Objective:To compare the surgical outcomes between scarless endoscopic thyroidectomy-lateral neck dissection (SET-LND) and open LND for papillary thyroid cancer (PTC) with lymph node metastasis and to share the experience in the prevention and treatment of lymphatic leakage after LND.Methods:Totally 90 PTC patients (25 males) who underwent LND in the Second Affiliated Hospital of Zhejiang University School of Medicine from Jan. 2021 to Aug. 2022 were retrospectively enrolled, with an average age of (28.06±4.89) years. They were divided into the SET-LND group ( n=50) and the open LND group ( n=40). The intraoperative blood loss, operation time, drainage volume on the first and the second days, postoperative lymphatic leakage, tumor (T), and node (N) were observed. The categorical variable data were compared between groups by χ 2 test, and the continuous variable data confirming normal distribution were compared between groups by independent sample t-test. Results:The operation time of the SET-LND group was (284.00±74.65) min, significantly longer than that of the open LND group (145.38±43.26) min ( t=-10.42, P<0.001). The intraoperative blood loss ( t=-1.309, P=0.194), postoperative hospital stay ( t=-0.136, P=0.892), drainage volume on the first day ( t=-1.074, P=0.286), and drainage volume on the second day ( t=-1.595, P=0.114), postoperative lymphatic leakage ( χ2=0.001, P=0.989), T ( t=0.367, P=0.714), N ( t=-1.614, P=0.110) were not significantly different between the two groups. Conclusion:Two surgical methods of LND have similar therapeutic effects and no significant difference was observed in the incidence of postoperative lymphatic leakage between the two groups.

Lung cancer is the most common malignant tumor of the respiratory system， and its pathogenesis is still not fully understood. Despite the significant clinical efficacy achieved through treatments such as surgery， radiotherapy， chemotherapy， targeted therapy， and immunotherapy， they still come with many complications and significant adverse reactions. In recent years， numerous basic and clinical studies have confirmed the effectiveness of Chinese medicine in treating lung cancer. Chinese medicine features synergistic regulation through its multiple components， targets， pathways， and approaches. Active monomeric constituents in Chinese medicine are diverse， and their mechanisms of action are intricate， making it challenging to fully understand the mechanisms by which Chinese medicine prevents and treats lung cancer. Therefore， there is an urgent need to approach Chinese medicine intervention in lung cancer from a modern medical perspective， exploring the mechanisms of Chinese medicine intervention in lung cancer at the molecular biology and network pharmacology levels. According to traditional Chinese medicine （TCM）， the occurrence of lung cancer is predominantly attributed to factors such as deficiency of healthy Qi， presence of pathogenic factors， internal accumulation of heat-toxins， internal accumulation of phlegm-dampness， and Qi stagnation and blood stasis. Literature analysis reveals that Chinese medicine compound formulas for lung cancer predominantly include tonifying agents and heat-clearing and toxin-removing agents， such as Shashen Maidongtang， Xiaoyan prescription， and Feijinsheng prescription. The single herbs used mainly include heat-clearing， deficiency-tonifying， blood-activating， stasis-resolving， phlegm-resolving， cough-relieving， and asthma-calming categories. The use of Chinese medicine aligns with the TCM understanding of the etiology and pathogenesis of lung cancer. Studies have shown that TCM can regulate the expression of key molecules in lung cancer-related signaling pathways， such as the phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt）， nuclear factor-kappa B （NF-κB）， Wnt/β-catenin， mitogen-activated protein kinase （MAPK）， and Janus kinase/signal transducer and activator of transcription （JAK/STAT）， thereby exerting effects such as reducing lung cancer cell activity， blocking the cell cycle， inhibiting proliferation and invasion of lung cancer cells， inducing apoptosis in lung cancer cells， promoting cell autophagy， and reversing drug resistance， and intervening in the progression of lung cancer. This study systematically summarized recent research progress on how Chinese medicine monomers or formulas regulated the aforementioned signaling pathways and key protein expression to exert anti-lung cancer effects， aiming to elucidate the mechanisms by which Chinese medicine intervenes in the progression of lung cancer and provide insights and theoretical basis for further research and clinical application of Chinese medicine in lung cancer intervention.

ObjectiveTo explore the effect of mentality-controlling on local microcirculation of acupuncture at Hegu （LI 4）. MethodsForty healthy subjects were randomly divided into simple acupuncture group and mentality-controlling acupuncture group， with 20 cases in each group. The simple acupuncture group was acupunctured at Hegu （LI 4） on the right hand of the patient. In mentality-controlling acupuncture group， an audio clip was played to guide the participants to control their mentality when needle retention for 5 min after performing acupuncture twirling mani-pulation. The microcirculatory blood perfusion units （MBPU） was captured and compared between groups of participants using laser speckle contrast imaging （LSCI） for 5 mins in each of the four stages， state before acupuncture （R1）， after needle insertion （A1）， after needle twirling （A2） and after needle withdrawal （R2）. The participants' feelings such as relaxation， concentration， drowsiness， energy flow at acupoints were compared between groups， and the adverse reactions were recorded. ResultsThe MBPU values of R1， A1， A2 and R2 stages in mentality-controlling acupuncture group were 67.92±18.40 PU， 168.13±46.03 PU， 144.19±44.40 PU， 159.73±65.21 PU， respectively. The simple acupuncture group were 79.85 （66.80， 99.40）PU， 193.31 （173.15， 224.80）PU， 147.68 （128.12， 198.30）PU， 158.09 （126.05， 207.59）PU respectively. There was a statistically significant difference in MBPU between groups of the four stages （P＜0.01）. Among them， the MBPU in the A1 stage of both groups was significantly larger than that in the R1 stage， the MBPU in the A2 stage significantly smaller than that in the A1 stage， and the MBPU in the R2 stage was significantly larger than that in the R1 stage （P＜0.01）. MBPU in the R2 stage of the mentality-controlling acupuncture group was larger than that in the A2 stage （P＜0.05）. The difference of MBPU between A2 and A1 in mentality-controlling acupuncture group was significantly smaller than that in the simple acupuncture group， and the difference was statistically significant （t = 3.79， P＜0.01）. In mentality-controlling acupuncture group， 18 participants felt relaxed （90%）， 15 concentrated （75%）， 3 felt sleepy （15%）， and 14 felt energy flow at acupoints （70%）； while in the simple acupuncture group， 13 participants felt relaxed and sleepy （65%）， 6 concentrated and 6 felt energy flow at acupoints （30%）. The number of participants with concentration and energy flow at acupoints in mentality-controlling acupuncture group was higher than that in the simple acupuncture group， and the number felt sleepy was lower than that in the simple acupuncture group （P＜0.05）. No needle fainting， needle site infection， local haematoma and any other adverse reactions were found in both groups. ConclusionAcupuncture could affect the changes of local microcirculation， and controlling mentality during acupuncture can slow the rate of MBPU reduction and enhance the post-acupuncture effect with a favourable safety profile.

To investigate the recent prevalence and molecular epidemiological characteristics of por-cine diarrhea viruses in Sichuan Province,this study used fluorescence quantitative PCR to detect porcine diarrhea samples from multiple regions in Sichuan Province from 2021 to 2023.RT-PCR was used to identify the genotypes of PEDV,PoRVA,PDCoV,and PTV,and their genetic variabil-ity,evolutionary characteristics,and recombination events were analyzed.The results showed that PEDV,PoRVA,PDCoV,and PTV were still prevalent in Sichuan region,with overall positive rates of 14.2％(40/281),13.2％(37/281),15.6％(44/281),and 12.5％(35/281),respectively.PEDV mixed infection with other pathogens was the most common.This study obtained a total of six strains of G2b PEDV,three strains of G3 PDCoV,three strains of G9P[13]PoRVA,one strain of G3P[13]PoRVA,three strains of Type 5 PTV,and one strain of Type 9 PTV.Compared to the seven vaccine strains including CV777,DR13,KPEDV-9,Chinju99,KNU-0801,AJ1102,and LW/L,the 6 PEDV strains showed multiple amino acid mutation sites in the COE region and S1D epitope region.Among them,the strains PSCLZ01 and PSCMY04 formed a separate branch in the phylogenetic tree.The three PDCoV strains have a closer genetic evolution distance to the previ-ously prevalent strains in Sichuan,but they also have 6-48 amino acid mutations compared to them.The four PoRVA strains have 104-108 amino acid variations in the VP4 gene compared to the early vaccine strain LLR,and they have 25 common amino acid variations in the VP7 gene.From the phylogenetic tree,the VP7 gene of RSCMY01/G3P[13]belongs to the same branch as the Heilongjiang strain LNCY,but its VP4 gene clusters with the Sichuan strain SCYA-C7,indica-ting that this PoRVA strain may have undergone genetic reassortment during inter-provincial transmission between different genotypes.It is worth noting that in the detected samples of PTV-5 and PTV-9,other diarrheal viruses tested negative,indicating that these two genotypes of PTV may be important pathogens causing porcine diarrhea.Additionally,the S gene of PEDV PSCLZ01 strain and PDCoV PCSCMY02 strain have undergone recombination events,and their parental strains come from different regions,both domestic and international.These findings reveal the main types of porcine diarrheal viruses,as well as their genetic diversity and variations in Sichuan Province in recent years.This study enriches the molecular epidemiological data of porcine diarrhe-al pathogens in the region and provides an important theoretical basis for the prevention,control,and purification of porcine diarrhea in the local area.

Objective To develop deep learning-based auxiliary diagnostic models for diverse pulmonary diffuse cystic diseases,and subsequently evaluate their classification performance to identify the optimal model for clinical diagnosis.Methods A total of 288 patients diagnosed with idiopathic pulmonary fibrosis(IPF),pulmonary lymphangioleiomyomatosis(PLAM),and pulmonary Langerhans cell histiocytosis(PLCH)were prospectively enrolled from the First Affiliated Hospital of Guangzhou Medical University between January 2010 and October 2022,comprising 76 cases of IPF,179 cases of PLAM,and 33 cases of PLCH.A total of 877 CT cases were collected,comprising 232 cases of IPF,557 cases of PLAM,and 88 cases of pulmonary PLCH.Based on the cutoff date of December 31,2019,the CT scans were divided into two datasets:dataset A consisted of 500 CT scans including 185 IPF cases,265 PLAM cases,and 50 PLCH cases;while dataset B comprised 377 CT scans with a distribution of 47 IPFcases,292 PLAMcases,and 38 PLCH cases.The Dataset A was randomly partitioned into training set,validation set,and test set in a ratio of 7∶1∶2.Subsequently,six distinct deep learning neural networks were employed for training after preprocessing and data augmentation.Receiver operating characteristic curves were generated to assess the model performance using metrics such as area under the curve(AUC),accuracy,sensitivity,specificity,and F1 score in order to identify the optimal model.Furthermore,a test set B comprising 30 randomly selected cases from dataset B for each disease type was utilized to evaluate the trained optimal model by employing the same aforementioned metrics.Results In test A,six well-established diagnostic models demonstrated superior classification performance for IPF and LAM,with an AUC greater than 0.9.For LCH,EfficientNet exhibited low classification efficiency with an AUC between 0.6 and 0.7,while Vgg11 showed an AUC between 0.8 and 0.9;the other four models displayed excellent classification efficiency with an AUC greater than 0.9.Except for Inception V3,the remaining five diagnostic models performed poorly in identifying and classifying LCH lesions.Considering multiple indicators,the InceptionV3 model showcased optimal comprehensive performance among the six models,achieving high evaluation parameters such as overall accuracy(94.90%),precision(93.49%),recall(90.84%),and specificity(96.91%).TestB was conducted using the trained InceptionV3 model resulting in an accuracy of 81%,precision of 82%,recall of 81%,and specificity of 90%.Conclusions Six recognition and classification models,developed using deep learning technology in conjunction with pulmonary CT images,demonstrate effective discrimination between LAM,LCH,and IPF.Notably,the model constructed utilizing the InceptionV3 neural network exhibits superior efficiency in accurately recognizing and classifying IPF and LAM.

Objective:To investigate the efficacy of color Doppler ultrasound-guided percutaneous nephrostomy in the treatment of anastomotic leakage after laparoscopic pyeloplasty.Methods:A retrospective analysis was performed for the data of 15 children with peritoneal irritation after LP who were admitted to the First Affiliated Hospital of Zhengzhou University from January 2018 to January 2023, of which 10 cases were anastomotic leaks and 5 cases were with renal pelvic blood clots. There were 12 males and 3 females. Age (4.2±2.7) years. The lesions were located on the left side of 11 cases and on the right side of 4 cases. All 15 cases had varying degrees of nausea, vomiting, abdominal pain and other symptoms. Physical examination: the children all showed painful faces and tense abdominal muscles. 15 patients had a preoperative pain score of 9.5 (8, 10). Ultrasound examination showed that the anterior and posterior diameters of renal pelvis separation were (34.93±4.86) mm, the anterior and posterior diameter/renal parenchymal thickness of renal pelvis separation was 15.66±1.02, renal dynamic nuclear imaging shows the renal function of the affected side was (29.69±1.71)%. Thirteen cases had the above symptoms before the abdominal drainage tube was removed, and the time of symptom onset was (3.3±1.1) days after surgery, of which 8 cases had a large increase in abdominal drainage, and color Doppler ultrasonography showed a large amount of fluid in the intra-abdominal intestinal space (about 500 ml). In 5 cases, the intraperitoneal drainage volume did not increase, and color Doppler ultrasonography showed strong echo in the renal pelvis, and blood clots were considered. All 13 patients were placed in the prone position under local anesthesia and underwent color Doppler ultrasound-guided percutaneous nephrostomy. The remaining 2 cases had abdominal drainage tube removed on the 3rd day after surgery, and peritoneal irritation signs appeared on the 4th and 6th days after surgery, respectively. Color Doppler ultrasonography showed that there was a large amount of fluid in the intra-abdominal intestinal space, and color Doppler ultrasound-guided peritoneal puncture and drainage + prone percutaneous nephrostomy was performed in the supine position under local anesthesia, and the biochemical analysis of the peritoneal puncture drainage fluid was confirmed to be anastomotic urine leakage. The drainage volume and urine output of 15 cases of peritoneal puncture drainage and pyelostomy were recorded, and the relief of nausea and vomiting symptoms and the score of postoperative pain after percutaneous nephrostomy were recorded. The changes of hydronephrosis and renal function before and after percutaneous nephrostomy were compared.Results:In this study, 15 patients underwent percutaneous nephrostomy with a duration of (16.8±1.9) min. The symptoms of nausea and vomiting disappeared after operation, and the pain scores were 3.2(2, 4) and 0.4(0, 2) at 2 h and 12 h after operation, respectively, which were statistically significant compared with those before operation ( P<0.01). In 13 children with simple percutaneous nephrostomy, the abdominal drainage tube was removed on (3.6±0.8) days and (8.6±1.0) days after percutaneous nephrostomy. In 2 children with peritoneal puncture and drainage plus percutaneous nephrostomy, the abdominal drainage tube was removed 3 days after the fistula operation, and the pyelostomy tube was removed 8 days after the fistula operation. The anterior and posterior diameters of renal pelvis separation were (10.87±4.05), (10.13±3.50) and (9.13±3.11) mm by color Doppler ultrasound at 3, 6 and 12 months after LP operation, respectively, and there were statistically significant differences compared with preoperative comparisons ( P<0.01).The diameter before and after renal pelvis separation was (7.60±2.86) mm, the diameter before and after renal pelvic separation/renal parenchymal thickness was 1.97±0.22, and the renal function was (39.23±2.66)% at 24 months after operation, which was statistically significant compared with that before operation ( P<0.01). Conclusions:Color Doppler ultrasound-guided percutaneous nephrostomy can effectively alleviate symptoms in the early stage, which could help to the healing of ureteral anastomosis, and has less trauma and short operation course.

Objective and MethodChemical components in four varieties of Moringa Folium （MF）； traditional Indian YD， modified species of Indian species PKM1， modified species of PKM1 species PKM2， and red river No.1 variety HH） were qualitatively analyzed by ultra-high performance liquid chromatography quadrupole time of flight mass spectrometry（UPLC-Q-TOF-MS） and gas chromatography mass spectrometry（GC-MS）， and potential mechanism and material basis of MF in the treatment of constipation were revealed based on network pharmacology. ResultData of accurate relative molecular mass and fragment ions in primary and secondary mass spectra in both positive and negative ion modes were acquired by UPLC-Q-TOF-MS， and then 20 nonvolatile components were identified from the four varieties by comparison with references and consulting literature reports. Nineteen volatile components were identified by comparing mass spectrometry information and that in NIST （version 1.7） based on GC-MS， and 674 chemical component targets were predicted using SwissTargetPrediction and SEA after integration and duplicate elimination. A total of 1 086 constipation-related targets were predicted using GeneCards. With Venny， 88 intersection targets were obtained by mapping chemical component targets and disease targets and venny diagram was drawn. STRING and Cytoscape were used to plot protein-protein interaction（PPI） network diagram. Gene ontology（GO） function analysis and Kyoto encyclopedia of genes and genomes（KEGG） pathway analysis were completed through Metascape， which indicated that MF treated constipation mainly via thyroid hormone signaling pathway， advanced glycation end products/receptor for advanced glycation end products（AGE/RAGE） signaling pathway， and cancer signaling pathway. Additionally， the "component-target-pathway" map was plotted by Cytoscape， which predicted that the key components of MF in the treatment of constipation were adenosine， astragalin， geranylacetone， 2-methyloctan-3-one， palmitic acid and oleamide. Also， we inferred that the core targets might be prostaglandin-endoperoxide synthase 2（PTGS2）， tumor necrosis factor（TNF）， mitogen-activated protein kinase 1（MAPK1）， alpha 2A adrenergic receptor（ADRA2A）， and interleukin （IL）-6， which distributed in multiple tissues such as colon， small intestine， and rectum. ConclusionThis study clarified the volatile and non-volatile divisions in four varieties of MF comprehensively， and explained that MF treated constipation by reducing inflammatory state and promoting intestinal movement and secretion of intestinal fluid， which provided reference for further quality evaluation and clinical research of MF.
