Objective To analyze the status of persistent human papillomavirus (HPV) infection and the distribution of viral subtypes in the Zhengzhou region. Methods Clinical data of 55239 patients who underwent HPV-DNA genotyping tests from 2018 to 2024 were collected. On the basis of HPV follow-up results, patients were divided into three groups: 849 cases of infection with the same HPV type, 255 cases of persistent infection with different HPV types, and 857 cases of transient HPV infection. Results Among the 9232 initially-screened patients who were positive with HPV, the high-risk HPV (HR-HPV) positive rate was 84.6% (7813/9232), and predominant subtypes were HPV-16 (20.8%), HPV-52 (17.2%), and HPV-53 (9.6%). The low-risk HPV (LR-HPV) positive rate was 15.4% (1419/9232), mainly HPV-81 (28.1%) and HPV-42 (27.0%). Among the 1961 follow-up cases, the rates of persistent and non-persistent infections with the same HPV type were 35.7% (701/1961) and 7.5% (148/1961), respectively. The rates of persistent and non-persistent infections with different HPV types were 10.9% (214/1961) and 2.1% (41/1961), respectively. Meanwhile, 43.7% (857/1961) tested negative upon follow-up. Among the 701 cases of persistent infection with the same HPV type, HR-HPV accounted for 85.7% (601/701), and LR-HPV accounted for 14.3% (100/701). Among the 214 cases of persistent infection with different HPV types, 89.7% (192/214) were high-risk transitions, and 10.3% (22/214) were low-risk transitions. Regardless of HPV types, HR-HPV was more likely to cause persistent infection than LR-HPV. In addition, over 60% of HR-HPV persistent infections resolved within 18 months, 30% developed into persistent infections, and only 15% of patients had persistent infections that last more than 24 months. Conclusion Persistent HPV infections are predominantly high-risk types. Most patients clear the infection within 18 months, approximately 30% develop persistent infections, and about 15% of patients have persistent infections that last more than 24 months. However, the HR-HPV persistent infection rates across different age groups slightly differ.

Objective To compare the effects of ginsenosides Rg1 and Rb1 on depression-and anxiety-like behaviors in chronic unpredictable stress-induced rats.Methods Seventy male SPF grade SD rats were tested for sugar and water preference after 5 days of adaptation and divided into seven groups according to their preference index:a control group,model group,fluoxetine hydrochloride group,ginsenoside Rg1 24 mg/kg group,ginsenoside Rg1 48 mg/kg group,ginsenoside Rb1 33 mg/kg group,and ginsenoside Rb1 67 mg/kg group.All rats,except for the control group,were subjected randomly to one or two different stimulating factors every day for a total of 35 days.On the 36th day,behavioral experiments including sugar and water preference,open field,novel environment feeding inhibition,elevated cross maze,and forced swimming experiments were conducted to investigate the anti-depression and anti-anxiety effects of the treatments.Serum and hippocampal levels of interleukin(IL)-1β,IL-6,tumor necrosis factor(TNF)-α and serum corticosterone were measured by enzyme-linked immunosorbent assay.Results Compared with the model group,ginsenoside Rg1 and Rb1 significantly increased sucrose consumption in the sucrose preference test and decreased immobility in the forced swimming test.Ginsenoside Rg1(48 mg/kg)significantly reduced the latency to eat in the novelty-suppressed feeding test,and ginsenoside Rg1(24 and 48 mg/kg)significantly increased the percentage of open arm entries and time in the elevated cross maze test.Serum corticosterone levels were significantly decreased in the ginsenoside Rg1 and Rb1 groups,serum IL-1β and IL-6 levels were significantly decreased in the ginsenoside Rg1(48 mg/kg)group,serum TNF-α and IL-6 levels were significantly decreased in the ginsenoside Rb1(33 mg/kg)group,and IL-1β,IL-6,and TNF-α levels in the hippocampus were significantly decreased in the ginsenoside Rg1(48 mg/kg)and Rb1(67 mg/kg)groups.Conclusions Both ginsenosides can regulate the hypothalamic-pituitary-adrenal axis and inhibit neuroinflammation,improving depression-and anxiety-like behaviors in rats induced by chronic unpredictable stress.Ginsenoside Rg1 has a significantly better anti-anxiety effect than Rb1.

Transcatheter aortic valve replacement(TAVR)is one of the most important guideline-recommended procedures for severe symptomatic aortic stenosis.Acute cerebral infarction is a serious complication after TAVR,with a high incidence rate and may significantly affect patient prognosis and quality of life.Thrombolysis and mechanical thrombectomy are standard treatments for acute cerebral infarction recommended by guidelines,but evidence of their efficacy and safety in patients undergoing TAVR is limited.We report a patient with acute cerebral infarction after TAVR,who were treated with emergency cerebral angiography and successful transcatheter thrombectomy.

To summarize the nursing experience of a patient with cardiac resynchronization therapy defibrillator(CRT-D)implantation who was about to deplete battery due to repeated discharge after implantation and underwent left ventricular assist device implantation combined with cryoablation.Key points of care were as follows.To begin with,we actively managed arrhythmias and electric storm.Secondly,we carried refined capacity management to avoid water and sodium retention.Thirdly,we formulated personalized anticoagulation programs to reduce the risk of bleeding and thrombosis.Then,the pump line infection should be prevented as early as possible.At the whole stage,we provided psychological counseling to improve emotional state.After discharge,regular follow-up was carried out through online and offline method to ensure quality of life in the long term.After careful treatment and nursing care,23 days after surgery,the patient was discharged smoothly,and good follow-up after discharge.

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.

OBJECTIVE To investigate the effect and mechanism of Panax notoginseng saponins （PNS） on wound healing after anal fistula surgery in rats by regulating the hypoxia-inducible factor-1α （HIF-1α）/vascular endothelial growth factor （VEGF）/ vascular endothelial growth factor receptor-2 （VEGFR2） signaling pathway. METHODS SD rats were selected to establish a postoperative rat model of anal fistula by infecting wound with Escherichia coli. The model rats were randomly grouped into model group， PNS low-dose and high-dose groups （15， 30 mg/cm2）， high-dose of PNS+2-methoxyestradiol （2ME2） group （PNS 30 mg/cm2+HIF-1α inhibitor 2ME2 4 mg/kg）， with 10 rats in each group. Another 10 normal rats were selected for back hair removal treatment as the control group. Each drug group was injected with the corresponding drug solution intramuscularly or （and） intraperitoneally， once a day， for 3 weeks. After the last administration， the wound healing rate （excluding the control group）， microvascular density （MVD）， the expression of collagen Ⅰ and fibronectin （FN） in the wound tissue were detected in each group； the levels of angiogenic factors [VEGF， E-mail：842710813@qq.com angiopoietin-Ⅰ （Ang-Ⅰ）， Ang-Ⅱ] in serum， the levels of inflammatory factors [interleukin-6 （IL-6） and IL-2] in serum binggui7183@163.com and wound tissue as well as the expressions of the related proteins of HIF-1α/VEGF/VEGFR2 signaling pathway in the wound tissue of rats were also detected in each group. RESULTS The MVD， the expression of collagen Ⅰ and FN in the wound tissue， and the levels of IL-6 and IL-2 in serum and wound tissue of rats increased significantly in the model group， compared to the control group （P＜0.05）， while the serum levels of VEGF， Ang- Ⅰ and Ang-Ⅱ decreased significantly （P＜0.05）. The wound healing rate， the MVD in wound tissue， the serum levels of VEGF， Ang-Ⅰ and Ang-Ⅱ， the expressions of collagen Ⅰ and FN in the wound tissue， and protein expressions of HIF-1α， VEGF and VEGFR2 in the PNS low-dose and high-dose groups increased significantly， compared to the model group （P＜0.05）， while the levels of IL-6 and IL-2 in serum and wound tissue decreased significantly （P＜0.05）； the high-dose PNS had a stronger effect （P＜ 0.05）. 2ME2 could weaken the effect of PNS on above indicators of rats after anal fistula surgery （P＜0.05）. CONCLUSIONS PNS can promote the production of angiogenic factors and inhibit the production of pro-inflammatory factors， thereby promoting wound healing in rats after anal fistula surgery. The above effects are related to the activation of HIF-1α/VEGF/VEGFR2 signaling pathway.

Objective:To identify the risk factors for prolonged length of stay in post-anesthesia care unit (PACU-LOS) and development of a prediction model in the patients undergoing radical esophagectomy.Methods:The medical records from patients of both sexes, aged 40-80 yr, of American Society of Anesthesiologists Physical Status classificationⅠ-Ⅲ, transferred to PACU with tracheal intubation after radical esophagectomy under general anesthesia in our hospital from January 2019 to December 2020, were retrospectively collected. The patient′s age, gender, American Society of Anesthesiologists Physical Status classification, smoking history, drinking history, history of non-thoracic surgery, history of hypertension, history of diabetes mellitus, preoperative anemia, respiratory diseases, doses of anesthetics, preoperative nerve block, intraoperative consumption of opioids and dexmedetomidine, operation method (thoracotomy and endoscopic surgery), operation time, usage of vascular drugs, bradycardia, hypotension, red blood cell infusion, plasma infusion, total infusion volume, blood loss and urine volume were collected. The extubation time in PACU, visual analog scale scores at rest at 10 min after extubation, consumption of rescue analgesics in PACU, hypoxemia after extubation, and occurrence of nausea and vomiting were also collected. Patients were divided into PACU-LOS normal group (PACU-LOS≤2 h) and PACU-LOS prolonged group (PACU-LOS>2 h) according to the PACU-LOS. Logistic regression analysis was used to identity the risk factors for prolonged PACU-LOS in the patients undergoing radical esophagectomy, and the predictive model was established and verified. The receiver operating characteristic curves were used to evaluate the model discrimination and Hosmer-Lemshow goodness-of-fit test was used to evaluate the consistency of the model.Results:A total of 943 patients were included in this study, and the incidence of prolonged PACU-LOS was 15.7%. The results of logistic regression analysis showed that chronic obstructive pulmonary disease ( OR=4.900, 95% confidence interval [ CI] 2.512-9.556), increasing age ( OR=22.154, 95% CI 6.736-73.003), prolonged time of extubation ( OR=1.214, 95% CI 1.174-1.256) and hypoxemia after extubation ( OR=4.891, 95% CI 2.167-11.039) were risk factors for prolonged PACU-LOS, and the preoperative use of nerve block ( OR=0.358, 95% CI 0.190-0.672) was a protective factor for prolonged PACU-LOS in the patients undergoing radical esophagectomy ( P<0.05). The area under the receiver operating characteristic curve (95% CI) was 0.947 (0.925-0.963), the sensitivity was 0.878, and the specificity was 0.906. The internal validation of the prediction model was carried out using the receiver operating characteristic curve in the validation set, and the area under the curve (95% CI) was 0.942 (0.895-0.942, P<0.001) and the Youden index was 0.784. The line chart prediction model was developed. The prediction analysis model was verified by Hosmer-Lemshow test, P<0.001, and the C-index visualized line chart prediction model was 0.946. Conclusions:Preoperative chronic obstructive pulmonary disease, increasing age, prolonged time of extubation and hypoxemia after extubation are risk factors for prolonged PACU-LOS, and preoperative use of nerve block is a protective factor for prolonged PACU-LOS. The risk prediction model developed can effectively predict the occurrence of prolonged PACU-LOS in the patients undergoing radical esophagectomy.

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.

Perimenopausal syndrome （MPS）， a common endocrine system disease， is one of the diseases responding specifically to traditional Chinese medicine （TCM）. The China Association of Chinese Medicine organized experts in endocrinology， gynecology， and interdisciplinary fields of both Western and Chinese medicine to discuss the advantages and challenges of diagnosing and treating MPS with Western medicine， TCM， and integrative medicine. Experts at the conference believe that MPS is initiated by estrogen decline and rooted in deficiency， with the pathogenesis being imbalance between Yin and Yang in the kidney. The hormone replacement therapy in Western medicine for menopause can rapidly alleviate related symptoms by quickly restoring the estrogen level and timely detect and delay complications of menopause， whereas such a therapy has certain risks， necessitating close monitoring of adverse reactions. Moreover， the various contraindications and precautions limit the clinical application of the hormone replacement therapy. TCM has advantages in synergistically alleviating symptoms such as hot flashes， sweating， sleep disorders， and emotional abnormalities of MPS without causing obvious adverse reactions. However， its efficacy is slower than the hormone replacement therapy， and the TCM evidence for preventing and treating complications of menopause remains unclear. Three suggestions were proposed for the future development of both Western and TCM for ameliorating MPS. First， an integrated diagnosis and treatment system for MPS with both Western and Chinese medicine should be established. Second， high-quality evidence-based interventions for MPS should be developed with TCM alone or in combination with Western medicine. Third， efforts should be made to promote the new TCM drug development and the interdisciplinary cooperation for treating MPS.
