Objective To identify and rename one strain stored in National Center for Medicine Culture Collections ( CMCC) and used for tracheitis vaccine production. Methods The test strain CMCC (B)29108 and the type strain DSM30007T were cultured on NA medium. Characteristics in morphology, physiology, biochemistry and fatty acid profile were compared between the two strains. Phylogenetic analysis was based on 16S rRNA and rpoB gene sequences, together with the DNA-DNA hybridization assay. Results A Comparative analysis of a partial sequence of the 16S rRNA gene sequence revealed that the CMCC( B) 29108 strain was closed to the Acinetobacter species and showed the highest similarity with the type strain Acinetobacter baumannii DSM30007T. Moreover, the CMCC(B)29108 strain was highly similar to type strain DSM30007T in morphology, physiology, biochemistry and fatty acid profile. On the phylogenetic tree based on 16S rRNA and rpoB gene of all Acinetobacter members, the CMCC(B)29108 strain steadily clustered into one independent branch only with the DSM30007 T strain with a DNA-DNA hybridization value of 100%. Conclusion The CMCC(B)29108 strain that is one of the strains used for the production of tracheitis vac-cine should be assigned to the species of Acinetobacter baumannii based on its phenotypic, phylogenetic and chemotaxonomic characteristics.

Objective Henoch-Sch?nlein purpura(HSP)is a common multisystemic vasculitis in children ,but the exact pathogenesis remains unknown. Pentraxin 3(PTX3),a new kind of inflammatory cytokines,has a strong inflammatory effect,and is involved in occurrence and develop-ment of a variety of autoimmune diseases. The objective of this study is to evaluate the expression of PTX3,interleukin-8(IL-8),tumor necrosis fac-tor-α(TNF-α)and high sensitivity C-reactive protein(hs-CRP)in children with HSP,and explore the clinical significance of PTX3 in HSP devel-opment. Methods Thirty-six children(HSP group)and 17 healthy children(control group)were enrolled in the study. Serum levels of PTX3,IL-8 and TNF-α were detected by enzyme-linked immunosorbent assay. Serum hs-CRP levels were measured by automatic biochemical analyzer. Re-sults The serum levels of PTX3,IL-8,TNF-α,and hs-CRP were up-regulated in HSP group compared with the control group(P<0.05). The levels of PTX3,IL-8,TNF-α,and hs-CRP in patients with joint symptoms,or/and gastrointestinal symptoms,or/and kidney injury were significant-ly higher than those patients without joint symptoms,or/and gastrointestinal symptoms,or/and kidney injury(P<0.05). The expression of PTX3 was positively correlated with the expression of IL-8 and TNF-α(r=0.514,0.833,all P<0.05),but there was no correlation between PTX3 and hs-CRP(r=0.292,P>0.05). The expression of PTX3,IL-8,TNF-α and hs-CRP in HSP patients had no gender difference(all P>0.05). Con-clusion The high expression of PTX3 is related to the degree of inflammation in children with HSP. The up-regulated expression of PTX3 may play an important role in pathogenesis of HSP in children.

As one of the important founders of GAO's acupuncture academic school in YanZhao area, Professor GAO Yuchun 's experience of acupuncture for headache is summarized in this paper. In the opinion of Professor GAO, the treatment of headache should focus on eliminating evil and relieving pain, and the syndrome differentiation should be based on meridian differentiation, especially on three yang meridians of foot as well as liver meridian and kidney meridian. In the acupoint prescription, attention should be placed on strengthening the spleen and stomach. The midnight-midday ebb flow acupuncture is advocated. The combination between acupuncture order and movement of qi is emphasized. In the manipulation, the role of pressing hand, the stimulation during reinforcing and reducing methods, and needle-retention time are important. The breathing reinforcing and reducing method of acupuncture are also advocated.

Objective: To observe the difference of the effect of low-frequency electroacupuncture (EA) on blood lipids between male and female patients with simple obesity due to damp induced by spleen deficiency. Methods: Eighty patients with simple obesity were recruited, including 37 males and 43 females, to receive low-frequency EA by selecting Yinlingquan (SP 10), Sanyinjiao (SP 6), Zusanli (ST 36), Fenglong (ST 40), Quchi (LI 11), Tianshu (ST 25), Zhongwan (CV 12), Shuifen (CV 9), Qihai (CV 6) and Guanyuan (CV 4), with needles retained for 30 min. The treatment was given once a day, 10 sessions as a treatment course, for 2 courses in total. The contents of body fat percentage (F%), total cholesterol (TC), triglyceride (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), blood glucose (Glu) and adiponectin (ADPN) in serum were observed to see the changes, and the two groups were compared and analyzed. Results: After the treatment, F%, and serum contents of TC, TG, LDL, Glu and ADPN dropped significantly in the two groups (P<0.05 or P<0.01) and the serum content of HDL increased significantly in male group (P<0.05). The decrease of F% in female group was more significant than that in male group (P<0.01); the decrease of ADPN in male group was more significant than that in female group (P<0.05). Conclusion: EA can regulate the disordered blood lipids in male and female patients with simple obesity, with certain differences between genders. The decrease of subcutaneous fat content is more significant in females than that in males, while the decrease of ADPN is more significant in males.

OBJECTIVETo compare the therapeutic effects between the Hwato neuro and muscle stimulator (SXDZ-100) and the regular electronic stimulator (SDZ-II) on chronic functional constipation.
METHODSSixty-four cases of chronic functional constipation were randomly divided into a (SXDZ-100) observation group (n = 33) and SDZ-II control group (n = 31). For the SXDZ-100 group, under the considerations of patients' endurance, Zhigou(TE 6) and Tianshu (ST 25), Zusanli (ST 36) and Shangjuxu (ST 37) were punctured and then the courle of acupoints on the same side were connected with SXDZ-100 apparatus in reinforcing and reducing by twirling and rotating manipulation wave for 30 min, while in the control group SDZ-II apparatus was applied in the same way mentioned above with disperse-dense wave at frequency of 1Hz/20Hz for 30 min. By means of clinical therapeutic effect evaluation and clinical symptom score, the contrast between two groups can be made.
RESULTSAlthough the total effective rates were both 100.0%, the rate of short term effects in SXDZ-100 group (54.6%, 18/33) is significantly higher than that in SDZ-II group (29.0%, 9/31) (P < 0.05). After the treatment, the clinical symptom scores in both groups decreased significantly (both P < 0.05). And the therapeutic effective indices of the SXDZ-100 group were significantly higher than those of the SDZ- II group (P < 0.05).
CONCLUSIONThe therapeutic effect of Hwato neuro and muscle stimulator (SXDZ-100) on chronic functional constipation is superior to that of a regular electronic stimulator (SDZ-II).

Objective: To investigate the effect of moxibustion at Shenque (CV 8) on fatigue in rats with chronic exercise-induced exhaustion. Methods: Thirty male Sprague-Dawley (SD) rats were randomly divided into a blank group, a model group and a moxibustion group, 10 rats in each group. Except rats in the blank group, the remaining rats were subjected to create long-term exhaustion models by repeated swimming. After successful modeling, rats in the moxibustion group received mild moxibustion at Shenque (CV 8) for 15 min, once every other day with a total of 10 times. Rats in the model group and the blank group did not receive moxibustion. At the end of the treatment, the exhausted times, and the body weight of rats before and after the experiment were compared among groups. The levels of blood malondialdehyde (MDA) and urea nitrogen (BUN), as well as the activities of aspartate transarninase (AST), alanine aminotransferase (ALT) and lactate dehydrogenase (LDH) were also measured by the automatic biochemical analyzer, 24 h after the exhausting excise. Results: The 10th swimming time was significantly longer in the moxibustion group than that in the model group (P<0.01). The increase rate of the body weight was lower in the rats of the moxibustion group than that in the model group before the 7th and the 10th exhausting excise (P<0.05, P<0.01). The levels of serum MDA and BUN, as well as the activities of AST, ALT and LDH in the model group were higher than those in the blank group (all P<0.01). The levels of serum MDA and BUN, as well as the activities of AST, ALT and LDH in the moxibustion group were lower than those in the model group (P<0.01). Conclusion: Moxibustion at Shenque (CV 8) can decrease the serum levels of MDA and BUN, as well as activities of AST, ALT and LDH in the long-term fatigue rats, thus to improve the symptoms of fatigue.
