This study was aimed to optimize the vacuumextraction technology of alkaloids fromSophora alopecuroides. The orthogonal test and comprehensive evaluation were used to optimize the vacuumextraction technology. Contents of total alkali and oxymatrinewere used as index components for optimizing the effect of three factors, which were the adding amount of water, extraction time, and extraction frequency. Comparison was made among optimal conventional extraction process, decoction extraction and vacuumextraction. The results showed that the optimum extraction process was to add 12 times amount of water, and to extract for 3 times under the temperature of 60℃, 1h for each time. It was concluded that the optimized extraction vacuum technologyof alkaloids fromS. alopecuroidsdecompression total alkali content and oxymatrine process was better than that of optimal conventional extraction process and decoction extraction. The vacuumextraction technology was stable and practical.

Objective To detect the difference of the light sensitivity in the central visual field between normal people and type Ⅱ diabetic patients without diabetic retinopathy , and evaluate the effect of perimetric examination in early diagnosis of diabetic retinopathy. Methods The light sensitivity at the 80 locations in the central field was measured by Dicon field analyzer (model TKS 4000) in 76 normal eyes of 44 normal volunteers aged from 45 to 72 years and 75 eyes of 40 type Ⅱ diabetic patients without retinopathy aged from 46 to 71 years. Results For the diabetic patients without diabetic retinopathy, the light sensitivity of locations decreased by 4 8 dB,and there were some decreased light sensitivity areas. The mean light sensitivity of three zones of the central field had significant reduction in the diabetic patients as compared with the control group( P

AIM: To induce preconditioning and oxidative stress by H_2O_2 in HepG2 cells. METHODS: The different doses of H_2O_2 were used to induce apoptosis in HepG2 cells, which was estimated by AO/EB staining, MTT assay and flow cytometry. RESULTS: The different group of HepG2 cells stained with AO/EB showed different staining state. The high dose of H_2O_2 resulted in the increase in apoptosis rate of HepG2 cells and made MTT activity decreased. However, after pretreated with low dose of H_2O_2, the apoptosis rate was decreased and MTT activity was increased. CONCLUSION: The high dose H_2O_2 induced apoptosis in HepG2 cells and the low dose H_2O_2 protected HepG2 cells against the oxidative stress.

Objective To explore the best way for reconstruction of local defect after subtotal or extended resection of the temporal bone. Method The reconstruction of 33 patients who had undergone subtotal or extended resection of temporal bone between July 1993 to June 2003 in our hospital were retrospectively analysed. Results Thirty-three patients, aged 14-69 years old (average 45.0) were enrolled. Among them, 26 were suffering from malignancy (12 with recurrences, undergoing several operations). Subtotal resection of temporal bone was performed in 22 cases and extended resection in 11. Total survival rate of reconstructive tissues was 81.8%(27/33), in which pectoralis major island musculocutaneous flap accounted for 77.8%(7/9), temporalis musculocutaneous flap survived 100% (9/9), pedicled temporalis musculocutaneous flap associated with other local musculocutaneous flap survived 100%(4/4), 60.0% (3/5) of upper sternocleidomastoid musculocutaneous flap survived, and 66.7% (4/6) of fat transplantation survived. Nature and extent of the diseases, preoperative radiotherapy, relapse and postoperative leakage of cerebrospinal fluid were important influential factors for postoperative healing. Conclusions Reconstructive measures depended on the nature and extent of diseases, necessary size of tissue, local circulation, and influential factors of healing. The optimum way for the repair of a small defect after resection of non-malignant tumor was fat transplantation with dermis, and pedicled temporalis musculocutaneous flap for malignant tumors. Pectoralis major island musculocutaneous flap was employed in large defect and that with lack of blood supply. Skin grafting met several failures in these patients. Theoretically, free scapular skin flap is the optimum way for defects after subtotal or extended resection of temporal bone.

Objective To explore the relationship between operation scores and the expression of caveolin-1 ( Cav-1 ) protein in the cortex of mice.Methods Male Kunming mice were used and divided into two groups (excellent group and bad group) according to the training scores after 4 days' Y-maze learning training.The expression of cav-1 protein in cortex and hippocampus of the mice with different scores were measured through Western blot technology.Results Cav-1 protein expression of excellent group( Cav-1/β-actin was 5.71 + 1.11 ) in the cortex was significantly higher than that of the bad group ( Cav-1/β-actin was 1.69 + 0.20) (P ＜ 0.01 ).While there was no significant difference in the two groups in the expression of Cav-1 protein in hippocampus(P ＞ 0.05 ).Conclusion The operation scores have distinct correlation with the expression of Cav-1 protein in the cortex of mice.

Objective To explore the anti-inflammatory and analgesic effects of Shuangwu numbness-relief decoction. Methods The anti-inflammatory effect was assessed by xylene-induced mouse auricular swelling and peritoneal capillary permeability;and the analgesic effect was assessed by hot plate method and acetic acid-induced twisting method. Results Shuangwu numbness-relief decoction at moderate or high dose had a significant inhibitory effect on mouse auricular swelling, with a significant difference as compared with the control group (P<0.01);the decoction at low , moderate , or high dose group played a marked inhibitory role in the increase in mouse peritoneal capillary permeability (P<0.01). Shuangwu numbness-relief decoction at moderate or high dose effectively reduced the writhing frequency in mice (P < 0.01). The decoction at high dose increased the pain threshold in mice one hour after intragastric administration (P < 0.05), and the decoction at moderate or high dose increased the pain threshold two hours after administration (P < 0.05). Conclusions Shuangwu numbness-relief decoction has an obvious anti-inflammatory and analgesic effect.

Objective To analyze the characteristics of gastroesophageal junction(GEJ) in gastroesophageal reflux disease (GERD) using high resolution manometry (HRM),and the features in different GERD subtypes,reflux esophagitis (RE) and non-erosive gastrooesophageal reflux disease (NERD).Methods Sixty GERD patients were divided into two subtypes,RE (n =33) and NERD(n =27),based on the results of endoscopy.All patients received HRM,and were divided into three subtypes,type Ⅰ,type Ⅱ and type Ⅲ according to the GEJ pressure morphology.HRM results among different subtypes were investigated.Results In 60 GERD patients,the GEJ was divided into three subtypes,including 26 cases of type Ⅰ (RE =14,NERD =12),29 cases of type Ⅱ (RE =14,NERD =15) and 5 cases of type Ⅲ (RE =5).The characteristics of GEJ morphologic subtypes were analyzed.The total length of lower esophageal sphincter(LES) of three GEJ subtypes(type Ⅰ,type Ⅱ and type Ⅲ) were (3.35 ± 0.56) cm,(3.29 ± 0.87) cm and(2.43 ± 0.22)cm,respectively.The LES intra-abdominal length of three GEJ subtypes were(2.41 ± 0.68) cm,(3.07 ± 4.59) cm and (0.00 ± 0.00) cm,respectively.The LES rest pressure of three GEJ subtypes were (22.00 ± 8.00) mmHg,(16.46 ± 8.60) mmHg and (11.07 ± 5.80) mmHg,respectively.The total length of LES were significantly different among three subtypes (P ＜ 0.05).The LES rest pressure were not significantly different among three subtypes (P ＞ 0.05).Among type Ⅰ and type Ⅱ patients,there were no significant difference in LES-CD distance,total length of LES,LES intra-abdominal length and LES rest pressure between RE group and NERD group.Conclusion HRM can clearly distinguish the GEJ subtypes.To some extent,esophageal motility characteristics of the patients with different subtypes GEJ is various.However,it still needs further studies with larger sample size to confirm.
