Methods: Field epidemiological approaches including case definition development, searching for contacts, distribution of diseases description, environmental sampling and laboratory testing. Results: A total of 16 influenza like cases were included, all concentrated in the one class of grade two, including 15 students and 1 teacher. Among student cases, the incidence rate was 36.59% (15/41), the average age was 7.4 years, the incidence rate was 36.84%(7/19) for boys, 36.36%(8/22) for girls. The clinical course was 5-15 days, with the median of 9 days, and 18.75%(3/16) of the cases stayed studying while sick. The nasopharyngeal swab specimens in 16 cases all tested positive for influenza B, of which 11 tested positive for mycoplasma pneumoniae and 1 case also tested positive for coronavirus OC43. Body temperature, number of mononuclear cells, and treatment time of patients infected with Influenza B and mycoplasma pneumoniae were higher than those of patients infected with influenza B alone( P <0.05). The outbreak lasted for 12 days, all sick students were treated and discharged from hospital, with no severe cases or death, and the outbreak was effectively controlled. Conclusion This campus cluster outbreak caused by influenza B and mycoplasma pneumoniae. Patients with influenza B with mycoplasma pneumoniae have severe symptoms and a long course of illness, suggesting the importance of early management of the epidemic.

Objective:To explore the efficacy of the application of surface gastrointestinal pacing treatment in bedside blind placement of gastrointestinal intubation in patients with severe nervous system diseases and ultimately help clinical nursing staff optimize the intubation process and increase the success rate of post-pyloric placement.Methods:This study was a randomized controlled study. A total of 70 patients with severe nervous system diseases who were admitted to ICU of Jinhu People ′s Hospital from February 2022 to January 2023 were selected by successive sampling method and numbered according to the time sequence of admission, and were divided into The control group with 35 cases and observation group with 35 cases according to the random number table method. The control group used the routine bedside blind placement of gastrointestinal intubation and received metoclopramide intramuscular injection and gastric air injection to promote gastrointestinal peristalsis, while the observation group received surface gastrointestinal pacing treatment to promote gastrointestinal peristalsis. The differences in success rate, incubation time and pain degree of post-pyloric placement of gastrointestinal intubation were compared between the two groups. Results:The success rate of post-pyloric placement was 51.42% (18/35) in the control group and 82.85% (29/35) in the observation group, and the difference was statistically significant ( χ2=7.83, P<0.01). The incubation time of the control group was (15.83 ± 3.93) min, and the Critical Care Pain Observation Tool (CPOT) scored (3.32 ± 0.63) points, while the incubation time of the observation group was (3.78 ± 0.81) min, and the CPOT scored (1.03 ± 0.22) points, the differences between the two groups were statistically significant ( t=13.16, 14.65, both P<0.01). Conclusions:The application of surface gastrointestinal pacing treatment in bedside blind placement of gastrointestinal intubation to promote gastrointestinal peristalsis in patients with severe nervous system diseases can increase the success rate of post-pyloric placement of gastrointestinal intubation, reduce incubation time, alleviate pain. All in all, it is worthy of clinical application.

OBJECTIVE: To assess the inhibitory effect of the extract of Xanthoceras sorbifolium Bunge flower against benign prostatic hyperplasia (BPH) and explore its possible mechanism. METHODS: MTT assay was used to examine the effect of the extract of Xanthoceras sorbifolium Bunge flower on proliferation of benign prostatic hyperplasia cells (BPH-1), and cell apoptosis and cell cycle changes following the treatment were analyzed using annexin V/PI double staining and flow cytometry. The protein expression levels of Bcl-2, Bax, caspase-3, PI3K and AKT in the treated cells were detected using Western blotting. A rat model of BPH established by subcutaneous injection of testosterone propionate was treated with the flower extract for 28 days, and pathological changes in the prostate tissue were observed with HE staining. The protein expression levels of Bcl-2, Bax, caspase3 and PI3K/AKT in the prostate tissue were detected with Western blotting. RESULTS: Within the concentration range of 125-1000 µg/mL, the flower extract of Xanthoceras sorbifolium Bunge significantly inhibited the proliferation of BPH-1 cells and caused obvious cell cycle arrest at G0/G1 phase; the apoptotic rate of the cells was positively correlated with the concentration of the flower extract (P < 0.05). Bcl-2, p-PI3K and p-AKT expression levels were significantly down-regulated and Bax and caspase-3 expression levels were significantly increased in the cells after treatment with the flowers extract (P < 0.05). In the rat models of BPH, the rats treated with the flowers extract at moderate and high doses showed obviously decreased expressions of p-AKT and Bcl-2 and an increased expression of Bax in the prostate tissue; a significantly lowered p-AKT expression was observed in the prostate tissue of rats receiving the low-dose treatment (P < 0.05). CONCLUSION The flower extract of Xanthoceras sorbifolium Bunge has a inhibitory effect on BPH both in vitro and in rats, suggesting its potential value in the development of medicinal plant preparations for treatment of BPH.

Abstract: Due to the continued emergence of multiple variants of SARS-CoV-2, the ongoing pandemic has resulted in severe mortality over the past two years. After the Alpha, Beta, Gamma and Delta variants, the most recent new variant of concern (VOC) strain to emerge is Omicron (B.1.1.529), which evolved as a result of the accumulation of a large number of mutations. The Omicron variant, which has a much higher transmission rate than the Delta variant, soon replaced the Delta variant and others, is now the dominant variant worldwide. The emergence of Omicron poses new challenges for the prevention and control of COVID-19 and has raised a number of concerns worldwide. Recently, cases of Omicron infection have been reported in several parts of China, and therefore this paper provides a comprehensive analysis and summary of the epidemiology and immune escape mechanisms of the Omicron variant. We also suggest some therapeutic strategies against the Omicron variant, including rapid diagnosis, genome analysis of emerging variants, ramping up of vaccination drives and receiving booster doses, updating the available vaccines, designing of multivalent vaccines able to generate hybrid immunity, up-gradation of medical facilities and strict implementation of adequate prevention and control measures need to be given high priority to handle the on-going COVID-19 pandemic successfully.

Objective:To explore the factors affecting curative effect of motor imagery brain-computer interface (MI-BCI) training on upper limb paralysis for subacute stroke patients. Methods:From January, 2018 to July, 2019, 23 inpatients with post-stroke upper limb paralysis accepting MI-BCI training were reviewed. The gender, age, course of disease, aphasia, location and nature of lesion, history of Botulinum toxin, hemisphere injured and modified Ashworth Scale (MAS) score of affected fingers were recorded, and they were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE) before and four weeks after MI-BCI training. According to improvement of FMA-UE wrist and hand scores (≥ 2), the patients were divided into effective group (n = 11) and inefficacy group (n = 12). Results:The MAS scores before MI-BCI training (t = 2.677, P < 0.05) and history of botulinum toxin (Z = 0.000, P < 0.05) were more in the inefficacy group than in the efficacy group. FMA-UE scores (total and dimensions) after training were correlated to their baseline levels (r > 0.831, P < 0.01), FMA-UE total scores (Eta = 0.453, P < 0.05) and upper arms scores (Eta = 0.506, P < 0.05) were correlated to aphasia, FMA-UE scores of hands were correlated with MAS (r = -0.521, P < 0.05). Conclusion:Poor baseline motor function, spasticity and complication with aphasia were the factors unfavorable to MI-BCI training for subacute stroke patients with upper limb paralysis.

Objective:To investigate the topological alterations in brain functional networks following comprehensive treatment including brain-computer interface (BCI) training in subacute stroke subjects. Methods:From January, 2018 to June, 2019, 14 subacute stroke patients with moderate to severe upper limbs paralysis accepted routine physical therapy, occupational therapy and BCI training based on motor imagery, for four weeks. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE), Action Research Arm Test (ARAT) and Wolf Motor Function Test (WMFT) before and after treatment, while the functional connectivity (FC) was investigated with resting state functional magnetic resonance imaging. Results:The scores of FMA-UE, ARAT and WMFT increased after treatment (|t| > 5.298, Z = -3.297, P < 0.01). The FC also increased across the whole brain, including temporal, parietal, occipital lobes and subcortical regions. The FC between left piriform cortex of parietal lobule (BA5L) and right medial surface of temporal lobe (BA48R), as well as those between left precentral gyrus (BA4L) and right anterior transverse temporal gyrus (BA41R) (r > 0.416, P < 0.05). Conclusion:Comprehensive rehabilitation including BCI training may promote recovery of motor function and activities of FC in brain in subacute stroke patients.

OBJECTIVETo summarize the clinical characteristics of peripheral blood, immune phenotypes, fusion genes and cytogenetics of patients with t(8;21) acute myeloid leukemia(AML) through the retrospective analysis of 586 patients with t(8;21) AML from 15 blood disease research centers in Northern area of China.

METHODSThe factors affecting prognosis of patients with t(8;21) AML were investigated by using univariate and multivariate COX regression.

RESULTSThe immune type of t(8;21) AML patients was mainly with HLA-DR, CD117, CD34, MPO, CD38, CD13and CD33(>95%), part of them with CD19and CD56; the most common accompanied mutation of t(8;21) AML patients was C-KIT mutation (37.8%); in addition to t(8;21) ectopic, the most common chromosomal abnormality was sex chromosome deletions (38.9%). The univariate analysis revealed a significant survival superiority of OS and PFS in t(8;21) AML patients of WBC≤3.5×10/L without C-KIT mutation, the newly diagnosed ones achieved HSCT(P<0.05), only survival superiority on OS in t(8;21) AML patients with extramedullary infiltration and CD19 positive; the results of multivariate analysis showed a significant survival superiority on OS and PFS in t(8;21) AML patients with WBC≤3.5×10/L(P<0.05).

CONCLUSIONThe clinical features of t(8;21) AML patients in China are similar to those in other countries, WBC≤3.5×10/L is a good prognostic factor while the C-KIT mutation is a poor one in t(8;21) AML patients.
