OBJECTIVETo explore the effectiveness and safety of transcutaneous electrical acupoint stimulation (TEAS) combined with infusion of propofol in anodynia bronchoscopy.

METHODSNinety patients who received selective bronchoscopy were randomized into a group of compound TEAS with infusion of propofol (group A), a group of compound fentanyl with propofol (group B) and a group of simple propofol (group C). In group A, the plaster electrode stimulation was applied at bilateral Hegu (LI 4), Laogong (PC 8), Neiguan (PC 6) and Waiguan (TE 5). The anesthesia was induced after 20 min of stimulation till the end of examination. In group B and group C, the electric stimulation was not adopted. In group B, before anesthesia, fentanyl 1 microg/kg was injected intravenously. Afterwards, the intravenous infusion of propofol was used in the the three groups for anesthesia. The mean arterial pressure (MAP), heart rate (HR), saturation of pulse oximetry (SpO2) and respiratory rate (RR) were recorded at different time points. The induced dosage and total dosage of propofol, examination time, the awakening time and adverse reactions were observed in the patients of each group.

RESULTSThe difference in examination time was not significant among the three groups (P > 0.05). The postoperative awakening time in group A was earlier than that in group B and group C [(220.3 +/- 110.5) s vs (285.6 +/- 109.4) s, (290.1 +/- 105.1) s, both P < 0.05]. The total dosage of propofol in group C was larger than those in group A and group B [(288.5 +/- 26.7) mg vs (225.1 +/- 30.2) mg, (230.4 +/- 29.3) mg, both P < 0.05]. The induced dosage in group C was larger than those in group A and group B [(193.7 +/- 42.3) mg vs (152.3 +/- 36.1) mg, (155.4 +/- 40.5) mg, both P < 0.05]. Every life physical sign in group A during examination was more stable as compared with that in group B and group C. The incidence of hypotension and bradycardia in group A were lower than those in group C [3.3% (1/30) vs 26.7% (8/30), 0% (0/30) vs 20.0% (6/30), both P < 0.05]. The adverse incidence of oxygen supply in group A was lower than that in group B [6.7% (2/30) vs 33.3% (10/30), P < 0.05]. Intraoperative awareness and improper memory did not happen in postoperative investigation.

CONCLUSIONIn the transcutaneous electrical acupoint stimulation combined with infusion of propofol in anodynia bronchoscopy, the physical sign of patient is stable with less adverse reactions. This method reduces anesthetic dosage and shortens the postoperative awakening time, which can be effectively applied in bronchoscopy.

Objective:To evaluate the influence of platelet-rich plasma(PRP) on periodontal healing of replanted teeth in 6 Beagle dogs.Methods:The second incisors were pulled out and re-implanted after 60 min dry storage.In group A,PRP were applied before replantation,and 7days later the teeth received root canal treatment.In group B,PRP were applied before replantation either,but without root canal treatment.In group C,PRP were not applied and 7 days later,the teeth received root canal treatment.In group D,no PRP were applied and no root canal treatment.All the dogs were sacrificed after 12 weeks and the histological parameters were observed.Results:There were no significant differences between group A and C.Group B showed a lower incidence of ankylosis,and higher incidence of healed PDL compared with group D.Conclusion:Under the definite condition,PRP can help to decrease the incidence of ankylosis and increase the incidence of healed PDL in groups that the pulps were not removed.

27 autopsy cases died of anaphylactic shock induced by mainline during 1996-2005 were selected and analyzed. The results showed that most anaphylactic shock induced by mainline were rapid type and more easily happened in individual clinique and lawless clinique, and it could be arisen by either antibiotics or non-antibiotics. In some cases, there may be no pathologic findings by autopsy. So, all the materials must be taken into account for determination the anaphylactic shock, such as drugs, clinic symptom, autopsy findings, and so on.

Objective To investigate the effects of estrogen on mismatch repiar gene expression in colonic mucosa in vivo. Methods A total of 42 healthy individuals underwent colonoscopy were enrolled in the study. Half an hour before colonoscopy examination, blood sample was taken for determining the serum estradiol (E2) level. N ormal colonic mucosal tissues determined by naked eye under colonoscopy examination were taken in the right hemi colon to detect HMLH1 and hMSH2 gene expression by semi-quantitative RT-PCR and immunohistochemistry staining. Then the correlation of serum E2 levels with hMLH1 and hMSH2 expression in colonic mucosa was analyzed. Results A bimodal curve was presented for the correlation between serum E2 level in healthy individuals and hMLH1 expression in colonic mucosa. A strong positive correlation of E2 level with hMLH1 expression in normal colonic mucosa was observed when serum E2 level was more than 45 pg/ml (For mRNA, P=0. 003, r=0. 701; for immunohistochemistry positivity index, P=0. 000, r=0. 874).However there was no correlation between E2 level and hMSH2 expression. Conclusion High serum E2 level might increase the hMLH1 gene expression in colonic mucosa in vivo.

OBJECTIVETo investigate the short-term clinical outcome of unicompartmental knee arthroplasty for the treatment of spontaneous osteonecrosis of the knee.

METHODSFrom September 2013 to April 2014,5 patients with spontaneous osteonecrosis of the knee underwent unicompartmental knee arthroplasty, included 3 males and 2 females, aged from 65 to 80 years old with an average of 74 years. The courses of disease was from 1 to 6 years with the mean of 3 years. According to the radiographic staging criteria of Koshino, 1 case was stage II, 2 cases were stage III, 2 cases were stage IV. Clinical effects were assessed by VAS score, HSS score, and knee range of motion, tibiofemoral angle before and after operation.

RESULTSAll the patients were followed up from 6 to 7 months with an average of 6.4 months. All incisions obtained primary healing, and there were no complications such as infection, thrombosis, fracture of lower limbs. All 5 patients' pain relieved and their knee function improved significantly after operation, but knee range of motion had no obviously improved. Postoperative HSS scores, VAS scores, tibiofemoral angle were significantly improved than that of preoperative.

CONCLUSIONThe short-term effect of unicompartmental knee arthroplasty in treating spontaneous osteonecrosis of the knee is satisfactory.

Cerebral venous and sinus Thrombosis (CVST) is a rare ischemic cerebrovascular disease,the lesions of 60% patients are involved in multiple venous sinus,of which the superior sagittal sinus thrombosis is most common.The pathogenesis and pathophysiology of CVST has not yet been fully elucidated,and the establishment of stable and ideal animal models can provide a basis for the study of its development,prognosis and efficacy assessment.This article summarizes the characteristics and advantages of several available CVST models,but each method has its own limitations.Therefore,the establishment of a more ideal animal model will help to fully understand the pathogenesis and pathological process of CVST.

Objective To evaluate the characteristics and efficacy of microscope-assisted bilateral decompression via unilateral approach for the treatment of lumbar stenosis. Methods From June 2007 to June 2010, Sixty case lumbar stenosis with bilateral decompression were treated via unilateral approach under microscopy. Patients were followed up from 6 to 24 months, average (12 ± 4.7) months. Results The pain level of each patient was assessed both before and after the opeartion, using a visual analogue scale (VAS). Intermittent claudication was completely relieved in 57 out of 60 cases, moderately relieved in 3 cases. VAS score decreased from pre-operational 9.08 ± 0.76 to post-operational 2.33 ± 1.43, and there was significantly difference between them. There was no recurrent case during the whole follow-up. Conclusion Bilateral decompression via unilateral approach under microscope is proved to be an effective and safe procedure for the treatment of lumbar stenosis, and have the advantages of minimal invasion, less pain, quick recovery, better effect, little influence on the spinal stability.
