Objective To discuss the clinical application and efficacy of digitization prototyping titanium meshes in the repairing of earthquake-induced skull defect. Methods The clinical data of 66patients with skull defect caused by earthquake were analyzed. These patients were divided into group A (treated with traditional handwork shaping titanium meshes, n=1S) and group B (treated with digitization prototyping titanium meshes, n=51). The efficacy and complications were compared.Results Compared to group A, group B had a shorter operation time, a shorter recovery time, a lower postoperative incidence rate of subcutaneous hematocele, hydrops and infection (P＜0.05). The digitization prototyping titanium meshes were significantly superior to handwork shaping titanium meshes (P＜0.05). And patients with skull defect repaired at early stage had a higher recovery rate of neurological function than those at advanced stage (P＜0.05). Conclusion Using digitization prototyping titanium meshes to repair the skull defect can enjoy anatomical reduction, shortened operation time, and fewer postoperative complications. In addition, an early repair in earthquake-induced skull defect can not onlydisburden patients' mind, but also prevent or even reverse secondary brain damage of skull defect,therefore, the patients' neurological function can be improved and their lives can be better.

OBJECTIVETo investigate the effects of burn serum on the viscoelasticity and the structure of rat intestinal epithelial cells.

METHODSThe rat intestinal epithelial cell strain (IEC-6) was cultured and stimulated by burn serum. The changes of IECs before and after the stimulation were dynamically observed by cytoskeleton immunohistochemistry, ELISA and the measurement of cytomembranous viscoelasticity.

RESULTSDuring the early stage of burn serum stimulation, the skeleton protein expression in IEC decreased obviously with weakened positive signals of microfilaments and microtubules and with decreased cellular elasticity.

CONCLUSIONThe cytoskeleton injury could cause the increase of cellular fragility and the decrease of the viscoelasticity, which ultimately lead to the change of cellular biodynamics. These changes might directly participate the development of postburn intestinal epithelial injury.

Objective:To preliminarily evaluate the effectiveness and safety of nalbuphine for patient-controlled intravenous analgesia (PCIA) after cesarean section.Methods:This study was a single arm clinical trial.Sixty parturients, aged 20-44 yr, weighing 50-80 kg, of American Society of Anesthesiologists physical status ⅠorⅡ, scheduled for cesarean section with epidural anesthesia, were enrolled in this study.PCIA was performed when visual analogue scale (VAS) score for postoperative pain ≥3 points following cesarean section.A bolus of nalbuphine 10 mg was intravenously injected as a loading dose.PCIA pump solution contained 110 mg nalbuphine diluted to 200 ml with normal saline.The pump was set up with a background infusion at a rate of 4 ml/h, 2 ml bolus dose and 15 min lockout interval.The VAS scores for pain at rest and during activity and uterine contraction pain, Ramsay sedation scores and adverse reactions were observed within 48 h after surgery.Results:The VAS scores for pain at rest and during activity and uterine contraction pain were all ≤3 points, the Ramsay scores were maintained at 2-4 points, hemodynamic parameters were maintained in the normal range, and no adverse reactions such as nausea and vomiting, drowsiness, hyperhidrosis, dizziness, pruritus, and respiratory depression occurred.Conclusion:PCIA with nalbuphine given according to the method mentioned above has good feasibility when used for analgesia following cesarean section.

OBJECTIVE: To explore the correlation between the interleukin-17 (IL-17) level of peripheral blood and aggression of bipolar mania. METHODS: Thirty-six patients of bipolar mania were selected as experimental group by DSM-IV-TR and received treatment with quetiapine and lithium. Thirty-six healthy volunteers with similar age and gender were selected as control group. The level of IL-17 at baseline in each group and the level of IL-17 in the experimental group after treatment for 2, 4 and 8 weeks were detected by ELISA. RESULTS: The level of IL-17 in experimental group at baseline, after treatment for 2 and 4 weeks were all significantly higher than that in control group. After 8 weeks treatment, there was no significant difference between the two groups (P > 0.05). After 2, 4 and 8 weeks treatment, the total score and aggression score of Young Mania Rating Score (YMRS) were significantly lower than the baseline level (P < 0.05). In experimental group, the level of IL-17 was positively correlated with the two scores of YMRS at baseline (P < 0.05). CONCLUSION Bipolar mania may be related to the up-regulation of IL-17. The level of IL-17 is related to the severity of manic symptoms at baseline, especially aggression symptom.

BACKGROUNDBenign prostate hyperplasia is one of the most common diseases affecting the health of the aging males. Watchful waiting is an acceptable management strategy for benign prostate hyperplasia in which the patient is monitored by the physician but receives no active intervention. The epidemiological data on this are lacking in China. Our study was designed to evaluate the changes of signs and symptoms of patients with benign prostate hyperplasia during management by watchful waiting in China.

METHODSOne hundred and forty-five patients with benign prostate hyperplasia aged > 50 years were enrolled in management by watchful waiting. All the patients were visited every 6 months and were given an International Prostate Symptom Score and Quality of Life questionnaire to complete. They also had uroflowmetry and were assessed using ultrasonography to get the volume of prostate, transition zone and amount of residual urine. The Student's t test, the Chi-square test, and variance analysis were used in the statistical analysis.

RESULTSAll patients were visited after 6 months, the mean volume of transitional zone was found to have increased by 1.6 ml (P < 0.01), International Prostate Symptom Score was increased by 0.8 (P < 0.01) and Quality of Life was increased by 0.2 (P < 0.01), and there was no statistical change in other data. Among these patients, 17.9% (26/145) visited again after 12 months when the data failed to show a statistically significant difference among the three groups (0, 6, and 12 months).

CONCLUSIONSAfter one year's follow-up, the progression of benign prostate hyperplasia was slow and the clinical data did not undergo much change.

OBJECTIVETo understand the predictive value of early monitoring BCR-ABL transcripts in patients with chronic myeloid leukemia (CML) after treatment with tyrosine kinase inhibitor (TKI), and to provides the information for early assessment of prognosis and treatment options.

METHODSBCR-ABL transcripts of 53 CML patients before and after TKI treatment were detected by using real-time quantitative RT-PCR. The relationship between BCR-ABL transcripts level after TKI treatment for 3 months and the later molecular response, progression and mutation was analyzed.

RESULTSThe median values of BCR-ABL transcripts in peripheral blood samples from 30 newly diagnosed patients were 43.99%, which was used as a baseline of BCR-ABL transcripts for molecular response evaluation. Of 53 patients, 31 (58.49%) had a BCR-ABL mRNA ≤ 4.40% (reduced more than 1 log) and 22 (41.51%) greater than 4.40% (reduced to less than 1 log) after 3 months of TKI treatment. The former 31 patients had a significantly higher 18-months cumulative incidence of major molecular response (MMR) (90.32% vs 18.18%, P=0.000) and 3-year cumulative incidence of complete molecular response (CMR) (48.39% vs 0, P=0.000) compared with the latter 22 patients. The lower BCR-ABL level was, the earlier MMR reached. The proportion of patients with a mutation in group of BCR-ABL mRNA>4.40% was significantly higher than that of BCR-ABL mRNA ≤ 4.40% (22.73% vs 0, P=0.021). The incidence of progression increased in group of BCR-ABL mRNA>4.40%, but the difference was not statistically significant (P=0.052).

CONCLUSIONIt is important for the prognosis evaluation of the patients to monitor the level of BCR-ABL transcripts at 3 months after TKI treatment, which might help to early optimization of treatment and to improve curative effect of CML patients.

OBJECTIVETo investigate the therapeutic effect of low-dose thyroxin in elderly patients with refractory heart failure (RHF) and euthyroid sick syndrome (ESS).

METHODSFifty-four elderly patients with RHF and ESS were randomized into conventional treatment group (n=32) and L-thyroxine group with additional oral L-thyroxine at the daily dose of 6.25-25 microg (n=22). The changes in the plasma levels of brain natriuretic peptides (BNP), left ventricular ejection fraction (LVEF), and cardiac function (NYHA level) of the two groups were compared after 1 month of treatment.

RESULTSFive patients receiving conventional treatment died due to severe arrhythmia during the treatment, and in the other 27 patients, the levels of plasma BNP, LVEF, and cardiac function showed no significant improvements after 1 month of treatment (P>0.01). In L-thyroxine group, no death or severe arrhythmia occurred, and the levels of plasma BNP, LVEF, and cardiac function were significantly improved after the treatment (P<0.01). No thyrotoxicosis occurred during the administration of L-thyroxine in the latter group.

CONCLUSIONLow-dose L-thyroxine in addition to the conventional treatments may enhance the therapeutic effect in elderly patients with RHF and ESS.
