Aim To explore the effects of heat stress on TNF-?-induced fever and the content of cAMP in rat hypothalamus. Methods ①We examined the peak time of HSP70 expression in hypothalamus after heat stress; ②We studied the change of TNF-?-induced fever and the content of cAMP in hypothalamus after heat stress. Result The maximum expression of HSP70 in hypothalamus was attained at 12 h after heat stress. Heat stress limited TNF-?-induced fever and decreased the content of cAMP in hypothalamus. Conclusion Heat stress can inhibit TNF-?-induced fever in rats, and this effect may be related with the inhibition of cAMP synthesis induced by high expression HSP70 in hypothalamus.

Abstract: Objective　To understand the contamination status, drug resistance, virulence gene carrying status, and molecular typing characteristics of Vibrio parahaemolyticus (VP) in aquatic products sold in Nanchang City. Methods　A total of 170 commercial crayfishes, freshwater fish frogs and related smears samples were collected from various farmers' markets in Nanchang from March to September 2021. The strains of V. parahaemolyticus were detected and isolated from the samples. Antibiotic resistance test, virulence gene test, and pulsed-field gel electrophoresis (PFGE) molecular typing analysis were carried out. Results　Among the collected samples, V.parahaemolyticus was only isolated from crayfish and crayfish smear samples, with a total of 35 strains of VP isolated. No V.parahaemolyticus strain was isolated from other freshwater fish, frogs, and their smear samples. Among the 17 common antibiotics tested, only two trains showed resistance to ampicillin, and one strain to streptomycin, , and all were sensitive to other antibiotics; all 35 strains of V. parahaemolyticus carried the gene, but only one strain carried the heat-resistant related hemolysin gene trh, and no direct heat-resistant hemolysin gene tdh positive strain was found; PFGE pattern clustering showed that there was no strain with the same PFGE pattern, and there was no obvious dominant cluster among these strains, and their genetic relationship was relatively distant. Conclusions　The contamination of V. parahaemolyticus in small and medium-sized crayfish sold in the market in Nanchang City is relatively serious. The V. parahaemolyticus isolates in these polluted crayfish generally do not carry key virulence genes such as tdh, are sensitive to common antibiotics, and only have low-level resistance to ampicillin and streptomycin. PFGE pattern clustering showed that V. parahaemolyticus does not have no obvious dominant cluster, and these strains have rich genetic diversity, indicating that they may have different sources.

ObjectiveTo investigate the pathologic characteristics of the sural nerve in amyotrophic lateral sclerosis. MethodsClinical, electrophysiologic, laboratory data and sural nerve biopsy of 11 patients were reviewed. The clinical and laboratory data were compatible with the diagnosis of ALS. The sural nerve was removed and immediately fixed in 10% formalin and phosphate-buffered 2.5% glutaraldehyde and processed according to the procedure used in our laboratory for light and ultrastructural examination.Results4 groups were distinguished based on pathologic changes: normal; with mild axon degeneration and demyelination; with mild loss of the myelinated nerve, axon degeneration and demyelination; with severe loss of the myelinated nerve, axon degeneration and demyelination.ConclusionPredominantly axonal neuropathies are common and occur early in ALS. Axon degeneration of the nerve fibers is predominant, and demyelination also can be performed in patients with ALS.

Objective To investigate the expression of the preferentially expressed antigen of melanoma (PRAME) gene in acute myeloid leukemia (AML),and to evaluate its applicability in monitoring minimal residual disease (MRD).Methods Bone marrow specimens were collected from 63 cases of de-novo AML,while 34 samples from 11 patients were tracked for 28 months.The level of PRAME mRNA was measured by real time RT-PCR.Results The PRAME gene expressed in 52.4 ％ (33/63) of de-novo patients,and the positive rate was highest in M3 than that in other subtypes of AML.The expression of PRAME became negative after treatment and increased in the following months before morphology relapse.Conclusion The PRAME gene is highly expressed in AML and could be a useful marker to monitor MRD.

AIM:ToinvestigatetheexpressionofFoxp3+regulatoryTcells(Foxp3+Tregs)andprogrammed death receptor 1 (PD1) in gastric cancer tissues and their association with clinicopathological factors and prognosis of the patients.The correlation between the 2 molecules was also analyzed at the same time.METHODS: The tumor sections from 111 gastric cancer patients were stained for Foxp3 and PD1 by the method of immunohistochemistry.The associations of the expression levels of these 2 molecules with clinicopathological factors involved in the disease progression and progno-sis were statistically analyzed .The relationship of their expression was detected.RESULTS:Foxp3 +Tregs and PD1 were expressed in the gastric cancer tissues, and PD1 was expressed in the tumor infiltrating lymphocytes ( TILs) .The expres-sion of Foxp3 and PD1 was correlated with lymph node metastasis, clinicopathological stage and prognosis of gastric cancer patients.The expression of these 2 determinants in the patients with lymph node metastasis and an advanced clinicopatho-logical stage was distinctly higher ( P<0.05 ) .The patients with positive expression of the 2 indexes presented a lower overall survival rate and worse prognosis (P<0.05).A significantly positive correlation between the infiltration of Foxp3 +Tregs and the expression of PD1+TILs was also observed (P<0.01).CONCLUSION:Foxp3 +Tregs and PD1 +TILs co-infiltrate in the gastric cancer tissues, which can be used as biological markers to predict the disease progression and prog-nosis.
