Objective To explore the application effect of family-community-hospital linked care in patients with chronic hepatitis B. Methods A total of 118 patients with chronic hepatitis B were selected and randomly divided into control group and observation group using a random number table method, with 59 patients in each group. The control group received routine health education, while the observation group received family-community-hospital ternary linked care on the basis of the control group received family-community-hospital linked care. The social support, treatment adherence, quality of life, and fear of disease progression between the two groups were compared before intervention and 2 months after the intervention. Results Two months after the intervention, the scores of the Social Support Rating Scale (SSRS), the Treatment Adherence Scale for chronic hepatitis B patients, and the Chronic Liver Disease Questionnaire (CLDQ) increased in both groups compared with those before the intervention, and the above scores were higher in the observation group than in those in the control group (P < 0.05). The scores of social family and physical health on the Fear of Progression Questionnaire-Short Form (FoP-Q-SF) decreased in both groups compared with those before the intervention, and the scores were lower in the observation group than those in the control group (P < 0.05). Conclusion Family-community-hospital linked care can improve social support, treatment adherence, and quality of life in patients with chronic hepatitis B and alleviate their fear of the disease.

Objective To investigate etiologic characteristics of hand, foot, and mouth disease (HFMD) in a sentinel hospital in Guangzhou from 2017 to 2021, and to provide a scientific basis for the prevention and control of HFMD. Methods Descriptive epidemiologic methods were used to analyze the etiologic characteristics of mild cases of HMFD during 2017-2021. Results A total of 1 633 specimens of mild cases of HMFD were collected from 2017 to 2021. The total enterovirus (EV) positive rate was 78.41%, among which the positive rates of the main pathogen Cox A6, Cox A16, Cox A10, and EV71 were 40.83%, 17.68%, 6.13%, and 1.62%, respectively. The total positive rate of enteroviruses and the positive rate of enteroviruses of all types in each year were statistically different (P<0.001). In 2017-2021, the prevalence of HFMD in Guangzhou was mainly Cox A6, followed by Cox A16 which had the highest positive rate in 2018 (24.62%). The positive rate of EV71 decreased year by year. Cox A6 was highly prevalent from June to December every year, while the detection rate of Cox A16 was high from April to August every year. The positive detection rate of EV71 was high from January to May in 2017 and low from 2018 to 2021, with no epidemic peak. Conclusion From 2017 to 2021, the main pathogen of HMFD in Guangzhou is Cox A6, not EV71 or CoxA16, which suggests that it is of great significance to strengthen the monitoring of epidemic trend of HFMD for the prevention and control of HFMD.

Objective:To investigate the efficacy and safety of SIMPLE regimen in the treatment of extranodal NK/T-cell lymphoma (ENKTCL).Methods:The clinical data of 11 patients with ENKTCL who were admitted to the University of Hong Kong-Shenzhen Hospital from January 2012 to January 2022 were retrospectively analyzed. The patients received 4-6 courses of SIMPLE (cisplatin, gemcitabine, ifosfamide, etoposide, dexamethasone, and pegasparaginase) regimen chemotherapy, and stage Ⅰ and Ⅱ patients who also received local radiotherapy after 2 or 3 courses of chemotherapy. Patients were evaluated for mid-treatment and end-of-treatment outcomes, and the adverse effects of patients were evaluated in each treatment cycle. The Kaplan-Meier method was used to analyze the progression-free survival (PFS) and overall survival (OS) of the 11 patients.Results:All 11 patients were nasal type, with the median age of 41 years old (26-67 years old), including 5 males and 6 females, 3 relapsed cases and 8 newly treated cases. Of the 10 patients evaluated for efficacy, 9 achieved complete remission and 1 achieved at least partial remission (efficacy was assessed based on follow-up). All 11 patients were followed up for a median time of 50 months (15-72 months) and 2 relapsed patients died due to disease progression. The expected 5-year PFS rate and OS rate of 11 patients were both 90.0%, and the expected 5-year OS rate was 100.0% and 66.6% in newly treated and relapsed patients, respectively. Common adverse effects were hematologic adverse reactions, infections, gastrointestinal symptoms, elevated transaminases, and hypofibrinogenemia, all of which were curable. There is no treatment-related death.Conclusions:The SIMPLE regimen for the treatment of ENKTCL has a high remission rate, the patients have long survival time, and the regimen is moderately well tolerated.

Objective:To investigate the current sedation level of patients with mechanical ventilation in ICU, and to explore the influence of early different sedation levels on clinical outcomes, so as to provide theoretical basis for better guidance of clinical sedation evaluation and implementation of sedation strategy management.Methods:This study was a retrospective longitudinal study. The 201 patients with invasive mechanical ventilation who underwent sedation in the Department of Intensive Care Medicine of the First Affiliated Hospital of Guangxi Medical University from January to December 2021 were selected by convenience sampling method. According to the results of Richmond Agitation-Sedation Scale(RASS), the patients were divided into deep sedation group (98 cases) and shallow sedation group (103 cases). The influencing factors of endotracheal intubation retention time and outcome were investigated by Cox multifactor analysis.Results:In the early sedation ≤48 h after the start of mechanical ventilation, 63.2%(2 143/3 389) of patients with invasive mechanical ventilation had a RASS score of shallow sedation, 35.2%(1 194/3 389) of patients with deep sedation, and 1.5%(52/3 389) of patients with insufficient sedation. Cox multivariate regression analysis showed that age, sedation level, duration of invasive mechanical ventilation and continuous renal replacement therapy were the factors influencing the indentation time of tracheal insertion ( χ2 values were 4.73 to 74.31, all P<0.05); early deep sedation was a risk factor for delayed extubation ( HR=0.499, 95% CI 0.276-0.903, P<0.05); gender, sedation level, invasive mechanical ventilation duration, acute physiology and chronic health evaluation Ⅱ scores, admission mode, continuous renal replacement therapywere the influencing factors of patient outcomes ( χ2 values were 4.41 to 26.20, all P<0.05). The deeper the sedation, the worse the patient outcomes ( HR=0.568, 95% CI 0.335-0.963 all P<0.05) . Conclusions:The early sedation level is related to the retention time and outcome of tracheal intubation in ICU patients with mechanical ventilation, and different sedation levels affect the clinical outcome of patients. The retention time of tracheal intubation in patients with shallow sedation was shortened, which was beneficial to the outcome of patients.Therefore, sedation evaluation should be strengthened in clinical work, and sedation methods should be selected according to the needs of patients. In the absence of contraindications, the shallow sedation strategy should be implemented as soon as possible. This study provides some reference and theoretical basis for the formulation and management of clinical sedation strategies.

Serine/arginine-rich splicing factor 7 (SRSF7), a known splicing factor, has been revealed to play oncogenic roles in multiple cancers. However, the mechanisms underlying its oncogenic roles have not been well addressed. Here, based on N⁶-methyladenosine (m⁶A) co-methylation network analysis across diverse cell lines, we find that the gene expression of SRSF7 is positively correlated with glioblastoma (GBM) cell-specific m⁶A methylation. We then indicate that SRSF7 is a novel m⁶A regulator, which specifically facilitates the m⁶A methylation near its binding sites on the mRNAs involved in cell proliferation and migration, through recruiting the methyltransferase complex. Moreover, SRSF7 promotes the proliferation and migration of GBM cells largely dependent on the presence of the m⁶A methyltransferase. The two m⁶A sites on the mRNA for PDZ-binding kinase (PBK) are regulated by SRSF7 and partially mediate the effects of SRSF7 in GBM cells through recognition by insulin-like growth factor 2 mRNA-binding protein 2 (IGF2BP2). Together, our discovery reveals a novel role of SRSF7 in regulating m⁶A and validates the presence and functional importance of temporal- and spatial-specific regulation of m⁶A mediated by RNA-binding proteins (RBPs).

Objective:To observe the effects of static 70° head-up tilted standing and of repeated body repositioning on hemodynamics in healthy young and middle-aged persons.Methods:The hemodynamics of 24 middle-aged and 23 younger persons were studied. Both groups were requested to perform static 70° head-up tilted standing and to repeatedly change their body position from 0° to 70° of tilt at a velocity of 1°/second for ten minutes in a random order. Before, between and after each test the subjects rested supine for ten minutes. Hemodynamic variables and blood pressure were recorded non-invasively.Results:The average heart rate (HR) increased significantly in both groups when rising from supine to the testing positions. In 70° tilted standing the average HR of the youth group, 84.0±9.5bpm, was significantly higher than that in the other position and that of the middle-aged group in the same position. The average HR of the middle-aged group in 70° tilted standing was also significantly higher than in the other position. Among the middle-aged group, the average stroke volume (SV) in the testing positions was significantly lower than when resting. Significant differences were observed in the average diastolic blood pressure (DBP) between the testing and rest positions for both groups, with the average DBP of the middle-aged group significantly higher than that of the youth group in all three positions. Among the youth group, the average SV, CO and systolic blood pressure (SBP) of the males were significantly higher than among the females in all of the different body positions.Conclusions:Young persons mainly rely on an increased heart rate to maintain cardiac output while middle-aged participants appear to achieve this through increased peripheral resistance. Repeated position changes have less impact on hemodynamics than 70° inclined standing, making it a safer and more stable training method. However, the long-term effects of such intervention need to be confirmed in further studies.

Clitoris lesion is most readily classified into hormone-dependent and hormone-independent cause. It can also be characterized as congenital or acquired nature. Clitoromegaly is the most common presentation of clitoral lesions clinically. Hormone-dependent clitoromegaly is mainly attibuted to the increase of androgen, while the most comomon cause of hormone-independent clitoromegaly is neurofibromatosis. Except that, there are so many other disorders which can cause clitoromegaly, leading to the difficulty for diagnosis. However, the literature concerning the management of clitoromegaly is scarce.The present study summarized the lesions of clitoromegaly from the etiology, diagnosis, and differential diagnosis to treatment. This may help clinicians to make a reasonbale management when facing this kind of disease.

Objective: To evaluate the effects of the intervention based on WeChat on blood pressure control in patients with essential hypertension. Methods: The databases of CNKI，Wanfang，VIP，PubMed and the Cochrane Library were researched for the literatures about effects of the intervention based on WeChat on blood pressure control in patients with essential hypertension published from 2011 to 2018. These papers were retrieved and evaluated according to inclusion and exclusion criteria. Stata 12.0 software was used for meta analysis. Results: Eleven out of 880 papers were included into meta analysis. There were 1 174 cases，with 587 cases in the experimental group and 587 cases in the control group. The results of the meta analysis showed that compared with traditional health intervention method，the intervention based on WeChat significantly reduced the level of systolic blood pressure（WMD=14.77，95%CI：11.76-17.77）and diastolic blood pressure（WMD=8.17，95%CI：5.67-10.67）of hypertensive patients. Subgroup analysis showed that the longer the intervention，the better the effects（P<0.05）. Conclusion The intervention based on WeChat is more helpful than traditional health intervention for blood pressure control of patients with essential hypertension.
