ObjectiveTo investigate the present situation of input, output, outcome and impact of all registered community-based rehabilitation stations in Inner Mongolia in China, and analyze how the input predict the output, outcome and impact. MethodsFrom March 1st to April 30th, 2025, a questionnaire survey was conducted on all registered community-based rehabilitation stations in Inner Mongolia, covering four dimensions: input, output, outcome and impact. A total of 1 365 questionnaires were distributed. The input included four items: laws and policies, human resources, equipment and facilities, and rehabilitation information management. The output included two items: technical paths and benefits/effectiveness. The outcome included three items: coverage rates, rehabilitation interventions and functional results. The impact included two items: health and sustainability. Each item contained several questions, all of which were described in a positive way. Each question was scored from one to five. A lower score indicated that the situation of the community-based rehabilitation station was more in line with the content described in the question. Regression analysis was performed using the total score of each item of input dimension as independent variables, and the total scores of the output, outcome and impact dimensions as dependent variables. ResultsA total of 1 262 valid questionnaires were collected. The mean values of input, output, outcome and impact of community-based rehabilitation stations were 1.827 to 1.904, with coefficient of variation of 45.892% to 49.239%. The regression analysis showed that, rehabilitation information management, human resources, and laws and policies significantly predicted the output dimension (R² = 0.910, P < 0.001). Meanwhile, all four items in the input dimension predicted both the outcome (R² = 0.850, P < 0.001) and impact dimensions (R² = 0.833, P < 0.001). ConclusionInput, output, outcome and impact of the community-based rehabilitation stations in Inner Mongolia were generally in line with the content of the questions, although some imbalances were observed. Additionally, the input of community-based rehabilitation stations could significantly predict their output, outcome and impact.

ObjectiveTo collate and compare the characteristics and differences in the methods for constructing animal models of different subtypes of gastroesophageal reflux disease （GERD） based on literature， providing a reference for researchers in this field regarding animal model construction. MethodsExperimental studies related to GERD including reflux esophagitis （RE）， nonerosive reflux disease （NERD） and Barrett's esophagus （BE） model construction from January 1， 2014 to January 27， 2024， were retrieved from databases such as CNKI， Wanfang， VIP， Web of Science， and Pubmed. Information on animal strains， genders， modeling methods including disease-syndrome combination models， modeling cycles were extracted； for studies with model evaluation， the methods of model evaluation were also extracted； then analyzing all those information. ResultsA total of 182 articles were included. SD rats were most frequently selected when inducing animal models of RE （88/148， 59.46%） and NERD （9/14， 64.29%）. For BE， C57BL/6 mice were most commonly used （11/20， 55.00%）. Male animals （RE： 111/135， 82.22%； NERD： 11/14， 78.57%； BE： 10/12， 83.33%） were the most common gender among the three subtypes. The key to constructing RE animal models lies in structural damage to the esophageal mucosal layer， gastric content reflux， or mixed reflux， among which forestomach ligation + incomplete pylorus ligation （42/158， 26.58%） was the most common modeling method； the key to constructing NERD animal models lies in micro-inflammation of the esophageal mucosa， visceral hypersensitivity， and emotional problems， and intraperitoneal injection of a mixed suspension of ovalbumin and aluminum hydroxide combined with acid perfusion in the lower esophagus （8/14， 57.14%） was the most common modeling method； the key to constructing BE animal models lies in long-term inflammatory stimulation of the esophageal mucosa and bile acid reflux， and constructing interleukin 2-interleukin 1β transgenic mice （7/25， 28.00%） was the most common modeling method. Adverse psychological stress was the most common method for inducing liver depression. ConclusionsThe construction key principles and methodologies for RE， NERD， and BE animal models exhibit significant differences. Researchers should select appropriate models based on subtype characteristics （e.g.， RE focusing on structural damage， NERD emphasizing visceral hypersensitivity）. Current studies show insufficient exploration of traditional Chinese medicine disease-syndrome combination models. Future research needs to optimize syndrome modeling approaches （e.g.， composite etiology simulation） and establish integrated Chinese-Western medicine evaluation systems to better support mechanistic investigations of traditional Chinese medicine.

Objective:To evaluate the efficacy and safety of endoscopic variceal ligation (EVL) of esophageal varices combined with endoscopic variceal intensive ligation (EVIL) of gastric varices for gastroesophageal variceal bleeding with liver cirrhosis under non-emergency settings.Methods:Data of 643 consecutive patients with gastroesophageal variceal bleeding due to liver cirrhosis admitted to the Department of Gastroenterology, Henan Provincial People's Hospital from January 2017 to March 2023 were included in the retrospective study. A total of 192 patients were included after excluding 451 patients. One hundred and forty-nine patients who underwent EVL of esophageal varices combined with EVIL of gastric varices were enrolled into the EVIL group, while 43 patients who underwent EVL of esophageal varices combined with endoscopic tissue adhesive injection (ETAI) of gastric varices were enrolled into the ETAI group. The endoscopic treatment success rate, esophageal variceal ligations number, operation time of endoscopic treatment, hospitalization time, rebleeding rate, mortality and the incidence of adverse events were compared between the two groups.Results:Compared with the ETAI group, the EVIL group exhibited significantly higher endoscopic treatment success rate [100.0% (149/149) VS 95.3% (41/43), P=0.049], slightly greater esophageal variceal ligations number [8 (6, 11) rings VS 7 (6, 9) rings, Z=-1.29, P=0.196], shorter operation time of endoscopic treatment [27.0 (20.5, 34.0) min VS 36.0 (21.0, 51.0) min, Z=-2.30, P=0.021], and significantly shorter hospitalization time [10 (7, 13) d VS 13 (9, 15) d, Z=-3.02, P=0.003]. The rebleeding rate within 24, 72, 120 hours after the operation, early, delayed and total rebleeding in the EVIL group were 0.0% (0/149), 0.0% (0/149), 0.7% (1/149), 2.0% (3/149), 12.8% (19/149) and 14.8% (22/149) respectively, and 4.7% (2/43) ( P=0.049), 9.3% (4/43) ( P=0.002), 9.3% (4/43) ( χ2=6.69, P=0.010), 4.7% (2/43) ( χ2=0.17, P=0.679), 30.2% (13/43) ( χ2=7.34, P=0.007) and 44.2% (19/43) ( χ2=17.20, P<0.001) in the ETAI group, respectively. No death related to rebleeding occurred within 6 weeks after the operation in 2 groups. The mortality related to rebleeding within 1 year after the operation and during the follow-up period in the EVIL group were 1.3% (2/149) and 3.4% (5/149) respectively, and 0.0% (0/43) ( P=1.000) and 2.3% (1/43) ( χ2=0.02, P=0.876) in the ETAI group, respectively. The incidences of fever, chest pain, nausea or vomiting in the EVIL group were 12.1% (18/149), 14.1% (21/149) and 13.4% (20/149) respectively, and 11.6% (5/43) ( χ2=0.01, P=0.936), 16.3% (7/43) ( χ2=0.13, P=0.721) and 18.6% (8/43) ( χ2=0.72, P=0.396) in the ETAI group, respectively. Two patients (1.3%) in the EVIL group had gastric variceal ring loss. Ectopic embolism occurred in 1 patient (2.3%) in the ETAI group. Conclusion:For patients with gastroesophageal variceal bleeding due to liver cirrhosis who are suitable for non-emergency endoscopic treatment, EVL of esophageal varices combined with EVIL of gastric varices is also safe, and more effective than EVL of esophageal varices combined with ETAI of gastric varices. This approach offers improved treatment success rate, reduced operation and hospitalization time, lower rebleeding rates, and decreased rebleeding-related mortality.

Objective:To compare the efficacy of saline irrigation following mesh basket lithotripsy and mesh basket combined with balloon lithotripsy for choledocholithiasis.Methods:Data of 76 patients who received endoscopic retrograde cholangiopancreatography (ERCP) for choledocholithiasis in Henan Provincial People's Hospital from May 2021 to May 2023 were retrospectively analyzed. Among them, 30 patients underwent saline irrigation of the biliary tract after mesh basket lithotripsy (the saline group), while 46 patients underwent mesh basket combined with balloon lithotripsy (the balloon group). The procedure success rate, operation time, procedure cost, and incidence of postoperative complications were compared.Results:The stone extraction success rates were 100.0% in both groups. The operation time in the saline group was shorter than that in the balloon group [20.0 (16.0, 27.5) min VS 29.0 (22.0, 33.3) min, Z=-2.88 , P=0.004]. The procedure cost in the saline group was lower than that in the balloon group [13 466.5 (13 318.0, 13 784.0) yuan VS 16 209.0 (15 989.0, 16 327.8) yuan, Z=-6.37 , P<0.001]. There was no significant difference in the incidence of postoperative fever, cholangitis or pancreatitis between the two groups ( P>0.05). Conclusion:Compared with mesh basket combined with balloon lithotripsy, saline irrigation of the biliary tract after mesh basket lithotripsy can shorten the operation time, reduce the procedure cost, and maintain a high procedure success rate for treating choledocholithiasis.

Objective:To relate the changes in electroencephalography (EEG) signals after a spinal cord injury (SCI) with functional independence.Methods:The EEG data describing ninety SCI patients in both open and closed eye states were compared with those collected from 45 healthy counterparts. The SCI patients′ EEG data were correlated with their spinal cord independence measure (SCIM) scores at corresponding time points. The SCI patients were divided into a cervical SCI group (SCI-C group) and a non-cervical SCI group (SCI-NC group), with 45 cases in each group. The difference in EEG data between them and its correlation with the SCIM scores were also compared and analyzed.Results:In the eyes-open state, the EEG power in the frontal, central, temporal, and right occipital regions of the SCI group was lower than among the control group, on average. There were significant differences in the δ and θ low-frequency bands. The α1 band power in the frontal and right parietal regions was significantly higher in the SCI group, on average. With the eyes closed the δ band power in the right prefrontal, frontal, left central, and temporal regions of the SCI group was lower than among the control group, while the α1 band power in the right prefrontal, frontal, central, and parietal regions was significantly higher. The reactivity to eye opening of the α1 band in the right prefrontal, frontal, central, parietal, and temporal regions was less in the SCI patients compared to healthy subjects. Among the SCI patients, higher EEG power in the β2 band of the right frontal lobe and the α2 and β bands of the right temporal lobe was significantly positively correlated with higher SCIM scores during the eyes-open measurements. And the higher EEG power in the α2 band of the prefrontal and frontal lobes, the β2 band of the frontal lobe, the α2 band of the right central region, the α2 and β bands of the temporal lobe, and the α2 and β2 bands of the occipital lobe was significantly positively correlated with higher SCIM scores during the eyes-closed state. The subgroup analysis showed that the δ band power in the left temporal lobe and the α2 band power in the parietal lobe were lower among the SCI-C compared with the SCI-NC patients in the eyes-open state. With the eyes closed, the δ band power in the left frontal, left parietal, and left temporal lobes and the α2 band power in the frontal, central, parietal, temporal, and right occipital lobes was significantly lower in the SCI-C group compared to the SCI-NC group, on average. The reactivity to eye opening of the δ band in the temporal lobe, the α2 band in the left prefrontal, frontal, central, parietal, temporal, and right occipital lobes, and the β2 band in the right parietal and left occipital lobes was less in the SCI-C group than in the SCI-NC group ( P≤0.05). Among the SCI-C patients, higher EEG power in the β1 and β2 bands of the right temporal lobe with the eyes open was significantly positively correlated with higher SCIM scores. With the eyes closed, higher EEG power in the α2 and β1 bands of the right prefrontal lobe was significantly positively correlated with higher SCIM scores. Among the SCI-NC patients, higher EEG power in the δ band of the prefrontal lobe, the β1 and β2 bands of the left prefrontal lobe, and the δ bands of the frontal, central, right parietal, and right temporal lobes during the eyes open measurements was significantly positively correlated with higher SCIM scores. Conclusions:The EEG power of cervical and non-cervical SCI patients shows characteristic changes which correlate with their functional independence.

Objective:To understand the prevalence of frailty and the importance of its influencing factors in adult population in Shaanxi Province.Methods:The data were from Shaanxi baseline survey of natural population cohort study in northwest China during 2018-2019. The frailty index (FI) was constructed to evaluate the frailty status of the population, and XGboost model combined with Shapley method was used to analyze the importance of the sociodemographic and life behavior factors affecting the prevalence of frailty by gender and age.Results:A total of 25 079 subjects were included, in whom 964 (3.8%) had frailty, and there was no significant difference in the overall prevalence of frailty between women (3.9%) and men (3.8%) ( P=0.629), but there was a gender specific difference in the distribution of FI ( P<0.001), and the proportion of the pre-frailty in men was higher than that in women. The prevalence of frailty increased with age ( P<0.001), the prevalence of frailty were 1.3%, 2.5% and 7.8% in young, middle-aged and elderly women, respectively, and 1.9%, 2.7% and 5.5% in young, middle-aged and elderly men, respectively. Sociodemographic characteristics and lifestyle patterns were both influencing factors for the prevalence of frailty, but their importance varied with gender and age. The top five contributing factors were education level, staying up late, annual family income level, sedentary time and marital status in young women, and staying up late, smoking, annual family income level, sedentary time and drinking in young men. The top five contributing factors were education level, annual family income level, passive exposure to smoking, staying up late, and sedentary time in middle-aged women, and annual family income level, education level, sedentary time, staying up late and drinking in middle-aged men. The top five contributing factors were annual family income level, passive exposure to smoking, sedentary time, marital status, and smartphone use in elderly women, and education level, annual family income level, smoking, smartphone use and sedentary time in elderly men. Conclusions:There are gender specific differences in the distribution of FI in Shaanxi. The prevalence of frailty increased with age, but young and middle-aged people also have frailty risk. The prevalence of frailty in young men was mainly related to unhealthy life behaviors, such as staying up late, smoking, sedentary behavior and drinking, while the prevalence of frailty in middle-aged and elderly men and women were more affected by sociodemographic factors, such as education level, economic status and marital status.

Objective To explore the application value of musculoskeletal ultrasound(MSUS)in grading acute gastrocnemius muscle injuries.Methods A retrospective analysis was conducted on ultrasound images of 291 patients who presented with sudden calf pain and suspected acute gastrocnemius muscle injury in the General Hospital of Central Theater Command from March 2019 to July 2024.The images were independently reviewed and assessed by three ultrasound doctors with different qualifications to determine the presence and grade of gastrocnemius muscle injury.The consistency of grading results among three doctors was compared.The diagnostic results of three doctors were summarized.Then,the diagnostic results of 29 patients who underwent routine MRI scans were compared with those of MSUS,and the agreement between the two imaging modalities was assessed using the Kappa test.Results Among the 291 patients,171 cases(58.8%)were diagnosed with gastrocnemius muscle injury,including 55 cases(32.2%)with grade Ⅰ,109 cases(63.7%)with grade Ⅱ,and 7 cases(4.1%)with grade Ⅲ.There were 159 cases(93.0%)of unilateral medial head injury,10 cases(5.8%)of unilateral lateral head injury,and 2 cases(1.2%)of bilateral medial and lateral head injury.Compared with patients without gastrocnemius muscle injury,patients with gastrocnemius muscle injury were older(P<0.05),with no significant difference in gender and laterality(P>0.05).No significant differences in baseline characteristics were found among patients with different grades of injury(P>0.05).The three doctors diagnosed 173(59.5%),171(58.8%),and 171(58.8%)cases of injury,respectively,with an inter-class correlation coefficient(ICC)of 0.947(P<0.001).Among 29 patients who underwent MRI,the diagnostic agreement between MRI and ultrasound for grade Ⅰ,Ⅱ and Ⅲ injury was 8(27.6%),18(62.1%)and 3(10.3%)for MRI;and 9(31.0%),17(58.6%)and 3(10.3%)for MSUS,respectively,with a Kappa value of 0.808(P<0.001).Conclusions MSUS is effective for assessing the grade of acute gastrocnemius muscle injury,and shows high diagnostic consistency among doctors with different qualifications.It is recommended as the preferred method for diagnosing gastrocnemius muscle injury.

Triple-negative breast cancer (TNBC) represents a distinctive subtype, characterized by the absence of estrogen receptors, progesterone receptors, and human epidermal growth factor receptor 2 (HER2). Due to its high inter-tumor and intra-tumor heterogeneity, TNBC poses significant chanllenges for personalized diagnosis and treatment. The advant of clustered regular interspaced short palindromic repeats (CRISPR) technology has profoundly enhanced our understanding of the structure and function of the TNBC genome, providing a powerful tool for investigating the occurrence and development of diseases. This review focuses on the application of CRISPR/Cas technology in the personalized diagnosis and treatment of TNBC. We begin by discussing the unique attributes of TNBC and the limitations of current diagnostic and treatment approaches: conventional diagnostic methods provide limited insights into TNBC, while traditional chemotherapy drugs are often associated with low efficacy and severe side effects. The CRISPR/Cas system, which activates Cas enzymes through complementary guide RNAs (gRNAs) to selectively degrade specific nucleic acids, has emerged as a robust tool for TNBC research. This technology enables precise gene editing, allowing for a deeper understanding of TNBC heterogeneity by marking and tracking diverse cell clones. Additionally, CRISPR facilitates high-throughput screening to promptly identify genes involved in TNBC growth, metastasis, and drug resistance, thus revealing new therapeutic targets and strategies. In TNBC diagnostics, CRISPR/Cas was applied to develop molecular diagnostic systems based on Cas9, Cas12, and Cas13, each employing distinct detection principles. These systems can sensitively and specifically detect a variety of TNBC biomarkers, including cell-specific DNA/RNA and circulating tumor DNA (ctDNA). In the realm of precision therapy, CRISPR/Cas has been utilized to identify key genes implicated in TNBC progression and treatment resistance. CRISPR-based screening has uncovered potential therapeutic targets, while its gene-editing capabilities have facilitated the development of combination therapies with traditional chemotherapy drugs, enhancing their efficacy. Despite its promise, the clinical translation of CRISPR/Cas technology remains in its early stages. Several clinical trials are underway to assess its safety and efficacy in the treatment of various genetic diseases and cancers. Challenges such as off-target effects, editing efficiency, and delivery methods remain to be addressed. The integration of CRISPR/Cas with other technologies, such as 3D cell culture systems, human induced pluripotent stem cells (hiPSCs), and artificial intelligence (AI), is expected to further advance precision medicine for TNBC. These technological convergences can offer deeper insights into disease mechanisms and facilitate the development of personalized treatment strategies. In conclusion, the CRISPR/Cas system holds immense potential in the precise diagnosis and treatment of TNBC. As the technology progresses and becomes more costs-effective, its clinical relevance will grow, and the translation of CRISPR/Cas system data into clinical applications will pave the way for optimal diagnosis and treatment strategies for TNBC patients. However, technical hurdles and ethical considerations require ongoing research and regulation to ensure safety and efficacy.
