Objective:To identify the risk factors of anxiety disorders among patients undergoing coronary angiography (CAG) and to determine whether the decision of revascularization affect anxiety level following coronary angiography.
Methods:A total of 379 patients undergoing CAG in Fuwai Hospital from Dec. 2012 to Dec. 2013 were invited to participate this study. A data-collecting form, which included questions about demographic features, health history, Type A Behavior Questionnaire (TABQ) and Self Rating Anxiety Scale (SAS), was completed by the participants on the day before and the day after CAG.
Result:Among these patients, SAS score of both before and the day after CAG were higher than Chinese normative SAS score. Female patients had a higher SAS score level than male patients (40.57±9.53 vs 38.26±9.61, P<0.05) before CAG. Patients with these factors of female, over 50 years old, duration of coronary artery disease over 1 year, lower education level had a higher SAS score after CAG. SAS score declined signiifcantly after CAG except those scheduled to receive CABG. Multivariable linear analysis found the D-value between SAS scores before and after CAG was negative correlated with degree of education and positive correlated with the duration of coronary artery disease.
Conclusion:The anxiety level decreased after CAG, except those who need coronary revascularization surgery.

Objective To conclude and compare the technical characteristics and clinical efficacy of retroperitoneal and transperitoneal approach for robotic partial nephrectomy.Methods 418 patients received robotic partial nephrectomy conducted by one surgeon in the urology department of PLA General Hospital from 2013, December to 2015, October, including 157 cases in retroperitoneal approach and 261 cases in transperitoneal approach.There were no significant difference between the transperitoeal and retroperitoneal approach in patient age(51 years, 51 years, P=0.593), BMI(25.5 kg/m2,25.6 kg/m2, P=0.331), gender(male/female:111/46,186/75,P=0.184), location(left/right,80/77,123/138,P=0.575), tumor size(3.1cm,3.5cm,P =0.356), comorbidities, proportion of solitary kidney(11.5%, 9.6%,P=0.253) or bilateral tumors(1.3%,3.4%,P=0.179), RENAL score(6(5-8),6(5-8),P=0.083), ASA score(2 vs.2)(P=0.310) and preoperative serum creatinine(74.7 μmol/L,76.7 μmol/L, P=0.736).Patients in the retroperitoeal approach group were more likely to have abdomen surgery history (21.7%,14.2%,P=0.049).there was significant difference between two approaches in tumor location in the kidney ( anterior/posterior/others: 9/140/8, 212/36/13, P <0.001 ) Results The operation time (105min, 115min, P =0.041 ) and warm ischemia time ( 15min, 20min, P <0.001 ) were shorter and estimated blood loss(50ml,75ml,P<0.001) was less in the retroperitoneal group.No significant difference was observed in postoperative 24h blood loss(45ml,50ml,P =0.093), intraoperative transfusion rate (2.5%,6.5%,P=0.072) and collective system injury(24.8%,27.6%,P =0.539) between the two groups.Peritoneum break occurred in 25 cases in retroperitoneal group, which were repaired by Hem-o-lock.One intestinal injury occurred in transperitoneal group and was repaired intraoperatively.Three and nine cases in the retroperitoneal and transperitoneal group were converted to radical nephrectomy.One case in the transperitoneal group was found positive margin and received laparoscopic radical nephrectomy.Two liver injury and five spleen injury occurred in the transperitoneal group.For postoperative food intake(1 day, 2 days, P <0.001 ) , the length of indwelling drainage ( 3 days, 4 days, P <0.001 ) and the length of postoperative stay ( 5 days, 6 days, P =0.001 ) , the retroperitoneal group had one day shorter than the transperitoneal group.With the median following-up time of both group, 11 months (IQR:6-16) in RPRPN group and 12 months ( IQR: 7-19 ) , no subject with a tumor recovery or metastasis.Conclusions Retroperitoneal robotic partial nephrectomy is feasible and effective, which is similar to transperitoneal approach.The retroperitoneal approach is superior to transperitoneal approach for posterior, lateral and superior renal tumors.

Objective To evaluate the key technique and effectiveness of potency preservation in robotic-assisted laparoscopic radical prostatectomy (RALP).Methods The complete clinical and follow-up data of 30 cases underwent RALP between February and May of 2016 were reviewed retrospectively.The average age of the patients was 67.3 years (48-82 years).The peak PSA level before surgery ranged from 7.6 to 53.4 ng/ml with the average level of 21.1 ng/ml.There were 7,16,6 and 1 case with the Gleason score of 6,7,8,and 9 point,respectively.Preoperative erectile score (IIEF-5) of the 30 patients were list as below:3 cases (0-10 points),4 cases(11-15 points),17 cases(16-20 points),and 6 cases(21-25 points).The key techniques of potency preservation during RALRP includes deep dorsal vein ligation techniques,neurovascular bundles preservation techniques and drain tube placement techniques.Results All 30 cases underwent operation successfully with no transfer to open surgery.Average operative time was 150.7 min (98-240 min) with an estimated blood loss of 165.7ml (50-550 ml).The average drainage removal time was 5.1 d postoperatively.The average bowel recovery time was 2.7 d and average hospitalization time was 8.2 d,respectively.There were two cases with one positive margin on the bladder neck and one on the tip of prostate,respectively.Seventeen cases gained potency preservation six months after surgery.Conclusion It was safe and beneficial for the potency preservation in RALP,which could be considered as one of the best options for the prostate cancer surgery.

Objective To investigate the in vitro effects of bladder cancer cell proliferation after silencing Notch1 gene. Methods The siRNA eukaryotic expression vector of Notch1 (psiRNA1)was constructed and transfected into bladder cancer cell lines T24 and BIU-87. Methabensthiazuron (MTT) and flow cytometry (FCM) assays were used to detect bladder cancer cells line growth, cell cycle and apoptosis after the transfection. RT-PCR and Western blotting were used to determine the expression changes of Notch1 in these cell lines. Results After transfection for 72 h, the rate of G0/G1 phase cells inceased from (23.89±1.32) % to (80.13±2.69)% in T24 cell line, and increased from (24.63±1.68)% to (69.44±2.41)% in BIU-87 cell line (both P<0.05). In addition, apop-totic cell index in T24 and BIU-87 cell lines increased from (1.28±0.14)% to (13.75±1.23)%, from (1.01±0.27)% to (8.72±1.01)%, respectively(both P<0.05). The growth of T24 and BIU-87 cell lines was obviously inhibited 24 h after the transfection, and the inhibitory effects lasted until 96 h after the transfection. Notch1 mRNA and protein significantly downregulated after transfection compared to the control(P<0.05). Conclusions Silencing Notch1 expression can inhibit the prolif-eration of bladder cancer cell lines. Notch1 gene might act as a tumor gene in bladder cancer.

Objective: To evaluate the effectiveness for the construction of "mosquito-free village" in Xuejia Village, Pujiang County, Zhejiang Province, so as to provide the guidance for the construction of "mosquito-free village" in other rural areas. Methods: Density of adult mosquitoes in Xuejia Village was investigated using light trap method and density of larval mosquitoes was investigated using larval straw method from April to November each year. Totally 30 households of villagers were randomly selected, and their awareness rates of mosquito control knowledge, mosquito control behavior forming rates and satisfaction rates were surveyed through questionnaires. Investment during construction (from August 2016 to December 2018) and maintenance period (from 2019 to 2023) of "mosquito-free village" were investigated through data review and interviews. Long-term effects of "mosquito-free village" construction in Xuejia Village were evaluated in terms of mosquito density from 2016 to 2023, effectiveness of health education for villagers, satisfaction and investment. Results: Compared with the year 2016, the densities of adult and larval mosquitoes in Xuejia Village were significantly decreased from 2017 to 2023. The average monthly density of adult mosquitoes in 2023 decreased by 98.34%, and the average monthly 100 household index of larval mosquitoes decreased by 98.45% compared to 2016. The average monthly density of adult mosquitoes from 2019 to 2023 was less than or equal to one mosquito per light trap in a night, and the average monthly 100 household index of larval mosquitoes was less than or equal to five places per 100 households. The awareness rate of mosquito control knowledge was 93.33%, the behavior forming rate was 86.67%, and the satisfaction rate was 90.00%. By December 2023, the total investment during construction and maintenance period was 450 thousand Yuan, with an average annual investment of 60.7 thousand Yuan and average annual investment of 206.61 Yuan per household. The average annual investment during maintenance period was 36.2 thousand Yuan, and the average annual investment per household was 109.70 Yuan. Conclusion The mosquito density, effectiveness of health education for villagers and satisfaction of "mosquito-free village" in Xuejia Village all meet the evaluation criteria of "mosquito-free village", and the investment is reasonable, making it suitable for promotion to other rural areas.

Objective To determine the association of mutations in aldosterone synthase (CYPllB2)and 11 beta-hydroxylase(CYP11B1)genes with primary aldosteronism(PA).Methods Five mutations of CYP11B2 and CYP11B1 genes were analyzed in patients with PA and normal population.Among them,intron 2 was detected by 2 independent PCR reactions,and the others were analyzed using Taqman probes.The Haploview 4.0,SNPassoc 1.5-3 and Haplo.stats 1.3.8 were used to analyse the association between polymorphisms and PA.Results All the selected mutations were successfully genetyped.Only rs64lO allelic frequencies in patients with aldosterone-producing adenoma (APA)and idiopathic hyperaldosteronism(IHA)were significantly different with those in controls (P＜0.05).There was a relative excess of AA homozygotes and AG heterozygotes of rs6410 allele in APA group compared with control group(P＜0.01).There were significantly different genotypes AA and AG of rs6410 allele between patients with IHA and controls only after adjusted for age,gender,eeptible haplotype AAAWT was identified to be significantly associated with APA(OR=1.44,95%CI 1.19-1.76).Three susceptible haplotypes AAAWT,AGGWT and AGAWC were identified to be significantly associated with IHA(OR=1.55,95%CI 1.23-1.96;OR=1.49,95%CI 1.17-1.89;OR=1.40,95%CI 1.04-1.88).In contrast,1 protective haplotype GGAWT showed significant difference between patients with APA and controls(OR=0.73,95%CI 0.55-0.97).Conclusion There is a significant association between genetic variations in CYP11B2 and CYP11B1 genes and genetie predisposition to PA.

Objective: To assess the safety and effectiveness of sufficient, short-term platelet (PLT) transfusion for the surgery preparation of the infantile patients with Kasabach-Merritt phenomenon, who were insensitive to glucocorticoids. Methods: The infantile cases were retrospectively analyzed during May 2011 to December 2016, who were clinically diagnosed as KMP and insensitive to glucocorticoids, received PLT transfusion and surgical resection. PLT transfusion in patients whose PLTC was less than 30×10⁹/L, was 0.3 therapeutic dose(TD)/kg, and 0.2 TD/kg in PLTC≥30×10⁹/L group. The maximum was 1 TD.Criteria of the PLT transrusion: 1 hour after the transfusion, the PLT count (PLTC) were tested and the corrected count increment of platelet (CCI) and practical platelet recovery (PPR) was calculated. PLTC ≥100×10⁹/L, CCI>7.5×10⁹/L and PPR>30% were defined as effective; while PLTC=(50-99)×10⁹/L, CCI>7.5×10⁹/L and PPR>30% as partial effective; PLTC<50×10⁹/L, or CCI≤7.5×10⁹/L, or PPR ≤30% were defined as ineffective. By reviewing the method and response of their PLT infusions, to figure out the most effective way in rising PLT, as a part of pre-operation treatment. Results: There were 46 cases in the research. Based on the PLTC, CCI and PPR 1 hour after PLT transfusion, there were 44 effective transfusion, 2 patients with partial effectiveness, and no ineffective case. There was no allergic or heart failure happened in any cases. No critical potential complications of PLT transfusion occurred, including fluid and iron overload, alloimmunization to human leukocyte antigen and/or PLT antigen. Conclusions Pre-operative sufficient and short-term PLT infusions are more effective than low dose and long-term ones. They can create a more optimistic opportunity for surgical resections.

It was a retrospective cohort study. Patients diagnosed with idiopathic membranous nephropathy (IMN) and received rituximab (RTX) alone for one course of treatment during hospitalization in the Department of Nephrology of the First Hospital of Jilin University from March 2020 to March 2022 were enrolled. The patients were divided into 1 g standard treatment group (once 1 g every 2 weeks for twice) and 375 mg/m 2 experimental treatment group (375 mg/m 2 once a week for 4 weeks) according to the different methods of drug administration, and the efficacy and safety of different doses of RTX in the treatment of IMN were compared between the two groups to provide a reference for optimizing the clinical treatment protocol. The patients were followed up regularly for more than 9 months after treatment and the data were complete. A total of 69 patients were included with age of (51.7±11.8) years old, and 46 males (66.7%). There were 31 patients in the 1 g standard treatment group and 38 patients in the 375 mg/m 2 experimental treatment group. The proportion of first-treatment patients in the 1 g standard treatment group was higher than that in the 375 mg/m 2 experimental treatment group (87.1% vs. 65.8%, χ2=4.174, P=0.041). There were no statistically significant differences in the general data, clinical characteristics and baseline laboratory parameters between the two groups (all P>0.05). At the end of 3 months of treatment, 22 patients (31.9%) experienced remission, including 9 patients (29.0%) in the 1 g standard treatment group and 13 patients (34.2%) in the 375 mg/m 2 experimental treatment group ( χ2=0.211, P=0.646). At 6 months, 30 patients (43.5%) experienced remission, including 12 patients (38.7%) in the 1 g standard treatment group and 18 patients (47.4%) in the 375 mg/m 2 experimental treatment group ( χ2=0.521, P=0.470). At 9 months, 38 patients (55.1%) achieved remission, including 18 patients (58.1%) in the 1 g standard treatment group and 20 patients (52.6%) in the 375 mg/m 2 experimental treatment group ( χ2=0.204, P=0.652). At 9 months, the 24 h urine protein of 1 g standard treatment group and 375 mg/m 2 experimental treatment group decreased by 7.93 (6.24, 8.46) g and 7.45 (5.66, 8.67) g (both P<0.05), respectively, and serum albumin increased by 16.4 (15.5, 17.5) g/L and 15.5 (9.0, 15.8) g/L (both P<0.05), respectively, from the baseline value. Kaplan-Meier survival analysis result showed that there was no significant difference in the time of phospholipase A2 receptor titer decreasing to <5 RU/ml between the two groups (Log-rank χ2=3.653, P=0.056). Twenty-three non-serious adverse events occurred in the 1 g standard treatment group, involving 16 patients, and 10 non-serious adverse events occurred in the 375 mg/m 2 experimental treatment group, involving 10 patients. There was better safety in the 375 mg/m 2 experimental treatment group than that in the 1 g standard treatment group ( Fisher value=8.593, P=0.015). Both 375 mg/m 2 regimen and 1 g regimen of RTX in IMN patients are effective in relieving proteinuria and elevating serum albumin. The 375 mg/m 2 regimen of RTX has a lower incidence of adverse events compared with the 1 g regimen.

Objective:To investigate the modulatory function of interleukin-7 (IL-7)/CD 127 signaling pathway on CD 8+T cells in patients with myasthenia gravis (MG). Methods:Fifty-seven treatment-naive MG patients who were hospitalized in Department of Neurology, Nanyang Central Hospital between 2017 and 2020 as well as 35 healthy controls were enrolled. Peripheral blood was collected, while plasma and peripheral blood mononuclear cells were isolated. Plasma IL-7 and soluble CD 127 (sCD 127) were measured by enzyme linked immunosorbent assay (ELISA). Membrane-bound CD 127 (mCD 127) percentage in CD 8+T cells was measured by flow cytometry. The differences of above indices between different gender, onset age, afflicting with thymoma, or different Osserman type and their correlation with Quantitative Myasthenia Gravis (QMG) score were analyzed. Purified CD 8+T cells from MG patients were stimulated with recombinant human IL-7 (5 μg/L). Changes of sCD 127 and mCD 127 level were analyzed. Levels of perforin, granzyme B, interferon-γ (IFN-γ), and tumor necrosis factor-α (TNF-α) in the cultured supernatants were measured by ELISA. Immune checkpoint molecules mRNA in CD 8+T cells was semi-quantified by real-time fluorescence quantitative polymerase chain reaction. Results:Plasma IL-7 level was up-regulated in MG patients compared with controls [(293.4±74.7) pg/ml vs (233.8±70.8) pg/ml, t=3.78, P<0.001], while sCD 127 level was down-regulated in MG patients compared with controls [(102.7±13.7) pg/ml vs (131.2±20.9) pg/ml, t=7.91, P<0.001]. Peripheral CD 8+T cells percentage was up-regulated in MG patients compared with controls (35.4%±7.1% vs 30.2%±7.5%, t=3.31, P=0.001), and mCD 127+CD 8+T cell percentage was also elevated (45.5%±7.7% vs 34.7%±11.5%, t=5.44, P<0.001). There were no significant differences of above indices between different gender, onset age, afflicting with thymoma, or different Osserman type. There was no significant correlation between above indices and QMG score. There were no significant differences of sCD 127 in cultured supernatants, mCD 127+CD 8+T cell percentage, or immune checkpoint molecules mRNA expression between CD 8+T cells from MG patients with and without IL-7 stimulation. IL-7 stimulation promoted the secretion of perforin [(208.1±67.2) pg/ml vs (168.8±46.2) pg/ml, t=2.16, P=0.038], granzyme B [(941.8±273.9) pg/ml vs (782.4±137.2) pg/ml, t=2.33, P=0.025], and IFN-γ [(19.1±5.2) pg/ml vs (15.3±4.5) pg/ml, t=2.47, P=0.018] by CD 8+T cells. However, there was no remarkable difference of TNF-α production between CD 8+T cells with and without IL-7 stimulation. Conclusion:Elevated IL-7-mediated signaling pathway enhanced the secretion of cytotoxic molecules and cytokines by CD 8+T cells, leading to increased activity of CD 8+T cells in MG patients.

Objective To explore the feasibility of robot-assisted laparoscopic inferior vena cava (IVC) thrombectomy in treating renal tumor with Mayo level Ⅲ-Ⅳ inferior vena cava thrombus.Methods From November 2014 to January 2017,5 cases of renal tumor with Mayo level Ⅲ-Ⅳ inferior vena cava tumor thrombus were treated with robot-assisted surgery.There were 4 males and 1 female with the median age of 59 years (range 54-71 years).Four cases had the renal tumor on the right side and one on the left side.The mean tumor size was 6.8 cm (range 5-9 cm) with 3 cases of T3b and 2 cases of T3c.There were 4 cases of level Ⅲ and 1 case of level Ⅳ inferior vena cava thrombus with the median length of 9 cm (range 7-11 cm).The surgical procedure for Mayo level Ⅲ inferior vena cava thrombus included mobilization of both left and right robes of liver,subsequently controlling the suprahepatic infradiaphramatic IVC and first porta hepatis simultaneously.The surgical procedure for Mayo level Ⅳ inferior vena cava thrombus included cardiopulmonary bypass by multi-disciplinary cooperation among urologists,hepatobiliary and cardiovascular surgeons.The procedures included live mobilization,control of the superior vena cava and first porta hepatis and remove thrombus in the atrium and IVC respectively.Results All operations were completed successfully.The median operative time was 440 min (320-630 min).The blood recovery device was used and the intraoperative estimated blood loss was 2 500 ml (500-6 000 ml) and all cases required intraoperative blood transfusion.The median time of intraoperative occlusion of IVC was 35 min (25-50 min).All patients were transferred to the intensive care unit for median of 4 days (2-8 days) after surgery.The median time to remove the postoperative drainage tube was 9 days (7-12 days).Postoperative pathological diagnosis revealed 5 cases of clear cell carcinoma.Postoperative renal dysfunction occurred in 3 patients and liver dysfunction occurred in 2 patients who improved after medical therapy.During median 19.6 months (12-48 months) of follow-up,1 patient died and 1 patient progressed.Conclusions Despite the high risk of surgery,robot-assisted laparoscopic IVC thrombectomy for renal tumor with Mayo level Ⅲ-Ⅳ thrombus is feasible for experienced surgeons in selected patients.However,the oncological outcomes need further investigation.
