In this article, the Chinese Traditional Medicine and Materia Medica Subject Headings, Standards of the People's Republic of China - Classification and Codes of Diseases and Zheng of Traditional Chinese Medicine and the Chinese Terms in Traditional Chinese Medicine and Pharmacy were compared. Three standards were compared from the terminology quantity, content and classification. Each standard has its special feature. The compatibility and consistency are not strong in these standards. More authoritative traditional Chinese medicine terminology standards need to be established for the application in the clinical practice and scientific research.

Objective To summarize the efficacy and the feasibility of 125I seed implantation for recurrence cervical lymph node of head and neck tumor after radiotherapy or radiotherapy plus neck dissection. Methods Thirty-six patients with the recurrence cervical lymphnode of head and neck tumor after radiotherapy (17 patients) or radiotherapy plus neck dissection (19 patients) were treated with 125I seed implantation guided by ultrasound or CT under local anesthesia. The median number of seeds was 27( range from 3 to 78 ). Postoperative quality evaluation were routinely obtained for all patients. The actuarial D90 ranged from 90-160 Gy (median, 130 Gy). Results The follow-up rate was 100%. The number of the patients who were followed up over 1-and 2-year were 11 and 3. The overall response rate was 81%. The 1-and 2-year over local control rates, over survival rates were 69% and 35%, 50% and 22%, respectively.The 1-and 2-year local control rates in patients with recurrence node after radiotherapy plus neck dissection were 72% and 54%, while those were 67% and 50% in patients with recurrence node after radiotherapy,respectively (χ2=00,P=0.965). The 1-and 2-year survival rates in two groups were 48%, 13% , and 51%, 39%, respectively (χ2=0.17, P=0.676). Conclusions 125I seed implantation is a safe,minimal invasive with low morbidity and high efficacy salvage treatment method for cervical lymph node recurrence of head and neck tumor after radiotherapy with or without neck dissection.

Aim To research dynamically the changes of endogenous cystathionine- β-synthase/hydrogen sul-fide system in PC12 cells injury induced by rotenone. Methods Rotenone-induced injury in PC12 cells ( characteristic of dopaminergic neurons) was used as a PD cell model. The expression of CBS was evaluated by Western blot. Intracellular CBS activity and H2 S production were detected by Methylene blue spectro-phot-ometric method. The viability of PC12 cells was measured by CCK-8 assay. GSH detection kit was used to detect the intracellular GSH content. Results In the groups of 6 and 12 hours, the expression and activ-ity of CBS were elevated, and the production of H2 S was increased. In the groups of 24 and 48 hours, CBS expression and activity were significantly decreased, and the amount of H2 S was significantly reduced. Ap-plication of 1. 5 μmol·L-1 rotenone for different time (6-48h) could decrease the cell viability and intra-cellular GSH contents in a time-dependent manner. Conclusions The expression and activity of endoge-nous CBS, stimulated by rotenone, are elevated firstly and then decreased. The generation of H2 S, stimulated by rotenone, is increased and then reduced significant-ly, which may be related to PC12 cells against oxida-tive stress damage induced by rotenone.

Objective:To study the diagnostic value of non-enhanced lesions on enhanced CT in lung consolidation for necrotizing pneumonia in children.Methods:A total of 101 cases of necrotizing pneumonia with air sacs on CT scan who were hospitalized in the Department of Respiratory Intervention, Qilu Children′s Hospital of Shandong University from August 2016 to September 2018 were enrolled in this study(group with air lucency). Besides, another 75 cases of lobar pneumonia with non-enhanced lesions in lung consolidation but without air sacs on enhanced CT were also included from the same hospital over the same period(group without air lucency). Clinical data of these patients were retrospectively collected and statistically analyzed.Results:The white blood cell count was (12.5±5.5)×10 9/L in group with air sacs and (10.8±4.1)×10 9/L in group without air sacs, and the difference was statistically significant( t=-2.161, P=0.032). There was no statistical difference between the group with and without air sacs in age, gender distribution, the course prior to admission, duration of fever after admission, length of hospital stay, medical expense, the neutrophils percentage in peripheral blood, C-reactive protein, the erythrocyte sedimentation rate, serum procalcitonin, serum D-Dimer, serum lactate dehydrogenase, serum albumin, bronchoscopy times, the bronchial mucosal erosion ratio, the mucus plug score, the lavage purulent lavage ratio, and the ratio of luminal stricture or atresia in late bronchoscopy(all P>0.05). Conclusions:The clinical course of patients with non-enhanced lesions in lung consolidation but without air sacs is almost identical to that of patients with air sacs on CT scan.The presence of non-enhanced lesions in lung consolidation can be used as diagnostic basis of necrotizing pneumonia in children.

Objective:To explore the case characteristics, treatment and prevention measures of cardiac thrombus in children caused by Mycoplasma pneumoniae infection, so as to improve the clinicians′ understanding of the disease.Methods:The clinical data of 10 children with cardiac thrombus caused by Mycoplasma pneumoniae infection treated in Department of Respiratory Intervention, Jinan Children′s Hospital from November 2015 to January 2020 were retrospectively analyzed, including datum of cases, laboratory results, imaging data and follow-up results.Results:A total of 10 children (7 males and 3 females) were included with the median age of 6.5 years old, and all had fever for more than 1 week.The plasma D-dimer (D-D) of 9 children was significantly increased, and the C-reactive protein (CRP) of 6 children was increased.After anti-infection treatment, the absorption of pneumonia with atelectasis was better than before.The embolus disappeared after operation in 1 case, and the remaining 9 cases received anticoagulant therapy, among which 7 cases received Heparin anticoagulant therapy alone: cardiac embolus disappeared during hospitalization in 2 cases, disappeared after 2 weeks of oral administration of Dipyridamole outside the hospital in 1 case, and the other 4 cases received Heparin anticoagulant therapy alone during hospitalization with poor effect, embolus disappeared in 2 cases 4 and 5 months after discharge respectively, and 2 cases were not reexamined due to personal reasons; the embolus disappeared 2 months after discharge in 2 cases who were changed to low-molecular weight Heparin + Warfarin anticoagulant therapy after failing to respond to Heparin anticoagulant therapy.All the 10 cases showed no symptoms of tachypnea or chest pain during telephone follow-up.Conclusions:Children with long fever time and significantly elevated CRP and D-D are more likely to form thrombus.Anticoagulant therapy is effective after thrombosis, and surgical thrombectomy can be performed in children who have failed to respond to anticoagulant therapy or worry about complications caused by dropped embolus.

With the rapid development of an aging society, the number of Total Hip and Knee Arthroplasty continues to increase, which makes the country medical insurance funds and elderly patients burden with medical treatment increasing. The early ambulation of postoperative patients with Total Hip and Knee Arthroplasty can effectively shorten the length of hospital stay, save hospitalization costs, and improve joint function. Therefore, this article reviews the concept, status, implementation obstacles, promotion measures and other aspects of early ambulation of postoperative patients undergoing Total Hip and Knee Arthroplasty, with a view to provide theoretical reference for the development of standar-dized and efficient early ambulation of medical personnel.

OBJECTIVETo study the clinical efficiency, electroencephalogram (EEG) changes and cognitive improvements of ketogenic diet (KD) in children with refractory epilepsy.

METHODSTwenty pediatric patients (7-61 months in age) with refractory epilepsy were recruited between August 2012 and August 2013. KD therapy was performed on all participants for at least 3 months based on a fasting initiation protocol with the lipid-to-nonlipid ratio being gradually increased to 4 : 1. Seizure frequency, type and degree were recorded before and during KD therapy. A 24 hours video-electroencephalogram (V-EEG) examination and Gesell Developmental Scale assessment were performed prior to KD therapy, and 3, 6, 9 months after KD therapy.

RESULTSSix patients became seizure free after KD therapy, with a complete control rate of 30%. Seizure frequency reduction occurred in 13 (65%) patients, EEG improvement in 8 (40%) patients, and improvement in Gesell Developmental Scales (gross motor and adaptability in particular) in 6 (30%) patients. The KD therapy-related side effects were mild.

CONCLUSIONSKD therapy is safety and effective in reducing seizure frequency and improving EEG and cognitive function in children with refractory epilepsy.

Objective:To develop a visualized nomogram with a predictive value to differentiate mass-forming chronic pancreatitis (MFCP) from pancreatic ductal adenocarcinoma (PDAC) patients with chronic pancreatitis (CP) history.Methods:The clinical and radiological data of 5 433 CP patients acoording to the Asia-Pacific Diagnostic Criteria between February 2011 and February 2021 in the First Affiliated Hospital of Naval Medical University were retrospectively analyzed, and 71 PDAC patients with CP history and 67 MFCP who underwent surgery or biopsy and pathologically confirmed were eventually enrolled. The training set included 44 patients with MFCP and 59 patients with PDAC who were diagnosed between February 2011 and April 2018. The validation set consisted of 23 patients with MFCP and 12 patients with PDAC who were diagnosed between May 2018 and February 2021. Univariate and multivariate logistic regression analyses were performed to develop a prediction model for PDAC and MFCP, and the model was visualized as a nomogram. ROC was used to evaluate the predictive efficacy of the nomogram, and the clinical usefulness was judged by decision curve analysis.Results:The univariate analysis showed that a significant association with pancreatic cancer were observed for the duct-to-parenchyma ratio ≥0.34, pancreatic duct cut-off, pancreatic portal hypertension, arterial CT attenuation, portal venous CT attenuation, delayed CT attenuation, and vascular invasion in both the training and validation cohorts, but the duct-penetrating sign in the training cohort only. The multivariable logistic regression analysis showed that statistically significant differences (all P value <0.05) existed in cystic degeneration, a duct-to-parenchyma ratio ≥0.34, the duct-penetrating sign, pancreatic portal hypertension and arterial CT attenuation between the two cohorts. The above parameters were selected for the logistic regression model. The predicted model=3.65-2.59×cystic degeneration+ 1.26×duct-to-parenchyma ratio≥0.34-1.40×duct-penetrating sign+ 1.36×pancreatic portal hypertension-0.05×arterial CT attenuation. Area under the curve, sensitivity, specificity and accuracy of the model-based nomogram were 0.87 (95 CI 0.80-0.94), 89.0%, 75.0% and 83.5% in the training cohort, and 0.94 (95 CI 0.82-0.99), 91.7%, 100% and 97.1% in the validation cohort, respectively. Decision curve analysis showed that when the nomogram differentiated MFCP from PDAC patients with CP history at a rate of 0.05-0.85, the application of the nomogram could benefit the patients. Conclusions:The nomogram based on CT radiological features accurately differentiated MFCP from PDAC patients with CP history and provide reference for guiding the treatment and judging the prognosis.

Objective:To investigate the relationship between the perineural invasion score based on multidetector computed tomography (MDCT) and extrapancreatic perineural invasion (EPNI) in pancreatic ductal adenocarcinoma (PDAC).Methods:The clinical, radiological, and pathological data of 374 patients pathologically diagnosed as pancreatic cancer who underwent radical resection in the First Affiliated Hospital of Naval Medical University from March 2018 to May 2020 were analyzed retrospectively. Patients were divided into EPNI negative group ( n=111) and EPNI positive group (n=263) based on the pathological presence of EPNI. The perineural invasion score was performed for each patient based on radiological images. Univariate and multivariate logistic regression models were used to analyze the association between the perineural invasion score based on MDCT and EPNI in PDAC. Results:There were significant statistical differences between EPNI negative group and positive group on both pathological characteristics (T stage, N stage, invasion of common bile duct, and positive surgical margin) and radiological characteristics (tumor size, vascular invasion, lymph node metastasis, perineural invasion score based on MDCT, pancreatic border, parenchymal atrophy, invasion of duodenum, invasion of spleen and splenic vein and invasion of common bile duct) (all P value <0.05). Univariate analysis revealed that the tumor size, vascular invasion, lymph node metastasis, perineural invasion score based on MDCT, pancreatic border, pancreatic atrophy, invasion of duodenum, invasion of spleen and splenic vein and invasion of common bile duct were independently associated with EPNI. Multivariate analyses revealed that the perineural invasion based on MDCT was an independent risk factor for EPNI in pancreatic cancer (score=1, OR=2.93, 95% CI 1.61-5.32, P<0.001; score=2, OR=5.92, 95% CI 2.68-13.10, P<0.001). Conclusions:The perineural invasion score based on MDCT was an independent risk factor for EPNI in pancreatic cancer and can be used as an evaluation indicator for preoperative prediction of EPNI in PDAC.

Objective:To explore the differential diagnosis of pancreatic acinar cell carcinoma (PACC) and pancreatic ductal adenocarcinoma (PDAC) based on multidetector computed tomography (MDCT) features.Methods:The clinical, pathological and MDCT imaging data of 26 patients with pathologically confirmed PACC and 145 patients with pathologically confirmed PDAC who underwent MDCT from November 2013 to April 2021 were retrospectively studied. The differences of MDCT features including tumor location, tumor size, common pancreatic duct and bile duct dilatation, pancreatitis, lymph node metastasis, cyst, pancreatic parenchyma atrophy, duodenal involvement, bile ductal and vascular involvement between the two groups were compared. Univariate analysis and multivariate analysis by logistic regression models were performed to identify the independent predictive factors for PACC.Results:The tumor size, bile duct dilatation, lymph node metastasis, pancreatic parenchyma atrophy and vascular involvement were significantly different between PACC group and PDAC group (all P value<0.05). Multivariate analysis revealed that the tumor size ( OR=1.07, 95% CI 1.028-1.15, P=0.001), lymph node metastasis ( OR=0.23, 95% CI 0.065-0.800, P=0.02), pancreatic parenchyma atrophy ( OR=0.15, 95% CI 0.048-0.490, P=0.002) were closely associated with PACC. Conclusions:The tumor size, bile duct dilatation, lymph node metastasis, pancreatic parenchyma atrophy and vascular involvement evaluated by MDCT had a certain value in differentiating PACC from PDAC, and the tumor size, lymph node metastasis and pancreatic parenchyma atrophy were independent predictors for the diagnosis of PACC.
