Objective To explore and analyze the clinical efficacy and adverse reactions of total glucosides of paeony (TGP) and vitamin B2 in the treatment of recurrent aphthous ulcers (RAU) . Methods 120 patients of RAU were randomly divided into TGP group and vitamin B2 group, 60 cases in each group. The TGP group received TGP capsules after meals, three times a day, 0.6g/d. Vitamin B2 group received vitamin B2 tablets, three times a day, 5mg/d, 8 weeks for one course. The ulcer change, visual analogue scale (VAS) and efficacy were observed. Results After treatment, the VAS scores were significantly reduced in two groups(P<0.05), and the above indicators of TGP group were better than vitamin B2 group(P<0.05). The total efficacy in TGP group was higher than that in vitamin B2 group (P<0.05). There was minor adverse reactions in TGP group and no significant adverse reactions in vitamin B2 group.Conclusion TGP has good efficacy and safety in the treatment of recurrent aphthous ulcers. The TGP has significant effect than that of vitamin B2.

Objective: To explore the feasibility of assessing complications registration through medical information. Methods: A descriptive case series study was performed to retrospectively collect medical information and complication registration information of gastric cancer patients at Department of Gastrointestinal Cancer Center Ward I, Peking University Cancer Hospital from November 1, 2016 to March 1, 2017 (the first period), and from November 1, 2018 to March 1, 2019 (the second period). Case inclusion criteria: (1) adenocarcinoma confirmed by gastroscopy and biopsy; (2) patients undergoing open surgery or laparoscopic radical gastrectomy; (3) complete postoperative medical information and complication information. Patients who were directly transferred to ICU after surgery and underwent emergency surgery were excluded. Because difference of the complication registration procedure at our department existed before and after 2018, so the above two periods were selected to be used for analysis on enrolled patients. The prescription information during hospitalization, including nursing, medication, laboratory examination, transference, surgical advice, etc. were compared with the current Standard Operating Procedure (SOP, including preoperative routine examinations, inspection, perioperative preventive antibiotic use, postoperative observational tests, inspection, routine nutritional support, prophylactic anticoagulation, and prophylactic inhibition of pancreatic enzymes, etc.) for gastric cancer at our department. Medical order beyond SOP was defined as medical order variation. Postoperative complication was diagnosed using the Clavien-Dindo classification criteria, which was divided into I, II, IIIa, IIIb, IVa, IVb, and V. Medical order variation and complication registration information were compared between the two periods, including consistence between medical order variation and complication registration, missing report, underestimation or overestimation of medical order variation, and registration rate of medical order variation [registration rate = (total number of patients–number of missing report patients)/total number of patients], severe complications (Clavien-Dindo classification ≥ III), medical order variation deviating from SOP and the corresponding inferred grading of complication. The data was organized using Microsoft Office Excel 2010. Results: A total of 177 gastric cancer patients were included in the analysis. The first period group and the second period group comprised 89 and 88 cases, respectively. The registrated complication rate was 23.6% (21/89) and 36.4% (32/88), and the incidence of severe complication was 2.2% (2/89) and 4.5% (4/88) in the first and the second period, respectively. The complication rate inferred from medical order variation was 74.2% (66/89) and 78.4% (69/88), and the incidence of severe complication was 7.9% (7/89) and 4.5% (4/88) in the first and second period, respectively. In the first and second period, the proportions of medical order variation in accordance with registered complication were 36.0% and 45.5% respectively; the proportion of underestimation, overestimation and missing report were 5.6% and 4.5%, 4.5% and 4.5%, 53.9% and 45.5%, respectively; the registration rate of medical order variation was 46.1% and 54.5%; the number of case with grade I complications inferred from medical order variation was 34 (38.2%) and 25 (28.4%), respectively; and the number of grade II was 12 (13.5%) and 15 cases (17.0%), respectively. The reason of the missing report of medical order variation corresponding to grade I complication was mainly the single use of analgesic drugs outside SOP, accounting for 76.5% (26/34) and 64.0% (16/25) in the first and second period respectively, and that corresponding to grade II complication was mainly the use of non-prophylactic antibiotics, accounting for 9/12 cases and 5/15 cases, respectively. Conclusions Medical information can evaluate the morbidity of complication feasibly and effectively. Attention should be paid to routine registration to avoid specific missing report.

Objective:To establish standard spatial brain template and ROIs template of 11C-methyl- N-2β-carbomethoxy-3β-(4-fluorophenyl)tropane (CFT) PET images for automated quantitative analysis of dopamine transporter (DAT) distribution. Methods:From May 2014 to December 2015, 11C-CFT PET and MRI T 1 brain images of 16 healthy volunteers (3 males, 13 females; age (63.3±6.9) years) from Huashan Hospital, Fudan University were co-registered and smoothed using statistical parametric mapping(SPM)5 software based on MATLAB to create a standard spatial brain template. The ROIs template was established by ScAnVp procedures. These templates were clinically verified by using 11C-CFT PET images of 37 healthy volunteers (23 males, 14 females; age (61.7±7.1) years), 32 Parkinson′s disease (PD) patients (20 males, 12 females; age (61.1±5.4) years), 10 multiple system atrophy with predominant parkinsonism (MSA-P) patients (7 males, 3 females; age (60.8±7.1) years) and 10 progressive supranuclear palsy (PSP) patients (5 males, 5 females; age (58.4±6.1) years) from Huashan Hospital, Fudan University between January 2014 and March 2019. One-way analysis of variance was used to analyze data. Results:Based on the 11C-CFT PET images and MRI T 1 images of healthy volunteers, a standard spatial brain template for normalization of 11C-CFT PET images was created. The ROIs template was established including seven regions: bilateral caudate, anterior putamen, posterior putamen (along the long axis) and the occipital cortex. The ROIs template was accurately aligned in each verification group. The normal reference values of semi-quantitative DAT distribution in caudate, anterior putamen and posterior putamen were obtained (1.84±0.13, 2.18±0.16, 1.77±0.11). The semi-quantitative values of 11C-CFT uptake in each ROI in patients were significantly lower than those in healthy volunteers ( F values: 49.79-283.83, all P<0.05). Conclusion:The established brain templates with accurate spatial alignment for 11C-CFT image analysis can provide foundational tools for the application of 11C-CFT PET imaging in clinical practice and scientific research.

The establishment of a high-quality gastric cancer database significantly improves the efficiency and standardization of diagnosis and treatment of this disease. Our center has developed a specialized, single-center gastric cancer database and initiated the China Gastrointestinal Cancer Surgery Union, catalyzing the exploration of multi-center databases. This article encapsulates multi-level experience and provides a detailed overview of the quality control methods we implement in both constructing and managing the gastric cancer database. Utilizing an electronic medical record system and a multi-disciplinary treatment (MDT) approach, we have designed the database in a modular and multi-nodal manner. A synthesis of automatic retrieval of structured data and manual entry, coupled with a rigorous MDT system and real-time supervision at various nodes, bolster our real-time quality control efforts. Ensuring data security and digitized management plans alongside real-time review protocol and a multi-level review system, we maintain the highest standards in the initiation and management of the database. Through the establishment of the China Gastrointestinal Cancer Surgery Union platform, we endorse the concept that multi-center database construction should be driven by research objectives, consider data accessibility, while placing an emphasis on building inter-center consensus on data quality control. Moving forward, it is crucial that the development of multi-center databases promotes uniformity in medical standards across centers, cultivates stable public data sharing platforms, ensures robust data security protocols, routinely conducts data quality assessments, and bolsters multi-center cooperation and exchanges to promote the homogeneity of medical standards.

OBJECTIVETo compare the short-term safety and costs between laparoscopic assisted or totally laparoscopic uncut Roux-en-Y and Billroth II((BII() + Braun reconstruction after radical gastrectomy of distal gastric cancer.

METHODSClinical data from our prospective database of radical gastrectomy were systematically analyzed. The patients who underwent laparoscopic gastrectomy with uncut Roux-en-Y or BII(+ Braun reconstruction between March 1st, 2015 and June 30th, 2017 were screened out for further analysis. Both the reconstructions were completed by linear staplers. Uncut Roux-en-Y reconstruction was performed with a 45 mm no-knife linear stapler (ATS45NK) on the afferent loop below the gastrojejunostomy. Continuous variables were compared using independent samples t test or Mann-Whitney U. The frequencies of categorical variables were compared using Chi-squared or Fisher exact test.

RESULTSEighty-one patients were in uncut Roux-en-Y group and 58 patients were in BII(+Braun group. There were no significant differences between uncut Roux-en-Y group and BII(+Braun group in median age (56.0 years vs. 56.5 years, P=0.757), gender (male/female, 52/29 vs. 46/12, P=0.054), history of abdominal surgery (yes/no, 10/71 vs. 4/54, P=0.293), neoadjuvant chemotherapy (yes/no, 21/60 vs. 11/47, P=0.336), BMI (thin/normal/overweight/obesity, 2/49/26/3 vs. 3/39/14/2, P=0.591), NRS 2002 score (1/2/3/4, 58/15/5/3 vs. 47/5/3/3, P=0.403), pathological stage (0/I(/II(/III(, 3/41/20/17 vs. 1/28/13/16, P=0.755), median tumor diameter in long axis (2.5 cm vs. 3.0 cm, P=0.278), median tumor diameter in short axis (2.0 cm vs. 2.0 cm, P=0.126) and some other clinical and pathological characteristics. There were no significant differences between uncut Roux-en-Y group and BII(+Braun group in morbidity of postoperative complication more severe than grade I([12.3% (10/81) vs. 17.2% (10/58), P=0.417], morbidity of anastomotic complication [1.2%(1/81) vs. 0, P=1.000] or hospitalization costs [(94000±14000) yuan vs.(95000±16000) yuan, P=0.895]. The median first time to liquid diet (57.1 hours vs. 70.8 hours, P=0.017) and median postoperative hospital stay (9 days vs. 11 days, P=0.003) of the patients in uncut Roux-en-Y group were shorter than those in BII(+Braun group.

CONCLUSIONLaparoscopic assisted or totally laparoscopic uncut Roux-en-Y reconstruction after radical gastrectomy of distal gastric cancer is safe and feasible with better recovery than BII(+Braun reconstruction.

Since the outbreak of Corona Virus Disease 2019 occurred in December 2019, the reduction of population mobility has curbed the spread of the epidemic to some extent but also prolonged the waiting time for the treatment of patients with gastric cancer. Based on fully understanding the different staging characteristics of gastric cancer, clinical departments should develop reasonable out-of-hospital management strategies. On one hand, reasonable communication channels should be established to allow patients to receive adequate guidance out of the hospital. On the other hand, shared decisions with patients should be made to adjust treatment strategies, and education on viral prevention should be implemented to minimize the impact of the epidemic on tumor treatment.
