OBJECTIVETo observe the effect of resting heart rate (RHR) on the progression to hypertension in patients with prehypertension.
METHODSPeople who participated the physical examination between 2006 and 2007 at Kailuan medical group and diagnosed as prehypentension were selected as the observation cohort. The second and the third physical examination were conducted between 2008 and 2009 and between 2010 and 2011. The observation population was divided into five groups according to the different levels of RHR at baseline: the first group ( ≤69 beats/min), the second group (70-74 beats/min), the third group (75-79 beats/min), the fourth group (80-84 beats/min) and the fifth group ( ≥85 beats/min). The rate of the progression to hypertension was compared among five groups, and the relationship between RHR and the progression to hypertension was estimated using Cox proportional hazard analysis.
RESULTSA total of 34 512 patients with prehypentension were recruited and 25 392 patients were involved in the final statistics after excluding patients who died or were lost to follow-up. A total of 13 228 (52.1%) patients with prehypentension developed hypertension during follow-up. The rate of the progression to hypertension increased with the RHR (first group: 51.2%, second group: 50.1%, third group: 52.9%, fourth group: 53.5%, fifth group: 57.5%). Multiple Cox regression models showed that the risk of the progression to hypertension increased with the RHR levels. Patients in the fifth group carried 1.25 times higher risk for developing hypertension than patients in the second group after adjustment for age, gender, systolic blood pressure, diastolic blood pressure, waist circumference, body mass index, triglyceride, total cholesterol, low density lipoprotein cholesterol, high density lipoprotein cholesterol, fasting blood glucose, serum uric acid, C-reactive protein, smoking, drinking, physical exercise and family history of hypertension at baseline.
CONCLUSIONElevated RHR is an independent risk factor for the progression to hypertension in patients with prehypertension.

OBJECTIVETo conduct a systematic review of the safety and efficacy of enhanced recovery after surgery(ERAS) program in perioperative management of pancreaticoduodenectomy.
METHODSA computerized search was performed in databases including PubMed, Embase, Medline, Web of Science, Cochrane Library, CNKI, Wanfang and VIP for randomized controlled trials (RCTs) or clinical controlled trials (CCTs) describing an ERAS program in patients undergoing pancreaticoduodenectomy published between January 1966 and May 2014. After assessment of methodological quality and data extraction, meta-analysis was performed using RevMan 5.2.0 software.
RESULTSSix RCTs and 8 CCTs including 2565 patients were selected for this study, including the study group(n=1366) and the control group (n=1199). Compared with the control group, the study group had a shorter length of hospital stay(WMD=-3.67, 95% CI:-5.66--1.68, P<0.05), lower postoperative complication rate(OR=0.73, 95% CI:0.56-0.95, P<0.05) and lower mortality(OR=0.63, 95% CI:0.44-0.91, P<0.05). However, no significant differences existed in mortality, readmission rate and re-operation rate between the two groups.
CONCLUSIONSEnhanced recovery after surgery programme in perioperative management of pancreaticoduodenectomy is safe and effective. But due to the medium quality of the literature. This still need more rigorously designed RCTs to prove the safety and efficiency of ERAS programme for the patients undergoing pancreaticoduodenectomy.

OBJECTIVETo investigate the correlation between long time systolic blood pressure variability(SBPV)and short time SBPV in aged population.
METHODSA total of 752 subjects aged ≥60 years of Kailuan Group who took part in 2006-2007, 2008-2009, 2010-2011 and 2012-2013 health examination were included by cluster sampling method.Long time SBPV was calculated by standard deviation of mean systolic blood pressure measured in 2006-2007, 2008-2009, 2010-2011 and 2012-2013, standard deviation represents short time systolic blood pressure which is derived from 24 hour ambulatory blood pressure monitoring. The observation population was divided into three groups according to the third tertiles of the time systolic blood pressure variability: the first point(<9.09 mmHg (1 mmHg=0.133 kPa)), second point (≥9.09 mmHg, and <14.29 mmHg), and third point (≥14.29 mmHg). Multivariate logistic regression analysis was used to analyze the correlation between long time systolic blood pressure variability and short time systolic blood pressure.
RESULTS(1) The participants' age were (67.0±5.7) years old (284 women). (2) The 24 hours and daytime SSD were (14.7±4.0) mmHg, (14.7±3.5) mmHg, (15.7±4.4) mmHg (P=0.010) and (14.1±4.4) mmHg, (14.2±3.5) mmHg and (15.4±4.6) mmHg (P<0.001) according to the tertiles of long time systolic blood pressure variability, respectively, nighttime SSD were (12.0±4.4) mmHg, (11.8±4.8) mmHg and (11.9±4.9) mmHg (P=0.900). (3) Multiple logistic regression analysis showed that the tertiles of long time SSD was the risk factor for increasing daytime SSD>14.00 mmHg (OR=1.51, 95%CI: 1.03-2.23, P=0.037), but not a risk factor for increasing 24 hours SSD>14.41 mmHg (OR=1.10, 95%CI: 0.75-1.61, P=0.639) and nighttime SSD>11.11 mmHg (OR=0.98, 95%CI: 0.67-1.42, P=0.899).
CONCLUSIONIncreased long time SBPV is a risk factor for increasing daytime SBPV.

Objective To investigate the impact of different levels of systolic blood pressure on brachial-ankle pulse wave velocity(baPWV). Methods A total of 5 852 participants was selected with stratified random sampling from the 101 510 workers of Tangshan Kaiuan Company who had undergone a physical check-up program. 5 222 of them with integral data were recruited into this survey. According to SBP collected during the 2010-2011 health examination program,the population under observation was divided into four groups:optimal SBP(SBP<120 mmHg),high-normal blood pressure Ⅰ period(120 mmHg≤SBP<130 mmHg),high-normal blood pressure Ⅱ period (130 mmHg≤SBP<140 mmHg)and hypertension(SBP≥140 mmHg or SBP<140 mmHg but antihypertensive drug user). Multivariate logistic regression analysis was used to analyze the influence of different levels of systolic blood pressure on baPWV. Results 1)There were 3 132 males and 2 090 females in all the 5 222 participants with an average age of 55.1 years old. Their mean of baPWV was(1 587.57±400.71)cm/s,with the detection rates as 62%(baPWV≥1 400 cm/s). 2)The means of baPWV for the above groups of SBP were 1 322.19,1 456.27,1 544.78 and 1 827.77 cm/s, respectively,with detection rates of baPWV≥1 400 cm/s as 26.4%,49.3%,64.2% and 88.3%, respectively. 3)Results from the Multiple linear regression analysis revealed that β of SBP was 0.40,only ranking second,on age(0.48). 4)Data from the Multiple logistic regression analysis showed that after adjusting for age,gender and other risk factors,when compared to optimal SBP,factors as high-normal blood pressure Ⅰ period、high-normal blood pressure Ⅱ period and hypertension were risk factors for increasing baPWV,with OR values as 2.70(95%CI:2.20-3.32),4.56(95%CI:3.67-5.67)and 13.51(95%CI:10.87-16.78),respectively. Conclusion Higher SBP seemed an independent risk factor for the increase of baPWV.

Objective:To explore ultrasonographic diagnostic characteristics of ovarian epithelial tumors and establish prediction models.Methods:The ultrasonographic images of 427 cases from multicenter with ovarian epithelial tumors confirmed by pathology from January 2015 to July 2019 were retrospectively analyzed according to the International Ovarian Tumor Analysis (IOTA). Ultrasonographic signs with distinguishing significance were obtained through univariate analysis and included into multivariate Logistic regression analysis to obtain important ultrasonagraphic indicators for distinguishing borderline, benign and malignant ovarian tumors, and to establish prediction models.Results:The microcystic pattern of papillary projections and solid components was the diagnostic characteristic between borderline and benign, malignant ovarian epithelial tumors( OR value 10.97 and 19.22, respectively). Irregular morphology, septa thickness, solid lesions, rich blood supply and ascites were diagnostic characteristics between benign and malignant tumors, with the irregular morphology having the highest value. Irregular morphology, large papillary, septa thickness and rich blood supply could be used to identify borderline and malignant tumors. At the same time, irregular morphology was the valuable sign to distinguish borderline and benign tumors. In this study, the total coincidence rate of the proposed model was 72.4%, among which the predicted coincidence rate of the borderline model was 57.2%, 78.6% for benign, and 80.7% for malignant. Conclusions:The microcystic pattern of papillary projections and solid components are the specific sonographic characteristics of borderline ovarian tumors. Irregularity, solid lesions, rich blood supply and ascites have important value in differentiating ovarian epithelial tumors. The prediction models of benign, malignant and borderline ovarian tumors in this study have higher diagnostic efficacy.

Objective:To explore the relationship between the changes of anorectal angle (ARA) under 3 physiological states and pelvic organ prolapse(POP) in postpartum women by transperineal ultrasound.Methods:The retrospective study enrolled 147 female in 6-8 weeks after delivery examined by pelvic floor ultrasound examinations in Fujian Medical University Second Affiliated Hospital from November 2019 to June 2021, who were divided into POP group and control group. Volume data of pelvic floor ultrasound examinations were obtained at rest, during contraction and during maximal Valsalva maneuver. The differences in the changes of ARA under 3 physiological states between the two groups were compared, and the correlation between the change state of ARA during maximal Valsalva maneuver and POP was analyzed.Results:Compared with ARA at rest, ARA decreased during contraction (χ 2=42.64, P<0.001) and increased during maximal Valsalva maneuver (χ 2=38.43, P<0.001). There was no difference of ARA between the POP group and control group in the 3 physiological states ( P>0.05). However, the risk of POP increased when ARA decreased during maximal Valsalva maneuver ( OR=2.690, 95% CI=1.074-6.739, P<0.05). Conclusions:The decrease of ARA during maximal Valsalva maneuver may increase the risk of POP, and the change of ARA during maximal Valsalva maneuver can be brought into the ultrasonic observation indicators of POP.

Objective:To understand the current situation and problems in the construction of research wards in Beijing municipal hospitals, and put forward corresponding strategies and suggestions to explore the path for the construction of research hospitals.Methods:From March 2020 to May 2021, through the method of questionnaire and expert interview, the bed and personnel allocation, projects undertaken, review efficiency and problems faced by the research wards of 22 Beijing municipal hospitals were analyzed in depth.Results:82%(18/22)of the municipal hospitals explored the construction of research wards, and 27%(6/22) were Beijing Demonstration research wards construction units. In 2020, the overall performance of the construction of research ward was as follows: the investment of clinical research resources was increased, the ability of clinical research was enhanced, the ability to serve enterprises in Beijing was improved, the efficiency of examination was improved, but the enrollment rate of clinical research(including clinical trials) was reduced. At present, the main problems were focused on investment, personnel and informatization.Conclusions:The construction of research wards in Beijing municipal hospitals is developing steadily, but there are still some problems, such as lack of clinical research talents, performance incentive and guarantee to be strengthened. In the future, we should strengthen the training of clinical research talents, improve the incentive and guarantee mechanism, promote the integration of industry, university and research, accelerate the construction of clinical research information system, further improve the hospital′s clinical research ability and level, and accumulate experience for the construction of research hospitals.

OBJECTIVETo compare the prevalence of hypertension between low birth weight infant (LBWI) women and non-LBWI women.
METHODSA retrospective cohort study was applied and 3 172 pregnant women giving births during October 1976 to December 2008 in our hospital and underwent physical check-up between 2010 and 2011 at the Kailuan medical group were included and divided into LBWI group and non-LBWI group by the history of LBWI. Prevalence of hypertension was obtained during the follow-up program. Multiple logistic regression analysis was used to assess the relative risk of hypertension.
RESULTSA total number of 3 172 women, with an average age of 42.3 years old were divided into LBWI group (n = 147) and non-LBWI group (n = 3 025), with the average birth weights of their infants were 2.31 kg and 3.39 kg, respectively. The prevalence of hypertension from the follow-up program was significantly higher in LBWI group than that in the non-LBWI group (23.8% vs. 16.9%, P < 0.05). After adjustment for other traditional risk factors, the risk of hypertension in LBWI group was 1.60 (95%CI:1.02-2.53) folds higher than that in the non-LBWI group.
CONCLUSIONPrevalence of hypertension in women with LBWI was higher than that in those women without LBWI. History of LBWI seemed to have had an increased risk to develop hypertension.
