ObjectiveMicrotube associated protein-2 （MAP-2）， alpha-tubulin （α-tubulin）， and synaptophysin （SYP） are important proteins in neuronal signal communication. This paper observed the effects of modified Zhigancao Tang on the expression of serum α-Synuclein （α-Syn） and its oligomers， MAP-2， α-tubulin， and SYP of patients with liver and kidney deficiency of Parkinson's disease （PD）， analyzed their correlation， and evaluated the therapeutic effect of modified Zhigancao Tang in patients with liver and kidney deficiency of PD based on α-Syn transmission pathway mediated by neuronal communication in vivo. MethodsA total of 60 patients with PD who met the inclusion criteria were randomly divided into a treatment group （30 cases） and a control group （30 cases）. Both groups were treated on the basis of PD medicine， and the treatment group was treated with modified Zhigancao Tang. Both groups were treated for 12 weeks. The changes in UPDRS score， TCM syndrome score， and expression of serum α-Syn and its oligomers， MAP-2， α-tubulin， and SYP were observed before and after 12 weeks of treatment in each group. The correlation between the above-mentioned serum biological indexes and the levels of serum α-Syn and its oligomers was analyzed. ResultsAfter treatment， the TCM syndrome score， UPDRS score， UPDRS-Ⅱ score， and UPDRS-Ⅲ score of the treatment group were significantly decreased （P<0.05， P<0.01）. The UPDRS score， UPDRS-Ⅱ score， and UPDRS-Ⅲ scores in the treatment group were significantly decreased compared with those in the control group after treatment （P<0.05）. After treatment， the total effective rate of the control group was 63.3% （19/30）， and that of the treatment group was 86.7% （26/30）. The clinical effect of the observation group was better than the control group （Z=-2.03， P<0.05）. The total effective rate of the observation group was better than that of the control group， and the difference was statistically significant （χ²=5.136， P<0.05）. After treatment， the oligomer level of serum α-Syn and MAP-2 level in the treatment group were significantly decreased （P<0.05， P<0.01）. The levels of serum α-Syn and its oligomers， as well as α-tubulin in the treatment group， were significantly decreased compared with those in the control group after treatment （P<0.05， P<0.01）. Serum α-Syn was correlated with serum MAP-2 and α-Syn oligomer in patients with PD （P<0.05， P<0.01） but not correlated with serum SYP . Serum α-Syn oligomers of patients with PD were correlated with serum MAP-2 and α-tubulin （P<0.05， P<0.01） but not correlated with serum SYP level. Serum SYP of patients with PD was correlated with serum MAP-2 （P<0.05）. ConclusionModified Zhigancao Tang has a therapeutic effect on patients with liver and kidney deficiency of PD by inhibiting the production of α-Syn oligomers and intervening α-Syn microtubule transport pathway in vivo.

The detection rate of multifocal / multicentric breast cancer (MMBC) is increasing, and the local treatment of MMBC is attracting more attention. Relevant research focuses on the selection of surgical methods, the application of radiotherapy, and the feasibility of local ablation. Currently, due to the high rate of local recurrence in breast conserving surgery, most Chinese doctors recommend mastectomy to patients with MMBC. Recent studies have shown that with the development of imaging technology, surgical techniques, accurate judgment of the resection margin, the emergence of new therapeutic drugs and the improvement of the accuracy of radiotherapy, for eligible patients with MMBC, breast conserving surgery did not increase the local recurrence rate while ensuring negative margin and cosmetic results. Whether patients with MMBC must receive adjuvant radiotherapy after mastectomy is controversial, with some evidence suggesting that MMBC may increase the risk of local recurrence and should be an important consideration for radiotherapy, and there is also evidence that the local recurrence rate of MMBC was higher regardless of the type of surgery. In general, the local treatment modality for MMBC is essentially the same as that for unifocal breast cancer, but more prospective studies are needed for further evaluation.

Objective:To investigate the correlation between systemic immune inflammatory index (SII) and other metabolic indicators and diabetic epiretinal membranes (dERM).Methods:A retrospective case-control study. From March 2022 to July 2023, 81 patients (81 eyes) with dERM in Department of Ophthalmology, Affiliated Jinhua Hospital of Zhejiang University of Medicine School diagnosed by fundus screening were included in the study. A total of 81 patients (81 eyes) with diabetes who were matched in age, gender, and duration of diabetes and had no dERM or diabetic macular edema in both eyes during fundus screening were selected as the control group. All patients underwent optical coherence tomography (OCT) examination and laboratory tests for peripheral blood neutrophil, lymphocyte, platelet counts, serum albumin, blood lipids, uric acid, and glycosylated hemoglobin (HbA1c). SII was calculated. Random urine samples were collected for urinary albumin/creatinine ratio (ACR) testing. The OCT device's own analysis software obtained the macular volume coefficient, including central foveal thickness (CMT), macular volume, and average macular thickness. The macular volume coefficient, SII, serum albumin, blood lipids, uric acid, HbA1c, and ACR between the two groups were compared using paired t tests or Mann-Whitney U tests. Conditional logistic regression analysis was performed to evaluate the risk factors for dERM; Spearman correlation test was used to analyze the correlation between CMT, SII, ACR, disorganization of retinal inner layers (DRIL), intraretinal cyst (IRC), and hyper-reflective foci (HRF) in patients with dERM. Results:There were significant differences in CMT, macular volume, average macular thickness, SII, serum albumin, and ACR between the dERM group and the control group ( Z=-7.234, -6.306, -6.400, -3.063, -2.631, -3.868; P<0.05). Conditional logistics regression analysis showed that high SII [odds ratio (OR)= 3.919, 95% confidence interval ( CI) 1.591-9.654, P=0.003] and ACR ( OR=4.432, 95% CI 1.885-10.420, P=0.001) were risk factors for dERM. Spearman correlation analysis showed that HRF, IRC, DRIL were positively correlated with CMT ( Rs=0.234, 0.330, 0.248; P=0.036, 0.003, 0.026); HRF was positively correlated with SII and ACR ( Rs=0.233, 0.278; P=0.036, 0.012). Conclusion:Elevated SII and ACR are independent risk factors for the occurrence of dERM.

Objective To construct and validate of a nomogram predictive model for high-volume lymph node metastasis(HVM)in multifocal papillary thyroid carcinoma(MPTC).Methods Between January 2010 to January 2024,a total of 1146 and 234 patients with multifocal papillary thyroid carcinoma(MPTC)were diagnosed at Hangzhou First People's Hospital(Center A)and Hangzhou Cancer Hospital(Center B),respectively.Patients from Center A were randomly allocated to training set(n=803)and testing set(n=343)in a 7:3 ratio,while those from Center B(n=234)comprised an external validation set.Independent risk factors for HVM in MPTC patients were identified through univariate and multivariate Logistic regression analysis in training set,leading to the development of a nomogram predictive model.The generalizability of this model was subsequently assessed using both testing set and external validation set.The area under the curve(AUC)of receiver operating characteristic curve,sensitivity,and specificity evaluate the discriminative ability of the model.Results The incidence of HVM was 13.3％at center A and 12.8％at center B.Logistic regression identified male gender(OR=2.91,95％CI:1.835-4.599),maximum lesion diameter(OR=1.05,95％CI:1.021-1.070),and age(OR=0.95,95％CI:0.936-0.972)as independent risk factors for HVM.Anomogram based on these factors showed an AUC of 0.767 with 72.6％sensitivity and 70.2％specificity in training set,and 0.838 with 94.9％sensitivity and 68.4％specificity in testing set,and 0.769 with 63.3％sensitivity and 84.3％specificity in external validation set.The calibration curve demonstrated good agreement with the ideal curve.Conclusion The prediction model constructed based on clinical risk factors can effectively predict the probability of HVM in MPTC patients.

Objective:To investigate the safety and dose of 4D template (real-time adjustable angle template) in the treatment of advanced malignant tumors with 125I seeds. Methods:98 patients with advanced malignant tumors admitted to Department of Thoracic Surgery of Shaanxi Provincial Tumor Hospital were treated with 4D template-navigated radioactive 125I seed implantation from June 2018 to December 2019. Preoperative TPS plan, intraoperative optimization, postoperative verification of immediate dose and postoperative evaluation of implantation dose were performed. The treatment results were observed. Results:All 98 patients completed the seed implantation. The implantation dose of GTV of implantation site receiving external irradiation was (12 489±414) cGy and the dose of no external irradiation was (15 036±514) cGy. V 100% was 84.7%-94.1%, and 88.2%-93.7%. The implantation dose of CTV was (7 450±621) cGy, and (9 080±761) cGy. The quality of dose implantation was evaluated as: excellent in 89 cases (91%, 89/98), good in 7 cases (7%, 7/98), fair in 2 cases (2%, 2/98), and poor in 0 case, respectively. The symptom relief rate of patients with pain was 92%(36/39). The 1-and 2-year local control rates were 61%, 36% and 82%, 54% in patients treated with and without external irradiation, respectively. The difference was statistically significant ( P=0.02). The incidence rates of pneumothorax and hemoptysis were 19%(9/48) and 10%(5/48). No corresponding complications were observed in other parts of the patients. Conclusion:4D template-assisted 125I seed therapy is safe and effective for malignant tumors, and intraoperative adjustment of needle angle and dose optimization can realize the precise control of implantation dose.

Objective:To compare and analyze the clinical features of patients with severe coronavirus disease 2019 (sCOVID-19) and severe community acquired pneumonia (sCAP) who meet the diagnostic criteria for severe pneumonia of the Infectious Diseases Society of America/American Thoracic Society (IDSA/ATS).Methods:A retrospective comparative analysis of the clinical records of 116 patients with sCOVID-19 admitted to the department of critical care medicine of Wuhan Third Hospital from January 1, 2020 to March 31, 2020 and 135 patients with sCAP admitted to the department of critical care medicine of Shanghai First People's Hospital from January 1, 2010 to December 31, 2017 was conducted. The basic information, diagnosis and comorbidities, laboratory data, etiology and imaging results, treatment, prognosis and outcome of the patients were collected. The differences in clinical data between sCOVID-19 and sCAP patients were compared, and the risk factors of death were analyzed.Results:The 28-day mortality of sCOVID-19 and sCAP patients were 50.9% (59/116) and 37.0% (50/135), respectively. The proportion of arterial partial pressure of oxygen/fraction of inspired oxygen (PaO 2/FiO 2)≤250 mmHg (1 mmHg ≈ 0.133 kPa) in sCOVID-19 patients was significantly higher than that of sCAP [62.1% (72/116) vs. 34.8% (47/135), P < 0.01]. The possible reason was that the proportion of multiple lung lobe infiltration in sCOVID-19 was significantly higher than that caused by sCAP [94.0% (109/116) vs. 40.0% (54/135), P < 0.01], but the proportion of sCOVID-19 patients requiring mechanical ventilation was significantly lower than that of sCAP [45.7% (53/116) vs. 60.0% (81/135), P < 0.05]. Further analysis of clinical indicators related to patient death found that for sCOVID-19 patients PaO 2/FiO 2, white blood cell count (WBC), neutrophils (NEU), neutrophil percentage (NEU%), neutrophil/lymphocyte ratio (NLR), total bilirubin (TBil), blood urea nitrogen (BUN), albumin (ALB), Ca 2+, prothrombin time (PT), D-dimer, C-reactive protein (CRP) and other indicators were significantly different between the death group and the survival group, in addition, the proportion of receiving mechanical ventilation, gamma globulin, steroid hormones and fluid resuscitation in death group were higher than survival group. Logistic regression analysis showed that the need for mechanical ventilation, NLR > 10, TBil > 10 μmol/L, lactate dehydrogenase (LDH) > 250 U/L were risk factors for death at 28 days. For sCAP patients, there were significant differences in age, BUN, ALB, blood glucose (GLU), Ca 2+ and D-dimer between the death group and the survival group, but there was no significant difference in treatment. Logistic regression analysis showed that BUN > 7.14 mmol/L and ALB < 30 g/L were risk factors for 28-day death of sCAP patients. Conclusions:The sCOVID-19 patients in this cohort have worse oxygen condition and symptoms than sCAP patients, which may be due to the high proportion of lesions involving the lungs. The indicators of the difference between the death group and the survival group were similar in sCOVID-19 and sCAP patients. It is suggested that the two diseases have similar effects on renal function, nutritional status and coagulation function. But there were still differences in risk factors affecting survival. It may be that sCOVID-19 has a greater impact on lung oxygenation function, inflammatory cascade response, and liver function, while sCAP has a greater impact on renal function and nutritional status.

Objective:To study the clinical, imaging and pathological features of duodenal gangliocytic paraganglioma (DGP).Methods:The clinical, imaging and pathological data of patients with DGP treated at the Shandong Provincial Hospital Affiliated to Shandong First Medical University from January 2012 to October 2021 were retrospectively analyzed.Results:Of 8 patients with DGP, there were 7 males and 1 female, with a median age of 52 years (range 37 to 57 years). Five patients were asymptomatic and they were diagnosed on physical examination followed by investigations. Three patients presented with black stools. CT examination showed localized nodular thickening of the duodenum, with enhanced scanning showing obvious progressive contrast enhancement. Endoscopic ultrasonography showed a hypoechoic submucosal lesion in duodenal wall. Histologically, the neoplasm composed of three different cell types which included Schwann cells, epithelioid cells, and ganglioid cells. The Schwann cells expressed NF, NSE and S-100 proteins; the epithelioid cells expressed CK, NSE, Syn and CgA proteins; while the ganglioid cells expressed NSE, Syn, CgA and NF proteins. Endoscopic submucosal dissection was performed in 2 patients and surgical resection was performed in 6 patients.Conclusion:DGP is a rare benign neurogenic tumor which is most commonly found in the duodenum. It has a good prognosis. Imaging and endoscopic examinations demonstrated a submucosal mass. The main treatment are endoscopic resection and local surgical resection.

Objective:To investigate the current situation and needs of pharmaceutical training for general practice faculty.Methods:A self-designed questionnaire survey was conducted in April 2019. The participants were general practice faculty attending the national training course in Zhongshan Hospital and selected by convenience sampling method.Results:A total of 219 general practice teachers participated in the survey, 51.14% (112/219) of the participants thought that the current pharmaceutical knowledge did not meet the needs of pharmaceutical services in daily work, and 67.58% (148/219) attended pharmacy related training every year, and the frequency was mainly 1—2 times per year (56.62%, 124/219). The main reasons for attending the training were working needs (68.24%, 101/148) and willingness (55.41%, 82/148); 63.51% (94/148) of the participants thought that the training was moderate or less effective, mainly because of the weak strength of trainers (40.54%, 60/148), insufficient attention paid by trainers (37.16%, 55/148) and lack of depth (37.16%, 55/148). The survey showed that 76.26% (167/219) of general practice teachers had pharmaceutical training needs; and gender, working years and working experience in secondary and/or tertiary hospitals were influencing factors for pharmaceutical training needs. And female faculty, those working less than 10 years and with working experience in secondary hospitals had higher demand for pharmaceutical training. The expected pharmaceutical training focused primarily on the selection and optimization of medication schemes (72.60%, 159/219), interaction/incompatibility between medicines (62.10%, 136/219) and pharmaceutical care in medical treatment (57.08%, 125/219). The expected training methods were mainly interactive case analysis and discussion (69.41%, 152/219) through the internet or APP (such as WeChat) (54.34%, 119/219); the expected training frequency was no more than once in two months (36.07%, 79/219), better in working time (48.86%, 107/219) and each session was 30—45 minutes (38.36%, 84/219).Conclusion:General practice faculty has a high demand for pharmaceutical training. Targeted, individualized and systematic pharmaceutical training courses should be developed according to the pharmaceutical training needs of participants.
