The COVID-19 epidemic has spread to the whole world for three years and has had a serious impact on human life, health and economic activities. China's epidemic prevention and control has gone through the following stages: emergency unconventional stage, emergency normalization stage, and the transitional stage from the emergency normalization to the "Category B infectious disease treated as Category B" normalization, and achieved a major and decisive victory. The designated hospitals for prevention and control of COVID-19 epidemic in Tianjin has successfully completed its tasks in all stages of epidemic prevention and control, and has accumulated valuable experience. This article summarizes the experience of constructing a hospital infection prevention and control system during the "Category B infectious disease treated as Category A" period in designated hospital. The experience is summarized as the "Cluster" hospital infection prevention and control system, namely "three rings" outside, middle and inside, "three districts" of green, orange and red, "three things" before, during and after the event, "two-day pre-purification" and "two-director system", and "one zone" management. In emergency situations, we adopt a simplified version of the cluster hospital infection prevention and control system. In emergency situations, a simplified version of the "Cluster" hospital infection prevention and control system can be adopted. This system has the following characteristics: firstly, the system emphasizes the characteristics of "cluster" and the overall management of key measures to avoid any shortcomings. The second, it emphasizes the transformation of infection control concepts to maximize the safety of medical services through infection control. The third, it emphasizes the optimization of the process. The prevention and control measures should be comprehensive and focused, while also preventing excessive use. The measures emphasize the use of the least resources to achieve the best infection control effect. The fourth, it emphasizes the quality control work of infection control, pays attention to the importance of the process, and advocates the concept of "system slimming, process fattening". Fifthly, it emphasizes that the future development depends on artificial intelligence, in order to improve the quality and efficiency of prevention and control to the greatest extent. Sixth, hospitals need to strengthen continuous training and retraining. We utilize diverse training methods, including artificial intelligence, to ensure that infection control policies and procedures are simple. We have established an evaluation and feedback mechanism to ensure that medical personnel are in an emergency state at all times.

Objective:To construct the nursing sensitive quality index system for interventional treatment of trigeminal neuralgia, so as to provide reference for the nursing quality evaluation and management of interventional treatment of trigeminal neuralgia.Methods:From June to December 2022, using the "Structure-Process-Results" quality evaluation model as the theoretical framework, an expert inquiry questionnaire was developed based on literature review. The indicator system was established using the Delphi method, and the weights of the indicators were determined using the analytic hierarchy process.Results:The recovery rates of the two rounds of expert correspondence questionnaires were 92.6% (25/27) and 100.0% (25/25), the expert authority coefficients were 0.860 and 0.888, the Kendall's coordination coefficients were 0.073 and 0.058 ( P<0.05), and the coefficient of variation were 0-0.330 and 0-0.191, respectively. Finally, the nursing sensitive quality index system for interventional treatment of trigeminal neuralgia was formed, which included three primary indexes, 14 secondary indexes and 54 tertiary indexes. Conclusions:The index system has strong scientific and clinical applicability, which can provide reference for nursing quality evaluation and management of interventional treatment of trigeminal neuralgia.

Objective:To investigate the prognostic value of 18F-fluorodeoxygen-D-glucose-positron emission tomography /computerized tomography ( 18F-FDG-PET-CT) in Hodgkin′s lymphoma (HL) at the end of first-line treatment (PET-end), by comparing the ratio of maximum standardized uptake value (SUV max) of lesion and liver SUV (rLL), SUV max reduction between baseline PET (PET-0) and PET-end (ΔSUV max), and Deauville 5-point scale (5-PS). Methods:Patients with HL newly treated in our hospital from August 2006 to December 2015 were retrospectively analyzed. All the patients enrolled in the study underwent post-treatment FDG PET-CT. The rLL and ΔSUV max were calculated, and all the cases were scored using Deauville 5-PS. The receiver operating characteristic (ROC) approach was applied to identify the optimal cut-point value, and survival curves according to different PET-CT assessment methods were estimated using the Kaplan-Meier analysis. The prognostic efficacy of different PET-CT assessment methods was compared, and DeLong test was used to verify it. Kaplan-Meier method and multivariate analysis using the Cox proportional hazards model were performed to analyze the potential independent risk factors. Results:There were 5 patients progressed within a 3-year follow-up. In the three PET-CT assessment methods, the predictive value of rLL and Deauville 5-PS were significant effective. ROC analysis for rLL as a progression predictor showed an optimal cut-point of 1.29. Deauville 5-PS=4 and rLL=1.29 showed the best prognostic accuracy. The sensitivity of rLL and Deauville 5-PS were both 80.0%, and the specificity of each was 98.0% and 93.7%, respectively. The positive predictive value (PPV) and negative predictive value (NPV) of rLL were 66.7% and 98.7%, while the PPV and NPV of 5-PS were 44.4% and 98.7%. The 3-years progression-free survival (PFS) rates of rLL≥1.29 group and rLL<1.29 group were 33.3% and 98.7%, with significant difference ( P<0.001). The 3-years PFS rates of post-treatment Deauville 5-PS<4 group and Deauville 5-PS≥4 group were 98.7% and 55.6%, with significant difference ( P<0.001). The prognostic evaluation efficacy of rLL was positively correlated with that of Deauville 5-PS ( r=0.75, P<0.05). Area under curves (AUC) of rLL and Deauville 5-PS were 0.93 (95% CI: 0.825-1.000) and 0.91 (95% CI: 0.757-1.000), respectively. DeLong test showed the significant difference between the two methods ( P<0.05). The univariate analysis results showed that clinical baseline stage, post-treatment rLL and Deauville 5-PS were associated with the prognoses of HL patients ( P<0.05). The multivariate analysis results showed that post-treatment rLL and Deauville 5-PS were independent prognostic factors of HL ( P<0.05). Conclusions:The rLL and Deauville 5-PS are potential prognostic factors for HL response assessment. The new semi-quantitative method rLL has methodological advantages over visual analysis, and it is a good supplement for Deauville 5-PS. rLL can improve prognostic evaluation accuracy of PET-CT and is useful to early identify patients with HL at a high risk of relapsing after first-line treatment.

OBJECTIVE: Pyrotinib, a novel irreversible pan-ErbB receptor tyrosine kinase inhibitor, showed promising antitumor activity and acceptable tolerability in phase II and phase III randomized clinical trials. We assessed the activity and safety of oral pyrotinib for human epidermal growth factor receptor 2 (HER2) positive metastatic breast cancer patients in the real world. METHODS: We retrospectively analyzed 72 HER2 positive metastatic breast cancer (MBC) patients who received oral pyrotinib based regimens at Beijing Cancer Hospital and other four hospitals (Peking University First Hospital, China-Japan Friendship Hospital, General Hospital of PLA, Peking University Third Hospital) from August 2018 to September 2019. Progression free survival (PFS), objective response rate (ORR), adverse events (AE) of pyrotinib were investigated. RESULTS: Seventy-two patients with HER2 positive MBC were enrolled. The median age of the patients was 55 years (range: 32-79 years). Sixty-nine (95.8%) patients had received anti-HER2 treatment in the metastatic and/or (neo) adjuvant settings; 61 (84.7%) patients had received anti-HER2 treatments in the metastatic setting in terms of trastuzumab 56 (77.8%) patients, lapatinib 36 (50.0%) patients, and T-DM1 4 (5.6%) patients. Among these 72 patients who received oral pyrotinib based regimens, 62 (86.1%) patients received pyrotinib (±trastuzumab) in combination with chemotherapy, 6 (8.3%) patients received pyrotinib (± trastuzumab) in combination with endocrine therapy and 4 (5.6%) patients received pyrotinib (±trastuzumab). Sixty-five (90.3%) patients received 400 mg pyrotinib once daily as initial dose, and 7 (9.7%) patients received 320 mg. OBJECTIVE response and safety to pyrotinib based therapy were evaluable in all the 72 patients. One (1.4%) patient achieved complete response (CR), 18 (25.0%) patients achieved partial response (PR), 41 (56.9%) patients had stable disease (SD), and 12 (16.7%) patients had progressive disease (PD). The ORR (CR+PR) was 26.4% and the median PFS was 7.6 months (95%CI: 5.5-9.7 months). Among the 36 patients with prior lapatinib therapy, the median PFS was 7.9 months (95%CI: 4.1-11.7 months). Among the 15 patients with brain metastasis, the median PFS was 6.0 months (95%CI: 2.2-9.8 months). The main toxicities related to pyrotinib were diarrhea in 57 (79.2%) cases, and 48 (66.7%) cases with grade 1-2 as well as 9 (12.5%) cases with grade 3. CONCLUSION Pyrotinib based therapy is an effective treatment for patients with HER2 positive MBC, including patients with lapatinib treatment failure and brain metastasis, and the toxicities can be tolerated.

Objective:To investigate the compliance of statins and influencing factors in population with cardiovascular risks in the community.Methods:One hundred and eighty-six residents with cardiovascular disease risks in a community of Tianjin were recruited from June 2017 to October 2017. The Chinese revised version of the compliance Morisky scale was used to assess the compliance, and the influencing factors were analyzed.Results:Among all subjects 119 were prescribed with statins (64.0%,119/186) , of whom 7.6% (9/119) did not take the drug. According to the risk assessment of arteriosclerotic cardiovascular disease (ASCVD) in the next 10 years, among the 110 subjects taking the medicine, there were 18 subjects with intermediate risk and 92 with high risk. The subjects with good compliance accounted for 30.0% (33/110), and those with poor compliance accounted for 70.0% (77/110). Univariate analysis showed that education level, occupation, and drug types were significantly associated with statin compliance ( P<0.05). Multivariate logistic regression analysis showed that higher education level and fewer total drug users were correlated with better compliance ( OR=3.530 and 0.388, P<0.05) . The reasons for subjects not taking medicine were fearing of adverse reactions ( n=6, 6/9) , and thinking no symptoms and no need to have medication ( n=3, 3/9).The reasons of poor medication adherence were thinking no symptoms and no need to have medication ( n=31, 40.2%), thinking ineffectiveness of medication ( n=28, 36.4%), fearing of adverse reactions ( n=16, 20.8%), and economic pressure ( n=2, 2.6%). Conclusions:The proportion of residents with poor compliance of statins is high in the community. It is suggested that targeted interventions and standardized management for subjects with cardiovascular risks should be conducted based on the related factors found in the study.

OBJECTIVETo explore the effect of Compound Tufuling Granules ([characters: see text], CTG) on regulating glucose transporter 9 (GLUT9) expression in the kidney to influence the uric acid excretion by the kidney and serum uric acid (SUA) level in hyperuricemia mice.

METHODSSixty Kunming male mice were randomly divided into the control group, model group, benzbromarone group, and CTG high-, middle- and low-dose groups. The yeast extract and uricase inhibition method were used to build hyperuricemia model, and the corresponding drugs were administrated on the 7th day. On the 21st day the 24-h urine was collected, on the 22nd day the blood was collected, the SUA level was detected by uricase colorimetry, and the mRNA and protein expressions of GLUT9 were detected by quantitative real-time polymerase chain reaction and Western blot, respectively.

RESULTSCompared with the model group, the levels of SUA and the mRNA and protein expressions of GLUT9 were significantly decreased, and the fraction excretion of uric acid (FEUA) was significantly increased in the CTG groups and benzbromarone group (all P<0.05). There was no significant difference in the above indicators between the CTG high-dose group and benzbromarone group (P>0.05). SUA is positively related to the GLUT9 mRNA and protein expressions in the kidney (P<0.05 or P<0.01).

CONCLUSIONSCTG can significantly reduce the SUA and increase the FEUA. In addition, CTG can effectively inhibit the mRNA and protein expressions of GLUT9 in the kidney of hyperuricemia mice to inhibit the uric acid re-absorption, promote uric acid excretion and reduce SUA.

BACKGROUNDRecent studies have shown that T helper type-2 (Th2) cells can induce the apoptosis of CD4+CD25+ Treg cells or resist the immunosuppressive effect of Treg cells. We hypothesize that an imbalance of Th2/Treg is present in patients with allergic asthma.

METHODSTwenty-two patients with mild asthma, 17 patients with moderate to severe asthma, and 20 healthy donors were enrolled. All patients were allergic to house dust mites. The proportion of peripheral blood CD4+CD25+ Treg cells and Th2 cells were determined by flow cytometry. The concentration of interleukin (IL)-10, transforming growth factor (TGF)-β and IL-4 in plasma was determined by enzyme linked immunosorbent assay. In these subjects, peripheral blood mononuclear cells from 17 mild asthmatic patients, 13 moderate to severe asthmatic patients and 14 healthy donors were acquired and expression of forkhead box P3 (Foxp3) and GATA-3 mRNA was detected by reverse-transcriptase polymerase chain reaction.

RESULTSCompared with healthy donors and patients with mild asthma, the percent of CD4+CD25+ Treg cells and plasma IL-10 levels were decreased in patients with moderate to severe asthma. There were no significant differences in Foxp3 mRNA expression among three groups, but a downward trend seen among patients with asthma. However, the percent of Th2 cells, IL-4 levels and expression of GATA-3 mRNA was markedly higher in patients with mild and moderate to severe asthma than in the control group. The ratio of Th2/Treg and their cytokines was increased in allergic asthma, especially for moderate to severe asthma. The ratio of GATA-3/Foxp3 mRNA was also increased in allergic asthma. In patients with moderate to severe asthma, the percentage of peripheral blood Treg cells was negatively correlated to the percentage of Th2 cells and IL-4 levels.

CONCLUSIONSThe decline of CD4+CD25+ Treg cells in patients with moderate to severe asthma may play an important role in progress of the disease. Furthermore, the deficiency of CD4+CD25+ Treg cells was associated with the over-expression of Th2 response.

BACKGROUNDIncreasingly, evidence from population, clinic-based and laboratory studies supports an independent association between obstructive sleep apnea syndrome (OSAS) and an increased risk of type 2 diabetes; however, this observation has yet to be replicated in China and the potential mechanisms that link these two conditions are not clear.

METHODSA total of 179 Han Chinese subjects were enrolled in this study. All subjects underwent polysomnography, the oral glucose tolerance-insulin releasing test (OGTT-IRT) and serum HbA(1)c measurement. Indexes including homeostasis model assessment-IR (HOMA-IR), Matsuda index, HOMA-β, early phase insulinogenic index (ΔI(30)/ΔG(30)), AUC-I(180) and oral disposition index (DIo) were calculated for the assessment of insulin resistance and pancreatic β-cell function.

RESULTSBased on OGTT, 25.4%, 44.6% and 54.5% subjects were diagnosed having glucose metabolic disorders respectively in control, mild to moderate and severe OSAS groups (P < 0.05). Serum HbA(1)c levels were highest in subjects with severe OSAS (P < 0.05). In contrast, compared with normal subjects, HOMA-β, ΔI(30)/Δ(G30) and DIO were lower in severe OSAS group (P < 0.05). In stepwise multiple linear regressions, 0-min glucose and HbA(1)c were positively correlated with the percentage of total sleep time below an oxyhemoglobin saturation of 90% (T90) (Beta = 0.215 and 0.368, P < 0.05); 30-min and 60-min glucose was negatively correlated with the lowest SpOO(2) (LSpO(2)) (Beta = -0.214 and -0.241, P < 0.05). HOMA-β and DI(O) were negatively correlated with T90 (Beta = -0.153 and -0.169, P < 0.05) while body mass index (BMI) was the only determinant of HOMA-IR and Matsuda index.

CONCLUSIONSOSAS is associated with impairment in glucose tolerance and pancreatic β-cell function in Han Chinese subjects while insulin sensitivity is mainly determined by obesity.
