Objective To study the effect of the deferoxamine mesylate on the prognosis of patients with intracerebral hemorrhage(ICH) after one year. Methods From February 2013 to May 2014,spontaneous ICH patients diagnosed by computed tomography ( CT ) within 18 hours of onset in Mancheng District Hospital of Baoding were evaluated. Patients were randomly divided into experimental group and control group. The treatment of the two groups was similar except that the experimental group received deferoxamine mesylate. Patients were e?valuated by CT and neurology scale( NIHSS scale,GCS scale) at the time of admission and followed up for the first year by the RANKIN( mRS) scale. All clinical data of the two groups were compared. Results Forty?two patients were included in the study, including 21 cases in the experimental group and 21 cases in the control group,there was no significant difference in baseline data between the two groups at admission. There were 6 pa?tients with mRS ≥3 in the experimental group, and 6 patients with mRS ≥3 in the control group after one year. There was no statistically significant difference in the distribution of mRS score between the two groups after one year admission( P=1. 000) . Conclusion There may be no helpful on the prognosis of patients with intrace?rebral hemorrhage by intravenous infusion of deferoxamine mesylate,the further study is needed.

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.

Objective To observe the effects of different levels of sodium arsenite ( NaAsO2) on mRNA expression of pigment epithelium-derived factor (PEDF) and apoptosis-related factors in PC12 cells ( rat neuron properties pheochromocytoma). Methods PC12 cells were treated with different levels of NaAsO2 [0 (control group), 2, 5, 10 μmol/L] for 24 hours. The mRNA expression of PEDF and apoptosis-related factors (Bax, Bcl-2) were detected by real-time quantitative PCR. Results There were significant differences in the mRNA expressions of PEDF between the 4 groups (F=102.28, P<0.05), the mRNA expressions of PEDF in the group of 2, 5, 10μmol/L (0.70 ± 0.07, 0.33 ± 0.04, 0.23 ± 0.10) was lower than that of control group (1.15 ± 0.11, P< 0.05); there were no significant differences in the mRNA expressions of Bax between the 4 groups (0, 2, 5, 10 μmol/L groups: 0.95 ± 0.12, 0.80 ± 0.11, 0.88 ± 0.11, 1.01 ± 0.11, F= 2.01, P> 0.05); there were significant differences in the mRNA expressions of Bcl-2 between the 4 groups (F=19.87, P<0.05), the mRNA expressions of Bcl-2 in the group of 2, 5, 10 μmol/L (0.65 ± 0.03, 0.49 ± 0.04, 0.57 ± 0.09) were lower than that of control group (0.95 ± 0.11, all P<0.05);there were significant differences in the mRNA expressions of Bax/Bcl-2 between the 4 groups (F=8.352, P<0.05), the mRNA expressions of in the group of 5, 10μmol/L (1.80 ± 0.72, 1.82 ± 0.36) were higher than that of control group (1.02 ± 0.24, all P<0.05). Conclusion NaAsO2 may increase the expression of apoptosis-related factorsBax/Bcl-2 mRNA by decreasing the expression of PEDF mRNA in PC12 cells, leading to apoptosis in PC12 cells.

Objective To evaluate the safety and efficiency of robot assisted surgery guided by damage control orthopaedics(DCO) in polytraumatised patients with pelvic ring injuries.Methods A retrospective review of the pelvic fracture database was performed.Twenty-six patients who had sustained a pelvic fracture from September 2012 to December 2015 were suitable for robot-assisted minimally invasive internal fixation.They were 17 men and 9 women,aged from 23 to 58 years (average,42.6 years).Their Injury Severity Score(ISS) ranged from 20 to 31 points (average,21.3 years).According to Tile classification,6 cases were type B2,3 type B3,9 type C2 and 8 type C3.Guided by DCO,the vital signs were stabilized by all means and the fractures treated by simple and temporary external fixation before the pelvic and other fractures were managed by the robot-assisted minimally invasive internal fixation.Demographics,times to operating room (TOR),time from acute stabilization to late definitive internal fixation (TAL),time for bone union,type of robot-assisted surgery for major fractures,length of stay (LOS),postoperative complications and mortality were recorded.The outcomes of the pelvis were evaluated at the final follow-up according to the Matta criteria.Results Of the 26 patients,robot-navigated percutaneous screwing was conducted with 23 sacroiliac screws in 19,with 9 ramus pubicus screws in 9,with 6 supraacetabular screws in 4,and with 4 both-column screws in 2 cases.TOR averaged 2.7 times,TAL 5.9 days,LOS at ICU 2.1 days,ICU admission rate 46.2％ (12 of 26),hospital LOS 7.3 days,and time for pelvic bone union 79.0 days.None patients had postoperative complications related to the pelvic fracture and no one died.According to the Matta criteria at the final follow-ups,8 cases were excellent,11 good,5 fair and 2 poor,yielding an excellent and good rate of 73.1％.Conclusion Robot-navigated minimally invasive surgery plus DCO is effective,time saving and safe treatment for polytraumatised patients with pelvic ring injuries.

To enhance primary and secondary stroke prevention, the Stroke Prevention and Control Project committee of the National Health Commission launched since October 2017 a nationwide training program for cerebrocardiac health advisors in the country. The authors introduced the standardized training system for such advisors, and the health management plan for stroke patients, in an effort to provide full-course health management scheme for stroke patients, and explore a stroke management model led by cerebrocardiac health advisors. Such efforts were designed to promote effective implementation of integrated prevention and control strategies for stroke, and provide a reference for the clinical practice of cerebrocardiac health advisors in a comprehensive and in-depth manner.

OBJECTIVETo investigate the impact of premature birth on long term cardio-cerebral vascular events of puerpera.

METHODSAmbispective cohort study method was used and 3 659 pregnant women giving birth during October 1976 to December 2008 at Kailuan medical group were included and divided into premature birth (PTB) group (n = 226) and non-PTB (NPTB) group (n = 3 433) by the history of PTB. Incidence of cardio-cerebral vascular events (myocardial infarction, cerebral infarction and cerebral hemorrhage) was obtained during follow-up. Multivariable Cox proportional hazards regression models was used to assess the relative risk of cardio-cerebral vascular events.

RESULTS(1) The childbearing age, proportion of pregnancy-induced hypertension, systolic blood pressure and diastolic blood pressure before delivery were significantly higher while weight and height of newborn were significantly less in PTB group than in NPTB group (P < 0.05 or 0.01). (2) There were 71 cardio-cerebral vascular events during the follow-up of (15.19 ± 7.75) years. In PTB group, the incidence of cardio-cerebral vascular events and myocardial infarction was 3.23/1 000 person-years and 2.05/1 000 person-years, respectively, while the corresponding incidence was 1.15/1 000 person-years and 0.42/1 000 person-years, respectively in NPTB group (all P < 0.05). After adjustment for other traditional cardiovascular risk factors, the risk of total cardio-cerebral vascular events, myocardial infarction in PTB group was 2.03 fold (95% CI: 1.02-4.04, P = 0.002) and 3.11 fold (95% CI: 1.18-8.18, P < 0.001) higher than in NPTB group.

CONCLUSIONPTB is an independent risk factor for total cardio-cerebral vascular events, especially myocardial infarction of puerpera.

Objective:To compare the short-term efficacy between femoral neck system (FNS) and cannulated compression screws (CCS) in the treatment of femoral neck fractures in young and middle-aged patients.Methods:A retrospective study was performed of the 29 young and middle-aged patients with femoral neck fracture who had been treated with FNS at Department of Orthopaedics and Traumatology, Beijing Jishuitan Hospital from January 2020 to December 2020. A control group of another 29 patients with femoral neck fracture was selected who had been treated with CCS but matched in gender, age, and body mass index. In the CCS group, there were 14 males and 15 females with an age of (48.2±12.3) years; in the FNS group, there were 14 males and 15 females with an age of (48.2±12.0) years. The fracture reduction quality, operation time, intraoperative blood loss, and femoral neck shortening, hip joint function, Barthel index and health survey 12-item short form (SF-12) score at the last follow-up and complications during follow-up were compared between the 2 groups.Results:No significant difference was found in the preoperative general data or follow-up time between the 2 groups, showing comparability ( P>0.05). The intraoperative blood loss in the CCS group [20 (10, 50) mL] was significantly less than that in the FNS group [50 (20, 50) mL], and the femoral neck shortening at the last follow-up in the CCS group (grade 1 in 5 cases; grade 2 in 18 cases and grade 3 in 6 cases) was significantly worse than that in the FNS group (grade 1 in 21 cases, grade 2 in 6 cases and grade 3 in 2 cases) ( P<0.05). No significant difference was found regarding fracture reduction quality, operation time, complications during follow-up, or Merle D'Aubigne Postel score, Barthel index or SF-12 score at the last follow-up ( P>0.05). Conclusions:In the treatment of femoral neck fractures in young and middle-aged patients, both FNS and CCS are good options for internal fixation. However, FNS can reduce the severity of femoral neck shortening and maintain the length of femoral neck better than CCS.

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.

OBJECTIVETo explore the impact of isolated diastolic hypertension (IDH) on new-onset cardio-cerebral vascular diseases (CVD).

METHODSThis cohort study involved 101 510 participants who were employees of the Kailuan Group-a state-run coal mining company, in 2006 and 2007. Among them, 6 780 subjects were diagnosed with IDH, 35 448 subjects were diagnosed with high-normal blood pressure and 19 460 subjects were diagnosed with normal tension. However, none of them had the history of either cardio-cerebral vascular disease or malignant cancer. Cardio-cerebral vascular events including cerebral infarction, cerebral hemorrhage, acute myocardial infarction were recorded every 6 months during the follow-up (47.1 ± 4.8) period. Multivariable Cox proportional hazards regression models were used to analyze the risk factors of first-ever CVD events.

RESULTS1) There were 675 CVD events occurred during the follow-up period. The incidence rates of CVD events (1.7% vs. 0.9%), cerebral infarction (1.0% vs. 0.6%) and cerebral hemorrhage (0.4% vs. 0.1%) were significantly higher in IDH group than that in the normal tension group (all P < 0.05). 2) After adjustment for other established CVD risk factors, the hazards ratios became 1.67 (95% CI: 1.28-2.17) for total CVD events and 1.59 (95% CI: 1.12-2.27) for cerebral infarction and 2.67 (95% CI: 1.54-4.65) for cerebral hemorrhage in the IDH group. 3). In stratified analysis on age, after adjustment for other established CVD risk factors, the hazards ratio was 2.22 (95% CI: 1.41-3.50) for cerebral infarction in lower 60 years old group, while the it was 7.27 (95% CI: 2.58-20.42) for cerebral hemorrhage in groups older than 60 years of age.

CONCLUSIONIDH was the independent risk factor for the total cardio-cerebral vascular events, on both cerebral infarction and cerebral hemorrhage. The predicted values of IDH for different CVD events were diverse on different age groups.
