AIM: A capillary electrophoresis fingerprints(CEFP) method of Fructus Gardeniae was established to evaluate its quality. METHODS: The background electrolyte(BGE) was 25 mmol/L sodium borate solution containing 10% acetonitrile.The detection wavelength was 228 nm and 24 kV was applied.Fructus Gardeniae was extracted by water and injectded for 15 s(9 cm).Some parameters were used to evaluate the similarities.(RESULTS): 24 co-possessing peaks were selected as the fingerprint peaks of Fructus Gardeniae taking chlorogenic acid peak as the reference peak.The similarities between each of the ten places and the standard CEFP of Fructus Gardeniae were evaluated both qualitatively and quantitatively.The CEFP was also evaluated by the information index(I) and the relative information index(I_r). CONCLUSIONS: The CEFP has acceptable precision,reproducibility and can be used to control the quality of Fructus Gardeniae.

AIM: To establish a HPLC digitized fingerprints of Panax Ginseng rubra to control its quality. METHODS: The chromatographic fingerprints were determined by injecting 20 ?L of the sample solution each time on a Century SIL C_ 18 AQ column (20 cm?4.6 mm, 5 ?m) with the gradient elution solvent system composed of 0.1 mol/L NaH_2PO_4 aqueous solution-acetonitrile. The flow rate was 1 mL/min, the column temperature was maintained at (30?0.15)℃ and the signals were acquired at 203 nm. The chromatographic fingerprints were evaluated by both the chromatographic fingerprint index (F) and the information index of chromatographic fingerprint (I) and so on. RESULTS: 30 co-possessing peaks were selected as the fingerprint peaks and the similarities between each of the ten batches and the referential chromatographic fingerprints of Panax Ginseng rubra were calculated while taking adenosine peak as the reference peak. CONCLUSION: This method with good characteristics and specificity can be used in the quality control of Panax Ginseng rubra.

AIM: To develope a reversed-phase high performance liquid chromatographic method for the quantitative determination of chlorogenic acid and caffeic acid in Shegan Kangbingdu Injection. METHODS: The operation was carried out in the Kromasil ODS column with the mobile phase consisting of a mixture of water-methanol-acetonitril aceti acid(95∶10∶5∶2,v/v),in which the flow rate of 1.0 mL/min and UV detection wavelength at 326 nm were set to determine the contents of chlorogenic acid and caffeic acid. RESULTS: There were good linear relations between the concentrations and the peak-areas of chlorogenic acid and caffeic acid.The relative standard deviation of peak areas for chlorogenic acid or caffeic acid were 0.60%,0.32%,respectively.The two kinds of standard solutions were both stable in 16 h(RSD=0.54% for CGA,0.11% for CFA).The average recovery was 100.1%,99.6% for CGA,CFA,repectively.The detectable limit(S/N=3)was 0.012,0.020 mg/L,and the quantitative limit (S/N=10) was 0.037,0.052 mg/L,repectively. CONCLUSION:The method is simple,sensitive,rapid and accurate,and can be used for the quality control of Shegan Kangbingdu Injection

The pharmacological activity of Mycena dendrobii Fan et Guo, a new species of endophytic fungus was studied. It was revealed that the mycelia methanol extracts and the fermentation liquid ethanol extracts of Mycena dendrobii showed anglgesic effect to mice, which have the correlations to that of the traditional Chinese medicine ‘shihu’. The fermentation liquid ethanol extracts of Mycena dendrobii showed excitation effect to central nervous system of mice. Then the effective parts of anglgesic effect was determined.

Objective To prepare quercetin ( QUE) loaded chitosan nanoparticles ( CS-NPs), evaluate its physicochemical properties and antioxidation activity in vitro.Methods Quercetin chitosan nanoparticles were prepared by ionic crosslinking method and self-assembly method.The preparation method was optimized using entrapment efficiency (EE), drug loading (DL) and size as indexes.The best formulation and preparation conditions were optimized by orthogonal test based on single-factor test, evaluation indicator as particle size and EE.The physicochemical properties of the obtained QUE-CS-NPs were characterized by the following methods: the transmission electron microscope (TEM), dynamic light scattering (DLS) analysis for morphology, size distribution and Zeta potential.In vitro release behavior in 0.5% SDS solution was evaluated by dialysis tube method.In vitro antioxidant activity assays were performed by evaluating the abilities of the microspheres for hydroxide radicals and superoxide anions .Results TEM results revealed QUE-CS-NPs with round and uniform.Particle-size analysis showed that the diameters and Zeta potential of the QUE-CS-NPs were (282.9 ±20) nm and (30.5 ±2) mV, with uniform distribution (polydispersity below 0.185).DL and EE of QUE-CS-NPs were (8.81 ±0.65) %and (80.02 ±1.04) %, respectively.QUE-CS-NPs showed extended administration times with 66.2% cumulative release within 72 h.QUE-CS-NPs showed pronounced antioxidant activity and a concentration dependent, even more substantial than that of pure QUE.Conclusion QUE-CS-NPs show a good size, sustain release effect and pronounce antioxidant activity.

Objective To assess the value of quantitative color Doppler sonography in patients with systemic lupus erythematosus (SLE). Methods The right renal in 21 patients with SLE and 22 normal subjects were examined with Philips IU22 ultrasonic diagnostic device. Resistence index (RI) of interlobar artery and interlobular artery were measured with color Doppler sonography, vascularity index (VI), flow index (FI) and vascularization flow index (VFI) which reflecting the renal cortical blood flow were calculated with quantitated analysis software. All the parameters between two groups were compared and analyzed. Results The color signals of renal cortical blood flow in patients with SLE were inferior to those of the normal group, especially in the area near the edge of renal. No statistical difference of RI was found between the two groups (P>0.05), while VI, FI and VFI in SLE group were significantly lower than those of the normal group (VI, VFI, P<0.01, FI, P=0.01). Conclusion Color Doppler sonography combined with blood flow quantitative technique provide a helpful, sensitive and convenient tool to detecte the renal changes in SLE patients.

Objective To design and apply the nursing quality management system of our hospital in order to strengthen nursing informationization construction, and improve management efficiency of nursing quality. Methods Based on the original design of nursing management system, the quality management system which take nursing as the main part was researched and developed by us and applied to the clinical. Our nursing management department combined PDCA cycle with our nursing quality management, and developed nursing unit quality evaluation criteria, each ward were checked by evaluating group of nursing quality management, the analysis and corrective measures should be asked to put forward. Results From July to December in 2016, nursing accidents, pressure ulcer, tumbling, pipe slippage, medication, errors and all adverse events incidence compared with 2015 year dropped 60.00％(0.03/0.05), 43.33％ (0.13/0.30), 50.00％ (0.04/0.08), 40.00％ (0.04/0.10), 33.33％ (0.01/0.03),43.85％(0.25/0.57), and all adverse events in 2016 compared to the period of 2015 had statistically difference (χ2=7.266, P<0.05), and the problem rectification rate was significantly higher than before(χ2=-3.212--2.637,P<0.05).

Objective:To evaluate the effectiveness of interventional treatment for neonatal critical pulmonary stenosis(NCPS).Methods:Clinical data of 12 neonates with NCPS who received percutaneous balloon pulmonary valvuloplasty (PBPV) from January 2016 to December 2019 in Department of Cardiology, Shenzhen Children′s Hospital were summarized and analyzed.The collected data included transthoracic echocardiography (TTE), percutaneous oxygen saturation (SPO 2), relevant data on interventional surgery, and follow-up results. Results:All 12 neonates with NCPS received PBPV successfully.The postoperative pressure difference between the right ventricle and the pulmonary artery ranged from 8 to 35 mmHg[(20±7) mmHg, 1 mmHg=0.133 kPa]. The postoperative SPO 2 ranged from 74%-100%[(93.0±5.9)%]. Three neonates with NCPS received Blalock-Taussig (B-T) shunt.One neonate with NCPS developed supraventricular tachycardia during the operation.There was no death for these 12 neonates with NCPS. Conclusions:Interventional treatment of neonates with NCPS could achieve a better effect and be employed as the first treatment option.Some neonates with NCPS would require cardiac B-T shunt or patent ductus arteriosus stent implantation.
