Objective To enhance the quality of medical services in the intensive care unit(ICU)of provincial traditional Chinese medicine(TCM)hospitals.Methods In November 2023,Sichuan Provincial Critical Care Medicine Quality Control Center of TCM launched the"quality control supervision project scoring standard for critical care medicine of TCM"to conduct quality control evaluation and business guidance for all TCM hospitals with independent ICU.The survey covered structural indicators,control indicators,participation of TCM,development of new technologies,and diagnosis and treatment programs for dominant diseases.Results In terms of structural indicators:a total of 110 TCM hospitals in the province have independent ICU,an increase of 1.12 times compared with 2019.The control indicators showed that the ICU patients admission rate was higher than that of the national ICU admission rate in 2017,and the admission rate of patients with acute physiology and chronic health evaluation Ⅱ(APACHEⅡ)score≥15 points increased.However,the mortality of ICU exceeded the national average.The implementation of core indicators had been significantly improved,but the incidence of outcome indicators such as ICU ventilator-associated pneumonia(VAP),ICU intravascular catheter-related bloodstream infection(CRBSI),and ICU catheter-related urinary tract infection(CAUTI)had increased since 2019,mainly in secondary hospitals.The average number of new technologies was about(5.5±3.4),the participation rate of TCM decreased,and the dominant diseases increased compared with 2019,mainly sepsis,respiratory failure and hemorrhagic stroke.Conclusions The number of ICU units in TCM hospitals at all levels in Sichuan province has grown rapidly,and key performance indicators have also improved compared to previous periods.However,greater efforts are still needed in preventing the occurrence rates of VAP,CRBSI,and CAUTI.There is a shortage of medical resources allocation,and the imbalance in regional medical resources and professional training remains an urgent issue to be addressed.Additionally,the participation rate of TCM and the dominant diseases need further enhancement.

Objective:To compare the efficacy of cervical decompression performed at different times in the treatment of incomplete cervical spinal cord injury.Methods:A multicenter retrospective cohort study was conducted to analyze the clinical data of 96 patients with incomplete cervical spinal cord injury admitted to six hospitals including Honghui Hospital affiliated to Xi'an Jiaotong University, etc, from May 2018 to May 2021. There were 36 females and 60 males, aged 28-42 years [(35.2±6.7)years]. The injured segments were at C 3 in 7 patients, C 4 in 15, C 5 in 20, C 6 in 23 and C 7 in 31. According to the American Spinal Injury Association (ASIA) scale, there were 59 patients with grade B, 27 grade C, and 10 grade D. A total of 36 patients underwent cervical decompression within 24 hours after injury (early group), 33 patients within 24-72 hours after injury (late group), and 27 patients within 4-14 days after injury (delayed group). The operation time, intraoperative blood loss, postoperative drainage, length of hospital stay, Cobb angle, height of intervertebral space and space occupation of the spinal canal before surgery and at postoperative 3 days, and ASIA score, ASIA motor score, ASIA light tactile score, ASIA acupuncture sensation score, visual analog scale (VAS) score, Japanese Orthopedic Association (JOA) score, neck dysfunction index (NDI) before surgery and at postoperative 3 months, 1 year and at the last follow-up and incidence of complications were compared among the three groups. Results:All the patients were followed up for 12-21 months [(16.4±4.2)months]. There was no significant difference in the operation time among the three groups (all P>0.05). The intraoperative blood loss and postoperative drainage volume in the early group were (312.5±5.2)ml and (165.3±45.8)ml, which were higher than those in the late group [(253.5±40.0)ml, (120.4±60.6)ml] and the delayed group [(267.3±36.8)ml and (130.4±38.6)ml] (all P<0.01). There was no significant difference between the late group and the delayed group (all P>0.05). The length of hospital stay in the early group was (5.2±1.6)days, which was shorter than that in the late group [(7.6±2.3)days] and the delayed group [(8.0±1.3)days] (all P<0.05), but there was no significant difference between the late group and the delayed group ( P>0.05). There was no significant difference in the Cobb angle, height of intervertebral space and space occupation of the spinal canal among the three groups before and at postoperative 3 days (all P>0.05). There was no significant difference in the ASIA score, ASIA motor score, ASIA light tactile score, ASIA acupuncture sensation score, VAS score, JOA score and NDI among the three groups before surgery (all P>0.05). At postoperative 3 months, 1 year and at the last follow-up, the ASIA grading of the early group was better than that of the late group and the delayed group ( P<0.05 or 0.01), but there was no statistically significant difference between the late group and the delayed group (all P>0.05). The ASIA motor scores of the early group were (56.4±4.5)points, (76.3±3.6)points and (85.4±6.5)points at postoperative 3 months, postoperative 1 year and the last follow-up, respectively, which were higher than those in the late group [(52.3±2.4)points, (60.3±8.6)points and (72.3±2.4)points] and the delayed group [(51.9±2.3)points, (62.8±4.6)points and (71.9±1.3)points]; the ASIA light tactile scores of the early group were (70.2±2.9)points, (72.6±4.3)points and (78.3±2.3)points, which were higher than those in the late group [(66.2±3.7)points, (68.3±1.6)points and (73.3±1.6)points] and the delayed group [(65.2±2.1)points, (67.8±1.9)points and (72.3±2.5)points]; acupuncture sensation scores of the early group were (71.9±3.1)points, (80.1±3.8)points and (89.1±7.6)points, which were higher than those in the late group [(67.4±2.7)points, (72.6±3.7)points and (77.9±1.8)points] and the delayed group [(68.3±2.2)points, (72.6±3.1)points and (77.2±1.9)points] (all P<0.05). VAS scores of the early group at postoperative 3 months, 1 year and at the last follow-up were (4.3±0.6)points, (2.4±0.3)points and (1.6±0.2)points, which were lower than those in the late group [(5.1±1.3)points, (4.1±0.6)points and (3.0±0.6)points] and the delayed group [(5.0±1.7)points, (4.0±0.8)points and (3.1±0.2)points]; JOA scores of the early group were (12.8±1.6)points, (14.4±2.6)points and (17.9±3.3)points, which were higher than those in the late group [(11.9±1.9)points, (13.3±1.6)points and (8.9±1.3)points] and the delayed group [(11.6±1.8)points, (13.2±1.4)points and (9.3±2.1)points]; NDI scores of the early group were 12.1±3.3, 10.1±2.1 and 7.3±1.4, which were lower than those in the late group (14.4±3.1, 12.3±1.6 and 8.9±1.3) and the delayed group (14.1±2.3, 12.9±1.9 and 9.5±2.1) (all P<0.05). There was no significant difference in all the above-mentioned scores at postoperative 3 months, 1 year and at the last follow-up between the late group and the delayed group (all P>0.05). The incidence of complications was 25.0% (9/36) in the early group, 27.3% (9/33) in the late group and 37.0% (10/27) in the delayed group (all P>0.05). Conclusion:Compared with within 24-72 hours and 4-14 days after injury, cervical decompression performed within 24 hours after injury for patients with incomplete cervical spinal cord injury can shorten the length of hospital stay, improve the function of the spinal cord nerves and relieve pain, with no increase of the incidence of complications.

【Objective】 To explore the clinical effect of unilateral double-channel endoscope-assisted bone graft fusion and internal fixation (ULIF) in the treatment of recurrent lumbar disc herniation. 【Methods】 The clinical data of 22 patients with recurrent lumbar disc herniation treated by ULIF in our hospital from August 2020 to October 2020 were analyzed retrospectively. The study indicators included intraoperative blood loss, operation time, bed rest time, and hospital stay. The follow-up data included visual analogue score (VAS) of low back pain, Japanese Orthopaedic Association score (JOA), OSwestry disability index (ODI) score, as well as 36 concise health status survey (SF-36) scores before operation, and 1 week and 6 months after operation. 【Results】 The average operation time was (179.15±42.06) minutes, the average intraoperative blood loss was (132.67±41.92) mL, the average bed rest time was (1.51±0.42) days, and the average hospital stay was (4.82±1.13) days. The VAS score of low back pain at 1 week after operation was lower than that before operation (all P<0.000 1), and further decreased during the follow-up. The ODI score, JOA score and SF-36 score of postoperative follow-up were significantly different from those before operation (P<0.05). The satisfaction rate was 86.4% at 1 week after operation and 95.4% at 6 months after operation. The proportion of significant clinical efficacy at 1 week after operation and postoperative 6 months was 18.2% and 63.6%, respectively. 【Conclusion】 ULIF has the advantages of short-term recovery, less intraoperative blood loss, short bed rest and hospital stay, and good medium-term clinical effect. It is a safe and reliable minimally invasive technique for spinal surgeons in the treatment of recurrent lumbar disc herniation.

Objective:To investigate the clinical features and treatment status of immune-related myositis (IRM) caused by immune checkpoint inhibitors (ICIs) in order to improve the diagnosis and treatment rate of the disease.Methods:Two cases of IRM combined with the diagnosis and treatment were described and the literature about IRM in the past 10 years was reviewed, and the clinical data of 59 patients were analyzed.Results:IRM was more common in males, with a total of 47 (79.7%). IRM usually occurred after 45 days of medication or after two doses. The clinical manifestations were mainly myalgia and muscle weakness, which were more common in the limbs. The initial symptoms were ptosis and diplopia. Fifty patients (84.7%) had serum creatine kinase (CK) levels higher than twice the upper limit of normal (UNL). In immunological examinations, 18 patients were found to be positive for anti-rhabdoid muscle antibody (AsM-Ab), while most of the myositisspecific antibodies (MSAs) and myositis-associated antibodies (MAAs) were negative. Thirty-four patients (75.6%) had abnormal EMG, and most patients showed myogenic injury. Muscle magnetic resonance imaging (MRI) showed muscle edema and inflammation in 8 patients. Muscle biopsies from 18 (45.0%) patients showed varying degrees of necrotic myofibers. Fifty-seven patients (96.6%) discontinued ICIs after developing IRM, 54(91.5%) received cortico-steroids, and 20(33.9%) received other treatments including intravenous immuno-globulin (IVIG), plasma exchange.Conclusion:IRM can occur in the early stage of ICIs treatment. Electro-myography, muscle MRI and muscle biopsy in suspicious cases can improve the diagnosis rate of the disease. Early use of corticoteroid, IVIG and other immunotherapy can effectively alleviate the disease.

Objective:To explore the feasibility and clinical effect of the infrared vascular imager in the transplantation of free arterialized venous flaps.Methods:A retrospective analysis was conducted with patient data of hand microsurgery using free arterialized venous flaps to repair hand wounds in the Second Affiliated Hospital of Wenzhou Medical University from March 2019 to November 2020. An arterialized venous flap was designed according to the Goldschlager’s Type Ⅲ flap design with the aid of a magnifying glass following the venous course. The flap was transfer to cover the wound of the recipient area. The reconstructive effect was observed postoperatively, including the blood supply, color, texture, survival of the flap, the flexion and extension of the affected finger, and the appearance of the forearm donor site. The hand function was evaluated by the Chinese Medical Association Hand Surgery Society’s upper limb function evaluation trial standard.Results:A total of 17 patients were included, including 11 males and 6 females, ranging in age from 19 to 68 years old, with an average age of 34.6 years. A total of 18 skin flaps were designed and elevated, and the flap size ranged from 2.0 cm × 3.0 cm to 8.0 cm × 9.0 cm. The patients were followed up 3 to 12 months after the operation, with an average follow-up of 6 months. Blisters appeared on the second day after the operation in 8 flaps, and the affected limbs were raised to maintain the integrity of the blisters. The blisters of the flaps subsided one week after the operation. Congestion occurred on the second day after operation in 7 flaps, which subsided after two weeks after routine treatment, such as raising the affected limb and removing some sutures. One flap developed progressive hypoperfusion one week after the operation, and eventually necrosis. Seventeen flaps survived, and one flap failure was observe. All the surviving skin flaps were free of bloat and had a good appearance. In two cases, the skin graft area was pigmented, and the flexion and extension activities of the affected fingers were suitable. Using the Chinese Medical Association Society of Hand Surgery’s upper limb function evaluation trial standard, 16 patients (excluding one flap failure) were evaluated for hand function, showing 11 cases were excellent and 5 cases were good.Conclusions:Infrared vascular imaging technology enables free arterialized venous flap transplantation to realize non-contact, non-invasive, simple operation, intuitive and accurate, and truly realizes rapid flap design under direct vision. Infrared vascular imaging technology is an effective auxiliary tool for free arterialized venous flap transplantation.

Baylisascaris schroederi,a roundworm(ascaridoid)parasite specific to the bamboo-feeding giant panda(Ailuropoda melanoleuca),represents a leading cause of mortality in wild giant panda populations.Here,we present a 293-megabase chromosome-level genome assembly of B.schroederi to infer its biology,including host adaptations.Comparative genomics revealed an evolutionary trajectory accompanied by host-shift events in ascaridoid parasite lineages after host separations,suggesting their potential for transmission and rapid adaptation to new hosts.Genomic and anatomical lines of evidence,including expansion and positive selection of genes related to the cuticle and basal metabolisms,indicate that B.schroederi undergoes specific adaptations to survive in the sharp-edged bamboo-enriched gut of giant pandas by structurally increasing its cuticle thickness and efficiently utilizing host nutrients through gut parasitism.Additionally,we characterized the secretome of B.schroederi and predicted potential drug and vaccine targets for new control strategies.Overall,this genome resource provides new insights into the host adaptation of B.schroederi to the giant panda as well as the host-shift events in ascaridoid parasite lineages.Our findings on the unique biology of B.schroederi will also aid in the development of prevention and treatment measures to protect giant panda populations from roundworm parasitism.

Objective: To investigate the effect of tripartite motif containing 59(TRIM59) on the biological function of human colorectal cancer HCT116 cells and its possible mechanism. Methods: The recombinant TRIM59 interference plasmid(si-TRIM59) was constructed and transfected into colorectal cancer cell line HCT116 by liposome transfection. The transfection efficiency was verified by RT-qPCR and Western blot. The effects of TRIM59 gene silencing on the proliferation, colony-formation ability and cell cycle of colorectal cancer cells were detected by CCK-8 method, colony formation assays and flow cytometry respectively. Western blot was used to detect the expression level of CDK4 and cyclinD1. Results: The expression levels ofTRIM59mRNA and protein in colorectal cancer cells were significantly higher than those in normal colorectal mucosa cells(P<0. 05). After knockdown of TRIM59expression, the proliferation activity and colony forming ability of HCT116 cells were significantly inhibited(P<0. 05), and the cell cycle was arrested in G0/G1 phase. At the same time, the expression levels of CDK4and CyclinD1 significantly decreased(P<0. 05). Conclusion TRIM59was highly expressed in colorectal cancer cells. Down regulation ofTRIM59expression can inhibit the proliferation and clone formation of colorectal cancer cells, suggesting thatTRIM59may become a new target for gene therapy of colorectal cancer.
