Objective To investigated the significance of serum B7-H3 in differential diagnosis of patients with benign and malignant obstructive jaundice.Methods The B7-H3 levels in 60 patients with obstructive jaundice who were divided into benign (32 patients) and malignant (28 patients) obstructive jaundice group were tested by enzyme-linked immunosorbent assay before and after operation.Results The serum B7-H3 levels of malignant obstructive jaundice group were significantly higher than that of benign group (9334.57 ± 1009.57) pg/mL vs (4450.81 ± 406.92) pg/mL,(P ＜ 0.01).The B7-H3 levels of benign and malignant obstructive jaundice group after operation were significantly lower than those before operation (2531.03 ± 415.64) pg/mL vs (4450.81 ±406.92) pg/mL,(5833.00 ± 2190.87) pg/mL vs (9334.57±1009.57) pg/mL,(P＜0.01).Conclusion B7-H3 participate in the inflammatory immune and tumor immune response,The serum B7-H3 can be used as differential diagnosis index of benign and malignant obstructive jaundice.

Objective To explore a better method in obtaining iris pigment epithelium (IPE) specimen for autologous transplantation in rabbits. Methods IPE was obtained from 20 black rabbits with method A, i.e., surgical peripheral iridectomy at 12:00 position obtaining a triangle iris tissue with the hemline of 4-5 mm in left eyes,and method B,i.e., surgical peripheral iridectomy at 11:00 and 1:00 positions obtaining two triangle iris tissues with the hemlines of 2-2.5 mm in right eyes . The IPE cells were isolated precisely with enzyme microdissection-enzyme isolation method, cultured in vitro, observed with light and electronic microscope, and identified with immunocytochemical staining. Results The success rate of cells culture were 65% for method A and 95% for method B. After 3-4 generations of culturing,the amount of IPE cells was enough for transplantation, and most of the functions of primary clutured IPE cells were kept still. Viability of IPE cells was 85%-93%. Conclusion The success rate of cells culture for method B is higher than that for method A. The third generation of cultured cells is available for autologous transplantation.

Antiangiogenic therapy is an essential approach in the treatment of malignant tumors along with the development of preci-sion medicine. However, the occurrence of antiangiogenic therapy-induced hypertension, which is the most common toxicity of this agent, influences its broad clinical use (in some cases). Researches on its mechanisms, prevention, and management, have been con-ducted, but clinical guidelines or expert consensuses have not been reached. In this review, we presented the epidemiology, current re-search status, and systematic management of antiangiogenic therapy-induced hypertension.

Objective To evaluate the effect of single hand pipe method on venous indwelling needle puncture. Methods Literature about the impact of single hand pipe method on venous indwelling needle puncture was retrieved from digital databases of PubMed, Medline, EMbase, The Cochrane Library, SinoMed, VIP database, China National Knowledge Infrastructure(CNKI), and WanFang Data. The quality of literature was evaluated by the Cochrane Handbook (5.1.0). The Meta data was analyzed by RevMan 5.3. Results Ten random control trials were included . Ten studies indicated that single hand pipe method increased success rate of puncture[related to the risk(RR)=1.16, 95%confidence interval(CI) 1.11-1.22]. And, it decreased the complication rate (3 studies) (RR=0.32, 95%CI 0.13-0.79) and pain rate(2 studies) (RR=0.25, 95%CI 0.13-0.47) as well as shorten the time of tube(2 studies) (WMD:-1.68, 95%CI-2.44--0.93). Conclusions Single hand pipe method can improve a puncture success rate and reduce complications and pain rate and shorten the time of tube, so that get more time to rescue the patient, and improve the level of the working efficiency and nursing for the nursing staff. In addition, to some extent, save manpower. It is worth being popularized.

Objective:To investigate the efficacy of Xiaoer Jinqiao granule combined with interferon α-2b on acute herpangina in children and its effect on immune function and myocardial enzyme. Methods:A total of 102 children with acute herpangina who received treatment in Hangzhou Ninth People's Hospital from January 2019 to January 2020 were randomly assigned to receive treatment with either interferon α-2b (control group, n = 51) or Xiaoer Jinqiao granule combined with interferon α-2b (observation group, n = 51) for 5 d. The time to disappearance of main symptoms, changes in humoral immune function, changes in cellular immune function and myocardial enzyme level after treatment relative to before treatment as well as curative effect were compared between the control and observation groups. Results:The time to disappearance of pharyngeal herpes [(3.05 ± 0.74) d], salivation [(2.31 ± 0.68) d], and fever [(1.36 ± 0.39) d] in the observation group were significantly shorter than those in the control group [(4.38 ± 0.98) d, (3.83 ± 1.07) d, (2.54 ± 0.71) d, t = 7.773, 8.562, 10.403, all P < 0.05]. After treatment, serum IgA [(1.49 ± 0.16) g/L], IgG [(10.29 ± 0.89) g/L] and IgM [(1.26 ± 0.14) g/L] levels in the observation group were significantly higher than those in the control group [(1.13 ± 0.12) g/L, (9.35 ± 0.72) g/L and (0.98 ± 0.13) g/L, t = 12.855, 5.864 and 10.466, all P < 0.05]. After treatment, CD 3+ [(74.29 ± 2.15)%], CD 4+ [(40.85 ± 1.65)%] and CD 4+/CD 8+ expression [(1.87 ± 0.23)] in the observation group were significantly higher than those in the control group [(67.96 ± 2.43)%, (38.02 ± 1.20)% and (1.49 ± 0.14), t = 13.933, 9.906 and 10.079, all P < 0.05]. After treatment, serum creatine kinase [(147.86 ± 15.42) U/L] and lactate dehydrogenase [(128.64 ± 14.25) U/L] in the observation group were significantly lower than those in the control group [(176.95 ± 13.15) U/L and (184.32 ± 18.98) U/L, t = 10.251, 16.754, both P < 0.05]. Total effective rate in the observation group was significantly higher than that in the control group [92.16% (47/51) vs. 74.51% (38/51), χ 2 = 5.718, P < 0.05]. Conclusion:Xiaoer Jinqiao granule combined with interferon α-2b has obvious curative effect on acute herpangina in children because it can improve the humoral and cellular immune function and reduce myocardial damage.

objective To evaluate the therapeutic efficacy of surgical and nonsurgical treatment and the clinical factors affecting the efficacy in traumatic optic neuropathy. Methods To analyse retrospectively the efficacy of recovery of visual acuity in 40 cases of traumatic optic neuropathy after treatment with transnasal endoscopic sphenoethmoidal optic canal decompression (28 cases) and drug therapy (12 cases). Results No significant difference existed between the therapeutic efficacy of surgery and that of drug therapy in patients with the visual acuity of LP～0.02. In surgery group,the therapeutic efficacy of the patients with visual acuity of LP～0.02 was better than that of the patients with no LP.The therapeutic efficacy of patients with duration shorter than seven days before sutgery is better than that of patients with duration longer than seven days. Conclusions The patients with serious traumatic comperssive optic neuropathy should not be treated with decompressive surgery and should not delay to at most seven days after injury.With or without the visual acuity of light perception of the affected eye surgery is usually an important factor affecting the therapeutic efficacy.

Objective To investigate the efficacy and feasibility of extra-peritoneal larparoscopic radical prostatectomy (eLRP) in the treatment of patients with high-risk prostate cancer (HRPC).Methods From February 2009 to December 2013,121 patients,who were diagnosed as HRPC according to the D'Amico definition,were received eLRP.The mean age was 70 years old (range 54 ～ 82 years old).The mean PSA level was 25.45 (range 2.40 ～ 111.31) μg/L and mean Gleason score was 8 (range 6 ～ 10).The classification of clinic stage in this study included 52 cases in cT1-cT2b,58 cases in cT2c,8 cases in cT3a,and 3 cases incT3b,respectively.The perioperative data were collected,including operative time,blood loss,intraoperative complications,urine leakage,lymph leakage,incontinent ability,erectile function and changing of PSA level.Results All the operations were successfully performed.The mean operative time was 165 minutes (range 105 ～341min),the average blood loss was 150 ml(range 50 ～ 1500ml).The intraoperative complications included hemorrhage in 4 cases and intra-operative obturator nerve injury in 3 cases.The mean duration of intestinal function recovery was 35h (range 24 ～72h) The mean interval of catheter indwelling was 9 days (range 7 ～14 days).The anastomotic leakage was found in 12 cases,including 1 day after surgery in 5 cases,2 days after surgery in 3 cases,3 days after surgery in 2 cases,4 day after surgery in 1 case and 5 day after surgery in 1 case.The anastomotic stricture in 3 cases within 2 to 4 months after operation,which the symptom improved after urethral dilation in 2 cases and urethrotomy in 1 case.Deep vein thrombosis was noticed in 1 case 5 days after the procedure.And lymphatic fistula was recorded in 1 case after the operation.Positive surgical margin,seminal vesicle invasion,and positive iliac vessel lymph node were found in 18,21,and 9 patients,respectively.The mean hospitalization duration was 10 days (range 5 ～ 22 d).Of the 107 patients followed-up,Ninety-six patients were continent in 1 year,except other 11 patients.Nerve sparing procedure was performed in 51 patients,and thirty-three of them were potent.The mean PSA level was 0.14 μg/L (range 0 ～8.75 μg/L) six weeks after the surgey.Fourty-eight patients had biochemical recurrence with 5 ～36 months followed-up,mean 18 months.Conclusions Extraperitoneal LRP is an efficacious approach for patients with high-risk prostate cancer.

Mild cognitive impairment is a transitional state between normal aging and dementia, which is the best intervention window to delay cognitive decline.As one of the adjustable risk factors affecting cognitive function, perceived stress significantly increases the risk of cognitive impairment by causing hypothalamic-pituitary-adrenal axis dysfunction and psychological disorders.Therefore, perceived stress management will become a new hot spot in the research and practice of non-drug intervention techniques for cognitive impairment.This paper reviews the current situation of perceived stress in MCI population, the relationship between perceived stress and cognitive function, and the evaluation techniques of MCI individual perceived stress.Further more, this paper summarizes the relevant influencing factors of perceived stress based on stress attribution model, and comments on the action mechanism and practical enlightenment of perceived stress intervention program on cognitive function management, in order to provide theoretical reference for cognitive function management of MCI population.

Objective To investigate the influence of ovarian arterial blood flow index on pregnancy outcomes in patients undergoing in vitro fertilization and embryo transfer (IVF-ET).Methods Totally 136 infertile patients undergoing IVF-ET from February 2014 to April 2016 were divided into pregnant group and non-pregnant group.The monitoring through transvaginal B of two groups for chorionic gonadotropin (HCG) day and ovarian artery resistance index (RI),pulsatility index (PI) and umbilical artery diastolic flow velocity height ratio (S/D) on 2nd day of menstruation (M2) was conducted.The difference of blood flow indexes in two groups was analyzed.Results Compared with those in non-pregnant group,RI,PI and S/D in pregnant group were decreased on M2,and the difference was statistically significant (P ＜ 0.05).RI and PI were also decreased significantly on HCG day,and the difference was statistically significant (P ＜ 0.05),but S/D showed no significant changes (P ＞ 0.05).RI and PI decreased significantly on HCG day in two groups (P ＜ 0.05) when compared with those on M2,but in non-pregnant group,the comparison of S/D on HCG day showed no statistical significance (P ＞ 0.05).Conclusions There is close relationship among RI and PI of ovarian artery and ovarian reserve function.RI and PI are effective indexes to predict outcomes in IVF-ET,and provide scientific basis for the preparation and treatment for IVF-ET.

Objective To preliminarily evaluate the feasibility,therapeutic effect and normal tissue complications of stereotactic γ-ray body radiation therapy for patients with asynchronous bilateral renal cell carcinoma.Methods Nine patients with inoperable asynchronous bilateral renal cell carcinoma with a median time from the resection of the primary focus and discovery of the contralateral focus underwent stereotactic γ-ray body radiotherapy with OUR-QGD stereotactic γ-ray whole body therapeutic planning system.50％ isodose line,as the prescription dose line,was to cover the planning target volume (PTV) and the 70％ isodose line was to cover the gross target volume (GTV).Radiotherapy was delivered,with a single dose of 3-5 Gy per fraction,one fraction per day,5 fractions per week,and totally 10-17 fractions.The PTV edge total dose was 36-51 Gy,and the GTV edge total dose was 60-85 Gy.The patients were followed up for a median time of 24 months to evaluate the local control rate and overall survival rate.Results Of the 9 patients,1 presented complete remission (11.1％) and 4 partial remission (44.5％),with a total effective rate of 55.6％.The 1-,3-,and 5-year local control rates were 64.8％,43.2％,and 43.2％ respectively.The 1-,3-,and 5-year overall survival rates were 66.7％,53.3％,and 35.6％ respectively.Four patients (44.4％) had acute radiation reaction:2 cases with grade l leukocytopenia and 2 cases with grade 1 gastrointestinal reactions.Two patients showed grade 2 late radiation-induced reaction in gastrointestinal system.The Karnofsky score was significantly increased and the renal function was normal after radiotherapy.Conclusions Stereotactic γ-ray body radiation therapy is safe and effective in the treatment of asynchronous bilateral renal cell carcinoma.
