Objective To compare the clinical effects of four kinds of gingival retraction technique in treat-ment of anterior teeth restoration.Methods 169 patients for 352 teeth with tooth body and tooth dentition defect by anterior crown bridge repair were chosen and divided into 4 group by patients'order,including A group(88cases)with single track method,B group(91cases)with single line for two times method,C group(89cases)with double line method and D group(94cases)with double line for two times method.And the fixed restoration satisfaction rate of anterior teeth of both groups was compared.Results The satisfaction rates of gums,shoulder,impression,model and restoration of A group were 73.9%,70.1%,69.3%,65.9%,61.4% respectively,which of B group were 83.5%, 80.2%,80.2%,80.2%,76.9%;which of C group were 84.3%,80.9%,78.7%,77.5%,76.4%;which of D group were 94.6%,93.6%,92.6%,92.6%,90.4%.There were no significant differences in the fixed restoration satisfaction rate of anterior teeth between B group and C group(χ2 =2.43,1.17,2.85,3.04,2.30,all P >0.05). The fixed restoration satisfaction rate of anterior teeth of D group were significantly better than A,B and C groups (χ2 =14.90,16.39,15.83,19.87,21.38,all P <0.05 ).Conclusion Double line for two times method in the treatment of anterior teeth restoration can efficiently avoid ree gingival damage in the situation with abutment shoulder preparation,improve the quality of preparation,impression and model,and are helpful to higher the fitness of the neck of anterior teeth fixed restorations.

Cell swelling activates or upregulates a number of anion channels. Of the volume-activated or-regulated anion channels, the volume-sensitive outwardly rectifying anion channel (VSOR) is most prominently activated and ubiquitously expressed. Volume regulated chloride channels play significant roles in a variety of physiological processes including volume regulation, proliferation, differentiation, migration,apoptosis and resistance of tumor cells. Molecular identification and activation mechanisms of VSOR are poorly understood. Many signaling molecules have been shown to regulate VSOR activity in research, playing permissive or modulatory roles. Therefore, VSOR may be a new anticancer target by identifying its signaling molecules and activation mechanisms.

Objective: The aim of this study was to explore the clinical value of expression levels of serum tumor markers in monitoring the response to the targeted therapy with EGFR-TKI (epidermal growth factor receptor-tyrosine kinase inhibitor) for patients with advanced NSCLC (non-small cell lung cancer). Methods: One hundred and two patients with advanced NSCLC were recruited in this study to receive targeted therapy with oral EGFR-TKI between December 2008 and December 2011. Before treatment and after targeted therapy for two months, the serum tumor markers including CEA (carcinoembryonic antigen), CA125, Cyfra21-1, NSE (neuron-specific enolase) and human SCCAg (squamous-cell carcinoma-related antigen) levels were examined. Meanwhile, the relationship between the changes in expression levels of serum tumor markers and the responses to the targeted therapy evaluated through computed tomography imaging was analyzed. Results: Of 102 patients, no one had CR (complete response), 35 had PR (partial response), 36 had SD (stable disease), and 31 had PD (progressive disease). The patients who had response to the targeted therapy were defined as the patients with CR and PR (response group). The serum CEA level was significantly decreased in the response group (P = 0.007) and increased in the PD group (P = 0.044) after EGFR-TKI treatment, and not significantly changed in the SD group (P = 0.373). After EGFR-TKI treatment, the serum CA125 level in the response group was significantly decreased (P = 0.001), the serum Cyfra21-1 level in the PD group was increased significantly (P = 0.016), and the serum NSE level in the response group was decreased (P = 0.001). The serum SCCAg level did not change significantly (P > 0.05) after treatment in each group. Before treatment, the baseline serum CEA and CA125 levels in the response group were both significantly higher than those in the SD group (P < 0.05) and the PD group (P < 0.05). Conclusion: Detection of a variety of tumor markers, particularly the serum CEA level, contributes to the judgment of therapeutic effect of EGFR-TKI in advanced NSCLC. Significantly higher pre-treatment serum CEA and CA125 levels may predicate the response to targeted therapies. Copyright © 2012 by TUMOR.

RDEA594 could increase the excretion of uric acid to reduce uric acid levels by inhibiting the uric acid salt transport protein 1 (URAT1). In this essay, we summarize synthetic methods of lesinurad reported in recent years, evaluate and analyze them briefly, aiming to lay a foundation for lesinurad synthesis process to achieve industrialization.

Abstract: Objective To analyze the changes of coagulation indicators in patients with hepatitis B complicated with Clonorchis sinensis (C. Sinensis), and provide reference value for diagnosis, drug using and prognosis monitoring. Methods　The patient samples were collected from the Third Affiliated Hospital of Sun Yat-sen University from June 2018 to February 2022 and divided into six groups. They were 40 healthy patients, 47 patients with simple chronic hepatitis B, 47 patients with post-hepatitis B liver cirrhosis, 40 patients with C. Sinensis mono-infection, 30 patients with chronic hepatitis B patients co-infected with C. Sinensis and 27 patients with post-hepatitis B liver cirrhosis patients coinfected with C. Sinensis. Four coagulation indexes, prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT) and fibrinogen (FIB), were detected and compared among the groups. Results Compared with the healthy group, C. Sinensis mono-infection group had higher level of FIB and delayed PT, APTT; chronic hepatitis B group and chronic hepatitis B patients co-infected with C. Sinensis group had delayed PT, APTT, TT and significant lower FIB, these differences were statistically significant (all P<0.05). Compared with simple chronic hepatitis B group, post-hepatitis B liver cirrhosis and chronic hepatitis B patients co-infected with C. Sinensis had significant delayed PT, APTT, TT and lower FIB (all P<0.05). Compared with the post-hepatitis B liver cirrhosis and chronic hepatitis B patients co-infected with C. Sinensis, post-hepatitis B liver cirrhosis patients coinfected with C. Sinensis group had significant delayed PT, APTT, TT and lower FIB (all P<0.05). Conclusions The coinfection of C. Sinensis will further aggravate the coagulation dysfunction of HBV patients, leading to poor treatment and prognosis. HBV patients will have worse coagulation function in the process to post-hepatitis B liver cirrhosis; Therefore, it is important to pay attention to C. Sinensis co-infection when treating HBV patients, so that further guidance on clinical use and monitoring of prognosis can be provided.

Objective To evaluate remedy therapy for biliary restenosis after repair of bile duct injury.Methods Clinical data of 60 patients with bile duct injury including 16 patients with restenosis after repair admitted to Renji Hospital affiliated to Shanghai Jiaotong University School of Medicine from January 2000 to December 2012 was retrospectively analyzed.Results 16 patients suffering from biliary duct restenosis included 3 cases of type Ⅱ 1 d,10 cases of type Ⅱ2 d,2 cases of type Ⅱ 3 d and 1 case of type Ⅱ 4 d.The reoperative procedures included hepatic hilar biliary plasty with bilioenteric anastomosis in 15 cases,right hemihepatectomy with left hepatic bilioenteric anastomosis in 1 case.Postoperative bile leakage in 3 cases and pleural effusion in 10 cases were cured by watchful therapy.All of the 16 cases were followed up with an average time of 5.2 years.No occurrence of cholangitis and elevated liver enzymes were observed up to now in 8 patients,increased γ-GT and ALP,no cholangitis but anastomotic stenosis as showed by MRCP in 6 patients with 2 patients neccesitating reoperation to address repeated cholangitis.Conclusions Restenosis after bile duct repair was closely associated with injury type,repair opportunity,repair methods and the surgeon's expertise.Precise preoperative evaluation,the choice of rational surgical approach,the clinging to mucosa-to-mucosa bilioenteric anastmosis principle and the establishment of postoperative long-term followup system centered on ALP,γ-GT and life quality score are required in the reoperation of stenosis after bile duct repair.

Objective To investigate the manifestation strategies of emotional labor and current status of emotional intelligence,further to discuss their correlation. Methods Investigation was carried out in 341 nurses by emotional labor scale(El.S) and emotional intelligence scale(EIS) and the results underwent analysis. Results In the aspect of emotional labor,nurses preferred natural manifestation instead of surface manifestation strategy.Nurses had strong ability of understanding and emotional control (P＜0.01) but weak perceptual emotional ability(P＜0.01).Emotional intelligence had higher predictive power for natural and inner presentation(P＜0.01),but was no related with surface manifestation(P＞0.05). Conclusions Different correlation existed between various manifestation strategies of emotional labor and emotional intelligence.Improvement of emotional intelligence can facilitate the application of natural manifestation and inner presentation.

OBJECTIVETo observe the effect of Yijing Recipe (YR) on the apoptosis of testis spermatogenic cells and the protein expression of Bcl-2/Bax in rats with adenine induced infertility.

METHODSTotally 75 Wistar rats were randomly divided into 5 groups, i.e., the blank control group, the model group, the high dose YR group, the middle dose YR group, and the low dose YR group, 15 in each group. Except those in the blank control group, rats in the rest groups were intragastrically administered with adenine for 10 successive days. From the 11th day, rats in the blank control group and the model group were fed with equal volume of normal saline. Rats in the YR groups were intragastrically administered with YR at different doses (3.38 g/100 g; 1.69 g/100 g; 0.85 g/100 g), once daily for 20 consecutive days. All rats were killed by the end of the experiment and their testes extracted. The apoptosis of spermatogenic cells and the expression of Bcl-2/Bax proteins were detected by terminal deoxynucleotidyl transferase-mediated biotinylated UTP nick end labeling (TUNEL) and SABC method.

RESULTSCompared with the blank control group, the Bcl-2 protein expression decreased, the Bax protein expression increased, and the apoptosis index increased in the model group, showing statistical difference (P <0.01). Compared with the model group, the Bcl-2 protein expression increased in the three YR treated groups (P <0.01, P <0.05). The Bax protein expression level decreased in the high and middle dose YR groups (P <0. 01, P <0. 05). The apoptosis index decreased in the middle dose YR group (P <0.01).

CONCLUSIONYR could inhibit the apoptosis of spermatogenic cells through regulating the expression of Bcl-2 and Bax protein in the testis.
