Objective To investigate the effect of Niaoduqing Particles on the microinflammatory state in patients with maintenance hemodialysis. Methods Totally 240 patients with hemodialysis for more than 6 months were randomly divided into conventional hemodialysis group, Chinese medicine group (treated with Niaoduqing Particles) and western medicine group (treated with Vitamin E), 80 cases in each group, with 30 healthy people as control group. The levels of hs-CRP, IL-6 and HCY were detected before and after 1, 3, 6 months of treatment. Results Before treatment, the levels of inflammatory factors in hemodialysis patients were higher than control group. And after 3 months of treatment, the levels of hs-CRP, IL-6 and HCY of Chinese medicine group were decreased. And after 6 months of treatment, the levels of inflammatory factors were decreased obviously compared with pretherapy (P<0.01), and the difference with the conventional hemodialysis group was significant (P<0.01). Compared with pretherapy, the changes of inflammatory factors of western medicine group were statistically insignificant. Conclusion Niaoduqing Particles can significantly improve the microinflammatory state in maintenance hemodialysis patients, and the effect is superior to Vitamin E.

Objective To observe the dilated cardiomyopathy ( DCM ) in non-Keshan disease areas in Shandong Province and assess scientifically the effectiveness of prevention and control measures on Keshan disease (KSD). Methods According to the scheme of DCM condition survey of our country in non-Keshan disease areas, seven representative counties(cities, areas) were chosen by their similarities in natural environment, production and life style to KSD areas; one or two townships ( towns ) were chosen in each county ( city , area ); one village was selected as a survey point in each township ( town ) . In each survey point , about four hundred and twenty natural populations were checked by asking detailed history, physical examination, and electrocardiography (ECG) tracings, and suspicious people were taken chest X-ray examination and cardiac ultrasound(UCG). The samples of inside and outside environmental were collected in partial residents and the selenium contents were detected by 2,3-diaminonaphthalene fluorometric method. At the same time the income, food of inhabitant and other basic information were collected. Results ① In 13 survey villages, sixty-four hundred and sixty-three residents were surveyed and 2 DCM cases and 111 similar potential KSD cases were detected, the detection rate was 1.75%(113/6 463). ② Sixty-four hundred and sixty-three residents were traced by ECG and the incidence of abnormal ECG was 20.4%(1 318/6 463), and sinus bradycardia, T-wave changes, sinus tachycardia, ST-T changes, occasional ventricular beating earlier, complete right bundle branch block, left anterior branch block, room premature beat, left ventricular high voltage, auriculo-ventricular block, et al were common. ③Samples of hair(260), wheat(260), corn (240) and soil (104) were collected, and the selenium contents were (0.353 ± 0.082), (0.035 ± 0.009), (0.024 ± 0.008) and (0.164 ± 0.019)mg/kg, respectively. Annual per capita income of each survey point was 2 500-8 670 yuan, and the residents’ main staple food was flour. Conclusion The results of DCM condition in non-Keshan disease areas of Shandong Province are stable and have provided a scientific basis for drawing up the national standard of eliminating KSD.

Objective To investigate the characteristics of chronic Keshan disease (CKD) and ischemic cardiomyopathy ( ICM ) and provide a basis for differential diagnosis . Methods Forty-two cases of CKD were randomly sampled from 6 Keshan disease districts in Sishui, Zoucheng, Juxian, Wulian, Yishui and Qingzhou Counties of Shandong Province, as CKD group. Thirty-one cases of ICM were selected from Qianfushan Hospital as ICM group. Echocardiography was used to analyze the cardiac morphology , hemodynamic and function. Results Left atrial internal diameter(LA), left ventricular(LV), end-diastolic internal diameter(LVd), right ventricular diameter(RV) and right atrial transverse diameter(RAtd) of the CKD group[(45.14 ± 6.93),(68.48 ± 6.24),(28.90 ± 3.14),(52.79 ± 6.62)mm] were higher than those of ICM group[(40.68 ± 5.12),(60.55 ± 4.07),(24.35 ± 2.12), (47.68 ± 8.53)mm , t = 3.03, 6.55, 7.38, 2.88, all P < 0.01]. In CKD group, several atrioventricular carities were enlarged, and the ventricular wall tended to become thin. In ICM group, left atrioventricular cavities were enlarged, and the apex of LV was thin spherical. The LV ejection fraction(LVEF) and fractional shortening of LV (LVFS) of the CKD group [(40.50 ± 10.68)%, (22.81 ± 6.24)%] were lower than those of the ICM group [(54.61 ± 6.58)%, (30.71 ± 4.29)%, t = - 6.957, - 5.976, all P < 0.01]. Diffuse hypokinetic motion of LV reduced in 85.7%(36/42) of CKD patients, and 83.9%(26/31) of ICM patients had segmental LV dyskinesia. Slight regurgitation of single valve was common in ICM group , but several regurgitation of multiple valves were more common in CKD group. Conclusion Echocardiography is a valuable noninvasive technology for differentiating CKD and ICM.

Objective To study the effects of electroacupuncture (EA) on the elderly's postoperation cognitive dysfunction (POCD) after general anesthesia.Methods Patients who need to have surgical operation done for lumbar spinal stenosis were randomly divided into an observation group (electroacupuncture and routine intravenous anesthesia) and a control group (only routine intravenous anesthesia),and EA was administered to those in the electroacupuncture group for 30 minutes at an interval of 10 minutes,beginning at 30 minutes prior to routine intravenous anesthesia and lasted till the end of the surgery.The differences regarding intraoperative propofol and remifentanil dosage,cognitive function,the levels of serum interleukin-6(IL-6),interleukin-10 (IL-10) and S100-β were compared.Results The intraoperative propofol and remifentanil dosages in observation group were (6.54 ± 3.27) μg/(kg· h) and (3.67 ± 2.53) mg/(kg· h),respectively,while those in control group were (9.70 ± 4.82) μg/kg and (5.62 ± 1.73) mg/kg.The intraoperative propofol and remifentanil dosages in observation group were significantly lower than those in control group (P ＜ 0.05).At 72 hours post-operation the incidence of POCD in observation group was significantly lower than that in control group (1 case,2.5％ versus 8 cases,20％),while the MMSE score was higher in observation group than that in control group (25.7 ± 1.9 versus 23.2 ± 2.1).The post-operation level of serum IL-6,IL-10 and S100-β in observation group were significantly lower than that in control group (P ＜ 0.05).Conclusion Electroacupuncture could significantly improve the elderly's postoperation cognitive dysfunction after general anesthesia.It could inhibit the excessive expressions of IL-6,IL-10 and S100-β,alleviate the brain damage and reduce the incidence of POCD.

Objective:To explore the predictors of recovery of normal left ventricular ejection fraction (LVEF) in patients with chronic Keshan disease (CKD) after standard anti-heart failure treatment.Methods:From June 2013 to October 2017, CKD patients were selected as the research subjects in 8 Keshan disease counties (cities) in Shandong Province. Demographic data and clinical indicators related to the recovery of normal LVEF were collected at the initial diagnosis, and the patients were given standard anti-heart failure treatment. Follow-up was carried out until October 2019 or until all-cause death. Patients were divided into recovery group and non-recovery group according to whether LVEF returned to normal (LVEF≥50% was normal) by group design, and multi-factor logistic regression was used to analyze the predictors of recovery of normal LVEF.Results:A total of 98 CKD patients were included in this study, their average age was (47.51 ± 12.84) years old; body mass index (BMI) was (23.18 ± 4.92) kg/m 2; LVEF was (39.54 ± 8.26)%; male accounted for 65.31% (64/98); the New York Heart Association (NYHA) heart function grade Ⅱ and grade Ⅲ accounted for 46.94% (46/98) and 53.06% (52/98), respectively. The median follow-up time was 26 months, the LVEF of 28 patients (28.57%) returned to normal, and the LVEF increased from (43.27 ± 7.85)% of the baseline to (58.74 ± 6.07)%, the difference was statistically significant ( t=8.25, P < 0.01); LVEF did not return to normal in 70 patients (71.43%), and the LVEF increased from (37.84 ± 6.93)% of the baseline to (42.94 ± 7.31)%, the difference was statistically significant ( t=4.24, P < 0.01). The median recovery time of 28 patients with normal LVEF recovery was 14 months, of which 4 patients (14.29%), 6 patients (21.43%) and 15 patients (53.57%) recovered at follow-up of 6, 12 and 18 months, respectively, and 27 patients (96.43%) recovered within 3 years. The results of multivariate logistic regression analysis showed that disease course [odds ratio ( OR)=0.81, 95% confidence interval ( CI): 0.70-0.95, P < 0.05], electrocardiogram QRS wave duration ( OR=0.88, 95% CI: 0.79-0.98, P < 0.05), LVEF ( OR=1.26, 95% CI: 1.13-1.42, P < 0.01), and left ventricular end-diastolic diameter (LVEDD, OR=0.79, 95% CI: 0.66-0.90, P < 0.01) were independent predictors of recovery of normal LVEF. Conclusions:LVEF can return to normal after anti-heart failure treatment in some CKD patients. Patients with shorter disease course, shorter electrocardiogram QRS wave duration, higher baseline LVEF and lower LVEDD are more likely to recover from LVEF.

Objective:To assess the utility of contrast-enhanced ultrasound (CEUS) targeted biopsy (TB) for clinically significant prostate cancer (PCa) detection.Methods:A total of 983 consecutive patients scheduled for prostate biopsy from October 2015 to March 2019 in Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine were enrolled in this retrospective study. All patients had suspicious lesions on CEUS, defined as increased focal contrast enhancement, rapid contrast enhancement and low enhancement lesions with ill-defined borders. Suspicious lesions on CEUS were sampled in addition with standard 12-core systematic biopsy(SB). Clinically significant PCa was defined using Epstein criteria. The clinically significant PCa detection rate by CEUS-TB and combined biopsy was evaluated in comparison with SB.Results:In 502 of the 983 patients, the diagnosis of PCa was histologically confirmed, including 445 patients with clinically significant PCa and 57 patients with clinically insignificant PCa. The clinically significant PCa by CEUS-TB and combined biopsy were 41.9% (412/983) and 45.3% (445/983) respectively, which was significantly higher than SB (36.8%, 362/983)(all P<0.001). CEUS-TB resulted in additional 83 cases of clinically significant PCa, including 61 patients missed by SB and 22 patients under-graded by SB. Conclusions:CEUS is helpful in the detection of PCa lesions. Combined CEUS-TB and SB can improve the clinically significant PCa detection rate.

OBJECTIVE: To explore the methods for identification of sibling brothers with Y-STR locus mutation by detection of genetic markers on autosome and Y-biallelic. METHODS: Goldeneye 20A and 18NC kit were used to genotyped the 35 STRs on autosome from two men. PowerPlex Y kit and Yfiler kit were used to genotyped the 16 STRs on Y chromosome full sibling index was calculated by ITO method. Twenty Y-biallelic markers were genotyped by fragment length discrepant allele specific PCR or general PCR. RESULTS: Relationship of sibling brothers was found to have mutation of 2 loci on 16 Y-STR and the identical genetype of 20 Y-biallelic markers as well as a cumulative full sibling index of 4.3149 x 10(6) from 35 STRs on autosome. CONCLUSION In identification of paternal linage of Y-STR mutation, more genetic information can be acquired by detection of Y-biallelic markers including SNP and InDel.
