Objective:To evaluate the clinical effect of hemostatic air cushion with exhaust control valve for compression hemostasis after hemodialysis.Methods:From May to October 2019, 50 patients with autogenous arteriovenous fistula who underwent regular hemodialysis in the blood purification center of the first hospital of Jilin University were selected and randomly divided into two groups. After dialysis, self-made hemostatic air cushion with exhaust adjustment (experimental group) and gauze block compression hemostasis (control group), 25 cases in each group. The complete hemostasis time, compression displacement, bleeding, hematoma incidence and the convenience of single hand operation were compared between the two groups.Results:The complete hemostasis time of the control group was (36.37±2.12) min, and that of the experimental group was (20.52±3.65) min, the difference was statistically significant ( t value was 83.695, P<0.01). The incidence of displacement, hemorrhage and hematoma in the control group were 5.20% (26/500), 13.60% (68/500) and 3.00% (15/500) respectively, and those in the experimental group were 0, 8.20% (41/500) and 0 respectively, and the differences between the two groups were statistically significant ( χ2 value was 7.506, P<0.01). The one hand operation rate of the control group was 44.00% (220/500), and that of the experimental group was 98.00% (490/500). The difference between the two groups was statistically significant ( χ2 value was 354.055, P<0.01). Conclusions:The hemostatic air cushion with exhaust regulating valve is applied to patients with autogenous arteriovenous fistula after needle extraction, which has good hemostatic effect, simple and convenient operation, and is worthy of clinical promotion.

Objective To assess the methodology of papers on systematic reviews and meta-analysis of interventions published in Journal of Evidence-Based Medicine .Methods Basic data were extracted from 70 papers on systematic reviews and meta-analysis of interventions published in Journal of Evidence-Based Medicinefrom 2001 to 2011 .Methodology used in these papers was assessed according to the AMSTAR Scale.The data were input into the Excelland analyzed using the SPSS7.0 and Meta-Analyst software.Results The methodology used in 34 papers (48.6%) was assessed using the Cochrane bias risk assessment tools.Fund support, number of authors and their affiliated institutions did not sig-nificantly affect the total score of methodology used in the 70 papers .Conclusion The methodology used in papers on systematic reviews and meta-analysis of interventions published in Journal of Evidence-Based Medicine is not quite valid as its early design program and retrieval strategies are imperfect , and it does not provide the excluded literature list and the interest conflict.

Objective:To analyze the clinical features and prognosis factors of aquaporin 4 (AQP4) antibody-positive neuromyelitis optica spectrum disorders related optic neuritis (NMOSD-ON).Methods:An ambidirectional cohort study. From June 1, 2015 to June 1, 2019, 103 patients with AQP4 antibody-positive NMOSD-ON in Department of Neuro-ophthalmology, The First Medical Center of PLA General Hospital were included. All patients of followed-up period were ≥24 months. According to the best corrected visual acuity (BCVA) at the last follow-up, the affected eyes were divided into the low vision group [log of minimum resolution angle (logMAR) BCVA≥1.0] and the non-low vision group (logMAR BCVA<1.0), 66 and 37 cases, respectively. The two groups of patients were compared the genernal clinical characteristics, and the logistic regression model and COX proportional hazard model were used to analyze the relevant factors affecting the patient's visual prognosis and recurrence.Results:Among the 103 cases, 96 cases (93.2%, 96/103) were female; 94 cases (91.3%, 94/103) had unilateral disease; 48 cases (46.6%, 48/103) were the first onset; 85 cases (82.5%, 85/103) were effected by eye pain or orbital pain; 21 cases (20.4%, 21/103) had optic disc edema; 51 cases (49.5%, 51/103) serologically autoimmune antibody test were positive. Orbital magnetic resonance imaging (MRI) was performed in 101 cases. There was no obvious abnormal signal in visual pathways except for 5 cases (5.0%, 5/101); 96 cases (95.0%, 96/101) had abnormal signal in the visual path, and the optic nerve was found in the orbit; 52 cases had abnormal optic nerve in orbital segment (51.5%, 52/101); 37 cases (35.9%, 37/103) recurred within 24 months. The recovery of logMAR BCVA after the first onset and the logMAR BCVA at the first onset, at 6 months of follow-up in two groups were 1.4±1.0, 0.3±0.4, 1.9±0.7 and 0.4±0.5, 2.1±0.6, 0.3±0.4, respectively; and there were statistically significant differences between the two groups of patients at different times ( Z=-4.967,-7.603,-8.027; P<0.001). Logistic regression multivariate analysis showed that recovery of BCVA≥1.0 logMAR after the first onset [odds ratio ( OR)=226.276, P<0.001 ] and the number of attacks ( OR=8.554, P=0.003) were independent risk factors for low vision. Multivariate analysis of the Cox proportional hazards model showed the higher the MRI score [hazard ratio ( HR)=0.588, P=0.007] and plasma exchange ( HR=0.124, P=0.049) in the acute phase were protective factors for recurrence. Conclusions:Vision loss accompanied by eye pain or orbital pain is the main symptom of onset AQP4 antibody-positive NMOSD-ON, a small number of patients have disc edema, 49.5% patients serologically autoimmune antibody test are positive. Abnormal optic nerve signals can be seen in 95.0% of patients in orbital MRI, and 51.5% patients have abnormalities in the orbital optic nerve. The worse the recovery of BCVA after the first onset and the greater the number of attacks are unfavorable factors affecting the prognosis of vision. High MRI scores and plasma exchange in the acute phase are favorable factors to prevent the recurrence of the disease.

Tuberculosis(TB) caused by the Mycobacterium tuberculosis(Mtb) is a worldwide public health threat.Microbiota in body affects human health and is involved in human diseases, and its clinical importance is begi-nning to be understood.In this review, studies on the relationship between the establishment of Mtb infection and microbiota as well as the development and antibiotic treatment of Mtb infection were discussed.Studies have shown that: (1) microbiota influences the establishment of Mtb infection; (2) co-infection of Helicobacter pylori alters susceptibility to Mtb infection and progression of active TB; (3) microbiota influences the progression of TB by regulating the nutritio-nal, metabolic and immune status of the host; (4) susceptibility to reinfection increases in TB patients treated with antibiotics, possibly due to T-cell epitope depletion of common intestinal non-Mtb Mycobacterium, the effects of antibio-tics are long-term in patients; (5) the occurrence of childhood TB is age-related and many factors such as co-infection and vaccine inoculation increase risk.An in-depth study of the relationship between the microbiota and TB will provide a new perspective on the prevention of TB.

Objective To evaluate the efficacy and safety of 27-gauge sutureless vitrectomy with air tamponade for rhegmatogenous retinal detachment (RRD).Methods The clinical data of 35 consecutive eyes with primary RRD from 35 patients who received 27-gauge vitrectomy with intraocular air tamponade in Zhongshan Eye Center from April 2016 to January 2017 were retrospectively analyzed.The mean follow-up duration was 8.6 months.Best corrected visual acuity (BCVA) (LogMAR) and intraocular pressure (IOP) were examined before surgery,1 week and 3 months after surgery.The operative duration,sclerotomy sites,retinal reattachment rate,intraoperative and postoperative complications were recorded.Results The mean duration of vitreous removal was (15.3 ± 3.6) minutes,and the mean duration of operation was (34.5 ± 4.8) minutes.No suturing process was performed at sclerotomy sites in all eyes.The retinal reattachment rate following a single procedure was 100％.The mean BCVA was significantly different among before surgery,1 week and 3 months after surgery (F =64.12,P＜0.01),and the BCVA at 1 week and 3 months after surgery was evidently improved in comparison with before surgery (0.82±0.31 vs.1.01 ±0.40;0.68±0.30 vs.1.01 ±0.40) (both at P＜0.05).The mean IOP was (14.69±3.66),(17.37±2.32) and (16.69±2.45) mmHg (1 mmHg =0.133 kPa) before surgery,1 week and 3 months after surgery,showing a significant difference among them (F=14.82,P＜0.01),and the IOP 1 week and 3 months after surgery was evidently higher than that before surgery (both at P＜0.05).The complications included intraoperative iatrogenic retinal breaks in 2 eyes,postoperative hypotony in 1 eye and hypertension in 5 eyes.These complications were curable.Conclusions 27-Gauge vitrectomy and air tamponade for RRD is an effective and safe approach.

Objective To study the trends in surgical treatment and the outcomes of critical acute pancreatitis (CAP).Methods The clinical data of 76 patients with CAP who were treated in the Department of Biliopancreatic Surgery of the Xiangya Hospital,Central South University from January 2010 to December 2017 were retrospectively reviewed.Data which included demographics,micro-organisms,surgical interventions and mortality were compared between the time periods of 2010 to 2013 and 2014 to 2017.Results Before 2014,19 patients with CAP were treated in the Department of Biliopancreatic Surgery of the Xiangya Hospital,Central South University.The percentage of multidrug resistant organisms (MDRO) in pancreatic drainage was 5.3％ (1/19).In the latter 4 years,57 patients with CAP were treated.The percentage of MDRO was 50.9％ (29/57),which was significandy higher than the initial 4 years (P＜0.001).For surgical treatment,the proportion of minimally invasive surgery in the latter 4 years was significantly higher than that in the initial 4 years.The percentage of percutaneous catheter drainage (PCD) increased from 63.2％ in the initial 4 years to 86.0％ in the latter 4 years.The proportion of minimal access retroperitoneal pancreatic necrosectomy (MARPN) increased from zero in the initial 4 years to 59.6％,while the proportion of open pancreatic necrosectomy (OPN) decreased from 68.4％ in the initial 4 years to 24.6％.The mortality rate of patients with CAP dropped from 52.6％ (10/19) in the initial 4 years to 24.6％ (14/57) in the latter four years.Conclusions In the center which specializes in treating pancreatitis,although the problem of bacterial resistance had become increasingly prominent,the mortality rate of CAP had shown a significant downward trend due to the development of various minimally invasive techniques.

Objective:To investigate the clinical, laboratory and imaging evaluation, treatment and prognosis of patients with idiopathic hypertrophic pachymeningitis (IHP) with ophthalmic manifestations as the first symptom.Methods:A retrospective case analysis. Eight patients displaying symptoms of IHP were recruited from the Neuro-ophthalmology Department in the First Medical Center of Chinese PLA General Hospital from January 2016 to April 2019 were inculed in this study. There were 6 males and 2 females, aged from 11 to 65 years, with an average age of 48.00±19.08 years. The course of disease ranged from 30 days to 7.5 years, with an average course of 17.00±30.08 months. The age, symptoms and signs of all patients were recorded. All patients underwent ophthalmic examination, orbit or brain MRI or CT examinations, blood routine examination, biochemistry, tumor markers, immunity, hepatitis B, syphilis, HIV, thyroid function and other laboratory tests, and lumbar puncture was performed to measure the cerebrospinal fluid (CSF) pressure and indicators. The clinical manifestations, orbital or brain MRI imaging and laboratory examination characteristics were summarized. Treatment and prognosis were also observed.Results:In total of 8 patients, visual loss was presented in 6 patients, visual loss and diplopia were presented in 1 patient, and diplopia was presented in 1patient. Binocular involvement in 7 patients and monocular involvement in 1 patient. Other symptoms including headache and hear loss and so on. Optic disc edema in 1 eye and optic disc pallor in 6 eyes were reviewed by fundus examination. The laboratory examination showed that the angiotensin converting enzyme abnormal in 4 patients, the anti-thyroid peroxidase antibody abnormal in 3 patients and immunoantibodies positive in 3 patients. CSF measurements showed that the protein level elevated in all patients. Orbit and/or brain MRI and CT examination showed that optic nerve involvement in 6 patients, oculomotor nerve involvement in 1 patient, and cavernous sinus region involvement in 2 patients. Glucocorticoid was effective in all patients, and the visual acuity significantly improved in 4 patients, the diplopia was completely resolved in 2 patients, and the disease modifying therapy (DMT) was combined to prevent recurrence in 7 patients. No recurrence was observed in an average follow-up time of 26.63±16.55 months.Conclusions:IHP patients may be first visit an ophthalmologist due to vision loss in bilateral eyes simultaneous or sequentially. IHP patients are often associated with headache and other cranial nerve paralysis symptoms. Definitive diagnosis of IHP depends on imaging examination. Glucocorticoid treatment is effective in early phase, but it is tendency to progress and relapse, suggesting combined with DMT as early as possible.

Objective To evaluate the safety and efficacy of interventional embolization of middle meningeal artery(MMA)for the treatment of chronic subdural hematoma(CSDH).Methods The clinical data of 14 patients with CSDH(17 lesions in total),who were treated with simple embolization of MMA at the Yijishan Hospital of Wannan Medical College of China between July 2021 and July 2022,were retrospective analyzed.After superselective catheterization of MMA using a microcatheter was accomplished,Onyx-18 glue,a liquid embolization agent,was used to embolize the main trunk and the branches of MMA.Imaging follow-up was adopted at 30 days and 90 days after discharge from hospital to evaluate the absorption of hematoma,and the improvement of clinical symptoms was defined as the modified Rankin Scale score(mRS)being decreased≥1 point from the baseline value.Results Successful embolization of MMA was accomplished for all the 17 lesions in the 14 patients,and no procedure-related complications occurred.During the follow-up period,the clinical symptoms and signs were remarkably improved in all patients.The postoperative 90-day hematoma volume was reduced by more than 90%in 11 patients and by more than 40%in one patient,and in 2 patients the postoperative 30-day hematoma volume was reduced by more than 30%.Complete absorption of hematoma was seen in 11 patients,and partial absorption of hematoma was observed in 3 patients.Conclusion For the treatment of newly-developed or recurrent CSDH,interventional embolization of MMA is clinically safe and effective.(J Intervent Radiol,2024,32:12-16)

Objective:To investigate the characteristics of senile neurodegenerative diseases (NDDs) inpatients in south China, especially in Guangdong province, and explore the influencing factors for their medical expenses.Methods:The medical records of 7231 patients with NDDs≥65 years were collected in the electronic health database of our hospital from January 2010 to December 2019, including gender, age, admission ways, chief complaints, length of hospital stays and medical expenses. On the basis of median of the medical expenses (21 345 yuan) of these patients, they were divided into low cost (<21 345 yuan) group and high cost (≥21 345 yuan) group. Univariate Logistic analysis and multivariate Logistic regression analysis were conducted to screen the influencing factors for medical expenses and the independent influencing factors.Results:(1) The main age group of geriatric inpatients with NDDs were 70-79 years (40.96%); the admission source was mainly outpatient (56.70%), and length of hospital stays of a large percent of patients (44.50%) were 8-14 d. (2) From 2010 to 2019, the number of hospitalized geriatric patients with NDDs showed an increasing trend year by year, the overall trend of length of hospital stays was shortened, and the medical expenses showed gradual increase; the causes of hospitalization, percentages of patients caused by infection, abnormal blood pressure and water-electrolyte metabolism disturbances showed decreased trend, percentages of patients caused by heart diseases, cerebrovascular accidents and mental-psychological diseases showed increased trend, and the proportions of patients caused by fracture/trauma/wound injuries were generally stable. The proportion of patients returning home and mortality rate after hospital discharge were declined, and the proportion of patients returning to other medical or community institutions was increased. (3) Living in ICU, length of hospital stays, diabetes, nosocomial infection, chronic kidney disease, urinary tract infection, tumble, body mass index, and anticholinergic drugs were independent risk factors influencing the medical expenses ( P<0.05). Conclusions:An aging trend is noted in patients with NDDs; the number of hospitalized patients and medical expenses increase year by year, and the length of hospital stays gradually decreases. In view of the many factors that influence the medical expenses of this disease, it is suggested to develop the corresponding standardized treatment plan for the main influencing factors in clinical practice.

ObjectiveTo explore the prevalence difference between northwest dryness syndrome and blood stasis syndrome of coronary heart disease （CAD） and their correlations with major adverse cardiovascular events （MACE）. MethodsThe medical records including general information and risk factors for vascular diseases （gender， age， smoking history， diabetes history， hypertension history， chronic kidney disease history and body mass index）， laboratory indicators （fasting blood glucose， triglyceride， high density lipoprotein cholesterol， etc.） of 499 CAD patients in the Department of Cardiology of the Affiliated Hospital of Traditional Chinese Medicine of Xinjiang Medical University from November 1st， 2015 to September 30th，2020 were collected， and whether they suffered from northwest dryness syndrome or blood stasis syndrome was judged. The incidence of MACE was followed up for one year. The differences of cardiovascular risk factors between the northwest dryness syndrome and blood stasis syndrome of CAD were compared， and the correlation with MACE was analyzed. ResultsAmong the 499 CAD patients， there were 128 cases （25.65%） of simple blood stasis syndrome， 33 cases （6.61%） of simple northwest dryness syndrome， 209 cases （41.88%） of northwest dryness syndrome plus blood stasis syndrome， and 129 （25.85%） cases of not blood statis syndrom either northwest dryness syndrome. Univariate regression analysis showed that smoking history， diabetes history， fasting blood glucose abnormality， triglyceride abnormality， and high density lipoprotein cholesterol abnormality were positively correlated with northwest dryness syndrome in CAD patients （OR＞1， P＜0.05）， while smoking history， abnormal triglyceride and abnormal high density lipoprotein cholesterol were positively correlated with blood stasis syndrome in CAD patients （OR＞1， P＜0.05）. Multivariate regression analysis showed that the history of diabetes， abnormal triglyceride and abnormal high density lipoprotein cholesterol were positively correlated with northwest dryness syndrome of CAD （P＜0.05）. Smoking history， abnormal triglycerides and abnormal high density lipoprotein cholesterol were positively correlated with blood stasis syndrome （P＜0.05）. Association rule analysis showed that the confidence of CAD patients with northwest dryness syndrome complicated with blood stasis syndrome was 86.36%， and that of patients with blood stasis syndrome complicated with northwest dryness syndrome was 62.02%. Among the 499 patients， 96 had MACE in one year， accounting for 19.24% of the total. Logistics regression analysis showed that the correlation with incidence of MACE in CAD patients within one year from strong to weak was northwest dryness syndrome plus blood stasis syndrome ［OR = 5.113， 95%CI （3.118， 8.387）， P＜0.001）］， blood stasis syndrome［OR = 4.630， 95%CI （2.394， 8.955）， P＜0.001］， northwest dryness syndrome ［OR = 4.395， 95%CI （2.642， 7.309）， P＜0.001］. ConclusionBlood stasis syndrome is the main syndrome type of CAD in Xinjiang Uygur Autonomous Region. CAD patients with northwest dryness syndrome are more likely to have blood stasis syndrome， and most suffer from both northwest dryness syndrome and blood stasis syndrome simultaneously. There is the strongest correlation between northwest dryness syndrome plus blood stasis syndrome and 1-year occurrence of MACE in CAD.
