Since the fecal bacteria transplantation (FMT) had been exist for a long time, it attracted more attention in recent years because this therapy could adjust the bacteria disturbance rapidly in clinical settings. Recent studies demonstrated that fecal microbiota transplantation (FMT) has great clinical value in the treatment of Clostridium difficile infection, inflammatory bowel disease, Intractable functional constipation and other diseases. But the FMT is not as perfect as we expect, so we did this article to review the history and terminology of FMT, and summarized the progress in nursing methods of FMT.

Objective To investigate the risk factors of hypogonadism in male type 2 diabetic patients.Methods A total of 213 male patients with type 2 diabetes were enrolled and divided into low testosterone group (n=75) and normal testosterone group (n=138). Blood pressure, blood glucose, blood lipids, serum insulin and sex hormones including total testosterone (TT), sex hormone binding globulin (SHBG), progesterone, prolactin, estradiol, luteinizing hormone (LH), follicle-stimulating hormone (FSH), dehydroepiandrosterone (DHEA) were measured in all patients.The correlations between the metabolic index and sex hormone levels were analyzed.Results Compared with normal testosterone group, body mass index (BMI), fasting insulin (FINS), and homeostasis model assessment insulin resistance (HOMA-IR) levels were significantly increased in low testosterone group(all P<0.05)while LH, FSH, and SHBG levels were significantly decreased(all P<0.05).Pearson correlation analysis showed that TT was negatively correlated with FINS and HOMA-IR(r=-0.142,-0.154, both P<0.05)while positively correlated with LH and FSH (r=0.157, 0.138, both P<0.05).TT level in patients with metabolic syndrome(MS) was significantly decreased (P<0.05).A multiple logistic regression analysis revealed that BMI, MS, HOMA-IR, and LH were significant independent risk factors for hypogonadism.Conclusions Hypogonadism often occurs in male patients with type 2 diabetes,especially in patients with MS.BMI, HOMA-IR, LH, and MS are risk factors for hypogonadism in male type 2 diabetic patients.

Objective:To establish and apply the intervention model of professional attitude for nursing undergraduates in universities of Traditional Chinese Medicine (TCM), and to explore its effect on the professional attitude of the nursing undergraduates.Methods:The study started in August 2018 included two steps. The first step was to develop intervention model of professional attitude for nursing undergraduates in universities of TCM based on the three-stage theory of Kelman ′s attitude formation and with Delphi method. After two rounds of expert consultation, the intervention model of professional attitude for nursing undergraduates in universities of TCM was finally formed, including three intervention stages, a total of 41 intervention measurements. The second step was to use the historical control research method. Grade 2016 nursing undergraduate (the year 2016—2020) in Beijing University of Chinese Medicine was taken as the experimental group ( n=86) and adopted the intervention model. Grade 2012 nursing undergraduate (the year 2012—2016) in the same university was taken as the control group ( n=56) and did not adopted the intervention model during their university study. The two groups were continuously evaluated by "Scale for Nurse ′s Professional Attitude" during their four years in the university. The measurement time was within one week of admission and the 16th week of the second semester of each academic year, with a total of 5 times of measurement. Results:Repeated measurement design showed that the scores of Scale for Nurse′s Professional Attitude of the two groups changed with time. At the end of the first year, the score of the scale in the experimental group was (6.06±0.95) points, higher than (5.41±1.08) points of the control group ( t value was 3.765, P<0.001). There was no difference between the two groups at other time points ( P>0.05). Conclusions:The intervention model of professional attitude for nursing undergraduates in universities of TCM has good operability and can improve the professional attitude of nursing undergraduates in universities of TCM during their freshman year. The intervention model needs to be further adjusted to improve the professional attitude in the subsequent learning stage.

Objective To explore the feasibility and efficacy of endoscopic balloon dilation in treatment of esophageal stenosis caused by operation of congenital esophageal atresia. Methods A retrospective analysis was performed on data of 218 children with type Ⅲ esophageal atresia, who underwent surgery in Zhengzhou Children' s Hospital from January 2009 to December 2017. The occurrence of postoperative complications and efficacy of endoscopic balloon dilation in treatment of esophageal stenosis was analyzed. Results Among the 218 patients with congenital esophageal atresia, 92 were type Ⅲa and 126 were type Ⅲb. Postoperative anastomotic leakage occurred in 46 cases (21. 1％), including 29 (31. 5％) of type Ⅲa and 17 (13. 5％) of type Ⅲb. Postoperative anastomotic stenosis occurred in 53 cases (24. 3％), including 29 ( 31. 5％) of type Ⅲa and 24 ( 19. 0％) of typeⅢb. The incidence of anastomotic leakage and anastomotic stenosis in different types was significantly different (χ2=10. 383, P=0. 001; χ2=4. 497, P=0. 034). The 53 cases of anastomotic stenosis underwent 123 times of endoscopic balloon dilation, with mean time of 3. 5±1. 6, and were finally clinically recovery. No esophagus perforation occurred. Among them, 29 cases of type Ⅲa underwent 73 times with mean of 4. 0±1. 8, and 24 cases of type Ⅲb underwent 50 times with mean of 2. 5±0. 7. The difference between the two types was statistically significant (t=-4. 053, P=0. 027). Conclusion Children with type Ⅲa esophageal atresia has a higher incidence of anastomotic stenosis and leakage, and more times of esophageal dilation. Endoscopic balloon dilation is safe and effective in treatment of esophageal stenosis after surgery for patients with congenital esophageal atresia.

Objective:To explore the value of thyroid radioactive iodine uptake (RAIU) on predicting the residual activity in patients with differentiated thyroid carcinoma (DTC) after administration of 131I. Methods:A total of 178 patients (63 males, 115 females, age: (39.8±11.4) years) with DTC who underwent initial treatment of 131I in Suzhou Science & Technology Town Hospital between August 2018 and April 2019 were enrolled in this retrospective study. RAIU test and thyroid imaging were performed before 131I treatment. Patients were divided into 3 groups according to the thyroid remnant showed by thyroid imaging: no remnant group, a little remnant group, and obvious remnant group. Radiation dose equivalent rates at different time points (immediately/24 h/48 h/72 h after injection of 131I) were measured to estimate the residual activity of 131I after administration. RAIU and residual activity at 72 h among different thyroid remnant groups were compared by one-way analysis of variance. Relationship between RAIU/ 131I therapeutic dose and residual activity at 72 h was analyzed by Pearson correlation analysis. The linear regression equation between RAIU and residual activity at 72 h after treatment was established. Results:The 3 h RAIU in no remnant group ( n=45), a little remnant group ( n=101), and obvious remnant group ( n=32) were (4.77±1.46)%, (5.53±1.70)% and (8.92±3.75)%, respectively ( F=39.35, P<0.01), and the 24 h RAIU was also significantly different among those 3 groups ((1.54±0.88)%, (3.41±2.55)%, (13.52±8.59)%; F=91.52, P<0.01). The residual activity at 72 h in no remnant group, a little remnant group, and obvious remnant group were (81.70±25.61), (108.24±51.58) and (283.07±133.72) MBq, respectively ( F=92.84, P<0.01). There was a significant positive correlation between RAIU and the residual activity at 72 h (3 h: r=0.753, 24 h: r=0.817, both P<0.01). The linear regression equations between RAIU at 3 h and 24 h and the residual activity at 72 h were y=28.88 x-38.42 and y=13.87 x+ 67.01, respectively. When RAIU was higher than 24.01% at 3 h or 15.18% at 24 h, the residual activity at 72 h after treatment was likely to exceed 400 MBq. There was little correlation between 131I therapeutic dose and the residual activity at 72 h after treatment ( r=0.119, P>0.05). Conclusion:RAIU can be used to predict the residual activity at 72 h after treatment in DTC patients who underwent initial 131I treatment.

Objective:To study the effect of total flavonoids of Rhizoma Drynariae on learning and memory impairment mice induced by sodium nitrite. Methods:75 mice were divided into blank group, model group, Kangnaoshuai capsule group, Rhizoma Drynariae total flavonoids group and Rhizoma Drynariae total flavonoids+inhibitor group according to the random number table method, with 15 mice in each group. The Kangnaoshui Capsule group was administered with Kangnaoshui Capsule 585 mg/kg, the Rhizoma Drynariae total flavonoids group was administered with the Rhizoma Drynariae total flavonoids 97.5 mg/kg, the Rhizoma Drynariae total flavonoids group and the inhibitor group were administered with the Rhizoma Drynariae total flavonoids by intragastric administration 97.5 mg/kg, and intraperitoneal injection of 0.072 mg/kg ICI182780 for 21 days, once a day. The model was established on the 22nd day. Except for the blank group, the other mice were injected with sodium nitrite intraperitoneally to replicate the mice model with impaired learning and memory capability. The learning and memory capabilit of mice were detected with water maze method, and the estrogen receptor in hippocampus was detected by immunohistochemistry β (estrogen receptor β, ERβ). The expression of ERβ in hippocampus and the expression of phosphorylated P38 (P-P38) and the protein contents of B-cell lymphoma-2 (Bcl-2), Bcl-2 associated death promoter (Bad) and Caspase-3 in the apoptotic system was detected by Western blot. The kit was used to detect MDA,SOD and NO protein content in hippocampus. Results:The latency of Rhizoma Drynariae total flavonoids group was significantly shorter than the model group, the number of crossing platform and the residence time in the target quadrant were significantly increased ( P<0.01); The expression of ERβ Protein in mice hippocampus (0.371 ± 0.010 vs. 0.124 ± 0.009), Bcl-2 protein (1.146 ± 0.028 vs. 0.726 ± 0.016) and the contents of SOD [(153.657 ± 6.385) U/mg vs. (67.719±5.845) U/mg] increased significantly ( P<0.01); The expression of P-P38/P38 protein (0.412 ± 0.043 vs.0.806 ± 0.069), Bad protein (0.421 ± 0.010 vs.0.633 ± 0.010), Caspase-3 protein (0.923 ± 0.042 vs.1.437 ± 0.033), and the content of MDA [(8.669 ± 0.662) nmol/mg vs. (11.772 ± 1.054) nmol/mg] and NO [(4.259 ± 0.225) nmol/mg vs. (10.805 ± 0.415) nmol/mg] decreased significantly ( P<0.01). In addition, ER blocker can antagonize the above recovery and improvement effects of Rhizoma Drynariae total flavonoids group. Conclusion:Rhizoma Drynariae total flavonoids can regulate memory impairment, inhibit neuronal apoptosis and reduce oxidative stress in sodium nitrite model mice through ER-P38/MAPK signal pathway.
