The Leguminosae perennial vines of Callerya and Millettia have many species and wide distribution， not only can be used for medicines， but also they have ornamental and insecticidal effects. With increasing demand for Spatholobi Caulis， and the reserves of wild medicinal materials are on the verge of exhaustion， resulting in the increasing number of mixtures and substitutes in the market， which makes it urgent to study the origin of Spatholobi Caulis. By referring to related literature， there are three major origins of Spatholobi Caulis， including Callerya， Millettia and Spatholobus. Callerya is separated from Millettia， they are divided and united for many times， now the official website of Flora of China has accepted the revision of them as two genera. This paper intends to compare the chemical components and pharmacodynamic effects of Callerya and Millettia， aiming to explore the similarities and differences between the two genera， so as to determine the rationality and necessity of separating Callerya from Millettia. After comparing， it was found that the chemical composition and pharmacodynamic effects of the two genera were different， which supported the separation of Callerya from Millettia， and it was not recommended to mix use of them.

Objective: To analyze the prognostic factors of transfusion-dependent non-severe aplastic anemia (TD-NSAA) patients treated with cyclosporine A (CsA) and androgen. Methods: Clinical data of 77 consecutive TD-NSAA patients treated with CsA and androgen were retrospectively analyzed between 2010 and 2013. We obtained clinical manifestations and baseline parameters of routine blood test from responders, and compared those with non-responders. All data were analyzed by univariate analysis and multivariate analysis. Results: In 77 patients, there were 43 (55.8%) patients achieved hematological response after 6 months'treatment, and 53 (68.8%) patients got response after 12 months. Univariate analysis showed that platelets baseline was the only factor related to hematological response [19 (6-61) ×10(9)/L vs 13.5 (5-45) ×10(9)/L, P=0.001] after 6 months therapy. After 12 months, the statistical differences were maintained, which were platelets baseline [18 (6-61) ×10(9)/L vs 10.5 (5-45) ×10(9)/L, P<0.001], absolute reticulocytes [0.03 (0.01-0.06) ×10(12)/L vs 0.029 (0.02-0.06) ×10(12)/L, P=0.043], transfusion-dependent of platelet (P=0.007) , transfusion-dependent of platelet and erythrocyte (P=0.012) . Multivariate analysis showed that platelets baseline could be an independent prognostic factor of hematological response (P=0.010 or 0.009) . Cutoff value of platelets by receiver operating characteristic curve was 15.5×10(9)/L. Conclusion: Baseline of higher platelets, higher reticulocyte, and no transfusion dependence of platelet are favorable prognostic factors. When platelets baseline is higher than 15.5×10(9)/L, CsA and androgen regimen is rational.

Objective To understand the prevalence and risk factors of Blastocystis hominis infection in inpatients in Jiangjin District, Chongqing City. Methods A cross-sectional study was conducted in a community hospital in Jiangjin District, Chongqing City, and the inpatients were surveyed by questionnaires. After obtaining the informed consent from the inpatients or legal guardians, the stool and blood samples were collected and examined by microscopy and PCR from April 17 to May 1, 2018. The univariate analysis and logistic regression analysis were used to analyze the risk factors of the B. hominis infection. Results A total of 198 hospitalized patients were investigated, and the infection rate of B. hominis was 10.61% (21/198), and the infection rate of the females (12.10%) was higher than that of the males (8.11%), but the difference was not statistically significant. The highest rate of infection was 19.23% in the age group of 10 to 20 years, followed by 17.74% in the age group of 60 years and above, and the lowest rate was 2.38% in the age group of 20 to 40 years. The difference in infection rates of B. hominis among the different age groups was statistically significant (P < 0.05). The infection rate of B. hominis in the people who used dry pail latrines was 33.30%, which was higher than that of the people who used water flush toilets (9.10%) (P < 0.05). The genotypes of B. hominis were ST1, ST3, ST6 and ST7, and ST6 and ST3 being the most predominant genotypes which accounted for 47.62% (10/21) and 38.10% (8/21) respectively, and among the infected males, the genotypes were only ST3 and ST6. The multiple logistic regression analysis showed that among the factors affecting B. hominis infection, only keeping pets was a risk factor [OR = 3.798, 95% CI (1.245, 11.581), P < 0.05]. Conclusion A high prevalence of B. hominis infection is found in the inpatients in Jiangjin District, Chongqing City, the predominant genotypes are ST6 and ST3, and keeping pets may be one of the main risk factors.

OBJECTIVE: To investigate the risk factors for brain injury in preterm infants by a multicenter epidemiological investigation of brain injury in hospitalized preterm infants in Anhui, China. METHODS: Preterm infants who were hospitalized in the department of neonatology in 9 hospitals of Anhui Neonatal Collaboration Network between January 2016 and January 2017 were enrolled as subjects. The data of maternal pregnancy and clinical data of preterm infants were collected, and the logistic regression model was used to analyze the risk factors for brain injury in preterm infants. RESULTS: A total of 3 378 preterm infants were enrolled. Of the 3 378 preterm infants, 798 (23.56%) had periventricular-intraventricular hemorrhage (PVH-IVH), and 88 (2.60%) had periventricular leukomalacia (PVL). Intrauterine distress, anemia, hypoglycemia and necrotizing enterocolitis (NEC) were risk factors for PVH-IVH (OR=1.310, 1.591, 1.835, and 3.310 respectively; P<0.05), while a higher gestational age was a protective factor against PVH-IVH (OR=0.671, P<0.05). PVH-IVH, NEC and mechanical ventilation were risk factors for PVL (OR=4.017, 3.018, and 2.166 respectively; P<0.05), and female sex and use of pulmonary surfactant were protective factors against PVL (OR=0.514 and 0.418 respectively; P<0.05). CONCLUSIONS Asphyxia/anoxia, infection/inflammation, mechanical ventilation, anemia and hypoglycemia may increase the risk of brain injury in preterm infants.

OBJECTIVE: To investigate the prevalence of obesity and sleep disorders and the association between them among children in Lanzhou, China. METHODS: The stratified cluster random sampling method was used to select 3 283 primary school students in four districts of Lanzhou of Gansu province. Physical examination and sleep questionnaire were conducted to screen out the children who met the criteria for sleep disorders or obesity as subjects. Among the 3 283 children, 200 healthy children without sleep disorders or obesity were enrolled as the control group. RESULTS: The prevalence rate of obesity among the 3 283 children was 5.76% (189/3 283). Among these 189 obese children, 80 (42.3%) had sleep disorders. The prevalence rate of sleep disorders was 16.24% (533/3 283), and the prevalence rate of obesity among the children with sleep disorders was 24.6% (131/533). Snoring was the most common sleep disorder in obese children. The prevalence rate of obstructive sleep apnea hypopnea syndrome was 45% (36/80) among obese children with sleep disorders. The obese children had a significantly higher prevalence rate of sleep disorders than the children with normal body weight [42.3% (80/189) vs 20% (40/200), P<0.01]. CONCLUSIONS There is a close relationship between obesity and sleep disorders in children in Lanzhou, China.

BACKGROUNDThe effects of near-road pollution on lung function in China have not been well studied. We aimed to investigate the effects of long-term exposure to traffic-related air pollution on lung function, airway inflammation, and respiratory symptoms.

METHODSWe enrolled 1003 residents aged 57.96 ± 8.99 years living in the Shichahai Community in Beijing. Distances between home addresses and the nearest major roads were measured to calculate home-road distance. We used the distance categories 1, 2, and 3, representing <100 m, 100-200 m, and >200 m, respectively, as the dose indicator for traffic-related air pollution exposure. Lung function, exhaled breath condensate (EBC) pH, and interleukin 6 levels were measured. As a follow-up, 398 participants had a second lung function assessment about 3 years later, and lung function decline was also examined as an outcome. We used regression analysis to assess the impacts of home-road distance on lung function and respiratory symptoms. As the EBC biomarker data were not normally distributed, we performed correlation analysis between home-road distance categories and EBC biomarkers.

RESULTSParticipants living a shorter distance from major roads had lower percentage of predicted value of forced expiratory volume in 1 s (FEV1% -1.54, 95% confidence interval [CI]: -0.20 to -2.89). The odds ratio for chronic cough was 2.54 (95% CI: 1.57-4.10) for category 1 and 1.97 (95% CI: 1.16-3.37) for category 2, compared with category 3. EBC pH was positively correlated with road distance (rank correlation coefficient of Spearman [rs] = 0.176, P < 0.001).

CONCLUSIONSLong-term exposure to traffic-related air pollution in people who live near major roads in Beijing is associated with lower lung function, airway acidification, and a higher prevalence of chronic cough. EBC pH is a potential useful biomarker for evaluating air pollution exposure.

The distribution, yield and sample information data of Pinus massoniana was obtained by document literature and sample investigation. Based on sample data from 12 provinces including 414 sample plots and environment factors in China,the distribution regionalization of P. massoniana was predicted by using Maxent and spatial analysis function of ArcGIS. The results showed that the northernmost distribution of P. massoniana was 33.5 degrees north latitude, and it mainly distributed in the southeast in China. Based on plant age, plant height, yield per plant and other growth index from 414 sample plots, combined vegetation form and other data, the growth regionalization of P. massoniana was carried out by using SPSS and related functions of ArcGIS. The results showed that Fujian, Guizhou and Guangxi had a lager distribution area of P. massoniana, meanwhile, it had a relatively higher yield of fresh pine needles. The relational model between environmental factors and shikimic acid,and procyanidin, and the total lignans was constructed by using SPSS regression analysis method. Then the spatial calculation function of ArcGIS was used tocarry out the quality regionalization of P. massoniana based on the relational model. The results showed that east of Sichuan, Guizhou, Chongqing had a good pine needles quality. Based on the distribution, growth and quality regionalization, the production suitability regionalization of P. massoniana was carried out. The results showed that the optimal planting base region mainly distributed in east of Sichuan, middle and east of Guizhou, and east of Guangxi.

BACKGROUNDThe nocturnal nondipping and elevated morning blood pressure (BP) in patients with obstructive sleep apnea syndrome (OSAS) have not yet been well investigated in Chinese patients. This study aimed to describe the BP profile, and to elucidate the relationships between daytime BP and nighttime BP, and between evening BP and morning BP in patients with OSAS.

METHODSTwenty teaching hospital sleep centers in China were organized by the Chinese Medical Association to participate in this study and 2297 patients were recruited between January 2004 and April 2006. BP assessments were made at four time points (daytime, evening, nighttime and morning) and polysomnography (PSG) was performed and subjects were classified into four groups by their apnea-hypopnea index (AHI): control, n = 213 with AHI < 5; mild, n = 420 with AHI ≥ 5 and < 15; moderate, n = 460 with AHI ≥ 15 and < 30; and severe, n = 1204 with AHI ≥ 30. SPSS 11.5 software package was used for statistical analysis and figure drawing.

RESULTSAll the average daytime, nighttime, evening and morning BPs were positively correlated with AHI and negatively correlated with nadir nocturnal oxygen saturation. The ratios of nighttime/daytime and morning/evening average BP were positively correlated with AHI. The ratio of nighttime/daytime systolic BP became a "reversed BP dipping" pattern until the classification reached severe, while the ratio of nighttime/daytime diastolic BP became reversed at moderate. Similarly, the ratio of morning/evening diastolic BP becomes reversed even at mild.

CONCLUSIONSOSAS may result in higher BP levels at all four time points. The ratios of nighttime/daytime and morning/evening BP increase with increased AHI. The increasing of diastolic BP, which is inclined to rise more quickly, is not parallel with increasing systolic BP.

OBJECTIVETo investigate the changes and the clinical significance of N-terminal pro-brain natriuretic peptide (NT-proBNP) and glycogen phosphorylase isoenzyme BB (GPBB) levels in neonates with asphyxia complicated by myocardial injury.

METHODSSixty-four neonates with asphyxia (39 mild, 25 severe) were enrolled. Of the 64 neonates, 30 had myocardial injury and 34 did not develop myocardial injury. Twenty-five healthy neonates served as a control group. Plasma levels of NT-proBNP and GPBB were measured using ELISA. Myocardial enzymes and cardiac troponin I were stimultaneously measured, and electrocardiography and chest radiographs were obtained.

RESULTSThe plasma levels of NT-proBNP and GPBB in neonates with myocardial injury were significantly higher than those in neonates without myocardial injury and in the control group (P<0.01). The neonates with severe asphyxia had significantly increased plasma NT-proBNP and GPBB concentrations compared to those with mild asphyxia and the control group (P<0.01). Spearman rank correlation analysis showed that plasma NT-proBNP level was positively correlated with plasma GPBB level in neonates with asphyxia. Plasma levels of NT-proBNP and GPBB were also positively correlated with plasma levels of CK-MB, CK and LDH (P<0.01).

CONCLUSIONSBoth NT-proBNP and GPBB can be used as biomarkers of myocardial injury in neonates with asphyxia. The measurement of plasma NT-proBNP and GPBB levels was useful in early identification of myocardial injury and severity evaluation in neonates with asphyxia.
