Objective: To compare the prognosis of mildly or severely symptomatic patients with obstructive hypertrophic cardiomyopathy (OHCM) who underwent alcohol septal ablation (ASA). Methods: This retrospective study cohort consisted of patients with OHCM who received ASA treatment in Beijing Anzhen Hospital, Capital Medical University from March 2001 to August 2021. These patients were divided into mildly and severely symptomatic groups according to the severity of clinical symptoms. Long-term follow-up was conducted, and the following data were collected: duration of follow-up, postoperatire treatment, New York Heart Association (NYHA) classification, arrhythmia events and pacemaker implantation, echocardiographic parameters, and cause of death. Overall survival and survival free from OHCM-related death were observed, and the improvement of clinical symptoms and resting left ventricular outflow tract gradient (LVOTG) and the incidence of new-onset atrial fibrillation were evaluated. The Kaplan-Meier method and log-rank test were used to determine and compare the cumulative survival rates of the different groups. Cox regression analysis models were used to determine predictors of clinical events. Results: A total of 189 OHCM patients were included in this study, including 68 in the mildly symptomatic group and 121 in the severely symptomatic group. The median follow-up of the study was 6.0 (2.7, 10.6) years. There was no statistical difference in overall survival between the mildly symptomatic group (5-year and 10-year overall survival were 97.0% and 94.4%, respectively) and the severely symptomatic group (5-year and 10-year overall survival were 94.2% and 83.9%, respectively, P=0.405); there was also no statistical difference in survival free from OHCM-related death between the mildly symptomatic group (5-year and 10-year survival free from HCM-related death were 97.0% and 94.4%, respectively) and the severely symptomatic group (5-year and 10-year survival free from HCM-related death were 95.2% and 92.6%, respectively, P=0.846). In the mildly symptomatic group, NYHA classification was improved after ASA (P<0.001), among which 37 patients (54.4%) were in NYHA class Ⅰ, and the resting left ventricular outflow tract gradient (LVOTG) decreased from 67.6 (42.7, 90.1) mmHg (1 mmHg=0.133 kPa) to 24.4 (11.7, 35.6) mmHg (P<0.001). In severely symptomatic group, NYHA classification was also improved post ASA (P<0.001), among which 96 patients (79.3%) improved by at least one NYHA classification, and the resting LVOTG decreased from 69.6 (38.4, 96.1) mmHg to 19.0 (10.6, 39.8) mmHg (P<0.001). The incidence of new-onset atrial fibrillation was similar between the mildly and severely symptomatic groups (10.2% vs. 13.3%, P=0.565). Cox multivariate regression analysis showed that age was an independent predictor of all-cause mortality in OHCM patients post ASA (HR=1.068, 95%CI 1.002-1.139, P=0.042). Conclusions: Among patients with OHCM treated with ASA, overall survival and survival free from HCM-related death were similar between mildly symptomatic group and severely symptomatic group. ASA therapy can effectively relieve resting LVOTG and improve clinical symptoms in mildly or severely symptomatic patients with OHCM. Age was an independent predictor of all-cause mortality in OHCM patients post ASA.

Objective: To evaluate the clinical value of dynamic volumetric CT perfusion combined with energy spectrum imaging in bronchial arterial chemoembolization (BACE) in patients with lung cancer. Methods: The data of 31 patients with lung cancer confirmed by pathology and treated with BACE in Lishui Central Hospital from January 2018 to February 2022 were retrospectively collected, including 23 men and 8 women, aged 31-84 (67) years. All patients received perfusion scans of lesion sites within 1 week before surgery and 1 month after surgery. We collected and compared the changes in preoperative and postoperative perfusion parameters such as blood flow (BF), blood volume (BV), mean through time (MTT), permeability surface (PS) and energy spectrum parameters including arterial phase CT value (CTA), venous phase CT value (CTV), arterial phase iodine concentration (ICA), venous phase of iodine concentration (ICV), arterial standardization iodine concentration (NICA), and intravenous standardized iodine concentration (NICV) to confirm the significance of these parameters in evaluating the short-term efficacy of BACE in the treatment of advanced lung cancer. Data normality was tested using the Kolmogorov-Smirnov test and normally distributed measurement data are expressed here as mean ± standard deviation; the independent-samples t-test was used for comparisons between two groups. The measurement data that were not normally distributed are expressed as median (interquartile interval) [M (Q₁, Q₃)], and the comparison between the two groups used the Kruskal-Wallis test. Count data are expressed as cases (%), and comparisons between groups used the χ² test. Results: The objective response rate (ORR) and disease control rate (DCR) at 1 month after BACE were 54.8% (17/31) and 96.8% (30/31), respectively. CT perfusion parameters and energy spectrum parameters of patients before and after BACE treatment were compared. The results showed that BF, BV, MTT, ICA, ICV and NICV were significantly decreased after BACE treatment compared with before treatment, and the differences were statistically significant[58.06 (40.47,87.22) vs.23.57(10.92, 36.24) ml·min^-1·100g^-1,3.33(2.86,6.09) vs.2.12(1.96,3.61)ml/100g,2.70(2.19,3.88) vs.1.53 (1.12,2.25)s, 3.51 (3.11,4.14)vs.1.74 (1.26,2.50)mg/ml,2.00 (1.30,2.45) vs.1.32(0.92,1.76)mg/ml,0.51(0.42,0.57) vs.0.33(0.23,0.39)](all P<0.05). At the same time, compared with the non-remission group, the study results showed that the difference of parameters in remission group before and after BACE was more obvious, including ΔBF, ΔBV, ΔMTT, ΔPS, ΔCTA, ΔCTV, ΔICA, ΔICV, ΔNICA, ΔNICV were significantly increased, and the difference was statistically significant [36.82(32.38, 45.34) vs.9.50(-1.43, 12.34) ml·min^-1·100g^-1,4.46(2.52, 5.79) vs.0.22(-0.76, 4.09) ml/100g,4.22(2.25, 6.77) vs.0.43(-2.53, 1.88) s,10.07 (2.89, 13.13) vs.-2.01(-6.77, 4.28) ml·min^-1·100g^-1,14.22(11.88, 20.57) vs.4.18(-5.25, 6.37) HU, 34.6(14.88, 43.15) vs.11.60(0.26, 25.05) HU,0.95(0.54, 1.47) vs.0.11(0.20, 0.59) mg/ml,1.57(1.10, 2.38) vs. 0.26(-0.21, 0.63) mg/ml,0.05(0.03, 0.08) vs.-0.02(-0.04, 0.01),0.18(0.13, 0.21)vs. 0.11(-0.06, 0.16)](all P<0.05). Conclusions: CT perfusion combined with spectral imaging could effectively evaluate the changes in tumor vascular perfusion in patients with advanced lung cancer before and after BACE treatment, which has important value in judging the short-term efficacy after treatment.

Objective To investigate the clinical efficacy of triamcinolone acetonide combined with punch excision in the treatment of keloids.Methods Patients with keloids diagnosed and treated in The First Affiliated Hospital,Zhejiang University School of Medicine from January 2021 to January 2022 were retrospectively collected.Patients with keloids were divided into conservative(triamcinolone acetonide and fluorouracil)and non-conservative(punch excision combined with treamcinolone acetonide and fluorouracil)according to their treatment regimens.The scores of the Patient and Observer Scar Assessment Scale(POSAS),the Vancouver Scar Scale(VSS)and the Visual Analogue Rating Scale(VAS)were compared before and after treatment,the total effective rate was calculated to evaluate,the clinical efficacy,and the occurrence of adverse events was observed to evaluate the safety.Results A total of 99 patients with keloids were included in the study,including 53 in the conservative treatment group and 46 in the non-conservative treatment group.Before treatment,there was no significant difference in POSAS score,VSS score and VAS score between the two groups(P>0.05).Compared with the conservative treatment group,the POSAS score,VSS score and VAS score of the non-conservative treatment group decreased significantly after treatment(P<0.05).The total effective rate of treatment in the non-conservative treatment group was significantly higher than that in the conservative treatment group(P<0.05).In terms of adverse reactions,the risk of bleeding increased,the incidence of skin pigmentation decreased,and the telangiecasia and skin atrophy didn't occur in the non-conservative treatment group.Conclusion Triamcinolone acetonide combined with punch excision has a significant effect on keloids,which can reduce the incidence of skin atrophy but increase the risk of bleeding.

OBJECTIVE: To investigate the clinical features, distribution of pathogenic bacteria, and drug resistance of bloodstream infection in children with acute leukemia. METHODS: Clinical data of 93 blood culture-positive children with acute leukemia from January 2015 to December 2019 in Department of Pediatrics, The Second Hospital of Anhui Medical University were analyzed retrospectively. RESULTS: In these 93 cases, 78 cases were in the period of neutrophil deficiency. There were 54 Gram-negative bacteria (G^-) (58.1%) found through blood culture, and the top 4 strains were Escherichia coli (15.1%), Klebsiella pneumoniae (13.9%), Pseudomonas aeruginosa (6.5%), and Enterobacter cloacae (6.5%). There were 39 Gram-positive bacteria (G⁺) (41.9%) detected, and the top 4 strains were Staphylococcus epidermidis (10.8%), Streptococcus pneumoniae (6.5%), Staphylococcus hemolyticus (5.4%), and Staphylococcus human (5.4%). Among 74 strains of pathogenic bacteria from acute lymphoblastic leukemia (ALL) children, there were 29 strains of G⁺ bacteria (39.2%) and 45 strains of G^- bacteria (60.8%). While in 19 strains from acute myeloblastic leukemia (AML) patients, G^- bacteria accounted for 47.4% and G⁺ bacteria accounted for 52.6%. In 15 ALL children without neutropenia, G⁺ bacteria made up the majority of the strains (66.7%). In the 93 strains of pathogenic bacteria, 13 (13.9%) strains were multidrug-resistant. Among them, extended-spectrum β-lactamases accounted for 42.9%, carbapenemase-resistant enzyme Klebsiella pneumoniae 15.4%, and carbapenemase-resistant enzyme Enterobacter cloacae strains 33.3%, which were detected from G^- bacteria. While, 13.3% of methicillin-resistant coagulase-negative Staphylococci accounted for 13.3% detected from G⁺ bacteria, but linezolid, vancomycin, teicoplanin Staphylococcus and Enterococcus resistant were not found. The average procalcitonin (PCT) value of G^- bacteria infection was (11.02±20.282) ng/ml, while in G⁺ infection it was (1.81±4.911) ng/ml, the difference was statistically significant (P<0.05). The mean value of C-reactive protein (CRP) in G^- infection was (76.33±69.946) mg/L, and that in G⁺ infection was (38.34±57.951) mg/L. The prognosis of active treatment was good, and only one case died of septic shock complicated with disseminated intravascular coagulation (DIC) and gastrointestinal bleeding caused by carbapenemase-resistant enzyme enterobacteriaceae. CONCLUSION G^- is the major bacteria in acute leukemia children with bloodstream infection, but the distribution of ALL and AML strains is different. G^- bacteria dominates in ALL, while G⁺ bacteria and G^- bacteria are equally distributed in AML. Non-agranulocytosis accompanied by bloodstream infections is dominant by G⁺ bacteria. The mean value of PCT and CRP are significantly higher in G^- bacteria infection than in G⁺ bacteria.

OBJECTIVE: To study the risk factors and infection characteristics of nosocomial infection in children with acute lymphoblastic leukemia (ALL) and analyze the relationship between different nutritional status and nosocomial infection, early treatment response. METHOD: The clinical data of 133 children with ALL treated with CCCG-ALL-2015 from June 2016 to June 2019 (chemotherapy stage, risk level, MRD), infection during hospitalization (course of infection, laboratory indicators, sites of infection, outcome) and nutritional status (sex, age, height/ length, weight) were enrolled. The Chi 2 test and Logistic regression analysis were used for statistical analysis. RESULTS: The rate of nosocomial infection was 19.9% in 133 children with ALL, in which 3 were infection-related death. Sex, immunophenotype and risk showed no significantly affect on the occurrence of nosocomial infection (P＞0.05), but neutrophil count, hemoglobin level, platelet count, chemotherapy stage, length of stay in hospital and nutritional status showed affect on the occurrence of nosocomial infection (P＜0.05). Logistic multivariate regression analysis showed that chemotherapy stage, length of hospital stay, neutrophils and nutritional status were the independent risk factors, in which the respiratory tract infection was the most common. Gram-positive bacteria, Gram-negative bacteria and fungi accounted for 44.1%, 52.9% and 2.9% respectively. The negative rate of MRD in day 19 and day 46 between different nutritional status groups showed statistically significant (P＜0.05). CONCLUSION Neutrophil count, chemotherapy stage, length of stay in hospital and nutritional status are independent risk factors for nosocomial infection. Among of them, nutritional status negatively correlated with nosocomial infection, and the poorer nutritional status, the higher risk of nosocomial infection. Malnutrition, overweight and obesity can affect the early treatment response of ALL children. The level of nutrition at first diagnosis can be used as a bad factor to evaluate the early treatment response of ALL children.

OBJECTIVE: To review systematically the safety and effectiveness of acupuncture-related therapies on ovulation rate and pregnancy rate in patients with polycystic ovary syndrome (PCOS). METHODS: From PubMed, EMbase, the Cochrane Library, China Biology Medicine disc (CBM), China National Knowledge Infrastructure (CNKI), Wanfang database and VIP database, the randomized controlled trials (RCTs) on PCOS were retrieved in the period from the date of database establishment to January 8, 2018. Two researchers screened the articles, extracted the data and assessed the bias risk of the eligible trials independently. Using Stata 13.0 and WinBUGS 1.4.3 software, the data were analyzed. RESULTS: A total of 39 RCTs were collected, including 4605 cases of PCOS and 14 kinds of acupuncture-related therapies and the comprehensive therapies. The short-term therapeutic effects were observed. The results of mesh meta-analysis showed: regarding the ovulation rate, the effects of the acupuncture-medication therapy were better than western medication. The top 6 therapeutic measures were the treatment with acupoint thread-embedding therapy and medication (93.3%), the treatment with moxibustion and Chinese herbal medicine (91.4%), moxibustion (74.5%), the treatment with acupuncture and medication (65.7%), the treatment with acupuncture-moxibustion and auricular point therapy (61.9%) and the treatment with acupuncture and auricular point therapy (49.6%). Regarding the pregnancy rate, the effects of the acupuncture-medication therapy were better than western medication. The top 6 therapeutic measures were the treatment with acupuncture and auricular point therapy (91.5%), the treatment with moxibustion and Chinese herbal medication (86.9%), the treatment with acupuncture-moxibustion and auricular point therapy (81.1%), the treatment with acupoint thread-embedding therapy and medication (69.4%), the treatment with acupuncture and medication (66.1%) and the treatment with placebo and western medication (58.7%). CONCLUSION Among acupuncture-related therapies, the combined treatment is more advantageous than single therapy and its safety is superior to western medication. The combined therapies are various in advantages. Because of the limitation of the present researches, it needs a large scale of RCTs with rational design, high quality and proper methods to verify this research conclusion.
