[Objective] To observe the therapeutic effect of pressing- moxibustion on Baihui (DU20) point combined with electroacupuncture (EA) on cervical spondylosis (CS) of vertebral artery type. [Methods] A single - blind random - controll trial was carried out in 34 cases of CS of vertebral artery type. The cases were randomized into two groups: the treatment group (Group A, n = 17) treated with pressing- moxibustion on Baihui point and EA on bilateral Fengchi (GB20) point and Jiaji (EX - B2) point of impaired vertebrae and the control group (Gropup B, n = 17) with EA alone. Plasma contents of thromboxane 82 (TXB2), 6-keto-prostaglandin Fl alpha (6-keto-PGF1?) and their ratio were measured before and after treatment. [Results] In the treatment group, 9 were cured, 6 markedly effective, 2 effective and 0 ineffective and 4,6,5 and 2 in the control group respectively; the markedly effective rate was 88.2% which was superior to that (58.8%) in the control group (P

Objective To explore the effect of bellybutton exposure on premature navel nursing effect.Method Three hundred and ninety-three premature infants were randomly divided into experiment group(n=195)and control group(198). Bellybutton fasciation and bellybutton exposure were used in the control group and the experiment group respectively. The two groups were compared in terms of umbilical shedding,time of umbilical healing,umbilical swelling,bleeding and breathing.Result The umbilical healing time in the experiment group was significantly shorter than that of the control group(P<0.05). The incidences of omphalitis,umbilical swelling and bleeding, changed breathing in the experiment group were significantly lower than those of the control group(all P<0.05).Conclusion The bellybutton exposure is effective in promoting the umbilical shedding in premature infants and reducing the incidence rate of premature navel infection.

Objective To investigate a method to detect the sentinel lymph nodes(SN) of thyroid papillary carcinoma and its predictive value for cervical metastasis of carcinoma. Methods Intraoperative methylene blue dye mapping was performed in 24 cases of thyroid papillary carcinoma. The coincidence rate of frozen section pathology and routine section pathology of SN was observed,and the predictive value of SN for (metastasis) of the cervical lymph nodes was noted. Results SN was successfully detected in 21(87.5%) of 24 cases. The average number of SN was 3 nodes. There was one false negative case, the false negative rate was 4.8%(1/24), and no false positive cases were found. The predictive value of sentinel lymph nodes to (cervical) lymph node metastasis was 83.3%.Conclusions Methylene blue staining to identify sentinel lymph nodes could accurately predict the status of cervical lymph node metastasis of thyroid papillary carcinoma.

Objective To determine the effect of lipoxins (LX) A4 and its agonist (BML-111) on the survival of RAW264.7 macrophage cells and TLR4/NF-κB signaling pathway. Methods RAW264.7 cells were treated with different concentrations of LPS, then the effect of LX A4 and BML-111 on the survival rate of these cells was observed. Cytotoxicity were detected by CCK-8 method and RT-PCR was used to detect the TLR4 and TRAF6 mRNA. The protein levels of TLR4 and pNF-κB p65 in RAW264.7 were determined by Western Blot. Results The survival rates of macrophage treated with LPS for 6 h in 1 000 ng/mL LPS in LX A4 group and BML-111 group were significantly higher than that in control group (P < 0.05). In the present of LPS, the TLR4 mRNA levels in RAW264.7 cells from LX A4 group and BML-111 group were significantly higher than those in the corresponding non-LPS groups. And the TRAF6 mRNA levels in each LPS stimulation group were higher than those in the corresponding non-LPS groups (P<0.05), while the protein level of TRAF6 in LX A4 and BML-111 groups were significantly lower than that in control group (P < 0.05). Stimulated with LPS, the protein levels of pNF-κB p65 in the LX A4 group and BML-111 group were all significantly lower than that in control group (P<0.05), and pNF-κB p65 expression level in control group was also significantly higher than the corresponding non-LPS groups (P < 0.05). Meanwhile, no significant difference was found between LX A4 and BML-111 group (P > 0.05). Conclusion LX A4 and BML-111 could inhibit the cytotoxicity of LPS on the RAW264.7 macrophage cells through the inhibition of the activation of TLR4/NF-κB signaling pathway, then reduce the inflammation. And this stable BML-111 may appear as another promising treatment for IBD disease.

AIM: To explore whether AT2 receptor is expressed in skeletal muscular vasculature, and the expression of angiotensin Ⅱ receptors in pulmonary circulation of children with left-to-right shunt but without obstructive pulmonary hypertension. METHODS: Lung and skeletal muscular tissue were obtained from 20 children with left-to-right shunt by biopsy during operation. These skeletal muscular tissues were detected by reverse transcriptase/polymerase chain reaction (RT-PCR ) and immunohistochemistry techniques for AT2 receptors. mRNA of AT1 and AT2 receptors in lung tissues were detected by RT-PCR and analyzed semi-quantitatively. RESULTS: In all of the skeletal muscular tissues, mRNA of AT2 receptor was found by RT-PCR, and the results of immunohistochemistry staining for AT2 receptor of vessels were positive. In the lung tissues, the level of mRNA of AT2 receptor was different to AT1 receptor, and the former was higher than the latter (P

Objective To detect fetal RhCcEe genotype from fetal DNA in maternal plasma for noninvasive prenatal diagnosis.Methods DNA from maternal plasma sample was extracted by use of QIAamp DNA Kit. The existence of fetal DNA was confirmed by amplified fetal SRY gene. The fetal RhCcEe gene was amplified by polymerase chain reaction (PCR) from 30 pregnant maternal plasma. The results of fetal RhCcEe genotype were evaluated retrospectively by the serologic analysis of infant and pregnant woman RhCcEe phenotype.Results Among the 30 samples, 13 were the same phenotypes between mother and infant, 17 were different. When mother phenotypes were RhCC, cc, EE and ee homozygous, the deleted allele gene can be successfully amplified from mother plasma.Conclusion Noninvasive fetal RhCcEe genotyping is reliable. When the mother was homogyzous, genotyping the fetal CcEe alleles was very significant and useful for HDN (hemolysis disease of newborn) diagnosis and therapy.
