August 2021 to July 2022, we retrospectively analyzed neutropenic patients with refractory gram-negative bacterial bloodstream infection who were treated with polymyxin B in the Department of Hematology of the First Affiliated Hospital of the Soochow University between August 2021 to July 2022. The cumulative response rate was then computed. Results: The study included 27 neutropenic patients with refractory gram-negative bacterial bloodstream infections. Polymyxin B therapy was effective in 22 of 27 patients. The median time between the onset of fever and the delivery of polymyxin B was 3 days [interquartile range (IQR) : 2-5]. The median duration of polymyxin B treatment was 7 days (IQR: 5-11). Polymyxin B therapy had a median antipyretic time of 37 h (IQR: 32-70). The incidence of acute renal dysfunction was 14.8% (four out of 27 cases), all classified as "injury" according to RIFLE criteria. The incidence of hyperpigmentation was 59.3%. Conclusion: Polymyxin B is a viable treatment option for granulocytopenia patients with refractory gram-negative bacterial bloodstream infections.

Objective: To investigate the clinical efficacy of allogeneic hematopoietic stem cell transplantation (allo-HSCT) for patients with acute leukemia who are positive for the SET-NUP214 fusion gene (SET-NUP214⁺AL). Methods: This was a retrospective case series study. Clinical data of 18 patients with SET-NUP214⁺AL who received allo-HSCT in the First Affiliated Hospital of Soochow University and Soochow Hongci Hematology Hospital from December 2014 to October 2021 were retrospectively analyzed to investigate treatment efficacy and prognosis. The Kaplan-Meier method was used for survival analysis. Results: Of the 18 patients, 12 were male and 6 were female, and the median age was 29 years (range, 13-55 years). There were six cases of mixed phenotype acute leukemia (three cases of myeloid/T, two cases of B/T, one case of myeloid/B/T), nine cases of acute lymphoblastic leukemia (ALL) (one case of B-ALL and eight cases of T-ALL), and three cases of acute myeloid leukemia. All patients received induction chemotherapy after diagnosis, and 17 patients achieved complete remission (CR) after chemotherapy. All patients subsequently received allo-HSCT. Pre-transplantation status: 15 patients were in the first CR, 1 patient was in the second CR, 1 was in partial remission, and 1 patient did not reach CR. All patients were successfully implanted with stem cells. The median time of granulocyte and platelet reconstitution was +12 and +13 days, respectively. With a median follow-up of 23 (4-80) months, 15 patients survived, while 3 patients died. The cause of death was recurrence of SET-NUP214⁺AL after transplantation. After allo-HSCT, 5 patients relapsed. The estimated 3-year overall survival (OS) and relapse-free survival (RFS) rates were 83.3%±15.2% and 55.4%±20.7%, respectively. Among the 15 patients who achieved CR before transplantation, there was no significant difference in OS and RFS between haploidentical HSCT and matched sibling donor HSCT (all P>0.05). Conclusions: Allo-HSCT can improve the prognosis and long-term survival rate of patients with SET-NUP214⁺AL. Disease recurrence is the most important factor affecting long-term survival.
