OBJECTIVE To explore the relationship between peripheral blood interferon γ(IFN-γ)/interleukin-4(IL-4)and the short-term prognosis of children with Mycoplasma pneumoniae pneumonia(MPP),and to analyze the influencing factors for the short-term prognosis of children with MPP.METHODS A total of 170 children with MPP admitted to the hospital from Jan.2021 to Jan.2024 were selected(MPP group).Based on the condition 28 days after treatment,they were divided into a poor prognosis group(n=49)and a good prognosis group(n=121).Clinical data of the children were collected,and the levels of peripheral blood interleukin-4(IL-4)and inter-feron-γ(IFN-γ)were measured to calculate the IFN-γ/IL-4 ratio.Multivariate Logistic regression model was used to analyze the factors affecting the short-term prognosis of children with MPP.RESULTS In the poor prognosis group,the duration of antibiotic use,the proportion of pleural effusion,the proportion of extrapulmonary compli-cations,and the levels of peripheral blood IL-4 and IFN-γ were higher than those in the good prognosis group,while the IFN-γ/IL-4 ratio was lower than that in the good prognosis group(P＜0.05).Logistic regression re-sults showed that persistent fever,prolonged antibiotic use and the occurrence of extrapulmonary complications were risk factors for the short-term prognosis of children with MPP(P＜0.05),and a high IFN-γ/IL-4 ratio was a protective factor(P＜0.05).CONCLUSION Persistent fever,prolonged antibiotic use and extrapulmonary com-plications are risk factors for the short-term prognosis of children with MPP,and high IFN-γ/IL-4 values is a pro-tective factor.

BACKGROUND: Disease-modifying therapies have been approved for the treatment of relapsing multiple sclerosis (RMS). The present study aims to examine the safety of teriflunomide in Chinese patients with RMS. METHODS: This non-randomized, multi-center, 24-week, prospective study enrolled RMS patients with variant (c.421C>A) or wild type ABCG2 who received once-daily oral teriflunomide 14 mg. The primary endpoint was the relationship between ABCG2 polymorphisms and teriflunomide exposure over 24 weeks. Safety was assessed over the 24-week treatment with teriflunomide. RESULTS: Eighty-two patients were assigned to variant ( n  = 42) and wild type groups ( n  = 40), respectively. Geometric mean and geometric standard deviation (SD) of pre-dose concentration (variant, 54.9 [38.0] μg/mL; wild type, 49.1 [32.0] μg/mL) and area under plasma concentration-time curve over a dosing interval (AUC tau ) (variant, 1731.3 [769.0] μg∙h/mL; wild type, 1564.5 [1053.0] μg∙h/mL) values at steady state were approximately similar between the two groups. Safety profile was similar and well tolerated across variant and wild type groups in terms of rates of treatment emergent adverse events (TEAE), treatment-related TEAE, grade ≥3 TEAE, and serious adverse events (AEs). No new specific safety concerns or deaths were reported in the study. CONCLUSION: ABCG2 polymorphisms did not affect the steady-state exposure of teriflunomide, suggesting a similar efficacy and safety profile between variant and wild type RMS patients.

For muscle-invasive bladder cancer (MIBC) patients, preoperative neoadjuvant chemotherapy (NAC) can reduce the tumor stage, treat micrometastases, prolong the median survival, and improve the prognosis.However, NAC is associated with side effects such as renal impairment, thromboembolism and drug toxicity.NAC itself suffers from deficiencies such as renal function impairment, thromboembolism, and drug toxicity.Its therapeutic efficacy is affected by factors such as tumor pathology type, DNA repair gene defects, whether it is primary MIBC, and TNM staging, so there are certain limitations in its use.Based on the cisplatin treatment regimen, more and more studies are exploring the limitations and shortcomings of NAC in MIBC treatment regimen.Therefore, this paper provides an overview and outlook of the application of NAC in MIBC treatment.

Objective To explore the clinical utility of endoclip papilloplasty in endoscopic retrograde cholangiopancreatography(ERCP).Methods A prospective study was conducted and selected 62 patients who underwent ERCP from November 2021 to November 2022.30 out of 32 patients who randomly underwent endoclip papilloplasty were successful.These patients were assigned to successful endoclip papilloplasty group(group A,n=30)or the duodenal papilla unclamping group(group B,n=30).The aim was to compare the difference in short-term and long-term complications between the two groups.Results The success rate of papillary plasty was 93.8%(30/32),with no statistically significant differences observed in the incidence of postoperative pancreatitis,postoperative hemorrhage after ERCP,and postoperative cholangitis between the two groups(P>0.05).The duodenal perforation rate was 0.There were no significant differences between the two groups in terms of total cholangitis incidence and recurrence rate of calculus of common bile duct within 1 year(P>0.05).However,there was a statistical difference in terms of total the incidence of cholangitis+calculus of common bile duct recurrence within 1 year(P<0.05).Conclusion The endoclip papilloplasty exhibits a high success rate and safety and feasibility procedure reducing long-term recurrence rate of cholangitis and calculus of common bile duct in endoscopic papillary large balloon dilation(EPLBD)procedure.

Objective:To study the relationship of pathogenic bacteria in midstream urine culture and stone composition of patients characteristics with infection stones.Methods:Between January 2016 and December 2020, 989 patients with infectious stones who attended Tsinghua Chang Gung Hospital, affiliated with Tsinghua University, for surgical treatment were enrolled in the study. There were 545 male and 444 female patients, with the mean age (48±14) years. The left and right side stones were 396 and 333, respectively. There were 260 bilateral stones, 264 single stones, 334 multiple stones, and 391 deer-stalker-shaped stones. The maximum diameter of stones was (33.4±26.5)mm, combined with diabetes in 109 cases and hypertension in 235 cases. Clean middle-urine was collected for bacterial culture, and intraoperative stone specimens were collected by percutaneous nephrolithotomy (PCNL). Personal characteristics of the patient such as gender, age, body mass index, clinical information such as stone size, location, comorbidities, results of urine culture and stone composition were recorded. The differences of infectious stone composition was analyzed between urease-producing, non-urease-producing bacteria.Results:Among the 989 patients with infectious stones, 259 were pure infectious stones, 131 were mixed infectious stones, and 599 were combined with infectious stone components. Urine cultures were positive in 627(63.4%) patients with infectious stones. The predominant urease-producing bacteria included Ureaplasma urealyticum(94 case), Proteus mirabilis(58 case), and Staphylococcus spp.(36 case). Pure infectious stones were common in Proteus mirabilis, while combined with infectious stone components were common in Ureaplasma urealyticum and Staphylococcus spp. The predominant non-urease-producing bacteria included Escherichia coli(175 case), Enterococcus spp.(76 case) and Streptococcus spp.(35 case). Escherichia coli commonly contained in infectious stone components and pure infectious stones, whereas Enterococcus spp. and Streptococcus spp. commonly contained in infectious stone components. Escherichia coli (61 case), Proteus mirabilis (44 case) and Enterococcus spp.(20 case) were the most common bacteria in 259 cases of pure infectious stones. Escherichia coli (36 case), Enterococcus spp. (14 case) and Ureaplasma urealyticum (10 case) were the most common bacteria in 131 cases of mixed infectious stones. The most common bacteria in 599 cases of combined infectious stones were Escherichia coli (78 case), Ureaplasma urealyticum (68 case) and Enterococcus spp. (42 case).Conclusions:Urease producing bacteria were not common in infectious stones. It was common for the Ureaplasma urealyticum in combined infectious stone components, while Escherichia coli was common in pure and combined infectious stone components.

Objective:To explore the status and influencing factors of peripherally inserted central catheters (PICC) related thrombosis in lung cancer patients undergoing chemotherapy.Methods:From June to December 2020, a total of 259 lung cancer patients undergoing chemotherapy in the First Affiliated Hospital of Zhengzhou University were enrolled using the convenient sampling method, and the occurrence of PICC related thrombosis within 3 months was recorded. Patients were divided into the thrombus group (18 cases) and the non-thrombosis group (241 cases) according to the occurrence of PICC associated thrombus. Univariate and multivariate Logistic regression analysis were used to explore the influencing factors of PICC related thrombosis in lung cancer patients undergoing chemotherapy.Results:The incidence of PICC related thrombosis of 259 lung cancer patients undergoing chemotherapy was 6.95% (18/259). Univariate analysis showed that there were significant differences in lung cancer stage, pathological type, complications, catheter placement limb, central venouscatheter material, catheter tip position, fibrinogen (Fg) and D-dimer (D-D) between the thrombosis group and the non-thrombotic group ( P<0.05). Multivariate Logistic regression analysis showed that Ⅲ-Ⅳ stage lung cancer, polyurethanecatheter, catheter tip position was 2/3 upper of the superior vena cava, Fg>4 g/L and D-D>0.4 mg/L were the influencing factors of PICC related thrombus in lung cancer patients undergoing chemotherapy ( P<0.05) . Conclusions:PICC related thrombosis in lung cancer patients undergoing chemotherapy is related to lung cancerstage, central venous cathetermaterial, catheter tipposition, Fg and DD. Medical staff should select appropriate catheter materialfor the patients, monitor coagulation-related factors closely, so as to reduce the risk of PICCrelated thrombosis.

Objective:To understand the clinical characteristics of rivaroxban-related adverse events (AE) in perioperative patients.Methods:The relevant databases at home and abroad (as of April 20, 2020) were searched and the case reports of AE associated with rivaroxban used during perioperative period were collected. Relevant information in patients (nationality, gender, age, medical history, application of rivaroxaban, combined drugs, and the occurrence, treatment, and outcome of AE, etc.) was extracted and analyzed descriptively.Results:A total of 42 case reports of AE caused by rivaroxban during perioperative period were collected, involving 46 patients from 11 countries. Of the 46 patients, 25 (54.3%) were male and 21 (45.7%) were female with an age of 16-96 years. In terms of the reasons for medication, 34 patients used rivaroxban before operation for prevention of postoperative venous thrombosis, 7 used rivaroxban after operation for prevention atrial fibrillation, stroke, or systemic thrombosis after operation, 4 discontinued rivaroxban during perioperative period, and 1 did not explain the reason for using rivaroxban. Past medical history were described in 21 patients, including hypertension, hyperlipidemia, and diabetes, etc. Combined medication was described in 22 patients, including antibiotics, non-steroidal anti-inflammatory drugs, analgesics, cardiovascular and cerebrovascular drugs, etc. The onset time of AE was recorded in 31 patients, which was 2 hours to 2 months after medication and most within 1 month. AE associated with rivaroxban were bleeding in 29 patients, liver injury in 7 patients, anaphylaxis in 6 patients, kidney injury in 3 patients, thrombosis in 3 patients, thrombocythemia in 2 patients, thrombocytopenia, pulmonary embolism, acute attack of coronary atherosclerotic heart disease, and visual loss in 1 patient each. After the occurrence of AE, 31 patients were improved after rivaroxban withdrawn, switching to other anticoagulants, and receiving symptomatic treatment; 1 patient improved after changing concomitant medications as well as reducing the dose of rivaroxban; 2 patients did not stop the drug in time and developed new allergic reaction; 2 patients were improved after using rivaroxban again; 1 patient died of hemorrhagic shock due to gastrointestinal bleeding; 9 patients′ outcome were unknown. Among the 46 patients, 18 had medication errors, of which 16 had dose error and 2 had compatibility errors.Conclusions:Hemorrhage is the most common AE related to rivaroxban in the perioperative use of rivaroxban, which mainly occurs within 1 month after medication. The overall prognosis is good after rivaroxban withdrawal, switching to other anticoagulants, and symptomatic treatment. Medication error is one of the causes of AE related to rivaroxban in perioperative period.

Objective:To discuss the influence of mindfulness-based stress reduction plus micro-class education on the complications and knowledge mastery rate in surgical patients with diabetes mellitus.Methods:A total of 105 patients, diagnosed as diabetes mellitus complicated with appendicitis in the Affiliated Hospital of Chengde Medical College were selected from January 2019 to January 2020. They were hospitalized for laparoscopic appendectomy and were randomly divided into the control group ( n = 52) and the study group ( n = 53) in accordance with the random number table. The patients in the control group were given routine nursing care, and the patients in the study group were given mindfulness decompression therapy combined with micro-classroom education. The blood glucose control and psychological emotion of the two groups before and after operation, and the postoperative complications and the mastery rate of disease knowledge of the two groups were compared. Results:There was no significant difference in blood glucose indexes between the two groups at baseline ( P>0.05); FBG, HbA1c and other indicators in the two groups were improved during operation and 24h after operation, but FBG (7.38±0.54) mmol/L, HbA1c (6.39±0.21)% and FBG (6.90±0.52) mmol/L and HbA1c (6.10±0.39)% in the study group were lower than those in the control group [(8.16±1.21) mmol/L, (7.53±1.05)%, (7.60±0.57) mmol/L, (6.50±0.41)%], the difference was statistically significant ( t value was 6.789-13.264, P < 0.05); there was no significant difference in SAS and SDS scores between the two groups at baseline ( P > 0.05), until discharge, the SAS and SDS scores of the treatment group were 35.81±5.49 and 42.08±4.91 respectively, which were significantly lower than those of the control group (42.21±5.53, 6.51±4.72) respectively, compared with the corresponding scale scores of the control group, the difference between the two groups after treatment was statistically significant ( t value was 5.386, 4.265, P < 0.05). Compared with 17.31% (9/52) of the control group, the incidence of complications in the study group decreased to 5.66% (3/53), there was significant difference ( χ2 value was 6.789, P < 0.05). The qualified rate of disease knowledge mastery in the study group (98.11%,52/53) was significantly higher than that in the control group (86.53%, 45/52), and the difference was significant ( χ2 value was 5.062, P < 0.05). Conclusion:The mindfulness-based stress reduction plus micro-class education can effectively control the laparoscopic appendectomy patients blood glucose, stabilize the mental emotions, increase the illness knowledge mastery degree, keep in good mood, reduce the postoperative complications and promote the fast recovery.
