AIM:To explore the association between single nucleotide polymorphism in exon 33 (E33SNP) of thyroglobulin gene and Graves ’ disease ( GD) relapse after antithyroid drug ( ATD) withdrawal .METHODS:The healthy controls (232 cases) and GD patients with discontinued treatment (243 cases) were selected.According to the time of re-lapse, the GD patients were divided into A, B and C subgroups.The A group contained 77 cases of relapse within 1 year, B group contained 86 cases of relapse 1~2 years after treatment and C group contained 80 cases without recurrence within 2 years.The genotypes of E33SNP were identified by RT-PCR.The genotype ratio of thyroglobulin between control group and observation group was comparatively analyzed , and the levels of thyroid-stimulating hormone ( TSH) , free triiodothyro-nine (FT3), free thyroxine (FT4) and thyrotropin receptor antibody (TRAb), ophthalmopathy and goiter size in A , B and C subgroups in different genotype GD patients were investigated .Moreover , cumulative efficiency for patients with different genotypes in the observation group after ATD treatment within 2 years were analyzed .RESULTS:The genotype of E33SNP between observation group and control group had no significant difference , but a significant difference between A , B and C subgroups was observed (P<0.05).The levels of TSH, FT3 and FT4, and goiter size of the patients with different geno-types had no significant difference , while the TRAb levels and ophthalmopathy presented a significant difference ( P <0.05).In addition, the cumulative efficiency within 2 years for GD patients with E33SNP T/T, E33SNP T/C and E33SNP C/C genotypes was 61.8%, 42.6% and 21.3%, respectively, all with significant differences (P<0.05).CONCLU-SION:The GD patients with E33SNP C/C genotype have significantly higher TRAb level and ophthalmopathy rate than those in the patients with E33SNP C/T and E33SNP C/C genotypes, and are more likely to relapse after ATD treatment . The GD patients with E33SNP T/T genotype show a lower recurrence rate .Therefore, combination treatment or other treat-ment modalities may be more reasonable for the GD patients with E 33SNP C/C genotype.

Objective:To evaluate the efficiency of the tibial coronal alignment after total knee arthro-plasty with the extramedullary cutting system guided by the tibial tubercle and anterior tibial tendon,and to discuss the potential risk factors for the postoperative malalignment.Methods:A retrospective study of 212 primary unilateral TKA surgeries (in 188 patients)in our hospital between June to December in 2014 had been analysed.All the cases were performed by one surgical group.An extramedullary tibial cutting guide system had been used,with a landmark of one third inner-medial tibial tubercle as a proxi-mal anatomy reference,and anterior tibial tendon as a distal marker.The mechanical axis of lower ex-tremity in full-length X-ray was measured before surgery,and the tibial prosthetic coronal alignment was checked two weeks postoperation,evaluating the accuracy of this extramedullary cutting system guided by our method.Results:Since good alignment was defined as an angle within 3 degrees of the perpendicular to the mechanical axis,the tibial component positions were acceptable in 191 knees (90.1%),five knees were in valgus postoperative,and sixteen knees were in varus.There were seventeen(8.7%)in 179 knees with a preoperative varus presented malalignment after surgery,and four in 12 preoperative valgus kneess howed malalignment also,no statistical difference was found by Chi-square test (χ2 =2.778,P=0.096),which cannot define the relationship between the varus or valgus deformity preopera-tion and the malalignmentposition in tibial prosthesis after surgery.Twenty-two knees suffered a severe preoperative deformity as a varus or valgus angle larger than 20 degrees with absolute value of mechanical axis before surgery and tibial prosthetic coronal alignment were 21.95°(20.00°,26.90°)and 1.85° (0.10°,7.10°),showed a significant difference (Z =2.11,P =0.035 )compared with the data [10.65°(0.50°,19.80°)in preoperative mechanical axis and 1.10°(0.00°,4.60°)in the tibial pros-thetic coronal alignment]of 190 knees who presented a mild deformity before surgery(less than 20 de-grees),the result indicated the severe preoperative deformity might be a potential mal-alignment risk fac-tor within this cutting system in TKA surgery.Conclusion:The tibial coronal alignment after total knee arthroplasty could achieve good results with extramedullary cutting guide,by using one third inner-medial tibial tubercle and anterior tibial tendon as a proximal and distal anatomy marker.Postoperative varus might occur in this system,and tibial prosthetic malalignment appeared more often in the patients who suffered a severe deformity before surgery.

Objective:To explore the clinical effect of the second toenail flap with the dorsal bone of the phalange in repairing the defect of fingernail bed.Methods:From January, 2012 to June, 2019, 10 patients with large area of fingernail bed defect were treated by the second toenail flap with bone on the back of the phalanx.

The average follow-up period was 8 (4-12) months. The fractured ends of 10 patients' phalanges healed well without nonunion, good appearance of toenail and deformity of toenail. The recovery of hand function was evaluated according to the evaluation standard of upper limb function of Hand Surgery Society of Chinese Medical Association, 9 cases were excellent, and 1 case was good.Conclusion:The second toenail flap with dorsal bone of the phalanx preserved is easy to cut, simple to operate, and has good clinical effect. It is a good method to repair the defect of the fingernail bed.

The purpose of the study is to explore the in vitro refolding protocol for humanized anti-CTLA4-scFv expressed in E. coli. The inclusion bodies are denatured and then diluted or dialyzed into a refolding buffer. We analyzed several factors affecting the refolding yield, including refolding time, temperature, and redox environment. The refolded target proteins are analyzed by non-reducing SDS-PAGE, and the concentration of refolded proteins are examined by Bio-Rad Dc Protein Assay kit. The result shows that a high yield of the protein with natural conformation can be acquired in the condition of 0.15 mol x L(-1) sodium chloride, 50 mmol x L(-1) Tirs-HCl, pH 8.0 buffer containing 1 micromol x L(-1) reduced glutathione and 3 micromol x L(-1) oxidized glutathione. The refolding time is 48 to 54 h at 4 degrees C. 28 mg refolded proteins are produced from 3.9g E. coli.

Objective To explore the risk factors of post-hepatectomy acute kidney injury (AKI),a Nomogram predictive model of secondary AKI after hepatectomy was established which can provide guidance for the selection of clinically relevant treatment plans and improve the prognosis of surgical patients.Methods A total of 2769 patients who underwent hepatectomy in the Affiliated Hospital of Qingdao University from October 2012 to July 2018 were included in the study.The post-hepatectomy AKI was diagnosed according to the KDIGO AKI criteria in 2012.The selected patients were divided into AKI group (n=133) and non-AKI group (n=2636);they were divided into training group (n=2050) and test group (n=719) according to Enrollment time.The differences of preoperative clinical data,length of hospital stay,and in-hospital mortality between patients with AKI and non-AKI group were compared.The risk factors of post-hepatectomy AKI were evaluated by the Cox regression.A Nomogram predictive model of AKI after hepatectomy was established,and receiver operating curve (ROC) and consistency curve were used to verify the accuracy of the predictive model.Results The incidence of AKI after hepatectomy was 4.80％(133/2769).Compared with non-AKI group,preoperative serum albumin,hemoglobin,and hematocrit levels were lower in AKI group;the level of blood transaminase,total bilirubin,alkaline phosphatase,triglyceride,lactate dehydrogenase,and fibrinogen were higher (P ＜ 0.050);the proportion of preoperative aspirin application was higher (P ＜ 0.001);the duration of operation was longer (P=0.002);the proportion of open surgery was higher (P ＜ 0.001);the mortality rate was higher (P ＜ 0.050);the length of hospital stay was longer (P ＜ 0.050).Cox regression results showed hypertriglyceridemia,hypoalbuminemia,alkaline phosphatase,aspartate aminotransferase,open surgery,lower preoperative glomerular filtration rate,aspirin and duration of surgery were independent risk factors for AKI.We incorporated these indicators into the Nomogram to establish a predictive model for AKI after hepatectomy,the area under ROC curve was 0.764.The area under ROC curve of the test group was 0.781.Conclusion The Nomogram predicting model of AKI after hepatectomy has high accuracy,which is helpful for prognosis of patients who underwent hepatectomy.

OBJECTIVE Histamine is a conserved neuromodulator in mammalian brains and critically involved in many physiological functions.Understanding the precise structure of histaminergic network is the cor-nerstone in elucidating its function.METHODS Herein,using novel HDC-CreERT2 mice and genetic labeling strategies,we reconstructed a whole brain 3D structure of histaminergic neurons and their outputs at 0.32×0.32×2 μm3 pixel resolution with a cutting-edge fluorescence micro-optical sectioning tomography system(fMOST).And we dissect an appetite control circuit originating from the TMN to medial septal nucleus(MS)using fiber photometry,optogenetics,and chemogenetics interfer-ence.RESULTS We quantified the fluorescence density of all brain areas and found that histaminergic fiber density varied significantly among brain regions.The density of histaminergic fiber was positively correlated with the amount of histamine release induced by optogenetic stim-ulation or physiological aversive stimulation.Moreover,we reconstructed fine morphological structure of 60 hista-minergic neurons via sparse labeling,and uncovered the largely heterogeneous projection pattern of individual his-taminergic neuron.Lastly,we found that MS-projecting histaminergic circuit is functionally inhibited during food consumption,and bidirectionally modulates feeding behavior via downstream H2,but not H1,receptors on MS glutamatergic neurons.CONCLUSION Collectively,this study reveals an unprecedented whole-brain quanti-tative analysis of histaminergic projections at the meso-scopic level,providing a foundation for future functional histaminergic study.And we also demonstrate that this MS-projecting histaminergic circuit is critically involved in feeding,and H2Rs in MS glutamatergic neurons is a promising target for treating body weight problems.

Objective To investigate the protective role of Sestrin2 overexpression in hypoxia and re-oxygenation injury (H/R) injury of hippocampal neurons and its mechanism in rats.Methods Neurons were enzymatically isolated from hippocampi of newborn Sprague-Dawley rats (less than 24 h old) and culturedinvitro. These neurons were randomly assigned into 4 groups (n=20) using a random number table: control group, H/R group, vector group and Sestrin2 overexpression group. The hippocampal neurons were seeded in 6-well plates at a density of 2×104 cells/mL; neurons in the latter two groups were transfected with lentiviruses containing empty vector andSestrin2overexpressed genes, respectively; the hippocampal neurons in the later three groups were subjected to oxygen-glucose deprivation (OGD) for 6 h followed by restoration of O2 supply for 20 h. The reactive oxygen species (ROS) content was detected by Reactive Species Assay Kit, and the ATP concentration was detected by ATP Assay Kit. Cell apoptosis rates were measured by flow cytometry. The levels of Sestrin2, dynamin-related protein 1 (Drp1), Fis1, and apoptosis-related proteins Bcl-2, Bax and cytochrome C (Cyt C) were measured by Western blotting. The ratio of Bcl-2 to Bax was calculated. The ultrastructure of mitochondria was observed by transmission electron microscopy.Results As compared with control group, H/R group had significantly lower ATP concentration, Bcl-2 protein expression and ratio of Bcl-2 to Bax ([11.15±0.42] nmol/mg proteinvs. [5.30±0.39] nmol/mg protein; 2.20±0.26vs. 0.91±0.02; 6.46± 0.41vs. 1.04±0.05), statistically higher average fluorescence intensity of ROS and cell apoptosis rate (152.41±17.38vs. 1530.00±14.69; 3.77％±0.74％vs. 56.57％±1.35％), and significantly higher protein levels of Sestrin2, Drp1, Fis1, Bax and Cyt C (0.66±0.06vs. 1.11±0.20; 0.48±0.03vs. 1.16±0.07; 1.14± 0.09vs. 2.47±0.09; 0.34±0.03vs. 0.88±0.04; 0.17±0.03vs. 0.30±0.03,P<0.05); what's more, the structure of mitochondria was obviously destroyed in I/R group. As compared with H/R group, Sestrin2 overexpression group had significantly increased ATP concentration, Sestrin2 and Bcl-2 protein expressions and ratio of Bcl-2 to Bax ([8.95±0.27] nmol/mg protein; 2.67±0.07; 1.80±0.19; 3.95±0.28), significantly lower average fluorescence intensity of ROS and cell apoptosis rate (337.27±15.32; 10.33％±2.60％), and statistically lower protein levels of Drp1, Fis1, Bax and Cyt C (0.43±0.02; 1.11±0.08; 0.45± 0.02; 0.17±0.02,P<0.05); the structure of mitochondria was relatively completed in Sestrin2 overexpression group.Conclusion Sestrin2 overexpression can inhibit mitochondrial fission, reduce accumulation of reactive oxygen species, improve mitochondrial energy metabolism and block mitochondria mediated apoptosis pathway, thereby alleviating I/R injury of rat hippocampal neurons.
