Objective To investigate the outcomes of patients undergoing off-pump coronary artery bypass grafting (OPCABG) under morphine-fentanyl combined anesthesia. MethodsSeventy-two patients aged 41-64 yr undergoing OPCABG were randomly divided into 2 groups (n = 36 each): Ⅰ group morphine + fentanyl (group MF) and Ⅱ group fentanyl (group F). Anesthesia was induced with midazolam, etomidate, and vecuronium.Fentanyl 10-20 μg/kg was given iv when needed. The patients were mechanically ventilated after tracheal intubation. Anesthesia was maintsined with inhalation of 0.5%-2.0% isoflurane and intermittent iv boluses of vecuronium in both groups. Morphine 0.15 mg·kg-1·h-1 + fentanyl 8 μg·kg-1·h-1 were infused during operation in group MF, while in group F fentanyl 10 μg·kg-1·h-1 was infused. Morphine 0.75 mg/h was infused in group MF or fentanyl 10 μg/h in group F for postoperative analgesia after extubation. Recovery from anesthesia was assessed using a nine point (QoR) questionnaire. Pain was measured with VAS score and sedation with Ramsay sedation score ( 1 = fully awake, 6 = asleep, no response to verbal stimulus). The postoperative complications were recorded. ResultsQoR scores were significantly higher in group MF and in group F. The incidence of postoperative febrile reaction was significantly reduced in group MF. There was no significant difference in Ramsay sedation score and other postoperative complications between the 2 groups. ConclusionMorphine-fentanyl combined anesthesia is more beneficial for the prognosis in patients undergoing OPCABG compared with fentanyl combined anesthesia.

Objective:To investigate the effects of 5-aza-2′deoxycytidine(5-aza-dC),a DNA methyltransferase (DNMT)inhibitor, on the methylation status of the RECK gene and the invasion of salivary adenoid cystic carcinoma cell lines.Methods:Methylation-specific PCR,Western blot analysis and quantitative real-time PCR were used to investigate the methylation status of RECK gene and the expression of RECK mRNA and protein in SACC cell lines.The invasive ability of SACC cells was examined by transwell assay. Results:Promoter methylation was only found in ACC-Mcell line and not in ACC-2 cell line.Treatment of ACC-Mcells with 5-aza-dC partially reversed the hypermethylation status of the RECK gene and significantly enhanced the expression level of mRNA and pro-tein of RECK,suppressed ACC-Mcell invasive ability.Conclusion:5-aza-dC can inhibit ACC-Mcell invasion by reversal of hyperm-ethylation status of RECK gene.

OBJECTIVE:
To improve diagnosis and treatment level of foreign body ingestion of button cell in children.
METHOD:
Among the 14 cases with foreign bodies ingestion of button cell, 6 cases in esophageal, 7 cases in stomach and lower gastrointestinal tract, 1 case with multiple foreign bodies both in esophagus and stomach. Seven cases in stomach and lower gastrointestinal tract were closely observed without special treatment, 6 cases in esophageal, underwent esophagoscopy and removal of foreign body under general anesthesia, 1 case with multiple foreign bodies in esophagus and stomach underwent esophagoscopy and electronic gastroscopy and then removal of foreign body. All patients had symptomatic treatments after removal of foreign body. The average age is 2 years and 1 month.
RESULT:
After the removal of button cell, Foreign bodies in stomach and lower gastrointestinal tract in 7 cases were all discharged spontaneously. For the 6 cases in esophagus, 4 cases were cured, 1 case had esophageal stricture, 1 cased died. 1 case with multiple foreign bodies in both esophagus and stomach was cured.
CONCLUSION
Esophageal foreign body has strong corrosiveness and would cause serious damages even to threaten children's life. It also may lead to esophageal stricture. The key point to cure this disease is to diagnose timely and to operate as soon as possible. Because neutralize of digestive juices and low probability of incarceration, with close observation, the foreign bodies of stomach and lower gastrointestinal tract can discharge spontaneously.

BACKGROUND: The etiology of lumbar muscle strain is unclear, and it is a kind of specific disease. Lumbar muscles strain not only affects quality of life and work, but also causes heavy medical burden and indirect social costs. OBJECTIVE: To explore the effect of electropuncture and core strength training on lumbar muscle strain in college students. METHODS: The study was in accordance with the ethics requirements of Guangxi Normal University. Eighty college students with lumbar muscle strain were selected, and they signed the informed consents. The participants were randomized into control group (no intervention), electropuncture group, core strength training group, electropuncture with core strength training group. The intervention time was 7 weeks. The Visual Analogue Scale scores and pain system scores at baseline and after treatment were recorded. The recurrence was measured after 4 months of follow-up. RESULTSANDCONCLUSION: (1) The Visual Analogue Scale scores and pain system scores in the electropuncture, core strength training, and electropuncture with core strength training groups were significantly decreased compared with the baseline scores (P < 0.05). (2) The Visual Analogue Scale scores and pain system scores in the electropuncture, core strength training, and electropuncture with core strength training groups were significantly lower than those in the control group after intervention, and the scores in the electropuncture with core strength training group were significantly lower than those in the electropuncture and core strength training groups (P< 0.05). (3) The healing rate in the core strength training and electropuncture with core strength training groups was significantly higher than that in the electropuncture group, and the treatment efficacy in the core strength training and electropuncture with core strength training groups was significantly superior to the electropuncture group (P<0.05). (4) The recurrence in the core strength training and electropuncture with core strength training groups was significantly lower than that in the electropuncture group (P<0.05). (5) These results indicate that electropuncture and core strength training both have certain treatment efficacy for lumbar muscle strain in college students and core strength training is better than electropuncture, with lower recurrence. The synergistic effect of the combination of core strength training and electropuncture for lumbar muscle strain in college students is remarkable.

OBJECTIVE:
To study the effectiveness of tympanoplasty for treatment of chronic otitis media and cholesteatoma in children.
METHOD:
Twenty-three cases with chronic otitis media and cholesteatoma treated by tympanoplasty were retrospectively studied, among which 15 cases had complete clinical data. The condition of surgical cavities, the duration of getting dry ears, the hearing improvements, the growth of new ear drums and whether the recurrence of cholesteatomas occurred or not were observed.
RESULTS:
In all patients, the chief complains were ear discharging and hearing loss. The tympanum membranes(pars flaccid or pars tensa) became retracted or perforated and CT scan showed mastoid processes were poor developed in some cases with lesions mainly located at attic, middle tympanum cavity and/or petrous parts. The duration of getting dry ear was (6.0 +/- 1.5) weeks after surgery. The effective rate was 80%. The hearing of 12 cases has been improved, that of 2 cases has no changed, that of 1 case has been descended, and 1 case exhibited recurrent cholesteatoma after surgery.
CONCLUSION
This study demonstrated that children's chronic otitis media and cholesteatoma have their own clinic features of wide erosiveness and strong aggressiveness, and tympanoplasty has been proved to treat this disease effectively, also been proved to improve these patients' hearing cognitions and eventually improve their life qualities.
