Objective To investigate the clinical value of serum VEGF levels in the diagnosis and treatment of colon cancer.Methods Serum VEGF was detected by ELISA,and CEA and CA199 concentration were detected by CLEIA in 66 patients with colon cancer,55 patients with colon benign diseases and 50 health persons.The value of individual and joint detection for VEGF in colon cancer was evaluated.Analysis had been done on relationships between serum VEGF and pathology,treatment effects and prognosis.Results The levels of serum VEGF in colon cancer group [(318.5±148.6) ng/L] were significantly higher than those in control group [(125.7±49.4) ng/L] and benign colon diseases [(136.9±52.6) ng/L] (t =8.830,8.805,all P < 0.01).There was a positive correlation between serum levels of VEGF and depth of tumor size,tumor invasion,lymph node metastasis and TNM stage (P < 0.01).The susceptibilities of VEGF,CEA,CA199 were 61%,45 %,53 %.The sensitivity of detection was improved to 86 % when the combined detection of VEGF,CEA and CA199 (x2 =11.237,P < 0.01).The serum levels of VEGF in patients with colon cancer was significantly decreased after treatment in the 3,7,10 day compared with that before operation [(272.3±88.1),(236.8±77.4),(173.1±59.9) vs (318.5±148.6) ng/L,t=2.173,P < 0.05; t =3.961,P < 0.01; t=7.464,P < 0.01],respectively.Conclusion The VEGF was related to the onset and progression and metastasis of colon cancer.It has clinical significancy for diagnosis of colon cancer and judgment of curative effect and prognosis.

OBJECTIVETo investigate the prevalence of hyposexuality, erectile dysfunction (ED) and defective ejaculation (DE) in the old and middle-aged males in Pingliang area.
METHODSThis investigation included 1 539 men aged > or = 50 years from 6 urban districts and 20 villages in the suburbs of Pingliang City, Gansu Province. We recorded and analyzed their scores on IIEF-5 and Brief Male Sexual Function Inventory for Urology (O'Leary 1995).
RESULTSA total of 1 230 subjects met the investigation criteria. They averaged 62.5 +/- 9.6 years of age (range 50-89 years), and were divided into four age groups: 50-59, 60-69, 70-79 and > or = 80 years. The mean scores on IIEF-5 were 0-25 (9.4 +/- 8.6), sexual desire 0-8 (2.3 +/- 2.1), and ejaculation 0-8 (3.6 +/- 3.0). Hyposexuality, ED and DE were defined as sexual desire score < or = 2, IIEF-5 score = 0-21, and ejaculation score < or = 2, respectively. Based on these criteria, the incidence rates of hyposexuality, ED and DE were 57.96%, 92.27% and 36.91%, respectively, with statistically significant differences among different age groups (P < 0.01).
CONCLUSIONThe prevalence of ED, hyposexuality and DE, particularly the incidence of ED, is positively correlated with the increase of age in the old and middle-aged males in Pingliang area.

Objective To determine the independent risk factors for sepsis in patients with large area burns.Methods The study enrolled 307 patients with large area burns treated from June 2014 to June 2015.Related variables included age,gender,visit time,emergency eschar open,burn index,tangential excision of eschar during shock stage,delayed resuscitation during shock stage,oxygen pressure(PaO2),carbon dioxide pressure (PaCO2),assisted ventilation mode,mechanical ventilation time,inhalation injury,prophylactic tracheotomy,continuous lactic acid rise,refractory hypernatremia,heart-lung disease history,and diabetes history.Correlation of the variables with the incidence of sepsis was observed.Independent predictors of sepsis in patients with large burns were differentiated using the Logistic regression analysis.Results Delayed resuscitation during shock period (OR =1.747,95% CI 1.822-7.431,P < 0.05),continuous lactic acid rise (OR =1.758,95% CI 1.137-4.002,P < 0.05),refractory hypernatremia (OR =2.985,95% CI 1.074-6.782,P < 0.05),moderate and severe inhalation injury(OR =14.764,95% CI 0.892-47.323,P < 0.05) and burn index (OR =5.017,95% CI 1.075-23.572,P < 0.05) were found be independently associated with sepsis in patients with large burns.Conclusions These independent risk factors for sepsis in large area burn patients deserve more attention.Early and timely treatment measures may reduce the incidence of sepsis.

OBJECTIVETo investigate the prevalence of benign prostatic hyperplasia (BPH) in Pingliang City of Gansu Province.
METHODSWe performed a cross-sectional randomized study of 836 men aged > or = 40 years from 26 communities of Pingliang, obtained their IPSS, measured the prostate volume by transabdominal ultrasonography, recorded the maximum flow (Qmax) by uroflowmetry, and processed the data by one-way analysis of variance.
RESULTSTotally 820 subjects meeting the study criteria were included in the investigation. The men ranged in age from 40 to 83 years, averaging 61.5 years. The mean IPSS, prostate volume and Qmax were 9.3 +/- 7.8, (29.2 +/- 18.6) ml and (15.3 +/- 7.2) ml/s, respectively, all correlated with age. The prevalence of moderate-severe lower urinary tract symptoms (LUTS) was 46.8% (384/820). The prostate volume was > 20 ml in 63.5% (521/820), and Qmax <15 ml/s in 48.5% (398/805) of the subjects. The incidence rate of BPH, defined as IPSS >7, Qmax <15 ml/s and prostate volume > 20 ml, was 23.5% (193/820).
CONCLUSIONAmong the men aged > or = 40 years in Pingliang, LUTS and prostate volume were correlated positively, while Qmax negatively with age, and the prevalence of BPH was 23.5%.

Objective:To study the effect of blood volume feedback control system on improving intradialytic-hypotension (IDH) in maintenance hemodialysis (MHD) patients.Methods:It was a prospective cohort study. Thirty MHD patients with recurrent IDH in the Dialysis Center of the First Affiliated Hospital of Zhejiang University School of Medicine from March 2021 to March 2022 were selected. A self-control study was conducted in MHD patients. The patients were treated with routine hemodialysis in both baseline phase (A1) and reversal phase (A2), while with hemodialysis under the blood volume feedback control system in intervention phase (B). Each phase lasted for 4 weeks (12 hemodialysis sessions). The average occurrences of IDH and IDH-related adverse events (IDH-RAE, stopping dehydration for more than 10 minutes or getting off the hemodialysis machine 10 minutes earlier due to IDH) of each patient between phase A1, B, and A2 were calculated and compared. In a total of 1 080 dialysis records, a logistic regression analysis model was established with age, sex and intervention as independent variables and with the occurrence of IDH-RAE as the outcome.Results:A total of 30 eligible patients were included in the study, including 14 males (46.7%) and 16 females (53.3%), aged 63.0 (56.5, 72.5) years old, with a median dialysis age of 84.0 (37.2, 120.0) months. The average times of IDH in 30 MHD patients decreased from 1.17 (0.83, 1.67) in stage A1 (before intervention) to 0.33 (0.25, 0.58) in stage B (after intervention) ( P<0.05). The frequency of IDH-RAE decreased significantly from 0.29 (0.19, 0.47) in stage A1 to 0.17 (0,0.25) in stage B ( P<0.05). Logistic regression analysis results indicated that the use of blood volume feedback control system reduced the risk of IDH-RAE by 53% ( OR=0.47, 95% CI 0.34-0.64, P<0.001). Conclusions:The application of blood volume feedback control system can effectively reduce the occurrences of IDH and the risk of IDH-RAE in MHD patients.

Objective:
To investigate the current status and influence factors of HBV intrauterine transmission (BIT) in HBsAg-positive parturients and understand the outcome of HBV transmission and response to hepatitis B vaccine immunization in children in Xi’an.
Methods:
An epidemiological survey was conducted in 341 HBsAg-positive parturients who gave birth in Northwest Women and Children Hospital of Shaanxi Province from January 2015 to January 2018. Serological tests were performed by using venous blood from 344 newborns within 24 hours after birth and at the age of 1 year old. A nested case-control study was conducted to analyze the infection rates of intrauterine dominate HBV infection (DBI) and intrauterine occult HBV infection (OBI) in BIT and their influencing factors in newborns. The epidemiological survey was conducted to collect the information about the outcome of HBV transmission and the positive rate of HBsAb in children at high-risk from August 2016 to October 2018.
Results:
The BIT rate was 46.51
