Objective:To investigate the effects of intravascular hypothermia combined with early post-pyloric feeding on the neurological function and prognosis in patients with severe ischemic stroke, and to provide a theoretical basis for clinical decision-making on the optimal nutritional support strategy for patients with severe ischemic stroke during intravascular hypothermia treatment.Methods:This was a retrospective, non-randomized, controlled study. A total of 78 patients with first severe ischemic stroke who were admitted to the ICU of Neurology Department, Xuanwu Hospital, Capital Medical University from January 2018 to December 2021 were selected. General information and clinical data of the patients were collected and grouped according to intrvascular hypothermia combined with nutritional support. Patients were divided into early post-pyloric feeding group of 52 cases and early parenteral nutrition group of 26 cases. The neurological prognosis, disease prognosis, nutritional status and complications related to nutritional support of the two groups were retrospectively analyzed.Results:The Glasgow score at 30th day after intravascular hypothermia in the early postpyloric feeding group was (11.25 ± 4.92) points, which was higher than that in the early parenteral nutrition group (8.40 ± 5.53), and the difference was statistically significant ( t=-2.45, P<0.05). After treatment, the serum total protein and hemoglobin of early postpyloric feeding group were (59.56 ± 5.09) g/L and (131.06 ± 19.58) g/L, respectively, which were higher than those of early parenteral nutrition group (56.52 ± 7.94) g/L and (122.07 ± 17.72) g/L. The difference was statistically significant ( t=-2.03, -1.91, P<0.05). The clinical pulmonary infection score of the early postpyloric feeding group was (7.33 ± 0.96) points, which was lower than that of the early parenteral nutrition group (9.42 ± 2.11). The mechanical ventilation time and ICU stay time were (17.46 ± 10.47) days and (28.89 ± 12.59) days, respectively. Compared with the early parenteral nutrition group (25.77 ± 15.20) days and (37.07 ± 17.15) days, the differences were statistically significant ( t=3.28, 2.83, 2.52, all P<0.05). There were no significant differences in catheter-associated bloodstream infection and ICU hospitalization mortality between the two groups (both P>0.05). Conclusions:Intravascular hypothermia combined with early post-pyloric feeding can improve the nutritional status of patients with severe ischemic stroke, effectively control pulmonary infection, shorten mechanical ventilation and hospital stay, and promote neurological repair.

Anti-neutrophil cytoplasmic antibody-associated vasculitis with gastrointestinal bleeding as the main symptom: a case report and literature review / 中华危重病急救医学

Anti-neutrophil cytoplasmic antibody-associated vasculitis (AAV) has a wide range of symptoms, and it is difficult for clinicians to make a quick and correct diagnosis. On November 11, 2021, a 36-year-old male patient with AAV was admitted to the emergency and critical care department of Yichang Central People's Hospital. He was admitted to the emergency intensive care unit (EICU) with gastrointestinal symptoms (abdominal pain, black stool) as the main physical signs, and was initially diagnosed as AAV with gastrointestinal hemorrhage (GIH). No bleeding point was found after repeated gastroscopy and colonoscopy. Abdominal emission CT (ECT) showed diffuse hemorrhage in the ileum, ascending colon and transverse colon. Multi-disciplinary consultation in the whole hospital considered the diffuse hemorrhage caused by small vascular lesions in the digestive tract caused by AAV. Pulse therapy with methylprednisolone 1 000 mg/d and immunosuppressive therapy with cyclophosphamide (CTX) 0.2 g/d were administered. The patient's symptoms quickly relieved and transferred out of the EICU. After 17 days of treatment, the patient finally died of massive gastrointestinal bleeding. A systematic review of relevant literatures combined with the case diagnosis and treatment process found that only a minority of AAV patients present with gastrointestinal symptoms as their first symptoms, and patients with GIH were very rare. Such patients had a poor prognosis. This patient delayed the use of induced remission and immunosuppressive agents due to the treatment of gastrointestinal bleeding, which may be the main cause of life-threatening GIH secondary to AAV. Gastrointestinal bleeding is a rare and fatal complication of vasculitis. Timely and effective induction and remission treatment is the key to survival. Whether patients should receive maintenance therapy, the duration of maintenance therapy, and the search for markers of disease diagnosis and treatment response are directions and challenges for further research.

Effects of 10-Week Nordic Hamstring Training on Knee Eccentric Control Angle and Muscle Strength / 医用生物力学

Objective To compare the effects of different support method on eccentric control angle and muscle strength of knee joints in 10-week Nordic hamstring exercise.Methods Twenty-eight college male football players were randomly divided into hand support group (HS group, n=14) and non-hand support group (NHS group, n=14) for 10 weeks. The eccentric control angle and eccentric muscle strength of knee joints were tested before and after the intervention.Results After 10 weeks of Nordic hamstring training, the eccentric control flexion angle of knee joint in HS group and NHS group was significantly decreased by 8° and 10°, and the knee joint angle in NHS group was 12° lower than that in HS group (P<0.05); the peak torque of hamstring and quadriceps femoris in both HS group and NHS group was significantly increased, and the peak torque of hamstring centrifugal motion at 60°/s and 120°/s in NHS group was 16 and 13 N·m higher than that in HS group, respectively (P<0.05).Conclusions NHS group is better than HS group in improving knee flexion angle and centrifugal muscle force. It is suggested that Nordic hamstring training should be taken as one of the daily training tasks for football players to prevent hamstring injury.

Research advances on functional training robots in burn rehabilitation / 中华烧伤杂志

Patients with deep burns are prone to suffer cicatrix hyperplasia or contracture, leading to problems including dysfunction in limbs, which impacts patients' life quality and makes it difficult for them to return to society. Thereby, the rehabilitation treatment after deep burns is particularly important. Currently, exercise therapy plays an important role in burn rehabilitation, which is mainly based on therapies such as continuous manual assistance training and manual stretching practice to provide patients with physical exercise to limbs and to correct the functional dysfunction of limbs in patients. With the continuous progress in technology, functional training robots have been developed to meet the needs. The emergence of functional training robots saves manpower and provides patients refined and standardized functional exercise treatment. From the aspects of production technology and multi-technology integration, this paper mainly introduces the recent innovation and development of functional training robots and the advantages of the application of functional training robots in the field of burn rehabilitation.

Textual Research on Trionycis Carapax / 中国实验方剂学杂志

Trionycis Carapax is a commonly used Chinese medicine in clinical practice. Modern research on Trionycis Carapax mainly focuses on experimental research and clinical observation， which has been rarely reported in the literature. Based on the literature on medicinal herbs， medical books， prescriptions of all dynasties， this study carried out systematic textual research on the historical evolution and changes of the name， origin， producing areas， quality， efficacy， indications， processing methods， and contraindications of the Trionycis Carapax. As revealed by the textual analysis， the origin of Trionycis Carapax is Trionyx sinensis， and the carapace of T. steindachneri is not suitable for the preparation of Trionycis Carapax. The genuine producing areas of Trionycis Carapax include Yueyang， Jingzhou， southeast Anhui， and western Jiangsu in the middle and lower reaches of the Yangtze river. Regarding the quality， the number of ribs of Trionycis Carapax， such as seven ribs and nine ribs， is often used as the quality evaluation standard in ancient Chinese herbal books. However， through literature research and field inspections on the medicinal material markets， it is not advisable to take rib number as a quality evaluation criterion in modern times. With the change of the times， the efficacy and indications of Trionycis Carapax have gradually expanded on the basis of Shennong’s Classic of Materia Medica （Shen Nong Ben Cao Jing）， and later generations widely apply it in internal medicine， surgery， gynecology， pediatrics， etc. It should be noted that the treatment of labor heat and bone steaming by Trionycis Carapax is derived from Shennong’s Classic of Materia Medica， not Treatise on the Nature of Medicinal Herbs （Yao Xing Lun） mentioned in ancient books such as Amplification on Materia Medica （Ben Cao Yan Yi）. The processing methods of Trionycis Carapax are diverse， which are dominated by traditional vinegar processing. In terms of contraindications， Trionycis Carapax should not be compatible with bauxite and marble and is contraindicated in pregnant women. Those with spleen deficiency， weak stomach， and liver deficiency without heat should use it with caution. This study is expected to provide the basis for radical reform and further development and clinical utilization of Trionycis Carapax.

Data Mining and Systems Pharmacology to Elucidate Effectiveness and Mechanisms of Chinese Medicine in Treating Primary Liver Cancer / 中国结合医学杂志

OBJECTIVE@#To identify specific Chinese medicines (CM) that may benefit patients with primary liver cancer (PLC), and to explore the mechanism of action of these medicines.@*METHODS@#In this retrospective, singlecenter study, prescription information from PLC patients was used in combination with Traditional Chinese Medicine Inheritance Supports System to identify the specific core drugs. A system pharmacology approach was employed to explore the mechanism of action of these medicines.@*RESULTS@#Taking CM more than 6 months was significantly associated with improved survival outcomes. In total, 77 putative targets and 116 bioactive ingredients of the core drugs were identified and included in the analysis (P<0.05). A total of 1,036 gene ontology terms were found to be enriched in PLC. A total of 75 pathways identified from Kyoto Encyclopedia of Genes and Genomes were also enriched in this disease, including fluid shear stress, interleukin-17 signaling, signaling between advanced glycan end products and their receptors, cellular senescence, tumor necrosis factor signaling, p53 signaling, cell cycle signaling, steroid hormone biosynthesis, T-helper 17 cell differentiation, and metabolism of xenobiotics by cytochrome. Docking studies suggested that the ingredients in the core drugs exert therapeutic effects in PLC by modulating c-Jun and interleukin-6.@*CONCLUSIONS@#Receiving CM for 6 months or more improves survival for the patients with PLC. The core drugs that really benefit for PLC patients likely regulates the tumor microenvironment and tumor itself.

Mechanism of gasdermin D on intestinal injury in severe acute pancreatitis by mediating pyroptosis / 中华危重病急救医学

Objective:To investigate the function of gasdermin D (GSDMD) in intestinal damage of mice with severe acute pancreatitis (SAP).Methods:The healthy C57BL/6 mice were divided into four groups randomly, including normal saline (NS) group, small interfering RNA (siRNA)-NS group, SAP model group and siRNA-SAP group, with 6 mice in each group. The SAP mouse model was reproduced by intraperitoneal injection of caerulein 50 μg/kg combined with lipopolysaccharide (LPS) 10 mg/kg; the NS group was given the same amount of NS; in the siRNA-SAP group and siRNA-NS group, siRNA 50 mg/kg was injected through the tail vein three times before modeling or injection of NS. The blood of mice eyeball in each group was taken 12 hours after modeling, and serum interleukins (IL-1β, IL-18) levels were detected by enzyme linked immunosorbent assay (ELISA). The mice were sacrificed to observe the general changes in abdominal cavity, the pancreas and ileum tissues were taken to observe the pathological changes under a light microscope. The expression of long-chain non-coding RNA uc.173 (lnc uc.173) was detected by reverse transcription-polymerase chain reaction (RT-PCR). Immunohistochemical method was used to detect the expression of tight junction proteins zonula occluden-1 (ZO-1) and Occludin in intestinal mucosal epithelial cells. Western blotting was used to detect the GSDMD protein expression level in the intestinal tissue.Results:The serum levels of IL-1β and IL-18 in the SAP model group were significantly higher than those in the NS group and the siRNA-NS group [IL-1β (ng/L): 146.66±1.40 vs. 44.48±5.76, 81.49±10.75, IL-18 (ng/L): 950.47±177.09 vs. 115.43±16.40, 84.84±21.90, all P < 0.05]; and the levels of IL-1β and IL-18 in the siRNA-SAP group were significantly lower than those in the SAP model group [IL-1β (ng/L): 116.26±15.54 vs. 146.66±1.40, IL-18 (ng/L): 689.96±126.08 vs. 950.47±177.09, both P < 0.05]. General observation showed that there were no obvious abnormalities in the abdominal cavity of the mice in the NS and siRNA-NS groups; the mice in the SAP model group and the siRNA-SAP group had different degrees of edema and congestion in the intestine; compared with the SAP model group, the abnormalities in the siRNA-SAP group was significantly reduced. Under light microscope, there were no obvious changes in the pancreas and intestinal mucosa in the NS group and the siRNA-NS group; the pancreatic tissue of the SAP model group and the siRNA-SAP group had different degrees of edema, inflammatory cell infiltration, and lobular structure damage, and the intestinal mucosa was damaged to a certain degree, and the villi were broken to varying degrees, but the damage in the siRNA-SAP group was lighter. The results of RT-PCR showed that the expression of lnc uc.173 in the intestinal tissues of the model SAP group was significantly lower than that of the NS group and the siRNA-NS group (2 -ΔΔCt: 0.26±0.12 vs. 1.01±0.37, 0.67±0.32, both P < 0.05), while the expression of lnc uc.173 in the siRNA-SAP group was significantly higher than that in the SAP model group (2 -ΔΔCt: 0.60±0.39 vs. 0.26±0.12, P < 0.05). Immunohistochemistry showed that ZO-1 and Occludin proteins in the NS group were distributed along the epithelial cells of the intestinal mucosa, showing a strong expression; ZO-1 and Occludin expressions were significantly reduced in the SAP model group and siRNA-SAP group, but the expressions in the siRNA-SAP group was higher than that in the SAP model group. Western blotting showed that the expression level of GSDMD protein in the intestinal tissues of the SAP model group was significantly higher than that of the NS group and the siRNA-NS group [GSDMD protein (GSDMD-N/β-actin): 1.99±0.46 vs. 1, 1.00±0.78, both P < 0.05]. Compared with the SAP model group, the expression of GSDMD protein in the siRNA-SAP group was significantly decreased [GSDMD protein (GSDMD-N/β-actin): 1.42±0.42 vs. 1.99±0.46, P < 0.05]. Conclusions:The systemic inflammatory response and intestinal mucosal barrier damage of SAP mice may be related to the increase of GSDMD expression in intestinal tissues. GSDMD mediates cell pyrolysis to promote the release of inflammatory factors, cause intestinal injury, and down-regulate the expression of intestinal epithelial cell tight junction proteins such as ZO-1 and Occludin, resulting in intestinal mucosal damage.

Mechanism of Artesunate in Reversing Epithelial-mesenchymal Transition and Akt /Snail Signaling Pathway in Colorectal Carcinoma / 中国实验方剂学杂志

Objective:To investigate the effects of artesunate （ART） on epithelial-mesenchymal transformation （EMT） of colorectal cancer HCT-8 cells，and explore the effects of ART on cell migration，invasion，EMT ability， and protein kinase B （Akt）/Snail signaling pathway of colorectal cancer. Method:3-（4-5-Dimethylthiazol-2-yl）2，5-diphenyltetrazolium bromide （MTT） assay was used to detect the effects of ART at different concentrations on the proliferation of HCT-8 cells. Wound healing assay and Transwell assay were used respectively to detect the effects of ART on migration and invasion of colorectal cancer cells. The effects of different concentrations of ART on the distribution of EMT-related proteins vimentin and E-cadherin in HCT-8 cells were detected by double-immunofluorescent staining. The effects of ART on protein expression levels of EMT markers E-cadherin，vimentin and N-cadherin in HCT-8 cells and the expression of Akt1， p-Akt1， and Snail1 in the Akt/Snail signaling pathway were determined by Western blot. Result:The dose-dependent inhibitory effects of ART on the proliferation of HCT-8 cells were determined and the inhibition rate was calculated. A dose-response curve was plotted accordingly. The half-maximal inhibitory concentration （IC₅₀） of ART on HCT-8 cells was （16.67±1.95） μmol·L^-1. The following four groups were set up： a control group （0 μmol·L^-1），and low-， medium-， and high-dose ART groups（2， 10， 50 μmol·L^-1）. Compared with the results in the control group，ART inhibited the migration and invasion of HCT-8 cells（<italic>P</italic><0.05）. Specifically， the expression of E-cadherin in HCT-8 cells was significantly up-regulated，and that of vimentin and N-cadherin was significantly down-regulated （<italic>P</italic><0.05）. The expression levels of p-Akt1 and Snail1 were significantly decreased after ART treatment，thus inhibiting EMT（<italic>P</italic><0.05）. Conclusion:The findings of this study suggested that ART inhibited the EMT-triggered migration and invasion of HCT-8 cells presumedly by inhibiting the activation of the Akt/Snail pathway to reverse EMT.

Dynamic Plantar Pressure Features of Ankle Joints at Different Stress Positions / 医用生物力学

Objective To explore the characteristics of plantar pressure of ankle joints at different limb laterality and different stress positions. Methods Twenty-three healthy subjects were recruited to perform walking trails. Each subject was tested for plantar pressure in ankle neutral position, ankle inversion and ankle eversion through simple custom-designed walkways and plantar pressure plate. The evaluation indices were peak pressure, contact area, contact time percentage, M/L (ratio of sum of medial plantar peak pressure to sum of lateral peak pressure), A/P (ratio of sum of toe peak pressure to heel peak pressure). Results The peak pressure of the first metatarsus bone in the dominant foot was significantly larger than that in the non-dominant foot, and the peak pressure of the fifth metatarsus bone was significantly smaller than that on the non-dominant foot. The M/L of dominant side was significantly larger than that of the non-dominant side. Except for the peak pressures of the mid-foot and the first toe, there were significant differences in other regions among the three ankle positions. The percentage of contact time in each area during inversion was greater than that in neutral position, and the percentage of contact time of plantar regions during eversion was longer than that in neutral position except the second toe. The M/L in inversion, neutral and eversion position were 1.24±0.46, 1.06±0.26, 0.88±0.25. The M/L of dominant foot was greater than that of the non-dominant foot, and the A/P during inversion and eversion was greater than that in neutral positions. Conclusions The stability of the dominant foot was better than that of the non-dominant foot. The standing stability decreased during inversion and eversion. During inversion, the body shifted inward and forward to maintain the stability. During eversion, the center of gravity shifted outward and forward to maintain the stability.

Correlation between Adolescent Scoliosis and Biomechanical Factors / 中国康复理论与实践

Objective To study the relationship between adolescent scoliosis and various biomechanical factors. Methods A total of 637 students in grade four to six in a primary school of Zhaoyang District in Zhaotong,Yunnan,Chi-na were screened for scoliosis in December,2016.Finally,a case control study of 19 patients with idiopathic sco-liosis who had been diagnosed by X-ray was carried out.According to the matching criteria,42 students were col-lected as control group.Then,eleven biomechanical factors were analyzed and evaluated in two groups.Those factors included unequal shoulders,cervical lateral flexion,cervical rotation,thoracic lateral flexion,thoracic ro-tation,lumbar lateral flexion,lumbar rotation,lateral tilt of pelvis,anterior and posterior pelvic tilt,leg inequality and flat foot. Eventually, the biomechanical factors were statistically analyzed with binary Logistic regression analysis. Results and Conclusion The unequal shoulders,thoracic rotation,lateral tilt of pelvis,leg inequality and flat foot were the risk factors for scoliosis(P<0.05).Detailed posture assessment should be carried out to find the biomechani-cal factors leading to abnormal posture,and achieve the goals of the more targeted medical intervention for the patients with spinal asymmetry.

Finite element analysis of the effects of individual extralevator abdominoperineal exci-sion of rectal neoplasms in the low posterior wall on the pelvic floor / 中国肿瘤临床

Objective:To evaluate the effects of individual extralevator abdominoperineal excision (ELAPE) of rectal neoplasms in the low posterior wall on the pelvic floor by finite element analysis. Methods:MIMICS 10.01, Geo Magic Studio 12, and ANSYS Workbench 14.0 were used to analyze the magnetic resonance data obtained from the pelvic region of 27 healthy nulliparous volunteers. Three types of finite element models (intact model, ELAPE model, and individual ELAPE model) were developed. The maximal stress on non levator ani tissues were analyzed using the three models, while the maximal stress on levator ani tissues were analyzed using the in-tact model and the individual ELAPE model. Their stress distributions under the same pressure were analyzed and compared. Results:The maximal stress on non levator ani tissues obtained using the intact model, ELAPE model, and individual ELAPE model were (1.963± 0.061), (5.127 ± 0.070), and (3.667 ± 0.126) MPa, respectively, with P<0.01. High-stress zones were obtained at the joints with pelvic walls on both sides using the three models, while the maximal stresses were obtained at the joints with pubis on both sides. The maxi-mal stress on levator ani tissues obtained using the intact model and individual ELAPE model were (0.812 ± 0.042) MPa and (1.437 ± 0.043) MPa, respectively. Thus, the individual ELAPE model yielded higher values of maximal stress compared to the intact model. Both models generated high-stress zones at the joints with tendinous arch of levator ani tissues on both sides, and maximum stresses at the joints with pubis on both sides. Conclusion:Individual ELAPE decreases the stress on non levator ani tissues. This suggests that the risk of postoperative pelvic floor hernia is relatively reduced.

Effects of neuroactive peptide urocortin on STN neuron's spontaneousdischarge and relationship with CRF-2R / 中国药理学通报

Aim To investigate the effects of endocrinal petptide urocortin on subthalamic nucleus (STN) neuron''s discharge, also observe the convergence effect of UCN with dopamine (DA) and glutamate (GLU), so as to understand the regulation effects of UCN and its mechanism in Parkinson''s disease (PD).Methods Forty Sprague-Dawley rats were used in this experiment.Nerve electrophysiology method-microiontophoresis was used to observe the effects of UCN on STN neuron firing rates and firing wave.Astressin (AST, the blocker of CRF receptor 2), protein kinase A (PKA) were used to observe the effects of UCN whether via CRF-2R and PKA signal pathway.Moreover, given UCN during the period of DA and GLU, the effects of UCN on DA and GLU in STN neurons were determined.Results During the period of using the UCN, UCN could inhibit the firing rate of 82％ (27/33) STN neuron (P<0.01), and the firing discharge rates were reduced from(3.65±0.27)Hz to (2.05±0.33) Hz (P<0.01).However, the inhibitory effects of UCN in STN could be antagonized by AST.Given UCN during the period of microiontophoresis of inhibitory neurotransmitter (DA) and excited neurotransmitter (GLU), UCN could enhance the effects of DA and attenuate the excitatory effects of GLU (P<0.01).Conclusion UCN and GLU/DA in STN, UCN play inhibitory and regulated effects on STN neurotransmitters(DA and GLU)via CRF-2 receptor and PKA signal pathway.

Combination of musk and olibanum promotes proliferation of prostate stem cells in mice: An experimental study / 中华男科学杂志

Objective@#To study the effects of muskolibanum combination on the proliferation and differentiation of prostate stem cells.@*METHODS@#We cultured prostate epithelial cells and urogenital sinus mesenchymal (UGSM) cells from 7－10 d old C57BL/6 mice and 16－18 d old pregnant C57BL/6 mice, transplanted the mixed suspension of the two types of cells under the kidney envelope of SCIDCB.17 male mice, and harvested the transplants 30 days later. We randomly divided the SCIDCB.17 mice into four groups to be treated intragastrically with musk (n = 8), olibanum (n = 8), musk+olibanum (n = 7), and normal saline (blank control, n = 8)) respectively, all for 14 days. Then we collected the kidney tissue for observation of the morphology of the glandular tubes and differentiation of different subsets of stem cells by HE staining and determination of the expressions and distribution of P63, CD133, CD117 and Sca1 by immunohistochemistry and Western blot.@*RESULTS@#A system was successfully established for the isolation and mixed culture of Sca1 Lin+ CD49f+ (LSC) cells of prostate stem cells and UGSM cells of the mouse embryonic prostate. Immunohistochemistry showed positive expressions of P63, CD133, Sca1, and CD117 in the prostatic acinar epithelia and proved the presence of prostatic acinar epithelial structure in the transplants. Compared with the blank control group, the expressions of CD133, Sca1 and CD117 were significantly increased in the musk, olibanum, and musk+olibanum groups (P< 0.05), higher in the musk+olibanum than in the musk or olibanum group (P< 0.05), and their protein expressions were even more elevated in the musk+olibanum group (P< 0.01), with statistically significant difference from the olibanum group (P< 0.05).@*CONCLUSIONS@#The combination of musk and olibanum can improve the proliferation and differentiation of prostate stem cells.
