ABSTRACT

OBJECTIVE@#To compare the clinical efficacy of titanium cable biomimetic reconstruction of coracoclavicular ligament and clavicular hook plate in the treatment of acromioclavicular joint dislocation.@*METHODS@#The clinical data of 39 patients with severe acute acromioclavicular joint dislocation from January 2017 to December 2018 were retrospectively analyzed, 19 patients in double strand titanium cable group, including 13 males and 6 females, aged from 26 to 67 years old; Rockwood classification:10 cases of type Ⅲ, 4 cases of type Ⅳ and 5 cases of type Ⅴ;8 cases of traffic injury and 11 cases of fall injury;the time from injury to operation was 3 to 6 days. There were 20 patients in steel plate group, including 15 males and 5 females, aged from 25 to 71 years old. Rockwood classification:11 cases of type Ⅲ, 4 cases of typeⅣ, 5 cases of type Ⅴ;7 cases of traffic injury, 13 cases of fall injury;the time from injury to operation was 2 to 7 days. The length of incision, operation time, intraoperative blood loss, cost, VAS score before and after operation, and Constant-Murley score before and after operation were compared between two groups. Postoperative X-ray films were taken to observe the reduction and maintenance of acromioclavicular joint dislocation. Complications were recorded.@*RESULTS@#Thirty-six patients were followed up for 12 to 14 months. The amount of intraoperative blood loss in the two groups was basically the same. The operation incision in double strand titanium cable group was shorter, the operation time in steel plate group was shorter, and the operation cost in double strand titanium cable group was less. One week and one year after operation, the pain of double strand titanium cable group was less than that of steel plate group. One year after operation, the Constant-Murley score of double strand titanium cable group was higher than that of steel plate group. The postoperative X-ray showed that the acromioclavicular joint in double strand titanium cable group was well reduced, and there was 1 case with slight reduction loss. In the plate group, there was no reduction loss after removal of the clavicular hook plate, and 8 patients had distal clavicular bone atrophy or acromion bone resorption. In steel plate group, 4 cases had long-term postoperative pain, postoperative dysfunction and other complications.@*CONCLUSION@#The clinical effect of coracoclavicular ligament reconstruction with double strand titanium cable is better than that of clavicular hook plate in the treatment of severe acute acromioclavicular joint dislocation, with less trauma (no secondary operation) and lower cost.

ABSTRACT

ATP-binding cassette(ABC) transporters are one of the largest protein families in organisms, with important effects in regulating plant growth and development, root morphology, transportation of secondary metabolites and resistance of stress. Environmental stress promotes the biosynthesis and accumulation of secondary metabolites, which determines the quality of medicinal plants. Therefore, how to improve the accumulation of secondary metabolites has been a hotspot in studying medicinal plants. Many studies have showed that ABC transporters are extremely related to the transportation and accumulation of secondary metabolites in plants. Recently, with the great development of genomics and transcriptomic sequencing technology, the regulatory mechanisms of ABC transporters on secondary metabolites have attached great attentions in medicinal plants. This paper reviewed the mechanisms of different groups of ABC transporters in transporting secondary metabolites through cell membranes. This paper provided key theoretical basis and technical supports in studying the mechanisms of ABC transporters in medicinal plant, and promoting the accumulation of secondary metabolites, in order to improve the quality of medicinal plants.

ABSTRACT

The rat osteoarthritis model was replicated by injection of sodium iodoacetate into the knee joint cavity, and the effects of Gancao Fuzi Decoction on rat osteoarthritis and the proteome of articular cartilage were investigated. Sixty SD rats weighing 230-250 g were randomly divided into normal group, model group, glucosamine sulfate group, and Gancao Fuzi Decoction high, medium and low dose groups. Osteoarthritis model was induced by intra-articular injection of sodium iodoacetate(3 mg on each leg) in all groups except the normal group. After modeling, each administration group was given intragastric administration for 1 month. During the administration period, joint pain test and joint width measurement were performed every week to observe the autonomous behavior of rats. Enzyme linked immunosorbent assay(ELISA) method was used to detect the contents of tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β), matrix metalloproteinase-3(MMP-3), and matrix metalloproteinase tissue inhibitor(TIMP-1) in rat joint lavage fluid. Hematoxylin-eosin(HE) staining was used to observe bone and joint morphology. Nano-LC-LTQ-Orbitrap system was used to detect arti-cular cartilage proteins. The results showed that, compared with the model group, Gancao Fuzi Decoction could significantly improve joint pain and joint swelling in osteoarthritis rats, significantly reduce the contents of TNF-α, IL-1β and MMP-3 in the joint cavity la-vage fluid, increase the content of TIMP-1, and relieve inflammatory diseases such as enlarged joint space, rough cartilage edge, different thickness of cartilage layer, and disordered arrangement of chondrocytes. After comparing the proteins between the groups, 273 differential proteins were screened out. KEGG analysis found that the above differential proteins involved 43 signaling pathways such as systemic lupus erythematosus, among which 11 signaling pathways were related to osteoarthritis. The above results indicated that Gancao Fuzi Decoction had a preventive effect on osteoarthritis, and its mechanism of action may be accomplished by regulating the protein expression of osteoarthritis-related signal pathways.

ABSTRACT

@#AIM: To compare the detection rate of axial length(AL)in cataract eyes by Tomey OA-2000 and IOL Master 500, and to evaluate the repeatability of OA-2000 in measuring ocular biometrics parameters. <p>METHODS: A cross-sectional study of 270 cataract eyes was implemented in the ophthalmic outpatient department from July to September 2018. Ocular biometric measurements including AL, keratometry readings(K), anterior chamber depth(ACD), lens thickness(LT), central corneal thickness(CCT), pupil diameter(PD)and white to white(WTW)were performed using OA-2000 and IOL Master 500. The detection rates of AL were calculated and compared between the two devices. <p>RESULTS: AL detection rates of 86.3%(233/270)and 97.0%(262/270)were found by IOL Master 500 and OA-2000 respectively. The mean difference in the measured AL by the two devices was(0.007±0.129)mm, and the 95% limits of agreement(95%<i>LoA</i>)of AL was 0.01(-0.24 to 0.26)mm. OA-2000 demonstrated good repeatability in measuring AL, ACD, K(2.5mm and 3mm pupil diameter), LT and CCT, but not in measuring PD and WTW. <p>CONCLUSION: Both OA-2000 and IOL Master 500 showed good agreement in AL measurement in cataract patients. However, compared with IOL Master 500, OA-2000 has a higher detection rate of AL. OA-2000 not only demonstrates excellent repeatability in ocular biometric measurements including AL, ACD, K, LT and CCT, but also more advantageous for the AL measurement of cataract with heavy lens opacity and subcapsular opacity.

ABSTRACT

Objective:To explore the long-term clinical efficacy and complications of modified spinous process splitting laminoplasty using coralline hydroxyapatite (SLAC).Methods:The patients who underwent SLAC surgery in this hospital from 2005.5 to 2011.7 were included retrospectively. The perioperative data were collected and followed up. A total of 165 cases were included. Among them, there were 115 males and 50 females; the average age was 56.5±11.4 years (range: 26-84 years), and the average follow-up period was 136.5±23.2 months (range: 108-182 months). The modified Japanese Orthopedic Association (mJOA) score, the neck disability index (NDI) score were used to evaluate the clinical symptoms of patients, and follow-up imaging to observe the changes in cervical spine curvature and mobility.Results:In terms of functional score: mJOA score increased from 11.4±2.9 before surgery to 15.0±1.8 in the early postoperative period but dropped to 14.0±2.5 at the last follow-up ( F=77.096, P<0.001), and NDI score decreased from 19.2%±14.4% before surgery to 13.0%±15.0% in the early postoperative period, but it rose to 14.0%±14.9% at the last follow-up ( F=6.915, P<0.001). The improvement rate of mJOA was 63.5% (early postoperatively) and 50.8% (last follow-up). Regarding the curvature of the cervical spine, the C 2-C 7 Cobb angle decreased from 14.8°±9.1° before surgery to 11.1°±10.5°, and it was maintained at the last follow-up (11.0°±10.1°) ( F=1.083, P=0.342). The cervical spine range of motion decreased significantly, mainly because the Cobb angle in the flexion position decreased from -19.8°±13.6° before the operation to -3.7°±10.6° at the last follow-up ( P<0.001). Seventy-two patients (44.0%) had complications after operation. Six patients (3.6%) developed neurological symptoms aggravated during follow-up, and their mJOA decreased by more than 3 points. 62 patients (37.6%) developed axial symptoms, of which 7 cases were relieved early (within 6 months post-op), 55 patients had persisted symptom and 17 cases (10.3%) remained painful. C 5 nerve root palsy occurred in 10 cases (6.1%) after the operation, 9 cases resolved within two years and the last patient did not resolve. Conclusion:SLAC surgery can effectively alleviate the patient's neurological symptoms and maintain long-term efficacy and cervical lordosis. The occurrence of persistent axial symptoms and the loss of cervical flexion range are long-term complications after SLAC surgery.

ABSTRACT

Objective:To investigate the effect of NEMO binding domain peptide (NBDP) on lung inflammation and apoptosis in mice with acute respiratory distress syndrome (ARDS) and its mechanism.Methods:Thirty-six male BALB/c mice were divided into normal saline (NS) control group, ARDS model group, NBDP negative control group and 6, 12 and 18 μg NBDP pretreatment group by random number table method, with 6 mice in each group. ARDS mouse model was reproduced by aerosol inhalation lipopolysaccharide (LPS) 50 μL. An equivalent among of NS was inhaled in NS control group. The mice in NBDP negative control group were inhaled the materials similar to the non-functional NBDP 30 minutes before the aerosol inhalation LPS; 6, 12 and 18 μg of NBDP 50 μL were respectively inhaled in NBDP pretreatment groups. After inhalation of LPS for 6 hours, mice were sacrificed to get lung tissue and observe the degree of pathological injury and edema. Western blotting was used to detect the phosphorylation of nuclear factor-κB (NF-κB) pathway related proteins [NF-κB inhibitor (IκB) kinaseα/β(IKKα/β), IκBα and NF-κB p65; p-IKKα/β, p-IκBα, p-p65] and the expression of caspase-3 in lung tissue. The bronchoalveolar lavage fluid (BALF) was collected and the levels of inflammatory markers such as myeloperoxidase (MPO), interleukins (IL-1β, IL-8), and tumor necrosis factor-α (TNF-α) were detected by enzyme linked immunosorbent assay (ELISA).Results:ARDS model group had severe edema and hemorrhage, alveolar structure destruction, pulmonary hemorrhage and hyaline membrane formation etc. under light microscope, consistent with the pathological characteristics of ARDS lung tissue, suggesting that the ARDS model was successfully reproduced. ELISA showed that MPO, IL-1β, IL-8 and TNF-α levels of BALF in ARDS model group were obviously higher than those in NS control group. There were no significant differences in the above inflammatory indicators between NBDP negative control group and ARDS model group. The levels of MPO, IL-1β, IL-8 and TNF-α in NBDP pretreatment groups were significantly lower than those in ARDS model group in a dose-dependent manner, especially in 18 μg NBDP, the differences were statistically significant as compared with ARDS model group [MPO (ng/L): 393.32±19.35 vs. 985.87±101.50, IL-1β (ng/L): 43.05±5.11 vs. 97.68±10.88, IL-8 (ng/L): 84.64±2.32 vs. 204.00±17.37, TNF-α (ng/L): 229.13±17.03 vs. 546.73±62.72, all P < 0.05]. Western blotting showed that p-IKKα/β, p-IκBα, p-p65 and caspase-3 protein expressions in ARDS model group were significantly higher than those in NS control group. There was no significant difference in above NF-κB pathway and apoptosis-related protein expression between the NBDP negative control group and ARDS model group. The p-IKKα/β, p-IκBα, p-p65 and caspase-3 protein expression in NBDP pretreatment groups were significantly lower than those in ARDS model group in a dose-dependent manner, especially in 18 μg NBDP, the differences were statistically significant as compared with ARDS model group [p-IKKα/β protein (p-IKKα/β/β-actin): 0.15±0.02 vs. 0.42±0.04, p-IκBα protein (p-IκBα/β-actin): 0.10±0.01 vs. 0.93±0.30, p-p65 protein (p-p65/β-actin): 0.22±0.05 vs. 1.37±0.21, all P < 0.05]. Conclusion:NBDP can inhibit inflammatory response and apoptosis in ARDS lung tissue in a dose-dependent manner, and its mechanism is associated with interference NF-κB signaling pathway transduction.

ABSTRACT

@#Objective    To compare the effect on postoperative immune function between da Vinci robot-assisted thoracoscopic surgery (RATS) and video-assisted thoracoscopic surgery (VATS) , and to provide clinical support for more effective surgical procedures. Methods    A total of 90 patients undergoing radical resection of pulmonary carcinoma in our hospital from June to November 2019 were included. There were 49 males and 41 females with an average age of 62.67 (37-84) years. Among them, 50 patients underwent da Vinci robot-assisted thoracoscopic surgery (a RATS group) and 40 patients underwent video-assisted thoracoscopic surgery (a VATS group). The perioperative indexes as well as postoperative inflammatory factors and immune level effects between the two groups were compared. Results    Compared with the VATS, RATS could significantly shorten the operation time and decrease intraoperative blood loss (P<0.05). RATS also effectively reduced the increase of postoperative inflammatory factor level (P<0.05). But there was no significant difference in postoperative immune function between the RATS group and the VATS group (P>0.05). Conclusion    RATS is superior to VATS in the treatment of non-small cell lung cancer in perioperative indicators and inflammatory factors.

ABSTRACT

@#Objective    To explore the factors that affect the drainage time of da Vinci robot lung cancer surgery, to analyze the coping strategies, and to provide a basis for shortening the drainage time of patients after surgery and speeding up the patients' recovery. Methods    The clinical data of 131 patients who underwent da Vinci robot lung cancer surgery at the Department of Thoracic Surgery, General Hospital of Northern Theater Command from January 2019 to October 2019 were retrospectively analyzed. Among them, 68 were males and 63 were females, with an average age of 59.84±9.66 years. According to the postoperative thoracic drainage time, the patients were divided into two groups including a group A (drainage time≤ 5 days) and a group B (drainage time >5 days). Univariate analysis and logistic multivariate regression analysis were used to analyze the factors that may affect postoperative drainage time, and the correlation between different influencing factors and thoracic drainage time after da Vinci robot lung cancer surgery. Results    Logistic multivariate analysis showed that age≥60 years (P=0.014), diabetes mellitus (P=0.035), operation time≥130 min (P=0.018), number of lymph node dissections≥15 (P=0.002), and preoperative albumin<38.45 g/L (P=0.010) were independent factors affecting the drainage time of da Vinci robot lung cancer surgery. Conclusion    For elderly patients with diabetes mellitus during the perioperative period, blood glucose should be actively controlled, reasonable surgical strategies should be formulated to ensure the safety and effectiveness of the operation, while reducing intraoperative damage and shortening the operation time. After the operation, patients should be guided to strengthen active coughing, expectoration and lung expansion. Thereby it can shorten drainage time and speed up the recovery of patients after operation.

ABSTRACT

Depression is a common mental illness with mood disorders as the main clinical feature. In recent years numerous studies have shown that mitochondrial function and structure are abnormal in patients with depression, and changes in mitochondrial ultrastructure can lead to energy metabolism disorders in the body. It is suggested that 'mitochondrial energy metabolism disorder' may be the pathogenesis of depression. This paper reviews the intrinsic association of mitochondrial energy metabolism with depression and notes potential mechanisms from the standpoint of mitochondrial structure and function on the molecular level. We provide a reference for understanding the pathogenesis of depression and identifying the possible targets of antidepressant drugs.

ABSTRACT

Background: Human infections with zoonotic coronaviruses (CoVs), including severe acute respiratory syndrome (SARS)-CoV and Middle East respiratory syndrome (MERS)-CoV, have raised great public health concern globally. Here, we report a novel bat-origin CoV causing severe and fatal pneumonia in humans. Methods: We collected clinical data and bronchoalveolar lavage (BAL) specimens from five patients with severe pneumonia from Jin Yin-tan Hospital, Wuhan, Hubei province, China. Nucleic acids of the BAL were extracted and subjected to next-generation sequencing. Virus isolation was carried out, and maximum-likelihood phylogenetic trees were constructed. Results: Five patients hospitalized from December 18 to December 29, 2019 presented with fever, cough, and dyspnea accompanied by complications of acute respiratory distress syndrome. Chest radiography revealed diffuse opacities and consolidation. One of these patients died. Sequence results revealed the presence of a previously unknown β-CoV strain in all five patients, with 99.8–99.9% nucleotide identities among the isolates. These isolates showed 79.0% nucleotide identity with the sequence of SARS-CoV (GenBank NC_004718) and 51.8% identity with the sequence of MERS-CoV (GenBank NC_019843). The virus is phylogenetically closest to a bat SARS-like CoV (SL-ZC45, GenBank MG772933) with 87.6–87.7% nucleotide identity, but is in a separate clade. Moreover, these viruses have a single intact open reading frame gene 8, as a further indicator of bat-origin CoVs. However, the amino acid sequence of the tentative receptor-binding domain resembles that of SARS-CoV, indicating that these viruses might use the same receptor. Conclusion: A novel bat-borne CoV was identified that is associated with severe and fatal respiratory disease in humans.

ABSTRACT

@#Objective    To analyze risk factors for chronic cough after minimally invasive resection of non-small cell lung cancer (NSCLC) and explore the possible prevention measures. Methods    A total of 128 NSCLC patients who received minimally invasive resection in 2018 in our hospital were enrolled, including 63 males and 65 females with an average age of 60.82±9.89 years. The patients were allocated into two groups: a robot-assisted thoracic surgery (RATS) group (56 patients) and a video-assisted thoracic surgery (VATS) group (72 patients). Chronic cough was assessed by visual analogue scale (VAS), meanwhile, other perioperative indicators were compared between the two groups. Univariate and multivariate logistic regression analyses were performed to identify risk factors for postoperative chronic cough and explore the prevention strategies. Results    Overall, 61 (47.7%) patients were diagnosed with chronic cough after surgery, including 25 (44.6%) patients in the RATS group and 36 (50.0%) patients in the VATS group, and the difference was not statistically significant (P>0.05). Compared with the VATS group, the RATS group got shorter endotracheal intubation time (P=0.009) and less blood loss (P<0.001). The univariate analysis showed that age (P=0.014), range of surgery (P=0.021), number of dissected lymph nodes (P=0.015), preoperative cough (P=0.006), endotracheal intubation time (P=0.004) were the influencing factors for postoperative chronic cough. The multivariate analysis showed that age <57 years (OR=3.006, 95%CI 1.294-6.986, P=0.011), preoperative cough (OR=3.944, 95%CI 4.548-10.048, P=0.004), endotracheal intubation time ≥172 min (OR=2.316, 95%CI 1.027-5.219, P=0.043), lobectomy (OR=2.651, 95%CI 1.052-6.681, P=0.039) were the independent risk factors for chronic cough. Conclusion    There is no statistical difference in postoperative chronic cough between the RATS and VATS groups. The RATS group gets less blood loss and shorter endotracheal intubation time. Patients with younger age (<57 years), preoperative cough, lobectomy, and longer duration of endotracheal intubation (≥172 min) are more likely to have chronic cough after surgery.
