Objective To investigate the causes , surgical methods and complications of reoperation of thyroid carcinoma and management .Methods Clinical data of patients with thyroid carcinoma in Department of General Surgery of Tang Du Hospital during Jan .2007 to Apr.2012 were retrospectively analyzed .The causes and complications were studied.Results Postoperative complications happened to 5 cases(13.51%), among whom 2 cases had temporary recurrent laryngeal nerve palsy and they recovered after 2 to 6 months , 2 cases had temporary hypocalcemic convulsions and the symptom resolved after one-week treatment with intravenous calcium gluconate , and 1 case had bucking and recovered after one week of treatment .Conclusion For patients with thy-roid disease,detailed preoperative examination , intraoperative frozen pathological examination , intraoperative explo-ration and the right operation method are the key factors to prevent thyroid carcinoma reoperation .Careful dissection and gradually sever of upper pole of thyroid lobe reduce complications of thyroid carcinoma reoperation .

Little is known about the effects of chronic alcohol intake on the outcome of acute kidney injury (AKI). Hence, we examined the effects of chronic alcohol intake on the development of renal fibrosis following AKI in an animal model of bilateral renal ischemia–reperfusion (IR) injury. We first found that chronic alcohol exposure exacerbated bilateral IR-induced renal fibrosis and renal function impairment. This phenomenon was associated with increased bilateral IR-induced extracellular matrix deposition and an increased myofibroblast population as well as increased bilateral IR-induced expression of fibrosis-related genes in the kidneys. To explore the mechanisms underlying this phenomenon, we showed that chronic alcohol exposure enhanced β-arrestin 2 (Arrb2) expression and Akt and glycogen synthase kinase-3 (GSK3)β activation in the kidneys. Importantly, pharmacological GSK3 inhibition alleviated bilateral IR-induced renal fibrosis and renal function impairment. Furthermore, we demonstrated that Arrb2(−/−) mice exhibited resistance to IR-induced renal fibrosis and renal function impairment following chronic alcohol exposure, and these effects were associated with attenuated GSK3β activation in the kidneys. Taken together, our results suggest that chronic alcohol exposure may potentiate AKI via β-arrestin 2/Akt/GSK3β-mediated signaling in the kidney.

OBJECTIVETo compare the short-term safety and costs between laparoscopic assisted or totally laparoscopic uncut Roux-en-Y and Billroth II((BII() + Braun reconstruction after radical gastrectomy of distal gastric cancer.

METHODSClinical data from our prospective database of radical gastrectomy were systematically analyzed. The patients who underwent laparoscopic gastrectomy with uncut Roux-en-Y or BII(+ Braun reconstruction between March 1st, 2015 and June 30th, 2017 were screened out for further analysis. Both the reconstructions were completed by linear staplers. Uncut Roux-en-Y reconstruction was performed with a 45 mm no-knife linear stapler (ATS45NK) on the afferent loop below the gastrojejunostomy. Continuous variables were compared using independent samples t test or Mann-Whitney U. The frequencies of categorical variables were compared using Chi-squared or Fisher exact test.

RESULTSEighty-one patients were in uncut Roux-en-Y group and 58 patients were in BII(+Braun group. There were no significant differences between uncut Roux-en-Y group and BII(+Braun group in median age (56.0 years vs. 56.5 years, P=0.757), gender (male/female, 52/29 vs. 46/12, P=0.054), history of abdominal surgery (yes/no, 10/71 vs. 4/54, P=0.293), neoadjuvant chemotherapy (yes/no, 21/60 vs. 11/47, P=0.336), BMI (thin/normal/overweight/obesity, 2/49/26/3 vs. 3/39/14/2, P=0.591), NRS 2002 score (1/2/3/4, 58/15/5/3 vs. 47/5/3/3, P=0.403), pathological stage (0/I(/II(/III(, 3/41/20/17 vs. 1/28/13/16, P=0.755), median tumor diameter in long axis (2.5 cm vs. 3.0 cm, P=0.278), median tumor diameter in short axis (2.0 cm vs. 2.0 cm, P=0.126) and some other clinical and pathological characteristics. There were no significant differences between uncut Roux-en-Y group and BII(+Braun group in morbidity of postoperative complication more severe than grade I([12.3% (10/81) vs. 17.2% (10/58), P=0.417], morbidity of anastomotic complication [1.2%(1/81) vs. 0, P=1.000] or hospitalization costs [(94000±14000) yuan vs.(95000±16000) yuan, P=0.895]. The median first time to liquid diet (57.1 hours vs. 70.8 hours, P=0.017) and median postoperative hospital stay (9 days vs. 11 days, P=0.003) of the patients in uncut Roux-en-Y group were shorter than those in BII(+Braun group.

CONCLUSIONLaparoscopic assisted or totally laparoscopic uncut Roux-en-Y reconstruction after radical gastrectomy of distal gastric cancer is safe and feasible with better recovery than BII(+Braun reconstruction.

Lyotropic liquid crystal is an ordered system with various geometric shapes or three-dimensional structures formed by the interaction of amphiphilic molecules dissolved in polar solvents, and has the characteristics of excellent drug applicability, high drug loading, good bioadhesive property and high transdermal permeability. Through a comprehensive analysis of the research results in this research group and the related research reports of LLC drug delivery system, the authors systematically discussed the research value, development potential and research status of LLC in the field of new drug delivery system of traditional Chinese medicine(TCM), especially in the percutaneous and mucosal drug delivery system and the oral microparticle drug delivery system of TCM. At the same time, due to the current research field of TCM-LLC drug delivery system starts late, many of the basic research problems to be further perfect, this paper had carried on the induction summary to these problems, and put forward the research countermeasures:①the basic research of TCM-LLC drug delivery system should be strengthened by referencing the research experience and methods of LLC drug delivery system of single chemical component combined with TCM characteristics, ②the research on the release mechanism of the chemical components in TCM should be strengthened, and the basic research on the LLC drug delivery system of synchronized sustained release TCM should be carried out, ③development of new LLC materials applicable to TCM, ④the quality evaluation system of TCM-LLC should be improved, ⑤to explore the LLC preparation process suitable for industrialization.
