ABSTRACT
Objective:To investigate the clinical efficacy of anal dimple anorectoplasty on female infants with congenital anal atresia combined rectal vestibular fistula.Methods:Clinical data of 69 female infants with congenital anal atresia combined rectal vestibular fistula admitted to Department of Pediatric Surgery, the First Affiliated Hospital of Zhengzhou University from July 2012 to July 2022 were retrospectively analyzed.They were divided into 2 groups according to the surgical methods: 34 cases of anal dimple anorectoplasty(group A) and 35 cases of anterior sagittal anorectoplasty(group B). The operation time, length of stay, short-term complications, long-term complications and bowel function (determined by the Rintala score at 6 months postoperatively) of the two groups were compared.The difference in the incidence of postoperative complications between groups was compared by Chi- square test, and the remaining differences between groups were compared by the paired t-test. Results:The operative time [(80.18±9.29) min vs.(103.85±8.26) min] and postoperative hospital stay[(6.10±1.52) d vs.(7.63±2.40) d] in group A were significantly shorter than those of group B ( t=11.40, 2.62; all P<0.05). The Rintala total score at 6 months postoperatively in group A was significantly higher than that of group B[(19.36±0.93) points vs.(18.76±0.44) points]( t=3.20, P<0.05). There were no significant differences in the incidences of short-term [(4/34, 11.8%) vs.(7/35, 20.0%)] and long-term complications [(2/34, 5.9%) vs.(4/35, 11.4%)]between group A and group B ( χ2=0.75, 0.75; all P>0.05). Conclusions:Anal dimple anorectoplasty for female infants with congenital anal atresia combined rectal vestibular fistula is safe and effective.
ABSTRACT
Objective:To determine the expression of T follicular helper (Tfh) cell-related molecules inducible costimulator (ICOS) and programmed cell death-1 receptor (PD-1) in skin lesions of patients with bullous pemphigoid (BP), and to explore the role of Tfh cells in the pathogenesis of BP.Methods:Twenty-one paraffin-embedded tissue specimens were collected from 21 patients with confirmed BP in Dalian Dermatosis Hospital from 2014 to 2017, including 7 females and 14 males with an average age of 72.57 years. Ten normal skin tissue specimens served as control group. Immunohistochemical SP method was used to determine the expression of ICOS and PD-1 in BP skin lesions and normal skin tissues.Results:In BP lesions, ICOS and PD-1 were mainly expressed in the basal layer, spinous layer, granular layer and stratum corneum, especially in the spinous layer in the epidermis, and also expressed in inflammatory cells in the dermis. Additionally, they were both expressed in the cytoplasm and nuclei, occasionally expressed on the cell membrane. However, ICOS and PD-1 were rarely expressed in the normal skin tissues. The expression rates of ICOS and PD-1 were significantly higher in the BP group (85.71% [18/21], 47.62% [10/21], respectively) than in the normal control group (both were 0; P < 0.001, < 0.05, respectively) .Conclusion:Tfh cell-related molecules ICOS and PD-1 may play important roles in the pathogenesis of BP.
ABSTRACT
Objective:To investigate the effect of long-term low dose ionizing radiation on the levels of interleukin (IL) and TGF-β1 in the population in high background radiation area(HBRA).Methods:Appropriate amount of peripheral blood was drawn from 41 and 44 healthy men aged 45-65 years who were randomly selected from Tangkou town of Yangjiang city (HBRA) and Hengpo town of Enping city (control area, CA), respectively. After centrifugation and stratification, the upper plasma of blood was separated to determine IL-2, sIL-2R, IL-4, IL-5 and TGF-β1 by using ELISA. The difference of plasma IL of the residents in those two regions was analyzed. The influence of region, age, smoking, drinking and income on the indexes of ILs and TGF-β1 was evaluated by Covariance analysis.Results:The concentration of IL-2 at HBRA area was slightly higher than those in the control area, but the other indexes were lower than those in CA residents. The differences of IL-5 ( t=7.124, P<0.001) and TGF-β1 ( t=4.900, P<0.001) between two areas were significant statistically. Covariance analysis showed that smoking had a significant effect on IL-2 level ( F=5.283, P<0.05). Conclusions:Under the influence of long-term low-dose ionizing radiation, all kinds of plasma interleukin levels of residents in HBRA were different with that in CA. The immune balance was biased towards Th1 type cytokines, and the immune function in HBRA was slightly stronger than that in CA, suggesting that long-term chronic low-dose ionizing radiation may induce adaptive changes in the immune function, which needs further study.

ABSTRACT
Objective@#To explore the mediating effect of hemoglobin (Hb) and hematocrit (HCT) on the association between alcohol consumption and blood pressure, and provide evidence for the prevention and control of alcohol-attributed hypertension.@*Methods@#1 091 male (age >50 years old) participants with drinking habit were selected from the Guangzhou biobank cohort study (GBCS). Mediation analysis was used to evaluate the mediating effect of Hb and HCT on the association of alcohol consumption (unit/day) with systolic blood pressure (SBP), diastolic blood pressure(DBP), pulse pressure(PP) and mean arterial pressure (MAP).@*Results@#After adjusting for age, body mass index, education level, personal annual income, smoking, occupation and physical activity, the associations of alcohol consumption with SBP, DBP, PP and MAP were partly mediated by Hb, the proportion of mediating effect was 11.8% (95%CI 4.8%-24.7%), 15.3% (95%CI 6.5%-32.0%), 8.4% (95%CI 2.2%-22.5%) and 13.5% (95%CI 5.9%-27.5%), respectively. The associations of alcohol consumption with SBP, DBP, and MAP were also partly mediated by HCT, the proportion of mediating effect was 6.3% (95%CI 1.0%-16.0%), 8.7% (95%CI 1.4%-21.4%), and 7.5% (95%CI 1.0%-18.6%), respectively.@*Conclusion@#There is a significant mediating effect of Hb and HCT on the association between alcohol consumption and blood pressure. Besides efforts on alcohol control, the potential effects of alcohol-induced increase on Hb and HCT, which might also increase the blood pressure, need to be considered to achieve optimal monitoring and prevention of alcohol-related hypertension.
ABSTRACT
Objective To examine the association between weight changes during early and middle adulthood and the risk of type 2 diabetes mellitus in middle aged and elderly population.Methods Based on the Guangzhou Biobank Cohort Study (GBCS),28 736 residents aged ≥50 years were included in Guangzhou.Multivariate logistic regression was used to analyze the association between body weight changes during early or middle adulthood and age when the heaviest weight reaching the threshold on the risk of type 2 diabetes mellitus in middle age or elderly population.Adjustments on age,smoking,alcohol consumption,physical activity,education level,occupation,district of residence and body mass index etc.,were made.Results The mean age was 64.3 (standard deviation=6.7) years in men and 61.0 (standard deviation=7.0) years in women,with the prevalence rates of diabetes as 13.1％ and 13.7％ in men and women,respectively.Compared to those with stable body weight,the risk of diabetes increased with weight gain during early and middle adulthood in both men and women (both P values for trend ＜0.01).Participants who gained more than 20 kg during early and middle adulthood were associated with the highest risk of diabetes in men (OR=2.83,95％ CI:1.99-4.02) and women (OR=3.13,95％CI:2.47-3.96).Compared to those who reached the highest weight at age 20,those who reaching the highest weight at 40 to 49 years were associated with the highest risk of diabetes,with OR being 5.32 (95％CI:1.92-14.8) in men and 3.41 (95％CI:2.49-4.67) in women,respectively.Weight loss in adulthood was associated with self-reported but not newly diagnosed diabetic cases in both middle and older aged men and women.Conclusion Weight gain during early and middle adulthood may increase the risk of diabetes in middle and older aged population.The detrimental effect of obesity on diabetes might become significantly visible in the next decades.

ABSTRACT
OBJECTIVE: To investigate the current status and influencing factors of occupational stress in female workers of labor-intensive enterprises. METHODS: Totally 910 female workers from 5 labor-intensive enterprises in Guangdong Province was selected as the research subjects by random cluster sampling method. A questionnaire survey on occupational stress was conducted using the Occupational Stress Inventory-Revised Edition. RESULTS: Among the 910 female workers,14. 9%( 136/910) showed medium or higher scale on occupational role level,20. 1%( 183/910) showed medium or higher scale on occupational stress level,and 21. 4%( 195/910) showed medium or higher scale on personal resources lack. Multivariate logistic regression analysis indicated that the risk of occupational stress was high in single female workers and/or those exposed to occupational hazards( P < 0. 01). The higher the occupational role level,the higher risk of occupational stress( P < 0. 01). The less personal resources,the higher risk of occupational stress( P < 0. 01).CONCLUSION: Some female workers in labor-intensive enterprises showed medium or higher occupational stress level. The main influencing factors of occupational stress are marital status,exposure to occupational hazards,occupational role and personal resources.
ABSTRACT
OBJECTIVE: To analyze the influencing factors that cause occupational stress among female workers in a large electronic manufacturing enterprise. METHODS: A total of 1 081 female workers from a large electronic manufacturing enterprise were selected by the cluster random sampling method. The Chinese version of Job Content Questionnaire and Effort Reward Imbalance Questionnaire were used to assess occupational stress and its influencing factors were analyzed.RESULTS: Among 1 081 female workers,70. 95% and 19. 43% of them showed high level of occupational stress of job demand-control( JDC) model and effort-reward imbalance( ERI) model,respectively. Educational level with senior high school and above,assembly line working and exposure to occupational hazards were risk factors for high occupational stress of JDC model in female workers( P < 0. 01). The risk of high occupational stress ERI model in female workers with junior high school educational level and below was higher than that of senior high school educational level and above( P < 0. 01).CONCLUSION: The occupational stress rate of female workers in this electronic manufacturing enterprise is high. The main occupational stress model is JDC model. The main influencing factors of JDC model are educational level,operation mode and status of occupational hazard exposure.
ABSTRACT
Objective To examine the association of fasting plasma glucose (FPG) and serum uric acid (SUA) in middle and elderly Chinese. Methods 10 413 Guangzhou residents aged ≥50 were included in the present study. Information on personal history,physical examination and biochemical parameters were collected. Subjects were grouped by the FPG level,association between FPG and SUA. Levels of hyperuricemia(HUA)were evaluated. Results The SUA levels and the incidence of HUA showed trends of increasing,with the increasing FPG levels in women,with statistically significant differences seen among all the FPG groups(P value for trend<0.05). While the statistical differences of SUA levels and the incidence rates of HUA among diabetes group(DM group)and impaired fasting glucose(IFG)groups were non-significant(P>0.05)but it was higher than normal FPG group in men (P<0.05). Logistic regression models were built between various FPG groups and HUA. After adjusting for age,smoking status,drinking status,physical activity, hypertension,body mass index and the levels of triglyceride and creatin. When compared to the normal FPG group,the risk of women suffering from HUA increased by 40%(95%CI:1.19-1.64) under the FPG in the range of 6.1-6.9 mmol/L. Compared to those non-diabetic individuals,the risk of diabetic patients suffering from HUA also increased by 44%(95%CI:1.15-1.79) in women. However,the risk of suffering from HUA did not relate to the increase of FPG in men. Conclusion The SUA level and the incidence of HUA tended to increase along with the increasing levels of FPG in middle and elderly Chinese women and the increase of FPG might also increase the risk of HUA,but not in men.

Objective To investigate the serum levels of tumor markers CEA,CA724,PGⅠ,PGⅡ,PGI/PGII and SF in gas-tric cancer.Methods The serum levels of CEA,CA724,PGⅠ,PGⅡ,PGI/PGII and SF were detected in 46 healthy con-trols,45 atrophic gastritis patients and 39 gastric cancer patients.Serum levels of CEA,CA724 were measured by ELC meth-od,PGⅠ,PGⅡ by time resolved fluorescence immunoassay (TRFIA)and SF by immunoturbidimetry(ITM).Results ①Compared to the healthy controls,the statistical contrast of serum levels of CEA,CA724,PGⅠ,PGⅡ and PGI/PGII except SF was significant in gastric cancer patients(P<0.05),only PGⅠ,PGⅡ,SF had significant difference in atrophic gastritis patients (P<0.05).Compared to atrophic gastritis patients,the serum levels of CEA,CA724 were significantly higher,but PGⅠwas lower in gastric cancer patients(P<0.05).②When CEA,CA724,PGⅠ,PGⅡ,PGI/PGII and SF were used to di-agnose gastric cancer individually,the sequence of the area under ROC curve was CEA,SF,CA724,PGI/PGII,PGⅡ and PGⅠ.Only the areas of PGⅠ,PGⅡunder ROC curve had significant statistical difference (P<0.05).③The sensitivity,speci-ficity,PPV and NPV were different when these indexes were used to diagnize gastric cancer individually or incorporatedly. Conclusion The serum levels of tumor markers CEA,CA724,PGⅠ,PGⅡ,PGI/PGII and SF had important reference value for the diagnosis of gastric cancer although the diagnostic value was different individually or incorporatedly;the content of serum PG and the ratio of PGI/PGII were closely related to the gastric mucosa.
ABSTRACT
Objective To investigate the prevalence and charateristics of carotid atherosclerosis among healthy middle-aged people of community. Methods Totally 1930 subjects aged 50 years and above were selected randomly from 10027 participants recruited during Phase 3 of the Guangzhou Biobank Cohort Study (GBCS).Common carotid artery intima-media thickness (CCA-IMT) and carotid plaques (CP) were measured by B-mode ultrasonography using ALT HDI 3000 mainframe with a high-resolution. Results The prevalences of CCA-IMT and CP in men were higher than women [41.5％(400/963)vs.16.2 (157/967),34.1％ (328/967) vs.13.8％ (133/967),both P＜0.001].The prevalence of CCA-1MT was higher with age increasing in either men or women in groups of 50-yrs,60-yrs and 70-79 yrs (all P＜0.001).The most of CP was cankerous spot (37.8％),secondly hard spot (24.9％),soft spot (22.1％) and the prevalence of flat spot was lowest (15.2％).The number of CP was not significantly different between the left and right side (51.0％ and 49.0％).The most common location of CP was bifurcations of carotid arteries (61.7 ％),next the common carotid artery (21.0％) and internal carotid artery (ICA) was lowest (17.3 ％).The prevalence of CP was 44.4％ (83/87) in women aged 50- yrs,it was higher than that in men 20.9％ (108/517).However,the prevalence of CP was 79.1％ (409/517) in men aged more than 60 yrs,higher than that in women (55.6％). Conclusions The carotid atherosclerosis is commonly encountered disease in the male elderly,and the most of CP was cankerous spot in bifurcations of carotid arteries
ABSTRACT
Objective To explore weaning dependent patients off mechanical ventilation through rehabilitative treatment. Methods Eighty-four patients dependent on mechanical ventilation were randomly divided into a rehabilitation group (n =44) and a control group (n =40). All were treated with routine medication, but in addition patients in the rehabilitation program followed a rehabilitation program. Three weeks later, the success rates and the time of weaning off mechanical ventilation were observed in the two groups. Results In the rehabilitation group,88.6% of the patients were successfully weaned off mechanical ventilation, versus 60% of the control group. The respective average weaning times were 6.8 ± 3.8 days and 14.3 ± 5.2 days. Both differences were statistically significant. Conclusions Rehabilitative treatment improves the weaning success rate and reduces the time needed for weaning mechanical ventilation-dependent patients.
ABSTRACT
Office blood pressure has been regarded as a gold standard of blood pressure measurements.It is an important indicator of ensurement of correct diagnosis,management of condition and evaluation of prognosis.But limitations of office blood pressure have led to the increasing use of out-of-office blood pressure.Many evidence show that out-of-office blood pressure could more accurately reflex variability of blood pressure and rhythm of blood pressure.Out-of-office blood pressure could diagnose white-coat hypertensives or masked hypertensives without delay,properly determine the need for antihypertensive treatment and decrease risk of developing blood pressure-related complications.
ABSTRACT
Objective:Eighteen inorganic elements were measured from the rhizoma and fibrous root of Polygonatum Cyrtonema Hua. The contents of K, Fe,Mg,Ba,Cu,Mn and Bi of them in rhizoma were higher than that of fibrous root, where as the contents of Na,Al,Ca,Ge,P,Zn and Sr elements in rhizoma were lowere than that of fibrous. Both contained As,Hg,Pb and Cd elements. In the meantime, 16 mino acid were determined. The total content of them was 8.92% for rhizoma and 9.61% for fibrous. Cystine, cysteine, tryptophan and ornithine couldn't be detected.
