ABSTRACT
Objective To establish a prediction model for tuberculosis incidence in Nantong area by multivariate regression analysis, and to provide theoretical support for the implementation of combined prevention work in this area. Methods A total of 37 338 registered patients with pulmonary tuberculosis in Nantong City from 2010 to 2021 were enrolled in the observation group. A total of 28,721 healthy people who underwent physical examination during the same period were selected as the control group. Results From 2010 to 2021, there were a total of 37 338 cases of pulmonary tuberculosis in central Nantong. From 2010 to 2015, more than 3,000 cases were reported annually, with the largest number (4 142 cases) in 2011, accounting for 11.09% of the total. The number of cases reported from 2016 to 2021 was all less than 3 000, and the number of cases reported from 2021 was the least , 1 803 cases, accounting for 4.83% of the total. The number of cases decreased each year in the past 12 years. The incidence of pulmonary tuberculosis in males was 70.97% (26 497 cases) and that in females was 29.03% (10 841 cases). In terms of age, the lowest incidence rate was 0.06% (23 cases) in the age group of 0-9 years old, and the highest incidence rate was 19.56% (7 304 cases) in the age group of 60-69 years old. Logistics regression analysis showed that male, age ≥60 years old, occupation as a farmer and smoking history were the risk factors for pulmonary tuberculosis (P < 0.05). ROC curve results showed that the AUC value of the risk prediction model for pulmonary tuberculosis in the Nantong area was 0.872, with a predictive sensitivity of 86.32% and a specificity of 89.21%. Conclusion There are many risk factors for pulmonary tuberculosis in Nantong area, and different factors interact and influence each other. The construction of a risk prediction model for pulmonary tuberculosis can better predict the clinical incidence, which is helpful to guide clinical diagnosis and treatment.
ABSTRACT
Objective:To evaluate the effect of flurbiprofen postconditioning on the permeability of blood brain barrier in a rat model of focal cerebral ischemia-reperfusion (I/R) injury.Methods:Eighty healthy male Wistar rats, aged 8-9 weeks, weighing 280-320 g, were divided into 4 groups ( n=20 each) using a random number table method: sham operation group (group Sham), focal cerebral I/R group (group I/R), lipo-microballoons group (group V) and flurbiprofen 10 mg/kg group (group F). Focal cerebral I/R model was established by left middle cerebral artery occlusion for 2 h followed by 24-h reperfusion in anesthetized rats.Flurbiprofen 10 mg/kg (group F), the equal volume of lipo-microballoons (group V) or the equal volume of normal saline (group Sham and group I/R) was injected via the tail vein at the onset of reperfusion.The rats were sacrificed at 24 h of reperfusion, brains were immediately removed, and cerebral tissues were obtained for measurement of brain water content, Evans blue content, expression of matrix metalloproteinase-9 (MMP-9) in ischemic penumbra (by immuno-histochemistry), and expression of phosphorylated p38 mitogen-activated protein kinase (p-p38 MAPK) and inducible nitric oxide synthase (iNOS) in ischemic penumbra (by Western blot). Results:Compared with Sham group, brain water content and Evans blue content in brain tissues were significantly increased, and the expression of MMP-9, p-p38 MAPK and iNOS in ischemic penumbra was up-regulated in I/R, V and F groups ( P<0.05). Compared with group I/R, brain water content and Evans blue content in brain tissues were significantly decreased, and the expression of MMP-9, p-p38 MAPK and iNOS in ischemic penumbra was down-regulated in group F ( P<0.05), and no significant change was found in the above parameters in group V ( P>0.05). Conclusion:Flurbiprofen postconditioning can decrease the permeability of blood brain barrier during focal cerebral I/R in rats, and the mechanism may be related to inhibiting the activation of p38 MAPK/iNOS signaling pathway and down-regulating the expression of MMP-9.

ABSTRACT
OBJECTIVE： To investigate the effects of different doses of total alkaloids from Aconitum racemulosum （ARTA） on serum inflammation factors and FOS protein expression in synovial tissue of joint in collagen-induced arthritis （CIA） model rats， and to investigate its potential mechanism of anti-rheumatoid arthritis （RA）. METHODS： Male SD rats were randomly divided into blank group， model group， positive group （Compound dexamethasone acetate ointment， 0.2 g/kg）， ARTA low-dose， medium-dose and high-dose groups （56.26， 112.50， 225.00 mg/kg， by the weight of ARTA in the extract）， with 10 rats in each group. Except for blank group， other groups were given subcutaneous injection of Bovine collagen Ⅱ emulsified with incomplete Freund’s adjuvant into the left foot to establish CIA model； the left foot were smeared with relevant medicine from the day of modeling. Blank group and model group were smeared with constant volume of 65％ ethanol， 3 times a day， for consecutive 28 days. On the 7th， 14th， 21st and 28th day of administration， the thickness of left hind toe was measured with vernier caliper， and the degree of foot swelling was calculated. The serum contents of IL-1β， IL-6 and TNF-α in rats were measured by ELISA after last administration. The expression of FOS protein in synovial tissue was determined by immunohistochemical method [expressed by HIS]. The comprehensive score was conculated by entropy weight method. Effects of each dosage on above indexes of CIA model rats were evaluated with the comprehensive score. RESULTS： Compared with blank group， the degree of foot swelling， serum content of inflammatory factors and HIS value were increased significantly in model group （P＜0.05）. Compared with model group， the degree of foot swelling in each administration group， serum contents of IL-1β， IL-6 and TNF-α， HIS in positive group and ARTA high-dose group， serum contents of IL-6 and TNF-α in ARTA medium-dose group as well as serum content of TNF-α in ARTA low-dose group were decreased significantly（P＜0.05）. Comprehensive score of above indicators were 0.37（positive group）， 0.31（ARTA high-dose group）， 0.23（ARTA medium-dose group） and 0.09（ARTA low-dose group）. CONCLUSIONS： ARTA can improve CIA model rats， and the effect tends to increase with the increase of dose. Above effect may be associated with reducing serum content of inflammatory factors and inhibiting the expression of FOS protein in synovial tissue.
ABSTRACT
Related substances in pharmaceutical formulations are associated with their safety, efficacy and stability. However, there is no overall study already published on the assessment of related substances in the Compound Ketoconazole and Clobetasol Propionate Cream. In this work, a reliable HPLC-TOF-MS qua-litative method was developed for the analysis of related substances in this preparation with a quick and easy extraction procedure. Besides the active pharmaceutical ingredients, two compounds named ke-toconazole impurity B′ optical isomer and ketoconazole impurity E were identified. Furthermore, a new HPLC method for qualitative and quantitative assessment on related substances and degradation pro-ducts, which were found in the stability test, was established and validated. The single standard to determine multi-components method was applied in the quantitative analysis, which was an effective way for reducing cost and improving accuracy. This study can provide a creative idea for routine analysis of quality control of the Compound Ketoconazole and Clobetasol Propionate Cream.
ABSTRACT
Objective To compare the size of target volume,amplitudes of movements in different directions,movement vector,dose to the diseased lung,whole lung volume,and setup error between free breathing fixation (method A) and four-dimensional computed tomography (4DCT)-guided abdominal balloon compression fixation (method B),and to demonstrate that the 4DCT-guided abdominal balloon compression fixation is effective in the treatment of non-small cell lung cancer (NSCLC).Methods A retrospective analysis was performed among 80 patients with NSCLC in our hospital.In those patients,40 received method A and 40 method B.The GTVfree and GTVpress were delineated on the maximum intensity projection (MIP) images of 10 respiratory phases using method A and method B,respectively.The PTVfree and PTVPress were obtained by expansion of the GTVfree and GTVpress,respectively.The paired t test was used to analyze the differences in the PTV,maximum amplitudes of movements in three dimensions,absolute value of the movement vector (|V|),and volume between method A and method B.The treatment planning system was used to compare the V5,V10,V20,and V30 of the diseased lung and the whole lung volume between method A and method B.All patients underwent cone-beam CT (CBCT) scans after positioning.Setup error was obtained by matching the CBCT images with the MIP images in the XVI system based on bone and grayscale values.Results The PTVfree and PTVpress were (283.2± 12.74) and (201.8± 12.99)cm3,respectively (P=0.002).The maximum amplitudes of movements in the right-left,superior-inferior,and anterior-posterior directions as well as thel V | value were (0.22±0.02),(1.85±0.08),(0.43±0.26),and (1.91±0.27) em,respectively,for method A,and (0.05±0.01),(0.41±0.03),(0.16±0.16),and (0.44±0.16) cm,respectively,for method B (P=0.120,0.001,0.070).The V5,V10,V20,and V30 for the diseased lung and total lung volume were (61.26± 4.27) ％,(44.52± 1.70) ％,(28.22± 3.13) ％,(18.26±5.17)％,and (3556±223.12) cm3,respectively,for method A,and (52.74±4.78)％,(38.76±4.92) ％,(23.71 ±4.03) ％,(15.54±3.43) ％,and (3376±311.65) cm3,respectively,for method B (P =0.001,0.003,0.004,0.021,0.004).There was no significant difference in setup error obtained by the XVI system between the two fixation methods (P＞0.05).Conclusions Without increasing setup error,abdominal balloon compression can effectively control the lung movement amplitude,reduce the planning target volume,and reduce the radiation dose to the lung in patients with NSCLC.

ABSTRACT
Objective The aim of this study was to investigate the anti-tumor effect on sequential injection of heterogeneic lymphocyte(HL)and autogeneic lymphocyte(AL). Methods The HL was prepared by using CC3HF1 mice as feeders. CB6F1 mice were used as recipients,and Hepa1-6 cells were inoculated into the recepients′groin subcutis. A cryoprecipitate was extracted from mouse plasma by freeze-thaw method to prepare fibrin Glue(FG);FG was combined with HL or AL to be FG-HL or FG-AL. The experimental treatment consisted of two stages. At first stage(15 d),FG-HL were injected on the surface of the tumor-bearing tissue of the recipients as the experimental group,and FG-phosphate buffer saline(FG-PBS)were injected on the surface of the tumor-bearing tissue of the rest recipients as the control group. The immunological factors such as tumor cell killing rate of the spleen lym-phocytes and numbers of lymphocytes,CD8 +T and NK in the two groups were detected,respectively. At later stage(10 d),a part of mice were randomly selected from the experimental and control groups,and the lymphocytes( AL) were used to form FG-AL,which were injected on the surface of tumor-bearing tissues in the rest of mice. Tumors in mice of the two groups were compared for tumor volume and tumor inhibition rate. Results The tumor cell killing rate of AL in the experimental group(26. 70 ± 7. 22) was signifi-cantly higher than that in the control group(5. 70 ± 2. 68)(P<0. 01). Numbers of mouse spleen lymphocytes,CD8 +T cells and NK cells were significantly higher than the corresponding values of the control group(P<0. 05). After the two-stage treatment,the aver-age tumor volume of the experimental group[(1.20 ±0.33)cm3]was significantly smaller than that of control group[(2.05 ±0.37) cm3](P<0. 01). The tumor inhibition rate in the experiment group was 41. 5% when compared to the control group. Conclusion Local injections of FG-HL followed by FG-AL can significantly inhibit the growth of transplanted tumor in mice;it is expected to become an anti-tumor biological therapy.
ABSTRACT
Objective To investigate the roles of cerebral metabolic rate for oxygen (CMRO2) monitoring in the evaluation of cerebral function after cardiopulmonary resuscitation (CPR) through transcranial doppler (TCD) and SjvO2. Methods In this prospective/retrospective analysis, we included 46 cases admitted to the general intensive care unit (GICU) of the Second Affiliated Hospital of Soochow University from January 2012 to December 2014. Upon admission, TCD and SjvO2 were performed,and the patients' characteristics were recorded. Based on the CPC score upon GICU discharge, the patients were divided into two groups with satisfactory cerebral function and poor cerebral function, respectively. Then the clinical symptoms, cerebral blood flow (CBF), a-vDO2, SjvO2 and CMRO2 were analyzed, followed by investigating their correlation with the prognosis of cerebral function. The measurement data that were normally distributed were presented by mean ± standard deviation. Student's t test was utilized for the inter-group comparison. Correlation analysis was performed. ROC was plotted, followed by evaluating roles of each index in the specificity and sensitivity of nervous prognosis. Results No statistical differences were noted in the gender, age, initial monitoring indicators, ICU duration and initial GCS between the two groups (P>0.05). The CA-ROSC time and APACHE II score in the satisfactory cerebral function group were significantly shorter than those of the poor cerebral function group (P<0.05). The SjvO2 in the satisfactory cerebral function group was significantly lower than that of the poor function group (67.33±10.30 vs. 76.89±13.08, t=-3.579, P<0.05). The Vs and Vd as revealed by TCD in the satisfactory function group were higher than those of the poor function group, together with the CBF. Significant decrease was noted in the PI and RI in the satisfactory function group compared with that of the poor function group (P<0.05). Besides, the CMRO2 and a-vDO2 in the satisfactory function group showed significant increase compared with those of the poor function group (P<0.05). ROC indicated that CMRO2, CBF, a-vDO2 and SjvO2 could be utilized for the evaluation of cerebral function, among which CMRO2 showed the highest accuracy for the cerebral function prognosis. Conclusions CMRO2, CBF, a-vDO2 and SjvO2 were associated with cerebral function prognosis. CMRO2 was the most appropriate parameter to evaluate the oxygen metabolism in brain tissues, which could evaluate the prognosis of cerebral function.
ABSTRACT
Objective To study the incidence,possible risk factors,and influence on patient outcomes of diaphragmatic dysfunction in patients after surgical treatment of type A aortic dissection using ultrasound.Methods Patients who received replacement of hemiarch or total arch with concomitant procedures concerning aortic pathology,and an elephant trunk procedure for the descending aorta were prospectively enrolled in this study from February to May 2017.After surgery,they were transferred to the cardiac surgical intensive care unit.They were divided into two groups based on diaphragmatic excursion:diaphragmatic dysfunction (DD) group and diaphragmatic function normal (DN) grouBilateral diaphragmatic excursions were evaluated using ultrasound during spontaneous breathing trial by T-tube.The differences in demographic characteristics,operation-related variables and outcomes were compared between the two groups.Results A total of 42 patients were enrolled in this study,and 32 of them suffered from diaphragmatic dysfunctions.Compared with DN group,the excursion of the influenced diaphragm in DD group was significantly reduced[(0.450 ± 0.331)cm vs.(1.801 ± 0.616)cm,P＜0.01],while the excursion of the non-influenced diaphragm was not reduced[(2.013±0.655)cm vs.(1.801 ±0.616) cm,P=0.254].Diaphragmatic thickness was comparable [(0.184±0.028)cm vs.(0.189±0.028)cm,P=0.559 ] between the two groups while thickening fraction was significantly reduced in DD group[(4.67％±3.63)％ vs.(23.58％±10.69)％,P＜0.01].Meanwhile,respiratory rate was significantly higher in DD group as compared to DN group [(24.13 ± 4.98)times/min vs.(20.50 ± 3.17)times/min,P=0.037].Patients in DD group showed longer cross-clamp duration[(121.78±27.75)min vs.(93.10±18.84)min,P=0.004] and longer cardiopulmonary bypass duration [(208.09±32.78)min vs.(182.70±24.38)min,P=0.03] than patients in DN grouFurthermore,binary logistic analysis indicated that longer cross-clamp duration was the potential risk factor for diaphragmatic dysfunction after type A aortic dissection surgery.Mechanical ventilation duration was longer in DD group than in DN group (88 h vs.37 h,P=0.194) but without statistical significance.The usage of noninvasive ventilation was significantly increased in DD group as compared to DN group (46.88％ vs.10％,P=0.036).Other outcomes such as post-operative complications,mortality,ICU length of stay were comparable between the two groups.Conclusions Diaphragmatic dysfunction was very common after surgical treatment of type A aortic dissection.Longer duration of cross-clamp was considered as a potential risk factor of diaphragmatic dysfunction.A sequential management of noninvasive ventilation after extubation was feasible for diaphragmatic dysfunction after surgical treatment of type A aortic dissection.

ABSTRACT
Objective To investigate the efficacy of dexmedetomidine on sedation in post-cardiac surgery patients with NIV intolerance.The changes of respiratory function and hemodynamics of the patients as well as non-invasive ventilation (NIV) failure rate were also under evaluation.Methods Thirty-five post-cardiac surgery patients with NIV intolerance and hypoxemia were enrolled in this prospective study.All patients were sedated with dexmedetomidine.NIV was standardized according to the uniform protocol.The main outcome was NIV success (avoiding endotracheal intubation) or NIV failure (requiring endotracheal intubation or die).The cardiorespiratory parameters (BP,HtR and RR) and artery blood gas analysis were prospectively recorded before and after sedation.The respiratory function and hemodynamics changes in both groups (NIV success group and NIV failure group) were then evaluated.Factors independently associated with NIV failure were identified using a logistic regression model.Results Twenty out of 35 patients (57.14％) survived while 15 (42.86％) patients failed NIV.After 1 h and 4 h of NIV with dexmedetomidine sedation,respiratory rate in both groups were decreased compared with baseline,especially in NIV success group.The PaO2/FiO2 was also improved after 1h and 4h of NIV treatment compared with baseline.The improvement was more significantly in NIV success group.The heart rate was decreased compared with baseline with no differences between two groups.There were no significant changes on PaCO2 and mean arterial pressure (MAP) during the treatment.The respiratory and hemodynamics variables identified as predictors of NIV failure were included in a multivariate logistic regression.RR ＞ 23 time/min (OR =3.2,95％ CI:2.043 ～ 4.301,P ＜ 0.01) 1 h after NIV,RR ＞ 20 time/min (OR =2.1,95％ CI:1.659～3.231,P=0.025) 4 h after NIV,PaO2/FiO2 ＜178 mmHg (OR=2.4,95％CI:1.892 ～ 3.287,P ＜0.01) 1 h after NIV and PaO2/FiO2 ＜ 185 mmHg (OR =1.7,95％ CI:1.243 ～ 2.365,P =0.041) 4 h after NIV independendy predicted NIV failure.Conclusions Dexmedetomidine might be considered as an effective and safe sedative for post-cardiac surgery patients with NIV intolerance.Early identification of predictors of NIV failure may facilitate early intervention.

Objective To investigate the characteristics of the bone marrow mesenchymal stem cell(MSC)in children with aplastic anemia(AA)in vitro,and the expressions of tumor necrosis factor -α-induced protein -8 -like 2(TIPE2)in the bone marrow,and the correlation between the level of TIPE2 mRNA with γ-interferon(IFN -γ)and IL -6 in AA patients.Methods Bone marrow samples were collected from 1 8 children with AA(AA group)and 8 children with bone injury (control group)who were hospitalized in Jinan Children′s Hospital from January 201 2 to June 201 5.MSC were isolated and cultured.The morphology of MSC was observed and immune phenotype was detected.The TIPE2 mRNA was detected by using real -time fluorescence quantitative PCR,and the levels of IFN -γand IL -6 were detected by using enzyme linked immunosorbent assay.Results Different sizes had been presented in the primi-tive MSC of AA patients,but the third passage MSC until 80% confluence had manifested the uniform convergence with long spindle and swirl distribution.In the sixth passage,cells showed degenerative change.The primitive and first pa-ssage MSC in patients with AA was longer than that in the controls.CD73 ,CD1 05 ,CD44 and CD90 were expressed in MSC,while CD34 ,CD45 ,CD271 expressed rarely.The level of TIPE2 mRNA in AA patients (5.29 ±1 .56)was obviously lower than that of the control group(8.68 ±2.00),and the difference was significant(t =-4.48,P 0.05).Conclusions The proliferation of MSC is significantly reduced in patients with AA.TIPE2,as an important role to stabilize the immune system,plays an important role in the occurrence of AA by its low expression and up -regula-ting the expression of inflammatory factors.
ABSTRACT
Objective To investigate the epidemiological characteristics and risk factors for healthcare-associated infection(HAI)in a newly built rehabilitation hospital.Methods A prospective survey was adopted to monitor HAI among all patients admitted to a newly built rehabilitation hospital between January 2011 and December 2014, related data were collected and analyzed statistically.Results A total of 22 126 patients (male,n=12 023;female, n=10 103)were monitored,age were 4 months-100 years old.HAI rate was 3.25%(n=720),HAI case rate was 3.34% (n=738).Patients in department of spinal rehabilitation had the highest HAI rate (9.76%);the main HAI site was lower respiratory tract (n = 388,52.57%);a total of 186 pathogenic isolates were detected,154 (82.80%)were gram-negative bacteria,25 (13.44%)were gram-positive bacteria,and 7 (3.76%)were fungi. Multivariate logistic regression analysis showed that paralysis (OR,1 .77 [95% CI ,1 .24 - 2.53 ]),length of hospital stay ≥60 days(OR,4.62 [95% CI ,3.28 -5.10]),age ≤ 10 years old (OR,1 .55 [95% CI ,1 .33 -2.93]),age ≥60 years old (OR,4.59 [95% CI ,1 .02-20.59]),chronic underlying diseases(OR,1 .56 [95% CI , 1 .37-11 .34]),invasive procedure (OR,3.33 [95% CI ,1 .21 -6.86]),and coma(OR,6.77 [95% CI ,5.41 -7.05])were major risk factors for HAI in patients in the rehabilitation hospital.Conclusion Investigation on newly built rehabilitation hospital is helpful for realizing the occurrence status of HAI,health care workers can carry out the corresponding prevention and control measures.
