Objective: To observe and compare the clinical effects of different electroacupuncture waveforms on primary dysmenorrhea. Methods: This was a prospective, randomized, three-group, parallel-controlled trial. Participants with primary dysmenorrhea were randomly divided into dense-sparse wave, continuous wave, and discontinuous wave groups in a 1:1:1 ratio. Two lateral Ciliao (BL 32) points were used. All three groups started treatment 3–5 days before menstruation, once a day for six sessions per course of treatment, one course of treatment per menstrual cycle, and three menstrual cycles. The primary outcome measure was the proportion with an average visual analog scale (VAS) score reduction of ≥50% from baseline for dysmenorrhea in the third menstrual cycle during treatment. The secondary outcome measures included changes in dysmenorrhea VAS scores, Cox Menstrual Symptom Scale scores and the proportion of patients taking analgesic drugs. Results: The proportion of cases where the average VAS score for dysmenorrhea decreased by ≥50% from baseline in the third menstrual cycle was not statistically significant (P > .05). Precisely 30 min after acupuncture and regarding immediate analgesia on the most severe day of dysmenorrhea, there was a statistically significant difference in the dense-sparse wave group compared with the other two groups during the third menstrual cycle (P < .05). Additionally, there was a statistically significant difference between the dense-sparse wave and discontinuous wave groups 24 h after acupuncture (P < .05). Conclusions Waveform electroacupuncture can alleviate primary dysmenorrhea and its related symptoms in patients. The three groups showed similar results in terms of short- and long-term analgesic efficacy and a reduction in the number of patients taking analgesic drugs. Regarding achieving immediate analgesia, the dense-sparse wave group was slightly better than the other two groups.

[Objective]To explore the mechanism of Guizhi Fuling Pill's treating ischemic stroke(IS),subarachnoid hemorrhage(SAH),mild cognitive impairment(MCI),insomnia disorder(ID),epilepsy(EP)and vascular headaches through"treating different diseases with the same method",by using network pharmacology and molecular docking.[Methods]The active components and targets of Guizhi Fuling Pill were screened out and obtained from Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP),Swiss Target Prediction database and PubChem platform.The targets of disease were searched from DrugBank,Disease Gene Network(DisGeNET),Genome Annotation Database Platform(GeneCards)and Online Mendelian Inheritance in Man(OMIM).Then the common targets of drug-disease were obtained,Cytoscape 3.9.1 software was used to construct a"drug-disease-component-target"network and protein-protein interaction(PPI)network.Gene ontology(GO)function enrichment and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analysis of common targets were carried out by Metascape database.AutoDock Vina software was used to verify the molecular docking of core components and key targets.[Results]After screening and deleting duplicates,155 core active ingredients of Guizhi Fuling Pill,672 related targets,196 disease targets and 78 drug-disease common targets were obtained.There were 5 core active ingredients in Guizhi Fuling Pill's"treating different diseases with the same method"for encephalopathy,which were paeonol,quercetin,paeoniflorin,cinnamaldehyde and amygdalin.There were 5 key targets obtained by PPI screening which were interleukin-6(IL6),tumor necrosis factor(TNF),insulin(INS),RAC-alpha serine/threonine-protein kinase(AKT1),interleukin-1 beta(IL1B).KEGG pathway enrichment analysis showed that the key pathways were lipid and atherosclerosis,fluid shear stress and atherosclerosis,pathways in cancer,advanced glycation end products-receptor of advanced glycation end products(AGEs-RAGE)signaling pathway in diabetic complications,Alzheimer's disease and pathways of neurodegeneration-multiple diseases.The molecular docking results showed that the key targets had good binding activity to the core active components.[Conclusion]The possible mechanism of multi-component,multi-target and multi-pathway of Guizhi Fuling Pill's treating encephalopathy through"treating different diseases with the same method"was expounded,which provided a theoretical basis and reference for further understanding the mechanism of Guizhi Fuling Pill and exploring new clinical application and experimental exploration.

ObjectiveTo explore the association between dietary retinol intake and prognosis of patients with esophageal squamous cell carcinoma. MethodsThe study enrolled 388 cases with primary esophageal squamous cell carcinoma that was pathologically diagnosed in the first affiliated hospital of Fujian medical university and the cancer hospital of Fujian medical university from July 2014 to August 2019. Chi-square test was used to determine the relationship between retinol and patients' characteristics. Kruskal-Wallis rank sum test was used to analyze the relationship between retinol and multiple nutrients. Cox proportional hazards regression model was used to explore the association between dietary retinol and esophageal squamous cell carcinoma. ResultsPatients with esophageal squamous cell carcinoma did not significantly differ in gender， age， TNM stage， tumor length or nutrient intake by different retinol intakes （P>0.05）. Multivariate Cox regression analysis showed that the high retinol intake group had a better prognosis （overal survial：HR=0.279，95%CI：0.150‒0.520，P<0.001；disease-free survival：HR=0.306，95%CI：0.181‒0.516，P<0.001）. ConclusionHigh dietary retinol intake may improve the prognosis of patients with esophageal squamous cell carcinoma.

Objective:To explore the damage of panretinal photocoagulation (PRP) to the subbasal nerve plexus (SNP) and its related mechanisms by comparing SNP changes in wide-field mosaic between before and after PRP treatment in diabetic patients.Methods:A randomized controlled study was conducted.Fifty-seven patients (114 eyes) with type 2 diabetes mellitus and binocular diabetic retinopathy (DR) stage IV to receive PRP treatment in Shanxi Eye Hospital from April to November 2019 were enrolled.The subjects were randomly divided into horizontal-vertical laser group and vertical-horizontal laser group according to a random number table.Twenty-nine eyes from 29 patients were assigned to the horizontal-vertical laser group with the photocoagulation sequence of temporal-nasal-inferior-superior.Twenty-eight eyes from 28 patients were assigned to the vertical-horizontal laser group with the photocoagulation sequence of inferior-superior-temporal-nasal.The severer eyes of each subject were chosen as the treatment eye and the contralateral eyes were chosen as the control eye.Corneal confocal laser scanning microscopy (CCM) was performed before PRP treatment, 1 week after each photocoagulation, and 1 month after the completion of PRP treatment to collect images of the SNP over an area of 2-3 mm around the whorl-like pattern.Captured images at each time were merged into one image by using the Photoshop CC 2017 image processing software, and then the nerve fiber length (NFL) of whorl-like pattern was measured by Neuron J image analysis software.McGill pain questionnaire was used to investigate the pain of patients after each photocoagulation.The NFL changes of SNP at different time points were compared between different eyes and different photocoagulation sequence groups.The study protocol adhered to the Declaration of Helsinki and was approved by an Ethics Committee of Shanxi Eye Hospital (No.201804b). Written informed consent was obtained from each patient prior to entering the study cohort.Results:After PRP treatment, there were different degrees of neural structure loss of SNP nerve fibers in 11 treatment eyes, but there was no significant change in SNP nerve fibers in the control eyes.There were significant differences in NFL between the treatment eyes and the control eyes at various time points ( Feyes=2.020, P=0.039; Ftime=4.062, P=0.001). In the horizontal-vertical laser group, different degrees of neural structure loss on the photocoagulation side were found in SNP nerve fibers after the first and second photocoagulation.In the vertical-horizontal laser group, different degrees of neural structure loss on the photocoagulation side were found in SNP nerve fibers after the third and fourth photocoagulation.There was no significant difference in NFL of treatment eyes between the two groups ( Fgroup=0.099, P=0.754), but there was a significant difference in NFL at various time points before and after treatment ( Ftime=5.231, P<0.001). There were 9 (9/57) patients who complained of pain after PRP, which occurred at the first time of photocoagulation in 7 of them. Conclusions:SNP damage may occur after PRP in patients with DR, and SNP is prone to be damaged on the photocoagulation side when performing horizontal photocoagulation.

Objective: The role of planned neoadjuvant radiotherapy or chemoradiotherapy in the non-radical resection of esophageal squamous cell carcinoma was unclear. The study aimed to evaluate their therapeutic effect and analyze the prognostic factors. Methods: We retrospectively analyzed the clinical data of locally advanced esophageal squamous cell carcinoma who received neoadjuvant radio therapy (33 patients) and concurrent chemoradiotherapy (119 patients) from January 2004 to December 2016 in our single-institution database.The survival rates were calculated by Kaplan-Meier method. The prognostic factors were analyzed by using Log rank test and Cox proportional hazards model. Results: The median follow-up was 29.8 months. One hundred and one patients survived more than 3 years. The rates of overall survival (OS) and disease-free survival (DFS) at 3 years were 63.9% and 55.6%, respectively.The rates of complete, partial and minimal pathological response of the primary tumor were 50.3%, 38.4%, 11.3%, the corresponding 3-year OS were 75.5%, 57.4%, 27.3% (P<0.001) and 3-year DFS were 72.0%, 44.7%, 17.6% (P<0.001), respectively.The postoperative lymph node metastasis rate was 27.0%. The 3-year OS and DFS of the lymph node positive group was 45.6% and 32.8%, significantly lower than 70.8% and 63.7% of the negative group (both P<0.001). The 3-year OS and DFS of pathologic stage Ⅰ, Ⅱ, ⅢA, ⅢB and Ⅵ A were 76.2%, 57.4%, 64.7%, 35.0%, 33.3% (P<0.001) and 70.1%, 49.3%, 41.2%, 22.1%, 33.3% (P<0.001), respectively.The operation-related mortality was 3.3%. Multivariate analysis showed that chest pain, postoperative respiratory failure, pathological differentiation, more than 15 lymph node dissection and ypTNM stage were the independent prognostic factors of OS (P<0.05 for all). Conclusions The planned neoadjuvant radiotherapy or chemoradiotherapy for the non-radical resection of advanced esophageal squamous cell carcinoma could result in favorable survival. The chest pain, postoperative respiratory failure, pathological differentiation, the number of lymph node resection and ypTNM stage are the independent prognostic factors of the prognosis of these patients.

Objective To evaluate the value of MR DWI combined with dynamic contras-t enhanced (DCE)scanning in the differential diagnosis of orbital lymphoma and inflammatory pseudotumor.Methods The clinical and imaging data of 1 5 cases with orbital lymphoma and 10 cases with inflammatory pseudotumor confirmed by surgery and pathology were analyzed retrospectively.25 patients were performed with conventional MR scanning,DWI scanning and DCE scanning.ADW4.7 software was used for DWI images and DCE images pos-t processing for analyzing the two groups of lesions in the TIC subtyping.Independent sample t test statistical analysis was used for comparing two groups of ADC values and Tmax values.The ROC curve was used for determining the statistically significant differences in measurement data of the threshold.With pathologic and immunohistochemical results as the gold standard,the accuracy,sensitivity and specificity of DWI combined with DCE in the diagnosis of orbital lymphoma and inflammatory pseudotumor were further detected.Results Among the 1 5 patients with orbital lymphoma,8 cases (8/15)occurred in the lacrimal gland area,5 cases (5/1 5)occurred in the outer cone space and 2 cases (2/15)occurred in the eyelid.Among the 10 patients with inflammatory pseudotumor,6 cases (6/10)occurred in the lacrimal gland and 4 cases (4/10)in the bulb.Among the 25 patients,9 of them had the TIC curve of outflow,6 of them had the TIC curve of platform and 10 of them had the TIC curve of inflow.The ADC value of orbital lymphoma was (0.573 ±0.1 1 6)×10－3 mm2/s,and the Tmax value was (248.2±1 59.4)ms.The ADC value of inflammatory pseudotumor was (1.186±0.244)×10－3 mm2/s,and the Tmax value was (5 5 7.6 ±98.7)ms.With the ADC＝0.885×10－3 mm2/s for the threshold,the AUC was 0.9 3 6 ,with diagnostic accuracy of 9 1.3%, the sensitivity of 90.1% and specificity of 80%.With the Tmax＝481.2 ms as the threshold,the AUC was 0.927,with the diagnosis accuracy rate of 88%,the sensitivity of 80%,and the specificity of 86.7%. Finally,DWI combined with DCE could reach the AUC 0.945, diagnostic accuracy of 89.5%,sensitivity of 93.3%,and specificity of 82.6%.Conclusion Conventional MRI scan combining DWI with DCE could show the histological components of the lesion of orbital tumor,which is of certain significance for the qualitative diagnosis of orbital lymphoma and inflammatory pseudotumor.

BACKGROUND: Surgeons are the direct decision-makers and performers in the surgical treatment of patients with lung cancer. Whether the differences among doctors affect the survival of patients is unclear. This study analyzed the five-year survival rates of different thoracic surgeries in patients undergoing surgery to assess the physician's impact and impact. METHODS: A retrospective analysis of five years between 2002-2007 in the Department of Thoracic Surgery, Cancer Hospital, Chinese Academy of Medical Sciences, for surgical treatment of lung cancer patients. According to different surgeons grouping doctors to compare the basic information of patients, surgical methods, short-term results and long-term survival differences. RESULTS: A total of 712 patients treated by 11 experienced thoracic surgeons were included in this study. The patients have nosignificant difference with gender, age, smoking, pathological type between groups. There were significant differences in clinical staging, surgery type, operation time, blood transfusion rate, number of lymph node dissection, palliative resection rate, postoperative complications and perioperative mortality. There was a significant difference in five-year survival rates among patients treated by different doctors. This difference can be seen in all clinical stage analyzes with consistency. In the multivariate analysis, it was suggested that surgeon was an independent factor influencing the prognosis of patients. CONCLUSIONS Thoracic surgeon has a significant effect on the therapeutic effect of lung cancer patients.
