OBJECTIVETo observe the impact of inducing the formation of the post-moxibustion sore on the efficacy of bronchial asthma treated with scarring moxibustion.

METHODSThree hundred and seventy-two cases diag nosed definitely as bronchial asthma at remission stage were randomly divided into a modified nursing group (248 cases) and a conventional nursing group (124 cases). The scarring moxibustion was applied at Dazhui (GV 14), Feishu (BL 13), Danzhong (CV 17) and Tiantu (CV 22) in either group. The direct moxibustion with moxa cone was adopted. In modified nursing group, 0.5% Iodine was used for the sterilization at moxa abscess. The herbal plaster was cut into an inverted triangle and compressed on the wound. After suppuration, the fester was not cleaned in each dressing change. Additionally, the patients were advised to have high-protein diets after moxibus tion till abscess dropped. In conventional nursing group, 0.5% Iodine was used for the sterilization at moxa abscess. The herbal plaster was cut into a round shape that could cover completely the moxa wound. After suppuration, in each dressing change, the wound was cleaned and sterilized. Additionally, the patients were advised to avoid any stimulating food after moxibustion till abscess dropped. The clinical efficacy, the change of C3 content in blood serum and the clinical symptom score were observed in two groups.

RESULTSThe total effective rate was 93.5% (232/248) in modified nursing group, which was better than 79.0% (98/124) in conventional nursing group (P < 0.01). C3 content increased apparently after treatment as compared with that before treatment in either group (both P < 0.01), but C3 level increased much more apparently in modified nursing group as compared with that in conventional nursing group (P < 0.01). The clinical symptom score reduced apparently after treatment in either group (both P < 0.01), but that reduced much more apparently in modified nursing group as compared with that in conventional nursing group (P < 0.01).

CONCLUSIONIn the treatment of bronchial asthma with scarring moxibustion, to induce the formation of the post-moxibustion sore achieves the better clinical efficacy as compared with conventional nursing.

Objective To compare the intubating conditions between dexmedetomidine and remifentanil when combined with sevoflurane-nitrous oxide (N2O) for anesthesia induction in the pediatric patients.Methods A total of 122 pediatric patients,aged 4-10 yr,of American Society of Anesthesiologists physical status Ⅰ,undergoing elective plastic surgery,were randomly divided into dexmedetomidine group (group D,n =61) and remifentanil group (group R,n=61).Eight percent sevoflurane and 60％ N2O were inhaled for induction of anesthesia,and the fresh gas flow was set at 6 L/min.After disappearance of eyelash reflex,dexmedetomidine 1 μg/kg and remifentanil 1 μg/kg were intravenously injected over 50-60 s in D and R groups,respectively,and 1 min later tracheal intubation was performed.The intubating conditions were graded,and the satisfactory intubating conditions and successful intubation were recorded.The development of adverse cardiovascular reactions and complications such as hyoxemia and laryngospasm before and after intubation and postoperative pharyngodynia was recorded.Results Compared with group D,no significant change was found in the success rate of intubation,rate of satisfactory intubation,intubating condition grade or incidence of postoperative pharyngodynia (P＞ 0.05),and the incidence of hypertension and sinus tachycardia after intubation was significantly increased in group R (P＜0.05).No pediatric patients developed hyoxemia,laryngospasn or sinus tachycardia in two groups.Conclusion When 8％ sevoflurane and 60％ N2O are inhaled for anesthesia induction,combing with dexmedetomidine 1 μg/kg produces better clinical efficacy than combing with remifentanil 1 μg/kg in improving the intubating conditions for pediatric patients.

OBJECTIVETo investigate the effects of glutamine enriched enteral feeding on immunoregulation in burn patients.

METHODSTwenty burn patients were randomly divided into enteral nutrition (EN) group and enteral immune nutrition (EIN) group, with 12 patients in each group. Patients in EN group received a standard enteral formula, while those in EIN group received an enteral formula enriched with glutamine after hospital admission. Nutritional support was continued for 10 days. Blood samples were obtained to determine plasma level of total protein (TP), albumin (ALB), prealbumin (PAB) and transferrin (TF) at 1, 4, 7, 10 post-burn days (PBD). At the same time the concentration of immunoglobulin (IgA, IgG and IgM) were determined, the percentage of CD3+, CD4+, CD8+ subpopulations of T lymphocytes, and the ratio of CD4+/CD8+ were determined by FCM.

RESULTS(1) There were no obvious difference of the plasma level of TP, ALB, TF, CD3+, IgM between the two groups at each time-point (P > 0.05). (2) The plasma PAB contents in EIN group were significant higher than that in EN group on 4 PBD [(90 +/- 14 vs 60 +/- 15) mg/L, P < 0.05], 7 PBD [(92 +/- 16 vs 64 +/- 13) mg/L, P < 0.05] and 10 PBD [(106 +/- 21 vs 72 +/-16) mg/L, P < 0.05]. (3) The percentage of CD4+ subpopulation and ratio of CD4+/CD8+ in EIN group were obviously higher than those in EN group on 7 PBD [CD4+ (55 +/- 5 vs 45 +/- 5)%, CD4+/CD8+ (1.92 +/- 0.31 vs 1.53 +/- 0.27)%, P < 0.05] and 10 PBD [CD4+ (56 +/- 5 vs 49 +/- 5)%, CD4+/CD8+ (2.36 +/- 0.36 vs 1.72 +/- 0.42), P < 0.05]. (4) The concentration of IgA and IgG in EIN group were markedly higher than that in EN group on 7 PBD [IgA (2.8 +/- 0.6 vs 2.2 +/- 0.5) g/L, IgG (12.1 +/- 1.3 vs 9.8 +/- 1.2) g/L, P < 0.05] and 10 PBD [IgA (3.1 +/- 0.6 vs 2.5 +/- 0.5) g/L, IgG (14.2 +/- 1.3 vs 10.4 +/- 1.3) g/L, P < 0.05].

CONCLUSIONThese findings suggest that glutamine enriched enteral feeding can improve nutritional status by promoting the synthesis of IgA, IgG, and increasing the PAB concentration, and corrected immunologic dysfunction in burn patients.

OBJECTIVE: To study the expression and significance of tight junction proteins (claudin-2, claudin-10, and claudin-17) in a mouse model of renal ischemia-reperfusion injury. METHODS: A total of 152 male C57BL/6 mice were randomly assigned to control group (n=8), sham-operation group (n=72), and model group (n=72). The renal pedicles at both sides were clamped for 30 minutes to establish a mouse model of renal ischemia-reperfusion injury. According to the time points of reperfusion (0, 3, 6, 12, 24, 48, and 72 hours and 5 and 7 days), the sham-operation group and the model group were further divided into 9 subgroups, with 8 mice in each subgroup. RT-PCR and immunohistochemistry were used to measure the mRNA and protein expression of claudin-2, claudin-10, and claudin-17 in renal tissue. RESULTS: The control and sham-operation groups had no significant changes in the mRNA and protein expression of claudin-2, claudin-10, and claudin-17 in renal tissue over the time of reperfusion (P>0.05). Compared with the control and sham-operation groups, the model group had decreased mRNA and protein expression of claudin-2 and claudin-10 after reperfusion, and the expression decreased gradually over the time of reperfusion, with the lowest levels at 24 hours of reperfusion (P<0.05). Compared with the control and sham-operation groups, the model group had increased mRNA and protein expression of claudin-17 after reperfusion, and the expression increased gradually over the time of reperfusion, with the highest mRNA level at 12 hours and the highest protein level at 24 hours of reperfusion (P<0.05). CONCLUSIONS Renal ischemia-reperfusion injury is closely associated with abnormal expression of tight junction proteins claudin-2, claudin-10, and claudin-17.

OBJECTIVETo investigate the effect of homocysteine (HCY) on activation of nuclear factor (NF-kappaB) and inhibitory factor IkappaB-alpha in human monocyte cell line THP-1, as well as its association with macrophage inflammatory protein (MIP-1alpha) upregulation.

METHODSTHP-1 monocytes were incubated with HCY, with and without NF-kappaB inhibitor pyrolidine dithiocarbamate (PDTC) pretreatment. Northern blot analysis and flow cytometry were used to detect MIP-1alpha mRNA and protein respectively. The nuclear protein NF-kappaB P65 subunit and the inhibitory protein IkappaB-alpha were analyzed by Western blotting.

RESULTSCompared with controls, HCY, at a concentration of 0.1 mmol/L, was able to enhance the expression of MIP-1alpha mRNA (up to 3.69-fold) and protein (1.16-fold) in THP-1 monocytes, as well as enhance NF-kappaB P65 transcription to nuclear proteins. These actions were significantly suppressed after pretreatment with 100 micromol/L PDTC for 30 minutes before HCY incubation; whereas incubation of THP-1 monocytes with PDTC only had no effect on both the expression of MIP-1alpha and nuclear transcription of NF-kappaB P65. Moreover, the level of IkappaB-alpha protein in THP-1 monocytes decreased after a 30-minute incubation with HCY, which gradually increased after 120 minutes.

CONCLUSIONSHomocysteine at a pathologic concentration stimulates MIP-1alpha expression in THP-1 monocytes, probably via NF-kappaB activation. Such activation may be caused by enhanced phosphorylation and degradation of the inhibitor protein IkappaB-alpha.

OBJECTIVETo explore the risk factors for coronary artery lesions (CAL) secondary to Kawasaki disease (KD) in children.

METHODSThe medical data of 895 children with KD were retrospectively reviewed. The patients were classified into two groups according to the presence of CAL: CAL (n=284) and control (n=611). The clinical and laboratory indices were compared between the two groups. The risk factors for the development of CAL in children with KD were identified by multiple logistic regression analysis.

RESULTSMale gender (OR=1.712), occurrence of non-CAL complications (OR=2.028), atypical KD (OR=3.655), intravenous immunoglobulin (IVIG) resistance (OR=2.912), more than 5 days of fever duration before IVIG treatment (OR=1.350), and increased serum procalcitonin (PCT) level (OR=1.068) were the independent risk factors for the development of CAL in children with KD (P<0.05), whereas increased serum albumin (Alb) level was a protective factor (OR=0.931, P<0.05). The areas under the receiver operating characteristic curve of serum PCT and ALB for prediction of the development of CAL in children with KD were 0.631 and 0.558, respectively.

CONCLUSIONSMale gender, atypical KD, occurrence of other non-CAL complications, long duration of fever and IVIG resistance are associated with an increased risk for CAL in children with KD. Serum PCT and ALB have little value in the prediction of CAL in children with KD.

BACKGROUNDOver 70% of the total tissue weight in the cartilage matrix consists of water, and the early-stage osteoarthritic cartilage is characterized by swelling. Water transport in the cartilage matrix and across the membranes of chondrocytes may be important in normal and pathological conditions of cartilage. The purpose of this study was to identify aquaporin-1 (AQP1) and aquaporin-3 (AQP3) expressions in the mandibular condylar cartilage after experimentally induced osteoarthritis (OA) in rats.

METHODSAn experimental temporomandibular joint OA was induced by partial discectomy in rats. The pathological characteristics of the normal, early-stage, and late-stage osteoarthritic TMJ cartilages were verified by histological techniques. The AQP1 and AQP3 gene expressions in the normal and osteoarthritic cartilages were measured using quantitative real-time reverse-transcription PCR analysis. The cartilage sections were incubated in primary polyclonal antibodies to AQP3; immunofluorescent microscopy was used to examine the AQP3 expression shown by its protein level.

RESULTSThe mRNA expression levels of AQP1 and AQP3, analyzed using quantitative PCR, revealed that AQP3 mRNA was highly up-regulated in the OA cartilage, which was considered significant. There was no notable difference in the expression of AQP1 mRNA between OA and normal controls. With the progressing of the OA, the localization of the AQP3 protein was quite different from that of the normal cartilage. Compared to the normal cartilage, the expressions of AQP3 protein were observed mainly in the proliferative zone and the upper mid-zone chondrocytes at the early-stage of OA, and were observed to appear frequently throughout the mid- and deep zone during the late-stage of OA.

CONCLUSIONSThe high expression of AQP3 mRNA in the OA cartilage and the different localization of the AQP3 protein suggest that it may play a particular role in OA pathogenesis. Further study of AQP3 function may provide new insight into the understanding of the molecular mechanisms underlying OA.
