Objective: To detect the systolic and diastolic velocity in patients with idiopathic premature ventricular beat(PVB)by pulsed wave-tissue Doppler imaging (PW-TDI) techniques.Methods: There were two groups involved in this study. PVB group,n=30,patients with idiopathic PVB,and Control group,n=30,of healthy subjects. The changes of cardiac function were measured and compared between two groups by the index of myocardial motion velocity using PW-TDI techniques.Results: A total of 7 sites were studied,there were no significant differences in systolic peak velocities (Sm),time velocity integral (TVI),peak velocity of the early relaxation wave (Em),peak velocity of the later relaxation wave (Am) and Em/Am ratio (Em/Am) between the Control group and PVB group in the normal sinus beat (P＞0.05).Compared with the normal sinus beat,Sm,TVI,Em and Em/Am were significantly lower in PVB (P<0.01),while Sm,TVI,Em in the post-PVB sinus beat were significantly higher than that in normal sinus beat (P<0.01). However,there were no significant differences of Am in each site among the normal sinus beat,PVB and the post-PVB sinus beat. Conclusion: PVB and PVB-induced compensational interval could significantly influence the systolic and diastolic function of the ventricle.

OBJECTIVETo establish a method for rapid detection and sub-typing of human papilloma virus (HPV).

METHODSWe utilized the piezoelectric genosensor (PG) technique, which is a combination of the piezoelectric biosensor and gene chips for HPV identification in 22 recurrent biopsy specimens and 22 corresponding original biopsy specimens. The control samples came from normal tissue of healthy persons. A combined reaction took place on the sensor surface between the target genes and probes. The frequency of the piezoelectric sensor will decrease when such reactions occur, and the frequency decrease depends on the concentration of the target gene. Specimens were also analyzed with conventional PCR and dot blot.

RESULTSOf the 22 recurrent specimens, 15 contained HPV6 DNA, 2 HPV11 DNA, and 4 HPV16 DNA. Only one specimen was negative. All the 22 original specimens were positive: 17 harbored HPV6 DNA, 3 sequence homologous HPV11 DNA, and 2 HPV16 DNA. No HPV18 DNA was detected in any specimen. When compared with PCR and dot blot analysis, the results were essentially the same except for one specimen, which was shown to contain other sub-types of HPV.

CONCLUSIONOur results show that the piezoelectric genosensor technique is a rapid and specific method to analyze HPV.

Objectives　To investigate the efficacy of accelerating hemopoietic reconstraction and reducing a graft versus host disease (GVHD) in Allo-BMT receiving lenograstim stimulated donor marrow and to assess the preliminary biological mechanism . Methods　The donors for thirty patients (study group) with leukemia were given lenograstim 3-4?μg*kg-1*d-1 for seven days prior to marrow harvest. The results of subsequent engraftment in the recipients was compared with fifteen donors without G-CSF (control group). Five donors themselves were studied to assess the effects of lenograstion on hematopoietic progenitor cells and lymphocyte subsets in BM. Results　The stimulated bone marrow contained a higher number of nucleated cells, CFU-GM and CD34+ cells (P<0.01). The hematopoetic reconstitution was accelerated. Until granulocyte counts exceeded 0.5×109/L and plalete counts exceeded 20×109/L, the days were 16.7±3.2 and 18.4±3.0 days as compared with those of the control group (22.5±5.1 and 26.3±5.9 days respectively, P<0.01). The incidence of grade Ⅱ-Ⅳ aGVHD was very low, only one case with grade Ⅱ aGVHD on the skin in the study group. Four out of fifteen patients (26.7%) in the control group had grade Ⅱ-Ⅳ aGVHD (P<0.05). The number of T lymphocyte subsets in the harvested BM stimulated by G-CSF changed. In comparison with the control group, CD4+ decreased and CD8+ increased significantly (P<0.01). The changes of progenitor cells and T lymphocyte subsets in BM from pre- to post- G-CSF stimulation indicated that the percentage of CD4+ cells reduced (P<0.05), that of CD8+ cells, and that of CD34+ increased (P<0.01). The incidence of chronic GVHD and relapse of leukemia were not different significantly between both groups. Conclusions　Allogenic bone marrow transplant (Allo-BMT) donors given G-CSF can accelerate engraftment and minimize the incidence of severe aGVHD. There is a trend in favour of improved transplant-related complicatians.

Objective:Analysis of the characteristics of influenza epidemic in Anhui Province and quantification of the impact of different factors on influenza occurrence, providing scientific basis for better influenza prevention and control.Methods:Descriptive analysis and factor analysis were conducted on influenza-like illness (ILI) cases and RT-PCR results in Anhui Province from 2013 to 2021 using data from China's Influenza Monitoring Information System.Results:The percentage of influenza-like illness (ILI%) of sentinel hospitals in Anhui Province from April 1, 2013 to March 31, 2021 was 3.80% (1 209 142/31 779 987), showing an overall increasing trend, with a relatively high proportion in 2017-2018 at 4.30% (191 148/4 448 211). The proportion of ILI cases in infants and young children aged 0-4 years was a relatively high at 54.14% (654 676/1 209 142), and the highest ILI% was observed in Fuyang City, Anhui Province (6.25%, 236 863/3 788 863). Laboratory monitoring results showed that the positive rate of ILI cases in sentinel hospitals in 8 influenza monitoring years was 16.38% (34 868/212 912), showing an increasing trend year by year, with a relatively proportion in 2017-2018 at 26.19% (6 936/26 488). The detection rate of school-age children aged 5-14 years was a relativelyhigh at 28.81% (13 869/48 144), and the positive rate was a relatively high in Wuhu City among the 16 cities, reaching 22.01% (2 693/122 237). Influenza activity showed a single peak in winter-spring and alternating double peaks in winter-spring and summer, with different subtypes alternating, and A (H3N2) was the dominant subtype in summer. The results of a multiple logistic regression model showed that the positive rate was higher in 2017-2018, among children aged 5-14 years, in winter, and in southern Anhui.Conclusions:Influenza epidemic in Anhui Province has a clear seasonal pattern, and the ILI% and detection rate have shown an upward trend from 2013 to 2021. Therefore, it is suggested to ensure vaccine supply before the winter-spring influenza season arrives, and to strengthen vaccine uptake and health education to avoid the risk of infection during the peak period of influenza.

Objectives:To observe the exercise tolerance and cardiopulmonary function characteristics of patients with obstructive sleep apnea-hypopnea syndrome (OSAHS) combined with cardiovascular disease,in order to assess the cardiorespiratory reserve and health status of untreated OSAHS,and to provide a clinical evidence for the phase Ⅱ cardiac rehabilitation. Methods:This retrospective analysis included 134 cardiovascular disease patients who attended the Cardiac Rehabilitation Center of Fuwai Hospital,Chinese Academy of Medical Sciences from November 2021 to April 2024 and received home sleep apnea monitoring (HSAT).According to the apnea hypopnea index (AHI),the patients were divided into the non-OSAHS (AHI<5 times/h) group (n=24),the mild-OSAHS (5 times/h ≤AHI<15 times/h) group (n=65),and moderate-to-severe OSAHS (AHI ≥15 times/h) group (n=45),and the body composition,pulmonary function characteristics,exercise tolerance,and ventilatory response to exercise were compared among the three groups. Results:A total of 110 (82.1％) patients had comorbid OSAHS,with a higher proportion of male patients (80.0％).Height,weight,body mass index,lean body mass,skeletal muscle mass,body water content,and basal metabolic rate increased progressively with increasing OSAHS severity in three groups (all P<0.05),while cardiovascular disease comorbidity was similar.Static lung function,exercise tolerance and ventilatory function at maximal exercise were similar between the patients in the mild OSAHS group and the moderate-severe OSAHS group as compared to the non-OSAHS group (all P>0.05).With the increase in the severity of OSAHS,the cardiorespiratory fitness showed a decreasing trend among patients in the three groups,and the forced vital capacity and the maximum vital capacity of patients in the moderate-severe OSAHS group were significantly higher than that of the mild OSAHS group,while peak O2 pulse％pred was significantly lower than that of the mild OSAHS group (all P<0.05).Multivariate analysis showed that the body fat mass (β=0.307,95％CI:0.263-0.823,P<0.001),minute ventilation at rest (β=0.259,95％CI:0.429-1.785,P=0.002) were the independent influencing factors of AHI. Conclusions:The prevalence of OSAHS is high in patients with cardiovascular disease,and patients with moderate-to-severe OSAHS have reduced cardiorespiratory fitness,OSAHS is not associated with additional cardiac impairment and ventilatory function impairment in patients with cardiovascular disease.Weight loss should be the primary rehabilitation goal in patients with OSAHS combined with cardiovascular disease.

Objective To study the clinical and CT findings of bronchiolar adenoma. Methods Patients diagnosed with bronchiolar adenoma confirmed by surgical pathology at Linyi People's Hospital and Yantai Yuhuangding Hospital from 2016 to 2021 were collected. Their clinical and CT imaging features were retrospectively analyzed. Results Finally, 25 patients were collected, including 6 males and 19 females, aged 32-73 (58.6±10.1) years. The immunohistochemical Ki-67 (MIB1) of all lesions was <5%. The lesions were located in the upper and middle lobe of both lungs in 9 patients, lower lobes in 16 patients, extrapulmonary zone in 22 patients, intrapulmonary middle zone in 3 patients, round in 11 patients, irregular in 14 patients, well-defined in 22 patients, pure ground-glass/mixed ground-glass nodules in 6 patients, solid nodules in 19 patients. There were 11 patients with central small cavity, 18 patients with single bronchioles sign, 19 patients without adhesion with adjacent pleura, and 24 patients without mediastinal lymph node enlargement. Conclusion Bronchiolar adenomas usually occur in the middle-aged and elderly, mostly in the lower lobe of both lungs and the distribution of the peripheral lung field, most of the patients do not have any clinical symptoms, and the postoperative prognosis is good. CT may show large nodules or masses, pure ground-glass/mixed ground-glass nodules, irregular solid nodules and central small cavities. Irregular stellate nodules, central small cavity shadow, and single bronchiolar vascular bundle connected with the lesions are relatively specific imaging findings of bronchiolar adenoma.
