Objective To detect the levels of IL-1, IL-6,TNF-αand IFN-γin serum and colon tissue of rat mod-els of ulcerative colitis with spleen and kidney Yang deficiency, and to explore their roles in the pathogenesis of ulcerative colitis ( UC) .Methods The rat model of ulcerative colitis with Yang deficiency of spleen and kidney was induced by perfusion of rhubarb decoction plus intramuscular injection of hydrocortisone and combined with TNBS (2,4,6-trinitro-benzenesulfonic acid) and ethanol enema.Sixty SPF wistar rats ( body weight 180 ±10 g, male:female=1:1) were ran-domly divided into blank control group, UC model with spleen kidney Yang deficiency for 7 days, 14 days and 21 days groups, respectively.The levels of IL-1, IL-6, TNF-αand IFN-γin serum and colon tissue were detected by ELISA.Re-sults Compared with the blank group, the levels of IL-1, IL-6, TNF-αand IFN-γin serum and colon tissue of rat UC model group with spleen kidney Yang deficiency were greatly increased (P<0.05), especially evidently increased in the model group at 21 days.Conclusions The pro-inflammatory cytokines IL-1, IL-6, TNF-αand IFN-γplay an important role in the pathogenesis of ulcerative colitis with syndrome of spleen and kidney Yang deficiency.

Objective:To prepare a pig model of obstructive sleep apnea-hypopnea syndrome(OSAHS) and to observe the hemodynamics and pathological characteristics of common carotid artery,so as to lay a foundation for further studying the effect of OSAHS on cardiovascular system.Methods: Twelve male small-type pigs were randomly divided into model group and control group(n=6).Animals in the model group were housed in a negative pressure chamber for 6 months to establish OSAHS model and those in the normal control group were fed routinely.After pigs in the model group presented the symptoms of OSAHS,the changes in hemodynamics of carotid artery were detected with color Doppler ultrasound.The morphological changes of common carotid artery were analyzed under light microscope and electron microscope.Results: Animal model of OSAHS was successfully created.The internal diameter of carotid artery of pigs in the model group was decreased,the intima was increased,and the peak-systolic mean velocity(S) and the resistance index(RI) were both increased compared with those of the control group(P

Objective To explore the relationship between traditional Chinese medicine (TCM) syndromes of state of evil domination and clinical and laboratory indicators of IgA nephropathy. Methods A prospective study was used to collect data on clinical and laboratory examination of IgA nephropathy in multi clinical centers. Patients’ TCM syndrome types were determined according to the national diagnostic criteria at the same time. Totally 266 patients with IgA nephropathy were included in the study to establish a database for analyzing the relationship between TCM syndrome of state of evil domination and clinical and laboratory indicators. Results In the relationship between syndromes of state of evil domination distribution and clinical subtypes, patients of wind-heat syndrome had more macroscopic hematuria;patients of phlegm-damp syndrome had more nephrotic syndrome;patients of damp-heat syndrome had more chronic nephritis type Ⅰ;patients of blood stasis syndrome had more chronic nephritis type Ⅱ. In the relationship between syndrome of state of evil domination distribution and clinical manifestation, the incidence of hypertension was higher in patients of blood stasis syndrome than in other three types. It was more serious for hematuresis in the patients of wind-heat syndrome. For patients of phlegm-damp syndrome, the incidence of heave proteinuria was highest. In the relationship between syndrome of state of evil domination distribution and laboratory examination, 24-hour urinary protein quantification was higher than in patients of wind-heat and damp-heat syndrome, but the level of blood albumin was lowest. For patients of blood stasis syndrome, serum creatinine level was significantly higher than in other three types;the level of eGFR was just the opposite. The levels of blood cholesterol and triglyceride in patients of phlegm-damp syndrome were higher than in other three types. The activated partial thromboplastin time (APTT) levels in patients of blood stasis and phlegm-damp syndrome were lower than in other patients, but the FIB level was the exact opposite of APTT. In the relationship between syndrome of state of evil domination distribution and the stages of chronic kidney disease (CKD), patients of wind-heat syndrome were more in the first stage of CKD;patients of blood stasis syndrome were more in the third stage of CKD. Conclusion There is relative correlation between TCM syndromes of state of evil domination and clinical and laboratory indicators in IgA nephropathy, which would provide some reference to narrow the gap in the information of the four methods of TCM with clinical and laboratory indicators to enhance accurate diagnosis of TCM syndrome.

Objective: To explore the emotional and behavioral problems of different only child and multiple child families, and to provide a reference for developing effective parenting styles. Methods: A stratified random cluster sampling method was adopted to investigate 2 647 guardians of preschool children in Tongling City from April to June, 2022. Children s emotional and behavioral problems were evaluated by using the self designed parenting questionnaire and the Children s Strengths and Difficulties Questionnaire (SDQ) parent edition. Results: The abnormal total score detection rate of emotional and behavioral problems of preschool children was 15.5%, and the rate of abnormal peer interaction was the highest (19.5%). In multiple child families, the first born child (17.5%, 20.4%), compared with the second and third child (11.5%, 9.5%), was more likely to exhibit conduct and hyperactivity problems ( χ 2=8.44, 29.75, P <0.01). There were differences in parenting attitudes between only child and multiple child families( χ 2=9.38, P <0.05). The results of the Logistic regression analysis showed that more frequent parent child discussion, the persuasive education and consistent family discipline strategy were negatively related to the emotional and behavioral problems of only children and children in multiple child families ( OR =0.15, 0.49, 0.38; 0.34, 0.40, 0.42, P <0.05). However, harmonious family relationships were only negatively related to emotional and behavioral problems in only children ( OR =0.08, P <0.01), and a higher education level among mothers was negatively related to emotional and behavioral problems in children from multiple child family environments( OR=0.30, 0.45, P <0.05). Conclusion The emotional and behavioral problems are serious of preschool children in Tongling City, the psychological development of the oldest children from multiple child and only child families should be actively followed, as this would help to promote a better understanding of the development of preschool children s physical and mental health.

Objective: To examine the eating behaviors and associated factors among preschool children from multiple child families, so as to provide a basis for promoting healthy eating habits in this population. Methods: From April to June 2022, a stratified random cluster sampling method was employed to selected 2 647 guardians of preschool children in 11 kindergartens in Tongling City. Parenting style questionnaire, Identification and Management of Feeding Difficulty Questionnaire (IMFeD), Caregiver s Feeding Style Questionnaire (CFSQ) and a self designed questionnaire were administered. Multiple linear regression was performed to analyze the factors influencing eating behaviors among preschool children. Results: In the study, the detection of eating behavior problems among preschool children was 71.4%, and the detection of reduced appetite was the highest (55.6%). The detection rates of anorexia, picky eating, poor eating and improper eating behavior in only child families were higher (60.6%, 41.0%, 32.0%, 19.5%), compared with those in multiple child families (51.7%, 36.4%, 27.2%, 16.6%) ( χ 2=20.05, 5.95, 7.16, 3.92, P < 0.05 ). Among multiple child families, the detection rates of fear of eating and underlying disease were the lowest in 5-<10-year-old group (2.3%, 0.6%) ( χ 2=11.54, 8.51, P <0.05). In multiple child families, the detection rates of picky eating and poor eating habits for the first-born child were higher (42.0%, 32.5%), compared with second born and third born child (34.6%, 25.6%)( χ 2= 6.15, 6.38, P <0.05). The results of multiple linear regression analysis showed that multiplechild families ( β =-1.40), democratic parenting style ( β =-0.07), higher feeding response scores ( β =-0.33) were negatively associated with eating behavior problems among preschool children ( P <0.05). Eating behavior problems among preschool children were positively correlated with less educated mothers [high and junior high school education ( β =0.87), primary school education and below ( β =3.69)], longer average daily screen time ( β =0.10), higher feeding requirements scores ( β =0.64), doting parenting styles ( β =0.21), permissive parenting styles ( β =0.27) and inconsistent parenting styles ( β =0.14)( P <0.05). Conclusion The detection rate of the eating behaviors problems among preschool children is high in schools. Greater attention should be paid to only child and first born child of multiple child families, and appropriate feeding and parenting styles, so as to promote healthy eating habits among this population.

Objective To investigate the prevalence of complication and related risk factors in Uygur patients with type 2 diabetes mellitus (T2DM).Methods Total 1 507 Uygur patients aged above 20 with T2DM were recruited in the First Affiliated Hospital of Xinjiang Medical University from January 2010 to October 2015.Clinical characteristics,biochemical parameters and related complications were analyzed in different age groups of patients.Multivariate logistic regression was performed to determine associated factors for diabetic complications.Results Among 1 507 cases,there were 61.3％ male patients (n=924),37.4％ (n=564) with diabetes duration ≥5 years,12.5％ (n=189) with HbA1c＞10％,31.5％ (n=475) with hypertension,28.8％ (n=434) with smoking history and 37.4％ (n=564) patients without antidiabetic drug treatment.The average body mass index (BMI) of patients was (27.4±5.2)kg/m2 with a obesity rate of 43.0％ (648/1 507),and 65.0％ (980/1 507) had physical exercise＜150 min/week.The prevalence of diabetic complication was 70.6％(1 064/1 507),in which 28.7％,19.2％ and 22.7％ cases had 1,2 and 3 or more complications,respectively.The proportion of patients with coronary heart disease,stroke/transient ischemic attack and large artery atherosclerosis was 32.4％,10.4％ and 35.8％,respectively.The proportion of patients with diabetic retinopathy,nephropathy and neuropathy were 23.4％,6.5％ and 35.8％,respectively.Patients aged ≥60 years had highest prevalence of large artery atherosclerosis (38.2％,163/427) and diabetic retinopathy (27.2％,116/427);patients in age group 50-59 years had highest prevalence of diabetic neuropathy (40.3％,207/514).Multivariate logistic regression analysis showed that HbA1c＞10％ (OR=2.74,95％CI:1.40-5.34),obesity (OR=1.54,95％CI:1.07-2.21),systolic pressure≥140 mmHg (1 mmHg=0.133 kPa) (OR=1.42,95％CI:1.01-1.99),diastolic pressure≥90 mmHg (OR=0.37,95％CI:0.21-0.67),smoking (OR=1.53,95％CI:1.09-2.15) and physical aetivity＜150 min/week (OR=1.42,95％CI:1.07-1.89) were the risk factors of diabetic complications.Conclusion Uygur patients with type 2 diabetes in Xinjiang show a relatively high prevalence of complications.Poor glycemic control,obesity,hypertension,smoking and physical inactivity may contribute to development of complications,while well-controlled blood glucose and hypertension and quitting smoking and increasing physical activity may reduce diabetic complications.

OBJECTIVE: To observe the correlation between early fluid resuscitation and prognosis in patients with severe acute pancreatitis (SAP). METHODS: SAP patients admitted to the department of critical care medicine of the People's Hospital of Chuxiong Yi Autonomous Prefecture of Yunnan Province from June 2018 to December 2020 were enrolled and analyzed retrospectively. All patients were given the routine treatment according to their condition and relevant diagnostic According to their different prognosis, enrolled patients were divided into death group and survival group. The differences in gender, age, acute physiology and chronic health evaluation II (APACHE II) and Ranson score on admission between the two groups were analyzed. Taking 24 hours as an observation day, the fluid inflow, outflow, and net balance at the first, second, and third 24 hours after admission were recorded, and the ratio of the fluid inflow at the first 24 hours to the total fluid inflow in 72 hours (FV_{24 h-1 st}) was calculated as a study index. Using 33% as the standard, compare the proportion of patients in the two groups who achieved FV_{24 h-1 st} < 33%. The differences of various indicators between the two groups were compared, and the effect of early fluid balance on the prognosis of SAP patients was analyzed. RESULTS: Eighty-nine patients were included in the study (41 in the death group, 48 in the survival group). There were no statistically significant differences on age (years old: 57.6±15.2 vs. 49.5±15.2), gender (male: 61.0% vs. 54.2%), APACHE II score (18.0±2.4 vs. 17.3±2.3), and Ranson score (6.3±1.4 vs. 5.9±1.2) between the death group and the survival group at the time of admission on the intensive care unit (ICU) (all P > 0.05). The fluid intake of the death group in the first 24 hours, the second 24 hours and the third 24 hours after admission to ICU was significantly higher than that of the survival group, and the difference was statistically significant (mL: 4 138±832 vs. 3 535±1 058, 3 883±729 vs. 3 324±516, 3 786±490 vs. 3 212±609, all P < 0.05), and the fluid inflow in the death group at the first 24 hours was greater than 4 100 mL. After treatment, the fluid outflow of the death group at the three 24-hour periods after admission on the ICU was an increasing trend, but it was still significantly less than that of the survival group at the three 24-hour periods (mL: 1 242±465 vs. 1 795±819, 1 536±579 vs. 2 080±524, 1 610±585 vs. 2 932±752, all P < 0.01). Due to the fact that the total fluid inflow and total fluid outflow in the three 24-hour periods in the death group were more than those in the survival group, the net fluid balances in the three 24-hour periods in the death group were still significantly more than those in the survival group finally (mL: 2 896±782 vs. 1 740±725, 2 347±459 vs. 1 243±795, 2 176±807 vs. 338±289, all P < 0.01). There was no difference in FV_{24 h-1 st} between the death group and survival group [FV_{24 h-1 st} > 33%: 56.1% (23/41) vs. 54.2% (26/48), P > 0.05]. CONCLUSIONS Fluid resuscitation is an important method for early treatment of SAP, but it also has many adverse reactions. Fluid resuscitation indexes such as fluid inflow, outflow, net balance, and FV_{24 h-1 st} within 24 to 72 hours after admission are related to the prognosis of patients with SAP, and can be used as indicators to evaluate the prognosis of SAP. The optimized fluid resuscitation strategy can improve the prognosis of patients with SAP.
