Objective To investigate the value of multislice spiral CT(MSCT,)in interventional therapy of the hepatocellular carcinoma(HCC)emphasising on transcatheter hepanc arterial chemoembolization(TACE).Methods MSCT were performed in 60 cases of HCC before interventional procedure,CT findings of hepatic artery phase,portal venous phase and hepatic venous phase were observed respectively,among which CTA were done in 15 cases,and the anatomy of celiacartery and its branches were observed in 45 cases.The schemes of interventional therapy were worked out according to the findings of MSCT.Results MSCT showed 250 lesions,10 cases of tumor thrombosis in portal vein and 19 cases of hepatic arterioportal shunt.There was no significant difference between MSCT and digital subtraction angiography(DSA)in positive rate of in showing number of tumor or tumor thrombosis in portal vein(P＞0.05),but the 3D construction of celiac artery branches in CTA was better than that in DSA,while angles between celiac artery and abdominal aorta in MSCT were more convenient than that in DSA.MSCT showed 5 eases of hepatic artery original abnormality,according to that in DSA.Conclusion MSCT is of importance for guidance of interventional therapy of hepatocellular carcinoma.

Objective To investigate the current status of type 2 diabetic patients who failed to achieve the glycemic control target, and provide theoretic evidences for making corresponding strategies. Methods The 2 diabetic patients who failed to reach the glycemic target were recruited from 181 hospitals in 26 cities and received a standard questionnaire, the conditions of their blood glucose level, lifestyle intervention, blood sugar monitoring, and drug therapy were recorded. Totally 3 861 questionnaires with complete information were collected. And the causes which account for glycemic control status were analyzed. Results Among these patients, the mean HbA1c was 7.9%, the mean fasting plasma glucose was 8.2 mmol/L, and the mean postprandial plasma glucose was 11.5 mmol/L. Only 25.6% of patients take their diet control strictly as prescribed and 44. 5% of patients have little exercise. 35. 8% and 47.8% of patients did not monitor their fasting and postprandial plasma glucose,respectively. Glycemic control in the patients aged ＞ 60 years was similar to the younger patients, but the hypoglycemia incidence in the elder group reached 35.5%, which was higher than those in the other 2 groups (20.8% and 21.4%, both P＜0. 05 ). The proportion of patients with mono-therapy and combination therapy was 46. 1% and 51.7%, while the proportion with combination therapy rose in the patients aged ＞60 years (58.7%;Compared with the other age-groups, all P＜0.05 ). 75 % of patients have adjusted their drug administration regimen since initial treatment. Conclusions Inadequate or inappropriate drug therapy regimen is a major cause responsible for this poor glycemic control status. In addition, the unhealthy life styles, insufficient blood sugar monitoring, and poor compliance were also important causes. Thus, for these patients, it is necessary to further enhance patients' education, to improve life style intervention, as well as to select more effective, safer, and compliant drug therapy regimens. Finally, the glycemic control target for the elder patients should be more flexible.

[Summary]_ Transient neonatal diabetes mellitus is a kind of rare special types of diabetes. It should be distinguished from type 1 diabetes. Genetic analysis can be used to define the subtype of neonatal diabetes mellitus, which helps us to select the most appropriate treatment and to predict the disease recurrence. Sulfonylureas is able to improve insulin secretion in most patients with transient neonatal diabetes mellitus and provide effective glycemic control. A case of transient neonatal diabetes mellitus is reported in order to call attention to the diagnosis and treatment of this disease.

Objective:To investigate the efficacy of microsurgical treatment in cavernous sinus tumors.Methods:The clinical data of 87 patients with cavernous sinus tumor treated by microsurgery from January, 2010 to August, 2019 were analysed retrospectively. The surgical approaches and microsurgical skills for common tumors in Cavernous Sinus region were discussed. The follow-up included outpatient and telephone follow-ups, and the follow-up results were evaluated by KPS score.Results:Among the 87 cases, 57 were totally resected (65.5%), 14 were subtotal resected (16.1%) and 16 were major resected (18.4%). Hospitalisation ranged from 14 to 98 days, with an average of 29 days. Postoperative complications occurred in 30 cases with cranial nerve injury, 2 brain stem injury, 4 postoperative bleeding, 5 cerebrospinal fluid leakage, 4 infection, 1 Pituitary damage and 1 death. Prognosis and follow-up analysis showed 68 cases with KPS>60 and 66 with KPS>80 at 1 month after surgery; 74 with KPS>70 and 72 with KPS>80 at 3 months after surgery; 78 with KPS>80 by 12 months after surgery. During the follow-up period of 6-120 months, 3 cases died. Recurrence: 6 of incomplete resection of meningioma, were in 1-6 years after the surgery, 4 of incomplete resection of schwannoma in 1-8 years, 2 of pituitary adenoma respectively in 13 and 16 months after the surgery. There was no recurrence after reoperation. Two cases of chondrosarcoma, 3 of chordoma and 3 of germinoma were treated with radiotherapy, and during the follow-up, there was no progress of the focus. No tumor progression or recurrence was found in other cases during follow-up.Conclusion:Surgery of cavernous sinus tumor is difficult due to frequent postoperative complications. Reasonable preoperative plan, surgical approach and precise microsurgical techniques are the keys in reduction of postoperative complications and in the improvement of prognosis.

Taxus suspension cell culture has the potential to provide a sustainable source of anticancer drug paclitaxel (Taxol) and other taxoids. In the cell culture of Taxus chinensis, Taxuyunnanine C (Tc) is the primary taxoid. To design a rational strategy for redirecting the precursor fluxes from other taxoids into paclitaxel production, we employed Real-time Quantitative PCR (RQ-PCR) to understand the dynamic profiling of key biosynthetic pathway genes of palcitaxel and taxoids during the culture process. Six genes (TASY, TDAT, T5alphaH, TalphaH, T10betaH and T14betaH) were quantified under the process condition of double elicitation by 2,3-dihydroxylpropanyl jasmonate (DHPJA) (100 micromol/L on day 7 and day 12), and sucrose feeding (20 g/L) on day 7. This process treatment led to a high accumulation of Tc at (554.46 +/- 21.28) mg/L 8 days after the first elicitation. Then 9 days after the second elicitation, Tc production was as high as (997.72 +/- 1.51) mg/L. The early pathway genes TASY and TDAT were significantly up-regulated by 182-fold and 98-fold, respectively for the first DHPJA elicitation and by 208-fold and 131-fold, respectively for the second elicitation. The induction occurred after each elicitation lasted for about 24 h before their abundances decreased. Things are somewhat different in the case of the other four genes T5alphaH, TalphaH, T10betaH and T14betaH. For gene TalphaH, it was highly up-regulated by 3061-fold for the first DHPJA elicitation and by 1016-fold for the second elicitation. For the other three genes T5alphaH, T10betaH, T14betaH, they were up-regulated by 13-fold, 38-fold and 20-fold, respectively for the first DHPJA elicitation and by 7-fold, 16-fold and 6-fold, respectively for the second elicitation. The RQ-PCR results showed that there is tight correlation between gene expression and Tc accumulation. Gene expression was in accordance with Tc yield. Elicitation could improve expression of six genes. While along with culture course, high expression of the genes weakened. Elicitation for the second time would promote high expression of the genes again.
