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.

Objective:To evaluate the effect of an opioid-sparing anesthesia strategy primarily using quadratus lumborum block combined with esketamine on early postoperative recovery in patients undergoing laparoscopic radical resection of colon cancer.Methods:This study was a randomized controlled trial. From January 2023 to July 2024, 72 patients of either sex, aged 45-65 yr, with body mass index of 18-25 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, undergoing elective laparoscopic radical resection of colon cancer with general anesthesia at Yichang Central People′s Hospital, were divided into 2 groups ( n=36 each) using a random number table method: control group (group C) and opioid-sparing anesthesia strategy group (group D). Anesthesia was induced with sufentanil and propofol and maintained with propofol and remifentanil in group C. In group D, ultrasound-guided quadratus lumborum block was performed before the start of anesthesia, and anesthesia was induced with esketamine, propofol and lidocaine and maintained with esketamine, propofol, low-dose remifentanil, lidocaine and magnesium sulfate. Patient-controlled intravenous analgesia was carried out at the end of surgery until 48 h postoperatively, using dezocine for rescue analgesia. The Quality of Recovery-15 scores were assessed and recorded at 1 day before operation and 1, 3 and 7 days after operation. Ramsay sedation scores were recorded at 2, 6, 12, 24 and 48 h after surgery. The effective pressing times of patient-controlled analgesia and requirement for rescue analgesia were recorded within 24 h after surgery and during the 24-48 h postoperative period. The intraoperative consumption of opioid, emergence time, duration of postanesthesia care unit stay, time to first flatus, first ambulation time and length of postoperative hospital stay were also recorded. The postoperative complications were recorded during hospital stay and assessed with the Clavien-Dindo classification. Results:Compared with group C, the Quality of Recovery-15 scores were significantly increased at each time point after operation, Ramsay sedation scores were increased at 2, 6 and 12 h after operation, the effective pressing times of patient-controlled analgesia and rate of rescue analgesia were decreased in each postoperative period, the intraoperative consumption of remifentanil was reduced, the time to first flatus, first ambulation time and length of postoperative hospital stay were shortened, the incidence of nausea and vomiting was decreased ( P<0.05), and no significant change was found in the emergence time or duration of postanesthesia care unit stay in group D ( P>0.05). Conclusions:The opioid-sparing anesthesia strategy primarily using quadratus lumborum block combined with esketamine can raise the quality of early postoperative recovery in the patients undergoing laparoscopic radical resection of colon cancer.

Objective To evaluate the application value of algal glycolipid nucleic acid-free extraction technology in human papillomaviruses(HPV)nucleic acid of cervical secretions.Methods From July 1 to September 30,2023,50 HPV samples were collected from the 903rd Hospital of PLA,and 12 quality control products of HPV nucleic acid were selected.Samples treated with algal glycolipid nucleic acid-free extraction technology were tested as the experimental group,samples treated with clinical routine detection kit were tested as the control group.The nucleic acid-free extraction technology for HPV detection was assessed for accuracy,sensitivity,precision and the correlation between the two methods.Results The HPV typing results of clinical samples(27 positive samples and 23 negative samples)and quality control products in the experimental group were consistent with those in the control group,with a 100%coincidence rate and high accuracy.The experimental group's detection limit reached 100 copies/ml,demonstrating great sensitivity.The intra-assay coefficient of variations were less than 5%,indicating good precision.The detection results(Ct values)of the two groups showed a strong correlation(P<0.05),and the linear regression equation was Y=2.524+0.901X,r=0.963.There was a good correlation between the Ct values of HPV nucleic acid testing between the experimental group and the control group.Conclusion Algal glycolipid nucleic acid-free extraction technology can be used in clinical cervical secretion HPV nucleic acid detection before treatment,which is suitable for clinical application and promotion.

Objective:To investigate the clinical application value of a novel filter's retraction hook capture technique of pull-assisted method for the endovascular retrieval of conical inferior vena cava (IVC) filters whose hook attached to the wall.Methods:From January 2020 to December 2024, patients with conical filters whose hook attached to the wall admitted at Beijing Jishuitan Hospital were enrolled consecutively.Results:A total of 46 patients underwent filter retrieval using filter's retraction hook capture technique of pull-assisted method. Among these patients, 39 cases (84.8%) were successful in filter retrieval, with the penetration distance of cranial anchor vertex of 3.3(2.5, 4.4) mm, and 13 (33.3%) filters were deformed. The other 7 cases were unsuccessful, with a penetration distance of cranial anchor vertex of 5.0 (4.3, 5.0) mm, and 6 (85.7%) filters were deformed. There was a statistically significant difference between the two groups ( P<0.05). One case (2.2%) had IVC injury, one case (2.2%) experienced filter fracture, and no symptomatic pulmonary embolism occurred. Logistic regression analysis showed that filter deformation was an independent dangerous factor for filter's retraction. Conclusions:Filter's retraction hook capture technique of pull-assisted method is effective in removing conical filters whose hook attached to the wall, with no symptomatic PE occurring. This method can be considered as a new adjuvant technique for filter retrieval.

Objective To explore the protective effects of genetically modified porcine erythrocyte suspension as a subnormothermic normoxic mechanical perfusate on hypoxic-ischemic brain injury in cynomolgus monkeys caused by traumatic hemorrhage.Methods Cynomolgus monkeys were randomly divided into positive and negative control groups(a total of 3 monkeys,with 3 left cerebral hemispheres as the positive control group and 3 right cerebral hemispheres as the negative control group)and the subnormothermic perfusion group(n=3).The positive control group was directly sampled 1 hour after circulatory arrest,while the negative control group was placed at subnormothermic conditions for 6 hours after circulatory arrest.The subnormothermic perfusion group underwent 6 hours of subnormothermic normoxic mechanical perfusion of the bilateral common carotid arteries of the cynomolgus monkey hypoxic-ischemic brain injury model using genetically modified porcine erythrocyte suspension 1 hour after circulatory arrest.Before perfusion,cross-matching experiments were conducted between the six genetically modified pig and the cynomolgus monkeys.After the start of perfusion,the levels of routine blood indicators in the perfusate were detected at 0,1,2,3,4,5 and 6 hours.Blood oxygen saturation was recorded,and the levels of Na+,K+,Ca2+,glucose and blood pH in the perfusate were measured,as well as the levels of IgG and IgM in the perfusate.After 6 hours of perfusion,the water content of the brain tissue was measured.Nissl staining was performed on the frontal cortex and hippocampal regions,and immunofluorescence staining was used to detect the expression of glial fibrillary acidic protein(GFAP),ionized calcium-binding adapter molecule 1(Iba1)and neuronal nuclear antigen(NEUN).Results The cross-matching results between the six genetically modified pig and the cynomolgus monkeys were negative.The number of red blood cells in the perfusate decreased significantly at 3 hours of perfusion,and the hemoglobin level showed a downward trend at 1,3,5 and 6 hours.The number of white blood cells and platelets decreased at all time points.The blood oxygen saturation in the subnormothermic perfusion group remained stable at 95%-98%,and the levels of blood oxygen saturation,Na+,Ca2+,glucose and pH were stable,while the K+level first increased and then decreased.There was no significant difference in the levels of IgG and IgM before and after perfusion.The water content of brain tissue at the end of perfusion in the subnormothermic perfusion group was significantly higher than that in the positive control group(P<0.001).Nissl staining results showed that compared with the positive control group,the pyramidal neurons in the prefrontal cortex of the subnormothermic perfusion group maintained better morphological integrity,with no significant increase in enlarged and deformed cells.In the hippocampal CA1 region,there was a slight increase in enlarged and deformed cells,and a few cells with undamaged structures showed reduced cell size.In the hippocampal dentate gyrus,fewer granule neurons had compromised structural integrity,with increased cell edema.NEUN immunofluorescence staining showed that compared with the positive control group,the pyramidal neurons in the prefrontal cortex and hippocampal CA1 region of the subnormothermic perfusion group had better morphological states,with clear axons.The granule cells in the hippocampal dentate gyrus were well preserved,but the nuclei were less well protected.GFAP immunofluorescence staining showed that compared with the positive control group,the subnormothermic perfusion group had sparser protrusions that were more tightly associated with neurons.Iba1 immunofluorescence staining showed that compared with the positive control group,the subnormothermic perfusion group had thicker and fewer protrusions.Conclusions Compared with the positive control group,subnormothermic normoxic mechanical perfusion with genetically modified porcine erythrocyte perfusate increases brain tissue edema in cynomolgus monkeys,but better preserves the morphological integrity of neurons and glial cells.The protective effects may be related to the continuous oxygen and energy supply,maintenance of ion homeostasis and perfusate pH,reduced rejection,and low metabolic state of the whole brain.

AIM:To compare the effect of AT TORBI 709M and Tecnis ZMT intraocular lenses on astigmatism correction in patients with corneal astigmatism at 3 mo after operation based on the standard astigmatism vector analysis.METHODS: This was a retrospective case-control study. The clinical data of 69 patients(69 eyes)with corneal astigmatism who underwent phacoemulsification and implantation of toric intraocular lens(IOL)from June 2021 to December 2021 in Day Surgery Center of Xi'an No.1 Hospital was analyzed. The patients were divided into two groups. In group one, 38 cases(38 eyes)were implanted with AT TORBI 709M, and 31 patients(31 eyes)with Tecnis ZMT in group two. The axial length, preoperative astigmatism and axis, and the degree of intraocular lens were recorded. The uncorrected distance visual acuity(UCDVA), best corrected distance visual acuity(BCDVA), diopter, residual astigmatism and axis were recorded preoperatively and at 1 wk, 1 and 3 mo postoperatively. The postoperative surgical indicators, including spherical equivalent(SE), target induced astigmatism vector(TIA), surgically induced astigmatism vector(SIA), magnitude of error(ME), absolute value of angle of error(|AE|), absolute value of difference vector(|DV|), correction index(CI), and index of success(IOS)were evaluated by the standard astigmatism vector analysis.RESULTS:Postoperative UCDVA and BCDVA were significantly improved(all P<0.001), and there were statistically significant differences compared to preoperative UCDVA and BCDVA(all P<0.001). While, there was no significant difference in UCDVA and BCDVA between the two groups(P=0.275, 0.124). The standard astigmatism vector analysis showed that a good astigmatism correction was achieved in both AT TORBI 709M group and Tecnis ZMT group, and both |DV| and IOS were close to 0(P=0.329, 0.288). The CI of the AT TORBI 709M group was closer to 1, indicating a better astigmatism correction, while the CI of the Tecnis ZMT group was higher than 1, suggesting an overcorrection of astigmatism. However, the difference between the two groups was not statistically significant(P=0.193). The mean residual astigmatism at 3 mo postoperatively was -0.11±0.91 D in the AT TORBI 709M group and -0.46±0.76 D in the Tecnis ZMT group, respectively, showing no statistically significance difference(t=1.732, P=0.088).CONCLUSION:Both the flat loop AT TORBI 709M and the double C-loop Tecnis ZMT intraocular lenses can effectively improve postoperative visual acuity in patients with regular corneal astigmatism, showing good rotational stability and comparable correction abilities for both astigmatism with the rule and against-the-rule astigmatism.

Objective To investigate the protective effects of secretomes released by three-dimensional cultured mesenchymal stem cells(MSCs)on neurons subjected to seawater immersion(SW)and stretch injury(SI),and to provide new insights into neuronal repair following SW combined with traumatic brain injury(TBI).Methods MSCs were cultured using the hanging drop method,and the conditioned medium(CM)containing MSCs secretomes was collected.A cellular model combining SW with SI was established using mouse hippocampal neuronal cells(HT22 cells).HT22 cells were randomly assigned to five groups:control,SI,SI+SW,SI+CM,and SI+SW+CM groups.Cell viability was assessed using the CCK-8 assay,apoptosis rate was measured by flow cytometry,cell migration ability was evaluated by scratch assay,and the expression levels of apoptosis-related proteins Bcl-2 and Bcl-2-associated protein(Bax),and ferroptosis-related proteins long-chain acyl-CoA synthetase 4(ACSL4)and cyclooxygenase-2(COX-2)were detected by Western blotting.Results Immersion in 15%seawater for 12 h significantly decreased HT22 cell viability(P<0.05).The CCK-8 assay indicated that cell viability in both the SI and SI+SW groups was significantly lower than that in control group after 12 h of treatment(P<0.05).Treatment with CM containing MSCs secretomes significantly increased cell viability in SI+CM group compared to SI group(P<0.0001),and in SI+SW+CM group compared to SI+SW group(P<0.001).Flow cytometry results revealed that the apoptosis rate in SI and SI+SW groups was significantly higher than that in control group(P<0.05 or P<0.001),while in SI+CM group was lower than that in SI group(P<0.05),and in SI+SW+CM group was lower than that in SI+SW group(P<0.05).Western blotting showed that compared to control group,SI and SI+SW groups exhibited reduced Bcl-2 expression level(P<0.01 or P<0.0001)and increased expression levels of Bax,ACSL4,and COX-2(P<0.01 or P<0.0001).Compared to SI group,the SI+CM group displayed increased Bcl-2 expression level(P<0.05)and decreased expression levels of Bax,ACSL4,and COX-2(P<0.05).Compared to SI+SW group,SI+SW+CM group exhibited increased Bcl-2 expression level(P<0.01)and decreased expression levels of Bax,ACSL4,and COX-2(P<0.01 or P<0.001).Scratch assay results demonstrated that at both 12 h and 24 h,the cell migration rate in SI and SI+SW groups was significantly lower than that in control group(P<0.01 or P<0.0001),while the migration rate in SI+CM group was significantly higher than that in SI group(P<0.0001 or P<0.01),and the migration rate in SI+SW+CM group was significantly higher than that in SI+SW group(P<0.0001).Conclusion Secretomes derived from MSCs cultured using the hanging drop method can alleviate neuronal damage caused by SW and TBI,potentially offering a therapeutic approach for SW combined with TBI.

Objective To investigate the protective effect of Gynostemma pentaphyllum on memory of individuals rapidly ascending to high altitudes.Methods Twenty-one healthy subjects were randomly divided into a G.pentaphyllum food group(n=12)and a control group(n=9).The first group consumed G.pentaphyllum food for seven consecutive days while the control group received placebos.Both groups ascended from the plains to an altitude of 3600 m.Memory function was assessed using the matching memory and sequential memory tests of a cognitive evaluation system on day 1 and day 7 on the plains,and at 24 and 48 h after ascending to the high altitude.Scores of acute mountain sickness symptoms were also recorded.Results After 24 h of stay at the high altitude,the score of headache of the G.pentaphyllum food group was significantly lower than that of the control group(P＜0.05).Cognitive test results showed that the matching memory accuracy and sequential memory accuracy of the control group at 24 and 48 h were significantly lower than those on the plains(P＜0.05).In contrast,the G.pentaphyllum food group performed significantly better than the control group in these metrics(P＜0.05).Conclusion Regular consumption of G.pentaphyllum food can effectively alleviate headache symptoms in individuals rapidly ascending to high altitudes and mitigate the decline in working memory,short-term memory,and memory spans caused by acute hypoxic exposure.

Left ventricular assist device (LVAD) serves as a critical therapeutic option for patients with end-stage heart failure, significantly enhancing survival rates and quality of life. However, LVAD implantation exerts complex and profound effects on right ventricular (RV) function, with RV dysfunction emerging as a key factor influencing the prognosis of LVAD patients. This article systematically reviews the relationship between LVAD and RV function, exploring the importance of RV function in LVAD patients, assessment methods, underlying mechanisms of impact, and strategies for prevention and management. Comprehensive evidence suggests that preoperative evaluation of RV function is crucial for predicting the risk of RV dysfunction, while effective prevention and management rely on preoperative optimization, meticulous intraoperative techniques, rigorous postoperative monitoring, and multidisciplinary collaboration. Furthermore, this review discusses the potential and future directions of emerging technologies, such as improved LVAD designs, biventricular assist devices, gene therapy, and personalized medicine, in ameliorating RV dysfunction. In conclusion, RV function is one of the key determinants of successful LVAD therapy. Through comprehensive assessment, prevention, and management of RV function, coupled with the application of novel technologies, the clinical outcomes of LVAD patients can be further improved.
