OBJECTIVESince the outbreak of a highly contagious new pneumonia, atypical pneumonia or severe acute respiratory syndrome (SARS) occurred in Guangzhou area, 33 children with this syndrome were treated in the authors' hospital. The present study aimed to understand clinical characteristics and prognosis of pediatric SARS patients in Guangzhou area.

METHODSClinical manifestations, laboratory and radiologic findings, therapeutic approaches and prognosis of the 33 children with SARS in Guangzhou area were analyzed.

RESULTSOf the 33 cases, 17 were males and 16 were females. The age was between 3 months to 13 years, and 3 - 12 years old patients accounted for 82%. Five (15%) cases had an evident history of contacting SARS patient before the symptoms occurred. Another 5 (15%) cases had a history that contacts of these patients (family members or friends) developed fever and/or cough later. The most common symptoms in this cohort were fever (100%) and cough (91%). Most of the cases had high fever, higher than 39 degrees C. Near half of the cases had nonproductive cough. The initial blood cells count showed that total white blood cell (WBC) count was (2.5 - 9.7) x 10(9)/L. In 22 (67%) cases the WBC count was < 5.0 x 10(9)/L, and in 10 (30%) WBC was (5.0 - 7.0) x 10(9)/L, in 18 cases most of the WBC were lymphocyte count. Chest radiograph showed patchy infiltrates, in 15 cases the changes were unilateral, and in 18 were bilateral. The radiologic changes developed fast, in some cases the changes progressed from one side to both sides. The opacity was absorbed slowly, significant absorption took in average two weeks. Elevated ALT was found in 3 cases and elevated CK-MB in 2 cases. Treatment included isolation, good ventilation of the ward, bed rest, supportive regimens, low volume oxygen inhalation, use of Chinese traditional medicine, antibiotics to prevent bacterial infection, and anti-inflammation therapy. All the patients recovered and discharged from hospital after a mean period of 10.0 +/- 3.8 days.

CONCLUSIONSARS in children may have its own characteristics. The main clinical manifestations were high fever and cough while no severe toxic symptoms, nor respiratory failure was seen; few symptoms or signs suggesting involvement of systems other than respiratory system were seen. Chest radiograph showed uni- or bilateral asymmetric air-space infiltrates which could worsen quickly and were absorbed slowly. Though there were severe changes in the lung, the patients might not have corresponding symptoms or signs. The total white blood cell count in peripheral blood did not increase. All the patients studied had a favorable outcome after the combined treatment.

Objective:To explore the influencing factors for compliance to colonoscopy screening for colorectal cancer in outpatients.Methods:Patients aged 40-74 years who visited the outpatient gastroenterology department of 7 tertiary hospitals in 7 regions of Xinjiang from January 2022 to June 2022 were enrolled. Recommendations for colonoscopy screening were made according to the patient's medical conditions, and the questionnaire was used to collect information. The Chi-square test was used to compare the differences of compliant and non-compliant patients. Multivariate logistic regression was used to analyze the influencing factors of compliance to colonoscopy screening.Results:A total of 463 valid questionnaires were obtained from 7 centers, in which, 427 outpatients (92.2%) followed the recommendation for colonoscopy screening, and 36 (7.8%) did not. Chi-square test results showed that there were statistically significant differences between the two groups in gender, age, education, subjective cognition of intestinal polyps, personal history of colorectal polyps, family history of colorectal cancer, family history of colorectal polyps, abdominal pain or distension, and defecation habit or stool changes ( P<0.05). The results of multivariate regression analysis showed that the screening compliance of patients aged 40-49 years ( P=0.005, OR=0.141, 95% CI: 0.036-0.549) and 50-59 years ( P=0.039, OR=0.257, 95% CI: 0.071-0.932) was lower than that of patients aged 60-74 years. The screening compliance of patients with high school education ( P=0.011, OR=3.121, 95% CI: 1.304-7.473) and college education or above ( P=0.016, OR=3.544, 95% CI: 1.270-9.890) was higher than those with primary school education and below. Patients with personal history of colorectal polyps ( P=0.015, OR=12.288, 95% CI: 1.629-92.719), family history of colorectal cancer ( P=0.038, OR=8.506, 95% CI: 1.124-64.351) and changes in defecation habit or stool trait ( P=0.039, OR=4.794, 95% CI: 1.085-21.192) also had higher compliance. Conclusion:Age, educational level, personal history of colorectal polyps, and family history of colorectal cancer are related to colonoscopy screening compliance in outpatients of 7 tertiary hospitals in 7 regions of Xinjiang. The independent risk factors affecting compliance to colorectal cancer screening in outpatients are age of 40-59 years, lower educational level, no previous history of polyps or family history of colorectal cancer, and no defecation habit or stool changes.

BACKGROUNDThe severity of respiratory distress was associated with neonatal prognosis. This study aimed to explore the clinical characteristics, therapeutic interventions and short-term outcomes of late preterm or term infants who required respiratory support, and compare the usage of different illness severity assessment tools.

METHODSSeven neonatal intensive care units in tertiary hospitals were recruited. From November 2008 to October 2009, neonates born at ≥ 34 weeks' gestational age, admitted at < 72 hours of age, requiring continuous positive airway pressure (CPAP) or mechanical ventilation for respiratory support were enrolled. Clinical data including demographic variables, underlying disease, complications, therapeutic interventions and short-term outcomes were collected. All infants were divided into three groups by Acute care of at-risk newborns (ACoRN) Respiratory Score < 5, 5 - 8, and > 8.

RESULTSDuring the study period, 503 newborn late preterm or term infants required respiratory support. The mean gestational age was (36.8 ± 2.2) weeks, mean birth weight was (2734.5 ± 603.5) g. The majority of the neonates were male (69.4%), late preterm (63.3%), delivered by cesarean section (74.8%), admitted in the first day of life (89.3%) and outborn (born at other hospitals, 76.9%). Of the cesarean section, 51.1% were performed electively. Infants in the severe group were more mature, had the highest rate of elective cesarean section, Apgar score < 7 at 5 minutes and resuscitated with intubation, the in-hospital mortality increased significantly. In total, 58.1% of the patients were supported with mechanical ventilation and 17.3% received high frequency oscillation. Adjunctive therapies were commonly needed. Higher rate of infants in severe group needed mechanical ventilation or high frequency oscillation, volume expansion, bicarbonate infusion or vasopressors therapy (P < 0.05). The incidence of complications was also increased significantly in severe group (P < 0.05). The in-hospital mortality in the severe group was significantly higher than other two groups (P < 0.05). ACoRN Respiratory Score was correlated with Score for Neonatal Acute Physiology-Version II (SNAP-II) (P < 0.01). High gestational age, high SNAP-II score and oxygenation index (OI), and Apgar score at 5 minutes < 5 were independent risks for death.

CONCLUSIONSNeonatal respiratory distress is still a common cause of hospitalization in China. Illness severity assessment is important for the management. ACoRN Respiratory Score which correlated with SNAP-II score is easy to use and may be helpful in facilitating the caregivers in local hospital to identify the early signs and make the transfer decision promptly.

Objective:To investigated the prevalence of anxiety and depression symptoms in patients with colorectal polyps in part of Xinjiang area and to explore the associated influencing factors related to psychological status, and to provide evidence and clues to promote the diagnosis and treatment of psychosomatic diseases in digestive system.Methods:From December 2021 to June 2022, at the First Affiliated Hospital of Shihezi University, the Fourth Division Hospital of Xinjiang Production and Construction Corps, the Third Division Hospital of Xinjiang Production and Construction Corps (Kashgar Hospital), the Thirteenth Division Red Star Hospital of Xinjiang Production and Construction Corps, the Tenth Division Beitun Hospital of Xinjiang Production and Construction Corps, the Seventh Division Hospital of Xinjiang Production and Construction Corps, the Fifth Division Hospital of Xinjiang Production and Construction Corps, patients who underwent colonoscopy and colorectal polyps detected were enrolled. The generalized anxiety disorder scale-7 (GAD-7) was used to screen anxiety symptoms, and the patient health questionaire-8 (PHQ-8) was performed to screen depression symptoms, and the general situation questionnaire was used to collect clinical information of patients. The questionnairs were completed via the Questionnaire Star platform or paper questionnaire, and a database was established. The patients were divided into groups according to whether with anxiety and depression symptoms. Multivariable logistic regression models was performed to analyze the factors related to anxiety and depression.Results:A total of 516 questionnaires were distributed and collected, among which 9 questionnaires were incomplete and 507 questionnaires were valid, the effective rate of questionnaires was 98.26%. The detection rates of anxiety and depression symptoms in 507 patients with colorectal polyps were 21.50%(109/507) and 19.33%(98/507), respectively. The results of multivariable logistic analysis revealed that female ( OR=3.87, 95% confidence interval (95% CI) 2.30 to 6.51, P<0.001), maximum diameter of polyp ( OR=1.74, 95% CI 1.14 to 2.67, P=0.011), perception of polyps as cancer ( OR=13.96, 95% CI 1.48 to 132.07, P=0.022), and the occurrence of gastrointestinal symptoms after polyp detection ( OR=5.43, 95% CI 1.74 to 16.92, P=0.004) were independent risk factors of anxiety in patients with colorectal polyps. Female ( OR=2.42, 95% CI 1.47 to 4.00, P=0.001), the number of polyps ( OR=1.07, 95% CI 1.01 to 1.13, P=0.028) and the count of gastrointestinal symptoms ( OR=2.04, 95% CI 1.34 to 3.10, P=0.001) were independent risk factors of depression in patients with colorectal polyps. Conclusion:Gender, polyp size, number of polyps, disease perception, and concomitant gastrointestinal symptoms are associated with anxiety and depression in patients with colorectal polyps.

OBJECTIVETo investigate the clinical features of unexpected sudden death (SUD) clustered in families in Yunnan province.

METHODSThis retrospective study analyzed the clinical features of SUD occurred between July to September 2005 in 7 families in Yunnan province.

RESULTSAll 16 SUD patients shared common clinical features such as fatigue and repeated syncope and one group of SUD patients (n = 8 from 4 families) presented with the gastric intestinal tract manifestations including nausea, vomiting, abdominal pain and diarrhea with suspected dietary history and abnormal laboratory enzyme findings (GOT/GPT, CK/CKMB, LDH/LDH1 etc.). In SUD patients without gastric intestinal tract manifestations (n = 8 from 3 families), there were no clear symptoms before death and repeated ventricular tachycardia and ventricular fibrillation were recorded in one survivor. There was no clear evidence for the involvements of hereditary and infectious factors for observed SUD.

CONCLUSIONThe reason for the unexpected sudden death clustered in 7 families in Yunnan remains unclear. Repeated syncope and fatigue served as the common clinical features in the presence or absence of gastric intestinal tract manifestations in all SUD cases. Further studies are needed to clarify the pathology and detailed clinical manifestations of SUD occurred in this area.

Objective:To analyze the fail mode of neoadjuvant therapy combined with surgery for locally advanced esophageal squamous cell carcinoma (ESCC) after long-term follow-up.Methods:Clinical data of consecutive 238 patients with locally advanced resectable ESCC who underwent neoadjuvant therapy combined with surgery in Zhejiang Cancer Hospital from September 2012 to October 2019 were retrospectively analyzed. The failure mode in the whole cohort was analyzed after long-term follow-up. The overall survival (OS) and disease free survival (DFS) rates were analyzed by Kaplan-Meier method. Survival differences were determined by log-rank test.Results:The pathological complete response (pCR) rate was 42.0% in 238 patients. After a median follow-up of 46.1 months, tumor progression occurred in 96 patients (40.3%), including 25 patients (10.5%) with local recurrence, 61 patients (25.6%) with distant metastases, and 10 patients (4.2%) with simultaneous local recurrence and distant metastases. The median OS and DFS were 64.7 months and 49.9 months. And the 3-, 5-, and 7-year OS and DFS rates were 70.0%, 52.8%, 36.4% and 63.5%, 42.5%, and 30.0%, respectively. The 3-, 5-, and 7-year locoregional recurrence-free survival rates and distant metastasis-free survival rates were 86.0%, 71.4%, 61.2% and 70.6%, 55.9%, 43.0%. Compared with non-pCR patients, the overall progression rate and distant metastasis rate of pCR patients were lower (26.0% vs. 50.7%, 16.0% vs. 32.6%, both P<0.05). And the 3-, 5-, and 7-year OS (83.0% vs. 60.2%, 69.7% vs. 41.7%, 50.4% vs. 27.7%, all P<0.001) and DFS rates (80.4% vs. 51.4%, 63.9% vs. 31.2%, 45.9% vs. 20.3%, all P<0.001) were significantly better in pCR patients. Conclusions:Distant metastasis is the main failure mode of patients with locally advanced ESCC after neoadjuvant therapy. Patients with postoperative pCR can achieve better long-term survival.

BACKGROUNDAtherosclerosis (AS) is an inflammatory disease. Inflammation was considered to play a role in the whole process of AS. This study aimed to analyze the relationships of inflammatory factors and risk factors with different target organ damages (TOD) in essential hypertension (EH) patients and to explore its clinical significance.

METHODSA total of 294 EH patients were selected and divided into four groups according to their conditions of TOD. Forty-eight healthy subjects were selected as control. The clinical biochemical parameters, serum amyloid A, serum tryptase, and lipoprotein-associated phospholipase A2 (Lp-PLA2) in each group were detected, and the related risk factors were also statistically analyzed.

RESULTSFibrinogen (Fbg) was the most significant independent risk factor in acute coronary syndrome (ACS) group (odds ratio [OR]: 22.242, 95% confidence interval [CI]: 6.458-76.609, P< 0.001) with the largest absolute value of the standardized partial regression coefficient B' (b': 1.079). Lp-PLA2 was the most significant independent risk factor in stroke group (OR: 13.699, 95% CI: 5.236-35.837, P< 0.001) with b' = 0.708. Uric acid (UA) was the most significant independent risk factor in renal damage group (OR: 15.307, 95% CI: 4.022-58.250, P< 0.001) with b' = 1.026.

CONCLUSIONSFbg, Lp-PLA2, and UA are the strongest independent risk factors toward the occurrence of ACS, ischemic stroke, and renal damage in EH patients, thus exhibiting the greatest impacts on the occurrence of ACS, ischemic stroke, and renal damage in EH patients, respectively.

Background: Our previous studies have shown that regulatory factor X5 (RFX5), a classical transcription regulator of MHCII genes, was obviously overexpressed in hepatocellular carcinoma (HCC) tumors. However, the role of RFX5 in the carcinogenesis and progress of HCC remains unknown. This study aimed to reveal its biological significance and the underlying mechanism in HCC. Methods: RFX5 mRNA expression level and copy number variation in HCC tumors and cell lines were determined by analyzing deposited data sets in the Cancer Genome Atlas and Gene Expression Omnibus database. The biological significance of RFX5 in HCC was investigated by monitoring the colony formation and subcutaneous tumor growth capacity when RFX5 was silenced with lentiviral short hairpin RNA and CRISPR/Cas9 system in HCC cell lines. The downstream gene transcriptionally activated by RFX5 in HCC cells was determined by chromatin immunoprecipitation and luciferase reporter assay. The involvement of tyrosine 3-monooxygenase/tryptophan 5-monooxygenase activation protein theta (YWHAQ) in HCC development was further determined by performing colony formation rescue assay and subcutaneous tumor growth rescue experiment. The association of YWHAQ with recurrence-free survival of patients with HCC was assessed by Kaplan-Meier analysis. Moreover, apoptosis level and the protein level of p53 pathway were determined to reveal the mechanism of RFX5 in driving HCC development. Results: RFX5 was amplified and highly overexpressed in HCC tumor tissues compared with the corresponding non-tumor tissues. The mRNA expression level of RFX5 was significantly correlated with its DNA copy number (r = 0.4, P < 0.001). Functional study demonstrated that RFX5 was required for both clonogenic forming in vitro and subcutaneous tumor growth in vivo of HCC cells. Further study identified YWHAQ, namely 14-3-3 tau, as a key downstream transcriptional target gene of RFX5, which was tightly regulated by RFX5 in HCC. Moreover, overexpression of YWHAQ largely rescued the clonogenic growth of HCC cells that was suppressed by RFX5 knockdown. In addition, overexpression of YWHAQ in primary tumor was linked to poor prognosis of patients with HCC. These results demonstrated that YWHAQ was a downstream effector of RFX5 in HCC. Notably, RFX5-YWHAQ pathway could protect cells from apoptosis by suppressing the p53 and Bax in HCC. Conclusion RFX5 is a putative HCC driver gene that plays an important role in the development and progression of HCC by transactivating YWHAQ and suppressing apoptosis.

OBJECTIVETo study the effectiveness of waist circumference cut-off values in predicting the prevalence of metabolic syndrome (MetS) and risk factors in adults in China.

METHODSA cross-sectional survey was condcuted in 14 provinces (autonomous region, municipality) in China. A total of 47,325 adults aged⋝20 years were selected by multistage stratified sampling, and questionnaire survey and physical and clinical examination were conducted among them. MetS was defined according to the International Diabetes Federation (IDF) criteria and modified IDF criteria.

RESULTSThe age-standardized prevalence of MetS was 24.2% (22.1% in men and 25.8% in women) and 19.5% (22.1% in men and 18.0% in women) according to the IDF criteria and modified IDF criteria respectively. The age-standardized prevalence of pre-MetS was 8.1% (8.6% in men and 7.8% in women) according to the modified IDF criteria. The prevalence of MetS was higher in urban residents than rural residents and in northern China residents than in southern China residents. The prevalence of central obesity was about 30% in both men and women according to the ethnicity-specific cut-off values of waist circumference for central obesity (90 cm for men and 85 cm for women). Multivariate regression analysis revealed no significant difference in risk factors between the two MetS definitions.

CONCLUSIONUsing both the modified IDF criteria and ethnicity-specific cut-off values of waist circumference can provide more useful information about the prevalence of MetS in China. Conclusion Using both the modified IDF criteria and ethnicity-specific cut-off values of waist circumference can provide more useful information about the prevalence of MetS in China.
