In our gastroenterology clinic from Jun. 2008 to Jan. 2009, 20. 9% (277/1320) patients were diagnosed with functional dyspepsia (FD) and 14. 8% (41/277) of them with psychological problems according to Minnesota Multiphasic Personality Inventory (MMPI). In those with psychological disorders,92.7% were found with somatization, 60. 9% with depression and anxiety, 97.6% with abdominal pain,75.6% with bloating, 63.4% with early fullness and 36. 6% with nausea. More than 80% patients with anxiety and depression complained irritability, worry, fatigue, poor concentration, memory loss and insomni.a. After 4 weeks of psychological consultation and anti-depression treatment, 5 patients had significant improvement, 31 had improvement and 3 had no response. The overall response rate was 87. 8%.In summary,there is a high prevalence of depression and anxiety in population with FD. Hypochondria and somatization are common among these patients. Psychological consultation with anxiolytic drugs may have good therapeutic effects.

Background and purpose:Drug resistance is a major cause of failure in lung cancer chemotherapy. This study aimed to investigate the effect of YAP on doxorubicin resistance in lung cancer and its underlying mechanism. Methods:Doxorubicin resistant lung cancer cell clones were established from parental sensitive cancer PC9 cell line via in vitroinduction, and the expression of YAP was analyzed. YAP was down-regulated via shRNA to different levels. MTS assay was employed to determine cell proliferation and drug sensitivity. Flow cytometry was used to determine cell cycle distribution, apoptosis and uptake of Rh-123. Western blot and quantitative real-time polymerase chain reaction (QRT-PCR) assay were used to determine the expression of ABCB1, ABCC1, p53, Runx2, ITGB2 and ErbB4. The phosphory-lation of serine/threonine kinase (AKT) was determined as well.Results:Doxorubicin resistant PC9/Adr cell clone was obtained with over-expressed YAP. Expression of YAP in PC9/Adr cells was down-regulated to different levels via shR-NA. After YAP silencing, cell proliferation was reduced, while sensitivity to doxorubicin was increased. The cell cycle was significantly halted by G0/G1 phase. Doxorubicin induced-apoptotic rate and cellular uptake of Rh-123 were increased,with positive correlation to YAP silencing level. Western blot and QRT-PCR results showed that after YAP silencing, ABCB1, ABCC1, Runx2, ITGB2, and ErbB4 proteins were down-regulated, while the expression of p53 was up-regulated. Phosphorylation of AKT was inhibited as well.Conclusion:Over-expression of YAP is involved in doxorubicin resistance in PC9/Adr cell line. Silencing of YAP could restore doxorubicin sensitivity. The mechanism involves regulation of drug resistance-related genes and promotion of apoptosis.

Background and objective It has been proven that circular RNAs (circRNAs) play an important role on the process of many types cancer and circUBAP2 was a cancer-promoting circRNA,however,the role and mechanism in lung cancer was not clear.The aim of this study is to investigate the effects of circUBAP2 on cell proliferation and invasion of human lung cancer A549 cells.Methods CCK-8 assay was employed to detect the effect of circUBAP2 sliencing on cell proliferation ofA549 cells.Fow cytometry was applied to detect the impact of circUBAP2 siiencing on cell cycle and cell anoikis,and Transwell invasion assay was applied to determine cell invasion ofA549 cells.We also employed Western blot and Real-time PCR to determine the expressions of CDK6,cyclin D1,p27 and c-IAP1,Bcl-2,Survivin,Bax,FAK,Rac1 and MMP2,and the activities of JNK and ERK1/2,luciferase report gene assay was used to detect the targets.Results CCK-8 assay showed that the inhibition of cell proliferation in the circUBAP2-siRNA group compared to untreated group and siRNA control group.Results of cell cycle detected by flow cytometry showed that cell cycle arrestd at G0/G1 after circUBAP2 silencing,cell apoptosis rate increased also.We also found that after circUBAP2 silencing,cell invasion of A549 cells was significantly inhibited.Western blot and Real-time P CR results showed that expression of CDK6,cyclin D 1,c-IAP1,Bcl-2,Survivin,FAK,Rac 1 and MMP2 were down-regulated,and the expression of p27 and Bax were up-regulated.Moreover,the activities of JNK and ERK1/2 were inhibited because of circUBAP2 silencing,the target genes were miR-339-5p,miR-96-3p and miR-135b-3p.Conclusion CircUBAP2 plays an important role in the proliferation and invasion of human lung cancer.Silencing of circUBAP2 might be a novel target for molecular targeted therapy of patients with lung cancer.

Objective To investigate the level of innovation ability and learning proactivity in nursing students, and to analyze the correlation between them. Methods A total of 260 grade 2010—2013 nursing students were recruited in this study by random sampling method. They were investigated with the test of self innovation level scale and learning proactivity scale. Results The average score of innovation ability was (63. 04 ± 10. 99), and the average score of learning proactivity was (72. 96 ± 6. 17) in nursing students;the male nursing students in learning driving force dimension was significantly higher than that of the female nursing students (P<0. 05); the rural students in learning initiative and learning objective dimension score were significantly higher than those of urban students as well as learning driving force (P<0. 05). Students with high innovation had higher total learning initiative scores, learning goals, learning control and solid learning dimension than students with low innovation ability (P <0. 05). The innovation ability of nursing students had significantly positive correlation with learning initiative score and learning goals, learning control and solid learning three dimensions (r=0. 272,0. 153,0. 243,0. 398;P <0. 05). Conclusions It is suggested to pay attention to improving learning proactivity of nursing students, which contributes to innovation ability.

Tumor-associated macrophages (TAMs) mostly exhibit M2-like (alternatively activated) properties and play positive roles in angiogenesis and tumorigenesis. Vascular endothelial growth factor (VEGF) is a key angiogenic factor. During tumor development, TAMs secrete VEGF and other factors to promote angiogenesis; thus, anti-treatment against TAMs and VEGF can repress cancer development, which has been demonstrated in clinical trials and on an experimental level. In the present work, we show that miR-150 is an oncomir because of its promotional effect on VEGF. MiR-150 targets TAMs to up-regulate their secretion of VEGF in vitro. With the utilization of cell-derived vesicles, named microvesicles (MVs), we transferred antisense RNA targeted to miR-150 into mice and found that the neutralization of miR-150 down-regulates miR-150 and VEGF levels in vivo and attenuates angiogenesis. Therefore, we proposed the therapeutic potential of neutralizing miR-150 to treat cancer and demonstrated a novel, natural, microvesicle-based method for the transfer of nucleic acids.

Objective:To evaluate the relationship between the occipitocervical angle(basilar vertebral angle [O-C 2 angle], mento-pharyngeal angle [M-P angle], and cervical range of motion [CROM]) and difficult airway after occipitocervical fusion surgery in the patients. Methods:This was a retrospective study. The clinical data from patients who underwent occipitocervical fusion surgery at our hospital from March 2018 to March 2023 were retrospectively collected. Preoperative and last follow-up airway assessment data and cervical lateral X-rays were collected to measure the O-C 2 angle, M-P angle and CROM. Patients were divided into negative group (Mallampati grade Ⅰ or Ⅱ, suggesting no difficulty in intubation) and positive group (Mallampati grade Ⅲ or Ⅳ, suggesting possible difficulty in intubation) based on the last follow-up modified Mallampati classification. Results:A total of 53 patients were finally included, with 18 cases in positive group and 35 in negative group. There were no statistically significant differences in the O-C 2 angle and CROM between preoperative and last follow-up in the 53 patients ( P>0.05), and the M-P angle was significantly decreased at the last follow-up compared with that before operation ( P<0.05). Compared with negative group, O-C 2 angle and M-P angle were significantly decreased at the last follow-up ( P<0.05), and no significant change was found in CROM in positive group ( P<0.05). Compared with that before operation, the M-P angle was significantly decreased at the last follow-up in both groups, and the O-C 2 angle was significantly decreased at the last follow-up in positive group ( P<0.05). The areas under the receiver operating characteristic curves of O-C 2 angle, M-P angle and CROM in predicting difficult airway were 0.895, 0.888 and 0.519 respectively. Conclusions:The decrease in the O-C 2 angle and M-P angle after occipitocervical fusion surgery can increase the risk of difficult airway, and both can be used for airway assessment in the patients undergoing this kind of surgery.

Objective To analyze the epidemiological characteristics of human brucellosis in northern and southern areas of China,and to develop national strategies for brucellosis prevention and control.Methods Individual data on human brucellosis was collected from the National Notifiable Infectious Disease Reporting Information System to describe the situation of brucellosis in China during 2015-2016.Epidemiological features of the disease in northem and southern areas of China were analyzed.Results A total of 104 125 cases were reported in mainland China during 2015-2016,with an average incidence rate as 3.81/100 000.The overall incidence rate from the northem provinces was 7.77/100 000 in 2016,a 18.6％ decrease from 2015 (9.55/100 000),whereas the incidence rate in the southern provinces was 0.27/100 000 in 2016,with an increase of 28.6％ than 0.21/100 000 in 2015.90.0％ of the newly infected counties mainly distributed in southern China.As for the locations of reporting cases,most of them were in the same counties in the northern areas (52.3％) while most cases in the southern areas (59.6％) were imported from other counties.The median age of the cases was 48 (IQR:38-58) years,with male-to-female ratios as 2.7 ∶ 1 in the north and 2.2 ∶ 1 in the south.Majority of the cases were occupation-related,from both the northern (86.8％) and southern (62.7％) areas.Human brucellosis occurred every month throughout the year but with an obvious seasonal increase between March and July.Conclusions Different epidemiological features of human brucellosis appeared in both northern and southern areas of China.The disease was seen endemic in the northem and dispersal in the southem provinces.Appropriate strategies for brucellosis prevention and control should be developed,according to the different epidemiological characteristics in the northcm or southcm areas.

Clinical studies have validated low-level viremia is associated with a variety of adverse outcomes in patients with chronic hepatitis B during the course of receiving nucleos(t)ide analogue antiviral therapy. With the advancement of PCR technology, the high sensitivity PCR detection of HBV DNA can reach the lower limit of detection of < 5-10 IU/mL. The standard criterion for judging among patients who have achieved complete virological response is HBV DNA levels < 20 IU/ml. The use of highly sensitive PCR tests can detect very low-level viremia (HBV DNA < 20 IU/ml, but > 5-10 IU/mL) in some patients. However, there are currently fewer relevant studies, and more research data needs to be accumulated to answer this clinical question of whether long-term very low-level viremia affects the clinical outcome of patients with chronic hepatitis B.

Objective To explore the effect of sling exercise with Tuina therapy on kinesiophobia in old patients with lumbar disc herniation,and analyze the mechanism based on brain-bone axis. Methods A total of 56 old patients with chronic lumbar disc herniation and kinesiophobia were selected from the Reha-bilitation Hospital of the Second Affiliated Hospital of Shandong University of Traditional Chinese Medicine from September,2022 to December,2023;and randomly divided into control group(n=28)and experimental group(n=28).The control group accepted conventional exercise therapy,while the experimental group accepted sling exercise with Tuina therapy,for four weeks.They were assessed with simplified Chinese version of Tampa Scale of Kinesiophobia(TSK),Japanese Orthopaedic Association score(JOA)and Visual Analogue Scale for pain(VAS)before and after treatment,while the bone mineral density(BMD)was tested,the levels of osteoprote-gerin(OPG),norepinephrine(NE)and corticosteroids(Cor)in serum were measured,and the median frequency(MF)of weak-link erector spinae was detected with surface electromyography. Results Two cases dropped off in the control group,and one in the experimental group.The scores of all the assessment improved in both groups after treatment(|t|>14.168,P<0.001),as well as the serum levels of OPG,NE and Cor(|t|>2.103,P<0.05),BMD(|t|>2.726,P<0.05),and MF of erector spinae(|t|>14.736,P<0.001);all of them were better in the experimental group than in the control group(|t|>2.154,P<0.05). Conclusion Sling exercise with Tuina therapy can improve the pain and kinesiophobia of lumbar disc herniation in the old adults,which may promote the recovery of physical and mental function through regulating the levels of hor-mones and neurotransmitters related to the brain-bone axis.

Objective To evaluate the risk of bias and reporting quality in randomized controlled trials(RCTs)of the Chinese medicine injection for acute cerebral infarction in the last five years.Methods RCTs literature on Chinese medicine injection in the treatment of acute cerebral infarction was systematically searched in CNKI,Wanfang Data,VIP,China Biology Medicine Database(CBM),PubMed,Embase and Cochrane Library from April 20,2018 to April 20,2023.The risk of bias and reporting quality of included RCTs were evaluated using the Cochrane Risk of Bias Tool(ROB 1.0)and CONSORT-CHM Formulas 2017,respectively.Results A total of 4 301 articles were retrieved,and 408 RCTs were included according to inclusion and exclusion criteria.The ROB evaluation results showed that the the majority of studies were rated as having an unclear risk of bias due to the lack of reporting on allocation concealment,blind method,trial registration information,and funding sources.The evaluation results of CONSORT-CHM Formulas 2017 showed that the number of reported papers of 17 items was greater than or equal to 50%,and the number of reported papers of 25 items was less than 10%,and most of the RCTs did not show the characteristics of TCM syndrome differentiation and treatment.Conclusion The quality of Chinese medicine injection in the treatment of acute cerebral infarction RCTs is generally low.It is recommended that researchers refer to the methodology design of RCTs and international reporting standards,improve the trial design,standardize the trial report,and highlight the characteristics of TCM syndrome differentiation and treatment.
