Desmoplastic small round cell tumors (DSRCT) are highly aggressive tumors typically involving the serosal surfaces of the peritoneum. Patients often present with abdominal pain, an abdominal mass, ascites or signs of intestinal obstruction. Cytogenetic and molecular studies have identified a characteristic t(11;22)(p13;q12) translocation within the tumor cells. The fused gene product apparently aligns the NH2-terminal domain (NTD) of the EWS gene to the zinc finger DNA-binding domain of the WT1 gene. This product could lead to loss of the tumor suppressor effect of the WT1 gene as well as to an increase in EWS driven expression of growth factors normally repressed by WT1. We investigated this latter possibility by performing immunohistochemical studies on formalin fixed tissue from 10 cases of DSRCT and five Wilms' tumors using-antibodies to insulin-like growth factor (IGF)-II, the latency associated peptide of transforming growth factor (TGF)-beta 1, platelet-derived growth factor (PDGF)-AB chain and PDGF-alpha receptor, respectively. In general, tumor cells were strongly positive for these growth factors in DSRCT, while stromal cells were negative for IGF-II and positive for the other growth factors in parallel with the tumor cells. Wilms' tumor cells were essentially negative for PDGF-AB chains, but positive for IGF-II, and the latency associated peptide of TGF-beta 1 and variably positive for PDGF-alpha receptor. These findings support the proposed molecular mechanism of tumorigenesis for DSRCT and may help explain this tumor's poor prognosis.

A 36-year-old woman presented with right upper quadrant abdominal pain, weight loss and attacks of severe sweating. She was known to have a chronic hepatitis B infection. A large hepatocellular carcinoma was diagnosed complicated by recurrent episodes of hypoglycaemia. Serum insulin, insulin-like growth factor (IGF-I) and growth hormone levels proved to be low, with increased serum levels of big-IGF-II. This is indicative of non-islet cell tumour hypoglycaemia. The patient received prednisone which resulted in an improvement in the blood glucose values but the morning hypoglycaemia remained, so that nightly intravenous glucose administration continued to be necessary. Therefore, growth hormone was added to the treatment which resulted in a complete disappearance of the hypoglycaemias. The patient died within 6 months of the diagnosis having been established.

Generalized lipodystrophy (GLD) is characterized clinically by an almost complete lack of fat in adipose tissue. Traditionally, GLD can be divided into congenital and acquired types according to the clinical course and underlying etiologies. Here, we describe a boy with a probable diagnosis of acquired GLD. He showed recurrent panniculitis since early infancy, and short stature with delayed skeletal age (3 years less) and low levels of insulin-like growth factor-1 (IGF-1) and IGF binding protein-3. Growth hormone (GH) deficiency was confirmed by GH provocative tests (peak GH below 5 microg/L). In addition to slow progressive loss of subcutaneous fat tissue, he also suffered from hepatosplenomegaly, recurrent febrile episodes in association with painful nodular skin lesions and abdominal pain. The diagnosis of lipodystrophic panniculitis was confirmed after skin biopsy. The febrile episodes and skin lesions responded to oral corticosteroid with the progression of time. Acquired GLD with GH deficiency (e.g., recurrent panniculitis) may occur as a result of chronic inflammation over the pituitary stalk and pituitary gland. The use of steroid and GH replacement may alleviate this disorder.

We report a case of splenic tumor associated with severe hypoglycemia. The patient was a 69-year-old man with a large splenic tumor. He had suffered from relapsing hypoglycemic attacks and the lowest serum glucose level (4 mg/dl). He died 34 months after the onset of symptoms of left abdominal pain. Autopsy revealed large tumors in the spleen, 3 medium sized tumors in the lungs, and several small tumors in the liver. Microscopic studies of the splenic tumors revealed a hepatocellular carcinoma which showed a strongly positive reaction against anti-PIVKA-II and anti-"hepatocyte" antibodies. Several bile ductules thought to be heterotopic remnants of the liver tissues were found in the capsule of the spleen, adjoining the splenic tumor. It was suggested that the tumor originated from one of these ductules. Electron microscopic analysis showed numerous endocrine-like granules of every tumor cell, and 87-165 times stronger mRNA expression of insulin-like growth factor-II was measured in the tumor tissues when compared with normal liver tissue. Owing to these results, we believe that this is the first report of hepatocellular carcinoma that had developed from a liver tissue in the spleen.

Allium tuberosum Rottler ex Spreng (ATRES) has been used as a traditional medicine for the treatment of abdominal pain, diarrhea, and asthma. In this study, we investigated the hair growth promoting activities of ATRES on telogenic C57BL6/N mice. Hair growth was significantly increased in the dorsal skin of ethanol extract of ATRES treated mouse group compared with the control mouse group. To enrich the hair promoting activity, an ethanol-insoluble fraction was further extracted in sequence with n-hexane, dichloromethane, ethyl acetate, n-butanol, and distilled water. Interestingly, we found that extraction with n-butanol is most efficient in producing the hair promoting activity. In addition, the soluble fraction of the n-butanol extract was further separated by silica gel chromatography and thin layer chromatography (TLC) resulting in isolating four single fractions which have hair growth regeneration potential. Furthermore, administration of ATRES extracts to dorsal skin area increased the number of hair follicles compared with control mouse group. Interestingly, administration of ATRES extract stimulated the expression of insulin-like growth factor-1 (IGF-1) but not of keratin growth factor (KGF) or vascular endothelial growth factor (VEGF). Taken together, these results suggest that ATRES possesses strong hair growth promoting potential which controls the expression of IGF-1.

BACKGROUND Non-islet cell tumor hypoglycemia (NICTH) is a newly recognized, but uncommon, paraneoplastic syndrome that is associated with tumors of mesenchymal origin. We report a case of NICTH associated with a gastrointestinal stromal tumor (GIST). CASE REPORT A 60-year-old man presented to the emergency department of our hospital after being found unconscious in his home. His serum blood glucose on hospital admission was 40 mg/dL. He reported a three-month history of diffuse abdominal pain, fatigue, and blurred vision. Laboratory medicine investigations showed reduced levels of insulin, C-peptide, insulin-like growth factor binding protein (IGFBP)-3, and insulin-like growth factor (IGF)-1, but his IGFBP-2 was increased. Computed tomography (CT) scan of the chest and abdomen showed an abdominal mass that involved the small bowel, mesentery, and omentum, with lesions in the right lung and the left rib. Histopathology of a CT-guided biopsy of the abdominal mass showed a low-grade sarcomatous spindle cell neoplasm that was positive for CD117 using immunohistochemistry and with an exon 11 c-KIT mutation. These findings were consistent with a diagnosis of GIST and treatment with imatinib commenced. CONCLUSIONS This case report has shown that hypoglycemia in the setting of low levels of insulin, C-peptide, IGF-1, and IGFBP-3 is suggestive of a diagnosis of NICTH, which should be investigated for an underlying source, which in this case, was confirmed to be a malignant GIST.

The aim of the study was to investigate the effects of recombinant human growth hormone on protein malnutrition and insulin-like growth factor-1 (IGF-1) and interleukin-2 (IL-2) gene expressions in chronic nephrotic syndrome. Eighty patients with chronic nephrotic syndrome were admitted to our hospital. The patients were included in the study period from January 2015 to December 2016 and were divided into two groups (40 cases in each group) according to the random number method. All the patients enrolled received symptomatic and supportive treatment. The observation group was injected subcutaneously with recombinant human growth hormone, while the control group was treated with Shenyankangfu tablets. The recovery time of the clinical symptoms, change in serum protein, caloric intake and protein metabolism after intervention were compared between the two groups. Changes in serum cystatin C, IGF-1 and IL-2 before intervention, and at 1 week, 1 month and 3 months after intervention were detected, and the adverse reactions in the two groups were observed during the treatment. After intervention, the improvement time of proteinuria, hypoproteinemia, edema and hyperlipidemia in the observation group was significantly shorter than that in the control group (P<0.05). The expression of transferrin, pre-albumin, albumin and total protein in the observation group was significantly superior increased compared to those in the observation group prior to intervention and the control group after intervention (P<0.05). In addition the caloric intake, protein intake and urea nitrogen survival rate in the observation group were significantly superior to those in the observation group prior to intervention and the control group after intervention (P<0.05). At 1 week, 1 month and 3 months after intervention, the levels of serum cystatin C, IGF-1 and IL-2 in the observation group were markedly obviously lower than those in the control group during the same period (P<0.05). The total proportion of allergy, systemic pruritus, nausea and vomiting, abdominal distension and abdominal pain in the observation group was obviously lower than that in the control group (P<0.05). Compared with the traditional Chinese medicine Shenyankangfu tablets applied in the control group, the recombinant human growth hormone used for patients with chronic nephrotic syndrome can improve the clinical symptoms more quickly, regulate the protein metabolism and reduce the inflammatory response in the body, which also has fewer adverse reactions and higher safety.
