This prospective study was conducted to compare risk factors and pregnancy outcomes between women with complete placenta previa and those with incomplete placenta previa diagnosed in mid-pregnancy.The study was carried out from April 2014 to December 2015,during which 70 patients with complete previa and 113 with incomplete previa between 20+0 weeks and 25+6 weeks of gestation were included.Maternal demographics and pregnancy outcomes were compared between the two groups.Comparisons between categorical variables were tested by chi-squared test and those between continuous variables by Student t test.Resolution ofprevia occurred in 87.43％ of the studied women.The mean gestational age at resolution was 32.1±4.4 weeks.Incidence of maternal age ≥35 years and incidence of prior uterine operation ＞3 were high in women with complete previa (28.6％vs.8.8％,P=0.003;28.6％ vs.8.8％,P=0.003).Resolution of previa occurred less often in complete previa group (74.3％ vs.95.6％,P=0.001).Women with complete previa admitted earlier (37.3±2.0 weeks vs.38.1±1.4 weeks,P=0.011) and delivered earlier (37.7±1.2weeks vs.38.3±1.4 weeks,P=0.025).Maternal age ≥35 years and prior uterine operation ＞3 increase the risk of complete previa in mid-pregnancy.Placenta previa is more likely to persist in women with complete previa than those with incomplete previa diagnosed in midpregnancy.What is more,women with complete previa in mid-pregnancy deliversearlier.

Objective:To explore a new way of pharmaceutical service mode for disease treatment. Methods:Clinical pharmacists actively participated in the pharmaceutical care for a patient with mixed liver injury, and provided clinical pharmaceutical services through the adverse reaction analysis,etiological mechanisms exploration,therapeutic drugs selection and risk factors prevention. Re-sults:Clinical pharmacists cooperating closely with physicians helped to identify problems in time,and then the medication analysis in the fields of drug selection, dose determination, efficacy evaluation and indicators detection was performed, so that the strategies on medicine treatment could be adjusted timely as the disease progressed. With the gradual recovery of liver function, the patient dis-charged after the conditions were improved. Conclusion:By participating in pharmaceutical practice,clinical pharmacists can provide clinical pharmaceutical service,which is helpful to safety improvement and efficiency of drug administration. It is also an effective way to enhance the learning ability of pharmacists,and cultivate their clinical thinking and practice capacity.

Objective: To evaluate the characteristics of left ventricular structure, function, myocardial mechanics, hemodynamics and synchrony in different phenotypes of hypertrophic cardiomyopathy (HCM) using state-of-the-art echocardiography. Methods: A consecutive series of 85 adult HCM patients who were admitted to the Xi Jing HCM center from January 2016 to November 2017 were collected. According to the peak left ventricular outflow tract pressure gradient in exercise stress echocardiography, the patients were divided into three groups: patients with non-obstructive HCM (n=28), those with labile-obstructive HCM (n=27), and those with obstructive HCM (n=30). In addition, 16 normal family members of HCM patients were included as control group. Two-dimensional speckle tracking imaging, tissue Doppler imaging and exercise stress echocardiography were used to evaluate the left ventricular function in resting and exercise states. Results: ①As compared with the control group, left ventricular end-diastolic diameter decreased and left ventricular ejection fraction increased in all three HCM groups(all P<0.05). Left ventricular maximum wall thickness and left ventricular mass index were the highest in obstructive HCM, followed by labile-obstructive and non-obstructive HCM, and the lowest in the control group (all P<0.05). ②At rest, the left ventricular global longitudinal, circumferential and radial strain (GLS, GCS and GRS), as well as the twist of obstructive HCM were significantly lower than the other three groups (all P<0.05). As compared with the control group, the GLS and twist decreased in the labile-obstructive and non-obstructive HCM(all P<0.05), but there were no significant changes of GCS and GRS (all P>0.05). The obstructive HCM had the lowest mitral annular plane systolic excursion (MAPSE) and s′, and the longest systolic peaking time standard deviation(Ts-SD) and early diastolic peaking time standard deviation(Te-SD) (all P<0.05). The left ventricular diastolic function of obstructive HCM (e′, the E/e′ ratio and the left atrial volume index) was the worst, labile-obstruction and non-obstructive HCM were better, and the control group was the best (all P<0.001). ③During exercise, the GLS, GCS, GRS, twist of the left ventricle and the MAPSE were the lowest in the obstructive HCM, which increased in the labile-obstructive and non-obstructive HCM, and were best in the control group. The Ts-SD and Te-SD were the shortest in the control group, were prolonged in non-obstructive and labile-obstruction HCM, and were longest in obstructive HCM (all P<0.05). Additionally, the exercise time of the control group was the longest, followed by non-obstructive and labile-obstruction HCM, and the shortest in the obstructive HCM (all P<0.05). The METs of obstructive HCM were significantly lower than the other three groups (all P<0.05). Conclusions In obstructive HCM, the left ventricular systolic strain and synchronization, as well as the MAPSE, are significantly impaired in patients both at rest and during exercise. The patients with labile-obstructive and non-obstructive HCM have reduced left ventricular GLS, twist, and e′, but normal left ventricular GCS, GRS, synchrony, and MAPSE at rest, which are all impaired during exercise.

Objective Meningiomas in the trigone of the lateral ventricle are characterized by deep location and low inci-dence. A few studies have been done on its treatment at home and abroad. This study was to explore the access,techniques,and clini-cal effect of microsurgery for lateral ventricular trigone meningiomas (LVTM). Methods We retrospectively analyzed the clinical data about 36 cases of LVTM treated by microsurgery in our hospital from December 2011 to December 2015. The operation involved lumbar cistern tube drainage, intraoperative drainage of cerebrospinal fluid, a unilateral parieto-occipital U-shaped cut, approach through the interparietal fissure,a sagittal incision about 3 cm long at the interparietal fissure for exposure and resection of the tumor. We followed up the patients for a mean of 17 months postoperatively and analyzed the results and complications. Results Simpson grade I removal of the tumors was achieved in all the 36 cases. Postoperative complications included homonymous hemianopia in 4 cases, central nervous system infections in 3,secondary epilepsy in 2,subcutaneous hydrops in 2,and intratumoral hemorrhage in 1 (which necessitated a second operation). Extended temporal horn of the right lateral ventricle occurred at 32 months after surgery,which was treated by fistulation. Homonymous hemianopia was improved in 2 of the 4 ca-ses. All the patients were capable of daily life activities and none experienced recurrence. Conclusion Sufficient preoperative evalu-ation of the tumor characteristics,rational selection of surgical approach,and expert operation techniques are the key factors for the mi-crosurgical treatment of meningiomas in the trigone of the lateral ventricle.

Objective: To understand the incidence of chronic obstructive pulmonary disease (COPD) in the Suzhou cohort, and explore the risk factors for the development of COPD in Suzhou, and provide a scientific basis for COPD prevention. Methods: This study was based on the China Kadoorie Biobank project in Wuzhong District, Suzhou. After excluding individuals with airflow obstruction and self-reported chronic bronchitis, emphysema, or pulmonary heart disease at baseline, 45 484 individuals were finally included in the analysis. Cox proportional risk models were used to analyze risk factors of COPD and calculate hazard ratios and 95% confidence interval (CI) in the Suzhou cohort. The effect modifications of smoking on the association between other risk factors and COPD were evaluated. Results: Complete follow-up was available through December 31, 2017. Participants were followed up for a median of 11.12 years, and 524 individuals were diagnosed with COPD during the follow-up period; the incidence was 105.54 per 100 000 person-years. Multivariate Cox proportional risk regression models showed that age (HR=3.78, 95%CI:3.32-4.30), former smoking (HR=2.00, 95%CI:1.24-3.22), current smoking (<10 cigarettes/day, HR=2.14, 95%CI:1.36-3.35;≥10 cigarettes/day, HR=2.69, 95%CI:1.60-4.54), history of respiratory disease (HR=2.08, 95%CI:1.33-3.26), daily sleep duration ≥10 hours (HR=1.41, 95%CI:1.02-1.95) were associated with increased risk of COPD. However, education level of primary school and above (primary or junior high school, HR=0.65, 95%CI:0.52-0.81; high school and above, HR=0.54, 95%CI:0.33-0.87), consuming fresh fruit daily (HR=0.59, 95%CI:0.42-0.83) and consuming spicy food weekly (HR=0.71, 95%CI:0.53-0.94) were associated with reduced risk of COPD. Conclusions: The incidence of COPD is low in Suzhou. Older age, smoking, history of respiratory disease, and long sleep duration were risk factors for the development of COPD in the Suzhou cohort.

Alzheimer's disease (AD) is associated with the impairment of white matter (WM) tracts. The current study aimed to verify the utility of WM as the neuroimaging marker of AD with multisite diffusion tensor imaging datasets [321 patients with AD, 265 patients with mild cognitive impairment (MCI), 279 normal controls (NC)], a unified pipeline, and independent site cross-validation. Automated fiber quantification was used to extract diffusion profiles along tracts. Random-effects meta-analyses showed a reproducible degeneration pattern in which fractional anisotropy significantly decreased in the AD and MCI groups compared with NC. Machine learning models using tract-based features showed good generalizability among independent site cross-validation. The diffusion metrics of the altered regions and the AD probability predicted by the models were highly correlated with cognitive ability in the AD and MCI groups. We highlighted the reproducibility and generalizability of the degeneration pattern of WM tracts in AD.

In the past 37 years, human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) has undergone various major transmission routes in China, with the world most complex co-circulating HIV-1 subtypes, even the prevalence is still low. In response to the first epidemic outbreak of HIV in injecting drug users and the second one by illegal commercial blood collection, China issued the Anti-Drug Law and launched the Blood Donation Act and nationwide nucleic acid testing, which has avoided 98,232 to 211,200 estimated infections and almost ended the blood product-related infection. China has been providing free antiretroviral therapy (ART) since 2003, which covered >80% of the identified patients and achieved a viral suppression rate of 91%. To bend the curve of increasing the disease burden of HIV and finally end the epidemic, China should consider constraining HIV spread through sexual transmission, narrowing the gaps in identifying HIV cases, and the long-term effectiveness and safety of ART in the future.
