Abstract
Papillary thyroid carcinoma (PTC) is generally recognized as a slow-growing tumor. However, a small subset of patients may still experience relapse or metastasis shortly after therapy, leading to a poor prognosis and raising concerns about excessive medical treatment. One major challenge lies in the inadequacy of effective biomarkers for accurate risk stratification. Long non-coding RNAs (lncRNAs), which are closely related to malignant characteristics and poor prognosis, play a significant role in the genesis and development of PTC through various pathways. The objective of this review is to provide a comprehensive summary of the biological functions of lncRNAs in PTC, identify prognosis-relevant lncRNAs, and explore their potential mechanisms in drug resistance to BRAF kinase inhibitors, tumor dedifferentiation, and lymph node metastasis. By doing so, this review aims to offer valuable references for both basic research and the prediction of PTC prognosis.

Abstract
The strict tolerance space of three-dimensional (3D) crystalline structures is still a significant challenge in the area of switching dielectrics in comparison with lower-dimensional structures. Generally, the function of crystalline materials can be given or adjusted by controlling the environment in which synthesis takes place or the packing rearrangement. Using this method, special functional enhancements or changes in the dielectrics can be realized by improving the synthetic strategies. Here, a 3D switchable dielectric compound [MeHdabco]K(BF4)3 was achieved by employing the temperature selective effect. In particular, its structure is completely different from the usual 3D perovskite structure, which is constructed using two different cation-template frameworks. Moreover, the 3D [MeHdabco]K(BF4)3 shows a structural phase transition at 358 K. The thermal analysis (differential scanning calorimetry (DSC)) and X-ray diffractometry results provided evidence of these phase changes. This work provides a feasible strategy that can be used to achieve the different structures of an 'isomer', and enrich the method used for designing diverse functional materials.

Abstract
β-Actin is an essential component of the cytoskeleton and is stably expressed in various tissues of animals, thus, it is commonly used as an internal reference for gene expression studies. In this study, a 1731-bp fragment of β-actin cDNA from Alligator sinensis was obtained using the homology cloning technique. Sequence analysis showed that this fragment contained the complete coding sequence of the β-actin gene (1128 bp), encoding 375 amino acids. The amino acid sequence of β-actin is highly conserved and its nucleotide sequence is slightly variable. Multiple alignment analyses showed that the nucleotide sequence of the β-actin gene from A. sinensis is very similar to sequences from birds, with 94-95% identity. Ten pairs of primers with different product sizes and different annealing temperatures were screened by PCR amplification, agarose gel electrophoresis, and DNA sequencing, and could be used as internal reference primers in gene expression studies. This study expands our knowledge of β-actin gene phylogenetic evolution and provides a basis for quantitative gene expression studies in A. sinensis.

Abstract
The influence of endothelin-1 on ventricular fibrillation threshold was studied in acute myocardial ischemic rats. Endothelin-1 (1.5-3.0 micrograms.kg-1 i.v.) given 5 min before ischemia reduced the ventricular fibrillation threshold in a dose- and time-dependent manner. Its effect lasted at least 60 min. A marked increase of spontaneous ventricular tachycardia and myocardial infarct size was seen and the arterial blood pressure was at a higher level (18.5-20.1/14.4-15.8 kPa) after 3.0 micrograms.kg-1. Diltiazem prevented partially from reduction of ventricular fibrillation threshold, eliminated completely the vasopressor response and limited the extension of myocardial necrosis induced by endothelin-1.

Abstract
The role of hypothalamic paraventricular nucleus (PVH) in acupuncture analgesia was investigated by local brain stimulation and cauterization. The results showed that electrical or L-glutamate sodium stimulation of PVH could enhance the effect of analgesia of Zusanli acupuncture, both in a dose dependent manner. Electrical cauterization of PVH decreased the effect of acupuncture analgesia, while removal of pituitary had no effect on the enhancing effect by L-glutamate sodium injection.

Abstract
STUDY OBJECTIVE Two selective V1 and V2 receptor antagonists of arginine vasopressin, d(CH2)5Tyr(Me)AVP and d(CH2)5[D-Ile2, Ile4, Ala9-NH2]AVP, were given intravenously in burn shocked rats to investigate the respective effects of V1 and V2 receptor blockade on the haemodynamic variables in burn shock. DESIGN Computer assisted on line real time measurements of mean arterial blood pressure, diastolic blood pressure, left ventricular systolic pressure, dP/dtmax, and heart rate were used to study the effects of the receptor antagonists during burn shock. In addition, the radioactive microsphere method was used to measure the changes of cardiac output and regional blood flows to heart, kidney, and liver in response to the antagonists during burn shock. Third degree burns extending over 30% of body surface area were made by dipping the rat's shaved back into water at 100 degrees C for 20 s. EXPERIMENTAL MATERIAL Male Sprague-Dawley rats (250-300 g) were used in groups of 6-9 per experiment. MEASUREMENTS AND MAIN RESULTS Mean and diastolic arterial blood pressures, left ventricular systolic pressure, dP/dtmax and heart rate were measured for 8 h after burns. Cardiac output and regional blood flow were measured at 3 h and 8 h postburn. Results showed that blockade of V1 receptor lowered mean and diastolic arterial blood pressures throughout the 8 h period, and raised left ventricular systolic pressure and dP/dtmax only during the early phase of shock. Cardiac output and blood flows to heart, kidney, and liver were increased by the V1 antagonist at 3 h but not at 8 h postburn. The V2 receptor antagonist increased mean and diastolic arterial blood pressures, left ventricular systolic pressure, and dP/dtmax both during the early and during the late phases of burn shock. It also improved cardiac output and blood flows to the heart, kidney, and liver during the early and late phases of burn shock. However, heart rate was not affected by V1 and V2 receptor antagonists. CONCLUSIONS The V2 like receptor may be the dominating receptor mediating vasopressin's inhibitory effect on the heart. V1 receptor mediated coronary vasoconstriction contributes to the myocardial depression possibly only at the compensatory phase of shock. In addition V1 receptor mediated vasoconstriction is important in maintaining blood pressure during burn shock.

Abstract
To investigate the effect of arginine vasopressin (AVP) in the peripheral circulation on burn shock in the rat, AVP and its nonselective V1/V2 receptor antagonist d(CH2)5Tyr (Et)VAVP were administered intravenously in burn shocked rats. Cardiovascular parameters were recorded including left ventricular systolic pressure (LVSP), +/- dP/dt max, total area of the cardiac force loop (Lo), mean arterial blood pressure (MAP), heart rate (HR) and electrocardiogram (ECG). Our results showed that AVP failed to increase MAP in burned rats whereas it elicited a greater fall in LVSP, +/- dP/dt max and Lo and MAP than seen in control burned rats and hastened the onset of the decompensatory phase of burn shock resulting in the early death of burn shocked animals. The receptor antagonist d(CH2)5Tyr(Et)VAVP elevated LVSP, +/- dp/dt max and Lo for the eight hour observation period, and allowed MAP to recover from the initial profound fall following burn injury. Furthermore, it prolonged the survival time of the burned rats. AVP treated rats also displayed earlier abnormal changes such as elevation of S-T segment, inversion of T wave and ventricular fibrillation in ECG. The onset of these changes was much delayed in antagonist treated rats.

Abstract
Changes in the somatostatin-like immunoreactivity (SLI) concentrations in gastric antral mucosa were detected by RIA following microinjections of synthetic somatostatin (SS) or cysteamine (CSH) into the ventromedial nucleus of the hypothalamus (VMH). SLI concentrations in the antral mucosa were increased by 60.8% (p less than 0.001) and 42.3% (p less than 0.05), respectively, one and four hours after microinjection of somatostatin (0.5 microgram/0.5 microliter) into the VMH, and decreased by 32.6% (p less than 0.05) four hours after microinjection of cysteamine (15 microgram/0.5 microliter) into the VMH. Moreover, microinjection of somatostatin (0.5 microgram/0.5 microliter) into the VMH could only elicit an increase of 16.0% (p less than 0.05) in the SLI concentration in the antral mucosa one hour after bilateral subdiaphragmatic vagotomies, but still produced an increase of 120.0% (p less than 0.05) following celiac ganglionectomies. In conclusion, somatostatin (exogenous and endogenous) in the VMH seems to affect the gastric somatostatin levels via the vagal nerves.

Abstract
The effects of intraventricular injection (ICV) of oxytocin (OT) and antioxytocin serum (AOTS) on the pain threshold and electroacupuncture (EA) analgesia in rats were investigated in this study. The potassium iontophoresis induced tailflick was used to measure the pain threshold. An increase of 20-38% in the pain threshold was observed within 80 min after OT injection (50 ng), while the OT administration (50 ng) in combination with EA produced a dramatic increase of 139-234% in the pain threshold, which was much higher than that in the saline-EA group (P less than 0.05 or 0.01). The OT effect was dose-related in the range between 25-100 ng. Although ICV of AOTS did not change the pain threshold, the EA analgesia became weakened significantly. After injection of AOTS, EA only produced an increase of 47-61% in the pain threshold, while following ICV injection of normal rabbit serum instead of AOTS the EA could cause a rise of 104-123% in the pain threshold. There was a significantly statistical difference between the above two groups (P less than 0.05-0.01). The data indicate that ICV of OT not only elevates the pain threshold, but also enhances the EA effect, and that AOTS attenuates the EA analgesia. These results suggest that endogenous oxytocin in the central nervous system may play a role in the electroacupuncture analgesia.

Abstract
The effect of intracerebroventricular injections of arginine vasopressin (AVP) on burn shock in the rat and its possible mechanism were explored in this study. AVP was administered intraventricularly at 30 min intervals (50 ng) in the burned rats. The arterial pressure and electrocardiogram (ECG) were recorded with a multipurpose polygraph before and after burn. Compared with the control, the MAP of the rats in the AVP group was elevated at the initial stage and fell dramatically at the late stage of burn shock with a higher mortality. The ECG of the rats in the AVP group also displayed earlier changes such as elevation of S-T segment, inversion of T wave, and ventricular fibrillation. These findings suggest an unfavorable role of AVP in burn shock. The plasma, hypothalamic, and anterior and posterior pituitary levels of beta-endorphin 3 hr after burn were measured by radioimmunoassay. The increased level of beta-endorphin in the plasma after AVP treatment indicates the possible involvement of beta-endorphin in the deteriorating effect of AVP on burn shock.
