Objective This paper intends to compare the efficacy and safety of high-dose dual regimens containing Vonoprazan and proton pump inhibitor in patients infected with Helicobacter pylori(H.pylori).Methods A prospective randomized controlled study was conducted.According to inclusion and exclusion criteria.,243 patients with H.pylori infection admitted to the Department of Gastroenterology,the First Hospital of Lanzhou University from February 2023 to December 2023 were enrolled as the research objects.They were randomly divided into two groups.The high-dose dual therapy containing Vonoprazan group(VPZ-HDDT group)was given Vonoprazan fumarate tablet 20mg twice daily plus amoxicillin 750 mg four times daily for 14 days and the high-dose combination group containing PPI(PPI-HDDT group)was given esomeprazole 40 mg twice daily plus amoxicillin 750 mg four times daily for 14 days.Patients were followed up and recorded by telephone or WeChat on the 7th and 14th day of starting treatment for drug intake and occurrence of adverse reactions.Patients were instructed to recheck the 13C or 14C urea breath test at least 1 month after the end of medication.Treatment by protocol(PP)analysis,modified intention to treat(mITT)and intention-to-treat(ITT)analysis were used for H.pylori eradication rates in both groups,and compliance and incidence of adverse reactions were compared between the two groups.Results The eradication rates of the VPZ-HDDT group and the PPI-HDDT group in the initial treatment were 94.0％and 88.5％(P=0.209)by PP analysis,and 91.8％and 87.5％(P=0.358)86.7％by mITT analysis,and 81.9％(P=0.377)by ITT analysis,respectively.In the retreated patients,the PP analysis and mITT analysis eradication rates in these two groups were consistent,87.0％and 84.2％(P=0.800),respectively,and 83.3％and 76.2％(P=0.550)by ITT analysis.For the refractory H.pylori patients,the PP analysis and mITT analysis eradication rates in these two groups were also consistent,71.4％and 50.0％(P=0.429),and the eradication rates of ITT analysis were 62.5％and 50.0％(P=0.640),respectively.In different stratifications,the eradication rates of the VPZ-HDDT group were higher than those of the PPI-HDDT group,but the differences were not statistically significant.The incidence of adverse reactions and compliance of the VPZ-HDDT group and the PPI-HDDT group were similar,with no statistically significant differences.Conclusion Both two combination regimens can achieve clinically acceptable eradication rates(＞85％)in the first-time treatment patients.For the retreated and refractory patients,the choice of vonoprazan is more beneficial.

Inflammatory bowel disease (IBD) is a formidable disease due to its complex pathogenesis. Macrophages, as a major immune cell population in IBD, are crucial for gut homeostasis. However, it is still unveiled how macrophages modulate IBD. Here, we found that LIM domain only 7 (LMO7) was downregulated in pro-inflammatory macrophages, and that LMO7 directly degraded 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase 3 (PFKFB3) through K48-mediated ubiquitination in macrophages. As an enzyme that regulates glycolysis, PFKFB3 degradation led to the glycolytic process inhibition in macrophages, which in turn inhibited macrophage activation and ultimately attenuated murine colitis. Moreover, we demonstrated that PFKFB3 was required for histone demethylase Jumonji domain-containing protein 3 (JMJD3) expression, thereby inhibiting the protein level of trimethylation of histone H3 on lysine 27 (H3K27me3). Overall, our results indicated the LMO7/PFKFB3/JMJD3 axis is essential for modulating macrophage function and IBD pathogenesis. Targeting LMO7 or macrophage metabolism could potentially be an effective strategy for treating inflammatory diseases.

Objective:To investigate the clinical efficacy of hip arthroscopy in the treatment of acetabular labral injury combined with cysts.Methods:A total of 14 patients (5 males and 9 females) aged 35.46±12.62 years (range, 26-57 years) with acetabular labral injury complicated with cyst who underwent hip arthroscopy in Department of Sports Injury and Arthroscopy, Tianjin Hospital from January 2017 to April 2022 were retrospectively analyzed. There were 8 cases of left hip and 6 cases of right hip with an average body mass index of 24.35±3.14 kg/m 2 (range, 20.2-28.4 kg/m 2). The duration of symptoms was 6.25±4.39 months (range, 3-11 months). All patients underwent hip arthroscopic cyst cleaning and glenoid labral suturing. The femoral neck α angle, lateral center rim angle, visual analogue score (VAS), Harris hip score (HHS), and international hip outcome tool scores (iHOT-12) were compared before and after operation. Results:All patients successfully completed the operation and were followed up for 10.23±2.45 months (range, 1.5-18 months). The difference between the patients' hip VAS before and after operation was statistically significant ( F=108.47, P<0.001). The VAS score at 18 months after operation was 1.34±0.83, which was significantly lower than that before operation 7.85±1.12 and at 6 weeks after operation 5.03±1.60 ( P<0.05). The difference between the patients' hip HHS scores before and after operation was statistically significant ( F=96.89, P<0.001). The HHS score at 18 months after operation was 85.58±4.65, which was significantly higher than that before operation 54.36±2.31 and 6 weeks after operation 61.12±1.20 ( P<0.05). The differences of iHOT-12 scores before and after operation were statistically significant ( F=117.92, P<0.001). The iHOT-12 score of 18 months after operation was 78.36±2.28 points, which was higher than that before operation 31.39±5.21 points and 6 weeks after operation 47.88±2.20 points, and the difference was statistically significant ( P<0.05). The difference of α angle of femoral neck before and after operation was statistically significant ( F=101.56, P<0.001). The α angle of femoral neck at 12 months after operation was 45.32°±3.16°, which was significantly lower than that before operation 50.86°±8.41° ( P<0.05). The difference of lateral center rim angle before and after operation was statistically significant ( F=100.38, P<0.001). The lateral center rim angle was 28.23°±5.32° at 12 months after operation, which was smaller than that before operation 32.16°±5.13°, and the difference was statistically significant ( P<0.05). Conclusion:Hip arthroscopy in the treatment of acetabular labral injury with cysts can relieve hip pain and improve hip function.

Pharmacy active consultation refers to the spontaneous activity that clinical pharmacists take the initiative to go to clinical departments to help doctors solve problems related to drug use in clinical practice ，put forward drug treatment suggestions or provide pharmaceutical services ，and form medical documents . The difference between pharmacy active consultation and pharmacy consultation is that the latter is generally proposed by the clinician ，who sends a consultation invitation to the pharmacy department in the hospital information system ，and the clinical pharmacist will go to the consultation after receiving it ，while the former is a pharmaceutical service mode that the clinical pharmacist takes the initiative to carry out in the clinical department . On the basis of routine pharmacy active consultation ，clinical pharmacists in our hospital also further carried out a special active consultation mode （including prompt special active consultation for patients with multidrug resistance bacteria positive ，active monitoring and intervention for patients with drug -induced liver injury ），and patient pharmaceutical supervision in the form of return visit of pharmacy active consultation . Pharmacy active consultation and its special active consultation possess the characteristics of initiative ， early and extensive coverage ，as a supplement to resident clinical pharmacy services . Pharmacy active consultation could help the pharmacy department to improve service efficiency ，provide a new perspective for medical institutions to carry out efficient pharmaceutical services ，and supply new ideas for the reform of pharmaceutical services in China .

The erythropoietin-producing hepatocellular receptor (Eph receptor) family is the largest subfamily in the receptor tyrosine kinase (RTK) families which mediates cell morphology, adhesion, movement, proliferation, survival, and differentiation by its bidirectional signals coupled with Ephrin ligands. EphA2 receptor is an important isoform which is involved in the pathological changes in cataract, breast cancer, etc. Previous studies found that the kinase domain of the EphA2 receptor binds to the plasma membrane, and its kinase activity is regulated by the plasma membrane. However, it is still unclear that the impact of the adjacent SAM domain on the membrane binding and kinase activities of kinase domain. In this study we purified the cytoplasmic kinase-SAM tandem of the EphA2 receptor by co-expression with the phosphatase PTP1B 1-301 fragment. Our results showed that the SAM domain of EphA2 receptor can further enhance the interaction between the kinase domain and liposomes (4 mg/mL) by 6 folds (P<0. 001). And the phosphorylation of kinase-SAM tandem can enhance its lipid (4 mg/mL) binding ability by 2. 5 folds (P < 0. 05). In addition, the lipid binding ability and tyrosine phosphorylation activities of kinase domain are mutual promoted, which creating a positive feedback loop in the two biological processes. In conclusion, our studies indicate that the kinase domain and the adjacent SAM domain can function as an intact unit, whose lipid binding ability and kinase activity are quite different from the individual kinase domain. Therefore, our results provide a biochemical basis for better understanding of the regulation mechanism of other Eph receptors in its kinase domain.

OBJECTIVES: Safe and effective anticoagulation is essential for hemodialysis patients who are at high risk of bleeding. The purpose of this trial is to evaluate the effectiveness and safety of two-stage regional citrate anticoagulation (RCA) combined with sequential anticoagulation and standard calcium-containing dialysate in intermittent hemodialysis (IHD) treatment. METHODS: Patients at high risk of bleeding who underwent IHD from September 2019 to May 2021 were prospectively enrolled in 13 blood purification centers of nephrology departments, and were randomly divided into RCA group and saline flushing group. In the RCA group, 0.04 g/mL sodium citrate was infused from the start of the dialysis line during blood draining and at the venous expansion chamber. The sodium citrate was stopped after 3 h of dialysis, which was changed to sequential dialysis without anticoagulant. The hazard ratios for coagulation were according to baseline. RESULTS: A total of 159 patients and 208 sessions were enrolled, including RCA group (80 patients, 110 sessions) and saline flushing group (79 patients, 98 sessions). The incidence of severe coagulation events of extracorporeal circulation in the RCA group was significantly lower than that in the saline flushing group (3.64% vs. 20.41%, P<0.001). The survival time of the filter pipeline in the RCA group was significantly longer than that in the saline flushing group ((238.34±9.33) min vs. (221.73±34.10) min, P<0.001). The urea clearance index (Kt/V) in the RCA group was similar to that in the saline flushing group with no statistically significant difference (1.12±0.34 vs. 1.08±0.34, P=0.41). CONCLUSIONS Compared with saline flushing, the two-stage RCA combined with a sequential anticoagulation strategy significantly reduced extracorporeal circulation clotting events and prolonged the dialysis time without serious adverse events.

The median age was 57 (19-64) years. In the neurological manifestations per se, all patients had headache, 16 patients had cerebral involvement, which included 8 cases at the frontal area, 8 cases at the temporal area, 8 cases at the skull base area (4 cases with parasellar involvements including 3 cases with cavernous sinus involvement and 2 cases with orbital involvement), 6 cases of tentorium involvement, 2 cases of cerebral palsy, 1 case of calvarium, 1 case of occipital, and 1 case with combined spinal pachymeningitis, respectively. In systemic manifestations, 10 patients had fever, 8 patients had weight lose, 4 patients had lung involvement, 3 patients had kidney involvement, 16 patients had nasosinusitis, 10 patients had tympanitis, and 16 patients had localized GPA. The laboratory tests showed that 15 patients had positive anti-neutrophil cytoplasmic antibodies (ANCA), including 8 cases with positive proteinase 3 (PR3)-ANCA and 6 cases with positive myeloperoxidase (MPO)-ANCA. Sixteen patients had lumbar puncture examination, 9 cases had elevated cerebrospinal pressure, 10 cases had elevated level of protein in cerebrospinal fluid. Nineteen patients were treated with glucocorticoids (12 patients accepted pulse therapy) and immunosuppressive agents. Twelve patients were treated with intrathecal injections of dexamethasone combined with or without Methotrexate (MTX). All 19 patients were improved.Conclusion:HCP, as a rare but serious manifestation of GPA, is not rare in active cases and should be intensively treated.

Objective To analyze the epidemiological characteristics of reported emergency public health events at schools from 2006 to 2013, and provide a scientific basis for better disposal of school-related events. Methods The reported emergency public health events at schools in Tianjin from 2006 to 2013 were collected, and descriptive epidemiological analysis was conducted on data. Results A total of 267 reported emergency public health events at school in Tianjin during 2006-2013, of which 257 infectious disease events, accounting for 96.25%. The incident occurred in primary schools and nurseries. The peak was from March to June and October to December for the incident. The top three species of disease onset were influenza (2 360 cases), chicken pox (2 032 cases) and mumps (1 813 cases). There was a correlation between the duration and interval from onset of the first case to report of emergency public health events(rs=0.522,P＜0.05). Conclusion In recent years, school public health emergency events are high momentum, mainly in rural areas, primary schools and nurseries. Timely detection and disposal of emergency public health events can reduce the harm generated by them.

The purpose of this study was to compare the efficacy of CEP plus G-CSF and CVP plus G-CSF regimens in the mobilization and collection of peripheral blood hematopoietic stem cells (PBHSC), and in the hematopoietic recovery. 57 patients with non-Hodgkin's lymphoma (NHL) underwent autologous PBHSC transplantation were analyzed retrospectively. The PBHSC were mobilized and collected by using CEP plus G-CSF and CVP plus G-CSF respectively, and were retransfused into these NHL patients after preconditioning, then the mobilization efficacy, adverse reactions and hematopoietic recovery were analyzed. The results showed that the WBC count decreased to ≤ 1.0 × 10(9)/L, platelet amount dropped to ≤ 40 × 10(9)/L during peripheral blood stem cell mobilization of all patients, which indicated successful collection of PBHSC. The mean value of (4.38 ± 3.40) × 10(8)/kg mononuclear cells (MNC) containing (2.79 ± 2.53) × 10(6)/kg CD34(+) cells were collected in CEP plus G-CSF group, while the mean value of (3.31 ± 1.23) × 10(8)/kg MNC containing (2.02 ± 0.87) × 10(6)/kg CD34(+) cells were collected in CVP plus G-CSF group. The efficacy of mobilization in CEP plus G-CSF group was significantly higher than that in CVP plus G-CSF group (p < 0.05). After preconditioning, bone marrow was suppressed in all patients. The average time of WBC count recovery to ≥ 1.0 × 10(9)/L was 11.4 days in CEP plus G-CSF group and 12.3 days in CVP plus G-CSF group; the average time of platelet amount recovery to ≥ 50 × 10(9)/L was 18.6 days in CEP plus G-CSF group and 19.3 days in CVP plus G-CSF group. The statistical analysis showed no significant difference in the average time of hematopoietic recovery between 2 groups. It is concluded that autologous PBHSC transplantation shows significant effect for treatment of patients with NHL. Either modified CEP or CVP plus G-CSF regimen is safe and effective in PBHSC mobilization. The CEP plus G-CSF regimen is better than CVP plus G-CSF regimen.

OBJECTIVETo evaluate the outcome of precision-fit surface hemiarthroplasty in the treatment of femoral head osteonecrosis.

METHODSThe clinical data of 41 patients (48 hip joints) with femoral head osteonecrosis were reviewed. Of them, 30 were male and 11 were female, average age was 37 years old (ranging from 29 - 49). Thirty-five patients were at Ficat stage III and 13 at Ficat stage IV, their acetabula were relatively normal. The 41 patients (48 hip joints) underwent precision-fit surface hemiarthroplasties.

RESULTSThe mean duration of follow-up was 5.2 years. The average UCLA hip score at follow-up was improved significantly from 3.1 to 9.1 points for pain, 4.4 to 9.2 points for walking, and 5.5 to 7.1 points for activity (P = 0.001). The satisfaction rate was 88.6% for 35 at Ficat stage III, 69.2% for 13 at stage IV (P = 0.25). Eight hips failed; the UCLA hip score was not improved significantly; the postoperative X-ray examination showed that 7 femoral prostheses were implanted in a varus orientation (the angle between the femoral prosthesis stem and the anatomic axis of the femoral shaft was lower than angle of 130 degrees). Five-year survival rate was 83.0%.

CONCLUSIONSPrecision-fit surface hemiarthroplasty of the hip has the satisfactory result in treatment of the femoral head osteonecrosis on the basis of observing strictly operative indications and improving operative technique.
