OBJECTIVETo compare the efficacy difference between acupuncture and western medication in the treatment of knee osteoarthritis.

METHODSOne hundred and twenty cases were randomly divided into an acupunc ture group and a western medication group, 60 cases in each group. In acupuncture group, acupuncture was applied mainly to Neixiyan (EX-LE 4), Dubi (ST 35), Yinlingquan (SP 9) and Yanglingquan (GB 34) and to the other acupoints selected according to syndrome differentiation. In western medication group, Glucosamine Hydrochloride capsules were applied for oral administration, 2 capsules each time, 3 times per day. Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)and Medical Outcomes Study 36-Item Short Form Health Survey (SF-36, Chinese version) were used to assess the therapeutic effect before treatment, after 4 weeks treatment and in follow-up visit of 9 weeks after treatment separately.

RESULTSAfter 4 weeks treatment, the total effective rate was 86.7% (52/60) in acupuncture group and was 88.3% (53/60) in western medication group, indicating no statistical significant difference in the comparison between two groups (P > 0.05). In 9 weeks after treatment, the total effective rate was 83.3% (50/60) in acupuncture group, which was better than 61.7% (37/60, P < 0.05) in western medication group. The scores of WOMAC and SF-36 were all improved after treatment as compared with those before treatment in two groups (P < 0.05, P < 0.01). There were no significant differences in comparison between two groups after 4 weeks treatment (all P > 0.05). But, in follow-up visit of 9 weeks after treatment, the scores of WOMAC and SF-36 in acupuncture group were superior to those in western medication group (P < 0.05, P < 0.01).

CONCLUSIONThe short-term efficacies on osteoarthritis of knee in acupuncture group according to syndrome differentiation are similar to that of oral adiministration of Glucosamine Hydrochloride, but the long-term efficacy in acupuncture group is better than that in western medication group.

OBJECTIVETo evaluate the efficacy and safety of argon plasma coagulation (APC) in the treatment of large airway obstruction.

METHODSTotally 389 patients with treacheobronchial stenosis were treated with APC (ARCO3000 type) by bronchoscopy. The stenoses were caused by carcinomas (203 cases, 52.2%), metastatic tumors (67 cases, 17.2%), benign tumors (18 cases, 4.6%), granulomas (93 cases, 23.9%) and other lesions (8 cases, 2.1%). The rate of recanalization, relief of the symptoms, and complications were analyzed.

RESULTS1121 times of APC treatment were performed in the 389 patients. Complete recanalization was achieved in 138 cases (35.5%), partial in 143 (36.8%), mild in 55 (14.1%) and none in 53 (13.6%). The major complications included: super-ventricular tachycardia in 136 cases (34.9%), bleeding in 51 (13.1%), decrease in blood oxygen saturation in 48 (12.3%), asphyxia in 33 (8.5%), ventricular or super-ventricular arrhythmia in 24 (6.2%), short-term aggravation of airway obstruction in 18 (4.6%), and tracheal perforation in 3 (0.78%). All those complications were treated with various measures and no patient died of the complications during the procedure.

CONCLUSIONArgon plasma coagulation is effective and relatively safe in relieving the obstruction and dyspnea in patients with large airway obstruction caused by various reasons. However, for the patients with severe airway obstruction, argon plasma coagulation sometimes may cause severe or even lethal complications. Critical consideration of the indication, operators' skill and taking more precautions during the procedure are required to ensure the safety of argon plasma coagulation treatment.

OBJECTIVETo study the ultrastructural changes of the rat convoluted seminiferous tubule after alcohol consumption.

METHODSForty-eight Wistar mature male rats were divided into two groups randomly: control group (A) and experimental one (B). 6 ml/(kg x d) of 50 degrees alcohol was perfused through the gastric tube for 39 days in Group B; and 6 ml/(kg x d) of normal saline was supplemented in Group A. The ultrastructure of the rat convoluted seminiferous tubule was observed by transmission electron microscope at day 14, 27 and 40.

RESULTSIn Group A, the pykno-basement membrane was unstriated and uniform, Sertoli cells showed cytoplasmic profusion, with big nucleus, well-distributed nucleoplasm, distinct nucleolus, more mitochondria and plain hierarchical tight-junction. And the ultrastructure of the rat convoluted seminiferous tubule in Group B began to change at the end of the first spermatogenic cycle (D 14) and changed more and more evidently with the ethanol administration, mainly as follows: (1) more lysosomes and vacuolisation found in Sertoli cells, and organelles decreased and blurry; (2) more and bigger vacuoles among the spermatogonia, Sertoli cells and basement membrane; (3) obvious apoptosis of spermatogonia and apoptotic bodies aggregated near the membrane; (4) more cytoplasm and vacuolisation in the sperm of the convoluted seminiferous tubule, and disarranged, deleted or clustered mitochondria in the sperm tail; (5) blurry and rigid tight-junction; (6) thickened, wrinkled or broken basement membrane and under-basement

CONCLUSIONAlcohol can cause ultrastructural changes of the basement membrane, tight-junction and Sertoli cells of the membrane. rat convoluted seminiferous tubule and apoptosis of spermatogonia.

OBJECTIVETo study the efficacy of self-made, antibiotic-loaded cement articulating spacer in the treatment of infected total knee arthroplasty.

METHODSThe self-made molds were used to form the spacer during the operation. From March 2002 to March 2007, 22 patients with infected knee arthroplasty (10 males with 10 knees, 12 females with 12 knees) were treated with this kind of spacer in our center. The mean age of the patients was 59.6 years old (33 to 75 years old). The interval time between primary arthroplasty and first onset of infective syndrome was 6.7 months (1 to 14 months). The diagnosis was established by the clinical presentation,serum laboratory inflammatory markers (white blood cell count,erythrocyte sedimentation rate and C-reactive protein) and knee aspiration. The serum laboratory inflammatory markers were used to measure the systemic response to infection. Clinical and radiographic follow-up was regularly performed by HSS score system and X-ray.

RESULTSAll the patients were followed, the average interval between debridement and reimplantation was 4.7 months (3 to 9 months) and the infection control rate was 100% after the implantation of spacer. The average follow-up duration after reimplantation was 29.8 months (10 to 64 months) and there was no recurrence of infection at the latest follow-up. The HSS score increased from 40.5+/-5.9 to 65.8+/-7.5 after the implantation of spacer, furthermore, the score reached 88.7+/-5.1 in average at the latest follow-up. The patient satisfaction rate was 95.3%.

CONCLUSIONThis self-made molds and spacers is a reliable approach for the management of infected knee arthroplasty with some virtues, such as providing a mobile and functional joint through the treatment course, decreasing the difficulty of reimplantation, avoiding of a long-term post-operative infusion and high effective for eradicating infection.

To investigate the dynamic change of lipid peroxidation-related protein expression and the intervention effects of Yiguanjian (YGJ) Decoction on liver fibrosis induced by CCl4 in rat. Fifty-seven male Wistar rats were randomly divided into a liver fibrosis group (n = 39) and a normal group (n = 18). The liver fibrosis was treated with peritoneal injection of 50% CCl4 for nine weeks. At the end of weeks 3 and 6 of CCl4 treatment, six rats were sacrificed to assess the status of liver fibrosis. At the end of week 7, the remaining -fibrotic rats were randomly divided into an untreated model group (M, n=15) and a YGJ-treated group (n = 12). The YGJ group was administered daily, oral YGJ Decoction for three weeks, concomitant with continued CCl4 treatment. The M group and normal group received the same treatment oral regimen and volume of distilled water. At the end of week 8, four rats in group M were sacrificed to observed the fibrosis status. At the end of week 9, the fibrotic rats were sacrificed for sampling. Liver function, histological changes, contents of hydroxyproline (Hyp) and malondialdehyde (MDA), activity of super oxidase dismutase (SOD) and L-glutathione (GSH), protein expression of heat shock protein (HSP)70, heme oxygenase (HO)-1, transferrin, peroxiredoxin (Prxd) 6 and liver fatty acid binding protein (L-FABP) were detected. Compared with normal group-, the MDA content was increased significantly in M group at week 6 (M: 4.23+/-0.45 nmol/mg vs. normal: 2.22+/-0.59 nmol/mg, F = 60.13, P less than 0.01) and week 9 (M: 6.29+/-1.23 nmol/mg vs. normal: 2.22+/-0.59 nmol/mg, F = 66.99, P less than 0.01), but the SOD activity was decreased significantly at the same time points [week 6: (M: 196.94+/-39.20 U/mg vs. normal: 264.50+/-30.44 U/mg, F = 11.12, P less than 0.01]); [week 9: (M: 152.2+/-51.65 U/mg vs. normal: 264.50+/-30.44 U/mg, F = 23.11, P less than 0.01)], as were the GSH content [week 6: (M: 48.47+/-7.27 nmol/mg vs. 60.74+/-9.04 nmol/mg, F = 6.71, P less than 0.05]]; [week 9: (M: 37.89+/-9.01 nmol/mg vs. 60.74+/-9.04 nmol/mg, F = 24.06, P less than 0.01]]. Compared with group M at week 9, the YGH-treated model group had markedly decreased MDA (YGJ: 4.25+/-0.86 nmol/mg vs. M: 6.29+/-1.23 nmol/mg, F = 19.52, P less than 0.01], but significantly increased SOD (YGJ: 198.35+/-46.48 U/mg vs. 152.21+/-51.65 U/mg, F = 4.65, P less than 0.05] and GSH (YGJ: 53.73+/-7.54 nmol/mg vs. M: 37.89+/-9.01 nmol/mg, F = 19.23, P less than 0.01). Compared to normal rats at week 9, group M had significantly higher protein levels of HSP70 (normal: 1.21+/-0.06 vs. M: 0.58+/-0.07, F = 166.87, P less than 0.01) and HO-1 (normal: 1.11+/-0.06 vs. M: 0.58+/-0.06, F = 123.96, P less than 0.01), but significantly decreased levels of Prxd6 (normal: 0.04+/-0.05 vs. M: 1.49+/-0.05, F = 1215.85, P less than 0.01), transferrin (normal: 0.67+/-0.03 vs. M: 1.67+/-0.04, F = 301.35, P less than 0.01), and L-FABP (normal: 0.24+/-0.02 vs. M: 1.44+/-0.14, F = 219.05, P less than 0.01). Compared to group M at week 9, the YGJ treatment group showed significantly reduced HSP70 (YGJ: 0.82+/-0.04 vs. M: 1.21+/-0.06, F = 92.31, P less than 0.01) and HO-1 (YGJ: 0.90+/-0.04 vs. 1.11+/-0.06, F = 26.89, P less than 0.01), but significantly increased Prxd6 (YGJ: 0.88+/-0.11 vs. 0.04+/-0.05, F = 150.17, P less than 0.01), transferrin (YGJ: 1.36+/-0.13 vs. 0.24+/-0.02, F = 237.19, P less than 0.01), and L-FABP (YGJ: 1.04+/-0.12 vs. 0.67+/-0.03, F = 27.53, P less than 0.01). YGJ treatment of fibrotic liver rats reduces lipid peroxidation damage by preventing generation of oxidizing substances.

OBJECTIVETo investigate the value of 11C-PD153035 as an EGFR imaging agent in C6 tumor-bearing rat.

METHODSThe tumor-bearing rats were generated by subcutaneous injection of glioma C6 cells. Positron emission tomography/computer tomography (PET/CT) scans started as soon as intravenous injection of 11C-PD153035 (15-20 MBq/0.3 ml) was completed, images were collected continuously. The region of interest (ROI) was used to study the percentage of radioactivity in major organs and implanted tumors in the rats. The accumulation and blocking study in vitro was completed.

RESULTSThere were significant differences in 11C-PD153035 uptake among major organs. The maximum uptake in the organs ranked in the following order: liver > gastrointestinal tract > kidney > lung > brain > muscle. Radioactivity could be also observed in the tumors. The radioactivity ratio (T/NT, target/non-target) peaked (4.15) at 40 - 50 min post injection. The in vitro blocking study showed that 11C-PD153035 uptaken by C6 cells could be blocked by PD153035.

CONCLUSIONThe results of this study show that 11C-PD153035 can be uptaken by EGFR-expressing tumors. 11C-PD153035 has a potential as a bioprobe to yield useful information for both diagnosis and therapy of tumors. However, the high concentration of 11C-PD153035 in the gastrointestinal tract is unfavorably affecting the tumor detection in these organs.
