Objective To investigate the feasibility of 18G trocar for central venous catheterization in adults.Methods Retrospective analyzed the clinical data of 60 patients with central venous catheterization under local anesthesia.These patients were randomly divided into the control group and the observation group.Selected the internal jugular vein as the site of the puncture catheter.The control group was punc-tured by conventional puncture needle while the observation group was punctured by the 18G trocar.Results There was no statistical differ-ence between the two groups in the success rate of final puncture and catheterization(P>0.05).Compared with the control group,the suc-cess rate of guidewire insert was higher,the puncture operation time was shorter,the pain score during puncture operation was lower,and post-operative patient satisfaction was higher in the observation group.The differences of the two groups were statistically significant(P<0.05). Conclusion 18G trocar can perform central venous catheterization successfully.This method has great advantages for awake patients,and it also worked in some cases with difficult wire insertion.

OBJECTIVETo promote a new kind of alternative needle of filiform-fire needle with fire needle.

METHODSThe common three-headed fire needle, thick fire needle, less-thick fire needle, fine fire needle, single-filiform needle and three-filiform-needle were used by 20 medical staffs, and the time of heating needles was recorded. The advantages of using filiform needles compared with common fire needles were evaluated.

RESULTSThe time of heating single and three-filiform needles was shorter than the other four common fire needles (all P < 0.01).

CONCLUSIONFiliform needle is better than the common fire needle in terms of production process,materials, and heating time, etc. Therefore, filiform needles can replace common fire needles for pricking.

OBJECTIVETo study the prognosis and the factors affecting the prognosis in children with acute respiratory distress syndrome (ARDS).

METHODSSeventy-eight children with ARDS were enrolled. The states of their survival within 30 days were followed-up.

RESULTSOf the 78 children with ARDS, 51 cases demised, 27 cases survived, with a 30-days survival rate of 35%. The average survival time was 14.4 days (median: 8 days). The peak of death appeared within 3 days after ARDS. There were significant differences in aspects of age, primary disease, percentage of neonatal hyaline membrane disease, pediatric critical illness score (PCIS), duration of mechanical ventilation, oxygenation index (PaO(2)/FiO(2)), white blood cell count and number of involved organs between the died and survived children (P<0.05 or 0.01). The Cox multiple factors analysis showed that the age (HR 3.924~3.938), primary disease (HR=1.817) and PCIS (HR=0.469) were the risk factors of death.

CONCLUSIONSThe peak of death usually appears within 3 days after ARDS. Age, primary disease and PCIS are the independent factors of prognosis in children with ARDS.

Objective To summarize the treatment principle of acupuncture-moxibustion in treating Bi-impediment syndrome from the application rules of meridians and acupoints in Ming-Qing Dynasties by sorting out and analyzing the Chinese medicine literatures about acupuncture-moxibustion for Bi-impediment syndrome in Ming-Qing Dynasties, for providing literature evidence for basic and clinical research of Bi-impediment syndrome.Method Via electronic retrieval ofZhong Hua Yi Dian (Zhen Jiu Tui Na Lei) (Chinese Medical Encyclopedia,Chapter of Acupuncture-Moxibustion and Tuina), the data related to Bi-impediment syndrome in Ming-Qing Dynasties were extracted to establish a database categorized by meridians and acupoint features in Excel for analysis.Result There were 267 items of records about acupuncture-moxibustion in treating Bi-impediment syndrome in Ming-Qing Dynasties, involving the fourteen ordinary meridians, and 131 acupoints including 5 extra points; the frequency of using the Gallbladder Meridian ranked the top, followed by the Large Intestine Meridian; points from the Bladder Meridian were predominant, followed by the Gallbladder Meridian; there were 28 commonly-used acupoints (frequency>5), which were Quchi (LI 11, 26 times), Huantiao (GB 30, 23 times), Hegu (LI 4, 22 times), Chize (LU 5, 16 times),Yanglingquan (GB 34, 15 times), and Weizhong (BL 40, 14 times). Of the specific acupoint, the five Shu points were most frequently used, with a frequency of 217.Conclusion In the treatment of Bi-impediment syndrome with acupuncture-moxibustion, doctors in Ming and Qing Dynasties selected yang meridians more often than yin meridians, and Gallbladder, Large Intestine and Bladder Meridians had comparatively higher frequencies; regarding the application of acupoints, the specific acupoints were often used, especially the five Shu acupoints. The study results provide reference for acupoint selection in the treatment of Bi-impediment syndrome with acupuncture-moxibustion.

OBJECTIVETo elucidate intracellular signal pathway in formation of multidrug resistance (MDR) of hepatocellular carcinoma (HCC) induced by its microenvironment, and to explore the potential role of extracellular signal-regulated kinase/mitogen-activated protein kinase (ERK/MAPK) pathway in this process.

METHODSActivity of ERK/MAPK was examined by Western blot technique through comparing the ratio of phosphorylation of ERK/MAPK to total ERK/MAPK protein in HepG2 cells exposed to hypoxia, low glucose or transfected by plasmid pcDNA3/HBX. After being treated by the specific ERK/MAPK pathway inhibitor U0126, Western blot technique was used to analyze the alterations of the expression of P-gp, MRP1, LRP and HIF-1alpha at protein level. RT-PCR was used to analyze the alterations of the expression of HIF-1alpha mRNA. Cellular location of HIF-1alpha protein was determined by immunocytochemistry after being treated by U0126.

RESULTSThe activations of ERK/MAPK determined by the ratio of phosphorylated ERK/MAPK to the total ERK/MAPK were increased in varying degrees in HepG2 cells respectively exposed to different microenvironment. After being treated by U0126 for 12 h, the expressions of mdr1, MRP1, LRP genes and protein in those cells were decreased to some extent. However, the gene expression of HIF-1alpha was not influenced and only its protein was decreased. HIF-1alpha protein was reversely translocated into cytoplasm from nucleus after being treated by U0126.

CONCLUSIONSERK/MAPK pathway is involved in the course of the formation of MDR of HCC induced by microenvironment.

[Objective]To investigate the characteristics of immunophenotypes in hepatocellular carcinoma(HCC) before liver transplantation.[Methods]The immunophenotypes of T-,B- cells,monocytes,dendritic cells(DC)and NK-cells in peripheral blood from 6 HCC patient who were ready to have liver transplantation and 6 healthy volunteers were analyzed by multicolor flow cytometry.[Results]In the patients,the proportions of CD4+PD-1+T cells,Treg cell (CD4+CD25+CD39+T cells),CD19+B cells,Plasmablasts(CD27highCD38highIgD-IgM-),classical monocytes(CD14high CD16-)and mature NK-cells(CD3-CD56high)were all higher than those in the healthy controls(all P<0.05).However, marginal zone B cell(CD27+IgD+),Non-switched B cells(CD27+CD38dimIgM+),intermediate monocytes(CD14high CD16+)and immature NK-cells(CD3-CD56+)were lower than those in the healthy controls(all P<0.05). And there wasn't any obvious difference in quantity being observed among other cell types.[Conclusion]There was difference in the immunophenotypes of immune cells in peripheral blood between HCC patients before liver transplantation and healthy people.And this finding exerts important effects on monitoring the immune status of the patients after liver transplantation and guiding the administrations of immunosuppressors.

OBJECTIVETo compare efficacy differences between fire filiform needle combined with mild moxibustion and gabapentin combined with sham acupuncture for postherpetic neuralgia (PHN).

METHODSOne hundred cases of PHN were randomly divided into a needle group and a medicine group, 50 cases in each one. In the needle group, pricking method of fire filiform needle was given at the Ashi points, and then mild moxibustion was applied for 15 min. In the medicine group, the oral administration of gabapentin capsule and sham acupuncture at non-acupoints in the distal end of lesions were applied. The treatment was required for 21 days in both groups. The visual analogue score (VAS) was recorded before treatment and on the 1st day, 2nd day, 3rd day, 6th day, 9th day and 12th day of treatment. The most severity of pain within last 24 h, preset severity of pain, immediate analgesia effect and starting time of pain relief were observed, also the efficacy was assessed and improvement of symptoms was observed in the follow-up visit.

RESULTSThe total effective rate was 94.0% (47/50) in the fire filiform needle group, which was superior to 86.0% (43/50) in the medicine group (P < 0.05). Compared with medicine group, the VAS of the most severity of pain within last 24 h was obviously reduced after the 2nd treatment in the fire filiform needle group while that of present severity of pain was relieved after the 1st treatment (both P < 0.05). The immediate analgesia effect in the fire filiform needle group was obviously superior to that in the medicine group in the first three times of treatment (all P < 0.05). The average time of pain relief was (3.91 +/- 0.82) days in the fire filiform needle group, which was significantly earlier to (6.53 +/- 1.13) days in the medicine group (P < 0.05). 26 cases were cured in the fire filiform needle group in the follow-up visit, which was superior to 2 cases in the medicine group (P < 0.05). The improvement of VAS, pain range and sleep quality in the needle group were also superior to those in the medicine group (all P < 0.05). The direct medical cost in the fire filiform needle group was (232.32 +/- 48.108) yuan, which was significantly lower than (466.00 +/- 41.09) yuan in the medicine group (P < 0.05). There was only one case of adverse effect in the medicine group during the treatment.

CONCLUSIONThe fire filiform needle combined with mild moxibustion could obviously relieve the pain in PHN patients, which has superior immediate analgesia effect and pain relieving time compared with gabapentin, which also has less adverse effects and cheap cost.

OBJECTIVETo evaluate four therapeutic measures on acute tetramethylene disulphotetramine (TETS) poisoning and the effects of it on intelligence of children.

METHODSAll 86 patients of acute TETS poisoning were randomly divided into 4 groups (the control group, sodium valproate group, sodium dimercaptopropane sulfonate group and the hemoperfusion group). The therapeutic effects were observed after the arranged treatment was administrated. According to age, residence, sex, education and domestic economy, 30 children were matched by 1:1 with children of TETS poisoning.

RESULTSThe termination time of seizure, doses of diazepam, mental symptoms and the continual time of mental symptoms were not significantly different among these three groups. After hemoperfusion, the seizure of patients was terminated or the frequency was obviously decreased, but the level of TETS in blood was not reduced. The average scores of full intelligence quotient (FIQ), the verbal intelligence quotient (VIQ) and the performance intelligence quotient (PIQ) of children in poisoning group were 9.1, 8.8 and 7.7 less than the controls. The average scores of FIQ of children with bad state were 15 less than the controls.

CONCLUSIONTherapeutic effects of sodium valproate and sodium dimercaptopropane sulfonate on acute TETS poisoning should be not better than using diazepam and sodium phenobarbital. Therapeutic effects of hemoperfusion on TETS poisoning is good. TETS poisoning should have a great influence on intelligence of children.

OBJECTIVETo explore the establishment of the mimetic aging effect in guinea pigs induced by D-galactose, and to detect the biological indicatrix associated with hearing loss and provide a new tool for molecular pathogenesis of hearing loss.

METHODSTotal of 51 guinea pigs were randomly divided into three groups: group A (model aging group, n = 25), which were injected with D-galactose (200 mgxkg(-1)xd(-1)) by intra peritoneum for 6 weeks, group B (model control group, n = 18), which were given the same amount of saline only, and group C (vacant group, n = 15) were not treated. Then, The guinea pigs in group A and B were exposed in noise for 8 days, 8 hours once a day. Auditory brainstem response (ABR) was used to test the hearing threshold of guinea pigs thrice, first before the drug administered, then after 6 weeks the drug used, third after noise exposure. And colorimetry was used to analyze the activity of superoxide dismutase (SOD) and malon dialdehyde (MDA) in brain and liver tissue. The DNA of inner ear tissue was harvested and amplified fragment length polymorphism (AFLP) was used to detect the differential polymorphic markers.

RESULTSAfter injection, there was no significant difference in elevation of ABR threshold between the group A and group B (t = 1.14, P > 0.05). However, exposure of noise later, elevation in ABR threshold of (22.97 +/- 10.56) dB peSPL was observed in group A, and (14.16 +/- 7.36) dB peSPL in group B. The was significant difference in variation of hearing threshold between group A and group B (t = 2.78, P < 0.05). The activity of SOD in brain and liver tissue in group A was lower than that in group B. the level of MDA was opposite between group A and group B. The difference between group A and group B was significant (P < 0.01). A differential polymorphic marker was observed by AFLP.

CONCLUSIONSThe mimetic aging effect of the guinea pigs can be induced by D-galactose, and this model can not directly induce the hearing loss. The differential polymorphic marker possibly act as a predisposing factor which can greatly enhance the sensitivity of the ear to the noise.

Objective:To study the soil physical and chemical properties， microorganisms， and metabolites in different culture environments of Gastrodia elata， so as to provide scientific basis for subsequent cultivation of G. elata in multiple environments. Method:The tubersphere soil of G. elata cultured in different environments was collected for analyzing the soil nutrients， microbial numbers， and metabolite differences using the agrochemical method， plate-count method， and gas chromatography-time-of-flight mass spectrometry （GC-TOF-MS）-based non-targeted metabonomic approach. Result:The analysis of soil physical and chemical properties revealed the highest soil moisture， pH， available potassium， and available phosphorus in the spinney and the highest electrical conductivity， total nitrogen， alkali-hydrolyzable nitrogen， and organic matter in the pinewood. As demonstrated by the quantitative analysis of soil microorganisms， the cultivable microorganisms were bacteria， actinomycetes， and fungi， with the bacterial population and total microbial biomass in the spinney and the number of fungi and actinomycetes in the barren slope detected to be the largest. The ratio of bacteria to fungi （B/F value） in the pinewood was the highest， while that in the barren slope was the lowest. The results of metabonomic research demonstrated that the compositions and quantities of soil metabolites in the spinney （Z group）， pinewood （S group）， and barren slope （HD group） varied. Through comparisons between S and Z groups， between HD and Z groups， as well as between HD and S groups by orthogonal partial least squares discriminant analysis （OPLS-DA）， 18， 35， and 24 differential metabolites were separately screened out， and the Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analysis yielded 5， 9， and 13 metabolic pathways. There existed a significant causal relationship of the soil physical and chemical properties and microbial numbers with the metabolites. Conclusion:The soil physical and chemical properties， microbial numbers， and metabolite changes differed significantly in different culture environments of G. elata， which were sorted by the suitability in a descending order as follows： spinney > pinewood >barren slope. The soil physical and chemical properties and microbial numbers are the crucial factors driving changes in soil metabolites， suggesting that regulating the soil physical and chemical characteristics and microbial characteristics in the culture environment is an important mechanism for maintaining the G. elata-soil-microbial symbiotic system.
