Objective To investigate the value of Xueshuangtong combined with radiofrequency thermocoagulation in the treatment of lumbar degenerative lumbar pain.MethodsFrom January 1, 2014 to December 30, 2015, 60 patients with lumbar degenerative low back pain admitted in Jiashan Traditional Chinese Medicine Hospital.All of them were randomly divided into observation group and control group, and each with 30 cases.All patients received radiofrequency thermocoagulation, while the observation group received Xueshuantong for further treatment.All of the patients were assessed by the international Pain Association recommended the use of visual analogue scale (VAS) and McGill pain questionnaire (SF-MPQ) and CRP when treatment before starting and after 1, 3, 7, 14, 30 and 90d of the treatment.ResultsThere were no significant differences between the two groups in VAS, SF-MPQ and CRP before treatment (P<0.05).However, when compared with the control group, patients in the observation group got significantly lower levels of VAS at 1, 3, 7 and 14d after the operation;significantly lower levels of SF-MPQ at 1, 3, 7, 14 and 30d after the operation;and significantly lower levels of CRP at 14, 30 and 90d after the operation (P<0.05).And we found no serious complications occurred in the two groups.ConclusionThe Xueshuantong combined with radiofrequency thermocoagulation treatment of lumbar facet joint is a safe, effective and inexpensive for the low back pain which caused by lumbar degeneration.

Objective To study the clinical application of laparoscope combined with gastroscope surgery in patients with gastric stromal tumor. Methods The clinical data of 50 patients with gastric stromal tumor were retrospectively analyzed. Among them 20 cases were treated with traditional laparotomy (laparotomy group), and 30 cases were treated with laparoscope combined with gastroscope surgery (combination group). The intraoperative bleeding, operation time, postoperative recovery time, postoperative hospitalization time and complications were compared between 2 groups. Results One case in combination group received open surgery (3.33%, 1/30), mainly because of obesity, and tumor rupture occurred in 1 case during operation. All specimens of the 2 groups had no tumor residue. There were no statistical differences in tumor diameter and operation time between 2 groups (P>0.05); the intraoperative bleeding, postoperative recovery time and postoperative hospitalization time in combination group were significantly lower than those in laparotomy group:(26.33 ± 14.21) ml vs. (42.57 ± 15.67) ml, (37.96 ± 8.80) h vs. (60.14 ± 13.41) h and (6.42 ± 2.80) d vs. (12.04 ± 4.69) d, and there were statistical differences (P<0.05). The 2 groups had no death, stomach bleeding, anastomotic stenosis and anastomotic leakage. The laparotomy group had postoperative incision fat liquefaction in 3 cases and incision infection in 2 cases, and the combination group had pulmonary infection in 1 case. All were cured after symptomatic treatment. Conclusions Laparoscope combined with gastroscope surgery in the treatment of gastric stromal tumors has a short operation time, less blood loss, faster postoperative gastrointestinal function recovery, shorter hospitalization time, and no major complications. It is a more ideal and minimally invasive surgery.

Objective To investigate the influence of discontinuance of methimazole (MMI) and propylthiouracil (PTU) on 24 h radioactive iodine uptake(RAIU) in normal rats.Methods A total of 66 female SD rats were randomly divided into 3 groups by simple random sampling method.MMI group (30 rats) received MMI with a dose of 0.6 mg·ml-1·d-1 orally for 2 weeks, PTU group (30 rats) received PTU with a dose of 6 mg·ml-1·d-1 orally for 2 weeks.At 1, 3, 5, 7 and 9 d after MMI or PTU was discontinued, 6 rats were sacrificed to measure 24 h RAIU respectively.The control group (6 rats) received normal saline with a dose of 1 ml/d orally for 2 weeks, and then they were sacrificed to measure 24 h RAIU too.Data were analyzed with two-sample t test or t′ test.Results Thyroid 24 h RAIU in normal rats was (14.6±4.3)%.The 24 h RAIU on 1, 3, 5, 7 and 9 d was (4.6±0.7)%, (24.2±7.2)%, (13.1±2.9)%, (14.1±2.6)%, (16.1±3.7)% respectively after MMI withdrawal.The 24 h RAIU was significantly lower than that in control group at day 1 (t′=5.55, P<0.01), higher at day 3 (t=-2.83, P<0.05), and returned to the normal level at day 5, 7, 9 (t=0.68, 0.24,-0.67, all P>0.05).The 24 h RAIU on 1, 3, 5, 7 and 9 d was (1.9±0.8)%, (3.3±1.2)%, (7.7±2.4)%, (29.0±4.0)%, (17.1±4.8)% respectively after PTU withdrawal.It was lower than that in control group (t=7.01, 6.10, 3.40, all P<0.05) at day 1, 3, 5, and higher at day 7 (t=-5.97, P<0.01).The 24 h RAIU of 9 d showed no difference when compared with that in control group (t=-0.95, P>0.05).Conclusions MMI and PTU can inhibit the iodine uptake of thyroid, the 24 h RAIU returns to normal level at day 5 after withdrawal of MMI and at day 9 after withdrawal of PTU in euthyroid rats.

Objective: To search for the best condition of microwave assisted extraction(MAE) for the flavonoids in Radix glycyrrliza and to compare with traditional boiling water extraction(WE). Methods: MAE and BWE were adopted, and its proper experimental conditions were examined and optimized by means of uniform design. The flavonoids in Radix glucyrrliza were determined by spectrophotometry. Results: Appropriate MAE conditions included extraction time of 1min, ethanol concentration of 38%, liquid/solid ratios of 8∶1(ml/g) and the power of microwave oven of 288W, the recovery of flavonoids from Radix glycyrrliza with MAE(24.6mg/g) was higher than BWE (11.4mg/g). Conclusion: Compared with traditional boiling water extraction(BWE), the experiment results demonstrated higher extracting rate and shorter extracting time. It indicated that MAE was more suitable to extraction of the flavonoids.

Objective:To evaluate the diagnostic performance of probe-based confocal laser endomicroscopy (pCLE) for indeterminate biliary strictures.Methods:Twelve patients with indeterminate biliary strictures who underwent pCLE and brush cytology from April 1, 2013 to December 30, 2016 were enrolled. Clinical data, the results of endoscopic retrograde cholangiopancreatography, pCLE examination and brush cytology were collected. Compared with post-operative pathology and follow-up over 12 months, sensitivity, specificity, positive predictive value(PPV), negative predictive value(NPV), and accuracy of pCLE and brush cytology of the diagnosis of malignant biliary strictures were analyzed.Results:The final diagnosis were 9 malignant and 3 benign. The sensitivity, specificity, PPV, NPV and accuracy of brush cytology were 3/9, 3/3, 3/3, 3/9 and 50.0%(6/12), respectively. The corresponding indicators of pCLE were 9/9, 2/3, 9/10, 2/2, and 91.7%(11/12), respectively.Conclusion:pCLE can be used for differential diagnosis of indeterminate biliary stricture.

OBJECTIVETo investigate the application of three-dimensional CT(3D-CT) in the treatment of oblique facial clefts with mandibular outer cortex, including the surgical design and results assessment.

METHODSFrom Jan. 2003 to Dec. 2013, 22 cases with oblique facial cleft, who underwent mandibular outer cortex onlay bone graft were retrospectively studied. 3D images from CT data were reconstructed before operation for design. Then the mandibular outer cortex onlay bone transplant was performed to reconstruct the bone defect and cleft. 3D CT was performed 5-10 days postoperatively and 6- 12 months postoperatively to assess the facial symmetry.

RESULTSAccording to the results of CT measurement, the average volume of the orbital bone defects on the affected side decreased by(64. 6 ± 14. 4)% 5 to 10 days after operation. The average volume of the maxillary and zygomatic bone defects on the affected side decreased by(71.4 ± 15.7)% after surgery. After 6 to 12 months,the average recovery of the mandibular donor site was (57. 9 ± 13. 9)% of the removed mandibular outer cortex. The average absorption of grafted bones was(24.7 ± 25.6 )%. The average height difference between the centre of pupils on both sides before surgery was(3.76 ± 1.27) mm,which decreased to( 1. 15 ± 1.00) mm 5 to 10 days after surgery(P =0. 000) , and( 1.35 ± 1. 13) mm 6 to 12 months after surgery(P = 0. 003). The relapse may be caused by the absorption of the grafted bones.

CONCLUSIONS3D-CT can be used for preoperative design and postoperative assessment in the treatment of oblique facial cleft with mandibular outer cortex.
