Objective:To analyze the effect of MCT/LCT fat emulsions at different doses on the growth and development of prema-ture and low birth weight infants. Methods: Totally 76 cases of preterm or low birth weight infants were divided into the treatment group (40 cases) and the control group (36 cases), both groups were given MCT/LCT fat emulsions, amino acid and glucose injec-tions in 12-24 h after the birth. The initial dose of MCT/LCT fat emulsions in the treatment group was 2. 0 g·kg-1 ·d-1 and the dose was gradually increased to 3. 0 g·kg-1 ·d-1 with 0. 5 g·kg-1 ·d-1 progressive increase. The initial dose of MCT/LCT fat emulsions in the control group was 0. 5 g·kg-1 ·d-1 , and the dose was increased to 3. 0 g·kg-1 ·d-1 with 0. 5 g·kg-1 ·d-1 progressive in-crease. The treatment course was 7 days. The neonatal weight, serum total bilirubin, direct bilirubin, alanine aminotransferase, total cholesterol, triacylglycerol and blood glucose were monitored in the two groups. Results:The born body mass recovery time of the ob-servation group was (4. 38+0. 93) d, which was significantly shorter than that in the control group [(6. 81+1. 90) d]. After the re-covery, the body weight growth rate of the observation group was (30. 41+1. 81) g·kg-1 ·d-1 , which was significantly higher than that of the control group [(18. 21 +2. 08) g·kg-1 ·d-1, P <0. 05]. After the 7-day treatment, the blood biochemical indices showed no statistically significant difference between the two groups (P>0. 05). Conclusion:Early application of MCT/LCT fat emul-sions at high dose is beneficial to the improvement of nutritional status in premature infants.

To build the Dendrobium nobile -T2DM network, and elucidate the molecular mechanism of D. nobile to type 2 diabetes (T2DM). Collect the chemical composition of D. nobile and the targets on T2DM by retrieving database and documents, build the network of D. nobile to T2DM using the entity grammar systems inference rules. The molecular mechanism of D. nobile to T2DM includes: (1) regulating lipid metabolism by lowering triglyceride; (2) reducing insulin resistance; (3) protecting islet cells; (4) promoting the glucose-dependent insulin tropic peptide (GIP) secretion; (5) inhibiting calcium channel. Under the guidance of network pharmacology, through entity grammar systems inference rules we elucidate the molecular mechanism of D. nobile to T2DM, and provide the basis for the further development of health care products based on D. nobile.

OBJECTIVEThis study aims to investigate the effects of mineral trioxide aggregate (MTA) and calcium hydroxide on proliferation and differentiation of human pulp cells from primary and permanent teeth.

METHODSCell proliferation was detected by methyl thiazolyl tetrazolium (MTT) assay. The mRNA expression levels of dentinogenesis-related factors, including alkaline phosphatase (ALP) and dentin sialophosphoprotein (DSPP), and odontoclastogenesis-related factors, such as osteo- protegerin (OPG) and receptor activator of NF-κB ligand (RANKL), were determined by real time polymerase chain reac- tion (PCR).

RESULTSPrimary and permanent pulp cells treated with calcium hydroxide exhibited significantly lower proli- feration rates than the control cells (P<0.01). By contrast, the MTA-treated group showed significantly higher proliferation rates than the control group (P<0.01). Real time PCR results showed that calcium hydroxide-treated primary pulp cells exhi- bited significantly decreased ALP, DSPP, and OPG expression compared with the control group (P<0.01). Conversely, the MTA-treated group displayed significantly increased ALP, DSPP, and OPG expression (P<0.01). Calcium hydroxide-treated primary pulp cells also exhibited significantly upregulated RANKL expression (P < 0.01); by contrast, MTA-treated cells did not show any change in RANKL expression (P>0.05). Likewise, MTA-treated permanent pulp cells showed significantly upregulated ALP and DSPP expression (P < 0.01). However, the calcium hydroxide-treated group remained almost the same as the control group (P > 0.05). Neither MTA nor calcium hydroxide affected OPG and RANKL expression in per- manent pulp cells (P > 0.05).

CONCLUSIONMTA is more suitable as a pulp-capping agent, particularly in primary teeth, than calcium hydroxide.

Objective To analyze the constitution of in-patient death causes in Sharxi Cancer Hospital from 2005 to 2010. Method Statistical analysis of 1277 hospitalized cases from 2005 to 2010 in Shanxi Cancer Hospital was retrospectively conducted. Results The overall case fatality rate of hospitalized patients from 2005 to 2010 was 0.86 ％ (1277/146820),the rates were 1.16 ％,1.05 ％,0.99 ％,0.85 ％,0.84 ％, 0.64 ％, respectively, with a declining trend, and the differences among them was statistically significance (x2 =45.763,P ＜0.001).Total mortality rate of male hospitalized patients (1.26％) was higher than that of women (0.53％),and the difference was statistically significant (x2=215.367,P＜ 0.001).Analysis of cancer death cause revealed that lung cancer possessed the leading cause of cancer death with the ratio of 36.4％(456/1253). The analysis of top 10 death causes showed that the majority of the population in cancer death causes were men,cadres of staff and workers,secondary school education level people,and people over the age of 60. Conclusion The consitution of in-patient deaths in Shanxi Cancer Hospital is defined, which could provide a scientific basis for disease prevention and control.

Objective To explore the effect of positive end expiratory pressure (PEEP) on arterial oxygenation and intrapulmonary shunt during one-lung ventilation (OLV) and pulmonary function during perioperation. Methods Forty patients with normal pulmonary function,ASA I - II :scheduled for pulmonary lobectomy, were divided into control group and PEEP group by random digits table with 20 cases each. Patients were induced by double-lumen tubes under intravenous anesthesia and were received 10 ml/kg tidal volume, 12 frequents/min breathing rate during the two-lung ventilation (TLV), secondary reduced to 6 ml/kg tidal volume, 16-18 frequents/min breathing rate without PEEP (control group) or with 5 cm H2O cm H2O =0.098 kPa) PEEP (PEEP group) during OLV.Hemodynamics and respiratory mechanical parameters were continuously monitored, lung function before operation and at 72 h after operation was detected. Results Compared to before OLV,arterial oxygen tension (PaO2), arterial oxygen saturation (SpO2), oxygenation index (OI) were decreased and intrapulmonary shunt ratio (Qs/Qt) was increased in control group and PEEP group at 30 min after OLV (P < 0.01 or < 0.05). However,PaO2 and SpO2 and OI were higher and Qs/Qt was lower in PEEP group than that in control group at the same time point (P<0.05). In addition, FEV1%, FVC% and FEV1/FVC were (121.8 ± 25.0% ,(117.2 ± 24.3)% , (87.6 ± 15.7)%before operation and (84.9 ± 21.6)%, (77.2 ± 18.3)% , (70.5 ± 12.5)% at 72 h after operation respectively in control group, (116.9 ±24.5)% , (112.1 ±23.6)% , (85.3 ± 13.8)% before operation and (96.3 ± 20.4)%, (88.1 ± 19.8)% , (78.4 ± 10.2)% at 72 h after operation respectively in PEEP group. Although decreased in control group and PEEP group at 72 h after operation comparing with preoperation (P< 0.01 or < 0.05 ), FEV1%, FVC% and FEV1/FVC were higher in PEEP group than those in control group at 72 h after operation (P<0.05). Conclusion Appropriate PEEP increases arterial oxygenation,reduces Qs/Qt and improves pulmonary function during OLV,reduces the risk of hypoxernia and lung injury induced by OLV during perioperation.
