Objective To investigate nerve fibers distribution in endometrium of adenomyosis and their relationship with dysmenorrhea. Methods Endometrial tissue was sampled from 74 hysterectomy specimens including 32 cases with adenomyosis and 42 cases with uterine fibroids. Two-step Envision immunohistochemical staining was used to detect distribution of nerve fibers in endometrium. Highly specific polyclonal rabbit anti-protein gene product 9.5 (PGP9.5) and monoclonal mouse anti-neurofilament protein (NF) were used to demonstrate both myelinated and unmyelinated nerve fibers in endometrium in women with adenomyosis and uterine fibroids. Results The positive rate of PGP9.5 immunoreactive nerve fibers in the functional layer of endometrium of pain patients were with 64%(14/22) in adenomyosis and 67% (10/15) in uterine fibroids. And their density were 0.6(0-9.4)/mm2 and 0.6(0-6.0)/mm2 without reaching statistical difference (P> 0.05). No expression of NF could be detected in the functional layer of endometrium of adenomyosis and uterine fibroids. There were no PGP9.5 immunoreactive nerve fibers in the functional layer of endometrium in non-pain women with adenomyosis and uterine fibroids. Moreover, No NF immunoreactive nerve fibers in the functional layer of endometrium were shown in non-pain patients with adenomyosis and uterine fibroids. PGP9.5 immunoreactive nerve fibers and the nerve density in the basal layer of endometrium were 64%(14/22), 1.1(0-12.0)/mm2 in pain adenomyosis and 50%(5/10), 0.6(0-3.0)/mm2 in non-pain adenomyosis. NF immunoreactive nerve fibers and the density in the basal layer of endometrium were 23%(5/22),(0-0.6)/mm2 in pain adenomyosis and 20% (2/10),(0-1.0)/mm2 in non-pain adenomyosis. PGP9.5 immunoreactive nerve non-pain fibroids. NF immunoreactive nerve fibers and the nerve density in the basal layer of endometrium were 40%(6/15),0(0-0.4)/mm2 in pain fibroids and 15%(4/27),0(0-1.0)/mm2 in non-pain fibroids. There was no statistical different PGP9.5 and NF immunoreactive nerve fibers distribution in basal layer of endometrium between pain adenomyosis and pain fibroids or between non-pain adenomyosis and non-pain fibroids (all P>0.05). However, PGP9.5 immunoreactive nerve fibers density in basal layer of endometrium was higher in pain adenomyosis and fibroids when compared with non-pain adenomyosis and fibroids(P<0.05). Conclusions PGP9.5 immunoreactive nerve fibers might confer the occurrence of pelvic pain, however, NF immunoreactive nerve fibers may not involved in the pathogenesis of pain.

ObjectiveTo analyze the clinical manifestation of hemolytic disease of the newborn (HDN) due to anti-M and Rhesus system.MethodsClinical information was collected and analyzed for three cases with HDN due to anti-M and 64 with Rhesus hemolytic disease, who were admitted to Department of Neonatology, Beijing Children's Hospital Affiliated to Capital Medical University from February 2011 to January 2015, as well as another 28 cases of HDN due to anti-M with complete information retrieved from literature in Wanfang and China National Knowledge lnfrastructure (CNKI) Database from 1992 to 2014.Chi-square test was performed for statistical analysis.ResultsTwo out of the 64 Rh hemolytic babies gave up therapy due to kernicterus and another two out of the 31 MN hemolytic babies, obtained from literature, died 24 h after birth because of anemia or edema, while the rest survived. Although more babies were the first child of the family in HDN due to anti-M than those of Rh hemolytic disease [26%(8/31) vs 9%(6/64),χ2=4.487, P=0.034], but lower incidence of jaundice [81%(25/31) vs 98%(63/64),χ2=9.686,P=0.002], less proportion of presentation of jaundice within 24 h after birth [29% (9/31) vs 64%(41/64),χ2=10.279,P=0.001] and lower positive rate of direct antiglobulin test [39%(12/31) vs 100%(64/64), Fisher exact test,P=0.000] were shown in HDN due to anti-M. No significant difference was found in the incidences of hyperbilirubinemia [58%(18/31) vs 66%(42/64),χ2=0.513], severe hyperbilirubinemia [23%(7/31) vs 36%(23/64),χ2=1.724], anemia [81%(25/31) vs 89%(57/64),χ2=1.253] and severe anemia [29%(9/31) vs 34%(22/64),χ2=0.271] between HDN due to anti-M and Rh hemolytic babies (allP>0.05).ConclusionsHDN due to anti-M and Rhesus hemolytic disease can cause severe pathological jaundice and/or anemia in newborns. Indirect antiglobulin test should be offered when direct antiglobulin test is negative which is helpful in the diagnosis of HDN due to anti-M.

Objective:Scope review of exercise-related research in patients with inflammatory bowel disease (IBD), while pointing out the limitations of existing research, and providing references for future studies in this area.Methods:We searched PubMed, EMBASE, Web of science, Cochrane databases, China Biology Medicine, Chinese National Knowledge Infrastructure, Wan Fang Data, and Chinese Science Journal Database for studies related to exercise intervention in patients with IBD from January 1974 to July 2020. We extracted data from the included studies. Then we summarized and presented the results.Results:16 articles were finally included, of which 14 were randomized controlled trials and 2 were quasi-experimental studies. Results show that exercise methods can be divided into four categories: aerobic exercise, resistance exercise, flexibility exercise and mixed exercise. The intensity of exercise was mostly low to moderate. The frequency of exercise was mostly 3 times/week, lasting for 30-60 minutes per session. The results showed that exercise had positive effects on physical fitness, bone density, anxiety and depression, quality of life among patients with IBD. However, the effect of exercise on disease activity are diverse.Conclusion:exercise is beneficial to the mental and physical health among this group, but the existing studies have small sample sizes, short exercise intervention period, neglect of individualization in exercise prescription design, low exercise compliance, non-uniformity of exercise effect evaluation indicators.

Both diabetes mellitus and liver cirrhosis have high incidence rate and mortality rate around the world, and in recent ten years, scholars in China and globally have conducted many studies on the association between diabetes mellitus and liver cirrhosis. This article systematically reviews the advances in the basic and clinical research on the influence of diabetes mellitus on liver cirrhosis and its complications and summarizes possible mechanisms. The results show that diabetes mellitus can accelerate the process of liver fibrosis, increase the risk of complications and progression to liver cancer in patients with liver cirrhosis, and reduce their survival rate.

This article reviews the research advances in the pathogenesis of HD, in order to provide a reference for the diagnosis and treatment of HD by clinicians.

Objective To investigate the impact of salpingectomy with preservation of fallopian tube mesentery on ovarian reserve function. Methods A total of 281 patients with tubal disease who were admitted from January 2020 to March 2021 were collected as research objects. According to the different treatment methods, they were divided into traditional bilateral resection group (n=53, conventional bilateral salpingectomy), traditional unilateral resection group (n=56, conventional unilateral salpingectomy), preservation of bilateral resection group (n=60, bilateral salpingectomy with preservation of fallopian tube mesentery), preservation of unilateral resection group (n=54, unilateral salpingectomy with preservation of fallopian tube mesentery), and control group[n=58, patients with in vitro fertilization-embryo transfer (IVF-ET) but no history of salpingectomy]. The operation time, intraoperative blood loss, and postoperative exhaust time were compared among the groups. Two months after the operation, IVF-ET was performed, and the number of follicles and oocytes, pregnancy rate, and fertilization rate were detected. The levels of anti-mullerian hormone (AMH), follicle-stimulating hormone (FSH), estradiol (E₂), and luteinizing hormone (LH) in peripheral blood were detected after IVF-ET. Follow-up was conducted until March 2023, and pregnancy success rates were recorded for the five groups. Results There were no significant differences in perioperative operation time, intraoperative blood loss, and postoperative exhaust time among traditional bilateral resection group, traditional unilateral resection group, preservation of bilateral resection group, preservation of unilateral resection group (P>0.05). After IVF-ET, there were significant differences in AMH, FSH, E₂, and LH levels among the five groups (P < 0.05). The levels of AMH and E₂ in a rising sequence were traditional bilateral resection group, traditional unilateral resection group, preservation of bilateral resection group, preservation of unilateral resection group and control group, while the levels of FSH and LH in descending sequencing were traditional bilateral resection group, traditional unilateral resection group, preservation of bilateral resection group, preservation of unilateral resection group and control group. Follow-up was conducted until March 2023, and the pregnancy success rates after IVF-ET were 45.28%, 50.00%, 53.33%, 59.26%, and 58.62% in the traditional bilateral resection group, traditional unilateral resection group, preservation of bilateral resection group, preservation of unilateral resection group, and control group, respectively. There was no significant difference in pregnancy success rate after IVF-ET among the five groups (χ²=3.044, P=0.551). Conclusion Compared with traditional salpingectomy, salpingectomy with preservation of fallopian tube mesentery has less impact on ovarian reserve function.

Objective:To observe the effect of self-designed Buqi Huoxue Decoction on the rehabilitation of patients with stroke sequelae and qi deficiency and blood stasis syndrome.Methods:A total of 116 patients with stroke sequelae treated from October 2019 to October 2020 were selected and divided into observation group and the control group by randomized digital tables, 58 patients in each group. The control group was given the conventional treatment, and the observation group combined self-designed Buqi Huoxue Decoction and conventional treatment. Both groups were treated for 3 months. The soluble vascular cell adhesion molecule-1 (sVCAM-1), nito-oxide (NO), endothelin (ET-1), endothelial-derived hyperpolarization factor (EDHF), insulin-like growth factor (IGF-II), interleukin-1β (IL-1β), interleukin-6 (IL-6) levels were detected by ELISA. The National Institutes of Health Stroke Scale (NIHSS) was used to evaluate the degree of neurological deficit, motor function was evaluated by the Fugl-Meyer motor function scale (FMA), patients' daily living ability was assessed by daily living ability assessment table (ADL), the QLQ-C30 was used to evaluate the QoL of patients. The TCM syndrome scores were evaluated. The clinical response was compared between the two groups.Results:The total response rate was 94.8%(55/58) in the observation group and 81.0%(47/58) in the control group. There was significant difference between the two groups ( χ2=3.98, P=0.046). After treatment, the scores of TCM syndrome and NIHSS of pruritus in the observation group were significantly lower than those in the control group ( t values were 5.61, 5.21, respectively, all Ps<0.01). After treatment, the scores of FMA, ADL QLQ-C30 of pruritus in the observation group were significantly higher than those in the control group ( t values were 3.61, 3.13, 9.38, respectively, all Ps<0.01). After treatment, the NO[(87.61±19.18) μmol/L vs. (77.93±17.26) μmol/L, t=2.81], EDHF [(21.14±6.14) μmol/L vs. (16.61±4.52) μmol/L, t=4.45] levels in the observation group were significantly higher than those in the control group ( P<0.01). After treatment, the sVCAM-1[(309.58±30.11) μg/L vs. (354.16±33.04) μg/L, t=7.46], ET-1 [(50.07±18.23)ng/L vs. (66.31±17.89)ng/L, t=4.76] levels in the observation group were significantly lower than those in the control group ( P<0.01). After treatment, IL-1β, IGF-Ⅱ, IL-6 levels in the observation group were significantly lower than those in the control group ( t values were 4.66, 8.14 7.43, respectively, all Ps<0.01). Conclusion:The treatment of self-designed Buqi Huoxue Decoction can improve the vascular endothelial function, inhibit the inflammation, reduce the nerve function damage, improve the limb movement function, daily life ability, quality of life and the clinical symptoms.
