Objective:To compare the short-term efficacy between our self-designed intelligent robot-assisted minimally invasive reduction system and conventional freehand reduction assisted by fluoroscopy in the treatment of unstable pelvic fractures by robot or fluoroscopy-assisted internal fixation with percutaneous screws.Methods:A prospective randomized controlled trial was conducted to include eligible 35 patients with unstable pelvic fracture who were admitted to Department of Orthopaedic Trauma, Beijing Jishuitan Hospital from December 2021 to October 2022. They were randomized into 2 groups. The observation group[17 cases, 10 males and 7 females with an age of (44.0±17.4) years] was treated with robot-assisted minimally invasive reduction, followed by robot-assisted or fluoroscopic internal fixation with percutaneous screws; the control group[18 cases, 12 males and 6 females with an age of (38.8±15.0) years] was treated with freehand reduction assisted by fluoroscopy, followed by robot-assisted or fluoroscopic internal fixation with percutaneous screws. The 2 groups were compared in terms of operation time, intraoperative bleeding, successful reduction, reduction quality, incidence of surgical complications and postoperative functional scores.Results:The 2 groups were comparable because there were no significant differences in the preoperative general data between them ( P>0.05). The intraoperative fluoroscopy frequency[(32.4±17.5) times] and fluoroscopy time [(19.8±10.4) s] in the observation group were significantly lower or shorter than those in the control group [(60.8±26.6) times and (38.2±16.1) s], and the rate of successful reduction in the observation group was 100.0% (17/17), significantly higher than that in the control group[72.2% (13/18)] ( P<0.05). There was no significant difference between the 2 groups in intraoperative bleeding, operation time, reduction error, excellent and good rate of reduction after operation by Matta scoring, or Majeed functional score at 12 weeks after operation ( P>0.05). Conclusion:In the treatment of unstable pelvic fractures, since our self-designed intelligent robot-assisted minimally invasive reduction system can plan autonomously the reduction paths and accomplish minimally invasive reduction of the fracture with 3D images real-time monitoring, it is advantageous over conventional reduction methods in a higher success rate and less radiation exposure.

Objective: To observe the effects of acupuncture at Yuan-Primordial and Luo-Connecting points by host-guest combination plus Tuina (Chinese therapeutic massage) on the third lumbar transverse process syndrome. Methods: A total of 88 patients with the third lumbar transverse process syndrome were selected and divided into an observation group and a control group according to the random number table method, with 44 cases in each group. The control group was treated with Tuina, and the observation group was treated with additional acupuncture at Yuan-Primordial and Luo-Connecting points by host-guest combination. The clinical efficacy of the two groups was compared after treatment. The changes in the scores of physical signs, Roland-Morris disability questionnaire (RMDQ), Oswestry disability index (ODI), Quebec back pain disability scale (QBPDS), and pain factors [including serum prostaglandin (PG) E2, neuropeptide Y (NPY), and matrix metalloproteinase-3 (MMP-3)] were observed. Results: After treatment, the total effective rate in the observation group was 93.2％, higher than 75.0％ in the control group; the difference between the two groups was statistically significant (P<0.05). Compared with those before treatment, the scores of physical signs and each low back pain scale, and the levels of serum pain factors in the two groups were decreased (P<0.05), and those in the observation group were lower than those in the control group (P<0.05). Conclusion: Acupuncture at Yuan-Primordial and Luo-Connecting points by host-guest combination plus Tuina is effective in the treatment of the third lumbar transverse process syndrome; it can improve the patient's physical signs, relieve low back pain, and reduce the levels of serum pain factors.

For the past few years, viral diseases such as Coronavirus Disease 2019, Influenza, and Ebola hemorrhagic fever have become more severe and more frequent. For people’s health and the stable operation of the national economy, it is of increasing importance to research the pathogenesis of virus and host immune regulation mechanism, analyze the regulation of gene expression between virus and host, and surveil pathogenic viruses and prevent virus diseases. Transcriptome sequencing is a kind of technology at the RNA level that focuses on the expression characteristics of genes in a specific space-time state, and it is an indispensable tool for analyzing differential gene expression and researching differential splicing of mRNA. With the progress of molecular biology experimental technology and the maturity of bioinformatics analysis platforms, transcriptomics is developing towards the low-cost and low technical threshold, which is gradually transitioning from the research field to the clinical laboratory and changing the traditional cognition of clinical staff in viruses and viral diseases. It has been increasingly used in the research of viral transcription mechanisms, immune interaction between virus and host, tracking disease progression, and antiviral drug development. In order to provide a methodological reference for the research of virus mechanism and prevention and control of virus disease, here, we mainly review meta-transcriptome from three aspects: technical process, common software and application scenarios of virus and virus diseases, and briefly mention the method and applications of other transcriptomes, including a population of cells RNA sequencing (Bulk RNA-seq), Single-cell RNA sequencing (ScRNA-seq), Single-nuclear RNA sequencing (SnRNA-seq), and Spatial Transcriptome (ST).

A case of severe complications is presented that replaced the double J tubeless misguided by zebra guidewire into ileum in a patient with ureteral dermostomy, causing a ureteral ileum fistula.The result suggests improper operation of zebra guidewire could have a risk of ureteral perforation when the ureter is distorted, narrow or with inflammatory lesions.Standardized diagnosis and treatment and correct selection of guidewire can reduce the risk of ureteral perforation.

Objective: To explore the influence of psychological intervention before percutaneous coronary intervention (PCI) on mental stress, coping style and related factors of depression in patients with acute coronary syndrome (ACS). Methods: 281 patients with ACS who were treated in our hospital from March 2016 to August 2018 were selected as the study subjects. According to whether psychological intervention was given to ACS patients before PCI, they were divided into intervention group (n = 135) and control group (n = 146). SCL-90 was used to assess mental stress and MCMQ was used to assess coping styles. The changes of mental stress and coping style before and after operation were compared between the two groups. To investigate the incidence of depression in ACS patients after PCI and analyze the related factors affecting their depression. Results: After PCI, the scores of somatization, obsessive-compulsive disorder, interpersonal sensitivity, depression, anxiety, hostility, fear, paranoia, psychosis and bedtime status were decreased in the SCL-90 scores of the intervention group and the control group (P<0.05). The reduction in the intervention group was more obvious, and the difference was statistically significant (P<0.05). After PCI, there was no significant difference in avoidance and yield between the two groups (P>0.05), and there was no significant difference between the two groups before PCI (P>0.05). After PCI, the face score of intervention group was higher than that of control group (P<0.05), and compared with pre-PCI, the difference was also statistically significant (P<0.05). Of the 281 patients with ACS, 84 (29.89%) had depression after PCI. In the intervention group, 26 patients (19.26%) suffered from depression, and 58 patients (39.73%) in the control group suffered from depression. The prevalence of depression in the two groups was statistically significant (P<0.05). Univariate and multivariate logistic analysis showed that the degree of coronary artery disease, education and psychological intervention before PCI were closely related to ACS patients with post-PCI complicated with depression. Conclusion Psychological intervention can improve the stress of ACS patients and reduce the negative response. At the same time, it can reduce the risk of depression after PCI.

Objective: To screen the risk factors of depression in patients with coronary heart disease(CHD) after percutaneous coronary intervention(PCI), and to construct a predictive model of depression in patients with CHD after PCI and to analyze its diagnostic efficacy. Methods: A total of 3 048 patients with CHD who were treated in our hospital from April 2015 to January 2019 were selected as the study subjects. 967 patients with depression after PCI were selected as depression group. 967 patients without depression after PCI were randomly selected as CHD group according to 1:1 ratio. Univariate and multivariate logistic regression analysis were used to analyze the risk factors of depression in patients with CHD after PCI, and to construct a predictive model of depression in patients with CHD after PCI. The ROC curve was used to analyze the diagnostic efficacy of a predictive model of depression in patients with CHD after PCI. Results: Of 3 048 patients with CHD, 967 (31.73%) suffered from depression after PCI. There were significant differences in age, sex, type D personality, smoking history, NYHA classification, number of stents implanted, solitary living, emergency PCI, Gensini score and education level between the two groups (P<0.05). Logistic regression analysis showed that age, type D personality, NYHA grade, solitude and education were risk factors for depression after PCI. The area under ROC curve of depression model after PCI in CHD patients was 0.961 (95% CI: 0.910-0.987), the sensitivity and specificity were 96.00% and 90.82% respectively. Conclusion The model constructed in this study can predict the risk of depression in patients with CHD after PCI and is more effective.

Objective To discuss the clinical effects of different energy densities of enteral nutrition (EN) preparations on mechanical ventilation (MV) patients with acute severe traumatic brain injury (sTBI). Methods Sixty MV patients with acute sTBI admitted to the Department of Critical Care Medicine of Hangzhou Xiaoshan District First People's Hospital from July 2015 to December 2017 were divided into two groups according to different energy densities of nutritional preparations. Thirty patients of the control group were given nasal feeding with standard energy density EN (energy density 3.35 - 4.19 kJ/mL) and 30 patients of the observation group were given nasal feeding with relatively higher energy density (energy density 5.44 - 6.28 kJ/mL). The indexes of nutritional status between the two groups before and after treatment were compared: including prealbumin (PA), albumin (Alb), globulin (Glo), hemoglobin (Hb), 5-day and 1-week heat calorie compliance rates of reaching target calories, MV time and incidence of complications. Results There were no statistically significant differences in nutritional indicators before treatment between the two groups (all P > 0.05). The compliance rates of reaching target calories of the observation group on the 5 and 7 days after treatment were significantly higher than those in the control group [5 days: 66.67% (20/30) vs. 50.00% (15/30), 1 week: 81.33% (25/30) vs. 70.00% (21/30), both P < 0.05], and the MV time was significantly lower than that in the control group (hours: 92.48±12.04 vs. 128.88±16.29, P < 0.05); the levels of PA, Alb, Hb, Glo were significantly higher in the observation group than those in control group on the 21st day after treatment [PA (g/L): 0.28±0.11 vs. 0.15±0.04, Alb (g/L): 36.52±5.79 vs. 29.63±2.74, Hb (g/L): 92.40±9.50 vs. 81.10±8.60, Glo (g/L): 24.42±1.73 vs. 18.19±3.59, all P < 0.05]. Complications: the total incidence of abdominal distension, diarrhea and constipation of the observation group was 36.6% (11/30), while that of the control group was 66.7% (20/30), the difference between the two groups being statistically significant (P < 0.05). Conclusion High energy density enteral nutrition can improve the nutritional status of the organisms of MV patients with acute sTBI, reduce the time of MV and the incidence of complications, thus it is worthy to be widely applied clinically.
