Pulmonary sarcoidosis is an immune system disease with an unclear etiology. Guided by the yang-reinforcing method， it is believed that the fundamental pathogenesis of pulmonary sarcoidosis lies in the disharmony between water and fire and the reckless movement of the ministerial fire. The failure of the spleen and stomach to maintain warmth， leading to the production of phlegm and blood stasis， is an important pathogenesis. The invasion of external pathogenic toxins， deeply penetrating into the interior， is considered a triggering factor for the disease. The treatment focuses on supplementing the yang， consolidating the kidney， drawing fire back to its source， warming the yang， benefiting the kidney， and nourishing the spleen to generate metal. It also emphasizes unblocking the yang， transforming turbidity， and eliminating phlegm and blood stasis.

Glutamate-ammonia ligase (GLUL, also known as glutamine synthetase) is a crucial enzyme that catalyzes ammonium and glutamate into glutamine in the ATP-dependent condensation. Although GLUL plays a critical role in multiple cancers, the expression and function of GLUL in gastric cancer remain unclear. In the present study, we have found that the expression level of GLUL was significantly lower in gastric cancer tissues compared with adjacent normal tissues, and correlated with N stage and TNM stage, and low GLUL expression predicted poor survival for gastric cancer patients. Knockdown of GLUL promoted the growth, migration, invasion and metastasis of gastric cancer cells in vitro and in vivo, and vice versa, which was independent of its enzyme activity. Mechanistically, GLUL competed with β-Catenin to bind to N-Cadherin, increased the stability of N-Cadherin and decreased the stability of β-Catenin by alerting their ubiquitination. Furthermore, there were lower N-Cadherin and higher β-Catenin expression levels in gastric cancer tissues compared with adjacent normal tissues. GLUL protein expression was correlated with that of N-Cadherin, and could be the independent prognostic factor in gastric cancer. Our findings reveal that GLUL stabilizes N-Cadherin by antagonizing β-Catenin to inhibit the progress of gastric cancer.

This article is based on ZHANG Jingyue's theory of yin-yang holism to explore the etiology， pathogenesis， and treatment of acute exacerbation of rheumatoid arthritis-associated interstitial lung disease （RA-ILD）. It is believed that the foundation of acute exacerbation of RA-ILD lies in real yin insufficiency and yin fail to control yang； external pathogen attacking is a common cause of acute exacerbation of RA-ILD. For treatment， it is important to first suppress ministerial fire by prescribing modified Yinhuo Decoction （引火汤）； if ministerial fire submerged， focus should be on nourishing both yin and yang； if real yin deficiency is the main issue， modified Zuogui Pill （左归丸） should be used； if real yang deficiency is prominent as well， modified Yougui Pill （右归丸） can be chosen. When yin and yang balanced， the disease could be solved.

BACKGROUND:Ankylosing spondylitis is a progressive inflammation of spinal stiffness deformity caused by tissue ossification and fibrosis.The posture of ankylosing spondylitis patients is abnormal and their activities are limited that minor injuries can lead to thoracolumbar fractures.Traditional medical image observation limits doctors'preoperative decision planning and postoperative disease prevention for ankylosing spondylitis treatment. OBJECTIVE:Based on the spinal model of ankylosing spondylitis patients before and after posterior spinal cancellous ossification osteotomy("Y"osteotomy for short),to explore the biomechanical changes of"Y"osteotomy and fixation in the treatment of ankylosing spondylitis. METHODS:Based on the preoperative and postoperative CT images of an ankylosing spondylitis patient who went to the Second Affiliated Hospital of Inner Mongolia Medical University,a three-dimensional spine model(T11-S1)before and after"Y"osteotomy(L3 osteotomy)was reconstructed in Mimics 19.0 software.A 7.5 Nm torque was applied to the top of T11 vertebral body to simulate the movement of the spine under six conditions:flexion,extension,left bending,right bending,left rotation and right rotation.Finally,the range of motion of each vertebral body,the stress of each intervertebral disc,and the stress of the screw rod system were simulated. RESULTS AND CONCLUSION:(1)After"Y"type osteotomy and posterior fixation,the range of motion of all vertebrae in the spine decreased,and the loss rate of upper vertebrae was large(L1:77.95%).(2)The maximum stress of the spinal intervertebral disc before operation occurred at the L1-L2 segment(0.55 MPa),and the maximum stress of the spinal intervertebral disc after operation occurred at the T11-T12 segment(0.50 MPa),and the stress of intervertebral disc below T12 was far less than that before operation.(3)The maximum stress of the screw rod system(166.67 MPa)occurred in the upper and middle segments of the rod body and the root of the pedicle screw.(4)In conclusion,the"Y"type posterior fixation operation enhances the stability of the spine and reduces the range of motion of the spine.The vertebral body decompression of the fixed segment is great and the stress-shielding phenomenon of the lower vertebral body is significant.The stiffness of the rod body and the stress concentration area of the pedicle screw should be strengthened to avoid the fracture of the rod caused by stress fatigue.

The control strategy of rehabilitation robots should not only adapt to patients with different levels of motor function but also encourage patients to participate voluntarily in rehabilitation training.However,existing control strategies usually consider only one of these aspects.This study proposes a voluntary and adaptive control strategy that solves both questions.Firstly,the controller switched to the corresponding working modes(including challenge,free,assistant,and robot-dominant modes)based on the trajectory tracking error of human-robot cooperative movement.To encourage patient participation,a musculoskeletal model was used to estimate the patient's active torque.The robot's output torque was designed as the product of the active torque and a coefficient,with the coefficient adaptively changing according to the working mode.Experiments were conducted on two healthy subjects and four hemiplegic patients using an ankle rehabilitation robot.The results showed that this controller not only provided adaptive the robot's output torque based on the movement performance of patients but also encouraged patients to complete movement tasks themselves.Therefore,the control strategy has high application value in the field of rehabilitation.

Objective To explore the clinical efficacy and safety of early surgical treatment for spinal thoracolumbar fracture without nerve injury.Methods The clinical data of 80 patients with spinal thoracolumbar fracture without nerve injury who were admitted to the department of spinal surgery in our hospital were retrospectively analyzed.According to the different operation timing,those who underwent surgery within 72 hours after fracture were included in the early operation group(n=41),and those who underwent surgery 72 hours to 2 weeks after fracture were included in the elective operation group(n=39).All operations were performed through the Wiltse approach for short-segment pedicle screw fixation on the injured vertebra.The operation time,intraoperative blood loss,hospital stay and incidence of complication of the two groups were compared.The visual analogue scale(VAS)scores,Oswestry disability index(ODI),compression rate of the anterior edge height of the injured vertebra,and the Cobb angle in the sagittal position of the injured vertebra before surgery,1 week after surgery and 1 year after surgery were compared between the two groups.The improvement rates of the anterior edge height compression and the Cobb angle in the sagittal position of the injured vertebra 1 week and 1 year after surgery were compared between the two groups.Results There was no significant difference in the operation time,intraoperative blood loss or total incidence of complications between the two groups(P>0.05).The hospital stay in the early operation group was shorter than that in the elective operation group,and the difference was statistically significant(P<0.05).The VAS scores and ODI 1 week and 1 year after surgery of the two groups were better than those before surgery,and the differences were statistically significant(P<0.05).There was no significant difference in the VAS scores or ODI at each time point before and after surgery between the two groups(P>0.05).The compression rate of the anterior edge height and Cobb angle in the sagittal position of the injured vertebra 1 week and 1 year after surgery in the two groups were lower/smaller than those before surgery,with statistically significant differences(P<0.05).There was no statistically significant difference in the compression rate of the anterior edge height or Cobb angle before surgery in the sagittal position of the injured vertebrae between the two groups(P>0.05).The compression rate of the anterior edge height and Cobb angle in the sagittal position of the injured vertebra 1 week and 1 year after surgery in the early operation group were lower/smaller than those in the elective operation group,and the differences were statistically significant(P<0.05).The improvement rates of the anterior edge height compression and the Cobb angle in the sagittal position of the injured vertebra 1 week and 1 year after surgery in the early operation group were better than those in the elective operation group,and the differences were statistically significant(P<0.05).Conclusion Early surgical treatment for spinal thoracolumbar fracture without nerve damage is safe,it can significantly shorten hospitalization time,obtain good fracture reduction quality and definite therapeutic effects.However,a comprehensive preoperative evaluation of the patients' condition is necessary to ensure surgical safety.

The aim of this study was to clarify the genetic diversity and population history of Ixodes persulcatus in some ar-eas of Inner Mongolia in order to provide accurate data for effective vector control programs and reveal the transmission mecha-nism.Samples were collected in 10 areas of Inner Mongolia during the active tick season(April 2021-July 2023)using the flag-dragging and manual sampling methods.The 16S rRNA and COI gene were sequenced to clarify genetic diversity of I.per-sulcatus.The positivity rates for the COI gene and 16S rRNA were 90.00％and 98.33％respectively.Overall,18 and 15 haplotypes were identified for the COI gene and 16S rRNA,respectively,with a total haplotype diversity＞0.762 and total nucleotide diversity＜0.005.The Tajima's values and Fu's Fs were negative for significance.A nucleotide mismatch map was shown as a single peak.The genetic differentiation index FST of the population indicates a small degree of genetic differ-entiation of the population,while analysis of molecular vari-ance indicates that the variation within populations was greater than between populations.Phylogenetic tree and haplotype network plots showed confounding distributions between hap-lotypes.I.persulcatus from the Hinggan League and Hulun-buir regions can adapt to environmental changes and possess abundant genetic diversity.Genetic differentiation is mainly concentrated within the population and no geographical isolation was observed.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
