Objective To search a new,simple,minimally invasive,safety and effective method to treat the cervical disc herniation.Methods 210 patients with cervical disc herniation received percutaneous nucleoplasty were evaluated.Results They were followed prospectively from two weeks to two months,fifty-nine patients improved significantly,the general clinical effective rate was 96.2%.No complication occurred.Conclusion The percutaneous nucleoplasty is an effective,rapid suited to outpatient,minimally invasive and safe procedure for cervical disc heriation.

OBJECTIVE:To observe the efficacy and safety of carboprost and Foley catheter for the expand cervix before hys-teroscopic electric resection. METHODS:80 patients with hysteroscopic operation were randomly divided into research group and control group. Research group was placed inside the vagina carboprost 1 mg 30 minutes before operation;control group was placed inside the Foley catheter 12 hour before operation. The relaxation degree of the cervix,average operative time,preoperative pain, postoperative morbidity and incidence of adverse reactions in 2 groups were observed. RESULTS:There were no significant differ-ences in the relaxation degree of the cervix,postoperative morbidity and incidence of adverse reactions between 2 groups(P>0.05). The average operative time and preoperative pain in research group were significantly better than control group,the differ-ence was statistically significant(P<0.05). CONCLUSIONS:Carboprost and Foley catheter have good efficacy and safety for ex-pand cervix before hysteroscopic electric resection,however,carboprost is better than Foley catheter in terms of average operative time and preoperative pain.

Objective To explore the relationship between children obesity and adiponectin(ADPN),leptin(LP),and high-sensitive C-reactive protein(hsCRP).Methods Seventy-one obese volunteers as obesity group and 30 normal volunteers who matched obese volunteers in age and sex as control group were selected from 13 702 children and adolescents of 2 to 18 years old in Xiangtan city by sampling survey.The body mass index(BMI),ADPN,LP,hsCRP,fasting blood-glucose(FBG),and fasting pure insulin(INS) were checked respectively.The homeostasis model assessment for insulin resistance(HOMA-IR) and the quantitative insulin-sensitivity check index(QUICKI) were calculated.The difference between the two groups was compared and the relationship of all indexes was analyzed.Results The values of ADPN and QUICKI in obesity group were significantly lower than those of control group(P

This study was designed to analyze the effect of the mitochondrial respiratory pathways of Candida albicans (C.albicans) on the biofilm formation.The 2,3-bis (2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide (XTT) reduction assay was used to measure the metabolic activities of biofilms formed by the C.albicans which were cultured in the presence of respiratory pathways inhibitors.The biofilms formed by the wide type (WT),GOA1-deleted (GOA31),GOA1-reconstituted (GOA32),AOX1a-deleted (AOX1) and AOX1b-deleted (AOX2) C.albicans strains were examined by the XTT reduction assay and fluorescence microscopy.The expression of adhesion-related genes BCR1,ALS1,ALS3,ECE1 and HWP1 in the biofilms formed by the above five C.albicans strains was detected by real time polymerase chain reaction.It was found that the metabolic activity of biofilms formed by C.albicans was decreased in the presence of alternative oxidase inhibitor whereas it was increased in the presence of classical mitochondrial respiratory pathway complex Ⅲ or complex Ⅳ inhibitor.AOX1 strain produced scarce biofilms interspersed with few hyphal filaments.Moreover,no significant changes in the expression of BCR1 and ALS3 were observed in the AOX1 strain,but the expression of ALS1 and ECE1 was down-regulated,and that of HWP1 was up-regulated.These results indicate that both AOX1 and AOX2 can promote the biofilm formation.However,AOX1a primarily plays a regulatory role in biofilm formation in the absence of inducers where the promoting effect is mainly achieved by promoting mycelial formation.

Based on Staphylococcus aureus 16S rRNA gene sequences,sequence comparisons have been applied to design a kind of stem-loop structured oligonucleotide probes whose loop sequence mismatched other bacterial strains 16S rRNA gene sequences in more than two positions with high specificity and sensitivity.According to the principle of molecular beacon technology and enzyme linked immunosorbent assay,a method has been evaluated using immobilized stem-loop structured oligonucleotides probe as the conformation switch which is applied to enzymatic detection of nucleic acid targets.As its specificity has been strengthened,the system is able to successfully eliminate false-positive result that is mismatch in an oligonucleotide.Employing a microtiter assay format,4ng of S.aureus 16S rRNA could be detected at least.This approach is more sensitive than other conventional method at least one order of magnitude.

In order to evaluate the characteristics of the spray drying of total flavonoids of Epimedium extracts assisted with soybean polysaccharide, a certain percentage of soybean polysaccharide or polyvidone were added to the total flavonoids of Epimedium extract to conduct the spray drying. The effect of soybean polysaccharides against the wall sticking effect of the spray drying was detected, as well as the powder property of total flavonoids of Epimedium spray drying powder and the dissolution in vitro behavior of the effective component. Compared with the total flavonoids of Epimedium spray drying powder, soybean polysaccharide revealed a significant anti-wall sticking effect. The spray drying power which had no notable change in the grain size made a increase in the fluidity, improvement in the moisture absorption and remarkable rise in the dissolution in vitro behavior. It was worth further studying the application of soybean polysaccharide in spray drying power of traditional Chinese medicine.

AIM: This study was designed to investigate the effect of ginsenoside Rg1 on the amyloid ?-protein precursor (APP) and neprilysin (NEP)expression induced by lipopolysaccharide (LPS) in C6 cell line in order to discover effectual Alzheimer's disease (AD)-treated drugs. METHODS: MTT colorimetric analysis was used to measure the survival rate of C6 cultured with ginsenoside Rg1 at different concentrations (2 5, 5, 10 and 20 ?mol?L -1) and LPS (100 mg?L -1). The expression of APP and NEP mRNA was measured by RT-PCR. RESULTS: LPS decreased the survival rate of C6, furthermore, the increase in APP expression and the decrease in NEP expression were observed. On the other hand, the above alteration induced by LPS was reversed by ginsenoside Rg1. CONCLUSION: This study demonstrates that LPS can cause cell damage, the increase in APP expression and the decrease in NEP expression. Ginsenoside Rg1 can exert a neuroprotective action, protect C6 cells against LPS-induced injury via inhibiting APP expression and increasing NEP expression.

AIM: To investigate the inhibitory effect of TanshinoneⅡA on U251 glioma cell line and its mechanism. METHODS: MTT was used to measure the levels of the proliferation in U251 cultured with TanshinoneⅡA at different concentrations. The effects of TanshinoneⅡA on cell cycle of U251 were observed by FCM. The expression of proto-oncogene c-myc was measured by RT-PCR. RESULTS: The proliferation of U251 was obviously inhibited by TanshinoneⅡA in a dose dependent manner. The inhibitory rate came to the peak at (54 2?0 9)%, when cultured with TanshinoneⅡA at 0 10 g/L. The outcome of FCM showed that the proportion of G 0/G 1 phase cells was increased and the proportion of S phase cells was reduced obviously, when cultured with TanshinoneⅡA at 0 10 g/L for 3 days. The RT-PCR experiment showed that the expression of proto-oncogene c-myc was notably decreased, when the dose of TanshinoneⅡA was increased. CONCLUSION: TanshinoneⅡA inhibited the proliferation of U251 and the expression of proto-oncogene c-myc.
