Objective To verify the clinical reliability of a simple abrasive method for reduction mandibular osteoplasty.Methods A total of 598 cases of reduction mandibular osteoplasty were performed by using the abrasive method since 2002.Through intraoral incisions,the low part of mandibular ramus,angle region,buucal cortice and inferior border of mandible were exposed and abrasive osteoplasty was taken with special designed retractors,rasp and grinding burs with protecting sheath.The inferior alveolar nerve could be preserved.Results There was no nerve injury and only one hemorrhage case during operation without unfavorable result.In 6 to 1～2 months follow-up for 168 cases,the satisfactory rate for contour results was 95.24%.Conclusion Through the intraoral approach,the abrasive mandibular reduction osteoplasty is a simple,safe and effective method for mandibular osteoplasty.It is not to correct the prominent mandibular angle but to reduce the thickness of the mandibular ramus and body.This method could contribute the same results of angle ostectomy and split cortical bone ostectomy and result a good contour of the jaw region.

Objective:To investigate the value of liver fibrosis serum markers in predicting esophagogastric variceal re-bleeding (EGVR) after laparoscopic splenectomy and azygoportal discon-nection (LSD).Methods:The prospective study was conducted. The clinical data of 155 cirrhotic portal hypertension patients with EGVR after LSD in the Clinical Medical College of Yangzhou University from September 2014 to January 2017 were selected. Observation indicators: (1) grouping situations of the enrolled patients; (2) risk factors analysis for postoperative EGVR; (3) prediction of postoperative EGVR; (4) follow-up. Follow-up was conducted using telephone interview, outpatient examination and hospitalization. Patients were followed up once every 3 months after operation to detect occurrence of EGVR and survival of patient up to January 2018. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data wite skewed distribution were represented as M(range), and comparison between groups was conducted using the non-parameter test. Count data were described as absolute numbers, and comparison between groups were conducted using the chi-square test or Fisher exact probability. Logistic regression model was used for multivariate analysis. The area under curve (AUC) of receiver operating characteristic (ROC) curve was used to estimate the diagnostic efficiency. The Youden index was used to determine the optimal cut-off point. Results:(1) Grouping situations of the enrolled patients. A total of 155 patients were selected for eligibility. There were 106 males and 49 females, aged (53±11)years. Of the 155 patients, there were 21 cases with EGVR in the postoperative 1 year and 134 cases without EGVR in the postoperative 1 year. The protein expression of laminin and collagen Ⅳ were 100.3(range, 16.1?712.2)μg/L and 68.4(range, 35.0?198.8)μg/L in patients with EGVR, vs 35.5(range, 2.0?521.2)μg/L and 43.5(range, 4.3?150.4)μg/L in patients without EGVR, showing significant differences between them ( Z=?4.55, ?4.52, P<0.05). (2) Risk factors analysis for postoperative EGVR. According to the Youden index, the optimal cut-off point of protein expression of laminin and collagen Ⅳ were 64.0 μg/L and 65.0 μg/L, respec-tively. Results of multivariate analysis showed that the protein expression of laminin ≥64.0 μg/L and the protein expression of collagen Ⅳ ≥65.0 μg/L were independent risk factors for postoperative EGVR ( odds ratio=9.69, 8.16, 95 confidence intervals as 3.05?30.82, 2.65?25.15, P<0.05). (3) Prediction of postoperative EGVR. Results of ROC curve showed that the AUC of laminin and collagen Ⅳ in predicting postoperative EGVR was 0.79 (95% confidence interval as 0.66?0.92), with sensi-tivity as 0.62 and specificity as 0.96. (4) Follow-up. All the 155 patients were followed up for 12(range, 1?12)months. During the follow-up, there were 21 of the 155 patients (13.55%) with post-operative EGVR, including 3 cases died of EGVR. Of the 21 patients with postoperative EGVR, there were 6 cases with postoperative EGVR during the first month after operation including 2 cases died, 5 cases with postoperative EGVR at postoperative 1?3 month, 6 cases with postoperative EGVR more than 3 month and less than 6 month after operation and 4 cases with postoperative EGVR at postoperative 6?12 months including 1 case died at postoperative 12 month. Conclusions:Laminin and collagen Ⅳ show satisfactory ability to predict EGVR after LSD.

Objective To observe the effect of BaoShenTongLuo(BSTL)Decoction on diabetic kidney disease and serum inflammatory factors of DKD.Methods A total of 80 DKD patients were collected from patients of Beijing Hospital of Traditional Chinese Medicine.The patients were then randomly divided into control group and treatment group.Patients in control group were received with basic treatment.Patients in treatment group were received with BSTL decoction along with basic treatment.The treatments were lasted for 3 months.Scr,BUN,UACR,24 h proteinuria,MCP-1,TGF-β 1,CRP,IL-6 and TNF-a were detected.Clinical symptom scores of patients in two groups were calculated.Results The total effective rate of treatment group was higher than that in the control group(P<0.05).The scores of TCM symptoms were lower in the treatment group than those in the control group after treatment(P<0.01).Compared with control group,24 h proteinuria,UACR,Scr and BUN was significantly decreased in treatment group after the treatment(P<0.01).After the treatment,the level of MCP-1,TGF-β1,CRP,IL-6 and TNF-α were significantly decreased in treatment group compared with control group(P<0.01).Conclusion BSTL can significantly decrease proteinuria and improved renal function in DKD.More importantly,BSTL can significantly decrease serum inflammatory factors of DKD.
