Objective To explore effect of Wenyang Qudu formula on serum inflammatory factors and immune index in patients with severe infections.Methods A total of 86 severe infection patients admitted to the Third People's Hospital of Henan Province from January to December 2023 were selected as the research subjects.According to the patient file order,odd numbers were the study group,and even numbers were the control group,with 43 cases in each group.The control group was treated with cefoperazone sulbactam sodium,while the study group was treated with Wenyang Qudu formula in addition to the control group[drug composition:Prepared aconite(first decocted)30 g,Poria cocos 30 g,White peony 15 g,Red peony 15 g,Stir fried atractylodes macrocephala 30 g,Dried ginger 9 g,Roasted licorice 9 g,Cassia twig 15 g,Semen lepidii 15 g,Dragon's bone 15 g,Raw oyster 15 g,Codonopsis pilosula 12 g,Angelica sinensis 12 g,Asarum 3 g,Schisandra chinensis 6 g,and Jujube 12 g].Brew in water,and took one dose daily,once in the morning and once in the evening,for a continuous period of 7 days.The differences in the scores of traditional Chinese medicine symptoms such as fever,dyspnea,frequent urination,urgency,and degree of sputum production,serum levels of interleukin-10(IL-10),C-reactive protein(CRP),eosinophils(EOS),and immune function indicators[immunoglobulin E(IgE),CD3+,CD4+,CD8+,CD4+/CD8+]were compared between two groups after treatment,and observed the occurrence of adverse reactions.Results After treatment,the traditional Chinese medicine symptom scores(fever,dyspnea,frequent urination and urgency,degree of sputum production),as well as IL-10,CRP,EOS levels,IgE,and CD8+ were significantly reduced in both groups compared to before treatment,CD3+,CD4+,and CD4+/CD8+ were significantly increased compared to before treatment.In addition,the study group had significantly lower scores of fever,dyspnea,frequent urination and urgency,degree of sputum production,IL-10,CRP,EOS levels,IgE,and CD8+ compared to the control group(fever score:1.36±0.30 vs.2.57±0.46,dyspnea score:1.22±0.31 vs.2.26±0.75,urinary frequency and urgency score:1.30±0.39 vs.2.33±0.82,degree of sputum production:1.19±0.77 vs.2.51±0.85,IL-10(ng/L):9.03±1.67 vs.10.51±2.40,CRP(mg/L):4.68±1.33 vs.7.82±2.53,EOS(×109/L):0.30±0.04 vs.0.46±0.10,IgE(mg/L):104.62±10.73 vs.135.68±14.64,CD8+:0.228±0.016 vs.0.258±0.020,all P<0.05],the levels of CD3+,CD4+,and CD4+/CD8+ were significantly higher than those in the control group(CD3+:0.636±0.044 vs.0.567±0.055,CD4+:0.537±0.054 vs.0.397±0.045,CD4+/CD8+:1.76±0.51 vs.0.55±0.39,all P<0.05].After treatment,it was discovered that the study group had not experienced any adverse reactions,while the control group had 1 case of nausea and vomiting and 1 case of chest tightness.There was no statistically significant difference in the incidence of adverse reactions between the study group and the control group[0(0/43)vs.0.05%(2/43),P>0.05].Conclusion The Wenyang Qudu formula can reduce the serum factor levels of IL-10,CRP,and EOS in critically infected patients,and improve immune function with good safety.

Objective To summarize the experience of minimally invasive tracheotomy under veno-venous extracorporeal membrane oxygenation(VV-ECMO)in 4 cases of severe pneumonia,and to provide examples for airway management of severe pneumonia patients.Methods A retrospective study method was conducted.Four cases of severe pneumonia patients who underwent extracorporeal membrane oxygenation(ECMO)at the intensive care unit(ICU)of Shandong Provincial Hospital Affiliated to Shandong First Medical University from November 2022 to March 2023 were selected as the study subjects,clinical data on the general conditions,imaging examinations before and after admission to ICU,changes in biochemical indexes before and after ECMO technique,and the performance of bedside minimally invasive tracheotomy were collected.Bedside tracheotomy was performed to assist ventilation for patients according to the change of condition.The changes and prognosis of the patients were observed.Results Four patients with severe pneumonia were treated with bedside tracheotomy-assisted ventilation in the state of continuous VV-ECMO,the oxygen saturation was maintained between 0.98-1.00,the airway was cleared and sputum evacuation was smooth,the vital signs were stable after the operation,and the machine was gradually withdrawn.Conclusion During the treatment of severe pneumonia,the safe and rapid completion of bedside minimally invasive tracheotomy in patients with severe pneumonia under continuous VV-ECMO is a new challenge shared by doctors and nurses of otorhinolaryngology,head and neck surgery,and critical care emergency care unit.The four successful cases of bedside tracheotomy after VV-ECMO treatment we report suggest that bedside minimally invasive tracheotomy can safely and rapidly assist airway management,and may provide more useful experiences for the treatment of severe pneumonia and possible new acute respiratory infectious diseases in the future.

Objective:To investigate the perioperative total blood loss of robot-assisted total knee arthroplasty (TKA).Methods:A total of 60 patients with knee osteoarthritis who underwent initial unilateral TKA in Peking Union Medical College Hospital from February to June 2022 were retrospectively analyzed. According to whether they received robot-assisted surgery, they were divided into robot-assisted group and traditional surgery group. In the robot-assisted group, there were 32 patients, including 6 males and 26 females, aged 70.22±5.88 years (range, 57 to 79 years). Left side 14 cases, right side 18 cases; grade of Kellgren-Lawrence: 1 case of grade Ⅱ, 14 cases of grade Ⅲ, 17 cases of grade Ⅳ. In the traditional surgery group, there were 28 patients, including 5 males and 23 females, aged 68.61±6.79 years (range, 57 to 87 years). Left side 16 cases, right side 12 cases; grade of Kellgren-Lawrence: 2 cases of grade Ⅱ, 12 cases of grade Ⅲ, 14 cases of grade Ⅳ. There was no significant difference in baseline data between the two groups ( P>0.05). Postoperative hemoglobin, hematocrit, and their decreased values were recorded in the two groups, and perioperative range of motion (ROM) of knee and Hospital for Special Surgery (HSS) scores were compared between the two groups. Results:All patients successfully completed the surgery and were followed up, with a follow-up time of 9.93±0.83 months (range, 8-11 months) in the robotic-assisted group and 9.59±0.97 months (range, 8-11 months) in the traditional surgery group. The application time of tourniquet in the robot-assisted group was 96.19±10.21 min, which was higher than that in the traditional surgery group (62.68±16.54 min), and the difference was statistically significant ( t=9.57, P<0.001). The total perioperative blood loss in the robot-assisted group was 534.59(411.85, 859.26) ml, which was higher than 411.32(313.42, 613.52) ml in the traditional surgery group, and the difference was statistically significant ( Z=-2.37, P=0.018). There were no significant differences in hemoglobin or hematocrit between the two groups at day 1 and 3 after surgery ( P>0.05). The hemoglobin decrease value in the robotic-assisted group was 19.63±9.73 g/L, which was greater than 14.71±5.84 g/L in the traditional surgery group, and the difference was statistically significant ( t=2.40, P=0.020). The decrease value of hematocrit in the robot-assisted group was 5.77%±3.14%, which was greater than 4.09%±1.57% in the traditional operation group ( t=2.56, P=0.013). At the last follow-up, knee ROM of the two groups were 123.03°±5.91° and 125.82°±6.59°, respectively, which were higher than the preoperative values of 95.69°±11.64° and 90.29°±23.08°. Postoperative HSS scores were 89.50±4.19 points and 90.70±4.34 points, which were higher than 62.58±10.52 points and 61.09±12.66 points before operation, the differences were statistically significant ( P<0.05), and there was no significant difference between groups ( P>0.05). There were 6 cases of postoperative deep vein thrombosis of the lower extremities in the robot-assisted group and 2 cases in the traditional surgery group, and the difference was not statistically significant (χ 2=0.88, P=0.348). Conclusion:Compared with traditional TKA, robotic-assisted TKA increased perioperative blood loss, and there was no difference in postoperative knee function between the two groups.

In order to further strengthen the training and management of clinical teachers, broaden the career development channels of clinical teachers, and truly stimulate their teaching enthusiasm and initiative, this study further classifies clinical teachers according to the principle of the Snell model, focuses on the training of educational clinicians, and explores the training mechanism of teaching talents in line with the actual development needs of hospitals affiliated to universities from the aspects of selection, training, incentive, and assessment. The results of practice show that related practices have a good effect, and the mean number of teaching achievements was 1.98 for the 56 educational physicians, which was 3.9 times that for non-educational physicians. The per capita teaching achievements of educational physicians tended to increase every year compared with those of non-educational physicians. The training path for educational physicians provides useful experience for the construction of clinical teaching team and the high-quality development of education and teaching, and at the same time, it is necessary to further strengthen the dynamic adjustment of talent echelon, the improvement of operating mechanism, and the introduction of new technology.

  Objective  To understand the current status of surgical treatment for hemophilia osteoarthropathy (HO) in China.  Methods  Using an online questionnaire, select domestic hospitals that partici-pated in the compilation of the 'Guideline for perioperative management of hemophilia patients undergoing orthopaedic surgery in China ', in addition to members of the National Joint Surgery Group, and the Orthopedic Branch of the Chinese Medical Association for targeted investigation and analysis.  Results  A total of 17 domestic hospitals were included, all of which were general hospitals. Hospitals that started HO surgery treatment before 2000 accounted for 35.29%. A total of 3057 surgical cases of HO were reported by those hospitals. The most commonly performed surgical procedures were hip and knee joint replacement. The most commonly used coagulation factor replacement regimen was recombinant coagulation factor preparation. Ten hospitals reported finding patients with transfusion-related infectious diseases. Bleeding and hematoma formation were the most frequently reported surgical complications. Excessive length of hospital stay and high economic costs were the most frequently reported problems.  Conclusions  Surgical treatment for HO in 17 hospitals is mainly carried out in some large comprehensive medical centers in the eastern region. Compared with the patient base, the popularity and number of surgeries are still relatively insufficient. It is necessary to further standardize the treatment system by standardizing factor replacement and strengthening rehabilitation to improve surgical treatment outcomes.

Objective    To investigate the surgical strategies and clinical efficacy of transmitral septal myectomy in the treatment of recurrent left ventricular outflow tract obstruction (LVOTO) after alcohol septal ablation. Methods    The clinical data of patients with recurrent LVOTO after alcohol septal ablation from July 2020 to July 2021 in the Department of Cardiac Surgery, Guangdong Provincial People's Hospital were retrospectively analyzed. Patients were preoperatively evaluated by echocardiography, cardiac magnetic resonance imaging, cardiac computed tomography, 3D modeling and printing technology. A personalized surgical strategy was preoperatively developed according to multimodality imaging assessment, while visual exploration was performed on the digital model and simulated surgical resection was performed on the printed model. Results     Two female patients were enrolled, aged 62 years and 64 years, respectively. Totally endoscopic transmitral extended myectomy was successfully performed on both patients with aortic cross-clamping time of 96 min and 85 min, respectively. LVOTO was relieved immediately (subaortic peak pressure gradient decreased from 100 mm Hg to 4 mm Hg and from 84 mm Hg to 6 mm Hg, respectively) and the mitral regurgitation significantly improved after the procedure. No patient had complete atrioventricular block or required permanent pacemaker implantation. The patients were discharged uneventfully without postoperative complications. Conclusion    Personalized totally endoscopic transmitral extended myectomy combined with multimodality imaging assessment and 3D modeling and printing has an acceptable clinical effect in patients with recurrent LVOTO after alcohol septal ablation. The procedure can precisely resect the hypertrophic septal myocardium while avoiding serious complications such as septal perforation or complete atrioventricular block.

Objective:To explore the effect of multiple integration correction training for articulation disorder in children with functional alalia disorders (FAD) .Methods:From January 2020 to June 2021, 68 children with FAD who received language function training in the Affiliated Huaian First People 's Hospital of Nanjing Medical University were selected by convenience sampling. The children were divided into control group and observation group with the method of random number table, 34 cases each. The control group received routine speech training, while the observation group received multiple integration correction training for articulation disorder on the basis of the control group. The motor function of articulation organs, articulation syllable assessment results and speech function recovery were compared between the two groups before intervention (T1) , three months after intervention (T2) and six months after intervention (T3) . Results:After intervention, the longest articulation time, head control, lip strength, tongue extension range, left and right lip swing power of the observation group were higher than those of the control group, with statistical differences ( P<0.05) . At T1, T2 and T3, there were interaction, inter group and time effects in the assessment results of articulation syllables of children in the two groups, and the differences were statistically significant ( P<0.05) . The scores of the modified Frenchay Dysarthria Assessment (FDA) in the two groups had interaction, inter group and time effects, and the differences were statistically significant ( P<0.05) . Conclusions:In FAD children, the implementation of multiple integration correction training for articulation disorder can improve the motor function of articulation organs and the ability of articulation syllable repetition, thereby promoting the recovery of the children's speech function.

Objective:To investigate the relationship between dosimetric parameters and tumor volume change after 125I implantation for thyroid cancer and obtain better dosimetric parameters that predict the curative effect more accurately. Methods:A total of 22 consecutive patients with thyroid cancer (23 targets) who received 125I interstitial brachytherapy in Department of Oncology, Hebei General Hospital were retrospectively analyzed. All the patients received post-operative dose verification, and the D 90 (Minimum dose received by 90% target volume) was calculated. After a regular follow-up, the tumor volume reduction ratio after t months (R t) , actual absorbed dose (D 1m) , efficacy corrected absorbed dose (D 1e) , and sensitivity corrected absorbed dose (D 1s) of the first month were calculated according to the actual follow-up CT images. The statistical test was carried out by SPSS21.0. The Spearman linear analysis was applied to analyze the relationship between D 90, D 1m, D 1e, D 1s and R t, and the curve fitting was also completed. Results:The post-operative D 90, D 1m, D 1e, D 1s and R t were (129.73±14.22) Gy, (36.95±7.35) Gy, (43.45±11.32) Gy, (41.78±13.39) Gy, and (32.00±19.00) %, respectively. And the correlation coefficient were 0.692, 0.551, 0.728, and 0.858, respectively, which showed significant positive relevance between dosimetric parameters and tumor volume change ( P<0.01) , the curve fitting presented cubic function. Conclusion:The post-operative D 90, D 1m, D 1e, and D 1s can be predictors for curative effect, and D 1s is the best predictor.

Objective:To explore the performance of the commonly used whole blood C-reactive protein (CRP) detection systems and give related recommendation on the performance requirements of detection systems.Methods:A total of 7 540 venous blood samples from 26 maternal, child and children′s hospitals were collected to conduct this multi-center study on the analytical performance of 5 commonly used whole blood CRP detection systems from March to April in 2019. The blank check, carryover, repeatability, intermediate precision, linearity, sample stability, influence of hematocrit/triglyceride/bilirubin, comparison with SIEMENS specific protein analyzer and trueness were evaluated. The 5 systems included BC-5390CRP autohematology analyzer, AstepPLUS specific protein analyzer, Ottoman-1000 Automated Specific Protein POCT Workstation, i-CHROMA Immunofluorometer equipment Reader and Orion QuikRead go detecting instrument. The 5 systems were labeled as a, b, c, d and e randomly.Results:Within the 5 systems, all values of blank check were less than 1.00 mg/L, the carryovers were lower than 1.00%. The repeatability of different ranges of CRP concentrations including 3.00-10.00, 10.00-30.00 and>30.00 mg/L were less than 10.00%, 6.00% and 5.00%, respectively, and the intermediate precision was less than 10.00%. The linearity correlation coefficients of the 5 systems were all above 0.975, while the slope was within 0.950-1.050. Whole blood samples were stable within 72 hours both at room temperature (18-25 ℃) and refrigerated temperature (2-8 ℃). The CRP results were rarely influenced by high triglyceride or bilirubin, except for the immmunoturbidimetric test based on microparticles coated with anti-human CRP F(ab) 2 fragments. When triglyceride was less than 15.46 mmol/L, the deviation of CRP was less than 10.00%. When bilirubin was less than 345.47 μmol/L, the deviation of CRP was less than 10.00%. CRP was more susceptible to Hct on the systems without Hct correction. The deviation of CRP between different Hct dilution concentration and 40% dilution concentration can reach as high as 67.48%. The correlation coefficients ( r) of 5 systems were all more than 0.975 in the range of 0-300.00 mg/L compared with Siemens specific protein analyzer. All systems passed the trueness verification using the samples with specified values of 12.89 and 30.60 mg/L. Conclusion:The performance of 5 systems can basically meet the clinical needs, but it is suggested that the whole blood CRP detection system without automatic Hct correction should be modified manually.

As one of the most lethal diseases, pancreatic cancer shows a dismal overall prognosis and high resistance to most treatment modalities. Furthermore, pancreatic cancer escapes early detection during the curable period because early symptoms rarely emerge and specific markers for this disease have not been found. Although combinations of new drugs, multimodal therapies, and adjuvants prolong survival, most patients still relapse after surgery and eventually die. Consequently, the search for more effective treatments for pancreatic cancer is highly relevant and justified. As a newly re-discovered mediator of gasotransmission, hydrogen sulfide (H
