Background:Intrahepatic cholestasis is a commonly seen clinical manifestation, and often accompanied with jaundice.Study on clinical characteristics of patients with different degrees of jaundice is helpful for the acknowledge of intrahepatic cholestasis.Aims:To explore the clinical characteristics of intrahepatic cholestasis with jaundice.Methods:General data, biochemistry parameters, etiology and treatment of 703 patients with intrahepatic cholestasis were retrospectively analyzed.Results:Jaundice occurred in 168 patients (23.9%), including 149 mild jaundice, 15 moderate jaundice and 4 severe jaundice.Levels of ALT, AST, ALP, GGT, DBIL, TBIL, ratio of DBIL/TBIL, TBA were significantly increased in jaundice group than in non-jaundice group (P<0.05).Levels of ALT, AST, DBIL, TBIL, TBA were statistically different between groups with different degrees of jaundice (P<0.05), however, no significant differences in ALP, GGT, ratio of DBIL/TBIL were seen (P>0.05).The main etiology of intrahepatic cholestasis were digestive system tumors, cardiovascular diseases, shock, hematologic diseases and primary biliary cholangitis.Ursodeoxycholic acid and S-ademetionine were the main drugs for treatment of intrahepatic cholestasis.Conclusions:For patients with intrahepatic cholestasis, levels of ALT, AST, ALP, GGT are increased with the development of jaundice, and attention on damage of hepatocytes should be paid.The etiology of intrahepatic cholestasis with jaundice involves diseases of different organs and systems, most of them are malignant tumor, cardiovascular diseases, shock and primary biliary cholangitis.

Objective:To evaluate the effects of stellate ganglion block (SGB) on the activation of M1 microglia during cerebral ischemia-reperfusion (I/R) in rats.Methods:Fifty-four SPF healthy male Sprague-Dawley rats, aged 8-10 weeks, weighing 240-270 g, were divided into 3 groups ( n=18 each) using a random number table method: sham operation group (group Sham), cerebral I/R group (group IR) and SGB group.Blood vessels were only exposed, without occlusion in group Sham.Cerebral I/R was induced by occlusion of the middle cerebral artery for 90 min followed by reperfusion in group IR.Cervical sympathetic trunk transaction was performed to induce left SGB immediately after onset of reperfusion in group SGB.Blood samples were collected from the apex of the heart at 6, 12 and 24 h of reperfusion for determination of the concentrations of tumor necrosis factor (TNF)-α, interleukin (IL)-6, and IL-1β in the serum (using enzyme-linked immunosorbent assay). The animals were sacrificed after the neurological function was evaluated at 24 of reperfusion, and brain tissues were removed for microscopic examination of the pathological changes in cortex, for determination of percentage of cerebral infarct size (by TTC staining), for assessment of cell apoptosis and apoptosis rate in cortex (by TUNEL), and for determination of the expression of microglial biomarker Iba-1 and activated M1 microglia biomarker CD68 (by Western blot). Results:Compared with group Sham, the neurological function score, percentage cerebral infarct size, apoptosis rate in cortex, concentrations of TNF-α, IL-6 and IL-1β in the serum, and the expression of Iba-1 and CD68 were significantly increased in IR and SGB groups ( P<0.05). Compared with group IR, the neurological function score, percentage cerebral infarct size, apoptosis rate in cortex, concentrations of TNF-α, IL-6 and IL-1β in the serum, and the expression of Iba-1 and CD68 were significantly decreased in group SGB ( P<0.05), and the pathological changes of brain tissues were significantly attenuated in group SGB. Conclusion:The mechanism by which SGB reduces cerebral I/R injury is related to inhibiting activation of M1 microglia in rats.

BACKGROUND: It has been proved that interleukin-18 (IL-18) involves in the development of acute cerebral infarction (ACI) and is positively correlated with the time of brain stroke onset, erythrocyte sedimentation rate (ESR), as well as neurological deficit and low-density value of brain CT.OBJECTIVE: To investigate the dynamic changes of serum IL-18 in the course of ACI.DESIGN: Verification analysis with patients as subjects and healthy volunteers as controls.SETTING: Department of neurology of a municipal hospital.PARTICIPANTS: Totally 46 inpatients (29 males and 17 females) with ACI were randomly selected from the Department of Neurology of People's Hospital, Maoming City, between December 2002 and January 2004.Meanwhile, 40 healthy controls (27 males and 13 females) were recruited from those who came to the hospital for routine physical examination. All the participants signed informed consent.METHODS: Fasting peripheral vein blood of 2 mL was collected from the patients on the 1st, 7rh, 14th and 21st days of ACI onset, and from healthy controls on the day of routine examination. The blood samples were centrifuged at 3 000 r/minute for 15 minutes at 4 ℃, and then the supernatant was collected for detecting IL-18 level by ELISA.MAIN OUTCOME MEASURES: The serum IL-18 level of patients on the 1st, 7th 14th and 21st days of ACI onset and that of healthy controls on the day of routine examination.RFSULTS: Totally 46 patients and 40 healthy controls were enrolled in this study and all data were statistically analyzed. The level of serum IL-18 was significantly higher in the patients with ACI than in normal controls on the 1st and 7th days of onset [(178±41) ng/L, (104±34) ng/L, (65±14) ng/L, P ＜ 0.01],but was similar on the 14th and 21st days [(88±36) ng/L, (72±33) ng/L,(65±14) ng/L, P＞ 0.05]. The level of serum IL-18 in ACI patients was significantly higher on the 1st day than on the 7th, 14th and 21 st days of the onset (P ＜ 0.05-0.01); moreover, it was also significantly higher on the 7th day than on the 21st day of the onset (P ＜ 0.05).CONCLUSION: The level of IL-18 increases obviously on the 1st day of ACI onset, and gradually decreases with the extended course of disease and time of treatment.

Objective By investigating the obesity of the adult population in Hunan,we explored the relationship between body mass index (BMI) [including waist circumference (WC),waist-to-hip ratio (WHR),waist-to-body ratio (WHtR) and H-type hypertension] in predicting H-type hypertension.Methods A multi-stage random sampling method was used to conduct a questionnaire survey,physical examination and laboratory testing on 4 012 adults ＞ 30 years old in 6 districts of Hunan Province.The receiver operator characteristic (ROC) curve was used to evaluate the predictive effects of BMI,WC,WHR and WHtR on H-type hypertension.Results ROC curve analysis indicated that the area under curve (AUC) of the evaluation of H-type hypertension of WC,WHtR,WHR and BMI in men were:0.637,0.640,0.601,0.639,of which the largest were combination of WC + BMI and WHtR + BMI,both being 0.647.In women,the AUC of individual indexes WC,WHtR,WHR and BMI for evaluating H-type hypertension were 0.660,0.670,0.660 and 0.604 respectively.The combination of WHtR and WHR had the largest AUC,which was 0.675.The WC for evaluating H-type hypertension in youth people had the largest AUC (0.732);the WC + BMI,WHR + BMI for evaluating H-type hypertension in middle-aged people had the largest AUC,all being 0.687;the WC predicted the largest AUC of H-type hypertension in elderly people (0.590).Conclusions WC,WHtR,WHR and BMI are important predictors of H-type hypertension.The optimal indicators for different genders and ages are different,and the combined indicators are better than the individual indicators.

Objective To analyze the incidence and risk factors of postoperative esophageal stenosis after endoscopic submucosal dissection(ESD)with mucosal defect of 1/2?<3/4 circumference. Methods A retrospective analysis was performed on the data of 301 patients with early esophageal cancer or precancerous lesions undergoing ESD at Drum Tower Hospital between January 2013 and August 2015. The incidence and risk factors for postoperative stenosis were analyzed. Results Esophageal stenosis was observed in 13 cases among the 113 cases of 1/2?<3/4 circumference mucosal defect. The rate of stenosis was 11.5%. There was no significant difference between stenosis group and non?stenosis group in regard of gender, age, family history, concomitant diseases, lesion type, operation time, invasion depth, lesion longitudinal length,pathological diagnosis or complications after ESD(P>0.05),while the rate of lesions in the upper esophagus in stenosis group was higher than that in the control group(P<0.05). Conclusion Mucosal defect of 1/2?<3/4 circumference has a lower esophageal stenosis rate after ESD,which is related to the location of lesion. The ratio of upper esophagus lesion in the stenosis group is significantly higher than that in the non?stenosis group.

The authors introduced the development and application of an outpatient triage safety management system for hospitals. The system consists of the triage queue module, fast track module for prioritized special outpatients and subsequent outpatients, vital signs data recording module, assessment module for high fall risk outpatients, and high risk outpatient transfer module. These functions enable outpatient triage nurses to focus on pre-examination, safety factor identification, and high risk outpatient transfer, thus shortening outpatient queue time and high risk outpatient transfer to emergency, and lower adverse events. With this system, nursing safety management becomes more scientific, standardized and systematic, enabling optimized nursing staff efficiency and fine management of nursing care.

Objective To explore the value of prenatal ultrasound in diagnosis of omphalocele-exstrophy-imperforate anusspinal defects (OEIS) in first trimester.Methods Prenatal ultrasonic characteristics of 10 fetuses with OEIS complex in first trimester were retrospectively analyzed and compared with autopsy results.Results Cystic bulging in the lower anterior abdominal wall was observed in all 10 fetuses.Spinal scoliosis dysplasia was found in 10 fetuses,with myelomeningocele in 3 fetuses.No normal bladder was visualized in 8 fetuses.Thickened nuchal translucency was noticed in 5 fetuses,among which neck lymphatic hydrocele was found in 1 fetus.The bilateral clubbed feet and left lower mutilation was observed in 1 fetus,respectively.All 10 OEIS complex fetuses were found accompanied with short umbilical cord,while single umbilical artery and umbilical cord cyst were found in 4 and 1 fetus,respectively.Autopsy showed abdominal wall defects with exstrophy in 10 fetuses.However,no complete cystic bulging was found.Besides,autopsy also showed pubic symphysis separation and bladder exstrophy in 10 fetuses without obvious genitalia nor anus.Conclusion Cystic bulging in the lower anterior abdominal wall is the most common prenatal ultrasonic characteristic of OEIS complex in first trimester.
