ObjectiveTo observe the effectiveness and safety of modified Taohong Siwu Decoction （桃红四物汤） for patients of chronic heart failure with lower limb deep vein thrombosis in the chronic stage of blood stasis syndrome. MethodsA total of 120 patients of chronic heart failure with lower limb deep vein thrombosis in chronic stage of blood stasis syndrome were randomly divided into 60 cases each in control group and observation group. Both groups were given basic treatment of western medicine， and the observation group was additionally given modified Taohong Siwu Decoction （桃红四物汤） for oral administration， one dose per day. The treatment course for both groups lasted for 4 weeks. The total effective rate and the incidence of adverse reactions were compared between the two groups after treatment. Cardiac function indexes including left ventricular ejection fraction （LVEF）， and left ventricular end-systolic internal diameter （LVESd）， left ventricular end-diastolic internal diameter （LVEDd）， serological indexes including N-terminal natriuretic natriuretic peptide precursor （NT-proBNP）， high sensitivity C-reactive protein （hs-CRP） and vascular endothelial growth factor （VEGF）， score of traditional Chinese medicine （TCM） symptom including chest pain， swelling of the affected limb， fixed tenderness， and bruising， haemodynamics indicators including high cut whole blood viscosity， low cut whole blood viscosity， and erythrocyte pressure， and coagulation indices including activated partial thromboplastin time （APTT）， plasminogen time （PT）， and fibrinogen （FIB） levels were compared before and after treatment. ResultsDuring the study， 3 cases were excluded and 2 cases lost follow-up in the observation group， while 2 cases were excluded and 3 cases lost follow-up in the control group. A total of 110 patients completed the trial， 55 cases in each of the two groups. The total effective rate in the observation group was 92.73% （51/55）， which was significantly higher than that of the control group， 78.18% （43/55， P＜0.05）. Compared within group before treatment， LVEF， APTT and PT levels increased， LVESd， LVEDd， NT-proBNP， hs-CRP， VEGF， high cut whole blood viscosity， low cut whole blood viscosity， erythrocyte pressure volume and FIB levels decreased， chest pain， swelling of the affected limbs， stationary pressure pain and bruising score decreased in both groups after treatment， and the improvement of all above indexes was better in the observation group than that in control group （P＜0.05 or P＜0.01）. The incidence of adverse reactions was 7.27% （4/55） in the observation group and 21.82% （12/55） in the control group， and the incidence of adverse reactions in the observation group was significantly lower than that in the control group （P＜0.05）. ConclusionModified Taohong Siwu Decoction （桃红四物汤） as adjuvant treatment for patients of chronic heart failure with lower limb deep vein thrombosis in the chronic stage of blood stasis syndrome showed better clinical effectiveness when compared with western basic treatment， which can improve the clinical symptoms， cardiac function， haemodynamics， and coagulation， with good safety.

BACKGROUND: Lung cancer is currently the most prevalent malignancy and the leading cause of cancer deaths worldwide. Although the early stage non-small cell lung cancer (NSCLC) presents a relatively good prognosis, a considerable number of lung cancer cases are still detected and diagnosed at locally advanced or late stages. Surgical treatment combined with perioperative multimodality treatment is the mainstay of treatment for locally advanced NSCLC and has been shown to improve patient survival. Following the standard methods of neoadjuvant therapy, perioperative management, postoperative adjuvant therapy, and other therapeutic strategies are important for improving patients' prognosis and quality of life. However, controversies remain over the perioperative management of NSCLC and presently consensus and standardized guidelines are lacking for addressing critical clinical issues in multimodality treatment. METHODS: The working group consisted of 125 multidisciplinary experts from thoracic surgery, medical oncology, radiotherapy, epidemiology, and psychology. This guideline was developed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. The clinical questions were collected and selected based on preliminary open-ended questionnaires and subsequent discussions during the Guideline Working Group meetings. PubMed, Web of Science, Cochrane Library, Scopus, and China National Knowledge Infrastructure (CNKI) were searched for available evidence. The GRADE system was used to evaluate the quality of evidence and grade the strengths of recommendations. Finally, the recommendations were developed through a structured consensus-building process. RESULTS: The Guideline Development Group initially collected a total of 62 important clinical questions. After a series of consensus-building conferences, 24 clinical questions were identified and corresponding recommendations were ultimately developed, focusing on neoadjuvant therapy, perioperative management, adjuvant therapy, postoperative psychological rehabilitation, prognosis assement, and follow-up protocols for NSCLC. CONCLUSIONS This guideline puts forward reasonable recommendations focusing on neoadjuvant therapy, perioperative management, adjuvant therapy, postoperative psychological rehabilitation, prognosis assessment, and follow-up protocol of NSCLC. It standardizes perioperative multimodality treatment and provides guidance for clinical practice among thoracic surgeons, medical oncologists, and radiotherapists, aiming to reduce postoperative recurrence, improve patient survival, accelerate recovery, and minimize postoperative complications such as atelectasis.

Azvudine and nirmatrelvir/ritonavir (Paxlovid) are recommended for COVID-19 treatment in China, but their safety and efficacy in the elderly population are not fully known. In this multicenter, retrospective, cohort study, we identified 5131 elderly hospitalized COVID-19 patients from 32,864 COVID-19 patients admitted to nine hospitals in Henan Province, China, from December 5, 2022, to January 31, 2023. The primary outcome was all-cause death, and the secondary outcome was composite disease progression. Propensity score matching (PSM) was performed to control for confounding factors, including demographics, vaccination status, comorbidities, and laboratory tests. After 2:1 PSM, 1786 elderly patients receiving azvudine and 893 elderly patients receiving Paxlovid were included. Kaplan-Meier and Cox regression analyses revealed that compared with Paxlovid group, azvudine could significantly reduce the risk of all-cause death (log-rank P = 0.002; HR: 0.71, 95% CI: 0.573-0.883, P = 0.002), but there was no difference in composite disease progression (log-rank P = 0.52; HR: 1.05, 95% CI: 0.877-1.260, P = 0.588). Four sensitivity analyses verified the robustness of above results. Subgroup analysis suggested that a greater benefit of azvudine over Paxlovid was observed in elderly patients with primary malignant tumors (P for interaction = 0.005, HR: 0.32, 95% CI: 0.18-0.57) compared to patients without primary malignant tumors. Safety analysis revealed that azvudine treatment had a lower incidence of adverse events and higher lymphocyte levels than Paxlovid treatment. In conclusion, azvudine treatment is not inferior to Paxlovid treatment in terms of all-cause death, composite disease progression and adverse events in elderly hospitalized COVID-19 patients.

Objective:To validate and compare the value of the Status Epilepticus in Pediatric Severity Score (STEPSS) versus PEDSS in assessing the short-term prognosis of children with status epilepticus (SE).Methods:Clinical data of 152 children with SE hospitalized at the First Affiliated Hospital of Zhengzhou University from January 2020 to December 2022 were retrospectively analyzed.According to the STEPSS and PEDSS scores, children with SE were scored and their prognosis was predicted.Receiver operating characteristic (ROC) curves of the 2 scales in assessing the short-term prognosis of SE in children were plotted, and the area under the curve (AUC), optimal cut-off, sensitivity and specificity were calculated, thus validating and comparing the value of the STEPSS versus PEDSS in assessing the short-term prognosis of children with SE.Results:Of the 152 children with SE, 90 were male and 62 were female, with the age of (5.8±3.9) years (1 month to 15 years). There were 112 cases with good prognosis and 40 cases with poor prognosis, involving 13 deaths.The AUC of STEPSS and PEDSS scores in predicting the death in children with SE were 0.908(95% CI: 0.848-0.967) and 0.887(95% CI: 0.831-0.942), respectively, both with the optimal cut-off value of 4.The sensitivity of STEPSS and PEDSS scores in predicting the death in children with SE were 0.740 and 0.846, respectively, and the specificity were 0.745 and 0.835, respectively.There was no significant difference in predicting the death in children with SE between the 2 scales ( P>0.05). In predicting adverse outcomes, the AUC of the STEPSS and PEDSS scores were 0.869(95% CI: 0.800-0.937) and 0.926(95% CI: 0.873-0.979), respectively, both with the optimal cut-off value of 3.The sensitivity of STEPSS and PEDSS scores in predicting adverse outcomes in children with SE were 0.827 and 0.900, respectively, and the specificity were 0.732 and 0.866, respectively.There was significant difference in predicting the adverse outcomes in children with SE between the 2 scales ( P<0.05). Conclusions:Compared with the STEPSS, the PEDSS has a higher application in predicting the short-term treatment outcome of children with SE, which can be used as a routine method to assess the prognosis of children with SE.

Objective To compare the safety and clinical efficacy of lesion removal combined with percutaneous pedicle screw fixation with classical posterior lesion removal in the treatment of lumbar brucelli spondylitis(LBS)by unilateral biportal endoscopic technique with transforaminal lumbar interbody fusion(UBE-LIF)technique.Methods The clinical data of 32 patients with LBS admitted by the Department of Spine and Orthopedics of Gansu Provincial Hospital of Traditional Chinese Medicine from January 2020 to January 2022 were retrospectively analyzed,and the clinical data of the 32 LBS patients were divided into 15 cases in the UBE-LIF group and 17 cases in the posterior group.The general data,surgery-related indexes,and postoperative pathological HE staining of the two groups were recorded and analyzed.The patients'clinical recovery was assessed according to their erythrocyte sedimentation rate(ESR)and C-reactive protein(CRP),low back pain visual analogue score(VAS),Japanese Orthopaedic Association(JOA)score,and Oswestry Dysfunction Index(ODI)preoperative,1 week after surgery,1,3,6 months and 1 year after surgery.Lumbar lordosis angle(LL)and intervertebral space height(DH)were measured by imaging before surgery and at the last follow-up,and intervertebral bone graft fusion was assessed using Suk grading criteria.Results Both groups successfully completed the operation and no serious postoperative complications occurred.There were no significant differences in gender,age,surgical segment,operation time,preoperative ESR and CRP,preoperative VAS,JOA score and ODI index,preoperative LL and DH(P＞0.05).The intraoperative blood loss,postoperative drainage,postoperative getting out of bed,and postoperative hospital stay in UBE-LIF group were significantly lower than those in the posterior group(P＜0.001).Pathological examination of diseased tissues was performed during surgery,all of which was consistent with brucellosis changes.Patients in both groups were followed up for 12-18 months,with an average of 14.8 months.The VAS,JOA score,and ODI index at all postoperative time points in the two groups were significantly improved compared with the preoperative period(P＜0.05).The difference between the two groups was significantly greater than that in the postoperative group:VAS score was lower in UBE-LIF group than in the posterior group(P＜0.01),CRP in both groups was higher than that in the preoperative group,and the elevation level was significantly lower in UBE-LIF group than in the posterior group(P＜0.001).There was no significant difference in ESR between the two groups compared with that before surgery(P＞0.05).There were no significant differences in VAS,JOA score,ODI index,CRP or ESR between the remaining time points after surgery(P＞0.05).At the last follow-up,imaging examination showed that the overall fusion rate of intervertebral bone graft in UBE-LIF group was 93.3％and 94.1％in the posterior group,without significant difference(x2=0.246,P=0.884).LL and DH were significantly improved in both groups compared with preoperative ones(P＜0.01),and the two groups did not significantly differ before and after surgery(P＞0.05).Conclusion Both surgical treatments for LBS are safe effect.Compared with posterior lesion removal bone graft fusion internal fixation,UBE-LIF technology combined with percutaneous pedicle screw internal fixation has the advantages of clear intraoperative vision,less blood loss,faster early postoperative recovery,and shorter postoperative hospital stay,and thus is a feasible surgical method for the minimally invasive treatment of LBS.

Objective To investigate the efficacy and safety of subretinal fluid extraction combined with intravitreal conbercept and gas injection in treating polypoidal choroidal vasculopathy(PCV)complicated with serous retinal pigment epithelium detachment(sPED).Methods From July 2019 to February 2021,13 patients(13 eyes)with PCV complicated with sPED who were treated with subretinal fluid extraction combined with intravitreal injection of conbercept and gas in the Weifang Eye Hospital were selected.All affected eyes received at least 3 times(once a month)of intravitreal anti-vas-cular endothelial growth factor(VEGF)(ranibizumab)injections before the surgery,and the treatment was ineffective.The changes in best corrected visual acuity(BCVA),central retinal thickness(CRT),macular foveal PED height and width before and 1 week,1 month,3 months and 6 months after the operation were observed,and the intraoperative and postop-erative complications were recorded.Results The BCVA of the affected eyes 1 week after operation was better than that before operation,and the difference was statistically significant(Z=-3.237,P=0.001).The CRT of the affected eyes at 1 week,1 month,3 months and 6 months after the operation were thinner than that before the operation,and the differ-ence was statistically significant(Z=-3.180,-3.180,-3.110 and-3.180,P=0.001,0.001,0.002 and 0.001).The height and width of PED at 1 week,1 month,3 months and 6 months after the operation were lower than those before the operation,and the differences were statistically significant(all P＜0.05).Thirteen eyes received an average of(4.15±1.40)intravitreal injections(ranibizumab)before the surgery,and the treatment duration was(5.92±3.95)months(equivalent to one injection every 6 weeks).During the 6-month follow-up,13 eyes received an average of(2.31±1.97)intravitreal injections(conbercept)(equivalent to once every 10 weeks).Partial correlation analysis showed a weak positive correla-tion between the increase in BCVA and the decrease in CRT 6 months after operation(r=0.416,P=0.203).There was no significant correlation between the increase in BCVA and the changes in PED height and width 6 months after operation(r=0.218,0.209,P=0.520,0.538).At 1 month after the operation,9 eyes had PED recurrence or different degrees of retinal nerve subepithelial effusion,and PED improved after repeated intravitreal injection of conbercept.At 6 months after opera-tion,subfoveal PED completely disappeared in 3 eyes,and the retina was completely reattached.There was still active exu-dation in the retina of 1 eye.No systemic or severe ocular complications occurred in 13 eyes during the follow-up period.Conclusion Subretinal fluid extraction combined with intravitreal injection of conbercept and gas in the treatment of PCV complicated with sPED can safely and effectively reduce CRT,improve PED,and reduce the damage to the retina caused by long-term PED,but it has no significant effect on the improvement of BCVA at 6 months after the operation.

OBJECTIVE: To investigate the clinical application of high-frequency color Doppler ultrasound (HFCDU) in detecting perforators in the deep adipose layers for harvesting super-thin anterolateral thigh flap (ALTF). METHODS: Between August 2019 and January 2023, 45 patients (46 sides) with skin and soft tissue defects in the foot and ankle were treated, including 29 males and 16 females, aged from 22 to 62 years, with an average of 46.7 years. The body mass index ranged from 19.6 to 36.2 kg/m ², with an average of 23.62 kg/m ². The causes of injury included traffic accident injury in 15 cases, heavy object crush injury in 20 cases, mechanical injury in 8 cases, heat crush injury in 1 case, and chronic infection in 1 case. There were 20 cases on the left side, 24 cases on the right side, and 1 case on both sides. After thorough debridement, the wound size ranged from 5 cm×4 cm to 17 cm×11 cm. All patients underwent free super-thin ALTF transplantation repair. HFCDU was used to detect the location of the perforators piercing the deep and superficial fascia, as well as the direction and branches of the perforators within the deep adipose layers before operation. According to the preoperative HFCDU findings, the dimensions of the super-thin ALTF ranged from 6 cm×4 cm to 18 cm×12 cm. The donor sites of the flaps were directly sutured. RESULTS: A total of 55 perforators were detected by HFCDU before operation, but 1 was not found during operation. During operation, a total of 56 perforators were found, and 2 perforators were not detected by HFCDU. The positive predictive value of HFCDU for identifying perforator vessels was 98.2%, and the sensitivity was 96.4%. Among the 54 perforators accurately located by HFCDU, the orientation of the perforators in the deep adipose layers was confirmed during operation. There were 21 perforators (38.9%) traveled laterally and inferiorly, 12 (22.2%) traveled medially and inferiorly, 14 (25.9%) traveled laterally and superiorly, 5 (9.3%) traveled medially and superiorly, and 2 (3.7%) ran almost vertically to the body surface. Among the 54 perforators accurately located by HFCDU, 35 were identified as type 1 perforators and 12 as type 2 perforators (HFCDU misidentified 7 type 2 perforators as type 1 perforators). The sensitivity of HFCDU in identifying type 1 perforators was 100%, with a positive predictive value of 83.3%. For type 2 perforators, the sensitivity was 63.2%, and the positive predictive value was 100%. The surgeries were successfully completed. The super-thin ALTF had a thickness ranging from 2 to 6 mm, with an average of 3.56 mm. All super-thin ALTF survived, however, 1 flap experienced a venous crisis at 1 day after operation, but it survived after emergency exploration and re-anastomosis of the veins; 1 flap developed venous crisis at 3 days after operation but survived after bleeding with several small incisions; 3 flaps had necrosis at the distal edge of the epidermis, which healed after undergoing dressing changes. All 45 patients were followed up 6-18 months (mean, 13.6 months). Three flaps required secondary defatting procedures, while the rest had the appropriate thickness, and the overall appearance was satisfactory. CONCLUSION Preoperative application of HFCDU to detect the perforator in the deep adipose layers can improve the success and safety of the procedure by facilitating the harvest of super-thin ALTF.

Objective To investigate whether discontinuous sleep supplementation can reduce myocardial ischemia-reperfusion injury in diabetic rats aggravated by circadian rhythm disorder.Methods The rats were injected intra-peritoneal with 1％streptozotocin(STZ)30 mg/kg combined with high-fat and high-glucose diet to replicate diabetic model.Forty diabetic rats were randomly divided into four groups with 10 in each:sham surgery group(Sham group),ischemia-reperfusion group(I/R group),in which the left anterior descending coronary artery(LDA)was ligated for thirty minutes and reperfusion for 2 h,circadian rhythm disorder group(Crd group,24 h daily light and food),discontinuous sleep supplementation group(Dss group,every 3 hours of illumination and 1.5 hours break at night).We analyzed the myocardial infarct size(by 2,3,5-triphenyltetrazolium chloride stai-ning),determined serum creatine kinase-myoglobin(CK-MB)activity and cardiac troponinⅠ(cTnⅠ)concentrations;the expression level of BMAL1 and REV-ERBα was determined by Western blot.Results Compared to the sham group,the I/R group showed a significantly increased in myocardial infarct size,serum CK-MB activity and cTnⅠ concentration.The expression of the myocardial biological clock gene BMAL1 was down-regulated,while the ex-pression of REV-ERBα was up-regulated(P<0.05).Compared to the I/R group,the Crd group showed a signifi-cantly increase in myocardial infarct size,serum CK-MB activity and cTnⅠ concentration.The expression of the myocardial biological clock gene BMAL1 was down-regulated,while the expression of REV-ERBα was up-regulated(P<0.05).Compared to the Crd group,Dss group showed a significantly decrease in the myocardial infarct size,serum cTn concentration and CK-MB activity.Furthermore,there was an increased protein expression of BMAL1 and a decrease of REV-ERBα(P<0.05).Conclusions Discontinuous sleep supplementation can reduce myocardial is-chemia-reperfusion injury in diabetic rats aggravated by circadian rhythm disorder.

Tuberculosis (TB) is an infectious disease caused by Mycobacterium tuberculosis complex and is mainly manifested as pulmonary tuberculosis. Mycobacterium tuberculosis is characterized by high pathogenicity and drug resistance due to its high viability and lethality, and multidrug-resistant tuberculosis caused by it has become a global public health problem. Early and effective treatment is essential to prevent the emergence of drug-resistant strains. Commonly employed methods for the screening and diagnosis of TB include: clinical signs, imaging examinations (chest X-ray, computed tomography), sputum culture (L-J medium, BACTEC liquid culture system), and immunological tests (lipoarabinomannan antigen test, tuberculin skin test, interferon-gamma release test). In recent years, emerging molecular diagnostic methods such as GeneXpert MTB/RIF assay, loop-mediated isothermal amplification (LAMP), linear probe assay, and whole-genome sequencing have been used to diagnose and characterize TB. These methods not only identify Mycobacterium tuberculosis but also detect mutation sites associated with resistance to first-line anti-tuberculosis drugs (isoniazid, rifampicin, etc.), providing new possibilities for the diagnosis of drug-resistant Mycobacterium tuberculosis. In this paper, the advantages and disadvantages of some commonly used detection methods for tuberculosis are first reviewed, aiming at assisting clinicians to diagnose and treat the disease in a timely manner. Secondly, this paper explores the prospects of the latest high-throughput detection methods for drug-resistant Mycobacterium tuberculosis.
