Objective:To explore the efficacy of long intramedullary nails versus short intramedullary nails in the treatment of AO/OTA 31-A3 intertrochanteric fractures.Methods:A retrospective analysis was conducted on 60 patients with AO/OTA 31-A3 intertrochanteric femur fractures treated between March 2019 and August 2022. The patients were randomly divided into two groups (the long nail group and the short nail group). Thirty-four patients were treated with long intramedullary nails, including 16 males and 18 females, aged 68.41±17.84 years old (range 31-96 years). Twenty-six patients were treated with short intramedullary nails, including 13 males and 13 females, aged 72.23±13.97 years old (range 31-90 years). The causes of injury, fracture classification (AO/OTA classification), intraoperative blood loss, operation time, fracture healing time, imaging indexes (fracture reduction quality, postoperative neck trunk angle, and medial support), Harris score of the hip joint at the last follow-up, one-year mortality rates and complications were compared between the two groups.Results:The follow-up time was 24.26±6.67 months in the long nail group and 24.31±5.60 months in the short nail group, and the general information of the two groups were comparable. Between the long nail and short nail group, the intraoperative blood loss was 281.47±235.28 ml vs. 121.92±84.14 ml and the operation time was 110.44±24.63 min vs. 81.15±28.54 min with significant differences ( P<0.05). While the length of hospital stay was 12.35±4.81 d vs. 10.89±4.30 d, the good rate of fracture reduction was 55.9% vs. 61.53%, the fracture healing time was 120.44±16.43 d vs. 128.07±18.33 d, the presence rate of medial support was 67.6% vs. 79.4%, and the excellent rate of Harris score was 65.4% vs. 65.4% with no significant difference between the two groups ( P>0.05). One-year mortality rates was 5.3% vs. 7.1% and complications was 11.7% vs. 15.4% with no significant difference between the two groups ( P>0.05). Conclusion:Both long intramedullary nails and short intramedullary nails are effective in the treatment of AO/OTA 31-A3 intertrochanteric femur fractures. However, surgical time and intraoperative blood loss was less in the short nail group.

Electroacupuncture at Sensitized Acupoints Relieves Somatic Referred Pain in Colitis Rats by Inhibiting Sympathetic-Sensory Coupling to Interfere with 5-HT Signaling Pathway / 中国结合医学杂志

OBJECTIVE@#To investigate whether electroacupuncture (EA) at sensitized acupoints could reduce sympathetic-sensory coupling (SSC) and neurogenic inflammatory response by interfering with 5-hydroxytryptamine (5-HT)ergic neural pathways to relieve colitis and somatic referred pain, and explore the underlying mechanisms.@*METHODS@#Rats were treated with 5% dextran sodium sulfate (DSS) solution for 7 days to establish a colitis model. Twelve rats were randomly divided into the control and model groups according to a random number table (n=6). According to the "Research on Rat Acupoint Atlas", sensitized acupoints and non-sensitized acupoints were determined. Rats were randomly divided into the control, model, Zusanli-EA (ST 36), Dachangshu-EA (BL 25), and Xinshu (BL 15) groups (n=6), as well as the control, model, EA, and EA + GR113808 (a 5-HT inhibitor) groups (n=6). The rats in the control group received no treatment. Acupuncture was administered on 2 days after modeling using the stimulation pavameters: 1 mA, 2 Hz, for 30 min, with sparse and dense waves, for 14 consecutive days. GR113808 was injected into the tail vein at 5 mg/kg before EA for 10 min for 7 consecutive days. Mechanical sensitivity was assessed with von Frey filaments. Body weight and disease activity index (DAI) scores of rats were determined. Hematoxylin and eosin staining was performed to observe colon histopathology. SSC was analyzed by immunofluorescence staining. Immunohistochemical staining was performed to detect 5-HT and substance P (SP) expressions. The calcitonin gene-related peptide (CGRP) in skin tissue and tyrosine hydroxylase (TH) protein levels in DRG were detected by Western blot. The levels of hyaluronic acid (HA), bradykinin (BK), prostaglandin I2 (PGI2) in skin tissue, 5-HT, tryptophan hydroxylase 1 (TPH1), serotonin transporters (SERT), 5-HT 3 receptor (5-HT3R), and 5-HT 4 receptor (5-HT4R) in colon tissue were measured by enzyme-linked immunosorbent assay (ELISA).@*RESULTS@#BL 25 and ST 36 acupoints were determined as sensitized acupoints, and BL 15 acupoint was used as a non-sensitized acupoint. EA at sensitized acupoints improved the DAI score, increased mechanical withdrawal thresholds, and alleviated colonic pathological damage of rats. EA at sensitized acupoints reduced SSC structures and decreased TH and CGRP expression levels (P<0.05). Furthermore, EA at sensitized acupoints reduced BK, PGI2, 5-HT, 5-HT3R and TPH1 levels, and increased HA, 5-HT4R and SERT levels in colitis rats (P<0.05). GR113808 treatment diminished the protective effect of EA at sensitized acupoints in colitis rats (P<0.05).@*CONCLUSION@#EA at sensitized acupoints alleviated DSS-induced somatic referred pain in colitis rats by interfering with 5-HTergic neural pathway, and reducing SSC inflammatory response.

Host metabolism dysregulation and cell tropism identification in human airway and alveolar organoids upon SARS-CoV-2 infection

The coronavirus disease 2019 (COVID-19) pandemic is caused by infection with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which is spread primary via respiratory droplets and infects the lungs. Currently widely used cell lines and animals are unable to accurately mimic human physiological conditions because of the abnormal status of cell lines (transformed or cancer cells) and species differences between animals and humans. Organoids are stem cell-derived self-organized three-dimensional culture in vitro and model the physiological conditions of natural organs. Here we showed that SARS-CoV-2 infected and extensively replicated in human embryonic stem cells (hESCs)-derived lung organoids, including airway and alveolar organoids which covered the complete infection and spread route for SARS-CoV-2 within lungs. The infected cells were ciliated, club, and alveolar type 2 (AT2) cells, which were sequentially located from the proximal to the distal airway and terminal alveoli, respectively. Additionally, RNA-seq revealed early cell response to virus infection including an unexpected downregulation of the metabolic processes, especially lipid metabolism, in addition to the well-known upregulation of immune response. Further, Remdesivir and a human neutralizing antibody potently inhibited SARS-CoV-2 replication in lung organoids. Therefore, human lung organoids can serve as a pathophysiological model to investigate the underlying mechanism of SARS-CoV-2 infection and to discover and test therapeutic drugs for COVID-19.

Psychological factors are closely associated with the Bell's palsy: A case-control study / 华中科技大学学报（医学）（英德文版）

To observe the differences in psychological status between Bell's palsy (BP) patients and healthy subjects, and to examine the relationship between psychological factors and the severity of BP, we conducted a case-control, multi-center clinical investigation. A total of 695 subjects were assigned to the case group (n=355) and the control group (n=340). House-Brackmann grading system and Facial Disability Index (FDI) were adopted to assess the BP patients; Kessler Psychological Distress Scale (K10) and 16 Personality Factor (16PF) scale were employed to evaluate the psychological distress and personality profiles of all subjects. Two independent samples t test was used to compare the differences between cases and controls, and to compare the differences among different BP patients. Pearson correlation analysis was used to examine the relationship between psychological factors and severity of facial paralysis. The results showed that psychological distress (K10) in case group (27.09±5.80) was significantly higher than that in control group (13.43±3.02) (t=-37.219, P=0.000). The scores of personality factor Warmth (A), Openness to Change (Q1), Self-Reliance (Q2) were lower in cases than in the controls (P<0.01, P<0.05, P<0.05, respectively), whereas the scores of Sensitivity (I), Vigilance (L), Apprehension (O), and Tension (Q4) were significantly higher in cases than in the controls (P<0.05, P<0.01, P<0.01, P<0.01, respectively). In addition, the psychological distress was significantly higher in female patients, severe (HB score IV-VI) patients, and subacute (onset time 72-168 h) patients compared with that in male patients, mild (HB score I-III)patients, and acute (onset time[Symbol: see text]72 h) patients (P<0.05). The scores of personality factor in female patients, severe patients, and subacute patients were also significantly different from male patients, mild patients, and acute patients (P<0.05). The result of Pearson correlation analysis showed that psychological factors (K10, personality A, F, L, N, O, Q4) were closely related to HB scores. We are led to conclude that the psychological status between BP patients and healthy people are different; psychological distress and personality factors are closely associated with severity of facial paralysis.

No significantly difference in the genotype frequencies or allele frequencies of Gly82Ser polymorphism were found between the diabetic patients and non-diabetic subjects (P>0.05).</p><p><b>CONCLUSION</b>Gly82Ser polymorphism of RAGE gene does not demonstrate any association with type 2 diabetes in Chinese patients, but high genotype and allele frequencies of Gly82Ser polymorphism occur in Chinese population and type 2 diabetic Chinese patients.</p>

A hospital information system integration solution based on an integration platform / 中国医疗器械杂志

In view of the limitation of the traditional integration solutions in the hospital information construction, this paper proposes an integration solution based on a uniform application integration platform, and analyzes the system integration architecture and the integration frame. Using this frame, we can realize the integration of the hetero structural sub-systems within the hospital.
