Objective To evaluate the activities of daily living (ADL) and investigate its influential factor in primary angle-closure glaucoma patients.Methods One hundred primary angle-closure glaucoma patients (acute phase) diagnosed definitely from April to October 2014 were collected.The status of sex,gender,education,income were recorded.Barthel Index (BI),Hospital Anxiety and Depression Scale (HADS) and Glaucoma Quality of Life-15 (GQL-15) were respectively used to assess the ADL,anxiety and depression symptoms and visual quality of life in primary angle-closure glaucoma patients.At the same time the factors affecting ADL of primary angle-closure glaucoma were analyzed.Results There were no dysfunction in 12 patients,46 patients with mild dysfunction,32 patients with moderate dysfunction and 10％ (10/100) patients with severe dysfunction.BI was negatively correlated with anxiety and depression score,GQL-15 results and disease course (r=-0.819-0.395,P ＜ 0.01),and positively correlated with average monthly income (r=0.453,P ＜ 0.01).There were no correlation with gender,sex and education (r=-0.159-0.172,P ＞ 0.05).Conclusions ADL of primary angle-closure glaucoma patients has varying degrees of dysfunction,and disease course,average monthly income,anxiety,depression and visual quality of life are closely related with it.

Objective To investigate the prevention efficiency of spanishneedles herb eye drops on rabbit model with dry eye syndrome caused by sex hormones decline in peri-menopause. Methods Totally 26 rabbits ( 26 right eyes) with dry eye model were studied,and divided into two groups:group A ( the control group, n=12) and group B ( the spanishneedles herb eye drops group, n=12) ,another two rabbits were used as normal control.The Schirmer I tests (SIT), and corneal fluorescein ( FL) were detected, and the total protein content in tear, amylase activity, lactoferrin and lysozyme contents were measured and confocal scanning microscopy were performed at pre-therapy and 1 week,2 weeks,1 month,2 months after therapy,respectively. Results There were no significant difference in the total proteins,lysozyme,lactoferrin and amylase activity between two groups at pre-therapy (P>0.05).After 2 months treatment, there were statistical differences in all items of group A(P<0.05), and SIT, FL in group B(P<0.05).There were significant differences in all indexes between group A and B at 1 wk,2wk,1mo,2mo after therapy.After 2 months treatment,the mean numbers of corneal basal cell in the group B were significantly lower(3 452±422)than those in the group A ( 4 104 ± 568 ) ( P<0. 05 ) . The mean numbers of the inflammatory cells in the group B ( 42 ± 18 ) were significantly lower than those in the group A(208±69)( P<0.05). Conclusion Spanishneedles herb eye drops has significant prevention effect on dry eye syndrome caused by sex hormones decline in peri-menopause.

Objective:To investigate the associations between small diffusion-weighted imaging (DWI) hyperintensities lesions and total cerebral small vessel disease (cSVD) burden and the influence on prognosis in patients with acute intracerebral hemorrhage (ICH).Methods:Consecutive patients with acute spontaneous ICH from January 2018 to June 2021 were recruited in the Stroke Center of Zhengzhou People′s Hospital. Magnetic resonance imaging was performed to quantify DWI hyperintensities lesions and cSVD imaging markers, including white matter hyperintensities, enlarged perivascular spaces, lacunes and cerebral microbleeds, which were calculated for the total cSVD burden (0-4 points). The prognosis was assessed with the modified Rankin Scale (mRS) at discharge and 90-day. Multivariable Logistic regression models were adopted to explore the associations between DWI lesions and total cSVD burden and clinical outcome.Results:Of 283 included patients, 59 (20.8%) had small DWI lesions, 32 (11.3%) had multiple lesions. They were mostly punctate, mainly located in the cortical and subcortical regions, and scattered in multiple vascular territories. With the increase of cSVD burden, the number of DWI lesions gradually increased. Spearman correlation analysis showed that the total cSVD burden was positively correlated with the number of DWI lesions ( r=0.21, P<0.001). In multivariable regression analyses, the total cSVD burden was independently associated with DWI lesions ( OR=1.63, 95% CI 1.23-2.15, P=0.001). The 90-day poor outcome (mRS scores≥4) in patients with DWI lesions was significantly higher than those without DWI lesions (39.3% vs 16.3%, χ 2=14.38, P<0.001), while there was no statistically significant difference in the poor outcome of discharge between the two groups (26.5% vs 17.7%, χ 2=3.06, P=0.080). With the increase in the number of DWI lesions, the 90-day poor outcome increased significantly (trend chi-squared test χ 2=11.50, P=0.001). Multivariable analyses showed that DWI lesions ( OR=4.39, 95% CI 1.92-10.03, P<0.001) and their number ( OR=1.42, 95% CI 1.06-1.90, P=0.018) were independently associated with the 90-day poor outcome. Conclusions:Higher total cSVD burden is an independent risk factor for small DWI lesions in patients with ICH. Small DWI lesions were independently associated with the 90-day poor outcome, but not with the discharge outcome.

Objective To investigate distribution and antimicrobial resistance among nosocomial pathogens from 13 teaching hospitals in China in 2009. Methods Non-repetitive pathogens from nosocomial BSI, HAP and IAI were collected and sent to the central lab for MIC determination by agar dilution method.WHONET5.6 software was used to analyze the data. Results A total of 2 502 clinical isolates were collected. The top three pathogens of BSI were Escherichia coli [27. 1% (285/1 052 )] , coagulase-negutive staphylococcus [12. 6% ( 133/1 052)] and Klebsiella pneumoniae [10. 8% ( 114/1 052)]. The top three pathogens of HAP were Acinetobacter baumannii [28. 8% (226/785)], Pseudomonas aeruginosa [16. 1% (126/785)] and Klebsiella pneumoniae [14.6% (115/785 )] . The top three pathogens of IAI were Escherichia coli[31.0% ( 206/665 )], Klebsiella pneumonia [11.3% ( 75/665 )] and Enterococcus faecium [10. 8% (72/665)]. Against Escherichia coil and Klebsiella spp. , the antimicrobial agents with higher than 80% susceptibility rate included imipenem and meropenem (98. 1%-100% ), tigecycline (95.3%-100% ), piperacillin-tazobactam ( 88.6% -97. 1% ) and amikacin ( 88. 3% -92. 5% ). Against Enterobacter spp. , Citrobacter spp. and Serratia spp. , the susceptibility rates of tigecycline were 93.5% -100% whereas the value of imipenem and meropenem were 92.9% -100%. Other antimicrobial agents with high activity included amikacin ( 85.2% -96. 7% ), pipcracillin-tazobactam ( 82.4% -96.4% ), cefepime ( 79. 6% -96. 7% ) and cefoperazonc-sulbactam (78. 7%-90. 0% ). Polymyxin B showed the highest susceptibility rateagainst Pseudomonas aeruginosa ( 100% ), followed by amikacin ( 81.9% ) and piperacillin-tazobactam (80.1% ). Polymyxin B also showed the highest susceptibility rate against Acinetobacter baumannii (98. 8% ), followed by tigecycline (90. 1% ) and minocycline (72. 0% ). The incidence of carbapenemresistant Acinetobacter baumannii was 60. 1%. The MRSA rate was 60. 2% and the MRSCoN rate was 84. 2%. All Staphylococcus strains were susceptible to tigecycline, vancomycin, teicoplanin and linezolid except for one isolate of Staphylococcus haemolysis with intermediate to teicoplanin. Two Enterococcus faecalis isolates which were intermediate to linezolid and one Enterococcus faecium isolate which was resistant to vancomycin and teicoplanin was found in this surveillance, while the MICs of tigecycline against these three isolates were 0. 032-0. 064 μg/ml. Conclusions Tigecycline, carbapenems, piperacillin-tazobactam,amikacin and cefepime remain relatively high activity against nosocomial Enterobacteriaceae. Pseudomonas aeruginosa exhibite high susceptibility to polymyxin B, while Acinetobacter baumanni shows high susceptibility to polymyxin B and tigecycline. Tigecycline, vancomycin, teicoplanin and linezolid remain high activity against nosocomial gram-positive cocci.

Objective: To evaluate clinical characteristics and prognosis of primary myelofibrosis (PMF) patients with thrombocytopenia in varied degrees. Methods: Clinical features and survival data of 1 305 Chinese patients with PMF were retrospectively analyzed. The prognostic value of thrombocytopenia in patients with PMF was evaluated. Results: 320 subjects (47%) presented severe thrombocytopenia (PLT<50×10⁹/L), 198 ones (15.2%) mild thrombocytopenia [PLT (50-99)×10⁹/L] and 787 ones (60.3%) without thrombocytopenia (PLT ≥ 100×10⁹/L). The more severe the thrombocytopenia, the higher the proportions of HGB<100 g/L, WBC<4×10⁹/L, circulating blasts ≥ 3%, abnormal karyotype and unfavourable cytogenetics (P<0.001, P<0.001, P=0.004, P<0.001 and P<0.001, respectively) were observed in this cohort of patients. The more severe the thrombocytopenia, the lower the proportion of JAK2V617F positive (P<0.001) was also noticed. Platelet count was positively correlated with splenomegaly, HGB and WBC (P<0.001, correlation coefficients were 0.131, 0.445 and 0.156, respectively). Platelet count was negative correlated with constitutional symptoms and circulating blasts (P=0.009, P=0.045, respectively; correlation coefficients were -0.096 and -0.056, respectively). The median survival of patients with severe thrombocytopenia, mild thrombocytopenia and without thrombocytopenia were 32, 67 and 89 months, respectively (P<0.001). Multivariate analysis identified thrombocytopenia in varied degrees (HR=1.693, 95%CI 1.320-2.173, P<0.001) and Dynamic Internation Prognostic Scoring System(DIPSS) prognostic model (HR=2.051, 95%CI 1.511-2.784, P<0.001) as independent risk factors for survival. Conclusion PMF patients with severe thrombocytopenia frequently displayed anemia, leucopenia, circulating blasts and short survival, so active treatment measures should be taken especially in these patients.

Objective:To investigate the value of a nomogram predicting the outcome of intracerebral hemorrhage (ICH) based on clinical characteristics and diffusion-weighted imaging (DWI) of hyperintense lesions.Methods:A case-control study. Consecutive patients, aged 30-88(59±13) years old, with ICH were recruited at the Stroke Center of Zhengzhou People′s Hospital from January 2018 to August 2021. Patients were divided into a group with DWI lesions and a group without DWI lesions depending on whether there were DWI hyperintense lesions distant from the hematoma. Prognosis was evaluated at 90 days via the modified Rankin Scale (mRS). Univariate and multivariable logistic regression models were used to identify independent predictors of a poor ICH outcome (mRS score≥4), and a nomogram model was developed. The performance of the nomogram was validated via the area under the receiver operating characteristic curve (AUC) and a calibration chart.Results:Of the 303 patients included in the study, 24.8% presented with DWI lesions; 17.5% with asymptomatic DWI lesions and 7.3% with symptomatic DWI lesions. Poor outcomes were significantly more frequent in the group with DWI lesions than in the group without DWI lesions ( χ2=21.32, P<0.001). In multivariable regression analysis, age [odds ratio ( OR)=1.032, 95% confidence interval ( CI) 1.002-1.063, P=0.035], hematoma volume ( OR=1.050, 95% CI 1.011-1.090, P=0.012), hematoma location ( OR=3.839, 95% CI 1.248-11.805, P=0.019), DWI lesions ( OR=3.955, 95% CI 1.906-8.206, P<0.001), and baseline NIHSS scores ( OR=1.102, 95% CI 1.038-1.170, P=0.001) were independent predictors of a poor outcome. In subgroup analysis patients with asymptomatic DWI lesions had a 3-fold greater risk of a poor outcome compared to those without DWI lesions ( OR=3.135, 95% CI 1.382-7.112, P=0.006), and patients with symptomatic DWI lesions had a 7-fold greater risk of a poor outcome compared to those without DWI lesions ( OR=7.126, 95% CI 2.279-22.277, P=0.001). A nomogram model was established based on the independent predictors for a poor outcome. The AUC of the nomogram was 0.846 (95% CI 0.795-0.898), and a calibration chart indicated good consistency between values predicted by the nomogram and actual observed values. Conclusions:DWI lesions are an independent risk factor for a poor outcome in patients with ICH-particularly symptomatic DWI lesions. A nomogram model based on clinical characteristics and DWI lesions exhibited good efficacy when predicting the outcome of ICH.

OBJECTIVETo evaluate the prognostic value of cytogenetics in Chinese with primary myelofibrosis (PMF).

METHODSFour hundred and thirty-nine Chinese patients with PMF were retrospectively analyzed. The Kaplan-Meier method, the Log-rank test, the likelihood ratio test and the COX proportional hazards regression model were used to evaluate the prognostic scoring systems.

RESULTSFour hundred and thirty-nine Chinese patients with PMF were analyzed with a median age of 56 years (range: 8-83), including 298 males and 141 females. The DIPSS-plus system could effectively evaluate prognosis in Chinese patients with PMF. There was significantly higher predictive power for survival for the DIPSS-plus group compared with the DIPSS group (P=0.006, -2 log-likelihood ratios of 989.5 and 1001.9 for the DIPSS-plus and DIPSS systems, respectively). Univariate analysis indicated that the patients with a normal karyotype, a complex karyotype that was not a monosomal karyotype, +8 only or a balanced translocation only had better survival. Following two cytogenetic risk categories were constructed: favorable karyotype including subjects with a normal karyotype, a complex karyotype that was not a monosomal karyotype, +8 only or a balanced translocation only and unfavorable karyotype included all others. The modified DIPSS-Chinese prognostic model was proposed by adopting cytogenetic categories and DIPSS- Chinese risk group. The median survival of patients classified in low risk (163 subjects), intermediate-1 risk (187 subjects), intermediate-2 risk (82 subjects) and high risk (7 subjects) were not reached, 74 (95% CI 42-106), 39 (95% CI 26-52) and 12(95% CI 1-25)months, respectively, and there was a statistically significant difference in overall survival among the four risk groups (P<0.01).

CONCLUSIONThe DIPSS-plus had significantly higher predictive power than the DIPSS group in Chinese patients with PMF and the modified DIPSS-Chinese system based on the cytogenetic features of Chinese patients was proposed and worked well for prognostic indication.

BACKGROUND: The relationship between quality of life at three months after lung cancer surgery and different surgical approaches is remains unclear. This study aimed to compare the quality of life of patients three months after uniportal and multiportal thoracoscopic lobectomy. METHODS: Data from patients who underwent lung surgery at the Department of Thoracic Surgery, Sichuan Cancer Hospital between April 2021 and October 2021 were collected. The European Organization for Research and Treatment of Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30) and Quality of Life Questionnaire-Lung Cancer 29 (EORTC QLQ-LC29) were used to collect quality of life data of the patients. Potential confounding factors in the baseline data were included in a multivariate regression model for adjustment, and the quality of life of the two groups three months postoperatively was compared with traditional clinical outcomes. RESULTS: A total of 130 lung cancer patients were included, with 57 males (43.8%) and 73 females (56.2%), and an average age of (57.1±9.5) yr. In the baseline data of the two groups, there was a statistical difference in the number of chest drainage tubes placed (P<0.001). After adjustment with the regression model, at three months postoperatively, there were no significant differences in all symptoms and functional status scores between the two groups (all P>0.05). The multiportal group had longer surgery time (120.0 min vs 85.0 min, P=0.001), postoperative hospital stay (6.0 d vs 4.0 d, P=0.020), and a higher incidence of early ≥ grade 2 complications (39.0% vs 10.1%, P=0.011) compared to the uniportal group. CONCLUSIONS Patients undergoing uniportal and multiportal thoracoscopic lobectomy have similar quality of life at three months postoperatively. The uniportal group may have certain advantages in terms of traditional clinical outcome indicators such as operation time, postoperative hospital stay, and early postoperative complications.

Telephone follow-up is one of the important ways to follow up patients. High-quality follow-up can benefit both doctors and patients. However, clinical research-related follow-up is often faced with problems such as time-consuming, laborious and poor patient compliance. The authors belong to a team that has been committed to the study of patient-reported outcomes for a long time. The team has carried out long-term follow-up of symptoms, daily function and postoperative complications of more than 1 000 patients after lung cancer surgery, and accumulated certain experience. In this paper, the experience of telephone follow-up was summarized and discussed with relevant literatures from the aspects of clarifying the purpose of clinical research follow-up, understanding the needs of patients in follow-up, and using follow-up skills.
