Objective:To explorethe effect of acceptance and commitment therapy on self-disclosure, coping style and post-traumatic growth in patients with ovarian cancer undergoing chemotherapy after surgery.Methods:A total of 84 patients with ovarian cancer undergoing chemotherapy after surgery were recruited from the gynecology ward of the First Affiliated Hospital of University of Science and Technology of China for randomized controlled trial, from February 2022 to October 2022. All participants were divided into the intervention group and the control group with 42 patients in each group by random number table method. The patients in control group received routine care. The intervention group was given acceptance and commitment therapy (ACT) on the basis of the control group and intervened for three cycles of chemotherapy. The scores of Distress Disclosure Index (DDI), Cancer Coping Modes Questionnaire (CCMQ), and Post-Traumatic Growth Inventory (PTGI) were compared between the two groups before and after intervention.Results:There was no significant difference in the scores of DDI, CCMQ and PTGI between the two groups before intervention ( P>0.05). After intervention, DDI scorein intervention group was (38.81 ± 5.96) points, significantly higher than that in control group (34.43 ± 4.79) points, the difference was statistically significant ( t = 3.71, P<0.01). In terms of coping styles, after intervention, the scores of five dimensions of fantasy, resignation, avoidance, catharsis and confrontation were 6.00(6.00, 8.00), 9.00(8.00, 12.00), 9.00(8.75, 11.00), 7.00(6.00, 8.00) and 20.00(16.00, 21.00) points in the invention group, compared with the control group of 8.00(7.75, 9.00), 11.00(9.75, 13.00), 11.00(9.00, 13.00), 9.00(8.00, 12.00) and 16.00(13.00, 18.50) points, the differences were statistically significant ( Z = 2.86 to 5.11, all P<0.01). The total PTGI score in intervention group was (71.43 ± 8.68) points, significantly higher than that in control group(63.98 ± 6.92) points, the difference was statistically significant ( t = 4.35, P<0.01). Conclusions:ACT can increase self-disclosure, enhance positive coping, and promote post-traumatic growth in ovarian cancer patientsundergoing chemotherapy after surgery.

Investigation on the current situation of the development of intensive care units in Inner Mongolia Autonomous Region in 2022 / 中华危重病急救医学

OBJECTIVE@#To investigate the development present situation of the department of critical care medicine in Inner Mongolia Autonomous Region (hereinafter referred to as Inner Mongolia), in order to promote the standardized and homogeneous development of critical care medicine in Inner Mongolia, and also provide a reference for discipline construction and resource allocation.@*METHODS@#A survey study was conducted in comprehensive intensive care unit (ICU) of tertiary and secondary hospitals in Inner Mongolia by online questionnaire survey and telephone data verification. The questionnaire was based on the Guidelines for the Construction and Management of Intensive Care Units (Trial) (hereinafter referred to as the Guidelines) issued by the National Health Commission in 2009 and the development trend of the discipline. The questionnaire covered six aspects, including hospital basic information, ICU basic information, personnel allocation, medical quality management, technical skill and equipment configuration. The questionnaire was distributed in September 2022, and it was filled out by the discipline leaders or department heads of each hospital.@*RESULTS@#As of October 24, 2022, a total of 101 questionnaires had been distributed, 85 questionnaires had been recovered, and the questionnaire recovery rate had reached 84.16%, of which 71 valid questionnaires had been collected in a total of 71 comprehensive ICU. (1) There were noticeable regional differences in the distribution of comprehensive ICU in Inner Mongolia, with a relatively weak distribution in the east and west, and the overall distribution was uneven. The development of critical care medicine in Inner Mongolia was still lacking. (2) Basic information of hospitals: the population and economy restricted the development of ICU. The average number of comprehensive ICU beds in the western region was only half of that in the central region (beds: 39.0 vs. 86.0), and the average number of ICU beds in the eastern region was in the middle (83.6 beds), which was relatively uneven. (3) Basic information of ICU: among the 71 comprehensive ICU surveyed, there were 44 tertiary hospitals and 27 secondary hospitals. The ratio of ICU beds to total beds in tertiary hospitals was significantly lower than that in secondary hospitals [(1.59±0.81)% vs. (2.11±1.07)%, P < 0.05], which were significantly lower than the requirements of the Guidelines of 2%-8%. The utilization rate of ICU in tertiary and secondary hospitals [(63.63±22.40)% and (44.65±20.66)%, P < 0.01] were both lower than the bed utilization rate required by the Guidelines (75% should be appropriate). (4) Staffing of ICU: there were 376 doctors and 1 117 nurses in tertiary hospitals, while secondary hospitals had 122 doctors and 331 nurses. There were significant differences in the composition ratio of the titles of doctors, the degree of doctors, and the titles of nurses between tertiary and secondary hospitals (all P < 0.05). Most of the doctors in tertiary hospitals had intermediate titles (attending physicians accounted for 41.49%), while most of the doctors in secondary hospitals had junior titles (resident physicians accounted for 43.44%). The education level of doctors in tertiary hospitals was generally higher than that in secondary hospitals (doctors: 2.13% vs. 0, masters: 37.24% vs. 8.20%). The proportion of nurses in tertiary hospitals was significantly lower than that in secondary hospitals (17.01% vs. 24.47%). The ratio of ICU doctors/ICU beds [(0.64±0.27)%, (0.59±0.34)%] and ICU nurses/ICU beds [(1.76±0.56)%, (1.51±0.48)%] in tertiary and secondary hospitals all failed to meet the requirements above 0.8 : 1 and 3 : 1 of the Guidelines. (5) Medical quality management of ICU: compared with secondary hospitals, the proportion of one-to-one drug-resistant bacteria care in tertiary hospitals (65.91% vs. 40.74%), multimodal analgesia and sedation (90.91% vs. 66.67%), and personal digital assistant (PDA) barcode scanning (43.18% vs. 14.81%) were significantly higher (all P < 0.05). (6) Technical skills of ICU: in terms of technical skills, the proportion of bronchoscopy, blood purification, jejunal nutrition tube placement and bedside ultrasound projects carried out in tertiary hospitals were higher than those in secondary hospitals (84.09% vs. 48.15%, 88.64% vs. 48.15%, 61.36% vs. 55.56%, 88.64% vs. 70.37%, all P < 0.05). Among them, the placement of jejunal nutrition tube, bedside ultrasound and extracorporeal membrane oxygenation were mainly completed independently in tertiary hospitals, while those in secondary hospitals tended to be completed in cooperation. (7) Equipment configuration of ICU: in terms of basic equipment, the ratio of the total number of ventilators/ICU beds in tertiary and secondary hospitals [0.77% (0.53%, 1.07%), 0.88% (0.63%, 1.38%)], and the ratio of injection pump/ICU beds [1.70% (1.00%, 2.56%), 1.25% (0.75%, 1.88%)] didn't meet the requirements of the Guidelines. The equipment ratio was insuffcient, which means that the basic needs of development had not been met yet.@*CONCLUSIONS@#The development of comprehensive ICU in Inner Mongolia has tended to mature, but there is still a certain gap in the development scale, personnel ratio and instruments and equipment compared with the Guidelines. Moreover, the comprehensive ICU appears the characteristics of relatively weak eastern and western regions, and the overall distribution is uneven. Therefore, it is necessary to increase efforts to invest in the construction of the department of critical care medicine.

Research progress of mechanisms of oxidative stress in septic cardiomyopathy / 中华危重病急救医学

Sepsis is currently defined as a life-threatening multiple organ dysfunction caused by host dysregulated response to infection, with high morbidity and mortality in intensive care units. Patients with sepsis are often complicated with cardiac dysfunction known as septic cardiomyopathy (SCM). The occurrence of SCM is related to the high mortality of patients, which has been closely concerned for a long time, and is also one of the challenges to be solved in the systematic treatment of sepsis. A large number of studies have shown that oxidative stress contributes to the pathogenesis of SCM. The role of oxidative stress in SCM and the potential treatment measures for redox imbalance are discussed in this paper.

Resilience partially mediated the relationship between hope trait and empathy, the mediating effect of resilience was 0.38. Conclusions:Managers should pay attention to the cultivation of midwives′ hope traits and psychological resilience, and actively improve the midwives′ psychological quality, so as to effectively improve the empathy ability and establish a harmonious and high-quality nurse patient relationship.

Predictive value of CT texture analysis for recurrence in children with acute pancreatitis / 中华消化外科杂志

Objective:To explore the predictive value of computed tomography (CT) texture analysis for the recurrence in children with acute pancreatitis (AP).Methods:The clinical diagnostic test was conducted. The clinical data of 56 children with primary AP who were admitted to Wuhan Fourth Hospital from January 2016 to January 2018 were collected. There were 13 males and 43 females, aged from 3.5 to 13.0 years, with a median age of 5.5 years. Based on follow-up in other hospitals, 20 children with recurrence of AP were allocated into recurrence group, and 36 children without recurrence were allocated into non-recurrence group. All the 56 children underwent abdomen plain and enhanced CT scan within 24 hours after first admission. Observation indicators: (1) comparison of clinicopathological features between two groups of children with AP. (2) comparison of CT texture parameters between two groups of children with AP. (3) diagnostic efficacy of clinical features and CT texture parameters. Follow-up using outpatient reexamination and telephone interview was conducted to detect recurrence of AP up to February 2020. The duration of follow-up required more than or equal to 24 months. The Shapiro Wilk test was used to analyze normality of measurement data. Measurement data with normal distribution were repre-sented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M (range) or M ( P25, P75), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was analyzed using the chi-square test. Comparison of ordinal data was conducted using the Mann-Whitney U test. Clinical parameters and CT texture parameters with statistical differences were multivariate analyzed using the Logistic regression model. Receiver operating characteristic curve (ROC) analysis was used to evaluate the predictive efficacy of parameters for recurrence of AP. Results:(1) Comparison of clinicopatholo-gical features between two groups of children with AP: cases with or without complications were 14 and 6 for the recurrence group, versus 7 and 29 for the non-recurrence group, showing a significant difference between the two groups ( χ2=14.021, P<0.05). Cases with minimal, moderately severe or severe disease (severity of disease) were 2, 5, 13 for the recurrence group, versus 19, 11, 6 for the non-recurrence group, showing a significant difference between the two groups ( Z=5.414, P<0.05). (2) Comparison of CT texture parameters between two groups of children with AP: the energy value in the arterial phase on CT examination was 0.186(0.174,0.206)for the recurrence group and 0.413(0.405,0.425) for the non-recurrence group, showing a significant difference between the two groups ( Z=9.413, P<0.05). The energy value and entropy value in the venous phase on CT examination were 0.084(0.078,0.092) and 0.961(0.210,1.720) for the recurrence group, versus 0.135(0.124,0.156) and 0.372(0.210,0.535) for the non-recurrence group, showing significant differences between the two groups ( Z=4.763, 7.243, P<0.05). (3) Diagnostic efficacy of clinical parameters and CT texture parameters: results of multivariate analysis showed the complications, severity of disease, energy value in the arterial phase on CT examination were related factors for recurrence in children with AP, energy value and entropy value in the venous phase on CT examination were related factor for recurrence in children with AP ( odds ratio=0.874, 0.765, 0.837, 0.902, 0.813, 95% confidence interval as 0.802?0.985, 0.581?0.914, 0.753?0.897, 0.862?0.948, 0.765?0.873, P<0.05). Results of ROC analysis showed that that areas under curve (AUC) of complications, severity of disease in the clinical parameters were 0.734 and 0.832, the AUC of single CT texture parameter was 0.811?0.867, the AUC of clinico-pathological parameters combined with CT texture parameters was 0.882. Conclusion:CT texture analysis can early and non-invasively predict the recurrence of AP in children, and the combination of clinicopathological parameters with CT texture parameter has a better predictive efficacy.

Study on a multidisciplinary continuing management model for hospitalized elderly patients with multimorbidity / 中华老年医学杂志

Objective:To construct a multidisciplinary continuing management model for hospitalized elderly patients with multimorbidity and to assess the effectiveness of this model, thus providing insights and suggestions for the management of elderly patients with co-morbidity.Methods:This was a prospective randomized controlled study.Patients with comorbidity admitted to the geriatric ward of our hospital from November 2015 to July 2017 were selected and received comprehensive geriatric assessment(CGA). Patients were randomly divided into the intervention group receiving continuous multidisciplinary medical treatment and the control group receiving conventional medical treatment.The work flow and characteristics of the intervention group were examined, and the effectiveness of the two models(including cost of hospitalization, duration, patient satisfaction, patient functional status, adverse events, and changes in healthy behavior awareness after 6 months of follow-up)were compared between the two groups.Results:A total of 440 patients with comorbidity were included in the study, with an average age of(76.0±8.1)years, including 226 in the intervention group and 214 in the control group.After multidisciplinary continuing medical intervention, patients in the intervention group were associated with a significantly higher level of satisfaction on physician availability(86.3% vs.74.8%, χ2=9.354, P=0.002), medical care(99.6%vs.86.7%, χ2=4.926, P=0.026)and nursing quality(93.4%vs.86.4%, χ2=5.829, P=0.016), compared with the control group.After 6 months of follow-up, the probability of adverse events in the intervention group was lower than that in the control group(61.1%vs.73.5%, χ2=7.436, P=0.006), and drug-related adverse reactions/events in the intervention group(9.0%vs.22.1%, χ2=13.858, P<0.000)were significantly lower than those in the control group.Furthermore, the proportion of patients with improved healthy behavior awareness was markedly higher in the intervention group than that in the control group(30.3%vs.5.4%, χ2=43.979, P<0.001). Conclusions:The multidisciplinary hospital-community continuity management model with CGA at the core can reduce the occurrence of adverse events, improve patient satisfaction and healthy behavior awareness, and is a worthy exploration of a new medical model for elderly comorbid patients.

Stratified outcomes of "Kidney Disease: Improving Global Outcomes" serum creatinine criteria in critical ill patients: a secondary analysis of a multicenter prospective study / 中华危重病急救医学

Objective:To investigate the different outcomes of two types of acute kidney injury (AKI) according to standard of Kidney Disease: Improving Global Outcomes-AKI (KDIGO-AKI), and to analyze the risk factors that affect the prognosis of intensive care unit (ICU) patients in China.Methods:A secondary analysis was performed on the database of a previous study conducted by China Critical Care Clinical Trial Group (CCCCTG), which was a multicenter prospective study involving 3 063 patients in 22 tertiary ICUs in 19 provinces and autonomous regions of China. The demographic data, scores reflecting severity of illness, laboratory findings, intervention during ICU stay were extracted. All patients were divided into pure AKI (PAKI) and acute on chronic kidney disease (AoCKD). PAKI was defined as meeting the serum creatinine (SCr) standard of KDIGO-AKI (KDIGO-AKI SCr) and the estimated glomerular filtration rate (eGFR) at baseline was ≥ 60 mL·min -1·1.73 m -2, and AoCKD was defined as meeting the KDIGO-AKI SCr standard and baseline eGFR was 15-59 mL·min -1·1.73 m -2. All-cause mortality in ICU within 28 days was the primary outcome, while the length of ICU stay and renal replacement therapy (RRT) were the secondary outcome. The differences in baseline data and outcomes between the two groups were compared. The cumulative survival rate of ICU within 28 days was analyzed by Kaplan-Meier survival curve, and the risk factors of ICU death within 28 days were screened by Cox multivariate analysis. Results:Of the 3 063 patients, 1 042 were enrolled, 345 with AKI, 697 without AKI. The AKI incidence was 33.11%, while ICU mortality within 28 days of AKI patients was 13.91% (48/345). Compared with PAKI patients ( n = 322), AoCKD patients ( n = 23) were older [years old: 74 (59, 77) vs. 58 (41, 72)] and more critical when entering ICU [acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score: 23 (19, 27) vs. 15 (11, 22)], had worse basic renal function [eGFR (mL·min -1·1.73 m -2): 49 (38, 54) vs. 115 (94, 136)], more basic complications [Charlson comorbidity index (CCI): 3 (2, 4) vs. 0 (0, 1)] and higher SCr during ICU stay [peak SCr for diagnosis of AKI (μmol/L): 412 (280, 515) vs. 176 (124, 340), all P < 0.01]. The mortality and RRT incidence within 28 days in ICU of AoCKD patients were significantly higher than those of PAKI patients [39.13% (9/23) vs. 12.11% (39/322), 26.09% (6/23) vs. 4.04% (13/322), both P < 0.01], while no significant difference was found in the length of ICU stay. Kaplan-Meier survival curve analysis showed that the 28-day cumulative survival rate in ICU in AoCKD patients was significantly lower than PAKI patients (Log-Rank: χ2 = 5.939, P = 0.015). Multivariate Cox regression analysis showed that admission to ICU due to respiratory failure [hazard ratio ( HR) = 4.458, 95% confidence interval (95% CI) was 1.141-17.413, P = 0.032], vasoactive agents treatment in ICU ( HR = 5.181, 95% CI was 2.033-13.199, P = 0.001), and AoCKD ( HR = 5.377, 95% CI was 1.303-22.186, P = 0.020) were independent risk factors for ICU death within 28 days. Conclusion:Further detailed classification (PAKI, AoCKD) based on KDIGO-AKI SCr standard combined with eGFR is related to ICU mortality in critical patients within 28 days.

Clinical significance and correlation of serum AFP, ALP, PIVKA-Ⅱ in patients with primary liver cancer / 中国基层医药

Objective:To investigate the clinical significance and correlation of serum alpha fetoprotein(AFP), alkaline phosphatase (ALP), and protein induced by vitamin K antagonist-Ⅱ(PIVKA-Ⅱ) in patients with primary hepatoculellar carrcinoma (PHC).Methods:A total of 72 patients with PHC who admitted to Dajiangdong Hospital from May 2017 to June 2019 were selected as observation group and they were divided into metastasis group (25 cases) and non-metastasis group (47 cases) according to the presence or absence of lymph node metastasis.Another 72 healthy people who had physical examinations during the same period were selected as the control group.The serum levels of AFP, ALP and PIVKA-Ⅱ were measured in all patients.ROC curves were used to analyze the clinical value of these three indicators in the early diagnosis and prognosis of PHC.The correlation between serum AFP, ALP, PIVKA-Ⅱ levels and clinical stage of PHC was analyzed by Pearson method.Results:The serum levels of AFP, ALP and PIVKA-Ⅱ in the observation group were significantly higher than those in the control group( t=36.64, 24.53, 47.89, P=0.012, 0.005, 0.001). The serum AFP, ALP and PIVKA-Ⅱ levels were higher in the metastasis group than in the non-metastatic group( t=20.98, 38.12, 54.17, P=0.04, 0.001, 0.000). ROC analysis showed that the serum AFP, ALP and PIVKA-Ⅱ had diagnostic value for PHC, and the combined detection had higher diagnostic efficacy ( P=0.021, 0.014, 0.003, 0.001). Compared with single index, the clinical value of three indicators in predicting whether PHC had lymph node metastasis increased significantly( P=0.036, 0.027, 0.018, 0.005). The specificity(89.57%), sensitivity(92.60%), positive predictive value(89.53%) and negative predictive value(83.75%) of the three indicators in detecting PHC increased significantly( P<0.05). Pearson analysis showed positive correlations between serum AFP, ALP, PIVKA-Ⅱ and tumor stage( P<0.05). Conclusion:Serum AFP, ALP and PIVKA-Ⅱ have certain clinical value in the early diagnosis of PHC, and the combination of these three indicators can improve the diagnostic efficacy.

Investigation of the status and influencing factors of optimistic coping among gynecologic tumor patients / 中国实用护理杂志

Objective:To explore the status and influencing factors of optimistic coping among gynecologic tumor patients.Methods:A total of 401 cases of gynecologic tumor patients was selected by the convenient sampling method. They were investigated by the Jalowiec Coping Scale, The Eysenck Personality Questionnaire-Revised Short Scale for Chinese, General Self-Efficacy Scale, Social Support Rating Scale.Results:Optimistic coping in gynecologic tumor patients scored (1.61±0.36). The main influencing factors included residence place, education level, general self-efficacy score, personality trait score, they could explain 25.2% variation of optimistic coping of gynecological tumor patients.Conclusions:Optimistic coping in gynecologic tumor patients scored is at a low level. Residence and education level, general self-efficacy score and personality trait score are important factors that affect the level of optimistic coping in gynecologic tumor inpatients. Medical staff should develop targeted nursing intervention measures, pay attention to mining and shaping patients' positive and optimistic personality traits, in order to improve patients' optimistic coping level, to achieve the ultimate goal of improving patients' quality of life nursing.

Cypermethrin induces cell injury in primary cortical neurons of C57BL/6 mice by inhibiting Nrf2/ARE signaling pathway / 南方医科大学学报

OBJECTIVE@#To study the role of Nrf2/ARE signaling pathway in cypermethrin-induced oxidative stress and apoptosis of cerebral cortex neurons in C57BL/6 mice.@*METHODS@#The cortical neurons of C57BL/6 mice were cultured and identified, and a cypermethrin-induced cell injury model was established by treating the cells with 0, 25, 50 and 100 μmol/L of cypermethrin for 48 h. CCK-8 assay was used to analyze the effects of cypermethrin on the cell viability, and the fluorescence probe DCFH-DA was used for detecting intracellular reactive oxygen species (ROS); flow cytometry was performed for determining the apoptosis rate of the cells. The mRNA and protein expression levels of Nrf2 and its downstream genes HO-1 and NQO1 were detected using qPCR and Western blotting.@*RESULTS@#Exposure to cypermethrin at different doses inhibited the viability of the cultured cortical neurons. With the increase of cypermethrin dose, the viability of the neurons decreased progressively, the intracellular ROS and the cell apoptosis rate increased, and the neuronal injury worsened. At the dose of 50 and 100 μmol/L, cypermethrin significantly down-regulated the expressions of HO-1, NQO1 and Nrf2 at both the mRNA and protein levels in the cells ( < 0.01).@*CONCLUSIONS@#Cypermethrin exposure shows a dose-dependent neurotoxicity by inhibiting Nrf2/ARE signaling pathway, down-regulating the expression of Nrf2 and its downstream genes HO-1, NQO1 mRNA and protein, and inducing oxidative damage and apoptosis in primary mouse cortical neurons, .

Objective@#To investigate the clinical significance of combined examinations for neutrophil-lymphocyte ratio (NLR), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR) and fecal occult blood (OB) in the differential diagnosis of Crohn′s disease and irritable bowel syndrome. @*Methods@#A total of 129 patients with Crohn′s disease and 120 patients with irritable bowel syndrome from October 2014 to October 2017 in Changhai Hospital were enrolled in this study. The results of NLR, CRP, ESR and OB were recorded. Logistic regression was used to study the association of the four indicators. The combined impact of the four indicators was explored with multivariable regression. ROC curve was used to compare the diagnostic value of the combined examinations with the four indicators for Crohn′s disease. The diagnosis was performed by substituting the data of individual patient into regression model. @*Results@#The levels of NLR, CRP, ESR and OB in Crohn′s disease group were higher than those in irritable bowel syndrome group (Z=-7.067--4.148, P＜0.01). The area under the curve of combined diagnostic indicator was 0.881, which was higher than that of single NLR, CRP, ESR or OB (0.759, 0.695, 0.652, 0.643) respectively (Z=3.19-5.60, P＜0.01). When the cutoff value was 0.498, the sensitivity was 79.1%, the specificity was 83.3% and the diagnostic accuracy was 81.1%. A patient who was not included within the statistical range of this experimental study was randomly assigned to the model and 0.831 of P value was obtained, which was higher than the cutoff value of 0.498, indicating that the patient suffered from Crohn′s disease with accuracy of 81.1%. @*Conclusion@#The logistic regression model established with the combined diagnostic indicators, which was formulated by examinations of NLR, CRP, ESR and OB, exhibited higher diagnostic value than any single indicator in the differential diagnosis of Crohn′s disease and irritable bowel syndrome.

Self-Compassion and Confucian Coping as a Predictor of Depression and Anxiety in Impoverished Chinese Undergraduates.

The ability of self-compassion and Confucian coping to predict anxiety and depression were examined in impoverished Chinese undergraduate students. Three hundred and thirty impoverished undergraduates completed measures of self-compassion, Confucian coping, depression, and anxiety. Results showed that higher self-compassion predicted lower depression and anxiety in impoverished undergraduates. Higher pro-setback thinking and responsibility thinking of Confucian coping were related with lower depression and anxiety. Higher fate thinking of Confucian coping was related with higher depression and anxiety. The predictive ability for depression and anxiety of self-compassion combined with fate thinking was better than self-compassion alone. Intervention to enhance self-compassion and reduce fate thinking may be beneficial to mental health in impoverished undergraduates.

High throughput-targeted sequencing panel for exploring radiosensitivity associated genes in esophageal squamous cell carcinoma / 中华肿瘤杂志

Objective@#To explore radiosensitivity-associated genes in esophageal squamous cell carcinoma by targeted sequencing panel.@*Methods@#The peripheral blood from 22 esophageal squamous cell carcinoma (ESCC) patients received radiotherapy alone were collected, respectively. The genomic DNA (gDNA) of peripheral blood was extracted and used to create a library of gDNA restriction fragments. The gDNA restriction fragments were hybridized to the HaloPlex probe capture library, which comprises 356 cancer genes selected from the Catalogue of Somatic Mutations in Cancer (Cosmic) database of 2011 updated edition. The sequencing data were aligned by the Genome Analysis Toolkit GATK (version 3.0) and Picar. The single nucleotide polymorphism and inserted-deletion (SNP/InDel) variations were annotated by online database. The pathway enrichment was analyzed by Ingenuity Pathway analysis (IPA). Moreover, according to the short-period curative effect, 22 patients were divided into two groups: the radiation- sensitivity group (CR+ PR) and the radiation-resistant group (PD+ SD). The nonsynonymous mutation sites were statistically analyzed and the genes associated with radiosensitivity of ESCC were screened.@*Results@#More than 97% sequencing reads were aligned to human genome reference sequence and more than 90% sequencing reads were the target sequences. SNP/InDel database annotation results showed that the mutations of 22 cases mainly distributed in exons, and the mutant types were mainly missense and synonymous single nucleotide variant (SNV). There were 23 genes of high-frequency mutation associated with esophageal cancer. Pathway enrichment by IPA showed that 3 pathways were associated with the development of esophageal cancer, which were roles of BRCA1 in DNA damage response pathway, DNA double-strand break repair by non-homologous end joining pathway and ATM signaling pathway. According to the curative effect, five genes including mismatch repair system component (PMS1), fibronectin 1(FN1), mutL homolog 1 (MLH1), B-Raf proto-oncogene, serine/threonine kinase (BRAF), patched 1 (PTCH1) and cytochrome P450 family 2 subfamily C member 19 (CYP2C19) were associated with radiosensitivity of ESCC patients.Moreover, the PTCH1 was mutated in all of 22 ESCC patients, while the variations of rs199476092 and rs202111971 sites of PTCH1 were only identified in the radiation-resistant group.@*Conclusions@#We find that the variations of rs199476092 and rs202111971 in the encoding region of PTCH1 gene are significantly associated with radiosensitivity of ESCC patients.

Ulinastatin attenuates lipopolysaccharide-induced acute lung injury by intervening p38 MAPK/ERK signaling pathway / 中国药理学通报

Aim To investigate whether ulinastatin has a beneficial effect on lipopolysaccharide( LPS) induced acute respiratory distress syndrome ( ARDS ) in rats, and to explore the possible underlying mechanisms. Methods Fifty-six Wistar rats were randomly as-signed into control group, model group( LPS 6,12,24 h groups), ulinastatin group(UTI 6,12,24 h groups), with 8 in each group. ARDS rat model was reproduced by intraperitoneal injection of LPS ( 10 mg · kg-1 ) , The rats in UTI groups were injected ulinastatin (20 000 u·kg-1), The rats in the control group re-ceived an equal volume of normal saline at the same time, rats in each group were sacrificed at 6,12,24 hours after LPS challenge. Plasma and lung tissue sam-ples were collected, Histopathological evaluation, lung wet/dry (W/D) ratio, Tumor necrosis factor-a(TNF-α) , Interleukin-18 ( IL-18 ) , surfactant protein A ( SPA) , malondialdehyde ( MDA ) , nitric oxide ( NO ) and superoxide dismutase( SOD) were analyzed. Immu-nohistochemical method was performed to detect the protein expression of p38MAPK and ERK. Western blot method was used to detect lung phosphorylated p38 MAPK ( p-p38 MAPK ) and pERK protein expres-sion changes. Result In the control groups, lung tis-sue showed a normal structure and clear pulmonary al-veoli under a light microscope. In the model group, ARDS characters such as extensive thickening of the alveolar wall, significant infiltration of inflammatory cells, demolished structure of pulmonary alveoli, and hemorrhage were found. In the all UTI treatment groups, these pathological changes in lung were markedly alleviated compared with those of LPS-in-duced ARDS group. Compared with control groups, lung W/D ratio, tumor necrosis factor-a ( TNF-α) , in-terleukin-18 ( IL-18 ) and surfactant protein A ( SPA ) in plasma ,and lung MDA,NO levels in lung homogenates in the LPS group were increased significantly, while the lung SOD levels in the LPS group were decreased. Compared with the LPS group, lung W/D ratio, TNF-aIL-18 and ( SPAin plasma , and lung MDA levels in lung homogenates in the UTI groups were decreased significantly, while the lung SOD levels in the UTI groups were increased. Immunohistochemistry showed that positive expressions of p38 MAPK and ERK in cy-toplasm and nucleus in the ulinastatin treatment groups were significantly lower than those in the model group. Western blot showed that compared with the control group, the p-p38MAPK and pERK protein expression in LPS group were significantly increased, and the uli-nastatin could inhibit the protein expressions compared with model group. Conclusion Ulinastatin can signifi-cantly ameliorate the lung injury induced by LPS in rats via the intervention of p38 MAPK and ERK signa-ling pathway and reducing inflammation and antioxidant effect.

Study on effect of voltage-gated calcium channel protein in meridian tissue cells exciting conduction / 中国针灸

<p><b>OBJECTIVE</b>To explore the material basis of conduction along meridian.</p><p><b>METHODS</b>Sixty SD rats(30 males,30 females) were randomly assigned into a normal group,an acupuncture group,a verapamil blocking group and a 0.9%NaCl blocking group(control group),15 rats in each one. Fluo 3-AM(calcium fluorescence probe) was injected at the observation part in femoral stomach meridian of foot-(meridian part) and the approaching femoral meridian part(non-meridian part) in the normal group and the acupuncture group,and then incubation was applied. In the verapamil blocking group,verapamil was injected at local meridian part and non-meridian part,and in the control group 0.9%NaCl was injected. Then Fluo 3-AM was injected at the meridian part and non-meridian part in the two groups,and incubation was implemented. Caimaging changes in cells were recorded for more than 20 min after injection of every part in each group respectively. After the above operations in the last three groups,acupuncture was used at "Zusanli"(ST 36) immediately,with electroacupuncture for one min,then Caimaging changes in cells at the meridian and non-meridian parts were recorded for more than 20 min.</p><p><b>RESULTS</b>In the normal group, Cafluorescence intensity at the meridian part was higher than that at the non-meridian part. In the acupuncture group,after acupuncture Cafluorescence intensity at the meridian part was obviously higher than before,but the change before and after acupuncture was not apparent at the non-meridian part. After verapamil blocking local calcium channel and acupuncture,the Cafluorescence of the meridian part did not strengthen,and the change of that before and after acupuncture at the non-meridian part was not obvious. In the control group,after injecting 0.9%NaCl at local part,Cafluorescence intensities of the meridian and non-meridian parts showed no obvious change,so was that before and after acupuncture.</p><p><b>CONCLUSIONS</b>The voltage-gated calcium channel at the meridian part is highly correlated with its tissue cells exciting conduction.</p>
