Abstract
Diets rich in taurine can increase the production of taurine-conjugated bile acids, which are known to exert antihypertensive effects. Despite their benefits to the heart, kidney and arteries, their role in the central nervous system during the antihypertensive process remains unclear. Since hypothalamic paraventricular nucleus (PVN) plays a key role in blood pressure regulation, we aimed to investigate the function of bile acids in the PVN. The concentration of bile acids in the PVN of spontaneously hypertensive rats (SHRs) and normotensive Wistar-Kyoto rats (WKY) fed with normal chow was measured using LC-MS/MS, which identified taurocholic acid (TCA) as the most down-regulated bile acid. To fully understand the mechanism of TCA's functions in the PVN, bi-lateral PVN micro-infusion of TCA was carried out. TCA treatment in the PVN led to a significant reduction in the blood pressure of SHRs, with decreased plasma levels of norepinephrine and improved morphology of cardiomyocytes. It also decreased the number of c-fos+ neurons, reduced the inflammatory response, and suppressed oxidative stress in the PVN of the SHRs. Most importantly, the TGR5 receptors in neurons and microglia were activated. PVN infusion of SBI-115, a TGR5 specific antagonist, was able to counteract with TCA in the blood pressure regulation of SHRs. In conclusion, TCA supplementation in the PVN of SHRs can activate TGR5 in neurons and microglia, reduce the inflammatory response and oxidative stress, suppress activated neurons, and attenuate hypertension.

Abstract
The pathogenesis of attention-deficit/hyperactivity disorder (ADHD) has not been fully elucidated. Gestational hypertension could double the probability of ADHD in the offspring, while the initial bacterial communication between the mother and offspring has been associated with psychiatric disorders. Thus, we hypothesize that antihypertensive treatment during pregnancy may abate the impairments in neurodevelopment of the offspring. To test this hypothesis, we chose Captopril and Labetalol, to apply to pregnant spontaneously hypertensive rat (SHR) dams and examined the outcomes in the male offspring. Our data demonstrated that maternal treatment with Captopril and Labetalol had long-lasting changes in gut microbiota and behavioral alterations, including decreased hyperactivity and increased curiosity, spatial learning and memory in the male offspring. Increased diversity and composition were identified, and some ADHD related bacteria were found to have the same change in the gut microbiota of both the dam and offspring after the treatments. LC-MS/MS and immunohistochemistry assays suggested elevated expression of brain derived neurotrophic factor (BDNF) and dopamine in the prefrontal cortex and striatum of offspring exposed to Captopril/ Labetalol, which may account for the improvement of the offspring's psychiatric functions. Therefore, our results support the beneficial long-term effects of the intervention of gestational hypertension in the prevention of ADHD.

Abstract
AIM To analyze the distribution of refractive status in school-age children with different corneal curvatures (CC) and the correlation between CC and refractive status. METHODS A total of 2214 school-aged children of grade 4 in Hangzhou who were screened for school myopia were included. Uncorrected distance visual acuity (UCDVA), non-cycloplegic refraction, axial length (AL), horizontal and vertical corneal curvature (K1, K2) were measured and spherical equivalent (SE), corneal curvature radius (CCR) and axial length/corneal radius of curvature ratio (AL/CR) were calculated. UCDVA<5.0 and SE≤-0.50 D were classified as school-screening myopia. According to the different CCRs, the patients were divided into the lower corneal curvature (LCC) group (CCR≥7.92) and the higher corneal curvature (HCC) group (CCR<7.92). Each group was further divided into the normal AL subgroup and the long AL subgroup. The refractive parameters were compared to identify any differences between the two groups. RESULTS Both SE and AL were greater in the LCC group (P=0.013, P<0.001). The prevalence of myopia was 38% in the LCC group and 44% in the HCC group (P<0.001). The proportion of children without screening myopia was higher in the LCC group (62%) than in the HCC group (56%). Among these children without screening myopia, the proportion of long AL in the LCC group (24%) was significantly higher than that in the HCC group (0.012%; P<0.001). The change of SE in the LCC group was less affected by the increase of AL than that in the HCC group. CONCLUSION School-aged children in the LCC group have a lower incidence of screening myopia and longer AL. Low CC can mask SE reduction and AL growth to some extent, and the change of AL growth change more in children with low CC than high CC. Before the onset of myopia, its growth rate is even faster than that after the onset of myopia.

Abstract
Objective: To study the complete genome characterization of Human Astrovirus (HAstV) in Shandong Province. Methods: Stool samples from acute flaccid paralysis (AFP) surveillance in Shandong Province from 2020 to 2022 were collected, and HAstV nucleic acid was examined by real-time quantitative PCR (qPCR). Next-generation sequencing (NGS) was conducted for the positive samples to obtain complete genome sequences and identify the genotype. Homology comparison and phylogenetic analysis were performed by using BioEdit and Mega software. Results: A total of 667 samples were examined by qPCR, of which 14 were HAstV-positive (2.1%), including HAstV-1 (n=6), MLB1 (n=6), MLB2 (n=1), and VA2 (n=1). The complete genome sequences were obtained from 11 samples. The six HAstV-1 sequences of this study had 98.2% to 99.9% nt similarities with each other and 87.6% to 98.6% with those from other regions. The four MLB1 sequences of this study had 99.1% to 99.9% nt similarities with each other and 92.2% to 99.4% with those from other regions. The VA2 sequence of this study had 96.0% to 96.3% nt similarities with those from other regions. Phylogenetic analysis based on ORF2 region showed that the local HAstV-1 sequences were most closely related to Japanese strains, and had distinct topology with phylogenies based on ORF1a and ORF1b regions. Conclusion: The complete genome sequences of 11 HAstV strains are obtained, and the VA2 complete genome is found.

Abstract
Objective: To explore the allergen map of patients with allergic diseases in northwest China, to investigate the distribution characteristics of serum specific Immunoglobulin E (sIgE) in different ages, genders, diseases and the sensitization patterns of allergens. Methods: This study is a cross-sectional study, a total of 1 161 patients with confirmed respiratory allergic diseases were selected retrospectively from outpatient or inpatient department of Gansu Provincial People's Hospital, Gansu Provincial Maternity and Child Care Hospital, General Hospital of Ningxia Medical University, Yinchuan Maternal and Child Health Care Hospital, Xijing Hospital, Air Force Military Medical University and Tumor Hospital of Inner Mongolia Autonomous Region from June 2019 to October 2022. HAIKE ALLEOS 2000 fluorescent magnetic particle chemiluminescence method was used to quantify their serum for 12 inhaled allergen-specific IgE. Chi square test or Fisher's exact test were used for comparison between count data groups (Bonferroni correction was used for further pairwise comparison in multiple groups, two-sided P<0.05/3=0.017 considered that the difference was statistically significant). Pearson correlation analysis was used for correlation of continuous numerical variables. Results: The positive detection rate of sIgE in 1 161 patients was 66.8%(776/1 161). The three highest positive rate of inhaled allergen were mugwort(599/1 161, 51.6%), French chrysanthemum(565/1 161, 48.7%) and dandelion(412/1 161, 35.5%). In different age groups, the highest positive rate of sIgE was 7-18 age group(379/513, 73.9%) while the lowest positive rate was 4-6 age group(222/370, 60.0%), the difference between groups was statistically significant(χ2=21.177, P<0.001). The sensitization peak of mugwort, French chrysanthemum, plantain, timothy, birch, dermatophagoides pteronyssinus, dermatophagoides farinae, cat epithelium, dog epithelium and German cockroach appeared in 7-18 age group. In different disease groups, the highest positive rate of sIgE was allergic rhinitis with asthma group (500/717, 69.7%) while the lowest positive rate was asthma group (76/144, 52.8%), the difference between groups was statistically significant(χ2=15.563, P<0.001). In different gender groups, the positive rate of sIgE in male (503/711, 70.7%) was higher than in female (273/450, 60.7%), the difference between groups was statistically significant(χ2=12.630, P<0.001). The multiple-sensitization rate was 86.9%(674/776) and the double-sensitization rate was 16.8%(130/776) in sIgE positive patients. Pearson correlation results showed that there was an extremely strong correlation between dandelion and French chrysanthemum(r=0.93,P<0.001). There was a strong correlation between mugwort and French chrysanthemum(r=0.64,P<0.001). In the co-sensitization analysis, the number of patients sensitized by mugwort, French chrysanthemum, dandelion, plantain and timothy accounted for 25.2%(170/674)of the total number of multiple sensitization. The number of patients sensitized by mugwort, French chrysanthemum and dandelion accounted for 58.3%(393/674)of the total number of multiple sensitization. The number of patients sensitized by mugwort, French chrysanthemum, dandelion and plantain accounted for 35.6%(240/674) of the total number of multiple sensitization. Conclusion: Mugwort, French chrysanthemum, dandelion are the major inhaled allergens in northwest China. The positive rate of sIgE was different in different ages, diseases and genders. The multiple-sensitization rate of allergen was high and there was a certain positive correlation between pollen allergen-specific IgE pairwise, suggesting that there may exist co-sensitization or cross-reactions among allergens.

Abstract
Objective: To investigate the effects of two-step retraction and en-masse retraction on tooth movement pattern of anterior teeth and posterior anchorage with clear aligners using three-dimensional finite element analysis. Methods: A finite element model of maxillary first premolar extraction case undergoing clear aligner treatment was established based on maxillofacial cone-beam CT data of a 24-year-old adult male with individual normal occlusion, who visited Department of Oral Surgery, Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine for impacted mandibular third molar in June, 2022. The initial tooth displacement of five anterior retraction protocols (two-step with canine retraction, two-step with incisor bodily retraction, two-step with incisor retraction-overtreatment, en-masse bodily retraction, and en-masse retraction-overtreatment) were evaluated. Results: Two step with canine retraction caused distal tipping of the canine and labial tipping of the incisors (0.18° for central incisor and 0.13° for lateral incisor). Two step with incisor retraction caused mesial tipping of the canine. In two step with bodily retraction protocol, uncontrolled lingual tipping was found in central incisor (0.29°) and lateral incisor (0.32°). In two-step with incisor retraction-overtreatment protocol, the movement pattern of the incisors didn't change, but the inclinations reduced to 0.21° and 0.18°. En-masse retraction caused distal tipping of the canine. In en-masse bodily retraction protocol, uncontrolled lingual tipping was also found in central incisor (0.19°) and lateral incisor (0.27°). In en-masse retraction-overtreatment protocol, the central incisor showed controlled lingual tipping (0.02°) and the lateral incisor showed palatal root movement (0.03° labial inclination). Posterior teeth exhibited mesial tipping in all five protocols. Conclusion: En-masse retraction with incisor overtreatment was beneficial to incisor torque control in clear aligner treatment.

Abstract
To ascertain the effects of Taraxacum mongolicum flavonoids (TMF) on the growth performance, digestive enzyme activity, immune indices, inflammatory response and antioxidant capacity of Channa argus, 400 C. argus with an average body weight of (8.08 ± 0.21) g were selected and divided randomly into four groups. They were fed with four experimental diets supplemented with TMF of 0 (control), 25, 50 and 100 mg/kg for 56 d, and then challenged with lipopolysaccharide (LPS) for 96 h, afterwards indices were detected. The results manifested that the addition of TMF above 50 mg/kg in the dietary could significantly improve the final body weight, WGR, SGR and PER of C. argus, while decreased FCR (P < 0.05). Similarly, the 50 mg/kg group had the highest activity of digestive enzymes (protease, lipase, amylase) in intestine and hepatopancreas, which were notably higher than those in the control group (P < 0.05). Nevertheless, 100 mg/kg group could effectively inhibit the liver and gut injury caused by LPS and reduce the contents of ALT and AST, LPS and LBP in serum. In the immune (LY, AKP, ACP, IgM, C3) and antioxidant (T-AOC, SOD, CAT, GSH-PX, GR, ASA, MDA) systems, 100 mg/kg groups were the optimal group, which were remarkably higher than those of the control group (P < 0.05). Additionally, the expression of genes revealed that 100 mg/kg group could noteworthy restrain the expression of pro-inflammatory factors (tnf-α, il-1β, il-8) and pro-apoptosis (cas-3,8,9, p53, bax, bcl-2) related genes, up-regulate the expression of anti-inflammatory (il-10, tgf-β) factors, antioxidant-related (nrf2, gpx, gst, cat) genes and heat shock proteins (hsp70, hsp90). Simultaneously, the survival rate of C. argus in the 100 mg/kg TMF-supplemented group was the highest after LPS challenge. Our results elucidate that dietary supplementation TMF protects C. argus from LPS-induced inflammatory injury, to ameliorate digestion, immune response, antioxidant status and apoptosis, implying that TMF could be regarded as an anti-inflammatory and antioxidant agent adding to aquatic animal feed.

Abstract
Objective: To observe the toxic effects of different doses of baicalin on liver and kidney of rats after different time administration, and provide experimental reference for the safety of clinical medication. Methods: In April 2019, 42 Wistar male rats were randomly divided into a control group (0.9% sodium chloride solution) and baicalin administration groups (100, 200 mg/kg) , 14 rats in each group, and one was given by oral gavage. 7 times/d, 6 times/week, 7 rats in each group were sacrificed 28 and 56 days after the administration. The wet weights of liver and kidney were weighed and the organ coefficients were calculated. The hematoxylin-eosin (HE) staining was used to detect the histomorphological changes. And the levels of serum alanine aminotransferase (ALT) , aspartate aminotransferase (AST) , alkaline phosphatase (ALP) , blood urea nitrogen (BUN) and creatinine (CRE) were detected. Results: After 56 days of administration in baicalin 200 mg/kg rats, the body weight and kidney coefficient were lower than those of the control group. Histopathology showed that glomerular atrophy became smaller, renal tubules were significantly atrophied, and epithelial cell necrosis occurred. No obvious abnormalities in liver was observed. After 56 days of administration in baicalin 200 mg/kg rats, the levels of BUN and CRE in the serum were higher than those of the control group, and the differences were statistically significant (P<0.05) . There were no obvious abnormalities in the baicalin 100 mg/kg group and the 28 d of administration in baicalin 200 mg/kg group. Conclusion: Under the conditions of this test, baicalin has certain renal toxicity in male rats.

Abstract
Objective: To examine the correlations of C-reactive protein (CRP)/albumin ratio (CAR) with the postoperative complications of patients with colorectal cancer. Methods: The clinic data of 312 patients undergoing elective surgery for colorectal cancer in Hainan Hospital of People's Liberation Army General Hospital between January 2013 and July 2018 was analyzed retrospectively. There were 188 males and 124 females, aged (61.0±12.9) years (range: 21 to 86 years). Logistic analysis was used to identify relative factors for postoperative complications. Receiver operating characteristic curves were developed to examine the cutoff values and compare diagnostic accuracy of the CAR and CRP levels. Results: Postoperative complications occured in 28.5% (89/312) cases. Hemoglobin on postoperative day(POD) 3 (OR=0.977, 95% CI: 0.957 to 0.998, P=0.034), preoperative CRP (OR=1.209, 95% CI: 1.055 to 1.386, P=0.006) and CAR on POD 3 (OR=0.033, 95% CI: 0.016 to 0.067, P<0.01) were found to be significant independent relative factors for postoperative complications. The cutoff point of CAR on POD 3 was 0.325, patients with CAR≥0.325 were found to have more postoperative complications than those with CAR<0.325. The area under the curve of CAR on POD 3 and preoperative CRP were 0.872, 0.626, respectively. The positive predictive value of CAR on POD 3 was higher than that of preoperative CRP (79.9% vs. 55.1%). Conclusions: CAR is closely related to the occurrence of postoperative complications in colorectal surgery. Patients with CAR≥0.325 on POD 3 has higher incidence of postoperative complications.

Abstract
The data were drawn from injury hospitalization surveillance system in Shandong province. From 2012 to 2018, 164 cases of acute occupational poisoning were reported from five surveillance counties (cities, districts), accounting for 6.11% (164/2 683) of total accidental poisoning cases. The annual average reported incidence of acute occupational poisoning hospitalization was 1.15/100 000. The number of male cases was 3.3 times that of females (126 vs 38). The poisoning cases mainly occurred between January to May in a year and 5-7 AM within a day. Those cases were mainly caused by irritating gases (92 cases, 56.10%) and asphyxiating gases (53 cases, 32.32%), of which chlorine (71 cases) and carbon monoxide (50 cases) were the main reasons. The average hospitalization medical cost of acute occupational poisoning cases was 7 278.81 RMB per case.

Abstract
Objective: To observe and compare the effects of two standards on the overweight trend in urban Shanghai infants and young children. Methods: A cluster randomized controlled trial was conducted in 19 communities in two districts of Shanghai, and the subjects (n=15 019) were divided into S-group and W-group by sealed envelope randomization. The subjects were newborns born between November 2013 and December 2014. The 2005 Shanghai growth standard was applied in the S-group and the 2006 WHO growth standard was used in the W-group. At each follow-up time point age of 1, 2, 4, 6, 9, 12 and 18 months, the outpatient physician assessed the length and weight of the infants according to the standard adopted by each group and provided feeding guidance. The weight-for-age Z scores (WAZ), length-for-age Z scores (LAZ) and weight-for-length Z scores (WLZ) were calculated according to the WHO standard. Weight, length, WAZ, LAZ, WLZ and overweight ratio (WLZ≥2) were compared between the two groups using t test, Wilcoxon test and χ(2) test. Results: A total of 6 509 infants (3 391 were boys, 3 118 were girls) were in the W-group, and 8 510 infants (4 374 were boys, 4 136 were girls) were in the S-group. Among the boys, the weight values at the age of 4, 6, 9, 12, 18 months in the W-group were all lower than those in the S-group ((7.5±0.8) vs. (7.7±0.8) kg, (8.6±0.8) vs. (8.7±0.8) kg, (9.6±0.9) vs. (9.7±0.9) kg, (10.4±1.0) vs. (10.5±1.0) kg, (11.5±1.1) vs.(11.7±1.1) kg; t=4.329, 2.422, 3.739, 2.451, 2.736; P<0.01, 0.015,<0.01, 0.014, 0.009). The length had no significant difference between two groups at all months of age(all P>0.05). The overweight ratio in the W-group was lower than that in the S-group at the age of 9, 12, 18 months(3.3% (71/2 170) vs. 4.9% (143/2 927), 2.5% (51/2 037) vs. 4.5% (126/2 818), 0.8% (7/832) vs. 3.1% (39/1 266); χ(2)=6.520, 14.209, 12.350; P=0.011,<0.01,<0.01).Among the girls, except at the age of 2 months (W-group (5.6±0.6) vs. S-group (5.7±0.6), t=2.935, P=0.003), weight values had no significant difference between the two groups at other age months (all P>0.05).The length in the W-group was higher than that in the S-group at 12 and 18 months of age ((75.6±2.4) vs.(75.5±2.3)cm, (82.4±2.9) vs.(82.2±2.7) cm; t=2.351, 2.197; P=0.019, 0.028). The ratio of overweight in the W-group was lower than that of S-group at the age of 12 and 18 months (1.8% (33/1 871) vs.3.0% (80/2 658), 0.6% (5/790) vs.1.7% (20/1 178); χ(2)=6.764,4.276; P=0.009, 0.039). Conclusions: The application of WHO growth standard can help to reduce the weight gain rate of boys, promote the linear growth of girls, and thus alleviate the overweight trend of infants within 18 months. It suggested that 2006 WHO growth standard should be applied to infants within 1 year of age in Shanghai.

Abstract
Objective: To compare the clinicopathological features and prognosis of pancreatic cystic neoplasms (PCN) between male and female patients. Methods: A total of 325 patients with histological confirmed PCN from January 2010 to October 2015 were enrolled. The clinicopathological features, laboratory examination, imaging features, treatment and prognosis were analyzed. Results: Of the 325 patients diagnosed as PCN, 104 were male and 221 were female. The average age of male patients was significantly higher than that of female patients (55.0±12.7 vs 47.9±13.4 years, P<0.001), however, the average tumor size of male patients was smaller than that of female patients (3.9±2.7 vs 4.9±3.0 cm, P=0.004). The location of PCN in male patients was predominantly located at pancreatic head and neck, and majority of male patients were mucinous cystic neoplasms. 1-year, 3-year and 5-year survival rates of patients with PCN were 98.5%, 92.6%, and 87.5%, respectively. 1-year, 3-year and 5-year survival rates of male patients were 97.8%, 84.9%, and 77.8%, however, those of female patients were 98.8%, 96.5%, and 92.2%, respectively. Female patients had better prognosis than male patients (χ2=5.543, P=0.019). Elevated CA19-9 (χ2=3.843, P=0.050), perineuronal invasion (χ2=6.250, P=0.012) and lymph node metastasis (χ2=4.529, P=0.033) were important prognostic factors for malignant mucinous cystic neoplasm. Conclusions: Male patients had low incidence of PCN, and were more common for mucinous cystic neoplasm. The long-term outcome of malignant PCN was poor. Even with complete resection, male patients still had worse prognosis. Close follow-up is recommended especially for male patients.

Abstract
OBJECTIVE To describe the clinicopathological characteristics and prognostic factors of mucinous cystic neoplasm(MCN). METHODS One hundred and thirteen patients with MCN comfirmed by histological examination admitted in People's Liberation Army General Hospital from January 1994 to June 2015 were analyzed, including 21 male and 92 female patients with mean age of (50.2±14.5) years. Forty-eight patients had incidental discovery of their cystic neoplasm for another reason, 65 patients were symptomatic, and abdominal pain or distension was main clinical symptom. Among 113 patients with MCN, 75 cases were MCN with dysplasia, and 38 cases were MCN with invasive carcinoma. Wilcoxon test and χ(2) test, et al were used to analyzed the data, respectively. RESULTS MCN was mostly located in body and tail of pancreas.Sex, mean age, clinical symptom, tumor size, and CA19-9 showed significant difference between MCN with dysplasia and MCN with invasive carcinoma (all P<0.05). The presence of a solid component (χ(2)=32.460, P=0.000)and main pancreatic duct dilation(χ(2)= 5.729, P=0.022) were significantly associated with malignancy. Fifty-eight patients with dysplasia were followed up, only one patient occurred tumor recurrence. Thirty-one patients with malignancy were followed up, among which there were 22 patients dead, 1-, 3-, 5-year survival of MCN with malignancy was 76.9%, 56.5%, 36.6%, respectively. Lymphatic metastasis and tumor recurrence were important prognostic factors of MCN with malignancy(both P<0.05). CONCLUSIONS MCN is most affected by old female with no specific symptom, most tumors are located at the body and tail of the pancreas.MCN with dysplasia have excellent prognosis underwent surgery. Even with complete resection, the long-term survival of MCN with malignancy is not satisfied.

Abstract
BACKGROUND Cancer-induced bone pain remains a clinical challenge due to the poor understanding of the mechanisms. Recent study revealed extracellular adenosine triphosphate (ATP) and P2X receptors may be implicated in nociceptive signalling under cancer pain state. Therefore, here we investigated the potential role of P2X(3) receptor in a rat model of bone cancer pain. METHODS Walker 256 tumour cells were inoculated into the left tibia of Wistar rats. The model was verified by X-ray imaging, pathology and behaviour examinations. The expression of P2X(3) receptors in dorsal root ganglia (DRG) was examined. Functional significance of altered P2X(3) receptors was investigated by measuring influx upon α,β-meATP stimulation in acutely dissociated DRG neurons. Moreover, A-317491, an antagonist of P2X(3) receptors, was administrated intrathecally or locally to evaluate its analgesia effect in the cancer pain animals. RESULTS The P2X(3) receptor was up-regulated for about 50% in DRG neurons in rats with bone cancer at both protein and mRNA levels and correlated with the pain behaviour in bone cancer rats. A 51.9% increase of α,β-me ATP (10 μM, for 4 s) evoked transient response currents and a higher percentage of neurons responsive to the application of α,β-me ATP was detected in bone cancer rats. Intrathecal or local injection of A-317491 significantly attenuated pain behaviour induced by bone cancer. CONCLUSIONS These results suggest that the P2X(3) receptor is functionally up-regulated in DRG in cancer rats. P2X(3) receptor is a promising target for therapeutic intervention in cancer patients for pain management.

Abstract
Electroacupuncture (EA) has been successfully used to alleviate pain produced by various noxious stimulus. Cholecystokinin-8 (CCK-8) is a neuropeptide involved in the mediation of pain. We have previously shown that CCK-8 could antagonize the analgesic effects of EA on pain-excited neurons (PENs) and pain-inhibited neurons (PINs) in the nucleus parafascicularis (nPf). However, its mechanism of action is not clear. In the present study, we applied behavioral and neuroelectrophysiological methods to determine whether the mechanisms of CCK-8 antagonism to EA analgesia are mediated through the CCK-A receptors of PENs and PINs in the nPf of rats. We found that focusing radiant heat on the tail of rats caused a simultaneous increase in the evoked discharge of PENs or a decrease in the evoked discharge of PINs in the nPf and the tail-flick reflex. This showed that radiant heat could induce pain. EA stimulation at the bilateral ST 36 acupoints in rats for 15 min resulted in an inhibition of the electrical activity of PEN, potentiation of the electrical activity of PIN, and prolongation in tail-flick latency (TFL), i.e. EA stimulation produced an analgesic effect. The analgesic effect of EA was antagonized when CCK-8 was injected into the intracerebral ventricle of rats. The antagonistic effect of CCK-8 on EA analgesia was reversed by an injection of CCK-A receptor antagonist L-364,718 (100 ng/μl) into the nPf of rats. Our results suggest that the pain-related neurons in the nPf have an important role in mediating EA analgesia. L-364,718 potentiates EA analgesia through the CCK-A receptor of PENs and PINs in the nPf.

Abstract
This study assessed the effect of inhibition of the central nucleus of the amygdala (CeA) and drug experience on brain regions underlying footshock-induced reinstatement of morphine-seeking behaviour in rats. The difference in time spent in two chambers of a place-preference apparatus was used to measure morphine-conditioned place preference. Fos was measured as a marker of neuronal activation in the ventral bed nucleus of the stria terminalis (BNSTv) and ventral tegmental area (VTA). Footshock was found to enhance Fos expression in the BNSTv regardless of drug experience. In the VTA, morphine and footshock had an interactive effect on the increase in Fos expression. Inhibition of the CeA decreased Fos expression in the BNSTv regardless of drug experience, whereas in the VTA this effect only occurred in morphine-treated rats. These results suggest that drug experience has no differential effect on the BNSTv however morphine produces footshock sensitization in the VTA. CeA inhibition modulates the footshock-induced activity of these regions of the brain and attenuates reinstatement of drug seeking behaviour.

Abstract
PURPOSE To investigate the effect of Calorie Restriction (CR) on learning and memory ability of early aged rats. METHODS 18-month rats were subjected to restricted intake by 60% comparing with that of rats fed ad libitum (AL) for 6 months. We compared the overall health status, including survival rate and locomotor activity by open-field test. We examined the spatial cognition ability of the rats by Morris Water Maze. RESULTS Our results showed that CR rats had higher survival rate and spontaneous locomotor activity compared with AL rats. CR rats slowed the inability of spatial learning and reference memory. CONCLUSION These findings demonstrated that CR in early old rats delayed the declination of spatial cognition.

Abstract
AIM To study the antagonism of sincalide to the effect of morphine and its mechanism. METHODS The electrophysiologic and mechanic activities of rat jejunum in vitro were recorded. RESULTS Acetylcholine (ACh, 150 nmol.L-1) increased the spike potential amplitude (SPA) and the number (SPN) of rat jejunum in vitro, followed by an increase of jejunal contraction amplitudes (CA), showing a positive correlation. Morphine 330 nmol.L-1 inhibited the potentiation of ACh, showing a negative correlation. Sincalide 0.7 nmol.L-1 antagonized the effects of morphine, i.e., the SPA and SPN were increased again, followed by an increase of CA. CCK-A receptor antagonist devazepide (10 nmol.L-1) reversed the antagonism of sincalide to the effect of morphine. CONCLUSION Sincalide antagonized the effect of morphine which inhibited the potentiation of ACh on jejunal activities in vitro. The antagonistic effect of sincalide on morphine was mainly mediated by CCK-A receptor.

Abstract
In the present investigation, antagonistic action of cholecystokinin octapeptide (CCK-8) against morphine on the electrical and contractile activity of rat jejunum in vitro was studied. The results showed that the potentiation of acetylcholine (ACh) on both the burst of spike and the contractility were inhibited by morphine, which could be completely antagonized by CCK-8. The CCK-8 effect, again, could be suppressed by CCK-A receptor antagonist devazepide (10 nmol/L), but partially by CCK-B receptor antagonist L-365, 260 at 10 nmol/L or completely at concentration of 30 nmol/L. The above results demonstrated that the antagonism of CCK-8 on morphine was mediated by both CCK-A and CCK-B receptors.

Abstract
We studied the T lymphocyte transformation and IL-2's functions induced by anti-CD3 mAb in 42 cases of CPHD. The T lymphocyte transformation, activity of IL-2 and expression of IL-2R were determined by 3H-TDR incorporation, bioassay and immunoabsorption methods. The results showed that PBL transformation and activity of IL-2 were decreased in the patients of acute exacerbation stage more than those in controls and remission stage (P < 0.05 or P < 0.01); activity of IL-2 in the patients of remission stage was close to that in controls (P > 0.05), but PBL transformation was still less than that in controls (P < 0.01); Expression of IL-1R were increased in the patients more than in controls (P < 0.01). G.I of anti-CD3mAb and PHA stimulating PBL proliferation showed positive correlation (P < 0.01), activity of IL-2 and expression of IL-2R were not correlated (P > 0.05). The results showed that extrinsic IL-2 could enhance PBL proliferations induced by anti-CD3mAb, especially in CPHD patients.

Abstract
In addition to method of ACTH RIA, a rat pituitary cell perfusion system was developed for the assessment of pituitary cells in stimulating and inhibiting ACTH secretion induced by some substances. Hypothalamic extract stimulated the ACTH secretion in a dose-dependent manner. AVP, cAMP, Ca2+, K+, noradrenaline, metoclopramide and haloperidol also had some stimulating effect. Dexamethasone and dopamine inhibited the basal ACTH secretion of pituitary cell and antagonized the effect of the various stimulating substances. Cyproheptadine could antagonize the effect of some of the stimulating substances while GABA had no marked inhibiting effect.

Abstract
The clinical implications of nuclear T3R alterations of circulating lymphocytes in hyperthyroidism, hypothyroidism and nonthyroidal diseases were investigated. Nuclear T3R in lymphocytes was determined by radio-ligand binding analysis. The results showed that in hyper- and hypothyroid patients the nuclear affinity (Ka) for T3 was similar to that of normal subjects. In hyperthyroidism nuclear T3 maximal binding capacity (MBC) was unaltered, whereas in hypothyroidism the MBC was significantly increased. In the patients with diabetes mellitus, chronic renal failure and hepatic cirrhosis, the nuclear T3R MBC of lymphocytes was about 1.5-1.6 times of the normal controls. It was concluded that there existed hormonal regulation of nuclear T3R, and up-regulation was seen in hypothyroidism and low T3 syndrome.

Abstract
When acute morphine-tolerated rat was administered by ip morphine (10 mg/kg) which was effective before the acute tolerance to morphine, both the inhibitory effect of morphine on the electric discharges of pain-excitation neurons (PEN) in nucleus parafascicularis (PF) and the excitatory effect of morphine on the electric activities of pain-inhibition neurons (PIN) were simultaneously weakened, or even vanished. If a large dose of morphine (20 mg) was given ip, the modulating action of morphine on simultaneous electric discharges of PEN and PIN reappeared. It is obvious that the phenomenon of acute morphine tolerance and the antagonism to morphine tolerance can be explicitly expressed on the level of central neurons.

Abstract
This study reviews the diagnosis and treatment of 15 patients with malignant pheochromocytoma (MP) between 1958 and 1986 in Shanghai Rui-jin Hospital. The main clinical features consisted of sustained elevation of arterial blood pressure, obviously increased catecholamine secretion and a sustained positive phentolamine test. Out of 15 patients only seven survived, two of whom suffered from paraplegia due to metastatic cordal compression. Compared with some earlier results, the prognosis was unsatisfactory. There were several factors which may have been responsible: (1) late diagnosis; (2) incomplete operation, and (3) no regular post-operative assessment of urinary biochemical changes. Because MP is a tumour with a low degree of malignancy, noting the above three factors and using 131I-MIBG to obtain accurate diagnosis and effective treatment enables a better prognosis of this disease.

Abstract
The effects of edible black tree fungus (BFF) compared with aspirin on serum lipid level and experimental atherosclerosis and thrombosis in rabbits were studied. The results showed that total serum cholesterol and B-lipoprotein of the BTF group were significantly decreased (P less than 0.01) than the aspirin group and the group with neither BTF nor aspirin. There were less aortic atherosclerotic plaque and intramyocardial arterial lumen stenosis in the BTF group. The development of thrombus and platelet aggregation and thromboxane TXB2 level were inhibited both in the BTF and aspirin group (P less than 0.01). These findings indicate BTF may be used as a healthy food in preventing atherosclerosis and coronary heart disease, but its mechanism requires further investigation.
