Objective To evaluate the therapeutic effect ofGuizhi-Fuling Pill combined with conventional western medicine therapy for diabetic peripheral neuropathy (DPN).Methods A total of 78 patients with DNP were randomly divided into treatment group (40 patients) and control group (38 patients).The patients in the control group were administrated with mecobalamin on the basis of conventional treatment. In addition to the therapy of control group,patients in treatment group were givenGuizhi-Fuling Pill. The patients in both groups were treated for 2 weeks.The level of homocysteine (Hcy) and sensory nerve conduction velocity (SNCV) and motor nerve conduction velocity (MNCV) in both groups were measured. Toronto clinical scoring system (TCSS) was used to evaluate the curative effect.Results The total effect rate in the treatment group was significantly higher than that in the control group (95.0%vs. 76.3%;χ2=5.616,P=0.018). After treatment, the MNCV of common peroneal nerve (46.1 ± 6.3 m/svs.42.5 ± 5.5 m/s;t=2.734,P<0.01 ), MNCV of median nerve (49.8 ± 5.2 m/svs.46.3 ± 5.9 m/s;t=2.607,P<0.05 ), SNCV of common peroneal nerve (38.5 ± 4.6 m/s vs. 35.4 ± 4.3 m/s;t=3.105,P<0.05 ), SNCV of median nerve (45.3 ± 5.2 m/svs. 42.3 ± 4.8 m/s;t=2.627, P<0.05 ) in the treatment group were significantly increased than those in the control group. The integral of TCSS (5.3 ± 3.1vs. 7.2 ± 2.9;t=2.823,P<0.01) and the level of Hcy (13.3 ± 3.2 μmol/Lvs. 17.1 ± 3.4 μmol/L;t=5.178, P<0.05) were significantly lower in treatment group than those in control group (P<0.05).Conclusions The Guizhi-Fuling Pill combined with conventional western medicine therapy could improve MNCV and SNCV and reduce the level of Hcy and improve the clinical effect.

Objective To study the growth suppression effect of 131 I labeled anti KDR monoclonal antibody on the tumor tissue of human bladder cancer subcutaneously implanted in SCID mice. Methods The SCID murine model was established by subcutaneous implantation of human bladder cancer in mice. The 131 I labeled anti KDR monoclonal antibody (3G9) was injected into the caudal vein of mice (experimental group). The anti KDR monoclonal antibodies and saline were injected into the caudal vein of the mice (control group and blank group, respectively). The growth suppression effect of 131 I labeled anti KDR monoclonal antibody on the tumor tissue of SCID mice bearing human bladder cancer was observed. Results Tumor tissue necrosis was found in the mice of the experimental group and the control group at 3 weeks after the injection. Compared with that in the blank group, the growth suppression ratio in the experimental group and the control group were 96.8% and 87.7%, respectively. Conclusion 131 I labeled anti KDR monoclonal antibody may be of potential clinical significance in the anti angiogenesis therapy for human cancer.

Objective To supply morphologic basis for designing the medial antebrachial neurocutaneou vascular flap. Methods Microanatomy and transparent specimens made by colored latex injection were applied to study the surgical anatomy of the medial antebrachial neurocutaneous nerve (MAN) and it's relationship to basilic vein, the origin, orientation,caliber of neurovascular cutaneous perforators and it's nutrient pattern to the MAN. Results The MAN got its blood supply by paraneural vessels which constituted of 4 cutaneous perforators' The paraneural vessels supply not only the MAN,but also it's adjacent flap. The MAN was accompanied by basilic vein about 1 cm away from it. Conclusion Along basilic vein,medial antebrachial neurocutaneous vascular flap could be designed and used to repair soft tissue defects around the elbow and wrist

Objective To evaluate the causes of the metamorphopsia in patients with reattached retina after scleral buckling surgery. Methods Amsler grid test, ophthalmoscopic examination, fundus fluorescein angiography (FFA) and optical coherence tomography (OCT) were performed on 79 patients (79 eyes) with reattached retina at the 2nd week, 2nd, 6th month and 1st year after scleral buckling operation. Results Two weeks after the operation, 51 patients (51 eyes, 64.56%) complained of metamorphopsia, and 44 patients (44 eyes, including 35 with and 9 without metamorphopsia) were examined by OCT and FFA. In patients with metamorphopsia, the results of OCT in 31 (88.57%) revealed abnormal macula with seven kinds consisting mostly of stratum neuroepithelium detachment (74.29%), while of FFA in 6 patients showed abnormal macular (17.14%) including 4 with neuroepithelium detachment (66.67%). In patients without metamorphopsia, abnormal macula could be found in 2 by OCT while nothing special was seen in FFA. Most abnormal macula in patients followed-up 2 months, 6 months and 1 year postoperatively meliorated as time went by, with alleviative or disappeared metamorphopsia; while the patients with persistently existing macular membrane had aggravating metamorphopsia. Conclusions Abnormal macula is the main reason for metamorphopsia after scleral buckling surgery. Neuroepithelium detachment and macular membrane are the main causes of metamorphopsia at the early and terminal stage after operation.

Objective To study the effects of ephedrine and phenylepbedrine for maintenance of arterial pressure during combined spinai/epidural anesthesia (CSEA) for caesarean section. Methods Forty patients, ASA grade Ⅰ - Ⅱ, who were scheduled for caesarean section by CSEA were randomly divided into two groups, when patients were hypotension, phenylephedrine 100 μg (group P, 20 cases ) or ephedrine 10 mg (group E, 20 cases). The variety of blood pressure (Bp), heart rate (HR) and oxyhemoglobin saturation (SpO2) were monitored; recorded before anesthesia (T0), at 15 min after anesthesia (T1), fetuses were taken out of uterus (T2) and at the end of operation (T3); umbilical arterial blood gas analysis was monitored; neonatal Apgar score was investigated. Results Umbilical arterial blood gas analysis of pH,PaO2, PaCO2, HCO3-, SaO2 were normal in two groups, there were no significant difference in PaO2, PaCO2 and SaO2 between two groups, but pH and HCO3- in group P were higher than those in group E [7.38±0.07 vs7.30±0.02 and (21.5±3.4) mmol/L vs (19.3±3.3) mmol/L] (P <0.05). There were no significant difference in Apgar score and Bp between two groups. Compared with group P, the HR in group E was increased obviously at T1 and T2 (P < 0.05). Conclusion Phenylephedrine is the vasopresser that most closely meets the criteria for the best vasopressor to use in obstetric patients.
