Objective:Through comprehensive analysis of symptoms and signs, biochemistry, imaging, and dynamic tests, to explore the diagnosis and differential diagnosis of thyrotropin-secreting pituitary adenoma(TSH adenoma) and syndrome of resistance to thyroid hormone(RTH).Methods:A retrospective analysis was conducted on clinical data from 14 patients who visited the First Affiliated Hospital of Zhengzhou University from July 2016 to September 2022, exhibiting elevated levels of free thyroxine(FT4) and free triiodothyronine(FT3) in the presence of increased TSH.Results:There were 7 cases of TSH adenoma and 7 cases of RTH, with the average age of diagnosis at 40.0 years and 26.6 years, respectively. Thirteen patients showed thyrotoxicosis or occasional palpitation, some with pituitary occupancy manifestations or abnormal growth and development; One patient presented with neck thickening. Sex hormone binding globulin was elevated in 3 cases of TSH adenoma. Pituitary magnetic resonance imaging showed that all 7 cases of TSH adenoma were macroadenomas and 1 case of RTH was microadenoma. The octreotide suppression test in 13 patients was inhibited, but there was a significant difference in the inhibition rate of 24 h/2 h TSH inhibition rate of TSH adenoma and RTH, ranging from 46.6% to 83.9% and 4.6% to 28.8% respectively. Six cases of RTH had thyroid hormone receptor β mutation.Conclusion:Syndrome of inappropriate secretion of thyrotropin is a rare condition, mainly including TSH adenoma and RTH. The diagnosis and differentiation of the two conditions require comprehensive assessment incorporating family history, symptoms and signs, laboratory tests, dynamic test, and genetic test. Among these, the 24 h/2 h TSH inhibition rate of octreotide suppression test can effectively distinguish TSH adenoma from RTH.

Objective:To observe the effects of continuous light exposure on skeletal muscle fiber type transformation and lipid metabolism, and to explore its internal relationship.Methods:Mice were randomly divided into normal light group and 24-hour continuous light group by random number table. The serum and skeletal muscle lipid content and urine 6-sulfatoxymelatonin(6-SML)level were detected by ELISA. The expression of circadian clock and lipid metabolism related genes mRNA were observed by realtime PCR. The muscle fiber type and lipid deposition were evaluated by tissue immunofluorescence as well as oil red O staining.Results:Compared with the normal light group, the level of 6-SML in urine at night decreased( P<0.05), and the expression level and rhythm of brain and muscle ARNT-like protein 1(Bmal1), circadian locomotor output cycles protein kaput(Clock), and period 2(Per2)mRNA in the skeletal muscle changed in continuous light group. In addition, the body weight, blood lipid, free fatty acid, and triglyceride contents of skeletal muscle in continuous light group increased significantly( P<0.05 or P<0.01), the expression of carnitine palmitoyltransferase 1b (Cpt1b)mRNA, the key enzyme of fatty acid oxidation, decreased significantly( P<0.05), while the expression of stearoyl-CoA desaturase(Scd1)mRNA, a lipid synthesis related gene, increased significantly( P<0.01). Further immunofluorescence analysis showed that the proportion of slow muscle fibers decreased and that of fast muscle fibers increased in continuous light group(both P<0.05). Conclusion:The process of ectopic deposition of lipid in skeletal muscle in mice induced by continuous light exposure may be related to the remodeling of skeletal muscle fibers.

Objective To investigate the changes in serum procalcitonin (PCT) in patients with severe pneumonia, and to analyze its value on evaluating the clinical outcome of patients with severe pneumonia. Methods A total of 58 patients with severe pneumonia aged over 18 years, and admitted to intensive care unit (ICU) of Zhuozhou City Hospital of Hebei Province from January 2017 to July 2018 were enrolled. The patients were divided into recovery group (the symptoms and signs of pneumonia disappeared or improved, and the X-ray chest films improved or did not make significant progress) and deterioration group (the symptoms and signs of pneumonia persisted or progressed, while X-ray chest radiography progressed, as well as serious complications such as involvement of other organ functions due to deterioration of pulmonary infection or septic shock) according to the therapeutic outcome. The serum PCT levels at 1, 3, 5, 7, 9 days after severe pneumonia diagnosed were recorded, and procalcitonin clearance rate (PCTc) was calculated. The acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score was estimated within 24 hours when severe pneumonia was diagnosed. Receiver operating characteristic (ROC) curve was drawn, and the area under ROC curve (AUC) was calculated to analyze the value of PCTc on evaluating the clinical outcome of patients with severe pneumonia. Results Among 58 patients, 33 (56.9%) had better outcome after active treatment (recovery group), and 25 (44.1%) had worse condition (deterioration group). There was no significant difference in PCT level at 1 day or 3 days between the recovery group and the deterioration group [μg/L: 5.05 (3.89, 7.61) vs. 5.29 (4.15, 7.46) at 1 day, 4.59 (4.02, 6.90) vs. 5.70 (4.59, 7.28) at 3 days, both P > 0.05]. With the prolongation of treatment time, serum PCT level was gradually decreased in the recovery group, while remained at higher level in the deterioration group, which was significantly lowered at 5, 7, 9 days in the recovery group as compared with that in the deterioration group [μg/L:2.92 (2.09, 3.42) vs. 6.09 (3.24, 7.96) at 5 days, 1.94 (1.50, 2.07) vs. 7.65 (5.60, 10.52) at 7 days, 1.37 (0.91, 1.74) vs. 8.96 (6.09, 10.87) at 9 days, all P < 0.01]. PCTc at 3, 5, 7, 9 days in the recovery group were significantly higher than those in the deterioration group [15.10 (-17.80, 32.10)% vs. -1.53 (-20.80, 11.48)% at 3 days, 47.50 (30.25, 60.34)% vs. 6.25 (-14.58, 29.05)% at 5 days, 76.44 (53.18, 77.92)% vs. -11.20 (-66.75, -1.38)% at 7 days, 80.01 (59.86, 88.27)% vs. -38.15 (-99.38, -2.81)% at 9 days, all P < 0.05]. ROC curve analysis showed that PCTc at 3, 5, 7 and 9 days were valuable for evaluating the clinical outcome of patients with severe pneumonia, and 9-day PCTc had the greatest value, the AUC was 0.978 [95% confidence interval (95%CI) = 0.945-1.000, P = 0.000], which was higher than APACHEⅡ(AUC = 0.442, 95%CI = 0.280-0.610, P = 0.392); when the best cut-off value of 9-day PCTc was 93.00%, its sensitivity was 99.0%, and specificity was 87.3%. Conclusions The PCT level of patients with severe pneumonia remained at a high level, which was related with the deterioration of the disease. PCTc, as an index to evaluate the clinical outcome of patients with severe pneumonia, has good application value.

As a pandemic metabolic disease, obesity has become a worldwide problem, which endangering human health. The change in body weight reflects the energy imbalance. And the homeostasis regulation of the central and peripheral melanocortin system may maintain the energy balance and then affect the body weight. Recent studies have found that melanocortin receptor-4 ( MC4R) plays an important role in energy homeostasis and body weight changes, but its specific mechanism needs further elucidation. In this paper, we reviewed the research progress of MC4R in body weight and energy regulation, so as to provide a theoretical basis for further exploring the potential role of MC4R in improving energy metabolism imbalance and obesity.

Objective? To investigate the awareness of nutrition knowledge among colorectal cancer patients and to explore the effects of nutrition management on patients' nutrition. Methods? From January 2016 to December 2016, we selected 80 colorectal cancer inpatients of internal and surgical department of oncology in Xuzhou Central Hospital as subjects by convenience sampling. The self-designed nutritional knowledge questionnaire for colorectal cancer patients was used to investigate their awareness of nutrition knowledge. All of the patients were divided into observation group (n=40) and control group (n=40) with the random number table. Control group received routine nutrition guidance. Observation group carried out whole-course nutrition management. And then, the nutrition of patients in two groups was compared before and after intervention. Results? The awareness rate on nutrition knowledge of colorectal cancer patients was 60.0% (48/80). There were statistical differences in the awareness rate on nutrition knowledge among patients with different ages, education, family history of colorectal cancer, whether it was the first case and whether they received nutrition education (P＜ 0.05). Patients' total serum protein, serum albumin and hemoglobin of observation group were higher than those of control group; the score of nutrition risk screening-2002 (NRS 2002) of observation group was higher than that of control group; the differences were all statistical (P＜0.05). Conclusions? The awareness rate on nutrition knowledge of colorectal cancer patients is low. Strengthening nutrition management for patients will contribute to improving patients' nutrition and nutrition risk.

Objective To investigate the expression alteration and significance of long non-coding RNA (lncRNA)by GWAS(Genome-wide association study)between Esophageal squamous cell carcinoma(ESCC)and its adjacent normal esophageal tissues. Methods lncRNA and mRNA differential expression in 6 pairs of ESCC and matched non-cancerous tissues were screened by microarray assay. The target genes were predicted. Finally , GO(Gene Ontology)and Pathway analysis was used for the further research of lncRNA. Results A total of 680 lncRNA and 1472mRNA were differentially expressed at more than two-fold change(P ≤ 0.05,with 161lncRNA and 653mRNA up-regulated,519lncRNA and 819mRNA down-regulated between ESCC and its adjacent normal esophageal tissues. Gene ontology and pathway analysis results suggested that the differentially expressed genes were involved in 11 pathways.Theyare potentially associated with esophageal squamous cell carcinoma ,including post-translational protein modification ,mucin type O-Glycan biosynthesis and sphingolipid metabolism pathways , which mainly related to the changes of molecular function ,cellular components and biological processes. Through cis and trans analysis,a total of 15 differentially expressed lncRNA had cis-and/or trans-regulated target genes in the database,with 13 lncRNA had cis-regulated target genes,3 lncRNA had trans-regulated target genes,and 1 lncRNA had both cis- and trans-regulated target genes. Conclusion Compared with adjacent normal tissues ,a large number of lncRNA were expressed differentially in ESCC in Xinjiang Han people.Aberrantly expressed lncRNA may play important roles in ESCC development and progression through some signaling pathways ,which are of great significance for further search of new targets for the diagnosis and treatment of ESCC.
