Objective:To discuss the oncologic safety, aesthetic outcome, and upper extremity function of single-port insufflation endoscopic nipple-sparing mastectomy (SIE-NSM) in the treatment of early breast cancer.Methods:From January 2014 to August 2019, a total of 80 patients with stage Ⅰ and Ⅱ breast cancer underwent SIE-NSM, at Beijing Friendship Hospital, Capital Medical University were retrospectively analyzed and followed up. Estimated the oncologic safety, aesthetic outcome, and upper extremity function.Results:SIE-NSM was performed successfully on all 80 patients.There was no serious complication after surgery.The follow-up time was 16-82 months and the median follow-up time was 42 months. Local recurrence occurred in two patients, and there was no distant metastases. Four (5%) patients developed grade 1-3 nipple-areola complex ischemia. There were no cases of subcutaneous effusion.The satisfaction with breasts, chest well-being, psychosocial well-being, and sexual well-being scores were confirmed to be highly rated by Breast-Q scale. Upper extremity function score confirmed that good upper limb function was preserved after surgery. The mean length of incision was (3.6±0.8) cm, and the blood loss was (24.7±19.3) mL.Conclusions:SIE-NSM can achieve a higher cosmetic score and a better recovery of upper limb function on the premise of ensuring the safety of the tumor.This novel method is an appropriate surgical option for patients with early breast cancer.

Objective: We primarily aimed to investigate the attention network function among parents of children with autism spectrum disorder (ASD) using the Attention Network Test (ANT). The secondary objective was to observe whether the three attention networks of all participants were related to each other. Methods: We included 28 parents of children with ASD and 28 well-matched parents of typically developing children. All participants underwent the neuropsychological assessment and ANT test. The three distinct attention networks, including alerting, orienting, and executive control, were also measured. Results: Compared with controls, parents of children with ASD showed less-efficient alerting and executive control network (all p<0.05), but not orienting network (p=0.74). No significant correlation was found between the alerting, orienting, and executive control network for either group. Conclusion Our findings showed that parents of children with ASD had deficits in alerting and executive control attention functions. The deficits are indications of a broad autism phenotype.

Objective To observe the dynamic changes of ghrelin of spleen-qi-deficiency rats and the intervention effects ofSijunzi Decoction.Methods Experimental rats were randomly divided into normal control group, model group andSijunzi Decoction group. Except for normal control group, spleen-qi-deficiency model was copied through the two-factor methods of breaking qi by bitter cold and swimming exhausted. Meanwhile,Sijunzi Decoction group was given 20 g/(kg?d)Sijunzi Decoction intervention. The activities of GAS, MTL, SS and VIP at different time points (14, 21, 28 d) in intestine and serum were detected by ELISA and RIA. At the same time the intervention effect of Sijunzi Decoction was studied.Results Compared with normal control group, GAS and MTL in intestine and serum of model rats decreased, while SS and VIP increased (P<0.05,P<0.01). Compared with model group, GAS and MTL in intestine and serum of rats in theSijunzi Decoction group increased, while SS and VIP decreased (P<0.05,P<0.01).Conclusion Ghrelin in intestine and serum of spleen-qi-deficiency rats shows dynamic coincidental changes.Sijunzi Decoction can treat spleen qi deficiency by regulating the activities of rat ghrelin.

Objective To establish an ideal modeling method for diarrhea predominant irritable bowel syndrome(IBS-D)with anxiely and depression in rats,and to provide a basis for the clinical study of IBS-D.Methods 60 rats were used in this study.(1)At first,20 rats were randomly divided into blank,3%acetic acid enema,4%acetic acid enema,and 5%acetic acid enema groups.After the modeling and observation period,the diarrhea status and the degree of colon injury caused by different modeling concentrations were observed by diarrhea related index and colon histopathology.(2)After the optimal modeling concentration was assessed,40 rats were randomly divided into control(a),acetic acid enema(b),acetic acid+binding(c),and acetic acid+binding+tail clip(d)groups and correspondingly treated for 8 days.After the treatments,the general condition,diarrhea-related index,open field test(OFT)score,and colonic histopathology of rats were evaluated.Results(1)Compared with the blank group,the fecal trait score of 4%acetic acid enema group was increased on days 1 to 3 after intervention(P＜0.001),and gradually decreased on days 4 to 7 after intervention.After 1 week,there was no significant difference between the fecal trait score and that of the blank group(P＞0.05).Body weight was lower(P＜0.01),fecal water content was higher(P＜0.001).Compared with blank group,body weight of the 5%acetic acid enema group was decreased(P＜0.001),the fecal trait score and diarrhea index were increased(P＜0.01).No significant difference was found between 3%acetic acid enema and blank groups.The pathological colon tissue showed that,compared with the blank group,the mucosal structure of the 4%acetic acid enema group was complete with a small amount of inflammatory cell infiltration,and the pathological tissue score showed no significant difference(P＞0.05),whereas the 5%acetic acid enema had a medium to large amount of inflammatory cell infiltration,and the pathological tissue score was increased(P＜0.01).(2)Compared with group a,group b had lower body weight(P＜0.001),and higher fecal trait score,fecal water content and diarrhea index(P＜0.01).Compared with a and b groups,the body weight of c and d groups was lower(P＜0.001),the fecal traits score,fecal water content,and diarrhea index were increased(P＜0.01),and the colon running time was decreased(P＜0.01).Compared with group c,Fecal water content in group D was higher(P＜0.001).In the OFT score,compared with a and b groups,the OFT distance,standing times,and upright times in c and d groups were lower(P＜0.05).Compared with c,the OFT distance,standing times,and upright times in d group were lower(P＜0.05).The pathological tissue of colon showed that the mucosal structure of the four groups was complete,and there were different degrees of inflammatory cell infiltration.The pathological tissue scores of groups c and d were higher than those of groups a and b(P＜0.05).Conclusions The 4%acetic acid concentration is appropriate for IBS-D modeling.After superposition and binding,the IBS-D diarrhea and internal hypersensitivity characteristic state can be better simulated.After superposition of a tail clip,the IBS-D model of liver stagnation and spleen deficiency can be established successfully.

Objective To investigate the effects of Echinococcus multilocularis on the phenotypic transformations of glucose metabolism, polarization types and inflammatory responses in macrophages, so as to provide insights into elucidation of echinococcosis pathogenesis. Methods Bone marrow cells were isolated from C57BL/6J mice at ages of 6 to 8 weeks, and induced into bone marrow-derived macrophages (BMDMs) with mouse macrophage colony-stimulating factor (M-CSF), which served as controls (BMDMs-M0). BMDMs-M0 induced M2 macrophages by interleukin-4 for 24 hours served as the IL-4 induction group, and BMDMs-M0 co-cultured with 2.4 ng/mL E. multilocularis cystic fluid (CF) served as the BMDM-CF co-culture group, while BMDMs-M0 co-cultured with E. multilocularis protoscolex (PSC) at a ratio of 500:1 served as the BMDM-PSC co-culture group. The types of polarization of BMDMs co-cultured with E. multilocularis CF and PSC were analyzed using flow cytometry, and the expression of macrophage markers, inflammatory factors, and glucose metabolism-related enzymes was quantified using fluorescent quantitative real-time PCR (qPCR) and Western blotting assays. Results There were significant differences among the four groups in terms of Arginase-1 (Arg1) (F = 1 457.00, P < 0.000 1), macrophages-derived C-C motif chemokine 22 (Ccl22) (F = 22 203.00, P < 0.000 1), resistin-like α (Retnla) (F = 151.90, P < 0.000 1), inducible nitric oxide synthase (iNOS) (F = 107.80, P < 0.001), hexokinase (HK) (F = 9 389.00, P < 0.000 1), pyruvate kinase (PK) (F = 641.40, P < 0.001), phosphofructokinase 1 (PFK1) (F = 43.97, P < 0.01), glucokinase (GK) (F = 432.50, P < 0.000 1), pyruvate dehydrogenase kinases1 (PDK1) (F = 737.30, P < 0.000 1), lactic dehydrogenase (LDH) (F = 3 632.00, P < 0.000 1), glucose transporter 1 (GLUT1) (F = 532.40, P < 0.000 1), glyceraldehyde-3-phosphate dehydrogenase (GAPDH) (F = 460.00, P < 0.000 1), citrate synthase (CS) (F = 5 642.00, P < 0.01), glycogen synthase1 (GYS1) (F = 273.30, P < 0.000 1), IL-6 (F = 1 823.00, P < 0.000 1), IL-10 (F = 291.70, P < 0.000 1), IL-1β (F = 986.60, P < 0.000 1), and tumor necrosis factor (TNF)-α (F = 334.80, P < 0.000 1) and transforming growth factor (TGF)-β mRNA expression (F = 163.30, P < 0.001). The proportion of M2 macrophages was significantly higher than that of M1 macrophages in the BMDM-PSC co-culture group [(22.87% ±1.48%) vs. (1.70% ±0.17%); t = 24.61, P < 0.001], and the proportion of M2 macrophages was significantly higher than that of M1 macrophages in the BMDM-CF co-culture group [(20.07% ±0.64%) vs. (1.93% ±0.25%); t = 45.73, P < 0.001]. The mRNA expression of M2 macrophages markers Arg1, Ccl22 and Retnla was significantly higher in the BMDM-CF and BMDM-PSC co-culture groups than in the control group (all P values < 0.01), and no significant difference was seen in the mRNA expression of the M1 macrophage marker iNOS among the three groups (P > 0.05), while qPCR assay quantified higher mRNA expression of key glycolytic enzymes HK, PK and PFK, as well as inflammatory factors IL-10, IL-1β, TNF-α and TGF-β in the BMDM-CF and BMDM-PSC co-culture groups than in the control group (all P values < 0.01). Western blotting assay determined higher HK, PK and PFK protein expression in the BMDM-PSC co-culture group than in the control group (all P values < 0.05), and qPCR quantified higher GLUT1, GAPDH and IL-6 mRNA expression in the BMDM-CF co-culture group than in the control group (all P values < 0.05), while higher HK, PK and PFK protein and mRNA expression (all P values < 0.01), as well as lower IL-6 and TNF-α and higher TGF-β mRNA expression (both P values < 0.05) was detected in the IL-4 induction group than in the control group. Glycolytic stress test showed no significant difference in the extracellular acidification rate (ECAR) of mouse BMDM among the control group, IL-4 induction group and BMDM-PSC co-culture group (F = 124.4, P < 0.05), and a higher ECAR was seen in the BMDM-PSC co-culture group and a lower ECAR was found in the IL-4 induction group than in the control group (both P values < 0.05). Conclusions Treatment of E. multilocularis CF or PSC mainly causes polarization of BMDM into M2 macrophages, and phenotypic transformation of glucose metabolism into high-energy and high-glycolytic metabolism, and affects inflammatory responses in BMDM.

ObjectiveTo investigate the possible mechanism of Hewei Anshen Formula （和胃安神方） in the treatment of insomnia. MethodsSixty male SD rats were randomly divided into the normal group， the model group， the eszopiclone group and the low-， medium- and high-dose Hewei Anshen Formula groups. The insomnia model was constructed by intraperitoneal injection of p-chlorophenylalanine （PCPA） for 2 days in all groups except the normal group. After successful modelling， the eszopiclone group was given 0.33 mg/（kg·d） eszopiclone aqueous solution by gavage， the low-， medium- and high-dose Hewei Anshen Formula groups were given 10 ml/kg of Hewei Anshen Formula with a concentration of 1， 2 and 4 g/ml， respectively， and the rats in the normal group and the model group were given 10 ml/kg of saline by gavage， once a day for 7 consecutive days. The general condition of the rats was observed during the experiment， and the body mass of the rats was measured every day after medication administration. The following day after the last medication administration， pentobarbital sodium co-test was used to observe the sleep condition， and the sleep latency and sleep duration were recorded； immunohistochemistry and Western blot were used to detect the expression of hypothalamic clock rhythm regulating protein （CLOCK） and brain and muscle aromatic hydrocarbon receptor nuclear transporter-like protein 1 （BMAL1） in the rats. ResultsThe body mass of rats in the model group was lower than that of rats in the normal group at all time points （P＜0.01）； compared with the same time in the eszopiclone group， the body mass of rats in the low-dose Hewei Anshen Formula group was elevated on the 5th， 6th and 7th days of medication administration （P＜0.05）. Compared with the normal group， the sleep duration of rats in the model group was shortened （P＜0.01）； compared with the model group， the sleep duration of rats in each dosage group increased （P＜0.01）， and the difference between the high-dose Hewei Anshen Formula group and the eszopiclone group showed no statistically significant （P＞0.05）， while the sleep duration of the low- and medium-dose Hewei Anshen Formula groups were shorterned than the eszopiclone group （P＜0.01）. The difference in sleep latency showed no statistically significant among each group （P＞0.05）. The results of both immunohistochemistry and Western blotting showed that the expression of CLOCK and BMAL1 in the hypothalamus of rats in the model group was significantly reduced compared with that in the normal group （P＜0.01）； the expression of CLOCK and BMAL1 in the hypothalamus of rats in the low- and high-dose Hewei Anshen Formula groups increased than that in the model group （P＜0.05 or P＜0.01）. ConclusionHewei Anshen Formula can improve insomnia in model rats， and its mechanism of action may be related to the up-regulation of the expression of the hypothalamic biological clock genes CLOCK and BMAL1 protein.

ObjectiveTo observe the clinical effectiveness and safety of Hewei Anshen Formula （和胃安神方） for stress-induced insomnia. MethodsA total of 104 male patients with stress-induced insomnia were randomly divided into a treatment group and a control group， with 52 cases in each group. The treatment group was given Hewei Anshen Formula once a day， while the control group was given zolpidem tartrate tablets 10 mg per time and once a day， and both groups were treated for 4 weeks. The Pittsburgh Sleep Quality Index （PSQI） was applied to evaluate sleep quality before and after treatment， Ford Insomnia Response to Stress Test （FIRST） was used to evaluate insomnia susceptibility， MOS 36-tem Short Form Health Survey （SF-36） ［which includes the domains of Physical Component Summary （PCS） and Mental Health Component Summary （MCS）， with the PCS including the General Health （GH）， Physical Functioning （PF）， Role Physical （RP）， and Body Pain （BP）， and the MCS including Role Emotional （RE）， Social Functioning （SF）， Vitality （VT）， Mental Health （MH）］ was used to evaluate the quality of life， and Fatigue Scale 14 （FS-14） ［including somatic fatigue and brain fatigue scores］ to evaluate the degree of fatigue， and the traditional Chinese medicine （TCM） syndrome scores using a self-developed TCM syndrome survey for insomnia. Clinical effectiveness and TCM syndrome improvement were determined after treatment. The occurrence of adverse events and adverse reactions was recorded during treatment. ResultsThe total effective rate of clinical effectiveness was 90.38% （41/52） in the treatment group and 80.77% （42/52） in the control group， and the difference between the two groups was not statistically significant （P＞0.05）. The total effective rate of TCM syndrome effectiveness in the treatment group was 80.77% （42/52）， which was higher than 44.23% （23/52） in the control group， and the difference was statistically significant （P＜0.01）. The TCM syndrome score， FIRST score， brain fatigue scores， brain fatigue score and total score of FS-14 score all reduced after treatment in both groups， and all scores were lower in the treatment group than those in the control group after treatment （P＜0.05）. All transformed scores of SF-36 scores were higher in both groups after treatment than before treatment in this group， and they were better than the control group in the four dimensions of PF， RP， VT， and MH （P＜0.05）. There were no adverse events and adverse reactions in the two groups. ConclusionHewei Anshen Formula can improve patients' sleep quality， effectively relieve clinical symptoms such as fatigue and pain， alleviate TCM syndromes， enhance the quality of life， reduce the susceptibility to insomnia， and shows good safety.
