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 analyze the clinical features of postpartum hepatitis flares in pregnant women with hepatitis B virus (HBV) infection.Methods:A retrospective study was conducted. Patients who met the enrollment criteria were included. Liver function and HBV virology tests were collected from pregnant women with chronic HBV infection at delivery, 6, 24, 36, and 48 weeks after delivery through the hospital information and test system. Additionally, antiviral therapy types and drug withdrawal times were collected. Statistical analysis was performed on all the resulting data.Results:A total of 533 pregnant women who met the inclusion criteria were included, with all patients aged (29.5±3.7) years old. A total of 408 cases received antiviral drugs during pregnancy to interrupt mother-to-child transmission. There was no significant difference in the levels of alanine aminotransferase (ALT, z ?=?-1.981, P ?=?0.048), aspartate aminotransferase (AST, z ?=?-3.956, P ?

Objective:To investigate the value of systemic inflammatory response syndrome (SIRS), pediatric sequential organ failure assessment (pSOFA) and pediatric critical illness score (PCIS) in predicting mortality of pediatric sepsis in pediatric intensive care units (PICU) from Southwest China.Methods:This was a prospective multicenter observational study. A total of 447 children with sepsis admitted to 12 PICU in Southwest China from April 2022 to March 2023 were enrolled. Based on the prognosis, the patients were divided into survival group and non-survival group. The physiological parameters of SIRS, pSOFA and PCIS were recorded and scored within 24 h after PICU admission. The general clinical data and some laboratory results were recorded. The area under the curve (AUC) of the receiver operating characteristic curve was used to compare the predictive value of SIRS, pSOFA and PCIS in mortality of pediatric sepsis.Results:Amongst 447 children with sepsis, 260 patients were male and 187 patients were female, aged 2.5 (0.8, 7.0) years, 405 patients were in the survival group and 42 patients were in the non-survival group. 418 patients (93.5%) met the criteria of SIRS, and 440 patients (98.4%) met the criteria of pSOFA≥2. There was no significant difference in the number of items meeting the SIRS criteria between the survival group and the non-survival group (3(2, 4) vs. 3(3, 4) points, Z=1.30, P=0.192). The pSOFA score of the non-survival group was significantly higher than that of the survival group (9(6, 12) vs. 4(3, 7) points, Z=6.56, P<0.001), and the PCIS score was significantly lower than that of the survival group (72(68, 81) vs. 82(76, 88) points, Z=5.90, P<0.001). The predictive value of pSOFA (AUC=0.82) and PCIS (AUC=0.78) for sepsis mortality was significantly higher than that of SIRS (AUC=0.56) ( Z=6.59, 4.23, both P<0.001). There was no significant difference between pSOFA and PCIS ( Z=1.35, P=0.176). Platelet count, procalcitonin, lactic acid, albumin, creatinine, total bilirubin, activated partial thromboplastin time, prothrombin time and international normalized ratio were all able to predict mortality of sepsis to a certain degree (AUC=0.64, 0.68, 0.80, 0.64, 0.68, 0.60, 0.77, 0.75, 0.76, all P<0.05). Conclusion:Compared with SIRS, both pSOFA and PCIS had better predictive value in the mortality of pediatric sepsis in PICU.

Background Air pollution is a major public health concern. Air Quality Health Index (AQHI) is a very important air quality risk communication tool. However, AQHI is usually constructed by single-pollutant model, which has obvious disadvantages. Objective To construct an AQHI based on the joint effects of multiple air pollutants (J-AQHI), and to provide a scientific tool for health risk warning and risk communication of air pollution. Methods Data on non-accidental deaths in Yunnan, Guangdong, Hunan, Zhejiang, and Jilin provinces from January 1, 2013 to December 31, 2018 were obtained from the corresponding provincial disease surveillance points systems (DSPS), including date of death, age, gender, and cause of death. Daily meteorological (temperature and relative humidity) and air pollution data (SO₂, NO₂, CO, PM_2.5, PM₁₀, and maximum 8 h O₃ concentrations) at the same period were respectively derived from China Meteorological Data Sharing Service System and National Urban Air Quality Real-time Publishing Platform. Lasso regression was first applied to select air pollutants, then a time-stratified case-crossover design was applied. Each case was matched to 3 or 4 control days which were selected on the same days of the week in the same calendar month. Then a distributed lag nonlinear model (DLNM) was used to estimate the exposure-response relationship between selected air pollutants and mortality, which was used to construct the AQHI. Finally, AQHI was classified into four levels according to the air pollutant guidance limit values from World Health Organization Global Air Quality Guidelines (AQG 2021), and the excess risks (ERs) were calculated to compare the AQHI based on single-pollutant model and the J-AQHI based on multi-pollutant model. Results PM_2.5, NO₂, SO₂, and O₃ were selected by Lasso regression to establish DLNM model. The ERs for an interquartile range (IQR) increase and 95% confidence intervals (CI) for PM_2.5, NO₂, SO₂ and O₃ were 0.71% (0.34%–1.09%), 2.46% (1.78%–3.15%), 1.25% (0.9%–1.6%), and 0.27% (−0.11%–0.65%) respectively. The distribution of J-AQHI was right-skewed, and it was divided into four levels, with ranges of 0-1 for low risk, 2-3 for moderate risk, 4-5 for high health risk, and ≥6 for severe risk, and the corresponding proportions were 11.25%, 64.61%, 19.33%, and 4.81%, respectively. The ER (95%CI) of mortality risk increased by 3.61% (2.93–4.29) for each IQR increase of the multi-pollutant based J-AQHI , while it was 3.39% (2.68–4.11) for the single-pollutant based AQHI . Conclusion The J-AQHI generated by multi-pollutant model demonstrates the actual exposure health risk of air pollution in the population and provides new ideas for further improvement of AQHI calculation methods.

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 explore the role of constructivism teaching theory combined with problem-based learning (PBL) teaching mode in the training of new nurses in the department of gastroenterology.Methods:A total of 27 newly recruited nurses in the Department of Gastroenterology in West China Hospital of Sichuan University from August 2018 to August 2019 were selected as the control group, and traditional teaching was adopted. In addition, 24 newly recruited nurses from September 2019 to September 2020 were selected as the research group, using constructivism teaching theory combined with PBL teaching mode. After the training, the teaching effect was compared between the two groups through the assessment results and the training method scores. SPSS 19.0 was used for t test. Results:The research group's newly recruited nurses' theoretical evaluation scores [(95.08±5.61) vs. (91.63±5.27)] and practical skills operation evaluation scores [(94.30±7.22) vs. (87.13±6.84)] were both higher than those of the control group, and the difference was statistically significant ( P<0.05). Compared with the control group, the newly recruited nurses of the research group believed that the combination of constructivism teaching theory and PBL teaching could improve clinical thinking ability, analysis and problem-solving ability, and the degree of integration of theory and practice, mobilize the enthusiasm of autonomous learning, enhance autonomous learning ability, and improve communication ability, cultivate teamwork ability, stimulate interest in learning, improve work confidence and training satisfaction, with statistical significance ( P<0.05). Conclusion:The combination of constructivism teaching theory and PBL teaching mode is beneficial to the training of newly recruited nurses in the department of gastroenterology to independently construct a theoretical framework of knowledge, improve comprehensive ability, and make a useful exploration for the training of newly recruited nurses.

Objective:To study the predictors of postpartum hepatitis in pregnant women with chronic HBV infection.Methods:In this retrospective study, liver function and hepatitis B virology tests of pregnant women with chronic HBV infection at delivery and within 48 weeks were collected from the clinical medical system after the enrollment of eligible patients. Statistical analysis was performed on the obtained data.Results:A total of 533 pregnant women meeting the criteria were enrolled, and the average age of all patients was 29.5±3.7. A total of 408 pregnant women took antiviral drugs during pregnancy for prevention of mother-to-child transmission; 231 patients developed hepatitis within 1 year after delivery. There were significant differences in alanine transaminase (ALT), aspartate transaminase (AST), HBV DNA during delivery, hepatitis B e antigen (HBeAg) during delivery and baseline HBeAg between patients with and without hepatitis. Multivariate binary logistic regression analysis showed that HBeAg ( OR=0.19, 0.074-0.473; P<0.001), ALT ( OR=1.05, 1.021-1.071; P<0.001), albumin ( OR=0.91, 0.833-0.995; P=0.038), platelet ( OR=0.995, 0.992-0.999; P=0.01), neutrophils ( OR=0.98, 0.973-0.995; P=0.004) had significant difference. Conclusions:Baseline HBeAg and ALT are powerful predictors of postpartum hepatitis in pregnant women with chronic HBV infection.

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 auditory outcomes and prognostic factors in ossiculoplasty using autogenous ossicles. METHODS A retrospective review was performed in 126 patients with cholesteatoma or chronic otitis media, who admitted to the Department of Otolaryngology in Jingzhou hospital affiliated to Tongji medical college from January 2014 to July 2016, and underwent canal wall-down tympanoplasty (CWDT) with ossiculoplasty using autogenous ossicles in a single stage. The postoperative complication and hearing thresholds were analyzed after 12 months' follow-up. RESULTS The rate of dry ear was 96.5％. We had not found any extrusion of prosthesis. There was no one with postoperative retraction pocket or recurrence of cholestatoma during the follow-up. Auditory outcomes showed air conduction threshold improved from (52.7±7.4)dB to (39.0±9.1)dB after operation, while the air-bone gaps improved from(27.4±6.9)dB to (20.8±6.2)dB. Postoperative outcomes were considered successful, if the postoperative air-bone gap was <20 dB. The successful hearing was achieved in 88 patients (69.8％). Prognostic factors were analyzed using multivariate analysis with logistic regression. And we found the presence of the stapes and the malleus handle was significantly favorable predictive factors. All the patients recovered well without severe complication. CONCLUSION Autogenous ossicles is very valuable in ossiculoplasty. The present stapes and malleus handle are important factors for the auditory outcomes in ossiculoplasty.
