RESUMEN
Objective: To investigate the impact of non-high-density lipoprotein cholesterol (non-HDL-C) level on major adverse cardiovascular and cerebrovascular events (MACCE) and all-cause mortality in the Kailuan Study cohort undergoing revascularization. Methods: This is a prospective cohort study, with participants from the Kailuan Study cohort who participated in physical examinations from 2006 to 2020 and received revascularization therapy for the first time. According to the level of non-HDL-C, the study subjects were divided into 3 groups:<2.6 mmol/L group, 2.6-<3.4 mmol/L group, and≥3.4 mmol/L group. Annual follow-up was performed, and the endpoint events were MACCE and all-cause mortality. Cox proportional regression model was implemented to estimate the impact on MACCE and all-cause mortality associated with the different non-HDL-C groups. The partial distributed risk model was used to analyze the impact of different non-HDL-C levels on MACCE event subtypes, and death was regarded as a competitive event. The restricted cubic spline regression model was used to explore the dose-response relationship between non-HDL-C level and all-cause mortality, MACCE and its subtypes. Results: A total of 2 252 subjects were enrolled in the study, including 2 019 males (89.65%), aged (62.8±8.3) years, the follow-up time was 5.72 (3.18, 8.46) years. There were 384 cases(17.05%) of MACCE and 157 cases(6.97%) of all-cause mortality. Compared with patients with non-HDL-C≥3.4 mmol/L, patients with non-HDL-C<2.6 mmol/L were associated with a 38% reduced risk of MACCE after revascularization [HR=0.62(95%CI: 0.48-0.80)]. Every 1 mmol/L decrease in non-HDL-C was associated with a 20% reduction in the risk of MACCE [HR=0.80(95%CI: 0.73-0.88)]. The results of restricted cubic spline also showed that non-HDL-C levels after revascularization therapy were positively correlated with MACCE events (overall association P<0.001, non-linear association P=0.808). For all-cause mortality, compared to the non-HDL-C≥3.4 mmol/L group, the HR for all-cause mortality after revascularization in non-HDL-C<2.6 mmol/L group was 0.67(95%CI: 0.46-1.01). Every 1 mmol/L decrease in non-HDL-C was associated with a 15% reduction in the risk of all-cause mortality [HR=0.85(95%CI: 0.73-0.99)]. The restricted cubic spline results showed a linear association between non-HDL-C levels after revascularization therapy and the risk of all-cause mortality (overall association P=0.039, non-linear association P=0.174). Conclusion: The decrease in non-HDL-C levels after revascularization were significantly associated with a reduced risk of MACCE and all-cause mortality.

Objective: To evaluate the impact of individual and combined assessment of age- and sex-specific brachial-ankle pulse wave velocity (baPWV) and pulse pressure (PP) on all-cause mortality. Methods: This study is a prospective cohort study. Individuals participated in the Kailuan Study and completed baPWV measurements between 2010 and 2016 were included in this study. After stratifying by sex, 75th percentile baPWV and PP values for different age group were calculated at five years interval. BaPWV and PP values below the 75th percentile were defined as normal, and those above or equal to the 75th percentile were defined as increased. The participants were allocated to four groups according to their PP and baPWV status: normal baPWV/PP group, high baPWV/normal PP group, normal baPWV/high PP group and high baPWV/PP group. The primary outcome was all-cause mortality during the follow-up period. Cox proportional hazards models were used to explore the impact of individual and combined assessment of baPWV and PP on all-cause mortality events. Results: A total of 39 339 participants were enrolled in this study, aged (49.3±12.8) years, of which 28 731 (73.03%) were males. There were 23 268, 6 025, 6 210 and 3 836 cases in the normal baPWV/PP group, high baPWV/normal PP group, normal baPWV/high PP group and high baPWV/PP group, respectively. The average follow-up duration was (4.98±2.53) years. During the follow-up period, all-cause mortality occurred in 998 individuals. Multivariate Cox regression analysis showed increased risk of all-cause mortality in the high baPWV/normal PP group (HR=1.27, 95%CI 1.07-1.50), and in the high baPWV/PP group (HR=1.33, 95%CI 1.08-1.65) compared to the normal baPWV/PP group. Increased pulse pressure alone had no impcat on all-cause death (HR=1.06, 95%CI 0.87-1.29). Conclusions: The risk of all-cause mortality significantly increases with increased age-and sex-specific baPWV and PP values. BaPWV may be a better predictor of all-cause mortality than PP in this cohort.

Objective: To explore the methods and appliaction value for self-constructing brainstem fiber bundles by neurosurgeon through 3D-Slicer software in neurosurgical preoperative planning. Methods: The DCIOM format imaging data of 31 patients with neurosurgical brainstem lesions were collected who admitted to Neurosurgery Department at the First Affiliated Hospital of Chongqing Medical University from June 2018 to May 2019 and imported into the 3D-Slicer software system. The neurosurgery specialists independently constructed the fiber bundles to generate two-dimensional Fraction Anisotropy maps, Directionally Encoded Color maps and three-dimensional fiber bundle tracing maps. Building a preopertive virtual pathological anatomical imaging system and understanding the three-dimensional pathological anatomical relationship between lesions and brain stem fiber bundles to develop an accurate surgical approach and simulate surgicalprocedures before surgery. Results: All cases were reconstructed by neurosurgeon, and the self-constructed 3D virtual images were used to develop the surgical plan. All the operations were successfully completed under the assistance of microsurgical techniques and neuroendoscopy while avoiding fiber bundles as much as possible, and the total or subtotal tumor was achieved without damage to the fiber bundle. After operation, the symptoms of new brainstem fiber bundle injury were mild. 31 patients were followed up 3 months after operation without obvious symptoms of brainstem fiber bundle injury, and 31 patients were followed up 6 months after operation without obvious symptoms of brainstem fiber bundle injury. Conclusions: Constructing brainstem fiber bundles by neurosurgeon can accurately and purposefully reconstruct the shape of brainstem fiber bundles, so that neurosurgeons can more accurately understand the three-dimensional pathological anatomical relationship between tumor and brain stem fiber bundles. In order to formulate the surgical plan in a more reasonable way, choose the optimal surgical approach, understand the location of the "relative safe area" , and be more confident to avoid damage to the brain stem fiber bundle while achieving subtotal or total resection of the tumor,also the nerve function of the patient is preserved as much as possible.

Objective: To investigate the impact of change of ideal cardiovascular behavior and related factors on healthy vascular aging(HVA). Methods: This study was a multi-center cross-sectional survey. Six thousand three hundred and sixteen participants who underwent at least 2 healthy examinations from 2006 to 2015 at 11 hospitals, including Kailuan Hospital and so on, and examined brachial-ankle pulse wave velocity (baPWV) during 2010 and 2016, with available information about cardiovascular behavior and factors were included. The cardiovascular health score (CHS) was calculated. Basic CHS was collected from the first examination. The second CHS derived from the healthy examination in the same year of baPWV examination. Change of cardiovascular health score (ΔCHS) was calculated. Participants were defined into 5 groups according to ΔCHS, namely ΔCHS≤-2 (n=2 166), ΔCHS=-1 (n=1 284), ΔCHS=0 (n=1 187), ΔCHS=1 (n=860), and ΔCHS≥2 (n=819). Participants' characteristics, value of baPWV and proportion of HVA were compared among different groups. Multiple logistic regression analysis was used to investigate the association between ΔCHS and HVA. The ΔCHS was recalculated and included in multiple logistic regression analysis model again after each component of the cardiovascular health metrics was removed separately in order to investigate effects of removal factors on HVA by observing changes in effect values. Results: The percentage of the participants with HVA in the group of ΔCHS≤-2, ΔCHS=-1, ΔCHS=0, ΔCHS=1 and ΔCHS≥2 were 23.3%(505/2 166), 27.8%(357/1 284), 28.7%(341/1 187),31.9%(274/860) and 33.9%(278/819), respectively. After adjustment for age, sex, income, education, alcohol consumption and the basic CHS, a significant positive association between ΔCHS and proportion of participants with HVA was observed (OR=1.50, 95%CI 1.44-1.56). Multiple regression analysis after removing each single cardiovascular behavior or factor showed that the OR value decreased as follow systolic blood pressure (OR=1.04, 95%CI 1.00-1.09), fasting blood glucose (OR=1.14, 95%CI 1.09-1.18), physical exercise (OR=1.16, 95%CI 1.11-1.21), salt intake (OR=1.17, 95%CI 1.12-1.22), body mass index (OR=1.18, 95%CI 1.13-1.23), smoking(OR=1.18, 95%CI 1.13-1.23) and total cholesterol (OR=1.20, 95%CI 1.16-1.24). Conclusion: The improvement of every ideal cardiovascular behavior and factor is associated with the increase of the proportion of HVA population.

Objective: To prospectively explore the relationship between resting heart rate (RHR) and risk of new-onset heart failure. Methods: It was a prospective cohort study. People who attended the physical examination of Kailuan Group Company in 2006 and with complete electrocardiography (ECG) recordings were eligible for this study. A total of 88 879 participants aged 18 years old or more who were free of arrhythmia, a prior history of heart failure and were not treated with ß-blocker were included. Participants were divided into 5 groups according to the quintiles of RHR at baseline (Q(1) group, 40-60 beats/minutes (n=18 168) ; Q(2) group, 67-70 beats/minutes (n=18 970) ; Q(3) group, 71-74 beats/minutes (n=13 583) ; Q(4) group, 75-80 beats/minutes (n=22 739) ; and Q(5) group,>80 beats/minutes (n=15 419) ) .The general clinical data and laboratory test results were collected. The outcome was the first occurrence of heart failure at the end of follow-up (December 31, 2016) .We used Cox regression model to examine the association between RHR and the risk of new-onset heart failure. Hazard ratio (HR) with 95% confidence intervals (CI) were calculated using Cox regression modeling. Results: Among the included patients 68 411 participants were male, mean age was (51.0±12.3) years old, and RHR was (74±10) beats/minutes. Statistically significant differences among the RHR quintiles were found for the following variables: age, gender, systolic blood pressure, diastolic blood pressure, triglycerides, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, fasting blood glucose, body mass index, the level of high-sensitivity C-reactive protein, education status, physical activity, smoking status, drinking status, history of diabetes, history of hypertension and history of use antihypertensive drugs (all P<0.01) . Higher RHR was linked with higher prevalence of diabetes, hypertension history, and higher systolic blood pressure, diastolic blood pressure and FBG levels (all P<0.01). After a mean follow-up of 9.5 years, the incidence of new-onset heart failure in Q(1), Q(2), Q(3), Q(4) and Q(5) groups was 1.60%(290/18 168), 1.36%(258/18 970), 1.80%(245/13 583), 1.76%(400/22 739) and 2.35%(362/15 419),respectively (P<0.01) . The person-year incidence of heart failure in Q(1), Q(2), Q(3), Q(4) and Q(5) groups was 1.7, 1.5, 1.9, 1.9 and 2.6 per 1 000 person-years respectively. Compared with the Q(2) group, multivariate analysis with adjustment for major traditional cardiovascular risk factors showed that HRs of Q(3),Q(4),and Q(5) group were 1.23 (95%CI 1.03-1.48, P<0.05) , 1.19 (95%CI 1.01-1.41, P<0.05) , 1.39 (95%CI 1.18-1.65, P<0.01) , respectively. In the absence of hypertension, diabetes, smoking and acute myocardial infarction, the Cox regression model showed that compared with Q(2) group, the HR of new-onset heart failure in Q(5) group was 1.58 (95%CI 1.02-2.45, P<0.05) . Conclusion: Increased RHR is associated with increased risk of new-onset heart failure in this cohort.

Objective: To investigate the efficacy of cognitive-behavioral therapy for insomnia (CBT-i) or combination with tapered hypnotic agents. Methods: Seventy-five patients were randomized into either CBT-i group (n=37) or combination group (n=38). The duration of treatment lasted for 8 weeks. The efficacy was evaluated by Pittsburgh sleep quality index (PSQI), Beck depression index (BDI) , Beck anxiety inventory (BAI) and sleep diary variables at baseline, middle and end of treatment. Results: (1)Compared with the results at baseline, the total scores of PSQI,BDI and BAI in both groups significantly decreased at the end of treatment: CBT-i group, PSQI (4.7±2.5) vs. (12.9±3.5); BDI (3.2±4.4) vs. (9.7±6.4); BAI (4.2±5.6) vs. (10.7±8.1); and combination group, PSQI (5.8±2.8) vs. (13.9±3.1); BDI (4.5±4.8) vs. (13.8±8.7); BAI (4.4±4.0) vs. (14.1±6.3) (all P<0.01). (2) Compared with the results at baseline, subjective sleep quality (SQ), sleep onset latency (SOL), sleep efficiency (SE), sleep disturbance (SD) and used sleep medication (USM) in PSQI in combination group significantly decreased at week 4 and 8 (all P<0.05) . The total sleep time (TST) and daytime dysfunction (DF) in PSQI significantly decreased at week 8 (both P<0.05) . (3) Compared with combination group, improvement of SOL and SE in CBT-i group was superior (both P=0.01). Conclusions: CBT-i for chronic insomnia is effective in both CBT-i alone and combination with tapered hypnotic agents. CBT-i group is superior in improving SOL and SE.

Objective: To identify the therapeutic efficacy of lithium chloride (LiCl) on phosphatase and tensin homolog deleted on chromosome ten (PTEN)-deficient tumors. Methods: First, the Catalogue of Somatic Mutations in Cancer for mutation spectrum of human endometrial carcinoma samples was analyzed. Second, the relationship between PTEN abundance and LiCl inhibition of endometrial cancer cell lines using Pten(+/+) and Pten(-/-) mouse embryonic fibroblast (MEF) lines was investigated. Moreover, potential alterations of mammalian target of rapamycin (mTOR) signaling pathway after treatment with LiCl were checked.Last,LiCl's efficacy on PTEN null tumors was studied. Results: PTEN was mutated in 39% of endometrial carcinomas. LiCl preferentially inhibited the proliferation of PTEN-deficient endometrial carcinoma cells and MEFs. Furthermore, LiCl blocked PTEN-deficient tumor development. Mechanistically, LiCl down-regulated mTOR signaling. Conclusions: PTEN is the most frequently mutated gene in endometrial carcinoma.By targeting mTOR signaling pathway,LiCl is a promising regimen for the treatment of tumors with PTEN deficiency.

Objective: To evaluate the feasibility and clinical value of suprapubic-assisted laparoendoscopic single-site surgery (SA-LESS) in nephroureterectomy using method of transvaginal natural orifice specimen extraction (NOSE) (SA-LESS+TV-NOSE NU). Methods: Four patients (three cases of renal pelvic carcinoma and one case of ureteral carcinoma) undergoing SA-LESS+TV-NOSE NU were enrolled between April 2015 and January 2016. After general anesthesia, the patients were placed in the lithotomy position with the affected side elevated by 60°. Two trocars were inserted at the medial margin of umbilicus, and the third one was inserted into abdominal cavity at the superior margin of pubic symphysis. The operation was performed under a direct vision with a 5.4 mm 0° flexible-tip laparoscope. Firstly, the distal ureter was isolated completely and blocked by a Hem-O-lok clip. Then, the laparoscopic nephrectomy was performed according to the standard method. Finally, the bladder cuff excision was executed and the incision was sutured. The intact specimen was placed inside a homemade bag and removed through the incision at posterior vaginal fornix. Results: All the procedures were successfully performed. The median operative time was 150 (range: 120 to 210) minutes, and the median estimated blood loss was 180 (range: 80 to 350) ml. No major perioperative complications occurred. The mean visual analogue score (VAS) of 24 hours and 48 hours after operation were 3.25 (range: 2 to 5) and 2.25 (range: 2 to 3). All the patients resumed ambulation on postoperative day 1. Pelvic drainage tube was removed on postoperative day 2-4. On postoperative day 7, urethral catheter was removed. The patients were discharged on postoperative day 7-9. During the follow-up of 20-29 months, the patient recovered well with no case of incisional hernia and pelvic, abdominal infections. The vaginal fornix incision healed well, and the umbilical and suprapubic puncture scars were not obvious. All the patients completed the patient-assessed acromegaly symptom questionnaire PASQ. The average PSAQ score of 3 months after surgery was 34.5. Three of them restarted their sex lives, with an average female sexual function index score of 16.0, which was not significantly different with that of preoperation (15.6). There was no tumor recurrence, metastasis and implantation in all cases. Conclusion: SA-LESS+TV-NOSE NU is safe and feasible for upper tract urothelial carcinoma with faster postoperative recovery, less pain, shorter hospitalization time, better cosmetic results, and does not cause negative effect on the female sexual function.

BACKGROUND: Cognitive reserve (CR) has been associated with better cognitive function and lower risk of depression in older people, yet it remains unclear whether CR moderates the association between mood and cognition. This study aimed to investigate whether a comprehensive indicator of CR, including education, occupation and engagement in cognitive and social activities, acts as a moderator of this association. METHODS: This was a cross-sectional study utilising baseline data from the Cognitive Function and Ageing Study II (CFAS II), a large population-based cohort of people aged 65+ in England. Complete data on the measures of CR, mood and cognition were available for 6565 dementia-free individuals. Linear regression models were used to investigate the potential modifying effect of CR on the association between cognition and mood with adjustment for age, sex and missing data. RESULTS: Levels of CR did moderate the negative association between mood and cognition; the difference in cognition between those with and without a clinical level mood disorder was significantly smaller in the middle (-2.28; 95% confidence interval (CI) -3.65 to -0.90) and higher (-1.30; 95% CI -2.46 to -0.15) CR groups compared with the lower CR group (-4.01; 95% CI -5.53 to -2.49). The individual components of CR did not significantly moderate the negative association between mood and cognition. CONCLUSION: These results demonstrate that CR, indexed by a composite score based on multiple indicators, can moderate the negative association between lowered mood and cognition, emphasising the importance of continuing to build CR across the lifespan in order to maintain cognitive health.

Hepatitis B virus (HBV) reactivation is a remarkable risk during the chemotherapy for solid tumour patients. Nucleos(t)ide analogues (NAs) are recommended as prophylaxis for the reactivation of HBV infection in some cancer patients prior to systemic chemotherapy. Therefore, we performed a meta-analysis aiming to determine the efficacy of prophylactic lamivudine on prevention of HBV reactivation and its related negative outcomes among solid tumour patients with chronic HBV infection receiving systemic chemotherapy. The primary outcome was HBV reactivation, and the secondary outcomes were HBV-related hepatitis, chemotherapy disruption, mortality and tyrosine-methio-nine-aspartate-aspartate (YMDD) mutations. Twelve original researches involving 1,101 patients were analysed in this study. The relative risk of HBV reactivation in patients with lamivudine prophylaxis was significantly lower than that without prophylaxis (RR = 0.17, 95% CL: 0.10-0.29, p < .00001). Lamivudine prophylaxis reduced the relative risk of hepatitis (p < .00001), chemotherapy disruptions (p = .01) and mortality (p = .08) due to HBV reactivation. Lamivudine prophylaxis is effective in reducing HBV reactivation and its related negative outcomes, such as hepatitis and chemotherapy disruption and mortality among chemotherapeutic solid tumour patients with chronic HBV infection. Future studies should lay more emphasis on the early HBV screening, mode of treatment and duration of NAs prophylaxis among solid tumour patients receiving chemotherapy.

Objectives: To evaluate the effectiveness of cognitive behavior therapy for insomnia (CBT-i) in chronic insomnia patients in terms of the improvements of psychological and sleep diary parameters. Methods: Patients who met the diagnostic criteria of chronic insomnia, were divided into primary group or comorbid group. Both groups received standard CBT-i interventions. Psychological scales and sleep diaries were used to evaluate participants' severity of insomnia and psychological conditions related to insomnia at four time points: before intervention (baseline), immediate after intervention, 4 weeks and 16 weeks after intervention. Results: Both groups achieved significant improvements after intervention on psychological measurements and sleep diary parameters. Such improvements were maintained at 4-week and 16-week follow-ups. The sleep diary data indicated that by the end of the intervention, there were significant differences on sleep onset latency (51.72 min to 10.53 min in primary group, P<0.01; 59.26 min to 15.67min in comorbid group, P<0.01) and sleep efficiency (71% to 95% in primary group, P<0.01; 68% to 90% in comorbid group, P<0.01). There were differences on sleep onset latency (10.00 min vs. 13.93 min, P<0.05), total sleep time (355.71 min vs. 327.85 min, P<0.05) and sleep efficiency (95% vs. 91%, P<0.01) in primary group and comorbid group respectively. No differences were found on wake after sleep onset in the two groups. Conclusions: Chronic insomnia patients with or without comorbidities both have improvements after CBT-i. Sleep diary parameters rather than psychological measurements are different in two groups. Thus, CBT-i is an effective non-pharmaceutical therapy inpatients with chronic insomnia.

Objective: To study the value of neuroendoscopy assisted microneurosurgery technique in the treatment of posterior cranial fossa lesion. Methods: Clinical data of 36 patients with posterior fossa lesions who accepted neuroendoscopy assisted microneurosurgery (NEAM group) in the department of neurosurgery of the First Affiliated Hospital of Chongqing Medical University, from January 2014 to December 2016, were retrospectively enrolled. A total of 113 cases diagnosed with the same lesions and accepted conventional microneurosurgery (non-NEAM group) in the same period were analyzed as control group. The total tumor resection rate, postoperative leakage of cerebrospinal fluid, intracranial infection, operating time and the recovery of facial nerve function were compared between the two groups. Results: Ninety-three patients with acoustic neuroma were analyzed, which were divided into non-NEAM group 78 cases (removed posterior lip of internal auditory canal in different degrees) and NEAM group 15 cases (not removed posterior lip of internal auditory canal). The total tumor resection rate and postoperative facial nerve function had no significant statistical differences between two groups. The operating time of NEAM group was longer than that of non-NEAM group (P=0.048, P<0.05), but the rate of leakage of cerebrospinal fluid and intracranial infection did not increase. Twenty-seven cases were diagnosed with cerebellopontine angle cholesteatoma. These cases were divided into two groups, 17 cases in non-NEAM group and 10 cases in NEAM group. NEAM group have higher total tumor resection rate (P=0.014, P<0.05), better short-term postoperative facial nerve function (P=0.039, P<0.05), and longer operating time (P=0.015, P<0.05), compared with non-NEAM group. No significant statistical differences were observed on long-term postoperative facial nerve function and postoperative complications. Of the 16 cases diagnosed tentorial meningioma, 10 cases were in non-NEAM group and 6 cases in NEAM group. Six cases in non-NEAM group and 4 cases in NEAM group were total removal. For the mean operating time, non-NEAM group was (6.6±1.0) hours and NEAM group was (7.1±0.7) hours. Thirteen cases were with fourth ventricular cholesteatoma, which all were totally resected, and 8 cases were in non-NEAM group and 5 cases in NEAM group. For non-NEAM group, 5 cases dissected cerebellar vermis and the mean operating time is (6.0±0.7) hours. However, NEAM group all did not dissect cerebellar vermis and the mean operating time is (6.4±0.4) hours. Conclusions: Neuroendoscopy assisted microneurosurgery for cranial fossa lesions was benefit to totally resect tumor and reduce unnecessary injury. It needed longer operating time, but not increase postoperative intracranial infection.

Objective: To investigate the effectiveness and clinical significance of dynamic retraction microneurosurgery for the treatment of medial tentorial meningiomas. Methods: From January 2011 to December 2016, a cohort of 28 patients with medial tentorial meningiomas were treated by microneurosurgery at the First Affiliated Hospital of Chongqing Medical University. Patients who treated intraoperatively with dynamic retraction surgery from January 2014 to December 2016 were assigned into dynamic retraction group, and those with fixed retractors intraoperatively from January 2011 to December 2013 were assigned into retractor group. The surgical approaches tailored in our patients were based on predominant direction of tumor extension. The extent of tumor resection was scored according to the Simpson's classification scale. Comparisons of tumor size, operation time, hospitalization time, retraction-related injury, tumor Simpson resection grade and Karnofsky Performance Scale(KPS) score six months after surgery were also made between two groups. Results: A total of 12 patients(retractor group) were treated with the use of self-retaining brain retractors intraoperatively and dynamic retraction surgical procedure was performed intraoperatively in 16 patients(dynamic retraction group). The difference between two groups with regard to sex, age, tumor size, operation time and tumor Simpson resection grade was not statistically significant(all P>0.05). The mean duration of hospital time was shorter in the dynamic retraction group than that in the retractor group(18.3 d±1.8 d vs 20.2 d±1.3 d, P=0.004). The dynamic retraction group had lower incidence of retraction-related injury compared with the retractor group(1/16 vs 6/12), P=0.022]. The dynamic retraction group had better neurological recovery rate with KPS >80 evaluated six months after surgery compared with the retractor group(14/16 vs 5/12, P=0.017). Conclusions: Dynamic retraction microneurosurgery for the treatment of medial tentorial meningiomas is feasible, which can obviate or reduce the amount of brain retraction needed, and may be of help in lowering the risk of postoperative neurological deficits and complications and leading to reduced hospitalization cost and improved surgical outcomes.

OBJECTIVE: To investigate the distribution and influencing factors of orthostatism brachial-ankle pulse wave velocity(baPWV) and ankle brachial index(ABI) in the elderly. METHODS: Participants were selected with random sampling from ≥60 years old retired workers, who underwent 2010 to 2011 health check-up in the Tangshan Kailuan Hospital, Kailuan Linxi Hospital, Kailuan Zhaogezhuang Hospital. Multivariate linear regression analysis was used to analyze the influencing factors of orthostatism and supine baPWV and ABI in the elderly. RESULTS: (1) A total of 2 464 participants were included, and 1 601 participants (1 065 males(66.5%) and (67.5±6.1) years old) with integral data were analyzed. Orthostatism baPWV was (3 885.4±1 503.5)cm/s and Supine baPWV was (1 761.2±371.4)cm/s.Orthostatism ABI was 1.54±0.21 and supine ABI was 1.10±0.12. Orthostatism baPWV increased with increasing age, while orthostatism ABI decreased with aging(trend test, both P<0.01)in <65, 65-69, 70-74, and ≥75 years old participants.(2) Multiple linear regression analysis showed that the age(ß=0.19, P<0.01), lower limbs orthostatism systolic blood pressure(ß=0.18, P<0.01), lower limbs supine systolic blood pressure (ß=0.14, P<0.01), orthostatism heart rate (ß=0.30, P<0.01), supine heart rate (ß=0.23, P<0.01), body mass index (ß=-0.18, P<0.01) were associated with orthostatism baPWV, and female(ß=-0.055, P=0.01), upper limb orthostatism systolic blood pressure (ß=-0.834, P<0.01), lower limbs orthostatism systolic blood pressure (ß=0.708, P<0.01), lower limbs supine systolic blood pressure (ß=0.099, P<0.01) and fasting blood glucose(ß=-0.085, P<0.01) were associated with orthostatism ABI. CONCLUSIONS: Orthostatism baPWV and ABI were significantly higher than those of supine's. Age, lower limbs orthostatism and supine systolic blood pressure, orthostatism and supine heart rate, body mass index were associated with orthostatism baPWV. Female, upper limb orthostatism systolic blood pressure, lower limbs orthostatism, supine systolic blood pressure and fasting blood glucose were associated with orthostatism ABI in the elderly.

OBJECTIVE: To investigate the association between different kinds of systolic blood pressure (SBP, including office, visit-to-visit, 24-hour ambulatory) and vascular damages (represented by carotid intima-media thickness, CIMT; brachial-ankle pulse wave velocity, baPWV) in the elderly. METHODS: A total of 2 814 participants aged of ≥60 years old and retired employees were selected with random sampling method from the individuals who took part in 2006-2007, 2008-2009, 2010-2011 health examination in Tangshan Kailuan Hospital, Kailuan Linxi Hospital, Kailuan Zhaogezhuang Hospital and with 24-hour ambulatory blood pressure monitoring data, CIMT and baPWV.Finally, 2 146 participants (1 438 males, average age (67.3±6.0) years old) were included to the analysis.Multivariable regression analysis was used to analyze association between the office, visit-to-visit, 24-hour, day-time, night-time SBP and CIMT and baPWV, respectively. RESULTS: (1) The average SBP, DBP, CIMT and baPWV were (137.0±20.4) mmHg(1 mmHg=0.133 kPa), (83.5±11.0) mmHg, (0.92±0.18)mm and (1 781.7±353.2)cm/s.(2) The participants were divided into high and low level groups according to the median of different SBPs, respectively.The results indicated that CIMT and baPWV were significantly higher in high level groups than in low level groups (all P<0.01). (3) After adjusting for gender and age, the partial correlate analysis showed that the office, visit-to-visit, 24-hour, day-time, night-time SBP positively associated with CIMT and baPWV (all P<0.01). (4) After adjusting for confounding factors, multivariable regression analysis showed that the office, visit-to-visit, 24-hour, day-time, night-time SBP were positively and linearly associated with CIMT and baPWV in total cohort, and standard regression coefficients were 0.157, 0.208, 0.175, 0.169, 0.163, 0.479, 0.420, 0.401, 0.389 and 0.354, respectively.In addition, similar results were observed in male and female participants but there was no significance between night-time SBP and CIMT in female participants. CONCLUSIONS: Office, visit-to-visit, 24-hour, day-time, night-time SBP are associated with vascular damages, and the best associations are observed between visit-to-visit SBP and vascular function damage.

BACKGROUND: This study surveyed the characteristics of white matter (WM) micro-integrity in patients who were diagnosed with major depressive disorder (MDD) without co-morbidities. METHOD: A total of 44 patients with MDD and 27 normal controls were enrolled in our study. Diffusion tensor imaging images of patients and controls were pre-processed and analysed to estimate differences in WM micro-integrity between patients and controls by performing comparisons of the values obtained from fractional anisotropy (FA). FA outputs of patients and controls were compared by a non-parametric permutation-based method with global brain volume, age and gender as covariates. In addition, the between-group differences of radial diffusivity (RD) and axial diffusivity (AD) were assessed to explain the alterations in FA values. Correlations between clinical variables (such as depression severity, anxiety severity, illness duration) and FA values were also estimated in each group and across both groups. RESULTS: The patients with MDD had significantly lower FA values than the controls, for the left superior longitudinal fasciculus (SLF) and the right anterior thalamic radiation (ATR). The reductions in FA values occurred in combination with elevated RD values in the bilateral SLF and decreased AD values in the bilateral ATR. FA values were negatively correlated with depression severity in the SLF and with illness duration in the right SLF and ATR. CONCLUSIONS: MDD patients had significant alterations in the WM micro-integrity of the left SLF and the right ATR.

The dyschromatoses are a group of disorders characterized by the presence of both hyperpigmented and hypopigmented macules, many of which are small in size and irregular in shape. Localized dyschromatosis is a rare manifestation of dyschromatosis. Localized dyschromatosis showing segmental distribution may be a result of degeneration of localized cutaneous nerves. We report a case of localized dyschromatosis, with segmental distribution, with co-occurrence of blue naevi and cherry angiomas.
