H 1-antihistamines are widely used in the treatment of various allergic diseases, but there are still many challenges in the safe and rational use of H 1-antihistamines in pediatrics, and there is a lack of guidance on the prescription review of H 1-antihistamines for children.In this paper, suggestions are put forward from the indications, dosage, route of administration, pathophysiological characteristics of children with individual difference and drug interactions, so as to provide reference for clinicians and pharmacists.

Objective:To investigate the prevalence of the decline of intrinsic capacity(IC)and to explore the effect of intrinsic capacity decline on falls and hospital readmission during 1 year follow-up.Methods:A total of 311 elderly patients treated in Geriatrics Department of Zhejiang Hospital were enrolled.General information and intrinsic ability data, including cognitive(simple mental state inventory), motor(Tinetti-Balance Scale and 4 m test), vitality(grip strength and mini-nutrition assessment table), perception(self-rated vision or hearing impairment), and psychosocial(Geriatric depression scale), were collected at admission.Falls and hospital readmission within 1 year after discharge were followed up.Multivariate Logistic regression analysis was used to investigate the relationship of baseline intrinsic ability at admission with falls and hospital readmission during 1-year follow-up.Results:Of 311 elderly hospitalized patients, 282(90.7%)had intrinsic capacity decline.During 1 year follow-up, 38 elderly patients(12.2%)had falls and 69 elderly patients(22.2%)were hospital readmitted.After adjusting for confounding factors such as age, gender, education level, comorbidities, multiple medications, fear of falling, and assistive tool use and so on, Logistic regression analysis showed that decreased balance ability was a risk factor for falls within 1 year in elderly patients( OR=3.515, 95% CI: 1.089-11.346, P=0.036), and slow walking speed was a risk factor for one-year hospital readmission( OR=2.426, 95% CI: 1.181-4.983, P=0.016). Conclusions:Decreased motor capacity is closely associated with falls and hospital readmission within 1 year in older patients.Great attention should be paid to the assessment and intervention of motor ability in elderly patients.

Worldwide, the incidence of cancer is greatest in China. Tumor screening is effective to achieve early diagnosis, improve prognosis, increase the quality of life, and reduce mortality among cancer patients. Positron emission tomography/computed tomography (PET/CT) imaging provides metabolic data to support initial staging, treatment planning, and response evaluation in tumor screening, as well as tumor follow-up. The progressive integration of PET/CT imaging in radiotherapy has its basic principle in the biological heterogeneity of inter- and intra-tumor malignant lesions, and the radiation dose is required to be adjusted to achieve effective local tumor control among cancer patients. In addition, PET/CT imaging provides data on the biological features of tumor lesions, such as metabolism, hypoxia, and proliferation, which is useful to identify radiation-resistant regions and optimize treatment plans. These data are effective to reduce the uncertainty and variability in the anatomic description of tumor sites. This review summarizes the application of PET/CT imaging in common tumors.

The combination of conventional single-photon emission computed tomography (SPECT) and computed tomography (CT) may display the morphological changes of lesions and distribution of imaging agents, which is effective to improve the imaging sensitivity and specificity of tumors and non-tumor diseases. SPECT/CT is feasible to analyze the anatomical structure and metabolic status through displaying multi-site lesions with single imaging, thereby improving differential diagnosis and diagnostic accuracy of diseases. In addition, the novel mixed SPECT/CT device shortens the duration of image acquisition and provides precise attenuation correction and fusion imaging, which provides a scientific basis for rational selection of treatment regimens in clinical practice. This review describes the advances in clinical application of SPECT/CT.

Objective:To explore the risk factors of intensive care unit-acquired weakness (ICU-AW), and to establishment and verify its risk prediction model.Methods:A modeling group of 231 patients who met the inclusion criteria and were admitted to the intensive care unit (ICU) of the First Hospital of Jiaxing from July 2019 to June 2020 was collected by convenience sampling method. According to whether they developed ICU-AW, they were divided into ICU-AW group (55 cases) and non ICU-AW group (176 cases). The clinical data were collected concerning patients' individual information, disease-related factors, treatment-related factors and laboratory indicators, and the differences of the above indexes between two groups were compared. Logistic regression was used to analyze the ICU-AW risk factors and a risk prediction model was constructed. Calculate the area under ROC curve (AUC) to test the prediction effect of the model. At the same time, 60 patients who admitted to ICU from July to October 2020 and met the standards were collected to verify the model.Results:Compared with non ICU-AW group, there were more males in ICU-AW group [61.8% (34/55) vs. 44.3% (78/176), P < 0.05], with higher levels of systemic inflammatory response syndrome (SIRS), sepsis, immobilization and the use of neuromuscular blockers [SIRS: 30.9% (17/55) vs. 3.4% (6/176), sepsis: 12.7% (7/55) vs. 2.3% (4/176), immobilization: 72.7% (40/55) vs. 39.2% (69/176), the use of neuromuscular blockers: 50.9% (28/55) vs. 14.2% (25/176), all P < 0.05], and acute physiology and chronic health evaluationⅡ(APACHEⅡ) score, blood lactic acid level and duration of mechanical ventilation, length of hospital stay were all increased [APACHEⅡ score: 18 (15, 24) vs. 12 (8, 17), blood lactic acid (mmol/L): 2 (1, 2) vs. 1 (1, 2), duration of mechanical ventilation (days): 7 (4, 12) vs. 2 (2, 5), length of hospital stay (days): 10 (6, 16) vs. 5 (3, 9), all P < 0.05]. SIRS, APACHEⅡ score, duration of mechanical ventilation and blood lactic acid were included to construct a risk prediction model [odds ratio ( OR) values were 4.835, 1.083, 1.210, 1.790, P values were 0.018, 0.013, 0.015, 0.013]. The model equation was P = exp [-5.207+(1.576×SIRS)+(0.079×APACHEⅡ)+(0.191×duration of mechanical ventilation)+(0.582×blood lactic acid)]. Internal verification: Calibration diagram showed the calibration curve above the ideal curve, AUC = 0.888, 95% confidence interval (95% CI) was 0.839-0.938; when the cut-off value was 0.166, the sensitivity was 89.1%, the specificity was 75.6%, and the maximum index was 0.649. External verification: Calibration diagram showed that the calibration curve was above the ideal curve, and the plotted AUC = 0.853, 95% CI was 0.753-0.953. When the cut-off value of the corresponding predictive risk value was 0.367, the sensitivity was 68.8%, the specificity was 86.4%, and the maximum approximate index was 0.552. Conclusion:The risk prediction model of ICU-AW constructed in this study has good consistency and prediction efficiency, which can provide reference for medical personnel to identify high-risk groups of ICU-AW patients in the early stage and provide targeted interventions in advance.

Objective To investigate the detection rate of motoric cognitive risk syndrome (MCR)and explore the possible risk factors.Methods A total of 429 elderly patients from geriatric department of Zhejiang Hospital from October 2014 to September 2018 were recruited in the crosssectional study.General information and functional assessment including fall history,self-reported visual impairment and hearing impairment,depressive symptom,cognitive function and gait speed were collected.Patients with MCR were screened out according to the MCR diagnostic criteria.Multiple logistic regression analysis was used to analyze the associated risk factors.Results Seventeen patients(4.0％)met the MCR diagnostic criteria.The proportions of obesity,polypharmacy,cerebral vascular diseases,self-reported hearing impairment,depressive symptoms and slow gait were higher in MCR patients than in non-MCR patients(P＜0.05).Compared with non-MCR patients,MCR patients had lower mini mental state examination (MMSE) scores (P ＜ 0.01).After adjusting for associated confounding factors,multiple logistic regression analysis showed obesity (OR =3.74,95 ％ CI:1.14-12.23,P ＜ 0.05) and depressive symptoms (OR =5.79,95％ CI:1.76-19.06,P ＜ 0.01) were risk factors for MCR.Conclusions MCR is not uncommon in elderly patients.Obesity and depressive symptoms are closely associated with an increased risk of MCR.

Objective To assess the predictive value for survival of BioCliM index in liver cirrhosis caused esophageal and gastric varices bleeding(EGVB)treated by endoscopic variceal ligation(EVL),endoscopic injection sclerotherapy(EIS)and endoscopic tissue adhesives(ETA).Methods From December 2006 to December 2011, the clinical data of 166 hospitalized patients with first occurrence of EGVB caused by liver cirrhosis and received endoscopic therapies were retrospectively analyzed.The scores of model for end-stage liver disease(MELD),model for end-stage liver disease-Na(MELD-Na),BioCliM index and Child-Turcotte-Pugh(CTP)were calculated. Receiver operating characteristic(ROC)curve and area under the curve(AUC)were applied to assess the accuracy of the four models in one-year and two-year prognosis evaluation,and to obtain the best critical value,and the mortality rates were compared among groups.Chi-square test,t test and rank-sum test were performed for statistical analysis.Results Among 166 patients,the levels of creatinine,bilirubin,albumin,sodium,international normalized ratio and prothrombin time were(0.10 ± 0.06)mmol/L,(0.02 ± 0.01)mmol/L,(30.13 ± 5.06)g/L, (139.13 ± 4.27)mmol/L,1.50 ± 0.32 and(17.83 ± 2.88)s,respectively.During the one-year and two-year follow-up,there were 14 patients and 23 patients dead,respectively.During the one-year and two-year follow-up, the incidences of portal thrombosis of death group were lower than those of survival group(10/14 vs 93.4%,142/152;73.9%,17/23 vs 94.4%,135/143);and the differences were statistically significant(χ2=8.029 and 10.774, both P<0.01).During the one-year and two-year follow-up,BioCliM indexes of death group were 0.12(-0.82, 1.44)and -0.81(-0.87,0.92),respectively,which were both higher than those of survival group(-0.84,-0.94 to -0.73;and -0.84,-0.94 to -0.72),and the differences were statistically significant(Z= -3.074 and -2.260,both P<0.05).During the one-year follow-up,the AUC values of MELD,MELD-Na,BioCliM index and CTP score were 0.698,0.691,0.749 and 0.723,respectively.During the two-year follow-up,the AUC values of MELD,MELD-Na,BioCliM index and CTP score were 0.587,0.582,0.647 and 0.633,respectively. But there was no statistically significant difference in AUC between BioCliM index and MELD,MELD-Na,and CTP score in one-year and two-year follow-up for prognosis evaluation(Z=0.509,0.566,0.271,0.687,0.731 and 0.162,respectively;all P>0.05).The best critical value of BioCliM index was -0.234.Followed up for one year and two years,the mortality rates of patients with BioCliM index over -0.230 were higher than that of patients with BioCliM index less than -0.234(31.0%,9/29 vs 3.6%,5/137;34.5%,10/29 vs 9.5%,13/137);and the differences were statistically significant(χ2=23.242 and 12.526,both P<0.01).Conclusions BioCliM index has a high accuracy in one-year and two-year mortality rate evaluation in liver cirrhosis patients with EGVB and received endoscopical therapies.We should pay attention to the prognosis evaluation before the endoscopical therapy.

Objective To investigate the changes of peripheral blood expression levels of soluble fibrinogen-like protein 2 (sFGL2) in patients with chronic hepatitis B (CHB) before and after antiviral treatment.Methods From July 2013 to December 2014,initial CHB patients with entecavir antiviral therapy and healthy controls were enrolled.Clinical data at baseline and during follow-up were collected.Plasma levels of sFGL2 of all the included objects were measured by enzyme-linked immunosorbent assay (ELISA).All the patients received liver biopsy at baseline,and part of patients received a second liver biopsy at week 78 after treatment.The expression of sFGL2 in liver tissues were examined by immunohistochemistry.T test,Wilcoxon test and correlation analysis were performed for statistical analysis.Results A total of 71 CHB patients and 20 healthy controls were enrolled.At baseline,the level of plasma sFGL2 of CHB patients was significantly higher than healthy controls (105.6 μg/L (78.3 μg/L to 151.6 μg/L) vs 25.2 μg/L (18.8 μg/L to 34.3 μg/L),Z=-5.887,P＜ 0.01).The plasma sFGL2 level of patients with liver cirrhosis was 146.0 μg/L (111.3 μg/L to 166.8 μg/L),which was higher than that of patients without liver cirrhosis (79.0 μg/L (65.4 μg/L to 107.4 μg/L)),and the difference was statistically significant (Z=-4.912,P＜0.01).Plasma levels of sFGL2 were positively correlated with liver stiffness,liver inflammation and fibrosis stages (r=0.426,0.240 and 0.655;all P＜0.05).At 26 weeks and 52 weeks after treatment,the plasma levels of sFGL2 were 89.1 μg/L (69.8 μg/L to 125.5 μg/L) and 75.8 μg/L (53.4 μg/L to 98.9 μg/L),respectively,which gradually decreased compared with that at baseline (26 weeks vs baseline Z=-4.499,P＜0.01;52 weeks vs 26 weeks Z=-4.762,P＜0.01).Furthermore,at baseline the number of sFGL2 positive cells in the liver tissue of liver cirrhosis group was 33.0 ± 10.4,which was higher than that of non-liver cirrhosis group (17.6 ±6.7),and the difference was statistically significant (t=7.541,P＜0.01).Compared with that at baseline (24.5±2.0),the number of sFGL2 positive cells in liver tissue at week 78 after treatment decreased (11.3± 1.6),and the difference was statistically significant (t=11.980,P＜0.01).Conclusion Plasma level of sFGL2 is closely correlated with the degree of liver inflammation and fibrosis in CHB,and the plasma level of sFGL2 significantly decreases after long-term antiviral therapy.

Objective To investigate the correlation between the frailty and nutritional status of the elderly hospitalized patients.Methods A total of 244 hospitalized patients were enrolled in this investigation. By using comprehensive geriatric assessment (CGA),patients answered these questions together with experts (questionnaire assessment by professional instructions). Researchers input the result into computer at same time. Results Compared with normal patients,frailty patients were older (P<0.001),and had lower ability to take care of themselves (P<0.001),in other words,they had more demands from their families and carers in terms of medical care (P<0.01). In addition, frailty patients had higher risks of having depressive symptom (P=0.016),cognitive impairment (P<0.001), living function disability (P<0.001),as well as malnutrition (P<0.001). Regression analysis result showed a negative correlation between frailty and nutrition (P=0.005).Conclusions Malnutrition is closely related to frailty,and malnutrition patients and patients with risks of malnutrition were easily to acquire frailty.

Objective To explore the molecular basis of the characteristics of the serum auto-fluorescent spectrum in patients with ovarian cancer and the changes that might be induced by surgery. Methods Using fluorospectrophotometer and 300nm excitation light,the serum auto-fluorescent spectrum of 84 patients with ovarian cancer before and after the surgery and 30 healthy people were detected. Meanwhile, the serum tumor signs (CEA, CA199 and CA125), hemoglobin and plasma albumin level of all patients with ovarian cancer were detected. Their correlation with the fluorescence spectral characteristic parameters were analyzed. Results Compared with healthy people, the serum auto-fluorescent spectrum in patients with ovarian cancer exhibited purple-shifted position of λ2 peak and red shift in λ4 peak,had higher peak extent inλ1, λ2, λ4 and λ6 peak, and larger peak area of λ1, λ2, λ3, λ4 and λ6. Compared with those in ovarian cancer patients before surgery, the serum auto-fluorescent spectrum in these patients after operation had red shifts in λ1, λ2 and λ3 peak, lower peak extent in λ1, λ2, λ3 and λ4, and smaller peak area in λ1, λ2, λ3,λ4 and λ6 peak. In ovarian cancer patients, the serum level of CEA was positively correlated with the λ2 peak extent and the peak area of λ2 and λ3, while the serum level of CA125 was positively correlated with the peak extent of λ1-λ4 and λ6 and the peak area of λ1-λ3. The serum level of CA199 was negatively correlated with the λ2 position and positively correlated with the peak extent of λ1-λ6 and the peak area ofλ1-λ3 and λ6 in patents with ovarian cancer. Besides, the serum albumin was positively correlated with theλ2 peak position and negatively with the peak extent of λ1-λ6 and the λ1-λ3 peak area, while the level of hemoglobin was positively correlated with λ1 peak position. Conclusions The elevated serum tumor markers and lower albumin (plasma) level lead to the changes of the serum autofluorescence spectra characteristic parametersin in patients with ovarian cancer.These changes can be modestly corrected by surgery.
