Through consulting herbal medicine， medical books， and local chronicles from past dynasties to modern times， this paper systematically researched Spatholobi Caulis from name， origin， producing areas， harvesting， processing， usage， quality evaluation， functions and indications， providing a reference for the development and utilization of famous classical formulas containing Spatholobi Caulis. According to the research， Spatholobi Caulis was first recorded in the Annals of Shunning Prefecture from the Qing dynasty. It was originally a medicinal herb commonly used in Shunning， Yunnan， and was named from the red juice resembling chicken blood that flowed out after the vein was cut off. The mainstream original plants of each dynasty were Kadsura heteroclita and Spatholobus suberectus. Among them， K. heteroclita mainly focused on dispersing blood stasis and unblocking meridians， mainly treating rheumatic pain and injuries caused by falls or blows， and it is mostly used as the raw material of Jixueteng ointments. S. suberectus was commonly used as decoction pieces in decoction， which had the functions of promoting blood circulation and replenishing blood， activating meridians and collaterals， and mainly used for treating anemia， irregular menstruation， and rheumatic bone pain. The production area of Spatholobi Caulis recorded in the Qing dynasty was Yunnan. Currently， the main production area of S. suberectus is Guangxi， while the main production area of K. interior is Yunnan. In the Qing dynasty， the usage of Spatholobi Caulis was an individual prescription with other herbs before making ointments， which was usually composed of the juice of it， safflower， angelica， and glutinous rice. But in modern times， Spatholobi Caulis is mostly sliced and dried for use. The quality of Spatholobi Caulis is often determined by the number of reddish-brown concentric circles on the cut surface， with a higher number indicating better quality. Additionally， the presence of resinous secretions is also considered desirable. Based on the research findings， it is suggested that when developing famous classical formulas containing Spatholobi Caulis， the choice of the primary source should be S. suberectus or K. heteroclita， taking into consideration the therapeutic effects of the formula. It is also recommended that the latest plant classification be referenced in the next edition of Chinese Pharmacopoeia， adjusting the primary source of Kadsurae Caulis to K. heteroclita to avoid confusion caused by inconsistent original names， and the functions adjust to promote Qi circulation and relieve pain， disperse blood stasis and unblock collaterals， treating injuries caused by falls and bruises.

Objective To compare the application effects of simple artery ligation and modified inflation-deflation method in determining the lung intersegment plane during thoracoscopic precision segmentectomy.Methods A total of 80 patients who underwent thoracoscopic precision segmentectomy in our hospital from August 2021 to February 2023 were prospectively included and divided into the observation group and the control group by random number table method,with 40 cases in each group.Patients in the observation group were determined the lung intersegment plane by simple artery ligation,while patients in the control group were determined the lung intersegment plane by modified inflation-deflation method.The perioperative related indexes,lung function indexes,postoperative complications and follow-up of patients between the two groups were compared.Results The operative time and blood loss of patients in the observation group were significantly shorter/lower than those in the control group(P<0.05).There was no significant difference in the time to reveal the interseg-mental planes, total drainage volume after operation, indwelling time of drainage tube, postoperative hospital stay or lung segmentectomy distribution of patients between the two groups (P>0. 05). The percentage of forced vital capacity to the predicted values (FVC％pred) and percentage of forced expiratory volume in 1 second to the predicted values (FEV1％pred) after operation of patients in the two groups were significantly decreased compared with those before operation (P<0. 05), and FVC％pred and FEV1％pred after operation of patients in the observation group were significantly higher than those in the control group (P<0. 05). There was no statistically significant difference in the occurrence of postoperative complications of patients between the two groups (P>0. 05). There was no death, local recurrence or distant metastasis occurred in all patients during follow-up. Conclusion Compared with the modified inflation-deflation method, the application of simple artery ligation to determine the intersegment plane during thoracoscopic precision segmentectomy has significant advantages such as simple operation, less injury, and less impact on the lung function of patients, which is a feasible and effective technique, with high safety.

Hyperkalemia is one of the common ion metabolism disorders in clinical practice. Hyperkalemia is defined as serum potassium higher than 5.0 mmol/L according to the guidelines at home and abroad. Acute severe hyperkalemia can cause serious consequences, such as flaccid paralysis, fatal arrhythmia, and even cardiac arrest. The use of renin-angiotensin- aldosterone system inhibitors, β-blockers and diuretics, low-sodium and high-potassium diets, and the presence of related comorbidities increase the occurrence of hyperkalemia. Hyperkalemia risk exist in all clinical departments, but there is a lack of a standardization in the management of multi- department cooperation in hospital. Therefore, a number of domestic nephrology and cardiology department experts have discussed a management model for multi-department cooperation in hyperkalemia, formulating the management standard on hospital evaluation, early warning, diagnosis and treatment, and process. This can promote each department to more effectively participate in nosocomial hyperkalemia diagnosis and treatment, as well as the long-term management of chronic hyperkalemia, improving the quality of hyperkalemia management in hospital.

Objective:To discuss the feasibility of control the pulmonary artery (PA) with rumel and bulldog clamp during uniportal thoracoscopic left upper lobectomy.Methods:Retrospective analysis of clinical data of 21 patients whose left PA infiltrated by tumor or lymph nodes.The Rumel was used to proximal control of the left PA, and the endoscopic bulldog clamp to distal control. The left upper lobectomy and PA reconstruction were completed under single-port thoracoscopy.Results:All patients were successfully operated, one patient underwent thymectomy, and one patient underwent left S6a subsegmentectomy at the same time. PA reconstruction was performed by running suture under single-port thoracoscopy in 18 patients, by pericardial patch in 2 patients assisted by small incision, and by circumferential resection in one patient associated with left upper sleeve lobectomy assisted by small incision. The operation time was (213.3±40.5) min, the PA control time was (16.5±4.6) min.The blood loss was (152.9±99.9) ml. Postoperative indwelling time of thoracic drainage tube was (5.3±2.8) days, and the postoperative hospitalization time was (9.1±3.6) days. There were no serious complications during the perioperative period.Conclusion:The PA control technique using rumel and bulldog clamp is reliable and occupies less space, which is helpful for the left upper lobectomy and PA reconstruction under uniportal thoracoscopy

Objective To compare clinical effect between open reduction and fixation with cannulated screw and threaded rivet via posteromedial approach versus arthroscopic Endobutton plate fixation in treating posterior cruciate ligament avulsion fractures.Methods Clinical data of 38 patients with posterior cruciate ligament avulsion fractures from July 2020 to December 2021 were analyzed retrospectively,and divided into open reduction and internal fixation group(posterior medial approach hollow anchor system fixation)and arthroscopic fixation group(Endobutton with loop plate fixation under arthroscopy).There were 20 patients in open reduction and internal fixation group,including 16 males and 4 females,aged from 26 to 74 years old with an average of(42.9±18.8)years old;13 patients on the left side and 7 patients on the right side;12 patients were classi-fied to type Ⅱ and 8 patiens with type Ⅲ according to Meyers-McKeever fractures classification;14 patients were grade Ⅱ and 6 patients were grade Ⅲ in back drawer test.There were 18 patients in arthroscopic fixation group,including 11 males and 7 fe-males;aged from 24 to 70 years old with an average of(53.5±13.4)years old;11 patients on the left side and 7 patients on the right side;10 patients were classified to type Ⅱ and 8 patiens with type Ⅲ according to Meyers-McKeever fractures classifica-tion;11 patients were grade Ⅱ and 7 patients were grade Ⅲ in back drawer test.Operation time,blood loss,and quality of im-mediate reduction were compared between two groups.Knee range of motion,knee back drawer test,and International Knee Documentation Committee(IKDC)grading,KT2000 stability evaluation and Lysholm function score of knee joint were com-pared at 6 months after operation.Results All patients were followed up for 8 to 16 months with an average of(12.3±1.9)months.There were no complications such as incision infection,fracture malunion or non-union,and internal fixation loosening occurred.The avulsion fractures of knee joint were reached to imaging healing standard at 6 months after operation.Operation time and blood loss in open reduction and internal fixation group were(56.4±7.1)min and(63.2±10.2)ml,while(89.9±7.4)min and(27.7±8.7)ml in arthroscopic fixation group,respectively,and had significant difference between two groups(P＜0.05).There were no differences in immediate reduction quality(x2=0.257,P=0.612),knee joint range of motion at 6 months after opertaion(t=0.492,P=0.626),knee joint rear drawer test(x2=0.320,P=0.572),IKDC classification of knee joint(x2=0.127,P=0.938),KT2000stability evaluation(x2=0.070,P=0.791),and knee Lysholmfunction score(t=0.092,P=0.282)between two groups.Conclusion Posterior medial approach with hollow anchoring system fixation and arthroscopic Endobutton with loop plate fixa-tion for the treatment of posterior cruciate ligament tibial occlusion avulsion fracture could achieve satisfactory clinical results,and arthroscopic surgery has less bleeding,but also has a longer learning curve and longer operation time than traditional inci-sion surgery.The surgeon needs to make a choice according to clinical situation of patient and their own surgical inclination.

Objective:To explore the relationship between the expression of cerebellar zinc finger structure 5(ZIC5)protein in breast cancer and its clinicopathological characteristics,surgical prognosis.Methods:A total of 128 breast cancer patients,who were admitted to our hospital be-tween June 2016 and December 2017,were enrolled in this study.Immunohistochemistry was employed to assess the expression of ZIC5 protein.The positive expression rate of ZIC5 protein in breast cancer tissues was compared with that in normal surgical margin tissues.Additionally,an analysis was conducted to explore the association between the expression of ZIC5 protein and various clinical pathological characteristics of breast cancer patients,as well as its correlation with prognosis.Results:The positive expression rate of ZIC5 protein in breast cancer tissue was higher than that in normal tissue of resection margin.The postoperative survival rate of breast can-cer patients was 81.37％.TNM stage Ⅲ～Ⅳ,undifferentiated/poorly differentiated,tumor diam-eter ≥ 2 cm,invasion depth T3～T4,lymph node metastasis,ZIC5 protein positive expression were all risk factors for poor prognosis of breast cancer surgery.(RR=4.405,5.153,4.520,2.211,3.137,6.079,P＜0.05).The survival rate of patients with negative ZIC5 protein expression in breast cancer tissue was higher than that of patients with positive ZIC5 protein expression(P＜0.05).Conclu-sion:The positive expression rate of ZIC5 protein in breast cancer tissue is higher than that in nor-mal tissue of resection margin,and the expression of ZIC5 protein in cancer tissue is related to clinical stage,tumor differentiation,tumor size,invasion depth,and lymph node metastasis.The above indicators are risk factors for poor prognosis of breast cancer surgery.

Objective To compare the clinical application of empirical thoracoscopic segmentectomy and precise segmentectomy planned by artificial intelligence software, and to provide some reference for clinical segmentectomy. Methods A retrospective analysis was performed on the patients who underwent thoracoscopic segmentectomy in our department from 2019 to 2022. The patients receiving empirical thoracoscopic segmentectomy from January 2019 to September 2021 were selected as a group A, and the patients receiving precise segmentectomy from October 2021 to December 2022 were selected as a group B. The number of preoperative Hookwire positioning needle, proportion of patients meeting oncology criteria, surgical time, intraoperative blood loss, postoperative chest drainage time, postoperative hospital stay, and number of patients converted to thoracotomy between the two groups were compared. Results A total of 322 patients were collected. There were 158 patients in the group A, including 56 males and 102 females with a mean age of 56.86±8.82 years, and 164 patients in the group B, including 55 males and 109 females with a mean age of 56.69±9.05 years. All patients successfully underwent thoracoscopic segmentectomy, and patients whose resection margin did not meet the oncology criteria were further treated with extended resection or even lobectomy. There was no perioperative death. The number of positioning needles used for segmentectomy in the group A was more than that in the group B [47 (29.7%) vs. 9 (5.5%), P<0.001]. There was no statistical difference in the number of positioning needles used for wedge resection between the two groups during the same period (P=0.572). In the group A, the nodule could not be found in the resection target segment in 3 patients, and the resection margin was insufficient in 10 patients. While in the group B, the nodule could not be found in 1 patient, and the resection margin was insufficient in 3 patients. There was a statistical difference between the two groups [13 (8.2%) vs. 4 (2.4%), P=0.020]. There was no statistical difference between the two groups in terms of surgical time, intraoperative blood loss, duration of postoperative thoracic drainage, postoperative hospital stay, or conversion to open chest surgery (P＞0.05). Conclusion Preoperative surgical planning performed with the help of artificial intelligence software can effectively guide the completion of thoracoscopic anatomical segmentectomy. It can effectively ensure the resection margin of pulmonary nodules meeting the oncological requirements and significantly reduce the number of positioning needles of pulmonary nodules.

Objective:To determine incidence of seasonal influenza virus infection in the community and to analyze the factors influencing seasonal influenza virus infection.Methods:This study recruited residents aged 6-59 years to build a cohort in 15 villages/streets in Macheng city in November 2019. Meanwhile, a cross-sectional baseline survey was conducted immediately to collect sera, information on demographics and child protection knowledge, behaviors, as well as attitudes using a questionnaire from the participants enrolled in the cohort (i.e., before the influenza epidemic season). In July 2020, a cross-sectional follow-up survey was conducted to collect sera once again (i.e., after the influenza season). Paired sera from the two cross-sectional surveys were tested for influenza virus-specific antibodies by hemagglutination inhibition (HI) test or micro-neutralization (MN) test using a circulating representative strain of each subtype/lineage of influenza virus as the test antigen. The infections with influenza virus subtype/lineage was confirmed if there was a four-fold or more increase in titers of antibodies against circulating representative strain of the subtype/lineage of influenza virus. Factors influencing infection with influenza A (H3N2) and B/Victoria viruses were analyzed using univariable and multivariable logistic regression.Results:In November 2019, 800 study participants were enrolled in the cohort, including 340 children aged 6-17 years and 460 adults aged 18-59 years; 605 study participants (including 224 children and 381 adults) were followed up in July 2020 and their paired sera were obtained before and after the influenza season. 25.3% (153/605) of the participants were confirmed to be infected with at least one subtype/lineage of seasonal influenza virus by HI and MN tests. The overall incidence of influenza viruses of all subtypes/lineages in children was 44.2% (95% CI: 37.6%-50.8%) which was significantly higher than the incidence of 14.1% in adults (95% CI: 10.7%-17.7%). Children had the highest incidence of influenza A (H3N2) virus infection, followed by B/Victoria. MN or HI antibody titers in A (H3N2)[ OR=0.88 (95% CI: 0.84-0.93)] and B/Victoria[ OR=0.97 (95% CI: 0.95-0.99)] before the influenza season were significantly associated with whether children were infected with that subtype/lineage of influenza virus. Conclusions:The residents aged 6-59 years in Macheng city had a substantial incidence of seasonal influenza virus infection during the influenza season from winter 2019 to spring 2020. Notably, almost half of children aged 6-17 years have been infected with seasonal influenza virus. Higher titers of HI/MN antibodies against seasonal influenza virus before the influenza season would be likely to reduce the risk of infection with influenza A (H3N2) and B/Victoria.

Objective To explore the magnetic resonance imaging(MRI)manifestations of acute cerebral infarction(ACI)and the correlation between lipoprotein-associated phospholipase A2(Lp-PLA2),cystatin C(Cys C)and short-term prognosis.Methods A total of 110 ACI patients admitted to the department of neurology in our hospital from January 1,2022 to January 1,2023 were selected as the study objects.The clinical data and multimodal MRI were collected,and the serum Lp-PLA2 and Cys C levels of patients were detected.The patients were divided into the good prognosis group and the poor prognosis group according to the modified Rankin scale(mRS)score 90 days after onset.The predictive value of MRI manifestations and Lp-PLA2 and Cys C levels for short-term poor prognosis was analyzed.Results There were statistically significant differences in the time from onset to admission,National Institute of Health Stroke Scale(NIHSS)score on admission,hypertension or diabetes,coronary heart disease or atrial fibrillation of patients between the good prognosis group and the poor prognosis group(P<0.05).The proportions of patients with ischemic penumbra,HV positive,cortical-subcortical infarction,large perforating branch infarction,small perforating branch infarction,bilateral anterior circulation infarction,posterior circulation infarction,anterior-posterior circulation infarction,middle cerebral artery(MCA)stenosis or occlusion,both internal carotid artery(ICA)and MCA stenosis or occlusion,posterior cerebral artery(PCA)or vertebral artery(VA)stenosis or occlusion and hemorrhage transformation in the poor prognosis group were significantly higher than those in the good prognosis group(P<0.05).The Lp-PLA2 and Cys C levels of patients in the poor prognosis group were significantly higher than those in the good prognosis group(P<0.05).Small penetrating branch infarction,posterior circulation infarction,anterior-posterior circulation infarction,MCA stenosis or occlusion,both ICA and MCA stenosis or occlusion,hemorrhage transformation,serum Lp-PLA2 and Cys C had certain predictive value for patients with short-term poor prognosis(P<0.05).Conclusion MRI manifestations(ischemic penumbra,HV positivity,different types of cerebral infarction,and vascular stenosis)and serum Lp-PLA2 and Cys C levels can predict the short-term prognosis of ACI patients and provide important reference for the formulation of clinical treatment plans.

This study was aimed at analyzing the changes in the cell proteome of HTR-8/Svneo human villous trophoblasts during infection with Listeria monocytogenes,to explore the mechanisms involved in L.monocytogenes infection of the placenta at the molecular level in host cells.Tandem Mass Tag(TMT)proteomics was used to compare the quantitative proteome be-tween the HTR-8/Svneo infection group and control group.The Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)databases were used to analyze enrichment in the molecular functions,biological processes,and metabolic pathways of differentially expressed proteins.A total of 76 285 peptides and 6 979 quantifiable proteins were identified.A total of 356 proteins showed significant differential expression:153 up-regulated and 203 down-regulated.The protein with the high-est fold change was microtubule motor protein(B4DYE2),and the protein with the lowest fold change was translation initia-tion factor 1(Q6IAV3).GO functional enrichment and KEGG metabolic pathway enrichment analyses indicated that the up-regulated proteins were involved primarily in biological processes and metabolic pathways such as the movement of microtubules and microfilament as well as autophagy,whereas the down-regulated proteins were involved mainly in primary metabolic pathways,such as carbon metabolism,nitrogen metabolism,amino acid biosynthesis,and nucleic acid metabolism,as well as ubiquitin mediated protein hydrolysis.In the process of infection of HTR-8/Svneo by L.monocytogenes,the basal metabolism of host cells may be significantly diminished,and the autophagy level may be high.The significant up-regulation of cell migration-inducing and hyaluronan-binding protein CEMIP(Q8WUJ3)suggested an important role of this protein in regulating the migration and invasion of trophoblast cells,thus causing adverse pregnancy outcomes.Our findings may provide new ideas for the study of the molecular mechanism of L.monocytogenes infection of the placenta.
