A 17-year-old young man with a history of swollen leg and intermittent jaundice was presented to Peking Union Medical College Hospital with acute fever and mental disturbance.He developed deep venous thrombosis,acute myocardial infarction and plantar skin necrosis during the past four years,and was presented with an acute episode of fever,thrombocytopenia,acute kidney injury,acute myocardial infarction,mental disturbance,and obstructive jaundice.Laboratory tests showed schistocytes on peripheral blood smear.High titer of antiphospholipid antibodies was detected.Strikingly,the activity of a disintegrin and metalloprotease with a thrombospondin type 1 motif,member 13 (ADAMTS13)was significantly decreased without the production of inhibitors.Images indicated stenosis of the common bile duct,common hepatic duct,and cystic duct,which caused dilation of bile ducts and the gall bladder.Corticosteroids and anticoagulation therapy were effective at first,but the disease relapsedonce the corticosteroids tapered down.Plasma exchange was administrated for 17 times,which was effective temporarily during this episode.Methylprednisolone pulse therapy,intravenous immunoglobulin,rituximab,anticoagulation therapy,and bile drainage,were all tried but still could not control the disease.The patient's family agreed to withdraw treatment after he developed septic shock.

Objective To analyze the bacterial distribution and resistance in upper urinary tract stone patients, then choose suitable antibiotics and reduce infectious complications accordingly.Methods Middle flow urine, infectious stone and the end of kidney drainage tube were taken for culture in 148 patients who underwent percutaneous nephrolithotomy between January 2009 to September 2010. Antibiotics were used according to the culture results and the complications secondary to infection were analyzed. Results Urinary pathogens presented in 38 (25.7%) patients before operation.There were 112 strains of bacteria. The predominant strains included: Escherichia coli (17 cases,11.5%), Staphylococcus epidermidis (4 cases) and Proteus mirabillis (4 cases). Escherichia coli and Proteus mirabillis were common in stone culture. Staphylococcus epidermidis (5 cases),Pseudomonas aeruginosa (5 cases) and Staphylococcus haemolytcus (5 cases) were found in renal drainage tube culture which were positive in 25 patients. Imipenem, cefepime, vacomycin, nitrofurinton were sensitive and commonly used antibiotics. Forty-one patients (27.7 %) had fever postoperatively, including 10 positive for middle urine culture and 9 positive for drainage tube culture. One infective shock was diagnosed postoperatively. Conclusions Gram-negative bacilli are predominant in the upper urinary tract stone patients preoperatively. Gram-positive ones are common postoperatively.Suitable antibiotics, based on middle flow urine culture, could reduce urinary infective complications.

Background/Aims: Ulcerative colitis (UC) is an incurable, relapsing-remitting inflammatory disease that increases steadily. Mucosal healing has become the primary therapeutic objective for UC. Nevertheless, endoscopic assessments are invasive, expensive, time-consuming, and inconvenient. Therefore, it is crucial to develop a noninvasive predictive model to monitor endoscopic activity in patients with UC. Methods: Clinical data of 198 adult patients with UC were collected from January 2016 to August 2022 at Huadong Hospital, China. Results: Patients with UC were randomly divided into the training cohort (70%, n=138) and the validation cohort (30%, n=60). The receiver operating characteristic curve value for the training group was 0.858 (95% confidence interval [CI], 0.781 to 0.936), whereas it was 0.845 (95% CI, 0.731 to 0.960) for the validation group. The calibration curve employed the Hosmer-Lemeshow test (p>0.05) to demonstrate the consistency between the predicted and the actual probabilities in the nomogram of these two groups. The decision curve analysis validated that the nomogram had clinical usefulness. Conclusions The nomogram, which incorporated activated partial thromboplastin time, fecal occult blood test, β2-globulin level, and fibrinogen degradation products, served as a prospective tool for evaluating UC activity in clinical practices.

Objective:To explore the effect of LILRB2 on the proliferation and apoptosis of colorectal cancer SW480 cells, and to further explore its mechanism.Methods:Colorectal cancer SW480 cells were cultured in vitro and divided into blank control group, negative control group and experimental group. The expression of LILRB2 was detected by flow cytometry. The expression of LILRB2 was detected by qPCR, and the empty vector plasmid and the LILRB2 plasmid were transfected into SW480 cells respectively; cell proliferation was detected by CCK-8 method; cell apoptosis was detected by flow cytometry. Western blot was used to detect changes in the expression of related proteins.Results:The expression level of LILRB2 in SW480 was 0.84 ± 0.09, twice higher than that in FHC cells (0.38 ± 0.05) , and the difference was statistically significant ( P<0.05) . After virus infection, the expression of LILRB2 (0.48 ± 0.07) in SW480 cells of the experimental group decreased significantly. CCK-8 experiment results showed that after 12 hours of treatment, the proliferation of SW480 cells in the LILRB2 low expression experimental group was inhibited, and the percentage of apoptosis in SW480 cells in the LILRB2 low expression experimental group increased to 49.3%±1.2%, which was statistically significant ( P<0.05) compared with the percentage of apoptosis in the blank control group and the negative control group (7.48%±0.85%, 7.35%±0.93%) . The ROS level of SW480 cells in the experimental group with low LILRB2 expression was significantly higher than that in the blank control group and negative control group ( P<0.05) . After adding ROS scavenger NAC, the apoptosis of LILRB2 in the experimental group increased. Conclusion:The low expression of LILRB2 inhibits the proliferation of SW480 cells and induces apoptosis, which may play a role by regulating the level of ROS, providing a theoretical basis for the study of LILRB2 in colorectal cancer.

Skull defect is one of the major sequelae of traumatic brain injury and decompressive craniectomy,which affects the prognosis of neurological function.Cranioplasty is the main method to treat skull defect.The surgical technique is relatively simple and has been widely performed in neurosurgical departments.Although the optimal timing of cranioplasty is still controversial,the author advocates early cranioplasty when the patent's condition permits.Different cranioplasty materials have their own advantages and disadvantages,so we should choose appropriate materials according to the specific conditions of patients.Full preoperative evaluation,reasonable operation and proper postoperative management are important means to prevent complications related to cranioplasty.In view of these problems,the author reviews the latest literature and progress in order to provide reference for standardizing clinical treatment.

Objective:To investigate the correlation between different serum uric acid (SUA) levels and impaired fasting glucose (IFG) in adults.Methods:From March 2019 to February 2020, 5006 adults in Wuxi area of Taihu Sanatorium in Jiangsu Province were selected as subjects. Quintile method was divided into the following five groups: Q1: SUA<270 μmol/L, Q2: 270 μmol/L SUA 318 μmol/L or less, Q3: 319 μmol/L ≤SUA≤360 μmol/L, Q4: 361 μmol/L SUA 410 μmol/L or less, and Q5: SUA>410 μmol/L. Correlation was analyzed by logistic analysis, with IFG as the outcome index, five SUA groups as the observation index, and gender, age, body mass index (BMI), blood lipid, and blood pressure as confounding factors. Three logistic regression analysis models were constructed to explore the relationship between different SUA level groups and IFG risk, as well as the influence of BMI on the risk correlation between SUA and IFG.Results:The BMI, DBP, FPG, TC, TG, and LDL-C all increased with the increase in SUA level; however, HDL-C gradually decreased with the increase in SUA level (P<0.01). The SUA levels among the five groups were positively correlated with fasting blood glucose level in the IFG group ( r=0.589, P<0.001). After adjusting for age, sex, and BMI, SUA level was strongly associated with fasting glucose in the IFG group ( r=0.534, P<0.001). After further adjustment for blood lipid and blood pressure, the correlation persisted ( r=0.523, P<0.001). With Q1 as the control group, the calculated OR values of IFG risk were 1.199, 2.660, 2.784 and 3.629, respectively. After further adjustment for various confounding factors, the calculated OR values of each group were 1.130, 2.389, 2.350 and 2.895, respectively. The IFG risk in the group with SUA level in the corresponding Q2 and Q5 groups was 1.13 times and 2.90 times higher, respectively, than that in the normal group, indicating that with the increase in SUA level, the IFG risk in the population increased. With the increase in BMI and SUA levels after BMI stratification, the mean fasting glucose level increased ( P<0.001). Conclusion:The SUA level and IFG risk are closely related. Increased SUA level increases IFG risk, and SUA and IFG are associated with weight gain, which should be paid attention to.

Objective:To develop a comprehensive ability evaluation system for general practice management post in community health service institutions.Methods:Based on the previous studies and literature search on competency of general practitioners in various clinical posts, the first draft of the comprehensive ability indicator system for general management posts was designed. From November 2019 to January 2020, the comprehensive ability indicator system, classification and scoring method and evaluation method for general management posts were determined through three rounds of Delphi consultation.Results:Seventeen experts with administrative management experiences were invited for consultation, including 3 directors in charge and 14 general practice managers. The response rate of valid questionnaires in the three rounds of consultation were all 17/17, the authority of experts were all>0.7, and the coordination coefficients of expert opinions were 0.142, 0.212, and 0.532 (all P<0.01). The 11 evaluation indexes of the comprehensive ability of community general management posts were: achievement orientation, initiative, interpersonal understanding, service consciousness, influence, organization, training others, teamwork, team leadership, professional skills and confidence. Methods suitable for evaluation the ability of psychological test indicators were achievement orientation, interpersonal understanding, service consciousness and self-confident;appropriate indicators for no-leader group discussion were initiation, influence, team work, team leadership;appropriate indicators for in-tray test ability were organized cognition, professional skills;and the appropriate indicator for the ability of the structured interview was training others. Conclusions:The comprehensive ability evaluation system for community general management posts established in this study is scientific and practical, which may provide objective standard basis for the ability evaluation of community health management talents.
