Abstract
The nervous system is the necessary condition for inducing the curative effect of acupuncture. Both the sympathetic and vagal nerve systems are widely distributed throughout the body and organically connect various systems and organs of the human body. In maintaining the coordination and unity of human physiological activities, it is in line with the holistic view and bidirectional regulation of acupuncture, and fits in with the meridian theory of "internally belonging to the Zang-fu organs and externally connecting with the limbs and joints". Acupuncture, one of the body surface stimulation therapies, can inhibit the inflammatory response via activating sympathetic/vagus nerve mediated anti-inflammatory pathways. The peripheral nerve innervating diffe-rent acupoints determines the different anti-inflammatory pathways of the autonomic nerve, and different acupuncture methods (stimulation form and stimulation amount) are important factors affecting the anti-inflammatory mechanism of the autonomic nerve. In the future, we should analyze the central integration mechanism between sympathetic nerve and vagus nerve regulated by acupuncture at the level of brain neural circuits, and clarify the "multi-target" advantage of acupuncture, so as to provide inspiration and reference for the study of neuroimmunological effects of acupuncture.

Abstract
The inflammatory response plays an important role in the onset, development and prognosis of inflammatory diseases and a variety of chronic diseases. Long-term uncontrolled inflammatory response may lead to dysfunction or loss of organ tissue function. Clinical practice and evidence-based medicine suggest that acupuncture can effectively alleviate the inflammatory status of various inflammatory diseases and chronic diseases. Stimulation of acupoints related to internal organs and target organs can initiate neuromodulation by modulating the microenvironment of acupoints. After integration of acupuncture stimulus information in the central nervous system, neurotransmitters, hormones, etc. are released and ultimately act on immune cells through neuro-endocrine-immune pathways, such as the vagus-mediated cholinergic anti-inflammatory pathway, vagus nerve-adrenal medullary-dopamine pathway, somatic sympathetic nerve pathway, and hypothalamic-pituitary-adrenal axis, etc. Ultimately, the intracellular signaling pathways and polarization balance of monocytes/macrophages and T cell subsets are regulated and the immune homeo-stasis of target organs of the body realizes. Therefore, we proposed that the anti-inflammatory action of acupuncture may be one of the universal therapeutic strategies for multiple diseases, and a powerful interpretation of acupuncture in regulating the balance of yin and yang. The elucidation of its anti-inflammatory action rules and mechanism may better realize the clinical transformation of acupuncture and moxibustion precision treatment.

Abstract
Autonomic dysfunction can lead to many physical and psychological diseases. The assessment of autonomic regulation plays an important role in the prevention, diagnosis, and treatment of these diseases. A physiopathological mathematical model for cardiopulmonary autonomic regulation, namely Respiratory-Autonomic-Sinus (RSA) regulation Model, is proposed in this study. A series of differential equations are used to simulate the whole process of RSA phenomenon. Based on this model, with respiration signal and ECG signal simultaneously acquired in paced deep breathing scenario, we manage to obtain the cardiopulmonary autonomic regulation parameters (CARP), including the sensitivity of respiratory-sympathetic nerves and respiratory-parasympathetic nerves, the time delay of sympathetic, the sensitivity of norepinephrine and acetylcholine receptor, as well as cardiac remodeling factor by optimization algorithm. An experimental study has been conducted in healthy subjects, along with subjects with hypertension and coronary heart disease. CARP obtained in the experiment have shown their clinical significance.

Abstract
Background Although minimally invasive surgery for colorectal cancer, whether performed as standard laparoscopic or robotic surgery, has been established as an oncologically safe procedure, postoperative urinary dysfunction and sexual dysfunction remain matters of concern, even when so-called nerve-sparing surgery is performed. We have hypothesized that Raman spectroscopy can be used intraoperatively as a non-invasive label-free means of objective identification of the pelvic nerves, and we conducted a preliminary study by applying a newly developed handheld Raman spectrometer to surgical specimens. Methods Samples of nervous tissue, colon cancer tissue, and tissues from surrounding pelvic organs were obtained from 25 patients undergoing colectomy. Raman spectra were obtained by irradiation with the Progeny™ Raman spectrometer. We looked for characteristic Raman shifts to distinguish nervous tissue from cancer tissue. To improve discrimination between nervous tissue and other tissues, the spectral data were subjected to principal component analysis. Results We detected characteristic differences in the spectra at 1,309 cm-1, 1,442 cm-1, and 1,658 cm-1. A significant difference was detected at 1,442 cm-1, and accuracy of the modality for identification of nervous tissue was 75%. The addition of principle component analysis (4 components) yielded 100% sensitivity, 85% specificity, and 90%, notably increasing accuracy from 75% to 90% in discriminating between nervous tissue and cancer tissue. Conclusions Raman spectroscopy holds promise for non-invasive intraoperative recognition of nervous tissue. We expect the modality to become a powerful clinical tool, compensating for the lack of tactile feedback intrinsic to minimally invasive colectomy and thus thwarting the risk of postoperative urinary and/or sexual dysfunction.

Abstract
OBJECTIVE To investigate the effect characteristics and mechanism of acupuncture in autonomic nerve regulation through a comprehensive literature analysis. METHODS CNKI and PubMed databases were searched for the studies on acupuncture in autonomic nerve regulation in the past 30 years, and Excel was used to perform a descriptive analysis of research subjects, intervention methods, intervention sites (acupoint selection), intervention parameters, and effect mechanism of acupuncture. RESULTS A total of 202 studies were included, among which there were 51 clinical studies, mostly on the nervous system and the circulatory system; Neiguan (PC6), Zusanli (ST36), Fengchi (GB20), and Hegu (LI4) were the most frequently used acupoints, manual acupuncture was the most common intervention method, most of the acupoints selected were in the extremities, head, face, and neck, and heart rate variability was the main parameter for evaluation. Among the 151 animal experimental studies, there were many studies on the digestive system and the circulatory system; "Zusanli" (ST36), "Neiguan" (PC6), and "Shenmen" (HT7) were the most frequently used acupoints, electroacupuncture was the most common intervention method, most of the acupoints selected were in the extremities, and the main effect mechanism was to regulate the central vagus nerve activity and the cholinergic anti-inflammatory pathway (CAP). CONCLUSION Acupuncture has a good effect on autonomic nerve regulation. The acupoints in extremities, head, and face are mainly used in studies. The main action pathways are central vagus nerve activity and CAP, as demonstrated in the animal experiments. Acupuncture has specific effect characteristics, which are closely associated with the acupoints, methods, and parameters of stimulation.

Abstract
This study developed a new method using radiopaque markers under X-ray to measure rat colonic transit by geometric center repeatedly and/or over a time series in the same individually. Additionally, the utility of this method was shown by elucidating the innervation of the autonomic nerve on colonic transit in detail with a pharmacological technique in conscious rats. An in-dwelling silastic cannula was inserted into the cecum and the proximal part was moved through the abdominal wall, where it was fixed to the posterior neck skin. Twenty markers were administered from the cannula to the proximal colon with saline on the fifth day after surgery. The markers were observed with soft X-ray before required repeated short anesthesia. Experimentation 1: Rats were measured colonic transit twice over 2 days with no administration. Experimentation 2: Rats were administered saline on the first day and pharmacology on the second day intraperitoneally before measurement. Experimentation 1: The markers administrated from the cannula and transited from proximal colon to distal colon over a time series. It showed no significant difference in complication rates between 2 days. Experimentation 2: The colonic transit was increasingly accelerated by neostigmine and phentolamine but not propranolol. Significant changes in 1.0 mg/kg atropine were noted although no differences were found between control and 0.05 mg/kg atropine and between each other's. We have presented the method using radiopaque markers under X-ray with short anesthesia for evaluating the colonic transit. The methods could show rat colonic transit changes in detail with a pharmacological technique.

Abstract
PURPOSE The autonomic nervous system, consisting of sympathetic and parasympathetic/vagal nerves, is known to control the functions of any organ, maintaining whole-body homeostasis under physiological conditions. Recently, there has been increasing evidence linking sympathetic and parasympathetic/vagal nerves to cancers. The present review aimed to summarize recent developments from studies addressing the relationship between sympathetic and parasympathetic/vagal nerves and cancer behavior. METHODS Literature review. RESULTS Human and animal studies have revealed that sympathetic and parasympathetic/vagal nerves innervate the cancer microenvironment and alter cancer behavior. The sympathetic nerves have cancer-promoting effects on prostate cancer, breast cancer, and melanoma. On the other hand, while the parasympathetic/vagal nerves have cancer-promoting effects on prostate, gastric, and colorectal cancers, they have cancer-suppressing effects on breast and pancreatic cancers. These neural effects may be mediated by β-adrenergic or muscarinic receptors and can be explained by changes in cancer cell behavior, angiogenesis, tumor-associated macrophages, and adaptive antitumor immunity. CONCLUSIONS Sympathetic nerves innervating the tumor microenvironment promote cancer progression and are related to stress-induced cancer behavior. The parasympathetic/vagal nerves have variable (promoting or suppressing) effects on different cancer types. Approaches directed toward the sympathetic and parasympathetic/vagal nerves can be developed as a new cancer therapy. In addition to existing pharmacological, surgical, and electrical approaches, a recently developed virus vector-based genetic local neuroengineering technology is a powerful approach that selectively manipulates specific types of nerve fibers innervating the cancer microenvironment and leads to the suppression of cancer progression. This technology will enable the creation of "cancer neural therapy" individually tailored to different cancer types.

Abstract
BACKGROUND Vitamin C (VC) is a common antioxidant with cell protection potentials. However, its possible protective effect on cardiac autonomic nerves from diabetic induced insults is yet to be explored.
AIM To investigate the effects of VC on diabetic cardiac autonomic neuropathy.
METHODS Thirty male Wistar rats were equally grouped into control, diabetic and diabetic + VC. Type 2 diabetes was induced with fructose diet and alloxan. VC (1 g/kg) was administered for 4 wk via oral canula. Blood pressure and heart rate were measured non-invasively using tail flick blood pressure monitor. Spectral analysis of heart rate variability (HRV) was used to assess cardiac autonomic neuropathy. Blood was collected from the ocular sinus for biochemical analysis. Urethane (1 g/kg-ip) was used for anaesthesia prior to HRV and cervical dislocation to harvest hearts. Intracardiac autonomic nerve was assessed using tyrosine hydroxylase immunohistochemistry on fixed heart sections.
RESULTS Results were analysed using ANOVA at α0.05. Unlike VC and control groups, diabetic rats showed significantly (P < 0.0001) reduced HRV, increased heart-rate and blood pressure, initial increase in cardiac tyrosine hydroxylase activities at week-2 and sparse activity at week-4 of diabetes. Furthermore, apolipoprotein B, Oxidative stress and inflammatory markers were significantly (P < 0.01) reduced in VC treated rats.
CONCLUSION VC possesses cardio-autonomic nerve protective potential and ameliorates the symptoms of cardiac autonomic neuropathy in type 2 diabetes. The possible mechanisms via which VC exert these effects may be via downregulation of oxidative stress, inflammation and apolipoprotein B.

Abstract
Fragrance inhalation of essential oils is widely used in aromatherapy, and it is known to affect blood pressure (BP) and heart rate (HR) via autonomic control of circulation. In this study, we aimed to test the hypothesis that the changes in hemodynamics with fragrance inhalation were observed along with changes in muscle sympathetic nerve activity (MSNA). In study 1, thirteen healthy men were exposed to fragrance stimulation of grapefruit essential oil for 10 min, and BP, HR, and MSNA were continuously measured. In study 2, another nine healthy men were exposed to the same fragrance stimulation; responses in BP and HR were continuously measured, and plasma noradrenaline and cortisol concentrations were determined. We found that diastolic BP increased significantly during fragrance inhalation, while the other variables remained unchanged in both studies. Although MSNA burst frequency, burst incidence, and total activity remained unchanged during fragrance inhalation, we found a significant linear correlation between changes in diastolic BP in the last 5 min of fragrance inhalation and changes in MSNA burst frequency. The plasma cortisol concentration decreased significantly at 10 min of fragrance inhalation, though the noradrenaline concentration remained unchanged. These results suggest, for the first time, that changes in BP with fragrance inhalation of essential oil are associated with changes in MSNA even with decreased stress hormone.

Abstract
BACKGROUND Renal artery catheter ablation has been reported as a possible therapeutic option for drug-refractory ventricular arrhythmias (VAs) associated with structural heart diseases. OBJECTIVE To further clarify its therapeutic background, we examined the relationship between electrical nerve stimulation (ENS)-induced blood pressure (BP) elevation and occurrence of VAs by using an acute canine model of renal artery ablation. METHODS Using a decapolar electrode catheter, ENS was successively applied from the distal, mid, and proximal segments of the renal artery in 8 beagles. The same ENS was repeated after accomplishment of radiofrequency ablation at the ostial site of the renal artery by using an irrigation catheter. RESULTS Before ablation, ENS increased BP from 140 ± 11/77 ± 11 to 167 ± 20/98 ± 16 mm Hg and heart rate from 100 ± 21 to 131±33 beats/min as well as induced VAs in 20 of the 45 ENS applications. Occurrence of VAs was associated with a greater magnitude of sympathetic nerve augmentation, and VAs were more frequently observed by ENS at the distal (67%) rather than mid/proximal segments of the renal artery (33%). Renal artery ablation was accomplished without any angiographic stenosis, and ENS-induced BP elevation, heart rate acceleration, and VAs occurrence were attenuated not only at the close segment (proximal) but also at the remote segments (mid/distal) of the renal artery. CONCLUSION The renal autonomic nerves are considered as one of the therapeutic targets for suppression of frequent VAs because its activation has arrhythmogenic potential and induces premature ventricular beats.

Abstract
AIMS Changes in cardiac autonomic nervous function have been evaluated by studying the related indexes of heart rate variability (HRV) in patients with focal epilepsy (FE) in the interictal period. MAIN METHODS A total of 30 FE patients who were treated in our department from July 2015 to May 2017, were included into this study. These patients were divided into three pairs of groups: less frequent seizure group and more frequent seizure group; medication group and non-medication group; <10 years disease group and ≥10 years disease group. In addition, 16 normal healthy subjects were enrolled as the control group. The time domain and frequency domain indexes of HRV indexes between subgroups and the control group were retrospectively analyzed. KEY FINDINGS The low-frequency/high-frequency ratio (LF/HF) in the interictal period was higher in the more frequent seizure group than in the control group and less frequent seizure group (P < 0.05). Furthermore, differences in interictal LF/HF and very low frequency (VLF) between the medication group and non-medication group and control group were statistically significant (P < 0.05). SIGNIFICANCE In interictal period FE patients who present with an imbalance in autonomic nervous function, LF/HF can serve as an indicator to evaluate the interictal cardiac sympathetic activity of FE patients. Furthermore, the dynamic observation of changes in the HRV-related indexes of FE patients can prevent the choice of antiepileptic drugs that affect heart function, which is of guiding significance for evaluating autonomic nervous function.

Abstract
To date, various signal transducers, cytokines, growth factors, and hormones have been reported to play an important role in homeostasis of various organs. Various cells and organs are involved in the hepatic regeneration process, which proceeds as a result of the coordination of many factors. While these factors are well known to be involved in the liver regeneration after the liver injury, however, as the details of such mechanisms have not been sufficiently elucidated, the practical applicability of hepatic regeneration based on the action of these and cytokines growth factors is still unclear. In terms of the involvement of the autonomic nervous system in hepatic regeneration, cell proliferation resulting from direct signal transduction to the liver has also been reported and recent studies focusing on the inter-organ communication via neural network opened a novel aspect of this field for therapeutic applicability. Therefore, the appropriate understanding of the relationship between autonomic neural network and liver regeneration through various organs including brain, afferent nerve, efferent nerve, etc. is essential. This mini-review explains the principle of neural system involved in the inter-organ communication and its contribution on the liver regeneration upon the liver injury reviewing recent progress in this field.

Abstract
BACKGROUND Postoperative urinary dysfunction is a major complication of rectal cancer surgery. A randomized controlled trial (JCOG0212) concluded that the noninferiority of mesorectal excision alone to mesorectal excision with lateral lymph node dissection was not confirmed in terms of relapse-free survival. METHODS Eligibility criteria included histologically proven clinical stage II/III rectal cancer, a main lesion located in the rectum with the lower margin below the peritoneal reflection, and the absence of lateral lymph node enlargement. After confirming R0 resection by mesorectal excision, patients were randomized intraoperatively. The residual urine volume was measured three times. Urinary dysfunction was defined as ≥50 mL residual urine occurring at least once or no measurement of residual urinary volume. This trial was registered with the UMIN Clinical Trials Registry, number C000000034. RESULTS In the mesorectal excision alone and the mesorectal excision with lateral lymph node dissection groups, the incidence of early urinary dysfunction were 58% and 59%, respectively. A tumor location in the lower rectum (vs. upper rectum) and a blood loss of ≥500 mL (vs. <500 mL) were associated with an increased risk of early urinary dysfunction. However, only blood loss was independently predictive of early urinary dysfunction (relative risk, 1.25 [95% CI: 1.10-1.55], p = .04). CONCLUSIONS Mesorectal excision with lateral lymph node dissection is not associated with a significant increase in the incidence of urinary dysfunction. Urinary dysfunction is associated with tumor location and blood loss.

Abstract
BACKGROUND Psychophysiological symptoms (e.g., pounding heart) are known to be a prominent feature of post-traumatic stress disorder (PTSD). Although omega-3 polyunsaturated fatty acids (PUFAs) have a beneficial potential pharmacological effect of preventing these psychophysiological symptoms, no clinical data is yet available. Therefore, we conducted a randomized, double-blind, placebo-controlled trial of Japanese accident survivors. METHODS A total of 83 participants received either omega-3 PUFAs (1470mg docosahexaenoic acid and 147mg eicosapentaenoic acid per day) or placebo within 10 days of the accidental injury. After 12-week supplementation, participants performed script-driven imagery of their traumatic event during monitoring of their heart rate and skin conductance. RESULTS Analysis revealed that heart rate during both rest and script-driven imagery was significantly lower in the omega-3 group than the placebo group, whereas baseline heart rate was comparable between the two groups. LIMITATIONS The present trial was conducted at a single-center in Japan and psychophysiological symptoms of PTSD in most participants were not serious. CONCLUSION These findings suggest that post-trauma supplementation of omega-3 PUFAs might be effective for the secondary prevention of psychophysiological symptoms of PTSD.

Abstract
The periosteal arterioles of the compact bone may play a critical role in bone growth. To explore the contractile properties of tibial arterioles, spontaneous and nerve-evoked constrictions were compared in preparations from 3-week-old and 1-year-old guinea-pigs. Changes in arteriole diameters were measured using video microscopy. Their innervation was investigated using fluorescence immunohistochemistry. Fifty per cent and 40% of tibial arterioles from 3-week-old and 1-year-old guinea-pigs, respectively, exhibited spontaneous phasic constrictions that were inhibited by 1 μM nifedipine, 10 μM cyclopiazonic acid or 100 μM 2-APB. Nerve-evoked phasic constrictions in both age groups were largely suppressed by phentolamine (1 μM), an α-adrenoceptor antagonist, or sympathetic neurotransmitter depletion using guanethidine (10 μM) but were enhanced by spanttide (1 μM), a substance P receptor antagonist, or L-nitro arginine (L-NA; 100 μM), an inhibitor of nitric oxide synthase (NOS). Nerve-evoked constrictions in 1-year-old animals were smaller than those in younger animals but greatly enhanced by L-NA. Immunohistochemistry revealed sympathetic and substance P-positive primary afferent nerves running along the arterioles as well as endothelial NOS expression in both age groups. Spontaneous arteriolar constrictions appear to rely on both Ca2+ release from the sarcoplasmic reticulum and Ca2+ influx through L-type Ca2+ channels. Noradrenaline released from sympathetic nerves triggers arteriolar constriction, while substance P released from primary afferent nerves dilates the arterioles by releasing nitric oxide (NO), presumably from the endothelium. Thus, the enhanced endothelial NO release in adult guinea-pigs may be important to increase the blood supply to meet the increased metabolic demands during bone growth.

Abstract
Laparoscopic radical hysterectomy has been widely performed for patients with early-stage cervical cancer. The operative techniques for nerve-sparing to avoid bladder dysfunction have been established during the past three decades in abdominal radical hysterectomy, but how these techniques can be applied to laparoscopic surgery has not been fully discussed. Prolonged operation time or decreased radicality due to less accessibility via a limited number of trocars may be a disadvantage of the laparoscopic approach, but the magnified visual field in laparoscopy may enable fine manipulation, especially for preserving autonomic nerve tracts. The present review article introduces the practical techniques for sparing bladder branches of pelvic nerves in laparoscopic radical hysterectomy based on understanding of the pelvic anatomy, clearly focusing on the differences from the techniques in abdominal hysterectomy.

Abstract
Background Perineural invasion has been found in several types of human tumors, and is associated with poor prognosis; however, few studies have examined perineural invasion in lung cancer. We evaluated the relationship between autonomic nervous densities, pathological risk grading, and prognosis in patients with lung adenocarcinoma (LADC). Methods Neural fiber expression was examined by immunofluorescence in resected lung specimens in control patients (n = 30), and low‐risk (n = 22), and high‐risk LADC patients (n = 43). The nerve densities of normal lung tissue and abnormal lung tissues in the tumor and surrounding tissues were evaluated by a semi‐quantitative score method. Results Increased sympathetic fibers mainly infiltrated the paratumoral area, while increased parasympathetic fibers were largely restricted to the tumor (paratumor vs. tumor, P = 0.000 in high, P = 0.034 in low; each). In addition, high‐risk patients presented the highest density of neural fibers, followed by low‐risk and control patients (P = 0.000; each). In Kaplan–Meier survival analysis, the densities of sympathetic fibers in paratumoral tissue and parasympathetic fibers in the tumor, respectively, correlated with poor recurrence‐free survival in patients who were not treated with adjuvant therapy (P < 0.001; each). Further multivariate analysis showed that these two factors were associated with poor prognosis in all LADC patients (P = 0.024 sympathetic fibers; P = 0.037 parasympathetic fibers). Conclusion These findings reveal a positive correlation between nervous infiltration and risk of poor prognosis in patients with LADC.

Abstract
BACKGROUND CO2-pneumoperitoneum can cause sympathetic nerve activity increased and is likely to causes severe stress-related homeostatic disorders. OBJECTIVE Patients undergoing elective laparoscopic cholecystectomy were administered type-B ultrasound-guided stellate ganglion block (SGB) to observe the effects on autonomic nervous system during CO2- pneumoperitoneum. DESIGN A randomized, double-blinded, and placebo-controlled study. SETTING University-affiliated teaching hospital. PATIENTS Eighty patients (aged 32-75 years; weight, 45-80 kg; American Society of Anesthesiologists (ASA) physical status classification, class I or II) undergoing elective laparoscopic cholecystectomy. INTERVENTIONS The RSGB group was administered lidocaine 1% 7 ml under ultrasound guidance. MAIN OUTCOME MEASURES The low frequency (LF), high frequency (HF), total power (TP) and LF/HF ratio were recorded before the block (T0), 5 min (T1) and 30 min (T2) following pneumoperitoneum, 5 min after deflation of pneumoperitoneum (T3) and after surgery (T4). The low-frequency normalized unit (LFnu) and high-frequency normalized units (HFnu) were calculated. RESULTS Compared with T0, LF, LFnu and LF/HF ratio were significantly elevated at T1-4 (all P< .05 or .01). HFnu was significantly decreased at T2-4 in control group (P< .05) while HF was significantly elevated (P< .01). The LF/HF ratio was significantly decreased (P< .05) at T1-4 in RSGB group. Compared with control group, the LF, LFnu and LF/HF ratio were significantly decreased (P< .05) and HF and HFnu was significantly elevated (P< .05 or .01) at T1-4 in RSGB group. CONCLUSION Ultrasound-guided RSGB inhibited CO2-pneumoperitoneum-induced sympathetic neural excitation, upregulated vagal nerve stimulation and maintained stable autonomic nervous function.

Abstract
OBJECTIVES Nerve-sparing techniques to avoid bladder dysfunction in abdominal radical hysterectomy have been established during the past two decades, and they have been applied to radical trachelectomy. Although trachelectomy retains the uterine corpus, no report mentions the preservation of uterine branches of pelvic nerves. The aim of the present study was to introduce and discuss our unique concept for preserving them. STUDY DESIGN AND RESULTS Four cases with FIGO stage Ia2-Ib1 cervical cancer, in which preservation of uterine branches of the pelvic nerves was attempted, are presented. Operative procedures basically followed the previously reported standard approaches for nerve-sparing radical hysterectomy or trachelectomy, except for some points. Before resection of the sacrouterine ligament, the hypogastric nerve was first identified and translocated laterally. Subsequently, the uterine branches of the pelvic nerve were identified as a continuation of the hypogastric nerve and could be scooped with forceps by detachment of the surrounding connective tissues. Further detachment toward the uterine corpus enabled them to be completely separated from the cervix. This separation was extended up to the level of the junction of the upper and lower branches of the uterine artery. Thereafter, standard resection of the parametrium and paracolpium was performed, followed by cervical resection when it was confirmed that the isolated uterine branches of the pelvic nerves were safely translocated and preserved. There were no recurrences of cancer in these patients. CONCLUSIONS Uterine branches of autonomic nerves can be safely preserved, and the procedure may be considered one of the nerve-sparing techniques for radical abdominal trachelectomy, which may hopefully improve the reproductive outcomes of this operation, although it needs to be evaluated with more patients.

Abstract
AIM: To investigate the mechanism of gastric mucosal demage induced by water immersion restraint stress (WRS) and its prevention by growth hormone releasing peptide-6 (GHRP-6).
METHODS: Male Wistar rats were subjected to conscious or unconscious (anesthetized) WRS, simple restraint (SR), free swimming (FS), non-water fluid immersion, immersion without water contact, or rats were placed in a cage surrounded by sand. To explore the sensitivity structures that influence the stress reaction besides skin stimuli, a group the rats had their eyes occluded. Cervical bilateral trunk vagotomy or atropine injection was performed in some rats to assess the parasympathetic role in mucosal damage. Gastric mucosal lesions, acid output and heart rate variability were measured. Plasma renin, endothelin-1 and thromboxane B2 and gastric heat shock protein 70 were also assayed. GHRP-6 was injected [intraperitoneal (IP) or intracerebroventricular (ICV)] 2 h before the onset of stress to observe its potential prevention of the mucosal lesion.
RESULTS: WRS for 6 h induced serious gastric mucosal lesion [lesion area, WRS 81.8 ± 6.4 mm2vs normal control 0.0 ± 0.0 mm2, P < 0.01], decreased the heart rate, and increased the heart rate variability and gastric acid secretion, suggesting an increase in vagal nerve-carrying stimuli. The mucosal injury was inversely correlated with water temperature (lesion area, WRS at 35 °C 56.4 ± 5.2 mm2vs WRS at 23 °C 81.8 ± 6.4 mm2, P < 0.01) and was consciousness-dependent. The injury could not be prevented by eye occlusion, but could be prevented by avoiding contact of the rat body with the water by dressing it in an impermeable plastic suit. When water was replaced by vegetable oil or liquid paraffin, there were gastric lesions in the same grade of water immersion. When rat were placed in a cage surrounded by sand, there were no gastric lesions. All these data point to a remarkable importance of cutenuous information transmitted to the high neural center that by vagal nerves reaching the gastric mucosa. FS alone also induced serious gastric injury, but SR could not induce gastric injury. Bilateral vagotomy or atropine prevented the WRS-induced mucosal lesion, indicating that increased outflow from the vagal center is a decisive factor in WRS-induced gastric injury. The mucosal lesions were prevented by prior injection of GHRP-6 via IP did, but not via ICV, suggesting that the protection is peripheral, although a sudden injection is not equivalent to a physiological release and uptake, which eventually may affect the vagal center.
CONCLUSION: From the central nervous system, vagal nerves carry the cutaneous stimuli brought about by the immersion restraint, an experimental model for inducing acute gastric erosions. GHRP-6 prevents the occurrence of these lesions.

Abstract
AIM: To study correlations of psychological and autonomic nerve changes and gastric electrical activity in functional dyspepsia (FD).
METHODS: Eighty FD patients and 30 healthy normal individuals were tested using the Hamilton Depression (HAMD), Hamilton Anxiety (HAMA) and SCL-90 scales and heart rate variability and electrogastrography.
RESULTS: The FD patients showed some abnormalities in psychology, autonomic nerve and gastric electrical activity, demonstrating more obvious changes than normal people (P < 0.01). The influence of psychological change on the autonomic nerve was greater and had more oscillation (P < 0.01, C = 0.4908) than that of the autonomic nerve on psychological state (P < 0.05, C = 0.2519). The influences of autonomic nerves and gastric electric activity were equal (P < 0.01, C = 0.4279). There was no relationship between psychological change and gastric electric activity (P > 0.05, C = 0.1866).
CONCLUSION: FD patients were more influenced by psychological changes affecting the autonomic nerve than were healthy normal individuals. Changes of the autonomic nerve and gastric electric activity were related, whereas psychological changes and gastric electric activity were not directly related.
