ObjectiveTo analyze the epidemiological features and influencing factors of rabies in Shanxi Province，and to provide evidence to further promote the elimination of rabies in Shanxi Province. MethodsThe incidence data of rabies in Shanxi from 2011 to 2022 were collected and subjected to descriptive analysis. ResultsFrom 2011 to 2022， a total of 348 rabies cases were reported in Shanxi Province， with an average annual incidence of 0.080 3/10⁵. The incidence of rabies showed a downward trend overall. The highest incidence was in August. The cases were mainly farmers， mostly males， and most cases were reported between 50 and 69 years old. The data of cases showed that dogs were the main animals attacking human （93.96%）. The incubation period of most cases was 1‒3 months （37.37%）.The main exposure site was hand（51.33%）. Only 2.66% cases with grade Ⅲ exposure were injected with passive immune agents. ConclusionThe incidence of rabies in Shanxi Province continues to decrease， but there are still loopholes in prevention and control measures. It is necessary to strengthen the management and immunization of dogs，health education， and standardized procedures after exposure to maintain the achievements in the prevention and control of rabies.

Objective:To investigate the role of RNA m6A methylation in mediating cerebellar dysplasia through analyzing the phenotypes of the mouse cerebella and the expression of several key m6A regulators upon hypobaric hypoxia treatment.Methods:Five-day old C57/BL6 mice were exposed to hypobaric hypoxia for 9 days. The status of mouse cerebellar development was analyzed by comparing the body weights, brain weights and histological features. Immunostaining of cell-type-specific markers was performed to analyze the cerebellar morphology. Real-time PCR, Western blot and immunohistochemical staining were performed to detect the expression of key m6A regulators in the mouse cerebella.Results:Compared with the control, the body weights, brain weights and cerebellar volumes of hypobaric hypoxic mice were significantly reduced ( P<0.01). The expression of specific markers in different cells, including NeuN (mature neuron), Calbindin-D28K (Purkinje cell) and GFAP (astrocyte), was decreased in hypobaric hypoxic mouse cerebella ( P<0.01), accompanied with disorganized cellular structure. The expression of methyltransferase METTL3 was significantly down-regulated in the cerebella of hypobaric hypoxic mice ( P<0.05). Conclusions:Hypobaric hypoxia stimulation causes mouse cerebellar dysplasia, with structural abnormalities in mature granular neurons, Purkinje cells and astrocytes. Expression of METTL3 is decreased in hypobaric hypoxic mice cerebellum compared with that of normobaric normoxic mice, suggesting that its mediated RNA m6A methylation may play an important role in hypobaric hypoxia-induced mouse cerebellar dysplasia.

Objective:To analyze the changing trends of the epidemic characteristics of human brucellosis in Hangzhou City, and to provide a basis for further formulating prevention and control measures.Methods:The epidemic data of brucellosis in Hangzhou City from 2004 to 2021 were collected from the "China Disease Control and Prevention Information System" and the annual reports, compilations and summaries of prevention and control work of brucellosis in Hangzhou City, and the epidemiological characteristics and trends of brucellosis cases in Hangzhou City from 2004 to 2009, 2010 to 2015, and 2016 to 2021 were compared and analyzed.Results:A total of 186 cases of brucellosis were diagnosed in Hangzhou City from 2004 to 2021, with an average annual incidence rate of 0.151/100 000, ranging from 0.016/100 000 to 0.286/100 000. The incidence rate showed a stage-by-stage upward trend from 2004 to 2009, 2010 to 2015, and 2016 to 2021 ( Z = 3.15, P = 0.002). The age of onset of brucellosis cases was predominantly 18 - 60 years old, accounting for 78.49% (146/186). The male-to-female ratio was 2.10∶1.00 (126∶60). The occupational and non-occupational populations accounted for 62.90% (117/186) and 37.10% (69/186), respectively, with the proportion of non-occupational cases in the three stages being 28.57%, 23.29% and 51.76%, showing an increasing trend (χ 2trend = 9.85, P = 0.002). The regional distribution was dominated by Yuhang District, accounting for 55.91% (104/186), followed by Jianggan District (9.14%, 17/186) and Fuyang District (7.53%, 14/186). The number of brucellosis epidemic counties (cities, districts) increased from 6 to 9. The seasonal analysis showed that the proportion of cases from January to June decreased from 84.93% (23/28) from 2004 to 2009 to 54.12% (46/85) from 2016 to 2021. The proportion of infection from outside the province in the three stages was 0, 10.96% and 27.38%, respectively, showing an upward trend (χ 2trend = 18.16, P < 0.001), the main infected areas were Henan Province, Heilongjiang Province, and Inner Mongolia Autonomous Region. In clinical symptoms and signs, the incidence of muscle and joint pain and low back pain increased from 60.71% (17/28) and 10.71% (3/28) from 2004 to 2009, respectively, to 83.53% (71/85) and 25.88% (22/85) from 2016 to 2021, both showing an upward trend (χ 2trend = 9.92, 4.67, P = 0.002, 0.031). Conclusions:The incidence of human brucellosis in Hangzhou City is on the rise, and the number of cases of non-occupational population has increased significantly in recent years. The sheep breeding places have gradually become the high incidence areas of brucellosis in Hangzhou City. It is recommended to strengthen the promotion and education of knowledge on brucellosis prevention among the general public, and focus on actively monitoring human brucellosis in high-risk areas.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Background/Aims: Total proctocolectomy with ileal pouch-anal anastomosis (IPAA) is widely accepted as a radical surgery for refractory ulcerative colitis (UC). Definite results on the appropriate pouch length for an evaluation of the risk-to-benefit ratio regarding technical complications and long-term quality of life (QOL) are still scarce. Methods: Data on UC patients who underwent IPAA from 2008 to 2022 in four well-established pouch centers affiliated to China UC Pouch Center Union were collected. Results: A total of 208 patients with a median follow-up time of 6.0 years (interquartile range, 2.3 to 9.0 years) were enrolled. The median lengths of the patients’ short and long pouches were 14.0 cm (interquartile range, 14.0 to 15.0 cm) and 22.0 cm (interquartile range, 20.0 to 24.0 cm), respectively. Patients with a short J pouch configuration were less likely to achieve significantly improved long-term QOL (p=0.015) and were prone to develop late postoperative complications (p=0.042), such as increased defecation frequency (p=0.003) and pouchitis (p=0.035). A short ileal pouch was an independent risk factor for the development of late postoperative complications (odds ratio, 3.100; 95% confidence interval, 1.519 to 6.329; p=0.002) and impaired longterm QOL improvement (odds ratio, 2.221; 95% confidence interval, 1.218 to 4.050, p=0.009). Conclusions The length of the J pouch was associated with the improvement in long-term QOL and the development of late post-IPAA complications. A long J pouch configuration could be a considerable surgical option for pouch construction.

Central nervous system （CNS） is a sophisticated system subject to complex regulation， which dominates the high-level neural activities of the human body. Due to its complex physiological structure and refined regulatory mechanism covering a variety of diseases， CNS is the place where many chronic， refractory and rare diseases occur. Nerve cell is the basic unit of CNS， and its dysfunction and death is the root cause of CNS diseases. Ferroptosis is a new form of programmed cell death proposed in recent years， and has been proved to be closely related to the production and development of multiple CNS diseases. Traditional Chinese medicine （TCM）， including Chinese herbs， acupuncture and moxibustion， and massage， has shown unique advantages in the treatment of CNS diseases for a long time. A large number of studies have demonstrated that TCM participates in the regulation of CNS diseases via regulating ferroptosis and shows a good research prospect. This paper summarized the characteristics of ferroptosis and discussed the association between ferroptosis and CNS diseases in pathological mechanism. We also reviewed the regulation of various CNS diseases by different TCM interventions through ferroptosis， providing references for TCM to participate in the treatment of CNS diseases properly in the future.

Objective:To explore the clinical efficacy of modern rehabilitation techniques combined with Traditional Chinese Medicine (TCM) external application in the treatment of knee stiffness.Methods:Prospective cohort study. A total of 80 patients with knee stiffness meeting the entry criteria admitted to the People's Hospital of Bozhou from January 2019 to December 2021 were selected and divided into the observation group ( n=40) and the control group ( n=40) according to the random ball touching method. Both groups were given routine physiotherapy. The control group was treated with TCM external application on the basis of the physiotherapy, and the observation was treated with modern rehabilitation techniques on the basis of the treatment of the control group. The goniometer was used to measure the knee flexion and extension before and after treatment, and the VAS scale was used to assess the knee pain. Fug l-Meyer motor function score was used to evaluate lower extremity motor function. Results:After treatment, the knee flexion [(96.43 ± 4.63) ° vs. (89.58 ± 4.67) °, t=6.59] in the observation group was higher than that of the control group ( P<0.01), and the extension [(8.32 ± 2.03) ° vs. (11.69 ± 2.37) °, t=6.83] in the control group was lower than that of the control group ( P<0.01); VAS score (2.06 ± 0.49 vs. 3.65 ± 0.76, t=11.12) was lower than that of the control group ( P<0.01), and Fugl Meyer motor function score (28.97 ± 3.76 vs. 20.43 ± 3.04, t=11.17) was higher than that of the control group ( P<0.01). Conclusion:The application of modern rehabilitation techniques combined with TCM external application in the treatment of knee stiffness can improve the range of motion of the knee joint, reduce the VAS score of pain, and improve the motor function.

Stroma surrounding the tumor cells plays crucial roles for tumor progression. However, little is known about the factors that maintain the symbiosis between stroma and tumor cells. In this study, we found that the transcriptional regulator-signal transducer and activator of transcription 3 (Stat3) was frequently activated in cancer-associated fibroblasts (CAFs), which was a potent facilitator of tumor malignancy, and formed forward feedback loop with platelet-activating factor receptor (PAFR) both in CAFs and tumor cells. Importantly, PAFR/Stat3 axis connected intercellular signaling crosstalk between CAFs and cancer cells and drove mutual transcriptional programming of these two types of cells. Two central Stat3-related cytokine signaling molecules-interleukin 6 (IL-6) and IL-11 played the critical role in the process of PAFR/Stat3 axis-mediated communication between tumor and CAFs. Pharmacological inhibition of PAFR and Stat3 activities effectively reduced tumor progression using CAFs/tumor co-culture xenograft model. Our study reveals that PAFR/Stat3 axis enhances the interaction between tumor and its associated stroma and suggests that targeting this axis can be an effective therapeutic strategy against tumor malignancy.
