Objective To explore the influencing factors for visual field defects in patients with advanced glaucoma.Methods Two hundred and six patients(206 eyes)with advanced glaucoma treated in the First Affiliated Hospital of Xinxiang Medical University from January 2019 to January 2023 were selected as the research subjects.The clinical and follow-up data of the patients were retrospectively analyzed.The patients were divided into the temporal visual island group(n=134)and the tubular visual field group(n=72)based on the degree of visual field defects.The risk factors for visual field defects in patients with advanced glaucoma were analyzed through univariate and multivariate logistic regression.Results The univariate logistic regression analysis showed that comorbidity with high myopia,types of glaucoma,peak and mean intraocular pressure during follow-up,types of drugs,and types of cumulative medication use were associated with visual field defects in patients with advanced glaucoma(P＜0.05).The multivariate logistic regression analysis showed that comorbidity with high myopia,chronic primary angle closure glaucoma(CPACG),and peak intraocular pressure ≥21 mm Hg(1 mm Hg=0.133 kPa)during follow-up were the independent risk factors for visual field defects in patients with advanced glaucoma(P＜0.05).Conclusion The incidence of temporal visual island is high in patients with advanced glaucoma.It is necessary to strengthen intraocular pressure monitoring and related eye health education in patients with high myopia,CPACG,and peak intraocular pressure≥21 mm Hg during follow-up to improve the visual field defects.

BACKGROUND:Traumatic patellar dislocation with medial patellofemoral ligament tearing at femoral attachment or body is usually performed by medial patellofemoral ligament reconstruction surgery.To promote tendon bone healing after medial patellofemoral ligament reconstruction,the researchers used a variety of biological treatment technologies including growth factors,stem cells and platelet-rich plasma. OBJECTIVE:To investigate the clinical effect of medial patellofemoral ligament reconstruction by leukocyte-and platelet-rich fibrin with autologous hamstring tendon for traumatic patellar dislocation. METHODS:Thirty-seven patients with traumatic patellar dislocation in First Hospital of Qinhuangdao from February 2019 to February 2021 were randomly divided into a trial group(n=18)and a control group(n=19).The trial group received medial patellofemoral ligament reconstruction by leukocyte-and platelet-rich fibrin with an autologous hamstring tendon.The control group received medial patellofemoral ligament reconstruction by a simple autologous hamstring tendon.Patients in the two groups were followed up for 12 months.Knee pain and functional status were evaluated by visual analog scale score,Lysholm score,Kujala patellofemoral joint score and knee range of motion.The patellar tilt angle,patellar congruence angle and patellar lateral shift rate of the patellofemoral joint were measured by MRI and CT films to evaluate the stability and improvement of the patellofemoral joint. RESULTS AND CONCLUSION:(1)The visual analog scale scores of the two groups at 6 and 12 months after operation were lower than those before operation(P<0.05).The Lysholm score and Kujala patellofemoral joint score at 6 and 12 months after operation were higher than those before operation(P<0.05).The Lysholm score and Kujala patellofemoral joint score in the trial group were higher than those in the control group 6 months after operation(P<0.05).There was no significant difference between the two groups in the visual analog scale score,Lysholm score and Kujala patellofemoral joint score 12 months after operation(P>0.05).(2)The patellar tilt angle,patellar congruence angle,patellar lateral shift rate and range of motion of the patellofemoral joint were significantly improved in both groups 12 months after operation(P<0.05).The patellar tilt angle was smaller in the trial group than that in the control group 12 months after operation(P<0.05).Patellar congruence angle,patellar lateral shift rate,range of motion and MRI score were not statistically significant between the two groups 12 months after operation(P>0.05).(3)These results confirm that medial patellofemoral ligament reconstruction by leukocyte-and platelet-rich fibrin with autologous hamstring tendon can treat traumatic dislocation effectively,improve the function of the knee joint,and restore the movement track of the patella.

Objective:To analyze the epidemiological characteristics and clinical features of pertussis cases reported in Shandong Province of China.Methods:Data on pertussis cases in Shandong Province from 2007 to 2022 were collected from China Information System for Disease Control and Prevention. At the same time, some case information was collected from the database of notifiable pertussis in Shandong Province from 2007 to 2022. The distribution characteristics and clinical features of pertussis were analyzed. A spatial distribution map of pertussis cases in Shandong Province was drawn.Results:A total of 26 122 pertussis cases were reported in Shandong Province during 2007-2022, with an annual incidence rate ranging from 0.11 to 5.77 cases per 100 000 people. Cases occurred throughout the whole year, with a seasonal peak occurring in spring and summer, especially in July and August. In recent years, reported cases were mainly distributed in the central and western regions of Shandong Province, with fewer cases in the eastern region. The hot spots of the disease shifted from Heze and Dezhou City in 2007-2013 to Jinan and Tai′an city in 2014-2022. The age range of onset was from 1 day to 93 years old. The proportion of cases with age≤1 year was the largest (41.81%, 10 922/26 122), and the proportion of cases aged 0-6 months decreased from 32.21% (67/208)-55.67% (157/282) within the period of 2007 to 2013 to 16.78% (883/5 263)-41.97% (444/1 058) within the period of 2014 to 2022, with a statistically significant trend ( χ2 trend=670.01, P<0.001). There were 13 682 male cases and 12 440 female cases, with a male-female ratio of 1.10∶1. The male-female ratio was 1.45∶1 (806∶556) from 2007 to 2013 and 1.08∶1 (12 876∶11 884) from 2014 to 2022. The proportion of women increased from 42.31% (88/208) in 2007 to 47.84% (2 518/5 263) in 2022, and with a significant trend ( χ2 trend=22.25, P<0.001). In pertussis cases, the proportions of scattered children, kindergarten children and students were 71.38% (18 645/26 122), 15.13% (3 951/26 122), and 11.60% (3 031/26 122), respectively. The top five clinical symptoms of pertussis cases were paroxysmal spasmodic cough (86.33%, 21 411 cases), flushing (39.61%, 9 824 cases), restless sleep (34.51%, 8 558 cases), fever (30.80%, 7 638 cases), and crowing (27.53%, 6 829 cases). Among 24 802 cases, there were 15 542 cases (62.66%) with a history of immunization against pertussis vaccine. Conclusion:From 2007 to 2022, the incidence rate of pertussis cases in Shandong Province shows an upward trend, with the majority being young children, and the clinical symptoms are relatively typical.

AIM: To evaluate the changes in corneal epithelial thickness(CET)and corneal optical density(CD)after smart pulse technology(SPT)-assisted transepithelial photorefractive keratectomy(TPRK)and analyze their correlation.METHODS: The prospective study included 60 patients(120 eyes)with myopia and myopic astigmatism who underwent SPT-TPRK in the ophthalmology department at the First Affiliated Hospital of Xinxiang Medical University between February and August 2023. Changes in CET and CD were evaluated preoperatively and at 1 wk, 1 and 3 mo postoperatively.RESULTS: A total of 14 cases(28 eyes)were lost to follow-up, and 3 patients(6 eyes)with postoperative haze were excluded from this study, resulting in a final inclusion of 43 patients(86 eyes). At 1 wk after SPT-TPRK, CET had statistically significantly thickened compared to preoperative levels(P<0.05), particularly in the CET at 0-2 mm central corneal area(P<0.05). At 1 mo after SPT-TPRK, the CET at 0-2 mm area had statistically significantly decreased(P<0.05). At 3 mo after SPT-TPRK, the CET at 0-2 mm had essentially reached preoperative levels. Postoperative CD values increased, with a positive correlation between CET in the 0-2 mm area and CD in the whole 0-2 mm area(r=0.256, P<0.05), and a positive correlation between CET in the 2-5 mm area and CD in the anterior 2-6 mm area(r=0.319, P<0.05).CONCLUSION: Corneal epithelial remodeling takes 3 mo in areas within 2 mm of the central cornea; areas with thinner CET have faster postoperative corneal epithelial remodeling and greater thickening in the early postoperative period; CD increases in the early postoperative period compared to the preoperative value, and in some areas, there is a positive correlation between CET and CD value.

Osteoporotic thoracolumbar fracture in the elderly will seriously reduce their quality of life and life expectancy. For osteoporotic thoracolumbar fracture in the elderly, spinal reconstruction is necessary, which should comprehensively consider factors such as the physical condition, fracture type, clinical characteristics and osteoporosis degree. While there lacks relevant clinical norms or guidelines on selection of spinal reconstruction strategies. In order to standardize the concept of spinal reconstruction for osteoporotic thoracolumbar fracture in the elderly, based on the principles of scientificity, practicality and progressiveness, the authors formulated the Clinical guideline for spinal reconstruction of osteoporotic thoracolumbar fracture in elderly patients ( version 2022), in which suggestions based on evidence of evidence-based medicine were put forward upon 10 important issues related to the fracture classification, non-operative treatment strategies and surgical treatment strategies in spinal reconstruction after osteoporosis thoracolumbar fracture in the elderly, hoping to provide a reference for clinical treatment.

Objective:To explore the role and molecular mechanism of DNAJB6 in liver regeneration during partial liver transplantation(PLT).Methods:Dark agouti(DA, donor)and Lewis(recipient)rats were prepared for liver regeneration model of PLT.Rats were divided into before perfusion, after split liver perfusion, after portal vein opening, before abdominal closure and Day 3/7 after surgery groups(n=6 each)for timepoints of PLT.C57 mice were performed for residual liver regeneration model of partial hepatectomy and divided into control, Day 1/2/3/4/5 groups(n=6 each)for timepoints of hepatectomy.Gene Expression Omnibus liver regeneration data were utilized for locating DNAJB6 in liver regeneration.DNAJB6 low-expression human hepatocytes were constructed by DNAJB6-Si transfection.The relationship between DNAJB6 and liver regeneration was examined by Western blot detection of cell proliferation markers PCNA and CCK8 cell proliferation experiments.And the possible molecular mechanism of DNAJB6 regulating liver regeneration in PLT was studied by Western blot detection of nuclear protein and protein in cell proliferation signal pathway.Results:The result of residual liver regeneration of partial hepatectomy showed that DNAJ family genes were differentially expressed on regenerated liver gene chip and DNAJB6 was lowly expressed on regenerated liver gene chip.Meanwhile, DNAJB6 was lowly expressed in regenerated liver tissues of PLT and partial liver resection.After silencing DNAJB6 by transfecting DNAJB6-Si, the cellular expression level of PCNA and proliferation rate increased.However, nuclear extraction failed to detect the nuclear/plasma changes of β-catenin and the level of Wnt4 protein had no obvious change.Although the activation levels of p38 and JNK2 downstream of Ras/MAPK showed no change, there was a higher activation level of ERK.Conclusions:In regenerating liver tissue, hepatocytes may suppress the Ras/MEK/ERK signaling pathway by lowering the expression level of DNAJB6 to promote liver regeneration.

Aortic stenosis (AS) is the most common primary valve lesion requiring surgery or transcatheter intervention in modern era. Its prevalence is rising rapidly as a consequence of the aging population. Transcatheter aortic valve replacement (TAVR) as a therapy option for older high-risk symptomatic severe AS patients has emerged and is currently extending its indications towards surgery intermediate- and low-risk subjects. Considering the common characteristics of frailty and high comorbidity among AS patients, cardiac rehabilitation (CR) has been proven to improve not only survival but also quality of life in previous reports. CR as a classⅠ recommendation in guidelines for the prevention and treatment of cardiovascular disease has been widely used in clinical practice. The purpose of this article is to sort out the current CR programs for TAVR patients in global medical management, and explore the CR optimization program fit for China medical model in post COVID-19 pandemic era.

Objective:To evaluate partial ventral hepatectomy in the treatment of patients with complicated iatrogenic high bile duct injury.Methods:The clinical data of 8 cases of complicated iatrogenic high bile duct injury treated with the assistance of hepatic ventral segmentectomy from Mar 2013 to May 2020 at Hunan Provincial People's Hospital was retrospectively analyzed.Results:Among the 8 patients, 5 patients underwent partial Ⅳb lobectomy, and 3 patients received partial Ⅳb and Ⅴ segmentectomy of the liver. All the operation was successful without death in hospital. One case developed subphrenic infection and seroperitoneum, which was healed by anti-infection treatment and abdominocentesis. The postoperative follow-up time was 5-90 months, and all of patients are doing well. There was no stenosis in intrahepatic bile duct by postoperative cholangiography or MRI.Conclusions:Quadrate lobe hepatectomy provides a wide view for the treatment of complicated iatrogenic high bile duct injury by fully opening the first porta hepatis and exposing the primary and secondary bile duct branch helping establish a wide patent tension free bile duct-jejunostomy.

Objective: To evaluate the efficacy and safety of ombitasvir/paritaprevir/ritonavir (OBV/PTV/r) 25/150/100 mg once daily and dasabuvir (DSV) 250 mg twice daily combined with ribavirin in adult patients of Mainland China with chronic HCV genotype 1b infection and compensated cirrhosis. Methods: An open-label, multicenter, phase 3 clinical trial study was conducted in mainland China, Taiwan, and South Korea. Adult patients with compensated cirrhosis (Metavir score =F4) who were newly diagnosed and treated for hepatitis C virus genotype 1b infection with ombitasvir/paritaprevir/ritonavir and dasabuvir combined with ribavirin for 12 weeks were included. Assessed SVR rate of patients obtained at 12 and 24 weeks after drug withdrawal. Efficacy and safety were evaluated in patients who received at least one time study drugs. Results: A total of 63 patients from mainland China were enrolled, 62 of whom (98.4%) had a baseline Child-Pugh score of 5 points. The overall rate of SVR12 and SVR24 in patients was 100% (95% CI: 94.3% to 100.0%). Most of the adverse events that occurred were mild. The incidence of common (≥10%) adverse events and laboratory abnormalities included elevated total bilirubin (36.5%), weakness (19.0%), elevated unconjugated bilirubin (19.0%) and conjugated bilirubin (17.5%), and anemia (14.3%). Three cases (4.8%) of patients experienced Grade ≥ 3 adverse events that were considered by the investigators to be unrelated to the study drug. None patients had adverse events leading to premature drug withdrawal. Conclusion Mainland Chinese patients with chronic HCV genotype 1b infection and compensated cirrhosis who were treated with OBV/PTV/r plus DSV combined with RBV for 12 weeks achieved 100 % SVR at 12 and 24 weeks after drug withdrawal. Tolerability and safety were good, and majority of adverse events were mild.
