Objectives: To evaluate the analgesic effect of electronic dental anesthesia(EDA).　Methods: Sixty patients with dental caries in need of cavity preparation and 15 patients with pulpitis in need of pulp treatment were anesthetized with EDA, another 60 patients with dental caries in need of cavity preparation and 15 patients with pulpitis in need of pulp treatment were anesthetized with traditional local anesthesia(LA).　 Results: For patients with dental caries in need of cavity preparation, the effective rates in EDA group and LA group were 93.33% and 98.33% respectively(P>0.05).For patients with pulpitis in need of pulp treatment ,the effective rates in EDA group and LA group were 26.7% and 93.33% respectively(P<0.01).　Conclusions: EDA can be an effective analgesic method for cavity preparation, but not for pulp treatment.

Objective To evaluate the clinical effectiveness of heat-sensitive moxibustion for knee osteoarthritis ( KOA) by systematic evaluation and Meta analysis methods. Methods Electronic information retrieval combined manual retrieval methods were used for collecting clinical randomized control trial of heat-sensitive moxibustion for KOA. The systematic evaluation was conducted by two individual researcher following the principles of Cochrane Review Handbook 5.1, and RevMan5.0 software was applied for the statistical analysis. Results Fifteen randomized controlled trials (RCT) were enrolled into the analysis, which involved 1228 cases. The results of systematic evaluation showed that the quality of most of the enrolled RCT were not so high. The results of Meta analysis were as follows: ( 1) Between heat-sensitive moxibustion and traditional moxibustion, the weighted mean difference (WMD) and 95%confidence index (CI) were-1.76, [-2.33, -1.18] for visual analog scale ( VAS) scores ( P<0.001) , were -2.36, [-3.42, -1.30] for the scores of guiding principle of clinical research on new drugs ( GPCRND) for KOA ( GPCRND-KOA) ( P<0.001) , and were 13.61, [7.60, -19.61]for Lysholm knee joint function scores (P<0.001), respectively; (2) Between heat-sensitive moxibustion and acupuncture, WMD and 95%CI were 6.19, [ 0.01, 11.37] for Lysholm scores ( P<0.05);(3) Between heat-sensitive moxibustion and warm-needling acupuncture, WMD and 95%CI were -10.14, [-17.47, -2.81] for the Western Ontario and McMaster Universities ( WOMAC) osteoarthritis index scores ( P<0.05). Conclusion It is indicated that heat-sensitive moxibustion shows certain therapeutic effect for knee osteoarthritis, better than traditional moxibustion.

[ Objective] To observe the effect of removing phlegm,softening and removing blood stasis on pulmonary morphology and hydoxyprolin of pulmonary fibrosis rats. [Methods]The experimental pulmonary fibrosis models were produced by injecting BLMA5.All animals were randomly divided into 5 groups which were control group, model group, Chinese herb high-dose group, Chinese herb low-dose group and prednisone group respectively, the drugs were given daily starting from the second day and the rats were killed on the 7th and 28th day. The shape of rats’ lung tissues was observed, the levels of hydroxyproline in lung tissues were measured. [Results] In model group, alveolitis increases(much inflammatory cell infiltration), pulmonary interstitial fibroblast increases. There is less pulmonary tissue inflammatory cell infiltration in drug-given groups than that in model group and so is fibroblast. Compared with the model group, the content of HYP of pulmonary tissues of the drug-given groups is remarkably decreased. [Conclusion] The Chinese herb of removing phlegm, softening and removing blood stasis can effectively inhibit the formation of pulmonary fibrosis caused by BLMA5.

[Summary] The general status of glycemic control and insulin initiation are not optimistic in Chinese patients with type 2 diabetes.Chinese patients experience pancreatic β-cell dysfunction and reduction of early phase insulin spike earlier and more severely compared to Caucasians.These can cause more significant postprandial hyperglycaemia which is further deteriorated by traditional carbohydrate-rich Chinese diet.Therefore,premixed insulin may be a more appropriate option of insulin initiation therapy for Chinese patients with type 2 diabetes mellitus.

OBJECTIVE To explore the risk factors in elderly patients with ventilator-associated pneumonia(VAP) and to provide the corresponding clinical prevention strategies.METHODS The ages,underlying diseases,mechanical ventilation method,use of antibiotics,and pathogenic bacteria of the VAP patients were investigated and analyzed.RESULTS Totally 105 elderly patients with VAP had serious underlying diseases,and were treated with broad-spectrum antibiotics,tracheal intubation or trachea incision.Most pathogenic bacteria were multiresistant.CONCLUSIONS Prevention of VAP is the priority of treatment for elderly patients.In order to control the occurrence and spread of VAP,clinicians should shorten the time of ventilator treatment,pay more attention to sterilization and isolation,and strengthen the attendance of the patients.

A case of primary tracheobronchial amyloidosis in a 29-year-old woman was reported. 3-D reconstruction imaging by CT well delineated bronchial irregularity and narrowing. SPECT with ^99mTc-MDP and Ga-citrate demonstrated radionuclide activity consistent with the sites of calcified deposits.

After birth,human intestinal tract mucosa is exposed to a large community of commensal and pathogenic bacteria. As a first line of defense,the intestinal epithelial barrier (IEB) kills the pathogen by signaling to the innate immune system, through pattern recognition receptors, while it produces protective respond towards the commensal bacteria. Intestinal epithelial cells play an important role in forming immune tolerance to the commensal bacteria and make intestinal homeostasis. Commensal bacteria can resist the pathogenic bacteria invasion. The signals of commensal are required for development of intestinal epithelial barrier and intestinal innate and adaptive immunity. It is essential for the host to have a balance between the commensal bacteria and intestinal tract,once the balance is broken, the intestinal inflammation disease will be caused. Thus ,this review will discuss the relationship between intestinal commensal bacteria and intestinal epithelial barrier in several aspects, such as the role of the commensal bacteria, the mechanism of producing commensal tolerance by IEB and the disease caused by imbalance between the commensal and IEB.
