Objective To analyse the changes of metabolic parameters and condition of metabolic syndrome(MS)in females with obstructive sleep apnea-hypopnea syndrome(OSAHS),and explore the interaction between OSAHS and MS.Methods Sixty females undergoing polysomnography were included,and were divided into simple snorer group(n=19),mild OSAHS group(n=21)and moderate to severe OSAHS group(n=20).Epworth sleepiness scale(ESS)scores and metabolic parameters were compared among groups.Forty-one patients with OSAHS were subdivided into group with MS(MS group,n=15)and group without MS(non-MS group,n=26).ESS scores,apnea hypopnea index(AHI),oxygen desaturation index(ODI)and lowest pulse oxygen saturation(LSpO_2)were compared between MS group and non-MS group.Results There was no significant difference in age,body mass index(BMI),total cholesterol(TC),triglyceride(TG),low density cholesterol(LDL),high density cholesterol(HDL),apolipoprotein A-I(apoA-I)and apolipoprotein B(apoB) among simple snorer group,mild OSAHS group and moderate to severe OSAHS group(P>0.05).Correlation analysis revealed ESS was positively related to AHI(r=0.327,P=0.011).ESS scores and proportions of hypertension,fasting plasma glucose(FPG)and MS were significantly higher in moderate to severe OSAHS group than those in simple snorer group(P<0.05).BMI,FPG,TG,proportion of hypertension,ODI and ESS score in MS group were significantly higher than those in non-MS group(P<0.05),while there was no significant difference in AHI and LspO_2 between these two groups(P>0.05). Conclusion ESS score may reflect the severity of OSAHS in females.Females with OSAHS matched for age and BMI have no difference in blood fat.With the increase of severity of OSAHS,glycometabolism can be impaired,the prevalences of hypertension and MS increase.MS can exacerbate the severity of OSAHS,indicating that MS and OSAHS interact with each other.

OBJECTIVETo analyze the results of postoperative radiotherapy with electronic beam for patients with keloids in our hospital.
METHODSFrom September 2006 to May 2009, radiotherapy was given within 24 hours after operation in 53 keloid patients. With single vertical field irradiation, 6-12 Mev electronic beams of Linear Accelerator were selected for different incision depth in different sites. The field size was 1.0 cm (range: 0.5-2.0 cm) away from both incision ends and 1.25 cm (range: 0.75-2.50 cm) away from incision laterally. The radiation was given daily with median treatment course of 4 days (range: 3-21 days) at 3.5 Gy/Fx to a median total dose of 14 Gy (range: 8-20 Gy). SPSS 21. 0 was used for analysis.
RESULTSAll postoperative incisions healed in one stage, the median follow-up was 34 months (range: 18-63 months). The overall local control rate was 79.7%. For patients who received the dose of more than 14 Gy versus less than 14 Gy, the local control rate was 81.6%, 75.2%, respectively (P > 0.05). For male and female, the 3 year local recurrence rate were 45.3%, 9.9% respectively (P = 0.008). Multivariate analysis showed that the sex (male versus female) was an independent prognostic factor (P = 0.036).
CONCLUSIONSurgery combined with electronic beam irradiation is a rather effective way to treat keloids. The local control rate would have a better trend if the total dose was higher than 14 Gy. Sex is an independent prognostic factor.

Abstract: Objective To investigate the epidemiological characteristics of pathogens causing bloodstream infection in hematology patients during treatment and to compare the effects of allogeneic hematopoietic stem cell transplantation (HSCT) on them, so as to provide evidence for the diagnosis and treatment of bloodstream infection. Methods A total of 292 cases with bloodstream infection in hematology wards of the PLA General Hospital were collected from 2017 to 2021, which were divided into HSCT group and N-HSCT group according to whether performed HSCT or not. The epidemiological characteristics and influence of pathogenic bacteria in blood stream infection were analyzed and compared between the two groups. Results A total of 362 strains of pathogenic bacteria were collected from 292 cases, including 106 strains in HSCT group (84 cases) and 256 strains in N-HSCT group (208 cases). Bloodstream infections were more common in acute myeloid leukemia (130/392, 44.52%), followed by non-Hodgkin's lymphoma (74/292, 25.34%). The rate of once bloodstream infection in HSCT group was higher than that in N-HSCT Group, but the rate of twice bloodstream infections in N-HSCT group was higher. Gram-negative Bacilli were the most common pathogens (56.08%), with Escherichia coli being absolutely dominant (109/362, 30.11%), followed by Klebsiella pneumoniae (39/362, 10.77%). Coagulase-negative staphylococci (CoNS) (107/362, 29.56%) were the most common Gram-positive cocci. The detection rate of fungi in HSCT group (10/106, 9.43%) was significantly higher than that in N-HSCT Group (3.52%). The drug resistance rate of the common pathogenic bacteria was at a high level, and there was a certain proportion of multi-drug resistant strains (except for Pseudomonas aeruginosa). The resistance rates of CoNS to penicillin, gentamicin, moxifloxacin, clindamycin and rifampicin in HSCT group were higher than those in N-HSCT Group. The resistance rate of Escherichia coli to piperacillin/tazobactam, cephalosporins and etapenem in HSCT group was significantly higher than that in N-HSCT group. Conclusions The pathogens of blood stream infection in hematology patients are complicated and various. It is difficult for clinical diagnosis and treatment to detect multiple infections and multiple pathogens. HSCT patients have a higher risk of fungal bloodstream infection and more multi-drug resistant strains detected. Therefore, the identification of bloodstream infection and multi-drug resistant strains associated with HSCT patients should prompt surveillance.

OBJECTIVETo evaluate the long-term effects of arteriovenous fistula (AVF) on heamodynamic changes and cardiac structure and function in non-diabetic hemodialysis patients.
METHODSData were collected from 50 non-diabetic hemodialysis patients (aged 18 to 60 years) who had used AVF as the vascular access. AVF flow (Qa), stoke volume (SV), cardiac output (CO), cardiac index (CI), central blood volume (CBV) and peripheral vascular resistance (PR) were measured using the ultrasound dilution technique. Echocardiography was performed in the second day after hemodialysis sessions to evaluate the influence of AVF on the cardiac structure and function.
RESULTSThe cubic polynomial regression model best fit the relationships of Qa with SV, CO, and CI. CO and CI significantly increased and PR reduced when the Qa of AVF was more than 2.0 L/min(all P<0.05), and no statistical difference of CO, CI and PR in groups of Qa between 0.6-2.0 L/min and less than 0.6 L/min(all P>0.05). In different Qa groups, the grades of cardiac function (based on New York Heart Association classification) showed significant difference, among which the cardiac failure was significantly common when Qa >2.0 L/min(both P<0.05). Echocardiography showed the left atrium dimension, thickness of posterior wall and interventricular seprum of left ventricle, left ventricular end-systolic dimension (LVESD) and end-diastolic dimension (LVEDD), venae cava inferior, and pulmonary artery systolic pressure gradually increased when Qa increased, while the ejection fraction and fractional shortening reduced(all P<0.05). Notably, the changes of LVESD, LVEDD, and venae cava inferior with different Qa were statistically significant(all P<0.05).
CONCLUSIONSLong-term AVF remarkably affects the cardiovascular dynamics of non-diabetic hemodialysis patients. A cubic polynomial regression model best fits the relationship of AVF Qa with SV, CO, and CI. The cardiac adaptic changes after long-term AVF include the enlargement of left ventricle and the thickening of ventricular wall. The risk of cardiac failure significantly increases when the Qa of AVF is more than 2.0 L/min with much higher CO and lower PR.

OBJECTIVETo prospectively determinate the association of left ventricular systolic and diastolic function with intradialytic hypotension (IDH) in patients on maintenance hemodialysis.
METHODSTotally 115 patients with sinus rhythm were included in this study and divided into IDH group (n=29) and control group (n=86). The cardiac function was assessed by New York Heart Association (NYHA) classification before hemodialysis. Echocardiograms were performed in the next day after hemodialysis and the software of GE EchoPAC was used to estimate parameters of cardiac systolic and diastolic functions including ejection fraction, fractional shortening of left ventricular diameter, stroke volume (SV), cardiac output (CO), left ventricular mass index, Tei index, isovolumetric relaxation time, E-deceleration time, mitral inflow peak early diastolic velocity (E) to late diastolic velocities (A) ratio, and E to peak mitral annulus velocity (E/Em) ratio.
RESULTSThe mean age (p=0.045) and the ratio of heart failure evaluated by the NYHA classification (p<0.01) were significantly higher in IDH group than those in control group. No difference was noted for gender, body mass index, duration of dialysis, body weight elevated rate and blood pressure between these two groups (all p>0.05). Left ventricular diameters at the end of diastolic phase, SV, and CO in IDH group were significantly lower than those in control group (all P<0.05), whereas no significant difference was found for EF, FS, Tei index, IVRT, EDT, E/A and E/Em ratio (all p>0.05). Multivariate logistic regression analysis showed that NYHA cardiac function was an independent predictor of IDH, and the risk of IDH increased by 1.134 times with incremental one grade of NYHA classification.
CONCLUSIONSIDH is a common complication of hemodialysis. Neither systolic dysfunction nor diastolic dysfunction of left ventricle evaluated in second day after hemodialysis affects its frequency, whereas the clinical cardiac function is an independent predictor of IDH.

Objective:To compare the clinical and prognostic characteristics of ovarian endometrioid carcinoma (OEC) patients with synchronous endometrial lesions and patients with pure OEC.Methods:A retrospective review of the medical records of patients received initial treatment and a postoperative pathological diagnosis of OEC at Peking University People′s Hospital between August 1998 and December 2017 were performed. According to the inclusion criteria, a total of 56 patients with OEC were included in the study, including 13 patients concurrent with simultaneous endometrial lesions (Group A) and 43 patients with pure OEC (Group B).Results:Patients with synchronous endometrial lesions accounted for 23% (13/56). Mean age of Group A at diagnosis was (44.9±8.3) years old, 2/13 of patients were postmenopausal, and no one had a history of hypertension, the first symptom of 5/13 people was irregular vaginal bleeding. Mean age of Group B patients at diagnosis was (52.7±10.2) years old, 53% (23/43) of patients were postmenopausal, and 28% (12/43) patients had the history of hypertension, the first symptom of 4 (9%, 4/43) people was irregular vaginal bleeding. The differences of age, menopause status, history of hypertension and initial symptoms between the two groups were statistically significant (all P<0.05). There were no significant differences in fertility history, dysmenorrhea history, age of menarche, history of endometriosis, preoperative and postoperative CA 125 level, International Federation of Gynecology and Obstetrics (FIGO) stage, tumor grade, metastatic site and platinum-based chemotherapy drug resistance between the two groups (all P>0.05). The overall 5-year survival rate of OEC patients was 91.6%, and the overall 5-year progression-free survival rate was 76.6%. Among them, the 5-year survival rate of the OEC concurrent with simultaneous endometrial lesions group was 80.2%, and the pure OEC group was 93.4%; the 5-year progression-free survival rate of the OEC concurrent with simultaneous endometrial lesions group was 74.1%, and the 5-year progression-free survival rate of the pure OEC group was 77.3%. There were no significant differences between the two groups (all P>0.05). Multivariate analysis showed that the independent factors for the prognosis of OEC patients were FIGO stage ( P=0.006) and residual lesion size ( P=0.020). Conclusions:OEC patients have a high proportion of simultaneous endometrial lesions. OEC with simultaneous endometrial lesions are younger than patients with pure OEC. Synchronous endometrial lesions do not affect the prognosis of patients with OEC.

OBJECTIVETo investigate the effect of the total saponin of Panax ginseng (TSPG) on gene expression profile of K562 cells using microarray technique.
METHODSThe total RNA were extracted and purified from K562 cells treated by 200 microg/ml TSPG for 3 days, and untreated K562 cells cultured in parallel served as the control. cRNAs were synthesized and labeled with Cy3 and Cy5 respectively. The labeled cRNA fragments were hybridized with Agilent human 1B 60 mer oligonucleotide microarray, which was then scanned to reveal the changes of gene expression profile in relation to TSPG treatment.
RESULTSTotally 362 differentially expressed genes were identified in TSPG-treated K562 cells, including 20 up-regulated ones (consisting of metabolism-associated genes, signal transduction-associated genes and cell receptor-associated genes etc) and 342 down-regulated ones (consisting of immunity and defense-associated genes, DNA-binding and transcription genes, metabolism-associated genes and cell cycle-associated genes etc). Changes in expressions of FOSL1, E2F2, CCNE2 and ODZ1 were confirmed by semi-quantitative RT-PCR.
CONCLUSIONSTSPG may induce changes in the gene expression profile in k562 cells possibly relevant to the anti-tumor mechanism of TSPG.
