Objective To introduce a method to aid dental treatment for autistic children; midazolam oral sedation. Methods 10 autistic children who can not be managed under normal dental procedures were administrated oral midazolam (0.5mg/kg) before treatment. Once they were adequately sedated, dental treatment was carried out in outpatient. During the whole course, their finger oxygen saturation and heart rate were inspected. Painless methods were also applied. The duration of each treatment was controlled within 30min. When the procedure ended, the autistic children were inspected until recovery from sedation and then discharged with their parents. Results 10 children aged 4～10y totally underwent 17 visits to complete all dental treatment. The average ages were (6.00?1.89)y, body weight was (28.10?9.36) kg and Houpt scales were (4.71?0.77). They were all successfully sedated and managed and no severe complications were found. Conclusion The oral midazolam sedation showed satisfactory effects on this group of autistic children while studies of large samples are needed to draw a definite conclusion.

ObjectiveTo evaluate clinical efficacy ofYupingfeng Granules combined with western medicine for children with recurrent respiratory tract infection (RRTI).Methods CNKI, VIP, WANFANG DATA, SinoMed, PubMed, Embase, and Cochrane Library were searched for the randomized controlled trials (RCTs) that investigated the clinical and immune effects ofYupingfeng Granules in children with RRTI from inception to October 2015. Two researchers independently screened studies according to the inclusion and exclusion criteria, extracted data and evaluated the methodological quality of included studies. Then Meta analysis was performed through the software RevMan 5.3.Results A total of 8 articles involving 550 patients were included. The results of Meta analysis showed effective rate ofYupingfeng Granules combined with western medicine for children with RRTI [OR=4.16, 95%CI (2.49, 6.95),P<0.000 01], IgA level [MD=0.52, 95%CI (0.26, 0.78),P<0.000 1], IgG level [MD=2.75, 95%CI (1.25, 4.25),P=0.000 3], CD4+ level [MD=6.15, 95%CI (4.76, 7.54),P<0.000 01], CD4+/CD8+ level [MD=0.36, 95%CI (0.25, 0.47),P<0.000 01]. All of the above were superior to single western medicine treatment. There was no statistical significance in levels of IgM and CD8+(P>0.05). ConclusionYupingfeng Granules combined with western medicine can improve effective rate, antibody level and T-cell level in the treatment of children with RRTI. The overall clinical efficacy is better than single western medicine treatment. However, RCTs with large samples, multiple centers and high quality are needed for further verification.

Conclusion Double gene expression vector pIRES-PSMAe/p-TK-Cx43 containing HSV-TK gene and Cx43 gene is constructed successfully.

Objective: To summarize the research status of the changes in local microenvironment of acupoints caused by acupuncture, provide theoretical guidance for the initiation mechanisms of local acupuncture effect at acupoints. Methods: Using acupuncture, acupoint as key words to search China National Knowledge Infrastructure (CNKI), Wanfang Academic Journal Full-text Database (Wanfang), Chongqing VIP Database (CQVIP), PubMed and other databases, the representative articles were selected for review. Results: Acupuncture could excite afferent nerves, activate cells, and promote the release of chemical substances like neuropeptide, hormone, cytokines, etc. in the local site of acupoints. Besides, it may cause mechanical deformation of connective tissues, and change chemical ions as well as ion channels. Conclusion: The microenvironment changes around acupoints are crucial to acupuncture effect; the concept of 'acupoints network' can be used to objectively describe the local changes around the acupoints after acupuncture.

Ann Arbor staging showed that 25 cases were stageⅢ-Ⅳ(92.6%), 8 cases were heptosplenomegaly (29.6%), 7 cases showed extranodal involvement (25.9%). ECOG scoring showed that 4 cases with scores of 2-4 (14.8%), 8 cases were 0-3 (29.6%), 14 cases were 4-5 (51.9%) and 5 cases were 6-11 (18.5%). The Ki-67 index≤30%was found in 9 cases (33.3%), and>30%was found in 18 cases (67.7%). Patients with B symptom was found in 10 (37.0%). The elevated lactate dehydrogenase (LDH) was found in 17 cases (63.0%). The increased Beta 2- microglobulin was found in 8 cases (29.6%). Seven patients were found with bone marrow involvement. The total effective rate (ORR) was 81.8%in group with R-CHOP method, and the ORR was 68.8%in group with CHOP method. Multivariate analysis showed that age, LDH and Ki-67 were independent factors influencing the prognosis of MCL (P<0.05). Conclusion Most patients with MCL are found in advanced stage. Patients with age>60 years, elevated LDH and Ki-67 index>30%are with poor prognosis.

Based on the structure and function of acupoint and in association of the definition and principle of sensor, the acupoint is the sensitive element, being sensitive to the physical stimulation with acupuncture and moxibustion and sensitively responded to the disorders; the acupoint is the sensing element, transforming the changes of the acupoint information via the complicated internet conduction, integration and regulation, so as to generate the effects on organic body; the acupoint is the conversion element, transforming every irritation into the bioelectric signal or optical signal so that the organic body could recognize it. Therefore, the acupoint is regarded as the sensor of information in the organic body.

OBJECTIVETo evaluate the sedative effect of continuous intravenous infusion of midazolam in treating severe dental phobia.

METHODS31 patients with severe dental phobia were enrolled and all of them had good communication with dentists. Two teeth in each patient were assigned to control group and experiment group seperately. The control group received root canal therapy. The experiment group were sedated by intravenous midazolam and received root canal therapy. The treat dependence and behavior therapy efficacy were evaluated. The vital signs and side effects during treatment were noted.

RESULTSContinuous intravenous infusion of midazolam showed a significant good sedative effect on patients with severe dental phobia. There were statistical difference in the Houpt score and the Frankl score between experiment group and control group (z = -4.846, P = 0.000; z = -4.907, P = 0.000). The total dose of midazolam was (9.58 +/- 3.76) mg, and mean infusion rate was (0.28 +/- 0.06) mg x kg(-1) x h(-1). The blood pressure, heart rate and respiration of experiment group were depressed. But these changes didn't interfere with the completion of the whole treatment. No severe side effects were detected.

CONCLUSIONThe single use of midazolam as an intravenous sedation agent has satisfactory effect on patients with severe dental phobia.
