Objective:To compare the clinical characteristics in primary hyper(-) parathyroid hormone (PHPT) of the different patholog-ic types. Methods:Clinical data of 140 patients with PHPT proved by operation and pathology during January 2010 to June 2016 were retrospectively analyzed. Results:A total of 140 PHPT patients, including 13 (9.29%) cases of parathyroid carcinoma (PC), 27 (19.29%) cases of parathyroid hyperplasia (PH), and 100 (71.43%) cases of parathyroid adenoma (PA). The duration of the PC group was longer than the PH group and the duration of the parathyroid adenoma (PH) group was longer than the PA group (P<0.05). The percentage of young patients with PC was higher than in the other two groups (P=0.003). The diameters of the PC group were larger than those of the other two groups, and those of the PA group were larger than those of the PH groups (P<0.05). Blood calcium, parathyroid hor-mone (PTH), AKP, fasting blood glucose (FBG), alanine aminotransferase (ALT), aspartate aminotransferase (AST), glutamete transpepti-dase (GGT), blood urine nitrogen (BUN), creatine (CRE), urinary calcium, and phosphorus of the PC group were higher than in the oth-er two groups (P<0.05). The blood calcium, PTH, alkaline phosphatase (AKP), urinary calcium of the PH group were lower than those in PA group (P<0.05). The proportion of ostalgia was 46.15%(6/13), 44.44%(12/27), and 49.00%(49/100). No statistical difference was observed (P>0.05). The postoperative calcium level of PC group was lowest (P<0.001), and the highest was of PTH (P<0.001). The pro-portions of clinical manifestation of the urinary system, digestive system, and nervous system in the PC group were 76.92%(10/13), 76.92%(10/13), and 15.38%(2/13), respectively, and these values were the highest in the three groups (P<0.05). The proportion of the clinical manifestation of the urinary system of the PH group was higher than that of the PA group. The fracture rate (30.77%, 4/13) and constipation rate (38.46%, 5/13) of the PC group were the highest among the three groups (P<0.05). Conclusion:The duration of patients with PC was the longest among the three groups. The percentage of young patients with PC was the highest. The abnormal parathyroid glands in the PC group were the heaviest. The PC group exhibited the lowest postoperative calcium level and the highest PTH level. The biochemistry and clinical manifestations of PC were obvious.

Objective To evaluate the effects of high intensity focused ultrasound (HIFU) on hepatic cancer cells spreading in blood.Methods AFP mRNA in peripheral blood of 19 patients with hepatocellular carcinoma was detected before and after HIFU therapy by RT PCR.Results ①Before HIFU therapy, 11 of 19 cases were AFP mRNA positive (57.9%), while the control group were all negative. AFP mRNA was correlated with some clinical parameters such as serum AFP level, tumor size, portal vein embolism and extrahepatic metastasis ( P 0.05). ③After one week of HIFU therapy, the AFP mRNA positive rate of the group with tumor size less than 8 cm was much lower than that of tumor size larger than 8 cm ( P

This study is to investigate the effect of artesunate on transforming growth factor-beta1 (TGF-beta1) induced epithelial-mesenchymal transition (EMT) and its possible mechanism. After the in vitro cultured RLE-6TN cells were treated with TGF-beta1 then artesunate intervened on it, after 24 h, expression of the markers of mesenchymal cell was assayed using Western blotting and real-time PCR analysis. Western blotting was also used to detect the effect of TGF-beta1 on the Smad3 and Smad7 expressions of RLE-6TN cells. Morphological alterations were examined by phase-contrast microscope, and ultrastructure changes by electron microscope. Incubation of RLE-6TN cells with TGF-beta1 resulted in the up-regulation of the expression of the mesenchymal cell markers, after artesunate intervened on it, resulted in the down-regulation of the expression. Meanwhile, incubation with artesunate intervened on RLE-6TN cells could lead to the apparent down-regulation of the expression of Smad3 and up-regulation of Samd7 and the transition of RLE-6TN cells to mesenchymal-like by TGF-beta1 induction, after artesunate intervened on it, RLE-6TN cells to epithelial-like. TGF-beta1 induced epithelial-mesenchymal transition process; artesunate can inhibit TGF-beta1-induced epithelial-mesenchymal transition process, the possible mechanism is up-regulation of the expression of Smad7 and down-regulation of the expression of Smad3, meanwhile inhibits phosphorylation of Smad3.

OBJECTIVETo explore effect of Qindan Fuzheng Capsule (QFC) on ultrastructure of cardiomyocytes and hepatocytes injured by high microwave radiation in rats.

METHODSEighteen adult Wistar rats were equally divided into 3 groups in random: rats in Group A were untreated as the normal control, rats in Group B received 6 min microwave radiation (100 mW/cm2 high power) to cause injury of cardiomyocytes and hepatocytes, and Group C received the same radiation but treated with QFC perfusion, 2 mL (equivalent to 4.75 g crude drug) once a day, for 7 successive days, starting from 6 h after radiation. All rats were sacrificed 7 days later, their fresh tissue of heart apex and right lobe of liver were taken and prepared to routine transmission electron microscopy specimen for ultrastructural observation.

RESULTSCompared with Group A, different degrees of ultrastructural changes on nuclei and organelle were observed in Group B and C, but the injury in Group C was significantly milder than that in Group B, showing normal sized cells with good structure approximate to the morphology in Group A.

CONCLUSIONSQFC showed protective effect on microwave radiation injured ultrastructural changes in rats' cardiomyocytes and hepatocyte. Its mechanism was possibly correlated with the suppression of lipid peroxidation and the improvement of metabolism in myocardial and hepatic cells.

OBJECTIVETo analyze the relationship between the pulse pressure (PP) and atherosclerotic renal artery stenosis (ARAS) in middle-age and eldery paients with hyperensio, so as to provide the basis for the diagnosis and treatment of ARAS.

METHODSWe tetro spectively analyzed the data of 257 patients with hypertension undergoing renal arteriography at General Hospital of PLA between 2009 and 2014. Their mean age was (64.09 +/- 7.81) years. According the results of arteriography, they were divided into two groups: ARAS group (n = 145), and non-ARAS group (n = 112). Their PP and multinomial clinical indexes with ARAS were statistically analyzed.

RESULTSSingle factor correlation and Logisitic analysis showed that age, PP, serum creatinine (SCr) levels, and new onset of hypertension after 50 years of age were strongly positively related to ARAS. The age and PP and SCr was a team of continuous variable.

CONCLUSIONPP was the first new risk factor of ARAS in middile-aged and elderly patients with hypertension. It is suggested that PP may be a early predictive indicator and a new therapeutic target for ARAS.

OBJECTIVETo explore the values of tissue factor (TF) and vascular endothelial growth factor (VEGF) expressions on peripheral CD14+ monocytes in disease assessment, prognosis, and short-term efficacy evaluation of non-Hodgkin lymphoma (NHL) patients.

METHODSTF and VEGF expressions on CD14+monocytes in 47 NHL patients (disease group) before chemotherapy and after 4 chemotherapy cycles and in 30 healthy subjects (control group) were detected by flow cytometry, and the potential relationship among TF, VEGF, International Prognostic Index (IPI), and short-term efficacy were analyzed.

RESULTSTF and VEGF expressions on CD14 + monocytes in disease group were significantly higher than those in control group ( all P <0. 01) and positive correlation was showed between them (r = 0. 708, P = 0.00). TF and VEGF expressions in Ann Arbor stage III and IV (n = 22 and 19) , symptomatic (n = 22) , lactate dehydrogenase (LDH) increased (n = 21) , Eastern Cooperative Oncology Group (ECOG) score 2-4 (n = 12) and extranodal lesions >1 (n = 16) groups were significantly higher than those in Ann Arbor stage II (an = 6) , asymptomatic (an =25) , LDH normal (n = 26) , ECOG score 0-1 ( n = 35) and extranodal lesions ~1 ( na = 31) groups, respectively (all P <0.05). The expressions of TF and VEGF on CD14 + monocytes in high-risk (n = 7) or high-middle-risk (n = 11) groups were significantly increased compared with low-risk (n = 15) or low-middle-risk(n = 14) groups, respectively (all P <0. 01). TF and VEGF expressions in non-remission group before chemotherapy (n = 11) were both obviously higher than those in remission group (an = 36, all P <0. 01) , and after chemotherapy their expressions in remission group were significantly lower than those before chemotherapy (all P <0. 01) , while such significant changes were not observed in the non-remission group ( all P > 0. 05).

CONCLUSIONThe high expressions of TF and VEGF on peripheral CD14 + monocytes can be useful markers in dis-ease assessment, prognosis evaluation and short-term efficacy observation of NHL patients.

Ribavirin is a broad-spectrum antiviral agent and glycyrrhizin has activities of anti-inflammation, immunoregulation and anti-viral infections. To enhance antiviral efficacy and weaken side-effects of ribavirin, antiviral effects of the combination of glycyrrhizin and ribavirin were studied in the present study. Firstly, a mouse model of viral pneumonia was established by inoculation of influenza H1N1 virus. Protective effects of glycyrrhizin and ribavirin used alone or in combination against H1N1 virus infection in mice were evaluated based on the survival rate, lung index and virus titer in lungs of mice. Results showed that the combination of glycyrrhizin and ribavirin significantly inhibited the lung consolidation with a 36% inhibition ratio on the lung swell of infected mice. The combination of the two drugs exhibited synergetic effects on survival of infected mice. The combination of 50 mg · kg(-1) · d(-1) glycyrrhizin and 40 mg · kg(-1) · d(-1) ribavirin resulted a 100% protection for infected mice with a synergetic value of 36, which was significantly higher than the control group and each drug alone. This combination also resulted a significant drop of lung virus titer (P < 0.01), as well as inhibition on the production of proinflammatory cytokines IL-6 (P < 0.01), TNF-α (P < 0.01) and IL-1β (P < 0.05) induced by virus infection compared to the control. The treatment of ribavirin plus glycyrrhizin was more effective in influenza A infection in mice than either compound used alone, which suggested a potential clinical value of the combination of the two agents.
