Objective:
To investigate the changes of microorganisms and metabolites in joint effusion of patients with Rheumatoid arthritis(RA), Osteoarthritis(OA) and Urarthritis(UA). To provide new ideas for the study of the effect of microbiota on the pathogenesis of arthritis.
Methods:
Joint effusion samples were collected from 20 patients with RA, 20 patients with OA, and 20 patients with UA. 16S rRNA gene sequencing and untargeted ultra-high performance Liquid chromatography-mass spectrometry(LC-MS) were used to explore the differences in microorganisms and metabolites among the three groups. Pearson correlation analysis was used to detect the correlation between effusion microbiota and metabolites.
Results:
There were differences in microbial diversity and microbiota composition among the three groups. Combined with VIP>1 from OPLS-DA andP<0.05 from two-tailed Students t-test, 45 differential metabolites(Between RA and OA groups), 38 differential metabolites(Between UA and OA groups) and 16 differential metabolites(Between RA and UA groups), were identified. GO analysis and KEGG pathway analysis showed that the differential metabolic pathways among the three groups were mainly concentrated in citric acid cycle(TCA cycle), nucleotide metabolism, amino acid metabolism and glycolysis pathway. Correlation analysis of joint effusion microbiota and metabolites suggested that bacteria enriched in the three groups of joint effusion, such asPrevotella,Clostridium ruminosus,Prevotellaceae_UCG-001, were related to many key metabolites such as lysozyme, uric acid, glucose, and L-glutamine.
Conclusion
This study shows that there are a variety of bacterial flora in joint cavity effusion of RA, OA, and UA patients, and the differential metabolites produced by them are involved in the pathogenesis of the three types of arthritis by affecting a variety of metabolic pathways.

Objective:To construct and validate a risk prediction model for immune checkpoint inhibitor-associated pneumonia (CIP) using machine learning algorithms and the nomogram, aiming to provide an accurate and intuitive method to assist nurses in screening people at high risk of developing CIP.Methods:This was a retrospective case -control study. A total of 230 oncology patients treated with immune checkpoint inhibitors attending Zhujiang Hospital of Southern Medical University from January 2019 to February 2022 were collected using the hospital's electronic medical record system. The prediction models were built using five machine learning algorithms and nomogram. The models were then validated on a separate test set, and their differentiation and stability were assessed using evaluation indices like AUC and accuracy rate.Results:Underlying lung disease, smoking history, serum albumin≤35 g/L and radiotherapy history were identified as important influencing factors of CIP in all six models. The AUC of K nearest neighbor, support vetor machines (SVM), naive Bayesian, decision tree and random forest models predicted CIP were 0.647, 0.696, 0.930, 0.870, and 0.934, respectively. The AUC of the model created by the nomogram was 0.813, which was lower than the best random forest model in the machine learning algorithm, but with good predictive performance (AUC=0.934).Conclusions:The nomogram model can assess the patient′s risk more intuitively, but the risk prediction model of CIP based on a machine learning algorithm has a higher diagnostic value. It is suggested that the accuracy and usefulness of the prediction model can be increased by combining the nomogram's foundation with the machine learning algorithm.

【Objective】 To explore the recruitment and retention strategy of blood donors by investigating the age composition of blood donors in some areas of China, so as to promote blood donation and enhance clinical blood supply. 【Methods】 Through the working platform of Practice Comparison Working Group of China’s Mainland Blood Collection and Supply Institutions, the average age and age composition of blood donors from 22 blood centers were collected, and statistical analysis was conducted after eliminating invalid data. 【Results】 The median average age of blood donors during the survey year was 30.02.The median age in 2.89% of the blood centers was lower than 25. The average age of different genders was statistically significant only in 2018(P<0.05). Fot first-time blood donors, the median constituent ratio of donors <25 and ≥25 years old was 54.53% and 44.28%, with median retention rate at 10.30% and 9.61%, respectively. The median overall participation rate of blood donors was 2.7%, with median participation rate of blood donors <25 years old at 5.1%. 【Conclusion】 The recruitment and retention of blood donor is crucial to enhance clinical blood supply. Blood donors <25 years old, with a longer period for future donation, should be the main target of blood donation recruitment. Meanwhile, the revision of upper age limit for blood donation is another important initiative to grow the blood donor pool.

Acupuncture is an ancient therapeutic method based on the theory of Chinese medicine (CM). Traditional acupuncture has many limitations; it is subjective and relies more on the experience of an acupuncturist, and the efficacy is sometimes irreproducible. In contrast, electroacupuncture (EA) has special characteristics in terms of objectivity and stability, thereby gaining considerable attention. Parameter setting plays a crucial role in EA practice. The current paper summarizes the current situation and limitations of parameter setting in EA practice. Objectification is the tendency and future of CM as well as EA. With the development of computerized technologies, such as wearable sensors, vast data, and artificial intelligence, CM syndromes can be successfully objectified. We propose the development of a novel self-feedback-adjust EA system, which may improve the parameter setting in EA and be beneficial to both the patients and clinicians.

Plunging ranula is rare and manifests as the submandibular or submental cystic mass, without intra-oral abnormality. It usually causes misdiagnosis and malpractice. This article reported a case of plunging ranula that appeared as a massive mass located behind the left ear. A 6-year-old child presented with recurrent left retroauricular swelling over six months without obvious inducement. The mass showed repeatedly swelling and persistent skin ulcers. Physical examinations described a fluctuant, nontender mass behind the left ear whose size was about 5 cm×5 cm×3 cm. The skin upon the surface of the mass was thin and red, and overflowed yellow slimelike contents. Computed tomography (CT) showed an extensive cystic lesion in the left neck. After local incision and drainage the mass was shrink. With the primary clinical diagnosis of branchial cyst, the patient underwent mass resection through postauricular incision. During the operation, the fistula was traced to the area around the sublingual gland, and the postoperative pathology report demonstrated cystic spaces occurring in soft tissue without lymphoid tissue. One month postoperatively, the patient presented the "egg-white", wire-drawing transparent viscous fluid outflowing from the left external auditory canal, indicating that the fluid in the external auditory canal originated from the sublingual gland and the disease was the plunging ranula presenting as a giant left retroauricular mass. We readmitted the patient to the hospital and the ipsilateral sublingual gland was completely removed in the mouth under general anesthesia. No clinical evidence of recurrence was found at the end of 9 months follow-up. So far, there is no literature reporting plunging ranula behind ear. This case report describes the clinical manifestation, diagnosis, and differential diagnosis and treatment of a case of plunging ranula, and reveals that, other than the submandibular or submental, plunging ranula also could be found in retroauricular region. The plunging ranula is difficult to fully confirm through a clinical character, and usually easy to be misdiagnosed as other tumors, like lymphatic malformation, venous malformations, etc. Radiographic examination and/or puncture fluid observation are required for identification. "Egg-white", wire-drawing mucous secretion is the most important characteristic in clinical diagnosis of sublingual gland cyst. However, if sublingual gland resection, i.e. removal of the source of cyst fluid is performed, a good prognosis can be achieved.

In recent years, as the level of economic life has improved, the incidence of gestational diabetes mellitus has increased year by year. Gestational diabetes mellitus (GDM) has been a serious threat to maternal and newborn health. The pathogenesis of gestational diabetes is not very clear, and may be closely associated with insulin resistance, genetic susceptibility, inflammatory response, metabolic disorders. According to the gestational diabetes diagnostic standard,24-28 weeks pregnant women keep an empty stomach over 8 h, taken 75 g oral glucose directly, and then receive the oral glucose tolerance test. GDM is diagnosed as fasting blood-glucose> 5.1 mmol · L-1,1-hour postprandial blood glucose>10.0 mmol · L-1,and 2-hour postprandial blood glucose>8.5 mmol · L-1. Western medicine treatment is mainly based on diet, exercise, drugs, education, monitoring and insulin therapy according to blood glucose. Meanwhile, GDM is a type of diabetes in traditional Chinese medicine. GDM is prevented and treated with diets and traditional method sports and Chinese herbs. Therefore, integrated Chinese and western medicine therapy can maximize the curative effect, reduce the incidence of gestational diabetes mellitus, and effectively improve the adverse outcome and prognosis of patients with gestational diabetes mellitus from mother to child.

Objective To analyze the clinicopathological features of type 2 diabetes mellitus complicated with colorectal cancer (DCRC). Methods A case?control study was conducted. Inclusion criteria: (1) hospitalized patients receiving fibrocolonoscopy; (2) adenocarcinoma and mucinous adenocarcinoma diagnosed by pathology; (3) with preoperative cTNM clinical staging; (4) colorectal cancer patients undergoing surgical treatment; (5) with postoperative pTNM staging; (6) no smoking or drinking habits. Exclusion criteria: (1) familial adenomatous polyposis (FAP); (2) Lynch syndrome; (3) carcinoma of anal canal and perianal carcinoma; (4) multiple primary cancer; (5) with serious cardiocerebrovascular diseases or multiple organ failure. Clinicopathlogical data of 32 DCRC patients who were diagnosed and treated in Peking University Shougang Hospital from December 2017 to December 2018 were retrospectively collected and analyzed. Forty nondiabetic colorectal cancer (CRC) patients during the same period were selected as control group according to the sex ratio and the age difference less than 5 years. Student′s t test and χ2 test were used to compare the difference between the two groups in baseline clinicopathological data, clinical test results, tumor markers and infiltration status of T cells in tumor immune microenvironment. Results Among 32 DCRC patients, 24 were males and 8 were females with a mean age of (63.0±1.7) years; among 40 CRC patients, 30 were males and 10 were females with a mean age of (60.5 ± 1.6) years. The duration of diabetes mellitus in DCRC patients (from the diagnosis of diabetes mellitus to the diagnosis of colorectal cancer) was (9.2±1.3) years. The body mass index (BMI) of DCRC group was significantly higher than that of CRC group [(24.8±0.6) kg/m2 vs. (23.2±0.4) kg/m2, t=2.372, P=0.020]. There were no significant differences in other baseline data (sex, age, primary site of tumor, R0 resection rate, pathological stage, pathological type, differentiation degree of tumor, preoperative intestinal obstruction) between the two groups (all P>0.05). Serum triglyceride level in DCRC group was higher than that in CRC group [(2.1 ± 0.2) mmol/L vs. (1.5 ± 0.1) mmol/L, t=3.085, P=0.003], while hemoglobin [(120.3±5.2) g/L vs. (132.7±2.8) g/L, t=-2.224, P=0.029], anti? thrombin III [(94.2±3.7)% vs. (103.5±2.4)%, t=-2.197, P=0.031], and red blood cell count [(4.2±0.1)×1012/L vs. (4.5±0.1)×1012L, t=-2.055, P=0.044] were all lower than those in CRC group. The preoperative carcinoembryonic antigen (CEA) level in DCRC group was higher than that in CRC group [(50.3±21.8) μg/L vs. (5.6±1.0) μg/L, t=2.339, P=0.022]. There were no significant differences in preoperative levels of other four tumor molecular markers (CA199, CA242, CA724 and CA125) between the two groups (all P>0.05). The expression of Foxp3 [specific markers of CD4+, CD25+ regulatory T cells (Treg)] in DCRC group was higher than that in CRC group [(82.7±6.2) cell/ HPF vs. (62.6±4.9) cell/HPF, t=2.586, P=0.012]. There were no significant differences in the infiltration of CD4, CD8, PD?1 and PD?L1 positive cells between two groups (all P>0.05).Conclusions The average diabetic history of DCRC patients is nearly 10 years. They have higher BMI and serum CEA level, and more Treg cell infiltration in the tumor. Close attention should be paid to these patients in clinical practice.
