Objective:To evaluate the reliability and validity of the Chinese version of HEMO-FISS-QoL(HF-QoL) questionnaire (HF-QoL-C) in the Chinese population with hemorrhoids.Methods:From November 2021 to November 2022, a self-constructed general information questionnaire, HF-QoL-C, and the 36-item short form health survey (SF-36), Goligher classification, and Giordano severity of hemorrhoid symptom questionnaire (GSQ) were used to conduct a questionnaire survey on 760 hemorrhoid patients in the anorectal department of six hospitals. The data was analyzed for reliability and validity using SPSS 21.0 and AMOS 26.0 software.Results:The Cronbach's α coefficient of HF-QoL-C and its dimension ranged from 0.831 to 0.960, and the split coefficient was 0.832-0.915. Four common factors were extracted through principal component exploratory factor analysis. Confirmatory factor analysis indicated acceptable structural validity( χ2/ df=8.152, RSMEA=0.097, CFI=0.881, IFI=0.881, NFI=0.867). HF-QoL-C was correlated with SF36 and GSQ( r=-0.694, 0.501, both P<0.01). There were differences in the total score and dimensional scores of HF-QoL-C between surgical and drug treated patients, different grades of Goligher classification for hemorrhoidal disease, and different ranges of hemorrhoid prolapse (all P<0.001). No ceiling effect was found in the total score and the scores of each dimension(0.3%-2.0%). There was a floor effect in both psychological function and sexual activity dimensions (16.7%, 35.1%). Conclusion:HF-QoL-C has good reliability and validity, which can be used to measure the quality of life of Chinese hemorrhoid patients.

The clinical data of patients with chlamydia psitsiti pneumonia confirmed by metagenomic next-generation sequencing (mNGS) who were admitted to the Huizhou Municipal Central Hospital from January 2020 to November 2021 were retrospectively analyzed. Among 21 patients, the serum creatine kinase (CK) was elevated in 10 cases, and 5 cases was complicated with rhabdomyolysis (RM). The symptoms of patients with Chlamydia psittaci pneumonia-induced RM were severe, including high fever, dyspnoea, headache and myalgia; 2 case were complicated by acute kidney injury (AKI) and neurological symptoms. Laboratory testing showed a marked increase in CK, myoglobin (Mb), high sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6) and D-dimer levels in all 5 patients. The chest CT revealed large areas of pulmonary consolidation, ground-glass opacity in 1 case and a small amount of pleural effusion in 2 cases. One patient died from multiple organ failure, and the other 4 patients were discharged with considerable improvement. Patients with psittacosis pneumonia are prone to developing rhabdomyolysis, early detection and early treatment can effectively improve the prognosis of patients.

Objective:To investigate the characteristics of distribution and drug resistance of urinary bacteria in the mid-stream urine of patients with infectious stones.Methods:The retrospective study analyzed the clinical data of 254 patients with infectious stones in the First Affiliated Hospital of Guangzhou Medical University from September 2016 to September 2018. All patients were treated with PCNL. Overall, there were 101 male and 153 female patients, with the mean age of(51.5±12.3) years, and the mean stone burden of 1443.5(660.8, 2837.5) mm2. There were 58 (22.8%) patients with hypertension, 17(6.7%) patients with diabetes and 195(76.8%)with hydronephrosis. The mid-stream urine samples were obtained for bacterial culture and susceptibility test, and the results of urine culture and antimicrobial susceptibility were recorded and analyzed.Results:Of 254 patients involved in this study, 89(35.0%) were positive and 165 (65.0%) were negative for urinary bacterial culture of the mid-stream. The proportion of patients with positive urine bacterial culture of the mid-stream who had positive urine leucocytes, positive urine nitrite and postoperative pyrexia were 86.5%(77/89), 64.0%(57/89), 25.8%(23/89), respectively, which was higher than that of patients with negative urine bacterial culture of the mid-stream [50.3%(83/165), 14.5%(24/165), 14.5%(24/165), P<0.05]. Four teen kinds of bacteria were detected from the mid-stream urine, and the three bacteria with the highest detection rate in turn were Escherichia coli of 38.2%(34/89), Proteus mirabilis of 15.7%(14/89), and Pseudomonas aeruginosa of 11.2%(10/89). The results of this study showed that three common bacteria had high resistance to drug including Cefazolin, Cefuroxime, Cefuroxime ester, Ampicillin and Co-trimoxazole (all resistance rate>40%). The resistance rates of Escherichia coli and Pseudomonas aeruginosa to Ciprofloxacin and Levofloxacin were higher than or equal to 40%. The resistance rates of Escherichia coli and Proteus mirabilis to meropenem, imipenem, ertapenem, piperacillin/tazobactam and amikacin were all lower than 10%. In addition, the resistance rates of Escherichia coli to nitrofurantoin and tigecycline and Proteus mirabilis to tobramycin, aztreonam and cefoxitin were all less than 10%. The resistance rates of Pseudomonas aeruginosa to ceftazidime, cefepime, gentamicin and aztreonam were less than 10%. Conclusions:The highest detection rate of urinary bacteria in culture of the mid-stream with infectious stones are Escherichia coli, Proteus mirabilis and Pseudomonas aeruginosa, all of which showed high resistance to Ampicillin, Cotrimoxazole, and some cephalosporins. Escherichia coli and Pseudomonas aeruginosa showe high resistance to Ciprofloxacin and Levofloxacin, and all of the three bacteria have low resistance rates to some β-Lactamase inhibitor complex and carbapenems, suggesting a reference for clinical empirical medical treatment.

Toll-like receptor 3 (TLR3) is a member of the TLR family, mediating the transcriptional induction of type I interferons (IFNs), proinflammatory cytokines, and chemokines, thereby collectively establishing an antiviral host response. Studies have shown that unlike other TLR family members, TLR3 is the only RNA sensor that is utterly dependent on the Toll-interleukin-1 receptor (TIR)‍-domain-containing adaptor-inducing IFN-‍β (TRIF). However, the details of how the TLR3-TRIF signaling pathway works in an antiviral response and how it is regulated are unclear. In this review, we focus on recent advances in understanding the antiviral mechanism of the TRIF pathway and describe the essential characteristics of TLR3 and its antiviral effects. Advancing our understanding of TLR3 may contribute to disease diagnosis and could foster the development of novel treatments for viral diseases.

Objective:To deeply understand the real experience of family members of patients in the neurosurgery intensive care unit during the period of accompanying them, and to provide reference for managers to formulate nursing countermeasures to improve the coping ability of family members.Methods:Descriptive phenomenological research method in qualitative research was adopted to conduct in-depth interviews with family members of 12 patients admitted to a neurosurgery intensive care unit in Shanghai, manage the interview data with Nvivo11 software, and use Colaizzi's seven-step analysis method to summarize and analyze the topic.Results:There were four themes: adhere to and do not give up, adhere to was due to the trust and affirmation of the medical care, do not give up was because it was difficult to give up blood kinship, adhere to the hope of life because of patients; timing change of emotional experience, first aid period: helpless to rescue and expecting the condition to stabilize, complication peak: understanding the characteristics of the disease and paying attention to the treatment progress, stable period: uncertain prognosis and desire for emotional companionship.The powerlessness of the future; learn to self psychological adjustment.Conclusions:The family members of patients with severe neurological diseases have both negative experience and positive feelings, and the accompanying experience and needs at different stages of the disease are changing dynamically. According to the cognition and needs of the family members, exploring and developing palliative medicine, tapping the potential of the family members from a positive perspective and improving coping ability are one of the ways to maintain the stable mental health of the family members.

Objective:To analyze the clinical characteristics of Chlamydia psittaci pneumonia and to investigate the correlation between serum inflammatory biomarkers and severity of the disease. Methods:Sixteen patients with Chlamydia psittaci pneumonia admitted to the Huizhou Municipal Central Hospital from January 2020 to July 2021 were selected as the study subjects, including 10 severe cases and 6 mild cases. Clinical data were collected and analyzed, such as baseline characteristics, clinical symptoms, laboratory inspection and chest imaging manifestations. Results:① Thirteen Chlamydia psittaci pneumonia were associated with a definite bird or poultry contact history. Common symptoms included high fever, chill, cough, fatigue, and anorexia (16 cases), dyspnoea (12 cases), and other systemic symptoms. ② Laboratory test results showed normal white blood cell count (WBC, 10 cases), decreased lymphocyte count (LYM, 13 cases), increased high sensitive C-reactive protein (hs-CRP, 16 cases), D-dimer (15 cases), lactate dehydrogenase (LDH, 13 cases), aspartate aminotransferase (AST, 16 cases) and alanine aminotransferase (ALT, 12 cases) levels, however, the albumin (Alb, 15 cases) lever was decreased. The numbers of CD3 + T cells and CD4 + T cells decreased in 10 patients. ③ The levels of D-dimer, interleukins (IL-2, IL-6, IL-10) in severe Chlamydia psittaci pneumonia were significantly higher than those in mild Chlamydia psittaci pneumonia [D-dimer (μg/L): 10 257±4 203 vs. 1 085±642, IL-2 (ng/L): 1.1 (0.8, 1.7) vs. 0.3 (0.1, 0.7), IL-6 (ng/L): 315 (182, 505) vs. 75 (18, 131), IL-10 (ng/L): 7.0±4.1 vs. 2.3±0.7], but the LYM was lower (×10 9/L: 0.4±0.1 vs. 1.1±0.4), with significant differences (all P < 0.05). ④ Chest imaging manifestations were exudative lesions and large consolidation of lungs. Large consolidation of both lungs can occur in some critically ill patients. Conclusions:Chlamydia psittaci pneumonia is mainly associated with a bird or poultry contact history. The clinical manifestations usually present high fever, dyspnea, normal or slightly increased leucocytes, and lung consolidation. The levels of LYM, D-dimer, IL-2, IL-6 and IL-10 in serum are expected to predict the severity of the Chlamydia psittaci pneumonia.

Bluetongue virus (BTV) causes Bluetongue (BT) of ruminants vectored by culicoides midges. It is also a classic model for studying the release mechanism of non-enveloped virus. This review begins with the infection and assembly of BTV, then summarizes the advances of different ways of releasing BTV. This includes BTV-induced autophagy and the release as extracellular vesicles via multivesicular bodies, BTV-induced apoptosis and the lytic release, as well as different pathways of release through budding via plasma membrane. The regulatory mechanisms of NS3 which is a key non-structural protein during the release of BTV are also discussed, providing a basis for further understanding the molecular mechanisms underpinning the infection, proliferation and release of BTV.

Objective:To analyze the clinical features and follow-up results of children with acute exogenous lipoid pneumonia (ELP), and to investigate the diagnosis strategy, treatment and risk factors of ELP.Methods:The clinical features, imaging manifestations, results of bronchoalveolar lavage fluid (BALF), treatment methods and prognosis of 41 ELP inpatients in Guangzhou Women and Children′s Medical Center, Guangzhou Medical University from May 2013 to May 2018, were summarized and analyzed, and the related literature was reviewed.Results:(1) Among 41 patients, 29 cases were male and 12 cases were female.The age of onset ranged from 4 to 53 months.Most of them (35/41 cases, 85.4%) were less than 3 years old, and the majority were aged 1 to 2 years (23/41 cases, 56.1%). (2) The grease taken by children by accident included perfume oil (11 cases), white electric oil (7 cases), electric mosquito oil (5 cases), lubricating oil (5 cases), paraffin oil (4 cases), gasoline/diesel oil (3 cases), kerosene (2 cases), cod-liver oil (2 cases), sewing machine oil (1 case), and unclear oil (1 case). (3) The main clinical manifestations were cough (26/41 cases, 63.4%), shortness of breath (23/41 cases, 56.1%), fever (17/41 cases, 41.5%), cyanosis with hypoxemia (15/41 cases, 36.6%), wheezing (9/41 cases, 22.1%), respiratory distress (9/41 cases, 22.1%), pulmonary hemorrhage (6/41 cases, 14.7%), feeding difficulties and transient vomiting (4/41 cases, 9.8%). Some cases showed no symptoms (3/41 cases, 7.3%). (4) Chest X-ray mainly showed bilateral pulmonary exudative changes or pulmonary consolidation.The most common sign of high-resolution computerized tomography (HRCT) was local or extensive exudation, often accompanied by pulmonary consolidation (18/41 cases, 43.9%). The most common affected sites were bilateral lower lobes (8/41 cases, 19.5%), followed by right lower lobes (3/41 cases, 7.3%), right middle lobes (2/41 cases, 4.8%) and left lower lobes (2/41 cases, 4.8%). Other signs included alveolar changes, hyperventilation, ground glass changes, and nodule formation.(5) Seven children needed mechanical ventilation due to respiratory failure, and all patients underwent bronchoalveolar lavage (BAL). All patients recovered without death, with (11.67±4.90) days of hospitalization, and the hospitalization time of ELP patients with adenovirus infection was (19.25±5.93) days.Nine of them were lost to follow-up (8 cases were mild and 1 case was severe). The symptoms of the remaining children disappeared within 1 week to 1 month.The lung images of 21 cases returned to normal within 1 month after discharge, 7 cases returned to normal within 3 months after discharge, and 4 cases returned to normal after 6 months.Conclusion:The clinical manifestations and lung imaging of children with acute ELP have no specificity.Pulmonary imaging of severe patients shows multiple lobes involved, and consolidation and vacuolar changes may occur.Most patients have a favorable prognosis.Co-infection, especially adenovirus infection, may be a risk factor for acute ELP in children.BAL can play a role in both diagnosis and treatment, and its combination with local/systemic glucocorticoid therapy is effective for severe acute ELP.

Objective:To further understand the real experience of the nurse in the rotation of NICU in neurosurgery.Methods:Qualitative research method was used to analyze the reflective diary of 26 nurses and the semi-structured interview data of 8 nurses.Results:Three primary themes and 11 secondary themes were extracted from the real experience of rotation of nurses in the neurointensive care unit: department integration and mental process, role competency and influencing factors, career expectations and coping strategies.Conclusions:At present, the integration process of the nurses in the neurointensive care unit is slow. Influenced by many factors, it is difficult to change their roles. It is the direction that nursing managers should pay attention to establish a diversified discipline training system and create a better organizational commitment

Objective: To analyze effect of Treadmill Training on neuropsychiatric symptoms and quality of life in elderly patients with Alzheimer′s disease. Methods: From May 2018 to November 2018, the experimental design was adopted. The patients with 55-75 years old AD, the First Affiliated Hospital of Quanzhou Fujian Medical University were randomly divided into groups. Group (treadmill training, 68 patients), control group (no intervention, 68 patients). The two groups were evaluated before the training and 20 weeks after training, using the Neuropsychology Scale (NPI-Q) and the Alzheimer's disease Quality of Life Questionnaire (QOL-AD), and the t-test, two-factor repeated measures analysis of variance, etc. Statistical methods for data analysis. Results: There were no significant differences in neuropsychiatric scores and QOL scores between the two groups before training (P>0.05). After training through a 20-week treadmill, the total score of neuropsychiatric symptoms in patients with Alzheimer's disease in the experimental group (t=-1.317, P=0.204 before training; t=-10.01, P=0.046 after 20 weeks of training), affective symptoms (Before training, t=-1.684, P=0.092; t=-11.26, P=0.043 after 20 weeks of training, psychiatric symptoms (t=1.168 before training, P=0.235; t=-9.94 after training for 20 weeks, P=0.034)), behavioral symptoms (t=1.952 before training, P=0.129; t=-3.61, P=0.028 after 20 weeks of training), and QOL total score (t=1.452, P=0.140 before training; t=22.27 after training, P=0.040) were statistically different; and the improvement of neuropsychiatric symptoms in the experimental group was significantly different from that in the control group (F=23.10, P=0.000), while the QOL of the experimental group was also significantly different from the control group (t=- 8.88, P=0.000). Conclusion Non-pharmacological treatment with treadmill training can improve neuropsychiatric symptoms and improve quality of life in elderly AD patients.
