ABSTRACT
Objective:To explore the efficacy of the combination of radiofrequency ablation(RFA) and endoscopic metal stent in the treatment of patients with unresectable cholangiocarcinoma.Methods:From January 3, 2012 to June 30, 2019, at the Department of Endoscopic of the Third Affiliated Hospital of Naval Medical University, the clinical data of 44 patients with unresectable cholangiocarcinoma who were treated by the combination of RFA and endoscopic metal stent were retrospectively collected, which included age, gender, location of cholangiocarcinoma(hilar cholangiocarcinoma and distal cholangiocarcinoma), etc. Postoperative evaluation was conducted based on the follow-up, including clinical success rate, postoperative complication rate, time of stent patency and overall survival time (OS). The Kaplan-Meier method and log-rank test were used to analyze the difference of OS between patients with hilar cholangiocarcinoma and distal cholangiocarcinoma. Mann-Whitney U test was used for statistical analysis. Results:The age of the 44 patients with cholangiocarcinoma was (70.3±11.6) years old, with 20 males (45.5%). There were 22 patients (50.0%) with hilar cholangiocarcinoma and 22 patients (50.0%) with distal cholangiocarcinoma. The clinical success rate of 44 patients was 93.2%(41/44). A total of 5 patients(11.4%) had postoperative complications, which were all improved by appropriate treatment. The median time of follow-up of the 44 patient was 9.2 months(ranged from 3.1 to 57.6 months), the median time of stent patency was 7.0 months (ranged from 5.8 to 8.2 months). Thirty-two patients (72.7%) died during the follow-up, and the median OS was 10.9 months(ranged from 9.0 to 12.8 months). The median OS of patients with hilar cholangiocarcinoma was 7.8 months(ranged from 4.6 to 11.0 months) and that of patients with distal cholangiocarcinoma was 12.5 months(ranged from 5.7 to 19.4 months), and there was no statistically significant difference( P>0.05). Conclusion:RFA combined with endoscopic metal stent is safe and effective in the treatment of patients with unresectable cholangiocarcinoma.
ABSTRACT
Objective:To investigate the influence of liver drainage volume on overall survival time in patients with unresectable malignant hilar bile duct obstruction.Methods:Data of 633 patients with unresectable malignant hilar bile duct obstruction (BismuthⅡ-Ⅳ) who underwent endoscopic stent drainage in 3 endoscopy centers from January 2002 to May 2019 were retrospectively analyzed. Main observation indicators included clinical success rate, stent patency, overall survival, the effective liver drainage volume, and complication incidence.Results:The clinical success rates of patients with liver drainage volume <30%, 30%-50%, and >50% were 56.8% (25/44), 77.3% (201/260) and 84.2% (277/329) respectively. The incidences of early cholangitis were 31.8% (14/44), 18.8% (49/260) and 16.1% (53/329). The median stent patency time was 4.5 (95% CI: 1.8-7.2) months, 5.6 (95% CI: 5.0-6.2) months and 6.6 (95% CI: 5.2-8.0) months. The overall survival time was 2.4 (95% CI: 1.8-3.0) months, 4.0 (95% CI: 3.4-4.6) months and 4.9 (95% CI:4.4-5.4) months, respectively. The clinical success rate ( χ 2=8.28, P=0.012), median stent patency period ( χ 2=18.87, P=0.015) and overall survival time ( χ 2=6.93, P=0.024) of 30%-50% liver drainage volume group were significantly higher than those of <30% group. Further multivariate cox regression analysis showed that the disease type (hepatocellular carcinoma VS hilar cholangiocarcinoma: HR=1.50, 95% CI:1.18-1.91, P=0.001; gallbladder carcinoma VS hilar cholangiocarcinoma: HR=1.45, 95% CI:1.14-1.85, P=0.002; metastatic cholangiocarcinoma VS hilar cholangiocarcinoma: HR=1.48, 95% CI:1.08-2.04, P=0.015), bilirubin level >200 μmol/L ( HR=1.35, 95% CI:1.14-1.60, P<0.001),metal stents ( HR=0.67, 95% CI:0.56-0.79, P<0.001), liver drainage volume (volume 30%-50% VS <30%: HR=0.64, 95% CI: 0.45-0.90, P=0.010; volume>50% VS <30%: HR=0.58, 95% CI:0.41-0.81, P=0.002) and anti-tumor therapy ( HR=0.51, 95% CI:0.42-0.61, P<0.001) were independent predictors for overall survival time of patients with unresectable malignant hilar bile duct obstruction. Conclusion:When endoscopic stent drainage is performed for patients with unresectable malignant hilar bile duct obstruction, at least 30% liver volume is required for better overall survival. In addition, the use of metal stent drainage and anti-tumor therapy may increase survival benefits.
ABSTRACT
Objective:To investigate the application value of different metal stents place-ment position in endoscopic drainage of malignant hilar bile duct obstruction.Methods:The retro-spective cohort study was conducted. The clinicopathological data of 300 patients with malignant hilar bile duct obstruction who were admitted to 3 medical centers, including 216 patients in the Third Affiliated Hospital of Naval Medical University, 48 patients in the Xijing Hospital of Air Force Medical University, 36 patients in the First People's Hospital Affiliated to Shanghai Jiaotong University School of Medicine, from January 2012 to January 2019 were collected. There were 164 males and 136 females, aged (67±12)years. All patients were determined to be unresectable by multidisciplinary consultation and underwent endoscopic retrograde cholangiopancreatography. Observation indicators: (1) clinicopathological features of patients; (2) follow-up; (3) analysis of influencing factors for patency time of metal biliary stents and overall survival time of patients. Follow-up was conducted using outpatient examination and telephone interview to detect patency of metal biliary stents and survival of patients up to July 2019 or death of patients. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the Mann-Whitney U test. Count data were expressed as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data was conducted using the rank sum test. Kaplan-Meier method was used to calculate survival rates and draw survival curves, and Log-Rank test was used to conduct survival analysis. COX regression model was used for univariate and multivariate analyses. Factors with P<0.1 in univariate analysis were included in multivariate analysis. Results:(1) Clinicopathological features of patients. Of the 300 patients, 163 cases underwent endoscopic drainage with at least one metal biliary stent' distal portion crossing the duodenal main papilla (hereinafter referred to as crossing papilla), and 137 cases underwent endoscopic drainage with no metal biliary stent' distal portion crossing the duodenal main papilla (hereinafter referred to as no crossing papilla). Age, disease type (hilar cholangiocarcinoma, hepatocellular carcinoma, intrahepatic cholangio-carcinoma, gallbladder carcinoma, metastatic cholangiocarcinoma), metal biliary stents type (unilateral metal biliary stent, bilateral metal biliary stents) of patients with crossing papilla were (68±13)years, 95, 8, 11, 31, 18, 63, 100, respectively. The above indicators of patients with no crossing papilla were (64±12)years, 63, 22, 20, 23, 9, 126, 11, respectively. There were significant differences in the above indicators between patients with crossing papilla and patients with no crossing papilla ( t=2.70, χ2=17.69, 90.79, P<0.05). (2) Follow-up. All the 300 patients were followed up for 5.4(3.1,9.3)months. The patency time of metal biliary stents was 9.0(8.2,9.8)months and 6.4(4.8,8.0)months of patients with crossing papilla and patients with no crossing papilla, showing a significant difference between them ( χ2=8.23, P<0.05). The overall survival time was 5.5(4.2,6.8)months and 5.5(4.3,6.8)months of patients with crossing papilla and patients with no crossing papilla, showing no significant difference between them ( χ2=0.28, P>0.05). (3) Analysis of influencing factors for patency time of metal biliary stents and overall survival time of patients. Results of univariate analysis showed that type of metal biliary stents and the placement position of metal biliary stents were related factors affecting the patency time of metal biliary stents [ hazard ratio( HR)=0.44, 0.60, 95% confidence intervals as 0.30?0.64, 0.42?0.85, P<0.05]. Results of multi-variate analysis showed that bilateral metal biliary stents was an independent protective factor for the patency time of metal biliary stents ( HR=0.46, 95% confidence interval as 0.29?0.72, P<0.05). Results of univariate analysis showed that disease type (intrahepatic cholangiocarcinoma versus hilar cholangiocarcinoma), preoperative serum total bilirubin, type of metal biliary stents, anti-tumor therapy were related factors affecting the overall survival time of patients ( HR=1.05, 1.43, 0.72, 0.61, 95% confidence intervals as 0.70?1.57, 1.12?1.83, 0.55?0.92, 0.47?0.81, P<0.05). Results of multi-variate analysis showed that age >60 years, disease type as hepatocellular carcinoma, preoperative serum total bilirubin >200 μmol/L were independent risk factors for the overall survival time of patients ( HR=1.35, 1.98, 1.46, 95% confidence intervals as 1.02?1.79, 1.40?2.80, 1.13?1.89, P<0.05), and bilateral metal biliary stents, anti-tumor therapy were independent protective factors for the overall survival time of patients ( HR=0.68, 0.60, 95% confidence intervals as 0.53?0.89, 0.45?0.80, P<0.05). Conclusions:Endoscopic drainage with or without metal biliary stents' distal portion crossing the duodenal main papilla is safe and feasible for patients with malignant hilar bile duct obstruction. Bilateral metal biliary stents is an independent protective factor for the patency time of metal biliary stents. Age >60 years, disease type as hepatocellular carcinoma, preoperative serum total bilirubin >200 μmol/L are independent risk factors for the overall survival time of patients, and bilateral metal biliary stents, anti-tumor therapy are independent protective factors for the overall survival time of patients.
ABSTRACT
Objective To evaluate the role of multi-disciplinary team (MDT) in improving the diagnosis and treatment of human herpes virus-6B (HHV-6B) encephalitis after liver transplantation. Methods MDT consultation was delivered for one rare case of HHV-6B encephalitis after liver transplantation to establish an effective individualized treatment regime. Results On the 16 d after liver transplantation, the patient developed headache, and suddenly presented with unresponsiveness, unconsciousness, coma complicated with involuntary limb twitching on the 18 d. Blood ammonia level was increased. Brain CT scan showed cerebral ischemic changes. Electroencephalography prompted the epileptic seizure. After MDT consultation, the possibility of nervous system infection after liver transplantation was considered, and medication therapy was given to control the epileptic seizure. Cerebrospinal fluid examination via lumbar puncture hinted increased intracranial pressure. Real-time fluorescent quantitative polymerase chain reaction (RT-qPCR) of the cerebrospinal fluid demonstrated that the patient was tested positive for HHV-6B nucleic acid, which confirmed the diagnosis of HHV-6B encephalitis. The immunosuppressant regime was adjusted, intravenous ganciclovir was given for antiviral treatment, and active interventions were delivered to prevent and treat relevant complications. Epileptic seizure disappeared after 4 d, and neurological symptoms were significantly alleviated after 2 weeks. After 4-week antiviral treatment, the patient was tested negative for virology testing, and the neurological function was restored to normal. Conclusions HHV-6B encephalitis rarely occurs after adult liver transplantation, which is primarily associated with the virus reactivation after use of immunosuppressant. MDT pattern may be employed to deepen the understanding of the patient's condition, formulate more effective individualized treatment regime, and enhance the clinical efficacy and safety.
ABSTRACT
OBJECTIVE@#To obtain the subtypes of the clinical hypertension population based on symptoms and to explore the relationship between hypertension and comorbidities.@*METHODS@#The data set was collected from the Chinese medicine (CM) electronic medical records of 33,458 hypertension inpatients in the Affiliated Hospital of Shandong University of Traditional Chinese Medicine between July 2014 and May 2017. Then, a hypertension disease comorbidity network (HDCN) was built to investigate the complicated associations between hypertension and their comorbidities. Moreover, a hypertension patient similarity network (HPSN) was constructed with patients' shared symptoms, and 7 main hypertension patient subgroups were identified from HPSN with a community detection method to exhibit the characteristics of clinical phenotypes and molecular mechanisms. In addition, the significant symptoms, diseases, CM syndromes and pathways of each main patient subgroup were obtained by enrichment analysis.@*RESULTS@#The significant symptoms and diseases of these patient subgroups were associated with different damaged target organs of hypertension. Additionally, the specific phenotypic features (symptoms, diseases, and CM syndromes) were consistent with specific molecular features (pathways) in the same patient subgroup.@*CONCLUSION@#The utility and comprehensiveness of disease classification based on community detection of patient networks using shared CM symptom phenotypes showed the importance of hypertension patient subgroups.
ABSTRACT
Objective:To develop and apply the optimal evidence-based practice plan for enteral nutrition management in severe acute pancreatitis (SAP) patients.Methods:We combined the best evidence and scenario analysis to form the optimal evidence-based practice plan for enteral nutrition management in patients with severe acute pancreatitis, and integrated the plan into clinical practice. According to the procedure of evidence-based practice of the JBI Evidence-based Center, 18 nurses in the intensive care unit (ICU) were trained, and 30 SAP patients were subjected to a baseline review of the implementation of nutritional support care, with obstacles addressed and analyzed. The nutritional support quality were re-examined in another 30 SAP patients after the current plan was practiced.Results:Compared with the results of the baseline review, after the implementation of this plan, the implementation rate of the reviewed indicators was significantly improved; the ICU nurses showed a significant increase in the knowledge of SAP enteral nutrition (88.9% vs 33.3%, P<0.05. Except for the correct rate of catheter selection (100.0% vs 100.0%), the correct rate of implementation of the other 8 indicators (enteral nutrition timing selection, pre-catheterization evaluation, preparation, patients′ position, nutrition preparation selection, perfusion rate regalation, energy calculation, infusion method) was significantly improved (all P value <0.05). Furthermore, both the tolerance and satisfaction of SAP patients for enteral nutrition were significantly improved (all P value <0.05). Conclusions:The application of the optimal evidence-based practice plan for enteral nutrition management of SAP patients was beneficial to standardize the practice of ICU nurses, improve the quality of clinical care and improve the tolerance and satisfaction of enteral nutrition care of SAP patients.
ABSTRACT
Objective:To investigate the risk factors of non-obstructive gastric retention before endoscopic retrograde cholangiopancreatography (ERCP) in patients with biliopancreatic disease.Methods:The matched case-control study included 109 patients with non-obstructive gastric retention before ERCP as the case group, and 218 patients without gastric retention as the control group. The patients′ medical records including comorbidities, preoperative medication and laboratory indicators were compared between the two groups. Multivariate conditional logistic regression models were subsequently used to determine the risk factors for non-obstructive gastric retention before ERCP.Results:Logistic regression revealed that the jaundice ( OR=12.359, P<0.001), opiates use ( OR=3.009, P=0.001), somatostatin use ( OR=2.445, P=0.033), fasting hyperglycemia ( OR=1.513, P=0.045), hypokalemia ( OR=4.634, P=0.001) and hyponatremia ( OR=1.805, P=0.023) were independent risk factors for non-obstructive gastric retention before ERCP in patients with biliopancreatic disease. Conclusion:Except for gastrointestinal obstruction, jaundice, opiates use, somatostatin use, fasting hyperglycemia, hypokalemia and hyponatremia are all risk factors for gastric retention in patients with biliopancreatic disease. Comprehensive evaluation and early intervention for patients showing these risk factors are needed.
ABSTRACT
Objective@#To analyze the epidemiological characteristics of adult inpatients with gas burns in the Department of Burns of Hwa Mei Hospital of University of Chinese Academy of Sciences (hereinafter referred to as the author′s unit) , so as to provide evidence for the prevention of gas burn.@*Methods@#Medical records of all inpatients with flame burns admitted to the author′s unit from January 2011 to December 2017 were collected. The percentage of adult inpatients with gas burns in total inpatients with flame burns in the same period, and their gender, age, injury season, accident place, burn severity, common compound injury, complication, population caliber, education, industry, as well as the pre-injury disease and prognosis of elderly inpatients with gas burns were retrospectively analyzed. In addition, the age, accident place, education, and industry of the floating population in the adult inpatients with gas burns were analyzed separately and compared with the total population of adult inpatients with gas burns in 7 years. Data were processed with chi-square test or Fisher′s exact probability test (Monte Carlo algorithm).@*Results@#During the 7 years, 1 490 inpatients with flame burns were admitted to the author′s unit, among which 511 were adult inpatients with gas burns, accounting for 34.30%. The number of adult inpatients with gas burns increased gradually during the 7 years, but its percentage in the total inpatients with flame burns during the same period showed no significant difference (χ2=7.087, P>0.05). Among the 511 adult inpatients with gas burns (hereinafter referred to as the patients in this group), there were 315 males and 196 females, with a male/female ratio of 1.61 to 1.00, and the middle-aged patients were the most, up to 270 cases, accounting for 52.84%. The distribution of adult inpatients with gas burns during the 7 years was significantly different in gender and age (χ2=54.810, 27.832, P<0.01). Among the patients in this group, most were injured in summer, totally 251 cases, accounting for 49.12%, and the accident place was mainly at home, totally 388 cases, accounting for 75.93%. The distribution of adult inpatients with gas burns during the 7 years was significantly different in injury season (χ2=42.254, P<0.01), but not in accident place (χ2=6.782, P>0.05). The patients in this group were mainly with moderate burns (237 cases, accounting for 46.38%), and the distribution trend of burn severity of adult inpatients with gas burns was basically the same during the 7 years (χ2=19.680, P>0.05); 176 patients (34.44%) were accompanied by inhalation injury, and 30 patients (5.87%) were accompanied by blast injury of lung; post injury complications occurred in 20 patients (3.91%). In the elderly inpatients with gas burns, 44.44% (32/72) were accompanied by pre-injury basic diseases, and the proportion of death or unhealed reached 18.06% (13/72). Most of the patients in this group were permanent residents (358 cases, accounting for 70.06%) and received secondary education (304 cases, accounting for 59.49%), and the majority of them were engaged in manufacturing/construction (138 cases, accounting for 27.01%), self-employed business (90 cases, accounting for 17.61%), and catering (90 cases, accounting for 17.61%) industries. The distribution of adult inpatients with gas burns during the 7 years was significantly different in population caliber, education, and occupation (χ2=17.496, 29.898, 88.896, P<0.05 or P<0.01). Among the patients of this group, the floating population were mainly young (90 cases, accounting for 58.82%) and middle-aged (62 cases, accounting for 40.52%), with main accident place at home (97 cases, accounting for 63.40%), generally received secondary education (101 cases, accounting for 66.01%), and were mainly engaged in manufacturing/construction (71 cases, accounting for 46.41%), self-employed business (26 cases, accounting for 16.99%), and catering (20 cases, accounting for 13.07%) industries. Compared with the total adult inpatients with gas burns in 7 years, the floating population were younger, more injured in the workplace, and more concentrated in industry (χ2=42.924, 9.390, 27.819, P<0.01).@*Conclusions@#Gas burn was the leading injury cause of inpatients with flame burns in the author′s unit, which mainly occurred in summer and at home; the patients were mainly male, young and middle-aged, and permanent residents, most of which were with moderate burn, often accompanied by inhalation injury. Most of the patients were of secondary education, engaged in manufacturing/construction, self-employed business, and catering industries, among which the floating population were younger, more injured in the workplace, and more concentrated in industry. In order to prevent gas burn, we should pay more attention to the propaganda and education of gas safety among young and middle-aged men, floating population, retired old people and housewives, especially in summer, we should do a good job in gas safety inspection at home. In addition, we should urge enterprises to further strengthen the supervision of production safety.
ABSTRACT
@#【Objective】To test the hypothesis that inhibiting sodium absorption via the epithelial sodium channel（ENaC） will increase ocular hydration and cure the rabbit′ s dry eye induced by scopolamine. 【Methods】In the experiment，24 New Zealand rabbits weighing about 2.0- 2.5 kg were divided into 3 groups：tested group（8 rabbits）， control group （8 rabbits），and treatment group （8 rabbits）. For the rabbits in the tested group，they were given subcutaneous injection of scopolamine 4 times a day for 12 consecutive days to induce the dry eye. For the rabbits in the control group，they accepted subcutaneous injection of saline solution. For the rabbits in the treatment group ，they were firstly given the same treatment as the rabbits in the tested group. Then，the local regions in their right eyes received the application of 100 mmol/L amiloride （a sodium channel inhibitor）. Meanwhile，the local regions in their left eyes received the application of equivalent saline solution. We detected ENAC α and ENAC γ subunits of epithelial sodium channel in conjunctival epithelium by fluorescence quantitative PCR and detected the opening of epithelial sodium channel by short- circuit current technology. Finally，we compared the ENaC α and ENaC γ gene expression，corneal fluorescein sodium staining and tear secretion among the 3 groups. Fluorescence quantitative PCR was used to detect ENaC α and ENaC γ subunits of epithelial sodium channel in conjunctival epithelium and short-circuit current was used to detect the opening of epithelial sodium channel. The ENaC α and ENaC γ gene expression，corneal fluorescein sodium staining and tear secretion （immerged length） were compared among 3 groups.【Results】 The results showed that the quantity of tear secretion was（17.00 ± 0.37）mm for the control group，（4.42 ± 1.34）mm for the tested group（P<0.001 vs Control，n=8） and（14.25 ± 0.54）mm for the treatment group（P>0.05 vs Control，n=8）. The results of short-circuit current detection showed that the sodium current was（5.72 ± 0.35）μA /cm2 in normal model and（12.24 ± 0.54）μA /cm2 in dry eye model（P<0.001）. After Amiloride treatment，the sodium current decreased to（4.00 ± 0.61）μA/cm2 （P>0.05） and there was no statistical difference compared with the normal group. According to the results of fluorescence quantitative PCR，the expression of ENaC α and ENaC γ subunits and IL- β in in dry eye model were up-regulated（P<0.01） compared with that in normal group. After topical amiloride application，there were no statistical differences in inflammatory cytokines IL- 1 β，ENaC α，and ENaC γ between the normal group and treatment group（P>0.05，n=8）. After treatment，tear secretion increased （P<0.001），and ocular surface staining improved significantly.【Conclusion】 Topical application of amiloride increase the quantity of preocular tears owing to inhibition of conjunctival sodium channels and could provide an effective new therapy for chronic dry eye.
ABSTRACT
From June to November 2016, 5 patients with severe burns were admitted to our unit. Broad-spectrum antibiotic and fluconazole were used on patients as earlier empirical anti-infection therapy of bacteria and fungi. Seven to twenty-one days after injury, 5 patients developed fungal infection. Antifungal agents of caspofungin, voriconazole, and amphotericin B liposomewere were used according to the results of fungal culture, and the infected wounds were also treated with repeated debridement and dressing change. Multiple autologous skin grafts were performed after infection control of wounds. With the above antifungal infection treatment for 5 to 11 days, 2 patients′ condition tended to be stable, and no fungus was found in wound secretion after cultured for many times. The patients were discharged with wounds healed after 52 to 54 days′ hospital stay. Due to severe burns degree and or elder age, fungal infection aggravated and expanded to the trunk in the other 3 patients, then developed into burn sepsis, resulting in patients died of multiple organ failure secondary to sepsis.

Methods Acute pancreatitis patients admitted in Changhai Affiliated Hospital of Navy Medical University from December 2018 to February 2019 were enrolled, and 120 patients were selected using random number table method. Self-made general questionnaire, self-rating depressing scale, self-rating anxiety scale and coping style questionnaire were used for investigation and patients′ psychological status was evaluated. Results In this survey, 109 questionnaires were collected and eligible for final analysis. The incidence of depression in patients with acute pancreatitis was 44. 0％, and the incidence of anxiety was 20. 2％. Male patients had significantly lower anxiety and depression than women. The levels of anxiety and depression in the 31-50 age group were significantly lower than those in other age groups. The level of anxiety in patients with pancreatitis with children was significantly lower than in patients without children. The coping style of "solving problem" was significantly negatively correlated with depression and anxiety level. The"self-blame" coping style was significantly positively correlated with depression and anxiety level. The"rationalized"coping style was positively correlated with the level of depression. Conclusions The mental health status of patients with acute pancreatitis was not optimistic. Different coping styles were important factors affecting the level of anxiety and depression.

ABSTRACT
Objective To evaluate the application effect of nursing management in the follow-up of patients with recurrent acute pancreatitis (RAP).Methods During January 2016 and January 2017,the clinical data of RAP patients admitted in Changhai Hospital of Navy Medical University was collected.Selfcontrol method was used to establish a prospective cohort study.Meticulous nursing management mode was applied to follow up the patients for 12 months.Patients' compliance,symptom improvement,patients' satisfaction and other markers are evaluated using questionnaires to assess the effect of meticulous nursing management once every 3 months.The data over 12 months were collected.Results Sixty-four RAP patients were finally included.The average follow-up period was 19.7 ±3.4 months.Before admission,the average disease course was(4.21 ± 3.95) years.30 patients (46.9％)had a history of drinking;33 patients (51.6％)had a history of smoking.25 patients (39.1％) had abnormal blood lipid and 40 patients (62.5％) had the dietary habit of high lipid and high protein.The etiology included alcohol (n =10,15.6％),high lipid (n =7,10.9％),biliary diseases (n =1,1.6％),idiopathic causes (n =46,71.9％) and abnormal BMI (n =49,76.6％).After the meticulous nursing management,the frequency of pancreatitis,VAS score of pain and alcohol intake situation was obviously lower than before intervention [(0.50 ±0.85) times/year vs(2.77 ±2.52)times/year;(1.84 ±2.54)vs(6.47 ±2.15);2 cases vs 30 cases].The number of patients who took medicine on time and BMI were obviously decreased[(52 cases vs 13 cases;(23.26 ± 3.85) kg/m2 vs (21.92 ± 4.27)kg/m2)],and the differences were statistically significant (P ＜0.01).Patients' satisfaction with this nursing model was 4.90 ± 0.56.Conclusions The implementation of the new meticulous nursing management model can effectively alleviate patient's symptom condition and improve the compliance behavior and life quality of the patients.
ABSTRACT
Objective To evaluate effects of flush fluid of different temperatures on pain, comfort and adverse reactions in patients receiving choledochoscopy via T tube for residual bile duct stones. Methods Patients who underwent choledochoscopy were divided into the experimental group ( 36℃ saline was used as flush fluid) and control group ( room temperature saline was used as flush fluid) randomly. Pain degree, comfort degree, procedure time, the total amount of flush fluid, infusion speed and adverse reactions were recorded and analyzed. Results A total of 100 cases were included, 50 cases in each group. There was no significant difference between the two groups in their education level, working condition, operation methods, T-tube size, necessity for lithotripsy, procedure time, total amount of flush fluid and infusion speed (all P>0. 05). The pain scores were 1. 0(1. 00, 2. 00) and 2. 0(1. 00, 3. 25) (Z=-2. 158,P=0. 031) and the comfort scores were 6. 0(5. 00, 7. 25) and 5. 0(2. 00, 6. 00) (Z=-3. 384,P=0. 001) in the experimental group and the control group, respectively. There was significant difference in the change rate of heart rate during and before procedure between the two groups (-4. 07％± 10. 76％ VS 0. 30％± 10. 23％, P=0. 046) . The incidence of postoperative diarrhea in the experimental group and the control group was 6％( 3/50) and 22％ ( 11/50 ) , respectively (χ2=5. 316, P=0. 021 ) . Conclusion 36℃ saline flush can reduce pain scores, improve comfort degree and reduce the incidence of postoperative diarrhea after procedure in patients undergoing choledochoscopy via T tube.
ABSTRACT
Objective To analyze the efficacy of endoscopic ultrasonography-guided biliary drainage ( EUS-BD) for malignant obstructive jaundice and the management of adverse events. Methods Clinical data of 12 patients with malignant obstructive jaundice, who underwent EUS-BD between April 2016 and January 2017, were retrospectively analyzed. All patients received EUS-BD after unsuccessful ERCP, including EUS-guided hepaticogastrostomy ( EUS-HGS ) , EUS-guided antegrade stenting ( EUS-AS ) , and EUS-guided choledochoduodenostomy(EUS-CDS). Procedure outcomes, serum bilirubin and liver enzyme levels before the procedure and 1 week after, complications, treatment results, hospitalization time and follow-up were recorded. Results Two patients underwent EUS-HGS, 3 underwent EUS-AS, and 7 underwent EUS-CDS. Total bilirubin ( t=3. 462, P=0. 005 ) , direct bilirubin ( t=3. 351, P=0. 006 ) , alanine transaminase (t=2. 399, P=0. 037), γ-glutamate transpeptidase (t=3. 256, P=0. 031) reduced significantly after the procedure. Two patients ( 16. 67％) developed complications. A patient undergoing EUS-HGS developed bile leakage, biliary peritonitis, and pneumoperitoneum. A patient undergoing EUS-CDS developed upper gastrointestinal bleeding. Both patients were successfully treated. There were no other adverse events, such as acute pancreatitis, subcutaneous emphysema, pneumothorax and emphysema. No procedure-related death occurred. The mean hospital stay was 13. 75 ± 6. 92 days ( range 5-26 days ) . Conclusion EUS-BD is a safe substitute after unsuccessful ERCP when performed by experienced biliary endoscopists. However, intensive care is necessary after the procedure for early detection and management of complications.
ABSTRACT
This paper summarized nursing points for caring 12 cases undergoing endoscopic ultrasonography guided biliary drainage(EUS-BD) in the treatment of malignant obstructive jaundice.All patients received EUS-BD after unsuccessful endoscopic retrograde cholangiopancreatography,including 5 patients undergoing EUS guided hepaticogastrostomy(EUS-HGS) and 7 patients undergoing EUS guided choledochoduodenostomy(EUS-CDS).Nursing points included:preoperative assessment,psychological care,preoperative gastrointestinal preparation,intraoperative cardiopulmonary function monitoring,collaboration in operation,postoperative monitoring,observation and nursing care for complications such as bleeding,bile leakage and the others.The average hospital stay was 10～16 d.Two patients developed complications(16.67％).A patient undergoing EUS-HGS developed bile leakage,biliary peritonitis,and pneumoperitoneum after the procedure,but was successfully recovered by placement of a second fully covered self-expendable metal stent in the primary metal stent,percutaneous abdominal drainage and antibiotic treatment.A patient undergoing EUS-CDS developed gastrointestinal bleeding,and was successfully treated with radiological intervention.
ABSTRACT
Objective To observe the characteristics of spectral-domain optical coherence tomography (SD-OCT) for leakage point in acute central serous chorioretinopathy (CSC).Methods A total of 21 acute CSC patients (21 eyes) were enrolled in this retrospective study,including 17 men (17 eyes) and 4 women (5 eyes).The mean age was (47.3±8.8) years (range 35-66 years).The mean duration was (1.6±0.8) months (range 0.5-3.0 months).All patients were underwent mydriatic fundus photography,SD-OCT examination and fluorescein fundus angiography (FFA).SD-OCT and FFA images were carefully compared to observe the SD-OCT examination characteristics of fluorescence leakage point.Results 21/21 eyes had one fluorescein leakage point.In addition to serous retinal detachment,leakage point in the SD-OCT examination showed retinal pigment epithelium (RPE) protrusion in 10 eyes (47.6 ％),RPE detachment in 7 eyes (33.3 ％),highly reflective areas suggesting fibrinous exudate in the subretinal space in 3 eyes (14.3 ％),and RPE defect in 1 eye (4.8 ％).Conclusion The SD-OCT characteristics of acute CSC include RPE protrusion,RPE detachment,highly reflective areas suggesting fibrinous exudate in the subretinal space and RPE defect.
ABSTRACT
This article was aimed to carry a comparative study on the quality of 16 populations of wild herbs of rare and endangered plant ofPsammosilene tunicoidesin order to provide a basis for its domestication, GAP and selective breeding. Methods for determination of moisture content, total ash and extract content were taken in this comparative study. The results showed that different populations had different moisture content, total ash and extract content. The moisture content and the total ash ofXiang-Shan population were the lowest; and the extract content was the highest. The total ash ofLiu-De population was the highest; and the extract content was the lowest. The moisture content ofShun-Zhou population was the highest. It was concluded that different populations had different quality among 16 populations of wild herbs. Therefore, there was a probability to choose the best population.
ABSTRACT
Objective To examine the impact of academic pressure,self-esteem,and their interactive effect on student burnout.Methods A total of 1 497 middle school students were investigated with three questionnaires.Results The scores of academic pressure,self-esteem,exhaustion,cynicism,efficacy were 9.95 ± 4.52,21.90±5.04,11.84±4.05,10.84±4.88,20.60±5.47 respectively.Results indicated that the main effects of academic pressure and self-esteem on student bumout were significant.Specifically,academic pressure affected exhaustion (β =0.467,P＜0.01) and efficacy (β=0.134,P＜0.05) ; self-esteem affected cynicism (β=0.588,P＜0.01) and efficacy (β=0.549,P＜0.01).Self-esteem moderated the impact of academic pressure on student burnout(β=-0.216,P＜0.01).The impact of academic pressure on student burnout became lower when their self-esteem grows.Self-esteem moderated the impacts of academic pressure on exhaustion and efficacy,but the moderate effect of selfesteem on the influence of academic pressure on efficacy was very small and could be neglected.Conclusion Academic pressure,self-esteem affect student burnout,and self-esteem moderate the influence of academic pressure on student burnout negatively.
ABSTRACT
Objective To evaluate the effects of connective tissue growth factor (CTGF) on corneal neovascularization.Methods Twenty-five Wistar rats were divided into control and experimental groups.Corneal neovascularization (CNV) was induced by alkaline burn of the cornea with 1 mmol/L NaOH.On the 1st,4th,7th,and 14th day,CNV was observed,and the expression of CTGF was investigated with immunohistochemical method in rat cornea at the different time point.Results On the 4th day,7th day and 14th day after alkaline burn,the areas of CNV were (12.740 ±2.536) mm2,(26.068 ± 10.028) mm2,and (37.588 ± 8.066) mm2,respectively.CTGF was rarely expressed in the cornea of normal rats,and then CTFG expression was quickly increased after alkaline burn,reached the highest level on the 4th day (1.714 ± 0.185),and then declined remarkably on the 7th day (1.334 ± 0.198).Conclusions CTGF might be involved in the formation process of corneal neovascularization after corneal alkali burn.
