ABSTRACT
This study collected epidemic data of COVID-19 in Zhengzhou from January 1 to January 20 in 2022. The epidemiological characteristics of the local epidemic in Zhengzhou High-tech Zone caused by the SARS-CoV-2 Delta variant were analyzed through epidemiological survey and big data analysis, which could provide a scientific basis for the prevention and control of the Delta variant. In detail, a total of 276 close contacts and 599 secondary close contacts were found in this study. The attack rate of close contacts and secondary close contacts was 5.43% (15/276) and 0.17% (1/599), respectively. There were 10 confirmed cases associated with the chain of transmission. Among them, the attack rates in close contacts of the first, second, third, fourth and fifth generation cases were 20.00% (5/25), 17.86% (5/28), 0.72% (1/139) and 14.81% (4/27), 0 (0/57), respectively. The attack rates in close contacts after sharing rooms/beds, having meals, having neighbor contacts, sharing vehicles with the patients, having same space contacts, and having work contacts were 26.67%, 9.10%, 8.33%, 4.55%, 1.43%, and 0 respectively. Collectively, the local epidemic situation in Zhengzhou High-tech Zone has an obvious family cluster. Prevention and control work should focus on decreasing family clusters of cases and community transmission.

Objective:To evaluate the predictive value of systemic immune inflammation index (SII) for short-term prognosis in patients with sepsis complicated with acute kidney injury who received continuous renal replacement therapy (CRRT) .Methods:From Feb. 2018 to Jan. 2022, 90 patients with sepsis complicated with acute kidney injury who received CRRT in Hangzhou Cancer Hospital were included as the research objects. According to the survival of patients within 90 days, they were grouped into a survival group of 60 cases and a death group of 30 cases. The clinical baseline data such as age, sequential organ failure assessment (SOFA) score, acute physiological function and chronic health status scoring system II (APACHE II), albumin (ALB) were recorded. Automatic blood cell analyzer was applied to detect lymphocyte count, platelet count and neutrophil count in peripheral venous blood of patients with sepsis complicated with acute kidney injury who received CRRT, and the SII was calculated; Pearson correlation analysis was performed to analyze the correlation between SII and clinical baseline data in dead patients with sepsis complicated with acute kidney injury receiving CRRT; ROC curve was drawn to analyze and compare the predictive value of SII, SOFA score and APACHEII for death in patients with sepsis complicated with acute kidney injury receiving CRRT; Kaplan-Meier curve was performed to describe the changes in patient survival; multivariate Cox regression analysis was performed to analyze the factors affecting 90-day death in patients with sepsis complicated with acute kidney injury receiving CRRT.Results:SII (2636.74), C-reactive protein (CRP) [ (92.45±29.74) mg/L], SOFA score (12.83±3.24) and APACHEII (28.30±7.51) in the death group were higher than those in the survival group [341.92, (50.24±16.13) mg/L, 10.00±3.12, 25.13±6.87], and ALB [ (2.50±0.53) g/dl] was lower than that in the survival group [ (2.79±0.61) g/dl] ( P<0.05). SII was significantly positively correlated with CRP, SOFA score and APACHEII, and significantly negatively correlated with ALB in patients with sepsis complicated with acute kidney injury who received CRRT ( P<0.05). The areas under the curve (AUC) of SII, SOFA score, and APACHEII for predicting death in patients with sepsis complicated with acute kidney injury who received CRRT were 0.936, 0.827, and 0.736, respectively, and AUC of SII prediction was greater than that of SOFA score and APACHEII ( P<0.05). The 90-day survival rate of patients with sepsis complicated with acute kidney injury who received CRRT in the high SII group (23/46, 50.00%) was lower than that in the low SII group (37/44, 84.09%) ( P<0.05). SII was an independent risk factor for death within 90 days in patients with sepsis complicated with acute kidney injury who received CRRT ( P<0.05) . Conclusion:SII can better predict the 90-day mortality risk of patients with sepsis complicated with acute kidney injury receiving CRRT, and assist clinical assessment of short-term prognosis.
ABSTRACT
To investigate the clinical characteristics of metastatic hormone sensitive prostate cancer and explore the strategy of combination of new endocrine drugs.In April 2019, an 69-year-old man was admitted to the First People’s hospital of Changzhou with "gross hematuria" . Physical examination showed prostatic hyperplasia with an unsmooth hard surface. CT showed a mass in bladder and possible metastasis in right lung. Diagnostic TUR-Bt pathology showed prostatic acinar adenocarcinoma, and PET-CT showed malignant lesion of prostate with bladder invasion, multiple pelvic lymph node metastasis and lung metastasis. The diagnosis of mHSPC with lymphatic and lung metastasis was considered. The patient was treated with bicalutamide and then switched to goserelin plus acetate abiraterone with prednisone. Total prostate specific antigen (tPSA) decreased to 0.705 ng/ml after 1 month of ADT+ AAP treatment, and decreased to 0.007 ng/ml after 4 months, and then maintained at 0.003 ng/ml until January 2021. Serum testosterone decreased to 0ng/dl and maintained the whole follow-up period. After 3 months of treatment, the pulmonary metastasis was not obvious. Till the last follow-up at January 2021, the patient reported good quality of life with no serious adverse events. The efficacy of ADT combined with acetate abiraterone in the treatment of mHSPC with lung cancer was significant.
ABSTRACT
Objective To investigate the effect of the posture analysis and intervention on the lower limb motor function of hemiplegic stroke survivors. Methods Forty hospitalized stroke survivors with hemiplegia were di-vided at random into a control group and an experimental group. The control group (n＝20) received conventional re-habilitation training. The experimental group (n＝20) additionally received therapy based on posture analysis. Before the treatment and after 2 and 4 weeks of treatment, Holden walking function grading was applied, along with Fugl-Meyer motor function rating, and the timed up and go test ( TUGT) was administered. Results After 2 weeks of treatment there were no statistically significant differences between the groups in terms of any of the measures. After 4 weeks of treatment the average Holden and Fugl-Meyer scores of the experimental group were significantly better than those of the control group, though there was still no significant difference in the two groups' average TUGT times. Conclusion Posture analysis-based intervention can improve the lower limb motor function of stroke patients with hemiplegia.

Methods:An Agilent TC-C18(2)(250 mm ×4.6 mm, 5 μm) column was used with the temperature of 30℃. The mobile phase consisted of 0. 8% tetrahydrofuran and the flow rate was 1. 0 ml·min-1 . The detection wavelength was set at 276nm. Results:The calibration curve of patulin was linear within the range of 1-20ng(r=1. 000 0), the average recovery was 92. 1% and RSD was 2. 2%(n=6). Conclusion:The method is simple, reliable and accurate, which can be used in the content determination of patulin in health foods containing hawthorn.
