Objective:To evaluate the effects of different subanesthetic doses of esketamine on lung injury in elderly patients undergoing robot-assisted radical prostatectomy.Methods:Ninety American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ patients, aged 65-80 yr, with body mass index of 19-27 kg/m 2, scheduled for elective robot-assisted radical prostatectomy under general anesthesia, identified as having middle and high risk using the Assess Respiratory Risk in Surgical Patients in Catalonia, were divided into 3 groups ( n=30 each) using a random number table method: low-dose esketamine group (ES1 group), extremely low-dose esketamine group (ES2 group) and control group (C group). In ES1 group, esketamine was intravenously injected as a bolus of 0.2 mg/kg during anesthesia induction followed by an infusion of 0.125 mg·kg -1·h -1 until 30 min before the end of operation. In ES2 group, esketamine was intravenously injected as a bolus of 0.1 mg/kg during anesthesia induction followed by an infusion of 0.015 mg·kg -1·h -1 until 30 min before the end of operation. The equal volume of normal saline was given instead in C group. Radial artery blood samples were collected before anesthesia induction (T 0) and at the end of operation for determination of concentrations of Clara cell secretory protein (CC-16) and soluble form of advanced glycation end products receptor (sRAGE) in serum by enzyme-linked immunosorbent assay. The parameters of respiratory mechanics such as the driving pressure, dynamic lung compliance and mechanical power were recorded at 5 min after mechanical ventilation (T 1), and at 1 and 2 h after Trendelenburg position combined with pneumoperitoneum (T 2-3), and at 5 min before the end of operation (T 4). Blood samples were collected from the radial artery at T 0, T 1, T 3 and in the postanesthesia care unit for blood gas analysis, and the alveolar-arterial partial oxygen pressure difference and oxygenation index were recorded. The adverse reactions within 24 h after operation and the occurrence of postoperative pulmonary complications within 7 days after operation were recorded. Results:Compared with C group, the serum CC-16 and sRAGE concentrations were significantly decreased at the end of operation, the oxygenation index was increased and the alveolar-arterial partial oxygen pressure difference was decreased in the postanesthesia care unit, and the incidence of postoperative nausea reactions within 24 h after operation was decreased in ES1 and ES2 groups ( P<0.05 or 0.01). Compared with ES2 group, the serum CC-16 and sRAGE concentrations were significantly decreased at the end of operation in ES1 group ( P<0.05). There were no statistically significant differences in the driving pressure, dynamic lung compliance and mechanical power at T 1-4 and the incidence of postoperative pulmonary complications within 7 days after surgery among the three groups ( P>0.05). Conclusions:Esketamine given as a subanesthetic bolus of 0.2 mg/kg during anesthesia induction followed by an infusion of 0.125 mg·kg -1·h -1 can alleviate lung injury in elderly patients undergoing robot-assisted radical prostatectomy.

Objective:To observe the effect of combining robot-assisted gait training (RAGT) with task-oriented training (TOT) on the walking ability of children with dyskinetic cerebral palsy (DCP).Methods:Sixty DCP children were randomly divided into a conventional intervention group, an RAGT group, and a combined intervention group, each of 20. All of the children received conventional rehabilitation therapy, while the RAGT and combined intervention groups were additionally provided with RAGT, and RAGT combined with TOT, respectively. Before the experiment and after 12 and 24 weeks of treatment, the subjects′ walking ability was evaluated using the 10-metre walk test (10MWT), and the D energy zone (standing position) and the E energy zone (walking, running and jumping) of the Gross Motor Function Measurement-88 (GMFM-88) instrument.Results:After 12 and 24 weeks of treatment, the average 10MWT speed and D and E energy zone scores of all three groups had improved significantly. After 24 weeks the combined group′s averages on all three measures were significantly better than those of the other two groups.Conclusion:RAGT combined with TOT and conventional rehabilitation training significantly improves the walking ability of DCP children.

【Objective】 To evaluate the clinical value of capsule endoscope in the diagnosis of unexplained abdominal pain. 【Methods】 We made a retrospective analysis of 191 patients with unexplained abdominal pain who sought medical help in our hospital and 25 normal controls. Capsule endoscopy was performed in both groups, small bowel lesions were detected, and clinical data were collected for further analysis. 【Results】 The total small bowel lesion detection rate was 52.87% (101/191) in abdominal pain (AP) patients and 20% (5/25) in the control group, respectively. The detection rate of significant findings (ulcers, erosions, polyps, diverticula, parasites, and neoplastic organisms) was only 16.23% (31/191) in AP patients. In the non-significant findings, no statistical difference in the detection rates for vascular malformation, capillary dilation, and lymphoid follicular hyperplasia were found between the two groups, while the detection rate of intestinal lymphangiectasia was significantly higher in the AP patients (23.56% vs. 4%, P<0.05, OR=7.089). 【Conclusion】 Capsule endoscopy can be an optional choice for diagnosis of unexplained abdominal pain, while the relationship between positive findings and abdominal pain should be further investigated.

To prepare a lipid nanoparticle (LNP)-based subunit vaccine of Mycobacterium tuberculosis (Mtb) antigen EsxV and study its immunological characteristics, the LNP containing EsxV and c-di-AMP (EsxV: C: L) was prepared by thin film dispersion method, and its encapsulation rate, LNP morphology, particle size, surface charge and polyphase dispersion index were measured. BALB/c mice were immunized with EsxV: C: L by nasal drops. The levels of serum and mucosal antibodies, transcription and secretion of cytokines in lung and spleen, and the proportion of T cell subsets were detected after immunization. EsxV: C: L LNPs were obtained with uniform size and they were spherical and negatively charged. Compared with EsxV: C immunization, EsxV: C: L mucosal inoculation induced increased sIgA level in respiratory tract mucosa. Levels of IL-2 secreted from spleen and ratios of memory T cells and tissue-resident T cells in mice were also elevated. In conclusion, EsxV: C: L could induce stronger mucosal immunity and memory T cell immune responses, which may provide better protection against Mtb infection.

Background: MicroRNAs (miRNAs) exert an essential contribution to obesity and type 2 diabetes mellitus (T2DM). This study aimed to investigate the differences of miRNAs in the presence and absence of T2DM in patients with obesity, as well as before and after bariatric surgery in T2DM patients with obesity. Characterization of the common changes in both was further analyzed. Methods: We enrolled 15 patients with obesity but without T2DM and 15 patients with both obesity and T2DM. Their preoperative clinical data and serum samples were collected, as well as 1 month after bariatric surgery. The serum samples were analyzed by miRNA sequencing, and the miRNAs profiles and target genes characteristics were compared. Results: Patients with T2DM had 16 up-regulated and 32 down-regulated miRNAs compared to patients without T2DM. Improvement in metabolic metrics after bariatric surgery of T2DM patients with obesity was correlated with changes in miRNAs, as evidenced by the upregulation of 20 miRNAs and the downregulation of 30 miRNAs. Analysis of the two miRNAs profiles identified seven intersecting miRNAs that showed opposite changes. The target genes of these seven miRNAs were substantially enriched in terms or pathways associated with T2DM. Conclusion We determined the expression profiles of miRNAs in the obese population, with and without diabetes, before and after bariatric surgery. The miRNAs that intersected in the two comparisons were discovered. Both the miRNAs discovered and their target genes were closely associated with T2DM, demonstrating that they might be potential targets for the regulation of T2DM.

ObjectiveTo explore the effect of Anmeidan on the sleep quality and serum levels of brain-derived neurotrophic factor （BDNF）， glial fibrillary acidic protein （GFAP）， and irisin in the patients with chronic insomnia. MethodA multicenter， randomized， double-blind， placebo-controlled clinical study was carried out， including 480 patients with chronic insomnia （deficiency syndrome） in Wuhan （Hubei）， Guangzhou （Guangdong）， and Lanzhou （Gansu）. They were randomized into an observation group and a control group at a ratio of 1∶1. The observation group was orally administered with Anmeidan granules at a dose of 11 g， 3 times per day， and the control group with Anmeidan simulant at a dose of 11 g， 3 times per day， Both groups of patients received sleep education after enrollment. After 4 weeks of medication， the Athens insomnia scale （AIS） scores， Spiegel scale scores， and serum levels of BDNF， GFAP， and irisin were compared between the two groups as well as between before and after treatment. ResultA total of 480 adult patients with chronic insomnia were enrolled in this study， with 64 patients falled off. Finally， the 415 patients were included in the analysis， including 213 patients in the observation group and 202 patients in the control group. There was no difference in age or sex between the two groups of patients. Compared with before treatment， the treatment in both groups decreased the AIS and Spiegel scores （P<0.01）. After treatment， the observation group had lower AIS and Spiegel scores than the control group （P<0.01）. The treatment in the observation group slightly lowered the level of BDNF， elevated the level of irisin （P<0.05）， and lowered the level of GFAP （P<0.05） in the serum. After treatment， the observation group showed higher level of irisin （P<0.05） and lower levels of BDNF and GFAP in the serum than the control group. ConclusionAnmeidan may improve the sleep quality of patients with chronic insomnia by elevating the irisin level and lowering the GFAP level in the serum.
