OBJECTIVETo analyze the effects of acupuncture on the level of atrial natriuretic peptide (ANP), C-type natriuretic peptide (CNP) in adrenal gland and the content of corticosterone (CORT) in plasma in rats withchronic emotional stress anxiety, and to explore the partial action mechanism of acupuncture on anxiety disorder.
METHODSThirty-two healthy Sprague-Dawley (SD) rats, after 7 days of feeding and domestication, were randomly divided into a blank group (10 rats), a model group (11 rats) and an acupuncture group (11 rats). The rats inthe model group and acupuncture group were treated with unpredictable chronic emotional stress (CES) method toestablish the model of anxiety. Rats in the acupuncture group were treated with acupuncture at "Neiguan" (PC 6)and "Shenmen" (HT 7), once every other day, 30 minutes each time. The model establishment and treatment lasted 15 days. Rats in the blank group were treated with identical immobilization but no treatment was given. Theelevated plus maze was used to test the behavioral changes of rats with anxiety; the level of CORT in plasma wasdetected by ELISA, and the expression level of CNP and ANP in adrenal cortex and medulla was detected by immunohistochemical method.
RESULTS(1) The percentage of open-arms time in total time (OT%) in elevated plus maze in the model group was significantly lower than that in the blank group (P<0. 05); the OT% in the acupuncture group was significantly higher than that in the model group (P<0.01). (2) The content of CORT in plasma in the model group was higher than that in the blank group (P<0. 05), while that in the acupuncture group was significantly lower than that in the model group (P<0. 05). (3) The expression of ANP in adrenal medulla and cortex in the model group was lower than that in the blank group (P<0. 01), while the expression of CNP in adrenal medulla and cortex in the model group was higher than that in the blank group (P<0. 01).
CONCLUSIONThe effects of acupuncture against anxiety are likely to be related to the regulation on the expression of ANP and CNP in adrenal medulla, affecting the release of CORT and inhibition on the activity !f hypothalamic-pituitary-adrenal axis (HPA axis).

Heart rate variability (HRV) is a reliable, innocuous and sensitive new index to measure cardiac autonomic nervous function. Anxiety disorder is often accompanied by autonomic nerve dysfunction and its main sign is abnormal HRV. Acupuncture can affect HRV indices, correct abnormal HRV and improve cardiac autonomic nerve dysfunction to relieve anxiety. This article sorts out and analyzes recent years’ studies on abnormal HRV in anxiety disorder, the effect of acupuncture on HRV and acupuncture regulation of abnormal HRV in anxiety disorder to provide a therapeutic basis for clinical acupuncture intervention in abnormal HRV in anxiety disorder.

Objective:To explore in state of Chlamydia trachomatis persistent infection,the STAT3-TLR2 axis may be activated and mediating abnormal secretion of inflammatory cytokines.Methods: We established acute infection and IFN-γinduced persistent infection model of Ct in HeLa cell.Gene transcription, cytokine secretion and protein expression were detected by using qRT-PCR, ELISA and Western blot respectively in STAT3-TLR2 signaling axis in each Ct infection model.Results: Persistent Ct infections upregulated the transcription of TLR2,significantly increased both the secretion of inflammatory cytokine IL-1αand the expression of STAT3 and TLR2,moreover,enhanced the activation of STAT3 simultaneously.Conclusion: In the Ct persistent infection induced by IFN-γ,the STAT3-TLR2 signaling axis activated significantly in HeLa cell.

Anxiety disorder is one of the most common mental disorders and seriously impairs the physical and mental health of patients. Due to the efficacy of acupuncture for tranquilization, acupuncture displays its unique advantage on the treatment of anxiety disorder, but the relevant biological mechanism has not been elaborated. The modern medicine study has proved that the heart and brain have their own independent natriuretic peptide (NP) system. The dysfunction of ANP and its receptor are closely related to the occurrence of anxiety disorder. The ANP acts on anti-anxiety. Hence, focusing on the three aspects, named the anti-anxiety effect of acupuncture based on its tranquilizing effect, the anti-anxiety effect of ANP and the positive regulation of acupuncture on NP, the mechanism on ANP and its receptor was explored in anti-anxiety with acupuncture based on tranquilizing effect, and the idea was put forward on that the anti-anxiety effect of acupuncture was possibly based on its action of tranquilization through regulating the ANP and its receptor. As a result, it is expected to provide the theoretic support for the mechanism study on anti-anxiety with acupuncture based on its tranquilizing effect.

Studies have found that depression is closely related to the hyperactivity of the hypothalamo–pituitary–adrenal (HPA) axis, which is manifested in increases in HPA axis-related hormones CRH, ACTH and CORT contents. Traditional Chinese medical acupuncture can down-regulate HPA axis levels to produce a marked antidepressant effect. However, at present there is no HPA axis mechanism analysis of the antidepressant effect of acupuncture. From two aspects: the relationship between depression and HPA axis, and clinical and animal mechanism studies of the antidepressant effect of acupuncture by regulating the HPA axis, an analysis has been made to provide a more powerful scientific basis and the idea of further in-depth study for clinical acupuncture treatment of depression.

Objective To explore the clinicopathologic factors impacting recurrence and survival in rectal cancer patients after radical resection.Methods Clinicopathologic data of 1 166 patients with rectal cancer in Changhai Hospital,were recruited between 2005 and 2010.Kaplan-Meier analysis and the logrank test were used to evaluate the effects of the pathology on patients' survival.Cox regression model was used to assess independent factors associated with clinical prognosis.Results The 1,3,5-year overall survival rates were 94.3%,81.2% and 76.5%,median survival time was 53 months.328 patients had recurrence and metastases,with a median recurrence time of 18 months.The independent prognostic factors for overall survival time were CEA,CA19-9,tumor distance to dentate line,surgical modality,radical operation,tumor invasion,tumor differentiation,lymph node metastasis and postoperative treatment.Surgical treatment,radical operation or not,tumor invasion and lymph node metastasis were statistically significant associated with tumor recurrence and metastases.Conclusions The important factors inffuencing the prognosis of rectal cancer patients were CEA,CA19-9,tumor distance to dentate line,surgical modality,radial operation,tumor in vasion,tumor differentiation,lymph node metastasis,and post operative treatment.

Objective: To describe the CT features and clinical characteristics of pediatric patients with coronavirus disease 2019 (COVID-19).Method: A total of 9 COVID-19 infected pediatric patients were included in this study.Clinical history,laboratory examination,and detailed CT imaging features were analyzed.All patients underwent the first CT scanning on the same day of being diagnosed by realtime reverse-transcription polymerase chain reaction (rRT-PCR).A low-dose CT scan was performed during follow-up.Results: All the child patients had positive results.Four patients had cough and one patient had fever.One patient presented both cough and fever.Two children presented other symptoms like sore throat and stuffy nose.One child showed no clinical symptom.Five patients had positive initial CT findings with subtle lesions like ground-glass opacity (GGO) or spot-like mixed consolidation.Three patients were reported with negative results in the initial and follow-up CT examination.One patient was reported with initial negative CT findings but turning positive during the first follow-up.All patients had absorbed lesions on follow-up CT images after treatment.Conclusion: Pediatric COVID-19 patients have certain imaging and clinical features as well as disease prognosis.Children with COVID-19 tend to have normal or subtle CT findings and relatively better outcome.
