Background The diseases of neuro-ophthalmology are common,which can influence the quality of patients' life seriously.The 39-item National Eye Institute Visual Function Questionnaire (NEI VFQ-39) is an instrument to assess self-reported visual impairment in studies of vision.However,until now,no studies have been performed to specifically assess the vision-related quality of life in persons with diseases of neuro-ophthalmology.Objective To evaluate vision-related quality of life for neuro-ophthalmology inpatients through the NEI VFQ-39,for the better treatment and nursing for them.Methods Ninety-seven neuro-ophthalmology inpatients were scheduled in research from June 1 to September 30,2012,and we collected all the clinical datas and the Chinese version NEI VFQ-39.The NEI VFQ-39 subscale item scores were compared among subgroups divided by monocular or binocular incidence,diseases and best corrected visual acuity(BCVA),and correlation analysis of the NEI VFQ-39 scores and BCVA for better-seeing and worse-seeing eyes was performed.Results The mean age of scheduled patients was (36.6±14.4)years,with no difference in gender.The mean composite score of VFQ-39 was 57.36(46.50,73.38),mental health subscale score was lowest [45.00 (35.00,60.00)].In the four eye diseases groups,except for eye pains,degree of dependence,periphery vision,anterior ischemic optic neuropathy (AION) group had lower scores compared with the other three groups,but there were no statistical significances among the four groups (all at P>0.05).Except for eye pains,patients with monocular incidence had better scores than those with binocular incidence,with statistical significant significances between them(all at P<0.05).Patients with BCVA in the better-seeing eye > 20/32 had better scores than the other two groups,compared with the BCVA in the better-seeing eye <20/200 group,except for overall health and eye pains,cornpared with the 20/200 ≤ BCVA in the better-seeing eye <20/23 group,except for eye pains,social activity and color vision,and the rest subscale scores had significant differences among the three groups(all at P<0.05).NEI VFQ-39 scores had positive correlations with the BCVA for better-seeing and worse-seeing eyes,and had strong correlations with the BCVA for better-seeing.Conclusions Neuro-ophthalmology diseases have serious influences on patients' visual function and quality of life.The quality of life has direct correlation with BCVA,so improving their visual function is helpful to their quality of life.

The purpose of this paper is to report the research and design of control system of magnetic coupling centrifugal blood pump in our laboratory, and to briefly describe the structure of the magnetic coupling centrifugal blood pump and principles of the body circulation model. The performance of blood pump is not only related to materials and structure, but also depends on the control algorithm. We studied the algorithm about motor current double-loop control for brushless DC motor. In order to make the algorithm adjust parameter change in different situations, we used the self-tuning fuzzy PI control algorithm and gave the details about how to design fuzzy rules. We mainly used Matlab Simulink to simulate the motor control system to test the performance of algorithm, and briefly introduced how to implement these algorithms in hardware system. Finally, by building the platform and conducting experiments, we proved that self-tuning fuzzy PI control algorithm could greatly improve both dynamic and static performance of blood pump and make the motor speed and the blood pump flow stable and adjustable.

Head and neck squamous cell carcinoma(HNSCC) is among the most common malignances worldwide.Patients with HNSCC often develop primary tumors at multiple sites and have tendency for local recurrences following curative resectional surgery.Field cancerization theory presumes that,after repeated carcinogenic exposures,the entire superficialepitheliium of the upper aerodigestive tract has an increased risk for developing (pre)malignant lesions because of multiple genetic abnormalities.This theorywell explains the strong potential with malignant transformation and loco-regional recurrence in HNSCC,and helps to better understand the pathogenesis,and thus provides a new idea for prevention and treatment of this disease.This paper will give an overview of field cancerization,including the concept and its clinical application.

Objective:To investigate the effects of long-term X-ray radiation exposure on the tumor risk of medical X-ray workers in Jiangsu province, and to provide a scientific basis for the development of occupational protection policies and the improvement of workers′ health.Methods:By using a combination of retrospective and prospective cohort research method, the medical diagnostic X-ray workers who worked in the radiology department of all hospitals in Jiangsu province between 1950 and 1980 were selected as the radiology group.In the meantime medical personnel in internal medicine, otorhinolaryngology, pediatrics and other medical departments who had not been engaged in radiology during the same period of time at the same hospital were selected as the control group to form a survey cohort. The cumulative number of person-years of observation of the cohort during 1950-2011 was calculated, and the relative risk of various malignant tumors among medical X-ray workers was calculated by using Cox regression model after adjusting for sex, attained age, year of birth, and year of work initiation.Results:A total of 6 954 follow-ups was completed for the cohort, including 3 649 in the irradiation group and 3 305 in the control group, totally 340 483 person-years of observation. As of December 31, 2021, there were 1 328 patients with malignant tumors in this cohort. Cox regression result showed that compared with the control group, the irradiation group who had developed lung cancer ( RR=1.60, 95% CI 1.24-2.08), lymphoma ( RR =4.28, 95% CI 1.54-11.93), solid cancer ( RR =1.17, 95% CI 1.04-1.31), and total cancer ( RR =1.29, 95% CI 1.14-1.46) had significantly higher relative risks ( Z=3.56, 2.78, 2.71, 3.96, P<0.05). Stratified analyses showed that the risks of lung, lymphoma, solid and total cancers were higher in the radiation group than in the control group for males and for those who arrived at the age of 61 years or older ( χ2=6.70-33.86, P<0.05). The risks of lung, solid and total cancers were higher in the radiation group than in the control group for those who started to work in the age group of 21 to 25 years ( χ2=6.46, 6.16, 5.62, P<0.05). Conclusions:The relative risks of lung, lymphoma, solid and total cancers among medical X-ray workers in Jiangsu province are significantly higher, suggesting that attention should be paid to strengthening radiation protection for radiation workers in their radiological practices.

Objective:To investigate the relationship between hepatic venous pressure gradient (HVPG) and parameters of Doppler ultrasound in patients with pyrroidine alkaloid-related hepatic sinusoidal obstruction syndrome (PA-HSOS).Methods:From February 17, 2017 to April 22, 2020, the clinical data of 68 patients with PA-HSOS who underwent HVPG manometry and Doppler ultrasound examination at Drum Tower Hospital, the Affiliated Medical College of Nanjing University were retrospectively analyzed, which included HVPG, Drum Tower severity scoring (DTSS), time from PA-HSOS related symptoms appeared to diagnosis after taking pyrroidine alkaloid (hereinafter referred to as diagnosis time), and parameters of Doppler ultrasound induding portal vein trunk diameter (PD), peak portal vein velocity (PPV), splenic vein trunk diameter (SD) and peak splenic vein velocity (PSV). Receiver operating characteristic curve (ROC) was used to determine the optimal cut-off value of HVPG for predicting non-response to anticoagulation therapy. Binary logistic regression was used to analyze the independent risk factors for non-response to anticoagulation therapy, and Kaplan-Meier survival curve was used to analyze the prognostic survival rate of patients with different HVPG levels. Unitary linear regression was applied to analyze the correlation of HVPG with PD, PPV, SD and PSV in patients with different HVPG levels, patients with mild, moderate and severe DTSS, and patients with diagnosis time >1 month or ≤ 1 month. Chi-square test was used for statistical analysis.Results:The results of ROC analysis showed that the optimal cut-off value of HVPG for predicting non-response to anticoagulant therapy was 20.165 mmHg(1 mmHg=0.133 kPa). The result of multivariate analysis indicated that high HVPG (HVPG>20.165 mmHg) was an independent risk factor for predicting non-response to anticoagulant therapy ( OR (95% confidence interval)=6.039(1.466 to 24.869), P=0.013). Kaplan-Meier survival curve demonstrated that prognostic survival rate of patients with high HVPG was lower than that of patients with low HVPG (HVPG≤20.165 mmHg) (78.4% vs.96.8%), and the difference was statistically significant( χ2=4.74, P=0.030). The results of unitary linear regression analysis showed that there was a negative correlation between HVPG and PPV in 68 patients with PA-HSOS( r=-0.330, P=0.006); HVPG was positively correlated with PD and SD in patients with high HVPG ( r=0.540 and 0.341, P=0.001 and 0.039); there was a negative correlation between HVPG and PSV in patients with mild DTSS ( r=-0.519, P=0.019), HVPG was negatively correlated with PPV in patients with moderate DTSS ( r=-0.400, P=0.014). In patients with diagnosis time ≤1 month, there was a negative correlation between HVPG and PPV ( r=-0.391, P=0.010). Conclusions:HVPG can assist in judging the response to anticoagulation therapy and the prognosis of patients with PA-HSOS. Parameters of Doppler ultrasound can help to assess the degree of HVPG elevation in patients with PA-HSOS under certain conditions.

Severe traumatic brain injury (sTBI) as the most common emergency severe syndrome in neurosurgery has a high mortality and poor prognosis. Decompressive craniectomy is the first treatment choice for sTBI. The reverse question mark incision was usually adopted in decompressive craniectomy, but some scholars also suggest using the n-type incision and Kempe incision. Although the curative effect is remarkable when using the above incisions, the incidence of postoperative complications is high, such as cerebrospinal fluid leakage, poor wound healing and flap ischemic necrosis. Moreover, the advantages and disadvantages of different incisions are not clear. Therefore, some scholars proposed retroauricular incision decompressive craniectomy for sTBI patients because this incision that retains blood supply through a new flap can provide better decompression effect and reduce incision-related complications. The authors review the research progress in retroauricular incision in aspects of the methods, indications and its advantages and disadvantages in constrast with other incisions, so as to provide a theoretical basis for the selection of incision for decompressive craniectomy in sTBI patients.

Objective:To investigate the effects of Neibu Huangqi Decoction combined with Kangfuxin Liquid on wound healing after hemorrhoid fistula.Methods:Randomized controlled trial. A total of 90 patients with hemorrhoid fistula surgery in Tangshan Hospital of Traditional Chinese Medicine from January 2020 to June 2021 were selected as the observation objects and divided into 2 groups by random number table method, with 45 cases in each group. The control group was treated with Kangfuxin Liquid after surgery, and the observation group was treated with Neibu Huangqi Decoction. Both groups were treated continuously for 14 days. Wound symptom score was performed before and after treatment. The levels of TNF-α, IL-6 and IL-8 were determined by ELISA. The wound healing time was observed and the wound healing rate was calculated. Adverse reactions were recorded and clinical efficacy was evaluated.Results:The total effective rate was 93.33% (42/45) in the observation group and 66.67% (30/45) in the control group, with statistical significance ( χ2=9.89, P=0.002). After treatment, the scores of pain [(0.63±0.14) vs. (0.97±0.27), t=7.50], exudation [(0.67±0.12) vs. (1.09±0.31), t=8.48], edema [(0.78±0.17) vs.(1.25±0.36), t=7.92], pruritus [(0.78±0.20) vs. (1.32±0.33), t=9.39] were lower than those in the control group ( P<0.01); serum TNF-α [(33.46±2.86) μg/L vs. (45.78±3.92) μg/L, t=25.39], IL-6 [(41.86±5.84) μg/L vs. (56.12±6.75) μg/L, t=15.98], IL-8 [(27.40±3.58) ng/L vs. (36.16±3.84) ng/L, t=16.69] were lower than those in the control group ( P<0.01). The wound healing time of the observation group was shorter than that of the control group ( t=8.60, P<0.01), and the wound healing rate was higher than that of the control group ( t=24.65, P<0.01). During treatment, the incidence of adverse reactions was 11.11% (5/45) in the observation group and 6.67% (3/45) in the control group, without statistical significance ( χ2=0.14, P=0.711). Conclusion:Neibu Huangqi Decoction combined with Kangfuxin Liquid can promote wound healing, reduce inflammatory cytokines, relieve pain and exudation, improve clinical efficacy, and have few adverse reactions.
