Objective To explore the clinical value of serum interleukin(IL)-33 and its soluble receptor ST2(sST2) level in patients with chronic hepatitis B.Methods A total of 65 cases with chronic hepatitis B were recruited into study group,meanwhile 60 healthy persons were enrolled in the control group from January 2014 to October 2016 in our hospital.IL-33,sST2 and alanine aminotransferase(ALT) were detected and compared in the two groups.Results The level of IL-33,sST2 and ALT were significant higher than those of the control group(t=6.542,7.218,6.324;P<0.05).IL-33 and sST2 levels in chronic hepatitis B patients with abnormal ALT level were significant higher than those with normal ALT(t=16.328,9.874,P<0.05).Conclusion The detection of IL-33 and sST2 in patients with chronic hepatitis B could help to understand the immune status of patients,and provide a theoretical basis for the treatment of chronic hepatitis B.

Objective To investigate the relationship between serum uric acid (UA) level and abdominal obesity or metabolic syndrome (MS).Methods A total of 875 subjects,with 350 males and 525 females,aged 40-65 years old,were enrolled in this study.The clinical and biochemical data were collected and MRI was used to assess the visceral and subcutaneous adipose tissues.The relationships between UA level and abdominal obesity or MS were analyzed,and the cut-off values of UA for abdominal obesity and MS were determined.Results Raised risks of abdominal obesity (OR =4.35,95％ CI 1.91-9.90 in males; OR =5.44,95％ CI 2.41-12.31 in females) and MS (OR =4.47,95 ％ CI 2.08-9.62 in males; OR =11.62,95％ CI 3.43-39.37 in females) were observed with the increase of UA level.The multiple logistic regression analysis showed that UA was an independent risk factor for hypertriglyceridemia (OR =2.23,95％ CI 1.02-4.87 in males ; OR =3.04,95％ CI 1.49-6.23 in females) in all subjects and for abdominal obesity(OR =3.23,95％ CI 1.32-7.91) and hypertension (OR =2.35,95％ CI 1.37-4.05)in the females.Among the females,the regression line analyzed by simple correlation indicated that the UA level of 244.0 μmol/L was corresponded to the visceral adipose tissue area of 80 cm2.The optimal cut-off point of UA for the diagnosis of MS was 258.8 μmol/L determined by the receiver operating characteristic curve.Conclusions The level of UA is closely correlated with abdominal obesity and MS in the middleaged Chinese.The elevated UA level is an independent risk factor for abdominal obesity and MS in the female.

Background Laser in situ keratomileusis (LASIK) is widely applicated to correct the refractive error in ophthalmology nowadays.However,the morphology and structure changes of anterior eye segment caused by the ablation of corneal stroma and suction of negative pressure during surgery should be concerned.Objective This study was to assess the changes of the anterior eye segment parameters and the factors influencing these parameters after LASIK.Methods The clinical data of 59 eyes of 31 patients who received LASIK in Chongqing Medal Eye Institute during May 2012 to July 2013 were retrospectively analyzed.The mean age of the patients was (24.52±8.41) years and the spherical equivalent was (-5.96±3.75) D.The central anterior chamber angle (ACA),anterior chamber volume (ACV),anterior chamber depth (ACD) were measured with Sirius Scheimpflug tomography,and lens thickness (LT) was measured by A-scan before operation and 1,3,6 months after operation.The anterior chamber was divided into anterior and posterior parts by the plane of cornea 4 mm radius area.The ACD of cornea 4 mm radius area sagittal height section (Sag4mm ACD) (the height from posterior corneal vertex to corneal radius of 4 mm plane) and residual ACD (RACD) (the height from corneal radius of 4 mm plane to the anterior lens surface) were computed.The association between ACD and RACD or LT were assessed by Pearson correlation analysis.Results The ACA,ACV,ACD,RACD and LT were significantly different among various time points before and after LASIK (F =8.319,P＜0.05;F =11.596,P＜0.05;F =24.045,P＜0.01;F =16.087,P＜0.05;F =15.333,P＜0.01),and the ACA,ACV,ACD and RACD were significantly decreased 1-6 months after LASIK than those before LASIK (all at P＜0.05).There were no significant differences in the Sag4 mm ACD between pre-and postLASIK (all at P＞0.05).The LT was significantly increased after surgery in comparison with that before surgery (P＜0.01).The positive correlations were found between RACD and ACD before LASIK and in 1,3,6 months after LASIK (r =0.976,0.824,0.724,0.938,all at P＜0.05) and negative correlation between LT and ACD in 3 and 6 months after LASIK (r=-0.344,P＜0.01;r =-0.363,P＜0.01).Conclusions The ACD decrease following LASIK mainly in the sector from the plane of cornea 4 mm radius area to lens surface.The change of ACD might be associated with forward shifting of anterior lens surface caused by enhanced accommodation.

OBJECTIVETo investigate whether the angiotensin II type I receptor gene (AGTR1) A1166C polymorphism is associated with a high risk of diabetic nephropathy.

METHODSThe allele frequency and the genotype distribution of the AGTR1 A1166C polymorphism were studied in normal controls (157 cases), simple diabetes (141 cases, duration of diabetes >10 years), and diabetic nephropathy (152 cases) by means of polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP).

RESULTSPatients with diabetic nephropathy had a higher frequency of C allele of the AGTR1 A1166C polymorphism than that of normal controls and simple diabetes (P<0.05); but there was no significant difference in frequency of C allele between the normal controls and patients with simple diabetes.

CONCLUSIONThe diabetic patients with AGTR1 C allele may be more susceptible to diabetic nephropathy than diabetic patients with A allele.

Objective To investigate the relationship between ischemic time and thrombus types in patients with ST-segment elevation myocardial infarction (STEMI).Methods Eighty-two STEMI patients undergone emergency percutaneous coronary intervention (PCI) and coronary thrombus aspiration (CTA) from Sep.2012 to Apr.2016 were included and divided into 3 groups according to the ischemic time:≤4 hours (n=36),4-7 hours (n=30) and ＞7 hours (n=16).Visible aspirated thrombi were collected and separated into erythrocyte-rich type,platelet/fibrin-rich type and combined type thrombi by HE dying.The percentage difference of the 3 types thrombi was compared among the 3 groups.Results The percentage of platelet/fibrinrich type,erythrocyte-rich type and combined type thrombi in the 3 groups were as follows:in ≤4h group:61.1％(22/36),8.3％(3/36) and 30.6％(11/36),P=0.019;in 4-7h group:23.3％(7/30),10.0％(3/30) and 66.7％(20/30),P=0.012;and in ＞7h group:43.8％(7/16),12.5％(2/16) and 43.8％(7/16),P=0.913.For platelet/fibrin-rich type thrombi,the percentages in 3 periods were 61.1％(22/36),19.4％(7/36) and 19.4％(7/36),P=0.009;For combined type thrombi,the percentages in 3 periods were 28.9％(11/38),52.6％(20/38) and 18.4％(7/38),P=0.013;For erythrocyte-rich type thrombi,the percentages in 3 periods were 37.5％(3/8),37.5％(3/8) and 25.0％(2/8),P=0.895.Conclusions The types of intracoronary aspirated thrombi differ from various periods.Ischemia time may be an important predicted factor.

Objective:To evaluate the development of hypothermia after spinal anesthesia and risk factors.Methods:Patients undergoing spinal anesthesia in the anesthesia preparation room of our hospital from April 2020 to April 2021 were included. The temperature of the tympanic membrane was measured before spinal anesthesia and immediately after anesthesia and at 5, 10 and 15 min after anesthesia. Patients with tympanic membrane temperature<36 ℃ at any time point were considered as having hypothermia and included in hypothermia group and patients with membrane temperature ≥ 36 ℃ were considered as having no hypothermia and included in non-hypothermia group. The patients′ demographic data, highest anesthesia plane, puncture space of spinal anesthesia, types of anesthetics, preoperative fasting time, and surgical sites were recorded. The multivariate logistic regression analysis was performed to identify the risk factors for hypothermia.Results:A total of 196 patients were finally enrolled. The body temperature was significantly decreased at 5 and 10 min after anesthesia compared with the baseline body temperature before anesthesia and immediately after anesthesia ( P<0.001), and the incidence of hypothermia was 10.2%. The multivariate logistic regression analysis showed that female and high anesthesia plane were independent risk factors for hypothermia, and higher baseline body temperature was an independent protective factor for hypothermia ( P<0.05). Conclusions:Body temperature decreases at 5-10 min after spinal anesthesia, and the occurrence of hypothermia is not a small probability event in the patients undergoing spinal anesthesia; female and higher anesthesia plane are risk factors and higher baseline body temperature is the protective factor.

Objective To study the relationship between the abnormal blood fat components and the serum hypersensitivity C reaction protein concentration and the progression of diabetic retinopathy.Methods Fundus examination was carried out to inpatients in the Department of Endocrinology in the hospital from From July 2015to July 2017.These patients were divided into three groups according to results of fluorescein sodium contrast:The non retinopathy group (group A) , the non proliferative retinopathy group (group B) , the retinopathy proliferative phase group (group C) .The content of blood fat component and serum hypersensitivity C reaction protein in the experimental cases were measured, and the ratio of TC/HDL-C was calculated.The statistic software of SAS9.4was used for statistical processing.Results The concentration of the serum hypersensitive C reaction protein in patients with diabetic retinopathy was significantly increased and the ratio of TC/HDL-C increased significantly (P<0.05) .The hs-CRP concentration and TC/HDL-C ratio of the three study groups were compared with those of the healthy control group:the difference was statistically significant (P<0.05) .Among them, the hs-CRP concentration and TC/HDL-C ratio of group A were compared with group B and group C respectively and the difference were statistically significant (P<0.05) .There was no significant difference in hs-CRP concentration and TC/HDL-C ratio between group B and group C (P>0.05) .Linear correlation analysis was used to analyze the concentration of serum hypersensitive C reaction protein and the ratio of TC/HDL-C.It was found that there was a positive correlation between them, and there was a positive synergistic effect.Conclusion The measurement of serum hypersensitive C reactive protein has important clinical value for the discovery, evaluation and prognosis of diabetic retinopathy.The abnormalities of the blood fat component reflected by the TC/HDL ratio are also an important factor in assessing the progression of diabetic retinopathy.

Objective:To evaluate the clinical effect of the position pillows for neuraxial anesthesia.Methods:This was a prospective randomized controlled trial. Four hundred and twelve patients regardless of gender, aged ≥18 yr, of American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅲ, who underwent elective surgery under neuraxial anesthesia at Peking University Third Hospital from February to October 2023, were selected and divided into 2 groups ( n=206 each) using a random number table method: pillow group (P group) and control group (C group). Group C underwent the conventional procedure for neuraxial anesthesia. The patients were placed in a position using the position pillow on the basis of oral education before routine anesthesia in group P. The success rate of puncture at first attempt, puncture time and position placement time were recorded. The adjustment of position, body movement and occurrence of discomfort during the puncture were also recorded. The visual analogue scale score was used to evaluate the level of anxiety before positioning, after positioning and after anesthesia. The visual analogue scale score was used to evaluate the patient′s comfort and the operator′s satisfaction with position after the anesthesia was completed. Results:Compared with group C, the time for positioning was significantly shortened, the anxiety level was decreased after positioning and after anesthesia, the rate of improvement in anxiety was increased, the scores for the patient′s comfort and the operator′s satisfaction with position were increased ( P<0.05), and no significant changes were found in the success rate of puncture at first attempt, puncture time and incidence of body movement during the puncture and incidence of the adjustment of position ( P>0.05). No discomfort was observed in either group during the puncture. Conclusions:This new type of position pillows for the neuraxial anesthesia can not only optimize the effect of position placement, but also improve the patients′ comfort.

Objective:To explore the associations of urinary retinol binding protein (RBP) and β 2-microglobulin (β 2-MG) with urinary albumin to creatinine ratio (UACR) and renal function in hospitalized patients with type 2 diabetes mellitus (T2DM). Methods:A total of 1 030 Chinese patients with T2DM were included in this study. The subjects were divided into the UACR normal group (<30 mg/g), microalbuminuria group (30-300 mg/g) and macroalbuminuria group (>300 mg/g). Patients with normal UACR were further divided into two groups according to the estimated glomerular filtration rate (eGFR): the eGFR low group (<90 ml·min -1·1.73m -2) and the normal eGFR group (≥90 ml·min -1·1.73m -2). Urine RBP and β 2-MG levels among the groups were compared. Multiple linear regression analyses were applied to evaluate risk factors of urine RBP and β 2-MG. Results:In all patients ( n=1 030), urine RBP and β 2-MG increased gradually with the increase of UACR across the three groups, the proportions of abnormal urine RBP (>0.7 mg/L) and β 2-MG (>370 μg/L) in these groups were 3.8%, 8.5%, 39.0% ( P<0.001), and 12.9%, 26.7%, 46.8% ( P<0.001), respectively. In the UACR normal group ( n=788), 12.2% of the patients were with eGFR<90 ml·min -1·1.73m -2. The proportion of abnormal β 2-MG (>370 μg/L) was higher in the eGFR low group than that in the eGFR normal group (29.2% vs. 10.7%, P<0.001). Multivariate linear stepwise regression analyses were performed using natural logarithm of urine RBP or β 2-MG as dependent variable, and showed that urine RBP was independently associated with UACR ( β=0.0005, P<0.001), serum creatinine ( β=0.006, P<0.001) and glycosylated hemoglobin A1c ( β=0.050, P=0.001), and β 2-MG was independently correlated with UACR ( β=0.000 4, P<0.001), serum creatinine ( β=0.011, P<0.001), systolic blood pressure ( β=0.005, P=0.031) and fasting blood-glucose ( β=0.027, P=0.046). Conclusions:Urine RBP and β 2-MG are positively associated with high UACR and impaired renal function in T2DM patients, and these changes could occur before UACR and eGFR turned out to be abnormal. It is recommended that urine RBP and β 2-MG be detected as early as possible to identify diabetic kidney disease in patients with normal UACR and eGFR.
