Objective] To discuss the relationship between CT perfusion imaging and TCM syndrome of liver cancer patients. [Methods]Through testing the Perfusion parameters of Lesions, surrounding liver tissue and liver tissue perfusion in the distance, we may explore the correlation among perfusion parameters, TCM syndrome of primary liver cancer, then explore the phase rule.[Results] There exists significant difference between perfusion parameters and TCM syndrome of liver cancer patients. Hepatic arterial perfusion(HAP), portal venous perfusion(PVP):deficiency syndrome of both liver and kidney yin>syndrome of heat-damp>syndrome of qi stagnation and blood stasis>syndrome of hepatic stagnation and spleen deficiency;Hepatic perfusion index(HPI):syndrome of hepatic stagnation and spleen deficiency>syndrome of qi stagnation and blood stasis>syndrome of heat-damp>deficiency syndrome of both liver and kidney yin. Child-Pugh classification: syndrome of hepatic stagnation and spleen deficiency(5.34 ±1.46),syndrome of qi stagnation and blood stasis(6.82±0.94),syndrome of heat-damp(8.34±1.12),deficiency syndrome of both liver and kidney yin(9.01±1.19).There exists significant difference between Child-Pugh classification and TCM syndrome of liver cancer patients(P<0.05). The result shows that a high positive correlation between AF, PI and Child-Pugh classification(P<0.05);There exists a negative correlation between PF and Child-Pugh classification(P<0.05).[Conclusion] CT perfusion parameters can be used as an objective indicator of middle-late stage of TCM syndrome of liver cancer patients.

Eight isolates of Colletotrichum gloeosporioides isolated from host plants Cunninghamia lanceolata lanceolata and Euonymus japonichum, respectively, were cultured on MMC medium containing KCIO3 to select chlorate-resistant and nitrate non-utilizing mutants (Nit). All the Nit mutants obtained by this way belong to one of 3 kinds of the following phenotypes: the nitrate reductase structural locus (nit1), the nitrate-assimilation pathway-specific regulatory locus(nit3), and the molybdenum-containing cofactor locus(nitM). The higher mutation frequency on MMC amended with increasing concentration of KCIO3 was induced, and various nitrogen sources were able to influence production of the phenotypic classes. Seven of the 8 isolates tested were self-compatibility in which the two mutants with different phenotypes from the same isolate could genetically complement. The two isolates frail C. lanceolata belong to the same vegetative compatibility group (VCG), the other six isolates belong to distinctive VCGs.

Objective To study the prognostic factors in patients of HCC after hepatectomy by Cox proportional hazard.Methods 145 patients operated on for HCC from 1986 to 1996 were followed up to the end of 1999. Seventeen possible factors associated with long survival were analyzed by Kaplain Meier Log rank estimation. A multivariative survival analysis of these individual variables was undertaken using the cumulative survival rate by the computer′s Cox proportional hazard. Results The overall cumulative survival rate at 1?3?5?7?10?12 years was 75 0%?44 4%?29 5%?23 5%?21 2%? and 16 9%, respectively. Results showed that the way by which a tumor was found?tumor size?portal thrombi?satellite nodule?UICC TNM stage?cutting margin?radical resection were the prognostic factors by individual variable analysis;A multivariative analysis showed that tumor finding mode?UICC stage?cutting margin?recurrence?radical resection were associated with prognosis.Conclusion The prognostic factors of HCC focused on two aspects: early diagnosis and treatment method. UICC TNM stage is most predictive for prognosis. Cutting margin of more than 1 cm is needed for long term survival.

OBJECTIVETo evaluate the therapeutic effect of Parkinson's disease combined with overactive bladder syndrome (GAB) treated with combined therapy of oral administration of Tolterodine with low dose and electroacuponcture.

METHODSSixty cases of Parkinson's disease combined with GAB were randomly divided into a combined acupuncture and medication group (group A) and a medication group (group B), 30 cases in each group. In both groups, Madopar basic doses were same, and anticholinergic agents such as Artane were stopped. In group A, Tolterodine was orally taken for 1 mg, twice a day; Baihui (GV 20), Sishengcong (EX-HN 1) and Yintang (EX-HN 3) were punctured with electroacupuncture, once a day. In group B, Tolterodine was orally taken for 2 mg, twice a day. After 6 weeks, the changes of urination and UPDRS III scores were observed, and the adverse reactions were recorded in both groups.

RESULTSAfter treatment, the frequency of average urination of 24 hours, frequency of incontinence of 24 hours and average urine volume at a time were obviously improved (all P < 0. 01), of which, the above items in group A were superior to those in group B (all P < 0. 05) the UPDRSIII score in group A was superior to that in group B (P < 0.05). The adverse reactions in group A were less than those in group B.

CONCLUSIONThe therapeutic effect of Parkinson' s disease combined with GAB treated with combined therapy of Tolterodine with low dose and electroacupuncture is superior to that of complete dose of Tolterodine with oral administration, with less adverse reactions. And it also can improve the motor symptom of Parkinson's disease patients.

Objective To evaluate the prognostic value of China Classification System and TNM staging in patients with liver cancer undergoing resection. Methods From Jan 1986 to Dec 2000, 246 patients underwent resection of liver cancer. At least three years of follow-up was made in these 246 cases. Results The 1, 3, 5, 7, and 10-year disease-free survival rates were 55%, 30%, 25%, 20% and 18%, respectively. The 1,3,5,7,and 10-year disease-free survival rates predicted by China Classification System and TNM staging were statistically different and positively correlated with each other. Differences of survival rate between stageⅠa、Ⅰb、Ⅱa 、Ⅱb and Ⅲ by China Classification System were all statistically significant. Conclusions Based both on tumor extension and liver function, China Classification System was more accurate in than TNM stage predicting the prognosis of liver cancer patients undergoing resection.

Objective To investigate the clinicopathologic features and treatment of thyroid microcarcinoma (TMC). Methods From January 1997 to December 2006,311 patients who underwent surgery and defined as TMC(tumor size≤1 cm)were enrolled. Results TMC was identified incidentally by frozen pathologic examination on thyroidectomy specimens in tentative benign goiters in 181 patients; another 130 patients with clinically detectable primary tumors or suspected nodal metastases were grouped to as clinically overt TMC. The clinically overt TMC had a higher incidence of bilateral multifocal tumors (18.5%vs.9.4%,P=0.03),and cervical lymph node metastases(27.7%vs.10.5%,P=0.000)than that in clinically occult TMC group. Conclusion TMC may vary considerably in clinical and biologic behaviors between these two subtypes: clinically overt and occult. Lobectomy for single lesion, total or near total thyroidectomy for multifocal with central compartment nodal dissection should be performed, lateral nodal dissection was not carried out unless US or physical examination detected nodal metastases. Lobetomy, subtotal or more limited thyroidectomy for occult TMC, diagnosed incidentally following thyroid surgery for initially tentative benign thyroid disease, could all be treatment of choice depending on the preference of surgeons.

OBJECTIVETo evaluate the prognostic value of CLIP score system for patients with resection of HCC.

METHODSA retrospective survey was carried out in 174 patients undergoing resection of HCC from January 1986 to June 1998. 153 of 174 patients with curative resection were followed up for at least three years. Disease-free survival rate was defined as the time relapsed from the date of image diagnosis and either the date of death or the date of the latest follow-up visit, with final evaluation at June 30, 2001. Recurrences were classified into early ( 3 year) recurrence. Risk factors for recurrences and prognostic factors for survival in each group were analyzed by the chi-square test, the Kalain-Meier estimation and the COX proportional hazards model respectively.

RESULTSThe 1-, 3-, 5-, 7-, and 10-year cumulative disease free survival rates were 57.2%, 28.3%, 23.5%, 18.8% and 17.8%, respectively. The associated factors with early recurrence were as fellows: tumor size > 5 cm, microsatellite, venous invasion, tumor morphology, tumor extension, advanced TNM stages, CLIP scores, radical resection, and resection margin, respectively. But both CLIP scores and Child stage were associated with late recurrence. Univariate survival curves analysis expressed that Child grades, radical resection, resection margin, tumor size, microsatellite, venous invasion, tumor morphology, tumor extension, TNM stages, and CLIP scores were associated with prognosis. The multivariate analysis by COX proportional hazards model, the independent prognostic factors for survival were radical resection, resection margin, and TNM stages.

CONCLUSIONSCLIP score, which takes into account both liver function and tumor extension, has displayed a unique superiority in predicting the tumor early and late recurrence and prognosis. It could be an useful tool in predicting the patient recurrence and prognosis with resection of HCC. Meanwhile, it may help physicians to decide the more appropriate management in advance for patients with HCC.

OBJECTIVE: To study the clinical value of serum neuroglobin in evaluating hypoglycemic brain injury in neonates. METHODS: A total of 100 neonates with hypoglycemia were enrolled as subjects. According to amplitude-integrated EEG (aEEG) findings and/or clinical manifestations, they were divided into symptomatic hypoglycemic brain injury group (n=22), asymptomatic hypoglycemic brain injury group (n=37) and hypoglycemic non-brain injury group (n=41). The three groups were compared in terms of blood glucose, duration of hypoglycemia, levels of neuroglobin and neuron-specific enolase (NSE), and modified aEEG score. The correlation of neuroglobin with NSE and modified aEEG score was analyzed. The receiver operating characteristic (ROC) curve was plotted. RESULTS: Compared with the asymptomatic hypoglycemic brain injury and hypoglycemic non-brain injury groups, the symptomatic hypoglycemic brain injury group had significantly lower blood glucose and modified aEEG score, significantly higher neuroglobin and NSE levels, and a significantly longer duration of hypoglycemia (P<0.05). Compared with the hypoglycemic non-brain injury group, the asymptomatic hypoglycemic brain injury group had significantly lower blood glucose and modified aEEG score, significantly higher neuroglobin and NSE levels, and a significantly longer duration of hypoglycemia (P<0.05). Neuroglobin was positively correlated with NSE and duration of hypoglycemia (r=0.922 and 0.929 respectively; P<0.05) and negatively correlated with blood glucose and modified aEEG score (r=-0.849 and -0.968 respectively; P<0.05). The areas under the ROC curve of neuroglobin, NSE and modified aEEG score were 0.894, 0.890 and 0.941 respectively, and neuroglobin had a sensitivity of 80.8% and a specificity of 95.8% at the optimal cut-off value of 108 mg/L. CONCLUSIONS Like NSE and modified aEEG score, serum neuroglobin can also be used as a specific indicator for the assessment of brain injury in neonates with hypoglycemia and has a certain value in clinical practice.

The effect of Qizhi Jiangtang vapsule (QJC) on degree of dermal ulcer cicatrization in 2 type diabetic rats was studied. Except the rats for blank group, other male Wistar rats were used to establish type 2 diabetic model by feeding with high sugar and high fat diet for four weeks and intraperitonally injecting with 30 mg•kg⁻¹ streptozotocin (STZ). After that, the rats were divided into balanced groups according to blood sugar, and received corresponding drugs for treatment for 8 weeks. At the end of week 8, 2 cm diameter circular incision was done on the back of rats. After that, the rats were administered continuously for10 days. Area of ulcer surface was detected every two days. After the last administration, wound granulation tissues were cut down to conduct pathological examination and detect the expression of VEGF, PI3K, p-ERK protein in wound tissues. The results showed that compared with the model group, after application of Qizhi Jiangtang capsule (2.24 g•kg⁻¹), the wound was significantly reduced on day 6 and day 10 of wound formation; inflammation reaction on ulcer surface was significantly reduce; Qizhi Jiangtang capsule can increase VEGF expression in the wound tissues of diabetic rats, and inhibit ERK phosphorylation. It can be concluded that Qizhi Jiangtang capsule can promote skin ulcer healing for diabetes rats, and its mechanism may be related to regulating the expression of VEGA and p-ERK proteins.
