AIM: To investigate the influence of relevant inflammatory markers in peripheral blood on the progression of neovascular glaucoma(NVG)secondary to diabetic retinopathy(DR)patients.METHODS: Retrospective case-control study. Patients were categorized into two groups based on the presence or absence of NVG: those with proliferative diabetic retinopathy(PDR)alone(PDR group, n=148)and those with NVG secondary to PDR(NVG secondary to PDR group, n=142). Peripheral blood inflammatory markers were evaluated, including white blood cell-related indices, neutrophil-to-lymphocyte ratio(NLR), platelet-to-lymphocyte ratio(PLR), monocyte-to-lymphocyte ratio(MLR), and systemic immune-inflammation index(SII). The distinctions in peripheral blood inflammatory markers between the two groups of patients and their relationships with NVG secondary to PDR were analyzed.RESULTS:No statistically significant differences were observed in basic characteristics between the two groups, confirming their comparability. However, significant differences were found in eosinophil percentage and MLR between the PDR group and the NVG secondary to PDR group(all P<0.05), with both values being significantly higher in the NVG secondary to PDR group. Multivariate Logistic regression analysis revealed that the eosinophil percentage and the MLR were factors influencing the development of patients with NVG secondary to PDR.CONCLUSION: Eosinophil percentage and MLR may be associated with the progression of PDR to NVG, and could serve as potential predictive markers for NVG development in PDR patients.

Objective: To investigate the attention cognitive function and symptom correlations of school aged children with attention deficit hyperactivity disorder (ADHD)using event related potential (ERP) technology, so as to provide references for the early diagnosis of children with ADHD. Methods: A total of 52 school aged children diagnosed with ADHD at the outpatient department of the Third Affiliated Hospital of Zhengzhou University from September 2022 to September 2024 and 50 age /sex matched healthy controls were selected. The ERP experiment adopted the auditory Oddball task to conduct comparative analyses of the amplitude and latency of the mismatch negative(MMN) at the Fz, Cz, and Pz points of the scalp electrode and the P3a component respectively. The symptom assessment scales adopted the Swanson,Nolan,and Pelham-Ⅳ Rating Scale (SNAP-Ⅳ) and the Parent Symptom Questionnaire (PSQ), which were filled out by the parents. Spearman correlation analysis was used to analyze the correlation between ERP components and symptoms in schoolaged children with ADHD. Results: The latency of MMN components in the healthy control group on the Fz lead was (188.30±2.06)ms, and the amplitude was (-15.54±1.35)μV; the latency of the P3a component on the Pz lead was (312.82±7.80)ms, and the amplitude was (3.80±0.18)μV. The latency of MMN components in the ADHD group on the Fz lead was (188.94±1.39)ms, and the amplitude was (-14.78±1.40)μV; the latency of the P3a component on the Pz lead was (317.21±5.65)ms, and the amplitude was (3.70±0.13)μV. Compared with normal children, the MMN of children with ADHD had smaller amplitudes in the Fz and Cz leads, and the P3a had greater latency and smaller amplitudes in the Cz and Pz leads ( t =2.79,2.20；-2.04，-3.25；2.35,3.21， P <0.05). Correlation analysis showed that the latency of MMN in children with ADHD was positively correlated with the inattention score in the SNAP-Ⅳ( r =0.22), and the amplitude of MMN was negatively correlated with the inattention score in the SNAP-Ⅳ and the learning problem score in PSQ ( r = -0.26 , -0.34)( P <0.05). The latency of P3a was positively correlated with the scores of inattention in the SNAP-Ⅳ and the score of learning problems in the PSQ ( r =0.26 ,0.24); the amplitude of P3a was negatively correlated with the scores of attention deficit and hyperactivity/impulsivity in the SNAP-Ⅳ and the scores of learning problems and impulsivity/hyperactivity in the PSQ( r = -0.26 , -0.22, -0.25,-0.32)( P <0.05). Conclusions School aged ADHD children exhibit abnormal MMN/P3a components, indicating attention related cognitive dysfunction. Symptoms such as inattention, learning problems and hyperactivity/impulsivity in children with ADHD are related to abnormal components of MMN and P3a.

Background: Cervical cancer is still present a major public health problem, especially in developing countries. In International Federation of Gynaecology and Obstetrics 2018, allowing assessment of retroperitoneal lymph nodes by imaging and/or pathological findings and, if deemed metastatic, the case is designated as stage IIIC (with r and p notations). Patients with lymph node metastases have lower overall survival (OS), progression free survival (PFS), and survival after recurrence, especially those who have unresectable macroscopical positive lymph nodes. Retrospective analysis suggests that there may be a benefit to debulking macroscopic nodes that would be otherwise difficult to sterilize with standard doses of radiation therapy. However, there are no prospective study reporting that resecting macroscopic nodes before concurrent chemoradiation therapy (CCRT) would improve PFS or OS of cervical cancer and no guidelines for surgical resection of bulky lymph nodes. The CQGOG0103 study is a prospective, multicenter and randomized controlled trial (RCT) evaluating lymph node dissection on stage IIICr of cervical cancer. Methods Eligible patients are histologically confirmed cervical squamous cell carcinoma, adenocarcinoma, adeno-squamous cell carcinoma. Stage IIICr (confirmed by computed tomography [CT]/magnetic resonance imaging/positron emission tomography/CT) and the short diameter of image-positive lymph node ≥15 mm. 452 patients will be equally randomized to receive either CCRT (pelvic external-beam radiotherapy [EBRT]/extended-field EBRT + cisplatin [40 mg/m2] or carboplatin [the area under curve=2] every week for 5 cycles + brachytherapy) or open/minimally invasive pelvic and para-aortic lymph node dissection followed by CCRT. Randomization is stratified by status of para-aortic lymph node. The primary endpoint is PFS. Secondary endpoints are OS and surgical complications. A total of 452 patients will be enrolled from multiple hospitals in China within 4 years and followed up for 5 years.

Objective:To evaluate the difference of dosimetry between three-dimensional and two-dimensional plans based on CT images of occult perforation in brachytherapy of cervical cancer, aiming to provide clinical reference.Methods:A total of 817 patients with cervical cancer received simple intrauterine (intrauterine tandem plus vaginal colpostats) three-dimensional brachytherapy in Chongqing University Cancer Hospital from January 2019 to December 2020 were retrospectively reviewed. Among them, 16 patients had occul uterine perforation. Based on Oncentra Brachy Therapy plan system, the single prescription dose was 6Gy. Three-dimensional (3D group) and two-dimensional (2D group) plans were designed on the perforated CT images The target volume, conformal index (CI), conformal index coformity index (COIN) and organs-at-risk (OAR) D 2cm 3 parameters were used to assess the plans between two groups. Results:The incidence of pccult uterine perforation was 1.96%(16/817) during brachytherapy for cervical cancer. The volume of prescription dose curve in the 3D group was (40.74±14.98) cm 3, significantly smaller compared with (91.46±19.71) cm 3 in the 2D group ( P<0.05), whereas the volume of the high-risk clinical target area wrapped by prescription dose curve did not significantly differ between two groups ( P>0.05). The CI and COIN in the 3D group were 0.79±0.10 and 0.72±0.96, significantly higher compared with 0.38±0.09 and 0.37±0.18 in the 2D group (both P<0.05). The D 2cm 3 of bladder, rectum, sigmoid colon, small intestine in the 3D group were (306.06±77.57) cGy, (252.27±72.60) cGy, (127.25±62.84) cGy and (228.79±94.90) cGy, significantly lower than (548.03±164.21) cGy, (411.16±118.74) cGy, (227.45±94.48) cGy and (450.95±157.96) cGy in the 2D group (all P<0.05). Conclusions:Application of image guidance in brachytherapy of cervical cancer is helpful to detect occult uterine perforation. When occult uterine perforation occurs, the use of three-dimensional plan can basically meet the clinical needs, which is significantly better than the two-dimensional plan.

Non-small cell lung cancer (NSCLC) is the most common pathological type of primary lung cancer. Currently, main treatment approaches for NSCLC patients include surgical resection, radiotherapy, chemotherapy, targeted therapy and so on. In recent years, thermal ablation has received increasing attention in the treatment of various stages of NSCLC. As a safe and efficient local treatment, thermal ablation may bring potential clinical benefits to NSCLC patients. However, many issues remain unsolved and further investigation is needed in the clinical application of thermal ablation in NSCLC. In this review, we aim to summarize the applications of thermal ablation in NSCLC and further discuss the emerging controversies as well as future research directions.

Objective:To observe the efficacy of meglumine adenosine cyclophosphate (MAC) in the adjuvant treatment of chronic congestive heart failure(CHF) in the elderly, and its effects on cystatin C(Cys-C) and plasma B-type natriuretic peptide(BNP).Methods:From August 2017 to August 2018, 110 elderly patients with chronic CHF admitted to Zhejiang Provincial Armed Police Corps Hospital were selected and randomly divided into control group(55 cases) and observation group(55 cases) by random number table method.The control group was treated with routine treatment, while the observation group was treated with MAC on the basis of routine treatment.Both two groups were treated for 2 weeks.The clinical efficacy, left ventricular ejection fraction (LVEF), cardiac output, Cys-C and plasma BNP were compared between the two groups.Results:The total improvement rate of the observation group was 94.55%(52/55), which was higher than 78.18%(43/55) of the control group, the difference was statistically significant(χ 2=6.253, P<0.05). Before treatment, there were no statistically significant differences in LVEF, cardiac output, BNP and Cys-C between the two groups(all P>0.05). After treatment, the LVEF[(44.16±6.82)%], cardiac output[(8.07±1.45)L/min] of the observation group were significantly higher than those of the control group[(40.71±5.38)%, (6.44±1.37)L/min], and BNP[(1.65±0.24)mg/L], Cys-C[(552.79±10.46)mg/L] of the observation group were significantly lower than those of the control group[(2.31±0.48)mg/L, (681.73±12.71)mg/L], the differences were statistically significant( t=2.945, 6.060, 9.121, 0.551, all P<0.05). Conclusion:MAC has significant effect in the treatment of elderly patients with chronic CHF.It can improve the cardiac function of patients and reduce the plasma concentrations of Cys-C and BNP.

Objective: To discuss the application of bedside ultrasound monitoring of gastric residual volume in ICU patients complicated with enteral nutrition support via nasogastric tube. Methods: November 2017 to May 2018, 120 patients with enteral nutrition support via nasogastric tube who admitted in ICU of our hospital were randomly divided into the observation group and the control group. The observation group used bedside ultrasound monitoring to determine the gastric residual volume, while the control group was estimated by withdrawn with 50 ml syringe. Reflux, pulmonary aspiration and the time of enteral nutrition were observed in both groups. Results: Reflux and pulmonary aspiration were present in 2, 3 in the observation group and 10, 11 in the control group, with significant difference between them (χ²=4.53, 3.96, P<0.05). The time of enteral nutrition in the observation group was (13.98±3.20) h, and (15.54±3.54) h in the control group, which had a statistically difference (t=-10.49, P<0.05). Conclusion The application of bedside ultrasound monitoring of gastric residual volume in ICU patients complicated with enteral nutrition support via nasogastric tube can significantly reduce the risk of reflux and pulmonary aspiration which can ensure the safety of enteral nutrition, and decrease time of enteral nutrition.

Objective:To explore the effects of humanized nursing and personalized service in operating room nursing.Methods:A total of 300 patients who underwent surgical surgery in our hospital from April 2016 to June 2016 were randomly divided into the intervention group (n =150) and control group (n =150).Patients in the control group were treated with routine nursing care.On this basis,patients in the intervention group were provided with integral perioperative nursing of humanized nursing and personalized service.The fear,anxiety,blood pressure and heart rate fluctuations of both two groups before and after entering operating room were statistically analyzed.Results:Before entering operating room,the fear and anxiety scores of the patients in the intervention group were (32.67 ± 12.27),the blood pressure was (97.5 ± 12.8) mmHg,and the heart rate was (93.7 ± 11.8).The fear and anxiety scores in the control group were (36.94 ± 12.78),the blood pressure was (99.8 ± 12.5) mmHg,and the heart rate was (105.4 ± 10.6).The intervention group was significantly lower than the control group (P ＜ 0.05).Conclusion:The implementation of humanized nursing and personalized service can effectively reduce the patient's fear and anxiety to make the heart rate,blood pressure and other vital signs be in a relatively stable state;can make patients calm,positive and optimistic to undergo the surgery and actively cooperate with doctors and ward nursing,thus to get well soon.
