Objective To investigate the expression and significance of β-catenin and p28GANK in residual hepatocellular carcinoma (HCC)cells after transcatheter arterial chemoembolization (TACE).Methods We collected forty-five cases of surgical specimens of hepatocellular carcinoma after TACE ( TACE group ) and thirty cases of surgery without any treatment (pure surgery group).The expression of β-catenin and p28GANK were detected by using immunohistochemical SP method and compared between the two groups .Results The positive expression of β-catenin and p28GANK in TACE group were 77.78%and 75.56%respectively,which were significantly higher than those in pure surgery group (46.67%and 53.33%respectively,P<0.05).In the residual hepatocellular carcinoma cells of TACE group ,the positive expression of β-catenin showed correlation with the positive expression of p28GANK(Φ=0.318,P =0.033).The high expression of β-catenin and p28GANK were closely related to portal vein thrombosis and distant metastasis (P<0.05).Conclusion The ex-pression of β-catenin and p28GANK in the residual hepatocellular carcinoma cells were increased significantly after TACE.The high expression of β-catenin and p28GANK were closely related to portal vein thrombosis and distant metastasis.The high expression of β-catenin and p28GANK may be one of the reasons of hepatocellular carcinoma invasiveness and metastasis .

Objective To investigate the relationship between the liver pain and the short-term curative effect in patients with primary hepatocellular carcinoma(HCC)after transcatheter arterial chemoembolization(TACE).Methods According to the degree of liver pain,118 HCC patients after the initial TACE treatment were divided into two groups:group A(with no complaint of serious liver pain)and group B (complaining of severe liver pain).Short-term curative effects at the fourth and sixth week after initial TACE were compared between the two groups,and the factors related to the liver pain after TACE were analyzed.Results Four to six weeks after the initial TACE,CT scan was performed in all patients.Based on the RECIST criteria the short-term curative effects were evaluated.The CR,PR,SD,PD of group A and B were 0%.1.45%.88.41%,10.14%and 0%,14.29%.81.63%,4.08%,respectively.The difference in OR(CR +PR)between two groups was statistically significant(P=0.0087).The postoperative liver pain was probably related to the preoperative tumor blood supply pattern,the tumor capsule.the cirrhosis and the type of iodized oil deposit.The type of iodized oil deposit showed a negative correlation with the grade of liver pain (r=-0.539,P＜0.001).Conclusion The liver pain occurred after TACE is a useful suggestive sign,which indicates that a good curative result will be obtained.It is of clinical significance to make a full understanding of the relationship between the liver pain and the therapeutic effect.

Solitary fibrous tumor (SFT) in bladder is extremely rare. In this study, we reported one case of bladder SFT and reviewed the only ten cases of the disease that had been reported so far. The patient suffered from residual urine sensation and urethral pain. Cystoscopy revealed a 7-cm protruding mass at the dome of the bladder, and bladder mucosa biopsy showed normal differentiation of the bladder mucosa with a small amount of inflammatory cells. Radical resection of the tumor was performed in this patient. Pathological examination found uniform, haphazardly arranged spindle cells, the majority of which were CD34-positive and Vimentin-positive and proved that the mass was a solitary fibrous tumor. Within a period of 9 months of follow-up, no reoccurrence was found.

ObjectiveTo analyze the clinical features,diagnosis and treatment of male idiopathic hypogonadotropic hypogonadism (IHH).MethodsClinical data of 92 male IHH cases were analyzed retrospectively.ResultsThe mean age at evaluation was 21.0 ± 3.2 yrs,and 52 patients were diagnosed with Kallman syndrome (KS; IHH with anosmia/hyposmia) while the remainder were normosmic IHH (nIHH).All had normal radiological imaging of the hypothalamic and pituitary areas.The level of serum LH,FSH and T was low,and the clinical parameters (development of secondary sexual characteristics,sexual function,and serum testosterone levels.) were significantly improved after hormone replacement therapy.ConclusionsDiagnosis and differential diagnosis of IHH can be clearly defined based on clinical features and laboratory results.Hormone replacement therapy is an effective treatment option.

Objective:To explore the structural alterations in functional brain areas of patients with diabetic peripheral neuropathy (DPN) using voxel-based morphometry (VBM), and to investigate the abnormal region of grey matter and its distribution in DPN.Methods:A total of 124 patients with DPN and 88 patients with type 2 diabetes without DPN (NDPN) diagnosed in Haikou Hospital and the First Affiliated Hospital of Guangdong Pharmaceutical University from June 2019 to December 2020 were selected as the study subjects, and 40 healthy volunteers matched with gender and age were included as the control group.All subjects underwent whole-brain MRI examination, and 3D-T1WI data were collected for post-processing and analysis based on voxel morphological analysis.Results:Compared with NDPN patients, decreased gray matter volume in DPN patients was observed in the bilateral anterior central gyrus and thalamus, with statistical signifcant difference ( P<0.05), and there was no significant difference between the two sides ( P>0.05). Compared with healthy control group, decreased gray matter volume in DPN was observed in the the bilateral anterior central gyrus, central posterior gyrus, superior frontal gyrus and thalamus, with statistical signifcant difference ( P<0.05) and there was no significant difference between the two sides ( P>0.05). Conclusions:DPN patients also have decreased volumes of the brain greymatter, suggesting that the occorrence of DPN patients may be caused by the of injury of central structure.
