Luteinized unruptured follicle syndrome (LUFS), a specific type of ovulation disorder, is for a cause of female infertility. Acupuncture therapy has a good effect for LUFS. In order to understand the clinical effects and research situation of acupuncture therapy for LUFS, the author analyzed and reviewed the relevant literature. It was indicated by the findings that acupuncture therapy and integrative therapy of acupuncture and Chinese herbs have good therapeutic effect for this disease. Acupuncture therapy has the effect to promote ovulation. By the therapeutic principle to tonify the kidney and circulate blood, acupuncture therapy mostly was adopted in the period of ovulation. The acupoints are mostly selected from the lower abdomen and lower limbs, possibly based upon syndrome differentiation at the same time. The needling techniques are of certain characteristics. But, the issues of low quality, un-standardized inclusive, exclusive criteria and effective criteria still exist in the current clinical study.

OBJECTIVETo establish a general method of focal cerebral ischemia model in different varieties of mice.

METHODEach group of healthy adult KM and C57BL/6 mice were randomly divided into control group (n = 10) and MCAO group (n = 10). The mice in MCAO group were applied in the preparation of the MCAO model by intraluminal occlusion using monofilament. Twenty-four hours after operation,the neurologic function was evaluated,middle cerebral artery blood flow was monitored and the infarction volume was calculated by TTC staining, to evaluate the reliability of the model.

RESULTIn the MCAO group, the base value of the cerebral blood flow down of KM and C57BL/6 mice respectively was (81.65 ± 4.59)%, (83.68 ± 6.25)%. The neurological deficit score respectively was (2.30 ± 0.82), (2.50 ± 0.80). TTC staining can clearly show the infarction area, and relatively stable, 24 hours of the survival rate of KM and C57BL/6 mice were 100% and 80% respectively.

CONCLUSIONThe key link is the optimization and improvement of monofilament, temperature, anesthesia and so on. The modified intraluminal occlusion of MCAO using monofilament is a kind of reliable and simple method to establish experimental cerebral ischemia model in mice.

Objective To investigate the role of IL-6/STAT3 signaling in Th17/Tr imbalance of Kawasaki disease(KD). Methods Forty-eight children with KD and eighteen age-matched healthy children were consented to participate in this study. Protein concentration of IL-6 in plasma was measured by ELISA. Transcriptional levels of IL-17A, IL-17F, RORγt, Foxp3, SOCS1 and SOCS3 were assessed by real-time PCR. The proportion of CD4+CD25+Foxp3+ regulatory T(Tr) cells and mean fluorescence intensity(MFI) for phosphorylated-STAT3(pSTAT3) protein in CD4+ T cells was analyzed by flow cytometry. A quantitative methylation specific PCR based on SYBR Green was used to evaluate methylation status of CpG islands in SOCS1 exon2, three potential bind sites for STAT3 in 5'-untraslated region(5'-UTR) of SOCS3 in CD4+ T cells. Results (1)Compared with healthy volunteers, plasma IL-6 concentration and MFI for pSTAT3 in CD4+ T cells were elevated significantly during acute phase of KD[IL-6:(54.02±20.58) pg/ml vs (8.72±2.06) pg/ml, P<0.05;pSTAT3 MFI:(55.41±15.08) vs (9.35±3.76), P<0.05], and the two items in KD patients with coronary artery lesion (KD-CAL+) were found to be higher than those in KD patients without coronary artery lesion (KD-CAL-)[IL-6:(84.76±29.35) pg/ml vs (38.65±13.76) pg/ml, P<0.05;pSTAT3 MFI:(72.36±16.81) vs (46.93±13.57), P<0.05]. (2)Transcription levels of IL-17A, IL-17F and RORγt in patients with KD were significantly elevated (P<0.05) while the proportion of CD4+CD25+Foxp3+ Treg and expression levels of Foxp3 were detected to be lower than those in normal controls (P<0.05). The mRNA levels of IL-17A, IL-17F and RORγt in KD-CAL+ group were higher than those in KD-CAL- group(P<0.05), as well as expression level of Foxp3 were found to be lower in KD-CAL+ group(P<0.05). (3)The mRNA levels of SOCS1 and SOCS3 in CD4+ T cells increased significantly during acute phase of KD(P<0.05), while the two items in KD-CAL+ group were lower than those in KD-CAL- group(P<0.05). Furthermore, CpG islands in SOCS1 exon2 and the third potential bind site for STAT3 in SOCS3 5'-UTR were hypomethylated in acute KD, while those in healthy controls were fully demethylated(P<0.05). Demethylation levels of SOCS1 exon2 and the third potential bind site for STAT3 in SOCS3 5'-UTR in KD-CAL+ group were lower than those in KD-CAL- group(P<0.05). CpG islands in the other two bind sites for STAT3 in SOCS3 5'-UTR were fully demethylated among all the groups(P>0.05). ConclusionAberrant activation of IL-6/STAT3 signaling caused by hypomethylation of SOCS1 and SOCS3 might be one contributing factor to unbalance of Th17/Tr in KD.

The molecular delivery vectors used in gene therapy need provide the features of safety,stability, efficiency and capacity. The current studies on the structure and action mechanism of pRNA, a packaging RNA of phage?29, showed that pRNA with multiple binding sites can through cell membrane easily and escort exogenous molecules to target cell, without inducing immune reaction. As an ideal nano-scale gene therapy vehicle, pRNA presents a promising application in delivering multiple therapeutic components to detect and treat human diseases.

This paper investigated contamination situation of Listeria monocytogenes(Lm). To compare dif- ferent selectivity enrichment broth for detectable effect of Lm and compare detectable effect in different samples by using different methods, furthermore, choose the best enrichment broth for specific food. One hundred and thirty five random samples from raw meat, aquatic product, fruit and vegetable, quick-frozen food in Baoding. Applied LB enrichment broth, EB enrichment broth, new modification FDA enrichment broth and Fraser enrichment broth before separated by PALCAM selective agar, then identified by interna- tional standard method after PCR. Results: Four methods showed that there were 23 Lm positive, detected 5 Lm by LB method, 6 Lm by Fraser method, 5 Lm by EB method and 7 Lm by new modification FDA method. The total detectable rate of four methods had no large specificity, but to specific kind of food was different.
