Objective To explore the association of lipid metabolism and bomocysteine with hypertensive disorders in pregnancy and observe the inflammatory reaction and the pathological change of placenta.Methods We conducted a prospective randomized placebo-controlled study.Seventy-four cases with hypertensive disorders in pregnancy were recruited as the experimental group and 77 cases of normal pregnant women were recruited as matched control group from Aug.2008 to Mar.2010.The relationship between lipid metabolism and homocysteine was analyzed.Results There was significant difference between the two groups in body-mass index before pregnancy(29.03±4.52 vs.23.99±5.90,t =5.88),cholesterol[(6.16±1.48)mmol/L vs.(5.01±1.05) mmmol/L,t =5.52],low density lipoprotein[(3.46±1.35) mmol/L vs.(2.26±0.86) mmol/L,t =6.54]and C-reactive protein[(29.04±14.90) mmol/L vs.(15.48±4.57) mmol/L,t =7.62](P ＜ 0.05).No significant difference was found on triglycerides[(3.29±1.03) mmol/L vs.(3.49±1.37) mmol/L],high density lipoprotein[(1.84±0.40) mmol/L vs.(1.88±0.35) mmol/L],homocysteine [(8.77±2.65) mmol/L vs.(8.40±2.03) mmol/L]and neonatal weight[(3547±519)g vs.(3431±461)g](P ＞ 0.05).Significant difference exists in placenta pathology of infarction(54.55％ vs.31.04％),villi dysplasia,fit nodules form and hypoxia(65.46％ vs.39.66％)(P ＜0.05).Conclusion We should detect lipid,homocysteine and C-reactive protein by dynamic combinational ways,pay more attention to women with high BMI before pregnancy,and value placenta pathology research on hypertensive disorders in pregnant women.This has high clinical significance in revealing the etiology of hypertensive disorders in pregnant women and improving pregnant outcomes.

The aim of this study was to evaluate the seed quality of C.deserticola and establish quality grading rules of seeds by detecting the impacts of different processing methods on the contents of the effective components of C.deserticola for optimizing the suitable processing method.The seed quality was judged by thousand-kernel weight,empty embryo rate and water content.The samples were preliminary processed by freeze-drying,natural drying and hot air circulation drying respectively,and the content of phenylethanoid glycosides was determined by HPLC-UV.The seed quality classification standard of C.deserticola was established,and the seeds were divided into three grades based on the standard.It was found that freeze-drying method was optimum,featuring less effective component loss,beautiful appearance of herbal piece,crisp texture and fast drying.In conclusion,this study laid a foundation for the quality control of the seeds of C.deserticola with the provision of scientific evidence for the initial processing of the fresh product.

Objective To investigate the correlation between the insertion torque values and primary stability of dental implants using different insertion torque values ,and search for the best insertion torque values that can acquire good primary stability. Methods Six male pure beagles were selected, and the first molars and four premolars of bilateral mandibulars were extracted. Three months later, a total of 48 XIVE dental implants were inserted. All implants were divided into group A, group B, group C, and group D based on the insertion torque value (ITV): group A, 0 < ITV < 20Ncm; group B, 20 ≤ ITV < 40Ncm; group C,40Ncm ≤ ITV < 60Ncm;group D,ITV≥60Ncm The dental implant stability was measured by Resonance frequency analysis when implanrs were placed immediately. Results No complications occured.There was significant difference between group A and grop B (P=0.012), group A and grop C (P=0.037), group A and grop D (P=0.001). There are no ignificant difference among group B,group C and grop D(P>0.05). Conclusion With the limitations of the study, it was concluded the primary stability does not simply depend on the insertion torque;When the insertion torque value was no less than 20Ncm, the dental implant can acquire good primary stability.

Objective: To explore the effect of introducing multi-dimensional care strategy based on the concept of cognitive goal implementation in patients with femoral head necrosis replacement. Methods: From April 2016 to July 2018, 94 patients with femoral head necrosis were treated in Hainan Third People's Hospital. According to the digital table, the clinical subjects were named as study group and control group, 47 cases each. Among them, the control group carried out traditional intervention, while the research group carried out multi-dimensional care strategy based on the concept of cognitive goal implementation. The self-management ability, quality of life and satisfaction of the two groups were compared before and 4 weeks after the intervention. Results: After intervention, the scores of life behavior, rest and sleep, exercise, diet, medication compliance, self-monitoring, psychological counseling and regular reexamination in the study group were (2.0 ± 0.6), (1.9 ± 0.5), (1.8 ± 0.3), (2.0 ± 0.5), (2.4± 0.7), (2.0 ± 0.5), (2.1 ± 0.7) and (2.1 ± 0.6) respectively, which were higher than those in the control group (1.6 ± 0.4). There were significant differences in scores (t = 10.268-20.369, P<0.05). The scores of physiological function, physiological function, social function, mental health, emotional function, vitality, somatic pain and general health in the study group after intervention were (80.6 ± 6.5), (43.7 ± 4.2), (75.1 ± 6.1), (69.5 ± 5.1), (50.9 ±4.4), (66.5 ± 5.0), (79.3 ± 5.2) and (65.9 ± 6.0) respectively, which were higher than those in the control group (67.3 ± 4.2).) There were significant differences in scores (t = 11.803-18.277, P<0.05). The good rate of target implementation in the study group was 89.4% (42/47), which was higher than that in the control group (65.9% (31/47). The difference was statistically significant (χ² = 16.782, P<0.05). The nursing satisfaction of the study group was 97.9% (45/47), higher than that of the control group 85.1% (40/47). The difference was statistically significant (χ²=4.919, P<0.05). Conclusion Multidimensional care strategy based on the concept of cognitive goal execution can improve self-care ability and quality of life of patients with femoral head necrosis replacement, and improve patient satisfaction.

Objective To observe the changes and significance of the protein expression levels of nuclear factor-κB p65 (NF-κB p65), transforming long factor-β1 (TGF-β1) and apoptosis-related factors Bcl-2 and Bax in myocardial tissue of Bama miniature pig model of diabetic cardiomyopathy (DCM). Methods Ten healthy male Guangxi Bama miniature pigs, aged 4 to 5 months old, were selected and divided into control group and model group according to the random number table method, with 5 pigs in each group. After 12 hours of fasting in the two groups, the DCM model was replicated by intravenous injection of streptozotocin (STZ) 150 mg/kg; for the Bama miniature pigs in the control group, citric acid-sodium citrate buffer 150 mg/kg was injected intravenously. After 10 months of modeling, the basic conditions of the two groups of animals were observed and their fasting blood glucose (FPG) levels were detected. The protein expression levels of NF-κB p65, TGF-β1, Bcl-2 and Bax in myocardial tissue of two groups were detected by Western Blot and the pathological changes of myocardial tissue were observed under electron microscope. Results In the model group, 4 models were successfully established, and 1 died. The model pigs had symptoms such as polydipsia, polyphagia, polyuria and decreased body weight. The FPG level in the model group was significantly higher than that in the control group (mmol/L: 25.53±3.75 vs. 4.68±0.77, P < 0.01). Compared with the control group, the protein expression levels of NF-κB p65, Bax and TGF-β1 in the myocardial tissue of model group were significantly increased (NF-κB p65/GAPDH: 0.46±0.05 vs. 0.38±0.02, Bax/GAPDH: 0.46±0.01 vs. 0.35±0.01, TGF-β1/GAPDH: 0.39±0.01 vs. 0.33±0.01, all P < 0.05) and the expression level of Bcl-2 protein was significantly decreased (Bcl-2/GAPDH: 0.33±0.01 vs. 0.42±0.01, P < 0.01). Electron microscopy results showed that the myofibrils of myocardial tissue in the DCM model group were disordered, and the number of mitochondria in the gap was significantly reduced. A large number of mitochondria with vacuolar degeneration were observed. Conclusions The DCM model of Bama miniature pigs can be successfully replicated after 10 months of high-dose STZ disposable ear vein injection. The DCM model miniature pigs have obvious glucose metabolism disorder, and their myocardial tissue has inflammatory reaction, cardiomyocyte apoptosis and fibrosis.
