Objective To explore the relationship between blood uric acid levels and non-alcoholic fatty liver disease in patients with type H hypertension.Methods The clinical data of 284 patients with type H hyper-tension admitted to the Cardiovascular Department,Xianyang Hospital,Yan'an University in 2022 were collected and retrospectively reviewed.The patients were divided into NAFLD group(n=88)and normal group(n=196)according to whether they had NAFLD.The general information and laboratory indicators were compared between the two groups.Multivariate logistic regression analysis was conducted to explore the influencing factors of NAFLD in H-type hypertension patients.The draw ROC curves were plotted to observe the role of SUA in predicting NAFLD and select the optimal cutoff value based on the maximum Youden index.Results The NAFLD group demonstrated higher levels in body mass index,systolic blood pressure,diastolic blood pressure,total cholesterol,triglycerides,low-density lipoprotein cholesterol,SUA,γ-Glutamyl transpeptidase and alanine aminotransferase compared to the normal group,but significantly lower levels at age and high-density lipoprotein cholesterol(P＜0.05).The multivariate logistic regression analysis showed that elevated levels of BMI(OR=1.173,95%CI:1.066～1.291),SUA(OR=1.005,95%CI:1.001～1.010),and TG(OR=1.929,95%CI:1.042～3.574)were risk factors for NAFLD in patients with type H hypertension(P＜0.05).The ROC curves showed that the area under the curve(AUC)of SUA,TG,BMI,and their combination were 0.709,0.707,0.750,and 0.796,respectively.Conclusion type H hypertensive NAFLD patients have high levels of BMI,SUA,TG compared to non-NAFLD patients.Elevated SUA is a risk factor for type H hypertensive NAFLD patients,with SUA＞337 μmol/L as a significant value for predicting NAFLD.

【Objective】 To investigate the prevalence and risk factors of lower urinary tract symptoms (LUTS) in rural children and adolescents. 【Methods】 An epidemiological LUTS survey was carried out on 4 100 children and adolescents (aged 6-16 years) in five primary and secondary schools in rural Henan by means of stratified random cluster sampling using anonymous questionnaires. Daytime urinary incontinence (DUI), nocturnal enuresis (NE), and postnatal diaper use and toilet training were investigated. 【Results】 A total of 3 885 valid questionnaires were recovered (with a recovery rate of 94.76%). The total prevalence of the four symptoms of LUTS, including urgency, frequency, DUI and NE, were 16.42%, 10.91%, 7.41% and 7.95%, respectively. As much as 21.13% subjects had at least one symptom. The prevalence of the four symptoms decreased gradually with age, decreased sharply in those aged 6 to 12 years, and then decreased slowly. The prevalence of LUTS in children who stopped using diapers and stared urine training after 1 year of age was significantly higher than that of those within 1 year of age (χ²=21.605, 23.111, 24.189, 23.509, all P<0.05; χ²=102.17, 72.168, 53.656, 197.76, all P<0.05). There were significant differences in the prevalence of LUTS between those with and without toilet training (χ²=315.273, 198.438, 105.723, 272.502, all P<0.05). The prevalence of LUTS in males was significantly higher than that in females (P<0.05). Constipation, prepuce and phimosis in boys were significantly associated with the prevalence of LUTS (P<0.05). 【Conclusion】 Rural children and adolescents have a high prevalence of LUTS. Diaper use after 1 year of age, history of urinary tract infection (UTI), lack of toilet training, constipation, and abnormal prepuce are risk factors of LUTS. Urine training before 1 year of age is a protective factor of LUTS.

Objective: To investigate the trends in incidence of viral hepatitis in Yuxi City, Yunnan Province from 2004 to 2022, so as to provide insights into the management of viral hepatitis. Methods: Data of viral hepatitis cases in Yuxi City from 2004 to 2022 were retrieved from the China Disease Prevention and Control Information System. The temporal, human and spatial distribution of viral hepatitis cases were analyzed using a descriptive epidemiological method, and the trends in incidence of viral hepatitis were evaluated in Yuxi City from 2004 to 2022 using annual percent change (APC) and average APC (AAPC). Results: A total of 37 430 viral hepatitis cases were reported in Yuxi City from 2004 to 2022, with an average annual incidence rate of 91.27/105, and the incidence showed a tendency towards a rise (AAPC=12.686, P<0.05). There were 29 229 cases with hepatitis B, 5 796 cases with hepatitis C, 1 451 cases with hepatitis A, 520 cases with hepatitis E and 434 cases with unclassified hepatitis reported in Yuxi City, with average annual incidence rates of 71.27/105, 14.13/105, 3.54/105, 1.27/105 and 1.06/105, respectively. The average annual incidence rates of viral hepatitis were 98.24/105 and 78.94/105 among men and women, which both appeared a tendency towards a rise (AAPC=12.415% and 12.581%, both P<0.05). The highest average annual incidence of viral hepatitis was seen among residents at age of 25 to 29 years (139.89/105), with the lowest seen among residents at ages of 0 to 4 years (11.38/105), and the average annual incidence of viral hepatitis appeared a tendency towards a rise with age (P<0.05). The highest average annual incidence of viral hepatitis was seen in Huaning County (234.24/105), with the lowest seen in Chengjiang City (26.11/105), and the average annual incidence appeared a tendency towards a rise in Xinping County from 2004 to 2022 (AAPC=21.451%, P<0.05). Conclusions The reported incidence of viral hepatitis appeared a tendency towards a rise in Yuxi City from 2004 to 2022, with hepatitis B as the main type. High incidence was seen among men and adolescents. The viral hepatitis control strategy requires to be adjusted with adaptations to high-incidence hepatitis subgroups, residents and regions.

Objective:To evaluate the efficacy and tolerability of crisaborole 2% ointment in the treatment of childhood atopic dermatitis (AD) at the early stage, and to compare the efficacy of every-other-day (Qod) regimen versus twice-a-week (Biw) regimen against recurrence in the remission stage of AD.Methods:A multicenter, randomized, open-label clinical trial was conducted. Totally, 150 children with mild to moderate AD aged 2 - < 18 years were enrolled from 6 hospitals (including Beijing Children′s Hospital, Capital Medical University, etc), and randomly divided into the Qod group (76 cases) and the Biw group (74 cases). In the acute stage of AD, both groups were treated with topical crisaborole 2% ointment on skin lesions twice a day for 2 - 4 weeks, as well as with emollients throughout the whole body. The improvement of early clinical symptoms was evaluated, and the occurrence of adverse reactions was recorded in the follow up. Once the investigator′s static global assessment (ISGA) scores decreased to 1 point or less, the patient would be enrolled into the remission stage. In the remission stage of AD, patients in the Qod group and Biw group were treated with crisaborole ointment every other day and twice a week respectively; the recurrence rate of AD in the remission stage was evaluated, as well as the severity of skin lesions, itching, life quality, and the occurrence of adverse reactions at weeks 4, 8, and 12. Statistical analysis was carried out with SPSS 23.0 software by using t test for comparisons of normally distributed continuous data between two groups, Mann-Whitney U test for non-normally distributed data, chi-square test for enumeration data, and Kaplan-Meier method for analysis of survival rates. Results:A total of 142 patients were enrolled in the modified intention-to-treat population, including 71 in the Qod group and 71 in the Biw group. In the acute stage of AD, the improvement of itching and skin lesions self-reported by the children or their family members occurred on days 1.9 (1.0, 3.0) and 2.0 (1.0, 4.1) after the application of crisaborole ointment, respectively. At the end of treatment in the acute stage, 89 children (62.7%) achieved ISGA 0/1 and successfully transferred into the remission stage. The follow-up in the remission stage was completed in 83 patients (44 in the Qod group and 39 in the Biw group). In addition, recurrence occurred in 19 (43.2%) and 12 (30.8%) patients in the Qod group and Biw group respectively, and there was no significant difference in the recurrence rate between the two groups ( χ2 = 1.36, P = 0.243) ; the average time to recurrence was 64.25 (95% CI: 53.33 - 75.17) days and 75.78 (95% CI: 65.46 - 86.10) days in the Qod group and Biw group respectively. Among the patients who were in the remission stage and had not yet experienced relapse at weeks 4, 8, and 12, there were no significant differences in the eczema area and severity index (EASI) scores, ISGA scores, pruritus numerical rating scale (NRS) scores, or quality-of-life scores between the two groups (all P > 0.05) at any time points, except for the ISGA scores at week 12 (Biw group: 0 [0, 1] point vs. Qod group: 1 [0, 1] point; Z = -2.31, P = 0.021). A total of 146 patients were enrolled in the safety set. During the study period, 70 adverse events occurred in 65 patients, with an incidence rate of 44.5%, and all were mild or moderate adverse events; 55 (37.7%) patients experienced discomfort at the medication site, which mainly referred to pain (45 cases, 30.8%) and mostly occurred in the tender and skinfold areas. Conclusions:Crisaborole 2% ointment could effectively relieve clinical symptoms in children with mild to moderate AD in the early stage, and intermittent treatment could continuously relieve clinical symptoms in the remission stage. The common adverse reaction was discomfort at the application site in the early stage of AD. There was no significant difference in the impact on AD recurrence in the remission stage between the Qod regimen and Biw regimen.

Objective:To investigate the level of serum vascular endothelial growth factor (VEGF) and its correlation with clinical symptoms in patients with first-episode drug-naive schizophrenia patients of different genders.Methods:From January 2016 to October 2019, a total of 81 first-episode drug-naive schizophrenia patients(patient group, 41 male, 40 female) and 64 healthy controls (control group, 40 male, 24 female) were included in this study.The serum level of VEGF was detected with flow cytometric bear array (CBA). Positive and negative symptom scale (PANSS) was used to evaluate the relevant clinical symptoms of patients.SPSS 22.0 software was used for statistical analysis.Independent sample t-test and nonparametric test were used for comparison between groups.The relationship between VEGF and clinical variables was analyzed by Pearson correlation analysis and Spearman correlation analysis. Results:The level of serum VEGF in the patient group was significantly lower than that in the control group(148.08(75.89, 208.61)pg/mL, 179.94(99.14, 318.41)pg/mL, Z=-2.20, P=0.028). The total PANSS score((82.71±17.30), (73.45±16.36), t=2.473, P=0.016)and cognitive score((7.88±3.36), (6.23±2.81), t=2.402, P=0.019) in male patients were higher than those in female patients.There was a negative correlation between VEGF level and PANSS negative symptom score in the patient group( r=-0.228, P=0.041), as well as significant negtive correlation between VEGF level and cognitive score in male patients( r=-0.425, P=0.007). Conclusion:The level of serum VEGF is reduced in first-episode patients with schizophrenia, which influences their negative symptom. Moreover, the decline in serum VEGF level is implicated in cognitive impairments in male patients with first-episode schizophrenia.

Objective:To construct a recombinant herpes simplex virus 2 (HSV-2) expressing enhanced green fluorescent protein (EGFP) using clustered, regularly interspaced, short palindromic repeat/CRISPR-associated nuclease 9 (CRISPR/Cas9) technology.Methods:Four strategies for inserting exogenous EGFP gene into HSV-2 genome using CRISPR/Cas9 technology were designed: (1) conventional homology-directed repair: circular two homology arm donor-mediated gene knock-in; (2) linearized single homology arm donor-mediated gene knock-in; (3) homology-independent targeted integration; (4) conventional homology-directed repair-mediated by cell lines stably expressing Cas9 and sgRNA.Results:The recombinant virus HSV-2-EGFP was successfully constructed based on the second, the third and the fourth strategies. The second strategy was the most efficient, followed by the third and the fourth strategies. The purified recombinant virus could stably express green fluorescent protein in seven passages and shared similar growth characteristics in Vero cells to the parental virus.Conclusions:Linearized single homology arm donor could increase the efficiency of gene knock-in, and cell lines stably expressing Cas9 and sgRNA could increase the efficiency of gene knock-in mediated by homology-directed repair.

Objective:To investigate the effects of genomic location of a foreign gene in Shanghai-191 strain measles virus (MV) vector on gene expression and virus replication.Methods:The nucleotide sequence encoding S1 protein of SARS-CoV-2 was inserted at different positions in MV antigenome (the upstream of the N gene, between P and M genes, between H and L genes), and co-transfected into 293T cells with helper plasmids coding T7 RNA polymerase and N, P, and L proteins, respectively. The transfected cells were lysed and the supernatants were used to infected Vero cells to harvest recombinant viruses. S1 proteins expressed by the recombinant viruses were identified by RT-PCR, indirect immunofluorescence assay, Western blot and ELISA. Growth kinetics of the recombinant viruses were analyzed.Results:Recombinant viruses were failed to be rescued when the S1 protein-coding sequence was cloned into the upstream of N gene. Two recombinant viruses, MV-M-S1 and MV-L-S1, were successfully rescued when cloning the S1 protein-coding sequence into the intergenic region between P and M genes, or H and L genes, and could express S1 protein. MV-M-S1 expressed more S1 protein than MV-L-S1, but the titer of MV-M-S1 was lower.Conclusions:Inserting a foreign gene at different positions in the MV genome might have different effects on gene expression and virus replication. This study provided reference for the subsequent construction of MV vector.

Objective:To observe the application effect of Rothman-Keller risk forewarning model on stroke incidence in elder community patients with hypertensive.Methods:A total of 1 267 elder hypertensive patients were selected as research objects from 4 community hospitals cooperated with Xinxiang Central Hospital in June 2018. 12 related risk factors were collected according to the Rothman-Keller model, including systolic blood pressure, diastolic blood pressure, high density liptein cholesterol (HDL-c) , low density lipoprotein (LDL-c) , homocysteine (Hcy) , Hyperuricemia, impaired fasting glucose/diabetes, family history of stroke, carotid plaque positive, regular medication, physical exercise and smoking. The differences on risk factors were compared among patients with different characteristics. The patients were followed up in June 2019 and June 2020 respectively. The follow-up mainly included blood pressure control, stroke incidence and death. Rothman-Keller model was used to evaluate the risk of stroke in elderly patients with hypertension in the general population and different gender groups, and the application effect of the model was analyzed.Results:Among 1 267 patients with hypertension, 54 cases were lost to follow-up, and the loss rate was 4.26%. The follow-up time was (43.40±8.22) months. The systolic blood pressure, LDL-c, the proportion of smoking and the positive rate of carotid plaque in male patients were significantly higher than those in female patients, with statistical significance ( P<0.05) . The sensitivity, specificity and diagnostic coincidence rate of Rothman-Keller model for stroke in general population, male population and female population were 0.82, 0.76, 75.93%; 0.86, 0.82, 81.78%; 0.73, 0.83, 82.61%, respectively. According to Rothman-Keller model, the area under the receiver operating characteristic (ROC) curve of stroke in total population, male population and female population were 0.773, 0.784 and 0.824 respectively ( P<0.01) . Conclusions:Rothman-Keller model can well predict the risk of stroke in elderly patients with hypertension in the community. It is a simple and practical prediction tool.

Objective:To explore the effect of supportive-expressive group therapy (SEGT) on alexithymia in patients with lung cancer.Methods:Totally 62 lung cancer patients were divided into control group( n=30) and intervention group( n=32) by coin flipping method.The intervention group received 6-week supportive-expressive group therapy and the intervention path was improved by action research method.There was no special intervention in the control group.The Toronto alexithymia scale (TAS-20) and hospital anxiety and depression scale (HADS) were used for measurement, and statistical analysis was carried out by SPSS 21.0. Results:The emotional recognition disorder (Wald groupχ 2=6.055, Wald interactionχ 2=15.157), emotional description disorder (Wald groupχ 2=5.736, Wald interactionχ 2=28.912), TAS-20 (Wald groupχ 2=7.181, Wald interactionχ 2=28.126), anxiety (Wald groupχ 2=4.905, Wald interactionχ 2=30.491), depression (Wald groupχ 2=9.580, Wald interactionχ 2=29.417) and HADA (Wald groupχ 2=8.140, Wald interactionχ 2=47.851) had significant group effect and interaction effect at the pre-test, post-test and 1 month after intervention(all P<0.05). There was no significant group effect in extroverted thinking (Wald groupχ 2=1.161, P>0.05), but the time effect (Wald timeχ 2=6.381, P<0.05) and the interaction effect (Wald interactionχ 2=6.339, P<0.05) were significant in the three time points.The group effect of emotional recognition disorder, emotional description disorder, TAS-20, anxiety, depression and HADA score at completed intervention and 1 month after intervention were significant(all P<0.05). Compared with before intervention, TAS-20((52.94±4.77) , (52.06±4.07)), emotional recognition disorder((17.72±2.23) , (17.78±1.64)), emotional description disorder((13.44±1.94) , (13.41±1.79)), HADA((14.41±2.63) , (13.75±2.97)), anxiety ((7.03±1.64), (6.84±1.51)), depression ((7.38±1.45) , (6.91±1.75) ) at completed intervention and 1 month after intervention decreased ( P<0.05), while the HADS of control group only decreased at completed intervention ( P<0.05). Conclusion:SEGT can reduce alexithymia in lung cancer receiving chemotherapy, and this intervention has positive effect on improving anxiety and depression in lung cancer patients received chemotherapy who are accompanied with emotional cognitive impairment and emotional somatic symptom recognition disorder.
