Objective We aimed to evaluate the clinical efficacy of promoting blood circulation and eliminating phlegm method in preventing and treating patients with hydrocephalus after acute intracerebral hemorrhage.Methods This study included 139 patients with acute intracerebral hemorrhage who visited Affiliated Hospital of Chengdu University of Traditional Chinese Medicine,Guangyuan Hospital of Traditional Chinese Medicine,Affiliated Hospital of North Sichuan Medical College,Meishan Hospital of Traditional Chinese Medicine,and Xuyong Hospital of Traditional Chinese Medicine from September 2019 to June 2023.Patients who met the exposure factors of"using the method of promoting blood circulation and eliminating phlegm"were classified into the integrated Chinese and Western medicine cohort,while those who did not meet the exposure factors were classified into the Western medicine cohort.Clinical efficacy,incidence of hydrocephalus after intracerebral hemorrhage,sum of maximum distance between the anterior horn of the lateral ventricle and the head of the caudate nucleus(Huckman value),size of the hematoma,incidence of endpoint events,National Institutes of Health Stroke Scale(NIHSS)score,Modified Rankin Scale(mRS)score,and Barthel index score between two cohorts were compared.Results Total clinical effective rates for patients with hydrocephalus in the two cohorts were 60.0%and 75.0%,respectively.The total effective rate of the integrated Chinese and Western medicine cohort was higher than that of the Western medicine cohort(P<0.05).After 28 days of treatment,the incidence of hydrocephalus in patients in the integrated Chinese and Western medicine cohort was lower than that of the Western medicine cohort,and the Huckman value decreased compared with the Western medicine cohort(P<0.05).Compared with 24 hours after onset,both cohorts showed a reduction in hematoma size after 28 days of treatment;compared with the Western medicine cohort,patients in the integrated Chinese and Western medicine cohort had reduced hematoma size(P<0.05).After 6 months of onset,the number of deaths in the integrated Chinese and Western medicine cohort decreased compared with the Western medicine cohort(P<0.05).Compared with 28 days of treatment,the NIHSS and mRS scores of the patients in both cohorts decreased after 6 months,while the Barthel index score increased;compared with the Western medicine cohort,patients in the integrated Chinese and Western medicine cohort showed a decrease in the NIHSS and mRS scores after both 28 days of treatment and 6 months,while the Barthel index score increased(P<0.05).Conclusion Promoting blood circulation and eliminating phlegm can effectively prevent and treat hydrocephalus after intracerebral hemorrhage and does not increase the risk of bleeding within 24 hours.

Cerebral ischemic stroke is an acute cerebrovascular disease caused by cerebral vascular occlusion, and it is associated with high incidence, disability, and mortality rates. Studies have found that excessive or insufficient autophagy can lead to cellular damage. Autophagy consists of autophagosome formation and maturation, autophagosome-lysosome fusion, degradation and clearance of autophagic substrates within autolysosomes, and these processes collectively constitute autophagic flux. Research has revealed that cerebral ischemia can induce impaired fusion between autophagosomes and lysosomes, resulting in autophagic flux impairment. Intracellular membrane fusion is mediated by three core components: N-ethylmaleimide sensitive factor (NSF) ATPase, soluble NSF attachment protein (SNAP), and soluble NSF attachment protein receptors (SNAREs). SNAREs, after mediating fusion between autophagosomes and lysosomes, remain in an inactive complex state on the autolysosomal membrane, requiring NSF reactivation into monomers to perform subsequent rounds of membrane fusion-mediated functions. NSF is the sole ATPase capable of reactivating SNAREs. Recent studies have shown that cerebral ischemia significantly inhibits NSF ATPase activity, reducing its reactivation of SNAREs. This may be a pathological mechanism for impaired fusion between autophagosomes and lysosomes, leading to neuronal autophagic flux impairment. This article discusses the pathological mechanisms of NSF ATPase inactivation, including SNAREs dysregulation, impaired fusion between autophagosomes and lysosomes, and insufficient transport of proteolytic enzymes to lysosomes, and explores approaches to improve neuronal autophagic flux through NSF ATPase reactivation. It provides references for stroke treatment improvement and points out directions for further research.

Objective:To investigate the current situation of the use of transjugular intrahepatic portosystemic shunt (TIPS) for portal hypertension, which should aid the development of TIPS in China.Methods:The China Portal Hypertension Alliance (CHESS) initiated this study that comprehensively investigated the basic situation of TIPS for portal hypertension in China through network research. The survey included the following: the number of surgical cases, main indications, the development of Early-TIPS, TIPS for portal vein cavernous transformation, collateral circulation embolization, intraoperative portal pressure gradient measurement, commonly used stent types, conventional anticoagulation and time, postoperative follow-up, obstacles, and the application of domestic instruments.Results:According to the survey, a total of 13 527 TIPS operations were carried out in 545 hospitals participating in the survey in 2021, and 94.1% of the hospital had the habit of routine follow-up after TIPS. Most hospitals believed that the main indications of TIPS were the control of acute bleeding (42.6%) and the prevention of rebleeding (40.7%). 48.1% of the teams carried out early or priority TIPS, 53.0% of the teams carried out TIPS for the cavernous transformation of the portal vein, and 81.0% chose routine embolization of collateral circulation during operation. Most of them used coils and biological glue as embolic materials, and 78.5% of the team routinely performed intraoperative portal pressure gradient measurements. In selecting TIPS stents, 57.1% of the hospitals woulel choose Viator-specific stents, 57.2% woulel choose conventional anticoagulation after TIPS, and the duration of anticoagulation was between 3-6 months (55.4%). The limitation of TIPS surgery was mainly due to cost (72.3%) and insufficient understanding of doctors in related departments (77.4%). Most teams accepted the domestic instruments used in TIPS (92.7%).Conclusions:This survey shows that TIPS treatment is an essential part of treating portal hypertension in China. The total number of TIPS cases is far from that of patients with portal hypertension. In the future, it is still necessary to popularize TIPS technology and further standardize surgical indications, routine operations, and instrument application.

Objective To investigate the short-term efficacy and safety of chemotherapy induced by nimotuzumab(NTZ)combined with TP regimen and sequential concurrent chemoradiotherapy in patients with epidermal growth factor receptor positive(EGFR-positive)locally advanced nasopharyngeal carcinoma.Methods A total of 48 patients with stage Ⅲ to Ⅳ A nasopharyngeal carcinoma in Guizhou Provincial People's Hospital from January 2020 to December 2022 were prospectively enrolled,and were randomized into two groups:NTP(NTZ+docetaxel/albumin-paclitaxel+cisplatin)group and TP(Docetaxel/albumin-paclitaxel+cisplatin)group(24 cases per group)by random number table method.After 2 or 3 cycles of induction chemotherapy in NTP group,NTZ was sequentially used in combination with cisplatin for concurrent chemoradiotherapy.Immunohistochemistry was used to detect the EGFR expression level,exploring EGFR expression intensity and the therapeutic effect of NTZ in NTP group patients.Meanwhile,short-term efficacy,withdrawal rate and toxic side effects were compared between the two groups after induction chemotherapy.Results In NTP group,the positive expression rate of EGFR was 100％,and EGFR expression intensity significantly correlated with the efficacy of NTZ-combined induction therapy(P<0.05).After induction chemotherapy,the objective response rate(ORR)of cervical lymph nodes in NTP group was significantly higher than that in TP group(75％vs.45.8％,P=0.039).The primary lesion ORR and overall(primary lesion and cervical lymph node)ORR showed no significant difference between the two groups(P>0.05).Comparison of adverse reactions between the two groups during induction therapy:leukopenia and gastrointestinal reaction in NTP group were lower than those in TP group(P<0.05),but rash was higher than those in TP group(P<0.05).There was no significant difference in liver function,hemoglobin and thrombocytopenia between two groups(P>0.05).Conclusions EGFR expression intensity varies in nasopharyngeal carcinoma tissues,with higher levels indicating greater clinical benefit of combined induction therapy with NTZ.NTZ combined with TP induction regimen demonstrates good short-term efficacy and safety for cervical lymph nodes in patients with locally advanced nasopharyngeal carcinoma.

Objective:To explore the current status of surgery for portal hypertension to grasp current status and future development of surgery in China.Methods:This study is jointly sponsored by China Hepatobiliary & Pancreatic Specialist Alliance & Portal Hypertension Alliance in China (CHESS).Comprehensive surveying is conducted for basic domestic situations of surgery for portal hypertension, including case load, surgical approaches, management of postoperative complications, primary effects, existing confusion and obstacles, liver transplantation(LT), laparoscopic procedures and transjugular intrahepatic portosystemic shunt(TIPS), etc.Results:A total of 8 512 cases of portal hypertension surgery are performed at 378 hospitals nationwide in 2021.Splenectomy plus devascularization predominated(53.0%)and laparoscopy accounted for 76.1%.Primary goal is preventing rebleeding(67.0%) and 72.8% of hospitals used preventive anticoagulants after conventional surgery.And 80.7% of teams believe that the formation of postoperative portal vein thrombosis is a surgical dilemma and 65.3% of hospitals practiced both laparoscopy and TIPS.The major reasons for patients with portal hypertension not receiving LT are due to a lack of qualifications for LT(69.3%)and economic factors(69.0%).Conclusions:Surgery is an integral part of management of portal hypertension in China.However, it is imperative to further standardize the grasp of surgical indications, the handling of surgical operation and the management of postoperative complications.Moreover, prospective, multi-center randomized controlled clinical studies should be performed.

Objective: Compare and analyze the results of the domestic Lanyi AH600 glycated hemoglobin analyzer and other different detection systems to understand the comparability of the detection results of different detectors, and establish the best cut point of Lanyi AH600 determination of haemoglobin A1c (HbA1c) in the diagnosis of diabetes. Methods: Multi center cohort study was adopted. The clinical laboratory departments of 18 medical institutions independently collected test samples from their respective hospitals from March to April 2022, and independently completed comparative analysis of the evaluated instrument (Lanyi AH600) and the reference instrument HbA1c. The reference instruments include four different brands of glycosylated hemoglobin meters, including Arkray, Bio-Rad, DOSOH, and Huizhong. Scatter plot was used to calculate the correlation between the results of different detection systems, and the regression equation was calculated. The consistency analysis between the results of different detection systems was evaluated by Bland Altman method. Consistency judgment principles: (1) When the 95% limits of agreement (95% LoA) of the measurement difference was within 0.4% HbA1c and the measurement score was≥80 points, the comparison consistency was good; (2) When the measurement difference of 95% LoA exceeded 0.4% HbA1c, and the measurement score was≥80 points, the comparison consistency was relatively good; (3) The measurement score was less than 80 points, the comparison consistency was poor. The difference between the results of different detection systems was tested by paired sample T test or Wilcoxon paired sign rank sum test; The best cut-off point of diabetes was analyzed by receiver operating characteristic curve (ROC). Results: The correlation coefficient R² of results between Lanyi AH600 and the reference instrument in 16 hospitals is≥0.99; The Bland Altman consistency analysis showed that the difference of 95% LoA in Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180) was -0.486%-0.325%, and the measurement score was 94.6 points (473/500); The difference of 95% LoA in the Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant II) was -0.727%-0.612%, and the measurement score was 89.8 points; The difference of 95% LoA in the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT) was -0.231%-0.461%, and the measurement score was 96.6 points; The difference of 95% LoA in the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT) was -0.469%-0.479%, and the measurement score was 91.9 points. The other 14 hospitals, Lanyi AH600, were compared with 4 reference instrument brands, the difference of 95% LoA was less than 0.4% HbA1c, and the scores were all greater than 95 points. The results of paired sample T test or Wilcoxon paired sign rank sum test showed that there was no statistically significant difference between Lanyi AH600 and the reference instrument Arkray HA8180 (Z=1.665,P=0.096), with no statistical difference. The mean difference between the measured values of the two instruments was 0.004%. The comparison data of Lanyi AH600 and the reference instrument of all other institutions had significant differences (all P<0.001), however, it was necessary to consider whether it was within the clinical acceptable range in combination with the results of the Bland-Altman consistency analysis. The ROC curve of HbA1c detected by Lanyi AH600 in 985 patients with diabetes and 3 423 patients with non-diabetes was analyzed, the area under curve (AUC) was 0.877, the standard error was 0.007, and the 95% confidence interval 95%CI was (0.864, 0.891), which was statistically significant (P<0.001). The maximum value of Youden index was 0.634, and the corresponding HbA1c cut point was 6.235%. The sensitivity and specificity of diabetes diagnosis were 76.2% and 87.2%, respectively. Conclusion: Among the hospitals and instruments currently included in this study, among these four hospitals included Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180), Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant Ⅱ), the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT), and the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT), the comparison between Lanyi AH600 and the reference instruments showed relatively good consistency, while the other 14 hospitals involved four different brands of reference instruments: Arkray, Bio-Rad, DOSOH, and Huizhong, Lanyi AH600 had good consistency with its comparison. The best cut point of the domestic Lanyi AH600 for detecting HbA1c in the diagnosis of diabetes is 6.235%.

OBJECTIVES: To study the factors influencing the short-term (28 days) efficacy of initial adrenocorticotropic hormone (ACTH) therapy for infantile epileptic spasms syndrome (IESS), as well as the factors influencing recurrence and prognosis. METHODS: The clinical data were collected from the children with IESS who received ACTH therapy for the first time in the Department of Pediatric Neurology, Xiangya Hospital of Central South University, from April 2008 to January 2018 and were followed up for ≥2 years. The multivariate logistic regression analysis was used to evaluate the factors influencing the short-term efficacy of ACTH therapy, recurrence, and long-term prognosis. RESULTS: ACTH therapy achieved a control rate of seizures of 55.5% (111/200) on day 28 of treatment. Of the 111 children, 75 (67.6%) had no recurrence of seizures within 12 months of follow-up. The possibility of seizure control on day 28 of ACTH therapy in the children without focal seizures was 2.463 times that in those with focal seizures (P<0.05). The possibility of seizure control on day 28 of ACTH therapy in the children without hypsarrhythmia on electroencephalography on day 14 of ACTH therapy was 2.415 times that in those with hypsarrhythmia (P<0.05). The possibility of recurrence within 12 months after treatment was increased by 11.8% for every 1-month increase in the course of the disease (P<0.05). The possibility of moderate or severe developmental retardation or death in the children without seizure control after 28 days of ACTH therapy was 8.314 times that in those with seizure control (P<0.05). The possibility of moderate or severe developmental retardation or death in the children with structural etiology was 14.448 times that in those with unknown etiology (P<0.05). CONCLUSIONS Presence or absence of focal seizures and whether hypsarrhythmia disappears after 14 days of treatment can be used as predictors for the short-term efficacy of ACTH therapy, while the course of disease before treatment can be used as the predictor for recurrence after seizure control by ACTH therapy. The prognosis of IESS children is associated with etiology, and early control of seizures after ACTH therapy can improve long-term prognosis.

Objective:To investigate the diagnostic method and value of echocardiography in screening right patent ductus arteriosus(PDA) of infants.Methods:This was a prospective study.Thirty-one infants with right PDA diagnosed by ultrasound and confirmed by prenatal ultrasonography, electronic computed tomography angiography, angiocardiography and/or surgery in Hebei Children′s Hospital from April 2014 to May 2022 were collected as research subjects, and the association of right ductus arteriosus with aortic arch anomalies and complex cardiac malformations were summarized. The diagnostic method and value of ultrasonic screening were summed up.Results:Of the 31 cases, 30 cases were correctly diagnosed by ultrasound and 1 case was misdiagnosed, who was a left aortic arch descending to the right, a crossover variation of the right and left pulmonary arteries, and a rightward displacement of the ductus arteriosus. Among these cases diagnosed correctly, 27 cases (including 24 cases with right aortic arch and 3 cases with left aortic arch) presented that ductus arteriosus was open and its ostium of pulmonary artery end was located in the proximal right pulmonary artery in views of parasternal short-axis view of great vessels at cardiac base with the combination of two dimensions and color Doppler flow imaging. Other 3 cases of right aortic arch were all single ventricle with transposition of the great artery. Due to the parallel relationship of the two great arteries, the standard parasternal short-axis view of great vessels could not be obtained, and the right ductus arteriosus was found in the high parasternal views.In all of the 27 cases with right aortic arch and right ductus arteriosus, high parasternal views showed that one end of the ductus arteriosus was connected to the right aortic arch isthmus and the other end was connected to the right pulmonary artery. In all of the 3 cases with left aortic arch and right ductus arteriosus, the high parasternal views showed that one end of the ductus arteriosus was connected to the right subclavian artery and the other end was connected to the right pulmonary artery. Among the 27 cases with right aortic arch, 16 cases were accompanied with mirror image branches, 9 cases of which had complex cardiac malformations; 10 cases were associated with aberrant left subclavian artery, 1 case of which had complex cardiac malformations; 1 case was with isolated left subclavian artery, and without complex cardiac malformations. All 3 cases of left aortic arch were accompanied with isolated right subclavian artery and none of them were associated with complex cardiac malformations. Clinical outcomes of 30 cases with right PDA: 14 cases underwent ductus arteriosus ligation due to thick ductus or other heart malformations. In other 16 cases, 4 cases were closed spontaneously, 9 cases had persistent small ductus arteriosus, and 3 cases were lost to follow-up.Conclusions:Right ductus arteriosus is mostly related to the right aortic arch, and those with mirror image branches are prone to complex cardiac malformations; cases of left aortic arch with right ductus arteriosus are tend to accompany isolated right subclavian artery. Ultrasound has an important application in the screening and diagnosis of right PDA.

Objective To investigate the Gram-positive coccus resistance in nationwide's tertiary hospitals and understand the trend of antimicrobial resistance.Methods All the clinical isolates were collected from 19 hospitals and the minimal inhibitory concentrations(MICs)were tested using agar/broth dilution method recommended.Results A total of 1 974 pathogenic Gram-positive coccus from 19 tertiary hospitals in 19 cities nationwide over the period from July 2021 to June 2022 were studied.Based on the MIC results,the prevalence of methicillin resistant Stapylococcus aureus(MRSA)and methicillin resistant Stapylococcus epidermidis(MRSE)were 36.4％and 79.9％respectively.No vancomycin insensitivity Staphylococcus was detected.Staphylococcus aureus were 100％susceptibility to linezolid and teicoplanin.Antibiotic resistance rate of Enterococcus faecalis and Enterococcus faecium to ampicillin were 3.1％and 92.9％.The detectation rate of vancomycin resistant Enterococcus(VRE)was 1.6％.Nonsusceptibility rate of Enterococcus faecalis to linezolid was 32.2％,two consecutive monitoring rises and nonsusceptibility rate of Enterococcus faecium(12.5％)was also significantly increased.The prevalence of penicillin non-susceptible Streptococcus pneumoniae(PNSSP)was 0.8％based on non-meningitis and parenteral administration criterion,decrease of nearly 30 percentage points from the previous surveillance.While for cases of oral penicillin,the rate was 71.8％,showing similar to last time.The results indicated that the number of strains with higher MIC value of penicillin(MIC ≥4 mg·L-1)decreased significantly.There were no significant differences of resistance rates of Stapylococcus aureus,Stapylococcus epidermidis,Enterococcus faecalis,Enterococcus faecium and Streptococcus pneumoniae among various groups such as different department,age,or specimen source.Conclusion VRE detection ratio stablized at a relatively low level.The number of Streptococcus pneumoniae with higher MIC value of penicillin decreased significantly compared with the previous monitoring.The increase of linezolidin-insensitive Enterococcus was noteworthy.
