Objective To explore the facial nerve functional recovery law after resection of acoustic neuroma,and the influence of tumor size on postoperative facial nerve function. Methods According to the House-Brackman (HB) facial nerve function classification method, 89 patients with acoustic neuroma were performed microsurgical resection with the ret?rosigmoid approach and facial nerve preservation. The HB classification method was used to evaluate the facial nerve func?tion at operation, 15 d, 45 d, 3 m, 6 m, 12 m and more than 12 m after surgery. The recovery pattern of neurological function after operation was analyzed. al. According to the tumor size, patients were divided into three groups: diameter < 30 mm group (n=23), 30-40 mm group (n=31) and≥40 mm group (n=35). The facial nerve function was compared between different groups with early postoperative (within 15 days) and long-term (more than 12 months). Results The facial nerve function was the worst in 15 days after operation (excellence rate was 52.81%), but the function was returned to normal in postopera?tive 3 months (excellent rate reached 80.90%). After postoperative 12 months, almost all patients returned to normal func?tion (excellent rate was 91.01%), and the facial nerve recovery was more smoothly (excellent rate was 92.13%). Tumor size had remarkable effect on facial nerve function in the early postoperative period (χ2=23.34, P<0.05), and long-term period (χ2=14.46, P<0.05). And tumor size was positively correlated with classification of facial nerve function in the early stage (r=0.476, P<0.05) and long-term stage (r=0.379, P<0.05). The excellent rates of postoperative facial nerve function were decreased with the increased diameters of tumor size. Conclusion The facial nerve function may appear deterioration in early postoperative period (within 15 days) in patients with acoustic neuroma, which can return to the normal level in 12 months. The diameter of tumor is one of important factors influencing the early and long-term prognosis of postoperative fa?cial nerve function.

OBJECTIVE: To explore the effects of Scrophulariae of cold nature and Aconite of hot nature on myocardial hypertrophy and neuroendocrine factors in rats and mice. METHODS: A mouse model of myocardial hypertrophy was established by hypodermic injection of isoproterenol. Sixty myocardial hypertrophy mice were randomly divided into five groups: normal control group, untreated group, metoprolol-treated group, Scrophulariae-treated group and Aconite-treated group. A rat model of myocardial hypertrophy was established by peritoneal injection of L-thyroxin. Fifty rats were randomly divided into five groups: normal control group, untreated group, captopril-treated group, Scrophulariae-treated group and Aconite-treated group. After 7-9 days of treatment with intragastric administration of the corresponding drugs, the effects of Scrophulariae and Aconite on left ventricular weight index (LVWI) and heart weight index (HWI) were determined. The concentrations of cyclic adenosine monophosphate (cAMP) in plasma and angiotensin II (Ang II) in myocardium were detected through radio-immunity method. Cardiocyte cross-section area was determined by using HE staining. RESULTS: Scrophulariae of cold nature could significantly reduce the LVWI, HWI and cardiocyte cross-section area, and could decrease the content of cAMP and Ang II. However, Aconite had no such effects. CONCLUSION: Scrophulariae of cold nature can inhibit myocardial hypertrophy through restraining the activity of sympathetic nervous system and decreasing the level of Ang II. The inhibition of Aconite of hot nature on cardiac hypertrophy is not significant.

Ezrin is an important membrane-cytoskeleton linker protein.It is highly related with tumor invasion and metastasis and indicates poor prognosis.It is reported that aberrant Ezrin expressed in many carcinomas,such as osteosarcoma and breast carcinoma.However,the complex mechanisms of Ezrin in tumor invasion and metastasis remain unclear.It is involved in several different tumor associated signal pathway based on different tumor types,including adhesion molecule signal transduction,Rho and Akt signal transduction.Therefore,research on the signal transduction of Ezrin has great significance for the understanding of cancer progression and Ezrin is probable to be a new treatment target.

Objective To summarize the practical experience of 2 cases of anemia following living related intestinal transplantation.Methods The clinical data of 2 cases of anemia following living related intestinal transplantation were studied retrospectively. After the surgical procedure regiments of blood transfusion, hemostasia, to cut down the dosage of some drug, to fill up raw material of hematopoientic system and requisite nutrition support were used to treat the patients. Results Four weeks later, the diseased conditions of the two patients became better and better. The index of hemoglobin were increased remarkably, to normal level 100 to 120?g/L.Conclusion Anemia is one of the common syndrome in living related intestinal transplantation. The correction of anemia is very important in treating such patients.

Objective To investigate the diagnosis and treatment of mammary duct ectasia. Methods Analysis was made retrospectively on the clinical data of 96 cases of mammary duct ectasia proved by operation and pathology from 1961 to 2000 in our hospital. Results Misdiagnosis was made in 72 cases (75%). According to the various clinical features, patients should be treated by different operation, including ductectomy, lumpectomy, segmentectomy, simple mastectomy, incision and drainage, fistulectomy and radical mastectomy. 88(91.7%) of the cases were cured and the other 18 patients did not get an obvious relief of the symptoms or got recurrence of the disease. Conclusions Mammary duct ectasia is easy to be misdiagnosed. Operation is the main method of treatment.

Objective To evaluate the effects of epidural capsaicin on pain threshold and nerve tissue structure in adult rats. Methods Twenty-four adult male Wistar rats weighing 250-300 g were used in this study. A catheter was inserted into epidural space at L5,6 according to the method of Philippe. 0.4 ml of capsaicin 0.1% (group A), 0.25% (group B) or 0.5% (group C) or 10% Tween 80 (control group) was injected via the epidural catheter. Pain threshold was measured by thermal stimulation of the tail before (baseline) and on the 3rd, 7th and 14th day after epidural capsaicin. The animals were then killed. The lumbar segment (L4-6) of the spinal cord and spinal nerve roots were removed immediately for light and electron microscopic examination. Results Pain threshold was significantly higher in group A, B and C than in control group (P

Objective To evaluate the diagnosis and surgical treatment of primary retroperitoneal extraadrenal pheochromocytoma(PREAP). Methods Clinical data of 17 cases with PREAP from 1976 to 2006 were analyzed retrospectively. Results It was not difficult for the diagnosis of PREAP based on the primary symptoms, including paroxysmal hypertension or persistent hypertension. PREAP is usually deep, large and invading on adjacent organs. B-uhrasound was used for preliminary screening. CT and MRI with high soft tissue resolution and multi directional imaging are of great value for correct diagnosis and determination of exact extent of the tumor in diagnosis of PREAP. 24 h urinary VMA output imcreased in 12 cases (92. 3%) and urinary catecholamine level was up to 526. 1 μg- Precise location of PREAP by 123I-MIBG is superior to that by 131I-MIBG. The diagnosis was tentative in 4 cases and definite in 13 cases. Complete tumor resection was achieved in 15 cases, among them 2 cases died on table due to inadequate preparation before surgery in 1970's. In the remaining 2 cases with huge tumors partial resection, silver clips were put in during operation to locate the extent of the tumors for further management after operation. Conclusions Locating and qualitative diagnosis before operation are valuable and once the patients are diagnosed as PREAP, they should receive exploratory laparotomy after an adequate preparation.

Objective:To investigate auricular lobule index difference in healthy young female of different height or weight, and to provide an additional reference for otoplasty of auricular lobule.Methods:Subjects were made up of 266 healthy young females of Henan residents. Their height, weight, physiognomic ear breadth, morphological ear breadth, physiognomic ear length, morphological ear length, auricular lobule length, auricular lobule breadth were measured and calculated. All the data were analyzed by SPSS 15.0 software.Results:We obtained the means, standard deviation of each items, and data were treated statistically. In the 266 subjects, average height was (162.9±4.1) cm, weight (55.3±6.5) kg, morphological ear breadth (4.9±0.6) cm, morphological ear length (2.9±0.3) cm, physiognomic ear breadth (6.2±0.4) cm, physiognomic ear length (3.3±0.3) cm, auricular lobule breadth (1.6±0.3) cm, auricular lobule length (1.8±0.2) cm, lobule physiognomic ear breadth index (25.6±4.9)%, lobule-physiognomic ear length index (53.69±7.69)%, and auricular lobule index (91.4±19.3)%. The differences among the indices mentioned above were of statistical significance ( P<0.05); the indices of subjects of different height were significantly different ( P<0.05); the indices of subjects of different weight were of no statistical difference. ( P>0.05). Conclusions:The subjects of different height or weight have no different morphological ear breadth, morphological ear length, physiognomic ear breadth, physiognomic ear length, auricular lobule length, lobule-physiognomic ear length index and auricular lobule index; hence, the indices are no related to body height and weight. However, the subjects of different height have different auricular lobule breadth and lobule-physiognomic ear breadth index.
