BACKGROUNDSurgery of pituitary adenomas invading cavernous sinus has always been thought as a challenge due to the complex anatomical structures and high risk of complications. The purpose of this study was to evaluate endoscopic transsphenoidal approach to pituitary adenomas invading cavernous sinus.

METHODSThe clinical data of 22 patients who admitted to Xuanwu Hospital with pituitary adenomas invading cavernous sinus were analyzed retrospectively. All patients underwent endoscopic transsphenoidal surgery. To expose the surgical field sufficiently, the opening of sellar floor was exceeded the bone overlying the invaded cavernous sinus, and synthetic dura was used to repair and strengthen the sella floor for preventing the leak of cerebrospinal fluid.

RESULTSAmong 22 patients, total resection was achieved in 14, subtotal resection in 5, and partial resection in 3; no patient underwent insufficient resection. Visual symptoms improved in 7 of 9 patients. In one patient diplopia disappeared. Headache was relieved to various extents in all patients. No serious complications were found. Patient's hospital stay ranged from 7 to 20 days.

CONCLUSIONThese data suggest that the endoscopic transsphenoid approach is a safe, minimally invasive, and efficient surgical technique, which might be an important therapeutic strategy for the pituitary adenoms invading cavernous sinus.

OBJECTIVETo explore the relationship between the E-cadherin catenin complex and invasiveness of pituitary adenoma.

METHODSThe expression of E-cadherin catenin complex was determined by immunohistochemistry in 78 cases of human pituitary adenomas including invasive adenoma 44 cases, noninvasive adenoma 34 cases and the relativity of their expressions with hormone-producing, pituitary apoplexy and necrosis or cystoid change, tumor diameter were analyzed.

RESULTSThe invasive group had a significantly lower expression of E-cad and alpha-cat than that of noninvasive group (chi-squared = 13.969, P < 0.01). There was no statistical significance for beta-cat expression between the invasive group and noninvasive group (chi-squared = 0.430, P > 0.05). Moreover, the expressions of beta-cad and alpha-cat were significantly lower in macro-adenoma group than that in micro-adenoma group (chi-squared = 5.038, P < 0.05). The expression of E-cad was significantly lower in endocrine inactive group than that in endocrine active group (chi-squared = 4.614, P < 0.05). The expression of beta-cat was significantly lower in the group with apoplexy and necrosis than that in the group without apoplexy and necrosis (chi-squared = 6.701, P < 0.05).

CONCLUSIONSThe reduction of E-cad catenin complex is related to invasiveness and clinical pathological characteristics.

OBJECTIVETo optimize the conditions of the vacuum belt drying process (VBD) for drying Panax notoginseng extract and compare with methods of vacuum freezing drying and spray drying.

METHODThe optimum conditions of VBD were obtained by orthogonal design and validated by determinations of moisture content of the dried product and recovery of active ingredients. Experiments on different drying methods were also conducted.

RESULT AND CONCLUSIONThe optimum conditions are as follows, the feeding speed was 15 mL x min(-1), the belt speed was 4 mm x min(-1), and the heating temperature was (105, 100 degrees C). Comparing with the drying methods of vacuum freezing drying and spray drying, vacuum belt drying possesses some advantages, such as higher recovery of active ingredients, less moisture content of dried product and better overall yield.

OBJECTIVETo explore the relationship between gene expression of human telomerase reverse transcriptase (hTERT) and its clinical characteristics in leukemia.

METHODSThe protocol of RT-PCR was used to detect the hTERTmRNA expressing levels in peripheral blood samples from leukemic patients under primary treatment(n=42), in complete remission(n=21), with recurrent leukemia (n=4); and from normal subjects (n=5), respectively.

RESULTSThe positive percentage of hTERTmRNA expression was 73.81% for the primary treatment cases, and 19.05% for the complete remission cases. All of the recurrent cases gave positive results. One of the normal controls presented low level of hTERTmRNA expression. The expressing level of hTERTmRNA in primary treatment cases was 0.64+/-0.21, in complete remission leukemia 0.31+/-0.16, in recurrent cases 0.84+/-0.09, and in normal controls 0.10.

CONCLUSIONThe activation of telomerase may be an essential factor in the development of leukemia and usually be the late event in its progression. As an indicator of leukemia cell, the detection of hTERT mRNA may be used in clinical analysis, disease monitoring and prognosis judgement.

OBJECTIVELeft ventricular diastolic dysfunction is common in cardiovascular diseases. Hypertrophic cardiomyopathy(HCM) is a typical disease with diastolic dysfunction. We analyzed the association between the left ventricular flow propagation velocity (FPV), quantified by color M-mode Doppler and as an indicator for diastolic dysfunction, and clinical outcome in patients with HCM.

METHODSStandard echocardiography including FPV was performed in 43 cases with HCM and 22 control cases without a clear history of heart disease. All eligible cases were followed up to more than 1 year.

RESULTSHospitalization rate due to emerging atrial fibrillation/flutter was 21%, due to emerging ventricular tachycardia was 16%, due to heart failure was 26%, and due to other events was 14% in HCM patients. FPV [(31.6 ± 11.5) cm/s vs. (68.3 ± 18.3) cm/s, P < 0.01] and FPV/E (0.49 ± 0.20 vs. 1.18 ± 0.41, P < 0.01) were significantly lower in HCM group than in control group. PV/E was an independent predictor for atrial fibrillation/flutter and heart failure, IVST was independent predictor for VT (χ(2) = 5.181, P = 0.0228), LAD (χ(2) = 6.172, P = 0.0130) and FPV/E (χ(2) = 3.932, P = 0.0474) were independent risk factors for total cardiac events.

CONCLUSIONThe incidence of atrial fibrillation and heart failure were closely related with left ventricular diastolic dysfunction in HCM patients and FPV/E was independent predictor for clinical cardiovascular events.
