ObjectiveTo study the necessity of treating prolapse of lumbar intervertebral disc by active movement treatment. Methods68 patients with prolapse of lumbar intervertebral disc were divided into the group of active movement treatment (31 cases) and the control group (37 cases). One year later, the recurrence rate and F wave motor nerve conduction velocity of two groups were compared. ResultsThere is a lower recurrence rate (P<0.05) and a faster F wave motor nerve conduction velocity (P<0.01) in the group of active movement treatment compared with the control group. F wave motor nerve conduction velocity of the group of active movement treatment is also faster than that of 1 year ago (P<0.001). Conclusions It is necessary for patients with prolapse of lumbar intervertebral disc doing active movement.

In the present study, a new compound named 17-(6-cinnamamido-hexylamino-)-17-demethoxygeldanamycin (CDG) was obtained by introducing the cinnamic acid (CA) group into the 17-site of geldanamycin (GDM). The anti-cancer effects of CDG in vitro and in vivo were evaluated. MTT assay was used to examine the inhibitory effect of CDG on the proliferation of MCF-7, HepG2, H460 and SW1990 cells. Immunofluorescent staining flow cytometry combined with Annexin V-FITC/PI staining were used to detect apoptotic cells. Transwell assay was used to analyze the effect of CDG on cell invasion and migration ability. Western blotting was used to detect the expression levels of RAF-1, EGFR, AKT, CDK4 and HER-2 of MCF-7, HepG2 and H460 cells. The toxicities of CDG and GDM were evaluated in mice. Using the subcutaneously transplanted MCF-7 xenograft in nude mice, inhibitory effect was evaluated in vivo. The results showed that CDG inhibited the proliferation of cancer cells (IC50: 13.6-67.4 microg.mL-1). After exposure to CDG for 48 h, most cells presented typical morphologic changes of apoptosis such as chromatin condensation or shrunken nucleus. The rates of apoptosis of MCF-7, HepG2, H460 and SW1990 cells incubated with 10 microg.mL-1 CDG were 23.16%, 27.55%, 22.21%, 20.47%, respectively. A dose-dependent reduction of migration of four cell lines was found after exposure to CDG. The decreased levels of RAF-1, EGFR, AKT, CDK4 and HER-2 showed that CDG possessed HSP90 inhibitory effect. The result of animal toxicity test on the mice suggested that CDG had lower toxicity than GDM. Meanwhile, CDG inhibited the growth of MCF-7 xenografts of athymic mice.

OBJECTIVETo observe the clinical efficacy of Qi-supplementing and blood-activating (QSBA) in treating diabetic peripheral nephropathy (DPN).
METHODSSixty-eight type 2 diabetes mellitus patients with Qi deficiency-blood stasis Syndrome were randomly divided into two groups, the neurotrophic agents were used in both groups, while QSBA herbs were used in the treated group additionally. The treatment course was 2 months. Blood glucose (BG), triglyceride (TG), total cholesterol (TC) and nerve conduction velocity (NCV) were detected before and after treatment.
RESULTSAfter treatment, the BG, blood lipid, NCV were improved significantly (P < 0.05) in both groups, but the improvement was more significant in the QSBA treated group than in the control group (P < 0.05).
CONCLUSIONQSBA, in treating DPN, can not only improve its symptoms, but also ameliorate the NCV.

OBJECTIVETo provide objective data for position and orientation of zygomatic-area implant used in zygo-buccal flange osseointegrated implant obturator for patients with large maxillary defect.
METHODSFifty cases of normal unilateral zygomatic body with dentition were measured on three-dimensional spiral CT images. Measurements included the slope angle of zygomatic body on sagittal sectional image, the maximal horizontal distance from the buccal boundary of maxillary alveolar to outboard of maxillary sinus. Furthermore, the configuration of zygomatic body was observed on coronal sectional image.
RESULTSThe average rearward slope angle of zygomatic-body was 80.03 degrees. Forty-eight cases showed straight zygomatic-body configurations and two cases quite curvy. The maximal horizontal distance from the buccal boundary of maxillary alveolar to outboard of maxillary sinus was 6.77 mm.
CONCLUSIONSIn a normal condition, implants can be upright inserted tilting about 10 degrees ahead to utilize much zygomatic bone-volume in high site. In order to improve security and validity of implantation, it is better to take spiral CT examination to evaluate the bone volume and shape of zygomatic body before zygomatic-area implant.

Objective To investigate the role of ?7nAChR in the pathogenesis of Alzheimer's disease(AD)through exploring the relationship between ?7nAChR and A?_(1-42) in AD brains.Methods The accumulation of ?7nAChR and the possible relationship between ?7nAChR and A?_(1-42) were observed in 3 clinically and pathologically confirmed AD brains by immunohistochemistry. 3 normal brains were set as controls.Results Respective staining of anti-?7nAChR and anti-A?_(1-42) showed that the abnormal accumulation of ?7nAChR existed in AD brains. The main location was at hippocampus and temporal cortex which was just in accordance with senile plaque consisted mainly of A?_(1-42). The major part of ?7nAChR was located extra-cellular and within senile plaque from the view of morphology. No accumulation of ?7nAChR existed in normal brains. Co-staining of anti-?7nAChR and anti-A?_(1-42) further showed that ?7nAChR and A?_(1-42) could accumulate together in senile plaque of AD brain. The average rate of positive co-staining in hippocampus, temporal lobe and frontal lobe is 57.8%, 51.0% and 21.8% respectively. The accumulation of ?7nAChR in hippocampus and temporal lobe seems much than that in the frontal lobe. Conclusion ?7nAChR may combine with A?_(1-42) in AD brains. It is suggested that the combination should destroy the ?7nAChR receptor, block the receptor or mediate the injury of cholinergic neurons with the result of recognition and memory impairment and that ?7nAChR might play an important role in the pathogenesis of Alzheimer's disease.
