OBJECTIVE: To study the effect of various polarity fractions extracted from Sancaofang (SCF) and its combination on proliferation of human lung adenocarciaoma SPC-A-1 cells for bolting the most effective position of anti-tumor and suitable compatibility regimes.METHODS: Ethanol extraction and water extraction were adopted to prepare 95%,60% and 30% ethanol extract portion,water extract portion of SCF and compound decoction.The MTT assay was used to determine the effect of various polarity fractions of SCF,decoction and its combination on SPC-A-1 cells proliferation.RESULTS: IC50 of 60% ethanol extract was the smallest for SPC-A-1 cells.60% ethanol extract combined with 95% ethanol extract acts as a stimulus to anti-tumor activity significantly.CONCLUSION: The best suitable compatibility regimes were 95% ethanol extract combined with 60% ethanol extract.The liposolubility extract of SCF can be applied for anti-tumor.

OBJECTIVETo study the numbers and locations of spermatic veins, testicular arteries, and lymphatic vessels in the spermatic cord of the varicocele patient under the laparoscope.

METHODSFifty-seven varicocele patients received laparoscopic ligation of spermatic veins, during which we recorded the numbers and observed the locations of spermatic veins, testicular arteries, and spermatic lymphatic vessels.

RESULTSDuring the surgery, we identified 3.3 ± 1.2 spermatic veins, 1.4 ± 0.9 testicular arteries, and 4.3 ± 1.1 spermatic lymphatic vessels. No statistically significant differences were observed between the two side in the numbers of the spermatic veins, testicular arteries and spermatic lymphatic vessels (P > 0.05). The testicular arteries were seen on the exterior of the spermatic veins and winding around them, while the spermatic lymphatic vessels mostly between the veins.

CONCLUSIONThe spermatic veins, testicular arteries, and lymphatic vessels in the spermatic cord of the varicocele patient have their specific anatomic characteristics. Laparoscopic identification of these vessels may contribute to the surgical treatment of varicocele.

Objective To investigate the dynamic changes of MDA, NO, SOD and pathologic changes of the lung and kidneyduring repefusion after haemorrhagic shock in rabbits, and to study the protective effects of edaravone during thecourse.Method Totally 29 beparinized (3 mg/kg) rabbits were randomly divided into three groups:tho sham-operatedcontrol group (group C, n = 7), the haemorrhagic shock group (group I/R, n = 10), and the haemorrhagicshock group with edaravone infusion (group I/R-edaravone, n = 12). Rabbits in the latter two groups were bledfrom left arteria cmralis in 10 minutes with MAP maintained at 40 mmHg for 60 minutes, and then group I/R-edar-avone was given edaravone intravenously. After that, resuscitation began:all blood loss was replaced with normalsaline within 60 minutes with MAP at the end ≥ 70% MAP before haemorrhagic shock. Edaravone was reinjectedat 10 hours after shock.All rabbits were killed at 20 h after reperfusion.Plasma nitric oxide(NO), malonyldialde-hyde (MDA) and superoxide dismutase(SOD) in every group were measured before shock,60 minutes after shockaad 1 h, 5 h and 20 h after reperfusien. Part of the right lung and the right kidney tissues were taken from everyrabbit for pathologic examnation after sacrifice.Results There was no significant difference in MDA,NO aad SOD among three groups before shock. A higherlevel of MDA (5.35±0.29 μmol/L), NO(27.75 ±2.88 μmol/L)and lower serum concentration of SOD(194.58±14.42U/ml)could be found in group I/R during haemorrhagic shock,as compared to group C(4.44±0.59 μmol/L,25.01±4.95μmol/L,210.86±24.54U/ml,respectively,P<0.01).At 20 hours after resuscitation,MDA and NO contents continued to increase(5.69±0.24 μmol/L and 28.01±3.10 μmol/L respectively,P<0.05)while SOD contents kept decreasing(151.83±9.36 U/ml,P<0.05)in group I/R.Comparing to group I/R,group I/R-edaravone had significant lower level of MDA(3.48±0.23 μmol/L,P<0.01)and higher concentration of SOD(195.10±11.87U/ml,P<0.01).Edaravone attenuated the pathologic changes in the lung and kidney.Conclusions Edaravone could effectively protect vital organs from reperfusion injury caused by free radicals following haemorrhagic shock by reducing plasma levels of MDA,NO and increasing levels of SOD.

OBJECTIVETo investigate the effects of ethyl acetate extract of Huanglian Jiedu decoction (EAHD) on hyphae development of Candida albicans.

METHODInverted microscope, fluorescence microscope, SEM were applied to inspect the Morphological change of C. albicans treated by EAHD at different concentrations.

Objective To investigate the changes of gastric emptying in awake rats after acute myocardial infarction(AMI). Methods The male Wistar rats were submitted to thoracotomy followed by or not by occlusion of the left coronary artery. After 24 h, AMI(n=12)and sham groups (n=9)were fed in gavage(1 ml)with ~(99m)-Tc-DTPA labeled test meal. Half gastric emptying time (GET1/2) and 50min residual rate were measured by single photon emission computed tomography. The rats of AMI group were sacrificed after 50 min. Plasma level of motilin was measured by radioimmunoassay in AMI and sham group respectively(n=9). Results GET1/2 was significantly higher in AMI group[(23.1?4.7)min] than in sham group[(16.0?4.0)min](P

Objective To explore influence of long-term inhaled glucocoticoids(IGS) on soluble intercellular adhesion molecule-1(sICAM-1)) in children with bronchial asthma.Methods Enzyme-linked immunosorbent assay(ELISA) method was used to detect the serum sICAM-1 level in 36 healthy children and 29 children with bronchial asthma(untreated and post-treated for 3,6 and 12 months).Results 1.Serum sICAM-1 level was significantly elevated in children with asthma and significantly higher than that in normal control group(P

Objective To analyze the social and family factors influencing rehabilitation of mental retarded children.Methods 237 children diagnosed as mental retardation in 2004 in Beijing were researched with Self-designed Questionnaires and data were analyzed by Cross-tabs and Logistic Regression statistical method.Results The analysis showed that the degree of disabilities (P<0.001), education received (P<0.05), and the attitude from community to these children (P<0.05), were factors influencing rehabilitation of mental retarded children.Conclusion The degree of disabilities is the most important influencing factor to rehabilitation of mental retarded children; the mild or moderate mental cases can get good rehabilitation in a better community and family environment. The attitude to these children from community can make a great help to the rehabilitation.

OBJECTIVETo investigate the effect of andrographolide derivative Yanhuning (YHN) on Candida albicans biofilms in rats.

METHODThe rat C. albicans biofilms subcutaneous catheter model was established by intraperitoneally injecting YHN (40, 20, 10, 5, 2.5 mg x kg (-1)), with the FLC (80 mg x kg(-1)) positive group as the control group. After 7 d, CFU counting and XTT assay were used to evaluate the effect of YHN on C. albicans biofllms in vivo. Scanning electron microscopy (SEM) was applied to observe the morphological changes in rat biofilms intervened by YHN. The real-time fluorescence quantification PCR was adopted to detect expressions of C. albicans adhesion-related genes, such as ALS1, ALS3, HWP1, EAP1 and MP65.

RESULTThe YHN group showed much less CFUs on catheter pieces and lower XTT metabolic activity than the blank group, with dosage dependence. SEM also showed that YHN could obviously decrease C. albicans adhesion on subcutaneous catheters in rats. According to qRT-PCR's results, YHN can down-regulate expressions of ALS1, ALS3, HWP1, EAP1 and MP65.

CONCLUSIONYHN could inhibit C. albicans biofilms in rats.

Along with the increase in fungal infections, Candida albicans prevention and control become the focus of anti-fungal infection at present. This study aims to discuss the effect monomer andrographolide (AG) on C. albicans biofilm dispersion. In the experiment, micro-well plates and medical catheter pieces were used to establish the C. albicans biofilm model. It was discovered by XTT assay and flat band method that 1 000, 500, 250 mg x L(-1) AG could impact the activity of C. albicans biofilm dispersion cells. The morphological structures of residual biofilms on catheter pieces were observed with scanning electron microscopy, which showed that 1 000, 500, 250 mg x L(-1) AG could induce C. albicans biofilm dispersion in a dose-dependent manner, and the dispersed cells were dominated by the yeast phase. According to the real-time fluorescence quantification PCR (qRT-PCR) test, AG could up-regulate HSP90 expression and down-regulate UME6 and PES1 expressions. This study demonstrates that AG could induce C. albicans biofilm dispersion to some extent.
